[0029] An inner cavity 3 is provided inside the rotating shaft 2, and a first air outlet 4 is provided on the outer wall of the rotating shaft 2. The first air outlet 4 is connected to the inner cavity 3. When in use, a plurality of first air outlets 4 are provided. During the rotation of the rotating shaft 2, air is supplied to the surroundings by the first air outlets 4 to ensure uniform drying. A first turntable 5 is fixedly connected to the middle section of the rotating shaft 2, and a second turntable 6 is rotatably provided on the first turntable 5. The second turntable 6 is provided in plurality, and the plurality of second turntables 6 are evenly distributed around the rotating shaft 2. The rotation of the motor 9 drives the rotating shaft 2 to rotate, so that the first turntable 5 rotates synchronously, and the second turntable 6 also rotates around the rotating shaft 2. A hook 17 is fixedly connected to the lower surface of the second turntable 6. The top of the second turntable 6 is used to directly place objects, and the hook 17 is provided for hanging objects.

[0030] A gear ring 7 is provided inside the housing 1, and a support plate 18 is fixedly connected between the gear ring 7 and the inner wall of the housing 1.

During the rotation of the first rotating disk 5, the second rotating disk 6 will also rotate when it rotates around the rotating shaft 2 because the gear 8 is meshed with the gear ring 7.

[0031] The utility model is provided with structures such as the first turntable 5, the second turntable 6, the gear 8 and the gear ring 7. When the second turntable 6 rotates around the rotating shaft 2, it will also rotate, thereby driving the objects to rotate.

[0032] Taking into account that more water vapor will be generated during the drying process, an annular cavity 15 is opened inside the wall of the box body 1, and a second air outlet 16 is opened on the top of the inner wall of the box body 1. The second air outlet 16 is provided in plurality and is connected to the annular cavity 15 to extract water vapor through the second air outlet 16 and the annular cavity 15.

When the rotating shaft 2 rotates, the first air outlet 4 blows air to the surroundings to achieve drying of the items.

[0035] Since the first air outlet 4 supplies air outwards during the rotation process, direct wind blowing can be avoided and the uniformity of air drying can be further improved.

[0036] During the operation of the blower 12, the high-temperature water vapor inside the box 1 is sucked into the annular cavity 15 through the second air port 16, and transported to the heating box 13 through the second air duct 14, where it is condensed, dried, and heated, and then transported to the inside of the box 1;

[0037] As the high-temperature water vapor flows from top to bottom in the annular cavity 15 , the temperature of the side wall of the box body 1 rises, which has a heat preservation effect, effectively utilizes heat energy, and further improves the drying efficiency.
