[0033] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0034] Example 1

[0035] like Figures 1-3 As shown, this embodiment provides a filtration device 100 for underwater robots (hereinafter referred to as "filtration device body" or "filtration device" or "body"), including a filtration device 100 body. The bottom of the body is provided with a water inlet 101. A plurality of filter holes are provided on the side wall of the body. A hollow cavity is provided inside the body. At least three interconnected and surrounding side walls are provided on the side of the body. At least one side wall is an irregular structure or a curved structure. The irregular structure or curved structure is bent or inclined to each other in both the longitudinal and transverse directions, so that the side wall of the irregular structure forms a second filter cavity 102 towards the cavity or the outside of the filtration device 100 body. The left side of the side wall of the irregular structure is connected to a first side wall 110, and the right side of the side wall of the irregular structure is connected to a second side wall 111.

[0036] The underwater robot filter device 100 of this embodiment may or may not have a top cover. When it has a top cover, the top cover, side walls, and bottom wall together form an enclosed cavity, allowing waste to be collected within the cavity. When it does not have a top cover, after being installed on the underwater robot, the cover of the underwater robot contacts the top of the side wall of the filter device. Thus, the cover, side walls, and bottom wall of the underwater robot together form an enclosed cavity, which also allows waste to be collected within the cavity, achieving the same effect.

[0037] The irregularly shaped sidewalls create an uneven inner surface, allowing different types of waste to be swept to different areas for collection by water flow, thus achieving the effect of sorting and collecting waste.

[0038] In an embodiment, the side wall of the special-shaped structure comprises a first side ear 112 connected with the first side wall 110 and a second side ear 113 connected with the second side wall 111, and a filter wall 114 is arranged between the first side ear 112 and the second side ear 113, and a filter opening is arranged on the filter wall 114, the first side ear 112 and the second side ear 113. The first side ear 112 and the second side ear 113 are mainly to form different side surfaces, but in this embodiment, the inclination angle, length, swing direction and the like of the first side ear 112 and the second side ear 113 are not specifically required, as long as they are thus arranged, the effect of the utility model can be achieved.

[0039] The first side ear 112 and the second side ear 113 are placed obliquely in or out of the body of the filter device 100, so that different regions exist longitudinally on the side surface. The distance and contact area of the water flow all affect the flow rate of the water, so that the garbage is flushed to different regions for residence.

[0040] In an embodiment, the filter wall 114, the first side ear 112 and the second side ear 113 are connected into a U-shaped structure with thick upper part and thin lower part, or a wedge shape. The connecting part of the U-shaped structure can also be provided with square corners or round corners. When the square corners are provided, the cross section is also substantially in the shape of “”, and in this embodiment, the shape when provided can be adjusted according to the actual scene and requirements, and this embodiment does not exhaustively list them.

[0041] In an embodiment, the projection or cross section of the filter wall 114 is parallel to the edge of the water inlet 101. The parallel arrangement can make the water enter the water inlet 101 and smoothly reach each region without being blocked halfway.

[0042] In an embodiment, the first connecting wall 115 is further arranged between the first side wall 110 and the first side ear 112, and the second connecting wall 116 is further arranged between the second side wall 111 and the second side ear 113.

[0043] When the body of the filter device 100 is too large for the underwater robot, if the first side ear 112 and the second side ear 113 are directly arranged, the span between the first side ear 112 and the second side ear 113 is large, and at this time, the first connecting wall 115 and the second connecting wall 116 are added to make the structure more optimized and the effect more obvious.

[0044] In an embodiment, the filter opening or filter hole is provided with a filter body (not shown in the figure), and the filter body is one or a combination of a filter screen, filter cotton, filter paper, a filter bag, an activated carbon filter layer and a particle filter layer.

[0045] In this embodiment, when a filter body is installed on the filter port or filter hole, firstly, a filter screen is installed on the filter port or filter hole. The filter screen can be a fiber filter screen or a metal filter screen (such as stainless steel). To prevent clogging, the pore size of this filter screen can be relatively large. Then, a layer of filter cotton is installed on the inner or outer side of the filter screen. In this embodiment, the filter screen and the filter cotton together form the filter body described in this embodiment.

[0046] In this embodiment, the filter cotton has a smaller pore size than the filter screen, allowing it to filter finer dirt. It can be used in combination or separately. When used alone, the filter cotton can be removed and cleaned using only the underwater robot filter device 100. At this time, small stones, dead branches, and coarse debris settled at the bottom of the pool are collected within the filter device 100. When it floats to the surface, it can simultaneously clean floating leaves, plastic bags, fruit peels, etc., achieving a coarse filtration effect. After cleaning the pool bottom and / or the pool surface, the filter cotton is reinstalled for cleaning. Suspended matter, flocculent matter, and fine particulate matter in the pool are adsorbed onto the filter cotton. After cleaning, the filter cotton can be removed and washed. Its principle is similar to that of aquarium filters, but its disadvantage is that the filter cotton needs to be cleaned or replaced after each cleaning.

[0047] In this embodiment, filters with different mesh sizes can be installed on the first sidewall 110, the first side ear 112, the connecting wall, the second side ear 113, and the second sidewall 111. This allows for the collection of different types of waste in different areas without causing clogging. For example, if a filter with a larger mesh size is installed on the first sidewall 110, the first side ear 112, the second side ear 113, and the second sidewall 111, fine particles and flocculent matter will be collected at these locations. If a filter with a smaller mesh size is installed on the filter wall 114, water can still flow through the filter wall 114 even if the first sidewall 110, the first side ear 112, the second side ear 113, and the second sidewall 111 become clogged, without affecting the collection of waste at these locations.

[0048] like Figures 4-5As shown, the underwater robot filter device in the embodiment is applied to the underwater robot 120, which comprises an underwater robot body (hereinafter referred to as "body" or "underwater robot"). The bottom of the underwater robot 120 body is provided with a sewage suction port, and the side or / and upper part of the underwater robot 120 body is provided with a water outlet 123. The principle of cleaning of the underwater robot 120 is that the sewage is sucked from the bottom sewage suction port, and then the water is discharged from the water outlet 123 after the garbage is stored by the underwater robot filter device 100, so as to achieve the purpose of cleaning.

[0049] The lower part of the underwater robot 120 is provided with a walking mechanism, which is a walking wheel 121 or / and a walking track 122. In the underwater robot provided in the embodiment, the lower part of the underwater robot is provided with a walking wheel 121 on both sides, and a synchronous walking track 122 is also provided.

[0050] The walking track 122 can be provided with a separate drive, or can be a transmission track of the walking wheel 121 together with the walking wheel 121.

[0051] The underwater robot filter device 100 is arranged in the interior of the underwater robot 120 body and on the water flow channel between the sewage suction port and the water outlet 123. The sewage suction port and the water inlet 101 are in communication with each other.

[0052] In an embodiment, a second filter device 124 is further arranged on or in the body, and the second filter device 124 is arranged between the underwater robot filter device and the water outlet 123, for secondary filtering of the swimming pool water filtered by the underwater robot filter device, so as to achieve a further cleaning effect.

[0053] In an embodiment, the second filter device 124 is provided with a sewage suction wall, which is consistent with the special-shaped side wall of the filter device body and is mutually adhered. Specifically, the outer surface of the sewage suction wall is mutually adhered with the outer surface of the special-shaped side wall of the filter device body, and the effect of mutual adhesion is that the water flows out of the underwater robot filter device and immediately enters the second filter device 124, reducing the accumulation of dirty things in other structures inside the underwater robot 120. Alternatively, the second filter device 124 is at least partially arranged in the second filter cavity 102.

[0054] In an embodiment, the second filter device 124 is provided with a second filter body, which is one or a combination of a filter screen, filter cotton, filter paper, filter bag, activated carbon filter layer and particle filter layer.

[0055] Further, the filtering density on the second filter is coarser than the filtering density of the filter arranged on the filter port or filter hole, so as to further filter the finer particles.

[0056] In an embodiment, the second filtering device 124 is detachably arranged on the body of the underwater robot 120, and when the second filtering device 124 is dirty, it can be directly detached and cleaned, so that the structure is more flexible and the use is more convenient. The detachment mode in the embodiment is a common buckling mode, a pasting mode, a magnetic attraction mode and the like in the prior art, and all can achieve the effect of detachment and use, and the detachment mode will not be enumerated or described in detail in the embodiment.

[0057] Compared with the prior art, the underwater robot filtering device has the following beneficial effects:

[0058] The underwater robot filtering device and the underwater robot provided by the embodiment have the advantages of simple structure, convenient use, and the effect of collecting different garbage, and the filtering effect can be improved through the multi-layer filtering structure.

[0059] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the technical scheme of the utility model, and are not a limitation on the specific embodiments of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model claim should be included in the protection scope of the utility model claim.
