Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a double-layer mesh filter which is easy to clean. Background Art

[0002] The development of industry and transportation has caused increasingly serious air pollution. For example, PM2.5 has attracted much attention in recent years. Air pollution is harmful to human health. People need to breathe air to maintain life. An adult breathes about 20,000 times a day and inhales 15 to 20 cubic meters of air. Therefore, polluted air has a direct impact on human health. Air pollution includes gaseous pollution such as sulfur oxides, carbon monoxide, nitrogen oxides, hydrocarbons, chlorine, hydrogen monoxide, fluorides, chlorinated hydrocarbons, etc. Particle pollution includes suspended particulate matter, coal smoke, black smoke, acid mist, dust, etc. Odor pollution includes chlorine, hydrogen sulfide, potassium sulfide, thiols, methylamines, etc. The more common air pollutants include suspended particulate matter, carbon monoxide, sulfur oxides, nitrogen oxides and hydrocarbons.

[0003] According to the mesh filter in the prior art, a single-layer metal mesh or a multi-layer filter mesh is basically used. The filtering efficiency of the single-layer filter mesh is low, and the filter holes are easily clogged. After long-term use, when the multi-layer filter mesh is clogged internally, since the multi-layer filter mesh usually has a complex structure, it needs to be decomposed layer by layer when cleaning, which increases the difficulty and time consumption of cleaning, resulting in the inability to clean quickly and effectively. In addition, the gaps between the multi-layer filter mesh are small, and dirt and particles are easily accumulated. Clogging is more common, and more frequent cleaning and maintenance are required.

[0004] Therefore, in view of the above problems, a double-layer mesh filter which is easy to clean is proposed. Utility Model Content
