Problems solved by technology

Most of the existing air purifiers are composite types, that is, a variety of purification technologies and material media are used at the same time. These air purifiers undoubtedly have good purification effects, but their prices are also relatively expensive. The purification effect of the lower purifier is not outstanding
Moreover, the filter parts need to be replaced frequently, otherwise the effective purification effect cannot be achieved, and even the possibility of re-pollution may occur.

Abstract

The invention discloses a high-efficiency air purifier. The high-efficiency air purifier comprises a chassis, a filtering layer, a purifying device, an internal electrode, a cover and an exhaust fan, wherein the chassis, the filtering layer, the purifying device and the cover are sequentially matched from bottom to top, the internal electrode is arranged in the purifying device, the filtering layer is arranged at the upper part of the chassis, the lower surface of the filtering layer faces the inside of the chassis, the upper surface of the filtering layer faces the purifying device, and the filtering layer comprises 3-5 porous ceramic filtering layers which are stacked. The high-efficiency air purifier has a simple structure and can be used conveniently, solid impurities in purified air are removed preliminarily, haze, dust and other impurities in air can be further adsorbed by electrified water in a static electric field, and the purpose of purifying the purified air in a high efficiency manner can be achieved.

Description

technical field [0001] The invention relates to an ambient air impurity removal and purification device, in particular to a high-efficiency air purifier. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), household appliances that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building. [0003] There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure photomineralization technology, HEPA high-efficiency filtration technology, electrostatic du...
