[0039] See also Figures 1 to 9 As shown, according to an embodiment of the present application, a cleaning device is provided, which may be, for example, a sweeping robot or a cleaning base station, etc. The cleaning device includes a main body 10 , a roller assembly 20 and a locking assembly 30 .

[0040] The bottom of the main body 10 is provided with a first mounting groove 11, a first limiting portion 12 and a locking portion 13, and the first limiting portion 12 is located at the side wall of the first mounting groove 11. The roller assembly 20 includes a roller 22 and a first connecting portion 21, the roller 22 is sleeved on the first connecting portion 21 and can rotate around its own axis relative to the first connecting portion 21, and the first connecting portion 21 has an end connecting body 211 protruding from the roller 22. The locking assembly 30 includes a second limiting portion 33 and a locking portion 32, and the locking assembly 30 includes an unlocking position and a locking position. The locking assembly 30 is rotatably connected to the main body 10 to switch between the unlocking position and the locking position. When the locking assembly 30 is in the locking position, the second limiting portion 33 and the first limiting portion 12 are attached and enclosed to form a locking space for fixing the end connecting body 211, and the locking portion 32 is matched and connected with the locking portion 13. When the locking assembly 30 is in the unlocking position, the locking portion 32 is disengaged from the locking portion 13 , and the second limiting portion 33 is separated from the first limiting portion 12 to unlock the end connector 211 .

[0041] Specifically, the outer periphery of the drum 22 is provided with a wiping cloth 23. When the drum 22 rotates, the drum 22 drives the wiping cloth 23 to rotate, thereby cleaning the floor. When the drum 22 needs to be disassembled and maintained, the locking assembly 30 is first rotated to the unlocking position to separate the locking portion 32 from the locking portion 13. At this time, the first limiting portion 12 and the second limiting portion 33 unlock the end connecting body 211, the main body 10 has no fixing effect on the first connecting portion 21, and the drum 22 can be removed from the first installation groove 11. When the drum 22 needs to be installed, the other end of the drum 22 is first installed in the first installation groove 11. Subsequently, the end connecting body 211 is placed on the first limiting portion 12, and the locking assembly 30 is rotated to the locking position so that the locking portion 13 and the locking portion 32 are matched and connected, thereby forming a locking space between the first limiting portion 12 and the second limiting portion 33 to lock the end connecting body 211. Through the structure of this embodiment, the drum 22 can be quickly disassembled or assembled.

[0042] In addition, in some embodiments, both ends of the roller 22 are provided with a first connecting portion 21, and the end connecting bodies 211 at both ends of the roller 22 are locked to the main body 10 of the cleaning device through the locking assembly 30. In some other embodiments, one end of the roller 22 is connected to the main body 10 of the cleaning device through a screw, and the other end of the roller 22 is fixed to the main body 10 of the cleaning device through the cooperation of the locking assembly 30 and the end connecting body 211.

[0043] Further, the first limiting portion 12 includes a first limiting groove 121. The locking assembly 30 includes a locking member 31, one end of which is rotatably connected to the main body 10, and the second limiting portion 33 is a second limiting groove 311 provided on the locking member 31. When the locking member 31 is in the locked position, the first limiting groove 121 and the second limiting groove 311 are engaged and enclosed to form a locking space.

[0044] Specifically, the first limiting groove 121 is connected to the first installation groove 11. When installing the roller 22, the end connector 211 is installed in the first limiting groove 121. Then, the locking member 31 is rotated to make the second limiting groove 311 engage with the first limiting groove 121, thereby forming a locking space. At this time, the end connector 211 is located in the locking space, and then the locking member 31 cooperates with the locking portion 13, so that the locking member 31 is fixedly connected to the locking portion 13, and finally the roller 22 is fixed to the main body 10 of the cleaning device.

[0045] Of course, in some embodiments, the first limiting portion 12 can be a plane, and the end connector 211 can be locked by simply using the locking space formed by the second limiting groove 311 and the plane. Similarly, the first limiting portion 12 is the first limiting groove 121, and the second limiting portion 33 is a plane, so that the roller 22 can be fixed to the main body 10.

[0046] Furthermore, a second mounting groove 312 is provided on the locking member 31, and the locking portion 32 includes a locking tongue 321 and an elastic member 322. The locking tongue 321 is installed in the second mounting groove 312, and the two ends of the elastic member 322 respectively abut against the locking tongue 321 and the bottom of the second mounting groove 312. The locking tongue 321 is extended out of the outer edge of the locking member 31 by the elastic force applied by the elastic member 322 to cooperate with the locking portion 13 and be in a locked position. The locking tongue 321 is acted upon by an external force and overcomes the elastic force applied by the elastic member 322 to the locking tongue 321 and retracts to the second mounting groove 312 and is in an unlocked position.

[0047] Specifically, when the locking member 31 rotates until the second limiting groove 311 is in contact with the first limiting groove 121, the locking tongue 321 is extended out of the second installation groove 312 by the elastic force applied by the elastic member 322, and cooperates with the locking portion 13, so that the locking member 31 is locked by the locking portion 13, and the end connector 211 is locked in the locking space. When the end connector 211 is unlocked, an external force is first applied to the locking tongue 321, so that the locking tongue 321 overcomes the elastic force applied by the elastic member 322 to the locking tongue 321, and the locking tongue 321 is retracted into the second installation groove 312. At this time, the locking tongue 321 is separated from the locking portion 13, and then the locking member 31 is rotated to the position where the second limiting groove 311 is separated from the first limiting groove 121, so that one end of the drum 22 can be unlocked. In this embodiment, the elastic member 322 can be, for example, a spring or an elastic rubber sleeve.

[0048] Further, the locking portion 32 includes a card slot 131. The locking tongue 321 includes a supporting section 3211 and a protruding section 3212, the supporting section 3211 is connected to the protruding section 3212, one end of the elastic member 322 abuts against the protruding section 3212, a first through hole 3121 is provided on the side wall of the second mounting groove 312, the supporting section 3211 is arranged in the second mounting groove 312, and extends through the first through hole 3121, and the supporting section 3211 slides in the first through hole 3121 along the expansion and contraction direction of the elastic member 322 to drive the protruding section 3212 to be plugged into or separated from the card slot 131.

[0049] In this embodiment, the card slot 131 can be set on a side wall of the first installation groove 11, or on a side wall of the first limiting groove 121. For example, it can be set on the side wall surface of the first limiting groove 121 opposite to the extension direction of the end connecting body 211, or it can be set on one of the two opposite side walls of the first limiting groove 121 perpendicular to the extension direction of the end connecting body 211.

[0050] In a specific embodiment, the locking member 31 is rotatably connected to a side wall surface of the first limiting groove 121 which is perpendicular to and close to the end connecting body 211, and the clamping groove 131 is provided on a side wall opposite to the rotatable connection of the locking member 31. When the end connecting body 211 needs to be fixed, the locking member 31 is first rotated to fit with the first limiting groove 121, and then an external force is applied to the support section 3211 to compress the elastic member 322. After that, the external force applied to the support section 3211 is stopped, and the elastic member 322 rebounds to drive the support section 3211 to slide, and the support section 3211 slides to drive the protruding section 3212 to pass through the second mounting groove 312 and be inserted into the clamping groove 131 to complete the fixing of the end connecting body 211. When the end connecting body 211 needs to be unlocked, it is only necessary to apply an external force to the support section 3211 to compress the elastic member 322. At this time, the protruding section 3212 is separated from the slot 131 driven by the supporting section 3211 and retracts into the second mounting groove 312. Subsequently, the locking member 31 is rotated to a position separated from the first limiting groove 121 to complete the unlocking of the end connector 211.

[0051] Furthermore, a second through hole 3122 is formed through the side wall of the second mounting groove 312 .

[0052] In some embodiments, the first through hole 3121 and the second through hole 3122 are respectively provided on two opposite sidewalls of the second mounting groove 312. Specifically, when the locking member 31 is fitted with the first limiting groove 121, the first through hole 3121 is provided on a side of the second mounting groove 312 away from the first limiting groove 121, so as to apply an external force to the support section 3211. The second through hole 3122 is provided on a side of the second mounting groove 312 close to the first limiting groove 121, and along the extension direction of the first through hole 3121, the projection area of ​​the second through hole 3122 is greater than or equal to the projection area of ​​the locking portion 13, so as to facilitate the installation of the support section 3211 and the protruding section 3212 in the second mounting groove 312. In addition, when the support section 3211 and the protruding section 3212 are separately connected, along the extension direction of the first through hole 3121, the projection area of ​​the second through hole 3122 can be smaller than the projection area of ​​the locking portion 13. Of course, the first through hole 3121 can be opened on the bottom surface of the second installation groove 312 , and the second through hole 3122 can also be opened on other side wall surfaces of the second installation groove 312 .

[0053] Furthermore, a positioning protrusion 15 is disposed on one of the locking member 31 and the first limiting portion 12 , and a positioning hole 313 matched with the positioning protrusion 15 is disposed on the other of the two.

[0054] In a specific embodiment, a positioning hole 313 is provided on the side wall surface of the second installation groove 312 on the locking member 31, and a positioning protrusion 15 is provided on the groove bottom surface of the first limiting groove 121. When the locking member 31 is rotated to fit with the first limiting groove 121, the positioning protrusion 15 can be inserted into the positioning hole 313, thereby limiting the locking member 31 and improving the connection stability between the locking member 31 and the first limiting groove 121. In some embodiments, the positioning hole 313 and the positioning protrusion 15 are both included in plurality, so as to further improve the connection strength between the locking member 31 and the first limiting groove 121.

[0055] Optionally, the positioning protrusion 15 can be provided on the locking member 31 , and the positioning hole 313 can be provided on the first limiting portion 12 . As long as it is other deformation methods based on the concept of the present application, it is within the protection scope of the present application.

[0056] In order to improve the structural strength of the locking member 31, a reinforcing rib 3111 is provided in the second limiting groove 311 in the present embodiment. Specifically, since the second limiting groove 311 is provided on the locking member 31, the structural strength of the locking member 31 is reduced. When the cleaning device is shaken by an external force, if the structural strength of the locking member 31 is too low, the locking member 31 may be damaged, thereby reducing the connection stability between the drum 22 and the main body 10, and finally causing the cleaning device to fail to work normally. In some embodiments, chamfers are provided between the side walls of the end connector 211, and the reinforcing rib 3111 is provided as a reinforcing rib 3111 adapted to the chamfers. While strengthening the structural strength of the locking member 31, the contact area with the end connector 211 is increased, thereby improving the locking effect of the locking member 31 on the end connector 211. Of course, a reinforcing rib 3111 adapted to the chamfer on the end connector 211 may also be provided in the first limiting groove 121.

[0057] Further, the end connecting body 211 includes a prism or an elliptical column, and the locking space includes a prism groove or an elliptical groove adapted to the end connecting body 211 .

[0058] Specifically, the end connector 211 of the prism or the end connector 211 of the elliptical column can prevent the end connector 211 from rotating in the locking space, thereby causing the end connector 211 to rub against the first limiting groove 121 or the second limiting groove 311, causing damage to the end connector 211. At the same time, the locking space is a prism groove or an elliptical groove to increase the contact area between the first limiting groove 121 and the second limiting groove 311 and the end connector 211 of the prism or the end connector 211 of the elliptical column. In addition, the prism includes a triangular prism, a quadrangular prism, a pentagonal prism, and a hexagonal prism. In some embodiments, the end connector 211 is a quasi-prism, that is, each prism is chamfered.

[0059] In addition, a first fixed shaft 14 is provided on the main body 10 . The first fixed shaft 14 extends in a direction parallel to the axis of the drum 22 . One end of the locking assembly 30 is rotatably sleeved on the first fixed shaft 14 .

[0060] In this embodiment, the locking assembly 30 is rotatably sleeved on the first fixed shaft 14 so that the locking assembly 30 can be switched between the unlocked position and the locked position. Specifically, the first fixed shaft 14 is arranged on the side wall of the first limiting groove 121 relative to the slot 131, and one end of the locking member 31 is rotatably sleeved on the first fixed shaft 14. When the end connector 211 needs to be locked, the locking member 31 is rotated to a position abutting against the first limiting groove 121. When the drum 22 needs to be disassembled, the support block is first controlled to retract the protruding section 3212 into the second mounting groove 312, and then the locking member 31 is rotated to a position separated from the first limiting groove 121.

[0061] In some embodiments, the drum assembly 20 also includes a second connecting portion 24, which is connected to the side wall of the first mounting groove 11, and the second connecting portion 24 has a first position that can be rotated to the outside of the first mounting groove 11 under the action of an external force and a second position that can be rotated to the inside of the first mounting groove 11 under the action of an external force. The drum 22 can be detachably mounted on the second connecting portion 24 and can rotate around its own axis relative to the second connecting portion 24.

[0062] Specifically, when the roller 22 needs to be disassembled, the end connector 211 is first unlocked, and then the second connector 24 is rotated to a second position away from the first mounting groove 11. Finally, the roller 22 is disassembled from the second connector 24. Conversely, when the roller 22 needs to be installed, the roller 22 is first installed on the second connector 24, and then the second connector 24 is rotated into the first mounting groove 11, so that the end connector 211 on the first connector 21 is located in the first limiting groove 121. Finally, the locking member 31 is rotated to a position that fits the first limiting groove 121, and the protruding section 3212 is inserted into the card slot 131. In this embodiment, the second connector 24 can be connected to the second fixed shaft provided on the side wall of the first mounting groove 11 by rotation, and the second connector 24 can also be connected to the side wall of the first mounting groove 11 by hinged manner.

[0063] In addition, the cleaning device also includes a driving component 40. In this embodiment, the driving component 40 includes a motor 401. The outer shell of the motor 401 is connected to the second connecting part 24. The output end of the motor 401 is passed through the drum 22 so that the drum 22 can rotate around its own axis relative to the first connecting part 21 and the second connecting part 24.

[0064] Furthermore, the first connecting portion 21 also has a rotating body 212, which is connected to a side of the end connecting body 211 away from the first mounting groove 11, and the rotating body 212 can rotate relative to the end connecting body 211 around its own axis direction, and the roller 22 is detachably sleeved on the outer periphery of the rotating body 212. Specifically, the rotating body 212 includes a rotating bearing 2121 and a sleeve 2122, the rotating bearing 2121 can rotate relative to the end connecting body 211 around its own axis direction, the sleeve 2122 is sleeved on the outer periphery of the rotating bearing 2121, and covers the outer periphery of part of the end connecting body, and the sleeve 2122 can rotate relative to the end connecting body 211 around its own axis direction under the drive of the rotating bearing 2121.

[0065] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0066] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0067] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
