Description
Technical field
This utility model relates to a kind of investigation dusting device, particularly a kind of investigation fingerprint displaying dusting device.
Background technology
In criminal investigation, sometimes need to extract the impression of the hand of scene of a crime, and traditional impression of the hand extracting method is to dip various powder by the hand-held hairbrush of investigative technique personnel to brush at the suspicion position, re-use and manifest impression of the hand after hairbrush brushes unnecessary powder, the brushing of adopting traditional mode to carry out powder exists efficient low, and powder consume is large and be difficult to the shortcoming such as recovery.
The utility model content
The technical problem that this utility model solves has provided a kind of investigation fingerprint displaying dusting device, this utility model main purpose is to solve the present investigative technique personnel problems such as to carry out the existing efficient of fingerprint displaying low, and the powder consume is large that adopt hairbrush to dip various powder.
For solving the problems of the technologies described above, this utility model investigation fingerprint displaying dusting device, comprise the pistol type plastics housing, air exhauster, storage powder box and transparent anti-leakage cover, described pistol type plastics housing is comprised of three parts, be respectively tubular body, housing middle part and handheld terminal, described air exhauster is arranged at the middle part of tubular body, the described air exhauster left and right sides is equipped with exhaust outlet, the left side exhaust outlet of described air exhauster is connected in transparent anti-leakage cover by flour extraction pipe, the right side exhaust outlet of described air exhauster is connected in the storage powder box that is arranged at the housing middle part by powder absorbing pipe, described housing middle part also is provided with control panel, one side of described handheld terminal is established control knob, accumulator is established in inside, and described control panel is connected in air exhauster by power line respectively, control knob and accumulator.
Described storage powder box is provided with powder and adds mouth, and the upper port that described powder adds mouth is provided with sealing-plug.
Charging socket is established in the bottom of described handheld terminal.
The beneficial effects of the utility model are: this utility model investigation fingerprint displaying dusting device, the investigation automatic powder spraying of fingerprint displaying and the automatic recovery of unnecessary powder have been realized, have simple to operate, easy to use, can greatly improve the efficient of scene of a crime impression of the hand extraction and the quality of fingerprint displaying.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is this utility model front view;
Among the figure: 1-pistol type plastics housing, 11-tubular body, 12-housing middle part, 13-handheld terminal, 131-charging socket, 2-air exhauster, 21-exhaust outlet, 3-storage powder box, 31-powder add mouth, 32-sealing-plug, the transparent anti-leakage cover of 4-, 5-flour extraction pipe, 6-powder absorbing pipe, 7-control panel, 8-control knob, 9-accumulator.
The specific embodiment
As shown in Figure 1, a kind of investigation of this utility model fingerprint displaying dusting device, comprise pistol type plastics housing 1, air exhauster 2, storage powder box 3 and transparent anti-leakage cover 4, described pistol type plastics housing 1 is comprised of three parts, be respectively tubular body 11, housing middle part 12 and handheld terminal 13, described air exhauster 2 is arranged at the middle part of tubular body 11, described air exhauster 2 left and right sides are equipped with exhaust outlet 21, the left side exhaust outlet of described air exhauster 2 is connected in transparent anti-leakage cover 4 by flour extraction pipe 5, the right side exhaust outlet of described air exhauster 2 is connected in the storage powder box 3 that is arranged at housing middle part 12 by powder absorbing pipe 6, described housing middle part 12 also is provided with control panel 7, one side of described handheld terminal 13 is established control knob 8, accumulator 9 is established in inside, and described control panel 7 is connected in air exhauster 2 by power line respectively, control knob 8 and accumulator 9.
During work, press control knob 8, thereby realize the control of 7 pairs of air exhauster 2 rotating speeds of control panel by regulating control knob 8, air exhauster 2 high speed rotating under the control of control knob 8, can form certain pressure differential this moment between air exhauster 2 and storage powder box 3, under the effect of air pressure, the powder in the storage powder box 3 enters air exhauster 2 through powder absorbing pipe 6, the powder that enters in the air exhauster 2 enters flour extraction pipe 5 under the wind-force effect of taking out extension set, finally by transparent anti-leakage cover 4 ejections.The unnecessary powder of ejection, by adjusting control knob 8, so that air exhauster 2 reverse rotations, the unnecessary powder of ejection this moment sucks air exhauster 2 through transparent anti-leakage cover 4, be blown into powder absorbing pipe 6 with the rotation wind-force of taking out extension set 4 and enter again at last the 3 interior storages of storage powder box, in order to reusing.
Described storage powder box 3 is provided with powder and adds mouth 31, and the upper port that described powder adds mouth 31 is provided with sealing-plug 32.Design is to storage powder box 3 interior additional interpolation powder for convenient like this.
Except the described technical characterictic of above-mentioned description, be the known technology of those skilled in the art.
