Abstract

A hand-held spray apparatus is provided, which includes a tank for holding a supply of liquid to be treated and a functional generator carried by the hand-held spray apparatus. The functional generator receives the liquid from the tank and has an anode chamber and a cathode chamber separated by an ion exchange membrane and electrochemically activates the liquid that is passed through the functional generator. A spray output is coupled to an output of the functional generator and dispenses the electrochemically activated liquid as an output spray.

Claims

1. A hand-held spray bottle comprising:

a tank for holding a supply of liquid to be treated;

a functional generator carried by the hand-held spray bottle, which receives the liquid from the tank and comprises an anode chamber and a cathode chamber separated by an ion exchange membrane and which electrochemically activates the liquid that is passed through the functional generator to produce an anolyte liquid in the anode chamber and a catholyte liquid in the cathode chamber;

a flow path, which combines an entire flow of the anolyte liquid produced from the anode chamber with an entire flow of the catholyte liquid produced from the cathode chamber to form a blended anolyte and catholyte liquid along a single path, without separate storage of the anolyte liquid or catholyte liquid along the flow path, downstream of the functional generator;

a spray output, which is coupled to the flow path and dispenses the blended anolyte and catholyte liquid as an output spray; and

a pump, which is coupled to the flow path and configured to pump the liquid from the tank, through the functional generator and out the spray output.

2. The hand-held spray bottle of claim 1, wherein the bottle comprises a hand-triggered spray bottle.

3. The hand-held spray bottle of claim 2, wherein the spray bottle forms the tank for holding the liquid.

4. The hand-held spray bottle of claim 1, and further comprising:

an output flow tube, which is coupled between the functional generator and the spray output, wherein the pump and the output flow tube are configured to dispense the blended anolyte and catholyte liquid through the spray output within 5 seconds of the time at which the anolyte and catholyte liquids are produced by the functional generator.

5. The hand-held spray bottle of claim 4, wherein the pump and the output flow tube are configured to dispense the blended anolyte and catholyte liquid through the spray output within 3 seconds of the time at which the anolyte and catholyte liquids are produced by the functional generator.

6. The hand-held spray bottle of claim 1, wherein the functional generator is powered by at least one battery carried by the hand-held spray bottle.

7. A method comprising:

containing a supply of liquid to be treated within a tank of a hand-held spray bottle;

pumping the liquid to be treated through a functional generator carried by the spray bottle;

electrochemically activating the liquid with the functional generator to produce an anolyte liquid in an anode chamber and a catholyte liquid in a cathode chamber of the functional generator, wherein the anode chamber and cathode chamber are separated by an ion exchange membrane;

combining an entire flow of the anolyte liquid with an entire flow of the catholyte liquid to form a blended anolyte and catholyte liquid; and

dispensing substantially all of the blended anolyte and catholyte liquid as an output spray through a spray output of the hand-held spray bottle upon electrochemical activation by the functional generator without storage of the anolyte liquid, catholyte liquid or blended anolyte and catholyte liquid on the spray bottle, downstream of the functional generator.

8. The method of claim 7 wherein the step of dispensing comprises:

dispensing the blended anolyte and catholyte liquid within 5 seconds of the time at which the anolyte and catholyte liquids are produced by the functional generator.

9. The method of claim 7 wherein the step of dispensing comprises:

dispensing the blended anolyte and catholyte liquid within 3 seconds of the time at which the anolyte and catholyte liquids are produced by the functional generator.

10. The method of claim 7 and further comprising powering the functional generator by a battery carried by the hand-held spray bottle.

11. The method of claim 7 wherein the liquid consists solely of tap water.
