The utility model relates to the technical field of hair driers, in particular to a hair drier capable of reducing use
noise through a conical sound absorption structure. Comprising a blower body with an air inlet and an air outlet, a fluid channel which enters the air outlet along the air inlet and flows out is arranged in the blower body, a high-speed fan and a heating module are arranged in the fluid channel, the heating module is arranged at the air outlet and the high-speed fan, and a conical inner shell is arranged in the fluid channel. The end, with a small opening, of the conical inner shell is in
butt joint with the air inlet, the end, with a large opening, of the conical inner shell is in
butt joint with the high-speed fan, a plurality of evenly-distributed long holes are formed in the wall face of the conical inner shell in a surrounding mode, a sound absorption cavity is formed between the conical inner shell and the inner wall of the blower body, and a sound
absorption layer is arranged in the sound absorption cavity. And the sound
absorption layer arranged in the sound absorption cavity can play a powerful sound absorption role. When sound
waves generated when the blower works enter the sound absorption cavity through the long holes, the sound
absorption layer can efficiently absorb and convert
sound wave energy, and therefore
noise transmission is greatly reduced.
