It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0024] like Figures 1 to 5 As shown, an adjustable coffee bean grinder according to a preferred embodiment of the utility model comprises a machine base, a first grinding wheel, a second grinding wheel and a driving assembly. The machine base is provided with a grinding chamber, and a feed port and a discharge port communicated with the grinding chamber. The first grinding wheel is rotatably arranged in the grinding chamber. The driving assembly is arranged on the machine base. The power end of the driving assembly is connected to the second grinding wheel and drives the second grinding wheel to rise and fall in the grinding chamber. The first grinding wheel and the second grinding wheel cooperate to grind beans. A connecting groove is provided at the junction of the discharge port and the grinding chamber, and the connecting groove is tangent to the side wall of the grinding chamber.

[0025] Therefore, in the embodiment of the utility model, the second grinding wheel can be driven up and down by the driving assembly to control the gap between the first grinding wheel and the second grinding wheel, thereby controlling the coarseness of the ground powder, and the adjustment is convenient and quick. A connecting groove is provided at the junction of the discharge port and the grinding chamber, and the connecting groove is tangent to the side wall of the grinding chamber. Such a design expands the range of the discharge port and makes it easier for the powder to fall out.
