Description

Technical Field

[0001] The present invention relates to cleaning equipment, and more particularly to a cleaning assembly and a cleaning device. Background Art

[0002] With the improvement of living standards, people's requirements for the quality of life are getting higher and higher. Environmental hygiene is an important indicator to measure the quality of life. However, modern people's work pressure is increasing day by day, and they don't have much time to clean the home environment. In order to liberate people from the heavy cleaning work, many cleaning devices have emerged, such as vacuum cleaners and floor washers.

[0003] However, in the existing cleaning devices, there is usually a certain distance between the edge of the cleaning assembly and the edge of the body of the cleaning device, so that the area corresponding to this distance is ignored during the cleaning process and cannot be cleaned. Especially when performing edge cleaning, the cleaning assembly cannot wipe the ground near the wall, which will affect the cleaning effect of the cleaning device. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the present invention provides a cleaning assembly and a cleaning device to improve the cleaning effect of the cleaning assembly.

[0005] To achieve the above object and other related objects, in a first aspect of the present invention, a cleaning assembly is provided. The cleaning assembly includes: a first connector, a second connector, a cleaning mechanism, a translation mechanism, and a lifting mechanism; the second connector is slidably installed on the first connector; the cleaning mechanism is linked and cooperated with the second connector and has an expanded position and a retracted position relative to the first connector; the translation mechanism is used to drive the second connector to slide horizontally relative to the first connector, so as to drive the cleaning mechanism to move horizontally by using the second connector, so that the cleaning mechanism is in the expanded position or the retracted position; during the process of the second connector sliding relative to the first connector, the lifting mechanism is used to drive the cleaning mechanism to perform a lifting movement in the height direction.

[0006] In an embodiment of the present invention, the lifting mechanism includes a lifting surface and a holding portion. The lifting surface has an inclined surface. The holding portion is connected to the cleaning mechanism. The lifting surface is arranged on the second connector, and the holding portion can move along the lifting surface to drive the cleaning mechanism to perform a lifting movement in the height direction.

[0007] In an embodiment of the present invention, the lifting surface further includes a first plane and a second plane. The first plane and the second plane are respectively connected to both ends of the inclined surface in the inclined direction, and the distance from the first plane to the ground is less than the distance from the second plane to the ground. When the cleaning mechanism is in the lifted position, the holding portion stays on the second plane. When the cleaning mechanism is in the lowered position, the holding portion stays on the first plane.

[0008] In one embodiment of the present invention, the translation mechanism includes a second through groove and a connecting assembly, the second through groove is arranged on the first connecting member, and the extension direction of the second through groove is consistent with the sliding direction of the second connecting member; the cleaning mechanism is connected to the second connecting member through the connecting assembly, and the connecting assembly is slidably connected to the second through groove.

[0009] In one embodiment of the present invention, the connecting assembly includes an extension portion, one end of which is connected to the side of the cleaning mechanism facing the first connecting member, and the bottom wall of the second connecting member is provided with a first through groove, and the extension portion passes through the second through groove and the first through groove in sequence and is connected to the supporting portion.

[0010] In one embodiment of the present invention, along the height direction of the second connecting member, the second connecting member is provided with a shielding portion on the side of the first through slot away from the cleaning mechanism, the shielding portion is located above the first plane, and the shielding portion is used to shield the extension portion to limit the maximum upward movement stroke of the cleaning mechanism.

[0011] In one embodiment of the present invention, a second groove is provided on the side of the shielding portion facing the extension portion, and a protrusion matching the second groove is provided on the side of the extension portion facing the shielding portion. When the cleaning mechanism is in the falling position, the protrusion can be correspondingly inserted into the second groove.

[0012] In one embodiment of the present invention, an escape slope is provided at the end of the shielding portion facing the second plane, and when the supporting portion moves from the first plane to the second plane, the escape slope can form an escape space on the moving path of the extending portion.

[0013] In one embodiment of the present invention, the inclined surface is provided with a protruding slide bar, the length direction of the slide bar is consistent with the extension direction of the inclined surface, and the abutting portion abuts against the slide bar.

[0014] In one embodiment of the present invention, a second guide assembly is provided between the first connecting member and the second connecting member to guide the second connecting member to slide along the first connecting member.

[0015] In one embodiment of the present invention, the second guide assembly includes a sliding cavity and a second sliding portion, the sliding cavity is arranged on the first connecting member, and the bottom wall of the sliding cavity is provided with a second through groove; the second sliding portion is arranged on the second connecting member; the second connecting member is slidably connected to the sliding cavity through the second sliding portion.

[0016] In one embodiment of the present invention, a driving component is disposed between the first connecting member and the second connecting member, and the driving component is used to drive the second connecting member to slide relative to the first connecting member.

[0017] In an embodiment of the present invention, the driving assembly includes a second driving member, a third gear, and a rack meshing with the third gear. The rack is disposed on a second connecting member, and the second driving member is disposed on a first connecting member; the second driving member is configured to drive the third gear to rotate, and the rotation of the third gear drives the rack to move, so as to drive the second connecting member to slide.

[0018] In an embodiment of the present invention, the driving assembly further includes a transmission shaft rotatably mounted on the first connecting member. The third gear is coaxially mounted on the transmission shaft, and the second driving member drives the transmission shaft to rotate through a bevel gear structure. The output shaft of the second driving member is perpendicular to the transmission shaft.

[0019] The second aspect of the present invention is to provide a cleaning device, which includes the cleaning assembly in any of the above embodiments.

[0020] Advantages of the present application: By providing a translation mechanism, when the second connecting member slides relative to the first connecting member, the translation mechanism can drive the cleaning mechanism to move horizontally, so that the cleaning mechanism can be switched between an extended position and a retracted position. With this arrangement, when the cleaning device is performing normal cleaning operations (without cleaning the corners), the cleaning member only needs to be in the retracted position to clean the surface to be cleaned. This can reduce the area of the cleaning member extending outside the body of the device, thereby reducing the probability of accidental damage to the cleaning mechanism caused by external force collision and friction. Therefore, it is more suitable for operating in complex environments, such as scenarios where frequent movement or cleaning operations in narrow spaces are required. When the cleaning device needs to clean the corners of the surface to be cleaned, the cleaning member can move from the retracted position to the extended position, thereby achieving effective cleaning of the corner area of the cleaning device, and further improving the cleaning effect of the cleaning device on the corners.

[0193] Please refer to Figures 1 to 88 , the present invention provides a cleaning assembly 100 and a cleaning device 1000. Through the collaborative design of the bracket assembly 120, the pulling member 130, and the outer support assembly 140, the cleaning member 110 of the cleaning assembly 100 can be quickly switched between the tensioned state and the relaxed state. Therefore, the replacement efficiency of the cleaning member 110 can be improved, and the cleaning efficiency of the cleaning device 1000 can be enhanced.

[0194] The cleaning device 1000 provided by the embodiments of the present invention can be a self - moving cleaning robot or a handheld floor washer. The self - moving cleaning robot can be a mopping robot, a sweeping and mopping integrated robot, etc.

[0195] In the following embodiments, taking the cleaning device 1000 as a self - moving cleaning robot as an example, some of its components are introduced. However, those skilled in the art can understand that on other robots including the cleaning assembly 100 of the present invention, the beneficial effects brought by the cleaning assembly 100 of the present invention can also be achieved.

[0196] Please refer to Figure 1, the cleaning device 1000 has a body 200, and various components of the cleaning device 1000 can be accommodated inside the body 200. The outer shape of the body 200 can be any shape, such as a cylindrical shape, an oval shape, or a D-shaped shape, etc.

[0197] The cleaning device 1000 further includes a traveling system conventionally provided on the existing cleaning device 1000, which is used to drive the body 200 to move automatically to achieve the self-moving traveling function on the surface to be cleaned. The traveling system at least includes a driver and driving wheels 240. Under the action of the driver, the driving wheels 240 rotate. Generally, there can be two driving wheels 240, and the two driving wheels 240 are symmetrically arranged at the bottom of the body 200. The specific structure of the traveling system and the connection structure between the traveling system and the body 200 can refer to the relevant structures described in the existing cleaning device 1000, and will not be elaborated here.

[0198] To exert the cleaning function of the cleaning device 1000, the cleaning device 1000 at least includes a cleaning assembly 100. The cleaning assembly 100 is detachably connected to the body 200, and the detachable connection method can be snap detachable connection, bolt detachable connection, etc. The cleaning assembly 100 can be configured for dry mopping or wet mopping. Optionally, in this embodiment, the cleaning assembly 100 is configured for wet mopping.

[0199] Optionally, in an embodiment, please refer to Figures 1 to 3 , the cleaning device 1000 may further include side brushes 210 and a rotary brush 220, and the side brushes 210 and the rotary brush 220 are arranged at the bottom of the body 200. Along the traveling direction of the body 200, that is, Figure 2 the arrow W1 direction shown in, both the side brushes 210 and the rotary brush 220 are located in front of the cleaning assembly 100. Among them, the side brushes 210 can be arranged at the edges of the body 200, and the side brushes 210 can perform rotational movement through a rotating mechanism. The rotating mechanism can be a motor, a combination of a motor and a speed reducer, etc. When the side brushes 210 rotate, they can gather the garbage at the edge position of the body 200 towards the inside of the body 200, thereby increasing the cleaning range of the cleaning device 1000. The side brushes 210 can be rubber strips or brushes, etc., as long as they can clean the ground, and are not limited here. The rotary brush 220 is rotatably arranged in a rotary brush cavity at the bottom of the body 200. The rotary brush 220 can clean the garbage on the ground during the rolling process. The number of the rotary brushes 220 can be set according to specific requirements and is not limited in this embodiment.

[0200] Along the traveling direction of the body 200, arranging the side brushes 210 and the rotary brush 220 in front of the cleaning assembly 100 facilitates the cleaning operation of the cleaning device 1000 to first dry sweep and then wet mop, and also facilitates the layout of the internal space of the body 200.

[0201] In addition, the cleaning device 1000 may further include a sensing system and a control system. The sensing system is electrically connected to the control system. The sensing system includes an LDS located above the body 200, a buffer and a vision sensor located at the front of the body 200, and a border sensor located on the side wall of the front of the body 200, etc. Among them, the LDS, the buffer, and the border sensor can all measure or sense the distance to obtain the distance between the edge of the body 200 and the obstacle, and the control system controls the cleaning device 1000 to perform corresponding actions according to this distance. For example, controlling the cleaning device 1000 to perform obstacle avoidance, edge cleaning, returning to the base station and other actions.

[0202] For the cleaning assembly 100, there can be various ways for the cleaning assembly 100. Optionally, in this embodiment, please refer to Figures 3 to 12 , the cleaning assembly 100 includes: a cleaning member 110, a bracket assembly 120, a pulling member 130, and an outer support assembly 140.

[0203] The cleaning member 110 can be made of fiber cloth, sponge, rubber material, etc., and the cleaning member 110 is wound around the bracket assembly 120. The winding shape of the cleaning member 110 on the bracket assembly 120 can be in various ways such as planar shape, annular shape, etc. Exemplarily, please refer to Figure 4 and Figure 7 , in this embodiment, the cleaning member 110 is wound around the outer periphery of the bracket assembly 120 in a shape similar to an annular runway to form a structure similar to a crawler belt.

[0204] Please refer to Fig. 9 , Fig.10 and Fig.13 , the bracket assembly 120 includes a bracket body, and the bracket body includes a first bracket 121 and a second bracket 122. The cleaning member 110 is wound around the first bracket 121 and the second bracket 122 and is supported by the first bracket 121 and the second bracket 122. The pulling member 130 is arranged between the first bracket 121 and the second bracket 122. The pulling member 130 has a pulling force that makes the first bracket 121 and the second bracket 122 approach each other. Specifically, when the first bracket 121 and the second bracket 122 are separated from each other, the pulling member 130 is stretched, and the pulling force of the pulling member 130 increases so that the first bracket 121 and the second bracket 122 have a reset pulling force to approach each other. When the first bracket 121 and the second bracket 122 are close to each other, the pulling member 130 also has a pulling force at this time, and this pulling force 130 is used to make the first bracket 121 and the second bracket 122 fit together and not separate. The pulling member 130 can be a tension spring, an elastic band, or a combination of a rope and a pulley structure, etc., as long as it can generate a pulling force that makes the first bracket 121 and the second bracket 122 approach each other.

[0205] In other embodiments, it can also be that when the first bracket 121 and the second bracket 122 are separated from each other, the pulling member 130 has a pulling force that causes the first bracket 121 and the second bracket 122 to approach each other. When the first bracket 121 and the second bracket 122 are attached to each other, the pulling member 130 does not deform and does not generate a pulling force.

[0206] Under the condition of meeting the pulling requirements between the first bracket 121 and the second bracket 122, one pulling member 130 can be provided, or two or more pulling members 130 can be provided. Optionally, in order to achieve the uniformity of the pulling force of the first bracket 121 and the second bracket 122 in the length direction, in this embodiment, please refer to Fig. 9 and Fig.10 , two pulling members 130 are provided, and the two pulling members 130 are respectively arranged near both ends of the bracket assembly 120 in the length direction.

[0207] Please refer to Fig.13 , Fig.14 and Fig.17 , the outer support assembly 140 is slidably disposed between the first bracket 121 and the second bracket 122. When the outer support assembly 140 slides between the first bracket 121 and the second bracket 122, the first bracket 121 and the second bracket 122 are pushed apart to both sides. The outer support assembly 140 can be an integral part, and by sliding the integral part into the space between the first bracket 121 and the second bracket 122, the first bracket 121 and the second bracket 122 are pushed apart to both sides. The outer support assembly 140 can also be multiple parts, and only some parts are slid into the space between the first bracket 121 and the second bracket 122 to achieve the relative separation of the first bracket 121 and the second bracket 122. The sliding insertion path of the outer support assembly 140 can be a straight line, a curve or other specific shapes, and the outer support assembly 140 has at least a first position and a second position on the sliding path.

[0208] As Fig.15 shown, when the outer support assembly 140 is in the first position, the outer support assembly 140 makes the first bracket 121 and the second bracket 122 have a first spacing that causes the cleaning member 110 to be tensioned. As Fig.17 shown, when the outer support assembly 140 is in the second position, the pulling force of the pulling member 130 makes the first bracket 121 and the second bracket 122 have a second spacing that causes the cleaning member 110 to be relaxed. The specific sizes of the first spacing and the second spacing are not limited. In the actual design and production process, they need to be determined according to the size of the cleaning member 110.

[0209] By arranging an outer support assembly 140 and a pulling member 130 between a first bracket 121 and a second bracket 122, and enabling the pulling member 130 to have a pulling force that causes the first bracket 121 and the second bracket 122 to approach each other, and the outer support assembly 140 slides between a first position and a second position. With such an arrangement, when the cleaning member 110 needs to be tensioned, the outer support assembly 140 is slid to the first position, and a first distance can be formed between the first bracket 121 and the second bracket 122, thereby realizing the tensioning of the cleaning member 110. In the tensioned state, the cleaning member 110 can better fit the surface to be cleaned, improving the cleaning effect. When the cleaning member needs to be switched to the relaxed state, the outer support assembly 140 is slid to the second position, and the first bracket 121 and the second bracket 122 approach each other under the action of the pulling force, and then a second distance is formed between the first bracket 121 and the second bracket 122 to realize the relaxation of the cleaning member 110. In the relaxed state, it is more conducive to the storage and replacement of the cleaning member 110. It should be noted that the so-called approaching each other here means that the first bracket 121 and the second bracket 122 can be in contact with each other, or can have other distances smaller than the first distance, that is, the distance range between the first bracket 121 and the second bracket 122 is greater than or equal to zero and less than the first distance. The following related content is the same as the description here. Therefore, through the synergistic effect of the outer support assembly 140 and the pulling member 130, the cleaning assembly 100 can realize the rapid switching between the tensioned state and the relaxed state of the cleaning member 110, and further can simplify the replacement operation steps of the cleaning assembly 100, shorten the replacement operation time, thereby improving the replacement efficiency of the cleaning assembly 100 and the cleaning efficiency of the cleaning device 1000. Moreover, when the cleaning assembly 100 of the present invention is in the tensioned state, it realizes rigid tensioning through the outer support assembly 140, and has higher tensioning stability compared with the tensioning realized by elastic components such as compression springs, and can prevent local torsion or misalignment of the cleaning member 110 caused by non-constant tension force.

[0210] To improve the sliding accuracy between the first bracket 121 and the second bracket 122 and reduce the jamming phenomenon during sliding, optionally, please refer to Fig.14 、 Fig.18 and Fig. 20In one embodiment of the present invention, a first guide assembly 150 is provided between the first bracket 121 and the second bracket 122, and the first guide assembly 150 is used to guide the first bracket 121 and the second bracket 122 to slide along the direction of the pulling force. There are many specific structures of the first guide assembly 150, for example, it can be a guide rail and slider structure, a slide groove and slider structure, a guide rod and guide sleeve structure and other structures with a guiding function. By providing the first guide assembly 150, the first guide assembly 150 can ensure that the first bracket 121 and the second bracket 122 slide along a predetermined direction, reduce the probability of offset or shaking between each other during the sliding process, and thus improve the sliding accuracy between the first bracket 121 and the second bracket 122, reduce the jamming phenomenon during the sliding process, and help to improve the smoothness of the sliding between the first bracket 121 and the second bracket 122. At the same time, the first guide assembly 150 can also provide additional support for the first bracket 121 and the second bracket 122, which is conducive to enhancing the overall rigidity and stability of the bracket assembly 120.

[0211] Optionally, in one embodiment of the present invention, please refer to Fig.14 , Fig.18 and Fig. 20 The first guide assembly 150 includes an inserting portion 151 and a card slot 152, which are respectively arranged on opposite sides of the first bracket 121 and the second bracket 122. In the process of the first bracket 121 and the second bracket 122 approaching or separating from each other, the inserting portion 151 can be slidably inserted into the card slot 152. In this embodiment, the inserting portion 151 is arranged on the side of the second bracket 122 facing the first bracket 121, and the card slot 152 is arranged on the side of the first bracket 121 facing the second bracket 122.

[0212] In another embodiment, the plug-in portion 151 may be disposed on the side of the first bracket 121 facing the second bracket 122, and the card slot 152 may be disposed on the side of the second bracket 122 facing the first bracket 121. In other embodiments, the plug-in portion 151 may be partially disposed on the first bracket 121 and partially disposed on the second bracket 122. Correspondingly, the card slot 152 is partially disposed on the second bracket 122 to cooperate with a portion of the plug-in portion 151 disposed on the first bracket 121, and the card slot 152 is also partially disposed on the first bracket 121 to cooperate with a portion of the plug-in portion 151 disposed on the second bracket 122.

[0213] The plug-in portion 151 may be arranged along the length direction of the bracket assembly 120 (eg Fig.15 The bracket assembly 120 may be a long strip block structure (shown as the X-axis in the middle), or a plurality of protrusion structures may be arranged at intervals along the length direction of the bracket assembly 120. The shape of the card slot 152 matches the shape of the plug-in portion 151, so that the plug-in portion 151 can be inserted.

[0214] It should be noted that, due to the different mating structures of the insertion part 151 and the card slot 152, when the insertion part 151 is inserted into the card slot 152, the first bracket 121 and the second bracket 122 can be mutually limited in the height direction of the bracket assembly 120 (as shown by the Z-axis in Fig.16 ), to form a guiding effect, or can be mutually limited in the length direction of the bracket assembly 120 to form a guiding effect, or can also form a guiding effect in both the height direction and the length direction of the bracket assembly 120.

[0215] Specifically, in this embodiment, please refer to Fig.15 , Fig.17 , Fig.18 and Fig. 20 . The insertion part 151 is a long strip block structure. The insertion part 151 extends along the length direction of the second bracket 122 and generally covers the entire length direction of the second bracket 122. Correspondingly, the card slot 152 extends along the length direction of the first bracket 121 and generally covers the entire length direction of the first bracket 121. When the insertion part 151 is engaged with the card slot 152, in the height direction of the bracket assembly 120, the upper and lower side surfaces of the insertion part 151 respectively cooperate with the upper and lower side surfaces of the card slot 152 to form a abutting relationship during the insertion process, thereby forming a guiding effect along the height direction of the bracket assembly 120 between the first bracket 121 and the second bracket 122. It should be noted that the above "upper and lower side surfaces" are the two side surfaces of the card slot 152 or the insertion part 151 along the Fig.16 Z-axis direction in

[0216] By providing the insertion part 151 and the card slot 152, the cooperation between the insertion part 151 and the card slot 152 can make the sliding between the first bracket 121 and the second bracket 122 smoother, playing a role of sliding guidance. At the same time, due to the simple structural design of the insertion part 151 and the card slot 152 and easy implementation, it is beneficial to reduce the production and manufacturing costs.

[0217] Please refer to Fig.14 , Fig.18 , Fig. 20 and Fig.21 . In an embodiment of the present invention, the first guiding assembly 150 further includes a guiding groove 153 and a guiding rod 154. The guiding groove 153 and the guiding rod 154 are respectively arranged on the first bracket 121 and the second bracket 122. The guiding rod 154 is inserted into the guiding groove 153 and slides along the guiding groove 153 during the process of the first bracket 121 and the second bracket 122 approaching or separating from each other. The guiding groove 153 is a long groove structure extending along the sliding direction of the first bracket 121 and the second bracket 122. The cooperation between the guiding groove 153 and the guiding rod 154 defines the maximum distance between the first bracket 121 and the second bracket 122, and this maximum distance is greater than or equal to the first distance.

[0218] The number of the guiding grooves 153 and the guiding rods 154 is not limited, and can be one or multiple. One guiding groove 153 can correspond to one guiding rod 154, or one guiding groove 153 can also correspond to multiple guiding rods 154. Optionally, please refer to Fig.13 , in this embodiment, along the length direction of the bracket assembly 120, two guiding grooves 153 and two guiding rods 154 are arranged at intervals, and one guiding rod 154 is inserted into one guiding groove 153 correspondingly.

[0219] Specifically, please refer to Fig.18 、 Fig. 20 and Fig.21 , in this embodiment, the two guiding grooves 153 are arranged on the second bracket 122 and located on the insertion part 151. The two guiding rods 154 are arranged on the first bracket 121 and connected to the groove wall of the card slot 152. In another embodiment, it can also be that the two guiding grooves 153 are arranged on the first bracket 121 and the two guiding rods 154 are arranged on the second bracket 122. In other embodiments, it can also be that the two guiding grooves 153 are respectively arranged on the first bracket 121 and the second bracket 122, and the two guiding rods 154 are respectively arranged corresponding to the first bracket 121 and the second bracket 122.

[0220] By arranging the guiding groove 153 and the guiding rod 154, the guiding rod 154 slides in the guiding groove 153. On the one hand, it can limit the maximum separation distance (greater than or equal to the first distance) and the minimum approaching distance (i.e., the second distance) between the first bracket 121 and the second bracket 122, ensuring the consistency of the tension degree of the bracket assembly 120 on the cleaning part 110. At the same time, it can also limit the moving distance of the insertion part 151 in the card slot 152, and further ensure that at least part of the insertion part 151 is always located in the card slot 152, that is, when the first bracket 121 and the second bracket 122 are at the maximum separation distance, at least part of the insertion part 151 is always located in the card slot 152, which is beneficial to improving the smoothness of the sliding between the first bracket 121 and the second bracket 122. On the other hand, the mutual cooperation of the guiding groove 153 and the guiding rod 154 can also guide the mutual movement of the first bracket 121 and the second bracket 122, so as to further improve the guiding effect between the first bracket 121 and the second bracket 122 and ensure the sliding accuracy.

[0221] Considering the repeated position accuracy when the first bracket 121 and the second bracket 122 are mutually attached, optionally, please refer to Fig.14 and Fig.17, in an embodiment of the present invention, one side of the first bracket 121 facing the second bracket 122 includes a first docking portion 1211, and one side of the second bracket 122 facing the first bracket 121 includes a second docking portion 1221. When the first bracket 121 and the second bracket 122 are mutually attached, the first docking portion 1211 and the second docking portion 1221 are mutually docked to form a docking seam 123, and the docking seam 123 includes a bent section 1231. The docking seam 123 may be a continuous docking seam structure distributed along the length direction of the bracket assembly 120, or may be a structure of multiple intermittently distributed docking seams. Optionally, in this embodiment, the docking seam 123 is a continuous docking seam 123 structure distributed along the length direction of the bracket assembly 120, and the length of the docking seam 123 generally covers the entire length of the bracket assembly 120.

[0222] The bent section 1231 may be various bent structures such as an arc bend, a V-shaped bend, a wavy bend, etc. One bent section 1231 may be provided on the docking seam 123, or multiple bent sections 1231 may be provided. Optionally, please refer to Fig.14 , in this embodiment, multiple approximately trapezoidal bent sections 1231 are provided on the docking seam 123. Such a setting is beneficial to guiding the docking of the first bracket and the second bracket and forming a limit between the two. Compared with the straight seam docking structure, this structure has higher docking stability.

[0223] Specifically, in this embodiment, please refer to Fig.19 and Fig. 20 , on the side of the insertion portion 151 facing away from the card slot 152, a boss structure is formed, and the boss structure includes multiple first convex portions 1511 protruding toward the side of the card slot 152 and multiple first concave portions 1512 recessed on the side facing away from the card slot 152. On the edge of the wall body of the card slot 152 on the side facing away from the insertion portion 151, multiple second concave portions 1522 and multiple second convex portions 1521 are correspondingly provided. The second concave portions 1522 are correspondingly matched with the first convex portions 1511, and the second convex portions 1521 are correspondingly matched with the first concave portions 1512. When the first docking portion 1211 and the second docking portion 1221 are mutually docked, the first concave portion 1512 and the second convex portion 1521 are docked, and the first convex portion 1511 and the second concave portion 1522 are docked, thereby forming a docking seam 123 having a bent section 1231.

[0224] Since the seam 123 includes a bent section 1231, when the first docking portion 1211 is docked with the second docking portion 1221, it can be in the length direction and width direction of the bracket assembly 120 (such as Fig.15Positioning is simultaneously achieved on the Y-axis (as shown). This design ensures that the first bracket 121 and the second bracket 122 can be accurately docked along a predetermined direction, reducing the possibility of the first bracket 121 and the second bracket 122 shifting or shaking during the docking process, thereby improving the docking accuracy when the first bracket 121 and the second bracket 122 are in contact with each other, and ensuring the repeat position accuracy when they are in contact.

[0225] Although the pulling member 130 can have various structures, considering the manufacturing cost and structural complexity of the pulling member 130, optionally, in an embodiment of the present invention, please refer to Fig. 9 and Fig.10 , the pulling member 130 is an elastic member, and both ends of the elastic member are respectively connected to the first bracket 121 and the second bracket 122. The elastic force generated by the elastic member forms a pulling force. The elastic member can be a tension spring, an elastic band, a rubber cord, or any other elastic member that can generate a pulling force when the first bracket 121 and the second bracket 122 approach each other. By setting the pulling member 130 as an elastic member, the first bracket 121 and the second bracket 122 are automatically pulled back to the approximate state by the elastic force of the elastic member, realizing the automatic approach between the first bracket 121 and the second bracket 122. This can reduce manual intervention and save the complexity of the operation. At the same time, the presence of the elastic member also enables the first bracket 121 and the second bracket 122 to maintain a certain elastic connection when they are separated from each other, avoiding structural looseness or out-of-control, and improving the overall stability of the bracket assembly 120. In addition, the structure of the elastic member is relatively simple, and no additional components need to be provided, so the installation is also relatively convenient, and the procurement and manufacturing costs will be correspondingly reduced.

[0226] Under the condition that the pulling member 130 is an elastic member, optionally, in an embodiment of the present invention, please refer to Fig. 9 , Fig.10 , Fig.11 and Fig.70, the elastic member is a tension spring. The two ends of the tension spring are respectively connected to the first bracket 121 and the second bracket 122, and the spring force generated by the tension spring forms a pulling force. The installation positions of the tension spring on the first bracket 121 and the second bracket 122 are not limited. For example, the tension spring can be arranged in the area where the first bracket 121 and the second bracket 122 do not have the insertion part 151 and the card slot 152, or can be arranged between the insertion part 151 and the card slot 152. The telescopic direction of the tension spring is consistent with the sliding direction of the first bracket 121 and the second bracket 122. It should be noted that when the first bracket 121 and the second bracket 122 are in the fitting position, at this time, the tension spring still needs to have a certain spring force so as to still be able to generate a certain pulling force on the first bracket 121 and the second bracket 122 at the mutual fitting position. Since the tension spring is usually a standard part, it is convenient to purchase, and there are many selectable specifications and models, which is beneficial to design selection. And the installation of the tension spring is relatively convenient, occupies less space, and is beneficial to the compact design of the structure.

[0227] Please refer to Fig.21 、 Fig. 22 and Fig.25 , in an embodiment of the present invention, mounting cavities 124 are provided on the first bracket 121 and the second bracket 122, and the tension spring is arranged in the mounting cavities 124. The mounting cavities 124 can be partially arranged on the insertion part 151 of the first bracket 121 and partially arranged in the card slot 152 of the second bracket 122. The shape of the mounting cavities 124 can be various shapes such as a cuboid or a cylinder that can accommodate the tension spring. In another embodiment, the mounting cavities 124 can also be only arranged on the insertion part 151 of the first bracket 121. In other embodiments, the mounting cavities 124 can also be only arranged in the card slot 152 of the second bracket 122. By providing the mounting cavities 124, a protective effect can be formed on the tension spring, reducing the probability that impurities or particulate matter fall onto the tension spring and cause the tension spring to have telescopic jams.

[0228] Specifically, please refer to Fig.21 、 Fig. 22 and Fig.25, in this embodiment, the first bracket 121 is provided with a first mounting cavity 1241, and the opening of the first mounting cavity 1241 faces the second bracket 122. The second bracket 122 is provided with a second mounting cavity 1242, and the opening of the second mounting cavity 1242 faces the first bracket 121. The first mounting cavity 1241 and the second mounting cavity 1242 are coaxially arranged, and the outer diameter of the second mounting cavity 1242 is less than or equal to the inner diameter of the first mounting cavity 1241, so that the second mounting cavity 1242 can be inserted into the first mounting cavity 1241. The first bracket 121 is provided with a first connecting column 131, and the first connecting column 131 penetrates through the first mounting cavity 1241 along the radial direction of the first mounting cavity 1241. The second bracket 122 is provided with a second connecting column 132, and the second connecting column 132 penetrates through the second mounting cavity 1242 along the radial direction of the second mounting cavity 1242. One end of the tension spring is located in the first mounting cavity 1241 and is hooked on the first connecting column 131, and the other end of the tension spring is located in the second mounting cavity 1242 and is hooked on the second connecting column 132.

[0229] The outer support assembly 140 is arranged between the first bracket 121 and the second bracket 122 to realize the change of the distance between the first bracket 121 and the second bracket 122. There can be various structural forms of the outer support assembly 140. Optionally, please refer to Fig.14 and Fig.17 , in an embodiment of the present invention, the outer support assembly 140 includes a seat body 141 and a first outer support member 142. Along the length direction of the bracket assembly 120, one end of the first bracket 121 and one end of the second bracket 122 are both inserted into the seat body 141. There can be various insertion methods. For example, columnar protrusions can be provided at the ends of the first bracket 121 and the second bracket 122, and corresponding insertion holes are provided on the seat body 141, and the columnar protrusions can be correspondingly inserted into the insertion holes to realize the insertion between each other. It can also be that insertion holes are provided at the ends of the first bracket 121 and the second bracket 122, and corresponding columnar protrusions are provided on the seat body 141, and the columnar protrusions can be correspondingly inserted into the insertion holes, and in this way, the insertion between each other can also be realized.

[0230] The first outer support member 142 is disposed at one end of the first support bracket 121 and the second support bracket 122 away from the seat body 141, and can be slidably inserted between the first support bracket 121 and the second support bracket 122 to realize the mutual separation of the first support bracket 121 and the second support bracket 122, so as to form a first spacing between the first support bracket and the second support bracket to tension the cleaning member. At the same time, the first connecting column 131 and the second connecting column 132 move away from each other, the tension spring is stretched, stores energy and generates a resilience force. Correspondingly, when the first outer support member 142 slides out from between the first support bracket 121 and the second support bracket 122, under the action of the resilience force of the tension spring, the first connecting column 131 and the second connecting column 132 move closer to each other, and then drive the first support bracket 121 and the second support bracket 122 to move closer to each other, so as to form a second spacing between the first support bracket 121 and the second support bracket 122 to relax the cleaning member 110. The first outer support member 142 can be of various structures such as a wedge structure, a cylindrical shape, a strip shape, etc., as long as when the first outer support member 142 is slidably inserted between the first support bracket 121 and the second support bracket 122, it can gradually expand the first support bracket 121 and the second support bracket 122, so that the spacing between the first support bracket 121 and the second support bracket 122 gradually increases to the second spacing.

[0231] By setting the outer support assembly 140 into two parts, namely the seat body 141 and the first outer support member 142, a split design of the support part and the movable part of the outer support assembly 140 can be realized. Since one end of the first support bracket 121 and one end of the second support bracket 122 are both inserted into the seat body 141, the seat body 141 needs to support the first support bracket 121 and the second support bracket 122, which is equivalent to the support part of the outer support assembly 140. Therefore, the seat body 141 needs to have a relatively high support strength in design to provide stable support for the first support bracket 121 and the second support bracket 122. And since the first outer support member 142 needs to slide between the first support bracket 121 and the second support bracket 122 to realize the mutual separation or mutual approach of the first support bracket 121 and the second support bracket 122, therefore, the first outer support member 142 is equivalent to the movable part of the outer support assembly 140. So, more sliding factors need to be considered in the design of the first outer support member 142 to be able to slide smoothly between the first support bracket 121 and the second support bracket 122. Therefore, the split design of the fixed part and the movable part can facilitate the flexible design of each part and is more conducive to the structural optimization of the outer support assembly 140.

[0232] To further enhance the support strength of the outer support assembly 140 for the first support bracket 121 and the second support bracket 122, optionally, please refer to Figure 7 、 Figure 8And, in an embodiment of the present invention, the outer support assembly 140 further includes a housing 180 disposed above the cleaning member 110. The housing 180 covers the cleaning member 110. One end of the housing 180 is connected to the seat body 141, and the other end of the housing 180 extends along the length direction of the bracket assembly 120 and covers the entire length of the cleaning member 110. A receiving cavity 190 is formed by enclosing the housing 180 and the seat body 141. An opening 191 is provided at one end of the receiving cavity 190 away from the seat body 141. The bracket assembly 120 and the cleaning member 110 are installed into the receiving cavity 190 from the opening 191, and one end of the bracket assembly 120 seals the opening 191.

[0233] Specifically, in this embodiment, please refer to Fig.17 and Fig.18 , the first bracket 121 includes a housing connection portion 1212 and a bracket main body 1213. The bracket main body 1213 is disposed opposite to the second bracket 122 and is used to cooperate with the second bracket 122 to support the wound cleaning member 110. One end of the second bracket 122 away from the seat body 141 is slidably connected to the housing connection portion 1212. The housing connection portion 1212 seals the opening 191 of the receiving cavity 190 and is detachably connected to the housing 180. The detachable connection methods include snap connection, bolt detachable connection, etc. In this embodiment, in order to facilitate the disassembly and assembly between the bracket assembly 120 and the housing 180, the housing connection portion 1212 is snap-connected to the housing 180.

[0234] In another embodiment, it may also be that the second bracket 122 is provided with a housing connection portion 1212, the first bracket 121 is slidably connected to the housing connection portion 1212, and the housing connection portion 1212 is connected to the housing 180. Similarly, the connection between the first bracket 121 and the second bracket 122 and the housing 180 can also be achieved. In other embodiments, it may also be that the first bracket 121 and the second bracket 122 are respectively provided with a housing connection portion 1212, and the first bracket 121 and the second bracket 122 are respectively connected to the housing 180 through their own housing connection portions 1212 to achieve the connection between the first bracket 121 and the second bracket 122 and the housing 180.

[0235] By providing the housing 180, the receiving cavity 190 formed by the cooperation of the housing 180 and the seat body 141 can provide a protective effect on the cleaning member 110, prevent the cleaning member 110 from being damaged by external forces during operation, and is beneficial to extending the service life of the cleaning member 110. At the same time, since the two ends of the housing 180 are respectively connected to the seat body 141 and the first bracket 121 and the second bracket 122, the support strength of the first bracket 121 and the second bracket 122 can be effectively improved, which is beneficial to improving the stability of the cleaning operation of the cleaning assembly 100.

[0236] Due to the tensile force that causes the first bracket 121 and the second bracket 122 to approach each other, when the first outer support member 142 slides between the first bracket 121 and the second bracket 122, it will also be subjected to the extrusion force of the first bracket 121 and the second bracket 122. To prevent the first outer support member 142 from sliding out between the first bracket 121 and the second bracket 122 under the action of the extrusion force and ensure the stability of the support of the bracket assembly 120 for the cleaning member 110, optionally, in an embodiment of the present invention, please refer to Figure 32 to Figure 36 , a first clamping portion 1801 is provided at one end of the housing 180 away from the seat body 141. The first clamping portion 1801 can be a groove structure, a protrusion structure, etc. The first outer support member 142 includes an inner support arm 1422, a second clamping portion 1423, and an end cover 1424. The inner support arm 1422 and the second clamping portion 1423 are both connected to the end cover 1424. The second clamping portion 1423 can be an elastic buckle structure that matches the first clamping portion 1801. One end of the inner support arm 1422 away from the end cover 1424 can be slidably inserted between the first bracket 121 and the second bracket 122 to achieve the mutual separation between the first bracket 121 and the second bracket 122. When the distance between the first bracket 121 and the second bracket 122 is the second distance, the first clamping portion 1801 and the second clamping portion 1423 can be clamped and fixed to each other.

[0237] By providing the first clamping portion 1801 and the second clamping portion 1802, when the first clamping portion 1801 and the second clamping portion 1423 are clamped and fixed to each other, not only can the relative fixed installation between the first outer support member 142 and the housing connection portion 1212 be achieved, but also the fixed connection between the bracket assembly 120 and the housing 180 can be achieved.

[0238] Specifically, in this embodiment, please refer to Figure 35 to Figure 39, the housing connection part 1212 is provided with a through snap groove 1215. A baffle 1216 is arranged in the snap groove 1215. The baffle 1216 divides the snap groove 1215 into a first hole 12151 and a second hole 12152. The first hole 12151 communicates with the receiving cavity 190. On the side of the housing 180 away from the cleaning part 110, an avoidance groove 1802 is provided. The first engaging part 1801 is arranged in the avoidance groove 1802. The second hole 12152 communicates with the avoidance groove 1802. When the first outer support part 142 is inserted into the snap groove 1215, the inner support arm 1422 is inserted from the first hole 12151 between the first bracket 121 and the second bracket 122 to separate the first bracket 121 and the second bracket 122. The second engaging part 1423 is inserted into the avoidance groove 1802 from the second hole 12152 and engages with the first engaging part 1801 in the avoidance groove 1802, thereby restricting the first outer support part 142 from moving outward of the snap groove 1215. The end cover 1424 is correspondingly snapped into the snap groove 1215. The baffle 1216 stops the end cover 1424 along the depth direction of the snap groove 1215 to restrict the end cover 1424 from continuing to enter the inside of the snap groove 1215, so as to limit the insertion depth of the first outer support part 142 between the first bracket 121 and the second bracket 122.

[0239] Under the condition of meeting the engagement requirements of the first engaging part 1801 and the second engaging part 1423, there is no limit to the specific engaging structure of the first engaging part 1801 and the second engaging part 1423. For example, it can be a hook-and-buckle engaging structure. The first engaging part 1801 is set as a hook, and the second engaging part 1423 is set as a corresponding groove or hole, and the engagement is realized by the hook being snapped into the groove or hole. It can also be a matching structure of a protrusion and a groove. The first engaging part 1802 is set as a protrusion, and the second engaging part 1423 is set as a corresponding groove, and the engagement is realized by the cooperation of the protrusion and the groove. Optionally, please refer to Figure 33 to Figure 36 , in this embodiment, the first engaging part 1801 includes a first buckle 18011, and the second engaging part 1423 includes a second buckle 14231. Along the sliding direction of the first outer support part 142, the opening of the first buckle 18011 faces away from the side of the snap groove 1215, and the opening of the second buckle 14231 faces the side close to the snap groove 1215. The end cover 1424 can move along the direction in which the first bracket 121 and the second bracket 122 move relative to each other in the snap groove 1215 (such as Fig.35It slides in the direction shown by W3 in the figure. In this sliding direction, the end cover 1424 has a first installation position and a second installation position in the snap groove 1215. When the end cover 1424 is in the first installation position, the first snap 18011 and the second snap 14231 are disengaged from each other in the direction of the relative movement between the first bracket 121 and the second bracket 122. At this time, the first outer support member 142 can move freely along the insertion direction. When the end cover 1424 is in the second installation position, the first snap 18011 and the second snap 14231 are engaged with each other, thereby restricting the movement of the first outer support member 142 towards the outside of the snap groove 1215. At the same time, with the restricting effect of the baffle 1216 in the snap groove 1215 on the movement of the end cover 1424 towards the inside of the snap groove 1215, the limit of the first outer support member 142 in the sliding direction can be achieved.

[0240] In some other embodiments, please refer to Figures 157 to 160 , a fifth snap 14203 is further provided on the first outer support member 142. Specifically, the fifth snap 14203 is provided on the inner support arm 1422 of the first outer support member 142, and a fourth snap 12122 that cooperates with the fifth snap 14203 is further provided at a position of the housing connection portion 1212 close to the first hole 12151. The engaging direction between the fifth snap 14203 and the fourth snap 12122 is the same as the sliding direction of the end cover 1424 in the snap groove 1215. When the end cover 1424 is in the first installation position, the fifth snap 14203 and the fourth snap 12122 are disengaged from each other. When the end cover 1424 is in the second installation position, the fifth snap 14203 and the fourth snap 12122 are engaged with each other, thereby further reducing the probability of the inner support arm 1422 slipping out of the first hole 12151, so as to further improve the stability of the outer support effect of the first outer support member 142 on the first bracket 121 and the second bracket 122.

[0241] With the above-mentioned snap connection structure, when the first outer support member 142 needs to be fixed after being inserted between the first bracket 121 and the second bracket 122, at this time, the end cover 1424 in the snap groove 1215 is slid from the first installation position to the second installation position, so that the first snap 18011 and the second snap 14231 are engaged with each other. On the contrary, when the first outer support member 142 needs to slide out from between the first bracket 121 and the second bracket 122, the end cover 1424 is slid in the reverse direction, so that the end cover 1424 slides from the second installation position to the first installation position, so that the first snap 18011 and the second snap 14231 are disengaged from each other, that is, the engaging relationship between the first snap 18011 and the second snap 14231 is released, and the free movement of the first outer support member 142 in the sliding direction is realized.

[0242] It should be noted that the number of the first buckle 18011 and the second buckle 14231 can be one or multiple, as long as the buckle strength requirement is met. Optionally, in this embodiment, the number of the first buckle 18011 and the second buckle 14231 is two each, and one first buckle 18011 corresponds to one second buckle 14231. Such a setting can form two clamping connection points when the first clamping portion 1801 and the second clamping portion 1423 are clamped with each other, thereby being beneficial to improving the clamping stability of the first outer support member 142 in the buckle groove 1215.

[0243] Optionally, in another embodiment, please refer to Fig.40 and Fig.41 , the first outer support member 142 may further include a first connecting portion 14201 and a second connecting portion 14202, and the first connecting portion 14201 and the second connecting portion 14202 are two independent split structures. The first connecting portion 14201 includes an inner support arm 1422 and a first end cover 14241, the second connecting portion 14202 includes a second clamping portion 1423 and a second end cover 14242, and the first end cover 14241 and the second end cover 14242 form the above-mentioned end cover 1424 after combination. When the first outer support member 142 needs to be inserted into the buckle groove 1215, the first connecting portion 14201 and the second connecting portion 14202 can be separately inserted into the buckle groove 1215. Such a setting can also achieve the clamping connection between the first outer support member 142 and the housing 180, and achieve the beneficial effects of the above embodiment.

[0244] Optionally, please refer to Fig.33 , Fig.35 and Fig.42 , in an embodiment of the present invention, the housing 180 includes a guiding wall 1803, the guiding wall 1803 is arranged in the avoidance groove 1802, and the guiding wall 1803 extends along the sliding direction of the first outer support member 142. The housing connecting portion 1212 further includes a guiding member 12121, the guiding member 12121 is inserted into the avoidance groove 1802 and is in fit with the guiding wall 1803. The number of the guiding walls 1803 is not limited, and can be one or two. Optionally, in this embodiment, there are two guiding walls 1803, and the two guiding walls 1803 are arranged oppositely along the length direction of the avoidance groove 1802. It should be noted that the length direction of the avoidance groove 1803 is the same as the moving direction of the first bracket 121 and the second bracket 122, as shown by the W4 direction in Fig.33 .

[0245] By providing the guiding member 12121 and the guiding wall 1803 and making the guiding member 12121 cooperate with the guiding wall 1803, a guiding effect can be achieved when the housing connecting portion 1212 is connected to the housing 180, facilitating the connection between the housing connecting portion 1212 and the housing 180, so as to facilitate the installation between the bracket assembly 120 and the housing 120. At the same time, since the guiding member 12121 is in contact with the guiding wall 1803, a frictional force will be generated therebetween, and this frictional force helps the bracket assembly 120 to remain stationary relative to the housing 180, thereby further reducing the possibility of the first outer support member 142 detaching from between the first bracket 121 and the second bracket 122 along the sliding direction.

[0246] To improve the smoothness of the sliding of the first outer support member 142 between the first bracket 121 and the second bracket 122, optionally, in an embodiment of the present invention, please refer to Fig.15 , Fig. 20 , Fig.40 and Fig.43 , one side of the first outer support member 142 facing the second bracket 122 includes a first guiding inclined surface 1421, and the first guiding inclined surface 1421 is provided on the inner support arm 1422. The second bracket 121 includes a second guiding inclined surface 127, and the first guiding inclined surface 1421 slides along the second guiding inclined surface 127 to achieve the mutual approach or separation of the first bracket 121 and the second bracket 122. In another embodiment, it may also be that one side of the first outer support member 142 facing the first bracket 121 includes a first guiding inclined surface 1421, and the first guiding inclined surface 1421 is provided on the inner support arm 1422. The first bracket 121 includes a second guiding inclined surface 127, and the first guiding inclined surface 1421 slides along the second guiding inclined surface 127. In other embodiments, it may also be that both sides of the first outer support member 142 facing the first bracket 121 and the second bracket 122 are provided with first guiding inclined surfaces 1421, and both the first bracket 121 and the second bracket 122 are provided with second guiding inclined surfaces 127, and the first guiding inclined surfaces 1421 on both sides of the first outer support member 142 slide with the corresponding second guiding inclined surfaces 127 on the corresponding sides respectively.

[0247] Through the cooperative design of the first guiding inclined surface 1421 and the second guiding inclined surface 127, not only can it play a guiding role in the sliding of the first outer support member 142 between the first bracket 121 and the second bracket 122, reducing the probability of deviation or misalignment during the sliding process, but also can improve the smoothness of the separation and approach processes of the first bracket 121 and the second bracket 122. Moreover, the mutual contact of the first guiding inclined surface 1421 and the second guiding inclined surface 127 can also form a relatively large contact area between the first outer support member 142 and the first bracket 121 and the second bracket 122 when the first bracket 121 and the second bracket 122 are in a separated state, which is beneficial to reducing the probability of the first outer support member 142 shifting out.

[0248] In addition, when the first outer support member 142 needs to slide out from between the first bracket 121 and the second bracket 122, the end cover 1424 is slid in the reverse direction to make the end cover 1424 slide from the second installation position to the first installation position. At this time, the pulling force of the pulling member 130 will make the first bracket 121 and the second bracket 122 approach each other. Since the first guide bevel 1421 and the second guide bevel 127 are matched with each other, the movement of the first bracket 121 and the second bracket 122 approaching each other will cause the first outer support member 142 to be automatically squeezed from the first position to the second position, thereby improving the convenience of sliding the first outer support member 142 out from between the first bracket 121 and the second bracket 122, and improving the user experience.

[0249] In order to further reduce the probability of the first outer support member 142 being skewed and displaced when sliding between the first bracket 121 and the second bracket 122 and ensure smooth sliding, optionally, in an embodiment of the present invention, refer to Fig.18 , Fig. 20 and Fig.44 The first guiding inclined surface 1421 is disposed on the side of the first outer support member 142 facing the second bracket 122, and the second guiding inclined surface 127 is disposed on the second bracket 122. Fig.18 As shown, the first bracket 121 is provided with a slide groove 125 at one end away from the seat body 141, and the slide groove 125 is arranged opposite to the first outer support member 142. The side of the first outer support member 142 away from the first guide inclined surface 1421 is at least partially accommodated in the slide groove 125. Along the height direction of the bracket assembly 120, the upper wall of the slide groove 125 abuts against the upper side surface of the first outer support member 142, the lower wall of the slide groove 125 abuts against the lower side surface of the first outer support member 142, and the bottom wall of the slide groove 125 abuts against the side wall of the first outer support member 142 away from the first guide inclined surface 1421.

[0250] In other embodiments, the first guiding slope 1421 may be disposed on the side of the first outer support member 142 facing the first bracket 121, and the second guiding slope 127 may be disposed on the first bracket 121. The second bracket 122 is provided with a slide groove 125 at one end away from the seat body 141, and the side of the first outer support member 142 away from the first guiding slope 1421 is at least partially accommodated in the slide groove 125.

[0251] By providing the sliding groove 125, when the first outer support member 142 slides between the first bracket 121 and the second bracket 122, the side of the first outer support member 142 facing away from the first guiding inclined surface 1421 can slide along the sliding groove 125. At the same time, the sliding groove 125 can also form a guiding limit for the first outer support member 142 in the height direction of the bracket assembly 120, further reducing the probability of skew displacement during the sliding of the first outer support member 140, thereby further ensuring the smoothness of the sliding of the first outer support member 142 between the first bracket 121 and the second bracket 122.

[0252] Furthermore, in order to prevent the first outer support member 142 from falling off between the first bracket 121 and the second bracket 122 during the sliding process, optionally, in an embodiment of the present invention, please refer to Fig. 9 、 Fig.36 、 Fig.44 and Fig.45 , a limiting rod 126 is provided on the first bracket 121, and the limiting rod 126 is arranged through the height direction of the sliding groove 125. The limiting rod 126 can be inserted into the first bracket 121 or fixedly connected to the first bracket 121 by threads. A limiting groove 1425 is provided on the first outer support member 142. The two ends in the length direction of the limiting groove 1425 are closed ends, and the length direction of the limiting groove 1425 is consistent with the sliding direction of the first outer support member 142. The limiting rod 126 is inserted into the limiting groove 1425 and can slide along the length direction of the limiting groove 1425. The dimension of the limiting groove 1425 along the width direction of the bracket assembly 120 is larger than the outer diameter of the limiting rod 126, so that the limiting rod 126 can slide along the width direction of the limiting groove 1425, thereby providing an avoidance space for the mutual approach and mutual separation between the first bracket 121 and the second bracket 122.

[0253] Through the cooperation of the limiting groove 1425 and the limiting rod 126, on the one hand, the limiting rod 126 slides along the limiting groove 1425, which can guide the sliding of the first outer support member 142 between the first bracket 121 and the second bracket 122. On the other hand, the limiting rod 126 cooperates with the limiting groove 1425, and can also prevent the first outer support member 142 from falling off after being disengaged from between the first bracket 121 and the second bracket 122, and further prevent the loss of the first outer support member 142.

[0254] In order to realize the insertion connection between the bracket assembly 120 and the seat body 141, optionally, in an embodiment of the present invention, please refer to Fig.15 and Fig.46, one end of the first bracket 121 close to the seat body 141 is connected with a first mounting portion 1217, and one end of the second bracket 122 close to the seat body 141 is connected with a second mounting portion 1222. The seat body 141 is provided with a first docking interface 1411 and a second docking interface 1412. The first docking interface 1411 is used for docking and connecting with the first docking portion 1217, and the second docking interface 1412 is used for docking and connecting with the second docking portion 1222. The outer support assembly 140 further includes a second outer support member 143. One end of the second outer support member 143 is connected with the seat body 141, and the other end of the second outer support member 143 is slidably inserted between the first mounting portion 1217 and the second mounting portion 1222. When the second outer support member 143 is inserted between the first mounting portion 1217 and the second mounting portion 1222, the first mounting portion 1217 and the second mounting portion 1222 are separated along the width direction of the bracket assembly 120, so that the first mounting portion 1217 is correspondingly inserted into the first docking interface 1411, and the second mounting portion 1222 is correspondingly inserted into the second docking interface 1412, thereby realizing the insertion connection between the first bracket 121 and the second bracket 122 and the seat body 141.

[0255] By providing the second outer support member 143 at one end of the seat body 141 and sliding the second outer support member 143 into the space between the first mounting portion 1217 and the second mounting portion 1222, the separation of the first bracket 121 and the second bracket 122 at one end close to the seat body 141 can be realized, and the first bracket 121 and the second bracket 122 can be maintained in a separated state to play an outer support role. Such a setting can facilitate the insertion connection between the first bracket 121 and the second bracket 122 and the seat body 141, and is beneficial to improving the connection efficiency between the bracket assembly 120 and the seat body 141.

[0256] To improve the sliding insertion accuracy of the second outer support member 143 relative to the bracket assembly 120, optionally, in an embodiment of the present invention, please refer to Fig.17 , Figure 46 and Figure 47 , a contact portion 1431 is provided at the end of the second outer support member 143 facing away from the seat body 141. The contact portion 1431 includes two groups. One group of the contact portions 1431 is provided on the side wall of the second outer support member 143 facing the first mounting portion 1217, and the other group of the contact portions 1431 is provided on the side wall of the second outer support member 143 facing the second mounting portion 1222.

[0257] Please refer to Figure 15 , Figure 17 , Figure 23 , Figure 47 and Figure 48, a third guiding inclined surface 1204 is respectively arranged on each of the first mounting part 1217 and the second mounting part 1222 on two oppositely arranged side walls. The abutting part 1431 on each side corresponds to a third guiding inclined surface 1204 on the same side. During the process of the second outer support member 143 being slidably inserted into the first mounting part 1217 and the second mounting part 1222, the abutting part 1431 slides along the third guiding inclined surface 1204 to realize the mutual separation or mutual approach of the first mounting part 1217 and the second mounting part 1222, and further realize the mutual approach or mutual separation of the first bracket 121 and the second bracket 122 at one end close to the seat body 141.

[0258] The abutting part 1431 can be an inclined surface structure or a combined structure of a plane and an inclined surface. Optionally, please refer to Figure 17 and Figure 48 , in this embodiment, the abutting part 1431 includes an inclined surface section 1434 and a plane section 1433 which are connected to each other. The plane section 1433 is connected to one end of the inclined surface section 1434 far from the seat body 141. A plane guiding section 1205 is respectively arranged on each of the first bracket 121 and the second bracket 122 on two oppositely arranged side walls. As Figure 49 shown, when the first bracket 121 and the second bracket 122 approach each other, the plane guiding sections 1205 on both sides are mutually attached to limit the attachment distance between the first bracket 121 and the second bracket 122. As Figure 50 shown, when the first bracket 121 and the second bracket 122 are separated from each other, that is, when the second outer support member 143 is slidably inserted between the first mounting part 1217 and the second mounting part 1222, the plane guiding sections 1205 on both sides are gradually separated to form an insertion area 1206 for the abutting part 1431 to be inserted, and the plane sections 1433 on both sides respectively abut against the plane guiding sections 1205 on both sides.

[0259] Please refer to Figure 48 and Figure 50 , when the second outer support member 143 is inserted between the first mounting part 1217 and the second mounting part 1222, the plane sections 1433 on both sides of the abutting part 1431 first slide along the corresponding third guiding inclined surface 1204, and drive the inclined surface sections 1434 on both sides to gradually slide into the space between the two third guiding inclined surfaces 1204. As the first bracket 121 and the second bracket 122 are separated, the plane guiding sections 1205 on both sides are gradually separated to form an insertion area 1206. The abutting part 1431 continues to slide, the front-end plane section 1433 gradually enters the insertion area 1206 and abuts against the plane guiding section 1205 on the corresponding side, and the rear-end inclined surface section 1434 is gradually completely attached to the third guiding inclined surface 1204. At this time, it indicates that the second outer support member 143 is inserted in place and the insertion action stops.

[0260] Through the cooperation of the third guiding inclined surface 1204 and the planar guiding section 1205, the planar section 1433 and the inclined surface section 1434 of the abutting portion 1431 can gradually slide in and be accurately positioned. With such an arrangement, on the one hand, the probability of deviation from the preset direction during the sliding of the second outer support member 143 between the first support 121 and the second support 122 can be reduced, thereby improving the position accuracy of the insertion of the second outer support member 143 and ensuring the consistency of multiple insertions. On the other hand, after the second outer support member 143 is inserted, due to the mutual contact between the planar section 1433 and the planar guiding section 1205, and the mutual fitting between the inclined surface section 1434 and the third guiding inclined surface 1204, therefore, the external load generated between the second outer support member 143 and the support assembly 120 can be effectively dispersed. This load dispersion mechanism can enhance the overall stability and load-bearing capacity of the connection structure between the support assembly 120 and the seat body 141, and at the same time is also beneficial to reducing local stress concentration and extending the service life of the structure.

[0261] Under the condition that the outer support assembly 140 includes the first outer support member 142 and the second outer support member 143, there can be various disassembly and assembly methods between the support assembly 120 and the outer support assembly 140. In an embodiment, when the support assembly 120 needs to be installed on the outer support assembly 140, the first outer support member 142 can be first inserted into one end of the first support 121 and the second support 122 outside the housing 180, and then the support assembly 120 is moved to the inside of the receiving cavity 190 to insert the second outer support member 143 between the first support 121 and the second support 122. Thus, the connection between the support assembly 120 and the outer support assembly 143 is completed, and at the same time, the tensioning of the cleaning member 110 is also realized. Correspondingly, when the support assembly 120 needs to be removed from the outer support assembly 140, at this time, the first outer support member 142 can be first slid out from between the first support 121 and the second support 122, and then the support assembly 120 is moved to the outside of the receiving cavity 190 to slide the second outer support member 143 out from between the first support 121 and the second support 122. Thus, the removal between the support assembly 120 and the outer support assembly 140 is completed, and at the same time, the relaxation of the cleaning member 110 is also realized.

[0262] In another embodiment, when the bracket assembly 120 needs to be installed on the outer support assembly 140, the bracket assembly 120 can also be moved to the receiving cavity 190 together with the cleaning member 110 and the first support member 142 first, so that the second outer support member 143 is first inserted between the first bracket 121 and the second bracket 122, and then the first outer support member 142 is slidably inserted between the first bracket 121 and the second bracket 122. In this way, the connection between the bracket assembly 120 and the outer support assembly 140 can be realized, and at the same time, the tension of the cleaning member 110 is also realized. Correspondingly, when the bracket assembly 120 needs to be removed from the outer support assembly 140, at this time, the bracket assembly 120 can be moved to the outside of the receiving cavity 190 first, so that the second outer support member 143 slides out from between the first bracket 121 and the second bracket 122, and then the first outer support member 142 slides out from between the first bracket 121 and the second bracket 122. In this way, the removal between the bracket assembly 120 and the outer support assembly 140 can be realized, and at the same time, the relaxation of the cleaning member 110 is also realized. In the actual use process, the user can select according to his own operation habits.

[0263] In order to further improve the insertion and positioning accuracy between the second outer support member 143 and the first bracket 121 and the second bracket 122, optionally, in an embodiment of the present invention, please refer to Figure 27 , Figure 28 , Figure 47 and Figure 48 , the second outer support member 143 further includes two sets of insertion slots 1432. One set of insertion slots 1432 is arranged on the side facing the first mounting portion 1217, and the other set of insertion slots 1432 is arranged on the side facing the second mounting portion 1222. The first mounting portion 1217 and the second mounting portion 1222 are both provided with clamping blocks 128 matching the insertion slots 1432 on the opposite side walls. The clamping blocks 128 are correspondingly inserted into the insertion slots 1432 and can slide along the insertion slots 1432. Along the height direction of the bracket assembly 120, the upper wall of the insertion slot 1432 abuts against the upper side wall of the clamping block 128, and the lower wall of the insertion slot 1432 abuts against the lower side wall of the clamping block 128. By providing the insertion slots 1432 and the clamping blocks 128, the insertion slots 1432 and the clamping blocks 128 cooperate to realize the positioning in the height direction of the bracket assembly 120 when the second outer support member 143 is inserted between the first bracket 121 and the second bracket 122. Therefore, the insertion and positioning accuracy between the second outer support member 143 and the first bracket 121 and the second bracket 122 can be further improved, and the insertion efficiency of the first bracket 121 and the second bracket 122 with the seat body 141 can be correspondingly improved.

[0264] In order to improve the cleaning efficiency of the cleaning member 110 and reduce the number of times of replacing the cleaning member 110, optionally, in an embodiment of the present invention, please refer to Figure 4 andFigure 31 The bracket assembly 120 further includes a roller structure rotatably provided on the bracket body. The roller structure includes a roller body. At least two sets of roller structures are provided on the bracket body. The roller body of one set of roller structures is the first roller 1201, and the roller body of the other set of roller structures is the second roller 1202. Both the first roller 1201 and the second roller 1202 are rotatably connected to the bracket body. Specifically, the first roller 1201 is rotatably installed on the outer side of the first bracket 121, that is, on the side of the first bracket 121 facing away from the second bracket 122. The second roller 1202 is rotatably installed on the outer side of the second bracket 122, that is, on the side of the second bracket 122 facing away from the first bracket 121, and the second roller 1202 is arranged parallel to the first roller 1201.

[0265] The cleaning member 110 is wound around and covered on the outer peripheral surfaces of the first roller 1201 and the second roller 1202. When the first roller 1201 and the second roller 1202 rotate, the cleaning member 110 can be driven to rotate. It should be noted that the first roller 1201 and the second roller 1202 can be non-powered rollers, that is, they rotate by the frictional force between the cleaning member 110 and the surface to be cleaned. One of the first roller 1201 and the second roller 1202 can also be a powered roller, and the other is a non-powered driven roller. For example, a driving assembly is provided at one end of the first roller 1201 or the second roller 1202. When the driving assembly rotates, it drives the first roller 1201 or the second roller 1202 to rotate, and then drives the cleaning assembly 100 to rotate.

[0266] By providing the first roller 1201 and the second roller 1202, the rotational operation of the cleaning member 110 can be realized, and thus the entire outer peripheral surface of the cleaning member 110 can be brought into contact with the surface to be cleaned for cleaning operations. This can increase the working area of the cleaning member 110, thereby reducing the replacement frequency of the cleaning member 110 and improving the cleaning efficiency of the cleaning member 110.

[0267] The roller body further includes a first end seat and a second end seat. The first end seat and / or the second end seat is detachably connected to the bracket body. The roller body is rotatably connected between the first end seat and the second end seat, and moreover, the roller body is detachably installed between the first end seat and the second end seat. After such a setting, the first end seat and / or the second end seat can be detached from the bracket body to realize the detachment of the roller body. When the roller body is deformed or damaged, the roller body can be replaced. At the same time, it is also convenient for the user to detach the roller body, the first end seat, and the second end seat from the bracket assembly simultaneously, which is convenient for later cleaning and maintenance.

[0268] In one embodiment, the first end seat is detachably connected to the bracket body, and the second end seat is fixedly connected to the bracket body; in another embodiment, the first end seat is fixedly connected to the bracket body, and the second end seat is detachably connected to the bracket body. After such a setting, one of the first end seat and the second end seat can be detached from the bracket body, while the other cannot be detached from the bracket body, which simplifies the alignment difficulty of disassembling and assembling the roller body and installing the first end seat or the second end seat. At the same time, the non-detachable components can also reduce the possibility of component loss, thereby improving the user experience.

[0269] First, the following embodiments will introduce in detail the connection structure between the first roller 1201 and the bracket assembly 120, and between the first roller 1201 and the seat body 141 when the roller body is the first roller 1201.

[0270] Please refer to Figure 52 and Figure 53 , the bracket assembly 120 further includes a first support seat 12011 and a second support seat 12012. When the roller body is the first roller 1201, the first end seat is the first support seat 12011, and the second end seat is the second support seat 12012. The first support seat 12011 and the second support seat 12012 are respectively fixedly connected to both ends of the first bracket 121 in the length direction. Among them, the first support seat 12011 is fixedly connected to one end of the first bracket 121 close to the housing connection part 1212, and the fixed connection method can be integrally injection-molded connection or fixed connection through fasteners such as bolts. Optionally, in this embodiment, please refer to Figure 52 and Figure 60 , the first support seat 12011 is integrally formed with the first bracket 121. The second support seat 12012 is detachably connected to one end of the first bracket 121 close to the seat body 141, and the detachable connection method can be bolt detachable connection, snap detachable connection, etc. Please refer to Figure 60 , Figure 62 and Figure 63 , the first support seat 12011 is provided with a first insertion hole 12017, and the second support seat 12012 is provided with a second insertion hole 12018. It should be noted that in this embodiment, the second support seat 12012 is the same component as the first installation part 1217 in the foregoing embodiment.

[0271] Please refer to Figures 53 to 55, one end of the first roller 1201 is provided with a first shaft end 12014, and the other end is provided with a second shaft end 12015. Both the first shaft end 12014 and the second shaft end 12015 are rotatably connected to the bracket body. The first shaft end 12014 is arranged close to the housing connection part 1212, and the second shaft end 12015 is arranged close to the base 141. The cleaning assembly 100 further includes a driving structure 160, and the driving structure 160 is connected to the base 141. The second shaft end 12015 is drivingly connected to the driving structure 160, and the shaft diameter of the second shaft end 12015 is larger than that of the first shaft end 12014. After such a setting, the second shaft end 12015 can bear a greater torque, so that the power of the driving structure 160 can be transmitted to the first roller 1201 more stably. In addition, since the shaft diameter of the second shaft end 12015 is larger than that of the first shaft end 12014, during the process of installing the bracket assembly 120 with the cleaning part 110 into the receiving cavity 190, the first shaft end 12014 and the second shaft end 12015 with different shaft diameters have an anti-misoperation effect, which can prevent the user from installing the bracket assembly 120 with the cleaning part 110 in the receiving cavity 190 in the reverse direction, thereby increasing the probability of the user accurately installing the bracket assembly 120.

[0272] Please refer to Figures 53 to 55 , a first bearing 12005 is rotatably connected to the first shaft end 12014, and the first shaft end 12014 is rotatably connected to the bracket body through the first bearing 12005. A first clamping part 12016 is provided on the first shaft end 12014. The first clamping part 12016 is sleeved outside the first bearing 12005, and the first clamping part is rotatably connected to the first shaft end 12014 through the first bearing 12005. A rotating sleeve 12019 is rotatably connected to the second shaft end 12015, and the second shaft end 12015 is rotatably connected to the bracket body through the rotating sleeve 12019. The wall thickness of the rotating sleeve 12019 is smaller than the wall thickness of the first bearing 12005, and the inner diameter of the rotating sleeve 12019 is larger than the inner diameter of the first bearing. The first clamping part 12016 is inserted into the first insertion hole 12017, and the rotating sleeve 12019 is inserted into the second insertion hole 12018. Please refer to Figure 56 , the rotating sleeve 12019 and the second shaft end 12015 are in a shaft-hole fit and rotatably connected, and the rotating sleeve 12019 is made of a self-lubricating material. The self-lubricating material can be a polyoxymethylene-based material, a polyamide-based material, a metal-plastic composite self-lubricating material, etc. Specifically, the outer circle of the rotating sleeve 12019 is in a tight fit with the second insertion hole 12018 to realize the fixed connection of the rotating sleeve 12019 relative to the second insertion hole 12018, and the inner circle of the rotating sleeve 12019 is in a clearance fit with the second shaft end 12015 to realize the rotating connection between the second shaft end 12015 and the rotating sleeve 12019.

[0273] In the prior art, the rotational connection between the second shaft end 12015 and the second insertion hole 12018 is usually achieved through a bearing. However, since the shaft diameter of the first shaft end 12014 needs to be larger than that of the second shaft end 12015, and the inner space of the second insertion hole 12018 is limited, the current bearing manufacturing process cannot manufacture a bearing with an outer diameter adapted to the second insertion hole 12018 and an inner diameter adapted to the second shaft end 12015. This is because a bearing generally includes an outer ring, an inner ring, and rolling elements. The rolling elements are arranged between the outer ring and the inner ring. Limited by the rolling elements, the minimum value of the wall thickness of the bearing is limited. In this embodiment, a rotating sleeve 12019 is adopted to achieve the rotational connection between the second shaft end 12015 and the second insertion hole 12018. The structure of the rotating sleeve 12019 is simpler than that of a bearing. The current manufacturing process can completely manufacture a rotating sleeve 12019 with an outer diameter adapted to the second insertion hole 12018 and an inner diameter adapted to the second shaft end, providing the feasibility for the shaft diameter of the second shaft end 12015 to be larger than that of the first shaft end 12014, and for both the first shaft end 12014 and the second shaft end 12015 to be rotationally connected to the bracket body.

[0274] Please refer to Figure 55 , the first roller 1201 includes a first inner core 120005, the first inner core 120005 is made of metal, and the first inner core 120005 is integrally formed between the first shaft end 12014 and the second shaft end 12015. The second roller 1202 includes a second inner core 120006, and the second inner core 120006 is made of metal. The shaft diameter of the first inner core 120005 is larger than that of the second inner core 120006. After such a setting, the first inner core 120005 can withstand a greater torque, enabling the power of the driving structure 160 to be transmitted to the first roller 1201 more stably.

[0275] To further improve the insertion efficiency of the first engaging member 12016 and the first support seat 12011, optionally, in an embodiment, please refer to Figure 55, the first clamping member 12016 includes a cylindrical section 12071 and a frustum section 12072 that are connected to each other, and the frustum section 12072 is disposed at one end of the cylindrical section 12071 facing the first insertion hole 12017. The first insertion hole 12017 includes a cylindrical hole 12081 and a frustum hole 12082 that are connected to each other. The cylindrical hole 12081 matches the cylindrical section 12071, and the frustum hole 12082 matches the frustum section 12072. With such a setting, on the one hand, the frustum section 12072 can play a centering and positioning role in the initial stage when the first clamping member 12016 is inserted into the first insertion hole 12017, facilitating the smooth insertion of the first clamping member 12016 into the first insertion hole 12017 and improving the insertion efficiency. On the other hand, when the first clamping member 12016 is inserted into the first insertion hole 12017, not only can a conical surface fit be formed between the frustum section 12072 and the frustum hole 12082, but also a cylindrical surface fit can be formed between the cylindrical section 12071 and the cylindrical hole 12081. Therefore, a double-fit positioning structure can be formed, which is beneficial to improving the stability of the insertion between the two. It should be noted that in order to facilitate the axial positioning between the first clamping member 12016 and the first support seat 12011, the first insertion hole 12017 provided on the first support seat 12011 is a blind hole structure.

[0276] Optionally, in one embodiment, please refer to Figure 55, the first insertion hole 12017 includes a first bottom wall 12091, and the first bottom wall 12091 is provided with a positioning protrusion 12092. A first positioning hole 12093 is defined among the positioning protrusion 12092, the side wall of the frustum-shaped hole 12082, and the first bottom wall 12091. The first clamping member 12016 is provided with a stepped stage 120161 and a through-hole section 120162, and the through-hole section 120162 is located at one end close to the first bottom wall 12091. The stepped stage 120161 is used for mounting the first bearing 12005. The first shaft end 12014 passes through the first bearing 12005 and at least partially extends into the through-hole section 120162, and the extending length does not exceed the frustum section 12072 of the first clamping member 12016. At least a part of the frustum section 12072 of the first clamping member 12016 is received in the first positioning hole 12093, and the end face of the frustum section 12072 abuts against the first bottom wall 12091 in the axial direction. The positioning protrusion 12092 is in plug-in fit with the through-hole section 120162, and the positioning protrusion 12092 is correspondingly inserted into the through-hole section 120162, and an axial gap is formed between the positioning protrusion 12092 and the first shaft end 12014. With such a setting, the frustum section 12072 of the first clamping member 12016 can be inserted into the first positioning hole 12093, and the positioning protrusion 12092 is correspondingly inserted into the through-hole section 120162. This structural design makes the plug-in positioning between the first clamping member 12016 and the first insertion hole 12017 more accurate, ensuring the centering accuracy during the assembly of the two. At the same time, due to the mutual cooperation between the frustum section 12072 and the first positioning hole 12093, and between the positioning protrusion 12092 and the through-hole section 120162, the first clamping member 12016 is easier to align when inserted into the first insertion hole 12017, reducing the adjustment time and operation difficulty during the assembly process and improving the assembly efficiency.

[0277] To achieve the connection between the first roller 1201 and the seat body 141, optionally, in an embodiment of the present invention, please refer to Figure 54 , Figure 63 , Figure 64 and Figure 67 , the second insertion hole 12018 provided on the second support seat 12012 is a through-hole structure. The second shaft end 12015 passes through the rotating sleeve 12019 and extends to the outside of the second insertion hole 12018. The part of the second shaft end passing through the second support seat forms a driving section, and the driving section is drivingly connected to the driving structure. The seat body 141 includes a first connecting shaft 12001, and the first mating interface 1411 includes a first mounting hole 14111. The first connecting shaft 12001 is inserted into the first mounting hole 14111. The first connecting shaft 12001 can be rotatably connected to the first mounting hole 14111 or fixedly connected to the first mounting hole 14111. Optionally, in this embodiment, please refer to Figure 54 and Figure 64, a second bearing 12003 is arranged in the first mounting hole 14111, and the first connecting shaft 12001 is rotationally connected to the first mounting hole 14111 through the second bearing 12003, so as to realize the rotational connection of the first connecting shaft 12001 relative to the seat body 141. A plugging blind hole 12002 is arranged on one side of the first connecting shaft 12001 facing the second support seat 12012, and the second shaft end 12015 is plugged into the plugging blind hole 12002. Specifically, the driving section of the second shaft end 12015 is plugged into the plugging blind hole 12002.

[0278] With such a setting, on the one hand, the insertion connection between the first roller 1201 and the seat body 141 can be realized, making the connection process simpler, and the axial positioning and connection can be quickly realized. At the same time, the alignment difficulty in the assembly process is also reduced, and the assembly efficiency is improved. On the second hand, by designing the second insertion hole 12018 as a through-hole structure, the second shaft end 12015 can penetrate through the rotating sleeve 12019 and extend to the outside. This design provides greater flexibility for the connection between the first roller 1201 and the seat body 141. At the same time, the connection method (rotational or fixed connection) between the first connecting shaft 12001 and the seat body 141 can be selected according to actual needs, further enhancing the adaptability and stability of the structure.

[0279] Secondly, in the following embodiments, when the roller body is the second roller 1202, the connection between the second roller 1202 and the bracket assembly 120 will be introduced in detail.

[0280] Optionally, in an embodiment, please refer to Figure 52 and Figure 56 , the bracket assembly 120 further includes a third support seat 12023 and a fourth support seat 12024. When the roller body is the second roller 1202, the first end seat is the third support seat 12023, and the second end seat is the fourth support seat 12024. The third support seat 12023 and the fourth support seat 12024 are respectively fixedly connected to both ends of the second bracket 122 in the length direction. Among them, the third support seat 12023 is fixedly connected to one end of the second bracket 122 close to the housing connection part 1212. The fixed connection method can be integrally injection-molded connection or fixed connection through fasteners such as bolts. Optionally, in this embodiment, please refer to Figure 52 and Figure 60 , the third support seat 12023 is integrally formed with the second bracket 122. The third support seat 12023 is slidably connected to the housing connection part 1212, and the sliding direction is the same as the direction in which the first bracket 121 and the second bracket 122 move relative to each other. The fourth support seat 12024 is detachably connected to one end of the second bracket 122 close to the seat body 141. The detachable connection method can be bolt detachable connection, snap detachable connection, etc. Please refer to Figure 60 and Figure 61, the third support base 12023 is provided with a third insertion hole 12028, and the fourth support base 12024 is provided with a fourth insertion hole 12029. It should be noted that in this embodiment, the fourth support base 12024 is the same component as the second connecting portion 1222 in the foregoing embodiment.

[0281] It should be noted that there are various ways for the third support base 12023 to be slidably connected to the housing connecting portion 1212. Optionally, in this embodiment, please refer to Figure 59 and Figure 60 , the housing connecting portion 1212 is provided with a bracket chute 1214, and the bracket chute 1214 extends along the direction in which the first bracket 121 and the second bracket 122 move relative to each other. The third support base 12023 is snap-connected to the bracket chute 1214 and can slide along the bracket chute 1214, and the sliding direction is as shown by the W5 direction in Figure 60 .

[0282] Please refer to Figures 56 to 58 , one end of the second roller 1202 is provided with a third shaft end 12025, and the other end is provided with a fourth shaft end 12026. The shaft diameters of the third shaft end 12025 and the fourth shaft end 12026 are smaller than the shaft diameter of the second shaft end 12015. The third shaft end 12025 is arranged on the side close to the housing connecting portion 1212, and the fourth shaft end 12026 is arranged on the side close to the seat body 141. A third clamping member 12027 is rotatably connected to the third shaft end 12025, and a fourth clamping member 12022 is rotatably connected to the fourth shaft end 12026. The third clamping member 12027 is inserted into the third insertion hole 12028, and the fourth clamping member 12022 is inserted into the fourth insertion hole 12029. The connection between the third clamping member 12027 and the third shaft end 12025, and the connection between the fourth clamping member 12022 and the fourth shaft end 12026 can be realized by rotation through a bearing, or can be realized by rotation through shaft-hole cooperation. Optionally, in this embodiment, the third clamping member 12027 is rotatably connected to the third shaft end 12025 through a third bearing 12004, and the fourth clamping member 12022 is rotatably connected to the fourth shaft end 12026 through a fourth bearing 12006. Both the third insertion hole 12028 and the fourth insertion hole 12029 are blind hole structures.

[0283] In one embodiment, the insertion structure between the third clamping member 12027 and the third insertion hole 12028, and the insertion structure between the fourth clamping member 12022 and the fourth insertion hole 12029 can both adopt the insertion method of the first clamping member 12016 and the first insertion hole 12017 in the above embodiment.

[0284] Of course, in other embodiments, the insertion structure between the third engaging member 12027 and the third insertion hole 12028, and the insertion structure between the fourth engaging member 12022 and the fourth insertion hole 12029 may also adopt a connection method different from the insertion method of the first engaging member 12016 and the first insertion hole 12017 in the above embodiments, as long as the insertion requirements can be met.

[0285] To achieve the connection between the second roller 1202 and the seat body 141, optionally, in an embodiment of the present invention, please refer to Figure 57 、 Figure 61 and Figure 67 , the second mating interface 1412 further includes a second mounting hole 14121, and one side of the fourth support seat 12024 facing the seat body 141 further includes a docking end 120241 adapted to the second mounting hole 14121. The docking end 120241 is provided at one end of the second roller 1202 facing the seat body 141, and the docking end 120241 is inserted into the second mounting hole 14121. By inserting the docking end 120241 of the fourth support seat 12024 into the second mounting hole 14121 along the axial direction of the second roller 1202, the insertion between the fourth support seat 12024 and the seat body 141 can be achieved. This connection method has a simple structure and a relatively high insertion positioning accuracy, and is more suitable for the repeated connection working conditions between the second roller 1202 and the seat body 141.

[0286] Since the first roller 1201 and the second roller 1202 will be subjected to a relatively large tensile force when the cleaning member 110 is in a tensioned state, which affects the stability of their support. Therefore, in order to improve the stability of the support of the first roller 1201 and the second roller 1202 for the cleaning member 110, optionally, in an embodiment of the present invention, please refer to Figure 52 and Figure 68 , the first roller 1201 and the second roller 1202 are further provided with abutting sections 1203 at positions near the middle of their own lengths. The abutting section 1203 is a shaft section with a smaller diameter provided on the first roller 1201 or the second roller 1202. When the cleaning member 110 is wound around the first roller 1201 and the second roller 1202, the abutting section 1203 may or may not contact the cleaning member 110. Optionally, in this embodiment, please refer to Figure 68, a convex ring structure 111 corresponding to the abutting section 1203 is arranged on the inner wall of the cleaning part 110. The convex ring structure 111 can be clamped with the abutting section 1203, so as to play an installation positioning role in the installation of the cleaning part 110 in the length direction of the bracket assembly 120. The first bracket 121 and the second bracket 122 are correspondingly provided with supporting parts 129. The supporting part 129 on the first bracket 121 extends towards the abutting section 1203 on the first roller 1201 and is in rotational abutment with the corresponding abutting section 1203. The supporting part 129 on the second bracket 122 extends towards the abutting section 1203 on the second roller 1202 and is in rotational abutment with the corresponding abutting section 1203.

[0287] In other embodiments, it may also be that an abutting section 1203 is arranged on one of the first roller 1201 and the second roller 1202, and a supporting part 129 is arranged on the first bracket 121 or the second bracket 122 corresponding to the abutting section 1203. This can also improve the supporting stability of the first roller 1201 and the second roller 1202 on the cleaning part 110.

[0288] By arranging the abutting section 1203 and the supporting part 129 so that the abutting section 1203 and the supporting part 129 are in rotational abutment, an abutting force opposite to the tension force of the cleaning part 110 can be additionally formed between the two ends of the first roller 1201 and the second roller 1202, so as to offset part of the tension force generated by the cleaning part 110 on the first roller 1201 and the second roller 1202, reduce the probability of the first roller 1201 and the second roller 1202 being bent and deformed due to force, and thus improve the supporting stability of the first roller 1201 and the second roller 1202 on the cleaning part 110.

[0289] In order to form a better frictional force between the cleaning part 110 and the first roller 1201 or the second roller 1202 and reduce the probability of slipping during the rotation of the cleaning part 110, optionally, please refer to Figure 53 and Figure 56, in an embodiment of the present invention, at least a part of the outer peripheral surfaces of the first roller 1201 and the second roller 1202 is made of rubber material. Here, at least a part being made of rubber material means that at least a part of the outer peripheral surfaces of the first roller 1201 and the second roller 1202 in contact with the cleaning member 110 is made of rubber material. In one embodiment, it may be that the outer peripheral surfaces of the first roller 1201 and the second roller 1202 in contact with the cleaning member 110 are both made of rubber material. It may also be that the outer peripheral surface of one of the first roller 1201 and the second roller 1202 in contact with the cleaning member 110 is made of rubber material. It may further be that a part of the outer peripheral surfaces of the first roller 1201 and the second roller 1202 in contact with the cleaning member 110 is made of rubber material. The rubber material may be a rubber ring structure coated on the outer peripheral surface of the first roller 1201 or the second roller 1202, or may be a structure such as a plurality of dot-shaped rubber protrusions or strip-shaped rubber protrusions distributed on the first roller 1201 or the second roller 1202. During the actual design and production process, it needs to be determined according to the actual rotational frictional force between the cleaning member 110 and the first roller 1201 and the second roller 1202. The rubber material may be a hard rubber material or a soft rubber material, as long as it meets the transmission requirements between the first roller 1201 and the second roller 1202 and the cleaning member 110.

[0290] By providing a rubber material on the outer peripheral surfaces of the first roller 1201 and the second roller 1202, the transmission frictional force between the cleaning member 110 and the first roller 1201 and the second roller 1202 can be increased, the friction condition can be improved, and further the probability of the cleaning member 110 slipping during rotation can be reduced, thereby improving the cleaning effect of the cleaning member 110. At the same time, since the rubber material also has certain shock absorption and noise reduction properties, the noise generated during the operation of the cleaning assembly 100 can also be reduced, enhancing the user experience.

[0291] Optionally, in an embodiment of the present invention, please refer to Figure 6 and Figure 31 , the cleaning assembly 100 further includes a driving structure 160. The driving structure 160 is disposed on the seat body 141 and drives the first roller 1201 to rotate. Specifically, the driving structure 160 is drivingly connected to the second shaft end 12015. The driving structure 160 may be a direct drive structure of a motor, a combined structure of a motor and a gear assembly, a combined structure of a motor and a transmission belt, etc., as long as it can realize the rotation of the first roller 1201, and this embodiment does not limit this. The fixed end of the driving structure 160 is disposed on the seat body 141, the output end of the driving structure 160 is connected to the first roller 1201, and the output end of the driving structure 160 rotates to drive the first roller 1201 to rotate.

[0292] By setting the driving structure 160, the rotation of the driving structure 160 can drive the rotation of the first roller 1201, and the rotation of the first roller 1201 drives the cleaning member 110 and the second roller 1202 to rotate. Since the driving structure 160 can provide a stable power output, the cleaning member 110 can obtain a stable rotational speed, thereby ensuring the stability of the cleaning efficiency and cleaning effect. At the same time, it is not restricted by the frictional force of the surface to be cleaned and can be applied to more cleaning scenarios.

[0293] Optionally, in an embodiment of the present invention, please refer to Figure 31 and Figure 69 , one end of the first connecting shaft 12001 is drivingly connected to the driving structure 160, the driving structure 160 is used to drive the rotation of the first connecting shaft 12001, and the other end of the first connecting shaft 12001 extends out of the seat body 141 and is connected to the second shaft end 12015. The driving structure 160 includes a first driving member 161 and a gear assembly 162. The first driving member 161 can be any mechanism capable of realizing rotational motion such as a motor, a hydraulic pump, etc. Optionally, in this embodiment, the first driving member 161 is a motor. The input end of the gear assembly 162 is connected to the output end of the first driving member 161, and the gear assembly 162 includes a first output end 1621, and the first output end 1621 is connected to the first roller 1201 to drive the first roller 1201 to rotate. The gear assembly 162 can include multiple sets of gear transmission structures or only one set of gear transmission structures, specifically subject to meeting the transmission connection requirements between the motor and the first roller 1201.

[0294] Since the gear assembly 162 can achieve a compact layout through reasonable design, the installation space on the seat body 141 can be saved, making the overall structure of the cleaning assembly 100 lighter and more compact. At the same time, the gear assembly 162 also has a high transmission efficiency, which is beneficial to improving the rotation efficiency of the cleaning member 110 and reducing energy loss.

[0295] Specifically, in this embodiment, please refer to Figure 69, the gear assembly 162 includes a first gear structure 1623 and a second gear structure 1624. The first driving member 161 drives the first gear structure 1623 to rotate. A double-layer gear structure is provided on the output shaft of the first gear structure 1623. For the convenience of description, they are respectively marked as the first gear 16231 and the second gear 16232. Among them, the first gear 16231 is in transmission connection with the second gear structure 1624 to drive the first roller 1201 to rotate, and further drive the cleaning member 110 to rotate. The output end of the second gear structure 1624 forms the first output end 1621 of the gear assembly 162. The first output end 1621 is provided with a first output gear 16211. The first output gear 16211 is installed on the first connecting shaft 12001. When the first output gear 16211 rotates, it drives the first connecting shaft 12001 to rotate, and further drives the first roller 1201 to rotate. On one side of the seat body 141 facing away from the second outer support member 143, there is a receiving cavity 1413, and the gear assembly 162 is arranged in the receiving cavity 1413. The seat body 141 further includes a gearbox cover 14131. The gearbox cover 14131 is arranged at the opening position of the receiving cavity 1413, and the gearbox cover 14131 is detachably connected to the seat body 141. Among them, both the first gear structure 1623 and the second gear structure 1624 are gear train structures, which will not be elaborated here.

[0296] In one embodiment, please refer to Figure 5 , Figure 54 , Figure 69 , on the side of the gearbox cover 14131 facing the first output gear 16211, there is also a third mounting hole 14132. A fifth bearing 12007 is installed in the third mounting hole 14132. One end of the first connecting shaft 12001 extending out of the first output gear 16211 is connected to the fifth bearing 12007 to realize the rotational support of the first connecting shaft 12001 on the gearbox cover 14131. With this setting, the second bearing 12003 and the fifth bearing 12007 are respectively arranged at both ends of the first output gear 16211, so that the support stability of the first connecting shaft 12001 for the first output gear 16211 can be improved, and at the same time, the stability of the first connecting shaft 12001 during rotation can be improved.

[0297] By providing the gearbox cover 14131, the gearbox cover 14131 can effectively block external dust, impurities, moisture, etc. from entering the receiving cavity 1413, avoiding these foreign matters from mixing into the gear assembly 162, thereby reducing the wear of the gear assembly and the decline of the meshing accuracy, and further reducing the maintenance and replacement costs of the equipment.

[0298] In order to improve the transmission accuracy between the first roller 1201 and the first connecting shaft 12001 and reduce the probability of slipping between the first roller 1201 and the first connecting shaft 12001. Optionally, in one embodiment, please refer to Figure 71, the insertion blind hole 12002 on the first connecting shaft 12001 is a polygonal hole structure, such as a quadrilateral hole, a hexagonal hole, an octagonal hole, etc. The second shaft end 12015 of the first roller 1201 is a multi-edge structure corresponding to the polygonal hole 1415. With this setting, since the cooperation between the polygonal hole and the multi-edge structure can provide a larger contact area and a tighter mechanical connection, compared with the traditional cylindrical hole structure, this design can significantly increase the tightness of the fit between the second shaft end and the insertion blind hole, thereby improving the transmission accuracy between the second shaft end and the first connecting shaft. At the same time, since the cooperation mode between the polygonal hole and the multi-edge structure can increase the friction between the two, it can effectively reduce the slipping phenomenon caused by changes in axial or radial loads. Therefore, this connection structure is more suitable for high-torque or high-precision transmission scenarios.

[0299] Of course, in some other embodiments, the insertion blind hole 12002 can also be a common cylindrical hole, and the second shaft end 12015 is a cylindrical structure, and the cylindrical structure is inserted into the cylindrical hole. By controlling the tightness of the fit between the insertion blind hole 12002 and the second shaft end 12015, the transmission accuracy between the first connecting shaft 12001 and the second shaft end 12015 can also be achieved.

[0300] Under the condition that the second shaft end 12015 and the first connecting shaft 12001 adopt the insertion method of matching the polygonal hole and the multi-edge structure, in order to further improve the stability of power transmission between the first roller 1201 and the driving structure 160, optionally, in an embodiment, please refer to Figures 77 to 79 , along the axial direction of the first roller 1201, the length of the second shaft end 12015 is greater than the length of the docking end 120241. Further, the length of the driving section of the second shaft end 12015 is greater than the length of the docking end 120421. Define the length of the driving section as A and the length of the docking end 120421 as B. The relationship between the length ratios of A and B is 0 < B / A < 1. Preferably, B / A can be 1 / 2, 1 / 3, 1 / 4, etc. After such a setting, during the process of inserting the docking end 120241 into the second mounting hole 14121 and the driving section into the insertion blind hole 12002, since the length of the driving section of the second shaft end 12015 is greater than the length of the docking end 120241, therefore, the driving section first enters the insertion blind hole 12002 to achieve preliminary alignment. When the driving section is about to completely enter the insertion blind hole 12002, through the alignment of the driving section, the docking end 120241 can quickly enter the second mounting hole 14121 without the user having to find the position accurately multiple times. Utilizing the preliminary alignment of the driving section, the alignment difficulty between the docking end 120241 and the second shaft end 12015 and the seat body 141 is improved, so as to improve the installation convenience and thus improve the user experience.

[0301] Meanwhile, since the length of the driving section of the second shaft end 12015 is greater than that of the docking end 120241, during the process of installing the bracket assembly 120 with the cleaning member 110 into the receiving cavity 190, the driving section and the docking end 120241 with different lengths have an anti-misoperation effect, which can prevent the user from installing the bracket assembly 120 with the cleaning member 110 in the receiving cavity 190 in the reverse direction, thereby increasing the probability of the user accurately installing the bracket assembly 120.

[0302] In addition, the relationship of the length ratio between A and B can limit the axial mating length between the second shaft end 12015 and the first connecting shaft 12001. Since the longer the dimension A is, it indicates that the longer the dimension that the second shaft end 12015 can be inserted into the first connecting shaft 12001 is. Therefore, under the condition that the number of sides of the plugging blind hole 12002 remains unchanged, the mating contact area between the second shaft end 12015 and the plugging blind hole 12002 on the first connecting shaft 12001 is larger, which is more beneficial to improving the stability of power transmission between the second shaft end 12015 and the first connecting shaft 12001. Therefore, restricting the dimension A can prevent the plugging dimension between the second shaft end 12015 and the first connecting shaft 12001 from being too short, which affects the stability of power transmission between the first roller 1201 and the first connecting shaft 12001.

[0303] Please refer to Figure 77 and Figure 78 , when the length of the driving section is greater than that of the docking end 120241, the inclined surface section 1434 of the abutting portion 1431 includes a first inclined surface section 14341 and a second inclined surface section 14342. The angle between the first inclined surface section 14341 and the vertical plane passing through the axis of the first roller 1201 is greater than the angle between the second inclined surface section 14342 and the vertical plane passing through the axis of the first roller 1201. The second support seat 12012 is provided with a first docking inclined surface 120126 corresponding to the first inclined surface section 14341, and the fourth support seat 12024 is provided with a second docking inclined surface 120242 corresponding to the second inclined surface section 14342. When the abutting portion 1431 is inserted between the second support seat 12012 and the fourth support seat 12024, the first docking inclined surface 120126 fits with the first inclined surface section 14341, and the second docking inclined surface 120242 fits with the second inclined surface section 14342. It should be noted that the first docking inclined surface 120126 and the third guiding inclined surface 1204 of the second support seat 12012 are the same inclined surface, and the second docking inclined surface 120242 and the third guiding inclined surface 1204 of the fourth support seat 12024 are the same inclined surface.

[0304] The inclined surface length of the first inclined surface segment is greater than that of the second inclined surface segment. Along the axial direction of the first roller 1201, the distance between the end of the first connecting shaft 12001 away from the seat body 141 and the end of the second outer support member 143 away from the seat body 141 is less than the distance between the end of the second mounting hole away from the seat body 141 and the end of the second outer support member 143 away from the seat body 141. The length of the first roller 1201 is less than that of the second roller 1202, and the end face of the first roller 1201 away from the seat body 141 is flush with the end face of the second roller 1202 away from the seat body 141. It should be noted that the first roller 1201 here refers to the roller body excluding the first shaft end 12014 and the second shaft end 12015, and the second roller 1202 refers to the roller body excluding the third shaft end 12025 and the fourth shaft end 12026.

[0305] After such a setting, along the axial direction of the first roller 1201, the width of the part of the second outer support member 143 corresponding to the second support seat 12012 can be made greater than the width of the part of the second outer support member 143 corresponding to the first support seat, so that the end of the extended first connecting shaft 12001 away from the seat body 141 can be approximately flush with the end of the first inclined surface segment close to the seat body 141, thereby providing space for the extension of the first connecting shaft 12001 and the driving segment, and enabling the second support seat 12012 to have a clearance fit with the end face of the first connecting shaft 12001 away from the seat body 141, realizing the compactness of the structure.

[0306] Considering the connection efficiency between the second support seat 12012 and the first bracket 121, optionally, in an embodiment, please refer to Figure 72 , the second support seat 12012 is snap-connected to the first bracket 121. There can be various snap-connection methods. For example, it can be a snap-fit structure of a slot and a block. A slot is provided on one of the first bracket 121 and the second support seat 12012, and a matching block is provided on the other. The block is usually designed to be convex, and the slot is concave, and the two are snap-fitted through shape matching. It can also be a snap-fit structure of an elastic buckle and a snap-fit boss or groove. An elastic buckle is provided on one of the first bracket 121 and the second support seat 12012, and a corresponding snap-fit boss or groove is provided on the other. Through the deformation of the elastic buckle, it is snapped into the corresponding boss or groove, and the snap connection is fixed by using the elastic restoring force. By snap-connecting the second support seat 12012 to the first bracket 121, the assembly process can be simplified without using additional fasteners, thereby improving the connection efficiency between the second support seat 12012 and the first bracket 121, and reducing the assembly time and operation complexity.

[0307] Specifically, in this embodiment, please refer to Figures 73 to 76, a first mating portion 1218 is provided on the bracket body. Specifically, the first mating portion 1218 is provided on the first bracket 121 and extends along the length direction of the first bracket 121. A first mating groove 120121 is provided on the second support seat 12012, and the shape of the first mating groove 120121 matches that of the first mating portion 1218. The first mating portion 1218 can be slidably inserted into the first mating groove 120121 along the length direction of the first bracket 121, and the first mating portion 1218 and the first mating groove 120121 are butt-connected in the length direction of the first bracket 121. The first mating groove 120121 includes two relatively arranged groove side walls 120122 and a groove bottom wall 120123 connecting the two groove side walls 120122. When the first mating portion 1218 is inserted into the first mating groove 120121, the two groove side walls 120122 are respectively abutted against the two side surfaces of the first mating portion 1218, and at the same time, the groove bottom wall 120123 is abutted against the bottom surface of the first mating portion 1218, so as to realize the precise plug-in positioning of the second support seat 12012 in the width direction and height direction of the first bracket 121, ensuring the stability and reliability of the connection.

[0308] By providing the first mating portion 1218 and the first mating groove 120121 and making the first mating portion 1218 and the first mating groove 120121 slidably inserted, not only can the accuracy and stability of the assembly between the first bracket 121 and the second support seat 12012 be ensured, but also the connection efficiency can be improved, facilitating the installation and disassembly between the second support seat 12012 and the first bracket 121. At the same time, since the first mating portion 1218 is slidably inserted into the first mating groove 120121 along the length direction of the first bracket 121, when the first roller 1201 needs to be installed on the first bracket 121, the first shaft end 12014 can be first inserted into the first support seat 12011, and then the second shaft end 12015 can be inserted into the second support seat 12012 along the axial direction of the first roller 1201. And during the insertion process, the plug-in between the first mating groove 120121 and the first mating portion 1218 can be completed at the same time. Such an operation can simplify the assembly steps, save the assembly time, and improve the assembly efficiency of the overall structure.

[0309] Optionally, in an embodiment, please continue to refer to Figures 73 to 76, the second support base 12012 further includes a second mating groove 120124 which penetrates through the bottom wall 120123 of the groove, and a third buckle 120125 is provided on the side wall of the second mating groove 120124. It should be noted that the third buckle 120126 can be provided on only one side wall of the second mating groove 120124, or on both side walls. Optionally, in this embodiment, the third buckles 120126 are provided on both side walls. A second mating portion 1219 is further provided on the bracket body. Specifically, the second mating portion 1219 is provided on the first bracket 121, and the second mating portion 1219 is connected to the first mating portion 1218. A first groove 12192 matching the third buckle 120126 is provided on the side wall of the second mating portion 1219. When the second support base 12012 is inserted into the first bracket 121, that is, when the first mating portion 1218 is inserted into the first mating groove 120121, each side of the third buckle 120126 is correspondingly snapped into the first groove 12192 on the same side to form a limit fixation for the connection between the second support base 12012 and the bracket body.

[0310] With this arrangement, when the second support base 12012 is inserted into the first bracket 121, the third buckle 120126 and the first groove 12192 are engaged with each other, which can further improve the positioning connection of the second support base 12012 in the length direction of the first bracket 121 and is beneficial to improving the stability of the insertion of the second support base 12012 into the first bracket 121.

[0311] Optionally, in an embodiment of the present invention, please refer to Figures 73 to 76, on one side of the first support 121 facing the first roller 1201, there is an avoidance arc surface 12193, and the avoidance arc surface 12193 is adapted to the outer peripheral surface of the first roller 1201. At one end of the avoidance arc surface 12193 close to the second support base 12012, there are two notches 12194, and the two notches 12194 are respectively located on both sides in the radial direction of the avoidance arc surface 12193. At one end of the second support base 12012 facing the first support 121, there are two transition arc surfaces 12195, and the two transition arc surfaces 12195 respectively match the two notches 12194. When the second support base 12012 is inserted into the first support 121, the two transition arc surfaces 12195 are respectively filled at the two notches 12194 to form an arc connection with the avoidance arc surface 12193. With such a setting, through the cooperation of the avoidance arc surface 12193, the notches 12194 and the transition arc surfaces 12195, it can be ensured that the first roller 1201 will not interfere with the second support base 12012 and the first support 121 during the rotation process. At the same time, when the second support base 12012 is inserted into the first support 121, the cooperation between the transition arc surface 121965 and the notch 12194 can achieve a smooth transition, and can also improve the compactness of the overall structure and enhance the aesthetics of the overall structure.

[0312] It should be noted that the insertion structure between the fourth support base 12024 and the second support 122 is the same as the insertion structure between the second support base 12012 and the first support 121 in the above embodiment, and will not be described repeatedly here.

[0313] In order to improve the cleaning effect of the cleaning member 110 and reduce the replacement frequency of the cleaning member 110, optionally, in an embodiment of the present invention, please refer to Figure 30 and Figure 31 , the cleaning assembly 100 further includes a fluffing roller 170, the fluffing roller 170 is rotatably installed in the receiving cavity 190 and is in interference contact with the outer surface of the cleaning member 110. The fluffing roller 170 is arranged parallel to the first roller 1201 and the second roller 1202. The fluffing roller 170 includes a roller shaft 171 and fluffing hooks 172, the connecting ends of the fluffing hooks 172 are fixed to the roller shaft 171, the roller shaft 171 is arranged along the length direction of the cleaning member 110, and the free ends of the fluffing hooks 172 are in a bent shape. The bending direction of the free ends of the fluffing hooks 172 is the same as the rotation direction of the roller shaft 171, so it is easier to turn up the fluff on the surface of the rotating cleaning member 110, so that the cleaning member 110 can always maintain a fluffy state during the cleaning process, thereby improving the cleaning effect.

[0314] Please refer to Figure 80 , Figure 81 , Figure 82 and Figure 87, the roller shaft 171 of the fluffing roller 170 includes a first support end 173 and a second support end 174. The first support end 173 is disposed at one end of the roller shaft 171 away from the seat body 141 and is rotatably connected to the housing 180. The first support end 173 can be directly rotatably connected to the housing 180 or indirectly rotatably connected to the housing 180 through other components. Optionally, in this embodiment, please refer to Figures 83 to 86 , the fluffing roller 170 further includes a connecting member 175. The connecting member 175 is disposed in the receiving cavity 190 and is fixedly connected to the housing 180. The connecting member 175 is provided with a mounting hole 1751, and a sixth bearing 12008 is installed in the mounting hole 1751. The first support end 173 is a rotating shaft structure, and the first support end 173 is installed in interference fit with the sixth bearing 12008, so as to realize the rotational connection of the first support end 173 relative to the housing 180.

[0315] Please refer to Figure 88 , the gear assembly 162 includes a third gear structure 1625. The second gear 16232 on the output shaft of the first gear structure 1623 is in transmission connection with the third gear structure 1625. When the first gear structure 1623 rotates, in addition to driving the second gear structure 1624 to rotate, it also drives the third gear structure 1625 to rotate. The output end of the third gear structure 1625 forms the second output end 1622 of the gear assembly 162, and the second output end 1622 is provided with a second output gear 16221. Among them, the third gear structure 1625 is a gear train structure.

[0316] Please refer to Figure 87 , the second support end 174 is disposed at one end of the roller shaft 171 close to the seat body 141 and is fixedly connected to the second output gear 16221. Specifically, the fluffing roller 170 further includes a transfer shaft 176, and the seat body 141 further includes a third mounting hole 1410. The transfer shaft 176 is rotatably connected to the third mounting hole 1410 through a seventh bearing 12009. One end of the transfer shaft 176 extends to the outside of the receiving cavity 190 and is fixedly connected to the second output gear 16221, and the other end of the transfer shaft 176 extends to the inside of the receiving cavity 190 and is provided with a first blind hole 1761. The first blind hole 1761 is a polygonal hole structure, such as a quadrilateral hole, a hexagonal hole, an octagonal hole, etc. The second support end 174 is a multi-prism structure corresponding to the first blind hole 1761. The second support end 174 is inserted into the first blind hole 1761 to realize the fixed connection between the second support end 174 and the transfer shaft 176, and further realize the fixed connection between the roller shaft 171 and the second output gear 16221. When the first driving member 161 rotates, it drives the second output gear 16221 to rotate, and the rotation of the second output gear 16221 drives the second support end 174 to rotate, and further drives the fluffing roller 170 to rotate relative to the housing 180.

[0317] The length of the fluffing roller 170 is greater than or equal to the length of the cleaning member 110, so that the fluffing roller 170 can cover the cleaning member 110 in the length direction of the cleaning member, and the entire working area of the cleaning member 110 can be fluffed by the fluffing roller 170.

[0318] Of course, in other embodiments, the length of the fluffing roller 170 may also only cover a part of the length of the cleaning member 110, which can also play a role in local fluffing.

[0319] By providing the fluffing roller 170, the fluffing roller 170 can perform a fluffing action on the cleaning assembly 100 during the cleaning operation of the cleaning assembly 100, so that the cleaning assembly 100 can be continuously in an efficient cleaning state, and the cleaning efficiency of the cleaning assembly 100 can be improved. At the same time, by driving the cleaning assembly 100 and the fluffing roller 170 to rotate by the same motor, the assembly space can be saved and the production cost of the cleaning assembly 100 can be reduced.

[0320] For the convenience of disassembling and assembling between the fluffing roller 170 and the housing 180, optionally, in another embodiment of the present invention, please refer to Figures 83 to 86 , the connecting member 175 is snap-connected to the housing 180. Specifically, the connecting member 175 includes a hook portion 1752 and a convex portion 1753, and the hook portion 1752 and the convex portion 1752 are arranged at an angle on the outer periphery of the mounting hole 1751. The housing 180 includes a hook groove 1804 and a groove portion 1805. The hook groove 1804 extends along the rotation direction of the fluffing roller 170. The hook portion 1752 matches the hook groove 1804, and the convex portion 1753 matches the groove portion 1805. When installing the connecting member 175, first snap the hook portion 1752 into the hook groove 1804, and then rotate the connecting member 175 along the hook groove 1804 so that the convex portion 1753 is correspondingly snapped into the groove portion 1805 to achieve the snap connection between the connecting member 175 and the housing 180. Such a setting can not only achieve a stable and reliable snap connection between the connecting member 175 and the housing 180, but also simplify the installation process and improve the assembly efficiency between the fluffing roller 170 and the housing 180 because no additional connecting parts are introduced.

[0321] It should be noted that the rotation direction of the fluffing roller 170 and the rotation direction of the cleaning member 110 can be the same or opposite. Optionally, in this embodiment, the rotation direction of the fluffing roller 170 is different from the rotation direction of the cleaning member 110. With such a setting, when the free end of the fluffing roller 170 moves relative to the cleaning member 110, it is easier to turn up the cleaning member 110, which is beneficial to improving the fluffing effect of the cleaning member 110.

[0322] Under the condition of meeting the requirements of the transmission torque and transmission ratio of the second gear structure 1624 and the third gear structure 1625, the number of gears of the second gear structure 1624 and the number of gears of the third gear structure 1625 are not limited. Optionally, in an embodiment of the present invention, please refer to Figure 88 , the number of gears of the second gear structure 1624 is greater than the number of gears of the third gear structure 1625. With such a setting, different output speeds and output torques can be achieved at the first output end 1621 and the second output end 1622, so as to better meet the requirements of the driving torque and rotational speed of the first roller 1201 and the fluffing roller 170.

[0323] In order to achieve different rotational directions of the fluffing roller 170 and the cleaning member 110, optionally, in an embodiment, please refer to Figure 88 , the number of gears of one of the second gear structure 1624 and the third gear structure 1625 is odd, and the number of gears of the other is even. For example, the number of gears of the second gear structure 1624 can be odd and the number of gears of the third gear structure 1625 can be even. It can also be that the number of gears of the second gear structure 1624 is even and the number of gears of the third gear structure 1625 is odd. With such a setting, different rotations of the output ends of the second gear structure 1624 and the third gear structure 1625 can be achieved, that is, different rotation directions of the first output end 1621 and the second output end 1622 can be achieved, so that different rotation directions of the fluffing roller 170 and the cleaning member 110 can be achieved.

[0324] Under the condition that the driving structure 160 drives the first roller 1201 to rotate, optionally, in an embodiment of the present invention, please refer to Figure 53 , the outer peripheral surface at the contact position between the first roller 1201 and the cleaning member 110 is made of rubber material. With such a setting, since the rubber material has a high friction coefficient, slippage between the cleaning member 110 and the first roller 1201 can be reduced, ensuring that the cleaning member 110 can rotate stably with the first roller 1201, which is beneficial to improving the cleaning effect.

[0325] Optionally, please refer to Figure 53, in an embodiment of the present invention, the first roller 1201 includes a first driving roller 120001 and a second driving roller 120002, and the first driving roller 120001 and the second driving roller 120002 are respectively arranged at both ends of the abutting section 1203 of the first roller 1201. In one embodiment, the first driving roller 120001 and the second driving roller 120002 can be two independently arranged shaft sections, and a detachable connection can be achieved between the two through a coupling, a bearing housing, etc. In this way, the weights of the first driving roller 120001 and the second driving roller 120002 can be flexibly prepared according to the requirements of gravity distribution, so the design is more flexible. In another embodiment, the first driving roller 120001 and the second driving roller 120002 can also share a common inner core and are non-detachable from each other. In this way, the assembly of the first roller 1201 can be facilitated and the assembly efficiency can be improved.

[0326] Similarly, the second roller 1202 further includes a first driven roller 120003 and a second driven roller 120004, and the first driven roller 120003 and the second driven roller 120004 are respectively arranged at both ends of the abutting section 1203 of the second roller 1202. In one embodiment, the first driven roller 120003 and the second driven roller 120004 can be two independently arranged shaft sections, and a detachable connection can be achieved between the two through a coupling, a bearing housing, etc. In this way, the weights of the first driven roller 120003 and the second driven roller 120004 can be flexibly prepared according to the requirements of gravity distribution, so the design is more flexible. In another embodiment, the first driven roller 120003 and the second driven roller 120004 can also share a common inner core and are non-detachable from each other. In this way, the assembly of the second roller 1202 can be facilitated and the assembly efficiency can be improved.

[0327] Optionally, in this embodiment, please refer to Figure 55, the first roller 1201 includes a first inner core 120005, which is made of a metal material. The first inner core 120005 is coated with an outer coating. The outer coating on the first inner core 120005 includes a first outer coating 120051 and a second outer coating 120052. The first outer coating 120051 and the corresponding position of the first inner core 12005 form a first driving roller 120001, and the second outer coating 120052 and the corresponding position of the first inner core 12005 form a second driving roller 120002. Both the first outer coating 120051 and the second outer coating 120052 are made of a soft rubber material, and the soft rubber material can be a silicone rubber, rubber or other materials. It should be noted that, in order to facilitate the molding of the first outer coating 120051 and the second outer coating 120052 on the first inner core 12005, both ends of the first outer coating 120051 and both ends of the second outer coating 120052 are provided with shaping members (not shown in the figure), and the shaping members are made of a hard rubber material. The hard rubber material can be polyvinyl chloride, polypropylene, etc. With this arrangement, the first outer coating 120051 and the second outer coating 120052 made of a soft rubber material can have a relatively large frictional force, improving the transmission stability between the cleaning member 110 and the first driving roller 120001 and the second driving roller 120002. On the other hand, it can also reduce the manufacturing cost and overall quality of the first roller 1201.

[0328] Of course, in other embodiments, the materials of the first outer coating 120051 and the second outer coating 120052 can also be a hard rubber material or a metal material, as long as they can drive the cleaning member 110 to rotate when the first roller 1201 rotates, so that the cleaning assembly 100 can perform normal cleaning operations.

[0329] Considering that the cleaning assembly 100 is provided with a driving structure 160 and a seat body 141 at one end close to the seat body 141, this will cause a weight deviation at both ends of the cleaning assembly 100 in the length direction. During the cleaning operation, it will cause unequal cleaning forces between the cleaning member 110 and the surface to be cleaned, affecting the uniformity of the cleaning effect. Based on this, optionally, in an embodiment of the present invention, please refer to Figure 31 and Figure 56, the second roller 1202 includes a second inner core 12006, which is made of a metal material and integrally formed between a third shaft end 12025 and a fourth shaft end 12026. An outer layer is wrapped around the second inner core 12006, and the outer layer on the second inner core 12006 includes a third outer layer 120061 and a fourth outer layer 120062. The fourth outer layer 120062 is disposed at one end of the second roller 1202 away from the seat body 141. The third outer layer 120061 and the second inner core 12006 at the corresponding position form a first driven roller 120003, and the fourth outer layer 120062 and the second inner core 12006 at the corresponding position form a second driven roller 120004. The third outer layer 120061 is made of a soft rubber material, and the soft rubber material can be a material such as silica gel or rubber. The fourth outer layer 120062 is made of a metal material. The fourth outer layer 120062 can be the same metal material as the second inner core 12006 or different types of metal materials, and this embodiment does not limit this.

[0330] It should be noted that, for the convenience of forming the third outer layer 120061 on the second inner core 12006, shaping members are also provided at both ends of the third outer layer 120061, and the shaping members are made of a hard rubber material. The hard rubber material can be polyvinyl chloride, polypropylene, etc. With this setting, on the one hand, the third outer layer 120061 made of a soft rubber material can have a relatively large frictional force to ensure that there is sufficient driving frictional force between the second roller 1202 and the cleaning member 110, reduce the probability of slipping between the second roller 1202 and the cleaning member 110, and improve the transmission stability of the cleaning member 110. On the other hand, since the fourth outer layer 120062 is made of a metal material, under the conditions of the same diameter and the same length, the mass of the second driven roller 120004 is greater than the mass of the first driven roller 120003, which can increase the weight of one end of the second roller 1202 away from the seat body 141, and thus is beneficial to improving the weight deviation at both ends of the cleaning assembly 100 in the length direction and improving the overall operation stability of the cleaning assembly 100 and the consistency of the cleaning effect.

[0331] To improve the stability when the first roller 1201 and the second roller 1202 drive the cleaning member 110 to rotate, and at the same time to improve the flatness of the fit between the side of the cleaning member 110 facing the ground and the ground, the outer diameters of the outer layers on the first inner core 120005 and the second inner core 120006 are equal.

[0332] To further improve the weight deviation generated by the cleaning assembly 100, optionally, in another embodiment of the present invention, please refer to Figure 89, the cleaning assembly 100 further includes a counterweight 1806, and the counterweight 1806 is disposed at an end of the housing 180 away from the drive mechanism 160. The counterweight 1806 may be disposed on a side of the housing 180 facing the cleaning member 110, or may be disposed on a side of the housing 180 facing away from the cleaning member 110.

[0333] Optionally, in the present embodiment, the counterweight 1806 is disposed on a side of the housing 180 away from the cleaning member 110, that is, on the outer side of the housing 180. Such a setting facilitates the installation of the counterweight 1806 on the housing 180. The counterweight 1806 may be snap-connected to the housing 180, or may be fixedly connected to the housing 180 by bolts. Optionally, in the present embodiment, the counterweight 1806 is fixedly connected to the housing 180 by bolts. The counterweight 1806 may be made of a metal material or a non-metal material, as long as it can meet the counterweight requirements, and there is no limitation thereto. By providing the counterweight 1806 at an end of the housing 180 away from the seat body 141, the weight of the cleaning assembly 100 at the end away from the drive mechanism 160 can be increased, thereby further improving the problem of uneven weight distribution caused by the installation of the drive structure 160 at the seat body 141 end. Therefore, this design can balance the overall center of gravity of the cleaning assembly 100, reduce vibration and offset during operation, and further improve the stability of the overall operation of the cleaning assembly 100 and the consistency of the cleaning effect.

[0334] Under the condition of meeting the counterweight requirements of the counterweight 1806, the specific setting position and the number of the counterweight 1806 are not limited. Optionally, please refer to Figure 89 and Figure 164 , in an embodiment, the counterweight 1806 includes a first counterweight 18061. The first counterweight 18061 may be a plate-like structure, or may be a block-like structure, a columnar structure, etc. In the present embodiment, the first counterweight 18061 is a flat plate structure. The first counterweight 18061 is disposed at an end of the housing 180 away from the drive mechanism 160 and covers the avoidance groove 1802 on the housing 180. With such a setting, the first counterweight 18061 can not only play a good counterweight role, but also act as a cover plate to block the structure of the avoidance groove 1802 provided on the housing 180, improving the aesthetics of the overall structure.

[0335] Please refer to Figure 165, in another embodiment, the counterweight 1806 includes, in addition to the first counterweight 18061, a second counterweight 18062 and a third counterweight 18063. The second counterweight 18062 and the third counterweight 18063 are disposed on a side of the first counterweight 18061 facing the drive mechanism 160, and the second counterweight 18062 and the third counterweight 18063 are disposed close to the first counterweight 18061. The second counterweight 18062 and the third counterweight 18063 are arranged along the width direction of the housing 180. The whole formed by the first counterweight 18061, the second counterweight 18062 and the third counterweight 18063 is located at an end of the housing 180 away from the drive mechanism 160. The masses of the second counterweight 18062 and the third counterweight 18063 may be the same or different. In the actual design process, it is necessary to determine according to the overall mass balance requirements of the cleaning assembly 100.

[0336] By providing the first counterweight 18061, the second counterweight 18062 and the third counterweight 18063, a distributed layout of the counterweight mass on the housing 180 can be achieved, so as to more flexibly optimize the overall counterweight performance of the cleaning assembly 100. At the same time, by precisely regulating the mass distribution of each counterweight 1806, a variety of counterweight combination schemes can be formed, and then the vibration characteristics under different working conditions can be accurately adjusted, significantly improving the adjustability and optimization efficiency of the dynamic balance of the cleaning assembly 100.

[0337] Please refer to Figures 90 to 118 , in an embodiment of the present invention, a cleaning assembly 100 is further provided. The cleaning assembly 100 includes a first connecting member 301, a second connecting member 302, and a cleaning mechanism 303.

[0338] The first connecting member 301 is detachably connected to the bottom of the fuselage 200 to achieve a detachable connection between the cleaning assembly 100 and the fuselage 200. The detachable connection method may be a bolt detachable connection or a snap detachable connection, etc. Specifically, in this embodiment, please refer to Figures 90 to 93, the body 200 includes a base 250. The base 250 is provided with a cleaning component installation cavity 260 for accommodating the cleaning component 100. The upper wall of the cleaning component installation cavity 260 is provided with a plurality of installation slots 261 and a plurality of installation through holes 262. One side of the first connecting member 301 facing the base 250 is provided with a plurality of installation screw holes 3016 and a plurality of installation buckles 3017 extending towards the base 250. The plurality of installation screw holes 3016 correspond to the plurality of installation through holes 262 one by one for installing fasteners, such as bolts, screws, etc. from one side of the base 250. The plurality of installation slots 261 correspond to the plurality of installation buckles 3017 one by one. The installation buckles 3017 are correspondingly clamped in the installation slots 261 to form a pre-installation relationship between the first connecting member 301 and the base 250, facilitating the subsequent installation of fasteners in the installation through holes 262 and the installation screw holes 3016.

[0339] Please refer to Figure 94 , the second connecting member 302 is slidably installed on the first connecting member 301. There are various ways of slidable installation. For example, one of the first connecting member 301 and the second connecting member 302 can be provided with a sliding groove, and the other can be provided with a sliding block, and the sliding connection between the second connecting member 302 and the first connecting member 301 is realized through the mutual cooperation of the sliding groove and the sliding block. It can also be that one of the first connecting member 301 and the second connecting member 302 is provided with a guide rod, and the other is provided with a guide sleeve, and the sliding connection between the second connecting member 302 and the first connecting member 301 is realized through the mutual cooperation of the guide rod and the guide sleeve.

[0340] Please refer to Figures 94 to 96 , the cleaning mechanism 303 is movably installed on the second connecting member 302. The cleaning mechanism 303 has a lifting position and a mopping position. It should be noted that the cleaning mechanism 303 can also include all the components on the cleaning component 100 in the above embodiments, such as the cleaning member 110, the bracket assembly 120, the pulling member 130, the outer support assembly 140, and other components installed on the outer support assembly 140 and the bracket assembly 120. However, those skilled in the art can understand that in some other embodiments, the above outer support assembly 140 may not be provided, and it can be realized through a conventional tensioning structure of the cleaning member 110.

[0341] Please refer to Figure 97 , a lifting mechanism 304 is provided between the cleaning mechanism 303 and the second connecting member 302. During the process of the second connecting member 302 sliding relative to the first connecting member 301, the lifting mechanism 304 drives the cleaning mechanism 303 to perform a lifting movement so that the cleaning mechanism 303 is in the lifting position or the mopping position. Exemplarily, as Figure 40 shown, when the cleaning component 100 is in the mopping state, the cleaning mechanism 303 descends under the action of the lifting mechanism 304 and contacts the ground to clean the ground, that is, the cleaning mechanism 303 is in the mopping position. Another example is, asFigure 39 As shown, when the cleaning assembly 100 travels to the cleaning area, the cleaning mechanism 303 is lifted by the lifting mechanism 304 and keeps a certain distance from the ground, that is, the cleaning mechanism 303 is in the lifted position.

[0342] It should be noted that in this embodiment, the sliding direction of the second connecting member 302 relative to the first connecting member 301 is a horizontal direction perpendicular to the lifting direction of the cleaning mechanism 303. The lifting direction of the cleaning mechanism 303 is the height direction of the cleaning assembly 100, as shown by the Z1 axis in Figure 96 the figure. The specific sliding direction of the second connecting member 302 relative to the first connecting member 301 is not limited. For example, it can slide along the length direction of the cleaning mechanism 303, or along the width direction of the cleaning mechanism 303, etc. Optionally, in this embodiment, the second connecting member 302 slides horizontally relative to the first connecting member 301 along the length direction of the cleaning mechanism 303. The sliding direction of the second connecting member 302 is shown by the X1 axis in Figure 96 the figure. At the same time, the sliding direction of the second connecting member 302 is also the length direction of the second connecting member 302. This can effectively utilize the dimension in the length direction of the cleaning mechanism 303, reduce the width dimension of the cleaning assembly 100 occupied during the sliding process of the second connecting member 302, and is more conducive to the compact design of the structure.

[0343] The lifting mechanism 304 can be an inclined plane and slider structure. An inclined plane is provided on one of the second connecting member 302 and the cleaning mechanism 303, and a slider is provided on the other. During the sliding of the second connecting member 302 relative to the first connecting member 301, the slider slides along the inclined plane, thereby realizing the lifting of the cleaning mechanism 303 along the second connecting member 302. The lifting mechanism 304 can also be a rope and pulley structure. A pulley is provided on the first connecting member 301. One end of the rope is connected to the cleaning mechanism 303 below the pulley, and the other end is connected to the second connecting member 302 through the pulley. During the horizontal sliding of the second connecting member 302 relative to the first connecting member 301, the second connecting member 302 pulls the rope to stretch up and down along the pulley, thereby driving the cleaning mechanism 303 connected to the rope to perform a lifting motion.

[0344] The cleaning assembly 100 of the present invention is provided with a lifting mechanism 304. During the sliding of the second connecting member 302 relative to the first connecting member 301, the lifting mechanism 304 can drive the cleaning mechanism 303 to perform a lifting motion, so that the cleaning mechanism 303 can be switched between a lifted position and a mopping position. With such a setting, on the one hand, since the lifting mechanism 304 can drive the cleaning mechanism 303 to perform a lifting motion, the cleaning assembly 100 can better meet various application scenarios. For example, during the cleaning operation, when the body 200 passes over a carpet, the cleaning mechanism 303 can be switched to the lifted position to avoid wetting the carpet; or, in scenarios such as obstacle crossing or returning to the base station, the cleaning mechanism 303 can also be switched to the lifted position to prevent the cleaning mechanism 303 from being stuck by an obstacle and detaching from the body 200. On the other hand, since the lifting mechanism 304 can drive the cleaning mechanism 303 to perform a lifting motion during the sliding of the second connecting member 302 relative to the first connecting member 301, the sliding of the second connecting member 302 can be directly used to drive the operation of the lifting mechanism 304, without the need to additionally provide an independent lifting motor or hydraulic system. Therefore, the device structure can be simplified and the overall weight of the cleaning assembly 100 can be reduced.

[0345] Please refer to Figures 97 to 100 , in an embodiment of the present invention, the lifting mechanism 304 includes a lifting surface 3041 and an abutting portion 3042. The lifting surface 3041 is provided on the second connecting member 302, and the abutting portion 3042 is provided on the side of the cleaning mechanism 303 facing the first connecting member 301. The lifting surface 3041 is supported below the abutting portion 3042, and the abutting portion 3042 is pressed against the lifting surface 3041 by the gravity of the cleaning mechanism 303. The abutting portion 1431 moves along the lifting surface 3041 to drive the cleaning mechanism 303 to achieve a lifting motion.

[0346] The number of the lifting surface 3041 and the abutting portion 3042 can be set according to actual needs. However, in this embodiment, please refer to Figure 94 , Figure 97 and Figure 98 , in order to improve the stability and lifting accuracy of the cleaning mechanism 303, along the length direction of the cleaning mechanism 303, two abutting portions 3042 are spaced apart in the middle area of the cleaning mechanism 303, and two corresponding lifting surfaces 3041 are provided on the second connecting member 302, and the inclination directions of the two lifting surfaces 3041 are the same. In order to facilitate the forming and positioning of the two lifting surfaces 3041, in this embodiment, the two lifting surfaces 3041 are along the second connecting member 302 (such as Figure 102They are arranged in an array in the length direction (as shown by the X2 axis) on the second connecting member 302. The two abutting portions 3042 respectively abut against the two lifting surfaces 3041, thereby forming two lifting points in the length direction for the cleaning mechanism 303. With this arrangement, since the cleaning mechanism 303 is jointly affected by the two lifting points during the lifting process, the weight of the cleaning mechanism 303 can be effectively dispersed, avoiding tilting or shaking caused by single-point force, and thus significantly improving the stability of the lifting motion.

[0347] The specific structures of the lifting surface 3041 and the abutting portion 1431 can have various design forms. For example, the lifting surface 3041 can be an inclined surface, an arc surface, or a combined structure of an inclined surface and an arc surface, etc. The abutting portion 3042 can be a structure such as an inclined block, an arc-shaped block, a pin shaft, etc. connected to the cleaning mechanism 303. When the abutting portion 3042 moves along the lifting surface 3041, the abutting portion 3042 and the lifting surface 3041 can be in rolling contact or sliding contact, and this embodiment is not limited thereto.

[0348] By providing the lifting surface 3041 and the abutting portion 3042, the lifting function of the cleaning mechanism 303 can be realized by the abutting and cooperation between the lifting surface 3041 and the abutting portion 3042. This structural design is simple and convenient to process. At the same time, since the abutting portion 3042 is pressed against the lifting surface 3041 by the gravity of the cleaning mechanism 303, this design enables the lifting mechanism 304 to be self-locked by the gravity of the cleaning mechanism 303 in the non-driven state, preventing the cleaning mechanism 303 from accidentally sliding or falling, and further improving the stability of the lifting operation of the cleaning mechanism 303. Moreover, the design of gravity pressing can also ensure the close contact between the abutting portion 3042 and the lifting surface 3041. Even when the load of the cleaning mechanism 303 changes, the stable abutting between them can be maintained, avoiding the sliding or vibration of the cleaning mechanism 303 due to poor contact and affecting the cleaning operation.

[0349] Optionally, in an example of the present invention, please refer to Figure 97 and Figure 100 , the second connecting member 302 includes a concave cavity 3021, the concave cavity 3021 is recessed toward the side of the cleaning mechanism 303, and a protruding structure 3022 is provided inside the concave cavity 3021. The protruding structure 3022 connects one side wall body in the length direction of the concave cavity 3021 and the bottom wall of the concave cavity 3021. The length direction of the concave cavity 3021 is consistent with the length direction of the second connecting member 302. The lifting surface 3041 is formed on the outer surface of the protruding structure 3022.

[0350] Please refer to Figure 101 , Figure 102 and Figure 103, two first through grooves 3023 are provided on the bottom wall of the concave cavity 3021. Along the width direction of the concave cavity 3021, the two first through grooves 3023 are respectively arranged on both sides of the convex structure 3022 and both extend along the length direction of the concave cavity 3021. The width direction of the concave cavity 3021 is consistent with the width direction of the second connecting member 302 (as shown by the Y2 axis in Figure 102 ). Please refer to Figure 100 and Figure 103 . On the side of the cleaning mechanism 303 facing the first connecting member 301, two sets of connecting ends 3015 are provided. Each set of connecting ends 3015 correspondingly connects a holding portion 3042, and each set of connecting ends 3015 includes two extending portions 3011. One end of the extending portion 3011 is connected to the side of the cleaning mechanism 303 facing the first connecting member 301. Specifically, the two extending portions 3011 are both arranged on the housing 180. One extending portion 3011 corresponds to one first through groove 3023. The extending portion 3011 is slidably installed in the first through groove 3023 and at least partially extends into the concave cavity 3021. The holding portion 3042 is installed above the lifting surface 3041. Along the width direction of the concave cavity 3021, both ends of the holding portion 3042 are respectively connected to the extending portions 3011 on both sides, thereby realizing the connection between the holding portion 3042 and the cleaning mechanism 303. When the holding portion 3042 moves along the lifting surface 3041, the two extending portions 3011 respectively slide along the first through grooves 3023 at corresponding positions.

[0351] Since the convex structure 3022 connects the side wall and the bottom wall of the concave cavity 3021, and the lifting surface 3041 is formed on the outer surface of the convex structure 3022, the setting of this structure can improve the local support strength and stiffness of the lifting surface 3041, and further can provide stable and reliable support for the holding portion 3042 to ensure that the lifting surface 3041 can have good support stability during long-term use. At the same time, the extending portions 3011 on both sides are respectively connected to both ends of the holding portion 3042, which can form a double-point connection structure to balance the force of the holding portion 3042 and prevent deformation caused by unilateral stress concentration, further improving the abutting stability between the holding portion 3042 and the lifting surface 3041. Moreover, through the cooperation of the extending portion 3011 and the first through groove 3023, it can also play a preliminary guiding role when the lifting surface 3041 and the holding portion 3042 move relative to each other, so that the smoothness of the lifting process of the cleaning mechanism 303 can be improved, and the probability of deviation or shaking can be reduced.

[0352] Optionally, in an example of the present invention, please refer to Figure 100 、 Figure 101 Figure 104, the lifting surface 3041 includes an inclined surface 30411. Along the depth direction of the concave cavity 3021, the inclined surface 30411 inclines from the bottom wall of the concave cavity 3021 towards the opening side of the concave cavity 3021. The inclination angle of the inclined surface 30411 is determined by the lifting distance of the cleaning mechanism 303. Please refer to Figure 103 , the abutting portion 3042 is a pin shaft, and the pin shaft is fixedly connected to the cleaning mechanism 303. Pin shaft mounting holes 30111 are provided on both extension portions 3011, and both ends of the pin shaft are respectively mounted in the pin shaft mounting holes 30111 on the corresponding side. The connection between the pin shaft and the pin shaft mounting hole 30111 includes but is not limited to achieving fixed connection through interference fit of the shaft hole. The outer peripheral surface of the pin shaft abuts against the inclined surface 30411 and slides along the lifting surface 3041.

[0353] In this embodiment, the lifting surface 3041 with an inclined surface structure is adopted, so that the lifting stroke of the cleaning mechanism 303 can be adjusted only by adjusting the inclination angle of the inclined surface 30411. Therefore, it has good design adaptability and can more easily match cleaning mechanisms 303 with a variety of different lifting stroke requirements. At the same time, the abutting portion 3042 is set as a pin shaft, and the pin shaft is fixedly connected to the cleaning mechanism 303, which can effectively reduce the friction generated between the pin shaft and the lifting surface 3041 during mutual movement, facilitating sliding between them. In addition, since the pin shaft does not need to rotate, the connection structure between it and the cleaning mechanism 303 is simpler, which is beneficial to reducing the assembly and manufacturing costs of the cleaning assembly 100.

[0354] In one embodiment, the pin shaft can also be rotatably connected to the cleaning mechanism 303. For example, bearings can be provided in the pin shaft mounting holes 30111 of the extension portion 3011, and both ends of the pin shaft are respectively connected to the pin shaft mounting holes 30111 through bearings, thereby realizing the rotational connection between the pin shaft and the cleaning mechanism 303. With this setting, when the pin shaft moves along the inclined surface 30411, the friction between the two is rolling friction. Therefore, the friction between the two can be reduced, which is beneficial to reducing the energy consumption during the lifting operation of the cleaning mechanism 303 and plays an energy-saving role. At the same time, the wear between the pin shaft and the inclined surface 30411 can also be reduced, which is beneficial to improving the service life of the pin shaft and the inclined surface 30411.

[0355] In another embodiment, the pin shaft can also be composed of a pin shaft body and a bearing sleeved on the outer periphery of the pin shaft body. The pin shaft is fixedly connected to the pin shaft mounting hole, and the bearing is rotatably connected to the pin shaft body. The pin shaft is in rolling contact with the inclined surface through the bearing. This can also achieve rolling friction between the pin shaft and the inclined surface and reduce the friction between the pin shaft and the inclined surface.

[0356] Optionally, in one embodiment, please refer to Figure 107, a raised slide bar 3043 is provided on the inclined surface 30411, and the outer peripheral surface of the pin shaft abuts against the surface of the slide bar 3043. The number of the slide bars 3043 is not limited. Optionally, in this embodiment, two slide bars 3043 are provided on the inclined surface 30411, and the slide bars 3043 are arranged on both sides in the width direction of the inclined surface 30411. Such an arrangement can reduce the contact area between the pin shaft and the inclined surface 30411, thereby also reducing the frictional resistance between the two, making the sliding of the pin shaft smoother.

[0357] To reduce the probability of the pin shaft coming out of the pin shaft mounting hole, optionally, refer to Figure 108 , in an embodiment of the present invention, a first docking hole 3018 is provided on the side wall of the first connecting member 301, a second docking hole 3024 is provided on the side wall of the second connecting member 302, and the first docking hole 3018 and the second docking hole 3024 are arranged on the same side in the width direction of the first connecting member 301. When the pin shaft is at a specified position on the inclined surface 30411, the first docking hole 3018, the second docking hole 3024 and the pin shaft mounting hole 30111 are aligned and communicated with each other to realize the disassembly and assembly of the pin shaft along its own axis direction. When the pin shaft is at a specified position on the inclined surface 30411, the cleaning mechanism 303 is in a transition position between the raised position and the mopping position. Such an arrangement is such that during the operation of the cleaning assembly 100, since the cleaning mechanism 303 stays at the mopping position and the raised position for most of the time, therefore, the cleaning mechanism 303 stays at the transition position other than the mopping position and the raised position for a short time, so the pin shaft hardly stays at the specified position on the inclined surface 30411 for a long time. Such a design can effectively reduce the probability of the pin shaft coming out of the pin seat mounting hole 30111 during the operation, thereby improving the stability and reliability of the overall structure connection.

[0358] Optionally, in an embodiment of the present invention, refer to Figure 100 and Figure 104 , the lifting surface 3041 further includes a first plane 30412 and a second plane 30413, and the first plane 30412 and the second plane 30413 are respectively connected to both ends in the inclined direction of the inclined surface 30411. The first plane 30412 and the second plane 30413 are arranged in parallel, and the first plane 30412 is located on the side of the inclined surface 30411 close to the cleaning mechanism 303, and the distance from the first plane 30412 to the ground is less than the distance from the second plane 30413 to the ground. When the cleaning mechanism 303 is in the lifted position, the abutting portion 3042 stays on the second plane 30413, and when the cleaning mechanism 303 is in the falling position, the abutting portion stays on the first plane 30412. As Figure 100 shown, when the cleaning mechanism 303 is in the mopping position, the abutting portion 3042 abuts against the first plane 30412. As Figure 98As shown, when the cleaning mechanism 303 is in the lifted position, the abutting portion 3042 abuts against the second plane 30413.

[0359] Specifically, please refer to Figure 104 , the first plane 30412 is formed on the bottom wall of the cavity 3021. One end of the first plane 30412 is connected to the wall of one side in the length direction of the cavity 3021, and the other end is connected to one end of the inclined plane 30411 that is closer to the cleaning mechanism 303 in the inclined direction. One end of the second plane 30413 is connected to the other end of the inclined plane 30411 in the inclined direction, and the other end of the second plane 30413 is connected to the other side wall body in the length direction of the cavity 3021.

[0360] It should be noted that, as Figure 100 shown, when the abutting portion 3042 abuts against the first plane 30412, at this time, the extension portion 3011 connected to the abutting portion 3042 stops at one end in the extending direction of the first through groove 3023. Therefore, a limit can be formed on one side in the sliding direction of the abutting position of the abutting portion 3042 on the first plane 30412. As Figure 98 shown, when the abutting portion 3042 abuts against the second plane 30413, at this time, the extension portion 3011 stops at the other end in the extending direction of the first through groove 3023. Therefore, a limit can be formed on the other side in the sliding direction of the abutting position of the abutting portion 3042 on the second plane 30413. Such a setting can play a role in limiting the sliding displacement of the second connecting member 302, reduce the excessive displacement or position deviation that may occur during the sliding process of the second connecting member 302, and ensure its stable and accurate movement within a predetermined range.

[0361] By respectively arranging the first plane 30412 and the second plane 30413 at both ends in the inclined direction of the inclined plane 30411, when the cleaning mechanism 303 is in the mopping position and the lifted position, the abutting portion 3042 can respectively abut against the first plane 30412 and the second plane 30413. This design can utilize the self - gravity of the cleaning mechanism 303 to realize the self - locking between the abutting portion 3042 and the lifting surface 3041. Furthermore, the stability of the cleaning mechanism 303 in the two working states can be improved, and accidental movement or position change caused by external force or vibration can be prevented.

[0362] In some embodiments, please refer to Figures 161 to 163, along the height direction of the second connecting member 302, a shielding portion 3026 is provided on the side of the first through groove 3023 away from the cleaning mechanism 303, and the shielding portion 3026 is located above the first plane 30412 for shielding the extending portion 3011. When the cleaning mechanism 303 is in the mopping position (i.e., the abutting portion 3042 abuts against the first plane 30412), the ground reaction force will cause the cleaning member 110 to have an upward movement tendency. At this time, through the contact cooperation between the shielding portion 3026 and the extending portion 3011, the maximum upward movement stroke of the cleaning member 110 can be effectively limited. This limiting mechanism can ensure that a stable contact pressure is maintained between the cleaning member 110 and the ground, thereby ensuring the consistency of the cleaning effect.

[0363] Please refer to Figure 166 , in another embodiment, a second groove 30261 is provided on the side of the shielding portion 3026 facing the extending portion 3011, and a convex portion 30112 matching the second groove 30261 is provided on the side of the extending portion 3011 facing the shielding portion 3026. When the cleaning mechanism 303 is in the mopping position, the extending portion 3011 moves upward under the push of the ground reaction force, and the convex portion 30112 will be correspondingly stuck into the second groove 30261. This design can limit the movement of the extending portion 3011 in the direction of outward expansion and inward contraction of the cleaning member 110, thereby improving the installation stability of the cleaning member 110 in the horizontal direction relative to the fuselage 200 when in the mopping position. Therefore, the probability of the cleaning member 110 shifting in the horizontal direction during the cleaning operation can be reduced, and the cleaning effect of the cleaning member 110 can be further improved. It should be noted that even without the push of the ground reaction force, the convex portion and the second groove will be slightly stuck, and the slight sticking means that the convex portion 30112 and the second groove 30261 are not tightly stuck.

[0364] Please refer to Figure 166 , an avoidance inclined surface is provided at the end of the shielding portion 3026 facing the second plane 30413. During the process of the abutting portion 3042 moving from the first plane 30412 to the second plane 30413, the avoidance inclined surface can form an avoidance space on the movement path of the extending portion 3011 to ensure the smoothness of the movement of the extending portion 3011.

[0365] In order to improve the sliding accuracy of the second connecting member 302 relative to the first connecting member 301 and reduce the probability of lateral offset during the sliding process, optionally, in an embodiment of the present invention, please refer to Figure 101 , Figure 105 , Figure 109 and Figure 110A second guide assembly 305 is provided between the first connecting member 301 and the second connecting member 302 to guide the second connecting member 302 to slide along the first connecting member 301. The second guide assembly 305 may be a guide rail and a slider structure, one of which is provided on the first connecting member 301, and the other is provided on the second connecting member 302. The sliding between the slider and the guide rail enables the sliding guide between the second connecting member 302 and the first connecting member 301. The second guide assembly 305 may also be a bump and a slide groove structure, one of which is provided on the first connecting member 301, and the other is provided on the second connecting member 302. The sliding between the bump and the slide groove enables the sliding guide between the second connecting member 302 and the first connecting member 301.

[0366] By setting up the second guide component 305, the second guide component 305 can ensure that the second connecting member 302 slides along a predetermined direction relative to the first connecting member 301, reducing the probability of offset or shaking between each other during the sliding process, and further reducing the jamming phenomenon during the sliding process, which is beneficial to improving the smoothness of the sliding of the second connecting member 302.

[0367] Optionally, in one embodiment of the present invention, please refer to Figure 101 , Figure 105 , Figure 109 and Figure 110 The second guide assembly 305 includes a sliding cavity 3051 and a second sliding portion 3052. The sliding cavity 3051 is arranged in the first connecting member 301, and the second sliding portion 3052 is arranged in the second connecting member 302. The second connecting member 302 is arranged in the sliding cavity 3051, and is slidably connected to the sliding cavity 3051 through the second sliding portion 3052. The length direction of the sliding cavity 3051 is consistent with the sliding direction of the second connecting member 302. The two ends of the sliding cavity 3051 in the length direction can be sealed or open, as long as the sliding stroke requirement of the second connecting member 302 relative to the first connecting member 301 is met. Optionally, in this embodiment, Figure 109 As shown, both ends of the sliding cavity 3051 in the extension direction are open, and the second connecting member 302 can move to the outside of the sliding cavity 3051 in the extension direction during the sliding process, such as Figure 105 This arrangement is beneficial to reducing the length of the first connecting member 301 and reducing the overall weight of the cleaning assembly 100.

[0368] See also Figure 105 , Figure 108 and Figure 111, the bottom wall of the second connecting member 302 is in sliding contact with the bottom wall of the sliding cavity 3051. A second through groove 3053 for the extension portion 3011 to pass through is provided on the bottom wall of the sliding cavity 3051, and at least a part of the second through groove 3053 coincides with the first through groove 3023. Along the height direction of the cleaning mechanism 303, the extension portion 3011 sequentially passes through the second through groove 3053 and the first through groove 3023 from bottom to top and then is connected to the abutting portion 3042. Please refer to Figure 101 , Figure 105 and Figure 109 , two side walls of the second connecting member 302 in the width direction respectively form two second sliding portions 3052, and the two second sliding portions 3052 are respectively in sliding contact with two side walls in the width direction of the sliding cavity 3051 (as shown by the Y3 axis in Figure 109 ).

[0369] By providing the sliding cavity 3051 on the first connecting member 301, not only can it play a guiding role in the sliding of the second connecting member 302, but also the setting of the sliding cavity 3051 can increase the overall strength and stiffness of the first connecting member 301 and improve its bearing capacity. At the same time, by arranging the second connecting member 302 in the sliding cavity 3051, the installation space of the cleaning assembly 100 in the height direction can be further reduced, and the compactness of the structural design can be improved.

[0370] Optionally, in an embodiment, please refer to Figure 90 , Figure 94 and Figure 101, the cleaning component installation cavity 260 includes an upper end wall, and the upper end wall is arranged on the side facing the cleaning mechanism 303. One end of the first connecting member 301 away from the cleaning mechanism 303 is connected to the upper end wall to realize the connection between the cleaning component 100 and the fuselage 200. The upper end wall forms an upper block for the sliding cavity 3051, and the second connecting member 302 is clamped between the first connecting member 301 and the upper end wall. On the side surface of the second connecting member 302 away from the cleaning mechanism 303, there is a support strip 3025. The support strip 3025 protrudes towards the upper end wall and extends along the moving direction of the second connecting member 302 relative to the first connecting member 301. One support strip 3025 can be provided, or multiple support strips 3025 can be provided. Optionally, in this embodiment, two support strips 3025 are provided, and the two support strips 3025 are spaced along the width direction of the second connecting member 302. By providing the support strip 3025, on the one hand, the contact surface between the second connecting member 302 and the cleaning component installation cavity 260 can be reduced, and the friction generated between the second connecting member 302 and the cleaning component installation cavity 260 during the movement of the second connecting member 302 can be reduced, making the sliding of the second connecting member 302 smoother. On the second hand, the support strip 3025 is in sliding contact with the upper end wall of the cleaning component installation cavity 260, avoiding the upward movement or arching deformation of the second connecting member 302, and improving the sliding stability of the second connecting member 302 between the upper end wall and the first connecting member 301. On the third hand, the support strip 3025 can also increase the structural strength of the second connecting member 302, reducing the probability of warping or deformation of the second connecting member 302 during use, thereby further improving the smoothness and stability of the sliding of the second connecting member 302 relative to the first connecting member 301.

[0371] Optionally, in another embodiment, the support strip 3025 can also be replaced with a bearing support. The bearing support includes a mounting seat, a connecting shaft and a bearing. The mounting seat is fixedly connected to the side wall of the second connecting member 302 away from the cleaning mechanism 303. The bearing is sleeved on the connecting shaft, and the connecting shaft is fixedly connected to the mounting seat. The outer ring of the bearing is in rolling contact with the upper end wall of the cleaning component installation cavity 260. Multiple bearing supports can be provided, and the bearings of the multiple bearing supports roll along the moving direction of the second connecting member 302. With this setting, the contact friction between the second connecting member 302 and the cleaning component installation cavity 260 can also be reduced, playing a role in improving the smoothness of the movement of the second connecting member 302.

[0372] When the second connecting member 302 slides relative to the first connecting member 301, it can be by manually pushing the second connecting member 302 to make the second connecting member 302 slide relative to the first connecting member 301. It can also be to additionally provide a driving component between the first connecting member 301 and the second connecting member 302, and drive the second connecting member 302 to slide relative to the first connecting member 301 through the driving component. Optionally, in an embodiment of the present invention, please refer to Figure 94 andFigure 97 A driving assembly 306 is provided between the first connecting member 301 and the second connecting member 302. The fixed end of the driving assembly 306 is connected to the first connecting member 301, and the driving end of the driving assembly 306 is connected to the second connecting member 302. When the driving assembly 306 operates, it drives the second connecting member 302 to slide relative to the first connecting member 301. The driving assembly 306 can be any linear driving mechanism such as a motor and a gear-rack structure, a motor and a ball screw structure, a cylinder or a hydraulic cylinder, a flexible cable structure, etc. that can realize the sliding of the second connecting member 302 relative to the first connecting member 301.

[0373] By providing the driving assembly 306, automatic control of the sliding operation of the second connecting member 302 relative to the first connecting member 301 can be realized, thereby improving the operation efficiency and control accuracy. At the same time, since the provided driving assembly 306 can realize the automatic control of the sliding operation of the first connecting member 301, there is no need to reserve manual operation space on the cleaning assembly 100, thereby improving the compactness of the internal structure of the cleaning assembly 100.

[0374] Please refer to Figure 99 、 Figure 110 and Figure 113 Optionally, in an embodiment of the present invention, the driving assembly 306 includes a second driving member 3061, a gear transmission assembly 3062, and a gear-rack transmission assembly 3063. The gear transmission assembly 3062 includes a first gear 30621 and a second gear 30622. The gear-rack transmission assembly 3063 includes a transmission shaft 30631, a third gear 30632, and a rack 30633. The second driving member 3061 is installed on the first connecting member 301. The second driving member 3061 can be any mechanism that can output rotational motion, such as a motor, a combination of a motor and a speed reducer, a hydraulic pump, etc. Optionally, in this embodiment, as Figure 111 shown, the second driving member 3061 is a motor. The first gear 30621 is connected to the output shaft of the second driving member 3061. The second gear 30622 is installed at one end of the transmission shaft 30631, and the second gear 30622 meshes with the first gear 30621. The transmission shaft 30631 extends along the width direction of the second connecting member 302 and at least partially extends into the inside of the sliding cavity 3051. The third gear 30632 is installed on the transmission shaft 30631 and is arranged inside the sliding cavity 3051, and the third gear 30632 is coaxially arranged with the second gear 30622.

[0375] Please refer to Figure 113 and Figure 116, the rack 30633 is installed on a side wall of the second connecting member 302 facing the bottom wall of the sliding cavity 3051, and the long direction of the rack 30633 is consistent with the length direction of the second connecting member 302. Along the height direction of the cleaning assembly 100, the rack 30633 meshes with the lower third gear 30632. The rack 30633 can be integrally formed and connected with the second connecting member 302, or the rack 30633 can be a separate part and is fixedly connected to the second connecting member 302 through fasteners such as bolts. Optionally, in this embodiment, please refer to Figure 116 , the rack 30633 is integrally formed on the second connecting member 302. Such a setting can save the assembly process of the rack 30633 on the second connecting member 302, which is beneficial to improving the assembly efficiency of the cleaning assembly 100.

[0376] The second driving member 3061 operates to drive the first gear 30621 to rotate. The first gear 30621 drives the second gear 30622 to rotate through meshing transmission. The second gear 30622 drives the transmission shaft 30631 to rotate. The rotation of the transmission shaft 30631 drives the third gear 30632 to rotate. The third gear 30632 meshes with the rack 30633, thereby driving the rack 30633 to move horizontally along its own length direction. Through the horizontal movement of the rack 30633, the sliding of the second connecting member 302 relative to the first connecting member 301 is realized.

[0377] It should be noted that in other embodiments, the rack 30633 can also be installed on a side wall of the second connecting member 302 facing away from the cleaning mechanism 303, and the third gear 30632 is arranged above the rack 30633 and meshes with the rack 30633. With such a setting, the horizontal movement of the rack can also be realized when the second driving member 3061 operates, and further the sliding of the second connecting member 302 relative to the first connecting member 301 can be realized.

[0378] The second driving member 3061 is used to provide rotational power, and the power transmission and conversion are realized through the cooperation of the gear transmission assembly 3062 and the gear-rack transmission assembly 3063. This transmission method has a relatively stable operation process, which is beneficial to improving the smoothness of the sliding process of the second connecting member 302. At the same time, due to the high transmission efficiency and transmission accuracy of the gear-rack transmission, it is beneficial to reduce the power loss during the transmission process and improve the sliding speed of the second connecting member 302 and the control accuracy of the operating position.

[0379] Under the condition of meeting the transmission requirements of the driving assembly 306, the gear transmission assembly 3062 in the above embodiment can be various gear structures such as two meshing spur gears, helical gears, bevel gears, etc. Optionally, in this embodiment, please refer to Figure 111, the gear transmission assembly 3062 includes two bevel gears, that is, both the first gear 30621 and the second gear 30622 are of bevel gear structure. Specifically, please refer to Figure 109 and Figure 111 , a receiving cavity 3012 is provided on one side of the first connecting member 301 in the width direction of the sliding cavity 3051, and the receiving cavity 3012 communicates with the sliding cavity 3051. The second driving member 3061 is disposed in the receiving cavity 3012. Please refer to Figure 94 , a shield 309 may be provided at the opening position of the receiving cavity 3012. The shield 309 is detachably connected to the first connecting member 301. The shield 309 can protect the second driving member 3061 in the receiving cavity 3012 to reduce the probability of bump damage to the second driving member 3061 during use. As Figure 111 shown, the second driving member 3061 is installed along the length direction of the first connecting member 301 so that the output shaft of the second driving member 3061 is perpendicular to the transmission shaft 30631, realizing the meshing between the first gear 30621 and the second gear 30622.

[0380] By setting the first gear 30621 and the second gear 30622 as bevel gear structures, the output shaft of the second driving member 3061 can be perpendicular to the transmission shaft 30631. This structural setting makes it more convenient to set the second driving member 3061 outside the sliding cavity 3051, reducing the probability of interference between the installation position of the second driving member 3061 and the sliding cavity 3051. At the same time, it is also beneficial to reduce the width dimension of the first connecting member 301 and improve the compactness of the structural design.

[0381] To facilitate the installation of the transmission shaft 30631 on the first connecting member 301, optionally, in an embodiment of the present invention, please refer to Figure 109 and Figure 111 , one side of the first connecting member 301 is provided with a mounting shaft hole 3013, and the other side is provided with a clamping interface 3014. One end of the transmission shaft 30631 is rotatably installed in the mounting shaft hole 3013, and the other end of the transmission shaft 30631 is clamped and connected to the clamping interface 3014. Along the width direction of the first connecting member 301, the mounting shaft hole 3013 may be provided on the side of the first connecting member 301 away from the second driving member 3061, or may be provided on the side of the first connecting member 301 close to the second driving member 3061. Optionally, in this embodiment, along the width direction of the first connecting member 301, the mounting shaft hole 3013 is provided on the side of the first connecting member 301 away from the second driving member 3061. Specifically, it is provided on the wall of the sliding cavity 3051 away from the second driving member 3061. The clamping interface 3014 is provided on the side of the first connecting member 301 close to the second driving member 3061, that is, on the wall of the receiving cavity 3012 away from the sliding cavity 3051.

[0382] The transmission shaft 30631 and the mounting shaft hole 3013 can be rotationally connected through shaft hole fitting, or can be rotationally connected through a bearing. Specifically, in this embodiment, please refer to Figure 111 , an eighth bearing 307 is provided in the mounting shaft hole 3013, and one end of the transmission shaft 30631 away from the second driving member 3061 is connected to the eighth bearing 307, thereby realizing the rotational connection between the transmission shaft 30631 and the mounting shaft hole 3013.

[0383] The card interface 3014 can be a U-shaped card slot, a semi-cylindrical card slot and other structures that match the shaft diameter of the transmission shaft 30631. In order to facilitate the engagement between the transmission shaft 30631 and the card interface 3014 and reduce the opening depth of the card interface 3014, optionally, in this embodiment, as Figure 109 and Figure 111 shown, the card interface 3014 is a semi-cylindrical card slot structure with an upward opening.

[0384] Please refer to Figure 154 , a card engaging port 3091 corresponding to the card interface 3014 is provided on the shield 309. After the shield 309 is installed above the accommodating cavity 3012, the card engaging port 3091 is clamped above the transmission shaft 30631 and cooperates with the card interface 3091 to restrict the installation position of the transmission shaft 30631 at the card interface 3014 in the radial direction and improve the transmission accuracy of the transmission shaft 30631.

[0385] Since one end of the transmission shaft 30631 is connected by clamping through the card interface 3014 and the other end is rotationally connected to the mounting shaft hole 3013, during assembly, one end of the transmission shaft 30631 can be first inserted into the card interface 3014, and by pushing the transmission shaft 30631 in the axial direction, the other end of the transmission shaft 30631 can be inserted into the mounting shaft hole 3013 to realize the connection with the mounting shaft hole 3013. With this structure, during the installation process, the gear installed on the transmission shaft 30631 does not need to be removed, so the gear can be installed on the transmission shaft 30631 in advance to improve the installation efficiency of the driving component 306. At the same time, the clamping structure can also facilitate the disassembly and assembly between the transmission shaft 30631 and the first connecting member 301, thereby facilitating disassembly and assembly.

[0386] In order to further simplify the assembly process of the driving component 306 and improve the assembly efficiency, optionally, in an embodiment of the present invention, please refer to Figure 111 and Figure 117, the second gear 30622 and the third gear 30632 are of an integral structure. The second gear 30622 and the third gear 30632 can be formed into an integral structure by casting, or can be formed into an integral structure by welding. By setting the second gear 30622 and the third gear 30632 as an integrally formed part, the number of components and assembly steps in the assembly process can be reduced, the assembly process can be simplified, and thus the overall assembly efficiency of the drive assembly 306 can be improved.

[0387] Optionally, in an embodiment of the present invention, please refer to Figure 100 、 Figure 101 and Figure 109 , a first in-place detection component 308 is provided between the first connecting member 301 and the second connecting member 302. The first in-place detection component 308 is used to detect whether the second connecting member 302 is in the first sliding position or the second sliding position. As Figure 98 shown, when the second connecting member 302 is in the first sliding position, the cleaning mechanism 303 is in the raised position, that is, the cleaning member 110 is disengaged from the ground. As Figure 100 shown, when the second connecting member 302 is in the second sliding position, the cleaning mechanism 303 is in the mopping position, that is, the cleaning member 110 is in contact with the ground to perform normal cleaning operations. The first in-place detection component 308 is electrically connected to the second driving member 3061. The first in-place detection component 308 includes a first detection switch 3081 and a first stopper 3082. One of the first detection switch 3081 and the first stopper 3082 is provided on the first connecting member 301, and the other is provided on the second connecting member 302. Optionally, in this embodiment, the first stopper 3082 is provided on the second connecting member 302, and the first detection switch 3081 is provided on the first connecting member 301. Since the first connecting member 301 is a fixed member, such a setting can facilitate the wiring of the first detection switch 3081. The first detection switch 3081 can be any structure that can meet the in-place detection requirements, such as a mechanical in-place detection switch, a photoelectric in-place detection switch, a Hall sensor detection switch, etc. In this embodiment, the first detection switch 3081 is an optocoupler detection switch. Since the optocoupler detection switch has many advantages such as strong anti-interference ability, fast response speed, and high reliability, better in-place detection accuracy and detection stability can be obtained.

[0388] The number of settings of the first detection switch 3081 and the first stopper 3082 is not limited. In this embodiment, please refer to Figure 100 、 Figure 101 、 Figure 102 and Figure 109, a first detection switch 3081 is provided on the first connecting member 301. Two first stoppers 3082 are provided on the second connecting member 302, and the two first stoppers 3082 are arranged at intervals along the length direction of the second connecting member 302. For the convenience of description, the two first stoppers 3082 are respectively marked as stopper one 30821 and stopper two 30822. As Figure 98 shown, when the first connecting member 301 slides relative to the second connecting member 302, when the first connecting member 301 is at one end of the sliding direction, the stopper one 30821 triggers the first detection switch 3081 to generate a first in-place electrical signal, and the first in-place electrical signal corresponds to the first sliding position of the second connecting member 302. As Figure 100 shown, when the first connecting member 301 is at the other end of the sliding direction, the stopper two 30822 triggers the first detection switch 3081 to generate a second in-place electrical signal, and the second in-place electrical signal corresponds to the second sliding position of the second connecting member 302. The first in-place electrical signal and the second in-place electrical signal are electrically connected to the second driving member 3061 through the control system on the cleaning device 1000. The second driving member 3061 can control the first sliding position and the second sliding position of the second connecting member 302 according to the first in-place electrical signal and the second in-place electrical signal, so as to realize the automatic switching of the cleaning mechanism 303 between the ascending position and the mopping position.

[0389] In other embodiments, it may also be that two first detection switches 3081 are provided and one first stopper 3082 is provided. The first detection switches 3081 are arranged at intervals along the length direction of the first connecting member 301. When the first connecting member 301 is at one end of the sliding direction, the first stopper 3082 triggers one of the first detection switches 3081 to generate a first in-place electrical signal. When the first connecting member 301 is at the other end of the sliding direction, the first stopper 3082 triggers the other first detection switch 3081 to generate a second in-place electrical signal.

[0390] By providing the first in-place detection assembly 308, the first in-place detection assembly 308 can automatically trigger and generate an in-place electrical signal, reducing manual intervention, and thus improving the timeliness and accuracy of the control of the sliding process of the first connecting member 301. At the same time, since the first in-place detection assembly 308 can accurately detect the position of the second connecting member 302, it can ensure that it can accurately reach the first sliding position and the second sliding position during the sliding process.

[0391] In the prior art, the cleaning member 110 on the cleaning device 1000 is usually fixedly arranged relative to the position of the fuselage 200 of the cleaning device 1000, and due to the limitation of the fuselage 200 of the cleaning device 1000, there are certain area limitations when the cleaning member 110 performs cleaning work. For example, the cleaning member 110 cannot clean the corners of the surface to be cleaned, affecting the cleaning effect.

[0392] To solve the above problems, please refer to Figures 118 to 120 , in some embodiments of the present invention, a cleaning assembly 100 is further provided. The cleaning assembly 100 is provided with a translation mechanism 400, and the translation mechanism 400 can drive the cleaning mechanism 303 to move horizontally relative to the fuselage 200, so that the cleaning mechanism 303 has a retracted position or an extended position, thereby improving the cleaning effect of the cleaning device 1000.

[0393] Please refer to Figures 118 to 120 , the cleaning assembly 100 includes a first connecting member 301, a second connecting member 302 and a cleaning mechanism 303.

[0394] The first connecting member 301 is detachably connected to the bottom of the fuselage 200. The detachable connection method can refer to the relevant structure introduction in the foregoing embodiments, and will not be elaborated herein.

[0395] In order to improve the sliding accuracy of the second connecting member 302 relative to the first connecting member 301 and reduce the probability of lateral deviation during sliding, optionally, in an embodiment of the present invention, please refer to Figure 101 , Figure 105 , Figure 109 and Figure 110 , a second guiding assembly 305 for guiding the second connecting member 302 to slide along the first connecting member 301 is provided between the first connecting member 301 and the second connecting member 302. The specific structure of the second guiding assembly 305 can refer to the relevant description in the foregoing embodiments, and will not be described in detail herein.

[0396] Please refer to Figure 96 and Figure 119 , the cleaning mechanism 303 is movably installed on the first connecting member 301, and the cleaning mechanism 303 has an extended position (as shown in Figure 119 ) and a retracted position (as shown in Figure 96 ) relative to the first connecting member 301. The specific structure of the cleaning mechanism 303 can refer to the relevant description of the cleaning mechanism 303 in the foregoing embodiments, and will not be repeated herein. As shown in Figure 155 , when the cleaning mechanism 303 is in the extended position, at least part of the edge of the cleaning member 110 is located outside the projection area of the widest edge of the fuselage 200. As shown in Figure 156 , when the cleaning mechanism 303 is in the retracted position, the edge of the cleaning member 110 is located inside the projection area of the widest edge of the fuselage 200.

[0397] Please refer to Figures 118 to 120, a translation mechanism 400 is provided between the cleaning mechanism 303 and the second connecting member 302. During the sliding of the second connecting member 302 relative to the first connecting member 301, the translation mechanism 400 drives the cleaning mechanism 303 to move horizontally, so that the cleaning mechanism 303 is in the expanded position or the retracted position. For the convenience of description, when the cleaning mechanism 303 is in the retracted position, the sliding position of the second connecting member 302 relative to the first connecting member 301 is defined as the third sliding position (as shown in Figure 96 ), and when the cleaning mechanism 303 is in the expanded position, the sliding position of the second connecting member 302 relative to the first connecting member 301 is defined as the fourth sliding position (as shown in Figure 119 ).

[0398] Exemplarily, when the cleaning assembly 100 needs to clean the corners of the ground, the translation mechanism 400 drives the cleaning mechanism 303 to move from the retracted position to the expanded position, so that at least part of the edge of the cleaning member 110 is located outside the projection area of the widest edge of the fuselage 200, thereby completing the cleaning of the corners. Another example is that when the cleaning assembly 100 needs to perform normal cleaning operations on the ground (without cleaning the corners), the translation mechanism 400 drives the cleaning mechanism 303 to move from the expanded position to the retracted position, so that the edge of the cleaning member 110 is located within the projection area of the widest edge of the fuselage 200, thereby completing the normal cleaning operation of the ground.

[0399] It should be noted that when the translation mechanism 400 drives the cleaning mechanism 303 to move horizontally, the cleaning mechanism 303 can move horizontally along its own length direction or along the width direction of the cleaning mechanism 303. Optionally, please refer to Figure 118 and Figure 119 , in this embodiment, the cleaning mechanism 303 moves horizontally along its own length direction to realize the switching between the retracted position and the expanded position. In this way, the cleaning mechanism 303 can complete the switching between the retracted position and the expanded position with a smaller horizontal displacement, effectively improving the switching efficiency and the space utilization rate at the bottom of the fuselage 200.

[0400] The translation mechanism 400 can be a chute and slider structure. The chute is arranged on the first connecting member 301, and the extending direction of the chute is the same as the horizontal movement direction of the cleaning mechanism 303. One end of the slider is connected to the cleaning mechanism 303, and the other end of the slider is connected to the second connecting member 302. When the second connecting member 302 slides relative to the first connecting member 301, the slider slides in the chute, thereby driving the cleaning mechanism 303 to move horizontally relative to the first connecting member 301. The translation mechanism 400 can also be a guide rail and slider structure. The guide rail is installed on the first connecting member 301, and the length direction of the guide rail is the same as the horizontal movement direction of the cleaning mechanism 303. Both the cleaning mechanism 303 and the second connecting member 302 are fixed to the slider, and the slider is slidably installed on the guide rail through a guide rail pair. When the second connecting member 302 slides relative to the first connecting member 301, the slider slides along the guide rail, thereby driving the cleaning mechanism 303 to move horizontally relative to the first connecting member 301.

[0401] By providing the translation mechanism 400 in the cleaning assembly 100 of the present invention, when the second connecting member 302 slides relative to the first connecting member 301, the translation mechanism 400 can drive the cleaning mechanism 303 to move horizontally, so that the cleaning mechanism 303 can be switched between the extended position and the retracted position. With this arrangement, when the cleaning is performing normal cleaning operations (without cleaning the corners), the cleaning member 110 only needs to be in the retracted position to clean the surface to be cleaned. This can reduce the area of the cleaning member 110 protruding outside the body of the machine, thereby reducing the probability of accidental damage to the cleaning mechanism 303 caused by external force collision and friction. Therefore, it is more suitable for operating in complex environments, such as scenarios where frequent movement or cleaning operations in narrow spaces are required. When the cleaning device 1000 needs to clean the corners of the surface to be cleaned, the cleaning member 110 can move from the retracted position to the extended position, thereby achieving effective cleaning of the corner area of the cleaning device 1000, and further improving the cleaning effect of the cleaning device 1000 on the corners.

[0402] Optionally, in an embodiment of the present invention, the range of the outward expansion and inward contraction stroke of the cleaning mechanism 303 is 40-50 mm, that is, the horizontal stroke range of the cleaning mechanism 303 moving from the inward contraction position to the outward expansion position is 40-50 mm. Preferably, the outward expansion and inward contraction stroke of the cleaning mechanism 303 is 46.5 mm. Limiting the outward expansion and inward contraction stroke of the cleaning mechanism 303 within the range of 40-50 mm can ensure that the cleaning assembly 100 can cover the predetermined corner cleaning area when in the outward expansion position, and can also prevent the cleaning assembly 110 from being overly retracted, resulting in insufficient cleaning range, thus facilitating the guarantee of the consistency of the cleaning effect. At the same time, since an excessive stroke may cause overload to the translation mechanism (such as a motor, a cylinder, etc.) and shorten its service life, therefore, limiting the outward expansion and inward contraction stroke of the cleaning mechanism 303 within the range of 40-50 mm can avoid an excessive stroke of the translation mechanism 400, thereby protecting the translation mechanism 400 and extending its service life.

[0403] Optionally, in an embodiment of the present invention, please refer to Figure 155 , when the cleaning mechanism 303 is in the outward expansion position, along the moving direction of the cleaning mechanism 303, the dimension D of the outer edge of the cleaning mechanism 303 exceeding the outer edge of the fuselage 200 is 7-9 mm, for example, it can be 7 mm, 8 mm or 9 mm, etc. Preferably, D is 8.75 mm. The dimension C of the outer edge of the cleaning member 110 mounted on the cleaning mechanism 303 exceeding the outer edge of the fuselage 200 is 2-4 mm, for example, it can be 2 mm, 3 mm or 4 mm, etc. Preferably, C is 3 mm. By limiting the dimension D of the outer edge of the cleaning mechanism 303 exceeding the outer edge of the fuselage 200 between 7-9 mm, this can ensure that the outward expansion position of the cleaning mechanism 303 can cover a larger cleaning range, ensure that the cleaning member 110 can reach farther positions, especially difficult-to-clean areas such as the wall edge and the corner, and at the same time can prevent the translation mechanism 400 from being overloaded due to excessive extension. By limiting the dimension C of the outer edge of the cleaning member 110 exceeding the outer edge of the fuselage 200 between 2-4 mm, this can ensure that the cleaning member 110 can effectively cover the corner area outside the fuselage 200, reduce the area of the cleaning operation blind area, and thus improve the cleaning effect at the corner position.

[0404] Optionally, in an embodiment of the present invention, please refer to Figure 105 , Figure 109 , Figure 118 and Figure 120, the translation mechanism 400 includes a second through groove 3053 and a connection component 320. The second through groove 3053 is provided on the first connection member 301, and the cleaning mechanism 303 is connected to the second connection member 302 through the connection component 320. At least a part of the connection component 320 is slidably connected to the second through groove 3053. The second through groove 3053 extends along the length direction of the cleaning mechanism 303. One second through groove 3053 can be provided, or two or more second through grooves 3053 can be provided. Optionally, in this embodiment, please refer to Figure 109 and Figure 111 , along the width direction of the first connection member 301, two second through grooves 3053 are arranged side by side. A part of the connection component 320 is slidably connected to one of the two second through grooves 3053, and another part of the connection component 320 is slidably connected to the other second through groove 3053. This can improve the smoothness of the translation mechanism 400 driving the second connection member 302 to move. One connection component 320 can be provided, or multiple connection components 320 can be provided. Optionally, please refer to Figure 118 , in this embodiment, along the length direction of the cleaning mechanism 303, two connection components 320 are provided. This can form two lifting points in the length direction of the cleaning mechanism 303, so that the weight of the cleaning mechanism 303 can be effectively dispersed, avoiding tilting or shaking caused by single-point force, and being beneficial to further improving the stability of the translation movement of the cleaning mechanism 303.

[0405] Under the condition of satisfying the connection relationship between the second connection member 302 and the cleaning mechanism 303, in this embodiment, the specific structure of the connection component 320 is not limited. For example, the connection component 320 can be a combined structure of a connection block and a fastener. One end of the connection block is connected to the cleaning mechanism 303. After the other end of the connection block passes through the second through groove 3053, it is fixedly connected to the bottom surface of the second connection member 302 through a fastener (such as a bolt, a screw, etc.). The connection component 320 can also be a combination of a connection block and a clamping structure. One end of the connection block is connected to the cleaning mechanism 303, and the other end of the connection block is engaged with a clamping mechanism provided on the second connection member 302 to realize the connection between the second connection member 302 and the cleaning mechanism 303.

[0406] In this embodiment, through the mutual cooperation of the second through groove 3053 and the connection component 320, when the second connection member 302 slides relative to the first connection member 301, the connection component 320 can drive the cleaning mechanism 303 to move horizontally, so as to realize the switching between the retracted position and the expanded position. This structural design can reduce the complex transmission components in the traditional translation mechanism 400 and simplify the overall mechanical structure. At the same time, due to the small number of components and the simplified structure, it is beneficial to reduce the manufacturing cost of the cleaning device 1000.

[0407] Optionally, in an embodiment of the present invention, please refer to Figures 120 to 123, the connecting component 320 includes a connecting end 3015, a resisting portion 3042, and a clamping groove 321. The resisting portion 3042 is disposed on a side of the second connecting member 302 facing away from the cleaning mechanism 303, and the clamping groove 321 is provided on a side of the second connecting member 302 facing away from the cleaning mechanism 303. The resisting portion 3042 is clamped within the clamping groove 321 and can form a limit in the sliding direction of the second connecting member 302. Please refer to Figure 120 and Figure 123 , one end of the connecting end 3015 is connected to a side of the cleaning mechanism 303 facing the first connecting member 301, and the other end of the connecting end 3015 sequentially passes through the second through groove 3053 and the bottom wall of the second connecting member 302 from bottom to top along the height direction of the cleaning mechanism 303 and then is connected to the resisting portion 3042. The clamping groove 321 is supported below the resisting portion 3042, and the resisting portion 3042 is pressed against the bottom wall of the clamping groove 321 by the gravity of the cleaning mechanism 303.

[0408] For the convenience of description, the specific structure of any one connecting component 320 will be taken as an example for expansion and description. Specifically, please refer to Figures 120 to 122 , at one end of the second connecting member 302 in the length direction, two first through grooves 3023 are provided on the bottom wall of the second connecting member 302. Along the width direction of the second connecting member 302, the two first through grooves 3023 are respectively disposed on both sides of the clamping groove 321. The shape of the first through groove 3023 is not limited as long as it can allow the extending portion 3011 to pass through. Please refer to Figure 120 and Figure 123 , the connecting end 3015 includes two extending portions 3011, and each extending portion 3011 corresponds to a first through groove 3023. One end of the extending portion 3011 is connected to the cleaning mechanism 303, and the other end of the extending portion 3011 is inserted into the first through groove 3023 and at least partially extends to a side of the second connecting member 302 facing away from the cleaning mechanism 303. Both ends of the resisting portion 3042 are respectively connected to the two extending portions 3011, thereby realizing the clamping connection between the resisting portion 3042 and the clamping groove 321, and thus realizing the connection between the second connecting member 302 and the cleaning mechanism 303. By making the resisting portion 3042 abut against and press the bottom wall of the clamping groove 321, the connecting component 320 can form a relatively stable connection relationship with the second connecting member 302 under the action of the gravity of the cleaning mechanism 303. This connection relationship can not only reduce the risk of the cleaning mechanism 303 falling due to mechanical looseness, but also improve the operation reliability of the cleaning device 1000.

[0409] In order to reduce the installation space occupied by the connecting component 320 in the height direction of the cleaning device 1000, optionally, please refer to Figures 120 to 122In one embodiment of the present invention, the second connecting member 302 includes a concave cavity 3021, which is concave toward a side away from the cleaning mechanism 303, and the bottom wall of the concave cavity 3021 is slidably abutted against the bottom wall of the sliding cavity 3051. The clamping groove 321 is disposed in the concave cavity 3021. The second through groove 3053 is disposed in the bottom wall of the concave cavity 3021, and the extension portion 3011 passes through the second through groove 3053 and is at least partially located in the concave cavity 3021.

[0410] The setting of the concave cavity 3021 enables at least part of the extension portion 3011 and the supporting portion 3042 to be accommodated inside the second connecting member 302, thereby reducing the installation space occupied by the connecting assembly 320 in the height direction of the cleaning device 1000, making the structure of the entire cleaning device 1000 more compact and helping to reduce the overall height dimension.

[0411] The forming method of the snap-in groove 321 in the concave cavity 3021 is not limited. For example, two protrusions may be provided on the bottom wall of the concave cavity 3021, and the snap-in groove 321 is formed between the two protrusions and the bottom wall of the concave cavity 3021. Alternatively, a snap-in groove structure may be connected to the bottom wall of the concave cavity 3021. Optionally, in one embodiment of the present invention, please refer to Figures 120 to 122 The concave cavity 3021 is provided with a protruding structure 3022 inside, the protruding structure 3022 connects a side wall of the concave cavity 3021 in the length direction and the bottom wall of the concave cavity 3021, and a clamping groove 321 is formed between the protruding structure 3022, the bottom wall of the concave cavity 3021 and the side wall of the concave cavity 3021. It should be noted that the length direction of the concave cavity 3021 is consistent with the length direction of the second connecting member 302. For details, please refer to Figure 122 , along the length direction of the concave cavity 3021, the wall of the concave cavity 3021 away from the protruding structure 3022 is marked as the first side wall 30211. The protruding structure 3022, the bottom wall of the concave cavity 3021 and the side wall of the concave cavity 3021 are surrounded by the clamping groove 321, which means that the protruding structure 3022, the bottom wall of the concave cavity 3021 and the first side wall 3021 are surrounded by the clamping groove 321. The protruding structure 3022 can be a rectangular protrusion, a wedge-shaped protrusion, a trapezoidal protrusion and other structures, which are not limited in this embodiment.

[0412] Since a protruding structure 3022 is provided inside the concave cavity 3021, and the protruding structure 3022 connects the side wall and the bottom wall of the concave cavity 3021, such a configuration can improve the connection support strength of the side wall of the snap-in groove 321, and reduce the probability of deformation of the snap-in groove 321 during long-term operation, which causes the supporting portion 3042 to shift inside the snap-in groove 321, thereby improving the switching accuracy of the cleaning mechanism 303 between the retracted position and the expanded position.

[0413] Optionally, in one embodiment of the present invention, please refer toFigures 120 to 122 The convex structure 3022 includes an inclined surface 30411. Along the depth direction of the concave cavity 3021, the inclined surface 30411 inclines from the bottom wall of the concave cavity 3021 towards the opening side of the concave cavity 3021. One end of the inclined surface 30411 is connected to the bottom wall of the concave cavity 3021. For the convenience of description, the bottom wall of the concave cavity 3021 connected to the inclined surface 30411 is marked as the first plane 30412, that is, one end of the inclined surface 30411 is connected to the first plane 30412. The other end of the inclined surface 30411 extends towards the opening side of the concave cavity 3021. Along the width direction of the concave cavity 3021, two first through grooves 3023 are respectively arranged on both sides of the inclined surface 30411, and the first through groove 3023 is a long groove structure extending along the length direction of the concave cavity 3021, and the extension part 3011 is slidably installed in the first through groove 3023. When the cleaning mechanism 303 is in the retracted position, under the sliding action of the second connecting member 302, the abutting portion 3042 can slide along the inclined surface 30411 to drive the cleaning mechanism 303 to move up and down relative to the first connecting member 301.

[0414] The abutting portion 3042 can be any structure such as an inclined block, an arc-shaped block, a pin shaft, etc. that can slide along the inclined surface 30411. Optionally, in this embodiment, please refer to Figure 120 In the figure, the abutting portion 3042 is a pin shaft, and pin shaft mounting holes 30111 are provided on both extension parts 3011, and both ends of the pin shaft are respectively installed in the pin shaft mounting holes 30111 on the corresponding side. This can effectively reduce the friction generated between the abutting portion 3042 and the inclined surface 30411 during mutual movement, so as to facilitate the up and down sliding of the abutting portion 3042 along the inclined surface 30411. It should be noted that the pin shaft and the pin shaft mounting hole 30111 can be rotatably connected or fixedly connected, and this embodiment is not limited thereto.

[0415] For the convenience of description, in this embodiment, the sliding direction of the second connecting member 302 when the cleaning mechanism 303 moves from the retracted position to the expanded position is defined as the first direction, as shown by the arrow direction of S1 in Figure 96 the figure. The sliding direction of the second connecting member 302 when the cleaning mechanism 303 moves from the expanded position to the retracted position is defined as the second direction, as shown by the arrow direction of S2 in Figure 119 the figure.

[0416] Please refer to Figures 118 to 120 In the figure, during the process of the cleaning mechanism 303 moving from the expanded position to the retracted position, that is, when the second connecting member 302 slides along the second direction, first, as shown in Figure 120 and Figure 126As shown, in the initial state, one end of the extension portion 3011 abuts against the end of the second through groove 3053 away from the driving structure 160, and the abutting portion 3042 is engaged with the clamping groove 321. When the second connecting member 302 slides in the second direction, it drives the cleaning mechanism 303 to move horizontally synchronously until the cleaning mechanism 303 moves from the Figure 118 outward expansion position shown to the Figure 124 retracted position shown. At the Figure 124 retracted position shown, at this time, one end of the second through groove 3053 abuts against one side of the extension portion 3011 in the second direction, as shown in Figure 127 to limit the further horizontal movement of the cleaning mechanism 303 in the second direction. In this state, the cleaning mechanism 303 is in contact with the surface to be cleaned and is in the mopping position.

[0417] Please refer to Figure 96 and Figure 124 . After the cleaning mechanism 303 retracts in place and the second connecting member 302 continues to slide in the second direction, under the action of the second through groove 3053, the extension portion 3011 no longer moves relative to the first connecting member 301. Please refer to Figure 120 . At this time, the pin shaft starts to slide upward along the inclined surface 30411, and the extension portion 3011 slides in the first through groove 3023 relative to the second connecting member 302, thereby driving the cleaning mechanism 303 to move upward relative to the first connecting member 301, so that the pin shaft moves from the Figure 120 position shown to the Figure 98 position shown, and then the cleaning mechanism 303 is converted from the Figure 96 mopping position shown to the Figure 95 rising position shown. Please refer to Figure 98 . When the other end of the first through groove 3023 abuts against the other side of the extension portion 3011 in the second direction, it indicates that the cleaning mechanism 303 has risen in place. At this time, the second connecting member 302 stops sliding and the cleaning mechanism 303 stops lifting. At this time, the cleaning mechanism 303 is in the Figure 95 retracted rising position shown.

[0418] When the cleaning mechanism 303 needs to perform a cleaning operation again, that is, when it needs to be switched from the rising position to the mopping position, at this time, slide the second connecting member 302 in the Figure 95 first direction shown. Since there is no abutting effect between the first through groove 3023 and the extension portion 3011 in the first direction, as shown in Figure 98As shown, therefore, when the second connecting member 302 slides, it will not drive the extension portion 3011 to generate horizontal movement in the first direction. At this time, under the action of the gravity of the cleaning mechanism 303, the pin shaft starts to slide downward along the inclined surface 30411, and the extension portion 3011 slides in the opposite direction in the first through groove 3023 relative to the second connecting member 302, thereby driving the cleaning mechanism 303 to move downward relative to the first connecting member 301, realizing the descending action of the cleaning mechanism 303, as Figure 100 shown. At this time, the pin shaft is engaged with the engaging groove 321 again, that is, the pin shaft is in contact with the first plane 30412, and the cleaning mechanism 303 switches to the mopping position again, the second connecting member 302 stops sliding, and the cleaning mechanism 303 stops descending. The cleaning mechanism is in Figure 96 the retracted mopping position shown.

[0419] When the cleaning mechanism needs to expand for corner operations, at this time, when the cleaning mechanism 303 needs to move from the retracted position to the expanded position, that is, the second connecting member 302 needs to move along the first direction from Figure 96 the position to Figure 119 the position shown. First, as Figure 118 and Figure 127 shown, in the initial state, one end of the extension portion 3011 abuts against the end of the second through groove 3053 away from the driving structure 160, and the abutting portion 3042 is engaged with the engaging groove 321. When the second connecting member 302 slides along the first direction, it drives the cleaning mechanism 303 to move horizontally synchronously until the cleaning mechanism 303 moves from Figure 96 and Figure 99 the retracted position shown to Figure 119 and Figure 124 the expanded position shown. At the expanded position shown in Figure 124 , at this time, one end of the second through groove 3053 abuts against one side of the extension portion 3011 along the second direction, as Figure 126 shown, to limit the further horizontal movement of the cleaning mechanism 303 along the first direction. In this state, the cleaning mechanism 303 is in the expanded mopping position.

[0420] By setting the inclined plane 30411, when the cleaning mechanism 303 is in the retracted position, the pin shaft can slide along the inclined plane 30411 to drive the cleaning mechanism 303 to move up and down relative to the first connecting member 301. With this setting, through the sliding of the second connecting member 302, not only can the switching between the expanded position and the retracted position of the cleaning mechanism 303 be realized, but also the up and down movement of the cleaning mechanism 303 relative to the first connecting member 301 can be realized, realizing the switching between the mopping position and the raised position. Furthermore, it can better meet the cleaning operations in various application scenarios. For example, during the cleaning operation, when the body 200 passes over the carpet, the cleaning mechanism 303 can be switched to the raised position to avoid wetting the carpet; or, in scenarios such as obstacle crossing or returning to the base station, the cleaning mechanism 303 can also be switched to the raised position to prevent the cleaning mechanism 303 from being stuck by obstacles and detaching from the body 200.

[0421] Optionally, in an embodiment of the present invention, please refer to Figures 120 to 122 , the convex structure 3022 further includes a second plane 30413, and the second plane 30413 is arranged on the side of the inclined plane 30411 away from the first plane 30412. As Figure 122 shown, along the length direction of the cavity 3021, one end of the second plane 30413 is connected to the side of the inclined plane 30411 away from the first plane 30412, and the other end of the second plane 30413 is connected to the side wall of the cavity 3021 away from the first side wall 30211, and the second plane 30413 and the first plane 30412 are arranged in parallel. As Figure 98 shown, when the cleaning mechanism 303 is in the raised position, the abutting portion 3042 abuts against the second plane 30413. With this setting, when the cleaning mechanism 303 is in the raised position, no additional braking force needs to be set, and the abutting portion 3042 can achieve self-locking between the abutting portion 3042 and the second plane 30413 only through the self-weight of the cleaning mechanism 303. Therefore, not only can the overall structural setting be simplified, but also the stability of the cleaning mechanism 303 in the raised position can be ensured, preventing accidental movement or position change caused by external force or vibration.

[0422] When the second connecting member 302 slides relative to the first connecting member 301, it can be by manually pushing the second connecting member 302 to make the second connecting member 302 slide relative to the first connecting member 301. It can also be by additionally arranging a driving assembly 306 between the first connecting member 301 and the second connecting member 302, and driving the second connecting member 302 to slide relative to the first connecting member 301 through the driving assembly 306. Optionally, in an embodiment of the present invention, please refer to Figure 97 and Figure 99, a driving component 306 is provided between the first connecting member 301 and the second connecting member 302. The fixed end of the driving component 306 is connected to the first connecting member 301, and the driving end of the driving component 306 is connected to the second connecting member 302. The driving component 306 operates to move the second connecting member 302 to slide relative to the first connecting member 301. The driving component 306 can be any linear driving mechanism such as a gear-rack structure, a motor and ball screw structure, a cylinder or a hydraulic cylinder that can realize the sliding of the second connecting member 302 relative to the first connecting member 301.

[0423] By providing the driving component 306, automatic control of the sliding operation of the second connecting member 302 relative to the first connecting member 301 can be realized, and thus the operation efficiency and control accuracy can be improved. At the same time, since the provided driving component 306 can realize the automatic control of the sliding operation of the first connecting member 301, there is no need to reserve manual operation space on the cleaning component 100, and thus the compactness of the internal structure of the cleaning component 100 can be improved.

[0424] It should be noted that the driving component 306 in this embodiment can adopt the structure of the driving component 306 in the above embodiment, and thus also has the beneficial effects of the driving component 306 in the above embodiment. Of course, it can be understood that in this embodiment, other driving components can also be used to drive the sliding of the second connecting member 302, as long as the sliding performance requirements of the second connecting member 302 are met.

[0425] Optionally, in an embodiment of the present invention, please refer to Figure 98 and Figure 100 , a first in-place detection component 308 is provided between the first connecting member 301 and the second connecting member 302. The first in-place detection component 308 is used to detect whether the second connecting member 302 is in the first sliding position or the second sliding position. The first in-place detection component 308 is electrically connected to the second driving member 3061. The specific structure and installation position of the first in-place detection component 308 can refer to the relevant structure description in the above embodiment, and will not be elaborated here.

[0426] On the basis of providing the first in-place detection component 308 between the first connecting member 301 and the second connecting member 302, optionally, in an embodiment of the present invention, please refer to 124 and Figure 125 , a second in-place detection component 310 is further provided between the first connecting member 301 and the second connecting member 302. The second in-place detection component 310 is used to detect whether the second connecting member 302 is in the third sliding position or the fourth sliding position. As Figure 128 and Figure 129 shown, when the second connecting member 302 is in the third sliding position, the cleaning mechanism 303 is in the retracted position. As Figure 130 and Figure 131As shown, when the second connecting member 302 is in the fourth sliding position, the cleaning mechanism 303 is in the outward expansion position. The second in-place detection assembly 310 is electrically connected to the second driving member 3061. As Figure 125 shown, the second in-place detection assembly 310 includes a second detection switch 311 and a second stopper 312. One of the second detection switch 311 and the second stopper 312 is disposed on the first connecting member 301, and the other is disposed on the second connecting member 302. Optionally, in this embodiment, the second stopper 312 is disposed on the second connecting member 302, and the second detection switch 311 is disposed on the first connecting member 301. Since the first connecting member 301 is a fixed member, such an arrangement can facilitate the wiring of the second detection switch 311. The second detection switch 311 can be any structure that can meet the in-place detection requirements, such as a mechanical in-place detection switch, an optoelectronic in-place detection switch, a Hall sensor detection switch, etc. In this embodiment, the second detection switch 311 is an optocoupler detection switch. Since the optocoupler detection switch has many advantages such as strong anti-interference ability, fast response speed, and high reliability, better in-place detection accuracy and detection stability can be obtained.

[0427] The number of the second detection switch 311 and the second stopper 312 is not limited. In this embodiment, please refer to Figure 125 As shown, one second detection switch 311 is disposed on the first connecting member 301. Two second stoppers 312 are disposed on the second connecting member 302, and the two second stoppers 312 are spaced apart along the length direction of the second connecting member 302. For the convenience of description, the two second stoppers 312 are respectively marked as stopper three 3121 and stopper four 3122. As Figure 129 shown, when the second connecting member 302 slides relative to the first connecting member 301, when the second connecting member 302 is at one end of the sliding direction, the stopper three 3121 triggers the second detection switch 311 to generate a third in-place electrical signal, and the third in-place electrical signal corresponds to the third sliding position of the second connecting member 302. When the second connecting member 302 is at the other end of the sliding direction, the stopper four 3122 triggers the second detection switch 311 to generate a fourth in-place electrical signal, and the fourth in-place electrical signal corresponds to the fourth sliding position of the second connecting member 302. The third in-place electrical signal and the fourth in-place electrical signal are electrically connected to the second driving member 3061 through a controller on the cleaning device 1000. The second driving member 3061 can control the third sliding position and the fourth sliding position of the second connecting member 302 according to the third in-place electrical signal and the fourth in-place electrical signal, so as to realize the automatic switching of the cleaning mechanism between the retracted position and the outward expansion position.

[0428] In other embodiments, two second detection switches 311 may be provided and one second stopper 312 may be provided. The second detection switches 311 are arranged at intervals along the length direction of the first connecting member 301. When the first connecting member 301 is at one end in the sliding direction, the second stopper 312 triggers one of the second detection switches 311 to generate a third in-place electrical signal. When the first connecting member 301 is at the other end in the sliding direction, the second stopper 312 triggers the other second detection switch 311 to generate a fourth in-place electrical signal.

[0429] By providing the second in-place detection assembly 310, the second in-place detection assembly 310 can automatically trigger and generate an in-place electrical signal, reducing manual intervention, and thus improving the timeliness and accuracy of the control of the sliding process of the second connecting member 302. At the same time, since the second in-place detection assembly 310 can accurately detect whether the second connecting member 302 is in the third sliding position or the fourth sliding position, the repeated in-place accuracy can be ensured when the cleaning mechanism 303 switches between the retracted position and the extended position.

[0430] It should be noted that, please refer to Figure 132 , when the cleaning mechanism 303 is in the retracted and raised position, at this time, the first stopper 30821 triggers the first detection switch 3081 to generate a first in-place electrical signal, and the second detection switch remains in the non-triggered state. Please refer to Figure 129 , when the cleaning mechanism 303 is in the retracted mopping position, at this time, the second stopper 30822 triggers the first detection switch 3081 to generate a second in-place electrical signal. At the same time, the third stopper 3121 triggers the second detection switch 311 to generate a third in-place electrical signal. Please refer to Figure 131 , when the cleaning mechanism 303 is in the extended position, at this time, the first detection switch remains in the non-triggered state, and the fourth stopper 3122 triggers the second detection switch 311 to generate a fourth in-place electrical signal.

[0431] Please refer to Figure 133 and Figure 134 , in an embodiment of the present invention, a fresh water tank 500 and a sewage tank 600 are further provided on the body 200 of the cleaning device 1000. The fresh water tank 500 is used to supply fresh water to the cleaning member 110 so that the cleaning member 110 can maintain a wet state during the cleaning operation, realizing wet mopping of the surface to be cleaned and improving the cleaning effect. The sewage tank 600 is used to store sewage, and the sewage generated by the cleaning member 110 after the mopping operation is pumped into the sewage tank 600.

[0432] Please refer to Figure 135 and Figure 136, a clear water outlet 501, a sewage suction port 502 and a sewage collection chamber 503 are provided on the housing 180 of the cleaning assembly 100. The sewage suction port 502 communicates with the sewage collection chamber 503. The sewage in the sewage collection chamber 503 is discharged through the sewage suction port 502. A plurality of clear water outlets 501 are provided, and the plurality of clear water outlets 501 are arranged at intervals along the length direction of the housing 180. Such an arrangement can improve the uniformity of the water replenishment effect of the cleaning member 110.

[0433] Please refer to Figure 135 and Figure 137 , an external portion of the housing 180 is further provided with a clear water delivery pipe 504 and a sewage suction port outlet 5021. The sewage suction port outlet 5021 communicates with the sewage suction port 502. The clear water delivery pipe 504 communicates the clear water tank 500 and the clear water outlet 501. The clear water tank 500 delivers clear water to the clear water outlet 501 through the clear water delivery pipe 504, and the clear water is sprayed onto the surface of the cleaning member 110 through the clear water outlet 501, so that the cleaning member 110 is wetted with clear water.

[0434] Optionally, please refer to Figure 137 , in an embodiment of the present invention, at least a part of the clear water delivery pipe 504 is a heat-conducting pipe section 5041, the first driving member 161 is a motor, the heat-conducting pipe section 5041 is wound around the first driving member 161, and heat conduction can be performed between the heat-conducting pipe section 5041 and the first driving member 161. With such an arrangement, the heat generated during the operation of the first driving member 161 can be conducted to the heat-conducting pipe section 5041 to heat the clear water in the clear water delivery pipe 504, thereby increasing the temperature of the clear water replenished on the cleaning member 110, and further improving the cleaning effect of the cleaning member 110. At the same time, the heat generated during the operation of the first driving member 161 can also be taken away by the continuous flow of the clear water in the clear water delivery pipe 504, and further play a role in cooling the first driving member 161.

[0435] Optionally, in an embodiment, please refer to Figure 137 , the clear water delivery pipe 504 further includes a transition pipe section 5042. A clear water inlet 505 is further provided on a side of the housing 180 facing away from the cleaning member 110. The clear water inlet 505 is provided close to one side of the first driving member 161 and communicates with the clear water outlet 501 inside the receiving chamber 190. One end of the transition pipe section 5042 communicates with the water outlet of the heat-conducting pipe section 5041, and the other end communicates with the clear water inlet 505. By providing the transition pipe section 5042, the connection between the clear water delivery pipe 504 and the clear water inlet 505 can be facilitated. At the same time, since the clear water inlet 505 is provided close to one side of the first driving member 161, the probability of interference between the second connecting member 302 and the clear water delivery pipe 504 when the second connecting member 302 moves relative to the first connecting member 301 can be reduced, thereby improving the stability and reliability of the operation of the cleaning assembly 100.

[0436] Please refer to Figure 135 and Figure 136 During the rotation of the cleaning member 110, it first passes through the clean water outlet 501 for clean water replenishment, and then passes through the sewage collection chamber 503 for sewage collection. Specifically, in this embodiment, the cleaning assembly 100 further includes a water scraping structure 710. The water scraping structure 710 includes a first water scraping member 701 and a second water scraping member 702. The first water scraping member 701 and the second water scraping member 702 are spaced apart in the rotation direction of the cleaning member 110 and both extend along the length direction of the cleaning member 110. The first water scraping member 701, the second water scraping member 702 and the inner wall of the housing 180 enclose to form the above-mentioned sewage collection chamber 503. During the cleaning operation of the cleaning member 110, the cleaning member 110 first passes through the first water scraping member 701, then passes through the second water scraping member 702, and the sewage on the cleaning member 110 is scraped into the sewage collection chamber 503 under the squeezing action of the first water scraping member 701 and the second water scraping member 702. Please refer to Figure 134 、 Figure 135 and Figure 137 The sewage outlet 5021 of the sewage extraction port is connected to the sewage tank 600 through a pipeline, and the sewage in the sewage collection chamber 503 is pumped into the sewage tank 600 through the sewage extraction port 502, thereby realizing the collection of the sewage on the cleaning member 110.

[0437] It should be noted that after the cleaning member 110 is scraped by the first water scraping member 701 and the second water scraping member 702, the surface of the cleaning member 110 presents a flat state under the squeezing action, which will affect the cleaning effect of the cleaning member 110. Based on this, please refer to Figure 135 Along the traveling direction of the cleaning device 1000, the fluffing roller 170 is located at the rear end of the water scraping structure 710, that is, the fluffing roller 170 is located at the rear end of the sewage collection chamber 503. It can be understood that when the water scraping structure 710 scrapes the sewage on the cleaning member 110 and presents a flat state, the fluffing roller 170 acts on the cleaning member 110 and turns up the fluff on the surface of the cleaning member 110, so that the cleaning member 110 presents a fluffy state again. This process can reduce the decline in the cleaning effect caused by the water scraping structure 710 flattening the cleaning member 110.

[0438] In order to further improve the water scraping effect of the water scraping structure 710, optionally, in an embodiment of the present invention, please refer to Figure 135 and Figure 136, the first wiper 701 includes a plurality of first comb teeth 7011 arranged at intervals. One end of the first comb tooth 7011 is connected to the inner wall of the housing 180, and the other end of the first comb tooth 7011 extends toward the cleaning member 110. The second wiper 702 is in the form of a squeegee strip. One end of the second wiper 702 is connected to the inner wall of the housing 180, and the other end extends toward one side of the cleaning member 110. With such an arrangement, on the one hand, the plurality of first comb teeth 7011 can block large particles on the cleaning member 110 from entering the sewage collection chamber 503, greatly reducing the probability of the large particles blocking the sewage extraction port 502. On the other hand, it can also reduce the contact area between the first wiper 701 and the cleaning member 110, which is beneficial to reducing the friction and wear generated during the rotation of the cleaning member 110 and extending the service life of the cleaning member 110. At the same time, since the second wiper 702 is in the form of a squeegee strip, a relatively tight extrusion contact surface can be formed with the cleaning member 110, which is conducive to preventing sewage from flowing out of the sewage collection chamber 503 and polluting the surface to be cleaned.

[0439] Optionally, in another embodiment, please refer to Figure 135 and Figure 136 , a comb member 720 is further provided on the inner wall of the housing 180, and the comb member 720 is in interference contact with the cleaning member 110. Along the traveling direction of the cleaning device 1000, the comb member 720 is located at the front end of the first wiper 701. When the cleaning member 110 performs a cleaning operation, the cleaning member 110 sequentially passes through the comb member 720, the first wiper 701, and the second wiper 702. The comb member 720 extends along the length direction of the cleaning member 110 and includes a plurality of second comb teeth 721. A gap is formed between adjacent second comb teeth 721, and the comb member 720 can block large-sized particles from entering the interior of the housing 180, thereby reducing the damage to the accommodation chamber caused by large-sized particles.

[0440] Please refer to Figure 133 and Figure 134 , the clean water tank 500 is arranged at the rear edge position of the fuselage 200, which facilitates the base station to replenish water to the clean water tank 500. For the convenience of pumping and treating the sewage in the sewage tank 600, the sewage tank 600 is also usually arranged at the rear edge position of the fuselage 200. In order to save the installation space occupied by the sewage tank 600 and the clean water tank 500 on the fuselage 200, optionally, in this embodiment, please refer to Figure 138 and Figure 139, the water tank 500 includes an installation cavity 506, and the opening of the installation cavity 506 faces the circumferential outer side of the fuselage 200. The shape and size of the installation cavity 506 match the shape and size of the sewage tank 600, and the sewage tank 600 is installed in the installation cavity 506. This can not only realize the integrated setting of the sewage tank 600 and the water tank 500, facilitate the disassembly and assembly operations of the water tank 500 and the sewage tank 600 on the fuselage 200, but also reduce the installation area occupied by the water tank 500 and the sewage tank 600 in the horizontal direction of the fuselage 200, thereby optimizing the spatial layout of the fuselage 200 and improving the compactness of the device.

[0441] To improve the installation stability of the water tank 500 on the fuselage 200, optionally, refer to Figure 133 and Figure 134 , in an embodiment, a water tank installation cavity 270 is provided at the rear edge position of the fuselage 200, and the water tank 500 is accommodated in the water tank installation cavity 270. The two side walls of the water tank 500 are fixedly connected to the wall of the water tank installation cavity 270 by bolts. Refer to Figure 134 and Figure 138 , a support plate 507 is further provided at the bottom of the water tank 500. One end of the support plate 507 is fixedly connected to the fuselage 200, and the other end of the support plate 507 supports the bottom of the water tank 500 and is fixedly connected to the bottom wall of the water tank 500. With this setting, connection support points can be formed on both the side wall and the bottom wall of the water tank 500, thereby improving the connection strength between the water tank 500 and the fuselage 200. At the same time, since the sewage tank 600 is provided in the installation cavity 506, the setting of the support plate 507 can also specifically enhance the support strength at the installation position of the sewage tank 600, further improving the installation stability of the sewage tank 600 and the water tank 500 on the fuselage 200.

[0442] Optionally, in an embodiment, the water tank 500 is provided with a first water level detection component (not shown in the figure), and the sewage tank 600 is provided with a second water level detection component (not shown in the figure). The first water level detection component can detect the water level in the water tank 500 in real time to replenish water into the water tank 500 in time to ensure the wetting degree of the cleaning member 110. The second water level detection component can detect the water level in the sewage tank 600 in real time to discharge the sewage in the sewage tank 600 in time to avoid sewage overflow and polluting the ground. The structures of the first water level detection component and the second water level detection component can be the same or different. Optionally, in this embodiment...
