Abstract

An automatic safety gas hose comprises a hose body part and a protector part connected each other. The hose body part consists of inner and outer tube walls and a gas-filled layer between the inner and outer tube walls. The protector part includes a tube body, a gas bag, a sealed cap, a cap rod, a spacing piece, front and back pressure springs and a slider. The gas bag is in communication with the gas-filled layer. The front and back pressure springs are mounted on the cap rod. The sealed cap is fixed at the front end of the cap rod and is supported on the front pressure spring and the back end of the cap rod is connected with the slider top-pressed on the gas bag. The sealed cap is fitted with the sealing face of the tube body.

Description

Technical field [0001] The invention relates to a gas automatic safety hose. Background technique [0002] At present, the popularity rate of household gas use in our country is getting higher and higher. While gas brings many conveniences to people, it also endangers people's life and property safety at all times. Now, gas leakage, poisoning, fire, explosion, etc. are caused by the use of gas. Various safety accidents are also increasing day by day. Although there are some security products developed for the safety of hoses on the market, these products all have defects that cannot be ignored: some have introduced electromagnetic valves in the structure, and their structures are complicated and impractical. Once there is no electricity, all security functions will be lost; some will only call the police and will not automatically cut off the gas source when an air leakage accident occurs. No. 00234322.3 Chinese patent provides a kind of " automatic safety gas hose ", and ...
