Description

Timing flameout protection gas valve structure

The present invention relates to a flame-out protection gas valve structure; in particular, it relates to a time-out flame protection gas valve structure that can forcibly shut off the supply gas in use at a fixed time.

According to the conventional gas stove gas valve structure, it mainly includes: a furnace head with an inner and outer ring furnace tube, a communicating gas valve set at the inner and outer ring furnace tubes of the furnace head, and a set of The supply of total gas at the gas valve, where the gas valve includes an intake passage for supplying the inflow of total gas, a gas chamber connected to the intake passage and used for a closed housing, and Connected to the gas chamber and used as a gas outlet channel for the split gas that has flowed through the closure to flow out toward the outside of the gas valve;

When in use, the rotary knob will turn to drive the closure to follow the rotation, so that the gas chamber can be connected to the outlet channel. At this time, the total supply gas will flow through the inlet channel and the gas in sequence. The chamber, the closure and the gas outlet channel then flow into the inner and outer ring furnace tube, so that the inner and outer ring furnace surface of the furnace head is provided with a supply of split gas, thereby achieving the purpose of ignition and combustion.

Although the above-mentioned creation project can achieve the original creation purpose, it is highly praised by the industry and general operators. However, in view of the rapid development of technology in the industry and spare no effort, the applicant has made further efforts to research and improve It is perfect and practical; and recently, creators have gone through countless updates of experimental tests and summarized consumers’ actual operations. In response to the use of comments, it was found that the following problems still need to be further improved:

Since ordinary housewives will switch the fire to a low fire before simmering when simmering, at this time, if there is an urgent need to deal with urgent matters, they will subjectively think that simmering is a longer cost. Time, so that you can leave the kitchen immediately and then rush to handle other urgent matters. Once the urgent matters take a long time and require concentration, they tend to ignore the stuffy ingredients in the kitchen due to forgetfulness. The accidental fire accident caused by the stuffy pan being completely dried is a big trouble.

Therefore, how to develop a safety protection that can forcibly shut down the gas supply during use is a technical issue that the industry needs to solve first.
