Description

Technical Field

[0001] This application belongs to the field of coffee brewing technology, and in particular relates to a quick-release brewing component and beverage machine. Background Technology

[0002] Beverage machines are widely used in homes, offices, restaurants, cafes, and other settings to provide various types of beverages. Coffee machines, as a type of beverage machine, can brew different types of coffee. In current coffee machine technology, the brewing assembly (brewing head, filter holder, etc.) is one of the core components, its function being to achieve uniform extraction of coffee grounds. However, because coffee grounds, limescale, and other stains easily accumulate on the brewing assembly during use, it requires regular disassembly, cleaning, or replacement. Current coffee machine brewing assemblies are typically fixed using bolts, clips, or threaded connections, making disassembly cumbersome, requiring tools or multiple operations, resulting in a poor user experience. This is not only time-consuming and labor-intensive but can also lead to component damage or decreased sealing due to improper operation. While some high-end models have quick-release structures, the large number of parts results in high costs and a high failure rate. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide a quick-release brewing component and beverage machine with simple structure and convenient operation.

[0004] The technical solution adopted in this application embodiment is a quick-release brewing assembly for use in a beverage machine, the quick-release brewing assembly comprising: A fixed base is provided on the frame of the beverage machine. The fixed base is provided with a fastener and a base positioning hole or a base positioning pin. A brewing cup is provided with a cup positioning pin that mates with a seat positioning hole on the fixed base or a cup positioning hole that mates with a seat positioning pin on the fixed base, so that when the brewing cup is installed in the fixed base, the seat positioning pin is inserted into the cup positioning hole and the cup positioning pin is inserted into the seat positioning hole. A locking mechanism is provided on the brewing cup and includes a retractable buckle. When the brewing cup is installed in the fixing base, the buckle automatically springs into the buckle position of the fixing base to lock the brewing cup on the fixing base. Under the action of external force, the buckle can disengage from the buckle position to release the locking of the brewing cup and allow the brewing cup to be removed from the fixing base.

[0005] In an optional embodiment, the fixing base has an inner cavity for accommodating the brewing cup, and one side of the fixing base is open, forming an opening for the brewing cup to enter and exit the inner cavity; at least one positioning hole is provided on the cavity wall opposite to the opening; at least one cup positioning pin is provided on the outer wall of the brewing cup; when the brewing cup is installed in the inner cavity of the fixing base, the cup positioning pin is inserted into the positioning hole of the fixing base. By providing the positioning hole in the fixing base and the positioning pin in the brewing cup, it is convenient for the positioning pin to be directly inserted into the positioning hole when the brewing cup is installed in the fixing base.

[0006] In an optional embodiment, three positioning holes are provided on the cavity wall opposite to the opening. The three positioning holes are a first positioning hole, a second positioning hole, and a third positioning hole. The first and second positioning holes are both circular holes, and the line connecting their centers is a horizontal line. The third positioning hole is a T-shaped hole, and the vertical part of the third positioning hole is located on a vertical line perpendicular to the horizontal line. The height of the third positioning hole is lower than the height of the first and second positioning holes. The outer wall of the brewing cup is equipped with three cup positioning pins, namely a first cup positioning pin, a second cup positioning pin, and a third cup positioning pin. The first and second cup positioning pins are cylindrical and are respectively used to insert into the first and second positioning holes of the base. The third cup positioning pin is T-shaped and is used to insert into the third positioning hole of the base. In this way, the precise horizontal positioning of the brewing cup can be guaranteed, and the brewing cup can be inserted into the fixing base at the correct angle.

[0007] In an optional embodiment, positioning grooves are provided on the two side walls of the inner cavity adjacent to the opening, and one end of each positioning groove extends to the side of the cavity wall where it is located that is adjacent to the opening of the inner cavity. The outer wall of the brewing cup is provided with multiple positioning protrusions. When the brewing cup is installed in the inner cavity of the fixing base, the multiple positioning protrusions extend into the multiple positioning grooves one by one. This further restricts the displacement of the brewing cup and improves the stability of the brewing cup after installation.

[0008] In an optional embodiment, the locking mechanism further includes a lock housing and an elastic component. Both the latch and the elastic component are housed within the lock housing. The elastic component applies force to the latch, causing the latch head at one end of the latch to extend out of the lock housing and engage with the latch on the fixed base, thus locking the brewing cup onto the fixed base. When a force is applied to the latch to overcome the elastic component, the latch head can disengage from the latch, releasing the brewing cup from the lock. The locking mechanism has a simple and reasonable structure, is easy to operate, and can effectively lock and unlock the brewing cup.

[0009] In an optional embodiment, the fixing seat has an inner cavity for accommodating the brewing cup, one side of the fixing seat is open, forming an opening for the brewing cup to enter and exit the inner cavity, and the fixing seat is provided with the fasteners on the two cavity walls adjacent to the opening; The locking mechanism includes two latches, with their first sides facing each other and their latch heads located on their second sides, which are far apart from each other. The two ends of the elastic member abut against the first sides of the two latches, allowing the latch heads to extend from opposite sides of the lock housing and engage with the two latch positions on the fixing base. This creates a bidirectional locking force, and the clamping action of the latches against the outer wall of the brewing cup during locking ensures good stability of the brewing cup. In an optional embodiment, the lock housing has a through opening and a latching hole on opposite sides, and the latching head extends out of the lock housing through the latching hole; The second side of the buckle is also provided with a pressing part, which is exposed through the through-hole. When the pressing part is pressed, it pushes the two buckles to move towards each other, and the buckle heads of the two buckles disengage from their respective fastening positions. The elastic component compresses and accumulates elastic potential energy. By pressing the pressing part, the buckle heads can be disengaged from their fastening positions, completing the disassembly. The entire process requires no tools and can be completed in 1 second with one hand. In an optional embodiment, the top side of the buckle is provided with a limiting protrusion, and the inner top wall of the lock housing is provided with a stop portion. When the two buckles move in opposite directions under the action of the elastic component, the stop portion blocks the limiting protrusion, thus preventing the buckles from dislodging from the lock housing.

[0010] In an optional embodiment, each of the two buckles has a protruding post on its first side, and the outer peripheral surface of the protruding post has a protruding ridge and forms a spring seat; The elastic component is a spring, with both ends of the spring respectively sleeved on the outside of the protruding post.

[0011] A beverage machine includes a frame and a drive mechanism, and further includes a quick-release brewing assembly as described in any of the above embodiments. The quick-release brewing assembly has a fixed base mounted on the frame and can move along a track on the frame under the drive of the drive mechanism to switch between a powder-dispensing position and a brewing position. The brewing cup of the quick-release brewing assembly is detachably mounted on the fixed base and can move synchronously with the fixed base when installed. Because the beverage machine of this application has a quick-release brewing assembly, it allows for quick installation and removal of the brewing cup, improving operational convenience and facilitating the replacement or cleaning of the brewing cup.

[0012] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: This application, based on the pre-positioning guidance, the automatic locking engagement of the horizontal insertion triggering locking mechanism, and the coordinated work of radial pressing and fixing, realizes the quick assembly and disassembly of the brewing cup, which is especially suitable for beverage machines that require frequent rinsing or replacement of brewing cups. Furthermore, this application has a simple structure, is easy to operate, and can ensure long-term stability.

[0029] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] This application provides a quick-release brewing assembly for use in beverage machines, including but not limited to coffee machines. For ease of description, this application uses a coffee machine as an example.

[0031] like Figures 1 to 4 As shown, the quick-release brewing assembly of this application embodiment includes a fixed base 1, a brewing cup 2, and a locking mechanism 3. The fixed base 1 is mounted on the frame of the beverage machine and has a fastening position 11, as well as a seat positioning hole or a seat positioning pin. The brewing cup 2 has a cup positioning pin that mates with the seat positioning hole of the fixed base 1 or a cup positioning hole that mates with the seat positioning pin of the fixed base 1, so that when the brewing cup 2 is installed in the fixed base 1, the seat positioning pin is inserted into the cup positioning hole, and the cup positioning pin is inserted into the seat positioning hole. The locking mechanism 3 is mounted on the brewing cup 2 and includes a retractable buckle 31, so that when the brewing cup 2 is installed in the fixed base 1, the buckle 31 automatically springs into the fastening position 11 of the fixed base 1, locking the brewing cup 2 on the fixed base 1, and the buckle 31 can be disengaged from the fastening position 11 under external force to release the lock on the brewing cup 2, allowing the brewing cup 2 to be removed from the fixed base 1.

[0032] In this embodiment of the quick-release brewing assembly, the brewing cup 2 and the fixed base 1 are positioned by the cooperation of the positioning pin and the positioning hole. The brewing cup 2 is also locked or unlocked to the fixed base 1 by the locking mechanism 3, so that the brewing cup 2 can be fixed on the fixed base 1 for operations such as receiving powder, pressing powder and brewing, and can also be removed from the fixed base 1 for replacement or rinsing. The structure is simple, stable and reliable, and easy and quick to assemble and disassemble, making it especially suitable for coffee machines that require frequent rinsing or replacement of the brewing cup 2.

[0033] In some embodiments, the fixing base 1 has an inner cavity for accommodating the brewing cup 2, and one side of the fixing base 1 is open, forming an opening for the brewing cup 2 to enter and exit the inner cavity, i.e. Figure 6 The side facing the user is open. At least one seat positioning hole is provided on the cavity wall opposite the opening; at least one cup positioning pin is provided on the outer wall of the brewing cup 2. When the brewing cup 2 is installed in the inner cavity of the fixed base 1, the cup positioning pin is inserted into the seat positioning hole. By providing a hole in the fixed base 1 and placing the pin on the brewing cup 2, it is easy for the pin to be inserted into the hole when the brewing cup 2 is inserted into the fixed base 1 during assembly.

[0034] The number of positioning holes in the base is unlimited and can be selected according to actual needs, but the stability and reliability of positioning must be guaranteed. The number of cup positioning pins is the same as the number of positioning holes in the base, and they correspond one-to-one.

[0035] For example, such as Figure 6As shown, three positioning holes are provided on the cavity wall opposite the opening: a first positioning hole 12, a second positioning hole 13, and a third positioning hole 14. The first and second positioning holes 12 and 13 are both circular holes, and the line connecting their centers is horizontal. The third positioning hole 14 is a T-shaped hole, with its vertical portion located on a vertical line perpendicular to the horizontal line, and its height is lower than that of the first and second positioning holes 12 and 13. Figure 7 As shown, the outer wall of the brewing cup 2 is provided with three cup positioning pins, namely the first cup positioning pin 21, the second cup positioning pin 22, and the third cup positioning pin 23. The first cup positioning pin 21 and the second cup positioning pin 22 are both cylindrical and are used to insert into the first positioning hole 12 and the second positioning hole 13 respectively. The third cup positioning pin 23 is T-shaped and is used to insert into the third positioning hole 14. By the cooperation of the two cylindrical first cup positioning pins 21 and the second cup positioning pin 22 with the two circular first positioning holes 12 and the second positioning holes 13, the brewing cup 2 can be accurately positioned horizontally. By the cooperation of the T-shaped third cup positioning pin 23 with the T-shaped third positioning hole 14, it is ensured that the brewing cup 2 is inserted into the fixing base 1 at the correct angle, thus preventing mistaken insertion.

[0036] In some embodiments, such as Figure 6 As shown, positioning grooves 15 are respectively provided on the two sides of the cavity wall adjacent to the opening. One end of the positioning groove 15 extends to the side of the cavity wall where it is located that is adjacent to the opening of the cavity. Figure 7 As shown, the outer wall of the brewing cup 2 is provided with multiple positioning protrusions 24. When the brewing cup 2 is installed in the inner cavity of the fixing base 1, the multiple positioning protrusions 24 extend into the multiple positioning grooves 15 one by one. By providing positioning grooves 15 on the opposite side cavity walls of the fixing base 1, and providing positioning protrusions 24 on the outer wall of the brewing cup 2 that cooperate with the positioning grooves 15, the displacement of the brewing cup 2 is further restricted, and the stability of the brewing cup 2 after installation is improved.

[0037] Optional, such as Figure 6 As shown, a positioning groove 15 is provided on each of the two side walls of the inner cavity, and the two positioning grooves 15 on the two side walls correspond to each other and are located on the upper part of the cavity wall; correspondingly, two positioning protrusions 24 are provided on the upper part of the outer wall of the brewing cup 2. Continuing with the combination... Figure 6The first positioning hole 12 and the second positioning hole 13 are both located on the lower part of the cavity wall opposite to the opening, and the third positioning hole 14 is located near the bottom of the cavity wall opposite to the opening. Correspondingly, the first cup positioning pin 21 and the second cup positioning pin 22 are located on the lower part of the outer wall of the brewing cup 2, and the third cup positioning pin 23 is located near the bottom of the outer wall of the brewing cup 2. In this way, the brewing cup 2 can be positioned from top to bottom, ensuring the stability of the brewing cup 2 after installation.

[0038] In some embodiments, such as Figure 8 As shown, the locking mechanism 3 also includes a lock housing 32 and an elastic component 33. Both the latch 31 and the elastic component 33 are located within the lock housing 32. The elastic component 33 applies force to the latch 31, causing the latch head 311 at one end of the latch 31 to extend out of the lock housing 32 and engage with the latch position 11 on the fixing base 1, thus locking the brewing cup 2 onto the fixing base 1. When a force is applied to the latch 31 to overcome the elastic component 33, the latch head 311 can disengage from the latch position 11, releasing the lock on the brewing cup 2. The locking mechanism 3 has a simple and reasonable structure, is easy to operate, and can effectively lock and unlock the brewing cup 2, ensuring the stability of the brewing cup 2 after installation and enabling quick disassembly.

[0039] In some embodiments, the fixing base 1 has latches 11 on the two side walls adjacent to the opening. The locking mechanism 3 includes two latches 31, with their first sides facing each other and their latch heads 311 respectively located on their second sides away from each other. The two ends of the elastic member 33 abut against the first sides of the two latches 31, so that the latch heads 311 of the two latches 31 can extend from the opposite sides of the locking housing 32 and respectively engage with the two latches 11 on the fixing base 1. By providing two latches 11 and two latches 31, a symmetrical bidirectional locking can be formed, improving the reliability of the locking and ensuring that the brewing cup 2 will not detach from the fixing base 1.

[0040] like Figure 9 As shown, the lock housing 32 has a through opening 321 and a latching hole 322 on opposite sides, and the latching head 311 extends out of the lock housing 32 through the latching hole 322. Figure 10 As shown, a pressing part 312 is also provided on the second side of the buckle 31. The pressing part 312 is exposed through the through-hole 321. See Figure 8 When both pressing parts 312 are pressed simultaneously, the two latches 31 are pushed to move towards each other. The two latches 31 cause the latch heads 311 to disengage from their respective latch positions 11, releasing the lock on the brewing cup 2. At this time, both latches 31 are in the unlocked state. (See below) Figure 3Simultaneously, the elastic component 33 compresses and accumulates elastic potential energy. When the pressing force applied to the two pressing parts 312 is removed, the two latches 31, under the action of the elastic component 33, drive the latch heads 311 to move in opposite directions and reset. At this time, if the brewing cup 2 is located inside the fixed base 1, the latch heads 311 of the two latches 31 can respectively extend into the two latch positions 11 of the fixed base 1. See [link / reference]. Figure 4 and Figure 5 The latch 31 is in the locked state, locking the brewing cup 2. That is, the two latches 31 have locked and unlocked states respectively, and can switch between the locked and unlocked states respectively, thereby realizing the locking and unlocking of the brewing cup 2.

[0041] In some embodiments, such as Figure 10 As shown, the top side of the latch 31 is provided with a limiting protrusion 313, and the inner top wall of the lock housing 32 is provided with a stop (not shown in the figure). When the two latches 31 move in opposite directions under the action of the elastic member 33, the stop blocks the limiting protrusion 313, preventing the latches 31 from disengaging from the lock housing 32. By providing the limiting protrusion 313, the latches 31 can be prevented from detaching from the lock housing 32 under the action of the elastic member 33, keeping the latches 31 inside the lock housing 32, resulting in a stable and reliable structure.

[0042] The locking housing 32 is fixed to the outer wall of the fixing base 1, which is exposed outside the opening of the fixing base 1, by means of screws or other connecting parts. The latch 31 is exposed on the side of the locking housing 32 facing the brewing cup 2, so that when the latch 31 is in the locked state, a radial clamping force is applied to the brewing cup 2, pressing it firmly into the fixing base 1. Furthermore, to ensure that the latch 31 does not shift when switching between the locked and unlocked states, a guide groove can be provided on the inner wall of the locking housing 32, and the latch 31 has a guide portion that can move along the guide groove.

[0043] Continue to combine Figure 10 Each of the two latches 31 has a protruding post 314 on its first side. The outer circumferential surface of the protruding post 314 has a raised ridge and forms a spring seat. The elastic component 33 is a spring, with both ends of the spring sleeved on the protruding post 314. By providing the spring seat, the spring can be positioned to prevent it from coming out between the two latches 31.

[0044] The following describes the assembly and disassembly process and principle of the quick-release brewing component according to an embodiment of this application: Installation of brewing cup 2: Holding the brewing cup 2, the unique matching relationship between the third cup positioning pin 23 (T-shaped) at the bottom of the brewing cup 2 and the third seat positioning hole 14 (T-shaped) at the bottom of the fixing base 1 forces and limits the assembly angle, completely eliminating the risk of incorrect assembly direction. The brewing cup 2 is then horizontally advanced through the opening of the fixing base 1 by approximately a predetermined stroke, for example, 5 cm. The two cylindrical first cup positioning pins 21 and second cup positioning pins 22 at the bottom of the brewing cup 2, and the T-shaped third cup positioning pin 23 at the bottom, are respectively inserted into the two circular first seat positioning holes 12 and second seat positioning holes 13, and the T-shaped third seat positioning hole 14 of the fixing base 1. Simultaneously, the positioning protrusion 24 on the upper part of the brewing cup 2 slides along the positioning groove 15 on the upper part of the fixing base 1. This three-stage system (hole-hole-groove) forms a gapless fit, ensuring that the brewing cup 2 has no axial wobble and no radial offset, providing a precise basic positioning for subsequent locking. During the insertion of the brewing cup 2, the locking mechanism 3 moves with the brewing cup 2 towards the fixed base 1 and gradually enters the fixed base 1. The locking head 311 of the latch 31 is pushed and squeezed by the two side walls of the fixed base 1, overcoming the resistance of the elastic component 33 and sliding inward for a predetermined stroke, for example, 5 mm. The elastic component 33 is compressed and stores energy. When the latch 31 moves to the point where the locking head 311 is aligned with the locking position 11 on the side wall of the fixed base 1, the latch 31 loses external force resistance, and the elastic component 33 instantly releases the pre-tightening force, pushing the latch 31 to reset outward so that the locking head 311 is engaged with the locking position 11 (the locking position 11 is, for example, a locking groove), forming a rigid engagement. At the moment of locking, the latch 31 applies a continuous radial inward pressing force to the outer wall of the brewing cup 2, eliminating the risk of axial movement and significantly improving the structural stability and sealing performance under high-pressure brewing conditions.

[0045] Disassembly of brewing cup 2: During disassembly, use the index finger and thumb of one hand to simultaneously press the pressing part 312 on the latches 31 on both sides of the lock case 32 (for example, apply a horizontal force of 15N on each side) to overcome the pre-tightening force of the elastic component 33 and push the two latches 31 to move inward by a preset stroke (for example, 5mm). This design forces the force to be balanced on both sides to prevent accidental unlocking caused by accidental contact on one side. After the latch head 311 is completely disengaged from the latch 11, move the brewing cup outward horizontally by 25cm. The hole-groove and the corresponding component separate without friction, avoiding the jamming problem of traditional threaded disassembly. After the brewing cup 2 is removed, release the pressing part 312 of the latch 31. The elastic component 33 pushes the latch 31 back to the initial position. No manual intervention is required throughout the process, leaving a ready state for the next assembly.

[0046] The quick-release brewing assembly of this application embodiment achieves the following: 1. Three-level precise positioning: Through the clearance fit between the first positioning hole 12 and the second positioning hole 13 in the horizontal direction and the first cup positioning pin 21 and the second cup positioning pin 22, the sliding fit between the T-shaped third positioning hole 14 and the T-shaped third cup positioning pin 23, and the fitting and limiting of the upper strip-shaped positioning protrusion 24 and the positioning groove 15, a three-dimensional positioning system is formed. This design can ensure that the brewing cup 2 is accurately inserted into the fixing base 1 at a preset angle (the angle with the vertical direction is ≤3°), which restricts its displacement from multiple dimensions, significantly improves the installation stability, and forms the core foundation for the stable installation of the brewing cup 2. 2. Symmetrical elastic buckle 31 locking: Through the symmetrical configuration of the buckles 31 on the left and right sides, and the sliding limit of the anti-dislodgement limiting protrusion 313 on the top of the buckle 31 and the inner sliding groove of the fixing base 1, the buckle 31 is effectively prevented from shifting; the cylindrical helical spring between the two buckles 31 achieves automatic reset, forming a bidirectional locking force. This structure eliminates the complex transmission gears, eccentric shafts and other components found in existing high-end models, achieving reliable locking with only a few parts such as buckles 31 and springs, greatly simplifying the structure, reducing costs and failure rates. At the same time, the tight pressure of the buckles 31 on the outer wall of the brewing cup 2 during locking ensures good fixation.

[0047] 3. Convenient and efficient assembly and disassembly process: Based on the above-mentioned positioning and locking mechanism, the assembly and disassembly process is quick and easy. During installation, the three-level positioning structure guides the insertion, and a "click" sound indicates that the device is locked in place. During disassembly, simply press the pressing part 312 of the left and right latches 31 simultaneously to compress the spring and disengage the latch head 311 from the latch position 11, completing the disassembly. No tools are required throughout the process, and it can be completed in 1 second with one hand.

[0048] This application also provides a beverage machine, which includes a frame and a drive mechanism, as well as a quick-release brewing assembly as described in any of the above embodiments. The mounting base 1 of the quick-release brewing assembly is disposed on the frame and can move along a track on the frame under the drive of the drive mechanism to switch between a powder-dispensing position and a brewing position. The brewing cup 2 of the quick-release brewing assembly is detachably mounted on the mounting base 1 and can move synchronously with the mounting base 1 when installed. Because the beverage machine of this application has a quick-release brewing assembly, it can quickly install and remove the brewing cup 2, improving operational convenience and facilitating the replacement or cleaning of the brewing cup 2.

[0049] When the beverage machine is started, the brewing cup 2 first picks up the powder in the initial position. Then, the drive mechanism moves the brewing cup 2 along the track to the brewing position, where it engages with the brewing head of the beverage machine to complete the powder pressing and brewing. After brewing, the brewing cup 2 moves back along the track. During the back-reset movement, the push rod 4 at the bottom of the brewing cup 2 is blocked, causing its top to push out of the brewing cup 2, pushing out the powder residue inside the brewing cup 2. At the same time, the push rod spring 5 is compressed, storing energy for the subsequent automatic reset of the push rod 4. As the brewing cup 2 continues to move horizontally along the track, the powder residue flows along the powder residue slide 6 to the residue receiving tray. At the same time, the push rod 4 also moves horizontally under the drive of the brewing cup 2. The obstruction acting on the push rod 4 is removed, and the push rod spring 5 slowly rebounds, driving the push rod 4 to reset. The quick-release brewing assembly is ready for the next brewing.

[0050] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
