[0116] Take out the upper cup body 4, turn it to the upright state, align the bottom thereof with the top of the casing 1, and rotate the upper cup body 4 so that the outer thread and the inner thread are engaged, thereby completing the detachable connection of the upper cup body 4 and the casing 1, and making sure that the open mouth 141 of the upper cup body 4 communicates with the water inlet 11 of the casing 1, and the upper cup body 4 serves as a water tank.

[0117] Coffee powder placement operation:

[0118] First, detach the base 7 from the connecting cavity 16 of the casing 1, remove the filter cup 9, and expose the accommodating cavity 71.

[0119] Then, put back the filter cup 9, and then put the coffee powder into the filter cup 9.

[0120] Finally, reinstall the base 7 to the connecting cavity 16 of the machine shell 1, and make sure that the base 7 is tightly connected with the water outlet 12 of the machine shell 1.

[0121] The support arm 51 is unfolded:

[0122] At least two arc-shaped support arms 51 are rotated out of the ring body 53 of the machine shell 1, and the support arms 51 are rotated to the fully unfolded state.

[0123] Place the coffee machine on an empty cup (for example, the coffee cup 20 or the thermos cup 30 provided by the coffee machine, etc.), and make sure that the support arms 51 stably support the coffee machine above the cup, which is used to receive the coffee liquid.

[0124] Coffee capsule extraction process:

[0125] Add hot water into the upper cup body 4, press the function button 14 on the outside of the machine shell 1, and the water pump starts to operate. The pressurized water enters the water pump from the water inlet 11 of the upper cup body 4, and then enters the filter cup 9 through the water outlet 12 at the bottom of the machine shell 1. The water fully extracts the coffee powder in the filter cup 9, and the extracted coffee liquid flows into the base 7 from the third through hole 91 of the filter cup 9, and then is discharged into the cup through the coffee liquid outlet 311.

[0126] After the extraction is completed, press the function button 14 to turn off the water pump.

[0127] Extraction device 3 cleaning process:

[0128] Remove the base 7, take out the filter cup 9 from the containing cavity 71, clean the base 7 and the filter cup 9, and finally reinstall the base 7 and the filter cup 9 for next use.
