[0043] This invention provides a heated cigarette, comprising a smoke-generating section with a built-in heating element and a filter section; the filter section is connected to the smoke-generating section; the heating element is placed inside the smoke-generating section, and the heating element generates heat to heat the tobacco substances in the smoke-generating section. The heated cigarette has the heating element in the smoke-generating section, which generates heat to heat the tobacco substances in the smoke-generating section. Therefore, in use, the heated cigarette no longer needs to be used with a separate heating device; it can be directly heated and smoked by its own heating element, improving the convenience of smoking and eliminating the need for cleaning the heating device, thus enhancing the smoker's experience.

[0044] Please refer to the following: Figures 1 to 3 This embodiment provides a heated cigarette 100, specifically a heated cigarette 100 with a built-in heating element. It can generate heat through its built-in heating element, so that it does not require an additional heating device when smoking, thus improving the convenience of smoking.

[0045] The heated cigarette 100 includes at least a smoke-generating section 10 with a built-in heating element 30 and a filter section 20, wherein the filter section 20 is connected to the smoke-generating section 10. The connection between the filter section 20 and the smoke-generating section 10 can be direct or indirect; for example, the filter section 20 can be directly connected to one end of the smoke-generating section 10. Alternatively, the heated cigarette 100 may also include other components. The heated cigarette 100 may be composed of the smoke-generating section 10 with a built-in heating element 30, the filter section 20, and other components, which may be disposed between the smoke-generating section 10 and the filter section 20. The smoke-generating section 10 is used to generate aerosol gas, and the filter section 20 is used to maintain, adsorb, and filter the aerosol gas generated by the smoke-generating section 10, so that the aerosol gas generated by the smoke-generating section 10 meets the absorption requirements.

[0046] The heating element 30 is built into the smoke-generating section 10 and is used to generate heat to heat the tobacco material 11. In other words, the smoke-generating section 10 is equipped with the heating element 30, which generates heat through its own heating. When a smoker needs to inhale the heated cigarette 100, the heat generated by the heating element 30 heats the tobacco material 11, enabling heated inhalation. The tobacco material 11 can be a granular smoke-generating material or a sheet-type smoke-generating material. The preparation method for sheet-type smoke-generating materials can be a slurry method, a papermaking method, a dry papermaking method, or a rolling method, etc. Furthermore, the tobacco material 11 can be any other material that can generate aerosols.

[0047] Understandably, existing heated cigarette technology requires a heating device for smoking, forcing smokers to carry the device with them, significantly reducing convenience compared to traditional cigarettes. Furthermore, after smoking, tobacco residue often remains inside the heating device, requiring cleaning and further compromising convenience and the smoker's experience.

[0048] The heated cigarette 100 provided in this embodiment directly incorporates the heating element 30 within the smoke-generating section 10, eliminating the need for heating devices during smoking and improving convenience. Furthermore, the heating device is not required to be cleaned after smoking, further enhancing convenience and the smoker's experience.

[0049] Preferably, in one embodiment, the heating element 30 extends axially along the smoke-generating section 10. This structure allows the heating element 30 to better and more fully heat the tobacco material 11 in the smoke-generating section 10.

[0050] Preferably, the heating element 30 and the smoke-generating section 10 are arranged in direct contact. That is, no other components are provided between the heating element 30 and the smoke-generating section 10 to block them, and the heating element 30 is in direct contact with the smoke-generating section 10, so that the heating element 30 can provide heat to heat the smoke-generating section 10 more effectively.

[0051] Preferably, in one embodiment, the central axis of the heating element 30 and the central axis of the smoke-generating section 10 are located on the same plane. That is, the heating element 30 is disposed at the exact center of the smoke-generating section 10, so that the heating element 30 can heat the tobacco material 11 in all parts of the smoke-generating section 10 more evenly, thereby improving the smoking experience.

[0052] Preferably, in one embodiment, the heating element 30 is located at the end away from the filter section 20. More preferably, the end of the heating element 30 away from the filter section 20 is flush with the end of the smoke-generating section 10 away from the filter section 20. This structure better ensures the overall flatness of the heated cigarette 100, better ensures the aesthetics of the heated cigarette 100, and also makes it less likely for the tobacco material 11 in the smoke-generating section 10 to scatter.

[0053] Preferably, in one embodiment, the heating element 30 includes a ventilation pipe 31, a heating tube 32, a heating agent 33, and a sealing assembly 34. The ventilation pipe 31 extends axially along the smoke-generating section 10, and an air cavity 311 is provided inside the ventilation pipe 31. The heating tube 32 extends axially along the smoke-generating section 10, and the heating tube 32 is located around the ventilation pipe 31. The heating agent 33 fills the heating tube 32, and the heating agent 33 is located between the heating tube 32 and the ventilation pipe 31. The heating agent 33 is used to generate heat by contacting air. The sealing assembly 34 is disposed at the end of the ventilation pipe 31 and the heating tube 32 away from the filter section 20, and the sealing assembly 34 is used to block air. That is, in one embodiment, the heating element 30 generates heat by producing a chemical reaction with air, thereby heating the tobacco material 11. When the heated cigarette 100 is not in use, the sealing assembly 34 isolates the air, preventing the heating agent 33 from generating heat. When the heated cigarette 100 needs to be smoked, the components in the sealing assembly 34 are removed, allowing air to enter the heating element 30 and react with the heating agent 33 to generate heat. This structure further simplifies the smoking process, improving convenience and the smoker's experience.

[0054] Preferably, in one embodiment, the central axis of the ventilation pipe 31, the central axis of the heating pipe 32, and the central axis of the heating element 30 are located on the same plane, that is, the ventilation pipe 31 and the heating pipe 32 are located at the exact center of the heating element 30, so that the heating element 30 can heat up more evenly and heat the tobacco material 11 in the smoke-generating section 10 more evenly, thereby further improving the smoking experience.

[0055] Preferably, in one embodiment, the air cavity 311 is filled with a filler 35, which helps to better maintain the overall structure of the heating element 30 and better ensures the stability of the heating element 30 during use. More preferably, the filler 35 is a fiber filler, which is non-toxic, harmless, and inexpensive.

[0056] Preferably, in one embodiment, the vent pipe 31 has a through hole that connects the air cavity 311 to the area where the heating agent 33 is located. Thus, when the heated cigarette 100 is in use, air can flow through the air cavity 311 into the area where the heating agent 33 is located, achieving a contact reaction between the air and the heating agent 33.

[0057] Preferably, in one embodiment, the heating agent 33 comprises at least activated carbon, iron powder, and zeolite powder. That is, in one embodiment, the heating agent 33 may be composed of activated carbon, iron powder, zeolite powder, etc. Of course, in other embodiments, the specific formulation of the heating agent 33 can be selected according to the actual required heating temperature.

[0058] Preferably, in one embodiment, multiple through holes are provided, and all through holes are evenly distributed on the vent pipe 31. This structure can better ensure that the heating agent 33 has uniform contact with the air at all points, and ensure that the heating element 30 heats up evenly at all points.

[0059] Preferably, in one embodiment, the sealing assembly 34 includes a sleeve cap 341 and sealing tape 342. The sleeve cap 341 covers the end of the vent pipe 31 and the heating pipe 32 away from the filter section 20, and the sleeve cap 341 has a vent 3411 corresponding to the air cavity 311. The sealing tape 342 is pasted to the end of the sleeve cap 341 away from the filter section 20 to seal the vent 3411, and the end face of the sealing tape 342 is flush with the end face of the smoke-generating section 10. This structure makes it more convenient to smoke the heated cigarette 100. The smoker only needs to tear off the sealing tape 342 to allow air to enter the air cavity 311 through the vent 3411, which can realize the heating of the heating element 30, and can further improve the smoker's smoking experience.

[0060] Preferably, in one embodiment, the heating tube 32 has a heat transfer temperature of 200-400 degrees Celsius. That is, the heating tube 32 can be made of any material with a heat transfer temperature of 200-400 degrees Celsius, thereby enabling better heating of the smoke-generating section 10. In this embodiment, specifically, the heating tube 32 is a tin foil tube, which better ensures the stability of heat transfer by the heating tube 32.

[0061] The lengths of each component segment of the heated cigarette 100 can be adjusted according to the requirements of the composite equipment. Specifically, in one embodiment, the diameter of the smoke-generating segment 10 is 7.16 mm, and the length of the smoke-generating segment 10 is 51 mm. The diameter of the heating element 30 is 3.1 mm, and the length of the heating element 30 is 48 mm. This minimizes the space occupied by the heating element 30 in the smoke-generating segment 10, ensuring the volume of the tobacco material 11 in the smoke-generating segment 10, while also better ensuring the heating effect of the heating element 30 on the tobacco material 11.

[0062] Preferably, in one embodiment, the filter section 20 is a multi-component composite filter section. That is, the filter section 20 has a multi-component composite structure, such as a conventional three-section composite or other composite form. For example, in one embodiment, the filter section 20 includes a cooling section 21, a hollow filter rod section 22, and a cellulose acetate section 23 connected in sequence, with the cooling section 21 connected to the smoke-generating section 10. This structure allows the filter section 20 to better filter and cool the smoke, thus improving the smoker's inhalation experience.

[0063] Specifically, in one embodiment, the length of the cooling section 21 is 16mm, the length of the hollow filter rod section 22 is 10mm, and the length of the cellulose acetate section 23 is 7mm, which further ensures the filtration and cooling effect of the filter section 20.

[0064] This embodiment also provides a method for smoking heated cigarettes, which includes the following steps:

[0065] S1. Provide the heated cigarette 100;

[0066] S2. The tobacco substance 11 in the smoke-generating section 10 is heated by the heating element 30.

[0067] Preferably, in one embodiment, step S2 specifically includes the following steps:

[0068] S21. Remove the sealing tape 342 from the heating element 30;

[0069] S22. Remove the filler 35 from the heating element 30 and allow air to enter the heating element 30 to react with the heating agent 33 to generate heat.

[0070] Specifically, the filler 35 in the heating element 30 is removed, allowing air to enter the air cavity 311, and then enter the area where the heating agent 33 is located through the through hole to react with the heating agent 33 and generate heat.

[0071] S23. The heat generated by the heating agent 33 is transferred through the heating tube 32 to the tobacco material 11 in the smoke-generating section 10, thereby heating and generating smoke. The heated cigarette 100 thus produces smoke for the smoker to inhale. The heating temperature is generally around 350°C, and the temperature range can be adjusted by changing the formula of the heating agent 33.

[0072] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
