摘要: A unit for dispensing water from a bottle. The parts of the unit include an air pump for pressurizing the bottle, a microswitch having a control button connected in circuit with the pump, a small pressure chamber with a distensible diaphragm for a top, a branched air line connecting the pump with the bottle and the pressure chamber, and a cabinet with rollers that can be rolled to a position of use around the upright bottle. Additionally, the unit includes a water line positioned to extend upwardly away from the bottle. A rubber cap encloses the bottle opening and the water line and a branch of the air line are in communication with the interior of the bottle by means of metal tubes passing through the cap. Fastened to the lower end of the metal tube for the water line is a section of flexible tubing long enough to reach to the bottom of the bottle. The microswitch is normally closed and the pressure chamber is positioned with its diaphragm close to the control button of the switch. When the air pressure in the bottle exceeds a certain limit, the diaphragm bulges outwardly into contact with the button and opens the microswitch. When water is drawn from the bottle through the water line, the air pessure drops, and the diaphragm shrinks away from the control button. This causes the microswitch to close and start the air pump operating to again build up air pressure in the bottle.
