Description

Technical Field

[0001] The utility model relates to a connecting gas pipe structure for an intelligent gas stove. Background Art

[0002] The connecting gas pipe is an indispensable component for using a gas stove. One end of the connecting gas pipe is used to connect to the front valve or pressure reducing valve of the gas stove, and the other end is connected to the stainless steel connecting gas pipe of the gas supply to transport the gas in the stainless steel connecting gas pipe to the gas stove for use.

[0003] The existing connecting gas pipe is a stainless steel bellows, which plays the role of transmitting gas. It cannot control the opening or closing of the pipeline according to whether the gas stove is ignited or turned off. This connecting gas pipe with a single gas transmission function lacks safety. When the gas stove is turned off due to various factors, the connecting gas pipe cannot control the gas pipe to be closed, causing the gas pipe to continue to supply gas to the gas stove. In the existing intelligent gas stove, the ignition device is built with a solenoid valve to avoid the problem of gas supply when the flame is turned off. If the solenoid valve in the ignition device fails or the connecting gas pipe and the joint are damaged, the entire gas stove does not have another structure that can block the gas output. For this reason, further improvements need to be made to the existing connecting gas pipe. Utility Model Content
