[0001] The present invention relates to the technical field of heat-not-burn aerosol generating devices, and in particular to an aerosol generating device, a control method thereof, and a computer-readable storage medium. Background Art

[0002] An aerosol-generating device is an electronic device used to heat and atomize an aerosol-generating substrate so that the aerosol-generating substrate generates an inhalable aerosol.

[0003] Since the initial water content of the aerosol generating matrix is ​​relatively high and the atomization temperature of water is lower than the temperature at which the aerosol is generated, after the aerosol generating device starts heating, the water will be fully atomized during the preheating stage of the aerosol generating matrix, resulting in a higher water vapor content in the aerosol inhaled by the user for the first time, and a poor taste. In addition, the water vapor liquefies into water in the mouth, which will be very hot, resulting in a poor puffing experience for the user. Summary of the Invention

[0004] The main technical problem solved by the present invention is the problem of high water vapor content when taking the first puff of an aerosol generating device.

[0005] To solve the above technical problems, the present application provides a control method for an aerosol generating device. The method is applied to the aerosol generating device, wherein the aerosol generating device includes a heating element, an air supply component, and an inhalation air duct. The heating element includes a heating chamber, and the heating chamber is used to dispose an aerosol generating substrate. When the heating element is energized, the aerosol generating substrate is heated to generate an aerosol. The inhalation air duct is connected to the heating chamber, and the air supply component is connected to the inhalation air duct. The control method includes:

[0006] Obtaining a start signal, controlling the heating element to heat the aerosol-generating matrix at a first preset temperature, and controlling the air supply component to blow or draw air into the suction airway;

[0007] A stop signal is obtained, the air supply component is controlled to stop working, and the heating element is controlled to heat the aerosol generating substrate at a second preset temperature, where the second preset temperature is higher than the first preset temperature.

[0008] In one embodiment, when the start signal is obtained, the heating element is controlled to heat the aerosol generating substrate at a first preset temperature, and at the same time, the air supply component is controlled to blow or draw air into the suction airway.

[0009] In one embodiment, when a start signal is obtained, the heating element is first controlled to heat the aerosol generating substrate at a first preset temperature and for a first preset time. After the first preset time, the air supply component is controlled to blow or draw air into the suction airway.

[0010] In one embodiment, controlling the air supply component to blow air or to exhaust air from the suction airway includes: controlling the air supply component to blow air or to exhaust air from the suction airway according to preset control parameters of the air supply component.

[0011] In one embodiment, the air supply component is a pump body, and the preset control parameters of the air supply component include the number of revolutions or rotation speed of the air supply component, and / or the working time of the air supply component.

[0012] In one embodiment, the stop signal includes a signal indicating that the working time of the air supply component reaches a preset working time, and / or the stop signal includes a signal indicating that a user input is obtained.

[0013] In one embodiment, the preset control parameters of the air supply component include the control parameters set before leaving the factory, or, before the control air supply component is started, the control parameters of the air supply component input by the user are obtained, and the preset control parameters of the air supply component include the control parameters of the air supply component input by the user.

[0014] In one embodiment, the first preset temperature is higher than the evaporation temperature of water and lower than the atomization temperature of the aerosol, and the second preset temperature is higher than or equal to the atomization temperature of the aerosol.

[0015] In order to solve the above technical problems, the present application also provides an aerosol generating device, including a memory and a processor, wherein at least one program is stored in the memory, and the processor implements the control method of the aerosol generating device of any of the above embodiments by loading and executing at least one program.

[0016] In order to solve the above technical problems, the present application also provides a computer-readable storage medium, on which a program is stored. The program can be executed by a processor to implement the control method of the aerosol generating device of any of the above embodiments.

[0017] The control method of an aerosol generating device provided in the present application is applied to the aerosol generating device, which includes a heating element, an air supply component and an intake air duct. The heating element includes a heating chamber, which is used to set an aerosol generating substrate to heat the aerosol generating substrate when the heating element is energized to generate an aerosol. The intake air duct is connected to the heating chamber, and the air supply component is connected to the intake air duct. The control method includes: obtaining a start signal, controlling the heating element to heat the aerosol generating substrate at a first preset temperature, and controlling the air supply component to blow or exhaust air into the intake air duct; obtaining a stop signal, controlling the air supply component to stop working, and controlling the heating element to heat the aerosol generating substrate at a second preset temperature, where the second preset temperature is higher than the first preset temperature. Since the present application controls the heating element to preheat the aerosol generating substrate at a lower first preset temperature, the first preset temperature can be a temperature at which water vapor is generated but aerosol is not generated, so that the heating element can fully atomize the water into water vapor in advance, and the air supply component is used to blow or exhaust air into the suction airway, so that the atomized water vapor can be discharged from the aerosol generating device, and then the temperature is increased to heat the aerosol generating substrate at a second preset temperature. The water content of the aerosol generated at this time can be reduced, which can avoid the problem of high water vapor content in the aerosol taken by the user in the first puff and the problem of the aerosol being hot to the mouth.

References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0024] Please refer to Figure 1, which is a cross-sectional view of an aerosol-generating device 10 provided in one embodiment of the present application. The present application provides an aerosol-generating device 10 capable of heating an aerosol-generating substrate 20 to generate an aerosol. The aerosol-generating device 10 includes a heating element 11, an air supply component 12, and an air intake passage 13.

[0025] The heating element 11 includes a heating chamber, the interior of which is used to set an aerosol generating substrate to heat the aerosol generating substrate when the heating element 11 is powered on. It is used to heat the aerosol generating substrate 20 to generate an aerosol. The heating chamber has an insertion port connected to the outside, and the insertion port is used for the aerosol generating substrate 20 to be inserted into or withdrawn from the heating chamber. The aerosol generating substrate 20 includes at least a suction section and a substrate section. The interior of the substrate section has a grass-like substrate, such as tobacco. When the aerosol generating substrate 20 is set in the heating chamber, the heating component surrounds the circumference of the substrate section of the aerosol generating substrate 20 so that the grass-like substrate generates an aerosol. When the aerosol generating substrate 20 is set in the heating chamber, the suction section is set outside the shell assembly, and the user can inhale the aerosol by inhaling the suction section.

[0026] In the aerosol generating device 10, the suction air duct 13 is connected to the heating chamber, and the suction air duct 13 is connected to the outside atmosphere. When the user inhales the aerosol generating matrix 20, a negative pressure is generated inside the suction air duct 13. The airflow enters the suction air duct 13 from the outside, and enters the interior of the heating chamber from the suction air duct 13, and finally flows into the interior of the aerosol generating matrix 20. The airflow carries the atomized aerosol at the matrix section and finally flows out from the suction section for the user to inhale.

[0027] The air supply component 12 is in communication with the suction passage 13. Typically, the air supply component 12 has a port that is in communication with and connected to the suction passage 13 so that the air supply component 12 can blow air into or draw air from the suction passage 13. The air supply component 12 can be, for example, an air pump or a water pump.

[0028] Referring to FIG. 2 , the present application provides a control method for an aerosol generating device. The control method can be applied to the aerosol generating device 10 described above. The control method includes:

[0029] Step S101: obtaining a start signal, controlling the heating element 11 to heat the aerosol generating matrix 20 at a first preset temperature, and controlling the air supply component 12 to blow or draw air into the suction air passage 13;

[0030] The activation signal may be a signal generated when a user presses a switch. The evaporation temperature of water is lower than the atomization temperature of the aerosol. Therefore, to fully evaporate the water in step S101, the first preset temperature is a temperature that allows the water to evaporate but does not allow the aerosol-generating substrate 20 to be atomized into an aerosol. That is, the first preset temperature is higher than the evaporation temperature of water but lower than the aerosol atomization temperature. For example, the first preset temperature may be 100 degrees Celsius.

[0031] In step S101, after controlling the heating element 11 to heat the aerosol at a first preset temperature, the water vapor in the aerosol generating matrix 20 can be gradually evaporated. When the air supply component 12 blows air into the suction air duct 13, the water vapor can be discharged along the aerosol generating matrix 20 toward the mouthpiece. When the air supply component 12 draws air into the suction air duct 13, the water vapor can be discharged along the suction air duct 13 in a direction away from the mouthpiece.

[0032] In step S101 , while the water vapor is discharged, the aerosol generating substrate 20 is also preheated.

[0033] Step S102: when a stop signal is obtained, the air supply component 12 is controlled to stop working, and the heating element 11 is controlled to heat the aerosol generating substrate 20 at a second preset temperature, which is higher than the first preset temperature.

[0034] The second preset temperature is a temperature at which the aerosol-generating substrate 20 can be atomized into an aerosol, that is, the second preset temperature is higher than or equal to the atomization temperature of the aerosol.

[0035] The stop signal may include a signal indicating that the working time of the air supply component reaches a preset working time, and / or the stop signal includes a signal for obtaining user input.

[0036] Since the present application controls the heating element 11 to preheat the aerosol generating matrix 20 at a lower first preset temperature, the first preset temperature can be a temperature at which water vapor is generated but aerosol is not generated, so that the heating element can fully atomize the water into water vapor in advance, and the air supply component 12 is used to blow or exhaust air into the suction air duct 13, so that the atomized water vapor can be discharged from the aerosol generating device 10, and then the temperature is increased to heat the aerosol generating matrix 20 at a second preset temperature. The water content of the aerosol generated at this time can be reduced, which can avoid the problem of high water vapor content in the aerosol taken by the user in the first puff and the problem of the aerosol being hot to the mouth.

[0037] In one embodiment, in step S101, when the start signal is obtained, the heating element 11 is controlled to heat the aerosol generating matrix 20 at a first preset temperature, and at the same time, the air supply component 12 is controlled to blow or exhaust air into the suction air duct 13. That is, in this embodiment, heating to generate water vapor and the air supply component 12 discharging water vapor are performed simultaneously, which can reduce the preheating time of step S101. The water vapor is discharged by the air supply component 12 when it is generated, and it also prevents the water vapor from accumulating in the aerosol generating device 10 and being difficult to discharge.

[0038] In one embodiment, in step S101, upon receiving a start signal, the heating element 11 is first controlled to heat the aerosol-generating substrate 20 at a first preset temperature and for a first preset time. After the first preset time, the air supply component 12 is controlled to blow or draw air into the suction passage 13. In other words, in this embodiment, water vapor is first generated by heating for the first preset time, and then the water vapor is discharged by the air supply component 12.

[0039] In one embodiment, the air supply component is a pump body, for example, it can be an air pump or a water pump. Controlling the air supply component 12 to blow or exhaust the suction air duct 13 includes: controlling the air supply component 12 to blow or exhaust the suction air duct 13 with the preset control parameters of the air supply component 12. For example, the preset control parameters of the air supply component 12 include the number of revolutions or rotational speed of the air supply component 12, and / or the working time of the air supply component 12. Different preset control parameters of the air supply component 12 for different types of aerosol generating matrices 20 can be set according to the values ​​recorded in the experimental test. Different types of aerosol generating matrices 20 have different compositions and different water contents, and the air flow rate and duration of the water vapor required to be controlled by the air supply component 12 are also different. That is, the preset control parameters of the air supply component 12 can be control parameters set before leaving the factory. Alternatively, before controlling the air supply component 12 to start, the control parameters of the air supply component 12 input by the user are obtained. The preset control parameters of the air supply component 12 may also include the control parameters of the air supply component 12 input by the user, thereby allowing the user to control the water vapor content of the aerosol inhaled in the first puff according to his or her preferences.

[0040] Since in the air pump, the volume of the compressed gas in the cylinder is fixed, the size of the air flow rate of the air supply component 12 is proportional to the rotational speed of the air supply component 12. Therefore, the size of the air flow rate of the air supply component 12 is one-to-one corresponding to the number of revolutions or rotational speed of the air supply component 12, and the air flow rate can be characterized by the number of revolutions or rotational speed of the air supply component 12.

[0041] Specifically, a pulse width modulation signal with a corresponding duty cycle is output to the air pump control circuit based on preset control parameters of the air supply component 12. The air pump control circuit is configured to output an operating current to the air supply component 12 based on the pulse width modulation signal (PWM) to control the air flow rate of the air supply component 12. The air pump is typically an electric motor air pump, and the electrode air pump can be driven to rotate by simply providing the electric motor air pump with a suitable current.

[0042] When the air supply component 12 starts operating, it will first operate with operating parameters corresponding to the preset control parameters of the air supply component 12. The air flow rate of the air supply component 12 can be monitored in real time during the operation of the air supply component 12. If the air flow rate is detected to deviate from the preset air flow rate, the duty cycle of the pulse width modulation signal output to the air pump control circuit can be adjusted through feedback regulation to change the operating current of the air supply component 12 during operation, thereby adjusting the air flow rate of the air supply component 12. Ultimately, the air flow rate of the air supply component 12 is matched with the preset air flow rate, thereby achieving regulation of the air supply component 12.

[0043] As shown in FIG3 , the present application also provides an aerosol generating device 10 , comprising a memory 30 and a processor 40 . The memory 30 stores at least one program, and the processor 40 implements the control method of the aerosol generating device of any of the above-mentioned embodiments by loading and executing at least one program.

[0044] The present application also provides a computer-readable storage medium, on which a program is stored, and the program can be executed by a processor to implement the control method of the aerosol generating device in any of the above embodiments. It will be understood by those skilled in the art that all or part of the functions of the various methods in the above embodiments can be implemented by hardware or by computer programs.
