[0057] In some embodiments, the dust collection hood 2800 further includes a stopper 2825. The stopper 2825 is arranged on the dust collection hood wall 2820, and the stopper 2825 may cooperate with a limiting portion arranged in the dust collection chamber 2100, such that the dust collection hood 2800 is firmly placed on the dust collection chamber 2100 without shaking. The limiting portion may be arranged on at least one of the dust collection chamber rear wall 2134 and the dust collection chamber side walls. The stopper 2825 and the limiting portion are arranged in pairs and match each other. In the embodiment shown in FIG. 4, the stopper 2825 is arranged on the second side wall 2822 of the dust collection hood, and the limiting portion corresponding to the stopper 2825 is arranged on the second dust collection chamber side wall 2132. The stopper 2825 abuts against the limiting portion in response to the dust collection hood 2800 being placed on the dust collection chamber 2100.

[0058] In some embodiments, at least one of the dust collection chamber bottom wall, the circumferential inner wall 2150 and the dust collection hood wall 2820 is provided with a supporting rib 2826. The supporting rib 2826 may be of a strip-shaped structure which protrudes outward relative to a surface. In the embodiment shown in FIG. 4, the supporting rib 2826 is at least arranged on an inner surface of the second side wall 2822 of the dust collection hood, and a plurality of supporting ribs 2826 are arranged on the inner surface of the second side wall 2822 of the dust collection hood. By providing the supporting ribs 2826, the dust bag in the dust collection bin 3000 may not be attached to the dust collection chamber bottom wall, the circumferential inner wall 2150 and/or the dust collection hood wall 2820, such that an airflow can flow out of the dust bag without being affected by the attachment.

[0059] The present disclosure further provides a dust collection system, including an automatic cleaning device and the self-cleaning dust collection base described in the foregoing embodiments.

[0060] Owing to the design that the dust collection hood is placed on the dust collection chamber with the opening facing downwards, the dust collection hood and the dust collection chamber are combined more closely under the action of a fan, which further improves the dust collection efficiency. And, the exposed design of the dust collection hood makes it convenient for a user to visualize the situation inside the dust collection hood and deal with the dust collection chamber in a more timely manner, e.g., to replace the dust bag.

[0061] In the related art, due to a limited capacity of a dust box of an automatic cleaning device, a user often needs to bend down to clean the dust box, resulting in poor user experience. Therefore, an embodiment of the present disclosure provides a self-cleaning dust collection base. The garbage in the dust box of the automatic cleaning device is collected into the dust collection bin of the self-cleaning dust collection base by means of a dust collection system. By providing the dust bag support and the dust bag in the dust collection bin, the garbage in the dust box is basically transferred to the dust bag located in the dust collection bin without leakage, thus reducing the frequency of garbage disposal by the user and improving the user experience. In addition, the dust bag adopts a design that a fastening plate corporates with a sliding plate. When the dust bag is removed from the dust bag support, the sliding plate is in a closed position, preventing the garbage in the dust bag from being scattered in the dust collection bin.

[0062] Specifically, as an example of the self-cleaning dust collection base according to the embodiment of the present disclosure, FIG. 1 is a schematic diagram of an overall structure of the self-cleaning dust collection base, and FIG. 2 is a schematic structural diagram of a self-cleaning dust collection base body from which a sewage tank, a clean water tank and a dust collection hood are removed.

[0063] As shown in FIG. 1, a direction in which a self-cleaning dust collection base bottom plate 1000 protrudes from a self-cleaning dust collection base body 2000 is a forward direction, and a direction of a rear wall of the self-cleaning dust collection base body 2000 is a rearward direction. A dust collection bin 3000 is located on a left side of the self-cleaning dust collection base, a clean water tank 4000 is located on a right side of the dust collection bin 3000, and a sewage tank 5000 is located on a right side of the clean water tank 4000.

[0064] The self-cleaning dust collection base body 2000 is configured to collect garbage in the dust bag of the automatic cleaning device. In some embodiments, components such as the dust collection bin 3000, the clean water tank 4000, and the sewage tank 5000 may also be arranged side by side on the self-cleaning dust collection base body 2000. Specifically, as shown in FIG. 2, the self-cleaning dust collection base body 2000 includes a water storage chamber 2700 and a dust collection chamber 2100. The water storage chamber 2700, with an opening facing upward and forward, is arranged at a top of the self-cleaning dust collection base body 2000. The water storage chamber may further include a clean water bin for accommodating the clean water tank 4000 and a sewage bin for accommodating the sewage tank 5000. The dust collection chamber 2100 (with an opening facing upward and forward) and the water storage chamber 2700 are arranged at the top end of the self-cleaning dust collection base body 2000 side by side. A dust collection hood 2800 that matches the opening of the dust collection chamber 2100 is arranged on the dust collection chamber 2100, and the dust collection hood 2800 is detachably placed on the dust collection chamber 2100. The dust collection chamber 2100 and the dust collection chamber 2100 jointly form the dust collection bin 3000. The upward and forward designs of the water storage chamber 2700 and the dust collection chamber 2100 facilitate installment and removal of the sewage tank 5000, the clean water tank 4000 and the dust collection hood 2800.

[0065] A body base 6000 is arranged at a lower portion of the self-cleaning dust collection base body 2000. In some embodiments, the body base 6000 is integrally arranged at the lower portion of the self-cleaning dust collection base body 2000. The body base 6000 also abuts against the self-cleaning dust collection base bottom plate 1000. Specifically, the self-cleaning dust collection base bottom plate 1000 and the body base 6000 are arranged in sequence in a second direction, and the second direction is a direction opposite to the arrow of the front-rear axis X.

[0066] A dust collection port 6100 is formed in the body base 6000 and substantially located at an edge of the body base 6000 connected to the self-cleaning dust collection base bottom plate 1000. The dust collection port 6100 is configured to interface with a dust outlet of the automatic cleaning device, and the garbage in the dust box 300 of the automatic cleaning device enters the dust collection chamber 2100 of the self-cleaning dust collection base body 2000 through the dust collection port 6100. In some embodiments, a sealing rubber gasket is also arranged around the dust collection port 6100 and configured to seal the dust collection port 6100 and the dust outlet of the automatic cleaning device after the dust collection port 6100 interfaces with the dust outlet of the automatic cleaning device so as to avoid leakage of the garbage.

[0067] In some embodiments, the body base 6000 further includes a cleaning tank 6200. The cleaning tank 6200 is configured to clean cleaning component(s) on the automatic cleaning device, for example, to replenish a wet cleaning module of the automatic cleaning device with a cleaning fluid, and/or to accommodate sundries removed from the wet cleaning module, and/or to collect sewage generated in the process of cleaning the wet cleaning module, so as to facilitate subsequent treatment of the sundries and sewage. In some embodiments, the cleaning tank 6200 is arranged behind the dust collection port 6100.

[0068] In some embodiments, the self-cleaning dust collection base further includes an air duct, one end of the air duct is communicated with the dust collection port 6100 of the body base 6000, and the other end of the air duct is communicated with the dust collection chamber 2100. When the self-cleaning dust collection base is in a state of dust collection, sufficient negative pressure is formed in the dust collection bin 3000 to suck the garbage in the dust box 300 into the dust bag in the dust collection chamber 2100 through the dust collection port 6100 and the air duct.

[0069] FIG. 6 is a schematic structural diagram of a dust bag support according to some embodiments of the present disclosure, in which a sliding baffle is in a first position; and FIG. 7 is another schematic structural diagram of the dust bag support according to some embodiments of the present disclosure, in which the sliding baffle is in a second position.

[0070] Referring to FIGS. 1 to 2, in some embodiments, the self-cleaning dust collection base further includes a dust bag support 2110, and the dust bag support 2110 is configured to install the dust bag. The dust bag support 2110 is arranged in the dust collection bin 3000, for example, arranged on an inner side wall of the dust collection bin 3000 by means of a fixing component, for example, a screw, or fixed to a bottom surface of the dust collection bin 3000 by the bottom of the dust bag support 2110.

[0071] The dust bag support 2110 is internally provided with a hollow cavity, and the hollow cavity is used as a part of the air duct of the self-cleaning dust collection base, for example, as a tail end of the air duct.

[0072] The dust bag support 2110 includes a support side wall 2111 facing the inside of the dust collection bin 3000, and the support side wall 2111 is provided with a dust outlet port 2112. The dust outlet port 2112 is communicated with the dust collection port 6100 by means of the air duct, and the air duct is configured to guide the garbage into the dust collection bin 3000, for example, into the dust bag in the dust collection bin 3000. The dust outlet port 2112 is configured to be communicated with an inlet of the dust bag, for collecting the garbage into the dust bag.

[0073] The dust bag support 2110 further includes a sliding baffle 2113 capable of sliding on the support side wall 2111. The sliding baffle 2113 is configured to be switchable between a first position and a second position. The sliding baffle 2113 shields the dust outlet port 2112 in response to the sliding baffle 2113 being in the first position, and the sliding baffle 2113 exposes the dust outlet port 2112 in response to the sliding baffle 2113 being in the second position. The dust bag is a consumable item detachably installed in the dust bag support 2110. With this design, when the dust bag is not installed in the dust bag support 2110, the sliding baffle 2113 may shield the dust outlet port 2112, and isolate the dust collection bin 3000 from the air duct, so that a suction force generated by the fan cannot enter the air duct from the dust collection bin, which prevents the garbage from entering the dust collection bin 3000 where the dust bag is not installed.

[0074] FIG. 8 is a schematic structural diagram of a dust bag according to some embodiments of the present disclosure, in which a sliding plate is in a closed position. FIG. 9 is another schematic structural diagram of the dust bag according to some embodiments of the present disclosure, in which the sliding plate is in an open position. FIG. 9A is a schematic diagram of a partial structure of the dust bag according to some embodiments of the present disclosure. FIG. 9B is a schematic structural diagram of a cross-section in FIG. 9A. FIG. 9A shows a cross-section of the dust bag, while the dust bag is not shown in FIG. 9 or FIG. 9B.

[0075] In some embodiments, as shown in FIGS. 8 to 9B, the present disclosure further provides a dust bag 2120. The dust bag 2120 is configured to be detachably installed on the dust bag support 2110 for collecting the garbage.

[0076] The dust bag 2120 includes a dust bag body 2121, a fastening plate 2122 and a sliding plate 2123. The dust bag body 2121 is made of, for example, a material that is breathable but can filter fine particles, such as a non-woven fabric or a paper material, and the dust bag body 2121 is configured to accommodate the garbage. The fastening plate 2122 is fixedly connected to the dust bag body 2121. The fastening plate 2122 is provided with a fastening plate opening 21221, and the fastening plate opening 21221 serves as an inlet of the dust bag body 2121. The sliding plate 2123 is slidably connected to the fastening plate 2122 and configured to be switched between the closed position and the open position. The sliding plate 2123 shields the fastening plate opening 21221 in response to the sliding plate 2123 being in the closed position, and the sliding plate 2123 exposes the fastening plate opening 21221 in response to the sliding plate 2123 being in the open position.

[0077] Specifically, as shown in FIGS. 8 and 9, the sliding plate 2123 is provided with a sliding plate opening 21231. In response to the sliding plate 2123 being in the closed position, an orthographic projection of the sliding plate opening 21231 on the fastening plate 2122 does not overlap with the fastening plate opening 21221, and the sliding plate 2123 shields the fastening plate opening 21221, as shown in FIG. 8. In response to the sliding plate 2123 being in an open position, an orthographic projection of the sliding plate opening 21231 on the fastening plate 2122 at least partially overlaps with the fastening plate opening 21221, and the sliding plate 2123 exposes at least a part of the fastening plate opening 21221 through the sliding plate opening 21231, as shown in FIG. 9.

[0078] In some embodiments, a size of the sliding plate opening 21231 is, for example, larger than that of the fastening plate opening 21221, and the orthographic projection of the sliding plate opening 21231 on the fastening plate 2122 covers the fastening plate opening 21221 in response to the sliding plate 2123 being in the closed position. In some embodiments, the size of the sliding plate opening 21231 is, for example, smaller than that of the fastening plate opening 21221, and the orthographic projection of the sliding plate opening 21231 on the fastening plate 2122 falls within the fastening plate opening 21221 in response to the sliding plate 2123 being in the closed position. In some embodiments, the size of the sliding plate opening 21231 is, for example, equal to that of the fastening plate opening 21221, and the orthogonal projection of the sliding plate opening 21231 on the fastening plate 2122 substantially coincides with the fastening plate opening 21221 in response to the sliding plate 2123 being in the closed position.

[0079] The sliding fit between the sliding plate 2123 and the fastening plate 2122 allows the inlet of the dust bag to be closed to prevent the garbage in the dust bag from leakage.

[0080] In some embodiments, as shown in FIGS. 8 to 9B, an edge of the fastening plate opening 21221 is provided with a flexible rubber ring 21224 that protrudes toward the sliding plate 2123. In response to the sliding plate 2123 being in the open position, the flexible rubber ring 21224 passes through the sliding plate opening 21231 and protrudes in a direction away from the sliding plate 2123, so that when the sliding plate opening 21231 interfaces with the fastening plate opening 21221, a slit at the position where the two openings of the sliding plate 2123 and the fastening plate 2122 interface with each other is blocked to make the sliding plate opening 21231 and the fastening plate opening 21221 interface with each other in a sealing manner. In response to the sliding plate 2123 being not in the open position, for example, being in the closed position, at least a part of the flexible rubber ring 21224 may be squeezed between the sliding plate 2123 and the fastening plate 2122 to increase the friction therebetween, so that the sliding plate 2123 and the fastening plate 2122 can only slide relative to each other under the action of a certain external force, and the sliding plate 2123 can be stably kept in the closed position to prevent the garbage in the dust bag from being scattered.

[0081] In some embodiments, as shown in FIGS. 8 and 9, the sliding plate 2123 may slide relative to the fastening plate 2122 in a first direction M. The sliding plate 2123 includes a limiting bump 21243 arranged on at least one side of the sliding plate 2123, for example, on two sides of the sliding plate 2123. The number of the limiting bumps 21234 is, for example two, and the limiting bumps 21243 protrude from the sliding plate 2123 in a second direction perpendicular to the first direction M. The fastening plate 2122 includes limiting components 21223 arranged at two ends of the fastening plate 2122 in the first direction and configured to block the limiting bumps 21234 in the first direction M so as to prevent the sliding plate 2123 from disengaging from the fastening plate 2122. The number of the limiting components 21223 is, for example four, and the limiting components 21223 are symmetrically distributed on two sides of the fastening plate 2122. When the sliding plate 2123 slides relative to the fastening plate 2122, the limiting bumps 21234 may only move between the corresponding limiting components 21223 located at two ends of the fastening plate 2122 in the first direction.

[0082] In some embodiments, the sliding plate 2123 further includes a handle portion 21232 disposed at an end of the sliding plate in the first direction M and configured to be conveniently held by an operator to move the sliding plate 2123.

[0083] The dust bag 2120 is configured to be detachably installed on the dust bag support 2110. In response to the dust bag 2120 being installed on the dust bag support 2110, the sliding baffle 2113 is in the second position to expose the dust outlet port, the sliding plate is in the open position, and the fastening plate opening 21221 interfaces with the dust outlet port 2112. Based on the above arrangement, when the dust bag support 2110 is not installed in the dust bag 2120, the sliding baffle 2113 is in the first position, the dust outlet port 2112 is shielded, and a suction force generated by the fan cannot enter the air duct from the dust collection bin, thus preventing the garbage from entering the dust collection bin 3000 where the dust bag 2120 is not installed.

[0084] When the dust bag 2120 is removed from the dust bag support 2110, the sliding plate 2123 is in the closed position to prevent the garbage in the dust bag from being scattered in the dust collection bin. Moreover, the sealed dust bag also prevents the garbage in the dust bag from being scattered to an external environment.

[0085] When the dust bag 2120 is not installed in the dust bag support 2110, the sliding plate 2123 shields the fastening plate opening 21221 of the fastening plate 2122, so that when the dust bag is installed in the dust bag support 2110, the sliding baffle 2113 may be pushed from the first position to the second position and fixed in the second position under the cooperation of the sliding plate 2123 and the fastening plate 2122. When the dust bag 2120 is withdrawn from the dust bag support 2110, the sliding plate 2123 shields the fastening plate opening 21221 to avoid leakage of the garbage. The fastening plate opening 21221 (i.e., the inlet of the dust bag) interface with the dust outlet port 2112 after the dust bag 2120 is installed in the dust bag support 2110. Under the action of the airflow provided by the fan, the garbage in the dust box of the automatic cleaning device may be collected into the dust bag body 2121 through the dust collection port 6100 on the body base 6000, the air duct in the self-cleaning dust collection base, the dust outlet port 2112 on the dust bag support 2110 and the fastening plate opening 21221 on the dust bag 2120 in sequence.

[0086] FIG. 10 is a schematic diagram of a pre-assembled structure of the dust bag support and the dust bag according to some embodiments of the present disclosure, and FIG. 11 is a schematic diagram of an assembled structure of the dust bag support and the dust bag according to some embodiments of the present disclosure.

[0087] In some embodiments, as shown in FIGS. 6 to 11, the dust bag support 2110 includes a socket 2114, and at least a part of the sliding baffle 2113 is located in the socket 2114, so that the sliding baffle 2113 may slide in an extension direction X of the socket 2114, and thus be switched between the first position and the second position. The number of the sockets 2114 is, for example, one or more. As shown in FIGS. 6 to 11, the number of the sockets 2114 is, for example, two, and the sockets 2114 are respectively arranged at two opposite ends of the support side wall 2111 of the dust bag support 2110. The two sockets 2114 respectively accommodate the two opposite ends of the sliding baffle 2113, so that the sliding baffle 2113 may slide in the extension direction X of the socket 2114.

[0088] As shown in FIGS. 6 to 11, the fastening plate 2122 and the sliding plate 2123 of the dust bag 2120 are configured to be insertable into the socket 2114 to slide along the socket 2114 in the extension direction X, and the sliding baffle 2113 is pushed to slide in the extension direction X of the socket such that the dust bag 2120 is installed in the dust bag support 2110. Specifically, two ends of the fastening plate 2122 and the sliding plate 2123 of the dust bag 2120 may be respectively inserted into the two sockets 2114 described above. In response to the dust bag 2120 being installed on the dust bag support 2110, the sliding plate 2123 is in the open position to expose the fastening plate opening 21221, and the sliding baffle 2113 is in the second position to expose the dust outlet port 2112, so that the fastening plate opening 21221 interfaces with the dust outlet port 2112.

[0089] As shown in FIG. 10, in the process of installing the dust bag 2120 in the dust bag support 2110, the dust bag 2120 moves relative to the dust bag support 2110 in the extension direction X of the socket 2114. During the installment, the fastening plate 2122 and the sliding plate 2123 of the dust bag 2120 face the support side wall 2111 of the dust bag support 2110. In the process of inserting the fastening plate 2122 and the sliding plate 2123 into the socket 2114 in the extension direction X of the socket 2114, the sliding baffle 2113 may be pushed to move from the first position to the second position.

[0090] In some embodiments, a sliding baffle protrusion 21131 is arranged at a lower end of the sliding baffle 2113, and the sliding baffle protrusion 21131 is a strip-shaped protrusion along a lower edge of the sliding baffle 2113 toward the dust collection bin 3000. The lower end of the sliding plate 2123 may abut against the sliding baffle protrusion 21131 after the sliding plate 2123 is inserted into the socket 2114. Since the lower end of the sliding plate 2123 abuts against the sliding baffle protrusion 21131, the sliding baffle 2113 may also be pushed to slide in the extension direction X of the socket when the sliding plate 2123 slides downward in the extension direction X of the socket 2114. In some embodiments, a sliding plate protrusion 21233 is also arranged at the lower end of the sliding plate 2123, and the sliding plate protrusion 21233 may be a strip-shaped protrusion along the lower edge of the sliding plate 2123 toward the dust collection bin 3000. The sliding plate protrusion 21233 may exactly abut against the upper side of the sliding baffle protrusion 21131 after the sliding plate 2123 is inserted into the socket 2114. Since the sliding plate protrusion 21233 abuts against the sliding baffle protrusion 21131, the sliding baffle 2113 may also be pushed to slide in the extension direction X of the socket when the sliding plate 2123 slides downward in the extension direction X of the socket 2114.

[0091] FIG. 11 is a sectional view of an assembled structure of the dust bag support and the dust bag according to some embodiments of the present disclosure, and FIG. 12 is a schematic diagram of an assembled structure of the dust bag support and the dust bag according to some embodiments of the present disclosure.

[0092] As shown in FIG. 11 and FIG. 12, the socket 2114 is internally provided with a fastening portion 21141, for example, an elastic snap joint, which can move in an approximate arc line as shown by an arrow in FIG. 12. The fastening plate 2122 is provided with a fastening plate slot 21222 that matches the fastening portion 21141, and the fastening portion 21141 is snapped in the fastening plate slot 21222 in response to the dust bag 2120 being installed on the dust bag support 2110. The fastening plate 2122 slides to a snap-in position in the extension direction X of the socket 2114, the fastening plate opening 21221 interfaces with the dust outlet port 2112, and the fastening portion 21141 is cooperatively snapped with the fastening plate slot 21222, so that the dust bag 2120 is fixed to the dust bag support 2110.

[0093] A limiting bump 212234 on the sliding plate 2123 also serves as an unlocking bump 21234 (also referred to as the unlocking bump 21234), and is configured to squeeze, during withdrawal of the sliding plate 2123 from the socket 2114, the fastening portion 21141 to cause the fastening portion 21141 to disengage from the fastening plate slot 21222, so as to release the fastening plate 2122 from the fastening portion 21141 and make the dust bag 2120 successfully disengage from the dust bag support 2110. In some embodiments, the unlocking bump 21234 also has a limiting function and cooperates with the limiting component 21223 on the fastening plate 2122 to prevent the sliding plate 2123 from disengaging from the fastening plate 2122.

[0094] In some embodiments, as shown in FIG. 13, the dust bag support 2110 is provided with an elastic component 2115, for example, a spring. The elastic component 2115 is connected to the sliding baffle 2113, and is configured to make the sliding baffle 2113 to have a trend to be in the first position. The sliding baffle 2113 is in the first position under the action of the elastic component 2115 when the sliding baffle 2113 is not subjected to an external force, so that the sliding baffle 2113 shields the dust outlet port 2112. In some embodiments, the elastic component 2115 is located inside the dust bag support 2110, and an extension direction of the elastic component 2115 is basically the same as that of the socket 2114. The elastic component 2115 has one end fixed to an upper portion of the dust bag support 2110, and the other end connected to the sliding baffle 2113. The number of the elastic components 2115 may be one or more. When the number of the elastic components 2115 is two, for example, the two elastic components may be respectively arranged at two opposite ends of the dust bag support 2110.

[0095] The process of installment and removal of the dust bag 2120 and the dust bag support 2110 will be described in detail below.

[0096] When the dust bag support 2110 is not installed in the dust bag 2120, the sliding baffle 2113 on the dust bag support 2110 is in the first position, the dust outlet port 2112 is shielded, the sliding plate 2123 on the dust bag 2120 is in the closed position, and the fastening plate opening 21221 is shielded, just as shown in FIG. 8. In the process of installing the dust bag 2120 in the dust bag support 2110, the fastening plate 2122 and the sliding plate 2123 are inserted into the socket 2114 in the extension direction X of the socket 2114, and the sliding plate 2123 gradually moves from the closed position to the open position relative to the fastening plate 2122 when a user holds the handle portion 21232 of the sliding plate 2123 to push the dust bag 2120 into the socket 2114, such that the sliding plate opening 21231 on the sliding plate 2123 is aligned with the fastening plate opening 21221 on the fastening plate 2122. Meanwhile, the fastening plate 2122 and the sliding plate 2123 push the sliding baffle 2113 to move from the first position to the second position, so that the sliding baffle 2113 exposes the dust outlet port 2112. When the fastening plate 2122 slides to a snap-in position in the extension direction X of the socket 2114, the fastening plate opening 21221 interfaces with the dust outlet port 2112, and the fastening portion 21141 is cooperatively snapped with the fastening plate slot 21222, so that the dust bag 2120 is fixed to the dust bag support 2110. At this time, the flexible rubber ring 21224 on the dust bag passes through the sliding plate opening 21231 and abuts against an edge of the dust outlet port 2112, so that the fastening plate opening 21221 of the dust bag interfaces with the dust outlet port 2112 of the dust bag support in a sealing manner, so as to avoid leakage of the garbage during dust collection.

[0097] When the dust bag 2120 is withdrawn from the dust bag support 2110, the operator holds the handle portion 21232 of the sliding plate 2123 to gradually withdraw the sliding plate 2123 from the socket 2114 of the dust bag support 2110. In this process, the sliding plate 2123 gradually moves from the open position to the closed position relative to the fastening plate 2122, so that the sliding plate 2123 shields the fastening plate opening 21221. Moreover, the unlocking bump 21234 on the sliding plate 2123 squeezes the fastening portion 21141, so that the fastening portion 21141 disengages from the fastening plate slot 21222. Meanwhile, due to the interaction between the unlocking bump 21234 and the limiting component 21223 on the fastening plate 2122, the handle portion 21232 of the sliding plate 2123 can be continuously pulled to withdraw the sliding plate 2123 and the fastening plate 2122 from the socket 2114 of the dust bag support 2110. The dust bag 2120 disengages from the dust bag support 2110, and the sliding baffle 2113 returns to the first position under the action of the elastic component, so that the sliding baffle 2113 shields the dust outlet port 2112.

[0098] In some embodiments, the support side wall of the dust bag support facing the inside of the dust collection bin is provided with the dust outlet port configured to interface with the inlet of the dust bag.

[0103] In some embodiments, the dust bag further includes a sliding plate connected to the fastening plate in a slidable manner and configured to be switched between a third position and a fourth position, the sliding plate shields the fastening plate opening in response to the sliding plate being in the third position, and the sliding plate exposes the fastening plate opening in response to the sliding plate being in the fourth position.

[0104] In some embodiments, the sliding plate is provided with a sliding plate opening; in response to the sliding plate being in the third position, the sliding plate opening does not overlap with the fastening plate opening such that the sliding plate shields the fastening plate opening; and in response to the sliding plate being in the fourth position, the sliding plate opening substantially overlaps with the fastening plate opening such that the sliding plate exposes the fastening plate opening.

[0105] In some embodiments, the dust bag support includes a socket, and at least a part of the sliding baffle is located in the socket, so that the sliding baffle slides in an extension direction of the socket. The fastening plate and the sliding plate are configured to be insertable into the socket to slide in the extension direction of the socket; the sliding baffle is pushed to slide in the extension direction of the socket such that the dust bag is installed on the dust bag support; and in response to the dust bag being installed on the dust bag support, the sliding plate is in the fourth position to expose the fastening plate opening, and the sliding baffle is in the second position to expose the dust outlet port, so that the fastening plate opening interfaces with the dust outlet port.

[0106] In some embodiments, the dust bag support is provided with an elastic component, and the elastic component is connected to the sliding baffle and is configured to make the sliding baffle have a trend to be in the first position.

[0107] In some embodiments, the fastening plate is provided with a fastening plate slot, the socket is internally provided with a fastening portion, and the fastening portion is snapped in the fastening plate slot in response to the dust bag being installed on the dust bag support.
