Information

The air purifier is mainly composed of air purifier motor, fan, air filter and other systems. Its working principle is: air purifier motor and fan make indoor air circulate.

After the polluted air passes through the air filter screen in the machine, various pollutants are removed or adsorbed. Some types of air purifiers also install negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage when working), which continuously ionizes the air and produces a large number of negative ions, which are sent out by the micro fan to form negative ion air flow, so as to achieve the goal of cleaning The purpose of air purification.

1. Purification principle of passive adsorption filtration (filter purification)

The main principle of passive air purifier is: air is pumped into the machine by the impeller driven by air purifier motor, and the air is filtered through the built-in filter screen, which can mainly filter dust, odor, toxic gas and kill some bacteria. And the filter is mainly divided into: particulate filter and organic filter. The particulate filter screen is divided into coarse filter screen, fine filter screen and fine filter screen.

The main function of the air purifier motor is to generate mechanical work by electric drive, which is transmitted to the impeller blade through the main shaft. The pressure difference between the inner and outer sides of the blade is generated, which drives the air into the air purifier.

2. Active purification principle (no filter screen type)

The fundamental difference between the principle of active air purifier and passive air purifier is that the active air purifier gets rid of the limitation of fan and filter screen.

Instead of passively waiting for the indoor air to be pumped into the purifier for filtration and purification, it effectively and actively releases purification and sterilization factors into the air. Through the characteristics of air diffusion, it reaches every corner of the room to purify the air without dead angle.

Here, the main function of the air purifier motor is basically the same as that of the passive adsorption filter air purifier, except that the active air purifier motor will continue to exhaust the air mixed with sterilization factors to the indoor space after it inhales the external air through the impeller blades.

3. Dual purification (active purification + passive purification)

This kind of purifier is actually a combination of passive purification technology and active purification technology.
