The steel wire separates the space to provide a transfer space for the waste heat from the exhaust port of the compressor, thereby improving the heat transfer efficiency; at the same time, the spiral winding design of the steel wire ensures uniform heat transfer and smooth heat transfer.
[0007] Further, the ports of the self-heating pipe are elliptical. The elliptical design of the ports of the self-heating pipe ensures the flow space of the airflow, and at the same time, increases the contact area with the air valve connector to ensure the air tightness.

The air flow guide protrusions guide the airflow to prevent excessive air pressure from affecting the air tightness between the self-heating pipe and the water pipe.
[0009] Further, the waterway pipe is provided with an interface at both ends; the interface is a horn type. The horn type interface can reduce the turbulence and vortex when the water flow enters, thereby improving the overall stability of the system.
[0010] Further, the waterway joint is provided with a clamping platform inside the end close to the waterway pipe; the interface and the clamping platform cooperate to complete the installation, provide a high-strength connection, and ensure the stability of the pipeline system; the interface and the clamping platform cooperate to have good sealing performance, can maintain good sealing effect under high pressure and high flow conditions, thereby avoiding leakage.
