[0002] At present, the delivery form of smoke after the smoke generating device heats the atomized medium to generate aerosol is generally thermal convection diffusion and passive negative pressure suction.

[0024] In one embodiment, the main control unit is configured to, in response to a user's shutdown instruction, turn off the heating unit, turn on the micro-airflow unit, and turn off the micro-airflow unit after a fourth period of time.

[0045] The smoke generating device provided in the embodiment of the present application is used to heat the aerosol generating substrate to generate aerosol for the user to use. The heating method can be convection, conduction, radiation or a combination thereof. The form of the aerosol generating substrate can be liquid, gel, paste or solid, etc. When the aerosol generating substrate is solid, it can be a solid in the form of crushed, granulated, powdered, granular, strip or sheet. The aerosol generating substrate includes but is not limited to materials used for medical, health, health, and beauty purposes, for example, the aerosol generating substrate is a medicinal liquid, oil, or the aerosol generating substrate is a plant material, such as the roots, stems, leaves, flowers, buds, seeds, etc. of plants.

[0046] At present, the delivery form of smoke after the smoke generating device heats the atomized medium to generate aerosol is generally thermal convection diffusion and passive negative pressure suction. This form of smoke delivery depends on the consistency of the atomized medium and the user's smoking habits. The taste performance during the smoking process can only rely on temperature adjustment, and the consistency is difficult to grasp. Moreover, after users use it repeatedly, the temperature of the device is too high, and the experience is poor.

[0047] Based on the above problems, the present application provides a smoke generating device 11 to solve the above problems. Figure 1 , Figure 1 The schematic diagram of the structure of a smoke generating device 11 provided in an embodiment of the present application is shown. The smoke generating device 11 may include: a housing 10, a heating unit, a micro airflow unit 20 and a main control unit 30.

[0048] The housing 10 forms a receiving cavity 110, and the receiving cavity 110 has an insertion port 120, and the insertion port 120 is used for inserting the aerosol generating matrix. The embodiment of the present application does not limit the structure of the housing 10. For example, in this embodiment, the housing 10 can be a rectangular parallelepiped or a structure similar to a rectangular parallelepiped, and the projection of the housing 10 can be a rectangular structure, which can facilitate the allocation of the space inside the housing 10 to improve the space utilization rate inside the housing 10.

[0049] The receiving chamber 110 can be arranged inside the shell 10. The embodiment of the present application also does not limit the structure of the receiving chamber 110. For example, it can be a cylindrical shape as shown in this embodiment. Since most aerosol generating substrates are currently configured as cylindrical structures, the receiving chamber 110 is configured as a cylindrical structure so that it can be more suitable for the aerosol generating substrate.

[0050] The insertion port 120 may penetrate the surface of the housing 10 , and the insertion port 120 may connect the receiving cavity 110 with the outside, so as to facilitate the insertion of the aerosol generating substrate into the receiving cavity 110 .

[0051] The heating unit (not shown) can be used to heat the aerosol-generating substrate. The embodiment of the present application does not limit the specific location of the heating unit, and it can be set according to the actual heating form.

[0052] In a more specific embodiment, the heating unit can adopt a non-contact heating method. For example, the heating unit can be a combination of an electromagnetic coil and a magnet. In this case, the heating unit can be arranged on the outer surface of the receiving cavity 110. The heating unit can heat the receiving cavity 110, so that the air temperature in the receiving cavity 110 increases. When the aerosol generating matrix is ​​inserted into the receiving cavity 110, the aerosol generating matrix can be heated by the air and thus atomized. The use of a non-contact heating method can concentrate the heat in the receiving cavity 110, thereby improving the thermal efficiency of the heating unit. In addition, since the heating unit does not directly contact the aerosol generating matrix, it also prevents the aerosol generating matrix from being scorched, thereby avoiding the problem that the aerosol generating matrix has a poor taste after being heated and atomized, thereby affecting the user experience.

[0053] For another example, when contact heating is used, the heating unit can be a resistance needle. In this case, the heating unit can be arranged on the bottom surface of the receiving cavity 110, that is, the side away from the insertion port 120. After the aerosol generating substrate is inserted into the receiving cavity 110, it can further contact with the heating unit. For example, the heating unit can be inserted into the interior of the aerosol generating substrate. In this case, the heating unit can directly heat the aerosol generating substrate and atomize the aerosol generating substrate. The contact heating method can make the heat transfer efficiency of the heating unit higher. The aerosol generating substrate is directly in contact with the heating unit, which reduces the heat conduction of the intermediate medium, thereby improving the atomization efficiency of the aerosol generating substrate.

[0054] It can be understood that the heating unit can also be a combination of the above two structures. Specifically, in this embodiment, two heating units can be provided, one of which is in direct contact with the aerosol generating substrate, such as the aforementioned resistance needle, and the other heating unit is not in contact with the aerosol generating substrate, such as the aforementioned combination of the electromagnetic coil and the magnet. During use, the aerosol generating substrate can be directly inserted into the receiving chamber 110, so that the resistance needle is inserted into the interior of the aerosol generating substrate. The resistance needle directly heats the aerosol generating substrate. At the same time, the electromagnetic coil cooperates with the magnet to generate heat after being energized, and heats the air in the receiving chamber 110. The air in the receiving chamber 110 can further transfer heat to the aerosol generating substrate. In this embodiment, the heating unit in contact with the aerosol generating substrate can make the heating efficiency of the heating unit higher.

[0055] The micro-airflow unit 20 has an air inlet 210, which is connected to the outside. The micro-airflow unit 20 is used to provide active airflow into the receiving cavity 110. In this embodiment, the active airflow can be understood as the flow of gas caused by other factors other than the user. Specifically, in this embodiment, the micro-airflow unit 20 works, causing the gas flow to form an active airflow. Specifically, the micro-airflow unit 20 may include: an airflow cavity 220, a fan 230, and an airway 240.

[0056] The airflow cavity 220 may be in communication with the receiving cavity 110, so that the micro-airflow unit 20 provides active airflow to the receiving cavity 110, and the air inlet 210 may be disposed in the airflow cavity 220. In this embodiment, the airflow cavity 220 may be disposed on one side of the receiving cavity 110, so that the distance between the airflow cavity 220 and the receiving cavity 110 may be reduced, so that the active airflow provided by the micro-airflow unit 20 to the receiving cavity 110 can reach the receiving cavity 110 faster, thereby improving efficiency.

[0057] Specifically, the airflow chamber 220 and the receiving chamber 110 can be connected through the airway 240, that is, one end of the airway 240 can be connected to the airflow chamber 220, and the other end can be connected to the receiving chamber 110. The setting of the airway 240 can form a certain interval between the receiving chamber 110 and the airflow chamber 220, thereby preventing the heating unit in the receiving chamber 110 from being too close to the micro-airflow unit 20, causing damage to the fan 230 in the micro-airflow unit 20.

[0058] Furthermore, in the present embodiment, the airflow cavity 220 can be arranged in the shell 10 and located on one side of the receiving cavity 110, and the air inlet hole 210 can penetrate the surface of the shell 10, so that the airflow cavity 220 is connected with the outside air, and then the insertion port 120, the receiving cavity 110, the airflow cavity 220 and the air inlet hole 210 can be connected, so as to facilitate the airflow to flow in the insertion port 120, the receiving cavity 110, the airflow cavity 220 and the air inlet hole 210, and also facilitate the micro-airflow unit 20 to provide active airflow to the receiving cavity 110.

[0059] After the user inserts the aerosol generating matrix into the receiving chamber 110, the electronic atomization device 1 is started. Before the user inhales, the micro-airflow unit 20 can cooperate with the heating unit to keep the aerosol generating matrix in the receiving chamber 110 dry. Specifically, the heating unit can be turned on to heat the aerosol generating matrix in the receiving chamber 110, so that the residual moisture in the aerosol generating matrix forms high-temperature water vapor, and then the micro-airflow unit 20 is turned on to provide active airflow to blow out the above-mentioned high-temperature water vapor, thereby keeping the aerosol generating matrix in the receiving chamber 110 dry. After the moisture in the aerosol generating matrix is ​​discharged, the air intake can be increased and the preheating time can be shortened, so as to facilitate the subsequent atomization of the aerosol generating matrix.

[0060] When the user has finished heating the electronic atomization device 1, the micro-airflow unit 20 can be turned on to provide active airflow to blow out the aerosol remaining in the receiving chamber 110, thereby preventing the aerosol remaining in the receiving chamber 110 from condensing to form condensate, which adheres to the inner wall of the receiving chamber 110 and produces odor.

[0061] The fan 230 can be used to generate airflow in the airflow cavity 220 and blow it toward the air duct 240, thereby providing active airflow to the accommodating cavity. The embodiment of the present application does not limit the specific structure of the fan 230, for example, it can be an ordinary fan, etc. In one embodiment, the fan 230 can be a piezoelectric flat fan, which has the characteristics of small size, low working noise, high temperature resistance, low power consumption and good directionality.

[0062] For details, please refer to Figure 2 When the fan 230 adopts a piezoelectric planar fan, the fan 230 may include: a connecting portion 231 , a driving portion 232 and a fanning portion 233 .

[0063] The connecting portion 231 may be connected to the inner wall of the airflow cavity 220 . The embodiment of the present application does not limit the above connection method, and it may be, for example, bonding, clamping, etc., and the specific selection may be made according to actual conditions.

[0064] The driving part 232 can be connected to the connecting part 231 and electrically connected to the main control unit 30, and is used to drive the fan part 233 to fan to generate airflow. Specifically, the driving part 232 can be a piezoelectric ceramic, and the driving part 232 can convert electrical energy into mechanical energy through the inverse piezoelectric effect. Specifically, when the driving part 232 is powered on, the external electric field can cause the crystal volume of the driving part 232 to change, and then the fan part 233 can be driven to perform periodic motion, thereby generating airflow.

[0065] The fanning portion 233 may be connected to the driving portion 232 and extend toward the interior of the airflow cavity 220 . The fanning portion 233 may generate airflow into the airflow cavity 220 under the drive of the driving portion 232 .

[0066] The main control unit 30 is electrically connected to the heating unit and the micro-airflow unit 20. The main control unit 30 can also be arranged in the housing 10 and located on one side of the micro-airflow unit 20 and the heating unit, which can reduce the length of the wiring and is conducive to the miniaturization of the smoke generating device 1.

[0067] In a specific implementation, the main control unit 30 may be configured as:

[0068] In response to a control instruction from a user, turning on the heating unit;

[0069] Obtain the duration of the user's puff interval; when the puff interval duration is greater than or equal to the first duration, start the micro-airflow unit 20; when the puff signal is detected again or the startup duration of the micro-airflow unit 20 is greater than or equal to the second duration, the main control unit turns off the micro-airflow unit 20; when the startup duration of the heating unit is greater than or equal to the third duration, turn off the micro-airflow unit 20, and the third duration is greater than the second duration.

[0070] Specifically, the main control unit can be configured to turn on the heating unit in response to a control instruction from the user. The control instruction can be triggered by pressing a physical button on the smoke generating device 1, or by an airflow sensor, or by voice triggering through a voice receiving module in the smoke generating device 1, or by remote operation using a mobile terminal such as a mobile phone, etc., without limitation.

[0071] Exemplarily, in one embodiment, the smoke generating device 1 is provided with one or more physical buttons, each physical button may correspond to one or more preset instructions, and the control instruction may be triggered by the user by pressing the physical button provided on the smoke generating device 1. When the button is triggered, the preset instruction corresponding to the button is triggered and sent to the main control unit 30. After receiving the control instruction, the main control unit 30 controls the heating unit to execute the control instruction, thereby turning on the heating unit.

[0072] In another embodiment, the smoke generating device 1 may also be provided with a voice receiving module, which can obtain voice information sent by the user. Each voice information may correspond to one or more preset instructions. The control instruction can be triggered by the voice information. For example, "turn on" can be used as a voice message to turn on the heating unit. When the voice information is triggered, the preset instruction corresponding to the voice information is triggered and sent to the main control unit 30. After receiving the control instruction, the main control unit 30 controls the heating unit to execute the control instruction, thereby turning on the heating unit.

[0073] When the heating unit is turned on, the main control unit 30 can also be configured to obtain the user's puff interval duration. The user's puff interval duration refers to the time from the user taking a puff to the next puff. The user's puff interval duration can reflect whether the user is using the smoke generating device 1. If the user's puff interval duration is short, that is, the user takes two puffs in a short period of time, it indicates that the user is using the smoke generating device 1. If the user's puff interval duration is long, that is, after the user takes a puff, there is no next puff for a long time, it indicates that the user is not using the smoke generating device 1.

[0074] When the puff interval duration is greater than or equal to the first duration, the main control unit 30 is configured to start the micro-airflow unit 20. As mentioned above, the first duration can be the threshold used to judge the long and short puff intervals mentioned above. When the puff interval duration is greater than or equal to the first duration, it is determined that the user has suspended the use of the smoke generating device 1. For example, the first duration mentioned above can be 10 seconds, 15 seconds or 20 seconds, etc., which can be set according to the user's habits. Exemplarily, when the first duration is set to 10 seconds, if the user takes a second puff within 10 seconds after taking a puff, it indicates that the user continues to use the smoke generating device 1; if the user does not take a second puff until the 10th second after the first puff is completed, it indicates that the user has suspended the use of the smoke generating device 1 at this time. At this time, the main control unit 30 can be configured to start the micro-airflow unit 20. After the micro-airflow unit 20 is started, it can be used to blow out the aerosol remaining in the receiving chamber to prevent the aerosol from condensing and adhering to the receiving chamber 110, resulting in poor taste when the user puffs subsequently.

[0075] When the suction signal is detected again or the activation time length of the micro-airflow unit 20 is greater than or equal to the second time length, the main control unit 30 may be configured to turn off the micro-airflow unit 20 .

[0076] In one application scenario, when the suction signal is detected again, the main control unit 30 can be configured to turn off the micro-airflow unit 20. When the suction signal is detected again, it indicates that the user has used the smoke generating device 1 again. At this time, turning off the micro-airflow unit 20 can prevent the user from being affected by the active airflow during suction, affecting the user's suction experience.

[0077] In another application scenario, when the startup duration of the micro-airflow unit 20 is greater than or equal to the second duration, the main control unit 30 can be configured to shut down the micro-airflow unit 20. When the startup duration of the micro-airflow unit 20 is greater than or equal to the second duration, it indicates that the active airflow provided by the micro-airflow unit 20 has completely discharged the aerosol remaining in the receiving chamber 110. At this time, shutting down the micro-airflow unit 20 can achieve the effect of energy saving and avoid the waste of energy caused by the long-term opening of the micro-airflow unit 20. In the embodiment of the present application, the second duration can be 10 seconds, 15 seconds or 20 seconds, etc., which can be set according to the type of aerosol generating matrix selected by the user during use, and is not limited here. For example, when the second duration is set to 10 seconds, the micro-airflow unit 20 is started 10 seconds later, indicating that the active airflow provided by the micro-airflow unit 20 has completely discharged the aerosol remaining in the receiving chamber 110.

[0078] In a specific implementation, for example, this embodiment is described by taking the method of directly heating the aerosol generating substrate as an example, in which case the main control unit 30 can be configured as follows:

[0079] In response to a control instruction from a user, the heating unit is turned on; the on-time of the heating unit and the temperature of the heating unit are obtained; when the temperature of the heating unit is greater than or equal to a first temperature and the on-time of the heating unit is greater than or equal to a second time, the micro-airflow unit 20 is started; when the on-time of the heating unit is greater than or equal to a third time, the micro-airflow unit 20 is turned off, and the third time is greater than the second time.

[0080] Specifically, the main control unit 30 may be configured to turn on the heating unit 30 in response to a control instruction from the user. It should be noted that the heating unit here may be turned on before the user draws inhalation, that is, the heating unit may be turned on at this time to play a preheating role, so that the smoke generating device 1 can be at the same temperature when the aerosol generating substrate is subsequently heated, reducing the condensation and inconsistent taste caused by the cumulative generation of aerosol in the continuous heating scenario, thereby solving the problem of poor taste in subsequent inhalation caused by the continuous generation and condensation of aerosol when the user does not draw inhalation for a long time, and improving the user's inhalation experience.

[0081] After the heating unit 30 is turned on, the main control unit 30 can be configured to obtain the on-time of the heating unit and the temperature of the heating unit. The on-time of the heating unit and the temperature of the heating unit can reflect the preheating situation. Specifically, when the on-time of the heating unit reaches a certain threshold and the temperature of the heating unit reaches a certain threshold, it can be indicated that the heating unit has completed preheating the receiving chamber 110. It should be noted that in this embodiment, the two parameters of the on-time of the heating unit and the temperature of the heating unit are used to determine the preheating situation. Combining the above two parameters can more accurately reflect the preheating situation. In some other embodiments, the preheating situation can also be reflected only by the on-time of the heating unit or only by the temperature of the heating unit. Although using one parameter to reflect the preheating situation is more rough than using two parameters to reflect the preheating situation, using only one parameter to reflect the preheating situation can be faster.

[0082] When the temperature of the heating unit is greater than or equal to the first temperature, and the on-time of the heating unit is greater than or equal to the second time, the main control unit 30 is configured to start the micro-airflow unit 20. As mentioned above, the temperature of the heating unit and the on-time of the heating unit can be used to reflect the preheating situation. Specifically, when the temperature of the heating unit is greater than or equal to the first temperature, and the on-time of the heating unit is greater than or equal to the second time, it is determined that the preheating is completed. At this time, the micro-airflow unit 20 can be started to blow out the high-temperature water vapor in the receiving chamber 110 to prevent these high-temperature water vapors from affecting the taste of the user when inhaling the first aerosol. It should be noted that the above-mentioned first temperature and second time can be preset or user-defined, and there is no limitation here. For example, the first temperature can be 280 degrees or 290 degrees, etc., and the second duration can be 10 seconds, 15 seconds, 20 seconds, 30 seconds, etc., which can be set specifically according to the type of aerosol generating substrate used by the user. The embodiment of the present application is not limited. For example, when the first temperature is set to 280 degrees and the first duration is set to 10 seconds, that is, when the temperature of the heating unit reaches 280 degrees, and the opening time of the heating unit reaches 10 seconds, it indicates that preheating has been completed. As mentioned above, due to the influence of the environment, for example, in cold areas, it is possible that after the opening time of the heating unit reaches 10 seconds, the temperature of the heating unit does not reach 280 degrees, and the preheating is not completed at this time. Therefore, combining the above two parameters together can more accurately reflect the preheating situation.

[0083] It should be noted that, in some other implementations, whether preheating is completed may be determined only based on the temperature of the heating unit or the duration of the heating unit being turned on.

[0084] When the opening duration of the heating unit is greater than or equal to the third duration, the main control unit 30 is configured to close the micro-airflow unit 20, and the third duration is greater than the second duration. In the process of the micro-airflow unit 20 being turned on, the heating unit is still continuously heated, so that a relatively high temperature is maintained in the receiving chamber 110, and a constant temperature is maintained in the receiving chamber 110, so as to facilitate the aerosol generation matrix atomization to maintain consistency during the process, so that the taste of the aerosol is the same or close, so as to improve the user's inhalation experience. When the opening duration of the heating unit reaches a certain time, that is, the above-mentioned third duration, i.e., the preheating duration, it can be determined that the high-temperature water vapor in the aerosol generation matrix in the receiving chamber 110 has been completely blown out at this time, and the micro-airflow unit 20 can be turned off at this time. For example, the third duration can be 20 seconds, 30 seconds, etc., which can be specifically set according to actual conditions, and is not limited here. For example, when the opening time of the heating unit reaches 20 seconds, it indicates that the smoke generating device 1 has completed preheating and has completely discharged the high-temperature water vapor in the aerosol generating matrix in the receiving chamber 110, and the micro-airflow unit 20 can be closed at this time. It can be understood that the third time period is at least greater than the second time period, because the second time period indicates that the preheating is completed, and at this time, the high-temperature water vapor generated by the aerosol generating matrix will still remain in the receiving chamber 110, so additional time is required to discharge the remaining high-temperature water vapor to avoid scalding the user.

[0085] In another specific embodiment, for example, this embodiment is described by taking the method of indirectly heating the aerosol generating matrix as an example. At this time, the main control unit 30 can be configured to: turn on the heating unit in response to the user's control instruction; obtain the on-time of the heating unit and the temperature of the heating unit; when the temperature of the heating unit is greater than or equal to the second temperature, start the micro-airflow unit 20; when the on-time of the heating unit is greater than or equal to the third time, turn off the micro-airflow unit 20.

[0086] Specifically, the main control unit can be configured to turn on the heating unit in response to a control instruction from the user. The control instruction can be triggered by pressing a physical button on the smoke generating device 1, or by voice triggering through a voice receiving module in the smoke generating device 1, or by remote operation triggering using a mobile terminal such as a mobile phone, etc., without limitation. The specific implementation method can refer to the above-mentioned embodiment, which will not be described in detail here.

[0087] When the heating unit is turned on, the main control unit 30 can also be configured to obtain the opening time of the heating unit and the temperature of the heating unit. Since the indirect heating method of the aerosol generating substrate is adopted in this embodiment, the heating unit is not in direct contact with the aerosol generating substrate. There are other media between the heating unit and the aerosol generating substrate that absorb heat, which makes it difficult for the opening time of the heating unit to reflect the temperature when the aerosol generating substrate is inserted into the receiving chamber 110. Therefore, in this embodiment, it can be determined whether the preheating is completed only by the temperature of the heating unit. The specific implementation method can refer to the above-mentioned embodiment and will not be repeated here.

[0088] When the temperature of the heating unit is greater than or equal to the second temperature, the main control unit 30 can also be configured to start the micro airflow unit 20. The specific implementation can refer to the above. Similarly, in this implementation, the second temperature can refer to the first temperature in the above implementation, which will not be repeated here.

[0089] When the opening time of the heating unit is greater than or equal to the third time, the main control unit 30 can also be configured to turn off the micro airflow unit 20. The specific implementation can refer to the above. Similarly, in this implementation, the third time can refer to the third time in the above implementation, which will not be repeated here.

[0090] It should be noted that, in addition to the above two embodiments, the embodiment of the present application can also atomize the aerosol generating substrate by combining indirect heating and direct heating, and the main control unit 30 can be configured the same as when the aerosol generating substrate is indirectly heated. It can be understood that since two heating methods are used at the same time, that is, in this embodiment, the smoke generating device 1 has two heating units, so the time to determine whether the preheating is completed in this embodiment can be less than the time to determine whether the preheating is completed in the previous embodiment. For example, if the preheating time is 30 seconds in the previous embodiment, in this embodiment, the preheating time can be set to 20 seconds.

[0091] In one embodiment, the main control unit 30 may also be configured to determine the rotation speed of the micro-airflow unit 20 according to the duration of the suction interval, and start the micro-airflow unit 20 at the determined rotation speed.

[0092] Specifically, when the user has just taken a puff, the rotation speed of the micro-airflow unit 20 can be set to a low speed. As the user's puff interval becomes longer, the rotation speed of the micro-airflow unit 20 can be set to a high speed to discharge the aerosol remaining in the receiving chamber 110 more quickly.

[0093] In one embodiment, the main control unit 30 may also be configured to: in response to a user's shutdown instruction, turn off the heating unit, turn on the micro-airflow unit 20, and turn off the micro-airflow unit 20 after a fourth period of time.

[0094] The closing command here can be triggered by pressing a physical button set on the smoke generating device 1, or by voice triggering of a voice receiving module set in the smoke generating device 1, or by remote operation triggering using a mobile terminal such as a mobile phone, etc., and there is no limitation here.

[0095] When the main control unit 30 receives the shutdown command, it can directly turn off the heating unit and turn on the micro-airflow unit 20. The micro-airflow unit 20 can be used to discharge the aerosol remaining in the receiving chamber 110. Taking energy saving and environmental protection into consideration, after the micro-airflow unit 20 is turned on for a period of time, that is, after the fourth time, it is determined that the aerosol remaining in the receiving chamber 110 has been completely discharged. At this time, the micro-airflow unit 20 can be turned off.

[0096] In another embodiment, the main control unit 30 may be configured to: in response to a user's shutdown instruction, turn off the heating unit, turn on the micro-airflow unit 20, and turn off the micro-airflow unit 20 when the temperature of the heating unit drops to a third temperature.

[0097] That is to say, in this embodiment, it is also possible to determine whether the aerosol remaining in the receiving cavity 110 has been completely discharged by the temperature of the heating unit. After the heating unit is turned off, there will still be residual heat for a period of time. During this process, the temperature of the heating unit will slowly decrease. When the temperature of the heating unit decreases to the third temperature, it is determined that the aerosol remaining in the receiving cavity 110 has been completely discharged.

[0098] The above-mentioned smoke generating device 1 is provided with a micro-airflow unit 20, and uses the main control unit 30 to control the micro-airflow unit 20 to provide active airflow in the receiving chamber 110 in the shell 10. Before the user inhales, the main control unit 30 can control the heating unit to preheat the receiving chamber 110, and then heat the aerosol generating matrix inserted into the receiving chamber 110, and then control the micro-airflow unit 20 to blow out the high-temperature water vapor in the aerosol generating matrix, so that the receiving chamber 110 can be kept dry and the aerosol generating matrix can be kept dry, so that there is no interference from water vapor, which solves the problem that the user is easily affected by high-temperature water vapor when inhaling the first aerosol. The problem of scalding can be solved. At the same time, after the moisture in the aerosol generating matrix is ​​discharged, the air intake can be increased, the preheating time can be shortened, and the user experience can be improved. In addition, the temperature in the receiving chamber 110 can be kept consistent, and finally the atomization degree of the aerosol generating matrix by the smoke generating device 1 is made consistent, which is beneficial to ensure that the user has a consistent taste every time he inhales, and solves the problem that the aerosol continues to be generated and condensed when the user does not inhale for a long time, resulting in a poor taste in subsequent inhalation, which improves the user experience and can also be beneficial to the cleaning of the smoke generating device 1, reducing the odor left after the aerosol is condensed and attached to the receiving chamber 110.

[0099] See also Figure 3 and Figure 4 The present application also provides a method for controlling a smoke generating device, which may include the following steps:

[0100] S110: In response to a control instruction from a user, turning on the heating unit.

[0101] The control command can be triggered by pressing a physical button set on the smoke generating device, or by an airflow sensor, or by voice triggering through a voice receiving module set in the smoke generating device, or by remote operation using a mobile terminal such as a mobile phone, etc., without limitation here.

[0102] Exemplarily, in one embodiment, the smoke generating device is provided with one or more physical buttons, each physical button may correspond to one or more preset instructions, and the control instruction may be triggered by a user by pressing a physical button provided on the smoke generating device. When the button is triggered, the preset instruction corresponding to the button is triggered and sent to the main control unit. After receiving the control instruction, the main control unit controls the heating unit to execute the control instruction, thereby turning on the heating unit.

[0103] In another embodiment, the smoke generating device may also be provided with a voice receiving module, which can obtain voice information sent by the user. Each voice information may correspond to one or more preset instructions. The control instruction can be triggered by the voice information. For example, "turn on" can be used as a voice message to turn on the heating unit. When the voice information is triggered, the preset instruction corresponding to the voice information is triggered and sent to the main control unit. After receiving the control instruction, the main control unit controls the heating unit to execute the control instruction, thereby turning on the heating unit.

[0104] See also Figure 5 In one implementation, step S110 may further include:

[0105] S111: In response to a control instruction from a user, turning on the heating unit.

[0106] S112: Acquire the on-time of the heating unit and the temperature of the heating unit.

[0107] The on-time of the heating unit and the temperature of the heating unit can reflect the preheating situation. Specifically, when the on-time of the heating unit reaches a certain threshold and the temperature of the heating unit reaches a certain threshold, it can be indicated that the heating unit has completed preheating the receiving chamber 110. It should be noted that in this embodiment, the on-time of the heating unit and the temperature of the heating unit are used to determine the preheating situation. Combining the above two parameters can more accurately reflect the preheating situation. In some other embodiments, the preheating situation can also be reflected only by the on-time of the heating unit or only by the temperature of the heating unit. Although using one parameter to reflect the preheating situation is rougher than using two parameters to reflect the preheating situation, using only one parameter to reflect the preheating situation can be faster.

[0108] S113: When the temperature of the heating unit is greater than or equal to the first temperature, and the activation time of the heating unit is greater than or equal to the second time, the micro-airflow unit is activated.

[0109] As mentioned above, the temperature of the heating unit and the opening time of the heating unit can be used to reflect the preheating situation. Specifically, when the temperature of the heating unit is greater than or equal to the first temperature, and the opening time of the heating unit is greater than or equal to the second time, it is determined that the preheating has been completed. At this time, the micro-airflow unit 20 can be started to blow out the high-temperature water vapor in the receiving chamber 110 to prevent these high-temperature water vapors from affecting the taste of the user when inhaling the first aerosol. It should be noted that the above-mentioned first temperature and second time can be preset or user-defined, and are not limited here. For example, the first temperature can be 280 degrees or 290 degrees, etc., and the second time can be 10 seconds, 15 seconds, 20 seconds, 30 seconds, etc., which can be set according to the type of aerosol generation matrix used by the user. The embodiment of the present application is not limited. For example, when the first temperature is set to 280 degrees and the first time is set to 10 seconds, that is, when the temperature of the heating unit reaches 280 degrees, and the opening time of the heating unit reaches 10 seconds, it indicates that the preheating has been completed. As mentioned above, due to environmental influences, for example in extremely cold regions, the temperature of the heating unit may not reach 280 degrees after the heating unit is turned on for 10 seconds, and the preheating is not completed at this time. Therefore, combining the above two parameters together can more accurately reflect the preheating situation.

[0110] It should be noted that since it takes time for the heating unit to heat up, preheating can be achieved while the heating unit continues to heat up. That is to say, in some other embodiments, it can also be determined whether preheating has been completed based solely on the temperature of the heating unit or the duration of the heating unit being on.

[0111] S114: When the on time of the heating unit is greater than or equal to a third time, turning off the micro airflow unit, and the third time is greater than the second time.

[0112] During the process of opening the micro-airflow unit 20, the heating unit is still continuously heating, so that the temperature in the receiving chamber 110 is maintained at a high level, so that after the subsequent aerosol generating matrix is ​​inserted into the insertion chamber, the insertion chamber maintains a constant temperature, so as to facilitate the aerosol generating matrix atomization to maintain consistency during the process, so that the taste of the aerosol is the same or close, so as to improve the user's smoking experience. When the opening time of the heating unit reaches a certain time, that is, the third time, that is, the preheating time mentioned above, it can be determined that the high-temperature water vapor in the receiving chamber 110 has been completely blown out at this time. At this time, the micro-airflow unit 20 can be closed, and the aerosol generating matrix is ​​inserted into the receiving chamber 110 for atomization operation. For example, the third time can be 20 seconds, 30 seconds, etc., which can be set according to actual conditions, and is not limited here. For example, when the opening time of the heating unit reaches 20 seconds, it indicates that the smoke generating device 1 has completed preheating and has completely discharged the high-temperature water vapor in the receiving chamber 110, and the micro-airflow unit 20 can be closed at this time. It is understandable that the third time duration is at least greater than the second time duration. Since the second time duration indicates that preheating is completed, high-temperature water vapor will still remain in the receiving cavity at this time, so extra time is required to discharge the remaining high-temperature water vapor to avoid scalding the user.

[0113] See also Figure 6 In another implementation, step S110 may further include:

[0114] S115: Obtaining the on-time of the heating unit and the temperature of the heating unit.

[0115] The control command may be triggered by pressing a physical button on the smoke generating device, by an airflow sensor, by a voice receiving module in the smoke generating device, or by remote operation using a mobile terminal such as a mobile phone, etc., without limitation. The specific implementation method may refer to the above-mentioned embodiment, which will not be described in detail here.

[0116] When the heating unit is turned on, the main control unit can also be configured to obtain the opening time of the heating unit and the temperature of the heating unit. Since the indirect heating method of the aerosol generating substrate is adopted in this embodiment, the heating unit is not in direct contact with the aerosol generating substrate. There are other media between the heating unit and the aerosol generating substrate that absorb heat, which makes it difficult for the opening time of the heating unit to reflect the temperature when the aerosol generating substrate is inserted into the receiving cavity. Therefore, in this embodiment, it can be determined whether the preheating is completed only by the temperature of the heating unit. The specific implementation method can refer to the above-mentioned embodiment and will not be repeated here.

[0117] S116: When the temperature of the heating unit is greater than or equal to the second temperature, the micro airflow unit is started.

[0118] The specific implementation manner may refer to the above. Similarly, in this implementation manner, the second temperature may refer to the first temperature in the above implementation manner, which will not be described in detail here.

[0119] S117: When the on time of the heating unit is greater than or equal to the third time, the micro airflow unit is turned off.

[0120] The specific implementation method can refer to the above. Similarly, in this implementation method, the third time length can refer to the third time length in the above implementation method, which will not be repeated here.

[0121] S120: Obtain the duration of the user's puff interval.

[0122] The puff interval time of the user refers to the time from the user taking a puff to the next puff. The puff interval time of the user can reflect whether the user is using the smoke generating device. If the puff interval time of the user is short, that is, the user takes two puffs in a short period of time, it indicates that the user is using the smoke generating device. If the puff interval time of the user is long, that is, after the user takes a puff, there is no next puff for a long time, it indicates that the user is not using the smoke generating device.

[0123] S130: When the suction interval duration is greater than or equal to the first duration, start the micro airflow unit.

[0124] As mentioned above, the first duration can be the threshold used to judge long time and short time mentioned above. When the puff interval duration is greater than or equal to the first duration, it is determined that the user has suspended the use of the smoke generating device. For example, the above-mentioned first duration can be 10 seconds, 15 seconds or 20 seconds, etc., which can be set according to the user's habits. Exemplarily, when the first duration is set to 10 seconds, if the user takes a second puff within 10 seconds after taking a puff, it indicates that the user is continuously using the smoke generating device; if the user does not take a second puff until the 10th second after completing the first puff, it indicates that the user has suspended the use of the smoke generating device at this time. At this time, the main control unit can be configured to start the micro-airflow unit. After the micro-airflow unit is started, it can be used to blow out the aerosol remaining in the receiving chamber to prevent the aerosol from condensing and adhering to the receiving chamber, resulting in poor taste when the user puffs subsequently.

[0125] S150: When the suction signal is detected again or the activation time of the micro-airflow unit is greater than or equal to the second time, the micro-airflow unit is turned off.

[0126] In one application scenario, when the suction signal is detected again, the main control unit can be configured to turn off the micro-airflow unit. When the suction signal is detected again, it indicates that the user has used the smoke generating device again. At this time, turning off the micro-airflow unit can prevent the user from being affected by the active airflow during the suction, causing the user to be choked and affecting the user's suction experience.

[0127] In another application scenario, when the startup duration of the micro-airflow unit is greater than or equal to the second duration, the main control unit can be configured to shut down the micro-airflow unit. When the startup duration of the micro-airflow unit is greater than or equal to the second duration, it indicates that the active airflow provided by the micro-airflow unit has completely discharged the aerosol remaining in the receiving chamber. At this time, shutting down the micro-airflow unit can achieve energy-saving effects and avoid the waste of energy caused by the long-term opening of the micro-airflow unit. In the embodiment of the present application, the second duration can be 10 seconds, 15 seconds or 20 seconds, etc., which can be set according to the type of aerosol generating matrix selected by the user during use. There is no limitation here. For example, when the second duration is set to 10 seconds, the micro-airflow unit is started 10 seconds later, indicating that the active airflow provided by the micro-airflow unit has completely discharged the aerosol remaining in the receiving chamber.

[0128] Furthermore, in some embodiments, the control method of the smoke generating device may further include:

[0129] S140: Determine the rotation speed of the micro-airflow unit according to the duration of the suction interval, and start the micro-airflow unit at the determined rotation speed.

[0130] Specifically, when the user has just taken a puff, the rotation speed of the micro-airflow unit can be set to a low speed. As the time between the user's puffs becomes longer, the rotation speed of the micro-airflow unit can be set to a high speed to discharge the aerosol remaining in the receiving chamber more quickly.

[0131] Please refer again Figure 3 In some embodiments, the control method of the smoke generating device may further include:

[0132] S161: In response to a user's shutdown instruction, the heating unit is turned off, the micro-airflow unit is turned on, and the micro-airflow unit is turned off after a fourth period of time.

[0133] The closing command here can be triggered by pressing a physical button set on the smoke generating device, or by voice triggering of a voice receiving module set in the smoke generating device, or by remote operation triggering using a mobile terminal such as a mobile phone, etc., and there is no limitation here.

[0134] When the main control unit receives the shutdown command, it can directly shut down the heating unit and turn on the micro-airflow unit, and use the micro-airflow unit to discharge the aerosol remaining in the receiving chamber. Considering energy saving and environmental protection, after the micro-airflow unit is turned on for a period of time, that is, after the fourth time, it is determined that the aerosol remaining in the receiving chamber has been completely discharged, and the micro-airflow unit can be turned off at this time.

[0135] Please refer again Figure 4 In some other embodiments, the control method of the smoke generating device may further include:

[0136] S162: In response to a user's shutdown instruction, the heating unit is turned off, the micro-airflow unit is turned on, and the micro-airflow unit is turned off when the temperature of the heating unit drops to a third temperature.

[0137] That is to say, in this embodiment, it is also possible to determine whether the aerosol remaining in the receiving chamber 110 has been completely discharged by the temperature of the heating unit. Since there will be residual temperature for a period of time after the heating unit is turned off, the temperature of the heating unit will slowly decrease during this process. When the temperature of the heating unit decreases to the third temperature, it is determined that the aerosol remaining in the receiving chamber has been completely discharged.

[0138] The control method of the above-mentioned smoke generating device can keep the temperature in the receiving chamber consistent by selectively starting the micro-airflow unit, and finally makes the smoke generating device have a consistent degree of atomization of the aerosol generating matrix, which is beneficial to ensure that the taste of the user is consistent every time the user inhales, and solves the problem that the aerosol continues to be generated and condensed when the user does not inhale for a long time, resulting in poor taste in subsequent inhalation, thereby improving the user experience.

[0139] The technical features of the above-mentioned embodiments can be combined arbitrarily.
