Description

Technical Field

[0001] The invention relates to the field of disinfection, sterilization and detection, in particular to a plasma flashlight based on dielectric barrier discharge (DBD) flexible plasma sterilization and detection integration. Background Art

[0002] People's lives are inseparable from food, clothing, housing and transportation. Bacteria are everywhere in life, especially bacteria are pathogens of many diseases and are invisible to the naked eye, which has a great impact on people's lives. In order to sterilize and disinfect, people have adopted a variety of technical means such as ultraviolet disinfection, high temperature disinfection and chemical reagent disinfection, but these technologies have their own shortcomings. Ultraviolet rays are harmful to the human body; high temperature will cause the loss of nutrients in food, and it is not suitable for non-thermosensitive, moisture-resistant and high-temperature appliances; chemical reagents are highly corrosive, and some reagents contain carcinogens, which are very dangerous to use. Now electronic payment has become the mainstream of payment, but paper money has not withdrawn from the trading market and is still used in large shopping malls, supermarkets and hospitals. Paper money has been circulated by many people, and the bacteria it carries are countless, and the existence of counterfeit money also makes people distressed. Although there are many banknote detectors on the market now, they are not suitable for home shopping, small stores or grocery stores in terms of price and convenience, and most banknote detectors have a single function. As people's pursuit of beauty becomes higher and higher, fluorescent agents have gradually penetrated into all aspects of our lives, such as textiles, papermaking, laundry detergent, plastics, etc. Excessive levels of fluorescent agents can cause great harm to the human body, especially to infants. Therefore, the detection of fluorescent agents in baby items, underwear and cosmetics has become a concern for most people.

[0003] Most of the fluorescent detection pens in the existing technology have single functions. Plasma sterilization technology, as a new generation of high-tech sterilization technology, has the advantages of room temperature, time saving, wide range of use, non-toxicity, and environmental protection. However, most products are large in size, not easy to carry, and expensive. Summary of the invention

[0004] The purpose of the present invention is to provide a plasma flashlight with integrated sterilization and detection in view of the deficiencies in the prior art. The invention adopts dielectric barrier discharge (DBD) flexible plasma sterilization and disinfection technology, and sets a plasma actuator on the lamp head of the flashlight. The active ions released during the plasma generation process and the high thermal energy of the rich ultraviolet rays are used to improve the efficacy of the interaction with microbial proteins and nucleic acid substances, so that the microorganisms are killed in a very short time, thereby achieving the purpose of sterilizing the equipment. The invention integrates the functions of sterilization and disinfection, fluorescent agent detection and banknote verification, has a simple structure, a small size, is easy to carry, is easy to use, has a low cost, and has a wide range of applications. The number of plasma actuators used can be adjusted according to the area of ​​the irradiated object, and has the advantages of energy saving and environmental protection.

[0005] The specific technical scheme for achieving the purpose of the present invention is: a plasma flashlight integrated with sterilization and detection, comprising an LED lamp and a battery arranged in the flashlight, characterized in that the flashlight is provided with a plasma structure in which three plasma actuators are electrically connected to a boost transformer and an inverter, and the plasma actuator is a funnel-shaped plasma made of a composite material of an ITO flexible transparent conductive layer and a flexible transparent dielectric insulating layer; the three plasma actuators are arranged outside the LED lamp in a three-layer stack, and the diameter of the third plasma actuator is 1 / 2 of the diameter of the second plasma actuator, and the diameter of the second plasma actuator is 1 / 2 of the diameter of the first plasma actuator; the LED lamp is embedded in the third plasma actuator and connected to the battery by a fourth switch; the first plasma actuator is connected in series with the boost transformer and the inverter in sequence through the first wiring hole through the first switch; the second plasma actuator is connected in series with the boost transformer and the inverter in sequence through the second wiring hole through the second switch; the third plasma actuator is connected in series with the boost transformer and the inverter in sequence through the third wiring hole through the third switch; the boost transformer and the inverter are powered by a battery.

[0006] The ITO flexible transparent conductive layer is a positive / negative electrode compounded on the inner and outer surfaces of the flexible transparent dielectric insulating layer; the flexible transparent dielectric insulating layer is an intermediate barrier layer.

[0007] The three plasma actuators are arranged in three layers of overlapping with equal spacing.

[0008] The LED lamp is a white light source used for banknote verification and fluorescent agent detection, and its wavelength is 365nm.

[0009] The first switch, the second switch and the third switch can adjust the number of plasma actuators used according to the area of ​​the irradiated object.

[0010] Compared with the prior art, the present invention integrates sterilization and disinfection, banknote verification and fluorescent agent detection, and can adjust the number of plasma actuators used according to the area of ​​the irradiated object. It is easy to use, energy-saving and environmentally friendly, has a simple structure, a small size, and is easy to carry. It can be widely used in sterilization and disinfection and fluorescent agent detection in various occasions such as large shopping malls, hospitals or homes. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] See also Figure 3 The plasma actuator 6 is a funnel-shaped plasma made of a composite material of an ITO flexible transparent conductive layer 16 and a flexible transparent dielectric insulating layer 17; the ITO flexible transparent conductive layer 16 is a positive / negative electrode composited on the inner and outer surfaces of the flexible transparent dielectric insulating layer 17; the flexible transparent dielectric insulating layer 17 is an intermediate barrier layer.

[0016] See also Figure 1 to Figure 3The present invention works as follows: the battery 15 can obtain 10kv AC through the inverter 13 and the step-up transformer 14, and is connected in parallel to the first plasma actuator 6-1, the second plasma actuator 6-2 and the third plasma actuator 6-3 controlled by the first switch 2, the second switch 3 and the third switch 4, respectively. The plasma actuator 6 adopts a DBD structure. When a high voltage is connected, the surface of the ITO electrode 16 is micro-discharged to excite plasma in the surrounding air. Since the three plasma actuators 6 are funnel-shaped and have a layered embedded structure, the excited plasma can be gathered in the funnel and at the funnel mouth, making the sterilization more efficient and more comprehensive. The light source wavelength of the LED lamp 9 is 365nm, which can not only detect the content of fluorescent agents in clothing, facial masks or baby products, but also can be used for banknote verification. The plasma actuator 6 is made of transparent material, which ensures the normal use of the LED lamp 9 as lighting. Since the ultraviolet rays and a large amount of highly active substances (O3) generated by the plasma actuator 6 achieve the effect of sterilization and disinfection by contacting the treated object, sterilization and disinfection can also be performed at room temperature. The first switch 2, the second switch 3 and the third switch 4 are used to control the first plasma actuator 6-1, the second plasma actuator 6-2, the third plasma actuator 6-3 and the LED lamp 9 respectively. The number of plasmas to be used is determined according to the area of ​​the irradiated object, thereby achieving energy saving and environmental protection.
