Air purifier
First Claim
1. An air purifier comprising:
- a housing having two air intake passages at two opposite lateral sides thereof through which outside air passes to the inside of said housing, an air output port at a bottom side thereof, an air intake chamber communicating between said air intake passages and said air output port;
an induced-draft fan mounted in the air intake chamber of said housing and adapted to induce air from said air intake passages through said air intake chamber toward said air output port;
a plurality of air filters respectively mounted inside said housing and adapted to filter air passing from said air intake passages to said air intake chamber, each of said air filters comprising two electrically insulative frames fastened together, a first electrically conductive air filter element and at least one second electrically conductive air filter element spaced within said electrically insulative frames; and
a high-voltage static electricity generator mounted inside said housing and connected to the first electrically conductive air filter element of each of said air filters;
wherein said high-voltage static electricity generator is controlled to provide high-voltage static electricity to said first electrically conductive air filter element, causing said at least one second electrically conductive air filter element to produce positive static electricity at one side and negative static electricity at an opposite side for catching dust from air passing through.

Abstract
An air purifier including a housing which has two air intake passages at two lateral sides and an induced-draft fan in an air accumulation chamber between the air intake passages, a plurality of air filters respectively mounted between the air accumulation chamber and the air intake passages, each air filter including two electrically insulative frames fastened together, and a plurality of metal wire gauze filters, and a high-voltage static electricity generator mounted inside the housing and connected to one metal wire gauze filter, the high-voltage static electricity generator providing high-voltage positive static electricity to one metal wire gauze filters, causing the other metal wire gauze filters to produce positive static electricity at one side and negative static electricity at an opposite side for catching dust from air passing through.
