All the above applications The contents are incorporated herein by reference.

technical field

Background technique

Heat-not-burn cigarettes generate smoke by heating flavor-loaded tobacco sheets, and the production principle is similar to traditional cigarettes, so the taste of smoke is well accepted. At present, the mainstream smoking device on the market that provides the heat energy required for heating the non-burning smoke in the heating part is the central heating design. The central heating type heating cigarette requires the heating piece (or needle) to be inserted into the cigarette core end of the cigarette. When the smoking material moves backward, a support section is usually provided for support. When the smoke passes through this support section, it will be enriched, which will cause the temperature of the flue gas to rise briefly, resulting in the difference between the flue gas and the traditional cigarette smoke. The final sensory evaluation of the feeling of suction also has a greater impact.

In addition, in heated cigarettes, the draw resistance and weight of cigarettes are also important indicators that affect their quality. Usually, a filter rod forming machine is needed in the production process of the filter rod. The weight of the filter rod directly affects the effect of the upper machine compounding, and the heavy filter rod is not conducive to the compounding effect of the forming machine. At the same time, the fluctuation of the suction resistance of the filter rod section has a great influence on the suction resistance of the whole cigarette, thereby affecting the sensory quality.

The number may be plural, and the term "one" should not be understood as a limitation on the number.

Referring to FIGS. 1 to 6 , a heating cigarette aerosol generating system according to an embodiment of the present application will be described in detail below. Specifically, the heating cigarette aerosol generating system includes a smoking section 10 , a filtering section 20 , a multi-channel cooling section 30 and a cooling section 40 . The filter section 20 and the multi-channel cooling section 30 form a filter rod.

One end of the smoking section 10 and one end of the multi-channel cooling section 30 are respectively disposed at both ends of the filtering section 20 . The cooling section 40 is installed at the other end of the multi-channel cooling section 30 . In this way, the smoking section 10 , the filtering section 20 , the multi-channel cooling section 30 and the cooling section 40 can form the heated cigarette aerosol generating system.

The filter section 20 is provided with at least one flue gas channel 201 , wherein the flue gas channel 201 respectively forms at least one outlet at both ends of the filter section 20 . After the smoking section 10 is heated to form an aerosol, the aerosol passes through the flue gas channel 201 from the outlet of the filter section 20 connected to one end of the smoking section 10 through the flue gas channel 201 . Flow to the outlet of the filter section 20 connected to the other end of the multi-channel cooling section 30 .

In an optional embodiment, the multi-channel cooling section 30 is provided with at least one communication channel 301 . Each of the communication channels 301 respectively forms at least one communication port at both ends of the multi-channel cooling section 30 . The communication port of the multi-channel cooling section 30 connected to the filter section 20 is communicated with the flue gas channel 201 . The communication port of the multi-channel cooling section 30 connected to the cooling section 40 is disposed toward the cooling section 40 .

The cooling section 40 is made of acetate fiber or polylactic acid.

Preferably, the volume ratio of the space occupied by the communication channels 301 on the multi-channel cooling section 30 to the volume of the entire multi-channel cooling section 30 is between 50% and 70%. If it is higher than this range, it means that the communication channels 301 of the multi-channel cooling section 30 are too many, so that when the multi-channel cooling section 30 is fabricated, it is difficult to form the multi-channel cooling section 30 or the formed Uneven shape. If it is lower than this range, the overall cooling effect of the multi-channel cooling section 30 will decrease.

In addition, the cross section of the communication channel 301 is a regular polygon, wherein the central axis of the communication channel 301 of the regular polygon coincides with the central axis of the multi-channel cooling section 30 . Through such a design, the multi-channel cooling section 30 can be made by extruding some plant sludge, especially during extrusion, since the cross-section of the communication channel 301 is a regular polygon, the multi-channel The channel cooling section 30 can be uniformly stressed during extrusion, thereby ensuring the cooling effect of the multi-channel cooling section 30 and reducing the overall weight of the multi-channel cooling section 30 at the same time.

In the latter figure, the line formed by the points on the two radii on the fan-like shape is positioned as a straight line dividing line, and the arc line opposite to the straight line dividing line is the arc dividing line.

In addition, the dividing line on the cross-section of each of the communication channels 301 is directly opposite to one side of the cross-section of the communication channel 301 . Preferably, the distance between the dividing line on the cross section of each communication channel 301 and the edge on the cross section of the communication channel 301 is between 0.5 mm and 1.0 mm.

It can be understood that, since the dividing line on the cross-section of each communication channel 301 is directly opposite to an edge on the cross-section of the communication channel 301, the multi-channel is formed by extrusion. During the cooling section 30 , each part of the multi-channel cooling section 30 can be uniformly and symmetrically stressed, thereby making the multi-channel cooling section 30 more compact, thereby improving the cooling effect of the multi-channel cooling section 30 .

This can ensure the stability of the overall structure of the multi-channel cooling section 30 . In addition, when the multi-channel cooling section 30 is produced by extrusion molding, the multi-channel cooling section 30 can be effectively prevented from being deformed because the wall thickness between the channels is too thin.

The communication channel 301 of the regular polygon may be a regular triangle, a regular quadrilateral, or the like.

Preferably, the communication channel 301 of a regular polygon may be a regular hexagon. Accordingly, the sector-like communication channels 301 are implemented as six.

In addition, the communication channels 301 on the multi-channel cooling section 30 are symmetrically arranged. Therefore, when the smoking section 10 is heated to generate aerosol, the aerosol can pass through the smoking channel 201 at a uniform speed. Diffusion, and thus, when the user inhales, no suction resistance will be formed due to the uneven distribution of the aerosol.

It can be understood that, the multi-channel cooling section 30 may be implemented by extruding plant components from plant powder as raw materials. Preferably, the outside of the filter section 20 is wrapped with a film. The smoking section 10 includes tobacco leaves and expanded cut stems produced by the method of randomly oriented papermaking combined with thick pulp reconstituted tobacco leaves and expanded cut stems or dry reconstituted tobacco leaves.

The cooling section 40 has a three-dimensional network structure, and its longitudinal porosity is between 50% and 90%.

Preferably, the filter section 20 is a three-dimensional network structure or a polymer rod-shaped structure with through holes formed by foaming through foaming technology. Preferably, cooling section 40 and filtering section 20 are acetate tow.

Preferably, the outer wall of the multi-channel cooling section 30 is provided with a plurality of cooling grooves 302 extending along the length direction of the multi-channel cooling section 30 .
