Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heated cigarettes, in particular to a heated cigarette and a heated smoking set. BACKGROUND

[0002] Heated cigarettes, also known as low-temperature cigarettes, mainly use a heated smoking set to heat and evaporate smoking materials to generate aerosol for consumers to smoke, which can achieve a similar satisfaction to cigarettes and reduce the generation of harmful substances.

[0003] In order to smoothly flow air and aerosol, an airflow channel needs to be formed inside the heated cigarette, and the ends of the cigarette are usually open. However, the current mainstream smoking material forms include granular, cut tobacco, and reconstituted tobacco, which are relatively small in volume and easy to fall off from the open port, affecting the consumer experience.

[0004] To solve the problem of tobacco falling off, some products on the market add a sealing structure to the smoking segment or directly seal it. However, the sealing structure will cause changes in the structure of the cigarette, and the corresponding preparation, splicing, and other processes need to be adjusted, greatly increasing the cost. In addition, the direct sealing method will affect the airflow circulation and the intake of air, or cause uneven heating before and after, which will also adversely affect the smoking experience. UTILITY MODEL CONTENT

[0005] To solve the above technical problems, the first purpose of the present application is to provide a heated cigarette, and the second purpose of the present application is to provide a heated smoking set which is used in conjunction with the above-mentioned heated cigarette. The heated cigarette provided by the present application can reduce or avoid the falling off of the smoking materials in the smoking segment. The sealing member is pierced by the matching heated smoking set during smoking to form an air flow channel, the suction resistance is appropriate, and the smoking experience is guaranteed.

[0029] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application.

[0032] In addition, the terms "first", "second", etc. are used only for descriptive purposes and should not be construed as implying or creating a relative importance or an implied indication of the number of technical features indicated. Thus, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features.

[0033] It should be understood that the structures, proportions, sizes, etc. shown in the drawings of the present application are only used to cooperate with the disclosed content, to be understood and read by those skilled in the art, and do not have technical significance. Any modification of structure, change of proportion relationship or adjustment of size, which does not affect the effect and purpose that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application.

[0034] As shown in the figure, the heating cigarette provided by the embodiment of the present application comprises a smoke generating segment 1 and a filter segment 2 connected together, and the free end of the smoke generating segment 1 is completely closed or partially closed by a sealing member 3.

[0035] The end of the smoke generating segment 1 connected with the filter segment 2 is directly contacted by the smoke generating material contained in the smoke generating segment 1 and the filter material contained in the filter segment 2.

[0036] In view of the problems existing in the prior art, the present application first provides a heating cigarette comprising a smoke generating segment 1 and a filter segment 2 connected together, i.e. the smoke generating segment 1 is at one end of the heating cigarette, and the filter segment 2 is at the other end. The free end of the smoke generating segment 1 (i.e. the end away from the filter segment 2) is completely closed or partially closed by a sealing member 3. The end of the smoke generating segment 1 connected with the filter segment 2 is not closed, and the smoke generating material contained in the smoke generating segment 1 is directly contacted with the filter material contained in the filter segment 2.

[0037] The heating cigarette provided by the present application has the free end of the smoke generating segment 1 completely closed or partially closed, so as to reduce or avoid the smoke generating material contained in the smoke generating segment 1 from falling off. At the same time, the end of the smoke generating segment 1 connected with the filter segment 2 is directly contacted by the smoke generating material and the filter material without a sealing member arranged therebetween, so that the airflow can freely pass between the smoke generating material and the filter material, thereby avoiding the problem of large resistance and complex airflow passage caused by the closed part. When the heating cigarette provided by the present application is smoked, the sealing member 3 is pierced by a matching heating smoking set to form an air flow channel, so that the air can smoothly enter the inside from the end face of the free end of the smoke generating segment 1. Then the formed aerosol can directly enter the filter segment 2 from the other end of the smoke generating segment 1 which is not closed, and is filtered by the filter material before being smoked by the consumer, so that the resistance is appropriate and the smoking experience is guaranteed.

[0038] The smoking material of the smoking segment 1 has no special requirements, and materials of common types such as granular, tobacco shred, and reconstituted tobacco can be used. At the end provided with the sealing member 3, the whole end can be closed to ensure that the smoking material does not fall off; or the end can be partially closed, and the proportion of the size of the aperture of the partially closed area to the size of the smoking material can be controlled to ensure that the smoking material does not fall off under normal storage and use of the heated cigarette by means of the wrapping effect of the partially closed area and the friction between the smoking materials. At the end where the smoking segment 1 is connected to the filter segment 2, no additional sealing structure is provided, and the position of the smoking material is maintained by the contact between the filter material and the smoking material. At the same time, the gaps between the smoking materials and the gaps between the filter materials can allow air to flow freely, avoiding excessive suction resistance and ensuring that the air intake is within an appropriate range. In addition, the problem of uneven heating before and after heating caused by local overheating can be avoided.

[0039] The filter segment 2 can include multiple filter segments of different forms, such as filter segments with cavities in the middle and filter segments filled with acetate tow.

[0040] Preferably, the aperture formed by the partial closure is located at the center of the end face of the smoking segment 1.

[0041] When the free end of the smoking segment 1 is partially closed by the sealing member 3, the aperture formed (i.e., the unsealed part) can be located at any position of the cross section of the smoking segment 1, as long as there is a sealed part and an unsealed part on the end face of the smoking segment 1, which is a case of partial closure. More preferably, the aperture formed by the partial closure is located at the center of the end face of the smoking segment 1, which facilitates the corresponding heating device to provide a structure to damage the sealing member 3. As long as the aperture is offset from the structure for damaging the sealing member 3, the sealing member 3 can be damaged, and the effect of damaging the sealing member 3 will not be affected by the different angles at which the consumer inserts the cigarette.

[0042] Preferably, the sealing member 3 is formed by folding the part of the wrapping material of the heated cigarette that is longer than the smoking segment 1; or,

[0043] The sealing member 3 is a sealing sheet, and the sealing sheet is connected to the smoking segment 1 by adhesive bonding.

[0044] The formation of the sealing member 3 preferably adopts the following two methods:

[0045] The first way is to fold the part of the heating cigarette wrapping material longer than the heating segment 1 to form the sealing member 3. That is, the heating cigarette wrapping material is set to a length longer than the heating segment 1 in advance, and the part of the wrapping material longer than the heating segment 1 is folded to the end face of the heating segment 1 after wrapping to form the sealing member 3. The folding method can be achieved by a method known in the art, for example, wrapping the wrapping material at an angle. By controlling the length of the excess wrapping material, a fully closed sealing member 3 can be formed, or a partially closed sealing member can be formed. By cutting the wrapping material, the hole in the partially closed sealing member can be located at different positions on the end face of the heating segment 1. However, for the sake of easy operation, it is preferred that the hole is naturally left at the center of the end face when partially closed.

[0046] The second way is to use a pre-prepared sealing sheet to be connected to the heating segment 1 by adhesive. The sealing sheet can be perforated to achieve partial closure, or it can be a whole piece of material to achieve full closure.

[0047] The use of wrapping material folding or adhesive sealing sheet method has simple structure and is easy to implement, and changes little to the existing equipment and process, which can avoid the problem of huge cost caused by the addition of sealing structure to the heating segment 1 and the resulting large changes in process and equipment.

[0048] Preferably, the material of the sealing member 3 is paper; and / or,

[0049] The sealing sheet is connected to the heating segment 1 by plant glue.

[0050] Preferably, the material of the sealing member 3 is any one of cigarette paper, cellulose paper, or aluminum foil paper;

[0051] The plant glue is any one or more of starch glue, dextrin glue, guar gum, gum arabic, and lignin glue.

[0052] Preferably, the material of the sealing member 3 is paper, and more preferably, the material of the sealing member 3 is any one of cigarette paper, cellulose paper (such as oil and moisture resistant paper), or aluminum foil paper, which will not adversely affect the smoking experience and is easy to obtain and process. In particular, when the sealing member 3 is formed by folding the part of the heating cigarette wrapping material longer than the heating segment 1, directly using the wrapping material only changes its length, and the production raw materials and process do not need to be greatly changed, which can reduce the cost.

[0053] When using a sealing sheet, it is preferred to be connected by plant glue, which is environmentally friendly and safe. The plant glue is any one or more of starch glue, dextrin glue, guar gum, gum arabic, and lignin glue.

[0054] A heating device is used with any of the above heating cigarettes, and the heating device is provided with a containing cavity 4 for inserting the heating cigarette, and at least one breaking member 5 is arranged in the containing cavity 4,

[0055] The breaking member 5 is arranged on the accommodating cavity end face 41 opposite to the free end of the smoking segment 1 of the accommodating cavity 4, and is used to break the sealing member 3.

[0056] The application also provides a heating smoking set matched with the above heating cigarette, which is provided with an accommodating cavity 4 for inserting the heating cigarette, and at least one breaking member 5 is arranged in the accommodating cavity 4. The breaking member 5 is arranged on the accommodating cavity end face 41 opposite to the free end of the smoking segment 1 of the accommodating cavity 4, and is used to break the sealing member 3.

[0057] When the consumer uses the heating cigarette, the heating cigarette is inserted into the accommodating cavity 4. In this process, the breaking member 5 contacts the sealing member 3 and further inserts the sealing member 3 to break it. After the breaking, air can enter the smoking segment 1 from the broken part, so that the suction resistance of the cigarette is in a proper range, and the consumer has a good smoking experience. After the breaking member 5 breaks the sealing member 3, air can enter from the gap between the breaking member 5 and the sealing member 3, so that the air intake amount from the end of the smoking segment 1 is increased when smoking. Meanwhile, the breaking member 5 is fixed in the accommodating cavity 4 of the heating smoking set, and has simple structure, high reliability and durability, and low production cost.

[0058] The breaking member 5 is arranged on the accommodating cavity end face 41 opposite to the free end of the smoking segment 1 of the accommodating cavity 4, and only breaks the sealing member 3 on the end face of the cigarette, but does not break the wrapping material on the side of the cigarette. After smoking, the content of the cigarette is not easy to spill. Meanwhile, the broken part is located on the end face of the cigarette, and an air flow channel is better formed.

[0059] The position of the breaking member 5 can be determined according to whether the sealing member 3 completely or partially seals the end face of the smoking segment 1. When completely sealed, the breaking member 5 can achieve its function at any position on the accommodating cavity end face 41. When partially sealed, the position of the breaking member 5 is staggered with the position of the hole of the sealing member 3 which is not sealed. The staggering can be achieved by staggering the radial position of the breaking member 5 with the hole, or by respectively setting marks on the heating smoking set and the heating cigarette, and aligning the two marks to stagger the breaking member 5 with the hole of the sealing member 3.

[0060] Preferably, 2-6 breaking members 5 are arranged in the accommodating cavity 4, and the distance between at least one breaking member 5 and the center of the accommodating cavity end face 41 is greater than the distance between another breaking member 5 and the center of the accommodating cavity end face 41.

[0061] The number of the breaking members 5 is at least one, and preferably 2-6 are provided to form multiple air flow passages by breaking the sealing member 3 at multiple locations. When two or more breaking members 5 are provided, the distance of the breaking members 5 from the center of the end face 41 of the accommodating cavity is different, i.e. at least one breaking member 5 is located farther from the center of the end face 41 of the accommodating cavity than another breaking member 5. In this way, the breaking members 5 can break the sealing member 3 at different locations to facilitate air flow. At the same time, when the sealing member 3 partially seals the end face of the smoking segment 1, the breaking members 5 can break the sealing member 3 regardless of the location of the unsealed hole, and the cigarette does not need to be inserted into the heating smoking device at a specific angle, which is more convenient for consumers to operate.

[0062] Preferably, the breaking member 5 has a sharp or blade portion, and the blade portion has an axial angle with the accommodating cavity 4 greater than 0° and less than 180°.

[0063] Preferably, the breaking member 5 has a sharp or blade portion, and the sharp can pierce the sealing member 3, and the blade portion has an axial angle with the accommodating cavity 4 greater than 0° and less than 180°, or can cut the sealing member 3.

[0064] Preferably, the breaking member 5 has a tapering shape with the diameter increasing from the top end to the bottom.

[0065] Preferably, the height of the breaking member 5 is 1-5 mm.

[0066] The height of the breaking member 5 (i.e. the length of the breaking member 5 extending along the axis of the accommodating cavity 4) is 1-5 mm, and more preferably 1-2 mm. The height of the breaking member 5 is much smaller than the length of the smoking segment 1 (usually 10-12 mm), so the breaking member 5 can break the sealing member 3 without excessively extending into the smoking segment 1.

[0067] Preferably, the heating smoking device further comprises an induction heating member 6 arranged on the outer periphery of the accommodating cavity 4.

[0068] Preferably, the heating smoking device provided in the present application uses an induction heating method to heat the cigarette. Specifically, the induction heating is achieved by the induction heating member 6 arranged on the outer periphery of the accommodating cavity 4. The induction heating member 6 can use a structure known in the art, such as a spiral heating member arranged on the outer periphery of the accommodating cavity 4.

[0069] When using a resistance heating method such as a heating needle to heat, the fully sealed or partially sealed sealing member 3 of the cigarette provided in the present application can also reduce the falling of the smoking material. However, when using an induction heating method, the heating needle does not need to be inserted, which can further reduce or avoid the problem of falling of the smoking material. In addition, the induction heating does not directly contact the tobacco of the cigarette, and the heating cavity is relatively closed, which reduces the frequency of cleaning and maintenance, and also avoids the accumulation of tobacco residue and condensate caused by the insertion of the resistance heating element such as the heating needle into the tobacco component, and other bad consumer experiences.

[0070] Example 1

[0071] like Figure 1 As shown, a heated cigarette includes a smoke-generating section 1 and a filter section 2 connected together. The free end of the smoke-generating section 1 is partially closed by a sealing member 3, and the hole formed by the partial closure is located at the center of the end face of the smoke-generating section 1. At the end where the smoke-generating section 1 connects to the filter section 2, the smoke-generating material contained in the smoke-generating section 1 is in direct contact with the filter material contained in the filter section 2. The sealing member 3 is formed by folding a portion of the heated cigarette's wrapping material that is longer than the smoke-generating section 1. The sealing member 3 is made of cigarette paper.

[0072] The accompanying heating device has a cavity 4 for inserting heated cigarettes. Two puncturing elements 5 are located within the cavity 4, on the end face 41 opposite the free end of the smoking section 1, and are used to puncture the sealing element 3. The distance between one puncturing element 5 and the center of the cavity end face 41 is greater than the distance between the other puncturing element 5 and the center of the cavity end face 41. Each puncturing element 5 has a spike with a height of 2mm.

[0073] The heated smoke appliance also includes an induction heating element 6 located on the outer periphery of the accommodating cavity 4.

[0074] Example 2

[0075] like Figure 2 As shown, it is the same as in Example 1, except that the free end of the smoke-generating section 1 is completely sealed by the sealing piece 3, which is a sealing sheet made of cigarette paper and sealed with starch glue; the heating device is equipped with a sealing breaking piece 5.

[0076] Example 3

[0077] like Figure 3 As shown, it is the same as in Example 1, except that the free end of the smoke-generating section 1 is completely sealed by the sealing piece 3. The sealing piece 3 is a sealing sheet made of aluminum foil paper, which is sealed by starch glue. The heating smoke device is equipped with three sealing breaking pieces 5, and the height of the sealing breaking pieces 5 is 1.5mm.
