[0003] To meet people's diverse coffee tastes, coffee machines integrate different brewing modes. For example, a coffee machine offers both drip and capsule modes. The brewing mechanism includes a drip assembly, a piercing assembly, an extraction cup, and a capsule holder. In drip mode, hot water is introduced into the extraction cup, where it mixes with the coffee grounds to extract the liquid coffee. In capsule mode, a motor drives the piercing assembly to penetrate the coffee capsule, extracting the liquid coffee from the capsule.

[0078] Please refer to Figure 1 One embodiment of the present application provides a beverage brewing assembly, comprising a fixed bracket 200, a brewing device 300, a first drive device, and a switching device 600. When the beverage brewing assembly is used in a coffee machine, the fixed bracket 200 is disposed on the coffee machine main unit 100. For ease of description, the following uses a first direction Z, a second direction Y, and a third direction X to describe directions, with the first direction Z, the second direction Y, and the third direction X being perpendicular to each other.

[0079] The brewing device 300 is mounted on the fixing bracket 200 and has a first brewing mode and a second brewing mode.

[0080] The first driving device is mounted on the fixed bracket 200. The first driving device has a first position corresponding to the first brewing mode and a second position corresponding to the second brewing mode relative to the fixed bracket 200. When the first driving device is in the first position, it can drive the brewing device 300 to move in the first motion mode. When the first driving device is in the second position, it can drive the brewing device 300 to move in the second motion mode.

[0081] The switching device 600 is installed on the fixing bracket 200 , and when the switching device 600 moves, it can drive the first driving device to switch between the first position and the second position.

[0082] When the beverage brewing assembly described above is used in a coffee machine, the switching device 600 can be operated to switch the first drive device between a first position and a second position. When the user desires to brew coffee in the first brewing mode, the switching device 600 can be used to switch the first drive device to the first position. When the brewing device 300 is in the first brewing mode, the first drive device in the first position can drive the brewing device 300 to move in a first motion pattern. When the user desires to brew coffee in the second brewing mode, the switching device 600 can be used to switch the self-locking drive device to the second position. When the brewing device 300 is in the second brewing mode, the self-locking drive device in the second position can drive the brewing device 300 to move in a second motion pattern. When the first brewing mode is the drip mode, the first motion pattern involves the extraction cup performing periodic motion along a specific motion trajectory, thereby evenly mixing the hot water and coffee grounds, thereby facilitating uniform extraction of the coffee grounds. When the second brewing mode is the capsule mode, the second motion pattern involves the piercing assembly moving to pierce or remove the coffee capsule. Thus, the beverage brewing assembly of the present application can be switched by the switching device 600 so that the first driving device is in different working positions in different brewing modes. Thus, the first driving device can drive the brewing device 300 to move in different motion patterns in different brewing modes, facilitating the brewing device 300 to brew coffee in different brewing modes. Moreover, only one first driving device is required to control the brewing device to move in different motion patterns in different brewing modes, thereby reducing the number of driving devices and lowering costs.

[0083] In other embodiments, the beverage brewing component is not limited to being used in coffee machines, but can also be used in other beverage machines to brew other beverages (such as juice, tea).

[0084] refer to Figure 2In one embodiment, the brewing device 300 includes a drip assembly 310, a puncture assembly 320, an extraction cup 330, and a capsule holder 340. The drip assembly 310 is mounted on the fixed bracket 200. The puncture assembly 320 is mounted on the fixed bracket 200. The capsule holder 340 is detachably mounted in the extraction cup 330.

[0085] The first brewing mode is the drip mode. When the brewing device 300 is in the drip mode, the capsule holder 340 is removed from the extraction cup 330, and the first driving device drives the brewing device 300 to move in the first motion mode at the first position, so as to facilitate the extraction of coffee through the drip mode.

[0086] The second brewing mode is the capsule mode. When the brewing device 300 is in the capsule mode, the capsule holder 340 is located in the extraction cup 330, and the coffee capsule 341 is placed in the capsule holder 340. The first driving device can drive the brewing device 300 in the second position to move in the second motion mode, facilitating the extraction of coffee in the capsule mode.

[0087] refer to Figure 2 In one embodiment, the first motion mode is that the extraction cup 330 performs periodic motion along a specific motion trajectory, and the second motion mode is that the piercing assembly 320 moves relative to the fixed bracket 200 to pierce the coffee capsule 341 on the capsule rack 340 or remove it from the coffee capsule 341.

[0088] When the brewing device 300 extracts coffee powder in the drip mode, the extraction cup 330 performs periodic motion along a specific movement trajectory, thereby improving the mixing uniformity of the coffee powder and water, which is conducive to sufficient extraction.

[0089] refer to Figure 5 and Figure 6 The piercing assembly 320 is provided with a first piercing needle 321, and the capsule holder 340 is provided with a second piercing needle 342. When the brewing device 300 is in brewing mode, the piercing assembly 320 moves along the first direction Z to pierce the coffee capsule 341 on the capsule holder 340. Simultaneously, the second piercing needle 342 on the capsule holder 340 pierces the coffee capsule 341. Thus, water entering the piercing assembly 320 can enter the coffee capsule 341 through the first piercing needle 341, and after being extracted in the coffee capsule 341, the coffee liquid flows out through the second piercing needle 342. After extraction is completed, the piercing assembly 320 can be moved along the first direction Z to be removed from the coffee capsule 341.

[0090] Please refer to Figure 1 In one embodiment, the beverage brewing assembly further includes a mounting bracket 210 and a cup holder bracket 220. The mounting bracket 210 is connected to the fixed bracket 200, and the cup holder bracket 220 is disposed on the mounting bracket 210. The cup holder bracket 220 is provided with a placement groove for placing the extraction cup 330.

[0091] Specifically, the mounting bracket 210 may be located on one side of the fixed bracket 200 along the first direction Z. The cup holder bracket 220 is located on a side of the mounting bracket 210 away from the fixed bracket 200 along the first direction Z. The mounting bracket 210 includes a mounting bracket body 211 and a mounting bracket cover 212, and the cup holder bracket 220 includes a cup holder bracket body 221 and a cup holder bracket housing 222.

[0092] Please refer to Figures 3 to 6 In one embodiment, the beverage brewing assembly further includes a brewing cup sensor 334 and a capsule holder sensor 343. The brewing cup sensor 334 and capsule holder sensor 343 are each mounted on the mounting bracket 210. The brewing cup sensor 334 is used to sense whether the brewing cup 330 is placed on the cup holder bracket 220 (e.g., whether the brewing cup 330 is located within the placement slot). The capsule holder sensor 343 is used to sense whether the capsule holder 340 is located within the brewing cup 330. Based on the sensing results of the brewing cup sensor 334 and capsule holder sensor 343, the user can easily confirm whether the brewing cup 330 and capsule holder 340 are properly placed.

[0093] Specifically, refer to Figure 7 , an extraction cup sensing position 335 is provided on the extraction cup 330, and a capsule holder sensing position 344 is provided on the capsule holder 340. When the extraction cup 330 is placed on the cup holder 220, the extraction cup sensing position 335 can trigger the extraction cup sensing element 334 to generate a sensing signal, indicating that the extraction cup 330 is properly placed. When the extraction cup 330 is placed on the cup holder 220 and the capsule holder 340 is located within the extraction cup 330, the capsule holder sensing position 344 can trigger the capsule holder sensing element 343 to generate a sensing signal, indicating that the capsule holder 340 is properly placed.

[0094] In one embodiment, the beverage brewing assembly further includes a mode prompting device (not shown). When the extraction cup sensor 334 senses that the extraction cup 330 is placed on the cup holder 220, the mode prompting device can be triggered to emit a first prompting signal, thereby allowing the user to confirm that the extraction cup 330 is properly placed based on the first prompting signal. When the capsule holder sensor 343 senses that the capsule holder 340 is located within the extraction cup 330, the mode prompting device can be triggered to emit a second prompting signal, thereby allowing the user to confirm that the capsule holder 340 is properly placed based on the second prompting signal. The mode prompting device can be, for example, an audible prompting device, a visual prompting device, or a combined audible and visual prompting device.

[0095] In this way, when the user does not place the capsule holder 340 in the extraction cup 330 and the mode prompt device sends a first prompt signal, the user can confirm that the extraction cup 330 has been placed in place, and can switch the brewing device 300 to the drip mode through the switching device 600.

[0096] When the mode prompt device sends out the first prompt signal and the second prompt signal at the same time, the user can confirm that the extraction cup 330 and the capsule rack 340 are both placed in place, and can switch the brewing device 300 to the capsule mode through the switching device 600 to start brewing coffee using the capsule mode.

[0097] The extraction cup sensor 334 may be, but is not limited to, a micro switch, a reed switch, a tact switch, a Hall switch, etc. The capsule holder sensor 343 may be, but is not limited to, a micro switch, a reed switch, a tact switch, a Hall switch, etc.

[0098] Please refer to Figure 8 and Figure 9 In one embodiment, the switching device 600 includes a switching knob 610. Figures 10 to 13 One of the switch knob 610 and the first driving device is provided with a transmission slot 611 , and the other is provided with a transmission portion 430 , and the transmission portion 430 is slidably matched with the transmission slot 611 .

[0099] The switch knob 610 is rotatably connected to the fixing bracket 200 around an axis in the second direction Y. When the switch knob 610 rotates, the first driving device can be driven to switch between the first position and the second position through the sliding cooperation between the transmission part 430 and the transmission slot 611 .

[0100] When the user is operating, he only needs to turn the switching knob 610, so that the transmission part 430 can slide relatively in the transmission groove 611, and then generate a driving force between the transmission part 430 and the groove wall of the transmission groove 611, driving the first drive device to switch between the first position and the second position, thereby facilitating the switching of the position of the first drive device.

[0101] Please refer to Figures 14 to 16 In one embodiment, the switch knob 610 is provided with a transmission slot 611, and the first driving device is provided with a transmission portion 430. Figure 17 The extension direction of the transmission groove 611 surrounds the axis of the switching knob 610, and there is a position difference between the two ends of the transmission groove 611 along the axial direction of the switching knob 610 (the extension direction of the transmission groove 611 is roughly along the spiral direction). Therefore, when the switching knob 610 rotates, the groove wall of the transmission groove 611 can push the transmission part 430 to move along the transmission groove 611, thereby causing the transmission part 430 to move in the axial direction of the switching knob 610.

[0102] In other embodiments, the transmission slot may be provided on the first driving device, and the transmission portion may be provided on the switching knob.

[0103] Please refer to Figure 9In one embodiment, the first drive device includes a motor 410 and a motor bracket 420. The motor bracket 420 is movably connected to the fixed bracket 200, so that the motor bracket 420 can move relative to the fixed bracket 200. The motor 410 and the motor bracket 420 are fixedly connected so as to move synchronously. Therefore, the first drive device can be switched between the first position and the second position by the movement of the motor bracket 420 and the motor 410 relative to the fixed bracket 200.

[0104] Please refer to Figures 9 to 13 In one embodiment, the first driving device is connected to the fixed bracket 200 for rotation around the axis of the first direction Z, and the first driving device switches between the first position and the second position by rotating around the axis of the first direction Z.

[0105] Specifically, the motor bracket 420 can be rotatably connected to the fixed bracket 200 about an axis in the first direction Z. The transmission portion 430 can be provided on the motor bracket 420. In this way, when the switching knob 610 is rotated, the groove wall of the transmission groove 611 can push the transmission portion 430 to move, and the transmission portion 430 can drive the motor bracket 420 to rotate relative to the fixed bracket 200, thereby achieving switching between the first position and the second position.

[0106] In other embodiments, the first driving device and the fixed bracket may be movably connected. For example, a guide groove may be provided on the fixed bracket to guide the transmission part to move in a straight line, thereby driving the first driving device to move in translation.

[0107] Please refer to Figure 9 In one embodiment, the beverage brewing assembly further includes a rotating limit frame 230 connected to the fixed bracket 200, and the rotating limit frame 230 is provided with a limit groove 231. The switching knob 610 cooperates with the limit groove 231 to rotate around the axis of the second direction Y, thereby limiting the rotation of the switching knob 610 relative to the fixed bracket 200 around the axis of the second direction Y.

[0108] Specifically, the rotation limiter 230 is provided with a first arcuate groove, and the fixed bracket 200 is provided with a second arcuate groove. The first arcuate groove and the second arcuate groove are combined to form a circular hole, and the switch knob 610 rotates in conjunction with the circular hole. The limiter groove 231 is the first arcuate groove.

[0109] refer to Figures 10 to 13In one embodiment, the beverage brewing assembly further includes a first sensor 232 and a second sensor 233. When a switching device (such as a switching knob 610) drives the first drive device to switch to the first position, the first sensor 232 generates a sensing signal. When the switching device (such as a switching knob 610) drives the first drive device to switch to the second position, the second sensor 233 generates a sensing signal. In this way, the user can confirm whether the first drive device is switched to the correct position based on the sensing signals generated by the first and second sensors 232 and 233.

[0110] Specifically, the first sensing element 232 and the second sensing element 233 may be disposed on the rotation limiting frame 230 .

[0111] Furthermore, a switching prompt device can be configured for the beverage brewing component. When the switching device drives the first driving device to switch to the first position, the sensing signal generated by the first sensing element 232 can trigger the switching prompt device to emit a first in-position signal. When the switching device drives the first driving device to switch to the second position, the sensing signal generated by the second sensing element 233 can trigger the switching prompt device to emit a second in-position signal. Thus, the user can confirm whether the first driving device has switched to the in-position position based on the in-position signal emitted by the switching prompt device. The switching prompt device can be, for example, an audible prompt device, a light prompt device, or an integrated audible and light prompt device.

[0112] Please refer to Figure 1 In one embodiment, the beverage brewing assembly further includes a water channel device. The water channel device is mounted on the fixed bracket 200. Figure 18 、 Figure 20 、 Figure 21 The water channel device has a first water supply port 501 and a second water supply port 502. When the brewing device 300 is in the first brewing mode, it is connected to the first water supply port 501, so that the water channel device can supply water to the brewing device 300 through the first water supply port 501. When the brewing device 300 is in the second brewing mode, it is connected to the second water supply port 502, so that the water channel device can supply water to the brewing device 300 through the second water supply port 502. When the switching device 600 moves, it can drive the water channel device to move so that one of the first water supply port 501 or the second water supply port 502 is connected to the brewing device 300.

[0113] By operating the switching device 600, the water channel device is driven to move so that one of the first water supply port 501 or the second water supply port 502 is connected to the brewing device 300. When the user needs to brew coffee using the first brewing mode, the switching device 600 can be used to switch the water channel device to the first water supply port 501 to connect with the brewing device 300. The water channel device can supply water to the brewing device 300 through the first water supply port 501, so that the brewing device 300 brews coffee using the first brewing mode.

[0114] When the user needs to brew coffee using the second brewing mode, the water channel device can be switched to the second water supply port 502 to connect with the brewing device 300 through the switching device 600. The water channel device can supply water to the brewing device 300 through the second water supply port 502, so that the brewing device 300 uses the second brewing mode to brew coffee.

[0115] Furthermore, the switching device 600 can simultaneously drive the first drive device to switch position and the waterway device to switch the water supply port, which facilitates the simultaneous switching of the first drive device and the waterway device without having to switch the first drive device and the waterway device separately, thereby facilitating operation.

[0116] Specifically, the switching device 600 drives the first driving device to switch to the first position, while driving the water channel device to switch to the first water supply port 501 and connect with the brewing device 300; the switching device 600 drives the first driving device to switch to the second position, while driving the water channel device to switch to the second water supply port 502 and connect with the brewing device 300.

[0117] In one embodiment, the drip assembly 310 has a first water inlet and a first water outlet, and the first water outlet faces the mouth of the extraction cup 330 .

[0118] When the brewing device 300 is in drip mode, the first water supply port 501 is connected to the first water inlet. Thus, the water channel assembly can supply water into the drip assembly 310 through the first water supply port 501 and the first water inlet. The water then flows through the drip assembly 310 and into the extraction cup 330 from the first water outlet, thereby extracting the coffee grounds in the extraction cup 330.

[0119] When the brewing device 300 is in capsule mode, the second water supply port 502 is connected to the water inlet of the puncture component 320, so that the water channel device can supply water into the puncture component 320 through the second water supply port 502 and the water inlet of the puncture component 320.

[0120] refer to Figure 3 In one embodiment, the drip assembly 310 includes an inner annular wall 311, an outer annular wall 312, and an end plate 313 connecting the inner and outer annular walls 311, 312. The inner and outer annular walls 311, 312, and the end plate 313 thereby enclose an annular cavity. A first water outlet is provided on the end plate 313. A first water inlet communicates with the annular cavity. The first water supply port 501 and the first water inlet can be connected via a pipeline, allowing water to flow into the annular cavity sequentially through the first water supply port 501, the pipeline, and the first water inlet. The water then flows out of the first water outlet provided on the end plate 313 and into the extraction cup 330. The annular cavity is axially oriented along a first direction Z. The piercing assembly 320 is movably disposed in the space surrounding the inner annular wall 311 along the first direction Z. This facilitates the arrangement of the drip assembly 310 and the piercing assembly 320 without affecting the movement of the piercing assembly 320.

[0121] refer to Figure 3 In one embodiment, the inner and outer annular walls 311 and 312, at ends distal from the end plate 313, form a first water inlet, which is covered by the fixed bracket 200. The fixed bracket 200 is provided with a liquid passage that communicates with the first water inlet. This passage is connected to the first water supply port 501 via a pipeline. Thus, water from the first water supply port 501 can enter the annular cavity sequentially through the pipeline, the liquid passage, and the first water inlet.

[0122] In one embodiment, the second water supply port 502 may be connected to the water inlet of the puncture assembly 320 via a pipeline, so that water is supplied to the puncture assembly 320 through the pipeline.

[0123] Please refer to Figure 18 and Figure 19 In one embodiment, the water channel device includes a water diversion sleeve 510 and a water diversion rotating member 520. The water diversion sleeve 510 is fixed to the fixed bracket 200, and a water inlet interface 511 is provided at one axial end of the water diversion sleeve 510 for accessing an external water source.

[0124] The water-dividing rotating member 520 is located within the water-dividing sleeve 510. The outer surface of the water-dividing rotating member 520 is in sealed engagement with the inner surface of the water-dividing sleeve 510. One axial end of the inner cavity of the water-dividing rotating member 520 is connected to the water inlet port 511, allowing water from an external source to enter the inner cavity of the water-dividing rotating member 520 through the water inlet port 511. Because the outer surface of the water-dividing rotating member 520 is in sealed engagement with the inner surface of the water-dividing sleeve 510, water that enters the inner cavity of the water-dividing rotating member 520 is prevented from escaping between the outer surface of the water-dividing rotating member 520 and the inner surface of the water-dividing sleeve 510.

[0125] A first water diversion port 521 communicating with the inner cavity is provided on the sidewall of the water diversion rotating member 520. The first and second water supply ports 501, 502 are spaced apart along the circumference of the water diversion sleeve 510 on the sidewall of the water diversion sleeve 510. Movement of the switching device 600 drives the water diversion rotating member 520 to rotate about its own axis, selectively connecting the first water diversion port 521 to either the first or second water supply port 501, 502.

[0126] like Figure 21 As shown, the switching device 600 drives the water-dividing rotating member 520 to rotate around its own axis so that the first water-dividing port 521 is connected to the first water supply port 501. Then, the water entering the inner cavity of the water-dividing rotating member 520 can flow to the first water supply port 501 through the first water-dividing port 521. Figure 20 As shown, the switching device 600 drives the water diversion rotating member 520 to rotate around its own axis so that the first water diversion port 521 is connected to the second water supply port 502 , and the water entering the inner cavity of the water diversion rotating member 520 can flow to the second water supply port 502 through the first water diversion port 521 .

[0127] It can be seen that through the water diversion device of this embodiment, it is only necessary for the switching device 600 to drive the water diversion rotating member 520 to rotate, so that the first water diversion port 521 can be selectively connected to the first water supply port 501 or the second water supply port 502, thereby switching the water supply to the brewing device 300 when switching different brewing modes.

[0128] Please refer to Figures 19 to 21 In one embodiment, the waterway device includes a water diversion sealing ring 530. The water diversion sealing ring 530 is located between the outer circumference of the water diversion rotating member 520 and the inner circumference of the water diversion sleeve 510, and seals with the water diversion rotating member 520 and the water diversion sleeve 510, thereby improving the sealing reliability between the outer circumference of the water diversion rotating member 520 and the inner circumference of the water diversion sleeve 510.

[0129] The water-dividing sealing ring 530 is fixedly connected to the water-dividing rotating member 520. The water-dividing sealing ring 530 is provided with a second water-dividing port 531 radially connected to the first water-dividing port 521. In this way, when the water-dividing rotating member 520 rotates, the water-dividing sealing ring 530 rotates synchronously therewith, so that the first water-dividing port 521 is connected to the first water supply port 501 through the second water-dividing port 531, or the first water-dividing port 521 is connected to the second water supply port 502 through the second water-dividing port 531. In this embodiment, the water-dividing sealing ring 530 is used to improve the sealing reliability between the outer circumference of the water-dividing rotating member 520 and the inner circumference of the water-dividing sleeve 510, while the first water-dividing port 521 can still be connected to the first water supply port 501 or the second water supply port 502.

[0130] In one embodiment, the water-dividing sealing ring 530 is provided with a sealing rib located outside the second water-dividing port 531. The sealing rib is sealed with the inner surface of the water-dividing sleeve 510, thereby preventing water from the first water-dividing port 521 from flowing through the second water-dividing port 531 into the space between the inner surface of the water-dividing sleeve 510 and the outer surface of the water-dividing rotating member 520, further improving the sealing between the outer circumferential surface of the water-dividing rotating member 520 and the inner circumferential surface of the water-dividing sleeve 510.

[0131] refer to Figure 21 In one embodiment, the sealing rib includes a first rib segment 532 and a second rib segment 533. The second water diversion port 531 is located between the first rib segment 532 and the second rib segment 533 along the circumference of the water diversion sealing ring 530. The arc distance between the first rib segment 532 and the second rib segment 533 is a first arc distance L1, and the arc distance between the first water supply port 501 and the second water supply port 502 is a second arc distance L2. The first arc distance L1 is smaller than the second arc distance L2.

[0132] Since the first arc distance L1 is smaller than the second arc distance L2, when the water-dividing sealing ring 530 rotates with the water-dividing rotating member 520, the second water-dividing port 531 can only be connected to one of the first water supply port 501 and the second water supply port 502, thereby enabling the brewing device 300 to operate in one of the first brewing mode or the second brewing mode, and preventing the second water-dividing port 531 from being connected to the first water supply port 501 and the second water supply port 502 at the same time.

[0133] Please refer to Figure 18 In one embodiment, the switching device 600 includes a switching knob 610. The switching knob 610 is rotatably connected to the fixing bracket 200 about an axis in the second direction Y. Rotation of the switching knob 610 drives the water diversion rotating member 520 to rotate about its own axis, thereby switching the water supply port of the waterway device through rotation of the switching knob 610.

[0134] Furthermore, when the switching mechanism 610 is rotated to switch the first drive mechanism to the first position, the first water supply port 501 of the waterway assembly communicates with the brewing mechanism 300 (specifically, the first water inlet of the drip assembly 310). When the switching mechanism 610 is rotated to switch the first drive mechanism to the second position, the second water supply port 502 of the waterway assembly communicates with the brewing mechanism 300 (specifically, the water inlet of the piercing assembly 320). In this way, the switching mechanism 610 simultaneously switches the first drive mechanism and the waterway assembly, facilitating simultaneous switching of the first drive mechanism and the waterway assembly, eliminating the need to switch the first drive mechanism and the waterway assembly separately, thus facilitating operation.

[0135] In one embodiment, the switching device 600 is connected to the end of the water-dividing rotating member 520 that is away from the water inlet interface 511 by means of gear transmission.

[0136] Specifically, please refer to Figure 18 A first switching gear 612 is provided at one end of the switching knob 610, and a second switching gear 523 is provided at one end of the water-dividing rotating member 520. The first switching gear 612 meshes with the second switching gear 523. Therefore, when the switching knob 610 is rotated, the first switching gear 612 rotates synchronously, driving the second switching gear 523 to rotate, and thus the water-dividing rotating member 520 and the second switching gear 523 rotate synchronously. The switching knob 610 and the first switching gear 612 are coaxially arranged. The water-dividing rotating member 520 and the second switching gear 523 are coaxially arranged.

[0137] In other embodiments, the switching device and the water-dividing rotating member may also be driven in other ways.

[0138] refer to Figures 20 to 21In one embodiment, the end of the water-dividing rotating member 520 that faces away from the water inlet interface 511 is located outside the water-dividing sleeve 510 and is provided with a sensing protrusion 522. When the switching device 600 drives the water-dividing rotating member 520 to rotate until the first water diversion port 521 is connected to the first water supply port 501, the sensing protrusion 522 can trigger the first sensing member 232 to generate a sensing signal. When the switching device 600 drives the water-dividing rotating member 520 to rotate until the first water diversion port 521 is connected to the second water supply port 502, the sensing protrusion 522 can trigger the second sensing member 233 to generate a sensing signal. In this embodiment, by providing the sensing protrusion 522 on the water-dividing rotating member 520, it is easy to trigger the first sensing member 232 and the second sensing member 233 to generate a sensing signal. The user can confirm whether the waterway device has been switched into place based on the sensing signals generated by the first sensing member 232 and the second sensing member 233.

[0139] Furthermore, a switching prompt device can be configured for the beverage brewing component. When the switching device 600 drives the water diversion rotating member 520 to rotate until the first water diversion port 521 is connected to the first water supply port 501, the sensing signal generated by the first sensing member 232 can trigger the switching prompt device to emit a first in-position signal. When the switching device 600 drives the water diversion rotating member 520 to rotate until the first water diversion port 521 is connected to the second water supply port 502, the sensing signal generated by the second sensing member 233 can trigger the switching prompt device to emit a second in-position signal. Thus, the user can confirm whether the water channel device has been switched to the in-position according to the in-position signal emitted by the switching prompt device. The switching prompt device can be, for example, an audible prompt device, a visual prompt device, or an integrated audible and visual prompt device.

[0140] The first sensing element 232 may be, but is not limited to, a micro switch, a reed switch, a tact switch, a Hall switch, etc. The second sensing element 233 may be, but is not limited to, a micro switch, a reed switch, a tact switch, a Hall switch, etc.

[0141] refer to Figures 10 to 13 In one embodiment, the beverage brewing assembly includes a first transmission gear 441 and a second transmission gear 442. When the first transmission gear 441 rotates, it can drive the brewing device 300 to move according to the first motion mode. When the second transmission gear 442 rotates, it can drive the brewing device 300 to move according to the second motion mode.

[0142] The output end of the first driving device has a driving gear 440. When the first driving device is in the first position, the driving gear 440 meshes with the first transmission gear 441, thereby driving the brewing device 300 to move in the first motion mode via the first transmission gear 441. When the first driving device is in the second position, the driving gear 440 meshes with the second transmission gear 442, thereby driving the brewing device 300 to move in the second motion mode via the second transmission gear 442.

[0143] Specifically, the first transmission gear 441 is used to drive the extraction cup 330 to perform periodic motion along a specific movement trajectory. The second transmission gear 442 is used to move the piercing assembly 320 along the first direction Z to pierce the coffee capsule 341 on the capsule holder 340 or remove the coffee capsule 341 from the capsule holder 340.

[0144] In the above-described embodiment of the present application, rotation of the switch knob 610 allows the first drive device to switch between the first position and the second position while simultaneously driving one of the first water supply port or the second water supply port of the waterway device to connect with the brewing device. This means that the switching of the first drive device and the waterway device is achieved simultaneously by operating the switch knob 610, which is very convenient. Furthermore, based on the sensing signals from the first sensor 232 and the second sensor 233, the user can determine whether the first drive device and the waterway device are switched into position, and can also determine whether the waterway device is switched into position.

[0145] Please refer to Figure 1 An embodiment of the present application provides a coffee machine, comprising a main unit 100 and a beverage brewing assembly according to any one of the above embodiments, wherein a fixing bracket 200 is installed on the main unit 100 .

[0146] Please refer to Figure 22 and Figure 23 One embodiment of the present application provides a beverage brewing assembly, comprising an extraction cup 330 and a first drive device. The first drive device is connected to the extraction cup 330 and is capable of driving the extraction cup 330 to perform periodic motion along a specific movement trajectory. When the beverage brewing assembly is used in a coffee machine, the first drive device is mounted on the main unit 100 of the coffee machine.

[0147] Because the first drive device can drive the extraction cup 330 to perform periodic motion along a specific trajectory, the position of the extraction cup 330 along the specific trajectory can be periodically changed, thereby causing the extraction cup 330 to oscillate periodically along the specific trajectory. After the hot water enters the extraction cup 330, the first drive device drives the extraction cup 330 to oscillate periodically along the specific trajectory, thereby evenly mixing the hot water and coffee grounds, thereby facilitating uniform extraction of the coffee grounds.

[0148] Specifically, the first motion mode is that the extraction cup 330 performs periodic motion along a specific motion trajectory. When the first driving device is in the first position, the extraction cup 330 performs periodic motion along the specific motion trajectory.

[0149] In other embodiments, the beverage brewing component is not limited to being used in coffee machines, but can also be used in other beverage machines to brew other beverages (such as juice, tea).

[0150] Please refer to Figure 22 and Figure 23In one embodiment, the beverage brewing assembly further includes a fixed bracket 200 and a mounting bracket 210. When the beverage brewing assembly is used in a coffee machine, the fixed bracket 200 is mounted on the main unit 100, the first driving device is mounted on the fixed bracket 200, and the mounting bracket 210 is used to mount the extraction cup 330. The first driving device is used to drive the mounting bracket 210 to perform periodic motion along a specific movement trajectory, thereby causing the extraction cup 330 to perform periodic motion along the specific movement trajectory synchronously with the mounting bracket 210. The fixed bracket 200 facilitates the installation of the first driving device, and the mounting bracket 210 facilitates the first driving device to drive the extraction cup 330 to move.

[0151] Specifically, the first driving device is used to drive the mounting bracket 210 to perform periodic motion along a specific movement trajectory when in the first position.

[0152] Recombination Figure 24 and Figure 25 In one embodiment, the beverage brewing assembly further includes at least two eccentric shafts 450 parallel to the first direction. The number of eccentric shafts 450 can be two, three, or more. The first direction is the axial direction of the eccentric shafts 450. The at least two eccentric shafts 450 are spaced apart from each other in a direction perpendicular to the first direction. The eccentric shafts 450 include a first end 451 and a second end 452 eccentrically disposed relative to the first end 451.

[0153] The first end 451 of each eccentric shaft 450 is rotatably connected to the fixed bracket 200 around its own axis, and the second end 452 of each eccentric shaft 450 is rotatably connected to the mounting bracket 210 around its own axis. The first driving device is used to drive the first end 451 of the eccentric shaft 450 to rotate around its own axis.

[0154] When the first drive device drives the first end 451 of any eccentric shaft 450 to rotate about its axis, the second end 452 of that eccentric shaft 450 moves about the first end 451, driving the mounting bracket 210 to move. Because the first end 451 of each eccentric shaft 450 is rotatably connected to the fixed bracket 200 about its axis, and the second end 452 of each eccentric shaft 450 is rotatably connected to the mounting bracket 210 about its axis, the first end 451 of each eccentric shaft 450 rotates about its axis relative to the fixed bracket 200, while the connection points between the mounting bracket 210 and the second end 452 of each eccentric shaft 450 each perform circular motion of the same radius around the axis of their corresponding first end 451. Therefore, according to the law of translational motion of a rigid body, any point on the mounting bracket 210 undergoes translational motion along a circular trajectory. That is, in this embodiment, the extraction cup 330 periodically oscillates along the circular trajectory with the mounting bracket 210, thereby evenly mixing the coffee grounds and hot water.

[0155] In other embodiments, the extraction cup may also oscillate according to other motion rules, such as periodic cyclic oscillation along an elliptical trajectory, or plane-parallel motion.

[0156] refer to Figure 25 In one embodiment, a radial distance b between the axis center of the first end 451 and the axis center of the second end 452 of the eccentric shaft 450 is greater than or equal to 1 mm and less than or equal to 30 mm. Thus, the radius of any point on the extraction cup 330 when moving along a circular trajectory is 1 mm to 30 mm, resulting in an appropriate oscillation amplitude, which can effectively drive the extraction cup 330 to mix the coffee powder and hot water.

[0157] refer to Figures 23 to 25 In one embodiment, the first end 451 is rotatably connected to the fixed bracket 200 via a first bearing 453, and the second end 452 is rotatably connected to the mounting bracket 210 via a second bearing 454, so that the first end 451 can move smoothly relative to the fixed bracket 200 and the second end 452 can move smoothly relative to the mounting bracket 210.

[0158] Please combine Figures 22 to 24 The beverage brewing assembly further includes a first transmission gear 441, which is configured to drive the first end 451 of the eccentric shaft 450 to rotate about its own axis. The output end of the first drive device includes a driving gear 440, which is configured to mesh with the first transmission gear 441. When the first drive device is in the first position, the driving gear 440 meshes with the first transmission gear 441.

[0159] In this embodiment, the driving gear 440 is directly engaged with the first transmission gear 441 , so that when the driving gear 440 at the output end of the first driving device rotates, it can drive the first transmission gear 441 to rotate, and further drive the first end 451 of the eccentric shaft 450 to rotate.

[0160] In one embodiment, the first driving device includes a motor 410 , and the driving gear 440 is coaxially connected to the output shaft of the motor 410 , so that when the output shaft of the motor 410 rotates, the driving gear 440 is driven to rotate synchronously.

[0161] In other embodiments, the first driving device and the first end of the eccentric shaft 450 may be transmitted via other transmission mechanisms.

[0162] In one embodiment, the first transmission gear 441 is coaxially connected to the first end 451 of the eccentric shaft 450 .

[0163] In one embodiment, the first transmission gear 441 is provided with a transmission hole, which is a non-circular hole. The first end 451 of the eccentric shaft 450 is adapted to the transmission hole. In this way, when the first transmission gear 441 rotates, it can drive the first end 451 of the eccentric shaft 450 to rotate coaxially.

[0164] In one embodiment, the cup holder bracket 220 is provided with a locking member, and the extraction cup 330 is provided with a matching structure. When the extraction cup 330 is placed on the cup holder bracket 220 , the locking member and the matching structure can be locked and matched, so that the extraction cup 330 is securely placed in the cup holder bracket 220 .

[0165] In one embodiment, the locking member is a locking rod extending in a first direction, and the mating structure is a through-hole extending in the first direction. The beverage brewing assembly includes a self-locking drive device disposed on the cup holder bracket 220. The self-locking drive device drives the locking rod to move in the first direction, thereby inserting or removing the locking rod from the through-hole, thereby locking or releasing the locking rod from the through-hole.

[0166] In other embodiments, the locking member and the matching structure may also be in other forms, such as magnetic components that can be attracted to each other.

[0167] An embodiment of the present application provides a coffee machine, comprising a main unit 100 and a beverage brewing assembly according to any one of the above embodiments, wherein the first driving device is installed on the main unit 100.

[0168] Combine Figure 26 and Figure 27 The coffee machine of one embodiment of the present application has a puncture mechanism. The puncture mechanism includes: a fixed bracket 200, a first drive device, a puncture assembly 320, a rotary transmission member 461, and a translation transmission member 462. The fixed bracket 200 is used to be fixedly connected to the main unit 100 of the coffee machine.

[0169] The first drive device is mounted on the fixed support 200 and is used to drive the rotary transmission member 461 to rotate about its own axis. The rotary transmission member 461 is movably connected to the translational transmission member 462 and is capable of converting its own rotational motion into the translational motion of the translational transmission member 462. The translational transmission member 462 is fixedly connected to the piercing assembly 320 and is used to drive the piercing assembly 320 to move relative to the fixed support 200, thereby piercing the piercing assembly 320 into or removing it from the coffee capsule in a first direction. The first direction is the direction in which the piercing assembly 320 pierces or removes the coffee capsule.

[0170] When the first drive mechanism is in the second position, it drives the rotary transmission member 461 to rotate about its own axis, converting the rotary motion of the rotary transmission member 461 into the translational motion of the translational transmission member 462. The translational transmission member 462 then drives the piercing assembly 320, to which it is fixed, to translate synchronously. The piercing assembly 320 then moves relative to the fixed support 200 in the first direction to pierce the coffee capsule. Alternatively, after the coffee capsule is extracted, the piercing assembly 320 moves relative to the fixed support 200 in the first direction to remove the coffee capsule. In this manner, the first drive mechanism automatically drives the piercing assembly 320 to move, eliminating the need for manual operation. Furthermore, by converting the rotary motion of the rotary transmission member into the translational motion of the translational transmission member 462, the piercing assembly 320 moves in translation. This occupies less space than a lever-type mechanism, facilitating miniaturization of the coffee machine.

[0171] In one embodiment, one of the rotation transmission member 461 and the translation transmission member 462 has an internal thread and the other has an external thread, and the internal thread cooperates with the external thread, thereby driving the translation transmission member 462 to translate through thread transmission.

[0172] In the embodiment of the present application, the rotation transmission member 461 has an external thread, and the translation transmission member 462 has an internal thread.

[0173] In other embodiments, the rotation transmission member may have an internal thread, and the translation transmission member may have an external thread.

[0174] refer to Figure 27 In one embodiment, a guide structure 201 is provided on the fixed bracket 200, and the puncture component 320 is movably matched with the guide structure 201 along a first direction. Through the guidance of the guide structure 201, the moving direction of the puncture component 320 can be ensured to be accurate and stable.

[0175] In particular, when the rotating transmission member 461 and the translation transmission member 462 are both threaded transmissions, when the rotating transmission member 461 rotates, since the puncture assembly 320 can only move along the first direction, the translation transmission member 462 connected to the puncture assembly 320 is limited to move along the first direction, thereby effectively ensuring that the translation transmission member 462 performs translational movement under the action of the threaded transmission.

[0176] refer to Figure 27 In one embodiment, the guide structure 201 is a guide groove extending along the first direction.

[0177] In other embodiments, the guide structure may also be a guide portion, and a guide groove cooperating with the guide portion is provided on the puncture assembly 320, thereby also being able to guide the puncture assembly 320 to move along the first direction.

[0178] refer to Figure 26 and Figure 27 In one embodiment, the puncture mechanism further includes a gear assembly, which includes a gear or multiple gears meshing with each other, one of the gears in the gear assembly is coaxially connected to the rotating transmission member 461, and the first driving device is used to drive any gear in the gear assembly to rotate when in the second position.

[0179] exist Figure 26 and Figure 27 In the illustrated embodiment, the gear assembly includes a first gear 471 and a second gear 472 that mesh with each other. The second gear 472 is coaxially connected to the rotating transmission member 461. When the first drive device is in the second position, it is used to drive the first gear 471 to rotate, thereby driving the first gear 472 and the rotating transmission member 461 to rotate.

[0180] refer to Figure 26 In one embodiment, the puncture mechanism further includes a transmission bracket cover 470, which is fixed to the fixed bracket 200 and located on the side of the puncture assembly 320 facing away from the coffee capsule, and the rotating transmission member 461 is rotatably connected to the transmission bracket cover 470.

[0181] In one embodiment, the puncture mechanism further includes a second transmission gear 442, which is used to drive any gear in the gear assembly to rotate. The output end of the first drive device includes a driving gear 440. When the first drive device is in the second position, the driving gear 440 engages with the second transmission gear 442, thereby driving any gear in the gear assembly to rotate via the second transmission gear 442. The second transmission gear 442 can be coaxially connected to the first gear 471 via a transmission shaft.

[0182] refer to Figures 27 to 29 In one embodiment, the piercing mechanism further includes a piercing sensor 322. When the piercing assembly 320 moves to the piercing position, the piercing sensor 322 is triggered to generate a sensing signal. When the piercing assembly 320 is at the piercing position, the coffee capsule is pierced. Thus, the sensing signal from the piercing sensor 322 can promptly notify the user that the piercing assembly 320 has pierced the coffee capsule.

[0183] refer to Figures 27 to 29 In one embodiment, the piercing mechanism further includes a retraction sensor 323. When the piercing assembly 320 moves to the retracted position, the retraction sensor 323 is triggered to generate a sensing signal. In the retracted position, the piercing assembly 320 is removed from the coffee capsule. Thus, the sensing signal from the retraction sensor 323 can promptly notify the user that the piercing assembly 320 has removed the coffee capsule.

[0184] The puncture sensing element 322 may be, but is not limited to, a micro switch, a reed switch, a tact switch, a Hall switch, etc. The retraction sensing element 323 may be, but is not limited to, a micro switch, a reed switch, a tact switch, a Hall switch, etc.

[0185] Specifically, the puncture mechanism may include a display device that displays the sensing results of the puncture sensor 322 and the retraction sensor 323, thereby conveniently notifying the user. The puncture mechanism may also include a puncture prompting device. When the puncture assembly 320 is in the puncture position, the puncture sensor 322 triggers the puncture prompting device to emit a puncture signal. When the puncture assembly 320 is in the retracted position, the retraction sensor 323 triggers the puncture prompting device to emit a retraction signal. Thus, the puncture prompting device can also be used to prompt the user. The puncture prompting device may be, for example, an audible prompting device, a visual prompting device, or a combined audible and visual prompting device.

[0186] refer to Figures 27 to 29 In one embodiment, the puncture sensor 322 is disposed on the fixed bracket 200 , and the retraction sensor 323 is disposed on the transmission bracket cover 470 .

[0187] refer to Figure 30 In one embodiment, the gear assembly is detachably connected to the rotary transmission member 461. The puncture mechanism includes a manual rotating member 480, which is connected to the rotary transmission member 461. Specifically, when the first drive device fails or loses power, the gear assembly and the rotary transmission member 461 can be disassembled, allowing the manual rotating member 480 to be connected to the rotary transmission member 461. The rotary transmission member 461 can then be manually rotated to drive the puncture assembly 320 to move.

[0188] refer to Figures 31 to 32 In one embodiment, the piercing assembly 320 includes a piercing sleeve 324 and a water channel frame 325 connected to the translation transmission member 462. The piercing sleeve 324 has a first piercing needle 321 at one end near the coffee capsule and an opening at the other end. The first piercing needle 321 is in communication with the inner cavity of the piercing sleeve 324.

[0189] The water channel 325 can enter the puncture sleeve 324 through the opening, and the outer circumference of the water channel 325 is sealed with the inner circumference of the puncture sleeve 324, thereby ensuring the seal between the water channel 325 and the puncture sleeve 324. One end of the water channel in the water channel 325 is connected to the inner cavity of the puncture sleeve 324, and the other end is the water inlet of the puncture assembly 320.

[0190] When the puncturing assembly 320 pierces the coffee capsule, specifically, the first puncturing needle 321 pierces the coffee capsule. After the first puncturing needle 321 pierces the coffee capsule, hot water can be introduced into the water inlet of the puncturing assembly 320. The hot water flows into the water channel of the water channel frame 325, enters the inner cavity of the puncturing sleeve 324, and then flows out of the first puncturing needle 321 and into the coffee capsule to extract the coffee liquid.

[0191] In one embodiment, the waterway frame 325 has a receiving cavity extending along the first direction, and the translation transmission member 462 is located in the receiving cavity and fixedly connected to the waterway frame 325. The translation transmission member 462 can be fixed relative to the receiving cavity by interference fit, welding, or the like.

[0192] refer to Figures 31 to 32 In one embodiment, the water channel frame 325 extends out of the opening of the puncture sleeve 324. The portion of the water channel frame 325 extending out of the opening is provided with a first extension portion 3251. The first extension portion 3251 protrudes from the puncture sleeve 324 in a direction perpendicular to the first direction. The water inlet of the puncture assembly 320 is provided at the end of the first extension portion 3251, thereby facilitating connection with a water pipe to allow for the introduction of hot water.

[0193] refer to Figures 31 to 32 In one embodiment, the waterway support 325 extends out of the opening of the puncture sleeve 324. The portion of the waterway support 325 extending out of the opening is provided with a first connecting portion 3252, which protrudes from the sidewall of the puncture sleeve 324 in a direction perpendicular to the first direction. The puncture sleeve 324 is provided with a second connecting portion 3241, which protrudes from the sidewall of the puncture sleeve 324 in a direction perpendicular to the first direction. The second connecting portion 3241 is located to one side of the first connecting portion 3252 along the first direction, and the two are fixedly connected, thereby facilitating the fixed connection between the waterway support 325 and the puncture sleeve 324.

[0194] refer to Figure 28 and Figure 29 , Figure 31 and Figure 32 In one embodiment, the puncture mechanism further includes a puncture sensing element 322. The first connecting portion 3252 is provided with a puncture sensing position. The puncture mechanism further includes the puncture sensing element 322. When the puncture assembly 320 moves to the puncture position, the puncture sensing position can trigger the puncture sensing element 322 to generate a sensing signal.

[0195] refer to Figure 28 and Figure 29 , Figure 31 and Figure 32 In one embodiment, the puncture mechanism further includes a retraction sensor 323. The first connecting portion 3252 is provided with a puncture sensing position. When the puncture assembly 320 moves to the retracted position, the puncture sensing position can trigger the retraction sensor 323 to generate a sensing signal.

[0196] By providing the first connecting portion 3252 , the water channel frame 325 and the puncture sleeve 324 can be fixedly connected through the fixed connection with the second connecting portion 3241 , and the puncture sensing component 322 and the retracting sensing component 323 can be triggered conveniently.

[0197] refer to Figure 31 and Figure 32In one embodiment, a sleeve sealing ring 3242 is provided between the puncture sleeve 324 and the water channel frame 325.

[0198] refer to Figure 28 and Figure 29 , Figure 31 and Figure 32 In one embodiment, the first puncture needle 321 is provided with a puncture sealing ring 3211. When the first puncture needle 321 punctures the coffee capsule, the puncture sealing ring 3211 abuts against the surface of the coffee capsule to ensure a sealed fit between the first puncture needle 321 and the coffee capsule.

[0199] An embodiment of the present application further provides a coffee machine, comprising a main unit 100 and the piercing mechanism of any one of the above embodiments, wherein a fixing bracket 200 is provided on the main unit 100 .

[0200] Please refer to Figure 34 One embodiment of the present application provides a beverage brewing assembly, comprising an extraction cup 330, a cup holder bracket 220, a leak-proof head 337 connected to the extraction cup 330, and a self-locking drive device disposed on the cup holder bracket 220. The cup holder bracket 220 is provided with a locking member 223, and the extraction cup 330 is provided with a mating structure 336. The locking member 223 has a locked position, in which it is locked with the mating structure 336, and an unlocked position, in which it is unlocked with the mating structure 336. The extraction cup 330 is provided with a liquid outlet (not shown), and the leak-proof head 337 has a closed position, in which it seals the liquid outlet, and an open position, in which it opens the liquid outlet. When the beverage brewing assembly is used in a coffee machine, the cup holder bracket 220 is disposed on the main unit 100 of the coffee machine.

[0201] The self-locking drive device includes a drive member 710 and a transmission structure 720. The transmission structure 720 includes a first transmission unit 721 and a second transmission unit. The drive member 710 drives the transmission structure 720 to move, causing the first transmission unit 721 to drive the locking member 223 from the unlocked position to the locked position, and the second transmission unit to drive the leak-proof head 337 from the closed position to the open position.

[0202] In the beverage brewing assembly described above, after the extraction cup 330 is placed on the cup holder bracket 220, the drive member 710 can drive the transmission structure 720 to move. The drive member 710 drives the transmission structure 720 to move, which can cause the first transmission unit 721 to drive the locking member 223 from the unlocked position to the locked position, thereby locking the extraction cup 330 on the cup holder bracket 220 to prevent the extraction cup 330 from being accidentally touched and falling during the coffee extraction process. The second transmission unit drives the leak-proof head 337 from the closed position to the open position, thereby opening the liquid outlet and allowing the coffee liquid to flow out for the user to enjoy. As can be seen, in the beverage brewing assembly of the embodiment of the present application, the locking of the extraction cup 330 and the cup holder bracket 220 and the opening and closing of the leak-proof head 337 can share a single drive member, thereby reducing the number of drive members and reducing the cost of the coffee machine.

[0203] In other embodiments, the beverage brewing component is not limited to being used in coffee machines, but can also be used in other beverage machines to brew other beverages (such as juice, tea).

[0204] In one embodiment, the movement of the transmission structure 720 driven by the driver 710 can be divided into a first phase and a second phase continuous with the first phase. During the first phase, the first transmission unit 721 can drive the locking member 223 from the unlocked position to the locked position. During the second phase, the first transmission unit 721 can maintain the locking member 223 in the locked position, and the second transmission unit can drive the stop-leak head 337 from the closed position to the open position.

[0205] After the extraction cup 330 is placed on the cup holder 220, the drive member 710 drives the transmission mechanism 720 to move. The transmission mechanism 720 first performs a first phase of movement, with the first transmission unit 721 driving the locking member 223 from an unlocked position to a locked position, thereby locking the extraction cup 330 to the cup holder 220. This prevents the extraction cup 330 from accidentally being knocked off during the coffee extraction process. Subsequently, coffee extraction can proceed. Before the transmission mechanism 720 performs a second phase of movement, the leak-proof head 337 is not driven to move and is in a closed position, sealing the liquid outlet. This prevents leakage from the liquid outlet during the coffee extraction process. When the coffee liquid is extracted, the drive member 710 continues to drive the transmission structure 720, and the transmission structure 720 enters the second stage of movement. In the second stage, the second transmission unit can drive the leak-proof head 337 to switch from the closed position to the open position, thereby opening the dispensing port and allowing the coffee liquid to flow out for the user to enjoy. In addition, during the second stage of the transmission structure 720, the first transmission unit 721 can maintain the locking member 223 in the locked position to stabilize the position of the extraction cup 330 during the coffee liquid dispensing process. As can be seen, in this embodiment, the drive member drives the transmission structure 720 in different stages of movement, so that the first transmission unit 721 drives the locking member 223 to switch from the unlocked position to the locked position, and the second transmission unit drives the leak-proof head 337 to switch from the closed position to the open position.

[0206] refer to Figure 34 In one embodiment, the extraction cup 330 includes a cup body 331 and a cup base 332 connected to the cup body 331. The liquid outlet is located on a side of the cup body 331 near the cup base 332. The extraction cup 330 also includes a filter 333, which is located at the liquid outlet and on the side of the leak-proof head 337 facing away from the cup base 332. The filter 333 is used to filter the coffee liquid.

[0207] refer to Figure 34 、 Figure 38 and Figure 39 In one embodiment, the beverage brewing assembly further includes a leak-proof elastic member 3372. The extraction cup 330 and the leak-proof head 337 are respectively connected to the leak-proof elastic member 3372. As previously described, when the driver 710 drives the transmission structure 720 in the second stage of movement, the leak-proof head 337 switches from the closed position to the open position; during this process, the leak-proof elastic member 3372 accumulates energy.

[0208] Once the coffee liquid has been dispensed, the outlet can be closed. At this point, the drive member 710 drives the transmission structure 720 to reverse direction. The transmission structure 720 first moves in the opposite direction of the second stage. During this process, the transmission structure 720 releases the leak-stopping head 337. The leak-stopping elastic member 3372, under its own elastic restoring force, drives the leak-stopping head 337 from the open position to the closed position, thereby closing the outlet. The provision of the leak-stopping elastic member 3372 facilitates the automatic switching of the leak-stopping head 337 to the closed position.

[0209] Specifically, the leak-proof elastic member 3372 can be a coil spring. The leak-proof elastic member 3372 can be mounted on the leak-proof head 337, with one end connected to the cup body 331 and the other end connected to the leak-proof head 337. When the leak-proof head 337 switches from the closed position to the open position, the leak-proof elastic member 3372 is compressed.

[0210] refer to Figure 34 、 Figure 35 and Figure 38 In one embodiment, the beverage brewing assembly further includes an unlocking elastic member 224, to which the locking member 223 and the cup holder bracket 220 are respectively connected. As previously described, when the driving member 710 drives the transmission structure 720 in the first stage of movement, the locking member 223 switches from the unlocked position to the locked position; during this process, the unlocking elastic member 224 accumulates energy.

[0211] Once the coffee liquid is discharged, the liquid outlet can be closed and the extraction cup 330 can be removed from the cup holder 220 for cleaning. At this point, the drive member 710 can drive the transmission structure 720 to reverse direction. The transmission structure 720 first moves in the opposite direction of the second stage, causing the leak-stopping elastic member 3372, under its own elastic restoring force, to switch the leak-stopping head 337 from the open position to the closed position, thereby closing the liquid outlet. The drive member 710 then continues to drive the transmission structure 720 in the opposite direction of the first stage. During this process, the transmission structure 720 releases the locking member 223, allowing the unlocking elastic member 224, under its own elastic restoring force, to switch the locking member 223 from the locked position to the unlocked position. The user can then remove the extraction cup 330 for cleaning. The provision of the unlocking elastic member 224 facilitates the automatic switching of the locking member 223 to the unlocked position.

[0212] refer to Figure 34 、 Figure 35 and Figure 38In one embodiment, the locking member 223 is a locking rod, and the mating structure 336 is a through-hole. When the locking member 223 is in the locked position, the locking rod is inserted into the through-hole. When the locking member 223 is in the unlocked position, the locking rod is removed from the through-hole. A guide groove can be provided on the cup holder bracket 220, and the locking member 223 cooperates with the guide groove to guide the movement of the locking member 223, allowing the locking member 223 to accurately switch between the locked and unlocked positions.

[0213] refer to Figure 34 、 Figure 35 and Figure 38 In one embodiment, a first protrusion 2231 is provided on the sidewall of the lock rod. The unlocking elastic member 224 is located between the first protrusion 2231 and the cup holder bracket 220. The two ends of the unlocking elastic member 224 abut against the cup holder bracket 220 and the first protrusion 2231, respectively. The elastic force of the unlocking elastic member 224 is used to drive the locking member 223 from the locked position to the unlocked position. The unlocking elastic member 224 can be a coil spring that is sleeved on the lock rod.

[0214] In one embodiment, the driving member 710 is a motor.

[0215] like Figures 35 to 37 As shown, in one embodiment, the first transmission unit 721 is a cam that rotates about the same axis in the first and second stages. The cam abuts the locking member 223, enabling the cam to drive the locking member 223 from the unlocked position to the locked position in the first stage and to maintain the locking member 223 in the locked position in the second stage. The cam can be connected to the output shaft of the driver 710. The cam can be rotatably connected to the cup holder bracket 220.

[0216] Specifically, the outer circumference of the cam includes a first portion and a second portion that are continuous along the circumference. The outer diameter of the first portion varies, while the outer diameter of the second portion is uniform. During the first stage of movement of the transmission structure 720, the first portion of the outer circumference of the cam abuts the locking member 223. Because the outer diameter of the first portion varies, when the cam rotates, the first portion can push the locking member 223 to move, causing the locking member 223 to switch from the unlocked position to the locked position. During the second stage of movement of the transmission structure 720, the second portion of the outer circumference of the cam abuts the locking member 223. Because the outer diameter of the second portion is uniform, during the rotation of the cam, the second portion abuts the locking member 223 while the locking member 223 remains in position. Thus, in this embodiment, by configuring the first transmission unit 721 as a cam, the first transmission unit 721 can drive the locking member 223 to switch to the locked position during the first stage while simultaneously maintaining the locking member 223 in the locked position during the second stage.

[0217] In one embodiment, the cam may be an involute cam.

[0218] In one embodiment, the movement direction of the locking rod is along the first direction Z, which is perpendicular to the rotation axis direction of the cam.

[0219] refer to Figure 39 In one embodiment, the second transmission unit includes a retaining segment 722 and an inclined segment 723. One end of the inclined segment 723 is connected to the retaining segment 722, and the retaining segment 722 and the inclined segment 723 rotate about the same axis. The second transmission unit rotates about this axis in the first and second stages. The retaining segment 722 extends perpendicular to the axis, that is, perpendicular to its rotation axis. The inclined segment 723 extends obliquely to the axis, that is, obliquely to the direction of its rotation axis.

[0220] refer to Figure 38 and Figure 39 The beverage brewing component also includes a leak-proof movable block 338 that is movably connected to the extraction cup 330. When the extraction cup 330 is placed on the cup holder bracket 220, the leak-proof movable block 338 is located on one side of the axis direction of the second transmission unit. When the transmission structure 720 moves in the first stage, the retaining segment 722 is used to abut against the end of the leak-proof movable block 338 away from the leak-proof head 337. Since the extension direction of the retaining segment 722 is perpendicular to its rotation axis, the retaining segment 722 abuts against the leak-proof movable block 338 during the first stage of rotation, but does not cause the position of the leak-proof movable block 338 to change. Therefore, when the transmission structure 720 drives the locking member 223 to move in the first stage, it will not affect the position of the leak-proof head 337. During the second stage of movement of the transmission structure 720, the inclined section 723 is used to abut against the end of the leak-stopping movable block 338 away from the leak-stopping head 337. Since the extension direction of the inclined section 723 is inclined relative to the direction of its rotation axis, the inclined section 723 can drive the leak-stopping movable block 338 to move during the second stage of rotation, and the leak-stopping movable block 338 pushes the leak-stopping head 337 from the closed position to the open position. Thus, in this embodiment, the retaining section 722 and the inclined section 723 of the second transmission unit ensure that the second transmission unit does not affect the position of the leak-stopping head 337 during the first stage, while the inclined section 723 can drive the leak-stopping head 337 to switch to the open position during the second stage.

[0221] In other embodiments, the first transmission unit is not limited to the above-mentioned cam structure, and the second transmission unit is not limited to the above-mentioned structure of the retaining segment and the tilting segment.

[0222] refer to Figure 38 to Figure 7 In one embodiment, the second transmission unit is located outside the first transmission unit 721.

[0223] refer to Figure 38 to Figure 7In one embodiment, the transmission structure 710 is rotatably connected to the cup holder bracket 220. The rotation axis of the cam is consistent with the rotation axis of the second transmission unit.

[0224] In one embodiment, the retaining section 722 may be a plane perpendicular to the direction of the rotation axis, and the inclined section 723 may be an inclined surface inclined to the direction of the rotation axis.

[0225] In other embodiments, the retaining section may be a sliding groove perpendicular to the direction of the rotation axis, and the inclined section may be a sliding groove inclined to the direction of the rotation axis.

[0226] refer to Figure 38 and Figure 39 In one embodiment, the movement direction of the leak-stopping head 337 when switching between the closed position and the open position is the first direction Z. The leak-stopping movable block 338 is movably connected to the extraction cup 330 along the third direction X. The driving member 710 is used to drive the transmission structure 720 to rotate about an axis in the third direction X. That is, the rotation axis of the transmission structure 720 is along the third direction X. The third direction X is perpendicular to the first direction Z.

[0227] The end of the leak-stopping movable block 338, which is adjacent to the leak-stopping head 337, is provided with a beveled abutment surface 3381. This beveled abutment surface 3381 is configured to abut against the leak-stopping head 337. This beveled abutment surface 3381 is inclined relative to both the third direction X and the first direction Z. Therefore, when the leak-stopping movable block 338 moves in the third direction X, the beveled abutment surface 3381 can push the leak-stopping head 337 along the first direction Z from the closed position to the open position.

[0228] Specifically, in this embodiment, the axial directions of the cam and the second transmission unit are both along the third direction X. Thus, when the second transmission unit rotates in the second stage, the inclined section 723 can drive the leak-stopping moving block 338 to move along the third direction X.

[0229] refer to Figure 38 and Figure 39 In one embodiment, the leak-stopping head 337 is provided with a mating rod (not shown) extending in the second direction Y. The inclined abutting surface 3381 is configured to abut the mating rod. The inclined abutting surface 3381 is parallel to the second direction Y. Thus, when the leak-stopping movable block 338 moves in the third direction X, the inclined abutting surface 3381 pushes the mating rod in the first direction Z, thereby moving the leak-stopping head 337 in the first direction Z from the closed position to the open position. The second direction Y is perpendicular to both the first direction Z and the third direction X.

[0230] refer to Figure 34 、 Figure 38 as well as Figure 39In one embodiment, the beverage brewing assembly further includes a leak-proof push rod 724 and a push rod elastic member 725. The leak-proof push rod 724 is movably connected to the cup holder bracket 220 along the third direction X. The leak-proof push rod 724 and the cup holder bracket 220 are each connected to the push rod elastic member 725. The elastic force of the push rod elastic member 725 is used to force one end of the leak-proof push rod 724 into contact with the retaining section 722 or the inclined section 723. When the extraction cup 330 is placed on the cup holder bracket 220, the leak-proof push rod 724 is positioned along the third direction X between the leak-proof movable block 338 and the second transmission unit.

[0231] During the first stage of movement of the transmission structure 720, the retaining segment 722 is used to abut against the end of the leak-stopping push rod 724 that is away from the leak-stopping movable block 338. Since the extending direction of the retaining segment 722 is perpendicular to its rotation axis, the retaining segment 722 abuts against the leak-stopping movable block 338 during the first stage of rotation, but does not cause the position of the leak-stopping movable block 338 to change. Therefore, during the first stage of movement of the locking member 223 driven by the transmission structure 720, the position of the leak-stopping head 337 is not affected.

[0232] During the second stage of movement of the transmission structure 720, the inclined section 723 is used to abut against the end of the leak-proof push rod 724 that is away from the leak-proof movable block 338. Because the extension direction of the inclined section 723 is inclined relative to the direction of its rotation axis, the inclined section 723 can push the leak-proof push rod 724 to move in the third direction X during the second stage of rotation. Therefore, the end of the leak-proof push rod 724 away from the inclined section 723 pushes the leak-proof movable block 338 to move in the third direction X, and the leak-proof movable block 338 pushes the leak-proof head 337 from the closed position to the open position. Moreover, during this process, the push rod elastic member 725 accumulates energy.

[0233] In this embodiment, the push rod elastic member 725 causes one end of the leak-proof push rod 724 to abut against the inclined section 723, and the other end to abut against the leak-proof moving block 338, thereby facilitating the movement of the leak-proof moving block 338 by the rotation of the inclined section 723. Furthermore, by providing the push rod elastic member 725, when the driving member 710 drives the transmission structure 720 to move in the opposite direction of the second stage, the push rod elastic member 725 drives the leak-proof push rod 724 to move under the action of its own elastic restoring force, so that the leak-proof push rod 724 always remains in abutment with the second transmission unit, thereby ensuring that the leak-proof push rod 724 always maintains good cooperation with the second transmission unit.

[0234] Combine Figure 35 、 Figure 36 、 Figure 38 、 Figure 39In one embodiment, the sidewall of the leak-proof push rod 724 is provided with a second protrusion 7241, and the push rod elastic member 725 is located between the second protrusion 7241 and the cup holder bracket 220. The ends of the push rod elastic member 725 respectively abut the cup holder bracket 220 and the second protrusion 7241 along the third direction X. In this way, the elastic force of the push rod elastic member 725 can act on the leak-proof push rod 724 through the second protrusion 7241. The provision of the second protrusion 7241 facilitates the mating of the push rod elastic member 725 and the leak-proof push rod 724.

[0235] Combine Figures 36 to 38 In one embodiment, the beverage brewing assembly further includes a drip sensor 726 disposed on the cup holder bracket 220. When the leak-stop head 337 switches from the closed position to the open position, the drip sensor 726 can generate a sensing signal, so that the user can promptly determine that the leak-stop head 337 has been opened based on the sensing signal generated by the drip sensor 726.

[0236] The drip sensor 726 can be, but is not limited to, a micro switch, a reed switch, a touch switch, a Hall switch, etc.

[0237] Furthermore, the beverage brewing assembly may include a dripping warning device. When the leak-stopping head 337 switches from the closed position to the open position, the sensing signal generated by the dripping sensor 726 can trigger the dripping warning device to emit a dripping warning signal, thereby also notifying the user that the leak-stopping head 337 has been opened through the dripping warning signal. The dripping warning device may be, for example, an audible warning device, a visual warning device, or an integrated audible and visual warning device.

[0238] Combine Figures 36 to 38 In one embodiment, a drip sensor is provided on the sidewall of the leak-stopping push rod 724. The beverage brewing assembly further includes a drip sensor 726 disposed on the cup holder bracket 220. When the leak-stopping push rod 724 moves to the leak-stopping movable block 338, driving the leak-stopping head 337 to switch to the open position, the drip sensor triggers the drip sensor 726 to generate a sensing signal. This allows the user to promptly determine that the leak-stopping head 337 is open based on the sensing signal generated by the drip sensor 726.

[0239] In one embodiment, the drip sensing position can be set on the second protrusion 7241. The second protrusion 7241 can facilitate the triggering of the drip sensing component 726 to generate a sensing signal, and can also facilitate the assembly of the top rod elastic component 725.

[0240] refer to Figure 35 and Figure 36In one embodiment, the beverage brewing assembly further includes a locking sensor 225 disposed on the cup holder bracket 220. The locking member 223 is provided with a locking sensing position. When the locking member 223 switches from the unlocked position to the locked position, the locking sensing position triggers the locking sensor 225 to generate a sensing signal. Thus, the user can confirm that the extraction cup 330 is locked based on the sensing signal generated by the locking sensor 225.

[0241] The locking sensor 225 can be, but is not limited to, a micro switch, a reed switch, a tact switch, a Hall switch, etc.

[0242] Furthermore, the beverage brewing assembly may include a lock prompting device. When the locking member 223 switches from the unlocked position to the locked position, the sensing signal generated by the lock sensing member 225 can trigger the lock prompting device to emit a lock prompting signal, thereby notifying the user through the lock prompting signal that the position of the extraction cup 330 is locked. The lock prompting device may be, for example, an audible prompting device, a light prompting device, or a combined audible and light prompting device.

[0243] refer to Figure 35 and Figure 36 In one embodiment, a first protrusion 2231 is provided on the side wall of the locking rod, and the beverage brewing assembly further includes a locking sensor 225 provided on the cup holder bracket 220. When the locking member 223 switches from the unlocked position to the locked position, the first protrusion 2231 can trigger the locking sensor 225 to generate an induction signal.

[0244] In this embodiment, the first protrusion 2231 is the lock sensing position. The first protrusion 2231 facilitates triggering the lock sensing member 225 to generate a sensing signal and facilitates the assembly of the unlocking elastic member 224.
