Non-destructive instantaneous display device for anti-generation

Abstract

The invention provides a non-destructive instantaneous display device for anti-generation. The instantaneous display device comprises the following parts: a water storage air intake assembly, an atomization assembly, an exhaust assembly, a heater and a controller; the water storage air intake assembly includes a fixed carrier, a water storage bottle installed on the fixed carrier and a fan arranged in an air cavity, and the fixed carrier is provided with an air cavity whose air inlet is in communication with the outside world; the atomization assembly comprises an ultrasonic atomizer which isin communication with the bottle inlet of the water storage bottle for atomizing water ultrasonic into nano-sized small water drops; the exhaust assembly comprises a porous exhaust funnel, one end ofthe porous exhaust funnel communicates with the air cavity and the ultrasonic atomizer, and the other end of the porous exhaust funnel communicates with the outside world; the porous exhaust funnel sleeves a heater to heat the small water drops to the preset temperature, the small water drops are mixed with gas blown out of the air cavity, and then blown out by the exhaust assembly; and the controller is electrically connected with the fan to control the blowing wind force of the fan, and electrically connected with the ultrasonic atomizer to control opening and closing of the ultrasonic atomizer, and is electrically connected with the heater to control and adjust the heating temperature of the heater. According to the technical scheme of the non-destructive instantaneous display device, the bionic breathing process can be achieved, and the extraction rate of on-site physical evidence is advantageously increased.

Description

technical field [0001] The invention belongs to the technical field of auxiliary devices for criminal investigation and evidence collection, and in particular relates to an anti-life and non-destructive transient display device. Background technique [0002] In the field of criminal investigation, for crime scene investigation, for example, for the display of physical evidence (fingerprint physical evidence), the traditional methods include powder painting, fumigation, chemical reagent treatment, and the use of natural breath of the human body to display. However, because the human body's breath may contain human body's spittle and contaminate evidence, the Ministry of Public Security has banned the use of human body's breath to show physical evidence in the last ten years. [0003] However, the breathing method has a unique effect on the display of physical evidence such as fingerprints, so it is an urgent problem to develop a device that can truly simulate the bionic human...
