[0002] With the improvement of people's living standards, the oil-free cooking method of air fryers is becoming more and more popular. When cooking in traditional air fryers, steam is usually introduced into the cooking cavity for steam cooking or high-temperature air is introduced into the cooking cavity for air frying. In order to prevent excessive pressure in the cooking cavity, the air fryer is also provided with an exhaust channel for exhausting excess gas in the cooking cavity. However, since the exhaust channel of the traditional air fryer is not adjustable and the amount of steam in the cooking cavity needs to be maintained during steam cooking, steam cooking and air frying cooking can only be set separately in the corresponding air fryer, which has poor applicability and practicality, and the user experience is not good.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

The first fixing hole 411 and the second fixing hole 412 can not only position the rotating shaft of the driving motor 431 to reduce the difficulty of installing the driving motor 431, but also limit the rotating shaft of the driving motor 431 to effectively improve the stability of the driving motor 431 driving the valve core 42 to rotate.
