Although the plasma jet disinfection technology has great advantages, there are still many problems in the existing low-temperature plasma emission device technology with positioning and environmental recognition functions, mainly reflected in:

The invention uses nano-materials as discharge electrodes to generate a low-temperature plasma ion source through dielectric barrier discharge, and proposes a technique similar to "inner closed plasma jetting". Different from the existing internal injection technology, the breakthrough uses nano-scale/micro-scale conductive fibers (nano-column/micro-column) to use pulse voltage for dielectric barrier discharge to release plasma when it is necessary to use plasma, so that Have a disinfecting effect.

Technical points of this invention patent:

(1) Use low temperature plasma sterilization technology

Low-temperature plasma sterilization technology has spectral sterilization characteristics for bacteria and fungi, high sterilization efficiency, no chemical residues, no drug resistance, low temperature, good diffusion and permeability.

Compared with other low-temperature plasma discharge technologies, the low-temperature plasma generator using dielectric barrier discharge (DBD) has a smaller equipment size, is easy to carry, and can be hand-held to complete disinfection and sterilization.

(3) Formation of plasma

Plasma is produced by using a high-frequency and high-voltage plasma generator, that is, under the condition of high-frequency voltage, the air is avalanche into plasma by means of dielectric barrier discharge.

(4) With positioning and identification functions

Now is the era of rapid data development, the national Internet is no longer the future, using data exchange technology for positioning and identification, and transmission, can carry out the most accurate positioning and identification transmission at the most needed moment, so as to guard the environment and guard healthy.

(1) The sterilization device does not need consumables, is low in cost, safe and environmentally friendly, and highly efficient in sterilization.

Adopting low-temperature plasma sterilization technology, no need to use chemicals, no consumables, and low cost, the plasma enters the inner space of the humidifier through five electric ceramic rods, and diffuses through the air outlet, and there is no dead angle for sterilization. , due to the directionality of light, simple ultraviolet sterilization is prone to sterilizing dead angles, and the sterilization effect on fungi is poor; the main active ingredients of low-temperature plasma include charged particles, active particles and free radicals (oxygen atoms, hydroxyl groups, Active oxygen, active nitrogen), high-energy ultraviolet rays in VUV and UVC bands, thermal effects generated by discharge, bombardment of charged particles, alternating electric fields, have spectral antibacterial effects on bacteria and fungi, no chemical residues after use, and no drug resistance , sterilization effect, environmental protection and safety, while silver ion sterilization will consume silver, and silver ions discharged with water will pollute soil and water sources; the temperature of low-temperature plasma is about 40°C-60°C, low energy consumption, no need to use a lot of water .

(2) It is easier to generate plasma and reduce the quality of equipment.

Due to the principle of dielectric barrier discharge technology, micro-nano columnar materials are coated inside the closed wave-transparent material, which makes it easier to generate plasma in the injector; at the same time, using micro-nano materials as discharge electrodes greatly reduces the discharge voltage and reduces the volume of the discharge device. , quality, power, etc. are greatly reduced, reducing the load on the device.

Working principle, when in use, the plasma is introduced into the plasma storage container 5 through the plasma introduction port 8, the liquid inlet pipe 36 is connected with the disinfectant, the atomizing pump 10 is started to atomize the disinfectant into the low-temperature plasma launch port 1, and through The low-temperature plasma launch port 1 ejects the disinfectant gas and liquid, the servo motor 11 drives the first hypotenuse cylinder 12 to rotate, the first hypotenuse cylinder 12 squeezes the second hypotenuse cylinder 13 to move, and the second hypotenuse cylinder 13 drives the piston rod 14 and the piston 17 move, and the pulling force of the tension spring 16 makes the piston 17 reciprocally slide in the air cylinder 15, and the gas enters the gas through the one-way intake valve 18, and the gas squeezes the hemispherical sealing plug 20 to leave the fixed ring when the gas is discharged. 19, the gas enters the plasma storage container 5, the plasma is compressed by the air pressure and the sealing gasket 27 leaves the sealing ring 26, and the plasma is introduced into the low-temperature plasma emission port 1, and the atomized disinfection gas and liquid are sprayed out, which can improve the disinfection effect.

The reactive particles carried by the plasma jet can greatly damage the integrity of the cells and eventually lead to the inactivation of microorganisms. This kind of disinfecting ability can be said to be better than most disinfecting products and will not cause any harm to the human body;

By setting the environment recognition module 4 to have the recognition function for the environment, the traditional killing device relies on manpower to judge and kill work, which not only depends on manpower, but also needs to have a certain ability to people, and where in the air needs to be There are unknown judgments in disinfection, which makes it impossible to carry out effective disinfection. By using the recognition of the environment, objects can be effectively identified for judgment and disinfection. Increased efficiency.

By setting the positioning module 2, if in some large places, the concentration of some bacteria or viruses in the air is too dense, it will be combined with the upper and lower computers through the wireless transmission system.
