Micron-sized electrothermal iodine spray gun

Abstract

The invention provides a micron-sized electrothermal iodine spray gun which comprises a spray gun body; the spray gun body comprises a gun barrel and a gun handle; a heating pressure bin is arranged in the gun barrel; an electric heating plate with a certain thickness is arranged on the outer surface of the heating pressure bin; an inner wall back plate is arranged in the heating pressure bin and connected with a miniature air compressor through a pipe diameter internal pressure sealing connecting rod; a metal net is further arranged in the heating pressure bin and connected with a miniature rotating motor, so that the heating pressure bin is driven to rotate; one end of the heating pressure bin is connected with a variable nozzle; the variable nozzle is provided with a switch lock; the switch lock is connected with a trigger device; the trigger device is connected with a micro air compressor; a lithium battery and a miniature transformer are arranged in the gun handle; one end of the miniature transformer is electrically connected with the lithium battery; and the other end of the miniature transformer is electrically connected with the electric heating plate. According to the micron-sized electrothermal iodine spray gun, the effects of improving the fuming efficiency and saving energy are achieved by mainly utilizing an electric heating eddy current heating mode and a micron-sized spraying mode.

Description

technical field [0001] The invention relates to the technical field of spray guns, in particular to a micron-scale electrothermal iodine spray gun. Background technique [0002] The traditional methods of displaying sweat-submerged fingerprints on ordinary paper, wall fingerprints, and sweat-submerged fingerprints on thermal paper, such as (silver nitrate visualization method, ninhydrin solution method, DFO method, etc.), cannot effectively display the fingerprints on these objects. Sweat hidden fingerprints. When thermal paper encounters organic solvent, black pollution background will be produced on the film surface, which will affect the display of fingerprints, and even make the entire film surface black, resulting in the disappearance of fingerprints on it. The traditional method is helpless for the sweaty handprints on the wall. When the direct heating method is used to display latent fingerprints on thermal paper, the display temperature is difficult to control, and...

AI Technical Summary

Problems solved by technology

When the direct heating method is used to display latent fingerprints on thermal paper, the display temperature is difficult to control, and it is easy to contaminate the test material. Only the fingerprints on the surface of the thermal paper film can be displayed, and the fingerprints on the back cannot be resolved. have great limitations
