[0015] Compared with the prior art, the beneficial effects of the present utility model are:
[0016] An air purifier capable of detecting PM2.5 and dust of the present utility model has at least one of the following beneficial effects during use:
[0017] The air purification efficiency is greatly improved by adopting the two-way air inlet and one-way air outlet method. At the same time, the PM2.5 and dust particles in the air are detected by the air detection system. After combining the detection data, the controller targets the operation of the first air inlet system or the second air inlet system in the air, effectively performs purification operations according to the air quality, improves the purification efficiency, and has stronger reliability. The air detection system has a PM2.5 detection sensor and a dust detection sensor. When the detected PM2.5 content in the air is greater than the preset value, the first air inlet system of the air operates. The first air inlet system adopts double-sided air inlet. The air inlet cover is in a disc structure, and a dense first air inlet is opened on the surface of the air inlet cover. A dust-proof net and a disinfection mechanism are provided on the inner side wall of the air inlet cover. The disinfection mechanism sterilizes and filters the PM2.5 in the air. When the dust content in the air is detected by the dust detection sensor to be greater than the preset value, the controller controls the operation of the second air inlet system.

The difference is that the first air inlet system is arranged on the front and rear sides of the fuselage, while the second air inlet system is arranged on the upper left and upper right of the fuselage. The second air inlet system consists of an air inlet seat and a spraying system. After the air inlet seat sucks the air into the chamber in the fuselage through the second air inlet and the air inlet groove, it is filtered by the air filtration structure. This filtration method is the same as that of the first air inlet system. Since the air inlet seat needs to pass through the spraying system when sucking air, the spraying system includes a sprayer and a water-hanging filter net. The pump group sprays the liquid in the first water tank from the sprayer onto the water-hanging filter net. The aperture of the water-hanging filter net is much smaller than the diameter of the dust. After the dust in the air passes through the water-hanging filter net, the dust stays on the water-hanging filter net, and finally the dust flows into the second water tank after gravity and liquid flushing, thereby filtering the dust in the air.
