[0053] The buttons are integrated on the chip U2. When a button is pressed, it will actively send a specific value to the main control module 1. The main control module 1 will receive the button value and execute the corresponding action. The buttons, as shown in S1~S5, are connected between the K1 pin and the KS1~KS5 pins of the chip U2 and will be automatically scanned.

For the specific connection relationships between these components, please refer to [reference needed]. Figure 7 .
[0064] The non-isolated power module 7 is similar to a DC-DC step-down circuit. The power chip U7 uses the BP2571D chip from Chipone Technology, a non-isolated step-down constant voltage chip that directly samples the output voltage.
[0065] The alternating current is rectified by the full-bridge rectifier D8 into pulsating direct current. After passing through inductor L1 and capacitor CT1, it becomes a high-voltage DC current of about 300V and is sent to the HV pin (internal high-voltage power transistor) of the power chip U7.
