An intelligent toilet cleaning device, comprising a purifier, a toilet body, a seat ring temperature sensor, a main controller, an auxiliary controller, a cleaning control device, a steam generating device, a water The foam generating device and flip cover module are composed. When the upper cover of the toilet is opened, the normally closed solenoid valve water flow switch and the booster pump are simultaneously activated to energize the water, and the high-pressure water flows through the water nozzle to suck out the foaming liquid from the foaming liquid bottle and mix it with water The water foam formed is sprayed in the toilet bowl, which plays the role of easy flushing of toilet dirt, no smell, and splash prevention. In the toilet, it can realize the function of intelligent buttock washing, women's washing, electric washer nozzle cleaning, and drying fan to dry the buttocks.
