Long-life fresh air ventilator

Abstract

The invention discloses a long-life fresh air ventilator. The novel fresh air ventilator includes a return air bin, a fresh air bin, a filter adsorption bin, an air supply bin, an indoor return air inlet, an outdoor fresh air inlet, a coupling, a return air valve sheet, a fresh air valve sheet, a stainless steel wire mesh, a filtering self-cleaning device, a steel wire ball filter, a return air end differential pressure sensor, a fresh air mold end differential pressure sensor, a centrifugal fan and an indoor air outlet; the return air bin is located above the fresh air bin; the air supply binis arranged on the right of the return air bin and the fresh air bin, the stainless steel wire mesh, the filtering self-cleaning device, the steel wire ball filter, the return air end differential pressure sensor and the fresh air mold end differential pressure sensor are arranged between the return air bin, the fresh air bin and the air supply bins. The fresh air ventilator has the advantages that filtering and automatic cleaning are achieved, the service life of a filter element is prolonged, the purification ability is automatically recovered, the use cost is low and the ability is strong.

Description

technical field [0001] The invention relates to a long-life fresh air blower, in particular to a long-life fresh air blower with automatic filter cleaning, prolonging the service life of a filter element, automatic restoration of purification ability, low cost of use and strong ability. Background technique [0002] At present, there are many types of air filters on the market, and the use of filter media is also varied. Most products use three-stage filtration: steel mesh, activated carbon adsorption, and glass fiber membrane HEPA. The above three-stage filtration is not perfect in filtering air fibers, coarse particles, and dust, and there are many defects in the post-processing: 1. Poor filtration accuracy of fine dust; 2. Absorbing moisture in the air to breed mites and mold; 3. Replacement The post-recycling utilization rate is low, and the treatment and degradation are difficult, which brings new pollution. Indoor removable air filters can't solve the problem of pollu...

The above three-stage filtration is not perfect in filtering air fibers, coarse particles, and dust, and there are many defects in the post-processing: 1. Poor filtration accuracy of fine dust; 2. Absorbing moisture in the air to breed mites and mold; 3. Replacement The post-recycling utilization rate is low, the treatment and degradation are difficult, and new pollution is brought

Indoor removable air filters can't solve the problem of polluted air entering the room, and the air quality in other rooms cannot be guaranteed
