Title:
AIR FILTER WITH FILTER NET SEAL RING
Document Type and Number:
WIPO Patent Application WO/2014/161127
Kind Code:
A1
Abstract:
An air filter with a filter net seal ring comprises a filter outer frame (2), a net base (1), and a piece of filter paper (4). The edge of the filter outer frame (2) is connected to the edge of the net base (1). The filter paper (4) is disposed inside the filter outer frame (2). A seal ring (3) is disposed on the inner wall of the filter outer frame (2). The upper surface of the seal ring (3) is attached to the filter paper (4). The air pressure of a fan in the filter is baffled by the seal ring when the air filter is used, so that the filter outer frame and a connecting part of the net base are sealed, thereby effectively preventing leakage of to-be-filtered air from the connecting part, and ensuring the air filtering efficiency.
