The invention relates to a high pressure kettle which comprises a kettle body component, a kettle cover component connected with the kettle body component in a disassemble way, and a discharge valve arranged on the kettle cover component, wherein, the kettle cover component is provided with an exhaust passage which is communicated with environment and the inside of the kettle body, under an air pressure function, an exhaust valve of the exhaust passage is sealed, and a water out control device controlling the startup of the exhaust valve and the discharge valve are controlled in sequence. The water out control device comprises a valve push rod and a button which is interacted with the valve push rod, after pressing the button, the valve push rod firstly pushes the exhaust valve to move, to ensure that the exhaust valve drains off the high pressure in the kettle, an then the valve push rod only can continuously push the valve to realize backwater, therefore, before the backwater of the high pressure kettle of the invention, the steaming high pressure inside the kettle can be taken off, thereby preventing the boiling water in the kettle from being spouted to scald a human body, therefore, the usage is more convenient and safer. The structure of the high pressure kettle of the invention is simple, the assembly is easy, and therefore, the manufacture cost is lower.
