[0009] Beneficial effects of the utility model:

[0010] The utility model is provided with a sealing structure. When the kettle cover is pressed on the kettle mouth, the insert ring and the sealing ring will move into the sealing mouth. When the kettle cover and the kettle mouth are locked by the flange, the sealing ring will fit on the inner side of the sealing mouth and be compressed, and the sealing ring will fit tightly on the inner side of the sealing mouth to form a tight isolation area between the two joint parts to prevent leakage of liquid or gas in the reaction kettle. The sealing structure can be directly sealed after the kettle cover and the kettle mouth are installed and fixed, without the need for cumbersome operations such as placing a sealing gasket during the installation process. At the same time, the spring will be compressed and produce elasticity. Under the action of the elasticity, the sealing ring will fit more tightly on the inner side of the sealing mouth, making the two joint parts tighter and improving the sealing effect.
