[0019] In order to clarify the purpose, technical solution and advantages of the present application, the present application will be described in detail with reference to the accompanying drawings and examples as follows. Note that the specific examples described in the present specification are only for the purpose of interpreting the present application, and are not intended to limit the present application.

[0020] In one embodiment, as shown in FIG. 1, a method for controlling a microwave heating electronic atomization device is provided, which includes the following steps S300 to S500.

[0021] In step S300, when the microwave heating electronic atomization device heats the atomization medium with microwaves, the current output power and reflected power per unit time are obtained.

[0022] For example, the controller can control the microwave heating device to output microwaves to heat the atomization medium. According to actual needs, the heating process of the microwave heating electronic atomizer can be divided into different stages, and a corresponding reference power range can be set for each stage. For example, according to the user's inhalation action, the heating process of the microwave heating electronic atomizer can be divided into a pre-heating period before the user's first inhalation, a warming period between each inhalation, and a warming period during inhalation. After the inhalation sensing device of the microwave heating electronic atomizer detects the inhalation negative pressure, the controller controls the microwave heating device to operate. In the pre-heating period and the warming period, the controller controls microwave heating based on the range of the reference power stored in advance. In the warming period between each inhalation, the warming period is divided into a number of unit times, and a corresponding initial power is set for each unit time, and the controller continuously controls the operation of the microwave heating device in different unit times to maintain the warming temperature in a stable temperature range. When the current unit time is the first unit time of the warming period, the controller controls the microwave heating device to perform microwave heating with a predetermined initial power as the output power. When the current unit time is the second or subsequent unit time of the warming period, the controller controls the microwave heating device to perform microwave heating based on the optimized output power per current unit time. When microwave heating is performed, the reflected power detection device detects the reflected power per current unit time and feeds it back to the controller.

[0023] In addition, the value per unit time can be set according to the actual application, for example, the unit time can be 1 ms or other time, and the minimum resolution unit per unit time can be 1 μs to 1 s. In other embodiments, the heating process of the microwave heating electronic atomization device can be divided into other different stages, and microwave heating control can be performed according to multiple unit times in one or more of these stages.

[0024] In step S400, a power adjustment coefficient is calculated based on the current output power and reflected power per unit time.

[0025] Specifically, the controller may obtain the output power and the reflected power per current unit time, and then determine a power adjustment factor for optimizing the initial power per next unit time based on the ratio between the reflected power and the output power per current unit time, and adjust the actual power output of the microwave heating electronic atomization device based on the determined power adjustment factor. Alternatively, the controller may determine the power adjustment factor per next unit time by other algorithms based on the reflected power and the output power per current unit time.

[0026] In step S500, the initial power per next unit time is optimized based on the power adjustment coefficient to obtain the output power per next unit time.

[0027] The output power per next unit time is used to heat and control the atomization medium in the next unit time by the microwave heating electronic atomization device. Specifically, after calculating the power adjustment coefficient, the controller can multiply the initial power per next unit time by the power adjustment coefficient to obtain the output power per next unit time, that is, Pnn=K*Pn, n≧2, where K is the power adjustment coefficient, Pn is the initial power per n-th unit time, and Pnn is the output power per n-th unit time. After the next unit time of the warming period is reached, the controller controls the microwave heating device to perform microwave heating based on the calculated output power. It should be noted that in other embodiments, the controller may determine the output power per next unit time in other ways based on the power adjustment coefficient. By detecting the output power and the reflected power in real time during the heating process, the real-time power required for the atomization medium in the heating process can be calculated. Therefore, by controlling and adjusting the output power in real time through the monitoring feedback of the reflected power, the effective control of the inhalation process of the microwave heating electronic atomization device can be realized.

[0028] The above-mentioned method for controlling a microwave heating electronic atomization device detects a current reflected power per unit time, and adjusts and optimizes an initial power per next unit time based on the detected reflected power, thereby realizing effective control of the microwave heating electronic atomization device and improving the control accuracy of the microwave heating electronic atomization device.

[0029] In one embodiment, as shown in FIG. 2, step S400 includes step S410 and step S420.

[0030] In step S410, the controller calculates the ratio between the reflected power and the output power per current unit time to obtain the power ratio. After obtaining the output power and the reflected power per current unit time, the controller calculates the ratio between the reflected power and the output power to obtain the power ratio.

[0031] In step S420, a power adjustment coefficient is calculated based on the power ratio. Similarly, take the controller multiplying the initial power per next unit time by the power adjustment coefficient to obtain the output power per next unit time as an example, the controller can pre-store the corresponding relationship between the power ratio and the power adjustment coefficient, and when determining the power adjustment coefficient based on the power ratio, the larger the power ratio, the more microwave power is not absorbed by the atomization medium, and the power adjustment coefficient can be set smaller, that is, the adjustment range of the output power per next unit time is larger. After calculating the actual power ratio per current unit time, a power adjustment coefficient can be determined to optimize the power per next unit time based on the actual magnitude of the power ratio and the pre-stored corresponding relationship, so that the power output of the microwave heating electronic atomization device is more suited to actual needs.

[0032] Further, in one embodiment, as shown in FIG. 3, step S420 includes step S422 and step S424.

[0033] In step S422, determine the corresponding power adjustment range according to the numerical range located in the power ratio. Specifically, the corresponding relationship between different numerical ranges and power adjustment ranges is established in advance, and the controller can determine the numerical range located in the power ratio after calculating the power ratio, and further determine the corresponding power adjustment range.

[0034] In step S424, obtain a power adjustment coefficient according to the power adjustment range. Different methods of determining the power adjustment range are used to calculate the power adjustment coefficient K. When the power adjustment range increases with the increase of the power ratio, the power adjustment coefficient decreases with the increase of the power adjustment range, and when the power adjustment range decreases with the increase of the power ratio, the power adjustment coefficient increases with the increase of the power adjustment range.

[0035] It should be noted 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 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 / output power P<0.2, the actual power output is reduced by 15%, and 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 is reduced by 25%, and the power adjustment range is 0.25. Therefore, K is (1-0.25)=0.75, i.e., Pnn=0.75*Pn; 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; 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 is reduced by 45%, the power adjustment range is 0.45, and K is (1-0.45)=0.55, i.e., Pnn=0.55*Pn.

[0036] In addition, in one embodiment, the method further includes the step of controlling the microwave heating electronic atomizer to stop working when the power ratio is greater than a predetermined threshold, to avoid the microwave heating device being damaged by the reflected power being too large. The value of the predetermined threshold is not unique, for example, in this embodiment, the predetermined threshold may be set to 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 atomizer stops working.

[0037] In one embodiment, as shown in FIG. 4, the method further includes step S600, in which, when it is detected that the inhalation interval of the microwave heating electronic atomization device is greater than the set threshold, the microwave heating electronic atomization device is controlled to stop. The specific value of the set threshold is not unique and can be set according to actual needs. In this embodiment, the threshold can be set to 90s. The controller can determine the user's inhalation time based on the inhalation negative pressure detected by the inhalation sensing device, and during the warming period of each inhalation interval, the controller monitors the change of the reflected power and adjusts the actual power output in real time. If it is detected that the user's inhalation time interval exceeds the set threshold, it is considered that the user has stopped using the microwave heating electronic atomization device, and at this time, the controller controls the microwave heating device to stop outputting microwaves to avoid energy waste caused by continuous heating.

[0038] In addition, when the inhalation interval of the microwave heating electronic atomization device is greater than the set threshold, the method may further include a step of outputting presentation information. Specifically, the microwave heating electronic atomization device may further include an information presentation device connected to the controller, and the type of the information presentation device is not limited to a unique type, and may be one or more types of a display, an indicator light, and a speaker. When the inhalation interval of the microwave heating electronic atomization device is greater than the set threshold, the controller outputs presentation information by the information presentation device to inform the user that the microwave heating electronic atomization device has stopped operating.

[0039] In one embodiment, continuing to show in FIG. 4, before step S300, the method further includes step S200, in which an initial power per unit time during the warming period of the microwave heating electronic atomization device is determined based on a predetermined power curve.

[0040] In the predetermined power curve, the power value for each time in the preheating period, the warming period, and the temperature rise period of the microwave heating electronic atomization device is set. Specifically, the predetermined power curve is one or more different power curves set according to different types of atomization media. The predetermined power curve includes different time / power values ​​set in the preheating period before the first inhalation of the microwave heating electronic atomization device, the warming period at each inhalation interval, and the temperature rise period at the time of inhalation. The controller performs microwave heating control based on the power data stored corresponding to the predetermined power curve in the preheating period, the warming period, and the temperature rise period. In the warming period, the controller further performs real-time optimization adjustment on the predetermined power curve based on the detected feedback power to ensure accurate stability of the control. In the predetermined power curve, the power range set at different stages can also be set according to the actual situation. In this embodiment, in the predetermined power curve, the power in the preheating period is in the range of 5W to 30W, the power in the warming period is in the range of 0 to 20W, and the power in the temperature rise period is in the range of 5W to 30W.

[0041] Further, in one embodiment, as shown in FIG. 4, before step S200, the method further includes step S100, in which the type of atomization medium is detected, and a predetermined power curve is determined based on the type of atomization medium.

[0042] Specifically, the controller can store corresponding predetermined power curves according to different types of atomization media. The microwave heating electronic atomization device may further include a medium detection device connected to the controller, and after the user puts the atomization medium into the medium insertion port of the microwave heating electronic atomization device, the medium detection device detects the type of the atomization medium, and feeds back the detection result to the controller, and the controller determines the corresponding predetermined power curve according to the detection result. The manner in which the medium detection device detects the type of medium is not unique, and specifically can be realized by multiple methods such as dielectric property detection recognition for the atomization medium, two-dimensional code recognition, and specific mark nameplate recognition.

[0043] In another embodiment, the method further includes receiving a power setting signal, determining the type of atomization medium according to the power setting signal, and determining a predetermined power curve according to the type of atomization medium. In this embodiment, the power setting signal is input manually, so that the controller can determine the corresponding medium type according to the received power setting signal and select the predetermined power curve. The manner of inputting the power setting signal to determine the type of atomization medium is not unique, for example, pressing the start key twice quickly to correspond to medium A, pressing three times quickly to correspond to medium B, pressing once long and pressing once to correspond to medium C, etc.

[0044] In order to better understand the above mentioned microwave heating electronic atomizer control method, the electronic atomizer will be taken as an example for a detailed description below.

[0045] Microwave heating is electromagnetic radiation heating, but the commonly used thermal resistance temperature measurement is easily interfered with in the microwave field, causing signal interference, resulting in inaccurate temperature measurement, and even causing thermal resistance heating or ignition waveguiding phenomena, which not only makes it impossible to perform accurate temperature measurement, but also affects the stability of the microwave field and the normal use of the device, so it is necessary to use other suitable temperature control methods. The temperature control method of the conventional microwave heating non-combustion medium is controlled by a predetermined power / time curve, and the suitability of the power curve has a large uncertainty in the actual inhalation process, so the temperature fluctuates greatly and it is difficult to ensure the consistency of the inhalation feeling.

[0046] Based on the above research and development background, the purpose of this application is to overcome the shortcomings of the prior art, provide a control method suitable for microwave heating electronic atomization devices, and utilize the characteristics of microwave heating to solve the problems that resistance-type temperature measurement is easily interfered with and unstable under microwave heating conditions, so as to realize more accurate control of microwave heating electronic atomization devices, and at the same time, effectively protect the normal and stable use of microwave heating appliances.

[0047] Specifically, during microwave heating, if the output microwave power is not completely absorbed by the heating material, reflected power will be generated, and if the reflected power is too large, it will not only damage the solid-state microwave source and affect its service life, but also cause unnecessary energy loss and increase energy consumption. By adding a reflected power detection device to the solid-state microwave source, the monitoring feedback of the reflected power can be realized, and in the heating process, the output power and the reflected power can be detected in real time, so that the real-time power required by the medium in the heating process can be calculated, and the corresponding temperature of the heated material can be accurately represented. Therefore, by monitoring and feedback of the reflected power, and controlling and adjusting the output power in real time through a certain algorithm logic, the effective control of the inhalation process of the microwave heating electronic atomizer can be realized.

[0048] The control method of the present application uses a predetermined power curve + reflected power detection and adjustment control, and during the inhalation process, monitors the change of reflected power during the inhalation process in real time, and 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 ratio of reflected power / output power 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 atomization media. Specifically, the predetermined power curve is selected by the atomization device through the recognition of different atomization media. The recognition of the atomization medium can be realized by the atomization device through various methods such as the dielectric property detection recognition of the atomization medium, the two-dimensional code recognition, and the specific mark nameplate recognition.

[0050] The predetermined power curve is a different time / power value set based on the pre-heating period before the first inhalation, the warming period between each inhalation, and the warming period during inhalation. In this application, the operating temperature of the microwave heating electronic atomization device is 100°C to 350°C. The inhalation time of each heated non-combustion type atomization medium is 120s to 600s, the time length of the pre-heating period before the first inhalation is 1s to 10s, and the period from after each inhalation to before the next inhalation is the warming period, and the warming time for each is 10s to 90s. Each inhalation process is a warming period, and the time of the warming period is 1s to 5s.

[0051] The microwave heating electronic atomizer according to the present application is provided with an inhalation sensing device, which can accurately detect the start and end of each inhalation and feed back to the controller. When the time for two inhalations exceeds 90s, the microwave heating electronic atomizer stops the microwave output and issues a signal instruction. The operating output power of the microwave heating electronic atomizer is in the range of 0-30W, and the power of 0-30W can be adjusted steplessly, with the minimum adjustable unit being 0.1W. In order to improve the convenience of inhalation, reduce the waiting time for inhalation, and realize rapid atomization of the first inhalation, the rapid heating power at the start is 5W-30W, and thereafter, the predetermined heat retention power is 0-20W, and the inhalation heating power is 5W-30W.

[0052] During the warming period, the controller continuously outputs power P1, P2, ..., Pn based on a predetermined initial power according to time t1, t2, ..., tn, to maintain the warming temperature in a stable temperature range, the minimum resolution unit of unit time t may be 1 μs to 1 s, and the warming temperature is 100 ° C to 250 ° C. In the actual operation process, the controller adjusts and optimizes the predetermined initial power according to the detection feedback of the reflected power, and outputs the predetermined initial power at the first unit time t1 from the start of the warming. The reflected power detection device monitors the reflected power Pr1 of the initial output power P1, and then the controller calculates the ratio of the reflected power (Pr1) / output power (P1), judges the magnitude of the ratio, and determines the actual output power P22 at the next unit time t2. Further, based on the reflected power Pr2 / output power P22 at the unit time t2, the controller determines the actual output power P33 at the next unit time t3, and circulates in order to continuously output the actual output powers P44, P55, ..., Pnn at t4, t5, ..., tn.

[0053] Furthermore, the actual output power Pnn per next unit time is determined based on the ratio of the reflected power (Prn) / output power (Pn) per current unit time, and the determined manner is Pnn=K*Pn, where K is a power adjustment coefficient, the magnitude of its value varies depending on the magnitude of the ratio of the reflected power (Prn) / output power (Pn), and at the same time, also varies depending on the components of the adapted atomization medium.

[0054] Furthermore, the method of determining the actual output power is as follows: if reflected power Pr / output power P<0.1, the power output remains unchanged, i.e. Pnn=Pn(n≧2); if 0.1≦reflected power Pr / output power P<0.2, the actual power output is reduced by 15%, and K is (1-0.15)=0.85, i.e. Pnn=0.85*Pn; if 0.2≦reflected power Pr / output power P<0.3, the power output is reduced by 25%, and K is (1-0.25)=0.75, i.e. Pnn=0.75*Pn. If 0.3≦reflected power Pr / / output power P<0.4, the power output is reduced 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 is reduced 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 nebulizer stops operating.

[0055] The above control method adjusts the actual power output in real time based on both the predetermined power curve and the reflected power monitoring feedback, recognizes different atomization through recognition methods to obtain and determine different predetermined power curves, and performs step-by-step power control for the pre-heating period before the first inhalation, the warming period between each inhalation, and the warming period during inhalation based on the predetermined power curve. At the same time, the corresponding power adjustment coefficient K is determined according to the ratio of reflected power (Pr1) / output power (P1), and the predetermined power curve adjustment optimization control is performed in real time, which effectively realizes system control and improves the safety and service life of the microwave heating electronic atomization device.
