Overflow and overheat shutoff safety gas inlet

An overflow and overheat shutoff safety gas inlet connector, comprising:

• a gas inlet connector, to be connected to the gas source, with a gas inlet hole configured axially, a chamber configured on one end to be connected to the gas inlet hole, and a plurality of holding compartments configured on one side of the chamber;
• a connecting tube, in threaded connection with the gas inlet connector, with a convex portion configured on its one end, a transfer canal configured axially and going through the convex portion, the transfer canal matching the gas inlet hole;
• a first magnetic piece, made of a magnetic material, configured with a plurality of vents, movably configured inside the chamber and matching the gas inlet hole and the transfer canal, the vents being staggered with the transfer canal;
• the transfer canal can be sealed when the first magnetic piece is pressed against the convex portion;
• a plurality of second magnetic pieces, made of a magnetic material, movably configured inside the holding compartments to attract the first magnetic piece, so that the first magnetic piece can be pressed against the opening of the holding compartments;
• and
• a plurality of temperature control pieces, made of a material that can be softened or melted at a preset temperature, configured on one side of the second magnetic piece, so that the second magnetic piece can be fixed inside the holding compartments;
• when the temperature control pieces are softened or melted, the second magnetic pieces can immediately fall apart from the holding compartments.
