[0002] The dental air-water gun is a commonly used medical device in dental treatment. It is mainly composed of a gun body, a nozzle, a control switch, and some parts of the pipes connecting the air and water circuits. It produces different spray modes by precisely controlling the compressed air and water flow. It plays a variety of roles in the oral diagnosis and treatment process. On the one hand, it can use high-pressure water mist to rinse the tooth surface, effectively remove soft plaque, food residues on the tooth surface, and debris in the pits and fissures, creating conditions for doctors to clearly observe the oral condition; on the other hand, after tooth preparation and cavity preparation operations, it can quickly clean up debris and powder, keep the surgical area clean, and reduce the risk of infection. It can also cool high-speed turbine mobile phones and other instruments during operation to avoid damage to the pulp tissue due to excessive heat generation. It is a key tool to ensure the smooth progress of dental treatment and improve the treatment effect.

A plurality of movable mechanisms 2 are arranged equidistantly around the periphery, and the movable mechanism 2 includes a knob 201, and the knob 201 is arranged on the outside of the tank body 1, and the bottom of the knob 201 is fixedly connected with a threaded rod 202, and the top of the threaded rod 202 is rotatably connected with a fixed block 203, and the outer side of the fixed block 203 is threadedly connected with a threaded block 204, and the outer side of the threaded block 204 is fixedly connected with a roller 205, and the left side of the threaded block 204 is fixedly connected with a limiting block 206, and the bottom of the threaded rod 202 is rotatably connected with a connecting block 207, and the front side of the outer wall of the tank body 1 is fixedly connected with a placement block 16, and the outer side of the placement block 16 is fixedly connected with a hook 17, and a warning sign 18 is arranged on the right side of the outer wall of the tank body 1, and the outer side of the warning sign 18 is threadedly connected with a screw 19, and the air pump 9 is an electric air pump.

[0018] Working principle: first add an appropriate amount of flushing liquid into the tank body 1, and then inflate and pressurize the tank body through the air pump 9 until the required pressure is reached. The water outlet pipe 21 and the air outlet pipe 22 in the tank body 1 are connected to the spray gun 3 through the air storage tank 12. When the spray gun 3 needs to emit air, the air outlet button of the spray gun 3 is controlled. When the spray gun 3 needs to emit water, the water outlet button of the spray gun 3 is controlled. Water is emitted because the pressure inside the tank body 1 is greater than that outside the tank body, because the water outlet pipe 21 is arranged at the bottom of the tank body 1 and is flooded by the flushing liquid, and the air outlet pipe 22 is arranged in the middle and upper part of the tank body 1. Therefore, the air pressure in the tank body 1 can press the water in the tank body 1 through the water outlet pipe 21 out of the tank body 1 and into the spray gun 3.
