The child lock related technologies currently used in electronic atomization devices generally use sensors to detect the user's operation, and use the detection data to identify whether the user is an adult or a child. If the user is identified as a child, the child lock is turned on to prevent children from using the electronic atomization device. However, the sensitivity of the sensor used in the related technology is difficult to calibrate. When the sensor sensitivity is too low, it is easy to mistakenly identify children as adults, thereby making the child lock function ineffective; when the sensor sensitivity is too high, it is easy to mistakenly identify adults as children, thereby easily triggering the child lock function by mistake, thereby affecting the normal use of the user and causing inconvenience to the user.

[0046] In this embodiment, refer to Figure 1 The electronic atomization device is provided with an air pressure sensor 100, a one-way airflow attenuation component 200, a control unit and a nozzle 300, and an atomization assembly 400, wherein the nozzle 300 connects the inside of the electronic atomization device with the external space. When using the electronic atomization device, the user can place the mouth at the nozzle 300 and suck the nozzle 300 to generate a suction airflow in the electronic atomization device, or blow the nozzle 300 to generate a blowing airflow in the electronic atomization device.

[0047] In this embodiment, the control unit can be arranged in the power supply device, and the control unit is connected to the air pressure sensor 100 and other components through a data bus. Figure 2 , a microprocessor unit MCU can be used as a control unit; the control unit is connected to the air pressure sensor 100 and the atomizer assembly 400 respectively through a data bus, triggers the air pressure sensor 100 to detect the air pressure, obtains the air pressure information detected by the air pressure sensor 100, performs atomization control according to the air pressure information, generates a control signal for triggering atomization, or a control signal for triggering stopping atomization, and when these control signals are sent to the atomizer assembly 400, the atomizer assembly 400 can be controlled to atomize or stop atomizing the atomization medium such as smoke oil.

[0048] Reference Figure 2The control unit is also connected to the LED display, the charging chip and the lithium battery. The control unit integrates the display control function, which can control the LED display to display working parameters and other contents; the control unit integrates power management functions such as temperature monitoring, power monitoring, low voltage protection, overcurrent protection and charging management; the lithium battery supplies power to the control unit, the air pressure sensor 100 and the atomization assembly 400 and other components, and is protected by the lithium battery protection function. When the charging chip is connected to an external power source, the lithium battery can be charged.

[0049] In this embodiment, refer to Figure 1 The one-way airflow attenuation component 200 is provided with two ends, namely a first end 201 and a second end 202, wherein the first end 201 is connected to the position on the side of the air pressure sensor 100, and the second end 202 is connected to the position on the side of the suction nozzle 300, so that the gas on the side of the air pressure sensor 100 can enter from the first end 201 of the one-way airflow attenuation component 200, flow out from the second end 202 through the one-way airflow attenuation component 200, and thus flow to the side of the suction nozzle 300. Similarly, the gas on the side of the suction nozzle 300 can also enter from the second end 202 of the one-way airflow attenuation component 200, flow out from the first end 201 through the one-way airflow attenuation component 200, and thus flow to the side of the air pressure sensor 100.

[0050] In this embodiment, the characteristic of the one-way airflow attenuation component 200 is that the resistance encountered by the airflow in the one-way airflow attenuation component 200 is related to the direction of the airflow. When other parameters are the same, the resistance encountered by the airflow flowing in one direction is much greater than the resistance encountered by the airflow flowing in the opposite direction. The direction in which the airflow encounters less resistance can be called the downstream direction, and correspondingly, the direction in which the airflow encounters greater resistance can be called the upstream direction. When the airflow flows in the downstream direction, the airflow and the air pressure generated by it will not be "attenuated", and when the airflow flows in the upstream direction, the airflow and the air pressure generated by it will be "attenuated". Devices that meet such characteristics include Tesla one-way valves and valve nozzles, etc., so Tesla one-way valves can be used as the one-way airflow attenuation component 200, for example Figure 1 The airflow one-way attenuation component 200 shown in FIG. 1 includes a Tesla one-way valve.

[0051] In this embodiment, the air pressure sensor 100 can convert the air pressure physical quantity into the capacitance physical quantity based on the thin film structure, and then convert the capacitance physical quantity into data in a corresponding format, thereby obtaining air pressure information indicating the air pressure direction and air pressure magnitude measured by the air pressure sensor 100. In this embodiment, the air pressure direction can indicate the high and low direction of the air pressure detected by the air pressure sensor 100 relative to the atmospheric pressure. For example, when the user Figure 1When the suction nozzle 300 is used to draw air, a suction airflow will be generated inside the electronic atomization device. The air pressure at the position of the air pressure sensor 100 is less than the atmospheric pressure, and the air pressure direction detected by the air pressure sensor 100 is negative pressure. Figure 1 When the nozzle 300 in the electronic atomization device is blown, a blowing airflow will be generated inside the electronic atomization device, and the air pressure at the position of the air pressure sensor 100 is greater than the atmospheric pressure, then the air pressure direction detected at the position of the air pressure sensor 100 is positive pressure; when Figure 1 When the suction nozzle 300 is not being sucked or blown, the air pressure at the position of the air pressure sensor 100 is equal to the atmospheric pressure, and the air pressure direction detected at the position of the air pressure sensor 100 is zero pressure; the air pressure magnitude can indicate the height of the air pressure detected by the air pressure sensor 100 relative to the atmospheric pressure. For example, the absolute magnitude of the air pressure detected by the air pressure sensor 100 can be subtracted from the absolute magnitude of the atmospheric pressure, and the positive and negative signs of the obtained data are indicated as the air pressure direction, wherein the positive sign indicates positive pressure and the negative sign indicates negative pressure, and the absolute numbers after the positive and negative signs indicate the air pressure magnitude.

[0052] In this embodiment, the circuit structure of the air pressure sensor 100 is as follows: Figure 3 As shown, U2 represents the air pressure sensor 100. Figure 3 The air pressure sensor 100 is provided with two output ports, INT and FREQ, which are both connected to the data interface of the control unit. Among them, INT is an interrupt output port, which can output an interrupt signal to the control unit to wake up the control unit in a dormant state; FREQ is an air pressure information output port, which can indicate a specific air pressure direction and air pressure magnitude by outputting a square wave of a specific frequency.

[0053] In this embodiment, the air pressure sensor 100 sends the detected air pressure information to the control unit through the FREQ output port, and the control unit processes the air pressure direction and air pressure magnitude contained in the air pressure information to set the child lock working state. Specifically, at any time, the child lock working state is specifically one of the "locked state" and the "unlocked state".

[0054] In this embodiment, the working principle of the electronic atomization device is that: by setting an air pressure sensor 100, the air pressure information generated by the user through inhalation or blowing can be detected for processing by the control unit, and the control unit can judge whether the user is an adult or a child based on the air pressure information, thereby further setting the child lock working state; wherein, by setting an airflow unidirectional attenuation component 200 between the air pressure sensor 100 and the air pressure change source, i.e., the nozzle 300, and making the downstream direction of the airflow unidirectional attenuation component 200 from its first end (the end connected to the air pressure sensor 100) to the second end (the end connected to the nozzle 300), and the reverse direction from its second end (the end connected to the nozzle 300) to the first end (the end connected to the air pressure sensor When the user inhales, the direction of the inhaled airflow is the same as the downstream direction of the one-way airflow attenuation component 200, and the resistance of the inhaled airflow to the one-way airflow attenuation component 200 is small. Therefore, the air pressure change at the position of the air pressure sensor 100 is not attenuated relative to the air pressure change caused by the user's inhalation. Therefore, the air pressure sensor 100 can maintain the original trigger sensitivity to the user's inhalation. When the user blows, the direction of the blowing airflow is the same as the upstream direction of the one-way airflow attenuation component 200, and the resistance of the blowing airflow to the one-way airflow attenuation component 200 is large. Therefore, the air pressure change at the position of the air pressure sensor 100 is attenuated to a large extent relative to the air pressure change caused by the user's blowing, etc. The effect is that when the trigger sensitivity of the air pressure sensor 100 remains unchanged, the air pressure direction caused by the user's blowing can be detected in a larger range. Since adults are more likely to generate large-value positive pressure air pressure information by blowing than children, the air flow unidirectional attenuation component 200 is provided, which is equivalent to expanding the air pressure information detection range of the air pressure sensor 100, so that the detection range of the air pressure direction and the air pressure magnitude is large enough to match the difference between adults and children (for example, the air pressure sensor 100 can measure the air pressure magnitude of 0-5kPa, while adults can generally generate the air pressure magnitude of 10kPa by blowing, and children can generally generate the air pressure magnitude of 6kPa by blowing, both of which are beyond the air pressure sensor). 100, so that it is impossible to distinguish between adults and children; after the air pressure is attenuated by the one-way airflow attenuation component 200, the maximum degree of the air pressure generated by adults that can be detected by the air pressure sensor 100 is 5kPa, and the maximum degree of the air pressure generated by children that can be detected by the air pressure sensor 100 is 3kPa, then the same air pressure sensor 100 can detect the difference between the two), which is conducive to the control unit judging whether the user is an adult or a child according to the air pressure information detected by the air pressure sensor 100, which is conducive to correctly setting the working state of the child lock, reducing the possibility of failure or false triggering of the child lock function, and can prevent children from using the electronic atomization device, and can ensure that adults use the electronic atomization device normally;Moreover, the air pressure attenuation generated by the one-way airflow attenuation component 200 has a filtering effect, which can reduce the fluctuation of the air pressure information and improve the stability of the air pressure information, which is conducive to the air pressure sensor 100 to perform high-precision air pressure detection.

[0055] In this embodiment, the control program can be run by the control unit to execute the child lock control method of the electronic atomization device. Figure 4 , the child lock control method of the electronic atomization device comprises the following steps:

[0056] When setting the working state of the child lock according to the air pressure information, the following steps can be performed:

[0057] S1. Control the air pressure sensor to detect the air pressure at the first end of the one-way airflow attenuation component to obtain the air pressure direction and pressure size;

[0058] S2. When the air pressure direction indicates positive pressure, determine the air pressure;

[0059] S3. When the air pressure meets the threshold condition, the child lock working state of the electronic atomization device is set to the unlocked state.

[0060] In this embodiment, the flow of the control program executed by the control unit is as follows: Figure 5 shown.

[0061] In step S1 , the control unit parses the air pressure direction and the air pressure magnitude from the air pressure information detected by the air pressure sensor 100 .

[0062] In step S2, the control unit further determines the magnitude of the air pressure when determining that the air pressure direction indicates positive pressure.

[0063] In step S3, when the control unit determines that the air pressure meets the threshold condition, the control unit sets the child lock working state to the unlocked state; otherwise, the control unit sets the child lock working state to the locked state.

[0064] Specifically, when the air pressure meets the threshold condition, if the child lock working state was originally in a locked state, the control unit changes the child lock working state to an unlocked state; if the child lock working state was originally in an unlocked state, the control unit continues to maintain the child lock working state as an unlocked state; when the air pressure does not meet the threshold condition, if the child lock working state was originally in a locked state, the control unit continues to maintain the child lock working state as a locked state; if the child lock working state was originally in an unlocked state, the control unit changes the child lock working state to a locked state.

[0065] By executing steps S1-S3, the user can blow air into the nozzle 300 so that the air pressure detected by the air pressure sensor 100 meets the threshold condition, thereby setting the child lock working state to the unlocked state, and the user can use the electronic atomization device normally to inhale the e-liquid.

[0066] In this embodiment, the principle of executing steps S1-S3 is that: by setting the one-way airflow attenuation component 200 between the air pressure sensor 100 and the air pressure change source, that is, the suction nozzle 300, and making the downstream direction of the one-way airflow attenuation component 200 from its first end (the end connected to the air pressure sensor 100) to the second end (the end connected to the suction nozzle 300), and the reverse direction from its second end (the end connected to the suction nozzle 300) to the first end (the end connected to the air pressure sensor 100), when the user inhales, the direction of the suction airflow is the same as the downstream direction of the one-way airflow attenuation component 200, and the suction airflow is subject to less resistance from the one-way airflow attenuation component 200, so the air pressure sensor 100 The air pressure change at the position of the air pressure sensor 100 is not attenuated relative to the air pressure change caused by the user's inhalation, so the original trigger sensitivity to the user's inhalation can be maintained when executing step S1; and when the user blows, the direction of the blowing airflow is the same as the counterflow direction of the airflow unidirectional attenuation component 200, and the blowing airflow is subject to a greater resistance from the airflow unidirectional attenuation component 200. Therefore, the air pressure change at the position of the air pressure sensor 100 is attenuated to a greater extent relative to the air pressure change caused by the user's blowing, which is equivalent to the air pressure direction of the positive pressure caused by the user's blowing being detected in a larger range when executing step S2 when the trigger sensitivity of the air pressure sensor 100 remains unchanged. Since adults are more likely to produce large values ​​by blowing than children, Therefore, by using the one-way airflow attenuation component 200 for detection, it is equivalent to expanding the detection range of the air pressure information, so that the detection range of the air pressure direction and the air pressure magnitude is large enough to match the difference between adults and children (for example, the air pressure sensor 100 can measure the air pressure magnitude of 0-5kPa, while adults can generally generate an air pressure magnitude of 10kPa by blowing, and children can generally generate an air pressure magnitude of 6kPa by blowing, both of which exceed the range of the air pressure sensor 100, making it impossible to distinguish between adults and children; and after the air pressure of the blowing is attenuated by the one-way airflow attenuation component 200, the air pressure of the blowing generated by the adult can be detected by the air pressure sensor 100 The maximum level is 5kPa, and the maximum level of the blowing air pressure generated by children that can be detected by the air pressure sensor 100 is 3kPa, then the same air pressure sensor 100 can detect the difference between the two), which is beneficial for the control unit to judge whether the user is an adult or a child based on the air pressure information detected by the air pressure sensor 100, which is beneficial for correctly setting the working state of the child lock, reducing the possibility of failure or false triggering of the child lock function, which can not only prevent children from using electronic atomization devices, but also ensure that adults use electronic atomization devices normally; moreover, the air pressure attenuation generated by the one-way airflow attenuation component 200 has a filtering effect, which can reduce the fluctuation of air pressure information, improve the stability of air pressure information, and is beneficial for high-precision air pressure detection.

[0067] In this embodiment, when the control unit executes step S3, that is, when the air pressure meets the threshold condition, the child lock working state of the electronic atomization device is set to the unlocked state, the following steps can be specifically performed:

[0068] S301A. Set a first threshold;

[0069] S302A. Determine the corresponding vital capacity data according to the air pressure;

[0070] S303A. When the vital capacity data is greater than or equal to the first threshold, the child lock working state is set to the unlocked state.

[0071] Steps S301A-S303A are the first execution mode of step S3. The process of steps S301A-S303A is as follows: Figure 6 As shown, Figure 6 Yes Figure 5 Part of the control flow in is marked with a dotted box.

[0072] Reference Figure 6 , the first threshold value can be set according to the physical differences between adults and children. For example, the electronic atomization device is used by people in region A, and adults in region A can generally use 2000mL of lung capacity in a regular blowing operation, while children in region A generally cannot use 2000mL of lung capacity, so the first threshold value can be set to 2000mL.

[0073] In step S302A, refer to Figure 6 , a set of vital capacity-inflation pressure relationship data can be obtained by performing an inflating test on people with known vital capacity in advance, recording the inflating pressure generated by people with different vital capacities in a routine inflating operation, and performing data fitting to make discrete data tend to be continuous, thereby obtaining an air pressure-vital capacity relationship table. The air pressure-vital capacity relationship table can be stored in the control unit in advance. When detecting the air pressure, the air pressure can be collected 100 times within 1 second, and the air pressure can be accumulated and averaged to reduce the error. According to the average air pressure obtained, the air pressure-vital capacity relationship table can be queried to determine the vital capacity data.

[0074] By executing step S302A, the blowing operation of the user can be detected, and the obtained vital capacity data can represent the size of the vital capacity used by the user in this blowing operation.

[0075] In step S303A, the vital capacity data is compared with a first threshold value (2000mL) having a vital capacity dimension. If the vital capacity data is greater than or equal to the first threshold value (2000mL), the control unit sets the child lock working state to an unlocked state; if the vital capacity data is less than the first threshold value (2000mL), the control unit sets the child lock working state to a locked state.

[0076] In this embodiment, the principle of executing steps S301A-S303A is that by comparing the measured vital capacity data with the first threshold, the user's vital capacity can be determined, and thus based on the characteristic difference that the vital capacity of adults is generally larger than that of children, it is determined whether the user is an adult or a child, thereby accurately setting the child lock working state to a locked state or an unlocked state; moreover, combined with the airflow unidirectional attenuation component 200 in this embodiment, it has the advantage of expanding the air pressure information detection range of the air pressure sensor 100, so that the detection range of the air pressure direction and the air pressure size is large enough to match the difference between adults and children, and has a good judgment accuracy rate for whether the user is an adult or a child.

[0077] In this embodiment, when the control unit executes step S3, that is, when the air pressure meets the threshold condition, the child lock working state of the electronic atomization device is set to the unlocked state, the following steps can be specifically performed:

[0078] S301B tracks and detects the air pressure to obtain a time curve of the air pressure change;

[0079] S302B extracts features from the pressure change curve over time to obtain curve feature information;

[0080] S303B compares the curve feature information with the reserved feature information;

[0081] S304B. When the curve characteristic information matches the reserved characteristic information, the child lock working state is set to the unlocked state.

[0082] Steps S301B-S304B are a second execution method of step S3.

[0083] In step S301B, the control unit controls the air pressure sensor 100 to sample the air pressure information within a period of time, at t1, t2, ..., t n At the same time, p1, p2, ... p are measured n The same air pressure. For p1, p2, ... p n Fitting is performed to obtain the air pressure time variation curve p(t).

[0084] In step S302B, features such as mean, variance, extreme point position, inflection point position, etc. can be extracted from the air pressure time variation curve p(t) as curve feature information, and pre-stored reserved feature information can be read from the control unit. Among them, the reserved feature information also includes feature information of types such as mean, variance, extreme point position, inflection point position, etc. The reserved feature information can be obtained by collecting information and extracting features from all owners of the electronic atomization device during the purchase and registration of the electronic atomization device.

[0085] In step S303B, the curve feature information obtained in step S302B is compared with the reserved feature information. Specifically, the mean values, variances, extreme point positions, inflection point positions, etc. of the two can be compared. If all features are consistent, or more than a certain number of features are consistent, it can be determined that the curve feature information is consistent with the reserved feature information. Otherwise, it is determined that the curve feature information is inconsistent with the reserved feature information.

[0086] In step S303B, when the curve characteristic information is judged to be consistent with the reserved characteristic information, the control unit sets the child lock working state to the unlocked state; when the curve characteristic information is judged to be inconsistent with the reserved characteristic information, the control unit sets the child lock working state to the locked state.

[0087] In this embodiment, the principle of executing steps S301B-S304B is that due to the influence of physiological characteristics and personal habits, different people have different blowing actions, so the characteristic information formed by the size of the blowing air pressure is also different. Therefore, the user can be identified by the characteristic information formed by the size of the blowing air pressure; the reserved characteristic information can represent the characteristic information of a specific person such as the owner of the electronic atomization device, and through purchase or registration and other links, it can be ensured that the person corresponding to the reserved characteristic information is an adult; by comparing the curve characteristic information with the reserved characteristic information, it can be determined whether the current user of the electronic atomization device is a specific person. When the curve characteristic information is consistent with the reserved characteristic information, it can be determined that the current user is an adult, so that the child lock working state can be set to the unlocked state, so that the user can use the electronic atomization device normally. The function of the electronic atomization device; by executing steps S301B-S304B, in addition to determining whether the current user is an adult, it can also be determined whether the current user is a specific person such as the owner of the electronic atomization device, so that the child lock working state can be set to a locked state to prohibit use by people other than specific people, so that the electronic atomization device can be exclusively used by specific people, which is beneficial to ensuring the safe use of the electronic atomization device; and, because the one-way airflow attenuation component 200 expands the air pressure information detection range, it is possible to detect air pressure information in a larger range, so that characteristic information can be obtained in a larger range (for example, a larger maximum air pressure value, etc.), which is beneficial to enhancing the recognizability of the characteristic information formed by the air pressure of the blowing, and enhancing the reliability of identifying whether the current user is a specific person based on the characteristic information.

[0088] In this embodiment, the control unit may further perform the following steps based on performing steps S1-S3:

[0089] S4. When the air pressure direction indicates non-negative pressure, the timing is continued. When the air pressure direction indicates negative pressure, the timing is reset to zero, thereby obtaining the timing duration;

[0090] S5. When the timing duration is greater than the second threshold, the child lock working state is set to the locked state.

[0091] The process of steps S4-S5 is as follows: Figure 7 As shown, Figure 7 Yes Figure 5 Part of the control flow in is marked with a dotted box.

[0092] Reference Figure 7In step S4, the control unit can run the timer to trigger the air pressure sensor 100 to continuously sample the air pressure direction. When the air pressure direction is detected to be non-negative pressure (specifically, it can be positive pressure or zero pressure) for the first time, the timer starts timing from zero, and the timing result of the timer is the timing duration. The control unit determines in real time whether the timing duration of the timer is greater than the second threshold (3s). If the timing duration is greater than the second threshold, the control unit sets the child lock working state to the locked state. Otherwise, the timer is kept continuously timing and the child lock working state is set to the unlocked state.

[0093] In step S4, when the timer is timing, as long as the air pressure direction is non-negative pressure, the timer will continue to timing. Once the control unit detects that the air pressure direction is negative pressure, the timer will be cleared. When the air pressure direction is detected to be non-negative pressure next time, the timer will start timing from zero again.

[0094] In this embodiment, the principle of executing steps S4-S5 is that when the air pressure direction indicates non-negative pressure, it indicates that the user does not inhale the nozzle 300 (specifically, the user may blow air into the nozzle 300, or does not perform any operation on the nozzle 300), that is, the electronic atomization device is in an idle state at this time; when the air pressure direction indicates negative pressure, it indicates that the user inhales the nozzle 300, that is, the electronic atomization device is in use at this time; therefore, the timing duration obtained by step S4 actually indicates the duration of the electronic atomization device being continuously in an idle state. When the timing duration exceeds the second threshold, it can be determined that the electronic atomization device has been idle for a long enough time, and the child lock working state is set to a locked state to avoid misuse by children, while adults can set the child lock working state to an unlocked state by triggering the air pressure sensor 100, thereby using the electronic atomization device normally; by executing steps S4-S5, long-term automatic protection of the electronic atomization device can be achieved, and automatic movement of the child lock function can be achieved.

[0095] In this embodiment, when the control unit executes step S5, that is, when the timing duration is greater than the second threshold, the child lock working state is set to the locked state, the following steps can be specifically performed:

[0096] S501. When the timing duration is greater than the second threshold, enter the sleep state;

[0097] S502. Detect the sleep duration;

[0098] S503. When the sleep duration is greater than the third threshold, the child lock working state is set to the locked state;

[0099] S504: When the air pressure is greater than a fourth threshold, wake up from the sleep state.

[0100] The process of steps S501-S504 is as follows: Figure 8 As shown, Figure 8 Yes Figure 5 Part of the control flow in is marked with a dotted box.

[0101] Reference Figure 8 In step S501, when the timer duration exceeds the second threshold value (3s), the control unit enters a dormant state. In the dormant state, the control unit can only keep the components related to the detection of the interrupt signal working, and shut down other components of itself, as well as the external atomization component 400, LED display, etc., so as to reduce power consumption.

[0102] In step S502, the timer starts counting from zero when the control unit enters the sleep state, thereby obtaining the sleep duration, which indicates the duration of the current sleep state.

[0103] In step S503, when the sleep time obtained by the timer is greater than the third threshold value (30s), the control unit sets the child lock working state to the locked state.

[0104] In step S504, in the dormant state, the air pressure sensor 100 also keeps monitoring the air pressure, but does not send the air pressure information to the control unit through the FREQ output port, but judges the air pressure information by the air pressure sensor 100 itself. Figure 8 The air pressure sensor 100 can set the fourth threshold value to 150Pa. When the air pressure sensor 100 judges that the latest detected air pressure is greater than the fourth threshold value (specifically, the air pressure can be negative pressure or positive pressure), the air pressure sensor 100 sends an interrupt signal to the control unit through the interrupt output port INT, thereby waking up the control unit from the sleep state.

[0105] By executing steps S501-S504, the control unit can first enter a sleep state when the timing duration exceeds the second threshold, and after the sleep state reaches a certain duration, the child lock working state is set to a locked state, thereby reducing power consumption and maintaining the battery life of the electronic atomization device; moreover, the user only needs to suck or blow on the nozzle 300 of the electronic atomization device with a certain force to wake up the electronic atomization device, providing convenience for the user.

[0106] In this embodiment, the control unit may further perform the following steps based on performing steps S1-S3 or S1-S5:

[0107] When the child lock is in the locked state, a control signal to stop atomization is output;

[0108] S6. When the child lock is in unlocked state and the air pressure direction indicates negative pressure, a control signal for atomization is output;

[0109] S7. When the child lock is in the locked state, a control signal to stop atomization is output.

[0110] The process of steps S6-S7 is as follows: Fig. 9 As shown, Fig. 9 Yes Figure 5 Part of the control flow in is marked with a dotted box.

[0111] When executing step S6, refer to Fig. 9 When the child lock is in the unlocked state, the control unit determines whether the air pressure direction is positive pressure, zero pressure or negative pressure based on the air pressure information sent by the air pressure sensor 100; when the air pressure direction indicates negative pressure and the child lock is in the unlocked state, the control unit outputs a control signal for atomization.

[0112] When the air pressure direction in the air pressure information indicates negative pressure, it indicates that the user is sucking on the nozzle 300. When the child lock is in the unlocked state, the control unit sends a control signal for atomization to the atomization component 400. The atomization component 400 receives the control signal and atomizes the atomization medium in the electronic atomization device according to the control signal. Specifically, if the atomization component 400 is atomizing the atomization medium before receiving the control signal, the atomization component 400 keeps atomizing the atomization medium; if the atomization component 400 stops atomizing the atomization medium before receiving the control signal, the atomization component 400 starts atomizing the atomization medium.

[0113] When executing step S7, refer to Fig. 9 When the child lock is in the locked state, the control unit outputs a control signal to stop atomization regardless of the air pressure information received by the control unit. Specifically, if the control unit originally outputs a control signal to atomize, the control unit can switch to output a control signal to stop atomization; if the control unit originally outputs a control signal to stop atomization, the control unit continues to output a control signal to stop atomization.

[0114] When the child lock is in the locked state, the control unit sends a control signal to stop atomization to the atomizer assembly 400. The atomizer assembly 400 receives the control signal and stops atomizing the atomizing medium in the electronic atomizer device according to the control signal. Specifically, if the atomizer assembly 400 is atomizing the atomizing medium before receiving the control signal, the atomizer assembly 400 stops atomizing the atomizing medium; if the atomizer assembly 400 has stopped atomizing the atomizing medium before receiving the control signal, the atomizer assembly 400 continues to stop atomizing the atomizing medium.

[0115] Specifically, the content or form of the control signal for stopping atomization is different from the control signal for performing atomization. Alternatively, the atomization assembly 400 may be configured to stop atomization by default when the control signal for performing atomization is not received. In this way, the control unit may not send a control signal for performing atomization to the atomization assembly 400 when the child lock working state is the locked state, thereby achieving the effect of sending a control signal for stopping atomization to the atomization assembly 400.

[0116] pass Fig. 9 In the control flow indicated in, i.e., steps S6-S7, when in the locked state, the atomizer assembly 400 stops atomizing the atomizing medium, and the user cannot inhale the e-liquid from the suction nozzle 300. By stopping the supply of e-liquid to the user, the user is prevented from using the electronic atomizer device, thereby realizing the child lock function; when in the unlocked state, the control unit determines that the user inhales the suction nozzle 300 according to the negative pressure detected by the air pressure sensor 100, thereby triggering the atomizer assembly 400 to atomize the atomizing medium, and the user can inhale the e-liquid from the suction nozzle 300, so that the user can use the function of the electronic atomizer device normally.
