Description

Technical Field

[0001] The utility model relates to the technical field of dental medical devices, and particularly relates to a sand powder tank of a sand blasting dental scaler. Background Art

[0002] A sand blasting dental scaler uses compressed gas (usually air) to lift dental sand blasting powder (the main components are usually sodium bicarbonate, glycine, and erythritol) and spray it onto the tooth surface, where it converges with the liquid medium (usually water) sprayed out together to remove dental plaque, soft dirt, tobacco stains, tea stains, etc. on the tooth surface, achieving the purpose of cleaning teeth. When using a sand blasting dental scaler, a sand powder tank for accommodating sand powder needs to be equipped. Compressed gas is introduced into the sand powder tank to drive the sand powder to be transported to the sand blasting handle and then sprayed out from the nozzle. However, currently, the sand powder in the sand powder tank is prone to getting damp and caking, and the sand powder is likely to be blocked during the transportation process of the air outlet pipeline and the air-sand pipeline, affecting the use effect.
