Yet the storage ash amount of this filter core is less, and intake resistance is bigger simultaneously, and filter effect is not very desirable.

Therefore, how existing filter core is made improvement, thereby it is less to make it can solve filter core storage ash amount effectively, the problem that intake resistance is bigger is the problem that those skilled in the art need solution badly.

The utility model content

In view of this, the main purpose of the utility model is to provide a kind of filter core, and it is less that the structural design of this filter core can effectively solve in the prior art filter core storage ash amount, the problem that intake resistance is bigger.

For realizing above-mentioned purpose, the utility model provides a kind of filter core, comprises filter material and the filter core framework that is arranged on the said filter material outside, and said filter material forms by nonwoven is folding, and its cross section is snakelike; The height pleat of said filter material is spaced apart.

Preferably, in the above-mentioned filter core, said filter core framework adopts injection moulding and said nonwoven to be integral the formula structure.

Preferably, in the above-mentioned filter core, each side of said nonwoven is fixedly connected with said filter core frame seal.

Preferably, in the above-mentioned filter core, each side of said nonwoven and said filter core framework are sealedly and fixedly connected through PUR.

Preferably, in the above-mentioned filter core, the height pleat of said nonwoven bottom evenly distributes at interval.

Preferably, in the above-mentioned filter core, the both sides of arbitrary low pleat of said nonwoven are high pleat.

With respect to prior art, the novel technique effect of this use is:

Experiment showed, the filter core that the utility model provides, its filter material is the alternate nonwoven of height pleat; Compare and the high nonwoven filter material uniformly of pleat of the prior art, it is little to have overcome its storage ash amount effectively, the shortcoming that intake resistance is big; When improving filter core storage ash amount, reduced intake resistance.
