The main function of the overheat protection board is to cut off the power supply when the temperature is too high to prevent equipment damage. The temperature sensor is responsible for monitoring the temperature of the equipment. When the temperature exceeds the preset safety limit, it will trigger the overheat protection board to work, thereby cutting off the power supply and protecting the equipment.

[0029] Specifically, the digital display board 15 integrates a digital display screen and several touch buttons on one side, and a touch switch on the other side.

[0030] In this implementation scheme, the fan 17, PTC heating element 13, and digital display board 15 are all electrically connected to the main control circuit board 14. The touch buttons, touch switches, and digital display screen are integrated into one design, realizing visual adjustment of temperature and wind speed and reducing the error rate.

[0031] Specifically, the main body shell 11 includes a front shell 111 and a rear shell 112, the bracket 12 is disposed between the front shell 111 and the rear shell 112, and a dustproof net 121 located on one side of the bracket 12 is also provided on the side of the PTC heating element 13.

[0032] In this embodiment, the front shell 111 and the rear shell 112 are fixed with screws, and the dustproof net 121, together with the hollow design on one side of the front shell 111, further reduces the contamination of the heating area by dust.

[0033] Specifically, a front cover 18 is provided on the side of the front shell 111 away from the rear shell 112, and a touch panel 181 corresponding to the digital display panel 15 is provided inside the front cover 18.

[0034] In this implementation, users can trigger touch buttons by touching the touch panel 181, making it more convenient to use.
