The connecting piece is reduced, and the cost is saved. The electric heating air duct, namely the heating cavity 2, is connected with the outer cylinder 1 into a whole to form a part, the motor heat and the fan are arranged on the metal upper cover, and the motor heat and the fan are buckled on the upper part of the electric heating air duct to form a heating cavity. And a plurality of connecting pieces and part of metal parts on the air duct are saved. Compared with the prior art that the outer cylinder 1 and the electric heating air duct, namely the heating cavity 2, are two independent parts, namely a plastic part and a metal part, a certain space is reserved between the two parts, and the heat dissipation area is large.

The application also discloses some embodiments, and the heating cavity 2 is provided with an opening 21, and a cover body 3 is arranged on the opening 21.

The present application also discloses some embodiments, wherein the cover 3 is made of metal material. The cover body 3 is made of metal, a cavity is formed by the cover body 3 and the side wall of the outer barrel part, a fan and an electric heating bracket 51 are fixed on the cover body 3, electric heating is arranged on the electric heating bracket 51, and the fan is located right above the air return opening 12. The electric heating and the holder 51 are shown only in a schematic view in a general position, and do not show the actual shape. A circle of heat insulation cotton 6 is stuck near the electric heating to prevent the temperature from being too high.

The application also discloses some embodiments, and the drying system also comprises a fan structure 4, wherein the fan structure 4 is arranged on the cover body 3;
