Detailed ways

In order to make the examiner more aware of the features, structures and effects of the present utility model, the following descriptions of the following embodiments, drawings and figure numbers are hereby given;

As shown in Figures 5 to 8, the disc unit of the coffee grinder of the present invention comprises an inner grinding seat 31 and an outer grinding seat 32, wherein:

An inner grinding seat 31, the center of which is provided with a coupling hole 311 for the coupling of the grinder rotating shaft 40, so that the inner grinding seat 31 can be rotated by the rotating shaft 40, and the upper end of the inner grinding seat 31 has first arc-shaped convex ribs arranged in a staggered ring 312 and the second arc-shaped rib 313 which is smaller than the first rib 312, the lower end ring is provided with internal grinding teeth 314, as shown in Figure 6, each first arc-shaped rib 312, viewed from the top, is arranged diagonally at four corners , roughly forming a quadrilateral, but not limited thereto, and an arc-shaped guide groove 315 is respectively formed between the adjacent first arc-shaped ribs 312 and the second arc-shaped ribs 313, as shown in FIG. 6 , each The second arc-shaped convex rib 313 is protruded from the top edge of the two first convex ribs 312 downwards and gradually increases from low to high (that is, gradually expands), so as to guide the broken coffee grains into the clamp sequentially from large to small Burst. the

An outer grinding seat 32, which is an annular sleeve, has a joint flange 321 protruding from its top end, and the joint flange 321 is provided with a joint hole 322 for a joint grinder. The feed channel 323 (as shown in Figure 7) of the arc-shaped guide groove 315 is provided with an outer grinding tooth 324 meshing with the inner grinding 314 at the lower end; If it is not limited by this shape, a clamp is formed between each feeding channel 323 and each first arc-shaped convex rib 312 and each second arc-shaped convex rib 313, which can be broken by the coffee beans 50 feeding ejector. The clamping space A can be crushed by the clamping space A after the beans are placed; in addition, the lower ends of the feeding channels 323 are terminated with semicircular arcs, so that the outer grinding teeth 324 located below can extend to two semicircles A triangular grinding tooth portion 325 is formed between the arcs, so that each triangular grinding tooth portion 325 and each semicircular feeding channel 322 form a staggered arrangement, so as to have the functions of staggered clamping and breaking and tooth-shaped grinding. the

As shown in Fig. 5 and Fig. 8, the disc unit of the present invention further includes a guide sleeve 60, the upper end of which is provided with a socket portion 61 sleeved with the lower end of the outer grinding seat 32, and guides the concentrated grinding The ground coffee falls into the funnel-shaped guide part 62 at the lower preset container position. the

As shown in Figures 7 and 8, when actually grinding, the coffee beans 50 are inserted into the semicircular feeding channel 323 of the outer grinding seat 32 and the first and second arc-shaped convex ribs of the inner grinding seat 31. Each clamping space A formed by 312, 313 is limited by its clamping, so when the inner grinding seat 31 is rotated and ground, the coffee beans 50 can be clamped on top by rotating the first and second arc-shaped ribs 312, 313. Each semi-circular feeding channel 323 has a groove wall, so that the coffee beans 50 can be pinched and broken quickly, thereby increasing the bean feeding speed, and the crushed coffee beans 50 are quickly guided into the lower end by each arc-shaped guide groove 315 The inner and outer grinding teeth 314, 324 are ground into powder particles. Therefore, the utility model can achieve the benefits of quickly and effectively shortening the grinding time through the design of each clamping space A, and can avoid excessive grinding time. Acidity occurs. the

As shown in Figure 5, the utility model uses the lower ends of the semicircular feeding channels 323 and the triangular grinding teeth 325 extending from the outer grinding teeth 324 to form a staggered arrangement, so that the broken coffee beans 50 can be reused when they enter here. The pinching and grinding effect of the top trigger promotes the excellence of grinding efficiency. the

To sum up, the utility model can effectively improve the practicability and progressive benefits of achieving the industrial competitive advantage, and has industrial versatility, novelty and creativity, and obviously meets the requirements of the new patent; however, the above is only the preferred aspect of the utility model Embodiment is only, not therefore promptly limit the patent scope of the present utility model, so all the simple modifications and equivalent structural changes made by using the specification of the present utility model and the accompanying drawings; all should be included in the patent scope of the present utility model in the same way , together with Chen Ming. the
