Description

Technical Field

[0001] This application relates to the technical field of cleaning robots, and particularly to an underwater cleaning robot. Background Art

[0002] An underwater cleaning robot is a robot capable of performing underwater cleaning tasks. For example, it can clean the bottom and walls of pools such as swimming pools and fish ponds.

[0003] In the underwater cleaning robots in the related art, buoyancy blocks are provided. During installation, the buoyancy blocks are first placed in a buoyancy box, and then the buoyancy box is fixed to the housing of the cleaning robot by screwing, and the installation process is relatively cumbersome. Summary of the Utility Model

[0004] This application provides an underwater cleaning robot, aiming to simplify the installation process of the buoyancy blocks to improve the installation efficiency.

[0005] The specific technical solution is as follows:

[0006] An embodiment of this application provides an underwater cleaning robot, which includes: a housing; a floating structure, the floating structure includes one or more buoyancy blocks connected together, and the floating structure is detachably fixed to the housing.

[0007] In the underwater cleaning robot in the embodiment of this application, the floating structure can be installed on the housing. Moreover, the floating structure includes one or more buoyancy blocks connected together, and the floating structure is detachably fixed to the housing. That is to say, the floating structure composed of buoyancy blocks is directly installed on the housing of the cleaning robot. Compared with the method in the related art of placing the buoyancy blocks in a buoyancy box and then fixing the buoyancy box to the housing, the installation process in the embodiment of this application is relatively simple and the operation is also more convenient, which is beneficial to improving the installation efficiency of the buoyancy blocks.

[0008] In some embodiments of this application, the floating structure is fixed to the housing by pasting; when the floating structure includes multiple buoyancy blocks, any two adjacent buoyancy blocks are connected by pasting. Fixing the floating structure to the housing by pasting, or connecting multiple buoyancy blocks by pasting, can be more convenient in operation.

[0009] In some embodiments of this application, the lower surface of the buoyancy block is provided with adhesive. Thus, the convenience of installing the buoyancy block can be further improved.

[0010] In some embodiments of the present application, the number of the buoyancy blocks is one, and the buoyancy block is connected to the housing through the adhesive. When only one buoyancy block needs to be installed on the underwater cleaning robot, the buoyancy block can be directly pasted on the housing through the adhesive on it. The installation process is relatively simple and the operation is relatively convenient.

[0011] In some embodiments of the present application, the number of the buoyancy blocks is multiple, and the multiple buoyancy blocks are stacked. The buoyancy block at the lowermost position is connected to the housing through the adhesive, and the remaining buoyancy blocks are connected to the adjacent buoyancy blocks through the adhesive. When multiple buoyancy blocks need to be installed on the underwater cleaning robot, one of the buoyancy blocks can be first pasted on the housing through its own adhesive, and then multiple buoyancy blocks are stacked in sequence. Each of the subsequently installed buoyancy blocks is pasted on the previously installed buoyancy block through the adhesive. It can be seen that for the case of installing multiple buoyancy blocks, the installation process is still relatively simple and the operation is relatively convenient.

[0012] In some embodiments of the present application, the housing is formed with a positioning groove, and the floating body structure is arranged in the positioning groove. The positioning groove provides a dedicated installation space for the floating body structure. The floating body structure is installed in the positioning groove, which is beneficial to avoiding interference between the floating body structure and other structures of the cleaning robot. In addition, the installation position of the floating body structure in the cleaning robot will affect the position of the center of buoyancy of the cleaning robot. Therefore, by providing the positioning groove for installing the floating body structure, it is beneficial to improve the position accuracy of the floating body structure, and thus beneficial to improving the accuracy of the position of the center of buoyancy of the cleaning robot.

[0013] In some embodiments of the present application, the positioning groove includes a positioning groove bottom wall and a positioning groove side wall, and the positioning groove side wall is perpendicular to the positioning groove bottom wall; the floating body structure is fixed to the positioning groove bottom wall in a detachable manner; the side of the buoyancy block abuts against the positioning groove side wall. The positioning groove bottom wall provides a pasting basis for the floating body structure, and the wall surface of the positioning groove bottom wall is a plane, so as to ensure that the floating body structure remains relatively flat after pasting. The positioning groove side wall provides a positioning function. By making the side of the buoyancy block abut against the positioning groove side wall, the pasted buoyancy block can extend along a preset direction, so as to improve the installation accuracy of the buoyancy block.

[0014] In some embodiments of the present application, the positioning groove side wall extends along a first direction, and the first direction is perpendicular to the traveling direction of the underwater cleaning robot; the buoyancy block is a long strip structure, and the long side of the long strip structure extends along the first direction. In this way, it is beneficial to make the buoyancy received by the underwater cleaning robot be relatively evenly distributed in the first direction, so as to avoid the movement tendency of the underwater cleaning robot to roll over.

[0015] In some embodiments of the present application, the cleaning robot further includes an upper cover body, which is connected to the housing, and the upper cover body and the housing jointly define a receiving cavity for receiving devices; a connecting post is provided on the side wall of the positioning groove, and the upper cover body is connected to the connecting post by a screw; the connecting post is located at the end position of the side wall of the positioning groove in the first direction; an avoidance groove is provided at the end of the buoyancy block along the first direction, and the avoidance groove is used to avoid the connecting post. The avoidance groove can avoid the connecting post, so as to prevent interference between the buoyancy block and the connecting post.

[0016] In some embodiments of the present application, the underwater cleaning robot further includes: a traveling mechanism, which is arranged on both sides of the housing along the first direction; a roller, which is arranged at the front end of the housing; wherein, the floating body structure is located behind the roller and is arranged adjacent to the roller. The floating body structure is arranged behind the roller and adjacent to it. When the underwater cleaning robot needs to climb from the bottom of the pool to the pool wall, the water pressure at the water outlet can be reduced. After the water pressure is reduced, since the floating body structure is arranged at the front of the underwater cleaning robot, the front of the underwater cleaning robot has a tendency to float. At this time, both the traveling mechanism and the roller are in working state. When the underwater cleaning robot moves forward and contacts the pool wall, under the action of the rotating roller, and in cooperation with the tendency of the front of the underwater cleaning robot to float, the underwater cleaning robot can climb onto the pool wall more easily.

[0017] In some embodiments of the present application, a part of the structure of the roller protrudes forward from the housing; the roller includes a connecting cylinder and a plurality of fins arranged on the surface of the connecting cylinder. With such an arrangement, when the underwater cleaning robot climbs from the bottom of the pool to the pool wall, the roller contacts the pool wall first. In this way, under the action of the rotating roller, the front part of the underwater cleaning robot can rise along the pool wall. When the roller rotates, the fins can increase the friction between the roller and the wall surface, so that the bottom of the pool or the pool wall can be cleaned more effectively, or it is more conducive to using the force of the roller to enable the underwater cleaning robot to climb onto the pool wall.

[0033] An underwater cleaning robot is a robot that can perform underwater cleaning tasks. For example, it can clean the bottom and walls of pools such as swimming pools and fish ponds.

[0034] In the underwater cleaning robots in the related art, buoyancy blocks are provided. During installation, the buoyancy blocks are first placed in a buoyancy box, and then the buoyancy box is fixed to the housing of the cleaning robot by screwing, and the installation process is relatively cumbersome.

[0035] Based on this, the embodiments of the present application provide an underwater cleaning robot, aiming to simplify the installation process of the buoyancy blocks to improve the installation efficiency.

[0036] As Figure 1 , Figure 2 and Figure 3 shown, the underwater cleaning robot 1 in the embodiments of the present application includes a housing 10 and a floating structure 20. The floating structure 20 includes one or more buoyancy blocks 21 connected together, and the floating structure 20 is detachably fixed to the housing 10.

[0037] In the underwater cleaning robot 1 in the embodiments of the present application, the floating structure 20 can be installed on the housing 10, and the floating structure 20 includes one or more buoyancy blocks 21 connected together, and the floating structure 20 is detachably fixed to the housing 10, that is, the floating structure 20 composed of the buoyancy blocks 21 is directly installed on the housing 10 of the cleaning robot 1. Compared with the method in the related art of placing the buoyancy blocks 21 in a buoyancy box and then fixing the buoyancy box to the housing 10, the installation process in the embodiments of the present application is relatively simple and the operation is also relatively convenient, which is beneficial to improving the installation efficiency of the buoyancy blocks 21.

[0038] In some embodiments, the floating structure 20 is fixed to the housing 10 by pasting. When the floating structure 20 includes a plurality of buoyancy blocks 21, any two adjacent buoyancy blocks 21 are connected by pasting. Fixing the floating structure to the housing by pasting, or connecting a plurality of buoyancy blocks together by pasting, can be more convenient in operation. In addition, when it is necessary to remove the floating structure 20, the floating structure 20 can be separated from the housing 10 by means of an external force.

[0039] Further, the surface of the housing 10 for pasting the floating body structure 20 may adopt a smooth surface, so that the operation difficulty when disassembling the floating body structure 20 can be reduced, and the floating body structure 20 can be separated from the housing 10 more smoothly.

[0040] In some other embodiments, the floating body structure 20 is fixed to the housing 10 by screws, whereby the floating body structure 20 is detachable relative to the housing 10.

[0041] In some embodiments, as Figure 2 、 Figure 3 shown, an adhesive tape 22 is provided on the lower surface of the buoyancy block 21. By providing the adhesive tape 22, the buoyancy block 21 has adhesiveness after leaving the factory. When the buoyancy block 21 is in use, the release paper covering the adhesive tape 22 can be torn off for pasting. Thus, the convenience of installing the buoyancy block 21 can be further improved.

[0042] In one of the embodiments, as Figure 1 、 Figure 2 shown, the number of buoyancy blocks 21 is one, and the buoyancy block 21 is connected to the housing 10 through the adhesive tape 22. That is to say, when the underwater cleaning robot 1 only needs to install one buoyancy block 21, the buoyancy block 21 can be directly pasted on the housing 10 through the adhesive tape 22 on it. The installation process is relatively simple and the operation is relatively convenient.

[0043] In another embodiment, as Figure 3 shown, the number of buoyancy blocks 21 is multiple, and the multiple buoyancy blocks 21 are stacked. The lowermost buoyancy block 21 is connected to the housing 10 through the adhesive tape 22, and the remaining buoyancy blocks 21 are connected to the adjacent buoyancy blocks 21 through the adhesive tape 22. That is to say, when the underwater cleaning robot 1 needs to install multiple buoyancy blocks 21, one of the buoyancy blocks 21 can be pasted on the housing 10 through its own adhesive tape 22 first, and then multiple buoyancy blocks 21 are stacked in sequence. Each of the subsequently installed buoyancy blocks 21 is pasted on the previously installed buoyancy block 21 through the adhesive tape 22. It can be seen that for the case of installing multiple buoyancy blocks 21, the installation process is still relatively simple and the operation is also relatively convenient.

[0044] In some embodiments, as Figure 1As shown, the housing 10 is formed with a positioning groove 11, and the floating body structure 20 is disposed in the positioning groove 11. The positioning groove 11 provides a dedicated installation space for the floating body structure 20. Installing the floating body structure 20 in the positioning groove 11 helps to avoid interference between the floating body structure 20 and other structures of the cleaning robot 1. In addition, the installation position of the floating body structure 20 in the cleaning robot 1 affects the position of the center of buoyancy of the cleaning robot 1. Therefore, by providing the positioning groove 11 for installing the floating body structure 20, it is beneficial to improve the position accuracy of the floating body structure 20, and thus beneficial to improve the accuracy of the center of buoyancy position of the cleaning robot 1.

[0045] In some embodiments, as Figure 1 shown, the positioning groove 11 includes a positioning groove bottom wall 1101 and a positioning groove side wall 1102. The positioning groove side wall 1102 is perpendicular to the positioning groove bottom wall 1101. The floating body structure 20 is detachably fixed to the positioning groove bottom wall 1101, and the side of the buoyancy block 21 abuts against the positioning groove side wall 1102.

[0046] It can be understood that the positioning groove bottom wall 1101 provides an installation foundation for the floating body structure 20, and the wall surface of the positioning groove bottom wall 1101 is a plane, which can ensure that the floating body structure 20 remains relatively flat after installation. The positioning groove side wall 1102 provides a positioning function. By making the side of the buoyancy block 21 abut against the positioning groove side wall 1102, the detachable buoyancy block 21 can extend along a preset direction (the extending direction of the positioning groove side wall 1102), so as to improve the installation accuracy of the buoyancy block 21. In addition, when the number of buoyancy blocks 21 is multiple, it can also ensure that the multiple buoyancy blocks 21 are flush with each other.

[0047] In some embodiments, the positioning groove side wall 1102 extends along a first direction, and the first direction is perpendicular to the traveling direction of the underwater cleaning robot 1. The buoyancy block 21 is a strip-shaped structure, and the length of the strip-shaped structure extends along the first direction.

[0048] It can be understood that the first direction is perpendicular to the traveling direction of the underwater cleaning robot 1. That is to say, the first direction can be understood as the left-right direction of the underwater cleaning robot 1. The positioning groove side wall 1102 extends along the first direction, which enables the strip-shaped buoyancy block 21 to extend relatively precisely along the first direction after installation. In this way, it is beneficial to make the buoyancy received by the underwater cleaning robot 1 be evenly distributed in the first direction, thereby avoiding the tendency of the underwater cleaning robot 1 to roll over.

[0049] In some embodiments, the underwater cleaning robot 1 further includes an upper cover body (not shown in the figure). The upper cover body is connected to the housing 10, and the upper cover body and the housing 10 jointly define a receiving cavity for accommodating devices. A connecting post 1103 is provided on the side wall 1102 of the positioning groove. The upper cover body is connected to the connecting post 1103 by screws, and the connecting post 1103 is located at the end position of the side wall 1102 of the positioning groove in the first direction. An avoidance groove 211 is provided at the end of the buoyancy block 21 in the first direction, and the avoidance groove 211 is used to avoid the connecting post 1103.

[0050] In this embodiment, the upper cover body is connected to the housing 10, and the upper cover body and the housing 10 jointly define a receiving cavity, which can accommodate various functional devices of the underwater cleaning robot 1. For example, a power unit, a control unit, a filtering unit, etc. Specifically, a connecting post 1103 is provided on the side wall 1102 of the positioning groove, and the upper cover body is connected to the connecting post 1103 by screws, whereby the connection between the upper cover body and the housing 10 can be realized. On this basis, an avoidance groove 211 is provided on the buoyancy block 21, and the avoidance groove 211 can avoid the connecting post 1103, thereby preventing interference between the buoyancy block 21 and the connecting post 1103.

[0051] In some embodiments, as Figure 1 shown, the underwater cleaning robot 1 further includes a traveling mechanism 30 and a roller 40. The traveling mechanism 30 is disposed on both sides of the housing 10 in the first direction, and the roller 40 is disposed at the front end of the housing 10; wherein, the floating body structure 20 is located behind the roller 40 and is disposed adjacent to the roller 40.

[0052] Generally, the underwater cleaning robot 1 also has a water suction port and a water outlet. The underwater cleaning robot 1 is internally provided with a water flow driving device (such as a water pump). Among them, the water outlet direction of the water outlet is perpendicular to the traveling direction of the underwater cleaning robot 1. By increasing the water pressure at the water outlet, the reaction force of the water flowing out of the water outlet can be increased. Under the action of this reaction force, the underwater cleaning robot 1 can closely adhere to the bottom or wall of the pool. When the underwater cleaning robot 1 closely adheres to the bottom or wall of the pool, the traveling mechanism 30 can be used to drive the underwater cleaning robot 1 to walk along the bottom of the pool or crawl along the wall of the pool.

[0053] The drum 40 has multiple functions. The primary function of the drum 40 is to be able to perform cleaning work. When the drum 40 is working, it can contact the bottom or the wall of the pool. Through the rotation of the drum 40, the surface of the bottom or the wall of the pool can be cleaned. Another function of the drum 40 is to assist in climbing the wall. Specifically, the floating structure 20 is arranged behind and adjacent to the drum 40. When the underwater cleaning robot 1 needs to climb from the bottom of the pool to the wall, the water pressure at the water outlet can be reduced. After the water pressure is reduced, since the floating structure 20 is arranged at the front of the underwater cleaning robot 1, the front part of the underwater cleaning robot 1 has a tendency to float upward. At this time, both the traveling mechanism 30 and the drum 40 are in working states. When the underwater cleaning robot 1 moves forward to contact the wall, under the action of the rotating drum 40 and in cooperation with the upward floating tendency of the front part of the underwater cleaning robot 1, the underwater cleaning robot 1 can climb the wall more easily. After the underwater cleaning robot 1 completely climbs the wall, increasing the water pressure at the water outlet can make the underwater cleaning robot 1 keep in close contact with the wall. Then, using the traveling mechanism 30, the underwater cleaning robot 1 can crawl on the wall.

[0054] Furthermore, the traveling mechanism 30 can be a roller or a crawler. When the traveling mechanism 30 is a roller, the number of rollers can be four, and two rollers are arranged on each side of the housing 10. When the traveling mechanism 30 is a crawler, the number of crawlers can be two, and one crawler is arranged on each side of the housing 10.

[0055] In some embodiments, a part of the structure of the drum 40 protrudes forward from the housing 10. With such an arrangement, during the process of the underwater cleaning robot 1 climbing from the bottom of the pool to the wall, the drum 40 contacts the wall first. In this way, under the action of the rotating drum 40, the front part of the underwater cleaning robot 1 can rise along the wall.

[0056] Furthermore, the drum 40 includes a connecting cylinder 401 and a plurality of fins 402 arranged on the surface of the connecting cylinder 401. When the drum 40 rotates, the fins 402 can increase the friction between the drum 40 and the wall surface, so as to clean the bottom or the wall of the pool more effectively, or it is more beneficial to rely on the acting force of the drum 40 to enable the underwater cleaning robot 1 to climb the wall.

[0057] In some embodiments, the buoyancy block 21 is a pressed EVA buoyancy block. Herein, EVA refers to ethylene-vinyl acetate copolymer, which is a polymer prepared by copolymerization of ethylene and vinyl acetate. It has good wear resistance and can also resist sunlight, oxidation, and acid-base erosion. In addition, the buoyancy block 21 can be pressed from EVA material, and can be mass-produced, which is beneficial to improving the production efficiency of the buoyancy block 21.

[0058] The above content is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
