The output electrode 220 is electrically connected to the RF energy generating circuit 440, the current collecting circuit 410, the processor 420, the control circuit 430, and the driving circuit 470, and the driving circuit 470 is further electrically connected to the current collecting circuit 410. Temperature sensor 230 is electrically coupled to processor 420, which is electrically coupled to control circuit 430.

The current collecting circuit 410 is configured to collect an input current of the RF energy generating circuit 440 and send it to the processor 420. Further, the current collecting circuit 410 includes a sampling resistor and an amplifying power The circuit, the output electrode 220, the sampling resistor and the amplifying circuit are electrically connected in sequence, and the input current of the RF energy generating circuit 440 is collected by the sampling resistor and amplified by the amplifying circuit and then sent to the processor 420.

The processor 420 is configured to analyze the input current of the RF energy generating circuit 440 to obtain a first analysis result and send the result to the control circuit 430. Preferably, the processor may be a single chip microcomputer.

The control circuit 430 is configured to send a first control signal to the driving circuit 470 according to the first analysis result, to control the magnitude of the radio frequency energy emitted by the radio frequency energy generating circuit 440 by using the driving circuit 470, where the radio frequency energy generating circuit 440 is used. Radio frequency energy is transmitted to the output electrode 220. For example, when the input current of the RF energy generating circuit 440 is large, the control circuit 430 may send the first control signal to the driving circuit 470 according to the first analysis result to control the RF energy generating circuit 440 to emit a small RF energy, corresponding to The output electrode 220 outputs a small RF energy, and at the same time, the voltage is adjusted by the transformer 480, so that the input current of the RF energy generating circuit 440 is also adjusted to be small at the same time; when the input current of the RF energy generating circuit 440 is small, the control is performed. The circuit 430 can send the first control signal to the driving circuit 470 according to the first analysis result to control the RF energy generating circuit 440 to generate a large RF energy.
