Description
Technical Field
The invention belongs to the technical field of novel tobaccos, and particularly relates to a cigarette structure of a heating nonflammable cigarette.
Background
The main characteristic of the heating non-burning type cigarette is that the heating temperature of the non-burning type cigarette is lower than 350 ℃, and only a small amount of second-hand smoke is generated in the heating process, so that the attention of various large tobacco companies in China and abroad is obtained, and the heating process becomes a hot spot of current research. The existing smoking articles of the heated non-combustible cigarettes are divided into cut tobacco type and sheet type, cut tobacco type fillers are cut tobacco or cut tobacco stems, and the conventional cigarette technology is adopted, and the cut tobacco type fillers are formed by a cigarette machine; the sheet filler is tobacco sheet, and is prepared into sheet filaments by adopting a composite technology, and the sheet filaments are formed by a multi-element chewing rod composite tipping machine. The current filler of the cigarette smoke section is filiform due to the characteristics of the tobacco shred process and the flake process. The conventional heating non-combustible cigarette heater is divided into two types of plug-in heating and non-plug-in wrapping heating, and the plug-in heating is performed in a mode of heating by inserting a pin-type or sheet-type heating body into a smoking article in a cigarette. After the consumer sucks and uses, the coked smoking articles in the cigarettes can adhere to the pin-type or sheet-type heating body and remain in the heating cavity of the heater, so that peculiar smell and more harmful ingredients are released during the second suction. The retention of the smoking article also makes the second heating temperature transfer poor, while making cleaning extremely inconvenient, reducing user experience and product safety. Residues are accumulated in the heater for a long time, so that the heater is extremely easy to scale and damage, and the service life of the heater is reduced. In addition, if the cigarette is a shredded cigarette or a cut stem heated non-combustible cigarette, the cigarette can only be applied to a needle type heating appliance or a wrapped type heating appliance, because when the blade type heating body is inserted into the cigarette, the smoke-producing product at the front end of the cigarette is easily pushed into the hollow section of the rear section of the smoke-producing product due to the large resistance, so that the hollow section is blocked, the smoke resistance of the cigarette is increased, and a consumer cannot suck the heated aerosol.

Preferably, the temperature control section is a spiral temperature control spring wrapped with polylactic acid fibers, and the diameter of the temperature control spring is smaller than or equal to the inner diameter of the winding drum.
Compared with the prior art, the invention has the following beneficial effects:
1. The front section of the cigarette structure adopts the cylindrical isolation member provided with the heating body insertion opening, and the isolation member can isolate the smoking article and prevent tiny parts in the smoking article from falling into the heating cavity of the heater in the heating process and after coking, so that the cleaning of the heating cavity is ensured.
2. The preferred pin-type heating body inserting hole of the invention adopts a horn shape, and the sheet-type heating body inserting groove adopts a wedge-shaped structure, so that the heating body (pin-type heating body or sheet-type heating body) is easier to enter when being inserted into cigarettes, and the heating body is prevented from being damaged due to improper use.
3. The narrowest part of the heating body inserting opening (needle type heating body inserting hole or sheet type heating body inserting groove) is slightly larger than the size of the heating body (needle type heating body or sheet type heating body), so that the heating body can receive the scraping action of the heating body inserting opening when withdrawing cigarettes, and coking matters adhered to the heating body are cleaned and prevented from being adhered to the heating body.
4. The cigarette can be matched with a heating appliance with a needle type heating body or a heating appliance with a sheet type heating body. When other special-shaped heating bodies appear, the shape of the heating body inserting opening on the isolating component can be adjusted and changed along with the special-shaped heating bodies so as to adapt to the requirements of the shape of the special-shaped heating bodies.
5. The invention is provided with the suction resistance adjusting air hole and the air supplementing air hole, can adjust the suction resistance and supplement air intake when the cigarette is sucked by adjusting the total opening area of the suction resistance adjusting air hole, ensures that the oxygen supply is sufficient when the cigarette is heated, has ideal suction resistance, and improves the suction feeling of consumers.
6. According to the invention, by arranging the limiting section, the problem that the heating effect is affected due to insufficient contact between the heating body and the smoking article caused by extruding the smoking article (particularly the coiled wire-shaped smoking article) in the winding drum into the rear section of the cigarette when the heating body (particularly the blade-type heating body) is inserted into the cigarette can be well prevented, and the problem that the aerosol channel is blocked due to extrusion deformation of the smoking article can be effectively relieved. Meanwhile, the limiting section is provided with a plurality of holes, so that the position of the smoking article can be limited, and meanwhile, the gas mist can be effectively conveyed, and the design is quite reasonable.
7. According to the invention, the temperature control section is arranged, so that the hollow pipeline can not deform when the polylactic acid fiber blocks part of the aerosol channels due to deformation caused by heat absorption due to the characteristics of the hollow pipeline, and the function of normally conveying the aerosol can be achieved. Therefore, the temperature of the aerosol can be effectively controlled and reduced, and the problem that the aerosol channel is blocked by the thermal deformation of the polylactic acid fiber is solved.
8. According to the invention, the temperature of the aerosol in the central part of the cigarette is effectively reduced by arranging the holes on the pipe wall of the hollow pipeline in the temperature control section. When the heated aerosol with heat is transferred to the rear section (sucking end) of the cigarette through the limiting section, the heat in the aerosol near the side wall of the winding drum in the cigarette is absorbed by the heat absorbing fiber on the temperature control section at the corresponding position in the cigarette, meanwhile, the fiber gradually deforms to block part of the aerosol channel, and when the hotter aerosol which is not contacted with the heat absorbing fiber in the central part of the cigarette passes through the hollow pipeline, the heat energy in the aerosol is continuously absorbed by the heat absorbing fiber at the position corresponding to the opening on the pipe wall, so that the cooled aerosol can be normally continuously transferred to the sucking end of the cigarette through the pipeline.
9. The invention mainly cooperates with the temperature control section to jointly reduce the temperature of the aerosol by arranging the hollow section. Meanwhile, the unit which can be flexibly arranged at the rear section of the cigarette can not only play a role in cooling, but also have the roles of reducing suction resistance, dredging aerosol and providing a movable space for a limiting section or a temperature control section.
10. The invention is provided with a plurality of sheet heating body inserting grooves, so that consumers can conveniently insert the sheet heating bodies into cigarettes. When the structure of the plurality of sheet type heating body inserting grooves is adopted for heating, the redundant sheet type heating body inserting grooves can play a role in guiding air together with the suction resistance adjusting air holes, and can also replace the suction resistance adjusting air holes to directly play a role in guiding air.
11. The product of the invention can use various smoking articles such as strip smoking articles, filament smoking articles, granular smoking articles and the like as raw materials, is less influenced and limited by the raw materials, thereby being suitable for various production environments and reducing the production and manufacturing cost.
12. When the limit section adopts the limit spring made of metal materials, relatively more smoke heat energy can be absorbed by adjusting the density of the spiral ring of the limit spring, and the limit section has a limit function. The limit spring has elasticity, so that the pressure of pushing the heating body to the rear section of the cigarette, which is generated when the heating body is inserted into the smoking article, can be absorbed, and the smoking article is not extruded, deformed and accumulated together to cause poor contact with the heating body or partially block the smoke passage. When the heating body is inserted in place, its rebound force will cause the smoking article (in particular the tobacco thread) pressed to be displaced towards the rear section to be pushed back into position, thereby maintaining good contact with the heating body.
13. When the temperature control section adopts a metal spiral spring wrapped with polylactic acid fibers or other heat absorption fibers, the inside of the spring is a hollow channel, so that the aerosol can be effectively conveyed, and meanwhile, when the aerosol passes through the spiral spring cooling section, the heat in the aerosol can be absorbed by the polylactic acid fibers and the metal materials at the same time, and the corresponding aerosol heat can be absorbed by adjusting the diameter and the length of the spiral spring and the density of the polylactic acid fibers wrapped on the spiral spring according to the needs, so that the temperature control section is a scientific and effective temperature control means.
14. When the acetate fiber filter stick with the polylactic acid powder or particles uniformly added is adopted in the temperature control section, when the hotter aerosol passes through the section, the heat in the aerosol is preferentially absorbed by the polylactic acid powder in the acetate fiber, and the polylactic acid powder generates phase transition to gradually melt and deform when absorbing heat energy, but the acetate fiber cannot deform and still can keep good aerosol trafficability, so that the normal flow of the smoke can be ensured while the temperature of the smoke is reduced, and the conveying channel of the smoke cannot be blocked.
