For example, long-distance drivers, RV travelers, or camping enthusiasts need to stay or stay for a long time on the road due to the nature of their work or lifestyle, and traditional bathing facilities cannot meet their needs. Therefore, as a convenient hot water supply device, a car water heater can be easily installed on the vehicle, and the vehicle's power or gas system provides energy to heat the water to a temperature suitable for bathing, thereby providing a convenient, fast, and comfortable bathing solution for these people. By using a car water heater, they can take a shower at any place and any time, maintain personal hygiene, relieve travel fatigue, and improve the quality of life.

[0003] Common car water heaters on the market are usually equipped with a water tank for storing water for users to use. However, because the water is stored in the water tank for a long time, when the ambient temperature is low, the water inside the water tank is prone to freezing, resulting in the water tank being unable to supply water normally. At the same time, the inside of the water tank is prone to freezing and damage due to the freezing of the water, and the maintenance cost is high.

[0004] The utility model is proposed in view of the deficiencies in the prior art. Utility Model Content

[0005] In view of the above-mentioned problem that the water tank in the existing vehicle-mounted water heater stores water for a long time, when the ambient temperature of the water tank is low, the water inside the water tank is easy to freeze, resulting in the water tank being unable to supply water normally. At the same time, the water inside the water tank is easy to be frozen and damaged due to the freezing of the water source, and the maintenance cost is high, the technical solution adopted by the utility model to solve the technical problem is:

This effectively solves the problem that when the water tank in the existing vehicle-mounted water heater stores water source for a long time, the water source inside the water tank is easy to freeze when the ambient temperature of the water tank is low, resulting in the water tank being unable to supply water normally. At the same time, the inside of the water tank is easy to be frozen and damaged due to the freezing of the water source, and the maintenance cost is high.

A water outlet pipe is provided on the installation space and connected to the water outlet end 212, so as to maximize the use of space and effectively improve the space utilization rate inside the device.

[0067] Furthermore, the cross section of the connecting mechanism 4 is rectangular, and the rectangular cross section has a larger edge length, which can evenly disperse the force borne by the connecting components, reduce the situation of local excessive force, and effectively improve the bearing capacity of the connecting structure.
