Description

Technical Field

[0001] The present invention relates to a cigarette heating device, in particular to a heating device used for heating cigarettes through side air intake. Background Art

[0002] Heat-not-burn cigarettes are a smoking method that heats tobacco materials through electronic devices. There is no open flame or ash produced in the process, which is environmentally friendly. Consumers can feel the aroma of tobacco when smoking cigarettes through electronic heating devices, while reducing the production of harmful substances by high-temperature pyrolysis of conventional cigarettes during combustion, providing an effective way for consumers to smoke healthily.

[0003] Currently, heat-not-burn cigarettes utilize atmospheric pressure oxygen ventilation, where external air flows longitudinally through the end face of the tobacco segment of the cigarette. During the smoking process, this longitudinal airflow causes drastic temperature fluctuations in the tobacco segment, destabilizing the tobacco pyrolysis reaction and causing oxidation reactions, leading to a reduction in smoke volume and tobacco flavor components. Therefore, improvements to cigarette heating devices are needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a heating device for side-air-inlet heating of cigarettes to address the deficiencies in the prior art. The device enables the tobacco material in the cigarette to be placed in a negative pressure and low-oxygen environment during the heating process. In this state, the mass and heat transfer of the tobacco material during the heating process is more stable. In addition, the oxidation reaction of the tobacco material is reduced in the negative pressure and low-oxygen environment, thereby increasing the types and content of flavor substances released, and improving the nicotine release and smoke volume.

[0005] The present invention provides a heating device for heating cigarettes using side air intake, which includes a device body;

[0006] The device body is cylindrical and is provided with a cigarette insertion hole, which is coaxially arranged with the device body;

[0007] The cigarette insertion hole is a blind hole; the cigarette insertion hole is used to insert a cigarette with an inlet hole on the outer surface;

[0008] An air inlet is provided on the outer periphery of the device body, and the air inlet is communicated with the blind hole.

[0009] The heating device for side air intake heating of cigarettes as described above also includes a positioning element, which is annular and installed in the cigarette insertion hole, and one end of the positioning element is fixedly connected to the bottom of the cigarette insertion hole; the positioning element is used to fix the inserted cigarette and reduce the air entering the cigarette from the end of the cigarette located in the cigarette insertion hole.

[0010] The heating device for heating cigarettes with side air intake as described above includes a heating needle, one end of which is installed at the bottom of the cigarette insertion hole, and the heating needle is coaxially arranged with the positioning element.

[0011] As described above, the heating device for side air intake heating of cigarettes has a cone head at one end of the heating needle away from the bottom of the cigarette insertion hole, and the diameter of the cone head gradually decreases in the direction away from the bottom of the cigarette insertion hole.

[0012] In the heating device for heating cigarettes with side air intake as described above, the length of the heating needle is greater than the length of the positioning element along its axis.

[0013] As described above, in the heating device for heating cigarettes with side air intake, the distance between the air intake hole and the bottom of the cigarette insertion hole is greater than the length of the heating needle.

[0014] As described above, in the heating device for heating cigarettes by side air intake, the air intake hole is used to face the intake hole on the cigarette inserted into the cigarette insertion hole.

[0015] In the heating device for heating cigarettes with side air intake as described above, the center line of the air intake hole is perpendicular to the center line of the cigarette insertion hole.

[0016] Compared with the prior art, the present invention utilizes a blind cigarette insertion hole on the device body and air inlet holes on the outer periphery of the device body. When a cigarette with an inlet hole on the outer periphery is inserted into the cigarette insertion hole, the tobacco material is placed in a negative pressure and low oxygen environment during heating. In this state, mass and heat transfer of the tobacco material during heating is more stable. In addition, the negative pressure and low oxygen environment reduces oxidation reactions of the tobacco material, thereby increasing the types and content of flavor substances released, and improving nicotine release and smoke volume.

[0024] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0025] Please refer to Figures 1 to 3 The present invention discloses a heating device for heating cigarettes with side air intake, which includes a device body 1. First, those skilled in the art will understand that the heating device is used to heat cigarettes. The parts that are the same as those in the prior art will not be repeated here. The main differences are as follows.

[0026] During specific implementation, the device body 1 is cylindrical, and the device is provided with a cigarette insertion hole 11, and the cigarette insertion hole 11 is coaxially arranged with the device body 1. The cigarette insertion hole 11 is a blind hole; the component for heating on the device body 1 is located at the bottom of the cigarette insertion hole 11. The cigarette insertion hole 11 is used to insert cigarettes with an inlet hole provided on the outer circumference. An air inlet hole 12 is provided on the outer circumference of the device body 1, and the air inlet hole 12 is connected to the blind hole. The air inlet hole 12 is used to face the inlet hole on the cigarette. Specifically, the "peripheral surface" and "periphery" referred to in the present invention refer to the circular surface, and do not include the end surface.

[0027] During use, a cigarette with an inlet hole on its outer surface is inserted into the cigarette insertion hole, and the inlet hole on the cigarette is basically aligned with the air inlet hole 12. The end of the cigarette away from the filter segment 6 is inserted into the bottom of the cigarette insertion hole 11. During heating, air enters the cigarette through the air inlet hole 12 and the inlet hole. Since only a small amount of air passes through the heating area, the temperature of the heating area is relatively stable, the oxidation reaction of the tobacco substance is reduced, and a violent oxidation reaction will not occur in the heating area. That is, the tobacco in the heating area is in a state of low oxygen during use, and the smoking action of the smoker further puts the heating component in a negative pressure state. Under the condition of negative pressure and low oxygen, the decomposition reaction of the tobacco substance can be made more stable. In addition, under the negative pressure and low oxygen state, the tobacco substance undergoes oxidation-reduction and decomposition reactions, and the types and contents of the released aroma components are increased, and the amount of nicotine and smoke is also improved.

[0028] In order to further explain the present invention clearly, the cigarette used in the present invention is now described: Please refer to Figure 3 The cigarette used in the present invention includes a cigarette body 2, which includes a tobacco material segment 3, a hollow segment 4, a cooling segment 5, and a filter segment 6 arranged in sequence. The tobacco material segment 3 is filled with tobacco. The inlet hole on the cigarette is located at the connection between the tobacco material segment 3 and the hollow segment 4.

[0029] As a preferred implementation, it further includes a positioning element 13, which is annular and mounted at the bottom of the cigarette insertion hole 11. The positioning element 13 is used to secure the inserted cigarette and reduce the amount of air that enters the cigarette from the end of the cigarette located in the cigarette insertion hole 11. The positioning element 13 cooperates with the bottom of the cigarette insertion hole 11 to block the end of the cigarette away from the filter segment 6, thereby preventing air from entering from the end of the tobacco material segment 3 away from the hollow segment 4. This allows the smoker to inhale and create a negative pressure, low-oxygen environment in the tobacco material segment 3. This ensures that the tobacco material segment maintains a relatively constant temperature during the inhalation process, and the tobacco material decomposition reaction is relatively stable.

[0030] As a preferred implementation, a heating needle 14 is further included. One end of the heating needle 14 is mounted at the bottom of the cigarette insertion hole 11 and is coaxially arranged with the positioning element 13. One end of the heating needle 14 is connected to a component for generating heat. This is prior art and is readily achievable by those skilled in the art. Details will not be given here. The provision of the heating needle 14 facilitates insertion into the tobacco material segment 3, thereby heating the tobacco within the tobacco material segment 3.

[0031] As a preferred implementation, the heating needle 14 has a tapered head 141 at one end away from the bottom of the cigarette insertion hole 11, and the diameter of the tapered head 141 gradually decreases as it moves away from the bottom of the cigarette insertion hole 11. Specifically, the provision of the tapered head 141 facilitates insertion of the heating needle 14 into the tobacco material segment 3.

[0032] As a preferred implementation, the length of the heating needle 14 is greater than the axial dimension of the positioning element 13. Specifically, the length of the positioning element 13 is less than the length of the tobacco segment of the cigarette. Furthermore, the distance between the air inlet 12 and the bottom of the cigarette insertion hole 11 is greater than the length of the heating needle 14. This prevents incoming air from passing through the heated area, thereby preventing vigorous oxidation of the tobacco segment 3 and stabilizing the pyrolysis reaction.

[0033] As a preferred implementation, the air inlet 12 is used to face the inlet hole on the cigarette inserted into the cigarette insertion hole 11. Furthermore, the center line of the air inlet 12 is perpendicular to the center line of the cigarette insertion hole 11.

[0034] To further illustrate the effects of the present invention, sensory quality evaluations were conducted on heat-not-burn cigarettes using sidestream airflow and existing products. The tobacco material segments remained unchanged, and the sidestream airflow cigarettes were used with the heating device of the present invention, with the heating curve consistent with the existing heating device. The evaluation results are shown in Table 1. As can be seen from Table 1, the sensory quality of heat-not-burn cigarettes using sidestream airflow was improved, as demonstrated by increased smoke volume and aroma, increased physiological intensity, and improved puff comfort.
