Detailed Description
The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that the embodiments described in the present specification are not exhaustive, and do not represent the only embodiments of the present invention. The following examples are given for the purpose of clearly illustrating the invention of the present invention and are not intended to limit the embodiments thereof. It is obvious to those skilled in the art that various changes and modifications can be made on the basis of the embodiments described above, and it is within the scope of the present invention to provide the invention with various changes and modifications which are obvious and belong to the technical idea and the utility model.
As shown in fig. 2, the hollow filter stick 20 for heating cigarette according to the present invention is an integrally formed structure. The outer part 23 of the hollow filter stick 20 is in a smooth cylindrical shape, a through hollow cavity is formed inside the hollow filter stick 20, in the axial direction of the hollow filter stick, the diameters of the areas 24 at the two ends of the hollow cavity are smaller than the diameter of the middle area 25 of the hollow cavity, the diameters of the areas 24 at the two ends of the hollow cavity and the diameter of the middle area 25 of the hollow cavity are in smooth transition, and the diameter of the middle area 25 of the hollow cavity is gradually increased from the two ends to the center. That is to say, the hollow area at the two ends of the hollow cavity is small, the hollow area in the middle is large, and the shape of the middle area is olive-shaped.
The integrally formed hollow filter stick of the utility model is preferably prepared in the following way. The material is heated and plasticized by spraying steam onto a cellulose diacetate tow sprayed with glyceryl triacetate, and the shaped outer surface of a circular sleeve with a certain inner diameter and a middle core rod reciprocate to form a hollow filter stick with a smooth outer surface, small hollow areas at two ends, a large hollow area in the middle and an olive-shaped hollow area in the middle. In a preferred forming mode, the hollow filter stick is a cellulose diacetate tow filter stick. The single denier of the cellulose diacetate tow of the hollow filter stick is 5.0-22.0 denier, and the content of the glyceryl triacetate is 14.5-34.5%.
Preferably, the outer diameter of the hollow filter stick 20 is 5.8mm to 7.5mm. The length of the hollow filter stick 20 is 20 mm-80 mm. The hollow area of the two end regions 24 of the hollow cavity is 3.14mm 2 ～19.63mm 2 . The maximum hollow area of the middle area 25 of the hollow cavity is 8.55mm 2 ～30.19mm 2 . Here, the hollow area refers to a cross-sectional area of the hollow cavity orthogonal to the axial direction.
