The last main water pipeline 501 is connected to the steam outlet 7.

[0029] When the instant steam generator provided above is used, pure water is added to the external or built-in water tank 1, and then the external or built-in water pump 8 and the manual switch 9 are turned on. At this time, the external or built-in water pump 8 pumps the pure water in the external or built-in water tank 1 to the water inlet of the steam heater 2. At this time, the water flow rate can be controlled by a manual or fully automatic electromagnetic flow integrated valve 10, and then the pure water flows along the main water pipe 501 and the auxiliary water pipe 502. During the flow, it is heated by the heating tube 4 to generate steam and discharge it from the steam outlet 7. Since the auxiliary water pipe 502 is spirally wound around the outer surface of the main water pipe 501, the pipe will be extended, thereby extending the flow time and heating time of the water flow and generating sufficient water vapor.

[0030] In this embodiment, a first liquid inlet pipe 101 is installed at the water outlet end of the external or built-in water tank 1, the other end of the first liquid inlet pipe 101 is connected to the input end of the external or built-in water pump 8, the output end of the external or built-in water pump 8 is connected to the second liquid inlet pipe 102, the other end of the second liquid inlet pipe 102 is connected to the manual switch 9, the other end of the manual switch 9 is connected to the third liquid inlet pipe 103, the other end of the third liquid inlet pipe 103 is connected to the manual or fully automatic electromagnetic flow integrated valve 10, the other end of the manual or fully automatic electromagnetic flow integrated valve 10 is connected to the fourth liquid inlet pipe 104, and the other end of the fourth liquid inlet pipe 104 is connected to the water inlet 6.

[0034] In this embodiment, the diameter of the main water channel pipe 501 is greater than the diameter of the auxiliary water channel pipe 502 .

[0035] Such a configuration is beneficial for the auxiliary waterway pipe 502 to fully contact the outer surface of the main waterway pipe 501 .

[0036] In this embodiment, the auxiliary water channel pipe 502 is spirally wound on the outer surface of the main water channel pipe 501 .

[0037] The auxiliary water pipe 502 arranged in this way can be spirally wrapped around the outer surface of the main water pipe 501 for multiple turns, and then connected to the adjacent auxiliary water pipe 502, thereby ensuring that the pipe length is extended to the maximum extent around the outer surface of the main water pipe 501.

[0039] The main water pipe 501 and the auxiliary water pipe 502 arranged in this way have a fast heating speed, a small water volume, and reduce the risk of pressure in the pipe, making it safer to use.

[0040] In this embodiment, the housing 3 is made of cast iron, cast aluminum or high temperature resistant material, and a connecting piece 11 for fixing the housing 3 is fixedly connected to the housing 3 .

[0041] In this way, the number of the connecting members 11 can be four, and the four connecting members 11 are respectively installed at the four corners of the shell 3, so as to facilitate the fixed connection of the shell 3.

[0042] In this embodiment, a temperature sensor is disposed inside or outside the housing 3 , and the temperature sensor is used to detect the temperature inside or outside the housing 3 .

[0044] The technical solution provided by the utility model is as follows: Figure 1-5 As shown, when in use, pure water is added to the external or built-in water tank 1, and then the external or built-in water pump 8 and the manual switch 9 are turned on. At this time, the external or built-in water pump 8 pumps the pure water in the external or built-in water tank 1 to the water inlet of the steam heater 2. At this time, the water flow can be controlled by a manual or fully automatic electromagnetic flow integrated valve 10, and then the pure water flows along the main water pipe 501 and the auxiliary water pipe 502. During the flow, it is heated by the heating tube 4 to generate steam and discharged from the steam outlet 7. Since the auxiliary water pipe 502 is spirally wound on the outer surface of the main water pipe 501, the pipe will be extended, thereby extending the flow time and heating time of the water flow, thereby generating sufficient water vapor.
