Abstract
The present disclosure provides a system (100) for operating a valve in an apparatus for dispensing heated conductive liquid and, more specifically, for implementing an automated safety shut off mechanism in the valve the moment that the liquid comes into contact with a user's body. The system operates by coupling a sensor (104) to a control element (106) such as a button that operates the liquid dispensing apparatus, and also introducing an electric current into the flow of liquid. When a user holds the button and comes into contact with the flow of heated liquid, the sensor detects the current from the flow and a controller shuts off the valve (108).
Claims14
A system for delivering heated conductive fluid, the system comprising:
- a conduit (112) for delivering a flow of heated conductive fluid;
- a power source (110) configured to deliver an electric current into the flow;
- a valve (108) coupled to the conduit and configured to control the flow;
- a control element (106), the control element being configured to, upon actuation by a conductive body, cause the valve to open until the actuation is ceased;
- at least one sensor (104) coupled to the control element;
- and
- a controller, the controller being (102) configured to:
- receive a reading from the at least one sensor;
- determine that the conductive body has come into contact with the electric current from the power source;
- and
- override the control element and operate the valve to shut off the flow of heated conductive fluid.
