Description

A kind of environmental physical method disinfection and purification equipment

technical field

The utility model belongs to the technical field of disease prevention and control, in particular to an environmental physical method disinfection and purification equipment.

Background technique

Through cell compounding and evolution over hundreds of millions of years, unicellular organisms have gradually formed three life systems of microorganisms, plants and animals, and established a biosphere of interdependence, mutual restriction and dynamic balance. For hundreds of millions of years, the "war" between viruses and cells for control and survival has never stopped. Humans rely on multiple protection and immune systems to defeat the virus cells will produce specific antibodies to prevent the virus from re-invading and gain immunity. Since cells are the basic structural units that constitute microorganisms, plants and animals, they are easy to become virus adsorbers or virus hosts, and there is the possibility of cross-infection between different species. Therefore, the prevention and control of human and animal infections by viruses or virus-invaded bacteriophages and pathogens is a major and long-lasting issue.

From the perspective of prevention and control methods, cutting off the source of infection is the most commonly used method at present. In view of the existence of droplets, aerosols and contact transmission routes of the virus, in addition to emphasizing personal protection of wearing masks and washing hands frequently, we should strengthen the efficient disinfection and sterilization of the air, ground, objects, supplies and water bodies. The effective means of epidemic spread is also the key link of effective epidemic prevention in the whole society, which directly involves the efficiency, benefit and effect of epidemic prevention and control.

There are defects and deficiencies in the currently used epidemic prevention technology and equipment. For example, the disinfection methods of chemical drugs (such as 84 disinfectant) that are being used in some cities not only consume water, drugs, labor, and time, but also cause harm to people and the environment.

In response to the above problems, the industry has designed a variety of sterilizers that apply physical methods and technologies, which provide people with certain convenience in purifying the air and preventing and controlling germs. Chinese patent 201710384566.2 discloses a consumable-free, maintenance-free medical sterilization air purifier, the core functional component of which is an air sterilization and purification chamber. Disinfection, but there are three main problems with this equipment. First, there are no self-cleaning measures for each layer and ventilation ducts in the purification chamber. The accumulated dust will become a breeding ground for germs and bacteria. If it is not cleaned in time, it will be easily caused in medical places A large number of germs spread; second, the cleaning of dust in the cabin uses a complex high-pressure water pump system, which not only consumes a lot of water, but also the sewage containing germs after cleaning may cause secondary pollution; third, the structure is complex, and the cost of construction and use is high. It is limited to medical use only, and is not suitable for promotion in homes and other places.

Chinese Patent 201420808084.7 discloses a new type of air sterilizer, which mainly uses ultraviolet and ozone to sterilize the air, but there are four major problems. The second is that the machine has no self-cleaning device, and the dust in the machine will become a place for germs to breed and multiply, which is easy to cause the spread of germs; and the environment can cause harm. Fourth, the function of the machine is single, and the use occasions are greatly limited due to the different needs of people.

At present, the most representative product sold in the world is the American Exxon air purifier, which uses ultraviolet sterilization, aluminum alloy mesh, activated carbon layer, cold catalyst layer, antibacterial cotton layer, HEPA layer 5 layers of filtration and negative ion release, Purify the air. But there are two main problems. One is that although it has a certain effect on air purification, the sterilization effect of ultraviolet rays alone on the air is extremely limited, and the required sterilization time is very long; Manual cleaning is not only expensive and complicated to operate, but all filter layers are easy to breed and multiply germs.

To sum up, the equipment currently on the market that uses physical methods to sterilize and purify the air generally uses multi-layer soft material filter layers, which can easily become a new place for the growth and reproduction of germs while filtering germs, and there is a spread of germs. At the same time, the existing patents and equipment lack consumption-free cleaning and self-cleaning functions, so it is difficult to maintain long-term use effects, but it is easy to cause secondary contamination and cross-infection of bacteria, which cannot meet the needs of use. Therefore, the industry needs a multi-functional environmental disinfection and purification equipment with a novel structure, integrating a variety of efficient physical disinfection and purification methods, realizing consumption-free cleaning and self-cleaning effect. The following provides an environmental physical method disinfection and purification equipment and its solution, which solve the above problems in the overall solution and technology.
