Description

Granule type cigarette bullet

Technical Field

The utility model belongs to the technical field of heating cigarettes, and particularly relates to a particle type cigarette pellet.

Background

Along with the improvement of living standard, people pay more and more attention to their health problems, and in recent years, the attention on the health problems of smoking is high. In order to meet the changing consumption requirements of various large enterprises at home and abroad, various low-harm cigarette heaters without burning are developed in a break.

The cigarette that does not burn by heating produces the flue gas for the section of fuming that the cigarette propped up by heating, and its acceptance that produces the flue gas taste is better, and the heating that is marketed at present does not burn cigarette and props up mainly including section of fuming, cavity support section, cooling section and filter tip section, and the form of the interior tobacco of section of fuming has: orderly or disorderly filled reconstituted tobacco sheets, tobacco shreds, granular tobacco substances, blocky tobacco substances and the like. When the tobacco in the smoking segment is heated, the flavors and fragrances and the smoke agent loaded thereon are evaporated to generate smoke.

When the smoking material is a particle, the prior art generally fills up the smoking segment in a cigarette with a particle-type smoking material, and the central heating element is inserted into the smoking segment for heating, which can cause problems:

A. after the heating element is inserted, the fuming particles are heated only by the heat radiation of the heating element, and the heating is uneven due to the fact that the radial distances between the fuming particles and the heating element are different;

B. the outside air entering from the far lip end of the cigarette under the suction action of a user reduces the temperature of the fuming particles close to the far lip end of the cigarette, and influences the fuming effect of the fuming particles;

C. the cigarette has a hollow supporting section, a cooling section and a filter tip section, so that the whole cigarette is long, occupies a large space and is inconvenient to carry.

The present invention has been made to solve the above problems.

Thus, the heat spreader 15 has both the effect of blocking particulate smoking material and the heating of the airflow.

Furthermore, such a perforated bottom thermouniformer 15 is also very easy to load into empty paper tubes from the point of view of the manufacturing process of the pellet-type cartridges: the heat uniforming member 15 is directly inserted into the hollow paper tube from the distal lip end or the proximal lip end. Thus, the cartridge of the present invention is well suited for use in conventional particulate cigarette filling processes.

2. In the preferred technical scheme, a sealing piece 11 is additionally arranged at the far lip end of the smoke bomb so as to seal the heat-homogenizing piece 15 and the particle-type smoke substance.

3. The cartridges of the present invention may be used alone, with cooling and/or filtering being accomplished by a cooling section and/or a filtering section in the smoking article. The cigarette cartridge is in a product form and is smaller in structure.

4. When the heating cigarette cartridge is used, the heating modes comprise the following three modes:

method one, circumferential heating + end airflow heating:

the circumferential heating pipe can be used for heating the smoke cartridge, the heating pipe can directly heat the shell of the smoke cartridge, heat is conducted to the smoke generating substance 12 through the shell of the smoke cartridge, and air (including original air and subsequently entering air) in the uniform heating part 15 can be heated, so that the hot air can carry out airflow heating on the smoke generating substance 12;

method II, central heating and end airflow heating:

the central heating element is used to heat the cartridge, the heating element is inserted into the heat uniforming member 15 or extends into the smoking substance 12, the central heating element heats the air (including the original air and the subsequent air entering) in the heat uniforming member 15, so that the hot air heats the smoking substance 12 by airflow, and the central heating element can also directly conduct heat to the smoking substance 12;

method three, end airflow heating:
