Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomization control method and an electronic atomization device. Background Technology

[0002] An electronic atomizing device is a device that generates aerosols for user use. It contains a heating element and an atomizing medium. When the heating element is energized, it heats the atomizing medium, raising its temperature. Once the atomizing medium reaches its atomization temperature, it begins to atomize, producing an aerosol for the user.

[0003] To meet user needs, electronic atomizing devices with two or more heating elements have emerged. In actual use, regardless of the desired amount or location of the aerosol, these devices with multiple heating elements heat up simultaneously to generate aerosol. If any heating element malfunctions, the electronic atomizing device may not adequately meet the user's vaping requirements. Therefore, the reliability of traditional electronic atomizing devices needs improvement. Summary of the Invention

[0004] Therefore, it is necessary to address the technical problem of the need to improve the operational reliability of traditional electronic atomizing devices by providing an atomization control method and an electronic atomizing device that can improve the operational reliability of electronic atomizing devices.

[0005] Firstly, this application provides a method for controlling atomization.

[0006] The method is applied to an electronic atomizing device, the electronic atomizing device including an airflow sensor and at least two heating elements, each of the heating elements being located in a different airflow channel, the heating elements being used to atomize the atomizing medium stored in the electronic atomizing device; the method includes:

[0007] In response to the atomization start signal, the heating elements are controlled to heat up; the atomization start signal is detected by an airflow sensor.

[0009] Determine whether there is an abnormal heating element based on the heating parameters of each heating element;

[0010] If present, adjust the operating state of the abnormal heating element.

[0011] In one embodiment, each of the airflow channels has an independent airflow outlet.

[0012] In one embodiment, determining whether there is an abnormal heating element based on the heating parameters of each heating element includes:

[0013] Based on the relationship between the heating parameters of each heating element and the preset heating parameter threshold, it is determined whether there is an abnormal heating element.

[0014] In one embodiment, the heating parameter includes a resistance value, the preset heating parameter threshold includes a preset resistance value threshold, and the step of determining whether there is an abnormal heating element based on the relationship between the heating parameters of each heating element and the preset heating parameter threshold includes:

[0015] Based on the temperature coefficient of resistance of each heating element, and according to the relationship between the resistance value of each heating element and a preset resistance threshold, it is determined whether there is an abnormal heating element.

[0016] In one embodiment, the preset resistance threshold includes a first resistance threshold and a second resistance threshold, the first resistance threshold being less than the second resistance threshold, and the abnormal heating element includes a heating element with a first abnormal heating state and a heating element with a second abnormal heating state.

[0017] When the temperature coefficient of resistance of the heating element is positive, the step of determining whether there is an abnormal heating element based on the relationship between the resistance value of each heating element and a preset resistance threshold includes:

[0018] If the resistance of the heating element is less than the first resistance threshold, the heating element is considered to be normal.

[0019] If the resistance of the heating element is greater than or equal to the first resistance threshold and less than the second resistance threshold, the heating element is determined to be a heating element with a first abnormal heating state.

[0020] If the resistance of the heating element is greater than or equal to the second resistance threshold, the heating element is determined to be a heating element with a second abnormal heating state; the temperature of the heating element with the second abnormal heating state is greater than the temperature of the heating element with the first abnormal heating state.

[0021] In one embodiment, adjusting the operating state of the abnormal heating element includes:

[0025] In one embodiment, obtaining the heating parameters of each of the heating elements includes:

[0026] During the heating interval time of each heating element, the heating parameters of each heating element are obtained.

[0027] Secondly, this application also provides an electronic atomizing device, including an airflow sensor, at least two heating elements, a processor, and a memory. Each of the heating elements is located in a different airflow channel and is heated under the control of the processor. The heating elements are used to atomize the atomizing medium stored in the electronic atomizing device. The memory stores a computer program, which, when executed by the processor, causes the processor to perform the method of any of the above embodiments.

[0028] The aforementioned atomization control method and electronic atomization device include at least two heating elements, each located in a different airflow channel. These heating elements atomize the atomization medium stored within the electronic atomization device. The atomization control method includes: controlling the heating of each heating element in response to an atomization start signal detected by an airflow sensor; acquiring heating parameters characterizing the heating state of each heating element; determining whether an abnormal heating element exists based on its heating parameters; and adjusting the operating state of the abnormal heating element if one exists. By detecting the heating parameters of each heating element under its actual heating state, it is possible to determine whether the heating element is malfunctioning.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] The atomization control method provided in this application embodiment can be applied to, for example... Figure 1 The illustrated electronic atomizing device includes an airflow sensor 102 and at least two heating elements 104, each located in a different airflow channel. It is understood that the airflow channels may share a single airflow inlet, with the airflow sensor 102 positioned at that inlet. Alternatively, the airflow sensor 102 may be positioned within an airflow channel or between two airflow channels, allowing it to sense the airflow in both channels. The electronic atomizing device stores an atomizing medium; exemplarily, the atomizing medium is disposed in each of the different airflow channels, and within each airflow channel, the heating element 104 heats the atomizing medium to generate an aerosol.

[0042] Taking a scenario where all airflow channels share a single airflow inlet, and an airflow sensor 102 is installed inside the airflow inlet, the airflow sensor 102 is used to detect whether there is an atomization start signal at the airflow inlet. Once an atomization start signal is detected, it indicates that the user has a need to use aerosol. At this time, the heating element 104 starts working, heating the atomization medium in the airflow channel to generate aerosol.

[0043] Furthermore, the electronic atomizing device may also include a processor 106. The processor 106 is connected to the airflow sensor 102 and the heating element 104, and can receive the detection results from the airflow sensor 102 and store them in the memory 107. It can also control the operating state of the heating element 104. For example, after receiving an atomization start signal from the airflow sensor 102, the processor 106 can control one or more heating elements 104 to start working, heating the atomizing medium in the airflow channel to generate an aerosol. It is understood that in other embodiments, the processor 106 may also be indirectly connected to the heating element 104 or the airflow sensor 102 through other devices or structures, and may also be connected to other types of devices, which are not limited here.

[0044] The atomization control method can be executed by the processor 106 in the electronic atomization device, or by a terminal or server that is communicatively connected to the electronic atomization device. The terminal can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. The server can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server providing cloud computing services.

[0045] In one exemplary embodiment, such as Figure 2 As shown, an atomization control method is provided, exemplified by the method being executed by a processor in an electronic atomization device, including steps 202 to 208. Wherein:

[0046] Step 202: In response to the atomization start signal, control the heating of each heating element.

[0047] The atomization start signal is detected by the airflow sensor and then sent to the processor. The airflow sensor is connected to the processor. The airflow sensor is used to detect changes in airflow. For example, when a user inhales into the electronic atomizing device, the airflow at the airflow inlet changes. After the airflow sensor detects the change in airflow, it generates the atomization start signal.

[0048] The type of airflow sensor is not unique; for example, it can be a microphone. A microphone is a parallel-plate capacitor consisting of a diaphragm and a back electrode. When the airflow changes, the airflow differential pressure causes the diaphragm to deform, resulting in a change in capacitance. The signal from this capacitance change can be used as a nebulization start signal. Microphones offer high sensitivity and accurate detection of airflow changes.

[0049] The atomization activation signal indicates that the user has a need for aerosol application. After receiving the atomization activation signal, the processor controls the heating elements to heat up simultaneously, raising the atomization medium in their respective airflow channels.

[0050] Step 204: Obtain the heating parameters of each heating element.

[0051] After the heating element starts working and generating heat, the processor acquires the heating parameters of each heating element during the heating process. These heating parameters characterize the heating state of the heating element. The type of heating parameter is not limited, as long as it can characterize the heating state of the heating element. For example, the heating parameter can be the temperature of the heating element; the temperature level characterizes the heating state of the heating element. It is understood that in other embodiments, the heating parameter can also be of other types, as long as those skilled in the art believe it is feasible.

[0052] Depending on the type of heating parameter, the processor can obtain the heating parameters of each heating element through different heating parameter detection modules. Taking temperature as an example, the heating parameter detection module can be a temperature sensor, which can detect the temperature of the heating element and transmit it to the processor. Alternatively, the heating parameter can also be resistance, in which case the processor can determine the temperature of the heating element by obtaining its own resistance, without the need for an additional temperature sensor.

[0053] Furthermore, when the processor acquires the heating parameters of the heat source, it can do so in real time to obtain more comprehensive heating parameter data. Alternatively, the processor can acquire the heating parameters at preset time intervals to reduce the processor's workload.

[0054] Step 206: Determine whether there are any abnormal heating elements based on the heating parameters of each heating element.

[0055] After obtaining the heating parameters of the heating element, it is possible to determine whether there is an abnormal heating element. An abnormal heating element refers to a heating element with an abnormal heating state. An abnormal heating state can be due to a mismatch between the heating state and the user's needs, or a mismatch between the heating state and the operating requirements of the electronic atomization device.

[0056] There is no single way to determine whether a heating element is abnormal based on its heating parameters. For example, one can determine whether a heating element is abnormal based on the magnitude of the heating parameters or on the changes in the heating parameters.

[0057] Step 208: If present, adjust the working state of the abnormal heating element.

[0058] If an abnormal heating element is identified based on heating parameters, the operating status of the abnormal heating element is adjusted. The operating status can include whether it is operating and its specific operating state, such as heating status.

[0059] There is no single way to adjust the working state of an abnormal heating element. For example, the heating element can be controlled by switching the power on and off, or its heating time can be controlled by adjusting the working time of the heating element, thereby adjusting the heating state of the heating element.

[0060] For example, if an abnormal heating element is identified based on heating parameters, and the abnormal heating element is in a state of excessively high temperature, the heating element can be controlled to stop working in order to avoid further adverse effects caused by its continued operation.

[0061] In this embodiment, the electronic atomizing device includes at least two heating elements, each located in a different airflow channel. The heating elements are used to atomize the atomizing medium stored in the electronic atomizing device. The atomization control method includes: controlling the heating of each heating element in response to an atomization start signal detected by an airflow sensor; acquiring heating parameters characterizing the heating state of each heating element; determining whether an abnormal heating element exists based on the heating parameters; and adjusting the operating state of the abnormal heating element if one exists. By detecting the heating parameters of each heating element under its actual heating state, it is possible to determine whether the heating element is malfunctioning. Upon determining the presence of an abnormal heating element, the operating state of the abnormal heating element can be adjusted promptly. This allows for adjustments to the operating state of the heating elements based on actual conditions, ensuring that the aerosol actually generated by the heating elements better meets user needs and improving the reliability of the electronic atomizing device.

[0062] This atomization control method can be applied to different types of electronic atomization devices. For example, in one embodiment, each airflow channel has an independent airflow outlet but shares a common airflow inlet. Thus, the heating element in each airflow channel can operate in different states based on the detection result of an airflow sensor at the airflow inlet, and the aerosol generated by each heating element after heating is output from different airflow outlets for user use.

[0063] It is understandable that aerosols produced by different airflow outlets can be used in one place, such as the user's mouth. Alternatively, aerosols produced by different airflow outlets can be used in multiple places, such as aerosols produced by the airflow outlets of two airflow channels being used in the user's two nostrils respectively.

[0064] When each airflow channel has an independent airflow outlet, different airflow channels may have different aerosol usage requirements. When different airflow channels have different aerosol usage requirements, such as only needing a single airflow channel to generate aerosols, if all heating elements operate in the same way, the aerosols generated in airflow channels that do not require aerosols may not be carried away in time. The aerosols will accumulate in the airflow channels, forming condensate, resulting in aerosol waste and affecting the quality of the aerosols provided by that airflow channel in the next cycle.

[0065] The atomization control method provided in this application responds to the atomization start signal detected by the airflow sensor, controls the heating of each heating element, and then acquires heating parameters characterizing the heating state of each heating element. After identifying any abnormal heating element based on these parameters, the operating state of the abnormal heating element is adjusted. By detecting the heating parameters of each heating element under its actual heating state, it is possible to determine whether the heating element is malfunctioning. Timely adjustment of the abnormal heating element's operating state, based on actual conditions, effectively avoids aerosol waste and quality issues caused by unnecessary aerosol use. This ensures that the aerosol actually generated by the heating element better meets user needs and improves the reliability of the electronic atomization device.

[0066] For example, in a scenario where the aerosols generated at the airflow outlets of two airflow channels are used by the user's two nostrils respectively, if the user only inhales through one nostril, the aerosol generated in the airflow channel corresponding to that nostril can be used by the user. However, the aerosol generated in the other airflow channel cannot be carried away in time, causing the temperature of the heating element in that channel to continuously rise, resulting in an abnormal state. The atomization control method provided in this application embodiment can stop the abnormal heating element from operating after detecting an abnormality, thereby protecting the abnormal heating element and improving the performance of the electronic atomization device.

[0067] In one exemplary embodiment, such as Figure 3 As shown, step 206 includes step 306.

[0068] Step 306: Determine whether there are any abnormal heating elements based on the relationship between the heating parameters of each heating element and the preset heating parameter threshold.

[0069] The type of the preset heating parameter threshold is the same as the type of heating parameter. The preset heating parameter threshold is related to the type of atomizing medium, the type of heating element, and the structure of the electronic atomizing device. The specific value of the preset heating parameter threshold can be determined after experimentation. Once determined, it is stored in memory and can be directly retrieved when needed.

[0070] After obtaining the heating parameters of each heating element, the heating parameters of each heating element are compared with the preset heating parameter threshold. Based on the comparison results, it is determined whether the heating element corresponding to each heating parameter is abnormal, thereby determining whether there is an abnormal heating element in the electronic atomization device.

[0071] The method for determining whether an abnormal heating element exists based on the relationship between the heating parameters of each heating element and a preset heating parameter threshold is not limited. For example, if a heating parameter is greater than the preset heating parameter threshold, the heating parameter is determined to be abnormal, and thus the heating element corresponding to that heating parameter is determined to be abnormal. It is understood that in other embodiments, other methods can also be used to determine whether the heating parameter is abnormal, and this is not limited here.

[0072] In this embodiment, the presence of an abnormal heating element is determined based on the relationship between the heating parameters of each heating element and a preset heating parameter threshold. This allows for rapid identification of abnormal heating element states and improves detection efficiency.

[0073] In one exemplary embodiment, the heating parameter includes a resistance value, and the preset heating parameter threshold includes a preset resistance value threshold, such as... Figure 4 As shown, step 306 includes step 406.

[0074] Step 406: Based on the temperature coefficient of resistance of each heating element, determine whether there is an abnormal heating element according to the relationship between the resistance value of each heating element and the preset resistance threshold.

[0075] The temperature coefficient of resistance (TCR) represents the relative change in resistance when the temperature changes by 1°C, expressed in ppm / °C. A positive TCR means that the resistance of the heating element increases with its temperature. A negative TCR means that the resistance of the heating element decreases with its temperature. The preset resistance threshold is related to the type of atomizing medium, the type of heating element, and the structure of the electronic atomizing device. The specific value of the preset resistance threshold can be determined after experimentation. Once determined, it is stored in memory and can be directly retrieved when needed.

[0076] To determine whether there is an abnormal heating element, based on the temperature coefficient of resistance of each heating element and the relationship between the resistance value of each heating element and the preset resistance threshold, the temperature coefficient of resistance of the heating element can be determined first. Then, based on the temperature coefficient of resistance, the relationship between the resistance value of each heating element and the preset resistance threshold can be used to determine whether there is an abnormal heating element.

[0077] For example, when the temperature coefficient of resistance of the heating element is positive, the resistance value of each heating element is compared with a preset resistance threshold. If a resistance value greater than the preset threshold is detected, it indicates that the resistance of the heating element is too high and the temperature is also too high. The heating element corresponding to this resistance value is then identified as an abnormal heating element. When the temperature coefficient of resistance of the heating element is negative, the resistance value of each heating element is compared with the preset resistance threshold. If a resistance value less than the preset threshold is detected, it indicates that the resistance of the heating element is too low and the temperature is also too high. The heating element corresponding to this resistance value is then identified as an abnormal heating element.

[0078] In this embodiment, the heating state of the heating element is determined based on its resistance value. Then, the temperature coefficient of resistance of the heating element and a preset resistance threshold are combined to determine whether the heating element is abnormal. This allows for the determination of whether the heating element is abnormal based on its resistance characteristics. The resistance value can be detected by the circuit, which helps to simplify the structure of the electronic atomization device.

[0079] Further, in an exemplary embodiment, the preset resistance threshold includes a first resistance threshold and a second resistance threshold, the first resistance threshold being less than the second resistance threshold, and the abnormal heating element includes a heating element with a first abnormal heating state and a heating element with a second abnormal heating state; the temperature of the heating element with the second abnormal heating state is greater than the temperature of the heating element with the first abnormal heating state. When the temperature coefficient of resistance of the heating element is positive, such as... Figure 5 As shown, in step 406, the step of determining whether there is an abnormal heating element based on the relationship between the resistance value of each heating element and the preset resistance threshold includes steps 502 to 506.

[0080] Step 502: If the resistance of the heating element is less than the first resistance threshold, the heating element is judged to be normal.

[0081] Step 504: If the resistance of the heating element is greater than or equal to the first resistance threshold and less than the second resistance threshold, the heating element is determined to be a heating element with an abnormal first heating state.

[0082] Step 506: If the resistance of the heating element is greater than or equal to the second resistance threshold, the heating element is determined to be a heating element with an abnormal second heating state.

[0083] If the resistance of the heating element is less than the first resistance threshold, it indicates that the resistance of the heating element is relatively low. Because the temperature coefficient of resistance of the heating element is positive, the temperature of the heating element is low at this time, and the heating element is working normally.

[0084] If the resistance of the heating element is greater than or equal to the first resistance threshold and less than the second resistance threshold, it indicates that the resistance of the heating element is too high. Since the temperature coefficient of resistance of the heating element is positive, the temperature of the heating element is too high at this time, thus the heating element is judged to be in the first abnormal heating state.

[0085] If the resistance of the heating element is greater than or equal to the second resistance threshold, it indicates that the resistance of the heating element is high. Because the temperature coefficient of resistance of the heating element is positive, the temperature of the heating element is high at this time, thus the heating element is judged to be in the second abnormal heating state.

[0086] In this embodiment, the preset resistance threshold includes a first resistance threshold and a second resistance threshold. The first resistance threshold is less than the second resistance threshold. Abnormal heating elements include heating elements with abnormal first heating states and heating elements with abnormal second heating states. The temperature of the heating element with abnormal second heating states is greater than the temperature of the heating element with abnormal first heating states. When the temperature coefficient of resistance of the heating element is positive, if the resistance of the heating element is less than the first resistance threshold, the heating element is judged to be normal; if the resistance of the heating element is greater than or equal to the first resistance threshold and less than the second resistance threshold, the heating element is judged to be a heating element with abnormal first heating states; if the resistance of the heating element is greater than or equal to the second resistance threshold, the heating element is judged to be a heating element with abnormal second heating states. By dividing the preset resistance threshold into multiple intervals, the normal or abnormal state of the heating element can be further refined according to the relationship between the resistance of the heating element and the size of each interval, thereby improving the refinement of the heating element state detection.

[0087] In one exemplary embodiment, such as Figure 6 As shown, step 208 includes step 608: reducing the heating power of the abnormal heating element.

[0088] Once an abnormal heating element is identified, reducing its heating power can prevent its temperature from rising further and causing further damage.

[0089] There are multiple ways to reduce the heating power of an abnormal heating element. For example, the heating power can be reduced by decreasing the on-time of the abnormal heating element. Alternatively, the heating power can be reduced by decreasing the supply voltage of the abnormal heating element.

[0090] In a more scalable manner, if a heating element is determined to be in a first abnormal heating state, its heating power can be reduced by a first power. If a heating element is determined to be in a second abnormal heating state, its heating power can be reduced by a second power or it can be shut down. The second power is greater than the first power. Therefore, by reducing the heating power of the abnormal heating element by different amounts based on its actual heating state, more precise control of the heating element can be achieved.

[0091] In this embodiment, after determining that there is an abnormal heating element, the heating power of the abnormal heating element is reduced, which can prevent the temperature of the abnormal heating element from rising further and causing further damage.

[0092] In one exemplary embodiment, such as Figure 7 As shown, after step 608, the atomization control method further includes step 708: increasing the heating power of the normal heating element.

[0093] Among them, the normal heating element refers to the heating element in the electronic atomization device other than the abnormal heating element.

[0094] After reducing the heating power of the abnormal heating element, the heating power of the normal heating element is increased so that the total amount of aerosol generated by each heating element is closer to the user's needs.

[0095] In a scalable manner, when increasing the heating power of the normal heating element, the heating power of the normal heating element can be increased to be less than or equal to a preset heating power threshold. This prevents the normal heating element from burning due to excessive power, while also ensuring a certain level of atomization.

[0096] In this embodiment, by reducing the heating power of the abnormal heating element and increasing the heating power of the normal heating element, the total amount of aerosol generated by each heating element can be more closely aligned with the user's needs.

[0097] In an exemplary embodiment, prior to step 202, the atomization control method further includes the step of obtaining the initial resistance value of each heating element. Step 206 includes the step of determining whether there is an abnormal heating element based on the initial resistance value of each heating element and the heating parameters of each heating element.

[0098] Due to variations in ambient temperature, atomizing medium, and the location of the heating element, the initial resistance of different heating elements may differ. Therefore, in this embodiment, before controlling the heating element to heat up, the initial resistance of each heating element is first obtained and taken into account in subsequent processing steps to reduce the adverse effects of initial resistance deviation.

[0099] In the step of determining whether there is an abnormal heating element based on the heating parameters of each heating element, the influence of the initial resistance of the heating element is further considered. Based on the initial resistance and heating parameters of each heating element, it is determined whether there is an abnormal heating element. For example, a preset heating parameter threshold can be determined based on the initial resistance of each heating element, and then the relationship between the heating parameters of each heating element and the preset heating parameter threshold can be used to determine whether there is an abnormal heating element.

[0100] In this embodiment, in response to the atomization start signal and before controlling the heating of each heating element, the atomization control method further includes the steps of: obtaining the initial resistance value of each heating element; and determining whether there is an abnormal heating element based on the heating parameters of each heating element. This includes the step of determining whether there is an abnormal heating element based on the initial resistance value and heating parameters of each heating element. Therefore, when determining whether a heating element is abnormal, considering the influence of its initial resistance value and judging whether the heating element is abnormal based on its actual initial resistance value helps improve the accuracy of the judgment.

[0101] In an exemplary embodiment, step 204 includes the step of: acquiring the heating parameters of each heating element during the heating interval time period of each heating element.

[0102] The heating interval time period refers to the time period during which the heating element does not heat up. The processor can control the heating of the heating element and acquire its heating parameters through different branches. During the heating interval time period of each heating element, the heating element does not heat up, and the processor can acquire the heating parameters of each heating element by disconnecting the branch controlling the heating of the heating element and turning on the branch acquiring the heating parameters of the heating element.

[0103] In this embodiment, the heating parameters of each heating element are acquired during the heating interval time of each heating element. This allows for separate control of the heating elements and acquisition of their heating parameters at different time intervals, improving the performance of the electronic atomization device.

[0104] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages.

The processors involved in the embodiments provided in this application may be general-purpose processors, central processing units, graphics processing units, digital signal processors, programmable logic devices, quantum computing-based data processing logic devices, artificial intelligence (AI) processors, etc., and are not limited to these.

[0107] For example, different airflow channels are each equipped with an atomizing medium. Within each airflow channel, a heating element heats the atomizing medium to generate an aerosol. All airflow channels share a single airflow inlet, and an airflow sensor is located within this inlet. The airflow sensor detects whether an atomization activation signal is present at the airflow inlet. Upon detecting an atomization activation signal, it indicates that the user has a need for aerosol. At this point, the heating element begins operation, heating the atomizing medium within the airflow channel to generate an aerosol.

[0108] In addition, the electronic atomizing device may also include a heating parameter detection module and a heating control circuit. The heating parameter detection module connects the heating element and the processor, and can detect the heating parameters of the heating element and transmit them to the processor. The type of heating parameter detection module is not limited; for example, it could be a resistance detection module that detects the resistance of the heating element and transmits it to the processor.

[0109] Furthermore, the processor is connected to an airflow sensor and also to a heating element via a heating control circuit. One heating control circuit can be connected to one heating element, and each heating control circuit is connected to the processor. The processor can receive the detection results from the airflow sensor and control the heating control circuits, thereby controlling the operating state of the heating element. The heating control circuit may include a heating control switch, with its first terminal connected to a power supply, its second terminal connected to the heating element, and its control terminal connected to the processor. The processor can send different level signals to the control terminal of the heating control switch to control its on / off state. When the heating control switch is on, its first and second terminals are connected, and the heating element is powered on. Therefore, the processor can control the operating state of the heating element by controlling the on / off state of the heating control switch. For example, after receiving an atomization start signal from the airflow sensor, the processor can control the heating control circuit to turn on, causing the heating element to start working and heating the atomizing medium in the airflow channel to generate an aerosol.

[0110] The aforementioned electronic atomizing device, in response to the atomization start signal detected by the airflow sensor, controls the heating of each heating element; acquires heating parameters characterizing the heating state of each heating element; determines whether there is an abnormal heating element based on the heating parameters of each heating element; if so, adjusts the working state of the abnormal heating element. By detecting the heating parameters of each heating element under actual heating conditions, it is possible to determine whether the heating element is malfunctioning. Upon identifying an abnormal heating element, its working state can be adjusted promptly to adjust the working state of the heating element according to the actual situation, so that the aerosol actually generated by the heating element can better meet user needs and improve the reliability of the electronic atomizing device.

[0111] In one embodiment, the aerosol generated by the electronic atomizing device is inhaled by the user through the nose. When the aerosol generated at the airflow outlets of the two airflow channels is used by the user's two nostrils respectively, if the user only inhales through one nostril, the aerosol generated in the airflow channel corresponding to that nostril can be used by the user. However, the aerosol generated in the other airflow channel cannot be carried away in time, causing the temperature of the heating element in that channel to continuously rise, resulting in an abnormal state. The atomization control method provided in this application embodiment can stop the abnormal heating element from operating after detecting an abnormality, thereby protecting the abnormal heating element and improving the performance of the electronic atomizing device.

[0112] To better understand the above embodiments, a detailed explanation is provided below with reference to a specific embodiment. In one embodiment, the electronic atomizing device includes an airflow sensor and two heating elements, such as... Figure 8 As shown, each heating element 104 is located in two different airflow channels, sharing a common airflow inlet and having an independent airflow outlet. An airflow sensor is located at the airflow inlet. Since the airflow sensor is a microphone, and both heating elements 104 are controlled by the same microphone, it's possible that when a single airway is drawn in, both heating elements 104 will heat up simultaneously upon microphone triggering. If the atomized aerosol cannot be carried away in time, it will accumulate in the airway, forming condensate, affecting the next draw and wasting atomized liquid. Therefore, without adding a new microphone to control both airways, the resistance of the heating element 104 is monitored in real-time to determine the airflow status and adjust the output power of the two heating elements 104 accordingly. This ensures sufficient atomization even with single-airway drawing and avoids the problem of atomization without drawing.

[0113] Please refer to the structure of the electronic atomizing device. Figure 9 It includes heating element 1, heating element 2, heating parameter detection module, processor, airflow sensor, and power supply. The heating parameter detection module is a resistance detection module, the processor is an MCU, and the airflow sensor is a microphone.

[0114] An electronic atomizing device like the one described above may include multiple heating elements, but the main control process for each heating element is basically the same. For the atomization control steps of a single heating element, please refer to [link to relevant documentation]. Figure 10 ,include:

[0115] Step 1: The processor obtains the initial resistance value of the heating element before atomization. This step can eliminate the adverse effects of initial resistance deviation.

[0116] Step 2: Set the first and second resistance thresholds according to the product characteristics. The first resistance threshold is R0 + R1, where R0 is the initial resistance and R1 is the first resistance setting. This first resistance threshold is the normal atomization threshold. The second resistance threshold is R0 + R2, where R0 is the initial resistance and R2 is the second resistance setting, and R1 is less than R2. This second resistance threshold is the atomization threshold for insufficient airflow.

[0117] Step 3: When atomization starts, the resistance value Rt of each heating element is periodically detected at one or more PWM low-level moments.

[0118] Step 4: If the resistance Rt of the heating element is lower than the first resistance threshold (Rt < R0 + R1), the processor maintains the original power output setting of the heating element; if the resistance Rt of the heating element is higher than the first resistance threshold and lower than the second resistance threshold (R0 + R1 < Rt < R0 + R2), the corresponding power output of the heating element is adjusted; if the resistance Rt of the heating element is higher than the second resistance threshold (Rt > R0 + R2), the power output of the heating element is turned off.

[0119] In step 2, the product characteristics are determined by the atomizing medium, the heating element model, and the structure of the electronic atomizing device. The R1 and R2 settings of the heating element of each electronic atomizing device are different and are stored as fixed values ​​in the MCU.

[0120] The "adjustment" method in step 4 is specifically adjusted based on the overall power settings of multiple heating elements. For example, if two heating elements are each set to 6W, for a total of 12W, and one is atomizing normally while the other is above the first resistance threshold but below the second, the power of the atomizing heating element will be adjusted to 7W, and the power of the non-atomizing heating element will be adjusted to 5W to ensure that the overall atomization power and vapor production remain unchanged. If one is atomizing normally while the other is above the second resistance threshold, the power of the atomizing heating element will be adjusted to 8W, and the power of the non-atomizing heating element will be adjusted to 0W to ensure that the atomizing heating element does not burn due to excessive power, while maintaining a certain amount of atomization.

[0121] Under the condition of equal airflow suction in both airways, after the start-up microphone is triggered, both heating elements start up. The MCU detects the resistance value of each heating element before and after start-up in real time. If the resistance values ​​of both heating elements are within the first resistance threshold range, the MCU controls the two heating elements to output power normally.

[0122] In the case of dual-channel unequal airflow suction or single-channel suction, after triggering the start microphone, the dual heating elements start, and the MCU detects the resistance value of each heating element before and after start in real time. If the resistance value of heating element 1 is within the first resistance threshold range, and the resistance value of heating element 2 is between the first resistance threshold and the second resistance threshold, then the MCU increases the power of heating element 1 and decreases or turns off the power output of heating element 2.

[0123] The electronic atomizing device provided in this embodiment can avoid the problem of aerosol accumulation in the non-vaporizing chamber when both chambers are atomized simultaneously during single-airflow channel inhalation (such as single-nostril nasal plugging, single-nostril inhalation, etc.), which leads to excessive condensate and waste of atomizing liquid. By adjusting the power of the two heating elements in real time, the atomized taste is guaranteed to be consistent under different inhalation conditions, thus improving the working reliability of the electronic atomizing device.

[0124] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

[0125] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
