Resonant circuits are used both to generate signals of a particular frequency and to select a particular frequency from a more complex signal, and are widely used in frequency selection.

Wherein one end of the first inductor L1 and one end of the second inductor L2 are connected with one corresponding heating resistor R respectively, and the other end of the first inductor L1 and the other end of the second inductor L2 are connected with the first node A respectively.

[0103] In the case that the first alternating voltage switch K1 is turned on and the second alternating voltage switch K2 and the third alternating voltage switch K3 are both turned off, the first capacitor C1 and the first inductor L1 are configured to generate resonance in the first preset working frequency band, so that the heating resistor R1 connected with the first inductor L1 performs resonant heating on the tobacco tar. At the same time, since the working frequency band of the second inductor L2 is different from the working frequency band of the first capacitor C1, the second inductor L2 will not resonate with the first capacitor C1, and thus the second inductor L2 does not work, so that the heating resistor R2 connected with the second inductor L2 will not perform resonant heating on the tobacco tar.

[0104] It should be noted that, as an example, the working substance in the embodiment is tobacco tar.

[0105] ​When the second AC voltage switch K2 is turned on 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 at the second preset working frequency band, so that the heating resistor R2 connected to the second inductor L2 resonantly heats the tobacco tar. At the same time, since the working frequency band of the first inductor L1 is different from the working frequency band of the second capacitor C1, the first inductor L1 does not resonate with the second capacitor C2, and thus the first inductor L1 does not work, so that the heating resistor R1 connected to the first inductor L1 does not resonantly heat the tobacco tar.

[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 capacitor C3, the first inductor L1 and the second inductor L2 are configured to collectively resonate at the third preset working frequency band, so that the heating resistors R1 and R2 collectively resonantly heat the tobacco tar.

[0107] It should be noted that the third preset working frequency band is a frequency band in which the first preset working frequency band and the second preset working frequency band overlap.

[0108] For example, the first preset working frequency band is 40-80 Hz, and the second preset working frequency band is 60-100 Hz, and thus the third preset working 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 working frequency band is in the overlapping part of the first preset working frequency band and the second preset working frequency band, the first inductor L1 and the second inductor L2 can both resonate with the third capacitor C3 at this time, so that the heating resistors R1 and R2 resonantly heat the tobacco tar through the heat generated by the inductive capacitor resonance.

[0109] It should be noted that the power supply in the foregoing embodiments of the present application can include an AC power supply, which is used to provide a power supply for the capacitor C and the inductor L to resonate at the corresponding working frequency band.

[0110] Specifically, Figure 2The resonant control circuit shown can only include the first alternating voltage switch K1, the second alternating voltage switch K2 and the third alternating voltage switch K3, and the controller 201 determines which alternating voltage switch to turn on according to different input signals received, so that a group of capacitors C and inductors L connected with the turned-on alternating voltage switch resonate in the corresponding preset working frequency band, so that the heating resistors R in the group resonate to heat the tobacco tar. Since the input signals and the corresponding preset working frequency bands are different, the resonances generated are also different, and the taste effects of the tobacco tar caused by resonant heating are also different.

[0111] In the embodiment, the capacitors C and the inductors L resonate, which not only enables the heating resistors R1 and R2 to resonate and heat, but also enables the local carbon deposits on the heating resistors R1 and R2 to be shaken off and peeled off due to the vibration of the resonance, thereby reducing the local carbon deposits on the heating resistors R1 and R2, further reducing the carbon impurities discharged together with the atomized tobacco tar vapor, improving the taste of the atomized tobacco tar vapor, and prolonging the service life of the heating resistors R1 and R2 and the electronic atomization device provided with the heating resistors. In addition, since the controller can control the turn-on and turn-off of the first alternating voltage switch K1, the second alternating voltage switch K2 and the third alternating voltage switch K3 according to the input signals received, thereby controlling the heating resistors to resonate and heat the tobacco tar in different working frequency bands, this can enable the heated or atomized tobacco tar to have different tastes, meet the experience needs of different users, and enable the heating resistors to work alternately in part of the preset time period instead of working all the time, thereby reducing the load of the heating resistors, further improving the performance of the heating resistors and the electronic atomization device provided with the heating resistors, and prolonging the service life.

[0112] Further, the power supply in the embodiment of the application can further include a direct current power supply, which is used to provide power to directly energize the heating resistors R1 and R2 and to non-resonantly heat the working substance.

[0113] The first node A is connected with one end of at least one direct current voltage switch K, and the other end of the direct current voltage switch K is connected with the direct current power supply and the controller one by one.

[0114] In the embodiment, specifically, as shown in Figure 2 The first node A is connected with one end of at least one direct current voltage switch K, and the other end of the direct current voltage switch K is connected with the direct current power supply and the controller one by one. Figure 2 The power supply 204 shown can only include an alternating current power supply or a direct current power supply, or both.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] Please see Figure 4 , Figure 4 This is a voltage waveform diagram of another resonant control circuit in an embodiment of this application. Figure 4The voltage waveform can be known that the power supply in the resonance control circuit includes both AC power supply and DC power supply, and the resonance control circuit provides AC voltage and DC voltage U4 at the same time. Thus, when in the first preset time length, the first voltage U1 of the heating resistor R1 connected with the first inductor L1 is superimposed with the DC voltage U4, and the power of the heating resistor R1 for resonant heating of the tobacco tar is increased; similarly, when in the second preset time length, the second voltage U2 of the heating resistor R2 connected with the second inductor L2 is superimposed with the DC voltage U4, and the power of the heating resistor R2 for resonant heating of the tobacco tar is increased; and when in the third preset time length, the third voltage U3 of the heating resistor R1 connected with the first inductor L1 and the heating resistor R2 connected with the second inductor L2 are superimposed with the DC voltage U4, and the power of the heating resistors R1 and R2 for resonant heating of the tobacco tar is increased.

[0120] In the resonance control circuit in the embodiment, the controller can control the capacitors and inductors working in the same working frequency band to generate resonance in different preset time lengths according to different input signals, so that each heating resistor can perform resonant heating of the tobacco tar under different voltages and powers in different conditions, thereby enabling the heated or atomized tobacco tar to have different tastes, meeting the experience needs of different users, and enabling each heating resistor to work alternately in different preset time lengths, thereby reducing the load of the heating resistors, further improving the performance of the heating resistors and the electronic atomization device provided with the heating resistors, and prolonging the service life of the heating resistors and the electronic atomization device. In addition, due to the resonant vibration, the local carbon deposition of the heating resistors can be shaken off and peeled off, the local carbon deposition of the heating resistors is reduced, and the taste of the atomized tobacco tar vapor is improved.

[0121] The second circuit structure embodiment is as follows:

[0122] In the embodiment, as an example, it is assumed that the working substance is tobacco tar. When the number of inductors L is less than the number of heating resistors R, the heating resistors can include first heating resistors and second heating resistors, one end of at least one first heating resistor is connected with one end of at least one inductor L, one end of at least one second heating resistor and the other end of the inductor L are connected with the first node A, the other end of at least one first heating resistor and the other end of at least one second heating resistor are connected with the power supply, and the working frequency bands of the inductors L are different.

[0123] The other circuit structures in the embodiment are similar to the circuit structure of the resonance control circuit in the foregoing Figure 2 embodiment, and details are not described herein again.

[0124] Specifically, please refer toFigure 5 , Figure 5 Figure 2 is a circuit connection diagram of another resonant control circuit in the embodiments of the present application. As can be seen from the figure, the resonant control circuit in the embodiments of the present application comprises a controller 201, a voltage-inductive resonant module 202, a heating module 203 and a power supply 204. Figure 5

[0125] The voltage-inductive resonant module 202 in the resonant control circuit in the embodiments of the present application comprises a first inductor L1 and two capacitors C, i.e. a first capacitor C1 and a second capacitor C2, and the heating module 203 comprises a first heating resistor R1 and a second heating resistor R2.

[0126] In the case where 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 generate resonance in the first preset working frequency band, so that the first heating resistor R1 connected to the first inductor L1 performs resonant heating on the tobacco extract through the applied first AC voltage U1, while the first capacitor C1 directly transmits the first AC voltage U1 of the AC power supply to the second heating resistor R2, so that the second heating resistor R2 performs non-resonant heating on the tobacco extract. In other words, at this time, the first heating resistor R1 and the second heating resistor R2 work simultaneously.

[0127] In the case where the second AC voltage switch K2 is turned on and the first AC voltage switch K1 is turned off, the second capacitor C2 is configured to transmit the second AC voltage U2 of the AC power supply to the second heating resistor R2, so that the second heating resistor R2 performs non-resonant heating on the tobacco extract, while the first inductor L1 does not resonate with the second capacitor C2 because the working frequency band of the first inductor L1 is different from that of the second capacitor C2, and thus the first heating resistor R1 does not work. In other words, at this time, only the second heating resistor R2 works.

[0128] That is, in the resonant control circuit in the embodiments of the present application, the second heating resistor R2 will always perform non-resonant heating on the tobacco extract because the second heating resistor R2 is always transmitted with the AC voltage when either of the AC voltage switches is turned on, and thus the second heating resistor R2 can be regarded as the main heating resistor in the resonant control circuit or the main heating wire in the electronic atomization device, which can always work as long as there is current passing through. The first heating resistor R1 can be regarded as the auxiliary heating resistor or the auxiliary heating wire in the electronic atomization device because the first heating resistor R1 only performs resonant heating when the first AC voltage switch K1 is turned on. ​

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] If the power supply only includes a direct current power supply, the controller 501 controls the direct current power supply switch to be turned on, and provides the direct current power supply U4 to the first inductor L1 and the second heating resistor R2 respectively. The first inductor L1 can only be regarded as a wire to pass the direct current voltage U4.

[0135] If the power supply 504 includes both an alternating current power supply and a direct current power supply, the controller 501 can control the provision of the direct current power supply to the first heating resistor R1 and the second heating resistor R2 at the same time as, or before, or after, the provision of the alternating current power supply to the first capacitor C1, the second capacitor C2 and the third capacitor C3. Please refer to Figure 7 , Figure 7 The voltage waveform diagram of another resonant control circuit in the embodiment. Figure 7 The horizontal axis of the upper, middle and lower graphs is time T, and the vertical axis of the upper graph is the voltage U applied to the first heating resistor R1, and the vertical axis of the lower graph is the voltage U applied to the second heating resistor R2.

[0136] From the voltage waveform of Figure 7 It can be known that the power supply in the resonant control circuit includes both an alternating current power supply and a direct current power supply, and the resonant control circuit provides the first heating resistor R1 and the second heating resistor R2 with the first alternating current voltage U1 for a first preset time T1, and provides the second heating resistor R2 with the second alternating current voltage U2 for a second preset time T2, and then provides the first heating resistor R1 and the second heating resistor R2 with the direct current voltage U4 for a fourth preset time T4. In this case, since the preset times are different, the direct current voltage U4 will not be superimposed with the first alternating current voltage U1 and the second alternating current voltage U2.

[0137] The resonant control circuit of the first connection mode is described in detail above, and the second connection mode is described in detail below.

[0138] (II) The circuit connection mode in which the heating resistor is connected with the capacitor, and the inductor is connected with the alternating current voltage switch;

[0139] In this embodiment, further, this connection mode can also be 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 is the same as the number of capacitors C, and 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 two specific circuit structures are described in detail below.

[0140] The first circuit structure embodiment:

[0141] In the embodiment of the present application, when the number of heating resistors R and the number of inductors L 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 the capacitor C is connected to the first node A. The working frequency bands of the capacitors C are different.

[0142] The first node A is connected to one end of at least two inductors L, and the other end of the at least two inductors L is connected to one end of an alternating voltage switch K. The number of alternating voltage switches K is the same as the number of inductors L.

[0143] It should be noted that the medical drug is taken as the working substance in the embodiment by way of example. The medical drug can be a liquid, solid or semi-solid drug for treating sore throat or tracheal inflammation.

[0144] In the embodiment, Figure 8 The power supply 804 can include an alternating power supply for providing a power supply for the inductor L and the corresponding capacitor C to generate resonance at the corresponding working frequency band.

[0145] Specifically, Figure 8 In the resonance control circuit, only the first alternating voltage switch K1, the second alternating voltage switch K2 and the third alternating voltage switch K3 can be included. The controller 801 determines which alternating voltage switch to turn on according to the different input signals received, so that a group of inductors L and capacitors C connected to the turned-on alternating voltage switch generate resonance at the corresponding preset working frequency band, so that the heating resistors R in the group perform resonance heating on the medical drug. Since the input signals and the corresponding preset working frequency bands are different, the resonance generated is also different. The amount of drug per unit time after the medical drug is atomized by resonance heating is also different, or the medical drug produces different medicinal properties at different temperatures after heating, thereby meeting the treatment needs of a large number of different patients.

[0146] The other end of the alternating voltage switch K is connected to the power supply and the controller. The capacitor C generates resonance with the inductor L working at the corresponding working frequency band selected by the controller, so that the corresponding heating resistor R performs resonance heating on the medical drug.

[0147] In the embodiment, the resonance control circuit includes at least two heating resistors, at least two capacitors C and at least three inductors L.

[0148] Specifically, please refer to Figure 8 , Figure 8 is a circuit connection diagram of another resonance control circuit in the embodiment of the present application. By Figure 8It can be known that the resonance control circuit comprises a controller 801, a voltage inductance resonance module 802, a heating module 803 and a power supply 804.

[0149] In the embodiment, the number of the heating resistors R in the resonance control circuit is the same as the number of the capacitors C, as shown in the figure, the inductor L in the voltage inductance resonance module 802 can comprise a first inductor L1, a second inductor L2 and a third inductor L3, the alternating voltage switch can comprise a first alternating voltage switch K1, a second alternating voltage switch K2 and a third alternating voltage switch K3, the capacitor C can comprise a first capacitor C1 and a second capacitor C2, and the heating resistors in the heating module 803 are R3 and R4 respectively. Wherein, one end of the first capacitor C1 and one end of the second capacitor C2 are connected with one of the heating resistors R3 and R4 respectively, and the other end of the first capacitor C1 and the other end of the second capacitor C2 are connected with the first node A respectively. Figure 8

[0150] It should be noted that, in the embodiment, since the first capacitor C1 and the second capacitor C2 connected with the heating resistors R3 and R4 have the characteristics of passing alternating current and blocking direct current, the power supply 804 can not include a direct current power supply.

[0151] ​In this embodiment, the controller can control the conduction and disconnection of the first alternating voltage switch K1, the second alternating voltage switch K2 and the third alternating voltage switch K3 according to the received input signal, so as to control the resonant heating of the medical drugs by the heating resistors in different working frequency bands. In this way, the heated or atomized medical drugs can have different medicinal properties or contain different amounts of medical drugs per unit time, meeting the treatment needs of different patients. Moreover, the heating resistors can work alternately in part of the preset time period instead of working all the time, thereby reducing the working load of the heating resistors and improving the performance and service life of the heating resistors and the electronic atomization device provided with the heating resistors. In addition, the vibration of the resonance can make the local carbon deposition on the heating resistors R3 and R4 fall off, thereby reducing the local carbon deposition of the heating resistors and the carbon impurities discharged together with the atomized medical drugs, improving the purity of the atomized medical drugs, enhancing the medicinal effect, and further prolonging the service life of the heating resistors R3 and R4 and the electronic atomization device provided with the heating resistors. When the first alternating voltage switch K1 is turned on and the second alternating voltage switch K2 and the third alternating voltage switch K3 are turned off, the first inductor L1 and the first capacitor C1 are configured to resonate at a first preset working frequency band, so that the heating resistor R3 connected to the first capacitor C1 resonantly heats the medical drugs. At the same time, since the working 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 thus the second capacitor C2 does not work. In this way, the heating resistor R4 connected to the second capacitor C2 will not resonantly heat the herbal plant extract.

[0152] When the second alternating voltage switch K2 is turned on and the first alternating voltage switch K1 and the third alternating voltage K3 are turned off, the second inductor L2 and the second capacitor C2 are configured to resonate at a second preset working frequency band, so that the heating resistor R4 connected to the second inductor L2 resonantly heats the medical drugs. At the same time, since the working frequency band of the first capacitor C1 is different from that of the second inductor L1, the first capacitor C1 will not resonate with the second inductor L2, and thus the first capacitor C1 does not work. In this way, the heating resistor R3 connected to the first capacitor C1 will not resonantly heat the herbal plant extract.

[0153] When the third alternating voltage switch K3 is turned on and the first alternating voltage switch K1 and the second alternating voltage switch K2 are both turned off, the third inductor L3, the first capacitor C1 and the second capacitor C2 are configured to collectively resonate at a third preset working frequency band, so that the heating resistors R3 and R4 collectively resonantly heat the medical drugs.

[0154] 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.

[0155] 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.

[0156] Second circuit structure embodiment:

[0157] 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.

[0158] 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.

[0159] 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.

[0160] In the embodiment, the resonance control circuit comprises at least two heating resistors, at least one capacitor C and at least two inductors L.

[0161] Specifically, refer to Figure 10 , Figure 10 is a circuit connection diagram of another resonance control circuit in the embodiment of the application. It can be known that the resonance control circuit in the embodiment comprises a controller 1001, a voltage inductance resonance module 1002, a heating module 1003 and a power supply 1004. Figure 10

[0162] In the resonance control circuit in the embodiment, the number of capacitors C is less than the number of heating resistors R, as shown in Figure 10 , the inductor L in the voltage inductance resonance module 1002 can comprise a first inductor L1 and a second inductor L2, the alternating voltage switch K can comprise a first alternating voltage switch K1 and a second alternating voltage switch K2, the capacitor C can comprise a first capacitor C1, and the heating resistor R in the heating module 1003 can comprise 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 the other end of the first capacitor C1 and one end of the fourth heating resistor R4 are connected to the first node A respectively.

[0163] In the case that the first alternating voltage switch K1 is turned on and the second alternating voltage switch K2 is turned off, the first inductor L1 and the first capacitor C1 are configured to generate resonance in the first preset working frequency band, so that the third heating resistor R3 connected to the first capacitor C1 performs resonance heating on the herbal plant extract, and at the same time, the first inductor L1 directly transmits the alternating voltage U1 of the alternating current power supply to the fourth heating resistor R4, so that the fourth heating resistor R4 performs non-resonance heating on the herbal plant extract. In other words, at this time, the third heating resistor R3 and the fourth heating resistor R4 work simultaneously.

[0164] In the case that the second alternating voltage switch K2 is turned on and the first alternating voltage switch K1 is turned off, the second inductor L2 is configured to transmit the second alternating voltage U2 of the alternating current power supply to the fourth heating resistor R4, so that the fourth heating resistor R4 performs non-resonance heating on the herbal plant extract, and at the same time, since the working frequency band of the first capacitor C1 and the working frequency band of the second inductor L2 are different, the first capacitor C1 does not work and does not transmit the second alternating voltage U2 to the third heating resistor R3, so that the third heating resistor R3 does not work.

[0165] ​That is, the resonance control circuit in the embodiment can be regarded as a main heating resistor or a main heating wire in the electronic atomization device, because the fourth heating resistor R4 can always heat the herbal plant extract without resonance, no matter which AC voltage switch is turned on; while the third heating resistor R3 can be regarded as a sub-heating resistor or a sub-heating wire in the electronic atomization device, because the third heating resistor R3 can only heat the herbal plant extract with resonance when the first AC voltage switch K1 is turned on.

[0166] Figure 10 In the embodiment, when the DC voltage switch is turned on, only the fourth heating resistor R4 can heat the herbal plant extract without resonance. In the embodiment, the power supply 1004 can further include a DC power supply configured to provide a DC voltage U4 to the fourth heating resistor R4, and the fourth heating resistor R4 can heat the herbal plant extract without resonance.

[0167] 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 one by one.

[0168] 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 can heat the herbal plant extract without resonance. At the same time, the third heating resistor R3 is connected to the first capacitor C1, and the third heating resistor R3 cannot heat the herbal plant extract without resonance due to the characteristic of the capacitor passing AC and blocking DC, so the third heating resistor R3 does not work.

[0169] In the embodiment, please refer to Figure 11 , Figure 11 The voltage waveform timing diagram applied to the third heating resistor R3 and the fourth heating resistor R4 in another resonance control circuit in the embodiment. Figure 11 In the upper graph, the horizontal axis is time T, and the vertical axis is the voltage U applied to the third heating resistor R3. In the lower graph, the horizontal axis is time T, and the vertical axis is the voltage U applied to the fourth heating resistor R4.

[0170] If the power supply 1004 only includes an AC power supply, the controller 1001 only controls the AC power supply to be provided to the first inductor L1 and the second inductor L2.

[0171] In the embodiment, the power supply 1004 can include an AC power supply and a DC power supply. Figure 11It can be seen that when the controller receives the first input signal within the first preset time T1, and reads the first preset working frequency band and the first AC voltage U1 parameter of the first input signal, then controls the first AC voltage switch K1 to be turned on and the second AC voltage switch K2 to be turned off according to the read parameters, and 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 working frequency band, and applies the first AC voltage U1 to the third heating resistor R3, so that the third heating resistor R3 resonantly heats the tobacco extract. At the same time, the fourth heating resistor R4 is heated without resonance due to the application of the first AC voltage U1.

[0172] When the controller receives the second input signal within the second preset time T2, and reads the working frequency band and voltage parameter of the second input signal, then controls the second AC voltage switch K1 to be turned on and the first AC voltage switch K1 to be turned off according to the read parameters, and the second inductor L2 then transmits the second AC voltage U2 directly to the fourth heating resistor R4, and the fourth heating resistor R4 is heated without resonance by the application of the second AC voltage U2. At the same time, the first capacitor C1 does not resonate because the working frequency band is different from that of the second inductor L1, and no voltage is applied to the third heating resistor R3 at this time, i.e. the resistance of the third heating resistor R3 is 0, and the third heating resistor R3 does not heat.

[0173] If the power supply only includes a DC power supply, the controller 1001 controls the DC power supply switch to be turned on to provide the DC power supply U4 to the fourth heating resistor R4.

[0174] If the power supply 1004 includes both an AC power supply and a DC power supply, the controller 1001 can control the provision of the DC power supply to the third heating resistor R3 and the fourth heating resistor R4 at the same time as, or before, or after, controlling the provision of the AC power supply to the first inductor L1, the second inductor L2 and the third inductor L3. Please refer to Figure 12 , Figure 12 Voltage waveform diagram of another resonance control circuit in the embodiment of the application. Figure 12 The horizontal axis of the upper, middle and lower graphs is time T, and the vertical axis of the upper graph is the voltage U applied to the third heating resistor R3, and the vertical axis of the lower graph is the voltage U applied to the fourth heating resistor R4.

[0175] From Figure 12The voltage waveform can know that the power supply in the resonance control circuit includes AC power supply and DC power supply, and the resonance control circuit provides the first AC voltage U1 to the third heating resistor R3 and the fourth heating resistor R4 in the first preset time T1, provides the second AC voltage U2 to the fourth heating resistor R4 in the second preset time T2, and provides the DC voltage U4 to the fourth heating resistor R4 in the fourth preset time T4. In the embodiment, the fourth preset time T4 coincides with the second preset time T2, and due to the characteristics of the capacitor passing through AC and blocking DC, the DC voltage U4 will not be applied to the third heating resistor R3.

[0176] It should be noted that, Figure 12 The amplitude of the DC voltage U4 shown in the figure is the amplitude of the second AC voltage U2 marked in the vertical axis to the part of the DC voltage U4. In this case, as shown in Figure 12 The DC voltage U4 will be superimposed with the second AC voltage U2 in the second preset time.

[0177] In the embodiment, since the power supply voltage is always transmitted to the fourth heating resistor R4 during the power-on process, and 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 a vice heating mode, providing a continuous and always changing heating voltage for the working substance. Therefore, the user can select different heating modes according to actual needs to obtain the required heated or atomized working substance.

[0178] The resonance control circuit in the embodiment of the application is described in detail above, and the resonance control method in the embodiment of the application is described below.

[0179] The resonance control method in the embodiment of the application includes the resonance control circuit and the voltage waveform timing diagram shown in the foregoing Figures 1 to 12 The resonance control circuit and the voltage waveform timing diagram shown in the foregoing

[0180] The resonance control circuit used in the resonance control method in the embodiment of the application is as shown in the foregoing Figure 1 The resonance control method in the embodiment of the application can include the following steps in the total preset time:

[0181] The controller 101 selects a corresponding different working frequency band according to different input signals to control the capacitor-inductor resonance module 102 to generate a corresponding different resonance;

[0182] 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.

[0183] Power supply 104 provides power voltage to controller 101 and capacitor-inductor resonant module 102;

[0184] The heating module 103 resonates and heats the working substance according to the different resonances generated by the capacitor-inductor resonant module 102.

[0185] 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.

[0186] The following description, with reference to the foregoing, explains the resonance control methods associated with various circuit connection methods in the specific embodiments.

[0187] 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.

[0188] Please see Figure 3 , Figure 3 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:

[0189] 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.

[0190] In the second preset time length T2, the controller 201 controls the second AC voltage switch K2 to be turned on according to the second input signal, the first AC voltage switch K1 and the third AC voltage switch K3 are both turned off, and the second capacitor C2 and the second inductor L2 are configured to resonate at the second preset working frequency band by the second AC voltage U2, so that the heating resistor R2 connected to the second inductor L2 resonantly heats the working substance, and the second input signal contains a parameter set of the second AC voltage.

[0191] In the third preset time length T3, the controller 201 controls the third AC voltage switch K3 to be turned on according to the third input signal, the first AC voltage switch K1 and the second AC voltage switch K2 are both turned off, and the third capacitor C3, the first inductor L1 and the second inductor L2 are configured to resonate at the third preset working frequency band by the third AC voltage U3, so that the two heating resistors R1 and R2 jointly resonantly heat the working substance, and the third input signal contains a parameter set of the third AC voltage U3, and the third preset working frequency band is a frequency band in which the first preset working frequency band and the second preset working frequency band overlap.

[0192] It should be noted that the total preset time length T can include the first preset time length T1, the second preset time length T2 and the third preset time length T3.

[0193] In addition, due to the alternating resonant heating of the working substance by the two heating resistors R1 and R2, the circuit connection mode and the resonant control method can be understood as the case where the heating resistors are not divided into main and auxiliary heating wires.

[0194] In the embodiment, the voltage waveform of the heating resistor shown in Figure 3 may be further decomposed into the voltage waveform of each of the heating resistors R1 and R2. Please refer to Figure 13 , Figure 13 for the voltage waveform decomposition diagram of the heating resistor in the embodiment of the present application. Figure 3 As shown in Figure 13 , Figure 13 is the voltage waveform diagram of each of the heating resistors R1 and R2, which can also be called a voltage timing diagram.

[0195] Further, when the power supply further includes a direct current power supply, please refer to Figure 14 , Figure 14 for the voltage waveform decomposition diagram of the heating resistor. Figure 4

[0196] The resonant control method in the embodiment of the present application is described as follows:

[0197] ​In the fourth preset time length T4, the controller 201 controls the direct current voltage switch K4 to be turned on according to the fourth input signal, and the first inductor L1 and the second inductor L2 respectively transmit the direct current voltage U4 of the direct current 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.

[0198] It should be noted that the total preset time length T can further include the fourth preset time length T4, which does not coincide, partially coincides or completely coincides with any one or more of the first preset time length T1, the second preset time length T2 and the third preset time length T3.

[0199] In this embodiment, the fourth preset time length T4 is the sum of the first preset time length T1, the second preset time length T2 and the third preset time length T3, that is, the resonant control circuit is always providing the direct current power supply while providing the alternating current power supply.

[0200] The second kind: the heating resistor R is connected with the inductor L, and the number of the inductor L is less than the number of the heating resistor R:

[0201] Please refer to Figure 6 , Figure 6 The voltage waveform diagram of the resonant control method of the resonant control circuit based on Figure 5 The resonant control method of the resonant control circuit in the embodiment of the application is as follows when the power supply is an alternating current power supply:

[0202] In the first preset time length T1, the controller 501 controls the first alternating current voltage switch K1 to be turned on according to the first input signal U1, and the second alternating current voltage switch K1 is turned off. The first capacitor C1 and the first inductor L1 are configured to generate resonance through the first alternating current voltage U1 in the first preset working frequency band, so that the first heating resistor R1 connected with the first inductor L1 performs resonant heating on the working substance, and the first capacitor C1 transmits the first alternating current voltage to the second heating resistor R2, so that the second heating resistor R2 performs non-resonant heating on the working substance. The first input signal contains a parameter set of the first alternating current voltage U1.

[0203] In the second preset time length T2, the controller 501 controls the second alternating current voltage switch K2 to be turned on according to the second input signal, and the first alternating current voltage switch K1 is turned off. The second capacitor C2 is configured to transmit the second alternating current voltage U2 to the second heating resistor R2, so that the second heating resistor R2 performs non-resonant heating on the working substance, and the first heating resistor R1 does not work.

[0204] It should be noted that the total preset time length T can include the first preset time length T1 and the second preset time length T2.

[0205] Further, when the power supply further comprises a direct current power supply, please refer to Figure 7 The resonance control method in the embodiment of the application is described as follows:

[0206] In the fourth preset time duration T4, the controller controls the direct current voltage switch K4 to be turned on according to the fourth input signal, and the inductor L transmits the direct current voltage U4 of the direct current power supply to the heating resistors R1 and R2, so that the first heating resistor R1 and the second heating resistor R2 perform non-resonance heating on the working substance.

[0207] In the embodiment, the fourth preset time duration T4 is after the second preset time duration T2, and thus is completely not overlapped with the first preset time duration T1 and the second preset time duration T2, and thus the direct current voltage U4 applied to the first heating resistor R1 and the second heating resistor R2 in the fourth preset time duration T2 will not be overlapped and superimposed with the first alternating current voltage U1 and the second alternating current voltage U2.

[0208] The circuit connection mode and the resonance control method in the embodiment can be understood as the case that the heating resistors are not divided into main and auxiliary heating filaments.

[0209] The third: the heating resistors R are connected with the capacitors C, and the number of the heating resistors R is the same as that of the capacitors C:

[0210] Please refer to Figure 9 Figure 9 The voltage waveform diagram of the resonance control method of the resonance control circuit shown in Figure 8 The resonance control method of the resonance control circuit in the embodiment of the application is described as follows when the power supply is an alternating current power supply:

[0211] In the first preset time duration T1, the controller 801 controls the first alternating current voltage switch K1 to be turned on according to the first input signal, the second alternating current voltage switch K2 and the third alternating current voltage switch K3 are both turned off, the first inductor L1 and the first capacitor C1 are configured to generate resonance through the first alternating current voltage U1 in the first preset working frequency band, so that the heating resistor R3 connected with the first capacitor performs resonance heating on the working substance, and the first input signal contains a parameter set of the first alternating current voltage U1.

[0212] In the second preset time duration T2, the controller 801 controls the second alternating current voltage switch K2 to be turned on according to the second input signal, and in the case that the first alternating current voltage switch K1 and the third alternating current voltage switch K3 are both turned off, the second inductor L2 and the second capacitor C2 are configured to generate resonance through the second alternating current voltage U2 in the second preset working frequency band, so that the heating resistor R4 connected with the second inductor L2 performs resonance heating on the working substance, and the second input signal contains a parameter set of the second alternating current voltage U2.

[0213] ​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.

[0214] 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.

[0215] 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.

[0216] 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.

[0217] 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.

[0218] 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.

[0219] 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:

[0220] In the first preset time length T1, the controller 1001 controls the first AC voltage switch K1 to be turned on and the second AC voltage switch K2 to be turned off according to the first input signal U1, and the first inductor L1 and the first capacitor C1 are configured to resonate at the first preset working frequency band by the first AC voltage U1, so that the third heating resistor R3 connected with the first capacitor C1 resonantly heats the working substance, and the fourth heating resistor R4 non-resonantly heats the working substance.

[0221] In the second preset time length T2, the controller 1001 controls the second AC voltage switch K2 to be turned on and the first AC voltage switch K1 to be turned off according to the second input signal, and 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 non-resonantly heats the working substance, and since the working frequency band of the second inductor L2 and the working frequency band of the first capacitor C1 are different, the second AC voltage U2 is not transmitted to the third heating resistor R3, and the third heating resistor R3 does not work.

[0222] It should be noted that the total preset time length T can include the first preset time length T1 and the second preset time length T2.

[0223] In the embodiment, since the fourth heating resistor R4 is always non-resonantly heated in the first preset time length T1 and the second preset time length 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.

[0224] Further, when the power supply further includes a direct current power supply, please refer to Figure 12 The resonance control method in the embodiment of the application is as follows:

[0225] In the fourth preset time length T4, when the controller 1001 controls the direct current voltage switch K4 to be turned on according to the fourth input signal, the direct current voltage U4 of the direct current power supply is transmitted to the fourth heating resistor R4, so that the fourth heating resistor R4 non-resonantly heats the working substance, and since the first capacitor C1 cannot transmit the direct current voltage U4 to the third heating resistor R3, the third heating resistor R3 does not work, and the fourth preset time length T4 does not coincide with, partially coincides with or completely coincides with any one or more of the first preset time length T1 and the second preset time length T2.

[0226] It should be noted that, by Figure 12 It can be known that the fourth preset time length T4 in the embodiment completely coincides with the second preset time length T2, so that the second AC voltage U2 transmitted to the fourth heating resistor R4 in the second preset time length T2 (i.e. the fourth preset time length T4) will be superimposed with the direct current voltage U4, thereby increasing the heating power of the fourth heating resistor R4.

[0227] In the resonance control method of the embodiment, since the fourth heating resistor R4 can always have power supply voltage transmitted thereto during energization, and the third heating resistor R3 can only work when the first AC voltage switch K1 is turned on, the two heating resistors work as a main and a backup heating mode to provide the working substance with a continuous and always-varying heating voltage, so that the user can select different heating modes according to actual needs to obtain the working substance after heating or atomization.

[0228] The resonance control method of the resonance control circuit in the embodiment is described in detail above, and the electronic atomization device provided by the embodiment includes the resonance control circuit and the resonance control method described above. Figures 1 to 14 The technical contents of the resonance control circuit and the resonance control method are not repeated here.

[0229] The electronic atomization device in the embodiment can cause the working substance to be heated or atomized in different conditions and different situations, so that the heated working substance has various forms, can meet the diversified needs of the user, and can reduce the generation of local carbon deposition in the heating module part, prolong the service life of the heating module, and improve the purity of the working substance after heating or atomization, thereby improving the use performance of the working substance and the user experience of the user.
