Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to beverage brewing components and coffee machines. Background Technology

[0002] Coffee machines can automatically control the entire coffee brewing process, including grinding, tamping, filling, brewing, and removing residue, making it convenient for people to enjoy coffee and thus increasingly entering people's lives.

[0003] The coffee machine includes components such as a cup holder and an extraction cup. The cup holder is equipped with a first motor, a locking mechanism, and a second motor. After the extraction cup is placed on the cup holder, the first motor drives the locking mechanism to secure the cup to the holder, preventing accidental drops. The extraction cup's spout has a leak-proof head. The second motor drives the leak-proof head to open or seal the spout. During coffee extraction, the leak-proof head seals the spout to ensure complete extraction and prevent leakage. When extraction is complete, the second motor drives the leak-proof head to open the spout, allowing coffee to flow into the coffee pot for enjoyment.

[0004] Therefore, it is evident that in existing coffee machines, each mechanism—locking the extraction cup and cup holder, and opening and closing the leak-proof head—requires a separate motor. This large number of motors results in a higher cost for the coffee machine. Utility Model Content

[0005] Therefore, it is necessary to address the issue that existing coffee machines require separate motors for locking the extraction cup and cup holder, and for opening and closing the leak-proof head. The large number of motors leads to high costs for the coffee machine. This paper proposes a beverage brewing component and a coffee machine.

[0006] One embodiment of this application provides a beverage brewing assembly, including: an extraction cup, a cup holder support, a leak-proof head connected to the extraction cup, and a self-locking drive device disposed on the cup holder support. The cup holder support is provided with a locking member, and the extraction cup is provided with a mating structure. The locking member has a locking position for locking with the mating structure and an unlocking position for unlocking from the mating structure. The extraction cup is provided with a liquid outlet, and the leak-proof head has a closed position for closing the liquid outlet and an open position for opening the liquid outlet.

[0007] The self-locking drive device includes a drive component and a transmission structure. The transmission structure includes a first transmission unit and a second transmission unit. The drive component drives the transmission structure to move, enabling the first transmission unit to switch the locking component from the unlocked position to the locked position, and the second transmission unit to switch the leak-proof head from the closed position to the open position.

[0008] In one embodiment, the motion of the drive member driving the transmission structure can be divided into a first stage and a second stage that is continuous with the first stage;

[0009] In the first stage, the first transmission unit can drive the locking member to switch from the unlocked position to the locked position; in the second stage, the first transmission unit can keep the locking member in the locked position, and the second transmission unit can drive the leak-stopping head to switch from the closed position to the open position.

[0010] In one embodiment, the first transmission unit is a cam that rotates about the same axis in the first and second phases; the cam abuts against the locking member so that in the first phase the cam can drive the locking member to switch from the unlocked position to the locked position, and in the second phase the locking member is held in the locked position.

[0011] In one embodiment, the second transmission unit includes a holding section and an inclined section, one end of the inclined section being connected to the holding section, the holding section and the inclined section being about the same axis, and the second transmission unit rotating about the axis in the first stage and the second stage; the extending direction of the holding section is perpendicular to the axis; the extending direction of the inclined section is inclined to the axis.

[0012] In one embodiment, the beverage brewing assembly further includes a leak-proof moving block movably connected to the extraction cup. In the first stage, the holding section of the second transmission unit is used to abut against the end of the leak-proof moving block away from the leak-proof head. In the second stage, the tilting section of the second transmission unit is used to abut against the end of the leak-proof moving block away from the leak-proof head, so that the tilting section can drive the leak-proof moving block to move, and the leak-proof moving block pushes the leak-proof head to switch from the closed position to the open position.

[0013] In one embodiment, the driving member is used to drive the transmission structure to rotate, and the rotation axis of the transmission structure is perpendicular to the movement direction of the leak-stopping moving block;

[0014] The leak-stopping moving block has a pushing slope at one end near the leak-stopping head; the pushing slope is inclined to the moving direction of the leak-stopping moving block and to the moving direction of the leak-stopping head, so that when the leak-stopping moving block moves, the pushing slope can push the leak-stopping head from the closed position to the open position.

[0015] In one embodiment, the beverage brewing assembly further includes a leak-proof top rod and a top rod elastic element. The leak-proof top rod is movably connected to the cup holder bracket, and the elastic force of the top rod elastic element is used to cause one end of the leak-proof top rod to abut against the retaining section or the inclined section.

[0016] In the second stage, the inclined section of the second transmission unit abuts against one end of the leak-stopping rod to push the leak-stopping rod to move, so that the end of the leak-stopping rod away from the inclined section pushes the leak-stopping moving block to move.

[0017] In one embodiment, the side wall of the leak-stopping rod is provided with a drip sensing position; the beverage brewing assembly also includes a drip sensor disposed on the cup holder bracket. When the leak-stopping rod moves to the leak-stopping moving block and drives the leak-stopping head to switch to the open position, the drip sensing position can trigger the drip sensor to generate a sensing signal.

[0018] In one embodiment, the beverage brewing assembly further includes a leak-proof elastic element. When the driving member drives the transmission structure to move in the opposite direction to the second stage, the leak-proof elastic element can drive the leak-proof head to switch from the open position to the closed position.

[0019] In one embodiment, the beverage brewing assembly further includes an unlocking elastic element. When the driving member drives the transmission structure to perform a movement opposite to the first stage, the unlocking elastic element can drive the locking member to switch from the locked position to the unlocked position.

[0020] In one embodiment, the beverage brewing assembly further includes a locking sensor disposed on the cup holder support; the locking sensor has a locking sensing position, and when the locking sensor switches from the unlocked position to the locked position, the locking sensing position can trigger the locking sensor to generate a sensing signal.

[0021] In one embodiment, the locking member is a locking rod, and the mating structure is a through hole; when the locking member is in the locked position, the locking rod is inserted into the through hole; when the locking member is in the unlocked position, the locking rod is removed from the through hole.

[0022] In one embodiment, the beverage brewing assembly further includes an unlocking elastic element, which is sleeved on the locking rod, and the elastic force of the unlocking elastic element is used to drive the locking rod to switch from the locked position to the unlocked position.

[0023] In one embodiment, the side wall of the locking rod is provided with a first protrusion, and the beverage brewing assembly further includes a locking sensor disposed on the cup holder bracket. When the locking sensor switches from the unlocked position to the locked position, the first protrusion can trigger the locking sensor to generate a sensing signal.

[0024] One embodiment of this application provides a coffee machine, including a main unit and a beverage brewing component as described in any of the above embodiments, wherein the cup holder is mounted on the main unit.

[0025] In a coffee machine equipped with the aforementioned beverage brewing components, after the extraction cup is placed on the cup holder, the transmission structure is moved by a drive unit. The transmission structure first undergoes a first-stage movement, where a first transmission unit moves a locking element from an unlocked position to a locked position, thus locking the extraction cup on the cup holder to prevent it from being accidentally knocked off during coffee extraction. Then, coffee extraction can begin. Before the transmission structure enters its second-stage movement, the leak-proof head is not driven and remains in the closed position, preventing leakage from the outlet during extraction. When coffee extraction is complete, the drive unit continues to drive the transmission structure, which then enters the second-stage movement. In this second stage, the second transmission unit moves the leak-proof head from the closed position to the open position, opening the outlet and allowing coffee to flow out for the user. Furthermore, during this second stage, the first transmission unit keeps the locking element in the locked position, ensuring the extraction cup remains stable during coffee dispensing. Therefore, it can be seen that in the coffee machine with the above-mentioned beverage brewing components in the embodiments of this application, the locking of the extraction cup and the cup holder bracket, and the opening and closing of the leak-proof head can share a single drive component, thereby saving the number of drive components and reducing the cost of the coffee machine.

[0045] Please refer to Figure 1 One embodiment of this application provides a beverage brewing assembly, which includes an extraction cup 330, a cup holder 220, a leak-proof head 337 connected to the extraction cup 330, and a self-locking drive device disposed on the cup holder 220. The cup holder 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 locking position for locking with the mating structure 336 and an unlocking position for unlocking from the mating structure 336. The extraction cup 330 has a liquid outlet (not shown), and the leak-proof head 337 has a closed position for closing the liquid outlet and an open position for opening the liquid outlet. When the beverage brewing assembly is applied to a coffee machine, the cup holder 220 is disposed on the main unit 100 of the coffee machine.

[0046] The self-locking drive device includes a drive component 710 and a transmission structure 720. The transmission structure 720 includes a first transmission unit 721 and a second transmission unit. By driving the transmission structure 720 through the drive component 710, the first transmission unit 721 can drive the locking component 223 to switch from the unlocked position to the locked position, and the second transmission unit can drive the leak-stopping head 337 to switch from the closed position to the open position.

[0047] In the aforementioned beverage brewing assembly, after the extraction cup 330 is placed on the cup holder 220, the drive component 710 drives the transmission structure 720 to move. The drive component 710 drives the transmission structure 720 to move, enabling the first transmission unit 721 to switch the locking component 223 from the unlocked position to the locked position, thereby locking the extraction cup 330 on the cup holder 220 to prevent it from being accidentally knocked off during coffee extraction. The second transmission unit drives the leak-proof head 337 from the closed position to the open position, thus opening the outlet and allowing coffee to flow out for the user to enjoy. Therefore, in this embodiment of the beverage brewing assembly, the locking of the extraction cup 330 and the cup holder 220, and the opening and closing of the leak-proof head 337, can share a single drive component, thereby saving on the number of drive components and reducing the cost of the coffee machine.

[0048] In other embodiments, the beverage brewing component is not limited to coffee machines, but can also be used in other beverage machines to brew other beverages (such as juice or tea).

[0049] In one embodiment, the movement of the drive member 710 driving the transmission structure 720 can be divided into a first stage and a second stage that continues the first stage. In the first stage, the first transmission unit 721 can drive the locking member 223 to switch from the unlocked position to the locked position. In the second stage, the first transmission unit 721 can keep the locking member 223 in the locked position, and the second transmission unit can drive the leak-stopping head 337 to switch from the closed position to the open position.

[0050] After the extraction cup 330 is placed on the cup holder 220, the drive unit 710 can drive the transmission structure 720 to move. The transmission structure 720 first performs a first-stage movement, where the first transmission unit 721 moves the locking member 223 from the unlocked position to the locked position, thus locking the extraction cup 330 on the cup holder 220 to prevent it from being accidentally knocked off during coffee extraction. Then, coffee extraction can begin. Before the transmission structure 720 performs a second-stage movement, the leak-proof head 337 is not driven and remains in the closed position, preventing leakage from the outlet during coffee extraction. When coffee extraction is complete, the drive unit 710 continues to drive the transmission structure 720, which then enters the second stage of movement. In the second stage, the second transmission unit can drive the leak-proof head 337 from the closed position to the open position, thereby opening the outlet and allowing the coffee to flow out for the user to enjoy. Furthermore, in the second stage, the first transmission unit 721 can keep the locking member 223 in the locked position, ensuring the stability of the extraction cup 330 during coffee dispensing. Therefore, in this embodiment, the drive unit drives the transmission structure 720 in different movement stages, 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.

[0051] like Figure 1 , Figure 2 As shown, in one embodiment, the beverage brewing assembly further includes a mounting bracket 210, and a cup holder bracket 220 is connected to the mounting bracket 210. The mounting bracket 210 is used to mount on the main unit 100, thereby allowing the cup holder bracket 220 to be mounted on the main unit 100.

[0052] like Figure 1 , Figure 2 As shown, in one embodiment, the mounting bracket 210 includes a mounting bracket body 211 and a mounting bracket cover 212 connected to each other.

[0053] like Figure 1 , Figure 2As shown, in one embodiment, the cup holder support 220 includes a cup holder support body 221 and a cup holder support shell 222 connected to each other.

[0054] refer to Figure 1 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 the side of the cup body 331 near the cup base 332. The extraction cup 330 also includes a filter screen 333, which is located at the liquid outlet and on the side of the leak-proof head 337 opposite to the cup base 332. The filter screen 333 is used to filter the coffee liquid.

[0055] refer to Figure 1 , Figure 5 and Figure 6 In one embodiment, the beverage brewing assembly further includes a leak-proof elastic element 3372. The extraction cup 330 and the leak-proof head 337 are respectively connected to the leak-proof elastic element 3372. As described above, when the drive member 710 drives the transmission structure 720 in the second stage of movement, the leak-proof head 337 switches from a closed position to an open position; during this process, the leak-proof elastic element 3372 stores energy.

[0056] Once the coffee liquid has been dispensed, the outlet can be closed. At this point, the drive component 710 can drive the transmission structure 720 to move in the opposite direction. The transmission structure 720 first moves in the opposite direction to the second stage. During this process, the transmission structure 720 releases the leak-stopping head 337, allowing the leak-stopping elastic element 3372 to drive the leak-stopping head 337 from the open position to the closed position under its own elastic restoring force, thus closing the outlet. By setting the leak-stopping elastic element 3372, it is convenient to automatically switch the leak-stopping head 337 to the closed position.

[0057] Specifically, the leak-proof elastic element 3372 can be a coil spring. The leak-proof elastic element 3372 can be sleeved 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. During the process of the leak-proof head 337 switching from the closed position to the open position, the leak-proof elastic element 3372 is compressed.

[0058] refer to Figure 1 , Figure 2 and Figure 5 In one embodiment, the beverage brewing assembly further includes an unlocking elastic member 224, and the locking member 223 and the cup holder support 220 are respectively connected to the unlocking elastic member 224. As described above, 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 stores energy.

[0059] Once the coffee has been dispensed, the spout can be closed, and the extraction cup 330 can be removed from the cup holder 220 for cleaning. At this point, the drive unit 710 can drive the transmission structure 720 in the opposite direction. The transmission structure 720 first moves in the opposite direction to the second stage, causing the leak-proof elastic element 3372 to drive the leak-proof head 337 from the open position to the closed position under its own elastic restoring force, thus closing the spout. Next, the drive unit 710 continues to drive the transmission structure 720 in the opposite direction to the first stage. During this process, the transmission structure 720 releases the locking element 223, allowing the unlocking elastic element 224 to drive the locking element 223 from the locked position to the unlocked position under its own elastic restoring force. This allows the user to remove the extraction cup 330 for cleaning. The unlocking elastic element 224 facilitates the automatic switching of the locking element 223 to the unlocked position.

[0060] refer to Figure 1 , Figure 2 and Figure 5 In 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 moves out of 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 direction of the locking member 223, so that the locking member 223 can accurately switch between the locked position and the unlocked position.

[0061] refer to Figure 1 , Figure 2 and Figure 5 In one embodiment, the side wall of the locking bar has a first protrusion 2231, and the unlocking elastic member 224 is located between the first protrusion 2231 and the cup holder bracket 220, so that both 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 to switch from the locked position to the unlocked position. The unlocking elastic member 224 can be a helical spring, sleeved on the locking bar.

[0062] In one embodiment, the drive element 710 is a motor.

[0063] like Figures 2 to 4 As shown, in one embodiment, the first transmission unit 721 is a cam, which rotates about the same axis in a first stage and a second stage. The cam abuts against the locking member 223 so that it can drive the locking member 223 from the unlocked position to the locked position in the first stage and hold the locking member 223 in the locked position in the second stage. The cam may be connected to the output shaft of the drive member 710. The cam and the cup holder bracket 220 may be rotatably connected.

[0064] Specifically, the outer peripheral surface of the cam includes a first part and a second part that are continuous in the circumferential direction. The outer diameter of the first part is variable, while the outer diameter of the second part is uniform and constant. During the first stage of movement, the first part of the outer peripheral surface of the cam abuts against the locking member 223. Since the outer diameter of the first part is variable, when the cam rotates, the first part 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, the second part of the outer peripheral surface of the cam abuts against the locking member 223. Since the outer diameter of the second part is uniform and constant, during the rotation of the cam, the second part abuts against the locking member 223, but the position of the locking member 223 remains unchanged. Therefore, in this embodiment, by setting 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 in the first stage, and simultaneously keep the locking member 223 in the locked position in the second stage.

[0065] In one embodiment, the cam may be an involute cam.

[0066] In one embodiment, the locking lever moves in a first direction Z, which is perpendicular to the rotation axis of the cam.

[0067] refer to Figure 7 In one embodiment, the second transmission unit includes a holding section 722 and an inclined section 723, one end of which is connected to the holding section 722. The holding section 722 and the inclined section 723 are about the same axis. The second transmission unit rotates about this axis in a first stage and a second stage. The extending direction of the holding section 722 is perpendicular to the axis, i.e., perpendicular to its rotation axis. The extending direction of the inclined section 723 is inclined to the axis, i.e., inclined to the direction of its rotation axis.

[0068] refer to Figure 5 and Figure 6The beverage brewing assembly also includes a leak-proof moving block 338 movably connected to the extraction cup 330. When the extraction cup 330 is placed on the cup holder 220, the leak-proof moving block 338 is located on one side of the axis of the second transmission unit. During the first stage of movement, the holding section 722 of the transmission structure 720 abuts against the end of the leak-proof moving block 338 away from the leak-proof head 337. Since the extending direction of the holding section 722 is perpendicular to its rotation axis, the holding section 722 abuts against the leak-proof moving block 338 during the first stage of rotation, but does not cause a change in the position of the leak-proof moving block 338. Therefore, during the first stage of driving the locking member 223, the transmission structure 720 does not affect the position of the leak-proof head 337. During the second stage of movement, the inclined section 723 of the transmission structure 720 abuts against the end of the leak-stopping moving block 338 away from the leak-stopping head 337. Since the extension direction of the inclined section 723 is inclined to its rotation axis, the inclined section 723 can drive the leak-stopping moving block 338 to move during the rotation of the second stage. The leak-stopping moving block 338 pushes the leak-stopping head 337 from the closed position to the open position. Thus, in this embodiment, through the holding section 722 and the inclined section 723 of the second transmission unit, the second transmission unit can be made to not affect the position of the leak-stopping head 337 in the first stage, and the inclined section 723 can drive the leak-stopping head 337 to switch to the open position in the second stage.

[0069] In other embodiments, the first transmission unit is not limited to the cam structure described above, and the second transmission unit is not limited to the structure of the holding section and the tilting section described above.

[0070] refer to Figures 5 to 7 In one embodiment, the second transmission unit is located on the periphery of the first transmission unit 721.

[0071] refer to Figures 5 to 7 In one embodiment, the transmission structure 710 is rotatably connected to the cup holder support 220. The rotation axis of the cam is aligned with the rotation axis of the second transmission unit.

[0072] In one embodiment, the holding segment 722 may be a plane perpendicular to its rotation axis, and the inclined segment 723 may be an inclined plane inclined to its rotation axis.

[0073] In other embodiments, the holding section may be a groove perpendicular to its rotation axis, and the inclined section may be a groove inclined to its rotation axis.

[0074] refer to Figure 5 and Figure 6In one embodiment, the leak-stopping head 337 moves in the first direction Z when switching between the closed and open positions. The leak-stopping moving 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 the axis of 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.

[0075] The leak-stopping moving block 338 has a pushing inclined surface 3381 at one end near the leak-stopping head 337. The pushing inclined surface 3381 is used to abut against the leak-stopping head 337. The pushing inclined surface 3381 is inclined in the third direction X and in the first direction Z. Therefore, when the leak-stopping moving block 338 moves along the third direction X, the pushing inclined surface 3381 can push the leak-stopping head 337 to move from the closed position to the open position along the first direction Z.

[0076] 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.

[0077] refer to Figure 5 and Figure 6 In one embodiment, the leak-stopping head 337 is provided with a mating rod (not shown) extending along a second direction Y. A pushing inclined surface 3381 is used to abut against the mating rod. The pushing inclined surface 3381 is parallel to the second direction Y. Thus, when the leak-stopping moving block 338 moves along a third direction X, the pushing inclined surface 3381 can push the mating rod to move along a first direction Z, causing the leak-stopping head 337 to move along the first direction Z from a closed position to an open position. The second direction Y is perpendicular to the first direction Z and perpendicular to the third direction X.

[0078] refer to Figure 1 , Figure 5 as well as Figure 6 In one embodiment, the beverage brewing assembly further includes a leak-proof top rod 724 and a top rod elastic member 725. The leak-proof top rod 724 is movably connected to the cup holder support 220 along a third direction X. The leak-proof top rod 724 and the cup holder support 220 are respectively connected to the top rod elastic member 725. The elastic force of the top rod elastic member 725 is used to cause one end of the leak-proof top rod 724 to abut against the holding section 722 or the inclined section 723. When the extraction cup 330 is placed on the cup holder support 220, the leak-proof top rod 724 is located between the leak-proof moving block 338 and the second transmission unit along a third direction X.

[0079] During the first stage of movement, the retaining section 722 of the transmission structure 720 abuts against the end of the leak-stopping rod 724 away from the leak-stopping moving block 338. Since the extending direction of the retaining section 722 is perpendicular to its rotation axis, the retaining section 722 abuts against the leak-stopping moving block 338 during the first stage of rotation, but does not cause a change in the position of the leak-stopping moving block 338. Therefore, during the first stage of driving the locking member 223, the transmission structure 720 does not affect the position of the leak-stopping head 337.

[0080] During the second stage of movement, the inclined section 723 of the transmission structure 720 abuts against the end of the leak-stopping rod 724 away from the leak-stopping moving block 338. Since the extension direction of the inclined section 723 is inclined to its rotation axis, during the second stage of rotation, the inclined section 723 can push the leak-stopping rod 724 to move along the third direction X, so that the end of the leak-stopping rod 724 away from the inclined section 723 pushes the leak-stopping moving block 338 to move along the third direction X. The leak-stopping moving block 338 pushes the leak-stopping head 337 to switch from the closed position to the open position. Moreover, during this process, the elastic element 725 of the rod stores energy.

[0081] In this embodiment, the elastic member 725 ensures that one end of the leak-stopping rod 724 abuts against the inclined section 723, and the other end abuts against the leak-stopping moving block 338, facilitating the movement of the leak-stopping moving block 338 by rotating the inclined section 723. Furthermore, by providing the elastic member 725, when the driving member 710 drives the transmission structure 720 to move in the opposite direction to the second stage, the elastic member 725, under its own elastic restoring force, drives the leak-stopping rod 724 to move, ensuring that the leak-stopping rod 724 always remains in contact with the second transmission unit, thereby ensuring that the leak-stopping rod 724 always maintains good cooperation with the second transmission unit.

[0082] Combination Figure 2 , Figure 3 , Figure 5 , Figure 6 In one embodiment, the side wall of the leak-stopping rod 724 is provided with a second protrusion 7241, and the elastic member 725 of the rod is located between the second protrusion 7241 and the cup holder bracket 220. Both ends of the elastic member 725 abut against the cup holder bracket 220 and the second protrusion 7241 respectively along a third direction X. Thus, the elastic force of the elastic member 725 can act on the leak-stopping rod 724 through the second protrusion 7241. The second protrusion 7241 facilitates the cooperation between the elastic member 725 and the leak-stopping rod 724.

[0083] Combination Figures 3 to 5In one embodiment, the beverage brewing assembly further includes a drip sensor 726 disposed on the cup holder 220. When the leak stop head 337 switches from the closed position to the open position, the drip sensor 726 generates 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.

[0084] The drip sensor 726 can be, but is not limited to, a micro switch, a reed switch, a tactile switch, a Hall switch, etc.

[0085] Furthermore, the beverage brewing assembly may include a drip indicator. When the leak stop head 337 switches from the closed position to the open position, the sensing signal generated by the drip sensor 726 can trigger the drip indicator to emit a drip indicator signal, thereby informing the user that the leak stop head 337 has been opened. The drip indicator may be, for example, an audible indicator, a visual indicator, or an integrated audible and visual indicator.

[0086] Combination Figures 3 to 5 In one embodiment, the side wall of the leak-stopping rod 724 is provided with a drip sensing position. The beverage brewing assembly also includes a drip sensor 726 disposed on the cup holder 220. When the leak-stopping rod 724 moves to the leak-stopping moving block 338, which drives the leak-stopping head 337 to switch to the open position, the drip sensing position can trigger the drip sensor 726 to generate a sensing signal, so that the user can promptly determine that the leak-stopping head 337 has been opened based on the sensing signal generated by the drip sensor 726.

[0087] In one embodiment, the drip sensing position can be provided on the second protrusion 7241. The second protrusion 7241 facilitates the triggering of the drip sensing element 726 to generate a sensing signal, and also facilitates the assembly of the top rod elastic element 725.

[0088] refer to Figure 2 and Figure 3 In one embodiment, the beverage brewing assembly further includes a locking sensor 225 disposed on the cup holder 220. The locking sensor 223 is provided with a locking sensing position. When the locking sensor 223 switches from the unlocked position to the locked position, the locking sensing position can trigger the locking sensor 225 to generate a sensing signal, so that the user can confirm that the position of the extraction cup 330 is locked based on the sensing signal generated by the locking sensor 225.

[0089] The locking sensor 225 may be, but is not limited to, a micro switch, a reed switch, a tactile switch, a Hall switch, etc.

[0090] Furthermore, the beverage brewing assembly may include a locking indicator. When the locking member 223 switches from the unlocked position to the locked position, the sensing signal generated by the locking sensor 225 can trigger the locking indicator to emit a locking indicator signal, thereby informing the user that the position of the extraction cup 330 is locked. The locking indicator may be, for example, an audible indicator, a visual indicator, or an integrated audible and visual indicator.

[0091] refer to Figure 2 and Figure 3 In one embodiment, the side wall of the locking rod is provided with a first protrusion 2231, and the beverage brewing assembly also includes a locking sensor 225 disposed on the cup holder 220. When the locking sensor 223 switches from the unlocked position to the locked position, the first protrusion 2231 can trigger the locking sensor 225 to generate a sensing signal.

[0092] In this embodiment, the first protrusion 2231 is the locking sensing position. The first protrusion 2231 facilitates the triggering of the locking sensing element 225 to generate a sensing signal, and also facilitates the assembly of the unlocking elastic element 224.
