Description

Technical Field

[0001] This utility model relates to the field of coffee brewing devices, and in particular to a coffee filter cup and a coffee brewing device. Background Technology

[0002] Existing coffee filters typically have protruding ribs or grooves on their inner walls, especially where they contact the filter paper. These ribs or grooves create channels between the filter paper and the filter. When brewing coffee grounds, due to the bypass effect, the water flows out too quickly through these channels, resulting in uncooked coffee grounds, weak flavor, and low extraction rate. Therefore, existing coffee filters suffer from the problem of rapid water extraction and low coffee extraction rate during coffee brewing. Utility Model Content

[0003] The main technical problem solved by this utility model embodiment is to provide a coffee filter cup and coffee brewing device, which aims to solve the problem of rapid coffee extraction while ensuring the extraction rate of coffee liquid.

[0004] To solve the above-mentioned technical problems, the present invention provides a coffee filter cup, wherein the coffee filter cup has an inlet and an outlet at both ends along the vertical direction; the outer wall of the coffee filter cup has a snap-fit ​​part; the inner wall of the outlet has a flow channel; the outlet is also provided with a straw, and the straw is connected to the outlet.

[0005] Optionally, the drainage channel satisfies:

[0006]

[0007] Where h1 is the length of the flow channel in the vertical direction, and h2 is the length of the coffee filter cup in the vertical direction.

[0008] Optionally, multiple flow channels are provided, and the multiple flow channels are arranged at intervals along the circumference of the coffee filter cup.

[0009] Optionally, all drainage channels can be of equal length.

[0010] Optionally, the lengths of the drainage channels are not necessarily equal.

[0011] Optionally, the plurality of the flow channels have two or more lengths, and the flow channels of different lengths are arranged sequentially along the circumference of the coffee filter cup.

[0012] Another technical solution adopted by this utility model is: providing a coffee brewing device, including: a support and a coffee filter cup as described in any of the above; the support is provided with a mating part, and the mating part is correspondingly arranged with the snap-fit ​​part to fix the coffee filter cup to the support.

[0013] Optionally, the snap-fit ​​portion is a groove, and the mating portion is a protrusion.

[0014] Optionally, the snap-fit ​​portion is a protrusion, and the mating portion is a groove.

[0015] The beneficial effects of this utility model embodiment are as follows: Unlike existing technologies, this utility model provides a coffee filter cup with an inlet and an outlet at both ends along the vertical direction. The outer wall of the coffee filter cup has a snap-fit ​​part, allowing it to be detachably installed on the support of a coffee brewing device. The inner wall of the coffee filter cup has a flow channel near the outlet, located below the coffee grounds layer. The cup wall above the flow channel is completely flush with the filter paper, preventing water separation. This ensures that all water must pass through the coffee grounds layer to be extracted, achieving the desired coffee brewing effect. Simultaneously, the flow channel and straw at the outlet achieve both the coffee brewing effect and ensure timely extraction of the coffee liquid. Compared to existing coffee filter cups, the coffee filter cup provided in this application simultaneously addresses the issues of coffee flavor and brewing efficiency, enabling the production of a better-flavored coffee liquid in a shorter time.

[0028] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0030] Please see Figure 1 and Figure 2 This utility model provides a coffee filter cup 100 for filtering coffee liquid. The coffee filter cup 100 is conical, with an inlet 10 at one end along the vertical direction V and an outlet 20 at the other end along the vertical direction V. The size of the outlet 20 is smaller than the size of the inlet 10. The outer wall of the coffee filter cup 100 has a snap-fit ​​part 40, which allows the coffee filter cup 100 to be detachably installed on the bracket of a coffee brewing device.

[0031] The inner wall of the coffee filter cup 100 is provided with a flow channel 30, which is located below the coffee grounds layer. The coffee grounds layer is in complete contact with the filter cup wall and the filter paper, eliminating the possibility of water separation during brewing, thus achieving the desired brewing effect for the coffee grounds. The flow channel 30 is used to guide the brewed coffee liquid to discharge it out of the coffee filter cup 100. At the same time, a straw 300 is provided at the outlet, which is connected to the outlet 20. When the coffee liquid enters the straw 300 through the flow channel 30 and is discharged, the straw 300 is under negative pressure, which can increase the speed of coffee liquid discharge. Compared with the existing technology where the height of the vertical flow channel 30 is approximately equal to the height of the coffee filter cup 100, the brewing water separates out from the flow channel 30 before the coffee grounds have been fully brewed, resulting in a low coffee extraction rate. Therefore, the coffee filter cup 100 provided in this application can simultaneously address the issues of coffee flavor and production efficiency, enabling the production of coffee with better flavor in a shorter time.

[0032] Please see Figure 3 or Figure 4 In some embodiments, the drainage channel 30 satisfies equation (1):

[0033]

[0034] Where h1 is the length of the flow channel 30 along the vertical direction V, and h2 is the length of the coffee filter cup 100 along the vertical direction V. Equation (1) reflects the proportion of the length of the flow channel 30 in the vertical direction V. By controlling the length of the flow channel 30, the flavor of the coffee liquid and the efficiency of coffee production can be precisely controlled.

[0035] Furthermore, in some embodiments, the drainage channel 30 satisfies equation (2):

[0036]

[0037] When the length ratio of the flow channel 30 in the vertical direction V satisfies equation (2), a more precise balance can be achieved between the flavor of the coffee liquid and the production efficiency of the coffee liquid.

[0038] In some preferred embodiments, The ratio is 0.15 or 0.16 or 0.17 or 0.18 or 0.25 or 0.26 or 0.27 or 0.28 or 0.35 or 0.36 or 0.37 or 0.38.

[0039] Please see Figure 2 and Figure 3In some embodiments, the flow channel 30 is arranged from the outlet 20 toward the inlet 10, that is, the flow channel 30 is straight. Compared with a non-straight flow channel 30, the straight flow channel 30 can increase the speed at which coffee liquid is discharged from the coffee filter cup 100, thereby taking into account both the flavor of the coffee liquid and the production efficiency.

[0040] Please see Figure 2 In some embodiments, multiple flow channels 30 are provided, and the multiple flow channels 30 are arranged at intervals along the circumference of the coffee filter cup 100. Since the length of the flow channels 30 is limited, and the length of the flow channels 30 has a significant impact on the speed at which coffee liquid is discharged from the coffee filter cup 100, providing multiple flow channels 30 can appropriately increase the speed of coffee liquid discharge, thereby taking into account both the flavor of the coffee liquid and the production efficiency.

[0041] Further, please refer to Figure 3 In some embodiments, multiple drainage channels 30 are provided, and the lengths of each drainage channel 30 are exactly equal.

[0042] Further, please refer to Figure 4 In some embodiments, multiple drainage channels 30 are provided, and the lengths of each drainage channel 30 are not exactly equal. By setting drainage channels 30 of unequal lengths, the speed at which coffee liquid is discharged from the coffee filter cup 100 can be precisely controlled.

[0043] Furthermore, in some embodiments, there are multiple drainage channels 30, each with a length that is not exactly equal, and the multiple drainage channels 30 have two or more lengths, with drainage channels 30 of different lengths arranged sequentially along the circumference of the coffee filter cup 100.

[0044] For example, multiple drainage channels 30 are provided, and the multiple drainage channels 30 have two lengths, that is, a portion of the drainage channels 30 have a length of h11, and another portion of the drainage channels 30 have a length of h12. The drainage channels 30 with a length of h11 and the drainage channels 30 with a length of h12 are arranged sequentially, that is, the multiple drainage channels 30 are arranged in the order A, B, A, B, A, B, ..., where A represents the drainage channel 30 with a length of h11 and B represents the drainage channel 30 with a length of h12.

[0045] For example, multiple drainage channels 30 are provided, and these drainage channels 30 have three lengths: a portion of the drainage channels 30 have a length of h13, another portion have a length of h14, and the remaining drainage channels 30 have a length of h15. The drainage channels 30 with a length of h13, h14, and h15 are arranged sequentially. That is, the multiple drainage channels 30 are arranged in the order C, D, E, C, D, E, C, D, E, ..., where C represents the drainage channel 30 with a length of h13, D represents the drainage channel 30 with a length of h14, and E represents the drainage channel 30 with a length of h15.

[0046] For example, multiple drainage channels 30 are provided, and the multiple drainage channels 30 have more than four different lengths, with drainage channels 30 of different lengths arranged sequentially.

[0047] In summary, this utility model provides a coffee filter cup 100. The coffee filter cup 100 has an inlet 10 and an outlet 20 at both ends along the vertical direction V. The outer wall of the coffee filter cup 100 has a snap-fit ​​portion 40, allowing the coffee filter cup 100 to be detachably mounted on the support of a coffee brewing device. A flow channel 30 is provided at the outlet 20. By combining the flow channel 30 at the outlet with a straw 300, the time it takes for the coffee liquid to separate from the coffee filter cup 100 during brewing can be controlled, while also ensuring the flavor of the coffee liquid. Compared to existing coffee filter cups 100, the coffee filter cup 100 provided in this application can simultaneously address the issues of coffee flavor and brewing efficiency, enabling the production of coffee liquid with superior flavor in a shorter time.

[0048] Please see Figure 5 and Figure 6 This utility model also provides a coffee brewing device 1000, which includes a support 200 and the aforementioned coffee filter cup 100. The support 200 provides support for the coffee filter cup 100 to fix it in place. The support 200 has a mating part 200a, which corresponds to a snap-fit ​​part 40 to fix the coffee filter cup 100 to the support 200. The connection method between the mating part 200a and the snap-fit ​​part 40 includes, but is not limited to, snap-fit, magnetic attraction, etc.

[0049] Please refer to the following: Figure 1 , Figure 5 and Figure 6 In some embodiments, the snap-fit ​​portion 40 of the coffee filter cup 100 is a groove, and the mating portion 200a is a protrusion. During installation, the protrusion snaps into the groove to fix the coffee filter cup 100 to the bracket 200.

[0050] In some embodiments, the snap-fit ​​portion 40 of the coffee filter cup 100 is a protrusion, and the mating portion 200a is a groove. During installation, the protrusion snaps into the groove to fix the coffee filter cup 100 to the bracket 200.
