Electric field cleaning device and method for filter membrane of air purifier

Abstract

The invention discloses an electric field cleaning device and method of a filtering membrane of an air purifier. A dust collection electrode lifting device is arranged at the front side of the filtering membrane of the air purifier, a discharge electrode lifting device is arranged at the rear side of the filtering membrane of the air purifier, a horizontal dust collection electrode is connected between two transmission belts on the dust collection electrode lifting device, a horizontal discharge electrode is connected between two transmission belts on the discharge electrode lifting device; motors are connected with an MCU control system, the MCU control system controls the two motors to simultaneously positively rotate so that the dust collection electrode and the discharge electrode move from bottom up until reaching a top position; meanwhile, the MCU control system controls a power supply switch circuit to switch on a 220V alternating-current power supply, a strong electric field is formed between the discharge electrode and the dust collection electrode, and electrons move towards the dust collection electrode to ensure that dust particles attached on the surface of the front side of the filtering membrane of the air purifier are attracted on the dust collection electrode by negative charges, thus the filtering membrane of the air purifier is cleaned, and thus the air purifying efficiency is improved, secondary pollution is reduced, and the service life of the filtering membrane is prolonged.

Description

technical field [0001] The invention relates to the field of air purification, and relates to an air purifier using a filter membrane, in particular to a device for cleaning the filter membrane so as to improve the air purification efficiency. Background technique [0002] Air purifiers, also known as air cleaners, can absorb, decompose or transform various air pollutants including PM2.5, dust, etc., and can effectively improve air cleanliness. In a relatively closed space, due to the persistent and uncertain characteristics of the release of air pollutants, the use of air purifiers to purify indoor air is one of the recognized methods to improve indoor air quality. At present, ordinary air purifiers mainly use layer-by-layer filtration technology to achieve air purification. The core is to install a filter membrane inside that can filter out dust and fine particles in the air. As the air passes through the filter membrane, dust and other pollutants are captured by the filt...

Problems solved by technology

However, after long-term operation of the air purifier, a large amount of dust will accumulate on the filter membrane, which will block the filter holes and increase the wind resistance, which will affect the effect of air purification and easily cause secondary pollution. Therefore, after using the filter membrane for a period of time , or manually removed for cleaning, or directly replaced, the cost of consumption is relatively high
