Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to a filtration device and an underwater swimming pool cleaning robot having the same. Background Art

[0002] As an important component of the underwater pool cleaning robot, the filtering device can filter the water flow sucked into the robot body during the operation of the underwater pool robot and absorb the total impurities in the water body to further improve the cleaning ability of the underwater pool cleaning robot.

[0003] Existing underwater pool cleaning robots usually use an integrated filter element to filter the water flow. The filter element has a small filtering area and often needs to be replaced and cleaned. However, due to its integrated structure, it is not easy to disassemble and replace. In addition, the installation structure of the traditional filter element and other components inside the cleaning robot is complicated, which not only wastes space inside the cleaning robot, but also further increases the difficulty of disassembling and cleaning the filter device. Utility Model Content

[0004] The technical problem solved by the present invention is to address the defects in the above-mentioned prior art and provide a filtering device and an underwater pool cleaning robot having the same, so as to solve at least one problem raised in the above-mentioned background technology. The specific solution is as follows:

[0005] In a first aspect, a filter device is provided, comprising a housing and one or more filter layers located within the housing; the housing comprises an upper housing and a lower housing, both surfaces of which are provided with a filter permeable structure. The upper housing comprises a receiving groove, and the lower housing has a retaining structure on an edge facing the receiving groove that engages with the inner edge of the receiving groove, thereby forming a receiving space between the receiving groove of the upper housing and the lower housing.

[0006] The filter body is located in the accommodating space, and the area where the filter water permeable structure is located covers the area where the filter body is located, so that external water flows into the filter body from the filter water permeable structure on one side and is discharged from the filter water permeable structure on the other side.

[0007] In some specific embodiments, the pore size of the filter and water-permeable structure located in the upper shell is smaller than the pore size of the filter and water-permeable structure located in the lower shell.

[0008] In some specific embodiments, the filter and water-permeable structure includes a filter layer disposed on a side of the upper and / or lower housing facing the interior of the accommodation space. The filter layer not only prevents the filter element within the housing from falling out of the housing but also provides a preliminary interception of larger particles of dirt for the filter device.

[0009] In some specific embodiments, central portions of the upper shell and the lower shell are both provided with corresponding central connecting holes, and the central connecting holes are used to allow an external fixing structure to pass through to fix the shell to an external mechanism.

[0010] In some specific embodiments, auxiliary mounting positions that are symmetrically arranged on the outer edge of the upper shell and are protruding outward or recessed inward relative to the center of the upper shell are provided.

[0011] In some specific embodiments, the size of the filter body is consistent with the size of the accommodating space, or the thickness of the filter body is less than or equal to the height of the limiting structure; the plane where the filter body is located is parallel to the plane where the filter permeable structure is located.

[0012] In some specific embodiments, the filter body includes a sponge filter layer, and / or an activated carbon filter layer, and / or a membrane filter layer, and / or a pressure plate layer, and / or a nanomaterial filter layer. It should be noted that the present application does not specifically limit the material composition of each filter layer used in the filter body and the installation order of different material layers. In actual applications, the filter body may include one or more of these different material layers, wherein the pressure plate layer may be a partition material provided with multiple water-permeable through holes, and the membrane filter layer may be composed of a water-permeable membrane material. In actual applications, a pressure plate layer or a membrane filter layer may be provided on a filter layer composed of a porous loose structure such as an activated carbon filter layer to maintain the relative position stability between the filter layers.

[0013] In some specific embodiments, a snap groove is provided on the edge of the upper housing in a predetermined first direction perpendicular to the plane of the upper housing. A snap member is provided on the lower housing at a position corresponding to the snap groove; the snap member engages with the snap groove in the first direction to securely connect the lower housing to the upper housing. The use of the snap member and the snap groove further simplifies the mounting structure between the upper and lower housings, allowing for faster disassembly of the housing and replacement of the filter element during actual use.

[0014] In some specific embodiments, mounting screw holes are provided on the edges of the upper shell and / or the lower shell for mating with external structures. In actual applications, in addition to being secured by the upper shell's receiving groove and the lower shell's retaining structure, the upper shell and the lower shell can also be mounted and assembled into a housing using mounting screw holes.

[0015] Secondly, an underwater pool cleaning robot is proposed, comprising a robot body and a filtering device according to any of the aforementioned technical solutions. The robot body is provided with a water inlet and a water outlet. The filtering device is located between the water inlet and the water outlet of the robot body and is used to filter the water entering the robot body. In practical applications, the driving mechanism and other major components of the underwater pool cleaning robot can be tightly connected to the filtering device via a central connection hole in the filtering device housing. This allows the filtering device to be installed more closely with other components and structures within the cleaning robot, further saving internal installation space and reducing the overall size of the cleaning robot, making the cleaning robot even more compact.

[0016] Furthermore, the present application does not limit the specific number of filtering devices in a robot body. In actual applications, the robot body can also be provided with multiple installation slots that match the size of the filtering devices, so that the user can install one or more filtering devices in the installation slot according to the water conditions of the swimming pool to be cleaned, so as to further enhance the cleaning effect of the underwater pool cleaning robot.

[0017] Beneficial effects: The present application proposes a filtering device and an underwater swimming pool cleaning robot having the same, wherein the filtering device includes a shell and one or more filter bodies located inside the shell. By setting the shell as an upper shell and a lower shell, and providing a filtering and permeable structure on the surface of the upper shell and the lower shell, the user can quickly disassemble and clean the filtering device, and can also flexibly replace the filter body in the shell, which can effectively adapt to a variety of different water environments.

[0034] Example 1

[0035] This embodiment provides a filtering device, and the specific solution is as follows:

[0036] A filter device includes a housing 1 and one or more filter layers 3 located within the housing 1. The housing 1 includes an upper housing 11 and a lower housing 12, both surfaces of which are provided with a filter permeable structure 2. The upper housing 11 includes a receiving groove 111, and the lower housing 12 has a retaining structure 121 disposed on an edge facing the receiving groove 111, which engages with the inner edge of the receiving groove 111, thereby forming a receiving space between the receiving groove 111 of the upper housing 11 and the lower housing 12.

[0037] The filter body 3 is located in the accommodating space, and the area where the filter water permeable structure 2 is located covers the area where the filter body 3 is located, so that external water flows into the filter body 3 from the filter water permeable structure 2 on one side and is discharged from the filter water permeable structure 2 on the other side.

[0038] In some specific embodiments, the pore size of the filter water-permeable structure 2 located in the upper shell 11 is smaller than the pore size of the filter water-permeable structure 2 located in the lower shell 12. In this way, progressive multi-layer filtration can be achieved, and the filtering effect is better. Among them, the filter water-permeable structure 2 includes a filter mesh layer; the filter mesh layer is arranged on the side of the upper shell 11 and / or the lower shell 12 facing the inside of the accommodating space. By providing the filter mesh layer, not only can the filter body 3 inside the shell 1 be prevented from falling out of the shell 1, but also larger particulate dirt can be preliminarily intercepted for the filter device. In actual applications, when the filter body 3 structure is stable and does not include relatively dispersed particles and other substances, the filter water-permeable structure 2 can also be a hollow structure, so that the part of the filter layer relative to the position of the hollow structure can directly contact the outside world.

[0039] In some specific embodiments, the middle portions of the upper shell 11 and the lower shell 12 are both provided with corresponding central connecting holes 4 , and the central connecting holes 4 are used to allow an external fixing structure to pass through so as to fix the shell 1 on an external mechanism.

[0040] In some specific embodiments, the outer edge of the upper shell 11 is symmetrically provided with auxiliary mounting positions 41 that are protruding outward or recessed inward relative to the center of the upper shell 11, such as Figure 3 In actual application, further, at a position symmetrical to the center of the central connecting hole 4 of the housing 1, the upper housing 11 and the lower housing 12 are both provided with an inwardly recessed mounting structure to form a hand-grip position, making it easy for the user to pick up and install the filter device with their fingers.

[0041] In some specific embodiments, the size of the filter body 3 is consistent with the size of the accommodation space, or the thickness of the filter body 3 is less than or equal to the height of the limiting structure 121; the plane where the filter body 3 is located is parallel to the plane where the filter permeable structure 2 is located. Figure 1 、 Figure 2 shown.

[0042] In some specific embodiments, the filter body 3 includes a sponge filter layer 311, and / or an activated carbon filter layer 312, and / or a membrane filter layer 31, and / or a pressure plate layer, and / or a nanomaterial filter layer 313. It should be noted that the present application does not specifically limit the material composition of each filter layer 31 used in the filter body 3 and the installation order of different material layers. In actual applications, the filter body 3 may include one or more of these different material layers, wherein the pressure plate layer may be a partition material provided with a plurality of water-permeable through holes, and the membrane filter layer 31 may be composed of a water-permeable membrane material. In actual applications, a pressure plate layer or a membrane filter layer 31 may be provided on a filter layer 31 composed of a porous and loose structure such as an activated carbon filter layer 312 to maintain the relative position stability between the filter layers 31.

[0043] In a specific embodiment, the external water flow enters the filter body 3 through the filter permeable structure 2 of the upper shell 11, passes through the sponge filter layer 311, the activated carbon filter layer 312, and the nanomaterial filter layer 313 in the filter body 3, and then leaves through the filter permeable structure 2 of the lower shell 12, completing a filtration process. The structure of each layer of the filter body 3 is as follows. Figure 5 shown.

[0044] In some specific embodiments, a snap-fit ​​groove 112 is provided on the edge of the upper housing 11 in a predetermined first direction perpendicular to the plane of the upper housing 11. A snap-fit ​​member 122 is provided on the lower housing 12 at a position corresponding to the snap-fit ​​groove 112. The snap-fit ​​member 122 is configured to engage with the snap-fit ​​groove 112 in the first direction to securely connect the lower housing 12 to the upper housing 11. The use of the snap-fit ​​member 122 in conjunction with the snap-fit ​​groove 112 further simplifies the installation structure between the upper and lower housings 11 and 12, allowing for faster disassembly of the housing 1 and replacement of the filter element 3 during actual use.

[0045] In actual use, the height of the housing 1 along the predetermined first direction is less than the length and width of the housing 1 on the surface on which it is placed, resulting in a relatively flat overall shape of the housing 1. This increases the contact area between the filter 3 and the water, allowing a larger amount of water to flow through the filter 3 at once, further reducing the resistance caused by the filtration device to the movement of the underwater pool robot. It should be noted that this embodiment does not limit the surfaces of the upper housing 11 and the lower housing 12 to be flat. In actual use, the upper housing 11 and the lower housing 12 can also be configured to be outwardly convex or have a curvature as needed.

[0046] In some specific embodiments, mounting screw holes 5 are provided on the edges of the upper shell 11 and / or the lower shell 12 for mating with external structures. In actual applications, in addition to being fixed by the receiving groove 111 of the upper shell 11 and the limiting structure 121 of the lower shell 12, the upper shell 11 and the lower shell 12 can also be mounted and assembled into the shell 1 by installing screws or other connecting parts through the mounting screw holes 5. In one specific embodiment, the distribution of the mounting screw holes 5 is as follows: Figure 4 As shown, the overall structure after installation is as follows Figure 6 shown.

[0047] This embodiment proposes a filtering device, including a shell and one or more layers of filter bodies located inside the shell. By setting the shell into an upper shell and a lower shell, and providing a filtering and permeable structure on the surface of the upper shell and the lower shell, the user can quickly disassemble and clean the filtering device, and can also flexibly replace the filter body in the shell, which can effectively adapt to a variety of different water environments.

[0048] Example 2

[0049] This embodiment proposes an underwater swimming pool cleaning robot, the specific scheme is as follows:

[0050] An underwater pool cleaning robot comprises a robot body and a filtering device according to any of the aforementioned technical solutions. The robot body is provided with a water inlet and a water outlet. The filtering device is located between the inlet and outlet of the robot body and is used to filter water entering the robot body. In practical applications, the driving mechanism and other major components of the underwater pool cleaning robot can be tightly connected to the filtering device via the central connecting hole 4 in the filtering device housing. This allows the filtering device to be installed more closely with other components and structures within the cleaning robot, further reducing the internal installation space of the cleaning robot and the overall size of the cleaning robot, making the cleaning robot more compact.

[0051] Furthermore, the present application does not limit the specific number of filtering devices that can be included in a robot body. In actual applications, the robot body can also be provided with multiple installation slots that match the size of the filtering devices, so that the user can install one or more filtering devices in the installation slots according to the water conditions of the swimming pool to be cleaned, so as to further enhance the cleaning effect of the underwater pool cleaning robot.

[0052] This embodiment proposes an underwater swimming pool cleaning robot. By applying the filtering device in the aforementioned technical solution, the user can quickly disassemble and clean the filtering device, and can also flexibly replace the filter body in the shell; furthermore, the size of the cleaning robot can be reduced, so that the cleaning robot can effectively adapt to a variety of different water environments.

[0053] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
