[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0036] On the one hand, such as Figure 1 and Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a coffee extraction funnel according to one embodiment of the present invention includes a funnel body 1 and a coffee basket 2. The coffee basket 2 includes a basket body 21 with an upper opening and a basket cover 22 disposed on the upper opening. The basket body 21 has a plurality of drainage holes, and the basket cover 22 has a water passage hole for communicating with the inner cavity space of the basket body 21. The basket body 21 and the basket cover 22 are provided with a piercing structure 3 facing the inner space of the basket. The funnel body 1 includes a placement seat 11, the placement seat 11 has a vertically penetrating placement cavity 101, the upper end of the placement cavity 101 is provided with a limiting concave edge 102, and the outer wall of the basket body 21 is provided with a limiting convex edge 201 adapted to the limiting concave edge 102. Specifically, the basket wall and the bottom of the basket body 21 are provided with a plurality of drainage holes.

[0037] The aforementioned coffee extraction funnel utilizes the engagement of the limiting concave edge 102 and the limiting convex edge 201 to place the basket 21 into the placement cavity 101 of the placement seat 11. Coffee capsules or coffee powder are then placed into the basket 21, and the basket lid 22 is closed. After placing the coffee extraction funnel into the coffee machine, the coffee machine drives the basket lid 22 to fit tightly against the basket 21, thus achieving the coffee brewing action. Specifically, when a coffee capsule is placed in the basket 21, the coffee machine drives the basket lid 22 to move downwards, piercing the top and bottom of the coffee capsule with the piercing structure 3. Hot water enters the aluminum capsule container through the water inlet and flows into the brewing container through the piercing hole and drain hole at the bottom.

[0038] In one embodiment, the puncture structure 3 includes a first puncture unit 31 disposed on the basket cover 22. The first puncture unit 31 includes a puncture needle disposed at the center of the basket cover 22, and the water passage is disposed at the center of the puncture needle. In this way, while the puncture needle punctures the aluminum capsule box, hot water is introduced into the aluminum capsule box through the water passage for brewing.

[0039] In one embodiment, the basket 21 is a frustoconical shell that is narrower at the bottom and wider at the top. Thus, by utilizing the outer diameter surface of the frustoconical shell to contact the inner wall of the placement cavity 101, the installation position of the basket 21 relative to the placement seat 11 is defined, thereby improving adaptability.

[0040] In one embodiment, the top of the placement seat 11 is provided with a positioning claw. In this way, by using the positioning claw to cooperate with the coffee machine, the coffee machine can fix the placement seat 11 to drive the basket cover 22 to move downward relative to the placement seat 11, thereby realizing the capsule coffee piercing action.

[0041] In one embodiment, the cover 22 has a sealing structure along its edge; the bottom of the basket 21 has a second puncture unit 32. Specifically, the second puncture unit 32 includes a puncture tip located at the center of the bottom of the basket 21 and a fluid channel located at the puncture tip, the fluid channel passing through the center of the puncture tip and being in a straight line or cross shape.

[0042] Example 1

[0043] like Figure 1 and Figure 2 As shown, in one embodiment, the funnel body 1 further includes a heightening ring 12 disposed above the placement seat 11 and a flow-diverting structure 13 disposed below the placement seat 11. The heightening ring 12 is connected to the placement seat 11 via a limiting structure 4. Thus, the height of the placement cavity 101 is increased by the heightening ring 12, thereby accommodating the coffee basket 2 to accommodate capsule coffee or coffee powder. Simultaneously, due to the large volume of the coffee basket 2, the flow-diverting structure 13 at the bottom can be used to brew two cups of coffee. Furthermore, the heightening ring 12 and the coffee basket 2 can be removed according to personal preference to fill with a regular small cup for brewing a single cup of coffee.

[0044] In one embodiment, the limiting structure 4 includes a limiting groove 41 disposed at the limiting recess 102 of the placement seat 11 and a limiting protrusion 42 disposed at the bottom of the raising ring 12. Thus, by using the limiting protrusion 42 to fit the limiting groove 41, the raising ring 12 and the placement seat 11 cannot move relative to each other during use, ensuring the temperature stability of the structure.

[0045] Example 2

[0046] like Figure 3 and Figure 4 , Figure 5As shown, in one embodiment, the overall height of the coffee basket 2 is greater than that of the placement seat 11, and the funnel body 1 also includes a diverter seat 14, which is connected to the placement seat 11 via a mounting structure 5. Thus, by disassembling the diverter seat 14, when the coffee basket 2 is placed on the placement seat 11, the bottom of the coffee basket 2 protrudes from the placement cavity 101, allowing the coffee liquid to flow directly from the bottom of the basket 21 for brewing.

[0047] In one embodiment, the mounting structure 5 includes a concave edge 51 at the bottom of the placement seat 11, an L-shaped hook 52 on the concave edge 51, and a positioning groove 53 on the inner wall of the diverter seat 14, wherein the positioning groove 53 is adapted to the L-shaped hook 52. Specifically, the length of the L-shaped hook 52 is less than the inlet width of the positioning groove 53. Thus, by aligning the L-shaped hook 52 with the inlet of the positioning groove 53, the L-shaped hook 52 engages with the positioning groove 53, and the diverter seat 14 is rotated, thereby fixing the diverter seat 14 to the bottom of the diverter seat 14. The disassembly action is simple and reliable.

[0048] On the other hand, one embodiment of the present invention provides a coffee machine including a coffee main unit and a coffee extraction funnel. Thus, after placing a coffee capsule or coffee powder into the basket 21, closing the basket lid 22, and placing the coffee extraction funnel into the coffee main unit, the coffee main unit drives the basket lid 22 to fit tightly against the basket 21, thereby indicating the coffee brewing process.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
