Problems solved by technology

However, since the paint or plastic on this metal shell is sprayed, its anti-corrosion and anti-static performance is not good, and it is easy to fall off and oxidize, so that moisture or dust particles in the air will easily adhere to the metal shell. On the casing, the casing is corroded and oxides are produced, which shortens the service life of the high-efficiency filter and cannot meet the environmental requirements. The static electricity and oxide dust particles generated by it seriously affect the working environment, resulting in serious In addition, oxide d

Example Embodiment

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0022] figure 1 Is a front view of an embodiment of the present invention; figure 2 for figure 1 An enlarged view of Part A; image 3 Is a top view of an embodiment of the present invention; Figure 4 It is a bottom view of an embodiment of the present invention.

[0023] Such as Figure 1 to Figure 4 As shown, the high-efficiency filter includes a housing 2, a filter element 1 and a steel frame 4. The top of the housing is provided with an air inlet 8. The steel frame 4 and the outer wall of the filter element 1 form a U-shaped space that is fixedly connected. The material of the housing 2 It is plastic with a shape of ∩, which can be injection molded at one time by a mold, and the lower end of the housing 2 is inserted into the U-shaped space formed by the steel frame 4 and the outer wall of the filter element 1.

Abstract

The invention discloses a high-efficiency filter which comprises a shell, a steel frame and a filter element, wherein, the top of the shell is provided with an air inlet, and a fixedly connected U-shaped space is formed between the steel frame and the outer wall of the filter element. The high-efficiency filter is characterized in that the shell is made of plastic and has a reverse U shape; and the lower end of the shell is inserted into the U-shaped space formed between the steel frame and the outer wall of the filter element. As the shell of the high-efficiency filter adopts the plastic as the raw material and can be formed by injection molding in one step, the shell has very high sealing waterproof property, anticorrosive property and antistatic performance, thus effectively solving the problems of easy shedding of the paint or plastic coating on the surface of metal shell and air deterioration caused by dust particle generation as well as effectively reducing the cost and playing a positive role in saving energy and protecting environment.

Description

technical field [0001] The invention relates to a high-efficiency filter, in particular to a high-efficiency filter that can be molded at one time and has a waterproof function, and belongs to the technical field of electronic mechanical products. Background technique [0002] High-efficiency filters are used to filter dust particles in the air, thereby improving and improving the air quality of the working environment. Therefore, in the fields of semiconductors, precision electronics, medicine, medical treatment, food, military machinery, metallurgy, light industry, printing and dyeing, coating, etc., High-efficiency filters are necessary equipment to create a dust-free and sterile working environment. [0003] At present, high-efficiency filters generally use metal shells, and then spray paint or plastic on the outer surface of the metal shells, so that high-efficiency filters can achieve anti-corrosion and anti-static effects. However, since the paint or plastic on this ...
