Description

Technical Field

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

[0002] With the development of pool cleaning technology, pool cleaning robots have gradually emerged. Existing pool cleaning robots can suck up dirt through the inlet at the bottom of the machine.

[0003] In actual use, due to the large gap between the inlet and the surface to be cleaned, water can enter the inlet from all directions. As a result, the suction force is dispersed due to the multiple directions of water inlet, resulting in low efficiency in the suction of dirt and affecting the effective suction of dirt. Summary of the Invention

Each cleaning group includes several cleaning ribs that are spaced apart along the circumferential direction of the cleaning body.

[0025] In one possible implementation, the arrangement path of the plurality of cleaning ribs belonging to the same cleaning group is a spiral extending around the axis of the cleaning body.

[0068] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0069] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0070] With the development of pool cleaning technology, pool cleaning robots have gradually emerged. Existing pool cleaning robots can suck up dirt through the inlet at the bottom of the machine.

[0071] In actual use, traditional pool cleaning robots usually need to keep their bottom a certain distance from the bottom of the pool in order to improve obstacle avoidance. The higher the distance, the better the obstacle avoidance effect. Therefore, there is often a large gap between the sewage inlet and the surface to be cleaned.

[0072] Because of the large gap between the inlet and the surface to be cleaned, and the excessive height of the inlet, the bottom inlet is too high above the pool bottom. This allows water to enter from all directions, making it difficult to create a stable negative pressure near the inlet. Multiple water intakes disperse the suction force, and water from the rear carries away some of the suction, resulting in low efficiency in removing debris and hindering effective debris removal. In particular, when dealing with larger floating objects such as leaves, the dispersed suction force often results in pushing rather than sucking them in. Furthermore, the water flow velocity below the inlet in traditional designs is insufficient to create effective negative pressure, limiting the cleaning effect.

[0073] In view of this, the present application provides a cleaning device and a cleaning system. By designing a first cleaning component to actively lift dirt, coordinating the positional relationship between the first and second areas, and combining the synergistic mechanism of the suction device to concentrate dirt suction, the flow velocity in front of the suction port is increased, forming a local high pressure differential area, thereby enhancing the adsorption capacity of the lifted dirt.

[0074] The scheme is described in detail below with reference to the accompanying drawings. Here, x can be the first direction, and y can be the second direction.

[0075] This embodiment provides a cleaning device 10, which can be used to perform cleaning, disinfection, rescue, and other tasks in a target area. The target area can be a water-containing area where the cleaning device 10 can move. The target area is not limited to swimming pools, ponds, oil wells, sewers, etc. The following description uses a pond as an example. The cleaning device 10 is suitable for operation in the water of a pond. For example, the cleaning device 10 is a swimming pool cleaning robot.

[0076] Combination Figures 1 to 6 The cleaning device 10 includes a housing 100, a filter device 210, a suction device 220, a walking device 300, and a first cleaning component 400.

[0077] Reference Figure 2 , Figures 5 to 7 The housing 100 has a filter channel 101 formed inside it. The housing 100 includes a bottom shell 110, and the bottom shell 110 has a dirt inlet 111 that communicates with the filter channel 101. The bottom shell 110 includes a first region 112 and a second region 113 distributed along a first direction. The distance between the first region 112 and the surface to be cleaned is smaller than the distance between the second region 113 and the surface to be cleaned. The dirt inlet 111 is located in the first region 112.

[0078] Reference Figure 5 and Figure 6 The filter device 210 is located in the filter channel 101 and is used to filter the fluid; the suction device 220 is located in the filter channel 101 and is used to drive the fluid from the inlet 111 into the filter channel 101 and then through the filter device 210 before being discharged.

[0079] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The walking device 300 is located at the bottom of the housing 100, and the cleaning device 10 moves along the surface to be cleaned via the walking device 300; the first cleaning component 400 is located at the bottom of the housing 100 and is located on the side of the inlet 111 along the first direction (i.e., the x direction). The first cleaning component 400 is used to lift up the dirt attached to the surface to be cleaned so as to suck it into the filter channel 101.

[0080] Optionally, the first direction (i.e., the x-direction) can be the direction of travel of the cleaning device 10.

[0081] Optionally, the housing 100 may also have a water outlet 102 for filtered water to flow out.

[0082] The housing 100 can serve as a support structure for the internal components, and a filter channel 101 is formed inside, communicating with the inlet 111. The filter device 210 can be used to intercept impurities in the water; optionally, the filter device 210 can adopt a multi-layer filter structure. The suction device 220 can be a power source for generating negative pressure; optionally, the suction device 220 can be a centrifugal water pump, axial flow pump, etc., which drives the water flow from the inlet 111 through impeller rotation.

[0083] Optional, see reference Figure 18 The housing 100 has an internal cavity that connects to the inlet 111. The filter device 210 is positioned near the center of the cavity. The filter device 210 includes a first filter cover 211 and a second filter cover 212. The suction device 220 includes a motor, an impeller 222, and an impeller cover 221. The impeller cover 221 covers the impeller 222. The main body of the motor is sealed inside the control box. The output shaft extends into the impeller cover 221 and connects to the impeller 222. One end of the impeller cover 221 can form the water inlet of the suction device 220, and the other end can communicate with the outlet 102. The first filter cover 211 covers the impeller cover 221, and the second filter cover 212 is located outside the first filter cover 211. The second filter cover 212 can be placed on the inner wall of the cavity. The second filter cover 212 is spaced apart from the inner wall of the cavity. The first filter cover 211 and the second filter cover 212 together form a filter channel 101.

[0084] Specifically, taking a water tank as an example, when the cleaning device 10 is working at the bottom of the tank, the water carrying dirt enters the filter channel 101 from the inlet 111 and has at least two flow paths.

[0085] In one path, water flows into the filter channel 101 from the inlet 111 and passes through the second filter cover 212. During this process, impurities are trapped in the filter channel 101 by the second filter cover 212, while the filtered water flows into the gap between the second filter cover 212 and the inner wall of the receiving cavity. Then, under the suction action of the suction device 220, it enters the water inlet of the suction device 220 and is finally discharged from the housing 100 through the outlet 102.

[0086] In another path, after the water flows into the filter channel 101 from the inlet 111, it passes through the first filter cover 211. During this process, impurities are trapped in the filter channel 101 by the first filter cover 211, while the filtered water can pass through the first filter cover 211 under the suction action of the suction device 220. During this process, most of the water flows to the inlet of the suction device 220 and is finally discharged from the housing 100 through the outlet 102.

[0087] Optionally, the walking device 300 may be a tracked or wheeled structure to drive the housing 100 to move on the surface to be cleaned. Optionally, the first cleaning component 400 may be a rotating roller brush, which removes adhering dirt by contacting the bristles with the surface to be cleaned.

[0088] Specifically, when the cleaning device 10 moves along the first direction, the first cleaning component 400 rotates continuously. The first cleaning component 400 first comes into contact with the dirt, physically peels off, stirs and lifts the dirt attached to the surface to be cleaned, suspending it in the water, thereby converting the attached dirt that is difficult to be directly sucked into the suspended dirt that is easy to move with the water flow. At this time, the suction device 220 operates to generate negative pressure, driving the water flow to carry the dirt from the dirt inlet 111 into the filter channel 101.

[0089] The smaller distance between the first region 112 and the surface to be cleaned means that the water flow channel below the first region 112 is narrower. According to the principles of fluid dynamics, under the same power of the suction device 220, the water flow velocity in this narrow channel will be significantly higher than that in the second region 113, which has a larger distance. Thus, the higher flow velocity can generate stronger local suction near the inlet 111, thereby greatly improving the efficiency of capturing and sucking up dirt.

[0090] In addition, the smaller gap between the first area 112 and the surface to be cleaned limits the possibility of dirt escaping from its bottom and enhances the dirt collection effect. The larger gap between the second area 113 and the surface to be cleaned provides tolerance space for the movement of the cleaning device 10 and also increases the space for dirt to accumulate.

[0091] As can be seen, compared with the existing technology, the free flow of water behind the inlet of traditional cleaning equipment leads to the dispersion of suction. This solution designs the first cleaning component 400 to actively lift the dirt, and combines the positional relationship design of the first area 112 and the second area 113 with the synergistic mechanism of the suction device 220 to concentrate the dirt suction, so as to increase the flow velocity in front of the suction port, form a local high pressure difference area, and enhance the adsorption capacity of the lifted dirt.

[0092] Reference Figure 2 The cleaning device 10 also includes a scraper 500, which is disposed on the bottom shell 110. At least a portion of the scraper 500 is disposed on the side of the inlet 111 facing away from the first cleaning component 400 and adjacent to the inlet 111.

[0093] The scraper 500 is a flow guiding structure. Optionally, the scraper 500 can be made of flexible rubber, and part of its structure can extend to the area behind the sewage inlet 111. It can block the water flow behind and guide the sewage in front to gather towards the sewage inlet 111.

[0094] Specifically, the scraper 500 is positioned near the rear of the inlet 111 to prevent water from flowing directly into the suction port from the rear area of ​​the cleaning device 10, forcing most of the water to flow in from the working area of ​​the first cleaning component 400 on the front side; finally, the water carrying dirt enters the filter channel 101 inside the housing 100, and after the filter device 210 intercepts solid particles, the clean water is discharged, completing the entire cleaning cycle.

[0095] In this way, the scraper 500 forms a semi-enclosed space with the bottom shell 110, which realizes the dilution and collection, and prevents the adsorbed dirt from escaping due to water flow disturbance. This improves the suction efficiency of dirt and enhances the concentration of suction.

[0096] For reference Figure 18 The housing 100 may also be provided with a water outlet 102. During operation, water mixed with impurities is drawn into the filter channel 101 from the inlet 111. The filter device 210 in the channel intercepts the impurities in the water, and the clean water is finally discharged from the housing 100 from the outlet 102. The direction of water flow can be seen in the figure.

[0097] In addition, the housing 100 may be provided with multiple water passages 115, which are suitable for balancing the water pressure on the inside and outside of the housing 100 and realizing the rapid flow of water. When the cleaning device 10 is placed in the water, the water can quickly enter the interior of the housing 100 through the water passages 115, expelling air and helping the cleaning device 10 to quickly overcome buoyancy and sink; when the cleaning is completed and the cleaning device 10 is lifted out of the water, the water contained in the cavity inside the housing 100 can be quickly discharged through the water passages 115, avoiding the carrying out of a large amount of pool water, and facilitating the collection and transportation of the cleaning device 10.

[0098] In some embodiments, refer to Figure 19 The housing 100 may also have a sludge collection port 103 on the side wall in the first direction (i.e., the x direction). In some situations, the cleaning device 10 needs to clean impurities on the water surface. The cleaning device 10 will float on the water surface and open the sludge collection port 103 on the side wall of the housing 100 (at this time, the sludge inlet 111 on the bottom shell 110 can be closed).

[0099] Optional, see reference Figure 21 The length direction of the sewage collection port 103 can be the second direction (i.e., the y direction), and the housing 100 can also be provided with a driver 120 on both sides of the sewage collection port 103 in the second direction.

[0100] When the cleaning device 10 floats on the water surface, the driver 120 can drive the cleaning device 10 to move towards the impurities on the water surface, so that the impurities can naturally enter the housing 100 through the collection port 103. Combined with the suction generated by the suction device 220, the floating objects such as leaves and dust are finally sucked into the filter channel 101. After the filter device 210 in the channel intercepts the impurities in the water, the clean water is finally discharged from the housing 100 from the outlet 102. The water flow direction can be seen in the figure.

[0101] Optional, see reference Figure 19 The cavity inside the housing 100 is connected to the sludge collection port 103. The second filter cover 212 of the filter device 210 may have a through-hole that communicates with the sludge collection port 103, so that the water flowing from the sludge collection port 103 can directly enter the filter channel 101.

[0102] Specifically, taking a water tank as an example, when the cleaning device 10 is working at the bottom of the tank, the water carrying dirt enters the filter channel 101 from the inlet 111 and has at least two flow paths.

[0103] In one path, water flows from the collection port 103 into the filter channel 101 and passes through the second filter cover 212. During this process, impurities are trapped in the filter channel 101 by the second filter cover 212, while the filtered water flows into the gap between the second filter cover 212 and the inner wall of the receiving cavity. Then, under the suction action of the suction device 220, it enters the inlet of the suction device 220 and is finally discharged from the housing 100 through the outlet 102.

[0104] In another path, after the water flows into the filter channel 101 from the sludge collection port 103, it passes through the first filter cover 211. During this process, impurities are trapped in the filter channel 101 by the first filter cover 211, while the filtered water can pass through the first filter cover 211 under the suction action of the suction device 220. During this process, most of the water flows to the water inlet of the suction device 220, and a small part of the water can directly enter the interior of the first filter cover 211 and finally be discharged from the housing 100 through the water outlet 102.

[0105] The design of the sewage collection port 103 and the sewage inlet 111 enhances the adaptability of the cleaning equipment 10 to various tasks such as underwater pool bottom cleaning and water surface cleaning.

[0106] Optionally, the scraper 500 may be designed to be discontinuous along its length. This discontinuous design allows the scraper 500 to include a plurality of scraper teeth or blades spaced apart along its extension direction.

[0107] This design can effectively reduce the overall water resistance encountered by the scraper 500 during its movement, while ensuring that it plays a major role in blocking and guiding larger volumes of dirt, thus making the cleaning equipment 10 operate more smoothly.

[0108] Furthermore, when the cleaning equipment 10 traverses uneven surfaces, the continuous scraper blades 500 are prone to significant internal stress due to overall bending deformation, posing a risk of stress concentration and potentially leading to fatigue fracture with prolonged use. This intermittent design allows each scraper tooth to operate independently. When encountering uneven surfaces, each tooth can independently undergo minute elastic deformation to adapt to the terrain, thereby dispersing concentrated bending stress and preventing structural damage caused by overall torsion.

[0109] Optionally, a cover 1115 may be provided at the inlet 111. The cover 1115 can be installed at the inlet 111 by means of hinges, slides, or magnetic adsorption. When the bottom of the pool needs to be cleaned, the suction device 220 is activated and generates suction. The cover 1115 can be automatically opened by the suction of the water flow or by a control device (such as a solenoid valve), allowing dirt and water to enter the filter channel 101 normally. When the suction device 220 stops working, the cover 1115 will close the inlet 111.

[0110] Optionally, a side sealing end cover may also be provided at the sewage collection port 103. The side sealing end cover can be installed at the sewage collection port 103 by means of hinges, slides, or magnetic adsorption. In one example, the side sealing end cover can be opened or closed by a stepper motor. Specifically, one end of the side sealing end cover is fixedly connected to the output shaft of the stepper motor, and the stepper motor controls the opening or closing of the side sealing end cover by controlling the rotation of the output shaft.

[0111] When water surface cleaning is required, the suction device 220 is activated and generates suction. The side sealing end cap can rotate and open the dirt collection port 103 under the drive of the output shaft of the stepper motor, allowing dirt and water to enter the filter channel 101 normally. When the suction device 220 stops working, the stepper motor drives the side sealing end cap to close the dirt collection port 103.

[0112] As can be seen, the cover 1115 and the side end cover both act as active one-way valves, ensuring that the fluid can only flow from the inlet 111 or the collection port 103 from the outside to the inside of the cleaning equipment 10, and preventing the internal dirt and water from flowing out in reverse, thus avoiding the problem of dirt backflow that may occur due to improper closure in traditional designs.

[0113] Optionally, when cleaning the bottom of the pool, only the cover 1115 can be controlled to open the sludge inlet 111, at which time the side sealing end cover blocks the sludge collection outlet 103; when cleaning the water surface, only the side sealing end cover can be controlled to open the sludge collection outlet 103, at which time the cover 1115 blocks the sludge inlet 111.

[0114] In some embodiments, combined with Figure 2 and Figure 7The scraper 500, the bottom shell 110, and the surface to be cleaned together define a suction space 600 that opens toward the first cleaning component 400. When the cleaning device 10 moves along the surface to be cleaned, the scraper 500 gathers the dirt raised by the first cleaning component 400 into the suction space 600.

[0115] The scraper 500 can be made of an elastic material, such as rubber or plastic, and the scraper 500 can be located on the side of the inlet 111 facing away from the first cleaning member 400 and adjacent to the inlet 111.

[0116] The scraper 500 forms a closed or semi-closed suction space 600 with the bottom shell 110 and the surface to be cleaned, limiting the range of the suction area and guiding the direction of fluid flow. The opening of the suction space 600 faces the first cleaning component 400, and a gradually narrowing channel can be formed by adjusting the shape and position of the scraper 500. The suction space 600 can be used to collect the stirred-up dirt, reduce the spread of dirt, and improve suction efficiency.

[0117] Specifically, when the cleaning device 10 moves, the first cleaning component 400 lifts up the dirt on the surface to be cleaned, and the scraper 500 reduces the amount of fluid entering the suction space 600, creating a negative pressure area within the suction space 600. The lifted dirt enters the suction space 600 with the fluid and is guided by the scraper 500 to concentrate at the inlet 111.

[0118] In this way, the scraper 500 prevents the splashed dirt from spreading backward and sideways, thus achieving effective collection of dirt.

[0119] In some embodiments, combined with Figure 2 and Figure 7 The suction space 600 includes a first end 601 facing the first cleaning member 400 along a first direction and a second end 602 facing the scraper 500, in the direction from the first end 601 to the second end 602 (i.e. Figure 2 (In the negative x-axis direction), the size of the suction space 600 gradually decreases, and the inlet 111 is set close to the second end 602.

[0120] This design gives the suction space 600 a cross-sectional shape that is a wide opening facing the first cleaning element 400, gradually narrowing to the inlet 111 near the end of the scraper 500. When the water carrying dirt enters from the wide first end 601 and flows towards the gradually narrowing second end 602, the reduction in the cross-sectional area of ​​the flow channel leads to an increase in water flow velocity. This increase in water flow velocity creates a stronger local low-pressure zone near the inlet 111 (i.e., the second end 602), thereby enhancing the suction force at the inlet 111 and improving the efficiency of capturing and sucking up dirt.

[0121] In addition, the constricted structure of the space guides and compresses the water flow, forcing the waste to converge towards the center of the inlet 111, effectively preventing the accumulation or escape of waste at the edge of the space, and ensuring the concentration and efficiency of the suction.

[0122] In some embodiments, combined with Figure 2 , Figure 7 and Figure 17 The scraper 500 includes a body section 510 and two guide sections 520. The body section 510 is located on the side of the inlet 111 facing away from the first cleaning component 400 along the first direction. The two guide sections 520 are respectively located at both ends of the body section 510 along the second direction. One end of the guide section 520 is connected to the body section 510, and the other end extends obliquely toward the first cleaning component 400.

[0123] The design makes the scraper 500 present an open, surrounding shape towards the first cleaning component 400. The main body section 510 can serve as the main blocking surface, effectively preventing dirt from spreading backward. The two guide sections 520 extend obliquely forward from both ends of the main body section 510 (i.e., towards the first cleaning component 400), forming a three-sided surrounding, front-opening suction space 600 together with the main body section 510.

[0124] The two guide sections 520 serve to guide and gather water and dirt, constraining the water flow and preventing it from escaping from the left and right sides of the inlet 111. They also guide dirt from the front side to the center of the inlet 111, so that the water and dirt stirred up by the first cleaning component 400 can be effectively gathered and guided to the inlet 111, further reducing the loss of suction and improving the cleaning coverage width and dirt capture efficiency in the edge area.

[0125] In some embodiments, combined with Figure 2 , Figure 7 and Figure 17 In the first direction and from the second end 602 toward the first end 601, the end of the guide section 520 away from the body section 510 extends beyond the side edge of the inlet 111 toward the first cleaning member 400, or is flush with the side edge of the inlet 111 toward the first cleaning member 400.

[0126] This design ensures that the guide section 520 has sufficient longitudinal extension length, allowing its flow-guiding boundary to completely cover the entire front opening area of ​​the inlet 111. Thus, when the front end of the guide section 520 extends beyond or is flush with the leading edge of the inlet 111, it provides a direct flow path for the incoming water and debris to reach the inlet 111. Lateral flow is always constrained by the guide section 520, effectively preventing debris from escaping from the left and right sides during the final stage of entering the inlet 111, ensuring the integrity and reliability of the debris collection effect.

[0127] Optional, combined Figure 17 The included angle A between the body segment 510 and the guide segment 520 is 90°-135°. For example, the included angle A between the body segment 510 and the guide segment 520 can be 90°, 95°, 100°, 110°, 120°, 125°, 130°, 135°, etc.

[0128] When the angle between the main body section 510 and the guide section 520 is within this range, the guide section 520 can effectively guide the water and debris flowing in from the side and front, converging them towards the center area of ​​the inlet 111. It also avoids the guide section 520 becoming too straight and losing its converging effect due to an excessively large angle, or the guide section 520 becoming too small and failing to allow smooth flow of debris at the angle between it and the main body section 510. This angle design ensures that the scraper blade 500 achieves optimal debris collection efficiency while maintaining a compact structure.

[0129] Optional, see reference Figure 4 The surface to be cleaned can be line G as shown in the figure. The distance a between the end of the scraper 500 away from the housing 100 and the surface G to be cleaned is 0.5mm-2mm. For example, the distance a can be 0.5mm, 1mm, 1.5mm, 2mm, etc.

[0130] This spacing effectively prevents the dirt that has been lifted from escaping from the bottom of the scraper 500, ensuring that most of the dirt is confined within the suction space 600 and captured by the suction device 220. It also provides the necessary tolerance space for the cleaning device 10 to move smoothly on uneven surfaces to be cleaned, avoiding problems such as scraping, jamming, or additional wear caused by too small a spacing.

[0131] In some embodiments, not shown in the figures, the ratio of the height of the scraper 500 extending out of the base housing 110 to the distance between the base housing 110 and the surface to be cleaned is greater than 1 / 2. For example, this ratio could be 2 / 3, 3 / 4, 4 / 5, etc.

[0132] When the ratio is within this range, the scraper 500 can extend sufficiently close to the surface to be cleaned, thereby effectively achieving its function of scraping and blocking dirt. In addition, this ratio avoids the problem of excessive resistance or accelerated wear that may result from the scraper 500 extending too far.

[0133] Through this ratio optimization design, the scraper 500 can play a better role in guiding and collecting dirt in the flow channel formed by the bottom shell 110 and the surface to be cleaned, ensuring cleaning efficiency and improving the stability of the cleaning equipment 10 operation and the durability of the scraper 500.

[0134] In some embodiments, combined with Figure 2 and Figure 3The first cleaning component 400 is a roller brush, and the distance d between the edge of the inlet 111 facing the first cleaning component 400 and the central axis of the first cleaning component 400 in the first direction is 80mm-300mm. For example, the distance d can be 80mm, 80.5mm, 90mm, 100mm, 140mm, 180mm, 200mm, 250mm, 270mm, 280mm, 280.5mm, 290mm, 290.5mm, 300mm, etc.

[0135] Optionally, the roller brush can be implemented using a rotating shaft 720 structure with bristles or scrapers on the surface, which rolls up the dirt and throws it toward the dirt inlet 111 by rotating the roller brush.

[0136] As the roller brush rotates and lifts up the sludge from the bottom of the pool, the sludge enters the suction space 600 and is lifted towards the inlet 111 by the water flow. If the spacing is too small, the sludge may not have enough time to be lifted; if the spacing is too large, it may cause the water flow speed to decrease and the sludge to settle again, affecting the suction efficiency.

[0137] The spacing d, ranging from 80 mm to 300 mm, provides the necessary space for the full uplift and diffusion of contaminants, allowing them to mix thoroughly with the water flow to form a uniform suspension. Furthermore, this spacing ensures that the suspended contaminants retain sufficient kinetic energy as they begin to converge towards the inlet 111 under suction, enabling them to be efficiently drawn into the inlet 111.

[0138] In some embodiments, combined with Figure 2 and Figure 7 The sewage inlet 111 includes two first edges 1111 opposite each other along a first direction and two second edges 1112 opposite each other along a second direction. The second edges 1112 are parallel to the guide section 520 on the side where they are located.

[0139] This design ensures that the side profile of the inlet 111 is consistent with the extension direction of the guide section 520, forming a smooth flow channel. When the water flow and sewage flow gathered by the guide section 520 flow towards the inlet 111, the parallel side edges can reduce the impact and turbulence loss between the water flow and the inlet edge, allowing the sewage to smoothly enter the filter channel 101.

[0140] The parallel design of the second edge 1112 and the guide section 520 on its side optimizes the flow field distribution near the sewage inlet 111, avoiding energy loss and sewage retention caused by abrupt changes in flow direction, and further improving the suction efficiency.

[0141] In some embodiments, combined with Figure 2 and Figure 7The inner wall of the inlet 111 includes a first sidewall 1113 where the first edge 1111 is located and a second sidewall 1114 where the second edge 1112 is located. At least one of the first sidewall 1113 and the second sidewall 1114 extends obliquely to the bottom wall of the adjacent bottom shell 110.

[0142] The inclined extension design of the first sidewall 1113 and / or the second sidewall 1114 makes the inlet 111 form a certain opening angle or flared structure at the end near the surface to be cleaned. This design can more smoothly guide the sewage and water flow gathered by the scraper 500 into the inlet 111, effectively reducing the collision and rebound of sewage at the inlet edge and reducing the risk of blockage.

[0143] In addition, the tilted design helps to improve the flow field distribution inside the inlet 111, reduce the generation of eddies, and enable the suction force of the suction device 220 to act more concentratedly on the surface to be cleaned, thereby improving the suction efficiency of dirt.

[0144] In some embodiments, combined with Figure 2 , Figure 7 and Figure 20 The bottom shell 110 also includes a third region 118, which is located on the side of the first region 112 facing away from the second region 113 along the first direction. The distance between the third region 118 and the surface to be cleaned is greater than the distance between the first region 112 and the surface to be cleaned. The first cleaning component 400 is disposed in the third region 118.

[0145] The third area 118 at the front end of the cleaning device 10 is set to have a large distance from the surface to be cleaned, which can provide sufficient operating space for the first cleaning component 400 (such as a roller brush). This operating space allows the water flow and dirt raised by the first cleaning component 400 to have enough area for initial mixing and suspension, avoiding problems such as dirt being crushed by the first cleaning component 400 due to the space being too small.

[0146] In this way, the dirt is fully stirred up and mixed, and then efficiently captured by the high-speed water flow in the first area 112, which is close to the surface to be cleaned, thus ensuring cleaning efficiency.

[0147] In some embodiments, combined with Figure 2 and Figure 7 The bottom shell 110 also includes a transition region 114 connecting the first region 112 and the second region 113, the transition region 114 extending obliquely relative to the first region 112 and the second region 113.

[0148] The inclined extension design of the transition area 114 makes the change between the first area 112 and the second area 113 a smooth, gradually rising slope. When the cleaning device 10 moves, the water flow and some of the dirt that is lifted will flow from the second area 113, which is close to the surface to be cleaned, to the first area 112. The smooth inclined transition can greatly reduce the turbulence and energy loss of the water flow, guide the water flow smoothly, and avoid the eddies that may be generated at the height change.

[0149] In addition, when the cleaning equipment 10 crosses small obstacles (such as tile joints or pebbles) that are higher than the surface to be cleaned, the inclined transition area 114 acts as a "lifting guide slope", allowing the cleaning equipment 10 to pass through the obstacles smoothly, reducing the risk of getting stuck or stranded, and ensuring the continuity of the cleaning operation.

[0150] Optional, see reference Figure 9 The surface to be cleaned can be line G as shown in the figure. The distance b between the first region 112 and the surface G to be cleaned is 10mm-15mm. For example, this distance can be 10mm, 11mm, 11.5mm, 13mm, 14mm, 14.5mm, 15mm, etc. Optionally, the distance c between the second region 113 and the surface G to be cleaned is 15mm-20mm. For example, this distance can be 15mm, 15.5mm, 16mm, 17mm, 19mm, 19.5mm, 20mm, etc.

[0151] This size range design ensures that the first zone 112 is close enough to the surface to be cleaned, thereby forming a narrow flow channel with high flow velocity and concentrated suction below the inlet 111, improving the efficiency of dirt collection. In addition, the slightly larger spacing of the second zone 113 provides the necessary floating space for the cleaning device 10 to move, and also increases the space for dirt collection, ensuring the effectiveness of dirt collection.

[0152] In some embodiments, combined with Figure 2 and Figure 7 The bottom shell 110 is also provided with a plurality of water passage holes 115, some of which are located in the first region 112 and some in the second region 113.

[0153] When the cleaning device 10 is placed in the water, the water flow can quickly enter the internal space of the bottom shell 110 through the water inlet 115, expelling air and helping the cleaning device 10 to sink quickly to the working position. When cleaning is completed and the cleaning device 10 is lifted out of the water, the water stored in the internal cavity of the bottom shell 110 can be quickly discharged through these water inlet 115, effectively reducing the total weight of the cleaning device 10 when it is discharged, and also preventing a large amount of water from being carried out of the pool, making it convenient for users to collect and store.

[0154] In addition, the water holes 115 located in the first area 112 and the second area 113 help to balance the water pressure above and below the bottom shell 110, so that the cleaning device 10 can maintain a stable ground posture, avoid shaking or tilting caused by uneven water pressure, and ensure smooth walking and uniform cleaning.

[0155] In some embodiments, combined with Figure 8 , Figure 9 , Figure 11 and Figure 20 At least a portion of the structure of the third region 118 is recessed to form a working space 116. The first cleaning component 400 is rotatably disposed in the working space 116. The bottom of the inner wall of the working space 116 is arc-shapedly transitioned to the portion of the bottom shell 110 other than the working space 116.

[0156] This design allows the roller brush to be partially embedded in the bottom shell 110 structure, reducing the overall height of the cleaning device 10 and making the cleaning operation position of the roller brush more reasonable.

[0157] In addition, the bottom of the inner wall of the working space 116 and the part of the bottom shell 110 other than the working space 116 are designed with a rounded transition, which eliminates the sharp corners that may be formed by the right angle transition in the traditional design. This allows the water flow and the dirt raised by the roller brush to flow smoothly along the smooth arc inner wall to the dirt inlet 111 when the cleaning equipment 10 moves, reducing flow resistance and turbulence, and preventing dirt from accumulating and getting stuck in the corners.

[0158] In addition, the smooth curved surface is easier to clean and less prone to stains, ensuring the long-term working efficiency of the cleaning equipment 10. It also reduces stress concentration and enhances the mechanical strength and durability of the bottom shell 110 in that area.

[0159] In some embodiments, combined with Figure 2 , Figure 3 and Figure 10 The first cleaning component 400 includes a cleaning body 410 and cleaning ribs 420 disposed on the surface of the cleaning body 410. There are multiple cleaning ribs 420, and the multiple cleaning ribs 420 are divided into several cleaning groups 421 that are spaced apart along the axial direction of the cleaning body 410. Each cleaning group 421 includes several cleaning ribs 4211 that are spaced apart along the circumferential direction of the cleaning body 410.

[0160] Optionally, the cleaning ribs 420 can be strip-shaped structures protruding from the surface of the cleaning body 410, and can be made of flexible rubber or silicone material, which can lift up the stains attached to the surface to be cleaned during rotation. The cleaning group 421 can be a collection of multiple cleaning ribs 4211 arranged at intervals along the axial direction of the cleaning body 410. Specifically, it can be achieved by distributing the cleaning ribs 4211 at adjacent axial positions in a circumferentially staggered manner, thereby forming multiple independent cleaning areas.

[0161] This grouped layout creates a matrix-like distribution of cleaning ribs 420 on the surface of the cleaning body 410. When the cleaning body 410 rotates, the cleaning ribs 4211 in different cleaning groups 421 contact the surface to be cleaned in sequence, breaking down the continuous friction cleaning action into high-frequency and intermittent tapping and scraping. This dynamic action helps to break up and lift firmly attached stains more effectively.

[0162] In addition, the spacing design between the cleaning ribs 4211 and between the cleaning groups 421 provides a flow channel for water and the raised dirt, allowing it to flow smoothly to the inlet 111, further improving cleaning efficiency.

[0163] Optional, see reference Figure 10 A water passage hole 411 can be provided on the cleaning body 410. When the cleaning device 10 is placed in water, water can quickly enter the interior of the cleaning body 410 through the water passage hole 411, expelling air and preventing local air trapping. When the cleaning task is completed and the cleaning device 10 is taken out of the water, the water accumulated inside the cleaning body 410 and between the cleaning ribs 420 can quickly flow out through the water passage hole 411, so that the water inside and outside the cleaning body 410 can be quickly discharged after leaving the water surface, avoiding the cleaning body 410 from becoming too heavy due to internal water accumulation.

[0164] Optionally, the gap between adjacent cleaning groups 421 may extend in the cleaning body 410 in a spiral shape with a preset angle relative to the axis of the cleaning body 410, or in an S-shape with a spiral shape with a preset angle relative to the axis of the cleaning body 410.

[0165] When the gap extends through the surface of the cleaning body 410 in a spiral or inclined manner, it forms a continuous guide channel at a preset angle to the axis of the cleaning body 410.

[0166] Thus, when the first cleaning component 400 rotates, the spiral gap guides the water flow and the raised dirt, creating a component velocity along the axial direction of the cleaning body 410. This axial force pushes the dirt and actively gathers it towards the rear inlet 111, improving the efficiency of dirt transport and capture.

[0167] In some embodiments, combined with Figure 2 , Figure 3 and Figure 10 The arrangement path of multiple cleaning ribs 4211 belonging to the same cleaning group 421 is a spiral extending around the axis of the cleaning body 410.

[0168] When the cleaning body 410 rotates, the multiple cleaning ribs 4211 distributed along the spiral path can generate a continuous component force along the axis of the cleaning device 10. This component force can push the raised dirt from both sides of the working space 116 towards the central area, thereby effectively coordinating with the position of the dirt inlet 111 to better gather the dirt onto the suction path.

[0169] In addition, the continuous scraping action formed by the spiral path can cover a more comprehensive area, avoiding the cleaning dead spots that may exist in straight ribs, and further improving the uniformity of cleaning.

[0170] In some embodiments, combined with Figure 2 , Figure 8 , Figure 11 and Figure 12 The first cleaning component 400 includes two cleaning units 430 distributed along a second direction. The cleaning device 10 also includes a mounting bracket 710 and a rotating shaft 720. The mounting bracket 710 is disposed between the two cleaning units 430 and connected to the bottom shell 110, and has a shaft hole 711. The rotating shaft 720 passes through the shaft hole 711, and its two ends are respectively connected to the shell 100. The two cleaning units 430 are both sleeved on the rotating shaft 720 and are located on both sides of the mounting bracket 710.

[0171] Mounting bracket 710 can be a support structure for connecting two cleaning units 430 and fixing them to the base shell 110. Optionally, mounting bracket 710 can be made of metal or high-strength plastic, which can play a role in distributing load.

[0172] Optionally, a bearing may also be installed at the shaft hole 711. For example, the bearing may be a ball bearing, a rubber bearing, etc. The rolling friction of the bearing 730 reduces the rotational resistance of the shaft 720, allowing the first cleaning component 400 to rotate more smoothly, reducing wear, and extending the service life of the first cleaning component 400 and the mounting bracket 710.

[0173] The rotating shaft 720 can pass laterally through the shaft hole 711 of the mounting bracket 710, and its two ends are connected to the side wall of the housing 100 through bearings or shaft seats to form a rotatable support structure. Two cleaning units 430 are respectively sleeved on the rotating shaft 720 and located at the left and right ends of the mounting bracket 710. When the cleaning device 10 moves, the two cleaning units 430 contact different areas of the surface to be cleaned, and the mounting bracket 710 can maintain the distance between them to prevent interference.

[0174] The mounting bracket 710 provides a stable central support point for the rotating shaft 720, ensuring support strength and guaranteeing the stability and concentricity of the cleaning unit 430 during rotation. Furthermore, this split design facilitates maintenance and replacement; if one side of the cleaning unit 430 is damaged, it can be replaced individually, reducing maintenance costs.

[0175] Optionally, the mounting bracket 710 is positioned in the middle between the two cleaning units 430 and can be fixedly connected to the base shell 110 by bolts or clips.

[0176] For example, in combination Figure 11 The bottom shell 110 may have a slot, and the mounting bracket 710 has a hook 712 at a position corresponding to the slot. During assembly, the hook 712 on the mounting bracket 710 can be inserted into the slot of the bottom shell 110 to achieve pre-positioning and initial fixation of the mounting bracket 710 and the bottom shell 110.

[0177] Additionally, the base shell 110 may have a first screw hole, and a corresponding mounting block 713 may be provided on the mounting bracket 710, with a connecting hole provided on the mounting block 713. By passing a fastener (such as a screw) through the connecting hole and screwing it into the first screw hole, a secure connection between the mounting bracket 710 and the base shell 110 can be achieved. This combination of snap-fit ​​and bolt connection scheme ensures structural strength and stability, and also facilitates the disassembly and maintenance of the mounting bracket 710.

[0178] Optional, combined Figure 11 The cross-section of the mounting bracket 710 can be fan-shaped, giving the mounting bracket 710 an arc surface. The arc surface can serve as a mounting surface to fit against the bottom shell 110. The hook 712 and the mounting block 713 can be respectively located at both ends of the arc surface. Optionally, the arc surface can fit against the inner wall of the working space 116.

[0179] The curved surface, as the mounting surface, ensures a larger contact area between the mounting bracket 710 and the bottom shell 110, improving the stability of the connection and the overall structural strength. The hooks 712 and the mounting blocks 713 are placed at both ends of the curved surface, which is equivalent to fixing the mounting bracket 710 at two main support points. This diagonal arrangement can effectively prevent the mounting bracket 710 from warping or twisting under stress, ensuring its reliability in supporting the two cleaning units 430.

[0180] In addition, the fan-shaped structure is also conducive to the rational layout within a limited space, leaving sufficient space for the cleaning unit 430 and the transmission components to move.

[0181] In some embodiments, combined with Figure 13 and Figure 14 The first cleaning element 400 includes two cleaning units 430 distributed along a second direction; each cleaning unit 430 is in the form of a cone or a frustum, and the generatrix of the cleaning unit 430 is in contact with the surface to be cleaned; the two cleaning units 430 are configured to contact each other on the surface to be cleaned.

[0182] When the cleaning unit 430 is a frustum, it has a first end face and a second end face at both ends of the cleaning unit 430, and the diameter of the first end face is smaller than the diameter of the second end face. Optionally, the two cleaning units 430 can be configured as cones with their tops facing away from each other or frustums with their first end faces facing away from each other.

[0183] Taking two cleaning units 430 configured as a frustum with their first end faces facing away from each other as an example. The two cleaning units 430 are in contact on the surface to be cleaned, that is, the two generatrices (side diagonal lines) are in contact with the surface to be cleaned, and the two second end faces are in contact with each other below the middle mounting bracket 710.

[0184] Thus, when the cleaning unit 430 rotates, its outer edge has the highest linear velocity, and the part with the strongest cleaning force covers the area below the mounting bracket 710. The two cleaning units 430 are almost in contact with the surface to be cleaned, with almost no gaps between them, making the area below the mounting bracket 710 virtually free of cleaning dead corners. The rotating frustum surface can sweep away dirt from the bottom of the mounting bracket 710, achieving cleaning without dead corners. The two frustums are arranged opposite each other, jointly guiding the dirt to the rear dirt inlet 111, improving cleaning efficiency.

[0185] In addition, compared to cylindrical roller brushes, this contact method can more gently adapt to the slight undulations of the ground and effectively remove stains adhering to the surface to be cleaned by combining scraping and rolling.

[0186] Optional, combined Figure 13 and Figure 14 The cleaning unit 430 is in the shape of a cone or a frustum. The cleaning ribs 4211 on the cleaning unit 430 are at a preset angle (i.e., inclined) relative to the axis of the cleaning unit 430, so as to form a guide structure that guides and gathers the dirt on the surface to be cleaned toward the central area of ​​the inlet 111.

[0187] When the cleaning body 410 rotates, the inclined cleaning ribs 4211 act like a screw conveyor, agitating and lifting the dirt while applying a continuous axial force. This pushes the dirt on both sides of the cleaning area towards the center and ultimately guides it to the dirt inlet 111 at the rear, improving the efficiency of dirt collection.

[0188] Optionally, each cleaning unit 430 is frustum-shaped, and the second end face of the cleaning unit 430 is ball-jointed to the mounting bracket 710.

[0189] The ball joint design can transmit torque and also allows the cleaning unit 430 to adaptively deflect when subjected to lateral forces. When the cleaning device 10 moves on an uneven surface to be cleaned, the two cleaning units 430 can float and deflect slightly independently under the constraint of the ball joint, ensuring that the busbar is always in contact with the surface to be cleaned.

[0190] Optionally, the mounting bracket 710 may be equipped with a drive unit, which is connected to the second end face of the cleaning unit 430 via a ball joint. For example, the drive unit may be a miniature motor.

[0191] The drive unit can directly drive the cleaning unit 430 to rotate via a ball joint mechanism. This direct drive, combined with the movable connection, allows the cleaning unit 430 to dynamically scrape the bottom edge of the mounting bracket 710 when rotating. Combined with the advantages of the truncated cone shape, it can effectively remove the cleaning dead corners under the mounting bracket 710.

[0192] In some embodiments, combined with Figure 2 and Figure 7 The bottom shell 110 is also provided with a mounting hole 117, which is located between the sewage inlet 111 and the first cleaning component 400; the cleaning device 10 also includes a downward-looking sensor 900, which is located in the mounting hole 117.

[0193] Optionally, the downward-facing sensor 900 can be implemented using optical sensors, cameras, ultrasonic sensors, infrared sensors, etc. It can directly obtain real-time information of the surface to be cleaned through the mounting hole 117, and can also monitor sudden changes in the ground in front (such as the edge of a swimming pool or the edge of a step) to achieve the anti-fall function.

[0194] When the cleaning equipment 10 is working at the edge of the pool, once the downward-facing sensor 900 detects that the ground in front of it suddenly disappears (such as when the detection distance increases sharply), it will immediately send this signal to the control system. The control system can then determine that the cleaning equipment 10 is on the verge of falling and immediately instruct the walking device 300 to stop moving forward or move in the opposite direction, effectively preventing the cleaning equipment 10 from falling off the steps or the edge of the pool and protecting the cleaning equipment 10 from impact damage.

[0195] Furthermore, by analyzing the acquired images or optical data, the downward-facing sensor 900 can also determine in real time the cleaning effect of the area to be cleaned that has already been cleaned by the roller brush, such as whether there are any stubborn stains remaining. This information is fed back to the control system of the cleaning device 10, which can then make decisions, such as instructing the cleaning device 10 to perform secondary cleaning in that area or adjusting the cleaning mode (such as increasing the roller brush speed). In this way, cleaning control driven by sensor feedback is achieved, improving the thoroughness and intelligence of the cleaning process.

[0196] In addition, the mounting hole 117 also protects the sensor lens from direct friction and scratches with the surface to be cleaned.

[0197] In some embodiments, combined with Figure 1 and Figure 2 , Figure 15a and Figure 15b ,in, Figure 15aand Figure 15b The diagram shows the structure of the cleaning device 10 in different embodiments. Figure 15a and Figure 15b All are bottom views of the cleaning equipment 10.

[0198] The cleaning device 10 also includes a second cleaning component 800, which is located at the bottom of the housing 100 at the end opposite to the first cleaning component 400 along the first direction.

[0199] The design includes cleaning tools at both the front and rear ends of the bottom of the cleaning device 10. The first cleaning component 400 at the front is mainly responsible for lifting up dirt in the core area, while the second cleaning component 800 at the rear undertakes auxiliary cleaning functions.

[0200] The main function of the second cleaning component 800 is to further scrape or sweep away any trace amounts of dirt that may remain during the movement of the cleaning equipment 10, and the two work together to improve the cleaning coverage.

[0201] In addition, in some examples, the cleaning device 10 can also move backward, that is, the second cleaning component 800 becomes the main cleaning component, still achieving the cleaning of dirt on the surface to be cleaned, and ensuring the cleaning effect by working in coordination with the first cleaning component 400.

[0202] In some embodiments, the second cleaning component 800 may also include at least one cleaning unit 430, and a mounting bracket 710 may be provided between adjacent cleaning units 430. The cleaning unit drive source of the second cleaning component 800 may be set independently or may share the same cleaning unit drive source with the first cleaning component 400.

[0203] In some embodiments, combined with Figures 1 to 3 , Figure 13 and Figure 14 ,as well as Figure 15a and Figure 15b The walking device 300 is constructed as a walking track 310. There are two walking devices 300, which are respectively located on both sides of the housing 100 along the second direction. The first cleaning component 400 and the second cleaning component 800 are located between the two walking devices 300, or the two walking devices 300 are located between the first cleaning component 400 and the second cleaning component 800.

[0204] In some embodiments, such as Figure 16a and Figure 16b As shown, Figure 16a and Figure 16b The diagram shows the structure of the cleaning device 10 in different embodiments. Figure 16a and Figure 16b All are bottom views of the cleaning equipment 10.

[0205] Either the first cleaning component 400 or the second cleaning component 800 may be disposed between the two traveling devices 300. For example, as shown... Figure 16a and Figure 16b The second cleaning component 800 is located between the two walking devices 300, while the first cleaning component 400 is located outside the end of the walking device 300 in the first direction.

[0206] The walking device 300 is constructed as a walking track 310. There are two walking devices 300, which are respectively located on both sides of the housing 100 along the second direction (y-axis direction). Along the positive x-axis direction, the first cleaning component 400 is located at the front end of the walking device 300, and the second cleaning component 800 is located between the two walking devices 300.

[0207] The first cleaning component 400 may include three cleaning units 430, which are arranged sequentially along the second direction. Each cleaning unit 430 may be provided with a mounting bracket 710. In this embodiment, the fixing method between the mounting bracket 710 and the housing 100 is not limited. It can be fixed by a fastener or by a snap-fit.

[0208] In this embodiment, the size of each cleaning unit 430 can be the same or different. The following example uses three cleaning units 430.

[0209] Optionally, the cleaning unit 430 located at the edge may be smaller than any of the other two cleaning units 430. Optionally, the cleaning unit 430 located in the middle may also be smaller (or larger) than any of the other two cleaning units 430.

[0210] This dimension can be either the axial dimension or the radial dimension of the cleaning unit 430.

[0211] In some embodiments, such as Figure 16a As shown, along the positive y-axis, the axial length of the leftmost cleaning unit 430 is less than the axial length of either of the two cleaning units 430 to its right; in some embodiments, such as Figure 16b As shown, along the positive y-axis, the axial length of the rightmost cleaning unit 430 is smaller than the axial length of either of the two cleaning units 430 to its left. This design of a smaller first cleaning element 400 at the edge helps improve the cleaning device's mobility and cleaning effectiveness in edge areas such as pool walls or corners.

[0212] In some embodiments, the driving methods of different cleaning units 430 can be the same or different, and can be achieved by gear driving or by belt driving, etc.

[0213] Optionally, in some examples, refer to Figure 16a and Figure 16bThe larger cleaning unit 430 can use an independent drive source (such as a drive motor) to achieve torque output, while the smaller cleaning unit 430 located at the edge can be driven independently, so that its speed and direction can be adjusted independently to achieve more precise corner cleaning. It can also be driven coaxially with the adjacent larger cleaning unit 430, with all three sharing the same drive shaft.

[0214] Correspondingly, the structure of the second cleaning component 800 can adopt the same modular design as the first cleaning component 400. Specifically, the second cleaning component 800 can also include multiple cleaning units 430, and the sizes of the multiple cleaning units 430 can be configured differently. For example, the cleaning unit 430 located at any edge in the second direction can be smaller, and the connection and positioning between adjacent cleaning units 430 can be achieved through the mounting bracket 710. The driving method of the cleaning units 430 of the second cleaning component 800 can also be flexible, and can be driven independently or multiple cleaning units 430 can share the drive.

[0215] The use of a tracked walking device 300 provides sufficient ground contact area and obstacle-crossing capability, ensuring that the cleaning equipment 10 moves stably on wet or uneven pool bottoms.

[0216] When the first cleaning component 400 and the second cleaning component 800 are located between the two walking devices 300, the tracks form stable support on both sides, causing the cleaning components to be concentrated in the central area of ​​the bottom of the cleaning device 10; when the two walking devices 300 are located between the first cleaning component 400 and the second cleaning component 800, the distribution of the first cleaning component 400 and the second cleaning component 800 is further outward, which can expand the coverage width of a single cleaning.

[0217] In addition, this application embodiment also provides a cleaning system, which includes the cleaning device 10 and a base station, wherein the base station is at least configured to clean the filter device 210 of the cleaning device 10 or to charge the cleaning device.

[0218] Once the cleaning device 10 has completed its water tank cleaning task or detected a clogged filter, it can automatically return or be placed at the base station by the user. The base station may have a built-in cleaning mechanism, such as reverse water flow rinsing, brushing, or vibration components, which can actively remove dirt and impurities accumulated on the filter device 210 of the cleaning device 10. In addition, the base station may also integrate a charging function to replenish the power of the cleaning device 10.

[0219] By designing the aforementioned cleaning device 10, the cleaning system enhances the adsorption capacity for airborne dirt and prevents the adsorbed dirt from escaping due to water flow disturbance, thus ensuring cleaning efficiency.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and alterations may be made without departing from its scope.
