Description

Technical Field

[0001] This utility model relates to the field of coffee equipment technology, and in particular to a capsule coffee brewing cup. Background Technology

[0002] As living standards improve, coffee capsules are becoming increasingly popular in the coffee market due to their convenience. Capsule coffee brewing cups, used in conjunction with coffee capsules, allow for the quick brewing of a cup of coffee, meeting the immediate demand for high-quality coffee in today's fast-paced lifestyle.

[0003] Traditional capsule coffee brewing cups mostly work by using spikes or other structures to puncture the coffee capsule, allowing hot water to flow into the capsule and fully contact the coffee grounds to extract the coffee liquid. However, this puncture method has an inherent flaw: at the moment the spike punctures the coffee capsule, due to factors such as internal pressure and the impact of the water flow, some coffee grounds inevitably escape. These escaped coffee grounds mix into the coffee liquid during the extraction process, ultimately affecting the overall taste of the coffee. This often results in brewed coffee with fine grounds, lacking smoothness and failing to achieve the pure and smooth taste standard of high-quality coffee.

[0004] To address this issue, the industry has gradually introduced the design concept of incorporating a filter structure within the brewing cup, such as a mesh filter. This type of filter can, to some extent, intercept any escaping coffee grounds, preventing most of the coffee grounds from entering the final beverage, thus improving the coffee's flavor. However, after multiple brewing cycles, the coffee grounds (grounds) trapped by the filter structure gradually accumulate on the filter and other filter components. This accumulated residue clogs the mesh, reducing filtration efficiency and causing uneven flow of coffee liquid during subsequent brewing, affecting extraction. Furthermore, the residual coffee grounds, adhering to the filter structure for extended periods, are highly susceptible to bacterial growth, mold, and spoilage. When reused, these impurities will mix into the freshly brewed coffee, seriously threatening its hygiene and quality, and imparting an off-flavor, significantly diminishing the drinking experience.

[0005] Therefore, there is an urgent need to develop a capsule coffee brewing cup structure design that allows for easy and quick disassembly of the capsule coffee brewing cup to facilitate cleaning of the filter structure. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a capsule coffee brewing cup structure that allows the capsule coffee brewing cup to be easily and quickly disassembled so as to clean the filter structure in a timely and thorough manner, maintain the good working condition of the brewing cup and the high quality of coffee brewing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A capsule coffee brewing cup includes an upper cup body and a lower cup base. The upper cup body has a built-in primary extraction guide, and a capsule receiving cavity and a filter cavity are formed above the primary extraction guide inside the upper cup body. The top of the primary extraction guide is provided with a spiked support plate for piercing coffee capsules. The lower cup base has an upper opening and a coffee outlet at the bottom. A secondary extraction guide is provided inside the lower cup base, and a filter sheet is provided at the top of the secondary extraction guide. The lower half of the upper cup body is fitted onto the secondary extraction guide and the two are detachably connected, so that the secondary extraction guide and the filter sheet are embedded in the filter cavity, and the filter sheet is located between the primary extraction guide and the secondary extraction guide.

[0009] As a further improvement to the above technical solution, multiple locking blocks are provided on the outer wall of the secondary extraction guide, and corresponding screw-in slots are provided on the upper cup body, and the locking blocks can be rotated into the screw-in slots.

[0010] As a further improvement to the above technical solution, one of the card blocks is provided with a positioning protrusion, and the upper cup body has a resistance protrusion that cooperates with the positioning protrusion in the screw-on slot. The resistance protrusion provides resistance to the positioning protrusion in the unlocking direction.

[0011] As a further improvement to the above technical solution, the primary extraction guide includes a sinking plate integrally formed with the upper cup body, multiple diversion protrusions set on the sinking plate, multiple drip holes arranged in a circumferential array on the sinking plate, and multiple overflow ports set on the outer periphery of the drip holes. The multiple diversion protrusions form a first coffee flow channel, so that the coffee in the first coffee flow channel can flow evenly to each drip hole or overflow port.

[0012] As a further improvement to the above technical solution, the spiked support plate includes a plate body and a plurality of conical spikes arranged at intervals on the plate body. The bottom surface of the plate body has seepage ports that are the same number as the number of spikes and correspond one-to-one. The conical surfaces of the conical spikes have a plurality of seepage grooves that communicate with the seepage ports.

[0013] As a further improvement to the above technical solution, a first sealing ring is provided on the outer wall of the upper cup body, so that the outer wall of the upper cup body and the inner side of the lower cup seat form a seal; a second sealing ring is provided on the outer wall of the secondary extraction guide, so that the outer wall of the secondary extraction guide and the inner side of the upper cup body form a seal.

[0014] As a further improvement to the above technical solution, the secondary extraction guide has a built-in labyrinthine second coffee flow channel and an eccentrically positioned extraction outlet, which is connected to the coffee outlet.

[0015] As a further improvement to the above technical solution, the filter sheet covers the second coffee flow channel and a third sealing ring is provided between the filter sheet and the secondary extraction guide.

[0016] As a further improvement to the above technical solution, the outer side wall of the upper cup body is provided with a buckle protrusion that can be rotatably engaged with the water inlet base.

[0017] As a further improvement to the above technical solution, the top surface of the upper cup body is provided with multiple rotating grooves.

[0018] The beneficial effects of this utility model: The capsule coffee brewing cup provided by this utility model adopts a split design where the upper cup body and the secondary extraction guide component on the lower cup base are connected by a snap-fit ​​structure, solving the problem of difficult cleaning of previous filter structures. After multiple brewing operations, even if residual coffee grounds accumulate on the filter sheet, users can easily and quickly disassemble the capsule coffee brewing cup to thoroughly clean the filter components. This prevents reduced filtration efficiency, uneven coffee flow rate, and hygiene hazards caused by bacteria growth and mold due to residue buildup clogging the mesh. It also prevents impurities and odors from mixing into newly brewed coffee, ensuring the hygienic quality and good drinking experience of the coffee at all times. This easy-to-disassemble and clean feature effectively extends the service life of the brewing cup, reduces the cost of frequent replacement of the brewing cup due to hygiene issues, and meets the needs of modern consumers for convenient cleaning of utensils.

Detailed Implementation

[0027] This utility model provides a capsule coffee brewing cup. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0028] Please see Figures 1 to 6 As shown, this utility model provides a capsule coffee brewing cup, including an upper cup body 1 and a lower cup base 2. The upper cup body 1 has a built-in primary extraction guide 3. A capsule receiving cavity 11 is formed above the primary extraction guide 3 and a filter cavity 12 is formed above the primary extraction guide 3 inside the upper cup body 1. The top of the primary extraction guide 3 is provided with a spiked support plate 4 for piercing coffee capsules. The lower cup base 2 has an upper opening and a coffee outlet 21 at the bottom. A secondary extraction guide 5 is provided inside the lower cup base 2. A filter sheet 6 is provided on the top of the secondary extraction guide 5. The lower half of the upper cup body 1 is fitted onto the secondary extraction guide 5 and the two are detachably connected, so that the secondary extraction guide 5 and the filter sheet 6 are embedded in the filter cavity 12. The filter sheet 6 is located between the primary extraction guide 3 and the secondary extraction guide 5.

[0029] Detachable connection methods can specifically include rotary snap-fit ​​connection, magnetic connection, and snap-fit ​​connection. The following explanation uses the rotary snap-fit ​​connection method as an example.

[0030] When using this capsule coffee brewing cup, after the coffee capsule is placed into the capsule receiving cavity 11 of the upper cup body 1, the entire brewing cup is placed on the water inlet base. The water inlet base activates, piercing the top of the coffee capsule and then injecting hot water into the capsule. At the same time, the spiked support plate 4 on the top of the primary extraction guide 3 built into the upper cup body 1 also pierces the bottom of the coffee capsule.

[0031] After hot water is injected into the capsule, it comes into full contact with the coffee grounds. Under pressure, the initial extraction begins. The coffee liquid, carrying some fine coffee grounds and other substances, flows down through the perforations of the spiked tray 4 into the primary extraction guide 3, and then drips into the filter chamber 12 below. At this time, the filter plate 6 at the top of the secondary extraction guide 5 plays a filtering role, intercepting larger coffee grounds and other impurities, so that the coffee liquid continues to flow downward after being relatively purified. After further guidance by the secondary extraction guide 5, it finally flows out smoothly through the coffee outlet 21 at the bottom of the lower cup holder 2, completing the entire coffee brewing and extraction process.

[0032] When the filter structure needs to be cleaned, by rotating the upper cup body 1 and utilizing the snap-fit ​​structure between the upper cup body 1 and the secondary extraction guide 5, the upper cup body 1 and the lower cup seat 2 can be easily separated, so that key components such as the primary extraction guide 3, the filter sheet 6 and the secondary extraction guide 5 can be cleaned efficiently.

[0033] The capsule coffee brewing cup provided by this utility model punctures the coffee capsule by setting a spiked tray 4 on the top of the primary extraction guide 3, and forming a double protection with a filter sheet 6 located between the primary and secondary extraction guides 5. The coffee powder that escapes the moment the coffee capsule is punctured, as well as the coffee powder carried out during the subsequent extraction process, can be effectively intercepted on the filter sheet 6, preventing it from mixing into the final coffee liquid. This greatly improves the smoothness of the coffee taste, making the brewed coffee closer to the pure and smooth taste standard of high-quality coffee, which is a significant improvement compared to the traditional simple puncture capsule coffee brewing cup.

[0034] Furthermore, the separate design, where the upper cup body 1 and the secondary extraction guide 5 on the lower cup base 2 are connected by a snap-fit ​​structure, solves the problem of difficult cleaning of previous filter structures. After multiple brewing operations, even if residual coffee grounds accumulate on the filter sheet 6, users can easily and quickly disassemble the capsule coffee brewing cup to thoroughly clean the filter components. This prevents reduced filtration efficiency, uneven coffee flow, and hygiene hazards caused by bacteria growth and mold due to residue buildup clogging the mesh. It also prevents impurities and off-flavors from mixing into newly brewed coffee, ensuring the hygienic quality and a good drinking experience of the coffee. This easy-to-disassemble and clean feature effectively extends the service life of the brewing cup, reduces the cost of frequent cup replacements due to hygiene issues, and meets the modern consumer demand for convenient cleaning of equipment.

[0035] For details, see Figure 3 and Figure 4As shown, multiple locking blocks 51 are located on the outer wall of the secondary extraction guide 5, and corresponding screw-in grooves 13 are provided on the upper cup body 1. When assembling the capsule coffee brewing cup, the lower half of the upper cup body 1 is aligned with the secondary extraction guide 5 inside the lower cup base 2, allowing the secondary extraction guide 5 to gradually enter the corresponding position on the upper cup body 1. At this time, the multiple locking blocks 51 on the outer wall of the secondary extraction guide 5 begin to contact the screw-in grooves 13 on the upper cup body 1. As the upper cup body 1 rotates relative to the lower cup base 2, the locking blocks 51 slide along a specific trajectory of the screw-in grooves 13 until they slide to the locking position of the screw-in grooves 13, completing the assembly of the brewing cup. Figure 5 As shown, this ensures that the secondary extraction guide 5 and the filter sheet 6 are accurately embedded in the filter chamber 12, thus ensuring the stability of the entire brewing device and enabling normal coffee extraction.

[0036] When the capsule coffee brewing cup needs to be disassembled for filter cleaning, the upper cup body 1 is rotated in the opposite direction. The locking block 51 then returns along the unlocking path of the screw-on locking slot 13. Driven by the rotational force, it slides smoothly in the opposite direction until it is completely disengaged from the screw-on locking slot 13. The upper cup body 1 can then be easily separated from the lower cup base 2. The user can then perform a deep cleaning operation on key and easily deposited components such as the internal filter sheet 6, the primary extraction guide 3, and the secondary extraction guide 5 without any obstacles.

[0037] This snap-fit ​​structure utilizes the rotational engagement of the snap-fit ​​block 51 and the screw-fit slot 13 to achieve a quick and stable connection between the upper cup body 1 and the lower cup base 2. Compared to some complex connection devices, it requires no additional tools; users can complete the assembly simply by rotating the device, greatly improving the assembly efficiency of the capsule coffee brewing cup. Whether it's the assembly process on the production line or the self-installation by consumers for first-time use, it is extremely convenient, reducing labor costs and the barrier to entry.

[0038] When the capsule coffee brewing cup is in normal use and the coffee extraction process is underway, the equipment is subjected to various external forces such as water flow impact, pressure changes, and a certain degree of vibration. This could potentially cause connection failure between the upper cup body 1 and the lower cup base 2. Therefore, in this embodiment, a positioning protrusion 52 is provided on one of the locking blocks 51. A resistance protrusion 14, which cooperates with the positioning protrusion 52, is provided in the screw-on groove 13 of the upper cup body 1. The resistance protrusion 14 provides resistance to the positioning protrusion 52 as it rotates in the unlocking direction. This resistance effectively prevents the locking block 51 from accidentally loosening or rotating in the opposite direction due to external forces, eliminating problems such as component misalignment and gaps caused by unstable connections. The cooperative design of the positioning protrusion 52 and the resistance protrusion 14 greatly enhances the stability of the upper cup body 1 and the lower cup base 2 after they are locked together.

[0039] For details, see Figure 6As shown, the spiked support plate 4 includes a plate body 41 and a plurality of conical spikes 42 spaced apart on the plate body 41. The bottom surface of the plate body 41 has seepage ports that correspond one-to-one with the number of spikes. The conical surfaces of the spikes 42 have a plurality of seepage grooves 43 communicating with the seepage ports. The design of the conical spikes 42 allows for more effortless and precise piercing of the bottom of the coffee capsule. The multiple spaced conical spikes 42 ensure that the force is evenly distributed when piercing the capsule, avoiding uneven capsule damage caused by excessive piercing in certain areas. This ensures that the coffee powder and hot water can fully and evenly contact inside the capsule, making the extraction process more efficient and stable, allowing the flavor compounds in the coffee powder to be released more comprehensively, and improving the overall quality of the coffee.

[0040] Understandably, under the influence of internal pressure and gravity, the coffee liquid can not only quickly seep downwards through the infiltration channel 43, but the infiltration port also further increases the flow path of the liquid, greatly reducing the resistance when the coffee liquid seeps out. This prevents the coffee liquid from flowing out poorly due to local blockage, ensuring that the coffee liquid can continuously, stably and quickly flow into the filter chamber 12 below throughout the entire extraction process. This avoids the problem of over-extraction or uneven extraction of coffee due to liquid accumulation, and ensures the consistency of coffee taste.

[0041] For details, see Figure 4 and Figure 6 As shown, the primary extraction guide 3 includes a sinking plate 31 integrally formed with the upper cup body 1, and multiple diversion protrusions 32 disposed on the sinking plate 31. The sinking plate 31 has multiple drip holes 33 arranged in a circumferential array and multiple overflow ports 34 disposed on the outer periphery of the drip holes 33. The multiple diversion protrusions 32 form a first coffee flow channel 35, so that the coffee in the first coffee flow channel 35 can flow evenly to each drip hole 33 or overflow port 34.

[0042] The cleverly designed first coffee channel 35, formed by multiple diversion bumps 32, precisely guides and distributes the coffee liquid flowing in after the initial extraction. This ensures the coffee liquid flows orderly within the channel and is evenly distributed to the drip holes 33 arranged in a circumferential array and the overflow outlets 34 on the outer periphery. In this way, regardless of differences in the extraction level of coffee powder at different locations within the coffee capsule, it ensures that the coffee liquid flowing from the capsule enters the next filtration process evenly, avoiding excessive concentration or insufficient flow in certain areas. This guarantees a consistent flavor and strength in every cup of coffee, improving the overall brewing quality.

[0043] Understandably, the drip hole 33 is suitable for the smooth flow of coffee liquid under normal extraction conditions. However, when there is a sudden increase in flow rate, high viscosity of coffee liquid, or abnormal internal pressure during the extraction process, the excess coffee liquid can be discharged in time through the overflow port 34 on the outer periphery, so as to avoid the accumulation of coffee liquid on the primary extraction guide 3 and prevent the coffee powder from being over-soaked due to the accumulation of liquid, which would affect the taste of coffee.

[0044] The sealing structure is crucial for maintaining the pressure environment inside the brewing cup, therefore see Figure 6 As shown, a first sealing ring 71 is provided on the outer wall of the upper cup body 1, forming a seal between the outer wall of the upper cup body 1 and the inner side of the lower cup base 2; a second sealing ring 72 is provided on the outer wall of the secondary extraction guide 5, forming a seal between the outer wall of the secondary extraction guide 5 and the inner side of the upper cup body 1. The double sealing of the first sealing ring 71 and the second sealing ring 72 effectively prevents pressure leakage, ensuring stable pressure acting on the coffee powder and extraction process. This allows the essential components of the coffee powder, such as oils and aromas, to be fully released into the coffee liquid under ideal pressure, enhancing the aroma intensity and flavor richness of the coffee, and maximizing the restoration of the flavor characteristics that high-quality coffee should possess.

[0045] See Figure 6 As shown, the secondary extraction guide 5 has a built-in labyrinthine second coffee channel 53 and an eccentrically positioned extraction outlet 54, which is connected to the coffee outlet 21. The labyrinthine second coffee channel 53 effectively prolongs the residence time and flow distance of the coffee liquid within the secondary extraction guide 5. The coffee liquid moves slowly through the tortuous and complex channel, fully contacting the inner wall of the secondary extraction guide 5, promoting the further extraction of residual subtle flavor substances in the coffee liquid, while ensuring a more uniform flow rate in all parts of the coffee liquid, avoiding some components from flowing out before extraction due to excessively fast local flow rates, achieving a deeper and more balanced secondary extraction, thereby comprehensively improving the flavor profile and richness of the coffee, making the coffee taste more mellow and full-bodied.

[0046] The off-center extraction outlet 54 breaks the localized pressure concentration that can occur with a symmetrical structure. If the extraction outlet 54 were located in the center, the coffee liquid would easily form a high-pressure zone at the center as it converges from various parts of the labyrinthine flow channel, causing the coffee liquid in the surrounding areas to flow too slowly and affecting the overall extraction uniformity. The off-center design makes the pressure distribution of the coffee liquid more even as it flows towards the outlet, allowing each part of the coffee liquid to flow out sequentially at a relatively stable flow rate. This avoids problems such as coffee liquid rushing or stagnation caused by uneven pressure, ensuring that the entire secondary extraction process takes place under a stable pressure environment. This, in turn, consistently improves the quality of coffee extraction, resulting in a more consistent taste in every cup of coffee.

[0047] See Figure 3 and Figure 6As shown, the filter sheet 6 covers the second coffee flow channel 53, and a third sealing ring 73 is provided between the filter sheet 6 and the secondary extraction guide 5. The filter sheet 6 is densely covered with filter holes, which plays an important role in intercepting fine coffee grounds. Covering the second coffee flow channel 53 ensures that all coffee liquid flowing through this area must pass through the sheet for filtration. The third sealing ring 73 is located on the periphery of the second coffee flow channel 53, further enhancing the sealing around the filter sheet 6. This ensures that the coffee liquid can only pass through the effective filtration area of ​​the filter sheet 6, eliminating the possibility of coffee liquid bypassing the filter sheet 6 from the edge gaps and flowing directly into the flow channel. This maximizes the comprehensive and fine filtration of the coffee liquid, allowing the finished coffee to reach a higher standard of purity and a delicate, flavorful taste.

[0048] The capsule coffee brewing cup and water inlet base feature a separate design. The outer wall of the upper cup body 1 has a snap-fit ​​protrusion 15 that rotates and engages with the water inlet base. When using the capsule coffee brewing cup, the user simply rotates the upper cup body 1 gently relative to the water inlet base, and the snap-fit ​​protrusion 15 quickly finds and engages with the matching slots and other structures of the water inlet base, achieving precise positioning and a secure connection. Compared to some plug-in or difficult-to-align connection methods, this rotating snap-fit ​​design significantly saves operation time, especially in situations where users are in a hurry in the morning. Users can quickly assemble the brewing cup and water inlet base and immediately begin the coffee brewing process, improving ease of use.

[0049] Preferably, the top surface of the upper cup body 1 is provided with multiple rotating grooves 16. When rotating the brewing cup to connect with the water inlet base, the user's fingers are placed in the rotating grooves 16, and the surface of the grooves significantly increases the friction compared to the smooth cup top. Whether the hands are dry or slightly wet, it provides a reliable point of force for the fingers, allowing the user to firmly grip the cup body and avoid slipping, which would prevent precise control of the rotation force and direction. This ensures that each rotation action can efficiently and stably advance the engagement process between the latching protrusion 15 and the water inlet base, improving the success rate and smoothness of the operation.

[0050] The spiked tray 4 is fixed to the primary extraction guide 3 by a screw 8 in the middle of the plate 41. The spiked tray 4 plays a key role in piercing the bottom of the coffee capsule during the coffee capsule brewing process. It is fixed to the primary extraction guide 3 by the screw 8, which can form a very stable connection structure.

[0051] The filter sheet 6 plays an important role in intercepting coffee grounds and ensuring the purity of the coffee liquid. It is fixed to the secondary extraction guide 5 with two screws 8, which ensures that it remains in the correct position during frequent coffee extraction processes and will not shift, deform or lift due to water flow impact, the force generated by coffee liquid flow, or external force interference during cleaning.

[0052] In fact, the structure of the capsule coffee brewing cup provided by this utility model can be adapted to Lavazza BLUE capsules and Lavazza A MODOMIO capsules, but a brewing cup specifically adapted to Lavazza BLUE capsules (such as...) Figure 7 (as shown) and a brewing glass specifically designed for Lavazza A MODOMIO capsules (such as...) Figure 1 and Figure 2 The difference (as shown) lies in the height of the upper glass 1, resulting in a different depth of the capsule-containing cavity 11. The brewing glass specifically designed for Lavazza BLUE capsules is taller than the brewing glass specifically designed for Lavazza A MODOMIO capsules.
