A nozzle-moving device has four bases, two rails, a shaft, a moving module, a brewing module, a transverse driver, and a longitudinal driver. Each one of the two rails is longitudinally connected to two of the four bases. The shaft is transversely connected to two of the four bases. The moving module is slidably mounted to the two rails. The brewing module is slidably mounted to the moving module. The transverse driver and the longitudinal driver are respectively connected to the shaft and the brewing module via timing belts, so the brewing module may move in two directions. Moreover, a user may easily change to different brewing modes via the transverse driver, the longitudinal driver, and a solenoid valve connected to the brewing module.
