Abstract
Description
Technical Field
[0001] This utility model relates to the field of coffee machine technology, and in particular to a capsule coffee brewing mechanism. Background Technology
[0002] Capsule coffee is made by first grinding coffee beans into coffee powder and then filling them into aluminum capsules. This eliminates the problems of ordinary coffee beans or coffee powder turning sour or oxidizing after being exposed to air. When you want to brew coffee, you only need to put a coffee capsule into the brewing mechanism, connect it to the coffee machine, and it will be ready in 25 seconds. With the improvement of living standards and the acceleration of the pace of life, the method of brewing coffee with capsules is being accepted and loved by more and more people.
[0003] Patent CN219895381U, entitled "A Convenient Coffee Machine Capsule Funnel Structure," discloses a convenient coffee machine capsule funnel structure. The brewing base is fixedly connected to the bottom of the funnel, and a capsule cup assembly is placed inside the funnel. The capsule cup assembly includes a cup body adapted to accommodate a coffee capsule, with a needle at the bottom for piercing the bottom of the coffee capsule body. A liquid passage hole is formed on the bottom of the cup. The brewing base includes a base plate and a surrounding cylindrical portion. A supporting protrusion is formed on the base plate for abutting against the flange portion connecting the coffee capsule, and a liquid outlet hole is formed on the base plate, located within the supporting protrusion. A pressing edge is formed at the lower end of the cup body for abutting against the flange portion connecting the coffee capsule. Radial positioning ribs are formed on the inner side of the surrounding cylindrical portion for surrounding the flange portion of the coffee capsule. The capsule cup assembly can detach from the funnel through the funnel inlet. This utility model's coffee machine capsule funnel structure facilitates convenient and quick coffee capsule installation, and its structure is rationally designed and stable.
[0004] In existing technologies, when a capsule is punctured, the gap between the coffee capsule and the brewing head causes the high-pressure hot water in the coffee machine to be depressurized after entering the capsule, failing to reach the pressure required for brewing coffee, thus affecting the brewing quality; at the same time, these structures are only designed for small capsules and cannot meet the needs of large capsules. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing a capsule coffee brewing mechanism that can guarantee brewing pressure and has high adaptability.
[0006] To solve the above-mentioned technical problems, the present invention is solved by the following technical solution: a capsule coffee brewing mechanism, including a compatible unit and a brewing seat assembly movably connected to the compatible unit.

[0012] In the above technical solution, an auxiliary inner seat with an open top is provided inside the brewing station. A mating part is provided at the eaves of the open top of the auxiliary inner seat. Several piercing protrusions are provided on the inner bottom surface of the auxiliary inner seat. A liquid outlet hole is provided on the inner bottom surface between the piercing protrusions. The liquid outlet hole is used to allow coffee liquid to flow into the working chamber of the brewing station and then flow out from the liquid outlet.
[0013] In the above technical solution, a capsule receiving seat with an open bottom is provided in the cavity of the auxiliary inner seat. The bottom opening end of the capsule receiving seat is provided with an overlapping part that cooperates with the annular platform on the inner bottom surface of the auxiliary inner seat. A through hole is provided on the first working surface at the other end of the capsule receiving seat. A connecting part that cooperates with the sealing connection part is provided along the circumference of the through hole and protruding from the first working surface. A spike is provided along the circumference of the through hole and protruding from the second working surface, mainly for puncturing small capsules.
[0014] In the above technical solution, the water inlet channel is provided with a threaded groove, and the drainage needle is movably connected to the water outlet end of the water inlet channel through the threaded groove, making disassembly and cleaning more convenient.
[0015] In the above technical solution, the compatibility device is provided with a brewing handle connection part, making the operation simpler and faster.
[0016] Compared with the prior art, this utility model has the following advantages: by setting a flow-guiding needle on the compatibility device that is coaxial with the water inlet channel and vertically suspended in the second cavity, and cooperating with the brewing seat assembly, a sealing structure is formed at the puncture connection, ensuring that the high-pressure hot water in the coffee machine can still maintain the brewing pressure after entering the capsule after puncture, thus achieving a good brewing taste; the compatibility device and the corresponding brewing seat assembly can be used together to meet the brewing needs of small capsules without affecting the use of large capsules, making it more versatile. One mechanism can meet multiple brewing needs, which helps to reduce the user's operating costs. Attached Figure Description

[0028] See Figures 1 to 6 A capsule coffee brewing mechanism includes a compatible unit 1 and a brewing seat assembly 2 movably connected to the compatible unit 1.
[0029] The compatibility unit 1 includes a shell that is open at both ends. A partition structure 11 is provided in the inner cavity of the shell to divide the inner cavity of the shell into a first cavity 12 and a second cavity 13, that is, the top of the first cavity 12 is open and the bottom of the second cavity 13 is open.
[0030] The upper working surface of the partition 11 structure is a plane, located inside the first cavity 12, and becomes the bottom of the first cavity 12. A funnel-shaped concave structure is set at the center of this plane, and a water inlet channel is opened along the center of the concave structure, passing through the partition 11 structure, so that the first cavity 12 and the second cavity 13 are interconnected.
[0031] The lower working surface of the partition 11 structure is located inside the second cavity 13, becoming the top wall of the second cavity 13. A mating sealing reserved part is provided on the top of the second cavity 13. Of course, this mating sealing reserved part is arranged circumferentially along the water inlet channel. Since the cross-section of our compatible device 1 is designed to be circular, the corresponding mating sealing reserved part is an annular groove arranged circumferentially along the water inlet channel. Of course, it is not limited to this shape and can be modified according to the most suitable shape of our compatible device 1.
[0032] The lower working surface of the partition 11 structure is also equipped with a drainage needle 3. The drainage needle 3 is a hollow structure with open ends. A piercing part is provided at the working end, and a connection structure with the water inlet channel is provided at the connecting end. For easy disassembly and assembly, the outer wall of the drainage needle 3 is provided with a threaded structure, and correspondingly, the inner wall of the water inlet channel is provided with a threaded groove. The drainage needle 3 is movably connected to the water outlet end of the water inlet channel through the thread, and the working part of the drainage needle 3 is suspended in the second cavity 13.
[0033] Of course, this connection method is not limited to threaded connections; other methods that facilitate disassembly and assembly, such as snap-fit connections, can also be used.
[0034] To ensure that the high-pressure hot water in the coffee machine maintains brewing pressure after the capsule is punctured, a sealing module 15 from the brewing connection structure is connected to the sealing pre-reserved part. The sealing module 15 is a connecting block structure with a sealing connection part 151 in the middle that allows the flow-guiding needle 3 to pass through and can cooperate with the brewing seat assembly 2 to form a seal after puncture, i.e., a through hole structure.
[0035] Of course, in order to connect the compatibility unit 1 to the coffee machine, a brewing connection structure 14 is provided on the outer wall of the first cavity 12, which can be engaged with the water outlet of the coffee machine during use, freeing up the hands. At the same time, for convenient operation, a brewing handle connection part 10 is provided on the outer wall of the compatibility unit 1 for connecting the operating handle. More specifically, the brewing handle connection part 10 is located on the outer wall of the second cavity 13.
[0036] The inner wall of the second cavity 13 is provided with a first connecting structure 131 in the brewing connection structure. For ease of operation, a threaded groove connection method is selected, but a slot or other method can also be selected.
[0037] The brewing base assembly 2 includes a brewing base 21, an auxiliary inner base 22, and a capsule container 23, which are stacked sequentially from the outside to the inside.
[0038] Among them, the brewing seat 21 is located at the outermost part, meaning that the working chamber of the brewing seat 21 is the largest and can accommodate the auxiliary inner seat 22. The brewing seat 21 has a top-open cavity structure, and a mating connection part 211 that connects to the first connecting structure is provided on the outer cavity wall. Of course, when the first connecting structure 131 adopts a threaded groove connection method, the corresponding mating connection part 211 adopts a threaded structure. A liquid outlet 212 is provided on the bottom of the working cavity of the brewing seat. An overlapping platform 214 is provided at the transition between the bottom of the cavity and the cavity wall. To facilitate liquid discharge, a funnel-shaped contraction structure is provided at the transition between the bottom of the cavity and the cavity wall. A rib 213 is provided at the bottom of the working cavity along the circumference of the liquid outlet 212.
[0039] The auxiliary inner seat 22 is set inside the brewing seat 21 and has the same structure as the brewing seat 21. It is also a cavity structure with an open top. The upper open end of the auxiliary inner seat 22 is provided with a fitting part 221, which can be used to set on the eaves of the brewing seat 21 when it is used with the brewing seat 21. Several piercing protrusions 222 are provided on the inner bottom surface of the auxiliary inner seat 22. Liquid outlet holes 223 are provided on the inner bottom surface between two adjacent piercing protrusions 222.
[0040] An overlapping step that mates with the overlapping platform 214 is provided at the transition between the outer wall of the auxiliary inner seat 22 and the bottom of the cavity. Of course, the auxiliary inner seat 22 can be stably placed in the brewing seat 21 during use. Several limiting ribs are provided on the outer wall of the auxiliary inner seat 22, which mate with the limiting groove on the inner wall of the brewing seat 21 for limiting. At the same time, the upper end of the limiting groove on the inner wall of the brewing seat 21 is open, which can also play a guiding role.
[0041] The capsule receiving seat 23 is disposed within the cavity structure of the auxiliary inner seat 22. The bottom of the auxiliary inner seat 22 is open. A through hole is provided on the first working surface 232 at the other end of the capsule receiving seat 23, i.e. the top. A connecting mating part 233 that mates with the sealing connection part 151 is provided along the circumference of the through hole and protruding from the first working surface 232. A spike part 234 is provided along the circumference of the through hole and protruding from the second working surface, i.e., the side facing the bottom. The working end of the spike part 234 is suspended in the cavity of the auxiliary inner seat 22.
[0042] Several spikes 234 can be distributed along the circumference of the through hole, preferably evenly distributed along the circumference of the through hole, which is beneficial to obtaining a uniform piercing effect.
[0043] The capsule receiving seat 23 has an overlapping part 231 at the bottom opening end, which can be placed on the annular platform on the inner bottom surface of the auxiliary inner seat 22 during assembly.
[0044] In order to ensure that the brewing structure can meet the needs of both small capsules and large capsules, the brewing base component 2 adopts a free combination method to adapt to different usage requirements.
[0045] See Figures 3 to 4 At this point, brewing unit 2 only needs to use compatibility unit 1 and brewing unit 21 to complete the brewing action.
[0046] This combination is suitable for brewing large capsule 4. When brewing, large capsule 4 is placed upright in brewing stand 21, that is, the top sealing film is facing up, and the edge of large capsule 4 is placed on the edge of brewing stand 21. When the compatible unit 1 is assembled with brewing stand assembly 2, the flow needle 3 punctures the sealing film on the top of large capsule 4, and the sealing module 15 fits against the sealing film surface of large capsule 4 to ensure airtightness. The brewing mechanism is connected to the water outlet of the coffee machine via the bubble connection structure 14. When the high-pressure hot water in the coffee machine is guided into the capsule through the flow needle 3, the sealing module 15 adheres to the sealing film surface of the large capsule 4, ensuring a tight seal. Therefore, the brewing pressure can be maintained, resulting in a good brewing taste. At the same time, the large capsule 4 has a built-in puncture structure 41. Under the action of back pressure, the puncture structure 41 punctures the sealing film located at the bottom of the large capsule 4, allowing the coffee liquid to flow out from the outlet reserved at the bottom of the capsule, and then out from the liquid outlet 212, completing the brewing of the large capsule 4.
[0047] See Figures 5 to 6 When brewing small capsules, the following are required: compatibility unit 1, brewing base 21, auxiliary inner base 22, and capsule container 23.
[0048] During brewing, the capsule holder 23 is inverted, and the small capsule is placed upright inside from the bottom open end. Then, the capsule holder 23 is placed in the auxiliary inner seat 22 with the bottom open end facing down. At this time, the small capsule sealing film contacts the piercing protrusion 222 of the auxiliary inner seat 22, and the bottom of the small capsule is pre-pierced by the spike 234. The brewing mechanism is engaged with the water outlet of the coffee machine through the bubble connection structure 14. The connecting part 233 is inserted into the sealing connection part 151, and the flow-guiding needle 3 plays a guiding role at this time, so that the space inside the small capsule remains relatively sealed. This ensures that the high-pressure hot water in the coffee machine can still maintain the brewing pressure after entering the capsule after piercing, achieving a good brewing taste. The small capsule sealing film is pierced by the piercing protrusion 222, and the coffee liquid flows out from the outlet 212, completing the brewing of the small capsule.
[0049] The above-mentioned structural combination is flexible and easy to use. It can meet the needs of brewing small capsules without affecting the use of large capsules, making it more applicable and having a good market prospect.
[0050] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
