Description

Technical Field

[0001] The present application relates to but is not limited to the technical field of coffee machines, and specifically refers to a beverage brewing mechanism and a coffee machine. Background Art

[0002] At present, coffee machines are becoming more and more popular among consumers. In the related art, the coffee machine includes a beverage brewing mechanism, coffee raw materials are placed in a brewing chamber of the beverage brewing mechanism, and a container for holding coffee is placed below a liquid outlet of the brewing chamber. Hot water is added to the brewing chamber to extract the coffee raw materials to obtain coffee, and during the extraction process, the coffee enters the container for holding coffee through the liquid outlet. However, the coffee obtained in this way has a single taste and is difficult to meet the taste requirements of different users. Utility Model Content

[0003] The technical problem to be solved by the present application is to provide a beverage brewing mechanism and a coffee machine, which can enrich the flavor of coffee to meet the taste requirements of different users.

[0004] An embodiment of the present application provides a beverage brewing mechanism, comprising: a brewing body, the brewing body being provided with a brewing chamber and a liquid outlet connected to the brewing chamber; a leak-stop valve movably mounted at the liquid outlet and provided with a liquid outlet channel, the liquid outlet channel being configured to be connected to the liquid outlet to discharge the liquid in the brewing body; and a driving mechanism, connected to the leak-stop valve, configured to drive the leak-stop valve to move relative to the brewing body to control the connection between the liquid outlet channel and the liquid outlet and to adjust the liquid outlet flow rate of the liquid outlet channel.

[0005] The beverage brewing mechanism provided in the embodiment of the present application includes a brewing body, a leak-proof valve and a driving mechanism. The brewing body is provided with a brewing chamber and a liquid outlet. The brewing chamber is used to hold 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 enters a container for holding coffee (such as a coffee pot) through the liquid outlet channel of the leak-proof valve for users to drink. The brewing chamber can be funnel-shaped, and the liquid outlet can be set at the bottom of the brewing chamber. Guide ribs can be set on the inner wall surface of the brewing chamber.

[0006] The stop valve is used to control the opening and closing of the liquid outlet. When the liquid outlet channel of the stop valve is connected to the liquid outlet of the brewing chamber, the liquid outlet is opened so that the coffee in the brewing chamber can be discharged. When the liquid outlet channel of the stop valve is disconnected from the liquid outlet of the brewing chamber, the liquid outlet is closed so that the liquid in the brewing chamber cannot be discharged, so as to prevent the brewing chamber from continuing to drip liquid (such as remaining coffee, or remaining water after cleaning the brewing chamber, etc.) after the container containing coffee is removed, causing the table or countertop to be wet.

[0007] The driving mechanism is used to drive the stop-leak valve to move, to adjust the relative position of the stop-leak valve and the brewing body, to realize the opening and closing control of the liquid outlet by the stop-leak valve, and to realize the adjustment of the liquid outlet flow rate. The driving mechanism can be an electric driving mechanism, which is convenient for realizing automatic control of the stop-leak valve, without manual adjustment by the user, which is conducive to improving the user experience.

[0008] In the related art, there is no leak-stop valve at the liquid outlet, or the leak-stop valve has only two states: open and closed. Therefore, the liquid outlet flow rate is constant, and the coffee taste is also single. In the embodiment of the present application, the leak-stop valve can be opened or closed, and closing can achieve the steaming effect of coffee. In addition, the liquid outlet flow rate of the liquid outlet channel can be adjusted, and the liquid outlet flow rate of the liquid outlet channel is related to the concentration of the extracted coffee. When the liquid outlet flow rate is small, the liquid used to extract coffee stays in the brewing chamber for a long time, the extracted coffee concentration is high, and the coffee tastes mellower. When the liquid outlet flow rate is large, the liquid used to extract coffee stays in the brewing chamber for a short time, the extracted coffee concentration is low, and the coffee tastes light. Therefore, by adjusting the liquid outlet flow rate of the liquid outlet channel, the concentration of coffee can be adjusted, so that the coffee has steaming controllability, thereby enriching the flavor of coffee to meet the taste requirements of different users.

[0050] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0051] like Figures 1 to 6 As shown, an embodiment of the present application provides a beverage brewing mechanism 100 , comprising: a brewing body 1 , a leak-stop valve 2 and a driving mechanism 3 .

[0052] The brewing body 1 is provided with a brewing chamber 11 and a liquid outlet 1111 connected to the brewing chamber 11. Figure 5 and Figure 6 shown.

[0053] The leak-proof valve 2 is movably mounted at the liquid outlet 1111 and is provided with a liquid outlet passage 2112. The liquid outlet passage 2112 is configured to be able to communicate with the liquid outlet 1111 to discharge the liquid in the brewing body 1.

[0054] The driving mechanism 3 is connected to the stop-leak valve 2 and is configured to drive the stop-leak valve 2 to move relative to the brewing body 1 to control the connection between the liquid outlet channel 2112 and the liquid outlet 1111 and to adjust the liquid outlet flow rate of the liquid outlet channel 2112 .

[0055] The beverage brewing mechanism 100 provided in the embodiment of the present application includes a brewing body 1, a leak-proof valve 2 and a driving mechanism 3. The brewing body 1 is provided with a brewing chamber 11 and a liquid outlet 1111. The brewing chamber 11 is used to contain 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 1111, and enters a container containing coffee (such as a coffee pot 200) through the liquid outlet channel 2112 of the leak-proof valve 2 for users to drink. The brewing chamber 11 can be funnel-shaped, and the liquid outlet 1111 can be set at the bottom of the brewing chamber 11. The inner wall surface of the brewing chamber 11 can be provided with guide ribs 112.

[0056] The stop valve 2 is used to control the opening and closing of the liquid outlet 1111. When the liquid outlet channel 2112 of the stop valve 2 is connected to the liquid outlet 1111 of the brewing chamber 11, the liquid outlet 1111 is opened. Figure 4 and Figure 6 As shown, the coffee in the brewing chamber 11 can be discharged. When the liquid outlet channel 2112 of the leak-proof valve 2 is disconnected from the liquid outlet 1111 of the brewing chamber 11, the liquid outlet 1111 is closed. Figure 3 and Figure 5 As shown, the liquid in the brewing chamber 11 cannot be discharged, so as to prevent the brewing chamber 11 from continuing to drip liquid (such as remaining coffee, or remaining water after cleaning the brewing chamber 11, etc.) downward after the container containing coffee is taken away, thereby preventing the table or countertop from getting wet.

[0057] The driving mechanism 3 is used to drive the stop-leak valve 2 to move, to adjust the relative position of the stop-leak valve 2 and the brewing body 1, to realize the opening and closing control of the liquid outlet 1111 by the stop-leak valve 2, and to realize the adjustment of the liquid outlet flow rate. The driving mechanism 3 can be an electric driving mechanism 3, which is convenient for realizing automatic control of the stop-leak valve 2, without manual adjustment by the user, which is conducive to improving the user experience.

[0058] In the related art, there is no leak-stop valve at the liquid outlet, or the leak-stop valve has only two states of opening and closing, so the liquid flow rate is constant, and the coffee taste is also single. In the embodiment of the present application, the leak-stop valve 2 can be opened or closed, and closing can achieve the steaming effect of coffee. In addition, the liquid flow rate of the liquid outlet channel 2112 can be adjusted, and the liquid flow rate of the liquid outlet channel 2112 is related to the concentration of the extracted coffee. When the liquid flow rate is small, the liquid used to extract coffee stays in the brewing chamber 11 for a long time, the concentration of the extracted coffee is high, and the coffee tastes mellower. When the liquid flow rate is large, the liquid used to extract coffee stays in the brewing chamber 11 for a short time, the concentration of the extracted coffee is low, and the coffee tastes light. Therefore, by adjusting the liquid flow rate of the liquid outlet channel 2112, the concentration of coffee can be adjusted, so that the coffee has steaming controllability, thereby enriching the flavor of coffee to meet the taste requirements of different users.

[0059] 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, such as Figure 5 , Figure 6 and Figure 7 The liquid inlet 2111 allows liquid such as coffee in the brewing chamber 11 to enter the liquid outlet channel 2112 .

[0060] The valve core 21 is configured to be movably installed at the liquid outlet 1111 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 between the liquid outlet channel 2112 and the liquid outlet 1111 and adjusting the liquid outlet flow rate of the liquid outlet channel 2112.

[0061] The driving 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 .

[0062] When the liquid inlet 2111 of the leak-proof valve 2 is connected to the liquid outlet 1111 of the brewing chamber 11, the coffee or other liquid in the brewing chamber 11 can enter the liquid outlet channel 2112, and the liquid outlet 1111 of the brewing chamber 11 is connected to the liquid outlet channel 2112. When the liquid inlet 2111 of the leak-proof valve 2 is disconnected from the liquid outlet 1111 of the brewing chamber 11, the coffee or other liquid in the brewing chamber 11 cannot enter the liquid outlet channel 2112, and the liquid outlet 1111 of the brewing chamber 11 is isolated from the liquid outlet channel 2112.

[0063] By controlling the movement amplitude of the leak-stop valve 2 relative to the brewing body 1, the opening area of ​​the liquid inlet 2111 can be adjusted, and then the liquid flow entering the liquid outlet channel 2112 can be adjusted, thereby achieving the regulation of the liquid outlet flow rate.

[0064] Of course, the movement form of the leak-stop valve 2 is not limited to the moving form. For example, it may also include a rotation form. By rotating the leak-stop valve 2, the opening area of ​​the liquid inlet 2111 can be adjusted, and then the liquid flow rate entering the liquid outlet channel 2112 can be adjusted, thereby achieving the adjustment of the liquid outlet flow rate; it may also include both rotation and movement. By rotating and moving the leak-stop valve 2, the opening area of ​​the liquid inlet 2111 can be adjusted, and then the liquid flow rate entering the liquid outlet channel 2112 can be adjusted, thereby achieving the adjustment of the liquid outlet flow rate.

[0065] In some exemplary embodiments, the driving mechanism 3 includes: a driving member 31 and a transmission assembly. The driving member 31 is connected to the transmission assembly and is configured to drive the transmission assembly to move. The transmission assembly is connected to the valve core 21 and is configured to drive the valve core 21 to move relative to the brewing body 1.

[0066] The transmission assembly includes a transmission member 32 and a linkage member 33. The transmission member 32 is connected to the driving member 31 and is configured to move in a first direction under the drive of the driving member 31. The linkage member 33 cooperates with the transmission member 32 and the valve core 21 and is configured to move in a second direction under the drive of the transmission member 32, so as to drive the valve core 21 to move in the second direction relative to the brewing body 1. The second direction is different from the first direction.

[0067] This makes it easy to reasonably select the type of the driving member 31 and arrange the position of the driving member 31 according to needs, which is conducive to optimizing the structure and layout of the beverage brewing mechanism 100.

[0068] In some exemplary embodiments, the transmission member 32 includes a driving slider 321, such as Figure 5 , Figure 6 , Figures 9 to 11 The driving slider 321 is configured to slide along the first direction under the drive of the driving member 31. The driving slider 321 is provided with a driving inclined surface 3212, as shown in FIG. Figure 5 , Fig.10 and Fig.13 The linkage 33 is provided with a matching inclined surface 3311, as shown in FIG. Figure 5 and Fig.11 The driving inclined surface 3212 is configured to fit with the matching inclined surface 3311 to drive the linkage member 33 to move along the second direction.

[0069] In other words, the transmission member 32 and the linkage member 33 cooperate with each other through the wedge-shaped inclined surfaces to 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 may be perpendicular to the first direction.

[0070] Of course, the matching form of the transmission member 32 and the linkage member 33 is not limited to this. For example, the transmission member 32 can be a gear, and the linkage member 33 can be a rack. The gear rotates in the first direction to drive the rack to move in the second direction, and the rack drives the valve core 21 to move in the second direction.

[0071] In some exemplary embodiments, the linkage 33 includes a matching slider 331 and a liquid outlet 332 disposed on the matching slider 331. Figure 5 , Fig.14 and Fig.15 The matching slider 331 is provided with a matching inclined surface 3311. The second direction is the axial direction of the liquid outlet 1111. The liquid outlet nozzle 332 is connected to the liquid outlet channel 2112 and abuts against the bottom of the valve core 21, as shown in FIG. Figure 5 and Figure 6 The axial direction of the liquid outlet 1111 is usually a vertical direction, so the second direction is a vertical direction. The first direction can be a horizontal direction.

[0072] In this way, after the coffee (or other liquid) in the brewing chamber 11 is discharged through the liquid outlet channel 2112 of the leak-proof valve 2, it can be discharged downward through the liquid outlet nozzle 332. This is conducive to the smooth discharge of coffee into the container for holding coffee, and is conducive to avoiding the setting of the transmission component affecting the smooth discharge of coffee.

[0073] In some exemplary embodiments, the valve core 21 includes a valve stem 211, such as Figure 5 and Figure 7 The valve stem 211 is inserted into the liquid outlet 1111 along the second direction. The liquid inlet 2111 is arranged on the side wall of the valve stem 211 , and the liquid outlet channel 2112 is arranged in the valve stem 211 .

[0074] like Figure 5 and Figure 7 As shown, the valve core 21 further 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 a liquid discharge port 2122 is provided at the bottom of the receiving groove 2121. The top of the liquid outlet nozzle 332 abuts against the abutment portion 212, and the liquid outlet nozzle 332 is also connected to the liquid discharge port 2122.

[0075] like Figure 3 and Figure 5 As shown in FIG. 1 , when the leak-proof valve 2 is in a position to disconnect the liquid outlet channel 2112 from the liquid outlet 1111, the liquid inlet 2111 is located outside the brewing chamber 11 and is in a closed state. When the leak-proof valve 2 moves upward, the liquid inlet 2111 moves upward. When the liquid inlet 2111 begins to enter the brewing chamber 11, it can be connected with the liquid outlet 1111 and is in an open state. Figure 4 and Figure 6The upward movement degree of the valve core 21 is different, and the area of ​​the liquid inlet 2111 entering the brewing chamber 11 is different, so the opening area of ​​the liquid inlet 2111 is different.

[0076] There may be multiple liquid inlets 2111. The multiple liquid inlets 2111 may be spaced apart along the circumference of the valve core 21, the multiple liquid inlets 2111 may be spaced apart along the axial direction of the valve core 21, or the multiple liquid inlets 2111 may be spaced apart along the circumference and axial direction of the valve core 21.

[0077] The arrangement of the receiving groove 2121 facilitates the coffee in the gap between the valve stem 211 and the liquid outlet 1111 to enter the receiving groove 2121, and then be discharged into the liquid outlet nozzle 332 through the liquid discharge port 2122 of the receiving groove 2121, thereby preventing the liquid leaking from the gap between the valve core 21 and the liquid outlet 1111 from spilling everywhere. The number of the liquid discharge ports 2122 can be multiple, and the multiple liquid discharge ports 2122 can be arranged at intervals along the circumference of the receiving groove 2121.

[0078] In some exemplary embodiments, Figure 5 As shown, the leak-proof valve 2 further includes: a second sealing member 22, which is mounted on the valve core 21 and is configured to seal the liquid outlet 1111 when the leak-proof valve 2 is in a position where the liquid outlet 1111 is disconnected from the liquid outlet channel 2112. The outer diameter of the second sealing member 22 can be larger than the diameter of the liquid outlet 1111, and the outer diameter of at least a portion of the valve stem 211 can be smaller than the diameter of the liquid outlet 1111. In this way, the valve stem 211 can move up and down along the liquid outlet 1111, and when the second sealing member 22 abuts against the liquid outlet 1111, the liquid outlet 1111 can be closed and sealed. Figure 5 The second sealing member 22 is located inside the brewing chamber 11 and closes the liquid outlet 1111 when it moves downward to the final position.

[0079] like Figure 5 and Figure 6 As shown, the beverage brewing mechanism 100 further includes: a second elastic member 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 1111 and the liquid outlet channel 2112. This is conducive to the leak-proof valve 2 to stably stay in the position of closing the liquid outlet 1111. Of course, the leak-proof valve 2 may also not include the second elastic member 23, and use the gravity of the leak-proof valve 2 to stay in the position of closing the liquid outlet 1111.

[0080] The abutment portion 212 of the valve core 21 can also be used to cooperate with the second elastic member 23. The second elastic member 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 can abut against the brewing body 1 and be located on the outside of the brewing chamber 11. During the upward movement of the valve core 21, the second elastic member 23 is compressed to store elastic potential energy. During the downward movement of the valve core 21, the second elastic member 23 releases elastic potential energy and provides a downward movement force to the valve core 21, which is beneficial for the valve core 21 to stably maintain the position of closing the liquid outlet 1111. The abutment portion 212 and the valve stem 211 can be an integrated structure or a split assembly structure.

[0081] The second sealing member 22 may be a sealing ring. The valve stem 211 may be provided with a sealing groove 2113, such as Figure 5 and Figure 7 As shown, the second sealing member 22 is sleeved in the sealing groove 2113. When the leak-proof valve 2 moves downward to the position of closing the liquid outlet 1111, the second sealing member 22 abuts against the inner bottom wall of the brewing chamber 11 to seal the liquid outlet 1111. Figure 5 During installation, the top of the valve stem 211 can be passed through the liquid outlet 1111 from bottom to top, and then the second sealing member 22 can be mounted on the valve stem 211 from top to bottom. After loosening, the leak-stop valve 2 can be stably in a position to close the liquid outlet 1111 under the action of gravity and the second elastic member 23.

[0082] In some embodiments, Figure 3 and Figure 4 As shown, the brewing body 1 includes a brewing cup and a base. The brewing cup includes a brewing chamber 11 and a cup shell 12 sleeved on the outside of the brewing chamber 11. The brewing chamber 11 and the cup shell 12 can be an integrated structure or a split assembly structure. A liquid outlet 1111 is provided at the bottom of the brewing chamber 11. The base is sleeved on the inner side of the bottom of the cup shell 12 and is fixedly connected to the brewing cup. The base is provided with an avoidance space corresponding to the liquid outlet 1111, as shown in FIG. Figure 5 and Figure 6 The part of the leak-proof valve 2 outside the brewing chamber 11 can be hidden in the avoidance space. The outer bottom wall of the brewing chamber 11 is provided with a first hollow column 114 and a second hollow column 115 which are nested. Figure 5 As shown, the inner space of the first hollow column 114 is connected to the liquid outlet 1111. The first hollow column 114 and the second hollow column 115 are also located in the avoidance space. The valve stem 211 is inserted into 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 step groove 113, as shown in FIG. Figure 5As shown. When the leak-proof valve 2 moves downward to the position of closing the liquid outlet 1111, the second sealing member 22 is located in the step 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 coffee to smoothly enter the liquid outlet channel 2112 and the receiving groove 2121.

[0083] In some exemplary embodiments, Figure 2 As shown, the beverage brewing mechanism 100 further includes: a mounting seat 4, and the driving mechanism 3 is mounted on the mounting seat 4. The mounting seat 4 is provided with a slide groove 44 extending along the first direction and a guide hole 411 extending along the second direction. The driving slider 321 is limited in the slide groove 44 and is configured to slide along the slide groove 44. The liquid outlet nozzle 332 is penetrated by the guide hole 411 and is configured to move along the guide hole 411.

[0084] The mounting seat 4 can serve as a mounting carrier for the driving mechanism 3 , supporting and protecting the driving mechanism 3 , and can also guide and limit the driving slider 321 and the liquid outlet nozzle 332 , which is beneficial to improving the reliability of the driving mechanism 3 .

[0085] In some exemplary embodiments, Figure 5 and Figure 6 As shown, the mounting seat 4 includes: a bottom shell 42 and a cover shell 41. The cover shell 41 is connected to the bottom shell 42 and encloses a mounting cavity 43 with the bottom shell 42. Figure 6 As shown, the slide groove 44 is arranged in the installation cavity 43. The guide hole 411 is arranged in the cover shell 41. At least a part of the driving mechanism 3 is located in the installation cavity 43.

[0086] In this way, the mounting seat 4 can provide better protection for the driving mechanism 3 and is also beneficial to improving the simplicity of the appearance of the beverage brewing mechanism 100, thereby improving the aesthetics of the product.

[0087] The bottom shell 42 and the cover shell 41 can be processed and formed separately, which is conducive to reducing the difficulty of processing. The bottom shell 42 and the cover shell 41 can be fixed together by screwing, riveting, clamping, plugging, etc. The cover shell 41 can be provided with two first guide ribs, and a slide groove 44 is formed between the two first guide ribs. The bottom shell 42 can be provided with two second guide ribs 423, such as Fig. 9 As shown, a slide groove 44 is formed between the two first guide ribs. The first guide rib and the second guide rib 423 can be arranged to abut each other, or can be matched with a stop. In this way, the bottom shell 42 and the cover shell 41 can both play a limiting and guiding role on the driving slider 321. Stoppers 441 can be set at both ends of the slide groove 44, such as Fig. 9 As shown, the starting position and the final position of the driving slider 321 are limited.

[0088] like Figure 5 and Figure 8 As shown, the cover shell 41 can be provided with a limiting groove 414, and the first sealing member 35 can be a sealing ring. The first sealing member 35 is partially limited in the limiting groove 414 and is sleeved between the portion of the liquid outlet nozzle 332 inserted into the guide hole 411 and the hole wall of the guide hole 411.

[0089] In some exemplary embodiments, the driving slider 321 and the mating slider 331 are both located in the mounting cavity 43 .

[0090] The liquid outlet nozzle 332 penetrates the matching slider 331 along the second direction. Figure 5 , Fig.14 and Fig.15 As shown, the liquid outlet nozzle 332 includes a liquid inlet section 3321 located on the side of the matching slider 331 close to the stop valve 2 (i.e., the upper side) and a liquid outlet section 3322 located on the side of the matching slider 331 away from the stop valve 2 (i.e., the lower side). The bottom of the liquid outlet section 3322 may be provided with a plurality of outlets at intervals along the circumferential direction. The liquid inlet section 3321 is provided through the guide hole 411.

[0091] The liquid outlet nozzle 332 and the matching slider 331 may be an integrated structure or a split assembly structure. Figure 5 As shown, the liquid outlet nozzle 332 can be set to a stepped structure, and the flow area of ​​the liquid inlet section 3321 is larger than the flow area of ​​the liquid outlet section 3322. In other words, the liquid inlet section 3321 is thicker to ensure that the coffee in the liquid outlet channel 2112 and the receiving groove 2121 can smoothly enter the liquid outlet nozzle 332; the liquid outlet section 3322 is thinner, which is conducive to the smooth entry of the coffee into the container for holding coffee and avoids spilling. Figure 5 and Fig.15 As shown, the liquid outlet nozzle 332 may further include a transition section 3323 between the liquid inlet section 3321 and the liquid outlet section 3322 . The transition section 3323 may be configured to be funnel-shaped to facilitate the coffee to be collected and enter the liquid outlet section 3322 .

[0092] The driving slider 321 is provided with a first avoidance hole 3211 for avoiding the liquid outlet section 3322. Fig. 9 , Fig.10 , Fig.11 and Fig.13 The first avoidance hole 3211 may penetrate an end of the driving slider 321 away from the driving member 31 along the first direction.

[0093] The bottom shell 42 is provided with a second avoidance hole 422 corresponding to the liquid outlet section 3322. Figure 5 As shown, based on the separation of the liquid outlet channel 2112 from the liquid outlet port 1111, the liquid outlet section 3322 is arranged through the second avoidance hole 422. The second avoidance hole 422 can be a circular hole.

[0094] In some exemplary embodiments, an annular avoidance groove 3312 is provided at the bottom of the matching slider 331. Figure 5 , Fig.11 and Fig.14 As shown, the avoidance groove 3312 is sleeved on the outer side of the liquid outlet section 3322. The bottom shell 42 is provided with an annular limiting boss 421, as shown in FIG. Figure 5 As shown, the limiting boss 421 surrounds the second avoidance hole 422. Based on the separation of the liquid outlet channel 2112 and the liquid outlet 1111, the limiting boss 421 is embedded in the avoidance groove 3312, as shown in FIG. Figure 5 This is helpful to improve the position stability of the liquid outlet nozzle 332 and the matching slider 331 when the liquid outlet 1111 is closed.

[0095] In some exemplary embodiments, the driving mechanism 3 further includes: a first elastic member 34 and a first sealing member 35, such as Figure 5 and Figure 6 shown.

[0096] The first elastic member 34 cooperates with the linking member 33 and is configured to use its restoring elastic force to drive the linking member 33 to move in the second direction away from the valve core 21. The top surface of the matching slider 331 can be provided with a limiting groove 3314, such as Figure 5 and Fig.15 The first elastic member 34 may be a spring, which is sleeved on the outside of the liquid inlet section 3321 of the liquid outlet nozzle 332. The lower end of the first elastic member 34 is embedded in the limiting groove 3314 of the matching slider 331. The upper end of the first elastic member 34 abuts against the cover shell 41 and may be sleeved on the outside of the limiting step 415 of the cover shell 41 described below. The limiting groove 3314 may be located radially outside the second mounting groove 3313.

[0097] like Figure 6 As shown, the first sealing member 35 is sleeved between the liquid outlet nozzle 332 and the guide hole 411 , and is configured to seal the gap between the liquid outlet nozzle 332 and the guide hole 411 .

[0098] During the upward movement of the linking member 33, the first elastic member 34 is compressed to store elastic potential energy. During the downward movement of the linking member 33, the first elastic member 34 releases elastic potential energy to provide a downward force to the linking member 33, which helps the linking member 33 to stably maintain a position against the bottom shell 42.

[0099] Of course, the driving mechanism 3 may also not include the first elastic member 34 , and utilize the gravity of the linking member 33 to maintain the position against the bottom shell 42 .

[0100] In some examples, such as Figure 5As shown, the first sealing member 35 includes an annular sealing body 351 and a first lip 352 and a second lip 353 respectively provided at two axial ends of the sealing body 351. The first lip 352 and the second lip 353 both extend radially outwardly along the sealing body 351. The outer top wall of the cover shell 41 is concavely provided with a first mounting groove, such as Figure 5 and Figure 8 As shown, the first lip 352 is limited in the first installation groove. The top wall of the cover shell 41 can be provided with a limiting step 415 protruding downward, such as Figure 5 As shown, the second lip 353 abuts against the lower end surface of the limiting step 415. The upper surface of the matching slider 331 may be concavely provided with a second mounting groove 3313, such as Figure 5 and Fig.15 As shown, the second installation groove 3313 is used to cooperate with the second lip 353. When the valve core 21 moves upward to the final position, the second lip 353 is embedded in the second installation groove 3313, as shown in FIG. Figure 6 As shown, the final position of the liquid outlet nozzle 332 is positioned.

[0101] In some exemplary embodiments, Figure 5 , Figure 6 and Fig.12 As shown, the driving member 31 includes: a driving motor 311 and a screw rod 312 connected to the driving motor 311. A threaded hole is provided in the driving slider 321, and the screw rod 312 is connected to the threaded hole by threads.

[0102] The driving motor 311 drives the screw rod 312 to rotate, and the screw rod 312 drives the driving slider 321 to slide along the first direction. The screw rod 312 can be a single-head screw rod 312, or a double-head screw rod 312 or a multi-head screw rod 312. By adjusting the rotation amplitude of the driving motor 311, the rotation amplitude of the screw rod 312 can be adjusted, thereby increasing the sliding amplitude of the entire driving slider 321, and then adjusting the lifting amplitude of the linkage 33 and the leak-proof valve 2.

[0103] The driving member 31 may further include a gear transmission mechanism between the driving motor 311 and the lead screw 312 , so as to facilitate adjustment of the transmission ratio.

[0104] like Figure 8 and Fig. 9 As shown, the driving mechanism 3 may further include a connector 36 electrically connected to the driving motor 311. The mounting seat 4 may be provided with a mounting notch 413, such as Figure 8 As shown, the connector 36 can extend out of the mounting base 4 through the mounting notch 413, so as to be electrically connected to the main control board in the coffee machine base 300. The base 300 can be provided with a connector 36, and the electrical connection between the driving mechanism 3 and the main control board can be realized through the docking of the connector 36, so that the main control board can control the driving mechanism 3.

[0105] In some exemplary embodiments, a mounting countersunk hole 3213 is provided in the driving slider 321. Fig.13 A nut 322 is provided in the mounting counterbore 3213. Figure 5 and Figure 6 As shown, the nut 322 is provided with a threaded hole. The driving slider 321 is also provided with a third avoidance hole 3214 connected to the threaded hole. Figure 5 As shown, the third avoidance hole 3214 is configured to avoid the portion of the screw rod 312 passing through the nut 322. This is beneficial to simplifying the structure of the driving slider 321 and facilitating the processing and forming of the driving slider 321.

[0106] The nut 322 can be fixedly connected to the driving slider 321 by means of screw connection, riveting, clamping, etc. For example, the mounting nut 322 is provided with two holes, through which two screws 323 (such as Fig.10 The nut 322 is fixedly connected to the driving slider 321. The nut 322 can also be integrally formed with the driving slider 321 through a process such as overmolding.

[0107] In some exemplary embodiments, Fig. 9 and Fig.10 As shown, the beverage brewing mechanism 100 further includes: a position detection mechanism 5 , which is configured to directly or indirectly detect the position of the leak-stop valve 2 .

[0108] The position detection mechanism 5 can directly detect the position of the stop-leak valve 2, and the position detection mechanism 5 can be set on the movement path of the stop-leak valve 2. Since the position of the stop-leak valve 2 corresponds to the state of the driving mechanism 3, the position detection mechanism 5 can also indirectly detect the position of the stop-leak valve 2 by detecting the driving mechanism 3, for example, by detecting the position of the transmission member 32 or the linkage member 33 to indirectly detect the position of the stop-leak valve 2. The position detection mechanism 5 can be installed on the mounting seat 4.

[0109] In one example, the driving slider 321 slides back and forth between the starting position and the final position. When the driving slider 321 is in the starting position, the linkage 33 and the leak-proof valve 2 are also in the starting position, and the leak-proof valve 2 closes the liquid outlet 1111. When the driving slider 321 is in the final position, the linkage 33 and the leak-proof valve 2 are also in the final position, and the leak-proof valve 2 opens the liquid outlet 1111, and the liquid outlet flow rate of the liquid outlet channel 2112 is the 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 driving slider 321 in the starting position, and the second position sensor is configured to detect the driving slider 321 in the final position. The specific form of the position sensor is not limited, and it may be a contact sensor, an asymptotic sensor, or other types of sensors.

[0110] In other examples, the position detection mechanism 5 includes an angle sensor, and the angle sensor is used to detect the rotation angle of the drive motor 311 or to detect the rotation angle of the lead screw 312 .

[0111] In other exemplary embodiments, the leak-stop valve 2 and the drive mechanism 3 are integrated into an electric valve. The electric valve may be, but is not limited to, an electric flow valve. The structure of the electric valve is not limited, and may be a solenoid valve or other types of valves.

[0112] like Figures 1 to 6 As shown, an embodiment of the present application further provides a coffee machine, comprising: a machine base 300 , such as a beverage brewing mechanism 100 as described above, installed on the machine base 300 .

[0113] The coffee machine provided in the embodiment of the present application includes the beverage brewing mechanism 100 of any one of the above embodiments, and thus has all the above-mentioned beneficial effects, which will not be described in detail here.

[0114] In some exemplary embodiments, the coffee machine also includes: a control device (not shown in the figure, which can be a main control panel), which is electrically connected to the driving mechanism 3 of the beverage brewing mechanism 100, and is configured to control the driving mechanism 3 according to a set program, and can control the start and stop of the driving mechanism 3 and working parameters (such as speed, time, power, etc.).

[0115] In this way, the brewing programs of coffees with different flavors can be stored in the control device, and the drive mechanism 3 can be automatically controlled by the control device to prepare coffees with different flavors, thereby helping to improve the user experience.

[0116] In some exemplary embodiments, Figures 1 to 4 As shown, the coffee machine further includes a coffee pot 200, which can be placed below the beverage brewing mechanism 100 and is used to hold the coffee discharged by the beverage brewing mechanism 100. The coffee machine further includes a water adding mechanism 400, which is connected to the brewing chamber 11 and is configured to add water to the brewing chamber 11. The water outlet of the water adding mechanism 400 can be located above the brewing chamber 11, and water can be added to the brewing chamber 11 in the form of a shower. The control device is also electrically connected to the water adding mechanism 400, and can control the start and stop of the water adding mechanism 400 and the working parameters (such as temperature, time, flow, etc.).

[0117] The working principle of this coffee machine is as follows:

[0118] like Figure 3 and Figure 5As shown, in the initial state, the driving slider 321, the matching slider 331, the liquid outlet nozzle 332, and the leak-proof valve 2 are all located at the starting position, and the second sealing member 22 of the leak-proof valve 2 presses the liquid outlet 1111 to close the liquid outlet 1111 and separate the liquid outlet 1111 from the liquid outlet channel 2112 of the leak-proof valve 2. At this time, the first elastic member 34 and the second elastic member 23 can be in a natural state or a weakly compressed state. The positions of the liquid outlet nozzle 332, the matching slider 331, and the leak-proof valve 2 are at the lowest position within the range of motion. The liquid outlet section 3322 of the liquid outlet nozzle 332 is inserted into the second avoidance hole 422 of the bottom shell 42, and the limiting boss 421 of the bottom shell 42 is inserted into the avoidance groove 3312 of the matching slider 331.

[0119] When the user needs coffee, the water adding mechanism 400 adds water to the brewing chamber 11, the driving motor 311 is activated, the screw rod 312 is driven to rotate, the screw rod 312 drives the driving slider 321 to slide to the left, the driving slider 321 drives the matching slider 331 and the liquid outlet nozzle 332 to move upward, the liquid outlet nozzle 332 moves upward against the leak-proof valve 2, so that the second sealing member 22 leaves the liquid outlet 1111 to open the liquid outlet 1111, and the liquid inlet 2111 of the valve stem 211 rises and begins to enter the brewing chamber 11, thereby achieving the connection between the liquid outlet 1111 and the liquid outlet channel 2112. As the leak-proof valve 2 moves upward, the portion of the liquid inlet 2111 entering the brewing chamber 11 gradually increases, the opening area of ​​the liquid inlet 2111 gradually increases, and the liquid outlet flow rate of the liquid outlet channel 2112 gradually increases. According to the different coffee flavors selected by the user, the driving motor 311 rotates at different amplitudes, so that the driving slider 321 can slide at different amplitudes, driving the matching slider 331, the liquid outlet nozzle 332, and the leak-proof valve 2 to rise at different amplitudes, and the liquid inlet 2111 opens at different amplitudes, forming different liquid outlet flow rates, and producing coffee with different flavors. In the process of the matching slider 331, the liquid outlet nozzle 332, and the leak-proof valve 2 rising, the elastic deformation amount of the first elastic member 34 and the second elastic member 23 gradually increases, and the compression amount gradually increases, and the elastic potential energy is stored.

[0120] When the driving slider 321 slides to the left to the final position (such as Figure 4 and Figure 6 As shown in the figure, the matching slider 331, the liquid outlet nozzle 332, and the leak-proof valve 2 also rise to the final position. At this time, the opening area of ​​the liquid inlet 2111 is the largest, and the liquid outlet flow rate of the liquid outlet channel 2112 is the largest. At this time, the second lip edge 353 of the first sealing member 35 is embedded in the second mounting groove 3313. The matching slider 331 rises to the final position, so that the liquid outlet section 3322 of the liquid outlet nozzle 332 escapes from the second avoidance hole 422 of the bottom shell 42 and the limiting boss 421 of the bottom shell 42 escapes from the avoidance groove 3312 of the matching slider 331.

[0121] When coffee is not needed, the liquid outlet 1111 needs to be closed, and the driving motor 311 rotates in the opposite direction, driving the driving slider 321 to slide in the opposite direction. The slider 331, the liquid outlet nozzle 332, and the leak-stop valve 2 can move downward under the action of gravity and the restoring elastic force of the first elastic member 34 and the second elastic member 23, and reset to the starting position.
