AI Technical Summary

Benefits of technology

The patent is about a foam dispensing system that includes an under-counter mount foam dispensing system. The system includes a refill unit that can be easily installed and connected to a source of pressurized air. The refill unit includes a container for holding a foamable liquid, a liquid pump, and an air manifold for releasably connecting to the source of pressurized air. The system also includes an air compressor and a liquid outlet tube for pumping liquid from the container to the mixing chamber. The system can be installed in different configurations, allowing flexibility in the placement of the refill unit. The technical effects of the patent text include the simplified installation process, flexibility in system placement, and improved efficiency of foam dispensing.

Problems solved by technology

These types of dispensers are not desirable because bacteria can grow in the container and contaminate the liquid.
Although these types of refills are more sanitary than refilling the container, these types of refill units are expensive because they contain an air pump and a liquid pump.

Embodiment Construction

[0021]An exemplary embodiment of a foam dispensing system 100 is best described with respect to FIGS. 1-4. FIG. 1 is a cross-section of an exemplary embodiment of a foam dispenser system 100 with a refill unit 140 installed therein. FIG. 2 is a cross-section of the foam dispenser system 100 with refill unit 140 removed. Foam dispenser system 100 includes a spout 106. Spout 106 has a hollow interior 107. Spout 106 is secured to counter 104 by any means such as, for example, a threaded connector (not shown) that extends from spout 106 to below the counter, and the threaded connector is connected to a lower bracket 110. An air pump or air compressor 120 is secured to lower bracket 110 by a mounting member, which is not shown for purposes of clarity. Air compressor 120 is permanently mounted below the countertop 104 and is not removed with refill unit 140. Air compressor 120 includes an actuator 121 (FIG. 2). Actuator 121 is an electric actuator. Actuator 121 may include a direct curren...

Abstract

Under-counter foam dispensing systems and refill units for under-counter mount foam dispensing systems are disclosed herein. An exemplary refill unit includes a container for holding a liquid, at least a portion of a liquid pump, a quick-connect air manifold for releasably connecting to a pressurized air source, an air passage to a mixing chamber and a liquid passage to the mixing chamber. The air inlet is in fluid communication with the source for pressurized air when the refill unit is mounted in the dispensing system and disengages from the pressurized air source when the refill unit is removed from the under-counter mount foam dispensing system.

Description

RELATED APPLICATIONS[0001]This non-provisional utility patent application claims priority to and the benefits of U.S. Provisional Patent Application Ser. No. 61 / 723,468 filed on Nov. 7, 2012, and entitled UNDER-COUNTER MOUNT FOAM DISPENSING SYSTEMS WITH PERMANENT AIR COMPRESSORS AND REFILL UNITS FOR SAME. This application is incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The present invention relates generally to under-counter mount foam dispensing systems, and more particularly to under-counter mount foam dispensing systems with permanently affixed air compressors, and refill units for such foam dispensing systems having an air connection manifold for placing the refill unit in fluid communication with the air compressor.BACKGROUND OF THE INVENTION[0003]Liquid dispenser systems, such as liquid soap and sanitizer dispensers, provide a user with a predetermined amount of liquid upon actuation of the dispenser. In addition, it is sometimes desirable to dispense ...
