Environmental physical method sterilization and purification equipment

Abstract

The invention relates to environmental physical method disinfection and purification equipment, and belongs to the technical field of disease prevention and control. The environmental physical methoddisinfection and purification equipment at least comprises a fan unit, a control panel, a high-voltage unit, an ultraviolet unit, a nanometer-silver material unit, an ozone device, a surface disinfection unit, a control circuit unit and a chassis. Ambient air is sucked in by a fan unit, passes through a primary filter screen arranged at a front end ventilating opening of the fan unit, is then subjected to stage-by-stage physical disinfection and purification through the high-voltage unit, the ultraviolet unit, the nanometer-silver material unit, the ozone device and the surface disinfection unit, is then discharged through four-side air doors arranged on the chassis to form rotating airflow, and is then continuously introduced by the fan unit to constantly perform circulating disinfectionand purification. The surface disinfection unit is connected with an external air opening formed in the chassis to carry out physical disinfection treatment on an object. The environmental physical method disinfection and purification equipment has the main functions of high-efficiency sterilization with respect to various germs, air purification, device self-cleaning and automatic cleaning, and can effectively prevent germs from breeding and avoid secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of disease prevention and control, and in particular relates to environmental physical method disinfection and purification equipment. Background technique [0002] Through cell compounding and hundreds of millions of years of evolution, single-celled life forms have gradually formed three major life systems of microorganisms, plants and animals, and established a biosphere that is interdependent, mutually restricted, and dynamically balanced. For hundreds of millions of years, the "war" between viruses and cells for control and survival has never stopped. Human beings rely on multiple protections and the cells of the immune system to defeat the virus will produce specific antibodies to prevent the virus from invading again and gain immunity. Since cells are the basic structural units of microorganisms, plants and animals, they are easy to become the adsorbers of viruses or the hosts of viruses, and there i...

Problems solved by technology

Chinese patent 201710384566.2 discloses a medical sterilizing air purifier without consumables and maintenance-free. Its core functional component is an air sterilizing purification cabin. Disinfection, but there are three major problems with this equipment. First, there are no self-cleaning measures for the layers and ventilation ducts in the purification cabin. The accumulated dust will become a hotbed for breeding and multiplying germs. A large number of germs spread; the second is to clean the dust in the cabin, using a complex high-pressure water pump system, which not only consumes a lot of water, but also may cause secondary pollution in the sewage containing germs after cleaning; third, the structure is complicated, and the cost and use cost are high. Only limited to medical use, not suitable for promotion at home and other places

[0006] Chinese patent 201420808084.7 discloses a new type of air sterilizer, which mainly uses ultraviolet rays and ozone to sterilize the air, but there are four major problems. The time is very long; the second is that the machine does not have a self-cleaning device, and the dust in the machine will become a place for the breeding and reproduction of germs, which is easy to cause the spread of germs; the third is that the machine has no control over the amount of ozone, and the long-term use of ozone exceeds the standard, which is harmful to people. and the environment can cause harm

Fourth, the function of the machine is single, and due to the different needs of people, the use occasions are greatly restricted

But there are two main problems. First, although it has a certain effect on air purification, the sterilizing effect of ultraviolet rays on air is extremely limited, and the required sterilization time is very long; second, the 5-layer filter used needs to be replaced regularly by professionals. Manual cleaning is not only expensive and complicated to operate, but all filter layers are prone to breeding and reproduction of germs

[0008] To sum up, the equipment currently on the market that uses physical methods to disinfect and purify the air generally uses multi-layer soft material filter layers. While filtering germs, they are also prone to become new places for germs to breed and reproduce, and there is a risk of germs spreading. At the same time, the existing patents and equipment lack the functions of non-consumption cleaning and self-cleaning, which makes it difficult to maintain long-term use effects. On the contrary, it is easy to cause secondary pollution and cross-infection of germs, which cannot meet the needs of use
