[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0032] like Figure 1-4 As shown, this embodiment provides a cleaning and wiping disc, including:

[0033] The turntable assembly includes at least a first turntable 110 and a second turntable 120. A first cloth 310 and a second cloth 320 are respectively mounted on the first turntable 110 and the second turntable 120. The projection of the first cloth 310 on the cleaning robot is at least partially outside the second cloth 320.

[0034] The drive assembly includes a drive motor 210, a first transmission module 220, and a second transmission module 230. The drive motor 210 is connected to the first turntable 110 via the first transmission module 220, and the first turntable 110 is connected to the second turntable 120 via the second transmission module 230, so as to drive the first turntable 110 and the second turntable 120 to rotate in opposite directions.

[0035] The cleaning wiper disclosed in this application includes a turntable assembly and a drive assembly. The turntable assembly includes at least a first turntable 110 and a second turntable 120, with a first wiping cloth 310 and a second wiping cloth 320 respectively mounted on the first turntable 110 and the second turntable 120. The drive assembly includes a drive motor 210, a first transmission module 220, and a second transmission module 230. The drive motor 210 is connected to the first turntable 110 through the first transmission module 220, enabling the first turntable 110 and the output shaft of the drive motor 210 to rotate synchronously. The second turntable 120 is connected to the first turntable 110 through the second transmission module 230. Driven by the second transmission module 230, the second turntable 120 rotates in the opposite direction to the first turntable 110, and the first wiping cloth 310 and the second wiping cloth 320 rotate in different directions. By setting at least two turntables with different rotation directions, this application can wipe stubborn substances on the surface to be cleaned at different or opposite angles, which facilitates the removal of stubborn substances that are stuck to the surface to be cleaned, thereby improving the cleaning effect.

[0036] The first turntable 110 module can be connected to the drive motor 210 and the first turntable 110 respectively, so that the output shafts of the first turntable 110 and the drive motor 210 rotate synchronously. For example, the first transmission module 220 can be a combination gear, which can be composed of multiple gears. By having multiple gears mesh in sequence, the efficiency and smoothness of power transmission between the drive motor 210 and the first turntable 110 can be improved, and a larger torque can be output to the first turntable 110, so that the first turntable 110 can drive the second turntable 120 to rotate through the second transmission module 230.

[0037] The second transmission module 230 can be connected to the first turntable 110 and the second turntable 120 respectively. The second transmission module 230 can be a gear structure, with the first turntable 110 and the second turntable 120 meshing with the same gear respectively. When the first turntable 110 rotates, it can drive the second turntable 120 to rotate through the second transmission module 230, thereby causing the first turntable 110 and the second turntable 120 to rotate in different directions.

[0038] Additionally, it should be noted that in some embodiments, the turntable assembly may also include a third turntable, a fourth turntable, etc. Similarly, the third turntable and the fourth turntable are respectively equipped with a third wiping cloth and a fourth wiping cloth. At least one of the first turntable 110, the second turntable 120, the third turntable and the fourth turntable rotates in a different or opposite direction than the other turntables.

[0039] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second turntable 120 is coaxially disposed around the first turntable 110.

[0040] The second turntable 120 can be circular, and the central axis of the second turntable 120 coincides with the central axis of the first turntable 110. Correspondingly, the second cloth 320 on the second turntable 120 is distributed around the first cloth 310. The first cloth 310 and the second cloth 320 rotate and wipe in different directions on the same horizontal plane. It has a better cleaning effect on some stubborn debris stuck to the surface to be cleaned.

[0041] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the second transmission module 230 includes a first gear 231, the first gear 231 is rotatably connected to the bottom of the cleaning robot, the outer wall of the first turntable 110 is provided with a first outer gear tooth 111, the inner wall of the second turntable 120 is provided with a first inner gear tooth 121, and the first outer gear tooth 111 meshes with the first inner gear tooth 121 through the first gear 231.

[0042] Specifically, the outer wall of the first turntable 110 has a first outer gear tooth 111, and the inner wall of the second turntable 120 has a first inner gear tooth 121. The first gear 231 meshes with the first outer gear tooth 111 and the first inner gear tooth 121 respectively. The first gear 231 is rotatably mounted at the bottom of the cleaning robot. For example, the drive motor 210 drives the first turntable 110 to rotate clockwise through the first transmission module 220. At this time, the first gear 231 rotates counterclockwise. Correspondingly, the second turntable 120 rotates counterclockwise, thereby realizing that the first turntable 110 and the second turntable 120 rotate in different directions.

[0043] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of first gears 231 is multiple, and the multiple first gears 231 are distributed at intervals in the gap between the first outer gear teeth 111 and the first inner gear teeth 121.

[0044] Specifically, there are multiple first gears 231, which are spaced apart in the gap between the first turntable 110 and the second turntable 120. By having multiple first gears 231 mesh with the first outer gear teeth 111 and the first inner gear teeth 121 respectively, the load on each first gear 231 can be reduced, thereby extending its service life. Furthermore, this design may also help balance radial forces, reduce bearing stress, and improve the overall system stability. In some embodiments, the number of first gears 231 is eight.

[0045] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further includes a gearbox cover 232, which is connected to the bottom of the cleaning robot and covers the plurality of first gears 231.

[0046] The gearbox cover 232 can be a metal or non-metal shell structure. For example, the gearbox cover 232 is a plastic shell and is ring-shaped. The gearbox cover 232 can be fixedly installed on the bottom of the cleaning robot, and a gap is formed between the gearbox cover 232 and the bottom of the cleaning robot for installing the first gear 231. Specifically, the gearbox cover 232 and the bottom of the cleaning robot are respectively provided with a first annular groove. The two shaft ends of the first gear 231 are respectively inserted into the two first annular grooves, realizing the rotational connection between the first gear 231 and the bottom of the cleaning robot. At the same time, the gearbox cover 232 can effectively prevent garbage or hair from entering the interior, which could cause the first gear 231 to seize up and fail to work properly.

[0047] This embodiment, by setting the gearbox cover 232, can prevent garbage, hair, debris and other things from accidentally entering the gearbox and causing jamming or damage, thereby improving the stability and service life of the cleaning and wiping disc.

[0048] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the first transmission module 220 includes a drive gear 221, a coupling 222 and a connecting seat 223. The connecting seat 223 is connected to the cleaning robot. The drive gear 221 is disposed on the connecting seat 223. The input end of the drive gear 221 is connected to the drive motor 210. The output end of the drive gear 221 is connected to the coupling 222. The coupling 222 is connected to the first turntable 110 in a transmission connection.

[0049] The connecting seat 223 can be fixedly installed on the bottom of the cleaning robot by means of screws, clips, etc. The connecting seat 223 can be a shell structure with a first through hole 202. One end of the coupling 222 can pass through the first through hole 202 on the connecting seat 223 and be connected to the first turntable 110 for transmission.

[0050] The two ends of the coupling 222 can be connected to the output end of the drive gear 221 and the first turntable 110, respectively. For example, the cross-section of the rod portion of the coupling 222 can be square, and the center of the first turntable 110 has a mounting groove that matches the cross-sectional shape of the rod portion of the coupling 222. After the rod portion of the coupling 222 is inserted into the mounting groove on the first turntable 110, the coupling 222 and the first turntable 110 are connected in a transmission manner. When the input end of the drive gear 221 is connected in a transmission manner to the output shaft of the drive motor 210, the drive motor 210 drives the coupling 222 to rotate through the drive gear 221, thereby driving the first turntable 110 to rotate.

[0051] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the drive gear 221 includes a second gear 2211, a third gear 2212 and a fourth gear 2213, the second gear 2211 is connected to the output shaft of the drive motor 210 for transmission, the third gear 2212 is a double gear, the fourth gear 2213 is rotatably connected to the coupling 222, the large gear of the third gear 2212 meshes with the second gear 2211, and the small gear of the third gear 2212 meshes with the fourth gear 2213.

[0052] The second gear 2211 can be used to transmit power between the drive motor 210 and the third gear 2212. For example, the second gear 2211 can be a worm gear structure. After the shank of the second gear 2211 is connected to the drive motor 210, when the drive motor 210 is working, it can drive the second gear 2211 to rotate synchronously. The teeth of the second gear 2211 mesh with the third gear 2212, thereby driving the third gear 2212 to rotate. In addition, since the second gear 2211 is a worm gear structure, the drive motor 210 can be installed horizontally inside the cleaning robot, improving the rationality of the internal design of the cleaning robot and reducing the thickness of the cleaning robot.

[0053] The third gear 2212 can be a double gear structure. Specifically, the large gear portion and the small gear portion of the third gear 2212 form a second annular groove 201, which provides installation space for the fourth gear 2213. The fourth gear 2213 meshes with the small gear portion of the third gear 2212 within the second annular groove 201, while the large gear portion of the third gear 2212 meshes with the second gear 2211. When the second gear 2211 rotates, it drives the third gear 2212 to rotate, which in turn drives the fourth gear 2213 to rotate. Based on the connection between the coupling 222 and the fourth gear 2213, the connecting shaft rotates synchronously with the output shaft of the drive motor 210 under the drive of the fourth gear 2213. In addition, in some embodiments, the connecting seat 223 covers the second annular groove 201. Based on the above design, it is possible to prevent garbage, hair, debris, etc. from accidentally entering the gearbox and causing jamming or damage, thereby improving the stability and service life of the cleaning disc.

[0054] like Figures 2 to 4As shown, in addition to the features of the above embodiments, this embodiment further defines that: the coupling 222 includes a base 2221 and a drive shaft 2222, one end of the drive shaft 2222 is connected to the base 2221, and the other end is connected to the first turntable 110. The end of the base 2221 away from the drive shaft 2222 has a plurality of spaced limiting posts 22211. The number of fourth gears 2213 is the same as the number of limiting posts 22211, and the fourth gears 2213 are rotatably disposed on the plurality of limiting posts 22211.

[0055] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a pressure strip 400 is provided between the second turntable 120 and the second wiping cloth 320, and the pressure strip 400 is used to improve the adhesion between the second wiping cloth 320 and the wiping surface.

[0056] There is a gap between the second cloth 320 and the second turntable 120. The shape of this gap can be ring-shaped. The pressure strip 400 can be installed in the gap between the second cloth 320 and the second turntable 120. Correspondingly, the shape of the pressure strip 400 matches the shape of the gap and is also ring-shaped.

[0057] The pressure strip 400 is used to improve the adhesion between the second cloth 320 and the surface to be wiped. The pressure strip 400 can be an elastic structure, such as rubber, silicone, or a spring structure. Based on the design of the pressure strip 400, this embodiment allows the second cloth 320 to deform when encountering obstacles or uneven surfaces, thereby maintaining uniform contact pressure between the cloth and the surface. This ensures better adhesion to hard floors, carpets, windows, etc., resulting in superior cleaning performance. Furthermore, because the pressure strip 400 is an elastic structure, the cleaning pad reduces hard contact with the surface during operation, thereby reducing noise and providing a better user experience.

[0058] In addition to the features of the above embodiments, this embodiment further specifies that the first wiping cloth 310 and the first turntable 110 are detachably connected.

[0059] The first cleaning cloth 310 and the first turntable 110 can be detachably connected via Velcro, snap-fit, magnetic connection, or elastic clamping. This detachable connection facilitates the cleaning of the first cleaning cloth 310.

[0060] In addition to the features of the above embodiments, this embodiment further specifies that the second cloth 320 and the second turntable 120 are detachably connected.

[0061] The second cleaning cloth 320 and the second turntable 120 can be detachably connected via Velcro, snap-fit, magnetic connection, or elastic clamping. This detachable connection facilitates the cleaning of the second cleaning cloth 320.

[0062] like Figure 1 and Figure 2 As shown, this embodiment provides a cleaning robot, which includes the cleaning pad described above.

[0063] It should be noted that the cleaning robot in this application can be a sweeping robot for floor cleaning or a window cleaning robot for wiping glass. Furthermore, the drive motor 210 and the first transmission module 220 in the cleaning disc can be installed in the internal cavity of the cleaning robot.

[0064] In addition to the features of the above embodiments, this embodiment further specifies that: the number of cleaning pads is not less than two, and not less than two cleaning pads are arranged at the bottom of the cleaning robot.

[0065] The number of cleaning pads can be at least two. For example, two cleaning pads can be spaced apart along the length of the bottom of the cleaning robot. It should also be noted that the number of cleaning pads can also be three, four, five, etc., depending on the actual cleaning task requirements.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
