Description

Technical Field

[0001] This utility model belongs to the field of grinding machine technology, and specifically relates to a grinding system for a coffee grinder. Background Technology

[0002] A coffee bean grinder is a key tool for making high-quality coffee. It grinds coffee beans into uniform particles for extraction and coffee making. The current grinding method of coffee beans is that the coffee beans are sent to the grinding blade assembly of the machine body by a screw rod through a spiral channel. When the screw rod pushes the coffee beans, the force on the beans is uneven, which causes some beans to be crushed prematurely, while other beans may not be ground enough, resulting in too much fine powder and coarse particles mixed together. Utility Model Content

[0003] This addresses the technical problem of uneven force distribution in existing coffee bean delivery methods in coffee grinders.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a grinding system for a coffee grinder, comprising an upper grinding blade assembly, a lower grinding blade assembly, a motor module, and a grinding chamber. The rotating shaft of the motor module extends into the grinding chamber. The lower grinding blade assembly is fitted around the outside of the rotating shaft and fixedly connected, so that the lower grinding blade assembly is assembled at the bottom of the grinding chamber. The upper grinding blade assembly is located in the grinding chamber and at the top of the lower grinding blade assembly. The teeth of the lower grinding blade assembly are opposite to the teeth of the upper grinding blade assembly. Coffee beans fall between the upper and lower grinding blade assemblies, and the grinding is completed through the meshing of the teeth. The grinding chamber has a powder outlet, from which the ground coffee powder is discharged.

[0005] Furthermore, the lower grinding tool assembly has a lower grinding disc and a lower grinding tool, the lower grinding tool being disposed on the surface of the lower grinding disc.

[0006] Furthermore, the lower grinding disc has several pushing components in the center, and these pushing components are located in the center of the lower grinding disc.

[0007] Furthermore, a graduated ring is provided on the outer side of the upper grinding assembly.

[0008] The present invention has the following advantages: The lower grinding blade assembly has a lower grinding disc and a lower grinding blade. The lower grinding disc is provided with several pushing components in the center. The lower grinding blade is located on the surface of the lower grinding disc, and several pushing components are located in the center of the lower grinding blade. In use, the coffee beans to be ground fall into the grinding chamber from the opening in the upper grinding blade assembly by gravity. The rotating lower grinding disc pushes the coffee beans between the upper and lower grinding blades for grinding through the pushing components, so that the coffee beans are ground more evenly.

[0013] like Figures 1 to 3 As shown, a grinding system for a coffee grinder includes an upper grinding blade assembly 10, a lower grinding blade assembly 20, a motor module 30, and a grinding chamber 40. The rotating shaft 31 of the motor module 30 extends into the grinding chamber 40. The lower grinding blade assembly 20 is fitted around the outside of the rotating shaft 31 and fixedly connected, so that the lower grinding blade assembly 20 is assembled at the bottom of the grinding chamber 40. In use, the motor module 30 drives the lower grinding blade assembly 20 to rotate via the rotating shaft 31.

[0014] The upper grinding shaving assembly 10 is located in the grinding chamber 40 and on top of the lower grinding shaving assembly 20. The teeth of the lower grinding shaving assembly 20 are arranged opposite to the teeth of the upper grinding shaving assembly 10. During use, coffee beans fall between the upper grinding shaving assembly 10 and the lower grinding shaving assembly 20 and are ground by the meshing of the teeth. The grinding chamber 40 has a powder outlet 41 on the side of the upper grinding shaving assembly 10 and the lower grinding shaving assembly 20. The ground coffee powder is then discharged from the powder outlet 41 of the grinding chamber 40.

[0015] The lower grinding blade assembly 20 has a lower grinding disc 21 and a lower grinding blade 22. The lower grinding disc 21 has several pushing components 23 in the center. The lower grinding blade 22 is located on the surface of the lower grinding disc 21, and several pushing components 23 are located in the center of the lower grinding blade 22. In use, the coffee beans to be ground fall into the grinding chamber 40 from the opening in the upper grinding blade assembly 10 by gravity. The rotating lower grinding disc 21 pushes the coffee beans between the upper and lower grinding blades for grinding through the pushing components 23, so that the coffee beans are ground more evenly.

[0016] The outer side of the upper grinding blade assembly 10 is provided with a scale ring 50. The scale ring 50 can be fixed to the grinder body by screws. The scale ring can be rotated to adjust its vertical displacement. The lower end of the scale ring and the upper blade support 11 of the upper grinding blade assembly 10 are fitted together. The grinding operation structure, namely the upper grinding blade assembly 10 and the lower grinding blade assembly 20, is axially arranged in the grinder body. Coffee beans flow out of the bean box by their own weight, pass through the scale ring 50 and fall into the grinding operation structure. At the same time, the scale ring is rotated to achieve vertical stability, so that the gap between the upper grinding blade assembly 10 and the lower grinding blade assembly 20 can be adjusted, thereby adjusting the coarseness of the coffee bean powder.
