Description

TECHNICAL FIELD The present invention belongs to the field of heat-not-burn cigarettes, and specifically relates to heat-not-burn cigarettes with adjustable air permeability and vent position on the tube wall, and a method for adjusting them.

As smokers become more health conscious and demand a more personalized tobacco product experience, the tobacco industry has developed a variety of heat-not-burn cigarettes with reduced tar and harmful substances to meet the increasing demands of smokers. Non-combustion heated tobacco can satisfy a smoker's sensory desire for tobacco products and provide a healthier smoking experience because the tobacco heating method is different from traditional cigarette products.

A conventional heat-not-burning cigarette mainly comprises a smoking wick, a hollow support, a cooling part, and a filter. In order to introduce air, increase ventilation, and effectively lower the temperature of the smoke, the hollow support of the heat-not-burnable cigarette is generally perforated by an online laser perforation method, and the tube wall of the hollow support and the molding paper and tipping paper wrapped around the hollow support are perforated to form vent holes for introducing air. However, this method has the following drawbacks: 1. Online laser perforation requires high requirements for the material and thickness of the hollow support tube wall. The material of the hollow support tube wall must not be damaged during online laser perforation, and the hollow support tube wall must not be particularly thick so as not to be unpierceable during online laser perforation; 2. Online laser perforation requires high laser power; 3. At present, the hollow support and the molding paper and tipping paper wrapped around the hollow support are perforated to form ventilation holes, so that the outside air directly enters the interior of the hollow support through the ventilation holes, and the air is introduced through the ventilation holes at a high speed, and the contact area between the introduced air and the smoke is limited. There is a problem that the

In addition, when the tube wall of the heated cigarette is ventilated by a physical perforation method, there is a problem that the ventilation amount cannot be adjusted and the ventilation position is fixed. When air is introduced through physical perforations, ambient air is introduced through the perforations and the temperature is lowered, so the amount of ventilation is determined by the size of the perforations. However, as the material of the smoking section changes, or the corresponding smoking device changes, it becomes desirable to be able to adjust the ventilation rate and ventilation location of the heated tobacco.

Therefore, there is a demand for a heat-not-burn cigarette capable of adjusting the amount and degree of ventilation, which can ensure the amount of smoke and quality of smoke while ensuring the effect of lowering the temperature of the smoke.

The present invention is presented to solve the above problems.

A first aspect of the present invention comprises a smoking section 1 and a heated cigarette filter having a natural ventilation function, both of which are wrapped with a forming paper 4, and further has a tipping paper 5 in at least a partial region outside the forming paper 4 around which the heated cigarette filter having a natural ventilation function is wrapped,
A heated cigarette filter having a natural ventilation function from a far lip end to a near lip end includes a smoke extraction part 2 and a filter plug part 3 in sequence, the smoke extraction part 2 itself having a ventilation function, and outside air can enter the inside of the heated cigarette through the smoke extraction part 2,
Only a part of the smoke extracting part 2 is wrapped with the tipping paper 5, and only the forming paper 4 is wrapped around the outside of at least a partial region of the smoke extracting part 2 on the side near the smoke generating part 1, without the tipping paper 5 wrapped.
The forming paper 4 is breathable, the tipping paper 5 is non-breathable, and the length and position of the tipping paper 5 are adjustable to provide a heated cigarette with adjustable air permeability and ventilation position of the tube wall.

Preferably, the smoke extraction part 2 is a hollow structure with a tube wall 21 and a hollow part 22, the tube wall 21 does not need to be perforated, and has a ventilation function by itself. Here, the cross-sectional area of the hollow portion 22 is not limited to a circular shape, and may be an arbitrary shape such as a triangle, a polygon, or a star.

Preferably, the tipping paper 5 covers 1/6 to 5/6 of the axial length of the smoke extractor 2 .

Preferably, the air permeability of the forming paper 4 is 1000-10000 CU.

Preferably, the tube wall 21 is press-molded with the particles bound together, and the voids between the particles after molding serve as ventilation holes, so that the tube wall 21 itself has a ventilation function,
The particles have a particle size of 200 to 25,000 μm, and after the particles form the wall of the hollow tube, the thickness of the tube wall 21 is 1.0 to 2.0 mm, and the voids between the particles in the tube wall 21 are dispersed, and the porosity is 50 to 80%.

Preferably, the particles are selected from organic or inorganic particles, the inorganic particles comprising aluminum oxide, zirconium oxide, calcium carbonate, glass beads, silicon dioxide, iron, copper, aluminum, gold, platinum, spherical magnesium silicate or calcium sulfate, the organic particles comprising cellulose acetate, cellulose acetate propionate, cellulose acetate butyrate, microcrystalline cellulose, sucrose powder, dextrin, lactose, sugar powder, glucose, mannitol, starch, methylcellulose, ethylcellulose. , polylactic acid, polyethylene, polypropylene, polyhydroxybutyric acid, polyε-caprolactone, polyglycolic acid, polyhydroxyalkanoate, and starch-based thermoplastic resin.

Preferably, the tube wall 21 is cellulose acetate tow, in which case the filling amount of cellulose acetate tow is regular, and the thickness of the tube wall 21 is 1.0-3.0 mm after the cellulose acetate tow forms the tube wall of the hollow tube. In this case, a regular filling amount of cellulose acetate tow means that 2000 to 4500 filaments are filled when the circumferential length of the filter is 19.8 mm.

Preferably, tube wall 21 is a breathable ceramic.

In other words, in the structure of this heat-not-burning cigarette, the forming paper 4 plays two winding roles: (1) winding the smoke extraction part 2 and the filter plug part 3 together to form a heat-not-burning cigarette filter having a natural ventilation function; The tipping paper does not play the role of winding, but plays the role of controlling the length of the tipping paper to control the ventilation amount and the ventilation position of the smoke extraction part 2, and to print a pattern, LOGO, and the like.

The second aspect of the present invention provides the method for adjusting the heat-not-burn cigarette, in which the air permeability and air ventilation position of the pipe wall are adjustable according to the first aspect of the present invention, wherein the size and position of the region covering the smoke extraction part 2 of the tipping paper 5 are adjusted to adjust the air permeability and the air ventilation position of the smoke extraction part 2, thereby adjusting the air permeability and the air ventilation position of the heat-not-burn cigarette.

In addition, the heated cigarette filter with natural ventilation function of the present invention is not limited to having only the smoke extraction part 2 and the filter plug part 3, but may have a ternary composite structure according to actual needs, and may further include other functional parts such as a support part, a temperature lowering part, and a flavor enhancing part.
Effect of the invention

The beneficial effects of the present invention compared to the prior art are as follows.
1. The heat-not-burn cigarette of the present invention, in which the air permeability of the tube wall and the air-flow position can be adjusted, has a smoke extraction part 2 that itself has a ventilation function. Outside air can enter the inside of the heat-not-burn cigarette through the smoke extraction part 2. Only a part of the smoke extraction part 2 is wrapped around the tipping paper 5, and only the forming paper 4 is wrapped around the outside of the partial area of the smoke extraction part 2 near the smoke generating part 1, the forming paper 4 is air permeable, and the tip paper 5 is non-air permeable. Since the length and position of the tipping paper 5 are adjustable, the air permeability and position of the heated cigarette can be adjusted by adjusting the size and position of the area covering the smoke extraction part 2 of the tipping paper 5 to adjust the air permeability and the position of the smoke extraction part 2. - 特許庁By controlling the length of the tipping paper 5, the cigarette structure of the present invention allows for more flexible control of the amount and position of ventilation in the smoke extraction section 2. FIG.
2. The heated cigarette filter with natural ventilation function of the present invention has a smoke extractor 2. The tube wall 21 of the smoke extractor 2 does not need to be perforated. The tube wall of the smoke extraction part 2 can be ventilated, and the outside air enters the inside of the heated cigarette through the air gap and is mixed with the smoke, so that the purpose of introducing air into the inside of the heated cigarette is achieved, and there is no need to make a hole.
3. In a preferred embodiment of the present invention, the tube wall 21 is formed by pressing and bonding particles, and the voids between the particles after forming play a role of natural ventilation. After the particles form a hollow tube, the voids between the particles in the tube wall are distributed. , The introduced air and smoke are uniformly mixed, and in the prior art, perforation can only ensure that a large amount of air is introduced to achieve the cooling effect, but the problem that the air and smoke cannot be uniformly mixed and the smoke quality is poor is solved.
4. When the particles are used as the solid temperature-lowering part, the temperature-lowering effect is excellent, but in order for the smoke to reach the filter and be inhaled by the smoker, it is necessary to pass through the voids of the particles in the solid temperature-lowering part, which increases the amount of smoke absorbed by the solid temperature-lowering part. In the present invention, air is introduced to reduce the temperature of smoke, and the selection of the particle material is also very important. The particle material of the present invention is selected from materials that have a temperature-lowering effect, so that when the smoke passes through, the material of the pipe wall of the smoke extraction part can also play a role in reducing the temperature of the smoke.
5. In a preferred embodiment of the present invention, the tube wall 21 is made of cellulose acetate tow, and this cellulose acetate tow is not the cellulose acetate tow for conventional filters. In the present invention, the cellulose acetate tow used for the tube wall 21 is regular tow, so the cellulose acetate tow itself has voids and is breathable like a screen door with mesh. Compared to directly perforating the temperature-lowering part, in the present invention, the air introduced into the smoke extraction part made of cellulose acetate tow is more dispersed, and the amount of air introduced can achieve temperature-lowering, and the air can be uniformly introduced into the heated cigarette, so that the introduced air and smoke are uniformly mixed. Fixed the problem of poor quality.
6. In a preferred embodiment of the present invention, the tube wall 21 can be made of breathable ceramic, which has a natural ventilation function and can also play a supporting role.
