[0062] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present application and do not limit the present application.

[0063] like Figure 1 As shown, the present application provides a filtering device 100, which can be used in a swimming pool cleaning device, and in particular, the filtering device 100 can be used in a swimming pool robot. The swimming pool cleaning robot cleans in the swimming pool while moving. The filtering device 100 is installed in the swimming pool robot, and a water pump is used to drive the fluid to flow through the filtering device 100 to achieve a cleaning effect. During the cleaning process, the swimming pool cleaning robot inhales the dirty fluid through the water suction port, and after being processed by the internal filtering device 100, the water is discharged from the drain port.

[0064] The pool robot includes a fuselage, which can serve as the basis of the pool robot. The fuselage is usually streamlined to reduce underwater resistance, and the material is mostly plastic or metal. The pool robot also includes a power system, which includes a drive wheel or propeller, which can propel the fuselage to move, such as converting the energy of the motor into mechanical motion, so as to achieve the forward movement of the pool robot in the water.

[0065] Further, the filter device 100 is detachably connected to the body. The filter device 100 is used to contain dirt. The filter device 100 can be installed inside the body. The liquid in the swimming pool can enter the filter device 100 through the water suction port. The filter device 100 filters the liquid so that the dirt is located in the filter device 100, and the swimming pool robot then discharges the filtered clean liquid from the swimming pool robot. The filter device 100 can also be taken out of the body. The operator can take out the dirt in the filter device 100, thereby ensuring the cleanliness of the filter device 100.

[0066] Specifically, the filter device 100 includes a housing 110, and the housing 110 is used to accommodate dirt and other debris. The housing 110 can be constructed as a roughly cubic structure or a roughly spherical structure. The housing 110 can be made of materials such as plastic or metal to have good structural performance. The housing 110 has a cavity 111. The cavity 111 is constructed as a hollow structure. The cavity 111 is used to accommodate dirt sucked into the fluid. The filter device 100 can filter the dirt in the fluid so that the dirt is located in the cavity 111, and can discharge the cleaned fluid.

[0067] The housing 110 is detachably connected to the body. The housing 110 and the body can be connected together by snapping. The housing 110 can be installed inside the body, or the housing 110 can be removed from the body. In order to facilitate the operator to take out or put in, the filter device 100 also includes a handle 101, which is connected to the housing 110. The handle 101 is rotatably connected to the housing 110. Further, the housing 110 includes a top wall 112, which is connected to the handle 101. In this embodiment, the top wall 112 of the housing 110 faces the liquid surface of the fluid. The top wall 112 of the housing 110 faces the top of the swimming pool. The top wall 112 of the housing 110 is provided with a pivot shaft 102, which is connected to the handle 101. The handle 101 can rotate relative to the housing 110 to facilitate the operator to hold the handle 101.

[0068] In order to facilitate the discharge of dirt inside the housing 110, Figure 2As shown, the housing 110 also includes a drain port 115, which is communicated with the cavity 111. The drain port 115 is located at the top and / or bottom of the housing 110. The filtering device 100 also includes a top cover plate 116, which is connected to the top of the housing 110. The top cover plate 116 is movable relative to the housing 110. The top cover plate 116 can open the drain port 115 at the top of the housing 110. The top cover plate 116 can also close the drain port 115 at the top of the housing 110. One end of the top cover plate 116 is hinged to the housing 110, and the other end of the top cover plate 116 is engaged with the housing 110. One end of the top cover plate 116 is hinged to the housing 110 through the pivot shaft 102. The top cover plate 116 and the handle 101 are both hinged to the housing 110 through the same pivot shaft 102.

[0069] The top cover 116 can move between an open position and a closed position. The top cover 116 in the open position opens the top drain port 115 so that the cavity 111 is in communication with the outside of the filter device 100, and dirt inside the cavity 111 is discharged to the outside of the filter device 100 through the top drain port 115. The top cover 116 in the closed position can close the top drain port 115 to separate the cavity 111 from the outside of the filter device 100, thereby preventing dirt inside the cavity 111 from leaking into the body.

[0070] The filter device 100 further comprises a bottom cover plate 117, which is connected to the bottom of the housing 110. The bottom cover plate 117 is movable relative to the housing 110. The bottom cover plate 117 can open the sewage outlet at the bottom of the housing 110. The bottom cover plate 117 can also close the sewage outlet at the bottom of the housing 110. One end of the bottom cover plate 117 is hinged to the housing 110, and the other end of the bottom cover plate 117 is snap-fitted to the housing 110. One end of the bottom cover plate 117 is hinged to the housing 110 through an axis. The other end of the bottom cover plate 117 is provided with a buckle 118, and the bottom of the housing 110 is provided with a buckle positioning member 119, and the buckle 118 and the buckle positioning member 119 can snap-fit ​​together.

[0071] The bottom cover 117 can move between an open position and a closed position. The bottom cover 117 in the open position opens the bottom drain port so that the cavity 111 is in communication with the outside of the filter device 100, and the dirt inside the cavity 111 is discharged to the outside of the filter device 100 through the bottom drain port. The bottom cover 117 in the closed position can close the bottom drain port to separate the cavity 111 from the outside of the filter device 100, thereby preventing the dirt inside the cavity 111 from leaking into the body.

[0072] The filter device 100 further includes a moving member 130 and a filter member, wherein the moving member 130 is disposed in the housing 110. The moving member 130 can reciprocate relative to the housing 110. The moving member 130 is provided with a filter member. The filter member can filter dirt in the fluid so that the dirt is located in the cavity 111. The filter member is constructed as a structure such as a nylon net or a filter. The moving member 130 is constructed as a frame structure. The filter member is fixed to the moving member 130.

[0073] Optionally, the housing 110 is provided with a housing opening 120. The housing opening 120 can communicate the inside and the outside of the housing 110. Preferably, the housing opening 120 can communicate the cavity 111 and the outside of the housing 110. The housing opening 120 is covered with a filter member. The filter member is fixedly connected to the housing 110. The fluid in the cavity 111 flows to the outside of the filter device 100 through the filter member. Thus, the filter member can block dirt and clean the fluid, so that the cleaned fluid is discharged to the outside of the filter device 100.

[0074] The moving member 130 is disposed in the housing 110. The moving member 130 is located in the cavity 111. Figure 4 As shown, the cavity 111 includes a first chamber 121 and a second chamber 122, and the first chamber 121 and the second chamber 122 are connected. The first chamber 121 includes a housing opening 120, and the housing opening 120 is provided with a filter member. The second chamber 122 is provided with a moving member 130. The moving member 130 can move in the second chamber 122. The fluid flows through the first chamber 121 via the water inlet, and the fluid is discharged through the housing opening 120 of the first chamber 121. The fluid flows through the first chamber 121 via the water inlet, and then flows into the second chamber 122, and is discharged through the filter member of the moving member.

[0075] The fluid in the cavity 111 can flow to the outside of the filter device 100 through the moving member 130. The filter member on the moving member 130 can filter dirt. Figure 3 As shown, the mobile member 130 includes a mobile opening 134, and the mobile opening 134 can communicate the inside and outside of the mobile member 130. Preferably, the mobile opening 134 can communicate the inside of the mobile member 130 and the inside of the housing 110. The mobile opening 134 can communicate the inside of the mobile member 130 and the outside of the housing 110. The mobile opening 134 is covered with a filter member. The filter member is fixedly connected to the frame. The fluid in the cavity 111 flows to the outside of the filter device 100 through the filter member. Thus, dirt can be blocked by the filter member, and the cleaned fluid is discharged to the outside of the filter device 100.

[0076] The filter device 100 further includes a cleaning member 160, which is configured to clean the filter member during the reciprocating motion of the mobile member 130. The cleaning member 160 can realize self-cleaning of the filter device 100. Thus, the cleaning member 160 is built into the filter device 100, and the cleaning member 160 can clean the filter member in the filter device 100, and the filter member can be cleaned without taking out the filter device 100. The cleaning member 160 is located on the side of the filter member of the mobile member 130. The cleaning member 160 is used to clean the filter member. When the filter member filters dirt, dirt is easily accumulated on the filter member, which will cause the filter member to be blocked. The cleaning member 160 can clean the dirt on the filter member and ensure that the fluid can pass through the filter member smoothly. In particular, the cleaning member 160 cleans the filter member during the reciprocating motion of the mobile member 130, which ensures the cleanliness of the filter member when working, and there is no need for the operator to manually clean the filter member.

[0077] According to the filtering device 100 of the present application, it is used for a swimming pool robot. The filtering device 100 includes a housing 110, a moving member 130, a filtering member and a cleaning member 160. The housing 110 has a cavity 111. The moving member 130 is arranged in the housing 110. The moving member 130 can reciprocate relative to the housing 110. The filtering member is arranged on the moving member 130. The cleaning member 160 is configured to clean the filtering member during the reciprocating movement of the moving member 130. In this way, the cleaning member 160 cleans the filtering member during the reciprocating movement of the moving member 130, thereby ensuring the cleanliness of the filtering member during operation. There is no need for an operator to manually clean the filtering member, thereby extending the time when the filtering member is blocked, increasing the working time of the robot, and improving the cleaning efficiency.

[0078] The mobile member 130 can move along a first direction D1. The first direction D1 is parallel to the flow direction of the fluid. The fluid can apply a force to the mobile member 130 along the first direction D1. The first direction D1 is parallel to the movement direction of the fluid. The water pump can apply an adsorption force to move the fluid. The fluid can move along the first direction D1 toward the water pump. In particular, dirt in the fluid can be blocked by the filter member of the mobile member 130, and the dirt blocks the mesh of the filter member, so that the fluid pushes the mobile member 130 to move along the first direction D1. The fluid can push the mobile member 130 to move toward the outside of the filter device 100.

[0079] like Figure 4As shown, the housing 110 also includes a water inlet 103, which is used for fluid to pass through. The water inlet 103 is located at the bottom of the filter device 100. The water inlet 103 corresponds to the inlet at the bottom of the swimming pool robot. The housing 110 also includes a water inlet cover 104, which is pivotally connected to the housing 110. The water inlet cover 104 can open or close the water inlet 103. The water pump is actuated so that the fluid outside the filter device 100 flows into the inside of the filter device 100 through the water inlet 103. When the fluid flows from the outside of the filter device 100 to the inside, the fluid can push the water inlet cover 104 to open.

[0080] The water inlet cover plate 104 can move between an open position and a closed position. The water inlet cover plate 104 in the closed position closes the water inlet 103. The fluid can push the water inlet cover plate 104 in the closed position to move to the open position. The water inlet cover plate 104 in the open position can open the water inlet 103. The fluid enters the interior of the filter device 100 through the water inlet cover plate 104 in the open position.

[0081] Specifically, the moving member 130 is constructed as a three-dimensional frame structure. The moving member 130 can be integrally formed to have good structural strength to prevent breakage during movement or cleaning. Figure 2 As shown, the mobile member 130 includes a front frame 131 and a side frame 132, and the front frame 131 and the side frame 132 are connected. The front frame 131 is constructed as a frame structure. The side frame 132 is constructed as a frame structure. In this embodiment, the "front frame 131" refers to the frame of the mobile member 130 that is perpendicular to the first direction D1, and the "side frame 132" refers to the frame of the mobile member 130 that is parallel to the first direction D1. The thickness direction of the front frame 131 is parallel to the first direction D1. The thickness direction of the side frame 132 is perpendicular to the first direction D1. The thickness direction of the side frame 132 is parallel to the second direction D2. The second direction D2 is parallel to the first direction D1. The mobile member 130 is constructed as a frame structure. This facilitates production and manufacturing.

[0082] The front frame 131 is installed with a filter component. The filter component includes an end filter, and the end frame is provided with an end filter. The front frame 131 has a front frame opening 135, and the front frame opening 135 runs through the front frame 131. In particular, the front frame opening 135 runs through the front frame 131 along the first direction D1. The front frame opening 135 communicates the inside and outside of the frame. The front frame opening 135 is configured as a regular polygonal structure. For example, the front frame opening 135 is configured as a rectangular structure. This facilitates production and manufacturing, as well as the installation of the filter component. The fluid inside the frame flows to the outside of the frame through the front frame opening 135.

[0083] The end filter is connected to the front frame opening 135 of the front frame 131. The end filter is fixed to the wall of the front frame 131. The end filter covers the front frame opening 135. When the fluid flows, the front frame 131 is perpendicular to the flow direction of the fluid, and the dirt in the fluid will be blocked by the filter component of the front frame 131. The fluid inside the frame is filtered by the filter component of the front frame opening 135, and the filtered fluid flows to the outside of the frame. Thus, the moving member 130 can filter the fluid.

[0084] The side frame 132 is installed with a filter component. The filter component also includes a side filter component, and the side frame 132 is provided with a side filter component. The side frame 132 has a side frame opening 136, and the side frame opening 136 runs through the side frame 132. In particular, the side frame opening 136 runs through the side frame 132 along the second direction D2. The side frame opening 136 communicates the inside and outside of the frame. The side frame opening 136 is configured as a regular polygonal structure. For example, the side frame opening 136 is configured as a rectangular structure. This facilitates production and manufacturing, as well as the installation of the filter component. The fluid inside the frame flows to the outside of the frame through the side frame opening 136.

[0085] The side filter is connected to the side frame opening 136 of the side frame 132. The side filter is fixed to the wall of the side frame 132. The side filter covers the side frame opening 136. When the fluid flows, dirt in the fluid is blocked by the filter component of the side frame 132. The fluid inside the frame is filtered by the filter component of the side frame opening 136, and the filtered fluid flows to the outside of the frame. Thus, the moving member 130 can filter the fluid.

[0086] Further, the flow direction of the fluid is parallel to the side frame 132. It is understandable that the fluid flowing through the side frame 132 is less than the fluid flowing through the front frame 131. The dirt blocked by the front frame 131 is more than the dirt blocked by the side frame 132. The filter component of the front frame 131 is more easily clogged than the filter component of the side frame 132. The front filter is more easily clogged than the side filter. The mobile member 130 can move along the first direction D1. Therefore, the fluid can push the mobile member 130 to move along the first direction D1.

[0087] In particular, the internal pressure of the frame is greater than the external pressure of the frame. The fluid can push the movable member 130 to move along the first direction D1 toward the outside of the frame. There is a gap between the side frame 132 and the housing 110, so the fluid can be discharged. Since the filter component of the front frame 131 is blocked, the fluid is discharged through the filter component of the side frame 132. The filter component of the side frame 132 filters the dirt in the fluid. As a result, the fluid is discharged through the side frame 132, which can relieve pressure and ensure that there is a stable pressure difference between the inside and outside of the filter device 100, solve the problem of the pressure difference on both sides of the filter device 100 constantly changing, balance the pressure inside the movable member 130 and the pressure outside the movable member 130, and balance the pressure inside the filter device 100 and the pressure outside the filter device 100. In this way, a stable pressure difference working condition can be provided to the water pump, extending the service life of the motor.

[0088] In order to clean the dirt of the side frame 132, the cleaning member 160 cleans the filter member of the side frame 132. The cleaning member 160 is located on the side of the filter member of the side frame 132. The cleaning member 160 is located on the side of the filter member in a direction perpendicular to the first direction D1. Figure 3 As shown, the cleaning member 160 is located on the side of the filter member along the second direction D2. In particular, the cleaning member 160 is located on the side of the filter member of the side frame 132 along the second direction D2. The cleaning member 160 is located on the side of the side filter along the second direction D2. The cleaning member 160 is opposite to the filter member of the side frame 132. The cleaning member 160 can clean the filter member of the side frame 132 during the reciprocating motion of the moving member 130. Thus, it can be ensured that the filter member of the side frame 132 is cleaned and the clogging of the filter member of the side frame 132 is reduced.

[0089] like Figure 8 As shown, the cleaning member 160 includes a connecting portion 161 and a brush portion 162, and the connecting portion 161 and the brush portion 162 are connected. The length direction of the brush portion 162 is parallel to the height direction of the filter device 100. The length direction of the brush portion 162 is parallel to the third direction D3. The third direction D3 is perpendicular to the first direction D1. The third direction D3 is perpendicular to the second direction D2. The brush portion 162 faces the side frame 132. In particular, the brush portion 162 faces the side filter element. The brush portion 162 is fixed to the housing 110 through the connecting portion 161. The connecting portion 161 is fixed to the housing 110 by screws.

[0090] The connecting portion 161 includes a crossbar 163 and a vertical bar 164, and the crossbar 163 and the vertical bar 164 are vertically connected. The crossbar 163 is connected to the housing 110. The housing 110 includes a side wall 114, and the side wall 114 is located on the side of the connecting portion 161. A movable member 130 is arranged between the two side walls 114. The two side walls 114 are arranged opposite to each other along the second direction D2. The side wall 114 is connected to the crossbar 163. The side wall 114 is fixed together with the crossbar 163. Of course, the crossbar 163 can be removed from the side wall 114 for easy maintenance. The end of the crossbar 163 is provided with a protrusion, and the side wall 114 is provided with a hole, and the protrusion of the crossbar 163 is inserted into the hole of the side wall 114. Of course, the end of the crossbar 163 can also be provided with a hole 165, and the side wall 114 is provided with a protrusion, and the protrusion of the side wall 114 is inserted into the hole 165 of the crossbar 163. Both sides of the crossbar 163 are respectively connected to the two side walls 114. Both sides of the crossbar 163 are respectively inserted into the two side walls 114.

[0091] The vertical rod 164 is provided with a brush portion 162. The brush portion 162 of the vertical rod 164 faces the moving member 130. In particular, the brush portion 162 of the vertical rod 164 faces the side wall 114. The brush portion 162 includes bristles, and the bristles can clean the filter member. The bristles of the brush portion 162 are interference-fitted with the filter member. In particular, the bristles of the brush portion 162 face the filter member of the side frame 132. When the moving member 130 reciprocates, the bristles of the brush portion 162 exert a force on the filter member of the side frame 132, so that the bristles can exert a force on the filter member and brush the filter member.

[0092] For ease of installation, the top wall 112 is located above the cleaning member 160 along the third direction D3. Figure 1 As shown, the top wall 112 is provided with a limiting hole 123, and the limiting hole 123 is engaged with the cleaning member 160. In particular, the limiting hole 123 is engaged with the brush portion 162. A top shaft 166 is provided at the top of the connecting portion 161, and the top shaft 166 is engaged with the limiting hole 123. The connecting portion 161 includes at least two vertical rods 164, and at least two vertical rods 164 are each provided with a top shaft 166. The top wall 112 can be provided with at least two limiting holes 123, and at least two limiting holes 123 are respectively engaged with at least two top shafts 166.

[0093] The cleaning member 160 includes at least two brush parts 162, and the moving member 130 includes at least two side frames 132, and the at least two brush parts 162 face the at least two side frames 132 respectively. Thus, the brush parts 162 can brush the filter components of the side frames 132. The cleaning member 160 may include more brush parts 162, and the bristles of adjacent brush parts 162 face opposite directions. The bristles of the brush parts 162 are interference-fitted with the filter components of the side frames 132. Thus, the at least two brush parts 162 are respectively opposite to the filter components of the at least two side frames 132, ensuring that the brush parts 162 can clean the dirt of the filter components of the side frames 132.

[0094] Furthermore, if Figure 4 As shown, the filter device 100 further includes an elastic component 133, and the two ends of the elastic component 133 are respectively abutted against the housing 110 and the mobile member 130. The elastic component 133 can produce elastic deformation. The elastic component 133 can produce elastic deformation along the first direction D1. One end of the elastic component 133 is connected to the housing 110, and the other end is connected to the mobile member 130. The elastic component 133 can produce deformation with the movement of the mobile member 130.

[0095] The reciprocating motion of the movable member 130 relative to the housing 110 is achieved by starting and stopping the water pump and the elastic component 133. The water pump action can drive the fluid to flow, and the end filter blocks the dirt of the fluid. The end filter is blocked, and as the water pump continues to operate, the fluid continues to exert an outward force on the end filter. The movable member 130 includes an initial position and a moving position, and the fluid can push the end filter to move outward, so that the movable member 130 located at the initial position moves to the final position. The elastic component 133 can exert a rebound force on the movable member 130, so that the movable member 130 located at the final position moves to the initial position.

[0096] The mobile member 130 can reciprocate between an initial position and a final position. The initial position corresponds to the position of the mobile member 130 when the elastic component 133 is not deformed. The mobile member 130 at the initial position can move to the final position to compress the elastic component 133. The mobile member 130 at the initial position can move to the final position under the thrust caused by the movement of the fluid.

[0097] Further, the housing 110 also includes a seal, which is spaced apart from the side wall 114 along the second direction D2. The seal is configured as a plate-like structure. The housing 110 also includes a bottom wall 113, and the top wall 112 and the bottom wall 113 are spaced apart along the third direction D3. The top of the side wall 114 is connected to the top wall 112, and the bottom of the side wall 114 is connected to the bottom wall 113. A mobile space is formed between the two side walls 114, and the mobile member 130 is located in the mobile space. The seal is located in the mobile space. The fluid is discharged to the outside of the filter device 100 by the filter member of the end frame located in the initial position. The fluid is not discharged by the filter member of the side frame 132 located in the initial position.

[0098] In order to ensure that the mobile member 130 can move smoothly in the housing 110, the moving space of the housing 110 also includes a support plate 125, and the support plate 125 is located below the mobile member 130. The top of the seal is connected to the top wall 112, and the bottom of the seal is connected to the support plate 125. The support plate 125 can support the mobile member 130. In order to ensure the accuracy of the movement of the mobile member 130, the filter device 100 also includes a guide member, which is used to guide the reciprocating motion of the mobile member 130. The mobile member 130 can move linearly along the first direction D1. The guide member is arranged on the housing 110 and / or the mobile member 130.

[0099] As an optional implementation, Figure 7 As shown, a positioning member 126 is provided at the end of the support plate 125, and the positioning member 126 abuts against the mobile member 130 located at the initial position. The longitudinal section of the positioning member 126 is triangular. The elastic component 133 and the positioning member 126 can position the mobile member 130 located at the initial position. One end of the mobile member 130 located at the initial position along the first direction D1 abuts against the positioning member 126. The other end of the mobile member 130 located at the initial position along the first direction D1 abuts against the elastic component 133.

[0100] For example, the guide member is configured as a guide rail, which is provided to the mobile member 130. The guide rail protrudes from the outer surface of the mobile member 130 toward the direction of the housing 110. The housing 110 is provided with a groove, which corresponds to the guide rail. The groove and the guide rail cooperate. The guide rail can move in the groove. The guide rail moves along the extension direction of the groove. Thus, the reciprocating motion of the mobile member 130 can be guided. Of course, the guide rail can also be provided to the housing 110. The guide rail protrudes from the inner surface of the housing 110 toward the direction of the mobile member 130. The mobile member 130 is provided with a groove, which corresponds to the guide rail. The groove and the guide rail cooperate. The guide rail can move in the groove. The guide rail moves along the extension direction of the groove. Thus, the reciprocating motion of the mobile member 130 can be guided.

[0101] Specifically, Figure 2 and Figure 3 As shown, mobile member 130 comprises a first front frame 137 and two first side frames 138, and the two first side frames 138 are respectively located on both sides of the first front frame 137. Housing 110 also comprises a first seal 127, and a first space is formed between the first seal 127 and the sidewall 114. The first front frame 137 and the two first side frames 138 are all located in the first space. Fluid is discharged to the outside of mobile member 130 by the first front frame 137 located in the initial position. The first seal 127 blocks the fluid discharge from the filter member of the first side frame 138 located in the initial position. The first seal 127 and the first side frame 138 located in the initial position are closely fitted. The fluid from the filter member of the first side frame 138 located in the initial position will not be discharged by the first seal 127.

[0102] The mobile member 130 comprises a second front frame 139 and two second side frames 140, and the two second side frames 140 are respectively located on both sides of the second front frame 139. The housing 110 also comprises a second seal 128, and a second space is formed between the second seal 128 and the first seal 127. The second front frame 139 and the two second side frames 140 are all located in the second space. The fluid is discharged to the outside of the mobile member 130 by the second front frame 139 located in the initial position. The second seal 128 blocks the fluid discharge from the filter member of the second side frame 140 located in the initial position. The second seal 128 and the second side frame 140 located in the initial position are closely fitted. The fluid from the filter member of the second side frame 140 located in the initial position will not be discharged by the second seal 128.

[0103] The fluid pushes the mobile member 130, and the mobile member 130 compresses the elastic component 133. The mobile member 130 moves toward the outside of the filter device 100, and the side frame 132 moves toward the outside of the filter device 100. The side frame 132 protrudes from the seal. At least part of the filter member of the side frame 132 located in the final position protrudes from the seal. At least part of the side filter member located in the final position protrudes from the seal. The seal no longer blocks the fluid from the protruding filter member of the side frame 132. The fluid flows out and can be depressurized through the side frame 132, gradually reducing the pressure inside the mobile member 130. The side frame 132 located in the final position protrudes from the seal. The front frame 131 located in the final position compresses the elastic component 133.

[0104] Specifically, the fluid pushes the first front frame 137 to move toward the outside of the filter device 100, the first side frame 138 to move toward the outside of the filter device 100, and the first side frame 138 protrudes from the first seal 127. A portion of the filter member of the first side frame 138 protrudes from the first seal 127 toward the outside of the filter device 100. The fluid can be discharged through the first side frame 138. The first side frame 138 located at the final position protrudes from the seal. The first front frame 137 located at the final position compresses the elastic component 133.

[0105] The fluid pushes the second front frame 139 to move toward the outside of the filter device 100, and the second side frame 140 moves toward the outside of the filter device 100, and the second side frame 140 protrudes from the second sealing member 128. A portion of the filter member of the second side frame 140 protrudes from the second sealing member 128 toward the outside of the filter device 100. The fluid can be discharged through the second side frame 140. The second side frame 140 located at the final position protrudes from the sealing member. The second front frame 139 located at the final position compresses the elastic component 133.

[0106] Of course, the filter device 100 may also include more number of mobile components 130, such as two, three or more, and the plurality of mobile components 130 are all located in the housing 110 and are movable, which is not limited in this embodiment. The mobile component 130 may also include more number of front frames 131, side frames 132 and seals, and the number of seals matches the number of the front frames 131 and the side frames 132, which is not limited in this embodiment.

[0107] The mobile member 130 at the final position can compress the elastic component 133. The final position corresponds to the position of the mobile member 130 when the elastic component 133 is maximally deformed. The elastic force F2 generated by the elastic component 133 of the mobile member 130 at the final position resets the mobile member 130 after the water pump stops working. The mobile member 130 at the final position can move to the initial position. The elastic component 133 applies the elastic force F2 to the mobile member 130 at the final position to reset the mobile member 130.

[0108] The elastic component 133 can move the mobile member 130 back to its original position. The elastic component 133 drives the mobile member 130 to move from the final position to the initial position. The moving speed of the mobile member 130 driven by the elastic component 133 is faster than the moving speed of the mobile member 130 driven by the fluid. During the rapid movement of the mobile member 130, the cleaning component 160 cleans the filter component of the side frame 132. During the rapid movement of the mobile member 130, the cleaning component 160 cleans the filter component of the mobile member 130. Thus, the cleaning component 160 can brush the dirt of the filter component of the mobile member 130 and clean the blockage. In particular, during the rapid movement of the mobile member 130, the brush portion 162 of the cleaning component 160 brushes the filter component of the side frame 132. Thus, the cleaning component 160 can brush the dirt of the filter component of the side frame 132 and clean the blockage.

[0109] The elastic component 133 drives the moving member 130 to move quickly, and the dirt will fall off due to the rebound force of the elastic component 133. The elastic component 133 drives the moving member 130 to move quickly, and the dirt on the filter component of the moving member 130 will fall off due to the rebound force of the elastic component 133. The elastic component 133 drives the front frame 131 to move quickly, and the dirt on the filter component of the front frame 131 will fall off due to the rebound force of the elastic component 133. The elastic component 133 drives the side frame 132 to move quickly, and the dirt on the filter component of the side frame 132 will fall off due to the rebound force of the elastic component 133.

[0110] The elastic component 133 drives the moving member 130 to move quickly, and the moving member 130 can move quickly relative to the cleaning member 160, so that the cleaning member 160 can clean the filter member of the moving member 130. The elastic component 133 drives the front frame 131 to move quickly, and the front frame 131 can move quickly relative to the cleaning member 160, so that the cleaning member 160 can clean the filter member of the front frame 131. The elastic component 133 drives the side frame 132 to move quickly, and the side frame 132 can move quickly relative to the cleaning member 160, so that the cleaning member 160 can clean the filter member of the side frame 132.

[0111] The filter device 100 includes two elastic components 133, which are arranged at intervals along the second direction D2. The two elastic components 133 are respectively against the two sides of the mobile member 130. Both elastic components 133 can apply elastic force F2 to the mobile member 130 to ensure that the mobile member 130 is evenly stressed. The elastic component 133 includes an elastic component 141 and a connecting shaft 142, and the elastic component 141 is connected to the housing 110 through the connecting shaft 142. The elastic component 141 is configured as a spring. The spring can be elastically deformed along the first direction D1. The elastic component 141 is sleeved to the connecting shaft 142. The axial direction of the connecting shaft 142 is parallel to the first direction D1. The mobile member 130 includes a connecting hole 143, and the position of the connecting hole 143 corresponds to the position of the connecting shaft 142. The connecting shaft 142 can be inserted into the connecting hole 143 of the mobile member 130. In particular, the connecting shaft 142 can be inserted into the connecting hole 143 of the mobile member 130. The connection hole 143 is movable relative to the connection shaft 142 .

[0112] One end of the elastic member 141 abuts against the moving member 130. The other end of the elastic member 141 abuts against the housing 110. In order to prevent the moving member 130 from moving excessively, Figure 5 and Figure 6 As shown, the filter device 100 further includes a limiting member 171, which is disposed on the housing 110. The limiting member 171 is fixedly connected to the inner surface of the housing 110. The limiting member 171 protrudes from the housing 110. The limiting member 171 protrudes from the inner surface of the housing 110 along the second direction D2. Figure 3 As shown, one end of the connecting shaft 142 is connected to the limiting member 171, and the other end of the connecting shaft 142 is inserted into the connecting hole 143. The limiting member 171 limits the final position of the mobile member 130. The mobile member 130 at the final position abuts against the limiting member 171. The limiting member 171 can prevent the mobile member 130 at the final position from continuing to move. The limiting member 171 can limit the mobile member 130 at the final position. Thus, the mobile member 130 is prevented from moving excessively, and the mobile member 130 is ensured to move to a suitable position.

[0113] As an optional embodiment, the mobile member 130 further includes a connecting frame, which connects adjacent side frames 132. The side frames 132 can move relative to the sealing member. A side space is formed between adjacent side frames 132. The sealing member is located in the side space. The connecting frame of the mobile member 130 located in the final position can abut against the sealing member. The sealing member blocks the connecting frame located in the final position from continuing to move toward the outside of the filter device 100 along the first direction D1. Thus, the mobile member 130 is prevented from being separated from the housing 110.

[0114] For example, the mobile member 130 further includes a first connecting frame 144, which connects the first side frame 138 and the second side frame 140. A first side space 145 is provided between the first side frame 138 and the second side frame 140. The first sealing member 127 is located in the first side space 145. The first side frame 138 and the second side frame 140 are both movable relative to the first sealing member 127. The first connecting frame 144 moves along the first direction D1 relative to the first sealing member 127. The first connecting frame 144 located at the initial position moves to the final position relative to the first sealing member 127 along the first direction D1 toward the outside of the filter device 100. The first connecting frame 144 located at the final position moves to the initial position relative to the first sealing member 127 along the first direction D1 toward the inside of the filter device 100. The first connecting frame 144 located at the final position can abut against the first sealing member 127. The first sealing member 127 blocks the first connecting frame 144 located at the final position from continuing to move along the first direction D1 toward the outside of the filter device 100 , thereby preventing the moving member 130 from being disengaged from the housing 110 .

[0115] Combination Fig. 9 As shown, the water pump is activated, and the fluid flows in the first direction D1 in the forward direction. The fluid flowing in the forward direction is filtered by the filter component of the front frame 131. The fluid filtered by the filter component of the front frame 131 flows out in the first direction D1 in the forward direction. The forward inlet flow direction of the fluid is X1. The forward outlet flow direction of the fluid is X2. When the filter component of the front frame 131 is blocked, a pressure difference is formed on both sides of the filter component of the front frame 131, generating a pump suction force F1. The moving member 130 moves in the direction of the pump suction force F1. The cleaning member 160 and the filter component of the side frame 132 move relative to each other. The cleaning member 160 cleans the filter component of the side frame 132. The elastic component 133 is compressed by force. The moving member 130 and the seal are misaligned, and the local seal disappears. The fluid can flow out along the side space through the filter component of the side frame 132. The lateral outlet flow direction of the fluid can be Y1, and the lateral outlet flow direction of the fluid can also be Y2.

[0116] The water pump is turned off. The pump suction F1 disappears. The moving member 130 returns to its original position. The cleaning member 160 and the filter member of the side frame 132 move relative to each other. The cleaning member 160 cleans the filter member of the side frame 132.

[0117] According to the filter device 100 of the present application, the cleaning component 160 cleans the filter component during the reciprocating motion of the moving component 130, thereby ensuring the cleanliness of the filter component during operation. There is no need for an operator to manually clean the filter component, thereby reducing clogging of the filter component and ensuring a stable pressure difference between the inside and outside of the filter device 100. This provides a working condition with a stable pressure difference for the water pump, thereby extending the service life of the water pump, reducing the power of the water pump motor, ensuring endurance time, reducing motor overheating and overload, and reducing the risk of damage.

[0118] The filter device 100 of the present application can realize partial filter cleaning by utilizing the start and stop process of the water pump without the help of an additional motor drive, and the original loss energy is converted and utilized, with low cost and low overall weight. The filter device 100 of the present application realizes partial filter cleaning by utilizing the pressure difference change on both sides of the filter during the filter blockage process.

[0119] The present application also provides a swimming pool robot, which includes the above-mentioned filtering device 100.

[0120] According to the swimming pool robot of the present application, the swimming pool robot includes the above-mentioned filtering device 100, the filtering device 100 includes a housing 110, a moving member 130, a filtering member and a cleaning member 160, the housing 110 has a cavity 111, the moving member 130 is arranged in the housing 110, the moving member 130 can reciprocate relative to the housing 110, the filtering member is arranged on the moving member 130, and the cleaning member 160 is configured to clean the filtering member during the reciprocating movement of the moving member 130. In this way, the cleaning member cleans the filtering member during the reciprocating movement of the moving member, thereby ensuring the cleanliness of the filtering member during operation, extending the time when the filtering member is blocked, increasing the working time of the robot, and improving the cleaning efficiency.

[0121] like Fig.10 As shown, the present application also provides a cleaning method, which comprises the following steps:

[0122] The filtering device 100 is installed in the swimming pool robot.

[0123] The filter device 100 has a clean filter component, which is installed in a swimming pool robot.

[0124] Place the pool robot in the water and turn on the water pump.

[0125] The water pump is activated to drive the fluid to flow into the filter device 100. At this time, the pressure difference between the two sides of the filter member of the front frame 131 is equal to the spring force of the spring assembly. The moving member 130 does not move.

[0126] The fluid is filtered in the filter device 100 by the filter member of the moving member 130. In particular, the fluid is filtered in the filter device 100 by the filter member of the front frame 131. The fluid filtered by the filter member of the front frame 131 is discharged from the filter device 100. When the filter member of the front frame 131 is slightly clogged, the moving member 130 moves slightly to increase the filtering area so that the pressure difference on both sides of the filter member of the front frame 131 is balanced.

[0127] When the filter element of the moving member 130 is clogged, the fluid movement brings thrust to drive the moving member 130 to move. The fluid movement can drive the moving member 130 to move toward the outside of the filter device 100. The moving member 130 moves significantly to increase the filter area, so that the pressure difference on both sides of the filter element of the front frame 131 is balanced.

[0128] When the filter member of the front frame 131 is blocked, the fluid movement brings thrust to drive the front frame 131 to move. The fluid movement can drive the front frame 131 to move toward the outside of the filter device 100. The mobile member 130 can move to the final position. At this time, the mobile member 130 is in a fully pulled out state relative to the housing 110.

[0129] When the filter element of the front frame 131 is blocked, the fluid movement brings thrust to drive the front frame 131 to move the side frame 132. The fluid movement can drive the side frame 132 to move toward the outside of the filter device 100.

[0130] Since the filter components of the front frame 131 have been clogged, most of the fluid will be discharged through the side frame 132. Most of the fluid is filtered by the filter components of the side frame 132. The fluid is filtered by the filter components of the side frame 132. The fluid filtered by the filter components of the side frame 132 is discharged from the filter device 100. The fluid pressure inside the moving member 130 is released through the side frame 132.

[0131] The water pump is turned off. The fluid no longer continues to flow. The pressure of the fluid inside the mobile member 130 is reduced. The pressure difference on both sides of the filter component of the front frame 131 disappears, and the mobile member 130 is reset. The cleaning member 160 cleans the filter component of the side frame 132. The elastic component 133 applies a force to the mobile member 130. The elastic component 133 rebounds. The direction of the rebound of the elastic component 133 is opposite to the flow direction of the fluid. The elastic component 133 can move the mobile member 130 back to its original position. The elastic component 133 drives the mobile member 130 to move from the final position to the initial position.

[0132] The elastic component 133 drives the moving member 130 to move faster than the moving member 130 driven by the fluid. During the rapid movement of the moving member 130, the cleaning member 160 cleans the filter member of the side frame 132. During the rapid movement of the moving member 130, the cleaning member 160 cleans the filter member of the moving member 130. Thus, the cleaning member 160 can brush the dirt of the filter member of the moving member 130 and clean the blockage. In particular, during the rapid movement of the moving member 130, the brush portion 162 of the cleaning member 160 brushes the filter member of the side frame 132. Thus, the cleaning member 160 can brush the dirt of the filter member of the side frame 132 and clean the blockage.

[0133] The filter member of the side frame 132 is cleaned.

[0134] Turn the pump back on.

[0135] When the filter element of the front frame 131 is blocked, the pressure difference on both sides of the filter element of the front frame 131 is generated. The fluid movement brings thrust to drive the front frame 131 to move. The fluid movement can drive the front frame 131 to move toward the outside of the filter device 100. The mobile member 130 can move to the final position. During the movement of the mobile member 130, the cleaning member 160 cleans the filter element of the side frame 132. Thus, the pressure difference on both sides of the filter element of the front frame 131 is balanced. At this time, the mobile member 130 is in a fully pulled out state relative to the housing 110.
