A pressured drinking water dispenser includes a control device and an air and water connector inserted in the cap of a tank. The control device and the water connector are mutually connected with an air tube and a water tube between. The control device has a circuit board, an air pump and an electromagnetic valve. The air pump and the electromagnetic valve are mutually connected with an air joint and an air tube. The air and water connector is inserted in the cap of a tank, having an air joint and a water joint respectively connected with the air tube and the water tube. When the air pump is electrified to pump air, with the electromagnetic valve electrified to be closed, the air may flow orderly through the air route into the tank to become highly compressed air to force the drinking water therein to flow through the water route into the water container in the dispenser body.

What is claimed is: 1. A pressured drinking water dispenser comprising: a dispenser body; a control device having a circuit board, an air pump and an electromagnetic valve, said air pump and said electromagnetic valve mutually connected with an air tube via a control device air joint; an air and water connector inserted in a tank cap of a tank, said connector provided with a connector air joint and a connector water joint extending up and respectively connected with said air tube and a water tube, said air tube connecting said control device and said air and water connector and said water tube connecting said dispenser body and said air and water connector, said connector air joint communicating with said tank for air to flow into said tank, and said connector water joint connected with a water outlet tube extending down to a bottom of said tank; wherein air compressed by said air pump flows through said control device air joint, said air tube and said connector air joint when said air pump is electrified to operate, wherein air pumped by said air pump flows through said air tube into said tank when said electromagnetic valve is electrified to close, and wherein the air flowed into said tank becomes gradually highly compressed air in said tank and forces drinking water stored in said tank to flow out through said connector water joint and said water tube and automatically flowing finally into a water container in said dispenser body. 2. The pressured drinking water dispenser as claimed in claim 1, wherein when said electromagnetic valve is electrified, said electromagnetic valve is closed and does not let air flow through thereby letting the compressed air pumped by said air pump flow into said tank; and wherein when power to said electromagnetic valve is cut off, said electromagnetic valve is open and lets air flow through so that the compressed air in said tank may flow through said air tube and then out of said electromagnetic valve into outer air. 3. The pressured drinking water dispenser as claimed in claim 1, wherein said control device further has a cap, a separating plate and a funnel-shaped base; said separating plate is fixed between said cap and said funnel-shaped base, and said circuit board, said air pump and said electromagnetic valve are fixed on an upper surface of said separating plate; said funnel-shaped base is directly inserted into a receptive base of said dispenser body, said receptive base having a hollow interior for drinking water in said water tube to flow through and a water inlet formed in its lower end and communicating with the interior of said dispenser body, with said hollow interior forming said water container. 4. The pressured drinking water dispenser as claimed in claim 3, wherein said circuit board fixed on said separating plate is connected with three vertical sensing bars extending down into the interior of said funnel-shaped base, said three sensing bars consisting of a short bar, a medium bar and a long bar with different lengths and extending into the hollow interior of said receptive base, said air pump is under electrified condition and continues to pump air when the water level in said dispenser body contacts said medium and said long sensing bar, and said air pump is cut off from power to stop pumping operation when the water level contacts said short sensing bar. 5. The pressured drinking water dispenser as claimed in claim 1, wherein said tank cap has a water hole formed therein and said air and water connector has an upper end of its body shaped tapered down so as to fit tightly with said water hole of said tank cap. 6. The pressured drinking water dispenser as claimed in claim 1, wherein said control device further has a shell of a tapered cylindrical shape with an interior hollow, a tubular member formed in said interior hollow and having a mouth facing down and fitting around an outer surface of a mouth of said tank, a recess formed in an upper portion of said shell, a plurality of ribs formed spaced apart radially and projecting on an annular surface defining said recess, a center hole bored in the center of the bottom of said recess and communicating with said recess and said tubular member, said air and water connector inserted in said center hole, said circuit board, said air pump and said electromagnetic valve fixed in said interior hollow of said shell; a further comprising a water container having its lower end fitted in said recess of said shell and supported on said ribs, an insert tube extending down from the bottom of said container for said connector water joint to insert in, a container water tube extending up in said water container and having an upper opening and connected with said insert tube as integral, a faucet provided at an outer surface of the bottom of said water container, and drinking water in said tank flows through said water outlet tube in said tank, said connector water joint, said insert tube and said container water tube into the interior of said water container functioning as the water container of said dispenser body. 7. The pressured drinking water dispenser as claimed in claim 6, wherein a set of micro switch is further provided in said control device, positioned on the bottom of said recess of said shell, having three micro points on the upper surface; three sensing bars are provided in said water container, consisting of a short, a medium and a long sensing bar in different lengths, said air pump is electrified and continues to pump air when the water level in said water container immerses said short and said medium sensing bar, power to said air pump is cut off to stop pumping when the water level in the interior of said dispenser body immerses said long sensing bar. 8. The pressured drinking water dispenser as claimed in claim 1, wherein a bottom base is further provided for said tank to rest thereon, and a plurality of elastic vertical walls are spaced apart around on the outer circumference of said bottom base for constricting said tank, and a plurality of casters are provided under said bottom base to enable said bottom base together with said tank resting thereon to move around on the ground.
