[0025] Figure 1A-1B The diagram schematically illustrates the external appearance of an automatic pool cleaning device 100 according to an embodiment of the present disclosure. The automatic pool cleaning device 100 can perform cleaning operations on the bottom, walls, water, and surface of a pool (e.g., a swimming pool) as needed. Figure 1A The front of the automatic pool cleaning device 100 is schematically shown. Figure 1B The rear side of the automatic pool cleaning device 100 is schematically shown, such as Figure 1A-1BAs shown, the automatic pool cleaning device 100 may include structures / components such as a traveling mechanism 110, cleaning mechanisms 120 and 130; wherein, the traveling mechanism 110 drives the automatic pool cleaning device 100 to move; the first cleaning mechanism 120 and the second cleaning mechanism 130 are used, for example, to clean garbage in the water, at the bottom of the water, and on the surface of the water, and to clean dirt on the bottom and walls of the pool. As an example, Figure 1A-1B The schematic diagram shows that the traveling mechanism 110 may include tracked traveling units on both sides of the lower part of the automatic pool cleaning device 100, allowing the pool cleaning unit to travel along the bottom or walls of the pool to perform cleaning operations. However, the traveling units are not limited to... Figure 1A-1B The type shown can include, for example, wheeled travel units, without limitation.

[0026] It should be understood that Figure 1A-1B The automatic water tank cleaning device 100 shown is merely an example. Those skilled in the art can make changes to it in one or more aspects such as appearance, structure, layout, components, and functions according to actual needs, without departing from the principles of this disclosure.

[0027] Figure 2A-2B A filtration device for use in an automatic pool cleaning system according to an embodiment of the present disclosure is illustrated schematically. As an example, the filtration device is detachably mounted in the automatic pool cleaning system. Figure 2A-2B As shown, the filtration device 20 includes a first filter basket 210 and a second filter basket 220. The first filter basket 210 includes a first filter frame 2110 and a first filter screen 2120 disposed on the first filter frame; the second filter basket 220 includes a second filter frame 2210 and a second filter screen 2220 disposed on the second filter frame. Figure 2A This schematically illustrates the installation of the second filter basket 220 into the first filter basket 210. Figure 2B The illustration schematically shows the process of removing the second filter basket 220 from the first filter basket 210. For example... Figure 2A-2B As shown, the second filter basket 220 is detachably installed into the first filter basket 210. According to an embodiment of this disclosure, the pore size of the second filter screen 2220 is smaller than that of the first filter screen 2120.

[0028] As an example, the second filter basket 220 can be detachably installed into the first filter basket 210. This means that the second filter basket 220 can be directly placed into the first filter basket 210 or directly removed from the first filter basket 210 without the need for a separate connection structure. Of course, a separate connection structure can also be provided for the detachable connection of the two filter baskets.

[0029] According to embodiments of this disclosure, since the pore size of the filter screen in the second filter basket is smaller than that in the first filter basket, the second filter basket provides finer filtration and can remove finer particles of dirt. Furthermore, since the second filter basket is detachably installed in the first filter basket, depending on actual needs—for example, when finer filtration of the water in the pool is required, i.e., when smaller particles need to be removed—the second filter basket can be installed in the first filter basket so that smaller particles can be filtered out via the second filter screen. When there is no such need, the second filter basket can be left out of the first filter basket, and the water can be filtered using only the filter screen of the first filter basket. This improves the flexibility of the filtration device in meeting different filtration needs.

[0030] According to an embodiment of this disclosure, in the above-described filtering device, the second filter frame includes a second side support member, and the second filter screen is sleeved on the outside of the second side support member or disposed inside the second side support member.

[0031] As an example, Figure 3A The diagram schematically illustrates one structure of the second filter basket. For example... Figure 3A As shown, the second filter basket 220 includes a second filter frame 2210, the second filter frame 2210 includes a second side support member 2230, wherein the second filter screen 2220 is sleeved on the outside of the second side support member 2230.

[0032] As another example, the second filter screen can also be disposed inside the side support of the second filter basket, for example, by fitting the second filter screen onto the side support of the second filter basket from inside the second filter basket. Those skilled in the art can arrange the position of the second filter screen according to actual design requirements, and no limitations are imposed here. As an example, Figure 4A The diagram schematically illustrates one structure of the first filter frame 2110 of the first filter basket. (Example) Figure 4A As shown, the first filter frame 2110 can form a first cavity with the first filter screen (not shown in FIG4) having a first opening at the top, through which the second filter basket can be detachably installed in the first filter basket.

[0033] As an example, the first filter screen can be detachably installed onto the first filter frame as a whole. For example, it can be fitted onto the first filter frame from the outside or inside as a mesh sleeve with an upper opening corresponding to the first opening; or, filter screen pieces can be correspondingly set on the frame holes of the first filter frame. For those skilled in the art, the installation method of the first filter screen can be flexibly selected according to actual needs, and the installation method of the first filter screen and the first filter frame is not limited here.

[0034] Optionally, such as Figure 4A As shown, the first filter frame 2110 includes a first wall, on which a first water inlet 2160 may be provided.

[0035] In one possible implementation, the first water inlet is located on the bottom wall of the first filter frame. It is understood that the first water inlet can be located on any wall of the first filter frame, such as the side wall, as needed.

[0036] As another example, Figure 4B This schematically illustrates another structure of the first filter frame 2110. (As shown...) Figure 4B As shown, the first filter basket also includes an openable and closable top cover 2180 that cooperates with the first filter frame 2110, the top cover being able to close the first opening.

[0037] although Figure 4B The diagram schematically shows the top cover 2180 connected to the first filter frame 2110. However, the top cover can also be configured to be separable from the first filter frame, provided that when the first filter basket is installed in the automatic water tank cleaning device, the top cover can close the upper opening of the first cavity formed by the first filter frame and the first filter screen. The installation form of the top cover and the first filter frame is not limited.

[0038] As an example, such as Figure 3A As shown, in the above-mentioned filtration device, the second filter frame 2210 and the second filter screen 2220 form a second cavity with a second opening at the top; when the second filter basket is installed in the first filter basket, water entering through the first inlet enters the second cavity and is filtered by the second filter screen. After the micro dust particles in the water are filtered out, the water is then filtered by the first filter screen of the first filter basket and discharged from the filtration device.

[0039] As an example, in the above-mentioned filtration device, the second filter screen is a one-piece molded structure.

[0040] As an example, the second filter is made of fibrous material, including nonwoven materials such as polyester fibers or polyester fibers.

[0041] Figure 3B An alternative structure for the second filter basket is illustrated schematically. (See diagram.) Figure 3B As shown, the second filter screen 2220 is detachably connected to the second filter frame 2210 by fasteners 2260 and / or fasteners 2270, wherein the fasteners 2260 and 2270 are fixedly connected to the upper and / or lower parts of the second filter screen 2220.

[0042] Furthermore, as an example, such as Figure 2A-2BAs shown, a handle can also be provided at the second opening of the second filter frame 2210 of the second filter basket 220 to facilitate the removal of the second filter basket from the first filter basket, thereby cleaning the second filter basket, replacing the second filter screen, or cleaning the garbage / dirt trapped in the second filter basket.

[0043] As an example, such as Figures 3A-3B As shown, in the second filter basket 220, the second filter frame 2210 includes a second wall, on which a water inlet 2280 is provided, which can communicate with the first water inlet.

[0044] Possibly, the first water inlet protrudes from the first wall of the first filter frame 2110 into the interior of the first cavity, and the water inlet 2280 surrounds the first water inlet, so that when the second filter basket is installed in the first filter basket, the water entering through the first water inlet directly enters the second cavity.

[0045] In one possible implementation, the inlet 2280 is disposed on the bottom wall of the second filter frame 2210.

[0046] As another example, the second filter screen may include a bottom wall with a corresponding water inlet that can communicate with the first water inlet. In this case, the second filter frame itself may not include a bottom wall, i.e., it may only have side supports. When the second filter screen is fitted onto the side supports of the second filter frame from the outside or inside, the water inlet on the bottom wall of the second filter screen can communicate with the first water inlet.

[0047] According to embodiments of this disclosure, in the second filter basket, the second filter screen is detachably connected to the second filter frame. This allows the second filter frame to be reused easily, while the second filter screen can be used as a disposable consumable.

[0048] Optionally, in the above-mentioned filtration device, a one-way valve is provided at the first inlet. Thus, when water carrying garbage / dirt is driven to enter the filtration device through the first inlet, the one-way valve opens; and when the water flow stops entering the filtration device through the first inlet, the one-way valve automatically closes, thereby preventing the garbage / dirt trapped in the filtration device from flowing out of the filtration device.

[0049] According to another aspect of this disclosure, an automatic water tank cleaning device is proposed, which includes the above-described filtration device, wherein the filtration device is detachably installed in the automatic water tank cleaning device.

[0050] Therefore, various aspects of this disclosure have been presented above with reference to various apparatuses and methods. These apparatuses and methods are illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented in hardware or software depends on the specific application and the design constraints on the overall system.

[0051] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "setting," "connection," "linking," "fixing," and "coupling," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communicative connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.
