Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a brewing component for coffee machines. Background Technology

[0002] In modern life, coffee machines have become a common tool for many coffee lovers to make delicious coffee. Among them, the brewing mechanism, as the core part of the coffee machine, directly affects the brewing quality of the coffee.

[0003] For example, patent number CN115137210B provides a coffee brewing mechanism, whose brewing component includes a brewing head, a swinging component, and a first drive motor. The first drive motor is connected to the brewing head via the swinging component. The brewing head is provided with a first slider, which is slidably connected to a first guide groove. The swinging component is provided with a powder scraper. The swinging component is constructed to include: a swinging bracket, a first transmission gear, and a first transmission mechanism. The swinging bracket and the first transmission gear are rotatably connected to the body around a first rotation center. The first transmission gear is connected to the first drive motor and is connected to the brewing head via the first transmission mechanism. Its powder pushing component includes a powder pushing rod, a second threaded gear, and a second drive motor. One end of the powder pushing rod extends into the brewing chamber. The second threaded gear is threadedly connected to the powder pushing rod. The second drive motor is connected to the second threaded gear and is used to drive the powder pushing rod to move axially along the brewing chamber via the second threaded gear, so as to compact the coffee powder in the brewing chamber or push the coffee grounds in the brewing chamber out from the second opening.

[0004] In the aforementioned structure, the coffee maker employs a design where the powder-dispensing component and the brewing component are driven separately. This separate drive means the coffee machine needs multiple independent drive units, which not only increases the hardware cost but also makes the internal structure more complex. The complex drive system requires more space for layout, leading to a larger overall size and hindering miniaturization and portability. From a maintenance perspective, multiple drive units mean more components are prone to failure; if a drive component fails, the difficulty and cost of repair will increase accordingly. Furthermore, precise coordination between multiple drive units is required to ensure the smooth operation of the coffee brewing process, which places high demands on the control logic of the drive system and increases the difficulty of developing the control system.

[0023] (III) Beneficial Effects

[0024] The brewing component for a coffee machine provided by this utility model has the following advantages compared with the prior art:

[0025] 1) The brewing structure of this coffee machine uses a drive mechanism to oscillate the brewing hopper and a linkage mechanism to compact the coffee powder and eject the coffee puck. This eliminates the need for multiple independent drive units, effectively simplifying the internal structure and reducing hardware costs. The simplified structure reduces space occupancy, making the overall size of the coffee machine easier to control and facilitating miniaturization and portability, meeting user needs for different usage scenarios. The reduced number of drive units also reduces the number of potentially faulty parts, lowering the difficulty and cost of repair when a component fails, thus improving the product's ease of maintenance and cost-effectiveness. The single drive mechanism combined with the linkage mechanism reduces the requirements for the drive system's control logic, eliminating the need for complex coordination between multiple drive units, reducing the difficulty of control system development, and improving the stability and reliability of the coffee brewing process.

[0026] 2) The linkage mechanism adopts a top rod base, which has a simple structure and ingenious design. Through the push wall of a specific shape on the top rod base, the top rod of the brewing pot moves up and down relative to the brewing pot during the swinging process of the brewing pot. This ingeniously completes the functions of coffee powder compaction and coffee grounds ejection. The operation is smooth and can ensure the degree of coffee powder compaction and the effect of coffee grounds ejection during the brewing process, which helps to improve the quality of coffee brewing.

[0027] 3) The coffee grounds scraper and scraper spring are installed. When the coffee grounds are pushed out of the brewing pot, the scraper can extend to block the coffee grounds and make them fall into the feeding inclined guide wall for feeding. This realizes the automation and convenience of coffee grounds cleaning and improves the user experience. Attached Figure Description

[0049] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0050] See Figures 1 to 14 This utility model provides a brewing component for a coffee machine, including a brewing core component, which includes a brewing support 1, a brewing head 2, a brewing hopper 3, a brewing hopper top rod 4, a drive mechanism, and a linkage mechanism.

[0051] See Figures 4 to 6The brewing support 1 includes two parallel and spaced-apart support plates, multiple connecting rods connecting the two support plates, and a base plate for supporting the linkage mechanism. A brewing head 2 is fixed to the upper inner side of the brewing support 1. A brewing bucket 3 is located inside the brewing support 1 and can be oscillatingly mounted below the brewing head 2. The brewing bucket 3 can be molded with the brewing head 2 to brew coffee. The brewing bucket 3 is connected to the brewing head 2 via a drive mechanism. The drive mechanism drives the brewing bucket 3 to oscillate. Under the drive of the drive mechanism, the brewing bucket 3 and the brewing bucket top rod 4 can oscillate between the outer and inner sides of the brewing support 1. The drive mechanism includes a swing rod 61 rotatably mounted on the side of the brewing head 2 and a drive connecting rod 62 hinged between the swing rod 61 and the brewing bucket 3. One end of the drive connecting rod 62 is hinged to the swing rod 61, and the other end of the drive connecting rod 62 is hinged to the brewing bucket 3. The brewing support 1 is provided with a guide groove 101 for guiding the brewing bucket 3, and the brewing bucket 3 can move along the guide groove 101. When the drive mechanism drives the brewing bucket 3 to swing to the outside of the brewing support 1, the brewing bucket 3 is in the receiving state of receiving coffee powder; when the drive mechanism drives the brewing bucket 3 to swing to close with the brewing head 2, the brewing bucket 3 is in the brewing state of brewing coffee.

[0052] See Figures 4 to 6 The brewing bucket top rod 4 is height-adjustable and can be installed inside the brewing chamber 301 of the brewing bucket 3. The brewing head 2 is equipped with a pressure head that is compatible with the brewing chamber 301. The upper part of the brewing chamber 301 has an opening, and the pressure head can be placed into the brewing chamber 301 after the mold is closed. The linkage mechanism is installed at the bottom of the brewing bucket top rod 4; during the process of the drive mechanism driving the brewing bucket 3 to swing, the linkage mechanism links the brewing bucket top rod 4 to raise and lower it relative to the brewing bucket 3, thereby realizing the functions of tamping coffee powder and ejecting coffee grounds.

[0053] Unlike existing designs where the coffee grounds pushing and brewing components are driven separately, this coffee machine's brewing structure uses a drive mechanism to oscillate the brewing hopper and a linkage mechanism to tamp the coffee grounds and eject the coffee puck. This eliminates the need for multiple independent drive units, effectively simplifying the internal structure and reducing hardware costs. The simplified structure reduces space occupancy, making the overall size of the coffee machine easier to control and facilitating miniaturization and portability, meeting user needs in various scenarios. The reduced number of drive units also reduces the number of potentially faulty parts, lowering the difficulty and cost of repairs in case of component failure, thus improving the product's ease of maintenance and cost-effectiveness. The single drive mechanism combined with the linkage mechanism reduces the requirements for the drive system's control logic, eliminating the need for complex coordination between multiple drive units, reducing the difficulty of control system development, and improving the stability and reliability of the coffee brewing process.

[0054] In some embodiments, such as Figures 4 to 7As shown, the linkage mechanism includes a top rod base 5 rotatably mounted at the bottom of the brewing support 1, which corresponds to the brewing pot top rod 4. The brewing pot top rod 4 includes a disc-shaped portion inside the brewing chamber 301 and a rod portion outside the brewing pot 3. A push wall 501 is provided at the upper end of the top rod base 5, and the rod portion of the brewing pot top rod 4 can be placed on the push wall 501. During the process of the driving mechanism driving the brewing pot 3 to swing, the lower end of the brewing pot top rod 4 can slide along the push wall 501, thereby causing the brewing pot top rod 4 to rise and fall relative to the brewing pot 3, thus realizing the functions of coffee powder compaction and coffee puck ejection. This structure, through the push wall of a specific shape on the top rod base in the linkage mechanism, realizes the rise and fall of the brewing pot top rod relative to the brewing pot during the swinging of the brewing pot, thus cleverly completing the functions of coffee powder compaction and coffee puck ejection. The operation is smooth and can ensure the degree of coffee powder compaction and coffee puck ejection during the brewing process, which helps to improve the quality of coffee brewing.

[0055] In some embodiments, such as Figures 4 to 7 and Figure 11 As shown, the push wall 501 has a shape that is high in the middle and low at both ends. The push wall 501 includes a first inclined push wall 502 located on the outer side and a second inclined push wall 503 located on the inner side. The first inclined push wall 502 and the second inclined push wall 503 are smoothly connected. The first inclined push wall 502 is configured to cause the top rod 4 of the brewing pot 3 to rise relative to the brewing pot 3 when it swings inward (towards the brewing support 1), thereby compacting the coffee powder in the brewing chamber 301. After the coffee is received, the brewing bucket 3 swings towards the inside of the brewing support 1. During the swing, the brewing bucket top rod 4 slides along the first inclined push wall 502. The first inclined push wall 502 has a structure that is lower on the outside and higher on the inside, which makes the brewing bucket top rod 4 move closer to the brewing head 2, thereby pushing the coffee powder in the brewing chamber 301 toward the brewing head 2 and finally cooperating with the brewing head 2 to compact the coffee powder into a coffee cake, so as to facilitate subsequent brewing. Then the brewing bucket top rod 4 slides along the second inclined push wall 503. The second inclined push wall 503 has a structure that is higher on the outside and lower on the inside, which makes the brewing bucket top rod 4 descend a certain distance relative to the brewing head 2, so as to facilitate subsequent brewing and also provide an upward stroke for ejecting the coffee cake.

[0056] The second inclined push wall 503 is configured to cause the brewing bucket top rod 4 to rise relative to the brewing bucket 3 when the brewing bucket 3 swings outward (towards the outside of the brewing support 1), thereby pushing out the coffee cake in the brewing chamber 301. After brewing, the brewing bucket 3 swings outwards towards the outside of the brewing support 1. During the swing, the brewing bucket top rod 4 slides along the second inclined push wall 503. The second inclined push wall 503 causes the brewing bucket top rod 4 to move towards the brewing head 2, and it also descends relative to the brewing head 2 when the brewing bucket 3 swings, thereby pushing out the coffee cake from the brewing chamber 301 for easy removal of the coffee cake. Then, the brewing bucket top rod 4 slides along the first inclined push wall 502 and descends for easy subsequent feeding.

[0057] In some embodiments, such as Figure 5 , Figure 12 and Figure 13 As shown, a top rod spring 7 is installed between the brewing pot 3 and the brewing pot top rod 4. The top rod spring 7 always causes the brewing pot top rod 4 to have a downward movement tendency relative to the brewing pot 3. For ease of manufacturing, the brewing pot 3 adopts a split structure, comprising a brewing pot body and a brewing pot base that are fixed to each other. When the brewing pot 3 swings to the outside of the brewing support 1 (in the receiving state), the brewing pot top rod 4 disengages from the top rod base 5. At this time, under the action of the top rod spring 7, the brewing pot top rod 4 is positioned at the lowest end of the brewing chamber 301 for easy receiving. A spring limiting seat 41 is threaded onto the brewing pot top rod 4; the top rod spring 7 is sleeved on the brewing pot top rod 4, with one end of the top rod spring 7 abutting against the spring limiting seat 41 and the other end abutting against the brewing pot 3. In this structure, a spring is installed between the brewing hopper and the brewing hopper top rod, so that the brewing hopper top rod can automatically return to the bottom of the brewing chamber when the brewing hopper swings to the outside, preparing for the subsequent receiving of materials in the brewing chamber; at the same time, the top rod spring, together with the spring limit seat, can adjust the preload of the top rod spring, which is convenient for adjustment.

[0058] In some embodiments, such as Figures 5 to 7As shown, one end of the push rod base 5 is hinged to the brewing support 1, and a torsion spring is installed between the push rod base 5 and the brewing support 1. An arc-shaped baffle 504 is provided on the side of the push rod base 5, and the outer end of the push rod base 5 is pointed. The arc-shaped baffle 504 extends inward from the pointed end to facilitate the brewing bucket push rod 4 pressing against the push rod base 5 and causing it to swing. When the brewing bucket 3 swings from the receiving state towards the inside of the brewing support 1, the brewing bucket 3 drives the brewing bucket push rod 4 to move towards the push rod base 5. Then, the brewing bucket push rod 4 presses against the arc-shaped baffle 504, causing the push rod base 5 to swing to avoid the brewing bucket push rod 4. When the brewing bucket push rod 4 rises to a certain height, the torsion spring causes the push rod base 5 to return to its original position. At this time, the brewing bucket push rod 4 abuts against the first inclined push wall 502 and slides along the first inclined push wall 502, thereby compressing the coffee powder. The lower end of the brewing pot top rod 4 is fitted with a locking piece 42, which is engaged in the groove of the brewing pot top rod 4. During use, the locking piece 42 presses against the arc-shaped baffle 504, which can prevent the brewing pot top rod 4 from wearing out and extend its service life. In addition, the locking piece 42 is easy to disassemble and replace.

[0059] In some embodiments, such as Figure 5 , Figure 6 as well as Figures 8 to 11 As shown, a scraper 8 is vertically mounted on one side of the outer wall of the brewing head 2. A scraper spring 9 is installed between the scraper 8 and the brewing head 2, and the scraper spring 9 always causes the scraper 8 to tend to move downwards. The scraper 8 can rest against the upper end of the brewing hopper 3. The side of the brewing hopper 3 away from the scraper 8 is provided with a feeding inclined guide wall 302. After brewing is completed, when the brewing hopper 3 swings towards the outside of the brewing support 1, the brewing hopper push rod 4 slides along the second inclined push wall 503, and the brewing hopper push rod 4 pushes out the coffee cake. At the same time, the brewing hopper 3 descends relative to the brewing head 2. At this time, under the action of the scraper spring 9, the scraper 8 extends to prevent the coffee cake from following the movement of the brewing hopper 3. As the brewing hopper 3 continues to swing, the coffee cake falls into the feeding inclined guide wall 302 for feeding. This structure features a coffee grounds scraper that can be raised and lowered on one side of the brewing head's outer wall, equipped with a scraper spring. When the brewing bucket swings outward and pushes out coffee grounds with the top rod, the scraper extends to block the grounds, causing them to fall into the inclined guide wall for discharge. This automates and simplifies coffee grounds cleaning, enhancing the user experience.

[0060] In some embodiments, such as Figures 4 to 6 as well as Figure 8As shown, a drive shaft 63 is mounted on the brewing head 2, and a first gear 64 is installed at one end of the drive shaft 63. A clearance groove 621 is provided on the drive connecting rod 62 to avoid the drive shaft 63. In the normal state (brewing position), the clearance groove 621 ensures that the axis of the drive shaft 63 is close to the line connecting the two hinge points of the drive connecting rod 62, giving the drive mechanism a certain self-locking capability and preventing the components from moving under gravity, resulting in better performance. A drive shaft bracket 65 is mounted on the drive shaft 63, and the drive shaft bracket 65 is fitted onto the outside of the drive shaft 63. A rocker arm 61 is located on both sides of the drive shaft bracket 65, and the rocker arm 61 and the drive shaft bracket 65 are an integral structure. This structure, with rocker arms and drive connecting rods on both sides of the brewing head 2, makes the driving of the brewing hopper 3 more stable. During operation, the first gear 64 drives the drive shaft 63 to rotate, which in turn drives the drive shaft bracket 65 to rotate, causing the two swing arms 61 to swing. The swing arms 61 then drive the brewing hopper 3 to swing via the drive connecting rod 62. In this structure, the drive shaft passes through the brewing head and is fitted with the first gear. The drive connecting rod has a clearance groove to keep the axis of the drive shaft close to the line connecting its hinge point. This, combined with the drive shaft bracket and the swing arms on both sides, results in a compact drive structure with high transmission efficiency and good stability.

[0061] In some embodiments, such as Figures 4 to 6 As shown, the guide groove 101 is L-shaped and arranged on both sides of the brewing support 1. There are two guide grooves 101 on each side, arranged vertically, providing good guiding effect and stability. The brewing pot 3 is provided with a first guide post 303 that matches the guide groove 101, and the first guide post 303 is placed inside the guide groove 101. The brewing support 1 is provided with an arc-shaped guide groove 102, and the swing arm 61 is provided with a second guide post 611 that matches the arc-shaped guide groove 102. One end of the drive connecting rod 62 is hinged to the swing arm 61 through the second guide post 611. The L-shaped guide groove cooperates with the first guide post on the brewing pot, and the arc-shaped guide groove cooperates with the second guide post on the swing arm, precisely guiding the movement of the brewing pot and the swing arm, ensuring the stability and accuracy of the brewing structure during the swing process, and ensuring the smooth progress of the coffee brewing process.

[0062] In some embodiments, such as Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 14As shown, a water inlet pipe 10 is provided on one side of the brewing head 2, and a water inlet connecting pipe 11 is provided on the brewing pot 3, which can communicate with the water inlet pipe 10. When the brewing head 2 and the brewing pot 3 are closed, the water inlet pipe 10 is inserted into the water inlet connecting pipe 11 to achieve communication. The water inlet connecting pipe 11 is connected to the bottom of the brewing chamber 301, and a coffee outlet pipe 12 connected to the brewing chamber 301 is provided on the other side of the brewing head 2. To ensure airtightness, rubber rings are fitted on both the brewing head 2 and the brewing pot top rod 4. To improve the coffee flavor, coffee filters are installed on both the brewing head 2 and the brewing pot top rod 4. During brewing and extraction, water enters the bottom of the brewing chamber 301 through the water inlet pipe 10 and the water inlet connecting pipe 11, and then the water passes through the brewing pot top rod 4 from the bottom of the brewing chamber 301 to extract the coffee cake. The extracted coffee liquid flows out through the coffee outlet pipe 12. The brewing pot top rod 4 is equipped with a through hole for water supply; this structure and water channel design are conducive to the reasonable distribution of water flow and the smooth flow of coffee liquid during the coffee brewing process, further improving the coffee brewing quality.

[0063] In some embodiments, such as Figures 1 to 4 As shown, it also includes a main support 13. The brewing support 1 is detachably installed inside the main support 13. This structure allows the brewing core component to be detachably connected to the main support 13, facilitating modular assembly and maintenance. A handle 14 is swivelly installed at the top of the brewing support 1. The handle 14 is U-shaped and one end is hinged to one side of the brewing support 1. The other side of the brewing support 1 has a movable groove for the handle 14 to rotate. Under the limitation of the movable groove, the handle 14 can rest against the side wall of the movable groove, thereby lifting the entire brewing core component through the handle 14, which is convenient for lifting and moving.

[0064] like Figures 1 to 4 As shown, one end of the handle 14 is symmetrically provided with limiting protrusions 141, which are positioned close to the movable groove. The main support 13 has a receiving groove 131 for accommodating the brewing core component. The inlet of the receiving groove 131 has a limiting slot 132 that matches the limiting protrusion 141. When assembling the brewing core component, the component is pushed into the receiving groove 131 through the inlet. Then, the handle 14 is rotated to allow the limiting protrusion 141 to fall into the limiting slot 132, preventing the brewing core component from detaching from the receiving groove 131, thus facilitating assembly and disassembly.

[0065] like Figures 1 to 4As shown, a coffee powder channel 15 is installed on the main support 13. When the brewing hopper 3 is in the receiving state, the brewing chamber 301 corresponds to the coffee powder channel 15, and coffee powder can be added into the brewing chamber 301 through the coffee powder channel 15. A drive motor 16 is installed on one side of the main support 13, and a second gear 17 is installed on the drive motor 16. The second gear 17 can mesh with the first gear 64. When the brewing core components are assembled in place, the second gear 17 meshes with the first gear 64; during driving, the drive motor 16 works, the drive motor 16 drives the second gear 17 to rotate, and the second gear 17 drives the first gear 64 to rotate.

[0066] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0067] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
