[0046] As Figure 1As shown, the present application provides a filter device 100 that can be used in a pool cleaning device, and in particular, the filter device 100 can be used in a pool cleaning robot. The pool cleaning robot moves in a pool to clean the pool. The filter device 100 is at least partially located inside the pool cleaning robot, and fluid flows through the filter device 100 to achieve cleaning. A portion of the filter device 100 is located inside the pool cleaning robot, and another portion can be located outside the pool cleaning robot. The entire filter device 100 can be located outside the pool cleaning robot. The filter device 100 includes a water surface inlet that allows water flow to pass through. In particular, dirty liquid at the water surface can enter the interior of the filter device 100 through the water surface inlet. The water flow that enters the water surface inlet can be filtered by the filter device 100. In this way, the pool cleaning robot sucks in fluid with dirt through the water surface inlet during cleaning, and the fluid is processed by the filter device 100 inside, and then the water is discharged from the drain outlet.

[0047] The pool cleaning robot includes a housing that can serve as the base of the pool cleaning robot. The housing is typically designed in a streamlined manner to reduce underwater resistance, and is made of plastic or metal. The pool cleaning robot also includes a power system that includes a drive wheel or a propeller that can propel the housing to move, such as converting the energy of an electric motor into mechanical motion to achieve the forward movement of the pool cleaning robot in water.

[0048] Further, the filter device 100 is detachably connected to the housing. The filter device 100 is used to contain dirt. The filter device 100 can be installed inside the housing. Liquid in the pool can enter the filter device 100 through the water surface inlet. The filter device 100 filters the liquid so that the dirt is located in the filter device 100, and the pool cleaning robot discharges the filtered clean liquid from the pool cleaning robot. The filter device 100 can also be removed from the housing. The operator can remove the dirt in the filter device 100 to ensure the cleanliness of the filter device 100.

[0049] Specifically, the filtering device 100 comprises a body structure 110 for containing dirt and sundries. The body structure 110 can be configured as a substantially cubic structure or a substantially spherical structure. The body structure 110 can be made of plastic or metal and the like to have good structural performance. The body structure 110 has a filtering cavity member 111. The filtering cavity member 111 is configured as a hollow structure. The filtering cavity member 111 is used to contain dirt sucked into the fluid. The filtering device 100 can filter the dirt in the fluid so that the dirt is located in the filtering cavity member 111, and the cleaned fluid can be discharged. The body structure 110 is detachably connected with the shell. The body structure 110 and the shell can be connected together by clamping. The body structure 110 can be installed inside the shell, or the body structure 110 can be taken out of the shell.

[0050] The filtering device 100 further comprises an adsorption structure 120 rotatably arranged on the body structure 110. The rotation of the adsorption structure 120 can drive the water flow and the visible garbage on the water surface into the body structure 110. In order to be able to adsorb the dirt such as oil stains on the water surface, the adsorption structure 120 is provided with an adsorption material 160. The adsorption material 160 can adsorb the dirt on the water surface.

[0051] The adsorption material 160 can be made of various types of adsorption sponge or other materials that can adsorb oil stains. Preferably, the adsorption material 160 is made of adsorption sponge, paper material or oil absorption felt. In particular, the adsorption material 160 can adsorb oil stains, planktonic microorganisms and / or viscous substances on the water surface. The adsorption material 160 can be in contact with the water flow when the adsorption structure 120 rotates, and can effectively absorb the dirt on the water surface. During the filtering work of the filtering device 100, the dirt on the water surface can be effectively prevented from leaking with the water flow. While the adsorption structure 120 pushes the garbage on the water surface, the adsorption material 160 can simultaneously adsorb the oil stains and microorganisms on the water surface. The adsorption material 160 is detachably connected to the adsorption structure 120. The adsorption material 160 can be easily replaced. Thus, the adsorption material 160 that has adsorbed dirt can be detached, and new adsorption material 160 can be replaced.

Alternatively, the entire filter device 100 may be located outside the pool cleaning robot. The filter device 100 includes a water surface inlet through which water flows. Specifically, dirty liquid on the water surface can enter the interior of the filter device 100 through the water surface inlet. After flowing into the water surface inlet, the water is filtered by the filter device 100.

[0071] A pool cleaning robot includes a shell, which serves as the robot's foundation. The shell typically features a streamlined design to reduce underwater drag, and is often made of plastic or metal. The robot also includes a power system, which may consist of drive wheels or a propeller.

[0072] The filter device 100 is detachably connected to the housing. The filter device 100 is used to contain dirt. The filter device 100 can be installed inside the housing. Liquid in the pool enters the filter device 100 through the water surface inlet. The filter device 100 filters the liquid, trapping dirt within it, and then the pool cleaning robot discharges the filtered, clean liquid from the pool cleaning robot. The filter device 100 can also be removed from the housing. Operators can remove the dirt from the filter device 100, thus ensuring its cleanliness.

[0073] like Figure 1 As shown, the filter device 100 includes a body structure 110 for containing dirt and other debris. The body structure 110 can be constructed as a generally cubic or generally spherical structure. The body structure 110 can be made of materials such as plastic or metal to provide good structural performance. The body structure 110 has a filter chamber component 111. The filter chamber component 111 is constructed as a hollow structure. The filter chamber component 111 is used to contain dirt in the fluid being drawn in. The filter device 100 is capable of filtering dirt from the fluid, ensuring that the dirt is contained within the filter chamber component 111, and is capable of discharging the cleaned fluid. The body structure 110 is detachably connected to the housing. The body structure 110 and the housing can be connected together by a snap-fit ​​mechanism. The body structure 110 can be installed inside the housing, or the body structure 110 can be removed from the housing.

[0074] The filter device 100 also includes an adsorption structure 120, which is rotatably mounted on the main body structure 110. The rotation of the adsorption structure 120 allows water flow and visible debris on the water surface to enter the main body structure 110. To adsorb oil stains and other dirt from the water surface, the adsorption structure 120 is equipped with an adsorption material 160. The adsorption material 160 is capable of adsorbing dirt from the water surface.

[0075] The absorbent material 160 can be made of various types of absorbent sponges or other oil-absorbing materials. Preferably, the absorbent material 160 is made of absorbent sponge, paper material, or oil-absorbing felt. In particular, the absorbent material 160 can absorb oil stains, planktonic microorganisms, and / or viscous substances on the water surface. The absorbent material 160 can come into contact with the water flow when the adsorption structure 120 rotates and can effectively absorb dirt on the water surface. When the filter device 100 is working, it can effectively prevent dirt on the water surface from leaking out with the water flow. While the adsorption structure 120 pushes in the debris on the water surface, the absorbent material 160 can simultaneously absorb oil stains and microorganisms on the water surface. The absorbent material 160 is detachably connected to the adsorption structure 120. The absorbent material 160 can be easily replaced. Thus, the adsorbent material 160 that has absorbed dirt can be removed and replaced with a new adsorbent material 160.

[0076] The swimming pool cleaning robot according to this application includes a filtration device 100, at least partially located inside the robot. The filtration device 100 includes a water surface inlet, through which water flows and is filtered. The robot also includes an adsorption structure 120 disposed on its shell. This allows the robot to adsorb dirt through the adsorption structure 120. Alternatively, the adsorption structure 120 can be disposed on the filtration device 100, and an adsorption material 160 can be provided on it. This allows the adsorption material 160 to come into contact with the water flow when the adsorption structure 120 rotates, effectively absorbing dirt from the water surface. While the adsorption structure 120 removes debris from the water surface, the adsorption material 160 simultaneously absorbs oil and microorganisms, achieving a higher level of water surface cleaning and effectively preventing dirt from leaking out with the water flow.

[0077] The adsorption structure 120 is rotatable, guiding water flow into the water surface inlet. The rotation of the adsorption structure 120 carries water and visible debris from the water surface into the inlet. To adsorb oil stains and other contaminants from the water surface, the adsorption structure 120 is equipped with adsorption material 160. Adsorption material 160 adsorbs surface contaminants. When the adsorption structure 120 rotates, the adsorption material 160 comes into contact with the water flow and effectively absorbs surface contaminants. During filtration operation of the filter device 100, leakage of surface contaminants is effectively prevented. While the adsorption structure 120 removes surface debris, the adsorption material 160 simultaneously absorbs oil stains and microorganisms from the water surface.

[0078] In embodiments of this disclosure, the adsorption structure 120 includes a rolling member 130 and a blade member 140, the blade member 140 being rotatably connected to the body structure 110 via the rolling member 130. The rolling member 130 is rotatably connected to the body structure 110. Rotation of the rolling member 130 can drive water flow and visible debris on the water surface into the water inlet.

[0079] Adsorbent material 160 is disposed on the surface of blade member 140. Adsorbent material 160 is connected to blade member 140 via a connector, or by adhesive bonding. The connector can be a bolt or screw, etc. Further, adsorbent material 160 can be disposed on the surface of blade unit 143. Adsorbent material 160 is connected to blade unit 143 via a connector, or by adhesive bonding. The connector can be a bolt or screw, etc. Blade member 140 includes a first surface 146 and a second surface 147, the first surface 146 and the second surface 147 facing opposite directions along the thickness direction of blade member 140. The first surface 146 can face the water flow direction. The second surface 147 can face away from the water flow direction. Adsorbent material 160 can be connected to the first surface 146 via a connector. Adsorbent material 160 is connected to the first surface 146 by adhesive bonding. Blade member 140 can be connected to the second surface 147 via a connector. The adsorbent material 160 is attached to the second surface 147 by adhesive bonding.
