| (54) | NOVEL ELECTRONIC CIGARETTE CARTRIDGE |
| (57) The present invention provides a novel electronic cigarette cartridge. In use, the
heat in the heating zone (1-2) is retained, and the granules will not fall out of
the heating zone. The smoke generated after heating passes through a filter mechanism
and then is divided into multiple groups to increase the contact area between the
smoke and the filter, so as to cool the smoke. Then, the smoke enters the empty tube
zone (1-3) to be cooled again, so that the temperature of the smoke is lowered to
a moderate temperature for the human body, which greatly improves user experience.
The novel electronic cigarette cartridge of the present invention has a simple structure,
and can realize fully automated production during production, which greatly reduces
product costs.

TECHNICAL FIELD
[0001] The present invention relates to the field of electronic cigarettes, in particular to a novel electronic cigarette cartridge.
BACKGROUND
[0002] China is the largest tobacco consumer and producer in the world, and China is one of the countries having the largest number of smokers. However, it is well known that smoking is harmful to health. Traditional cigarettes will produce tar and other poisonous substances under a high temperature (600°C-800°C). These poisonous substances not only irreversibly damage the respiratory system of humans, but also lower the immune response of humans, which causes human to suffer from serious diseases. In view of this, heat-not-burn products are developed, especially, the heat-not-burn products with herbs rather than tobacco are superior to those ordinary heat-not-burn tobacco products.
[0003] Currently, herbal cigarette cartridges available on the market have the following shortcomings: the smoke concentration is low during use, the herbal granules are likely to fall out of the heating zone, the smoke may burn the mouth due to its excessively high temperature, and the herbal cigarette cartridges have difficulties in automated production.
SUMMARY
[0004] The shortcomings of the heat-not-burn cigarette cartridges identified in the prior art include the smoke concentration is low during use, the herbal granules are likely to fall out of the heating zone, the smoke may burn the mouth due to its excessively high temperature, and the herbal cigarette cartridges have difficulties in automated production.
[0005] In view of the above-mentioned problems, the present invention provides a novel electronic cigarette cartridge. In use, the heat in the heating zone is well retained, and the herbal granules will not fall out of the heating zone. The smoke generated after heating passes through a filter mechanism and then is divided into multiple groups to increase the contact area between the smoke and the filter, so as to cool the smoke. Then, the smoke enters the air tube to be cooled again, so that the temperature of the smoke is cooled to a moderate temperature for the human body, which greatly improves user experience. The novel electronic cigarette cartridge of the present invention has a simple structure, and can realize fully automated production during production, which greatly reduces production costs.
[0006] The present invention provides a novel electronic cigarette cartridge, including a heating zone, a filter plug, an empty tube zone, a filter cotton, a peripheral paper tube and a granule sealing paper. The heating zone is filled with granules, and the granule sealing paper is provided at the front end of the heating zone. The filter plug is located between the heating zone and the empty tube zone, and the filter cotton is provided at the rear end of the empty tube zone. The peripheral paper tube surrounds the outer peripheries of the heating zone, the filter plug, the empty tube zone and the filter cotton.
[0007] Further, the filter plug is provided with a vent channel. In this way, the smoke passing through the filter plug can be grouped by the vent channel to increase the contact area between the smoke and the filter plug to improve the filtering effect.
[0008] Further, both ends of the filter plug are provided with chamfers. In this way, the filter plug can play a guiding role when assembled in the peripheral paper tube, thereby realizing automated production.
[0009] Further, the filter plug is made of rubber or a silica gel material, and the filter plug is in an interference fit with the inner wall of the peripheral paper tube. In this way, the herbal granules will not fall into the empty tube zone, and the heat in the heating zone is retained during use, thereby increasing the produced amount of smoke. When being inhaled, the smoke is grouped and enters the empty tube zone only through the vent channel in the filter plug.
[0012] Further, the filter cotton is made of polyester fibers or an organic cotton material, and the filter cotton is in an interference fit with the inner wall of the peripheral paper tube. In this way, in use, the smoke enters the empty tube zone and then is mixed with the air in the empty tube zone, and is thus cooled. Further, the granules are herbal granules.
[0013] The present invention has the following technical effects. The filter plug is employed to retain the heat in the heating zone during use, thereby increasing the produced amount of smoke. The filter plug is employed to prevent herbal granules from falling into other zones, and to group the smoke through the small holes in the filter plug to enter the empty tube zone. By arranging the filter plug, the contact area between the smoke and the filter is increased to improve the effect of cooling the smoke. The empty tube zone is designed to mix smoke and air to cool the smoke. The filter plug is provided with chamfers for guidance, thereby realizing automated production.
BRIEF DESCRIPTION OF THE DRAWINGS
[0014]
FIG. 1 is a cross-sectional view of the structure of a novel electronic cigarette cartridge of the present invention; and
FIG. 2 is a schematic view of the internal structure of the novel electronic cigarette cartridge of the present invention.
DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The present invention will be further described below with reference to the drawings and embodiments.
Embodiment 1
[0017] As shown in FIG. 1, 1-1 represents the heating zone, wherein the herbal granules are located in the heating zone, 1-2 represents the filter plug, 1-3 represents the empty tube zone, 1-4 represents the peripheral paper tube, and 1-5 represents the filter cotton, 1-6 represents the granule sealing paper.
[0018] As shown in FIG. 1, the filter plug 1-2 is made of rubber or a silica gel material, and is in an interference fit with the inner wall of the paper tube 1-4 to prevent granules from falling into the empty tube zone, while preventing the heat in the heating zone from dissipation during use, thereby increasing the produced amount of smoke. When being inhaled, the smoke can only enter the empty tube through the small holes in the filter plug.
[0019] As shown in FIG. 2, 2-1 represents the vent channel of the filter plug, the passing smoke is grouped by the vent channel to increase the contact area between the smoke and the filter plug to improve the filtering effect.
[0020] As shown in FIG. 1, the filter cotton 1-5 is made of polyester fibers or an organic cotton material, and is in an interference fit with the inner wall of the peripheral paper tube 1-4. In use, the smoke enters the empty tube zone 1-3 and is then mixed with the air in the empty tube zone 1-3, and is thus cooled.
[0021] As shown in FIG. 1, since the filter plug 1-2 is in an interference fit with the inner wall of the peripheral paper tube 1-4, the filter plug 1-2 is provided with chamfers to play a guiding role when assembled in the peripheral paper tube1-4, thereby realizing automated production.
