[0036] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

[0037] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0038] In order to better understand the base station 2 provided in this application, the cleaning device 100 is first described.

[0039] The present application discloses a cleaning device 100. Figures 1 to 4 , including a floor brush 1 and a base station 2 in any one of the following embodiments.

[0040] The cleaning device 100 may be a floor scrubber, a washer-mop machine, or a washer-dryer-dryer.

[0041] The base station 2 can provide a placement location for the floor brush 1, charge the floor brush 1, rinse the floor brush 1, dry the floor brush 1, collect dust, and cut hair.

[0042] Another aspect of the present application embodiment discloses a base station 2. Figures 1 to 8 The base station 2 includes a housing 21, a cutting member 22, and a cover 23. The housing 21 is formed with a guide groove 21a, and the floor brush 1 is movably arranged in the guide groove 21a. The cutting member 22 is arranged in the guide groove 21a and is used to cut foreign matter on the floor brush 1. The cover 23 is configured to shield or avoid the cutting member 22. The floor brush 1 is configured to slide along the guide direction of the guide groove 21a and push the cover 23 to avoid the cutting member 22, so that the floor brush 1 contacts the cutting member 22.

[0043] For example, the foreign matter may be hair, pet hair, etc.

[0044] The base station 2 provided by the present application has a guide groove 21a formed in the shell 21, and the cutting piece 22 is arranged in the guide groove 21a for cutting the hair on the floor. The cover 23 is configured to cover or avoid the cutting piece 22, and the floor brush 1 can move along the guide direction of the guide groove 21a. When the floor brush 1 moves and contacts the cover 23, the cover 23 can be pushed to avoid the cutting piece 22. In this way, when the floor brush 1 is placed in the guide groove 21a, the floor brush 1 can be cut by the movement of the floor brush 1 itself or the force applied to the floor brush 1 by the user. , so that the floor brush 1 can move along the guide direction of the guide groove 21a and push the cover 23 to avoid the cutting piece 22, so that the cutting piece 22 contacts the floor brush 1. When foreign matter needs to be cleaned, the cutting piece 22 can cut the foreign matter on the floor brush 1 to reduce the jamming of the floor brush 1 during subsequent cleaning. By moving the floor brush 1 and pushing the cover 23 to avoid the cutting piece 22, there is no need to set a controller for controlling the cover 23 and electrical components such as a motor. The structure is relatively simple and the manufacturing cost is low.

[0045] The cleaning device 100 provided in the present application, based on the advantages of the above-mentioned base station 2, has a simpler structure and lower manufacturing cost.

[0046] It should be noted that avoiding means that the cover 23 does not cover the cutting piece 22 , so that the floor brush 1 can come into contact with the cutting piece 22 .

[0047] Exemplarily, in one embodiment, the up and down direction may be the height direction of the base station 2 .

[0048] It should be noted that up can point to the direction of the ceiling, and down is the opposite of up.

[0049] For example, in one embodiment, Figure 1R1 can be the up and down direction, R2 can be the guide direction, and R3 can be the axial direction of the rotation axis.

[0050] In one embodiment, please refer to Figure 2 、 Figure 6 and Figure 7 The guide groove 21a includes a sliding groove 21a1 and a cutting groove 21a2 that are interconnected. The cutting piece 22 is arranged in the cutting groove 21a2. The cover body 23 can selectively cover the cutting groove 21a2 to shield the cutting piece 22 or open the cutting groove 21a2 to avoid the cutting piece 22. The floor brush 1 is configured to be able to slide in the sliding groove 21a1 and the cutting groove 21a2. When the floor brush 1 slides to the cutting groove 21a2, the floor brush 1 pushes the cover body 23 to open the cutting groove 21a2.

[0051] Here, the guide groove 21a is divided into a sliding groove 21a1 and a cutting groove 21a2. The cutting groove 21a2 is used to set the cutting piece 22. The floor brush 1 can slide in both the sliding groove 21a1 and the cutting groove 21a2. When placing the floor brush 1, since the cutting groove 21a2 is blocked by the cover body 23, the floor brush 1 can be put in from the sliding groove 21a1. When the floor brush 1 slides to the cutting groove 21a2, the floor brush 1 can push the cover body 23 to open the cutting groove 21a2 to avoid the cutting piece 22, so that the floor brush 1 can contact the cutting piece 22 located in the cutting groove 21a2, and can cut foreign matter.

[0052] In one embodiment, please refer to Figures 1 to 7 The bottom surface of the guide groove 21a is tilted downward along the guide direction, and the cutting piece 22 is arranged at a relatively low end in the guide groove 21a, and the guide direction intersects the up and down direction.

[0053] Illustratively, any part of the bottom surface of the cutting groove 21a2 is lower than the bottom surface of the guide groove 21a in the up-down direction, so as to form a slope-like shape.

[0054] Here, the bottom surface of the guide groove 21a is tilted downward along the guide direction, and the cutting piece 22 is arranged at a relatively low end in the guide groove 21a. In this way, when the floor brush 1 is placed in the guide groove 21a, the floor brush 1 can use its own gravity to move along the guide direction of the guide groove 21a to the relatively low end. In this way, the cover body 23 can be automatically pushed to avoid the cutting piece 22. In this process, the user does not need to add additional actions, the overall operation is convenient, and no additional electrical components are required, and the overall cost is low.

[0055] Exemplarily, in one embodiment, the bottom surface of the guide groove 21a can also be set horizontally. In this way, after placing the floor brush 1 in the sliding groove 21a1, the user can manually push the floor brush 1 to the cutting groove 21a2 and push the flip cover to avoid the cutting piece 22, so that the floor brush 1 can contact the cutting piece 22 for subsequent foreign body cutting work.

[0056] In one embodiment, please refer to Figures 1 to 4 The cover 23 has a first state and a second state. In the first state, the floor brush 1 pushes the cover 23 to avoid the cutting piece 22. In the second state, the floor brush 1 is separated from the cover 23, and the cover 23 covers the cutting piece 22.

[0057] That is to say, in the first state, the floor brush 1 can be placed in the guide groove 21a and the cover 23 can be pushed to avoid opening the cutting piece 22, so that the floor brush 1 contacts the cutting section to cut foreign objects; in the second state, the floor brush 1 can be removed from the guide groove 21a to separate the floor brush 1 from the cover 23. At this time, the cover 23 will cover the cutting piece 22, which can reduce the occurrence of foreign objects such as stones, metals, etc. falling on the cutting piece 22 and affecting its function, and the degree of automation is relatively high.

[0058] In one embodiment, please refer to Figures 1 to 6 The cover 23 is rotatably connected to the housing 21, and the cover 23 is rotated and switched between the first state and the second state by pushing and pulling the floor brush 1.

[0059] Here, when it is necessary to clean foreign matter on the floor brush 1, the floor brush 1 can be placed in the guide groove 21a, and then the cover body 23 can be pushed by the floor brush 1 to rotate, so that the cover body 23 rotates to avoid the cutting piece 22, so that the cutting piece 22 can come into contact with the floor brush 1 to carry out the subsequent cutting of foreign matter; when it is necessary to remove the floor brush 1 for floor cleaning, the floor brush 1 can be pulled out of the guide groove 21a. At this time, the cover body 23 can be rotated in the opposite direction to cover the cutting piece 22 because there is no obstruction of the floor brush 1. In this way, the damage caused by the exposure of the cutting piece 22 can be reduced. Here, the housing 21 is rotatably connected to the cover body 23. The user only needs to use an appropriate amount of force to push or pull the floor brush 1 so that the cover body 23 rotates to avoid or rotate to cover the cutting piece 22. No complicated steps and tools are required, and it is easy to implement.

[0060] Exemplarily, in one embodiment, the cover 23 is retractably arranged in the shell 21, so that the cover 23 can be pushed back into the shell 21 by the floor brush 1 to avoid opening the cutting piece 22. When the floor brush 1 needs to be removed for cleaning, the cover 23 can be extended out of the shell 21 to cover the cutting piece 22. The whole process is similar to the opening and closing method of a drawer.

[0061] Exemplarily, in one embodiment, in the first state, the angle at which the floor brush 1 pushes the cover body 23 to rotate and open can be less than 90°, for example, about 30°. In this way, in the second state, since the cover body 23 is separated from the floor brush 1, the cover body 23 is not blocked by the floor brush 1. At this time, the cover body 23 can rotate by relying on its own gravity to cover the cutting piece 22.

[0062] In one embodiment, please refer to Figures 6 to 8 The base station 2 includes an elastic member 24, and the cover 23 includes a cover plate 231 and a support arm 232. The cover plate 231 is used to shield or avoid the cutting member 22. One end of the support arm 232 is connected to the cover plate 231, and the other end of the support arm 232 is rotatably connected to the housing 21. The elastic member 24 is disposed between the support arm 232 and the housing 21. In a first state, the elastic member 24 stores elastic potential energy. In a second state, the elastic member 24 recovers its deformation to push the cover 23 to shield the cutting member 22.

[0063] Here, by connecting one end of the support arm 232 to the cover body 23, and the other end of the support arm 232 to the shell 21 for rotation, the elastic member 24 is arranged between the support arm 232 and the shell 21. In this way, when it is necessary to clean foreign matter on the floor brush 1, the floor brush 1 can be pushed to rotate along the guide direction of the guide groove 21a, so that the cover body 23 avoids the cutting member 22. At this time, the floor brush 1 can contact the cutting member 22 to perform subsequent foreign matter cutting work. Since the cover body 23 and the shell 21 rotate relative to each other at this time, the elastic member 24 located between the shell 21 and the support arm 232 will deform and store elastic potential energy; when it is necessary to remove the floor brush 1 to clean the floor, the floor brush 1 can be pulled out of the guide groove 21a. At this time, since the cover body 23 is not blocked by the floor brush 1, the elastic member 24 can restore the deformation and convert the elastic potential energy into thrust to push the cover body 23 to reset and rotate, covering the cutting member 22.

[0064] In this way, by setting the elastic member 24, the floor brush 1 can have a certain critical force when pushing the cover body 23 to avoid the cutting member 22. In this way, the accidental opening of the cover body 23 can be reduced. When the floor brush 1 is removed, the elastic member 24 can give the cover body 23 a certain thrust, so that it can push the cover body 23 to return to its original position to cover the cutting member 22. This makes the operation of covering and avoiding the cutting member 22 with the cover body 23 simpler and easier to implement.

[0065] For example, in one embodiment, please refer to Figures 6 to 8The number of support arms 232 and elastic members 24 can be two each. The two support arms 232 are spaced apart on both sides of the cover body 23 along the axial direction of the rotation axis of the cover body 23, and each elastic member 24 is arranged between the corresponding support arm 232 and the shell 21. In this way, the accidental opening can be further reduced, and the working stability of the cover body 23 when rotating can be improved.

[0066] Exemplarily, the axial direction of the rotation axis of the cover body 23 may be the left-right direction of the base station 2 .

[0067] In one embodiment, please refer to Figure 6 and Figure 7 The shell 21 is formed with an installation cavity 21b and an avoidance opening 21c communicating with the installation cavity 21b, the avoidance opening 21c extends along the guide direction, the installation cavity 21b is provided with a fixing seat 22b1, and part of the support arm 232 is rotatably connected to the fixing seat 22b1 through the avoidance opening 21c.

[0068] For example, the mounting cavity 21b may be provided with a cutout 21a2 on a side away from the sliding groove 21a1 along the guide direction. The escape opening 21c extends along the guide direction, thereby providing clearance for the rotation of the support arm 232 and avoiding structural interference. The fixing seat 22b1 may be fixed to the bottom surface of the housing 21 by screws or bolts.

[0069] Here, by forming the installation cavity 21b and the avoidance opening 21c, part of the support arm 232 can be located in the installation cavity 21b through the avoidance opening 21c and rotatably connected to the fixed seat 22b1. In this way, the connection part between the support arm 232 and the fixed seat 22b1 can be protected to a certain extent, reducing the situation where foreign matter or dust falls at the connection between the two and causes jamming, and the working stability is good.

[0070] In one embodiment, please refer to Figure 2 、 Figure 4 、 Figure 6 and Figure 7 A rotating shaft A is formed in one of the fixing seat 22b1 and the supporting arm 232, and a rotating hole B is formed in the other of the fixing seat 22b1 and the supporting arm 232, and the rotating shaft A and the rotating hole B are rotatably matched.

[0071] For example, the fixing seat 22b1 may be formed with a rotation hole B, and the support arm 232 may be formed with a rotation axis A. In this way, the rotation of the cover 23 and the housing 21 is achieved through the rotation of the rotation axis A, and the rotation is relatively stable.

[0072] In one embodiment, please refer to Figures 6 to 8The support arm 232 is formed with a boss 2321 and a hook groove 2322, the shell 21 is formed with a limiting rib 21d, the elastic member 24 is sleeved on the boss 2321, one end of the elastic member 24 is set in the hook groove 2322, and the other end of the elastic member 24 is connected to the limiting rib 21d. In the first state, the support arm 232 drives one end of the elastic member 24 to approach the limiting rib 21d, and the elastic member 24 stores elastic potential energy. In the second state, the elastic member 24 restores its deformation to push the support arm 232 away from the limiting rib 21d.

[0073] Illustratively, the boss 2321 can be positioned on a side of the support arm 232 relative to the rotation axis A along the left-right direction of the base station 2. One end of the stopper can be positioned on the top wall of the mounting cavity 21b on the side of the rotation axis A away from the guide groove 21a along the guide direction. The other end of the stopper 21d extends downward. The hook groove 2322 can be positioned on a side of the support arm 232 near the boss 2321, extending through the base station 2 along the left-right direction. The elastic member 24 can be sleeved around the boss 2321, with one end of the elastic member 24 bent to fit within the hook groove 2322, and the other end of the elastic member 24 connected to the stopper 21d.

[0074] Here, when the cover body 23 is pushed to rotate by the floor brush 1 to cover and open the cutting piece 22, the support arm 232 will drive one end of the elastic piece 24 to rotate and approach the limiting rib 21d. Since the other end of the elastic piece 24 is limited by the limiting rib 21d, the elastic piece 24 will deform at this time and store elastic potential energy; when the floor brush 1 is removed, the cover body 23 is no longer blocked by the floor brush 1, and the elastic piece 24 will restore its deformation so that one end of it can push the support arm 232 away from the limiting rib 21d, so that the cover body 23 rotates back to its original position and covers the cutting piece 22.

[0075] In one embodiment, the elastic member 24 is a torsion spring. The torsion spring used as the elastic member 24 can withstand large deformation forces without damage and has good stability and reliability.

[0076] In one embodiment, please refer to Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 The cover plate 231 includes a shielding plate 2311 and a supporting plate 2312. The shielding plate 2311 is connected to the support arm 232. The shielding plate 2311 is used to shield or avoid the cutting piece 22. The supporting plate 2312 is connected to the shielding plate 2311. The supporting plate 2312 is used to contact the floor brush 1 in the first state. The part of the supporting plate 2312 that contacts the floor brush 1 is protruded toward the floor brush 1.

[0077] For example, the support arm 232 can be connected to the bottom surface of the shielding plate 2311. The shielding plate 2311 can shield the top of the cutting groove 21a2 and the side of the cutting groove 21a2 close to the sliding groove 21a1 along the guide direction in the second state. The supporting plate 2312 can be connected to one end of the shielding plate 2311.

[0078] Here, by setting the part of the supporting plate 2312 that contacts the floor brush 1 to protrude toward the floor brush 1, that is, the contact surface between the supporting plate 2312 and the floor brush 1 is a curved surface, the contact friction between the supporting plate 2312 and the floor brush 1 can be reduced, and the situation where the floor brush 1 gets stuck during movement and the cover body 23 cannot be rotated to avoid the cutting piece 22 can be reduced, thereby improving the working stability.

[0079] In one embodiment, please refer to Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 The shielding plate 2311 includes a first plate 23111 and a second plate 23112. The support arm 232 and the second plate 23112 are both connected to one side of the first plate 23111 along its thickness direction. The supporting plate 2312 is connected to the side of the second plate 23112 along its thickness direction away from the support arm 232. The supporting plate 2312 has an arc edge 2312a, which is located on the side of the supporting plate 2312 away from the second plate 23112. The arc edge 2312a is used to contact the floor brush 1 in the first state.

[0080] Illustratively, the second plate 23112 is connected to one side of the first plate 23111 along its thickness direction so that the shielding plate 2311 is in an "L" shape. In the second state, the first plate 23111 can shield the top of the cutting groove 21a2, and the second plate 23112 can shield the side of the cutting groove 21a2 close to the sliding groove 21a1 along the guide direction. In this way, the cutting member 22 can be protected in multiple directions in the second state.

[0081] One end of the supporting plate 2312 is connected to the side of the second plate 23112 away from the support arm 232 along its thickness direction. The side of the supporting plate 2312 away from the second plate 23112 is an arc edge 2312a. The arc edge 2312a is used to contact the floor brush 1 in the first state, so that during the rotation of the cover body 23, there is line-surface contact between the supporting plate 2312 and the floor brush 1. In this way, the contact friction between the supporting plate 2312 and the floor brush 1 can be further reduced.

[0082] In one embodiment, please refer to Figure 8 There are multiple supporting plates 2312 , and the multiple supporting plates 2312 are spaced apart in the axial direction of the rotation axis of the cover body 23 .

[0083] Exemplarily, the number of supporting plates 2312 can be 6, and the 6 supporting plates 2312 are divided into 2 groups, each group has 3 supporting plates 2312, the 3 supporting plates 2312 in each group are arranged with a first spacing size, and the 2 groups of supporting plates 2312 are arranged along a second spacing size, and the first spacing size is smaller than the second spacing setting. In this way, the bearing stability of the floor brush 1 can be improved.

[0084] In one embodiment, please refer to Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 The cover plate 231 includes a cover plate 2313, which connects multiple supporting plates 2312 along the thickness direction of the first plate 23111 to form a whole. In this way, the structural strength of the supporting plates 2312 can be improved to withstand a larger thrust from the floor brush 1.

[0085] In one embodiment, please refer to Figure 2 In the process of the floor brush 1 entering the guide groove 21 a , the position where the floor brush 1 first contacts the supporting plate 2312 is the first position C, and the first position C is lower than the top surface of the supporting plate 2312 .

[0086] That is to say, in the process of the floor brush 1 entering the guide groove 21a, the position where the floor brush 1 first contacts the supporting plate 2312 is located below the top surface. In this way, in the subsequent continuous pushing process, the supporting plate 2312 can be lifted up and rotated more easily, thereby further reducing the jamming between the floor brush 1 and the supporting plate 2312.

[0087] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, and improvements that fall within the spirit and principles of the present application are intended to be within the scope of protection of the present application.
