[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0038] Here, it should be noted that in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution of the present invention are shown in the drawings, while other details less relevant to the present invention are omitted.

[0039] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0040] As Figures 1 to 9 shown, the present invention discloses a cleaning device (not shown), and the cleaning device may be a floor cleaning robot or a hand-held floor washer, and the present invention is not limited thereto.

[0041] The cleaning device includes a cleaning means 100 capable of performing cleaning. The cleaning means 100 is modularly arranged below the cleaning device. The cleaning means 100 is detachably connected to the cleaning device, and the cleaning means 100 includes, but is not limited to, a mopping unit and a sweeping unit, and can be replaced according to needs. The cleaning components in the cleaning means 100 can be displaced relative to the cleaning device in the axial direction (for example, the axial direction of the rotation axis of the cleaning components, that is, the axial extension direction of the cleaning members, or the axial direction) to perform edge cleaning on the surface to be cleaned, thereby improving the user experience. For the sake of clarity, the following description in the specification will detail the specific structure of the cleaning means 100. It should be noted that the axial direction throughout the text refers to the same axial direction, that is, the axial direction of the rotation axis.

[0042] Please refer to Figures 1 to 9 shown, the cleaning means 100 includes a base 10, a cleaning component and a driving displacement component 40. The cleaning means 100 is connected to the cleaning device through the base 10. The cleaning component is used to clean the surface to be cleaned. The driving displacement component 40 can drive the cleaning component to reciprocate relative to the base 10 so that the cleaning component can at least partially extend out of the base 10, thereby enabling edge cleaning and avoiding cleaning blind spots.

[0043] The base 10 is the main frame of the cleaning device 100. The base 10 can be installed on the cleaning equipment and is connected to other components of the cleaning equipment, including but not limited to the traveling component, the clean water tank, the sewage tank and other structures. The base 10 is provided with a receiving cavity for receiving the cleaning component, and most of the cleaning component is received in the receiving cavity of the base 10. At least one opening is provided at both ends of the receiving cavity (both ends in the axial direction of the rotation axis of the cleaning component), and the opening is configured to allow the cleaning component to at least partially extend out of the base 10 along the opening.

[0044] The cleaning component includes a bracket 101, a cleaning member 20 and a liquid control component. The bracket 101 is movably connected to the base 10 through a driving displacement component 40. The cleaning member 20 can rotate relative to the bracket 101, and the liquid control component is fixed on the bracket 101 and moves synchronously with the bracket 101.

[0045] The cleaning component further includes a rotating shaft 22 for driving the cleaning member 20 to rotate relative to the bracket 101. In one embodiment, the cleaning member 20 is a roller 21. The cleaning member 20 can be sleeved outside the rotating shaft 22. A positioning portion 211 is provided inside the roller 21, and a limiting portion 221 cooperating with the positioning portion 211 is provided at the end of the rotating shaft 22. The limiting portion 221 and the positioning portion 211 can be installed in cooperation along the axial direction of the rotating shaft 22, so that the roller 21 can be installed in cooperation with the rotating shaft 22, and the rotating shaft 22 can drive the roller 21 to rotate synchronously when rotating. Of course, in other embodiments, the cleaning member 20 can also be a mop or a disposable cleaning member sleeved outside the rotating shaft 22.

[0046] The bracket 101 can be arc-shaped and cover the cleaning member 20. The bracket 101 can be located on the side close to the base 10 and can cover the cleaning member 20 as a lid of the cleaning member 20 to play a role in protecting and receiving the cleaning member 20. At the same time, in the present invention, the bracket 101 serves as a pushing member for pushing the cleaning member 20 to reciprocate relative to the base 10 along the axial direction of the rotating shaft 22. That is, the cleaning member 20 is driven to move axially through the bracket 101.

[0047] The bracket 101 includes a bracket body 1011 and a pushing portion 1012 provided on the bracket body 1011. The bracket body 1011 can extend along the axial direction of the cleaning member 20 and cover the cleaning member 20. The pushing portion 1012 can be provided at the end of the bracket body 1011 and extend from the bracket body 1011 towards the cleaning member 20 to drive the cleaning member 20 to move along the axial direction of the rotating shaft 22 through the pushing portion 1012.

[0048] The liquid control component includes a water spraying component 30 and a wiper 33. The water spraying component 30 is in waterway communication with the bracket 101 and supplies liquid to the cleaning member 20 through the bracket 101. The wiper 33 is in interference contact with the cleaning member 20. The cleaning member 20 can be self-cleaned through the liquid control component, improving the cleaning effect and cleaning efficiency.

[0049] The water spraying component 30 is fixed on the bracket 101, and the water spraying component 30 is connected to the fresh water tank of the cleaning device through a hose. A water pump is provided in the fresh water tank to supply liquid to the cleaning member 20 through the water spraying component 30. This liquid can be fresh water, cleaning liquid, or a mixture of both, so that the cleaning member 20 remains just moist, thereby improving the cleaning ability of the cleaning member 20.

[0050] Combined Figure 4 and Figure 5 As shown in the figure, as a preferred embodiment of the present invention, the water spraying component 30 is provided with a water inlet interface 31, and a water spraying pipe communicating with the water inlet interface 31 is provided between the water spraying component 30 and the bracket 101. A plurality of water spraying holes are formed on one side of the bracket body 1011 of the bracket 101 facing the cleaning member 20, and the water spraying holes are used to spray liquid onto the cleaning member 20.

[0051] Furthermore, the wiper 33 is arranged on the bracket body 1011 of the bracket 101 and is located on the opposite side of the water spraying component 30, and is in interference contact with the cleaning member 20. After the water spraying component 30 sprays liquid onto the cleaning member 20, the wiper 33 can scrape off the excess water on the cleaning member 20, so that the cleaning member 20 maintains an appropriate moisture level, thereby improving the cleaning effect. In addition, the wiper 33 can also scrape off the sewage and dirt on the cleaning member 20, thereby cooperating with the water spraying component 30 to achieve self-cleaning of the cleaning member 20.

[0052] Since both the wiper 33 and the water spraying component 30 are connected to the bracket 101, when the bracket 101 drives the cleaning member 20 to displace relative to the base 10, the wiper 33 and the water spraying component 30 can displace synchronously relative to the base 10.

[0053] In this embodiment, the driving displacement assembly 40 is disposed at the top of the receiving cavity. The driving displacement assembly 40 is connected to the bracket 101 through a first transmission member 411. Moreover, the bracket 101 is movably connected to the base 10 through the driving displacement assembly 40. The driving displacement assembly 40 moves relative to the base 10 to drive the bracket 101 to generate a displacement in the axial direction, and drives the cleaning member 20, the water spraying assembly 30, and the wiper blade 33 to displace in the axial direction of the cleaning member 20 through the bracket 101, so that at least one end of the cleaning member 20, the water spraying assembly 30, and the wiper blade 33 in the axial direction can at least partially extend outside the cleaning device, enabling the cleaning member 20 to clean against edge areas such as the corner of a wall, reducing or avoiding cleaning blind spots, and improving the user experience. At this time, the cleaning member 20 has a part located in the receiving cavity of the base 10 and another part located outside the base 10.

[0054] The driving displacement assembly 40 includes a first transmission member 411 and a second transmission member 431. Among them, the first transmission member 411 is fixedly connected to the bracket 101, and the second transmission member 431 is fixedly connected to the base 10. Under the driving force of the displacement motor 41, the first transmission member 411 can displace relative to the second transmission member 431 along the axial direction of the cleaning member 20, and drive the cleaning member 20 and the water spraying assembly 30 to displace along the axial direction through the bracket 101, so that at least one end of the cleaning assembly in the axial direction can at least partially extend out of the base 10, enabling the cleaning member 20 to clean against edge areas such as the corner of a wall, without cleaning blind spots, and improving the user experience.

[0055] Optionally, the driving displacement assembly 40 further includes a displacement motor 41. One of the first transmission member 411 and the second transmission member 431 is a rack extending in the axial direction, and the other is a gear meshed with the rack. The gear is fixedly connected and in transmission connection with the displacement motor 41. Alternatively, in other embodiments, the first transmission member 411 and the second transmission member 431 can also be wedge blocks, springs, gears and gear discs, etc., and the present invention is not limited thereto.

[0056] In this embodiment, the first transmission member 411 is a gear, and the second transmission member 431 is a rack. The first transmission member 411 is fixedly connected to the displacement motor 41. When the displacement motor 41 rotates, it drives the gear to reciprocate along the extension direction of the rack (i.e., the axial direction), thereby driving the bracket 101 to reciprocate relative to the base 10 along the axial direction, so as to realize the reciprocating movement of the entire cleaning assembly. In other embodiments, the first transmission member 411 can also be a rack, and the second transmission member 431 is a gear. The gear is fixed on the base 10 and is rotationally connected to the displacement motor 41 and driven by the displacement motor 41. Since the gear is fixed and the gear and the rack are meshed and connected, the rack can move relative to the gear.

[0057] Further, the bracket 101 is connected to the first transmission member 411 through a fixing block 32. Since the bracket 101 is disposed in the lower receiving cavity of the base 10 and the displacement motor 41 is disposed above the base 10, a relief groove 11 for the fixing block 32 to pass through is provided on the base 10. Of course, in other embodiments, if the displacement motor 41 is also disposed below the base 10, the relief groove 11 may not be provided on the base 10.

[0058] Further, in order to ensure that the moving directions of the first transmission member 411 and the second transmission member 431 do not deviate, the present invention provides a first guiding member 42 and a second guiding member 43 connected in a sliding manner. The first transmission member 411 is connected to the first guiding member 42, and the second transmission member 431 is connected to the second guiding member 43. The first guiding member 42 is fixedly arranged with the displacement motor 41 and configured to be able to slide relative to the second guiding member 43.

[0059] In this embodiment, the first guiding member 42 is a slider, which is fixedly connected to the bracket 101 through a fixing block 32. The second guiding member 43 is a guide rail, which is fixedly arranged on the base 10. Among them, the extension direction of the guide rail is the axial direction of the cleaning member 20. The first guiding member 42 can cover the second guiding member 43, so that the second transmission member 431 is clamped between the first transmission member 411 and the first guiding member 42, and the second transmission member 431 and the first transmission member 411 can be in close contact and meshed. Of course, in other embodiments, the first guiding member 42 can also be a guide rail, and the second guiding member 43 can be a slider.

[0060] Furthermore, in order to improve the smoothness of the movement of the cleaning component, a guiding component 50 is further provided on the base 10. The guiding component 50 includes a first guiding member 51 and a second guiding member 52. The extending direction of the second guiding member 52 is the same as that of the second orienting member 43. The first guiding member 51 is fixedly connected to the bracket 101 through a fixing block 32. The second guiding member 52 is fixed on the base 10. The first guiding member 51 is configured to be able to slide relative to the second guiding member 52, which is equivalent to the first guiding member 51 and the second guiding member 52 cooperating to guide the cleaning component to displace along the axial direction. It can be understood that one of the first guiding member 51 and the second guiding member 52 is a guide rail extending along the axial direction, and the other is a slider slidably connected to the guide rail, and specific limitations are not made.

[0061] That is, when the first orienting member 42 slides along the second orienting member 43, the first guiding member 51 slides along the second guiding member 52, and the length of the second guiding member 52 is the same as that of the second orienting member 43.

[0062] In particular, in order to make the axial movement of the cleaning component more stable, the driving displacement component 40 and the guiding component 50 are located on the same horizontal plane, and the first orienting member 42 and the first guiding member 51 are respectively located on both sides of the bracket 101.

[0063] In particular, in order to control the stroke of the cleaning member 20 extending outwards, the driving displacement component 40 further includes a limiting structure 44 provided on the moving path of the bracket 101. Through the limiting structure 44, the cleaning member 20 can be stopped at an appropriate or required position, so that the distance between the cleaning member 20 and the wall is controllable.

[0064] In this embodiment, the limiting structure 44 is a microswitch, and there are at least two limiting structures 44. The at least two microswitches are arranged on the moving path of the first transmission member 411. In this embodiment, the limiting structure 44 includes a first limiting member 441 and a second limiting member 442. Both the first limiting member 441 and the second limiting member 442 are microswitches and are located at both ends of the first transmission member 411 in the axial direction. When the first transmission member 411 contacts the first limiting member 441, the cleaning assembly has a minimum displacement distance relative to the base 10. For example, the cleaning member 20 can be entirely below the base 10 and not exposed outside the base 10. That is, the minimum displacement distance can be 0. When the first transmission member 411 contacts the second limiting member 442, the cleaning assembly has a maximum displacement distance relative to the base 10. That is, at this time, at least one end of the cleaning member 20 is exposed outside the base 10, so that it can extend out of the base 10 to clean the area outside the base 10. When the cleaning assembly has the maximum displacement distance relative to the base 10, it is also the maximum distance that the cleaning member 20 can extend out of the base 10.

[0065] In this embodiment, the first guiding member 42 covering the outside of the first transmission member 411 is on the same straight line as the limiting structure 44. When the first guiding member 42 touches the limiting structure 44, the displacement motor 41 can stop working. That is, when the bracket 101 drives the cleaning member 20, the water spraying assembly 30 and the wiper 33 to move outwards synchronously, when the first guiding member 42 contacts the second limiting member 442, the displacement motor 41 stops working. At this time, the cleaning member 20 has the maximum displacement distance. When the bracket 101 drives the cleaning member 20, the water spraying assembly 30 and the wiper 33 to move inwards synchronously, when the first guiding member 42 contacts the first limiting member 441, the displacement motor 41 stops working. At this time, the cleaning member 20 has the minimum displacement distance.

[0066] It can be understood that when the first transmission member 411 contacts the first limiting member / the second limiting member, the displacement motor 41 stops rotating, and when it is restarted, it rotates in the direction opposite to the previous rotation direction.

[0067] Further, the limiting structure 44 may further include a number of third limiting members (not shown) arranged between the first limiting member 441 and the second limiting member 442. The third limiting members make the cleaning assembly have an intermediate displacement distance between the minimum displacement distance and the maximum displacement distance relative to the base 10. That is, by setting the third limiting members, the distance that the cleaning assembly is exposed outside the base 10 can be adjusted, and the distance that the cleaning assembly is exposed can be adjusted according to the cleaning environment, improving the applicable range of the cleaning device.

[0068] Furthermore, in order to drive the cleaning member 20 to rotate for cleaning, the cleaning device 100 further includes a driving rotation assembly 60, wherein the driving rotation assembly 60 is rotationally connected to the cleaning member 20 to drive the cleaning member 20 to rotate relative to the bracket to clean the surface to be cleaned.

[0069] In this embodiment, when the driving displacement assembly 40 drives the bracket 101 and drives the cleaning member 20 to displace in the axial direction through the bracket 101, the driving rotation assembly 60 and the cleaning assembly are displaced synchronously.

[0070] Specifically, the driving rotation assembly 60 includes a rotating motor 61 and a tooth box 62 , the tooth box 62 has an input end 621 and an output end 622 , the output end of the rotating motor 61 is transmission connected to the input end 621 of the tooth box 62 , and the output end 622 of the tooth box 62 is transmission connected to the cleaning member 20 .

[0071] It can be understood that the extension direction of the input end 621 is parallel to the extension direction of the output end 622, the extension direction of the rotating shaft 22 of the rotating motor 61 is parallel to the extension direction of the cleaning member 20, and a transmission structure is provided between the input end 621 and the output end 622 for transmission, that is, when the input end 621 is input with power, the output end 622 can output the power provided by the input end 621, so that when the rotating motor 61 and the cleaning member 20 are not in the same straight line, the rotating motor 61 can drive the cleaning member 20 to perform cleaning operations. In this way, the space of the base 10 can be reasonably utilized to reduce the volume of the cleaning device. At the same time, the output end 622 is locked with the cleaning member 20 by a fastener.

[0072] In this embodiment, the driving rotating assembly 60 is arranged on the outside of the cleaning member 20, and the base 10 is also provided with a yielding portion (not shown) for driving the rotating assembly to move in the axial direction. When the cleaning member 20 moves under the drive of the displacement motor 41, the cleaning member 20 drives the tooth box 62 and the rotating motor 61 to move synchronously, and during the movement, the relative positions of the cleaning member 20, the tooth box 62 and the rotating motor 61 remain unchanged, that is, when the cleaning member 20 moves along the accommodating cavity, the rotating motor 61 moves along the yielding portion, and the displacement generated by the rotating motor 61 relative to the yielding portion is the same as the displacement generated by the cleaning member 20, that is, the rotating motor 61 and the cleaning member 20 are displaced synchronously.

[0073] The moving process of the cleaning component of the cleaning device 100 in this embodiment is as follows: When the displacement motor 41 drives the first transmission member 411 to displace axially relative to the second transmission member 431, the bracket 101 moves driven by the first transmission member 411, and drives the entire cleaning component (including the cleaning member 20, the water spraying component 30, and the wiper 33) to displace axially (for example, extend out of the base to the right) through the pushing portion 1012, so that the cleaning component can at least partially extend out of the base 10 for edge cleaning. When it is necessary to retract the cleaning component, the displacement motor 41 can be rotated in the reverse direction, thereby driving the first transmission member 411 to move axially in the reverse direction relative to the second transmission member 431. The bracket 101 moves in the reverse direction driven by the first transmission member 411. At this time, the cleaning member 20 can be driven to move in the reverse direction by the pushing portion on the other side (not shown), or the gearbox 62 can be pushed to move in the reverse direction by the pushing portion 1012 (please refer to Figure 7 As shown, the pushing portion 1012 is arranged between the gearbox 62 and the cleaning member 20), and then the cleaning member 20 is driven to move in the reverse direction by driving the rotating component 60, and is retracted into the base 10. Since the water spraying component 30 and the wiper 33 are fixedly connected to the bracket 101, they move synchronously.

[0074] As another embodiment of the present invention, the driving rotating component 60 can also be arranged inside the cleaning member 20. That is, the rotating motor 61 is arranged inside the rotating shaft 22. When the driving displacement component 40 drives the bracket 101 and drives the cleaning member 20 to displace axially through the bracket 101, the driving rotating component 60 displaces synchronously with the cleaning component.

[0075] In another embodiment of the present invention, the driving rotating component 60 can be fixedly arranged with the base 10, that is, the gearbox 62 and the rotating motor 61 do not move relative to the base 10. Thus, when the cleaning member 20 moves outwards, the cleaning member 20 moves relative to the gearbox 62 and the rotating motor 61, that is, the cleaning member 20 moves axially relative to the output end 622. To ensure that the cleaning member 20 and the output end 622 do not come out, at this time, the length of the output end 622 needs to be greater than the displacement distance of the cleaning component.

[0076] In this embodiment, since the gearbox 62 is provided at one end of the cleaning member 20 and is drivingly connected to the cleaning member 20 through the rotating shaft 22. Therefore, when the cleaning member 20 is pushed by the bracket 101 to move in the axial direction, one end of the cleaning member 20 away from the gearbox 62 can partially extend out of the base 10 to clean the surface to be cleaned. In other embodiments of the present invention, the driving and rotating assembly 60 can also be provided at the middle position of the cleaning member 20. At this time, the cleaning member 20 has a first part and a second part arranged in the axial direction, the driving and rotating assembly 60 is arranged between the first part and the second part, and the cleaning member 20 is configured to move in two left and right directions under the drive of the driving displacement assembly 40. With such a setting, it is equivalent to that the cleaning member 20 can freely protrude left or right to clean the left or right area to be cleaned. Or, when the driving and rotating assembly 60 is arranged inside the rotating shaft 22, the driving displacement assembly 40 can also be used to drive the bracket 101 to drive the cleaning member 20 to displace in two left and right directions.

[0077] Further, when the cleaning member 20 and the rotating shaft 22 are detachably connected, it is convenient to replace the cleaning member 20.

[0078] The cleaning member 20 is further provided with a locking component 23, that is, the locking component 23 is located at the end of the cleaning member 20 (such as the drum 21) in the axial direction (for example, it can be the end away from the gearbox 62). The locking component 23 is fixedly connected to the cleaning member 20 and is configured to fix the cleaning member 20 on the rotating shaft 22, or detach the cleaning member 20 from the rotating shaft 22.

[0079] Combined Figure 7 and Figure 8 As shown, specifically, the locking component 23 includes a locking piece 231, an end cover 232 and an elastic member 233. The end cover 232 is fixedly connected to the cleaning member 20. The locking piece 231 is slidably connected inside the end cover 232. The elastic member 233 is arranged between the locking piece 231 and the end cover 232 and is configured to provide an elastic acting force to reset the locking piece 231 and provide a pressing distance for the pressing end. The locking piece 231 includes a pressing end and a buckling portion 2311. The pressing end and the buckling portion 2311 are connected. A pulling portion for pulling out the cleaning member 20 is provided at the pressing end. The rotating shaft 22 has an opening for the buckling portion 2311 to extend into. A clamping portion 222 extending radially inward is provided at the opening. The buckling portion 2311 is used to cooperate with the clamping portion 222 of the rotating shaft 22 for locking.

[0080] When pressing the pressing end of the locking part 231, the locking part 231 drives the buckling part 2311 to disengage from the locking with the rotating shaft 22. In this way, after the locking component 23 is removed, the roller 21 can be removed from the rotating shaft 22.

[0081] As Figure 9 shown, in another embodiment of the present invention, at the other end of the bracket 101 relative to the gearbox 62, a connecting bracket 103 for fixing the cleaning part 20 can also be provided. The connecting bracket 103 is pivotally and detachably connected to the cleaning part 20, so that the cleaning part 20 can rotate around the connecting bracket 103. Moreover, through the connecting bracket 103, the cleaning part 20 can be pushed to move inward in the axial direction, that is, the cleaning part 20 moves from the maximum displacement distance to the minimum displacement distance.

[0082] In summary, for the cleaning device 100 of the present invention and the cleaning equipment having the cleaning device 100, by providing the driving displacement component 40 connected to both the bracket 101 and the base 10, the displacement motor 41 can drive the first transmission part 411 to displace axially relative to the second transmission part 431, so that the bracket 101 can displace axially relative to the base 10. Furthermore, at least one end of the entire cleaning component can partially extend out of the base 10 along the axial direction through the bracket 101, enabling the cleaning component to fit the wall edge for cleaning, reducing the blind areas and dead corners at the wall edge, and improving the cleaning rate.

[0083] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
