[0020] The following diagrams illustrate various embodiments of the present invention. For clarity, many practical details will be included in the following description. However, it should be understood that these practical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not essential. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0024] like Figures 1 to 4 As shown, a bean grinder of the present invention includes a body 1, a bean box 2 and a bean grinding assembly, the bean grinding assembly includes a motor 31, a dynamic grinding wheel 32 driven by the motor, a support seat 33, a bracket 34, an adjusting wheel 35 and a fixed grinding wheel 36, the adjusting wheel 35 is threadedly connected to the support seat 33, and the fixed grinding wheel 36 is fixedly connected to the bracket 34, the bracket 34 is provided with two grooves 341, and the inner side of the support seat 33 is correspondingly provided with three groups of protrusions that can be snapped into the grooves 341, the heights of the three groups of protrusions are different, each group of protrusions consists of two protrusions, and the two protrusions of the same group of protrusions are the same height; when the grooves 341 of the bracket 34 are snapped into the protrusion groups of different heights, different gaps are formed between the fixed grinding wheel 36 and the dynamic grinding wheel 32, and the three groups of protrusions are respectively a first protrusion group 331, a second protrusion group 332 and a third protrusion group 333, as shown in FIG. Figure 4As shown, the height H1 of the first lug group 331 is greater than the height H2 of the second lug group 332, and the height H2 of the second lug group 332 is greater than the height H3 of the third lug group 333. When the groove 341 is engaged with the first lug group 331, the gap between the fixed grinding wheel 36 and the movable grinding wheel 32 is suitable for grinding coarse coffee powder. When the groove 341 is engaged with the second lug group 332, the gap between the fixed grinding wheel 36 and the movable grinding wheel 32 is suitable for grinding medium coffee powder. When the groove 341 is engaged with the third lug group 333, the gap between the fixed grinding wheel 36 and the movable grinding wheel 32 is suitable for grinding fine coffee powder. During use, the desired coffee powder particle size can be obtained by engaging the groove 341 with the lug group of corresponding height (the first lug group 331, the second lug group 332, or the third lug group 333). Compared with the prior art, the coffee bean grinder of the present invention has the advantages of convenient adjustment, fast adjustment speed, and excellent user experience. The adjusting wheel 35 is only used to fine-tune the gap between the fixed grinding wheel 36 and the movable grinding wheel 32 after the groove 341 is engaged with one of the protrusion groups.

[0025] Furthermore, the protrusion is provided with a recess 334 , and the groove 341 is provided with a protrusion 342 which can be embedded in the recess 334 . The protrusion 342 cooperates with the recess 334 so that the bracket 34 is more firmly fixed on the support seat 33 and is not easy to fall off.

[0026] Specifically, the opening of the groove 341 is provided with an inclined surface 343 for the protrusion to slide in, and the inclined surface 343 is provided on both sides of the opening of the groove 341. The inclined surfaces 343 on both sides of the opening of the groove 341 can make the bracket 34 installed on the support seat 33 smoother.

[0027] The two protrusions are provided on both sides of the support seat 33 , and the two grooves 341 are also provided on both sides of the bracket 34 .

[0028] Optionally, a protective cover 4 is fixedly connected to the upper end of the bracket 34. When the grinder is in operation, the protective cover 4 prevents the user from coming into contact with the fixed grinding wheel 36 or the movable grinding wheel 32, effectively protecting the user's safety. The protective cover 4 allows the groove 341 of the bracket 34 to be snapped onto the protrusion group of the support base 33, thereby completing the installation of the fixed grinding wheel 36.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
