Filter mesh frame, filter mesh structure, and usage thereof

Abstract

A filter mesh frame (800), a filter mesh structure (900), and usage thereof are provided. The filter mesh frame (800) includes a first mesh (100) and a second mesh (200). The first mesh (100) surrounds to form a cylinder with respect to a first pivot direction (710). The second mesh (200) surrounds the first mesh (100) with respect to the first pivot direction (710) and includes a plurality of bar structures (210), where the bar structures (210) protrude outward with respect to the first mesh (100) and are disposed parallel to the first pivot direction (710). A groove (201) parallel to the first pivot direction (710) is formed on one side of each bar structure (210) with respect to the first mesh (100). The filter mesh structure (900) includes the filter mesh frame (800) and a filter material (500) disposed between the first mesh (100) and the second mesh (200).
