The above is a specific embodiment of a one-way valve structure, but it is not limited to the above structure. It can also adopt existing similar mechanical one-way valve products to meet the requirements of opening when the external water tank is installed and closing when it is removed.

[0007] The body has an opening on one side and is provided with a frying basket assembly. The pot mouth of the frying basket assembly in the body is provided with a sealing assembly. When the frying basket assembly is placed in the body, the sealing assembly of the pot body is sealed against the cover mouth of the metal insulation layer above the pot body. The cover mouth of the metal insulation layer is provided with a heating element and a metal centrifugal fan blade. The metal centrifugal fan blade is connected to the transmission shaft of the motor extending into the metal insulation layer. The motor is arranged at the top of the body, and the motor and the heating element are connected to the controller circuit board through the line. The above is the specific implementation structure design of the heating element, the metal centrifugal fan blade, and the sealing assembly.

[0008] An air guide cover is arranged above the metal heat insulation layer at the top of the body, and a plastic centrifugal fan blade is arranged inside the air guide cover. The plastic centrifugal fan blade and the metal centrifugal fan blade are connected to the transmission shaft of the motor at the same time, and an air outlet cover is arranged at the air outlet of the body where the metal heat insulation layer and one side of the air guide cover communicate. The above is a structural embodiment of a double centrifugal fan blade.

[0009] The utility model has reasonable structural design, convenient production and assembly, good sealing effect and low production cost, and is particularly inconvenient to remove, add water and clean the water tank, and has a large water tank capacity. The utility model is mainly used as a water tank split external steam fryer, and is a structural improvement of similar products. BRIEF DESCRIPTION OF THE DRAWINGS
