A heavy pressure jug

Abstract

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.

Description

Technical field: [0001] The invention relates to a high-pressure kettle, in particular to a safety protection technology for a high-pressure kettle. Background technique: [0002] Compared with ordinary kettles, the high-pressure kettle is in a sealed high-pressure state when the liquid is heated, no or only a small part of the steam flows out of the kettle body, and the heat loss is less, so it is more energy-saving when heating the liquid. At the same time, in places where the external atmospheric pressure is low, it can be guaranteed that the water in the high-pressure kettle will only boil when the temperature is 100°C or above. [0003] Because when the water is boiled, the high-pressure kettle will form a large amount of water vapor in the body of the kettle. When pouring water or opening the lid, high-temperature water vapor often sprays out from the spout. However, the high-pressure kettle on the market does not have a pressure relief structure. Especially hands) ar...
