That is, when the beverage contained in the cavity 5013 flows downward from the communication hole 5012c of the inner container bottom wall 5012b, the beverage floods between the inner container bottom wall 5012b and the upper end surface of the piercing member 502 to push the piercing member 502 to move downward to pierce the bottom of the housing 5011a, so that the beverage confined between the inner container bottom wall 5012b and the piercing member 502 can flow out through the outlet hole of the piercing member 502 and then flow out from the pierced portion of the bottom wall of the housing 5011 a.

Here, it should be noted that in the practical process with reference to fig. 1, the beverage capsule 500 may be used in a beverage brewing system 1000, wherein the beverage brewing system 1000 may further comprise: body 100, upper piercing member 200, drive mechanism 300, liquid bath 401, and heating device 406.

Specifically, the beverage capsule 500 is provided on the body 100, wherein the body 100 may include a frame 100a and a base 100b fixed together. As shown in figures 1 and 2, the base 100b has a brewing chamber portion 101 therein, the brewing chamber portion 101 defines a brewing chamber with an open top therein, the brewing chamber has a shape and a size substantially the same as those of the capsule body 501, so that the beverage capsule 500 can be placed in the brewing chamber, a through hole 1011 is formed through the bottom wall of the brewing chamber portion 101, and the through hole 1011 is in communication with the brewing chamber.

Further, the base 100b has a moving groove 102 extending in the up-down direction, the upper puncturing member 200 is provided in the moving groove 102 to be movable up and down, and the upper puncturing member 200 is located above the beverage capsule 500, and the upper puncturing member 200 has an upper puncturing needle 201 extending downward. As shown in FIGS. 1 and 2, the moving groove 102 is located above the brewing chamber portion 101 and communicates with the brewing chamber portion 101, the upper puncturing member 200 is fitted in the moving groove 102 and can move up and down in the moving groove 102, the upper puncturing needle 201 extends downward from the bottom of the upper puncturing member 200, so that when the upper puncturing member 200 moves downward to the lowest position in the moving groove 102, the upper puncturing needle 201 can puncture the top of the beverage capsule 500 (e.g., the lid body 5011b shown in FIG. 3), and thus an external liquid (e.g., hot water, etc.) can be injected into the housing chamber 5013 through the punctured portion of the lid body 5011b to mix with the beverage material 505 (e.g., coffee powder, etc.) in the housing chamber 5013 to obtain a beverage (e.g., coffee, etc.).

The driving mechanism 300 comprises a driving member 302 and a driven member 303, wherein the driving member 302 is pivotally arranged on the frame 100a, one end of the driven member 303 is pivotally connected with the driving member 302, and the other end is connected with the upper puncturing member 200 to drive the upper puncturing needle 201 of the upper puncturing member 200 to puncture the top of the beverage capsule 500. For example, in the example of fig. 1-3, the driving mechanism 300 may be configured as a crank-slider mechanism, and when the driving member 302 of the driving mechanism 300 pivots on the frame 100a, the driving member 302 may drive one end of the driven member 303 to rotate and the other end to move the upper piercing member 200 up and down in the moving slot 102, so that when the driving member 302 pivots to a certain position, the other end of the driven member 303 may drive the upper piercing member 200 to move to the lowest position of the moving slot 102 to pierce the top portion (e.g., the cover 5011b) of the beverage capsule 500.

The fluid bath 401 is connected to the beverage capsule 500 for supplying the liquid in the fluid bath 401 into the beverage capsule 500. As shown in FIG. 1, a liquid supply passage 202 is formed in the upper piercing member 200, one end of the liquid supply passage 202 penetrates through the lower end of the upper piercing member 201, and the other end of the liquid supply passage 202 penetrates through the outer wall of the upper piercing member 200 and is communicated with the liquid groove 401 through a liquid supply pipeline 402, so that when the upper piercing member 200 pierces the top of the beverage capsule 500 (such as the cover 5011b), the liquid in the liquid groove 401 can flow into the liquid supply passage 202 through the liquid supply pipeline 402 and then flow out from the lower end of the upper piercing member 201 to enter the accommodating cavity 5013 of the beverage capsule 500, thereby brewing the beverage.

Further, the liquid supply line 402 is provided with a heating device 406, and the heating device 406 is located between the upper piercing member 200 and the liquid tank 401, so that the liquid supplied from the liquid tank 401 to the housing chamber 5013 can be heated by the heating device 406 while flowing through the liquid supply line 402, and it can be ensured that the liquid flowing into the housing chamber 5013 can be a high temperature liquid.

In summary, during the process of brewing beverage, the beverage capsule 500 can be first placed in the brewing chamber, then the liquid (e.g., water) is led out from the liquid groove 401, and heated by the heating device 406, so that the obtained high-temperature liquid (e.g., hot water) is led into the upper piercing member 200, and at the same time, the driving mechanism 300 is operated to make the upper piercing member 200 pierce the top (e.g., tin foil) of the beverage capsule 500, so as to lead the high-temperature liquid into the containing cavity 5013, and contact and mix with the beverage material 505 (e.g., coffee powder) in the containing cavity 5013, so as to obtain brewed beverage (e.g., coffee, etc.), and then the beverage in the containing cavity 5013 can flow down through the communication hole 5012c on the bottom wall 5012b of the inner container, and the piercing member 502 is pushed downward by the pressure of the beverage to pierce the bottom wall 5011a, so that the beverage can flow out through the liquid outlet hole on the piercing member 502, and then flows out from the punctured portion in the bottom wall of the housing 5011a and finally flows out through the through hole 1011 in the bottom of the brewing chamber portion 101 to be drunk by the user.

According to the beverage capsule 500 provided by the embodiment of the invention, the piercing member 502 is arranged in the piercing cavity 5014 in the capsule body 501, so that the pressure of brewed beverage can be used for pushing the piercing member 502 to move downwards to realize internal piercing action, and the beverage capsule 500 is convenient to realize, safe and reliable.

In one embodiment of the invention, the outer periphery of the piercing member 502 is provided with a sealing ring 5031. As shown in fig. 3, the sealing ring 5031 is fitted between the outer peripheral surface of the puncture piece 502 and the inner peripheral surface of the liner peripheral wall 5012a and below the liner bottom wall 5012b, so that the liquid flowing down from the communication hole 5012c does not flow down below the upper end surface of the puncture piece 502 along the liner peripheral wall 5012a, that is, the beverage flowing down from the communication hole 5012c can only collect in advance between the lower end surface of the liner bottom wall 5012b and the upper end surface of the puncture piece 502, thereby ensuring that the beverage can effectively push the puncture piece 502 to move down to puncture the bottom wall of the housing 5011a, and further effectively ensuring that the inner puncture action can be performed smoothly and reliably.

Optionally, the outer periphery of the piercing member 502 is formed with a receiving groove in which the sealing ring 5031 is received. As shown in fig. 3, the puncturing member 502 may include a puncturing member top wall 5022 and a puncturing member peripheral wall 5021, wherein the puncturing member top wall 5022 has a shape and a size respectively matched with those of the partition, the puncturing member peripheral wall 5021 extends downward from the lower end surface of the puncturing member top wall 5022, and the receiving groove may be substantially annular and may be formed by recessing the puncturing member peripheral wall 5021 toward the central axis of the puncturing member top wall 5022, such that the sealing ring 5031 may be installed in the receiving groove to ensure that the sealing ring 5031 may be reliably clamped between the outer periphery of the puncturing member 502 and the inner circumferential surface of the inner container peripheral wall 5012a, and thus the problems of separation of the sealing ring 5031 from the puncturing member 502 and sealing failure are avoided, thereby further ensuring the reliability of sealing and further ensuring that the inner puncturing operation can be smoothly performed.

Preferably, the upper end of the sealing ring 5031 is provided with a sealing member 5032, and the inner circumference of the upper end of the sealing member 5032 is larger than the inner circumference of the lower end of the sealing member 5032, so that the sealing member 5032 can perform a self-locking function, that is, the higher the pressure of the beverage is, the better the sealing performance of the sealing member 5032 is. As shown in fig. 3, the sealing ring 5031 may be integrally formed with a sealing member 5032, wherein the lower end of the sealing member 5032 is connected to the upper end of the sealing member 5031, the upper end of the sealing member 5032 flares upward, the outer circumferential surface of the sealing member 5032 is fitted and sealed with the inner circumferential surface of the liner circumferential wall 5012a, and the inner circumferential surface of the sealing member 5032 is spaced from the outer circumferential surface of the puncturing member 502, and at this time, the beverage flowing from the communication hole 5012c may flow between the inner circumferential surface of the sealing member 5032 and the outer circumferential surface of the puncturing member 502, so as to further expand the sealing member 5032 to make the outer circumferential surface of the sealing member 5032 and the inner circumferential surface of the liner circumferential wall 5012a more tightly fit with each other, that is, the sealing is tighter, and the sealing effect.

Optionally, the seal 5032 is configured to taper in size from top to bottom inner perimeter. As shown in fig. 3, the outer peripheral dimension of the portion of the piercing member 502 corresponding to the seal 5032 in the up-down direction is equal from top to bottom, and the inner peripheral dimension of the seal 5032 gradually decreases from top to bottom, so that the gap between the inner peripheral surface of the seal 5032 and the outer peripheral surface of the piercing member 502 gradually decreases from top to bottom, so that the beverage can flow more smoothly between the inner peripheral surface of the seal 5032 and the outer peripheral surface of the piercing member 502 to effectively expand the seal 5032 to form a flare, so that the outer peripheral surface of the seal 5032 is fitted more tightly with the inner peripheral surface of the inner container peripheral wall 5012a, and the sealing effect is better.

Specifically, the lancet 5023 is provided on the lancet 502 extending downward, wherein at least one liquid outlet hole is formed on the lancet 5023. As shown in FIG. 3, the spike 5023 can project downwardly from the center of the lower end of the spike top wall 5022, and the exit port can extend through the spike 5023 in the up-down direction, preferably with the lower end of the spike 5023 being lower than the lower end of the spike perimeter wall 5021, such that when the spike 502 is mated in place with the inner container 5012, the upper end of the spike top wall 5022 contacts the lower end of the inner container bottom wall 5012b, and the lower end of the spike 5023 is positioned above the bottom wall of the housing 5011 a. Thus, as the lancet 5023 is pushed by the beverage to move downwardly, the lower end of the lancet 5023 can pierce the bottom wall of the housing 5011a downwardly until the lower end of the lancet perimeter wall 5021 abuts the upper end of the bottom wall of the housing 5011a and the lancet 502 stops moving, at which point the portion of the lancet 5023 extending beyond the lancet perimeter wall 5021 can extend and be exposed below the bottom wall of the housing 5011a to align with the through-holes 1011 in the brewing chamber portion 101 to deliver the beverage downwardly through the exit opening in the lancet 5023.

Further, the lancet 5023 can be hollow, with the bottom of the spacer provided with a downwardly extending projection 5012d, which projection 5012d mates with the lancet 5023. As shown in fig. 3, the spike 5023 may be formed with a fitting groove 5024 recessed downward from the upper end surface of the spike 5023, and a liquid outlet hole penetrates through the wall surface of the fitting groove 5024 to communicate with the fitting groove 5024, accordingly, the protrusion 5012d may be formed by downwardly protruding the inner container bottom wall 5012b, and the circumferential size and shape of the protrusion 5012d may be substantially the same as those of the upper portion of the fitting groove 5024 to be adapted, so that when installed, the fitting groove 5024 may be fitted over the protrusion 5012d, so that the puncturing member 502 may be fitted with the inner container bottom wall 5012b, and the puncturing member 502 may be in an initial position, i.e., the upper end surface of the puncturing member 502 may contact with the lower end surface of the inner container bottom wall 5012b, and thus the lower end of the spike 5023 may be initially located above the bottom wall of the housing 5011a, i.e., the bottom wall of the housing 501.

As shown in fig. 3, the communication hole 5012c is located on the side of the protrusion 5012d away from the central axis of the bottom wall 5012b of the liner so that the communication hole 5012c does not penetrate through the protrusion 5012d so that the communication hole 5012c is spaced apart from the protrusion 5012d in the horizontal direction, since the protrusion 5012d is vertically opposite to the spike 5023 and the liquid outlet hole penetrates through the spike 5023 so that the liquid outlet hole is horizontally spaced apart from the communication hole 5012c, that is, the communication hole 5012c is not vertically opposite to the liquid outlet hole, so that the liquid flowing out from the communication hole 5012c can first push the puncturing member 502 to move downward to puncture the inner wall of the housing 5011a instead of directly flowing out from the liquid outlet hole, thereby ensuring the reliability of the internal puncturing action.

Further, the bottom inside the lancet 5023 is provided with an upwardly extending rib 5025. As shown in fig. 3, when the lancet 502 is in the initial installation position, that is, the upper portion of the engagement groove 5024 is engaged with the protrusion 5012d, and the upper end surface of the lancet top wall 5022 is in contact with the lower end surface of the inner container bottom wall 5012b, the wall surface of the lower portion of the engagement groove 5024 and the lower end surface of the protrusion 5012d may together define a cavity, the rib 5025 is located in the cavity and is formed by upwardly protruding the bottom wall of the engagement groove 5024, and the upper end of the rib 5025 may abut against the lower end surface of the protrusion 5012d, so that the beverage flowing down from the communication hole 5012c may smoothly push the lancet 502 to move down, thereby improving the reliability of the lancet 5023 in piercing the bottom wall of the housing 5011, and the beverage may be collected in the cavity to be more intensively discharged, and preferably, the rib 5025 is integrally formed with the lancet 5023, thereby ensuring the overall strength of the lancet 5023 and saving the cost.

The upper portion of the receiving cavity 5013 is provided with a filter 504, and the filter 504 is formed with a plurality of filter holes 5041 uniformly spaced apart.
