Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning component, cleaning equipment and cleaning system. Background Technology

[0002] Cleaning equipment is gradually evolving from basic intelligence to a higher level of intelligence, gradually replacing manual cleaning and becoming an indispensable cleaning helper for many families. Examples include cleaning robots and floor scrubbers. Among the many cleaning devices, sweeping and mopping robots that can mop with running water are more popular with users.

[0003] In related technologies, sweeping and mopping robots typically have a squeegee that contacts the roller to scrape off the wastewater on the roller and guide it to the wastewater tank. However, during the long-term cleaning process of the sweeping and mopping robot, the wastewater attached to the squeegee may drip onto the clean floor, causing secondary pollution to the clean floor.

[0012] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0013] Among the many cleaning devices, robot vacuums and mops that can mop with running water are more popular with users. In related technologies, robot vacuums and mops usually have a squeegee that rubs against the roller to scrape the wastewater off the roller and guide it into the wastewater tank. However, during the long-term cleaning process of the robot vacuum and mop, the wastewater attached to the squeegee may drip onto the clean floor, causing secondary pollution to the clean floor.

[0014] Regarding the above situation, firstly, please refer to [link / reference needed]. Figures 1-4 This application discloses a cleaning component 100, including a mounting bracket 10, a roller 20, a wastewater recovery component 30, and a water receiving component 50. The cleaning component 100 can be installed on a cleaning robot (such as...). Figure 8 As shown in the figure, it is used to clean the surface to be cleaned.

[0015] The roller 20 is rotatably connected to the mounting bracket 10 around the axis of the roller 20. The roller 20 has a first rotation direction. The roller 20 can clean the surface to be cleaned while rotating in the first rotation direction. The roller 20 can be made of elastic and absorbent materials such as sponge or cloth to ensure that it can effectively absorb dirt on the ground during the cleaning process.

[0016] Wastewater recovery assembly 30 is mounted on mounting bracket 10. Wastewater recovery assembly 30 includes a wiper 40, one end of which abuts against roller 20. In the first rotation direction of roller 20, wastewater recovery assembly 30 is used to recover wastewater on roller 20 through wiper 40. Water receiving component 50 is mounted on mounting bracket 10, one end of which abuts against roller 20. In the first rotation direction of roller 20, water receiving component 50 is located downstream of wiper 40.

[0017] Specifically, Figure 4Both the wiper component 40 and the water-receiving component 50 are in contact with the roller 20. When the roller 20 rotates in the first rotation direction, the wiper component 40 can scrape the wastewater off the roller 20 by contacting the outer circumferential surface of the roller 20. The first rotation direction of the roller 20 refers to the direction in which the roller 20 rotates one revolution during the cleaning process of the cleaning assembly 100. In the first rotation direction of the roller 20, the water-receiving component 50 is located downstream of the wiper component 40. That is, the water-receiving component 50 contacts the roller 20 after the wiper component 40. The water-receiving component 50 can intercept the wastewater dripping from the wiper component 40. Since the water-receiving component 50 is in contact with the roller 20, the wastewater dripping from the wiper component 40 can be recycled back onto the roller 20.

[0018] It should be noted that after the roller 20 is installed on the mounting bracket 10, the wiper 40 and the water receiving part 50 always remain in contact with the outer peripheral surface of the roller 20. In this embodiment, by setting the water receiving part 50 downstream of the wiper 40, the water receiving part 50 acts as a second line of defense downstream of the wiper 40. When some sewage on the roller 20 drips down the wiper 40, the water receiving part 50 can intercept the sewage dripping from the wiper 40, so that the sewage dripping from the wiper 40 flows back to the outer peripheral surface of the roller 20 and is reabsorbed by the roller 20. This achieves the purpose of preventing sewage from dripping onto the clean ground and causing secondary pollution to the clean ground.

[0019] It should also be noted that the wastewater recovery assembly 30 also includes a recovery tank 31, which is located on one side of the roller 20 along the radial direction of the roller 20 and is connected to the mounting bracket 10. The recovery tank 31 has a sludge inlet. The scraper 40 can scrape the wastewater on the roller 20 by contacting the outer peripheral surface of the roller 20, and guide the wastewater from the sludge inlet to the recovery tank 31 for storage.

[0020] In some embodiments, the squeegee 40 and the water receiving component 50 can both be connected to the recycling tank 31. The recycling tank 31 is movably connected to the mounting bracket 10, so that the distance between the recycling tank 31 and the roller 20 can be adjusted according to the actual situation. This makes the contact pressure between the squeegee 40 and the water receiving component 50 on the recycling tank 31 and the outer peripheral surface of the roller 20 adjustable to adapt to different cleaning needs and ensure that the best wastewater recycling effect can be maintained under different working conditions.

[0021] In this embodiment, the wiper component 40 is connected to the recovery tank 31. The first end of the wiper component 40 abuts against the roller 20, and the second end extends to the inlet. Therefore, the second end of the wiper component 40 is connected to or tightly fitted against the wall of the inlet to ensure that the wastewater on the wiper component 40 flows smoothly into the recovery tank 31, preventing wastewater overflow. Alternatively, in some embodiments, the wiper component 40 can also be connected to the mounting bracket 10. In this case, the first end of the wiper component 40 abuts against the outer peripheral surface of the roller 20, and the second end extends to the inlet, thereby guiding the wastewater on the roller 20 into the recovery tank 31. In some embodiments, the length of the squeegee 40 and the water-receiving component 50 along the axial direction of the roller 20 is greater than or equal to the length of the roller 20 along the axial direction of the roller 20, so as to ensure that the squeegee 40 and the water-receiving component 50 can effectively contact the outer peripheral surface of the roller 20 throughout the entire length of the roller 20, avoiding cleaning dead corners on the roller 20 due to insufficient length of the squeegee 40. This allows the squeegee 40 to more thoroughly remove sewage from the roller 20, and the water-receiving component 50 to better intercept sewage and prevent dripping, further improving the overall cleaning effect of the cleaning assembly 100.

[0022] Further, please see Figure 3 In some embodiments of this application, on a projection surface parallel to the surface to be cleaned, the orthographic projection of the water-receiving component 50 covers the orthographic projection of the squeegee 40. That is, the length of the water-receiving component 50 along the axial direction of the roller 20 is greater than or equal to the length of the squeegee along the axial direction of the roller 20, and the width of the water-receiving component 50 is greater than or equal to the width of the squeegee 40. The projection of the water-receiving component 50 on the surface to be cleaned can cover the squeegee 40, thereby ensuring that the water-receiving component 50 catches the dripping water on the squeegee 40 as completely as possible, preventing the sewage on the squeegee 40 from dripping onto the clean surface and causing secondary pollution to the clean surface.

[0023] In other embodiments, the wiper component 40 and the water-receiving component 50 can be integrated, with one end of the wiper component 40 and the water-receiving component 50 connected to each other via an arc surface, and the other end respectively abutting against the roller 20. This allows the water-receiving component 50 to completely catch the wastewater dripping from the wiper component 40 and guide it back onto the roller 20. In this case, it is no longer necessary for the orthographic projection of the water-receiving component 50 to completely cover the wiper component 40. The water-receiving component 50 can catch the wastewater dripping from the wiper component 40 through its body and the arc surface connected to the wiper component 40, and guide it back to the roller 20.

[0024] In some embodiments of this application, such as Figures 2-3As shown, the water receiving component 50 has a first side surface 51 facing the roller 20. The first side surface 51 is inclined relative to the surface to be cleaned. The water receiving component 50 is used to receive at least a portion of the wastewater dripping from the squeegee 40 and guide the wastewater to the outer peripheral surface of the roller 20 through the first side surface 51. Specifically, when some wastewater on the roller 20 drips down along the squeegee 40, the water receiving component 50 can intercept the wastewater dripping from the squeegee 40. Due to the inclined arrangement of the first side surface 51 on the water receiving component 50 and the contact between the first end of the water receiving component 50 and the outer peripheral surface of the roller 20, a small amount of wastewater will flow along the inclined first side surface 51 towards the first end of the water receiving component 50. During this flow process, the small amount of wastewater is reabsorbed by the roller 20, thereby preventing wastewater from dripping onto the clean surface.

[0025] It should be noted that when the first side 51 of the water receiving component 50 is inclined, the contact area between the water receiving component 50 and the roller 20 is increased, thereby increasing the contact opportunity between the sewage on the water receiving component 50 and the roller 20. This allows the roller 20 sufficient time to reabsorb the sewage on the water receiving component 50, improving sewage recycling efficiency. Simultaneously, due to the inclined arrangement of the first side 51 of the water receiving component 50, the sewage falling onto the water receiving component 50 will flow along the inclined surface under the action of gravity, thereby reducing sewage stagnation on the surface of the water receiving component 50.

[0026] In some embodiments of this application, the first end of the water receiving member 50 is in elastic contact with the roller 20. It is understood that the first end of the water receiving member 50 can be in close contact with the roller 20, thereby preventing a large gap from forming between the first end of the water receiving member 50 and the roller 20, and preventing sewage dripping from the wiper 40 from dripping onto the ground through the gap between the water receiving member 50 and the roller 20, thereby improving the sewage interception capability of the water receiving member 50.

[0027] The water-receiving component 50 can be an elastic element, allowing it to better adapt to subtle changes in the outer surface of the roller 20 when in contact with it, maintaining a good fit and effectively preventing wastewater dripping. It also avoids potential damage to the outer surface of the roller 20 from hard materials. Furthermore, the elastic material of the water-receiving component 50 can buffer friction with the roller 20 to a certain extent, extending the service life of both the component and the roller 20, and ensuring long-term stable cleaning performance. The elastic element can be made of soft, elastic materials such as silicone or rubber.

[0028] Further, please see Figure 3In some embodiments of this application, at least a portion of the first side surface 51 is configured as a convex arc surface facing the roller 20. It is understood that the convex design of the first side surface 51 can increase the contact area between the water receiving part 50 and the roller 20, further ensuring that sewage can be effectively intercepted during the flow of sewage on the first side surface 51, reducing the possibility of sewage dripping; at the same time, the convex arc surface can make the sewage on the first side surface 51 slide at a slower speed, which is conducive to the sewage on the first side surface 51 being reabsorbed by the roller 20.

[0029] It should be noted that if a small amount of sewage is pressed out by the water receiving part 50 on the roller 20, the convex shape of the first side 51 can also prevent the small amount of sewage pressed out by the water receiving part 50 from dripping directly. The convex shape of the first side 51 causes the small amount of sewage to be pressed out at the highest point of the convexity, and then continues to flow along the shape of the convexity to the lower position of the first side 51, and is gradually reabsorbed by the roller 20 during the flow, thereby reducing the sewage from dripping directly to the ground and causing secondary pollution.

[0030] Please continue reading Figure 3 In some embodiments of this application, the water receiving member 50 has a second side 52 disposed away from the roller 20, and at least a portion of the second side 52 is configured as an arc surface recessed in the direction toward the roller 20.

[0031] Specifically, when the cleaning component 100 is installed on the cleaning robot, the roller 20 faces the ground, and the second side 52 of the water receiving component 50 also faces the ground. Therefore, the recessed design of the second side 52 serves two purposes: firstly, it avoids friction between the water receiving component 50 and the ground or other components; secondly, it prevents wastewater from flowing back from the roller 20 to the recycling tank 31, thus ensuring that as much wastewater as possible is absorbed by the roller 20, reducing the amount of wastewater dripping onto the ground. The second side 52 can also be recessed with a wavy shape to further reduce wastewater backflow.

[0032] Furthermore, such as Figure 3 As shown, the first side 51 and the second side 52 are arranged facing away from each other, and the first side 51 and the second side 52 intersect at the first side edge 53, which abuts against the roller 20. It can be understood that the first side 51 and the second side 52 are connected at the position of the first side edge 53, so that the first side 51 and the second side 52 form a sharp angle. This sharp angle design helps to enhance the guiding performance of the water receiving part 50, concentrate the flow of sewage, reduce the retention of sewage at the edge of the water receiving part 50, and improve the efficiency of sewage being recovered by the roller 20.

[0033] In some embodiments of this application, such as Figures 2-3As shown, the scraper 40 has a scraping surface 41 positioned opposite to the water receiving component 50. Multiple guide strips 411 are arranged on the scraping surface 41 at intervals along the axial direction of the roller 20. It is understood that when there is a large amount of wastewater on the scraping surface 41, the design of multiple guide strips 411 effectively disperses the wastewater, preventing wastewater accumulation and overflow. Multiple water channels are formed between the guide strips 411, allowing the wastewater on the scraping surface 41 to flow more smoothly to the recovery tank 31 under the guidance of these water channels, ensuring that the wastewater is collected quickly and efficiently.

[0034] In some embodiments, a plurality of water guide strips (not shown on the first side 51) are provided on the first side 51 of the water receiving member 50. The plurality of water guide strips are arranged at intervals along the axial direction of the roller 20. Similarly, the design of the plurality of water guide strips can effectively disperse sewage and prevent sewage from accumulating and overflowing. The plurality of water guide strips form a plurality of water guiding channels. Under the guidance of the water guiding channels, the sewage on the first side 51 can flow more smoothly to the surface of the roller 20, ensuring that the sewage is quickly and efficiently reabsorbed by the roller 20.

[0035] Furthermore, such as Figure 3 As shown, the first end of the wiper 40 abuts against the roller 20. The wiper 40 extends at an angle from the second end of the wiper 40 toward the first end and away from the water receiving part 50, so that the sewage scraped off by the wiper 40 from the roller 20 can flow better into the recycling tank 31 along the inclined direction of the wiper surface 41, reducing the sewage retention on the wiper surface 41 and thus improving the sewage collection efficiency.

[0036] In some embodiments of this application, such as Figure 3 As shown, the wiper 40 also has a backwater surface 42 facing the water receiving component 50, and the water receiving component 50 has a first side surface 51 facing the roller 20. The backwater surface 42 and the first side surface 51 are connected by an arc-shaped transition surface 54. It can be understood that the arc-shaped transition surface 54 facilitates the flow of wastewater from the backwater surface 42 along the arc-shaped transition surface 54 to the first side surface 51, and then the first side surface 51 guides the flowing wastewater to the surface of the roller 20.

[0037] At least a portion of the backwater surface 42 is configured as a concave arc surface extending away from the water receiving element 50. This concave design allows wastewater flowing onto the back of the wiper element 40 to quickly slide down the concave arc surface, reducing wastewater retention on the backwater surface 42. Furthermore, when the cleaning assembly 100 stops cleaning and returns to the base station for self-cleaning, the roller 20 can rotate in the opposite direction. At this time, the concave arc surface of the backwater surface 42 helps reduce the frictional resistance between the wiper element 40 and the roller 20. The wiper surface 41 and the backwater surface 42 can be connected by an arc-shaped transition surface. This smooth transition surface reduces friction between the wiper element 40 and the roller 20, thereby extending the service life of both the wiper element 40 and the roller 20.

[0038] Please see Figure 4 In some embodiments of this application, the shortest distance between the axis of the wiper 40 and the axis of the roller 20 is d1, and the shortest distance between the axis of the water receiving component 50 and the axis of the roller 20 is d2, where d2 > d1. That is, the distance between the axis of the wiper 40 and the axis of the roller 20 is smaller, and the interference fit between the wiper 40 and the roller 20 is greater than the interference fit between the water receiving component 50 and the roller 20.

[0039] It is understandable that both the wiper 40 and the water-receiving component 50 are contacting parts that abut against the outer peripheral surface of the roller 20. The smaller the shortest distance between the axis of the roller 20 and the contacting part, the greater the interference fit between the contacting part and the roller 20. An increase in the interference fit will lead to an increase in the pressure of the contacting part on the surface of the roller 20. Since the water-receiving component 50 is used to promote the reabsorption of sewage dripping from the wiper 40 or the roller 20 by the roller 20, and the wiper 40 is used to scrape the sewage off the roller 20, the pressure between the water-receiving component 50 and the roller 20 needs to be less than the pressure between the wiper 40 and the roller 20. Therefore, d1 should be less than d2 to ensure that the water-receiving component 50 can contact the roller 20 to guide the sewage to be reabsorbed by the roller 20, without excessively interfering with the surface of the roller 20 and causing the sewage to be scraped off by the water-receiving component 50.

[0040] Because the interference fit between the wiper 40 and the roller 20 is large, the wiper 40 can remove most of the sewage at that location on the roller 20. At this point, there is less sewage residue at that location, and the water receiving part 50 can more effectively guide the small amount of dripping sewage to be reabsorbed at that location on the roller 20, preventing the sewage on the wiper 40 from dripping onto the clean ground and causing secondary pollution.

[0041] Please see Figures 5-6In some embodiments of this application, a water channel structure 70 is provided on the mounting bracket 10. Multiple spray nozzles 61 are provided on the side of the mounting bracket 10 facing the roller 20. The multiple spray nozzles 61 are arranged at intervals along the axial direction of the roller 20. The water channel structure 70 is used to spray water onto the outer peripheral surface of the roller 20 through the spray nozzles 61, thereby ensuring that the roller 20 is always kept moist and enhancing the cleaning effect. At the same time, the spray nozzles 61 spray water onto the outer peripheral surface of the roller 20, which allows the dirt on the surface of the roller 20 to be fully mixed with water. This makes it easier for the dirt to be scraped off by the squeegee 40 after mixing with the water. This allows the wastewater on the roller 20 to flow quickly to the recycling tank 31 along the water guide channel of the squeegee surface 41, avoiding secondary pollution of the ground by the roller 20 and improving the overall cleaning efficiency.

[0042] In some embodiments, a spray element 60 is provided on the side of the mounting bracket 10 facing the roller 20, and a plurality of spray nozzles 61 are provided on the spray element 60. The side of the spray element 60 facing the roller 20 contacts the outer peripheral surface of the roller 20, or, as... Figure 4 As shown, the side of the spray element 60 facing the roller 20 slightly abuts against the outer peripheral surface of the roller 20. Figure 4 (The roller 20 is not shown to be deformed). That is to say, there is a slight contact pressure between the side of the spraying component 60 facing the roller 20 and the outer peripheral surface of the roller 20. The spraying component 60 contacts or abuts against the roller 20, so that the water sprayed from the spray nozzle 61 can directly cover the surface of the roller 20, preventing water from flowing out from the gap between the spraying component 60 and the roller 20, and improving the spraying efficiency.

[0043] In some embodiments, such as Figures 4-5 As shown, the spray component 60 has a first protrusion 63 extending axially along the roller 20 on its side facing the roller 20, and the first protrusion 63 abuts against the outer peripheral surface of the roller 20. Figure 4 (The deformation of the roller 20 is not shown in the figure) helps to promote the penetration of water from the surface of the roller 20 into the interior of the roller 20, reducing the flow of water on the surface of the roller 20.

[0044] Furthermore, in some embodiments of this application, such as Figures 4-5 As shown, the mounting bracket 10 is provided with a pressing part 13, which abuts against the outer peripheral surface of the roller 20. On the rotation path of the roller 20, the pressing part 13 is located downstream of the spraying component 60.

[0045] Specifically, since the pressure-retaining part 13 is located downstream of the spraying component 60, when the spray nozzle 61 on the spraying component 60 sprays water onto the outer peripheral surface of the roller 20, the pressure-retaining part 13 can promptly press the outer peripheral surface of the roller 20, causing water to penetrate from the surface of the roller 20 into its deeper layers. This ensures that the deeper layers of the roller 20 are also adequately wetted, enhancing the cleaning effect of the roller 20 on the floor. Simultaneously, the pressure-retaining part 13 effectively prevents water sprayed onto the surface of the roller 20 from splashing due to the high-speed rotation of the roller 20.

[0046] In the first rotation direction of the roller 20, the pressing part 13 is located downstream of the spraying member 60, and the squeegee 40 is located downstream of the pressing part 13. For example, taking the outer peripheral surface of the roller 20 as having a first contact part, when the spray nozzle 61 sprays water onto the first contact part, the pressing part 13 first presses the first contact part to ensure that the water fully penetrates. Then, during the rotation of the first contact part of the roller 20 toward the squeegee 40, the water on the first contact part mixes with the dirt to form sewage, so that the squeegee 40 can scrape off the sewage on the first contact part and guide the sewage to the recycling tank 31 through the squeegee surface 41.

[0047] Furthermore, such as Figure 4 As shown, the shortest distance between the wiper component 40 and the axis of the roller 20 is d1, and the shortest distance between the pressing part 13 and the axis of the roller 20 is d3. d3>d1, which means that the distance between the wiper component 40 and the axis of the roller 20 is smaller, and the interference of the wiper component 40 and the roller 20 is greater than the interference of the pressing part 13 and the roller 20.

[0048] It is understandable that both the wiper 40 and the pressure part 13 are contacting components that abut against the outer peripheral surface of the roller 20. The smaller the shortest distance between the axis of the roller 20 and the contacting component, the greater the interference fit between the contacting component and the roller 20. An increase in the interference fit will lead to an increase in the pressure of the contacting component on the surface of the roller 20. Since the pressure part 13 is used to promote the water on the surface of the roller 20 to penetrate into the interior of the roller 20, and the wiper 40 is used to scrape the sewage off the roller 20, the pressure between the pressure part 13 and the roller 20 needs to be less than the pressure between the wiper 40 and the roller 20. Therefore, d1 should be greater than d3 to ensure that the pressure part 13 can effectively promote water penetration without excessively interfering with the surface of the roller 20 and affecting the wiping effect of the wiper 40.

[0049] Please see Figures 6-7In some embodiments of this application, the waterway structure 70 includes a main waterway 71 and at least two branch waterways 72. The main waterway 71 includes at least one branch outlet 711. The branch waterways 72 are connected to the main waterway 71 through the branch outlet 711. The branch waterway 72 has an outlet 721 and is connected to the spray nozzle 61 through the outlet 721. The waterway distance from the branch outlet 711 to the outlet 721 is the same for each branch waterway 72.

[0050] For example, the mounting bracket 10 and the spray component 60 enclose each other to form a water channel structure 70. The mounting bracket 10 is provided with a first water tank 12, and the spray component 60 is provided with a second water tank 62. When the spray component 60 is installed on the mounting bracket 10, the first water tank 12 and the second water tank 62 enclose each other to form a sealed space, which is the water channel structure 70. The mounting bracket 10 is provided with a water inlet hole 11, which is connected to the main water channel 71 so that external water can be introduced through the main water channel 71 and evenly distributed to each spray nozzle 61 through the branch water channel 72, ensuring that the surface of the roller 20 is fully wetted. The sealing design of the water channel structure 70 can prevent water leakage and ensure the stable operation of the water system.

[0051] Among them, such as Figure 7 As shown, at least two or more water channels 72 all begin receiving water from the water inlet 711. The outlet 721 of each water channel 72 is connected to at least one spray nozzle 61. At least two water channels 72 are connected to different spray nozzles 61. The water path distance from the water inlet 711 to the outlet 721 is the same for each water channel 72. This means the path length of the water source in each water channel 72 is consistent, ensuring that the water source reaches the outlet 721 from the water inlet 711 in the same time. This guarantees balanced water pressure at each spray nozzle 61, resulting in uniform water distribution to the surface of the roller 20 and improving the wetting and cleaning efficiency of the roller 20. Furthermore, the outlet 721 of each water channel 72 can be connected to multiple spray nozzles 61, enabling multi-point synchronous spraying and further optimizing the uniformity of wetting the surface of the roller 20.

[0052] Secondly, please see Figure 8 This application also provides a cleaning device 200, including a cleaning body 80 and a cleaning component 100 as described in any of the above embodiments, wherein the cleaning component 100 is disposed on the cleaning body 80.

[0053] in, Figure 8 The cleaning device 200 is shown in cross-section. The roller 20 is located at the bottom of the cleaning body 80 to clean the ground. A wastewater tank can be set in the cleaning body 80 to collect and recycle wastewater in the tank 31. A drive motor is set on the cleaning component 100 to drive the roller 20 to rotate. The cleaning device 200 can be a sweeping and mopping robot or a floor cleaning robot, etc.

[0054] Thirdly, this application also provides a cleaning system (not shown in the figure), including a base station and a cleaning device 200 as described in the above embodiments, the cleaning device 200 being used to interface with the base station.

[0055] Specifically, when the cleaning device 200 is in cleaning operation, the roller 20 rotates in a first rotation direction driven by the drive motor. One full rotation in the first rotation direction is the rotation direction of the roller 20. When the cleaning device 200 returns to the base station for self-cleaning, it connects to the base station. The circuitry in the base station then controls the drive motor, causing it to drive the roller 20 to rotate in a second rotation direction opposite to the first rotation direction. One full rotation in the second rotation direction is the reverse rotation direction of the roller 20. Therefore, the reverse rotation path of the roller 20 is opposite to its rotation path. When the roller 20 is self-cleaning in the base station, this reverse rotation removes dirt and residue from its surface. The self-cleaning function of the roller 20 not only improves cleaning efficiency but also reduces the frequency of manual maintenance, ensuring that the roller 20 maintains optimal cleanliness each time it is used.
