Background

According to the conventional gas valve structure of gas stove, it mainly includes: the gas valve comprises an air inlet channel for supplying the main gas to flow in, an air chamber connected to the air inlet channel and used for accommodating a closed unit, and an air outlet channel communicated to the air chamber and used for allowing the split gas flowing through the closed unit to flow out towards the outer side of the gas valve.

When the gas stove is used, the rotary knob rotates to drive the closer to rotate, so that the gas chamber and the gas outlet channel form a communicated state, and at the moment, the total supply gas flows through the gas inlet channel, the gas chamber, the closer and the gas outlet channel in sequence and then flows into the inner and outer ring furnace tubes, so that the inner and outer ring furnace surfaces of the furnace end are distributed with supply and shunt gas, and the purpose of ignition, combustion and use is achieved.

Although the above-mentioned initiatives can achieve the originally set purpose and are well complied by the industry and ordinary operators, the applicant makes more effort to research and improve the industry and makes it perfectly practical in view of the research and development and the continuous innovation and breakthrough of the technology in the industry without any residual force; in addition, the author finds that the following problems are still to be improved after undergoing numerous updating experimental tests and inducing the response opinions of the actual operation and use of the consumer:

when general housewives are subjected to stuffy boiling, the stove fire is changed to small fire and then the general housewives are subjected to stuffy boiling, at the moment, if temporary affairs need to be dealt with urgently, the housewives think that the stuffy boiling needs a long time, so that the housewives can immediately leave the kitchen and then immediately deal with other urgent matters, once the urgent matters need a long time and need special attention, the housewives forgetfully ignore the stuffy boiling food materials in the kitchen, and the fire accident caused by the fact that the snail is completely dried is a big trouble.

Therefore, how to develop a safety protection with forced shut-off of the supplied gas during use is a technical issue that needs to be solved by the manufacturers.

Disclosure of Invention
