A foam dispenser includes an air pump for pumping and outputting air, a liquid pump for pumping and outputting liquid soap, a mixing chamber for receiving the liquid soap and the air, and a controller for inversely controlling the outputs of the liquid pump and the air pump. A method of controlling the quality of foam produced by a foam dispenser including a liquid soap pump and an air pump includes simultaneously inversely varying the output of each of the pump for adjusting the quality of the foam produced.

Methods, systems and apparatus for operating a liquid dispenser based on the number of revolutions of the motor causing the dispensing operation and/or based on the linear distance traveled of the piston driving the dispensing pump.

A foam soap-providing machine with function of recycling soap-liquid, which comprises: a container containing a soap-liquid and having a soap-releasing portion; a shell-group including at least two detachable shell-bodies combinedly disposed on the outer peripheral surface of the soap-releasing portion; and a faucet mounted on the upper end of the soap-releasing portion and having a soap-feeding portion provided for flowing out the pressurized soap-liquid; wherein the soap-feeding portion has a joint end; wherein a foam-generating module used to generate a foam and a foam-recycling module used to recycle the extruded unused foam are comprised in the shell-group; thereby it can generate foam and recycle the remaining foam in the soap-releasing portion through a single motor. Accordingly, the present invention greatly saves the structural volume and prevents the soap-liquid from being dropped outside and wasted.

A foam dispenser includes a dispensing outlet, a pre-mixing chamber receiving liquid from a liquid source and air from an air source, a mixing chamber downstream of the pre-mixing chamber and proximate the dispenser outlet, and a first conduit coupling the pre-mixing chamber to the mixing chamber.

An automatic foam soap dispenser includes a liquid soap dispenser, an activation unit, and an actuation unit. The liquid soap dispenser includes an outlet, a fluid reservoir for containing liquid soap, and a pump being depressed for dispensing the liquid soap in the fluid reservoir to the outlet. The activation unit includes a sensor for detecting a presence of a user of the liquid soap dispenser, and a motor having a transmission shaft, wherein the motor is activated by the sensor for generating a rotational power to the transmission shaft. The actuation unit includes a pressing member and a linkage system arranged to transmit the rotational power from the motor to a linear movement to the pressing member so as to drive the pressing member to depress the pump.

Systems and methods for a multi-function lavatory fixture are disclosed. The lavatory fixture includes a first and second leg, where a first end of each leg is configured to be mounted to a deck and a second end of each leg is located over a basin of the lavatory fixture. A connecting section extends between the second ends of each leg and includes outlets to dispense water and soap to wash a user's hands. The fixture also includes indicators located proximate each of the outlets to indicate to the user the location of each outlet. A sensor located near each outlet identifies the presence of a user's hands near the outlet and dispenses water and soap, accordingly. A controller within the lavatory fixture receives inputs from each sensor and activates the appropriate pump or valve to deliver the desired product at the appropriate outlet.

A piston pump with a piston chamber-forming body and a piston-forming element relatively coaxially reciprocally movable to dispense liquid and air from a discharge outlet, which the discharge outlet is fixed relative to the piston chamber-forming body.

A pivot-to dispense soap pump includes an actuator that dispenses soap when actuated. The actuator is configured to move downward when actuated by user input. The downward movement may be in either one of a linear movement, maintaining the actuator is a horizontal orientation, or a pivoting movement about a pivot point. The pivot point is located on a distal end of the actuator, which is opposite the nozzle. The pivoting motion allows a user to depress the actuator proximate to the nozzle, thereby allowing the user to dispense soap into the same hand used to actuate the actuator. As a result, efficient, one-handed soap pumping and dispensing is enabled.

A product dispenser holder comprises a dispenser holder body configured to receive a product dispenser that stores a supply of a product to be dispensed, an actuation sensor that senses actuations of the product dispenser, and an actuation button, such that when an actuation force is applied to a pump of the product dispenser, a substantially downward force is applied to the actuation button causing the actuation button to rotate substantially downwardly and actuate the actuation sensor to generate a dispenser actuation signal.
