[0022] For a thorough understanding of the present application, detailed descriptions of specific structure and steps will be presented in the following description of embodiments. The preferred embodiments of the present application will be described in detail below with reference to the attached drawings.

[0023] Embodiment One The embodiment one provides a working state detection method of an atomization device, as shown in the figure, the atomization device comprises a microphone 10 and a controller 20, when the microphone 10 is started, the microphone 10 outputs a level signal to the controller 10, and the working state detection method is applied to the controller 20, as shown in the figure, the working state detection method comprises: Figure 1 Figure 2 Step S101. When the microphone is detected to be started, the current working state of the atomization device is acquired; Step S102. In the case that the current working state is an empty load state, the working state of the microphone within a first preset time length is monitored; Step S103. If the working state of the microphone within the first preset time length remains unchanged, it is determined that the current working state is an empty load state; Step S104. If the working state of the microphone within the first preset time length changes, it is determined that the empty load state is mis-triggered.

[0024] In step S101, in the working process of the atomization device, the output state of the microphone is detected in real time by the main control chip. When the microphone first outputs a starting signal (for example, a high level), it indicates that the inhalation action may be detected. At this time, whether the atomization device is currently in an effective load connection state is acquired by means of voltage sampling or current detection, and whether it is an empty load state is preliminarily judged. Example: the main control chip samples the output end voltage through an AD converter, and if the AD value is higher than the set threshold, it is judged as a suspected empty load state.

[0025] In step S102, after it is judged as a suspected empty load state, a prompt or an alarm is not immediately issued, but a monitoring period is entered. In the first preset time length (for example, 500 ms), whether the microphone signal remains stable is continuously detected to avoid misjudgment caused by transient disturbance. Example: the microphone output signal is sampled once every 1 ms, and the time of the maintained state is accumulated.

[0026] In step S103, if the signal output by the microphone remains as a high level (or a continuous activation state) within the preset time length, it can be considered that the signal is not caused by external disturbance, but is derived from the real operation of the user, at this time, it is confirmed that the current working state is an empty load state, and a prompt can be given to the user. Example: the microphone continuously outputs a high level signal for more than 500 ms, and it is judged as a real empty load inhalation, and an empty load prompt process is executed.

[0027] ​​In step S104, if the microphone output signal is interrupted (for example, changes from high level to low level) within a preset time length, it indicates that the trigger may be caused by short-time disturbance such as pulling out the atomization component, package extrusion, etc. At this time, it is determined as a false trigger, and the idle load prompt is not performed to avoid misleading the user. Example: any low-level signal is detected within 500 ms monitoring period, and the system cancels the idle load judgment flag.

[0028] The technical effect of the technical scheme provided by the embodiment is that, after detecting the microphone start signal, the current load state of the device and the change of the microphone signal within a preset time length are combined to determine whether the start behavior is a real and effective user operation. Specifically, when the device is in an idle state, if the microphone signal remains unchanged within a preset time length, it is confirmed as an idle trigger; if the signal changes, it can be accurately identified as an abnormal trigger behavior. The state detection method uses the continuity and stability characteristics of the microphone signal, combines with the idle state recognition logic, and effectively distinguishes the trigger caused by the user's real inhalation action from the false trigger caused by air pressure disturbance (such as pulling out the atomization component, transportation extrusion, etc.). Compared with the method of judging only by single signal or instantaneous state in the prior art, the technical scheme introduces a continuity judgment mechanism in the time dimension, which improves the accuracy and robustness of the judgment. Therefore, the technical scheme has the following beneficial technical effects: effectively reducing the false idle load prompt caused by air pressure fluctuation; avoiding the user's misunderstanding of the device abnormality, improving the overall use experience; not relying on additional hardware sensors, and being realized based on the existing microphone signal and the master control chip, having good cost effectiveness and system compatibility; enhancing the system anti-interference ability, improving the intelligent recognition level and reliability of the atomization device.

[0029] As an implementation manner, the detection of the microphone start includes: In the case that the microphone meets the start condition, when the first level signal output by the microphone is received, it is determined that the microphone is started.

[0030] The atomization device is connected with an atomization module, and the start condition is that the atomization module is separated from the atomization device or the air pressure around the microphone changes when the closed space around the microphone is extruded.

[0031] The detection of the microphone start means that when the environment of the microphone (microphone) meets a specific condition and the output signal of the microphone is a first level (for example, low level or high level, which is defined according to the circuit), it is determined that the microphone is triggered. The start condition is a specific environmental state, such as: the atomization module is separated from the atomization device, which may cause the change of the air flow path of the device and cause the air pressure change; the closed space around the microphone is extruded during transportation, and the atomization device is pressed by external force, which causes the air flow or air pressure to be abnormal and causes the microphone to respond. These changes may cause the microphone to output an electrical signal, which is mistakenly identified as user inhalation, and then causes the device to start.

[0032] The technical effect of the embodiment is that by combining the output signal of the microphone with the preset starting condition (such as the separation of the atomization module or the air pressure change caused by transportation extrusion), a comprehensive judgment is made to effectively distinguish the real puffing behavior from the false triggering caused by non-human interference, thereby improving the recognition accuracy of the atomization device in the subsequent idle state, preventing the device from abnormally starting in a non-working state, and improving the reliability, safety and use efficiency of the system.

[0033] As an embodiment, as shown in Figure 3 The current working state of the atomization device is obtained, including: Step S201. Obtain the output voltage of the atomization device. Step S202. Determine the current working state of the atomization device according to the output voltage and the preset threshold.

[0034] In step S201, the premise of this step is that the atomization device is in a state capable of outputting voltage (for example, powered on and in a working preparation state). In this state, the actual voltage value of the output end of the atomization device is sampled and obtained by the detection circuit. The output voltage generally refers to the voltage at the connection to the atomization module or the load, and through the voltage, it can be reflected whether the device has a load or the load state is normal. If there is a load connected and working normally, the output voltage is generally stable in a certain working voltage range; if the output is open or the load is abnormal, the output voltage may be close to the no-load voltage or significantly deviate from the working voltage.

[0035] In step S202, the voltage value obtained in the previous step is compared with the preset voltage threshold. The threshold can be an upper threshold and a lower threshold set by historical experience, which is used to identify whether the device is in an idle, loaded or short-circuit state. The voltage higher than the upper threshold indicates that the load is not connected (idle state), because there is no current output, and the output voltage is close to the no-load voltage; the voltage between the upper threshold and the lower threshold indicates that the load is connected, and there is current output, that is, the atomization module is working; the voltage lower than the lower threshold indicates a short circuit or device failure.

[0036] The technical effect of the embodiment is that by detecting the voltage of the output end of the atomization device and combining the preset threshold for judgment, the current working state of the device, such as idle, loaded or abnormal state, can be quickly and accurately identified, thereby realizing real-time monitoring of the running state of the atomization device and effectively improving the intelligent level and use safety of the device.

[0037] As an embodiment, as shown in Figure 4 According to the output voltage and the preset threshold, the current working state of the atomization device is determined, including: Step S301. The output voltage is analog-to-digital converted to obtain an output voltage sample value; Step S302. When the output voltage sample value is within the preset voltage range and lasts for a second preset duration, it is determined that the current working state is a normal working state. Step S303. When the output voltage sample value is less than the lower limit value of the preset voltage range and lasts for a third preset duration, it is determined that the current working state is a short circuit state. Step S304. When the output voltage sample value is greater than the upper limit value of the preset voltage range and lasts for a fourth preset duration, it is determined that the current working state is an idle state.

[0038] Among them, step S301 is to analog-to-digital convert (ADC) the analog voltage signal of the output end of the atomization device, and convert it into a digital form of voltage sample value for subsequent processing. The sampled voltage value can be used for comparison, judgment, recording, etc. in a digital control system (such as MCU).

[0039] Among them, in step S302, if the sample value is within the voltage range of normal working (for example, 3.3V-4.2V), and this state lasts more than a second preset duration (for example, 100ms or 500ms), it is determined that the atomization device is currently running stably and is in a normal working state. The introduction of the preset duration here is to avoid misjudgment caused by transient fluctuations, such as state switching caused by temporary voltage jump.

[0040] Among them, in step S303, if the sampled voltage value continuously falls below the lower limit value of the normal voltage range (such as below 2V) and remains for a certain time (third preset duration), it is possible that the output end has a short circuit, that is, the output voltage is quickly pulled down. By introducing time judgment, it can avoid misjudgment caused by switch jitter, interference and other transient factors, and ensure that the system only makes a short circuit judgment in stable abnormal conditions.

[0041] Among them, in step S304, if the sample value is higher than the upper limit of the normal voltage range (for example, higher than 4.5V) and lasts more than a fourth preset duration, it is considered that the atomization device is in an idle state. It means that there is no connection to the atomization module or the atomization module does not work normally, resulting in no current flowing in the circuit, and the output voltage is in a suspended state.

[0042] The technical effect of the embodiment is that by analog-to-digital converting the output voltage of the atomization device and combining multi-level voltage threshold and duration judgment, the device can accurately distinguish between normal working, short circuit or idle state, realize high reliable recognition of the device running state, avoid misjudgment and omission, and improve the stability and safety of the system.

[0043] As an example, as Figure 5As shown, the working state detection method specifically includes the following steps: Step S11, detecting that the microphone starts; Step S12, opening the output, and then detecting the voltage value of the output end; Step S13, detecting whether the AD value is greater than 3750 and less than 4060; if yes, executing step S14, otherwise executing step S17; Step S14, increasing the normal output timer T by 1, and clearing the idle load timer S and the short circuit timer D; Step S15, detecting whether T is greater than 10; if yes, executing step S16; otherwise, returning to execute S13; Step S16, considering that the working state is normal puffing, and executing the display of puffing; Step S17, detecting whether the AD value is greater than 4060; if yes, executing step S18, otherwise executing step S21; Step S18, increasing the idle load timer S by 1, and clearing the normal output timer T and the short circuit timer D; Step S19, detecting whether S is greater than 10; if yes, executing step S20, otherwise, returning to execute S13; Step S20, considering that the working state is idle load; Step S21, detecting that the AD value is less than 3750, and considering that the resistance of the smoke cartridge is too small or the working state is short circuit; Step S22, increasing the short circuit timer D by 1, and clearing the normal output timer T and the idle load timer S; Step S23, detecting whether D is greater than 10; if yes, executing step S24, otherwise, returning to execute S13; Step S24, considering that the working state of the smoke cartridge is short circuit.

[0044] As an implementation mode, the working state of the microphone remains unchanged within the first preset time length, including: When the first level signal output by the microphone is continuously received within the first preset time length, it is determined that the working state of the microphone remains unchanged.

[0045] The first level signal refers to a fixed level (e.g., high level) output by the microphone in a certain specific state, which is used to represent the current working state thereof. Generally, the first level signal can represent a state of "external air pressure change". Continuous reception means that the output first level signal of the microphone is continuously collected without change (e.g., from high level to low level) in the entire first preset time length (e.g., 200 ms, 500 ms). If the microphone always outputs the first level signal in the entire time, it indicates that the air pressure disturbance is continuous and may be caused by a real user operation (e.g., inhalation). Therefore, this step is actually a stability determination process, which uses the continuity of the level signal to determine whether it is a real continuous inhalation behavior.

[0046] As an implementation manner, the working state of the microphone changes in the first preset time length. In the first preset time length, when the first level signal output by the microphone is received and changes to a second level signal, it is determined that the working state of the microphone changes.

[0047] The first level signal is high level, which indicates that the microphone detects air flow change or is in a "start" state. The second level signal is low level, which indicates that the air flow has stopped and the microphone is in an "untriggered" state. In the first preset time length (e.g., 500 ms) set by the system, if the output of the microphone changes from high level to low level, it indicates that the signal is a short pulse and does not have continuity. Therefore, the change is determined to be a change in the working state, and it is further determined that the microphone start this time is a false trigger behavior, and the empty load state is not prompted.

[0048] By continuously monitoring whether the output signal of the microphone changes from the first level signal to the second level signal in the first preset time length, the stability and change of the working state of the microphone are accurately identified. When the microphone signal is continuously at the first level in the entire time length, the system can effectively determine that it is a real continuous trigger behavior. When the signal changes in level, it can be quickly identified as a false trigger caused by a short disturbance. This method has the advantages of high judgment accuracy and strong anti-interference ability, effectively reduces the probability of false empty load prompt, and improves the reliability and user experience of the atomization equipment.

[0049] In the above embodiments, when the user performs a normal inhalation operation, the microphone (microphone) will be triggered due to the change of air flow, thereby starting the atomization process. However, it is found in actual use that when the user pulls out the atomization assembly (i.e. the cartridge), the microphone will also be triggered due to the instantaneous flow of air. At the same time, after the pulling action occurs, the device is immediately in an unloaded state, so the system often mistakenly thinks that the user is inhaling in the unloaded state, thereby incorrectly triggering the unloaded alarm prompt. To solve this false triggering problem, the present embodiment provides a working state detection method to distinguish between real inhalation operation and microphone false triggering caused by factors such as cartridge pulling and transportation. The control flow is as follows: 1. First detection stage: when the controller first detects that the microphone outputs a high level signal, it immediately confirms whether the current device is in an unloaded state through voltage sampling or resistance determination, etc. 2. Delay judgment stage: if it is confirmed that the current device is in an unloaded state, the controller will not immediately prompt the unloaded alarm, but will enter a first preset delay time (such as 500 milliseconds) monitoring window. The length of this delay can be adjusted according to the characteristics of the product; 3. Signal stability detection: during this delay time, the controller continuously monitors the output level state of the microphone. If the microphone signal is continuously high level during the entire period, it is determined to be a real unloaded inhalation behavior, and the unloaded alarm prompt is executed. If the microphone signal has been interrupted (i.e. from high level to low level) more than once during the monitoring period, it is considered that the signal is caused by short-time false triggering, and no unloaded prompt is performed; 4. Normal inhalation recognition: if it is judged that the device is normally loaded (i.e. the cartridge is in good contact with the device) at the first time, the system judges that the current operation is a normal inhalation operation, and processes according to the inhalation flow, such as outputting the atomization control signal, displaying the inhalation animation, etc.

[0050] The present embodiment can effectively identify non-inhalation behaviors such as cartridge pulling, transportation and extrusion by combining the continuity monitoring of the microphone signal with the load state recognition, thereby avoiding false alarms caused by short-time air pressure disturbance and improving the judgment accuracy of the device and the user experience.

[0051] As an example, as shown in Figure 6 , Step S31: judge whether it is 1MS, if yes, execute step S32, otherwise return to execute step S31; Step S32: the current total state is unloaded state; Step S33: detect whether the timer A is added to 500MS, if yes, execute step S34, otherwise execute step S35; Step S34: consider normal suction state, execute the display of suction; Step S35: judge whether the microphone signal is high level, yes, then execute step S37, no, then execute step S36; Step S36: A clear, while considering the microphone false touch, do not make any prompt; Step S37: timer A plus 1, return to execute step S31.

[0052] To further improve the recognition accuracy of the atomization device to the false trigger behavior, the present embodiment adds a joint determination mechanism of the air pressure change amplitude ΔP and the duration ΔT on the basis of the prior art scheme, dynamically evaluates the credibility of the microphone start signal, and enhances the distinguishing ability of the false trigger event (such as pulling out the cartridge, transportation and extrusion, etc.) and the real inhalation action. Specifically, the following steps are included: Step S401: collect air pressure change data, when the controller detects that the microphone outputs the first level signal (indicating air flow disturbance), start the air pressure monitoring sub-module, continuously sample the air pressure values collected by the microphone to form a sampling sequence P(t), and the sampling interval can be set to 1ms-5ms; Step S402: calculate the air pressure change amplitude ΔP, within the first preset time length (for example, 500ms), calculate the maximum amplitude ΔP of the air pressure change, that is: ΔP = max(P(t)) - min(P(t)); t ∈ [0, first preset time length] If ΔP is lower than the preset disturbance threshold ΔP (for example, 5Pa-15Pa), it indicates that the air pressure change amplitude is too small to be judged as an effective inhalation action, which may be a slight disturbance such as transportation shaking.

[0053] Step S403: calculate the disturbance duration ΔT, identify the time length ΔT that the air pressure change amplitude exceeds the small disturbance threshold (for example, 3Pa) in the continuous sampling data, if ΔT is less than the set threshold ΔTt (for example, 100ms-200ms), it indicates that the trigger signal does not have enough stability.

[0054] Step S404: credibility joint determination, if ΔP ≥ ΔPt and ΔT ≥ ΔTt are met at the same time, it is determined that the current microphone start is a real inhalation operation, and the device enters the normal smoking control process; if the above conditions are not met, it is determined that the current is a false trigger event, the controller does not execute the idle load prompt, and does not perform atomization output. Example: ΔPt=10Pa; ΔTt=150ms; the first preset time length is 500ms; the sampling frequency is 1kHz. Under this scheme, if the detected air pressure disturbance lasts only 80ms, or the air pressure fluctuation amplitude is only 3Pa, even if the microphone outputs the start signal, it will be identified as a non-real inhalation action by the system and filtered.

[0055] The technical effect of the embodiment is that, unlike the original scheme which only relies on level persistence judgment, the extended scheme establishes a credibility double threshold model from the intensity (ΔP) and persistence (ΔT) of air pressure disturbance, significantly improving the following performance: it can effectively identify air pressure disturbances caused by slight carrying, transportation bumps, etc., reducing false positives; it excludes non-continuous triggers through persistence identification, ensuring user inhalation experience; it is more fault-tolerant to air pressure changes under different user suction and different altitude environments; the method is implemented based on the existing microphone air pressure data collection mechanism, and can be deployed through software upgrade without additional hardware.

[0056] As an embodiment, to further improve the recognition accuracy of the atomization device for false triggering behavior, on the basis of the existing working state detection method, the embodiment introduces a double-channel stability verification mechanism, which enhances the anti-interference ability of the system to unstable triggering signals through the joint determination of the level persistence channel and the continuous sampling judgment channel, effectively avoiding false positives caused by short-term air pressure disturbance or electronic interference.

[0057] In the embodiment, the working state monitoring module not only detects the single level state of the microphone within the first preset time length, but also divides the microphone output signal into two parallel channels for processing: 1. Level persistence channel (first channel): determine whether the microphone continuously outputs the first level signal within the entire first preset time length; 2. Continuous sampling stability channel (second channel): multiple fast sampling of the microphone signal, analysis of the stability and continuity of the sampling results.

[0058] The above two channels need to meet their respective stability conditions at the same time, so as to confirm the real inhalation behavior and further determine the current working state as the empty load state; otherwise, it is determined as an abnormal trigger, and the empty load inhalation is not prompted. The specific execution steps are as follows: Step S501: detecting that the microphone is started, i.e., receiving the first level signal output by the microphone.

[0059] Step S502: enter the first preset time length monitoring window (e.g., 500 ms), and start the double-channel judgment process.

[0060] Step S503: within the entire first preset time length, determine whether the microphone output is always the first level; if there is a level jump (e.g., high→low) at any time, the first channel is determined to be unstable.

[0061] Step S504: In a preset time period, the microphone output level is quickly sampled at a fixed interval (for example, every 1 ms) to form a sample sequence {E1, E2,..., En}; set the sampling number n = 20, count the number of high-level samples N1; if N1≥ M (where M is a stability threshold, for example, M = 16), the second channel is determined to be stable; otherwise, it is determined to be unstable.

[0062] Step S505: Integrate the judgment results of the two channels. If both channels are in a stable state, it is determined that the current microphone output is a real inhalation behavior, and the current working state is an empty load state; otherwise, it is determined to be a false trigger, and the empty load prompt logic is skipped.

[0063] Example: The first preset time length is 500 ms, the sampling interval is 1 ms, the sampling number n is 20, and the high-level determination threshold M is 16 (80%).

[0064] The embodiment introduces a dynamic threshold adaptive judgment mechanism, automatically generates a judgment reference value in the current environment according to the real-time output voltage and air pressure signal when the device starts, and dynamically sets the inhalation recognition threshold combined with the relative change ratio, which can effectively adapt to the use requirements of different user suction differences and high altitude, cold and other extreme environmental conditions, significantly improve the accuracy of working state recognition and the environmental robustness of the system, avoid false positives or missed judgments caused by fixed thresholds, and the scheme can be realized through software on the basis of existing hardware, has good compatibility and cost advantage.

[0065] As an embodiment, the embodiment is used to solve the misjudgment problem caused by fixed threshold setting in the traditional scheme, and improve the recognition accuracy and adaptability of the device under different environmental conditions and individual user differences. In the embodiment, the atomization device includes a microphone and a controller, and the controller is used to execute the working state detection method of the embodiment. The overall process includes the following steps: Step S601: Baseline acquisition stage, when the atomization device is powered on or the atomization module is detected to be replaced, the controller enters a static sampling mode, and in a stable state without inhalation operation, the output end voltage and the microphone air pressure signal are sampled several times, for example, 10 times in succession, and the sampling interval is 10 ms. The controller averages the collected voltage values and air pressure values respectively to obtain the reference voltage value V0 and the reference air pressure value P0 in the current environment, that is:

[0066] Wherein, N is the sampling number.

[0067] Step S602: Dynamic threshold calculation, based on the collected reference value V0 and reference air pressure value P0, the system calculates the dynamic determination threshold according to the preset relative fluctuation tolerance. Taking voltage as an example, set the tolerance coefficient a = 5, then the dynamic determination upper and lower limits of the output voltage are: V LOW = V0×(1-ɑ);V HIGH = V0 ×(1+ɑ) Similarly, for the microphone air pressure signal, set the fluctuation tolerance β (such as 10 Pa), then the dynamic determination threshold is: P thr = P0±β; The dynamic threshold of the above voltage and air pressure can be used to determine the no-load state, normal inhalation or abnormal trigger behavior.

[0068] Step S603: Microphone start detection and real-time signal acquisition, when the controller detects the first level signal output by the microphone (indicating that there may be inhalation action or air pressure disturbance), it immediately starts the state recognition process and collects the current output voltage U and current air pressure value P in real time.

[0069] Step S604: State determination, the controller compares the current sampling value with the dynamic threshold to determine the current working state: if the current output voltage U>V HIGH , or the current air pressure value satisfies P<P0-β, it is determined as a suspected no-load inhalation state; if the current output voltage is in the interval

V LOW , V HIGH

[0070] To improve the stability and anti-interference ability of the judgment, the system can also continuously sample the above voltage and air pressure signals within a first preset time (such as 500 ms), and further confirm the state result through sliding window averaging or trend judgment method.

[0071] The technical advantages of this implementation method are as follows: Through the above implementation method, the system automatically establishes voltage and air pressure benchmarks under the current environment after each startup or cartridge replacement, and determines the state based on the relative changes. Compared with the traditional fixed threshold scheme, it has the following advantages: it can adapt to special environments such as different air pressures, high altitudes, cold or high temperatures, preventing misjudgments; it can automatically adapt to different user suction strengths, avoiding misjudgments of false triggering due to weak suction; through dynamic comparison with real-time benchmarks, it effectively eliminates static drift problems caused by system aging, manufacturing differences, etc.; dynamic threshold calculation and judgment can be achieved through software upgrades alone, improving the system's intelligence and saving costs. Therefore, this dynamic threshold adaptive judgment mechanism can significantly enhance the stability, accuracy, and user experience of atomizing devices in diverse usage scenarios.

Figure 7 As shown, the atomizing device includes a microphone, and the working status detection device includes: The working status acquisition module 501 is used to acquire the current working status of the atomizing device when the microphone is detected to be activated. The working status monitoring module 502 is used to monitor the working status of the microphone within a first preset time period when the current working status is an idle state. The working status determination module 503 determines that if the working status of the microphone remains unchanged within the first preset time period, the current working status is an idle state; if the working status of the microphone changes within the first preset time period, the idle state is determined to be erroneously triggered.

If the output voltage sample value is higher than the upper limit of the preset voltage range and continues for a fourth preset time, the current working state is determined to be an unloaded state.

[0077] Furthermore, the working state determination module 503 is specifically used to: determine that the working state of the microphone remains unchanged when it continuously receives the first level signal output by the microphone within a first preset time period; and determine that the working state of the microphone changes when it receives the first level signal output by the microphone changing to the second level signal within the first preset time period.
