[0046] See also Figures 1 to 7 The utility model provides a brewing module, which is used in a beverage preparation device.

[0047] In view of this, the present invention also provides a beverage preparation device. The specific form of the beverage preparation device is not limited, such as a common coffee machine, soybean milk machine, food processor, etc.

[0048] The beverage preparation device includes a housing and a brewing module. According to actual needs, the beverage preparation device may also be integrated with other required functions, such as a grinding module, a weighing module, a cleaning module, a liquid supply module, a milk supply module, a heating module, and a cooling module.

[0049] It can be understood that the housing generally has a receiving cavity formed inside. The brewing module is at least partially received in the receiving cavity. Figures 1 to 3 In this embodiment, the brewing module includes a container assembly 100 and a driving device 200 . The container assembly 100 comprises a brewing container 110 and a lower piston member 120, wherein the brewing container 110 is movably arranged in the transverse direction to have a powder receiving position 310 and a brewing position 320, the brewing container 110 is provided with a channel 111 in the vertical direction, and the lower piston member 120 is reciprocatingly mounted on the channel 111 in the vertical direction; the driving device 200 comprises a movable member 210 and a guide member 220, the movable member 210 moves up and down in the vertical direction respectively and is rotatably arranged around a vertical axis, the movable member 210 is linked with the lower piston member 120, one of the movable member 210 and the guide member 220 is provided with a guide groove 211, and the other is provided with a guide protrusion 221, the guide groove 211 comprises a vertical groove section 211c and two transverse groove sections extending transversely from the upper and lower ends of the vertical groove section 211c, and the two transverse groove sections are both located on the same side of the vertical groove section 211c in the transverse direction;

[0050] The relative displacement between the guide protrusion 221 and the transverse groove section drives the brewing container 110 to rotate transversely, and the relative displacement between the guide protrusion 221 and the vertical groove section 211 c drives the lower piston to move up and down in the brewing container 110 .

[0051] In the technical solution provided by the present invention, when the guide protrusion 221 is initially at the second end of a transverse groove section, the container assembly 100 is in the powder receiving position 310 as a whole, and operations such as grinding out powder and transferring powder can be performed according to actual needs; then when the movable member 210 rotates and translates in one direction, driving the guide protrusion 221 to move along the transverse groove section from the second end to the first end, the movable member 210 and the guide member 220 mainly have a relative displacement in the transverse direction, and the brewing container 110 and the lower piston are driven to move to the brewing position 320 together; then when the movable member 210 Continuing to move in the same direction and in translation, the guide protrusion 221 is driven to move along the vertical groove section 211c, and the lower piston moves up and down relative to the brewing container 110, completing the pressing of the powder contained in the brewing container 110 into cakes, extraction and upper slag discharge operations; finally, when the movable part 210 rotates and translates, driving the guide protrusion 221 to move along another horizontal groove section from the first end to the second end, the movable part 210 and the guide part 220 also have a relative displacement in the horizontal direction, and the brewing container 110 and the lower piston are driven together to move to the powder receiving position 310, completing a whole brewing cycle. The utility model only needs to divide the guide groove 211 into three groove sections to complete all necessary operations of the container assembly 100. It has the characteristics of simple structure and easy operation. The three groove sections do not form a closed loop, which helps to reduce the number and angle of reversals of the guide protrusion 221 in the guide groove 211, thereby greatly increasing the smoothness of the movement of the guide protrusion 221 in the guide groove 211, avoiding abnormalities such as movement jamming, and ultimately helping to optimize the overall driving effect of the driving device 200.

[0052] It should be noted that the horizontal and vertical directions involved in this embodiment are set to be two relative directions that intersect each other at approximately 90 degrees. For ease of understanding, in the following embodiments, the vertical direction is specifically the gravity direction, that is, the up and down direction. The horizontal direction is specifically any direction on the horizontal plane.

[0053] In the present design, the brewing module used in the beverage preparation device may further include a base 300. The base 300 may be provided for the installation of the container assembly 100 and the driving device 200. It is understood that the base 300 may be a plate-like structure, a block-like structure, a box-like structure, a frame-like structure, or other suitable structures for installation of, for example, the container assembly 100 and the driving device 200, which are dedicated to the brewing module. Alternatively, the base 300 may also be a structure at least partially defined by, for example, a housing of the beverage preparation device, or a structure at least partially defined by other components (such as a grinding module) in the beverage preparation device, without limitation.

[0054] The base 300 can predefine a powder receiving position 310 and a brewing position 320 according to the movement trajectory of the container assembly 100, and the powder receiving position 310 and the brewing position 320 are roughly spaced apart in the horizontal direction. A grinding module or a storage box for storing coffee powder can be preset in the beverage preparation device. Taking the grinding module as an example, at least the discharge port of the grinding module is arranged at the powder receiving position 310. The beverage preparation device can also preset an upper piston member 410 movably arranged in the vertical direction at the brewing position 320, and a pressing drive mechanism 420 for driving the upper piston member 410 to move. At least the upper piston member 410 is arranged at the brewing position 320. The container assembly 100 as a whole can be reciprocated between the powder receiving position 310 and the brewing position 320:

[0055] When the coffee powder receiving position 310 is reached, the discharge port of the grinding module (or the discharge port of the external coffee powder preset in the housing) and the feed port of the brewing container 110 are arranged from top to bottom, so that the coffee powder can automatically fall into the channel 111 under the action of gravity. At this time, the lower piston 120 forms the bottom of the brewing container 110 and can receive the coffee powder in the channel 111.

[0056] When moving to the brewing position 320, the upper piston member 410 is located vertically above the brewing container 110. When the upper piston member 410 and the lower piston member 120 are close to each other, the coffee powder received by the lower piston member 120 can be pressed to obtain a powder cake, which is convenient for subsequent extraction operations.

[0057] In view of the above, the driving device 200 needs to achieve the purpose of driving the container assembly 100 to move horizontally as a whole, and driving the lower piston 120 to move up and down relative to the brewing container 110:

[0058] The movable member 210 is generally a long rod-shaped or shaft-shaped structure extending in the vertical direction. The transverse cross-sectional shape of the movable member 210 is not limited, but in order to increase the smoothness of rotation, the transverse cross-sectional shape of the movable member 210 is generally set to be circular.

[0059] Specifically in one embodiment, the guide member 220 is fixedly arranged and sleeved on the outer side of the movable member 210 in a cylindrical shape. The guide member 220 is, for example, directly or indirectly fixedly installed on the above-mentioned base 300. There is no limitation on the fixed connection method between the two, and they can be, for example, integrally formed, or they can be detachably or non-detachably connected and fixed after being separately formed. The guide member 220 is sleeved on the outer side of the movable member 210 in a cylindrical shape, so that the above-mentioned guide protrusion 221 and guide groove 211 can be provided between the entire outer side wall of the movable member 210 and the entire inner side wall of the guide member 220, and sufficient space is reserved for the structural design of the guide groove 211.

[0060] When the guide member 220 is fixed relative to the base 300, the moving track of the guide protrusion 221 along the guide groove 211 is directly converted into the moving track of the guide member 220. Since the movable member 210 is linked with the lower piston member 120, the moving track of the guide member 220 can be directly converted into the moving track of the lower piston member 120, so that the lateral displacement and the up and down movement of the lower piston member 120 are realized.

[0061] In one embodiment, the brewing container 110 is disposed beside the movable member 210 and is rotatable around the rotation axis of the movable member 210. Thus, when the movable member 210 rotates around the vertical axis, the lower piston member 120 linked thereto can drive the brewing container 110 to revolve around the vertical axis, thereby achieving the purpose of active switching of the brewing container 110 and the lower piston member 120 between the powder receiving position 310 and the brewing position 320.

[0062] In view of the above, it can be known that when the brewing container 110 and the movable member 210 are arranged at intervals in the transverse direction, and the guide member 220 is cylindrical and sleeved on the outer side of the movable member 210, the driving device 200 further includes a linkage sleeve 270, a linkage vertical rod 281 and a linkage horizontal rod 282. The linkage sleeve 270 is formed with a first sleeve 271 and a second sleeve 272 sequentially connected in the transverse direction, the first sleeve 271 is movably sleeved on the outer side of the guide member 220, and the second sleeve 272 is fixedly sleeved on the outer side of the brewing container 110; the linkage vertical rod 281 and the movable member 210 are arranged side by side in the transverse direction, and the linkage vertical rod 281 is connected to the lower piston member 120; the linkage horizontal rod 282 extends in the transverse direction and connects the movable member 210 and the linkage vertical rod 281.

[0063] It can be understood that the linkage sleeve 270 can realize the rotation of the container assembly 100 relative to the guide member 220. And according to actual needs, the linkage sleeve 270 can be configured to have functions such as heat insulation and shock absorption. For example, the brewing container 110 is made of ceramic material. The ceramic material has good rigidity and hardness, and is more wear-resistant, which helps to increase the service life of the brewing container 110; in addition, the ceramic material has good thermal resistance, which can reduce the heat exchange between the coffee beverage in the channel 111 and the external environment during the extraction and brewing process, avoid causing the coffee beverage to cool down, and reduce the taste of the coffee beverage. At this time, the linkage sleeve 270 can be set with metal materials to further enhance the structural strength, or it can be, for example, rubber materials to achieve structural protection and thermal insulation.

[0064] A connecting rib may be provided between the first sleeve 271 and the second sleeve 272 of the linkage sleeve 270 to adapt the lateral spacing between the movable member 210 and the container assembly 100. The first sleeve 271, the second sleeve 272 and the connecting rib in the linkage sleeve 270 may be integrally formed, or may be separately formed and then connected in a detachable or non-detachable manner.

[0065] The linkage vertical rod 281 and the linkage horizontal rod 282 can also be integrally formed, or can be detachably or non-detachably connected after being separately formed. According to actual needs, a flow channel can be provided inside the linkage vertical rod 281 and the linkage horizontal rod 282, and the flow channel can pass through the lower piston member 120 and communicate with the channel 111. The flow channel can be used to connect external liquid to the channel 111 or discharge the liquid in the channel 111 to the outside according to actual needs.

[0066] Furthermore, in one embodiment, the brewing module further includes first stop protrusions 291 respectively disposed at the upper and lower ends of the first sleeve 271, and the first stop protrusions 291 limit the first sleeve 271 from moving up and down relative to the movable member 210. By disposing the first stop rib, when the movable member 210 links the lower piston member 120 to move up and down, the synchronous movement of the brewing container 110 can be limited, so that the lower piston member 120 can move up and down in the channel 111.

[0067] It should be noted that the arrangement of the two first stop protrusions 291 is not limited. The two first stop protrusions 291 are fixed roughly relative to the guide member 220, that is, fixed relative to the base 300. The first stop protrusion 291 can be integrally formed with the guide member 220, or the first stop protrusion 291 and the guide member 220 can be separately formed and then connected detachably or non-detachably. Figure 4 As shown, the two first stop protrusions 291 may be a fixed annular structure fixedly sleeved on the outer circumference of the guide member 220 .

[0068] And / or in one embodiment, the brewing module further includes second stop protrusions 292 respectively provided on both lateral sides of the second sleeve 272, and the second stop protrusions 292 limit the movement of the second sleeve 272 between the powder receiving position 310 and the brewing position 320. It can be understood that when there is no second stop protrusion 292, the container assembly 100 can be driven by the movable member 210 to perform a full circumference around the movable member 210. However, a full circumference travel is generally not required between the powder receiving position 310 and the brewing position 320, so by providing two second stop protrusions 292, the full circumference of the container assembly 100 can be effectively limited between the required powder receiving position 310 and the brewing position 320.

[0069] Please combine the specific Figures 4 to 7 In one embodiment, the driving device 200 also includes a driver 230 and a transmission member 240, the transmission member 240 is provided with a threaded hole 241 in the vertical direction, the movable member 210 is a rod extending in the vertical direction and is threadedly connected to the threaded hole 241, the driver 230 has an output shaft 231 extending in the vertical direction, the driver 230 is connected to the movable member 210 or the transmission member 240, so that the movable member 210 can be translated in the vertical direction and can be rotated along the vertical axis.

[0070] The driver 230 is, for example, a motor, and the output shaft 231 of the motor can be directly extended and arranged in the vertical direction, or can be extended and arranged in any direction of the horizontal plane. Taking the output shaft 231 extending and arranged in the vertical direction as an example, the output shaft 231 rotates axially in the vertical direction. When the output shaft 231 is connected to the transmission member 240, the transmission member 240 can be driven to rotate synchronously axially in the vertical direction. The movable member 210 is roughly rod-shaped, including a threaded rod segment and a guide rod segment connected in sequence. The threaded rod segment is provided with an external thread that is adapted to the threaded hole 241, and when the transmission member 240 is driven to rotate, the threaded rod is driven to rotate around the vertical axis and translate in the vertical direction.

[0071] The specific form of the transmission member 240 is not limited, and the driver 230 can be directly connected to the transmission member 240, or indirectly connected to the transmission member 240 based on the desired purpose. Figures 4 to 5 Taking the structure shown as an example, the output shaft 231 of the driver 230 is not coaxial with the movable member 210, that is, the output shaft 231 is offset to one side of the movable member 210. In this case, the driving device 200 may further include a driving gear 250 and a belt 260, the transmission member 240 is configured as a passive gear, the driving gear 250 is coaxially mounted with the output shaft 231, the belt 260 is provided with inner gear teeth, the belt 260 is wound around the outer periphery of the driving gear 250 and the transmission member 240, and meshes with the gear teeth of the driving gear 250 and the transmission member 240 respectively.

[0072] In view of the above, the design of the guide groove 211 and the guide protrusion 221 is as follows: Figures 4 to 7 The guide groove 211 shown is provided on the movable member 210, and the guide protrusion 221 is provided on the guide member 220 for explanation, wherein the two transverse groove sections are respectively the first transverse groove section 211b located at the upper end of the vertical groove section 211c, and the second transverse groove section 211d located at the lower end of the vertical groove section 211c. The first transverse groove section 211b has a first end D1 close to the vertical groove section 211c, and a second end D2 away from the vertical groove section 211c; the second transverse groove section 211d has a first end D3 close to the vertical groove section 211c, and a second end D4 away from the vertical groove section 211c:

[0073] It should be noted that the guide groove 211 also includes an entry groove section 211a. It can be understood that, taking the guide groove 211 being arranged on the outer peripheral side wall of the movable member 210 as an example: the movable member 210 includes a threaded rod section and a guide rod section connected in sequence from top to bottom. The guide groove 211 is arranged at the guide rod section. The outer diameter of the guide rod section is larger than the outer diameter of the threaded rod section, so that a step surface is formed at the connection between the guide rod section and the threaded rod section. The entry groove section 211a penetrates downward from the step surface to the second end D2 connected to the first transverse groove section 211b, so that the guide protrusion 221 can slide into the entry groove section 211a from top to bottom, and is directly located at the second end D2 of the first transverse groove section 211b.

[0074] It can be understood that the first transverse slot section 211b and the second transverse slot section 211d can be arranged on opposite sides of the vertical slot section 211c in the transverse direction. At this time, the driver 230 drives the movable member 210 to rotate in the same direction, so that the guide protrusion 221 can be guided along the second end D2 of the first transverse slot section 211b, the first end D1 of the first transverse slot section 211b, the vertical slot section 211c, the first end D3 of the second transverse slot section 211d, and finally to the second end D4 of the second transverse slot section 211d. However, since the second end D2 of the first transverse groove segment 211b and the second end D4 of the second transverse groove segment 211d both correspond to the container assembly 100 moving to the same powder receiving position 310, in order to make the second end D2 of the first transverse groove segment 211b and the second end D4 of the second transverse groove segment 211d be located at the same position in the vertical direction of the movable part 210, the first transverse groove segment 211b and the second transverse groove segment 211d need to jointly enclose the entire circumference of the movable part 210, and the spacing distance between the powder receiving position 310 and the brewing position 320 needs to be extended, which is not conducive to the compactness of the overall structure.

[0075] Therefore, in one embodiment, the two transverse groove sections are located on the same side of the vertical groove section 211c in the transverse direction. In this way, even if the second end D2 of the first transverse groove section 211b and the second end D4 of the second transverse groove section 211d are located at the same position in the vertical direction of the movable member 210, since the projections of the first transverse groove section 211b and the second transverse groove section 211d in the vertical direction overlap, the two do not need to occupy the entire circumference of the movable member 210, and the spacing distance between the powder receiving position 310 and the brewing position 320 can be arbitrarily designed according to actual needs.

[0076] Based on this, in one embodiment, the direction of the output shaft 231 can be switched, so that when the output shaft 231 rotates in one direction, the guide protrusion 221 is driven to move from the second end D2 of the first transverse groove section 211b to its first end D1; and when the output shaft 231 rotates in another direction, the guide protrusion 221 is driven to move from the first end D3 of the second transverse groove section 211d to its second end D4. In this way, it is helpful to match the structural design of the first transverse groove section 211b and the second transverse groove section 211d, and realize the reciprocating movement switching of the container assembly 100 between the powder receiving position 310 and the brewing position 320.

[0077] Furthermore, in one embodiment, the transverse groove section extends from the first end to the second end thereof gradually axially away from the vertical groove section 211c. In this way, the inclined setting helps to decompose the speed between the guide protrusion 221 and the transverse groove section in the transverse direction to a certain extent, so that when the container assembly 100 is switched between the powder receiving position 310 and the brewing position 320, the speed can be appropriately slowed down, making the rotation process of the container assembly 100 more stable.

[0078] When the output shaft 231 is switched in direction as described above, the inclined setting also helps to drive the lower piston member 120 to move downward appropriately when the guide protrusion 221 moves along the second end D2 of the first transverse groove section 211b to the first end D1, that is, when the container assembly 100 moves from the powder receiving position 310 to the brewing position 320, so as to avoid the powder received in the brewing container 110 from overflowing; and helps to drive the lower piston member 120 to move downward appropriately when the guide protrusion 221 moves along the first end D3 of the second transverse groove section 211d to the second end D4, that is, when the container assembly 100 moves from the brewing position 320 to the brewing and receiving powder position 310, so as to reserve sufficient space in the channel 111 for receiving coffee powder next time.

[0079] Furthermore, in one embodiment, the vertical slot section 211c extends longer in the vertical direction than the horizontal slot section. The vertical slot section 211c forms a longer vertical length, so that the lower piston member 120 can reciprocate within the channel 111 with a sufficient stroke, especially when the lower piston member 120 is required to move from bottom to top to perform an upper residue discharge operation, the coffee residue remaining in the channel 111 can be scraped out as much and as comprehensively as possible. The horizontal slot section forms a shorter vertical length, so that when the container assembly 100 is switched between the powder receiving position 310 and the brewing position 320, the lower piston member 120 only needs to move downward appropriately, so as to avoid excessive downward movement, which may cause the lower piston member 120 to escape from the channel 111.

[0080] Of course, the groove width of the guide groove 211 is adapted to the size of the guide protrusion 221 in the corresponding direction, which helps to limit the lateral displacement of the guide protrusion 221 by the groove width of the guide groove 211, thereby ensuring that the movement process of the container assembly 100 is more stable. The guide protrusion 221 can be directly slidably connected to the side groove wall of the guide groove 211, or the guide protrusion 221 can be a roller, which is rollingly connected to the side wall of the guide groove 211.

[0081] In one embodiment, the first end D1 / D3 is recessed with an arc-shaped limiting groove 211e in the horizontal direction; and / or the second end D2 / D4 is recessed with an arc-shaped limiting groove 211e in the vertical direction. In this way, the limiting groove 211e can limit the movement of the guide protrusion 221 that moves to this point to a certain extent, so as to prevent the guide protrusion 221 from easily moving in the reverse direction when the driver 230 does not apply a driving force, causing the container assembly 100 to return. The arc-shaped limiting groove 211e can appropriately reduce the limiting strength of the limiting groove 211e on the guide protrusion 221 when the driver 230 applies a driving force, so that the guide protrusion 221 can be moved out of the limiting groove 211e.

[0082] Specifically, please combine Figure 7 , driven by the driver 230 and the movable member 210, the guide protrusion 221 and the guide groove 211 have relative displacement, and form the following circulation path:

[0083] First see Figure 7The dotted line in the figure indicates that the guide protrusion 221 moves from the entry groove section 211a to the second end D2 of the first transverse groove section 211b, and the container assembly 100 is currently in the powder receiving position 310 for the first time; when the driver 230 rotates forward, the guide protrusion 221 moves from the second end D2 of the first transverse groove section 211b to the first end D1 of the first transverse groove section 211b, and drives the container assembly 100 to move from the powder receiving position 310 to the brewing position 320 for the first time. At the brewing position 320, the driver 230 switches forward and reverse, and the guide protrusion 221 reciprocates up and down along the vertical groove section 211c, and its up and down reciprocating stroke includes a powder shaking stroke, a pressing stroke, and a residue scraping stroke. When performing the powder shaking stroke, the up and down movement of the guide protrusion 221 can drive the lower piston member 120 to move up and down to achieve the purpose of shaking the powder, and can shake the powder received by the lower piston member 120 from the cone shape, which is convenient for the subsequent powder pressing operation. When performing the powder pressing stroke, the upper piston member 410 can be used to press the powder. When performing the residue scraping stroke, the coffee residue in the channel 111 can be scraped off. The residue scraping stroke is generally a bottom-up motion, which facilitates the discharge of the coffee residue upward out of the channel 111. Therefore, when the residue scraping stroke is completed, the driver 230 rotates forward, driving the guide protrusion 221 to move downward to the first end D3 of the second transverse groove section 211d. Then, the driver 230 reverses, driving the guide protrusion 221 to move from the first end D3 of the second transverse groove section 211d to the second end D4 of the second transverse groove section 211d, and is in the powder receiving position 310 for the second time.

[0084] Then see Figure 7 The solid line in the figure indicates that the guide protrusion 221 moves from the second end D4 of the second transverse groove section 211d to the first end D3 of the second transverse groove section 211d, driving the container assembly 100 to move to the powder receiving position 310 for the second time. Then, at the brewing position 320, referring to the above, a powder shaking stroke, a pressing stroke and a residue scraping stroke may be performed. Finally, the guide protrusion 221 moves from the first end D1 of the first transverse groove section 211b to the second end D2 of the first transverse groove section 211b, resets to the powder receiving position 310, and finally completes a whole circulation path. In a single circulation path, the container assembly 100 is driven to reciprocate twice between the brewing position 320 and the powder receiving position 310, which helps to make full use of the structure of the guide protrusion 221 and the guide groove 211, and realizes a smoother and simpler efficient activity switching of the container assembly 100 between the powder receiving position 310 and the brewing position 320.

[0085] Based on any of the above embodiments, at least two guide grooves 211 are arranged in parallel along the circumferential interval of the movable member 210; at least two guide protrusions 221 are arranged for the guide grooves 211. The arrangement of multiple groups of guide grooves 211 and guide protrusions 221 helps to increase the guiding stability between the guide protrusions 221 and the guide grooves 211, thereby ultimately ensuring the smooth movement of the container assembly 100.

All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
