Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, specifically to a cleaning component and cleaning equipment. Background Technology

[0002] In existing technologies, cleaning components typically have only one squeegee structure within their mounting cavity. This squeegee uses a scraper blade to make interference contact with the cleaning component inside the cavity, squeezing off wastewater and stains. However, during the cleaning process, foreign objects such as particles (e.g., small stones) often adhere to the cleaning component. After being scraped off by the scraper blade, these foreign objects can easily enter the mounting cavity. These foreign objects can not only cause the cleaning component to rotate improperly, leading to jamming, but also generate abnormal noise due to friction between the foreign objects and the cavity walls. In severe cases, continuous friction can even damage the cavity walls, thus affecting the cleaning effect and lifespan of the cleaning component. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides a cleaning component and cleaning equipment to improve the technical problem that foreign objects on the cleaning component can easily enter the installation cavity.

[0004] To achieve the above and other related objectives, the first aspect of this utility model provides a cleaning assembly, which includes: a bracket, a cleaning structure, a squeegee structure, and a comb structure; the bracket has a mounting cavity; the cleaning structure is rotatably mounted in the mounting cavity, and a cleaning element is provided on the surface of the cleaning structure to clean the surface to be cleaned; the squeegee structure is disposed in the mounting cavity and at least partially contacts the cleaning element to scrape off wastewater on the cleaning element when the cleaning structure rotates; the comb structure is disposed in the mounting cavity and at least partially presses against the cleaning element; wherein the comb structure is configured to scrape at least a portion of the particles on the surface of the cleaning element to the outside of the mounting cavity when the cleaning structure rotates.

[0005] The beneficial effects of this design are as follows: By incorporating a comb-like structure within the mounting cavity, the cleaning component passes sequentially through both the comb and the squeegee as the cleaning mechanism rotates within the cavity. As the cleaning component passes the comb, the comb scrapes off some of the particles adsorbed on it, allowing these particles to fall outside the mounting cavity. This reduces the probability of particles entering the mounting cavity with the rotating cleaning component and falling into the gap between the squeegee and the cleaning component. Consequently, it reduces the likelihood of particles clogging the gap and causing the cleaning component to rotate poorly or become stuck, thus improving the cleaning efficiency of the cleaning assembly. Furthermore, since the comb removes some particles, the surface of the cleaning component is cleaner, facilitating the subsequent squeegee's handling of fine dirt. Moreover, because the particles are scraped off to the outside of the mounting cavity, the contact time between the particles and the inner wall of the cavity is reduced, mitigating collision and friction and thus minimizing damage to the cavity walls, ensuring the lifespan of the cleaning assembly.

[0006] In one embodiment of the present invention, the cleaning structure includes a roller, which is rotatably connected in the mounting cavity, and the cleaning component is wound around the outer circumferential surface of the roller.

[0007] The advantages of this design are as follows: By employing a roller structure and winding the cleaning component around it, the continuous rotation of the roller ensures that the cleaning component remains in constant contact with the surface to be cleaned, achieving efficient cleaning. Simultaneously, the compact roller structure, with the cleaning component wound around it, saves installation space and improves the overall compactness of the cleaning assembly.

[0008] In one embodiment of the present invention, the comb tooth structure includes a plurality of first comb teeth, which are arranged along the length direction of the mounting cavity.

[0009] The advantages of this design are as follows: By arranging multiple first comb teeth along the length of the mounting cavity, it ensures that the first comb teeth cover the entire surface of the part being cleaned during the cleaning process, preventing any omissions in particle removal and thus improving the particle removal effect. Furthermore, the arrangement of multiple first comb teeth allows them to work synergistically during particle removal, quickly removing particles from the surface of the part being cleaned, improving cleaning quality and ensuring that subsequent squeegee mechanisms can effectively handle fine particles.

[0010] In one embodiment of the present invention, the first comb tooth includes a tooth portion and a connecting portion. The tooth portion is pressed against the surface of the cleaning component. One end of the connecting portion is connected to the tooth portion, and the other end extends along the circumferential direction of the mounting cavity. Along the extension direction of the connecting portion, the cross-section of the connecting portion gradually decreases from the end closer to the tooth portion to the end farther away from the tooth portion.

[0011] The beneficial effects of this design are as follows: By incorporating the teeth and connecting portion, the teeth can contact and press against the surface of the cleaning component, effectively scraping off particles adhering to it. Furthermore, since the cross-section of the connecting portion gradually decreases from the end closest to the teeth to the end furthest from them, this mitigates stress concentration in the circumferential direction during the manufacturing process of the first comb tooth. This results in better resistance to deformation in the circumferential direction for the first comb tooth, thereby improving its durability.

[0012] In one embodiment of this utility model, the side of the teeth facing the cleaning component includes an arc surface, and the rotation axis of the arc surface is coaxially arranged with the rotation axis of the cleaning structure.

[0013] The beneficial effects of this design are as follows: When the teeth and the cleaning component are pressed together, this design ensures uniform contact between them, thereby guaranteeing even force distribution on the surface of the cleaning component, preventing excessive localized wear, and reducing damage to the cleaning component from the teeth. Simultaneously, the arc-shaped surface design increases the pressing area between the teeth and the cleaning component, making it easier for scraped particles to detach from the surface of the cleaning component and preventing secondary adhesion.

[0014] In one embodiment of this utility model, along the height direction of the cleaning component, the distance between the end of the tooth facing away from the connecting part and the surface to be cleaned is not greater than the distance between the rotation axis of the cleaning structure and the surface to be cleaned.

[0015] The advantages of this design are as follows: This design ensures that the height of the end of the teeth away from the connecting part does not exceed the height of the roller's axis, meaning that the point where particles on the cleaning component detach from the teeth is no higher than the roller's axis. This allows particles scraped off by the teeth to fall below the cleaning component under their own weight, reducing the probability of particles falling back onto the cleaning component and ensuring its cleaning effect. Furthermore, it allows particles to fall promptly from the opening below, reducing the time particles remain in the mounting cavity.

[0016] In one embodiment of the present invention, the mounting cavity has an opening on the side facing the surface to be cleaned, and a guide portion is provided on the side of the mounting cavity near the comb tooth structure. One end of the guide portion is connected to the comb tooth structure, and the other end extends toward the opening side. A material discharge channel communicating with the opening is formed between the guide portion and the cleaning component.

[0017] The beneficial effects of this design are as follows: By incorporating a guide section and creating a discharge channel that connects the guide section to the cleaning component and communicates with the opening, particles scraped off by the comb structure first enter the discharge channel after detaching from the cleaning component. After being guided by the guide section, they are then discharged from the opening. This not only guides the scraped particles, ensuring they can smoothly exit the opening and avoid accumulation inside the mounting cavity, thus guaranteeing the cleaning effect of the cleaning component, but also, the guide section provides some constraint to the particles during discharge, thereby reducing particle splashing.

[0018] In one embodiment of this utility model, along the height direction of the cleaning component, the cross-section of the material drop channel gradually increases from the end near the comb structure toward the opening side.

[0019] The beneficial effects of this design are as follows: By gradually increasing the cross-section of the material discharge channel from the end near the comb structure towards the opening, a smaller cross-section is formed at the end near the comb structure (i.e., the inlet end of the material discharge channel), which concentrates and guides particles into the channel, resulting in better guidance. A larger cross-section is formed on the side near the opening (i.e., the outlet end of the material discharge channel), which can accommodate more particles and reduce the possibility of blockage. Simultaneously, as the cross-section of the material discharge channel gradually increases, the flow velocity of the particles within the channel gradually decreases, reducing the kinetic energy of the particles upon discharge and thus minimizing splashing.

[0020] In one embodiment of the present invention, the wiping structure includes a first wiping component and a second wiping component, with a water receiving groove between the first wiping component and the second wiping component. When the cleaning structure rotates, the cleaning component passes through the first wiping component and the second wiping component in sequence, and under the squeezing action of the first wiping component and / or the second wiping component, the sewage on the cleaning component is scraped into the water receiving groove.

[0021] The beneficial effects of this design are as follows: By setting up a first squeegee and a second squeegee, the cleaning component will pass through the first and second squeegees sequentially during rotation. When passing the first squeegee, the wastewater on the cleaning component can be removed once. When passing the second squeegee, the residual wastewater on the cleaning component can be further removed. Therefore, during the entire rotation process, the squeegee structure can perform two wastewater removal actions on the cleaning component, which helps to improve the cleaning effect of the cleaning component.

[0022] In one embodiment of the present invention, the first wiping component includes a plurality of spaced second comb teeth, the second wiping component is a wiping strip structure, and the extension height of the first wiping component from the inner wall of the mounting cavity toward the cleaning component is less than the extension height of the second wiping component from the inner wall of the mounting cavity toward the cleaning component.

[0023] The beneficial effects of this design are as follows: Because the first wiper blade has a smaller extension height, the wiping depth on the cleaning component is shallower, facilitating initial wiping as the cleaning component passes over it. Because the second wiper blade has a larger extension height, the wiping depth on the cleaning component is greater, which helps to further remove residual wastewater. Simultaneously, because the first wiper blade uses a second comb-tooth structure, the contact area with the cleaning component is smaller, reducing friction and wear during rotation and extending the service life of the cleaning component. Because the second wiper blade uses a strip structure, it can form a tighter compression contact surface with the cleaning component, thus reducing wastewater leakage.

[0024] In a second aspect, this utility model also provides a cleaning device, which includes the cleaning components of any of the above embodiments. Attached Figure Description

[0044] Please see Figures 1 to 13 This utility model provides a cleaning component 100 and a cleaning device 200. The cleaning component 100 is provided with a comb structure 140, which is configured to scrape at least part of the particles on the surface of the cleaning component 121 to the outside of the mounting cavity 111 when the cleaning structure 120 rotates. Therefore, it can improve the problem that foreign objects on the cleaning component 121 can easily enter the mounting cavity 111 during the cleaning operation, thereby improving the cleaning effect and service life of the cleaning component 100.

[0045] Please see Figure 1 The cleaning device 200 provided by this utility model includes a body 210 and a cleaning component 100.

[0046] The interior of the body 210 has a storage space to accommodate various components of the cleaning equipment 200. The shape of the body 210 can be arbitrary, such as circular, elliptical, or D-shaped. The cleaning equipment 200 may also include a walking assembly conventionally provided on existing cleaning equipment 200, located below the body 210 to drive the cleaning equipment 200 to achieve self-movement.

[0047] The cleaning component 100 can be detachably connected to the main body 210. The detachable connection method can be a snap-fit ​​connection, a bolt-fit connection, etc. The cleaning component 100 is configured for wet mopping. The main body 210 is equipped with a water replenishment mechanism (not shown in the figure). The water outlet of the water replenishment mechanism is connected to the cleaning element 121 on the cleaning component 100 to provide liquid to the cleaning element 121. The liquid can be cleaning fluid or ordinary tap water, depending on the wet mopping requirements of the cleaning equipment 200. The specific structure of the water replenishment mechanism on the main body 210 can be found in the relevant descriptions of water replenishment structures in existing cleaning equipment 200, and will not be repeated here.

[0048] It should be noted that the number of cleaning components 100 on the cleaning device 200 can be one or more sets, depending on the cleaning area and cleaning efficiency requirements of the cleaning device 200. Specifically, in this embodiment, the cleaning device 200 is provided with one set of cleaning components 100, which are installed on the bottom of the body 210 to perform cleaning operations on the surface 300 to be cleaned during the movement of the cleaning device 200.

[0049] Please see Figures 1 to 3 In one embodiment of this utility model, the cleaning component 100 includes a bracket 110, a cleaning structure 120, a squeegee structure 130, and a comb structure 140. The bracket 110 is installed below the body 210 and has a mounting cavity 111. The cleaning structure 120 is rotatably installed in the mounting cavity 111, and a cleaning element 121 is provided on the surface of the cleaning structure 120. The cleaning element 121 can be a cleaning material such as brush bristles or a sponge to clean the surface 300 to be cleaned. The surface 300 to be cleaned can be, but is not limited to, the surface of an object or scene such as a floor, tabletop, glass, or wall. For ease of description, the surface 300 to be cleaned in the following description will be based on the floor as an example.

[0050] It should be noted that the cleaning structure 120 in this embodiment can be a roller type or a tracked type, etc. In actual design, it needs to be determined according to the cleaning operation requirements of the cleaning equipment 200. Furthermore, there are multiple options for how the cleaning structure 120 is rotatably installed within the mounting cavity 111. For example, the cleaning structure 120 can rotate within the mounting cavity 111 solely through friction between the cleaning component 121 and the surface 300 to be cleaned, or it can be achieved by setting a drive assembly, such as a motor and transmission assembly, to drive the rotating shaft of the cleaning structure 120 to rotate, thus realizing the rotation of the cleaning structure 120 within the mounting cavity 111.

[0051] Please see Figure 5The squeegee structure 130 is disposed within the mounting cavity 111 and at least partially contacts the cleaning component 121 to scrape away wastewater from the cleaning component 121 when the cleaning structure 120 rotates. It should be noted that when the squeegee structure 130 and the cleaning component 121 are in contact, they can be in an interference fit, forming mutual compression, or they can only be in surface contact without compression, as long as it ensures that the cleaning structure 120 can scrape away wastewater from the cleaning component 121 when it rotates. The squeegee structure 130 can be integrally formed and connected to the inner wall of the mounting cavity 111, or it can be fixed to the inner wall of the mounting cavity 111 by snap-fit ​​or threaded connection. The squeegee structure 130 can be a squeegee structure, a comb structure 140, or other structures, as long as it can scrape away wastewater from the cleaning component 121 when the cleaning structure 120 rotates. In this embodiment, the specific structure of the squeegee structure 130 is not limited.

[0052] It should be noted that the cleaning equipment 200 is usually also equipped with a wastewater tank. The wastewater scraped off by the squeegee structure 130 on the cleaning component 121 flows into the wastewater tank through the wastewater outlet to collect the wastewater. For the location and structure of the wastewater tank and wastewater outlet on the cleaning equipment 200, please refer to the relevant structural descriptions in existing cleaning equipment 200, which will not be repeated here.

[0053] Please see Figure 3 and Figure 5 The comb structure 140 is disposed in the mounting cavity 111. At least a portion of the comb structure 140 extends toward the surface of the cleaning component 121 and makes interference contact with the cleaning component 121 to form a squeezing action on the cleaning component 121.

[0054] In the direction of travel of the cleaning device 200, the comb structure 140 is located in front of the squeegee structure 130. When the cleaning device 200 performs a cleaning operation, as the cleaning structure 120 rotates, the cleaning component 121 first passes through the comb structure 140, and then through the squeegee structure 130. The comb structure 140 is configured to scrape at least a portion of the particles on the surface of the cleaning component 121 to the outside of the mounting cavity 111 as the cleaning structure 120 rotates. It should be noted that most of the particles scraped off by the comb structure 140 are larger than the gap between the squeegee structure 130 and the cleaning component 121, i.e., larger particles of debris generated by the cleaning assembly 100 during the cleaning operation.

[0055] Specifically, please refer to Figure 5In this embodiment, the mounting cavity 111 has an opening 1111 on the side near the surface 300 to be cleaned, and the cleaning member 121 extends at least partially to the outside of the opening 1111 to clean the surface 300 to be cleaned. The comb structure 140 scrapes particles from the surface of the cleaning member 121 to the outside of the mounting cavity 111, that is, particles scraped off the cleaning member 121 by the comb structure 140 can fall from the opening 1111 to the outside of the mounting cavity 111.

[0056] It should be understood that although the relative positions between the wiping structure 130 and the comb structure 140 are not specifically limited, preferably, in this embodiment, please refer to... Figure 5 The squeegee structure 130 and the comb structure 140 are located on both sides of the opening 1111, and are both positioned close to the opening 1111. This arrangement reduces the height of the squeegee structure 130 and the comb structure 140 inside the mounting cavity 111, which not only facilitates the comb structure 140 in scraping particles from the cleaning component 121 to the outside of the mounting cavity 111, but also facilitates the collection of wastewater scraped off the cleaning component 121.

[0057] In this embodiment, by providing a comb structure 140 within the mounting cavity 111, when the cleaning structure 120 rotates within the mounting cavity 111 to perform cleaning operations, the cleaning component 121 sequentially passes through the comb structure 140 and the squeegee structure 130. As the cleaning component 121 passes through the comb structure 140, the comb structure 140 can scrape off some of the particles adsorbed on the cleaning component 121, allowing the particles to fall outside the mounting cavity 111. This reduces the probability of particles entering the mounting cavity 111 with the rotation of the cleaning component 121 and falling into the gap between the squeegee structure 130 and the cleaning component 121. Based on this, the probability of the cleaning component 121 rotating poorly or getting stuck due to particles clogging the gap can be reduced, thereby improving the cleaning efficiency of the cleaning assembly 100. Since the comb structure 140 removes some particles, the surface of the cleaning component 121 becomes cleaner, facilitating the subsequent treatment of fine dirt by the squeegee structure 130. Furthermore, since the particles are scraped off to the outside of the mounting cavity 111, the contact time between the particles and the inner wall of the mounting cavity 111 can be reduced, the degree of collision and friction can be alleviated, thereby reducing the damage to the wall of the mounting cavity 111 and ensuring the service life of the cleaning component 100.

[0058] Given the wide range of applications for roller-type cleaning components 100, optionally, please refer to Figure 3 , Figure 5 , Figure 7 and Figure 8In one embodiment of this utility model, the cleaning structure 120 includes a roller 122, which is rotatably connected within a mounting cavity 111. A cleaning component 121 is wound around the outer circumferential surface of the roller 122. The mounting cavity 111 has an approximately cylindrical structure to match the shape of the roller 122. The length direction of the mounting cavity 111 (e.g., ...) Figure 9 The cleaning structure 120 (shown on the X-axis) has a slewing support 1113 at one end and a card interface 1114 at the other end. The cleaning structure 120 also includes a drive assembly 123, which can drive the slewing support 1113 to rotate. The drive assembly 123 can be a motor and transmission belt structure, or a motor and gear assembly, etc.

[0059] Please see Figures 7 to 9 The roller 122 has a fixed support end 1221 and a rotating support end 1222 at its two ends. The fixed support end 1221 is connected to the rotary support 1113, and the rotating support end 1222 is engaged with the locking interface 1114. When the drive assembly 123 operates, it drives the rotary support 1113 to rotate. The rotation of the rotary support 1113 drives the fixed support end 1221 to rotate, which in turn drives the roller 122 and the rotating support end 1222 to rotate synchronously, realizing the rotation of the cleaning structure 120 relative to the mounting cavity 111. In this embodiment, by adopting the design of the roller 122 structure and winding the cleaning component 121, the continuous rotation of the roller 122 can keep the cleaning component 121 in continuous contact with the surface 300 to be cleaned, achieving efficient cleaning of the surface 300. At the same time, since the roller 122 structure is relatively compact and the cleaning component 121 is wound on it, it can save installation space and improve the structural compactness of the cleaning assembly 100.

[0060] To facilitate the forming and processing of the comb tooth structure 140, optionally, please refer to... Figure 3 and Figure 9In one embodiment of this utility model, the comb tooth structure 140 is an elongated structure extending along the length of the mounting cavity 111. The comb tooth structure 140 includes a plurality of first comb teeth 141 arranged in parallel, and the plurality of first comb teeth 141 are arranged along the length of the mounting cavity 111. The plurality of first comb teeth 141 can be arranged at equal intervals or at unequal intervals. Optionally, in this embodiment, the plurality of first comb teeth 141 are arranged at equal intervals along the length of the mounting cavity 111. This arrangement simplifies the structural design of the plurality of first comb teeth 141, simplifies the molding process, and helps reduce production costs. The plurality of first comb teeth 141 can be integrally formed on the inner wall of the mounting cavity 111, or they can be fixedly connected to the inner wall of the mounting cavity 111 by snap-fit ​​or bolts. Optionally, in this embodiment, the first comb teeth 141 are integrally formed on the inner wall of the mounting cavity 111. This arrangement can save the assembly process between the first comb teeth 141 and the mounting cavity 111, and improve the installation efficiency of the comb tooth structure 140. The number of first comb teeth 141 and the spacing between adjacent first comb teeth 141, i.e., the density of the multiple first comb teeth 141, are not specifically limited in this embodiment. In actual design and production, the density of the multiple first comb teeth 141 needs to be adjusted according to the size of the particles to be scraped off on the cleaning component 121.

[0061] By arranging multiple first comb teeth 141 at equal intervals along the length of the mounting cavity 111, it is ensured that the first comb teeth 141 can cover the entire surface of the cleaning component 121 during the cleaning operation, avoiding any omissions in the particle scraping process, thereby improving the particle removal effect. Furthermore, the arrangement of multiple first comb teeth 141 can work synergistically during the particle scraping process, thereby quickly removing particles from the surface of the cleaning component 121, which is beneficial to improving the cleaning quality and ensuring that the subsequent squeegee structure 130 can effectively handle fine particles.

[0062] Considering the forming process of the first comb tooth 141 on the inner wall of the mounting cavity 111, optionally, please refer to Figure 6 and Figure 11 In one embodiment of this utility model, the first comb tooth 141 includes a tooth portion 1411 and a connecting portion 1412. The tooth portion 1411 is in interference contact with the surface of the cleaning member 121 to form mutual compression. One side of the tooth portion 1411 is connected to the inner wall of the mounting cavity 111, and the other side of the tooth portion 1411 extends toward one side of the cleaning member 121. One end of the connecting portion 1412 is connected to the tooth portion 1411, and the other end of the connecting portion 1412 extends along the circumferential direction of the mounting cavity 111. The spacing between adjacent connecting portions 1412 is equal to the spacing between adjacent tooth portions 1411, that is, the thickness of the tooth portion 1411 is the same as the thickness of the connecting portion 1412.

[0063] Please see Figure 6Along the extending direction of the connecting portion 1412, i.e., along the circumferential direction of the mounting cavity 111, the cross-section of the connecting portion 1412 gradually decreases from the end near the tooth portion 1411 to the end away from the tooth portion 1411. The cross-section of the connecting portion 1412 can be of various shapes, such as an approximate triangular structure or an approximate trapezoidal structure, as long as it achieves the goal of gradually decreasing the cross-section of the connecting portion 1412 from the end near the tooth portion 1411 to the end away from the tooth portion 1411. Optionally, in this embodiment, the cross-section of the connecting portion 1412 is an approximate triangular structure. It should be noted that the relative position between the connecting portion 1412 and the tooth portion 1411 is not limited. For example, the connecting portion 1412 can be located above the tooth portion 1411, i.e., on the side away from the opening 1111. The connecting portion 1412 can also be located below the tooth portion 1411, i.e., on the side near the opening 1111.

[0064] In this embodiment, by providing the teeth 1411 and the connecting portion 1412, on the one hand, the teeth 1411 can contact and press against the surface of the cleaning component 121, thereby scraping off particles attached to the cleaning component 121. On the other hand, since the cross-section of the connecting portion 1412 gradually decreases from the end closer to the teeth 1411 to the end farther away from the teeth 1411, this can improve the stress concentration phenomenon generated in the circumferential direction during the manufacturing process of the first comb tooth 141, thereby enabling the first comb tooth 141 to have better resistance to deformation in the circumferential direction, thus improving the durability of the first comb tooth 141.

[0065] While the surface shape of the tooth 1411 facing the cleaning component 121 is not specifically limited, provided that the squeezing requirements between the tooth 1411 and the cleaning component 121 are met, considering the uniformity of force during squeezing, in one embodiment of this invention, the side of the tooth 1411 facing the cleaning component 121 may include an arc surface 14111, the rotation axis of which is coaxially arranged with the rotation axis of the cleaning structure 120. In this embodiment, the rotation axis of the cleaning structure 120 is the same as the rotation axis of the roller 122. This arrangement ensures uniform contact between the tooth 1411 and the cleaning component 121 during squeezing, thereby ensuring the uniformity of force on the surface of the cleaning component 121, avoiding excessive local wear, and reducing damage to the cleaning component 121 by the tooth 1411. Meanwhile, the design of the arc surface 14111 can increase the squeezing area between the teeth 1411 and the cleaning part 121, making it easier for the scraped particles to detach from the surface of the cleaning part 121 and avoid secondary adhesion.

[0066] To further reduce the probability of scraped particles re-adhering to the cleaning component 121, optionally, please refer to Figure 5 , Figure 6 and Figure 12 In one embodiment of this utility model, along the circumferential direction of the mounting cavity 111, the tooth 1411 is located on the side of the connecting portion 1412 near the opening 1111. When the cleaning assembly 100 rotates to perform cleaning operations, particles on the cleaning member 121 detach from the end of the tooth 1411 away from the connecting portion 1412. Along the height direction of the cleaning assembly 100 (e.g., along the height direction of the cleaning assembly 100...) Figure 12 As shown on the Z-axis, the height of the end of the toothed part 1411 away from the connecting part 1412 from the surface to be cleaned 300 is H1, and the height of the rotation axis of the cleaning structure 120 (i.e., the rotation axis of the roller 122) from the surface to be cleaned 300 is H2, and H1 is not greater than H2. This setting ensures that the height of the end of the toothed part 1411 away from the connecting part 1412 does not exceed the height of the rotation axis of the roller 122, that is, the position where the particles on the cleaning part 121 detach from the toothed part 1411 is not higher than the rotation axis of the roller 122. This allows the particles scraped off by the toothed part 1411 to fall below the cleaning part 121 under their own gravity, which not only reduces the probability of the scraped particles falling back onto the cleaning part 121 and ensures the cleaning effect of the cleaning part 121, but also allows the particles to fall off from the opening 1111 below in a timely manner, reducing the residence time of the particles in the mounting cavity 111.

[0067] In one embodiment of this utility model, please participate. Figure 5 , Figure 6 and Figure 11 The mounting cavity 111 has a guide portion 1112 on the side near the comb tooth structure 140. One end of the guide portion 1112 is connected to the comb tooth structure 140, and the other end of the guide portion 1112 extends toward the opening 1111. Specifically, the guide portion 1112 is connected to the comb tooth structure 140 in the direction away from the connecting portion 1412. The guide portion 1112 may be part of the wall of the mounting cavity 111, or it may be another independent part additionally installed at the opening 1111 of the mounting cavity 111. Optionally, in this embodiment, the guide portion 1112 is part of the wall of the mounting cavity 111. The guide portion 1112 may be an arc surface structure, a sloped surface structure, or a vertical surface structure, etc., and this embodiment is not limited to these.

[0068] A discharge channel 150 is formed between the guide section 1112 and the cleaning component 121, and the discharge channel 150 communicates with the opening 1111. It should be understood that the shape of the discharge channel 150 varies depending on the shape of the guide section 1112. By providing the guide section 1112 and forming a discharge channel 150 communicating with the opening 1111 between the guide section 1112 and the cleaning component 121, the particles scraped by the comb structure 140, after detaching from the cleaning component 121, first enter the discharge channel 150, are guided by the guide section 1112, and then discharged from the opening 1111. This not only guides the scraped particles, ensuring they can be smoothly discharged from the opening 1111 and preventing accumulation inside the mounting cavity 111, thus ensuring the cleaning effect of the cleaning component 100, but also, the guide section 1112 constrains the particles during discharge, thereby reducing particle splashing.

[0069] In one embodiment of this utility model, please refer to Figure 6 Along the height direction of the cleaning component 100, the cross-section of the material discharge channel 150 gradually increases from the end near the comb tooth structure 140 toward the opening 1111. There are various ways to achieve this gradual increase in the cross-section of the material discharge channel 150 from the end near the comb tooth structure 140 toward the opening 1111. In this embodiment, the thickness of the guide portion 1112 gradually decreases from the tooth portion 1411 toward the opening 1111, thereby achieving the gradual increase in the cross-section of the material discharge channel 150 from the end near the comb tooth structure 140 toward the opening 1111. In other embodiments, a vertically structured guide portion 1112 can be provided, where one end of the guide portion 1112 is connected to the comb tooth structure 140, and the other end of the guide portion 1112 extends vertically toward the opening 1111. Since the cleaning component 121 has an arc surface 14111 structure, the distance between the guide part 1112 and the cleaning component 121 will gradually increase in the vertical direction from the comb structure 140 to the opening 1111. This also allows the cross-section of the material discharge channel 150 to gradually increase from the end near the comb structure 140 to the side of the opening 1111.

[0070] By gradually increasing the cross-section of the discharge channel 150 from the end near the comb structure 140 towards the opening 1111, a smaller cross-section is formed at the end near the comb structure 140 (i.e., the inlet end of the discharge channel 150), which concentrates and guides particles into the channel, resulting in better guidance. A larger cross-section is formed at the side near the opening 1111 (i.e., the outlet end of the discharge channel 150), which can accommodate more particles and reduce the possibility of blockage. Simultaneously, as the cross-section of the discharge channel 150 gradually increases, the flow velocity of the particles within the discharge channel 150 gradually decreases, reducing the kinetic energy of the particles upon discharge and thus reducing splashing.

[0071] In one embodiment of this utility model, please refer to Figure 5 and Figure 11 The wiping structure 130 includes a first wiping element 131 and a second wiping element 133, with a water-receiving groove 134 between them. The first wiping element 131 and the second wiping element 133 extend along the length of the mounting cavity 111 and substantially cover the entire length of the cleaning element 121. The first wiping element 131 and the second wiping element 133 can be separate structures, each individually connected to the wall of the mounting cavity 111, forming the water-receiving groove 134 between the first wiping element 131, the second wiping element 133, and the inner wall of the mounting cavity 111. Alternatively, the first wiping element 131 and the second wiping element 133 can be an integral piece, with the water-receiving groove 134 directly formed on the integral piece. Optionally, to facilitate the installation of the first wiper element 131 and the second wiper element 133 within the mounting cavity 111, in this embodiment, the wiping structure 130 further includes a fixing member 135, to which both the first wiper element 131 and the second wiper element 133 are connected. The fixing member 135 is fixedly connected to the inner wall of the mounting cavity 111, and both the first wiper element 131 and the second wiper element 133 extend from the inner wall of the mounting cavity 111 toward the cleaning member 121.

[0072] Please see Figure 5 and Figure 13When the cleaning structure 120 rotates along the S1 direction, the cleaning component 121 passes sequentially through the first wiper component 131 and the second wiper component 133, meaning the first wiper component 131 is positioned above the second wiper component 133. During the rotation of the cleaning component 121, both the first wiper component 131 and the second wiper component 133 are in interference contact with the cleaning component 121, forming mutual compression to scrape away the wastewater on the cleaning component 121. Specifically, the first wiper component 131 has a drainage gap 136. When the cleaning component 121 passes through the first wiper component 131, the wastewater scraped by the first wiper component 131 can flow into the water receiving tank 134 under the action of gravity through the drainage gap 136. The wastewater scraped by the second wiper component 133 remains directly in the water receiving tank 134 between the first wiper component 131 and the second wiper component 133.

[0073] By configuring a first wiper component 131 and a second wiper component 133, the cleaning component 121 will sequentially pass over the first wiper component 131 and the second wiper component 133 during rotation. Passing over the first wiper component 131 removes wastewater from the cleaning component 121 once, and passing over the second wiper component 133 further removes any remaining wastewater. Throughout the entire rotation process, the wiping structure 130 performs two wastewater removal actions on the cleaning component 121, thereby improving the cleaning effect of the cleaning component 121.

[0074] It should be noted that, in another embodiment, during the rotation of the cleaning member 121, only the first scraper 131 may be in interference contact with the cleaning member 121, forming mutual compression to scrape away the sewage on the cleaning member 121. The second scraper 133 may only contact the surface of the cleaning member 121 to prevent sewage from flowing out of the water receiving tank 134. In other embodiments, during the rotation of the cleaning member 121, only the second scraper 133 may be in interference contact with the cleaning member 121, forming mutual compression to scrape away the sewage on the cleaning member 121.

[0075] To further improve the wiping performance of the wiper structure 130, optionally, please refer to Figure 5 , Figure 8 and Figure 13In one embodiment of this utility model, the first wiper component 131 includes a plurality of spaced-apart second comb teeth 132. One end of each second comb tooth 132 is connected to a fixing member 135, and the other end of each second comb tooth 132 extends toward one side of the cleaning member 121. The plurality of second comb teeth 132 can be spaced at equal intervals or at unequal intervals, and the interval between adjacent second comb teeth 132 forms the aforementioned drainage gap 136. The second comb teeth 132 can be of various shapes and structures, such as rectangular teeth or trapezoidal teeth, depending on whether they meet the wiping requirements of the first wiper component 131. Optionally, in this embodiment, the plurality of second comb teeth 132 are spaced at equal intervals, and the second comb teeth 132 are approximately rectangular teeth. This arrangement simplifies the forming process of the second comb teeth 132 and facilitates manufacturing.

[0076] The second wiper element 133 is a wiping strip structure. One end of the second wiper element 133 is connected to the fixing member 135, and the other end extends towards the cleaning member 121. The extension height of the first wiper element 131 from the inner wall of the mounting cavity 111 towards the cleaning member 121 is less than the extension height of the second wiper element 133 from the inner wall of the mounting cavity 111 towards the cleaning member 121. It should be noted that since both the first wiper element 131 and the second wiper element 133 are connected to the fixing member 135, and the fixing member 135 is in close contact with the inner wall of the mounting cavity 111, the extension height of the first wiper element 131 from the inner wall of the mounting cavity 111 towards the cleaning member 121 is less than the extension height of the second wiper element 133 from the inner wall of the mounting cavity 111 towards the cleaning member 121. This means that the extension height of the first wiper element 131 from the fixing member 135 towards the cleaning member 121 is less than the extension height of the second wiper element 133 from the fixing member 135 towards the cleaning member 121.

[0077] This design allows for a smaller wiping depth on the cleaning element 121 due to the shorter extension height of the first wiper 131, facilitating initial wiping as the cleaning element 121 passes over it. Conversely, the larger extension height of the second wiper 133 results in a deeper wiping depth on the cleaning element 121, further removing residual wastewater. Furthermore, the smaller contact area between the first wiper 131 (using the second comb tooth 132 structure) and the cleaning element 121 reduces friction and wear during rotation, extending its lifespan. Finally, the strip-like structure of the second wiper 133 creates a tighter, more compact contact surface with the cleaning element 121, minimizing wastewater leakage.

[0078] The cleaning component described above in this invention, by incorporating a comb-like structure within the mounting cavity, allows the cleaning component to pass sequentially through both the comb-like structure and the squeegee structure as the cleaning component rotates within the cavity. As the cleaning component passes through the comb-like structure, it is partially scraped off by the comb-like structure, allowing the particles to fall outside the mounting cavity. This reduces the probability of particles entering the gap between the squeegee structure and the cleaning component during rotation, thus decreasing the likelihood of clogging the gap and causing the cleaning component to rotate poorly or become stuck, thereby improving the cleaning efficiency of the component. Furthermore, since the comb-like structure removes some particles, the surface of the cleaning component is cleaner, facilitating the subsequent squeegee structure's handling of fine dirt. Moreover, because the particles are scraped off to the outside of the mounting cavity, the contact time between the particles and the inner wall of the cavity is reduced, decreasing the degree of collision and friction, thereby minimizing damage to the cavity wall and ensuring the service life of the cleaning component. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus having high utilization value and significance.

[0079] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
