Description

Technical Field

[0001] This application relates to the field of coffee machine technology, and more particularly to a brewing device and a coffee machine. Background Technology

[0002] After prolonged use and multiple brewing sessions, especially under intensive continuous operation, coffee machines often accumulate a significant amount of coffee grounds and residue inside the brewer. While existing semi-detachable brewer designs allow for cleaning of the brewing chamber, the brewing head remains fixed to the frame, making it difficult to remove or clean. This design makes cleaning the brewing head extremely inconvenient and prone to accumulating fine coffee grounds and residue. These residues not only affect subsequent brewing results, altering the taste, but may even disrupt the normal operation of the coffee machine, increasing maintenance complexity. Summary of the Invention

[0003] In view of the above-mentioned technical problems existing in the prior art, this application provides a brewing device and a coffee machine, which can realize the complete detachment of the brewing head assembly from the frame assembly, that is, realize the quick removal of the brewing head assembly, which is conducive to thorough cleaning of the brewing head assembly, resulting in better and more stable coffee extraction effect.

[0004] This application provides a brewing device, including: An actuation assembly includes a drive member and a frame assembly connected to the drive member. The drive member is used to drive the frame assembly to perform lifting and lowering movements. The frame assembly has a mounting slot with an open side and a first groove extending through its upper and lower ends. A brewing head assembly includes a sliding boss and a second groove. The second groove extends through the upper and lower ends of the brewing head assembly. The sliding boss slides into the mounting groove along the opening of the mounting groove to limit the displacement of the brewing head assembly in a first direction. After the sliding boss is installed in the mounting groove, the first groove and the second groove are correspondingly arranged. A dispensing connector, which passes through the first and second tanks, is used to limit the displacement of the brewing head assembly in a second direction; wherein the first and second directions are perpendicular to each other. This structure allows the brewing head assembly to be completely detached from the frame assembly, enabling rapid removal and thorough cleaning, resulting in better and more stable coffee extraction.

[0005] In some embodiments, a limiting buckle is formed on the outer wall of the dispensing connector, and a limiting groove adapted to the limiting buckle is formed on the wall of the second tank. The limiting buckle is installed in the second tank along the limiting groove. In this way, the dispensing connector can be aligned and inserted into the second tank through the cooperation of the limiting buckle and the limiting groove, ensuring accurate installation between the dispensing connector and the brewing head assembly.

[0006] In some embodiments, the limiting buckle has an installation position opposite to the limiting groove and a locking position offset from the limiting groove. After being installed in the second groove, the limiting buckle is rotatably offset from the limiting groove to confine the dispensing connector within the brewing head assembly. Thus, the limiting buckle ensures the connection stability between the dispensing connector and the brewing head assembly, allowing the dispensing connector to be stably placed within the brewing head assembly and the holder assembly.

[0007] In some embodiments, the frame assembly further has a U-shaped groove communicating with the mounting slot, and the brewing head assembly further includes a connecting portion connected to the lower part of the sliding boss, the connecting portion being mounted on the frame assembly via the open end of the U-shaped groove. Thus, the installation stability of the frame assembly and the brewing head assembly can be further increased through the cooperation of the connecting portion and the U-shaped groove.

[0008] In some embodiments, the frame assembly includes a detachably connected movable frame and a fixed frame, the movable frame being connected to the drive member, and the mounting slot being formed on the fixed frame. This structure is simple and increases the flexibility of the frame assembly in terms of assembly and disassembly.

[0009] In some embodiments, the brewing head assembly has a limiting block inside. The limiting block is used to abut against the limiting buckle after the limiting buckle rotates to a preset angle, thereby limiting the rotation angle of the limiting buckle. In this way, the installation stability between the brewing head assembly and the liquid dispensing connector can be further ensured by limiting the rotation angle of the limiting buckle by the limiting block.

[0010] In some embodiments, the brewing head assembly further includes a detachably connected base and a brewing head body, wherein the sliding boss and the second groove are both formed on the base, and the brewing head body is sleeved on the base. The above-mentioned structure, in which the brewing head body is sleeved on the base, is simple in design and ensures the installation stability of the brewing head body and the base.

[0011] In some embodiments, the brewing head assembly further includes a filter screen and a sealing ring. The filter screen is installed at the lower opening of the brewing head body, and the sealing ring is fitted over the lower part of the brewing head body. Thus, the filter screen ensures that the coffee liquid is filtered before entering the dispensing inlet, and the sealing ring ensures a tight seal between the brewing head body and the inner wall of the brewing cup, making the brewing head assembly structurally sound and reliable.

[0012] In some embodiments, the base may have an elastic mounting arm with a protrusion, and the brewing head body has a slot. The elastic mounting arm deforms under the action of the inner wall of the brewing head body until the protrusion engages with the slot. Thus, the engagement of the protrusion on the elastic mounting arm and the slot on the brewing head body allows the brewing head body to be stably fitted onto the base, maintaining a relatively stable position after installation and preventing arbitrary rotation.

[0013] This application provides a coffee machine including the brewing device described in any of the above embodiments. The above structure allows for the complete detachment of the brewing head assembly from the frame assembly, enabling quick removal of the brewing head assembly, facilitating thorough cleaning, and resulting in better and more stable coffee extraction.

[0014] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: In this application, the sliding boss of the brewing head assembly slides into the mounting groove along the opening of the mounting groove. At this time, the first groove and the second groove are correspondingly arranged. The liquid outlet connector passes through the first groove and the second groove, which can limit the displacement of the brewing head assembly in the first direction and the second direction. When it is necessary to disassemble the brewing head assembly, the liquid outlet connector can be moved away from the first groove and the second groove, and then the sliding boss can be moved away from the mounting groove. In this way, the brewing head assembly can be completely removed from the frame assembly, which realizes the quick removal of the brewing head assembly, which is conducive to thorough cleaning of the brewing head assembly, resulting in better and more stable coffee extraction effect.

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] This application provides a brewing device. For example... Figures 1 to 4 As shown, the brewing device includes an actuation component, a brewing head assembly 3, and a dispensing connector 4. The actuation component includes a drive element 1 and a frame assembly 2 connected to the drive element 1. The drive element 1 drives the frame assembly 2 to move vertically. The frame assembly 2 has a mounting groove 21 with an open side and a first groove 22 extending through its upper and lower ends. The brewing head assembly 3 includes a sliding boss 31 and a second groove 32 extending through its upper and lower ends. The sliding boss 31 slides into the mounting groove 21 along its open side to limit the displacement of the brewing head assembly 3 in a first direction. After the sliding boss 31 is inserted into the mounting groove 21, the first groove 22 and the second groove 32 are correspondingly positioned. The dispensing connector 4 passes through the first groove 22 and the second groove 32, and is used at least to limit the displacement of the brewing head assembly 3 in a second direction; wherein the first direction and the second direction are perpendicular.

[0020] like Figure 1 As shown, the aforementioned drive component 1 can be connected to the frame assembly 2 via the transmission assembly 5. The transmission assembly 5 includes a screw 51 connected to the output shaft of the drive component 1. Under the drive of the drive component 1, the screw 51 can rotatably drive the frame assembly 2 to perform lifting and lowering movements.

[0021] like Figure 1 As shown, the screw 51 can be fitted with an abutment block 52. The abutment blocks 52 are distributed on opposite sides of the frame assembly 2. The two abutment blocks 52 cooperate to limit the movement range of the frame assembly 2, so that the frame assembly 2 can move stably between the two abutment blocks 52.

[0022] Below the aforementioned brewing head assembly 3 is a brewing cup 6. The brewing head assembly 3 descends into the brewing cup 6, compacting the powdered ingredients within the cup and ensuring optimal brewing results. A push rod 7 is located at the bottom of the brewing cup 6, movable within it. This push rod 7 moves the powder residue formed during brewing upwards until it is discharged from the cup.

[0023] The length direction of the first groove 22 is perpendicular to the direction in which the sliding boss 31 of the brewing head assembly 3 is installed into the mounting groove 21. Here, the first direction refers to the length direction of the first groove 22 (i.e.,...). Figure 2 The vertical direction is the first direction, and the second direction is the installation direction of the sliding boss 31 (i.e., the vertical direction). Figure 2 (Horizontal direction in the middle).

[0024] After the sliding boss 31 is installed into the mounting groove 21, the center line of the first tank 22 and the center line of the second tank 32 are collinear. The liquid outlet connector 4 can be sequentially inserted into the first tank 22 and the second tank 32 to be installed into the frame assembly 2 and the brewing head assembly 3.

[0025] This application allows the sliding boss 31 of the brewing head assembly 3 to slide into the mounting groove 21 through the opening of the mounting groove 21. At this time, the first groove 22 and the second groove 32 are correspondingly arranged. The liquid outlet connector 4 passes through the first groove 22 and the second groove 32, which can limit the displacement of the brewing head assembly 3 in the first direction and the second direction. When it is necessary to disassemble the brewing head assembly 3, the liquid outlet connector 4 can be moved away from the first groove 22 and the second groove 32, and then the sliding boss 31 can be moved away from the mounting groove 21. In this way, the brewing head assembly 3 can be completely removed from the frame assembly 2, which realizes the quick removal of the brewing head assembly 3, which is conducive to thorough cleaning of the brewing head assembly 3, and makes the coffee extraction effect better and more stable.

[0026] In some embodiments, such as Figures 1 to 4 As shown, a limiting buckle 41 is formed on the outer wall of the liquid outlet connector 4, and a limiting groove 33 adapted to the limiting buckle 41 is formed on the groove wall of the second tank 32. The limiting buckle 41 is installed in the second tank 32 along the limiting groove 33.

[0027] In this way, the liquid outlet connector 4 can be aligned and inserted into the second tank 32 by the cooperation of the limiting buckle 41 and the limiting groove 33, thus ensuring the precise installation between the liquid outlet connector 4 and the brewing head assembly 3.

[0028] There can be multiple buckles and limiting slots 33, and each buckle and limiting slot 33 is set in a one-to-one correspondence.

[0029] The aforementioned outlet connector 4 can be understood as being used to discharge the coffee liquid formed after brewing. A water inlet is formed at the bottom of the brewing cup 6. Both the water inlet and the outlet chamber of the outlet connector 4 are connected to the brewing chamber of the brewing cup 6. The brewing liquid entering through the inlet brews the coffee powder in the brewing chamber, and after brewing, it is directly pushed towards the outlet connector 4 under pressure, achieving a bottom-up dispensing method. This increases the mixing time between the coffee powder and the brewing liquid, ensuring extraction efficiency and further improving the taste.

[0030] The upper end of the above-mentioned liquid outlet connector 4 can be connected to a liquid outlet pipe, which is a flexible tube that can directly discharge the prepared coffee liquid.

[0031] In some embodiments, such as Figures 1 to 4 As shown, the limiting buckle 41 has an installation position opposite to the limiting groove 33 and a locking position that is misaligned with the limiting groove 33. After being installed in the second groove 32, the limiting buckle 41 rotates and is misaligned with the limiting groove 33 to confine the liquid outlet connector 4 within the brewing head assembly 3. Figure 2 The limiting buckle 41 shown is in a locked position that is misaligned with the limiting groove 33. At this time, the liquid outlet connector 4 is confined within the brewing head assembly 3.

[0032] In this way, the connection stability between the liquid outlet connector 4 and the brewing head assembly 3 can be ensured by the limiting buckle 41, so that the liquid outlet connector 4 can be stably placed in the brewing head assembly 3 and the frame assembly 2.

[0033] After the aforementioned limiting buckle 41 is inserted into the second groove 32 along the limiting groove 33, it can be disengaged from the limiting groove 33, so that the liquid outlet connector 4 can rotate as a whole within the brewing head assembly 3.

[0034] In some embodiments, such as Figures 1 to 4 As shown, the frame assembly 2 also has a U-shaped groove 23 that communicates with the mounting groove 21, and the brewing head assembly 3 also includes a connecting part 34 connected to the lower part of the sliding boss 31. The connecting part 34 is mounted on the frame assembly 2 via the open end of the U-shaped groove 23.

[0035] In this way, the installation stability of the frame assembly 2 and the brewing head assembly 3 can be further increased by the cooperation of the connecting part 34 and the U-shaped groove 23.

[0036] The outer contour dimension of the connecting part 34 is smaller than the outer contour dimension of the sliding boss 31. After the brewing head assembly 3 is installed on the frame assembly 2, the lower surface of the sliding boss 31 abuts against the bottom of the mounting groove 21 so as to support the brewing head assembly 3 through the mounting groove 21.

[0037] The sliding boss 31 and the connecting part 34 can be integrally formed.

[0038] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the frame assembly 2 includes a detachably connected movable frame 24 and a fixed frame 25. The movable frame 24 is connected to the drive component 1, and the mounting groove 21 is formed on the fixed frame 25. The above structure is simple and increases the flexibility of the frame assembly 2 in terms of assembly and disassembly.

[0039] The movable frame 24 and the fixed frame 25 may be provided with connection holes respectively. Connectors are sequentially inserted through the connection holes on the movable frame 24 and the fixed frame 25 so as to stably connect the movable frame 24 and the fixed frame 25 through the connectors.

[0040] In some embodiments, the brewing head assembly 3 is provided with a limiting block (not shown in the figure) inside. The limiting block is used to abut against the limiting buckle 41 after the limiting buckle 41 rotates to a preset angle, so as to limit the rotation angle of the limiting buckle 41.

[0041] In this way, the rotation angle of the limiting buckle 41 can be limited by the limiting block, which further ensures the installation stability between the brewing head assembly 3 and the liquid outlet connector 4.

[0042] The aforementioned limit blocks and limit buckles 41 are designed to correspond one-to-one.

[0043] In some embodiments, such as Figures 1 to 4 As shown, the brewing head assembly 3 also includes a detachably connected base 35 and a brewing head body 36. The sliding boss 31 and the second groove 32 are both formed on the base 35, and the brewing head body 36 is sleeved on the base 35.

[0044] The above-mentioned design of the brewing head body 36 being sleeved outside the base 35 is simple and can ensure the installation stability of the brewing head body 36 and the base 35.

[0045] The brewing head body 36 can be constructed in a cylindrical shape and is sleeved outside the base 35. The outer wall of the base 35 can be engaged with the brewing head body 36.

[0046] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the brewing head assembly 3 also includes a filter screen 37 and a sealing ring 38. The filter screen 37 is installed at the lower opening of the brewing head body 36, and the sealing ring 38 is sleeved on the lower part of the brewing head body 36.

[0047] In this way, the coffee liquid can be filtered through the filter screen 37 before entering the liquid outlet 4, and the sealing ring 38 can ensure the sealing between the inner wall of the brewing head body 36 and the brewing cup 6, making the brewing head assembly 3 structurally reasonable and reliable.

[0048] The lower part of the brewing head body 36 may have a groove, and part of the sealing ring 38 may be embedded in the groove to stably install the sealing ring 38.

[0049] In some embodiments, such as Figure 3 and Figure 4 As shown, the seat 35 may have an elastic mounting arm 39, the elastic mounting arm 39 is provided with a protrusion, and the brewing head body 36 is provided with a slot 310. The elastic mounting arm 39 deforms under the action of the inner wall of the brewing head body 36 until the protrusion is inserted into the slot 310.

[0050] In this way, the protrusion on the elastic mounting arm 39 and the slot 310 on the brewing head body 36 can be used to stably fit the brewing head body 36 onto the base 35, and the two maintain a relatively stable positional relationship after installation and will not rotate arbitrarily.

[0051] During installation, the aforementioned elastic mounting arm 39 will be subjected to the pressure of the inner wall of the brewing head body 36, thereby moving towards the second groove 32. After the elastic mounting arm 39 moves to the slot 310, it moves away from the second groove 32, so that the protrusion is inserted into the slot 310, thereby ensuring that the brewing head body 36 can be stably sleeved on the base 35.

[0052] The working process of the brewing device is described below: After the brewing cup 6 has finished receiving the coffee powder, the drive component 1 drives the transmission component 5 to work. The transmission component 5 drives the brewing head component 3 to move downward through the movable bracket and the fixed bracket. The brewing head component 3 enters the brewing chamber of the brewing cup 6. The brewing head component 3 continues to move to compact the coffee powder in the brewing cup 6. Then, water is continuously supplied to the brewing chamber of the brewing cup 6 through the water inlet. The coffee liquid formed by the mixture of water and coffee powder is brewed through the liquid outlet 4 in the brewing head component 3. Then, the brewing head assembly 3 moves upward to complete its reset. After a long period of coffee brewing, powder residue remains in the brewing head body 36, filter screen 37, sealing ring 38, etc. At this time, the liquid outlet connector 4 can be moved away from the first tank 22 and the second tank 32, and then the sliding boss 31 can be moved away from the mounting groove 21. In this way, the brewing head assembly 3 can be completely removed from the frame assembly 2, realizing the quick removal of the brewing head assembly 3 and facilitating thorough cleaning of the brewing head assembly 3.

[0053] This application provides a coffee machine. The coffee machine includes the brewing device of any of the above embodiments.

[0054] The coffee machine using the above-mentioned brewing device slides the sliding boss 31 of the brewing head assembly 3 into the mounting groove 21 through the opening of the mounting groove 21. At this time, the first groove 22 and the second groove 32 are correspondingly arranged. The liquid outlet 4 passes through the first groove 22 and the second groove 32, which can limit the displacement of the brewing head assembly 3 in the first direction and the second direction. When it is necessary to disassemble the brewing head assembly 3, the liquid outlet 4 can be moved away from the first groove 22 and the second groove 32, and then the sliding boss 31 can be moved away from the mounting groove 21. In this way, the brewing head assembly 3 can be completely removed from the frame assembly 2, realizing the quick removal of the brewing head assembly 3, which is conducive to thorough cleaning of the brewing head assembly 3, resulting in better and more stable coffee extraction effect.

[0055] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its scope and spirit, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
