A siphon energy-saving hair gun

Abstract

The invention relates to a siphonic energy-saving blowing gun which comprises a handle, a wrench and a spray nozzle, wherein the upper end of the wrench is connected with the upper end of the handle, and rotates around the upper end of the handle, the spray nozzle is connected with the upper end of the handle on one side where the wrench is position, an air inlet joint is arranged at one end of the spray nozzle, an air outlet pipe is arranged at the other end of the spray nozzle, the internal diameter of the air inlet joint is smaller than that of the air outlet pipe, one end of the air inlet joint is communicated with the air outlet pipe through a central hole, transverse through holes are symmetrically formed in the center positions of the two sides of one side wall of the air outlet pipe, elliptical inclined holes are formed in the positions of the transverse through holes, the transverse through holes are formed in the centers of the elliptical inclined holes, the inclined angle between the long axis of each elliptical inclined hole and the central axis of the air outlet pipe is 15 degrees, and the bottoms of the elliptical inclined holes are communicated with the transverse through holes through inclined planes. The siphonic energy-saving blowing gun has a simple structure, pressurizes the compressed air by the siphon principle, is remarkable in effect, and is low in production cost.

Description

technical field [0001] The invention relates to the field of blow guns, in particular to a siphon energy-saving blow gun. Background technique [0002] Blowing guns are also called cleaning air guns, flow-increasing air guns, purge guns, air-saving blowing guns, etc. Blowing guns are widely used in the field of enterprise automation production. Installation of products, maintenance of mechanical equipment, cooling of products, relocation of products, drying and cleaning of products. [0003] The original blow guns generally use high-pressure gas to blow air directly through the outlet pipe, and there is no effective airflow lifting structure. Now there are some hair guns on the market that use the siphon principle. There are many siphon ports on the side wall of the air outlet pipe. Generally, there are two siphon ports. Using the siphon principle, the pressure of the blown gas is many times higher than the original high-pressure gas. The use effect is good, but this struc...

Problems solved by technology

Now there are some hair guns on the market that use the siphon principle. There are many siphon ports on the side wall of the air outlet pipe. Generally, there are two siphon ports. Using the siphon principle, the pressure of the blown gas is many times higher than the original high-pressure gas. The use effect is good, but this structure will make a lot of noise when it is used, and the structure is complicated, the processing is inconvenient, and the production cost is high
