New description: [New technical field] This creation is about a kind of fingerprint imaging nozzle can, especially the design of fingerprint imaging nozzle cans which uses latent acetate to reveal latent fingerprints. Soil [Previous technique], the pattern and the palm print are the texture of the skin of the human finger and the palm of the hand. When the finger and palm of the person touch the object, the fingerprint can usually be left on the item. Since each person's fingerprints and palm prints are different, each person's fingerprints are unique and unique. Therefore, these imprints left on the items are used as evidence in criminology and forensic science. However, the fingerprint printed on the item is not easy to be found. It is also called the latent fingerprint 〇_tfing coffee (4). It must be developed or made visible by special technical methods, so that the fingerprint can be found and collected by the forensic personnel. And compare. The imaging method of fingerprint collection in the well-known laboratory mainly includes cyano-secret (commonly known as three-second glue, instant glue or 5_) smoked display method, stone sulphuric acid method and section three-spot method (Ninghai Delin), for different Fingerprints on the surface of the material, each with the best way to visualize the fingerprints'. For example, the ninth ketone method is most suitable for use on porous materials: (paper, leather, wood, etc.), but not suitable for use on metal objects and smooth surfaces (such as glass). , car, gate, smooth surface, etc.; and the acrylonitrile __ law can be applied to metal objects and smooth surface is not suitable for use on porous articles. '亍 氰 cyanoacrylic acid g is a method commonly used in criminal identification towels. The principle is that the gas of nitrogen propylene acetate is reacted with the water in the fingerprint and the amine group U to further reveal the fingerprint. The conventional operation method is to design the isolation chamber in the M429936 laboratory, put the cyanopropylene acetate into the heating plate, and then use the heater to heat the cyanopropylene acetate to generate smoke, when the smoke and the fingerprint are in the fingerprint. The water reacts with the amino acid molecules to reveal an off-white fingerprint. However, suspicious items that leave latent fingerprints at the crime scene are not able to bring back the above-mentioned imaging methods in the experiment. Even if they can be brought back, the cost will be too high. Therefore, the current technology is expected to directly implement the cyanopropylene acetate smoking method at the crime scene, such as the portable on-site fingerprint display kit shown in China No. M344530. However, similar to the above-mentioned cyanopropylene acetate smoking method or its apparatus which can be directly implemented at the crime scene, it is still necessary to use a heater to heat the cyanopropylene acetate to generate smoke, and the smoke is not directional, so it is easy to go around. Contamination, sometimes it is necessary to implement appropriate protective measures, so there are still many inconveniences in the implementation. Thereafter, for example, the invention discloses that the anion-catalyzed polymerization smoker is not required to be externally heated, and the functional substance of a large amount of nucleophile is completely immersed in the liquid three-second gel to catalyze the three-second gel polymerization. The high-temperature smoking method, although it eliminates the problem of the heater, still requires the implementation of a complicated smoker, which cannot be implemented particularly easily and quickly, and is also expensive to manufacture. [New Content] The purpose of this creation is to provide a fingerprint imaging spray can to achieve direct fingerprint collection on the spot. The collection process is simple, convenient, fast, low cost, and avoids contamination of other items. In order to achieve the above object, the present invention provides a fingerprint imaging spray can, which preferably comprises: a spray can filled with a fingerprint imaging spray; the spray M429936 can comprises a container and a nozzle communicating with the container; The component of the fingerprint developing spray comprises 5 to 50 parts by weight of an ethyl cyanoacrylate (ECA) reactant, and 95 to 50 parts by weight of a dispersing agent; whereby the fingerprint can be sprayed using the spray can The agent is sprayed directly toward the surface of the article printed with the fingerprint. A fingerprint developing spray can according to the above preferred embodiment, wherein the spray can is a push spray can. According to the preferred embodiment of the present invention, the dispersing agent is a highly volatile solvent capable of dissolving or diluting ethyl cyanoacrylate, such as φ alcohols, ethers, acids, esters, ketones. , an aliphatic hydrocarbon or an aromatic carbon compound. According to the preferred embodiment of the present invention, the spray can is a pressure spray can, and the fingerprint development spray can be added with a weight of 05 to 50 in order to respond to the pressure spray can. A propellant comprising propylene butane liquefied gas, dioxane, chlorofluorocarbon gas, compressed air, carbon dioxide or nitrogen. In this way, the fingerprint imaging spray can of the present invention can provide the forensic personnel to carry the fingerprints to the crime scene, and as long as the sealed object faces the suspicious object after opening, the nozzle of the spray can is pressed at an optimal distance of 30 cm to make the inside of the container The ethyl cyanoacrylate (ECA) reactant is atomized through a nozzle and directionally dispersed onto the surface of the suspected object. When the spray reacts with the water in the fingerprint and the amino acid molecule, an off-white fingerprint is revealed. Therefore, this creation can achieve the direct collection of fingerprints on the spot, the collection process is simple and convenient, the cost is low, and the effects of avoiding other items are avoided.
