Description

Technical Field

[0001] The present invention relates to the field of aerosol generating articles, and particularly to a multifunctional aerosol generating article. Background Art

[0002] With the improvement of living standards and the continuous enhancement of people's health awareness, people's attention to "health-related" aerosol products has been increasing. Major domestic and foreign enterprises have developed various new types of heated aerosol generating articles to replace traditional cigarettes in order to meet the changing consumer demands.

[0003] A heat-not-burn product heats an aerosol generating matrix section at a temperature within 300 degrees through a special heat source. When heated, the flavor substances in the aerosol generating matrix section volatilize to produce aerosol to meet the needs of smokers. Different from traditional cigarettes, the aerosol generating matrix section of the heat-not-burn aerosol generating article is in a non-combustion state during suction, so that harmful components generated by high-temperature combustion and cracking of the aerosol generating matrix can be reduced.

[0004] Currently, aerosol generating articles mainly have two forms: wrapped rolling and integrated filling. For integrated filling, an integrated tube body with a certain hardness and wall thickness is selected as the outer tube, and then the aerosol generating unit, the support and barrier unit, the cooling and filtering unit, etc. are filled into the tube body in sequence by filling. Due to the more diverse forms of the aerosol generating unit of the integrated filling type aerosol generating article, it is not limited to the filamentous or sheet-like form convenient for rolling, and there is no need to use rolling equipment, and the preparation method is simple, etc., it has gradually become the focus of people's attention.

[0005] The end face of the tube body on one side of the aerosol generating unit of the aerosol generating article in the prior art is breathable, which allows gas to pass through and enter the aerosol generating unit. In this way, the air introduced from the outside carries the aerosol generated by the aerosol generating unit during the suction process and enters the consumer's mouth together. That is to say, the outer tube of the existing integrated filling type aerosol generating article does not have ventilation holes, but intakes air through the end face on the side of the aerosol generating matrix. However, since the aerosol generating unit contains the introduced air and the oxygen concentration is high, the heating temperature must be lower than 300 °C, otherwise there is a risk of combustion. Therefore, the concentration of the aerosol entering the consumer's mouth at this heating temperature is low. In addition, the existing aerosol heating devices include ordinary aerosol heating devices that allow air to enter the aerosol generating unit and oxygen-poor aerosol heating devices that do not allow air to enter the aerosol generating unit. Correspondingly, the aerosol generating article can only be applicable to a certain type of aerosol heating device and cannot be universally compatible.

[0006] Therefore, it is desired to develop an integrated filling type aerosol generating article that can ensure the aerosol concentration and is also applicable to two types of aerosol heating devices.

[0007] To solve the above problems, the present invention is proposed. Summary of the Invention

[0008] The present invention provides a multifunctional aerosol generating article, which includes a tube body 5, and an aerosol generating unit 1, a barrier section 2 and a filter section 4 filled in the tube body 5. One end face of the tube body 5 on the side of the aerosol generating unit 1 has a sealing member 6; the sealing member 6 is breathable;

[0009] A cavity is reserved between the barrier section 2 and the filter section 4 as a functional section 3;

[0010] The tube body 5 at the functional section 3 has a first ventilation hole 31 that penetrates through the tube body 5;

[0011] The outer side of the tube body 5 also has a sleeve 7, and the sleeve 7 has a second ventilation hole 71. The sleeve 7 can be pushed and pulled relative to the tube body 5, so that the second ventilation hole 71 and the first ventilation hole 31 are switched between being opposite and misaligned.

[0012] Preferably, the axial heights of the first ventilation hole 31 and the second ventilation hole 71 are the same, and the sleeve 7 can be rotated relative to the tube body 5, so that the second ventilation hole 71 and the first ventilation hole 31 are switched between being opposite and misaligned. Alternatively, the axial heights of the first ventilation hole 31 and the second ventilation hole 71 are different, and the sleeve 7 can be axially moved relative to the tube body 5, so that the second ventilation hole 71 and the first ventilation hole 31 are switched between being opposite and misaligned. That is to say, the relative movement mode between the two can be rotation or axial push-pull.

[0013] Preferably, the multifunctional aerosol generating article means that, in the first function, the second ventilation hole 71 is opposite to the first ventilation hole 31, allowing external air to enter the aerosol generating article through the second ventilation hole 71 and the first ventilation hole 31. The sealing member 6 is breathable. After the aerosol generating article is inserted into the aerosol heating device, a sealing member is provided at the contact portion of the aerosol heating device with the sealing member 6 to seal the sealing member 6, so as to ensure that air cannot enter the aerosol generating unit 1 through the sealing member 6;

[0014] In the second function, the second ventilation hole 71 is misaligned with the first ventilation hole 31, and external air is not allowed to enter the aerosol generating article through the second ventilation hole 71 and the first ventilation hole 31. The sealing member 6 is breathable, and air enters the aerosol generating unit 1 through the sealing member 6.

[0015] Preferably, there is a functional section 3 between the barrier section 2 and the filter section 4.

[0016] The functional section 3 is a separate cavity structure or the cavity is filled with functional materials; the functional materials are selected from one or more of cooling materials, flavoring materials, or filtering materials, and the form of the functional materials is one or several of bursting beads, granules, sustained-release gels, powders, pastes, and disordered materials. Preferably, the purpose of the functional materials is to reduce the temperature of the aerosol, flavor the aerosol, and reduce the harmful components in the aerosol. The functional materials are selected from, but not limited to, diatomaceous earth, flavor granules, activated carbon, heat-conducting gels, hydrated salt cooling materials, and waxy materials.

[0017] Preferably, the axial positions of the second ventilation holes 71 and the first ventilation holes 31 are between the end face of the functional section 3 close to the filtering section 4 and the end face of the aerosol generating unit 1 close to the barrier section 2.

[0018] More preferably, the axial positions of the second ventilation holes 71 and the first ventilation holes 31 are in the functional section 3 and close to the barrier section 2. That is to say, the second ventilation holes 71 and the first ventilation holes 31 can be arranged at any positions of the barrier section 2 and the functional section 3, but more preferably, the second ventilation holes 71 and the first ventilation holes 31 are on the functional section 3 and are closer to the barrier section 2 axially.

[0019] Preferably, after the aerosol generating article is inserted into the aerosol heating device, the axial height of the second ventilation holes 71 and the first ventilation holes 31 is lower than the axial height of the highest point of the heating element of the aerosol heating device. The purpose of limiting the axial height of the second ventilation holes 71 and the first ventilation holes 31 to be lower than the axial height of the highest point of the heating element of the aerosol heating device here is that it is more suitable for an aerosol heating device with oxygen-deficient heating, the generated aerosol concentration is higher, the aroma is more intense, and the sensory evaluation of puffing is higher.

[0020] Preferably, the outer diameter of the tube body 5 is less than or equal to the inner diameter of the sleeve 7.

[0021] Preferably, the diameter of the first ventilation holes 31 can be 0.01 - 3.5 mm, and the number is 1 - 35, and the diameter of the second ventilation holes 71 can be 0.01 - 3.5 mm, and the number is 1 - 35. More preferably, the sizes and numbers of the second ventilation holes 71 and the first ventilation holes 31 are the same.

[0022] Preferably, the second ventilation holes 71 and the first ventilation holes 31 are formed by laser drilling or mechanical drilling through the tube body 5. The drilling method is not limited herein, as long as it can drill holes in a tube body with a certain thickness and hardness, and the drilling method can also be selected according to the material of the tube body. The second ventilation holes 71 and the first ventilation holes 31 can be pre-drilled before each section of the tube 5 is filled, or can be drilled after filling is completed. The meaning of pre-drilling is to drill holes in the tube body 5 when the aerosol generating unit 1, the barrier section 2, and the filter section 4 are not filled in the tube body 5.

[0023] Preferably, an outer layer of the tube body 5 is further wrapped with a label paper, the purpose of which is for aesthetics and to prevent the aerosol generating material in the tube body 5 from leaking outside the paper tube. If the pre-drilling method for the tube body 5 is adopted, preferably, the label paper can be wrapped on the outer layer of the tube body 5 and then drilled. When drilling, both the label paper and the tube body 5 need to be drilled through to introduce outside air into the aerosol generating article.

[0024] Preferably, the sealing member 6 is breathable. The sealing member 6 can be selected from breathable materials and breathe through itself, or can be selected from non-breathable materials and breathe through drilled holes; the breathable materials are selected from but not limited to paper materials or inorganic porous materials, and the inorganic porous materials are selected from but not limited to alumina, silicon carbide, silicon nitride, or diatomaceous earth; the non-breathable materials are resinous materials, and the resinous materials are selected from but not limited to PEEK, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, or polylactic acid.

[0025] The key point emphasized by the present invention is that the aerosol generating article can be applicable to both an oxygen-deficient heating type aerosol heating device and an existing ordinary intake air heating type aerosol heating device. To achieve the conversion of the two functions, it is necessary to cooperate with whether the sealing member 6 and the second ventilation holes 71 and the first ventilation holes 31 allow gas to pass through.

[0026] When the aerosol generating article with ventilation holes is heated by the existing ordinary intake air, the sealing member 6 is breathable, which allows gas to pass through it and enter the aerosol generating matrix, while the second ventilation holes 71 and the first ventilation holes 31 are misaligned and do not allow outside air to enter the aerosol generating article through the second ventilation holes 71 and the first ventilation holes 31.

[0027] When an aerosol generating article with ventilation holes uses oxygen - depleted heating, after the aerosol generating article is inserted into the aerosol heating device, there is a seal at the contact point between the aerosol heating device and the sealing member 6 to seal the sealing member 6, so as to ensure that air cannot enter the aerosol generating unit 1 through the sealing member 6. The second ventilation hole 71 is opposite to the first ventilation hole 31, allowing external air to enter the aerosol generating article through the second ventilation hole 71 and the first ventilation hole 31.

[0028] Preferably, the filter section 4 is a common filter element, selected from paper materials, polylactic acid, acetate fiber, cotton, resin; or a special filter element, selected from hollow mouthpieces, concentric - circle filters, grooved filters, colored filters, and filters with popping beads.

[0029] Preferably, the aerosol generating unit 1 is an aerosol generating matrix in the form of particles, powders, filaments, gels or pastes. Here, it is only an example to illustrate the form of the aerosol generating matrix, but in fact, it is not limited to the above - mentioned forms, as long as the aerosol generating matrix can be loaded into the inside of the tube body 1 is applicable.

[0030] Preferably, the tube body 5 is selected from, but not limited to, paper tubes.

[0031] Preferably, the aerosol generating article further includes an end cavity, which is located at the end near the lip end side, and the end cavity is defined by the tube body. When sucking, some smokers will have doubts about the safety of directly contacting the filter material of the cigarette filter section. The purpose of the end cavity of the aerosol generating article of the invention is that the smoker's mouth only contacts the tube body and does not contact the filter material, eliminating the above - mentioned doubts of some smokers and better protecting the filter unit.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In the prior art, holes are usually punched in the tipping paper or forming paper of the rolled aerosol generating article. There is no research on punching holes in the outer wall of the hard paper tube of the integrated filling type aerosol generating article. The present invention overcomes the existing technical prejudice and first thinks of punching holes in the hard pipe material of the integrated filling type aerosol generating article.

[0034] 2. The outer side of the tube body 5 of the present invention further has a sleeve 7, and the sleeve 7 has a second ventilation hole 71. The sleeve 7 can rotate relative to the tube body 5, so that the second ventilation hole 71 and the first ventilation hole 31 are switched between relative and misaligned positions. That is to say, it can be realized to switch between allowing air to enter the functional section 3 and not allowing air to enter the functional section 3, so as to ensure that it is applicable to both oxygen - depleted aerosol heating devices and ordinary aerosol heating devices.

[0035] The first function: when it allows air to enter the functional section 3, the aerosol generating article can be used in an oxygen-deficient aerosol heating device. At this time, after the aerosol generating article is inserted into the aerosol heating device, there is a seal at the contact between the aerosol heating device and the sealing member 6 to seal the sealing member 6, so as to ensure that air cannot enter the aerosol generating unit 1 through the sealing member 6; this makes the aerosol generating unit 1 in an oxygen-deficient state. Even when the temperature reaches above 300 °C, combustion will not occur. In this way, it can be ensured that the aerosol generating unit 1 can be heated to a higher temperature, thereby generating a high concentration of aerosol. The second air vent 71 at the functional section 3 and the first air vent 31 introduce air, and the air converges at the functional section 3. Here, the air has the effect of extracting the aerosol generated by the aerosol generating unit 1, which can ensure the aerosol concentration. In addition, when the heating temperature is greater than 300 °C, combustion still does not occur. A higher heating temperature is conducive to fully realizing the release of aroma and increasing the aroma amount. The heat loss is small, the heating efficiency is higher, and the sensory evaluation is better.

[0036] The second function: when it does not allow air to enter the functional section 3, the aerosol generating article can be used in a general aerosol heating device, and external air enters the aerosol generating unit 1 through the sealing member 6. In this case, a wider range of aerosol heating devices can be used. Description of the Drawings
