ABSTRACT:
A coffee maker includes a valve mechanism having a micro switch, an electromagnetic valve, a magnetic covering board activated by the electromagnetic valve for opening or closing a powder path, and a spring interconnecting the covering board and the electromagnetic valve. A motor-driven grinding mechanism includes two ring-shaped outer grinding members having teeth facing each other, and a spring biased inner grinding member including a hollow feed rod with a lead screw formed thereon. A powder fineness adjusting mechanism includes an adjustment lever. In a powder fineness adjustment for producing coarse coffee powder, pivoting the lever toward one direction will pivot an abutment member and move the same outward to push one grinding member for increasing a space between the grinding members filled with coffee beans to be ground. Pivoting the lever toward the other direction will produce fine coffee powder.
