Abstract

The invention discloses a double-sided filter structure, which is used for ventilation and dustproofing of electronic instruments. It includes a filter bracket and at least two pieces of filter mesh. The filter bracket is a separate supporting part, including an integrated The frame and the middle support bar, both sides of the filter screen bracket include buckle parts integrally formed on the filter screen bracket for buckling the filter screen, and the filter screens are respectively removed from the filter screen. The mesh bracket is installed on both sides of the filter bracket, and is fixed to both sides of the filter mesh bracket in a buckle manner through the buckle part, and the middle support strip separates the filter mesh located on both sides. The device of the present invention has a simple structure, few parts, and is easy to fix and disassemble the filter.

Description

technical field [0001] The invention relates to a double-sided filter net structure for ventilation and dust prevention of electronic instruments. Background technique [0002] Some electronic instruments are provided with air vents, and in order to prevent dust and other sundries from passing through the air vents, a filter screen structure is usually arranged in the air vents. [0003] Because the material of the filter screen is very soft and easily deformed, it needs to be fixed with supporting parts to form a filter screen assembly before it can be used. [0004] Based on the requirements for air purification rate, it is sometimes necessary to use a double-sided filter structure. A kind of double-sided filter net structure of prior art is as Figure 17 and 18 as shown, Figure 17 For its exploded perspective, Figure 18 For perspective assembly drawing. The double-sided filter mesh structure is a “3+2” structure, that is, two layers of filter mesh 110A and 110B are ...
