Description

Multifunctional air purifying device

Technical Field

The utility model relates to an air purification equipment, concretely relates to multi-functional air purification device belongs to air purification technical field.

Background

Air purifier derives from the fire control usage, 1823, john and charles dien utility model a novel smog protector, can make the fire fighter avoid smog invasion and attack when putting out a fire. In the 80's of the 20 th century, the emphasis on air purification has turned to air purification approaches, such as home air purifiers. The past filters are very good in removing foul smell, toxic chemicals and toxic gases in the air, but cannot remove mould spores, viruses or bacteria, and the new air purifiers for families and offices can not only clean the toxic gases in the air, but also purify the air and remove the bacteria, viruses, dust, pollen, mould spores and the like in the air.

At present, the air purifier has various different design and manufacturing modes, and each technological change brings remarkable effects for improving the indoor air quality of people. And this is only one: it is desirable to purify indoor air to improve the quality of life of people. With the rapid development of industrial modernization and the rapid promotion of urbanization construction, urban air pollution is more and more serious, and the physical health of people is greatly influenced. However, the air purification devices adopted by people at present, such as the air purification layer of an indoor unit of an air conditioner, are only a layer of filter screen or filter plastic foam, can only filter large-particle dust in the air, cannot degrade harmful gases in the air, and cannot sterilize, disinfect and remove peculiar smell, so that in a long-time closed air-conditioned room, the air is dry, smelly, bacteria are bred, the air is turbid, the pollution is serious, and the air-conditioned room is not beneficial to the health of people. Meanwhile, various air purification devices are available in the market, which have functions of disinfection, sterilization, deodorization, dust removal and harmful gas degradation, and the like, and the purification devices have various purification functions only by integrating various purification devices with single purification functions, and cannot exert respective optimal purification functions due to the influence of air with different pollution degrees and even part of the purification devices do not exert the due value of the purification devices, for example, one purification device with the functions of dust removal and harmful gas degradation is used in an air environment only polluted by dust, wherein the device for degrading harmful gas does not play a due role, but consumes the service life, energy consumption and the like. For example, when the content of dust is relatively high or relatively low relative to the content of harmful gas, the same purification mode is adopted, so that the purification effect is greatly reduced. Also, the multi-energy purification equipment in the prior art can not make corresponding adjustment according to the air in different environments to purify the air in a targeted manner, but rather, the multi-energy purification equipment carries out rigid program type purification, so that the purification effect of part of the purification equipment is poor or even idle, the damage speed of the equipment is accelerated, and the energy is consumed in vain.
