Description

Technical Field

[0001] The invention relates to the field of dental disease treatment and prevention, in particular to a sand clearer. Background Art

[0002] Sandblasting tooth cleaning machine is a dental tooth cleaning device that uses a special sandblasting tooth powder (with sodium bicarbonate powder as the main ingredient) to spray the sandblasting handpiece onto the tooth surface to remove dental plaque and pigment. This method is particularly suitable for cleaning dental plaque and pigment stains in the interdental spaces that are difficult to reach with ultrasonic tooth cleaning machines, and its cleaning efficiency for tooth surface pigments is much higher than that of ultrasonic tooth cleaning machines. However, when sandblasting tooth powder is mixed with water at the sandblasting handle, it will form solid crystals and block the handle, causing the sandblasting handle to be unable to be used for normal sandblasting tooth cleaning.

[0003] There are currently two solutions to this problem: a sand-clearing needle is configured in the instrument accessories, and the sand-clearing needle is used to pass through the sandblasting pipeline inside the sandblasting handle. The sand-clearing needle breaks the crystalline solids of sand powder and water to solve the problem of blockage of the sandblasting handle. However, the sand-clearing needle is a small metal needle. Passing through a longer internal pipeline of the handle, the sand-clearing needle cannot retain high strength and is easy to bend; when the crystalline solids of sand powder and water are harder, the sand-clearing needle cannot easily break them, and the operation requires a long time; when the crystalline solids of sand powder and water are large, the sand-clearing needle cannot easily break them; the second is to make the handle detachable, and after being blocked, it is immersed in hot water at a higher temperature to dissolve the crystalline solids of sand powder and water, but the efficiency is low and the operation is time-consuming.

[0039] Working principle and use process of the present invention: please refer to Figure 1 , Figure 2 and Figure 3 After the present invention is installed, the connector body 21 is connected to the external high-pressure air pipe, so that the high-pressure gas enters the third through hole 24 and the first through hole 11 through the second through hole 23 and maintains a high-pressure state. When the sandblasting handle 7 is blocked, the sandblasting head 6 on the sandblasting handle 7 is aligned with the nozzle 5 and inserted into the nozzle 5 for pressing. The nozzle 5 pushes the conical head 31 to move to the side close to the connecting platform 22, so that the airway 52 on the nozzle 5 is connected with the conical hole 12, and the second sealing ring 15 loses its sealing effect, so that the high-pressure gas enters the fourth through hole 51 through the airway 52, and then enters the sandblasting handle 7 through the sandblasting head 6, and finally blows out the blocked sand powder and water crystals from the handle tail 8, which can effectively and quickly solve the sand blockage problem and improve the efficiency of sandblasting and tooth cleaning. After cleaning, the sandblasting head 6 and the through nozzle 5 are separated, and the pressing head 3 will return to its original state under the action of the pressing spring 4 so as to facilitate the next use, thereby being able to be continuously recycled.
