Filter tip

Abstract

The present application provides a filter tip including a filter element material and a surface layer. The filter element material includes a non-woven wire mesh layer and a paper-pulp layer. The non-woven wire mesh layer includes a plurality of first fibers and a plurality of mesh holes, wherein the first fibers are combined with each other, and each mesh hole is located between the first fibers. The paper pulp layer includes a plurality of plant fibers, a portion of the plant fibers are located on one side of the non-woven wire mesh layer, and a portion of the plant fibers pass through the mesh holes and entangle with the first fibers. The surface layer is wrapped around the periphery of the filter element material.

What is claimed is: 
     
         1 . A filter tip, comprising:
 a filter element material comprising:
 a non-woven wire mesh layer comprising a plurality of first fibers and a plurality of mesh holes, wherein the first fibers are combined with each other, and each mesh hole is located between the first fibers; and 
 a paper pulp layer comprising a plurality of plant fibers, wherein a portion of the plant fibers are located on one side of the non-woven wire mesh layer, and a portion of the plant fibers pass through the mesh holes and entangle with the first fibers; and 
   a surface layer wrapped around the periphery of the filter element material.   
     
     
         2 . The filter tip according to  claim 1 , wherein the first fibers comprise a plurality of polypropylene fibers. 
     
     
         3 . The filter tip according to  claim 2 , wherein the percentage by weight of the polypropylene fibers in the filter element material is less than 45%. 
     
     
         4 . The filter tip according to  claim 2 , further comprising a plurality of softened particles uniformly distributed on the surface of the filter element material. 
     
     
         5 . The filter tip according to  claim 4 , wherein the percentage by weight of the softened particles in the filter element material is 1.0% to 15.0%. 
     
     
         6 . The filter tip according to  claim 1 , wherein the first fibers comprise a plurality of wood fibers. 
     
     
         7 . The filter tip according to  claim 1 , further comprising a functional carrier provided inside the filter tip. 
     
     
         8 . The filter tip according to  claim 1 , further comprising a scented crystal ball provided inside the filter tip. 
     
     
         9 . The filter tip according to  claim 1  having a hardness of greater than or equal to 70%. 
     
     
         10 . The filter tip according to  claim 1  having an inhalation resistance of 120 mmWG to 800 mmWG, and the filter tip has a length of 60 mm to 160 mm and a diameter of 16 mm to 25 mm. 
     
     
         11 . The filter tip according to  claim 1 , wherein the filter element material has a liquid absorptive capacity of ≥230%.
