Best Mode for Carrying Out the Invention
[0019] To make the object, technical solution and advantages of the present application clearer, the present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the specific embodiments described in this specification are only for interpreting the present application and not for limiting the present application.
[0020] In one embodiment, as shown in FIG. 1, a control method for a microwave heating electronic atomization device is provided, including the following steps S300 to S500.
[0021] In step S300, when the microwave heating electronic atomization device heats the atomization medium by microwave, the output power and reflection power per current unit time are obtained.
[0022] For example, a controller can control the microwave heating device to output microwaves and heat the atomizing medium. Depending on the actual needs, the heating process of the microwave heating electron atomizer can be divided into different stages, and a corresponding reference power range can be set for each stage. For example, depending on the user's inhalation operation, the heating process of the microwave heating electron atomizer can be divided into a preheating period before the user's first inhalation, a heat retention period between each inhalation, and a heat rise period during inhalation. After the inhalation sensing device of the microwave heating electron atomizer detects the inhalation negative pressure, the controller controls the operation of the microwave heating device. During the preheating and heat rise periods, the controller performs microwave heating control based on a pre-stored reference power range. During the heat retention period between each inhalation, the heat retention period is divided into multiple unit time intervals, and a corresponding initial power is set for each unit time interval. The controller continuously controls the operation of the microwave heating device at different unit time intervals to maintain the heat retention temperature within a stable temperature range. If the current unit time is the first unit time of the heating period, the controller controls the microwave heating device to perform microwave heating with a predetermined initial power as the output power. If the current unit time is the second or subsequent unit time of the heating period, the controller controls the microwave heating device to perform microwave heating based on the optimized output power per unit time of the current unit time. When performing microwave heating, the reflected power detection device detects the reflected power per unit time of the current unit time and feeds it back to the controller.
[0023] Furthermore, the value per unit time can be set according to the actual application. For example, the unit time may be 1 ms or other times, and the minimum resolution unit per unit time may be 1 μs to 1 s. In other embodiments, the heating process of the microwave heating electron atomizer may be divided into other different stages, and microwave heating control may be performed in one or more of these stages according to multiple unit times.
[0024] In step S400, the power adjustment coefficient is calculated based on the current output power and reflected power per unit time.
[0025] Specifically, the controller may, after obtaining the current output power and reflected power per unit time, determine a power adjustment coefficient to optimize the initial power per unit time for the next unit time based on the current ratio of reflected power to output power per unit time, and adjust the actual power output of the microwave heating electron atomizer based on the determined power adjustment coefficient. Alternatively, the controller may determine the power adjustment coefficient for the next unit time using another algorithm based on the current reflected power and output power per unit time.
[0026] In step S500, the initial power per unit time is optimized based on the power adjustment coefficient to obtain the output power per unit time.
[0027] The next output power per unit time is controlled by the microwave heating electron atomizer to heat the atomizing medium in the next unit time. Specifically, after calculating the power adjustment coefficient, the controller can obtain the output power per unit time by multiplying the initial power per unit time by the power adjustment coefficient, i.e., Pnn = K * Pn, n ≥ 2, where K is the power adjustment coefficient, Pn is the initial power per nth unit time, and Pnn is the output power per nth unit time. After reaching the next unit time of the heat retention period, the controller controls the microwave heating device to perform microwave heating based on the calculated output power. In other embodiments, the controller may determine the output power per unit time in other ways 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 for the atomizing medium during the heating process can be calculated. Therefore, by controlling and adjusting the output power in real time through monitoring feedback of reflected power, effective control of the suction process of the microwave heating electron atomizer can be achieved.
[0028] The control method for the microwave heating electron atomizer described above detects the current reflected power per unit time and optimizes the initial power per unit time for the next unit time based on the detected reflected power, thereby achieving effective control of the microwave heating electron atomizer and improving the control accuracy of the microwave heating electron atomizer.
[0029] In one embodiment, as shown in Figure 2, step S400 includes steps S410 and S420.
[0030] In step S410, the power ratio is obtained by calculating the current ratio of reflected power to output power per unit time. The controller obtains the current output power and reflected power per unit time, and then calculates the ratio of reflected power to output power to obtain the power ratio.
[0031] In step S420, the power adjustment coefficient is calculated based on the power ratio. Similarly, taking the example that the controller multiplies the initial power per unit time by the power adjustment coefficient to obtain the output power per 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 that more microwave power is not absorbed by the atomizing medium, and the power adjustment coefficient can be set smaller, i.e., the adjustment range of the output power per unit time is larger. After calculating the current actual power ratio per unit time, the power adjustment coefficient can be determined to optimize the power per unit time so that the power output of the microwave heating electron atomizer better matches the actual needs, based on the actual magnitude of the power ratio and the pre-stored correspondence.
[0032] Furthermore, in one embodiment, as shown in Figure 3, step S420 includes steps S422 and S424.
[0033] In step S422, the corresponding power adjustment range is determined based on the numerical interval located in the power ratio. Specifically, by pre-establishing the correspondence between different numerical intervals and power adjustment ranges, the controller can calculate the power ratio, determine the numerical interval located in the power ratio, and then determine the corresponding power adjustment range.
[0034] In step S424, the power adjustment coefficient is obtained based on the power adjustment range. The calculation method for the power adjustment coefficient K differs depending on the different methods used to determine the power adjustment range. When the power adjustment range increases with increasing power ratio, the power adjustment coefficient decreases with increasing power adjustment range, and when the power adjustment range decreases with increasing power ratio, the power adjustment coefficient increases with increasing power adjustment range.
[0035] Note that the correspondence between the numerical interval and the power adjustment range is not unique and can be adjusted according to actual needs. In one embodiment, when reflected power Pr / output power P < 0.1, the power output does not change, the power adjustment coefficient K = 1, i.e., Pnn = Pn (n ≥ 2). When 0.1 ≤ reflected power Pr / output power P < 0.2, the actual power output decreases by 15%, the power adjustment range is 0.15, K is (1 - 0.15) = 0.85, i.e., Pnn = 0.85 * Pn. When 0.2 ≤ reflected power Pr / / output power P < 0.3, the power output decreases by 25%, and the power adjustment range is 0.25. Furthermore, K is (1-0.25)=0.75, that is, Pnn=0.75*Pn, and if 0.3≦reflected power Pr / / output power P<0.4, the power output is reduced by 35%, and the power adjustment range is 0.35, and K is (1-0.35)=0.65, that is, Pnn=0.65*Pn, and if 0.4≦reflected power Pr / / output power P<0.5, the power output is reduced by 45%, and the power adjustment range is 0.45, and K is (1-0.45)=0.55, that is, Pnn=0.55*Pn.
[0036] In one embodiment, the method further includes the step of controlling the microwave heating electron atomizer to stop operation if the power ratio is greater than a predetermined threshold, thereby avoiding damage to the microwave heating device due to excessive reflected power. The value of the predetermined threshold is not unique; for example, in this embodiment, the predetermined threshold may be set to 0.5. If 0.5 ≤ reflected power Pr / output power P, the controller controls the microwave heating device to stop the microwave output, and the microwave heating electron atomizer stops operating.
[0037] In one embodiment, as shown in Figure 4, the method further includes step S600, in which the microwave heating electron atomizer is controlled to stop if it is detected that the suction interval of the microwave heating electron atomizer is greater than a set threshold. The specific value of the set threshold is not unique and can be set according to actual needs. In this embodiment, the threshold may be set to 90s. The controller can determine the user's suction time based on the suction negative pressure detected by the suction sensing device, and during the warming period of each suction interval, the controller monitors the change in reflected power and adjusts the actual power output in real time. If it is detected that the user's suction time interval exceeds the set threshold, it is assumed that the user has stopped using the microwave heating electron atomizer, and at this time the controller controls the microwave heating device to stop the microwave output to avoid energy waste due to continuous heating.
[0038] Furthermore, if the suction interval of the microwave heating electron atomizer is greater than a set threshold, the method may further include a step of outputting information. Specifically, the microwave heating electron atomizer may further include an information display device connected to the controller, and the type of information display device is not unique, but may be one or more of a display, indicator light, and speaker. If the suction interval of the microwave heating electron atomizer is greater than a set threshold, the controller outputs information via the information display device to inform the user that the microwave heating electron atomizer has stopped operating.
[0039] In one embodiment, as shown in Figure 4, prior to step S300, the method further includes step S200, in which the initial power per unit time during the heat retention period of the microwave heating electron atomizer is determined based on a predetermined power curve.
[0040] In a predetermined power curve, the power values for each hour during the preheating, holding, and heating periods of the microwave heating electron atomizer are set. Specifically, the predetermined power curve is one or more different power curves set according to different types of atomizing media. The predetermined power curve includes different time / power values set for the preheating period before the first inhalation of the microwave heating electron atomizer, the holding period between each inhalation, and the heating period during inhalation. The controller performs microwave heating control based on the power data stored corresponding to the predetermined power curve during the preheating, holding, and heating periods, respectively. During the holding period, the controller further performs real-time optimization adjustments to the predetermined power curve based on detected feedback power to ensure accurate stability of the control. In the predetermined power curve, the power ranges set at different stages can also be set according to the actual situation. In this embodiment, in the predetermined power curve, the power during the preheating period is in the range of 5W to 30W, the power during the holding period is in the range of 0 to 20W, and the power during the heating period is in the range of 5W to 30W.
[0041] Furthermore, in one embodiment, as shown in Figure 4, prior to step S200, the method further includes step S100, in which the type of atomizing medium is detected and a predetermined power curve is determined based on the type of atomizing medium.
[0042] Specifically, the controller can store corresponding predetermined power curves based on different types of atomizing media. The microwave heating electron atomizer may further include a media detection device connected to the controller. After the user places the atomizing media into the media inlet of the microwave heating electron atomizer, the media detection device detects the type of atomizing media, feeds the detection result back to the controller, and the controller determines a corresponding predetermined power curve based on the detection result. The method by which the media detection device detects the type of media is not unique and can be implemented by multiple methods, specifically such as dielectric property detection and recognition of the atomizing media, two-dimensional code recognition, and recognition of specific markings on nameplates.
[0043] In another embodiment, the method further includes the steps of receiving a power setting signal, determining the type of atomizing medium based on the power setting signal, and determining a predetermined power curve based on the type of atomizing medium. In this embodiment, by manually inputting a power setting signal, the controller can determine the corresponding medium type and select a predetermined power curve based on the received power setting signal. The method of inputting the power setting signal to determine the type of atomizing medium is not unique; for example, pressing the start key twice quickly corresponds to medium A, pressing it three times quickly corresponds to medium B, and pressing it once and then once short-press corresponds to medium C.
[0044] To better understand the control method of the microwave heating electron atomization device described above, the electron atomization device will be explained in detail below as an example.
[0045] Microwave heating is electromagnetic radiation heating, but the commonly used thermal resistance temperature measurement method is susceptible to interference in the microwave field, causing signal interference and inaccurate temperature measurements. This can lead to thermal resistance heating or ignition waveguide phenomena, making accurate temperature measurement impossible and affecting the stability of the microwave field and the normal operation of the equipment. Therefore, it is necessary to use other appropriate temperature control methods. Conventional microwave heating methods for non-combustible media control the temperature using a predetermined power / time curve. However, the suitability of the power curve is highly uncertain during the actual inhalation process, resulting in large temperature fluctuations and making it difficult to guarantee consistency in inhalation sensation.
[0046] Based on the background of the above-mentioned research and development, the objective of this application is to overcome the shortcomings of the prior art and provide a control method applicable to microwave heating electron atomizers. By utilizing the characteristics of microwave heating, it is possible to solve problems such as resistance temperature measurement being susceptible to interference and unstable under microwave heating conditions, thereby enabling more accurate control of microwave heating electron atomizers. At the same time, it is possible to effectively protect the normal and stable operation of microwave heating equipment.
[0047] Specifically, during microwave heating, if the output microwave power is not completely absorbed by the heated material, reflected power is generated. If the reflected power is too high, it can damage the solid microwave source, affecting its lifespan and causing unnecessary energy loss, thus increasing energy consumption. By adding a reflected power detection device to the solid microwave source, reflected power monitoring and feedback can be achieved. By detecting the output power and reflected power in real time during the heating process, the real-time power required for the medium during the heating process can be calculated, and the corresponding temperature of the heated material can be accurately represented accordingly. Therefore, by monitoring and feedback of reflected power and controlling and adjusting the output power in real time using a certain algorithmic logic, effective control of the suction process of the microwave heating electron atomizer can be achieved.
[0048] The control method according to the present invention uses a predetermined power curve + reflected power detection and adjustment control to monitor changes in reflected power during the intake process in real time. The controller adjusts the actual power output in real time based on the magnitude of the real-time reflected power value, the magnitude of the reflected power / output power ratio, or other algorithms, and performs real-time optimization adjustment to the predetermined power curve to ensure accurate stability of the control.
[0049] The predetermined power curve is one or more different power curves set according to different atomizing media. Specifically, the predetermined power curve is selected by the atomizing device's recognition of different atomizing media. Recognition of the atomizing media can be achieved by various methods such as dielectric property detection and recognition of the atomizing media by the atomizing device, two-dimensional code recognition, and recognition of specific markings on nameplates.
[0050] The predetermined power curve is a different time / power value set based on the preheating period before the first inhalation, the heat retention period between each inhalation, and the heat rise period during inhalation. In this application, the operating temperature of the microwave heating electron atomizer is 100°C to 350°C. The inhalation time for each heated non-combustible atomizing medium is 120s to 600s, the length of the preheating period before the first inhalation is 1s to 10s, and thereafter, the period from after each inhalation to before the next inhalation is the heat retention period, with each heat retention period being 10s to 90s. Each inhalation process is a heat rise period, with a heat rise period duration of 1s to 5s.
[0051] The microwave heating electron atomizer according to this application is equipped with an inhalation sensing device that can accurately sense the start and end of each inhalation and provide feedback to the controller. If the two inhalation times exceed 90 seconds, the microwave heating electron atomizer stops the microwave output and issues a signal. The operating output power of the microwave heating electron atomizer is in the range of 0 to 30 W, and the power can be adjusted steplessly from 0 to 30 W, with the smallest adjustable unit being 0.1 W. To improve the convenience of inhalation, reduce the waiting time for inhalation, and achieve rapid atomization for the first inhalation, the rapid heating power at startup is 5 W to 30 W, thereafter the predetermined heat retention power is 0 to 20 W, and the inhalation heating power is 5 W to 30 W.
[0052] During the heating period, the controller continuously outputs powers P1, P2, ..., Pn according to predetermined initial powers according to times t1, t2, ..., tn, thereby maintaining the heating temperature within a stable temperature range. The minimum resolution unit of unit time t may be 1 μs to 1 s, and the heating temperature is 100°C to 250°C. In the actual operation, the controller adjusts and optimizes a predetermined initial power through reflected power detection feedback, outputs the predetermined initial power at the first unit time t1 from the start of heating, the reflected power detection device monitors the reflected power Pr1 of the initial output power P1, and then the controller calculates the ratio of reflected power (Pr1) / output power (P1), determines the magnitude of the ratio, and determines the actual output power P22 for the next unit time t2. Furthermore, based on the reflected power Pr2 / output power P22 for unit time t2, the controller determines the actual output power P33 for the next unit time t3, and so on, cyclically outputting the actual output powers P44, P55, ..., Pnn for t4, t5, ..., tn in succession.
[0053] Furthermore, the actual output power Pnn per unit time is determined based on the current ratio of reflected power (Prn) / output power (Pn) per unit time, using the formula Pnn = K * Pn, where K is the power adjustment coefficient, the magnitude of which depends on the ratio of reflected power (Prn) / output power (Pn) and simultaneously on the components of the adapted atomizing medium.
[0054] Furthermore, the method for determining the actual output power is as follows: When reflected power Pr / output power P < 0.1, the power output does not change, i.e., Pnn = Pn (n ≥ 2). When 0.1 ≤ reflected power Pr / output power P < 0.2, the actual power output decreases by 15%, K is (1 - 0.15) = 0.85, i.e., Pnn = 0.85 * Pn. When 0.2 ≤ reflected power Pr / / output power P < 0.3, the power output decreases by 25%, K is (1 - 0.25) = 0.75, i.e., Pnn = 0.75 * Pn Therefore, if 0.3 ≤ reflected power Pr / / output power P < 0.4, the power output decreases by 35%, and K is (1 - 0.35) = 0.65, i.e., Pnn = 0.65 * Pn. If 0.4 ≤ reflected power Pr / / output power P < 0.5, the power output decreases by 45%, and K is (1 - 0.45) = 0.55, i.e., Pnn = 0.55 * Pn. If 0.5 ≤ reflected power Pr / / output power P, the power output is stopped, and the atomizer stops operating.
[0055] The above control method adjusts the actual power output in real time based on both a predetermined power curve and reflected power monitoring feedback. It recognizes different atomizations using a recognition method, acquires and determines different predetermined power curves, and performs stepwise power control based on the predetermined power curve for the preheating period before the first inhalation, the warming period between each inhalation, and the heating period during inhalation. Simultaneously, it determines the corresponding power adjustment coefficient K based on the ratio of reflected power (Pr1) to output power (P1), and performs predetermined power curve adjustment optimization control in real time, effectively realizing system control and improving the safety and service life of the microwave heating electron atomizer.
[0056] Based on a similar inventive concept, embodiments of the present application further provide a control device for a microwave heating electron atomizer that realizes the control method for the microwave heating electron atomizer described above. Since the means for solving the problem provided by the device are similar to the means for solving the problem described in the above method, specific limitations in the embodiments of one or more control devices for microwave heating electron atomizers provided below can be made by referring to the above limitations for the control method for microwave heating electron atomizers, and are therefore omitted from this explanation.
[0057] In one embodiment, as shown in Figure 5, a control device for a microwave heating electron atomizer is further provided, including a data acquisition module 100, a data processing module 200, and a power optimization module 300.
