Automatic heating water pipe in cold weather

The utility model relates to the technical field of water pipe anti-freezing, in particular to an automatic heating water pipe in cold weather. A heating mechanism; the heating mechanism is installed outside the water pipe body and used for heating the water pipe body when the water pipe body is at the temperature of zero DEG C or below. The heating mechanism comprises an iron sleeve, and an electromagnetic induction coil is installed on the outer side of the iron sleeve in a sleeving mode. According to the electromagnetic connector, the environment temperature monitor of the electromagnetic connector detects the environment temperature outside the water pipe body, when the temperature outside the water pipe body is zero or below, the electromagnetic induction coil is automatically started, so that the electromagnetic induction coil and the iron sleeve form an electromagnetic field, and the iron sleeve is integrally heated; and the electromagnetic induction coil is used for uniformly heating the iron sleeve,
