Please refer to Figure 1. Figure 1 is a cross-sectional view of an aerosol generating device 10 provided by an embodiment of the present application. The present application provides an aerosol generating device 10. The aerosol generating device 10 can heat an aerosol generating substrate 20. , so that the aerosol generating matrix 20 generates aerosol. The aerosol generating device 10 includes a heating element 11 , an air supply component 12 and a suction airway 13 .

The heating body 11 includes a heating cavity, and the inside of the heating cavity is used to place an aerosol-generating substrate so as to heat the aerosol-generating substrate when the heating body 11 is powered on. For heating the aerosol generating substrate 20 to generate 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connected to the outside, and the insertion port is used for the aerosol-generating substrate 20 to be inserted into or withdrawn from the heating chamber.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 matrix 20 includes at least a suction section and a matrix section. There is a grass-type substrate inside the substrate section, such as tobacco. When the aerosol-generating substrate 20 is disposed in the heating chamber, the heating component surrounds the peripheral side of the substrate section of the aerosol-generating substrate 20 so that the grass-type substrate generates aerosol. sol. When the aerosol generating matrix 20 is disposed in the heating chamber, the suction section is disposed outside the housing assembly, and the user can inhale the aerosol through the suction section.

In the aerosol generating device 10, the suction airway 13 is connected to the heating chamber, and the suction airway 13 is connected to the outside atmosphere. When the user inhales the aerosol-generating matrix 20, negative pressure will be generated inside the suction airway 13. Pressure, the airflow enters the suction airway 13 from the outside, enters the inside of the heating chamber from the suction airway 13, and finally flows into the inside of the aerosol-generating matrix 20. The airflow carries the atomized aerosol at the matrix section, and finally flows from the The suction section flows out for the user to smoke.

The air supply component 12 is communicated with the suction air channel 13. Usually, the air supply component 12 has a port, and the port of the air supply component 12 is communicated and connected with the suction air channel 13, so that the air supply component 12 can supply suction air to the air channel 13. In chapter 13, blow or pump air. The air supply component 12 may be an air pump or a water pump, for example.

Please refer to Figure 2. This application provides a control method for an aerosol generating device. The control method can be applied to the above-mentioned aerosol generating device 10. The control method includes:

Step S101: Obtain the start signal, control the heating element 11 to heat the aerosol-generating substrate 20 at a first preset temperature, and control the air supply component 12 to blow or extract air from the suction airway 13;

The start signal may be a signal generated when the user presses the switch case. The evaporation temperature of water is lower than the atomization temperature of aerosol. Therefore, in order to fully evaporate water in step S101, the first preset temperature is a temperature that can evaporate water but cannot atomize the aerosol-generating substrate 20 into an aerosol. The temperature, that is, the first preset temperature is higher than the evaporation temperature of water and lower than the atomization temperature of the aerosol. For example, the first preset temperature may be 100 degrees Celsius.

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 airway 13 , the water vapor can be discharged along the aerosol generating matrix 20 toward the cigarette mouthpiece. When the air supply component 12 exhausts the suction air channel 13, the water vapor can be discharged along the suction air channel 13 in a direction away from the cigarette mouthpiece.

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

Step S102: When the 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.

The second preset temperature is a temperature that can atomize the aerosol-generating substrate 20 into an aerosol, that is, the second preset temperature is higher than or equal to the atomization temperature of the aerosol.

The stop signal may include a signal that the air supply component's operating time reaches a preset operating time, and/or the stop signal may include a signal that obtains user input.

Since this application controls the heating element 11 to preheat the aerosol-generating substrate 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 preheats the aerosol-generating substrate 20 When the water is fully atomized into water vapor, use the air supply component 12 to blow or pump air into the suction airway 13, and the atomized water vapor can be discharged from the aerosol generating device 10, and then the temperature is raised to the second preset state. Assume that the temperature of the aerosol-generating matrix 20 is heated, and the water content of the aerosol generated at this time is at the lowest level, which can avoid the problem of the user's first puff of the aerosol having a high water vapor content and the aerosol burning the mouth.

In one embodiment, in step S101, when the start signal is obtained, the heating element 11 is controlled to heat the aerosol-generating substrate 20 at a first preset temperature, and at the same time, the air supply component 12 is controlled to blow air into the suction airway 13. Or exhausting, that is, in this embodiment, the heating to generate water vapor and the air supply component 12 to discharge the water vapor are performed at the same time. The preheating time of step S101 can be reduced, and the water vapor is discharged by the air supply component 12 when it is generated. It also prevents water vapor from accumulating in the aerosol generating device 10 and being difficult to discharge.

In one embodiment, in step S101, when acquiring the start signal, the heating element 11 is first controlled to heat the aerosol-generating substrate 20 at a first preset temperature and a first preset time. After the first preset time, The air supply component 12 is controlled to blow or pump air into the suction airway 13 . That is, in this embodiment, the water vapor is first generated by heating for a first preset time, and then the air supply component 12 discharges the water vapor.

In one embodiment, the air supply component is a pump body, which may be an air pump or a water pump, for example. Controlling the air supply component 12 to blow or pump air into the suction air channel 13 includes: controlling the air supply component 12 to blow or pump air into the suction air channel 13 with 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 rotation speed of the air supply component 12 , and/or the operating duration of the air supply component 12 . Different preset control parameters of the air supply component 12 for different models of aerosol generating substrates 20 can be set based on values recorded in experimental tests. Different models of aerosol-generating substrates 20 have different compositions and different water contents, and the air flow rate and duration of the drainage steam 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 may be control parameters that have been set before leaving the factory. Alternatively, before controlling the start of the air supply component 12, 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 control parameters of the air supply component 12 input by the user, whereby , users can control the water vapor content of the aerosol in the first puff according to their own preferences.

Since in the air pump, the volume of the compressed gas in the cylinder is fixed, the air flow rate of the air supply component 12 is proportional to the rotation speed of the air supply component 12. Therefore, the air flow rate of the air supply component 12 is proportional to the speed of the air supply component 12. There is a one-to-one correspondence between the number of revolutions or the rotation speed of the air supply component 12 , and the air flow rate can be represented by the number of revolutions or the rotation speed of the air supply component 12 .

Specifically, according to the preset control parameters of the air supply component 12, a pulse width modulation signal with a corresponding duty cycle is output to the air pump control circuit. The air pump control circuit is used to output a pulse width modulation signal to the air supply component according to the pulse width modulation signal (PWM, Pulse WidthModulation). 12 outputs working current to control the air flow rate of the air supply component 12 . The air pump is usually a motor air pump. It only needs to provide a suitable current to the motor air pump to drive the rotation of the electrode air pump.

When the air supply component 12 is started to operate, it will first operate with operating parameters corresponding to the preset control parameters of the air supply component 12 . The air flow flow of the air supply unit 12 can be monitored in real time during the operation of the air supply unit 12. If it is detected that the air flow flow deviates from the preset air flow flow, the output to the air pump control circuit can be adjusted through feedback adjustment. The duty cycle of the pulse width modulation signal is used to change the working current of the air supply component 12 when it is running, thereby adjusting the air flow rate of the air supply component 12, and finally matching the air flow rate of the air supply component 12 with the preset air flow rate to achieve The air supply component 12 is regulated.
