Description

Technical Field

[0001] This invention relates to the field of coffee machines, and in particular to a coffee brewing method and apparatus. Background Technology

[0002] In the coffee brewing process, the extraction unit is one of the core components that holds the coffee grounds, completes the collecting, tamping, and extraction processes, and its removal is a crucial aspect of the daily use and maintenance of the coffee machine. Currently, the design of the extraction unit in existing coffee machines presents a core contradiction: the coffee grounds container must either be reliably locked to ensure stable operation, or the locking is unreliable for easy removal and maintenance. Existing coffee machines do not have a design that simultaneously ensures both reliable locking of the coffee grounds container and easy removal. Summary of the Invention

[0003] Therefore, it is necessary to provide a coffee brewing method and device to address the problem that existing coffee machines do not have a design that ensures both reliable locking of the coffee powder container and convenient removal.

[0004] A coffee brewing method includes: S1, inserting an extraction component into a movable support through a side opening of the coffee machine housing, and locking the extraction component to the movable support by a locking component; S2, automatically controlling the movable support to move on a track assembly, causing the extraction component to sequentially perform the processes of receiving coffee powder, tamping coffee powder, and extraction; S3, after extraction, automatically controlling the movable support to move towards the side opening, and when the movable support moves to a preset unlocking position, the extraction component automatically unlocks, and the ejector component drives the extraction component to move a preset distance relative to the movable support towards the side opening; S4, after the extraction component has moved the preset distance, a buffer assembly limits the extraction component, restricting the movement stroke of the extraction component.

[0005] The first aspect of this application discloses a coffee brewing method. Step S1 involves inserting the extraction component into a movable support through a side opening in the coffee machine housing and locking it in place. Compared to the traditional front-insertion design, this design eliminates the need for an opening on the front of the coffee machine for inserting the extraction component, effectively avoiding the disruption to the overall appearance and aesthetics of the coffee machine and improving its appearance quality. Step S2 executes the powder receiving, tamping, and extraction processes. Specifically, the guiding action of the track component ensures precise and stable movement of the movable support, thereby ensuring that the extraction component accurately aligns with the powder outlet of the grinding component during powder receiving; it also ensures that the extraction component is positioned below the tamping component, ensuring proper tamping. Step S3 effectively solves the problem in existing technologies where the extraction component is difficult to remove after reliable locking. This design eliminates the need for manual unlocking and laborious gripping. Automated control links the unlocking and ejection actions, allowing for immediate ejection after unlocking. The extraction component ejects a preset distance (approximately 20 mm) and is exposed at the side opening for easy user access, significantly improving the convenience of maintenance and balancing locking reliability with ease of removal. Step S4 effectively prevents excessive force during ejection from pushing the extraction component out, which could cause it to detach from the movable support and fall, negatively impacting the user experience. Preferably, in step S2, the automatic control of the movable support's movement on the track assembly involves installing a motor inside the coffee machine housing with a gear. The gear meshes with the movable support, causing it to move as the motor drives it.

[0006] In one embodiment, step S1 specifically comprises the following steps: S11, inserting the extraction component into the receiving space of the movable support through the side opening of the coffee machine housing; S12, pushing the extraction component to a preset installation position; S13, when the extraction component reaches the preset installation position, the locking component engages with the extraction component. The design of step S11 ensures reliable insertion of the extraction component while avoiding openings on the front of the coffee machine housing that would affect the overall appearance of the coffee machine. The design of step S12 prevents locking failure due to positional deviation, ensuring smooth subsequent locking operations. The design of step S13 ensures reliable locking of the extraction component, preventing loosening or displacement during subsequent operations, thus solving the problem of unreliable locking in existing technologies.

[0007] In one embodiment, step S2 specifically comprises the following steps: S21, the automatic control movable support moves to the powder receiving station, positioning the extraction component below the powder outlet of the grinding component, completing the powder receiving process; S22, the automatic control movable support moves to the tamping station, and the tamping motor controls the tamper to compress the coffee powder into a cake, completing the tamping process; S23, hot water is injected into the extraction component to brew and extract the coffee cake, completing the extraction process. Step S21 ensures that the extraction component aligns with the powder outlet of the grinding component, guaranteeing accurate powder entry into the extraction component. Step S22 ensures uniform cake density, preventing loose or clumpy cakes and ensuring even hot water penetration during subsequent extraction, improving the coffee's taste and quality. Specifically, the tamping motor is mounted on a track assembly, and its motor shaft is threadedly connected to the tamper, driving the tamper up and down when the motor shaft rotates. Step S23 ensures sufficient contact between the hot water and the uniformly compacted cake, guaranteeing efficient extraction of the coffee's effective components.

[0008] In one embodiment, the specific steps of automatically controlling the movable support to move towards the side opening in step S3, and automatically unlocking the extraction component when the movable support moves to the preset unlocking position, are as follows: S31, automatically control the movable support to move towards the side opening to the guide position, so that the locking member abuts against the guide block on the inner side of the coffee machine housing; S32, continue to automatically control the movable support to move towards the preset unlocking position, so that the locking member moves along the guide block and gradually moves in the direction of unlocking the extraction component; S33, when the movable support reaches the preset unlocking position, the locking member and the extraction component are completely separated, and the extraction component is unlocked. The design of step S31, which makes the locking member abut against the guide block on the inner side of the housing, provides a guarantee for the subsequent movement of the locking member along the guide block and the unlocking, ensuring that the unlocking action is started in an orderly manner. The design of step S32, which makes the movement of the locking member blocked by the guide block, interrupts the tendency of the locking member to move with the movable support. The locking member can only move along the guide block, so that the locking member is displaced relative to the movable support, thereby gradually unlocking the extraction component. The design of step S33 ensures complete unlocking, avoiding situations where insufficient unlocking prevents the extraction component from ejecting smoothly, and ensuring a smooth subsequent retrieval and maintenance process.

[0009] In one embodiment, the guide block has a first guide ramp, and the locking member has a second guide ramp. In step S31, the locking member abuts against the guide block by the second guide ramp abutting against the first guide ramp. In step S32, the locking member moves along the guide block by the second guide ramp sliding relative to the first guide ramp, causing the locking member to gradually move away from the extraction component. The abutting of the second guide ramp against the first guide ramp in step S31 provides a stable contact basis for the subsequent relative sliding of the ramps, further ensuring the orderly and smooth initiation of the unlocking action and laying a reliable foundation for the subsequent unlocking process. The relative sliding of the second guide ramp against the first guide ramp in step S32 interrupts the tendency of the locking member to move together with the movable support, allowing the locking member to move smoothly and gradually away from the extraction component, achieving a gradual unlocking of the extraction component, avoiding abrupt or stuck unlocking actions, reducing component wear, and ensuring the stability and smoothness of the unlocking process.

[0010] In one embodiment, the extraction component is provided with a first limiting groove, and a first elastic element is provided between the locking member and the movable support member. In step S1, locking the extraction component to the movable support member by the locking member specifically means that the locking member is engaged in the first limiting groove under the action of the first elastic element to lock the extraction component. In step S32, moving the locking member along the guide block and gradually moving towards the direction of unlocking the extraction component specifically means that when the second guide slope slides along the first guide slope, it overcomes the elastic force of the first elastic element, causing the locking member to gradually exit the first limiting groove. During the locking process in S1, the locking member is engaged in the first limiting groove of the extraction component under the action of the elastic force of the first elastic element. The elastic force of the first elastic element ensures that the locking member and the first limiting groove are tightly engaged, forming a firm lock. During the unlocking process in S32, when the second guide slope slides along the first guide slope, the locking member overcomes the elastic force of the first elastic element and gradually exits the first limiting groove. The first elastic element provides stable elastic support for locking and can also play a buffering role during unlocking, making the action of the locking member exiting the first limiting groove smooth.

[0011] In one embodiment, an electromagnet is provided on the movable support, the locking element is a permanent magnet, and the extraction component has a first limiting groove. In step S1, locking the extraction component to the movable support using the locking element specifically involves the electromagnet generating a repulsive force on the permanent magnet, causing the permanent magnet to engage in the first limiting groove to lock the extraction component. In step S3, the automatic unlocking of the extraction component specifically involves the electromagnet generating an attractive force on the permanent magnet, causing the permanent magnet to exit the first limiting groove to unlock the extraction component. The repulsive force of the electromagnet in step S1 ensures that the permanent magnet and the first limiting groove are tightly fitted and firmly locked, effectively preventing the extraction component from loosening or shifting during subsequent processes such as powder receiving, powder pressing, and extraction, ensuring the stable operation of each process. During the unlocking process in step S3, the electromagnet switches its magnetic direction, generating an attractive force on the permanent magnet, which drives the permanent magnet to exit the first limiting groove, thus automatically unlocking the extraction component.

[0012] In one embodiment, the ejection component is an elastic energy storage element that abuts against the extraction component. In step S1, when the extraction component is locked, the elastic energy storage element is compressed and accumulates elastic force. In step S3, the ejection component drives the extraction component to move a preset distance relative to the movable support towards the side opening. Specifically, after the extraction component is unlocked, the elastic energy storage element releases its elastic force, driving the extraction component to eject a preset distance relative to the movable support towards the side opening. When the extraction component is installed and locked, it simultaneously compresses the elastic energy storage element, causing it to be compressed and accumulate elastic force. This process requires no additional power; energy storage is completed through the installation and locking action of the extraction component. The preset distance can be 20mm. This design eliminates the need for additional driving components, utilizing the energy storage and release of the elastic energy storage element to automatically eject the extraction component, solving the problem of difficulty in coordinating the locking and removal of the extraction component in the prior art.

[0013] Specifically, the elastic energy storage component includes a pushing component and a second elastic component. The pushing component is mounted on the movable support and abuts against the extraction assembly. One end of the second elastic component abuts against the pushing component, and the other end abuts against the space wall of the first limiting space. The second elastic component applies a force towards the receiving space to the pushing component. When the extraction assembly is locked, the second elastic component accumulates potential energy to achieve energy storage. After the extraction assembly is unlocked, the second elastic component releases the potential energy, precisely pushing the extraction assembly out approximately 20mm via the pushing component for easy removal. This design relies on the second elastic component and the pushing component to automatically eject the extraction assembly without additional power, adapting to the overall automatic unlocking and ejection process.

[0014] In one embodiment, the ejection component includes a driving member and a pushing block. The screw of the driving member is threadedly connected to the pushing block, and the pushing block abuts against the extraction component. In step S3, the ejection component drives the extraction component to move a predetermined distance relative to the movable support towards the side opening. Specifically, the driving member is activated, which drives the pushing block to move the extraction component relative to the movable support towards the side opening a predetermined distance. The driving member includes a drive motor and a screw. The screw is connected to the drive motor and threadedly connected to the pushing block. The pushing block includes a pushing block body and a mating block. The mating block mates with the pushing block body and is threadedly connected to the screw.

[0015] In one embodiment, the extraction component is provided with a second limiting groove. In step S4, the buffer component limits the extraction component by engaging the second limiting groove. This design of the buffer component prevents the extraction component from being suddenly pushed out and falling off.

[0016] A coffee brewing device includes: a coffee machine housing having a side opening for an extraction component to enter and exit; a track assembly disposed on and inside the coffee machine housing; a movable support movably disposed on the track assembly and movable relative to the track assembly; an extraction component disposed on the movable support; a locking member disposed on the movable support and capable of locking or unlocking the extraction component; a ejection component disposed on the movable support and located on the side of the movable support away from the side opening, the ejection component abutting against the extraction component and capable of driving the extraction component to move toward the side opening; and a buffer assembly disposed on the movable support and capable of abutting against or separating from the extraction component.

[0017] The second aspect of this application discloses a coffee brewing device that effectively solves the core contradiction in the prior art—the difficulty in coordinating the locking and removal of the extraction component—through the coordinated design of its components. Specifically, a movable support is movably mounted on a track assembly, a locking component locks the extraction component, and the movable support can move smoothly along the track assembly, providing precise guidance for the extraction component to sequentially perform the powder receiving, tamping, and extraction processes, ensuring brewing quality. When it is necessary to remove the extraction component, the extraction component unlocks, and the ejector automatically pushes the extraction component a certain distance, ensuring that the extraction component is easy to retrieve.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0022] Example 1, as Figure 1-21As shown, this embodiment discloses a coffee brewing method, including: S1, inserting the extraction component 4 into the movable support 3 through the side opening 101 of the coffee machine housing 1, and locking the extraction component 4 to the movable support 3 by the locking component 5; S2, automatically controlling the movable support 3 to move on the track component 2, so that the extraction component 4 sequentially performs the processes of receiving powder, tamping powder and extraction; S3, after extraction, automatically controlling the movable support 3 to move towards the side opening 101, and when the movable support 3 moves to a preset unlocking position, the extraction component 4 automatically unlocks, and the ejection component 6 drives the extraction component 4 to move a preset distance relative to the movable support 3 towards the side opening 101; S4, after the extraction component 4 moves the preset distance, the buffer component 7 limits the extraction component 4, restricting the movement stroke of the extraction component 4.

[0023] The first aspect of this application discloses a coffee brewing method. In step S1, the extraction component 4 is inserted into the movable support 3 through the side opening 101 of the coffee machine housing 1 and locked by the locking component 5. Compared to the traditional front-insertion design, this design eliminates the need for an opening on the front of the coffee machine for inserting the extraction component 4, effectively avoiding damage to the overall appearance and aesthetics of the coffee machine and improving its appearance quality. Step S2 executes the powder receiving, tamping, and extraction processes. Specifically, the guiding action of the track component 2 ensures the precise and stable movement of the movable support 3, thereby ensuring that the extraction component 4 accurately aligns with the powder outlet of the grinding component when receiving powder; it also ensures that the extraction component 4 is located below the tamping component, ensuring proper tamping. Step S3 effectively solves the problem in the prior art where the extraction component 4 is difficult to remove after reliable locking. This design eliminates the need for manual unlocking and laborious grasping. Automated drive links the unlocking and ejection actions, allowing for immediate ejection after unlocking. The extraction component 4 ejects a preset distance (approximately 20 mm) and is exposed at the side opening 101, facilitating user access and significantly improving the ease of maintenance. This balances locking reliability with convenient removal. Step S4 effectively prevents excessive force from ejecting the extraction component 4 during ejection, which could cause it to detach from the movable support 3 and fall, negatively impacting the user experience. Preferably, in step S2, the automatic control of the movable support 3's movement on the track assembly 2 can be achieved by installing a motor inside the coffee machine housing 1, with a gear on the motor. The gear meshes with the movable support 3, so that the movable support 3 moves as the gear rotates under the motor's drive.

[0024] like Figure 2 , Figure 6 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines the specific steps of step S1 as follows: S11, insert the extraction component 4 into the receiving space 301 of the movable support 3 through the side opening 101 of the coffee machine housing 1; S12, push the extraction component 4 to the preset installation position; S13, when the extraction component 4 reaches the preset installation position, the locking component 5 engages with the extraction component 4. The design of step S11 ensures that the extraction component 4 is reliably inserted while avoiding openings on the front of the coffee machine housing 1, which would affect the overall appearance quality of the coffee machine. The design of step S12 avoids locking failure due to positional deviation, ensuring smooth subsequent locking operations. The design of step S13 ensures that the extraction component 4 is reliably locked, preventing loosening and displacement during subsequent operations, and solving the problem of unreliable locking in the prior art.

[0025] like Figure 3 , Figure 13 and Figure 21 As shown, in addition to the features of the above embodiments, this embodiment further defines the specific steps of step S2 as follows: S21, the automatic control movable support 3 moves to the powder receiving station, so that the extraction component 4 is located below the powder outlet of the grinding component 8, completing the powder receiving process; S22, the automatic control movable support 3 moves to the powder tamping station, and the powder tamping motor 14 controls the tamper 9 to tamp the coffee powder into a cake, completing the powder tamping process; S23, hot water is injected into the extraction component 4 to brew and extract the coffee cake, completing the extraction process. The design of step S21 ensures that the extraction component 4 is aligned with the powder outlet of the grinding component 8 to receive the coffee powder, ensuring that the coffee powder falls accurately into the extraction component 4. The design of step S22 ensures that the coffee cake density is uniform, avoiding loose or clumpy coffee cakes, ensuring uniform hot water penetration during subsequent extraction, and improving the taste and quality of the extracted coffee. Specifically, the tamping motor 14 is mounted on the track assembly 2, and the motor shaft of the tamping motor 14 is threadedly connected to the tamper 9, so that the tamping motor 14 drives the tamper 9 to move up and down when the motor shaft rotates. The design of step S23 ensures that the hot water and the uniformly compacted coffee cake are in full contact, ensuring the extraction efficiency of the effective components of coffee.

[0026] like Figure 4 , Figure 6 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines the following specific steps for automatically controlling the movable support 3 to move toward the side opening 101 in step S3, and for the extraction component 4 to automatically unlock when the movable support 3 moves to the preset unlocking position: S31, automatically control the movable support 3 to move toward the side opening 101 to the guide position, so that the locking member 5 abuts against the guide block 10 on the inner side of the coffee machine housing 1; S32, continue to automatically control the movable support 3 to move toward the preset unlocking position, so that the locking member 5 moves along the guide block 10 and gradually moves toward the direction of unlocking the extraction component 4; S33, when the movable support 3 reaches the preset unlocking position, the locking member 5 is completely separated from the extraction component 4, and the extraction component 4 is unlocked. The design of step S31, which makes the locking member 5 abut against the guide block 10 on the inner side of the housing, provides a guarantee for the subsequent movement of the locking member 5 along the guide block 10 and the unlocking, ensuring that the unlocking action is started in an orderly manner. The design of step S32 ensures that the movement of the locking component 5 is blocked by the guide block 10, thus interrupting the tendency of the locking component 5 to move together with the movable support component 3. The locking component 5 can only move along the guide block 10, causing it to shift relative to the movable support component 3, thereby gradually unlocking the extraction component 4. The design of step S33 ensures complete unlocking, avoiding insufficient unlocking that would prevent the extraction component 4 from popping out smoothly, and ensuring a smooth subsequent removal and maintenance process.

[0027] like Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the guide block 10 is provided with a first guide slope 1001, and the locking member 5 is provided with a second guide slope 501; in step S31, the locking member 5 abuts against the guide block 10 specifically means that the second guide slope 501 abuts against the first guide slope 1001; in step S32, the locking member 5 moves along the guide block 10 specifically means that the second guide slope 501 slides relative to the first guide slope 1001, so that the locking member 5 gradually moves away from the extraction component 4. The abutment between the second guide slope 501 and the first guide slope 1001 in step S31 provides a stable contact basis for the subsequent relative sliding of the slopes, further ensuring the orderly and smooth start of the unlocking action, and laying a reliable foundation for the subsequent unlocking process. By sliding the second guide slope 501 relative to the first guide slope 1001 in step S32, the tendency of the locking member 5 to move together with the movable support member 3 is interrupted, and the locking member 5 can be moved away from the extraction component 4 smoothly and gradually, so as to realize the gradual unlocking of the extraction component 4, avoid the unlocking action being stiff and stuck, reduce component wear, and ensure the stability and smoothness of the unlocking process.

[0028] like Figure 6 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the extraction component 4 is provided with a first limiting groove 401, and a first elastic element 11 is provided between the locking member 5 and the movable support member 3; in step S1, locking the extraction component 4 to the movable support member 3 by the locking member 5 specifically means that the locking member 5 is engaged in the first limiting groove 401 under the action of the first elastic element 11 to lock the extraction component 4; in step S32, moving the locking member 5 along the guide block 10 and gradually moving towards the direction of unlocking the extraction component 4 specifically means that when the second guide inclined surface 501 slides along the first guide inclined surface 1001, it overcomes the elastic force of the first elastic element 11, causing the locking member 5 to gradually exit the first limiting groove 401. During the locking process in S1, the locking member 5 is engaged in the first limiting groove 401 of the extraction component 4 under the action of the elastic force of the first elastic element 11, and the elastic force of the first elastic element 11 can ensure that the locking member 5 is tightly engaged with the first limiting groove 401, forming a firm lock. During the unlocking process of S32, when the second guide slope 501 slides along the first guide slope 1001, the locking member 5 will overcome the elastic force of the first elastic member 11 and gradually exit the first limiting groove 401. The first elastic member 11 provides stable elastic support for locking and can play a buffering role during unlocking, so that the locking member 5 exits the first limiting groove 401 smoothly.

[0029] Specifically, such as Figure 8 and Figure 14-15 As shown, the movable support 3 includes a movable support block 31 and a fixed block 32. The fixed block 32 is disposed on the movable support block 31 and is located on the outside of the movable support block 31. The two ends of the first elastic member 11 abut against the fixed block 32 and the locking member 5, respectively.

[0030] like Figure 6 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the ejection component 6 is an elastic energy storage component, which abuts against the extraction component 4; when the extraction component 4 is locked in step S1, the elastic energy storage component is compressed and accumulates elastic force; in step S3, the ejection component 6 drives the extraction component 4 to move a preset distance relative to the movable support 3 toward the side opening 101, specifically: after the extraction component 4 is unlocked, the elastic energy storage component releases its elastic force, driving the extraction component 4 to eject a preset distance relative to the movable support 3 toward the side opening 101. When the extraction component 4 is installed and locked, it will simultaneously squeeze the elastic energy storage component, causing it to be compressed and accumulate elastic force. This process does not require additional power drive; energy storage can be completed by the installation and locking action of the extraction component 4. The preset distance can be 20mm. This design does not require additional drive components, and utilizes the energy storage and release of the elastic energy storage component to achieve automatic ejection of the extraction component 4, solving the problem of difficulty in coordinating the locking and removal of the extraction component 4 in the prior art.

[0031] Specifically, such as Figure 6 and Figure 7 As shown, the elastic energy storage component includes a pushing member 61 and a second elastic member 62. The pushing member 61 is disposed on the movable support member 3 and abuts against the extraction component 4. One end of the second elastic member 62 abuts against the pushing member 61, and the other end of the second elastic member 62 abuts against the space wall of the first limiting space. The second elastic member 62 is used to apply a force towards the receiving space 301 to the pushing member 61. When the extraction component 4 is locked, the second elastic member 62 accumulates potential energy to achieve energy storage operation; after the extraction component 4 is unlocked, the second elastic member 62 releases potential energy, and the pushing member 61 precisely pushes the extraction component 4 out about 20mm, achieving convenient retrieval. This design relies on the second elastic member 62 and the pushing member 61 to automatically pop out the extraction component 4 without additional power, and is compatible with the overall automatic unlocking and pop-out process.

[0032] like Figure 6 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the extraction component 4 is provided with a second limiting groove 402, and in step S4, the buffer component 7 limits the extraction component 4 specifically by: the buffer component 7 being inserted into the second limiting groove 402 to limit the extraction component 4. The design of the buffer component 7 can prevent the extraction component 4 from being pushed out suddenly and falling off.

[0033] Example 2, as Figure 10-12 and Figure 18-19 As shown, the ejection assembly includes a driving component 63 and a pushing block 64. The screw of the driving component 63 is threadedly connected to the pushing block 64, and the pushing block 64 abuts against the extraction component 4. In step S3, the ejection assembly drives the extraction component 4 to move a preset distance relative to the movable support 3 toward the side opening 101. Specifically, the driving component 63 is activated, which drives the pushing block 64 to move the extraction component 4 relative to the movable support 3 toward the side opening 101 a preset distance. The driving component 63 includes a driving motor 631 and a screw 632. The screw 632 is connected to the driving motor 631 and threadedly connected to the pushing block 64. The pushing block 64 includes a pushing block body 641 and a mating block 642. The mating block 642 mates with the pushing block body 641 and is threadedly connected to the screw 632. This design allows for precise control of the ejection distance of the extraction component 4 and provides good self-locking.

[0034] Example 3, as Figure 10 and Figure 12As shown, an electromagnet 12 is provided on the movable support 3, a permanent magnet 13 is provided on the locking component 5, and the extraction component 4 is provided with a first limiting groove 401. In step S1, locking the extraction component 4 to the movable support 3 by the locking component 5 specifically involves the electromagnet 12 generating a repulsive force on the permanent magnet 13, causing the permanent magnet 13 to engage in the first limiting groove 401 to lock the extraction component 4. In step S3, automatically unlocking the extraction component 4 specifically involves the electromagnet 12 generating an attractive force on the permanent magnet 13, causing the permanent magnet 13 to exit the first limiting groove 401 to unlock the extraction component 4. The repulsive force of the electromagnet 12 in step S1 ensures that the permanent magnet 13 is tightly fitted to the first limiting groove 401 and is firmly locked, effectively preventing the extraction component 4 from loosening or shifting during subsequent processes such as powder receiving, powder pressing, and extraction, thus ensuring the stable operation of each process. During the unlocking process in step S3, the electromagnet 12 switches the magnetic direction to generate an attractive force on the permanent magnet 13. The attractive force can drive the permanent magnet 13 out of the first limiting groove 401, thereby realizing the automatic unlocking of the extraction component 4.

[0035] Example 4, as Figure 1-22 As shown, this embodiment discloses a coffee brewing device, including: a coffee machine housing 1, the coffee machine housing 1 having a side opening 101 for an extraction component 4 to enter and exit; a track assembly 2, the track assembly 2 being disposed on the coffee machine housing 1 and located inside the coffee machine housing 1; a movable support member 3, the movable support member 3 being movably disposed on the track assembly 2, the movable support member 3 being movable relative to the track assembly 2; an extraction component 4, the extraction component 4 being disposed on the movable support member 3; a locking member 5, the locking member 5 being disposed on the movable support member 3, the locking member 5 being capable of locking or unlocking the extraction component 4; an ejection component 6, the ejection component 6 being disposed on the movable support member 3 and located on the side of the movable support member 3 away from the side opening 101, the ejection component 6 abutting against the extraction component 4, the ejection component 6 being capable of driving the extraction component 4 to move toward the side opening 101; and a buffer component 7, the buffer component 7 being disposed on the movable support member 3, the buffer component 7 being capable of abutting against or separating from the extraction component 4.

[0036] The second aspect of this application discloses a coffee brewing device that effectively solves the core contradiction in the prior art—the difficulty in coordinating the locking and unlocking of the extraction component 4—through the coordinated design of its components. Specifically, a movable support 3 is movably mounted on a track assembly 2, and a locking component 5 locks the extraction component 4. The movable support 3 can move smoothly along the track assembly 2, providing precise guidance for the extraction component 4 to sequentially perform the powder receiving, tamping, and extraction processes, ensuring brewing quality. When it is necessary to remove the extraction component 4, it unlocks, and an ejector 6 automatically pushes the extraction component 4 a certain distance, ensuring that the extraction component 4 is easy to retrieve.

[0037] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
