[0004] The existing extraction box of this type of coffee machine can only be loaded with ground coffee powder for extraction, and is not suitable for other forms of coffee, such as capsule coffee. Therefore, it is difficult to adapt to consumers with different requirements, has a single function, and has a poor user experience.

[0005] To this end, the applicant has made improvements, as disclosed in the Chinese patent application number 202321668034.9, which provides a needle and a bursting plate to enable the coffee extraction box to be used for capsule coffee. However, due to slight deviations in the height and size of capsules of different brands on the market, the structure of the capsule box disclosed in the above patent cannot ensure sealing and compatibility, and further improvements are needed. Utility Model Content

[0006] The first technical problem to be solved by the utility model is to provide a coffee capsule box with improved sealing and compatibility in view of the deficiencies in the above-mentioned prior art.

[0007] The second technical problem to be solved by the present invention is to provide a coffee brewing device using the above-mentioned coffee capsule box.

[0008] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a coffee capsule box, comprising an upper cover, a lower cover and a capsule, wherein the upper cover is provided with a first through hole for water from a main unit of a coffee brewing device to enter, and the lower cover is provided with a second through hole at the lowest position for the extracted coffee to flow out;

[0009] A capsule bin for accommodating capsules is arranged in the space formed between the upper cover and the lower cover, the first through hole is in fluid communication with the capsule bin, and the capsule bin comprises a hollow bin body and a bursting plate arranged at the bottom of the bin body for bursting the capsules; the characteristics are:

[0010] The capsule compartment further comprises a first sealing ring, which abuts against the periphery of the capsule and is pressed tightly against the bursting plate.

[0011] By providing the first sealing ring, the periphery of the capsule can be sealed with the bin body and the bursting plate respectively, so as to prevent water from leaking from the bin body and the periphery of the capsule from the upper cover, and also to prevent coffee liquid from leaking from the periphery of the capsule when the aluminum foil of the capsule is punctured by the protrusion of the bursting plate; in addition, there are slight deviations in the heights and sizes of capsules of different brands on the market, and by providing the first sealing ring, these deviations can also be eliminated, so that capsules of different heights and sizes can be stably installed and well sealed.

[0012] Furthermore, in order to facilitate fixing the position of the first sealing ring, an annular groove is formed at the bottom of the warehouse body. The groove is formed by the bottom surface of the warehouse body being recessed in a direction away from the bursting plate, and the first sealing ring is stuck in the groove.

[0013] Furthermore, a notch is formed around the first sealing ring, and the notch is formed by the outer peripheral wall of the first sealing ring being radially inwardly recessed. The notch can be used as an exhaust groove during installation to prevent the residual gas inside from being heated and lifting the first sealing ring as a whole during use.

[0015] Furthermore, in order to facilitate the bursting of the capsule and the flow of the burst coffee from the lower cover, the bursting plate includes a plate body, a protrusion arranged on the side of the plate body facing the warehouse body, and a liquid outlet hole opened on the plate body. When the bursting plate is closed, the protrusion on the plate body extends into the warehouse body and can puncture the capsule when the capsule expands. The first sealing ring is pressed against the position of the bursting plate located on the overall periphery of the protrusion.

[0016] Furthermore, the protrusions of the bursting plate are prism-shaped, and the side surfaces of the protrusions are transitioned with rounded corners. Under the same pressure, the rounded corners can make the bursting holes pierced by the protrusions smaller, and the sizes of the bursting holes corresponding to the protrusions are more uniform.

[0017] In order to facilitate the bursting plate to open and close the warehouse body, the plate body is rotatably connected to the warehouse body.

[0018] Furthermore, the inner circumferential wall of the bin body is provided with convex ribs, and the convex ribs are in plurality and arranged at intervals along the circumference of the bin body, and each convex rib extends along the height direction of the capsule. Since there are slight deviations in the sizes of capsules of different brands on the market, through the provision of the convex ribs, when the sizes are different, the forces exerted on the capsules by the convex ribs are also different, so that the space in the bin body can be adapted to capsules of different sizes.

[0019] Furthermore, the coffee capsule box also includes a pricking needle that penetrates into the capsule compartment and the capsule from the upper cover, the pricking needle includes a body and a needle portion, the body is located at the top of the capsule compartment, and the needle portion extends into the capsule compartment, and the body and the top of the capsule compartment are connected by an opening so that the first through hole and the fluid in the capsule compartment are connected, and by providing the pricking needle, water from the upper cover can enter the capsule.

[0020] The technical solution adopted by the utility model to solve the second technical problem is: a coffee brewing device, including a main unit, characterized in that: the coffee capsule box as described above is applied.

[0021] Compared with the prior art, the advantages of the utility model are: by providing the first sealing ring, the periphery of the capsule can be sealed with the bin body and the bursting plate respectively, so as to prevent water from leaking from the bin body and the periphery of the capsule from the upper cover, and also to prevent coffee liquid from leaking from the periphery of the capsule when the aluminum foil of the capsule is punctured by the protrusion of the bursting plate; in addition, there are slight deviations in the heights and sizes of capsules of different brands on the market, and by providing the first sealing ring, these deviations can also be eliminated, so that capsules of different heights and sizes can be stably installed and well sealed.

[0033] See also Figures 1 to 7 A capsule box of a coffee brewing device includes an upper cover 21, a lower cover 22, a capsule compartment 23 and a pricking needle 24. The upper cover 21 and the lower cover 22 can be fastened by threaded connection, and the capsule compartment 23 is arranged in the space formed between the upper cover 21 and the lower cover 22. The capsule compartment 23 is used to accommodate capsules 25. The upper cover 21 is provided with a first through hole 211 for hot water from a main unit of the coffee brewing device to enter, and the lower cover 22 is provided with a second through hole 221 at the lowest position for the extracted coffee to flow out.

[0034] A gasket 26 is provided at the bottom of the first through hole 211 in the upper cover 21, and the gasket 26 is pressed between the top of the capsule compartment 23 and the bottom of the first through hole 211. A third through hole 261 corresponding to the first through hole 211 is provided on the gasket 26. The puncture needle 24 includes a body 241 and a needle portion 242, and the body 241 is located at the top of the capsule compartment 23 and pressed between the gasket 26 and the capsule compartment 23, and the needle portion 242 extends into the capsule compartment 23.

[0035] The capsule bin 23 includes a hollow bin body 231 and a bursting plate 232 disposed at the bottom of the bin body 231. The cavity formed by the bin body 231 is adapted to the shape and size of the capsule 25. The bottom of the bin body 231 is open. The bursting plate 232 is disposed at the opening at the bottom of the bin body 231. The capsule 25 can be loaded into the bin body 231 through the opening at the bottom of the bin body 231. The bursting plate 232 is rotatably connected to the bin body 231, so that the bin body 231 can be opened when the capsule 25 needs to be replaced, and the bin body 231 can be closed after the capsule 25 is loaded. The bin body 231 can be fixed to the upper cover 21 by fasteners such as screws. A fourth through hole 2411 is provided on the body 241 of the above-mentioned puncture needle 24, and a fifth through hole 2311 is provided at a corresponding position on the top of the storage body 231, thereby hot water can enter the interior of the storage body 231 from the third through hole 261 of the gasket 26, the fourth through hole 2411 of the body 241 of the puncture needle 24 and the fifth through hole 2311 of the storage body 231, and the needle portion 242 of the puncture needle 24 can penetrate into the capsule 25, thereby connecting the first through hole 211 of the upper cover 21 and the capsule 25 with the fluid, and thus the hot water entering the storage body 231 can enter the capsule 25 through the position where the capsule 25 is punctured by the puncture needle 24 for extraction.

[0036] The bursting plate 232 includes a plate body 2321, a protrusion 2322 arranged on the side of the plate body 2321 facing the warehouse body 231, a buckle 2323 arranged on the plate body 2321, and a liquid outlet 2324 opened on the plate body 2321. The plate body 2321 is rotatably connected to the warehouse body 231. When the bursting plate 232 is closed, the protrusion 2322 on the plate body 2321 extends into the warehouse body 231. When the high-pressure hot water passes through the capsule 25, the capsule 25 swells under the action of the water pressure, and the aluminum foil of the capsule 25 can be punctured by the protrusion 2322, so that the extracted coffee can flow downward from the punctured position at the bottom of the capsule 25, flow to the bottom of the bursting plate 232 through the liquid outlet 2324, and finally can be discharged through the second through hole 221 at the bottom of the lower cover 22.

[0037] The bottom of the chamber body 231 is also formed with a slot 2312, and the buckle 2323 of the bursting plate 232 can cooperate with the slot 2312 to clamp and fix the chamber body 231 and the bursting plate 232, thereby enclosing the capsule 25 inside the capsule chamber 23. The positions of the slot 2312 and the buckle 2323 are interchangeable.

[0038] The protrusion 2322 of the bursting plate 232 is in the shape of a prism, such as in the present embodiment, a quadrangular prism with a small top surface and a large bottom surface, and the side surfaces 2325 of the prism are transitioned by rounded corners 2326, that is, the edges of the prism are arcs rather than points on the cross section of the protrusion 2322. Under the same pressure, by forming the rounded corners 2326, the bursting holes pierced by the protrusion 2322 can be made smaller, and the sizes of the bursting holes corresponding to the protrusions 2322 are more uniform.

[0039] The capsule bin 23 also includes a first sealing ring 233. A groove 2313 is formed at the bottom of the bin body 231. The groove 2313 is formed by the bottom surface of the bin body 231 being recessed in a direction away from the bursting plate 232. The groove 2313 is annular. The first sealing ring 233 is inserted into the groove 2313. When the capsule 25 is loaded, the first sealing ring 233 can abut against the periphery of the capsule 25 (the periphery of the aluminum foil of the capsule) and thereby press the periphery of the capsule 25 and the bursting plate 232 at the position of the overall periphery of the protrusion 2322. Here, the overall periphery of the protrusion 2322 refers to the periphery of the arrangement range of the multiple protrusions 2322 when there are multiple protrusions 2322. Thus, by providing the first sealing ring 233, the periphery of the capsule 25 can be sealed with the bin body 231 and the bursting plate 232, respectively, to prevent water from the upper cover 21 from leaking between the bin body 231 and the periphery of the capsule 25, and to prevent coffee liquid from leaking from the periphery of the capsule 25 when the aluminum foil of the capsule 25 is punctured by the protrusion 2322 of the bursting plate 232. In addition, there are slight deviations in the heights and sizes of capsules 25 of different brands on the market, and by providing the first sealing ring 233, these deviations can also be eliminated, so that capsules 25 of different heights and sizes can all be stably installed and well sealed.

[0040] The first sealing ring 233 is formed with a notch 2331 around it. There may be multiple notches 2331, which are formed by the outer peripheral wall of the first sealing ring 233 being recessed radially inward. The notch 2331 may extend along the height direction of the first sealing ring 233 and extend to both ends of the height direction of the first sealing ring 233 (i.e., forming a through shape). The notch 2331 may be used as an exhaust groove during installation to prevent the residual gas inside from being heated and lifting the first sealing ring 233 as a whole during use.

[0041] The inner circumferential wall of the bin body 231 is provided with ribs 2314, and there are multiple ribs 2314 arranged at intervals along the circumference of the bin body 231, and each rib 2314 extends along the height direction of the capsule 25. The ribs 2314 press the capsule 25 into the bin body 231 to prevent it from being loose. As mentioned above, the sizes of capsules 25 of different brands on the market have slight deviations. By setting the ribs 2314, when the sizes are different, the forces of the ribs 2314 on the capsule 25 are also different, so that the space in the bin body 231 can be adapted to capsules 25 of different sizes.

[0042] In order to improve the sealing performance and provide a better sealed extraction space for coffee extraction, a second sealing ring 271 and a third sealing ring 272 are respectively provided between the gasket 26 and the upper cover 21 and between the chamber body 231 and the upper cover 21.

[0043] See also Figure 8 When the capsule 25 needs to be loaded, first unscrew the upper cover 21 and the lower cover 22 to separate them, then rotate the bursting plate 232 to open the warehouse body 231, and after loading the capsule 25, rotate the bursting plate 232 again to close the warehouse body 231. After closing, the buckle 2323 and the slot 2312 cooperate to fix the position of the bursting plate 232 and the warehouse body 231, thereby enclosing the capsule 25 inside the capsule warehouse 23.

[0044] The "fluid communication" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
