The upper end of the water guide hole 264 is communicated with the one-way valve water inlet assembly 50, so that high-temperature and high-pressure water injected by the one-way valve water inlet assembly 50 can be injected into the coffee capsule 80 (shown in figure 9) through the two water injection holes 265 and 266 to form vortex convection impact, the concentration of the extracted coffee powder is higher and more fragrant and mellow than that of the coffee powder extracted by a conventional water inlet mode, and the capsule beverage which is dissolved quickly is extracted more thoroughly than that of the conventional water inlet mode.

Referring to fig. 7 in conjunction with fig. 3, the cup body assembly 30 is mainly composed of a cup body shell 31, a cup body top ring 32, a spring 33, a top ring pressing cover 34, a coffee discharging bayonet 35, a flow stopping sealing ring 36, a coffee liquid collecting box 37, a coffee discharging conduit 38 and a coffee discharging nozzle 39. The entire cup body assembly 30 is laterally removably mounted by sliding both sides of the cup body housing 31 along the guide steps 12 and 13 of both sides of the mounting groove 11 of the housing assembly 10, respectively. An extraction chamber 311 is formed on the cup body housing 31 for placing a coffee capsule or a coffee powder box. The cup body top ring 32 is elastically supported at the bottom in the extraction cavity 311 through a spring 33 and is limited by a top ring gland 32. The coffee discharging bayonet 35 is fixed at the bottom of the extraction cavity 311, the coffee collecting box 37 is installed below the extraction cavity 311 of the cup body shell 31, and the stop seal ring 36 is abutted between the coffee collecting box 37 and the cup body shell 31 to form a seal. The coffee outlet nozzle 38 and the coffee outlet nozzle 39 are disposed on the other side of the cup body shell 31 far away from the extraction chamber 311 and are communicated with the coffee liquid collecting box 37.

Referring specifically to fig. 8, the coffee bayonet 35 includes a mounting portion 351 and a blade portion 352 provided at an upper end of the mounting portion 351. The blade portion 352 has a flat shape, a blade edge 353 is formed at one end of the blade portion 352, a stepped surface 354 is formed at the other end, and the blade portion 352 is provided with a coffee fluid discharge hole 355 below the stepped surface 354. The design has the advantages that when the extraction is started, the knife tip 353 of the coffee-discharging bayonet 35 pierces the bottom of the coffee capsule 80 and enters the coffee capsule 80, the step surface 354 abuts against the bottom of the coffee capsule 80, the bottom of the coffee capsule 80 is still blocked by the knife-edge part 352, and the coffee liquid cannot flow out; when the coffee capsule 80 has been extracted for a certain time and the pressure of 3-5BAR is applied to the coffee capsule 80, the coffee capsule 80 swells and the bottom moves down to the coffee outlet 355 of the blade portion 352, and the extracted coffee in the coffee capsule 80 flows out through the coffee outlet 355, as shown in fig. 9. This design provides more efficient extraction than conventional coffee-making bayonet.

The brewing device of the coffee machine according to the above-mentioned embodiment of the present application works as follows: first, as shown in fig. 1 and 3, in the initial state, the operating rod 41 is in the open state, the lid assembly 20 is supported by the plurality of springs 16 disposed in the housing assembly 10 at the upper end of the upward and downward movement stroke shown by the arrow 92, and the user can load the coffee capsule or coffee powder cartridge into the extraction chamber of the cup body assembly 30. Then, as shown in fig. 2 and 4, the cup body assembly 30 is firstly installed in the installation groove 11 below the shell assembly 10 along the guiding steps 12 and 13; then, the operating rod 41 is rotated to be pressed downwards to a closed state, and the cup lid assembly 20 is driven by the first connecting rod 42 and the second connecting rod 43 to move downwards to a position sealed with the cup body assembly 30, at this time, the water inlet bayonet 26 of the cup lid assembly 20 punctures the coffee capsule or the coffee powder box in the extraction chamber 3211, and the high-temperature and high-pressure water is injected into the water guide hole 264 at the center of the water inlet bayonet 26 through the check valve water inlet assembly 50 and then is injected into the coffee capsule or the coffee powder box from the two water injection holes 265 and 266 for extraction. When the pressure of 3-5BAR is applied to the coffee capsule or coffee powder cartridge, the coffee capsule or coffee powder cartridge swells and the bottom thereof moves down to the coffee fluid outlet hole 355 of the knife portion 352 of the coffee bayonet 35, so that the extracted coffee fluid flows into the coffee fluid collecting cartridge 37 through the coffee fluid outlet hole 355. As further shown in FIG. 4, the bottom of the flow stop gasket 36 is further provided with a rim 361 contacting the bottom surface of the coffee cartridge 37, such that the rim 361 is not forced to flow into the abutting coffee outlet nozzle 38 and out of the coffee outlet nozzle 39 until the pressure of the coffee in the coffee cartridge 37 is sufficient. After extraction, the operating rod 41 is turned back to the open state or the operating rod 41 is directly loosened, the cup cover assembly 20 can also return to the initial position under the action of the elastic restoring force of the spring 16, and a user can move the cup body assembly 30 out of the mounting groove 11 for cleaning and replacement. Because the cup body assembly 30 adopts the removable design, the brewing device of the coffee machine according to the embodiment of the present application can be provided with a plurality of cup body assemblies 30 with different extraction cavities 311 to be suitable for coffee capsules and coffee powder boxes with different shapes and sizes, and the applicability is diversified.
