[0030] Please refer to Figure 1 And Figure 2 , an embodiment of the application provides a kind of beverage brewing assembly, beverage brewing assembly includes extraction cup 330 and first driving device, first driving device is connected with extraction cup 330, and can drive extraction cup 330 along specific movement locus Periodic motion. Beverage brewing assembly is applied in coffee machine, and first driving device is installed in the host 100 of coffee machine.

[0031] Since the first driving device can drive the extraction cup 330 to move periodically along the specific movement locus, the position of the extraction cup 330 along the specific movement locus can change periodically, and the extraction cup 330 can oscillate periodically along the specific movement locus. After the hot water enters the extraction cup 330, the extraction cup 330 is driven by the first driving device to oscillate periodically along the specific movement locus, so that the hot water and the coffee powder can be mixed uniformly, and the coffee powder can be extracted uniformly.

[0032] In other embodiments, the beverage brewing assembly is not limited to be applied to coffee machines, but can also be applied to other beverage machines to brew other beverages (juice, tea, etc.).

[0033] Please refer to Figure 1 and Figure 2 In an embodiment, the beverage brewing assembly further comprises a fixed support 200 and a mounting support 210. When the beverage brewing assembly is applied to a coffee machine, the fixed support 200 is arranged on the main machine 100 of the coffee machine, the first driving device is mounted on the fixed support 200, and the mounting support 210 is used to mount the extraction cup 330.

[0036] When the first driving device drives the first end 451 of any eccentric shaft 450 to rotate around its own axis, the second end 452 of the eccentric shaft 450 moves around the first end 451 and drives the mounting support 210 to move. Since the first end 451 of each eccentric shaft 450 is rotatably connected to the fixed support 200 around its own axis, and the second end 452 of each eccentric shaft 450 is rotatably connected to the mounting support 210 around its own axis, the first end 451 of each eccentric shaft 450 rotates around its own axis relative to the fixed support 200, and the mounting support 210 and the second end 452 of each eccentric shaft 450 are connected to each other to make a circular motion with the same radius around the axis of the corresponding first end 451. Therefore, according to the law of rigid body translation, it can be known that any point on the mounting support 210 makes a translational motion along a circular track.
