Detailed description of the invention

Below in conjunction with embodiment, the utility model is conducted further description.

A kind of steam generator, it comprises an outside framework 1, the surrounding of outside framework 1 is closed by side plate 2, outside framework 1 is rectangle weld holder, outside framework 1 internal fixtion has a cylindric water tank 3, water tank 3 top is air exhauster 31, and the bottom of water tank 3 is heater 4, and the side of heater 4 is provided with natural gas input pipe 41; On water tank 3, the bottom of water tank 3 is processed with multiple circular hole 35, the inner each circular hole 35 of water tank 3 is welded with the heating tube 33 of a curved design, heating tube 33 extends to water tank 3 top always, multiple heating tube 33 converges to one at water tank 3 top and extends in smoke evacuation room 34, and smoke evacuation top, room 34 is air exhauster 31; The top of described water tank 3, near air exhauster 31 is steam output pipe 32, and steam output pipe 32 and water tank 3 inside communicate; Described water tank 3 side, a bending tube connector 63 extends out in side, water tank 3 top, extend in communication chamber 6, the bottom of communication chamber 6 is connected to one by the sidewall of a tube connector 63 equally and bottom water tank 3, form a communication apparatus, tube connector 63 extends to below water tank 3, and its end is provided with a valve 64, the sidewall of communication chamber 6 is provided with a water filling port 65, in communication chamber 6, is provided with a pressure sensor 62 and a level sensor 61; It is a controller 5 immediately below communication chamber 6, described controller 5 is connected with pressure sensor 62 and level sensor 61 by wire, on described outside framework 1, a master switch 22 and a heater knob 21 is provided with bottom it, described master switch 22 is connected with controller 5 by wire with heater knob 21, and its effect is firepower size when controlling the utility model switch and heating.
