[0047] A fully automatic coffee machine is a device that can automatically process and make coffee drinks. A fully automatic coffee machine usually includes a storage system, a grinding system, a water treatment system, a water heating system, a brewing system, a control system, and the like. Among them, the brewing system, as one of the cores of the fully automatic coffee machine, is used to extract coffee, that is, to extract the flavor compounds, oils, and aroma components in the coffee powder into the water to form a coffee drink.

The disassembly and assembly process of the above-mentioned brewing chamber 3 is exemplified as follows: when the brewing chamber 3 is installed, the brewing chamber 3 is moved into the receiving space 14 so that the first clip 332 and the second clip 333 are respectively snapped into the first clip 11 and the second clip 11; when the brewing chamber 3 is disassembled, the first gripping portion 3311 and the second gripping portion 3312 are first held at the same time so that the first clip 332 and the second clip 333 are deformed at the same time and respectively detached from the first clip 11 and the second clip 11, and then the brewing chamber 3 is moved into the receiving space 14.

[0052] It should be noted that when the buckle assembly 33 is engaged with the bayonet 11, the portion of the second piston 32 extending out of the brewing chamber 311 is connected to the portion of the first piston 22 extending out of the cylinder chamber 211, including but not limited to one or more of the connection modes such as snap connection, plug connection, screw connection, clamping, magnetic attraction and hook connection.

When the buckle assembly 33 is clamped to the bayonet 11, the U-shaped portion of the U-shaped insert block 321 extends from the U-shaped opening of the U-shaped slot 221, so that the insert block 321 is plugged into the slot 221. In the above manner, the slot 221 and the insert block 321 are both U-shaped, which can increase the area of ​​the slot 221 and the insert block 321 for plugging and limiting, and help to improve the connection stability between the portion of the second piston 32 extending out of the brewing chamber 311 and the portion of the first piston 22 extending out of the cylinder chamber 211.

The limiting rod 532 follows the screw rod 531 to move along the limiting groove 511.

[0062] Through the above manner, the screw rod 531 can be moved relative to the transmission frame 51 , and the screw rod 531 does not rotate relative to the transmission frame 51 .

[0063] For the above transmission mechanism 5, please refer to Figures 9 to 12 The transmission mechanism 5 includes a first limit switch 54, which is arranged on the second bracket 4 and is close to one end of the limit slot 511. The first limit switch 54 is used to abut the limit rod 532 when the limit rod 532 moves along the limit slot 511 toward one end of the limit slot 511 to the limit position. In addition, the transmission mechanism 5 includes a second limit switch 55, which is arranged on the second bracket 4 and is close to the other end of the limit slot 511. The second limit switch 55 is used to abut the limit rod 532 when the limit rod 532 moves along the limit slot 511 toward the other end of the limit slot 511 to the limit position. It should be noted that the limit position here refers to the position where the limit rod 532 abuts against one end or the other end of the limit slot 511.

[0064] In the above manner, when the limit rod 532 moves to abut the first limit switch 54 or the second limit switch 55, the first limit switch 54 and the second limit switch 55 can be triggered in time to feedback the start / stop signal to the drive component 52, thereby preventing the drive component 52 from idling at the extreme position and reducing the probability of damage to the drive component 52.

[0065] For the first bracket 1, the second bracket 4 and the transmission mechanism 5, please refer to Figures 9 to 11 The first bracket 1 is provided with a second protrusion 18, and the second protrusion 18 is located on a side of the rotating portion 16 away from the first protrusion 17.

The transmission mechanism 5 includes an elastic member 56, one end of the elastic member 56 is connected to the second protrusion 18, and the other end of the elastic member 56 is connected to the third protrusion 44. The elastic member 56 is used for compressing and deforming when the first bracket 1 swings from the first preset angle X to the second preset angle Y.

[0066] In the above manner, when the first bracket 1 swings from the first preset angle X to the second preset angle Y, the elastic member 56 is compressed and deformed and generates an elastic restoring force, so that the elastic member 56 plays a buffering effect in the process of the first bracket 1 swinging from the first preset angle X to the second preset angle Y, thereby avoiding a large impact force caused by a sudden stop when the first bracket 1 swings quickly to the end position.

The first gear 521, the second gear 522 and the third gear 523 are meshed in sequence. The first gear 521 is threadedly connected to one end of the screw rod 531, and the third gear 523 is drivingly connected to the motor 524.

[0068] It can be understood that the driving component 52 includes but is not limited to a gear set structure.

The turbine and the worm are both rotatably arranged on the transmission frame 51. The turbine and the worm are meshed. The turbine is threadedly connected to one end of the screw 531, and the worm is drivingly connected to the motor 524.

[0069] In the above manner, compared with the structure in which the driving component 52 is a motor 524 and a worm gear, the structure in which the driving component 52 is a motor 524 and a gear set can save space, reduce the overall volume of the brewing system 100, and contribute to the miniaturization development of the brewing system 100.

[0074] Through the above method, the brewing liquid can enter the brewing cavity 311.

[0075] It should be noted that when the first bracket 1 swings between the first preset angle X and the second preset angle Y relative to the second bracket 4, the portion of the first channel 15 that passes through the second bracket 4 swings relative to the second bracket 4 to avoid interference.

[0076] For the above brewing chamber 3, see Fig.14 The brewing chamber 3 includes a water dividing network 36, which is arranged on the top of the second piston 32.
