[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides a car surface cleaning device for painting, including an elliptical frame 1. A sliding block 3 is slidably disposed in the inner cavity of the elliptical frame 1. An elastic mechanism is provided on one side of the sliding block 3, and a connecting block 7 is fixedly connected to the other side of the sliding block 3. One end of the connecting block 7 extends through the outside of one side of the elliptical frame 1, and a limiting piece 8 is fixedly connected to the end of the connecting block 7 outside the elliptical frame 1. A circular opening is formed on the outer surface of the sliding block 3, and a water source connecting pipe 4 is fixedly inserted into the top of the circular opening. A rotating shaft 20 is rotatably inserted into the bottom of the circular opening through a bearing. A small motor 5 is fixedly connected to the top of the sliding block 3, and the output of the small motor 5 is... Another rotating shaft 20 is fixedly connected to the output shaft, and gears 9 are fixedly sleeved on the outer surfaces of both rotating shafts 20. The two gears 9 mesh with each other, and the bottom end of the rotating shaft 20 on one side of the water source connecting pipe 4 is connected to a connecting cover 10. The top of the inner cavity of the connecting cover 10 has two grooves. A positioning pin 22 is fixedly inserted into the inside of one groove, and a bidirectional threaded rod 21 is rotatably connected to the inside of the other groove. A sliding groove 16 is slidably provided at both ends of the two grooves, and one end of each sliding groove 16 is threadedly sleeved on both ends of the bidirectional threaded rod 21. One end of the bidirectional threaded rod 21 passes through the outside of the connecting cover 10, and the bidirectional thread... A knob 19 is fixedly connected to one end of the rod 21 outside the connecting cover 10. The other ends of the two slide grooves 16 are slidably inserted into the two ends of the positioning post 22, and each of the two slide grooves 16 has an insert block 23 fixedly connected to an adjacent side. An insert block 18 is slidably inserted between the two insert blocks 23, and a fixing block 17 is fixedly connected to the bottom of the insert block 18. A cleaning sponge 11 is fixedly connected to the bottom of the fixing block 17. A handle 6 is fixedly connected to the top of the elliptical frame 1. When the elliptical frame 1 is in use, it is connected to a high-pressure water pump through a water source connection pipe 4 to deliver cleaning fluid and water. At the same time, the small motor 5 is turned on, and the two gears 9 mesh. When the connecting cover 10 is closed, it causes the cleaning sponge 11 to rotate, allowing the cleaning sponge 11 to receive cleaning fluid and water. The rotation is then used to clean the car surface. If the car roof is too wide to reach, the limiting piece 8 can be pushed, and the connecting block 7 can be used to move the sliding block 3. At this time, the cleaning sponge 11 will slide to the other side of the elliptical frame 1, thereby extending the area that the cleaning sponge 11 can clean. After cleaning, the connecting block 7 can be released, and the sliding block 3 can be returned to its original position through the elastic mechanism. This avoids the problem of limited cleaning area when the cleaning sponge 11 is cleaning the car surface.

[0021] To facilitate the sliding stability of the sliding block 3 inside the elliptical frame 1, grooves 16 are provided on both sides of the inner cavity of the elliptical frame 1, and sliding blocks 15 are fixed to both ends of the sliding block 3. The two sliding blocks 15 are respectively slidably disposed inside the two grooves 16, and the two sides of the sliding block 3 are respectively in contact with the two sides of the inner cavity of the elliptical frame 1.

[0022] It should be noted that the elastic mechanism includes a connecting cylinder 2, which is fixed to one side of the inner cavity of the elliptical frame 1. A spring 12 is fixed to one side of the inner cavity of the connecting cylinder 2, and a connecting piece 13 is fixed to one end of the spring 12. The connecting piece 13 is slidably disposed inside the connecting cylinder 2, and a pin 14 is fixed to one side of the connecting piece 13. One end of the pin 14 is fixed to the side of the sliding block 3 away from the connecting block 7. When the connecting block 7 is pushed, the pin 14 drives the connecting piece 13 to push the spring 12 to deform and generate elasticity inside the connecting cylinder 2, so that the elasticity of the spring 12 can be used to return the sliding block 3 to its original position.

[0023] Furthermore, in order to facilitate the water source connection pipe 4 to deliver water to the bottom rotating shaft 20 and deliver the water to the cleaning sponge 11, the bottom end of the rotating shaft 20 on one side of the water source connection pipe 4 is connected to the top of the inner cavity of the connecting cover 10, and the bottom end of the rotating shaft 20 is flush with the top of the inner cavity of the connecting cover 10.

[0024] Furthermore, to facilitate the replacement of the entire cleaning sponge 11, the plug block 18 has plug holes on both sides, and the two plug blocks 23 are slidably inserted into the two plug holes respectively, and the size of the two plug blocks 23 matches the size of the two plug holes.

[0025] To facilitate the cleaning of the sponge 11 and the receiving of water, the fixing block 17 is rotatably connected to the bottom of the connecting cover 10, and the top of the fixing block 17 fits against the bottom of the connecting cover 10, and the size of the fixing block 17 matches the size of the bottom of the connecting cover 10.
