Dynamic flow distributing apparatus of air purifier

Abstract

The invention discloses a dynamic flow distributing apparatus of an air purifier, wherein a flow distributing mouth is mounted inside an outdoor air inlet; a flow distributing piece is mounted inside the flow distributing mouth; the flow distributing piece is connected to a rotary shaft; one end of the rotary shaft is connected to a motor; the motor is connected to a control module; the control module is connected to an oxygen sensor; a throat pipe is set on the back of the flow distributing mouth; a flow mixing cavity is set on the back of the throat pipe; and a blower is set on the back of the flow mixing cavity. By adopting the dynamic flow distributing apparatus provided herein, the mixing proportion of outdoor air and indoor air is controlled by dynamically controlling the intake volume of the outdoor air, thus effectively reducing the humidity and dust of air that is sucked indoor, prolonging the service period of an air filter core, decreasing the possibility of forming ozone and stabilizing the ozone content.

Description

technical field [0001] The present invention relates to an air purifier, in particular to a dynamic distribution device of the air purifier. Background technique [0002] At present, most of the air intake systems of air purifiers at home and abroad are indoor circulation, and a few manufacturers use fixed inhalation of outdoor air and indoor air to mix and circulate. They have the following serious defects: for the indoor circulation of the air intake system, the oxygen content drops sharply due to the repeated circulation of the indoor air; while for the fixed inhalation of outdoor air, while continuously inhaling outdoor air, the humidity and dust in the outdoor air are continuously inhaled, flowing through The active air filter plate often causes the formation of ozone after short-circuit discharge, and often causes blockage when flowing through the passive air filter, which greatly reduces the filtration efficiency and service life of the passive air filter.

Problems solved by technology

They have the following serious defects: for the indoor circulation of the air intake system, the oxygen content drops sharply due to the repeated circulation of the indoor air; and for the fixed inhalation of outdoor air, while continuously inhaling the outdoor air, it continuously inhales the humidity and dust in the outdoor air, and flows through it. Active air filter plates often cause ozone to be formed after short-circuit discharge, and often cause blockage when passing through passive air filter elements, which greatly reduces the filtration efficiency and service life of passive air filter elements
