[0032] like Figures 1-4 As shown, a steam generator includes:

[0033] Water tank 10, the water tank 10 is provided with a receiving cavity 103, and the side of the water tank 10 is provided with a water inlet 105 communicating with the receiving cavity 103;

[0034] Two mounting joints 20 are respectively disposed at both ends of the water tank 10 and communicate with the receiving cavity 103;

[0035] Two heaters are placed horizontally in the receiving cavity and are parallel to each other. One heater is fixedly connected to one mounting joint 20, and the other heater is fixedly connected to the other mounting joint 20.

[0036] A steam cylinder 40 is located at the upper end of the water tank 10 and is connected to the receiving cavity 103. A steam outlet 403 is provided at the upper end of the steam cylinder 40.

[0037] During operation, water enters the receiving cavity 103 through the inlet 105. At this time, the heater installed in the receiving cavity 103 will heat the water in the receiving cavity 103. After the water is heated, it turns into steam and enters the steam cylinder 40 and is discharged from the steam outlet 403.

[0038] This utility model, by placing the heater horizontally and setting the steam cylinder 40 on the upper part of the water tank 10, facilitates the installation and maintenance of the heater by the staff, and reduces the height space occupied by the heater. Thus, it can increase the steam capacity without increasing the overall height of the device, making it suitable for complete equipment, factories or indoor spaces with insufficient height space. In addition, compared to installing the mounting joint 20 at the same end of the water tank 10, which requires increasing the width of the water tank 10 to accommodate two mounting joints 20 with a diameter larger than the heater, setting the mounting joints 20 at both ends of the water tank 10 ensures that the two mounting joints 20 do not interfere with each other, thereby effectively reducing the overall width of the water tank 10.

[0039] Meanwhile, in order to prevent the heater from shaking in the receiving cavity 103 and improve the stability of the heater, in this embodiment, a plurality of fixing plates 104 are arranged at intervals in the receiving cavity 103. The fixing plates 104 have openings for the heater to pass through, and the outer wall of the heater is in contact with the inner wall of the opening.

[0040] In order to prevent the fixing plate 104 from scratching the heater, a rubber pad is provided on the inner wall of the opening in this embodiment, so that the fixing plate 104 and the heater can make soft contact, thereby effectively preventing the fixing plate 104 from scratching or damaging the heater.

[0041] In addition, to enhance the compressive strength of the steam cylinder 40, in this embodiment, the steam cylinder 40 is composed of a cylinder body 401 and a hemispherical cap 402 disposed on the upper end of the cylinder body 401. The steam outlet 403 is disposed on the upper end of the cap 402. The hemispherical cap 402 has strong compressive strength and can effectively reduce the probability of deformation of the steam cylinder 40 during operation.

[0042] Meanwhile, in order to enhance the overall strength of the water tank 10, in this embodiment, the water tank 10 includes a circular tube 101 and a circular tube cover 102 that is hemispherical and disposed at both ends of the circular tube 101. The two circular tube covers 102 are sealed to the circular tube 101, and the two mounting joints 20 are respectively disposed on the two circular tube covers 102. The hemispherical circular tube cover 102 has strong compressive strength and can effectively reduce the probability of the water tank 10 deforming under pressure.

[0043] In order to facilitate the staff to obtain the internal temperature of the steam generator in real time, this embodiment also includes a temperature detector for detecting the temperature inside the steam cylinder 40, and a temperature detection connector 50 for installing the temperature detector is provided at the upper end of the steam cylinder 40.

[0044] In addition, to prevent the water level in the water tank 10 from being too high and to prevent a large amount of water from entering the steam cylinder 40, which would cause the pressure inside the steam generator to be too high, this embodiment also includes a water level detection sensor for detecting the water level in the steam cylinder 40 and the water tank 10. The sides of the steam cylinder 40 and the water tank 10 are also provided with a water level detection connector 60 for installing the water level detection sensor.

[0045] In order to facilitate the discharge of scale and dirt accumulated in the water tank 10, a drain outlet 70 is also provided in this embodiment. The drain outlet 70 is located at the lower end of the water tank 10 and communicates with the receiving cavity 103.

[0046] Meanwhile, to facilitate the connection of the sewage pipe to the sewage outlet 70 by the staff, two support frames 80 are also provided in this embodiment. The two support frames 80 are spaced apart at the lower end of the water tank 10, thereby lifting the water tank 10 to provide space for the installation of the sewage pipe.

[0047] In addition, the side of the steam cylinder 40 is provided with an expansion interface 90 to facilitate the installation of equipment such as negative pressure valves, safety relief valves, pressure gauge interfaces and pressure switches by operators as needed.

[0048] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
