Abstract

The invention discloses a spray gun device and belongs to the technical field of spraying tools. The spray gun device comprises a gun body, wherein a spray nozzle is formed in the gun body; a siphon channel which vertically extends is formed in a spray head; the spray head is in threaded connection with a tank body; a material suction pipe is arranged on the spray head; a trigger is hinged to the gun body; a pressure adjusting valve is arranged at the air inlet end of an air inlet channel; a transverse needle plug is glidingly mounted on the gun body, penetrates through the trigger and is controlled by the trigger; a siphon gap is formed between the spray nozzle and the needle plug and is communicated with the siphon channel; a spray-blow channel communicated with an airflow channel is transversely formed in the gun body; a spray-blow gap communicated with the spray-blow channel is formed between the spray nozzle and an airflow cap and faces the discharging hole of the spray nozzle; an air exchange channel communicated with the spray-blow channel and the tank body is formed in the spray head; an air inlet slide valve is arranged on the air exchange channel. According to the spray gun device, the technical problem that the spraying effect is influenced by negative pressure in the tank body is solved; the spray gun device can be widely applied to spraying of oil paint and coatings.

Description

technical field [0001] The invention relates to a spray tool, more specifically to a spray gun, and belongs to the technical field of spray tools. Background technique [0002] Spray gun is a relatively common spraying tool in daily life. It has a wide range of applications. For example, a spray gun can be used as a tool for spraying paint or coatings, which is convenient and labor-saving. There are many types of spray guns on the market. According to the feeding method, It can be roughly divided into three types: siphon type, gravity type and pressure type. Among them, the siphon air spray gun is the most common and widely used. Its principle is that there is a material tank at the lower end of the spray gun, and the compressed air flows through the nozzle of the spray gun at high speed, creating a partial vacuum around it, sucking the paint in the material tank into the nozzle and atomizing it into The paint mist is evenly sprayed on the surface of the object. [0003] I...
