A water pump 24 is installed at one end of the water conduit 34 connected to the water conduction water tank 23. The battery 22, the control panel 21 and the heating device 33 are electrically connected.

[0041] A condensing device 4 is provided on the side wall of the dining car body 1 , and the condensing device 4 is connected to the heat conduction water tank 23 and the heat preservation chamber 3 .

[0042] Among them, refer to Figure 1-Figure 3 The dining cart is a common cart structure on the market, including a dining cart body 1, a universal wheel arranged at the bottom of the dining cart body 1, a push rod installed on the side of the dining cart body 1, and a detachable shelter installed on the top of the dining cart body 1. The dining cart body 1 is made of metal material, and the shape of the dining cart body 1 is a rectangular structure, and the control chamber 2 and the heat preservation chamber 3 are arranged at intervals in the vertical direction inside;

[0043] Reference Figure 4-Figure 5 The control chamber 2 is mainly used to install the battery 22, the control panel 21 and the heat-conducting water tank 23.
