Description

technical field [0001] The invention relates to the field of air purification, in particular to a small air cleaner. Background technique [0002] With the improvement of people's requirements for air quality, air purifiers are gradually promoted and used in people's lives. The commonly used air treatment devices for air purifiers are catalysts and electrostatic precipitators. The catalysts used for air purification need certain Only a certain air pressure difference can make the air quickly penetrate the catalyst layer. In the design of the purifier, the realization of the air pressure difference requires wind power equipment with sufficient power. Such wind power equipment usually has certain size and installation requirements.

Problems solved by technology

[0003] In terms of electrostatic precipitators, due to high-voltage static electricity, it is necessary to design a certain air insulation distance; due to the limitation of the use of air purifiers, high-voltage electrostatic electrodes must be installed in the air circuit, so the air insulation distance cannot be reduced during design. After use, the electrostatic electrodes are easily deformed and the insulation distance becomes smaller, and it is easy to cause insulation failure in a small-sized insulating structure to cause arcing or electric shock, which brings difficulties to the design of small-sized air purifiers; so that commercially available Small-sized air purifiers are often unable to integrate electrostatic precipitators, which affects the air purification effect
