Abstract
Description
Technical Field
[0001] This application belongs to the field of cleaning equipment technology, and specifically provides a control method for a surface cleaning system. Background Technology
[0002] As people's living standards improve, various surface cleaning devices are gradually entering people's daily lives, providing great convenience for cleaning floors, carpets, and other surfaces. These surface cleaning devices generally include cleaning components. In the industry, floor scrubbers typically use cleaning rollers for these components. After cleaning the floor or carpet, the bristles on the cleaning components become dirty, and some of this dirt is thrown out by centrifugal force during rotation and adheres to the side wall of the roller's brush chamber. To facilitate cleaning of the cleaning components, more and more surface cleaning devices are equipped with a tray or base station for cleaning them. When cleaning is needed, the surface cleaning device is placed in the cleaning tank of the base station, and the rotating cleaning components can self-clean. However, this method is ineffective at removing the dirt adhering to the side wall of the roller's brush chamber.
[0003] Existing technologies propose a method where the sidewall of the brush cavity is configured to make interference contact with the brush, allowing the cleaning roller to wipe away dirt on the sidewall in real time. This method results in high contact friction between the cleaning roller and the sidewall of the brush cavity, leading to increased brush current and affecting motor operation, or requiring a higher torque motor, thus increasing costs. Another proposed solution involves a drive device within the brush. During self-cleaning, this device moves or rotates the brush cover, causing it to contact the sidewall of the brush cavity with the brush surface for automatic cleaning. However, this method requires an additional drive device to operate the brush cover, increasing costs and placing higher demands on the reliability of the transmission structure. Summary of the Invention
[0004] To address the aforementioned problems in the prior art, this application provides a control method for a surface cleaning system that, compared to the prior art, enables automatic cleaning of the roller brush cavity.
[0005] The surface cleaning system described in this application includes a floor brush with cleaning components and a base with a cleaning tank. The cleaning components are installed inside the roller brush cavity of the floor brush. The floor brush is placed on the base so that the cleaning components self-clean within the cleaning tank. The control method includes a floor cleaning step and a roller brush cavity cleaning step.
[0006] The floor cleaning steps include: the cleaning component rotates forward, the bristles on the cleaning component absorb water and lie flat on the surface of the cleaning component under the scraping action of the scraping component;
[0007] The roller brush cavity cleaning steps include sub-step B: the cleaning component is reversed, and the scraping component scrapes the bristles to make the bristles stand up and wipe the roller brush cavity.
[0008] Preferably, the self-cleaning method further includes:
[0009] Cleaning steps for cleaning parts: The cleaning parts are rotated forward, and the bristles on the cleaning parts absorb water and lie flat under the action of the scraping parts.
[0010] Preferably, in the cleaning step of the cleaning component, the bristles absorb water, lie flat, and form a gap between the cleaning component and the roller brush cavity.
[0011] Preferably, the roller brush chamber step includes a sub-step A before sub-step B: stopping the supply of cleaning fluid to the cleaning component.
[0012] Preferably, between sub-step A and sub-step B, there is also a time T3 in which the cleaning component rotates forward at a third speed.
[0013] Preferably, after step B, a sub-step C is included: the cleaning component rotates forward so that the raised bristles wipe the roller brush cavity.
[0014] Preferably, the B sub-step and the C sub-step are performed alternately.
[0015] Preferably, a suction port is provided on one side of the roller brush cavity, and the suction port is connected to a vacuum fan. During the roller brush cavity cleaning step, the suction fan keeps working; or, the B sub-step and / or C sub-step operate intermittently or continuously.
[0016] Preferably, the floor brush is further provided with a drive device, which is connected to the scraper to drive and control the interference between the scraper and the cleaning chamber. In sub-step B of the roller brush chamber cleaning step, the drive device is controlled to move the scraper so that there is a gap between the scraper and the bristles or to reduce the interference between the scraper and the bristles, and the cleaning chamber is controlled to reverse.
[0017] Preferably, the floor cleaning step further includes: adding at least one reverse rotation process to the cleaning component during the forward rotation.
[0018] The beneficial effects of adopting the above technical solution include:
[0019] First, the self-cleaning process cleans the cleaning rollers first, then the first surface of the roller brush cavity. Compared to cleaning the roller brush cavity first, this avoids secondary contamination caused by dirt being thrown off the first surface by the centrifugal force of the roller brush during the cleaning process. Furthermore, during the roller brush self-cleaning process, the water distribution plate continuously or intermittently supplies cleaning fluid to the cleaning components. Some of the cleaning water is thrown off by centrifugal force onto the first surface of the roller brush cavity during the cleaning process, thus wetting the dirt. Subsequent impact from the thrown-off cleaning fluid can partially wash away the dirt adhering to the roller brush cavity.
[0020] Secondly, during the reversal of the cleaning component, the bristles are significantly reduced in moisture content due to the reverse scraping by the scraping component during the automatic cleaning process. With a certain moisture content, the bristles will subsequently clump together and / or stand upright in rows during the reversal process. These upright bristles then wipe and clean the first surface of the roller brush cavity. Compared to the prior art mentioned in the background section, this method achieves automatic cleaning of the roller brush cavity without requiring the roller brush cover to move.

[0035] It should be noted that the surface cleaning device in this embodiment can be a handheld cleaning machine with a handle that is manually operated by the user, such as a handheld floor scrubber, handheld floor mop, or handheld vacuum cleaner. It can also be a self-moving cleaning robot with drive wheels, which can control the drive wheels to move according to its stored program and control the mop assembly to clean the floor.
[0036] The following explanation uses a handheld surface cleaning device as an example.
[0037] Example 1:
[0038] like Figures 1 to 7As shown, the surface cleaning system of the present invention includes a surface cleaning device 10 and a base 20 for placing and cleaning the surface cleaning device 10. The surface cleaning device 10 includes a body 11 and a floor brush 12 connected to the body. The floor brush 12 includes a floor brush housing 121 with a roller brush cavity, a cleaning component 122, a water distribution plate 123, a dirt extraction assembly, and a roller brush cover 126. The roller brush cover 126 and the floor brush housing 121 together form a roller brush cavity for accommodating the cleaning component 122. The floor brush housing 121 is provided with a floor brush motor (not shown) for driving the cleaning component to rotate. The roller brush cover 126 has... The inner surface 1261 forms part of the roller brush cavity. The cleaning component 122 is rotatably disposed within the roller brush cavity 1211. The cleaning component 122 includes a roller 1221 disposed within the roller brush cavity and a mop 1222 wound around the outer surface of the roller 1221. The mop 1222 includes a substrate 1222a and bristles 1222b located on the substrate 1222a. The bristles 1222b are supported by fibers or other materials with water absorption properties. The substrate is adhered to the surface of the roller 1221. When the bristles 1222b on the cleaning component 122 are not absorbing water, they are fluffy and most of the bristles stand up. The surface cleaning device also has a clean water tank 113 and a water pump (not shown in the figure) on the floor brush or body. The clean water tank 113, the water pump, and the water distribution plate 123 are connected in sequence through pipelines to provide cleaning fluid to the cleaning component. The floor brush 12 is also equipped with a scraping component 125 for scraping and cleaning the bristles 1222b on the cleaning component 122. The base 20 has a cleaning groove 21. The cleaning component 122 is placed inside the cleaning groove 21 with a gap between it and the groove wall. The cleaning component 122 rotates, and the water distribution plate 123 provides cleaning fluid to the cleaning component or the cleaning groove 21 to wet the bristles or the surface to be cleaned. The cleaning component 122 moves along the attached... Figure 2 When the plane shown rotates counterclockwise, the scraping component 125 scrapes and cleans the bristles 1222b on the cleaning component 122. The sludge suction assembly also includes a sludge suction port 124 located on one side of the roller brush cavity, a sludge suction motor 111 located in the machine body 11, and a sludge collection tank 112. The sludge suction port 124 is connected in sequence to the sewage tank 11 and the vacuum blower 111. The sludge suction port 124, the sewage tank 112, and the sludge suction motor 111 are connected by a pipeline so that the sludge scraped off by the scraping component 125 is sucked into the sewage tank 112 through the pipeline.
[0039] In this embodiment, the sidewall of the roller brush cavity is provided with a first surface 1211a opposite to the cleaning component. The first surface 1211a has a shape corresponding to the outer contour of the roller brush. The distance between the first surface 1211a and the outer surface of the substrate 1222a is less than the length of the bristles. That is, when the bristles 1222b are upright, the ends of the bristles 1222b are in contact with the first surface 1211a. It can be understood that when the bristles of the roller brush are in a fluffy state without absorbing water, the bristles are also in contact with or abutting against the first surface 1211a.
[0040] It is understood that the first surface 1211a may be part of or the entire inner surface 1261 of the roller brush cover; the cleaning component may be a roller structure or a tracked annular cleaning belt structure as disclosed in the applicant's patent CN202310119732.1.
[0041] It should be added that we attach... Figure 2 Alternatively, using the plane direction shown in Figure 5 as a reference, rotating the cleaning component counterclockwise is considered forward rotation, and rotating it clockwise is considered reverse rotation. When the surface cleaning device performs its cleaning operation, to ensure the performance of the drive motor and the cleaning effect of the surface cleaning device, and to reduce the power consumption of the surface cleaning device, we set the drive motor to rotate forward most of the time. Of course, it is understandable that we can also make the opposite setting; for example, during the cleaning step, the cleaning component can be positioned as shown in the attached figure of this embodiment. Figure 2 Using the plane shown as a reference, rotate the cleaning component clockwise; during the roller brush chamber cleaning step, rotate the cleaning component counterclockwise.
[0042] The surface cleaning device of this embodiment can operate according to the following procedure when cleaning the surface to be cleaned:
[0043] The water distribution plate 123 supplies liquid, and the cleaning component 122 rotates clockwise. The bristles 1222b on the cleaning component 122 are wetted. The scraping component 125 squeezes and scrapes the bristles 1222b on the cleaning component. After a certain period of time, the water-absorbing bristles 1222b, under the repeated action of the scraping component 125, lie flat on the surface of the cleaning component 122 in the direction shown in the figure, so that there is a gap between the bristles 1222b and the first surface 1211a and they no longer contact each other. At the same time, the bristles on the cleaning component continuously clean the surface to be cleaned. The dirt and / or liquid scraped off by the scraping component 125 are sucked into the sludge container 112 through the suction port 124 by the suction motor 111. The cleaning component 122 rotates clockwise for a certain period of time to complete the cleaning of the surface to be cleaned. The state of the bristles on the cleaning component when the aforementioned surface cleaning device cleans the surface to be cleaned can be referred to Figure 2 , 3 The self-cleaning process status of the cleaning components in section 4.
[0044] Understandably, we can also add at least one reverse rotation process of the cleaning component during the cleaning process of the surface cleaning device, that is, during the forward rotation of the cleaning component. The reverse rotation time is shorter than the forward rotation time. This can further improve the cleaning effect of the surface cleaning device. This concept, which does not depart from the technical solution of this invention, is also within the protection scope of this solution, and will not be listed in detail here.
[0045] When automatic cleaning of the surface cleaning device is required, the operation process of the control method of the surface cleaning system is as follows: The surface cleaning device is placed on the base so that the cleaning component is in the cleaning tank. The surface cleaning device stops moving, and the automatic cleaning function button of the surface cleaning system is activated, thus starting the automatic cleaning operation.
[0046] Cleaning steps for cleaning parts: Figure 2 , 3 As shown in Figure 4, the water distribution plate 123 provides cleaning fluid to the cleaning component. The cleaning component 122 rotates in the first direction at a first speed V1 for a time T1. During this process, the bristles on the roller brush absorb the cleaning component and are scraped by the scraping component 125 to remove dirt, which is then sucked away by the suction motor through the suction port. Simultaneously, the bristles 1222b on the roller brush expand due to water absorption and, under the continuous scraping action in one direction by the scraping component for time T1, lie flat as shown in the figure, forming a layer between the cleaning component and the first surface 1211a. Figure 4 The gap shown indicates that the hair tuft 1222 is not in contact with the first surface 1211a because it is flattened.
[0047] Roller brush chamber cleaning steps: as follows Figure 5 , 6 As shown in Figure 7, the process includes sub-step B: the cleaning component 122 rotates at a second speed V2 in a second direction for a time T2, the bristles are dispersed by the scraping component, and rise from the outer surface of the cleaning component to wipe the first surface. (See Figure 7 for details.) Figure 6 As shown, the fallen bristles stand up under the action of the scraping element 125; as Figure 7 As shown, the raised bristles come into contact with and scrape the surface of the first surface 1211a as the cleaning component rotates in the second direction, thereby wiping away the dirt adhering to the first surface 1211a and thus cleaning the first surface.
[0048] First, in the self-cleaning step, the cleaning roller is cleaned first, and then the first surface of the roller brush chamber is cleaned. Compared with cleaning the roller brush chamber first, it can avoid secondary contamination caused by dirt being thrown out by the centrifugal force of the roller brush and adhering to the first surface during the cleaning process of the cleaning roller. Moreover, during the self-cleaning process of the roller brush, the water dividing plate continuously or intermittently supplies cleaning liquid to the cleaning part. Part of the cleaning water is thrown out by the centrifugal force during the cleaning process of the roller brush to the first surface of the roller brush chamber, thereby wetting the dirt. Under the impact of the subsequent thrown-out cleaning, part of the dirt adhering to the roller brush chamber can be washed away.
[0049] Secondly, during the reverse rotation of the cleaning part, since the cleaning part is automatically cleaned during rotation, the water content of the hair clusters is greatly reduced after being reversely scraped by the scraping part. When the hair clusters with a certain water content rotate reversely subsequently, the hair clusters will form local adhesions and stand up in bundles and / or rows. These standing hair clusters wipe and clean the first surface of the roller brush chamber during the reverse rotation. Compared with the prior art mentioned in the background art, it can achieve automatic cleaning of the roller brush chamber without driving the roller brush cover to move.
[0050] It can be understood that in the cleaning step of the cleaning part, the cleaning liquid can also be indirectly supplied to the cleaning part by directly supplying the cleaning liquid from the water tank on the base to the cleaning tank; the first speed V1 is not a fixed value, but a numerical range. For example, the range of the first speed V1 can be 200 rpm to 250 rpm, and the range of the second speed V2 can be 180 rpm to 220 rpm. The same applies to V3 and V4 mentioned in the subsequent embodiments, which will not be elaborated here.
[0051] Furthermore, the rotational speed V1 of the cleaning part in the first direction during the roller brush cleaning step is greater than the rotational speed in the second direction during the first surface cleaning step, that is, V2 < V1. For example, the range of the first speed V1 can be 200 rpm to 250 rpm, and the range of the second speed V2 can be 150 rpm to 190 rpm. In the roller brush cleaning step, the roller brush rotates at the first speed V1. The relatively high speed results in a greater centrifugal force of the cleaning liquid on the roller brush. The greater centrifugal force can make more cleaning liquid be thrown out and obtain a greater impact force, thereby enhancing the wetting and scouring effects. In the first surface cleaning step, the roller brush runs at a relatively low second speed, and the centrifugal force on the hair clusters on the roller brush is relatively small, so the hair clusters can better maintain the standing state, thereby enhancing the wiping effect on the first surface.
[0052] Embodiment 2:
[0053] In this embodiment, to further improve the wiping effect of the bristles on the cleaning component on the first surface, a sub-step A is included before sub-step B in the roller brush chamber cleaning step: stopping the supply of cleaning fluid to the cleaning component or supplying fluid at a flow rate lower than that in the cleaning component cleaning step. In this embodiment, it is preferable to control the water distribution plate 123 to stop the fluid supply.
[0054] During the automatic cleaning process of the rotating cleaning unit, the bristles contain a large amount of moisture. After repeated scraping by the scraping components, the bristles stick together. Even after the suction process reduces the moisture content significantly, the bristles remain damp due to centrifugal force and the scraping components, thus remaining tightly adhered to the wall of the cleaning unit along its rotation direction. At this point, the water distribution plate stops supplying liquid, preventing the bristles from further increasing in moisture content. During the subsequent reverse rotation, the bristles, with a certain moisture content, will partially stick together to form bundles or rows that stand upright. These bristles have better strength when in contact with the first surface, resulting in greater wiping force and ensuring effective cleaning. If cleaning fluid continues to be supplied to the cleaning unit at this point, some of the cleaning fluid will diffuse into the upright bristle area under the action of the suction fan or centrifugal force, leading to insufficient strength in these upright bristles and poor wiping effect on the first surface.
[0055] In one specific embodiment, the suction fan remains operational during sub-steps A and B of the roller brush chamber cleaning step.
[0056] In another specific embodiment, the suction fan stops working in sub-steps A and B. This achieves energy saving and reduces machine noise, and also avoids the increased overall load on the surface cleaning device caused by the increased resistance during the reverse rotation of the cleaning components, which would lead to an increase in the power of the roller brush motor and thus protect the electrical components.
[0057] Furthermore, between the sub-steps A and B, there is also a time T3 during which the cleaning component rotates in the first direction at a third speed V3.
[0058] After the water distribution plate stops supplying liquid, the cleaning component is first controlled to continue rotating in the first direction at the third speed V3 for a time T3. This allows the scraping component to scrape off excess cleaning liquid from the brush bristles, maintaining the moisture content of the bristles within a certain range. On the one hand, this reduces the time spent in reverse rotation during the first direction of the cleaning component, reducing the possibility of excessive resistance in the brush motor during the reverse rotation, which could lead to excessive temperature rise in the brush motor. On the other hand, with a certain moisture content, the bristles will form localized adhesion and stand up in bundles or rows during the subsequent reverse rotation, enhancing the wiping and cleaning ability of the standing bristles on the first surface.
[0059] Specifically, during the time T3 that the cleaning component rotates in the first direction at a third speed V3, the suction fan remains on to remove the dirt or liquid that has been scraped off by the cleaning component.
[0060] Example 3:
[0061] The difference between this embodiment and the previous embodiment is that, after the B sub-step, there is also a C sub-step: the cleaning component rotates in the first direction at a fourth speed V4 for a time T4, so that the raised bristles wipe the first surface.
[0062] In sub-step B, the cleaning component rotates in the second direction, and the raised bristles wipe the first surface to transfer dirt from the first surface to the bristles and move it towards the scraper. This may result in a small portion of the dirt not being removed by the suction fan. Therefore, after sub-step B, the cleaning component is controlled to rotate in the first direction at a fourth speed V4 for a time T4, so that the dirt on the bristles can be scraped off by the scraper during the rotation of the cleaning component in the first direction.
[0063] Furthermore, in sub-steps B and C, the suction fan remains operational. Specifically, the suction fan can operate intermittently or continuously in sub-steps B or C. Preferably, the actual power of the suction fan in the first surface cleaning step is less than that in the cleaning part cleaning step, because the amount of dirt is relatively small at this time, so there is no need to use high power, and at the same time, it can reduce the fan noise in the working chamber.
[0064] Furthermore, in step C, the water distribution plate starts supplying liquid, and as the cleaning component rotates in the first direction at the fourth speed, the cleaning liquid is thrown onto the first surface, thereby performing a final rinse on the first surface to ensure that the dirt on the first surface is completely removed.
[0065] Furthermore, a roller brush with a certain moisture content, during its rotation in either the first or second direction, will cause the upright bristles to lie flat again in a certain direction after rubbing against the scraping element for a certain period of time. Therefore, alternating between sub-steps B and C ensures that the upright bristles continuously wipe the first surface in both directions during sub-steps B and C, further improving the cleaning effect. Alternatively, it can be understood that the cleaning element can be controlled to rotate in the second direction by a first angle during sub-step B, and then controlled to rotate in the first direction by a second angle during sub-step C. The relative sizes of the first and second angles can be set according to actual needs.
[0066] Example 4:
[0067] In this embodiment, the floor brush is equipped with a drive device (not shown in the figure). The drive device is connected to the scraping component to drive and control the interference fit between the scraping component and the cleaning component. It can be understood that the drive device can be an electric drive device such as a motor, or it can be driven by an external user.
[0068] As a specific embodiment, in the cleaning step, the scraper and the cleaning part are kept in an interference fit. Between sub-steps B and C of the roller brush cavity cleaning step, the step of controlling the drive device to move the scraper is further included, so that there is a gap between the scraper and the bristles of the cleaning part, or, compared to the cleaning step, the interference fit between the scraper and the bristles of the cleaning part is reduced.
[0069] As a specific embodiment, in the cleaning step, the scraper and the cleaning component maintain an interference fit. In sub-step B of the roller brush chamber cleaning step, after controlling the cleaning component to rotate in the second direction for time t1, the drive device is controlled to move the scraper, creating a gap between the scraper and the bristles of the cleaning component, or reducing the interference fit between the scraper and the bristles of the cleaning component compared to the cleaning step. Then, the cleaning component continues to rotate in the second direction for time t2. It is understood that when the drive device moves the scraper, the cleaning component may be stopped or remain rotating.
[0070] By controlling the movement of the scraper and maintaining a gap between it and the bristles during the roller brush chamber cleaning step, or by reducing the interference between the scraper and the bristles of the cleaning component compared to the cleaning component cleaning step, the effect of the scraper on the bristles erected during the roller brush chamber cleaning step can be improved, thereby enhancing its wiping effect on the first surface.
[0071] Example 5:
[0072] like Figure 8 As shown, the difference between this embodiment and the previous embodiment is that the first surface 1211a is disposed on the floor brush housing. In this embodiment, the surface of the water-dividing plate 123 opposite to the cleaning component is an arc-shaped surface. The water-dividing plate 123 is provided with a water supply port 1232. The arc-shaped surface forms the first surface 1211a. During the cleaning process of the cleaning component rotating in the first direction, the bristles absorb water and lie flat under the action of the scraping component, forming a gap between the cleaning component and the first surface. During the cleaning process of the cleaning component rotating in the second direction, the water-dividing plate stops supplying liquid, and the scraping component scrapes the bristles to make the bristles stand up and wipe the first surface. In this way, the cleaning component can wipe and clean the arc-shaped surface of the water-dividing plate.
[0073] Example 6:
[0074] The difference between this embodiment and the previous embodiment is that: the floor brush includes a roller brush cover and a floor brush housing. The roller brush cover is detachably installed on the floor brush housing. The floor brush housing is provided with a first connector that communicates with a water pump. The water distribution plate is provided on the roller brush cover. The roller brush cover is provided with a second connector that communicates with the water distribution plate. When the roller brush cover is installed on the floor brush housing, the first connector and the second connector communicate to provide cleaning fluid to the water distribution plate. The inner side of the water distribution plate opposite to the cleaning component and the inner side of the roller brush cover opposite to the cleaning component together form the first surface.
[0075] Example 7:
[0076] The difference between this embodiment and embodiment five is that: the floor brush housing 121 is also provided with a floor scraper 1213, the floor scraper 121 is located below the suction port 124, the front side of the top of the floor brush housing 121 is provided with a first step portion 1212, the first step portion 1212 includes a first step portion step surface 1212b and a first step portion sidewall 1212a, a limiting portion 1212c is provided at the first step portion 1212, one end of the roller brush cover 126 is engaged with the limiting portion for locking, wherein the top of the cleaning component 122 is higher than the step surface 1212b of the first step portion 1212.
[0077] It should be noted that the top of the cleaning part 122 being higher than the step surface 1212b of the first step portion 1212 means that when the hair tuft is in a fluffy state without absorbing water, the hair tuft is higher than the step surface 1212b of the first step portion 1212.
[0078] Figure 11 The dashed line L1 indicates the height position of the step surface 1212b of the first step 1212, and the dashed line L2 indicates the highest position of the bristles 320 on the top side of the cleaning part 122 in a fluffy state.
[0079] Because the top of the cleaning component is higher than the step surface 1212b of the first step 1212, the height of the roller brush cover 126 relative to the cleaning component 122 can be lowered, thereby reasonably reducing the overall thickness of the floor brush 10 and enabling an ultra-thin structure. When the surface cleaning device is in operation, the floor brush can access low spaces such as under beds, cabinets, and sofas for cleaning, allowing the surface cleaning device to better meet the user's cleaning needs and improve the user experience.
[0080] Combination Figure 11 The distance H1 between the axis of the cleaning component and the bottom surface of the floor brush housing is less than the distance H2 between the axis of the roller brush cleaning component and the step surface 1212b of the first step 1212. This allows the roller brush to effectively wipe the surface to be cleaned while reasonably controlling the radial dimension of the cleaning component, which is conducive to further reasonably reducing the overall thickness of the floor brush and enabling the floor brush to achieve an ultra-thin structure.
[0081] In order to avoid rotational interference between the floor scraper 170 and the roller brush 300 while appropriately reducing the outer diameter of the cleaning part, the projection of the leading edge of the first step portion 1212 in the vertical direction is located in front of the floor scraper 170. Figure 11 In the diagram, line L4 represents the vertical direction of the leading edge of the first step 110, and line L5 represents the vertical direction of the leading edge of the ground scraper 170 in its free state. Line L4 is located in front of line L5.
[0082] Combination Figure 10 , Figure 11 The front end of the water-dividing plate 123 extends forward to the front edge of the first step portion 1212. In this embodiment, the arc surface 151 is concentrically arranged with the roller brush 300. The front end of the water-dividing plate 123 is provided with a plane that connects with the top side of the arc surface. This plane is aligned with the front edge of the first step portion 1212.
[0083] Combination Figure 10 The distance S1 between the water supply hole 1232 and the scraper 125 on the arc-shaped surface is less than the distance S2 between the water supply hole 152 and the front end of the water distribution plate 123. Reasonably increasing the effective water distribution path length of the arc-shaped surface to the cleaning component is beneficial to further improving the water distribution effect of the arc-shaped surface to the cleaning component.
