Description

Technical Field

[0001] The present invention relates to the field of atomization devices, and particularly to an aerosol generation method, apparatus, computer program product, and storage medium.

Background Art

[0002] When allowing a human to consume an aerosol generated by an aerosol generator, during the heating process, the variation range of the heating temperature affects the change of an aerosol-forming substance containing nicotine and (optionally) flavor.

[0003] In the temperature control means used in conventional aerosol generators, after the temperature of the aerosol-forming substrate has risen to the operating temperature, the temperature is maintained until the time at that stage ends. However, this means has the drawback that it is difficult to determine the operating temperature. If the operating temperature is too high, in the early stage of the inhalation time, the inhalation feeling and the quality of the aerosol are good, but in the later stage of the inhalation time, impurities are likely to increase due to excessive baking. Also, if the operating temperature is too low, in the early stage of the inhalation time, baking is insufficient, so the aerosol becomes thin or does not occur, and the inhalation feeling is also inferior.

Effects of the Invention

[0038] When implementing the technical means of the present invention, in the first stage, by controlling the heating of the first heating element, first, the temperature of the first heating element is raised to the first temperature (the highest temperature point in the first stage). As a result, sufficient preheating of the aerosol-forming substrate becomes possible, and it becomes easier to generate aerosol. Next, the temperature of the first heating element is lowered from the first temperature to the second temperature. This prevents the aerosol-forming substrate from being baked at an excessive high temperature, thus suppressing the generation of impurities and burnt odors. At the same time, in the first stage, by controlling the heating of the second heating element, the temperature of the second heating element is raised to the third temperature. As a result, the aerosol-forming substrate in the second part can be pre-baked in advance, making it easier for the aerosol-forming substrate to generate aerosol in the second stage. Also, in the second stage, by controlling the heating of the second heating element, the temperature of the second heating element is raised to the fourth temperature. At the same time, by controlling the heating of the first heating element, the temperature of the first heating element is lowered to the fifth temperature. This ensures the suction feeling during the inhalation time and the quality of the aerosol.

Mode for Carrying Out the Invention

[0041] Hereinafter, in combination with the drawings in the embodiments of the present invention, the technical means of the embodiments of the present invention will be described clearly and concisely. Needless to say, the described embodiments are only some of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained on the premise that those skilled in the art do not perform creative labor all belong to the protection scope of the present invention.

[0042] Figure 1 is a flowchart of Example 1 of the aerosol generation method in the present invention. First, as a point to be explained, the aerosol generator is provided with at least two heat sources for heating an aerosol-forming substrate (for example, a tobacco stick) during use. That is, it includes at least a first heating element and a second heating element. Correspondingly, the aerosol-forming substrate includes a first part and a second part. And the first heating element is used to heat the first part, and the second heating element is used to heat the second part. For example, in a specific embodiment, as shown in Figure 2, the aerosol-forming substrate is in one complete unit. That is, the first part 31 and the second part 32 are not physically separated. However, of course, in other embodiments, the first part 31 and the second part 32 may be two independent parts. Also, the first heating element 21 and the second heating element 22 are each a cylindrical heating element, and each is covered on the first part 31 and the second part 32 of the aerosol-forming substrate. However, of course, in other embodiments, the first heating element 21 and the second heating element 22 may be a heating sheet, a heating pin, a heating rod, a heating wire or a cable, and each may be inserted into the first part 31 and the second part 32 of the aerosol-forming substrate. Also, the first heating element 21 and the second heating element 22 may be different sections of one heating element, or two different heating elements physically spaced apart.

[0043] As shown in Figure 1, the aerosol generation method of this embodiment includes the following steps.

[0044] Step S10: In the first stage, by controlling the heating of the first heating element, the temperature of the first heating element is raised to a first temperature and then lowered to a second temperature. Also, by controlling the heating of the second heating element, the temperature of the second heating element is raised to a third temperature. The third temperature is lower than the second temperature.

[0045] In this step, in the first stage, the temperatures of both the first heating element and the second heating element start to rise from the initial temperature. The initial temperature may be room temperature, for example, 25 degrees or 0 degrees, etc.

[0046] Step S20: In the second stage, by heating and controlling the second heating element, the temperature of the second heating element is raised from the third temperature to the fourth temperature. Also, by heating and controlling the first heating element, the temperature of the first heating element is lowered from the second temperature to the fifth temperature. The fourth temperature is higher than the fifth temperature.

[0047] In the technical means of this embodiment, combining FIGS. 3A and 3B, 0 to t1 is the first stage, and t1 to t2 is the second stage. In the first stage (0 to t1), by heating and controlling the first heating element, first, the temperature of the first heating element is raised to the first temperature T1 (the highest temperature point of the first stage). Thereby, sufficient preheating of the aerosol-forming substrate becomes possible, and it becomes easier to generate an aerosol. Next, the temperature of the first heating element is continuously lowered from the first temperature T1 to the second temperature T2 (T2 < T1). Thereby, since the aerosol-forming substrate is not baked at an excessive high temperature, the generation of impurities and burnt odors is suppressed. At the same time, in the first stage (0 to t1), by heating and controlling the second heating element, the temperature of the second heating element is raised to the third temperature T3 (T3 < T2). Thereby, since the second part of the aerosol-forming substrate can be pre-baked, it becomes easier for the second part to generate an aerosol in the second stage. Also, in the second stage (t1 to t2), by heating and controlling the second heating element, the temperature of the second heating element is raised to the fourth temperature T4 (the highest temperature point of the second stage). At the same time, by heating and controlling the first heating element, the temperature of the first heating element is lowered to the fifth temperature T5 (T5 < T4). Thereby, the inhalation feeling during inhalation time and the quality of the aerosol are guaranteed.

[0048] Furthermore, the first temperature is between 150 and 300 °C (including 150 °C and 300 °C), and the second temperature is between 150 and 300 °C (including 150 °C and 300 °C). The difference between the second temperature and the first temperature is between 5 and 100 °C (including 5 °C and 100 °C). Also, the third temperature is between 50 and 200 °C (including 50 °C and 200 °C), and the fourth temperature is between 150 and 300 °C (including 150 °C and 300 °C).

[0049] In a specific embodiment, as shown in FIGS. 3A and 3B, the first temperature is 300° C., the second temperature is 240° C., the third temperature is 100° C., the fourth temperature is 290° C., and the fifth temperature is 200° C. Thus, in the first stage, for the first heating element, first, by raising the temperature to 300° C. (the highest temperature point in the first stage), the first part of the aerosol-forming substrate is sufficiently preheated. Thereby, it becomes easier for the first part to generate aerosol in the first stage. Next, in order to prevent the first part from being baked at an excessive high temperature, by lowering the temperature to 240° C., the generation of impurities and burnt odor is suppressed. Also, for the second heating element, by raising the temperature to 100° C., the second part of the aerosol-forming substrate is preheated so as to generate aerosol in the second stage. In the second stage, for the second heating element, by raising the temperature to 290° C., the second part is sufficiently heated to make it easier to generate aerosol. Also, for the first heating element, by lowering the temperature to 200° C., the situation where the first part generates impurities or burnt odor due to excessive high-temperature baking is avoided. Thereby, the inhalation comfort during the inhalation time and the quality of the aerosol are guaranteed.

[0050] Furthermore, in an alternative embodiment, by controlling the heating of the first heating element in step S10, raising the temperature of the first heating element to the first temperature and then lowering it to the second temperature specifically includes the following. That is, by controlling the heating of the first heating element, in the first period of the first stage, the temperature of the first heating element is raised to the first temperature. And in the second period of the first stage, the temperature of the first heating element is continuously lowered from the first temperature to the second temperature, or first the temperature of the first heating element is lowered to the second temperature and then maintained at the second temperature. And the first period is shorter than the second period.

[0051] In a specific embodiment, as shown in FIG. 3B, 0 to t11 is the first period of the first stage, and t11 to t1 is the second period of the first stage. Since the first period (for example, 10 s) is shorter than the second period (for example, 2 minutes), in the first period of the first stage, the temperature of the first heating element can be rapidly increased to the first temperature T1 to rapidly preheat the first part of the aerosol-forming substrate. Thereby, the lack of mouthfeel and aerosol concentration due to insufficient baking of the first part in the starting stage is avoided. Also, in the second period of the first stage, the temperature of the first heating element continues to decrease from the first temperature T1 to the second temperature T2. Thereby, it is possible to avoid the situation where the first part generates impurities and a burnt odor due to the temperature being too high.

[0052] In another specific embodiment, as shown in FIG. 5, 0 to t11 is the first period of the first stage, and t11 to t1 is the second period of the first stage. Since the first period (for example, 10 s) is shorter than the second period (for example, 2 minutes), in the first period of the first stage, the temperature of the first heating element can be rapidly increased to the first temperature T1 to rapidly preheat the first part of the aerosol-forming substrate. Thereby, the lack of mouthfeel and aerosol concentration due to insufficient baking in the starting stage is avoided. Also, in the second period of the first stage, the temperature of the first heating element first decreases to the second temperature T2 during the period of t11 to t12, and then is maintained at the second temperature T2 during the period of t12 to t1. Also in this case, it is possible to avoid the situation where the first part generates impurities and a burnt odor due to the temperature being too high.

[0053] Furthermore, in an alternative embodiment, increasing the temperature of the second heating element to a third temperature by controlling the heating of the second heating element in step S10 includes the following. That is, in the second period of the first stage, by controlling the heating of the second heating element, first the temperature of the second heating element is increased to the third temperature and then maintained at the third temperature, or the temperature of the second heating element is continuously increased to the third temperature.

[0054] In this embodiment, in the process where the temperature of the first heating element continues to decrease from the first temperature T1 to the second temperature T2, that is, in the second period, the heating control of the second heating element is started. For example, as shown in FIG. 3A, starting from the time point t13 in the second period (the time point t13 is within the second period), by starting the heating control of the second heating element, the temperature is first raised to the third temperature T3 and then maintained at the third temperature T3. Thereby, it becomes possible to avoid a situation where the first part of the aerosol-forming substrate generates impurities or a burnt smell because the temperature is too high (this is also because when the heating of the second heating element starts, the heat of the second part of the aerosol-forming substrate is transmitted to the first part). In addition, a situation where the aerosol-generating substance is consumed too early because the timing at which the second part generates aerosol is too early, and the concentration of the aerosol generated by the second part becomes excessively low in the later stage of inhalation is also avoided. Of course, in other embodiments, the temperature of the second heating element may continue to rise to the third temperature.

[0055] Regarding the heating graph of the second heating element in the first stage of FIGS. 3A and 3B, further, as a point to be explained, the temperature of the second heating element in FIG. 3B has started to rise from the start of the first period, but this is a passive temperature rise caused by heat conduction from the first heating element. Therefore, only the temperature rise in the second period is the temperature rise accompanying the active heating of the second heating element. For example, in the embodiment shown in FIG. 4, the first heating element 21 and the second heating element 22 have an integrated tubular structure. And, there are a plurality of holes 23 between the first heating element 21 and the second heating element 22 to partially open the gap. However, of course, in other embodiments, the gap may be partially opened through a groove. Thereby, since the interaction of the temperature fields of the first heating element 21 and the second heating element 22 becomes small, it becomes easy to control the temperature of the first heating element 21 or the second heating element 22 alone. And, since the relative positions of the first heating element 21 and the second heating element 22 become relatively clear, manufacturing and installation become easy.

[0056] Furthermore, in an alternative embodiment, increasing the temperature of the second heating element from the third temperature to the fourth temperature by controlling the heating of the second heating element includes the following. That is, by controlling the heating of the second heating element, the temperature of the second heating element is increased from the third temperature to the fourth temperature during the third period of the second stage. Also, during the fourth period of the second stage, the temperature of the second heating element is maintained at the fourth temperature or the temperature of the second heating element is increased from the fourth temperature to the sixth temperature. The third period and the fourth period are two periods obtained by partitioning the second stage in a first partitioning method. And the third period is shorter than the fourth period.

[0057] In a specific embodiment, as shown in FIG. 5, the second stage (t1 to t2) may be partitioned into a third period (t1 to t21) and a fourth period (t21 to t2) by a first partitioning method. And the third period is shorter than the fourth period. For the second heating element in the second stage, by performing heating control, the temperature in the third period is increased from the third temperature T3 to the fourth temperature T4, and the temperature in the fourth period is maintained at the fourth temperature T4. Since the third period is shorter than the fourth period, rapid preheating of the second heating element can avoid the lack of mouthfeel and aerosol concentration caused by insufficient baking of the second part of the aerosol-forming substrate.

[0058] In a specific embodiment, as shown in FIG. 6, similarly in this case, the second stage (t1 to t2) is partitioned into a third period (t1 to t21) and a fourth period (t21 to t2). And the third period is shorter than the fourth period. For the second heating element in the second stage, by performing heating control, the temperature in the third period is increased from the third temperature T3 to the fourth temperature T4, and the temperature in the fourth period is increased from the fourth temperature T4 to the sixth temperature T6. Since the third period is shorter than the fourth period, rapid preheating of the second heating element can avoid the lack of mouthfeel and aerosol concentration caused by insufficient baking of the second part of the aerosol-forming substrate. Also, since the second heating element also increases in temperature during the fourth period, the lack of mouthfeel and aerosol concentration caused by insufficient baking can be avoided during the subsequent heating process.

[0059] Furthermore, in an alternative embodiment, reducing the temperature of the first heating element from the second temperature to the fifth temperature by controlling the heating of the first heating element includes the following. That is, by controlling the heating of the first heating element, in the fifth period of the second stage, the temperature of the first heating element is reduced from the second temperature to the fifth temperature. Also, in the sixth period of the second stage, the temperature of the first heating element is maintained at the fifth temperature or the temperature of the first heating element is increased from the fifth temperature to the seventh temperature. The fifth period and the sixth period are two periods obtained by partitioning the second stage in a second partitioning method. And the fifth period is shorter than the sixth period. And the fourth temperature is higher than the seventh temperature. In addition, in the process of the temperature of the first heating element decreasing from the second temperature to the fifth temperature in the fifth period, it may continue to decrease at the same decreasing rate, or first decrease slowly at the first decreasing rate and then rapidly decrease at the second decreasing rate.

[0060] In a specific embodiment, as shown in FIG. 5, the second stage (t1 to t2) may be partitioned into a fifth period (t1 to t22) and a sixth period (t22 to t2) by a second partitioning method. And the fifth period is shorter than the sixth period. Regarding the first heating element in the second stage, by performing heating control, the temperature in the fifth period is reduced from the second temperature T2 to the fifth temperature T5, and the temperature in the sixth period is maintained at the sixth temperature T6. Thereby, it becomes possible to avoid a situation in which the second part of the aerosol-forming substrate generates impurities or a burnt odor due to excessive high-temperature baking (this is also because when the first heating element is heated, the heat of the first part of the aerosol-forming substrate is transmitted to the second part).

[0061] In a specific embodiment, as shown in FIG. 6, similarly in this case, the second stage (t1 to t2) is partitioned into a fifth period (t1 to t22) and a sixth period (t22 to t2). And the fifth period is shorter than the sixth period. For the first heating element in the second stage, by performing heating control, the temperature in the fifth period is decreased from the second temperature T2 to the fifth temperature T5, and the temperature in the sixth period is increased from the fifth temperature T5 to the sixth temperature T6. Thereby, it becomes possible to avoid a situation where the second part of the aerosol generation substrate generates impurities and a burnt smell due to excessive high-temperature baking. Further, since the first heating element also raises the temperature in the sixth period, it is also possible to avoid a poor feeling in inhalation and a shortage of aerosol concentration due to insufficient baking of the second part of the aerosol generation substrate.

[0062] Furthermore, in an alternative embodiment, the first heating element may be heated and controlled by an electromagnetic heating method, and / or the second heating element may be heated and controlled by an electromagnetic heating method. And for the control of the two heating elements, an individual control method may be used, or an integrated control method may be used.

[0063] In a specific embodiment, when the first heating element is heated and controlled by an electromagnetic heating method, specifically, it includes the following.

[0064] By detecting the temperature of the first heating element in real time, a first temperature detection value is obtained.

[0065] Based on the first temperature detection value of the first heating element and the target temperature of each stage, a first control signal is output. The target temperature of the first stage of the first heating element is the first temperature and the second temperature, and the target temperature of the second stage is the fifth temperature.

[0066] Based on the first control signal, a corresponding first alternating magnetic field is generated. And the first heating element is located within the first alternating magnetic field.

[0067] Correspondingly, when the second heating element is heated and controlled by an electromagnetic heating method, specifically, it includes the following.

[0068] By detecting the temperature of the second heating element in real time, a second temperature detection value is obtained.

[0069] Based on the second temperature detection value of the second heating element and the target temperature at each stage, a second control signal is output. The target temperature of the first stage of the second heating element is the third temperature, and the target temperature of the second stage is the fourth temperature.

[0070] Based on the second control signal, a corresponding second alternating magnetic field is generated. And the second heating element is located within the second alternating magnetic field.

[0071] In the above embodiment, thermistors may be respectively provided on the surfaces of the first heating element and the second heating element, and the voltage values of the respective thermistors are detected to calculate the resistance values of the thermistors, thereby obtaining real-time temperature detection signals of the first heating element and the second heating element. In addition, two resonance circuits for generating the first alternating magnetic field and the second alternating magnetic field are further provided. The coils of the resonance circuit can generate an alternating electromagnetic field. And by arranging the two heating elements in the corresponding electromagnetic fields respectively, eddy currents are induced on the surfaces, and the heating elements generate heat. Further, the main control module controls the vibration intensity of the resonance circuit based on the detected temperature detection signals of the two parts by means of a software algorithm.

[0072] Naturally, the method by which the first heating element and the second heating element heat the aerosol-forming substrate may be infrared radiation heating, resistance heating, etc., and is not limited here.

[0073] Figure 7 is a logical structure diagram of Example 1 of the aerosol generating device in the present invention. The aerosol generating device 100 in this example includes a first heating element 21, a second heating element 22, a first control unit 11, and a second control unit 12. Further, the aerosol forming substrate includes a first part and a second part. And the first heating element 21 is used to heat the first part, and the second heating element 22 is used to heat the second part. For example, in a specific embodiment, as shown in FIG. 2, the aerosol forming substrate is in one complete unit. That is, the first part 31 and the second part 32 are not physically separated.

Also, the first heating element 21 and the second heating element 22 are each a cylindrical heating element, and each is covered on the first part 31 and the second part 32 of the aerosol forming substrate.

[0074] In the embodiment shown in FIG. 7, in the first stage, the first control unit 11 controls the heating of the first heating element 21 to raise the temperature of the first heating element 21 to a first temperature and then lower it to a second temperature. Also, in the second stage, by controlling the heating of the first heating element 21, the temperature of the first heating element 21 is lowered from the second temperature to the fifth temperature.

Also, in the fourth period of the second stage, the temperature of the second heating element is maintained at the fourth temperature, or the temperature of the second heating element is increased from the fourth temperature to a sixth temperature. The third period and the fourth period are two periods obtained by dividing the second stage in a first partitioning method. And the third period is shorter than the fourth period.

[0078] Furthermore, the first control unit 11 controls the heating of the first heating element to decrease the temperature of the first heating element from the second temperature to a fifth temperature in the fifth period of the second stage. Also, in the sixth period of the second stage, the temperature of the first heating element is maintained at the fifth temperature, or the temperature of the first heating element is increased from the fifth temperature to a seventh temperature. The fifth period and the sixth period are two periods obtained by dividing the second stage in a second partitioning method. And the fifth period is shorter than the sixth period. And the fourth temperature is higher than the seventh temperature.

Moreover, the difference between the second temperature and the first temperature is between 5 and 100 °C. Also, the third temperature is between 50 and 200 °C, and the fourth temperature is between 150 and 300 °C.

[0080] Furthermore, the first control unit 11 includes a first temperature detection module, a first main control module, and a first resonance module. The first temperature detection module is used to obtain a first temperature detection value by detecting the temperature of the first heating element in real time. The first main control module is used to output a first control signal based on the first temperature detection value and the target temperature at each stage. Note that the target temperature at the first stage is the first temperature and the second temperature, and the target temperature at the second stage is the fifth temperature. The first resonance module is used to generate a corresponding first alternating magnetic field based on the first control signal. And the first heating element is located within the first alternating magnetic field. The first resonance module is, for example, a first parallel resonance circuit.

[0081] Furthermore, the second control unit 12 includes a second temperature detection module, a second main control module, and a second resonance module. The second temperature detection module is used to obtain a second temperature detection value by detecting the temperature of the second heating element in real time. The second main control module is used to output a second control signal based on the second temperature detection value and the target temperature at each stage.

The second resonance module is used to generate a corresponding second alternating magnetic field based on the second control signal. And the second heating element is located within the second alternating magnetic field. The second resonance module is, for example, a second parallel resonance circuit.

[0082] Of course, in other embodiments, the first resonance module may be a first series resonance circuit, and the second resonance module may be a second series resonance circuit.

[0083] FIG. 8 is a circuit configuration diagram of the first control unit in the aerosol generator of the present invention. In the first control unit, a resistor R2 is connected in series with a thermistor RT1 provided on the surface of the first heating element to form a first temperature detection module. The first temperature detection module can obtain a first temperature detection value of the first heating element by measuring the voltage value of the thermistor RT1 and calculating the resistance value of the thermistor RT1. The detected first temperature detection value is transmitted to the first main control module. Further, an inductor coil L1, a capacitor C1, and a MOSFET Q1 form a single transistor parallel resonance circuit. During operation, the voltage of the battery (BAT+) is connected to the single transistor parallel resonance circuit, and an alternating current flows through the inductor coil L1. The alternating current generates an alternating electromagnetic field in the inductor coil L1. Since the first heating element is disposed in the electromagnetic field, the first heating element generates heat due to the hysteresis effect in the first heating element. Further, when the first heating element is made of a conductive material, eddy currents are induced on the surface of the first heating element, causing the first heating element to generate heat. The main control module controls the temperature of the first heating element to change according to a predetermined temperature curve by controlling the vibration intensity of the resonance circuit based on the first temperature detection value by means of a software algorithm.
