Self-circulation air purification device

Abstract

The invention discloses a self-circulation air purification device. The device comprises a metal shell, and melt-blown cloth, a transmission mechanism, an air purification mechanism, a circulating disinfection mechanism and a control unit which are mounted in the metal shell, wherein the melt-blown cloth is movably installed in the metal shell through the transmission mechanism; the transmission mechanism, the air purification mechanism and the circulating disinfection mechanism are in communication connection with the control unit; the metal shell comprises a base and an outer shell which is fixedly erected above the base; the transmission mechanism comprises a stepping motor, a worm in transmission connection with the stepping motor, a speed reduction turbine set matched with the worm and a synchronous pulley set in transmission connection with the speed reduction turbine set; and the synchronous pulley set is formed by a synchronous belt main drive shaft and four driven shafts. According to the self-circulation air purification device, air is purified for multiple times, the purification effect is good, circulating disinfection and electrostatic electret can be conducted on the melt-blown cloth for primary purification, and the self-circulation air purification effect is achieved.

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...

[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
