Embodiment 1

[0050] As shown in FIG. 1, a heat-not-burn cigarette includes a filter section 1, a cooling section 2 and a smoke generation section 3 connected in sequence. The filter section is composed of a special cellulose acetate filter stick which has cooling function and entraps low smoke, the cooling section is formed by wrapping a cooling stick with wrap paper 4, and the cooling stick 201 is mainly formed by paper 5 coated with a phase change cooling material. The forming process of the cooling stick is shown in FIG. 10: the paper coated with the cooling material is first cut to be in a target size, the cut paper 5 is pre-pressed with lines, and then the pressed paper is fed into a ZL-23 forming machine to form the cooling stick. A mold 6 is used for the forming. The mold 6 includes a bell mouth 601 and a cavity 602 matching the cooling stick 201 in shape, the bell mouth 601 is butted with the cavity 602, and the paper enters the mold from a large open end of the bell mouth 601. The bell mouth can be provided with recessed and raised grooves therein, so that the paper is roughly in a wave shape when passing through the bell mouth, and the paper then can conveniently enter the cavity 602 for repeated bending and forming to obtain the cooling stick.
