Description

Technical Field

[0001] This invention belongs to the field of tobacco technology, specifically relating to an adaptive airflow heating smoking device and its control method. Background Technology

[0002] Existing heated tobacco products primarily use resistance heating, which is further divided into center heating and circumferential heating. Center heating devices have high energy utilization, but they don't heat the tobacco sufficiently and have the drawback of leaving tobacco residue in the duct that is difficult to clean. Circumferential heating devices, because heat radiates from the circumference to the center, have improved tobacco utilization, but heat loss is higher, and a papery smell may be produced during the heating process, leading to a negative consumer experience. Based on these reasons, an airflow-heated tobacco product has emerged. This product uses a heating element installed at the bottom of the device to heat the airflow generated by the consumer's inhalation, which in turn heats the tobacco coil. Since air acts as the medium for heating the tobacco, the tobacco has a large heating area and high heating efficiency. Furthermore, the tobacco does not directly contact the heating element, solving the problem of difficult-to-clean tobacco residue.

[0003] Because the airflow in existing air-heated smoking devices is generated by the consumer's inhalation, and the heated air enters from the bottom of the cigarette, but the filler section has a certain heat-trapping capacity, the temperature of different parts of the filler section varies significantly as the airflow passes through it. Therefore, the heating of the filler section is mainly concentrated in the lower half, while the utilization rate of the upper half is low. Furthermore, repeated heating of the lower half of the filler section produces a burnt taste, leading to a poor consumer experience. In addition, different specifications and filler materials have varying heat-trapping capacities, resulting in poor adaptability of existing air-heated smoking devices to cigarettes of different circumferences, lengths, and filler materials.

[0004] This invention is proposed for this purpose. Summary of the Invention

At the same time, the heating component 2 continues to heat according to the preset 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. Four temperature sensors detect the temperature of the upper, upper-middle, lower-middle, and lower parts of the cigarette core section of cigarette 10.

[0032] like Figure 1-8 As shown, an adaptive airflow heating smoke appliance of the present invention includes a flue assembly 1, an airflow heating assembly 2, a connector 3, a duct fan 4, and a smoke appliance base 5; the flue assembly 1 is arranged on the upper part of the airflow heating assembly 2; the lower end of the airflow heating assembly 2 is connected to the duct fan 4 through the connector 3; the duct fan 4 is arranged on the smoke appliance base 5.

[0033] like Figure 5-6 As shown, the flue assembly 1 includes: multiple cigarette holders, a first air filter 114, a flue 102, and a flue insulation sleeve 101; the multiple cigarette holders are the same size and shape, forming a cylindrical wall split along the axial direction, with the upper wall surface being an inward slope; the multiple cigarette holders are arranged vertically to form a cylindrical shape with a variable diameter, the outer periphery of which is the cylindrical flue 102, and the outer periphery of the flue 102 is the flue insulation sleeve 101; each cigarette holder has its own slide rail 109 at its bottom, and each cigarette holder has a spring 107 installed in the middle of its outer wall; each spring 107 is fixed to the inner wall of the flue 102 by a spring base 106; each slide rail 109 has a limiting block 115; the first air filter 114 is fixedly arranged at the bottom of the flue 102; the slide rail 109 and the limiting block 115 are installed on the first air filter 114.

[0034] A suction sensor 108 and a gas flow rate sensor 116 are installed at the lower end of the flue 102; a flexible sealing gasket 117 is installed at the upper end of the flue insulation sleeve 101; and several temperature sensors are arranged on the inner wall of one of the cigarette holder blocks.

[0035] The cigarette holder consists of three parts: a first cigarette holder 103, a second cigarette holder 104, and a third cigarette holder 105. Four temperature sensors are arranged at equal intervals on the inner wall of the first cigarette holder 103, from top to bottom: a first temperature sensor 110, a second temperature sensor 111, a third temperature sensor 112, and a fourth temperature sensor 113. The surfaces of the four temperature sensors are in direct contact with the cigarette 10 inserted into the flue 102.

[0036] like Figure 7As shown, the airflow heating assembly 2 includes a cavity insulation sleeve 201, a first cavity 202, and a second cavity 203; the first cavity 202 and the second cavity 203 are combined to form a complete airflow and heating cavity; the cavity insulation sleeve 201 wraps around the airflow and heating cavity; an airflow channel 204 is arranged inside the second cavity 203, and the shape of the airflow channel 204 is the same as that of a Tesla valve; a heating strip 205 is printed on the airflow channel 204; the first cavity 202 also has an airflow channel and a heating strip arranged inside, mirror-symmetrical to the second cavity 203.

[0037] like Figure 3-4 As shown, the upper end of the connector 3 is a rectangular interface and the lower end has an external thread; the upper rectangular interface of the connector 3 is interference-fitted with the rectangular hole at the lower end of the airflow heating component 2, and the lower external thread is connected to the duct fan 4 through an internal thread; a second air filter 8 is installed at the air inlet at the bottom of the duct fan 4.

[0038] like Figures 1-2 As shown, the smoking device also includes a battery 6, a support frame 7, and a smoking device housing 9; the support frame 7 is fixed inside the smoking device housing 9, and the support frame 7 is used to fix the battery 6 and the airflow heating component 2; the smoking device housing 9 and the smoking device base 5 are connected together by a snap fastener.

[0039] The method of using the adaptive airflow heating smoke appliance of the present invention includes the following steps:

[0040] The cigarette 10 is inserted into the cylindrical space formed by the first cigarette clamp 103, the second cigarette clamp 104, and the third cigarette clamp 105 along the sloping opening; the heating strip 205 in the airflow heating assembly 2 heats up, the duct fan 4 starts and outputs airflow, and the gas velocity sensor 116 detects the gas velocity; 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; based on the relationship between the gas velocity and the four temperatures, the heat cutoff coefficient of the cigarette core section of the cigarette 10 can be obtained; based on the heat cutoff coefficient, the corresponding velocity curve is matched, and then the heating strip 205 heats it to the required temperature, completing the entire preheating process;

[0041] When smoking cigarette 10, the suction sensor 108 transmits a signal to the ducted fan 4, which outputs a gas flow rate according to the preheating flow rate curve. At the same time, the heating component 2 continues to heat according to the preset 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. Four temperature sensors detect the temperature of the upper, upper-middle, lower-middle, and lower parts of the cigarette core section of cigarette 10. The upper part of the cigarette core section is heated first with a faster gas flow rate. After heating, the upper-middle, lower-middle, and lower parts of the cigarette core section are heated respectively. The temperature of each part is adjusted in real time by the temperature sensors, and finally the entire smoking process is completed.

[0042] In this invention, an adaptive airflow heated smoking device allows a cigarette 10 to be inserted between three clamping blocks: a first clamping block 103, a second clamping block 104, and a third clamping block 105. Since the upper ends of the three clamping blocks are inwardly sloping arc-shaped surfaces, when the cigarette 10 is inserted, the bottoms of the three clamping blocks slide on the three slide rails 109 of the air filter 114, simultaneously compressing their respective springs 107. When the cigarette 10 is pulled out, under the action of the springs 107, the three clamping blocks move inward along the three slide rails, and simultaneously return to their initial positions under the extreme position restraint of the three limiting blocks 115. When using a cigarette with a larger circumference, the compression of the three springs 107 increases, yet the cigarette remains stably clamped. The upper end of the flue insulation sleeve 101 is equipped with a highly flexible and heat-resistant sealing gasket 117. Its beneficial effects are: when cigarettes of different circumferences are inserted, the airflow sealing effect can still be guaranteed, ensuring that the airflow through the cigarette enters from the bottom of the smoking device and exits from the cigarette filter end; 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.

[0043] like Figure 7 As shown, the first cavity 202 and the second cavity 203 of the airflow heating assembly 2 are connected by screws to form a complete airflow and heating cavity. A cavity insulation sleeve 201 is installed on the outer periphery of the airflow and heating cavity, with an interference fit. Its beneficial effect is to insulate the airflow heating assembly and save energy. An airflow channel 204 is arranged inside the second cavity 203. The airflow channel 204 has the same shape as a Tesla valve. Its beneficial effect is to increase the airflow heating distance and ensure that the airflow direction is from the bottom of the airflow heating assembly 2 to the top output. Simultaneously, the airflow has a certain acceleration function when passing through the Tesla valve-shaped airflow channel 204. Heating strips 205 are printed on the airflow channel 204, which has the beneficial effect of improving heating efficiency and reducing the size of the heating assembly. The first cavity 202 also has an airflow channel and heating strips arranged inside, mirroring the second cavity 203.

[0044] Four temperature sensors are installed in the flue. The smoking device is controlled as follows: after the consumer inserts the cigarette, it is clamped by three cigarette holders. After power is applied, the heating strip 205 heats the cigarette to temperature T0. T0 is lower than the vapor evaporation temperature of the cigarette core, preventing any loss of vapor from the core. The duct fan 4 starts and outputs airflow, which is detected by the gas velocity sensor 116 installed in the flue, showing the gas velocity V0. The four temperature sensors installed in the flue, from top to bottom, measure the following temperatures: T... 10 T 20 T 30 T 40 According to V0 and T 10 T 20 T 30 T 40 Based on the relationship, the heat cutoff coefficient ξ of the cigarette core section can be obtained, and the corresponding flow velocity curve L can be matched according to the heat cutoff coefficient ξ. Then, the heating bar 205 in the airflow heating assembly 2 heats it to temperature T. 01 T 01 Temperature allows the smoke in the cigarette core to evaporate, completing the preheating process. When a consumer smokes the cigarette, the suction sensor 108 detects this and transmits a signal to the ducted fan 4. The ducted fan 4 outputs a flow rate according to the preheating flow rate curve L. The ducted fan 4 is only activated during the smoking process and stops during intervals to avoid wasting smoke. Simultaneously, the heating component 2 continuously heats according to a pre-set heating curve. The suction sensor 108 detects the number of puffs, and this data 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 section. When the gas flow rate is higher, the heating of the cigarette core section is closer to the upper part. Four temperature sensors detect the heating temperature of four parts of the cigarette core section and transmit the signals to the ducted fan 4 to ensure maximum utilization of the cigarette core section. Preferably, heating the core section from top to bottom avoids the burnt smell caused by over-baking at the lower end of the core section. Therefore, the airflow rate of the duct fan 4 decreases gradually. When the four temperature sensors detect that the temperature has reached the target value in sequence, the smoke release of the entire core section is complete, and the suction ends.

[0045] The invention is further explained using a thin-film cigarette core segment with a relatively large circumference and length as an example. The cigarette 10 is inserted into the smoking device, and three cigarette clamping blocks move along the slide rail 109 towards the inner wall of the flue 102 under force, while simultaneously compressing three springs 107 to clamp the cigarette 10. The highly flexible, heat-resistant sealing gasket 117 on the flue insulation sleeve 101 fits tightly against the filter end of the cigarette 10 to ensure a tight seal. The heating strip 205 in the airflow heating assembly 2 heats up to T0, the duct fan 4 starts and outputs airflow, and the gas flow rate sensor 116 detects the gas flow rate V0. The four temperature sensors 110, 111, 112, and 113 arranged inside the flue, from top to bottom, have temperatures of T0, T0, and T0, respectively.10 T 20 T 30 T 40 According to V0 and T 10 T 20 T 30 T 40 Based on the relationship, the heat cutoff coefficient ξ of the cigarette core section can be obtained, and the corresponding flow velocity curve L can be matched according to the heat cutoff coefficient ξ. Then, the heating bar 205 in the airflow heating assembly 2 heats it to temperature T. 01 The entire preheating process is complete. When the consumer smokes the cigarette, the suction sensor 108 detects this and transmits the signal to the ducted fan 4. The ducted fan 4 outputs a flow rate according to the preheating flow rate curve L. The ducted fan 4 is only activated during the smoking process and stops during intervals to avoid wasting smoke. Simultaneously, the heating component 2 continuously heats according to a pre-set heating curve. The suction sensor 108 detects the number of puffs, and this data 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. Four temperature sensors detect the temperature of the upper, upper-middle, lower-middle, and lower parts of the cigarette core section, with temperatures T1, T2, T3, and T4 respectively. First, the upper part of the cigarette core section is heated with a faster gas flow rate, with real-time feedback from the temperature sensor at the upper part. After heating is complete, the upper-middle, lower-middle, and lower parts of the cigarette core section are heated separately, with real-time adjustment based on the temperature sensors at each part. Finally, the entire smoking process is completed. The relationship between gas flow rate and number of puffs for heating cigarettes with larger circumference, larger length, and thinner core sections is as follows: Figure 10 As shown in the figure, the gas flow rate decreases with the increase of the number of suction ports. The relationship between the temperatures T1, T2, T3, and T4 measured at the upper, upper-middle, lower-middle, and lower parts of the tobacco core and the total suction time is shown in the figure. Figure 11 As shown, the temperature curves detected in the upper, upper middle, lower middle, and lower parts of the tobacco core segment all increase first to reach a peak and then decrease. However, the peak temperature times of the four parts of the tobacco core segment are different. The peak temperature times of the upper, upper middle, lower middle, and lower parts of the tobacco core segment increase in sequence. This means that different parts of the tobacco core segment are baked at different times, thereby increasing the utilization rate of the tobacco core segment and avoiding the unpleasant experience of burnt taste caused by repeated baking of one part.
