Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to an underwater robot filtering device and an underwater robot. Background Technique

[0002] Existing underwater cleaning robots (including swimming pools, fish ponds, etc.) mainly carry out underwater cleaning work in the following ways: washing the ground and walls, sucking water and dirt, filtering garbage, and discharging clear water. The robot is also equipped with a power system to move on the bottom and walls of the pool to achieve a comprehensive cleaning function. When the robot operates underwater, it mainly relies on rolling or fixed brushes to brush up the garbage and dust sticking to the ground or walls and bring them to the vicinity of the water inlet of the filtering device. Then, the water flow is driven by a water spraying motor (a water pumping motor) to be sucked into the filtering cavity. After the water flow passes through the filter screen, it is discharged from the nozzle, while the garbage and other dirt remain in the filtering device to achieve the cleaning function.

[0003] The filtering devices in the prior art usually adopt a single filter screen. A filter screen with a larger mesh number can filter finer garbage particles, but it is easily blocked and loses its filtering ability, resulting in the need for frequent manual cleaning. A filter screen with a smaller mesh number is not easily blocked, but its filtering effect is poor. The filtering device with a single filter screen cannot simultaneously meet the requirements of good filtering effect and not being easily blocked. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an underwater robot filtering device and an underwater robot, aiming to solve the problem that the existing filtering device with a single filter screen cannot simultaneously achieve good filtering effect and not being easily blocked.

[0005] To achieve the above purpose, the utility model provides an underwater robot filtering device, including:

[0006] A housing, one side of the housing is provided with a water inlet, and a filtering cavity is formed inside the housing; a plurality of filtering holes communicating with the filtering cavity are spaced on the outer wall of the housing, and a first filtering member is arranged at each filtering hole;

[0007] A filtering component, the filtering component includes a fixing member and a second filtering member. The second filtering member is installed on the fixing member and covers the outside of the housing. The fixing member is used to lock the second filtering member so that the second filtering member is in close contact with the housing. The mesh number of the second filtering member is greater than that of the first filtering member.

[0008] Preferably, the housing is of a columnar structure, the water inlet is arranged on the bottom surface of the housing, the second filtering member is a flexible filter screen, and the second filtering member covers the top surface and each side surface of the housing.

[0009] Preferably, the fixing element is arranged on a side of the second filter element close to the bottom surface of the shell, and is used to fix the second filter element to the bottom wall of the shell of the underwater robot so as to make the second filter element close to the shell.

[0010] Preferably, the fixing element is detachably connected to the second filter element and the bottom wall of the housing of the underwater robot.

[0011] Preferably, the fixing member is a pressure rod, which is arranged around the outer circumference of the shell and presses the second filter elements in each direction of the outer circumference of the shell onto the bottom wall of the shell of the underwater robot.

[0012] Preferably, the fixing member is a Velcro, a hook or a screw, and there are multiple fixing members, and the multiple fixing members are arranged at intervals on the outer periphery of the shell.

[0013] Preferably, one side of the shell is open, and a water inlet structure is provided at the opening. The water inlet structure is a cylindrical structure with openings at both ends. The openings at both ends of the water inlet structure are an upper opening and a lower opening respectively. A check piece is provided at the upper opening, and the check piece is used to prevent water in the filter chamber from flowing out of the upper opening. The lower opening forms the water inlet.

[0014] Preferably, a handle is provided on a side of the shell facing away from the water inlet, and an avoidance hole is formed on the second filter element corresponding to the handle.

[0015] The utility model also provides an underwater robot, and the underwater robot is applied with the underwater robot filtering device.

[0016] In the technical solution of the utility model, a filter cavity is formed in the shell, and a plurality of filter holes connected to the filter cavity are arranged on the outer wall of the shell, and a first filter element is arranged at each filter hole, so that the sewage entering the filter cavity from the water inlet is first filtered by the first filter element, and a second filter element is arranged on the outer side of the shell and is close to the shell. Since the mesh number of the second filter element is greater than the mesh number of the first filter element, the first filter element first filters the larger particles in the sewage, and the remaining sewage after filtering is filtered through the second filter element for more fine filtering. On the one hand, the filtering effect can be improved by the second filter element, and on the other hand, the larger particle impurities in the remaining sewage after filtering by the first filter element have been left in the filter cavity, which is less likely to clog the second filter element, so that the filtering device has both the advantages of good filtering effect and not easy to clog. In addition, the second filter element is closely attached to the shell through the fixing element, so that the second filter element will not fall off during use, ensuring the filtering effect.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] Please refer to Figure 1 and Figure 2 , the present utility model provides an underwater robot filtering device 100, which includes a housing 1 and a filtering component 2. An inlet 11 is provided on one side of the housing 1, and a filtering chamber is formed inside the housing 1; a plurality of filtering holes 12 communicating with the filtering chamber are spaced on the outer wall of the housing 1, and a first filtering member 13 is provided at each filtering hole 12; the filtering component 2 includes a fixing member 21 and a second filtering member 22. The second filtering member 22 is installed on the fixing member 21 and covers the outside of the housing 1. The fixing member 21 is used to lock the second filtering member 22 so that the second filtering member 22 is in close contact with the housing 1, and the mesh number of the second filtering member 22 is greater than that of the first filtering member 13.

[0029] In the technical solution of the present utility model, a filter chamber is formed inside the housing 1, and a plurality of filter holes 12 communicating with the filter chamber are provided on the outer wall of the housing 1, and a first filter element 13 is provided at each filter hole 12, so that the sewage entering the filter chamber from the water inlet 11 is first preliminarily filtered by the first filter element 13. A second filter element 22 is provided outside the housing 1 and is in close contact with the housing 1. Since the mesh number of the second filter element 22 is greater than that of the first filter element 13, after the first filter element 13 filters out the larger particles in the sewage, the remaining filtered sewage is further finely filtered by the second filter element 22. On the one hand, the filtering effect can be improved by the second filter element 22. On the other hand, the larger particle impurities in the remaining sewage after being filtered by the first filter element 13 have remained in the filter chamber and are less likely to block the second filter element 22, so that the filtering device has both good filtering effect and is not easily blocked. Moreover, the second filter element 22 is tightly attached to the housing 1 by the fixing member 21, so that the second filter element 22 will not fall off during use and the filtering effect is ensured.

[0030] In one embodiment, the housing 1 is of a columnar structure, a water inlet 11 is provided on the bottom surface of the housing 1, and the second filter element 22 is a flexible filter mesh that covers the top surface and each side surface of the housing 1. It can be understood that when the housing 1 is of a columnar structure, it has a top surface and side surfaces, and the second filter element 22 covers the top surface and each side surface of the housing 1, which can increase the coverage area of the second filter element 22 and prevent some of the sewage that has only been filtered by the first filter element 13 from flowing out of the area not covered by the second filter element 22, so that all the filter holes 12 are covered by the second filter element 22 and the overall filtering effect is improved.

[0031] In one embodiment, the fixing member 21 is provided on the side of the second filter element 22 close to the bottom surface of the housing 1 and is used to fix the second filter element 22 to the bottom wall of the outer shell of the underwater robot to tightly attach the second filter element 22 to the housing 1. It can be understood that the underwater robot usually sucks sewage from the bottom, so the filtering device is also arranged at the bottom of the outer shell of the underwater robot. By arranging the fixing member 21 on the side of the second filter element 22 close to the bottom surface of the housing 1, on the one hand, the second filter element 22 can be pressed against the outside of the housing 1 by the pressing effect of the fixing member 21, so that there is no need to set a fixing structure for fixing the second filter element 22 at the top of the housing 1. On the other hand, the volume of the fixing member 21 can be reduced, and the fixing member 21 can be directly in contact with the bottom wall of the outer shell of the underwater robot, optimizing the internal space planning of the underwater robot.

[0032] Furthermore, the fixing member 21 is detachably connected to the second filter member 22 and the bottom wall of the housing of the underwater robot. The detachable design makes it very simple to replace the second filter member 22. There is no need to disassemble the entire device or perform complex operations. Just loosen the fixing member 21 to remove and replace the filter member. This is very convenient for regular maintenance and replacement of the filter member. It should be noted that the second filter member 22 needs to be replaced not only when it is blocked by impurities, particles or biological attachments after long-term use, but also when it is necessary to replace the mesh number of the second filter member 22 in response to different working scenarios. Therefore, making the second filter member 22 detachable from the fixing member 21 can improve the replacement efficiency of the second filter member 22 and enhance the convenience.

[0033] It should be noted that since the fixing member 21 is detachably connected to the second filter member 22 and the bottom wall of the housing of the underwater robot, the second filter member 22 and the fixing member 21 can also be removed when necessary, and only the first filter member 13 is used for the filtering operation, thereby saving energy consumption and wear of the second filter member 22.

[0034] In a specific embodiment, the fixing member 21 is a pressure bar. The fixing member 21 is arranged around the outer periphery of the housing 1 and presses the second filter members 22 in all directions on the outer periphery of the housing 1 against the bottom wall of the housing of the underwater robot. The pressure bar surrounding the outer periphery of the housing 1 can uniformly apply pressure in all directions of the housing 1 to ensure that the second filter member 22 is closely attached to the housing 1 on the entire contact surface. At the same time, by pressing the second filter member 22 with the pressure bar, there is no need for additional disassembly and assembly steps. Just pick up the pressure bar to replace the second filter member 22, which improves the convenience.

[0035] Specifically, the pressure bar can be a pressure bar with a relatively large weight and density, which presses down the second filter member by its own gravity, or a magnetic pressure bar, by setting a magnetic attachment on the pressure bar to adsorb it to the metal housing of the underwater robot; or by setting a magnetic attachment on the bottom shell of the underwater robot to adsorb the metal pressure bar; or magnetic attachments can be provided on both the bottom shell of the underwater robot and the pressure bar for cooperative adsorption.

[0036] In another specific embodiment, the fixing member 21 is a sticky fastener, a hanging fastener or a screw. The number of the fixing members 21 is multiple, and the multiple fixing members 21 are arranged at intervals on the outer periphery of the housing 1. Compared with the pressing block, when the fixing member 21 is a sticky fastener, a hanging fastener or a screw, the fixing of the second filter member 22 is more stable, providing stronger connection stability. At the same time, the disassembly and assembly difficulty increases little, and simple disassembly and assembly can still be carried out without too complicated a replacement process.

[0037] In one embodiment, one side of the shell 1 is open, and a water inlet structure 3 is provided at the opening. The water inlet structure 3 is a cylindrical structure with openings at both ends. The openings at both ends of the water inlet structure 3 are an upper opening and a lower opening, respectively. A check piece is provided at the upper opening, and the check piece is used to prevent water in the filter cavity from flowing out from the upper opening. The lower opening forms a water inlet 11. Since the check piece is provided at the upper opening, the check piece will only open the upper opening when water flows from the lower opening to the upper opening, so that water carrying garbage enters the inner cavity of the shell 1 through the upper opening. When the water in the inner cavity flows to the upper opening, the check piece closes the upper opening to prevent the water carrying garbage from flowing back, thereby improving the cleaning effect, and the cleaning can be completed in one time, which improves the cleaning efficiency.

[0038] In one embodiment, a handle 4 is provided on the side of the housing 1 facing away from the water inlet 11, and a relief hole is formed in the second filter element 22 corresponding to the handle 4. The handle 4 enables the operator to easily grab and remove the filter device, and when the filter cavity of the filter device is filled with garbage and needs to be cleaned, the entire device can be quickly removed from the underwater robot, reducing the difficulty of operation.

[0039] The utility model also provides an underwater robot, which is applied with the underwater robot filtering device 100. The specific structure of the underwater robot filtering device 100 refers to the above embodiment. Since the underwater robot adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0040] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
