Description

Technical Field

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

[0002] In existing capsule coffee machines, the capsule coffee brewing container is one of the core components. Traditional capsule coffee brewing containers typically adopt an integrated design, mainly consisting of a base, a water inlet flip-top structure, and a brewing cup integrally molded with the base. This integrated design approach has certain rationality at specific stages of development; for example, in the early stages of product development, it can ensure the stability and sealing of the overall structure of the brewing container, providing a basic guarantee for stable coffee brewing.

[0003] However, with the continuous segmentation and diversification of the coffee market, coffee capsules have become increasingly diverse. Different brands, origins, and even roasting processes result in variations in shape, size, and required brewing environments, all in pursuit of the ultimate flavor. This means that coffee machines often need multiple capsule brewing boxes—typically five to six—to achieve precise matching and high-quality brewing when faced with such a wide variety of capsules.

[0004] In-depth analysis revealed a significant amount of structural overlap among these numerous brewing boxes. Specifically, the base and flip-top sealing structure are essentially the same across different types of brewing boxes. The only key difference lies in the structural design of the brewing cups. These different brewing cups vary in details such as internal volume, puncture structure, and extraction channel structure, depending on the characteristics of different capsules, to meet the brewing requirements of specific capsules.

[0005] From a manufacturing perspective, this traditional integrated and multi-model parallel brewing box production model results in higher production costs. These additional costs are inevitably passed on to the product price, affecting the market competitiveness of capsule coffee machines.

[0006] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a capsule coffee brewing box and a coffee machine, which aims to reduce the production cost of multiple capsule coffee brewing boxes configured in the coffee machine by leveraging the advantages of detachable brewing cup and base and flexible replacement of brewing cup.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A capsule coffee brewing box includes a base, a water inlet flip-top assembly flipped and connected to the base, and a brewing cup detachably connected to the base. The base has an overlapping step in the middle, and the top sidewall of the brewing cup protrudes outward to form an overlapping ring that presses against the overlapping step. The overlapping step has a through hole in the middle for the body of the brewing cup to pass through. The body of the brewing cup is rotatably snapped into the overlapping step by a snap-fit ​​structure. The brewing cup has a capsule cavity and a coffee outlet at the bottom. The capsule cavity has a puncture structure that pierces the bottom of the capsule. The water inlet flip-top assembly is used to seal and cover the capsule cavity and puncture the capsule to allow water to be injected.

[0010] As a further improvement to the above technical solution, the snap-fit ​​structure includes a snap-fit ​​protrusion on the outer wall of the brewing cup and a screw-fit groove corresponding to the through hole of the overlapping step.

[0011] As a further improvement to the above technical solution, the buckle protrusion is provided with a positioning protrusion, and the screw-on groove of the brewing cup is provided with a resistance recess that cooperates with the positioning protrusion. The resistance recess provides resistance to the positioning protrusion in the unlocking direction.

[0012] As a further improvement to the above technical solution, the top surface of the overlapping ring is provided with a plurality of rotating slots, and the overlapping step is provided with a clearance slot that is the same number as the rotating slots and corresponds one-to-one.

[0013] As a further improvement to the above technical solution, the top surface of the overlapping ring is provided with snap-fit ​​guidance markings.

[0014] As a further improvement to the above technical solution, the water inlet flip cover assembly includes a flip cover, a sealing outer cover fixed on the flip cover, a sealing inner cover, and a spiked sheet metal. The sealing inner cover and the spiked sheet metal are located inside the sealing outer cover, and a water inlet channel is provided in the middle of the flip cover.

[0015] As a further improvement to the above technical solution, the lower spike structure includes a plate and a plurality of conical spikes spaced apart on the plate. The conical spikes are hollowed out and the lower part of the conical spikes is connected to the coffee outlet through an extraction channel.

[0016] As a further improvement to the above technical solution, the lower spike structure is a vertically upward-pointing piercing tube, the bottom end of which is connected to the coffee outlet through the extraction channel.

[0017] As a further improvement to the above technical solution, the lower spike structure includes a vertically upward spike, the spike being hollowed out and the bottom end of the spike communicating with the coffee outlet through the extraction channel.

[0018] A coffee machine is also provided, including a main unit and the aforementioned capsule coffee brewing cartridge, which is mounted on the main unit.

[0019] The beneficial effects of this utility model are as follows: Compared with traditional capsule coffee machines, which often require multiple complete brewing boxes to accommodate various coffee capsules, the capsule coffee brewing box provided by this utility model has the advantages of detachable brewing cups and bases, and flexible replacement of brewing cups. The base and water inlet flip-top assembly can be designed as universal parts, and only one set needs to be configured for each coffee machine. There is no need to repeatedly manufacture these common structures for different capsules. We can focus on the efficient production and research and development of different brewing cups, which greatly reduces the amount of material procurement and inventory pressure, significantly reduces raw material costs, and optimizes the allocation of production resources.

[0020] Coffee machines equipped with the aforementioned capsule coffee brewing cassettes possess all the advantages of capsule coffee brewing cassettes, resulting in reduced overall production costs and enhanced market competitiveness. Attached Figure Description

Detailed Implementation

[0029] This utility model provides a capsule coffee brewing box and a coffee machine. 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.

[0030] Please see Figures 1 to 4 As shown, this utility model provides a capsule coffee brewing box, including a base 1, a water inlet flip-top assembly 2 connected to the base 1, and a brewing cup 3 detachably connected to the base 1. The base 1 forms an overlapping step 11 in the middle. The top side wall of the brewing cup 3 protrudes outward to form an overlapping ring 31 that presses against the overlapping step 11. The overlapping step 11 has a through hole 12 in the middle for the body of the brewing cup 3 to pass through. The body of the brewing cup 3 is rotatably snapped into the overlapping step 11 by a snap-fit ​​structure. The brewing cup 3 has a capsule cavity 34 and a coffee outlet 32 ​​located at the bottom. The capsule cavity 34 has a lower pointed structure that pierces the bottom of the capsule. The water inlet flip-top assembly 2 is used to seal and cover the capsule cavity 34 and pierce the capsule to inject water.

[0031] When using this capsule coffee brewing box, the first step is assembly. Place the brewing cup 3 on the base 1, so that the overlapping ring 31 of the brewing cup 3 hangs on the overlapping step 11 of the base 1, and the cup body of the brewing cup 3 passes downward through the hole 12. Then, the brewing cup 3 is rotated at a certain angle relative to the overlapping step 11 until the locking structure is firmly locked, realizing a reliable connection between the brewing cup 3 and the base 1, and preventing the brewing cup 3 from detaching from the base 1 during operation.

[0032] When starting the brewing process, carefully place the appropriate coffee capsule into the capsule chamber 34 of the brewing cup 3. Then proceed as follows... Figure 7 As shown, when the water inlet flap assembly 2 is closed, it not only precisely covers and seals the capsule cavity 34, preventing liquid leakage during brewing, but also precisely punctures the top of the capsule with its built-in piercing component. Simultaneously, the lower pointed piercing structure inside the brewing cup 3 punctures the bottom of the capsule, thus creating a complete water flow channel. The external water injection device begins to operate, and the water flows smoothly into the capsule cavity 34 under pressure, flowing through the capsule from all directions, fully saturating the coffee powder, and efficiently completing the extraction process. Finally, the extracted coffee liquid flows smoothly out through the coffee outlet 32 ​​at the bottom of the brewing cup 3, completing the brewing process of a cup of coffee.

[0033] Compared to existing technologies, traditional capsule coffee machines often require multiple complete brewing containers to accommodate various coffee capsules. However, thanks to the detachable brewing cup 3 and base 1, and the flexibility and interchangeability of the brewing cup 3, the base 1 and water inlet flip-top assembly 2 can be designed as universal components. Only one set is needed per coffee machine, eliminating the need to repeatedly manufacture these common structures for different capsules. This significantly reduces material procurement and inventory pressure, substantially lowers raw material costs, and optimizes production resource allocation. The focus can then be placed on the efficient production and development of different brewing cups 3, thereby reducing the overall production cost of the coffee machine and enhancing its market competitiveness.

[0034] Specifically, the snap-fit ​​structure includes a snap-fit ​​protrusion 33 on the outer wall of the brewing cup 3 and a screw-fit groove 13 corresponding to the through hole 12 of the overlapping step 11. The screw-fit groove 13 includes a notch 131 for inserting and removing the snap-fit ​​protrusion 33 and an arc-shaped groove 132 provided next to the notch 131.

[0035] When assembling the brewing cup 3 and the base 1, first align the body of the brewing cup 3 with the through hole 12 on the overlapping step 11 formed by the downward slope in the middle of the base 1, allowing the body of the brewing cup 3 to pass smoothly through the through hole 12. At this time, the snap-fit ​​protrusion 33 on the outer wall of the brewing cup 3 comes to the notch 131 of the screw-fit groove 13. Due to the presence of the notch 131, the snap-fit ​​protrusion 33 can enter its corresponding position area without obstruction. Next, manually apply a certain rotational force to the brewing cup 3, causing the snap-fit ​​protrusion 33 to slide into the arc-shaped groove 132 in the direction of rotation. The shape and size of the arc groove 132 are carefully designed. On the one hand, it can tightly accommodate the buckle protrusion 33, giving it a stable limit. On the other hand, its arc structure can make full use of the mechanical characteristics of the rotation process, so that the buckle protrusion 33 and the arc groove 132 form a mutually restrictive snap-fit ​​relationship after rotating at a certain angle, thereby firmly fixing the brewing cup 3 on the base 1, ensuring that the brewing cup 3 is stable in position during the subsequent coffee brewing process, and will not be displaced, shaken or fall off.

[0036] When it is necessary to disassemble the brewing cup 3 for cleaning, replacement or maintenance, rotate the brewing cup 3 in the opposite direction and the buckle protrusion 33 will slide in the opposite direction along the arc groove 132 until it returns to the notch 131 position. At this time, the brewing cup 3 can be easily removed from the base 1, which is convenient and efficient.

[0037] This snap-fit ​​design greatly simplifies the connection and separation process between the brewing cup 3 and the base 1. Users do not need complicated tools or professional skills; they can assemble or disassemble the cup with a simple rotation. This is ideal for home users who frequently change different types of brewing cups 3 to accommodate various coffee capsules, significantly improving operating speed, reducing manual labor time, increasing overall work efficiency, and lowering time costs.

[0038] In this embodiment, two snap-fit ​​protrusions 33 are provided, and correspondingly, two screw-fit grooves 13 are provided. The two snap-fit ​​protrusions 33 and the corresponding screw-fit grooves 13 allow for a more stable and balanced connection between the brewing cup 3 and the base 1. During the coffee brewing process, when faced with complex external forces such as water flow impact, internal pressure fluctuations, and slight vibrations from machine operation, the two symmetrically distributed snap-fit ​​protrusions 33 work together from different directions to effectively disperse stress, preventing local loosening or displacement caused by excessive force at a single point, ensuring stable brewing conditions, and thus improving the consistency of coffee extraction quality.

[0039] Further details can be found here. Figure 1 and Figure 2 As shown, the buckle protrusion 33 is provided with a positioning protrusion 35, and the screw-fit groove 13 of the brewing cup 3 is provided with a resistance recess 14 that cooperates with the positioning protrusion 35. The resistance recess 14 provides resistance to the positioning protrusion 35 in the unlocking direction. The resistance provided by the resistance recess 14 to the positioning protrusion 35 can effectively prevent the buckle protrusion 33 from accidentally loosening or rotating in the opposite direction due to external force, which greatly enhances the stability of the base 1 and the brewing cup 3 after they are engaged.

[0040] See Figure 4 As shown, the top surface of the overlapping ring 31 has multiple rotating grooves 311, and the overlapping step 11 has the same number of corresponding clearance grooves 111. This design provides clear and explicit operational guidance for users when installing and disassembling the brewing cup 3. When rotating the brewing cup 3 to connect or separate it from the base 1, fingers can be precisely placed in the rotating grooves 311 to apply force, avoiding slippage and ensuring that each rotation is accurately and efficiently transmitted to the locking structure, allowing the buckle protrusion 33 to smoothly enter or disengage from the rotating locking groove 13, significantly improving operational accuracy and reducing component wear or incorrect installation caused by improper force application.

[0041] Even better, the top surface of the overlapping ring 31 is provided with a snap-fit ​​guidance mark 312. For users who are using the capsule coffee machine for the first time or are unfamiliar with the brewing container installation and disassembly process, the snap-fit ​​guidance mark 312 clearly and intuitively shows the correct operating direction and key docking positions. Users do not need to spend a lot of time studying the instruction manual or trying repeatedly; they can quickly understand how to accurately dock the brewing cup 3 with the base 1 and in which direction to rotate it to successfully complete the snap-fit ​​action simply by observing the mark. This makes the operation simple and efficient, lowers the threshold for product use, and improves the user experience.

[0042] In this embodiment, see Figure 1As shown, the water inlet flip-top assembly 2 includes a flip-top 21, a sealing outer cover 22 fixed to the flip-top 21, a sealing inner cover 23, and a spiked sheet metal 24. The sealing inner cover 23 and the spiked sheet metal 24 are located inside the sealing outer cover 22. A water inlet channel 25 is provided in the middle of the flip-top 21. The spiked sheet metal 24 is cleverly integrated into the sealing outer cover 22, forming a piercing system that echoes the lower spiked structure inside the brewing cup 3. When the flip-top 21 is closed, the spiked sheet metal 24 precisely pierces the top of the coffee capsule, working synchronously with the lower spiked structure to instantly open a smooth liquid channel inside the capsule, ensuring that the water flows evenly and quickly to moisten the coffee powder, achieving efficient extraction. The outer sealing cap 22 and the inner sealing cap 23 work together to create a double-layer sealing protection for the capsule cavity 34, ensuring that the pressure inside the capsule cavity 34 is maintained stably within the ideal range. This avoids insufficient extraction due to pressure leakage caused by poor sealing, and preserves the original flavor and aroma of the coffee to the greatest extent, ensuring that every cup of coffee reaches the high-quality standard of being rich, full-bodied, and delicate in taste.

[0043] See Figure 4 As shown, to adapt the brewing cup 3 to Caffitaly capsules, a bottom-piercing structure is provided. Specifically, the bottom-piercing structure includes a vertically upward-pointing spike 55. The spike 55 is hollowed out, and its bottom end is connected to the coffee outlet 32 ​​through the extraction channel. The spike 55 and the coffee outlet 32 ​​are coaxially arranged, creating a stable and efficient coffee liquid discharge path. The length, diameter, and sharpness of the spike 55 are precisely designed to ensure accurate force application and stable piercing in one go upon contact with the bottom of the capsule, avoiding deviation or slippage. This allows the brewing cup 3 to seamlessly connect to the Caffitaly capsule without the need for additional cumbersome adjustments.

[0044] See Figure 5As shown, to adapt the brewing cup 3 to Lavazza BLUE and Lavazza AMODOMIO capsules, a bottom-piercing structure is provided. Specifically, this structure includes a plate 51 and multiple conical spikes 52 spaced apart on the plate 51. The conical spikes 52 are hollowed out, and their lower surfaces are connected to the coffee outlet 32 ​​via extraction channels. Specifically, the bottom surface of the plate 51 has seepage ports that correspond one-to-one with the number of spikes 55. The conical surfaces of the spikes 52 have multiple seepage grooves 53 that communicate with these seepage ports. These seepage ports are connected to the coffee outlet 32 ​​via extraction channels. This innovative design, where the seepage ports communicate with the seepage grooves 53 on the conical surfaces of the spikes 52, creates a comprehensive, three-dimensional coffee liquid seepage network. The moment the capsule is punctured, water rapidly flows through the permeation channel 53 and is evenly distributed throughout the capsule's interior, preventing localized water accumulation or extraction dead zones. This ensures that the coffee grounds and water come into full and even contact, maximizing the extraction of oils, aromas, and flavor compounds. Compared to traditional single-hole or simple puncture structures, this multi-channel permeation design significantly improves extraction efficiency and quality, allowing every cup of coffee to release the rich aroma and full-bodied taste characteristic of the Lavazza series capsules, catering to coffee lovers' pursuit of ultimate flavor and enhancing the product's core competitiveness.

[0045] See Figure 6 As shown, to adapt the brewing cup 3 to K-CUP capsules, a downward-pointing puncture structure is provided. Specifically, the downward-pointing puncture structure is a vertically upward-pointing puncture tube 54, the bottom end of which is connected to the coffee outlet 32 ​​through the extraction channel. The puncture tube 54, as the sole puncture and water inlet channel 25, strictly limits the path and rate of water flow into the capsule. Combined with the stable flow-limiting and pressure-controlling capabilities of the extraction channel, it comprehensively controls the pressure balance within the capsule. From the sudden pressure change at the initial puncture to the dynamic pressure adjustment during continuous extraction, the entire system works closely together to prevent internal pressure imbalances caused by external water pressure fluctuations or individual capsule differences, ensuring that the coffee powder is always in an ideal extraction pressure environment, accurately releasing flavor compounds and maintaining high-quality product output.

[0046] This utility model also provides a coffee machine, including a main unit and the aforementioned capsule coffee brewing cartridge, which is mounted on the main unit. The main unit, paired with a universal capsule coffee brewing cartridge, greatly simplifies the manufacturing process. The main unit production line does not need frequent adjustments to adapt to the complex and ever-changing integrated brewing cartridge structure, allowing for a focus on core function enhancement. The brewing cartridge, through a shared base 1 and water inlet flip-top assembly 2, only requires customized brewing cups 3 for different capsules, significantly reducing mold development costs, raw material inventory costs, and production assembly time, thereby lowering overall production costs and enhancing the product's competitiveness and attractiveness in the market.

[0047] This coffee machine, equipped with this capsule brewing cartridge, boasts excellent capsule compatibility. Given the current abundance of various capsules on the market, it's compatible with many well-known brands and types, such as different series from Lavazza, K-CUP, and Caffitaly. Users are not limited by the type of capsules that come with the machine; they can easily switch between different origins, flavor profiles, and roast levels at home to meet the diverse coffee preferences of family members.
