Claims

[Scope of utility model registration request]

An ice chamber is provided in a cylindrical casing made of a non-magnetic material, an outflow path is provided on the peripheral wall of the casing, a valve seat with a valve opening is formed at the lower end of the ice chamber, and an inflow path is formed. The provided connecting body is tightly attached in a watertight manner, and a float integrally provided with a flange having a plurality of notches or small holes, an adjuster, and a magnet is placed on the upper part of the valve seat, and a float is placed on the valve opening. A coil spring is interposed between the upper surface of the flange portion and the upper inner wall of the ice chamber to force the adjuster to slide, and further A flow rate switch characterized in that a normally open switch that is turned on and off by the magnetic force of the magnet is provided on a support provided at a predetermined location outside the earthen wall of the casing.
