As an example, the outer periphery of the bottom of the centrifugal fan blade 53 has a first arc surface 533, the inner wall of the diffuser 42 has a second arc surface 421, the first arc surface 533 matches the contour of the second arc surface 421, and the second arc surface 533 There is a gap D between the first arc surface 533 and the second arc surface 421 .

In some embodiments of the present application, the gap D is in the range of 3-4 mm.

It is easy to understand that the centrifugal fan blade 53 will vibrate slightly during the rotation process, and the range of the gap D is limited to 3-4mm, which can not only allow the slight vibration of the centrifugal fan blade 53, but also effectively prevent the airflow from passing through the gap D. The air flow enters the centrifugal fan assembly 50 from the fan air inlet 531, thereby improving the purification efficiency of the fan and reducing the purification noise.

Preferably, D=3.5mm, which can not only improve the purification efficiency of the fan, reduce noise, but also allow the centrifugal fan blade 53 to rotate normally.

Optionally, the upper cover plate of the centrifugal fan blade 53 is a deflector 534, the center of the deflector 534 has an air outlet, the outer edge of the deflector 534 is obliquely upward, and the diameter of the deflector 534 and the centrifugal fan blade 53 The angle between them is β=8-12°.

Further, the upper inner wall of the diffuser 42 in the flow guide cover 40 is provided with a first flow guide surface 422 , and the lower side of the flow guide plate 534 is provided with a second flow guide surface 5341 . The first air guide surface 422 is roughly parallel to the second air guide surface 5341 , and the two air guide surfaces jointly guide the air outlet direction of the centrifugal fan assembly 50 so that the wind is obliquely upward.

It is easy to understand that the angle between the outlet wind direction of the centrifugal fan assembly 50 and the x direction (that is, the radial direction of the centrifugal fan blade 53 ) is approximately β, and the outlet air flow can be decomposed into the first split flow along the x direction and the first split flow along the x direction. The second shunt in the y direction.

The first split flow flows out from the first side wall air outlet 112 and the second side wall air outlet 122 , and the second split flow flows out from the top air outlet 161 . Through this arrangement, the impact of the outflow of the centrifugal fan assembly 50 on the inner wall of the casing 10 can be alleviated, the air volume is large, and the noise is low.

Preferably, β=10°, so that the air output from the centrifugal fan assembly 50 can be evenly sent out from the first side wall air outlet 112 , the second side wall air outlet 122 and the top air outlet 161 , with uniform air output and low noise.

In the air cleaner 100 of the embodiment of the present application, under the suction of the centrifugal fan assembly 50, the external air enters the air duct 20 inside the casing 10 through the five air inlets, and passes through the purification assembly 30, the air guide in turn from bottom to top. The flow cover 40 and the centrifugal fan assembly 50 are purified and rectified by three layers during the process of passing through the purification assembly 30, and then enter the centrifugal fan assembly 50 evenly and efficiently under the action of the flow guide 40, and the clean air is discharged from the fan outlet 532 The air flow is sent to the external environment through three air outlets. During the whole purification process, the air purifier 100 not only has high purification efficiency and uniform air output, but also has low energy consumption and low noise.

Embodiment three

As people pay more and more attention to air quality in their lives, it has become the first choice for people to improve indoor air quality through air purifiers. In the air purifier industry, an air purifier based on electrostatic dust collection technology works as follows:

Air purifiers based on electrostatic dust collection technology all include generators and collectors placed between the air inlet and outlet. The generators and collectors are placed opposite each other at a fixed distance. The generator forms a plasma field under the action of high-voltage ionization. The air molecules are ionized and positively charged. The ionized air is accelerated to collide with other particles under the action of the electric field force formed by the generating pole and the collecting pole, and make it positively charged. Through a series of snowball-like avalanche effects, the dust and bacteria passing through the electric field are charged. And move to the collector, and finally be absorbed by the collector; the collector module itself contains the collecting plate and the repelling plate, and has the opposite charge. The repulsion effect pushes the dust to move towards the collector plate.

With the accumulation of technical experience, air purifiers with increasingly mature electrostatic dust collection technology have quickly been widely accepted by the market due to their technical advantages such as washable and reusable, electrostatic field to kill bacteria, and ability to capture and purify smaller particles.
