Description

Modular coffee filter cup kit and coffee filtering device Technical Field

[0001] The present application relates to a coffee filtering device, and more particularly to a modular coffee filter cup kit. Background Art

[0002] Pour-over coffee can be prepared in two methods: drip and immersion. Drip coffee intensifies the coffee's flavor complexity, often highlighting delicate flavors and aromas. This allows the water to extract the coffee's oils and solubles as it passes through the grounds, resulting in a clearer flavor profile. Depending on the flavor profile you want to emphasize, different pour-over equipment comes into play, allowing you to achieve different flavor profiles even with the same beans.

[0003] A coffee filter is a device used to extract and filter coffee. Its primary function is to support the filter paper, allowing it to effectively separate the coffee grounds from the liquid. The soaking time during the coffee filtration process influences the flavor and taste of the resulting coffee. The shape and number of the raised patterns on the inner wall of the coffee filter, as well as the size and shape of the holes in the holder, determine the filtration speed.

[0004] Existing coffee filters and cup holders are mostly integrated, and they only accept one type of filter paper depending on the cup size, making them inflexible. Due to their integrated design, traditional coffee filters also produce a relatively fixed flavor and a monotonous taste. Furthermore, pour-over coffee is a slow-paced lifestyle, and a monotonous, fixed coffee filter lacks the enjoyment of using it.

It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0088] The application content is further explained below through description of embodiments in conjunction with the accompanying drawings.

[0089] In a first aspect of the present embodiment, a modular coffee filter cup kit is provided. FIG1 is a schematic structural diagram of the coffee filter cup kit, which includes:

[0090] A coffee filter cup 1 has a container space with an upward opening, a plurality of flow-guiding structures inside the cup body of the coffee filter cup 1, and a through hole at the bottom, wherein the flow-guiding structures are used to increase the water flow rate.

[0091] The guide structure includes: convex ribs and concave ribs; one convex rib is composed of two convex lines, and the convex rib can increase the space between the filter paper 2 and the coffee filter cup 1, thereby increasing the exhaust effect and improving the water flow rate to a certain extent.

[0092] One of the concave ribs is composed of two depressions, and the concave rib is used to reduce the space between the filter paper and the coffee filter cup, so that the filter paper 2 and the wall of the coffee filter cup 1 fit better. Therefore, when using the coffee filter cup kit in this embodiment to brew coffee, the bypass water is reduced, the contact time between water and coffee powder is increased, and the water flow rate is slowed down.

[0093] Bypass water refers to water that does not or does not completely pass through the coffee grounds during coffee brewing. The depth of the ribs can control the contact time between the water and the coffee grounds. By increasing the bypass water, the water flow rate can be adjusted. Specifically, when the ribs are shallower, the coffee filter cup 1 fits more tightly with the filter paper 2. The ribs divert and store water, i.e., the bypass water is poor, resulting in a slower water flow and more complete extraction, but also prone to over-extraction. When the ribs are deeper, the coffee filter cup 1 fits less tightly with the filter paper 2. The ribs divert and store water, i.e., the bypass water is stronger, resulting in a faster water flow rate, but also prone to under-extraction of the powder bed in the lower half.

[0094] Specifically, the ribs enhance degassing. They create airflow channels between the filter paper 2 and the coffee filter cup 1, preventing the mutual repulsion between air and water that could affect extraction efficiency. This is especially true during the initial steaming phase of brewing, when a significant amount of air is released from the coffee. If this air is not properly vented, it will push upward through the coffee grounds bed from the lower filter opening. This upward movement allows cold air to enter, reducing extraction efficiency. Therefore, shallower rib depths result in poorer degassing, while shallower rib depths result in stronger degassing.

[0095] A filter paper 2 is placed inside the content space of the coffee filter cup 1. The filter paper 2 can be fan-shaped, cone-shaped or corrugated.

[0096] A cup holder 3 has a through hole, and the coffee filter cup 1 is placed on the cup holder 3. The filter paper 2 is placed in the volume of the coffee filter cup 1, and different types of coffee filter cups 1 and cup holders 3 can be used together to produce coffee with different flavors.

[0097] Specifically, the coffee filter cup 1 is preferably made of ceramic material, which is stable and corrosion-resistant, thus preventing any degradation of coffee quality. Different coffee filter cup bodies can accommodate fan-shaped, conical, or corrugated filter paper 2. During use, the filter paper 2 is placed in a suitable coffee filter cup 1 and pre-moistened with hot water to ensure a snug fit within the cup body. This also allows for warming and cleaning the cup. Furthermore, the design of this application does not alter the strength of the filter paper.

[0098] The coffee filter cup 1 has ribs of varying shapes and numbers on its inner wall, and is paired with a cup holder 3 having holes of varying sizes and shapes. When using a cup holder 3 with smaller holes, the water flows more slowly, soaking the coffee grounds for a longer time. When using a cup holder with larger holes, the water flows more quickly, soaking the coffee grounds for a shorter time. Thus, by changing the combination of the coffee filter cup 1 and cup holder 3, the user can adjust the time the water soaks the coffee grounds and the water flow rate during the filtration process, resulting in coffee with varying flavors and tastes.

[0099] Specifically, the cup holder 3 can include a cup groove for retaining the coffee filter cup 1. In this case, the connection between the coffee filter cup 1 and the cup holder 3, through the cup groove design with a close fit and tight tolerances, forms a tight fit. This ensures that during the pour-over coffee process, coffee liquid does not overflow from the connection between the coffee filter cup 1 and the cup holder 3, causing waste and dirt. The cup holder 3 can also be devoid of a cup groove. The coffee filter cup 1 can be stacked on the cup holder 3 and rotated about its longitudinal axis. Furthermore, the stacking assembly method of the present application is simple, intuitive, and easy to use.

[0100] In one embodiment, a coffee filter cup 11 as shown in Figures 2 and 3 is also provided, wherein the ribs include: vertical ribs and transverse annular ribs; one end of the vertical rib is connected to the upper edge of the coffee filter cup, and the other end is connected to the bottom of the coffee filter cup; the transverse annular rib is located in the lower middle side of the interior of the coffee filter cup.

[0101] This embodiment utilizes twelve vertical ribs to increase the water flow velocity, directing it vertically and evenly through the coffee bed, achieving uniform extraction and preventing over-extraction. The coffee filter cup 11 also features three transverse annular ribs on the lower center side of the cup body. When using the coffee filter cup 11, coffee grounds are poured into the cup, forming a coffee bed. The three transverse annular ribs, located in the lower center of the coffee bed, extend the water flow path and prevent insufficient contact time between the coffee grounds and water due to excessive water flow through the vertical ribs.

[0102] In addition, the horizontal and vertical staggering of the vertical ribs and the transverse annular ribs in this embodiment can cause disturbances in the water flow along the wall, thereby increasing the extraction efficiency in the middle and lower part of the powder bed.

[0103] The raised ribs can increase the space between the filter paper and the filter cup, thereby enhancing the degassing effect and increasing the water flow rate to a certain extent. Using the coffee filter cup 11, the brewing flow rate is faster, which can enhance the diverse layered flavor of coffee and obtain a relatively refreshing taste.

[0104] The coffee filter cup 11 of this embodiment can be adapted to the corrugated filter paper 21 and the conical filter paper 23, and is matched with the first cup holder 31. The first cup holder 31 is the cup holder with the largest through-hole area. The combination can achieve the fastest filtering speed, highlight the coffee flavor layers, and maintain a refreshing taste.

[0105] The coffee filter cup 11 of this embodiment can be adapted to the corrugated filter paper 21 and matched with the second cup holder 32. The second cup holder 32 has the second largest through-hole area. The combination can achieve uniform extraction, a faster flow rate in the filter cup, highlighting the balanced flavor of the coffee and maintaining a refreshing taste.

[0106] The coffee filter cup 11 of this embodiment can be paired with a third cup holder 33, which has the third largest through-hole area. Using conical filter paper 23 achieves the same effect as using the second cup holder 32, enabling faster filtration, highlighting the layers of coffee flavor, and maintaining a refreshing taste. Using corrugated filter paper creates a thinner layer of coffee grounds, enabling even extraction. The flow rate of the coffee filter cup 11 is reduced compared to the previous combination, resulting in a more balanced coffee flavor and a mellower mouthfeel.

[0107] The coffee filter cup 11 of this embodiment can be used with a fourth cup holder 34. The fourth cup holder 34 is the cup holder with the smallest through-hole area. When used with the corrugated filter paper 21, the coffee powder layer is thinner, which can achieve uniform extraction, a faster flow rate in the filter cup, a balanced coffee flavor, and an improved taste.

[0108] In one embodiment, a coffee filter cup 12 is provided as shown in Figures 4 and 5. The upper inner side of the coffee filter cup 12 has a buffer belt, twelve vertical ribs are evenly arranged below the buffer belt, and three transverse annular ribs are arranged at the lower part of the inner body of the coffee filter cup.

[0109] Specifically, in this embodiment, the coffee filter cup 12 may be 6.66 cm high, the buffer band may be about 2.2 cm wide, and the vertical ribs may extend from the bottom of the filter cup to a height of 5 cm on the cup wall.

[0110] The buffer zone is a smooth cup wall, and the buffer zone has a higher fit with the filter paper 2. When brewing at a high water level (mostly a single-knife flow), the dragging ability of the water is weakened, and the taste of the produced coffee is more rounded and mellow than that of the above-mentioned coffee filter cup 11.

[0111] The coffee filter cup 12 of this embodiment can be adapted to the first cup holder 31 and the corrugated and conical filter papers 23. The first cup holder 31 is the cup holder with the largest through-hole area. When used together, faster filtering can be achieved, highlighting the coffee flavor layers and maintaining a refreshing taste.

[0112] The coffee filter cup 12 of this embodiment can be adapted to the corrugated filter paper 21 and matched with the second cup holder 32. The second cup holder 32 is the cup holder with the second largest through-hole area. The combination can achieve uniform extraction. The flow rate of the coffee filter cup 12 is faster, highlighting the balanced flavor of the coffee and maintaining a refreshing taste.

[0113] The coffee filter cup 12 of this embodiment can be paired with a third cup holder 33, which has the third largest through-hole area. Using conical filter paper 23 achieves the same effect as using the first cup holder 31, achieving a moderate filtration rate, highlighting the layers of coffee flavor, and maintaining a refreshing taste. Using corrugated filter paper 21 creates a thinner layer of coffee grounds, enabling uniform extraction. The flow rate in the filter cup is lower than using conical filter paper 23, resulting in a more balanced coffee flavor and a mellow taste.

[0114] The coffee filter cup 11 of this embodiment can be used with a fourth cup holder 34. The fourth cup holder 34 is the cup holder with the smallest through-hole area. When used with the corrugated filter paper 21, the coffee powder layer is thinner, which can achieve uniform extraction. The flow rate of the coffee filter cup is moderate, the coffee flavor is balanced, and the taste is mellower.

[0115] In one embodiment, a coffee filter cup 13 is provided as shown in Figures 6 and 7 , wherein the ribs include: a dot matrix stripe and a guide groove. The dot matrix stripe is a raised line composed of a plurality of raised dots; the guide groove is a rounded concave guide groove formed by two of the raised lines; the guide grooves are spaced apart between the dot matrix stripes; one end of the dot matrix stripe is connected to the upper edge of the coffee filter cup, and the other end is connected to the bottom of the coffee filter cup; the guide groove extends from the middle of the coffee filter cup to the bottom of the coffee filter cup.

[0116] Specifically, the one lattice strip constitutes one convex line, the two convex lines constitute one convex rib, and the guide groove is arranged between each convex rib, that is, the guide groove is arranged at intervals between the lattice strips.

[0117] In this embodiment, twelve dot matrix strips consisting of convex dots are evenly arranged inside the coffee filter cup 13, and twelve guide grooves are arranged at intervals between the dot matrix strips. The guide grooves are rounded concave guide grooves, and the length of the guide grooves is half the length of the dot matrix strips. The guide grooves extend from the middle of the coffee filter cup 13 to the bottom of the coffee filter cup 13.

[0118] The twelve dot matrix strips formed by the convex dots can enhance the dispersed flow of the water flow, so that the water flow forms a wavy water flow path, thereby increasing the water flow path and improving the extraction efficiency.

[0119] Twelve rounded, concave guide grooves extend from the center of the cup to the bottom of the filter cup. These grooves accelerate water flow from the center bottom, reducing extraction efficiency and preventing over-extraction caused by accumulation of fine powder and excessive extraction from the lattice ribs. The coffee filter cup 13 of this embodiment offers a moderate brewing flow rate, diverse flavor profiles, and produces highly clean coffee.

[0120] The coffee filter cup 13 of this embodiment can be adapted to the corrugated and conical filter papers 23, and is matched with the first cup holder 31. The first cup holder 31 is the cup holder with the largest through-hole area. The combination can achieve faster filtering speed, highlight the coffee flavor layers, and maintain a refreshing taste.

[0121] The coffee filter cup 13 of this embodiment can be adapted to the corrugated filter paper 21 and matched with the second cup holder 32. The second cup holder 32 has the second largest through-hole area. The combination can achieve uniform extraction, and the flow rate of the coffee filter cup is moderate, highlighting the balanced flavor of the coffee and maintaining a refreshing taste.

[0122] The coffee filter cup 13 of this embodiment can be paired with a third cup holder 33, which has the third largest through-hole area. Using conical filter paper 23 achieves the same effect as using the second cup holder 32, enabling a lower filtration rate, highlighting the layers of coffee flavor and maintaining a refreshing taste. Using corrugated filter paper 21 creates a thinner layer of coffee grounds, enabling even extraction. The flow rate in the filter cup is slightly lower than using the conical filter paper 23, resulting in a more balanced coffee flavor and a mellow taste.

[0123] The coffee filter cup 13 of this embodiment can be used with a fourth cup holder 34. The fourth cup holder 34 is the cup holder with the smallest through-hole area. When used with the corrugated filter paper 21, the coffee powder layer is thinner, which can achieve uniform extraction. The flow rate of the coffee filter cup is slower, the coffee flavor is balanced, and the taste is mellower.

[0124] In one embodiment, a coffee filter cup 14 is provided as shown in Figures 8 and 9, wherein the ribs include a first rib and a second rib. The first rib and the second rib are both right-angled guide grooves formed by two convex lines; the right-angled guide grooves have a depth of 0.2 cm.

[0125] The first and second ribs are inclined in opposite directions; the extension lines of the first and second ribs are inclined at approximately a 45-degree angle. The first rib is connected to the upper edge of the coffee filter cup at the top, and the second rib is connected to the bottom of the coffee filter cup at the bottom. A buffer zone is provided between the first and second ribs.

[0126] Specifically, in this embodiment, the width of the buffer zone may be 1.1 cm. Four first ribs and four second ribs are provided.

[0127] The fewer ribs in this embodiment result in a slower flow rate. The design of the first and second ribs, tilted in opposite directions, directs the flow in different directions, extending the water path and creating a vortex-like agitation. A 1.1 cm buffer zone is retained between the first and second ribs, creating a gap between the filter paper and the cup body, creating an air vent and alleviating the overall slow flow rate caused by the ribs. The coffee filter cup 14 in this embodiment has a slower brewing rate, and the resulting coffee is similar to immersion extraction, with a richer taste.

[0128] The coffee filter cup 14 of this embodiment can be adapted to corrugated and conical filter papers 23, and is matched with a first cup holder 31. The first cup holder 31 is the cup holder with the largest through-hole area. The combination can achieve faster filtering speed, highlight the coffee flavor layers, and maintain a refreshing taste.

[0129] The coffee filter cup 14 of this embodiment can be adapted to the corrugated filter paper 21 and matched with the second cup holder 32. The second cup holder 32 has the second largest through-hole area. The combination can achieve uniform extraction, a moderate flow rate in the filter cup, highlighting the balanced flavor of the coffee and maintaining a refreshing taste.

[0130] The coffee filter cup 14 of this embodiment can be used with a third cup holder 33, which has the third largest through-hole area. Using a conical filter paper 23 achieves the same effect as the first cup holder 31, enabling a lower filtration rate, highlighting the layers of coffee flavor and maintaining a refreshing taste. Using corrugated filter paper 21 creates a thinner layer of coffee grounds, enabling even extraction. The flow rate of the coffee filter cup 14 is slightly lower than using the conical filter paper 23, resulting in a more balanced coffee flavor and a mellow taste.

[0131] The coffee filter cup 14 of this embodiment can be used with a fourth cup holder 34. The fourth cup holder 34 is the cup holder with the smallest through-hole area. When used with the corrugated filter paper 21, the coffee powder layer is thinner, which can achieve uniform extraction, a slower flow rate in the filter cup, a balanced coffee flavor, and an improved taste.

[0132] In one embodiment, a coffee filter cup 15 is provided as shown in Figures 10 and 11, wherein the ribs include: corrugated curved ribs; the corrugated curved ribs are uniformly arranged laterally throughout the entire cup body, thereby increasing the water flow path, causing disturbances in the water flow along the wall, and increasing extraction time and efficiency.

[0133] Specifically, the curved contours of the corrugated ribs create different impacts on the underlying coffee grounds at valleys and peaks. Peaks disperse the water flow, while valleys converge it. When the brewing water reaches the surface of the grounds, extraction tends toward immersion-style extraction. Brewing using the coffee filter 15 of this embodiment results in a slow flow rate, a balanced taste, and a high body.

[0134] The coffee filter cup 15 of this embodiment can be adapted to the corrugated and conical filter papers 23 and is matched with the first cup holder 31. The first cup holder 31 has the largest through-hole area and can achieve a moderate filtering speed, highlight the coffee flavor layers, and maintain a refreshing taste.

[0135] The coffee filter cup 15 of this embodiment can be adapted to the corrugated filter paper 21 and matched with the second cup holder 32. The second cup holder 32 has the second largest through-hole area. The combination can achieve uniform extraction. The flow rate of the coffee filter cup is slow, highlighting the balanced flavor of the coffee and maintaining a refreshing taste.

[0136] The coffee filter cup 15 of this embodiment can be paired with a third cup holder 33, which has the third largest through-hole area. Using conical filter paper 23 achieves the same effect as pairing the coffee filter cup 15 with the first cup holder 31, achieving a lower filtration rate, highlighting the layers of coffee flavor, and maintaining a refreshing taste. Using corrugated filter paper 21 creates a thinner layer of coffee grounds, enabling even extraction. The flow rate of the coffee filter cup 15 is slightly lower than using the conical filter paper 23 combination, resulting in a more balanced coffee flavor and a mellow taste.

[0137] The coffee filter cup 15 of this embodiment can be used with a fourth cup holder 34. The fourth cup holder 34 is the cup holder with the smallest through-hole area. When used with the corrugated filter paper 21, the coffee powder layer is thinner, which can achieve uniform extraction. The flow rate of the coffee filter cup 15 is slower, the coffee flavor is balanced, and the taste is mellower.

[0138] In one embodiment, a coffee filter cup 16 as shown in Figures 12 and 13 is also provided, wherein the ribs include: spiral ribs; one end of the spiral ribs is connected to the bottom of the coffee filter cup, and the other end is connected to the upper edge of the coffee filter cup, and the spiral ribs form an angle with the vertical direction.

[0139] This embodiment utilizes fifteen spiral ribs. This greater number of ribs provides enhanced flow guidance and a faster water flow rate. The spiral shape also extends the flow path, achieving a moderate flow rate. The ribs in this embodiment have a larger transverse surface area, allowing the filter paper to fit snugly against the ribs. This appropriately reduces drag on the water flow, increases contact time between the water and the coffee grounds, and improves extraction efficiency.

[0140] Specifically, when the water level is low or drops during brewing, the water flow will converge toward the center along the spiral ribs, creating a squeezing effect on the coffee grounds to a certain extent, promoting contact between the water and the coffee grounds and improving extraction efficiency. Coffee brewed using this embodiment of the coffee filter has a moderate brewing flow rate, rich flavor layers, and a relatively rounded taste.

[0141] The coffee filter cup 16 of this embodiment can be adapted to corrugated and conical filter papers 23, and is matched with a first cup holder 31. The first cup holder 31 is the cup holder with the largest through-hole area. The combination can achieve the fastest filtering speed, highlight the coffee flavor layers, and maintain a refreshing taste.

[0142] The coffee filter cup 16 of this embodiment can be adapted to the corrugated filter paper 21 and matched with the second cup holder 32. The second cup holder 32 has the second largest through-hole area. The combination can achieve uniform extraction. The coffee filter cup 16 has the fastest flow rate, highlighting the balanced flavor of the coffee and maintaining a refreshing taste.

[0143] The coffee filter cup 16 of this embodiment can be used with a third cup holder 33, which has the third largest through-hole area. Using conical filter paper 23 achieves the same effect as the first cup holder 31, enabling faster filtration, highlighting the layers of coffee flavor, and maintaining a refreshing taste. Using corrugated filter paper creates a thinner layer of coffee grounds, enabling even extraction. The flow rate of the coffee filter cup is slightly lower than using the conical filter paper 23, resulting in a more balanced coffee flavor and a mellow taste.

[0144] The coffee filter cup 16 of this embodiment can be used with a fourth cup holder 34. The fourth cup holder 34 is the cup holder with the smallest through-hole area. When used with the corrugated filter paper 21, the coffee powder layer is thinner, which can achieve uniform extraction. The coffee filter cup 16 has a faster flow rate, a balanced coffee flavor, and an improved taste.

[0145] In one embodiment, a coffee filter cup 17 is provided, as shown in Figures 14 and 15 . The ribs include teardrop-shaped ribs that are wide at the top and narrow at the bottom. Buffer zones are provided between the teardrop-shaped ribs and the bottom and top of the coffee filter cup, enhancing the degassing effect of the coffee filter cup 17. When brewing coffee, effective degassing is achieved when coffee grounds come into contact with water, thereby increasing extraction efficiency.

[0146] The coffee filter cup 17 has a fan-shaped body that is wide at the top and narrow at the bottom, and the through-hole at the bottom of the coffee filter cup 17 is in the shape of a straight line. This fan-shaped body, wide at the top and narrow at the bottom, with a straight line at the bottom, helps evenly distribute the coffee grounds and reduces accumulation. Furthermore, the narrow, straight-line through-hole structure at the bottom also helps concentrate the brewing water. The smaller filtration area at the bottom slows down the water flow. The coffee filter cup 17 has a smaller cup angle, longer sidewalls, and a shorter center distance from the cup wall, effectively increasing the contact time between the coffee powder and the water, improving extraction efficiency.

[0147] The coffee filter cup 17 of this embodiment can be adapted to fit the fan-shaped filter paper 22 and is matched with the first cup holder 31, which has the largest through-hole area. When used together, the coffee filter cup 17 has a slower flow rate and a richer coffee taste.

[0148] The coffee filter cup 17 of this embodiment can be adapted to the fan-shaped filter paper 22 and matched with the second cup holder 32. The second cup holder 32 is the cup holder with the second largest through-hole area. The combination can achieve uniform extraction, the flow rate of the coffee filter cup 17 is slow, and the coffee tastes mellow and rich.

[0149] In one embodiment, a coffee filter cup 18 is provided, as shown in Figures 16 and 17. The ribs of the coffee filter cup 18 include full-length teardrop-shaped ribs and half-length teardrop-shaped ribs. The teardrop-shaped ribs are wide at the top and narrow at the bottom. The half-length teardrop-shaped ribs are half the length of the full-length ribs, and the half-length ribs are spaced apart from the full-length ribs. A buffer zone is provided between each teardrop-shaped rib and the bottom and top edge of the coffee filter cup. This enhances the air venting effect of the coffee filter cup, ensuring effective air venting when coffee powder and water come into contact during brewing, thereby increasing extraction efficiency. The provision of buffer zones at both the top and bottom ensures that the top of the coffee filter cup has a smooth wall, which adheres more closely to the filter paper when water flows. This reduces the drag and air venting effects of the water flow, thus reducing the excessive water flow rate caused by high water pressure, thereby achieving a better brewing effect.

[0150] In addition, the half-length ribs reduce the height, appropriately reducing the diversion effect at high water levels and slowing down the water flow rate.

[0151] The coffee filter cup 18 of this embodiment can be used with the fan-shaped filter paper 22 and matched with the first cup holder 31. The first cup holder 31 is the cup holder with the largest through-hole area. The combination can achieve slower filtering and a mellower coffee taste.

[0152] The coffee filter cup 18 of this embodiment can be adapted to the fan-shaped filter paper 22 and matched with the second cup holder 32. The second cup holder 32 has the second largest through-hole area. The combination can achieve uniform extraction. The coffee filter cup 18 has the slowest flow rate and the coffee tastes mellow and rich.

[0153] In one embodiment, a first cup holder 31 is provided as shown in FIG. 18 . The cup holder 3 has a limiting structure, namely a cup groove, and a circular through hole is located in the center of the cup holder 3 .

[0154] For example, the cup holder can also be square, with the through hole located in the center of the cup holder and in a circular shape. The first cup holder 31 can be a cube with a side length of 5 cm, the diameter of the through hole can be 3 cm, and the hollow area can be about 7.06 cm. 2 The first cup holder 31 is the cup holder with the largest through-hole area, which can achieve the fastest filtering speed, highlight the coffee flavor layers, and maintain a refreshing taste.

[0155] In one embodiment, a second cup holder 32 is provided as shown in FIG19 . The cup holder 3 has a limiting structure, namely a cup groove, and the through hole has two symmetrical semi-annular through holes, with a linear through hole between the two semi-annular through holes, located in the center of the cup holder 3 .

[0156] For example, the cup holder can also be square, with two symmetrical semi-circular through holes, and a linear through hole between the two semi-circular through holes. The linear through hole can be 4 cm long and 0.5 cm wide; the semi-circular through hole can be 0.5 cm wide; the area of ​​the through hole is about 6.75 cm. 2 This cup holder has the second largest through-hole area, which can achieve uniform extraction and a faster flow rate. When using the second cup holder 32 to make coffee, the balanced flavor of the coffee can be highlighted and the taste can be kept fresh.

[0157] In one embodiment, a third cup holder 33 is provided as shown in FIG. 20 , wherein the through hole is located in the center of the cup holder and is in a cross star shape.

[0158] For example, the area of ​​the cross-star-shaped through hole may be 3.04 cm 2 The third cup holder 33 has the third largest through-hole area. When the third cup holder 33 is used to make coffee, the flow rate is moderate.

[0159] In one embodiment, a fourth cup holder 34 is provided as shown in FIG21 . The cup holder includes a first through hole and a second through hole. The first through hole is a plurality of arc-shaped through holes spaced apart from each other, and the second through hole is a cross-shaped through hole. The first through hole is an annular ring with a notch, and the second through hole is located in the center of the cup groove.

[0160] Specifically, the first through hole may be a plurality of arc-shaped through holes arranged at intervals; the second through hole may be a cross-shaped through hole, including a square through hole and fan-shaped through holes located at the four corners of the square through hole; the first through hole may be an annular ring with a notch; the second through hole is located in the center of the cup holder.
