Abstract

The invention discloses a sand dredging device which comprises a shell, a connector, a pressing head, a pressing spring and a dredging nozzle. The shell is provided with a first through hole and a conical hole. A connecting table of the connector is in thread connection with the shell. A connector body is connected with the connecting table. The connector body communicates with external high-pressure gas, and thus a high-pressure environment is provided in a first through hole. The pressing head is in sliding connection with the shell and is located in the first through hole. A conical head ofthe pressing head is pressed on the conical hole through the pressing spring. The dredging nozzle is fixedly connected with the conical head and is provided with a fourth through hole and a gas channel. A sand spraying head is placed on the dredging nozzle, the dredging nozzle is pressed, the conical head slides toward the side close to the connecting table, thus the gas channel communicates withthe conical hole, high-pressure gas enters the fourth through hole from the conical hole through the gas channel, and then enters the sand spraying head to blow out blocking sand powder and water crystalline solid out of the tail portion of a handle, the problem of sand blocking is solved effectively and rapidly, and the sand spraying and tooth cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the field of treatment and prevention of dental diseases, in particular to a sand blower. Background technique [0002] The sandblasting tooth cleaner is a kind of dental cleaning equipment. It uses a special sandblasting tooth powder (with sodium bicarbonate powder as the main component), and sprays it on the tooth surface through the sandblasting mobile phone head to remove dental plaque and pigment. This method is suitable for cleaning dental plaque and pigment spots in the interdental spaces that are difficult for ultrasonic scalers to reach, and the cleaning efficiency for tooth surface pigments is much higher than that of ultrasonic scalers. But sandblasting dentifrice mixed with water at the sandblasting handle will form solid crystals and block the handle, causing the sandblasting handle to be unable to be used for normal sandblasting and tooth cleaning. [0003] There are currently two solutions to this problem: In th...
