The household oven is a food cooking appliance commonly used in daily life of people, can process food materials in a mode of baking food, is convenient for people to eat, is widely applied in daily family use, provides convenience for the life of people, improves the life quality of people, and is popular with people. An industrial oven is a device used in industry to dry products, and is also called oven, drying box, etc. The oven is an electric heating appliance for baking food by using radiation heat emitted by an electric heating element, and can be used for making roast chicken, roast duck, baked bread, cakes and the like. The temperature of the oven is typically adjusted from 50 degrees celsius to 250 degrees celsius depending on the needs of the baked goods. In addition, a new type of oven, called an "air oven," has also been developed in recent years. The air oven is a cooking appliance for baking food by using a circulating air flow of hot air emitted by an air heating assembly and a fan. Air ovens are commonly used to process pasta, such as bread, pizza, or snacks such as egg tarts, cookies, and the like.

While existing ovens consist essentially of an outer shell, an inner cavity, and a heating element, air ovens typically also include an air heating element. In the oven in the prior art, no matter the oven adopts a radiation heating mode or a mode of heating in combination with air, a radiation area of heat radiation or an area covered by hot air flow is limited to a part of the surface of food, if food is not properly stirred in a cooking process, only a part of the food corresponding to a heating area can be contacted with enough high-temperature radiation or air flow to enable the food to be completely cooked, and parts of the food in other areas are not contacted with enough high temperature and are not cooked frequently. Therefore, the user must turn the food once every certain period of time to uniformly heat all the areas of the food, but such manual turning operation causes considerable inconvenience to the user.

In order to solve the problems, the air oven in part of the prior art realizes the function of turning over food by additionally arranging a rotating cage.

When using an air oven with a rotating cage, it is first necessary to fill food into the rotating cage, then close the rotating cage and turn on the oven for heating. In prior art rotary basket devices, the air oven operates to sufficiently heat the food by tumbling in the rotary basket. Nevertheless, the rotating cage of the air oven in the current market has the problem of easy locking under the working condition of high temperature, and in addition, the rotating cage is difficult to take out from the air oven when being locked without a resetting device. In addition, under the transmission mode of prior art, the problem that the motor drive rotating cage in-process still has the easy slip still, influences the durability of air oven to the user experience of product has been influenced.

Therefore, a revolving cage device with reasonable design needs to be provided for the air oven, and the durability and the reliability of the revolving cage device can be ensured while the function of turning over food in the cooking process can be realized.
