Multifunctional ultrasonic atomization fuming instrument for potential trace development

Abstract

The invention provides a multifunctional ultrasonic atomization fuming instrument for potential trace development, which comprises an ultrasonic atomization mechanism and a potential trace development box, the ultrasonic atomization mechanism is communicated with the potential trace development box, wherein, the ultrasonic atomization mechanism comprises a water medium container, water and an ultrasonic oscillation plate are arranged in the water medium container; a chemical reagent oscillation film container which is arranged on the water medium container; an oscillation film which is arranged between the water medium container and the chemical reagent oscillation film container; and an atomization air supply device which is connected with the chemical reagent oscillation film container. The instrument is a device which is based on the principle of ultrasonic atomization and can atomize ninhydrin, DFO and other chemical reagents to fine fog drips according to the technical requirements of potential traces; due to that the specific weight of the generated aerosol is greater than that of air, the aerosol can be rapidly settled and generate the combination chemical reaction with footprints and fingerprints on the surface of an object, thereby clearly developing the potential traces.

Description

technical field [0001] The invention relates to an atomization and fumigation display device, in particular to an ultrasonic atomization and fumigation display device, which is based on the principle of ultrasonic atomization, so that potential traces can be clearly displayed. Background technique [0002] The traditional chemical display of potential traces has many modes such as spraying, soaking, and wiping, but the above modes have many shortcomings, such as the diffusion of potential traces, contamination of inspection materials, uneven coating liquid, waste of liquid medicine, and complicated operation. The detailed characteristics of the traces of loss, most importantly, will cause irreversible damage to the physical evidence, making it lose the validity of the court complaint, thus limiting the scope of use of the chemical visualization method of potential traces. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a potential ...

Problems solved by technology

[0002] The traditional chemical display of latent traces has many modes such as spraying, soaking, and wiping, but the above-mentioned modes have many shortcomings, such as the diffusion of potential traces, contamination of test materials, uneven coating, waste of liquid medicine, cumbersome operation, etc. The detailed characteristics of the loss traces, the most important thing is that it will cause irreversible damage to the physical evidence, making it lose the effectiveness of court proceedings, thus limiting the scope of use of potential trace chemical visualization methods
