[0048] Please refer to FIG. 1, which is a circuit block diagram of an atomization device 1000 provided by an embodiment of the present application. The atomization device 1000 at least includes an acoustic control system 100. The acoustic control system 100 includes a sound signal acquisition circuit 10 and an acoustic control instruction processing circuit 20.

[0049] Among them, the sound signal acquisition circuit 10 can be arranged on a PCB board, or can be packaged in a chip. The acoustic control instruction processing circuit 20 can be arranged on a PCB board, or can be packaged in a chip. In the present embodiment, the acoustic control instruction processing circuit 20 is packaged in a chip, and further optionally, the acoustic control instruction processing circuit 20 is a part of the functional module with a microcontroller unit (Microcontroller Unit, MCU) as the main control chip. The microcontroller unit is also called single chip microcomputer (Single Chip Microcomputer) or single chip microcomputer.

[0050] The sound signal acquisition circuit 10 is arranged outside the single-chip microcomputer, and a signal output end of the sound signal acquisition circuit 10 is electrically connected to a pin terminal of the single-chip microcomputer.

[0051] Referring to FIG. 2, the sound signal acquisition circuit 10 includes a sound acquisition element 11, a signal amplification circuit 12, and a signal conversion circuit 13 which are electrically connected.

[0052] The sound acquisition element 11 is configured to acquire a sound signal. The sound acquisition element 11 can be an element configured to convert a sound signal (vibration signal) into an analog electric signal or a digital electric signal. In an optional embodiment, the sound acquisition element 11 includes, but is not limited to, a MEMS acoustic microphone or an ECM electret acoustic microphone. The sound acquisition element 11 is equivalent to a variable capacitor, and an equivalent capacitance value of the sound acquisition element 11 changes with the amplitude of the sound signal, thereby acquiring the sound signal, for example, an electret condenser microphone (ECM).

[0053] The signal amplification circuit 12 is configured to amplify the sound signal. The signal amplification circuit 12 includes, but is not limited to, an amplification circuit formed by a transistor having an amplification function, and can also be an operational amplifier.

[0054] The signal conversion circuit 13 is configured to convert the sound signal into a sound control instruction. The sound signal is an analog signal. The sound control instruction is a digital pulse signal, which can also be referred to as a sound control switch signal. The signal conversion circuit 13 is a circuit configured to convert an analog signal into a digital signal. When the sound control instruction is a positive pulse, one high-level pulse (or pulse group) represents that one sound signal is received, and one low-level pulse (or pulse group) represents that there is no sound signal.

[0055] When the sound control instruction is a negative pulse, one low-level pulse (or pulse group) represents that one sound signal is received, and one high-level pulse (or pulse group) represents that there is no sound signal.

[0056] The sound signal acquisition circuit 10 is electrically connected to the sound control instruction processing circuit 20. For example, the sound signal acquisition circuit 10 is a part of a circuit module or a functional module in the single-chip microcomputer. An output end of the sound signal acquisition circuit 10 is electrically connected to a pin terminal of the single-chip microcomputer which is electrically connected to the sound control instruction processing circuit 20 through a wire.

[0057] The sound control instruction processing circuit 20 is configured to determine whether the sound control instruction meets a condition for triggering the atomization device 1000 to switch a working state when the atomization device 1000 is in a target state, and trigger the atomization device 1000 to switch the working state when the sound control instruction meets the condition for triggering the atomization device 1000 to switch the working state.

[0058] The target state is different according to different switching working states, and specific descriptions will be given later. In this embodiment, the sound control instruction processing circuit 20 determines whether the sound control instruction satisfies the condition of triggering the atomization device 1000 to switch the working state according to the current target state of the atomization device 1000 and whether the received sound control instruction is the target sound control instruction corresponding to the target working state, and switches to the target working state according to the determination.

[0059] The switching working state includes but is not limited to the switching of unlocking and locking, or the switching of starting and stopping, or the switching of increasing or decreasing power, etc. Therefore, the target working state includes but is not limited to the unlocking state, the locking state, the starting state, the stopping state, the power increasing, the power decreasing, etc.

[0060] The atomization device 1000 provided by the application comprises a sound signal acquisition circuit 10, a sound control instruction processing circuit 20, and a sound control instruction execution circuit 30. The sound signal acquisition circuit 10 comprises a sound acquisition element 11, a signal amplification circuit 12, and a signal conversion circuit 13 which are electrically connected. The sound acquisition element 11 is used to acquire a sound signal. The signal amplification circuit 12 is used to amplify the sound signal. The signal conversion circuit 13 is used to convert the sound signal into a sound control instruction which is a digital pulse signal. The sound control instruction processing circuit 20 is electrically connected to the sound signal acquisition circuit 10. The sound control instruction processing circuit 20 is used to determine whether the sound control instruction satisfies the condition of triggering the atomization device 1000 to switch the working state when the atomization device 1000 is in a target state. The sound control instruction processing circuit 20 is used to trigger the atomization device 1000 to switch the working state when the sound control instruction satisfies the condition of triggering the atomization device 1000 to switch the working state. On the one hand, the sound control instruction triggering the atomization device 1000 to switch the working state does not need to set a switching switch button on the atomization device 1000, which is compatible with the appearance consistency of the atomization device 1000. On the other hand, the way of the sound control instruction triggering the atomization device 1000 to switch the working state is relatively novel and simple, which improves the simplicity of user operation.

[0061] The specific structure of the sound signal acquisition circuit 10 will be illustrated below in combination with the drawings.

[0062] Please refer to FIG. 3, which is a circuit topology diagram of a sound signal acquisition circuit 10 provided by an embodiment of the application. The sound signal acquisition circuit 10 acquires a sound signal through an ECM electret acoustic microphone C1 or a MEMS acoustic microphone, amplifies the weak sound signal, converts the amplified sound signal into a corresponding pulse switch output, and finally shapes the pulse switch output into a standard switch pulse signal (sound control instruction).

[0063] Specifically, please refer to Figure 3, the sound collecting element 11 includes an ECM electret acoustic microphone C1, a first transistor Q1 (N-JFET transistor), and a first resistor R1. The ECM electret acoustic microphone C1 collects sound and performs preliminary amplification.

[0064] One end of the ECM electret acoustic microphone C1 is grounded, and the other end is electrically connected to the base of the first transistor Q1. The emitter of the first transistor Q1 is grounded, and the collector of the first transistor Q1 is electrically connected to one end of the first resistor R1. The other end of the first resistor R1 is loaded with a VCC voltage. The first resistor R1 is a bias resistor for the first transistor Q1.

[0065] The ECM electret acoustic microphone C1, the first transistor Q1, and the first resistor R1 collect sound signals. The ECM electret acoustic microphone C1 and the first transistor Q1 can be integrated and packaged together.

[0066] Please refer to Figure 3, the sound signal collecting circuit 10 further includes a second capacitor C2. The second capacitor C2 includes but is not limited to an MLCC multilayer ceramic capacitor. The second capacitor C2 couples the sound signal to the first-stage amplification circuit 121 of the signal amplification circuit 12.

[0067] Please refer to Figure 3, the first-stage amplification circuit 121 includes a second resistor R2, a third resistor R3, a second transistor Q2 (for example, an NPN transistor), a fourth resistor R4, and a fifth resistor R5. One end of the second capacitor C2 is electrically connected to the collector of the first transistor Q1, and the other end of the second capacitor C2, the base of the second transistor Q2, one end of the second resistor R2, and one end of the third resistor R3 are electrically connected to a node. The other end of the second resistor R2 is loaded with a VCC voltage. The third resistor R3 is grounded. The collector of the second transistor Q2 is electrically connected to a VCC voltage line through the fourth resistor R4, and the emitter of the second transistor Q2 is grounded through the fifth resistor R5. The second transistor Q2 serves as a transistor of the first-stage amplification circuit 121 to perform inverting amplification on the signal. The second resistor R2 and the third resistor R3 serve as resistors to set the static working point of the second transistor Q2. The fifth resistor R5 constitutes an emitter negative feedback resistor to stabilize the static working point of the second transistor Q2. The third resistor R3 provides a reasonable VCE voltage for the second transistor Q2. In other embodiments, the fifth resistor R5 can not be provided. The emitter of the second transistor Q2 is directly grounded.

[0068] Please refer to Figure 3, the signal amplification circuit 12 further includes a second-stage amplification circuit 122. The second-stage amplification circuit 122 is used to perform power amplification on the collected sound signal, so as to push the following transistor to work in a switching state and complete preliminary conversion of the switching signal.

[0069] Referring to Fig. 3, the second-stage amplification circuit 122 includes a third capacitor C3. The third capacitor C3 includes, but is not limited to, an MLCC multi-layer ceramic coupling capacitor. The second-stage amplification circuit 122 includes a third transistor Q3 and a fourth transistor Q4. The third transistor Q3 is an NPN transistor. The fourth transistor Q4 is a PNP transistor.

[0070] One end of the third capacitor C3 is electrically connected to the collector of the second transistor Q2. The other end of the third capacitor C3 is electrically connected to the base of the third transistor Q3 and the base of the fourth transistor Q4. The third transistor Q3 and the fourth transistor Q4 are connected in series between the VCC voltage line and the reference ground.

[0071] The third transistor Q3 and the fourth transistor Q4 form a power amplification stage to power amplify the weak signal that has been preliminarily amplified.

[0072] Referring to Fig. 3, the signal conversion circuit 13 includes a fifth transistor Q5 and a sixth resistor R6. The fifth transistor Q5 is an NPN transistor. The base of the fifth transistor Q5 is electrically connected between the third transistor Q3 and the fourth transistor Q4. The collector and the emitter of the fifth transistor Q5 are electrically connected to the sixth resistor R6 and the reference ground, respectively.

[0073] The amplified power signal drives the fifth transistor Q5. The sixth resistor R6 is a pull-up resistor of the fifth transistor Q5 and functions as a pull-up. When the fifth transistor Q5 is not turned on, the collector potential of the fifth transistor Q5 is pulled up to the power supply voltage. When the fifth transistor Q5 is turned on, the pull-up isolation of the sixth resistor R6 allows the collector of the fifth transistor Q5 to be pulled down to the GND ground, thereby completing the preliminary conversion of the sound analog signal to the switching signal. The switching signal is the signal output from the collector of the fifth transistor Q5. The signal conversion circuit 13 outputs a low-level pulse group.

[0074] Referring to FIG. 3, the sound signal acquisition circuit 10 further comprises a high-level pulse output circuit 14, which is configured to output the sound-controlled switch signal by shaping the preliminary converted switch signal through a comparator. The high-level pulse output circuit 14 comprises a seventh resistor R7, an eighth resistor R8, and a comparator 141. The seventh resistor R7 and the eighth resistor R8 are connected in series between a VCC voltage line and a reference ground, forming a reference voltage circuit. The positive input of the comparator 141 is provided with a reference power supply of VCC*R8 / (R8+R7). The collector of the fifth transistor Q5 is connected to the reverse input of the comparator 141, and the switch signal output by the collector of the fifth transistor Q5 is compared with the reference voltage. When there is no switch signal, i.e., the input is high (no sound input), the reverse input is VCC, and the switch comparator 141 outputs 0, i.e., low level. When there is sound and the sound signal is less than VCC*R8 / (R8+R7), a high-level switch signal is output. By adjusting the resistance values of the seventh resistor R7 and the eighth resistor R8, the high-level output duration of the output high-level pulse width can be adjusted, forming the aforementioned sound-controlled command.

[0075] In an alternative embodiment, referring to FIG. 4, the sound signal acquisition circuit 10 can not comprise the aforementioned high-level pulse output circuit 14, but directly output a low-level pulse signal (sound-controlled switch signal). The sound-controlled command output by the sound signal acquisition circuit 10 is input through the IO port (the aforementioned pin terminal) of the single-chip microcomputer, and a low-level pulse signal is detected as a sound input. The IO port receives the low-level pulse signal as a sound signal is acquired, and then judges the sound signal. The sound signal includes, but is not limited to, a sound of gently tapping the atomization device 1000 with a hand or other small objects. Each tap (or knock) obtains a group of low-level pulse groups, and the interval between the rising edge of the first negative pulse and the rising edge of the last negative pulse is within 1 ms to 250 ms. When a low-level pulse group is continuously acquired within a certain time and meets the corresponding working state switching condition, the working state switching of the atomization device 1000 can be performed.

[0076] For example, when a negative pulse group meeting the child lock requirement is continuously acquired within a certain time, the child lock is opened or closed, thereby prohibiting children or minors from inhaling the atomization device 1000. The sound signal acquisition circuit 10 can form a sound-controlled switch.

[0077] In the application scenario of the sound-controlled child lock, the sound-controlled switch outputs a low-level pulse signal as an effective signal. In the starting or standby state of the atomization device 1000, the IO port of the single-chip microcomputer detects N groups of low-level pulse groups within N seconds, triggering the child lock function: specifically, opening or closing the child lock. The N seconds and the N groups of low-level pulse groups are freely definable and can be set to a certain specific value and not changed thereafter.

[0078] Meanwhile, the atomization device 1000 can also be switched on and off and its power can be adjusted through the sound control switch. For example, if X groups of low-level pulse groups are detected within X seconds, the atomization device 1000 is triggered to be switched on or off, wherein X seconds and X groups of low-level pulse groups can be freely defined and can be set to a specific value and then remain unchanged.

[0079] Optionally, referring to FIG. 5, the atomization device 1000 further comprises an atomization control circuit 30 and an atomization wire 40 electrically connected to the atomization control circuit 30.

[0080] The atomization control circuit 30 is electrically connected to the sound control instruction processing circuit 20, i.e., another pin terminal of the single-chip microcomputer.

[0081] Referring to FIG. 6, the sound control instruction processing circuit 20 in the single-chip microcomputer 700 is also used to form an atomization control signal. The atomization control signal is used to control the atomization control circuit 30 to drive the atomization wire 40 to heat.

[0082] The atomization control circuit 30 is described below in combination with the accompanying drawings. Of course, the atomization control circuit 30 includes but is not limited to the following embodiments.

[0083] Referring to FIG. 7, FIG. 7 is a circuit block diagram of an atomization control circuit according to an embodiment of the present application. As shown in FIG. 7, the atomization control circuit 30 comprises a control unit 31 and a voltage stabilizing output unit 32. The control unit 31 comprises a switch, and the voltage stabilizing output unit 32 comprises an energy storage element. The control unit 31 is used to be connected to the battery and the single-chip microcomputer 700 to receive an input voltage input by the battery and a switch control signal output by the single-chip microcomputer 700, and to control the switch according to the input voltage and the switch control signal. The voltage stabilizing output unit 32 is connected to the control unit 31. The voltage stabilizing output unit 32 charges and discharges the energy storage element according to the state of the switch to output a constant output voltage, thereby avoiding the problem of low output voltage caused by low battery voltage, and outputting the constant output voltage to the atomization wire 40 to heat the atomization wire 40, thereby ensuring good atomization taste.

[0084] Please continue to refer to FIG. 7, the control unit 31 includes a first control unit 311 and a second control unit 312, the first control unit 311 and the second control unit 312 are connected with the voltage stabilizing output unit 32. The switch includes a high side switch and a low side switch. Specifically, the first control unit 311 is used to be connected with the battery and the single-chip microcomputer 700 to receive the input voltage and the switch control signal, and to control the high side switch according to the input voltage and the switch control signal to realize charging the energy storage element in the voltage stabilizing output unit 32; the second control unit 312 is used to be connected with the single-chip microcomputer 700 to receive the switch control signal, and to control the low side switch according to the switch control signal to realize discharging the energy storage element in the voltage stabilizing output unit 32. More specifically, when the switch control signal is a low level voltage, the first control unit 311 is opened and the second control unit 312 is closed, the input voltage input by the battery is used to charge the energy storage element in the voltage stabilizing output unit 32; when the switch control signal is a high level voltage, the first control unit 311 is closed and the second control unit 312 is opened, the energy storage element in the voltage stabilizing output unit 32 is discharged through the second control unit 312, thereby ensuring that the voltage stabilizing output unit 32 outputs a constant output voltage.

[0085] Referring to FIG. 8, FIG. 8 is a circuit topology diagram of a first atomization control circuit 30 according to an embodiment of the present application. As shown in FIG. 8, the first control unit 311 includes the high-side switch, a ninth resistor R9, and a tenth resistor R10. The high-side switch is a PMOS transistor Q6. It should be noted that the ninth resistor R9 and the tenth resistor R10 are connected in series, and the resistance value of the tenth resistor R10 is greater than the resistance value of the ninth resistor R9. In this embodiment, the resistance value of the tenth resistor R10 is any value between 1000 ohms and 10000 ohms, and the resistance value of the ninth resistor R9 is any value between 10 ohms and 100 ohms. In this embodiment, the resistance value of the ninth resistor R9 is 50 ohms, and the resistance value of the tenth resistor R10 is 1000 ohms. In other embodiments, the resistance values of the ninth resistor R9 and the tenth resistor R10 can be other values. It should also be noted that, in this embodiment, the conduction voltage of the PMOS transistor Q6 is 2.5V. In other embodiments, a PMOS transistor Q6 with a conduction voltage of another value can be selected according to requirements. The connection relationship among the PMOS transistor Q6, the ninth resistor R9, and the tenth resistor R10 is as follows: the source of the PMOS transistor Q6 is connected to the battery to receive the input voltage, the drain of the PMOS transistor Q6 is connected to the voltage stabilizing output unit 32, and the gate of the PMOS transistor Q6 is connected to the other end of the ninth resistor R9.

The two ends of the sealing sleeve 400 abut against the inner surface of the side wall of the housing 200 and the support plate 300, respectively, and seal the periphery of the sound collecting element 11. The inner surface of the side wall of the housing 200, the sealing sleeve 400, and the support plate 300 form a sound cavity 510 for collecting sound signals, which is used to enhance the sound signals collected by the sound collecting element 11.

Optionally, referring to FIG. 12a, the shell 200 can not have a hole communicating with the sound chamber 510 to prevent dust from entering the main machine.

In other embodiments, referring to FIG. 12b, the shell 200 can have a through hole 520 communicating with the sound chamber 510.

[0106] Referring to FIGS. 11, 12a and 12b, the atomization device 1000 further includes an airflow collecting element 610. The airflow collecting element 610 is arranged in an airflow chamber of the shell 200. The airflow collecting element 610 is used to collect a puffing signal to trigger the atomization control circuit 30 to control the heating of the atomization wire 40. The airflow chamber and the sound chamber 510 are arranged independently and separately. The position of the airflow chamber is not specifically limited in this embodiment, and only one example is shown in the figure. It can also be located at other positions.

[0107] The atomization device 1000 provided in the present application is structurally designed with two chambers (the sound chamber 510 and the airflow chamber). One chamber is arranged with an airflow collecting microphone, and the other chamber is arranged with an acoustic microphone. The airflow collecting microphone can collect a puffing signal through an airway, and the acoustic microphone can collect a sound signal generated by slightly tapping the atomization device 1000 in cooperation with the internal cavity and the circuit part to realize a sound control child lock function, or other functions such as sound control power-on, sound control power-off, sound control power adjustment, etc.

The display screen can display the working state of the atomization device 1000, such as the unlocking / locking state, the power-on / power-off state, the power increase / power decrease state, etc.

[0109] Referring to FIG. 13, and in combination with FIGS. 1 to 12b, the present application further provides a sound control method of the atomization device 1000. The sound control method can be applied to the single-chip microcomputer 700 described above. The sound control method includes but is not limited to the following steps.

[0110] S100: receiving a sound control instruction when the atomization device 1000 is in a target state.

[0111] The sound control instruction is a digital pulse signal, which can also be referred to as a sound control switch signal. When the sound control instruction is a positive pulse, one high-level pulse (or pulse group) represents receiving one sound signal, and one low-level pulse (or pulse group) represents no sound signal.

[0112] When the sound control instruction is a negative pulse, one low-level pulse (or pulse group) represents receiving one sound signal, and one high-level pulse (or pulse group) represents no sound signal.

[0113] The target state includes but is not limited to a boot state, a shutdown state, a power increase, a power decrease, an open child lock state, an upper child lock state, etc.

[0114] S200: Determine whether the sound control instruction meets the condition of triggering the atomization device 1000 to switch the working state.

[0115] Specifically, the single-chip microcomputer 700 pre-stores a preset instruction, for example, the number of pulse groups in a unit time is n. The sound control instruction is compared with the preset instruction to determine whether the number of pulse groups of the sound control instruction in a unit time is n.

[0116] S300: If yes, the atomization device 1000 is triggered to switch the working state.

[0117] If it is determined that the number of pulse groups of the sound control instruction in a unit time is n, and the sound control instruction matches the preset instruction, it indicates that the working state switching can be performed, and then a corresponding trigger signal (corresponding to the lock control signal, the unlock control signal, the power increase signal, and the power decrease signal in the subsequent) is formed to trigger the atomization device 1000 to switch the working state.

[0118] The switched working state includes but is not limited to the switching of the unlock and the lock, or the switching of the boot and the shutdown, or the switching of the power increase or the power decrease, etc. Therefore, the target working state includes but is not limited to the unlock state, the lock state, the boot state, the shutdown state, the power increase, the power decrease, etc.

[0119] If no, the atomization device 1000 is not triggered to switch the working state.

[0120] If it is determined that the number of pulse groups of the sound control instruction in a unit time is not n, and the sound control instruction does not match the preset instruction, the working state switching is not performed.

[0121] Wherein, the target state is different according to different switching working states, which will be described in detail later. In this embodiment, the sound control instruction processing circuit 20 judges whether the sound control instruction meets the condition of triggering the atomization device 1000 to switch the working state according to the current target state of the atomization device 1000 and whether the received sound control instruction is the target sound control instruction corresponding to the switching target working state, and further judges whether to switch to the target working state according to the judgment.

[0122] The sound control method of the atomization device 1000 provided in the present application receives a sound control instruction when the atomization device 1000 is in a target state, judges whether the sound control instruction meets the condition of triggering the atomization device 1000 to switch the working state, and if so, triggers the atomization device 1000 to switch the working state. On the one hand, the sound control method does not need to set a switching switch key on the atomization device 1000, and can be compatible with the appearance consistency of the atomization device 1000. On the other hand, the way of triggering the atomization device 1000 to switch the working state by the sound control instruction is relatively novel and simple, which improves the simplicity of user operation.

[0123] Wherein, the working state can be the switching of the child lock unlocking and locking state. In the atomization device 1000, the regulatory agency proposes that the atomization device 1000 and the system must adopt the child lock function. In the present application, the atomization device 1000 switches the child lock unlocking and locking state by sound control, which meets the regulatory requirements. The child lock function needs to be hidden and has no external identification and logo, and the locking and unlocking of the child lock is stable and reliable, good experience and new experience.

[0124] When the atomization device 1000 is in the power-on or standby state, the sound signal is obtained by collecting the sound generated by slightly tapping the atomization device 1000 through the acoustic ECM, and then the sound signal is processed into a pulse group signal to form a sound instruction.

[0125] The single-chip microcomputer 700 processes the pulse group signal to realize the child lock locking and unlocking function.

[0126] At the same time, the atomization device 1000 can also be switched on or off by collecting the slight tapping of the atomization device 1000 by hand or other small devices through a similar method, and the entire atomization device 1000 cannot see the mechanical switch, which increases the beauty and novelty experience.

[0127] Please refer to FIG. 14, in an alternative embodiment, the target state is the power-on state or the standby wake-up state.

[0129] S210: Determine whether the sound control instruction meets the condition of triggering the atomization device 1000 to switch to the unlocking state in which the atomization can be performed or the locking state in which the atomization cannot be performed.

[0130] Specifically, the sound control instruction for triggering the atomization device 1000 to switch to the unlocking state in which the atomization can be performed or the locking state in which the atomization cannot be performed includes but is not limited to having N pulse groups in n seconds. When the single-chip microcomputer 700 determines that the received sound control instruction has N pulse groups in n seconds, the switching between the unlocking state and the locking state can be performed.

[0131] Optionally, when the atomization device 1000 is in the unlocking state and the sound control instruction meets the unlocking / locking switching condition, the atomization device 1000 switches to the locking state, for example, the child lock closed state.

[0132] Optionally, when the atomization device 1000 is in the locking state and the sound control instruction meets the unlocking / locking switching condition, the atomization device 1000 switches to the unlocking state, for example, the child lock opened state.

[0133] Optionally, S210: Determine whether the sound control instruction meets the condition of triggering the atomization device 1000 to switch to the unlocking state in which the atomization can be performed or the locking state in which the atomization cannot be performed, includes but is not limited to the following steps.

[0134] S211: Determine whether the number of sound sub-signals of the sound control instruction in the preset time period is a target number.

[0135] The sound sub-signal is a pulse group. The sound sub-signal can be a low-level pulse group or a high-level pulse group.

[0136] Specifically, the sound control instruction for triggering the atomization device 1000 to switch to the unlocking state in which the atomization can be performed or the locking state in which the atomization cannot be performed includes but is not limited to having N pulse groups in n seconds. The target number is N. When the single-chip microcomputer 700 determines that the received sound control instruction has the target number (N) of sound sub-signals in the preset time period (n seconds), the switching between the unlocking state and the locking state can be performed.

[0137] S212: If the number of sound sub-signals of the sound control instruction in the preset time period is the target number, it is determined that the sound control instruction meets the condition of triggering the atomization device 1000 to switch to the unlocking state in which the atomization can be performed or the locking state in which the atomization cannot be performed.

[0139] Optionally, when the atomization device 1000 is in the unlocking state, and the number of sound sub-signals of the sound control instruction within the preset time period (n seconds) is the target number (N), the atomization device 1000 switches to the locking state, for example, the child lock closed state.

[0140] Optionally, when the atomization device 1000 is in the locking state, and the number of sound sub-signals of the sound control instruction within the preset time period (n seconds) is the target number (N), the atomization device 1000 switches to the unlocking state, for example, the child lock open state.
