Description

Technical Field

[0001] This utility model relates to the field of intelligent cleaning equipment technology, specifically to an underwater cleaning robot. Background Technology

[0002] In the field of pool cleaning, underwater cleaning robots have gradually gained popularity among users in recent years as a professional pool cleaning equipment, and their importance is becoming increasingly apparent. Especially in private and public pools, these underwater cleaning robots can save labor costs and perform repetitive daily tasks. Therefore, they have gradually become the preferred robots for underwater pool cleaning.

[0003] However, existing underwater cleaning robots are all operating in underwater environments. During walking and climbing, they are affected by the buoyancy of the water and the impact of the water jets. This causes the underwater cleaning robots to be unstable during walking or climbing, which can easily lead to problems such as deviations in walking direction and angle, deviations in angle when climbing, and insufficient adhesion.

[0004] Therefore, how to make underwater cleaning robots walk more smoothly, maintain the correct angle, and have better adhesion is a technical problem that the industry urgently needs to solve. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art and provide an underwater cleaning robot to solve problems such as unstable walking, angular deviation, and insufficient adhesion of existing underwater cleaning robots.

[0006] The technical solution adopted by this utility model is to provide an underwater cleaning robot, which includes an underwater cleaning robot body, a filter device inside the underwater cleaning robot body, a water inlet connected to the filter device at the bottom of the underwater cleaning robot body, and a water outlet at the side and / or top of the underwater cleaning robot body; when working, the liquid in the pool enters from the water inlet and flows out from the water outlet, and the garbage mixed in the liquid stays in the filter device, thereby achieving the cleaning of the pool.

[0007] The main body is equipped with wheels on both sides, which provide the walking power for the underwater cleaning robot; the main body is also equipped with a control circuit and a drive motor, which is connected to the wheels and makes the wheels rotate.

[0008] The front end of the main body is equipped with a roller brush, which brings water and debris into the water inlet located at the bottom of the main body during cleaning. The surface of the roller brush is equipped with several silicone scrapers, which can effectively clean the bottom wall of the swimming pool.

[0009] A tail fin is provided at the rear end or upper rear end of the main body. The tail fin includes at least two connecting bodies connected to the main body, and wing bodies interconnected with the connecting bodies. There is a gap between the wing bodies and the main body. During operation, water can flow through the gap and be subjected to the horizontal force of the wing bodies, thereby making the underwater cleaning robot more stable in the water.

[0010] Furthermore, the wing body includes a first wingplate and a second wingplate arranged at an upper and lower interval. The length, width, and angle of the first wingplate and the second wingplate are substantially the same.

[0011] Furthermore, the upper surfaces of the first and second wing plates are flat. The flat surface minimizes water resistance when the underwater cleaning robot moves horizontally. Simultaneously, when there is turbulent water, the flat surface effectively suppresses the turbulence, allowing the underwater cleaning robot to quickly reach a level surface, thus achieving stable operation and preventing angular deviations during movement. This ensures the underwater cleaning robot can remain firmly on the bottom surface with strong adhesion.

[0012] Furthermore, the first wing plate and the second wing plate are arranged in parallel. The distance between the first wing plate and the second wing plate is 1cm-5cm, preferably between 1.5cm-2cm, for best control of stable water flow.

[0013] Furthermore, the middle portion of the first wing plate is bent inward to form an inclined first guide plate; the middle portion of the second wing plate is bent inward to form an inclined second guide plate. The guide plates are positioned in the middle and at the opposite angle to the wing plates, making the water flow smoother when turbulent water passes through, thus preventing angular deviations during travel.

[0014] Furthermore, the length of the first deflector is 1 / 3 to 1 / 2 of the length of the first wing; the length of the second deflector is 1 / 3 to 1 / 2 of the length of the second wing.

[0015] Furthermore, the angle between the first guide vane and the first wing is 45°–95°; the angle between the second guide vane and the second wing is 45°–95°.

[0016] Furthermore, the angle between the first wing plate, the second wing plate and the bottom horizontal plane of the body is 15°–45°.

[0017] Furthermore, the connector is fixed to the main body via a connecting base. Specifically, the connecting base is provided at the end of the connector, and the connecting base extends laterally in a plate shape around the end of the connector. Mounting holes are provided in the circumferential direction of the extending connecting base, and screws are passed through the mounting holes to fix it to the main body.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model provides an underwater cleaning robot, in which a tail fin is provided at the rear end or upper rear end of the main body. The tail fin includes at least two connecting bodies connected to the main body, and wing bodies interconnected with the connecting bodies, with a gap between the wing bodies and the main body. During operation, water can flow through the gap and be subjected to the horizontal force of the wing bodies, thus making the underwater cleaning robot more stable in the water. Furthermore, the addition of structures such as winglets and guide vanes further enhances the stability of the underwater cleaning robot, preventing angular deviations during movement and allowing the robot to remain firmly on the bottom surface with strong adhesion.

[0027] 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.

[0028] Example 1

[0029] like Figure 1-4 As shown, this embodiment provides an underwater cleaning robot, particularly an underwater cleaning robot suitable for cleaning swimming pools. It includes an underwater cleaning robot body 1, with a filter device inside. The bottom of the underwater cleaning robot body 1 has a water inlet 2 communicating with the filter device, and the side and / or top of the underwater cleaning robot body 1 has a water outlet 3. In this embodiment, the water outlet 3 is preferably located at the top. During operation, liquid in the pool enters through the water inlet 2 and flows out through the water outlet 3. Debris mixed in the liquid remains inside the filter device, thereby cleaning the pool.

[0030] The main body 1 has wheels 4 on both sides, which provide the underwater cleaning robot with the power to move. The main body 1 also contains a control circuit and a drive motor (not shown in the figure, as this is not a key feature of the invention). The drive motor is connected to the wheels 4 and causes them to rotate. The drive motor and control circuit are the same as those used in conventional underwater cleaning robots, and will not be described in detail in this embodiment.

[0031] The front end of the main body 1 is provided with a roller brush 5, which brings water and debris into the water inlet 2 located at the bottom of the main body 1 during cleaning. The surface of the roller brush 5 is provided with several silicone scrapers, which can effectively clean the bottom wall of the swimming pool.

[0032] A tail fin 6 is provided at the rear end or upper rear end of the main body 1. The tail fin 6 includes at least two connecting bodies 61 connected to the main body 1. In this embodiment, there are two connecting bodies 61, which are respectively located on the left and right sides of the upper rear end of the main body 1, with their angles slightly upward. A wing body is also connected to the connecting bodies 61, and there is a gap between the wing body and the main body 1. During operation, water can flow through the gap and be subjected to the horizontal force of the wing body, thereby making the underwater cleaning robot more stable in the water.

[0033] In this embodiment, the horizontal height of the wing body is basically the same as the horizontal height of the upper part of the main body 1.

[0034] like Figure 5 , 6 As shown, in one embodiment, the wing includes a first wingplate 62 and a second wingplate 63 arranged vertically at intervals. The length, width, and angle of the first wingplate 62 and the second wingplate 63 are substantially the same.

[0035] In one embodiment, the upper surfaces of the first wing plate 62 and the second wing plate 63 are planar. The planar surface minimizes water resistance when the underwater cleaning robot moves horizontally. At the same time, when there is turbulent water, the planar surface can effectively suppress the turbulence, allowing the underwater cleaning robot to quickly reach a calm water area, thereby achieving stable operation of the underwater cleaning robot.

[0036] like Figure 5 , 6 As shown, in one embodiment, the first wing plate 62 and the second wing plate 63 are arranged in parallel. The distance between the first wing plate 62 and the second wing plate 63 is 1cm-5cm. In this embodiment, it is preferably between 1.5cm-2cm, which is best for controlling the water flow smoothly.

[0037] like Figure 5 , 6 As shown, in one embodiment, the middle portion of the first wing plate 62 is bent inward to form an inclined first guide plate 64; the middle portion of the second wing plate is bent inward to form an inclined second guide plate 65. The guide plates are positioned in the middle and at an angle opposite to that of the wing plates, making the water flow smoother when turbulent water passes through them.

[0038] In one embodiment, the length of the first guide vane 64 is 1 / 3 to 1 / 2 of the length of the first wing 62; the length of the second guide vane 65 is 1 / 3 to 1 / 2 of the length of the second wing 63. In this embodiment, the first guide vane 64 and the second guide vane 65 are respectively 1 / 3 of the length of the first wing 62 and the second wing 63.

[0039] In one embodiment, the angle between the first guide vane 64 and the first wing 62 is 45°–95°; the angle between the second guide vane 65 and the second wing 63 is 45°–95°.

[0040] In this embodiment, the angle between the first guide vane 64 and the first wing 62 is 90°; the angle between the second guide vane 65 and the second wing 63 is 90°. The effect is optimal when they form right angles.

[0041] In one embodiment, the angle between the first wing plate 62, the second wing plate 63 and the bottom horizontal plane of the body 1 is 15°–45°.

[0042] In this embodiment, the angle between the first wing plate 62, the second wing plate 63 and the bottom horizontal plane of the body 1 is 15°. If the first wing plate 62 and the second wing plate 63 are directly horizontal with the bottom, the turbulence effect is not ideal. Therefore, a certain angle is required. However, if the angle is too large, the effect is also not ideal. Therefore, 15° is preferred in this embodiment.

[0043] In one embodiment, the connector 61 is fixed to the body 1 via a connecting base 66.

[0044] Specifically, the end of the connector 61 is provided with the connecting base 66. The connecting base 66 extends laterally in a plate shape around the end of the connector 61. The connecting base 66 has mounting holes in the circumferential direction of the extension, and screws pass through the mounting holes to fix it to the body 1.

[0045] In this embodiment, the connecting base 66 can be fixed to the body 1 without screws. Instead, a fixing adhesive is provided at the bottom of the connecting base 66, and the fixing adhesive is bonded to the body 1 to achieve the same technical effect.

[0046] In addition to the aforementioned screw fixing and adhesive fixing, the connecting base 66 and the main body 1 can also be fixed by conventional mechanical methods such as ultrasonic fixing, which will not be listed one by one in this embodiment.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
