Detailed Description

The positional relationship described in the following embodiments includes: the top, bottom, left and right, unless otherwise indicated, are based on the orientation of the elements in the drawings.

Referring to fig. 1 to 3, a bean grinder structure 1 of the present application includes: a hollow shell 2, a bean grinding mechanism 3, a grinding adjusting mechanism 4, a power mechanism 5, and a bearing seat 6, wherein the hollow shell 2 has an upper opening 21 and a lower opening 22, a first bearing seat 23 is disposed at the center, an external thread 211 is disposed at the proximal edge of the upper opening 21, and an internal thread 221 is disposed at the proximal edge of the lower opening 22. Three sets of positioning beads 24 are provided in different orientations on the hollow housing 2 below the external thread 211. In addition, the upper and lower edges of the first shaft seat 23 are provided with a bearing set 25, and the bearing set 25 includes a bearing cover 251 and a bearing 252 for providing a lubricating effect when the transmission shaft 31 of the bean grinding mechanism 3 rotates.

The bean grinding mechanism 3 is assembled in the hollow housing 2, and includes: a transmission shaft 31, a top bearing 32, a top bearing cover 33, a positioning cover 34, a bearing seat 35, an inner cutter disc 36, an outer cutter seat 37 and an outer cutter disc 38, wherein the transmission shaft 31 is assembled on the first shaft connecting seat 23, the upper end of the transmission shaft is assembled with the top bearing 32 and the top bearing cover 33, part of the transmission shaft is exposed out of the hollow shell 2 to be a polygonal body, and is provided with an external thread 311 which is screwed with a screw hole 341 of the positioning cover 34, the lower end of the transmission shaft is assembled with the inner cutter disc 36 and is provided with a screw hole 312, and the inner cutter disc 36 is supported by a bolt 314 through a nut 313. The inner cutter 36 is located inside the outer cutter 38 and has a plurality of outer teeth 361, and forms a discharge port 382 with the bottom edge of the outer cutter base 37. The outer holder 37 is a hollow body, one end of which is provided with an external thread 371 screwed with the internal thread 221 of the hollow housing 2, and the other end of which is provided with an internal thread 372, and the outer surface of the outer holder 37 is a rough surface 373 for providing friction. The bearing seat 35 is disposed above the outer cutter 38, the outer cutter 38 is a hollow body, a plurality of inner twisted teeth 381 are disposed on an inner peripheral surface of the hollow body, and a portion where the inner twisted teeth 381 and the outer twisted teeth 361 are engaged corresponds to the discharge port 382. A compression spring 39 is disposed above the inner cutter 36, the compression spring 39 is sleeved on the transmission shaft 31, and one end 391 of the compression spring abuts against the bearing cover 251; the other end 392 abuts the upper edge of the inner cutter head 36 to provide the proper cushioning force.

The grinding adjustment mechanism 4 includes an adjustment slide 41 as a hollow body, and an internal thread 411 connected to the external thread 211 of the hollow housing 2 is disposed below the adjustment slide 41, it should be noted that, in a normal state, when the adjustment slide 41 and the hollow housing 2 are locked to the discharge port 382 by clockwise screwing for a minimum distance (grinding of finer coffee powder), the external thread 211 and the internal thread 411 still keep a short distance (see fig. 4 reference sign T), and when the adjustment slide 41 is locked to the screw locking distance T by counterclockwise screwing, the discharge port 382 is at a maximum distance (grinding of coarser coffee powder). In addition, a second shaft connecting seat 412 is provided in the adjusting slide seat 41 for connecting the transmission shaft 31 of the bean grinding mechanism 3. In addition, the adjusting slide 41 is provided with a wave groove 413 corresponding to the positioning bead 24, so that when the adjusting slide 41 is adjusted, a step feeling can be generated, and a user can clearly know a preferred step.

The power mechanism 5 provides hand power to the bean grinding mechanism 1, comprising; a joint cap 51, a game rod 52, a handle 53, wherein the joint cap 51 is assembled above the adjusting slide 41, and has a shaft sleeve 510 (fig. 4) assembled on the polygonal body of the transmission shaft 31, and a leakage-proof washer 511 is provided thereon to provide a tight fit with the adjusting slide 41.
