By integrating the induction heating unit into the heated tobacco product and using it in conjunction with a matching electromagnetic heating device, most of the heat from the induction heating unit built into the heated tobacco product during the puffing process is used to heat the smoke-releasing particle unit. This results in a high heat utilization rate, effectively improving the heating efficiency of the heated tobacco product, allowing the heated tobacco product to produce sufficient and uniform smoke, with less heat diffusion outward, significantly reducing the shell temperature of the electromagnetic heating device and the heat-induced impurities in the heated cigarette smoke. After the puffing is completed, the heated tobacco product can be directly pulled out of the electromagnetic heating device as a whole, without the need for an auxiliary extraction device or cleaning the device, and the appearance of the cigarette remains unchanged. In addition, the smoke-releasing particle unit is blocked at both ends by a blocking cooling unit and a blocking unit, effectively preventing tobacco particles from falling during the puffing process.

[0035] 2. The present invention provides a pellet-type heated cigarette product containing an induction heating unit. Three structural designs are available for the induction heating unit. These designs increase the contact area between the induction heating unit and the smoke-releasing particle unit, thereby increasing the heat induction area and enhancing the heating effect of the smoke-releasing particle unit. They also evenly disperse the smoke-releasing particles within the smoke-releasing particle unit, ensuring uniform heating within the unit and further promoting sufficient and uniform smoke production. Furthermore, these three structural designs are embedded within the hollow outer tube of the cigarette holder, making them easy to operate.

[0036] 3. The present invention provides a method for preparing a granular heated cigarette product containing an induction heating unit, which has a simple preparation process, high production efficiency and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] Step 7: Cigarette forming:

[0076] Cut the cigarette outer tube 1, the blocking unit 2, the blocking and cooling unit 5, and the filtering unit 3 into specified lengths, and then install the blocking unit 2, the induction heating unit 6, the smoke-releasing particle unit 4, the blocking and cooling unit 5, and the filtering unit 3 into the cigarette outer tube 1, so that the induction heating unit 6 is located inside the smoke-releasing particle unit 4, and rely on the blocking and cooling unit 5 and the blocking unit 2 to block the two ends of the smoke-releasing particle unit 4 respectively, to obtain a cigarette product.

[0077] To verify the effectiveness of the sensor-containing granular heated cigarette product provided in this embodiment, the applicant used a granular heated cigarette product provided in this embodiment containing the third structural form of the induction heating unit 6 as a sample and a granular heated cigarette product without the induction heating unit 6 as a control. The two were compared to obtain curves showing the smoke emission and smoke temperature of each product as a function of puff time. The curves showing the smoke emission as a function of puff time are shown in FIG5 , and the curves showing the smoke temperature as a function of puff time are shown in FIG6 . As can be seen from FIG5 and FIG6 , under the same conditions, the granular heated cigarette containing the induction heating unit 6 has a more sufficient smoke emission and a lower smoke temperature than the granular heated cigarette without the induction heating unit 6. The granular heated cigarette containing the induction heating unit 6 has a significant advantage in both smoke emission and smoke temperature.

[0078] At the same time, the applicant used the three structural forms of the induction heating unit 6 provided in this embodiment and built into the tobacco product as samples of the induction heating unit 6, namely the first induction heating unit 6 sample, the second induction heating unit 6 sample, and the third induction heating unit 6 sample, and used the traditional induction heating unit 6 installed in the heated smoking device as the induction heating unit 6 reference example. The two were compared, and graphs of the temperature changes of the two as a function of heating time were obtained. The graphs of the temperature changes of the three structural forms of the induction heating unit 6 samples and the reference example are shown in Figures 7 to 9. As can be seen from Figures 7 to 9, under the same conditions, the temperature of the induction heating unit 6 built into the tobacco product provided in this embodiment is higher than that of the induction heating unit 6 installed in the heated smoking device, indicating that the induction heating unit 6 built into the tobacco product provided in this embodiment has a better heating effect.

[0079] In addition, in order to verify the degree of influence of the granular heated cigarette product containing the sensor provided in this embodiment on the temperature of the shell of the heated smoking device, the applicant used the granular heated cigarette product containing the induction heating unit 6 provided in this embodiment as a sample, and the granular heated cigarette product without the induction heating unit 6 as a control example, and compared the two to obtain curves of the change of the shell temperature of the heated smoking device with the puffing time when the two were smoked. Among them, three types of granular heated cigarette products containing three structural forms of induction heating units 6 were respectively used as three types of samples, and the three types of samples were respectively the first type of samples, the second type of samples and the third type of samples, and the puffing mode was divided into two types of puffing modes: single puffing and continuous puffing, and compared with the control example respectively, to obtain curves of the change of the shell temperature of the heated smoking device with the puffing time when each type of sample and the control example were smoked, see Figures 10 to 15. As can be seen from Figures 10 to 15, under the same conditions, compared with the granular heated cigarette without the induction heating unit 6, the granular heated cigarette product with the sensor provided in this embodiment has a lower temperature of the heating cigarette shell when smoked, which can effectively prevent scalding, further verifying that its heat utilization rate is higher.

[0080] The above are only preferred embodiments of the present invention and are 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 scope of protection of the present invention.
