Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a cleaning equipment and a cleaning system. BACKGROUND

[0002] With the improvement of people's living standards, swimming pools as important facilities for leisure and fitness are increasingly popular in families, communities and public places. In order to keep the water quality of swimming pools clean and sanitary and reduce the cost of manual maintenance, swimming pool cleaning robots have emerged and are widely used. Such robots usually have autonomous or semi-autonomous operation capability and can move radially to clean the water surface, pool bottom and pool wall of the pool, effectively removing algae, silt, leaves, insects and other suspended or deposited dirt.

[0003] During the cleaning process, the swimming pool cleaning robot generates negative pressure through the built-in suction device, causing the surrounding water and the entrained dirt to flow into the filter chamber inside the robot. A filter screen is provided in the filter chamber to trap solid impurities in the water, separating the dirt from the water. The filtered cleaning water is then discharged back to the swimming pool, thereby improving the water quality of the overall water circulation system while completing the cleaning.

[0004] However, during long-term continuous operation, the surface of the filter screen in the filter chamber is prone to clogging as the trapped dirt accumulates. This clogging phenomenon can cause a significant increase in the resistance of water flow through the filter screen, thereby reducing the suction efficiency and cleaning capacity of the robot. At the same time, to maintain normal flow, the suction device (such as a water pump) needs to do extra work, which not only increases energy consumption but also can shorten the service life of the device due to overloading. In addition, when the clogging is severe, it can trigger the robot protection mechanism to cause shutdown, affecting the continuity and efficiency of the cleaning operation. SUMMARY

[0005] The embodiments of the present application provide a cleaning equipment and a cleaning system, which clean the surface of the filter element through the filter screen cleaning device, avoid the clogging of the filter screen after long-term operation of the cleaning equipment, and are beneficial to improve the reliability of the cleaning equipment during long-term operation.

Many changes and modifications can be made to the application described, in the light of the detailed disclosure, without departing from the spirit of the application. DETAILED DESCRIPTION

[0068] The exemplary embodiments will be described in detail in the following description with reference to the drawings. Unless otherwise noted, the same or similar components in different drawings are denoted by the same or similar reference numerals. The following exemplary embodiments are described in the context of the implementation described. These embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0069] With the improvement of people's living standards, swimming pools as an important facility for leisure and fitness are increasingly popular in families, communities and public areas. In order to keep the water quality clean and sanitary, reduce the cost of manual maintenance, swimming pool cleaning robots have emerged and been widely used. Such robots usually have autonomous or semi-autonomous operation capability, and can move radially to clean the water surface, pool bottom and pool wall, effectively removing attached algae, silt, leaves, insects and other suspended or deposited dirt.

[0070] In the cleaning process, the pool cleaning robot generates negative pressure through the built-in suction device, so that the surrounding water and the entrained dirt flow into the filter chamber inside the robot. A filter screen is provided in the filter chamber to trap solid impurities in the water, separating the dirt from the water. The filtered cleaning water is then discharged back into the pool, thereby completing the cleaning while also improving the water quality of the overall water circulation system.

[0071] However, during long-term continuous operation, the filter screen surface of the filter chamber is prone to clogging as the trapped dirt accumulates. This clogging phenomenon can cause a significant increase in the resistance of water flow through the filter screen, thereby reducing the suction efficiency and cleaning capacity of the robot. At the same time, to maintain normal flow, the suction device (such as a water pump) needs to do extra work, not only increasing energy consumption, but also possibly shortening the service life of the device due to overload. In addition, severe clogging can trigger the robot protection mechanism to stop, affecting the continuity and efficiency of the cleaning operation.

[0072] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0073] For ease of description and understanding, unless otherwise specified, the first direction is the X direction shown in Figure 1 , the second direction is the Z direction shown in Figure 1 , and the third direction is the Y direction shown in Figure 1 , wherein X-Y defines a plane parallel to the horizontal plane, and Z is the height direction of the cleaning device.

[0074] Referring to Figures 1 to 32 , in a first aspect, the embodiments of the present application provide a cleaning device 100. The cleaning device can be a device such as a pool cleaning robot, a pool vacuum cleaner, an underwater cleaning device 100, etc. for pool cleaning, or a robot, etc. for ground cleaning. The specific presentation of the cleaning device is not limited by the present disclosure, as long as the principle of the present application can be implemented.

[0075] Referring to Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 17 and Figure 23 , the cleaning device 100 includes a housing 110, a dust collecting device 120, a suction device 130, a filter screen cleaning device 140, and an electric control box 150.

[0076] The shell 110 serves as an external support structure of the cleaning device 100, and is used to accommodate and protect the internal components. The shell 110 is internally provided with a first accommodating cavity 111. The shell 110 is provided with a dirty inlet 111a and a clean outlet 111b, which are respectively in communication with the first accommodating cavity 111. The first accommodating cavity 111 provides space for the dust collecting device 120 and fluid flow. The dirty inlet 111a is used to introduce the fluid to be cleaned, and the clean outlet 111b is used to discharge the filtered cleaning fluid.

[0077] For example, the shell 110 can include an outer shell 1101 and a middle frame 1102. The middle frame 1102 is arranged inside the outer shell 1101 and connected to the outer shell 1101, for example, by snap connection, bolt connection, etc. The first accommodating cavity 111 is located inside the middle frame 1102. The dirty inlet 111a can penetrate the outer shell 1101 and the middle frame 1102. The clean outlet 111b can be provided on the middle frame 1102. A cavity for accommodating components such as wires, pipelines, and floats can also be formed between the outer shell 1101 and the middle frame 1102.

[0078] The dust collecting device 120 is arranged in the first accommodating cavity 111. The dust collecting device 120 defines a filtering cavity 121, such that the filtering cavity 121 is located inside the first accommodating cavity 111. The filtering cavity 121 is in communication with the dirty inlet 111a and the clean outlet 111b, respectively. The dust collecting device 120 includes a filter 122 for intercepting particulate matter, hair, sand, and other impurities in the fluid, achieving physical filtration. The filter 122 is located on the upstream side of the clean outlet 111b along the fluid flow direction. In this way, the fluid enters the filtering cavity 121 inside the first accommodating cavity 111 from the dirty inlet 111a, is filtered by the filter 122, and then flows out of the first accommodating cavity 111 from the clean outlet 111b. This ensures that all incoming fluid must be filtered before being discharged, achieving separation of dirt and fluid, effectively preventing bypass of unfiltered fluid, and improving the reliability of the filtering effect.

[0079] Optionally, the filter 122 can be a filter screen.

[0080] The suction device 130 is arranged in the shell 110. The suction device 130 is used to drive the fluid to flow from the dirty inlet 111a to the clean outlet 111b via the filtering cavity 121. The suction device 130 generates a negative pressure difference to provide the power required for fluid flow, driving the fluid to flow from the dirty inlet 111a to the clean outlet 111b via the filtering cavity 121.

[0081] Further, to facilitate the filtered fluid to be discharged from the cleaning device 100, a fluid discharge port 1103 can be formed on the housing 110, which is in communication with the suction device 130. For example, when the cleaning device 100 is used as a pool cleaning robot, the fluid discharge port 1103 can be formed on the top of the housing 100; when the cleaning device 100 is used as a 100 sweeping robot, the fluid discharge port 1103 can be formed on the top or side of the housing 100. Of course, the present application is not limited thereto, and the position of the fluid discharge port 1103 can be reasonably arranged according to actual needs.

[0082] With reference to Figure 3 , Figure 4 , Figure 24 and Figure 25 It can be understood that the cleaning device 100 can have multiple working modes, such as water surface cleaning mode and underwater cleaning mode. In different cleaning modes, the position of the dirty inlet 111a can be different. For example, when the cleaning device 100 is in the water surface cleaning mode, the dirty inlet 111a is located on the upper part of the side wall of the housing 110, and the fluid enters the first containing cavity 111 from the dirty inlet 111a floating on the side wall of the cleaning device 100 working on the water surface, and is discharged from the housing 110 under the action of the suction device 130 after being filtered in the filtering cavity 121. When the cleaning device 100 is in the underwater cleaning mode, the dirty inlet 111a is located on the bottom wall of the housing 110, and the fluid enters the first containing cavity 111 from the dirty inlet 111a on the bottom wall of the cleaning device 100, and is discharged from the housing 110 under the action of the suction device 130 after being filtered in the filtering cavity 121. That is, the dirty inlet 111a on the housing 110 can be provided with multiple dirty inlets 111a, and the multiple dirty inlets 111a are in communication with the filtering cavity 121.

[0083] The dirty inlet 111a can be provided with a one-way valve, and the corresponding one-way valve is opened when the cleaning device 100 is operated in the corresponding mode.

[0084] The filter screen cleaning device 140 is adapted to move relative to at least part of the surface of the filter 122 to clean the filter 122. For example, the filter screen cleaning device 140 can include a scraper structure that is in contact with the surface of the filter 122 and moves along the surface of the filter 122 to scrape off dirt on the surface of the filter 122. Alternatively, the filter screen cleaning device 140 can also include a brushing mechanism (such as the cleaning brush 141 described below) that brushes the surface of the filter 122 during the relative movement of the filter screen cleaning device 140 along the surface of the filter 122. Alternatively, the filter screen cleaning device 140 can also include a vibration mechanism that is connected to the filter 122 to drive the filter 122 to vibrate, thereby shaking off dirt deposited on the filter 122, and preventing the filter 122 from being clogged by dirt deposited on the surface of the filter 122. Alternatively, the filter screen cleaning device 140 can also include a flushing mechanism having a flushing portion facing the filter 122, and the flushing mechanism flushes dirt on the surface of the filter 122 during the relative movement of the filter screen cleaning device 140 along the surface of the filter 122, thereby preventing the filter 122 from being clogged, prolonging the service life of the filter 122, and ensuring the cleaning effect of the filter 122.

[0085] It can be understood that the filter screen cleaning device 140 can also be a combination of a scraper structure, a brushing mechanism, a vibration mechanism, and a flushing mechanism, without causing conflicts and interference in the spatial layout and movement path of each component.

[0086] The electric control box 150 is arranged in the housing 110 and integrates a power management module and a control circuit. The electric control box 150 is used to supply power to the cleaning device 100 (the suction device 130, the filter screen cleaning device 140, and other electronic components).

[0087] When the cleaning device 100 of the present application is used for cleaning, the suction device 130 generates negative pressure to drive an external water flow containing dirt to enter the first containing cavity 111 through the dirt inlet 111a on the housing 110. The water flow carrying the dirt enters the filter cavity 121 and is filtered by the filter 122. In this process, solid impurities are trapped on the surface or inside of the filter 122, and the filtered water flow is discharged through the overflow port 111b downstream of the filter cavity 121 and reenters the environment.

[0088] As the operation time is prolonged, the dirt trapped on the surface of the filter 122 gradually accumulates, which can cause the filtering efficiency to decrease. At this time, the filter screen cleaning device 140 is started to move reciprocally or rotationally along the surface of the filter 122 to remove the dirt adhered to the filter 122 by physical scraping, brushing, or backflushing, thereby restoring the permeability and filtering efficiency of the filter 122 and ensuring the continuous and efficient operation of the device.

[0089] In a specific example, the suction device 130 can include an impeller cover 131 and a driving impeller 132 arranged inside the impeller cover 131, the driving impeller 132 being in transmission connection with a driving motor in the electric control box 150, the impeller cover 131 defining a flow discharge channel 133 and being arranged outside the driving impeller 132, the flow discharge channel 133 being in communication with the flow discharge port 1103 on the shell 110, and the driving impeller 132 generating negative pressure when rotating in the flow discharge channel 133 to provide driving force for fluid flow. That is, under the driving of the driving impeller 132, the fluid enters the filter cavity 121 from the dirt inlet 111a, is filtered through the filter element 122, and then flows out of the first containing cavity 111, and then enters the flow discharge channel 133 inside the impeller cover 131 and is discharged outside the cleaning device 100 through the flow discharge port.

[0090] In addition, according to the phase state of the fluid to be driven, the suction device 130 can be a water pump or an air pump, and the type of the suction device 130 can be reasonably set according to actual needs.

[0091] In some possible embodiments, under the control of the electric control box 150, the filter screen cleaning device 140 can periodically and automatically clean the surface of the filter element 122 during the operation of the cleaning device 100 or the shutdown gap of the cleaning device 100. On the one hand, this can help to reduce the flow decay caused by the clogging of the filter element 122 and ensure the long-term stable and efficient cleaning performance of the cleaning device 100. On the other hand, the automatic cleaning function reduces the dependence on manual disassembly and washing of the filter element 122, and the user does not need to frequently stop and clean, thereby improving the automation degree and use convenience of the cleaning device 100. At the same time, the automatic cleaning function also avoids the overload operation of the suction device 130 caused by the clogging of the filter screen, effectively protects the core components such as the water pump or the fan, reduces the equipment wear and failure rate, and prolongs the service life of the cleaning device 100 as a whole.

[0092] In addition, when the cleaning device 100 is a pool cleaning robot, the pool cleaning robot drives the water flow to be sprayed out of the flow discharge port 1103 through the suction device 130, and the water flow exerts a reverse force on the shell 110, so that the pool cleaning robot can walk closely to the side wall of the pool, thereby achieving the cleaning of the side wall of the pool. When the filter element 122 is clogged, the water flow sprayed out of the flow discharge port 1103 has insufficient pressure, so that the cleaning device 100 cannot clean closely to the side wall of the pool. However, the filter screen cleaning device 140 of the present application can remove the foreign matters clogging the mesh holes of the filter element 122, thereby ensuring that the water is sprayed out of the flow discharge port 1103 of the cleaning device 100, providing sufficient reaction force for the cleaning device 100, and ensuring that the cleaning device 100 can closely adhere to the side wall of the pool to prevent unstable adsorption and falling from the side wall of the pool.

[0093] In some possible embodiments, the dust collecting device 120 can be formed as a box structure that is adapted to the internal profile of the first accommodating cavity 111, and the dust collecting device 120 can be detachably arranged in the first accommodating cavity 111. For example, the first accommodating cavity 111 is provided with a dismounting opening at one end thereof along the third direction (Z direction), and a flap is arranged at the dismounting opening and used to flip to block the dismounting opening. The dust collecting device 120 can be embedded along the third direction or connected to the cavity wall of the first accommodating cavity 111 through buckling. A user can open the flap, dismount the dust collecting device 120, clean the garbage in the dust collecting device 120, or replace a new dust collecting device 120.

[0094] Reference Figure 9 、 Figure 10 、 Figure 17 and Figure 22 In some embodiments, the filter screen cleaning device 140 includes a cleaning brush 141 and a driving member 142. The cleaning brush 141 is arranged in close contact with the filter element 122 and is adapted to move along the surface of the filter element 122. The driving member 142 is arranged in the housing 110 and is in transmission connection with the cleaning brush 141 to drive the cleaning brush 141 to move. For example, the driving member 142 can include at least one of a micro motor, a step motor or a speed-reducing motor as a power source, and a gear set, a transmission rod, a belt or a lead screw 1433 and the like are used to transmit power to the cleaning brush 141 so that the cleaning brush 141 moves along the surface of the filter element 122 in a reciprocating linear motion, a rotary motion or a swing.

[0095] In this embodiment, during the operation of the cleaning device 100 or during the periodic stop gap, the electric control box 150 sends a control signal to start the driving member 142. The driving member 142 drives the cleaning brush 141 to move along the surface of the filter element 122, and the bristles of the cleaning brush 141 are in close contact with the surface of the filter element 122. During the movement, the filter element 122 is physically brushed to strip off the dirt such as silt, hair and algae attached to the surface of the filter element 122, so that the dirt is separated from the filter screen and sinks into the dust collecting area, thereby realizing the automatic cleaning function. Through the cooperative work of the cleaning brush 141 and the driving member 142, the automatic cleaning of the filter element 122 can be completed in the state that the cleaning device 100 does not stop or stops for a short time, which is beneficial to improve the continuous operation capability of the device and avoid the use interruption of the cleaning device 100 caused by manually dismounting and cleaning the filter element 122. At the same time, by starting the cleaning brush 141 regularly or on demand, the surface deposits of the filter element 122 can be timely removed, the water flow resistance can be reduced, the filtration flow and the suction efficiency can be maintained at a high level, and the cleaning device 100 can be ensured to be always in the best working state.

[0096] In some possible embodiments, the operation of the filter screen cleaning device 140 can be set as at least one of a timing trigger, a pressure difference sensing trigger (automatically started when the pressure difference before and after the filter 122 exceeds a threshold value), a trigger when the detection device arranged in the shell 110 detects that the filter is blocked, or a linkage operation with the suction device 130.

[0097] Referring to Figure 10 , Figure 15 , Figure 21 and Figure 22 , according to some embodiments of the present application, the filter screen cleaning device 140 further comprises a transmission mechanism 143 connected with the driving member 142 and the cleaning brush 141 respectively, the driving member 142 drives the cleaning brush 141 to move through the transmission mechanism 143, that is, the transmission mechanism 143 effectively transmits the power and motion form output by the driving member 142 to the cleaning brush 141 as a power transmission bridge, and the transmission mechanism 143 can include at least one of a gear and rack mechanism, a crank and connecting rod mechanism, a synchronous belt 1435 / chain mechanism, and a lead screw 1433 and nut mechanism. In this way, the speed reduction, speed increase, direction change, or motion form conversion (such as rotation → straight line) of the cleaning brush 141 is realized to adapt to different cleaning path and speed requirements on the filter 122.

[0098] In the present embodiment, when the system needs to perform a filter screen cleaning operation, the electric control box 150 issues an instruction to start the driving member 142 (such as a micro motor). The driving member 142 outputs a rotating power, which is transmitted to the cleaning brush 141 through the transmission mechanism 143 to drive the cleaning brush 141 to move along the surface of the filter 122 in a predetermined track. According to design requirements, the transmission mechanism 143 can convert the rotating motion of the driving member 142 into reciprocating linear motion, rotating motion, or swinging motion of the cleaning brush 141, to ensure that the bristles fully cover the effective filtering area of the filter 122 and complete efficient cleaning.

[0099] Referring to Figure 2 , according to some embodiments of the present application, the shell 110 is further provided with a second accommodating cavity 112, the second accommodating cavity 112 is arranged side by side with the first accommodating cavity 111 along the first direction, the second accommodating cavity 112 is located outside the first accommodating cavity 111, and the overflow port 111b is arranged on the cavity wall between the first accommodating cavity 111 and the second accommodating cavity 112, in other words, the overflow port 111b is arranged on the side cavity wall of the first accommodating cavity 111 facing the second accommodating cavity 112, so that the first accommodating cavity 111 is in communication with the second accommodating cavity 112 through the overflow port 111b, and the suction device 130 and the electric control box 150 are arranged in the second accommodating cavity 112.

[0100] During the cleaning process, the external contaminated fluid enters the dust collecting device 120 in the first accommodating cavity 111 through the contaminated fluid inlet 111a, and is subjected to solid-liquid separation through the filter 122. The filtered cleaning fluid flows into the second accommodating cavity 112 adjacent to the first accommodating cavity 111 through the flow port 111b in the side wall of the first accommodating cavity 111. Since the suction device 130 (such as a water pump or a fan) is arranged in the second accommodating cavity 112, the inlet of the suction device 130 is connected with the flow port 111b or is connected through a short pipe, so that a negative pressure can be formed in the second accommodating cavity 112, the filtered fluid from the first accommodating cavity 111 is continuously sucked, and the filtered fluid is pressurized and discharged into the swimming pool or the external environment.

[0101] At the same time, the electric control box 150 for supplying power and controlling the entire system is also integrated in the second accommodating cavity 112, away from the area directly washed by the water flow, to ensure electrical safety. The two accommodating cavities are connected in series through the flow port 111b in the fluid channel, and are relatively isolated in physical space, forming a functional division layout of “pre-filtering—post-power and control”.

[0102] In this way, the filtering area (the first accommodating cavity 111) susceptible to contamination is physically isolated from the precise power and electrical components (the second accommodating cavity 112), effectively preventing sewage and impurities from entering the electric control box 150 or the suction device 130, and is beneficial to improve the waterproof, dustproof and anti-interference ability of the cleaning equipment 100.

[0103] Reference Figure 5a , Figure 5b , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 14 , Figure 18 , Figure 19 and Figure 20 According to some embodiments of the present application, the filter 122 at least partially surrounds the filtering cavity 121. For example, the filter 122 can partially surround the filtering cavity 121, and the filter 122 can cover at least the portion of the filtering cavity 121 corresponding to the flow port 111b (such as Figure 5b , Figure 13 and Figure 14As shown in FIG. 1, FIG. 2, and FIG. 3, the filter 122 can be formed as a boundary structure of the filter cavity 121, arranged in a non-planar form such as an arc shape, a cylindrical shape, or an L shape, at least partially surrounding the filter cavity 121 (for example, the filter 122 can wrap around the wall of the filter cavity 121 by 180°, 270°, or 360°), and covering at least the flow port 111b. That is, the filter 122 is arranged on the wall of the dust collection device 120 corresponding to the flow port 111b on the middle frame 1102, so that the fluid entering from the dirt inlet 111a must flow through the filter 122 covering the flow port 111b before being discharged from the dust collection device 120, thereby achieving efficient interception of dirt. Alternatively, the filter 122 can also surround the entire filter cavity 121 (as shown in FIG. 4), so that the fluid entering the filter cavity 121 must flow through the filter 122 before being discharged from the dust collection device 120, thereby achieving efficient interception of dirt. Figure 6 and Figure 7 As shown in FIG. 1, FIG. 2, and FIG. 3, the filter 122 can be formed as a boundary structure of the filter cavity 121, arranged in a non-planar form such as an arc shape, a cylindrical shape, or an L shape, at least partially surrounding the filter cavity 121 (for example, the filter 122 can wrap around the wall of the filter cavity 121 by 180°, 270°, or 360°), and covering at least the flow port 111b. That is, the filter 122 is arranged on the wall of the dust collection device 120 corresponding to the flow port 111b on the middle frame 1102, so that the fluid entering from the dirt inlet 111a must flow through the filter 122 covering the flow port 111b before being discharged from the dust collection device 120, thereby achieving efficient interception of dirt. Alternatively, the filter 122 can also surround the entire filter cavity 121 (as shown in FIG. 4), so that the fluid entering the filter cavity 121 must flow through the filter 122 before being discharged from the dust collection device 120, thereby achieving efficient interception of dirt.

[0104] In the direction of fluid flow, dirt is usually intercepted by the filter 122 on the surface corresponding to the flow port 111b. The filter screen cleaning device 140 is adapted to clean at least part of the surface of the filter 122, that is, the filter screen cleaning device 140 is at least adapted to clean the surface of the filter 122 corresponding to the flow port 111b, or the filter screen cleaning device 140 can also clean the entire surface of the filter 122.

[0105] According to some embodiments of the present application, the filter 122 includes a first filter surface 1220 facing the flow port 111b in a first direction, which is the core working area of the filter 122 and undertakes the main filtering task. The first filter surface 1220 can be a planar, arc, or inclined surface structure, and is made of high water permeable filter screen or microporous material.

[0106] The filter screen cleaning device 140 is movable relative to the first filter surface 1220 to clean the first filter surface 1220, that is, the cleaning brush 141 of the filter screen cleaning device 140 is configured to match the surface profile of the first filter surface 1220, and under the action of the driving member 142, the cleaning brush 141 brushes the surface of the first filter surface 1220.

[0107] In the present embodiment, the fluid carrying dirt enters the filter cavity 121 from the dirt inlet 111a and flows to the flow port 111b under the action of the negative pressure generated by the suction device 130.

[0108] It can be understood that the dust collecting device 120 can be arranged spaced apart from the cavity wall of the first containing cavity 111 (i.e., the inner wall of the middle frame 1102), that is, under the action of the negative pressure generated by the suction device 130 towards the overflow port 111b, the fluid can flow out along the wall surface of the dust collecting device 120 opposite to the inner wall of the first containing cavity 111, and flow to the overflow port 111b from the gap between the wall surface of the dust collecting device 120 and the inner wall of the first containing cavity 111.

[0109] Since the first filtering surface 1220 is located on the flow path of the fluid and faces the overflow port 111b, correspondingly, the suction effect on the fluid passing through the first filtering surface 1220 is stronger, and the clogging condition is more likely to occur.

[0110] As the running time is prolonged, the first filtering surface 1220 accumulates dirt, resulting in a decrease in the flow capacity. At this time, the filter screen cleaning device 140 is started, and the cleaning brush 141 moves relative to the surface of the first filtering surface 1220, which can be reciprocating sliding, rotating rolling or profile scanning movement. The cleaning brush 141 continuously scrapes or brushes the first filtering surface 1220, peels off the attached dirt and washes it away with the water flow, thereby restoring the filtering performance.

[0111] Reference Figure 5a , Figure 5b , Figure 6 and Figure 7 According to some embodiments of the present application, the filter 122 includes an inner filtering layer 122a and an outer filtering layer 122b spaced apart from each other, and the filtering accuracy of the inner filtering layer 122a and the outer filtering layer 122b is different. In fact, the filtering accuracy is related to the number of filtering holes on the inner filtering layer 122a and the outer filtering layer 122b, and the higher the number, the higher the filtering accuracy. The filtering accuracy of the inner filtering layer 122a and the outer filtering layer 122b is different, that is, the number of filtering holes of the inner filtering layer 122a and the outer filtering layer 122b is different. The number of the inner filtering layer 122a and the outer filtering layer 122b can be flexibly adjusted according to the filtering requirement.

[0112] One of the inner filtering layer 122a and the outer filtering layer 122b is used for fine filtering, and the other is used for coarse filtering. Exemplarily, the inner filtering layer 122a can be used for fine filtering, and the outer filtering layer 122b can be used for coarse filtering, or the inner filtering layer 122a can be used for coarse filtering, and the outer filtering layer 122b can be used for fine filtering.

[0113] Reference Figure 18 , Figure 19 and Figure 20The filter screen cleaning device 140 is used to clean the first filter surface 1220 of one of the inner filter layer 122a and the outer filter layer 122b used for fine filtration. For example, when the inner filter layer 122a is the fine filtration layer, the cleaning brush 141 can be arranged on the inner surface of the filter element 122 or between the inner filter layer 122a and the outer filter layer 122b to clean the inner filter layer 122a and / or the outer filter layer 122b. When the outer filter layer 122b is the fine filtration layer, the cleaning brush 141 can be arranged between the inner filter layer 122a and the outer filter layer 122b to clean the outer surface of the inner filter layer 122a and / or the inner surface of the outer filter layer 122b.

[0114] In this way, the filter element 122 is formed in a double-layer structure with an inner layer and an outer layer arranged in a spaced-apart manner, one layer for coarse filtration (intercepting large-particle impurities such as leaves, hair, and sand) and the other layer for fine filtration (intercepting small particles such as algae, dust, and colloidal substances), forming a multi-stage filtration system. The filter screen cleaning device 140 is specifically used to clean the first filter surface 1220 of the layer used for fine filtration, ensuring the continuous and stable high-precision filtration function.

[0115] The double-layer structure of the filter element 122 forms a “coarse filtration + fine filtration” synergistic mechanism, which is beneficial to effectively share the filtration load, prevent the fine filtration layer from being clogged too early, and significantly prolong the continuous operation time of the cleaning device 100 between two cleanings. At the same time, the multi-stage filtration is beneficial to improve the removal rate of impurities of different particle sizes, so that the cleaning device 100 is suitable for pool environments with complex water quality and various impurities, the effluent is clearer, and the burden on the subsequent water treatment system is reduced.

[0116] According to some embodiments of the present application, the outer filter layer 122b is used for fine filtration, and the inner filter layer 122a is used for coarse filtration. After the contaminated fluid enters the filter cavity 121 from the contaminated fluid inlet 111a, it first passes through the inner filter layer 122a (performing coarse filtration) to remove larger impurities such as hair, sand, leaf fragments, etc., and then passes through the outer filter layer 122b (performing fine filtration) to intercept small particles such as dust, algae, and colloids, and is discharged into the second containing cavity 112 through the overflow port 111b. The contaminants are filtered in order from large to small in volume along the flow direction of the fluid, which reduces the filtration pressure of the filter element 122, and at the same time, the larger impurities filtered by the coarse filter are left in the filter cavity 121 for easy cleaning.

[0117] The filter screen cleaning device 140 is arranged between the outer filter layer 122b and the inner filter layer 122a, so that its working environment is relatively clean (the filtered part of the water flow), avoiding direct contact with large-particle impurities from the contaminated fluid inlet 111a, reducing the wear and blockage of the brush body, and being beneficial to prolong the service life of the filter screen cleaning device 140.

[0118] The dust collecting device 120 comprises a filter support 123, which comprises an outer support 123b and an inner support 123a. The outer support 123b can be a frame structure capable of enclosing a certain space, and is used for mounting the outer filter layer 122b. The inner support 123a is used for mounting the inner filter layer 122a, and can be a partition structure inside the outer support 123b, or a frame structure nested with the outer support 123b.

[0119] The bottom of the filter support 123 is provided with a collection bin 124, which is located below the cleaning brush 141. In this way, the dirt scraped off by the cleaning brush 141 from the inner side naturally falls under the action of gravity and is effectively stored in the collection bin 124 below, avoiding re-suspension into the water flow or clogging the filter cavity 121.

[0120] In some embodiments, the portions of the inner support 123a and / or the outer support 123b adjacent to the bottom are formed as solid structures, and the solid structures of the inner support 123a and the outer support 123b together define the collection bin 124.

[0121] Exemplarily, the collection bin 124 can be a structure matched with the configuration of the bottom wall of the first containing cavity 111, and is located at the bottom of the first containing cavity 111. The collection bin 124 can be formed as a double-layer structure, in which the bottom of the inner support 123a constitutes an inner layer of the collection bin 124, the bottom of the outer support 123b constitutes an outer layer of the collection bin 124, and the inner layer and the outer layer of the collection bin 124 are in communication. Alternatively, the bottom of the outer support 123b extends to form the collection bin 124, and the bottom of the outer support 123b forms a link support structure. The bottom of the filter support 123 naturally forms the collection bin 124 without the need for an additional dirt collection cavity, thereby improving the utilization rate of the internal space of the shell 110. Meanwhile, the inner support 123a and the outer support 123b are designed in an integrated manner, thereby enhancing the structural strength.

[0122] In other embodiments, a dirt collection container can also be separately provided, which is located inside the filter cavity 121 and below the filter screen cleaning device 140, and defines the collection bin 124. In this case, the bottom of the dirt collection container and the bottom of the filter support 123 can be detachably connected (such as threaded connection or clamping, etc.). Alternatively, a reversible dirt discharge plate can also be provided at the bottom of the collection bin 124 to facilitate cleaning of the collected pollutants.

[0123] Reference Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14According to some embodiments of the present application, the transmission mechanism 143 comprises a swing arm 1431 having a first end 1431a and a second end 1431b, the first end 1431a of the swing arm 1431 is connected with the driving member 142 to swing back and forth under the driving of the driving member 142, and the cleaning brush 141 is arranged at the second end 1431b and is adapted to swing back and forth with the swing arm 1431.

[0124] In the present embodiment, the driving member 142 (such as a micro DC motor or a stepping motor) receives the control signal sent by the electric control box 150 and starts to operate. The output shaft 1421 of the driving member 142 is connected with the first end 1431a of the swing arm 1431 through an eccentric wheel, a crank or direct articulation, and converts the rotary motion into the reciprocating swing of the swing arm 1431.

[0125] The swing arm 1431 swings back and forth within a certain angle range with the fixed fulcrum (such as the rotating shaft 1432 of the driving member 142 or a hinge) as the center under the driving of the driving member 142. Since the cleaning brush 141 is fixed to the second end 1431b of the swing arm 1431, the cleaning brush 141 swings back and forth in an arc shape synchronously, and sweeps the inner surface of the outer filter layer 122b (i.e., the first filter surface 1220 for fine filtration) closely, thereby achieving the periodic brushing of the key area of the filter element 122.

[0126] In this way, the cleaning brush 141 swings in a circular arc with the swing arm 1431, and the motion track naturally matches the inner surface of the cylindrical or arc-shaped outer filter layer 122b, so that the bristles are always in contact with the filter screen and the cleaning is free of dead angles. The swing arm 1431 mechanism can achieve a larger cleaning coverage in a smaller installation space, and is suitable for being arranged in the narrow interlayer space between the outer filter layer 122b and the inner filter layer 122a, and fully utilizes the limited gap space.

[0127] In some possible embodiments, the swing arm 1431 and the cleaning brush 141 can be connected through a buckle, a thread or a quick release structure, so that the user can easily replace the worn brush head and prolong the service life of the cleaning device 100.

[0128] In some possible embodiments, the cleaning brush 141 can be arranged along the length direction of the swing arm 1431 to form a long strip structure (such as shown in Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 ). Figure 4 Figure 6 In some possible embodiments, the cleaning brush 141 can be arranged along the length direction of the swing arm 1431 to form a long strip structure (such as shown in

[0129] Reference​Figure 2 、 Figure 10 、 Figure 11 、 Figure 15 and Figure 16 According to some embodiments of the present application, the dust collecting device 120 comprises a filter support 123, which is hollow, for example, the filter support 123 can be a mesh, grid or skeleton structure, which not only provides sufficient structural strength to support the filter 122, but also ensures that the fluid can pass freely without hindering the water flow. The hollow design helps to reduce the overall weight of the cleaning device 100, reduce material cost, and prolong the operating time of the cleaning device 100. The filter 122 is arranged in the hollow part of the filter support 123, and the filter 122 and the filter support 123 together define a filter cavity 121, which ensures that all filtered fluid is directed to the overflow port 111b and prevents bypass.

[0130] The driving member 142 is arranged outside the filter support 123 (such as the sidewall or bottom of the shell 110), away from the high-humidity and high-pollution interior of the filter cavity 121, which facilitates heat dissipation, wiring and maintenance, and at the same time avoids the problem of water entering the interior due to the failure of the motor seal. The driving member 142 has a rotatable output shaft 1421, which is used to transmit power to the cleaning brush 141.

[0131] The first end 1431a of the swing arm 1431 is provided with a rotating shaft 1432 extending in the first direction, which penetrates the filter support 123 and is connected with the output shaft 1421. For example, the rotating shaft 1432 can be connected with the output shaft 1421 through a coupling, spline or direct welding / injection molding. By penetrating the filter support 123 through the rotating shaft 1432, the external power is efficiently transmitted to the internal cleaning mechanism, without the need for additional holes on the shell 110, which simplifies the overall sealing design while maintaining a short and efficient transmission path.

[0132] According to some embodiments of the present application, the swing angle of the swing arm 1431 is 120°-360°, for example, the swing angle of the swing arm 1431 can be 120°, 150°, 180°, 210°, 240°, 270°, 300°, 330° or 360°. Of course, the swing angle of the swing arm 1431 can also be other values, which are not limited in the present application.

[0133] In the embodiment, when the swing angle of the swing arm 1431 is 120°-180°, the swing arm 1431 swings back and forth within a fixed angle range, and the cleaning brush 141 performs an arc-shaped reciprocating motion, covering the key filtering area (such as the area corresponding to the overflow port 111b) of the inner surface of the outer filter layer 122b. When the swing angle of the swing arm 1431 is greater than 180° (such as 240° or 300°) or reaches 360°, the swing arm 1431 can realize large-range sweeping or even full-circle rotation, so that the motion track of the cleaning brush 141 covers a wider area, and is particularly suitable for comprehensive cleaning of the cylindrical or annular first filtering surface 1220.

[0134] Reference Figure 15 、 Figure 17 、 Figure 18 、 Figure 19 、 Figure 20 、 Figure 21 and Figure 22 According to some embodiments of the present application, the transmission mechanism 143 includes a lead screw 1433 and a sliding mounting 1434.

[0135] The lead screw 1433 extends along a second direction perpendicular to the first direction, is connected with the driving member 142, and is adapted to rotate under the driving of the driving member 142, converting the rotary motion of the driving member 142 into the linear motion of the sliding mounting 1434. The lead screw 1433 can include at least one of a screw rod, a trapezoidal lead screw 1433, or a ball screw 1433.

[0136] The sliding mounting 1434 is sleeved on the lead screw 1433 and threadedly cooperates with the lead screw 1433, and is adapted to move along the second direction under the driving of the lead screw 1433. The cleaning brush 141 is arranged on the sliding mounting 1434. At this time, the sliding mounting 1434 is formed as a threaded sleeve. When the driving member 142 drives the lead screw 1433 to rotate, the sliding mounting 1434 drives the cleaning brush 141 to move along the second direction, and the cleaning brush 141 moves along the second direction (perpendicular to the first direction), so that the motion track of the cleaning brush 141 is orthogonal to the main flow channel, improving the cleaning uniformity.

[0137] At this time, it should be noted that the second direction can be the Z direction, and the cleaning brush 141 slides along the height direction, or the second direction can also be the Y direction, and the cleaning brush 141 slides along the front-rear direction (or the left-right direction) of the shell 110 to clean the first filtering surface 1220.

[0138] Thus, the lead screw 1433 has the advantages of high transmission accuracy and accurate repeat positioning, and the cleaning brush 141 can be accurately moved along a set path to ensure comprehensive and non-missing linear scanning of the first filter surface 1220. The lead screw 1433 has continuous transmission, small impact, quiet operation, and is suitable for a noise-sensitive home environment; meanwhile, the lead screw 1433 has small wear and long service life.

[0139] It can be understood that the first accommodating cavity 111 or the filter cavity 121 is provided with a limiting structure (such as a guide rod, a guide rail or a limiting groove), and the sliding mounting member 1434 is connected with the limiting structure to avoid rotation of the sliding mounting member 1434 with the lead screw 1433, and to facilitate improvement of operation reliability of the cleaning device 100.

[0140] According to some embodiments of the present application, the lead screw 1433 is a reciprocating lead screw, and the lead screw 1433 is driven by the driving member 142 to rotate in one direction and drive the sliding mounting member 1434 to move reciprocally in the second direction. Exemplarily, the lead screw 1433 is processed with a helical groove of a specific lead, and the helical groove is provided with a reversible mechanism (such as an internal ball circulation sleeve or a mechanical cam reverser) which can slide.

[0141] When the driving member 142 (such as a direct current motor) drives the reciprocating lead screw to rotate in one direction, the sliding mounting member 1434 (as a nut) is engaged with the lead screw 1433 through internal threads and can only move linearly in the second direction due to the limitation of the guide structure, and the sliding mounting member 1434 moves at a constant speed along the axial direction of the lead screw 1433 with the rotation of the lead screw 1433. When the sliding mounting member 1434 reaches the preset stroke end point of the lead screw 1433 (triggered by the built-in reversing structure), the reversing mechanism automatically changes the thread engagement path to force the sliding mounting member 1434 to automatically move in the reverse direction without reversing the lead screw 1433. The sliding mounting member 1434 returns along the original path and automatically reverses again after reaching the starting end to form continuous reciprocating linear motion. The cleaning brush 141 connected with the sliding mounting member 1434 is synchronously reciprocated to periodically and fully cover the linear scanning and cleaning of the first filter surface 1220 of the filter 122.

[0142] Since the driving member 142 only needs to rotate in one direction, the control box 150 does not need to send forward and reverse rotation instructions, and the complex reversing control logic and driving circuit are omitted, the cost of the control module is significantly reduced, and the system stability is improved. The problems of motor overheating, gear wear or control out-of-step caused by frequent start-stop or forward and reverse rotation are avoided; the mechanical reversing mechanism of the reciprocating lead screw has long service life and reliable action, and is suitable for long-term continuous operation. The sliding mounting member 1434 moves at a constant speed under the driving of the reciprocating lead screw, the reversing process is smooth and has no impact, the cleaning force of the cleaning brush 141 on the filter 122 is uniform, and local excessive wear or insufficient cleaning of the filter 122 is avoided.

[0143] Reference Figure 22According to some embodiments of the present application, the inner filter layer 122a is provided with a mounting plate 1436 extending along the second direction, which serves as a structural support and is fixed to the inner filter layer 122a to provide a mounting reference.

[0144] One end of the mounting plate 1436 along the second direction is provided with a through hole 14361 extending along the third direction, which is used for passing the synchronous belt 1435 to form a mechanical connection passage.

[0145] The cleaning brush 141 and the sliding mounting member 1434 are respectively located on both sides of the mounting plate 1436 along the third direction, which physically isolates the transmission mechanism 143 from the cleaning execution area, avoids the large-volume sliding mounting member 1434 from occupying the filter cavity 121 or obstructing water flow, and optimizes the utilization of internal space.

[0146] The transmission mechanism 143 further includes a synchronous belt 1435 passing through the through hole 14361, one end of the synchronous belt 1435 being connected with the sliding mounting member 1434, and the other end being connected with the cleaning brush 141, so that when the lead screw 1433 drives the sliding mounting member 1434 to move, the sliding mounting member 1434 drives the cleaning brush 141 to move through the synchronous belt 1435.

[0147] In this embodiment, when the lead screw 1433 is driven by the driving member 142 to rotate unidirectionally, the sliding mounting member 1434 threaded with the lead screw 1433 reciprocates along the second direction. This movement is transmitted to the cleaning brush 141 through the synchronous belt 1435, which drives the cleaning brush 141 to reciprocate along the second direction on the other side of the mounting plate 1436, thereby performing linear scanning cleaning on the first filter surface 1220 of the filter 122. Since the synchronous belt 1435 has flexibility and accurate transmission, its stretching and deformation is extremely small, which can ensure that the movement of the cleaning brush 141 and the sliding mounting member 1434 is completely synchronized, achieving high-precision linkage.

[0148] According to some embodiments of the present application, the cleaning brush 141 is formed in at least one of a fan shape, a straight line shape, and a V shape.

[0149] Reference Figure 9 and Figure 10 For example, the cleaning brush 141 can be formed in a fan shape, the brush body being a circular arc fan shape with a curvature matching the inner surface of the filter 122, and the bristles being arranged in a radial direction. The cleaning brush 141 performs arc-shaped reciprocating swing under the driving of the swing arm 1431, and its movement trajectory highly matches the arc-shaped filter surface, which ensures that the bristles always vertically or approximately vertically contact the filter screen surface, thereby improving cleaning uniformity. It is suitable for arc / sleeve-shaped filters 122 that are surrounded or partially surrounded, and is particularly suitable for the swing arm 1431 type transmission mechanism 143.

[0150] Reference Figure 12 , Figure 13 ,Figure 14 、 Figure 15 、 Figure 17 、 Figure 18 and Figure 22 , or the cleaning brush 141 can also be a straight line structure, the brush body of the cleaning brush 141 is in a straight line shape, and the bristles are uniformly distributed on one side or both sides of the base body, and the overall rigidity or flexibility can be adjusted. With the linear reciprocating movement of the sliding mounting member 1434 or the swing arm 1431 in the second direction (such as the vertical direction), the filter surface is cleaned in a linear scanning manner. It is suitable for flat or small curvature filter surfaces, especially with the lead screw 1433-synchronous belt 1435 transmission mechanism 143, to realize row-by-row brushing.

[0151] Referring to Figure 21 , or the cleaning brush 141 can also be a V-shaped structure, the brush body is in a "V" shape, the included angle between the two arms can be 30°-120°, and the bristles are distributed on the inner side or the peripheral wall. The V-shaped structure forms a converging cleaning path, and during reciprocating movement, the dirt is "squeezed" from both sides to the center and slides down to the collection bin 124 below; this cleaning brush structure not only applies to cleaning flat filter structures, but also can cover two directions of filter surfaces at the same time (by adjusting the included angle between the two arms of the V-shaped structure and the direction, as shown in Figure 29 ).

[0152] Referring to Figure 23 、 Figure 24 、 Figure 25 、 Figure 26 and Figure 29 , according to some embodiments of the present application, the suction device 130 is arranged in the first containing cavity 111, at this time, the outer wall of the impeller cover 131 and the inner wall of the middle frame 1102 jointly define the first containing cavity 111, and the exhaust passage 133 on the inner side of the impeller cover 131 can be used as the second containing cavity 112, the overflow port 111b is arranged at the bottom of the impeller cover 131, so that the second containing cavity 112 is in communication with the first containing cavity 111 in the middle frame 1102, and the electric control box 150 is arranged in the space below the first containing cavity 111, in other words, the dust collecting device 120 and the electric control box 150 are arranged in layers. In this way, it is beneficial to fully utilize the internal space of the shell 110 in the height direction, reduce the lateral expansion of the shell 110, and improve the passability and flexibility of the cleaning equipment 100 in a small space.

[0153] Continuing to refer to Figure 27 、 28According to some embodiments of the present application, the filter 122 comprises an inner filter layer 122a and an outer filter layer 122b, which are arranged in a sleeve structure from the outside of the suction device 130 inwards, and the inner filter layer 122a forms the inner boundary of the filter cavity 121, and the outer filter layer 122b forms the outer boundary of the filter cavity 121. In the filter cavity 121, the fluid is transported to the suction device 130 through the outer filter layer 122b or the inner filter layer 122a, and is discharged from the housing 110. The filter 122 is arranged around the suction device 130 in a "covering" manner, forming a concentric nested structure, which is conducive to improving the space utilization inside the housing 110.

[0154] It can be understood that the inner filter layer 122a and the outer filter layer 122b together surround the filter cavity 121 to form a fluid collection area, ensuring that all filtered water flows to the inlet of the suction device 130, and also allowing the outer periphery of the suction device 130 to be surrounded by the filter cavity 121 to directly suck in the filtered cleaning fluid, avoiding impurities from entering the pump body to cause wear or blockage, which is conducive to improving the suction efficiency and prolonging the service life of the cleaning equipment 100.

[0155] The filter screen cleaning device 140 is arranged in the filter cavity 121, and the filter screen cleaning device 140 is used for cleaning at least one of the inner filter layer 122a and the outer filter layer 122b. For example, the filter screen cleaning device 140 can be used for cleaning the inner filter layer 122a (a cleaning brush 141 is arranged inside the inner filter layer 122a or between the inner filter layer 122a and the outer filter layer 122b), or the filter screen cleaning device 140 can be used for cleaning the outer filter layer 122b (a cleaning brush 141 is arranged outside the outer filter layer 122b or between the inner filter layer 122a and the outer filter layer 122b), or the filter screen cleaning device 140 can be used for cleaning the inner filter layer 122a and the outer filter layer 122b at the same time (a cleaning brush 141 is arranged inside the inner filter layer 122a and outside the outer filter layer 122b, or a cleaning brush 141 is arranged between the inner filter layer 122a and the outer filter layer 122b to clean the inner filter layer 122a and the outer filter layer 122b at the same time). In this way, a compact, efficient, and self-cleaning filter system is formed, which not only effectively protects the suction device 130, but also ensures the continuous and efficient operation of the filter 122 through the built-in cleaning mechanism, which is conducive to improving the continuous reliability of the filtering effect.

[0156] Further, the outer filter layer 122b and the cavity wall of the first containing cavity 111 can be spaced apart to form a filter gap, and the filter gap is in communication with the overflow port 111b, thereby providing a channel for the fluid to pass through the outer filter layer 122b, the filter gap, and the overflow port 111b, which is conducive to improving the filtering efficiency of the filter 122.

[0157] Reference is made to Figure 23 and Figure 26 According to some embodiments of the present application, the inner filter layer 122a is cylindrical, providing a regular circumferential geometric surface, facilitating the cleaning brush 141 to achieve uniform adhesion and continuous track coverage. The driving member 142 is adapted to drive the cleaning brush 141 to rotate around the circumference of the inner filter layer 122a. Exemplarily, the cleaning brush 141 can be an arc-shaped brush or a straight brush, rotating to brush the inner filter layer 122a in a posture adapted to the curvature of the cylinder, so as to clean the inner filter layer 122a. In this way, the cleaning brush 141 rotates around the circumference of the cylindrical inner filter layer 122a, which can completely sweep the entire outer surface and thoroughly remove the circumferentially deposited dirt, especially suitable for cleaning the annular dirt belt formed on the filter 122 after the cleaning device 100 is operated for a long time.

[0158] Reference is made to Figure 27 and Figure 28 In other embodiments of the present application, the inner filter layer 122a can have a variable shape, such as a triangle, quadrilateral, pentagon, hexagon, etc. In this case, the structure of the cleaning brush 141 can be adaptively matched with the contour of the inner filter layer 122a. Alternatively, the inner filter layer 122a can also have an elliptical structure, and the structure of the cleaning brush 141 can be adaptively matched with the contour of the inner filter layer 122a. Reference is made to Figure 29 and Figure 30 According to some embodiments of the present application, the cleaning brush 141 is formed in a spiral shape extending around the axis of the inner filter layer 122a, extending from the top to the bottom of the inner filter layer 122a. In this way, when the driving member 142 starts and drives the cleaning brush 141 to rotate around the circumference of the inner filter layer 122a, since the cleaning brush 141 itself is in a spiral shape, it will sequentially sweep every area of the outer surface of the inner filter layer 122a during rotation. That is, each turn of the spiral cleaning brush 141 corresponds to an axial position of the inner filter layer 122a, and as the cleaning brush 141 rotates as a whole around the axis, the bristles of the cleaning brush 141 move in the circumferential direction while its spiral trajectory naturally covers the entire cylindrical surface from top to bottom, which is equivalent to completing the "continuous brushing" of the entire cylindrical first filter surface 1220 in one complete rotation, without reciprocating motion or multi-stroke operation. This process can be achieved by one-way continuous rotation of the motor, and the cleaning brush 141 dynamically brushes the surface of the filter 122 like a "spiral propeller", effectively removing the attached dirt, algae, biofilm, etc.

[0159] Reference is made to Figure 29 and Figure 30According to some embodiments of the present application, the transmission mechanism 143 comprises a cleaning bracket 1437, which serves as a bearing matrix for the cleaning brush 141 and provides rigid support for the cleaning brush 141. The cleaning bracket 1437 is arranged on the outside of the inner filter layer 122a, ensuring that the cleaning bracket 1437 is coaxially arranged with the inner filter layer 122a, improving the motion stability of the cleaning brush 141, and the cleaning brush 141 is arranged on the inner wall of the cleaning bracket 1437.

[0160] The outer periphery of the cleaning bracket 1437 is provided with a rack structure extending in the circumferential direction of the inner filter layer 122a, and the driving member 142 has an output gear that is engaged with the rack to drive the cleaning bracket 1437 to rotate the cleaning brush 141. When the driving member 142 is started, the output gear rotates, driving the rack to move in the circumferential direction, thereby rotating the entire cleaning bracket 1437 around the axis of the inner filter layer 122a, and the helical cleaning brush 141 fixed to the inner wall of the cleaning bracket 1437 rotates synchronously, continuously sweeping the outer surface of the inner filter layer 122a in a helical manner.

[0161] In this way, the cleaning bracket 1437 is formed as a whole bearing structure, avoiding the problem of single cleaning brush 141 cantilever installation being prone to shaking, and the cleaning bracket 1437 rotates uniformly, with little vibration and low noise. At the same time, the cleaning bracket 1437 and the driving member 142 are engaged by the gear and the rack, without slipping, so that the rotation angle of the cleaning bracket 1437 strictly corresponds to the driving signal, thereby making the motion trajectory of the helical cleaning brush 141 highly predictable and the cleaning uniform.

[0162] In some possible embodiments, the cleaning bracket 1437 can be a circular ring structure extending in the circumferential direction of the inner filter layer 122a, or the cleaning bracket 1437 can also be a circular arc structure extending in the circumferential direction of the inner filter layer 122a.

The cleaning device 100 in the pool can be docked on the bearing member, and the bearing member and the support member cooperate to perform operations such as charging, cleaning of the filter device, garbage recycling, and chemical replenishment on the cleaning device 100.

The base station 210 is further provided with a water drainage channel, the water drainage channel communicates with the internal space of the third accommodating cavity of the support, and the liquid filtered by the second filtering assembly flows out of the base station 210 through the water drainage channel, such as flowing into a water pool through the water drainage channel, or flowing to the bank of the water pool through the water drainage channel, or flowing to a sewer, etc.

[0166] The cleaning system 200 of the present application uses the cleaning device 100 described above, when working in the pool, the filter screen cleaning device 140 built in the cleaning device 100 can perform online self-cleaning on the filtering element 122, prevent the filter screen from being blocked during operation, and maintain high-efficiency filtering; after the task is completed or returned to the base station 210, the base station 210 automatically performs centralized deslagging and deep flushing on the dust collection device 120, and removes stubborn dirt accumulated for a long time. The double cleaning mechanism ensures that the filtering system is always in the best working state and avoids performance degradation.
