[0041] The working principle of the utility model is:

[0042] After the first valve 33 and the second valve 41 are opened, cold water enters the lower chamber 4 of the housing 1 through the cold water pipe 32 and is accumulated in the lower chamber 4. The cold water accumulated in the lower chamber 4 is softened by the plurality of softening resin columns 37, thereby reducing the generation of scale inside the electric heating boiler.

[0043] The softened cold water enters the inner tank 5 through the cold water inlet pipe 17, and then passes through the first flow area 19, the second flow area 20, the third flow area 21, the fourth flow area 22, the fifth flow area 23, the sixth flow area 24, and the seventh flow area 25 in sequence, and then is output from the hot water output pipe 18. When the cold water flows inside the inner tank 5, the first electric heating jacket 28 heats the cold water inside the first flow area 19 and the third flow area 21, the second electric heating jacket 29 heats the cold water inside the third flow area 21 and the fifth flow area 23, and the third electric heating jacket 30 heats the cold water inside the fifth flow area 23. This ensures that the water flow entering the hot water output pipe 18 reaches the specified heating temperature, and then is output to the radiator for heating.

[0044] The heat insulation layer between the outer liner 26 and the inner wall of the upper chamber 3 ensures that the heat generated by the first electric heating jacket 28, the second electric heating jacket 29 and the third electric heating jacket 30 leaks out as little as possible.

[0045] When the heating is completed, close the first valve 33 and the second valve 41, open the drain valve 35, and discharge the water flow mixed with impurities in the lower chamber 4 through the drain pipe 34. When the water flow in the lower chamber 4 is emptied, unscrew all the installation plugs 36 from the installation port, and the installation plugs 36 with the softening resin column 37 are pulled out from the lower chamber 4, and then the softening resin column 37 is removed from the installation plugs 36, and the softening resin column 37 can be processed or replaced to ensure that the softening resin column 37 can achieve a better softening effect again. After the processing is completed, the softening resin column 37 is installed on the installation plug 36, and then the installation plug 36 is screwed to the installation port to complete the maintenance of the softening resin column 37.
