Description

Technical Field

[0001] The utility model relates to the technical field of coffee grinding, in particular to a shark tooth cone cutter disc for a coffee bean grinder. Background Art

[0002] Coffee has become increasingly popular around the world for its unique aroma and taste, as well as its ability to refresh the mind. A coffee grinder is a must-have device for brewing coffee, which grinds coffee beans into small coffee particles for brewing. The blade disc, as the core component of the coffee grinder, directly affects the particle uniformity, amount of fine powder, and grinding efficiency of the ground coffee powder. The conical blade disc rotates and cooperates with the outer ring blade disc fixed on the outer ring, and the coffee beans are ground in the gap between the two.

[0003] However, it is found that some coffee beans are larger in size and will be ground and squeezed between the conical blade disc and the outer ring blade disc during the falling process, resulting in beans and powder stuck. This results in low grinding efficiency and affects the brewing taste and flavor. A conical blade disc that can solve the above problems is urgently needed. Utility Model Content

[0004] In order to solve the problems of the prior art, the utility model provides a shark tooth cone blade disc for a coffee bean grinder, aiming to provide a cone disc with high grinding efficiency and good uniformity of ground particles.

[0005] The utility model solves the technical problem by adopting the following solution: a shark tooth cone cutter disc for a coffee bean grinder, comprising a cone-shaped body, the outer wall of the cone-shaped body being provided with a plurality of inclined grinding blades, the grinding blades comprising a square tooth portion located at a small diameter end for preliminarily chopping the coffee beans and an ridge tooth portion located at a large diameter end, the ridge tooth portion being further provided with a powder discharge arc groove for increasing the powder discharge speed.

[0006] By adopting the above technical solution, the coffee beans entering the cutter disc are initially chopped by using the square teeth composed of multiple flat teeth at the small diameter end, and large particles are quickly crushed to avoid squeezing due to excessively large particles. The coffee beans are then finely ground by the multiple ridge teeth on the large diameter end at the middle and lower position, avoiding bean jams and improving grinding efficiency, and the coffee powder has high uniformity. The powder discharge arc groove is arranged on the ridge teeth to increase the discharge speed of the coffee powder, reduce the phenomenon of clogging and jamming, and maintain the continuity of the grinding process.

[0007] Furthermore, each of the grinding blades is evenly arranged at equal angles along the circumference of the conical body.

[0008] By adopting the above technical solution, the evenly distributed grinding blades ensure that the pressure exerted by each blade on the coffee beans is balanced and consistent, which can avoid uneven grinding caused by excessive or insufficient local pressure, resulting in reduced particle uniformity, thereby improving the grinding quality.

[0009] Furthermore, the grinding blades are provided in seven groups.

[0010] By adopting the above technical solution and setting seven sets of grinding blades, the grinding fineness and grinding efficiency can be improved.

[0011] Furthermore, the grinding blade gradually widens from top to bottom.

[0012] Furthermore, an oblique groove is formed between each adjacent grinding blade, and the oblique groove gradually narrows in an arc shape from top to bottom.

[0013] By adopting the above technical solution, the chute can be used to discharge coffee powder, and the tooth portion can be gradually widened by narrowing from top to bottom, which is conducive to gradually grinding the coffee powder from coarse to fine, thereby improving the grinding efficiency and quality.

[0014] Furthermore, a mounting hole for connecting the rotating shaft for coaxial rotation is provided on the central axis of the conical body, and a positioning hole is also provided on the bottom surface of the conical body.

[0015] By adopting the above technical solution, the coffee grinder shaft is inserted into the installation hole and fixed in place through the bottom positioning hole, ensuring that the blade disc rotates concentrically driven by the shaft, thereby ensuring the grinding efficiency and consistency of the powder particles.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the utility model adopts a multi-stage grinding design, uses a square tooth portion at the small diameter end of the conical cutter disc for preliminary chopping, and sets an ridged tooth portion at the large diameter end for fine grinding, effectively reducing grinding resistance, improving grinding efficiency, and making coffee powder more uniform. The powder discharge arc groove is set on the ridged tooth portion to increase the powder discharge speed and avoid powder jamming.

[0017] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0025] like Figures 1 to 3 As shown, a shark tooth cone cutter disc for a coffee bean grinder can provide a cone disc with high grinding efficiency and good uniformity of ground particles; wherein this embodiment includes a cone body 1, the outer wall of the cone body 1 is provided with a plurality of inclined grinding blades 2, the grinding blades 2 include a square tooth portion 21 located at the small diameter end for preliminarily chopping the coffee beans and an ridge tooth portion 22 located at the large diameter end, and a powder discharge arc groove 3 for increasing the powder discharge speed is also provided on the ridge tooth portion 22.

[0026] This embodiment sets a two-stage grinding structure on the outer wall of the conical cutter disc. First, a group of square teeth 21 composed of multiple flat tooth protrusions are designed at the small diameter end of the cutter disc. The square teeth 21 can perform the initial crushing process on the coffee beans entering the cutter disc, quickly crush the large particles to a suitable size, and effectively prevent the extrusion problem caused by the particles being too large. Then, the ridge teeth 22 arranged in a staggered manner on the ridges at the large diameter end of the middle and lower positions are used to finely grind the coffee beans, thereby ensuring that the coffee beans are fully ground and avoiding the phenomenon of bean jamming, significantly improving the overall grinding efficiency, and making the ground coffee powder uniform in particle size. In order to improve the discharge efficiency of coffee powder and the continuity of grinding, a powder arc groove 3 is set on the ridge teeth 22 to increase the discharge speed of coffee powder, reduce the phenomenon of powder jamming, and achieve high-efficiency grinding.

[0027] like Figure 1As shown, the grinding blades 2 of this embodiment are evenly arranged at equal angles along the circumferential direction of the conical body 1. The evenly distributed grinding blades 2 ensure that the pressure exerted by each blade on the coffee beans is balanced and consistent, which can avoid uneven grinding due to excessive or insufficient local pressure, resulting in reduced particle uniformity, thereby improving the grinding quality. The grinding blades 2 gradually widen from top to bottom, and an inclined groove 4 is formed between each adjacent grinding blade 2, and the inclined groove 4 gradually narrows in an arc shape from top to bottom. The inclined groove 4 can be used to discharge coffee powder, and by narrowing from top to bottom, the toothed portion 22 can be gradually widened, which is conducive to the gradual progress of coffee powder from coarse grinding to fine grinding, so as to improve the grinding efficiency and quality.

[0028] like Figure 2 As shown, the grinding blades 2 of this embodiment are provided with seven groups. By providing seven groups of grinding blades 2, the grinding fineness and grinding efficiency can be improved, ensuring that the coffee beans are fully and evenly ground.

[0029] like Figure 3 As shown, the central axis of the conical body 1 of this embodiment is provided with a mounting hole 5 for connecting the rotating shaft for coaxial rotation, and the bottom surface of the conical body 1 is also provided with a positioning hole 6. By inserting the rotating shaft of the grinder into the mounting hole 5 and positioning and fixing it through the bottom positioning hole 6, it is ensured that the rotating shaft drives the blade to rotate concentrically, thereby ensuring the grinding efficiency and the consistency of the powder particles.

[0030] The working principle of this embodiment is as follows: this embodiment adopts a multi-stage grinding design, uses a square tooth portion 21 at the small diameter end of the conical cutter disc for preliminary chopping, and sets an angular tooth portion 22 at the large diameter end for fine grinding, which effectively reduces grinding resistance, improves grinding efficiency, and makes coffee powder more uniform. By setting a powder outlet arc groove 3 on the angular tooth portion 22, the powder outlet speed can be increased to avoid powder jamming.

[0031] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
