[0002] Machines for preparing beverages, particularly coffee or tea, are known in the art, which include a brewing device comprising a brewing chamber with an opening through which the material to be brewed can be introduced and discharged.

[0003] Taking coffee machines as an example, the brewing unit, as the core mechanism of coffee brewing, generally has a very complex internal structure; moreover, this structure plays a decisive role in the taste of the brewed coffee. For the sake of structural simplicity, existing coffee machines typically integrate the brewing unit with the main frame. In these designs, because the brewing unit is fixed inside the machine, users cannot remove and clean the core component separately. Over time, the failure to promptly remove residual coffee or coffee grounds can cause internal pipe blockages, directly affecting the final taste of the coffee. Furthermore, because users cannot effectively clean the inside of the brewing unit, residual coffee grounds can mold, affecting not only the taste of the coffee but also contaminating the brewing chamber.

[0004] In related technologies, disassembling the brewing unit using other methods is quite complex. Users of coffee machines are prone to errors when installing and removing the brewing unit, or may be unable to disassemble it themselves, leading to malfunctions. These complex installation mechanisms typically require trained professionals for accurate operation, resulting in additional costs and making them uneconomical.

[0005] In addition, there are various pipe connections between the brewing device and the main support of the coffee machine. If the installation structure of the brewing device is not precise enough, the pipes may not align, which may cause problems such as failure to drive or leakage during use, thus affecting the customer's user experience.

[0035] The repeated use of the accompanying drawings in this specification and in the drawings is intended to represent the same or similar features or elements of this application. Detailed Implementation

[0036] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0037] It should be understood that terms such as “above,” “over,” “below,” and “under,” used herein to indicate spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another, as shown in the accompanying drawings. The terms “first,” “second,” and “third,” as used herein, are interchangeable to distinguish one component from another, and these terms are not intended to indicate the location or importance of individual components.

[0038] This utility model relates to a beverage machine 100, which can brew beverages such as coffee, tea or other beverages.

[0039] Reference Figures 1 to 7 As shown, the beverage machine 100 includes a body 20, a brewing assembly 30, and an upper piston assembly 40. The body 20 defines a receiving space 21 for installing and accommodating the brewing assembly 30. The brewing assembly 30 includes a brewing cylinder 32, a lower piston 33, and a support base 31. The lower piston 33 is movably connected to the brewing cylinder 32 to move up and down within the brewing cylinder 32, thereby ejecting the raw material residue from the brewing cylinder 32 during beverage preparation. The brewing cylinder 32 is mounted on the support base 31, which serves as the basic structure for supporting and positioning the brewing cylinder 32 and the lower piston 33. When the support base 31 is installed in the receiving space 21, a residue collection box 22 is provided on one side of the brewing assembly 30 to collect the raw material residue ejected from the brewing cylinder 32. A water receiving tray 23 is provided below the brewing assembly 30 to receive liquid or powder residue dripping from the brewing assembly 30 or the upper piston assembly 40.

[0040] The upper piston assembly 40 includes a mounting base 41 and an upper piston 43 disposed on the mounting base 41. The mounting base 41 is fixedly connected to the machine body 20, such as by screws. The upper piston 43 can engage with the brewing cylinder 32 from above, and the upper piston 43 and the lower piston 33 work together to compress and extract the beverage ingredients.

[0041] To improve the convenience of daily maintenance and cleaning, the support base 31 is detachably mounted in the receiving space 21. The user can install the brewing component 30 into or remove it from the receiving space 21 along a first direction, where the first direction is the direction of movement of the brewing component 30 relative to the machine body 20 during installation or removal. Figure 2 The direction indicated by the middle arrow is usually horizontal, which effectively simplifies the disassembly and assembly steps and improves the intuitiveness and efficiency of the operation.

[0042] To prevent the brewing component 30 from loosening or accidentally falling off during operation or transportation, a locking structure 35 is provided between the support base 31 and the body 20. The locking structure 35 includes a locking element 351 and an unlocking element 352. The user can unlock the device by operating the unlocking element 352, which facilitates the smooth disassembly of the brewing component 30 and improves safety and convenience.

[0043] The support base 31 includes a brewing end 314 and an outer portion 311. The brewing end 314 engages with the mounting base 41. A locking member 351 extends from the brewing end 314 to lock with the mounting base 41 along a first direction, achieving mechanical locking. That is, when the brewing component 30 is installed into the receiving space 21 of the body 20, the locking member 351 inserts into or engages with the corresponding position of the mounting base 41, ensuring that the brewing component 30 will not loosen or fall off during brewing or transportation. The outer portion 311 is positioned opposite to the receiving space 21 along the first direction. The outer portion 311 is provided with a latching position 312 for finger gripping. An unlocking member 352 is located on one side of the latching position 312, facilitating single-handed gripping and operation of the unlocking member 352, further optimizing the user's holding experience.

[0044] The aforementioned structure enables the entire brewing component 30 to be detachable, facilitating regular cleaning and maintenance by the user and effectively improving the hygiene and ease of use of the equipment. Furthermore, the locking element 351 extends from the brewing end 314 to lock with the mounting base 41 in the first direction. While locking the brewing component 30, it also positions the brewing component 30 and the upper piston assembly 40. This comprehensive locking and positioning mechanism ensures accurate positioning of the brewing component 30 during assembly or disassembly, preventing misoperation and enhancing the safety and reliability of the beverage machine 100, thus meeting the user's needs for efficient, convenient, and easy-to-clean beverage equipment.

[0045] The holding position 312 is a structural part on the outer side 311 of the support base 31 specifically designed for finger gripping and force application, making it easy for users to insert their fingers to grip and apply force when loading and unloading the brewing component 30.

[0046] In one embodiment, the outer portion 311 is provided with a protrusion 313, and the unlocking member 352 and the fastening position 312 are respectively provided on both sides of the protrusion 313; a connecting rod 353 is provided between the unlocking member 352 and the locking member 351, and the unlocking member 352 moves toward the fastening position 312 to at least partially embed itself in the protrusion 313, and the connecting rod 353 drives the locking member 351 as the unlocking member 352 moves.

[0047] The clamping position 312, through optimized structural design, uses a protrusion 313 set on the surface of the outer part 311 as the force point for gripping, which effectively improves the user's operating comfort and anti-slip properties, reduces the risk of misoperation, and meets the requirements of ergonomics.

[0048] Reference Figure 8The support base 31 includes a cover component 301, which is fixedly connected to the outer side portion 311. The protrusion 313 can be defined by the cover component 301. To enhance the automatic reset capability of the locking structure 35, the locking structure 35 also includes an elastic element, which is disposed on the inner side of the cover component 301. The elastic element presses against the unlocking member 352 in a direction away from the latching position 312. When the unlocking member 352 is released, the elastic element can automatically push the unlocking member 352 and then drive the connecting rod 353 to reset, restoring the locked state and ensuring that the assembled brewing assembly 30 is always in a safe and reliable locked state.

[0049] The rational design of the brewing component 30 not only ensures efficient collaboration between parts, but also allows the entire component to be disassembled for cleaning or maintenance, further improving the hygiene and ease of maintenance of the beverage machine 100, and addressing the problems of inconvenient cleaning and inaccurate positioning in traditional beverage machine 100 structures. The lid component 301, as an independent component defining the protrusion 313, makes it easier to ensure the dimensions of the protrusion 313, and also facilitates the installation of the elastic element and the unlocking element 352.

[0050] In one embodiment, the outer portion 311 is provided with a first recess 315 and a second recess 316. The first recess 315 is adjacent to the unlocking member 352, and the second recess 316 is located on one side of the cover member 301. The fastening position 312 is defined by the side of the cover member 301 and the second recess 316.

[0051] The cover component 301 is gripped in conjunction with the recessed portion. When the user operates it, pressing the unlocking member 352 with the thumb provides space for the thumb to enter, while the other fingers can hold the side of the cover component 301. The second recessed portion 316 provides space to unlock the locking member 351 and remove the brewing component 30 from the receiving space 21.

[0052] Reference Figure 4 As shown, one end of the connecting rod 353 is pivotally connected to the locking member 351, and the other end of the connecting rod 353 is pivotally connected to the unlocking member 352; the unlocking direction of the unlocking member 352 and the locking direction of the locking member 351 form an obtuse angle α. The setting of the relative angle between the unlocking direction of the unlocking member 352 and the locking direction of the locking member 351 makes the unlocking operation more convenient and effortless.

[0053] The unlocking component 352 and the locking component 351 are pivotally connected at a specific angle by a connecting rod 353. When the unlocking component 352 moves toward the holding position 312, the connecting rod 353 will drive the locking component 351 to move synchronously, thereby achieving integrated unlocking, which is labor-saving and has high structural reliability.

[0054] To further ensure the precise assembly and smooth disassembly of the brewing component 30 within the body 20, a limiting and guiding structure is provided between the support base 31 and the body 20.

[0055] Reference Figures 9 to 11 The brewing end 314 is provided with a retaining rib 317, which protrudes into the receiving space 21 along the first direction. The mounting base 41 is provided with a retaining groove 411 and a limiting groove 413. The retaining rib 317 and the locking member 351 can respectively be inserted and engaged with the retaining groove 411 and the limiting groove 413 on the mounting base 41.

[0056] The limiting groove 413 is located on the bottom surface of the mounting base 41 facing the brewing end 314, and is used to receive the locking member 351 when the brewing component 30 is installed, thus limiting and positioning it. The slot 411 is located on the front surface of the mounting base 41 facing away from the receiving space 21, and is used to cooperate with the retaining rib 317 to further limit the relative position of the support base 31 and the mounting base 41 during installation, preventing the brewing component 30 from shifting or detaching when subjected to force during use, thereby ensuring the safety and stability of the overall assembly. The retaining rib 317 and the locking member 351 limit the connection between the support base 31 and the mounting base 41 from different directions, ensuring that the connection between the support base 31 and the mounting base 41 is reliable when the beverage machine 100 is in use.

[0057] A first guide structure and a second guide structure may also be provided between the support base 31 and the body 20. These two guide structures extend along the first direction respectively. The first guide structure is located at the connection between the support base 31 and the mounting base 41, while the second guide structure is diagonally arranged relative to the geometric center of the outer side and the first guide structure.

[0058] Through the synergistic effect of the aforementioned limiting and guiding structures, the brewing component 30 can be smoothly guided into the correct position when installed into the machine body 20, achieving stable docking and precise positioning. Simultaneously, it can smoothly guide the component out during disassembly, avoiding jamming or damage due to improper operation. This structural design not only improves the mechanical fit precision between the brewing component 30 and the machine body 20, but also greatly enhances the convenience of loading and unloading and the reliability of the equipment, ensuring efficient and safe daily maintenance and cleaning of the beverage machine 100.

[0059] In one specific embodiment, the first guiding structure includes guide grooves and / or guide rails respectively disposed on the brewing end 314 and the support base 31. Specifically, the brewing end 314 is provided with a first guide groove 302 and / or a first guide rail 304, and the support base 31 is provided with a second guide groove 414 and / or a second guide rail 412. The first guide groove 302 cooperates with the second guide rail 412, and the first guide rail 304 cooperates with the second guide groove 414. In this embodiment, the brewing end 314 is provided with both the first guide groove 302 and the first guide rail 304, and the support base 31 is provided with both the second guide groove 414 and the second guide rail 412. The guide grooves and guide rails form a stepped guiding structure, ensuring the fitting accuracy between the support base 31 and the mounting base 41, and improving the reliability of the beverage machine 100.

[0060] Reference Figure 2 and Figure 10 The second guiding structure includes a third guide groove 213 and a third guide rail 303 respectively disposed on the body 20 and the support base 31. The cross-section of the third guide rail 303 and the cross-section of the third guide groove 213 are respectively constructed as L-shaped. During the installation and disassembly of the brewing component 30 relative to the body 20 along the first direction, the third guide groove 213 and the third guide rail 303 cooperate to guide along the first direction while achieving limiting along the perpendicular to the first direction.

[0061] The innovative design of the above structure allows the brewing component 30 to be quickly installed or removed, and to remain firmly positioned during operation, significantly improving the safety, ease of use, and user experience of the beverage machine 100, and overcoming the problems of cumbersome installation and removal, easy loosening, or difficulty in positioning of existing beverage machines 100.

[0062] Reference Figure 2 as well as Figure 6 and Figure 7 In one embodiment, the brewing cylinder 32 can selectively move between two positions relative to the support base 31, enabling it to be coaxial with or misaligned with the upper piston 43. When the brewing cylinder 32 is coaxial with the upper piston 43, powder pressing and beverage brewing can be achieved. When the brewing cylinder 32 moves toward misalignment with the upper piston 43, the slag discharge of the brewing cylinder 32 and the receiving of raw materials for the preparation of the next beverage can be achieved.

[0063] To prevent the brewing cylinder 32 from unexpectedly rotating or moving relative to the support base 31 after the brewing assembly 30 is removed from the body 20, a self-locking mechanism 36 is provided on the support base 31, and a release part 26 is provided in the receiving space 21 of the body 20. The release part 26 is connected to the self-locking mechanism 36 to allow the brewing cylinder 32 to move relative to the support base 31; when the brewing assembly 30 is removed from the receiving space 21, the release part 26 separates from the self-locking mechanism 36, and the self-locking mechanism 36 restricts the movement of the brewing cylinder 32 relative to the support base 31.

[0064] Specifically, when the brewing assembly 30 is assembled into the body 20, the release part 26 cooperates with the self-locking mechanism 36 to allow the brewing cylinder 32 to rotate or move relative to the support base 31 as necessary, achieving accurate docking between the brewing cylinder 32 and the upper piston 43. After the brewing assembly 30 is removed from the receiving space 21, the release part 26 separates from the self-locking mechanism 36. At this time, the self-locking mechanism 36 automatically restricts the movement of the brewing cylinder 32 relative to the support base 31, keeping the brewing cylinder 32 in a vertical powder-receiving state, preventing the brewing cylinder 32 from being misaligned or rotated due to accidental shaking during disassembly and cleaning, thus ensuring accurate subsequent installation and smooth cooperation with the body 20.

[0065] Reference Figures 5 to 7 The support base 31 has a receiving cavity 306 for the movement of the brewing cylinder 32. The self-locking mechanism 36 may include a locking rod 361 and a second elastic member 362. The locking rod 361 and the second elastic member 362 are disposed in the receiving cavity 306 of the support base 31. The brewing cylinder 32 is provided with a locking block 321 for engagement. One end of the locking rod 361 is provided with a locking hook 363. The locking hook 363 is engaged with the locking block 321 to restrict the movement direction of the brewing cylinder 32. Specifically, it restricts the brewing cylinder 32 from moving relative to the brewing base toward a position coaxial with the upper piston 43. The second elastic member 362 presses against the locking rod 361 so that the locking hook 363 and the locking block 321 are always engaged.

[0066] Through the above structural design, the self-locking mechanism 36 can automatically lock after the brewing component 30 is removed, effectively preventing the brewing cylinder 32 from rotating or shifting by mistake, improving the maintenance convenience and safety of the equipment, solving the technical problems of easy loosening of the brewing cylinder 32 and difficulty in reassembly alignment during the disassembly and cleaning process of the existing beverage machine 100, and ensuring that the brewing component 30 can always cooperate with the machine body 20 in the correct position.

[0067] Reference Figure 11 In one embodiment, the brewing cylinder 32 is rotatable relative to the support base 31 between two positions to achieve coaxiality or misalignment with the upper piston 43. The brewing cylinder 32 has an opening 322, the edge 323 of which protrudes radially outward along the brewing cylinder 32 for positioning in conjunction with the relevant structure of the support base 31 during rotation. To further achieve precise positioning and support, the support base 31 includes a top plate 307 extending along the rotation path of the brewing cylinder 32. The top plate 307 has a relief groove 308, and the edge 323 of the opening 322 is supported on the edge of the relief groove 308.

[0068] When the brewing cylinder 32 rotates between the two positions, it is effectively limited and supported by the top plate 307, preventing undesirable rotation or movement of the brewing cylinder 32. Furthermore, during beverage brewing, the upper piston 43 extends into the brewing cylinder 32 to perform a pressing operation, requiring the brewing cylinder 32 to withstand significant downward pressure from the upper piston 43. The top plate 307 supports the edge 323 of the brewing cylinder 32, providing more reliable support and ensuring reliable engagement between the upper piston 43 and the brewing cylinder 32 throughout the brewing process.

[0069] In addition, the cavity wall of the receiving cavity 306 is provided with a guide groove 305, which can be an arc-shaped groove; the brewing cylinder 32 is provided with a guide post 325, which extends into the guide groove 305, and the guide groove 305 precisely guides the rotation of the brewing cylinder 32 between two positions. The guide groove 305 is located below the top plate 307. The guide groove 305 and the top plate 307 cooperate to more accurately limit the rotation path of the brewing cylinder 32, ensuring that the brewing process of the beverage machine 100 is more reliable.

[0070] Optionally, the brewing end 314 protrudes towards the mounting base 41, with a portion of the top plate 307 located inside the brewing end 314 and the other portion forming the outer surface of the support base 31. This design ensures the overall structural strength and provides stable support for the rotation and positioning of the brewing cylinder 32. Through mechanical cooperation, this design ensures that the brewing cylinder 32 remains in a reliable position during assembly, operation, and cleaning / maintenance. This not only facilitates user operation but also enhances the structural stability and service life of the equipment, further improving upon the shortcomings of traditional beverage machines 100 in terms of component rotation, limiting, and resetting.

[0071] Reference Figure 2 , Figure 6 , Figure 7 as well as Figure 9 In one embodiment, the body 20 is further provided with a drive mechanism, which includes a motor (not shown in the figure) and a drive shaft 28. The motor rotates to drive the drive shaft 28 to rotate. The support base 31 is provided with a transmission connection part 328, which is drivenly connected to the drive shaft 28.

[0072] A transmission structure is provided between the drive shaft 28 and the lower piston 33. This transmission structure is at least partially housed within the piston drive housing 331. The transmission structure includes a gear set 332 and a rack 333. The rack 333 meshes with both sides of the gear set 332, and the lower piston 33 is fixed relative to the rack 333. The motor drives the drive shaft 28 to rotate. The gear set 332 engages with the rack 333, causing the rack 333 to move the lower piston 33 up and down, thereby enabling the lower piston 33 to push out the raw material residue and return to its original position. When the rack 333 moves the lower piston 33 to its extreme position, the drive shaft 28 can drive the brewing cylinder 32 to rotate between a first position and a second position via the transmission structure.

[0073] The drive mechanism can rotate the brewing cylinder 32 between the first and second positions, enabling automatic powder dispensing and brewing, further improving the automation level and work efficiency of the beverage machine 100.

[0074] Reference Figures 12 to 13 In another embodiment of the beverage machine 100, the body 20 and the upper piston assembly 40 are the same as in the embodiment described above. A locking structure 35 is provided between the support base 31 and the body 20. The locking structure 35 includes a locking member 351 and an unlocking member 352. The brewing assembly 30 is installed into or removed from the receiving space 21 along a first direction. The support base 31 includes a brewing end 314 and an outer side 311. The brewing end 314 engages with the mounting base 41. The outer side 311 faces away from the receiving space 21 along the first direction. The outer side 311 is provided with a fastening position 312. The unlocking member 352 is provided on one side of the fastening position 312. The locking member 351 extends from the brewing end 314 to lock with the mounting base 41 along the first direction.

[0075] In this embodiment, the elements or components with the same reference numerals as those in the above embodiments have the same structure and function, and will not be described again here. Unlike the above embodiments, the support base 31 includes a first side surface 318 and a second side surface 319 respectively connecting the two sides of the outer side portion 311. The unlocking member 352 and the fastening position 312 are spaced apart from the first side surface 318 to the second side surface 319. The unlocking member 352 protrudes outward from the outer side portion 311, and the outer side portion 311 is provided with a raised rib 310 extending vertically. The outer side portion 311 is provided with a recess 309, which is located at the connection between the outer side portion 311 and the second side surface 319 and adjacent to the raised rib 310. The fastening position 312 is defined by one side of the raised rib 310 and the recess 309.

[0076] The protruding design of the unlocking member 352, combined with the recess 309, allows for easy gripping. When the user presses the unlocking member 352 with their thumb, the protruding unlocking member 352 provides a gripping position for the thumb. The remaining fingers can be held in the holding position 312 defined by the protruding rib 310 and the recess 309. The recess 309 is located at the connection between the outer side 311 and the second side 319. When the fingers are in the recess 309, it is easier to apply force and hold with the protruding rib 310, thereby facilitating the unlocking of the locking member 351 and the removal of the brewing component 30 from the receiving space 21.

[0077] In addition, in this embodiment, the top plate 307 is located inside the receiving cavity 306 of the support base 31, and the edge 323 of the opening 322 is supported on the top plate 307 and located between the outer surface of the support base 31 and the top plate 307. This can both support the edge 323 of the brewing cylinder 32 and confine the edge 323 of the brewing cylinder 32 inside the receiving cavity 306, making the brewing assembly 30 more compact overall.

[0078] In its overall structural design, the beverage machine 100 achieves high efficiency, safety, and convenience in assembly, disassembly, use, and cleaning processes through the detachable connection between the brewing component 30 and the machine body 20, combined with multiple limiting, locking, and self-locking mechanisms 36.

[0079] In daily use, users can smoothly insert or remove the brewing component 30 from the main body 20 along the first direction. The user can operate by squeezing the buckle 312, and with the linkage structure of the unlocking component 352 and the locking component 351, the locking and releasing of the locking component 351 can be easily completed without complicated tools. The locking rib 317, the limiting groove 413, and the guide structure work together to ensure precise positioning of the brewing component 30 and the main body 20, significantly reducing the risk of misalignment during assembly. The protrusion 313, the rib 310, and the concave design on the outer side 311 of the support base 31 further enhance the comfort and safety of holding the device, reflecting ergonomic optimization.

[0080] During maintenance and cleaning, users can easily disassemble the brewing assembly 30 by following the designed structure, allowing for thorough cleaning of components such as the brewing cylinder 32 and lower piston 33. The self-locking mechanism 36 automatically maintains the correct position of the brewing cylinder 32, preventing subsequent assembly difficulties due to unexpected rotation and improving the convenience and accuracy of maintenance. The rotation of the brewing cylinder 32, in conjunction with the clearance groove 308 structure of the top plate 307, makes the assembly more flexible in operation under different working conditions, while ensuring that it is in a mechanically limited and stable supporting position in both working and non-working states. The entire implementation process not only ensures the safety and sealing of the equipment but also greatly improves the user's operating experience and the ease of cleaning the equipment.

[0081] The above-described embodiments can also be structurally adjusted or optimized for the outer side 311, the cover component 301, the guide structure, and the self-locking mechanism 36 according to different actual needs, to achieve various variant solutions. For example, different sizes or shapes of the latching position 312, the rib 310, or the cover component 301 can be configured for different models, or different guide structures and self-locking structures can be used to adapt to more types of brewing cylinders 32 and the body 20, achieving wide application adaptability.

[0082] All the above structural solutions and technical measures can work together to achieve the convenience, accuracy and high safety of the overall assembly, positioning, operation, maintenance and cleaning of the beverage machine. The implementation of this utility model is not limited to the specific structure described above, and various reasonable modifications and substitutions can be made under the guidance of those skilled in the art, which should still fall within the protection scope of this utility model.

[0083] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0084] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
