Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of other embodiments without departing from the spirit and scope thereof as defined by the appended claims.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," and the like are for illustrative purposes only and do not denote a single embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, the long-life multilayer filter is provided with a shell 1, wherein a first filter cotton 3, a second filter cotton 4 and a third filter cotton 5 are sequentially arranged in the shell 1; at least one air inlet 2 is arranged on the shell 1 outside the first filter cotton 3, and an air outlet 6 is arranged on the shell 1 outside the third filter cotton 5.

The filtering efficiency of the first filter cotton 3 on particles with the particle size of more than or equal to 1mm is more than 99.97%, the filtering efficiency of the second filter cotton 4 on particles with the particle size of more than or equal to 0.3mm is more than 99.97%, and the filtering efficiency of the third filter cotton 5 on particles with the particle size of more than or equal to 0.05mm is more than 99.97%. The reason for adding the three-layer filter cotton is to filter out large-particle dust, oil stain or fiber by the first filter cotton 3 and the second filter cotton 4, and prevent the large-particle foreign matters from blocking the filtering capacity of the third filter cotton 5 filter.
