Novel efficient filter

Abstract

The invention relates to a novel efficient filter. The novel efficient filter comprises a shell which is of a cylindrical structure and a cover covering an upper opening of the shell, wherein the cover and the bottom of the shell are both of a porous structure. The novel efficient filter further comprises filter paper arranged in an inner cavity formed by the shell and the cover, wherein each piece of filter paper is provided with a plurality of bent parts in the same width, the bent parts are distributed in the length direction of each piece of filter paper, the multiple pieces of filter paper are stacked together with the bent parts matched, the filter paper can be sealed in the shell in a compressed mode by the cover, and the distance between every two adjacent bent parts becomes smaller during compression. The filter paper can be sealed conveniently and easily by means of the cover and shell structure to form the main structure of the filter. Due to the fact that the bottom of the shell and the cover are both of the porous structure, the filter paper can be sealed, and it can be guaranteed that air can flow from one end of the efficient filter to the other end of the efficient filter. The shell and the cover are fixed through a plurality of buckle structures, it is guaranteed that the filter paper can be compressed by the cover by different degrees, and the larger the compression amount is, the better the filtering effect is.

Description

technical field [0001] The invention relates to a filter, in particular to a novel high-efficiency filter. Background technique [0002] Most of the existing high-efficiency filters use filter paper as the adsorption material, but the filter paper material has the defects of being not oil resistant and easy to absorb water, resulting in shortened service life of the filter and low adsorption efficiency. The ventilation efficiency of the existing simultaneous filter cannot be adjusted, and cannot flexibly adapt to various environments. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a novel high-efficiency filter with a simple structure. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a novel high-efficiency filter, comprising: a shell of cylindrical structure and a cover covering the opening on the shell, the cover and the shell The bottoms are all porous ...
