[0021] An arc-shaped guide plate 304 is fixedly connected at each air outlet in the heating chamber 102 . The arc-shaped guide plate 304 can better guide the hot air blown out by the hot air motor 401 from the air outlet, so that the hot air is blown from the heating chamber 102 into the drying chamber 101 .

[0022] The hot air motor 401 is coaxially arranged with the electric heater 402, and the electric heater 402 is a spiral electric heating tube, which further improves the efficiency of hot air blowing and heating.

[0023] The limit plate 8 is a plate body with a rectangular groove in the middle. The limit plate 8 is used to support the support plate 9. The limit plate 8 is arranged corresponding to the air outlets on both sides of the middle partition 303. During maintenance, the limit plate 8 will not interfere with the limit plate 8 when the middle partition 303 is disassembled and turned over.

[0024] A dustproof net is provided at the air inlet in the middle of the middle partition 303, and the dustproof net can reduce the dust from flowing into the heating chamber 102. The middle partition 303 is detachably connected to the upper partition 301 through a screw.

[0025] The rubber ring 5 is coaxially arranged with the rotating platform 6, and an arc-shaped protrusion is provided on the upper end of the rubber ring 5. The side wall of the roller 702 is provided with a groove corresponding to the arc-shaped protrusion. When the rotating table of the rotating platform 6 rotates, the barrel 7 rotates under the action of friction, and the arc-shaped protrusion can prevent the barrel 7 from being misaligned up and down during rotation.

[0026] The limit plate 8, the first temperature sensor 10 and the second temperature sensor 11 are all fixedly connected to the box body 1. The first temperature sensor 10 and the second temperature sensor 11 are respectively located on the upper and lower sides of the box body 1. When temperature control is performed, if one of the first temperature sensor 10 and the second temperature sensor 11 is damaged, the other one can continue to perform temperature detection and control whether the thermoelectric blower 401 and the electric heater 402 continue to heat.

[0027] The working principle of the present invention is: when the present invention is in use, hot air is generated by the hot air motor 401 and the electric heater 402, which is introduced into the drying chamber 101 through the air outlet, and returns to the heating chamber 102 through the air inlet for circulation. The temperature of the drying chamber 101 is monitored by the first temperature sensor 10 and the second temperature sensor 11 to determine whether the hot air motor 401 and the electric heater 402 continue to heat so as to keep the temperature constant. When the air inlet needs to perform multi-layer drying, a limit plate 8 of a suitable height can be selected according to the specifications of the items to be dried to insert the support plate 9 to place the items; when rotary drying is required, the tray 9 is removed, and the roller 702 of the barrel 7 is placed downward along the slot 601, so that the arc-shaped protrusion on the rubber ring 5 is stuck in the corresponding groove of the roller. After that, when the rotating platform 6 rotates, the barrel 7 rotates under the action of friction (either the support plate 9 or the barrel 7 can be used).
