Or, the bottom surface of the second chamber 350 is obliquely arranged, and a plurality of fifth communication holes are further arranged on the side surface of the second chamber 350, and the size of the fifth communication holes is smaller than that of the scale inhibitor; the side surface of the second chamber 350 far from the water inlet pipe 200 extends downward to be connected with the bottom surface of the inner container 100, the bottom surface of the accommodating chamber is inclined from the side surface close to the water inlet pipe 200 to the side surface far from the water inlet pipe 200 to form an inclined surface with a certain radian, and the fifth communication hole is arranged on the side surface far from the water inlet pipe 200.

Preferably, two second chambers 350 are provided, and the two second chambers 350 are disposed on the baffle plates at both sides of the inlet pipe 200.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
