Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a novel dust filter, includes frame 1 and with frame 1 articulated inside casing 2, install filter element in the inside casing 2, filter element is including filtering fibrous layer that the particle size set gradually by big-end-up, set up at fibrous layer top surface and the nylon net layer 301 of bottom surface, set up and be connected the constitution in the fibrous layer outside and nylon net layer 301 and be used for holding borduring canvas layer 302 of the cavity of fibrous layer.

In practical application, wind enters the filtering element of the inner frame 2 from the outer frame 1, enters the locomotive from the inner frame 2 through the filtering of the nylon mesh layer 301 and the fiber layer, the nylon mesh layer 301 firstly filters sundries with larger volume, and then the fiber layer can effectively filter sand and dust in the wind due to the characteristics of large air permeability and high filtering effect.
