A self-circulating air purification device

Abstract

The invention discloses a self-circulating air purification device, which includes a metal shell, and a melt-blown cloth installed in the metal shell, a transmission mechanism, an air purification mechanism, a circulation detoxification mechanism and a control unit; the melt-blown cloth passes through The transmission mechanism is movably installed in the metal shell; the transmission mechanism, the air purification mechanism and the circulation detoxification mechanism are respectively connected with the control unit; the metal casing includes a base and a shell fixed on the base; the transmission The mechanism includes a stepping motor, a worm connected with the stepping motor, a reduction worm gear matched with the worm, and a synchronous pulley set connected with the deceleration worm gear; the synchronous pulley is mainly driven by a synchronous belt shaft and four driven shafts; the self-circulating air purification device of the present invention, the air is purified through multiple channels, the purification effect is good, and the melt-blown cloth used for primary purification can be cyclically detoxified and electrostatic electret, realizing self-circulation Circulating air purification effect.

Description

technical field [0001] The invention relates to an air purification device, in particular to a self-circulating air purification device, which belongs to the technical field of air purification equipment. Background technique [0002] In the prior art, the air purification device, the hospital ward and the negative pressure ambulance use the air pressure difference to make the medical staff on the upwind side of the airflow, and the patients or the epidemic area are on the downwind side, which has a certain impact on the staff (medical staff). It has a protective effect, but it does not disinfect the virus in the air; at the same time, the polluted air in the intensive care unit, negative pressure vehicles and other spaces is discharged to the outside to pollute the atmospheric environment. In addition, the filter screens of the air inlets of these devices absorb a lot of pollutants and are difficult to deal with, so the filter screens can only be replaced continuously, which...

Problems solved by technology

[0002] In the prior art, the air purification device, the hospital ward and the negative pressure ambulance use the air pressure difference to make the medical staff on the upwind side of the airflow, and the patients or the epidemic area are on the downwind side, which has a certain impact on the staff (medical staff). It has a protective effect, but it does not disinfect the virus in the air; at the same time, the polluted air in the intensive care unit, negative pressure vehicles and other spaces is discharged to the outside to pollute the atmospheric environment

In addition, the filter screens of the air inlets of these devices absorb a lot of pollutants and are difficult to deal with, so the filter screens can only be replaced continuously, which increases the cost and workload, and also pollutes the environment
