1. sensing temperature changes and the air-valve assembly automatically switched, and it is characterized in that, comprising:

  • One valve member main body, has a containing space, a gas cylinder lock interface, fluid passage, one first opening and one second opening;

    Described gas cylinder lock interface is connected to described containing space, and the side of described containing space is connected with described fluid passage;

    One end of fluid passage connects the first opening, and its side then connects the second opening;

    One handover module, is arranged in the fluid passage of valve member main body, also comprises;

    One switching member, is contained in described fluid passage;

    One first lock bolt, is locked in the first opening;

    Described first lock bolt also has a service aisle and runs through its axle center;

    One end of described service aisle connects the first opening;

    AndOne first elastic element, is arranged between described switching member and described first lock bolt;

    First elastic element is pushed and is switched unit, makes one end of switching member capping fluid passage, and so, gas is from the first opening through after service aisle incoming fluid passage, and switching member barrier gas flow to containing space, and gas then flows out from the second opening;

    One pricker module, is arranged on valve member main body, also comprises;

    One second lock bolt, from the outside of valve member main body, locks in one end of containing space;

    One moving element, is placed in containing space;

    One second elastic element, is placed in containing space, and is arranged between the second lock bolt and moving element;

    One spike member, its front end is placed in containing space, sequentially through the second lock bolt, the second elastic element and moving element, and is fixed on moving element;

    Its rear end is then outside valve member main body;

    One limiting element, is fixed on one end of spike member;

    One guide posts, passes through described limiting element, and one end is fixed on valve member main body;

    Limiting element can slide in guide posts;

    AndOne temperature sensor, its one end is against limiting element, and the other end is against valve member main body;

    The position of limiting element and spike member is subject to the restriction of temperature sensor, and moving element extrudes the second elastic element, makes the second elastic element store potential energy;

    Temperature sensor can break because ambient temperature changes;

    Temperature sensor breaks, the second elastic element release potential energy, and moving element is promoted by the second elastic element, and drives limiting element and spike member simultaneously;

    AndOne gas cylinder, locks in the gas cylinder lock interface of valve member main body, includes pressurized gas, and form a diaphragm seal at the bottleneck of gas cylinder;

    After temperature sensor breaks, the second elastic element release potential energy, moving element is promoted by the second elastic element, and drives spike member to puncture diaphragm seal;

    After diaphragm seal is punctured, pressurized gas in gas cylinder enters containing space from gas cylinder lock interface, and promote switching member and enter fluid passage, switching member extrudes the first elastic element and capping service aisle, and the gas in fluid passage is flowed out from the second opening.
