Two-part, wall-mountable electrochemical dispenser
First Claim
1. A liquid emitter combination comprising:
- a reusable gas generator subassembly for generating gaseous material;
a disposable liquid emitter subassembly associated with said gas generator such that emission of said gaseous material by said gas generator subassembly will cause said disposable liquid emitter subassembly to emit liquid contained within a liquid chamber formed therein, said disposable liquid emitter subassembly comprising a housing separated into two individual chambers by a pliable sheet passing therethrough, wherein one said individual chamber is said liquid chamber; and
an absorbant pad wrapped about a portion of said disposable liquid emitter subassembly whereby said pad is in spaced relation to outer walls defining said housing.

Abstract
A Two-part, Wall-mountable Electrochemical Dispenser. The dispenser assembly consists of a disposable fluid storage reservoir and a non-disposable dispenser. The dispenser holds an electrochemical gas generator, its associated electronics, and a power source. The generator can be set for fluid delivery rates of between 1 mL/day and 50 mL/day. The system has a battery-determined operational life of about 2 years, assuming rates of up to 2 mL/day and 2 C-size batteries. The fluid storage reservoir is formed by two plastic shells separated by a plastic diaphragm. Gas produced by the generator acts on the diaphragm thereby displacing fluid that is then captured by an evaporation pad from which it can readily emanate into the environment. The reservoir can be removed and discarded after depletion of the liquid, and then replaced by another filled assembly. As needed, the refill holds an anti-theft coded card that prohibits the re-use of the refill.

10. An evaporative dispenser device, comprising:
-
a reusable gas generator subassembly for generating gaseous material; and a disposable liquid emitter subassembly associated with said gas generator such that emission of said gaseous material by said gas generator subassembly will cause said disposable liquid emitter subassembly to emit liquid onto an absorbent pad for evaporation into the environment surrounding said dispenser device, said liquid contained within a liquid chamber formed within said liquid emitter subassembly, said disposable liquid emitter subassembly comprising a housing separated into two individual chambers by a pliable sheet passing therethrough, one said individual chamber being said liquid chamber, said housing further comprising a plurality of prongs extending therefrom to which said absorbant pad is attached, whereby said absorbant pad is in spaced relation to outer walls of said housing.
