Patent ID: 6951225

Claim:
A switching valve for separately producing alkaline ion water and acid ion water which comprises: a valve housing provided with an inlet; a supply channel for introducing ion water to said valve housing through said inlet, an alkaline ion water discharging channel and an acid ion water discharging channel extending from valve seats provided at opposite sides of the valve housing; a valve body slidably disposed within the valve housing, said valve body being configured to selectively seal either one of the discharge channels by being fixed in one of said valve seats, while the other of said discharge channels remains open; an iron core extending from the valve body into said acid ion water discharging channel, said iron core being movable in a translational manner with said valve body; and a solenoid operatively associated with said acid ion water discharge channel containing said iron core, wherein the opening and closing of the discharge channel is effected by a polarity change of the solenoid, whereby the voltage applied to the solenoid causes the solenoid to exert an electromagnetic force on the iron core which moves the valve body within the valve housing.
