After the equipment is used, the working cover 31 can be directly contracted and folded on the handle 3 like an umbrella, so that the equipment is convenient to carry.
According to the invention, after the working cover is assembled (such as 502 umbrella type fumigating and developing cover body, patent number 201520509679.7) is assembled, the region where the fingerprint is located is covered, and the 502 glue in the heater and the water and the dyeing reagent in the humidifier are respectively and automatically heated and humidified, so that the temperature and the humidity in the working cover are controlled, and the fingerprints attached to the plane and the non-plane in the case site are uniformly fumigated and developed or dyed, so that the complete extraction of the fingerprint characteristics is realized. The heater adopts the structural design that can decompose, both is convenient for wash, also is convenient for change to the washing inconvenience that the adhesion that has avoided 502 caused makes the fumigation display device can more convenient use. Meanwhile, the portable electric power generation device is simple in structure, convenient to operate, easy to carry and high in practicability.
Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the invention, and that, although the invention has been described in detail by means of 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.
