Exemplary foam-at-a-distance systems include a spout, a container, and a foam generator having a suck-back mechanism located within the spout. The system includes a liquid pump chamber, an air pump chamber, a liquid conduit and an air conduit. The foam generator has a differential bore housing. The differential bore housing has a first portion with a first inside bore and a second portion with a second inside bore, wherein the first inside bore has a smaller diameter than the second inside bore. A piston having a seal extending from the piston that is in contact with the second inside bore is also included. A mixing chamber is located in the large bore. Movement of the seal in an upstream direction provides negative pressure in the second mixing chamber and draws in fluid from the outlet.

A countertop foam dispenser has a spout made of a spout extension front housing and a spout extension rear housing. The spout includes a spout nozzle with a spout opening. A spout mounting shaft is mounted to the spout at a mounting shaft bracket. A mixer pump housing has a spout retainer latch. The mixer pump housing houses a mixer pump. The mixer pump includes a motor. A retainer notch is formed on the lower portion of the spout. The retainer notch is configured to engage the spout retainer latch. A bottle contains liquid soap. The bottle has a connection to the mixer pump housing.

A system for monitoring flush valves includes a plurality of flush valves arranged in at least one restroom, each flush valve including a communication device configured to transmit flush valve data, and at least one controller arranged in a first flush valve and in communication with each other flush valve. The at least one controller is configured to determine a static pressure within the first flush valve, detect a second pressure within the first flush valve, determine that the second pressure is less than the static pressure, in response to determining that the second pressure is less than the static pressure, compare the second pressure with at least one other pressure associated with at least one other flush valve, and determine that the first flush valve is in need of servicing or replacement based on comparing the second pressure with the at least one other pressure.

The present invention relates to dispensers for dispensing moisture-sensitive pods and methods of use therewith, and especially dispensers and methods for dispensing moisture-sensitive pods comprising personal care formulations.

A liquid foam delivery device includes a pump proper, a linear transmission mechanism, a unidirectional input/output gas mechanism and a unidirectional input/output liquid mechanism. The pump proper has a rotating shaft. The linear transmission mechanism converts rotational motion output by the rotating shaft into linear reciprocating motion perpendicular to the rotating shaft. The unidirectional input/output gas mechanism admits gas into a gas inlet and discharge gas from a gas outlet in a direction perpendicular to the rotating shaft through the linear reciprocating motion of the linear transmission mechanism. The unidirectional input/output liquid mechanism delivers liquid admitted through a liquid inlet to a liquid outlet through the rotational motion output by the rotating shaft. The liquid foam delivery device delivers gas and liquid with only one pump proper and one rotating shaft to therefore minimize the required number of constituent components, achieve miniaturization, render assembly easy and cut cost.
