Orthodontics mainly studies the etiology, diagnosis and analysis of malocclusion, as well as its prevention and treatment. Orthodontics can achieve the effect of beautifying teeth. During the orthodontic process, the teeth are usually cleaned. The staff usually passes water into the control handle, and the water can be sprayed out from the nozzle on the control handle. The staff usually holds the control handle and uses the nozzle on the control handle to clean the teeth. However, the nozzle is not convenient to adjust the angle when the staff holds the control handle, and it is not convenient to operate when cleaning various parts of the teeth. At the same time, the control handle is not easy to store.

DETAILED DESCRIPTION

[0018] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] Example

[0020] See also Figures 1-4The present invention is an oral cleaning device, comprising a handle 1, wherein the top of the handle 1 is rotatably mounted with a nozzle 2, a support 4 is fixedly provided on the upper side of the outer wall of the handle 1, a rotating shaft 3 is rotatably mounted on the support 4, a leather cover 5 is fixedly provided on the outer wall of the bottom of the rotating shaft 3, a connecting plate 6 is rotatably connected to the top of the rotating shaft 3, the nozzle 2 is rotatably mounted on the connecting plate 6, a driving gear 7 is fixedly provided on the rotating shaft 3, a driven gear 8 is fixedly provided on the nozzle 2, the driving gear 7 and the driven gear 8 are meshed with each other, two sets of support plates 10 are symmetrically fixedly connected on the outer wall of the handle 1, and the two sets of support plates 10 are rotatably mounted There is a support rod 11, a limit groove is provided on the rocker 9, and the rocker 9 is installed on the support rod 11 through the cooperation of the limit groove and the support rod 11. The front and rear ends of the rocker 9 are respectively in contact with the inner sides of the two groups of support plates 10. A dynamic pressure block 12 is fixed on the inner side of the top of the rocker 9, and a fixed pressure block 13 is fixed on the outer wall of the handle 1 to match the dynamic pressure block 12. The leather case 5 is clamped on the dynamic pressure block 12 and the fixed pressure block 13. A tightening spring 14 is fixedly connected between the inner bottom end of the rocker 9 and the outer wall of the handle 1. When in use, the tightening spring 14 is initially in a compressed state, and the compression of the tightening spring 14 applies a rightward force to the bottom of the rocker 9. The thrust of the support rod 11 is against the lower end of the limit slot. Under the principle of lever, the rocker 9 applies a left thrust to the leather case 5 through the dynamic pressure block 12, thereby pressing the dynamic pressure block 12 on the leather case 5. The leather case 5 is clamped by the dynamic pressure block 12 and the fixed pressure block 13, so that the rotating shaft 3 will not rotate. The handle 1 can be held by hand to clean the corresponding position of the teeth through the nozzle 2, which also prevents the nozzle 2 from rotating. When the angle of the nozzle 2 needs to be adjusted to adjust different positions of the teeth, the handle 1 can be held, the palm of the hand can be pressed under the rocker 9, and then the rocker 9 can be pressed to the left, and the tightening spring 14 is further tightened. After the tooth is flushed, the pressure on the rocker plate 9 is released, and the dynamic pressure block 12 is lifted, and the grip on the leather case 5 is released. Then, the thumb is placed on the leather case 5 and gently rotated to make the rotating shaft 3 drive the driving gear 7 to rotate. The driving gear 7 drives the nozzle 2 to rotate through the driven gear 8, thereby realizing the angle adjustment of the nozzle 2. After the adjustment, the pressure on the rocker plate 9 can be released, so that the dynamic pressure block 12 can re-clamp the leather case 5 to ensure that the angle of the nozzle 2 is fixed during flushing and avoid rotation. This can effectively fix the nozzle and prevent the nozzle from rotating when cleaning the corresponding position of the teeth, thereby improving practicality.

[0021] An anti-slip cover 15 is fixed on the outer wall of the bottom of the seesaw 9 . The anti-slip cover 15 can prevent the seesaw 9 from slipping when the palm presses the seesaw 9 .

[0022] Anti-skid pads 16 are fixedly provided on the inner walls of the curved surfaces of the dynamic pressure block 12 and the fixed pressure block 13. By providing the anti-skid pads 16, the dynamic pressure block 12 and the fixed pressure block 13 can clamp the leather case 5 more tightly and firmly to avoid slipping.

[0023] A reinforcing plate 17 is fixedly connected between the outer sides of the two groups of support plates 10 and the outer wall of the handle 1; by providing the reinforcing plate 17, the connection between the support plate 10 and the handle 1 can be made more firm and stable.

[0024] The outer wall of the leather case 5 is provided with anti-skid patterns 18 ; by providing the anti-skid patterns 18 , the surface friction of the leather case 5 can be increased, so that the leather case 5 is not prone to slipping when the thumb rotates it.

[0025] The present invention is an oral cleaning device, and its working principle is that when in use, the tensioning spring 14 is initially in a compressed state, and the compression of the tensioning spring 14 applies a rightward thrust to the bottom of the rocker 9, and the support rod 11 is against the lower end of the limit groove. Under the principle of leverage, the rocker 9 applies a leftward thrust to the leather case 5 through the dynamic pressure block 12, thereby pressing the dynamic pressure block 12 on the leather case 5, and clamping the leather case 5 through the dynamic pressure block 12 and the fixed pressure block 13, so that the rotating shaft 3 will not rotate, and the handle 1 can be held by hand to clean the corresponding position of the teeth through the nozzle 2, which also prevents the nozzle 2 from rotating. When the angle of the nozzle 2 needs to be adjusted , to adjust different positions of the teeth, you can hold the handle 1, press the palm under the rocker 9, and then press the rocker 9 to the left. The tightening spring 14 is further compressed, and the rocker 9 flips outward to lift the dynamic pressure block 12, loosening the clamping of the leather case 5. Then, use your thumb to press on the leather case 5 and gently turn it to make the rotating shaft 3 drive the driving gear 7 to rotate, and the driving gear 7 drives the nozzle 2 to rotate through the driven gear 8, thereby realizing the angle adjustment of the nozzle 2. After the adjustment, you can release the pressure on the rocker 9, so that the dynamic pressure block 12 clamps the leather case 5 again, ensuring that the angle of the nozzle 2 is fixed during flushing to avoid rotation.
