Description

Technical Field

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

[0002] There are two methods for brewing hand-brewed coffee: drip coffee and immersion coffee. Drip coffee will enhance the complexity of the coffee flavor, often highlighting the delicate flavor and aroma, because drip coffee allows water to extract the oil and soluble substances of the coffee when passing through the powder, and can also highlight a clearer flavor. Depending on the flavor characteristics you want to emphasize, different hand-brewed utensils come into play at this time, even if you brew the same coffee beans, there will be different flavors.

[0003] The coffee filter is a device for extracting and filtering coffee. Its main function is to hold the filter paper so that the filter paper can effectively separate the coffee grounds from the coffee liquid. The soaking time of the coffee filtering process affects the flavor and taste of the coffee. The shape and number of the protruding lines on the inner wall of the coffee filter cup, as well as the size and shape of the holes in the cup holder determine the filtering speed.

[0004] Most existing coffee filter cups and cup holders are integrated designs, and can only use the same filter paper according to the cup type, which is inflexible. Due to its integrated design, the flavor of the coffee produced by the traditional coffee filter cup is basically fixed and the taste is monotonous. In addition, hand-brewed coffee is a slow lifestyle, and the monotonous and fixed coffee filter cups lack the fun of using. Utility Model Content

[0087] The application content is further explained below through the description of embodiments in conjunction with the accompanying drawings.

[0088] A first aspect of the present embodiment provides a modular coffee filter cup kit, such as Figure 1 Schematic diagram of the structure of the coffee filter cup kit, which includes:

[0089] A coffee filter cup 1 has a container space opening upward, the coffee filter cup 1 has a plurality of flow guiding structures inside the cup body, and a through hole at the bottom, wherein the flow guiding structures are used to increase the water flow speed.

[0090] The guide structure includes: convex ribs and concave ribs; one of the convex ribs is composed of two convex lines, and the convex ribs can increase the space between the filter paper 2 and the coffee filter cup 1, increase the exhaust effect, and thus increase the water flow rate to a certain extent.

[0091] 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.

[0092] Among them, bypass water refers to water that does not pass through or does not completely pass through coffee powder during coffee brewing. The depth of the concave ribs can control the contact time between water and coffee powder, and by increasing the bypass water, the water flow rate can be adjusted. Specifically, when the concave ribs are shallower, the coffee filter cup 1 and the filter paper 2 fit more tightly, the concave ribs guide and store water, that is, the bypass water is poor, the water flow is slower, the extraction is more complete, but it is also easy to over-extract; the deeper the concave ribs, the lower the fit between the coffee filter cup 1 and the filter paper 2, the concave ribs guide and store water, that is, the ability of bypass water is strong, therefore, the water flow rate is faster, but it is also easy to cause insufficient extraction of the powder bed in the lower part.

[0093] Specifically, the concave ribs can enhance the exhaust effect. Since the concave ribs can form an air circulation channel between the filter paper 2 and the coffee filter cup 1, the air and water are prevented from mutually repelling each other and affecting the extraction efficiency. Especially in the steaming stage at the beginning of brewing, a large amount of air in the coffee will be released. If it cannot be discharged well, the air will break through the coffee powder bed from the lower filter port and upwards. Breaking through the coffee powder bed upwards will allow cold air to enter and reduce the extraction efficiency. Therefore, the shallower the depth of the concave ribs, the worse the exhaust effect; conversely, the stronger the exhaust effect.

[0094] 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.

[0095] A cup holder 3 has a through hole, and the coffee filter cup 1 is arranged on the cup holder 3. The filter paper 2 is placed in the volume space of the coffee filter cup 1, and can be used with different models of coffee filter cups 1 and cup holders 3 to produce coffee with different flavors.

[0096] Specifically, the coffee filter cup 1 preferably uses ceramic material, which has stable properties and strong corrosion resistance, and can avoid affecting the quality of coffee. Different coffee filter cups 1 can be used with fan-shaped, cone-shaped or corrugated filter paper 2. When in use, put the filter paper 2 into a suitable coffee filter cup 1, and wet the filter paper 2 with hot water in advance so that the filter paper 2 can fit in the filter cup body, while also achieving the effect of warming the cup and cleaning the filter paper. In addition, the design in this application does not change the strength of the filter paper.

[0097] The ribs of different shapes and numbers on the inner wall of the coffee filter cup 1 are matched with the cup holder 3 with through holes of different areas and shapes. When the cup holder 3 with a small through hole area is selected, the water flows down at a slower speed, and the water soaks the coffee powder for a longer time. When the cup holder with a large through hole area is selected, the water flows down at a faster speed, and the water soaks the coffee powder for a shorter time. Therefore, the user can change the infiltration time of the water on the coffee powder and the water flow speed during the filtering process by changing the combination of the coffee filter cup 1 and the cup holder 3, so as to obtain coffee with different flavors and tastes.

[0098] Specifically, the cup holder 3 may have a cup groove for limiting the position of the coffee filter cup 1. At this time, the connection between the coffee filter cup 1 and the cup holder 3 forms a tight assembly structure through the design of the cup groove with a small tolerance and the size fit between the coffee filter cup 1 and the cup holder 3, ensuring that during the process of making hand-brewed coffee, the coffee liquid will not overflow from the connection between the coffee filter cup 1 and the cup holder 3, causing waste and dirt. The cup holder 3 may also not have a cup groove, and the coffee filter cup 1 is stacked on the cup holder 3 and can spin around the longitudinal axis. On the other hand, the stacking assembly method of the present application is simple, intuitive, and easy to use.

[0099] In one embodiment, there is also provided a Figure 2 and Figure 3 The coffee filter cup 11 shown, 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 at the lower middle side of the interior of the coffee filter cup.

[0100] This embodiment uses twelve vertical ribs to increase the water flow diversion speed, guide the water flow vertically and evenly through the coffee powder bed, achieve uniform extraction and avoid over-extraction. The coffee filter cup 11 also has three transverse annular ribs on the lower middle side of the cup body. When the coffee filter cup 11 is used, coffee powder is poured into the coffee filter cup to form a coffee powder bed. The three transverse annular ribs are located in the lower middle part of the coffee powder bed, increasing the water flow path and avoiding insufficient contact time between coffee powder and water due to the excessively fast water flow velocity of the vertical ribs.

[0101] In addition, the vertical and horizontal staggering of the vertical ribs and the transverse annular ribs in this embodiment can cause disturbance of the water flow along the wall, thereby increasing the extraction efficiency of the lower middle part of the powder bed.

[0102] The raised design of the ribs can increase the space between the filter paper and the filter cup, thereby enhancing the exhaust effect, thereby increasing the water flow rate to a certain extent. Using the coffee filter cup 11, the brewing flow rate is fast, which can enhance the various layered flavors of coffee and obtain a relatively refreshing taste.

[0103] The coffee filter cup 11 of this embodiment can be adapted to the corrugated filter paper 21 and the conical filter paper 23, 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 the fastest filtering speed, highlight the coffee flavor layers, and maintain a refreshing taste.

[0104] 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 is the cup holder with the second largest through-hole area. The combination can achieve uniform extraction, the filter cup flow rate is faster, highlighting the balanced flavor of the coffee and maintaining a refreshing taste.

[0105] The coffee filter cup 11 of this embodiment can be matched with the third cup holder 33, which is the cup holder with the third largest through-hole area. If the conical filter paper 23 is used, the effect is equivalent to the combination with the second cup holder 32, which can achieve faster filtering, highlight the coffee flavor level, and maintain a refreshing taste. If the corrugated cup filter paper is used, the coffee powder layer is thinner, and uniform extraction can be achieved. The flow rate of the coffee filter cup 11 is lower than that of the previous combination, highlighting the balanced coffee flavor and maintaining a mellow taste.

[0106] The coffee filter cup 11 of this embodiment can be matched with the 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, uniform extraction can be achieved, the filter cup flow rate is faster, the coffee flavor is balanced, and the taste is improved.

[0107] In one embodiment, there is also provided a Figure 4 and Figure 5 The coffee filter cup 12 shown has a buffer belt on the upper inner side, twelve vertical ribs are evenly arranged below the buffer belt, and three transverse annular ribs are arranged at the lower inner part of the coffee filter cup body.

[0108] 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.

[0109] 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 one-knife flow), the dragging ability of 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.

[0110] 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. The combination can achieve faster filtering, highlight the coffee flavor layers, and maintain a refreshing taste.

[0111] 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.

[0112] The coffee filter cup 12 of this embodiment can be matched with the third cup holder 33, which is the cup holder with the third largest through-hole area. If the conical filter paper 23 is used, the effect is equivalent to the combination of the first cup holder 31, and a moderate filtering speed can be achieved, highlighting the coffee flavor level and maintaining a refreshing taste. If the corrugated filter paper 21 is used, the coffee powder layer is thinner, and uniform extraction can be achieved. The filter cup flow rate is lower than that of the conical filter paper 23, highlighting the balanced coffee flavor and maintaining a mellow taste.

[0113] The coffee filter cup 11 of this embodiment can be matched with the 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, and uniform extraction can be achieved. The flow rate of the coffee filter cup is moderate, the coffee flavor is balanced, and the taste is mellower.

[0114] In one embodiment, there is also provided a Figure 6 and Figure 7 In the coffee filter cup 13 shown, the convex ribs include: dot matrix bars and guide grooves. The dot matrix bars are convex lines formed by a plurality of convex points; the guide grooves are rounded concave guide grooves formed by two convex lines; the guide grooves are arranged between the dot matrix bars at intervals; one end of the dot matrix bar 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 grooves extend from the middle of the coffee filter cup to the bottom of the coffee filter cup.

[0115] Specifically, the one dot matrix strip constitutes one convex line, the two convex lines constitute a convex rib, and the guide groove is arranged between each convex rib, that is, the guide groove is arranged at intervals between the dot matrix strips.

[0116] In this embodiment, twelve dot matrix strips composed of convex dots are evenly arranged inside the coffee filter cup 13, and twelve guide grooves are arranged between the dot matrix strips at intervals. 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.

[0117] The twelve dot matrix strips formed by the convex points 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.

[0118] Twelve rounded concave guide grooves extending from the middle of the cup body to the bottom of the filter cup accelerate the water flow rate from the middle bottom, reduce the extraction efficiency of the middle bottom, and avoid over-extraction caused by accumulation of fine powder and excessive extraction of dot matrix ribs. The coffee filter cup 13 of this embodiment has a moderate brewing flow rate, a variety of flavors, and a high degree of cleanliness of the produced coffee.

[0119] The coffee filter cup 13 of this embodiment can be adapted to the corrugated and conical filter papers 23, 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 faster filtering, highlight the coffee flavor layers, and maintain a refreshing taste.

[0120] 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 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 is moderate, highlighting the balanced flavor of the coffee and maintaining a refreshing taste.

[0121] The coffee filter cup 13 of this embodiment can be matched with the third cup holder 33, which is the cup holder with the third largest through-hole area. If the conical filter paper 23 is used, the effect is equivalent to the combination of the second cup holder 32, and a lower filtering speed can be achieved, highlighting the coffee flavor level and maintaining a refreshing taste. If the corrugated filter paper 21 is used, the coffee powder layer is thinner, and uniform extraction can be achieved. The filter cup flow rate is slightly lower than that of the conical filter paper 23 combination, highlighting the balanced coffee flavor and maintaining a mellow taste.

[0122] The coffee filter cup 13 of this embodiment can be matched with the 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, and uniform extraction can be achieved. The flow rate of the coffee filter cup is slower, the coffee flavor is balanced, and the taste is mellower.

[0123] In one embodiment, there is also provided a Figure 8 and Fig. 9In the coffee filter cup 14 shown, the convex ribs include: a first convex rib and a second convex rib. The first convex rib and the second convex rib are both right-angle guide grooves formed by two convex lines; the right-angle guide groove has a depth of 0.2 cm.

[0124] The first rib and the second rib are inclined in opposite directions; the extension lines of the first rib and the second rib are inclined at an angle of about 45 degrees. 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 rib and the second rib.

[0125] Specifically, in this embodiment, the width of the buffer zone may be 1.1 cm. Four first convex ribs and four second convex ribs are provided respectively.

[0126] In this embodiment, the number of ribs is small, so the speed of diversion is also slow. The design of the first rib and the second rib being tilted in opposite directions forms diversion in different directions, extends the water flow path, and forms a vortex-like stirring. A 1.1 cm buffer zone is reserved between the first rib and the second rib, and the filter paper will form a gap with the cup body in this part to create an exhaust space, which alleviates the situation where the overall flow rate of the ribs is too slow. The coffee filter cup 14 in this embodiment has a slow brewing flow rate, and the coffee produced is similar to the immersion extraction, and its taste is mellow and rich. The coffee filter cup 14 in this embodiment can be adapted to 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, highlight the coffee flavor level, and maintain a refreshing taste.

[0127] 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 is the cup holder with the second largest through-hole area. The combination can achieve uniform extraction, and the filter cup flow rate is moderate, highlighting the balanced flavor of the coffee and maintaining a refreshing taste.

[0128] The coffee filter cup 14 of this embodiment can be matched with the third cup holder 33, which is the cup holder with the third largest through-hole area. If the conical filter paper 23 is used, the effect is equivalent to the combination of the first cup holder 31, and a lower filtering speed can be achieved, highlighting the coffee flavor level and maintaining a refreshing taste. If the corrugated filter paper 21 is used, the coffee powder layer is thinner, and uniform extraction can be achieved. The flow rate of the coffee filter cup 14 is slightly lower than that of the combination of the conical filter paper 23, highlighting the balanced coffee flavor and maintaining a mellow taste.

[0129] The coffee filter cup 14 of this embodiment can be matched with the 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, uniform extraction can be achieved, the flow rate of the filter cup is slower, the coffee flavor is balanced, and the taste is improved.

[0130] In one embodiment, there is also provided a Fig.10 and Fig.11 In the coffee filter cup 15 shown, the ribs include: corrugated curved ribs; the corrugated curved ribs are evenly arranged laterally inside the entire cup body, increasing the water flow path, causing disturbance of the water flow along the wall, and increasing the extraction time and efficiency.

[0131] Specifically, because of the curves and convexities of the corrugated ribs, the water flow can cause different impact states on the lower layer of coffee powder at the valley point and the peak point. The peak point disperses the water flow, and the valley point gathers the water flow. When the brewing water surface reaches the surface of the powder bed, the extraction tends to be an immersion extraction. When brewing with the coffee filter cup 15 in this embodiment, the flow rate is slow, the taste is balanced, and the mellowness is high.

[0132] The coffee filter cup 15 of this embodiment can be adapted to the corrugated and conical filter papers 23, and matched with the first cup holder 31.

[0136] In one embodiment, there is also provided a Fig.12 and Fig.13 In the coffee filter cup 16 shown, 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.

[0137] In this embodiment, fifteen spiral ribs are used. The number of ribs is large, the diversion effect is better, and the water flow rate is faster. However, through the setting of the spiral shape, the spiral direction extends the diversion path, thereby achieving a moderate flow rate. In this embodiment, the ribs are arranged with a large transverse surface area, and the filter paper fits the surface area of ​​the ribs, which appropriately reduces the dragging ability of the water flow, increases the contact time between the water and the coffee powder bed, and improves the extraction efficiency.

[0138] Specifically, when brewing, when the water level is low or drops, the water flow will be concentrated toward the center along the spiral ribs, which will form a squeezing effect on the coffee powder to a certain extent, promote the contact between water and coffee powder, and improve the extraction efficiency. The coffee brewed using the coffee filter cup of this embodiment has a moderate brewing flow rate, rich flavor layers, and a mellow taste.

[0139] The coffee filter cup 16 of this embodiment can be adapted to the corrugated and conical filter papers 23, and can be matched with the first cup holder 31.

[0141] The coffee filter cup 16 of this embodiment can be matched with the third cup holder 33, which is the cup holder with the third largest through-hole area. If the conical filter paper 23 is used, the effect is equivalent to the combination of the first cup holder 31, which can achieve faster filtering, highlight the coffee flavor level, and maintain a refreshing taste. If the corrugated filter paper is used, the coffee powder layer is thinner, and uniform extraction can be achieved. The flow rate of the coffee filter cup is slightly lower than that of the combination of the conical filter paper 23, which highlights the balanced coffee flavor and maintains a mellow taste.

[0142] The coffee filter cup 16 of this embodiment can be matched with the fourth cup holder 34, which is the cup holder with the smallest through-hole area. When matched with the corrugated filter paper 21, the coffee powder layer is thinner, and uniform extraction can be achieved. The coffee filter cup 16 has a faster flow rate, a balanced coffee flavor, and a mellower taste.

[0143] In one embodiment, there is also provided a Fig.14 and Fig.15 The coffee filter cup 17 shown, the ribs include: water drop-shaped ribs; the water drop-shaped ribs are wide at the top and narrow at the bottom. Buffer zones are provided between the water drop-shaped ribs and the bottom and upper edge of the coffee filter cup, which increases the exhaust effect of the coffee filter cup 17. When brewing coffee, when coffee powder and water come into contact, a good exhaust effect is achieved, thereby increasing the extraction efficiency.

[0144] The cup body of the coffee filter cup 17 is a fan-shaped filter cup 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 an "I"-shaped line. The cup body is a fan-shaped filter cup that is wide at the top and narrow at the bottom, and the bottom is an "I"-shaped line, which is conducive to evenly distributing the coffee powder and reducing the stacking of coffee powder. In addition, the narrow I-shaped through-hole structure at the bottom is also conducive to concentrating the brewing water. The bottom filtration area is smaller, which slows down the water flow rate. The cup shape of the coffee filter cup 17 has a smaller angle, a longer side wall, and a shorter distance between the center and the filter cup wall, which can effectively increase the contact time between the powder and water and improve the extraction efficiency.

[0145] The coffee filter cup 17 of this embodiment can be adapted to the fan-shaped filter paper 22 and matched with the first cup holder 31, which is the cup holder with the largest through hole area. When used together, the coffee filter cup 17 has a slow flow rate and a mellow coffee taste.

[0146] 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 thick.

[0147] In one embodiment, there is also provided a Fig.16 and Fig.17 The coffee filter cup 18 shown, the ribs of the coffee filter cup 18 include: full-length water drop-shaped ribs and half-length water drop-shaped ribs, and the water drop-shaped ribs are of a structure that is wide at the top and narrow at the bottom. Half of the water drop-shaped ribs are 1 / 2 of the full-length water drop-shaped ribs, and the half-length water drop-shaped ribs are spaced apart from the full-length water drop-shaped ribs. Buffer zones are provided between each water drop-shaped rib and the bottom and upper edge of the coffee filter cup. The exhaust effect of the coffee filter cup is increased, and the purpose is to achieve a good exhaust effect and increase the extraction efficiency when the powder and water come into contact during brewing coffee. There are buffer zones on the top and bottom, so the top of the coffee filter cup is a smooth cup wall, which has a higher fit with the filter paper under the infiltration of water flow, and the dragging ability of the water flow is weakened, and the exhaust ability is weakened, which reduces the phenomenon of excessive water flow velocity caused by high water level pressure, thereby achieving a better soaking effect.

[0148] In addition, the half-length convex ribs reduce the height, appropriately reducing the diversion effect at high water levels and slowing down the water flow rate.

[0149] The coffee filter cup 18 of the present embodiment can be adapted to the fan-shaped filter paper 22 and matched with the first cup holder 31.
