An air purification device for fresh air and air purification system

Abstract

The invention discloses an air cleaning device for a fresh air and air cleaning system. The fresh air and air cleaning system at least comprises an indoor side air channel shell with a draught fan assembly and a cavity channel, wherein the length of the indoor side air channel shell is the same as that of a window-cave lower sill. The air cleaning device comprises a cleaning main machine box installed below the air channel shell. A cleaning module and an inner-outer circulating switching mechanism are sequentially installed in the box up and down, and a sealing inserting part is arranged between the cleaning module and the inner-outer circulating switching mechanism to be used for spacing. A decoration face plate with an indoor air inlet is arranged on the indoor side face of the box, and outer air inlets are formed in the back face of the box. The indoor air inlet and the outer air inlets are located in the two corresponding side faces of the lower portion of the box respectively and are communicated with the inner-outer circulating switching mechanism of the box respectively, wherein the inner-outer circulating switching mechanism has the function of sealing the indoor air inlet and the outer air inlets in a one-way mode; the inner-outer circulating switching mechanism is communicated with the cleaning module at the upper portion through an upward air channel opening, and cleaning channels formed in the cleaning module are upwards guided out of the box to be communicated with the cavity channel of the air channel shell at the upper portion.

Description

technical field [0001] The invention relates to an air purification device for a fresh air and air purification system that is matched with building doors and windows for exchanging and purifying indoor and outdoor air, and belongs to the technical field of building ventilation. Background technique [0002] With the rapid development of the economy and the acceleration of urbanization, the number of cars per capita is increasing, and more and more exhaust gas is discharged into the air, causing air pollution.
