Rotary cage sealing and coupling device of air oven and air oven

The utility model relates to a rotating cage sealing and coupling device of an air oven. The rotating cage sealing and coupling device comprises a motor, a first coupling assembly, a fixing support and a rotating cage assembly. Wherein the first coupling assembly comprises a transmission wheel driven by the motor and a sealing ring arranged outside the transmission wheel in a sleeving mode, the fixing support is clamped between the sealing ring and the motor, and the rotating cage assembly is detachably connected with the transmission wheel. The motor drives the transmission wheel to rotate axially through the motor shaft, and the transmission wheel further drives the rotating cage assembly to rotate axially. The utility model further provides an air oven comprising the rotary cage sealing coupling device. 本实用新型涉及一种空气烤箱的转笼密封耦合装置，包括电机、第一耦合组件、固定支架及转笼组件。其中，所述第一耦合组件包括通过所述电机驱动的传动轮和套设于所述传动轮外的密封圈，所述固定支架被夹设于所述密封圈与所述电机之间，所述转笼组件与所述传动轮可分离的连接。所述电机通过所述电机轴驱动所述传动轮做轴向旋转，并且所述传动轮进一步驱动所述转笼组件轴向旋转。本实用新型还提供了一种包括所述转笼密封耦合装置的空气烤箱。
