Six-use spray gun for dental department

Abstract

The invention relates to a six-use spray gun for dental department and belongs to the technical field of dental spray guns. The six-use spray gun includes a gun body portion and a water treatment portion. The gun body portion includes an outer sleeve tube. A gun head is arranged on one end of the outer sleeve tube and is provided with a spray rod. A gas heating assembly and a double-piston flow rate switch assembly are arranged inside the outer sleeve tube. The water treatment portion includes a water heater, a water switching valve body, and a pipeline. The pipeline includes a gas pipeline, a hot water pipeline and a cold water pipeline, wherein the gas pipeline is connected to the gun body portion; the hot water pipeline is successively connected to the water heater and the water switching valve body; and the cold water pipeline is connected to the water switching valve body which is then connected to the gun body portion. The gas heating assembly, the double-piston flow rate switch assembly, the water heater and the water switching valve body are connected to a controller. The spray gun can output hot air, hot water, hot fog, cold air, cold water and cold fog, wherein the temperature of the hot air, hot water and hot fog can be regulated properly through settings to reach clinically demanded temperature. In addition, water steam can be quickly heated and switched.

Description

technical field [0001] The invention relates to a dental six-purpose spray gun, which belongs 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 invention is: to provide ...
