Description

Composite Air Purifier

technical field

The utility model relates to an air purification device, in particular to a composite air purifier.

Background technique

Traditional air purifiers can be roughly divided into filter adsorption type, electrostatic dust collection type, photocatalyst type, negative ion type and ozone type according to their working principles. Among the above-mentioned types of air purifiers, the filter adsorption type has the disadvantage that the filter screen has a single structure and can only filter a small number of air impurities, and because the filter screen is too simple, the filtering effect on air impurities is not good, while other types of air purifiers , the functions are relatively single, have strong pertinence to air impurities, and will be affected by the environment, such as photocatalyst type, generally only for indoor formaldehyde, moss and other harmful gases, and will affect the indoor color wall, furniture surface paint In addition, when the photocatalyst material purifies the indoor air, it needs a certain amount of time and light. These all have restricted the development of air purifier.

Utility model content

The purpose of this utility model is to provide a composite air cleaner with simple structure, which can filter various air impurities and has good filtering effect.

The technical scheme of the utility model is realized in the following way: a composite air purifier includes a casing, a ventilator is arranged in the casing, and an air inlet is provided on the casing wall on the side of the air inlet end of the ventilator. The air outlet hole is provided on the casing wall on the side of the air outlet end of the fan, wherein an air filter is provided between the air inlet end of the fan and the air inlet hole, and the air filter is composed of The polypropylene filter layer, the HEPA high-efficiency filter layer, the cold catalyst layer and the activated carbon layer are formed by bonding each other, and a negative ion generator is also provided on the casing inside the air outlet.

In the above-mentioned composite air cleaner, the HEPA high-efficiency filter layer is composed of electret and electrostatic superfine polypropylene folds.

In the above composite air cleaner, the activated carbon layer is a honeycomb particle activated carbon layer, which is composed of modified activated carbon filled with paper honeycomb.

After adopting the above structure, the utility model can effectively remove indoor pollutants, such as bacteria, peculiar smell, virus, Soot, ammonia, pollen, formaldehyde, dust, hair, etc., and cooperate with the negative ion generator to generate a large number of negative ions, which combine with the germ cells in the air to transfer energy inside the cells and change the structure, leading to their death. Smoke, dust, pollen and other inhaled particles floating in the air gather and settle naturally to achieve the purpose of purifying the air.

Description of drawings

The utility model will be further described in detail below in conjunction with the embodiments in the accompanying drawings, but it does not constitute any limitation to the utility model.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a structural schematic diagram of the filter net of the present invention.

In the figure: casing 1, ventilator 2, air inlet hole 3, air outlet hole 4, air filter 5, polypropylene filter layer 5a, HEPA high-efficiency filter layer 5b, cold catalyst layer 5c, activated carbon layer 5d, negative ions generator6.

Detailed ways

Referring to Fig. 1, shown in Fig. 2, a kind of composite air purifier of the present utility model comprises casing 1, is provided with ventilator 2 in casing 1, the casing on the air inlet end side of ventilator 2 Air inlet 3 is provided on the wall 1, and air outlet 4 is provided on the wall of the casing 1 on the air outlet side of the fan 2, and an air filter is provided between the air inlet end of the fan 2 and the air inlet 3 Net 5, the air filter screen 5 is made of the polypropylene filter screen layer 5a, HEPA high-efficiency filter screen layer 5b, cold catalyst layer 5c and activated carbon layer 5d that are bonded to each other, and the polypropylene filter screen layer 5a can filter the hair in the air, 20 Dirt such as large particles of dust above microns can reduce the burden on the particle filter layer 3 behind it and prolong its service life. , The virus purification rate reaches 96%. The cold catalyst layer 5c can remove harmful gases in the air without light, and the activated carbon layer 5d can remove formaldehyde, moss and various peculiar smells in the air, and is effective against formaldehyde and hydrogen sulfide. The gas purification rate reaches 95%, which has the advantages of large adsorption capacity and fast adsorption speed. Among them, the HEPA high-efficiency filter layer 5b is composed of electret and electrostatic superfine polypropylene folded; the activated carbon layer 5d is a honeycomb granular activated carbon layer, which is composed of modified activated carbon with an iodine value>950mg/g filled with paper honeycomb.

During specific use, connect the power supply, start the air purifier, start the ventilator 2 and the negative ion generator 6, and the ventilator 2 sucks the indoor air from the air inlet 3 on the casing 1, so that the air containing pollutants passes through in sequence The polypropylene filter layer 5a, the HEPA high-efficiency filter layer 5b, the cold catalyst layer 5c and the activated carbon layer 5d filter different air pollutants through four filter layers, and the filtered fresh air passes through the ventilator 2 from the shell 1 The air outlet 4 is mixed with the negative ions generated by the negative ion generator 6 to circulate indoors to purify the air pollutants. Through the simultaneous purification of the two methods, the pollutants in the air can be quickly removed.
