Description
Technical Field
The invention relates to the technical field of household appliances, in particular to an air purifier.
Background
With the increase of health consciousness, people pay more and more attention to air quality, so that the demand for air purifiers is increasing.
The working principle of the air purifier is that the air is driven to flow through the rotation of the wind wheel in the equipment, and the flowing air is filtered by the filter screen and then enters the environment, so that the aim of air purification is fulfilled. The most important performance index of the air purifier is a CADR value (clean air output ratio value), and the greater the CADR value, the higher the purification efficiency of the air purifier. The main factor affecting the performance index is the air intake, which is the air intake passing through the inside of the product per hour, and when the fan speed is consistent with each basic parameter, the larger the air intake area is, the larger the air intake is. However, due to the limitation of the fan and the first air channel structure, the conventional air circulation is that air enters the first air channel through the filter screen and then through the circular air inlet in the middle of the air channel shell, and the fan drives the wind wheel to rotate to output filtered air. The structure of the first air duct is designed according to the Archimedes spiral principle, so that the area of an air inlet arranged in the middle of the air duct shell cannot be changed at will. Therefore, in order to realize larger air intake, the air intake area needs to be increased or the air speed loss needs to be reduced.
