Description

A beverage brewing apparatus and coffee machine

[0001] This application claims priority to Chinese Patent Application No. 202420841420.1, filed on April 22, 2024, with the China National Intellectual Property Administration, entitled “A Beverage Brewing Mechanism and Coffee Machine”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to, but is not limited to, the field of coffee machine technology, specifically to a beverage brewing apparatus and a coffee machine. Background Technology

[0003] Currently, coffee machines are becoming increasingly popular among consumers. In related technologies, a coffee machine includes a brewing mechanism. Coffee raw materials are placed in the brewing chamber of this mechanism, and a container for holding the coffee is positioned below the outlet of the brewing chamber. Hot water is added to the brewing chamber to extract the coffee from the raw materials, and during the extraction process, the coffee flows through the outlet into the container. However, the resulting coffee has a limited flavor and fails to satisfy the diverse taste preferences of different users. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a beverage brewing apparatus and a coffee machine that can enrich the flavor of coffee to meet the taste needs of different users.

[0005] This application provides a beverage brewing mechanism, including: a brewing body, the brewing body having a brewing chamber and a liquid outlet communicating with the brewing chamber; a leak-proof valve, movably installed at the liquid outlet and having a liquid outlet channel configured to communicate with the liquid outlet to discharge liquid from the brewing body; and a driving mechanism, connected to the leak-proof valve and configured to drive the leak-proof valve to move relative to the brewing body to control the opening and closing of the liquid outlet channel and the liquid outlet and to adjust the liquid flow rate of the liquid outlet channel.

[0006] The beverage brewing mechanism provided in this application includes a brewing body, a leak-proof valve, and a drive mechanism. The brewing body has a brewing chamber and a liquid outlet. The brewing chamber is used to hold the raw materials for preparing coffee, such as coffee beans and hot water. The extracted coffee is discharged from the brewing chamber through the liquid outlet and flows through the liquid outlet channel of the leak-proof valve into a container (such as a coffee pot) for the user to drink. The brewing chamber can be funnel-shaped, and the liquid outlet can be located at the bottom of the brewing chamber. The inner wall of the brewing chamber can be provided with guide ribs.

[0007] The check valve is used to control the opening and closing of the liquid outlet. When the outlet channel of the check valve is connected to the outlet of the brewing chamber, the outlet is open, allowing the coffee in the brewing chamber to drain out. When the outlet channel of the check valve is disconnected from the outlet of the brewing chamber, the outlet is closed, preventing the liquid in the brewing chamber from draining out. This prevents liquid (such as leftover coffee or residual water from cleaning the brewing chamber) from continuing to drip from the brewing chamber after the coffee container is removed, thus avoiding wetting the table or countertop.

[0008] The drive mechanism is used to move the check valve, thereby adjusting the relative position of the check valve and the brewing body, realizing the opening and closing control of the liquid outlet by the check valve, and regulating the liquid flow rate. The drive mechanism can be an electrically driven mechanism, which facilitates automatic control of the check valve, eliminating the need for manual adjustment by the user and improving the user experience.

[0009] In related technologies, no check valve is installed at the outlet, or the check valve only has two states: open and closed. Therefore, the flow rate is constant, resulting in a limited coffee flavor. In this embodiment, however, the check valve can be opened or closed; closing it allows for a blooming effect. Furthermore, the flow rate of the outlet channel is adjustable and is related to the concentration of the extracted coffee. When the flow rate is low, the liquid used for extraction stays in the brewing chamber for a longer time, resulting in a higher coffee concentration and a richer flavor. When the flow rate is high, the liquid stays in the brewing chamber for a shorter time, resulting in a lower coffee concentration and a weaker flavor. Therefore, by adjusting the flow rate of the outlet channel, the coffee concentration can be adjusted, allowing for controllable blooming and enriching the flavor profile to meet the diverse taste preferences of different users.

Detailed Implementation

[0044] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0045] As shown in Figures 1 to 6, this application provides a beverage brewing mechanism 100, including: a brewing body 1, a leak-proof valve 2, and a drive mechanism 3.

[0046] The brewing body 1 is provided with a brewing chamber 11 and a liquid outlet 111 connected to the brewing chamber 11, as shown in Figures 5 and 6.

[0047] The leak-proof valve 2 is movably installed at the liquid outlet 111 and is provided with a liquid outlet channel 2112. The liquid outlet channel 2112 is configured to communicate with the liquid outlet 111 to discharge the liquid inside the brewing body 1.

[0048] The drive mechanism 3 is connected to the leak-proof valve 2 and is configured to drive the leak-proof valve 2 to move relative to the brewing body 1 to control the opening and closing between the liquid outlet channel 2112 and the liquid outlet 111 and to adjust the liquid flow rate of the liquid outlet channel 2112.

[0049] The beverage brewing mechanism 100 provided in this embodiment includes a brewing body 1, a leak-proof valve 2, and a drive mechanism 3. The brewing body 1 is provided with a brewing chamber 11 and a liquid outlet 111. The brewing chamber 11 is used to hold the raw materials for preparing coffee, such as coffee beans and hot water. The extracted coffee is discharged from the brewing chamber 11 through the liquid outlet 111 and enters a container (such as a coffee pot 200) for drinking through the liquid outlet channel 2112 of the leak-proof valve 2. The brewing chamber 11 may be funnel-shaped, and the liquid outlet 111 may be located at the bottom of the brewing chamber 11. The inner wall surface of the brewing chamber 11 may be provided with guide ribs 112.

[0050] The leak-proof valve 2 is used to control the opening and closing of the liquid outlet 111. When the liquid outlet channel 2112 of the leak-proof valve 2 is connected to the liquid outlet 111 of the brewing chamber 11, the liquid outlet 111 is opened, as shown in Figures 4 and 6, allowing the coffee in the brewing chamber 11 to drain out. When the liquid outlet channel 2112 of the leak-proof valve 2 is disconnected from the liquid outlet 111 of the brewing chamber 11, the liquid outlet 111 is closed, as shown in Figures 3 and 5, preventing the liquid in the brewing chamber 11 from draining out. This is to avoid the brewing chamber 11 continuing to drip liquid (such as remaining coffee or residual water from cleaning the brewing chamber 11) after the coffee container is removed, which could wet the table or countertop.

[0051] The drive mechanism 3 is used to drive the movement of the stop valve 2 to adjust the relative position of the stop valve 2 and the brewing body 1, thereby controlling the opening and closing of the outlet 111 by the stop valve 2 and regulating the flow rate of the liquid. The drive mechanism 3 can be an electrically driven mechanism, which facilitates automatic control of the stop valve 2 without requiring manual adjustment by the user, thus improving the user experience.

[0052] In related technologies, no stop valve is installed at the outlet, or the stop valve only has two states: open and closed. Therefore, the flow rate is constant, resulting in a limited coffee flavor. In this embodiment, however, the stop valve 2 can be opened or closed; closing it allows for a blooming effect. Furthermore, the flow rate of the outlet channel 2112 is adjustable and is related to the concentration of the extracted coffee. When the flow rate is low, the liquid used for extraction stays in the brewing chamber 11 for a longer time, resulting in a higher coffee concentration and a richer flavor. When the flow rate is high, the liquid used for extraction stays in the brewing chamber 11 for a shorter time, resulting in a lower coffee concentration and a weaker flavor. Therefore, by adjusting the flow rate of the outlet channel 2112, the coffee concentration can be adjusted, allowing for controllable blooming and enriching the coffee's flavor to meet the taste preferences of different users.

[0053] In some exemplary embodiments, the leak-proof valve 2 includes a valve core 21. The valve core 21 is provided with a liquid outlet channel 2112 and a liquid inlet 2111 communicating with the liquid outlet channel 2112, as shown in Figures 5, 6, and 7. The liquid inlet 2111 allows liquids such as coffee in the brewing chamber 11 to enter the liquid outlet channel 2112.

[0054] The valve core 21 is movably installed at the liquid outlet 111 to control the opening and closing of the liquid inlet 2111 and adjust the opening area of ​​the liquid inlet 2111, thereby controlling the connection and disconnection between the liquid outlet channel 2112 and the liquid outlet 111 and adjusting the liquid flow rate of the liquid outlet channel 2112.

[0055] The drive mechanism 3 is connected to the valve core 21 and is configured to drive the valve core 21 to move relative to the brewing body 1.

[0056] When the inlet 2111 of the leak-proof valve 2 is connected to the outlet 111 of the brewing chamber 11, liquids such as coffee in the brewing chamber 11 can enter the outlet channel 2112, thus connecting the outlet 111 of the brewing chamber 11 with the outlet channel 2112. When the inlet 2111 of the leak-proof valve 2 is disconnected from the outlet 111 of the brewing chamber 11, liquids such as coffee in the brewing chamber 11 cannot enter the outlet channel 2112, thus isolating the outlet 111 of the brewing chamber 11 with the outlet channel 2112.

[0057] By controlling the movement of the leak-proof valve 2 relative to the brewing body 1, the opening area of ​​the liquid inlet 2111 can be adjusted, thereby adjusting the liquid flow rate into the liquid outlet channel 2112, thus achieving the regulation of the liquid outlet flow rate.

[0058] Of course, the movement of the leak-proof valve 2 is not limited to the moving mode. For example, it can also include the rotating mode. By rotating the leak-proof valve 2, the opening area of ​​the liquid inlet 2111 can be adjusted, thereby adjusting the liquid flow rate entering the liquid outlet channel 2112, thus achieving the adjustment of the liquid outlet flow rate. It can also include both rotation and movement. By rotating and moving the leak-proof valve 2, the opening area of ​​the liquid inlet 2111 can be adjusted, thereby adjusting the liquid flow rate entering the liquid outlet channel 2112, thus achieving the adjustment of the liquid outlet flow rate.

[0059] In some exemplary embodiments, the drive mechanism 3 includes a drive member 31 and a transmission assembly. The drive member 31 is connected to the transmission assembly and configured to drive the transmission assembly to move. The transmission assembly is connected to the valve core 21 and configured to drive the valve core 21 to move relative to the brewing body 1.

[0060] The transmission assembly includes a transmission member 32 and a linkage member 33. The transmission member 32 is connected to the drive member 31 and is configured to move along a first direction under the drive of the drive member 31. The linkage member 33 cooperates with the transmission member 32 and the valve core 21 and is configured to move along a second direction under the drive of the transmission member 32, so as to drive the valve core 21 to move relative to the brewing body 1 in the second direction. The second direction is different from the first direction.

[0061] This facilitates the selection of the type of drive component 31 and the reasonable arrangement of its position as needed, which is beneficial for optimizing the structure and layout of the beverage brewing mechanism 100.

[0062] In some exemplary embodiments, the transmission member 32 includes a drive slider 321, as shown in Figures 5, 6, and 9 to 11. The drive slider 321 is configured to slide along a first direction under the drive of the drive member 31. The drive slider 321 has a drive ramp 3212, as shown in Figures 5, 10, and 13. The linkage member 33 has a mating ramp 3311, as shown in Figures 5 and 11. The drive ramp 3212 is configured to engage with the mating ramp 3311 to drive the linkage member 33 to move along a second direction.

[0063] In other words, the transmission member 32 and the linkage member 33, through the engagement of the wedge-shaped inclined surface, realize the conversion of the movement of the transmission member 32 along the first direction into the movement of the linkage member 33 along the second direction. The second direction can be perpendicular to the first direction.

[0064] Of course, the cooperation between the transmission component 32 and the linkage component 33 is not limited to this. For example, the transmission component 32 can be a gear, and the linkage component 33 can be a rack. The gear rotates in the first direction, driving the rack to move in the second direction, and the rack drives the valve core 21 to move in the second direction.

[0065] In some exemplary embodiments, the linkage 33 includes a mating slider 331 and a liquid outlet 332 disposed on the mating slider 331, as shown in Figures 5, 14, and 15. The mating slider 331 is provided with a mating inclined surface 3311. The second direction is the axial direction of the liquid outlet 111. The liquid outlet 332 communicates with the liquid outlet channel 2112 and abuts against the bottom of the valve core 21, as shown in Figures 5 and 6. The axial direction of the liquid outlet 111 is usually vertical, so the second direction is vertical. The first direction can be horizontal.

[0066] In this way, the coffee (or other liquid) in the brewing chamber 11 can be discharged through the outlet channel 2112 of the leak-proof valve 2 and then discharged downwards through the outlet nozzle 332. This facilitates the smooth discharge of coffee into the container used to hold the coffee and helps to avoid the transmission components affecting the smooth discharge of coffee.

[0067] In some exemplary embodiments, the valve core 21 includes a valve stem 211, as shown in Figures 5 and 7. The valve stem 211 is inserted into the outlet 111 along a second direction. The inlet 2111 is located on the side wall of the valve stem 211, and the outlet channel 2112 is located inside the valve stem 211.

[0068] As shown in Figures 5 and 7, the valve core 21 also includes an abutment portion 212 sleeved on the outside of the valve stem 211 and connected to the valve stem 211. The abutment portion 212 and the valve stem 211 enclose a receiving groove 2121, and the bottom of the receiving groove 2121 is provided with a drain port 2122. The top of the liquid outlet 332 abuts against the abutment portion 212, and the liquid outlet 332 is also connected to the drain port 2122.

[0069] As shown in Figures 3 and 5, when the stop valve 2 is in the position of disconnecting the liquid outlet channel 2112 from the liquid outlet 111, the liquid inlet 2111 is located outside the brewing chamber 11 and is in a closed state. When the stop valve 2 moves upward, the liquid inlet 2111 moves upward. When the liquid inlet 2111 begins to enter the brewing chamber 11, it can connect with the liquid outlet 111 and is in an open state, as shown in Figures 4 and 6. The different degrees of upward movement of the valve core 21 result in different areas of the liquid inlet 2111 entering the brewing chamber 11, thus resulting in different opening areas of the liquid inlet 2111.

[0070] The number of liquid inlets 2111 can be multiple. Multiple liquid inlets 2111 can be arranged at intervals along the circumference of the valve core 21, multiple liquid inlets 2111 can also be arranged at intervals along the axial direction of the valve core 21, or multiple liquid inlets 2111 can be arranged at intervals along both the circumference and axial direction of the valve core 21.

[0071] The design of the receiving tank 2121 facilitates the flow of coffee from the gap between the valve stem 211 and the outlet 111 into the receiving tank 2121, and then discharges it into the outlet 332 through the drain port 2122 of the receiving tank 2121, preventing liquid leaking from the gap between the valve core 21 and the outlet 111 from spilling everywhere. Multiple drain ports 2122 can be provided, spaced apart circumferentially along the receiving tank 2121.

[0072] In some exemplary embodiments, as shown in FIG5, the check valve 2 further includes a second sealing member 22, fitted onto the valve core 21, configured to seal the outlet 111 when the check valve 2 is in the position of disconnecting the outlet 111 from the outlet channel 2112. The outer diameter of the second sealing member 22 may be larger than the diameter of the outlet 111, and at least a portion of the outer diameter of the valve stem 211 may be smaller than the diameter of the outlet 111. Thus, the valve stem 211 can move up and down along the outlet 111, and when the second sealing member 22 abuts against the outlet 111, it can close and seal the outlet 111, as shown in FIG5. If the second sealing member 22 is located inside the brewing chamber 11, it will close the outlet 111 when it moves downward to its final position.

[0073] As shown in Figures 5 and 6, the beverage brewing mechanism 100 further includes a second elastic element 23, which cooperates with the valve core 21 and is configured to use its restoring elastic force to drive the leak-proof valve 2 to move in the direction of disconnecting the liquid outlet 111 from the liquid outlet channel 2112. This helps the leak-proof valve 2 to remain stably in the position of closing the liquid outlet 111. Of course, the leak-proof valve 2 may also not include the second elastic element 23, and can be held in the position of closing the liquid outlet 111 by the weight of the leak-proof valve 2.

[0074] The abutment portion 212 of the valve core 21 can also be used to cooperate with the second elastic element 23. The second elastic element 23 can be a spring, which is sleeved on the outside of the valve stem 211, with one end abutting against the abutment portion 212 and the other end abutting against the brewing body 1 and located outside the brewing chamber 11. During the upward movement of the valve core 21, the second elastic element 23 is compressed, storing elastic potential energy. During the downward movement of the valve core 21, the second elastic element 23 releases elastic potential energy, providing a downward force to the valve core 21, which helps the valve core 21 to be stably maintained in the closed outlet 111 position. The abutment portion 212 and the valve stem 211 can be an integral structure or a separate assembly structure.

[0075] The second sealing element 22 can be a sealing ring. The valve stem 211 can be provided with a sealing groove 2113, as shown in Figures 5 and 7, and the second sealing element 22 is fitted into the sealing groove 2113. When the check valve 2 moves downward to the position of closing the outlet 111, the second sealing element 22 abuts against the inner bottom wall of the brewing chamber 11 to seal the outlet 111, as shown in Figure 5. During installation, the top of the valve stem 211 can be passed through the outlet 111 from bottom to top first, and then the second sealing element 22 can be fitted onto the valve stem 211 from top to bottom. After loosening, the check valve 2 can be stably positioned in the position of closing the outlet 111 under the force of gravity and the action of the second elastic element 23.

[0076] In some embodiments, as shown in Figures 3 and 4, the brewing body 1 includes a brewing cup and a base. The brewing cup includes a brewing chamber 11 and a cup shell 12 fitted over the outside of the brewing chamber 11. The brewing chamber 11 and the cup shell 12 can be an integral structure or a separate assembly structure. The bottom of the brewing chamber 11 is provided with a liquid outlet 111. The base is fitted inside the bottom of the cup shell 12 and is fixedly connected to the brewing cup. The base is provided with a clearance space corresponding to and communicating with the liquid outlet 111, as shown in Figures 5 and 6. The portion of the leak-proof valve 2 located outside the brewing chamber 11 can be hidden within the clearance space. The outer bottom wall of the brewing chamber 11 is provided with a nested first hollow column 114 and a second hollow column 115, as shown in Figure 5. The internal space of the first hollow column 114 is correspondingly connected to the liquid outlet 111. The first hollow column 114 and the second hollow column 115 are also located within the clearance space. The valve stem 211 passes through the first hollow column 114. The second hollow column 115 is inserted into the receiving groove 2121 of the valve core 21. The upper end of the second elastic member 23 is limited to the gap between the first hollow column 114 and the second hollow column 115. The inner bottom wall of the brewing chamber 11 is provided with a stepped groove 113, as shown in Figure 5. When the leak-proof valve 2 moves downward to the position of closing the liquid outlet 111, the second sealing member 22 is located in the stepped groove 113. The valve stem 211 can be a stepped shaft, including a large shaft section and a small shaft section. The liquid inlet 2111 is located in the small shaft section, which facilitates the smooth entry of coffee into the liquid outlet channel 2112 and the receiving groove 2121.

[0077] In some exemplary embodiments, as shown in FIG2, the beverage brewing mechanism 100 further includes: a mounting base 4, on which the drive mechanism 3 is mounted. The mounting base 4 is provided with a groove 44 extending in a first direction and a guide hole 411 extending in a second direction. The drive slider 321 is limited to the groove 44 and configured to slide along the groove 44. The dispensing nozzle 332 passes through the guide hole 411 and is configured to move along the guide hole 411.

[0078] Mounting base 4 can serve as the mounting carrier for drive mechanism 3, providing support and protection for drive mechanism 3. It can also guide and limit drive slider 321 and liquid outlet 332, which helps improve the reliability of drive mechanism 3.

[0079] In some exemplary embodiments, as shown in Figures 5 and 6, the mounting base 4 includes a bottom shell 42 and a cover shell 41. The cover shell 41 is fitted and connected to the bottom shell 42, and together with the bottom shell 42, encloses a mounting cavity 43, as shown in Figure 6. A sliding groove 44 is provided within the mounting cavity 43. A guide hole 411 is provided within the cover shell 41. At least a portion of the drive mechanism 3 is located within the mounting cavity 43.

[0080] In this way, the mounting base 4 can provide better protection for the drive mechanism 3, and also helps to improve the simplicity of the appearance of the beverage brewing mechanism 100, thereby improving the aesthetics of the product.

[0081] The bottom shell 42 and the cover shell 41 can be machined separately, which helps reduce the processing difficulty. The bottom shell 42 and the cover shell 41 can be fixed together by means of screwing, riveting, snap-fitting, or plugging. The cover shell 41 can be provided with two first guide ribs, forming a groove 44 between the two first guide ribs. The bottom shell 42 can be provided with two second guide ribs 423, as shown in Figure 9, forming a groove 44 between the two first guide ribs. The first guide ribs and the second guide ribs 423 can be correspondingly set to abut each other, or they can be fitted with a stop. In this way, both the bottom shell 42 and the cover shell 41 can play a limiting and guiding role for the drive slider 321. Stops 441 can be provided at both ends of the groove 44, as shown in Figure 9, to limit the starting and ending positions of the drive slider 321.

[0082] As shown in Figures 5 and 8, the cover 41 can be provided with a limiting groove 414, the first sealing element 35 can be a sealing ring, the first sealing element 35 is partially limited in the limiting groove 414, and is sleeved between the part of the liquid outlet 332 inserted into the guide hole 411 and the hole wall of the guide hole 411.

[0083] In some exemplary embodiments, both the drive slider 321 and the mating slider 331 are located within the mounting cavity 43.

[0084] The outlet nozzle 332 penetrates the sliding block 331 along the second direction. As shown in Figures 5, 14, and 15, the outlet nozzle 332 includes an inlet section 3321 located on the side of the sliding block 331 closer to the leak-proof valve 2 (i.e., the upper side) and an outlet section 3322 located on the side of the sliding block 331 away from the leak-proof valve 2 (i.e., the lower side). The bottom of the outlet section 3322 may have multiple outlets spaced circumferentially. The inlet section 3321 passes through the guide hole 411.

[0085] The dispensing nozzle 332 and the matching slider 331 can be an integral structure or a separate assembly structure. As shown in Figure 5, the dispensing nozzle 332 can be configured as a stepped structure, with the flow area of ​​the inlet section 3321 being larger than that of the outlet section 3322. In other words, the inlet section 3321 is wider to ensure that the coffee in the dispensing channel 2112 and the receiving tank 2121 can smoothly enter the dispensing nozzle 332; the outlet section 3322 is narrower to facilitate the smooth flow of coffee into the container used to hold the coffee and prevent spillage. As shown in Figures 5 and 15, the dispensing nozzle 332 can also include a transition section 3323 located between the inlet section 3321 and the outlet section 3322. The transition section 3323 can be configured as a funnel shape to facilitate the collection of coffee into the outlet section 3322.

[0086] The drive slider 321 is provided with a first clearance hole 3211 for avoiding the liquid outlet section 3322, as shown in Figures 9, 10, 11 and 13. The first clearance hole 3211 can pass through the end of the drive slider 321 away from the drive member 31 along a first direction.

[0087] The bottom shell 42 is provided with a second clearance hole 422 corresponding to the liquid outlet section 3322, as shown in Figure 5. Since the liquid outlet channel 2112 is separated from the liquid outlet 111, the liquid outlet section 3322 passes through the second clearance hole 422. The second clearance hole 422 can be a circular hole.

[0088] In some exemplary embodiments, the bottom of the sliding block 331 is provided with an annular clearance groove 3312, as shown in Figures 5, 11, and 14. The clearance groove 3312 is fitted onto the outside of the liquid outlet section 3322. The bottom shell 42 is provided with an annular limiting boss 421, as shown in Figure 5. The limiting boss 421 surrounds the second clearance hole 422. Since the liquid outlet channel 2112 is separated from the liquid outlet 111, the limiting boss 421 is embedded in the clearance groove 3312, as shown in Figure 5. This helps to improve the positional stability of the liquid outlet nozzle 332 and the sliding block 331 when the liquid outlet 111 is closed.

[0089] In some exemplary embodiments, the drive mechanism 3 further includes a first elastic member 34 and a first seal member 35, as shown in Figures 5 and 6.

[0090] The first elastic element 34 cooperates with the linkage element 33, and is configured to use its restoring elastic force to drive the linkage element 33 to move in the second direction away from the valve core 21. A limiting groove 3314 can be provided on the top surface of the sliding block 331, as shown in Figures 5 and 15. The first elastic element 34 can be a spring, sleeved on the outside of the inlet section 3321 of the outlet nozzle 332. The lower end of the first elastic element 34 is embedded in the limiting groove 3314 of the sliding block 331, and the upper end of the first elastic element 34 abuts against the cover 41, and can be sleeved on the outside of the limiting step 415 of the cover 41. The limiting groove 3314 can be located radially outside the second mounting groove 3313.

[0091] As shown in Figure 6, the first sealing element 35 is sleeved between the liquid outlet 332 and the guide hole 411, and is configured to seal the gap between the liquid outlet 332 and the guide hole 411.

[0092] During the upward movement of the linkage 33, the first elastic element 34 is compressed, storing elastic potential energy. During the downward movement of the linkage 33, the first elastic element 34 releases elastic potential energy, providing a downward force to the linkage 33, which helps the linkage 33 to remain stably in the position abutting against the bottom shell 42.

[0093] Of course, the drive mechanism 3 may also exclude the first elastic element 34 and use the gravity of the linkage 33 to maintain it in a position against the bottom shell 42.

[0094] In some examples, as shown in Figure 5, the first seal 35 includes an annular sealing body 351 and a first lip 352 and a second lip 353 respectively located at the axial ends of the sealing body 351. Both the first lip 352 and the second lip 353 extend radially outward along the sealing body 351. The outer top wall of the cover 41 is recessed with a first mounting groove, as shown in Figures 5 and 8, where the first lip 352 is confined. The inner top wall of the cover 41 may have a downwardly protruding limiting step 415, as shown in Figure 5, where the second lip 353 abuts against the lower end face of the limiting step 415. The upper surface of the sliding block 331 may have a recessed second mounting groove 3313, as shown in Figures 5 and 15, which is used to mate with the second lip 353. When the valve core 21 moves upward to its final position, the second lip 353 is embedded in the second mounting groove 3313, as shown in Figure 6, positioning the final position of the dispensing nozzle 332.

[0095] In some exemplary embodiments, as shown in Figures 5, 6, and 12, the drive component 31 includes a drive motor 311 and a lead screw 312 connected to the drive motor 311. The drive slider 321 has a threaded hole, and the lead screw 312 is threadedly connected to the threaded hole.

[0096] The drive motor 311 drives the lead screw 312 to rotate, and the lead screw 312 drives the drive slider 321 to slide in the first direction. The lead screw 312 can be a single-start lead screw 312, a double-start lead screw 312, or a lead screw 312 with more than one start. By adjusting the rotation amplitude of the drive motor 311, the rotation amplitude of the lead screw 312 can be adjusted, thereby increasing the sliding amplitude of the entire drive slider 321, and thus adjusting the lifting amplitude of the linkage 33 and the leak-proof valve 2.

[0097] The drive unit 31 may also include a gear transmission mechanism located between the drive motor 311 and the lead screw 312, which facilitates the adjustment of the transmission ratio.

[0098] As shown in Figures 8 and 9, the drive mechanism 3 may further include a connector 36 electrically connected to the drive motor 311. The mounting base 4 may have a mounting notch 413, as shown in Figure 8, through which the connector 36 extends to the outside of the mounting base 4, facilitating electrical connection with the main control board inside the coffee machine base 300. The base 300 may be correspondingly equipped with the connector 36, and the electrical connection between the drive mechanism 3 and the main control board is achieved through the mating of the connector 36, enabling the main control board to control the drive mechanism 3.

[0099] In some exemplary embodiments, the drive slider 321 has a countersunk hole 3213, as shown in FIG13. A nut 322 is housed within the countersunk hole 3213, as shown in FIGS. 5 and 6. The nut 322 has a threaded hole. The drive slider 321 also has a third clearance hole 3214 communicating with the threaded hole, as shown in FIG5. The third clearance hole 3214 is configured to allow the lead screw 312 to pass through the portion of the nut 322. This simplifies the structure of the drive slider 321 and facilitates its machining.

[0100] The nut 322 can be fixedly connected to the drive slider 321 by means of screwing, riveting, snap-fitting, etc. For example, the mounting nut 322 has two holes, and is fixedly connected to the drive slider 321 by two screws 323 (as shown in Figure 10). The nut 322 can also be integrally formed with the drive slider 321 through processes such as plastic coating.

[0101] In some exemplary embodiments, as shown in Figures 9 and 10, the beverage brewing mechanism 100 further includes a position detection mechanism 5, configured to directly or indirectly detect the position of the leak-proof valve 2.

[0102] The position detection mechanism 5 can directly detect the position of the leak-proof valve 2, and therefore can be positioned along the movement path of the leak-proof valve 2. Since the position of the leak-proof valve 2 corresponds to the state of the drive mechanism 3, the position detection mechanism 5 can also indirectly detect the position of the leak-proof valve 2 by detecting the drive mechanism 3, for example, by detecting the position of the transmission component 32 or the linkage component 33. The position detection mechanism 5 can be mounted on the mounting base 4.

[0103] In one example, the drive slider 321 reciprocates between a starting position and a final position. When the drive slider 321 is in the starting position, the linkage 33 and the leak-proof valve 2 are also in the starting position, at which point the leak-proof valve 2 closes the outlet 111. When the drive slider 321 is in the final position, the linkage 33 and the leak-proof valve 2 are also in the final position, at which point the leak-proof valve 2 opens the outlet 111, and the outflow velocity of the outlet channel 2112 is at its maximum. The position detection mechanism 5 may include a first position sensor and a second position sensor. The first position sensor is configured to detect the drive slider 321 in the starting position, and the second position sensor is configured to detect the drive slider 321 in the final position. The specific form of the position sensor is not limited; it can be a contact sensor, a gradual sensor, or other types of sensors, etc.

[0104] In other examples, the position detection mechanism 5 includes an angle sensor for detecting the rotation angle of the drive motor 311 or the rotation angle of the lead screw 312.

[0105] In some other exemplary embodiments, the leak-proof valve 2 and the drive mechanism 3 are integrated into an electric valve. The electric valve can be, but is not limited to, an electric flow valve. The structure of the electric valve is not limited; it can be a solenoid valve or other types of valves.

[0106] As shown in Figures 1 to 6, this application embodiment also provides a coffee machine, including: a base 300, and a beverage brewing mechanism 100 as described above, which is installed on the base 300.

[0107] The coffee machine provided in this application embodiment has all the above-mentioned beneficial effects because it includes the beverage brewing mechanism 100 of any of the above embodiments, which will not be repeated here.

[0108] In some exemplary embodiments, the coffee machine further includes a control device (not shown in the figure, which may be a main control board), electrically connected to the drive mechanism 3 of the beverage brewing mechanism 100, configured to control the drive mechanism 3 according to a set program, and capable of controlling the start and stop of the drive mechanism 3 and its operating parameters (such as speed, time, power, etc.).

[0109] In this way, the brewing processes for different flavored coffees can be stored in the control device, and the drive mechanism 3 can be automatically controlled by the control device to prepare coffees of different flavors, thereby improving the user experience.

[0110] In some exemplary embodiments, as shown in Figures 1 to 4, the coffee machine also includes a coffee pot 200, which can be placed below the beverage brewing mechanism 100 to hold the coffee dispensed by the beverage brewing mechanism 100. The coffee machine also includes a water filling mechanism 400, which is connected to the brewing chamber 11 and configured to add water to the brewing chamber 11. The outlet of the water filling mechanism 400 can be located above the brewing chamber 11, enabling water to be added to the brewing chamber 11 in the form of a shower head. A control device is also electrically connected to the water filling mechanism 400 and can control the start / stop of the water filling mechanism 400 and its operating parameters (such as temperature, time, flow rate, etc.).

[0111] The coffee machine works as follows:

[0112] As shown in Figures 3 and 5, in the initial state, the drive slider 321, the mating slider 331, the outlet nozzle 332, and the leak-proof valve 2 are all in the starting position. The second sealing element 22 of the leak-proof valve 2 presses against the outlet 111 to close the outlet 111, isolating the outlet 111 from the outlet channel 2112 of the leak-proof valve 2. At this time, the first elastic element 34 and the second elastic element 23 can be in a natural state or a weakly compressed state. The outlet nozzle 332, the mating slider 331, and the leak-proof valve 2 are in the lowest position within their range of motion. The outlet section 3322 of the outlet nozzle 332 is inserted into the second clearance hole 422 of the bottom shell 42, and the limiting boss 421 of the bottom shell 42 is inserted into the clearance groove 3312 of the mating slider 331.

[0113] When a user needs coffee, the water-adding mechanism 400 adds water to the brewing chamber 11. The drive motor 311 actuates, driving the lead screw 312 to rotate. The lead screw 312 drives the drive slider 321 to slide to the left. The drive slider 321 then moves the mating slider 331 and the dispensing nozzle 332 upwards. The dispensing nozzle 332 pushes against the leak-proof valve 2 and moves upwards, causing the second seal 22 to move away from the dispensing port 111, thus opening the dispensing port 111. Simultaneously, the inlet 2111 of the valve stem 211 rises and begins to enter the brewing chamber 11, connecting the dispensing port 111 with the dispensing channel 2112. As the leak-proof valve 2 moves upwards, the portion of the dispensing port 2111 entering the brewing chamber 11 gradually increases, thus gradually increasing the opening area of ​​the dispensing port 2111 and the dispensing flow rate of the dispensing channel 2112. Depending on the user's selection of different coffee flavors, the drive motor 311 rotates at different amplitudes, causing the drive slider 321 to slide at different amplitudes. This, in turn, causes the cooperating slider 331, the dispensing nozzle 332, and the leak-proof valve 2 to rise at different amplitudes, opening the inlet 2111 at different amplitudes, resulting in different dispensing flow rates and producing different flavors of coffee. During the rising process of the cooperating slider 331, the dispensing nozzle 332, and the leak-proof valve 2, the elastic deformation of the first elastic element 34 and the second elastic element 23 gradually increases, as does the compression, storing elastic potential energy.

[0114] When the drive slider 321 slides to the left to its final position (as shown in Figures 4 and 6), the cooperating slider 331, the outlet nozzle 332, and the leak-proof valve 2 also rise to their final positions. At this time, the opening area of ​​the inlet 2111 is at its maximum, and the outflow velocity of the outlet channel 2112 is at its maximum. At this time, the second lip 353 of the first seal 35 is embedded in the second mounting groove 3313. When the cooperating slider 331 rises to its final position, the outlet section 3322 of the outlet nozzle 332 disengages from the second clearance hole 422 of the bottom shell 42, and the limiting boss 421 of the bottom shell 42 disengages from the clearance groove 3312 of the cooperating slider 331.

[0115] When coffee is no longer needed, the outlet 111 needs to be closed, the drive motor 311 rotates in the opposite direction, and the drive slider 321 slides in the opposite direction. With the help of the slider 331, the outlet 332, and the leak-proof valve 2, they can move downward under the action of gravity and the reset elastic force of the first elastic element 34 and the second elastic element 23, and reset to the starting position.
