Fluid dispenser with UV sanitation

A hand cleaning foam dispenser comprising:

• a reservoir providing a supply of foamable liquid;
• an air compartment providing a supply of air;
• a foam generator that mixes the foamable liquid and the air to produce a foam;
• a liquid pump for delivering the foamable liquid to the foam generator;
• an air pump for delivering the air to the foam generator;
• and
• a wave emitter that emits a wave into the air compartment to sanitize the air compartment;
• wherein the wave emitter comprises an electromagnetic radiation emitter that emits electromagnetic radiation into the air compartment to sanitize the air compartment;
• wherein the air compartment comprises a compartment defining wall;
• wherein the electromagnetic radiation emitter is positioned outside of the air compartment;
• wherein at least a portion of the compartment defining wall is formed from a material that permits the electromagnetic radiation to pass through the compartment defining wall into the air compartment;
• wherein the hand cleaning foam dispenser further comprises a housing and a foam pump, the foam pump comprising the air compartment, the liquid pump, the air pump, and the foam generator;
• wherein the housing is configured to removably receive the foam pump;
• wherein the electromagnetic radiation emitter is arranged on the housing for emitting the electromagnetic radiation through the compartment defining wall into the air compartment when the foam pump is received by the housing;
• wherein the electromagnetic radiation emitter is configured to only emit the electromagnetic radiation when the foam pump is received by the housing;
• wherein the hand cleaning foam dispenser further comprises a switch that is activated when the foam pump is received by the housing;
• wherein the electromagnetic radiation emitter is configured to only emit the electromagnetic radiation when the switch is activated;
• wherein the housing has a lock-out mechanism to prevent unauthorized pumps from being received by the housing;
• wherein the foam pump has a lock-out structure that engages with the lock-out mechanism when the foam pump is received by the housing;
• and
• wherein the switch is located on or adjacent to the lock-out mechanism, so that the lock-out structure activates the switch when the foam pump is received by the housing.
