[0017] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings. The utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0018] Example 1

[0019] like Figures 1 to 3As shown, an expansion kettle of the utility model comprises a kettle body 1, a liquid inlet 3 is provided on the side surface of the kettle body 1, a liquid outlet 2 is provided on the bottom surface of the kettle body 1, a mounting bracket 4 is provided on the side surface of the kettle body 1, the mounting bracket 4 is fixedly slidably connected to the crossbeam 10, the kettle body 1 is provided with a safety valve 13, and an exhaust pipe 5 is provided on the safety valve 13;

[0020] The mounting bracket 4 and the crossbeam 10 are mounted in a slide rail manner. The mounting bracket 4 is provided with a latch hole 8. The latch hole 8 can limit the horizontal movement of the kettle body 1 through the crossbeam 10 and the latch 9.

[0021] An exhaust pipe outlet 12 of the exhaust pipe 5 faces the crossbeam 10 and is away from the safety valve 13 .

[0022] In the present embodiment, when in use, the position of the mounting bracket 4 on the cross beam 10 is adjusted as needed, and the position of the kettle body 1 is further adjusted. After the adjustment is completed, the mounting bracket 4 is fixed by the pin 9 in cooperation with the pin hole 8 and the cross beam 10, thereby fixing the kettle body 1. Thereafter, water can be injected through the liquid inlet 3, and water can be discharged and replaced through the liquid outlet 2. When the internal pressure of the kettle body 1 rises and exceeds the pressure relief value of the safety valve 13 or due to other reasons, the liquid in the kettle body 1 overflows from the kettle body 1 through the exhaust pipe 5. The overflowed liquid will flow toward the cross beam 10 rather than the direction in which the filling staff is standing, thereby avoiding possible scalding and contamination of the staff. In addition, since the exhaust pipe outlet 12 is far away from the kettle body 1, possible liquid residue in the flat groove of the kettle body 1 is avoided, thereby improving the safety and comfort of the vehicle users.
