Detailed Description

In order to further disclose the features and technical contents of the present invention, please refer to the following detailed description and accompanying drawings, which are provided for reference and illustration purposes only and are not intended to limit the present invention.

Please refer to fig. 1, fig. 2 and fig. 3, which are a perspective view, a partial perspective exploded view and a schematic combined cross-sectional view of the present invention, respectively. The utility model provides a hand-operated bean grinder, which comprises a body 1, a transmission rod 2, an adjusting structure 3 and a hand-operated crank 4; wherein:

the main body 1 may be a cylindrical or bottle-can-shaped container, and the main body has a receiving space 10 therein, and the receiving space 10 extends upward along the body or bottle body of the main body 1 to form an inlet 100, the inlet 100 may be funnel-shaped for coffee beans to be ground or flavoring such as pepper granules to be poured into the receiving space 10 of the main body 1 from the inlet 100, so as to be conveniently ground into powder. Furthermore, a first cutter disc 11 is provided at a remote location of the receiving space 10 with respect to the insertion opening 100, the first cutter disc 11 being arranged in the body 1 in a generally fixed manner.

The transmission rod 2 is pivoted in the accommodating space 10 of the body 1. In the embodiment of the present invention, one or more pivot portions are provided in the accommodating space 10 of the body 1 according to the axial position of the transmission rod 2 pivoted therein, and the embodiment is a first pivot portion 12 and a second pivot portion 13, respectively, wherein the first pivot portion 12 is closer to the insertion opening 100 and has a first bearing 120, the second pivot portion 13 is closer to the first blade 11 and has a second bearing 130, and the first and

second bearings

120, 130 are respectively fixed on the transmission rod 2, so that the transmission rod 2 can be stably pivoted in the accommodating space 10. Furthermore, the upper end of the transmission rod 2 protrudes out of the insertion opening of the body 1, so as to be connected with the hand crank 4 for the rotation of the hand, and the lower end of the transmission rod 2 is provided with a second cutter disc 20 tangent to the first cutter disc 11, so that the grinding effect can be achieved by the tangency of the cutting edges on the first and

second cutter discs

11, 20.

As mentioned above, the second cutter head 20 is fixed to the lower end of the transmission rod 2 by a cutter seat 200 at the lower end of the transmission rod 2, and can be locked to the lower end of the transmission rod 2 from the center of the cutter seat 200 by a screw element 201, and can be further locked by another screw element 202. Meanwhile, a bottom cover 5 can be assembled under the body 1.

The adjusting structure 3 comprises an adjusting knob 30 for adjusting the axial displacement of the driving rod 2, and an elastic positioning component 31. Referring to fig. 4, the elastic positioning component 31 is disposed on the transmission rod 2 and has a positioning member 310 and an elastic element 311, the positioning member 310 can be a sphere, the elastic element 311 can be a spring, the adjustment knob 30 has a scale 300 radially surrounding and allowing the positioning member 310 to jump thereon, the scale 300 can be toothed or wavy and annularly disposed on an inner hole wall formed in the adjustment knob 30, so that the elastic element 311 pushes the positioning member 310 against the scale 300, when the adjustment knob 30 is rotated, the positioning member 310 can jump on the scale 300 to generate a hand feeling when adjusted, besides the axial up-and-down displacement of the transmission rod 2 can be adjusted, so that a user can feel the adjustment amount of the adjustment knob 30, thereby facilitating to know or determine the thickness or size of the grinding particles.

The hand lever 4 is connected to the transmission rod 2. In the embodiment of the present invention, one end of the hand crank 4 can movably penetrate into the upper end of the transmission rod 2; more specifically, the upper end of the transmission rod 2 is provided with a sleeve joint 21 for the crank 4 to movably penetrate, the sleeve joint 21 penetrates through the upper part of the sleeve joint 21 by a bolt 22, and penetrates through the crank 4 to be bolted on the transmission rod 2, and the elastic positioning component 31 can also be arranged on the hole 210 of the sleeve joint 21. The other end of the hand crank 4 can be provided with a grab handle 40, so that a user can push the hand crank 4 to drive the transmission rod 2 to rotate after holding the hand crank by hand, thereby achieving the grinding effect.

Therefore, the hand-operated bean grinder of the utility model can be obtained by the structure composition.

Accordingly, as shown in fig. 5, in the process of rotating the adjusting knob 30, the driving rod 2 can be driven by the adjusting knob 30 to move up and down axially, so as to adjust the distance between the first and

second cutter discs

11, 20, so that the size or thickness of the ground particles can be changed, and a restoring spring 23 can be disposed on the driving rod 2 to maintain the tightness between the first and

second cutter discs

11, 20. When the grinding particles are to be adjusted, since the adjusting knob 30 has the scale 300 and the positioning member 310 of the elastic positioning assembly 31 can jump on the scale 300 when being rotated, the user can feel the adjustment amount of the rotation through the jump (or slight vibration) of the positioning member 310 of the elastic positioning assembly 31 on the scale 300, so as to know and judge more clearly to control the thickness or size of the grinding particles.

It is worth mentioning that: the adjusting knob 30 may be provided with a twisting portion 301 with an enlarged outer diameter for facilitating the adjustment thereof by a human hand.

However, the above description is only a preferred and practical embodiment of the present invention, and the scope of the present invention is not limited thereby. Of course, the present invention can have other embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the claims of the present invention.
