In this embodiment, the flow guiding block has a cross-shaped structure.
Referring to fig. 4 and 5, the brew chamber assembly 20 includes a brew housing 21 and an extraction base 22.
The brewing housing 21 is generally cylindrical in shape, mounted to an end sidewall within the housing 10, and the opening of the brewing housing 21 is disposed toward the brew head assembly 30. The brewing housing 21 has a chamber 211 for accommodating the capsule 200, the capsule 200 completing brewing within the chamber 211 and forming a beverage output outwards.
The brewing housing 21 is provided with a first flow channel 212 and a water outlet 213 communicating with the first flow channel 212, the first flow channel 212 being located at the bottom of the brewing housing 21, the first flow channel 212 being adapted to lead beverage formed in the capsule 200 to the water outlet 213, the water outlet 213 being adapted to collect beverage of the first flow channel 212 and to flow out. Wherein the water outlet 213 communicates with the spout 12 through the housing 10. The water outlet end of the water outlet 213 faces the arc inclined plane of the water outlet 12, the beverage flows from the water outlet end of the water outlet 213 to the arc inclined plane, the arc inclined plane buffers the flowing beverage and guides the beverage to the guide block of the water outlet 12, and the guide block guides and shunts the beverage, so that the beverage can smoothly flow into a cup which is placed in advance outside.
The extraction base 22 is mounted at the bottom of the chamber 211, and the edge of the extraction base 22 presses and seals the inner side wall of the brewing housing 21. The extraction base 22 is provided with a plurality of evenly distributed first piercing portions 221, each first piercing portion 221 being disposed towards the brew head assembly 30. Each first piercing portion 221 is correspondingly provided with a second flow passage 222, the second flow passage 222 is located in the middle of the first piercing portion 221, and two ends of the second flow passage 222 are respectively communicated with the cavity 211 and the first flow passage 212. The first piercing portion 221 is used to pierce the bottom of the capsule 200 so that the first flow channel 212, the second flow channel 222 and the interior of the capsule 200 are communicated to allow the beverage brewed in the capsule 200 to flow from the second flow channel 222 to the first flow channel 212 and then to be discharged to the outside through the water outlet 213.
The brewing chamber assembly 20 is provided with a first elastic member 23, the first elastic member 23 is arranged in the cavity 211 of the brewing housing 21, the first elastic member 23 can be elastically abutted to the bottom of the capsule 200, and the first elastic member 23 is used for ejecting the waste capsule 200 after brewing out of the cavity 211 of the brewing housing 21.
The middle part of the extraction base 22 is provided with a containing hole 223, one end of the first elastic member 23 is installed at the bottom of the containing hole 223, the other end of the first elastic member is far away from the bottom of the containing hole 223 compared with the tail end of the first piercing part 221, and the first elastic member 23 can be completely contained in the containing hole 223 when being elastically compressed.
Specifically, during movement of the brew head assembly 30 from the first position to the second position, the capsule 200 enters the chamber 211 of the brew housing 21 and its bottom portion presses the first elastic member 23, so that the first elastic member 23 is elastically compressed towards the bottom portion of the receiving hole 223, while the first piercing portion 221 pierces the bottom portion of the capsule 200, so that the second flow passage 222 communicates with the interior of the capsule 200; during the movement of the brewing head assembly 30 from the second position to the first position, the first elastic member 23 resumes the elastic deformation and ejects the waste capsule 200 in a direction away from the extraction base 22, so that the waste capsule 200 is separated from the first piercing portion 221 and ejected out of the cavity 211, and then falls out of the cavity 101 of the housing 10 through the second opening 103.
In a specific embodiment, the first elastic member 23 may be detachably mounted in the accommodating hole 223 through the fixing member 231, and the fixing member 231 sequentially penetrates through the first elastic member 23, the extraction base 22 and the brewing housing 21 to fixedly connect the first elastic member 23 and the extraction base 22 to the brewing housing 21, wherein the fixing member 231 may be a screw. In the present embodiment, the first elastic member 23 is a compression spring, however, the first elastic member 23 may be other elements having elastic restoring capability, such as a leaf spring.
Further, the brewing chamber assembly 20 is further provided with a first ejection assembly 24, the first ejection assembly 24 is disposed on the outer wall of the brewing housing 21, the first ejection assembly 24 can be elastically abutted against the rim of the capsule 200, and the first ejection assembly 24 is used for ejecting the waste capsule 200 after brewing out of the cavity 211 of the brewing housing 21.
The first ejection assembly 24 includes a first ejection member 241 and a second elastic member 242.
The brewing housing 21 is provided with a clamping groove 214 for accommodating the first ejection piece 241 and the second elastic piece 242, and the clamping groove 214 is positioned on the outer side wall of the brewing housing 21. The first ejection member 241 is slidably embedded in the clamping groove 214, and the first ejection member 241 can slide along the clamping groove 214 relative to the brewing housing 21, so that the first ejection member 241 can be completely accommodated in the clamping groove 214 or partially extend out of the opening edge of the brewing housing 21. The second elastic member 242 is elastically disposed in the clamping groove 214, one end of the second elastic member 242 abuts against an end sidewall of the clamping groove 214, and the other end of the second elastic member 242 abuts against the first ejection member 241.

(II), a preparation and drinking stage: through the water inlet channel 313 and the second piercing portion 321 piercing the perforation of the capsule 200, high-pressure hot water is injected into the interior of the capsule 200, so that the powdered beverage of the capsule 200 is fused into a fluid hot beverage, which can be released outwards through the second flow channel 222, the first flow channel 212, the water outlet 213 and the water outlet nozzle 11 in sequence.
(III), ending stage: turning the trigger 61 in the opposite direction drives the piston 31 from the second position to the first position while the brewed waste capsule 200 falls out of the chamber 211 of the brewing housing 21, as follows.
The pulling handle 61 is turned in the opposite direction, so that the piston 31 moves away from the brewing housing 21 by the guiding structure, and the transmission assembly 50 drives the capsule hook 42 to rotate 180 ° in the second direction under the driving of the piston 31 until the bearing portion 422 faces the guiding through groove 111 of the guiding groove body 11.
During the movement of the piston 31 from the first position to the second position, the first elastic member 23 and the first ejection assembly 24 resume elastic deformation and together eject the waste capsule 200 out of the chamber 211, while the second ejection assembly 35 resumes elastic deformation and separates the second piercing portion 331 from the top of the waste capsule 200, so that the waste capsule 200 falls out of the cavity 101 of the housing 10 from the second outlet 103.
The embodiment of the invention also provides a beverage machine comprising the brewing device 100, and further comprising a water tank device connected with the brewing device 100, wherein the water tank device is used for providing water required for brewing the beverage to the brewing device 100.
