Air purifier and air purifying method
ActiveCN109028288AImprove purification efficiencyImprove use safety and reliabilityCombination devicesMechanical apparatusAir purifiersDust particles
The invention discloses an air purifier and an air purification method. The air purifier comprises an air inlet chamber and a mixing purification chamber which are arranged adjacently, wherein the airinlet chamber is provided with an air inlet chamber inlet and an air inlet chamber outlet; the air inlet chamber outlet communicates with the mixing purification chamber, and the mixing purificationchamber comprises an atomizer, a plurality of separation plates which are arranged opposite to the air inlet chamber outlet and a purified air outlet which is formed in the upper part of the side wallof the mixing purification chamber; and the atomizer is arranged between the air inlet chamber outlet and the separation plates and is positioned at the upstream positions of the separation plates. According to the air purifier and the air purification method, the atomizer is arranged in the mixing purification chamber, and the atomizer atomizes water and then mixes the water with the air flowingout of the air inlet chamber outlet, so that dust particles in the air are easier to be captured by the atomized water; and in addition, since the separation plates are arranged downstream of the atomizer along the flow direction of the airflow, the air mixed with water is separated and purified through the separation plates again to improve the purification efficiency of the air purifier.
