Abstract: Exemplary embodiments of energy efficient foam pumps and dispensers are disclosed herein. An exemplary foam dispenser included a housing, a reservoir for holding a foamable liquid, a motor, a motor shaft, and a turbine air pump. The turbine air pump is connected to the motor shaft. A cam is also attached to the motor shaft and is used for driving a liquid pump. Liquid from the liquid pump and air from the turbine air pump are mixed in a mixing chamber and dispensed through an outlet nozzle. The touch-free foam dispenser further includes a sensor for sensing an object, circuitry for receiving a signal from the sensor indicative of an object being present and circuitry for energizing the motor to dispense fluid in the form of a foam.

Abstract: A fluid dispenser with a fluid pump for dispensing fluid on movement of an actuator, and an air pump for delivering a stream of air through at least one sound generator on movement of the actuator. The sound generator produces at least two sounds as the actuator is moved from a first position to a second position, with each sound produced in a different time period during a cycle of operation, or differing from the other sound in respect of one or more detectable sound characteristics, such as duration, frequency, temporal alignment, amplitude, and/or timbre. The time period of each sound is a function of the relative location of the actuator between the first and second positions.

Abstract: A dispensing device for dispensing a foamable product. The dispensing device comprises a dispensing channel (110; 210; 410). The dispensing channel has: an inlet (111; 211; 411) for communicating with a valve-element (120) of a container (130) containing the foamable product; and an outlet (112; 212; 412) for dispensing the foamable product. The dispensing channel (110; 210; 410) further comprises a variable-volume cavity (140; 240; 440) at the outlet. The variable-volume cavity (140; 240; 440) is defined at least partly by a first component (142; 242; 442) and a second component (144; 244; 444) that is separate from and rigidly movably with respect to the first component to vary the volume of the variable-volume cavity (140; 240; 440) between a first configuration and a second configuration. In the first configuration, the variable-volume cavity (140; 240; 440) has a first volume and the outlet (112; 212; 412) is closed. In the second configuration, the variable-volume cavity has a second volume and the outlet (112; 212; 412) is open. The second volume is greater than the first volume.

Abstract: A spring foam pump and a packaging container including the same are provided. Under the push of the pressing head (2), the liquid pump piston (71) and the air pump piston (72) force the fluid and gas in the liquid pump chamber (5) and the air pump chamber (6) to enter the gas-liquid mixing chamber (4) to form foam, respectively. Under the action of pressure, the foam flows out after passing through the foam channel (21). The sealing requirement is not very high, and it can be used in various environments. The packaging container comprises a container capable of containing fluid and the spring foam pump.

Abstract: A fluid dispenser includes a housing, a pump, an outlet nozzle, a reservoir, a liquid passage, an air passage, and a refill container. The pump and reservoir are attached to the housing, and both the outlet nozzle and the reservoir are in fluid communication with the pump. The reservoir has at least one engagement member, and the liquid passage and the air passage are located in the engagement member. The refill container has at least one sealing member, and the refill container is configured to be releasably attached to the reservoir such that the refill container is in fluid communication with the reservoir. When the refill container is attached to the reservoir, the engagement member engages the sealing member to cause the liquid passage and the air passage to be in fluid communication with the refill container.
