Description

Technical Field

[0001] This utility model belongs to the field of capsule extraction technology, and in particular relates to an automatic capsule brewing machine. Background Technology

[0002] A capsule-based extraction machine is an extraction device that uses high-pressure, rapid heating of water to extract the corresponding juice from the contents of a container. It is suitable for processing containers (capsules) containing ingredients, which, upon interaction with the liquid introduced into the capsule (such as hot, pressurized water), produce a beverage or edible juice. The capsule is a frustum-shaped ring, which can be filled with ingredients such as coffee powder, tea leaves, concentrated liquid beverages, or the like, and is sealed by a foil-like tear-off cap welded or pressed onto the annular edge extending radially from the sidewall of the ring. A common example of an extraction machine is the capsule coffee machine.

[0003] For example, Chinese utility model patent application document CN109215234A discloses a freshly made beverage vending machine, including a cabinet, a first cabinet door and a second cabinet door. The cabinet is divided from top to bottom into a first chamber, a second chamber for brewing beverages and a third chamber for storing water and waste. The first chamber is equipped with a capsule storage and vending device for storing and selling beverage capsules and a capsule guide device located below the capsule storage and vending device. The first cabinet door is used to close the first chamber and is provided with a retrieval port. The second cabinet door is used to close the second chamber and is provided with a waste disposal port. In the freshly made beverage vending machine, the capsule storage and vending device includes a control unit and a base fixed to the inner wall of the cabinet. The base has several positioning holes evenly arranged, and each positioning hole has a capsule receiving tube that matches the positioning hole. The capsule receiving tube is used to stack beverage capsules, with the bottom beverage capsule hanging below the base. The bottom of the positioning hole extends out of the lower surface of the base and has a first notch. The bottom edge of the positioning hole has a first baffle for supporting the beverage capsule. The first baffle extends toward the center of the positioning hole. Several capsule dispensing mechanisms, each corresponding to a capsule receiving tube, are fixedly arranged on the lower surface of the base for dropping beverage capsules. The capsule dispensing mechanisms pass through the first notch, and each capsule dispensing mechanism is connected to the control unit. In a freshly made beverage vending machine, the capsule dispensing mechanism includes an electromagnet fixedly mounted on the lower surface of the base and connected to a control unit, a guide plate fixedly connected to the iron core of the electromagnet, a fixed post fixedly mounted on the base, and a lever sleeved on the fixed post for dispensing beverage capsules. The guide plate has a guide post at its front end, and the lever has an elongated hole. The guide post is located in the elongated hole and reciprocates within the hole, causing the lever to rotate reciprocally around the fixed post. In the same vending machine, the lever includes a rod body, a first lever head, and a second lever head. The rod body is sleeved on the fixed post, and the first and second lever heads are fixedly connected to the rod body. The first and second lever heads are offset vertically and parallel, forming a first angle between them. The electromagnet drives the lever to rotate reciprocally to dispensing beverage capsules and allows the first or second lever head to support the lowest beverage capsule.

[0004] In the aforementioned patent document, the coffee capsule is positioned with its opening facing upwards and its bottom facing downwards within the capsule container. To achieve coffee extraction, a through-hole needs to be provided at the bottom of the capsule. However, when the coffee capsule is positioned with its bottom facing downwards, some coffee powder may scatter due to the impact force during its descent.

[0005] To address the aforementioned technical deficiencies, those skilled in the art have developed a capsule coffee machine with a milk-frothing function, similar to the Chinese utility model patent disclosed in authorization announcement number CN209360411U. This machine features a capsule dropping device, which uses a telescopic drive assembly to move corresponding stops to control capsule storage and automatic dropping. Specifically, before capsule storage, the first stop closest to the capsule outlet extends to support the capsule, while a second stop retracts to allow the capsule to automatically drop onto the first stop. After all capsules are placed in the guide channel, the second stop extends to block the capsules above it, ensuring that only the capsules between the first and second stops fall, thus completing the pre-storage. When retrieving a capsule from the storage compartment, the first stop retracts, causing the capsule on it to fall from the capsule outlet due to its own weight. The first stop then extends again to support the capsule about to fall. After the first stop extends again, the second stop retracts, and the remaining capsules fall onto the first stop. The second stop then extends again to support the capsules on it. The above process constitutes one work cycle. Repeating this cycle enables automatic capsule feeding. The capsule dropping device connects to the extraction device; simply setting a program ensures that the various telescopic drive components in the control mechanism execute their actions sequentially within the work cycle, thus automatically feeding capsules to the extraction device and automating coffee brewing. Therefore, capsule coffee machines with milk frothing functions can automatically feed capsules to the extraction process, offering a high degree of automation and quick, convenient operation. Simultaneously, they can heat beverages or create milk foam, allowing for the mixing and blending of beverages or milk foam with coffee to create aesthetically pleasing and delicious specialty coffees.

[0006] In the aforementioned patent's technical solution, the capsule is in a horizontal position during the coffee extraction process. However, when capsule coffee is extracted in a horizontal position, the coffee liquid will be at the bottom of the horizontal position, making it impossible to extract the coffee in the capsule coffee more thoroughly.

[0019] Furthermore, the water supply device is located inside the cabinet, and the water supply device includes a heating mechanism and a water pump; the water pump is connected to the heating mechanism and the puncture needle tube.

[0020] Furthermore, the upright plate is a sheet metal part installed inside the cabinet, and the side of the upright plate is bent to form a bent part, which is riveted to the inner side wall of the cabinet; the storage channel includes two symmetrically arranged slots, each slot including a bottom plate, a limiting plate and a side plate, and the limiting plate has clearances at both ends.

[0021] The capsule-type automatic brewing machine provided in this embodiment of the present invention has at least the following technical effects:

[0022] 1. When capsules, such as capsule coffee and capsule tea, are stored in the storage channel, the annular part of the capsule opening is limited in the limiting groove, so that the opening of the capsule faces the upright plate and the capsule is stored in the storage channel in a flat state. When the capsule is conveyed downward, it will not cause coffee powder or other substances to scatter from the extraction hole.

[0023] 2. When capsule extraction is needed, the receiving sleeve is driven to the bottom of the storage channel by the translation device. The telescopic support releases the bottom capsule, causing it to flip downwards under gravity, falling bottom-down into the collar, with the capsule opening edge supported by the collar. The translation device then drives the capsule into the guide groove of the seat, and the pressing mechanism presses down, puncturing the capsule's sealing film with the needle. The water supply device injects hot water into the capsule, completing the coffee extraction. The extracted liquid flows from the bottom into the cup in the concave cavity. After extraction, the receiving sleeve is rotated 180° by the rotation drive, causing the capsule to fall from the receiving sleeve. This completes the fully automatic coffee extraction. Because the capsule is bottom-down during extraction, extraction is more thorough. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0039] In one embodiment of the capsule-type automatic brewing machine of this utility model, please refer to... Figures 1 to 8Specifically, the capsule-type automatic brewing machine of this embodiment can be used for capsule-type fixed brewing and extraction, such as coffee, tea, and fixed beverages. Taking capsule coffee as an example, this embodiment specifically includes a cabinet 100, a material rack 200, a translation device 300, a receiving device 400, and a brewing device 500.

[0040] Specifically, refer to Figures 2 to 4 The shelf 200 includes a vertical plate 210, which is vertically installed within the cabinet 100. The vertical plate 210 has vertically extending storage channels 220 for storing coffee capsules. Limiting grooves 221 are provided on both sides of the storage channels 220 to limit the edges of the coffee capsules, ensuring the openings of the capsules face inwards towards the storage channels 220. A telescopic support 230 is provided at the lower end of the storage channels 220 to support the coffee capsules within them. Preferably, the telescopic support 230 can be an electromagnetic telescopic component. Coffee capsules can be placed one by one into the storage channels 220 and supported by the telescopic support 230. When a coffee capsule needs to fall downwards, the telescopic support 230 retracts and stops supporting it, allowing the capsule to fall. When the capsule coffee is stored in the storage channel 220, the annular part of the capsule coffee opening is limited in the limiting groove 221, so that the opening of the capsule coffee faces the upright plate 210. The capsule coffee is stored in the storage channel 220 in a flat state. When the capsule coffee is conveyed downward, the coffee powder will not cause the problem of falling out of the extraction hole.

[0041] Reference Figure 2 and Figure 5The cabinet 100 is equipped with a support rail 110, which is located on the bottom side of the upright plate 210. The translation device 300 is supported on the support rail 110 and extends the support rail 110 for translation. The receiving device 400 includes a rotary drive 410 and a receiving sleeve 420. The rotary drive 410 is located at the moving end of the translation device 300. The receiving sleeve 420 is connected to the rotary drive 410 and is provided with a collar 421 for receiving coffee capsules that fall from the storage channel 220. Specifically, when the receiving device 400 receives the coffee capsule, the translation device 300 drives the receiving sleeve 420 of the receiving device 400 to move to the bottom side of the storage channel 220. When the telescopic support 230 releases the coffee capsule, the coffee capsule falls from the storage channel. Under the influence of gravity and the center of gravity of the coffee capsule, the coffee capsule flips downwards, so that the bottom of the coffee capsule is facing down and falls into the collar of the receiving sleeve 420, making the coffee capsule stand upright. Preferably, the rotary drive 410 is a motor. Furthermore, a photoelectric switch 422 is also provided on one side of the receiving sleeve 420. The photoelectric switch 422 can detect whether there is a capsule in the receiving sleeve 420. When the photoelectric switch 422 detects that there is no capsule in the receiving sleeve 420, the capsule in the storage channel 220 will continue to fall until a capsule is detected in the receiving sleeve 420. In addition, when the photoelectric switch 422 detects that the capsule is inside the receiving sleeve 420, it first pours the capsule out and then moves to the bottom of the storage channel 220 to receive the capsule.

[0042] Reference Figure 1 The front side of the cabinet 100 has a recess 101, which forms a top plate 102. The top plate has a through hole (not shown in the attached figure). The recess 101 can hold containers such as cups for receiving brewed coffee.

[0043] Reference Figure 2 , Figures 6 to 8 The brewing device 500 includes a base 510 and a pressing mechanism 520. The base 510 is fixed above the top plate 102. The bottom side of the base 510 is provided with a guide groove 511 for positioning and receiving the sleeve 420. The pressing mechanism 520 is located on the base 510 and includes a piercing needle tube 521. The piercing needle tube 521 is connected to the water supply device 600.

[0044] Specifically, in this embodiment of the capsule-type automatic brewing machine, when capsule coffee extraction is needed, the receiving sleeve 420 is driven to the bottom of the storage channel 220 by the translation device 300. The telescopic support 230 releases the bottommost capsule coffee, causing the capsule coffee to flip downwards under the action of gravity, so that the bottom of the capsule coffee falls into the collar 421, and the edge of the capsule coffee mouth is supported on the collar 421. Then, the translation device 300 drives the capsule coffee to extend into the guide groove 511 of the seat 510. The pressing mechanism 520 presses down, puncturing the needle tube 521 to break the sealing film of the capsule coffee. The water supply device 600 injects hot water into the capsule coffee, completing the coffee extraction. The extracted liquid flows from the bottom into the cup of the concave cavity 101. After extraction, the receiving sleeve 420 is rotated 180° by the rotation drive 410, so that the waste capsule coffee falls from the receiving sleeve 420, thus completing the fully automatic coffee extraction. Because the bottom of the coffee capsule faces downwards during the extraction process, it can be extracted more thoroughly.

[0045] Furthermore, refer to Figures 2 to 4 To facilitate the better flipping and falling of the coffee capsule into the receiving sleeve 420, a stopper 240 is provided at the bottom of the storage channel 220. The stopper 240 has a clearance groove 241 with a bottom, and the opening of the clearance groove 241 is larger than the width between the two limiting grooves 221. The telescopic support 230 is located inside the clearance groove 241. In this embodiment, after the telescopic support 230 retracts, when the coffee capsule falls from the storage channel 220, the edge of the coffee capsule's opening hits the bottom of the stopper 240. The bottom of the stopper 240 blocks the edge of the coffee capsule's opening, while the other parts are not blocked, so the capsule flips downwards, achieving a 180° downward flip and falling into the support sleeve 420.

[0046] Furthermore, refer to Figures 2 to 4 To prevent other coffee capsules from falling, a limiting rod 250 is provided on the upright plate 210, located above the telescopic support member 230. This limiting rod 250 supports the second and subsequent coffee capsules in the storage channel 220. The limiting rod 250 is connected to a power member for pushing the limiting rod 250, which alternately supports the coffee capsules with the telescopic support member 230. Specifically, when a coffee capsule needs to fall into the receiving sleeve 420, the limiting rod 250 is first pushed to the bottom of the second coffee capsule to support the second and subsequent coffee capsules, and then the telescopic support member 230 retracts, causing the bottommost coffee capsule to fall into the receiving sleeve 420, thus preventing other coffee capsules from falling.

[0047] Preferably, refer to Figures 2 to 4The limiting rod 250 has guide rods 251 at both ends, which slide through the upright plate 210. The free end of the guide rod 251 has a downwardly extending push rod 252 for contacting the translation device 300. Additionally, the guide rod 251 is fitted with a compression spring 253, which abuts between the upright plate 210 and the limiting rod 250, pushing the limiting rod 250 away from the upright plate 210. The translation device 300 drives the receiving sleeve 420 to move to the bottom of the storage channel 220. The translation device 300 pushes the push rod 252, causing the limiting rod 250 to overcome the elastic force of the compression spring 253 and move towards the bottom of the coffee capsule, thus limiting the coffee capsule. Furthermore, when the translation device 300 moves away, the compression spring 253 causes the limiting rod 250 to reset and detach from the coffee capsule. In this embodiment, the translation device 300 pushes the limiting rod 250, which not only has a simple structure, but also ensures that the limiting rod 250 only limits the coffee capsule after the receiving device 400 has moved to the bottom of the storage channel 220. At other positions, it is supported by the telescopic support member 230, so that the coffee capsule can fall in an orderly manner.

[0048] Furthermore, multiple sets of storage channels 220 are arranged on the upright plate 210. Therefore, coffee capsules can be placed in each storage channel 220, increasing the storage capacity. The translation device 300 includes a moving beam 310, a moving seat 320, a first drive mechanism (not shown in the figures), and a second drive mechanism (not shown in the figures). The beam 310 has pulleys 311 at both ends, supported on the support rail 110. The beam 310 has grooves 312 on both sides, and the moving seat 320 has limiting rollers 321 on both sides, which are limited within the grooves 312. The first drive mechanism is connected to the beam 310 and drives the beam 310 to move on the support rail 110. The second drive mechanism is connected to the moving seat 320 and slides along the grooves 312. A rotary drive component 410 is mounted on the moving seat 320. In this embodiment, driven by the first and second driving mechanisms, the receiving sleeve 420 can be moved to the bottom of each storage channel 220 to receive the capsule coffee and transport the capsule coffee to the bottom of the seat 510. Specifically, the first and second driving mechanisms can be electric belt mechanisms, gear and rack mechanisms, and motor-driven mechanisms, or electric lead screw mechanisms.

[0049] Furthermore, please refer to Figure 9 ( Figure 9(This is a structural diagram of an embodiment with a detection plate on the upright plate). Each storage channel 220 also has a clearance hole 223 at its lower end. Detection plates 260 are provided on the front and rear sides of the upright plate 210. Opposite sides of the two detection plates 260 are provided with photoelectric switches 261 located on both sides of the clearance hole 223. Specifically, in this embodiment, when there are capsules in the storage channel 220, the two photoelectric switches 261 cannot sense each other. When there are no capsules in the storage channel 220, the two photoelectric switches 261 can sense each other through the clearance hole 223. Therefore, the receiving device 400 can be moved to the bottom of other storage channels 220 by the control system. After all storage channels 220 are empty, a replenishment message can be sent to the service terminal through the control system.

[0050] Furthermore, refer to Figures 6 to 8 The pressing mechanism 520 includes a pressing plate 522, a rotating shaft 523, a motor 524, and a connecting member 525. The base 510 has a clearance hole 512, and a guide sleeve 513 extends upward from the edge of the clearance hole 512. The pressing plate 522 slides within the guide sleeve 513, and the puncture needle tube 521 is mounted on the pressing plate 522. The rotating shaft 523 is rotatably connected to the upper end of the guide sleeve 513, and the motor 524 is connected to the rotating shaft 523 to drive its rotation. The rotating shaft 523 has an eccentric member 526. The upper end of the connecting member 525 extends a first connecting portion 527, which is rotatably connected to the eccentric member 526. The bottom end of the connecting member 525 has a second connecting portion 528, which is rotatably connected to the pressing plate 522. In this embodiment, the rotating shaft 523 is driven to rotate by the motor 524. Under the action of the eccentric member 526, the connecting member 525 swings. The swinging action of the connecting member 525 causes the lower pressure plate 522 to press down along the guide sleeve 513, thereby causing the piercing needle 521 to puncture the coffee capsule and inject hot water for extraction into the capsule. Furthermore, when the lower pressure plate 522 presses down, its bottom is pressed firmly against the opening of the coffee capsule, while its upper end remains within the guide sleeve 513. This prevents the coffee capsule from rupturing due to excessive pressure during extraction.

[0051] Furthermore, refer to Figures 6 to 8The guide sleeve 513 is provided with guide grooves 514 on both sides, and guide grooves 514 are provided with slide rods 515. The lower pressure plate 522 is provided with ears 529 on both sides, and the ears 529 are fitted onto the slide rods 515. A support spring 516 is fitted onto the slide rods 515, and the support spring 516 supports the lower pressure plate 522. In this embodiment, when the lower pressure plate 522 moves upward, the support spring 516 pushes the lower pressure plate 510 to return to its original position. In addition, under the action of the support spring 516, there is no gap in the lower pressure plate 522. Specifically, under the action of the support spring 516, the lower pressure plate 522 is always tightly connected to the connecting member 525, so that the downward pressing distance of the lower pressure plate 522 can be accurately controlled, avoiding the problem that the lower pressure plate 522 contacts the coffee capsule but does not receive the driving force, and then, after receiving the driving force, the lower pressure plate 522 will break the sealing film at the mouth of the coffee capsule.

[0052] Furthermore, the top of the lower pressure plate 522 forms a concave cavity, and the second connecting part 528 is rotatably connected within the concave cavity.

[0053] Furthermore, a sealing sleeve 530 is fitted onto the outer surface of the lower pressure plate 522, and the sealing sleeve 530 cooperates with the guide sleeve 513. During the extraction process, the sealing sleeve 530 presses tightly against the mouth of the coffee capsule, achieving a seal at the mouth, thus allowing coffee to be extracted under high pressure, improving the extraction effect.

[0054] Furthermore, a sealing horn member 531 extends downward from the bottom of the sealing sleeve 530, forming a suction cup structure. A piercing needle 521 extends downward from the sealing horn member 531. In this embodiment, after the piercing needle 521 punctures the membrane, the sealing horn member 531 adheres to and adheres to the surface of the membrane. Therefore, water leakage can be further prevented when water is injected into the capsule.

[0055] Furthermore, to facilitate cleaning of the punctured needle 521, a cleaning chamber 423 is also provided on the receiving sleeve 420. Please refer to... Figure 10A silicone sleeve 424 is provided inside the cleaning chamber 423. A gap exists between the outer wall of the silicone sleeve 424 and the inner wall of the cleaning chamber 423, allowing the silicone sleeve 424 to expand and deform. Specifically, after the capsule coffee extraction is complete, the translation device 300 drives the receiving sleeve 420 to retract a certain distance, positioning the silicone sleeve 424 at the bottom end of the piercing needle 421. The piercing needle 421 can then be inserted into the silicone sleeve 424, and the sealing horn 531 seals the top side of the receiving sleeve 420. Water is then injected into the silicone sleeve 424 to clean the piercing needle 421.
