WATER STERILISATION APPARATUS

摘要

The invention provides water sterilising apparatus (10) adapted to employ the process of heavy metal sterilisation and including a body (11) defining a chamber (12) formed with spaced inlet and outlet openings (13, 14) whereby water may be caused to flow through the chamber; a silver anode (15) to coact with at least one cathode (16) spacedly mounted in said chamber for release of Ag+ ions to the flow of water therebetween; electric circuit means (17) including power cell means (18) associated with said body and connected to said electrodes (15, 16); an on/off switch (20) in said circuit means (17) normally disposed inoperatively so that the circuit is open when water is not entering said chamber (12) at said inlet opening (13), and a switch-actuating valve assembly (21) mounted movably adjacent said inlet opening, said valve assembly being normally urged in biased manner to a position in which it closes the inlet opening (13) but adapted to be moved against said bias by water caused to flow through said inlet opening whereby said water enters and passes through said chamber and out said outlet opening, and the parts being so made and arranged that movement of said switch-actuating valve assembly (21) to open the inlet opening (13) causes said normally-open switch (20) to be closed to complete the circuit.
