Description

Adaptive airflow heating smoking device and control method Technical Field

The 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

The heating method of existing heat-not-burn tobacco utensils is mainly resistive heating, which is further divided into central heating and circumferential heating. The central heating tobacco utensils have high energy utilization, but they do not heat the cigarettes sufficiently, and there is also the disadvantage that tobacco residues are easily left in the flue and are difficult to clean. Circumferential heating tobacco utensils improve the utilization of cigarettes because the heat radiates from the circumference to the center, but the heat loss is high, and the paper smell may be produced during the heating process, which will cause a bad experience for consumers. Based on the above reasons, an airflow heating tobacco utensils have emerged in the industry. By installing a heating component at the bottom of the tobacco utensils, the flowing air generated by the consumer's inhalation is heated to heat the tobacco core segment. Since air is used as a medium to heat the tobacco, the tobacco has a large heating area and high heating efficiency. At the same time, the tobacco does not come into direct contact with the heating plate, which solves the problem of tobacco residues being difficult to clean.

Since the airflow of existing airflow heating tobacco products is generated by consumers' inhalation, the heated air enters from the bottom of the cigarette, but the core segment has a certain heat-cutting ability. When the airflow passes through the core segment, the temperature of different parts of the core segment is significantly different. Therefore, the heating release of the core segment is mainly concentrated in the lower half of the core segment, while the utilization rate of the upper half of the core segment is not high. At the same time, repeated baking of the lower half of the core segment will produce a burnt smell, which brings a bad consumer experience. In addition, different specifications and core segment materials have different heat-cutting capabilities. The existing airflow heating tobacco products are poorly adaptable to cigarettes of different circumferences, lengths, and core segment materials.

The present invention is proposed for this purpose.

The method for using the adaptive airflow heating smoking device of the present invention comprises the following steps:

The cigarette 10 is inserted into the first cigarette clamp 103, the second cigarette clamp 104 and the third cigarette clamp along the slope. 105; the heating strip 205 in the airflow heating assembly 2 is heated and heated, the duct fan 4 starts to output the airflow, and the gas flow rate sensor 116 detects the gas flow rate; the first temperature sensor 110, the second temperature sensor 111, the third temperature sensor 112 and the fourth temperature sensor 113 measure four temperatures from top to bottom; according to the relationship between the gas flow rate and the four temperatures, the heat cut coefficient of the core section of the cigarette 10 can be obtained; according to the heat cut coefficient, the corresponding flow rate curve is matched, and then the heating strip 205 is heated to the required temperature, and the whole preheating process is completed;

When smoking cigarette 10, the suction sensor 108 transmits a signal to the duct fan 4, and the duct fan 4 outputs a 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 puff data detected by the suction sensor 108 is fed back to the heating component 2 and the duct fan 4 in real time, and the flow rate curve and the heating curve are corrected; 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.

In the adaptive airflow heating smoking device of the present invention, the cigarette 10 is inserted between the first cigarette clamp 103, the second cigarette clamp 104 and the third cigarette clamp 105. Since the upper ends of the three cigarette clamps are all inwardly inclined arc surfaces, when the cigarette 10 is inserted, the bottoms of the three cigarette clamps slide on the three slide rails 109 of the air filter 114, and compress their respective springs 107. When the cigarette 10 is pulled out, under the action of the springs 107, the three cigarette clamps move inward along the three slide rails, and return to the initial position under the limit position limit of the three limit blocks 115. When a cigarette with a larger circumference is used, the compression amount of the three springs 107 increases, and the cigarette can still be stably clamped. A highly flexible, temperature-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, 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.

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, and the cavity insulation sleeve 201 is installed on the periphery of the airflow and heating cavity, and has an interference fit with the cavity. The beneficial effect is that it keeps the airflow heating component warm and saves energy. An airflow channel 204 is arranged in the second cavity 203. The shape of the airflow channel 204 is the same as that of the Tesla valve. The beneficial effect is that it increases the airflow heating distance and ensures that the airflow direction enters from the bottom of the airflow heating component 2 and is output 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; a heating strip 205 is printed on the airflow channel 204, which has the beneficial effect of improving the heating efficiency while reducing the size of the heating component; the first cavity 202 is also arranged with an airflow channel and a heating strip, which is a mirror image of the second cavity 203.

Four temperature sensors are arranged in the flue, and the control method of the smoking device is as follows: after the consumer inserts the cigarette, the three cigarette clamps clamp the cigarette, and after power is turned on, the heating strip 205 is heated to a temperature T _{0 ,} which is lower than the smoke volatilization temperature of the smoke core section, and will not cause smoke loss in the smoke core section. The duct fan 4 starts to output the airflow, and the gas flow rate sensor 116 arranged in the flue detects the gas flow rate V ₀ . The temperatures of the four temperature sensors arranged in the flue from top to bottom are T ₁₀ , T ₂₀ , T ₃₀ , and T ₄₀ , respectively. According to the relationship between V ₀ and T ₁₀ , T ₂₀ , T ₃₀ , and T ₄₀ , the heat cut coefficient ξ of the cigarette core section can be obtained, and the corresponding flow rate curve L can be matched according to the heat cut coefficient ξ. Then, the heating strip 205 in the airflow heating component 2 is heated to a temperature T ₀₁ , and the temperature T ₀₁ can volatilize the smoke in the smoke core section, and the whole preheating process is completed. When a consumer smokes a cigarette, the suction 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 triggered and started only during the suction process, and stops during the suction interval to avoid smoke waste. At the same time, the heating component 2 continues to heat according to the preset heating curve, and the suction sensor 108 detects the number of puffs. The puff data 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 L and the heating curve. Different gas flow rates correspond to different heating positions of the cigarette core segment of the cigarette 10. When the gas flow rate is large, 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 the signal to the ducted fan 4 at the same time to ensure that the utilization rate of the cigarette core segment is maximized. Preferably, heating the cigarette core segment from top to bottom can avoid the burnt smell caused by over-baking at the lower end of the cigarette core segment, so the air supply rate of the ducted fan 4 decreases step by step. When the four temperature sensors detect that the temperature reaches the target value in turn, the smoke release of the entire smoke core section is completed and the smoking ends.

The present invention is further explained by taking a thin-sheet cigarette core segment with a larger circumference and a longer length as an example to heat a cigarette 10. 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 pad 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 T ₀ , the duct fan 4 starts to output airflow, and the gas flow rate sensor 116 detects the gas flow rate V ₀ . The temperatures of the four temperature sensors 110, 111, 112, and 113 arranged in the flue are _T10 , _T20 , _T30 , and _T40 respectively. According to the relationship between _V0 and _T10 , _T20 , _T30 , and _T40 , the cross section of the cigarette core segment can be obtained. Thermal coefficient ξ, according to the cut-off thermal coefficient ξ, the corresponding flow velocity curve L is matched. Then the heating strip 205 in the airflow heating component 2 is heated to the temperature T ₀₁ , and the whole preheating process is completed. When the consumer smokes a cigarette, the puff sensor 108 detects it and transmits the signal to the duct fan 4, which outputs the flow velocity according to the flow velocity curve L preheated in the preheating stage. The duct fan 4 is only triggered to start during the puffing process and shuts down during the puff interval to avoid waste of 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 duct fan 4 in real time to correct the flow velocity curve L and the heating curve. Four temperature sensors detect the temperature of the upper, middle, lower and lower parts of the core segment respectively, and their temperatures are T ₁ , T ₂ , T ₃ and T ₄ respectively. The upper part of the core segment is first heated with a faster gas flow rate, and the temperature sensor of the upper part of the core segment is used for real-time feedback. After the heating is completed, the upper, middle and lower parts of the core segment are heated respectively, and the temperature sensors of each part are used for real-time feedback and adjustment, and finally the whole smoking process is completed. The corresponding relationship between the gas flow rate and the number of puffs for heating cigarettes with larger circumference, larger length and thin core segment is shown in Figure 10. It can be seen that the gas flow rate decreases with the increase of the number of 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 entire smoking time is shown in FIG11. It can be seen that the temperature curves detected at the upper, upper middle, lower middle, and lower parts of the core segment first increase to reach a peak value and then decrease. However, the temperature peak times of the four parts of the core segment are different. The time for the upper, upper middle, lower middle, and lower parts of the core segment to reach the temperature peak increases successively, which means that different parts of the core segment are baked emphatically at different times, thereby increasing the utilization rate of the core segment and avoiding the bad experience of burnt smell caused by repeated baking of one part.

The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
