Dental Spray Gun with Hydro-Air Heating

Abstract

The invention relates to a dental spray gun having a steam heating function, and belongs to the technical field of dental spray guns. The spray gun comprises a gun body part and a water treatment part. The gun body part comprises an outer sleeve tube. One end of the outer sleeve tube is provided with a gun head. The gun head is provided with a spraying bar. The inside of the outer sleeve tube is provided with a steam heating assembly and a pneumatic-controlled electric switch assembly. The water treatment part comprises a water heater, a water switching valve body and pipelines. The pipelines comprise a gas pipeline, a hot-water pipeline and a cold-water pipeline. The gas pipeline is connected to the gun body part. The hot-water pipeline is connected to the water heater and the water switching valve body in order. The cold-water pipeline is connected to the water switching valve body. The water switching valve body is connected to the gun body part. The steam heating assembly, the pneumatic-controlled electric switch assembly, the water heater and the water switching valve body are connected to a controller. The spray gun can achieve output of hot wind, hot water, hot mist, cold wind, cold water and cold mist, wherein temperatures of the hot wind, the hot water and the hot mist can be adjusted properly through setting to reach a clinical required temperature and the steam can be rapidly heated and switched.

Description

technical field [0001] The invention relates to a dental spray gun with water vapor heating function, belonging to the technical field of dental spray guns. Background technique [0002] In winter, doctors will reduce or not use three-purpose spray guns in dental treatment, and instead interrupt treatment. When patients stand up and rinse their mouths, when the existing three-purpose spray guns work in a low-temperature treatment environment, cold wind, cold water, and cold mist will cause irritation to the wound surface of patients. The patient is uncomfortable, and there is an urgent clinical need to design a six-purpose spray gun with hot air, hot water and hot mist functions, and it is required that the water vapor can be quickly heated and switched between cold and hot. There is currently no suitable solution on the market. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present inventi...
