Abstract
A connecting structure of an electric water heater liner and a water outlet pipe comprises the electric water heater liner, a water pipe connector, and the water outlet pipe, wherein the water pipe connector is fixed on the electric water heater liner in a sealing mode, and the water outlet pipe penetrates the water pipe connector and extends into the electric water heater liner. The water outlet pipe is connected with the water pipe connector in a sealing mode. The connecting structure of the electric water heater liner and the water outlet pipe is characterized in that a clamp device is arranged outside the water pipe connector, and the clamp device clamps a sealing joint between the water outlet pipe and the water pipe connector. Preferably, the clamp device is a nut, and outer threads which are connected with the nut are arranged on the outer circumference of the water pipe connector. Or preferably, the clamp device is an annular part, and the inner diameter of the annular part is slightly larger than the outer diameter of the water pipe connector so that interference fit exists between the water outlet pipe and the water pipe connector. Therefore, a sealing connection between the water outlet pipe and the water pipe connector is clamped. The connecting structure of the electric water heater liner and the water outlet pipe has the advantages of effectively reducing water leakage probability of the electric water heater liner and the like.
