Description

TECHNICAL FIELD

[0001] The present application relates to the field of air purification equipment, in particular to an air purifier. BACKGROUND

[0002] An air purifier is a device that can adsorb and filter harmful substances in the air, which is widely used in homes, offices, hospitals and other places to improve indoor air quality and protect people's health.

[0003] In practical applications, air purifiers face the problem of balancing smooth air outlet and firm wind wheel connection. First, in order to ensure smooth air outlet, air purifiers need to design reasonable air duct structure and efficient air flow system. However, in the actual manufacturing process, due to unreasonable air duct design, excessive air resistance and other problems, the air purifier has poor air outlet, which affects the purification effect. Secondly, the firmness of the wind wheel connection is also a key factor of the performance of the air purifier. The wind wheel is an important component inside the air purifier, which is responsible for driving air flow to achieve air purification. The firmness of the wind wheel connection is directly related to the running stability and service life of the air purifier. If the wind wheel connection is not firm, it may loosen, fall off and make noise, which will cause the air purifier to malfunction, and even cause safety hazards.

[0004] However, in the pursuit of smooth air outlet, the firmness of the wind wheel connection is often affected. For example, in order to reduce air resistance, the number and volume of the wind wheel and the shell connection may be reduced, which affects the stability of the wind wheel connection. On the contrary, if the firmness of the wind wheel connection is too emphasized, the air resistance may be increased, which affects the smooth air outlet.

[0005] Therefore, how to ensure the firmness of the wind wheel connection while ensuring the smooth air outlet has become a big problem in the design and manufacturing process of the air purifier.

[0006] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.
