Title:
AIR FILTER WITH POSITIVE POWER GRID SUPPORT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2014/161124
Kind Code:
A1
Abstract:
An air filter with a positive power grid support structure comprises a housing (1) and a support frame (6). A piece of filter paper (2), a positive power grid (3), and a lower discharge grid (4) are sequentially disposed inside the housing (1) from top to bottom. The positive power grid (3) is coiled above the support frame (6). The support frame (6) is in the form of a perforated grid. An expansion and elongation phenomenon occurs on the positive power grid (3) after a long period of use, and excessive slumping of the positive power grid (3) is avoided because of the support effect of the support frame (6) on the positive power grid (3), thereby extending the service life of the positive power grid (3); in addition, because the positive power grid (3) is coiled above the support frame (6), the air filter is conveniently cleaned from the upper part when a certain amount of dust is gathered, thereby overcoming the defect in the prior art that the air filter cannot be cleaned or the cleaning work is excessively complicated.
