Description

[0001] This invention patent application is a divisional application of the invention patent application with application number CN202110201080.7, application date February 23, 2021, and invention title "Resonance Control Circuit and Resonance Control Method Thereof, Electronic Atomization Device". Technical Field

[0002] This application relates to the field of electronic circuit technology, and in particular to resonant control circuits and their resonant control methods, and electronic atomization devices. Background Technology

[0003] The resonant control circuit in existing electronic atomizing devices is usually simple in structure, consisting of a heating resistor, insulating components, positive and negative electrodes, a power supply, and a controller. Users control the voltage applied to the heating resistor and the presence or absence of current flowing through the heating resistor by turning the power supply on and off, thereby controlling whether the heating resistor is energized and heated.

[0004] However, with such a resonant control circuit, the same heating resistor will be continuously heated during power-on, resulting in a single, unchanging form of the heated working substance, lacking diversity, and easily causing localized carbon buildup in the heating module, shortening its lifespan. Furthermore, the localized carbon buildup in the heating module can cause impurities from the carbon deposits to be mixed into the heated or atomized working substance, affecting the user experience.

[0040] This application provides a resonant control circuit and its resonant control method, as well as an electronic atomizing device. It can use a multi-channel capacitor-inductor resonant circuit to select the appropriate operating frequency band to resonate and heat the heating resistor according to different needs, thereby meeting the diverse needs of users, reducing local carbon buildup near the heating resistor, extending the life of the electronic atomizing device, and improving the user experience.

[0041] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.

[0042] A capacitor-inductor resonant circuit consists of an inductor (L) and a capacitor (C) connected together. This circuit can be used as an electrical resonator to store the energy of vibrations during circuit resonance. Capacitor-inductor circuits are used both to generate signals of specific frequencies and to separate signals of specific frequencies from more complex signals, and are widely used in frequency band selection.

[0043] Please see Figure 1 , Figure 1 This is a schematic diagram of the module structure of a resonant control circuit in an embodiment of this application. Figure 1 As shown, the resonant control circuit in this embodiment includes a controller 101, a capacitor-inductor resonant module 102, a heating module 103, and a power supply 104.

[0044] One end of the controller 101 is connected to one end of the capacitor-inductor resonant module 102, and is used to select different operating frequency bands according to different input signals to control the capacitor-inductor resonant module 102 to generate different resonances.

[0045] The power supply 104 is connected to the other end of the controller 101 and to one end of the capacitor-inductor resonant module 102, and is used to provide power voltage to the controller 101 and the capacitor-inductor resonant module 102.

[0046] One end of the heating module 103 is connected to the other end of the capacitor-inductor resonant module 102, and the other end of the heating module 103 is connected to the power supply 104, which is used to resonate and heat the working substance according to the different resonances generated by the capacitor-inductor resonant module 102.

[0047] Furthermore, the capacitor-inductor module 102 may include at least one capacitor and at least one inductor, and the heating module 103 may include at least two heating resistors, without specific limitations here. That is, the capacitor-inductor module 102 may include two capacitors and one inductor, or it may include three capacitors and two inductors, or it may include one capacitor and two inductors, or it may include two capacitors and three inductors, without specific limitations here.

[0048] It should be noted that the working substance in the embodiments of this application can be a medical drug, herbal extract, e-liquid, or e-cigarette paste, and there is no specific limitation here.

[0049] In this embodiment, the controller in the resonant control circuit selects different operating frequency bands according to different input signals to control the capacitor-inductor resonant module to generate different resonances, and causes the heating module to perform different resonant heating on the working substance according to different resonances. This allows the working substance to be heated or atomized in different ways under different conditions, resulting in a variety of forms of the heated working substance to meet the diverse needs of users. Furthermore, since the heating module is not always in a heated state or not always in the same heated state when powered on, the generation of local carbon deposits on the heating module can be reduced, thereby extending the life of the heating module. In addition, it can also reduce the impurities that are introduced into the working substance due to local carbon deposits, improving the purity of the heated working substance and the user experience.

[0050] The above describes the module structure of a resonant control circuit in an embodiment of this application.

[0051] In this embodiment, the resonant control circuit may include two connection methods, which are as follows: (a) A connection method in which the heating resistor is connected to the inductor and the capacitor is connected to the AC voltage switch; (ii) A connection method in which the heating resistor is connected to the capacitor and the inductor is connected to the AC voltage switch.

[0052] The two connection methods described above are described below.

[0053] (a) Circuit connection method in which the heating resistor is connected to the inductor and the capacitor is connected to the AC voltage switch; In this application embodiment, this connection method can be further divided into two different circuit structure embodiments. The first circuit structure embodiment can be a circuit structure in which the number of heating resistors R and the number of inductors L are the same. The second circuit structure embodiment can be a circuit structure in which the number of inductors L is less than the number of heating resistors R. The following describes these two specific circuit structures in detail.

[0054] First circuit structure embodiment: In this embodiment, when the number of heating resistors R and the number of inductors L in the resonant control circuit are the same, one end of each heating resistor R is connected to one end of an inductor L, the other end of each heating resistor R is connected to a power supply, and the other end of each inductor L is connected to the first node A. The operating frequency bands of each inductor L are different.

[0055] The first node A is connected to one end of at least two capacitors, and the other end of each of the at least two capacitors C is connected to one end of their respective AC voltage switches K. The number of AC voltage switches K is the same as the number of capacitors C.

[0056] The other end of the AC voltage switch K is connected to the power supply and the controller. The capacitor C can resonate with the inductor L, which operates in the corresponding frequency band, according to the operating frequency band selected by the controller, so that the corresponding heating resistor R resonates and heats the working substance.

[0057] Specifically, please see Figure 2 , Figure 2 This is a circuit connection diagram of a resonant control circuit in an embodiment of this application. Figure 2 It can be seen that the resonant control circuit includes a controller 201, a voltage-inductance resonant module 202, a heating module 203, and a power supply 204.

[0058] In this embodiment, the number of heating resistors R and inductors L in the resonant control circuit is the same, including two heating resistors R1 and R2 in the heating module 203, two inductors L1 and L2 in the voltage-inductance resonant module 202, and three capacitors C. The capacitors C include a first capacitor C1, a second capacitor C2, and a third capacitor C3. The AC voltage switches include a first AC voltage switch K1, a second AC voltage switch K2, and a third AC voltage switch K3. The inductors include a first inductor L1 and a second inductor L2. One end of the first inductor L1 and one end of the second inductor L2 are respectively connected to one of the two heating resistors R, and the other ends of the first inductor L1 and the second inductor L2 are respectively connected to the first node A.

[0059] With the first AC voltage switch K1 turned on and the second AC voltage switch K2 and the third AC voltage switch K3 both turned off, the first capacitor C1 and the first inductor L1 are configured to resonate within a first preset operating frequency band, causing the heating resistor R1 connected to the first inductor L1 to resonate and heat the e-liquid. Simultaneously, since the operating frequency band of the second inductor L2 is different from that of the first capacitor C1, the second inductor L2 will not resonate with the first capacitor C1, and therefore, the second inductor L2 is not operating. Consequently, the heating resistor R2 connected to the second inductor L2 will not resonate and heat the e-liquid.

[0060] It should be noted that, as an example, the working substance in this embodiment is e-liquid.

[0061] With the second AC voltage switch K2 turned on and both the first AC voltage switch K1 and the third AC voltage switch K3 turned off, the second capacitor C2 and the second inductor L2 are configured to resonate within a second preset operating frequency band. This causes the heating resistor R2 connected to the second inductor L2 to resonate and heat the e-liquid. Simultaneously, since the operating frequency band of the first inductor L1 is different from that of the second capacitor C1, the first inductor L1 will not resonate with the second capacitor C2. Therefore, the first inductor L1 is not operating, and consequently, the heating resistor R1 connected to the first inductor L1 will not resonate and heat the e-liquid.

[0062] When the third AC voltage switch K3 is turned on and the first AC voltage switch K1 and the second AC voltage switch K2 are both turned off, the third capacitor C3, the first inductor L1 and the second inductor L2 are configured to resonate together in the third preset operating frequency band, so that the heating resistors R1 and R2 resonate and heat the e-liquid together.

[0063] It should be noted that the third preset operating frequency band is the frequency band that overlaps with the first preset operating frequency band and the second preset operating frequency band.

[0064] For example, if the first preset operating frequency band is 40-80 Hz and the second preset operating frequency band is 60-100 Hz, then the third preset operating frequency band can be 60-80 Hz. In this case, when the third AC voltage switch K3 is turned on, although the first AC voltage switch K1 and the second AC voltage switch K2 are both turned off, since the third preset operating frequency band is located in the overlapping part of the first and second preset operating frequency bands, the first inductor L1 and the second inductor L2 can resonate with the third capacitor C3 at this time. This allows the heating resistors R1 and R2 to resonate and heat the e-liquid through the heat generated by the induced capacitor-inductance resonance.

[0065] It should be noted that the power supply mentioned above in the embodiments of this application may include an AC power supply, which is used to provide a power supply that causes the capacitor C and the inductor L to resonate in the corresponding operating frequency band.

[0066] Specifically, Figure 2The resonant control circuit shown may include only a first AC voltage switch K1, a second AC voltage switch K2, and a third AC voltage switch K3. The controller 201 determines which AC voltage switch to turn on based on the different input signals received, so that a group of capacitors C and inductors L connected to the turned-on AC voltage switches resonate within the corresponding preset operating frequency band. This causes the heating resistor R in the group to resonate and heat the e-liquid. Since the input signals and the corresponding preset operating frequency bands are different, the resulting resonances are also different, and the flavor effects of the e-liquid produced by the resonant heating are also different.

[0067] In this embodiment, the capacitor C and inductor L resonate, which not only enables the heating resistors R1 and R2 to resonate and heat, but also shakes off the local carbon deposits attached to the heating resistors R1 and R2 due to the resonant vibration. This reduces the local carbon deposits on the heating resistors R1 and R2, thereby reducing the carbon impurities emitted with the atomized e-liquid vapor, improving the taste of the atomized e-liquid vapor, and extending the service life of the heating resistors R1 and R2 as well as the e-cigarette device equipped with the heating resistors. In addition, since the controller can control the conduction and disconnection of the first AC voltage switch K1, the second AC voltage switch K2, and the third AC voltage switch K3 according to the received input signal, it can control each heating resistor to resonate and heat the e-liquid at different operating frequencies. This allows the heated or atomized e-liquid to produce different tastes, meeting the experience needs of different users. Moreover, it allows each heating resistor to work alternately within different preset time periods, instead of working continuously, thus reducing the workload of the heating resistors and further improving the performance of the heating resistors and the e-cigarette device equipped with them, extending their service life.

[0068] Furthermore, the power supply in the embodiments of this application may also include a DC power supply, which is used to provide power for directly energizing the heating resistors R1 and R2 and performing non-resonant heating on the working substance.

[0069] The first node A is connected to one end of at least one DC voltage switch K, and the other end of the DC voltage switch K is connected to a DC power supply and a controller respectively.

[0070] In this embodiment, specifically, as follows: Figure 2 As shown, the first node A is connected to one end of a DC voltage switch K4, and the other end of the DC voltage switch K4 is connected to a DC power supply and a controller. That is to say, Figure 2 The power supply 204 shown may include only AC power supply or DC power supply, or it may include both AC power supply and DC power supply.

[0071] Figure 2In the process, when the DC voltage switch is turned on, the first inductor L1 and the second inductor L2 can transmit the DC voltage U4 to the heating resistors R1 and R2 respectively, so that the heating resistors R1 and R2 can directly heat the e-liquid without resonance.

[0072] In this embodiment, please refer to Figure 3 , Figure 3 This is a voltage waveform generated by a resonant control circuit in an embodiment of this application. The horizontal axis represents time T, and the vertical axis represents voltage U. If the power supply 204 only includes AC power, then the controller 201 only controls the supply of AC power to the first capacitor C1, the second capacitor C2, and the third capacitor C3, so that the resonant control circuit can generate... Figure 3 The voltage waveforms U1, U2, and U3 are shown. Figure 3 It is known that the input signals received by the controller 201 are different within different preset durations. The controller 201 controls the conduction of different AC voltage switches according to the parameters of the working frequency band read from the input signal, and transmits voltages of different frequencies and amplitudes through the first capacitor C1, the second capacitor C2 or the third capacitor C3 to the first inductor L1 or the second inductor L2 working in the corresponding preset working frequency band, so that the corresponding heating resistor R1 or R2 resonates and resonates to heat the e-liquid.

[0073] If the power supply 204 only includes a DC power supply, the controller 201 only controls the DC power supply U4 to be directly supplied to the heating resistors R1 and R2 through the first inductor L1 and the second inductor L2. When there is only a DC power supply U4, the first inductor L1 and the second inductor L2 can be regarded as wires that can carry DC current.

[0074] If the power supply 204 includes both AC power and DC power, the controller 201 can control the supply of AC power to the first capacitor C1, the second capacitor C2 and the third capacitor C3 at the same time, before or after, and also control the supply of DC power directly to the heating resistors R1 and R2 through the first inductor L1 and the second inductor L2.

[0075] Please see Figure 4 , Figure 4 This is a voltage waveform diagram of another resonant control circuit in an embodiment of this application. Figure 4As can be seen from the voltage waveform, the power supply in the resonant control circuit includes both AC and DC power, and the resonant control circuit continuously provides DC voltage U4 while providing AC voltage. Thus, during the first preset time period, the first voltage U1 of the heating resistor R1 connected to the first inductor L1 will be superimposed with the DC voltage U4, increasing the power of the heating resistor R1 in resonant heating the e-liquid. Similarly, during the second preset time period, the second voltage U2 of the heating resistor R2 connected to the second inductor L2 will be superimposed with the DC voltage U4, increasing the power of the heating resistor R2 in resonant heating the e-liquid. During the third preset time period, the third voltage U3 applied to both the heating resistor R1 connected to the first inductor L1 and the heating resistor R2 connected to the second inductor L2 will be superimposed with the DC voltage U4, thus simultaneously increasing the power of the heating resistors R1 and R2 in resonant heating the e-liquid.

[0076] In the resonant control circuit of this application embodiment, the controller can control the capacitors and inductors operating in the same frequency band to resonate according to different input signals within different preset durations. This allows each heating resistor to resonate and heat the e-liquid under different voltage and power conditions, thereby producing different flavors in the heated or atomized e-liquid to meet the experience needs of different users. Furthermore, the controller allows each heating resistor to work alternately within different preset durations, thus reducing the workload of the heating resistors and further improving the performance of the heating resistors and the electronic atomizing device equipped with them, extending the service life of the heating resistors and the electronic atomizing device. In addition, due to the resonant vibration, the local carbon deposits on the heating resistors can be shaken off and peeled off by the vibration, reducing local carbon deposits on the heating resistors and improving the flavor of the atomized e-liquid vapor.

[0077] Second circuit structure embodiment: In this embodiment, as an example, it is assumed that the working substance is tobacco paste. When the number of inductors L is less than the number of heating resistors R, the heating resistors may include a first heating resistor and a second heating resistor. At least one end of the first heating resistor is connected to one end of at least one inductor L, and one end of the at least one second heating resistor and the other end of the inductor L are connected to the first node A. The other ends of the at least one first heating resistor and the at least one second heating resistor are both connected to the power supply. The operating frequency bands of each inductor L are different.

[0078] The other circuit structures in this embodiment are the same as those described above. Figure 2 The circuit structure of the resonant control circuit in the Chinese embodiment is similar, and will not be described in detail here.

[0079] Specifically, please see Figure 5 , Figure 5 This is a circuit connection diagram of another resonant control circuit in an embodiment of this application. Figure 5 As can be seen, the resonant control circuit in this embodiment includes a controller 501, a voltage-inductance resonant module 502, a heating module 503, and a power supply 504.

[0080] In the resonant control circuit of this embodiment, the heating module 503 includes a first heating resistor R1 and a second heating resistor R2. The voltage-inductance resonant module 502 includes an inductor, namely the first inductor L1, and two capacitors C, namely the first capacitor C1 and the second capacitor C2. The AC voltage switch includes a first AC voltage switch K1 and a second AC voltage switch K2. One end of the first heating resistor R1 is connected to one end of the first inductor L1, and one end of the second heating resistor R2 and the other end of the first inductor L1 are connected to the first node A.

[0081] When the first AC voltage switch K1 is turned on and the second AC voltage switch K2 is turned off, the first capacitor C1 and the first inductor L1 are configured to resonate within a first preset operating frequency band. This causes the first heating resistor R1, connected to the first inductor L1, to resonantly heat the tobacco paste through the applied first AC voltage U1. Simultaneously, the first capacitor C1 directly transmits the first AC voltage U1 from the AC power supply to the second heating resistor R2, allowing the second heating resistor R2 to heat the tobacco paste without resonance. In other words, the first heating resistor R1 and the second heating resistor R2 operate simultaneously at this time.

[0082] With the second AC voltage switch K2 turned on and the first AC voltage switch K1 turned off, the second capacitor C2 is configured to transmit the second AC voltage U2 from the AC power supply to the second heating resistor R2, so that the second heating resistor R2 heats the tobacco paste without resonance. Simultaneously, since the operating frequency band of the first inductor L1 is different from that of the second capacitor C2, the first inductor L1 will not resonate with the second capacitor C2, and therefore the first heating resistor R1 will not operate. In other words, only the second heating resistor R2 is working at this time.

[0083] In other words, in this embodiment, the resonant control circuit transmits AC voltage to the second heating resistor R2 regardless of which AC voltage switch is turned on. The second heating resistor R2 continuously heats the e-liquid without resonance. Therefore, the second heating resistor can be regarded as the main heating resistor in the resonant control circuit or the main heating wire in the electronic atomizing device. As long as there is current, it can work continuously. The first heating resistor R1 only resonates and heats when the first AC voltage switch K1 is turned on. Therefore, the first heating resistor R1 can be regarded as the auxiliary heating resistor or the auxiliary heating wire in the electronic atomizing device.

[0084] Figure 5 In the process, when the DC voltage switch is turned on, since there is no capacitor C, the first inductor L1 is equivalent to part of the wire, directly transmitting the DC voltage to the heating resistor R1, and at the same time, directly transmitting the DC voltage to the heating resistor R2 connected to the first node A. In this way, the heating resistors R1 and R2 can heat the tobacco paste without resonance.

[0085] In this embodiment, please refer to Figure 6 , Figure 6 This is a voltage waveform diagram of the first heating resistor R1 and the second heating resistor R2 applied in another resonant control circuit in this embodiment of the application. Figure 6 In the upper middle figure, the horizontal axis represents time T, and the vertical axis represents the voltage U applied to the first heating resistor R1. In the lower figure, the horizontal axis represents time T, and the vertical axis represents the voltage U applied to the second heating resistor R2.

[0086] If power supply 504 only includes AC power, then controller 501 only controls the supply of AC power to the first capacitor C1 and the second capacitor C2.

[0087] Depend on Figure 6 It is known that within the first preset time period T1, the controller receives the first input signal and reads the parameters of the first preset operating frequency band and the first AC voltage U1 of the first input signal. Then, based on these read parameters, it controls the first AC voltage switch K1 to turn on and the second AC voltage switch K2 to turn off. The first capacitor C1 then transmits the first AC voltage U1 to the first inductor L1 and the second heating resistor R2 respectively. The first inductor L1 resonates with the first capacitor C1 in the first preset operating frequency band and applies the first AC voltage U1 to the first heating resistor R1, causing the first heating resistor R1 to resonate and heat the tobacco paste. At the same time, the second heating resistor R2 undergoes non-resonant heating due to the application of the first AC voltage U1.

[0088] During the second preset time period T2, the controller receives the second input signal and reads its operating frequency band and voltage parameters. Based on these parameters, it controls the second AC voltage switch K1 to turn on, while the first AC voltage switch K1 turns off. The second capacitor C2 then directly transmits the second AC voltage U2 to the second heating resistor R2, causing non-resonant heating of R2. Simultaneously, the first inductor L1 does not resonate because its operating frequency band differs from that of the second capacitor C1. Therefore, no voltage is applied to the first heating resistor R1, meaning its resistance is zero, and R1 does not heat up.

[0089] If the power supply only includes DC power, the controller 501 controls the DC power switch to turn on, providing DC power U4 to the first inductor L1 and the second heating resistor R2 respectively. The first inductor L1 can be regarded as a wire to allow the DC voltage U4 to pass through.

[0090] If power supply 504 includes both AC and DC power, then controller 501 can simultaneously, before, or after controlling the supply of AC power to the first capacitor C1, the second capacitor C2, and the third capacitor C3, and can also control the supply of DC power to the first heating resistor R1 and the second heating resistor R2. See also... Figure 7 , Figure 7 This is a voltage waveform diagram of another resonant control circuit in an embodiment of this application. Figure 7 In both the upper and lower figures, the horizontal axis represents time T. The vertical axis of the upper figure represents the voltage U applied to the first heating resistor R1, and the vertical axis of the lower figure represents the voltage U applied to the second heating resistor R2.

[0091] Depend on Figure 7 As can be seen from the voltage waveform, the power supply in the resonant control circuit includes both AC and DC power. The resonant control circuit provides a first AC voltage U1 to the first heating resistor R1 and the second heating resistor R2 during the first preset duration T1, and then provides a second AC voltage U2 to the second heating resistor R2 during the second preset duration T2. ​​Following this, it provides a DC voltage U4 to the first heating resistor R1 and the second heating resistor R2 during the fourth preset duration T4. In this case, because the preset durations are different, the DC voltage U4 will not be superimposed on the first AC voltage U1 and the second AC voltage U2.

[0092] The resonant control circuit of the first connection method has been described in detail above. The second connection method will be described in detail below.

[0093] (ii) Circuit connection method in which the heating resistor is connected to the capacitor and the inductor is connected to the AC voltage switch; In this embodiment, this connection method can be further divided into two different circuit structure embodiments. The first circuit structure embodiment can be a circuit structure in which the number of heating resistors R and the number of capacitors C are the same. The second circuit structure embodiment can be a circuit structure in which the number of capacitors C is less than the number of heating resistors R. The following describes these two specific circuit structures in detail.

[0094] First circuit structure embodiment: In this embodiment, when the number of heating resistors R and the number of capacitors C in the resonant control circuit are the same, one end of each heating resistor R is connected to one end of a capacitor C, the other end of each heating resistor R is connected to a power supply, and the other end of each capacitor C is connected to the first node A. The operating frequency bands of each capacitor C are different.

[0095] The first node A is connected to one end of at least two inductors L, and the other end of at least two inductors L is connected to one end of their respective AC voltage switches K. The number of AC voltage switches K is the same as the number of inductors L.

[0096] It should be noted that, in this embodiment, medical drugs are used as examples to illustrate the working substance. For example, medical drugs can be liquid, solid, or semi-solid drugs for treating sore throat or tracheitis.

[0097] In this embodiment, Figure 8 The power supply 804 shown may include an AC power supply for providing power to cause the inductor L and the corresponding capacitor C to resonate in the corresponding operating frequency band.

[0098] Specifically, Figure 8 The resonant control circuit shown may include only a first AC voltage switch K1, a second AC voltage switch K2, and a third AC voltage switch K3. The controller 801 determines which AC voltage switch to activate based on different received input signals, causing a group of inductors L and capacitors C connected to the activated AC voltage switch to resonate within a corresponding preset operating frequency band. This causes the heating resistor R in the group to resonate and heat the medical drug. Since the input signals and the corresponding preset operating frequency bands are different, the resulting resonances are also different. The amount of drug atomized by the resonant heating is also different per unit time, or the medical drug may produce different medicinal properties at different temperatures after heating, thereby meeting the treatment needs of a wide range of patients.

[0099] The other end of the AC voltage switch K is connected to the power supply and the controller respectively. The capacitor C resonates with the inductor L, which operates in the corresponding operating frequency band, according to the operating frequency band selected by the controller, so that the corresponding heating resistor R resonates and heats the medical drug.

[0100] In this embodiment, the resonant control circuit includes at least two heating resistors, at least two capacitors C, and at least three inductors L.

[0101] Specifically, please see Figure 8 , Figure 8 This is a circuit connection diagram of another resonant control circuit in an embodiment of this application. Figure 8It can be seen that the resonant control circuit includes a controller 801, a voltage-inductance resonant module 802, a heating module 803, and a power supply 804.

[0102] In this embodiment, the number of heating resistors R and the number of capacitors C in the resonant control circuit are the same, such as Figure 8 As shown, the inductor L in the voltage-inductance resonant module 802 may include a first inductor L1, a second inductor L2, and a third inductor L3; the AC voltage switch may include a first AC voltage switch K1, a second AC voltage switch K2, and a third AC voltage switch K3; the capacitor C may include a first capacitor C1 and a second capacitor C2; and the heating resistors in the heating module 803 are R3 and R4, respectively. One end of the first capacitor C1 and one end of the second capacitor C2 are respectively connected to one of the heating resistors R3 and R4, and the other end of the first capacitor C1 and the other end of the second capacitor C2 are respectively connected to the first node A.

[0103] It should be noted that in this embodiment, since the first capacitor C1 and the second capacitor C2 connected to the heating resistors R3 and R4 have the characteristic of passing AC and blocking DC, the power supply 804 may not include a DC power supply.

[0104] In this embodiment, the controller can control the on and off of the first AC voltage switch K1, the second AC voltage switch K2, and the third AC voltage switch K3 according to the received input signal, thereby controlling each heating resistor to resonate and heat the medical drug at different operating frequencies. This allows the heated or atomized medical drug to produce different medicinal properties or contain different amounts of medical drug per unit time, meeting the treatment needs of a wide range of patients. Moreover, it allows each heating resistor to work alternately for different preset durations, rather than continuously, thus reducing the workload of the heating resistors and improving the performance of the heating resistors and the electronic atomizing device equipped with them, extending their service life. In addition, the resonant vibration can also cause local carbon deposits attached to the heating resistors R3 and R4 to fall off, reducing local carbon deposits on the heating resistors and thus reducing carbon impurities discharged with the atomized medical drug, improving the purity of the atomized medical drug, enhancing its efficacy, and further extending the service life of the heating resistors R3 and R4 and the electronic atomizing device equipped with them. With the first AC voltage switch K1 turned on and the second AC voltage switch K2 and the third AC voltage switch K3 turned off, the first inductor L1 and the first capacitor C1 are configured to resonate within a first preset operating frequency band, causing the heating resistor R3 connected to the first capacitor C1 to resonate and heat the medical drug. Simultaneously, since the operating frequency band of the second capacitor C2 is different from that of the first inductor L1, the second capacitor C2 will not resonate with the first inductor L1, and therefore, the second capacitor C2 is not working. Consequently, the heating resistor R4 connected to the second capacitor C2 will not resonate and heat the herbal extract.

[0105] With the second AC voltage switch K2 turned on and the first AC voltage switch K1 and the third AC voltage switch K3 turned off, the second inductor L2 and the second capacitor C2 are configured to resonate in a second preset operating frequency band, causing the heating resistor R4 connected to the second inductor L2 to resonate and heat the medical drug. Simultaneously, since the operating frequency band of the first capacitor C1 is different from that of the second inductor L2, the first capacitor C1 will not resonate with the second inductor L2, and therefore, the first capacitor C1 is not working. Consequently, the heating resistor R3 connected to the first capacitor C1 will not resonate and heat the herbal extract.

[0106] When the third AC voltage switch K3 is turned on and the first AC voltage switch K1 and the second AC voltage switch K2 are both turned off, the third inductor L3, the first capacitor C1 and the second capacitor C2 are configured to resonate together in the third preset operating frequency band, so that the heating resistors R3 and R4 resonate to heat the medical drug.

[0107] It should be noted that the third preset operating frequency band is the frequency band that overlaps with the first preset operating frequency band and the second preset operating frequency band.

[0108] In this embodiment, please refer to Figure 9 , Figure 9 This is a voltage waveform generated by a resonant control circuit in one of the embodiments of this application. Figure 9 In both the upper and lower graphs, the horizontal axis represents time T, and the vertical axis of the upper graph represents the voltage U across the heating resistor R3. R3 The vertical axis of the graph below represents the voltage U across the heating resistor R4. R4 If power supply 804 only includes AC power, then controller 801 only controls the supply of AC power to the first inductor L1, the second inductor L2, and the third inductor L3, so that the resonant control circuit can generate... Figure 9 The voltage waveforms U1, U2, and U3 of the heating resistors R3 and R4 during different preset time periods are shown. Figure 8 It is known that the input signals received by the controller 801 are different within different preset durations. The controller 801 controls the conduction of different AC voltage switches according to the parameters of the working frequency band read from the input signal, and transmits voltages of different frequencies and amplitudes through the first inductor L1, the second inductor L2 or the third inductor L3 to the first capacitor C1 or the second capacitor C2 that works in the corresponding preset working frequency band, so that the corresponding heating resistor R3 or R4 resonates and resonantly heats the medical drug.

[0109] Second circuit structure embodiment: In this embodiment, as an example, it is assumed that herbal plant extracts are used as the working substance, such as herbal aromatherapy for relieving human nerve fatigue, or herbal plants for medical and non-medical purposes to enhance the excitation of the human central nervous system.

[0110] When the number of capacitors C is less than the number of heating resistors R, the heating resistors may include a third heating resistor and a fourth heating resistor. At least one end of the third heating resistor is connected to one end of at least one capacitor C. One end of the at least one fourth heating resistor and the other end of the capacitor C are connected to the first node A. The other ends of the at least one third heating resistor and the at least one fourth heating resistor are connected to the power supply. The operating frequency bands of each capacitor C are different.

[0111] The first node A is connected to one end of at least two inductors L, and the other end of at least two inductors L is connected to one end of their respective AC voltage switches K. The number of AC voltage switches K is the same as the number of inductors L.

[0112] In this embodiment, the resonant control circuit includes at least two heating resistors, at least one capacitor C, and at least two inductors L.

[0113] Specifically, please see Figure 10 , Figure 10 This is a circuit connection diagram of another resonant control circuit in an embodiment of this application. Figure 10 As can be seen, the resonant control circuit in this embodiment includes a controller 1001, a voltage-inductance resonant module 1002, a heating module 1003, and a power supply 1004.

[0114] In the resonant control circuit of this embodiment, when the number of capacitors C is less than the number of heating resistors R, such as Figure 10 As shown, the inductor L in the voltage-inductance resonant module 1002 may include a first inductor L1 and a second inductor L2, the AC voltage switch K may include a first AC voltage switch K1 and a second AC voltage switch K2, the capacitor C may include a first capacitor C1, and the heating resistor R in the heating module 1003 may include a third heating resistor R3 and a fourth heating resistor R4, wherein one end of the third heating resistor R3 is connected to one end of the first capacitor C1, and one end of the fourth heating resistor R4 and the other end of the first capacitor C1 are respectively connected to the first node A.

[0115] With the first AC voltage switch K1 turned on and the second AC voltage switch K2 turned off, the first inductor L1 and the first capacitor C1 are configured to resonate within a first preset operating frequency band. This causes the third heating resistor R3, connected to the first capacitor C1, to resonate and heat the herbal extract. Simultaneously, the first inductor L1 directly transmits the AC voltage U1 from the AC power supply to the fourth heating resistor R4, allowing the fourth heating resistor R4 to heat the herbal extract without resonance. In other words, the third heating resistor R3 and the fourth heating resistor R4 operate simultaneously.

[0116] When the second AC voltage switch K2 is turned on and the first AC voltage switch K1 is turned off, the second inductor L2 is configured to transmit the second AC voltage U2 of the AC power supply to the fourth heating resistor R4, so that the fourth heating resistor R4 performs non-resonant heating of the herbal plant extract. At the same time, since the operating frequency band of the first capacitor C1 is different from that of the second inductor L2, the first capacitor C1 does not work and will not transmit the second AC voltage U2 to the third heating resistor R3. Therefore, the third heating resistor R3 does not work.

[0117] In other words, in this embodiment, the resonant control circuit transmits AC voltage to the fourth heating resistor R4 regardless of which AC voltage switch is turned on. The fourth heating resistor R4 continuously heats the herbal extract without resonance. Therefore, the fourth heating resistor can be regarded as the main heating resistor in the resonant control circuit or the main heating wire in the electronic atomization device. As long as there is current, it can work continuously. The third heating resistor R3 only resonates and heats when the first AC voltage switch K1 is turned on. Therefore, the third heating resistor R3 can be regarded as the auxiliary heating resistor or the auxiliary heating wire in the electronic atomization device.

[0118] Figure 10 In this embodiment, when the DC voltage switch is turned on, only the fourth heating resistor R4 can heat the herbal extract without resonance. In this embodiment, the power supply 1004 may also include a DC power supply, which is used to provide a DC voltage U4 to the fourth heating resistor R4, so that the fourth heating resistor R4 can heat the herbal extract without resonance.

[0119] The first node A is connected to one end of at least one DC voltage switch K4, and the other end of the DC voltage switch K4 is connected to the DC power supply 1004 and the controller 1001 respectively.

[0120] When the DC voltage switch K4 is turned on, and when the number of capacitors C is less than the number of heating resistors R, the DC voltage U4 of the DC power supply is transmitted to the fourth heating resistor R4, so that the fourth heating resistor R4 heats the herbal plant extract without resonance. At the same time, the third heating resistor R3 is connected to the first capacitor C1. Due to the characteristic that the capacitor passes AC and blocks DC, the third heating resistor R3 will not perform non-resonant heating and will not work.

[0121] In this embodiment, please refer to Figure 11 , Figure 11 This is a timing diagram of the voltage waveforms applied to the third heating resistor R3 and the fourth heating resistor R4 in another resonant control circuit in this embodiment of the application. Figure 11 In the upper middle figure, the horizontal axis represents time T, and the vertical axis represents the voltage U applied to the third heating resistor R3. In the lower figure, the horizontal axis represents time T, and the vertical axis represents the voltage U applied to the fourth heating resistor R4.

[0122] If the power supply 1004 only includes AC power, then the controller 1001 only controls the supply of AC power to the first inductor L1 and the second inductor L2.

[0123] Depend on Figure 11It is known that within the first preset time period T1, the controller receives the first input signal and reads the parameters of the first preset operating frequency band and the first AC voltage U1 of the first input signal. Then, based on these read parameters, it controls the first AC voltage switch K1 to turn on and the second AC voltage switch K2 to turn off. The first inductor L1 then transmits the first AC voltage U1 to the first capacitor C1 and the fourth heating resistor R4 respectively. The first capacitor C1 resonates with the first inductor L1 in the first preset operating frequency band and applies the first AC voltage U1 to the third heating resistor R3, causing the third heating resistor R3 to resonate and heat the tobacco paste. At the same time, the fourth heating resistor R4 undergoes non-resonant heating due to the application of the first AC voltage U1.

[0124] During the second preset time period T2, the controller receives the second input signal and reads its operating frequency band and voltage parameters. Based on these parameters, it controls the second AC voltage switch K1 to turn on, while the first AC voltage switch K1 turns off. The second inductor L2 then directly transmits the second AC voltage U2 to the fourth heating resistor R4. The fourth heating resistor R4 then undergoes non-resonant heating due to the applied second AC voltage U2. Simultaneously, the first capacitor C1 does not resonate because its operating frequency band differs from that of the second inductor L1. Therefore, no voltage is applied to the third heating resistor R3, meaning its resistance is zero, and R3 does not heat up.

[0125] If the power supply only includes DC power, the controller 1001 controls the DC power switch to turn on, providing DC power U4 to the fourth heating resistor R4.

[0126] If the power supply 1004 includes both AC and DC power, then the controller 1001 can simultaneously, before, or after controlling the supply of AC power to the first inductor L1, the second inductor L2, and the third inductor L3, also control the supply of DC power to the third heating resistor R3 and the fourth heating resistor R4. Please refer to [link to relevant documentation]. Figure 12 , Figure 12 This is a voltage waveform diagram of another resonant control circuit in an embodiment of this application. Figure 12 In both the upper and lower figures, the horizontal axis represents time T. The vertical axis of the upper figure represents the voltage U applied to the third heating resistor R3, and the vertical axis of the lower figure represents the voltage U applied to the fourth heating resistor R4.

[0127] Depend on Figure 12As can be seen from the voltage waveform, the power supply in the resonant control circuit includes both AC and DC power. The resonant control circuit provides a first AC voltage U1 to the third heating resistor R3 and the fourth heating resistor R4 during the first preset duration T1, and a second AC voltage U2 to the fourth heating resistor R4 during the second preset duration T2. ​​At the same time, a DC voltage U4 is also provided to the fourth heating resistor R4 during the fourth preset duration T4. In this embodiment, the fourth preset duration T4 coincides with the second preset duration T2. ​​Due to the characteristic of the capacitor to pass AC and block DC, no DC voltage U4 is applied to the third heating resistor R3.

[0128] It should be noted that, Figure 12 The amplitude of the DC voltage U4 shown is the portion of the amplitude of the second AC voltage U2 (marked on the vertical axis) to the DC voltage U4. In this case, as... Figure 12 As shown, during the second preset duration, the DC voltage U4 will be superimposed on the second AC voltage U2.

[0129] In this embodiment, since a power supply voltage can be continuously transmitted to the fourth heating resistor R4 during the power-on process, while the third heating resistor can only work when the first AC voltage switch K1 is turned on, the two heating resistors work as a main and secondary heating mode to provide a continuous and ever-changing heating voltage for the working substance. In this way, the user can select different heating methods according to actual needs to obtain the required heated or atomized working substance.

The description of the resonant control circuit above already includes extensive explanations of the technical content of the resonant control method based on the aforementioned resonant control circuit. For a more complete explanation and supplement to the technical content, please refer to the following content to understand the technical solution of the resonant control method in the embodiments of this application.

[0132] The resonance control method used in the embodiments of this application uses a resonance control circuit such as... Figure 1 As shown, the resonant control method may include the following within the total preset time: The controller 101 selects different operating frequency bands according to different input signals to control the capacitor-inductor resonant module 102 to generate different resonances. The capacitor-inductor resonant module 102 includes at least one capacitor C and at least one inductor L, and the heating module 103 includes at least two heating resistors R. Power supply 104 provides power voltage to controller 101 and capacitor-inductor resonant module 102; The heating module 103 resonates and heats the working substance according to the different resonances generated by the capacitor-inductor resonant module 102.

[0133] In the resonance control method of this application embodiment, the controller of the resonance control circuit selects different operating frequency bands according to different input signals to control the capacitor-inductor resonant module to generate different resonances. This allows the heating module to perform different resonant heating on the working material according to different resonances. This enables the working material to undergo different heating or atomization under different conditions, resulting in diverse forms of the heated working material and providing users with more choices. Furthermore, since the heating module is not constantly in a heated state, or not in the same heated state, it reduces the generation of localized carbon deposits on the heating module, thereby extending its lifespan. In addition, it reduces the amount of impurities introduced into the working material due to localized carbon deposits, improving the user experience.

[0134] The following description, with reference to the foregoing, explains the resonance control methods associated with various circuit connection methods in the specific embodiments.

[0135] The first method: The heating resistors R and the inductors L are connected together, and the number of heating resistors R is the same as the number of inductors L. Please see Figure 3 , Figure 3 For based on Figure 2 The voltage waveform diagram of the resonance control method of the resonance control circuit shown can also be called a voltage timing diagram. When the power supply is AC, the resonance control method of the resonance control circuit in this embodiment is as follows: Within a first preset duration T1, the controller 201 controls the first AC voltage switch K1 to turn on according to the first input signal, and the second AC voltage switch K2 and the third AC voltage switch K3 are both turned off. The first capacitor C1 and the first inductor L1 are configured to resonate through the first AC voltage U1 in the first preset operating frequency band, so that the heating resistor R1 connected to the first inductor L1 resonates and heats the working substance. The first input signal contains the parameter set of the first AC voltage U1.

[0136] Within the second preset time period T2, the controller 201 controls the second AC voltage switch K2 to turn on according to the second input signal, and the first AC voltage switch K1 and the third AC voltage switch K3 are both turned off. The second capacitor C2 and the second inductor L2 are configured to resonate through the second AC voltage U2 in the second preset operating frequency band, so that the heating resistor R2 connected to the second inductor L2 resonates and heats the working substance. The second input signal contains the parameter set of the second AC voltage.

[0137] Within the third preset duration T3, the controller 201 controls the third AC voltage switch K3 to turn on according to the third input signal, while the first AC voltage switch K1 and the second AC voltage switch K2 are both turned off. The third capacitor C3, the first inductor L1, and the second inductor L2 are configured to resonate together through the third AC voltage U3 in the third preset operating frequency band, so that the two heating resistors R1 and R2 resonate and heat the working substance together. The third input signal contains the parameter set of the third AC voltage U3. The third preset operating frequency band is the frequency band that overlaps with the first preset operating frequency band and the second preset operating frequency band.

[0138] It should be noted that the total preset duration T may include the first preset duration T1, the second preset duration T2, and the third preset duration T3.

[0139] Furthermore, this circuit connection method and resonance control method, since the two heating resistors R1 and R2 can alternately resonate and heat the working substance, can be understood as a case where the heating resistors do not distinguish between main and auxiliary heating wires.

[0140] In this embodiment, it can be Figure 3 The voltage waveform of the heating resistors shown can be further broken down into the voltage waveforms of heating resistors R1 and R2 respectively. Please refer to [link / reference]. Figure 13 , Figure 13 Examples of embodiments in this application Figure 3 The diagram shows a breakdown of the voltage waveform of the heating resistor. (See attached image.) Figure 13 As shown, Figure 13 The diagram shows the voltage waveforms of heating resistors R1 and R2, which can also be called voltage timing diagrams.

[0141] Furthermore, when the power supply also includes a DC power supply, please refer to [link to relevant documentation]. Figure 14 , Figure 14 for Figure 4 The voltage waveform of the heating resistor is shown in the exploded view.

[0142] The resonance control method in this application embodiment is as follows: Within the fourth preset time period T4, the controller 201 controls the DC voltage switch K4 to turn on according to the fourth input signal. The first inductor L1 and the second inductor L2 respectively transmit the DC voltage U4 of the DC power supply to the heating resistors R1 and R2, so that the heating resistors R1 and R2 simultaneously perform non-resonant heating on the working substance.

[0143] It should be noted that the total preset duration T may also include a fourth preset duration T4, which does not overlap, partially overlaps or completely overlaps with any one or more of the preset durations of the first preset duration T1, the second preset duration T2 and the third preset duration T3.

[0144] In this embodiment, the fourth preset duration T4 is the sum of the first preset duration T1, the second preset duration T2, and the third preset duration T3. That is to say, the resonant control circuit provides AC power while simultaneously providing DC power.

[0145] The second method involves connecting heating resistors R and inductors L, with the number of inductors L being less than the number of heating resistors R. Please see Figure 6 , Figure 6 For based on Figure 5 The voltage waveform diagram of the resonance control method of the resonance control circuit shown can also be called a voltage timing diagram. When the power supply is AC, the resonance control method of the resonance control circuit in this embodiment is as follows: Within a first preset duration T1, the controller 501 controls the first AC voltage switch K1 to turn on and the second AC voltage switch K1 to turn off according to the first input signal U1. The first capacitor C1 and the first inductor L1 are configured to resonate through the first AC voltage U1 in the first preset operating frequency band, so that the first heating resistor R1 connected to the first inductor L1 resonates and heats the working material. At the same time, the first capacitor C1 transmits the first AC voltage to the second heating resistor R2 so that the second heating resistor R2 heats the working material without resonance. The first input signal contains the parameter set of the first AC voltage U1.

[0146] Within the second preset time period T2, the controller 501 controls the second AC voltage switch K2 to turn on and the first AC voltage switch K1 to turn off according to the second input signal. The second capacitor C2 is configured to transmit the second AC voltage U2 to the second heating resistor R2 so that the second heating resistor R2 performs non-resonant heating on the working substance, while the first heating resistor R1 does not work.

[0147] It should be noted that the total preset duration T may include the first preset duration T1 and the second preset duration T2.

[0148] Furthermore, when the power supply also includes a DC power supply, please refer to [link to relevant documentation]. Figure 7 The resonance control method in this application embodiment is as follows: Within the fourth preset time period T4, the controller controls the DC voltage switch K4 to turn on according to the fourth input signal, and the inductor L transmits the DC voltage U4 of the DC power supply to the heating resistors R1 and R2, so that the first heating resistor R1 and the second heating resistor R2 perform non-resonant heating on the working substance.

[0149] In this embodiment, the fourth preset duration T4 is after the second preset duration T2, so it does not overlap with the first preset duration T1 and the second preset duration T2. ​​Therefore, the DC voltage U4 applied to the first heating resistor R1 and the second heating resistor R2 during the fourth preset duration T2 will not overlap with the first AC voltage U1 and the second AC voltage U2.

[0150] The circuit connection method and resonance control method in this embodiment can be understood as a case where the heating resistor does not distinguish between main and auxiliary heating wires.

[0151] The third method: The heating resistor R is connected to the capacitor C, and the number of heating resistors R is the same as the number of capacitors C. Please see Figure 9 , Figure 9 For based on Figure 8 The voltage waveform diagram of the resonance control method of the resonance control circuit shown can also be called a voltage timing diagram. When the power supply is AC, the resonance control method of the resonance control circuit in this embodiment is as follows: Within a first preset duration T1, the controller 801 controls the first AC voltage switch K1 to turn on according to the first input signal, and the second AC voltage switch K2 and the third AC voltage switch K3 are both turned off. The first inductor L1 and the first capacitor C1 are configured to resonate through the first AC voltage U1 in the first preset operating frequency band, so that the heating resistor R3 connected to the first capacitor resonates and heats the working substance. The first input signal contains the parameter set of the first AC voltage U1.

[0152] Within the second preset time period T2, the controller 801 controls the second AC voltage switch K2 to turn on according to the second input signal. When the first AC voltage switch K1 and the third AC voltage switch K3 are both off, the second inductor L2 and the second capacitor C2 are configured to resonate through the second AC voltage U2 in the second preset operating frequency band, so that the heating resistor R4 connected to the second inductor L2 resonates and heats the working substance. The second input signal contains the parameter set of the second AC voltage U2.

[0153] Within the third preset duration T3, the controller 801 controls the third AC voltage switch K3 to turn on according to the third input signal. When the first AC voltage switch K1 and the second AC voltage switch K2 are both off, the third inductor L3, the first capacitor C1 and the second capacitor C2 are configured to resonate together through the third AC voltage U3 in the third preset operating frequency band, so that the two heating resistors R3 and R4 resonate and heat the working substance together. The third input signal contains the parameter set of the third AC voltage. The third preset operating frequency band is the frequency band that overlaps with the first preset operating frequency band and the second preset operating frequency band.

[0154] It should be noted that the total preset duration T may include the first preset duration T1, the second preset duration T2, and the third preset duration T3.

[0155] In this embodiment Figure 8 The resonant control circuit shown does not require an additional DC power supply in its circuit design because the capacitor cannot operate with a DC voltage.

[0156] In this embodiment, the circuit connection method and resonance control method can be understood as a case where the heating resistors do not distinguish between main and auxiliary heating wires, since the two heating resistors R3 and R4 can alternately resonate and heat the working substance.

[0157] In the resonant heating method of this embodiment, the controller can control the conduction and disconnection of each AC voltage switch according to the received input signal, thereby controlling each heating resistor to resonate and heat the working substance in different operating frequency bands. This can meet the different needs of a wide range of users. Moreover, since each heating resistor can work alternately within a few different preset durations, the workload of the heating resistor is reduced, the performance of the heating resistor and the electronic atomizing device equipped with the heating resistor is improved, and the service life is extended. Furthermore, the resonant vibration can cause the local carbon deposits attached to the heating resistor to fall off, reducing impurities in the atomized working substance, improving the purity of the atomized working substance, and further extending the service life of the heating resistor and the electronic atomizing device.

[0158] The fourth type: The heating resistor R is connected to the capacitor C, and the number of capacitors C is less than the number of heating resistors R. Please see Figure 11 , Figure 11 For based on Figure 10 The voltage waveform diagram of the resonance control method of the resonance control circuit shown can also be called a voltage timing diagram. When the power supply is AC, the resonance control method of the resonance control circuit in this embodiment is as follows: Within the first preset duration T1, the controller 1001 controls the first AC voltage switch K1 to turn on and the second AC voltage switch K2 to turn off according to the first input signal U1. The first inductor L1 and the first capacitor C1 are configured to resonate through the first AC voltage U1 in the first preset operating frequency band, so that the third heating resistor R3 connected to the first capacitor C1 resonates and heats the working material, while the fourth heating resistor R4 heats the working material without resonance.

[0159] Within the second preset time period T2, the controller 1001 controls the second AC voltage switch K2 to turn on and the first AC voltage switch K1 to turn off according to the second input signal. The second inductor L2 is configured to transmit the second AC voltage U2 to the fourth heating resistor so that the fourth heating resistor R4 can perform non-resonant heating of the working substance. At the same time, since the operating frequency band of the second inductor L2 is different from the operating frequency band of the first capacitor C1, no second AC voltage U2 is transmitted to the third heating resistor R3, and the third heating resistor R3 does not work.

[0160] It should be noted that the total preset duration T may include the first preset duration T1 and the second preset duration T2.

[0161] In this embodiment, since the fourth heating resistor R4 is always performing non-resonant heating whether it is within the first preset time T1 or the second preset time T2, it can be understood that the fourth heating resistor R4 is the main heating wire and the third heating resistor R3 is the auxiliary heating wire.

[0162] Furthermore, when the power supply also includes a DC power supply, please refer to [link to relevant documentation]. Figure 12 The resonance control method in this application embodiment is as follows: Within the fourth preset duration T4, when the controller 1001 controls the DC voltage switch K4 to be turned on according to the fourth input signal, the DC voltage U4 of the DC power supply is transmitted to the fourth heating resistor R4 so that the fourth heating resistor R4 performs non-resonant heating on the working substance. At the same time, since the first capacitor C1 cannot transmit the DC voltage U4 to the third heating resistor R3, the third heating resistor R3 does not work. The fourth preset duration T4 does not coincide with, partially coincides with, or completely coincides with any one or more of the first preset duration T1 and the second preset duration T2.

[0163] It should be noted that, by Figure 12 As can be seen, the fourth preset duration T4 in this embodiment coincides exactly with the second preset duration T2. ​​Therefore, the second AC voltage U2 transmitted to the fourth heating resistor R4 within the second preset duration T2 (that is, the fourth preset duration T4) will be superimposed with the DC voltage U4, thereby increasing the heating power of the fourth heating resistor R4.

[0164] In the resonance control method of this embodiment, since a power supply voltage can always be transmitted to the fourth heating resistor R4 during the power-on process, while the third heating resistor R3 can only work when the first AC voltage switch K1 is turned on, the two heating resistors, as a primary and secondary heating mode, provide a continuous and ever-changing heating voltage for the working substance. In this way, the user can select different heating methods according to actual needs to obtain the required heated or atomized working substance.

The embodiments of this application also provide an electronic atomizing device, which includes the aforementioned... Figures 1 to 14 All the technical details of the resonant control circuit and resonant control method shown are not elaborated here.

[0166] The electronic atomizing device in this embodiment, through the circuit structure of the aforementioned resonant control circuit and the working principle of the resonant control method including the resonant control circuit, enables the working substance to be heated or atomized under different conditions. Therefore, the heated working substance can take on various forms to meet the diverse needs of users. Furthermore, since the heating resistor in the heating module is not constantly in a heating state when energized, but works alternately within a certain preset time, it can reduce the generation of local carbon deposits in the heating module, extend the life of the heating module, and improve the purity of the heated or atomized working substance, thereby improving the performance of the working substance and the user experience.
