Abstract

The invention discloses a metal-free-material filter element. The filter element is made from a metal-free material, a supporting frame is omitted inside the filter element, the two ends of a foldablefiltering assembly are subjected to hot melting fixing through a bottom plate and a top plate, the filtering efficiency of the foldable filtering assembly can be furthest developed, and under the effects of the bottom plate and the top plate, the stability of the foldable filtering assembly can also be guaranteed; the metal-free-material filter element is not deformed in the using process, and the manufacturing cost is saved. The invention also provides a filter with the metal-free-material filter element, the structure of the filter is of a detachable structure so that the filter element canbe changed, and the metal-free-material filter element has the advantage of being recyclable.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a metal-free filter element and a filter thereof. Background technique [0002] A filter refers to an accessory that filters impurities or gases through filter paper. Generally refers to the car filter, which is an accessory of the engine. According to different filtering functions, it is divided into: oil filter, fuel filter, and fuel filter further includes gasoline filter, diesel filter, oil-water separator, hydraulic filter, etc. [0003] The inventor previously disclosed a sealed filter structure, including a support ring, the support ring is provided with a filter element assembly, the lower end of the support ring is provided with a lower end cover, and the upper end of the support ring is provided with an upper end Cover, the filter element assembly is located between the upper end cover and the lower end cover, the upper end cover is connected with a sealing disc, and ...
