About the Air Purifier

As an Air Purifier Supplier, share with you. When ordinary people choose an air purifier, they usually only pay attention to the appearance and brand. A small number of people who are slightly knowledgeable will deliberately pay attention to the CADR value and filter. But in fact, for an air purifier, there are four really important parts, namely the fan, filter, air duct design and sensor.

Fan: The fan is used to provide continuous and stable power for the air purifier, so as to drive the fan system to inhale air, spray out clean air after purification, and gradually replace the indoor air to achieve the purification effect. In a sense, the fan It can be regarded as the core component of the air purifier. The fan with strong power and stable output is the guarantee of the excellent purification ability of an air purifier.

Many people know that the core data indicator of a purifier is the CADR value, which represents how many cubic meters of air an air purifier can purify in an hour. What more people don’t know is that the CADR value is closely related to the fan. In the case of the same filter element quality, the stronger the fan power, the higher the CADR value. This is because the higher the rotation speed, the higher the air intake and release speed.

Filter: The filter is also the point that many people pay attention to when buying an air purifier. In fact, the filter is also the easiest place to get ridiculous when the purifier is publicized. After all, just from the appearance, all the filters on the market are similar, and ordinary consumers can't tell whether a filter is good. I can't give you a test standard here, because many professional equipment is not something ordinary people can have, so today I will talk to you about some small knowledge about the filter.

Air duct design: The design of the air duct is related to a lot of data. The simplest is the CADR value. The straighter the air duct, the fewer the bends, the faster the air inlet and outlet, and the higher the purification efficiency. At the same time, the excellent air duct design can also reduce the noise when the machine is running, and bring a better mute effect.

Sensor: The sensor is roughly equivalent to the eyes and nose of an air purifier. It is the only external perception system of the purifier and is used to measure the pollutant index in the air. Here is also a simple science popularization for everyone, and talk about the working principle of the sensor.

At present, the sensors on the market are mainly divided into infrared and laser sensors. The working principles are similar. The light source (such as infrared light-emitting diode) inside the sensor emits a constant light source. When the air passes through the light, the particles in it will scatter the light and change the light. Strength, and the degree of attenuation is related to the concentration of particulate matter in the air.

On the other side of the light source, there is a high-sensitivity light detector (such as a phototransistor) to detect the light reflected by particles, and output a pulse width modulation signal according to the intensity of the reflected light to determine the concentration of particles in the unit of air . Particles of different sizes will also be distinguished, and different signals will be output to determine the current concentration of different pollutants in the air.
