For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of solar boiler comprises support, is parallel at least two vacuum heat collection pipes on the support, is set in metal sleeve in the vacuum heat collection pipe and the water pipe that is communicated with the metal sleeve lower end.The quantity of vacuum heat collection pipe can dispose as required.

Said vacuum heat collection pipe blind end upwards is provided with, and is fixedly connected and is provided with spillway hole between its openend and the said metal sleeve.

Said metal sleeve upper end is provided with osculum.

Said water pipe two ends are provided with valve.

Said water pipe is a metal tube, metal sleeve lower end and the welding of said water inlet pipe.

Said water pipe is a pvc pipe, is threaded by threeway between metal sleeve lower end and the water pipe.

Said metal sleeve is a kind of in stainless steel tube, aluminum pipe or the copper pipe.

Said water pipe water side is connected with storage tank.

Adopt the beneficial effect that technique scheme produced to be: vacuum heat collection pipe is adopted the openend structure of setting downwards, and suit to adopt the higher metal metal sleeve of heat transfer efficiency in vacuum heat collection pipe, the interior directly process water pipe output of water of metal sleeve through heating; Also can flow in the insulation water butt; Because in heating process, the heat of every vacuum heat collection pipe absorption only is used for heating jacket and is contained in the water in its inner metal sleeve, it is few to add the hot water amount; As long as it is fine; Just can the water in the metal sleeve is boiled in the several hrs, reach the level of drinking, simultaneously; Stainless steel tube, copper pipe or aluminum pipe are promoted in the drinking water field, and the water that from metal sleeve, flows out directly can be drunk.
