When installed on the body of the water inlet pipe 2, the water inlet pipe 2 and the scale inhibition device are connected, That is, all or part of the water in the water inlet pipe 2 will flow into the scale inhibitor. The scale inhibitor contained in the accommodating chamber 4 is a granular solid filter material. After being soaked in water, a scale inhibitor is generated, and the saturation concentration of the scale inhibitor in the water is lower than 3 mg/L. The scale inhibitor is installed in the inner tank 1, which does not occupy the external space; the scale inhibition principle that the solid granular scale inhibitor is dissolved to produce the scale inhibition factor to avoid blocking the water inlet pipe 2; at the same time, the solubility of the scale inhibitor is low and saturated Low concentration, long service life, eliminating the trouble of frequently replacing or adding scale inhibitors. The anti-scaling device is arranged on the water inlet pipe 2, and all/part of the water flowing out of the water inlet pipe 2 is heated after being heated by the anti-scaling device to reduce or even not produce scale.
