[0039] The present invention is further described in detail below in conjunction with a specific circuit diagram:

[0040] like Fig.10 As shown, Fig.10 The circuit structure diagram of the atomization drive circuit of the utility model is shown, and the atomization power supply circuit 21, the switch tube control circuit 22, the discharge circuit 23 and the filter circuit 24 are described below respectively:

Wherein, the switch tube Q1 is preferably a high-power MOS tube, specifically an NMOS tube.

[0046] During operation, the main controller outputs a PWM control signal to control the NMOS tube to conduct quickly, so that the filter circuit 244 is in a loop conduction state. At this time, the current signal of the filter circuit 244 is detected and fed back to the main controller, so that the main controller adjusts the operating frequency of the PWM control signal according to the current detection signal and outputs it to re-drive the NMOS tube to conduct. The operating frequency is adjusted cyclically in the above manner until it is consistent with the resonant frequency of the atomizer Y1, so that the atomizer Y1 can work in the best state of atomization.

[0053] By setting two groups of RC filter circuits 241 to filter the current signal, the clutter is filtered out, the signal stability and signal detection accuracy are improved, and thus the signal frequency control accuracy is improved.

[0054] like Fig.11 As shown, the present invention further provides an atomizer, comprising a machine body 9 and the above-mentioned multiple atomizer drive devices 91 , wherein the multiple atomizer drive devices 91 are installed in the machine body 9 .

In addition, the driver with high heat generation is integrated into the heat dissipation housing of the power supply device, and the heat dissipation housing is used to dissipate heat for the power supply and the driver at the same time, which can reduce the external occupied space and reduce the cost of heat dissipation devices.

[0056] Secondly, the driver has various functions. By setting a filter circuit to filter the detection signal, the noise is filtered out, the signal stability and signal detection accuracy are improved, and thus the signal frequency control accuracy is improved; at the same time, the switch control circuit is set to control the conduction of the filter circuit according to the current control signal to feed back the detection signal to the main controller, so that the main controller adjusts the operating frequency of the control signal according to the detection signal until the operating frequency of the control signal is consistent with the resonant frequency of the atomizer, and the atomizer is driven to work stably and the atomization effect is good. In addition, the set discharge circuit and the control signal with high driving ability can improve the switching efficiency of the switch tube control circuit, thereby improving the frequency adjustment efficiency, and then improving the atomization control efficiency, so that the atomizer can work stably in the best state as soon as possible, and improve the atomization driving effect.
