Description
Adaptive airflow heating smoking device and control method Technical Field
[0001] The present invention belongs to the technical field of tobacco, and in particular relates to an adaptive airflow heating smoking device and a control method thereof. Background Art
[0002] The heating method of existing heat-not-burn tobacco products is mainly resistive heating, which is further divided into central heating and circumferential heating. Among them, central heating tobacco products have high energy utilization, but they do not heat the cigarettes sufficiently. At the same time, there is a disadvantage that tobacco residue is easy to remain in the flue and is difficult to clean. Circumferential heating tobacco products improve the utilization rate of cigarettes because heat radiates from the circumference to the center, but the heat loss is high, and the heating process may produce a paper smell that gives consumers a bad experience. For the above reasons, an airflow heating tobacco product has emerged in the industry. By installing a heating component at the bottom of the tobacco product, the flowing air generated by the consumer's inhalation is heated to heat the tobacco core section. Since air is used as the medium to heat the tobacco, the heated area of the tobacco is large and the heating efficiency is high. At the same time, the tobacco does not directly contact the heating plate, which solves the problem of tobacco residue being difficult to clean.
[0003] Because the airflow in existing airflow-heated smoking devices is generated by the consumer's inhalation, heated air enters the bottom of the cigarette. However, the core segment has a certain heat-trapping capacity, and as the airflow passes through the core segment, the temperature of different parts of the core segment varies significantly. Therefore, the heat release to the core segment is mainly concentrated in the lower half of the core segment, while the upper half is not highly utilized. Furthermore, the repeated heating of the lower half of the core segment produces a burnt smell, resulting in a poor consumer experience. Furthermore, different specifications and core segment materials have different heat-trapping capabilities, making existing airflow-heated smoking devices less adaptable to cigarettes of varying circumferences, lengths, and core segment materials.
[0004] The present invention is proposed for this purpose.

[0040] The method for using the adaptive airflow heating smoking device of the present invention comprises the following steps:
[0041] The cigarette 10 is inserted along the sloped opening into the cylindrical space formed by the first, second, and third cigarette holders 103, 104, and 105. The heating strips 205 in the airflow heating assembly 2 are heated, the ducted fan 4 starts to output airflow, and the gas flow rate sensor 116 detects the gas flow rate. The first, second, third, and fourth temperature sensors 110, 111, 112, and 113 measure four temperatures from top to bottom. The relationship between the gas flow rate and the four temperatures can be used to determine the heat cutoff coefficient of the cigarette core section. The heat cutoff coefficient is matched to the corresponding flow rate curve, and the heating strips 205 then heat the cigarette to the required temperature, completing the entire preheating process.
[0042] When smoking cigarette 10, the suction sensor 108 transmits a signal to the ducted fan 4, and the ducted fan 4 outputs the gas flow rate according to the flow rate curve preheated in the preheating stage; at the same time, the heating component 2 continues to heat according to the pre-set heating curve; the number of puffs detected by the suction sensor 108 is fed back to the heating component 2 and the ducted fan 4 in real time to correct the flow rate curve and the heating curve; the four temperature sensors respectively detect the temperature of the upper, upper middle, lower middle and lower parts of the cigarette core segment of the cigarette 10, first heat the upper part of the cigarette core segment with a faster gas flow rate, and then heat the upper middle, lower middle and lower parts of the cigarette core segment after the heating is completed, and adjust the temperature sensors in each part in real time to complete the entire suction process.
[0043] In the adaptive airflow heating smoking device of the present invention, a cigarette 10 is inserted between the first, second, and third cigarette clamps 103, 104, and 105. Because the upper ends of these three clamps are all inwardly sloped, curved surfaces, when a cigarette 10 is inserted, the bottoms of the three clamps slide on the three slide rails 109 of the air filter 114, compressing their respective springs 107. When a cigarette 10 is removed, the springs 107 act to move the three clamps inward along the three slide rails, then return to their initial positions under the extreme position restraints of the three stoppers 115. When using cigarettes with larger circumferences, the compression of the three springs 107 increases, maintaining a stable grip on the cigarette. A highly flexible, heat-resistant sealing pad 117 is provided at the upper end of the flue insulation sleeve 101, which has the beneficial effect of ensuring the sealing effect of the airflow when inserting cigarettes of different circumferences, and ensuring that the airflow passing through the cigarettes enters the filter end of the cigarette from the bottom of the smoking device and is output; at the same time, the flue 101 has a certain length, which ensures that the adaptive airflow heating smoking device can adapt to cigarettes of different circumferences and lengths.
[0044] As shown in Figure 7, the first cavity 202 and the second cavity 203 of the airflow heating component 2 are connected by screws to form a complete airflow and heating cavity. The cavity insulation sleeve 201 is installed on the periphery of the airflow and heating cavity and has an interference fit with the cavity. Its beneficial effect is to keep the airflow heating component warm and save energy. The second cavity 203 is arranged with an airflow channel 204. The shape of the airflow channel 204 is the same as that of the Tesla valve. Its beneficial effect is to increase the airflow heating distance and ensure that the airflow direction enters from the bottom of the airflow heating component 2 and outputs from the top. At the same time, when the airflow passes through the Tesla valve-shaped airflow channel 204, it has a certain acceleration function. The airflow channel 204 is printed with a heating strip 205. Its beneficial effect is to improve the heating efficiency and reduce the size of the heating component. The first cavity 202 is also arranged with an airflow channel and a heating strip, which are mirror images of the second cavity 203.
[0045] Four temperature sensors are placed in the flue. The control method for the smoking device is as follows: After the consumer inserts a cigarette, the three cigarette holders clamp it tightly. After power is applied, the heating strip 205 is heated to temperature T0. T0 is lower than the smoke volatilization temperature of the cigarette core, which will not cause smoke loss in the cigarette core. The duct fan 4 starts to output airflow, and the gas flow rate sensor 116 placed in the flue detects the gas flow rate V0. The four temperature sensors placed in the flue are T0 from top to bottom. 10 、T 20 、T 30 、T 40 , according to V0 and T 10 、T 20 、T 30 、T 40The relationship between the heat cut coefficient ξ of the cigarette core segment can be obtained, and the corresponding flow velocity curve L is matched according to the heat cut coefficient ξ. Then the heating strip 205 in the air flow heating component 2 is heated to the temperature T 01 , T 01 The temperature can volatilize the smoke in the cigarette core segment, completing the entire preheating process. When the consumer smokes the cigarette, the puff sensor 108 detects it and transmits a signal to the ducted fan 4. The ducted fan 4 outputs the flow rate according to the flow rate curve L preheated in the preheating stage. The ducted fan 4 is only triggered to start during the puffing process and shuts down during the puff interval to avoid wasting smoke. At the same time, the heating component 2 continues to heat according to the pre-set heating curve, and the puff sensor 108 detects the number of puffs. The puff data detected by the puff sensor 108 is fed back to the heating component 2 and the ducted fan 4 in real time to correct the flow rate curve L and the heating curve. Different gas flow rates correspond to different heating parts of the cigarette core segment 10. When the gas flow rate is higher, the heating of the cigarette core segment is closer to the upper end. Four temperature sensors detect the heating temperature of the four parts of the cigarette core segment and transmit signals to the ducted fan 4 to ensure that the utilization rate of the cigarette core segment is maximized. Preferably, heating the smoke core from top to bottom can prevent the burnt smell at the lower end of the smoke core caused by overheating. Therefore, the air supply rate of ducted fan 4 is gradually reduced. When the four temperature sensors detect that the temperature has reached the target value, the smoke release of the entire smoke core segment is completed, and the smoking ends.
[0046] The present invention will be further explained by taking a thin-film cigarette core segment with a larger circumference and a longer length as an example. The cigarette 10 is inserted into the smoking device, and the three cigarette clamps are forced to move along the slide rail 109 toward the inner wall of the flue 102, while compressing the three springs 107 to clamp the cigarette 10. The highly flexible and heat-resistant sealing gasket 117 on the flue insulation sleeve 101 fits tightly with the filter end of the cigarette 10 to ensure sealing. The heating strip 205 in the airflow heating assembly 2 is heated to T0, the duct fan 4 starts to output airflow, and the gas flow rate sensor 116 detects the gas flow rate V0. The temperatures of the four temperature sensors 110, 111, 112, and 113 arranged in the flue from top to bottom are T 10 、T 20 、T 30 、T 40 , according to V0 and T 10 、T 20 、T 30 、T 40 The relationship between the heat cut coefficient ξ of the cigarette core segment can be obtained, and the corresponding flow velocity curve L is matched according to the heat cut coefficient ξ. Then the heating strip 205 in the air flow heating component 2 is heated to the temperature T 01The entire preheating process is complete. When a consumer takes a puff, the puff sensor 108 detects it and transmits a signal to the ducted fan 4, which then outputs a flow rate according to the preheating flow rate curve L. The ducted fan 4 is activated only during the puff phase and shuts down between puffs to prevent smoke waste. Simultaneously, the heating assembly 2 continues heating according to the pre-set heating curve. The puff sensor 108 measures the number of puffs. This puff data is fed back to the heating assembly 2 and the ducted fan 4 in real time, allowing corrections to the flow rate curve L and the heating curve. Four temperature sensors measure the temperatures of the upper, upper middle, lower middle, and lower parts of the cigarette core, respectively. The temperatures are T1, T2, T3, and T4. The upper part of the cigarette core is first heated at a faster gas flow rate, with real-time feedback from the upper temperature sensor. After heating is complete, the upper middle, lower middle, and lower parts of the cigarette core are heated separately, with real-time feedback from the temperature sensors in each part adjusting the temperature, completing the entire puffing process. The relationship between gas flow rate and the number of puffs for heating cigarettes with larger circumferences, longer lengths, and thinner core segments is shown in Figure 10. It can be seen that the gas flow rate decreases with increasing puffs. The relationship between the temperatures T1, T2, T3, and T4 detected at the upper, upper middle, lower middle, and lower parts of the core segment and the total puff time is shown in Figure 11. It can be seen that the temperature curves detected at the upper, upper middle, lower middle, and lower parts of the core segment all increase first, reach a peak, and then decrease. However, the temperature peak times of these four parts of the core segment are different. The time it takes for the upper, upper middle, lower middle, and lower parts of the core segment to reach the temperature peak increases in sequence. This means that different parts of the core segment are baked at different times, thereby increasing the core segment utilization rate and avoiding the unpleasant burnt smell caused by repeatedly baking the same part.

It should be noted that the above preferred embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention should be determined by the scope defined in the claims. Persons skilled in the art will appreciate that improvements and modifications may be made without departing from the spirit and scope of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
