[0029] 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.

[0030] In one embodiment, such as Figure 1 As shown, a control method for a microwave-heated electronic atomization device is provided, comprising:

[0031] Step S300: When the microwave heating electronic atomizing device microwaves the atomizing medium, obtain the output power and reflected power per unit time.

[0032] Specifically, the controller can control the microwave heating device to output microwaves to heat the atomized medium. Depending on the actual needs, the heating process of the microwave-heated electronic atomizing device can be divided into different stages, with corresponding reference power ranges set for each stage. For example, based on the user's inhalation action, the heating process can be divided into a preheating stage for the user's first inhalation, a heat preservation stage between each inhalation, and a temperature rise stage during inhalation. After the inhalation sensor of the microwave-heated electronic atomizing device detects negative pressure, the controller starts the microwave heating device. In the preheating and temperature rise stages, the controller controls the microwave heating according to the pre-saved reference power range. During the heat preservation stage between each inhalation, the heat preservation stage is divided into multiple time units, each with a corresponding initial power setting. The controller continuously controls the microwave heating device to operate at different time units to maintain the heat preservation temperature within a stable temperature range. When the current unit time is the first unit time of the heat preservation period, the controller uses the preset initial power as the output power to control the microwave heating device for microwave heating. When the current unit time is the second or subsequent unit time of the heat preservation period, the controller controls the microwave heating device for microwave heating according to the optimized output power for the current unit time. During microwave heating, the reflected power is detected by a reflected power detection device and fed back to the controller.

[0033] It is understood that the specific value of the unit time is not unique; it can be 1 ms or other durations, and the smallest resolvable unit of unit time can be 1 μs to 1 s. Furthermore, in other embodiments, the heating process of the microwave-heated electronic atomization device can be divided into different stages, and microwave heating control can be performed according to multiple unit times in one or more of these stages.

[0034] Step S400: Calculate the power adjustment coefficient based on the current output power and reflected power per unit time.

[0035] Specifically, after obtaining the output power and reflected power for the current unit time, the controller can determine a power adjustment coefficient for initial power optimization in the next unit time based on the ratio of reflected power to output power for the current unit time, thereby adjusting the actual power output of the microwave-heated electronic atomizing device. Alternatively, the controller can combine the reflected power and output power for the current unit time and use other algorithms to determine the power adjustment coefficient for the next unit time.

[0036] Step S500: Optimize the initial power for the next unit time according to the power adjustment coefficient to obtain the output power for the next unit time.

[0037] The output power in the next unit time is used to control the heating of the atomized medium by the microwave-heated electronic atomizing device in the next unit time. Specifically, after calculating the power adjustment coefficient, the controller can multiply the initial power of the next unit time by the power adjustment coefficient to obtain the output power of the next unit time, i.e.: Pnn = KPn, n ≥ 2, where K is the power adjustment coefficient, Pn is the initial power of the nth unit time, and Pnn is the output power of the nth unit time. When the next unit time of the heat preservation stage is reached, the controller controls the microwave heating device to perform microwave heating according to the calculated output power. It can be understood that in other embodiments, the controller can also determine the output power of the next unit time using other methods based on the power adjustment coefficient. By detecting the output power and reflected power in real time during the heating process, the real-time power required by the atomized medium during the heating process can be calculated. Therefore, by monitoring and adjusting the output power in real time through the feedback of reflected power, effective control of the suction process of the microwave-heated electronic atomizing device can be achieved.

[0038] The control method of the microwave heating electronic atomization device described above adjusts and optimizes the initial power for the next unit time by detecting the reflected power of the current unit time, thereby effectively controlling the microwave heating electronic atomization device and improving the control accuracy of the microwave heating electronic atomization device.

[0039] In one embodiment, such as Figure 2 As shown, step S400 includes steps S410 and S420.

[0040] Step S410: Calculate the ratio of reflected power to output power per unit time to obtain the power ratio. After acquiring the output power and reflected power per unit time, the controller calculates the ratio of reflected power to output power to obtain the power ratio.

[0041] Step S420: Calculate the power adjustment coefficient based on the power ratio. Again, taking the example of the controller multiplying the initial power for the next unit time by the power adjustment coefficient to obtain the output power for the next unit time, the controller can pre-store the correspondence between the power ratio and the power adjustment coefficient. When determining the power adjustment coefficient based on the power ratio, a larger power ratio indicates more microwave power not absorbed by the atomizing medium, thus allowing for a smaller power adjustment coefficient, resulting in a larger adjustment range for the output power in the next unit time. After calculating the actual power ratio for the current unit time, combining the actual power ratio with the pre-stored correspondence, the power adjustment coefficient for power optimization in the next unit time can be determined, making the power output of the microwave-heated electronic atomizing device more in line with actual needs.

[0042] Furthermore, in one embodiment, such as Figure 3 As shown, step S420 includes steps S422 and S424.

[0043] Step S422: Determine the corresponding power adjustment amplitude based on the numerical range of the power ratio. Specifically, a correspondence between different numerical ranges and power adjustment amplitudes can be established in advance. After calculating the power ratio, the controller determines the numerical range in which the power ratio lies, and thus determines the corresponding power adjustment amplitude.

[0044] Step S424: Obtain the power adjustment coefficient based on the power adjustment amplitude. The calculation method for the power adjustment coefficient K will vary depending on how the power adjustment amplitude is determined. If the power adjustment amplitude increases with the increase of the power ratio, the power adjustment coefficient decreases with the increase of the power adjustment amplitude; conversely, if the power adjustment amplitude decreases with the increase of the power ratio, the power adjustment coefficient increases with the increase of the power adjustment amplitude.

[0045] It is understood that the correspondence between the numerical range and the power adjustment amplitude is not unique and can be adjusted according to actual needs. In one embodiment, when the reflected power Pr / output power P < 0.1, the power output remains unchanged, and the power adjustment coefficient K = 1, i.e., Pnn = Pn (n ≥ 2); when 0.1 ≤ reflected power Pr / When the output power P < 0.2, the actual power output decreases by 15%, the power adjustment amplitude is 0.15, and K equals (1-0.15) = 0.85, i.e., Pnn = 0.85Pn; when 0.2 ≤ reflected power Pr / / output power P < 0.3, the power output decreases by 25%, the power adjustment amplitude is 0.25, and K equals (1-0.25) = 0.75, i.e., Pnn = 0.75Pn; when 0.3 ≤ reflected power Pr / / output power P < 0.4, the power output decreases by 35%, the power adjustment amplitude is 0.35, and K equals (1-0.35) = 0.65, i.e., Pnn = 0.65Pn; when 0.4 ≤ reflected power Pr / / output power P < 0.5, the power output decreases by 45%, the power adjustment amplitude is 0.45, and K equals (1-0.45) = 0.55, i.e., Pnn = 0.55Pn.

[0046] Furthermore, in one embodiment, the method further includes: if the power ratio is greater than a preset threshold, controlling the microwave heating electronic atomization device to stop working to avoid damage to the microwave heating device due to excessive reflected power. The preset threshold value is not unique; correspondingly, in this embodiment, the preset threshold is 0.5. When 0.5 ≤ reflected power Pr / output power P, the controller controls the microwave heating device to stop outputting microwaves, and the microwave heating electronic atomization device stops working.

[0047] In one embodiment, such as Figure 4 As shown, the method further includes step S600: if the inhalation interval of the microwave-heated electronic atomizing device is detected to be greater than a set threshold, the microwave-heated electronic atomizing device is controlled to stop working. The specific value of the set threshold is not unique and can be set according to actual needs. In this embodiment, the set threshold is 90s. The controller can determine the user's inhalation time based on the inhalation negative pressure detected by the inhalation sensing device. During the heat preservation section in each inhalation interval, the controller monitors the change in reflected power and adjusts the actual power output in real time. When the user's inhalation time interval is detected to exceed the set threshold, it can be considered that the user has stopped using the microwave-heated electronic atomizing device. At this time, the controller controls the microwave heating device to stop outputting microwaves to avoid energy waste caused by continuous heating.

[0048] Furthermore, when the inhalation interval of the microwave-heated electronic atomizing device exceeds a set threshold, the method may also include a step of outputting a prompt message. Specifically, the microwave-heated electronic atomizing device may also include an information prompting device connected to the controller. The type of information prompting device is not unique; it may be one or more of a display screen, indicator light, and speaker. When the inhalation interval of the microwave-heated electronic atomizing device exceeds the set threshold, the controller also outputs a prompt message through the information prompting device to remind the user to stop the microwave-heated electronic atomizing device from operating.

[0049] In one embodiment, continue to refer to Figure 4 Before step S300, the method further includes step S200: determining the initial power of the microwave heating electronic atomizing device at each unit time during the heat preservation stage according to the preset power curve.

[0050] The preset power curve sets the power values ​​of the microwave-heated electronic atomizing device at different times during the preheating, heat preservation, and heating stages. Specifically, the preset power curve is one or more different power curves matched according to different types of atomizing media. The preset power curve includes different time / power values ​​set for the preheating stage of the microwave-heated electronic atomizing device during the first inhalation, the heat preservation stage between each inhalation, and the heating stage during inhalation. During the preheating, heat preservation, and heating stages, the controller performs microwave heating control according to the power data stored in the corresponding preset power curve. During the heat preservation stage, the controller also optimizes and adjusts the preset power curve in real time based on the detected feedback power to ensure accurate and stable control. The power range set in the preset power curve at different stages can also be set according to the actual situation. In this embodiment, the power range of the preset power curve is 5W-30W for the preheating stage, 0-20W for the heat preservation stage, and 5W-30W for the heating stage.

[0051] Furthermore, in one embodiment, such as Figure 4 As shown, before step S200, the method further includes step S100: detecting the type of atomizing medium and determining a preset power curve based on the type of atomizing medium.

[0052] Specifically, the controller can save corresponding preset power curves for different types of atomizing media. The microwave-heated electronic atomizing device may also include a media detection device connected to the controller. After the user places the atomizing media into the media insertion port of the microwave-heated electronic atomizing device, the media detection device detects the type of the atomizing media and feeds back the detection result to the controller. The controller then determines the corresponding preset power curve based on the detection result. The media detection device can detect the media type in various ways, including by detecting and identifying the dielectric properties of the atomizing media, QR code recognition, or specific label recognition.

[0053] In another embodiment, the method further includes: receiving a power setting signal, determining the type of atomizing medium based on the power setting signal, and determining a preset power curve based on the type of atomizing medium. In this embodiment, the power setting signal can be manually input, and the controller determines the corresponding medium type based on the received power setting signal, thereby selecting the preset power curve. The method of determining the atomizing medium type by inputting the power setting signal is not unique; for example, two quick short presses of the start button correspond to medium A, three quick short presses correspond to medium B, and one long press followed by one short press corresponds to medium C, etc.

[0054] To better understand the control method of the microwave-heated electronic atomization device described above, the following explanation will use an electronic atomization device as an example.

[0055] Microwave heating is a form of electromagnetic radiation heating, and conventionally used resistance temperature detectors (RTDs) are easily interfered with in microwave fields, leading to signal interference, inaccurate temperature measurements, and even RTD overheating or arcing. This not only makes accurate temperature measurement impossible but also affects the stability of the microwave field and the normal operation of the equipment. Therefore, other suitable temperature control methods are needed. Existing methods for temperature control of microwave-heated non-combustible media use preset power / time curves. However, the adaptability of these power curves is highly uncertain during actual suction, resulting in large temperature fluctuations and difficulty in ensuring consistent suction flavor.

[0056] Based on the aforementioned research and development background, the purpose of this application is to overcome the shortcomings of existing technologies and provide a control method suitable for microwave-heated electronic atomization devices. This method utilizes the characteristics of microwave heating to solve problems such as the susceptibility to interference and instability of resistance temperature measurement under microwave heating conditions, thereby achieving more precise control of the microwave-heated electronic atomization device. Simultaneously, it effectively protects the normal and stable operation of microwave heating appliances.

[0057] Specifically, during microwave heating, when the output microwave power cannot be completely absorbed by the heated material, reflected power is generated. Excessive reflected power not only damages the solid-state microwave source, affecting its lifespan, but also causes unnecessary energy loss and increases energy consumption. Adding a reflected power detection device to the solid-state microwave source allows for the monitoring and feedback of reflected power. By detecting the output and reflected power in real time during the heating process, the real-time power required by the medium can be calculated, correspondingly providing a more accurate representation of the temperature of the heated material. Therefore, by monitoring and feeding back the reflected power, and then adjusting the output power in real time through a specific algorithm, effective control of the suction process in a microwave-heated electronic atomization device can be achieved.

[0058] The control method provided in this application adopts a preset power curve + reflected power detection and adjustment control. During the suction process, the change of reflected power is monitored in real time. The controller then adjusts the actual power output in real time according to the real-time reflected power value, the ratio of reflected power to output power, or other algorithms, and optimizes the preset power curve in real time to ensure the accuracy and stability of the control.

[0059] A preset power curve is one or more different power curves pre-matched to different atomizing media. The selection of a specific preset power curve is accomplished by the atomizing device identifying different atomizing media. The atomizing media can be identified through various methods, such as dielectric property detection, QR code recognition, or specific label recognition.

[0060] The preset power curve is based on different time / power values ​​set for the preheating section of the first intake, the heat preservation section between each intake, and the heating section during intake. In this application, the operating temperature of the microwave-heated electronic atomizing device is 100℃-350℃. The intake time for each heated non-combustible atomizing medium is 120s-600s. The preheating section of the first intake lasts 1s-10s, and the heat preservation section lasts 10s-90s from the end of each intake to the beginning of the next intake. Each intake process is the heating section, which lasts 1s-5s.

[0061] The microwave-heated electronic atomizing device provided in this application is equipped with a suction sensor that accurately senses the start and end of each inhalation and feeds back to the controller. When the inhalation time for two inhalations exceeds 90 seconds, the microwave-heated electronic atomizing device stops outputting microwaves and issues a signal indication. The operating output power range of the microwave-heated electronic atomizing device is 0-30W, and it can be infinitely adjusted from 0-30W, with a minimum adjustable unit of 0.1W. Specifically, to improve suction convenience, reduce suction waiting time, and achieve rapid atomization of the first inhalation, the initial rapid heating power is 5W-30W, followed by a preset heat preservation power of 0-20W and a suction heating power of 5W-30W.

[0062] During the heat preservation phase, the controller continuously outputs power P1, P2, ..., Pn according to the preset initial power at time intervals t1, t2, ..., tn to maintain the heat preservation temperature within a stable temperature range. The minimum resolution unit of unit time t can be 1μs-1s, and the heat preservation temperature is between 100℃ and 250℃. In actual operation, the controller adjusts and optimizes the preset initial power through the detection feedback of reflected power. At the beginning of the heat preservation phase, the controller outputs the preset initial power at the first unit time t1. After the reflected power detection device monitors the reflected power Pr1 of the initial output power P1, the controller calculates the ratio of reflected power (Pr1) to output power (P1), and then determines the actual output power P22 for the next unit time t2 based on the magnitude of the ratio. Then, based on the reflected power Pr2 / output power P22 at unit time t2, the controller determines the actual output power P33 for the next unit time t3, and so on, continuously outputting the actual output power P44, P55, ..., Pnn for t4, t5, ..., tn.

[0063] Furthermore, the actual output power Pnn in the next unit time is determined based on the ratio of the reflected power (Prn) / output power (Pn) in the current unit time. The method for determination is Pnn = KPn, where K is the power adjustment coefficient. Its value varies depending on the ratio of reflected power (Prn) / output power (Pn) and also varies depending on the composition of the atomizing medium.

[0064] Furthermore, the actual output power is determined as follows: when the reflected power Pr / output power P < 0.1, the power output remains constant, i.e., Pnn = Pn (n ≥ 2); when 0.1 ≤ reflected power Pr / output power P When the power is less than 0.2, the actual power output decreases by 15%, and K equals (1-0.15) = 0.85, i.e., Pnn = 0.85Pn; when 0.2 ≤ reflected power Pr / / output power P < 0.3, the power output decreases by 25%, and K equals (1-0.25) = 0.75, i.e., Pnn = 0.75Pn; when 0.3 ≤ reflected power Pr / / output power P < 0.4, the power output decreases by 35%, and K equals (1-0.35) = 0.65, i.e., Pnn = 0.65Pn; when 0.4 ≤ reflected power Pr / / output power P < 0.5, the power output decreases by 45%, and K equals (1-0.45) = 0.55, i.e., Pnn = 0.55Pn; when 0.5 ≤ reflected power Pr / output power P, the power output stops, and the atomizing device stops working.

[0065] The above control method adjusts the actual power output in real time based on a preset power curve and feedback from reflected power monitoring. It identifies different atomization methods to obtain and determine different matching preset power curves. Based on these preset power curves, segmented power control is applied to the preheating section of the first inhalation, the heat preservation section between each inhalation, and the heating section during inhalation. Simultaneously, the corresponding power adjustment coefficient K is determined by the ratio of reflected power (Pr1) to output power (P1) for real-time optimization control of the preset power curve. This effectively improves the safety and lifespan of the microwave-heated electronic atomization device while achieving system control.
