[0002] The dental three-in-one gun is a common device on the dental comprehensive treatment table. The dental clinic is a medium-risk area, and the cleaning and hygiene management level should reach the sanitary level. According to the regulations, once the environmental surface of various risk areas is contaminated by patient body fluids, blood, etc., the contaminated area should be cleaned and disinfected immediately. Therefore, for the dental three-in-one gun that is contaminated during treatment, it should be "cleaned and disinfected once used" and follow the principle of cleaning first and then disinfecting.

[0003] The dental three-in-one gun is generally equipped with a pipe for spraying water and air and two buttons. One is a water spray button, which is used to control the pipe to spray water; the other is an air spray button, which is used to control the pipe to spray air. Pressing both buttons at the same time can spray water mist. Disinfection of the dental treatment table waterway includes disinfection and flushing of the dental three-in-one gun waterway. In order to ensure that the disinfectant and distilled water for flushing flow out smoothly, the operator needs to press the water spray button of the dental three-in-one gun for a long time, which can easily cause finger fatigue of the operator.
