Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to an integrated structure for scraping and feeding powder and a brewing device. Background Technology

[0002] In existing technologies, the powder scraping and feeding structures of brewers are set up separately, resulting in a larger overall size of the brewer. This not only requires more space and increases the cost of equipment storage and transportation, but also increases the complexity of mechanical transmission and the risk of failure. Furthermore, poor coordination between components makes it difficult to accurately match the powder scraping and feeding rhythms. Utility Model Content

[0003] Therefore, it is necessary to address the issue of separating the powder scraping structure and the feeding structure in a brewing device by providing an integrated powder scraping and feeding structure and a brewing device.

[0004] A powder scraping and feeding integrated structure includes: a housing assembly with a guide groove; a drive assembly mounted on the housing assembly; a brewing assembly connected to the drive assembly, having a brewing chamber and capable of reciprocating relative to the drive assembly; a powder scraping assembly mounted on the brewing assembly, having a powder inlet, capable of moving in the guide groove and rotating relative to the brewing assembly; and a push rod liquid inlet assembly mounted on the housing assembly and / or the brewing assembly, capable of reciprocating relative to the brewing assembly in the brewing chamber.

[0005] The above discloses an integrated structure for scraping and feeding coffee grounds in a brewing machine. The guide groove of the housing component provides a stable movement trajectory for the scraping component. Combined with the reciprocating motion of the push rod liquid inlet component within the brewing chamber, this ensures precise and comprehensive removal of waste coffee grounds after brewing. The scraping component can move within the guide groove and rotate relative to the brewing component. This composite motion design allows it to flexibly conform to every corner of the coffee brewing area, preventing residue and thoroughly removing even coffee grounds in narrow gaps. The powder inlet design allows for the quick and precise removal of waste coffee grounds, enabling the introduction of new coffee grounds into the brewing chamber, ensuring the brewing machine can continuously operate for the user. The drive component moves the brewing component up and down, while the brewing component drives the scraping component to rotate, thus achieving the functions of powder collection and brewing.

[0006] In one embodiment, the brewing component has at least three positions relative to the driving component: a first position, a second position, and a third position; the powder scraping component has at least three positions relative to the brewing component: a fourth position, a fifth position, and a sixth position; and the push-rod liquid inlet component has at least two positions relative to the brewing component: a seventh position and an eighth position. When the brewing component is in the first position, the powder scraping component is in the fourth position, and the push-rod liquid inlet component is in the seventh position. The push-rod liquid inlet component abuts against the brewing component, the brewing chamber is open, and the powder scraping component is moved away from the portion of the brewing component that is connected to the driving component. The powder inlet is positioned opposite the brewing chamber. When the brewing component is in the second position, the powder scraper is in the fifth position, and the push rod liquid inlet is in the seventh position. The push rod liquid inlet abuts against the brewing component, the brewing chamber is open, and the powder scraper is located near the part where the brewing component is connected to the drive component. When the brewing component is in the third position, the powder scraper is in the sixth position, and the push rod liquid inlet is in the eighth position. The push rod liquid inlet passes through the brewing chamber, the brewing chamber is closed, and the powder scraper is positioned opposite to the push rod liquid inlet. By utilizing the different positions of the brewing component on the drive component, the brewing machine achieves three functions: powder receiving, brewing, and powder scraping. Firstly, with the brewing component in the first position, the powder scraper in the fourth position, and the push rod liquid inlet in the seventh position, the three work together to create an efficient coffee powder receiving system. At this point, the pusher-operated liquid inlet assembly abuts against the brewing assembly, opening the brewing chamber. The powder scraper assembly moves away from the transmission connection of the brewing assembly, and the powder inlet is precisely aligned with the brewing chamber, ensuring that coffee powder can be smoothly introduced from the upstream storage area into the brewing chamber via the powder scraper assembly, completing the coffee powder filling and preparing for subsequent brewing. Next, after powder filling is complete, the brewing state begins. The brewing assembly switches to the second position, the powder scraper assembly reaches the fifth position, and the pusher-operated liquid inlet assembly remains in the seventh position, continuously abutting against the brewing assembly to keep the brewing chamber open. In this state, the powder scraper assembly is close to the transmission connection of the brewing assembly, cooperating with the heating and pressurizing operations of the brewing head to fully extract the coffee powder within the brewing chamber, ensuring the complete release of coffee flavor and meeting the user's demand for coffee quality. Finally, after brewing is complete, all components enter the powder scraping state: the brewing assembly is in the third position, the powder scraper assembly is in the sixth position, and the pusher-operated liquid inlet assembly switches to the eighth position. At this point, the push rod liquid inlet assembly passes through the brewing chamber to close the brewing chamber, pushing the waste coffee powder out of the brewing chamber. The powder scraper assembly moves and rotates using the guide groove to thoroughly scrape away the waste coffee powder in the brewing chamber, allowing it to be smoothly discharged from the brewing assembly, completing the cleaning and finishing work of one brewing cycle.

[0007] In one embodiment, the coffee grounds scraping assembly includes scraping arms, a scraping housing, a coffee inlet housing, and guide blocks. Multiple scraping arms are disposed on both sides of the brewing assembly. The scraping housing is mounted on each scraping arm, and the coffee inlet housing is mounted on the scraping housing. Multiple guide blocks are also disposed one-to-one on each scraping arm, and each guide block can move within a guide groove, causing the scraping arms to rotate relative to the brewing assembly. The coffee inlet housing has a coffee powder receiving port. By symmetrically distributing multiple scraping arms on both sides of the brewing assembly, the working stability of the scraping arms is increased, enabling rapid and thorough removal of residual coffee grounds from the brewing chamber. The scraping housing ensures the continuity and stability of the scraping action while providing a mounting base for the coffee inlet housing, making the entire coffee grounds scraping assembly structure compact and orderly. The precise alignment of the powder inlet on the powder inlet housing with the brewing chamber ensures that coffee powder is smoothly introduced into the brewing chamber when added, preventing it from falling elsewhere and causing waste, while also ensuring the cleanliness of the brewer's interior. The cooperation between the guide blocks and guide channels is the core of the precise operation of the powder scraping assembly. Multiple guide blocks are correspondingly installed on the powder scraping arm. As it moves within the guide channels, it not only provides a stable trajectory for the scraping arm but also drives the scraping arm to rotate relative to the brewing assembly. This rotational motion allows the scraping arm to reach every corner of the brewing chamber, especially edges and hard-to-reach areas, achieving thorough powder scraping and complete removal of waste coffee powder. Simultaneously, the sliding cooperation between the guide blocks and guide channels reduces friction and resistance during the scraping process, lowering energy consumption, extending the lifespan of the powder scraping assembly, and ensuring efficient and stable operation of the coffee brewer's waste coffee powder handling process, providing users with a convenient and worry-free experience.

[0008] In one embodiment, multiple scraper arms, scraper housings, feed housings, and guide blocks are integrally formed. By integrally forming these components, the scraping and feeding functions are combined into one unit. This ingenious structural design optimizes and upgrades the process of handling waste coffee powder and introducing new coffee powder in the coffee brewing machine. The combined function eliminates the need for separate scraping and feeding components, simplifying the internal layout of the equipment. Furthermore, the integral molding avoids gaps and weak points that can result from splicing or assembling individual components, making the entire scraping assembly a robust whole. This allows it to withstand various forces generated during scraping, including friction from waste coffee powder and the thrust from the push rod feed assembly, preventing deformation or damage. This ensures stable performance of the scraping assembly during long-term use, improving the reliability and lifespan of the coffee brewing machine.

[0009] In one embodiment, the brewing assembly includes a connecting support, a powder receiving container, connecting blocks, and a brewing head. The connecting support is kinetically connected to the drive assembly. The powder receiving container is mounted on the connecting support. Multiple connecting blocks are located on either side of the powder receiving container. The brewing head is mounted on the housing assembly. The connecting support can move the powder receiving container away from or towards the brewing head, embedding the brewing head within the brewing chamber. A powder scraping assembly is mounted on the connecting blocks. A push rod liquid inlet assembly can reciprocate within the powder receiving container, which has the brewing chamber. By connecting the connecting support to the drive assembly, the powder receiving container can move precisely under drive. When the powder receiving container is away from the brewing head, the brewing chamber is open. At this time, the powder scraping assembly can smoothly collect coffee powder through the powder receiving port, introducing it into the brewing chamber. When the coffee grounds container approaches the brewing head and is inserted into the brewing chamber, a sealed brewing space is formed. Combined with the external water supply and heating system, this allows for the extraction and brewing of the coffee grounds, ensuring the full release of flavor compounds. Multiple connecting blocks are located on both sides of the container, providing stable support for the scraper assembly and ensuring its smooth rotation. The reciprocating motion of the pusher-type liquid inlet assembly within the container plays a crucial role at different stages: during dispensing, it helps to distribute the coffee grounds evenly; during brewing, it moderately compacts the coffee grounds, optimizing extraction; and during scraping, it pushes out waste coffee grounds, working in conjunction with the scraper assembly to complete the cleaning process.

[0010] In one embodiment, the push rod liquid inlet assembly includes a push rod device and a fixing device. The fixing device is disposed on the housing assembly, and the push rod device is disposed on the fixing device and / or the brewing assembly. The push rod device can reciprocate within the brewing assembly. By mounting the fixing device on the housing assembly, a stable support base is provided for the push rod liquid inlet assembly, ensuring that the entire push rod liquid inlet assembly remains in a fixed position during operation and avoiding the impact on working accuracy due to shaking or displacement. The push rod device, disposed on the fixing device and / or the brewing assembly, can flexibly reciprocate within the brewing assembly, allowing it to play a multi-functional role in different working stages. During the coffee grounds dispensing stage, the pusher moves to the bottom of the brewing assembly, fully opening the brewing chamber to add as much new coffee grounds as possible, laying the foundation for uniform extraction. During brewing, the pusher applies appropriate pressure, working with the brewing head to compact the coffee grounds and maintain stable pressure within the brewing chamber, ensuring full contact between the coffee grounds and hot water, thus improving extraction efficiency and quality. Once brewing is complete and the process begins, the pusher passes through the brewing chamber to push out waste coffee grounds, working with the scraper to thoroughly remove coffee grounds, ensuring a clean and residue-free brewing chamber.

[0011] In one embodiment, the pusher device includes a drive gear, a pusher, a top cover, a sealing ring, and a control device. The control device is mounted on the housing assembly, the drive gear is mounted on the brewing assembly, and the control device controls the movement of the drive gear. The pusher is driven by the drive gear, the top cover is mounted on the pusher, and the pusher can drive the top cover to reciprocate within the brewing assembly. The sealing ring is mounted on the top cover. By mounting the control device on the housing assembly, the movement of the drive gear is precisely controlled, thereby achieving precise control of the pusher's reciprocating motion. This precise control ensures that the pusher performs the corresponding actions at different working stages—coffee powder collection, brewing, and scraping—meeting the specific needs of each stage of coffee making. The pusher is driven by the drive gear and directly acts on the coffee powder or waste coffee grounds within the brewing assembly. During the coffee grounds collection stage, the pusher engages with the brewing assembly, fully opening the brewing chamber and providing a good foundation for subsequent brewing. During brewing, the pusher applies pressure to optimize the density of the coffee grounds, promoting even hot water penetration and improving extraction. When scraping, the pusher quickly passes through the brewing chamber, pushing the compacted coffee grounds towards the outlet, working in conjunction with the scraper assembly to clean the coffee. The sealing ring on the top cover plays a crucial role in preventing hot water or coffee leakage during brewing, ensuring stable pressure within the brewing chamber, and preventing liquid from corroding the internal structure of the pusher assembly, thus extending the equipment's lifespan. Furthermore, this sealing design meets food hygiene requirements, ensuring the safety and cleanliness of the coffee-making process.

[0012] In one embodiment, the fixing device includes a fixing support and fixing members. The fixing support is disposed on the housing assembly, and there are multiple fixing members disposed on the fixing support. These fixing members abut against the push rod assembly. By placing the fixing support on the housing assembly as the basic structure of the fixing device, the entire fixing device is securely connected to the main structure of the coffee brewing machine. The multiple fixing members on the fixing support abut against the push rod assembly. When the push rod assembly ejects the waste coffee pouch, the coffee pouch, due to brewing and compaction, generates a certain reaction force on the push rod. The multiple fixing members abut against the push rod assembly provide support from multiple points when the push rod bears this reaction force, keeping the push rod in a stable position and preventing it from shaking or shifting due to force. Simultaneously, during the scraping process, the scraping assembly applies a lateral force to the coffee pouch and the push rod to scrape the coffee pouch out of the brewing chamber. Without the support of the fixing members, the push rod could easily shift or even fall under the action of this lateral force. Multiple fasteners, through contact with the push rod, can balance the force applied by the powder scraping assembly, firmly fixing the push rod in its original position and ensuring the smooth operation of the powder scraping process.

[0013] In one embodiment, the drive assembly includes a drive motor, a drive block, and a screw rod. The drive motor is mounted on the housing assembly, the drive block is mounted on the drive motor, and the screw rod is drive-connected to the drive block. By mounting the drive motor on the housing assembly, stable rotational power is provided to the entire drive system. The drive block acts as a transmission hub, converting the rotational motion of the drive motor into a transmission form suitable for the screw rod. The screw rod, drive-connected to the drive block, converts the rotational motion into linear motion, thereby driving the brewing assembly to reciprocate, allowing the brewing assembly to smoothly switch between the first, second, and third positions. This transmission method not only provides sufficient thrust but also achieves precise position control, ensuring that the brewing assembly is accurately positioned at each working position, achieving precise coordination with the powder scraper assembly and the pusher liquid inlet assembly.

[0014] In one embodiment, a grinding assembly is also included, disposed on the housing assembly. The grinding assembly has a powder outlet, and the powder receiving port of the scraper assembly is capable of receiving the material output from the powder outlet. By placing the grinding assembly on the housing assembly, combined with the powder outlet design, the delivery of the ground coffee powder to the receiving port can be precisely controlled, achieving a seamless connection from grinding to receiving. This design ensures that the coffee powder does not scatter or get lost during transport, maintaining the cleanliness of the work area, while also improving the automation and efficiency of the entire coffee making process.

[0015] The second aspect of this application discloses a brewing device, which includes: the aforementioned integrated powder scraping and feeding structure; and a brewing device body, wherein the integrated powder scraping and feeding structure is disposed on the brewing device body.

[0016] The second aspect disclosed above discloses a brewer in which an integrated powder feeding and scraping structure is set on the brewer body. Since the powder receiving and scraping structure is integrally formed, the number and complexity of internal parts of the machine are reduced, and the space occupation and complex connection relationship between multiple independent parts are avoided. This helps to optimize the internal space layout of the machine, making the entire coffee machine smaller, lighter, and easier for users to use and store. Attached Figure Description

[0039] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model 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.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0041] The following describes, with reference to the accompanying drawings, some embodiments of the integrated powder scraping and feeding structure and the brewing device of this utility model.

[0042] Example 1

[0043] like Figures 1 to 15 As shown, this embodiment discloses an integrated structure for scraping and feeding powder, including: a housing assembly 1, which has a guide groove 101; a drive assembly 2, which is disposed on the housing assembly 1; a brewing assembly 3, which is connected to the drive assembly 2 and has a brewing chamber 301, and can reciprocate relative to the drive assembly 2; a powder scraping assembly 4, which is disposed on the brewing assembly 3 and has a powder inlet 401, and can move in the guide groove 101 and rotate relative to the brewing assembly 3; and a push rod liquid inlet assembly 5, which is disposed on the housing assembly 1 and / or the brewing assembly 3, and can reciprocate relative to the brewing assembly 3 in the brewing chamber 301.

[0044] This application discloses an integrated structure for scraping and feeding coffee powder in a brewing machine. The guide groove 101 of the housing assembly 1 provides a stable movement trajectory for the scraping component 4. Combined with the reciprocating motion of the push rod liquid inlet assembly 5 within the brewing chamber 301, this ensures precise and comprehensive removal of waste coffee powder after brewing. The scraping component 4 can move within the guide groove 101 and rotate relative to the brewing assembly 3. This composite motion design allows it to flexibly conform to every corner of the coffee brewing area, preventing residue and thoroughly removing even coffee grounds in narrow gaps. The powder inlet 401 allows for quick and precise removal of waste coffee powder, enabling the introduction of new coffee powder into the brewing chamber 301, ensuring the brewing machine can continuously operate for the user. The drive assembly 2 drives the brewing assembly 3 to move up and down, and the brewing assembly 3 drives the scraping component 4 to rotate, thus achieving the functions of powder collection and brewing.

[0045] like Figures 2 to 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the brewing component 3 has at least a first position, a second position, and a third position relative to the driving component 2; the powder scraping component 4 has at least a fourth position, a fifth position, and a sixth position relative to the brewing component 3; and the push rod liquid inlet component 5 has at least a seventh position and an eighth position relative to the brewing component 3. When the brewing component 3 is in the first position, the powder scraping component 4 is in the fourth position, and the push rod liquid inlet component 5 is in the seventh position. The push rod liquid inlet component 5 abuts against the brewing component 3, the brewing chamber 301 is opened, and the powder scraping component 4 moves away from the brewing component 3 and the driving component. In the transmission connection section, the powder inlet 401 is positioned opposite to the brewing chamber 301. When the brewing component 3 is in the second position, the powder scraper 4 is in the fifth position, and the push rod liquid inlet component 5 is in the seventh position. The push rod liquid inlet component 5 abuts against the brewing component 3, the brewing chamber 301 is open, and the powder scraper 4 is close to the transmission connection between the brewing component 3 and the drive component 2. When the brewing component 3 is in the third position, the powder scraper 4 is in the sixth position, and the push rod liquid inlet component 5 is in the eighth position. The push rod liquid inlet component 5 passes through the brewing chamber 301, the brewing chamber 301 is closed, and the powder scraper 4 is positioned opposite to the push rod liquid inlet component 5. By utilizing the different positions of the brewing component 3 on the drive component 2, the brewing machine achieves three functions: powder receiving, brewing, and powder scraping. First, when the brewing component 3 is in the first position, the powder scraper 4 is in the fourth position, and the push rod liquid inlet component 5 is in the seventh position, the three work together to construct an efficient coffee powder receiving system. At this point, the pusher-operated liquid inlet assembly 5 abuts against the brewing assembly 3, opening the brewing chamber 301. The powder scraper assembly 4 moves away from the transmission connection of the brewing assembly 3, and the powder inlet 401 is precisely aligned with the brewing chamber 301, ensuring that coffee powder can be smoothly introduced from the upstream storage area into the brewing chamber 301 via the powder scraper assembly 4, completing the coffee powder filling and preparing for subsequent brewing. Next, after the powder is filled, the brewing state begins. The brewing assembly 3 switches to the second position, the powder scraper assembly 4 reaches the fifth position, and the pusher-operated liquid inlet assembly 5 remains in the seventh position, continuously abutting against the brewing assembly 3 to keep the brewing chamber 301 open. In this state, the powder scraper assembly 4 is close to the transmission connection of the brewing assembly 3, cooperating with the heating and pressurizing operations of the brewing head to fully extract the coffee powder within the brewing chamber 301, ensuring the complete release of coffee flavor and meeting the user's demand for coffee quality. Finally, after brewing, all components enter the powder scraping state: the brewing assembly 3 is in the third position, the powder scraper assembly 4 is in the sixth position, and the pusher-operated liquid inlet assembly 5 switches to the eighth position. At this time, the push rod liquid inlet assembly 5 passes through the brewing chamber 301 to close the brewing chamber 301, pushes the waste coffee powder out of the brewing chamber 301, and the powder scraper assembly 4 moves and rotates using the guide groove 101 to completely scrape away the waste coffee powder in the brewing chamber 301, so that it can be smoothly discharged from the brewing assembly 3, completing the cleaning and finishing work of one brewing cycle.

[0046] like Figure 5 , Figure 6 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further defines: the powder scraping assembly 4 includes a powder scraping arm 41, a powder scraping housing 42, a powder inlet housing 43, and guide blocks 44. There are multiple powder scraping arms 41, which are disposed on both sides of the brewing assembly 3. The powder scraping housing 42 is disposed on the multiple powder scraping arms 41, and the powder inlet housing 43 is disposed on the powder scraping housing 42. There are multiple guide blocks 44, which are disposed one-to-one with the multiple powder scraping arms 41. The multiple guide blocks 44 can move in the guide groove 101 and drive the multiple powder scraping arms 41 to rotate relative to the brewing assembly 3. The powder inlet housing 43 is provided with a powder inlet 401. By symmetrically distributing the multiple powder scraping arms 41 on both sides of the brewing assembly 3, the working stability of the powder scraping arms 41 is increased, enabling them to quickly and thoroughly scrape away the residual coffee grounds in the brewing chamber 301. The powder scraping housing 42 ensures the continuity and stability of the powder scraping action, while providing an installation base for the powder inlet housing 43, making the entire powder scraping assembly 4 structurally compact and orderly. The powder inlet 401 on the powder inlet housing 43 precisely aligns with the brewing chamber 301, ensuring that coffee powder is smoothly introduced into the brewing chamber 301 when added, preventing coffee powder from falling to other places, causing waste, and also making it difficult to ensure the cleanliness of the inside of the brewing machine. The cooperation between the guide block 44 and the guide groove 101 is the core of the precise operation of the powder scraping assembly 4. Multiple guide blocks 44 are correspondingly installed on the powder scraping arm 41. When moving within the guide groove 101, they not only provide a stable movement trajectory for the powder scraping arm 41, but also drive the powder scraping arm 41 to rotate relative to the brewing assembly 3. This rotational movement allows the powder scraping arm 41 to fit into every corner of the brewing chamber 301, especially the edges and dead corner areas, achieving powder scraping without dead corners and thoroughly removing waste coffee powder. At the same time, the sliding cooperation between the guide block 44 and the guide groove 101 reduces friction and resistance during the powder scraping process, reduces energy consumption, extends the service life of the powder scraping assembly 4, and ensures efficient and stable operation of the coffee brewing machine's waste coffee powder handling process, bringing users a convenient and worry-free user experience.

[0047] like Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines that: multiple scraper arms 41, scraper housing 42, powder inlet housing 43, and multiple guide blocks 44 are integrally formed. By integrally forming multiple scraper arms 41, scraper housing 42, powder inlet housing 43, and multiple guide blocks 44, the scraping and powder inlet functions are combined into one unit. Through the ingenious structural design, the processing flow of waste coffee powder and the introduction of new coffee powder in the coffee brewing machine is optimized and upgraded. The combination of the two functions avoids the space required for separate scraper and powder inlet components, simplifying the internal layout of the equipment. At the same time, the integral molding avoids the connection gaps and weak points caused by splicing or assembling individual components, making the entire scraper assembly a sturdy whole. This can withstand various forces generated during the scraping process, including the friction with waste coffee powder and the thrust of the push rod liquid inlet assembly 5, etc., and is not prone to deformation or damage, ensuring that the scraper assembly 4 maintains stable performance during long-term use, improving the reliability and service life of the coffee brewing machine.

[0048] like Figure 3 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the brewing assembly 3 includes a connecting support 31, a powder receiving container 32, connecting blocks 33, and a brewing head 34. The connecting support 31 is connected to the drive assembly 2. The powder receiving container 32 is disposed on the connecting support 31. There are multiple connecting blocks 33, which are distributed on both sides of the powder receiving container 32. The brewing head 34 is disposed on the housing assembly 1. The connecting support 31 can drive the powder receiving container 32 away from or near the brewing head 34 and embed the brewing head 34 in the brewing cavity 301. The powder scraping assembly 4 is disposed on the multiple connecting blocks 33. The push rod liquid inlet assembly 5 can reciprocate within the powder receiving container 32. The powder receiving container 32 is provided with a brewing cavity 301. By connecting the connecting support 31 to the drive assembly 2, the powder receiving container 32 can move precisely under the drive. When the coffee powder container 32 is away from the brewing head 34, the brewing chamber 301 is open. At this time, the coffee powder scraper 4 can smoothly collect coffee powder through the powder inlet 401, introducing the coffee powder into the brewing chamber 301. When the coffee powder container 32 approaches the brewing head 34 and is placed inside the brewing chamber 301, a closed brewing space is formed. With the help of the external water supply and heating system, the coffee powder is extracted and brewed, ensuring the full release of coffee flavor substances. Multiple connecting blocks 33 are distributed on both sides of the coffee powder container 32, providing stable support for the coffee powder scraper 4 and ensuring that the coffee powder scraper 4 can rotate and scrape the coffee powder smoothly. The reciprocating motion of the push rod liquid inlet assembly 5 in the coffee powder container 32 plays a key role in different stages: when collecting coffee powder, it can help distribute the coffee powder evenly; during brewing, it can moderately compact the coffee powder to optimize the extraction effect; during scraping, it can push out waste coffee powder and work with the coffee powder scraper 4 to complete the cleaning work.

[0049] like Figure 2 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further defines: the push rod liquid inlet assembly 5 includes a push rod device 51 and a fixing device 52. The fixing device 52 is disposed on the housing assembly 1, and the push rod device 51 is disposed on the fixing device 52 and / or the brewing assembly 3. The push rod device 51 can reciprocate within the brewing assembly 3. By installing the fixing device 52 on the housing assembly 1, a stable support foundation is provided for the push rod liquid inlet assembly 51, ensuring that the entire push rod liquid inlet assembly 5 remains in a fixed position during operation, avoiding the impact on working accuracy due to shaking or displacement. The push rod device 51 is disposed on the fixing device 52 and / or the brewing assembly 3, and can flexibly reciprocate within the brewing assembly 3. This movement mode allows it to play multiple roles in different working stages. During the coffee powder collection stage, the pusher device 51 can move to the bottom of the brewing assembly 3, fully opening the brewing chamber 301 to add as much new coffee powder as possible, laying the foundation for subsequent uniform extraction. During the brewing process, the pusher device 51 can apply appropriate pressure, working with the brewing head 34 to compact the coffee powder and maintain stable pressure within the brewing chamber 301, ensuring full contact between the coffee powder and hot water, thus improving coffee extraction efficiency and quality. When the brewing process is complete and the process enters the powder scraping stage, the pusher device 51 passes through the brewing chamber 301 to push out the waste coffee powder from the brewing chamber 301, working with the powder scraping assembly 4 to thoroughly remove the coffee grounds, ensuring a clean and residue-free brewing chamber.

[0050] like Figure 10 and Figure 11As shown, in addition to the features of the above embodiments, this embodiment further defines: the pusher device 51 includes a drive gear 511, a pusher 512, a top cover 513, a sealing ring 514, and a control device. The control device is mounted on the housing assembly 1, the drive gear 511 is mounted on the brewing assembly 3, and the control device controls the movement of the drive gear 511. The pusher 512 is drivenly connected to the drive gear 511, the top cover 513 is mounted on the pusher 512, and the pusher 512 can drive the top cover 513 to reciprocate within the brewing assembly 3. The sealing ring 514 is mounted on the top cover 513. By mounting the control device on the housing assembly 1, the movement process of the drive gear 511 is precisely controlled, thereby achieving precise control of the reciprocating movement of the pusher 512. This precise control ensures that the pusher can perform corresponding actions in different working stages, such as receiving coffee powder, brewing, and scraping coffee powder, meeting the specific needs of each stage of coffee making. The pusher 512 is drivenly connected to the drive gear 511 and directly acts on the coffee powder or waste coffee grounds within the brewing assembly 3. During the coffee grounds collection stage, the push rod 512 abuts against the brewing assembly 3, fully opening the brewing chamber 301 and providing a good foundation for subsequent brewing. During brewing, the push rod 512 can apply pressure to optimize the density of the coffee grounds, promote even penetration of hot water, and improve extraction efficiency. When scraping the grounds, the push rod 512 quickly passes through the brewing chamber 301, pushing the compacted coffee grounds towards the outlet, working in conjunction with the scraping assembly to complete the cleaning process. The sealing ring 514 on the top cover 513 plays a crucial sealing role, preventing leakage of hot water or coffee liquid during brewing, ensuring stable pressure within the brewing chamber 301, and preventing liquid from corroding the internal structure of the push rod assembly 51, thus extending the equipment's lifespan. Furthermore, this sealing design also meets food hygiene requirements, ensuring the safety and cleanliness of the coffee making process.

[0051] like Figure 10 and Figure 13As shown, in addition to the features of the above embodiments, this embodiment further defines: the fixing device 52 includes a fixing support 521 and fixing members 522. The fixing support 521 is disposed on the housing assembly 1, and there are multiple fixing members 522 disposed on the fixing support 521. The multiple fixing members 522 can abut against the push rod device 51. By disposing of the fixing support 521 on the housing assembly 1 as the basic structure of the fixing device, the entire fixing device is stably connected to the main structure of the coffee brewing machine. The multiple fixing members 522 disposed on the fixing support 521 abut against the push rod device 51. When the push rod device 51 pushes out the waste coffee pouch, the coffee pouch, due to brewing and compaction, will generate a certain reaction force on the push rod. The multiple fixing members 522 abut against the push rod device 51, which can provide support from multiple points when the push rod 512 bears this reaction force, so that the push rod maintains a stable position and prevents it from shaking or shifting due to force. Simultaneously, during the scraping process, the scraper assembly 4 applies a lateral force to the coffee puck and pusher to scrape the coffee puck out of the brewing chamber 301. Without the support of the fixing members 522, the pusher 512 could easily shift or even fall off under this lateral force. Multiple fixing members 522, through contact with the pusher 512, balance the force applied by the scraper assembly, firmly fixing the pusher 512 in place and ensuring the smooth operation of the scraping process.

[0052] like Figure 5 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further defines: a drive assembly 2 consisting of a drive motor 21, a drive block 22, and a screw rod 23. The drive motor 21 is mounted on the housing assembly 1, the drive block 22 is mounted on the drive motor 21, and the screw rod 23 is driveably connected to the drive block 22. By mounting the drive motor 21 on the housing assembly 1, stable rotational power is provided for the entire drive system. The drive block 22 acts as a transmission hub, converting the rotational motion of the drive motor 1 into a transmission form suitable for the screw rod 23. The screw rod 23 is driveably connected to the drive block 2, converting the rotational motion into linear motion, thereby driving the brewing assembly 3 to achieve reciprocating motion, allowing the brewing assembly 3 to smoothly switch between the first, second, and third positions. This transmission method not only provides sufficient thrust but also achieves precise position control, ensuring that the brewing assembly 3 is accurately positioned at each working position, achieving precise cooperation with the powder scraper assembly 4 and the push rod liquid inlet assembly 5.

[0053] like Figures 2 to 4As shown, in addition to the features of the above embodiments, this embodiment further includes a grinding component 6, which is disposed on the housing component 1. The grinding component 6 has a powder outlet, and the powder receiving port 401 of the powder scraper component 4 can receive the material output from the powder outlet. By placing the grinding component 6 on the housing component 1 and combining it with the design of the powder outlet, the delivery of the ground coffee powder to the powder receiving port 401 can be precisely controlled, achieving a seamless connection from grinding to receiving. This design ensures that the coffee powder will not scatter or be lost during the transmission process, keeping the working area clean, and also improving the automation and efficiency of the entire coffee making process.

[0054] Example 2

[0055] like Figures 1 to 15 As shown, this embodiment discloses a brewing device, including: the above-mentioned integrated powder scraping and feeding structure; and a brewing device body, wherein the integrated powder scraping and feeding structure is disposed on the brewing device body.

[0056] The second aspect of this application discloses a brewer in which an integrated powder feeding and scraping structure is set on the brewer body. Since the powder receiving and scraping structure is integrally formed, the number and complexity of internal parts of the machine are reduced, avoiding space occupation and complex connection relationships between multiple independent parts. This helps to optimize the internal space layout of the machine, making the entire coffee machine smaller, lighter, and easier for users to use and store.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
