Abstract

The invention relates to the technical field of household appliances, in particular to an air purifier. The air purifier comprises a bracket and a main purifier body mounted on the bracket, the main purifier body comprises a fan and a filtering device, the fan is provided with an air inlet and an air outlet, and the filtering device is in a cylindrical shape and is arranged around the fan, whereinthe air inlet of the fan is formed corresponding to the end face of the filtering device, and the air outlet of the fan is formed corresponding to the side wall of the filtering device. To-be-purified air is introduced from the end face of the filtering device and discharged from the side wall of the filtering device so that the filtering device can achieve the effect of isolating the outside world from the fan noise in the working process of the air purifier, the noise at the air outlet of the fan can be reduced at the same time, correspondingly the electromagnetic noise of a motor in the fan and the noise of airflow at the air outlet of the fan can be further reduced without adding additional components, and the noise problem of the air purifier is further alleviated.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air purifier. Background technique [0002] At present, with the improvement of national living standards, the penetration rate of air purifiers is getting higher and higher. A traditional air purifier mainly includes a fan and a filter screen arranged on one side or circumferentially of the fan. The negative pressure generated by the rotation of the fan makes the air pass through the filter screen, and the air is purified by the filter screen and then sent out by the fan. [0003] In the current process of using air purifiers, the main criteria for judging the quality of air purifiers include three aspects: purification capacity, energy efficiency ratio and noise. Among them, the problem of noise is the most difficult to solve. The main noise sources of the above-mentioned air purifier are two aspects: first, the wind noise generated by the airflow driven by the...
