Description

Temperature sensing on-off valve for suction pipe Technical Field The utility model belongs to the technical field of drinking appliances, and particularly relates to a temperature-sensing on-off valve for a suction pipe. Background In order to prevent scalding caused by direct sucking of hot water in the drinking cup by the drinking straw by children, an anti-scalding safety structure is generally arranged at present, and an anti-scalding valve is adopted in some technical directions, and the valve mainly utilizes the characteristics of temperature sensing memory alloy, so that the valve can stretch and retract in the change of water temperature. In the scheme shown in CN106913159B splash-proof suction pipe valve and suction pipe and water cup provided with the same, the temperature control clamp is a spring made of memory alloy, and the pipe body is clamped at high temperature to stop water circulation of the pipe body and is loosened at non-high temperature to restore natural conduction of the pipe body, but the structure is limited by the force of shrinkage of the spring and cannot completely block the water flow pipeline of the suction pipe.
