[0022] Working principle:

[0023] When in use, first control the heater assembly to open to heat the gas in the garbage disposal box, then start the blower motor to drive the fan impeller in the impeller fan assembly 5 to rotate, and then the outside air can be transported to the inner cavity of the garbage disposal box through the through hole 6, so that the input air can continue to be heated by the heater assembly, and the heated gas will flow downward into the garbage disposal box through the opening at the lower end of the heating tank 2, so that the garbage can be dried with hot air through the flowing hot air; thus avoiding the problem of the traditional method of spreading the garbage on the ground for drying, which directly affects the surrounding environment. And the water vapor after hot air treatment in the garbage disposal box will be discharged outward along the air outlet 7 together with the air; in this embodiment, a steam collection device can be installed at the position of the air outlet 7 to filter the discharged gas.

[0024] Embodiment 2, as a further preferred embodiment of embodiment 1, the impeller fan assembly 5 includes a fan housing 51, a hollow circular cavity is arranged in the middle of the fan housing 51, an air outlet 53 is arranged below the fan housing 51, the air outlet direction of the air outlet 53 is tangent to the hollow circular cavity, a fan impeller is installed in the hollow circular cavity, one side of the fan housing 51 is fixedly connected to the blower motor, an air inlet pipe is arranged at the position where the blower motor and the fan housing 51 are connected, a plurality of air inlet holes are opened on the surface of the air inlet pipe, and the other side of the fan housing 51 is sealed and connected to the casing cover 52.

[0025] When in use, the fan impeller is driven by the blower motor to rotate, and then the gas is discharged to the garbage disposal box through the air outlet 53 through the centrifugal force of the fan impeller; and the outside air enters the hollow circular cavity in the middle of the fan housing 51 through the air inlet on the surface of the air inlet pipe 53.
