However, there are many passengers on trains and other means of transportation. There are the following problems with using pipeline machines to heat water: 1. The volume of pipeline machines is small, and the amount of water heated at one time is limited, which cannot meet the needs of many passengers; 2. Pipeline machines use heating tanks to heat water, and their heating power is low, and it takes a long time to heat water. Therefore, it is necessary to replace a heating device that compensates for the above defects. Utility Model Content

[0007] By adopting the above technical solution, when heating the water for the train, the water is stored in the heating tube, and the rare earth heating film is energized. Under the action of the electric field, the molecules inside the rare earth heating film vibrate violently and generate heat.

The locking pressure plate is loosened, and the locking pressure plate moves under the force of the spring sheet until the two locking pressure plates fit together. At this time, the connecting ring is located in the clamping groove, thereby limiting the locking bolt, thereby realizing the installation of the support plate and the anti-loosening treatment of the locking bolt.
