Description

Technical Field

[0001] This application relates to the field of coffee machine technology, and in particular to a powder hopper locking mechanism and a coffee machine. Background Technology

[0002] In recent years, with the popularization of coffee culture, coffee machines have gradually become essential equipment in homes and offices. Currently, the market mainly offers two types: semi-automatic and fully automatic coffee machines. Semi-automatic coffee machines allow users to manually control the tamping force, water temperature, and pressure parameters, and can stably output a standard extraction pressure of 9 bar or higher, thus ensuring sufficient crema formation and ideal flavor. However, they are more complex to operate and require a higher level of user skill.

[0003] In contrast, fully automatic coffee machines have rapidly captured the home coffee market thanks to their one-button operation, but their product quality has long been questioned by the industry. Fundamentally, the core flaw in existing fully automatic coffee machines lies in the mechanical bottleneck of their pressure maintenance system. Related technologies typically employ a threaded gear transmission mechanism that locks the coffee powder hopper to ensure stability during extraction.

[0004] However, the 9-bar pressure required for standard coffee extraction will subject the threaded gear transmission mechanism used to drive and lock the brewing powder hopper to a huge load, which will affect the life of the mechanism in the long run. Utility Model Content

[0005] This application provides a powder container locking mechanism and a coffee machine to solve the problem in the above-mentioned related technologies where extraction at 9 Bar pressure in fully automatic coffee machines affects the lifespan of the mechanism driving the coffee machine's powder container.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a powder hopper locking mechanism for a coffee machine, comprising:

[0008] The bracket includes a first guide section;

[0009] The lifting frame is movably connected to the support along the first direction;

[0010] The brewing device is used to drive the lifting frame to move in the first direction;

[0011] The gripper is fixedly connected to the lifting frame in a first direction, and movably connected to the lifting frame in a second direction, wherein the first and second directions are approximately perpendicular; wherein,

[0012] The claw includes a second guide portion that cooperates with the first guide portion. The first guide portion is used to drive the claw to move in a second direction toward the brewer when the lifting frame moves the claw in a first direction toward the direction of the support, so that the claw locks into the brewer.

[0013] The powder hopper locking mechanism in this embodiment, through a specific connection between the jaw bracket and the lifting frame, allows the jaw to move in a first direction while simultaneously moving in a second direction, thereby locking the brewer as it is pushed in. This locking connection between the jaw and the brewer ensures the brewer remains stable during coffee machine operation, preventing accidental loosening and improving safety. Once the brewer is locked, coffee extraction can begin; for simplicity, the locked position is referred to as the extraction position. In the extraction position, because the brewer is locked by the jaw, the thrust applied to the brewer when 9 Bar pressure liquid is introduced is absorbed by the jaw, preventing it from being transmitted to the transmission mechanism that drives the brewer. This protects the structural safety of the transmission mechanism and extends its service life.

[0014] Furthermore, using the brewer to directly push the lifting mechanism to achieve automatic locking and unlocking of the chuck simplifies the structure of the powder hopper locking mechanism and reduces costs. Because the first and second directions are perpendicular, the powder hopper locking mechanism can be designed compactly, helping to save internal space in the coffee machine and allowing for a more compact design.

[0015] In one possible implementation, the mating surfaces of the first guide portion and the second guide portion include a sloped structure;

[0016] The tilt direction of the inclined plane structure is configured to convert the displacement of the jaws along the first direction into the displacement of the jaws along the second direction.

[0017] By setting the mating surface between the first guide part and the second guide part as an inclined structure, the structure of the first guide part and the second guide part can be simplified, thereby simplifying the overall design, reducing manufacturing and maintenance costs, and improving the reliability of the system.

[0018] In one possible implementation, one of the first guide portion and the second guide portion includes a guide groove structure;

[0019] The other of the first guide section and the second guide section includes a guide rod; wherein...

[0020] The guide rod is slidably set inside the guide groove structure, and part of the groove wall of the guide groove structure forms an inclined structure.

[0021] By combining the first and second guide sections into a guide groove structure and a guide rod, a precise linear motion path can be provided. The guide rod slides within the guide groove, ensuring the stability and accuracy of the motion. The precise fit between the guide groove and the guide rod reduces wear between the first and second guide sections, thereby extending the service life of the powder hopper locking mechanism and reducing maintenance requirements. Furthermore, the guide groove structure and guide rod are simple in structure and easy to manufacture, reducing processing costs.

[0022] In one possible implementation, the second guide portion is formed at the end of the claw that faces away from the brewer in a second direction; wherein...

[0023] One of the first guide section and the second guide section includes an inclined wall;

[0024] The inclined wall has a sloping structure.

[0025] This design allows the inclined wall to provide a smooth movement path, reducing abrupt changes in the gripper's movement. The combination of the inclined structure makes the change of movement direction more natural and fluid. The inclined wall can precisely guide the gripper's movement path, ensuring accuracy at specific positions, and the inclined structure further enhances this precision. The inclined structure can effectively change the direction and magnitude of the applied force, thereby achieving optimized force transmission. The curved design helps to disperse stress, reduce local stress concentration, and extend component life. The smooth curved path can reduce friction and wear, thereby reducing noise and extending the equipment's service life.

[0026] In one possible implementation, in the second direction, the end of the chuck facing the brewer has a locking part;

[0027] The outside of the brewer is provided with a locking part that matches the locking part;

[0028] When a portion of the locking part is embedded within the engaging part, the locking part and the engaging part are locked together.

[0029] By incorporating locking and engaging parts, a secure connection between the chuck and the brewer is ensured, preventing loosening or detachment. When the locking part engages with the engaging part, a bidirectional limiting lock is formed, restricting relative movement between the chuck and the brewer in both directions. This stable locking connection helps reduce vibration and noise during coffee extraction, thereby extending the lifespan of the coffee machine.

[0030] In one possible implementation, one of the locking and engaging parts includes a locking tooth that extends circumferentially along the brewer;

[0031] The other of the locking and engaging portions includes an alveolar bone that mates with the tooth.

[0032] By positioning the latches and grooves along the circumference of the brewer, the connection between the locking and engaging parts is made more secure. Due to the matching design of the latches and grooves, the components effectively prevent rotation and slippage after locking, improving the stability of the brewer during coffee extraction. The design of the latches and grooves provides a self-locking function, preventing accidental loosening of the connection without external force, thus improving the safety and reliability of the system. The robust locking connection helps reduce vibration and noise generated during coffee extraction, thereby extending the lifespan of the coffee machine.

[0033] In one possible implementation, there are multiple tooth catchers and multiple alveoli; among them,

[0034] Multiple teeth are arranged along the first direction, and multiple alveoli are arranged along the first direction.

[0035] By incorporating multiple locking teeth and grooves, multiple contact points can be provided, thereby dispersing the stress applied to the connection and improving the stability of the locking connection. Due to the presence of multiple locking teeth and grooves, the force applied to the connection can be distributed more evenly, reducing localized stress concentration, minimizing component wear and fatigue, and extending the lifespan of the powder hopper locking mechanism. Using multiple locking teeth and grooves also improves the fault tolerance of the powder hopper locking mechanism; if one locking tooth or groove wears or is damaged, the others can still maintain the integrity of the connection.

[0036] In one possible implementation, the lifting frame includes a first receiving cavity and an assembly cavity that are interconnected;

[0037] In the second direction, the assembly cavity is located outside the first receiving cavity;

[0038] The chuck is movably positioned within the assembly cavity along the second direction;

[0039] In the second direction, the end of the claw facing the first receiving cavity can pass through the assembly cavity and enter the first receiving cavity, so that the claw can be locked and connected with the brewer in the first receiving cavity.

[0040] By placing the assembly cavity outside the first receiving cavity, space can be utilized more effectively. This design allows for the accommodation and operation of more components without increasing the size of the powder hopper locking mechanism, thus promoting the miniaturization of the powder hopper locking mechanism. The chuck can move in the second direction and pass through the assembly cavity into the first receiving cavity. This design provides flexible motion control, allowing the chuck to engage with the brewer when needed and easily disengage when not needed. Because the chuck needs to pass through the assembly cavity to enter and lock into the first receiving cavity, this design prevents misoperation and ensures that locking is only achieved under correct conditions.

[0041] In one possible implementation, the lifting frame includes a sealing plug located within a first receiving cavity; wherein...

[0042] A receiving space for accommodating the brewer is provided between the sealing plug and the cavity wall of the first receiving cavity. When the claw is locked with the brewer, part of the structure of the brewer is located in the receiving space.

[0043] The brewing device includes a brewing chamber, which is used to hold the coffee to be extracted;

[0044] The sealing plug is used to seal the coffee to be extracted inside the brewing chamber when the jaws are locked in the brewer.

[0045] By incorporating a sealing plug, the coffee to be extracted is ensured to be sealed within the brewing chamber when the chuck and brewer are locked together. This ensures extraction in a sealed environment, optimizing pressure and temperature conditions, thereby improving extraction efficiency and flavor quality. The sealed environment helps preserve the coffee's aroma and flavor, preventing aroma loss during extraction and providing a richer, more robust coffee experience. The sealed design prevents external air and contaminants from entering the brewing chamber, reducing the risk of coffee oxidation and contamination, thus improving coffee quality and safety. The sealing plug design ensures effective sealing and extraction only when the chuck and brewer are properly locked together. This reduces the risk of misoperation and improves the safety and reliability of the powder hopper locking mechanism.

[0046] In one possible implementation, the brewer includes a drive unit for driving the brewer to move along a first direction; wherein...

[0047] The drive unit is located at the bottom of the brewer.

[0048] By placing the drive unit at the bottom of the brewer, the drive structure is simplified, reducing the number and complexity of transmission components. This not only lowers manufacturing costs but also reduces potential points of failure and improves the reliability of the powder hopper locking mechanism. The bottom-driven design frees up space in the upper part of the brewing chamber, allowing it to focus on accommodating and processing coffee. This space optimization contributes to a more compact device design.

[0049] In one possible implementation, the support includes a second receiving cavity, and the first guide portion is located within the second receiving cavity;

[0050] At least part of the lifting frame is located in the second receiving cavity, and the assembly cavity is in communication with the second receiving cavity.

[0051] By integrating multiple functional components within the second housing cavity, the compactness of the powder hopper locking mechanism can be improved, helping to reduce its overall size and save space. The second housing cavity provides physical protection for the internal components, preventing the effects of dust, moisture, and other external environmental factors. This helps extend the service life of the powder hopper locking mechanism and improve its reliability.

[0052] A second aspect of this application provides a coffee machine, including a device body and a powder hopper locking mechanism as described in the first aspect above.

[0053] The coffee machine in this embodiment of the application, by setting the powder compartment locking mechanism of the first aspect, can improve the stability of coffee extraction and extend the service life of the coffee machine. Attached Figure Description

[0077] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0078] With the popularization of coffee culture, coffee machines have gradually become essential equipment in homes and offices. Currently, the market mainly offers two types: semi-automatic and fully automatic coffee machines. Semi-automatic coffee machines allow users to manually control the tamping force, water temperature, and pressure parameters, and can stably output a standard extraction pressure of 9 bar or higher, thus ensuring sufficient crema formation and ideal flavor. However, they are more complex to operate and require a higher level of user skill.

[0079] In contrast, fully automatic coffee machines have rapidly captured the home market with their one-button operation, but their product quality has long been questioned by the industry. Ultimately, the core flaw of existing fully automatic coffee machines lies in the mechanical bottleneck of their pressure maintenance system.

[0080] In related technologies, fully automatic coffee machines typically employ a threaded gear transmission mechanism that drives the brewing powder hopper to lock the hopper in order to ensure that the brewing powder hopper remains stable during extraction.

[0081] However, the 9-bar pressure required for standard coffee extraction will place an extremely high load on the threaded gear transmission mechanism used to drive and lock the brewing powder hopper, causing unstable pressure during the extraction process, affecting the extraction effect, and impacting the lifespan of the mechanism with long-term use.

[0082] To address the aforementioned technical problems, this application provides a powder container locking mechanism that uses a locking claw to connect with the brewer, ensuring the brewer remains stable during coffee machine operation, preventing accidental loosening, improving pressure stability during extraction, guaranteeing extraction results, and enhancing safety.

[0083] The powder compartment locking mechanism and coffee machine provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0084] Figure 1 This is a schematic diagram of the structure of a coffee machine provided in an embodiment of this application. Figure 2 This is a cross-sectional structural diagram of a powder hopper locking mechanism provided in an embodiment of this application.

[0085] It should be noted that, for ease of description, in this embodiment, the height direction of the coffee machine is taken as the z-direction, and the radial direction of the brewer is taken as the x-direction.

[0086] This application provides a coffee machine 1000, such as... Figure 1 As shown, the coffee machine 1000 may include a device body 300, which may include a brewing component 400 and an extraction component 500. A portion of the structure of the brewing component 400 and a portion of the structure of the extraction component 500 form a powder container locking mechanism 100. This ensures the stability of coffee extraction and guarantees the extraction effect. The powder container locking mechanism 100 in the embodiments of this application will be described below with reference to the accompanying drawings.

[0087] This application provides a powder hopper locking mechanism 100 for use in a coffee machine 1000, such as... Figure 2As shown, the powder hopper locking mechanism 100 may include a bracket 10, a lifting frame 20, a brewer 40, and a locking claw 30. The lifting frame 20 is movably connected to the bracket 10 along a first direction. The locking claw 30 is fixedly connected to the lifting frame 20 in the first direction, and is movably connected to the lifting frame 20 in a second direction. The first direction and the second direction are substantially perpendicular. The first direction can be the height direction of the coffee machine 1000, which is the z-direction in the figure. The second direction can be the radial direction of the brewer 40, which is the x-direction in the figure.

[0088] It should be noted that "the first direction and the second direction are substantially perpendicular" means that the angle between the first direction and the second direction is 90° or close to 90°. For example, angles between the first direction and the second direction ranging from 85° to 90° and from 90° to 95° can be considered substantially perpendicular. Specifically, when the angles between the first direction and the second direction are 85°, 86°, 87°, 88°, 89°, 91°, 92°, 93°, 94°, and 95°, the first direction and the second direction are all substantially perpendicular.

[0089] It is understandable that the claw 30 and the lifting frame 20 are fixedly connected in the first direction (z direction). Here, "fixedly connected" means that the claw 30 and the lifting frame 20 do not move relative to each other in the first direction (z direction). This can also be understood as the lifting frame 20 being able to move the claw 30 along the first direction (z direction). The claw 30 and the lifting frame 20 are movably connected in the second direction, meaning that the claw 30 can move relative to the lifting frame 20 in the second direction (x direction).

[0090] For example, the brewer 40 can be movable relative to the device body 300. For instance, the brewer 40 may include a coffee grounds receiving position and an extraction position. The brewer 40 can receive coffee grounds at the coffee grounds receiving position and extract coffee at the extraction position. When the brewer 40 is in the extraction position, the brewer 40 and the support 10 are positioned opposite each other along a first direction, with the support 10 located above the brewer 40. The brewer 40 can be used to drive the lifting frame 20 to move along the first direction (z-direction). For example, the brewer 40 can be used to drive the lifting frame 20 to move upwards along the first direction (z-direction).

[0091] like Figure 2 and Figure 3As shown, the bracket 10 may include a first guide portion 12, and the claw 30 may include a second guide portion 31 that cooperates with the first guide portion 12. The first guide portion 12 and the second guide portion 31 are connected in cooperation. The first guide portion 12 can be used to drive the claw 30 to move in the second direction (x direction) towards the brewer 40 when the lifting frame 20 drives the claw 30 to move in the first direction (z direction) towards the direction closer to the bracket 10, so that the claw 30 is locked and connected with the brewer 40.

[0092] The powder hopper locking mechanism 100 in this embodiment, through a specific connection between the jaw 30 bracket 10 and the lifting frame 20, allows the jaw 30 to move in the first direction while simultaneously moving in the second direction, thereby locking the brewer 40 as it is pushed in. The locking connection between the jaw 30 and the brewer 40 ensures the brewer 40 remains stable during coffee machine operation, preventing accidental loosening and improving safety. Once the brewer 40 is locked, coffee extraction can begin; for simplicity, the locked position is referred to as the extraction position. In the extraction position, because the brewer 40 is locked by the jaw 30, the thrust applied to the brewer 40 when 9 Bar pressure liquid is introduced is absorbed by the jaw 30, preventing it from being transmitted to the transmission mechanism that drives the brewer 40. This protects the structure of the transmission mechanism and extends its service life.

[0093] Furthermore, by using the brewer 40 to directly push the lifting frame 20 to achieve automatic locking and unlocking of the chuck 30, the structure of the powder hopper locking mechanism 100 can be simplified, reducing costs. Since the first and second directions are perpendicular, the powder hopper locking mechanism 100 can be designed compactly, helping to save internal space in the coffee machine and allowing for a more compact design.

[0094] It should be noted that there can be multiple clamps 30. Multiple clamps 30 are arranged at intervals along the circumference of the brewer 40, and the multiple clamps 30 are evenly distributed in the circumference of the brewer 40. This allows the locking force of the clamps 30 on the brewer 40 to be evenly distributed in the circumference of the brewer 40, reducing stress concentration.

[0095] In this embodiment of the application, the number of claws 30 can be two, three, four or five, etc. In this embodiment of the application, the number of claws 30 is not further limited.

[0096] In some embodiments, see continue to see Figure 2As shown, the mating surfaces of the first guide portion 12 and the second guide portion 31 may include an inclined surface structure 121. The inclined direction of the inclined surface structure 121 is configured to convert the displacement of the pawl 30 along the first direction (z direction) into the displacement of the pawl 30 along the second direction (x direction).

[0097] For example, the inclined structure 121 includes a first end and a second end disposed along the x-direction, with the second end closer to the brewer 40 relative to the first end. In the z-direction, the second end is located above the first end. This arrangement allows the claw 30 to gradually move along the inclined structure 121 towards the brewer 40 along the x-direction as it moves upward along the z-direction following the lifting frame 20.

[0098] It should be noted that the inclined structure 121 refers to a continuous surface structure that is set at a certain angle with the x-direction or z-direction, including but not limited to planes, curved surfaces, concave and convex surfaces, etc., which presents an inclined state in the overall structure and can be regarded as the inclined structure 121.

[0099] By setting the mating surface between the first guide portion 12 and the second guide portion 31 as an inclined structure 121, the structure of the first guide portion 12 and the second guide portion 31 can be simplified, thereby simplifying the overall design, reducing manufacturing and maintenance costs, and improving the reliability of the system.

[0100] In one possible implementation, one of the first guide portion 12 and the second guide portion 31 includes a guide groove structure. The other of the first guide portion 12 and the second guide portion 31 includes a guide rod. The guide rod is slidably disposed within the guide groove structure, and a portion of the groove wall of the guide groove structure forms an inclined surface structure 121.

[0101] Combination Figure 2 and Figure 3 As shown, the first guide part 12 can be a guide groove structure, and the second guide part 31 can be a guide rod. This can reduce the difficulty of processing and assembly.

[0102] Of course, in some other embodiments, the first guide portion 12 can be a guide rod, and the second guide portion 31 can be a guide groove structure. In the embodiments of this application, the specific structure of the first guide portion 12 and the second guide portion 31 is not further limited.

[0103] By combining the first guide portion 12 and the second guide portion 31 into a guide groove structure and a guide rod, a precise linear motion path can be provided. The guide rod slides within the guide groove, ensuring the stability and accuracy of the motion. The precise fit between the guide groove and the guide rod reduces wear between the first guide portion 12 and the second guide portion 31, thereby extending the service life of the powder hopper locking mechanism 100 and reducing maintenance requirements. Furthermore, the guide groove structure and guide rod have a simple structure and are easy to manufacture, reducing processing costs.

[0104] like Figure 3 As shown, the two second guide portions 31 are located on both sides of the claw 30 perpendicular to the first direction (z direction), and both second guide portions 31 are cylindrical structures, which reduces the contact area between the second guide portion 31 and the first guide portion 12, thereby reducing the wear between the second guide portion 31 and the first guide portion 12.

[0105] See Figure 2 As shown, the claw 30 has an internal accommodating space 33, and an elastic member 34 is provided in the accommodating space 33. In the x direction, one end of the elastic member 34 abuts against the inner wall of the accommodating space 33, and the other end abuts against the second guide part 31. This can alleviate the impact force between the first guide part 12 and the second guide part 31, reduce stress concentration, and improve the service life of the first guide part 12 and the second guide part 31.

[0106] Of course, in some embodiments, the elastic element 34 may not be provided inside the claw 30. In the embodiments of this application, the specific structure of the claw 30 is not further limited.

[0107] Correspondingly, such as Figure 4 As shown, there can be two first guide portions 12. The two first guide portions 12 can be arranged opposite each other on both sides of the claw 30 along a direction perpendicular to the first direction, and one first guide portion 12 corresponds to one second guide portion 31. Figure 4 Only one first guide section 12 is shown in the image.

[0108] See Figure 4 As shown, the first guide portion 12 may include a bottom wall 14 and two side walls 13, which are disposed opposite to each other, and an inclined structure 121 is formed on the two side walls 13. When the second guide portion 31 is located inside the first guide portion 12, it abuts against at least one of the two side walls 13 of the first guide portion 12, and the top end of the second guide portion 31 contacts the bottom wall 14 of the first guide portion 12, thereby reducing the wobbling of the chuck 30. The inclined structure 121 may be formed on the side wall 13 of the first guide portion 12.

[0109] In other embodiments, such as Figure 5 As shown, the second guide portion 31 may be formed at the end of the claw 30 that is away from the brewer 40 in the second direction (x direction). That is, the end of the claw 30 that is away from the brewer 40 serves as the second guide portion 31. One of the first guide portion 12 and the second guide portion 31 may include an inclined wall with a sloped structure 121 formed on it.

[0110] For example, the first guide portion 12 includes an inclined wall with a beveled structure 121 formed on the inclined wall. The second guide portion 31 is located at the end of the claw 30 away from the brewer 40, and the second guide portion 31 can be a smooth arc-shaped structure, which can reduce wear between the first guide portion 12 and the second guide portion 31 and improve the service life of the claw 30 and the bracket 10.

[0111] It should be noted that in the embodiments of this application, "orientation" refers to orientation in a broad sense and is not limited to a front-facing arrangement, and "away from" refers to away from in a broad sense and is not limited to a back-to-back parallel arrangement.

[0112] This design allows the inclined wall to provide a smooth movement path, reducing abrupt changes in the movement of the jaws 30. The combination of the inclined structure 121 makes the change in movement direction more natural and fluid. The inclined wall precisely guides the movement path of the jaws 30, ensuring accuracy at specific positions, and the inclined structure 121 further enhances this precision. The inclined structure 121 can effectively change the direction and magnitude of the applied force, thereby achieving optimized force transmission. The curved design helps to disperse stress, reduce local stress concentration, and extend component life. The smooth curved path reduces friction and wear, thereby reducing noise and extending the equipment's lifespan.

[0113] It should be noted that the first guide portion 12 may include both a guide groove structure and an inclined wall, which can improve the stability of the relative movement between the first guide portion 12 and the second guide portion 31, and ensure movement accuracy and precision at a specific position.

[0114] In the second direction (x direction), the end of the claw 30 facing the brewer 40 is provided with a locking part 32 (see...). Figure 3 As shown). Figure 6 As shown, the outer side of the brewer 40 is provided with a locking part 43 that matches the locking part 32. When a portion of the structure of the locking part 32 is embedded in the locking part 43, the locking part 32 and the locking part 43 are locked together (see...). Figure 7 (As shown).

[0115] By providing the locking part 32 and the engaging part 43, a secure connection between the jaw 30 and the brewer 40 can be ensured, preventing loosening or detachment. When the locking part 32 engages with the engaging part 43, a bidirectional limiting lock is formed, restricting the relative movement of the jaw 30 and the brewer 40 in the first and second directions. This ensures a stable locking connection between the jaw 30 and the brewer 40. The secure locking connection helps reduce vibration and noise generated during coffee extraction, thereby extending the lifespan of the coffee machine.

[0116] For example, one of the locking portion 32 and the engaging portion 43 includes a retaining tooth that extends circumferentially along the brewer 40. The other of the locking portion 32 and the engaging portion 43 includes a groove that mates with the retaining tooth. For example, the locking portion 32 includes a retaining tooth, and the engaging portion 43 includes a groove. Alternatively, the locking portion 32 includes a groove, and the engaging portion 43 includes a retaining tooth, etc.

[0117] By aligning the jaws 30 and the grooves along the circumference of the brewer 40, the connection between the locking part 32 and the engaging part 43 is made more secure. Due to the matching design of the jaws and grooves, the components effectively prevent rotation and slippage after locking, improving the stability of the brewer 40 during coffee extraction. The design of the jaws and grooves provides a self-locking function, preventing accidental loosening of the connection without external force, thus improving the safety and reliability of the system. The robust locking connection helps reduce vibration and noise generated during coffee extraction, thereby extending the lifespan of the coffee machine.

[0118] like Figure 7 As shown, there are multiple tooth clips and multiple tooth sockets. Among them, multiple tooth clips are arranged along the first direction (z direction), and multiple tooth sockets are arranged along the first direction (z direction).

[0119] It should be noted that the number of teeth or grooves provided on the engaging part 43 can be greater than the number of teeth or grooves on the locking part 32. This allows the brewer 40 to have more space to lock with the claw 30, ensuring that the claw 30 can be locked and connected with the brewer 40.

[0120] By setting multiple locking teeth and multiple tooth recesses, multiple contact points can be provided, thereby dispersing the stress applied at the connection and improving the stability of the locking connection. Due to the presence of multiple locking teeth and tooth recesses, the force applied at the connection can be distributed more evenly, reducing local stress concentration, decreasing component wear and fatigue, and extending the lifespan of the powder hopper locking mechanism 100. Using multiple locking teeth and tooth recesses improves the fault tolerance of the powder hopper locking mechanism 100; if one locking tooth or tooth recess wears or is damaged, the other locking teeth and tooth recesses can still maintain the integrity of the connection.

[0121] In one possible implementation, combining Figure 7 and Figure 8 As shown, the lifting frame 20 may include a first receiving cavity 21 and an assembly cavity 22 that are interconnected. In the second direction (x direction), the assembly cavity 22 is located outside the first receiving cavity 21. A claw 30 is movably disposed within the assembly cavity 22 along the second direction (x direction). In the second direction (x direction), one end of the claw 30 facing the first receiving cavity 21 can pass through the assembly cavity 22 and enter the first receiving cavity 21, so that the claw 30 is locked and connected to the brewer 40 within the first receiving cavity 21.

[0122] It should be noted that the structure of the gripper 30 matches the structure of the assembly cavity 22. The assembly cavity 22 is used to restrict the movement of the gripper 30 relative to the lifting frame 20 along the z-direction and guide the movement of the gripper 30 along the x-direction. The structure of the assembly cavity 22 is related to the structure of the gripper 30. In this embodiment, the specific structures of the gripper 30 and the assembly cavity 22 are not further limited.

[0123] By placing the assembly cavity 22 outside the first receiving cavity 21, space can be utilized more effectively. This design allows for the accommodation and operation of more components without increasing the size of the powder hopper locking mechanism 100, which is beneficial for the miniaturization of the powder hopper locking mechanism 100. The chuck 30 can move along the second direction (x direction) and pass through the assembly cavity 22 into the first receiving cavity 21. This design provides flexible motion control, allowing the chuck 30 to lock into the brewer 40 when needed and easily disengage when not needed. Since the chuck 30 needs to pass through the assembly cavity 22 to enter the first receiving cavity 21 and lock, this design prevents misoperation and ensures that locking can only be achieved under the correct conditions.

[0124] See also Figure 7 As shown, the brewer 40 may include a brewing chamber 41 for containing coffee 200 to be extracted. The brewer 40 may also include a drive unit 42 for driving the brewer 40 to move along a first direction (z direction).

[0125] For example, the powder hopper locking mechanism 100 may also include a drive member connected to the drive unit 42, the drive member being tractively connected to the drive unit 42, thereby driving the brewer to move along the first direction via the drive member and the drive unit.

[0126] For example, the drive unit 42 may include a rack structure that extends along a first direction (z direction), and the drive member may include a gear structure that can drive the rack structure to move along the first direction (z direction) by rotating the gear structure.

[0127] Of course, in other embodiments, the driving part and the driving member can be configured with other structures. In the embodiments of this application, the specific structure of the driving part 42 and the driving member is not further limited, as long as they can drive the brewer 40 to move along the first direction (z direction).

[0128] For example, the drive unit 42 may be located at the bottom of the brewer 40. When the coffee to be extracted 200 is located in the brewing chamber 41, the coffee to be extracted 200 is located at the top of the drive unit 42. When the brewer 40 is driven to move along the first direction (z direction) towards the lifting frame 20 by the drive unit, the coffee to be extracted 200 at the top of the drive unit 42 comes into contact with the lifting frame 20, thereby pushing the lifting frame 20 to move upward along the z direction.

[0129] By placing the drive unit 42 at the bottom of the brewer 40, the structure of the brewer 40 is simplified, reducing the number and complexity of transmission components. This not only lowers manufacturing costs but also reduces potential points of failure and improves the reliability of the powder hopper locking mechanism 100. The bottom-driven design frees up the upper space of the brewing chamber 41, allowing the upper part of the brewing chamber 41 to focus on containing and processing coffee. This space optimization contributes to a more compact device design.

[0130] In one possible implementation, the lifting frame 20 may include a sealing plug 23 located within the first receiving cavity 21. A receiving space for accommodating the brewer 40 is provided between the sealing plug 23 and the cavity wall of the first receiving cavity 21. When the claw 30 is locked with the brewer 40, a portion of the brewer 40's structure is located within this receiving space.

[0131] like Figure 7 As shown, the side wall of the brewer 40 is located within the receiving space, and the sealing plug 23 is located within the brewing chamber 41. The sealing plug 23 is used to seal the coffee to be extracted 200 within the brewing chamber 41 when the latch 30 is locked into the brewer 40. In other words, when the sealing plug 23 is located within the brewing chamber 41, it can seal against the inner wall of the brewing chamber 41. When the coffee to be extracted 200 is located between the sealing plug 23 and the drive unit 42, it can seal the coffee to be extracted between the sealing plug 23 and the drive unit 42.

[0132] By incorporating the sealing plug 23, the coffee to be extracted 200 is sealed within the brewing chamber 41 when the jaws 30 are locked in place with the brewer 40. This ensures extraction in a sealed environment, optimizing pressure and temperature conditions and improving extraction efficiency and flavor quality. The sealed environment helps preserve the aroma and flavor of the coffee, preventing aroma loss during extraction and providing a richer, more robust coffee experience. The sealed design prevents external air and contaminants from entering the brewing chamber 41, reducing the risk of oxidation and contamination, thus improving coffee quality and safety. The sealing plug 23 ensures effective sealing and extraction only when the jaws 30 are properly locked in place with the brewer 40. This reduces the risk of misoperation and enhances the safety and reliability of the powder container locking mechanism 100.

[0133] like Figure 9 As shown, the support 10 may include a second receiving cavity 11, and a first guide portion 12 is located within the second receiving cavity 11. At least a portion of the lifting frame 20 is located within the second receiving cavity 11, and the assembly cavity 22 communicates with the second receiving cavity 11. The second receiving cavity 11 has a reserved space in the z-direction, which provides sufficient space for the lifting frame 20 to move in the z-direction, preventing the lifting frame 20 from colliding with the support 10 during its ascent.

[0134] By integrating multiple functional components within the second receiving cavity 11, the compactness of the powder hopper locking mechanism 100 is improved, helping to reduce its overall size and save space. The second receiving cavity 11 provides physical protection for the internal components, preventing the effects of dust, moisture, and other external environmental factors. This helps extend the service life of the powder hopper locking mechanism 100 and improve its reliability.
