[0003] In the related art, when drip coffee is brewed, a filter cup and filter paper are often used. The user folds the filter paper into a cone shape and places it in the filter cup with the tip of the filter paper facing down; then the coffee bean powder is placed in the filter paper, and then hot water is injected into the filter paper. The hot water and coffee bean powder are mixed to form espresso, which drips out from the bottom of the filter paper; when the espresso passes through the filter paper, the filter paper can filter out the bean residue and oil in the espresso, and the coffee bean powder can be more fully dissolved in the water.

[0004] However, after the filter paper is folded into a cone shape, the cross-sectional area of ​​the bottom of the filter paper is small, and the coffee bean powder accumulates at the bottom of the filter paper, making it difficult for the coffee bean powder at the bottom of the filter paper to come into contact with water, reducing the degree of solubility of the coffee bean powder at the bottom of the filter paper, thereby affecting the taste and flavor of the coffee.

[0034] The coffee filter cup 100 provided in the embodiment of the present application will be described in detail below through specific embodiments in conjunction with all the drawings in the specification.

[0035] Please refer to Figure 1In one embodiment of the present invention, a coffee filter cup 100 is disclosed, including a cup body 10 and a support frame 20; the cup body 10 is provided with a receiving chamber 101, a feed port 102 and a discharge port 103; from top to bottom, the feed port 102, the receiving chamber 101 and the discharge port 103 are arranged in sequence, and the feed port 102 is connected to the receiving chamber 101; the support frame 20 is connected to the edge of the discharge port 103, and the support frame 20 extends into the receiving chamber 101 through the discharge port 103; the support frame 20 is provided with a connecting groove 202, and the receiving chamber 101 is connected with the discharge port 103 via the connecting groove 202; the cavity wall of the receiving chamber 101 and the support frame 20 are used to support the filter paper 30, so that the bottom of the filter paper 30 can be located between the cavity wall of the receiving chamber 101 and the support frame 20.

[0036] Please refer to Figure 2 Through the above structure, generally, the filter paper 30 used for filtering coffee has a circular sheet structure. During use, the filter paper 30 is folded into a cone shape, and then the tip of the conical filter paper 30 is pressed into the conical space surrounded by the filter paper 30, so that the tip of the filter paper 30 extends into the space surrounded by the filter paper 30, and the outer surface of the filter paper 30 is surrounded to form a truncated cone shape; then, the filter paper 30 is placed in the coffee filter cup 100, and the circular end surface with a smaller area of ​​the filter paper 30 is placed at the discharge port 103, the support frame 20 contacts and supports the concave tip of the filter paper 30, and the cavity wall of the receiving cavity 101 contacts and supports the outer surface of the filter paper 30.

[0037] Then, coffee bean powder 40 is placed in the space enclosed by the filter paper 30, and the coffee bean powder 40 is accumulated at the bottom of the filter paper 30; the tip of the filter paper 30 is concave, so that the cross-sectional area of ​​the bottom of the filter paper 30 is larger, the height of the accumulated coffee bean powder 40 is lower, and the surface area of ​​the accumulated coffee bean powder 40 is larger. At the same time, the contact area between the coffee bean powder 40 and the inner surface of the filter paper 30 is also larger.

[0038] Subsequently, water is injected into the receiving chamber 101 through the feed port 102, and the water flows into the space surrounded by the filter paper 30 and mixes with the coffee bean powder 40; the surface area of ​​the accumulated coffee bean powder 40 is larger, so that the coffee bean powder 40 can be dissolved into the water faster and more evenly; the contact area between the coffee bean powder 40 and the inner surface of the filter paper 30 is larger, so that the concentrated coffee formed by the mixture of water and coffee bean powder 40 can more easily pass through the bottom of the filter paper 30, and the filter paper 30 can better filter the concentrated coffee, thereby improving the taste and flavor of the coffee.

[0039] Specifically, in this embodiment, the cup body 10 and the support frame 20 can be connected to each other by an integrated molding method; the cup body 10 has a hollow truncated cone structure, the top area of ​​the cup body 10 is larger than the bottom area, the top surface of the cup body 10 is open to form the feed port 102, and the bottom surface of the cup body 10 is downwardly open to form the discharge port 103; the support frame 20 also has a hollow truncated cone structure, the top area of ​​the support frame 20 is smaller than the bottom area, and the bottom of the support frame 20 is connected to the edge of the discharge port 103. When viewed from a top view, the side wall of the receiving cavity 101 can have an uneven annular wavy shape.

[0040] Each connecting groove 202 can be formed between two adjacent strip structures 22. The connecting groove 202 passes through the inner and outer surfaces of the support frame 20 so that the accommodating cavity 101 is connected with the discharge port 103 through the connecting groove 202. The upper end of the connecting groove 202 extends to the upper surface of the support frame 20. There are multiple connecting grooves 202, and all the connecting grooves 202 are evenly arranged around the outer surface of the support frame 20.

[0041] In other embodiments, the cup body 10 and the support frame 20 can be connected in other ways, such as gluing between the cup body 10 and the support frame 20; the cup body 10 can also have other structures, such as a hollow cylinder; the support frame 20 can also have other structures, such as a hollow cone; the connecting groove 202 can also have other shapes, such as a circular groove or a triangular groove.

[0042] In some embodiments, the receiving cavity 101 has a truncated cone-shaped structure, and the support frame 20 has a truncated cone-shaped structure; from top to bottom, the cross-sectional area of ​​the receiving cavity 101 gradually decreases, and the cross-sectional area of ​​the truncated cone surrounded by the support frame 20 gradually increases; the side surface of the support frame 20 facing the cavity wall of the receiving cavity 101 is used to support the filter paper 30.

[0043] Through the above structure, both the receiving chamber 101 and the support frame 20 have a truncated cone-shaped structure. The outer surface of the folded filter paper 30 is truncated cone-shaped, making it easier for the outer surface of the filter paper 30 to fit the cavity wall of the receiving chamber 101, and thus the cavity wall of the receiving chamber 101 can provide better support for the outer surface of the filter paper 30. At the same time, the concave tip of the filter paper 30 is conical and can fit the outer side of the support frame 20; thus, the support frame 20 can provide better support for the concave tip of the filter paper 30. In summary, the filter paper 30 can be placed more stably in the receiving chamber 101.

[0044] Specifically, in this embodiment, the height of the cup body 10 is greater than the height of the support frame 20 ; in other embodiments, the height of the support frame 20 may also be greater than or equal to the height of the cup body 10 .

[0045] In some embodiments, the degree of inclination of the generatrix of the receiving cavity 101 is the same as the degree of inclination of the generatrix of the truncated cone formed by the support frame 20 .

[0046] Through the above structure, the circular filter paper 30 is folded into a cone shape, and then the tip of the cone is pressed inward, so that the tip of the cone is concave, and the outer surface of the filter paper 30 is surrounded by a truncated cone; the inclination degree of the generatrix formed by the outer surface of the filter paper 30 is the same as the inclination degree of the generatrix of the tip of the filter paper 30. Correspondingly, the inclination degree of the generatrix of the accommodating cavity 101 is the same as the inclination degree of the generatrix of the truncated cone surrounded by the support frame 20. The cavity wall of the accommodating cavity 101 can fit with the outer surface of the filter paper 30, and at the same time, the concave tip of the filter paper 30 can fit with the support frame 20; so that the filter paper 30 can be placed more stably in the coffee filter cup 100.

[0047] Specifically, in other embodiments, the degree of inclination of the busbar of the receiving cavity 101 is different from the degree of inclination of the busbar of the truncated cone formed by the support frame 20. Correspondingly, the filter paper 30 can be made into a specific shape so that the outer surface of the filter paper 30 can fit the cavity wall of the receiving cavity 101, and at the same time, the concave tip portion of the filter paper 30 can fit the support frame 20.

[0048] In some embodiments, the connecting groove 202 is strip-shaped, the lower end of the connecting groove 202 is located at the discharge port 103, and the upper end of the connecting groove 202 passes through the top of the support frame 20; there are multiple connecting grooves 202, and all connecting grooves 202 are evenly distributed circumferentially around the central axis of the support frame 20; the connecting groove 202 is straight-line, and the central axis of the connecting groove 202 is staggered with the central axis of the support frame 20.

[0049] Through the above structure, all the connecting grooves 202 are evenly distributed circumferentially around the central axis of the support frame 20, so that the espresso formed by the mixture of water and coffee beans can flow out evenly through the edge of the discharge port 103, thereby increasing the flow rate of the espresso; at the same time, the espresso can pass through various places on the bottom of the filter paper 30 more evenly, thereby improving the filtering effect of the filter paper 30 on the espresso.

[0050] Specifically, in this embodiment, the support frame 20 includes a plurality of inclined strip structures 22, the strip structures 22 are evenly arranged around the central axis of the receiving cavity 101, and the bottom end of the strip structure 22 is connected to the edge of the discharge port 103, and the top end of the strip structure 22 extends in the direction of extending into the receiving cavity 101, so that the strip structure 22 is inclined, and the central axis of the strip structure 22 does not intersect with the central axis of the receiving cavity 101, and a connecting groove 202 is formed between two adjacent strip structures 22; so that the upper end of the connecting groove 202 passes through the top of the support frame 20, and the central axis of the connecting groove 202 is staggered with the central axis of the support frame 20.

[0051] Furthermore, the end faces of the strip structures 22 are curved, so that the side surfaces of the strip structures 22 facing the wall of the receiving cavity 101 are smooth and curved. This increases the contact area between the concave tip of the filter paper 30 and the support frame 20, allowing the support frame 20 to better support the concave tip of the filter paper 30. From top to bottom, the cross-sectional area of ​​the strip structures 22 gradually increases, so that the gaps between adjacent strip structures 22 are linear, i.e., the connecting grooves 202 are linear.

[0052] In other embodiments, the communicating groove 202 may also be in other shapes, such as an arc shape; the strip structure 22 may also be in other shapes, such as an inclined cylinder.

[0053] Please refer to Figure 3 In some embodiments, a plurality of guide grooves 104 are provided on the side wall of the receiving cavity 101, the upper end of the guide groove 104 is connected to the feed port 102, and the lower end of the guide groove 104 faces the discharge port 103, and all the guide grooves 104 are evenly distributed circumferentially around the central axis of the receiving cavity 101; the cavity wall of the guide groove 104 is used to support the filter paper 30.

[0054] Through the above structure, when the filter paper 30 is placed in the receiving chamber 101, the outer surface of the filter paper 30 can fit the groove wall of the guide groove 104, so that the outer surface of the filter paper 30 is annular and wavy when viewed from above; when water is poured into one side of the filter paper 30, the water can flow to the bottom of the filter paper 30 through the guide groove 104. The guide groove 104 guides the water so that the water has a greater impact force when it contacts the coffee bean powder 40 at the bottom of the filter paper 30, and the water can flow into various parts of the coffee bean powder 40 faster, thereby increasing the contact area between the coffee bean powder 40 and the water, thereby increasing the dissolution rate of the coffee bean powder 40 in the water.

[0055] Specifically, in this embodiment, when viewed from above, the opening at the top of the guide groove 104 is similar to a triangle; in other embodiments, when viewed from above, the opening at the top of the guide groove 104 can also be other shapes, such as a semicircle.

[0056] In some embodiments, the guide groove 104 is strip-shaped, and the central axes of the guide grooves 104 are staggered with each other.

[0057] With the above structure, when water is poured into the guide groove 104, the guide groove 104 can diagonally guide the water in the filter paper 30, so that the water can flow obliquely downward. When the water contacts the coffee bean powder 40 at the bottom of the filter paper 30, it continues to rotate around the central axis of the receiving chamber 101 due to inertia, generating a large vortex. The vortex can drive the coffee bean powder 40 to move in the water, thereby increasing the contact area between the coffee bean powder 40 and the water, so that the coffee bean powder 40 can be more evenly dissolved in the water.

[0058] Specifically, in this embodiment, the guide groove 104 is linear, and the width of the guide groove 104 gradually decreases from top to bottom. In other embodiments, the guide groove 104 can also be a pneumatic structure, such as an arc shape.

[0059] In some embodiments, the cup body 10 is further provided with an air guide groove 105 , which passes through the outer surface of the cup body 10 , and the receiving cavity 101 is connected to the outside through the air guide groove 105 .

[0060] Through the above structure, some gases, such as carbon dioxide, are generated during the dissolution of coffee bean powder 40 in water. These gases will affect the taste of the coffee. When water is injected into the filter paper 30, the water will generate a vortex. The flow rate of water in the filter paper 30 is faster, and the air pressure outside the filter paper 30 will be greater than the air pressure inside the filter paper 30. Under the action of pressure and centrifugal force, the gas in the water will pass through the filter paper 30 through the side surface of the filter paper 30, and then the gas will flow out of the cup body 10 through the air guide groove 105.

[0061] Specifically, in this embodiment, the air guide groove 105 is opened on the side groove wall of the guide groove 104, and the top of the cup body 10 is a strip-shaped wave structure, so that there is a distance between the upper end of the air guide groove 105 and the feed port 102; from top to bottom, the width of the air guide groove 105 gradually decreases.

[0062] In other embodiments, the air guiding groove 105 may also be directly opened on the side wall of the receiving cavity 101 , or the air guiding groove 105 may also pass through the top of the cup body 10 .

[0063] In some embodiments, each air guide groove 105 is connected to a corresponding air guide groove 104 , and the air guide groove 104 is located between the receiving cavity 101 and the corresponding air guide groove 105 , and the receiving cavity 101 is connected to the outside world through the air guide groove 104 and the air guide groove 105 in sequence.

[0064] Through the above structure, the guide grooves 104 are evenly distributed around the accommodating cavity 101, and each air guide groove 105 is connected to a corresponding air guide groove 104, so that the air guide grooves 105 are also evenly distributed around the accommodating cavity 101, and the distance between two adjacent air guide grooves 105 is smaller, so that the gas in the water in the filter paper 30 can be more easily discharged through the air guide grooves 105.

[0065] Specifically, the number of air guide grooves 105 is equal to the number of flow guide grooves 104, and thus each air guide groove 105 can correspond to one flow guide groove 104; the concentrated coffee in the filter paper 30 flows out of the filter paper through the bottom of the filter paper 30 under the action of liquid pressure, and the height of the bottom of the air guide groove 105 is greater than the height of the bottom of the connecting groove 202, so that the connecting groove 202 can be located at the bottom of the filter paper 30, and the concentrated coffee can all flow into the discharge port 103 through the connecting groove 202.

[0066] Please refer to Figure 4 In some embodiments, the cup body 10 includes a support wall 12, which is used to support the filter paper 30. The support wall 12 is arranged on the cavity wall of the receiving cavity 101. The support wall 12 is located at the lower part of the cup body 10. The support wall 12 is arranged around the central axis of the receiving cavity 101. The lower side of the support wall 12 faces the discharge port 103, and the upper side of the support wall 12 faces the feed port 102.

[0067] Through the above structure, the bottom of the outer side surface of the filter paper 30 can abut against the support wall 12 , and then the support wall 12 can support the filter paper 30 , so that the filter paper 30 can be placed more stably in the receiving cavity 101 .

[0068] Specifically, when viewed from above, the support wall 12 is a smooth annular structure, which allows the support wall 12 to have a larger contact area with the outer surface of the filter paper 30. In this embodiment, the upper side of the support wall 12 is wavy; in other embodiments, the upper side of the support wall 12 can also have other shapes, such as a flat circle.

[0069] In some embodiments, the upper side of the support wall 12 is wavy, and the upper side of the support wall 12 includes a peak section 122 and a trough section 124. The peak section 122 and the trough section 124 are alternately arranged, and each trough section 124 is located below a corresponding guide groove 104, and each peak section 122 is located between two adjacent guide grooves 104.

[0070] Through the above structure, the peak section 122 can extend between two adjacent guide grooves 104, so that the height of the support wall 12 can be higher, and the support wall 12 can support the outer surface of the filter paper 30 more stably.

[0071] Specifically, the width of the bottom of the guide groove 104 is the same as the distance between two adjacent guide grooves 104 , so that the width of the peak section 122 is the same as the width of the trough section 124 .

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Under the idea of ​​the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above.
