The electric heating part 2.3 is arranged in the inner cavity of the cylinder 2.1, and the top of the cylinder 2.1 is provided with a plurality of air outlets 2.1.1. The electric heating part 2.3 can be a plurality of spiral electric heating pipes.
[0028] The disc-shaped rotating frame 3 comprises an annular plate 3.1 rotatably sleeved on the front end of the inner cavity of the cylindrical shell 1.3, a circular plate 3.2 rotatably sleeved on the rear end of the inner cavity of the cylindrical shell 1.3, a cylindrical net 3.3 fixed on the front end of the annular plate 3.1 and the rear end of the front wall of the circular plate 3.2, and a plurality of net plates 3.4 fixed on the outer peripheral wall of the cylindrical net 3.3 along the radial direction.
