FIG. 1 is a schematic diagram of an electronic atomization apparatus according to an example of this application.
As shown in FIG. 1, the electronic atomization apparatus 100 includes an atomizer 10 (first part) and a power supply assembly 20 (second part), where the atomizer 10 and the power supply assembly 20 are integrally formed. In another example, it is feasible that the atomizer 10 is detachable connected to the power supply assembly 20.
The atomizer 10 includes a liquid storage cavity (not shown) configured to store an aerosol-forming substrate and an atomization assembly 11, where under an action of power provided by the power supply assembly 20, the atomization assembly 11 atomizes the aerosol-forming substrate to form an inhalable aerosol.
The aerosol-forming substrate is a liquid aerosol-forming substrate (that is, a liquid substrate).
The atomization assembly 11 includes a heating element to heat the liquid aerosol-forming substrate to form the inhalable aerosol. The heating element may be a resistive heating element, an electromagnetic induction heating element, or an infrared radiation heating element. In another example, the atomization assembly 11 includes an ultrasonic atomization sheet configured to generate high-frequency oscillation to ultrasonically atomize the liquid aerosol-forming substrate to form the inhalable aerosol.
The atomization assembly 11 further includes a liquid transmission unit. The liquid transmission unit may be, for example, a cotton fiber, a metal fiber, a ceramic fiber, a glass fiber, or a porous ceramic, which can transmit the liquid aerosol-forming substrate stored in the liquid storage cavity to the heating element or the ultrasonic atomization sheet through a capillary effect.
The power supply assembly 20 includes a battery cell 21 and a circuit 22.
The battery cell 21 provides power for operating the electronic atomization apparatus 100. The battery cell 21 may be a rechargeable battery cell or a disposable battery cell.
The circuit 22 can control overall operations of the electronic atomization apparatus 100. The circuit 22 not only controls operations of the battery cell 21 and the atomization assembly 11, but also controls operations of other elements in the electronic atomization apparatus 100.
The air outlet 12 is provided at an upper end of the electronic atomization apparatus 100, the air inlet 23 is provided at a lower end of the electronic atomization apparatus 100, and the airflow channel R1 (shown by a dotted arrow in the figure) extends from the air inlet 23 to the air outlet 12. Air flows into the airflow channel R1 through the air inlet 12 and flows out from the air outlet 23 after flowing through the atomization assembly 11. Positions of the air inlet 23 and the air outlet 12 are not limited to the manner shown in FIG. 1, and in another example, both the air inlet 23 and the air outlet 12 may be provided on the atomizer 10.
In a preferred implementation, the atomization assembly 11 defines a partial surface of the airflow channel R1. For example, an inner hollow portion of a tubular atomization assembly 11 defines a part of the airflow channel R1; or a surface of a plate-like atomization assembly 11 defines a part of the airflow channel R1.
A sensor 24 is configured to sense an airflow change in the airflow channel R1 to output a feature value. The feature value includes a feature value used for representing air pressure, an air pressure change, a flow, or a flow change, and the feature value may be an electrical signal such as a voltage signal, a resistance signal, or a capacitance signal. The sensor 24 may be arranged in the airflow channel R1 or may be in fluid communication with the airflow channel R1. In a preferred implementation, the sensor 24 is arranged in the power supply assembly and is located upstream of the atomization assembly 11 along an airflow direction. Preferably, the sensor 24 is an air pressure sensor.
FIG. 2 is a schematic diagram of a control method for an electronic atomization apparatus according to an example of this application, and the method is applied to a controller (not shown). The controller is arranged in the power supply assembly, and the controller may be a part of the circuit 22 or may be independent of the circuit 22. In a preferred implementation, the controller includes a microcontroller unit (MCU).
As shown in FIG. 2, the control method for an electronic atomization apparatus includes:

Step S11. Obtaining the feature value outputted by the sensor.
Step S12. Controlling the electronic atomization apparatus to be in an unlocked state according to a comparison result of the feature value outputted by the sensor or a parameter value derived from the feature value and a preset threshold.

When the electronic atomization apparatus 100 is in a locked state, even if an inhalation action or an inhalation instruction from a user is detected, the electronic atomization apparatus 100 cannot start atomization to protect children.
When the electronic atomization apparatus 100 is in the unlocked state, once the inhalation action or the inhalation instruction from the user is detected, the electronic atomization apparatus can normally start up the atomization assembly 11 for atomization.
For whether the electronic atomization apparatus 100 is inhaled, a microphone or an airflow sensor similar to a microphone is generally arranged in the electronic atomization apparatus to detect the airflow change in the airflow channel, so as to determine whether the electronic atomization apparatus is inhaled. Certainly, this application is not limited to this situation, and for example, a button manner is also feasible.
In Step S11, an I/O interface of the controller may be directly electrically connected to the sensor 24, and the feature value outputted by the sensor 24 may be obtained by opening the I/O interface.
In a preferred implementation, whether the electronic atomization apparatus is inhaled is detected; and
the feature value outputted by the sensor 24 is obtained in a case that the electronic atomization apparatus is inhaled.
In this implementation, whether the electronic atomization apparatus 100 is inhaled is detected, and the feature value outputted by the sensor 24 is obtained by opening the I/O interface of the controller, or the sensor 24 is controlled to be powered to obtain the feature value outputted by the sensor 24. In this way, a problem of high power consumption because the sensor 24 is always in an operating state can be prevented.
Further, the controller may obtain the feature value outputted by the sensor 24 in a case that the air inlet 23 is at least partially blocked and the electronic atomization apparatus 100 is inhaled. Because the air inlet 23 is at least partially blocked, if a user inhales the electronic atomization apparatus, air pressure in the airflow channel rises quickly to reach the preset threshold, facilitating unlocking of the electronic atomization apparatus 100. A manner in which the air inlet 23 is blocked is not limited herein, and the air inlet 23 may be blocked by a finger of the user or may be blocked a mechanism or component arranged in the electronic atomization apparatus 100.
In a preferred implementation, the control method further includes:

detecting whether the electronic atomization apparatus is in a locked state; and
performing the step of obtaining the feature value outputted by the sensor if the electronic atomization apparatus is in the locked state.

In this implementation, whether the electronic atomization apparatus 100 is in the locked state is detected, so that Step S11 to Step S13 performed in the unlocked state may be prevented, thereby simplifying a control procedure of the electronic atomization apparatus 100.
In Step S12, the controller controls the electronic atomization apparatus 100 to be in the unlocked state according to the comparison result of the feature value or the parameter value derived from the feature value and the preset threshold (that is, a comparison result of the feature value and the preset threshold or a comparison result of the parameter value corresponding to the feature value and the preset threshold). The parameter value derived from the feature value is determined by the feature value.
For example, the controller may determine an air pressure value in the airflow channel R1 and another parameter value similar to the air pressure value (for example, an air pressure change amount value or an air pressure change rate value) according to the feature value outputted by the sensor 24, and determine whether to control the electronic atomization apparatus 100 to be in the unlocked state according to a comparison result of the air pressure value and a preset air pressure threshold (or the another parameter value and a preset parameter threshold). The controller may alternatively directly determine whether to control the electronic atomization apparatus 100 to be in the unlocked state according to a comparison result of the feature value outputted by the sensor 24 and a preset feature threshold.
The preset threshold may be customized by the user, and the preset threshold may be an air pressure value that can be hardly reached when a child inhales the airflow channel R1 or an air pressure value that can only be reached when the air inlet 23 is at least partially blocked.
In a preferred implementation, the control method further includes:

determining an air pressure value in the airflow channel according to the feature value outputted by the sensor;
comparing the air pressure value with a preset air pressure threshold; and
controlling the electronic atomization apparatus to be in the unlocked state if the air pressure value is greater than or equal to the preset air pressure threshold.

In this implementation, the air pressure value in the airflow channel R1 is determined according to the feature value outputted by the sensor 24. For example, a corresponding air pressure value is obtained through table lookup according to a resistance value outputted by the sensor 24, the determined air pressure value is compared with the preset air pressure threshold to determine whether the air pressure in the airflow channel R1 reaches the preset air pressure threshold, and the electronic atomization apparatus 100 is further controlled to be in the unlocked state.
In a preferred implementation, the control method further includes:

comparing the feature value outputted by the sensor with a preset feature threshold; and
controlling the electronic atomization apparatus to be in the unlocked state if the feature value outputted by the sensor is greater than or equal to the preset feature threshold.

In this implementation, the feature value outputted by the sensor 24 is directly compared with the preset feature threshold. For example, the resistance value outputted by the sensor 24 is compared with a preset resistance threshold, and the electronic atomization apparatus 100 is further controlled to be in the unlocked state.
It should be noted that, the sensor 24 may output a plurality of feature values, and the largest feature value (or another suitable feature value) in the plurality of feature values may be selected for determination; or the plurality of feature values are compared with a plurality of preset thresholds (the preset air pressure threshold, the preset feature threshold, and the like) in a one-to-one correspondence manner.
Alternatively, a plurality of sensors 24 may be arranged. For example, whether the air pressure in the airflow channel R1 reaches a first preset threshold (the preset air pressure threshold, the preset feature threshold, or the like) is determined according to a feature value outputted by a sensor 24; and whether the air pressure in the airflow channel R1 reaches a second preset threshold is then determined according to a feature value outputted by another sensor 24 (the feature value outputted by the another sensor 24 may be obtained at an interval of a period of time after the feature value outputted by the sensor 24 is obtained), where the second preset threshold (the preset air pressure threshold, the preset feature threshold, or the like) may be greater than the first preset threshold. In this way, in a case that the first preset threshold and the second preset threshold are both reached, the electronic atomization apparatus 100 is controlled to be in the unlocked state.
In a preferred implementation, the control method further includes:

determining a change rate or a change amount of air pressure in the airflow channel according to the feature value outputted by the sensor;
comparing the change rate or the change amount of the air pressure with a preset change threshold; and
controlling the electronic atomization apparatus to be in the unlocked state if the change rate or the change amount of the air pressure is greater than or equal to the preset change threshold.

In this implementation, whether the change rate or the change amount of the air pressure in the airflow channel R1 reaches the preset change threshold is determined according to the feature value outputted by the sensor 24. For example, the controller obtains feature values k1 to kn outputted by the sensor 24, obtains feature values k1 to km (m is less than n) outputted by the sensor 24 through filtering, and determines that the change amount of the air pressure in the airflow channel R1 reaches a preset change amount threshold is (km-k1) is greater than or equal to the preset change amount threshold; or the controller determines that the change rate in the airflow channel R1 reaches a preset change rate threshold if (km-k1)/t is greater than or equal to the preset change rate threshold, where t is sampling time of k1 to km. Similar to the foregoing description, corresponding air pressure values such as P1 to Pm in the airflow channel R1 may be first determined according to the feature values k1 to km outputted by the sensor 24, and a relationship between a change amount (Pm-P1) or a change rate (Pm-P1)/t and the preset change threshold is then determined. In an alternative implementation, whether the change rate or the change amount of the air pressure in the airflow channel R1 reaches the preset change threshold may be determined according to a currently obtained feature value (for example, kt) outputted by the sensor 24 and a preset feature value (for example, k0) of the sensor 24, that is, a relationship between (kt+k0) or (kt-k0)/t and the preset change threshold. Alternatively, k0 may be a feature value outputted by the sensor 24 in previous sampling (for example, a feature value obtained through sampling when the electronic atomization apparatus is locked). Once it is determined that the change rate or the change amount in the airflow channel R1 reaches the preset change threshold, the electronic atomization apparatus 100 is controlled to be in the unlocked state. In this case, if it is detected that the electronic atomization apparatus 100 is inhaled, the atomization assembly 11 may be normally started up for atomization.
It should be noted that, in the foregoing comparison situations, the electronic atomization apparatus may be alternatively controlled to be in the unlocked state when the value is less than or equal to the preset threshold (the preset air pressure threshold, the preset feature threshold, the preset change threshold, or the like).
It should be further noted that, comparison of the air pressure value and the preset air pressure threshold, comparison of the feature value and the preset feature threshold, comparison of the change rate and the preset change rate threshold, and comparison of the change amount and the preset change amount threshold may be implemented through a comparator inside the MCU; or may be implemented through a comparison circuit independent of the MCU.
In another preferred implementation, the control method further includes:

detecting whether the electronic atomization apparatus is inhaled within preset time; and
controlling the electronic atomization apparatus to be in a locked state if the electronic atomization apparatus is not inhaled within the preset time.

Generally, the preset time may be 5 minutes, 10 minutes, or the like, and the preset time specifically may be set by the user.
In this way, when the electronic atomization apparatus 100 is not inhaled, the electronic atomization apparatus 100 is controlled to be in the locked state in time. Therefore, children can be further protected.
FIG. 3 is a schematic diagram of an operating method for an electronic atomization apparatus according to an example of this application.
As shown in FIG. 3, the operating method includes:

Step S21. Blocking at least a part of the air inlet.
Step S23. Inhaling the electronic atomization apparatus, to cause the sensor to sense the air pressure in the airflow channel and output the feature value; obtain the feature value outputted by the sensor through a controller; and controlling the electronic atomization apparatus to be in an unlocked state according to a comparison result of the feature value outputted by the sensor or a parameter value derived from the feature value and a preset threshold.

In a preferred implementation, the part of the air inlet is blocked by a part of a body of a user or adjusting a mechanism of the electronic atomization apparatus. For example, the part of the air inlet 23 is blocked by a finger or a palm. This operating manner is easy and convenient.
Due to children's thinking and the simplicity of the operations, it is generally difficult for children to consciously block the air inlet 23 to unlock and inhale the electronic atomization apparatus 100. Therefore, this operating manner can protect children.
The following describes an unlocking and unlocking process of the electronic atomization apparatus 100 with reference to FIG. 1 and FIG. 4:
Whether the electronic atomization apparatus 100 is in a locked state is first determined (Step S31).
If the electronic atomization apparatus 100 is in the locked state, a user blocks at least a part of the air inlet 23 through a finger of the user, and then inhales the electronic atomization apparatus 100, which may be one or more puffs (Step S32). The controller then obtains the feature value outputted by the sensor 24; and determines whether the air pressure in the airflow channel R1 reaches the preset threshold according to the feature value outputted by the sensor 24 (Step S33 and Step S34).
If the air pressure in the airflow channel R1 reaches the preset threshold, the controller controls the electronic atomization apparatus 100 to be in an unlocked state (Step S35). Otherwise, the controller obtains the feature value outputted by the sensor 24; and determines whether the air pressure in the airflow channel R1 reaches the preset threshold according to the feature value outputted by the sensor 24.
If the electronic atomization apparatus 100 is in an unlocked state, the controller determines whether the electronic atomization apparatus 100 is inhaled within preset time (Step 36).
If the electronic atomization apparatus 100 is not inhaled within the preset time, the controller controls the electronic atomization apparatus 100 to be in a locked state (Step S37); otherwise, the controller continues to perform Step S36.
In another example, the controller may be further configured to read program code for controlling an electronic atomization apparatus stored in a storage medium and execute the program code, to implement the steps of the control method for an electronic atomization apparatus.
The storage medium may be a part of the controller or may be independent of the controller.
