[0028] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] See Figures 1 - 15 , An extraction powder cup applied to a semi-automatic coffee machine. The semi-automatic coffee machine includes a machine body 10. A bean grinding assembly 20 for supplying coffee powder to the extraction powder cup 50 is provided inside the machine body 10. A weighing module 40 for connecting the extraction powder cup 50 is provided at the powder outlet of the bean grinding assembly 20. The machine body 10 is provided with an extraction and powder pressing module 30 for pressing the powder in the extraction powder cup 50 and performing extraction.

[0030] In the present utility model, the semi-automatic coffee machine is provided with a controller for the bean grinding assembly 20, the weighing module 40, and the extraction and powder pressing module 30.

[0031] Based on the above embodiments, the working principle of the present utility model is as follows: When feeding powder, the extraction powder cup 50 is connected to the weighing module 40, and the bean grinding assembly 20 supplies coffee powder into the extraction powder cup 50. During this process, the weighing module 40 detects the real-time change of the extraction powder cup 50 to control the accurate amount of coffee powder in the extraction powder cup 50.

[0032] When pressing the powder and extracting, the extraction powder cup 50 filled with coffee powder is installed on the extraction and powder pressing module 30 to compact and distribute the powder in the extraction powder cup 50 through the extraction and powder pressing module 30. After the powder pressing is completed, extraction is performed through the extraction and powder pressing module 30, and the extracted coffee liquid flows downward from the extraction powder cup 50.

[0033] See Figures 4 to 6 , The weighing module 40 includes a fixed frame 410 provided inside the machine body 10. A weighing sensor 420 is installed on the fixed frame 410. A suspension arm 430 is installed at the sensing end of the weighing sensor 420. An installation platform 440 for connecting with the extraction powder cup 50 is provided at one end of the suspension arm 430 away from the weighing sensor 420. The installation platform 440 is detachably connected to the extraction powder cup 50, and a communication port 441 for communicating the bean grinding assembly 20 and the extraction powder cup 50 is provided on the installation platform 440.

[0034] The extraction powder cup 40 is installed on the installation platform 440, and its weight acts on the sensing end of the weighing sensor 420 through the boom 430. The weighing sensor 420 can detect the weight in real time to control the amount of powder delivered by the grinding component 20 to the extraction powder cup 50 at a single time. The principle is that the weighing sensor 420 transmits weight data to the controller in real time, and at the same time, the controller is used to control the start and stop of the grinding component, so as to stop supplying powder to the extraction powder cup by controlling the shutdown of the grinding component.

[0035] See Figure 6 , the installation platform 440 is magnetically connected to the extraction powder cup 50.

[0036] Furthermore, a plurality of first magnets 450 are arranged on the installation platform 440, and second magnets 70 are arranged at positions corresponding to the first magnets 450 on the extraction powder cup 50. When the extraction powder cup 50 is assembled to the installation platform 440, the second magnets 70 are attracted and fixed to the first magnets 450.

[0037] See Figure 2 , a powder delivery pipe fitting 60 is arranged in the communication port 441. When the extraction powder cup 50 is installed on the installation platform 440, the lower end of the powder delivery pipe fitting 60 is inserted into the interior of the extraction powder cup 50. The arrangement of the powder delivery pipe fitting 60 can prevent powder leakage caused by a gap at the connection between the extraction powder cup 50 and the installation platform 440.

[0038] See Figure 7 , the extraction and powder pressing module 30 includes an installation bracket 310. An installation cavity 311 for installing the extraction powder cup 50 is arranged on the installation bracket 310. An elevating screw 320 that moves up and down relative to the installation bracket 310 is arranged on the installation bracket 310 above the installation cavity 311. A powder pressing head 330 is fixed to the lower end of the elevating screw 320. The interior of the elevating screw 320 is hollow and is provided with a delivery pipe 340. An extraction channel 331 communicated with the delivery pipe 340 is integrated in the powder pressing head 330. The lower end of the extraction channel 331 is open. A driving component 350 for driving the elevating screw 320 to move up or down is arranged on the installation bracket 310.

[0039] Based on the above embodiment of the extraction and powder pressing module 30, during powder pressing, the driving component 350 drives the elevating screw 320 to move up or down, so as to drive the powder pressing head 330 located at the lower end of the elevating screw 320 to move downward into the extraction powder cup 50 to compact the powder in the extraction powder cup 50.

[0040] During extraction, an external supply mechanism supplies extraction water to the delivery pipe 340. After the extraction water enters the extraction channel 331, it flows downward through the extraction channel 331 into the extraction powder cup 50 for extraction.

[0041] See Figure 7 Figure 7 , the driving assembly 350 includes a driving motor 354 disposed on the mounting bracket 310. A driving gear 353 is mounted on the motor shaft of the driving motor 354. A driven gear 351 is rotatably disposed on the mounting bracket 310. The driven gear 351 is threadedly connected to the lifting screw 320. A transmission gear 352 is rotatably disposed on the mounting bracket 310. The driving gear 353, the transmission gear 352, and the driven gear 351 are sequentially meshed for transmission.

[0042] For the working principle of the driving assembly 350, the driving motor 354 drives the driving gear 353 to rotate, so as to drive the driven gear 351 to rotate through the transmission gear 352. When the driven gear 351 rotates, under the action of its threaded connection, it can drive the lifting screw 320 to move downward or upward relative to the mounting bracket 310. Its upward or downward movement is realized by the forward or reverse rotation of the driven gear 351.

[0043] See Figure 9 Figure 9 , a guide groove 321 is provided on the lifting screw 320, and a guide block 313 inserted into the guide groove 321 is provided on the mounting bracket 310. The cooperation between the guide block 313 and the guide groove 321 can restrict the lifting screw 320 to only move up and down relative to the mounting bracket 310 and cannot rotate, so as to realize the cooperation between the lifting screw 320 and the driven gear 351 to achieve lifting.

[0044] See Figure 8 and Figure 10 Figure 10 , the front side of the installation cavity 311 is open, and convex ribs 312 are provided on the left and right sides of the installation cavity 311. Slots 501 are provided on the left and right sides of the extraction powder cup 50. The convex ribs 312 are inserted into the slots 501.

[0045] See Figures 13 to 15 Figures 13 to 15 , the extraction powder cup 50 includes an inner cup body 500 and an outer cup body 510. The outer cup body 510 is rotatably disposed on the inner cup body 500. The upper and lower sides of the inner cup body 500 are open. An extraction seat 530 is disposed inside the inner cup body 500. The extraction seat 530 is movably disposed up and down relative to the inner cup body 500. A liquid outlet pipe 550 is provided at the bottom of the extraction seat 530. The extraction seat 530 is integrated with an extraction flow channel 540. The extraction flow channel 540 is communicated with the inner cup body 500 above the extraction seat 530. The extraction flow channel 540 is communicated with the liquid outlet pipe 550;

[0046] A lifting cup body 520 is disposed inside the outer cup body 510. The extraction seat 530 is fixedly disposed on the lifting cup body 520. The lifting cup body 520 is threadedly connected to the inner cup body 500;

[0047] A lifting guide groove 511 is provided inside the outer cup body 510, and a lifting guide block 521 inserted into the lifting guide groove 511 is provided on the lifting cup body 520.

[0048] When cleaning the powder cake, drive the lifting cup body to rotate forward. Under the action of the threaded connection, the extraction seat can be driven to move upward to push the powder cake located inside the inner cup body upward, so that the powder cake falls out of the opening above the inner cup body to the outside to achieve cleaning. After the cleaning is completed, the extraction seat is driven to reset by reversing the lifting cup body.

[0049] Usage principle of the extraction powder cup 50: The movably arranged lifting cup body 520 cooperates with the extraction seat 530, so that after the brewing is completed, by rotating the outer cup body 510, the extraction seat 530 can be driven to move upward, thereby pushing out the powder cake located inside the inner cup body 500, so as to solve the problem that it is difficult to take out the powder cake in the extraction powder cup 50 after brewing in the existing semi-automatic coffee machine.

[0050] Lifting principle of the extraction seat 530: When the outer cup body 510 is rotated, through the cooperation of the lifting guide groove 511 and the lifting guide block 521, the lifting cup body 520 can be driven to rotate. At the same time, since the lifting cup body 520 is threadedly connected to the inner cup body 500. Therefore, during rotation, the lifting cup body 520 will move up and down relative to the outer cup body 510 and the inner cup body 500. During the movement, the lifting guide block 521 also moves relative to the lifting guide groove 511, thereby driving the extraction seat 530 fixedly arranged on the lifting cup body 520 to move up and down.

[0051] Furthermore, an opening 560 is provided at the bottom of the outer cup body 510, and the liquid outlet pipe 550 is located inside the opening 560. The setting of the opening 560 can make the coffee liquid output from the liquid outlet pipe 550 drip downward into the coffee cup below.

[0052] Furthermore, a connecting seat 570 is provided at the upper part of the inner cup body 500, and the second magnet 70 is fixedly arranged on the connecting seat 570.

[0053] Furthermore, when rotating the outer cup body 510, the connecting seat 570 can be held to keep the inner cup body 500 in a fixed state and not rotate synchronously with the outer cup body 510.

[0054] See Figure 2 , the grinding component 20 includes a grinder 210, an input end of the grinder 210 is connected to a grinding bin 220, and an output end of the grinder 210 is connected to a powder delivery pipe 230.
