Please refer to FIG. 4 , which is a flow chart of a control method for an atomizer provided by the first embodiment of the present application.

The method for controlling an atomizer provided by the first embodiment of the present application includes:

S1: In response to receiving the start atomization signal, the heating element 3 is controlled to heat the surrounding air with the first power, and the driving member 7 is controlled to run at the first speed, so that the air heated by the heating element 3 is in the heating channel 1 flow to preheat the heating channel 1; wherein, when the driving member 7 operates at the first speed, the aerosol-generating substrate does not enter the atomization chamber 6.

Specifically, the atomization start signal includes a suction signal, a touch signal or a press signal, etc., where the suction signal can be detected by an airflow sensor, that is, when the airflow sensor detects the user's action of starting to suction, the control circuit of the power supply component 200 It can be determined that the signal to start the atomizer 100 is received. The touch signal can be realized through a touch button. For example, after the control circuit of the power supply assembly 200 receives the touch button activated by the user's touch, it can determine that the atomization start signal has been received. The press signal is similar to the touch signal. The only difference is that the press signal is implemented through a mechanical button. That is, when the control circuit of the power component 200 receives the mechanical button pressed by the user, it can determine that the atomization start signal has been received. In addition, a pressure sensor may also be provided for detecting the pressing signal to determine the atomization start signal.

In one embodiment, the first power can be understood as lower than the power of the heating element 3 to preheat the surrounding air when the user is in the puffing state. The first speed is the operating speed of the driving member 7 matched with the first power. It should be noted that when the driving member 7 operates at the first speed, the heating channel 1 is only preheated without generating aerosol, that is, When the driving member 7 operates at the first speed, the aerosol-generating substrate does not enter the atomization chamber 6 for atomization. The surrounding air is heated by the heating element 3, so that the air heated by the heating element 3 flows in the heating channel 1, so that the heated air can pre-heat the heating channel 1. The heat causes the temperature of the heating channel 1 to increase to reduce condensation generated on the inner wall of the heating channel 1 during subsequent atomization of the aerosol-generating substrate.

S2: In response to preheating the heating channel 1 for the first time, control the driving member 7 to operate at a second speed to atomize the aerosol-generating substrate to form the first droplets 4 located in the atomization chamber 6, and control heating The body 3 is operated at a second power to heat the first droplets 4 to form an aerosol.

Specifically, in this embodiment, preheating the heating channel 1 is based on controlling a certain time, wherein the first time may be less than 0.3 seconds. When the time for the heating element 3 to preheat the heating channel 1 reaches the first time, the driving member 7 can be controlled to run at the second speed. The second speed can be understood as the operating speed of the driving member 7 during normal suction by the user. . In this embodiment, the second speed of the driving member 7 may be greater than the first speed. When the driving member 7 operates at the second speed, the driving efficiency of the warm air generated by the heating element 3 is higher. Moreover, when the driving member 7 operates at the second speed, the aerosol-generating matrix in the liquid storage chamber 5 is sprayed into the atomization chamber 6 through the nozzle 2 to form relatively large first liquid droplets 4 . At the same time, when the driving member 7 operates at the second speed, the heating element 3 is controlled to operate at the second power. The second power can be understood as the operating power of the heating element 3 during normal suction by the user. When the heating element 3 is heated at the second power, the heating element 3 can further atomize the relatively large first liquid droplets 4 in the atomization chamber 6 to form an aerosol that can be directly sucked by the user. Wherein, the aerosol includes second liquid droplets that are finer than the first liquid droplets 4 .

Optionally, in an embodiment, the first power may be less than the second power, for example, the first power may be 80-90% of the second power, so that the first power can only preheat the heating channel 1 and is not sufficient. To atomize the aerosol-generating matrix.

In another embodiment, the first power may also be greater than the second power. For example, the first power may be greater than 100% of the second power but less than 150% of the second power. This allows the heating element 3 to quickly preheat the heating channel 1 with the first power, thereby improving the preheating efficiency of the heating channel 1 .

Optionally, in an embodiment, the first power may also be equal to 80% to 150% of the second power, which is selected according to needs. It can be understood that when the first power is greater, the preheating time for the heating channel 1 is shorter and the heating efficiency is higher. For example, it only takes 0.3 seconds for effective preheating. This application is based on the general length and diameter range of the heating channel 1 and materials, by setting the first power equal to 80% to 150% of the second power, preheating can be completed within 0.3 seconds without affecting the user experience. If the preheating time is too long, the user will not be able to inhale aerosol for a long time during the inhalation process but only inhale air, and the user experience will become worse.

Alternatively, the first speed of the driving member 7 may be 1 ml/s-4 ml/s. When the driving member 7 operates at a low speed at the first speed, it lasts for a first time, for example, the heating channel 1 is preheated for 0.2 seconds. The inventor of the present application found through experiments that when the speed exceeds 4 ml/s, the aerosol-generating matrix in the liquid storage tank 5 is easily taken out, causing liquid leakage problems. If the first speed is less than 1 ml/s, the driving member 7 will push the warm gas to flow in the heating channel 1 very slowly, so that the heated gas has a poor preheating effect in the heating channel 1 . Therefore, this application adopts a first speed of 1ml/s-4ml/s, which can ensure the preheating efficiency of the heating channel 1 to the greatest extent, and at the same time, it will not cause the problem of aerosol being sucked into the atomization chamber 6 and causing liquid leakage.

Optionally, the second speed of the driving member 7 can be 5-10 ml/s. When the driving member 7 runs at a low speed at the first speed and preheats the heating channel 1 for 0.2 seconds, the control circuit of the power supply assembly 200 controls the driving. The component 7 starts to run at the second speed, and the driving component 7 drives the nozzle 2 to eject the aerosol-generating matrix from the liquid storage chamber 5 to form the first droplets 4 . At the same time, the heating element 3 is heated with the second power to further heat and atomize the first liquid droplets 4 to form an aerosol that can be sucked by the user. In other embodiments, the first speed can also be set to other numerical ranges, as long as the negative pressure in the atomization chamber 6 is not enough to suck the aerosol-generating matrix into the atomization chamber 6 when the driving member 7 starts to operate. Atomization is sufficient, and this application does not impose specific restrictions on this.

Please refer to FIG. 5 , which is a flow chart of a control method for an atomizer provided by the second embodiment of the present application.

This application also provides another atomizer control method for the power supply assembly 200 of the active liquid supply electronic atomization device 300. For the specific structures of the electronic atomization device 300 and the power supply assembly 200, please refer to the foregoing content. Again.

The control method of the atomizer provided by the second embodiment of the present application includes:

S3: In response to receiving the stop atomization signal, control the driving member 7 to run at the third speed for the third time, so that the aerosol in the heating channel 1 flows out; wherein, the driving member 7 runs at the third speed. During three-speed operation, the aerosol-generating matrix does not enter the atomization chamber 6.

Specifically, the stop atomization signal may include a stop puffing signal, a stop touching signal, a stop pressing signal, a touch signal again or a pressing signal again, etc. The stop puffing signal may be detected by the airflow sensor to determine whether the stop puffing signal is received. Suck signal. The stop touch signal can also be: for example, when the electronic atomization device 300 is set to touch the power component 200, it means that the user is smoking. Then when the user stops smoking and does not touch the power component 200, acceptance can be determined. A signal to the user to stop puffing. The stop pressing signal may be: for example, when the electronic atomization device 300 is configured to keep pressing a certain button of the power component 200 to indicate that the user is using the electronic atomization device 300 for atomization, then when the user stops pressing the button , it can be determined that it is accepted that the user stops using the electronic atomization device 300 for atomization. The touch signal again can be: for example, when the electronic atomization device 300 is set to touch the switch button of the power component 200 once, it means that the user is using the electronic atomization device 300 for atomization, then when the user touches the button again, that is, It can be determined that it is accepted that the user stops using the electronic atomization device 300 for atomization. The re-press signal may be: for example, when the electronic atomization device 300 is configured such that pressing the switch button of the power component 200 once indicates that the user starts to use the electronic atomization device 300 for atomization, then when the user presses the button again, It is determined that the user stops using the electronic atomization device 300 for atomization. Among them, the touch signal can be set through the touch button, and the press signal can be set through the mechanical button. It can be understood that in other embodiments, the receipt of a signal to stop atomization can also be expressed in other ways, and this application does not limit this.

At this time, the control circuit of the power supply assembly 200 controls the driver 7 to continue running at the third speed, for example, for a third time. The third time is subject to being able to bring all the aerosols remaining in the heating channel 1 out of the heating channel 1. For example, the third time may be less than 0.5 seconds. By continuing to control the operation of the driving member 7 after detecting the user's signal to stop smoking, the aerosol remaining in the heating channel 1 during suction can be brought out of the heating channel 1 through the driving member 7, and then the driving member 7 is controlled to stop. This prevents the aerosol remaining in the heating channel 1 from slowly condensing on the inner wall of the heating channel 1 to form condensate after the user stops smoking. This can prevent the condensate generated after multiple puffs from gathering together, causing the user to puff into the aerosol-generating matrix, which affects the user's puffing taste.

Optionally, the third speed of the driving member 7 can be 1ml/s-4ml/s. It can be understood that the third speed can be smaller than the operating speed of the driving member 7 during normal suction by the user, so that the heating channel 1 can be The aerosol remaining in the aerosol is brought out of the heating channel 1 without pumping the aerosol-generating matrix in the liquid storage tank 5 into the atomization chamber 6. It can also reduce the power consumption of the driving component 7 and increase the operating life of the power supply component 200.

S4: Control the driving part 7 to stop running.

Specifically, after the driving member 7 runs at the third speed for a third time, the driving member 7 can be controlled to stop running. The third time can be set as needed, and this application does not limit this. As above, when the user's signal to stop puffing (signal to stop atomization) is detected, the control circuit of the power supply assembly 200 controls the driver 7 to run at a third speed for a third time, for example, at a speed of 3ml/s for 0.3 seconds. In order to take the remaining aerosol in the heating channel 1 out of the heating channel 1, the third speed at this time should be set so that the aerosol-generating substrate will not continue to be sucked into the atomization chamber 6 for atomization. . That is, while the remaining aerosol in the heating channel 1 is taken out, new aerosol cannot be generated. This can not only prevent the residual aerosol from generating condensation liquid in the heating channel 1 and affect the user's suction taste, but also can Avoid wasting the aerosol-generating matrix, etc., and avoid adding more power consumption.

It should be noted that when the control circuit of the power supply assembly 200 controls the driving member 7 to run at the third speed for the third time, it also needs to control the heating element 3 to stop heating at the same time.

Specifically, when a signal to stop atomization is received, it means that the user has stopped smoking, and then the heating element 3 is no longer needed to continue heating the heating channel 1. That is, the heating element 3 can be controlled at this time. Stop heating. Controlling the heating element 3 to stop heating can, on the one hand, prevent the heating element 3 from continuing to heat the heating channel 1 to generate more aerosols, and on the other hand, it can also reduce energy consumption and waste.
