The fan 3 is turned on to let the external air flow pass through the wind collecting hood 2, the second air duct 4, the heating box 6 and the first air duct 7 in sequence into the sprayer 9, and finally introduced into the drying device body 10. When the air flow enters the heating box 6, the space it flows through suddenly increases, forming a Venturi effect, and the air flow rate slows down. The heating strip 5 is turned on to heat the air flow. When the external air flow passes through the dustproof net 12, the dust floating in the air is filtered by the dustproof net 12 and attached to it. When the air flow passes through the blade 15, it drives the blade 15 and the rotating rod 18 to rotate, and the rotating rod 18 drives the rotating bar 17 to rotate, and the dust on the dustproof net 12 is cleaned by the brush, thereby achieving a good dust removal effect.
