Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and in particular to a brewing device for coffee machines. Background Art

[0002] A coffee machine is an electrical device specifically used to make coffee. It can brew, extract, steam or mix coffee powder and water through different techniques and mechanisms to produce coffee drinks of various flavors.

[0003] Generally speaking, in the technical solution of a fully automatic coffee machine, it becomes a series of automated procedures such as grinding, filling powder, pressing powder, brewing, and cleaning. The user only needs to operate with one button to get a cup of fragrant coffee; this kind of coffee machine is especially suitable for home and office use, and thus has been widely used.

[0004] In the technical solution of the aforementioned fully automatic coffee machine, the process of brewing coffee generally includes: the brewing cylinder assembly receives coffee powder, the brewing cylinder assembly moves to the position of the coffee brewing head assembly to compact and brew the coffee powder, the brewing cylinder assembly separates from the coffee brewing head assembly, the brewing cylinder assembly pushes out the coffee grounds, scrapes off the coffee grounds, and the brewing cylinder assembly resets and moves to the position to receive the coffee powder.

[0005] For example, a Chinese invention patent with publication number CN109222657B discloses a fully automatic freshly ground coffee machine, which includes a cabinet, a cabinet door installed on the front of the cabinet, and a coffee bean box, a powder box, a grinder, an extractor, a water heater, and a water storage tank arranged in the cabinet, the coffee bean box is connected to the grinder for conveying coffee beans to the grinder for grinding the coffee beans into powder, the extractor is respectively connected to the grinder and the water storage tank for extracting the ground coffee powder into coffee juice, the water heater is connected to the water storage tank for obtaining a hot water source for brewing coffee, and a control panel and a pickup window arranged on the cabinet door; in addition, it also includes an automatic cup dropper, a stirrer, an automatic cover dropper, a robot, and an automatic cover pressing device arranged in the cabinet and controlled by the control panel.

[0006] However, in the various technical solutions of fully automatic coffee machines disclosed in the prior art, generally speaking, there are still technical problems such as difficult disassembly and assembly of the brewing device and inconvenient cleaning. Specifically, in some existing technical solutions of fully automatic coffee machines, the brewing core component and the brewing head are fixed inside the machine and cannot be taken out and cleaned separately, so that after long-term operation, the internal pipes are blocked due to failure to timely clean the coffee or coffee powder residues remaining in the brewing core component, which will directly affect the final taste of the coffee; and, because the user cannot effectively clean the inside of the brewing core component, the coffee powder residues remaining in the brewing cavity will become moldy, which will not only affect the taste of the coffee, but also pollute the brewing cavity.

[0025] Please also read Figure 1 to Figure 2 The present invention provides a brewing device comprising: a support 1, a driving mechanism 2, a brewing tube component 3, a piston component 4 and a brewing head component 5; the driving mechanism 2 is arranged on the adjacent side of the support 1, the brewing tube component 3 is movably arranged in the support 1, and the piston component 4 is movably arranged in the brewing tube component 3; the brewing head component 5 is arranged in the support 1, and the brewing head component 5 is matched with the brewing tube component 3; The brewing tube component 3 comprises a guide sliding part 301, a linkage sliding rod 302 and a brewing tube body 303. The guide sliding part 301 and the linkage sliding rod 302 are both connected to the brewing tube body 303. The driving mechanism 2 is drivingly connected to the linkage sliding rod 302. The support 1 is provided with a first support groove 101, a second support groove 102 and a support body 103, and the first support groove 101 and the second support groove 102 are both provided on the support body 103; the linkage slide rod 302 is movably connected with the first support groove 101, and the guide sliding part 301 is movably connected with the second support groove 102.

[0026] Specifically, when the brewing device of the present invention is in working process, the driving mechanism 2 is pre-powered connected with an external power device, such as a motor. When the external power device drives the driving mechanism 2, the driving mechanism 2 can drive the linkage slide bar 302 provided in the brewing tube body 303 to slide along the first support slide groove 101; then, the linkage slide bar 302 drives the lower part of the brewing tube body 303, so that the guide sliding part 301 provided on the side of the brewing tube body 303 can slide along the second support slide groove 102; thus, the brewing tube body 303 can realize swinging, rising, resetting and other actions in the support body 103.

[0027] Furthermore, the brewing device of the present invention is further provided with a reset connecting rod 6 and a reset supporting part 7, wherein the reset connecting rod 6 is provided on the brewing tube body 303, and the reset connecting rod 6 is rotatably connected to the brewing tube body 303; the reset connecting rod 6 is provided with a connecting rod body 601 and an abutting part 602; one end of the connecting rod body 601 is provided with the abutting part 602, and the other end of the connecting rod body 601 is movably connected to the lower part of the piston component 4. The reset supporting part 7 is provided on the support body 103, and the reset supporting part 7 is provided with a supporting body 701 and an abutting surface 702; the abutting surface 702 is arc-shaped, and the abutting part 602 is connected to or separated from the abutting surface 702 by abutment.

[0028] Specifically, in a specific embodiment, the movable connection between the reset connecting rod 6 and the brewing tube body 303 can be a hinge, and the hinge is located between the connection between the reset connecting rod 6 and the reset supporting part 7 and the connection between the reset connecting rod 6 and the piston part 4. One end of the reset connecting rod 6 can be movably abutted with the reset supporting part 7 or release the connection relationship of mutual contact with the reset supporting part 7. The two sides of the reset supporting part 7 are respectively connected to the support body 103, and the movable contact connection between the reset supporting part 7 and the reset connecting rod 6 can be set as a curved surface structure. Thereby, the aforementioned abutting part 602 can be abutted and connected with the abutting surface 702 or the abutting part 602 can be temporarily separated from the abutting surface 702 in a preset position.

[0029] Thus, when the linkage slide rod 302 is driven by the driving mechanism 2 to slide along the first support slide groove 101, the reset link 6 can be driven by driving the brewing tube body 303; and the abutment portion 602 provided on the reset link 6 can abut and slide along the arc surface of the abutment surface 702 provided on the reset support portion 7, and at the same time, the reset link 6 moves together with the piston component 4 to the bottom of the brewing tube body 303.

[0030] Specifically, when the driving mechanism 2 drives the linkage slide bar 302 to move, the linkage slide bar 302 can move along the guidance of the first support slide groove 101, thereby driving the brewing tube body 303 to move, and then the guide sliding part 301 set on the side of the brewing tube body 303 can move along the guidance of the second support slide groove 102, and the brewing tube body 303 can be swung in the support body 103 to align with the brewing head component 5 in turn, and at the same time drive the piston component 4 and the reset connecting rod 6 upward to release the contact connection with the reset supporting seat 7, the brewing tube body 303 is matched with the brewing head component 5 so that the piston component 4 set in the cavity of the brewing tube body 303 cooperates with the brewing head component 5 to press the powder cake, and after the powder cake is pressed, hot water enters the brewing tube body 303 through the water inlet and completes the process of extracting coffee liquid, so that the coffee liquid flows out from its water outlet.

[0031] For further information, please refer to Figure 2 and Figure 3 A limited top block component 8 is also arranged in the support body 103, and the limited top block component 8 has a top block swinging part 801 and a top block return torsion spring 802; the top block swinging part 801 is movably arranged on the support body 103, and the top block return torsion spring 802 connects the support body 103 and the top block swinging part 802 respectively.

[0032] Specifically, when the brewing barrel main body 303 is driven by the linkage slide rod 302 and guided to be matched and connected with the brewing head component 5, the brewing barrel main body 303 is gradually sleeved on the outside of the brewing head component 5, so that the piston component 4 arranged in the cavity of the brewing barrel main body 303 can gradually approach the brewing head component 5 in its cavity; before this moving process, when the brewing barrel main body 303 completes receiving the powder and starts to swing, the lower part of the piston component 4 will push the limiting top block component 8 and push it away; thereby, the powder such as coffee powder placed in the brewing barrel component 3 can be pressed into a powder cake in the cavity of the brewing barrel main body 303 when the piston component 4 moves close to the brewing head component 5.

[0033] Specifically, when the external power mechanism such as the motor reverses the power, the driving mechanism 2 reversely drives the linkage slide bar 302 to reset the components. During the reset process, the limit top block component 8 will abut the lower part of the piston component 4, thereby preventing the piston component 4 from moving downward, while the brewing tube component 3 and the like will continue to move downward. At this time, the powder cake in the brewing tube component 2 will move forward relative to the inner cavity of the brewing tube body 303 due to the tight limit of the piston component 4, and then the powder cake and other residues will be pushed out by the piston component 4. Until the brewing tube component 3 moves downward to the swing reset point, at this time, the linkage slide bar 302 is continuously driven by the driving mechanism 2 to swing and reset the brewing tube component 3. While it swings, the piston component 4 also swings with it, so that the lower part of the piston component 4 is separated from the top block swinging part 801, and the limit of the top block swinging part 801 on the piston component 4 is released. At the same time, the external slag sheet and other structures will block the slag cake pushed out of the brewing tube body 303 by the piston component 4, so that the slag cake is pushed away from the outlet of the brewing tube body 303. After the brewing tube body 303 is swung into place, the slag cake has been completely pushed away, and at the same time, the abutment portion 602 provided by the reset connecting rod 6 and the abutment surface 702 provided by the reset supporting portion 7 re-establish abutment connection. Therefore, during the reset process, the piston component 4 can be reset to the initial position in the brewing tube body 303 under the drive of the reset connecting rod 6. Thus, each component is restored to the initial state.

[0034] Therefore, a brewing device of the present invention can utilize the sliding motion pair composed of the linkage slide bar 302 and the first support slide groove 10, and the sliding motion pair composed of the guide slide part 301 and the second support slide groove 102 to realize the entire process of brewing coffee or other beverages, such as the swing adjustment, movement and rise of the brewing cylinder body 301, and the pressing of the powder cake, ejection of the powder cake, retraction and reset of the piston part 4. The overall structure of this brewing device is simple and easy to achieve; moreover, the main body of the entire brewing device can be separated from the main body of equipment such as a coffee machine, thereby making it easy to disassemble and clean. Therefore, it can be known that a brewing device of the present invention discloses a brewing device for a coffee machine or other beverage machine, which can solve the technical problems of the existing coffee machine or other beverage machine, such as the complex structure, inconvenient disassembly and assembly, and the difficulty in cleaning and maintaining the brewing unit.

[0035] For further information, see Figure 4In a specific embodiment, the first support chute 101 has a first guide chute 101a and a second guide chute 101b; the first guide chute 101a and the second guide chute 101b are both arranged on the side of the support body 103, and the first guide chute 101a is connected to the second guide chute 101b. The first guide chute 101a and the second guide chute 101b can be a blind groove structure or a through groove structure; thus, it can be defined that the end point of the first guide chute 101a is point A, the connection point between the first guide chute 101a and the second guide chute 101b is point B, and the end point of the second guide chute 101b is point C.

[0036] For details, please refer to Figure 4 The second support slide groove 102 has a swing guide groove 102a and a first support guide groove 102b; the swing guide groove 102a and the first support guide groove 102b are both arranged on the side of the support 1, and the swing guide groove 102a is connected with the first support guide groove 102b. The swing guide groove 102a and the first support guide groove 102b can be a blind groove structure or a through groove structure; thus, it can be defined that one end point of the swing guide groove 102a is point D, and one end point of the first support guide groove 102b is point E. Thus, if Figure 5 As shown, when the linkage slide bar 302 is in the initial position, at this time, the end of the linkage slide bar 302 is located at point A in the first support slide groove 101, and one end of the guide sliding part 301 is located at point D in the swing guide groove 102a; one end of the reset connecting rod 6 is movably abutted against the surface of the reset supporting part 7, that is, the abutting part 602 is abutted and connected with the abutting surface 702; at this time, the brewing tube component 3 is in the initial locking position, in which the brewing tube body 303 can accept materials such as coffee powder input by an external grinding device, and can also directly accept powder input by a user from the outside.

[0037] Next, see Figure 6When the positive power of an external power device such as an electric motor is input to the driving mechanism 2, the driving mechanism 2 drives the linkage slide bar 302 to move; at this time, in the first support slide groove 101, the linkage slide bar 302 moves from point A to point B, and in the second support slide groove 102, one end of the guide sliding part 301 takes point D as the force fulcrum, and the body of the guide sliding part 301 swings along the guidance of the swing guide groove 102a; in this process , the linkage slide bar 302 cooperates with the guide sliding part 301 to drive the brewing tube body 303, specifically: the linkage slide bar 302 drives the lower part of the brewing tube body 303, and at the same time, the contact point between the guide sliding part 301 and point D is the swing fulcrum of the brewing tube body 303, so that it swings and slides through the stroke of the swing guide groove 102a; thereby, the brewing tube body 303 can be swung until its open end is aligned with the bottom of the brewing head component 5. At this time, the end of the reset connecting rod 6, that is, the abutment part 602 leaves the surface of the reset support part 7, that is, the surface of the abutment surface 702, that is, the two are no longer in active abutment. The piston component 4 is still maintained at the lower part of the brewing tube body 303, and the limit top block component 8 is abutted and pushed open by the lower part of the piston component 4; that is, in this stage, the limit top block component 8 will not limit the piston component 4.

[0038] For further information, please refer to Figure 7 ; At this time, the driving mechanism 2 continues to drive the linkage slide bar 302 to make it continue to slide in the first support slot 101. During this process, in the first support slot 101, the linkage slide bar 302 moves from point B to point C; at the same time, in the second support slot 102, the guide sliding part 301 moves from point D to point E. Thus, the linkage slide bar 302 can drive the brewing cylinder body 303 under the drive of the driving mechanism 2, and when it moves, the guide sliding part 301 always moves forward along the limit of the first support guide slot 102b. Thus, the linkage slide bar 302 can drive the lower part of the brewing cylinder body 303 to move close to and sleeve the brewing head component 5, and make the piston component 4 arranged in the cavity of the brewing cylinder body 303 and the brewing head component 5 align and move close. Afterwards, the brewing tube body 303 is gradually sleeved on the outside of the brewing head component 5, and the piston component 4 gradually approaches the brewing head component 5 and starts to press the powder cake; until the powder is compacted to a preset resistance, and the external motor or other power device stops outputting power; at this time, the piston component 4 stops moving.

[0039] Specifically, after the powder cake is pressed, hot water introduced from the outside enters the cavity of the brewing tube body 303, and after the action of extracting coffee liquid in the cavity of the brewing tube body 303 is completed, the coffee liquid flows out of the cavity of the brewing tube body 303.

[0040] Specifically, after the brewing cylinder body 303 moves upward to the preset position, the lower part of the piston component 4 rises to above the top block swinging part 801, and the top block reset torsion spring 802 can use elastic force to reset the top block swinging part 801; at this time, the upper part of the top block swinging part 801 is located below the piston component 4.

[0041] Next, please continue reading Figure 8 After the coffee extraction is completed, the external power device such as the motor can output power in the reverse direction, thereby causing the driving mechanism 2 to be driven in the reverse direction; at this time, the upper part of the top block swinging part 801 will abut against the lower part of the piston component 4 to restrict its retreat, but the top block swinging part 801 will not affect the moving action of the brewing tube component 3, that is, at this time the brewing tube body 303 can be retreated while the piston component 4 does not move, that is, the piston component 4 continues to move forward relative to the brewing tube component 3 and pushes out the ground cake in the brewing tube component 3, that is, the ground material formed after the powder cake completes the extraction of coffee liquid.

[0042] After that, please continue to see Fig. 9 , when the driving mechanism 2 continues to drive the linkage slide bar 302 to move, so that: the linkage slide bar 302 returns from point C to point B in the first support slot 101, and the guide slide part 301 returns from point E to point D in the second support slot 102; in this stage, when the guide slide part 301 descends to point D of the second support slot 102, the brewing cylinder body 303 reaches the downward stop point, and it no longer descends, but can swing back with point D as the support point, at this time, the linkage slide bar 302 is exactly at point B. When the brewing cylinder body 303 is driven to swing back to the aforementioned position, it can first swing to make the lower part of the piston component 4 disengage from the top block swing part 801 due to following the swing of the brewing cylinder body 303, so as to release the limiting contact with the piston component 4.

[0043] Furthermore, if the external motor or other power mechanism continues to reverse, so that the linkage slide bar 302 starts to slide from point B to point A, the brewing tube body 303 performs a reset swinging action, so that the aforementioned slag cake is blocked by the external slag sheet or similar components at the upper outlet of the cavity of the brewing tube body 303 and is pushed away from the cavity outlet of the brewing tube body 303; for example, Fig. 9The scraper component 9 is arranged at the adjacent side of the brewing head component 5 and can be movably connected to the end of the brewing cylinder body 303.

[0044] After the slag cake is completely pushed away and falls, one end of the reset link 6 is again in active contact with the surface of the reset support 7. Fig. 9 , the lower position of the abutting surface 702 provided on the reset support part 7 is defined as point I, and the higher position thereof is defined as point H. It can be known that at this time, the abutting portion 602 provided on the reset link 6 is exactly located at point I. Until the linkage slide bar 302 is reset to point A again, the abutting portion 602 can also slide along the abutting surface 702 to reset from point I to point H; during this action stroke of the reset link 6; the piston component 4 can be pulled by the reset link 6 and reset along the downward direction of the brewing tube component 3. At this time, all components are reset to the initial state, that is, the brewing process of a beverage such as coffee is completed, and the brewing tube body 303 can continue to receive external coffee powder and other materials.
