Abstract

A high-voltage plasma sterilization tank refers to the use of a high-voltage plasma generating device to ionize the neutral air molecules in the tank through the high-voltage plasma device to ionize the uncharged air molecules. The air molecules will lose part of their surroundings. The outermost electrons rotating in the atomic nucleus ionize the air in the tank. The electrons that escape from the atomic nucleus are called free electrons and are negatively charged. When the free electrons combine with other neutral gas molecules, they form negatively charged air negative oxygen ions. Negative oxygen ions can interfere with the structure and function of bacteria, thereby inhibiting their growth and reproduction, thereby enabling the storage tank to achieve antibacterial and mold removal effects.

Description

High voltage plasma sterilization tank

This creation is related to storage tanks, especially a high-pressure plasma sterilization tank.

Press, a food storage tank is a container used to preserve food, especially a vacuum food storage tank. Its principle is to create a sealed environment, extract the internal air, reduce the internal pressure, thereby preventing oxygen from entering the container, thereby prolonging the Food freshness and shelf life. Vacuum food storage jars are an effective method of food storage, but even after sealing, mold still exists in the jar. Mold is a fungal microorganism. Mold needs organic matter to grow and reproduce. These organic matter can be food, wood, Paper, cloth, etc., when these organic materials are moist and at the right temperature, they provide ideal growth conditions; commercially available vacuum food storage jars only extract the air from the jar to prevent oxygen from entering the container, but do not directly store the contents of the container. Mold or bacteria must be eliminated. Therefore, once oxygen enters the container, it will still cause the reproduction of mold or bacteria, which will affect the quality of the food and even be harmful to health. When the vacuum food storage tank is opened and you want to store food again, It is necessary to pump the air again to eliminate the air in the tank, so it is extremely inconvenient to use.

Therefore, after observing the above shortcomings, the creator of this case believed that there was a need to improve the existing food storage cans, and this invention came into being.

The circuit board is installed in the receiving groove on the body. The circuit board includes a main control circuit and a negative high-voltage circuit. The negative high-voltage circuit can provide the negative high voltage of the high-voltage discharge needle plate; a rechargeable battery is It is disposed in the accommodation slot on the main body and is electrically connected to the circuit board to provide the power required by the circulation fan and the circuit board.

In order to further understand the structural characteristics, technical means and expected effects of this creation, the working principle of this creation is described here. I believe that this will lead to a more in-depth and specific understanding of this creation, as follows: Please refer to Figure 5, which is a circuit block diagram of a preferred embodiment of the invention. When the invention operates by pressing the start switch 216, since the bottom plate 23 is provided with an air inlet 231 and through the body 21 The air duct is formed, so the air in the tank 10 can be sucked into the tank lid 20 through the built-in circulation fan 31, and the air can be introduced into the high-pressure air duct through the closed air duct cavity formed by the air guide covers 311. The discharge needle plate 32 is finally released from the air outlet 232 of the bottom plate 23. Since the high-voltage discharge needle plate 32 generates a fixed frequency switching signal by the MCU and adjusts the output high voltage voltage in a PWM manner, through isolation The MOS tube below the transformer converts DC 5V into AC high voltage, and then uses a multi-stage voltage doubling method to generate high-voltage plasma at the tip of the high-voltage discharge needle plate 32. The high-voltage discharge needle plate 32 provides a discharge path, and then Generate high concentration of nano-scale negative oxygen ions, and high-voltage plasma generates high concentrations of negative oxygen ions. Since negative oxygen ions have negative charges, and the surface of bacteria usually has positive charges, this leads to the interaction between negative oxygen ions and bacteria. The charge interaction between them causes them to adhere to the surface of bacteria. This will interfere with the structure and function of bacteria, thereby inhibiting their growth and reproduction. Therefore, the circulation fan 31 continuously circulates the air in the tank through the air duct formed in the body 21 and the high-voltage discharge needle plate 32, and the high-voltage plasma is The high-concentration nano-negative oxygen ions produced will coat and destroy the cell walls of the bacteria in the tank. The high-concentration negative oxygen ions generated by the high-voltage plasma will eliminate the coating and destruction of bacteria in the air in the tank. In this way, by continuously circulating and sterilizing the air in the tank, the bacteria in the tank are eliminated to prevent the growth of mold in the tank, thereby achieving the sterilization effect.

After actual testing by the Guangdong Provincial Microbiological Testing Center in Mainland China, this product has an antibacterial rate of up to 99% against mold and other bacteria.

It is worth mentioning that the MCU of this device is also responsible for the detection and protection control of battery overcharge, overdischarge, and overtemperature. In addition, in order to extend the battery life, this device uses The MCU performs intermittent control on the high-voltage discharge needle plate 32 and the circulation fan 31 to achieve long-term use of the battery. If the battery is low in power, the buzzer and the battery indicator light 217 will simultaneously sound and flash red.

To sum up, this invention has excellent practicality among similar products. At the same time, after searching the technical information about this type of structure at home and abroad, no similar structure has been found in the literature. Therefore, This invention has indeed met the requirements for a new patent, and an application must be filed in accordance with the law.
