The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limiting the utility model.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] In the related art, heat-not-burn cigarettes can be made into central heating type and circumferential heating type. Among them, the circumferential heating type has a large heating area, a high degree of heating of the tobacco matrix, and good smoke quality. However, since the circumferential heating device is an enclosed and sealed heating design, during the heating and smoking process, the smoke components released by heat may migrate to the lower temperature area inside the tobacco core material, causing some smoke components to stay in the tobacco matrix for a long time. After a long period of heating and roasting, the smoke components may produce odor, which in turn leads to a poor user experience.

[0023] In order to solve the above problems in the related art, this embodiment provides a cigarette structure and a heating system.

[0024] like Figure 1-3 As shown, in this embodiment, the cigarette structure includes: an outer shell 1 and a ventilation piece 2 fixed in the outer shell 1, the outer side of the ventilation piece 2 and the inner wall of the outer shell 1 enclose a receiving cavity 1a for filling a smoke-generating body (tobacco raw material, not shown in the figure); an airflow channel 2a connected to the atmosphere is formed in the ventilation piece 2, and the ventilation piece 2 includes a transition surface 212 with a through hole, and the through hole (not shown in the figure) connects the receiving cavity 1a and the airflow channel 2a; when working, the airflow passes through the through hole from the receiving cavity 1a and enters the airflow channel 2a.

[0025] Specifically, the cigarette is arranged to be a hollow structure so that an airflow channel 2a is formed in the cigarette structure, and a transition surface 212 is arranged between the airflow channel 2a and the receiving chamber 1a. The transition surface 212 is not parallel to the airflow direction in the corresponding area of ​​the airflow channel 2a. The existence of the transition surface 212 can not only allow the aerosol generated by the smoke-generating body to be transmitted to the airflow channel 2a through the through holes thereon, and then enable the aerosol to merge with the atmosphere in the airflow channel 2a, but also ensure that the smoke-generating body material in the receiving chamber 1a is not easy to migrate into the airflow channel 2a under the impetus of the airflow during the inhalation process, thereby ensuring the excellent taste of the smoke and improving the user experience.

[0026] In this embodiment, the ventilation member 2 includes a ventilation tube 21 forming an airflow channel 2a and a filter rod 22 fixed in the ventilation tube 21. The transition surface 212 is a part of the ventilation tube 21. The smoke-generating body and the filter rod 22 are respectively located at the two ends of the transition surface 212 in the axial direction of the shell 1, so that when the cigarette structure is working, the airflow first passes through the transition surface 212 and then reaches the filter rod 22. Specifically, the filter rod 22 is arranged in the airflow channel 2a. After the smoke-generating body is heated, the generated aerosol (the component released by the smoke-generating body when heated) can flow to the airflow channel 2a along the through hole of the transition surface 212. After the aerosol enters the airflow channel 2a, it mixes with the air flow in the airflow channel 2a to achieve cooling and flows to the filter rod 22, and then is filtered by the filter rod 22 and finally transmitted to the outside for user experience. The filter rod 22 in this embodiment can filter out particulate impurities in the smoke airflow, further improve the quality of the smoke, and ensure the user's smoking experience.

[0027] In this embodiment, the ventilation pipe 21 also includes an air pipe 211 and a cooling pipe 213, and the transition surface 212 is connected between the air pipe 211 and the cooling pipe 213. The cross-sectional area of ​​the air pipe 211 is smaller than the cross-sectional area of ​​the cooling pipe 213; the filter rod 22 is fixed in the cooling pipe 213, and the receiving chamber 1a is formed on the outer peripheral side of the air pipe 211. Specifically, the air pipe 211 can be an empty pipe, and the receiving chamber 1a is formed on the outer peripheral side of the air pipe 211. The existence of the air pipe 211 can prevent the components released by the heated tobacco raw materials on the outside of the smoke body from migrating to the unheated area in the smoke body, ensuring that more components are carried into the smoke with the air flow to avoid the generation of odor. The cooling pipe 213 has a large diameter, and the components released by the smoke body material can reach the cooling pipe 213 after passing through the transition surface 212, and achieve a certain degree of cooling to meet the user's suction temperature requirements.

[0028] In this embodiment, the shape of the air passage 211 is one of a straight cylinder, a curve, a step, and a spiral. In a preferred implementation of this embodiment, the air passage 211 can be configured as follows: Figure 1 and 2The straight cylindrical structure shown is simple in structure and has a large space in the receiving cavity 1a formed by the housing 1. In another preferred embodiment of this embodiment, the air passage 211 can be configured as follows: Figure 3 The stepped structure shown in the figure, the air tube 211 of this structure can cut off the transmission of the components released by the heat of the smoke body along the radial direction of the cigarette during the heating process of the cigarette, so that these components can move more along the axial direction of the cigarette, migrate to the airflow channel 2a and flow out of the device together with the suction airflow for user experience. It should be noted that in some embodiments, the shape of the air tube 211 can also be a combination of the above-mentioned multiple shapes, and can even be an irregular shape, which is not limited here. It is understandable that in the specific implementation process, the structural size of the air tube 211 can be adjusted and set according to the filling amount of the smoke body, the sensory requirements of suction, etc., which is not limited here.

[0029] In this embodiment, the air passage 211, the transition surface 212, and the cooling tube 213 are an integrated structure, which improves the overall structural stability of the air passage 21 and ensures the repeated stability of the cigarette structure. Further, in this embodiment, the air passage 21 can be a hard tube, for example, the air passage 21 can be a high-temperature resistant hard plastic tube. Since the air passage 21 has a certain hardness and the inner wall of the shell 1 fits the outer wall of the cooling tube 213, the hardness texture of the cigarette structure can be improved, and the cigarette structure can be prevented from being deformed when inserted into the assembly cavity of the heating component, and the accuracy of the insertion depth of the cigarette structure can be ensured to a certain extent, that is, the insertion depth can be accurately located to avoid energy waste.

[0030] In the present embodiment, the transition surface 212 is one of a plane, an inclined surface, and an arc surface. Preferably, the transition surface 212 of the present embodiment can be set to an arc surface. The existence of the transition surface 212 can ensure that the smoke-generating body material will not move into the ventilation pipe 21 with the driving effect of the airflow during the suction process, so that the filling position of the tobacco raw material is more stable. In the present embodiment, a plurality of through holes are arranged at intervals, and the axis of each through hole can be parallel to the axis of the cooling tube 213, so that the transmission of the smoke components is smoother. The shape of the through hole can be a combination of one or more of a circular, elliptical, polygonal, and irregular shape, which is not limited here. In the specific implementation process, the number, size, and shape of the through hole can be determined according to factors such as the cooling and interception requirements of the filter rod 22, which is not limited here.

[0031] In this embodiment, the shape of the smoke body is at least one of filament, sheet, and granule, that is, the receiving cavity 1a in this embodiment can be filled with a single or mixed tobacco raw material in various forms such as shredded tobacco, thin sheets, and granules, which can be selected according to the actual needs of the user and are not limited here. In this embodiment, the shell 1 can be a paper shell, and the material of the shell 1 can be cigarette paper or tipping paper, etc., which is low in cost and easy to obtain.

[0032] In this embodiment, the heating system includes a heating component and a cigarette structure, and the heating component is used to heat the cigarette structure. Specifically, the heating component can be configured to allow the cigarette structure to be inserted into a fixed assembly cavity, and the heating component can heat the smoke-generating body in the cigarette structure after being powered on, so as to generate aerosol; the heating area of ​​the heating component coincides with the position of the receiving cavity 1a, ensuring sufficient heating area and avoiding energy waste.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
