Liftable air purifier air door

Abstract

The invention relates to the field of air purifiers and discloses a liftable air purifier air door. The liftable air purifier air door comprises a small air door body, a big air door body, a face plate and a transmission device. The small air door body covers a ventilation opening in the middle of the big air door. The big air door body covers a ventilation opening in the middle of the face plate. The transmission device comprises a motor, a driving block and a push rod. One end of the push rod is connected with the small air door body and the big air door body, and the other end of the push rod is connected with the driving block. The motor drives the push rod to move up and down through the driving block, so that the small air door body and the big air door body are opened and closed. The liftable air purifier air door has the beneficial effects that by adopting the liftable air door, wind is evenly blown out from the periphery of the air door, noise can be reduced, and diffusion of clean air is facilitated; the opening degree of the air door can be adjusted by controlling the lifting degree of the small air door body and the big air door body, so that flexibility is higher, and the liftable air purifier air door is rich in scientific and technological sense; and when a purifier is stopped, the air door is automatically closed, dust can be prevented from entering the machine, and secondary pollution can be avoided.

Description

technical field [0001] The invention relates to the field of air purifiers, in particular to a liftable damper of the air purifier. Background technique [0002] Air purifiers are used in household, medical, industrial and other fields, and are mainly used to absorb, decompose or transform various pollutants in the air to improve the cleanliness of the air. In the air purifier, the air inlet is generally located at the bottom or side, and the air outlet, that is, the damper is located on the upper part or the side of the purifier. As the air supply device, the damper is an important structural component. At present, most air purifier dampers use integral The plastic part structure, the air door is exposed, cannot be opened and closed, and cannot be lifted, and this structure, because the air is directly blown out, the noise is relatively large, and because the air outlet is exposed, it is easy to collect dust and cause secondary pollution of the air. Therefore it is necessa...
