The boiler body 3 is sealed and stores water and is provided with a steam outlet 11. The steam outlet 11 of the boiler body 3 is connected to terminals through the use of pipelines.

(7) In the air energy boiler, the output end of the rotating unit rotates and drives the rotation of the bulge on the crankshaft; the bulge drives the driving piston to slide in the air cavity via the wrist pin; then air is delivered to the first cavity; the sliding of the driving piston in the air cavity makes the air in the first cavity compressed and generate heat; the heated air enters the heating tubes, heats water in the boiler body and evaporates the water into steam; and the steam is discharged to various terminals through the use of pipelines.

(8) The air energy boiler can quickly reach the required temperature by using air as the heating energy source, and there are no conditional restrictions on its installation. Moreover, there is no electric shock risk since it does not have any electrical element that directly contacts with water.
