[0187] Please refer to Figures 1 to 88 The present application provides a cleaning assembly 100 and a cleaning device 1000, the cleaning assembly 100 can realize the quick switching of the cleaning piece 110 between the tension state and the relaxation state through the cooperative design of the support assembly 120, the pulling piece 130 and the outer support assembly 140, so that the replacement efficiency of the cleaning piece 110 can be improved, and the cleaning efficiency of the cleaning device 1000 can be improved.

[0188] The cleaning device 1000 provided by the embodiments of the present application can be a self-moving cleaning robot, or a handheld floor washing machine. The self-moving cleaning robot can be a floor mopping robot, or a sweeping and mopping integrated robot.

[0189] In the following embodiments, the cleaning device 1000 is taken as a self-moving cleaning robot to introduce some parts, but those skilled in the art can understand that other robots including the cleaning assembly 100 of the present application can also have the beneficial effects brought by the cleaning assembly 100 of the present application.

[0190] Please refer to Figure 1 , the cleaning device 1000 has a body 200, the inside of the body 200 can accommodate various parts of the cleaning device 1000. The shape of the body 200 can be any shape, such as a cylindrical, oval or D-shaped, and the like.

[0191] The cleaning device 1000 also includes a walking system conventionally provided on the existing cleaning device 1000, for driving the body 200 to move by itself to achieve the walking function of self-moving on the surface to be cleaned. The walking system at least includes a driver and a drive wheel 240, which rotates under the action of the driver. The drive wheel 240 can generally be two, and the two drive wheels 240 are symmetrically arranged at the bottom of the body 200. The specific structure of the walking system and the connection structure between the walking system and the body 200 can be described with reference to the related structure in the existing cleaning device 1000, which will not be described here.

[0192] In order 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 mode can be a clamping detachable connection, a bolt detachable connection, etc. The cleaning assembly 100 can be configured as dry mopping or wet mopping. Alternatively, in this embodiment, the cleaning assembly 100 is configured as wet mopping.

[0193] Alternatively, in an embodiment, please refer to Figures 1 to 3 The cleaning device 1000 can also include a side brush 210 and a roller brush 220, which are arranged at the bottom of the body 200. In the direction of the arrow W1 shown in Figure 2 , the side brush 210 and the roller brush 220 are located in front of the cleaning assembly 100. Among them, the side brush 210 can be arranged at the edge of the body 200, and the side brush 210 can be rotated by a rotating mechanism, which can be a motor, a combination of a motor and a speed reducer, etc. When the side brush 210 rotates, it can gather the garbage at the edge of the body 200 to the inside of the body 200, thereby increasing the cleaning range of the cleaning device 1000. The side brush 210 can be a rubber strip or a brush, etc., as long as it can sweep the ground, which is not limited here. The roller brush 220 is rotatably arranged in the roller brush cavity at the bottom of the body 200, and the roller brush 220 can sweep the garbage on the ground during rolling. The number of roller brushes 220 can be set according to specific requirements, which is not limited in this embodiment.

[0194] The edge brush 210 and the roller brush 220 are arranged in front of the cleaning assembly 100 in the advancing direction of the machine body 200, which facilitates the dry sweeping and wet mopping of the cleaning device 1000 and the layout of the internal space of the machine body 200.

[0195] In addition, the cleaning device 1000 can 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 machine body 200, a bumper and a vision sensor located at the front of the machine body 200, an edge-following sensor located on the side wall of the front of the machine body 200, etc. The LDS, the bumper, and the edge-following sensor can measure or sense the distance between the edge of the machine body 200 and the obstacle, and the control system controls the cleaning device 1000 to perform corresponding actions according to the distance. For example, the control system controls the cleaning device 1000 to perform obstacle avoidance, edge cleaning, and return to the base station.

[0196] For the cleaning assembly 100, the cleaning assembly 100 can have multiple ways. Optionally, in the present embodiment, please refer to Figures 3 to 12 , the cleaning assembly 100 includes a cleaning element 110, a support assembly 120, a pulling element 130, and an outer support assembly 140.

[0197] The cleaning element 110 can be made of fiber cloth, sponge, rubber material, etc., and the cleaning element 110 is wound on the support assembly 120. The winding shape of the cleaning element 110 on the support assembly 120 can be planar, annular, etc. For example, please refer to Figure 4 and Figure 7 In the present embodiment, the cleaning element 110 is wound on the outer periphery of the support assembly 120 in a shape similar to a circular track, to form a structure similar to a track-type.

[0198] Please refer to Figure 9 , Figure 10 and Figure 13The support assembly 120 comprises a first support 121 and a second support 122, and the cleaning element 110 is wound on and supported by the first support 121 and the second support 122. The pulling element 130 is arranged between the first support 121 and the second support 122. When the first support 121 and the second support 122 are separated from each other, the pulling element 130 has a pulling force for pulling the first support 121 and the second support 122 to be close to each other. Specifically, when the first support 121 and the second support 122 are separated from each other, the pulling element 130 is stretched, and the pulling force of the pulling element 130 is increased to make the first support 121 and the second support 122 have a restoring pulling force for being close to each other. When the first support 121 and the second support 122 are close to each other, the pulling element 130 also has a pulling force for pulling the first support 121 and the second support 122 to be close to each other. The pulling element 130 can be a tensile spring, an elastic band, a combination of a rope and a pulley structure, or the like, as long as it can generate a pulling force for pulling the first support 121 and the second support 122 to be close to each other.

[0199] In other embodiments, the pulling element 130 can also have a pulling force for pulling the first support 121 and the second support 122 to be close to each other only when the first support 121 and the second support 122 are separated from each other, and the pulling element 130 does not deform and does not generate a pulling force when the first support 121 and the second support 122 are close to each other.

[0200] The pulling element 130 can be one, two or more, as long as it meets the pulling requirement between the first support 121 and the second support 122. Figure 9 and Figure 10 The pulling element 130 is provided with two pulling elements 130, and the two pulling elements 130 are arranged close to the two ends of the length direction of the support assembly 120.

[0201] Please refer to Figure 13 , Figure 14 and Figure 17The 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, it expands the first bracket 121 and the second bracket 122 to both sides. The outer support assembly 140 can be a single integral piece, which is slidably inserted between the first bracket 121 and the second bracket 122, thereby expanding the first bracket 121 and the second bracket 122 to both sides. The outer support assembly 140 can also be multiple parts, with only some parts slidably inserted between the first bracket 121 and the second bracket 122 to achieve relative separation between 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 shape, and the outer support assembly 140 has at least a first position and a second position on the sliding path.

[0202] like Figure 15 As shown, when the external support assembly 140 is in the first position, the external support assembly 140 provides a first gap between the first bracket 121 and the second bracket 122, which causes the cleaning member 110 to tighten. Figure 17 As shown, when the external support assembly 140 is in the second position, the traction force of the pulling member 130 causes the first bracket 121 and the second bracket 122 to have a second gap that allows the cleaning member 110 to relax. The specific size of the first gap and the second gap is not limited, and needs to be determined according to the size of the cleaning member 110 during the actual design and production process.

[0203] By setting the outer support assembly 140 and the pulling piece 130 between the first support 121 and the second support 122, and making the pulling piece 130 have a pulling force that makes the first support 121 and the second support 122 close to each other, and the outer support assembly 140 slides between the first position and the second position. In this way, when the cleaning piece 110 needs to be tightened, the outer support assembly 140 is slid to the first position, and the first distance between the first support 121 and the second support 122 is formed, so as to realize the tightening of the cleaning piece 110. In the tightened state, the cleaning piece 110 can better approach the surface to be cleaned, improving the cleaning effect. When the cleaning piece needs to be switched to a relaxed state, the outer support assembly 140 is slid to the second position, and the first support 121 and the second support 122 are close to each other under the action of the pulling force, and then the second distance between the first support 121 and the second support 122 is formed, so as to realize the relaxation of the cleaning piece 110. In the relaxed state, it is more conducive to the storage and replacement of the cleaning piece 110. It should be noted that the mutual approach here means that the first support 121 and the second support 122 can approach each other, or can have other distances smaller than the first distance, that is, the distance between the first support 121 and the second support 122 is greater than or equal to zero, and smaller than the first distance. The relevant content below is described here. Therefore, the cleaning assembly 100 can realize the quick switching between the tightening and relaxation states of the cleaning piece 110 through the cooperation of the outer support assembly 140 and the pulling piece 130, and then the replacement operation steps of the cleaning assembly 100 can be simplified, and the replacement operation time can be shortened, so as to improve the replacement efficiency of the cleaning assembly 100 and the cleaning efficiency of the cleaning equipment 1000. Moreover, the cleaning assembly 100 of the utility model is in the rigid tightening state through the outer support assembly 140, which has higher stability than the tightening realized by the compression spring and other elastic assemblies, and can prevent the local twisting or misplacement of the cleaning piece 110 caused by the inconstant tightening force.

[0204] In order to improve the sliding accuracy between the first support 121 and the second support 122, and reduce the jamming phenomenon in the sliding process, optionally, please refer to Figure 14 、 Figure 18 and Figure 20In an embodiment of the present application, a first guiding assembly 150 is arranged between the first support 121 and the second support 122, and the first guiding assembly 150 is used to guide the first support 121 and the second support 122 to slide in the direction of the pulling force. The specific structure of the first guiding assembly 150 can be various, for example, a guide rail and a sliding block structure, a sliding groove and a sliding block structure, a guide rod and a guide sleeve structure, and various structures having a guiding function. By arranging the first guiding assembly 150, the first guiding assembly 150 can ensure that the first support 121 and the second support 122 slide in a predetermined direction, reduce the probability of mutual deviation or shaking during sliding, and thus can improve the sliding accuracy between the first support 121 and the second support 122, reduce the jamming phenomenon during sliding, and be beneficial to improving the smoothness of sliding between the first support 121 and the second support 122. At the same time, the first guiding assembly 150 can also provide additional support for the first support 121 and the second support 122, which is beneficial to enhancing the overall rigidity and stability of the support assembly 120.

[0205] Optionally, in an embodiment of the present application, referring to Figure 14 、 Figure 18 and Figure 20 , the first guiding assembly 150 includes a plug-in part 151 and a clamping groove 152, and the plug-in part 151 and the clamping groove 152 are arranged on the opposite sides of the first support 121 and the second support 122, respectively. During the process that the first support 121 and the second support 122 approach each other or separate from each other, the plug-in part 151 can be slidably inserted into the clamping groove 152. In this embodiment, the plug-in part 151 is arranged on the side of the second support 122 facing the first support 121, and the clamping groove 152 is arranged on the side of the first support 121 facing the second support 122.

[0206] In another embodiment, the plug-in part 151 can be arranged on the side of the first support 121 facing the second support 122, and the clamping groove 152 can be arranged on the side of the second support 122 facing the first support 121. In other embodiments, the plug-in part 151 can be partially arranged on the first support 121 and partially arranged on the second support 122. Correspondingly, the clamping groove 152 is partially arranged on the second support 122 to cooperate with the part of the plug-in part 151 arranged on the first support 121, and the clamping groove 152 is partially arranged on the first support 121 to cooperate with the part of the plug-in part 151 arranged on the second support 122.

[0207] The plug-in part 151 can be a long strip block structure arranged integrally along the length direction of the support assembly 120 (as indicated by the X-axis in Figure 15 ), or can be a plurality of convex block structures arranged at intervals along the length direction of the support assembly 120. The clamping groove 152 is matched in shape with the plug-in part 151 for the plug-in part 151 to be inserted.

[0208] It should be noted that, due to the different matching structures of the plug-in part 151 and the card slot 152, when the plug-in part 151 and the card slot 152 are plugged in, the first support 121 and the second support 122 can be limited and guided in the height direction of the support assembly 120 (such as the Z-axis direction in the figure). Figure 16 The first support 121 and the second support 122 can also be limited and guided in the length direction of the support assembly 120, or can be limited and guided in both the height direction and the length direction of the support assembly 120.

[0209] Specifically, in the embodiment, please refer to Figure 15 , Figure 17 , Figure 18 and Figure 20 , the plug-in part 151 is a long strip structure, and the plug-in part 151 extends along the length direction of the second support 122 and covers the entire length direction of the second support 122. Correspondingly, the card slot 152 extends along the length direction of the first support 121 and covers the entire length direction of the first support 121. When the plug-in part 151 and the card slot 152 are matched with each other, the upper and lower two sides of the plug-in part 151 are matched with the upper and lower two sides of the card slot 152 in the height direction of the support assembly 120, so as to form a abutting relationship during plugging, and further form a guiding effect in the height direction of the support assembly 120 between the first support 121 and the second support 122. It should be noted that the "upper and lower two sides" of the card slot 152 or the plug-in part 151 are the two sides in the Z-axis direction. Figure 16

[0210] By setting the plug-in part 151 and the card slot 152, the matching of the plug-in part 151 and the card slot 152 can make the sliding between the first support 121 and the second support 122 more smooth, and play a sliding guiding role. At the same time, due to the simple structure design of the plug-in part 151 and the card slot 152, it is easy to realize, so as to reduce the production cost.

[0211] Please refer to Figure 14 , Figure 18 , Figure 20 and Figure 21 ​In an embodiment of the present application, the first guiding assembly 150 further comprises guiding grooves 153 and guiding rods 154, the guiding grooves 153 and the guiding rods 154 are respectively arranged on the first support 121 and the second support 122, the guiding rods 154 are inserted into the guiding grooves 153, and slide along the guiding grooves 153 in the process that the first support 121 and the second support 122 approach each other or separate from each other. The guiding grooves 153 are long groove structures extending along the sliding direction of the first support 121 and the second support 122. The cooperation of the guiding grooves 153 and the guiding rods 154 defines the maximum distance between the first support 121 and the second support 122, and the maximum distance is greater than or equal to the first distance.

[0212] The number of the guiding grooves 153 and the guiding rods 154 is not limited, and one or more can be arranged. One guiding groove 153 can correspond to one guiding rod 154, and one guiding groove 153 can also correspond to multiple guiding rods 154. Alternatively, please refer to Figure 13 In the embodiment, two guiding grooves 153 and two guiding rods 154 are arranged at intervals along the length direction of the support assembly 120, and one guiding rod 154 is correspondingly inserted into one guiding groove 153.

[0213] Specifically, please refer to Figure 18 , Figure 20 and Figure 21 In the embodiment, the two guiding grooves 153 are arranged on the second support 122 and located on the insertion part 151. The two guiding rods 154 are arranged on the first support 121 and connected with the groove wall of the clamping groove 152. In another embodiment, the two guiding grooves 153 can also be arranged on the first support 121, and the two guiding rods 154 can be arranged on the second support 122. In other embodiments, the two guiding grooves 153 can be respectively arranged on the first support 121 and the second support 122, and the two guiding rods 154 can be respectively arranged on the first support 121 and the second support 122.

[0214] By setting the guide groove 153 and the guide rod 154, the guide rod 154 slides in the guide groove 153, on the one hand, the maximum separation distance (greater than or equal to the first interval) and the minimum approach distance (i.e. the second interval) between the first support 121 and the second support 122 can be limited, ensuring the consistency of the tensioning degree of the support assembly 120 to the cleaning piece 110. At the same time, it can also limit the movement distance of the plug-in part 151 in the clamping groove 152, and then it can ensure that at least part of the plug-in part 151 is always located in the clamping groove 152, that is, when the first support 121 and the second support 122 are at the maximum separation distance, at least part of the plug-in part 151 is always located in the clamping groove 152, which is beneficial to improve the smoothness of the sliding between the first support 121 and the second support 122. On the other hand, the guide groove 153 and the guide rod 154 cooperate with each other to guide the mutual movement of the first support 121 and the second support 122, so as to further improve the guiding effect between the first support 121 and the second support 122 and ensure the sliding accuracy.

[0215] Considering the repeated position accuracy when the first support 121 and the second support 122 approach each other, optionally, referring to Figure 14 and Figure 17 In an embodiment of the present application, the side of the first support 121 towards the second support 122 comprises a first butt joint 1211, and the side of the second support 122 towards the first support 121 comprises a second butt joint 1221. When the first support 121 and the second support 122 approach each other, the first butt joint 1211 and the second butt joint 1221 butt joint with each other and form a butt joint 123, and the butt joint 123 comprises a bending section 1231. The butt joint 123 can be a continuous butt joint structure distributed along the length direction of the support assembly 120, or can be a plurality of intermittent butt joint structures. Optionally, in this embodiment, the butt joint 123 is a continuous butt joint structure 123 distributed along the length direction of the support assembly 120, and the length of the butt joint 123 covers the length of the support assembly 120.

[0216] The bending section 1231 can be various bending structures such as arc bending, V-shaped bending, and wave-shaped bending. One bending section 1231 can be provided on the butt joint 123, or a plurality of bending sections 1231 can be provided. Optionally, referring to Figure 14 In this embodiment, a plurality of bending sections 1231 in the shape of approximate trapezoids are provided on the butt joint 123. This structure is beneficial to guide the butt joint of the first support and the second support, and form a limit between them. Compared with a straight line joint structure, this structure has higher butt joint stability.

[0217] Specifically, in this embodiment, referring to Figure 19 and Figure 20The insertion portion 151 has a boss structure formed on the side opposite to the slot 152. The boss structure includes multiple first protrusions 1511 protruding towards the slot 152 and multiple first recesses 1512 recessed on the side opposite to the slot 152. The slot 152 has multiple second recesses 1522 and multiple second protrusions 1521 correspondingly provided on the wall edge on the side opposite to the insertion portion 151. The second recesses 1522 correspond to and match the first protrusions 1511, and the second protrusions 1521 correspond to and match the first recesses 1512. When the first mating portion 1211 and the second mating portion 1221 are mated together, the first recesses 1512 and the second protrusions 1521 are aligned, and the first protrusions 1511 and the second recesses 1522 are aligned, thereby forming a mating seam 123 with a bent section 1231.

[0218] Because the joint 123 includes a bent section 1231, when the first mating part 1211 and the second mating part 1221 are mated, they can be connected in both the length and width directions of the bracket assembly 120 (e.g., ...). Figure 15 Positioning is achieved simultaneously on the Y-axis (as shown in the middle). This design ensures that the first bracket 121 and the second bracket 122 can accurately align in a predetermined direction, reducing the possibility of misalignment or wobbling during the alignment process. This improves the alignment accuracy when the first bracket 121 and the second bracket 122 approach each other, and ensures the repeatability accuracy of their positions when they are close together.

[0219] Although the tension member 130 can have various structures, considering the manufacturing cost and structural complexity of the tension member 130, optionally, in one embodiment of this utility model, please refer to... Figure 9 and Figure 10 The tensioning element 130 is an elastic element, with its two ends connected to the first support 121 and the second support 122 respectively. The elastic force generated by the elastic element forms the tension force. The elastic element can be any elastic element that can generate tension force when the first support 121 and the second support 122 approach each other, such as a tension spring, elastic band, or rubber rope. By making the tensioning element 130 an elastic element, the elastic force of the elastic element automatically pulls the first support 121 and the second support 122 back to a close state, realizing automatic approach between the first support 121 and the second support 122. This reduces manual intervention and simplifies operation. At the same time, the presence of the elastic element also ensures that the first support 121 and the second support 122 maintain a certain elastic connection when they separate, preventing structural loosening or loss of control and improving the overall stability of the support assembly 120. In addition, the structure of the elastic element is relatively simple and does not require additional components, so installation is convenient and the procurement and manufacturing costs are correspondingly reduced.

[0220] With the tension member 130 being an elastic member, optionally, in one embodiment of this utility model, please refer to... Figure 9、 Figure 10 、 Figure 11 and Figure 70 The elastic member is a tension spring, two ends of the tension spring are connected with the first support 121 and the second support 122 respectively, and spring force generated by the tension spring forms the pulling force. The setting position of the tension spring on the first support 121 and the second support 122 is not limited, for example, the tension spring can be arranged in the area of the first support 121 and the second support 122 where the plug-in part 151 and the clamping groove 152 are not arranged, or the tension spring can be arranged between the plug-in part 151 and the clamping groove 152. The extension direction of the tension spring is consistent with the sliding direction of the first support 121 and the second support 122. It should be noted that when the first support 121 and the second support 122 are located at the close position, the tension spring also needs to have a certain spring force at this time, so as to still generate a certain pulling force on the first support 121 and the second support 122 at the close position. Since the tension spring is usually a standard part, it is convenient to purchase, and there are more optional specifications and models, which is beneficial to the compact design of the structure.

[0221] Please refer to Figure 21 、 Figure 22 and Figure 25 In an embodiment of the present application, the first support 121 and the second support 122 are provided with mounting cavities 124, and the tension spring is arranged in the mounting cavities 124. The mounting cavities 124 can be partially arranged on the plug-in part 151 of the first support 121 and partially arranged in the clamping groove 152 of the second support 122. The shape of the mounting cavity 124 can be a variety of shapes such as a cuboid and a cylinder which can accommodate the tension spring. In another embodiment, the mounting cavities 124 can be arranged only on the plug-in part 151 of the first support 121. In other embodiments, the mounting cavities 124 can be arranged only in the clamping groove 152 of the second support 122. By arranging the mounting cavities 124, the tension spring can be protected, and the probability of the tension spring being stuck due to impurities or particles falling on the tension spring can be reduced.

[0222] Specifically, please refer to Figure 21 、 Figure 22 and Figure 25In the embodiment, the first support 121 is provided with a first mounting cavity 1241, and an opening of the first mounting cavity 1241 faces the second support 122. The second support 122 is provided with a second mounting cavity 1242, and an opening of the second mounting cavity 1242 faces the first support 121. The first mounting cavity 1241 and the second mounting cavity 1242 are coaxially arranged, and an outer diameter of the second mounting cavity 1242 is less than or equal to an 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 support 121 is provided with a first connecting column 131, and the first connecting column 131 penetrates the first mounting cavity 1241 in a radial direction of the first mounting cavity 1241. The second support 122 is provided with a second connecting column 132, and the second connecting column 132 penetrates the second mounting cavity 1242 in a 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 to the first connecting column 131, and the other end of the tension spring is located in the second mounting cavity 1242 and is hooked to the second connecting column 132.

[0223] The outer support assembly 140 is arranged between the first support 121 and the second support 122 to change the distance between the first support 121 and the second support 122. The outer support assembly 140 can have various structural forms, and optionally, refer to Figure 14 and Figure 17 In an embodiment of the utility model, the outer support assembly 140 includes a seat body 141 and a first outer support 142. In the length direction of the support assembly 120, one end of the first support 121 and one end of the second support 122 are both connected to the seat body 141 in a plug-in manner. The plug-in connection mode can be various, for example, the end of the first support 121 and the end of the second support 122 can be provided with a columnar protrusion, and the seat body 141 is correspondingly provided with a plug-in hole, and the columnar protrusion can be plugged into the plug-in hole to realize the plug-in connection between them. The end of the first support 121 and the end of the second support 122 can also be provided with a plug-in hole, and the seat body 141 is correspondingly provided with a plug-in columnar protrusion, and the plug-in columnar protrusion can be plugged into the plug-in hole, so that the plug-in connection between them can also be realized.

[0224] The first outer support 142 is arranged at one end of the first support 121 and the second support 122 away from the seat body 141, and can be slidably inserted between the first support 121 and the second support 122 to realize the mutual separation of the first support 121 and the second support 122, so as to form a first interval between the first support and the second support to tighten the cleaning element. At the same time, the first connecting column 131 and the second connecting column 132 are away from each other, the tension spring is stretched, and the elastic force is stored. Correspondingly, when the first outer support 142 slides out of the first support 121 and the second support 122, the first connecting column 131 and the second connecting column 132 are close to each other under the action of the elastic force of the tension spring, and then drive the first support 121 and the second support 122 to be close to each other, so as to form a second interval between the first support 121 and the second support 122 to relax the cleaning element 110. The first outer support 142 can be wedge-shaped structure, cylindrical, long strip-shaped and other structures, as long as it can make the first outer support 142 slide into the first support 121 and the second support 122, and gradually separate the first support 121 and the second support 122, so that the interval between the first support 121 and the second support 122 gradually increases to the second interval.

[0225] By setting the outer support assembly 140 as two parts of the seat body 141 and the first outer support 142, the 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 121 and one end of the second support 122 are connected to the seat body 141 by insertion, the seat body 141 needs to support the first support 121 and the second support 122, which is equivalent to the support part of the outer support assembly 140, so the seat body 141 needs to have high support strength in design to provide stable support for the first support 121 and the second support 122. Since the first outer support 142 needs to slide between the first support 121 and the second support 122 to realize the mutual separation or mutual approach of the first support 121 and the second support 122, the first outer support 142 is equivalent to the movable part of the outer support assembly 140, so the sliding factor needs to be considered more in the design of the first outer support 142 to slide smoothly between the first support 121 and the second support 122. Therefore, the split design of the fixed part and the movable part can facilitate flexible design of each part, and is more conducive to the structural optimization of the outer support assembly 140.

[0226] In order to further enhance the support strength of the outer support assembly 140 to the first support 121 and the second support 122, optionally, please refer to Figure 7 , Figure 8And, in an embodiment of the utility model, outer support assembly 140 still includes the casing 180 that is established above cleaning part 110, casing 180 is covered above cleaning part 110, one end of casing 180 is connected with seat body 141, the other end of casing 180 extends along the length direction of support assembly 120 and covers the length of entire cleaning part 110. Casing 180 and seat body 141 are enclosed to form the receiving cavity 190, the end of receiving cavity 190 away from seat body 141 is provided with opening 191, support assembly 120 and cleaning part 110 are installed into receiving cavity 190 from opening 191, and one end of support assembly 120 is blocked at opening 191.

[0227] Specifically, in the embodiment, please refer to Figure 17 And Figure 18 First support 121 includes casing connecting portion 1212 and support main body 1213, support main body 1213 is oppositely arranged with second support 122, is used for cooperating with second support 122 to support winding cleaning part 110. The end of second support 122 away from seat body 141 is slidably connected to casing connecting portion 1212. Casing connecting portion 1212 is blocked at the opening 191 of receiving cavity 190 and is detachably connected with casing 180. The detachable connection mode includes clamping connection, bolt detachable connection and the like. In the embodiment, in order to facilitate the disassembly between support assembly 120 and casing 180, casing connecting portion 1212 is clamped and connected with casing 180.

[0228] In another embodiment, second support 122 can also be provided with casing connecting portion 1212, first support 121 is slidably connected to casing connecting portion 1212, and casing connecting portion 1212 is connected with casing 180, and the connection between first support 121 and second support 122 and casing 180 can also be realized. In other embodiments, first support 121 and second support 122 can also be respectively provided with casing connecting portion 1212, and first support 121 and second support 122 are connected with casing 180 through the casing connecting portion 1212 of each of them respectively to realize the connection of first support 121 and second support 122 and casing 180.

[0229] By setting casing 180, the receiving cavity 190 formed by casing 180 and seat body 141 can form a protective effect on cleaning part 110, which can prevent cleaning part 110 from being damaged by external force during operation, and is beneficial to prolong the service life of cleaning part 110. At the same time, since the two ends of casing 180 are connected with seat body 141 and first support 121 and second support 122 respectively, the support strength of first support 121 and second support 122 can be effectively improved, which is beneficial to improve the stability of cleaning assembly 100 during cleaning operation.

[0230] Since there is mutual approaching pulling force between the first support 121 and the second support 122, the first outer support 142 will also be subjected to the extrusion force of the first support 121 and the second support 122 when sliding between the first support 121 and the second support 122. In order to prevent the first outer support 142 from sliding out of the first support 121 and the second support 122 under the action of the extrusion force, and to ensure the stability of the support assembly 120 supporting the cleaning piece 110, optionally, in an embodiment of the utility model, please refer to Figures 32 to 36 , the shell 180 is provided with a first clamping portion 1801 at one end away from the seat body 141, and the first clamping portion 1801 can be a clamping groove structure, a protruding structure, etc. The first outer support 142 comprises an inner support arm 1422, a second clamping portion 1423 and an end cover 1424, and 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 clasp structure matched with the first clamping portion 1801. The end of the inner support arm 1422 away from the end cover 1424 can be slidably inserted between the first support 121 and the second support 122 to realize the mutual separation between the first support 121 and the second support 122. When the interval between the first support 121 and the second support 122 is the second interval, the first clamping portion 1801 and the second clamping portion 1423 can be mutually clamped and fixed.

[0231] By setting the first clamping portion 1801 and the second clamping portion 1802, when the first clamping portion 1801 and the second clamping portion 1423 are mutually clamped and fixed, not only can the relative fixed installation between the first outer support 142 and the shell connecting portion 1212 be realized, but also the fixed connection between the support assembly 120 and the shell 180 can be realized.

[0232] Specifically, in the embodiment, please refer to Figures 35 to 39The shell connecting part 1212 is provided with a through clamping groove 1215, the clamping groove 1215 is provided with a baffle 1216, the baffle 1216 divides the clamping groove 1215 into a first hole 12151 and a second hole 12152. The first hole 12151 is in communication with the accommodating cavity 190. The side of the shell 180 away from the cleaning piece 110 is provided with a avoiding groove 1802, the first clamping part 1801 is arranged in the avoiding groove 1802, the second hole 12152 is in communication with the avoiding groove 1802. When the first outer supporting piece 142 is inserted into the clamping groove 1215, the inner supporting arm 1422 is inserted into the first hole 12151 between the first support 121 and the second support 122 to separate the first support 121 and the second support 122. The second clamping part 1423 is inserted into the avoiding groove 1802 from the second hole 12152 and is clamped with the first clamping part 1801 in the avoiding groove 1802, thereby limiting the movement of the first outer supporting piece 142 to the outside of the clamping groove 1215. The end cover 1424 is correspondingly clamped into the clamping groove 1215, and the baffle 1216 is stopped in the end cover 1424 along the depth direction of the clamping groove 1215 to limit the end cover 1424 to continue to enter the inside of the clamping groove 1215, thereby the insertion depth of the first outer supporting piece 142 between the first support 121 and the second support 122 can be limited.

[0233] In the condition that the first clamping part 1801 and the second clamping part 1423 meet the clamping requirement, the specific clamping structure of the first clamping part 1801 and the second clamping part 1423 is not limited, for example, it can be a hook clamping structure, the first clamping part 1801 is arranged as a hook, the second clamping part 1423 is arranged as a corresponding groove or hole, and the clamping is realized by clamping the hook into the groove or hole. It can also be a matching structure of a protrusion and a groove, the first clamping part 1802 is arranged as a protrusion, the second clamping part 1423 is arranged as a corresponding groove, and the clamping is realized by matching the protrusion and the groove. Optionally, Figures 33 to 36 In the embodiment, the first clamping part 1801 includes a first clamping hook 18011, and the second clamping part 1423 includes a second clamping hook 14231. Along the sliding direction of the first outer supporting piece 142, the opening of the first clamping hook 18011 is directed away from the clamping groove 1215, and the opening of the second clamping hook 14231 is directed close to the clamping groove 1215. The end cover 1424 can move in the direction that the first support 121 and the second support 122 move relative to each other in the clamping groove 1215, such as the direction of the arrow A in the figure. Figure 35The end cap 1424 has a first installation position and a second installation position in the buckle slot 1215 in the sliding direction. When the end cap 1424 is in the first installation position, the first buckle 18011 and the second buckle 14231 are disengaged from each other in the direction in which the first support 121 and the second support 122 move relative to each other. At this time, the first outer support 142 can move freely in the insertion direction. When the end cap 1424 is in the second installation position, the first buckle 18011 and the second buckle 14231 are engaged with each other, thereby limiting the movement of the first outer support 142 towards the outside of the buckle slot 1215. At the same time, the restriction of the movement of the end cap 1424 towards the inside of the buckle slot 1215 by the baffle 1216 in the buckle slot 1215 can achieve the limiting of the first outer support 142 in the sliding direction.

[0234] In some other embodiments, referring to Figures 157 to 160 , the inner support arm 1422 of the first outer support 142 is further provided with a fifth buckle 14203, and the housing connecting portion 1212 is further provided with a fourth buckle 12122 near the first hole 12151, which cooperates with the fifth buckle 14203. The engagement direction between the fifth buckle 14203 and the fourth buckle 12122 is consistent with the sliding direction of the end cap 1424 in the buckle slot 1215. When the end cap 1424 is in the first installation position, the fifth buckle 14203 and the fourth buckle 12122 are disengaged from each other. When the end cap 1424 is in the second installation position, the fifth buckle 14203 and the fourth buckle 12122 are engaged with each other, thereby limiting the probability of the inner support arm 1422 being pulled out of the first hole 12151, and further improving the stability of the outer supporting effect of the first outer support 142 on the first support 121 and the second support 122.

[0235] With the above buckling structure, when the first outer support 142 needs to be fixed after being inserted between the first support 121 and the second support 122, the end cap 1424 in the buckle slot 1215 is slid from the first installation position to the second installation position, and the first buckle 18011 and the second buckle 14231 are engaged with each other. Conversely, when the first outer support 142 needs to be slid out of the first support 121 and the second support 122, the end cap 1424 is slid in the opposite direction, so that the end cap 1424 is slid from the second installation position to the first installation position, so that the first buckle 18011 and the second buckle 14231 are disengaged from each other, i.e. the engagement relationship between the first buckle 18011 and the second buckle 14231 is released, and the first outer support 142 can move freely in the sliding direction.

[0236] It should be noted that the number of the first buckles 18011 and the second buckles 14231 can be one or multiple, as long as the buckle strength requirement is met. Optionally, in the embodiment, the number of the first buckles 18011 and the second buckles 14231 is two, one first buckle 18011 corresponds to one second buckle 14231. Such a setting can form two clamping connection points when the first clamping part 1801 and the second clamping part 1423 are clamped with each other, thereby facilitating to improve the clamping stability of the first outer support 142 in the buckle slot 1215.

[0237] Optionally, in another embodiment, referring to Figure 40 and Figure 41 , the first outer support 142 can further include a first connecting part 14201 and a second connecting part 14202, the first connecting part 14201 and the second connecting part 14202 are two independent split structures. The first connecting part 14201 includes the inner support arm 1422 and the first end cover 14241, the second connecting part 14202 includes the second clamping part 1423 and the second end cover 14242, and the first end cover 14241 and the second end cover 14242 combine to form the above-mentioned end cover 1424. When the first outer support 142 needs to be inserted into the buckle slot 1215, the first connecting part 14201 and the second connecting part 14202 can be inserted into the buckle slot 1215 separately. Such a setting can also achieve the clamping connection between the first outer support 142 and the shell 180, and has the beneficial effects of the above-mentioned embodiments.

[0238] Optionally, referring to Figure 33 , Figure 35 and Figure 42 , in an embodiment of the utility model, the shell 180 includes a guide wall 1803, the guide wall 1803 is arranged in the avoiding slot 1802, and the guide wall 1803 extends along the sliding direction of the first outer support 142. The shell connecting part 1212 further includes a guide 12121, the guide 12121 is inserted into the avoiding slot 1802 and is close to the guide wall 1803. The number of the guide wall 1803 is not limited, which can be one or two. Optionally, in the embodiment, the guide wall 1803 is provided with two, and the two guide walls 1803 are oppositely arranged along the length direction of the avoiding slot 1802. It should be noted that the length direction of the avoiding slot 1803 is the same as the moving direction of the first support 121 and the second support 122, as shown by the direction W4 in Figure 33 .

[0239] The guide 12121 and the guide wall 1803 are arranged and matched with each other, so that the guide effect is achieved when the shell connecting part 1212 is connected with the shell 180, the connection of the shell connecting part 1212 and the shell 180 is facilitated, and the installation between the support assembly 120 and the shell 120 is facilitated. Meanwhile, the guide 12121 and the guide wall 1803 are close to each other, and a friction force is generated between the guide 12121 and the guide wall 1803. The friction force helps the support assembly 120 to keep a stationary state relative to the shell 180, so that the possibility that the first outer support 142 is separated from between the first support 121 and the second support 122 in the sliding direction is further reduced.

[0240] In order to improve the smoothness of the sliding of the first outer support 142 between the first support 121 and the second support 122, optionally, in an embodiment of the utility model, referring to Figure 15 、 Figure 20 、 Figure 40 and Figure 43 , the side of the first outer support 142 facing the second support 122 comprises a first guide inclined surface 1421. The second support 121 comprises a second guide inclined surface 127, and the first guide inclined surface 1421 slides along the second guide inclined surface 127 to realize the mutual approach or separation of the first support 121 and the second support 122. In another embodiment, the side of the first outer support 142 facing the first support 121 can also comprise a first guide inclined surface 1421. The first support 121 comprises a second guide inclined surface 127, and the first guide inclined surface 1421 slides along the second guide inclined surface 127. In other embodiments, the first outer support 142 can also be provided with the first guide inclined surface 1421 on both sides facing the first support 121 and the second support 122, and the second support 121 and the second support 122 are both provided with the second guide inclined surface 127. The first guide inclined surface 1421 on both sides of the first outer support 142 respectively slides with the second guide inclined surface 127 on the corresponding side.

[0241] Through the cooperation of the first guide inclined surface 1421 and the second guide inclined surface 127, the sliding of the first outer support 142 between the first support 121 and the second support 122 can be guided, the probability of deviation or misalignment in the sliding process is reduced, and the smoothness of the separation and approach process of the first support 121 and the second support 122 is improved. Moreover, the mutual contact of the first guide inclined surface 1421 and the second guide inclined surface 127 can form a larger contact area between the first outer support 142 and the first support 121 and the second support 122 when the first support 121 and the second support 122 are in a separated state, which is beneficial to reduce the probability of displacement and separation of the first outer support 142.

[0242] In order to further reduce the probability of skew displacement of the first outer support 142 when sliding between the first support 121 and the second support 122, and ensure the smoothness of sliding, optionally, in an embodiment of the utility model, please refer to Figure 18 、 Figure 20 and Figure 44 , the first guide slope 1421 is arranged on the side of the first outer support 142 facing the second support 122, and the second guide slope 127 is arranged on the second support 122. As shown in Figure 18 , the first support 121 is provided with a sliding groove 125 at the end away from the seat body 141, and the sliding groove 125 is arranged opposite to the first outer support 142. The side of the first outer support 142 away from the first guide slope 1421 is at least partially accommodated in the sliding groove 125. In the height direction of the support assembly 120, the upper wall of the sliding groove 125 abuts against the upper side of the first outer support 142, the lower wall of the sliding groove 125 abuts against the lower side of the first outer support 142, and the bottom wall of the sliding groove 125 abuts against the side wall of the first outer support 142 away from the first guide slope 1421.

[0243] In other embodiments, the first guide slope 1421 can also be arranged on the side of the first outer support 142 facing the first support 121, and the second guide slope 127 is arranged on the first support 121. The second support 122 is provided with a sliding groove 125 at the end away from the seat body 141, and the side of the first outer support 142 away from the first guide slope 1421 is at least partially accommodated in the sliding groove 125.

[0244] By arranging the sliding groove 125, when the first outer support 142 slides between the first support 121 and the second support 122, the side of the first outer support 142 away from the first guide slope 1421 can slide along the sliding groove 125. At the same time, the sliding groove 125 can also guide and limit the first outer support 142 in the height direction of the support assembly 120, further reducing the probability of skew displacement of the first outer support 140 during sliding, thereby further ensuring the smoothness of sliding of the first outer support 142 between the first support 121 and the second support 122.

[0245] Further, in order to prevent the first outer support 142 from falling out of the first support 121 and the second support 122 during sliding, optionally, in an embodiment of the utility model, please refer to Figure 9 、 Figure 36 、 Figure 44 and Figure 45The first support 121 is provided with a limiting rod 126 penetrating through the sliding groove 125 in the height direction. The limiting rod 126 can be connected to the first support 121 by insertion or fixedly connected to the first support 121 by screwing. The first outer support 142 is provided with a limiting groove 1425, the two ends of the limiting groove 1425 in the length direction are closed ends, and the length direction of the limiting groove 1425 is consistent with the sliding direction of the first outer support 142. The limiting rod 126 is arranged in the limiting groove 1425 and slides along the limiting groove 1425. The width of the limiting groove 1425 is greater than the outer diameter of the limiting rod 126, so as to provide a space for the first support 121 and the second support 122 to approach and move away from each other.

[0246] 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 142 between the first support 121 and the second support 122. On the other hand, the limiting rod 126 cooperates with the limiting groove 1425, which can also prevent the first outer support 142 from falling out of the first support 121 and the second support 122, thereby preventing the loss of the first outer support 142.

[0247] In order to realize the insertion connection between the support assembly 120 and the seat body 141, optionally, in an embodiment of the utility model, please refer to Figure 15 and Figure 46 The first end of the first support 121 close to the seat body 141 is connected with a first mounting part 1217, and the first end of the second support 122 close to the seat body 141 is connected with a second mounting part 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 connection with the first mounting part 1217, and the second docking interface 1412 is used for docking connection with the second mounting part 1222. The outer support assembly 140 further comprises a second outer support 143, one end of the second outer support 143 is connected with the seat body 141, and the other end of the second outer support 143 is slidably inserted between the first mounting part 1217 and the second mounting part 1222. When the second outer support 143 is inserted between the first mounting part 1217 and the second mounting part 1222, the first mounting part 1217 and the second mounting part 1222 are separated along the width direction of the support assembly 120, so that the first mounting part 1217 is inserted into the first docking interface 1411, the second mounting part 1222 is inserted into the second docking interface 1412, and the insertion connection between the first support 121 and the second support 122 and the seat body 141 is realized.

[0248] The second outer supporting piece 143 is arranged at one end of the seat body 141 and is slidingly inserted between the first mounting portion 1217 and the second mounting portion 1222, so that the first support 121 and the second support 122 are separated at the end close to the seat body 141, and the first support 121 and the second support 122 are kept in the separated state, thereby playing the role of the outer supporting piece. In this way, the first support 121 and the second support 122 are conveniently connected with the seat body 141 through the plug-in connection, and the connection efficiency between the support assembly 120 and the seat body 141 is improved.

[0249] To improve the sliding plug-in precision of the second outer supporting piece 143 relative to the support assembly 120, the second outer supporting piece 143 is provided with an abutting portion 1431 at the end away from the seat body 141 in an embodiment of the utility model. Figure 17 、 FIG. 46 and FIG. 47 The abutting portion 1431 includes two groups, one group of the abutting portion 1431 is arranged on the side wall of the second outer supporting piece 143 facing the first mounting portion 1217, and the other group of the abutting portion 1431 is arranged on the side wall of the second outer supporting piece 143 facing the second mounting portion 1222.

[0250] The first mounting portion 1217 and the second mounting portion 1222 are respectively provided with a third guide inclined surface 1204 on the two oppositely arranged side wall bodies. FIG. 15 、 FIG. 17 、 FIG. 23 、 FIG. 47 and FIG. 48 Each side of the abutting portion 1431 corresponds to a same-side third guide inclined surface 1204, and in the process of sliding plug-in of the second outer supporting piece 143 in the first mounting portion 1217 and the second mounting portion 1222, the abutting portion 1431 slides along the third guide inclined surface 1204, so as to realize the mutual separation or mutual approach of the first mounting portion 1217 and the second mounting portion 1222, and further realize the mutual approach or mutual separation of the first support 121 and the second support 122 at the end close to the seat body 141.

[0251] The abutting portion 1431 can be an inclined surface structure or a combination structure of a plane and an inclined surface. Optionally, referring to FIG. 17 and FIG. 48 In this embodiment, the abutting portion 1431 includes an inclined surface segment 1434 and a plane segment 1433 connected with each other, and the plane segment 1433 is connected to the end of the inclined surface segment 1434 away from the seat body 141. The first support 121 and the second support 122 are respectively provided with a plane guide segment 1205 on the two oppositely arranged side wall bodies. FIG. 49As shown, when the first support 121 and the second support 122 are close to each other, the two side plane guide sections 1205 are close to each other to limit the close distance between the first support 121 and the second support 122. As shown, FIG. 50 As shown, when the first support 121 and the second support 122 are separated from each other, i.e., when the second outer support 143 is slidingly inserted between the first mounting portion 1217 and the second mounting portion 1222, the two side plane guide sections 1205 are gradually separated to form an insertion area 1206 for the abutting portion 1431 to be inserted, and the two side plane sections 1433 are respectively abutted on the two side plane guide sections 1205.

[0252] Please refer to FIG. 48 and FIG. 50 When the second outer support 143 is inserted between the first mounting portion 1217 and the second mounting portion 1222, the two side plane sections 1433 on the abutting portion 1431 first slide along the corresponding third guide inclined surfaces 1204, and gradually slide the two side inclined sections 1434 into the two third guide inclined surfaces 1204. With the separation of the first support 121 and the second support 122, the two side plane guide sections 1205 are gradually separated to form the insertion area 1206. The abutting portion 1431 continues to slide, and the front end plane section 1433 gradually enters the insertion area 1206 and abuts against the corresponding side plane guide section 1205, and the rear end inclined section 1434 gradually abuts against the third guide inclined surface 1204. At this time, it indicates that the second outer support 143 is inserted in place, and the insertion action is stopped.

[0253] Through the cooperation of the third guide inclined surface 1204 and the plane guide section 1205, the plane section 1433 and the inclined section 1434 of the abutting portion 1431 can be gradually slid into and accurately positioned. In this way, on the one hand, it can reduce the probability of deviating from the preset direction of the second outer support 143 during sliding between the first support 121 and the second support 122, thereby improving the positional accuracy of the insertion connection of the second outer support 143 and ensuring the consistency of multiple insertion connections. On the other hand, after the insertion of the second outer support 143 is completed, due to the mutual contact of the plane section 1433 and the plane guide section 1205, and the mutual close of the inclined section 1434 and the third guide inclined surface 1204, the external load generated between the second outer support 143 and the support assembly 120 can be effectively dispersed. This load dispersion mechanism can enhance the overall stability and carrying capacity of the connection structure between the support assembly 120 and the seat body 141, while also helping to reduce local stress concentration and prolong the service life of the structure.

[0254] In the condition that the outer support assembly 140 comprises the first outer support 142 and the second outer support 143, the dismounting mode between the support assembly 120 and the outer support assembly 140 can be various. In an embodiment, when the support assembly 120 needs to be mounted on the outer support assembly 140, the first outer support 142 can be inserted into one end of the first support 121 and the second support 122 outside the shell 180 firstly, and then the support assembly 120 is moved to the inside of the accommodating cavity 190, so that the second outer support 143 is inserted between the first support 121 and the second support 122, thereby completing the connection between the support assembly 120 and the outer support assembly 143, and also realizing the tensioning of the cleaning element 110. Correspondingly, when the support assembly 120 needs to be dismounted from the outer support assembly 140, the first outer support 142 can be firstly 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 accommodating cavity 190, so that the second outer support 143 is slid out from between the first support 121 and the second support 122, thereby completing the dismounting between the support assembly 120 and the outer support assembly 140, and also realizing the relaxation of the cleaning element 110.

[0255] In another embodiment, when the support assembly 120 needs to be mounted on the outer support assembly 140, the support assembly 120 can also be moved to the accommodating cavity 190 together with the cleaning element 110 and the first outer support 142 firstly, so that the second outer support 143 is inserted between the first support 121 and the second support 122 firstly, and then the first outer support 142 is slid and inserted between the first support 121 and the second support 122, thereby realizing the connection between the support assembly 120 and the outer support assembly 140, and also realizing the tensioning of the cleaning element 110. Correspondingly, when the support assembly 120 needs to be dismounted from the outer support assembly 140, the support assembly 120 can be firstly moved to the outside of the accommodating cavity 190, so that the second outer support 143 is slid out from between the first support 121 and the second support 122, and then the first outer support 142 is slid out from between the first support 121 and the second support 122, thereby realizing the dismounting between the support assembly 120 and the outer support assembly 140, and also realizing the relaxation of the cleaning element 110. In actual use, the user can select according to the operation habit.

[0256] In order to further improve the insertion positioning precision between the second outer support 143 and the first support 121 and the second support 122, optionally, in an embodiment of the utility model, please refer to FIG. 27 、 FIG. 28 、 FIG. 47 and FIG. 48The second outer supporting piece 143 further comprises a plurality of insertion grooves 1432, one group of the insertion grooves 1432 is arranged on the side of the first mounting part 1217, and the other group of the insertion grooves 1432 is arranged on the side of the second mounting part 1222. The first mounting part 1217 and the second mounting part 1222 are provided with a plurality of clamping blocks 128 matched with the insertion grooves 1432 on the two opposite side walls, the clamping blocks 128 are inserted into the insertion grooves 1432 and can slide along the insertion grooves 1432. In the height direction of the support assembly 120, the upper wall of the insertion groove 1432 abuts against the upper side wall of the clamping block 128, and the lower wall of the insertion groove 1432 abuts against the lower side wall of the clamping block 128. By arranging the insertion grooves 1432 and the clamping blocks 128, the insertion grooves 1432 and the clamping blocks 128 can be matched to realize the positioning in the height direction of the support assembly 120 when the second outer supporting piece 143 is inserted between the first support 121 and the second support 122. Therefore, the insertion and positioning accuracy between the second outer supporting piece 143 and the first support 121 and the second support 122 can be further improved, and the insertion and connection efficiency between the first support 121 and the second support 122 and the seat body 141 can be correspondingly improved.

[0257] In order to improve the cleaning efficiency of the cleaning piece 110 and reduce the replacement frequency of the cleaning piece 110, optionally, in an embodiment of the utility model, referring to FIG. 4 and FIG. 31 The support assembly 120 further comprises a first roller 1201 and a second roller 1202, the first roller 1201 is rotatably installed on the outer side of the first support 121, i.e. on the side of the first support 121 away from the second support 122. The second roller 1202 is rotatably installed on the outer side of the second support 122, i.e. on the side of the second support 122 away from the first support 121, and the second roller 1202 is arranged in parallel with the first roller 1201.

[0258] The cleaning piece 110 is wound around the outer circumferential surface of the first roller 1201 and the second roller 1202, and the first roller 1201 and the second roller 1202 can drive the cleaning piece 110 to rotate when rotating. It should be noted that the first roller 1201 and the second roller 1202 can be unpowered rollers, i.e. rotating through the friction force between the cleaning piece 110 and the surface to be cleaned. One of the first roller 1201 and the second roller 1202 can be a powered roller, and the other one is an unpowered driven roller. For example, a driving assembly is arranged at one end of the first roller 1201 or the second roller 1202, the driving assembly drives the first roller 1201 or the second roller 1202 to rotate, and further drives the cleaning assembly 100 to rotate.

[0259] By setting the first roller 1201 and the second roller 1202, the rotating operation of the cleaning piece 110 can be realized, and then the entire outer circumferential surface of the cleaning piece 110 can be in contact with the surface to be cleaned to perform the cleaning operation. In this way, the operation area of the cleaning piece 110 can be improved, and then the replacement frequency of the cleaning piece 110 can be reduced, and the cleaning efficiency of the cleaning piece 110 can be improved.

[0260] Firstly, the following embodiment will be described in detail with respect to the connection structure between the first roller 1201 and the support assembly 120, and the first roller 1201 and the seat body 141.

[0261] Please refer to FIG. 52 and FIG. 53 , the support assembly 120 further comprises a first support seat 12011 and a second support seat 12012. The first support seat 12011 and the second support seat 12012 are respectively fixedly connected to the two ends of the first support 121 in the length direction. Among them, the first support seat 12011 is fixedly connected to one end of the first support 121 close to the shell connecting part 1212, and the fixed connection mode can be integrally injection molded connection, or fixed connection through bolts and other fasteners, etc. Optionally, in the present embodiment, please refer to FIG. 52 and FIG. 60 , the first support seat 12011 is integrally connected with the first support 121. The second support seat 12012 is detachably connected to one end of the first support 121 close to the seat body 141, and the detachable connection mode can be screw detachable connection, clamping detachable connection, etc. Please refer to FIG. 60 , FIG. 62 and FIG. 63 , the first support seat 12011 is provided with a first plug hole 12017, and the second support seat 12012 is provided with a second plug hole 12018. It should be noted that in the present embodiment, the second support seat 12012 is the same part as the first mounting part 1217 in the foregoing embodiment.

[0262] Please refer to FIG. 53 to FIG. 55 , the first roller 1201 comprises a first shaft end 12014 and a second shaft end 12015, the first shaft end 12014 is arranged close to one side of the shell connecting part 1212, and the second shaft end 12015 is arranged close to one side of the seat body 141. The first shaft end 12014 is rotatably connected with a first clamping piece 12016, and the second shaft end 12015 is rotatably connected with a second clamping piece 12019. The first clamping piece 12016 is plug-connected with the first plug hole 12017, and the second clamping piece 12019 is plug-connected with the second plug hole 12018. The first clamping piece 12016 and the first shaft end 12014, and the second clamping piece 12019 and the second shaft end 12015 can be rotatably connected through a rotary bearing, or can be rotatably connected through a shaft hole matching. Optionally, in the present embodiment, please refer toFIG. 55 The first clamping piece 12016 is rotationally connected to the first shaft end 12014 through the first rotary bearing 12005. Please refer to FIG. 56 The second clamping piece 12019 is rotationally connected with the second shaft end 12015 in a shaft hole matching mode, and the second clamping piece 12019 is made of self-lubricating material. The self-lubricating material can be polyformaldehyde-based material, polyamide-based material, metal-plastic composite self-lubricating material, etc. Specifically, the outer ring of the second clamping piece 12019 is tightly matched with the second insertion hole 12018 to realize the fixed connection of the second clamping piece 12019 relative to the second insertion hole 12018, and the inner ring of the second clamping piece 12019 is clearance matched with the second shaft end 12015 to realize the rotational connection between the second shaft end 12015 and the second clamping piece 12019. Since the wall thickness of the second clamping piece 12019 is smaller than the wall thickness of the first rotary bearing 12005, this arrangement makes the shaft diameter of the first roller 1201 core larger than the shaft diameter of the second roller 1202 core, which is conducive to increasing the overall shaft diameter of the first roller 1201 core, facilitating the subsequent connection of the first roller 1201 with the driving structure, and enabling the first roller 1201 to withstand larger torque as a power transmission roller, thereby realizing the stability of power transmission. Of course, in other embodiments, the second clamping piece 12019 can also be rotationally connected with the second shaft end 12015 through a rotary bearing.

[0263] To further improve the insertion connection efficiency of the first clamping piece 12016 and the first support seat 12011, optionally, in an embodiment, please refer to FIG. 55 The first clamping piece 12016 includes a cylindrical segment 12071 and a conical frustum segment 12072 connected with each other, and the conical frustum segment 12072 is arranged at one end of the cylindrical segment 12071 facing the first insertion hole 12017. The first insertion hole 12017 includes a cylindrical hole 12081 and a conical frustum hole 12082 connected with each other, the cylindrical hole 12081 is matched with the cylindrical segment 12071, and the conical frustum hole 12082 is matched with the conical frustum segment 12072. This arrangement has the following advantages. On the one hand, the conical frustum segment 12072 can play a role in centering and positioning at the initial stage of the insertion of the first clamping piece 12016 into the first insertion hole 12017, facilitating the smooth insertion of the first clamping piece 12016 into the first insertion hole 12017 and improving the insertion efficiency. On the other hand, since the insertion of the first clamping piece 12016 into the first insertion hole 12017 can not only form the taper surface matching between the conical frustum segment 12072 and the conical frustum hole 12082, but also form the cylindrical surface matching between the cylindrical segment 12071 and the cylindrical hole 12081, a double matching positioning structure can be formed, so as to improve the stability of the insertion connection between them. It should be noted that, in order to facilitate the axial positioning between the first clamping piece 12016 and the first support seat 12011, the first insertion hole 12017 arranged on the first support seat 12011 is a blind hole structure.

[0264] Optionally, in an embodiment, referring to FIG. 55 , the first plug-in hole 12017 comprises a first bottom wall 12091, the first bottom wall 12091 is provided with a positioning protrusion 12092, and a first positioning hole 12093 is surrounded between the positioning protrusion 12092, the side wall of the frustum hole 12082 and the first bottom wall 12091. The first clamping piece 12016 is provided with a platform 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 platform stage 120161 is used for installing the first rotary bearing 12005. The first shaft end 12014 at least partially extends into the through hole section 120162 after penetrating through the first rotary bearing 12005, and the extension length does not exceed the frustum section 12072 of the first clamping piece 12016. The frustum section 12072 of the first clamping piece 12016 is at least partially accommodated in the first positioning hole 12093, and the end face of the frustum section 12072 abuts with the first bottom wall 12091 in the axial direction. 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. In this way, the frustum section 12072 of the first clamping piece 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 piece 12016 and the first plug-in hole 12017 more accurate, and ensures the centering accuracy of the two in the assembly process. At the same time, due to the cooperation between the frustum section 12072 and the first positioning hole 12093, and the cooperation between the positioning protrusion 12092 and the through hole section 120162, the first clamping piece 12016 is easier to align when being inserted into the first plug-in hole 12017, which reduces the adjustment time and operation difficulty in the assembly process, and improves the assembly efficiency.

[0265] In order to realize the connection between the first roller 1201 and the seat body 141, optionally, in an embodiment of the utility model, referring to FIG. 54 , FIG. 63 , FIG. 64 and FIG. 67 , the second plug-in hole 12018 arranged on the second support seat 12012 is a through hole structure, and the second shaft end 12015 extends to the outside of the second plug-in hole 12018 after penetrating through the second clamping piece 12019.

[0273] In order to realize the connection between the second roller 1202 and the seat body 141, optionally, in an embodiment of the utility model, please refer to FIG. 57 、 FIG. 61 and FIG. 67 , the second connecting interface 1412 further comprises a second mounting hole 14121, and the side of the fourth supporting seat 12024 towards the seat body 141 further comprises a connecting end 120241 matched with the second mounting hole 14121, and the connecting end 120241 is plug-in connected in the second mounting hole 14121. By inserting the connecting end 120241 of the fourth supporting seat 12024 into the second mounting hole 14121 along the axial direction of the second roller 1202, the plug-in connection between the fourth supporting seat 12024 and the seat body 141 can be realized, and the connection mode is simple in structure and high in plug-in positioning precision, and is more suitable for repeated connection conditions between the second roller 1202 and the seat body 141.

[0274] Since the first roller 1201 and the second roller 1202 will be subjected to a large tension force when the cleaning member 110 is in a tensioned state, the stability of the support is affected. Therefore, in order to improve the stability of the first roller 1201 and the second roller 1202 supporting the cleaning member 110, optionally, in an embodiment of the utility model, please refer to FIG. 52 and FIG. 68 , the first roller 1201 and the second roller 1202 are further provided with a bearing section 1203 at the middle position close to the length thereof. The bearing section 1203 is a small-diameter shaft section provided on the first roller 1201 or the second roller 1202. When the cleaning member 110 is wound on the first roller 1201 and the second roller 1202, the bearing section 1203 can be in contact with the cleaning member 110 or not. Optionally, in the embodiment, please refer to FIG. 68The inner wall of the cleaning piece 110 is provided with a convex ring structure 111 corresponding to the abutting section 1203, which can be clamped with the abutting section 1203, thereby playing a role of installation and positioning of the cleaning piece 110 in the length direction of the support assembly 120. The first support 121 and the second support 122 are correspondingly provided with a support portion 129, the support portion 129 on the first support 121 extends towards the abutting section 1203 on the first roller 1201 and rotationally abuts the corresponding abutting section 1203. The support portion 129 on the second support 122 extends towards the abutting section 1203 on the second roller 1202 and rotationally abuts the corresponding abutting section 1203.

[0275] In other embodiments, the abutting section 1203 can also be provided on one of the first roller 1201 and the second roller 1202, and the support portion 129 corresponding to the abutting section 1203 is provided on the first support 121 or the second support 122. In this way, the support stability of the first roller 1201 and the second roller 1202 to the cleaning piece 110 can also be improved.

[0276] By providing the abutting section 1203 and the support portion 129, the abutting section 1203 and the support portion 129 rotationally abut, so that an additional abutting force opposite to the tensioning force of the cleaning piece 110 is formed between the two ends of the first roller 1201 and the second roller 1202, thereby offsetting part of the tensioning force of the cleaning piece 110 on the first roller 1201 and the second roller 1202, reducing the probability of bending deformation of the first roller 1201 and the second roller 1202 under stress, thereby improving the support stability of the first roller 1201 and the second roller 1202 to the cleaning piece 110.

[0277] In order to form a better friction force between the cleaning piece 110 and the first roller 1201 or the second roller 1202, and reduce the probability of slipping of the cleaning piece 110 during rotation, it is optional to refer to FIG. 53 and FIG. 56In an embodiment of the present application, the outer circumferential surface of the first roller 1201 and the second roller 1202 is at least partially made of rubber material. Here, at least partially made of rubber material means that the outer circumferential surface of the first roller 1201 and the second roller 1202 in contact with the cleaning piece 110 is at least partially made of rubber material. In an embodiment, the outer circumferential surface of the first roller 1201 and the second roller 1202 in contact with the cleaning piece 110 can be made of rubber material. Alternatively, the outer circumferential surface of one of the first roller 1201 and the second roller 1202 in contact with the cleaning piece 110 can be made of rubber material. Alternatively, the outer circumferential surface of the first roller 1201 and the second roller 1202 in contact with the cleaning piece 110 can be partially made of rubber material. The rubber material can be a rubber ring structure wrapped around the outer circumferential surface of the first roller 1201 or the second roller 1202, or can be a plurality of point-shaped rubber protrusions, strip-shaped rubber protrusions, etc. distributed on the first roller 1201 or the second roller 1202. In actual design and production, the actual rotational friction between the cleaning piece 110 and the first roller 1201 and the second roller 1202 needs to be determined. The rubber material can be hard rubber material or soft rubber material, as long as it meets the transmission requirements between the first roller 1201 and the second roller 1202 and the cleaning piece 110.

[0278] By providing rubber material on the outer circumferential surface of the first roller 1201 and the second roller 1202, the transmission friction between the cleaning piece 110 and the first roller 1201 and the second roller 1202 can be increased, the working condition of friction can be improved, and the probability of slippage of the cleaning piece 110 during rotation can be reduced, thereby improving the cleaning effect of the cleaning piece 110. At the same time, since the rubber material also has certain shock absorption and noise reduction performance, the noise generated during the operation of the cleaning assembly 100 can also be reduced, and the user experience can be improved.

[0279] Optionally, in an embodiment of the present application, referring to FIG. 6 and FIG. 31 , the cleaning assembly 100 further comprises a driving structure 160, the driving structure 160 is arranged on the seat body 141 and drives the first roller 1201 to rotate.

[0280] By setting the driving structure 160, the rotation of the driving structure 160 can drive the first roller 1201 to rotate, and the rotation of the first roller 1201 drives the cleaning piece 110 and the second roller 1202 to rotate. Since the driving structure 160 can provide stable power output, the cleaning piece 110 can obtain stable rotation speed, thereby ensuring the stability of the cleaning efficiency and the cleaning effect. At the same time, it will not be limited by the friction of the surface to be cleaned, and can be suitable for more cleaning scenes.

[0281] Optionally, in an embodiment of the utility model, please refer to FIG. 31 and FIG. 69 The driving structure 160 includes a first driving piece 161 and a gear assembly 162. The first driving piece 161 can be a motor, a hydraulic pump or any mechanism capable of realizing rotary motion. Optionally, in this embodiment, the first driving piece 161 is a motor. The input end of the gear assembly 162 is connected with the output end of the first driving piece 161, and the gear assembly 162 includes a first output end 1621 connected with the first roller 1201 to drive the first roller 1201 to rotate. The gear assembly 162 can include multiple gear transmission structures, or only one gear transmission structure, depending on the transmission connection requirements between the motor and the first roller 1201.

[0282] Since the gear assembly 162 can realize compact layout through reasonable design, the installation space on the seat body 141 can be saved, and the overall structure of the cleaning assembly 100 is more portable and compact. At the same time, the gear assembly 162 also has high transmission efficiency, which is conducive to improving the rotation efficiency of the cleaning piece 110 and reducing energy loss.

[0283] Specifically, in this embodiment, please refer to FIG. 69The gear assembly 162 comprises a first gear structure 1623 and a second gear structure 1624, and the first driving member 161 drives the first gear structure 1623 to rotate. A double-layer gear structure is arranged on an output shaft of the first gear structure 1623, and is marked as a first gear 16231 and a second gear 16232 for convenience of description. The first gear 16231 is in transmission connection with the second gear structure 1624, so as to drive the first roller 1201 to rotate, and further drive the cleaning member 110 to rotate. An output end of the second gear structure 1624 forms a first output end 1621 of the gear assembly 162. The first output end 1621 is provided with a first output gear 16211, and the first output gear 16211 is installed on the first connecting shaft 12001. When the first output gear 16211 rotates, the first connecting shaft 12001 is driven to rotate, and further the first roller 1201 is driven to rotate. The seat body 141 is provided with a containing cavity 1413 on a side away from the second outer supporting member 143, and the gear assembly 162 is arranged in the containing cavity 1413. An opening position of the containing cavity 1413 is further provided with a gear box cover 14131, and the gear box cover 14131 is detachably connected to the seat body 141. The first gear structure 1623 and the second gear structure 1624 are both conventional gear train structures, and will not be described herein.

[0284] In an embodiment, referring to FIG. 5 、 FIG. 54 、 FIG. 69 The side of the gear box cover 14131, facing the first output gear 16211, is further provided with a third mounting hole 14132, and a third rotary bearing 12007 is installed in the third mounting hole 14132. An end of the first connecting shaft 12001, extending out of the first output gear 16211, is connected with the third rotary bearing 12007, so as to realize rotary support of the first connecting shaft 12001 on the gear box cover 14131. In this way, the two ends of the first output gear 16211 are respectively provided with the second rotary bearing 12003 and the third rotary bearing 12007, so that the support stability of the first connecting shaft 12001 to the first output gear 16211 can be improved.

[0285] By arranging the gear box cover 14131, the gear box cover 14131 can effectively block dust, impurities, moisture and the like in the external environment from entering the containing cavity 1413, so as to avoid mixing of these foreign matters into the gear assembly 162, thereby reducing the wear of the gear assembly and the decrease of the meshing precision, and further reducing the maintenance and replacement cost of the equipment.

[0286] In order to improve the transmission precision between the first roller 1201 and the first connecting shaft 12001, and reduce the probability of slippage between the first roller 1201 and the first connecting shaft 12001, optionally, in an embodiment, referring to FIG. 71The plug-in 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-prism structure corresponding to the polygonal hole 1415. In this way, since the polygonal hole and the multi-prism 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 cooperation between the second shaft end and the plug-in 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 of the polygonal hole and the multi-prism structure can increase the friction between them, it can effectively reduce the slipping phenomenon caused by the change of axial or radial load, so this connection structure is more suitable for high-torque or high-precision transmission scenarios.

[0287] Of course, in other embodiments, the plug-in blind hole 12002 can also be provided with a common cylindrical hole, and the second shaft end 12015 is a cylindrical structure, which is plug-in connected in the cylindrical hole. By controlling the tightness of the cooperation between the plug-in 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.

[0288] In the condition that the second shaft end 12015 and the first connecting shaft 12001 adopt the plug-in connection mode of the cooperation of the polygonal hole and the multi-prism structure, in order to further improve the stability of the power transmission between the first roller 1201 and the driving structure 160, optionally, in an embodiment, please refer to FIG. 77 to FIG. 79 , along the axial direction of the first roller 1201, the length size of the second shaft end 12015 extending to the outside of the second support seat 12012 is A, the length size of the butt joint end 12026 of the fourth support seat 12024 is B, and 0

[0289] Considering the connection efficiency between the second support 12012 and the first bracket 121, optionally, in one embodiment, please refer to... FIG. 72 The second support 12012 is snap-fitted to the first bracket 121. There are various snap-fit ​​connection methods, such as a slot and block snap-fit ​​structure. A slot is provided on one of the first bracket 121 and the second support 12012, and a matching block is provided on the other. The block is typically designed as a protrusion, while the slot is recessed; the two achieve snap-fit ​​through their shapes. Alternatively, it can be a snap-fit ​​structure using 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 12012, and a corresponding snap-fit ​​boss or groove is provided on the other. The elastic buckle deforms and snaps into the corresponding boss or groove, using elastic restoring force to achieve snap-fit ​​fixation. By snap-fitting the second support 12012 to the first bracket 121, the assembly process is simplified, eliminating the need for additional fasteners, thereby improving the connection efficiency between the second support 12012 and the first bracket 121, and reducing assembly time and operational complexity.

[0290] Specifically, in this embodiment, please refer to FIG. 73 to FIG. 76 The first bracket 121 is provided with a first mating part 1218, which extends along the length of the first bracket 121. The second support base 12012 is provided with a first mating groove 120121, the shape of which matches the first mating part 1218. The first mating part 1218 can be slidably inserted into the first mating groove 120121 along the length of the first bracket 121, and the first mating part 1218 and the first mating groove 120121 are abutted together along the length of the first bracket 121. The first mating groove 120121 includes two opposing groove sidewalls 120122 and a groove bottom wall 120123 connecting the two groove sidewalls 120122. When the first mating part 1218 is inserted into the first mating groove 120121, the two groove side walls 120122 abut against the two side surfaces of the first mating part 1218 respectively, and the groove bottom wall 120123 abuts against the bottom surface of the first mating part 1218, so as to achieve precise insertion and positioning of the second support 12012 in the width and height directions of the first bracket 121, ensuring the stability and reliability of the connection.

[0291] By setting the first matching part 1218 and the first matching groove 120121, and slidingly inserting the first matching part 1218 into the first matching groove 120121, the assembly accuracy and stability between the first support 121 and the second support base 12012 can be ensured, and the connection efficiency can be improved, and the mounting and dismounting between the second support base 12012 and the first support 121 are facilitated. Meanwhile, since the first matching part 1218 is slidingly inserted into the first matching groove 120121 along the length direction of the first support 121, when the first roller 1201 needs to be mounted on the first support 121, the first shaft end 12014 can be inserted into the first support base 12011 first, and then the second shaft end 12015 is inserted into the second support base 12012 along the axial direction of the first roller 1201. During the insertion process, the insertion connection between the first matching groove 120121 and the first matching part 1218 can be completed at the same time. In this way, the assembly steps can be simplified, the assembly time can be saved, and the assembly efficiency of the overall structure can be improved.

[0292] Optionally, in an embodiment, please continue to refer to FIG. 73 to FIG. 76 The second support base 12012 further comprises a second matching groove 120124, and the second matching groove 120124 is arranged through the groove side wall 120123. The side wall of the second matching groove 120124 is provided with a third buckle 120125. It should be noted that the third buckle 120126 can be arranged on only one side wall of the second matching groove 120124, or can be arranged on both side walls. In this embodiment, the third buckle 120126 is arranged on both side walls. The first support 121 is further provided with a second matching part 1219, and the second matching part 1219 is connected with the first matching part 1218. The side wall of the second matching part 1219 is provided with a first groove 12192 matched with the third buckle 120126. When the second support base 12012 and the first support 121 are connected by insertion, the third buckle 120126 on each side is buckled into the first groove 12192 on the same side.

[0293] In this way, when the second support base 12012 and the first support 121 are connected by insertion, the third buckle 120126 and the first groove 12192 are buckled with each other, so that the positioning connection of the second support base 12012 in the length direction of the first support 121 can be further improved, and the stability of the insertion connection between the second support base 12012 and the first support 121 can be improved.

[0294] Optionally, in an embodiment of the utility model, please refer to FIG. 73 to FIG. 76The first support 121 is provided with an avoiding arc surface 12193 on one side of the first roller 1201, which is matched with the outer circumferential surface of the first roller 1201. The avoiding arc surface 12193 is provided with two notches 12194 on one end close to the second support base 12012, and the two notches 12194 are respectively located on the two sides in the radial direction of the avoiding arc surface 12193. The second support base 12012 is provided with two transition arc surfaces 12195 on one end close to the first support 121, and the two transition arc surfaces 12195 are respectively matched with the two notches 12194. When the second support base 12012 is connected to the first support 121 in a plug-in mode, the two transition arc surfaces 12195 are respectively filled in the two notches 12194 to form an arc surface connection between the avoiding arc surface 12193 and the two transition arc surfaces 12195. In this way, through the cooperation of the avoiding 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 rotation. At the same time, the cooperation of the transition arc surfaces 121965 and the notches 12194 can realize smooth transition when the second support base 12012 is connected to the first support 121 in a plug-in mode, and can also improve the compactness of the overall structure and enhance the aesthetic appearance of the overall structure.

The first supporting end 173 is a rotating shaft structure, and the first supporting end 173 is mounted in interference fit with the sixth rotary bearing 12008, so as to realize the rotational connection of the first supporting end 173 relative to the shell 180.

[0298] Please refer to FIG. 88 , the gear assembly 162 comprises 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, and when the first gear structure 1623 rotates, the third gear structure 1625 will also rotate in addition to driving the second gear structure 1624 to rotate. The output end of the third gear structure 1625 forms a 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.

[0299] Please refer to FIG. 87 , the second supporting end 174 is arranged at one end of the roll shaft 171 close to the seat body 141 and is fixedly connected with the second output gear 16221. Specifically, the fluffing roller 170 further comprises an adapter shaft 176, and the seat body 141 further comprises a third mounting hole 1410, and the adapter shaft 176 is rotationally connected with the third mounting hole 1410 through a seventh rotary bearing 12009. One end of the adapter shaft 176 extends to the outside of the receiving cavity 190 and is fixedly connected with the second output gear 16221, and the other end of the adapter 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 supporting end 174 is a multi-rib structure corresponding to the first blind hole 1761. The second supporting end 174 is inserted into the first blind hole 1761 to realize the fixed connection of the second supporting end 174 with the adapter shaft 176, and further realize the fixed connection of the roll shaft 171 with the second output gear 16221. When the first driving member 161 rotates, the second output gear 16221 is driven to rotate, the second output gear 16221 drives the second supporting end 174 to rotate, and further drives the fluffing roller 170 to rotate relative to the shell 180.

[0300] 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, so that the entire working area of the cleaning member 110 can be fluffed by the fluffing roller 170.

[0301] Of course, in other embodiments, the length of the fluffing roller 170 can also cover only a part of the length of the cleaning member 110, which can also play a role in local fluffing.

[0302] By arranging the fluffing roller 170, the fluffing roller 170 can be fluffed when the cleaning assembly 100 is cleaning, so that the cleaning assembly 100 can be kept in a high-efficiency cleaning state, and the cleaning efficiency of the cleaning assembly 100 can be improved. At the same time, the same motor drives the cleaning assembly 100 and the fluffing roller 170 to rotate, which can save assembly space and reduce the production cost of the cleaning assembly 100.

[0303] In order to facilitate the disassembly of the fluffing roller 170 and the shell 180, optionally, in another embodiment of the utility model, please refer to FIG. 83 to FIG. 86 The connecting piece 175 and the shell 180 are connected by clamping. Specifically, the connecting piece 175 includes a clamping hook part 1752 and a protruding block part 1753, and the clamping hook part 1752 and the protruding block part 1753 are arranged at the outer periphery of the mounting hole 1751 at an angle. The shell 180 includes a clamping hook groove 1804 and a recessed groove part 1805, the clamping hook groove 1804 extends along the rotation direction of the fluffing roller 170, the clamping hook part 1752 matches the clamping hook groove 1804, and the protruding block part 1753 matches the recessed groove part 1805. When the connecting piece 175 is installed, the clamping hook part 1752 is first clamped into the clamping hook groove 1804, and then the connecting piece 175 is rotated along the clamping hook groove 1804, so that the protruding block part 1753 is clamped into the recessed groove part 1805, to realize the clamping connection between the connecting piece 175 and the shell 180. This arrangement not only realizes the stable and reliable clamping between the connecting piece 175 and the shell 180, but also simplifies the installation process and improves the assembly efficiency between the fluffing roller 170 and the shell 180, because no additional connecting parts are introduced.

[0304] 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. In this way, when the free end of the fluffing roller 170 moves relative to the cleaning member 110, the cleaning member 110 can be more easily turned up, which is beneficial to improve the fluffing effect of the cleaning member 110.

[0305] The number of gears of the second gear structure 1624 and the number of gears of the third gear structure 1625 are not limited, and in an embodiment of the utility model, please refer to FIG. 88 , the number of gears of the second gear structure 1624 is greater than the number of gears of the third gear structure 1625. In this way, the output speed and the output torque of the first output end 1621 and the second output end 1622 can be different, so that the requirements of the rotating torque and the rotating speed of the first roller 1201 and the fluffy roller 170 can be better met.

[0306] In order to realize the difference between the rotating direction of the fluffy roller 170 and the rotating direction of the cleaning piece 110, in an embodiment, please refer to FIG. 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. Alternatively, the number of gears of the second gear structure 1624 can be even, and the number of gears of the third gear structure 1625 can be odd. In this way, the output ends of the second gear structure 1624 and the third gear structure 1625 can be different, that is, the rotating directions of the first output end 1621 and the second output end 1622 can be different, so that the rotating directions of the fluffy roller 170 and the cleaning piece 110 can be different.

[0307] Under the condition that the driving structure 160 drives the first roller 1201 to rotate, in an embodiment of the utility model, please refer to FIG. 53 , the outer circumferential surface at the position where the first roller 1201 contacts the cleaning piece 110 is made of rubber. In this way, since the rubber material has a high friction coefficient, the slipping between the cleaning piece 110 and the first roller 1201 can be reduced, and the cleaning piece 110 can stably rotate with the first roller 1201, so that the cleaning effect can be improved.

[0308] Alternatively, please refer to FIG. 53In an embodiment of the present application, the first roller 1201 comprises 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 two ends of the abutting section 1203 of the first roller 1201. In an embodiment, the first driving roller 120001 and the second driving roller 120002 can be two independently arranged shaft sections, and the two shaft sections can be detachably connected through a shaft coupling, a bearing seat or the like. In this way, the weight of the first driving roller 120001 and the second driving roller 120002 can be flexibly prepared according to the requirement of gravity distribution, and thus the design is more flexible. In another embodiment, the first driving roller 120001 and the second driving roller 120002 can also share a metal inner core and cannot be detached from each other. In this way, the assembly of the first roller 1201 is facilitated, and the assembly efficiency is improved. Similarly, the second roller 1202 also comprises 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 two ends of the abutting section 1203 of the second roller 1202. In an embodiment, the first driven roller 120003 and the second driven roller 120004 can be two independently arranged shaft sections, and the two shaft sections can be detachably connected through a shaft coupling, a bearing seat or the like. In this way, the weight of the first driven roller 120003 and the second driven roller 120004 can be flexibly prepared according to the requirement of gravity distribution, and thus the design is more flexible. In another embodiment, the first driven roller 120003 and the second driven roller 120004 can also share a metal inner core and cannot be detached from each other. In this way, the assembly of the second roller 1202 is facilitated, and the assembly efficiency is improved.

[0309] Optionally, in the present embodiment, referring to FIG. 55The first roller 1201 comprises a first metal inner core 120005 and a first outer cladding layer 120051 and a second outer cladding layer 120052 which are coated on the first metal inner core 120005. The first outer cladding layer 120051 and the first metal inner core 120005 at the corresponding position form the first driving roller 120001. The second outer cladding layer 120052 and the first metal inner core 120005 at the corresponding position form the second driving roller 120002. The first outer cladding layer 120051 and the second outer cladding layer 120052 are made of soft glue material, which can be silicone, rubber or the like. It should be noted that, in order to facilitate the molding of the first outer cladding layer 120051 and the second outer cladding layer 120052 on the first metal inner core 120005, both ends of the first outer cladding layer 120051 and the second outer cladding layer 120052 are provided with a shaping piece (not shown in the figure), which is made of hard glue material. The hard glue material can be polyvinyl chloride, polypropylene or the like. In this way, the first outer cladding layer 120051 and the second outer cladding layer 120052 made of soft glue material can have greater friction, improving the transmission stability between the cleaning element 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.

[0310] Of course, in other embodiments, the material of the first outer cladding layer 120051 and the second outer cladding layer 120052 can also be hard glue material or metal material, as long as it can drive the cleaning element 110 to rotate when the first roller 1201 rotates, so that the cleaning assembly 100 can normally clean.

[0311] Considering that the cleaning assembly 100 is provided with the driving structure 160 and the seat body 141 at one end close to the seat body 141, which will cause the weight deviation at both ends of the cleaning assembly 100 in the length direction, and when cleaning, it will cause the cleaning element 110 and the surface to be cleaned to generate cleaning forces of different sizes, affecting the uniformity of the cleaning effect. Based on this, optionally, in an embodiment of the present application, please refer to FIG. 31 and FIG. 56The second roller 1202 comprises a second metal inner core 120006 and a third outer cladding layer 120061 and a fourth outer cladding layer 120062 wrapped on the second metal inner core 120006, and the fourth outer cladding layer 120062 is arranged at one end of the second roller 1202 away from the seat body 141. The third outer cladding layer 120061 and the second metal inner core 120006 at the corresponding position form a first driven roller 120003, and the fourth outer cladding layer 120062 and the second metal inner core 120006 at the corresponding position form a second driven roller 120004. The third outer cladding layer 120061 is made of soft glue material, which can be silicone, rubber or the like. The fourth outer cladding layer 120062 is made of metal material, and the fourth outer cladding layer 120062 can be the same metal material as the second metal inner core 120006 or different types of metal material, which is not limited in the embodiment. It should be noted that, in order to facilitate the molding of the third outer cladding layer 120061 on the second metal inner core 120006, the two ends of the third outer cladding layer 120061 are also provided with a shaping piece made of hard glue material. The hard glue material can be polyvinyl chloride, polypropylene or the like. In this way, on the one hand, the third outer cladding layer 120061 made of soft glue material can have greater friction to ensure that the second roller 1202 and the cleaning piece 110 have sufficient transmission friction, reduce the probability of slipping between the second roller 1202 and the cleaning piece 110, and improve the stability of the transmission of the cleaning piece 110. On the other hand, since the fourth outer cladding layer 120062 is made of metal material, under the condition of the same diameter and the same length, the mass of the second driven roller 120004 is greater than that 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, thereby being beneficial to improving the weight deviation of the cleaning assembly 100 at both ends in the length direction and improving the stability of the overall operation of the cleaning assembly 100 and the consistency of the cleaning effect.

[0312] In order to further improve the weight deviation of the cleaning assembly 100, optionally, in another embodiment of the utility model, please refer to FIG. 89The cleaning assembly 100 further comprises a counterweight 1806 arranged at one end of the shell 180 away from the driving structure 160. The counterweight 1806 can be arranged at the side of the shell 180 facing the cleaning member 110 or at the side of the shell 180 away from the cleaning member 110. Alternatively, in the embodiment, the counterweight 1806 is arranged at the side of the shell 180 away from the cleaning member 110, i.e., at the outer side of the shell 180. In this way, the counterweight 1806 is conveniently mounted on the shell 180. The counterweight 1806 can be connected to the shell 180 by clamping or fixed by bolts. Alternatively, in the embodiment, the counterweight 1806 is fixed to the shell 180 by bolts. The counterweight 1806 can be made of metal or non-metal material, and no limitation is imposed on it as long as it can meet the counterweight requirement. By arranging the counterweight 1806 at one end of the shell 180 away from the seat body 141, the weight of the cleaning assembly 100 at the end away from the driving structure 160 is increased, thereby further improving the problem of uneven weight distribution caused by the installation of the driving structure 160 at the end of the seat body 141. Therefore, this design can balance the overall gravity center of the cleaning assembly 100, reduce vibration and deviation during operation, and further improve the stability of the overall operation of the cleaning assembly 100 and the consistency of the cleaning effect. At the same time, the arrangement of the counterweight 1806 can also increase the overall weight of the cleaning assembly 100, thereby increasing the cleaning pressure between the cleaning member 110 and the ground, and further improving the cleaning effect. In addition, the counterweight 1806 can also play a role in balancing the gravity center when the cleaning assembly 100 is in the outwardly expanded position relative to the machine body 200.

[0313] The specific arrangement position and number of the counterweight 1806 are not limited as long as the counterweight requirement of the counterweight 1806 is met. Alternatively, please refer to FIG. 89 and FIG. 164 In an embodiment, the counterweight 1806 comprises a first counterweight 18061. The first counterweight 18061 can be in a plate structure, a block structure, a columnar structure, etc. In the embodiment, the first counterweight 18061 is in a flat plate structure. The first counterweight 18061 is arranged at one end of the shell 180 away from the driving structure 160 and covers the avoiding groove 1802 of the shell 180. In this way, the first counterweight 18061 not only plays a good counterweight role but also serves as a cover plate to shield the structure of the avoiding groove 1802 arranged on the shell 180, thereby improving the aesthetic appearance of the overall structure.

[0314] Please refer to FIG. 165In another embodiment, the counterweight 1806 includes a first counterweight 18061, a second counterweight 18062, and a third counterweight 18063. The second counterweight 18062 and the third counterweight 18063 are arranged on the side of the first counterweight 18061 facing the driving structure 160, and the second counterweight 18062 and the third counterweight 18063 are arranged close to the first counterweight 18061. The second counterweight 18062 and the third counterweight 18063 are arranged along the width direction of the shell 180. The first counterweight 18061, the second counterweight 18062, and the third counterweight 18063 form an integral whole at the end of the shell 180 away from the driving structure 160. The masses of the second counterweight 18062 and the third counterweight 18063 can be the same or different. In the actual design process, the mass of each counterweight 1806 needs to be determined according to the overall mass balance requirement of the cleaning assembly 100.

[0315] By arranging the first counterweight 18061, the second counterweight 18062, and the third counterweight 18063, the distributed layout of the counterweight mass on the shell 180 can be achieved, so that the overall counterweight performance of the cleaning assembly 100 can be more flexibly optimized. At the same time, by accurately controlling the mass distribution of each counterweight 1806, various counterweight combination schemes can be formed, and then the vibration characteristics under different working conditions can be accurately adjusted, so that the adjustability and optimization efficiency of the dynamic balance of the cleaning assembly 100 can be significantly improved.

[0316] Please refer to FIG. 90 to FIG. 118 In an embodiment of the utility model, a cleaning assembly 100 is also provided. The cleaning assembly 100 includes a first connecting piece 301, a second connecting piece 302, and a cleaning mechanism 303.

[0317] The first connecting piece 301 is detachably connected with the bottom of the fuselage 200, so as to realize the detachable connection between the cleaning assembly 100 and the fuselage 200. The detachable connection mode can be bolt detachable connection, clamping detachable connection, or the like. Specifically, in the embodiment, please refer to FIG. 90 to FIG. 93, the body 200 comprises a base 250, the base 250 is provided with a cleaning assembly mounting cavity 260 for accommodating the cleaning assembly 100, and the upper wall of the cleaning assembly mounting cavity 260 is provided with a plurality of mounting clamping grooves 261 and a plurality of mounting through holes 262. The side of the first connecting piece 301 facing the base 250 is provided with a plurality of mounting screw holes 3016 and a plurality of mounting buckles 3017 extending towards the side of the base 250. The plurality of mounting screw holes 3016 correspond one-to-one with the plurality of mounting through holes 262, for mounting fasteners such as bolts, screws, etc. from the side of the base 250. The plurality of mounting clamping grooves 261 correspond one-to-one with the plurality of mounting buckles 3017, and the mounting buckles 3017 are correspondingly clamped in the mounting clamping grooves 261, so as to form a pre-assembly relationship between the first connecting piece 301 and the base 250, facilitating the subsequent installation of fasteners in the mounting through holes 262 and the mounting screw holes 3016.

[0318] Please refer to FIG. 94 , the second connecting piece 302 is slidingly installed on the first connecting piece 301. The sliding installation mode can be various, for example, one of the first connecting piece 301 and the second connecting piece 302 is provided with a sliding groove, and the other is provided with a sliding block, and the sliding connection between the second connecting piece 302 and the first connecting piece 301 is realized through the cooperation of the sliding groove and the sliding block. It can also be that one of the first connecting piece 301 and the second connecting piece 302 is provided with a guide rod, and the other is provided with a guide sleeve, and the sliding connection between the second connecting piece 302 and the first connecting piece 301 is realized through the cooperation of the guide rod and the guide sleeve.

[0319] Please refer to FIG. 94 to FIG. 96 , the cleaning mechanism 303 is movably installed on the second connecting piece 302, and 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 assembly 100 in the above-mentioned embodiments, such as the cleaning piece 110, the support assembly 120, the pulling piece 130, the outer support assembly 140, and other components installed on the outer support assembly 140 and the support assembly 120. However, it can be understood by those skilled in the art that in some other embodiments, the outer support assembly 140 can also not be provided, but a conventional cleaning piece 110 tensioning structure can be used.

[0320] Please refer to FIG. 97 , the cleaning mechanism 303 and the second connecting piece 302 are provided with a lifting mechanism 304, and in the process of sliding the second connecting piece 302 relative to the first connecting piece 301, the lifting mechanism 304 drives the cleaning mechanism 303 to make lifting movement, so that the cleaning mechanism 303 is in the lifting position or the mopping position. For example, as shown in FIG. 40 , when the cleaning assembly 100 is in the mopping state, the cleaning mechanism 303 is lowered and contacts the ground under the action of the lifting mechanism 304 to clean the ground, that is, the cleaning mechanism 303 is in the mopping position. Another example is shown inFIG. 39 As shown, when the cleaning component 100 moves to the cleaning area, the cleaning mechanism 303 is raised by the lifting mechanism 304 and keeps a distance from the ground, that is, the cleaning mechanism 303 is in the raised position.

[0321] It should be noted that, in this embodiment, the sliding direction of the second connecting member 302 and 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, such as... FIG. 96 As shown on the Z1 axis. 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. 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 as follows: FIG. 96 As shown on the X1 axis. Simultaneously, the sliding direction of the second connector 302 is also along its length. This effectively utilizes the length of the cleaning mechanism 303, reducing the width of the cleaning component 100 occupied by the second connector 302 during sliding, thus promoting a more compact structural design.

[0322] The lifting mechanism 304 can be a sloped surface and slider structure. A sloped surface 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 sloped surface, thereby achieving the lifting and lowering of the cleaning mechanism 303 along the second connecting member 302. Alternatively, the lifting mechanism 304 can 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 via 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 up and down along the pulley, thereby driving the cleaning mechanism 303 connected to the rope to perform lifting and lowering movements.

[0323] The cleaning assembly 100 is provided with the lifting mechanism 304, and the lifting mechanism 304 can drive the cleaning mechanism 303 to perform lifting movement in the process that the second connecting piece 302 slides relative to the first connecting piece 301, so that the cleaning mechanism 303 is switched between the lifting position and the mopping position. In this way, on the one hand, since the lifting mechanism 304 can drive the cleaning mechanism 303 to perform lifting movement, the cleaning assembly 100 can better meet various application scenarios. For example, during the cleaning operation, when the machine body 200 passes through a carpet, the cleaning mechanism 303 can be switched to the lifting position to avoid wetting the carpet; or in the scenarios of obstacle crossing, base station returning and the like, the cleaning mechanism 303 can also be switched to the lifting position to avoid that the cleaning mechanism 303 is stuck by an obstacle and separated from the machine body 200. On the other hand, since the lifting mechanism 304 can drive the cleaning mechanism 303 to perform lifting movement in the process that the second connecting piece 302 slides relative to the first connecting piece 301, the lifting mechanism 304 can be directly driven to operate by sliding of the second connecting piece 302, without the need of additionally setting an independent lifting motor or a hydraulic system. This design not only simplifies the equipment structure, but also helps to reduce the height space of the machine body 200 occupied by the lifting mechanism 304, thereby reducing the overall height size of the cleaning assembly 100. This improves the passability of the cleaning assembly 100 in a low space, and further reduces cleaning dead angles and improves cleaning performance and use range.

[0324] Please refer to FIG. 97 to FIG. 100 In an embodiment of the utility model, the lifting mechanism 304 includes a lifting surface 3041 and a bearing part 3042, the lifting surface 3041 is arranged on the second connecting piece 302, and the bearing part 3042 is arranged on the side of the cleaning mechanism 303 facing the first connecting piece 301. The lifting surface 3041 is supported below the bearing part 3042, and the bearing part 3042 is pressed and abuts on the lifting surface 3041 by the gravity of the cleaning mechanism 303. The abutting part 1431 moves along the lifting surface 3041, and drives the cleaning mechanism 303 to realize lifting movement.

[0325] The number of the lifting surface 3041 and the bearing part 3042 can be set according to actual needs, but in the embodiment, please refer to FIG. 94 、 FIG. 97 and FIG. 98 In order to improve the stability and lifting precision of the cleaning mechanism 303, two bearing parts 3042 are arranged in the middle region of the cleaning mechanism 303 along the length direction of the cleaning mechanism 303, two lifting surfaces 3041 are correspondingly arranged on the second connecting piece 302, and the inclination directions of the two lifting surfaces 3041 are consistent. In order to facilitate the forming and positioning of the two lifting surfaces 3041, in the embodiment, the two lifting surfaces 3041 are arranged on the second connecting piece 302 (such as the second connecting piece 302 in FIG. 1) along the length direction of the second connecting piece 302, and the two lifting surfaces 3041 are arranged on the same side of the second connecting piece 302. FIG. 102The length direction array of the cleaning mechanism 303 (indicated by the X2 axis) is arranged on the second connecting piece 302. Two abutting portions 3042 abut with two lifting surfaces 3041 respectively, thereby forming two lifting points in the length direction of the cleaning mechanism 303. In this way, since the cleaning mechanism 303 is acted on by the two lifting points during lifting, the weight of the cleaning mechanism 303 can be effectively dispersed, and tilting or shaking caused by single-point force can be avoided, thereby significantly improving the stability of the lifting movement.

[0326] The specific structure 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 combination structure of an inclined surface and an arc surface, etc. The abutting portion 3042 can be 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, which is not limited in the embodiment.

[0327] By arranging the lifting surface 3041 and the abutting portion 3042, the lifting function of the cleaning mechanism 303 can be realized by abutting and cooperating the lifting surface 3041 and the abutting portion 3042, which is simple in structure design and convenient in processing. At the same time, since the abutting portion 3042 is pressed and abuts on 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 a non-driven state, thereby preventing the cleaning mechanism 303 from sliding or falling accidentally, and further improving the stability of the lifting operation of the cleaning mechanism 303. In addition, the design of gravity pressing can ensure the close contact between the abutting portion 3042 and the lifting surface 3041, so that even in the case of load change of the cleaning mechanism 303, the stable abutment between them can be maintained, and the sliding or vibration of the cleaning mechanism 303 caused by poor contact can be avoided, thereby affecting the cleaning operation.

[0328] Optionally, in an example of the utility model, referring to FIG. 97 and FIG. 100 , the second connecting piece 302 comprises a concave cavity 3021, the side of the concave cavity 3021 towards the cleaning mechanism 303 is recessed, a protruding structure 3022 is arranged inside the concave cavity 3021, the protruding structure 3022 is connected to the side wall of the concave cavity 3021 in the length direction 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 piece 302. The lifting surface 3041 is formed on the outer surface of the protruding structure 3022.

[0329] Referring to FIG. 101 , FIG. 102 and FIG. 103The bottom wall of the cavity 3021 is provided with two first through grooves 3023 along the width direction of the cavity 3021, and the two first through grooves 3023 are respectively arranged at the two sides of the protruding structure 3022 and extend along the length direction of the cavity 3021. The width direction of the cavity 3021 is consistent with the width direction of the second connecting piece 302 (as indicated by the Y2 axis in the middle) FIG. 102 Please refer to FIG. 100 and FIG. 103 The cleaning mechanism 303 is provided with two groups of connecting ends 3015 on the side facing the first connecting piece 301, each group of connecting ends 3015 corresponds to connecting one abutting part 3042, and each group of connecting ends 3015 includes two extension parts 3011. Specifically, the two extension parts 3011 are both arranged on the shell 180. One extension part 3011 corresponds to one first through groove 3023, the extension part 3011 is slidingly installed in the first through groove 3023 and at least partially extends into the cavity 3021. The abutting part 3042 is installed above the lifting surface 3041. Along the width direction of the cavity 3021, the two ends of the abutting part 3042 are respectively connected with the two extension parts 3011 on the two sides, thereby realizing the connection between the abutting part 3042 and the cleaning mechanism 303. When the abutting part 3042 moves along the lifting surface 3041, the two extension parts 3011 respectively slide along the first through grooves 3023 at the corresponding positions.

[0330] Because the protruding structure 3022 connects the side wall and the bottom wall of the cavity 3021, and the lifting surface 3041 is formed on the outer surface of the protruding structure 3022, the arrangement of the structure can improve the local support strength and rigidity of the lifting surface 3041, thereby providing stable and reliable support for the abutting part 3042, so as to ensure that the lifting surface 3041 can have good support stability in long-term use. At the same time, the two extension parts 3011 are respectively connected with the two ends of the abutting part 3042, so that a double-point connection structure is formed, the stress of the abutting part 3042 is balanced, and deformation caused by unilateral stress concentration is prevented, thereby further improving the abutting stability between the abutting part 3042 and the lifting surface 3041. Furthermore, through the cooperation of the extension part 3011 and the first through groove 3023, a preliminary guiding effect can also be achieved when the lifting surface 3041 and the abutting part 3042 move relative to each other, so that the stability of the lifting process of the cleaning mechanism 303 can be improved, and the probability of deviation or shaking can be reduced.

[0331] Optionally, in an example of the utility model, please refer to FIG. 100 , FIG. 101 FIG. 104 The lifting surface 3041 includes an inclined surface 30411. Along the depth direction of the cavity 3021, the inclined surface 30411 is inclined from the bottom wall of the cavity 3021 to the opening side of the cavity 3021. The inclination angle of the inclined surface 30411 is determined by the lifting distance of the cleaning mechanism 303. Please refer to FIG. 103The abutting part 3042 is a pin shaft fixedly connected to the cleaning mechanism 303. The two extension parts 3011 are each provided with a pin shaft mounting hole 30111, and the two ends of the pin shaft are respectively mounted in the corresponding pin shaft mounting hole 30111. The pin shaft and the pin shaft mounting hole 30111 are fixedly connected by, but not limited to, interference fit through the shaft hole. The outer circumferential surface of the pin shaft abuts against the inclined surface 30411 and slides along the lifting surface 3041.

[0332] In this embodiment, the lifting surface 3041 adopts an inclined surface structure, so that the lifting stroke of the cleaning mechanism 303 can be adjusted only by adjusting the inclination angle of the inclined surface 30411, thus having good design adaptability and being more easily matched with cleaning mechanisms 303 of various lifting stroke requirements. Meanwhile, the abutting part 3042 is set as a pin shaft, and the pin shaft is fixedly connected to the cleaning mechanism 303, so that the friction force generated when the pin shaft and the lifting surface 3041 move relative to each other can be effectively reduced, facilitating the sliding movement therebetween. In addition, since the pin shaft does not need to rotate, the connection structure between the pin shaft and the cleaning mechanism 303 is simpler, which is conducive to reducing the assembly and manufacturing cost of the cleaning assembly 100.

[0333] In an embodiment, the pin shaft can also be rotatably connected to the cleaning mechanism 303. For example, a rotary bearing can be arranged in the pin shaft mounting hole 30111 of the extension part 3011, and the two ends of the pin shaft are connected to the pin shaft mounting hole 30111 through the rotary bearing, thereby realizing the rotary connection between the pin shaft and the cleaning mechanism 303. In this way, when the pin shaft moves along the inclined surface 30411, the rolling friction between them can be reduced, which is conducive to reducing the energy consumption of the cleaning mechanism 303 during lifting operation and plays a role in energy saving. At the same time, the wear between the pin shaft and the inclined surface 30411 can also be reduced, which is conducive to improving the service life of the pin shaft and the inclined surface 30411.

[0334] 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. In this way, the rolling friction between the pin shaft and the inclined surface can also be realized, and the friction between the pin shaft and the inclined surface can be reduced.

[0335] Optionally, in an embodiment, please refer to FIG. 107The inclined surface 30411 is provided with a protruding slide strip 3043, and the outer circumferential surface of the pin shaft abuts against the surface of the slide strip 3043. The slide strip 3043 is not limited in number, and in this embodiment, two slide strips 3043 are arranged on the inclined surface 30411 on both sides in the width direction of the inclined surface 30411. In this way, the contact area between the pin shaft and the inclined surface 30411 can be reduced, thereby reducing the frictional resistance therebetween and making the sliding of the pin shaft smoother.

[0336] In order to reduce the probability of the pin shaft being pulled out of the pin shaft mounting hole, optionally, please refer to FIG. 108 In an embodiment of the utility model, the side wall of the first connecting piece 301 is provided with a first butt joint hole 3018, the side wall of the second connecting piece 302 is provided with a second butt joint hole 3024, and the first butt joint hole 3018 and the second butt joint hole 3024 are arranged on the same side in the width direction of the first connecting piece 301. When the pin shaft is located at the specified position on the inclined surface 30411, the first butt joint hole 3018, the second butt joint hole 3024 and the pin shaft mounting hole 30111 are aligned and communicated with each other, so as to realize the dismounting and mounting of the pin shaft along the axial direction of the pin shaft. When the pin shaft is located at the specified position on the inclined surface 30411, the cleaning mechanism 303 is located at the transition position between the lifting position and the mopping position. In this way, during the working process of the cleaning assembly 100, since the cleaning mechanism 303 stays at the mopping position and the lifting position most of the time, the cleaning mechanism 303 stays at the transition position other than the mopping position and the lifting position for a short time, so that the pin shaft almost does not stay at the specified position on the inclined surface 30411 for a long time. In this way, the probability of the pin shaft being pulled out of the pin seat mounting hole 30111 during the working process can be effectively reduced, so that the stability and reliability of the connection of the overall structure can be improved.

[0337] Optionally, in an embodiment of the utility model, please refer to FIG. 100 and FIG. 104 The lifting surface 3041 further comprises 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 of the inclined surface 30411 in the inclined direction. 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. As shown in FIG. 100 , when the cleaning mechanism 303 is located at the mopping position, the abutting part 3042 abuts against the first plane 30412. As shown in FIG. 98 , when the cleaning mechanism 303 is located at the lifting position, the abutting part 3042 abuts against the second plane 30413.

[0338] Specifically, please refer to FIG. 104The first plane 30412 is formed on the bottom wall of the cavity 3021, one end of the first plane 30412 is connected with the wall body on one side of the cavity 3021 in the length direction, and the other end is connected with one end of the inclined surface 30411 in the inclined direction and close to the cleaning mechanism 303. One end of the second plane 30413 is connected with the other end of the inclined surface 30411 in the inclined direction, and the other end of the second plane 30413 is connected with the wall body on the other side of the cavity 3021 in the length direction.

[0339] It should be noted that, as shown in FIG. 100 , when the abutting portion 3042 abuts against the first plane 30412, at this time the extension portion 3011 connected with the abutting portion 3042 is stopped at one end of the first through groove 3023 in the extension direction, so that the abutting position of the abutting portion 3042 on the first plane 30412 can be limited on one side in the sliding direction. As shown in FIG. 98 , when the abutting portion 3042 abuts against the second plane 30413, at this time the extension portion 3011 is stopped at the other end of the first through groove 3023 in the extension direction, so that the abutting position of the abutting portion 3042 on the second plane 30413 can be limited on the other side in the sliding direction. In this way, the sliding displacement of the second connecting piece 302 can be limited, and excessive displacement or position deviation of the second connecting piece 302 during sliding can be reduced, so that the second connecting piece 302 can move smoothly and accurately within a predetermined range.

[0340] By arranging the first plane 30412 and the second plane 30413 at both ends of the inclined surface 30411 in the inclined direction, the abutting portion 3042 can abut against the first plane 30412 and the second plane 30413 respectively when the cleaning mechanism 303 is in the mopping position and the lifting position. This design can utilize the self-gravity of the cleaning mechanism 303 to achieve self-locking between the abutting portion 3042 and the lifting surface 3041. In turn, 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.

[0341] In some embodiments, as shown in FIG. 161 to FIG. 163 , along the height direction of the second connecting piece 302, the second connecting piece 302 is provided with a shielding portion 3026 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 to shield the extension 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 piece 110 to move upward, at this time the shielding portion 3026 can effectively limit the maximum upward stroke of the cleaning piece 110 by contacting the extension portion 3011. This limiting mechanism can ensure that the cleaning piece 110 maintains stable contact pressure with the ground, thereby ensuring the consistency of the cleaning effect.

[0342] Please refer to FIG. 166 In another embodiment, the shielding part 3026 is provided with a second groove 30261 on one side facing the extension part 3011, and the extension part 3011 is provided with a protruding part 30112 matching the second groove 30261 on one side facing the shielding part 3026. When the cleaning mechanism 303 is in the mopping position, the extension part 3011 moves upward under the action of the ground reaction force, and the protruding part 30112 is correspondingly clamped into the second groove 30261. This design can limit the movement of the extension part 3011 in the outward and inward expansion direction of the cleaning piece 110, thereby improving the installation stability of the cleaning piece 110 in the horizontal direction relative to the body 200 when in the mopping position. Therefore, the probability of displacement of the cleaning piece 110 in the horizontal direction during cleaning operation can be reduced, and the cleaning effect of the cleaning piece 110 can be further improved.

[0343] In order to improve the sliding accuracy of the second connecting piece 302 relative to the first connecting piece 301 and reduce the probability of lateral deviation during sliding, optionally, in an embodiment of the utility model, please refer to FIG. 101 、 FIG. 105 、 FIG. 109 and FIG. 110 A second guide assembly 305 for guiding the sliding of the second connecting piece 302 along the first connecting piece 301 is arranged between the first connecting piece 301 and the second connecting piece 302. The second guide assembly 305 can be a guide rail and sliding block structure, one of which is arranged on the first connecting piece 301 and the other is arranged on the second connecting piece 302. Through the sliding between the sliding block and the guide rail, the sliding guide between the second connecting piece 302 and the first connecting piece 301 is realized. The second guide assembly 305 can also be a protruding block and a sliding groove structure, one of which is arranged on the first connecting piece 301 and the other is arranged on the second connecting piece 302. Through the sliding between the protruding block and the sliding groove, the sliding guide between the second connecting piece 302 and the first connecting piece 301 is realized.

[0344] By arranging the second guide assembly 305, the second guide assembly 305 can ensure that the second connecting piece 302 slides relative to the first connecting piece 301 in a predetermined direction, reduce the probability of deviation or shaking between each other during sliding, and further reduce the jamming phenomenon during sliding, which is conducive to improving the smoothness of the sliding of the second connecting piece 302.

[0345] Optionally, in an embodiment of the utility model, please refer to FIG. 101 、 FIG. 105 、 FIG. 109 and FIG. 110The second guiding assembly 305 comprises a sliding cavity 3051 and a second sliding part 3052. The sliding cavity 3051 is arranged on the first connecting member 301, and the second sliding part 3052 is arranged on the second connecting member 302. The second connecting member 302 is arranged in the sliding cavity 3051 and is in sliding connection with the sliding cavity 3051 through the second sliding part 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 closed 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 the embodiment, as shown in FIG. 109 , the two ends of the sliding cavity 3051 in the length direction are open, and the second connecting member 302 can move to the outside of the sliding cavity 3051 in the length direction during the sliding process, as shown in FIG. 105 . This arrangement is conducive to reducing the length of the first connecting member 301 and the overall weight of the cleaning assembly 100.

[0346] Please refer to FIG. 105 , FIG. 108 and FIG. 111 . The bottom wall of the second connecting member 302 is in sliding abutment with the bottom wall of the sliding cavity 3051. The bottom wall of the sliding cavity 3051 is provided with a second through slot 3053 through which the extension 3011 passes. The second through slot 3053 at least partially overlaps the first through slot 3023. Along the height direction of the cleaning mechanism 303, the extension 3011 passes through the second through slot 3053 and the first through slot 3023 in turn from bottom to top and is connected with the abutting part 3042. Please refer to FIG. 101 , FIG. 105 and FIG. 109 . The two side walls of the second connecting member 302 in the width direction form two second sliding parts 3052 respectively, and the two second sliding parts 3052 are in sliding abutment with the two side walls of the sliding cavity 3051 in the width direction (as shown by the Y3 axis in FIG. 109 ).

[0347] By arranging the sliding cavity 3051 on the first connecting member 301, the sliding of the second connecting member 302 can be guided. Moreover, the arrangement of the sliding cavity 3051 can increase the overall strength and rigidity of the first connecting member 301 and improve its carrying capacity. Meanwhile, arranging the second connecting member 302 in the sliding cavity 3051 can further reduce the installation space of the cleaning assembly 100 in the height direction and improve the compactness of the structural design.

[0348] Optionally, in an embodiment, please refer to FIG. 90 , FIG. 94 and FIG. 101The cleaning assembly mounting cavity 260 comprises an upper end wall arranged towards one side of the cleaning mechanism 303. The first connecting piece 301 is connected to the upper end wall at one end away from the cleaning mechanism 303, so as to realize the connection between the cleaning assembly 100 and the machine body 200. The upper end wall forms an upper end shielding for the sliding cavity 3051, and the second connecting piece 302 is clamped between the first connecting piece 301 and the upper end wall. The side surface of the second connecting piece 302 away from the cleaning mechanism 303 is provided with a support strip 3025, which is protruded towards one side of the upper end wall and extends along the moving direction of the second connecting piece 302 relative to the first connecting piece 301. The support strip 3025 can be provided with one or more, and in this embodiment, the support strip 3025 is provided with two, which are arranged at intervals along the width direction of the second connecting piece 302. By arranging the support strip 3025, on the one hand, the contact area between the second connecting piece 302 and the cleaning assembly mounting cavity 260 can be reduced, the friction between the second connecting piece 302 and the cleaning assembly mounting cavity 260 during movement can be reduced, and the sliding of the second connecting piece 302 can be smoother. On the other hand, the support strip 3025 is in sliding abutment with the upper end wall of the cleaning assembly mounting cavity 260, so as to avoid the movement or arch deformation of the second connecting piece 302 towards the upper end wall, and the sliding stability of the second connecting piece 302 between the upper end wall and the first connecting piece 301 is improved. On the third hand, the support strip 3025 can also increase the structural strength of the second connecting piece 302, and reduce the probability of warping or deformation of the second connecting piece 302 during use, so as to further improve the smoothness and stability of the sliding of the second connecting piece 302 relative to the first connecting piece 301.

[0349] Alternatively, in another embodiment, the support strip 3025 can also be replaced by a bearing support. The bearing support comprises a mounting seat, a connecting shaft and a bearing. The mounting seat is fixedly connected to the side wall of the second connecting piece 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 assembly mounting cavity 260. The bearing support can be provided with a plurality of bearings, and the bearings of the plurality of bearing supports roll along the moving direction of the second connecting piece 302. In this way, the contact friction between the second connecting piece 302 and the cleaning assembly mounting cavity 260 can also be reduced, and the smoothness of the movement of the second connecting piece 302 can be improved.

[0350] When the second connecting piece 302 slides relative to the first connecting piece 301, the second connecting piece 302 can be manually pushed to slide relative to the first connecting piece 301. Alternatively, a driving assembly can be additionally arranged between the first connecting piece 301 and the second connecting piece 302, and the second connecting piece 302 can be driven to slide relative to the first connecting piece 301 by the driving assembly. FIG. 94 andFIG. 97 A driving assembly 306 is arranged between the first connecting member 301 and the second connecting member 302, a fixed end of the driving assembly 306 is connected with the first connecting member 301, and a driving end of the driving assembly 306 is connected with the second connecting member 302. The driving assembly 306 operates to drive the second connecting member 302 to slide relative to the first connecting member 301. The driving assembly 306 can be any linear driving mechanism capable of realizing the sliding operation of the second connecting member 302 relative to the first connecting member 301, such as a motor and a gear-rack structure, a motor and a ball screw structure, a pneumatic cylinder or a hydraulic cylinder, a flexible pull rope structure, etc.

[0351] By arranging the driving assembly 306, the 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 the control accuracy can be improved. Meanwhile, since the driving assembly 306 is arranged to realize the automatic control of the sliding operation of the first connecting member 301, the manual operation space needs not to be reserved on the cleaning assembly 100, and thus the compactness of the internal structure of the cleaning assembly 100 can be improved.

[0352] Please refer to FIG. 99 , FIG. 110 and FIG. 113 Optionally, in an embodiment of the utility model, the driving assembly 306 includes a second driving member 3061, a gear transmission assembly 3062 and a gear-rack transmission assembly 3063, and 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, and the second driving member 3061 can be any mechanism capable of outputting rotary motion, such as a motor, a combination of a motor and a speed reducer, a hydraulic pump, etc. Optionally, in the embodiment, as shown in FIG. 111 , the second driving member 3061 is a motor. The first gear 30621 is connected with an output shaft of the second driving member 3061, the second gear 30622 is installed on one end of the transmission shaft 30631, and the second gear 30622 is engaged 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 arranged inside the sliding cavity 3051, and the third gear 30632 is coaxially arranged with the second gear 30622.

[0353] Please refer to FIG. 113 and FIG. 116The 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 length direction of the rack 30633 is consistent with the length direction of the second connecting member 302. In the height direction of the cleaning assembly 100, the rack 30633 is engaged with the third gear 30632 below. The rack 30633 can be integrally connected with the second connecting member 302, or can be a separate part fixedly connected to the second connecting member 302 by bolts or other fasteners. Alternatively, in the embodiment, please refer to FIG. 116 The rack 30633 is integrally formed on the second connecting member 302. This arrangement can save the assembly process of the rack 30633 on the second connecting member 302, and is conducive to improving the assembly efficiency of the cleaning assembly 100.

[0354] The second driving member 3061 drives the first gear 30621 to rotate, which in turn drives the second gear 30622 to rotate through engagement, and drives the transmission shaft 30631 to rotate. The transmission shaft 30631 drives the third gear 30632 to rotate, which is engaged with the rack 30633, thereby driving the rack 30633 to move horizontally along its 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.

[0355] It should be noted that in other embodiments, the rack 30633 can be installed on a side wall of the second connecting member 302 facing away from the cleaning mechanism 303, and the third gear 30632 can be arranged above the rack 30633 and engaged with the rack 30633. In this way, the horizontal movement of the rack and the sliding of the second connecting member 302 relative to the first connecting member 301 can be realized when the second driving member 3061 is operated.

[0356] The second driving member 3061 provides rotary 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 mode runs smoothly, which is conducive to improving the stability of the sliding process of the second connecting member 302. At the same time, since the gear-rack transmission has high transmission efficiency and transmission accuracy, it is conducive to reducing power loss during transmission and improving the control accuracy of the sliding speed and operating position of the second connecting member 302.

Specifically, please refer to FIG. 109 and FIG. 111 The first connecting piece 301 is provided with a containing cavity 3012 on one side in the width direction of the sliding cavity 3051, and the containing cavity 3012 is in communication with the sliding cavity 3051. The second driving piece 3061 is arranged in the containing cavity 3012. Please refer to FIG. 94 The opening position of the containing cavity 3012 can also be provided with a protective cover 309, which is detachably connected to the first connecting piece 301. The protective cover 309 can protect the second driving piece 3061 in the containing cavity 3012, so as to reduce the probability of damage caused by collision during use of the second driving piece 3061. As shown in FIG. 111 The second driving piece 3061 is installed along the length direction of the first connecting piece 301, so that the output shaft of the second driving piece 3061 is vertically arranged with the transmission shaft 30631, and the meshing between the first gear 30621 and the second gear 30622 is realized.

[0358] By arranging the first gear 30621 and the second gear 30622 as bevel gear structures, the output shaft of the second driving piece 3061 can be vertically arranged with the transmission shaft 30631. This structure is more convenient for arranging the second driving piece 3061 outside the sliding cavity 3051, reduces the probability of interference between the installation position of the second driving piece 3061 and the sliding cavity 3051, and is also conducive to reducing the width size of the first connecting piece 301 and improving the compactness of the structure design.

[0359] In order to facilitate the installation of the transmission shaft 30631 on the first connecting piece 301, optionally, in an embodiment of the utility model, please refer to FIG. 109 and FIG. 111 One side of the first connecting piece 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 mounted in the mounting shaft hole 3013, and the other end of the transmission shaft 30631 is clamped and connected with the clamping interface 3014. Along the width direction of the first connecting piece 301, the mounting shaft hole 3013 can be arranged on the side of the first connecting piece 301 away from the second driving piece 3061, or on the side of the first connecting piece 301 close to the second driving piece 3061. Optionally, in this embodiment, along the width direction of the first connecting piece 301, the mounting shaft hole 3013 is arranged on the side of the first connecting piece 301 away from the second driving piece 3061. Specifically, it is arranged on the wall body away from the second driving piece 3061 on the side of the sliding cavity 3051. The clamping interface 3014 is arranged on the side of the first connecting piece 301 close to the second driving piece 3061, i.e. on the wall body away from the sliding cavity 3051 on the side of the containing cavity 3012.

[0360] The transmission shaft 30631 and the mounting shaft hole 3013 can be rotationally connected through shaft hole fitting or through a rotary bearing. Specifically, in the embodiment, as shown in FIG. 111 , an eighth rotary bearing 307 is arranged in the mounting shaft hole 3013, and the end of the transmission shaft 30631 away from the second driving member 3061 is connected to the eighth rotary bearing 307, thereby realizing the rotational connection between the transmission shaft 30631 and the mounting shaft hole 3013.

[0361] The clamping interface 3014 can be a U-shaped clamping interface, a semi-cylindrical clamping interface, or the like, which is matched with the shaft diameter of the transmission shaft 30631. In order to facilitate the clamping between the transmission shaft 30631 and the clamping interface 3014 and reduce the opening depth of the clamping interface 3014, as shown in FIG. 109 and FIG. 111 , the clamping interface 3014 is a semi-cylindrical clamping interface structure with an upward opening.

[0362] As shown in FIG. 154 , the shroud 309 is provided with a clamping opening 3091 corresponding to the clamping interface 3014. After the shroud 309 is installed above the accommodating cavity 3012, the clamping opening 3091 is clamped above the transmission shaft 30631 and cooperates with the clamping interface 3091 to limit the installation position of the transmission shaft 30631 in the radial direction at the clamping interface 3014, thereby improving the transmission accuracy of the transmission shaft 30631.

[0363] Since one end of the transmission shaft 30631 is clamped and connected through the clamping interface 3014, and the other end is rotationally connected to the mounting shaft hole 3013, during assembly, the one end of the transmission shaft 30631 can be clamped into the clamping 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 installation, the gear mounted on the transmission shaft 30631 does not need to be removed, so the gear can be installed on the transmission shaft 30631 in advance, thereby improving the installation efficiency of the driving assembly 306. At the same time, the clamping structure can facilitate the disassembly and assembly of the transmission shaft 30631 and the first connecting member 301, thereby facilitating the disassembly and assembly.

[0364] In order to further simplify the assembly process of the driving assembly 306 and improve the assembly efficiency, as shown in FIG. 111 and FIG. 117The second gear 30622 and the third gear 30632 are in an integral structure. The second gear 30622 and the third gear 30632 can be in the integral structure by being formed by casting or by being connected by welding. By setting the second gear 30622 and the third gear 30632 as an integral structure, the number of parts and the assembly steps in the assembly process can be reduced, the assembly process is simplified, and the overall assembly efficiency of the driving assembly 306 can be improved.

[0365] Optionally, in an embodiment of the utility model, please refer to FIG. 100 、 FIG. 101 and FIG. 109 , the first connecting piece 301 and the second connecting piece 302 are provided with a first position detection assembly 308, and the first position detection assembly 308 is used for detecting whether the second connecting piece 302 is located at the first sliding position or the second sliding position. As shown in FIG. 98 , when the second connecting piece 302 is located at the first sliding position, the cleaning mechanism 303 is in the lifting position, that is, the cleaning piece 110 is separated from the ground. As shown in FIG. 100 , when the second connecting piece 302 is located at the second sliding position, the cleaning mechanism 303 is in the mopping position, that is, the cleaning piece 110 is in contact with the ground to perform normal cleaning work. The first position detection assembly 308 is electrically connected with the second driving piece 3061. The first position detection assembly 308 comprises a first detection switch 3081 and a first stop block 3082, one of the first detection switch 3081 and the first stop block 3082 is arranged on the first connecting piece 301, and the other is arranged on the second connecting piece 302. Optionally, in the embodiment, the first stop block 3082 is arranged on the second connecting piece 302, and the first detection switch 3081 is arranged on the first connecting piece 301. Since the first connecting piece 301 is a fixed part, the wiring of the first detection switch 3081 can be facilitated in this way. The first detection switch 3081 can be a mechanical position detection switch, a photoelectric position detection switch, a Hall sensor detection switch or any structure that can meet the position detection requirements. In the embodiment, the first detection switch 3081 is a photoelectric detection switch. Since the photoelectric detection switch has the advantages of strong anti-interference ability, fast response speed, high reliability and the like, better position detection accuracy and detection stability can be obtained.

[0366] The number of the first detection switch 3081 and the first stop block 3082 is not limited, and in the embodiment, please refer to FIG. 100 、 FIG. 101 、 FIG. 102 and FIG. 109A first detection switch 3081 is provided on the first connecting member 301. Two first stops 3082 are provided on the second connecting member 302, and the two first stops 3082 are spaced apart along the length of the second connecting member 302. For ease of description, the two first stops 3082 are labeled as stop one 30821 and stop two 30822, respectively. FIG. 98 As shown, when the first connector 301 slides relative to the second connector 302, when the first connector 301 is at one end of the sliding direction, the stop block 30821 triggers the first detection switch 3081, generating a first positioning electrical signal. The first positioning electrical signal corresponds to the first sliding position of the second connector 302. FIG. 100 As shown, when the first connector 301 is at the other end of the sliding direction, the second stop 30822 triggers the first detection switch 3081, generating a second positioning electrical signal. The second positioning electrical signal corresponds to the second sliding position of the second connector 302. The first and second positioning electrical signals are electrically connected to the second drive unit 3061 through the control system on the cleaning device 1000. The second drive unit 3061 can control the first and second sliding positions of the second connector 302 according to the first and second positioning electrical signals, thereby realizing the automatic switching of the cleaning mechanism 303 between the rising position and the mopping position.

[0367] In other embodiments, two first detection switches 3081 and one first stop block 3082 may be provided. The first detection switches 3081 are spaced apart along the length of the first connector 301. When the first connector 301 is located at one end in the sliding direction, the first stop block 3082 triggers one of the first detection switches 3081 to generate a first positioning signal. When the first connector 301 is located at the other end in the sliding direction, the first stop block 3082 triggers the other first detection switch 3081 to generate a second positioning signal.

[0368] By setting the first positioning detection component 308, the first positioning detection component 308 can automatically trigger the generation of a positioning electrical signal, reducing manual intervention and thus improving the timeliness and accuracy of the sliding process control of the first connector 301. At the same time, since the first positioning detection component 308 can accurately detect the position of the second connector 302, it can ensure that it can accurately reach the first sliding position and the second sliding position during the sliding process.

[0369] Optionally, in an embodiment, the cleaning mechanism 303, the first connecting piece 301 and the second connecting piece 302 are detachably connected. There are various ways of detachable connection, in an embodiment, the first connecting piece 301 is provided with a sliding groove, and part of the structure on the cleaning mechanism 303 penetrates through the sliding groove and is connected by clamping connection with the second connecting piece 302 through a clamping structure. Exemplarily, the second connecting piece 302 is provided with an elastic clamping jaw, and a clamping slot is formed at the corresponding position of the cleaning mechanism 303, when the cleaning mechanism 303, the second connecting piece 302 and the first connecting piece 301 need to be assembled, the elastic clamping jaw is clamped into the clamping slot to realize clamping connection; when the cleaning mechanism 303, the second connecting piece 302 and the first connecting piece 301 need to be disassembled, the elastic clamping jaw is pulled out of the clamping slot, and the connection relationship between the cleaning mechanism 303, the second connecting piece 302 and the first connecting piece 301 is released. In another embodiment, the first connecting piece 301 is provided with a sliding groove, and part of the structure on the cleaning mechanism 303 penetrates through the sliding groove and is connected with the cleaning mechanism 303 through other stop pieces. Exemplarily, the stop piece can be a long strip block structure, the stop piece is arranged on the side of the second connecting piece 302 away from the cleaning mechanism 303, the stop piece is threadedly connected to the cleaning mechanism 303 through bolts or other fasteners, and the stop piece and the second connecting piece 302 are connected in abutment in the upward and downward directions, thereby realizing the hoisting connection between the cleaning mechanism 303 and the second connecting piece 302. By disassembling the stop piece, the disassembly and assembly between the cleaning mechanism 303, the second connecting piece 302 and the first connecting piece 301 can be realized.

[0370] By adopting detachable connection between the cleaning mechanism 303, the first connecting piece 301 and the second connecting piece 302, when a part of the cleaning mechanism 303, the first connecting piece 301 and the second connecting piece 302 fails or needs to be cleaned, it can be individually disassembled, replaced or cleaned, thereby facilitating the replacement and maintenance of the cleaning mechanism, reducing the maintenance cost and prolonging the service life.

[0371] Optionally, in an embodiment of the utility model, the cleaning mechanism 303 is detachably connected with a pin shaft, and the pin shaft is arranged on the side of the second connecting piece 302 away from the cleaning mechanism 303. The gravity of the cleaning mechanism 303 acts on the pin shaft to press the pin shaft against the second connecting piece 302.

[0372] In this way, the gravity of the cleaning mechanism 303 acts on the pin shaft to press the pin shaft against the second connecting piece 302, and this design can effectively prevent the connection between the second connecting piece and the cleaning mechanism 303 from loosening. Compared with the traditional fixed connection mode, this press-fit detachable connection can better adapt to the vibration and impact that the cleaning assembly 100 may encounter during use, thereby improving the stability of the connection.

[0373] Optionally in an embodiment of the utility model, the cleaning mechanism 303 is provided with an extension 3011, the extension 3011 is sequentially penetrated through the first connecting piece 301 and the second connecting piece 302, the extension 3011 is provided with a pin shaft mounting hole 30111, and the pin shaft is detachably penetrated in the pin shaft mounting hole 30111.

[0374] By setting the pin shaft mounting hole 30111 on the extension 3011, the pin shaft is detachably penetrated in the pin shaft mounting hole 30111, and this detachable connection mode makes the installation and dismounting of the pin shaft more convenient, especially in narrow space, can better adapt to the limitation of operation space, improves the convenience of operation.

[0375] Optionally in an embodiment of the utility model, the second connecting piece 302 is provided with an inclined plane 30411, the outer circumferential surface of the pin shaft abuts against the inclined plane 30411 and slides along the inclined plane 30411 to drive the cleaning mechanism 303 to switch between the lifting position and the mopping position.

[0376] By setting the inclined plane 30411 and making the pin shaft abut against the inclined plane 30411, on the one hand, the abutment of the pin shaft and the inclined plane 30411 can realize the connection between the cleaning mechanism 303 and the second connecting piece 302, and ensure the stability and reliability of the connection. On the other hand, by sliding the pin shaft along the inclined plane 30411, the lifting of the cleaning mechanism 303 can also be realized, that is, the cleaning mechanism 303 can be between the lifting position and the mopping position.

[0377] Optionally in an embodiment of the utility model, the cleaning mechanism 303 is provided with an extension 3011, the extension 3011 is provided with a pin shaft mounting hole 30111, the side wall of the first connecting piece 301 is provided with a first butt joint hole 3018, the side wall of the second connecting piece 302 is provided with a second butt joint hole 3024, when the pin shaft is located at a specified position on the inclined plane 30411, the first butt joint hole 3018, the second butt joint hole 3024 and the pin shaft mounting hole 30111 are coaxially aligned and communicated with each other to realize the dismounting of the pin shaft along the axial direction of itself.

[0378] In the above embodiment, since the first butt joint hole 3018, the second butt joint hole 3024 and the pin shaft mounting hole 30111 are coaxially aligned, the dismounting of the pin shaft along the axial direction of itself can be realized, therefore, when the pin shaft needs to be dismounted, only needs to align the first butt joint hole 3018, the second butt joint hole 3024 and the pin shaft mounting hole 30111, the pin shaft can be quickly and accurately inserted or dismounted, without complex alignment operation. This design can significantly reduce the dismounting time and improve the installation and dismounting efficiency.

[0379] Optionally, in an embodiment of the utility model, when the pin shaft is located at the specified position on the inclined surface 30411, the cleaning mechanism 303 is located at the transition position between the rising position and the mopping position.

[0380] In this way, during the operation of the cleaning assembly 100, since the cleaning mechanism 303 stays at the mopping position and the rising position most of the time, the cleaning mechanism 303 stays at the transition position for a short time, so the pin shaft is almost not located at the specified position on the inclined surface 30411 for a long time. This design can effectively reduce the probability of the pin shaft being pulled out of the pin seat mounting hole 30111 during the operation, thereby improving the stability and reliability of the overall structure connection.

[0381] Optionally, in an embodiment of the utility model, the second connecting piece 302 is provided with a first through slot 3023, the extension direction of the first through slot 3023 is consistent with the sliding direction of the second connecting piece 302, and the extension part 3011 is slidably arranged in the first through slot 3023.

[0382] By arranging the first through slot 3023, the first through slot 3023 can play a guiding role in the sliding direction of the extension part 3011, ensuring that it moves in the predetermined direction during the sliding process, reducing the probability of shaking or deviation, and thereby facilitating the alignment between the first butt joint hole 3018, the second butt joint hole 3024 and the pin shaft mounting hole 30111, and further improving the disassembly and assembly efficiency of the pin shaft.

[0383] In the prior art, the cleaning part 110 on the cleaning device 1000 is usually fixedly arranged relative to the position of the machine body 200, and due to the limitation of the machine body 200 of the cleaning device 1000, the cleaning part 110 has a certain area limitation when performing the cleaning work, for example, the cleaning part 110 cannot clean the corners of the surface to be cleaned, which affects the cleaning effect.

[0384] In order to solve the above problems, please refer to FIG. 118 to FIG. 120 In some embodiments, the utility model also provides a cleaning assembly 100, which is provided with a translation mechanism 400, the translation mechanism 400 can drive the cleaning mechanism 303 to move horizontally relative to the machine body 200, so that the cleaning mechanism 303 has a retracted position or an expanded position, thereby improving the cleaning effect of the cleaning device 1000.

[0385] Please refer to FIG. 118 to FIG. 120 The cleaning assembly 100 comprises a first connecting piece 301, a second connecting piece 302 and a cleaning mechanism 303.

[0386] The first connecting piece 301 is detachably connected with the bottom of the machine body 200, and the detachable connection mode can refer to the related structure in the foregoing embodiments, which will not be described herein.

[0387] 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 utility model, please refer to FIG. 101 、 FIG. 105 、 FIG. 109 and FIG. 110 , a second guide assembly 305 for guiding the second connecting member 302 to slide along the first connecting member 301 is arranged between the first connecting member 301 and the second connecting member 302. The specific structure of the second guide assembly 305 can refer to the related description in the above embodiment, which will not be described in detail here.

[0388] Please refer to FIG. 96 and FIG. 119 , the cleaning mechanism 303 is movably installed on the first connecting member 301, and the cleaning mechanism 303 has an outwardly expanded position (as shown in FIG. 119 ) and an inwardly retracted position (as shown in FIG. 96 ) relative to the first connecting member 301. The specific structure of the cleaning mechanism 303 can refer to the related description of the cleaning mechanism 303 in the above embodiment, which will not be repeated here. As shown in FIG. 155 , when the cleaning mechanism 303 is in the outwardly expanded position, at least part of the edge of the cleaning member 110 is located outside the widest edge projection area of the body 200. As shown in FIG. 156 , when the cleaning mechanism 303 is in the inwardly retracted position, the edge of the cleaning member 110 is located within the widest edge projection area of the body 200.

[0389] Please refer to FIG. 118 to FIG. 120 , a translation mechanism 400 is arranged between the cleaning mechanism 303 and the second connecting member 302, and 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 outwardly expanded position or the inwardly retracted position. In order to facilitate description, when the cleaning mechanism 303 is in the inwardly retracted position, the sliding position of the second connecting member 302 relative to the first connecting member 301 is positioned as a third sliding position (as shown in FIG. 96 ), and when the cleaning mechanism 303 is in the outwardly expanded position, the sliding position of the second connecting member 302 relative to the first connecting member 301 is positioned as a fourth sliding position (as shown in FIG. 119 ).

[0390] For example, when the cleaning assembly 100 needs to clean the corner of the floor, the translation mechanism 400 drives the cleaning mechanism 303 to move from the inner retracted position to the outer expanded position, so that at least part of the edge of the cleaning member 110 is located outside the widest edge projection area of the main body 200, thereby completing the cleaning of the corner. For another example, when the cleaning assembly 100 needs to perform normal cleaning operation on the floor (without cleaning the corner), the translation mechanism 400 drives the cleaning mechanism 303 to move from the outer expanded position to the inner retracted position, so that the edge of the cleaning member 110 is located within the widest edge projection area of the main body 200, thereby completing the normal cleaning operation on the floor.

[0391] 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 the length direction of the cleaning mechanism 303, or move horizontally along the width direction of the cleaning mechanism 303. Alternatively, please refer to FIG. 118 and FIG. 119 In this embodiment, the cleaning mechanism 303 moves horizontally along the length direction of the cleaning mechanism 303 to switch between the inner retracted position and the outer expanded position. In this way, the cleaning mechanism 303 can switch between the inner retracted position and the outer expanded position with a smaller horizontal displacement, thereby effectively improving the switching efficiency and the space utilization of the bottom of the main body 200.

[0392] The translation mechanism 400 can be a sliding groove and sliding block structure. The sliding groove is arranged on the first connecting member 301, and the extension direction of the sliding groove is consistent with the horizontal moving direction of the cleaning mechanism 303. One end of the sliding block is connected with the cleaning mechanism 303, and the other end of the sliding block is connected with the second connecting member 302. When the second connecting member 302 slides relative to the first connecting member 301, the sliding block slides in the sliding groove, 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 sliding block structure. The guide rail is installed on the first connecting member 301, and the length direction of the guide rail is consistent with the horizontal moving direction of the cleaning mechanism 303. The cleaning mechanism 303 and the second connecting member 302 are both fixed on the sliding block, and the sliding block 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 sliding block slides along the guide rail, thereby driving the cleaning mechanism 303 to move horizontally relative to the first connecting member 301.

[0393] The cleaning assembly 100 is provided with the translation mechanism 400, when the second connecting piece 302 slides relative to the first connecting piece 301, the translation mechanism 400 can drive the cleaning mechanism 303 to move horizontally, so that the cleaning mechanism 303 is switched between the outward expansion position and the inward retraction position. In this way, when the cleaning is in normal cleaning operation (without cleaning the corners), the cleaning piece 110 can clean the surface to be cleaned only in the inward retraction position. In this way, the area of the cleaning piece 110 extending outside the machine body can be reduced, thereby reducing the probability of accidental damage of the cleaning mechanism 303 due to external force impact and friction, so it is more suitable for operation in complex environment, for example, the scene needs to be frequently moved or cleaned in narrow space. When the cleaning device 1000 needs to clean the corners of the surface to be cleaned, the cleaning piece 110 can be moved from the inward retraction position to the outward expansion position, so as to realize effective cleaning of the corner area of the cleaning device 1000, thereby improving the cleaning effect of the cleaning device 1000 on the corners.

[0394] Optionally, in an embodiment of the utility model, the outward expansion and inward retraction stroke range of the cleaning mechanism 303 is 40-50mm, that is, the horizontal stroke range of the cleaning mechanism 303 moving from the inward retraction position to the outward expansion position is 40-50mm. Preferably, the outward expansion and inward retraction stroke of the cleaning mechanism 303 is 46.5mm. Limiting the outward expansion and inward retraction stroke of the cleaning mechanism 303 to the range of 40-50mm can ensure that the cleaning assembly 100 can cover the predetermined corner cleaning area when it is in the outward expansion position, and can avoid the cleaning assembly 110 from being excessively retracted to cause insufficient cleaning range, thereby facilitating to ensure the consistency of the cleaning effect. At the same time, since too large stroke may cause overload of the translation mechanism (such as motor, air cylinder, etc.), shorten its service life, therefore, limiting the outward expansion and inward retraction stroke of the cleaning mechanism 303 to the range of 40-50mm can avoid too large stroke of the translation mechanism 400, thereby protecting the translation mechanism 400 and prolonging its service life.

[0395] Optionally, in an embodiment of the utility model, please refer to FIG. 155In the outwardly extending position of the cleaning mechanism 303, the outer edge of the cleaning mechanism 303 extends outwardly beyond the outer edge of the main body 200 by a dimension D of 7-9mm, for example, 7mm, 8mm or 9mm, and preferably 8.75mm, in the moving direction of the cleaning mechanism 303. The outer edge of the cleaning member 110 mounted on the cleaning mechanism 303 extends outwardly beyond the outer edge of the main body 200 by a dimension C of 2-4mm, for example, 2mm, 3mm or 4mm, and preferably 3mm. By limiting the dimension D of the outward extension of the outer edge of the cleaning mechanism 303 to 7-9mm, the outwardly extending position of the cleaning mechanism 303 can cover a larger cleaning range, and the cleaning member 110 can reach a farther position, especially a position close to a wall or a corner, and the like, which is difficult to clean. Meanwhile, the dimension D is limited to 7-9mm, so that the load on the translation mechanism 400 can be prevented from being too large due to the excessive extension. By limiting the dimension C of the outward extension of the outer edge of the cleaning member 110 to 2-4mm, the cleaning member 110 can effectively cover the corner area outside the main body 200, and the area of the blind area of the cleaning operation can be reduced, so that the cleaning effect of the corner position can be improved.

[0396] Optionally, in an embodiment of the present application, referring to FIG. 105 、 FIG. 109 、 FIG. 118 and FIG. 120 , the translation mechanism 400 comprises a second through slot 3053 and a connecting assembly 320. The second through slot 3053 is arranged on the first connecting member 301, and the cleaning mechanism 303 is connected to the second connecting member 302 through the connecting assembly 320. The connecting assembly 320 is at least partially slidably connected to the second through slot 3053. The second through slot 3053 extends along the length direction of the cleaning mechanism 303. There can be one, two or more second through slots 3053. Optionally, in the present embodiment, referring to FIG. 109 and FIG. 111 , two second through slots 3053 are arranged side by side along the width direction of the first connecting member 301. One part of the connecting assembly 320 is slidably connected to one of the two second through slots 3053, and the other part of the connecting assembly 320 is slidably connected to the other second through slot 3053. In this way, the stability of the movement of the second connecting member 302 driven by the translation mechanism 400 can be improved. There can be one or more connecting assemblies 320. Optionally, referring to FIG. 118 , in the present embodiment, two connecting assemblies 320 are arranged along the length direction of the cleaning mechanism 303. In this way, two lifting points in the length direction of the cleaning mechanism 303 can be formed, so that the weight of the cleaning mechanism 303 can be effectively dispersed, and the inclination or shaking of the cleaning mechanism 303 due to the single-point force can be avoided, which is beneficial to further improve the stability of the translation movement of the cleaning mechanism 303.

[0397] In the embodiment, the specific structure of the connecting assembly 320 is not limited, for example, the connecting assembly 320 can be a combined structure of a connecting block and a fastener, one end of the connecting block is connected with the cleaning mechanism 303, the other end of the connecting block penetrates through the second through slot 3053, and then the connecting block is fixedly connected with the bottom surface of the second connecting piece 302 through the fastener (such as a bolt, a screw or the like). The connecting assembly 320 can also be a combination of a connecting block and a clamping structure, one end of the connecting block is connected with the cleaning mechanism 303, and the other end of the connecting block is clamped and connected with the clamping structure arranged on the second connecting piece 302, so as to realize the connection between the second connecting piece 302 and the cleaning mechanism 303.

[0398] In the embodiment, through the cooperation of the second through slot 3053 and the connecting assembly 320, when the second connecting piece 302 slides relative to the first connecting piece 301, the connecting assembly 320 can drive the cleaning mechanism 303 to move horizontally, so as to realize the switching between the inner retracted position and the outer expanded position. The structure design can reduce the complex transmission components in the traditional translation mechanism 400 and simplify the overall mechanical structure. At the same time, since the number of parts is small and the structure is simplified, the manufacturing cost of the cleaning equipment 1000 can be reduced.

[0399] Optionally, in an embodiment of the utility model, referring to FIG. 120 to FIG. 123 , the connecting assembly 320 comprises a connecting end 3015, an abutting portion 3042 and a clamping groove 321. The abutting portion 3042 is arranged on the side of the second connecting piece 302 away from the cleaning mechanism 303, the clamping groove 321 is arranged on the side of the second connecting piece 302 away from the cleaning mechanism 303, the abutting portion 3042 is clamped in the clamping groove 321 and can form a limit in the sliding direction of the second connecting piece 302. Referring to FIG. 120 and FIG. 123 , one end of the connecting end 3015 is connected with the side of the cleaning mechanism 303 facing the first connecting piece 301, and the other end of the connecting end 3015 penetrates through the second through slot 3053 and the bottom wall of the second connecting piece 302 from bottom to top in the height direction of the cleaning mechanism 303 and is connected with the abutting portion 3042. The clamping groove 321 is supported below the abutting portion 3042, and the abutting portion 3042 is pressed against the bottom wall of the clamping groove 321 by the gravity of the cleaning mechanism 303.

[0400] For the convenience of description, the specific structure of any one end of the connecting assembly 320 is taken as an example for expansion description. Specifically, referring to FIG. 120 to FIG. 122At one end of the length direction of the second connecting piece 302, the bottom wall of the second connecting piece 302 is provided with two first through grooves 3023. Along the width direction of the second connecting piece 302, the two first through grooves 3023 are respectively arranged on both sides of the clamping groove 321. The shape of the first through groove 3023 is not limited, as long as the extension part 3011 can pass through. Please refer to FIG. 120 and FIG. 123 The connecting end 3015 includes two extension parts 3011, and each extension part 3011 corresponds to one first through groove 3023. One end of the extension part 3011 is connected with the cleaning mechanism 303, and the other end of the extension part 3011 is arranged in the first through groove 3023 and at least partially extends to the side of the second connecting piece 302 away from the cleaning mechanism 303. The two ends of the abutting part 3042 are respectively connected with the two extension parts 3011, so as to realize the clamping connection between the abutting part 3042 and the clamping groove 321, thereby realizing the connection between the second connecting piece 302 and the cleaning mechanism 303. By making the abutting part 3042 abut and press against the bottom wall of the clamping groove 321, the connecting assembly 320 can form a relatively stable connection relationship with the second connecting piece 302 under the gravity of the cleaning mechanism 303. This connection relationship not only can reduce the risk of the cleaning mechanism 303 falling due to mechanical looseness, but also can improve the operation reliability of the cleaning equipment 1000.

[0401] In order to reduce the installation space occupied by the connecting assembly 320 in the height direction of the cleaning equipment 1000, optionally, please refer to FIG. 120 to FIG. 122 In an embodiment of the utility model, the second connecting piece 302 includes a concave cavity 3021, the concave cavity 3021 is recessed towards the side away from the cleaning mechanism 303, and the bottom wall of the concave cavity 3021 is in sliding abutment with the bottom wall of the sliding cavity 3051. The clamping groove 321 is arranged in the concave cavity 3021. The second through groove 3053 is arranged on the bottom wall of the concave cavity 3021, and the extension part 3011 is at least partially located in the concave cavity 3021 after penetrating through the second through groove 3053.

[0402] The arrangement of the concave cavity 3021 enables at least part of the extension part 3011 and the abutting part 3042 to be accommodated inside the second connecting piece 302, so that the installation space occupied by the connecting assembly 320 in the height direction of the cleaning equipment 1000 can be reduced, the structure of the entire cleaning equipment 1000 is more compact, and the overall height size can be reduced.

[0403] The forming mode of the clamping groove 321 in the concave cavity 3021 is not limited, for example, two protrusions can be arranged on the bottom wall of the concave cavity 3021, and the clamping groove 321 is formed by surrounding the two protrusions and the bottom wall of the concave cavity 3021. It can also be that a clamping groove structure is separately connected on the bottom wall of the concave cavity 3021. Optionally, in an embodiment of the utility model, please refer to FIG. 120 to FIG. 122The inner part of the cavity 3021 is provided with a protruding structure 3022 connected to one side wall of the cavity 3021 in the length direction and the bottom wall of the cavity 3021, and the protruding structure 3022, the bottom wall of the cavity 3021 and the side wall of the cavity 3021 form a clamping groove 321. It should be noted that the length direction of the cavity 3021 is consistent with the length direction of the second connecting piece 302. Specifically, please refer to FIG. 122 In the length direction of the cavity 3021, the wall body on the side of the 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 cavity 3021 and the side wall of the cavity 3021 form a clamping groove 321, which means that the protruding structure 3022, the bottom wall of the cavity 3021 and the first side wall 30211 form a clamping groove 321. The protruding structure 3022 can be a cuboid protrusion, a wedge-shaped protrusion, a trapezoidal protrusion or the like, and the present embodiment does not limit the same.

[0404] Since the protruding structure 3022 is arranged in the cavity 3021, and the protruding structure 3022 is connected to the side wall and the bottom wall of the cavity 3021, the arrangement can improve the connection support strength of the side wall of the clamping groove 321, reduce the probability of deformation of the clamping groove 321 during long-term work, and cause displacement of the abutting part 3042 in the clamping groove 321, thereby improving the switching accuracy of the cleaning mechanism 303 between the inner retracted position and the outer expanded position.

[0405] Optionally, in an embodiment of the utility model, please refer to FIG. 120 to FIG. 122 The protruding structure 3022 includes an inclined surface 30411. In the depth direction of the cavity 3021, the inclined surface 30411 is inclined from the bottom wall of the cavity 3021 to the opening side of the cavity 3021. One end of the inclined surface 30411 is connected to the bottom wall of the cavity 3021. For the convenience of description, the bottom wall of the 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 to the opening side of the cavity 3021. In the width direction of the cavity 3021, two first through grooves 3023 are arranged on the two sides of the inclined surface 30411, and the first through groove 3023 is a long slot structure extending in the length direction of the cavity 3021, and the extension part 3011 is slidably installed in the first through groove 3023. When the cleaning mechanism 303 is in the inner retracted position, under the sliding action of the second connecting piece 302, the abutting part 3042 can slide along the inclined surface 30411 to drive the cleaning mechanism 303 to make lifting movement relative to the first connecting piece 301.

[0406] The abutting part 3042 can be an inclined block, an arc-shaped block, a pin shaft or the like, which can slide along the inclined surface 30411. Optionally, in the present embodiment, please refer to FIG. 120The supporting part 3042 is a pin, and each of the two extensions 3011 is provided with a pin mounting hole 30111. The two ends of the pin are respectively installed in the corresponding pin mounting holes 30111. This effectively reduces the frictional force generated when the supporting part 3042 and the inclined surface 30411 move relative to each other, facilitating the sliding of the supporting part 3042 along the inclined surface 30411. It should be noted that the pin and the pin mounting hole 30111 can be either a rotatable connection or a fixed connection; this embodiment is not limited to either.

[0407] For ease 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, such as... FIG. 96 As indicated by arrow S1. The sliding direction of the second connector 302 when the cleaning mechanism 303 is moved from the expanded position to the retracted position is defined as the second direction, as shown in the image. FIG. 119 The direction of arrow S2 is shown in the middle.

[0408] Please see FIG. 118 to FIG. 120 During the process of the cleaning mechanism 303 moving from the outward expansion position to the inward retraction position, that is, when the second connecting member 302 slides along the second direction, firstly, as FIG. 120 and FIG. 126 As shown, in the initial state, one end of the extension 3011 stops at the end of the second through groove 3053 away from the drive structure 160, and the holding part 3042 engages with the snap-fit ​​groove 321. When the second connector 302 slides along the second direction, it drives the cleaning mechanism 303 to move horizontally synchronously until the cleaning mechanism 303 moves from... FIG. 118 The outward expansion position shown has been moved to FIG. 124 The inward position is shown. In FIG. 124 At the recessed position shown, one end of the second through groove 3053 stops along the second direction on one side of the extension 3011, as shown. FIG. 127 As shown, this restricts further horizontal movement of the cleaning mechanism 303 along 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.

[0409] Please see FIG. 96 and FIG. 124 After the cleaning mechanism 303 retracts into place, the second connector 302 continues to slide along the second direction. Under the action of the second through groove 3053, the extension 3011 no longer moves relative to the first connector 301. Please refer to [link / reference]. FIG. 120 At this point, the pin begins to slide upward along the inclined surface 30411, and the extension 3011 slides relative to the second connector 302 within the first through groove 3023, thereby driving the cleaning mechanism 303 to move upward relative to the first connector 301, causing the pin to move from... FIG. 120 Move to the position shown FIG. 98the cleaning mechanism 303 is converted from the mopping position shown in FIG. 96 to the raised position shown in FIG. 95 . Please refer to FIG. 98 , when the other end of the first through slot 3023 is stopped at the other side of the extension 3011 in the second direction, it indicates that the cleaning mechanism 303 has been raised in place, at this time the second connecting piece 302 stops sliding, and the cleaning mechanism 303 stops rising. At this time, the cleaning mechanism 303 is in the retracted raised position shown in FIG. 95 .

[0410] When the cleaning mechanism 303 needs to perform cleaning work again, that is, it needs to switch from the raised position to the mopping position, at this time, slide the second connecting piece 302 in the first direction shown in FIG. 95 . Since there is no stop action between the first through slot 3023 and the extension 3011 in the first direction, as shown in FIG. 98 , when the second connecting piece 302 slides, it will not drive the extension 3011 to move horizontally in the first direction. At this time, under the action of the gravity of the cleaning mechanism 303, the pin shaft begins to slide downward along the inclined surface 30411, and the extension 3011 slides in the opposite direction in the first through slot 3023 relative to the second connecting piece 302, thereby driving the cleaning mechanism 303 to move downward relative to the first connecting piece 301, realizing the lowering action of the cleaning mechanism 303, as shown in FIG. 100 . At this time, the pin shaft is again engaged with the clamping groove 321, that is, the pin shaft is in contact with the first plane 30412, and the cleaning mechanism 303 is switched to the mopping position again, and the second connecting piece 302 stops sliding, and the cleaning mechanism 303 stops descending. The cleaning mechanism is in the retracted mopping position shown in FIG. 96 .

[0411] When the cleaning mechanism needs to be expanded to perform corner work, at this time the cleaning mechanism 303 needs to move from the retracted position to the expanded position, that is, the second connecting piece 302 needs to slide from the position shown in FIG. 96 to the position shown in FIG. 119 . First, as shown in FIG. 118 and FIG. 127 , in the initial state, one end of the extension 3011 is stopped at the end of the second through slot 3053 away from the driving structure 160, and the abutting portion 3042 is engaged with the clamping groove 321. When the second connecting piece 302 slides in the first direction, it drives the cleaning mechanism 303 to move horizontally synchronously until the cleaning mechanism 303 moves from the retracted position shown in FIG. 96 and FIG. 99 to the expanded position shown in FIG. 119 and FIG. 124 . In the expanded position shown in FIG. 124 , at this time, one end of the second through slot 3053 is stopped at one side of the extension 3011 in the second direction, as shown inFIG. 126 The inclined surface 30411 is arranged to limit the further horizontal movement of the cleaning mechanism 303 in the first direction. In this state, the cleaning mechanism 303 is in the outwardly expanded mopping position.

[0412] By arranging the inclined surface 30411, when the cleaning mechanism 303 is in the inwardly retracted position, the pin shaft can slide along the inclined surface 30411 to drive the cleaning mechanism 303 to perform the lifting movement relative to the first connecting member 301. In this way, by sliding the second connecting member 302, not only can the switching between the outwardly expanded position and the inwardly retracted position of the cleaning mechanism 303 be realized, but also the lifting movement of the cleaning mechanism 303 relative to the first connecting member 301 can be realized, and the switching between the mopping position and the raised position can be realized. In this way, the cleaning operation in various application scenarios can be better satisfied. For example, during the cleaning operation, when the machine body 200 passes through a carpet, the cleaning mechanism 303 can be switched to the raised position to avoid wetting the carpet; or in the scenarios of obstacle crossing, base station returning, etc., the cleaning mechanism 303 can also be switched to the raised position to avoid that the cleaning mechanism 303 is stuck by the obstacle and separated from the machine body 200.

[0413] Optionally, in an embodiment of the present application, referring to FIG. 120 to FIG. 122 , the protruding structure 3022 further comprises a second plane 30413, which is arranged on the side of the inclined surface 30411 away from the first plane 30412. As FIG. 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 surface 30411 away from the first plane 30412, and the other end of the second plane 30413 is connected to the side wall body 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 FIG. 98 shown, when the cleaning mechanism 303 is in the raised position, the abutting part 3042 abuts against the second plane 30413. In this way, when the cleaning mechanism 303 is in the raised position, the abutting part 3042 can realize the self-locking between the abutting part 3042 and the second plane 30413 only by the gravity of the cleaning mechanism 303 without the need for additional braking force. Therefore, not only can the overall structure be simplified, but also the stability of the cleaning mechanism 303 in the raised position can be ensured, and accidental movement or position change caused by external force or vibration can be prevented.

[0414] When the second connecting piece 302 slides relative to the first connecting piece 301, the sliding of the second connecting piece 302 relative to the first connecting piece 301 can be manually pushed by the second connecting piece 302. Alternatively, a driving assembly 306 can be additionally arranged between the first connecting piece 301 and the second connecting piece 302, and the second connecting piece 302 is driven to slide relative to the first connecting piece 301 by the driving assembly 306. Optionally, in an embodiment of the utility model, please refer to FIG. 97 and FIG. 99 A driving assembly 306 is arranged between the first connecting piece 301 and the second connecting piece 302, the fixed end of the driving assembly 306 is connected with the first connecting piece 301, and the driving end of the driving assembly 306 is connected with the second connecting piece 302. The driving assembly 306 drives the second connecting piece 302 to slide relative to the first connecting piece 301. The driving assembly 306 can be any linear driving mechanism that can realize the sliding of the second connecting piece 302 relative to the first connecting piece 301, such as a gear and rack structure, a motor and a ball screw structure, a pneumatic cylinder or a hydraulic cylinder.

[0415] By arranging the driving assembly 306, the automatic control of the sliding operation of the second connecting piece 302 relative to the first connecting piece 301 can be realized, and the operation efficiency and control accuracy can be improved. At the same time, since the driving assembly 306 is arranged to realize the automatic control of the sliding operation of the first connecting piece 301, the manual operation space needs not to be reserved on the cleaning assembly 100, and the compactness of the internal structure of the cleaning assembly 100 can be improved.

[0416] It should be noted that the driving assembly 306 in the embodiment can adopt the structure of the driving assembly 306 in the above-mentioned embodiment, and thus has the beneficial effects of the driving assembly 306 in the above-mentioned embodiment. Of course, it can be understood that in the embodiment, other driving assemblies can also be used to drive the sliding of the second connecting piece 302, as long as the sliding performance requirements of the second connecting piece 302 are met.

[0417] Optionally, in an embodiment of the utility model, please refer to FIG. 98 and FIG. 100 A first position detection assembly 308 is arranged between the first connecting piece 301 and the second connecting piece 302, and the first position detection assembly 308 is used to detect whether the second connecting piece 302 is located at the first sliding position or the second sliding position. The first position detection assembly 308 is electrically connected with the second driving piece 3061. The specific structure and arrangement position of the first position detection assembly 308 can refer to the related structure description in the above-mentioned embodiment, which will not be described here.

[0418] On the basis of arranging the first position detection assembly 308 between the first connecting piece 301 and the second connecting piece 302, optionally, in an embodiment of the utility model, please refer to 124 andFIG. 125 The second-to-position detection assembly 310 is arranged between the first connecting member 301 and the second connecting member 302, and is used to detect whether the second connecting member 302 is located at the third sliding position or the fourth sliding position. FIG. 128 When the second connecting member 302 is located at the third sliding position, the cleaning mechanism 303 is in the retracted position. Figure 129 When the second connecting member 302 is located at the fourth sliding position, the cleaning mechanism 303 is in the expanded position. Figure 130 Figure 131 The second-to-position detection assembly 310 is electrically connected with the second driving member 3061. As shown in Figure 125 The second-to-position detection assembly 310 comprises a second detection switch 311 and a second stopper 312, one of which is arranged on the first connecting member 301, and the other is arranged on the second connecting member 302. In this embodiment, the second stopper 312 is arranged on the second connecting member 302, and the second detection switch 311 is arranged on the first connecting member 301. Since the first connecting member 301 is a fixed member, the arrangement can facilitate the wiring of the second detection switch 311. The second detection switch 311 can be any structure that can meet the requirements of to-position detection, such as a mechanical to-position detection switch, an optoelectronic to-position 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, high reliability, etc., it can obtain better to-position detection accuracy and detection stability.

[0419] The number of the second detection switch 311 and the second stopper 312 is not limited. In this embodiment, as shown in Figure 125 One second detection switch 311 is arranged on the first connecting member 301. Two second stoppers 312 are arranged on the second connecting member 302, and the two second stoppers 312 are arranged at intervals along the length direction of the second connecting member 302. For the convenience of description, the two second stoppers 312 are marked as stopper three 3121 and stopper four 3122 respectively. Figure 129 ​As shown, when the second connecting member 302 is located at one end of the sliding direction, the third stopper 3121 triggers the second detection switch 311 to generate a third arrival signal, and the third arrival signal corresponds to a third sliding position of the second connecting member 302. When the second connecting member 302 is located at the other end of the sliding direction, the fourth stopper 3122 triggers the second detection switch 311 to generate a fourth arrival signal, and the fourth arrival signal corresponds to a fourth sliding position of the second connecting member 302. The third arrival signal and the fourth arrival signal are electrically connected to the second driving member 3061 through the 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 arrival signal and the fourth arrival signal, so as to realize the automatic switching of the cleaning mechanism between the inner retracted position and the outer expanded position.

[0420] In other embodiments, two second detection switches 311 and one second stopper 312 can also be provided. The two second detection switches 311 are arranged along the length direction of the first connecting member 301. When the first connecting member 301 is located at one end of the sliding direction, the second stopper 312 triggers one of the two second detection switches 311 to generate a third arrival signal. When the first connecting member 301 is located at the other end of the sliding direction, the second stopper 312 triggers the other second detection switch 311 to generate a fourth arrival signal.

[0421] By providing the second arrival detection assembly 310, the second arrival detection assembly 310 can automatically trigger the generation of the arrival signal, reduce manual intervention, and thus improve the timeliness and accuracy of the control of the sliding process of the second connecting member 302. At the same time, since the second arrival detection assembly 310 can accurately detect whether the second connecting member 302 is at the third sliding position or the fourth sliding position, the repeated arrival accuracy of the cleaning mechanism 303 when switching between the inner retracted position and the outer expanded position can be ensured.

[0422] It should be noted that, please refer to Figure 132 When the cleaning mechanism 303 is in the inner retracted and ascending position, the first stopper 30821 triggers the first detection switch 3081 to generate a first arrival signal at this time, and the second detection switch remains in a non-triggering state. Please refer to Figure 129 When the cleaning mechanism 303 is in the inner retracted and mopping position, the second stopper 30822 triggers the first detection switch 3081 to generate a second arrival signal at this time. At the same time, the third stopper 3121 triggers the second detection switch 311 to generate a third arrival signal. Please refer to Figure 131 When the cleaning mechanism 303 is in the outer expanded position, the first detection switch remains in a non-triggering state at this time, and the fourth stopper 3122 triggers the second detection switch 311 to generate a fourth arrival signal.

[0423] Referring to Figure 133 and Figure 134 In an embodiment of the present application, the body 200 of the cleaning device 1000 is further provided with a clean water tank 500 and a sewage tank 600. The clean water tank 500 is used to supplement clean water to the cleaning member 110, so that the cleaning member 110 can maintain a wet state during the cleaning operation, and realize wet mopping of the surface to be cleaned, thereby 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.

[0424] Referring to Figure 135 and Figure 136 The shell 180 of the cleaning assembly 100 is provided with a clean water outlet 501, a sewage suction port 502 and a sewage collection cavity 503, and the sewage suction port 502 communicates with the sewage collection cavity 503. The sewage in the sewage collection cavity 503 is discharged through the sewage suction port 502. The clean water outlet 501 is provided with a plurality of clean water outlets 501, and the plurality of clean water outlets 501 are arranged along the length direction of the shell 180. In this way, the uniformity of the water supplementing effect of the cleaning member 110 can be improved.

[0425] Referring to Figure 135 and Figure 137 The shell 180 is further provided with a clean water delivery pipe 504 and a sewage suction port outlet 5021, and the sewage suction port outlet 5021 communicates with the sewage suction port 502. The clean water delivery pipe 504 communicates the clean water tank 500 and the clean water outlet 501. The clean water tank 500 delivers clean water to the clean water outlet 501 through the clean water delivery pipe 504, and the clean water is sprayed to the surface of the cleaning member 110 through the clean water outlet 501, so that the cleaning member 110 is soaked in clean water.

[0426] Optionally, referring to Figure 137 In an embodiment of the present application, the clean water delivery pipe 504 is at least partially a heat conducting pipe section 5041, and the first driving member 161 is an electric motor. The heat conducting pipe section 5041 is wound on the first driving member 161 and can conduct heat with the first driving member 161. In this way, the heat generated by the first driving member 161 during operation can be conducted to the heat conducting pipe section 5041, so as to heat the clean water in the clean water delivery pipe 504, thereby increasing the temperature of the clean water supplemented on the cleaning member 110, and further improving the cleaning effect of the cleaning member 110. At the same time, the heat generated by the first driving member 161 during operation can also be taken away by the continuous flow of clean water in the clean water delivery pipe 504, thereby cooling the first driving member 161.

[0427] Optionally, in an embodiment, referring to Figure 137The clean water delivery pipe 504 further comprises a transition pipe section 5042. The housing 180 further comprises a clean water inlet 505 arranged on a side of the housing 180 away from the cleaning member 110. The clean water inlet 505 is arranged close to the first driving member 161 and is in communication with the clean water outlet 501 in the receiving cavity 190. One end of the transition pipe section 5042 is in communication with the outlet of the heat conducting pipe section 5041, and the other end of the transition pipe section 5042 is in communication with the clean water inlet 505. The transition pipe section 5042 facilitates the connection between the clean water delivery pipe 504 and the clean water inlet 505. Since the clean water inlet 505 is arranged close to the first driving member 161, the probability of interference between the second connecting member 302 and the clean water delivery pipe 504 when the second connecting member 302 moves relative to the first connecting member 301 is reduced, thereby improving the stability and reliability of the operation of the cleaning assembly 100.

[0428] Please refer to Figure 135 and Figure 136 During the rotation of the cleaning member 110, the cleaning member 110 first passes through the clean water outlet 501 to replenish clean water, and then passes through the sewage collection cavity 503 to collect sewage. Specifically, in the present embodiment, the cleaning assembly 100 further comprises a wiping structure 710. The wiping structure 710 comprises a first wiping member 701 and a second wiping member 702. The first wiping member 701 and the second wiping member 702 are arranged in a spaced manner in the rotation direction of the cleaning member 110 and extend along the length direction of the cleaning member 110. The first wiping member 701, the second wiping member 702, and the inner wall of the housing 180 form the sewage collection cavity 503. During the cleaning operation of the cleaning member 110, the cleaning member 110 first passes through the first wiping member 701, and then passes through the second wiping member 702. Under the extrusion of the first wiping member 701 and the second wiping member 702, the sewage on the cleaning member 110 is scraped into the sewage collection cavity 503. Figure 134 、 Figure 135 and Figure 137 The sewage outlet 5021 is connected to the sewage tank 600 through a pipeline. The sewage in the sewage collection cavity 503 is pumped into the sewage tank 600 through the sewage outlet 502, thereby achieving the collection of the sewage on the cleaning member 110.

[0429] It should be noted that since the surface of the cleaning member 110 is flat under the extrusion after the cleaning member 110 passes through the first wiping member 701 and the second wiping member 702, the cleaning effect of the cleaning member 110 is affected. Based on this, please refer to Figure 135, 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 collecting cavity 503. It can be understood that when the water scraping structure 710 flattens the cleaning element 110 after scraping the sewage on the cleaning element 110, the fluffing roller 170 acts on the cleaning element 110 and turns up the fluff on the surface of the cleaning element 110, so that the cleaning element 110 is in a fluffy state again, which can reduce the decrease of cleaning effect caused by the flattening of the cleaning element 110 by the water scraping structure 710.

[0430] In order to further improve the water scraping effect of the water scraping structure 710, optionally, in an embodiment of the utility model, referring to Figure 135 and Figure 136 , the first water scraping element 701 comprises a plurality of first comb teeth 7011 arranged at intervals. One end of the first comb tooth 7011 is connected with the inner wall of the shell 180, and the other end of the first comb tooth 7011 extends towards the cleaning element 110. The second water scraping element 702 is a scraping strip structure, one end of the second water scraping element 702 is connected with the inner wall of the shell 180, and the other end extends towards one side of the cleaning element 110. In this way, on the one hand, the plurality of first comb teeth 7011 can block the large particles on the cleaning element 110 from entering the sewage collecting cavity 503, greatly reducing the probability of large particles blocking the sewage suction port 502. On the other hand, it can also reduce the contact area between the first water scraping element 701 and the cleaning element 110, which is beneficial to reducing the friction and wear generated during the rotation of the cleaning element 110, prolonging the service life of the cleaning element 110. At the same time, since the second water scraping element 702 adopts a scraping strip structure, a relatively tight extrusion contact surface can be formed between the second water scraping element 702 and the cleaning element 110, which is beneficial to preventing the sewage from flowing out of the sewage collecting cavity 503 and polluting the surface to be cleaned.

[0431] Optionally, in another embodiment, referring to Figure 135 and Figure 136 , the inner wall of the shell 180 is further provided with a comb element 720, and the comb element 720 is in interference contact with the cleaning element 110. Along the advancing direction of the cleaning device 1000, the comb element 720 is located at the front end of the first water scraping element 701. When the cleaning element 110 performs the cleaning operation, the cleaning element 110 passes through the comb element 720, the first water scraping element 701 and the second water scraping element 702 in sequence. The comb element 720 extends along the length direction of the cleaning element 110 and comprises a plurality of second comb teeth 721. Gaps are formed between adjacent second comb teeth 721, and the comb element 720 can block large-size particles from entering the inside of the shell 180, thereby reducing the damage of the large-size particles to the accommodation cavity.

[0432] Referring to Figure 133 and Figure 134The clean water tank 500 is located at the rear edge of the housing 200, which facilitates the base station's replenishment of the clean water tank 500. Similarly, the wastewater tank 600 is typically located at the rear edge of the housing 200 for easy wastewater removal. To save installation space on the housing 200 for the wastewater tank 600 and the clean water tank 500, optionally, in this embodiment, please refer to... Figure 138 and Figure 139 The clean water tank 500 includes a mounting cavity 506, the opening of which faces outwards from the body 200. The shape and size of the mounting cavity 506 match the shape and size of the wastewater tank 600, which is fitted into the mounting cavity 506. This not only allows for the integrated installation of the wastewater tank 600 and the clean water tank 500, facilitating their assembly and disassembly on the body 200, but also reduces the horizontal installation area occupied by the clean water tank 500 and the wastewater tank 600 on the body 200, thereby optimizing the spatial layout of the body 200 and improving the compactness of the equipment.

[0433] To improve the installation stability of the clean water tank 500 on the unit body 200, optionally, please refer to Figure 133 and Figure 134 In one embodiment, a water tank mounting cavity 270 is provided at the rear edge of the body 200, and a clean water tank 500 is accommodated within the water tank mounting cavity 270. The side walls of the clean water tank 500 are fixedly connected to the walls of the water tank mounting cavity 270 by bolts. Please refer to [link / reference]. Figure 134 and Figure 138 The bottom of the clean water tank 500 is also equipped with a support plate 507. One end of the support plate 507 is fixedly connected to the body 200, and the other end of the support plate 507 supports the bottom of the clean water tank 500 and is fixedly connected to the bottom wall of the clean water tank 500. This arrangement forms connection support points on both the side wall and the bottom wall of the clean water tank 500, thereby improving the connection strength between the clean water tank 500 and the body 200. At the same time, since the wastewater tank 600 is installed in the mounting cavity 506, the support plate 507 can also specifically enhance the support strength at the installation position of the wastewater tank 600, further improving the installation stability of the wastewater tank 600 and the clean water tank 500 on the body 200.

[0434] Optionally, in an embodiment, the clean water tank 500 is provided with a first water level detection assembly (not shown in the figure), and the dirty water tank 600 is provided with a second water level detection assembly (not shown in the figure). The first water level detection assembly can detect the water level in the clean water tank 500 in real time, so as to timely supplement water to the clean water tank 500 and ensure the immersion degree of the cleaning element 110. The second water level detection assembly can detect the water level in the dirty water tank 600 in real time, so as to timely discharge the dirty water in the dirty water tank 600 and avoid the dirty water overflowing to pollute the ground. The structures of the first water level detection assembly and the second water level detection assembly can be the same or different. Optionally, in the embodiment, the structures of the first water level detection assembly and the second water level detection assembly are the same.

[0435] The following embodiment takes the first water level detection assembly as an example to introduce the structure.

[0436] The first water level detection assembly includes a floating ball, a magnet and a Hall sensor. The floating ball is suspended in the clean water tank 500 and can float up and down with the clean water level. The magnet is fixed inside the floating ball and moves synchronously with the floating ball when the floating ball moves up and down with the clean water level. The Hall sensor is fixed on the top wall or side wall of the clean water tank 500 and is used to detect the change of the magnetic field of the magnet. When the magnet moves to the vicinity of the Hall sensor with the floating ball, the Hall sensor can sense the change of the magnetic field and output a corresponding electric signal. When the liquid level of the clean water in the clean water tank 500 rises, the floating ball rises with the liquid level and drives the magnet to move upward. When the magnet approaches the Hall sensor, the Hall sensor detects that the magnetic field strength increases and outputs a high-level signal. When the liquid level drops, the floating ball sinks with the liquid level and drives the magnet to move downward. When the magnet moves away from the Hall sensor, the Hall sensor detects that the magnetic field strength decreases and outputs a low-level signal. Through the high and low level changes of the output signal of the Hall sensor, the change of the liquid level of the clean water in the clean water tank 500 can be judged, so as to realize real-time monitoring and control of the liquid level.

[0437] Of course, in other embodiments, the first water level detection assembly and the second water level detection assembly can also be ultrasonic water level detection assemblies, capacitive water level detection assemblies and other components that can realize liquid level detection.

[0438] Please refer to Figure 137 , Figure 143 and Figure 145The clean water tank 500 comprises a clean water tank inlet 511 and a clean water tank outlet 512, and the clean water tank outlet 512 is communicated with the water inlet of the clean water conveying pipe 504. The clean water conveying pipe 504 is provided with a water pump (not shown in the figure), which is arranged on the machine body 200. The water pump is communicated with the water inlet of the heat conduction pipe section 5041 and the clean water tank outlet 512. Through the operation of the water pump, the clean water in the clean water tank 500 can be pumped and conveyed to the clean water outlet 501 position, so as to supplement the clean water for the cleaning member 110 and ensure the consistency and continuity of the cleaning effect.

[0439] Please refer to Figure 137 、 Figure 142 and Figure 143 , the sewage tank 600 comprises a sewage tank inlet 601 and a sewage tank outlet 602. The sewage tank outlet 602 is arranged at the bottom of the sewage tank 600, and the sewage tank inlet 601 is communicated with the sewage outlet outlet 5021 through the sewage pipe. The sewage tank 600 further comprises a negative pressure outlet 603, and a negative pressure pump (not shown in the figure) is further arranged on the machine body 200 and communicated with the negative pressure outlet 603. The negative pressure pump is operated to form a negative pressure in the sewage tank 600. Under the action of the negative pressure, the sewage flows out from the sewage collecting cavity 503, passes through the sewage outlet 502, the sewage outlet outlet 5021 and the sewage pipe in turn, and finally enters the sewage tank 600. By using this sewage discharge mode, the sewage can be efficiently collected, so as to improve the continuity of the cleaning process and the consistency of the cleaning effect.

[0440] Optionally, in an embodiment, please refer to Figure 139 and Figure 149 , the clean water tank 500 comprises a first clean water tank 520, a second clean water tank 530 and a third clean water tank 540, and the inner cavities of the first clean water tank 520, the second clean water tank 530 and the third clean water tank 540 are communicated with each other. Among them, the second clean water tank 530 and the third clean water tank 540 are arranged on the two sides of the sewage tank 600 respectively, and the second clean water tank 530, the third clean water tank 540 and the sewage tank 600 are arranged on the support plate 507, that is, the support plate 507 supports the bottom of the second clean water tank 530, the third clean water tank 540 and the sewage tank 600. The first clean water tank 520 is arranged above the mounting cavity, that is, above the sewage tank 600, and the two ends of the first clean water tank 520 are communicated with the second clean water tank 530 and the third clean water tank 540 respectively.

[0441] Please refer to Figure 142 and Figure 146The bottom of the third clean water tank 540 is provided with a first balance port 541, and the bottom of the second clean water tank 530 is provided with a second balance port 531. A balance pipeline 550 is connected between the first balance port 541 and the second balance port 531. The third clean water tank 540 communicates with the second clean water tank 530 through the first balance port 541, the balance pipeline 550 and the second balance port 531. In this way, the water levels in the third clean water tank 540 and the second clean water tank 530 can be balanced in real time, so as to ensure the stability of the overall center of gravity of the clean water tank 500 and avoid the inclination or unstable operation of the equipment caused by uneven water level.

[0442] Optionally, referring to Figure 141 and Figure 145 , in an embodiment, the sewage tank 600 is provided with a first clean water supplement port 604 and a second clean water supplement port 605. The first clean water supplement port 604 is arranged on a side wall of the sewage tank 600 facing the outside of the fuselage 200, and the second clean water supplement port 605 is arranged on a side wall of the sewage tank 600 facing the inside of the fuselage 200. The first clean water supplement port 604 and the second clean water supplement port 605 are communicated through a clean water supplement pipeline 560 arranged inside the sewage tank 600. The first clean water supplement port 604, the second clean water supplement port 605 and the clean water supplement pipeline 560 jointly form a clean water tank water inlet 511.

[0443] Referring to Figure 141 and Figure 149 , the clean water tank 500 includes a first tank body 570 and a second tank body 580. The first tank body 570 is connected to the support plate 507, the mounting concave cavity 506 is arranged on the first tank body 570, and the second clean water tank 530 and the third clean water tank 540 are formed on the first tank body 570. The second tank body 580 is arranged above the first tank body 570 and cooperates with the second tank body 580 to form the first clean water tank 520. Referring to Figure 143 and Figure 148 , the clean water tank 500 is integrally formed with a water supplement pipeline 508 on a side wall away from the sewage tank 600. The water supplement pipeline 508 extends along the height direction of the clean water tank 500. The lower end of the water supplement pipeline 508 is communicated with the second clean water supplement port 605, and the upper end of the water supplement pipeline 508 is communicated with the first clean water tank 520.

[0444] Specifically, referring to Figure 148The water replenishing pipeline 508 comprises a lower water replenishing pipeline 5081 and an upper water replenishing pipeline 5082, the lower water replenishing pipeline 5081 is formed on the first box body 570, the upper water replenishing pipeline 5082 is formed on the second box body 580, and the lower water replenishing pipeline 5081 and the upper water replenishing pipeline 5082 are connected in a sealed mode after the first box body 570 and the second box body 580 are connected in a butt joint mode. The lower end of the lower water replenishing pipeline 5081 is communicated with the second clean water replenishing opening 605, and the upper end of the upper water replenishing pipeline 5082 is communicated with the clean water tank 500, so that the second clean water replenishing opening 605 and the clean water tank 500 are communicated.

[0445] When the clean water in the clean water tank 500 is used up and needs to be replenished, the cleaning equipment 1000 moves to the base station, and the first clean water replenishing opening 604 on the clean water tank 500 is aligned with the water outlet on the base station or the water supply outlet of the municipal pipeline. The base station is provided with a water pump, and under the suction of the water pump, the clean water flows through the first clean water replenishing opening 604, the clean water replenishing pipeline 560, the second clean water replenishing opening 605, the lower water replenishing pipeline 5081 and the upper water replenishing pipeline 5082 in sequence, and finally enters the clean water tank 500, thereby completing the replenishing operation of the clean water tank 500. By arranging the lower water replenishing pipeline 5081 and the upper water replenishing pipeline 5082 to replenish the clean water tank 500, compared with the structure of replenishing water by using an external pipeline, the structure does not need to additionally install a water replenishing pipeline, thereby simplifying the assembly process and being beneficial to improving the installation efficiency. Meanwhile, since the lower water replenishing pipeline 5081 is integrally formed on the first box body 570 and the upper water replenishing pipeline 5082 is integrally formed on the second box body 580, no additional installation space is occupied outside the clean water tank 500, which is beneficial to optimizing the space layout on the machine body 200 and improving the compactness of the overall structure of the cleaning equipment 1000.

[0446] Optionally, in an embodiment of the present application, referring to Figure 137 The shell 180 is further provided with a dirt detection unit 800 for detecting the dirt degree of the cleaning piece 110 in the containing cavity 190. The number of the dirt detection unit 800 is not limited, and in the embodiment, the dirt detection unit 800 is provided with one. In other embodiments, the dirt detection unit 800 can also be provided with multiple, and the multiple dirt detection units 800 are arranged along the length direction of the containing cavity. In this way, the multi-area detection of the cleaning piece 110 can be realized, so that higher dirt detection precision can be obtained.

[0447] Please refer to Figures 150-153The dirty detection unit 800 includes a color sensor 801 and a light supplement 802. The shell 180 includes a view window 1807 between the clean water outlet 501 and the dirty water collection cavity 503. The color sensor 801 is mounted on the shell 180 and arranged above the view window 1807 to collect the color of the cleaning element 110 through the view window 1807, and determine the dirtiness of the cleaning element 110 based on the color of the cleaning element 110. There is a certain height space between the color sensor 801 and the cleaning element 110, so that the color sensor 801 can obtain a certain field of view angle to meet the detection area requirement. The view window 1807 can also be covered with a transparent piece such as glass, quartz, etc. The transparent piece can block the dirty water on the cleaning element 110 from splashing on the color sensor 801, affecting the accuracy of the dirty detection. The light supplement 802 includes but is not limited to an LED lamp, and the light supplement 802 is arranged above the transparent piece to illuminate the area of the view window 1807, so as to improve the detection accuracy of the color sensor 801.

[0448] Before the cleaning element 110 starts to work, the color sensor 801 collects a surface image of the cleaning element 110 as a reference image. After the cleaning element 110 works for a period of time, the color sensor 801 collects a surface image of the cleaning element 110 again, and compares the image with the reference image. By analyzing the comparison result, the dirtiness of the surface of the cleaning element 110 is determined. When the dirtiness of the surface of the cleaning element 110 is detected to exceed a preset threshold, the control system controls the cleaning device 1000 to return to the base station to clean the cleaning element 110 according to the detection result. By arranging the dirty detection unit 800, the dirtiness of the cleaning element 110 can be monitored in real time, and the consistency of the cleaning effect can be ensured. At the same time, by monitoring the dirtiness of the cleaning element 110, unnecessary cleaning operation can be avoided, so as to save water resources.

[0449] Of course, in the embodiments of the present application, the dirty detection of the cleaning element 110 is not limited to the color sensor 801.

[0450] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
