AI Technical Summary
Traditional high-efficiency filters are prone to deformation under high pressure, have high airflow resistance, insufficient mechanical strength, and are difficult to effectively clean dust accumulation on the filter element.
It adopts a fixed frame and support structure, including transverse support comb teeth and longitudinal support pressure plate. The vibration module drives the transverse support to vibrate slightly, maintaining the shape of the filter element and cleaning the accumulated dust.
It increases the filtration area and efficiency, reduces airflow resistance, enhances mechanical strength, extends filter life, and reduces pressure drop caused by dust accumulation.

Abstract
Claims
1. A low resistance, high efficiency filter characterized by, include: A shaping frame (1) is provided with a filter element (2) inside the shaping frame (1). The back of the shaping frame (1) is provided with several transverse supports (3) and a longitudinal support (4) through a mounting bracket (14). The longitudinal support (4) is located behind the transverse supports (3). The transverse supports (3) and the longitudinal support (4) are used to support the leeward side of the filter element (2). The transverse support (3) includes a support bar (31) and several support comb teeth (32), which are inserted into the folds of the filter element (2) to maintain the shape of the filter element (2); The longitudinal support (4) includes a pressure plate (41), and a vibration module (44) is provided in the middle of the front side of the pressure plate (41). The vibration module (44) abuts against one of the transverse supports (3) and can drive the transverse support (3) to vibrate slightly when working.
