Description

Technical Field

[0001] This utility model belongs to the technical field of water surface cleaning equipment, and relates to an anti-tangling roller brush mechanism. Background Technology

[0002] A water surface cleaning robot is an automatic cleaning device that collects floating debris on the water surface. A through-channel is located beneath the robot, extending from the front to the rear. A drive motor and impeller are located at the rear of the through-channel. The drive motor drives the impeller, propelling the robot forward. During its movement, the robot draws water in from the front and discharges it from the rear. A collection basket is located within the through-channel, intercepting debris in the water flow and storing it inside. To improve collection efficiency, a rotating brush is typically installed at the front of the robot. When encountering difficult-to-collect debris, the rotating brush primarily uses its rotation to pull the debris into the collection basket. The two end shafts of the brush pass through the robot body, leaving a gap between the brush and the body. Therefore, during rotation, it is easy for debris such as ropes, cloth, or branches to become entangled, leading to limited power or even jamming. Thus, an anti-entanglement brush mechanism needs to be designed. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an anti-tangling roller brush mechanism with a protective cover to prevent debris from getting tangled on the spindle and to prevent the roller brush from jamming.

[0004] The purpose of this utility model can be achieved through the following technical solution: An anti-tangling roller brush mechanism includes a frame, a roller brush, a spindle, and a protective cover. The roller brush includes a cylindrical body and paddles. The body has a central hole along its length. The spindle passes through the central hole and rotates synchronously with the body. The two ends of the spindle are rotatably connected to the two side walls of the frame. Several paddles are evenly distributed and fixed to the circumferential wall of the body. The inner side of the protective cover has a slot, and the end face of the paddle is inserted into the slot. The inner side of the frame has a circular groove, and the outer side of the protective cover is embedded in the circular groove.

[0005] Furthermore, the protective cover has a frustum portion and a cylindrical portion, with the slot located on the cylindrical portion.

[0006] Furthermore, the front end of the cylindrical portion has an inwardly bent flange. The flange increases the contact area between the slot and the paddle, enhancing the firmness of the connection between the roller brush and the protective cover.

[0007] Furthermore, the cross-section of the mandrel is a regular hexagon, and the central hole is a regular hexagonal hole.

[0008] Furthermore, three bodies are threaded through the spindle, each body having eight paddles.

[0009] The motor on the outside of the frame is connected to one end of the spindle. The motor drives the spindle to rotate, and as the roller brush rotates, it pushes surface debris into a collection basket inside the frame. A protective cover fills the gap between the roller brush and the frame. Because the protective cover is embedded in a circular groove in the frame, it provides all-around protection for the spindle, preventing it from coming into contact with debris. The roller brush rotates along with the protective cover, and since the cover does not directly contact the frame, it does not add extra strain to the motor.

[0010] Compared with existing technologies, this anti-tangling roller brush mechanism has the following advantages:

[0011] 1. Since one side of the protective cover is embedded in the circular groove of the frame and the other side is engaged with the paddle, it protects the spindle in all directions and can prevent the spindle from coming into contact with debris and affecting its normal rotation. Therefore, this roller brush mechanism can prevent the spindle from getting tangled in ropes, cloth or branches and leaves during rotation, which would cause the rotation to be obstructed or directly jammed.

[0012] 2. Due to the large outer diameter of the protective cover, it is not easy for debris to get tangled, reducing the failure rate of the roller brush jamming. Attached Figure Description

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1 , Figure 2 , Figure 3As shown, this anti-tangling roller brush mechanism includes a frame 1, a roller brush 2, a spindle 3, and a protective cover 4. The roller brush 2 includes a cylindrical body 21 and paddles 22. The body 21 has a central hole 23 along its length. The spindle 3 passes through the central hole 23 and rotates synchronously with the body 21. The two ends of the spindle 3 are rotatably connected to the two side walls of the frame 1. Several paddles 22 are evenly distributed and fixed to the circumferential wall of the body 21. The inner side of the protective cover 4 has a slot 43, and the end face of the paddle 22 is inserted into the slot 43. The inner side of the frame 1 has a circular groove, and the outer side of the protective cover 4 is embedded in the circular groove.

[0022] like Figure 5 As shown, the protective cover 4 has a frustum portion 41 and a cylindrical portion 42, with a slot 43 located on the cylindrical portion 42. The front end of the cylindrical portion 42 has an inwardly bent flange 44. The flange 44 increases the contact area between the slot 43 and the paddle 22, enhancing the firmness of the connection between the roller brush 2 and the protective cover 4.

[0023] like Figure 4 , Figure 6 As shown, the cross-section of the mandrel 3 is a regular hexagon, and the central hole 23 is a regular hexagonal hole. Three bodies 21 are threaded through the mandrel 3, and each body 21 has eight paddles 22.

[0024] A motor on the outside of the frame 1 is connected to one end of the spindle 3. The motor drives the spindle 3 to rotate, and the spindle 3 rotates synchronously with the roller brush 2. When the roller brush 2 rotates, it pushes the debris on the water surface into the collection basket inside the frame 1, thus achieving the function of collecting debris from the water surface. A gap is left between the roller brush 2 and the frame 1 to prevent the roller brush 2 from scraping the frame 1, but this can easily cause the spindle 3 to be exposed and entangled with debris such as ropes, cloth, or branches. Therefore, a protective cover 4 is installed between the frame 1 and the roller brush 2. The protective cover 4 fills the gap between the roller brush 2 and the frame 1. Since the protective cover 4 is embedded in the circular groove of the frame 1, it protects the spindle 3 from all directions and prevents the spindle 3 from contacting debris.
