[0061] Currently, the microphone is a key component of electronic atomization products, and its operational reliability determines product quality. In current product designs, the microphone power supply signal is directly connected to the positive terminal voltage of the battery cell through a 10-100 ohm resistor, lacking necessary control over the microphone power supply. Due to the internal structural characteristics of the microphone, the following potential risks exist:
[0062] 1. During production or transportation, the evaporation of e-liquid or the condensation of gas in the microphone cavity can cause deformation of the microphone diaphragm, which can easily lead to false triggering of the microphone and thus cause the product to start automatically.
[0063] 2. On the printed circuit board (PCB) of electronic atomizing products, the power pin and ground pin of the microphone are close to each other. When e-liquid or droplets accumulate on the microphone PCB, a short circuit path can easily be formed here, causing the battery to discharge. This results in the product being unable to be used normally due to low power in a short period of time, affecting the user experience.
[0064] This application provides an electronic atomizing device and a control method for the electronic atomizing device, which can reduce the adverse effects of the electronic atomizing device starting up on its own under abnormal conditions, reduce quality risks, and improve user experience.
[0065] Figure 1 This is an optional structural diagram of the electronic atomizing device provided in the embodiments of this application. For example... Figure 1 As shown, the electronic atomizing device 1 includes: an airflow sensor 10, a control module 11, and a heating module 12. The control module 11 is connected to both the airflow sensor 10 and the heating module 12.
[0066] The airflow sensor 10 is used to generate a suction signal characterizing the user's suction behavior by sensing airflow. The heating module 12 is used to heat the substrate to be atomized. The control module 11 is used to detect the signal from the airflow sensor 10. If the number of suction signals detected within a preset time period is greater than or equal to a preset threshold, the heating module 12 is disabled.
[0067] In this embodiment, the airflow sensor 10 generates and outputs a suction signal characterizing the user's inhalation by sensing the airflow generated when the user inhales. The number of suction signals characterizes the number of inhalations sensed by the user. The control module 11 detects the suction signal generated by the airflow sensor and, based on the suction signal, controls whether to activate the heating module 12 to heat the atomization matrix to atomize it.
[0068] In some embodiments, the airflow sensor 10 may include the microphone in the electronic atomizing device 1. The control module 11 may include the processor in the electronic atomizing device 1, such as a microcontroller unit (MCU), the heating module 12 may include the atomizer in the electronic atomizing device 1, and the atomizing substrate may include a liquid substrate or a solid substrate. For example, the liquid substrate may include drugs or other substances such as e-liquid, etc. The specific selection is based on the actual situation, and the embodiments of this application are not limited thereto.
[0069] In this embodiment, the preset time length and preset number threshold can be customized according to the actual situation. For example, the preset time length can be 500ms and the preset number threshold can be 5 times. If the airflow sensor 10 generates 5 suction signals within 500ms, it indicates that it does not conform to the user's reasonable suction behavior and can be considered as an abnormal situation that is falsely triggered. The heating module 12 is then controlled to disable heating.
[0070] In some embodiments, the electronic atomizing device may further include a storage module. The storage module stores executable instructions, and the control module 11 implements a control method for the electronic atomizing device by executing the executable instructions stored in the memory.
[0071] In some embodiments, different types of airflow sensors 10 generate different types of suction signals. In actual use, suction signals of the corresponding signal type can be detected according to the type of airflow sensor 10. The specific selection is made according to the actual situation, and this application embodiment does not limit it.
[0072] Understandably, the control module can determine whether the airflow sensor has been falsely triggered by detecting the number of suction signals within a preset time period when the airflow sensor generates a suction signal. If an abnormal number of suction signals is detected, it indicates that the user's suction behavior is not normal and is considered a false trigger. In this case, the heating module is disabled to prevent it from activating due to abnormal self-starting, thereby reducing abnormal power and substrate consumption, lowering safety risks, and extending the device's lifespan. Therefore, this reduces the adverse effects of self-starting of the electronic atomizing device in abnormal situations, lowers quality risks, and improves the user experience.
[0073] In some embodiments, the airflow sensor may include any one of a switch-type airflow sensor, a capacitive airflow sensor, and a resistive airflow sensor. The switch-type airflow sensor may include both capacitive and resistive switch-type airflow sensors, and the specific selection depends on the actual situation; this application does not limit the choice.
[0074] In some embodiments, if the number of occurrences of any of the following conditions within a preset time period is greater than or equal to a preset threshold, the heating module is disabled:
[0075] The switch-type airflow sensor outputs a high-level signal;
[0076] The frequency of the signal output by the capacitive airflow sensor exceeds the preset trigger frequency range;
[0077] The resistive airflow sensor outputs a high-level signal, or the analog-to-digital conversion sample value output by the resistive airflow sensor is greater than or equal to a preset trigger sampling threshold.
[0078] The on / off airflow sensor converts the airflow pressure signal into an electrical signal. For example, when the sensed airflow pressure exceeds a preset pressure threshold (e.g., 200 Pa), it outputs a high-level signal, which characterizes the suction signal. If the control module 11 detects that the number of times the on / off airflow sensor outputs a high-level signal within a preset time period is greater than or equal to a preset threshold, it indicates that the suction signal emitted by the on / off airflow sensor is too frequent and does not conform to the user's normal suction behavior. The on / off airflow sensor may be in an abnormal state of being falsely triggered. In this case, the control module 11 controls the heating module 12 to shut down, prohibiting heating to reduce the adverse effects of false triggering.
[0079] The capacitive airflow sensor utilizes airflow generated by inhalation or exhalation to cause deformation of a conductive film, thereby altering the distance between the film and the electrode, resulting in a change in capacitance within the sensor, and consequently, a change in the charging and discharging frequency. For example, in a static state without suction, the charging and discharging frequency of the capacitive airflow sensor is 1000 Hz. When airflow changes cause a change in capacitance, the charging and discharging frequency also changes, for example, to 970 Hz or 1030 Hz. In some embodiments, a preset trigger frequency range can be set by increasing and / or decreasing the static charging and discharging frequency of the capacitive airflow sensor in a static state without suction. For example, the static charging and discharging frequency can be increased and / or decreased by 3% to obtain the preset trigger frequency range. Thus, when the charging and discharging frequency of the capacitive airflow sensor exceeds the preset trigger frequency range, for example, exceeding or falling below a preset trigger frequency threshold, it can be considered that the amount of airflow change in the capacitive airflow sensor has significantly changed, equivalent to generating a suction signal. If the control module 11 detects that the charging and discharging frequency of the capacitive airflow sensor exceeds the preset trigger frequency range more than or equal to a preset threshold number of times within a preset time period, it indicates that the suction signal emitted by the capacitive airflow sensor is too frequent and does not conform to the user's normal suction behavior. The switch-type airflow sensor may be in an abnormal state of being falsely triggered. At this time, the control module 11 controls the heating module 12 to shut down and prohibit heating to reduce the adverse effects of false triggering.
[0080] The resistive airflow sensor converts sensed airflow changes into an analog voltage signal using the principle of resistive voltage division. An analog-to-digital converter (ADC) samples this analog voltage signal, outputting either the ADC sampled value or a quantized level signal. The high-level signal output by the resistive airflow sensor, or the ADC sampled value greater than or equal to a preset trigger sampling threshold, characterizes the suction signal. If, within a preset time period, the resistive airflow sensor outputs a high-level signal greater than or equal to a preset number of times, or if the ADC sampled value output by the resistive airflow sensor is detected to be greater than or equal to the preset trigger sampling threshold a number of times, it indicates that the suction signal emitted by the resistive airflow sensor is too frequent and does not conform to normal user suction behavior. The resistive airflow sensor may be in an abnormal state of being falsely triggered. In this case, the control module 11 controls the heating module 12 to shut down, prohibiting heating to reduce the adverse effects of false triggering.
[0081] Understandably, the control module can detect different types of suction signals from different airflow sensors to determine if the airflow sensor has been falsely triggered. If an abnormal number of suction signals are detected within a preset time period, the heating module is disabled to prevent abnormal self-starting from triggering abnormal operation of the heating module. This reduces abnormal power and substrate consumption, lowers safety risks, and extends the lifespan of the device. Therefore, it reduces the adverse effects of self-starting of the electronic atomization device under abnormal conditions, lowers quality risks, and improves the user experience.
[0082] In some embodiments, such as Figure 2 As shown, the electronic atomizing device 1 also includes a display module 13. The display module 13 is connected to the control module 11. When the heating module 12 is disabled, the control module 11 controls the display module 13 to display a prompt message.
[0083] For example, the display module 13 may include a light-emitting diode (LED) lamp or an LED electronic screen. When the heating module 12 is disabled, the LED lamp is controlled to flash in a preset prompt manner, or the LED electronic screen is controlled to display characters and / or patterns with preset content to prompt the user with a prompt message indicating that the heating module 12 is disabled.
[0084] Understandably, displaying a prompt message when the heating module is disabled allows users to be promptly informed of the module's status, thus improving the user experience.
[0085] In some embodiments, after disabling the heating module 12, the control module 11 can also determine whether to lift the heating restriction and enable the heating module 12 to heat the atomized substrate by signal detection. The heating module 12 is enabled upon detecting a preset activation signal.
[0086] In some embodiments, the preset activation signal includes at least one of the following: a charger access signal, a cartridge insertion / removal signal exceeding a preset insertion / removal number threshold, and a preset button signal exceeding a preset number of consecutive presses.
[0087] Specifically, if the control module 11 detects any one of the following signals: a charger connection signal, a cartridge insertion / removal signal exceeding a preset insertion / removal number threshold, or a preset button press signal exceeding a preset number of consecutive presses, it indicates that the user has actively operated the system, intending to restore or activate the heating function of the heating module 12. At this time, the control module 11 releases the heating restriction on the heating module 12 and enables the heating module 12 to heat the atomization substrate.
[0088] Understandably, resuming heating of the heating module 12 upon detecting an activation signal improves control flexibility and reliability, and enhances the user experience.
[0089] In some embodiments, the electronic atomizing device may further include a power module 14 and a button module 15. A control module 11 is connected to the button module 15; the control module 11 is connected between the power module 14 and the airflow sensor 10. Figure 2 For example, the structure of an electronic atomizing device can be as follows: Figure 3 As shown. It should be noted that it can also be based on... Figure 1 The structure yields an electronic atomizing device comprising a power module 14 and a button module 15.
[0090] like Figure 3 As shown, the power module 14 is electrically connected to the airflow sensor 10, control module 11, heating module 12, and display module 13, and is used to supply power to the airflow sensor 10, control module 11, heating module 12, and display module 13. The power module 14 includes, but is not limited to, devices capable of providing electrical energy such as batteries. Batteries may include disposable batteries or rechargeable batteries. It should be noted that in some embodiments, the power module 14 can supply power to the storage module in the electronic atomization device, or other power sources can supply power to the storage module; this application does not limit this.
[0091] In some embodiments, the button module 15 is used to generate button information based on the user's button operation; the control module 11 is also used to: acquire the button information of the button module 15; and control the power supply module 14 to supply power to the airflow sensor 10 based on the button information, that is, control the power supply module 14 to power on or power off the airflow sensor 10.
[0092] In some embodiments, when the button information indicates that the device is off, the control power module stops supplying power to the airflow sensor; when the button information indicates that the device is on, the control power module supplies power to the airflow sensor.
[0093] In some embodiments, the control module and the power supply module can be implemented in the same integrated chip, and the power supply module provides power to the airflow sensor is controlled by an algorithm within the integrated chip. For example, as shown... Figure 4 As shown, for capacitive airflow sensors, such as capacitive microphones, the power supply module 14 and control module 11 are integrated into the same integrated chip U2. The control module in integrated chip U2, upon receiving a power-on button signal, controls the power supply module 14 to supply power to the capacitive microphone U1. After the capacitive microphone U1 is started, it detects the suction signal generated by the capacitive microphone U1 through the MIC1 port. If, within a preset time period, the number of times the signal frequency output by the capacitive airflow sensor exceeds a preset trigger frequency range is greater than or equal to a preset threshold, the heating module (not shown) is controlled to stop heating. Upon receiving a power-off button signal, the power supply module 14 is controlled to stop supplying power to the capacitive microphone U1.
[0094] In some embodiments, the power supply module can be controlled to power the airflow sensor by a single I / O push-pull control method of the MCU, or it can be controlled by a dual I / O combination control method. The specific installation should be carried out according to the actual situation, and the embodiments in this community are not limited.
[0095] In some embodiments, the control module includes a control unit and a switching unit; a first end of the switching unit is connected to the controller; a second end of the switching unit is connected to the power module; and a third end of the switching unit is connected to an airflow sensor.
[0096] The control unit is used to send a connection signal or a disconnect signal to the switch unit according to the button information, so as to control the power supply module to supply power to the airflow sensor by connecting or disconnecting the switch unit.
[0097] For example, the control unit may include an MCU, and the switching unit may include a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), or simply a MOS transistor.
[0098] In other words, the power supply module can be controlled to turn the airflow sensor on and off by using an MCU in conjunction with a switching circuit.
[0099] For example, such as Figure 5As shown, the switching unit can be a MOSFET Q1. The first terminal of Q1 is connected to the control unit (not shown) via the MIC_EN1 port, the second terminal of Q1 is connected to the power module VBAT1, and the third terminal of Q1 is connected to the switching airflow sensor via resistor R7. Figure 5 The control unit sends a connection or disconnect signal to the switch unit Q1 via the MIC_EN1 port, controlling the switch unit Q1 to connect VBAT1 and U3, or to disconnect VBAT1 and U3, thereby controlling VBAT1 to supply power to the switch unit U3. When the switch unit U3 is powered on, the control unit detects the signal generated by the switch unit U3 via the MIC2 port. If the number of high-level signal occurrences detected within a preset time period is greater than or equal to a preset threshold, the control unit controls the heating module (not shown in the figure) to stop heating.
[0100] For example, such as Figure 6 As shown, the switching unit can be a MOSFET Q2. The first terminal of Q2 is connected to the control unit (not shown) via the MIC_EN2 port, the second terminal of Q2 is connected to the power module VBAT2, and the third terminal of Q2 is connected to a capacitive airflow sensor via resistor R7. Figure 6 The discrete capacitor microphone consists of U4 and U5. The control unit sends a connection or disconnect signal to the switching unit Q2 through the MIC_EN2 port, controlling the switching unit Q2 to connect VBAT2 and the discrete capacitor microphone, or to disconnect VBAT2 and the discrete capacitor microphone, thereby controlling the power supply of VBAT2 to the discrete capacitor microphone. When the discrete capacitor microphone is powered on and started, the control unit detects the signal generated by the discrete capacitor microphone through the MIC3 port. If the number of times the charging and discharging frequency exceeds the preset trigger frequency range within a preset time length is greater than or equal to a preset threshold number, the control unit controls the heating module (not shown in the figure) to stop heating.
[0101] For example, such as Figure 7 As shown, the switching unit can be a MOSFET Q3. The first terminal of Q3 is connected to the control unit (not shown) via the MIC_EN3 port, the second terminal of Q3 is connected to the power module VBAT3, and the third terminal of Q3 is connected to a resistive airflow sensor, as shown below. Figure 7The resistor is composed of R1, R2, and C1. R1 is the sensing resistor. The control unit sends a connection or disconnect signal to the switching unit Q3 via the MIC_EN3 port, controlling the switching unit Q3 to connect VBAT3 and the resistor, or to disconnect VBAT3 and the resistor, thereby controlling VBAT3 to supply power to the resistor. When the resistor is powered on, the control unit detects the signal generated by the resistor via the MIC4 port. If the number of high-level signal occurrences within a preset time period is greater than or equal to a preset threshold, or if the number of analog-to-digital conversion sample values generated by the resistive airflow sensor greater than or equal to a preset trigger sampling threshold is greater than or equal to a preset threshold, the control unit stops heating the heating module (not shown in the diagram).
[0102] In some embodiments, a resistor may also be connected between the first and second terminals of the switching unit, such as... Figure 5-7 The resistor R10 is shown in the figure.
[0103] In some embodiments, the connection or disconnection signal sent by the control unit to the switching unit can be a PMOS high-side signal, an NMOS low-side signal, or a control signal of a combination logic of PMOS and NMOS. The specific selection is made according to the actual situation, and the embodiments of this application do not limit it.
[0104] Understandably, controlling the power supply to the airflow sensor via button input enables power management of the airflow sensor. This prevents the airflow sensor from being accidentally triggered while powered on, thus avoiding abnormal self-starting of the e-cigarette device. This effectively reduces the number of false triggers, thereby reducing abnormal power and substrate consumption, lowering safety risks, and extending the device's lifespan. Therefore, it reduces the adverse effects of self-starting of the e-cigarette device under abnormal conditions, lowers quality risks, and improves the user experience.
[0105] This application also provides a control method for an electronic atomizing device, applied to the control module of any of the electronic atomizing devices described above. The control method for the electronic atomizing device includes:

[0109] The charging / discharging frequency signal of the capacitive airflow sensor exceeds the preset trigger frequency range;

[0121] When the button information indicates that the device is powered on, the power module is controlled to supply power to the airflow sensor.
[0122] In some embodiments, controlling the power module to stop supplying power to the airflow sensor includes:
[0123] A disconnect signal is sent to the switching unit to control the power module to stop supplying power to the airflow sensor by disconnecting the switching unit.
[0124] In some embodiments, controlling the power module to supply power to the airflow sensor includes:

[0126] It should be noted that the descriptions of the above method embodiments are similar to those of the above circuit embodiments, and have similar beneficial effects. For technical details not disclosed in the method embodiments of this application, please refer to the descriptions of the circuit embodiments of this application for understanding.
[0127] Below, for reference Figure 8 This application introduces a control method for an electronic atomization device applied in a real-world scenario, based on embodiments of the present application.
[0128] like Figure 8 As shown, the control module first judges the button status. If the button information indicates a power-off command, the microphone power is turned off, and sucking is prohibited. If the button information indicates a power-on command, the microphone is powered on and started. After the microphone starts, signal detection is performed to determine whether the microphone has been abnormally triggered and to activate protection. If the number of sucking signals n detected within a preset time length T1 (t≤T1) is greater than or equal to a preset threshold N1 (n≥N1), it is determined that the microphone has been abnormally triggered. The LED flashes 3 times as a prompt to the user, and the heating module's heating is limited. If the number of sucking signals n within the preset time length is less than the preset threshold N1, it means that no abnormality has been detected, and normal sucking logic is followed. The control module continuously monitors the microphone signal. If a preset activation signal is detected while the heating module's heating is limited, it is determined that the activation condition has been met, the heating limitation is lifted, and sucking is allowed.
[0129] It is understood that the control method for the electronic atomizing device provided in this application can identify potential abnormal output signals from the microphone and take corresponding protective measures. Furthermore, it achieves microphone power supply management, effectively reducing power loss caused by microphone malfunctions during production, processing, storage, and product transportation. Thus, through microphone malfunction start-up management and power supply management, the electronic reliability of the product is improved, and quality risks are reduced.
[0130] This application provides a storage medium storing executable instructions, which are used to cause the processor in the electronic atomizing device to execute, thereby implementing the control method of the electronic atomizing device provided in this application.
[0131] In some embodiments of this application, the storage medium may be a memory such as FRAM, ROM, PROM, EPROM, EEPROM, flash memory, magnetic surface memory, optical disk, or CD-ROM; or it may be a device that includes one or any combination of the above-mentioned memories.
[0132] In some embodiments of this application, executable instructions may take the form of programs, software, software modules, scripts, or code, written in any form of programming language (including compiled or interpreted languages, or declarative or procedural languages), and may be deployed in any form, including being deployed as a standalone program or as a module, component, subroutine, or other unit suitable for use in a computing environment.
[0133] As an example, executable instructions may, but do not necessarily, correspond to files in a file system. They may be stored as part of a file that holds other programs or data, for example, in one or more scripts in a Hyper Text Markup Language (HTML) document, in a single file dedicated to the program in question, or in multiple collaborating files (e.g., a file that stores one or more modules, subroutines, or code sections).
[0134] As an example, executable instructions can be deployed to execute on a single computing device, or on multiple computing devices located in one location, or on multiple computing devices distributed across multiple locations and interconnected via a communication network.
[0135] In the embodiments provided in this application, it should be understood that the disclosed circuits, devices, and methods can be implemented in other ways. The embodiments of circuits and devices described above are merely illustrative. For example, the division of units is only a logical functional division, and in actual implementation, there may be other division methods, such as: multiple units or components may be combined, or integrated into another system, or some features may be ignored or not executed. In addition, the coupling, direct coupling, or communication connection between the various components shown or discussed may be through some interfaces, indirect coupling or communication connection of devices or units, and may be electrical, mechanical, or other forms.
[0136] The above description is merely an embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
