Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of heated cigarettes, and particularly relates to a smoking segment, a manufacturing method and use thereof. BACKGROUND

[0002] With the improvement of living standards, people pay more and more attention to their own health problems, and in recent years, the concern about smoking health problems is high. In order to meet the changing consumer demand, major domestic and foreign enterprises have developed various low-hazard heated cigarettes.

[0003] Heated cigarettes are heated by the smoking segment of the cigarette to produce smoke, and the acceptance of the taste of the smoke is good. The current marketable heated non-combustible cigarette mainly includes a smoking segment, a hollow support segment, a cooling segment and a filter segment. The form of tobacco in the smoking segment includes ordered or unordered reconstituted tobacco leaf sheet, tobacco shreds, granular tobacco material and blocky tobacco material. When the tobacco in the smoking segment is heated, the flavoring and smoking agent loaded thereon are evaporated to produce smoke.

[0004] The commonly used heating methods in the prior art include resistance heating type methods using central heating elements or circumferential heating elements, and electromagnetic type heating methods, but there are the following problems:

[0005] 1. The heated cigarette has a hollow support segment, a cooling segment and a filter segment, so the whole cigarette is relatively long and occupies a large space, which is not convenient to carry;

[0006] 2. The central heating element is inserted into the smoking segment to heat the smoking material. After the heating element is inserted, the smoking material is heated only by the thermal radiation of the heating element. Since the radial distance of the smoking material from the heating element is different, the heating is not uniform. In addition, the smoking material close to the heating element is easily overheated and scorched to produce harmful substances. The central part of the heating element is easily overheated and scorched and adheres to the heating element, which damages the heating element and affects the heating effect;

[0007] 3. In addition, if the central heating element is inserted into the smoking segment to heat the smoking material, the smoking material is easily displaced when the heating element is inserted;

[0008] 4. If the circumferential heating element is used to heat the cigarette in the circumferential direction, the heat needs to pass through the cigarette paper from the outside to the inside of the cigarette. This heating method is low in efficiency, and a large amount of heat is lost to the smoking set outside the circumferential heating element. And this method still has the problem that the radial distance of the smoking material from the heating element is different, so the heating is not uniform;

[0009] 5、If using electromagnetic heating method: method 1 is that the inner layer of cigarette paper is coated with ferromagnetic material as a whole, which still belongs to circumferential heating and still has the problem of uneven heating of smoking substance; method 2 is that ferromagnetic particles are mixed in the smoking substance, which can solve the problem of uneven heating of smoking substance, but the preparation method of the smoking substance needs to be greatly changed and the problem of uniform mixing of ferromagnetic particles and smoking substance needs to be considered, which greatly changes the production process of the existing smoking substance.

[0010] When the smoking substance is a particle, the existing technology usually fills the smoking segment in the cigarette with a particle-type smoking substance, and inserts a central heating element into the smoking segment for heating, which brings some problems:

[0011] A, after the heating element is inserted, the smoking particles are heated only by the heat radiation of the heating element, and since the radial distance of the smoking particles from the heating element is different, uneven heating is caused;

[0012] B, under the action of the user, the external air entering from the far-lip end of the cigarette makes the temperature of the smoking particles near the far-lip end of the cigarette decrease, which affects the smoking effect of the smoking particles;

[0013] C, the cigarette is relatively long and occupies a large space due to the hollow supporting segment, the cooling segment and the filter segment, which is not convenient to carry.

[0014] In order to solve the above problems, the present application is proposed. SUMMARY

[0015] The first aspect of the present application provides a smoking segment, the smoking segment 1 comprising an empty tube 1-3, the empty tube 1-3 being provided with a heat uniformizing piece 1-1 in the far-lip end, and the heat uniformizing piece 1-1 being provided with a smoking substance 1-2 downstream.

[0016] Preferably, the heat uniformizing piece 1-1 is a columnar structure with an air cavity 1-1-1, and the heat uniformizing piece 1-1 has a radial partition plate 1-1-2 inside, and the partition plate 1-1-2 is provided with a ventilation hole.

[0017] Preferably, the partition plate 1-1-2 is located in the middle of the heat uniformizing piece 1-1, so as to form an air cavity 1-1-1 upstream and downstream of the partition plate 1-1-2. When the smoking substance 1-2 is filled into the heat uniformizing piece 1-1, the air cavity 1-1-1 downstream of the partition plate 1-1-2 is filled with the smoking substance 1-2.

[0018] The provision of the ventilation hole on the partition 1-1-2 should be understood as that the partition 1-1-2 is permeable at least when the smoking segment 1 is being smoked. The partition 1-1-2 can have the ventilation hole or not have the ventilation hole when the smoking segment 1 is not in use. For example, the partition 1-1-2 does not have the ventilation hole when the smoking segment 1 is not in use. When the smoking segment 1 is being smoked, the partition 1-1-2 is pierced by the heating element to have the ventilation hole.

[0019] Preferably, the smoking substance 1-2 is selected from one or more of the following: granular smoking substance, filamentous smoking substance, massive smoking substance, flaky smoking substance; or the smoking substance 1-2 is a preformed smoking body.

[0020] The size of the ventilation hole on the partition 1-1-2 is smaller than the size of the granular smoking substance, so as to prevent the granular smoking substance from leaking out.

[0021] More preferably, the smoking substance 1-2 is one or more of the following: filamentous smoking substance, massive smoking substance, flaky smoking substance, or preformed smoking body.

[0022] When the smoking substance 1-2 uses the filamentous smoking substance, the massive smoking substance, the flaky smoking substance, or the preformed smoking body, the proximal lip end of the hollow tube 1-3 can be open. Because the filamentous smoking substance, the massive smoking substance, or the flaky smoking substance can be tightly packed by itself and pressed without falling out of the proximal lip end. The preformed smoking body itself has integrity and can also be achieved without falling out of the proximal lip end.

[0023] Preferably, the uniform heating element 1-1 contains ferromagnetic material or does not contain ferromagnetic material.

[0024] Preferably, the material of the uniform heating element 1-1 is selected from one or more of the following: ceramic, metal, graphite, wood, polymer.

[0025] For example, the inner layer of the uniform heating element 1-1 is a metal layer, and the outer layer is a paper layer. Alternatively, the material of the uniform heating element 1-1 is selected from the following polymers: starch, cellulose, polycarbonate, polyether ether ketone, Teflon, etc.

[0026] More preferably, the uniform heating element 1-1 contains ferromagnetic material, so as to heat by electromagnetic induction when used with an electromagnetic heating type smoking set. For example, the inner wall of the uniform heating element 1-1 contains ferromagnetic material. Specifically, one or more inner walls of the uniform heating element 1-1 are coated with ferromagnetic material. Alternatively, the material of the uniform heating element 1-1 directly uses iron.

[0027] Preferably, the smoking substance 1-2 comprises granular smoking substance, and a hole-blocking member 1-4 is arranged downstream of the smoking substance 1-2. The size of the holes in the hole-blocking member 1-4 is smaller than the size of the granular smoking substance, so as to prevent the granular smoking substance from leaking out.

[0028] Preferably, the distal lip end of the hollow tube 1-3 is provided with a sealing member 1-5.

[0029] When the smoking segment 1 is not in use, the sealing member 1-5 can prevent water vapor from entering the smoking segment 1, thereby preventing the smoking segment 1 from being damp. When the smoking segment 1 is in use, the sealing member 1-5 needs to be torn off or pierced, so as to allow external air to enter the smoking segment 1.

[0030] Of course, the sealing member 1-5 can be provided with a heating element insertion hole, in which case the sealing member 1-5 does not need to be torn off or pierced.

[0031] Preferably, the sealing member 1-5 is a pierceable sealing member or is provided with a heating element insertion hole.

[0032] The sealing member 1-5 can be made of one or a combination of paper, metal, and polymer.

[0033] Preferably, the axial cross-section of the heat-uniformizing member 1-1 is a side-up H shape.

[0034] Preferably, the hollow tube 1-3 is made of one or a combination of paper, metal, and polymer. For example, the inner layer of the hollow tube 1-3 can be a metal layer, and the outer layer can be a paper layer.

[0035] Preferably, the hollow tube 1-3 is designed in an integrated or split manner. That is, the hollow tube 1-3 can be formed by detachably connecting two or more hollow tubes.

[0036] Preferably, the inner wall of the hollow tube 1-3 is provided with a metal foil layer. The metal foil layer can quickly absorb and conduct heat, thereby increasing the uniformity of heat conduction and heat transfer of air flow in the entire space of the smoking segment 1. When the metal is a ferromagnetic metal, the metal foil layer can also be subjected to electromagnetic heating under the action of an external alternating magnetic field.

[0037] The second aspect of the present application provides a manufacturing method of the smoking segment according to any one of the first aspect. The manufacturing method is a rolling method, which comprises the following steps:

[0038] Combining the smoking substance 1-2 with the heat-uniformizing member 1-1 and wrapping them with a wrapping member to form the smoking segment 1.

[0039] The wrapping member forms the hollow tube 1-3.

[0040] The third aspect of the present application provides a method for manufacturing the smoking segment according to any one of the first aspect, wherein the method is a forward order filling method or a reverse order filling method.

[0041] The forward order filling method comprises the following steps:

[0042] The forward order filling method comprises the following steps:

[0043] The reverse order filling method comprises the following steps:

[0044] The reverse order filling method comprises the following steps:

[0045] The way of fixing the sealing member 1-5 at the distal end of the hollow tube 1-3 can be extrusion or adhesion.

[0046] The heat uniformizing member 1-1 is fixed in the hollow tube 1-3 by the side wall. For example, the heat uniformizing member 1-1 is fixed by the interaction, such as extrusion or adhesion, between the side wall of the heat uniformizing member 1-1 and the side wall of the hollow tube 1-3. The distal end of the hollow tube 1-3 is sealed by the heat uniformizing member 1-1 for the particulate smoking substance. This structure greatly simplifies the manufacturing process of the particulate smoking segment.

[0047] The fourth aspect of the present application provides the use of the smoking segment according to any one of the first aspect in a heat-type cigarette, wherein the smoking segment 1 is used in combination with a hollow cavity segment and / or a filter segment for a heat-type cigarette.

[0048] The fifth aspect of the present application provides the use of the smoking segment according to any one of the first aspect in a heat-type smoking device, wherein the smoking segment 1 is used in a heat-type smoking device containing a hollow cavity segment and / or a filter segment.

[0049] The heating method of the heat-type smoking device can be using a peripheral heating tube, using an inserted central heating element, or electromagnetic heating.

[0050] The hollow cavity segment is used to cool the smoke generated by the smoking segment 1 and form an aerosol. The filter segment is used to filter impurities in the smoke.

[0051] In this document, "upstream" to "downstream" are relative terms. When a heat-type cigarette or a smoking segment is smoked, the direction of the smoke flow in the heat-type cigarette or the smoking segment is recorded as from "upstream" to "downstream".

[0052] In the present document, the terms "proximal end", "distal end" are relative terms, which refer to two ends of a smoking article or a segment of the smoking article. The "proximal end" refers to the end of the smoking article or the segment of the smoking article which is closer to the user's lips when the smoking article is used. The "distal end" refers to the end of the smoking article or the segment of the smoking article which is farther away from the user's lips when the smoking article is used.

[0053] Correspondingly, if the smoking article or the segment of the smoking article is segmented, the segment containing the proximal end is referred to as the "proximal segment" herein, and the segment containing the distal end is referred to as the "distal segment" herein.

[0054] That is, the smoking article has "proximal end", "distal end", "proximal segment" and "distal segment". Correspondingly, a segment of the smoking article also has "proximal end", "distal end", "proximal segment" and "distal segment".

[0055] The smoking article can be a heat-not-burn cigarette or a smoking segment.

[0056] Compared with the prior art, the smoking segment of the present application has the following beneficial effects:

[0057] 1. The present application creatively designs a smoking segment. The distal segment of the smoking segment 1 is provided with a uniform heating element 1-1 having a baffle 1-1-2. After the smoking segment 1 is heated, the air (including the original air and the subsequent air) in the air cavity 1-1-1 upstream of the baffle 1-1-2 is heated into hot air, which enters the smoking material through the air holes on the baffle 1-1-2 of the uniform heating element 1-1 for airflow heating. The introduction of airflow heating greatly improves the uniformity of the heating of the smoking material, so that the distal end of the smoking material can also be in contact with the high-temperature hot air and be fully heated to generate smoke.

[0058] 2. The smoking segment 1 of the present application can be used alone, and the cooling segment and / or the filtering segment in the smoking set can be used to complete the cooling and / or filtering functions. Compared with the heat-not-burn cigarette, the product form of the smoking segment is more compact in structure.

[0059] 3. The uniform heating element 1-1 of the present application can also be easily put into the smoking segment 1. The uniform heating element 1-1 is rolled together with the smoking material 1-2 by the cigarette paper to form the smoking segment 1. Alternatively, the uniform heating element 1-1 is directly filled into the hollow tube 1-3 through a filling process.

[0060] 4. In the preferred technical solution, the uniform heating element 1-1 contains ferromagnetic material, and the electromagnetic heating method can be directly used to heat the smoking segment 1. At this time, it is not necessary to use the plug-in type central heating element, thereby avoiding the problem of ectopic of the smoking material after the heating element is inserted.

[0061] 5. The smoking segment 1 of the present application is a three-purpose type, and its heating methods include the following three kinds:

[0062] Method one, circumferential heating + end air flow heating:

[0063] The smoking section 1 of the present application can be heated by a circumferential heating tube. The heating tube can directly heat the shell of the smoking section 1, conduct heat to the smoking material 1-2 through the shell of the smoking section 1, and heat the air (including the original air and the subsequent entering air) in the air uniforming member 1-1, so that the hot air air flow heats the smoking material 1-2.

[0064] Method two, central heating + end air flow heating:

[0065] The smoking section 1 of the present application is heated by a central heating element. The heating element is inserted into the air uniforming member 1-1, and further, the heating element can also extend into the smoking material 1-2. The central heating element heats the air (including the original air and the subsequent entering air) in the air uniforming member 1-1, so that the hot air air flow heats the smoking material 1-2, and the central heating element can also directly conduct heat to the smoking material 1-2.

[0066] Method three, end air flow heating:

[0067] The air uniforming member 1-1 is a ferromagnetic heating element, which is used with an electromagnetic heating type smoking set. After the air uniforming member 1-1 is heated, it heats the air (including the original air and the subsequent entering air) in it, so that the hot air air flow heats the smoking material 1-2.

[0068] 5. If the air uniforming member 1-1 is a cup-shaped structure standing on the side, when the smoking section 1 is made by a rolling process or a filling process, attention must be paid to the orientation of the air uniforming member 1-1, and the cup bottom end of the air uniforming member 1-1 should be close to the smoking material. However, an identification device for identifying the orientation of the air uniforming member 1-1 must be added, which greatly increases the cost and the complexity of the manufacturing process.

[0069] The present application creatively sets a radial partition plate 1-1-2 in the middle of the air uniforming member 1-1, and the axial cross section of the air uniforming member 1-1 is similar to an H type. In this way, the orientation of the air uniforming member 1-1 does not matter when the two ends of the air uniforming member 1-1 face the smoking section 1. Therefore, the identification device for identifying the orientation of the air uniforming member 1-1 is avoided, which greatly reduces the cost and simplifies the manufacturing process.

[0070] 6. When the smoking material 1-2 is a granular smoking material, the two ends of the smoking section 1 are respectively sealed by the air uniforming member 1-1 and the blocking member 1-4 to seal the granular smoking material. The air uniforming member 1-1 has the functions of sealing the granular smoking material and air flow heating.

[0071] In addition, from the manufacturing process of the granular smokable segment, the bottom hole-equipped heat uniformizing member 1-1 is also very easy to be filled into the empty tube 1-3: the heat uniformizing member 1-1 can be directly inserted into the empty tube 1-3 from the distal lip end or the proximal lip end. Therefore, the smokable segment 1 of the present application is very suitable for the filling process of the conventional granular cigarette. BRIEF DESCRIPTION OF DRAWINGS
