Description

Technical Field

[0001] This application relates to cleaning equipment manufacturing technology, and more particularly to a cleaning equipment. Background Technology

[0002] With economic development and continuous social progress, intelligent cleaning equipment has gradually entered people's lives, providing them with numerous conveniences. Cleaning equipment (such as pool cleaning robots) can clean the bottom, walls, surface, or waterline of pools, greatly reducing the labor intensity of cleaning pools.

[0003] When cleaning the pool wall, the cleaning equipment needs to move along the pool wall; at the same time, the water pump inside the cleaning equipment is working. When the water pump discharges the filtered water from the cleaning equipment, it can apply a counterforce to the cleaning equipment, thereby making the cleaning equipment stick tightly to the pool wall and preventing it from falling.

[0004] However, when the filter components inside the cleaning equipment become clogged, the amount of water discharged by the pump decreases, and the corresponding counterforce applied to the cleaning equipment also decreases, thus posing a risk of the cleaning equipment falling. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the related technologies, the purpose of this application is to provide a cleaning device that can improve the water inlet and outlet flow of the water pump assembly, thereby increasing the reverse force applied to the cleaning device and reducing the risk of the cleaning device falling.

[0006] This application provides a cleaning device, including a housing, a receiving cavity formed inside the housing, a filter assembly and a water pump assembly disposed in the receiving cavity, and a water inlet and a water outlet disposed on the housing. The water inlet is connected to the filter assembly, and the water pump assembly is connected to the filter assembly and the water outlet.

[0013] When the cleaning equipment is at the bottom of the pool or in a near-horizontal position, the first control panel can block all the first through holes.

[0014] In one possible implementation, a baffle is also provided on the dust bin, the baffle being detachably connected to the dust bin and located on the side of the first through hole facing away from the first control board.

[0016] In one possible implementation, the second control panel includes a second body and a second counterweight, with a first end of the second body rotatably connected to the side wall of the outer dust box, and the second counterweight disposed at the second end of the second body.

[0017] When the cleaning equipment moves from the bottom of the pool to the pool wall, the second counterweight can drive the second control plate to rotate to at least partially open the second through hole;

[0018] When the cleaning equipment is at the bottom of the pool or in a near-horizontal position, the second control panel can block all the second through holes.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0057] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0058] As described in the background section, in the related technical solutions, if the internal filter components become clogged when the cleaning equipment is cleaning the pool wall, the drainage volume of the water pump will decrease, and the corresponding reverse force applied to the cleaning equipment will also decrease, thereby posing a risk of the cleaning equipment falling.

[0059] In view of this, the present application aims to provide a cleaning device. By setting a flow regulating mechanism on the filter assembly, when the cleaning device moves from the bottom of the pool to the pool wall, or when the cleaning device moves on the pool wall, the filter assembly can be connected to the water pump assembly through the flow regulating mechanism, thereby increasing the amount of water flowing from the filter assembly to the water pump assembly and providing the amount of water discharged from the outlet of the cleaning device. This is beneficial to increase the reverse force applied to the cleaning device and reduce the risk of the cleaning device falling off the pool wall.

[0060] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the content of this application. It should be noted that, in the description of this embodiment, the first direction X, the second direction Y, and the third direction Z are three different directions in three-dimensional space. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other, and the third direction Z can be the height direction of the outer casing. It is understood that, in the embodiments of this application, to facilitate the description of the positional relationships of the internal components of the device, a three-dimensional coordinate system is established with the machine center as the origin, such as... Figure 1 As shown, the X, Y, and Z directions are used to describe the machine's own orientation. For example, the machine handle is located in the positive X-axis direction, and the handle is always located in the positive X-axis direction regardless of the machine's posture.

[0061] Please refer to Figure 1 and Figure 2This embodiment provides a cleaning device, such as a pool cleaning robot or a water tank cleaning robot. The cleaning device includes a housing 1000, within which a receiving cavity 1100 is formed. One end of the housing 1000 may also be provided with an end cap, which covers the housing 1000 and conceals the receiving cavity 1100. The user can expose or conceal the receiving cavity 1100 by opening or closing the end cap. The receiving cavity 1100 provides space for the installation of other components; exemplarily, in this embodiment, the receiving cavity 1100 contains a filter assembly 2000 and a water pump assembly 3000.

[0062] The outer casing 1000 is also equipped with an inlet 1200 and an outlet 1300. The inlet 1200 is connected to the filter assembly 2000, and the water pump assembly 3000 is connected to the filter assembly 2000 and the outlet 1300. The water pump assembly 3000 is used to drive external water flow from the inlet 1200 through the filter assembly 2000 to the outlet 1300. Specifically, as shown... Figure 1 and Figure 2 As shown, the water inlet 1200 of this embodiment includes a first water inlet 1210 disposed on the bottom wall 1010 of the outer casing. In some embodiments, the water inlet 1200 may also include a second water inlet 1220 disposed on the side wall 1020 of the outer casing. The water outlet 1300 is disposed on the end cap. The first water inlet 1210 and the water outlet 1300 are disposed opposite each other along the third direction Z. The second water inlet 1220 may be disposed on the side wall of the outer casing 1000 along the first direction X. Both the first water inlet 1210 and the second water inlet 1220 are connected to the filter assembly 2000, and the water outlet 1300 is connected to the water pump assembly 3000. The outer casing 1000 is also provided with a traveling mechanism 5000 at the lower end (negative direction of the Z-axis) along the third direction Z. The traveling mechanism 5000 is disposed on both sides of the outer casing 1000 along the second direction Y. The traveling mechanism 5000 can drive the cleaning equipment to move on the bottom of the pool, the pool wall, etc.

[0063] In this embodiment, the filter assembly 2000 includes a dust bin 2100 and an outer dust box 2200. The dust bin 2100 is detachably disposed within the receiving cavity 1100, or in some embodiments, the outer wall of the receiving cavity 1100 constitutes the dust bin 2100. The dust bin 2100 is detachably connected to the outer shell 1000, for example, by snap-fit ​​or threaded connection. The outer dust box 2200 is disposed within the dust bin 2100, and the outer dust box 2200 and the dust bin 2100 are detachably connected, for example, by overlapping or snap-fit. There is a gap between the outer dust box 2200 and the dust bin 2100, which forms a first water flow channel 4100. The outer dust box 2200 is provided with multiple first filter screens, which can filter the water flowing into the outer dust box 2200, and the filtered water then flows into the first water flow channel 4100. The water pump assembly 3000 is connected to the first water flow channel 4100 and is used to discharge the water in the first water flow channel 4100 from the outlet 1300.

[0064] Please continue to refer to Figure 2 The water pump assembly 3000 of this embodiment includes a water pump 3100 and a water pump cover 3200, with the water pump cover 3200 located on the outer periphery of the water pump 3100. The water pump cover 3200 may be generally cylindrical, for example, and at least a portion of the water pump cover 3200 extends into the outer dust box 2200. A first drainage channel 4200 is formed inside the water pump cover 3200. The first drainage channel 4200 connects the first water flow channel 4100 and the water outlet 1300. When the water pump 3100 is working, it can create a negative pressure in the receiving cavity 1100, thereby drawing external water from the first water inlet 1210 into the machine, filtering it through the filter assembly, and then drawing the water in the first water flow channel 4100 into the first drainage channel 4200.

[0065] In this embodiment, the outer dust box 2200 is generally cylindrical in shape. The outer dust box 2200 includes a bottom wall and at least four sequentially connected side walls, which surround the water pump cover 3200. The water pump cover 3200 is inserted into the outer dust box 2200, allowing water in the first water flow channel 4100 to directly flow into the first drainage channel 4200, eliminating the need for an intermediate water flow channel and thus improving the water flow rate and the filtration efficiency of the cleaning equipment. Specifically, the bottom of the water pump cover 3200 in this embodiment has a water inlet (which can also be considered the water inlet of the water pump assembly 3000). Water filtered by the filter assembly 2000 flows from the first water flow channel 4100 through the water inlet into the water pump cover 3200, and then exits from the water outlet 1300.

[0066] The cleaning equipment in this embodiment can clean the bottom, walls, surface, and waterline of a swimming pool.

[0067] When cleaning the pool bottom, the cleaning equipment can travel along the pool bottom via the traveling mechanism 5000. Under the action of the water pump assembly 3000, water in the pool can enter the filter assembly 2000 through the first water inlet 1210. When cleaning the pool walls and waterline, the cleaning equipment can travel along the pool wall via the traveling mechanism 5000, and at the same time, water in the pool can enter the filter assembly 2000 through the first water inlet 1210. Figure 2 The middle arrow indicates the direction of water flow inside the cleaning equipment. Water entering the filter assembly 2000 from the first inlet 1210 is filtered by the filter assembly 2000 and then flows through the water pump assembly 3000. The water pump assembly 3000 discharges the water from the outlet 1300, thus completing the entire cleaning and filtration process. Note that at this time, the bottom of the filter assembly 2000 is higher than the top of the inlet of the water pump cover 3200.

[0068] When cleaning the water surface, the cleaning equipment can float and move on the water surface driven by a propeller (not shown in the figure). At this time, part of the second water inlet 1220 is below the water surface, and part of the second water inlet 1220 is above the water surface. Please continue to refer to... Figure 2 Water containing debris enters the filter assembly 2000 through the second inlet 1220, and after being filtered by the filter assembly 2000, it enters the first drainage channel 4200 inside the pump housing. Under the action of the pump assembly 3000, the water is discharged from the outlet 1300, thus completing the entire cleaning and filtration process.

[0069] Please continue to refer to Figures 4-7 ,like Figure 4 As shown, when the cleaning equipment moves along the pool wall, the water flow discharged from the outlet 1300 will exert a force on the cleaning equipment. The horizontal component of this force makes the cleaning equipment stick to the pool wall, keeping the cleaning equipment vertical on the pool wall, and generating friction between the drive mechanism 5000 of the cleaning equipment and the pool wall, so that the cleaning equipment moves upward along the pool wall to achieve the wall climbing function.

[0070] However, when the filter assembly 2000 inside the cleaning equipment becomes clogged, the water flow from the filter assembly 2000 to the water pump assembly 3000 decreases, and the drainage volume of the water pump assembly 3000 also decreases. This reduces the force applied to the cleaning equipment, thus posing a risk that the cleaning equipment may fall off the pool wall.

[0071] To improve the above situation, in this embodiment, the filter assembly 2000 is provided with a flow regulating mechanism. When the cleaning equipment moves from the bottom of the pool to the pool wall, the flow regulating mechanism can adjust the fluid flow rate between the filter assembly 2000 and the outlet 1300. For example, when the cleaning equipment moves from the bottom of the pool to the pool wall, the flow regulating mechanism can increase the fluid flow rate between the filter assembly 2000 and the outlet 1300, thereby increasing the drainage capacity of the cleaning equipment. This helps to increase the force applied to the cleaning equipment and reduce the risk of the cleaning equipment falling off the pool wall.

[0072] The flow regulation mechanism of this embodiment includes at least one first flow regulation mechanism 2110, which is disposed on the side wall of the dust bin 2100.

[0073] For example, such as Figure 6 As shown, the first flow regulating mechanism 2110 can be disposed on at least one side of the dust bin 2100 along the second direction Y.

[0074] Please continue to refer to Figures 4-7 In this embodiment, the first flow regulating mechanism 2110 includes at least one first through hole 2111 and a first control plate 2112. The first through hole 2111 is disposed on the side wall of the dust bin 2100 and connects the internal space and the external space of the dust bin 2100. The first control plate 2112 is rotatably disposed on the dust bin 2100. For example, the first control plate 2112 is disposed on the side wall of the dust bin 2100 corresponding to the position of the first through hole 2111. Exemplarily, one or more first through holes 2111 can be provided in this embodiment. The first through hole 2111 can be square, circular or other shapes, and the aperture of the first through hole 2111 can be set as needed. In this embodiment, the first through hole 2111 is preferably rectangular. Multiple first through holes 2111 are provided and are equally spaced on the dust bin 2100. It is understood that multiple first through holes 2111 can also be irregularly arranged on the dust bin 2100. The dust bin 2100 is provided with a second rotating mounting part 2130. The first control plate 2112 is rotatably mounted on the second rotating mounting part 2130. When the first control plate 2112 rotates around the second rotating mounting part 2130, it can open or cover the first through hole 2111.

[0075] like Figure 5 As shown, when the cleaning equipment moves along the bottom of the pool or the surface of the water, the first control plate 2112 is in the first position, which can block the first through hole 2111. At this time, it is impossible to connect with the first water flow channel 4100 through the first through hole 2111, and the external water flow cannot enter the first water flow channel 4100 through the first through hole 2111, thus it is impossible to increase the drainage volume of the cleaning equipment.

[0076] like Figure 4As shown, when the cleaning equipment moves along the pool wall, the first control plate 2112 is in the second position, exposing at least part of the first through hole 2111, so that the internal space of the cleaning equipment is connected to the first water flow channel 4100 through the first through hole 2111. At this time, the water flow in the internal space of the cleaning equipment can enter the first water flow channel 4100 through the first through hole 2111, and then be discharged from the outlet through the first drainage channel 4200. Therefore, increasing the drainage capacity of the cleaning equipment helps to increase the force applied to the cleaning equipment and reduce the risk of the cleaning equipment falling off the pool wall.

[0077] Understandably, when the cleaning equipment moves from the bottom of the pool to the pool wall, the first control plate 2112 rotates to move from the first position to the second position, thereby gradually exposing the first through hole 2111, increasing the fluid flow rate from the dust bin to the outlet, and thus gradually increasing the pressure of the cleaning equipment on the pool wall. Figure 4 As shown, when the cleaning equipment moves along the pool wall, the first control panel 2112 remains stationary in the second position, and the drainage capacity of the cleaning equipment reaches its maximum value.

[0078] In some embodiments, the first control plate 2112 of this embodiment is disposed on the side of the first through hole 2111 facing away from the dust bin 2100, and a baffle 2120 is also provided on the side of the first through hole 2111 facing the dust bin 2100. The baffle 2120 is detachably connected to the dust bin 2100. For example, the baffle 2120 can be detachably connected to the dust bin 2100 by means of snap-fit, plug-in, etc., thereby facilitating installation and disassembly during use. The baffle 2120 is used to block the communication between the first through hole and the internal and external spaces of the dust bin 2100. When the baffle 2120 is in the installed position, the first through hole is not connected to the internal or external spaces of the dust bin 2100. When the baffle 2120 is removed, the first through hole is connected to the internal and external spaces of the dust bin.

[0079] Understandably, by setting up the baffle 2120, the first through hole 2111 can be blocked, thereby disabling the first flow regulating mechanism 2110. This prevents water from flowing directly into the water pump assembly 3000 from the cleaning equipment, allowing only the water filtered by the filter assembly 2000 to flow into the water pump assembly 3000, thus ensuring the service life of the water pump assembly. When the cleaning equipment is cleaning the pool wall, the user can selectively remove the baffle 2120 as needed, allowing the first flow regulating mechanism 2110 to function normally, increasing the drainage capacity of the cleaning equipment, increasing the force applied to the cleaning equipment, and reducing the risk of the cleaning equipment falling off the pool wall.

[0080] In some embodiments, the first control board 2112 of this embodiment includes a first body 21121 and a first counterweight 21122; wherein, the first end of the first body 21121 is hinged to the side wall of the dust bin 2100, and the first counterweight 21122 is disposed at the second end of the first body 21121. Exemplarily, the first counterweight 21122 may be made of a heavy material (density greater than water density) such as metal or stone, and a corresponding second mounting cavity may be provided inside the first body 21121, within which the first counterweight 21122 may be disposed.

[0081] When the cleaning equipment moves from the bottom of the pool to the wall of the pool, the first counterweight 21122 drives the first control plate 2112 to rotate relative to the dust bin under its own weight, thereby exposing at least part of the first through hole 2111.

[0082] When the cleaning equipment is located at the bottom of the pool or in a near-horizontal state, the first control panel 2112 can block all the first through holes 2111 under the weight of the first counterweight 21122.

[0083] In some embodiments, the first counterweight 21122 can also be a buoyancy block made of a material with a density less than that of water. In this case, the second rotating mounting part 2130 is disposed below the first through hole 2111. In one position, the first control plate 2112 blocks the first through hole 2111 under the action of the buoyancy block, preventing liquid outside the dust chamber from entering the dust chamber through the first through hole 2111. When the cleaning equipment moves from the bottom of the pool to the pool wall, the buoyancy block rotates the first control plate 2112 relative to the dust chamber under its own buoyancy, thereby exposing at least part of the first through hole 2111. When the cleaning equipment moves on the pool wall, the first control plate 2112 is in a second position relative to the dust chamber. At this time, at least part of the first through hole 2111 is retained, thereby increasing the water flow from the filter assembly to the outlet, increasing the pressure of the cleaning equipment on the pool wall, and effectively preventing the cleaning equipment from falling off the pool wall.

[0084] Please continue to refer to Figure 8 and Figure 9In this embodiment, the flow regulating mechanism further includes at least one second flow regulating mechanism 2210, which is disposed on the side wall of the outer dust box 2200. Exemplarily, the second flow regulating mechanism 2210 in this embodiment includes at least one second through hole 2211 and a second control plate 2212. The second through hole 2211 is disposed on the side wall of the outer dust box 2200 and communicates the inner and outer spaces of the outer dust box. The size of the second through hole 2211 is greater than or equal to the size of the filter holes of the filter screen on the outer dust box 2200. The second control plate 2212 is rotatably disposed on the outer dust box 2200, for example, it can be disposed on the inner or outer side of the side wall of the outer dust box 2200 corresponding to the position of the second through hole 2211. Exemplarily, this embodiment may have one or more second through holes 2211, which may be square, circular, or other shapes, and the diameter of the second through hole 2211 can be set as needed. In this embodiment, the second through hole 2211 is preferably circular, and multiple second through holes 2211 are provided, spaced apart on the outer dust box 2200. The outer dust box 2200 is provided with a first rotating mounting part 2220, and the second control plate 2212 is rotatably sleeved on the first rotating mounting part 2220. When the second control plate 2212 rotates around the first rotating mounting part 2220, it can open or close the second through hole 2211.

[0085] like Figure 11 As shown, when the cleaning equipment moves along the bottom of the pool or the surface of the water, the second control panel 2212 is in the first position, and the second control panel 2212 can completely cover the second through hole 2211. At this time, the second through hole 2211 is not connected to the first water flow channel 4100, and the water flow in the outer dust box 2200 cannot enter the first water flow channel 4100 through the second through hole 2211, thus it is impossible to increase the water inflow and drainage of the water pump assembly 3000.

[0086] When the cleaning equipment moves along the pool wall, the second control panel 2212 is in the second position. The second control panel 2212 can expose at least part of the second through hole 2211 so that the internal space of the outer dust box 2200 can be connected to the first water flow channel 4100 through the second through hole 2211. That is, at this time, the second through hole 2211 is connected to the first water flow channel 4100, and the water flow in the outer dust box 2200 can enter the first water flow channel 4100 through the second through hole 2211, thereby increasing the amount of water flowing from the filter assembly to the water pump assembly 3000. This increases the amount of water discharged by the machine through the outlet 1300, which helps to increase the pressure of the cleaning equipment on the pool wall and reduces the risk of the cleaning equipment falling off the pool wall.

[0087] Understandably, when the cleaning equipment moves from the bottom of the pool to the pool wall, the second control plate 2212 rotates to move from the first position to the second position, thereby gradually exposing the second through hole 2211, which gradually increases the drainage volume of the cleaning equipment.

[0088] In some embodiments, the second control board 2212 of this embodiment includes a second main body 22121 and a second counterweight 22122; wherein, the first end of the second main body 22121 is hinged to the outer dust box 2200, and the second counterweight 22122 is disposed at the second end of the second main body 22121. Exemplarily, the second counterweight 22122 can be made of a heavy material (a material with a density greater than that of water), such as metal or stone, and the second main body 22121 can have a corresponding first mounting cavity, within which the second counterweight 22122 can be disposed.

[0089] When the cleaning equipment moves from the bottom of the pool to the pool wall, the second counterweight 22122 drives the second control plate 2212 to rotate under its own weight, thereby exposing at least part of the second through hole 2211.

[0090] When the cleaning equipment is located at the bottom of the pool or in a near-horizontal state (e.g., when walking on the water surface), the second counterweight 22122 keeps the second control plate 2212 in a vertical state under its own weight (even if the second control plate 2212 is in the first position), thereby blocking the second through hole 2211.

[0091] In some embodiments, the second counterweight 22122 can also be a buoyancy block made of a material with a density less than that of water. In this case, the first rotating mounting part 2220 is disposed below the second through hole 2211. In one position, the second control plate 2212 blocks the second through hole 2211 under the action of the buoyancy block, so that the liquid in the outer dust box cannot enter the first water flow channel 4100 through the second through hole 2211. When the cleaning equipment turns from the bottom of the pool to the pool wall, the buoyancy block rotates the second control plate 2212 relative to the outer dust box under its own buoyancy, thereby exposing at least part of the second through hole 2211. At this time, the liquid inside the outer dust box can enter the first water flow channel 4100 through the second through hole, thereby increasing the water flow rate from the filter assembly to the outlet. When the cleaning equipment moves along the pool wall, the second control panel 2212 is in the second position relative to the outer dust box. At this time, at least part of the second through hole 2211 is exposed, thereby increasing the water flow from the filter assembly to the outlet, increasing the pressure of the cleaning equipment on the pool wall, and effectively preventing the cleaning equipment from falling off the pool wall.

[0092] In some embodiments, such as Figure 8As shown, the second flow regulating mechanism 2210 can be provided on at least one side of the outer dust box 2200 along the second direction Y. For example, the second flow regulating mechanism 2210 can be provided on both sides of the outer dust box 2200 along the second direction Y.

[0093] Please continue to refer to Figure 3 and Figure 8 In this embodiment, the filter assembly 2000 further includes an inner dust box 2300, which is located inside the outer dust box 2200 and is detachably connected to the outer dust box 2200. For example, the inner dust box 2300 can be detachably connected to the bottom wall of the outer dust box 2200 by means of screws, snap-fit, or other methods.

[0094] The water pump cover 3200 is located inside the inner dust box 2300, forming a second water flow channel 4300 between the inner dust box 2300 and the water pump cover 3200. The second water flow channel 4300 is interconnected with the first drainage channel 4200 and the first water flow channel 4100. For example, the inner dust box 2300 may be provided with multiple second filters. Part of the water flow in the outer dust box 2200 can be filtered again by the second filters before flowing into the second water flow channel 4300, thereby further improving the filtration efficiency of the cleaning equipment. In some embodiments, the inner dust box 2300 also has a non-filtering surface, which is located near the first water inlet 1210.

[0095] In this embodiment, the inner dust box 2300 is a rotating cylindrical filter surface, generally elliptical in shape. The inner dust box 2300 is detachably or non-detachably fixedly connected to the bottom wall of the outer dust box 2200. The outer dust box 2200 is arranged around the inner dust box 2300, and the inner dust box 2300 is arranged around the water pump cover 3200.

[0096] Please continue to refer to Figure 3 ,like Figure 3 As shown by the dashed arrow, when the cleaning equipment in this embodiment is working, water can enter the outer dust box 2200 from either the first inlet 1210 or the second inlet 1220. Part of the water in the outer dust box 2200 is filtered by the first filter and then enters the first water flow channel 4100 between the outer dust box 2200 and the dust chamber 2100. Under the action of the water pump 3100, the water in the first water flow channel 4100 enters the first drainage channel 4200 and is finally discharged from the outlet 1300 on the end cover.

[0097] Another portion of the water in the outer dust box 2200 is filtered by the second filter and enters the second water flow channel 4300 between the inner dust box 2300 and the water pump cover 3200. Under the action of the water pump 3100, the water in the second water flow channel 4300 enters the first drainage channel 4200 and is finally discharged from the outlet 1300 on the end cover.

[0098] As can be seen from the above description, the cleaning component of this embodiment can simultaneously filter water flow using the outer dust box 2200 and the inner dust box 2300, thereby improving the filtration efficiency of the cleaning equipment.

[0099] In this embodiment, the mesh count of the first filter screen and the mesh count of the second filter screen may be the same or different. It is understood that the higher the mesh count of the filter screen, the higher its filtration accuracy. In this embodiment, for example, the mesh count of the second filter screen can be greater than that of the first filter screen, thereby giving the second filter screen higher filtration accuracy.

[0100] Please continue to refer to Figure 8 In this embodiment, the surface of the inner dust box 2300 opposite to the water inlet 1200 is a non-filtering surface 2310. The non-filtering surface 2310 allows the liquid entering the outer dust box from the first water inlet 1210 to bypass the non-filtering surface and flow to the first filter surface of the outer dust box or to the second filter surface of the inner dust box, thereby preventing impurities such as leaves from accumulating on the non-filtering surface and causing blockage at the first water inlet.

[0101] like Figure 12 As shown, Figure 12 Only the structures of the outer and inner dust boxes are illustrated, ignoring other unrelated components. In this embodiment, a non-filtering surface 2310 is provided in the inner dust box near the first water inlet 1210. The flow regulation mechanism in this embodiment also includes a third flow regulation mechanism 2320 disposed on the non-filtering surface 2310. The third flow regulation mechanism 2320 can adopt a structure similar to the second flow regulation mechanism 2210 and the first flow regulation mechanism 2110 described above. Exemplarily, the third flow regulation mechanism 2320 includes at least one third through hole and a third control plate. The third control plate is rotatably disposed on the non-filtering surface 2310 of the inner dust box 2300. By rotating the third control plate, the third through hole can be opened or closed.

[0102] When the cleaning equipment moves along the bottom of the pool or the surface of the water, the third control panel can cover the third through hole, thereby preventing water in the outer dust box 2200 from flowing into the second water flow channel 4300 through the third through hole.

[0103] As the cleaning equipment moves along the pool wall, the third control panel rotates to expose at least part of the third through-hole, connecting the outer dust box 2200 to the second water flow channel 4300. At this time, water in the outer dust box 2200 can flow into the second water flow channel 4300 through the third through-hole, thereby increasing the amount of water flowing into the water pump assembly 3000 through the second water flow channel 4300, and consequently increasing the drainage capacity of the water pump assembly 3000. This helps to increase the force applied to the cleaning equipment and reduces the risk of the cleaning equipment falling off the pool wall.

[0104] In some embodiments, the third control board of this embodiment includes a third body and a third counterweight. The first end of the third body is hinged to the non-filter surface of the inner dust box 2300, and the third counterweight is disposed at the second end of the third body. Exemplarily, the third counterweight can be made of a heavy material (density greater than that of water), such as metal or stone. A corresponding third mounting cavity can be provided within the third body, and the third counterweight can be disposed within this third mounting cavity. Similarly, the third counterweight is also composed of a buoyancy block, and its structure is similar to the structure of the first or second flow regulating mechanism using a buoyancy block; further details are omitted here.

[0105] When the cleaning equipment moves from the bottom of the pool to the pool wall, the third counterweight drives the third control plate to rotate under its own weight, thereby exposing at least part of the third through hole.

[0106] When the cleaning equipment is located at the bottom of the pool or in a near-horizontal state, the third counterweight keeps the third control plate vertical under its own weight, thereby blocking the third through hole.

[0107] In this embodiment, the third flow regulating mechanism 2320 can be disposed on at least one side of the inner dust box 2300 along the second direction Y. For example, the third flow regulating mechanism 2320 can be disposed on both sides of the inner dust box 2300 along the second direction Y. The third flow regulating mechanism 2320 can also be disposed on other side walls of the inner dust box 2300 as needed.

[0108] In some embodiments, the cleaning device is provided with at least one of a first flow regulating structure, a second flow regulating mechanism, and a third flow regulating mechanism.

[0109] In other embodiments, such as Figure 10 As shown, the second flow regulating mechanism 2210 can be disposed on at least one side of the outer dust box 2200 along the first direction X. For example, the second flow regulating mechanism 2210 can be disposed on the inner side of the front wall of the outer dust box 2200 (along the first direction X, with the positive X-axis direction being front and the negative X-axis direction being rear), i.e. Figure 10 As shown, the inner surface of the outer dust box 2200 is located on the side near the first water inlet 1220.

[0110] In this embodiment, the second main body 22121 may also be provided with a filter surface. The filter mesh number of the filter surface is equal to the filter mesh number of the outer dust box 2200 (i.e., the mesh number of the first filter screen). When the second control plate 2212 blocks the second through hole 2211, the water flow can still pass through the filter surface on the second main body 22121, thereby ensuring that the second flow regulating mechanism 2210 and the other positions on the outer dust box 2200 maintain the filtration capacity.

[0111] The following is a detailed description Figure 10The specific structure of the second flow regulating mechanism 2210.

[0112] Please see Figure 13-20 , Figure 13 for Figure 10 A partial cross-sectional view of part A. The second flow regulating mechanism 2210 includes at least one second through hole 2211 and a second control plate 2212. The second through hole 2211 is disposed on the front side wall of the outer dust box 2200 and is used to connect the inner and outer spaces of the outer dust box 2200. When the second control plate 2212 is in the first position (see attached diagram), Figure 13 , 15 (In the first position), the second control panel 2212 can block the second through hole 2211. At this time, the liquid in the inner dust box cannot connect with the first water flow channel 4100 through the second through hole 2211, and thus cannot increase the drainage volume of the cleaning equipment.

[0113] When the cleaning equipment moves along the pool wall, the second control panel 2212 is in the second position (e.g., Figure 14 , 16 (As shown in the second position), the second control panel 2212 can expose at least part of the second through hole 2211, allowing the liquid inside the outer dust box to connect with the first water flow channel 4100 through the second through hole 2211. This increases the drainage capacity of the cleaning equipment, which is beneficial for increasing the force applied to the cleaning equipment and reducing the risk of the cleaning equipment falling off the pool wall.

[0114] When the cleaning equipment moves from the bottom of the pool to the pool wall, the second control board 2212 changes from the first position to the second position. At this time, the fluid flow from the filter component to the suction component gradually increases until the cleaning equipment completely climbs up the pool wall. When the second control board 2212 is in the second position, the flow rate remains basically the same while the power of the suction component remains unchanged.

[0115] The aforementioned first position can be the position of the second control panel when the cleaning equipment is cleaning the bottom of the pool and the water surface.

[0116] The outer dust box 2200 is perforated on all sides, with the first filter surface located at the perforated area. The second through hole 2211 can be located at the perforated area of ​​the outer dust box 2200 or at other locations on the outer dust box 2200. Alternatively, the second through hole 2211 can be located on the first filter surface. When the second through hole 2211 is located on the first filter surface, the structure of the outer dust box 2200 limits the second through hole 2211, increasing the stability of the second control plate 2212 in closing or opening the second through hole 2211.

[0117] In some embodiments, the second control plate 2212 can be driven by a driving component (not shown in the figure), which is connected to the second control plate 2212 to achieve the closing and opening of the second through hole 2211. The driving component may include a drive motor (not shown in the figure), which is connected to the second control plate 2212 to control its movement. Alternatively, the second control plate 2212 may have related structures, and the second control plate 2212 and related structures can drive itself to achieve the closing and opening of the second through hole 2211. In other embodiments, the second control plate 2212 can also close and open the second through hole 2211 in other ways, which are not limited here. The second control plate 2212 may be a cover plate, a flip plate, etc.

[0118] The aforementioned second control plate 2212 can be installed on the outer dust box 2200. The second control plate 2212 can be installed on the outer dust box 2200 by means of pivoting, telescopicing, hinge, etc., and is used to cover or open the second through hole 2211, etc.; for example, the second control plate 2212 can be installed on the front side wall of the outer dust box through the first rotating mounting part 2220.

[0119] Please continue reading. Figure 13-20 In some embodiments, the second control plate 2212 is pivotally connected to the outer dust box 2200. When the second control plate 2212 is pivotally connected to the outer dust box 2200, it makes it easier for the second control plate 2212 to close and open the second through hole 2211.

[0120] The second control board 2212 in this embodiment includes a second main body 22121 and a second counterweight 22122; wherein, the first end of the second main body 22121 is pivotally connected to the outer dust box 2200 or rotatably connected through the first rotating mounting part, and the second counterweight 22122 is disposed at the second end of the second main body 22121, and the second counterweight 22122 assists the second control board 2212 in covering or opening the second through hole 2211.

[0121] In the first position, the pivot point of the second control plate 2212 rotating around the outer dust box 2200 is located on the line of action of the resultant force of gravity and buoyancy on the second control plate 2212 and the second counterweight 22122. That is to say, the rotational torque of the second control plate 2212 around the outer dust box 2200 is zero. Therefore, the second control plate 2212 will not pivot and will always be in a vertical state, so that the second through hole 2211 can be well covered.

[0122] In the second position, since the cleaning equipment is located on the pool wall, its filter components are either tilted or vertical (e.g., ...). Figure 4(In its current state), the pivot point of the second control plate 2212 rotating around the outer dust box 2200 deviates from the line of action of the resultant force of gravity and buoyancy acting on the second control plate 2212 and the second counterweight 22122. In other words, the rotational torque of the second control plate 2212 around the outer dust box 2200 is no longer zero. Therefore, the second control plate 2212 has a rotational torque around the outer dust box 2200, forcing it to rotate and open the second through hole 2211. The second counterweight 22122 can be a component of different densities, as long as it assists the movement of the second control plate 2212; its specific structure is not limited.

[0123] By setting the second counterweight 22122 and its position on the second main body 22121, the second control plate 2212 can be closed to or opened more quickly, thereby increasing the water output of the filter device and the water intake of the pump suction component, thus improving the performance of the cleaning equipment in climbing walls or slopes. Furthermore, the second control plate 2212 can change autonomously between the first and second positions, which can reduce the use of drive components and save costs.

[0124] Specifically, the second main body 22121 includes a first side end 2a and a second side end 2b disposed opposite to each other. When the second control plate 2212 is in the first position, the first side end 2a is located at the uppermost end of the second control plate 2212, and the second side end 2b is located at the lowermost end of the second control plate 2212. Both the first side end 2a and the second side end 2b can be pivotally connected to the outer dust box 2200. However, due to the different positions of the first side end 2a and the second side end 2b, the overall force on the second control plate 2212 will be different when they are pivotally connected to the outer dust box 2200. In order to achieve the purpose of closing the second through hole 2211 in the first position and opening the second through hole 2211 in the second position, whether the first side end 2a or the second side end 2b is pivotally connected to the outer dust box 2200, the setting of the second counterweight 22122 must be adjusted to assist the second control plate 2212 in applying force. Based on this, the following section provides a detailed description and analysis of the specific results when the first side end 2a or the second side end 2b is pivotally connected to the outer dust box 2200:

[0125] Example 1:

[0126] In this first embodiment, the first side end 2a is pivotally connected to the outer dust box 2200 (or the first rotating mounting part 2220 is considered to be disposed on the first side end 2a), and the second side end 2b pivots around the first side end 2a to move away from or against the outer dust box 2200, so as to open or close the second through hole 2211. At this time, the entire filter assembly is located underwater, and the weight of the second counterweight 22122 is set to be greater than the buoyancy.

[0127] Specifically, the first side end 2a is pivotally connected to the outer dust box 2200, and the second counterweight 22122 is located away from the pivotal connection between the first side end 2a and the outer dust box 2200. Because the weight of the second counterweight 22122 is greater than the buoyancy, when the cleaning device changes from horizontal to tilted, the second side end 2b can pivot around the first side end 2a to move away from the outer dust box 2200, causing the second control plate 2212 to open the second through hole 2211. Alternatively, when the cleaning device changes from tilted to horizontal, the second side end 2b can pivot around the first side end 2a to abut against the outer dust box 2200, causing the second control plate 2212 to close to the second through hole 2211. The weight of the second counterweight 22122 is much greater than the buoyancy of the second control plate 2212 in water. When the cleaning equipment is located at the bottom of the pool or in a horizontal position, the second control plate 2212, relying on the gravity of the second counterweight 22122, helps to form a certain preload force in the direction of gravity, which enables the second control plate 2212 to adhere to the outer dust box 2200. When the cleaning equipment moves from the bottom of the pool to the pool wall, the second control plate 2212, relying on its own weight and the gravity of the second counterweight 22122, causes the second side end 2b to pivot around the first side end 2a and move away from the outer dust box 2200.

[0128] Thus, by pivoting the first side end 2a to the outer dust box 2200, and pivoting the second side end 2b around the first side end 2a to move away from or against the outer dust box 2200, the gravity of the second counterweight 22122 is greater than the buoyancy, which not only increases the speed at which the second control board 2212 closes or opens the second through hole 2211, but also makes it easier for the second control board 2212 to change autonomously between the first position and the second position, reducing the use of drive components and saving costs.

[0129] Optionally, in this embodiment, the density of the second counterweight 22122 is greater than the density of water (1 g / cm3). The density of the second counterweight 22122 can be 1.1 g / cm3, 2 g / cm3, 3 g / cm3, 3.4 g / cm3, 4.3 g / cm3, etc., and is not limited here. When the second control plate 2212 is in the first position, the second control plate 2212 extends along the direction of gravity due to the combined gravitational force formed by the second counterweight 22122, that is, the second control plate 2212 remains vertical, and at this time the second control plate 2212 can cover the second through hole 2211. In addition, when the second control plate is in the second position, the second control plate 2212 can open the second through hole 2211 by the combined force of its own weight and the weight of the second counterweight 22122.

[0130] Therefore, by limiting the density of the second counterweight 22122, it is convenient to adjust the second control plate 2212 to quickly close or open the second through hole 2211. The aforementioned second counterweight 22122 can be a metal block, alloy block, stone, etc., and is not limited here.

[0131] In some specific application scenarios, the second counterweight 22122 protrudes from the inner side 25 of the second control plate 2212 facing the inner dust box. When the second control plate is in the first position, the line connecting the center of gravity of the second counterweight 22122 and the pivot center of the second control plate 2212 forms an acute angle with the direction of gravity. The second counterweight 22122 is detachably or fixedly connected to the second main body of the second control plate 2212. The detachable method can be snap-fit, plug-in, or bolted; for example, the second counterweight 22122 can be detachably or non-detachably fixed in the first mounting cavity of the second main body. The line connecting the center of gravity of the second counterweight 22122 and the pivot center of the second control plate 2212 forms an acute angle with the direction of gravity. That is, the center of gravity of the second counterweight 22122 is set higher than the inner side surface 25 of the second control plate 2212, so as to increase the preload of the second control plate 2212 in the first position, thereby improving the tightness of the second control plate 2212 covering the second through hole 2211; at the same time, it is easier for the second control plate 2212 to pivot away from the second through hole 2211, thereby increasing the speed at which the second control plate 2212 opens the second through hole 2211.

[0132] In some embodiments, the second control plate 2212 is provided with a connecting portion 21. The connecting portion 21 provides a first mounting cavity for the second counterweight 22122. The second counterweight 22122 can be disposed in the connecting portion 21 by snap-fit, plug-in, or bolt fixing.

[0133] Example 2:

[0134] Please see Figure 15 , Figure 16 , Figure 19 The second side end 2b is pivotally connected to the outer dust box 2200. The first side end 2a pivots around the second side end 2b to move away from or against the outer dust box 2200, so as to open or close the second through hole 2211. At this time, the entire filter assembly is underwater, that is, the entire filter assembly is located below the water surface, and the buoyancy of the second counterweight 22122 is set to be greater than the gravity.

[0135] Specifically, the second side end 2b is pivotally connected to the outer dust box 2200, and the second counterweight 22122 is away from the pivotal connection between the second side end 2b and the outer dust box 2200. The first side end 2a can pivot around the second side end 2b to move away from the outer dust box 2200, causing the second control plate 2212 to open the second through hole 2211. Alternatively, the first side end 2a can pivot around the second side end 2b to abut against the outer dust box 2200. Because the buoyancy of the second counterweight 22122 is greater than its weight, the second control plate 2212 closes to the second through hole 2211. The buoyancy of the second counterweight 22122 is much greater than the weight of the second control plate 2212 in water. When the second control plate is in the first position, the second control plate 2212 extends along the buoyancy direction due to the buoyancy of the second counterweight 22122, at which time the second control plate 2212 can close to the second through hole 2211. When the second control board is in the second position, the second control board 2212 changes its position due to its own gravity, causing the first side end 2a to pivot around the second side end 2b to move away from the outer dust box 2200.

[0136] Thus, by pivoting the second side end 2b to the outer dust box 2200, the first side end 2a pivots around the second side end 2b to move away from or against the outer dust box 2200. The buoyancy of the second counterweight 22122 is greater than the gravity, which not only increases the speed at which the second control board 2212 closes or opens the second through hole 2211, but also makes it easier for the second control board 2212 to change autonomously between the first position and the second position, reducing the use of drive components and saving costs.

[0137] Optionally, in this embodiment, the density of the second counterweight 22122 is less than 1 g / cm³. The density of the second counterweight 22122 can be 0.9 g / cm³, 0.8 g / cm³, 0.64 g / cm³, 0.54 g / cm³, 0.1 g / cm³, etc., and is not limited here. That is, the density of the second counterweight 22122 needs to be less than the density of water. When the second control plate is in the first position, the second control plate 2212 is in a vertical state due to the buoyancy of the second counterweight 22122, and the second control plate 2212 covers the second through hole 2211. Additionally, when the second control plate is in the second position, the second control plate 2212 can open the second through hole 2211 by relying on the change in its own weight.

[0138] Therefore, by limiting the density of the second counterweight 22122, it is convenient to adjust the second control plate 2212 to quickly cover the second through hole 2211. The second counterweight 22122 can be foam, plastic, or filled with other air bladders, etc., and is not limited here. In this embodiment, the second counterweight 22122 is foam.

[0139] More specifically, in this second embodiment, the second control panel further includes a movable member 32. The second control panel 2212 also includes a receiving channel 22. The receiving channel 22 is disposed between the first side end 2a and the second side end 2b. The centerline of the receiving channel 22 intersects the plane containing the first side end 2a or the second side end 2b. The movable member 32 is housed within the receiving channel 22 and can move along the receiving channel 22.

[0140] During the process of the second control plate changing from the first position to the second position, or from the second position to the first position, the movable component 32 is accommodated within the accommodating channel 22 and can move along the accommodating channel 22. The positional change of the movable component 32 alters the overall center of gravity of the second control plate 2212, allowing it to quickly close or shut off the second through hole 2211, thus improving the cleaning equipment's wall-climbing, slope-climbing, or operational performance. The movable component 32 can be a rolling element (not shown in the figure). The rolling element's movement within the accommodating channel 22 reduces friction between it and the channel, thereby enabling a faster change in the center of gravity of the second control plate 2212. The rolling element can be a ball bearing. The density of the ball bearing can be greater than the density of water (1 g / cm³). The size of the ball bearing can be determined based on actual conditions and is not limited here.

[0141] The aforementioned receiving channel 22 is disposed between the first side end 2a and the second side end 2b, with its centerline intersecting the plane containing the first side end 2a, meaning the receiving channel 22 is positioned close to the first side end 2a. Alternatively, the receiving channel 22 is disposed between the first side end 2a and the second side end 2b, with its centerline intersecting the plane containing the second side end 2b, meaning the receiving channel 22 is positioned close to the second side end 2b. The receiving channel 22 can be positioned at any angle at either the first side end 2a or the second side end 2b.

[0142] In some embodiments, the centerline of the receiving channel 22 intersects perpendicularly with the plane containing the first side end 2a or the second side end 2b. Alternatively, the centerline of the receiving channel 22 intersects perpendicularly with the plane containing the first side end 2a. When the moving member 32 moves along the receiving channel 22, its center of gravity can change from the first side end 2a to the second side end 2b, giving the center of gravity of the second control plate 2212 a certain regularity, which is simple and easy to implement.

[0143] In some embodiments, the second control plate 2212 includes an inner surface 25 facing the inner dust box. A receiving channel 22 extends from the second side end 2b toward the first side end 2a in a direction close to the inner surface 25. The receiving channel 22 extends from the second side end 2b toward the inner surface 25 and simultaneously toward the first side end 2a. That is, the receiving channel 22 is inclined. When the second control plate is in the second position, the moving member 32 moves within the inclined receiving channel 22 from the second side end 2b to the first side end 2a due to gravity. At this time, the center of gravity of the second control plate 2212 moves forward, causing the gravity of the center of gravity of the second control plate 2212 to be greater than the buoyancy of the second control plate 2212, thereby opening the second through hole 2211.

[0144] By changing the tilt direction of the receiving channel 22, the moving part 32 can be moved, and the center of gravity of the second control plate 2212 can be changed quickly, thereby enabling the second control plate 2212 to quickly open or close the second through hole 2211.

[0145] Regardless of whether it is Embodiment 1 or Embodiment 2, or any other specific embodiment, the second control board 2212 can be directly pivotally connected to the side wall of the outer dust box 2200. However, for the sake of installation stability and firmness, the second control board 2212 can also be indirectly pivotally connected to the side wall of the outer dust box 2200 through other mounting components, such as mounting bracket 4.

[0146] In some embodiments, please refer to Figures 13 to 16 The mounting bracket 4 is disposed on the side wall of the outer dust box 2200. The mounting bracket 4 covers the second through hole 2211. The portion of the mounting bracket 4 covering the second through hole 2211 is provided with several grille holes 41. The grille holes 41 communicate with the second through hole 2211. The second control plate 2212 is movably mounted on the mounting bracket 4.

[0147] Specifically, the mounting bracket 4 is detachable or fixed to the side wall of the outer dust box 2200. During installation of the mounting bracket 4 onto the side wall of the outer dust box 2200, the mounting bracket 4 covers the second through hole 2211. The portion of the mounting bracket 4 covering the second through hole 2211 is provided with several grid holes 41. These grid holes 41 are connected to the second through hole 2211. When the second control plate is in the second position, at least a portion of the water in the outer dust box can flow out sequentially through the second through hole 2211 and the grid holes 41. By providing grid holes 41 on the mounting bracket 4, large impurities (such as leaves) are prevented from entering the pump suction assembly and damaging the impeller in the pump suction assembly after the second control plate 2212 is opened. The size and shape of the aforementioned grid holes 41 are not limited, as long as they meet the actual usage requirements. In this embodiment, the grid holes 41 are square in shape.

[0148] Furthermore, the mounting bracket 4 can be detachably installed onto the side wall of the outer dust box 2200. The detachability can be achieved through snap-fit, bolt fixing, or insertion. In this embodiment, the mounting bracket 4 has several mounting portions 44 on its outer periphery. Each mounting portion 44 has mounting holes (not shown in the figure). The fastener passes through the mounting holes and is fixed to the side wall of the outer dust box 2200. Additionally, the mounting bracket 4 has several mounting clips 45 on its outer periphery. The mounting clips 45 are inserted into and snapped onto the side wall of the second through hole 2211. Through the cooperation of the mounting portions 44 and the mounting clips 45, the stability of the mounting bracket 4 installed onto the side wall of the outer dust box 2200 is improved, thereby enhancing the stability of the filter assembly. The location and number of the mounting bracket 4 and the mounting clips 45 can be determined according to actual conditions and are not limited here.

[0149] Additionally, when the external dust box 2200 is equipped with a mounting bracket 4, the second control board 2212 can be movably mounted on the mounting bracket 4. The movement can be achieved by rotation. The second control board 2212 is rotatably connected to the mounting bracket 4.

[0150] In some more specific embodiments, the mounting bracket 4 has a recessed receiving cavity 42 on one side facing the inner dust box. The side wall of the receiving cavity 42 has a pivot mounting groove 43. The second control plate 2212 is movably accommodated within the receiving cavity 42. The second control plate 2212 has a protruding pivot portion 23. A stop limiting protrusion is provided below the pivot portion 23. The pivot portion 23 is pivotally mounted within the pivot mounting groove 43. The stop limiting protrusion rotates with the second control plate 2212 until it stops against the side wall.

[0151] A recessed cavity 42 is recessed on one side of the mounting bracket 4 facing the inner dust box, and the cavity 42 can accommodate the second control plate 2212. The cavity 42 is connected to the pivot mounting groove 43. A pivot part 23 is detachably or non-detachably mounted on one end of the second control plate 2212. When the second control plate 2212 is movably mounted in the cavity 42, the pivot part 23 is pivotally mounted in the pivot mounting groove 43, realizing the rotation of the second control plate 2212. A stop limiting protrusion is provided below the pivot part 23. The pivot part 23 and the stop limiting protrusion are detachably or non-detachably fixedly connected. The stop limiting protrusion can play a stop limiting role. When the pivot part 23 pivots, the stop limiting protrusion also rotates with the pivot part 23. When the second control plate 2212 rotates to a certain angle, the stop limit protrusion stops on the side wall of the receiving cavity 42, thereby stopping the second control plate 2212 from rotating and limiting the rotation angle of the second control plate 2212.

[0152] The aforementioned receiving cavity 42, pivot mounting groove 43, pivot part 23, and stop limiting protrusion cooperate with each other to limit the rotation angle of the second control plate 2212, thereby preventing the second control plate 2212 from rotating too much and causing it to be adsorbed onto the side wall of the outer dust box 2200, which would affect the closing of the second control plate 2212, etc.

[0153] When the second control plate is in the second position, the second control plate 2212, through the aforementioned stop and limiting protrusions and other related structures, can limit the angle between the second control plate 2212 and the outer dust box 2200. Specifically, the angle between the second control plate 2212 and the outer dust box 2200 is greater than or equal to 30° and less than or equal to 100°. The angle between the second control plate 2212 and the outer dust box 2200 can be 30°, 43°, 54°, 65°, 76°, 87°, 90°, 98°, 100°, etc., and is not limited here. By limiting the angle range between the second control plate 2212 and the outer dust box 2200, it is not only convenient for at least part of the water in the inner dust box to flow out through the second through hole 2211, increasing the water output of the outer dust box 2200, but it also reduces the risk of the second control plate 2212 adsorbing onto the side wall of the outer dust box 2200. In this embodiment, when the second control plate is in the second position, the stop limit protrusion limits the farthest position of the rotation of the second control plate 2212 and the outer dust box 2200. In some embodiments, the maximum included angle between the second control plate 2212 and the outer dust box 2200 is limited to 90°.

[0154] Optionally, in other embodiments, when the second control board 2212 pivots to the outer dust box 2200, the pivot mounting groove 43, pivot part 23 and stop limiting protrusion between the second control board 2212 and the mounting bracket 4 can also be provided between the second control board 2212 and the outer dust box 2200, which will not be described in detail here.

[0155] Optionally, the edge of the second control plate 2212 further extends with an overlapping portion 24. The overlapping portion 24 abuts against the inner side of the mounting bracket 4 when the second control plate 2212 is housed within the receiving cavity 42. The overlapping portion 24 is fixedly or detachably connected to the second control plate 2212. The overlapping portion 24 is located at the edge of the second control plate 2212. When the second control plate is in the first position, the second control plate 2212 is housed within the receiving cavity 42, and the overlapping portion 24 can abut against the inner side of the mounting bracket 4.

[0156] By means of the above method, the sealing performance of the second control board 2212 covering the second through hole 2211 is improved, reducing the amount of water entering the outer dust box 2200 from the gap between the second control board 2212 and the mounting bracket 4, thereby affecting the cleaning efficiency of the cleaning equipment.

[0157] In some embodiments, the outer dust box 2200 of the filter assembly 10 is approximately polymorphic, i.e., it has multiple sidewalls, and the second through hole and the second control plate 2212 may be disposed on at least one sidewall of the outer dust box.

[0158] When the outer dust box of the filter assembly has only one second through hole 2211, a first type of second control plate 2212 and a second counterweight block with a density greater than 1 g / cm3 can be installed at the second through hole 2211. Alternatively, a second type of second control plate 2212, a second counterweight block with a density less than 1 g / cm3 and a moving part 32 can be installed at the second through hole 2211.

[0159] When the outer dust box has two second through holes 2211, a first type of second control plate 2212 and a second counterweight with a density greater than 1 g / cm3 can be installed at both second through holes 2211. Alternatively, a second type of second control plate 2212, a second counterweight with a density less than 1 g / cm3, and a moving part 32 can be installed at both second through holes 2211. Alternatively, a first type of second control plate 2212 and a second counterweight with a density greater than 1 g / cm3 can be installed at one second through hole 2211, and a second type of second control plate 2212, a second counterweight with a density less than 1 g / cm3, and a moving part 32 can be installed at the other second through hole 2211.

[0160] When the filter assembly 10 is provided with three or more second through holes 2211, the type of the second control plate 2212 and the type of the second counterweight block at the second through hole 2211 can be determined according to the actual situation, and will not be described in detail here.

[0161] Furthermore, the shape of the aforementioned second through hole 2211 can be a regular shape or an irregular shape. A regular shape can be a regular polygon, a circle, etc. An irregular shape can be an arc or a combination of folds. The shape of the second control plate 2212 can be the same as or different from the shape of the second through hole 2211. When the shape of the second control plate 2212 is different from the shape of the second through hole 2211, as long as the second control plate is in the first position, it can completely cover the second through hole 2211; its specific shape is not limited.

[0162] It is understood that the second control board 2212 of the filter assembly 10 provided in this application embodiment is also provided with a second filter layer. When the second control board 2212 is not turned on, the second filter layer plays a role in filtering impurities, so as to avoid affecting the normal working state of the cleaning equipment due to the setting of the second control board 2212. The second filter layer can be set in a position that avoids the setting position of the second counterweight block, and its specific setting position and form are not limited here.

[0163] The aforementioned second control board 2212 can also be movably connected to other locations on the filter assembly, as long as it increases the fluid flow rate at the outlet of the cleaning equipment. Its connection structure is similar to the above results and will not be described in detail here. In other words, the location of the second control board 2212 can have multiple options, and its specific location can be determined according to the actual situation.

[0164] In some embodiments, the cleaning device includes a housing 1000, within which a receiving cavity 1100 is formed. A filter assembly 2000 and a water pump assembly 3000 are disposed within the receiving cavity 1100. The housing 1000 also has an inlet 1200 and an outlet 1300. The inlet 1200 is connected to the filter assembly 2000, and the water pump assembly 3000 is connected to both the filter assembly 2000 and the outlet 1300. The water pump assembly 3000 drives external water to flow from the inlet 1200 through the filter assembly 2000 to the outlet 1300, where it is discharged.

[0165] When the cleaning equipment cleans the bottom of the pool, the second control board is in the first position. At this time, the second control board 2212 covers the second through hole 2211. The water pump assembly 3000 is used to guide the water flow from the inlet 1200 into the filter assembly 2000. After being filtered by the outer dust box and / or inner dust box of the filter assembly 2000, the water enters the first water flow channel or the second water flow channel, and then enters the first drainage channel and is discharged through the outlet 1300.

[0166] As the cleaning equipment moves from the bottom of the pool to the pool wall, the second control plate rotates from the first position to the second position under the action of the second counterweight. At this time, the second control plate 2212 opens at least part of the second through hole 2211. In addition to guiding the water flow from the inlet 1200 into the filter assembly 2000, filtering through the outer dust box and / or inner dust box of the filter assembly 2000, and then entering the first water flow channel or the second water flow channel, and then entering the first drainage channel and being discharged through the outlet 1300, the water pump assembly 3000 also guides the liquid inside the filter assembly 2000 through at least part of the second through hole on its side wall into the first water flow channel, and then into the first drainage channel and being discharged through the outlet 1300, thereby increasing the drainage volume of the outlet and increasing the pressure of the cleaning equipment on the pool wall.

[0167] When the cleaning equipment is operating on the pool wall, the second control panel is in the second position. At this time, the second control panel 2212 opens at least part of the second through holes 2211 (more or larger number of second through holes than in the previous process). In the above process, the water pump assembly 3000 is used to guide the water flow from the inlet 1200 into the filter assembly 2000 in sequence, through at least part of the second through holes on the filter assembly 2000 into the first water flow channel, and then into the first drainage channel and discharged through the outlet 1300 in greater quantity, further increasing the drainage volume of the outlet and further increasing the pressure of the cleaning equipment on the pool wall.

[0168] In one embodiment, the second control plate 2212 is pivotally connected to the dust bin 2100, and the second through hole 2211 is also provided on the dust bin 2100. The second control plate 2212 pivotally connected to the dust bin 20 has the same structure as the second control plate 2212 pivotally connected to the outer dust box 2200, and will not be described in detail here.

[0169] In one embodiment, the water pump assembly includes a water pump 3100 and a water pump housing 3200. The area of ​​the second through hole 2211 of the filter assembly is larger than the cross-sectional area of ​​the water inlet of the water pump housing 3200. This larger area of ​​the second through hole 2211 increases the water outlet area of ​​the filter assembly, ensuring that the water flow rate in the filter assembly is greater than the water inlet flow rate of the water pump assembly 3100. This guarantees that the water flow rate requirement of the water pump assembly 3200 is always met, even when the filter is blocked or climbing a slope, thereby maintaining stable performance.

[0170] The aforementioned water pump 3100 also includes an impeller and a water pump motor. The output end of the water pump motor is connected to the impeller, which is located inside the water pump housing. The water pump motor drives the impeller to rotate inside the water pump housing, thereby providing power to the water flow channel.
