Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and in particular to a coffee bean grinder. Background Art

[0002] Chinese utility model patent publication number CN208524577U discloses a removable coffee bean hopper device comprising a bean hopper assembly, a mounting base, a microswitch assembly, and a bean grinding device. The microswitch assembly is fixedly mounted on the mounting base and electrically connected to the bean grinding device. The mounting base is provided with a fixing member, through which the bean hopper assembly passes and is connected to the bean grinding device. The bean hopper assembly is provided with a locking member, which is provided with a slot on the bean grinding device and engages with the locking member. The fixing member is provided with a block and a groove. The locking member passes through the groove and rotates to achieve misalignment with the groove, and the block locks the bean hopper assembly onto the mounting base. The bean hopper assembly is provided with a raised structure, which activates and closes the microswitch assembly. When the bean hopper assembly is locked into the mounting base, one of the locking members must be installed in the corresponding groove for the raised structure on the bean hopper assembly to activate the microswitch. This leads to inconvenient installation and a poor user experience. Utility Model Content

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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:

[0023] like Figures 1 to 4 As shown, a coffee bean grinder according to the present invention comprises a body 1, a bean container 2, and a grinding assembly. The grinding assembly comprises a motor 31, a dynamic grinding wheel 32 driven by the motor 31, a support base 33, a bracket 34, a fixed grinding wheel 35, and a microswitch 36. The fixed grinding wheel 35 is fixed to the bracket 34, and the microswitch 36 is mounted on the body 1. The bracket 34 has two grooves 341, and the inner side of the support base 33 has three groups of protrusions that snap into place within the grooves 341. Each group of protrusions includes two protrusions, and there are three groups of protrusions in total: a first group of protrusions 331, a second group of protrusions 332, and a third group of protrusions 333. A circular ring 342 is provided on the upper portion of the bracket 34. When the bracket 34 is properly mounted on the support base 33, the circular ring 342 triggers the microswitch 36, thereby closing the microswitch 36. When the microswitch 36 is closed, the motor 31 rotates to grind the coffee beans when the grinder is powered on. Compared with the prior art, the present invention provides a circular ring 342 on the upper part of the bracket 34. When the bracket 34 is installed in place on the support base 33 (that is, the protrusion is embedded in the groove 341 and is misaligned with the groove 341), the circular ring 342 triggers the micro switch 36, thereby closing the micro switch 36. As long as any one of the first protrusion group 331, the second protrusion group 332, or the third protrusion group 333 is embedded in the groove 341 of the support base 33 and is misaligned with the groove 341, the circular ring 342 can trigger the micro switch 36, which has the advantages of easy installation and good user experience.

[0024] The height of the first block group 331 is greater than that of the second block group 332, and the height of the second block group 332 is greater than that of the third block group 333. When the groove 341 is engaged with the first block 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 block 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 block group 333, the gap between the fixed grinding wheel 36 and the movable grinding wheel 32 is suitable for grinding fine coffee powder.

[0025] Specifically, the middle portion of the bracket 34 is provided with a transition slope 343 that enables the ring 342 to smoothly trigger the micro switch 36. When the bracket 34 is placed in the support seat 33, the transition slope 343 first contacts the micro switch 36. When the bracket 34 continues to move downward, the ring 342 will trigger the micro switch 36.

[0026] Furthermore, a drive rod 4, biased by a spring 41, is provided on one side of the bean container 2. One end of the drive rod 4 contacts the ring 342, and the other end is connected to the microswitch 36. A through hole 21 is provided at the lower end of the bean container 2, allowing the drive rod 4 to pass through and contact the ring 342. The machine body 1 is provided with a holder 11, within which the microswitch 36, drive rod 4, and spring 41 are mounted.

[0027] The driving rod 4 is provided with a convex ring 42, one end of the spring 41 is pressed on the card seat 11, and the other end is pressed on the convex ring 42. The driving rod 4 is provided with a " "-shaped trigger surface 43.

[0028] The upper end of the bracket 34 is fixedly connected with a protective cover 5. The groove 341 of the bracket 34 can be snapped onto the projection group of the support seat 33 by the protective cover 5 to realize 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.
