[0022] As Figure 1 、 2 shown, there are two sets of explosion-proof water pumps 6 and explosion-proof electric controllers 7 respectively. Another set of explosion-proof water pump 6 and explosion-proof electric controller 7 are connected in parallel on the explosion-proof pipeline. One set is in normal use and the other set is for backup. A switching valve is arranged on the explosion-proof pipeline. When the explosion-proof water pump 6 in use has problems, the switching valve is used to switch to the other set of backup explosion-proof water pump and explosion-proof electric controller 7.

[0023] As Figure 4 、 5 shown, the explosion-proof electric water tank 5 includes a water tank cylinder body 51, an electric heating core 52, a connecting flange 53 and a water tank end cover 54.
