[0032] To make the purpose, technical scheme and advantages of the present disclosure clearer and more apparent, the present disclosure is further explained in detail below in combination with drawings and embodiments. The specific embodiments described herein are only used to explain the present disclosure, and are not used to limit the present disclosure.

[0033] Referring to FIG. 1 to FIG. 7, an embodiment of the present disclosure provides an electric cleaning brush, including a housing 1 and a brush body 2. The brush body 2 includes a brush rod 21 and bristles. The bristles are connected to an outer periphery of the brush rod 21 and are used to clean a bottle. The brush rod 21 is provided with a liquid outlet channel 212, and a side surface or/and an end surface of the brush rod 21 is provided with a liquid outlet port 211. The liquid outlet port 211 is connected to the liquid outlet channel 212, and the liquid outlet channel 212 is connected to a cleaning bottle 5. The cleaning bottle 5 is used for storing cleaning liquid or other liquids.

[0034] In practical applications, the cleaning liquid in the cleaning bottle 5 is guided to the liquid outlet port 211 through the liquid outlet channel 212. In this way, the cleaning liquid can enter the bottle along with the brush rod 21. The brush rod 21 can be provided with the liquid outlet ports 211 at different positions, enabling the cleaning liquid to be sprayed towards different parts inside the bottle through the liquid outlet ports 211 at different positions. For example, by arranging the liquid outlet ports 211 on the end surface of the brush rod 21, the cleaning liquid can be sprayed to a bottom of the bottle through the liquid outlet ports 211 on the end surface. Alternatively, by arranging the liquid outlet ports 211 on the side surface of the brush rod 21, the cleaning liquid can be sprayed to the bottle body through the liquid outlet ports 211 on the side surface, facilitating multi-angle cleaning of the bottle 5 and improving cleaning efficiency.

[0035] Referring to FIG. 2 and FIG. 3, the electric cleaning brush further includes a driving component 3 and an adapter 4. The driving component 3 is configured to drive the brush body 2 to rotate, and includes a power device 31 and an output shaft 32. The output shaft 32 is provided with an axial channel 321. A first end of the output shaft 32 is fixedly connected to the brush rod 21, and a second end of the output shaft 32 is connected to the power device 31. The axial channel 321 is connected to the liquid outlet channel 212. The adapter 4 is fixedly arranged within the housing 1 and has a liquid storage chamber 43. The output shaft 32 is rotatably connected with the adapter 4, and is provided with a conductive segment 323 located inside the liquid storage chamber 43. The conductive segment 323 is provided with one or at least two lateral channels 322. The lateral channels 322 are connected to the axial channel 321 and the liquid storage chamber 43. The liquid storage chamber 43 is configured to connect to the cleaning bottle 5.

[0036] In one embodiment, one end of the output shaft 32 is connected to the brush rod 21, and the other end is connected to the power device 31 through the adapter 4. The power device 31 is used for driving the output shaft 32 to rotate, so that the output shaft 32 drives the brush rod 21 to rotate, and the function of automatically cleaning the bottle is realized. Meanwhile, the output shaft 32 is rotatably connected to the adapter 4. The adapter 4 has the liquid storage chamber 43, which is connected to the cleaning bottle 5. Therefore, the liquid in the cleaning bottle 5 can be easily guided into the liquid storage chamber 43. The liquid storage chamber 43 can be used for storing the liquid. The output shaft 32 is provided with the axial channel 321 and the lateral channels 322 which are connected to each other. The axial channels 321 are connected to the liquid outlet channel 212 of the brush rod 21. The lateral channels 322 are located inside the liquid storage chamber 43 and are connected to the liquid storage chamber 43, allowing the liquid in the liquid storage chamber 43 to be guided to the axial channel 321 through the lateral channels 322, and then guided to the liquid outlet channel 212 of the brush rod 21, and finally sprayed out from the liquid outlet 211. The effect that the cleaning liquid is guided out of the brush rod 21 is realized, and the cleaning liquid is prevented from being splashed out of the bottle and polluting the environment. Moreover, due to the rotational connection between the output shaft 32 and the adapter 4, the adapter 4 does not affect the rotation of output shaft 32, achieving the function of guiding the liquid while the output shaft 32 rotates. This allows for the simultaneous rotation of the brush rod 21 to clean the cleaning bottle 5 and spray cleaning solution into the cleaning bottle 5.

[0037] In an embodiment, the number of the lateral channels 322 can be set to one or more, and the lateral channels 322 can penetrate through the output shaft 32. In this way, the cleaning liquid in the liquid storage chamber 43 can enter the axial channel 321 from multiple openings, the flow of the liquid entering the axial channel 321 is increased, the time required for the cleaning liquid to be sprayed out is shortened, and the cleaning efficiency is improved.

[0038] It should be noted that the first end and the second end of the output shaft 32 refer to the opposite ends in the axial direction thereof.

[0039] Referring to FIG. 3 again, the adapter 4 is further provided with mounting channels 44 on two axial sides of the liquid storage chamber 43. The mounting channels 44 penetrate through the liquid storage chamber 43 along a axial direction. The output shaft 32 is rotatably connected to the mounting channels 44. An outer side of the conductive segment 323 is provided with a limiting protruding edge 324. The limiting protruding edge 324 abuts against junction between the liquid storage chamber 43 and the mounting channels 44.

[0040] In an embodiment, the limiting protruding edge 324 is connected to the conductive segment 323 of the output shaft 32, along the axial direction of the output shaft 32. The limiting protruding edge 324 abuts against the adapter 4., which on one hand limits an axial displacement of the output shaft 32 and increases a connection stability between the output shaft 32 and the power device 3. On the other hand, the limiting protruding edge 324 has a certain sealing property, which seals the liquid inside the storage chamber 43 and prevents the liquid from leaking out of the adapter 4.

[0041] In an embodiment, the limiting protruding edge 324 is arranged on opposite sides of the lateral channel 322 along the axial direction of the output shaft 32, which can effectively improve the sealing property of the connection between the lateral channel 322 and the liquid storage chamber 43.

[0042] Referring to FIG. 3 again, the mounting channel 44 is provided with an annular groove 45. The annular groove 45 is provided with a sealing ring, and the sealing ring is sleeved onto the output shaft 32. Specifically, the annular groove 45 can be arranged on the opposite sides of the liquid storage chamber 43 along the axial direction of the adapter 4. The sealing ring is arranged inside the annular groove 45, which can seal the liquid storage chamber 43, and further improves the sealing effect of the liquid storage chamber 43, preventing the liquid from seeping out to pollute an internal environment of the housing 1.

[0043] In an embodiment, the mounting channel 44 can be further provided with an abutting portion 42 in interference fit with an outer periphery of the output shaft 32. Specifically, along the axial direction of the adapter 4, the abutting portion 42 can be arranged on the opposite sides of the liquid storage chamber 43. The interference fit connection between the abutting portion 42 and the output shaft 32 can realize the sealing effect of the liquid storage chamber 43.

[0044] In an embodiment, the power device 31 can be an electric motor, and a rotating shaft of the electric motor is coaxially connected to the second end of the output shaft 32. In practical applications, the electric motor and the output shaft 32 can be symmetrically arranged about a central axis of the housing 1, ensuring that the output shaft 32 is located on the axis of the housing 1, so that when the output shaft 32 rotates, a force acting on the housing 1 in each direction is relatively uniform, thus avoiding uneven force distribution on the housing 1.

[0045] It should be noted that the rotating shaft of the electric motor can be directly connected to the output shaft or indirectly connected to the output shaft through an adapter, and the present disclosure does not limit this.

[0046] In an embodiment, the brush rod 21, the output shaft 32 and the electric motor can be coaxially arranged, so that the brush rod 21 rotates more timely, avoiding the delay effect of control and increasing the user experience.

[0047] Referring to FIG. 3 again, the electric cleaning brush includes a foamer 8, and the foamer 8 is arranged between the liquid outlet channel 212 and the output shaft 32.

[0048] In an embodiment, the foamer 8 is connected to the liquid outlet channel 212 and the axial channel 321 of the output shaft 32, respectively. When the cleaning liquid or other liquid is guided to the liquid outlet channel 212 through the axial channel 321, the liquid passes through the foamer 8, the foamer 8 mixes the liquid with air to generate abundant and delicate foam, and then the foam is guided to the liquid outlet hole through the liquid outlet channel 212. The liquid outlet hole guides the foam into the bottle. The foam can be better attached to the inner side of the bottle, increasing a contact area between the cleaning liquid and dirt, thus improving the cleaning effect.

[0049] Referring to FIG. 3 again, an assembly cavity 213 is provided at one end of the brush rod 21 that is close to the housing 1, the assembly cavity 213 is connected to the liquid outlet channel 212. The first end of the output shaft 32 extends outside the housing 1 and extends into the assembly cavity 213. The foamer 8 is arranged at the first end of the output shaft 32 and located in the assembly cavity 213, and connects to the axial channel 321 and the liquid outlet hole respectively.

[0050] In one embodiment, the assembly cavity 213 is further provided with a sealing member 30, a fixing bracket 40 and a sealing bottom plate 50. The foamer 8 is fixed on one end of the fixing bracket 40 close to the liquid outlet channel 212. The foamer 8 is connected to the axial channel 321 and the liquid outlet channel 212 respectively, so that the liquid can generate foam through the foamer 8 and be guided to the liquid outlet 211 through the liquid outlet channel 212. The fixing bracket 40 is fixed in the sealing member 30. The sealing member 30 is installed in the assembly cavity 213 and abuts against an inner wall of the assembly cavity 213 to realize the sealing effect and prevent the liquid from leaking out of the assembly cavity 213. An overall shape of the sealing member 30 is compatible with an inner cavity shape of assembly cavity 213, generally cylindrical, annular, or other shapes customized according to the shape of assembly cavity 213 to ensure a tight installation inside the assembly cavity 213. In some embodiments, the sealing member 30 can include sealing grooves and sealing ribs that cooperate with each other. The sealing groove is a concave groove, and the sealing rib is a protruding rib. When the sealing element 30 is installed in place, the sealing rib is embedded in the sealing groove, forming a labyrinth sealing structure, further improving the reliability of the seal. The sealing bottom plate 50 is arranged at an opening of the assembly cavity 213, which can not only fix the sealing element 30 inside the assembly cavity 213 to prevent it from falling off, but also improves the sealing performance of the assembly chamber 213. The foamer 8 is arranged in the brush rod 21, so that an accessory loss cost caused by the foamer 8 is reduced.

[0051] Referring to FIG. 4 and FIG. 5, the electric cleaning brush further includes a pump body 7 and a circuit component 20. The cleaning bottle 5 is connected to the liquid storage chamber 43 through the liquid inlet tube 6. The pump body 7 is connected to the cleaning bottle 5 or the liquid inlet tube 6. The circuit component 20 is connected to the driving component 3 and the pump body 7 respectively. In practical applications, the pump body 7 is mainly used to provide power for the liquid, so that the liquid can be pumped out of the cleaning bottle 5 and guided to the liquid storage chamber 43, and then guided from the liquid storage chamber 43 to the axial channel 321 and the liquid outlet channel 212, and finally sprayed into the bottle from the liquid outlet 211. The circuit component 20 mainly provides electrical energy for the pump body 7 and the driving component 3. The circuit component 20 is provided with a plurality of function buttons for controlling the pump body 7 and the driving component 3 to start or stop. When the user presses or touches the function buttons, the pump body 7 or the driving component 3 starts or stops working.

[0052] In one embodiment, referring to FIG. 4, the pump body 7 and the driving component 3 are sequentially arranged along an axial direction of the housing 1, and the pump body 7 and a circuit component are sequentially arranged along a radial direction of the housing 1. By setting along the axial and radial directions of the housing 1, an overall weight of the housing 1 will be relatively uniform, avoiding a situation of heavy weight on one side, and an internal layout will be more balanced, improving the comfort of users when holding the housing 1. The pump body 7 and the circuit components 20 are positioned on left and right sides respectively along the axial direction of the housing 1. By achieving a more uniform mass distribution, a center of gravity of the electric cleaning brush is aligned with the geometric center or brought close to a gripping point, thereby reducing the impact of eccentric moments on stability.

[0053] Referring to FIG. 3, the electric cleaning brush further includes a fixing component 9 connected inside the housing 1. The adapter 4, the power device 31, the pump body 7 and the circuit component 20 are all connected to the fixing component 9. The pump body 7 and the driving component 3 are sequentially arranged along an axial direction of the fixing component 9, and the pump body 7 and the circuit component are sequentially arranged along a radial direction of the fixing component 9. In this way, multiple components are all mounted on the fixing component 9, so that the structure is more compact, a mounting space inside the housing 1 is saved, an assembly efficiency of the device is improved, and a structural integration is improved.

[0054] Referring to FIG. 3 again, the fixing component 9 includes a fixing frame 92 and a fixing cover 91. The fixing frame 92 is connected to the housing 1. The power device 31, the pump body 7 and the circuit component 20 are all connected to the fixing frame 92, and the adapter 4 is connected to the fixing cover 91. The fixing cover 91 is provided with a first clamping portion 911, the fixing frame 92 is provided with a second clamping portion 921, and the first clamping portion 911 is clamped with the second clamping portion 921.

[0055] In an embodiment, the adapter 4 is connected to the fixing cover 91, and then the fixing cover 91 is connected to the fixing frame 92 through a clamping action of the first clamping portion 911 and the second clamping portion 921, thereby completing the mounting of the adapter 4. Through the clamping mode, the fixing cover 91 and the fixing frame 92 are mounted and dismounted more simply. The fixing frame 92 serves as a primary mounting component for mounting the power device 31, the pump body 7 and the circuit component 20. The power device 31, the pump body 7 and the circuit component 20 are connected to the fixing frame 92 in a detachable manner for easy maintenance and replacement.

[0056] In an embodiment, referring to FIG. 6, the fixing component 9 is further provided with a third clamping portion 922 outside, the housing 1 is provided with a fourth clamping portion 11 inside, and the third clamping portion 922 is clamped with the fourth clamping portion 11.

[0057] Specifically, the second clamping portion 921 is provided at one end of the fixing frame 92 close to the fixing cover 91, for clamping with the first clamping portion 911 of the fixing cover 91. The third clamping portion 922 is provided at one end away from the fixing cover 91, for clamping with the fourth clamping portion 11 inside the housing 1, to realize a fixed connection between the fixing frame 92 and the housing 1, thereby completing the assembly of the fixing frame 92. In this way, the multiple components can be mounted and fixed by clamping the fixing frame 92 with the housing 1, making assembly simpler.

[0058] Referring to FIG. 6 again, the electric cleaning brush further includes a bottom cover 10, which is arranged at a bottom of the housing 1. A fifth clamping portion 923 is provided at one side of the fixing frame 92 near the bottom of the housing 1, and a sixth clamping portion 102 is provided at one end near the fixing frame 92. By clamping the fifth clamping portion 923 with the sixth clamping portion 102, a fixed connection between the bottom cover 10 and the fixing frame 92 can be achieved. By connecting the fixing frame 92 to the housing 1, the bottom cover 10 is connected to the housing 1, and the assembly of the bottom cover 10 is completed.

[0059] Meanwhile, a bottom of the bottom cover 10 is provided with a first connecting portion 101. A bottle opening of the cleaning bottle 5 is provided with a second connecting portion 51. The first connecting portion 101 is detachably connected to the second connecting portion 51. The liquid inlet tube 6 is connected to the bottom cover 10 and is connected to the cleaning bottle 5, for easy discharge of the liquid from the cleaning bottle 5.

[0060] In one embodiment, the first connecting portion 101 and the second connecting portion 51 are detachably connected, so that the cleaning bottle 5 can be removed easily, and the liquid in the cleaning bottle 5 can be added or replaced. The first connecting portion 101 and the second connecting portion 51 can be threaded together. The cleaning bottle 5 and the bottom cover 10 are fixed by thread connection. The first connecting portion 101 and the second connecting portion 51 can also be connected by other connection methods such as clamped or buckle. The present disclosure is not limited.

[0061] Referring to FIG. 2 again, a bottom of the cleaning bottle 5 is provided with an air inlet valve 52. The air inlet valve 52 is used to balance the air pressure inside and outside the cleaning bottle 5. When the cleaning liquid is squeezed out of the cleaning bottle 5, the pressure inside the cleaning bottle 5 gradually decreases. As the liquid flows out, negative pressure is formed inside the cleaning bottle 5, which makes it difficult or even impossible for the liquid to flow out. The presence of the air inlet valve 52 allows external air to enter the cleaning bottle 5 while the liquid flows out, balancing the pressure inside the cleaning bottle 5, and ensuring that the cleaning liquid can flow out smoothly and continuously.

[0062] It should be noted that the air inlet valve 52 is not limited to being arranged at the bottom of the cleaning bottle 5, and can also be in any other position, such as a side wall of the cleaning bottle 5. The air inlet valve 52 can be of any shape, such as circular or square.

[0063] In some other embodiments, in addition to the air inlet valve 52 for balancing the air pressure inside and outside the bottle, other methods can also be adopted. The present disclosure is not limited.

[0064] Different from the prior art, the embodiments of the present disclosure provide the electric cleaning brush, including the housing 1, the brush body 2, the driving component 3 and the adapter 4. The brush body 2 includes the brush rod 21, which is provided with the connected liquid outlet channel 212 and the liquid outlet 211. The driving component 3 includes the power device 31 and the output shaft 32. The output shaft 32 is provided with the axial channel 321, the first end of the output shaft 32 is fixedly connected to the brush rod 21, the second end of the output shaft 32 is connected to the power device 31, and the axial channel 321 is connected the liquid outlet channel 212. The adapter 4 is fixedly arranged in the housing 1 and has the liquid storage chamber 43. The output shaft 32 is rotatably connected to the adapter 4, and has the conductive segment 323 located inside the liquid storage chamber 43. The conductive segment 323 is provided with one or at least two lateral channels 322, which are connected to the axial channel 321 and the liquid storage chamber 43. The liquid storage chamber 43 is configured to connect the cleaning bottle 5. Compared with the prior art, one end of the output shaft 32 in the present disclosure is connected to the brush rod 21, and the other end is connected to the power device 31 through the adapter 4. The power device 31 is used for driving the output shaft 32 to rotate, so that the output shaft 32 drives the brush rod 21 to rotate, and the function of automatically cleaning the bottle is realized. The adapter 4 has the liquid storage chamber 43, which is connected to the cleaning bottle 5. Therefore, the liquid in the cleaning bottle 5 can be easily guided into the liquid storage chamber 43. The lateral channels 322 are located inside the liquid storage chamber 43 and are connected to the liquid storage chamber 43, allowing the liquid in the liquid storage chamber 43 to be guided to the axial channel 321 through the lateral channels 322, and then guided to the liquid outlet channel 212 of the brush rod 21, and finally sprayed out from the liquid outlet 211. The effect that the cleaning liquid is guided out of the brush rod 21 is realized, and the cleaning liquid is prevented from being splashed out of the bottle and polluting the environment. Moreover, due to the rotational connection between the output shaft 32 and the adapter 4, the adapter 4 does not affect the rotation of output shaft 32, achieving the function of guiding the liquid while the output shaft 32 rotates. This allows for the simultaneous rotation of the brush rod 21 to clean the cleaning bottle 5 and spray cleaning solution into the cleaning bottle 5. By rotating the output shaft 32 to generate centrifugal force, this centrifugal force is utilized to make the cleaning liquid that enters the axial channel from the storage chamber via the lateral channels flow steadily and directionally along the axial channel, and be precisely delivered to the outlet channel of the brush rod and then sprayed out from the outlet port, thus preventing the cleaning liquid from splashing randomly.

[0065] The above are only specific embodiments of the present disclosure. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present disclosure, and these improvements and modifications should also be considered within the scope of protection of the present disclosure.
