[0035] The beneficial effects of the present invention are:

[0036] The present invention provides a heated cigarette smoking device, comprising a smoking device shell, the smoking device shell having a accommodating cavity for placing a smoking substrate, the heated cigarette smoking device also comprising a base, a heating module and a rotating module, the base being connected to the smoking device shell; the heating module extending into the accommodating cavity, and comprising a shell and a heating core, the heated cigarette smoking device having a heating cavity, the heating cavity being formed by a cavity in the shell and the base, the heating core being arranged inside the heating cavity, connected to the base, and used for generating heat, the shell being provided with a through hole assembly for gas and heat to pass through, so that the heat emitted by the heating core can enter the accommodating cavity through the heating cavity and the through hole assembly in turn, and heat the smoking substrate, that is, the heating module uses air as a heat transfer medium to transfer heat to the smoking substrate, which can increase the utilization rate of heat, increase the baking area of ​​the smoking substrate, and increase the amount of aerosol generated. The rotating module is connected to the shell and is used to drive the shell to rotate relative to the base, so as to separate the shell from the smoking substrate and prevent the smoking substrate from adhering to the shell after baking, so as to prevent it from blocking the through-hole component. In addition, by rotating the shell relative to the base, the position of the through-hole component relative to the smoking substrate can be changed, so that hot air can enter the accommodating cavity in different directions, bake and heat the smoking substrate at different positions, and make the smoking substrate at different positions evenly heated.

[0037] The present invention also provides a control method for heated cigarette smoking utensils. In the control method for heated cigarette smoking utensils implemented by the above-mentioned heated cigarette smoking utensils, it is determined that the heated cigarette smoking utensils are started; the rotation module is started to drive the shell to rotate relative to the base; it is determined that the user starts the puffing action; the rotation module is closed; it is determined that the user ends the puffing action; it is judged whether the cumulative rotation amount of the shell has reached a preset amount; if the cumulative rotation amount of the shell does not reach the preset amount, the rotation module is restarted and closed after the shell rotates the preset rotation amount relative to the base. Through the above steps, the shell can always be controlled to rotate relative to the base through the rotation module when the user does not perform the puffing action, so as to change the position of the through-hole component relative to the smoking substrate, and the smoking substrates at different positions are baked and heated. When it is determined that the user starts to puff, the rotation is stopped to prevent the user's experience from being affected. After determining that the user ends the puffing action, if the cumulative rotation amount of the shell does not reach the preset amount, the rotation module is restarted, and closed after the shell rotates the preset rotation amount relative to the base, and the user starts to determine that the smoking action continues to be heated. Therefore, every time the user takes a puff, the rotation module controls the shell to rotate, so as to heat the smoking substrate at different positions, so that the smoking substrate at different positions is evenly heated and the smoke is evenly released.

[0038] The present invention also provides another method for controlling heated cigarette smoking utensils. In the method for controlling heated cigarette smoking utensils implemented by the above-mentioned heated cigarette smoking utensils, it is determined that the heated cigarette smoking utensils are started; the rotation module is started, and is closed after the shell body rotates a preset rotation amount relative to the base; it is determined that the rotation module has been closed for a preset duration; it is determined whether the cumulative rotation amount of the shell body has reached a preset amount; if the cumulative rotation amount of the shell body has not reached the preset amount, the rotation module is returned to start, and is closed after the shell body rotates a preset rotation amount relative to the base. Through the above steps, the rotation module can be closed after driving the shell body to rotate a preset rotation amount relative to the base, so as to heat the smoking substrate that the through-hole component is facing at this time. Subsequently, after the rotation module has been closed for a preset duration, if the cumulative rotation amount of the shell body has not reached the preset amount, the rotation module is restarted, and is closed after the shell body rotates a preset rotation amount relative to the base, so as to adjust the position of the through-hole component so that it continues to heat the smoking substrates in other areas, so that the smoking substrates in different positions are evenly heated.

[0058] Embodiment 1

[0059] Heated cigarettes are a type of new tobacco product that uses electric heating to bake cigarettes at low temperatures, so that the cigarettes produce smoke without burning. Existing heated tobacco devices usually heat cigarettes by heat conduction, that is, the heating element is in direct contact with the smoke-generating substrate, and the heat of the heating element is conducted to the smoke-generating substrate to form an aerosol. The problem is that the amount of aerosol released before and after the heating process is unstable, and after the puff is finished, the high-temperature smoke-generating substrate may adhere to the heating element, which needs to be manually cleaned and removed.

[0060] In this regard, this embodiment provides a heated cigarette smoking device to solve the problems in the prior art that the aerosol release amount before and after the heating process is unstable and the high-temperature smoking matrix may adhere to the heating element, and can be used in the technical field of heated cigarette smoking devices.

[0061] Reference Figure 1-Figure 2The heated cigarette smoking device includes a smoking device shell, and the smoking device shell has a receiving cavity for placing a smoking substrate, and the smoking substrate is used to generate smoke or aerosol. The heated cigarette smoking device also includes a base 1, a heating module 2 and a rotating module 3. The base 1 is connected to the smoking device shell; the heating module 2 extends into the receiving cavity and includes a shell 21 and a heating core 22. The heated cigarette smoking device has a heating cavity 23, and the heating cavity 23 is formed by the shell 21 and the cavity in the base 1. The heating core 22 is arranged inside the heating cavity 23, connected to the base 1, and used to generate heat. The shell 21 is provided with a through-hole component 211 for gas and heat to pass through, so that the heat emitted by the heating core 22 can enter the receiving cavity through the heating cavity 23 and the through-hole component 211 in turn to heat the smoking substrate. That is to say, the heating module 2 uses air as a heat transfer medium to transfer heat to the smoking substrate, which can increase the utilization rate of heat, increase the baking area of ​​the smoking substrate, and increase the amount of aerosol generated. The rotating module 3 is connected to the shell 21 and is used to drive the shell 21 to rotate relative to the base 1, so that the shell 21 is separated from the smoking substrate, preventing the smoking substrate from adhering to the shell 21 after baking, and preventing it from blocking the through-hole component 211. In addition, by rotating the shell 21 relative to the base 1, the position of the through-hole component 211 relative to the smoking substrate can be changed, so that hot air enters the accommodating cavity along different directions, bakes and heats the smoking substrate at different positions, and makes the smoking substrate at different positions evenly heated.

[0062] In this embodiment, the heating core 22 is columnar and is disposed inside the housing 21 to maximize the use of the heat generated by the heating core 22. A heating circuit is disposed on the heating core 22 to generate heat. Specifically, the heating circuit is electrically connected to a power source and can generate heat when powered. Optionally, the heating circuit is arranged in a spiral along the side wall of the heating core 22 to increase the length of the heating core 22 as much as possible.

[0063] In another embodiment, the heating core 22 is tubular and has a plurality of air holes. In order to prevent the heating core 22 from affecting the rotation of the housing 21, the outer wall of the heating core 22 is gap-matched with the inner wall of the housing 21. By setting the heating core 22 to be tubular, the contact area between the heating core 22 and the gas can be increased, thereby improving the heat exchange efficiency between the heating core 22 and the gas.

[0064] In some other embodiments, the heating core 22 may be in other shapes, such as shaft-shaped, sheet-shaped, etc. In addition, the heating core 22 may also be disposed in a cavity within the base 1 to prevent the shell 21 from colliding with the heating core 22 during rotation.

[0065] Continue to refer to Figure 1-Figure 2The rotating module 3 includes a driving motor 31, a driving gear 32 and a driven gear 33. The driving gear 32 is connected to the output shaft of the driving motor 31, and the driven gear 33 is meshed with the driving gear 32. The housing 21 is fixedly disposed on the driven gear 33, so that the driving motor 31 can drive the driving gear 32 to rotate, and then drive the driven gear 33 to rotate, so as to drive the housing 21 to rotate synchronously.

[0066] In addition, the output shaft of the drive motor 31 may also be connected to the housing 21 via other transmission structures, such as a belt drive or a worm gear structure.

[0067] Continue to refer to Figure 1-Figure 2 The heated cigarette smoking device also includes a bearing 4, which has a first connecting end and a second connecting end. The first connecting end is connected to the driven gear 33, and the second connecting end is connected to the base 1, so that the driven gear 33 is stably connected to the base 1 and the friction between the two is reduced when relative rotation occurs.

[0068] Optionally, in some embodiments, the base 1 and the driven gear 33 may also be provided with ventilation holes to facilitate the flow of gas inside the base 1 .

[0069] Continue to refer to Figure 1-Figure 2 The through hole assembly 211 includes a plurality of through hole groups 212, and the through hole groups 212 include a plurality of through holes 213, and the plurality of through holes 213 are arranged at intervals along the axial direction of the housing 21, so that the through holes 213 in a through hole group 212 are arranged along the axial direction of the housing 21, so that the air flows out uniformly along the axial direction of the housing 21, so as to increase the uniformity of heating of the smoking substrate. Specifically, the arrangement of the through hole group 212 has the following optional schemes:

[0070] The first solution is that one through hole group 212 is provided, so that hot air is only allowed to flow to one side of the shell 21, and the shell 21 is driven to rotate by the rotating module 3, so that the hot air can evenly heat the smoking substrate in different directions.

[0071] The second solution is that there are two through hole groups 212, which are respectively located on both sides of the shell 21 and symmetrically arranged relative to the axis of the shell 21, so that hot air can flow to both sides of the shell 21, so that the hot air can heat the smoking substrate along different directions.

[0072] A third solution is that a plurality of through hole groups 212 are provided, and the plurality of through hole groups 212 are spaced apart along the circumferential direction of the shell 21, and the spacing between any two adjacent through hole groups 212 is equal, so that the plurality of through hole groups 212 are evenly distributed on the shell 21, so that the hot air can evenly heat the smoking substrate along different directions.

[0073] The fourth solution is that there are multiple through hole groups 212, and the multiple through hole groups 212 are all arranged on the same side of the shell 21, and the central angle corresponding to the two through hole groups 212 farthest apart does not exceed 90°, which is specifically 45° in this embodiment, and can also be 30°, 60°, 75° or 90°, etc. In this solution, hot air is only allowed to flow to one side of the shell 21, and the shell 21 can be driven to rotate by the rotating module 3, so that the hot air can also heat the smoking substrate uniformly in different directions.

[0074] Continue to refer to Figure 1-Figure 2 The base 1 has an airflow cavity 11, and the cavity between the inner wall of the shell 21 and the heating core 22 is connected to the airflow cavity 11, that is, the heating element 22 is located between the airflow cavity 11 and the through-hole component 211. The heated cigarette smoking device also includes an airflow generator 5. In this embodiment, the airflow generator 5 is arranged in the airflow cavity 12 to save space. In other embodiments, the airflow generator 5 can be arranged outside the airflow cavity 11. The airflow generator 5 is used to blow gas into the accommodating cavity. The gas flows through the heating element 22 and finally flows out from the through-hole component 211 and enters the accommodating cavity, thereby heating the smoking substrate. Such an arrangement can promote hot air to flow to the accommodating cavity and enhance the heating effect. In addition, since the gas flows out through the through-hole component 211, the smoking substrate can be prevented from blocking the through-hole component 211.

[0075] Continue to refer to Figure 1-Figure 2 The thermal conductivity of the shell 21 is lower than that of the heating core 22, that is, the thermal conductivity of the shell 21 is lower, while the thermal conductivity of the heating core 22 is higher, so that the heat can be quickly transferred from the heating core 22 to the surroundings, and most of the heat is transferred to the smoking substrate through the through-hole 211 component, rather than transferring the heat to the smoking substrate by heating the shell 21, so as to avoid the temperature of the part where the shell 21 is in direct contact with the smoking substrate being too high.

[0076] Continue to refer to Figure 1-Figure 2 The airflow cavity 11 includes a first cavity 111 for accommodating the airflow generator 5 and a second cavity 112 connected to the first cavity 111. The cavity between the inner wall of the housing 21 and the heating core 22 is connected to the second cavity 112. Along the flow direction of the gas, the cross-sectional area of ​​the second cavity 112 gradually decreases, thereby guiding the gas emitted by the airflow generator 5 and reducing the flow resistance of the gas. Optionally, the cavity wall of the second cavity 112 is in an inverted funnel shape as a whole.

[0077] Embodiment 2

[0078] The present embodiment provides a method for controlling a heated cigarette smoking utensil, which is implemented through the heated cigarette smoking utensil in the above-mentioned embodiment 1. Specifically, the method for controlling a heated cigarette smoking utensil can be used for the following schemes: applicable to the following schemes: one through hole group 212 is provided; two through hole groups 212 are provided, and the two through hole groups 212 are respectively located on both sides of the shell 21; or, a plurality of through hole groups 212 are provided, and the plurality of through hole groups 212 are all provided on the same side of the shell 21, and the central angle corresponding to the two through hole groups 212 that are farthest apart does not exceed 90°.

[0079] Reference Figure 3 The method for controlling the heated cigarette smoking utensil includes the following steps.

[0080] S100: Determine whether the heated cigarette smoking device is started.

[0081] S110 : starting the rotating module 3 to drive the housing 21 to rotate relative to the base 1 .

[0082] After the heating cigarette smoking device is started, the rotating module 3 is turned on to drive the housing 21 to rotate relative to the base 1, and at the same time, the housing 21 is separated from the smoking substrate to prevent the smoking substrate from being adhered to the housing 21 after being baked. At the same time, the position of the through-hole component 211 relative to the smoking substrate can be changed, so that hot air enters the accommodating cavity in different directions, and the smoking substrate at different positions is baked and heated.

[0083] Optionally, in step S110 , the rotating module 3 is started, and the airflow generator 5 is started, so that the airflow generator 5 is started synchronously to blow fresh air into the accommodating chamber through the airflow generator 5 .

[0084] S120: Determine whether the user starts the inhalation action.

[0085] Optionally, step S120 includes the following steps.

[0086] The actual air pressure inside the accommodating chamber is obtained, and the magnitude of the actual air pressure and the set air pressure is determined.

[0087] The actual air pressure inside the accommodating chamber can be obtained by a pressure sensor arranged in the accommodating chamber. The set air pressure is the normal air pressure that should be inside the accommodating chamber when the user does not inhale.

[0088] If the actual air pressure is less than the set air pressure, it means that the actual air pressure is less than the normal air pressure that should be inside the accommodating chamber when no inhalation is performed, indicating that the user has started to inhale, and it is determined that the user is performing the inhalation action. If the actual air pressure is not less than the set air pressure, it means that the actual air pressure is not less than the normal air pressure that should be inside the accommodating chamber when no inhalation is performed, indicating that the user has not started to inhale. At this time, the actual air pressure inside the accommodating chamber is repeatedly obtained, and the size of the actual air pressure and the set air pressure is judged again.

[0089] S130: Turn off the rotation module 3.

[0090] When it is determined that the user starts to inhale, the rotating module 3 is turned off to prevent the user's inhalation experience from being affected by the rotation of the shell 21 .

[0091] Optionally, in step S130, the rotating module 3 is turned off, and the airflow generator 5 is turned off, so that the airflow generator 5 is turned off synchronously when the user starts the inhalation action, so as to avoid the gas blown by the airflow generator 5 affecting the user's inhalation experience.

[0092] S140: Determine whether the user has finished the puffing action.

[0093] Optionally, step S140 includes the following steps.

[0094] The actual air pressure inside the accommodating chamber is obtained, and the magnitude of the actual air pressure and the set air pressure is determined.

[0095] If the actual air pressure is not less than the set air pressure, it means that the actual air pressure has returned to the normal air pressure that should be inside the receiving chamber when no inhalation is performed, indicating that the user is no longer performing the inhalation action, and thus it is determined that the user has ended the inhalation action. If the actual air pressure is less than the set air pressure, it means that the actual air pressure is still small, indicating that the user is still in the inhalation state, and at this time, the actual air pressure inside the receiving chamber is repeatedly obtained, and the size of the actual air pressure and the set air pressure is again determined.

[0096] S150: Determine whether the accumulated rotation amount of the housing 21 has reached a preset amount.

[0097] If the accumulated rotation amount of the housing 21 has not reached the preset amount, step S160 is executed. If the accumulated rotation amount of the housing 21 has reached the preset amount, step S170 is executed.

[0098] S160: Restart the rotation module 3, and close it after the housing 21 rotates a preset amount relative to the base 1, and return to step S120.

[0099] Through this step, the rotation amount of the shell 21 relative to the base 1 can be set to a set value, and the position of the through-hole component 211 on the shell 21 is also changed synchronously, and the smoking substrate in another area can be heated at this time.

[0100] The preset amount and the preset rotation amount can be preset as needed. The preset amount can be the number of rotations, and the angle of each rotation is the same. In addition, the preset amount can also be the angle of rotation, such as 360°, 720° or 1080°. The preset rotation amount generally refers to the angle of rotation, such as 30°, 45°, 60° or 90°, and can also be the rotation time of the housing 21 at the same rotation speed.

[0101] Optionally, in step S160, the rotation module 3 is restarted, and is turned off after the shell 21 rotates a preset amount relative to the base 1, and the airflow generator 5 is started at the same time, so that when the user ends the suction action and the rotation module 3 is restarted, the airflow generator 5 is started to continue to blow fresh air into the accommodating chamber.

[0102] S170: Restart the rotation module 3 and control the housing 21 to always rotate at a preset speed.

[0103] If the accumulated rotation amount of the shell 21 has reached the preset amount, it indicates that the accumulated rotation amount of the shell 21 has reached the requirement. At this time, there is no need to heat a specific area separately. Instead, the rotation module 3 is controlled to work all the time and drive the shell 21 to rotate at the preset speed all the time.

[0104] Optionally, the preset rotation speed for controlling the rotation of the housing 21 is smaller than the rotation speed of the housing 21 in step S110 and step S160 .

[0105] The control method for heating cigarette smoking utensils provided in this embodiment can always control the rotation of the shell 21 relative to the base 1 through the rotation module 3 when the user does not perform the inhalation action, so as to change the position of the through-hole component 211 relative to the smoking substrate, and bake and heat the smoking substrate at different positions. Stop the rotation when it is determined that the user starts to inhale, so as to prevent affecting the user's experience. After determining that the user has finished the inhalation action, if the cumulative rotation amount of the shell 21 has not reached the preset amount, restart the rotation module 3, and turn off after the shell 21 rotates the preset rotation amount relative to the base 1, and return to determine that the user has started the inhalation action, so as to continue to heat the smoking substrate in other areas. Therefore, every time the user inhales, the shell 21 is controlled to rotate through the rotation module 3 to heat the smoking substrate at different positions, so that the smoking substrate at different positions is evenly heated and the smoke is evenly released.

[0106] Embodiment 3

[0107] The present embodiment provides another method for controlling heated cigarette smoking articles, which is implemented through the heated cigarette smoking articles in the above-mentioned embodiment 1. Specifically, the method for controlling heated cigarette smoking articles can be used for the following schemes: applicable to the following schemes: one through hole group 212 is provided; two through hole groups 212 are provided, and the two through hole groups 212 are respectively located on both sides of the shell 21; or, a plurality of through hole groups 212 are provided, and the plurality of through hole groups 212 are all provided on the same side of the shell 21, and the central angle corresponding to the two through hole groups 212 that are farthest apart does not exceed 90°.

[0108] Reference Figure 4 The method for controlling the heated cigarette smoking device includes the following steps.

[0109] S200: Determine whether the heated cigarette smoking device is started.

[0110] Optionally, in step S200, the airflow generator 5 is started at the same time, so that after the heating cigarette smoking device is started, the airflow generator 5 is started to blow fresh air into the accommodating cavity.

[0111] S210 : After a preset duration, the rotation module 3 is started, and is turned off after the housing 21 rotates a preset amount relative to the base 1 .

[0112] When the heated cigarette smoking device is started, the heating module 2 is turned on simultaneously to heat the smoking substrate.

[0113] After the preset duration, this step enables the housing 21 to rotate relative to the base 1 to a set value, and the position of the through-hole component 211 on the housing 21 also changes synchronously, so that the smoking substrate in another area can be heated.

[0114] S220: Determine whether the accumulated rotation amount of the housing 21 has reached a preset amount.

[0115] If the accumulated rotation amount of the housing 21 has not reached the preset amount, the process returns to step S210. If the accumulated rotation amount of the housing has reached the preset amount, the process proceeds to step S230.

[0116] After the rotation module 3 has been closed for a preset duration and the accumulated rotation amount of the shell 21 has not reached the preset amount, the rotation module 3 is turned on again after the preset duration, so that the rotation amount of the shell 21 relative to the base 1 is a set value, and the position of the through-hole component 211 on the shell 21 is also changed synchronously, and the smoking substrate in another area can be heated at this time.

[0117] The preset amount and the preset rotation amount can be preset as needed. The preset amount can be the number of rotations, and the angle of each rotation is the same. In addition, the preset amount can also be the angle of rotation, such as 360°, 720° or 1080°. The preset rotation amount generally refers to the angle of rotation, such as 30°, 45°, 60° or 90°, and can also be the rotation time of the housing 21 at the same rotation speed.

[0118] S230: Restart the rotation module 3 and control the housing 21 to always rotate at a preset speed.

[0119] If the accumulated rotation amount of the shell has reached the preset amount, it indicates that the accumulated rotation amount of the shell 21 has reached the requirement. At this time, there is no need to heat a specific area separately. Instead, the rotation module 3 is controlled to work all the time and drive the shell 21 to rotate at the preset speed all the time.

[0120] Optionally, the preset rotation speed for controlling the rotation of the housing 21 is smaller than the rotation speed of the housing 21 in step S210.

[0121] The control method for heating cigarette smoking articles provided in this embodiment can make the rotating module 3 turn off after driving the housing 21 to rotate relative to the base 1 by a preset rotation amount, so as to heat the smoking substrate that the through-hole component 211 is facing at this time. Subsequently, after the rotating module 3 has been turned off for a preset duration, if the cumulative rotation amount of the housing 21 has not reached the preset amount, the rotating module 3 is restarted and turned off after the housing 21 rotates relative to the base 1 by a preset rotation amount, so as to adjust the position of the through-hole component 211 so that it continues to heat the smoking substrate in other areas, so that the smoking substrate at different positions is evenly heated.

[0122] Embodiment 4

[0123] This embodiment provides another method for controlling a heated cigarette smoking article, which is implemented by using the heated cigarette smoking article in the first embodiment above.

[0124] Reference Figure 5 The method for controlling a heated cigarette smoking device comprises the following steps.

[0125] S300: confirm that the heated cigarette smoking device is turned on, and turn on the heating module 2 and the rotating module 3.

[0126] S310: Control the switch or power of the airflow generator 5 so that the gas flow inside the accommodating chamber is the early gas flow, the middle gas flow and the late gas flow in sequence as the operation time of the heated cigarette smoking device increases, and the early gas flow is greater than the middle gas flow, and the late gas flow is greater than the middle gas flow.

[0127] The gas flow rate inside the accommodating chamber can be changed by controlling the switch or power of the airflow generator 5. Specifically, when the airflow generator 5 is turned on from off, or the power of the airflow generator 5 is increased, the gas flow rate at the output end of the airflow generator 5 increases, and the gas flow rate inside the accommodating chamber can be increased. When the airflow generator 5 is turned off from on, or the power of the airflow generator 5 is reduced, the gas flow rate at the output end of the airflow generator 5 decreases, and the gas flow rate inside the accommodating chamber can be reduced.

[0128] Through step S310, the gas flow rate inside the accommodating chamber can be controlled. Since the aerosol-generating substrate is heated unevenly in the early stage of the heated cigarette smoking device, the smoke output is small. By controlling the gas flow rate inside the accommodating chamber to increase the gas flow rate inside the accommodating chamber in the early stage of the heated cigarette smoking device, the smoke-generating substrate can be heated evenly and the smoke output can be increased. In the middle stage of the heated cigarette smoking device, after the smoke-generating substrate is heated evenly, the gas flow rate inside the accommodating chamber is reduced. In addition, as the smoke-generating substrate is baked, its effective substances are gradually consumed, and the amount of smoke generated by the smoke-generating substrate in the late stage of the heated cigarette smoking device will also decrease. In the late stage of the heated cigarette smoking device, the gas flow rate inside the accommodating chamber is increased again to avoid a reduction in the amount of smoke. Experiments show that increasing the gas flow rate inside the accommodating chamber in the early and late stages of the heated cigarette smoking device can heat the smoke-generating substrate evenly, make the smoke output more stable, and not easily produce undesirable substances.

[0129] Reference Figure 6 As one of the solutions, step S310 includes the following steps.

[0130] S3111: Turn on the airflow generator 5.

[0131] Optionally, in step S3111, the heating module 2 is simultaneously controlled to operate at a first power to heat the smoking substrate.

[0132] S3112: Determine that the airflow generator 5 has been operating for a first duration.

[0133] The first duration can be considered as the time before the start-up of the heated cigarette smoking device. During the first duration, the smoking substrate is heated unevenly.

[0134] Specifically, the first duration can be pre-set and stored in the controller 5. When the airflow generator 5 is turned on, the timer is turned on. When the first duration is reached, it can be confirmed that the airflow generator 5 has worked for the first duration.

[0135] In addition, since there may be certain differences in the start-up time of the airflow generator 5 and the heating module 2 in some heated cigarette smoking devices, the first duration can also be obtained based on the working time of the heating module 2. Specifically, when the heating module 2 has worked for the first preset time, it can be considered that the airflow generator 5 has worked for the first duration.

[0136] S3113: Reduce the power of the airflow generator 5.

[0137] Reducing the power of the airflow generator 5 can reduce the gas flow at its output end, and can reduce the gas flow inside the accommodating cavity, so as to adapt it to the characteristics of heating the cigarette smoking article to start the mid-term smoking substrate.

[0138] Optionally, in step S3113, the heating module 2 is controlled to work at a second power to heat the smoking substrate, and the second power is less than the first power. Since the hot air temperature will be reduced when the wind speed is high, in this embodiment, when the power of the airflow generator 5 is high, the power of the heating module 2 is also high, and when the power of the airflow generator 5 is low, the power of the heating module 2 is also low, so that the temperature in the accommodating chamber is stably maintained within a range.

[0139] S3114: Determine that the airflow generator 5 has been operating for a second duration, and the second duration is greater than the first duration.

[0140] The second duration can be considered as the early and middle time of starting the heated cigarette smoking device. During the first duration to the second duration, the heating condition of the smoke-generating matrix is ​​better, and after the second duration, the effective substances of the smoke-generating matrix are consumed and the smoke output is affected.

[0141] Specifically, the second duration can be pre-set and stored in the controller 5. When the airflow generator 5 is turned on, the timer is turned on. When the second duration is reached, it can be confirmed that the airflow generator 5 has worked for the second duration.

[0142] In addition, since there may be certain differences in the start-up time of the airflow generator 5 and the heating module 2 in some heated cigarette smoking devices, the second duration can also be obtained based on the working time of the heating module 2. Specifically, when the heating module 2 has worked for the second preset time, it can be considered that the airflow generator 5 has worked for the second duration.

[0143] S3115: Increase the power of the airflow generator 5.

[0144] Increasing the power of the airflow generator 5 can increase the gas flow at its output end, and can increase the gas flow inside the accommodating cavity, so as to adapt it to the characteristics of the late smoking substrate of the heated cigarette smoking device. In this embodiment, the change of the flow size of the output end of the airflow generator 5 over time is as follows: Figure 7 shown.

[0145] Optionally, in step S3115, the heating module 2 is controlled to operate at the first power at the same time, so that when the power of the airflow generator 5 is increased, the power of the heating module 2 continues to be increased to continue to keep the temperature in the accommodating cavity relatively stable.

[0146] Reference Figure 8 As another solution, step S310 includes the following steps.

[0147] S3121: Turn on the airflow generator 5.

[0148] Optionally, in step S3121, the heating module 2 is simultaneously controlled to operate at a first power to heat the smoking substrate.

[0149] S3122: Determine that the airflow generator 5 has been operating for a first duration.

[0150] The first duration can be considered as the time before the start-up of the heated cigarette smoking device. During the first duration, the smoking substrate is heated unevenly.

[0151] Specifically, the first duration can be pre-set and stored in the controller 5. When the airflow generator 5 is turned on, the timer is turned on. When the first duration is reached, it can be confirmed that the airflow generator 5 has worked for the first duration.

[0152] In addition, since there may be certain differences in the start-up time of the airflow generator 5 and the heating module 2 in some heated cigarette smoking devices, the first duration can also be obtained based on the working time of the heating module 2. Specifically, when the heating module 2 has worked for the first preset time, it can be considered that the airflow generator 5 has worked for the first duration.

[0153] S3123: Turn off airflow generator 5.

[0154] Turning off the airflow generator 5 can also reduce the gas flow inside the accommodating chamber so as to adapt it to the characteristics of heating the cigarette smoking article to start the mid-term smoking substrate.

[0155] Optionally, in step S3123, the heating module 2 is controlled to operate at the second power to heat the smoking substrate. Since the blowing of gas will reduce the temperature of the hot air, in this embodiment, when the generator 5 is turned on, the power of the heating module 2 is higher, and when the airflow generator 5 is turned off, the power of the heating module 2 is also lower, so that the temperature in the accommodating chamber is stably maintained within a range.

[0156] S3124: Determine that the airflow generator 5 has been operating for a second duration, and the second duration is greater than the first duration.

[0157] The second duration can be considered as the early and middle time of starting the heated cigarette smoking device. During the first duration to the second duration, the heating condition of the smoke-generating matrix is ​​better, and after the second duration, the effective substances of the smoke-generating matrix are consumed and the smoke output is affected.

[0158] Specifically, the second duration can be pre-set and stored in the controller 5. When the airflow generator 5 is turned on, the timer is turned on. When the second duration is reached, it can be confirmed that the airflow generator 5 has worked for the second duration.

[0159] In addition, since there may be certain differences in the start-up time of the airflow generator 5 and the heating module 2 in some heated cigarette smoking devices, the second duration can also be obtained based on the working time of the heating module 2. Specifically, when the heating module 2 has worked for the second preset time, it can be considered that the airflow generator 5 has worked for the second duration.

[0160] S3125: Restart the airflow generator 5.

[0161] Turning on the airflow generator 5 can also increase the gas flow rate inside the accommodating chamber to adapt it to the characteristics of heating the cigarette smoking device to start the late smoking substrate. In this embodiment, the flow rate at the output end of the airflow generator 5 changes with time as shown in FIG. Fig. 9 shown.

[0162] Optionally, in step S3125, the heating module 2 is controlled to operate at the first power at the same time, so that when the airflow generator 5 is turned on again, the power of the heating module 2 continues to be increased to continue to keep the temperature in the accommodating cavity relatively stable.
