Under normal circumstances, the aerosol generating equipment determines whether to execute the heating process based on the user's inhalation action received by the aerosol generating equipment.

[0003] In related technologies, a microphone assembly is installed in an aerosol generating device to detect changes in airflow at the vent of the nozzle assembly in the aerosol generating device, thereby determining whether the aerosol generating device has received a suction action.

[0004] However, because the microphone component is easily permeated by the liquid in the aerosol generating device, its sensitivity may decrease or it may malfunction, resulting in a high probability of accidental touches and a poor user experience. Summary of the Invention

[0014] In some embodiments, the method further includes: When the target level signal changes, the aerosol generating device is controlled to stop heating.

[0015] In some embodiments, the method further includes: If the target level signal is abnormal and the duration of the abnormal signal reaches a preset duration threshold, a first indication message is triggered.

[0030] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment.

[0032] As the demand for aerosol generation equipment increases, so too does the need for improved product safety and user experience. Typically, aerosol generation equipment determines whether to activate the heating function by detecting the presence of an air intake operation. In other words, when an air intake operation is detected, the aerosol generation equipment will activate the heating function. Related technologies usually employ the following single detection method for this determination: The first method involves installing a microphone assembly at the nozzle of the aerosol generator. When a suction operation is received, the microphone assembly outputs a high-level signal; when no suction operation is received, it outputs a low-level signal. The high and low level signals are used to determine whether the aerosol generator has received a suction operation. However, the microphone assembly is susceptible to penetration from the aerosol generating matrix or contamination by condensate, which can reduce its sensitivity or cause it to malfunction, leading to a decrease in the accuracy of its signal output.

[0033] The second method involves installing an airflow detection sensor in the aerosol generator to detect changes in airflow at the vent of the nozzle assembly, thus determining whether the aerosol generator has received an intake action. However, due to the complex operating environment of aerosol generators, airflow changes can occur at the vent of the nozzle assembly in windy conditions or during movement. This can lead to the aerosol generator erroneously activating its heating function, resulting in a higher probability of accidental activation, lower equipment safety, and a poor user experience.

[0034] The third method involves installing a contact sensor in the aerosol generator. When a user comes into contact with the nozzle assembly (usually the lips), a change in capacitance is generated. This change in capacitance determines whether the aerosol generator is in contact with the lips, thus initiating the heating function. However, contact sensors are susceptible to ambient humidity. In high humidity, the sensor may still register contact, leading to a higher probability of false triggering, lower equipment safety, and a poor user experience.

[0035] Based on this, this application provides a heating control method. When a user comes into contact with the nozzle assembly in an aerosol generating device, a first capacitance change output by the contact detection circuit is detected. Furthermore, upon receiving an inhalation operation, a second capacitance change output by the airflow detection circuit is detected. A target capacitance change is determined based on at least one of the first capacitance change, the second capacitance change, or the inhalation operation. The aerosol generating device is then controlled to activate its heating function based on this target capacitance change. In other words, by combining the capacitance changes from the contact detection circuit and the airflow detection circuit, the signal detection method of the aerosol generating device is flexibly selected. Finally, the target capacitance change used as the basis for heating is determined based on the selected signal detection mode, thereby controlling the aerosol generating device to heat, improving the accuracy of inhalation detection, and reducing the probability of false triggering of the aerosol generating device.

[0036] It should be noted that this application may display prompt interfaces, pop-ups, or output voice prompts before and during the collection of user data. These prompt interfaces, pop-ups, or voice prompts are used to inform the user that their data is being collected. This ensures that the application only begins the steps for collecting user data after receiving confirmation from the user regarding the prompt interface or pop-up; otherwise (i.e., without user confirmation), the steps for collecting user data end, meaning no user data is collected. In other words, all user data collected in this application is collected with the user's consent and authorization, and the collection, use, and processing of related user data must comply with the relevant laws, regulations, and standards of the relevant regions.

[0037] The heating control method provided in the embodiments of this application will be described in detail below. For illustrative purposes, please refer to the following. Figure 1 The diagram illustrates a flowchart of a heating control method provided in an exemplary embodiment of this application, which includes steps 110 to 140.

[0038] Step 110: When the user comes into contact with the nozzle assembly, detect the first capacitance change output by the contact detection module.

[0039] The aerosol generating device includes a nozzle assembly, a contact detection module, and an airflow detection module. The contact detection module is used to detect capacitance changes when the user comes into contact with the nozzle assembly.

[0040] To illustrate, after the aerosol generating device is powered on, the battery module provides electrical energy to the heating element in the aerosol generating device, causing it to heat up. After the heating element heats up, it transfers the heat to the aerosol generating matrix, causing the aerosol generating matrix in the aerosol generating device to reach its boiling point and atomize, generating a suspended aerosol for the user to inhale. The process of generating a suspended aerosol is the atomization process.

[0041] To illustrate, the nozzle assembly refers to the component in an aerosol generating device that comes into direct contact with the user (usually their lips). That is, the user can use the nozzle assembly to inhale air into the aerosol generating device, and the user can also use the nozzle assembly to draw in suspended aerosols.

[0042] Indicatively, the contact detection module, also known as the lip-capacitive module, consists of an electrode plate and another electrode inside the nozzle assembly, forming a parallel-plate capacitor. When the user's lips contact the nozzle assembly, the lips, acting as a conductor, enter the electric field between the parallel-plate capacitors, causing a change in capacitance (i.e., a first capacitance change). When the first capacitance change reaches a preset threshold, the contact detection module outputs an electrical signal, triggering the aerosol generating device to perform its heating function.

[0043] Step 120: Upon receiving the user's inhalation operation, detect the change in the second capacitance output by the airflow detection module.

[0044] The airflow detection module is used to detect changes in capacitance when changes in airflow are detected.

[0045] Indicatively, the airflow detection module, also known as the silicon microphone sensor module, is used to detect changes in airflow inside the nozzle assembly. This module contains a Microelectro Mechanical Systems (MEMS) sensor. When the user inhales, air is drawn out of the nozzle assembly, creating a negative pressure (meaning the air pressure inside the nozzle assembly is lower than the external atmospheric pressure). This negative pressure causes the MEMS diaphragm inside the airflow detection module to deform towards the downward-facing electrode, changing the distance between the electrodes and resulting in a change in capacitance (i.e., the second capacitance change). When this second capacitance change reaches a preset threshold, the airflow detection module outputs an electrical signal, triggering the aerosol generation device to perform its heating function.

[0046] To illustrate, when the nozzle assembly receives lip contact, the contact detection module generates a first capacitance change. When the suction operation is received, the airflow detection module generates a second capacitance change. At this time, the first capacitance change is continuously output. That is, in the process of generating the second capacitance change, the contact detection module continuously generates the first capacitance change.

[0047] Step 130: Determine the target capacitance change of the aerosol generating device based on at least one of the first capacitance change, the second capacitance change, or the aspiration operation.

[0048] The target capacitance change includes the first capacitance change and / or the second capacitance change.

[0049] Indicatively, the target capacitance change refers to the criterion used to determine whether to activate the heating function of the aerosol generating equipment.

[0050] Optionally, the change in target capacitance may include the following cases: The first method uses the change in first capacitance as the target change in capacitance. The second method is to use the second capacitance change as the target capacitance change. The third method uses both the change in the first capacitance and the change in the second capacitance as the target capacitance change.

[0051] Optionally, the method for determining the target capacitance change includes at least one of the following methods: The first method is to pre-set judgment criterion 1. If the change in the first capacitance meets the pre-set judgment criterion 1, the change in the first capacitance will be taken as the target capacitance change. The second method is to pre-set judgment standard 1. If the change in the first capacitance does not meet the pre-set judgment standard 1, the change in the second capacitance will be used as the target capacitance change. The third method is to pre-set judgment criterion 2. If the change in the second capacitance meets the pre-set judgment criterion 2, the change in the second capacitance will be used as the target capacitance change. The fourth method is to pre-set judgment standard 2. If the change in the second capacitance does not meet the pre-set judgment standard 2, the change in the first capacitance will be used as the target capacitance change. The fifth method involves pre-setting the inhalation conditions corresponding to the inhalation operation. If the inhalation characteristics corresponding to the inhalation operation meet the corresponding inhalation conditions, the change in the first capacitance and the change in the second capacitance are both taken as the target capacitance change.

[0052] It is worth noting that the above-described method for determining the change in target capacitance is merely an illustrative example, and the embodiments of this application do not limit it.

[0053] The judgment criteria 1, judgment criteria 2 and inhalation conditions described above will be explained in detail in subsequent embodiments.

[0054] As an illustration, the above method of determining the target capacitance change is automatically determined by the aerosol generating equipment based on the actual operating conditions. In addition, the target capacitance change can also be determined by manual selection by the user. That is, the target capacitance change is determined based on the user's operation after receiving the specified user operation.

[0055] Step 140: When the change in target capacitance reaches a preset change threshold, the aerosol generating device is controlled to start the heating function based on the change in target capacitance.

[0056] To illustrate, if the target capacitance change is the first capacitance change, then a first change threshold is preset. When the first capacitance change reaches the first change threshold, the contact detection module outputs a first level signal (e.g., a high level signal) to the main control module. After receiving the first level signal, the main control module controls the aerosol generating device to start the heating function.

[0057] For illustration, if the target capacitance change is the second capacitance change, then a second change threshold is preset. When the second capacitance change reaches the second change threshold, the airflow detection module outputs a second level signal (e.g., a high level signal) to the main control module. After receiving the second level signal, the main control module controls the aerosol generating device to start the heating function.

[0058] To illustrate, if the target capacitance change is a first capacitance change and a second capacitance change, then a first change threshold and a second change threshold are preset. When the first capacitance change reaches the first change threshold, and when the second capacitance change reaches the second change threshold, the contact detection module outputs a first level signal (e.g., a high level signal) to the main control module, and the airflow detection module outputs a second level signal (e.g., a high level signal) to the main control module. After receiving the first level signal and the second level signal, the main control module controls the aerosol generating device to start the heating function.

[0059] The main control module is used to control the operating status of the aerosol generating equipment, such as: powering on, starting heating, stopping heating, starting other functional components (e.g., indicator lights, vibration components, etc.), turning off other functional components, and powering off.

[0060] Optionally, the first change threshold and the second change threshold are the same threshold, or the first change threshold and the second change threshold are different thresholds.

[0061] As an illustration, if the change in target capacitance does not reach the preset change threshold, the aerosol generating device cannot start the heating function.

[0062] The heating control method provided in this application detects a first capacitance change output by a contact detection circuit when a user comes into contact with the nozzle assembly in an aerosol generating device. Furthermore, upon receiving an air intake operation, it detects a second capacitance change output by an airflow detection circuit. Based on at least one of the first capacitance change, the second capacitance change, or the air intake operation, a target capacitance change is determined. The aerosol generating device is then controlled to activate its heating function based on this target capacitance change. In other words, by combining the capacitance changes from the contact detection circuit and the airflow detection circuit, the signal detection method of the aerosol generating device is flexibly selected. Finally, the target capacitance change used as the basis for heating is determined based on the selected signal detection mode, thereby controlling the aerosol generating device to heat. This improves the detection accuracy of the air intake action and reduces the probability of false triggering of the aerosol generating device.

[0063] It should be noted that the "airflow detection module", "contact detection module", "main control module" and other components involved in the embodiments of this application are all physical module structures in the aerosol generation device. Taking the "airflow detection module" as an example, the airflow detection module may include components such as sensors, wires, capacitor plates, solder pads, and housings.

[0064] The following is a detailed explanation of the process for determining the change in target capacitance. Please refer to the illustrative example. Figure 2 It illustrates a flowchart of a heating control method provided in an exemplary embodiment of this application, that is, step 130 further includes steps 131, 132, 133, and 134, as shown below. Figure 2 As shown, the method includes the following steps.

[0065] Step 131: If the duration of the change in the first capacitance value reaching the first amplitude condition reaches a preset duration threshold, then the second capacitance value is determined as the target capacitance value.

[0066] Indicatively, when the nozzle assembly comes into contact with the user's lips, the contact detection module outputs a first electrical signal, and the first electrical signal changes continuously. Therefore, the change in the first capacitance is the change in the signal corresponding to the first electrical signal.

[0067] To illustrate, when the nozzle assembly comes into contact with the user's lips, the capacitance changes. The contact detection circuit has a dedicated integrated chip to convert the capacitance change into an electrical signal, that is, to realize the signal conversion from analog signal to digital signal.

[0068] Optionally, the electrical signal can be implemented as either a voltage signal or a current signal.

[0069] Indicatively, the change in the first capacitance refers to the change in the capacitance between two adjacent changes during the continuous output of the first electrical signal. For example, if the first electrical signal corresponds to 0.3 picofarads (pF) at time 1, 0.8 pF at time 2, and 0.1 pF at time 3, then the first change in the first capacitance is 0.3 to 0.8, which is 0.5 pF. The second change in the first capacitance is 0.8 to 0.1, which is 0.7 pF. Therefore, the change range is 0.5 pF to 0.7 pF, which is 0.2 pF.

[0070] To illustrate, when the nozzle assembly is in normal contact and fits against the user's lips, the electric field change is relatively stable. Therefore, the first electrical signal is continuously output, and the change in the first capacitance corresponding to the first electrical signal remains within a certain range during the continuous output. If the lips are dry, the nozzle assembly and the lips cannot fit tightly together, resulting in an unstable electric field change. Therefore, the change in the first capacitance corresponding to the first electrical signal is larger during the continuous output.

[0071] Therefore, a first amplitude condition (e.g., amplitude threshold) is preset. When the change amplitude of the first capacitance change reaches the first amplitude condition, it indicates that the nozzle assembly and the lips cannot fit properly. At this time, the accuracy of using the first capacitance change as the target capacitance change is low. Therefore, the second capacitance change is selected as the target capacitance change.

[0072] In this embodiment, when the second capacitance change is selected as the target capacitance change, it is called the "silicon microphone priority detection" mode.

[0073] Step 132: If the change in the second capacitance reaches the second amplitude condition, determine the change in the first capacitance as the target capacitance change.

[0074] To illustrate, when the nozzle assembly receives an air intake operation, the airflow detection module outputs a second electrical signal, and the second electrical signal changes continuously. Therefore, the change in the second capacitance is the signal change corresponding to the second electrical signal.

[0075] To illustrate, when the nozzle assembly receives an air intake operation, the capacitance changes. The airflow detection circuit has a dedicated integrated chip to convert the capacitance change into an electrical signal, that is, to realize the signal conversion from analog signal to digital signal.

[0076] Optionally, the electrical signal can be implemented as either a voltage signal or a current signal.

[0077] Indicatively, the variation range of the second capacitance refers to the variation range between two adjacent second capacitance changes during the continuous output of the second electrical signal. For example, if the second electrical signal corresponds to 0.4 picofarads (pF) at time 1, 0.6 pF at time 2, and 0.2 pF at time 3, then the first second capacitance change is 0.4 to 0.8, which is 0.2 pF, and the second second capacitance change is 0.6 to 0.2, which is 0.4 pF. Therefore, the variation range is 0.2 pF to 0.4 pF, which is 0.2 pF.

[0078] Indicatively, when a normal intake operation is received and the environment in which the aerosol generating device is located remains stable (e.g., stable airflow, low or almost no wind speed, low ambient noise level), the change in the electrode plate spacing is relatively stable. Therefore, the signal amplitude of the second electrical signal remains at a low level (e.g., maintained at 1.5 volts (V)).

[0079] Therefore, if an intake operation is received, but there is interference in the environment where the aerosol generating device is located (e.g., stable airflow, high wind speed, high ambient noise level), the electrode plate spacing will be unstable. As a result, the signal amplitude of the second electrical signal may remain at a high level (e.g., at 2V).

[0080] Therefore, a second amplitude condition (e.g., a signal threshold) is preset. If the second electrical signal continuously reaches the signal threshold within a preset time period, it is determined that the second capacitance change has reached the second amplitude condition. At this time, if the second capacitance change is selected as the target capacitance change, the accuracy of the target capacitance change will be low. Therefore, the first capacitance change is selected as the target capacitance change.

[0081] In this embodiment, when the first capacitance change is selected as the target capacitance change, it is called the "capacitance priority detection" mode.

[0082] Step 133: Obtain multiple historical intake operations received by the aerosol generating device within a historical time range.

[0083] Indicatively, an inhalation operation includes the real-time inhalation operation received at the current moment, as well as historical inhalation operations received within a historical time range prior to the current moment.

[0084] To illustrate, a historical time range is pre-defined (e.g., the time range within 5 minutes before the current time is used as the historical time range), and inhalation operations received within the historical time range are collected as historical inhalation operations.

[0085] Step 134: If the time interval between multiple historical inhalation operations is less than a preset interval threshold, determine the first capacitance change and the second capacitance change as the target capacitance change.

[0086] This is an illustrative example of how, after identifying multiple historical inhalation operations, the selection method for determining the target capacitance change is based on the inhalation characteristics of these operations.

[0087] In this embodiment, if the time interval between multiple historical inhalation operations is less than a preset interval threshold, it indicates that the user's inhalation habit is rapid and continuous inhalation. Therefore, both the first capacitance change and the second capacitance change are used as the target capacitance change to achieve dual verification of inhalation detection, which can reduce the probability of false touch and improve the control accuracy and efficiency of the heating function.

[0088] In this embodiment, when the first capacitance change and the second capacitance change are selected as the target capacitance change, it is called the "cooperative detection" mode.

[0089] In some embodiments, in response to receiving a mode selection operation, a target capacitance change corresponding to the mode selection operation is determined; wherein the mode selection operation includes at least one of the following operation methods: when a target button is provided in the aerosol generating device, a first trigger operation on the target button; when a DIP switch is provided in the aerosol generating device, a toggle operation on the DIP switch; when a touch area is provided in the aerosol generating device, a second trigger operation on the touch area.

[0090] In illustrative terms, in addition to the above-mentioned method of automatically determining the detection mode, the target capacitance change corresponding to the mode selection operation can also be determined through the mode selection operation.

[0091] In the first implementation, a target button is provided in the aerosol generating device. A first trigger operation is performed on the target button. For example, triggering it once in a row determines the "capacitor priority detection" mode, triggering it twice in a row determines the "silicon microphone priority detection" mode, and triggering it three times in a row determines the "cooperative detection" mode.

[0092] In the second implementation, a DIP switch is provided in the aerosol generating device. The DIP switch is toggled, for example: toggling it once to determine the "capacitor priority detection" mode, toggling it twice to determine the "silicon microphone priority detection" mode, and toggling it three times to determine the "cooperative detection" mode.

[0093] In the third implementation, a touch area is provided in the aerosol generating device, and a second trigger operation is performed on the touch area. For example, three controls are displayed in the touch area, which correspond to the three different modes mentioned above. The trigger operation of the specified control is used as the second trigger operation, and the corresponding detection mode is determined according to the specified control.

[0094] Step 140: When the change in target capacitance reaches a preset change threshold, the aerosol generating device is controlled to start the heating function based on the change in target capacitance.

[0095] In some embodiments, when the change in target capacitance reaches a preset change threshold, a target level signal is generated; and the heating function of the aerosol generating device is activated based on the target level signal.

[0096] To illustrate, if the target capacitance change is the first capacitance change, then a first change threshold is preset. When the first capacitance change reaches the first change threshold, the contact detection module outputs a first level signal (e.g., a high level signal) to the main control module. After receiving the first level signal, the main control module controls the aerosol generating device to start the heating function.

[0097] For illustration, if the target capacitance change is the second capacitance change, then a second change threshold is preset. When the second capacitance change reaches the second change threshold, the airflow detection module outputs a second level signal (e.g., a high level signal) to the main control module. After receiving the second level signal, the main control module controls the aerosol generating device to start the heating function.

[0098] To illustrate, if the target capacitance change is a first capacitance change and a second capacitance change, then a first change threshold and a second change threshold are preset. When the first capacitance change reaches the first change threshold, and when the second capacitance change reaches the second change threshold, the contact detection module outputs a first level signal (e.g., a high level signal) to the main control module, and the airflow detection module outputs a second level signal (e.g., a high level signal) to the main control module. After receiving the first level signal and the second level signal, the main control module controls the aerosol generating device to start the heating function.

[0099] The main control module is used to control the operating status of the aerosol generating equipment, such as: powering on, starting heating, stopping heating, starting other functional components (e.g., indicator lights, vibration components, etc.), turning off other functional components, and powering off.

[0100] Optionally, the first change threshold and the second change threshold are the same threshold, or the first change threshold and the second change threshold are different thresholds.

[0101] In some embodiments, when there is a level change in the target level signal, the aerosol generating device is controlled to stop heating.

[0102] To illustrate, if the target level signal changes, for example, from a high level signal to a low level signal, it means that the change in the target capacitance does not meet the pre-defined threshold for the change. In this case, the aerosol generating equipment is controlled to stop heating.

[0103] In some embodiments, if there is a signal anomaly in the target level signal and the duration of the signal anomaly reaches a preset duration threshold, a first indication message is triggered. The first indication message is used to indicate that there is a fault in the aerosol generating device.

[0104] Indicatively, the abnormal behavior of the target level signal can be realized as the level signal continuously changing within a certain time range, for example, changing from a high level signal to a low level signal and then back to a high level signal. At this time, the first indication information is triggered (for example, the first indicator light is lit). The first indication information indicates that there is a fault in the aerosol generating equipment, and the aerosol generating equipment cannot perform the heating function at this time.

[0105] In this embodiment, in standby mode, the airflow sensor works intermittently (e.g., wakes up 10ms per second), the contact sensor maintains low-power detection, and after triggering, the sampling rate is dynamically adjusted according to the usage frequency, and enters sleep mode during inactive periods.

[0106] The heating control method provided in this application detects a first capacitance change output by a contact detection circuit when a user comes into contact with the nozzle assembly in an aerosol generating device. Furthermore, upon receiving an air intake operation, it detects a second capacitance change output by an airflow detection circuit. Based on at least one of the first capacitance change, the second capacitance change, or the air intake operation, a target capacitance change is determined. The aerosol generating device is then controlled to activate its heating function based on this target capacitance change. In other words, by combining the capacitance changes from the contact detection circuit and the airflow detection circuit, the signal detection method of the aerosol generating device is flexibly selected. Finally, the target capacitance change used as the basis for heating is determined based on the selected signal detection mode, thereby controlling the aerosol generating device to heat. This improves the detection accuracy of the air intake action and reduces the probability of false triggering of the aerosol generating device.

The airflow detection module detects a second capacitance change output by itself when a user inhales; the airflow detection module is configured to cause a capacitance change when a change in airflow is detected. The signal processing module determines a target capacitance change corresponding to the aerosol generating device based on at least one of the first capacitance change, the second capacitance change, and the inhalation operation; the target capacitance change includes the first capacitance change and / or the second capacitance change. The heating execution module controls the aerosol generating device to activate its heating function based on the target capacitance change when the target capacitance change reaches a preset threshold value.

[0117] In some embodiments, when the aerosol generating device is powered on and the user comes into contact with the nozzle assembly, the change in first capacitance output by the multiple electrode plates is detected.

[0118] In some embodiments, when the change in the first capacitance corresponding to the electrode plate reaches a first change threshold, it is determined that there is a contact operation in the nozzle assembly; when the number of electrode plates corresponding to the first change threshold reaches a preset number threshold, the first pin is controlled to output a target level signal.
