Environmental efficient intelligent spray type ozone disinfection device
Description: Objective: We want to invent a low cost, simple to obtain raw materials, convenient and fast disinfection device. Our device only needs to be charged, fill it with water, and it will automatically start generating ozone. The ozone will then combine with the water to produce ozonated water. Ozone is highly toxic and is cheap to create through ionization. Unlike the production of alcohol, i.e., a certain amount of ethanol to water, which is very inexpensive. Manufacturing Solution: We designed an ozone spray disinfection unit. We expected a sterilization unit that would kill without any dead ends. The disinfection unit is divided into a disinfection zone and an inlet for adding raw materials. The upper part is the disinfection zone. The top part is the disinfection zone. When you put your hand into the sensing area, the fogging device will activate the disinfection. The middle part is the raw material addition portal. Only a sufficient amount of water is needed for the raw materials. The disinfection unit consists of an ozone generation and transportation system, an electrical control system, and a fogging system. The upper part allows the hand to reach in to disinfect, while the lower part is where the device is placed; the middle of the upper and lower part will run through and hold the nebulizer. We will use a small nebulizer with small holes at the bottom for the cotton swab to absorb water and transport it through the pipe to the spout. Since ozone needs to react with water to have disinfection effect, we will also place a closed box under the nebulizer. The mouth of the box wraps around the part of the nebulizer that has small holes. Because the water in the box will be absorbed by the cotton swab of the nebulizer in order to spray out. Then there will be two pipes on both sides of the box, one pipe connected to the ozone that is created, and the other pipe connected to the water supply pipe. Small humidifier connected to infrared sensor to open the device, just put your hand into the sensor area, the atomization device will naturally start.
Design Background. In this time of rampant epidemic, governments around the world have implemented a series of prevention and control measures. After several months of prevention and control efforts, the virus slowly but not completely receded. Instead, the epidemics in foreign countries have become severe. From these things, the transmission rate of the virus as well as the infection rate is extremely high. As a result of the epidemic, there was a widespread spread of bacteria. The human body is invaded by the bacteria, making it sick and uncomfortable. In severe cases, death can occur. Therefore, since the epidemic, people travel with disinfectant things to go out. For example, alcohol hand sanitizers and alcohol sprays and other disinfection tools. The demand for hand sanitizer and alcohol sanitizer has increased. And the cost of alcohol disinfectants is too high compared to developing countries. Nowadays, people have to wash their hands with alcohol disinfectant every time they do nucleic acid health care workers, which in turn greatly increases the cost of use.

Ozone disinfection principle: Ozone is a strong oxidant and the sterilization process is a biochemical oxidation reaction. Its disinfection principles are. 1、Ozone can oxidize and decompose the enzymes needed for glucose inside bacteria, which makes bacteria inactivate and die. 2. Ozone acts directly with bacteria and viruses, destroying their organelles and DNA and RNA, so that the metabolism of bacteria is damaged, resulting in bacterial death. 3、Ozone penetrates through the cell membrane tissue and invades into the cell, acting on the lipoproteins of the outer membrane and the internal lipopolysaccharide, causing the bacteria to undergo permeability distortion and lysis and death. Innovative: This is a hand sanitizer with a new concept. It has a faster, more efficient, and more comprehensive disinfection capability than traditional alcohol sanitizers. The disinfection material used in this handwasher is different from the traditional alcohol disinfection machine. The raw material used to disinfect the handwasher is ozone water vaporized and then made into a disinfectant spray. This ozone water and the traditional alcohol disinfectant compared to the ozone water has a strong oxidizing properties, is a wide range of disinfectant germicidal agent. It can kill bacteria and viruses on the surface of objects. Ozone water has a strong sterilizing effect on various pathogenic microorganisms, which is equivalent to the oxidizing power of fluorine. But compared to fluorine gas, it is far less harmful to humans. Plus it is a gas disinfectant spray, which is much stronger than the traditional liquid disinfectant coverage. While the liquid disinfectant can still only slowly cover the area to be disinfected through liquid flow, the disinfectant gas has completely enveloped the area to be disinfected. Compared to the material consumption of traditional alcohol disinfectant, the only materials to be used for ozone disinfection are electricity and the addition of water, which allows for continuous disinfection. There is no need to replenish specialized disinfection materials because they run out. It provides a great help to save materials.
