Delay closing safety valve for electric pressure cooker

Abstract

A delay closing safety valve for electric pressure cooker is characterized in that the top end of a valve holder is connected with a closing seat by adopting a pin shaft positioning connecting structure; a sealing cushion is positioned between the closing seat and a sealing gland; as the sealing gland compacts a sealing pad; the compressing force of the sealing gland for the sealing pad is a spring force and the spring force is formed by an elastic mechanism in the valve body; a temperature control piece is positioned between the sealing pad and the sealing gland; the deformation travel of the temperature control piece is greater than the distance between the sealing pad and a through hole outlet of the closing seat; when the set temperature is reached, the deformation of the temperature control piece drives the sealing pad to close the through hole outlet of the closing seat. The delay closing safety valve for the electric pressure cooker has the advantages when the electric pressure cooker boils rice to be boiled, rice in the cooker is continuously boiled till rice grains fully suck water content, then the cooker enters the meal pressurizing and stuffing states, and the rice grains boiled by the process are soft and dry, are chewy after being eaten and has obvious rice flavor; the delay closing safety valve is reasonable in structure, simple in production and mounting, low in cost and suitable for large-scale production.

Description

technical field [0001] The invention relates to a safety valve for an electric pressure cooker, in particular to a time-delayed closing safety valve for an electric pressure cooker. Background technique [0002] At present, due to the explosion-proof function of the electric pressure cooker on the market, its working procedure is to turn on the electricity and heat until the food boils for a short time, and the pressure in the pot is generated, that is, it enters the power-off and pressure-holding state. Electric pressure. Continuously circulate until the food is cooked. This kind of cooking process is convenient and energy-saving for cooking soup with a lot of water, but the effect is not so good for cooking rice. When the rice is just boiling, the electric pressure cooker enters the power-off and pressure-maintaining state. At this time, the rice grains can only soak in the hot water statically. When the electric pressure cooker is turned on again for heating, the rice i...

Problems solved by technology

[0003] Although the present invention firstly invented the electric pressure cooker time-delay closing valve, which solved the above-mentioned problems better, the new problem is that, due to its imperfect structure, the processing and manufacturing and assembly requirements are too high, which affects the production efficiency and cost-effectiveness. high
