Electrolytic water tank

The invention provides an electrolytic water tank. The electrolytic water tank comprises a tank body, a water outlet used for connecting a water draining pipeline is arranged at the lower end of the tank body, the water outlet of the tank body is provided with a water electrolysis device, the water electrolysis device comprises a baseboard, an electrolysis electrode placed on the upper end surfaceof the baseboard and a water tank power supply and water drainage assembly placed at the lower end of the baseboard, the water tank power supply and water drainage assembly is fixedly connected withthe tank body, and the baseboard is detachably connected with the water tank power supply and water drainage assembly. The cooperation of the water electrolysis device with the water outlet allows thewater electrolysis function to be transplanted to a common water tank, so water drainage after cleaning is easy, the application range of electrolytic water cleaning is enlarged, and the electrolyticwater tank has high versati
