Abstract: PURPOSE:To prevent stains and bad smells, by connecting a water delivery outlet having a suction inlet sucking air at a negative pressure and a crushing face with which the water stream mixed with air is forced to collide, to a water cut-off valve of a flushing water tank of a toilet seat. CONSTITUTION:When a toilet seat is washed and the water level L in a tank 8 gets dam 6, a cut-off valve (feed water valve) 10 is opened and pressurized water (city water) is poured into the tank 8.

The mixture is sprayed from a nozzle plate 18 provided with a fine blowing-out hole 17. And further, the sprayed water is forced to collide with a crushing plate 20 to crush the air bubbles in the mixed water-air stream so as to become finer. And activated water in which the hydrogen bond of weak water molecules is released by a chemical bond, is generated. And sludge and anaerobic bacteria are discomposed by making use of the natural purifying force of the activated water. In this way, stains and bad smells of a toilet seat can be removed.
