DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will describe the present disclosure with reference to the accompanying drawings in further detail. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts should fall within the protection scope of the present disclosure.

[0037] It should also be noted that, the terms comprise, include, or any other variants thereof are intended to cover the nonexclusive inclusion, such that a commodity or apparatus including a series of elements includes not only those elements, but also other elements not listed explicitly or elements inherent to such a commodity or apparatus. Without more limitations, the element defined by the phrase including a does not exclude the existence of other same elements in the commodity or apparatus including the element.

[0038] In the art, vacuum cleaners and various types of cleaning devices involving a dust suction function usually include fans for providing power for a dust suction operation and dust collecting buckets for collecting debris.

[0039] In some related arts, during use of the vacuum cleaner, a dust-collection main unit is usually detached from a dust collecting bucket to clean up the debris in the dust collecting bucket. During cleanup of the debris in the dust collecting bucket, a cyclone drum and/or a filter assembly in the dust collecting bucket will be usually detached from the dust collecting bucket to facilitate cleanup of the debris in the dust collecting bucket. After the cleanup is completed, a user may inadvertently omit the installation of the cyclone drum and/or the filter assembly and directly installs a dust suction assembly on the dust collecting bucket, which possibly causes operational failure and negatively affects the product performance and life.

[0040] The present disclosure provides a vacuum cleaner, including: a dust-collection main unit configured to provide power for a dust suction operation; a dust collecting bucket configured to be detachably installed with the dust-collection main unit, and configured to collect debris under the action of the dust-collection main unit; and a foolproof assembly arranged on the dust collecting bucket and configured to be switched between a normal working position and an abnormal working position. When the foolproof assembly is in the normal working position, the dust-collection main unit is allowed to be assembled to the dust collecting bucket, and when the foolproof assembly is in the abnormal working position, the dust-collection main unit is prevented from being assembled to the dust collecting bucket.

[0041] According to the embodiments of the present disclosure, by arranging the foolproof assembly on the dust collecting bucket of the vacuum cleaner, the foolproof assembly cooperates with a cyclone drum and/or a filter assembly installed in the dust collecting bucket, so that the dust-collection main unit can be assembled to the dust collecting bucket only after the cyclone drum and/or the filter assembly are/is correctly installed on the dust collecting bucket, thereby avoiding an abnormal operation of the vacuum cleaner caused by the fact the user neglects to install the cyclone drum and/or the filter assembly. According to the present disclosure, by arranging the mechanical foolproof assembly on the dust collecting bucket, a simple structure without a control circuit is achieved, so that the reliability is improved while the cost is reduced.

[0042] Optional embodiments of the present disclosure will be described in detail below in combination with the accompanying drawings.

[0043] FIG. 1 is a schematic structural diagram of a vacuum cleaner according to some embodiments of the present disclosure. Referring to FIG. 1, some embodiments of the present disclosure provide a vacuum cleaner 10, and the vacuum cleaner 10 includes a dust collecting bucket 100, a dust-collection main unit 200, and a foolproof assembly. The dust collecting bucket 100 is detachably installed with the dust-collection main unit 200, and the dust-collection main unit 200 is used for providing power for a dust suction operation. The dust collecting bucket 100 is used for collecting debris under the action of the power provided by the dust-collection main unit 200. The foolproof assembly is arranged on the dust collecting bucket 100 and configured to be switched between a normal working position and an abnormal working position. When the foolproof assembly is in the normal working position, the dust-collection main unit is allowed to be assembled to the dust collecting bucket, and when the foolproof assembly is in the abnormal working position, the dust-collection main unit is prevented from being assembled to the dust collecting bucket. Therefore, the abnormal operation of the vacuum cleaner caused by the fact that the user neglects to install assemblies, such as a cyclone drum and/or a filter assembly, in the dust collecting bucket can be avoided. The foolproof assembly includes a first foolproof assembly and a second foolproof assembly, which will be introduced later.

[0044] FIG. 2 is a schematic structural diagram of a dust collecting bucket according to some embodiments of the present disclosure. As shown in the figure, the cyclone drum is arranged in the dust collecting bucket, and the filter assembly is not assembled. Referring to FIG. 2, the dust collecting bucket 100 further includes: a dust collecting bucket body 110, a cyclone drum 120, and a first foolproof member 130. The cyclone drum 120 is detachably installed in the dust collecting bucket body 110, and an outer diameter of the cyclone drum 120 is slightly smaller than an inner diameter of the dust collecting bucket body 110, so that the cyclone drum 120 can be nested in the dust collecting bucket body 110.

[0045] FIG. 3 is a schematic structural diagram of the dust collecting bucket when the first foolproof member is in a first working position according to some embodiments of the present disclosure; FIG. 4 is a schematic structural diagram of the dust collecting bucket when the first foolproof member is in a second working position according to some embodiments of the present disclosure; and FIG. 5 is a schematic structural diagram of a cyclone drum according to some embodiments of the present disclosure. Referring to FIG. 2 to FIG. 5, in some embodiments, the first foolproof member 130 is arranged on the inner side wall of the dust collecting bucket 100, and specifically arranged on the inner wall of the side, facing the dust-collection main unit 200, of the dust collecting bucket 100.

[0046] The first foolproof member 130 is used for restricting the assembly of the dust collecting bucket 100 and the dust-collection main unit 200, so as to avoid a wrong assembly state caused by omission of installation of the cyclone drum 120 in the dust collecting bucket 100. Specifically, the first foolproof member 130 may be switched between the first working position and the second working position, the first working position belongs to a normal working position and the second working position belongs to an abnormal working position. When the first foolproof member 130 is in the first working position, the dust-collection main unit 200 is assembled to the dust collecting bucket body 110, and when the first foolproof member 130 is in the second working position, the dust-collection main unit 200 cannot be assembled to the dust collecting bucket body 110.

[0047] In some embodiments, the first foolproof member 130 is used in cooperation with the cyclone drum 120, so that when the cyclone drum 120 is installed in the dust collecting bucket body 110, the first foolproof member 130 is switched from the second working position to the first working position. At this time, the dust-collection main unit 200 can be assembled to the dust collecting bucket body 110; when the cyclone drum 120 is detached from and removed from the dust collecting bucket body 110, the first foolproof member 130 is switched from the first working position to the second working position. At this time, the dust-collection main unit 200 cannot be assembled to the dust collecting bucket body 110.

[0048] Through coordinative cooperation of the first foolproof member 130 and the cyclone drum 120, the dust-collection main unit 200 can be assembled to the dust collecting bucket body 110 only after the cyclone drum 120 is correctly installed in the dust collecting bucket body 110, thereby avoiding the abnormal operation of the vacuum cleaner 10 caused by the fact that the user neglects to install the cyclone drum 120.

[0049] In some embodiments, the coordinative cooperation of the first foolproof member 130 and the cyclone drum 120 is achieved through spring compression.

[0050] Specifically, a first elastic member 140 is arranged on the inner side wall of the dust collecting bucket body 110, and the first elastic member 140 can bias the first foolproof member 130 toward the second working position. That is, when the first foolproof member 130 is subjected to an elastic force provided by the first elastic member 140, the first foolproof member 130 exhibits a tendency to move towards the second working position, and when the first foolproof member 130 is only subjected to the elastic force provided by the first elastic member 140 without other external forces, the first foolproof member 130 is in the second working position. In some embodiments, the first elastic member 140 is a torsion spring.

[0051] In some embodiments, the first foolproof member 130 further includes a first arm 131, a second arm 132, and a first rotating shaft 133. The first foolproof member 130 may pivot along the first rotating shaft 133 in a plane parallel to an axis A of the dust collecting bucket 100 to be switched between the first working position and the second position. A predetermined included angle is formed between the first arm 131 and the second arm 132, and the included angle may range from, for example, 15 degrees to 175 degrees.

[0052] The cyclone drum 120 includes an abutting part 121 and a notch 122 adjacent to the abutting part 121. In the process of installing the cyclone drum 120 in the dust collecting bucket body 110, the abutting part 121 presses against the first arm 131, and a contact point between the abutting part 121 and the first arm 131 moves from a free end 1311 of the first arm 131 towards the second arm 132, so that the second arm 132 is accommodated in the notch 122, and further the first foolproof member 130 is switched from the second working position to the first working position.

[0053] FIG. 6 is a structural schematic diagram of a filter assembly according to some embodiments of the present disclosure; FIG. 7 is a schematic structural diagram of a dust collecting bucket equipped with a filter assembly according to some embodiments of the present disclosure; FIG. 8 is a partial enlarged schematic diagram of a section of FIG. 2; and FIG. 9 is a schematic structural diagram of a dust-collection main unit according to some embodiments of the present disclosure.

[0054] Referring to FIG. 6 to FIG. 9, in some embodiments, the vacuum cleaner 10 further includes a filter assembly 300 detachably installed in the cyclone drum 120. In some embodiments, the cyclone drum 120 includes an installation groove for accommodating the filter assembly 300. Specifically, an accommodating space for accommodating the filter assembly 300 is formed in the installation groove, and the filter assembly 300 is nested in the accommodating space of the installation groove.

[0055] In some embodiments, the dust collecting bucket 100 further includes a second foolproof member 150. As an example, the second foolproof member 150 is arranged on the inner side wall of the cyclone drum 120, and specifically arranged on the inner wall of the side, facing the dust-collection main unit 200, of the cyclone drum 120.

[0056] The second foolproof member 150 is used for restricting the assembly of the dust collecting bucket 100 and the dust-collection main unit 200, so as to avoid a wrong assembly state caused by omission of installation of the filter assembly 300 in the dust collecting bucket 100. Specifically, referring to FIG. 8, the second foolproof member 150 may be switched between a third working position and a fourth working position, the third working position belongs to a normal working position and the fourth working position belongs to an abnormal working position. When the second foolproof member 150 is in the third working position, the dust-collection main unit 200 is assembled to the dust collecting bucket body 110 equipped with the cyclone drum 120, and when the second foolproof member 150 is in the fourth working position, the dust-collection main unit 200 cannot be assembled to the dust collecting bucket body 110 equipped with the cyclone drum 120.

[0057] In some embodiments, the second foolproof member 150 is used in cooperation with the filter assembly 300, so that when the filter assembly 300 is installed in the cyclone drum 120, the second foolproof member 150 is switched from the fourth working position to the third working position. At this time, the dust-collection main unit 200 can be assembled to the dust collecting bucket body 110. When the filter assembly 300 is removed from the cyclone drum 120, the second foolproof member 150 is switched from the third working position to the fourth working position. At this time, the dust-collection main unit 200 cannot be assembled to the dust collecting bucket body 110.

[0058] Through coordinative cooperation between the second foolproof member 150 and the filter assembly 300, the dust-collection main unit 200 can be assembled to the dust collecting bucket body 110 only after the filter assembly 300 is correctly installed in the cyclone drum 120, thereby avoiding the abnormal operation of the vacuum cleaner 10 caused by the fact that the user neglects to install the filter assembly 300.

[0059] In some embodiments, the coordinative cooperation between the second foolproof member 150 and the filter assembly 300 is achieved through spring compression.

[0060] Specifically, a second elastic member is arranged on the inner side wall of the cyclone drum 120, and the second elastic member can bias the second foolproof member 150 toward the fourth working position. That is, when the second foolproof member 150 is subjected to an elastic force provided by the second elastic member, the second foolproof member 150 exhibits a tendency move towards the fourth working position, and when the second foolproof member 150 is only subjected to the elastic force provided by the second elastic member without other external forces, the second foolproof member 150 is in the fourth working position. In some embodiments, the second elastic member is a torsion spring.

[0061] Referring to FIG. 6, the filter assembly 300 includes a pressing member 310, and the pressing member 310 is used in cooperation with the second foolproof member 150 to restrict the assembly of the dust-collection main unit 200. When the filter assembly 300 is installed in the cyclone drum 120, the pressing member 310 presses against the second foolproof member 150, so that the second foolproof member 150 is switched from the fourth working position to the third working position. Specifically, after the filter assembly 300 is installed in the cyclone drum 120, the pressing member 310 can exert a pressing force on the second foolproof member 150, and the pressing force can at least partially offset the elastic force exerted by the second elastic member on the second foolproof member 150, so that the second foolproof member 150 cannot move to the fourth working position.

[0062] When the filter assembly 300 is removed from the cyclone drum 120, the second foolproof member 150 is switched from the third working position to the fourth working position. Specifically, after the filter assembly 300 is removed from the cyclone drum 120, the pressing member 310 no longer exerts the pressing force on the second foolproof member 150, so that the second foolproof member 150 moves to the fourth working position.

[0063] Referring to FIG. 5, in some embodiments, a groove 123 is arranged in an end part, close to the top surface of the cyclone drum 120, of the inner side wall of the cyclone drum 120, and the groove 123 is used for accommodating the second foolproof member 150. The second foolproof member includes a columnar body 151 extending in an axial direction B of the cyclone drum 120, and the top surface of the columnar body 151 is farther away from the bottom of the groove 123 relative to the top surface of the cyclone drum 120.

[0064] Referring to FIG. 9, in some embodiments, the top surface, facing the dust collecting bucket 100, of the dust-collection main unit 200 is provided with a clamping groove 210. When the second foolproof member 150 is in the third working position and the dust-collection main unit 200 is assembled to the dust collecting bucket body 110, the columnar body 151 is just aligned with the clamping groove 210, and at least part of the columnar body 151 is inserted into the clamping groove 210. When the second foolproof member 150 is in the fourth working position, the columnar body 151 cannot be aligned with the clamping groove 210, so that the dust-collection main unit 200 cannot be correctly assembled to the dust collecting bucket body 110.

[0065] Referring to FIG. 5 and FIG. 8, the second foolproof member 150 may pivot along a second rotating shaft 152 in a plane perpendicular to an axis B of the cyclone drum 120. When the second foolproof member 150 is in the third working position, a free end 153 of the second foolproof member 150 is accommodated in the groove 123 in the plane perpendicular to the axis B of the cyclone drum 120. When the second foolproof member 150 is in the fourth working position, the free end 153 of the second foolproof member 150 is away from the groove 123 in the plane perpendicular to the axis B of the cyclone drum 120.

[0066] According to the embodiments of the present disclosure, by arranging the second foolproof member on the cyclone drum and the cooperation of the second foolproof member with the filter assembly and the clamping groove on the dust-collection main unit, the dust-collection main unit can be assembled to the dust collecting bucket only after the filter assembly is correctly installed to the dust collecting bucket equipped with the cyclone drum, thereby avoiding the abnormal operation of the vacuum cleaner caused by the fact that dust in the dust collecting bucket enters the dust-collection main unit since the user neglects to install the filter assembly. According to the present disclosure, by arranging the mechanical foolproof members on the dust collecting bucket, a control circuit is not needed, so that the reliability is improved while the cost is reduced.

[0067] Finally, it should be noted that various embodiments in the Description are described in a progressive manner, each embodiment focuses on the differences from other embodiments, and the same or similar parts among the various embodiments may refer to one another. For the system or the apparatus disclosed in the embodiments, since the system or the apparatus corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts may refer to the description of the method part.
