[0023] Air outlet holes are evenly arranged at the lower end of the high-voltage transformer box 1, and a circulating fan 501 is fixedly installed inside the drying air outlet duct 5 to accelerate the air flow inside the device. Exhaust holes are arranged around the drying air outlet duct 5, and an annular one-way breathable membrane 502 is slidably clamped inside the drying air outlet duct 5 to prevent external moisture from entering the interior of the device.

[0024] The lower surface of one side of the protective cover 6 is hinged to the high-voltage transformer box 1, and a sealing slot is provided on the other side of the protective cover 6, and a sealing strip 601 is provided on the other side of the protective cover 6.
