When the water flow in the water inlet passage 1221 continues to apply an acting force to the sealing element 131 and the sealing element 131 is completely moved to the first position, the sealing element 131 seals the water outlet 1211, and the water flow does not enter the scale inhibitor accommodating cavity 121 any more; when the opened switch valve core 15 is completely closed, the water pressure in the water flow channel 122 is reduced, the elastic force of the elastic member 132 is greater than the acting force of the water flow on the sealing member 131, at this time, the sealing member 131 moves from the first position to the second position under the elastic force of the elastic member 132, the sealing member 131 is separated from the water outlet 1211, the water outlet 1211 is opened, and since the concentration of the scale inhibition liquid in the scale inhibitor cavity is greater than that of the water in the water flow channel 122, the scale inhibition liquid can be diffused into the whole water flow channel 122, the switch valve core 14 and the water mixing (constant temperature) valve core 15, thereby achieving the purposes of scale inhibition and scale removal. When the sealing member 131 moves to the first position, the sealing member 131 closes the water outflow inlet 1211, and at this time, the water flow in the water inlet passage 1221 cannot continuously flow into the scale inhibitor accommodating chamber 121, so that the scale inhibiting liquid in the scale inhibitor accommodating chamber 121 is prevented from flowing out along with the water flow, and the scale inhibiting duration can be prolonged.
