Abstract

The invention discloses an indoor and outdoor air filtration exchange device and relates to the air purification technology, in particular to an indoor and outdoor air filtration exchange device, and aims to solve the problem that indoor and outdoor air exchange cannot be realized by using the conventional air purifier. The indoor and outdoor air filtration exchange device comprises a surface shield, a time control switch, a power switch connecting rod, a power switch, a filtering layer, a rotary valve, an axial fan, an inner sleeve pipe and an outer sleeve pipe, wherein the outer sleeve pipe is perpendicularly inserted in a wall body, and sleeves the inner sleeve pipe; the axial fan and the filtering layer are sequentially arranged in the inner sleeve pipe from front to back; the rotary valve sleeves the front end of the outer sleeve pipe; the surface shield sleeves the front end surface of the outer sleeve pipe; a surface shield air outlet is formed in the middle on the end surface of the surface shield; a plurality of surface shield air inlets are uniformly distributed in the outer lateral wall of the surface shield radially; a plurality of sleeve pipe air outlets are uniformly distributed in the upper part at the rear end of the outer pipe part of the outer sleeve pipe along the periphery surface. The indoor and outdoor air filtration exchange device is used for improving indoor air quality.

Description

technical field [0001] The invention relates to an air purification technology, in particular to an indoor and outdoor air filtering and exchanging device. Background technique [0002] With the improvement of living standards, people have gradually increased their requirements for the indoor environment and air quality of living and working. Now the urban air pollution and smog are increasing year by year. No matter in winter or summer, they are unwilling to open windows to replace the indoor air. PM2. 5 pollution particles will enter the room with the windows open. With the improvement of living standards, air conditioners are also very popular. When the air conditioner is turned on, the windows need to be closed. In the winter in the Northeast, it is also necessary to close the windows to maintain the indoor temperature. Time closure will reduce the oxygen content of the air in the room and reduce the air quality, which will have adverse effects on the body. An independe...
