Background technique

The environmental conditions in which people live have a very significant impact on people's lives, especially air quality is closely related to people's life and health, but now due to environmental damage and climate change, air pollution is becoming more and more serious, and people spend most of their time It is indoors, especially the use of air conditioners makes the doors and windows closed and the air is not smooth enough, which is very harmful to people's health. Air quality is paid more and more attention by people. Some of the existing air purification devices can only remove dust or harmful gases alone, or are heavy, cannot be replaced and cleaned, and their purification efficiency is not high enough.

Utility model content

The technical problem to be solved by the utility model is to provide an air purification device that can remove harmful particles and harmful gases at the same time, can be replaced and cleaned, and is light in weight and low in purification efficiency. A box-type air purification device with long life and high air purification efficiency.

The technical solution adopted by the utility model to solve the technical problem is to provide a box-type air purification device, which includes a filter box, a plasma electrostatic net arranged in the filter box, and high-efficiency air particles arranged in the filter box filter screen (HEPA filter screen), activated carbon and photocatalyst filter screen, filter box cover, and a high-voltage discharge wire is arranged on the plasma electrostatic net.

In a box-type air purification device described in the present invention, the plasma electrostatic net is aluminum-based.

In the box-type air purification device described in the present invention, the high-efficiency air particulate filter is arranged on the side of the plasma electrostatic net without the high-voltage discharge wire.

In the box-type air purification device described in the utility model, the activated carbon and the photocatalyst filter are arranged on one side of the high-efficiency air particle filter.

A box-type air purification device implementing the utility model has the following beneficial effects: it uses multi-layer nets to remove dust and harmful gases in an orderly manner, and has high air purification efficiency, can be replaced and cleaned, has a long service life and is light in weight.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing and embodiment, in the accompanying drawing:

Fig. 1 is a perspective view of an embodiment of the utility model box-type air cleaning device;

Fig. 2 is an exploded view of an embodiment of the utility model box-type air cleaning device;

Fig. 3 is an exploded view of the plasma electrostatic net in the box-type air purification device of the present invention.

Detailed ways

As shown in Figures 1 to 3, Figure 1 is a perspective view of an embodiment of the utility model box-type air purification device, Figure 2 is an exploded view of an embodiment of the utility model box-type air purification device, Figure 3 is the utility model An exploded view of the Plasma Static Web 2.

Referring to Fig. 2 and Fig. 3, the utility model comprises filter net box 1, and filter net box 1 is hollow frame shape, and the inner wall of its top and bottom is provided with groove to stably arrange in it the plasma electrostatic net 2, filter The longitudinal surface of the net box 1 is provided with a layer of grids to stably install the plasma electrostatic net 2 and the filter net in the filter net box 1 . The plasma electrostatic net 2 is arranged on the side close to the grid in the filter box 1, and the plasma electrostatic net 2 includes a honeycomb aluminum base 23, a baffle 24 positioned around the aluminum base 23, and a plane side of the aluminum base 23. A plurality of side-by-side high-voltage discharge wires 21 parallel to the plane of the aluminum base 23 (only one is shown in the figure, and other high-voltage discharge wires 21 are omitted), and the high-voltage discharge wires 21 are fixed on the above-mentioned baffle plate by the discharge wire fixing member 22 within 24. The plasma electrostatic net 2 is aluminum-based, and it adopts the aluminum-based dust collection interface of the honeycomb porous surface. When the high-voltage discharge wire 21 is energized and discharged, it can absorb particles with relatively large diameters, such as dust and dust. Plasma electrostatic net 2 mainly removes particles with a diameter greater than 0.005mm, and it can be washed, and will not become dirty or reduce the adsorption efficiency due to the large number of adsorbed particles after a long time. Its reusable characteristics make consumers less The cost of consumables is reduced, and the aluminum-based plasma electrostatic net 2 is light in weight and easy to use.

A high-efficiency air particulate filter 3 (that is, a HEPA filter) is arranged on the side of the plasma electrostatic net 2 without the high-voltage discharge wire 21 , and the HEPA filter 3 is also located in the filter box 1 . HEPA is composed of very fine organic fibers and has a strong ability to capture particles. Its pore size is small and its adsorption capacity is large. It can remove smaller particles that were not removed by the plasma electrostatic net 2 in front of it. 0.0001mm, thus further purifying the air. It is also light in weight, reducing the weight of the entire device. One side of the HEPA filter screen 3 is provided with activated carbon and photocatalyst filter screen 4, which can remove SO ₂ , formaldehyde, benzene and other harmful substances in the air, and can also remove peculiar smell. Finally, the filter screen box 1 is sealed by the filter box cover 5 .

Due to the triple purification net of plasma electrostatic net 2, HEPA filter net 3, activated carbon and photocatalyst filter net 4, and its adsorption particles are removed in order of diameter from large to small, it can prevent larger particles from clogging in the HEPA filter net 3 Or activated carbon and photocatalyst filter screen 4 even reduced its purification efficiency, and extended the service life of HEPA filter screen 3, activated carbon and photocatalyst filter screen 4, and its purification efficiency is high. Experiments show that the suspended particles in the air are reduced by more than 99% after the device is used.

The utility model is assembled into a box type, which is convenient to be applied to an air purifier, and the aluminum-based 23 electrostatic net can be cleaned, prolonging its service life, making it have the advantages of light weight, long service life, and high purification efficiency.
