CONTROL INTERFACE FOR ELECTRONIC FLUID CONTROL VALVE

摘要

An electronic interface (36) for use in the control of fluid delivery through a hand-held device. Push-button switches (16) or similar devices (37a, b, c and d) of the electronic interface are located on a hand-held portion of a fluid delivery device (30) and provide switching input to a microprocessor (10). The switches can control the temperature, volume, and/or composition of the fluid through the device such as a shower rose or a sprayer. The effect of any adjustment of the switches may be indicated by a bi-colour light emitting diode (LED) (37e). One or more electronic fluid control valves may be located distant from the interface and the interface may communicate with the valves through the use of a communication link (e.g. four-wire bus (13)) imbedded in the hose, or a wireless system using infrared, radio or optical techniques.
