Description
Technical Field
The utility model belongs to criminal technical field investigation equipment field, specific theory relates to a portable trace material evidence draws appearance.
Background
At present, public security personnel need to take the filter cotton and change after pulling out the suction nozzle when using the extraction appearance to extract the trace material evidence at the criminal crime scene, when extracting the material evidence, and the procedure is too loaded down with trivial details. Therefore, it is necessary to design a portable micro physical evidence extractor which can conveniently replace the filter cotton and collect physical evidence.
Disclosure of Invention
In order to overcome the problem that exists among the background art, the utility model provides a portable trace material evidence draws appearance, can be convenient take and change filter pulp, collect the material evidence fast.
In order to achieve the above purpose, the utility model is realized by the following technical scheme:
the portable trace material evidence extraction instrument comprises a suction head 1, a shell 2, a filter cotton fixing frame 3, filter cotton 4, a collection box 5, an exhaust fan 6, a handle 7 and a power switch 8; 2 front ends of casing install suction head 1, install on the fixed frame of filter pulp 3 and filter pulp 4, filter the fixed frame of filter pulp 3 and insert and establish in casing 2, the below opening part of casing 2 is installed and is collected box 5, 2 terminal and the 6 fixed connection of air exhauster of casing, be equipped with handle 7 on the air exhauster 6, be equipped with switch 8 on the handle 7, switch 8 and 6 electric connection of air exhauster.
Preferably, the handle 7 is further provided with a wind speed control switch 9, and the wind speed control switch 9 is electrically connected with the exhaust fan 6.
The utility model has the advantages that:
the utility model discloses a fixed frame of filter pulp of plug-in can change the filter pulp fast to can take out the material evidence of collecting after extracting. The collection box can collect slightly big material evidence that should not adsorb on the filter pulp, ensures that the material evidence of inhaling and getting can both be collected, can also adjust the size of suction according to the difference of gathering the position through wind speed control switch.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.
As shown in fig. 1-3, the portable micro physical evidence extraction instrument comprises a suction head 1, a shell 2, a filter cotton fixing frame 3, filter cotton 4, a collection box 5, an exhaust fan 6, a handle 7 and a power switch 8. The front end of the shell 2 is provided with a suction head 1, and the suction head 1 is provided with a flat opening and a round opening, so that the device can adapt to different places for sucking material evidence. The filter cotton 4 is installed on the filter cotton fixing frame 3, and the filter cotton 4 collects the sucked material evidence. The filter cotton fixing frame 3 is inserted in the shell 2, so that the filter cotton 4 is convenient to mount and take. The lower opening of the shell 2 is provided with a collecting box 5 for collecting slightly larger material evidence which is not suitable to be adsorbed on the filter cotton 4. The tail end of the shell 2 is fixedly connected with an exhaust fan 6, a handle 7 is arranged on the exhaust fan 6, a power switch 8 is arranged on the handle 7, the power switch 8 is electrically connected with the exhaust fan 6, and the power switch 8 controls the exhaust fan 6 to be connected or disconnected to work or stop.
Preferably, the handle 7 is further provided with a wind speed control switch 9, and the wind speed control switch 9 is electrically connected with the exhaust fan 6 and used for adjusting the wind power.
The utility model discloses a working process:
the required suction head 1 is inserted into one end of the shell 2, the filter cotton 4 is installed on the filter cotton fixing frame 3, and the filter cotton fixing frame 3 is inserted into the shell 2. The exhaust fan 6 is started to work by pressing the power switch 8, and the wind power can be adjusted by the wind speed control switch 9. After the collection is completed, the power switch 5 is pressed to stop working. The fixed filter cotton frame 3 is taken out, the filter cotton 4 is taken out for evidence obtaining, the collecting box 5 is taken out, material evidence in the collecting box 5 is collected, and the fixed filter cotton frame 3 and the collecting box 5 are inserted back to the original position after the collection is completed.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
