Abstract
A household liquid dispensing apparatus includes a container for holding a household liquid and a pump for pumping the household liquid out of the container. The pump includes a pump chamber. A dip tube is adapted to be positioned in the container and communicates with the pump chamber. An exhaust tube communicates with the pump chamber and an outlet for the household liquid. A pump actuator mechanically drives the pump. A motor operatively engages the pump actuator. The motor is electrically connected to a power source. A switch is electrically connected to the motor and the power source. A trigger assembly is operatively connected to the switch to control power delivered to the motor. The trigger assembly is positioned under the outlet for the household liquid for easy actuation by an upturned hand.
