Example 1

The plasma disinfection equipment comprises a laser generator and a positive and negative ion separation device; wherein, the laser generated by the laser generator irradiates the water body to generate positive ions and negative ions; the positive and negative ion separation device is used for separating positive ions and negative ions; positive ions separated by the positive and negative ion separation device are output through a first nozzle; the negative ions separated by the positive and negative ion separation device are output through a second nozzle; the first nozzle and the second nozzle are respectively connected with a device.

The laser generator generates laser with proper wavelength to irradiate water body and generate high-density plasma flow, and the plasma flow enters the positive and negative ion separation device to separate positive ions from negative ions, so that different purposes are realized. The positive ions sprayed out from the first nozzle and the negative ions sprayed out from the second nozzle are sprayed into the environment or matched with other equipment for disinfection and sterilization, such as killing new coronavirus, and the like, and has the advantages of remarkable curative effect, high speed and high cost performance. The breathing machine carries positive ions and negative ions to enter the respiratory tract to be disinfected and sterilized, namely, oxygen conveyed by the breathing machine is mixed with the positive ions and the negative ions to enter the respiratory tract, so that the effects of sterilization and sterilization can be realized while the breathing is assisted.

As an optional implementation manner of this embodiment, the system further comprises a power transmission unit, and the power transmission unit is communicated with the water body, the positive and negative ion separation device, the first nozzle or the second nozzle.

The power transmission unit is communicated with any one of the water body, the positive and negative ion separation device, the first nozzle or the second nozzle, and can transmit positive ions or negative ions out; provides power for the transportation of positive ions and negative ions, so that the positive ions, the negative ions and oxygen are mixed and enter the respiratory tract under the action of a respirator.

As an optional implementation manner of this embodiment, the system further includes an optical device, and the laser generated by the laser generator irradiates the water body after passing through the optical device. And the optical device is used for performing alignment and straightening effects on the laser generated by the laser generator so as to excite more positive ions and more negative ions.

As an optional implementation manner of this embodiment, the laser generator includes a laser control unit for controlling the generation of the laser light with different wavelengths. The laser generator can be adjusted to generate laser with different wavelengths, so that more positive ions and negative ions can be conveniently excited. The laser generator can be adjusted to generate laser with different wavelengths, so that more positive ions and negative ions can be conveniently excited. The laser wavelength used to irradiate the water body to excite the plasma jet is preferably two wavelengths of 1.94 microns and 2.96 microns and their adjacent values, or 10.6 microns may be used for the device and equipment size. Lasers with other wavelengths are not excluded, and the determination can be finally carried out by comprehensively considering the optimization in the aspects of cost, size, effect and the like. On the basis of this embodiment, it is conceivable that the laser generator further comprises components such as a laser power supply required for normal operation, and to improve the laser effect produced, the laser generator further comprises optical means for alignment and regulation.

The equipment is a breathing machine, the first nozzle and the second nozzle are respectively connected with the breathing machine, or when the equipment is lung treatment equipment, the first nozzle is connected with the lung treatment equipment, or the equipment is antivirus equipment, and the first nozzle and the second nozzle are respectively connected with the antivirus equipment.

The scheme of using ionized water daughter as medicine for treating coronavirus has obvious curative effect. Since the virus attacks the cells by means of the negative ions carried by the virus, the electronegativity of the virus can be neutralized by inputting a large amount of positive ions into the lung through a lung treatment device. As a result, the virus loses the function of attacking cells, that is, the virus has a possibility of greatly reducing the ability of attacking cells by using the principle of combining positive ions and negative ions of virions.

1. Partial discussion of the electronegativity of viruses

RNA has a phosphoribosyl skeleton and bases, but bases are poor in hydrophilicity, so that the phosphoribosyl skeleton is generally exposed on the surface of a molecule, the bases are wrapped inside and are stabilized by base stacking force (in fact, pi-pi delocalized electron interaction) and hydrogen bonds and are not easy to ionize, and the phosphate groups are exposed on the surface of the molecule and are negatively charged, so that the whole RNA molecule is negatively charged.

2. A laser can be used to cleave clusters of water molecules. By using the resonance principle, laser with proper wavelength can crack huge water molecule groups with high efficiency. For example, a 1.94 micron or 2.96 micron laser is used to treat the body of water. By laser processing, it is possible to ionize water molecular clusters of huge molecular weight and generate plasma with high efficiency.

3. The plasma thus generated can be decomposed and form two ion flows, positive and negative.

4. The presence in the plasma is essentially of bare ions and electrons, as well as atomic molecules excited by electron collisions. Because of the collision process to break chemical bonds, we see a large number of individual atoms that are extremely chemically reactive, especially atoms like F can corrode almost all substances. Furthermore, even if the elements are chemically inert, they have the ability to attack physically, i.e. ions hit the solid surface, knock atoms out of the solid surface directly, or activate chemical bonds of the solid, catalyzing various chemical reactions.

5. The plasma has strong chemical activity, so that the biological properties of the virus can be greatly changed, particularly, positive ions in the plasma can neutralize the negative electricity of a virus shell, the capability of the virus to attack cells is reduced, and the virus is killed.

Summarizing the above arguments, the laser decomposes the water molecule groups to a great extent, obtaining a plasma stream (up to several billion plasma pairs per cubic centimeter) with a very high ion content; the positive ions are utilized to treat the lung of a virus patient or used for treating the virus environment, and the positive ions neutralize the negative charges carried by the virus shell in the contact of the positive ions and the virosome in the process, so that the virus attack capacity can be greatly reduced, and the device can receive remarkable curative effect on most virus patients and extremely good environment disinfection effect.
