High and low voltage power supply for range hood purification with ignition protection and arc suppression

This high-voltage power supply for range hood purification includes: a fixed plate with high-temperature insulation coating and the high-voltage power supply unit. Through the configured upper insertion plate, lower insertion plate, spring expansion plate, rotating shaft, and sliding plate, the high-voltage power supply unit can be quickly installed and fixed. It also allows for effective adjustment of the distance between the high-voltage power supply unit and the fixed plate, meaning the distance between the high-voltage power supply unit and the inner wall of the purifier's electrical box can be effectively adjusted. Moreover, it facilitates easy disassembly and maintenance of the high-voltage power supply unit.
