图4是专用高频振荡电路原理图。Figure 4 is a schematic diagram of a dedicated high-frequency oscillator circuit.

图5是针体结构示意图。Fig. 5 is a schematic diagram of the structure of the needle body.

如图1所示，本发明的电火针由高频电源1、针体总成2和将这两者连接起来的4芯电缆3所组成。高频电源1产生低压高频电通过四芯电缆3送到针体内的感应线圈L₄发生热量，达到加热针尖的目的。As shown in Figure 1, the electric fire needle of the present invention is made up of high-frequency power source 1,needle body assembly 2 and the 4-core cable 3 that these two are connected.

The DC stabilizedpower supply 4 consists of a power transformer with a secondary voltage of 28V and a current of 2A, a rectifier bridge of 3A and 100V, a continuously adjustable three-terminal integrated voltage regulator LMs17 and a high-power transistor for expanding the output current Composed of 3CD5D. The whole circuit is a typical current expansion LM317 application circuit, and its output voltage can be continuously adjusted within the range of 0-37V by a potentiometer.

This high-frequency oscillating circuit is a transformer feedback sine wave oscillator. Since there is no requirement for the quality of the waveform, it only pays attention to reducing power consumption and improving energy conversion efficiency. Therefore, the oscillating triode BG₃ is operated in the switch state, and the output waveform is a pulse wave. Not a sine wave.
