Description

microwave disinfection air purifier

technical field

The utility model relates to a purification device, in particular to a microwave disinfection air purifier.

Background technique

At present, in terms of air disinfection, ultraviolet light, ozone and bactericidal enzyme air sterilizers are commonly used air disinfection equipment. Ultraviolet air sterilizer uses filtration and ultraviolet radiation to filter out bacteria-carrying dust in the air and sterilizes viruses, but the ultraviolet penetrating ability is weak and can only kill viruses on the surface of the filter bed; ozone sterilizer uses ozone to sterilize the air, but the remaining Ozone is harmful to the human body; the bactericidal enzyme air disinfector has certain pertinence to bacteria and viruses. At present, during the air disinfection process of the above-mentioned equipment, bacteria and viruses in the air pass through the disinfection area in the equipment instantly, and the disinfection and sterilization time is short, so the effect is difficult to guarantee. In addition, air disinfection and sterilization can also be achieved by using disinfectants such as chlorine-containing preparations and peracetic acid, but at present, this type of method is mainly realized by manual spraying, and is rarely used in small air purification and disinfection equipment. At present, indoor air disinfection and sterilization in living environment has become a problem that the country and people generally pay attention to. Therefore, it is necessary to develop an indoor air disinfection purifier that can be used in living environment.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the above-mentioned technologies, and provide a microwave disinfection air purifier with simple structure and reasonable design, which combines air filtration purification and microwave disinfection.

In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is: an inner shell is set inside the outer shell, and its front end is connected by a filter chamber composed of a microwave shielding net, a centrifugal fan is fixed in the inner shell, and the filter chamber A microwave generator is installed on the top, symmetrical spray heads on both sides are connected with the circulating water pump, and symmetrical infrared disinfection lamps are installed in front of the centrifugal fan.

The utility model has the advantages of:

1. The structure is simple and the design is reasonable. This device uses the basic principles that viruses and bacteria are usually attached to the dust surface and that viruses and bacteria are easy to denature, lose vitality, and kill under the action of microwaves, and organically combine air filtration and purification with microwave disinfection. The rotation of the fan drives the indoor air to circulate through the utility model, which not only realizes the purification of the air, but also realizes the disinfection and sterilization of the air. In the process of microwave disinfection, it can also realize the function of spraying water to humidify the air.

2. The utility model is mainly composed of a shell with an air inlet and an air outlet, a centrifugal fan, a filter chamber for microwave disinfection, a microwave generator, and a water humidification pipe. The structure is simple and easy to manufacture.

3. The microwave disinfection box adopted by the utility model is equipped with a microwave protection screen to prevent microwave leakage, so as to ensure that the human body will not be harmed during the microwave disinfection process, and the indoor air can also be sterilized under the condition of indoor activities. Sterilize.

4. The microwave disinfection process of the utility model is an intermittent disinfection process, and the fan stops running during the disinfection process. Therefore, it has little effect on the rise of the indoor air temperature, and the disinfection energy consumption does not exceed 0.1kWh.

5. The utility model can be used in indoor places such as family rooms, hospital wards, offices, conference rooms, restaurants, lounges, station waiting rooms, airport waiting rooms, etc., to realize indoor air disinfection and purification in the above places, and has broad market prospects .

Detailed ways

Embodiments of the utility model are described in further detail below in conjunction with the accompanying drawings.

As can be seen from Figures 1-3, the utility model is that the outer shell 1 is fitted with an inner shell 2, and its front end is connected by a filter chamber 4 composed of a microwave shielding net 7, and a centrifugal fan is fixed in the inner shell 2 6. A microwave generator 8 is installed on the top of the filter chamber 4, and symmetrical spray heads 9 are connected to the circulating water pump 5 on both sides, and a symmetrical infrared disinfection lamp 3 is installed in front of the centrifugal fan 6.

An air inlet 10 and an air outlet 11 are respectively provided on the front and rear sides of the outer casing 1 .

An activated carbon filter 12 is arranged at the air outlet 11 in the outer casing 1 .

The filter chamber 4 is equipped with a high temperature resistant filter cotton 13 .

In the utility model, when the microwave generator is closed and the fan is started, the airflow flows through the air inlet, the left microwave protective screen, the heat-resistant packing layer, the right microwave protective screen, and the fan, and is sent out from the air supply port, and the airflow flows through the heat-resistant packing. When filling the packing layer, impurities such as large particles of dust in the air are filtered on the surface of the packing layer.

Turn off the fan, start the micro-submersible pump, and humidify the heat-resistant packing layer.

Start the microwave generator to sterilize the heat-resistant packing layer by microwave.

The connection relationship of the main components of the utility model is that the left side is an air inlet, the middle is a filter cavity and a microwave generator, and the right side is a centrifugal fan and an air outlet. The air flow enters from the air inlet, enters the centrifugal fan through the filter chamber, is pressurized by the centrifugal fan, and is discharged through the air outlet.

The mechanism of microwave sterilization is that bacteria and adults, like any biological cells, are a condensed medium composed of complex compounds such as water, proteins, nucleic acids, carbohydrates, fats and inorganic substances, among which water is the main component of biological cells , the content is 75-85%, because the various physiological activities of bacteria must be carried out with the participation of water, and the growth and reproduction of bacteria, the absorption of various nutrients is completed through the diffusion, penetration and adsorption of the cell membrane of. Under the action of a certain intensity of wavelength, the insects and bacteria in the material will also relax due to molecular polarization, and at the same time absorb microwave energy to heat up. Because they are condensed substances, the force between molecules intensifies the energy state conversion of microwave energy to heat energy, so that the proteins in the body are simultaneously affected by non-polar heat energy movement and polarity rotation, and their spatial structure is changed or destroyed. to denature the protein. After the protein is denatured, its solubility, viscosity, expansion, permeability, and stability will change significantly, and the biological activity will be lost. On the other hand, the non-thermal effect of microwave energy plays a role in sterilization that is not available in conventional physical sterilization. special role. It is also one of the causes of bacterial death.
