A foam discharging device includes: a storage portion that stores a liquid agent; a foamer mechanism that changes the liquid agent into foam to generate a foam body; and a discharging portion that discharges the foam body. The discharging portion includes a foam passing chamber that allows the foam body to pass, and one or a plurality of ejection-port forming wall portions that extend downward below the foam passing chamber, are formed into a closed-loop shape in plan view, have the inner space communicating with the foam passing chamber, and have the lower edge having an ejection port formed thereon. At least part of the ejection-port forming wall portion has a bottom end portion formed into a shape that has a thickness reduced toward the lower side. The ejection-port forming wall portion and a second portion. The height position of a lower edge of the first portion is higher than the height position of a lower edge of the second portion.

A wobble plate for a sequentially activated multi-diaphragm foam pump includes three or more wings, a wobble plate shaft, and an aperture located in each of the three or more wings. A first wing is configured to have a first distance from first contact surface of a first pump diaphragm. A second wing is configured to have a second distance from a first contact surface on a second pump diaphragm, and a third wing is configured to have substantially the second distance from a first contact surface on a third pump diaphragm.

Various liquid dispensers are disclosed. Certain embodiments include a portable liquid dispenser configured for consumer use in dispensing soap, sanitizer, or ingestible liquids. The dispenser can comprise a housing, a reservoir having an interior configured to store a liquid, a fluid pathway having an opening in fluid communication with the interior of the reservoir, a pump comprising a plurality of rollers, each of the plurality of rollers being configured to contact a portion of the fluid pathway in a flexible tube such that each of the plurality of rollers compresses a portion of the flexible tube that is in contact with the roller, a nozzle, a fluid damper in communication with the pump and the nozzle, an electronic control unit in electrical communication with the pump, and a rotation-tracking feedback system in electrical communication with the electronic control unit.

A method of filling a fluid dispenser is provided and a method for operating power driven pump in a dispenser is provided.

A “smart-faucet” is provided that provides instructions and feedback to a user that improves the efficacy of a handwashing event. The faucet includes a supply of sanitizer that includes a visualization component, such as a fluorescent component, that assists the user in determining sanitizing coverage of the hands. The visualization component may require the presence of an energy source radiating a specific frequency, such as UV, in order to become visible. The faucet may further be able to communicate information to a remote location regarding supply data necessary to insure just in time delivery of a replacement supply of sanitizer.

Provided is a touchless dispenser including a body, a motor housing coupled to the body, a control assembly including a control board, a motor communicatively coupled to the control board, a cam coupled to the motor, an actuator driven between first and second positions by movement of the cam, and a sensor communicatively coupled to the control board, a reservoir coupled to the body for holding fluid, and a tube assembly having an inlet coupled to the reservoir to receive fluid from the reservoir and an outlet positioned forward of the sensor. The sensor can sense a presence of a user, which is communicated to the control board to cause the actuator to be driven from the first position to the second position to contact the tube assembly to dispense fluid in the tube assembly to the user.

A water dispenser assembly for a hand washing station includes a water heater having a water tank and a heating element configured to heat water contained in the water tank, the water tank having an inlet conduit connected to a water source and an outlet conduit, a water outlet connected to the outlet conduit and configured to receive water from the water heater through the outlet conduit, and a valve in fluid communication with the water heater and configured to selectively permit the water to be forced from the water tank and through the water outlet to dispense the water. The hand washing station may include a computer device configured for controlling components of the station.

A faucet having an integrated dispensing device is provided. The faucet includes a center shaft centered on an axis, a handle portion extending away from the center shaft at a first angle and coupled to the center shaft, and a dispensing device rotatably coupled to the center shaft about the axis. The dispensing device includes a dispensing body and a dispensing arm. The dispensing body defines a first end proximate to the handle portion and a second end opposite the first end. The dispensing arm is coupled with the dispensing body and extends away from the dispensing body at a second angle, the second angle being the same as the first angle.

Disclosed embodiments provide a unique touchless combination device that provides simultaneous convenient use of three features, such as dispensing of liquid sanitizer, access to paper tissues, and a compartment for immediate and safe disposal of used tissues. Touchless operation is provided by use of several proximity sensors which allow to access and use all features of the device without need to touch any part of it. Disclosed embodiments also utilize UV LED lights for the purpose of disinfecting used and disposed tissues.

A fluid dispenser having a temperature sensor that senses a temperature of an external surface presented by a user's hand, and a pump mechanism that is configured to dispense fluid onto the user's hand when the pump mechanism is activated. It is determined whether the fluid has been dispensed onto the user's hand based, at least in part, on the temperature of the external surface presented by the user's hand.
