Table-top bottle electronic soap or sanitizer dispenser

A tabletop soap or sanitizer dispenser comprising:

• a bottle comprising a reservoir for containing soap or sanitizer fluid;
• a nozzle;
• a pump assembly comprising:
• a housing extending into the reservoir of the bottle;
• a pump comprising one or more liquid pump chambers and optionally one or more air pump chambers, wherein the one or more liquid pump chambers and the optional one or more air pump chambers are formed in a flexible diaphragm;
• a moveable pump fluid outlet nozzle in fluid communication with the pump;
• and
• a pump inlet in fluid communication with the pump and the reservoir;
• a drive assembly comprising:
• a switch for detecting movement of the moveable pump nozzle;
• circuitry for controlling operation of the pump;
• a motor for driving the pump;
• and
• a battery for providing power to the pump;
• wherein moving the movable pump nozzle downward causes the circuitry for controlling the pump to actuate the pump to dispense fluid.

A tabletop soap or sanitizer dispenser comprising:

• a bottle comprising a reservoir for containing soap or sanitizer fluid;
• the bottle having a neck with an upper surface;
• the neck having an inner diameter and an outer diameter;
• a nozzle;
• a sensor for activating the tabletop dispenser;
• a pump;
• the pump having
• a diaphragm housing,
• a diaphragm body;
• the diaphragm body having one or more liquid pump chambers and optionally one or more air pump chambers, wherein the one or more liquid pump chambers and the optional one or more air pump chambers are operated sequentially a plurality of times for each dispense of fluid;
• and
• a diaphragm cover;
• a liquid pump inlet;
• a fluid outlet;
• the fluid outlet is in fluid communication with the nozzle;
• the diaphragm housing having an outside diameter;
• wherein the outside diameter of the diaphragm housing has a diameter that is the same sizes as the outer diameter of the neck;
• a drive housing extending into the reservoir of the bottle;
• a motor and a battery located in the drive housing;
• and
• control circuitry;
• wherein when the sensor provides a signal to the control circuitry to dispense a dose of fluid, the control circuitry causes the motor to rotate the pump to dispenses a dose of fluid from the nozzle.
