Description

Air purifier

The present invention relates to an air purifier, and more particularly to an air purifier having an electrostatic dust collecting effect.

Suspended particles floating in the air or allergens such as bacteria and dust mites are often the main factors affecting the quality of air. Therefore, air purifiers are often used indoors to improve air quality to ensure that clean air can be inhaled by the human body. It does not cause discomfort to the human body.

Referring to FIG. 1, there is disclosed an air cleaner 9 comprising a hood 91, a fan 92, a screen 93 and a closing plate 94, and the fan 92 and the filter The net 93 is sequentially placed in the hood 91, and the hood 91 is closed by the closing plate 94. An air outlet 911 is defined in the peripheral wall of the hood 91; an air inlet 921 is connected to the side of the exhaust fan 92, and a HEPA filter is disposed in the air inlet 921; the filter 93 is disposed on the exhaust fan 92.

In summary, the main feature of the present air purifier is that by applying a high voltage, the dust collecting body 22 and the charging body 23 form two electric fields of opposite polarities, and the principle of attracting opposite charges can be passed. The dust particles of the dust collecting assembly 2 are positively charged under the discharge of the pole lines 231 of the charging body 23, and under the action of the Coulomb force, the positively charged dust particles can be negatively charged. The dust collecting body 22 moves and adheres to the surface of each of the layer plates 221 of the dust collecting body 22 to ensure that the fine dust particles are no longer dispersed with the air flow, thereby achieving the effect of purifying the air.

In addition, the dust particles attached to the dust collecting body 22 are easily removed by the worker without causing the accumulation of particles to block the air inlet 131, and even more costly to save the conventional timing replacement filter to maintain The dust collecting assembly 2 has long-lasting use and relatively improves the ease of use of the air cleaner. Therefore, the present air purifying machine can maintain a better air intake to achieve the effect of ensuring the operation efficiency of the air cleaner.
