A coffee maker includes a water storage device having a water tank and a water outlet piping communicating with the water tank; a driving device having a driving motor and a driving shaft; and a swing device having a rotating mechanism mounted on the driving shaft and a shifting mechanism connected to the water outlet piping and moving along with the rotating mechanism when the latter rotates. The water outlet piping is brought by a horizontal rotational movement of the rotating mechanism and a linear movement of the shifting mechanism to swing and shift in a spiral rotational course from a center point to outer and inner areas of a filter in a reciprocating motion while pouring water at controlled volume and stability, enabling ground coffee beans on the filter to be quickly and evenly extracted by water to release aromatic smell and sweet flavor just like drip brewing manually.

1. A coffee maker, comprising: a water storage device including a water tank and a water outlet piping communicating with the water tank;a driving device including a driving motor and a driving shaft outwardly extended from the driving motor; anda swing device being mounted between the water outlet
1. A coffee maker, comprising: a water storage device including a water tank and a water outlet piping communicating with the water tank;a driving device including a driving motor and a driving shaft outwardly extended from the driving motor; anda swing device being mounted between the water outlet piping of the water storage device and the driving shaft of the driving device, the swing device including a rotating mechanism and a shifting mechanism, the rotating mechanism being mounted on the driving shaft of the driving device, andthe shifting mechanism being connected to the water outlet piping of the water storage device, andthe shifting mechanism being connected to the rotating mechanism to move along with the driving shaft of the driving device,wherein the rotating mechanism brings the whole shifting mechanism to rotate while the shifting mechanism linearly shifts in a horizontal plane, and the water outlet piping is brought by the rotating mechanism and the shifting mechanism, while the coffee maker is in a water discharging state, to rotate and shift in a spiral course. 2. The coffee maker as claimed in claim 1, wherein the rotating mechanism includes a rotating assembly connected to the driving shaft, anda turntable connected to the rotating assembly and provided with a linear slide rail extending from a central area of the turntable toward a peripheral outer area of the turntable, and whereinthe shifting mechanism includes a set of holding seats fixedly mounted on the turntable,a screw rod having a first end portion rotatably connected to the set of holding seats, anda second end portion outwardly projected from the set of holding seats,a movable member received in the linear slide rail, the movable member having an end connected to the screw rod, andanother opposite end connected to the water outlet piping,a link mounted to the second end portion of the screw rod, anda stationary member being in contact with the link. 3. The coffee maker as claimed in claim 2, wherein the rotating assembly includes a first gear mounted on the driving shaft,a second gear meshing with the first gear, anda tubular member having an end connected to the second gear andanother opposite end connected to the turntable,and the tubular member being provided, at the another opposite end connected to the turntable, with a shift slot corresponding to the linear slide rail. 4. The coffee maker as claimed in claim 2, wherein the set of holding seats is located at two opposite ends of the linear slide rail so as to be on the turntable, and each of the holding seats being in a form of a fixed plate perpendicular to the turntable, and the fixed plates being formed, at respective center thereof, with a through hole, so that the screw rod is rotatably extended through and supported in the two through holes. 5. The coffee maker as claimed in claim 2, wherein the stationary member and the link are two meshing gears of a gear set. 6. The coffee maker as claimed in claim 5, wherein the two meshing gears of the gear set are selected from the group consisting of a crown gear and a spur gear meshed together, anda first bevel gear and a second bevel gear meshed together. 7. The coffee maker as claimed in claim 2, wherein the movable member is internally provided with a bearing for connecting with the water outlet piping, such that the water outlet piping does not rotate along with the rotating mechanism when the rotating mechanism rotates. 8. The coffee maker as claimed in claim 7, wherein the water outlet piping includes a fixed pipe coupled with the bearing, anda movable pipe adapted to shift along with the rotating mechanism and the shifting mechanism, the movable pipe being connected at an end thereof to the water tank of the water storage device and at another opposite end of the movable pipe to the fixed pipe. 9. The coffee maker as claimed in claim 1, wherein the water storage device further includes a heating unit for raising a temperature of water stored in the water tank, and a thermostat unit for maintaining the stored water at a temperature for coffee brewing. 10. The coffee maker as claimed in claim 1, further comprising a housing, within which the water storage device, the driving device and the swing device are received. 11. The coffee maker as claimed in claim 10, wherein the housing includes a base having a water-catching recess formed on one side of an upper surface of the base;a hollow column being connected at a lower end thereof to another side of the upper surface of the base for receiving the water storage device therein, and being provided on one side facing toward the water-catching recess, the hollow column having an aperture, via which the water outlet piping is outwardly extended from an interior of the hollow column; anda top connected to an upper end of the hollow column for receiving the driving device and the swing device therein, the top being provided at a position facing toward and corresponding to the water-catching recess with an opening, via which the swing device is connected to the water outlet piping. 12. The coffee maker as claimed in claim 11, wherein the base, the hollow column and the top of the housing together define between them a brewing space, in which a coffee filter and an extracted-liquid-holding vessel can be positioned. 13. The coffee maker as claimed in claim 11, wherein the water-catching recess has a funnel-shaped structure fitted therein, and the funnel-shaped structure having a narrow stem portion being height-adjustably connected to a locating seat formed in the base below the water-catching recess. 14. The coffee maker as claimed in claim 11, wherein the top of the housing is provided at one side with a control panel electrically connected to the driving device and the water storage device, allowing a user to set desired water temperature, water discharge volume and swinging rate for the coffee maker at the control panel. 15. The coffee maker as claimed in claim 11, further comprising: a locating seat formed in the base below the water-catching recess; anda funnel-shaped structure fitted into the water-catching recess, and the funnel-shaped structure has a narrow stem portion being connected to the locating seat so that the funnel-shaped structure is adjustable in height relative to the locating seat. 16. The coffee maker as claimed in claim 1, wherein the rotating mechanism is connected to the water outlet piping only though the shifting mechanism. 17. The coffee maker as claimed in claim 1, wherein the shifting mechanism is connected to the driving device only through the rotating mechanism.
