Description

Technical Field

[0001] The invention belongs to the technical field of identification equipment, and belongs to a fingerprint visualization device for criminal technical trace identification, and specifically relates to a clippable and detachable portable fumigation display device for fingerprint visualization technology in handprint science. Background Art

[0002] In fingerprint visualization in trace identification, 502 fumigation is the most commonly used and important visualization method on smooth, non-permeable objects. Since the ethyl cyanoacrylate in 502 glue can rapidly undergo anionic polymerization and solidify under the catalysis of trace moisture and weak base, the ethyl cyanoacrylate in 502 can polymerize under the catalysis of moisture and certain organic substances in the fingerprint residue, thereby revealing white fingerprint lines. The 502 fumigation cabinet invented based on this principle has been used by domestic and foreign police agencies and judicial identification departments to extract fingerprint evidence and solve countless cases. It is still one of the most practical main equipment today.

[0003] However, the existing 502 fumigation cabinets are large in size and their prices range from tens of thousands to hundreds of thousands. The 502 fumigation cabinets are mainly divided into vertical fumigation cabinets, desktop fumigation cabinets, composite multi-chamber fumigation cabinets, 360° all-round fumigation cabinets, etc. The main part of the 502 fumigation cabinet is usually placed in the laboratory, which will take up a certain amount of space. However, it cannot be used for many trace-bearing objects (such as human bodies) that cannot be moved to the laboratory during on-site investigations. Therefore, there are certain usage limitations in the usage scenarios due to the inconvenience of carrying.

[0004] The portable 502 fumigation equipment currently available on the market is mainly hooded fumigation guns and unhooded fumigation guns, with prices ranging from several hundred yuan to several thousand yuan. The working principle of this fumigation gun is that the fumigation gun sprays flames under the action of the methane gas tank to heat and vaporize the 502 glue on the asbestos in the bullet, and the bullet will spray 502 glue gas for fumigation. Although this fumigation gun is portable, its disadvantages are also obvious. It needs to be held by a special person, and it is easy to miss the inspection if there is no fingerprint in a short time. There is no operating data of temperature, humidity, and heating time, and it is impossible to record the change process. The methane and asbestos may produce pollutants that affect the display results. In addition, flammable and explosive items are not allowed to be carried on airplanes and trains, and transportation is inconvenient. The hood is only suitable for horizontal planes, and the hood is harmful to the human body and the environment. Consumables are difficult to buy, and a designated special asbestos bullet must be used. 502 fumigation equipment is an essential laboratory equipment required by the criminal technology science trace identification profession, and its usage rate is extremely high. In actual on-site investigations or scientific research experiments, the environment and objects are complex and diverse, and manpower and cost are both problems. Data recording and accuracy are also an indispensable part. A fast, effective, unified and standardized instrument is needed to solve the above pain points. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a portable fumigation display device that can be clipped and detached, which can be used without the need for a dedicated person to hold it, and the heating temperature, humidity, and time changes are visible and controllable, the use site is flexible, the application objects are wide, it is small and portable, 502 glue and water can be added at any time, it is ready to use and disposable, and it is convenient to transport. After the fumigation is completed, the cover can be directly peeled off and discarded to prevent the diffusion of 502 glue gas and reduce pollution to people and the environment. It is safe and hygienic, and can be widely used in on-site investigation, inspection and identification, scientific research and other related aspects, reducing manpower and economic burdens, improving work efficiency, and the data is accurate and reliable, providing a strong guarantee for investigation and solving cases or scientific research.

A storage groove is opened on the surface of the smoke display instrument body. When the U-shaped hook is flipped toward the smoke display instrument body, the U-shaped hook is partially stored in the storage groove.

[0012] Furthermore, the cover body is made of HDPE film, and both ends of the HDPE film are provided with connectors. One end of the HDPE film is arranged on the edge of the open end of the fumigation display body through the connector, and the other end of the HDPE film is surrounded by the surface of the object to be detected through another connector.

[0013] Furthermore, the connecting piece is made of adhesive, magnet, adhesive tape or Velcro.

[0014] Furthermore, it also includes a control circuit, a display screen, buttons and a main switch arranged on the smoke display instrument body.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The terms such as "upper", "inner", "middle", "left", "right" and "one" cited in this specification are only for the convenience of description, and are not used to limit the scope of the present invention. The change or adjustment of their relative relationship shall also be regarded as the scope of the present invention without substantially changing the technical content.

[0028] The present invention aims at the defects of the traditional 502 fumigation display cabinet being large in size and only being able to be used in the laboratory, and at the same time, the handheld fumigation display instrument in the prior art has high experience requirements and the risk of glue spraying when operating. Therefore, the present invention designs a clippable and detachable portable fumigation display instrument, which is used for a smaller and portable volume and is close to the working principle of the traditional fumigation display cabinet. Compared with the prior art equipment, it has the characteristics of no need for special personnel to hold and wait, visual and controllable changes in heating temperature, humidity and time, flexible use site, wide application objects, small and portable, 502 and water can be added at any time, ready to use and disposable, convenient transportation, low price (cost is about tens of yuan), etc. After the fumigation is completed, the diffusion of 502 glue gas can be prevented, and the pollution to people and the environment can be reduced. It is safe and hygienic, and can be widely used in on-site investigation, inspection and identification, scientific research and other related aspects, reducing manpower and economic burdens, improving work efficiency, and accurate and reliable data, providing strong guarantee for investigation and solving cases or scientific research.

[0029] At the same time, the scope of applicable objects of the present invention is mainly: smooth, non-permeable objects (such as plastic, metal, glass, enamel, ceramic, paint surface, etc.), semi-permeable objects (such as leather, glossy paper, etc.), certain special surfaces (such as human skin, fine-textured textiles, etc.); from the perspective of the material forming the fingerprint, it is also applicable to: dust and sweat mixed fingerprints, layered grease fingerprints, blood and sweat mixed fingerprints, etc., and is almost not restricted by the usage scenarios, and can also be used to display fingerprints formed by climbing high places, etc.

[0030] The structure and working principle of the clippable and detachable portable smoke display device of the present invention are introduced as follows:

[0031] A portable smoke display device that can be clipped and detached, such as Figures 1 to 4As shown, it includes a smoke display instrument body 1, a liquid suspension part, a fixing frame 18, and a cover body 3. An open end 11 is provided at one end of the smoke display instrument body 1, and a temperature and humidity sensor and a temperature adjustment device (not shown) are provided in the open end 11; the liquid suspension part is movably arranged in the open end 11 of the smoke display instrument body 1, and is used to contain 502 glue or a mixture of 502 glue and water (whether water is added is mainly determined by the detected ambient humidity); the fixing frame 18 is arranged on the surface of the smoke display instrument body 1; the cover body 3 is detachably arranged at the open end 11 of the smoke display instrument body 1, and the other end of the cover body 3 away from the smoke display instrument body 1 surrounds the object to be measured.

[0032] Therefore, the present invention replaces the previous hand-held operation mode by setting a fixing frame 18 on the smoke display instrument body 1 to fix the smoke display instrument at a desired position through the fixing frame 18. During the smoke display process, a liquid suspension member is movably set in the open end 11 of the smoke display instrument body 1 to contain 502 glue or a mixture of 502 glue and water, and the liquid suspension frame is heated by starting the temperature and humidity adjustment member to vaporize and spray out the 502 glue or the mixture of 502 glue and water, so that the traces on the surface of the object can be smoked in time in a relatively sealed environment, and the temperature sensor can play a role in real-time detection of ambient temperature and humidity, so the user can adjust the heating temperature of the heater according to the temperature, and add water to the liquid suspension frame in time according to the ambient humidity to maintain relative humidity, so that the smoke display instrument body 1 can be better maintained in a good working environment. The detachable connection between the cover body 3 and the fumigation display instrument body 1 mainly depends on factors such as whether the currently detected object is in a relatively closed environment. When the object is not in a relatively closed environment, the cover body 3 can be set to put the object in a relatively closed environment, thereby facilitating the improvement of the fumigation display effect on the object. Compared with the traditional 502 fumigation display cabinet and handheld fumigation display instrument in the prior art, the present invention can overcome the defects of usage scenarios and hand-held risks, and does not require special personnel to hold it for use. The temperature and humidity are adjusted by the temperature regulating device to keep the fumigation display instrument in a good working environment. At the same time, the cover body 3 can reduce the diffusion of 502 glue gas during use, reducing pollution to people and the environment. Therefore, the fumigation display instrument of the present invention can be widely used in field investigation, inspection and identification, scientific research and other related aspects, reducing manpower and economic burdens, improving work efficiency, and the data is accurate and reliable, providing strong guarantees for investigation and solving cases or scientific research.

[0033] In this embodiment, in order to realize the control of temperature, humidity, time timing or delay, the smoke display device of the present invention also includes a control circuit (not shown) arranged on the smoke display device body 1, a display screen 14, a button 15 and a main switch 16, wherein the control circuit is placed inside the smoke display device body 1, and the control circuit, the display screen 14, the button 15, the main switch 16, the temperature and humidity sensor 13, and the temperature adjustment device are all electrically connected to the control circuit. The control circuit has a clock circuit, which mainly serves to realize the display and automatic timing delay functions. The display screen 14 is used to display the temperature and humidity sensed by the temperature and humidity sensor 13. The display screen 14 is also used to messenger the time of the clock circuit, and the button 15 is used to control the temperature adjustment device to adjust the temperature and humidity. The main switch 16 is arranged at the bottom of the smoke display device body 1 to control the opening and closing of the control circuit.

[0034] In practice, the display screen 14 and the button 15 are integrated into one, and are arranged on the outer shell of the smoke display instrument body 1. There are three buttons 15 on the display screen 14, and they are arranged in a straight line. The display content on the display screen 14 is "temperature, power, humidity, usage timer, and timing timer". The timing display starts when the button 15 is turned on. The maximum time for one use is 30 minutes. The timing can be set to 5 minutes per gear, up to 30 minutes, and the maximum time for one smoke display is 30 minutes. According to the on-site environment, the surface of the smoke display instrument body 1 is not hot and can be turned on for the next use after an interval of 5 minutes. The temperature control can be adjusted from 0℃ to 80℃, and a gear is set every 10℃. The button 15 can adjust the controllable temperature left and right. The above data can be used for fixed records by writing or taking pictures. If multiple functions and multiple data are integrated in the future, it can be considered to export information to a computer or mobile phone by TypeC capacitor transmission.

[0035] In this embodiment, in order to realize the function of adjusting temperature and humidity of the temperature and humidity regulating part. The shell material of the smoke display instrument body 1 is selected from heat-resistant plastic and silicone. The heat-resistant silicone is located at one-third of the opening end 11 of the smoke display instrument body 1. The heat-resistant plastic can increase friction and improve the hand feel comfort. The shell connection of the smoke display instrument body 1 is designed with a sealing ring to prevent moisture and water. The temperature and humidity regulating part adopts a heater and an overheating protector arranged in the smoke display instrument body 1. The heater adopts a nickel-chromium wire heating core for heating. The conventional nickel-chromium wire heating core heats up quickly and evenly, and has high durability. It is equipped with a temperature overload protector for real-time protection. The overheating protector can monitor the temperature of the working environment in real time, and trigger the function of adjusting the temperature of the heater, and can also play a moisture-proof effect; at the same time, the smoke display instrument body 1 is provided with a number of heat dissipation holes 19 to ensure air flow and long-term work without getting hot, thereby ensuring service life and safety.

[0036] In addition, regarding the charging structure of the smoke display device body 1, a charging capacitor device and an exposed main switch 16 are provided inside the smoke display device body 1. The main switch 16 is used to control the on and off of the battery of the smoke display device of the present invention. The charging port adopts a Type C interface. The Type C capacitor can provide a stable current by storing and releasing charges to ensure the normal operation of the heater.

[0037] In this embodiment, Figures 1 to 5 As shown, in order to make the liquid suspension part movably mounted on the open end 11 of the smoke display body 1, when the smoke display body is installed and fixed at any angle, the liquid suspension part can maintain a relatively horizontal state to reduce the situation that the 502 glue or the mixture of 502 glue and water contained therein is dumped and leaked. Among them, the liquid suspension part adopts a heating cup 2, and the opposite sides of the inner circumference of the open end 11 of the smoke display body 1 are protruded with hanging shafts 12, and the opposite sides of the outer circumference of the cup mouth of the heating cup 2 are provided with hanging ears 21, and the hanging ears 21 are crescent-shaped. The two hanging ears 21 of the heating cup 2 are respectively suspended on the two hanging shafts 12. The heating cup 2 is supported on the hanging shaft 12 by the hanging ears 21 to realize rotation, so that the heating cup 2 is always kept in a relatively horizontal state to prevent the liquid from dumping, and at the same time, it is convenient to clean the heating cup 2 after disassembly.

[0038] At the same time, the opening end 11 of the smoke display body 1 of the present invention can be designed in two ways. One is that the opening end 11 is a single-layer structure. The single-layer structure of the opening end 11 of the smoke display body 1 is made of stainless steel material, which is directly connected to the heater of the temperature and humidity adjustment component, so that the heater can be used to heat the opening end 11 of the single-layer structure, and then indirectly heat the heating cup 2. The other is that the opening end 11 is a double-layer structure. This double-layer structure is based on the single-layer structure, and a high-temperature resistant heat-insulating layer is added to the surface of the single-layer structure. The high-temperature resistant heat-insulating layer can be made of silicone material to prevent overheating and scalding.

[0039] In this embodiment, Figure 6 As shown, in order to facilitate direct observation of the amount of 502 glue and / or water added; the present invention also designs the heating cup 2 as follows: a partition 22 is provided in the heating cup 2, and the partition 22 forms two partition grooves 23 in the cup cavity of the heating cup 2; one of the partition grooves 23 is used for adding 502 glue, and the other partition groove 23 is used for adding water, so that the user can intuitively observe the amount of addition, and then facilitate timely adjustment of the amount.

[0040] In this embodiment, in order to facilitate timely and convenient cleaning of the residue in the heating cup 2 after identification, a disposable tin paper cup (not shown) is arranged in the cup cavity or the partition groove 23 of the heating cup 2. The disposable tin paper cup can be arbitrarily pinched into any shape (the shape mainly depends on the shape of the partition groove 23). The disposable tin paper cup is used to hold 502 glue, water or a mixture of 502 glue and water. Therefore, when the object is identified or tested by the fumigation display instrument, the disposable tin paper cup on the heating cup 2 can be directly taken out and discarded without cleaning the inside of the heating cup 2, so that the inside of the heating cup 2 is always kept clean and convenient for the next test or identification, which has the advantages of simple and efficient operation.

[0041] In this embodiment, Figures 1 to 4 As shown, the fixing frame 18 is arranged at the front side of the smoke display instrument body 1 near the opening end 11, and the fixing frame 18 adopts a U-shaped hook, and the two ends of the U-shaped hook are respectively rotatably mounted on the two sides of the smoke display instrument body 1, and the U-shaped hook can realize a 90° rotation; a storage groove 17 is provided on the surface of the smoke display instrument body 1, and when the U-shaped hook is turned toward the smoke display instrument body 1, the U-shaped hook is partially stored in the storage groove 17. Therefore, when in use, the smoke display instrument body 1 can be kept relatively fixed by hanging the U-shaped hook at the corresponding position, so as to facilitate the generation of gas colloid through the heating cup 2 on the smoke display instrument body 1, thereby realizing the function of identifying or detecting the corresponding object; at the same time, when not in use, the U-shaped hook can be stored in the storage groove 17 to save the use space.

[0042] like Figure 7 As shown, the smoke display device of the present invention further includes an external bracket 4, and the external bracket 4 is in a relatively separated state from the smoke display device body 1. The use of the external bracket 4 mainly depends on whether there is a situation in which the smoke display device body 1 can be hung in the use scenario. When there is no situation in which the smoke display device body 1 can be hung, the smoke display device body 1 can be fixed or hung with the help of the external bracket 4, thereby facilitating further identification or detection operations. The external bracket 4 of the present invention includes a support base 41, and an inclined plate 42 is provided on the support base 41. The inclined plate 42 is provided with a groove 43 for the smoke display device body 1 to be placed, and the inclined plate 42 is provided with a connecting nail 44, and a U-shaped hook is hung on the connecting nail 44.

[0043] In this implementation, if Figure 4 As shown, the cover body 3 is made of colorless, transparent and environmentally friendly HDPE film, which is arranged on the smoke display instrument body 1 to form the cover body 3. Connectors 31 are arranged at both ends of the HDPE film. One end of the HDPE film is arranged on the edge of the open end 11 of the smoke display instrument body 1 through the connector 31, and the other end of the HDPE film is surrounded by the surface of the object to be detected through another connector 31.

[0044] It should be noted that when the HDPE film is surrounded by the surface of the object to be detected through the connecting piece 31, it is usually not restricted by the surface condition or shape of the object. The object can be partially surrounded and then fumigated (that is, the above-mentioned identification or detection method), or the object can be surrounded or wrapped as a whole and then fumigated. Therefore, no matter whether the object is large or small in volume, the required fumigation surface can be partially surrounded and sealed and then fumigated. The core of this is that the HDPE film can be cut into large or small areas for use, and can be directly discarded after use, so it has the function of easy operation.

[0045] Among them, the HDPE film has good chemical stability, good corrosion resistance, light texture, easy to carry, install and use, waterproof and dustproof, changeable shape, good transparency, and can conveniently observe the trace appearance of the object during the fumigation process without frequently opening the dust cover for inspection. It also plays a role in isolating 502 gas colloids and reducing human inhalation and environmental pollution. After the fumigation work is completed, the two ends of the cover body 3 can be tied up by hand and discarded. HDPE material is a recyclable plastic that can be recycled and reused through recycling and reprocessing, meets environmental protection requirements, is low in price, and reduces financial pressure.

[0046] In this embodiment, the connecting member 31 can be made of adhesive, magnet, adhesive tape or Velcro. The specific structure of the connecting member 31 is described in detail below.

[0047] When the connecting piece 31 is made of adhesive, the adhesive can be an adhesive sticker (i.e., double-sided tape). When in use, one end of the HDPE film is adhered to the outer peripheral surface of the open end 11 of the fumigation display instrument body 1 through the adhesive sticker, and the other end is adhered to the entire or partial periphery of the object to be detected through the adhesive sticker, so that the HDPE film is adhered to form a corresponding closed cover body 3 space, which is convenient for fumigating the object surface.

[0048] When the connecting piece 31 adopts a magnet, a metal ring can be set in advance on the outer peripheral surface of the open end 11 of the fumigation display body 1, and a metal sheet can be set on the partial or whole outer peripheral surface of the object to be inspected, and then magnetic sheets can be set on both ends of the HDPE film. When in use, the magnetic sheet at one end of the HDPE film is magnetically attracted to the metal ring, and the magnetic sheet at the other end is magnetically attracted to the metal sheet on the surface of the object to be inspected, so that the HDPE film is adhered to form a corresponding closed cover body 3 space, which is convenient for fumigating the object surface.

[0049] When the connecting piece 31 is made of glue (i.e., single-sided tape), one end of the HDPE film is wrapped around the outer peripheral surface of the open end 11 of the fumigation display instrument body 1, and then fixed with adhesive tape, while the other end of the HDPE film is also surrounded by the entire or partial periphery of the object to be detected, and then fixed with adhesive tape, so that the HDPE film is pasted to form a corresponding closed cover body 3 space, which is convenient for fumigating the object surface.

[0050] When the connecting piece 31 adopts Velcro, the Velcro includes a first surface and a second surface. The first surface is arranged on the outer peripheral surface of the opening end 11 of the fumigation display instrument body 1 and the overall or partial periphery of the detected object, and the second surface is arranged on both ends of the HDPE film respectively. When in use, one end of the HDPE film is adhered to the first surface of the outer peripheral surface of the opening end 11 of the fumigation display instrument body 1 through the second surface, and the other end of the HDPE film is adhered to the first surface of the overall or partial periphery of the detected object through the second surface, so that the HDPE film is adhered to form a corresponding closed cover body 3 space, which is convenient for fumigating the object surface.

[0051] Based on the above introduction to the overall structure of a portable, clippable and detachable smoke display device of the present invention, the working principle of the smoke display device in two states with or without a cover 3 is described below:

[0052] 1) Regarding the use without the cover body 3, the object is in a relatively closed space:

[0053] like Figures 1 to 3 As shown, by putting 502 glue in a disposable tin paper cup and putting it into the heating cup 2 of the liquid suspension device, the humidity can be increased as needed by the environment. When increasing the humidity, the 502 glue and water can be respectively put into the disposable tin paper cups and put into the two dividing grooves 23 of the heating cup 2. The disposable tin paper cups are used for the convenience of disposable after use; turn on the main switch 16 of the fumigation display body 1, the temperature of the heater increases, and the data sensed by the temperature and humidity sensor 13 of the liquid suspension device can be transmitted and controlled using the display screen 14 and the button 15, and the fumigation process is adjusted by controlling the temperature and time. The content of the display screen 14 is "temperature, power, humidity, usage timer, timer timer". The timer starts to display when the machine is turned on. The maximum time for one use is 30 minutes. The timer is set to 5 minutes per gear, up to 30 minutes. The maximum time for fumigation is 30 minutes. According to the on-site environment, the machine body can be turned on for the next use after a 5-minute interval if it is not hot. The temperature control can be adjusted from 0℃ to 80℃, with a gear set every 10℃. The button 15 can adjust the temperature. The above data can be recorded in writing or taking pictures. The fumigation process is 5-30 minutes. After use, turn off the main switch 16 of the fumigation display body 1, discard the disposable tin paper cup or clean the semicircular heating cup 2, and the fixing frame 18 can be stored in the fumigation display body.

[0054] 2) Regarding the use with the cover 3, the object is in a non-enclosed space:
