Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.

Referring to fig. 1 to 8, the bag-type filter material provided by the present embodiment includes an outer frame 1 and a plurality of filter bodies 2, the filter bodies 2 are installed at one side of the outer frame 1, a plurality of ventilation openings 3 are uniformly formed on another side surface of the outer frame 1, the ventilation openings 3 are arranged in one-to-one correspondence with the filter bodies 2, a filter cavity 4 is formed inside the filter body 2, and the filter cavity 4 is communicated with the ventilation openings 3.

The filter body 2 is composed of a protective layer 5, an efficiency layer 6 is arranged inside the protective layer 5, and the protective layer 5 can be fixedly bonded with the efficiency layer 6.

Wherein, the filter body 2 comprises a protective layer 5 and an efficiency layer 6, the efficiency layer 6 is encapsulated in the protective layer 5, and the efficiency layer 6 has a curved section structure, in particular a folded paper structure.
