Description

Technical Field

[0001] This utility model relates to the field of coffee making equipment, specifically a multifunctional coffee brewing cup. Background Technology

[0002] As a globally popular beverage, coffee's brewing quality and ease of preparation have always been core consumer concerns, especially in non-fixed scenarios such as outdoor camping and business travel, where the demand for portable and efficient coffee brewing solutions is increasingly urgent. However, current traditional coffee brewing methods and existing equipment still have many technical shortcomings, making it difficult to meet users' comprehensive needs for convenience, brewing accuracy, and drinking experience. Specific problems are as follows: 1. The functions of the device are separate, resulting in poor portability. Traditional coffee brewing relies on the coordinated use of multiple independent tools. Typically, a grinder (for grinding coffee beans into brewable powder), a pour-over kettle (for storing and pouring hot water), a filter cup (for holding filter paper and coffee grounds for extraction), and a drip tray (for collecting the brewed coffee) must be carried separately. These tools function independently, lacking an integrated design. They are not only bulky and heavy, but also require separate storage and transport. This makes them prone to being forgotten or inconvenient to carry in outdoor or mobile settings, severely limiting the adaptability of coffee brewing in various environments.

[0003] 2. Difficulty in precisely controlling the brewing water temperature affects coffee quality. Coffee brewing requires strict control over water temperature. Different types of coffee beans (such as Arabica and Robusta) and grind sizes need to be matched with specific water temperatures (usually between 88℃ and 96℃). Water that is too hot can cause the coffee to taste burnt and bitter, while water that is too cold will result in insufficient extraction of flavor and a weak taste. However, in outdoor settings, without power, or in temporary locations, users often struggle to obtain a stable heat source to prepare the required brewing water. Furthermore, existing portable brewing devices lack effective temperature control mechanisms, causing the water temperature to fluctuate rapidly with changes in ambient temperature. This makes it impossible to maintain a constant water temperature during brewing, directly leading to inconsistent coffee quality and difficulty in achieving the desired taste.

[0004] Third, the brewing process is cumbersome, inefficient, and prone to spillage. Traditional brewing processes require multiple transfers of materials between several independent appliances: first, coffee beans must be ground in a grinder, then the ground coffee powder must be transferred to a filter cup; simultaneously, cold water must be heated and poured into a pour-over kettle, then water must be poured from the kettle into the coffee powder in the filter cup; finally, the brewed coffee liquid must flow through the filter cup into a receiving cup. These multiple transfers not only prolong brewing time and reduce efficiency, but also increase the risk of spillage due to improper coordination between appliances or limited operating space, leading to material waste and increased cleaning difficulty, further impacting the user experience.

[0005] 4. Insufficient heat retention of coffee liquid easily leads to a decline in flavor. After brewing, coffee needs to be consumed at a suitable temperature (usually 60℃-75℃) to ensure optimal flavor. If the temperature drops too quickly, the coffee will taste bitter and lose its aroma. Most existing brewing equipment (such as filter cups and ordinary serving cups) are single-layered structures made of highly thermally conductive materials, lacking dedicated heat insulation design. The brewed coffee easily exchanges heat rapidly with the external environment, causing a significant temperature drop in a short time. This heat preservation problem is particularly prominent in low-temperature outdoor environments, severely impacting the user's drinking experience. Utility Model Content

[0018] The multi-functional coffee brewing cup provided in this solution addresses the technical shortcomings of traditional coffee brewing methods in terms of portability, operational efficiency, and heat preservation performance through the integrated and optimized design of the cup structure and functional modules. Its main advantages include the following: I. Achieve ultimate portability and significantly reduce scenario limitations Addressing the issues of traditional brewing solutions requiring multiple separate appliances such as grinders, kettles, filter cups, and serving cups, resulting in bulkiness, inconvenience, and easy loss, this solution integrates multiple components into a nested storage design. This highly integrates functions such as boiling water, grinding, brewing, filtering, and heat preservation into a single unit. In its stored state, the second cup is nested within the first cavity of the first cup, and the grinding unit is fitted inside the second cup. The entire product is compact and small when stored, eliminating the need to separately store multiple appliances and significantly reducing space and weight burden during transport. Users only need to carry a single product to meet their complete brewing needs in mobile scenarios such as travel, camping, and business trips, completely solving the pain points of traditional solutions' "separate appliances and cumbersome carrying," and significantly improving the adaptability of coffee brewing in various scenarios. II. Simplify the operation process and improve brewing efficiency and safety. Addressing the issues of cumbersome, time-consuming, and spill-prone operations caused by the multiple transfers of coffee beans, ground coffee, hot water, and brewed coffee in traditional brewing processes, this solution achieves a seamless integration of "grinding → boiling water → brewing → drinking" through the collaborative design of functional modules. The grinding unit grinds the coffee beans, and its powder receiving section can also be used as a filter cup, eliminating the need to transfer coffee grounds. The heating unit directly heats the water in the first cup, eliminating the need for an external heat source or a pour-over kettle. This design not only significantly reduces brewing time and improves operational efficiency but also avoids spills and waste caused by material transfers, reduces cleaning steps, and further optimizes the user experience. III. Stable brewing The cup lid assembly features a columnar water outlet design, which provides a uniform and controllable water flow, ensuring that the hot water and coffee grounds are fully and evenly in contact during the brewing process. This avoids localized over-extraction or uneven extraction, further ensuring the stability of the coffee brewing effect and effectively improving the coffee quality. IV. Long-lasting heat preservation design to maintain the best drinking experience for coffee. This application utilizes a double-walled vacuum structure for the cup body. This structure effectively prevents heat exchange between the inside of the cup and the external environment, significantly reducing the rate of heat loss. Before brewing, the double-walled vacuum structure reduces temperature fluctuations in the heated water. After brewing, it maintains the coffee liquid temperature stably within the optimal drinking range. Even in low-temperature outdoor environments, it prevents a sudden drop in coffee liquid temperature, effectively preventing a bitter taste and aroma loss, ensuring that users can experience the best flavor of coffee throughout the entire drinking process. V. Hygienic and easy-to-clean features and adaptability to various scenarios, expanding the product's practicality. This solution balances hygiene and scenario adaptability in its structural design: Firstly, the second cup can be detached independently, and the powder receiving part is also detachable for cleaning. The overall structure is simple and without complex gaps, eliminating any blind spots for hygiene. Users can easily and thoroughly clean each component, preventing residual coffee powder or stains from growing and ensuring hygienic use. Secondly, through its integrated and portable design, the product is suitable for various scenarios such as travel, camping, office, home, and business trips. Whether in outdoor environments without power (the heating unit can be used by adding a portable power supply module) or for daily indoor use, it can meet users' convenient brewing needs, greatly expanding the product's applicability and practicality. In summary, this multi-functional coffee brewing cup, through structural innovation and functional integration, comprehensively solves the technical defects of traditional coffee brewing solutions. It achieves significant improvements in portability, operational efficiency, brewing accuracy, heat preservation performance, and scenario adaptability, providing users with a coffee brewing solution that balances quality and convenience.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figures 1-10 This application provides the following technical solutions: A multifunctional coffee brewing cup includes a first cup body 1 and a second cup body 2. Both the first cup body 1 and the second cup body 2 have open upper ports and internal cavities. The second cup body 2 can be fitted into the first cavity of the first cup body 1 or used separately. As a lid for the first cup body 1 and the second cup body 2, this design includes a lid assembly 3. The lid assembly 3 can be connected to both the upper port of the first cup body 1 and the upper port of the second cup body 2. That is, when the first cup body 1 and the second cup body 2 are fitted together, the lid assembly 3 can be directly connected to the upper port of the second cup body 2, serving as the lid for the combined state of the first cup body 1 and the second cup body 2. When the first cup body 1 and the second cup body 2 are separated, the lid assembly 3 can be used as the lid for each of the two cup bodies separately.

[0023] A heating unit 4 is provided at the lower part of the first cup body 1. The heating unit 4 is an electrothermal structure used to heat the interior of the first cavity of the first cup body 1. In addition, this solution also includes a grinding unit 5, the shape of which is designed to fit inside the second cup body 2. The grinding unit 5 includes a grinding section 51 for grinding coffee beans.

[0024] Based on the structure of this scheme, see [link / reference]. Figure 1 This refers to the assembled state of the coffee brewing cup in this solution. In this state, the entire cup is integrated into a single cup-shaped structure, making it easy to store and carry. It should be noted that... Figure 3 In the cross-sectional view, the lower half of the grinding unit 5 is not cut, and it is shown as the overall state of the bean hopper 511.

[0025] When using this brewing cup, the second cup body 2 and the grinding unit 5 need to be removed separately. Water is then added to the first cup body 1, and the heating unit 4 heats the bottom of the first cup body 1 to boil the water. The removed grinding unit 5 grinds coffee beans into coffee powder. The coffee powder from the grinding unit 5 is then used with the boiled water in the first cup body 1 to brew coffee, which is then collected in the second cup body 2. This integrated coffee-making function is very convenient to use and carry.

[0026] Based on the above implementation plan, considering the heat preservation of the cup body, both the first cup body 1 and the second cup body 2 are double-layer vacuum heat preservation structures, or the first cup body 1 is made of stainless steel and the second cup body 2 is made of vacuum cup body structure.

[0027] Based on the above implementation plan, see Figure 4 In this design, the first cup body 1, the second cup body 2, and the lid assembly 3 are connected as follows: the upper end of the first cup body 1 is provided with a first connecting structure 11; the second cup body 2 is provided with a second connecting structure 21 and a third connecting structure 22; and the lid assembly 3 is provided with a fourth connecting structure 331. The fourth connecting structure 331 of the lid assembly 3 corresponds to the first connecting structure 11 of the first cup body 1 and the third connecting structure 22 of the second cup body. The second connecting structure 21 of the second cup body 2 corresponds to the first connecting structure 11 of the first cup body.

[0028] Various connection structures can take many different forms, such as plug-in, snap-fit, screw-on connection, etc. Therefore, the specific structural form of the cup lid assembly 3 also needs to be considered. The specific implementation of each connection structure will be further detailed later.

[0029] Based on the above implementation plan, see Figure 5The cup lid assembly 3 includes an outer lid 31, a flip lid 32, a cup lid body 33, and a cup lid seal 34. The cup lid body 33 has a cylindrical structure with an open lower end. A fourth connecting structure 331, which is an external threaded connection, is provided on the lower part of the outer wall of the cup lid body 33. The upper surface of the cup lid body 33 has a vent hole and a through hole, the through hole being a direct drinking spout. The outer lid 31 is fastened to the upper outer side of the cup lid body 33, and the outer lid 31 and the cup lid body 33 are snapped together. A cup lid seal 34, which is a sealing ring, is provided on the lower side of the outer lid 31, surrounding the cup lid body 33. The flip lid 32 is rotatably connected to the outer lid 31, and a sealing plug is provided on one side of the flip lid 32 corresponding to the direct drinking spout on the cup lid body 33.

[0030] The first connecting structure 11 of the first cup body 1 is an internal thread structure located inside its upper port. The cup lid assembly 3 and the first cup body 1 are connected by the first connecting structure 11 and the fourth connecting structure 331. After the two are connected, the cup lid seal 34 seals the connection between them.

[0031] The third connecting structure 22 of the second cup body 2 also adopts an internal thread structure. The fourth connecting structure 331 and the third connecting structure 22 can be threaded together, thereby realizing the connection between the cup lid assembly 3 and the upper port of the second cup body 2. The cup body of the second cup body 2 is provided with an inwardly recessed stepped structure. This stepped structure is an annular body corresponding to the second cup body 2, and the upper inner diameter of the stepped structure is larger than the lower inner diameter. A second connecting structure 21 is provided on the lower outer wall of the stepped structure. The second connecting structure 21 is an external thread structure, and the second cup body 2 can be threadedly connected to the first connecting structure 11 of the first cup body 1 through the second connecting structure 21.

[0032] A second cup body seal 23 is provided on the lower side of the stepped structure of the second cup body 2, that is, on the upper side of the second connecting structure 21. The second cup body seal 23 is also a sealing ring. When the second cup body 2 and the first cup body 1 are connected, the second cup body seal 23 provides a sealing effect at the connection between the two.

[0033] Based on the above implementation plan, see Figure 4 The heating unit 4 includes a base 41 and a heating element 42. The base 41 is located at the bottom of the first cup body 1, and its upper end is connected to the first cup body 1. The connection method is not limited, as long as it ensures that the connection between the two is stable, firm, and leak-proof. The heating element 42 is located on the upper side of the base 41 and on the lower side of the first cup body 1. The heating element 42 is an electric heating element that can heat the bottom of the first cup body 1. The heating element 42 is used to heat the water inside the first cup body 1.

[0034] Based on the above implementation scheme, as an optimization, the heating unit 4 adopts an external power supply, with a power socket reserved on the base 41. A thermostat is electrically connected to the heating element 42, and a control panel is reserved on the outside of the base 41. A temperature sensor is installed on the base 41, with the sensing end of the temperature sensor extending into the interior of the first cup body 1. The control panel, temperature sensor, and thermostat are used to control the water temperature inside the first cup body 1 to better meet the brewing requirements of different types of coffee. Specific details regarding electric water heating and temperature control can be achieved using existing technology and will not be elaborated here.

[0035] Based on the above implementation plan, see Figures 6 to 9 The grinding unit 5 includes a grinding section 51 and a coffee powder receiving section 52. Considering the convenience of coffee brewing, this design uses the grinding section 51 to grind coffee beans, and the ground coffee powder is collected by the receiving section 52. The receiving section 52 then serves as a brewing filter for coffee. Water boiled in the first cup 1 is poured into the receiving section 52, and the coffee filtered out by the second cup 2 is collected. This achieves the entire coffee-making process from boiling water to brewing, without the need to transfer coffee powder, making it very convenient to use. There is no technical barrier to entry for ordinary coffee enthusiasts.

[0036] Based on the above implementation scheme, the grinding unit 51 includes a bean hopper 511 inside which coffee beans to be ground can be placed. The bean hopper 511 is a cylindrical body with a coffee bean inlet at the top and a grinding port on the bottom, from which ground coffee powder falls out. The grinding assembly 512 includes a grinding structure disposed at the grinding port of the bean hopper 511 and a drive structure serving as the power source for the grinding assembly 512.

[0037] The drive structure includes a drive housing 5121, the outer diameter of which is smaller than the inner diameter of the second cup body 2. A switch is provided on the top of the drive housing 5121, and the interior is a cavity. A motor and a rechargeable battery are fixedly installed inside the cavity of the drive housing 5121, and a charging port is reserved on the shell wall of the drive housing 5121.

[0038] A linkage rod 5125 is coaxially mounted with the motor shaft of the motor. A support structure is installed inside the bean hopper 511, and the linkage rod 5125 is located inside the bean hopper 511, rotatably connected to the bean hopper 511 coaxially via the support structure and bearings. The upper end of the linkage rod 5125 is inserted into the motor shaft of the motor via a sleeve structure. The specific connection method between the linkage rod 5125 and the motor shaft can be various, as long as it satisfies the requirement that the motor shaft can drive the linkage rod 5125 to rotate and provide grinding force.

[0039] The grinding structure includes a first grinding element 5122 and a second grinding element 5123. The first grinding element 5122 is inserted into the lower end of the motor shaft of the motor, and the two can move synchronously. The second grinding element 5123 is located below the first grinding element 5122 and is fixedly connected to the bean hopper 511. The first grinding element 5122 is a conical block, with its smaller end being the upper end. The second grinding element 5123 is an annular cylinder, with its bottom end fixedly connected to the lower part of the bean hopper 511 via a connecting bracket. The inner wall of the second grinding element 5123 has a structure corresponding to that of the first grinding element 5122, and several grinding grooves are distributed on the inner wall of the second grinding element 5123.

[0040] Based on the above implementation scheme, the inner wall of the second grinding component 5123 is divided into upper and lower parts, both of which are conical structures. The conical structure of the lower part of the inner wall is oriented with a smaller upper end and a larger lower end, while the conical structure of the upper part is the opposite, with the larger end being the upper end. The lower part of the inner wall corresponds in shape to the first grinding component 5122, and grinding grooves are distributed on the lower part of the inner wall. The grinding grooves are arc-shaped inclined grooves. The upper part of the inner wall is distributed with feeding grooves, which are also inclined grooves.

[0041] With this structure, coffee beans are squeezed into the grinding chamber after passing through the feeding trough. As the first grinding element 5122 and the second grinding element 5123 move relative to each other, they are ground into powder and then fall.

[0042] Based on the above implementation scheme, the grinding structure also includes an adjusting member 5124. The adjusting member 5124 is linked with either the first grinding member 5122 or the second grinding member 5123 to adjust the grind size of the coffee beans. The adjusting member 5124 adjusts the grind size by adjusting the relative position of the first grinding member 5122 and the second grinding member 5123 in the vertical direction, thereby changing the distance between the lower inner walls of the first grinding member 5122 and the second grinding member 5123. The specific linkage between the adjusting member 5124 and the first grinding member 5122 can be achieved using existing linkage structures, and will not be elaborated here.

[0043] Based on the above implementation scheme, in order to achieve the integration of coffee grinding and brewing, this scheme provides a powder receiving section 52 at the lower part of the grinding section 51 to receive the coffee powder ground by the grinding section 51. The powder receiving section 52 is located below the bean hopper 511. The powder receiving section 52 includes a filter screen 521 and a connecting frame 522. The filter screen 521 is detachably connected to the bottom of the bean hopper 511. The filter screen 521 has a spherical mesh structure, with its concave side facing the bean hopper 511. The filter screen 521 is used to receive the ground coffee powder, and its mesh size is sufficient to prevent coffee powder from leaking out while allowing coffee liquid to flow out during brewing. The connecting frame 522 is used to mount the grinding unit 5 on the second cup body 2 for use as a filter cup. The connecting frame 522 can be implemented in various different ways; this scheme provides one of the following.

[0044] The connecting frame 522 of this solution includes three connectors, each a "L"-shaped plate, evenly distributed around the periphery of the filter screen 521. One end of each connector is rotatably connected to the side of the filter screen 521. The connectors have two states: a stored state and a state used as a filter cup stand. Figures 6 to 8 The images show the coffee in its stored state, where the connecting bracket 522 hangs down with its bent plate facing the center of the filter 521. In this state, it can be stored inside the second cup body 2. In the erected state, the connecting piece is rotated outwards to open, at which point the upper part of the connecting piece is horizontal, limited by the filter 521 and its connecting structure, with the bent plate facing downwards. In this state, the connecting bracket 522 can be placed directly on top of the second cup body 2. Water boiled inside the first cup body 1 is poured in through the bean hopper 511. The water passes through the bean hopper 511 into the filter 521, comes into contact with the coffee powder, and then flows through the filter 521 into the second cup body 2, becoming coffee liquid.
