Cyclone air purifier

Abstract

The invention discloses a cyclone air purifier, capable of effectively separating dust even without the second cyclone body. The cyclone air purifier provided according to the invention includes a cylinder-shaped body with an inflow port provided in the lower and an air channel for rotationally flowing the air inflowing from the inflow port; a plurality of cyclone bodies provided outside of the body for filtering dust in the air intaking from the air channel; a circulation tube provided inside of the body for guiding air discharging from each cyclone body to the air channel; an ionization device with a high voltage electrode part forming outside surface of the circulation tube and a ground electrode part forming inside surface of the body, for guiding the dust to inflow to the each cyclone body by using centrifugal force and electric gravitational force at the same time. And, a plurality of through holes for discharging compression air are formed in the side of the circulation tube to make dust in the air circulating along the air channel cleave to inside surface of the body.

Description

technical field [0001] The invention relates to an air purifier, in particular to an air purifier using a cyclone. Background technique [0002] A cyclone is a device used to capture and filter solid or liquid particles floating in the air. It works by using the principle of centrifugal force and gravity to separate particles in the rotating air. Such cyclones are commonly used in vacuum cleaners, etc., and Korean Laid-Open Patent Publication No. 2005-0026218 discloses the above-mentioned cyclone and a vacuum cleaner having the cyclone. [0003] However, the cyclone as described above uses the first cyclone body and the second cyclone body to separate dust in order to improve the dust collection efficiency, but since all the air discharged from the first cyclone body flows into the second cyclone body, the second cyclone body The pressure loss and noise generated in the body are very large. [0004] And, because the above-mentioned cyclone is provi...

Problems solved by technology

[0003] However, the cyclone as described above uses the first cyclone body and the second cyclone body to separate dust in order to improve the dust collection efficiency, but since all the air discharged from the first cyclone body flows into the second cyclone body, the second cyclone body The pressure loss and noise in the body are very large

[0004] And, because the above-mentioned cyclone is provided with the inlet that flows into the first cyclone body on the side of the main body, the amount of air that can flow into the main body is limited, so it is difficult to apply to the air purification that needs to purify more air at the same time. device
