[0002] Coffee is a popular beverage, and coffee machines used for extraction are generally large, suitable for home or fixed locations, but inconvenient to carry and use. In contrast to bulky coffee machines, coffee cups with extraction functions are small and easy to use.

[0032] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0033] The specific embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0034] Reference Figure 1-4This utility model provides a leak-proof coffee cup, including a centrifuge chamber 20, a lid 120, a cup body 10, a water pump 50, and pipes. Specifically, the pipes include a first pipe 51 and a second pipe 52. The lid 120 covers the opening of the centrifuge chamber 20. The water pump 50 is connected to the first pipe 51 and is mounted on the lid 120. The first end of the first pipe 51 passes through the lid 120 and extends into the centrifuge chamber 20. The second end of the first pipe 51 is detachably connected to the first end of the second pipe 52. A liquid storage chamber 101 is formed inside the cup body 10. The second pipe 52 is located on one side of the cup body 10, and the second end of the second pipe 52 communicates with the liquid storage chamber 101. The cup body 10 is provided with a first contact point 11. The centrifuge chamber 20 is detachably installed inside the cup body 10, and the water pump 50 is electrically connected to or disconnected from the first contact point 11. The water pump 50 can be a peristaltic pump, which is compact and more hygienic.
[0035] Before extraction, refer to Figure 2 First, remove the centrifuge chamber 20 and the lid 120 from the cup body 10. At this time, the first pipe 51 and the second pipe 52 are disconnected, and the first contact 11 is disconnected from the water pump 50. Pour water into the liquid storage chamber 101, and place the coffee powder in the inner chamber; refer to Figure 1 Then, the inner chamber is installed into the cup body 10. At this time, the first pipe 51 is connected to the second pipe 52, and the first contact 11 is connected to the water pump 50. Figure 3 When the centrifuge chamber 20 rotates at high speed, the coffee powder inside is thrown against the side wall of the centrifuge chamber 20 under the action of centrifugal force. At the same time, water in the liquid storage chamber 101 is introduced into the centrifuge chamber 20 by the water pump 50 through the first pipe 51 and the second pipe 52 to mix with the coffee powder. The centrifuged extracted coffee liquid overflows from the opening of the centrifuge chamber 20 and flows into the liquid storage chamber 101. (Combined with 2...) Figure 3 During the extraction process, if the user accidentally removes the centrifuge chamber 20 from the cup body 10, the water pump 50 installed on the cup lid 120 will disconnect from the first contact 11 and will no longer draw water from the storage chamber 101. This prevents the liquid in the storage chamber 101 from spraying out from the second end of the second pipe 52 after the first pipe 51 and the second pipe 52 are disconnected, thus avoiding liquid leakage and preventing water from splashing.
[0036] Reference Figures 2-4 In one embodiment, the leak-proof coffee cup includes an extraction chamber 40, which is detachably installed within the cup body 10. Figure 7 , Figure 8The extraction chamber 40 includes a first chamber 410 and a second chamber 420 connected vertically. The first chamber 410 is fitted around the periphery of the centrifuge chamber 20, and the cup lid 120 covers the openings of the centrifuge chamber 20 and the first chamber 410. An extraction gap is left between the inner wall of the first chamber 410 and the outer wall of the centrifuge chamber 20. A through hole 411 is formed on the bottom wall of the first chamber 410, and the through hole 411 communicates with the liquid storage chamber 101. The second chamber 420 is located below the centrifuge chamber 20, and a drive mechanism 30 is provided inside the second chamber 420. The drive mechanism 30 is drively connected to the centrifuge chamber 20. By setting the extraction chamber 40 to fit around the periphery of the centrifuge chamber 20, the drive mechanism 30 can be drively connected to the centrifuge chamber 20. The coffee liquid extracted by the centrifuge chamber 20 overflows from its opening, flows into the first chamber 410 along the extraction gap, and then flows into the liquid storage chamber 101 through the through hole 411. (Refer to...) Figure 2 When it is necessary to add water or pour out coffee liquid, the extraction chamber 40 and its internal drive mechanism 30, centrifugal chamber 20 and cup lid 120 are removed from the cup body 10 to expose the liquid storage chamber 101. Then, water is injected into the liquid storage chamber 101 or the coffee liquid in the liquid storage chamber 101 is poured out.
[0037] Furthermore, a mounting plate is provided at the opening of the second compartment 420 to enclose the drive mechanism 30 within the second compartment 420. The output shaft of the drive mechanism 30 extends out of the mounting plate and connects to the centrifuge compartment 20. (Refer to...) Figure 7 Optionally, a heat insulation component 440 is also provided above the mounting plate to prevent the heat from the drive mechanism 30 from being conducted into the centrifugal chamber 20 and affecting the taste of the coffee liquid.
[0038] Reference Figure 8 In one embodiment, the opening of the second chamber 420 is provided with a baffle 415 protruding into the first chamber 410. The bottom wall of the first chamber 410 is inclined, and the bottom wall of the first chamber 410 and the baffle 415 form a flow channel 416, with the through hole 411 located at the lowest point of the flow channel 416. A mounting plate is pressed against the baffle 415, preventing coffee liquid from flowing into the second chamber 420. Through the inclined flow channel 416, the coffee liquid flows along the flow channel 416 to the through hole 411 and enters the liquid storage chamber 101. Optionally, a filter 430 can also be provided in the first chamber 410 of the extraction chamber 40 to further filter the extracted coffee liquid and improve the taste of the coffee liquid.
[0039] Reference Figure 7 , Figure 8In one embodiment, the outer side of the first chamber 410 has a mounting base 413, and the mounting base 413 is provided with a quick-connect connector 43. The first pipe 51 and the second pipe 52 are connected through the quick-connect connector 43. Further, the mounting base 413 is also provided with a second contact 44, and the water pump 50 is electrically connected to the first contact 11 through the second contact 44. When the extraction chamber 40, the centrifugation chamber 20 and the cup lid 120 are removed from the cup body 10, the quick-connect connector 43 is quickly disconnected from the second pipe 52, the first contact 11 is quickly disconnected from the second contact 44, the water pump 50 stops running, and no longer draws liquid from the storage chamber 101, thus preventing liquid from spraying out from the second pipe 52. When the extraction chamber 40, centrifuge chamber 20 and cup lid 120 are installed inside the cup body 10, the quick-connect connector 43 is quickly connected to the second pipe 52, and the first contact 11 and the second contact 44 are quickly electrically connected. After the water pump 50 is started, the liquid in the storage chamber 101 can be drawn into the centrifuge chamber 20 for coffee extraction.
[0040] Reference Figure 3 In one embodiment, the cup lid 120 includes an outer lid 121, a mounting lid 122, and an inner lid 123. A receiving cavity is formed above the mounting lid 122, and the water pump 50 and the first pipe 51 are installed within the receiving cavity. The outer lid 121 covers the outside of the receiving cavity. The mounting lid 122 covers the opening of the first chamber 410. The inner lid 123 covers the opening of the centrifuge chamber 20. The water pump 50 and the first pipe 51 are encapsulated within the receiving cavity by the outer lid 121. A locking member 1211 is provided on the outer lid 121, and a locking hole 412 is provided on the first chamber 410. By engaging the locking member 1211 with the locking hole 412, the outer lid 121 and the mounting lid 122 are locked onto the extraction chamber 40, thus sealing the centrifuge chamber 20 and the extraction chamber 40 and preventing liquid leakage. A first bearing is provided between the inner cover 123 and the mounting cover 122, and the inner cover 123 and the mounting cover 122 are rotatably connected. During the centrifugal extraction process, the centrifugal chamber 20 and the inner cover 123 can rotate synchronously relative to the mounting cover 122 and the extraction chamber 40 through the first bearing.
[0041] In one embodiment, the mounting base 413 has a shaft hole 4132, and the mounting cover 122 has a shaft hole 1222. A rotating shaft 42 passes through the shaft hole 4132 and the shaft hole 1222. Through the engagement of the rotating shaft 42 with the shaft hole 4132 and the shaft hole 1222, the outer cover 121 and the mounting cover 122 are rotatably connected to the extraction chamber 40. Figure 3 That is, the outer cover 121 and the mounting cover 122 can be flipped relative to the extraction chamber 40, thereby opening or closing the extraction chamber 40 and the centrifugation chamber 20.
[0042] Reference Figure 5In one embodiment, the inner wall of the first chamber 410 extends upward along the outer wall of the centrifuge chamber 20 to a first position 4102, and the cover wall of the inner cover 123 extends downward along the outer wall of the centrifuge chamber 20 to a second position 1232. The height of the first position 4102 is higher than the height of the second position 1232. The portion of the inner wall of the first chamber 410 from the first position 4102 to the second position 1232 is a first leak-proof section 4104, and the inner diameter of the first leak-proof section 4104 gradually decreases from the first position 4102 to the second position 1232. The outer wall of the mounting cover 122 is provided with a second leak-proof section 1224 that matches the first leak-proof section 4104. Because the coffee liquid ejected from the opening of the centrifuge chamber 20 flows out along its outer wall, and the centrifuge chamber 20 rotates at high speed during centrifugal extraction, setting the height of the first position 4102 higher than the second position 1232 causes the inner wall of the first chamber 410 to overlap and interweave with the cover wall of the inner cover 123, thus completely surrounding the outer wall of the centrifuge chamber 20. The inner diameter of the first leak-proof section 4104 gradually decreases from the first position 4102 to the second position 1232, forming a funnel shape. This ensures that the extracted coffee liquid can only flow along the extraction gap to the bottom wall of the first chamber 410, and then into the storage chamber 101, preventing coffee liquid leakage. Furthermore, the cover wall of the mounting cover 122 is provided with a second leak-proof section 1224 that matches the upper section of the first leak-proof section 4104. Through the cooperation of the first leak-proof section 4104 and the second leak-proof section 1224, the opening of the first chamber 410 is better sealed.
[0043] Furthermore, referring to Figure 3 , Figure 4 , Figure 7 , Figure 8 In one embodiment, the upper outer periphery of the first chamber 410 has a flange 414, which is placed at the top of the cup wall of the cup body 10. The space between the outer wall of the second chamber 420 and the inner wall of the cup body 10 forms the liquid storage cavity 101. By placing the flange 414 at the top of the cup wall of the cup body 10, the extraction chamber 40 is suspended and pressed into the cup body 10. This facilitates the formation of the liquid storage cavity 101 by leaving space between the outer wall of the second chamber 420 and the inner wall of the cup body 10, and also seals the opening of the cup body 10 by the flange 414, preventing liquid from overflowing from the liquid storage cavity 101. A sealing ring 41 is fitted on the outer wall of the first chamber 410 to seal the first chamber 410 with the inner wall of the cup body 10, further preventing liquid from overflowing from the liquid storage cavity 101.
[0044] In one embodiment, the first pipe 51 includes an inlet section 511, an outlet section 512, and a nozzle section 513. One end of the inlet section 511 is connected to the quick-connect fitting 43, and the other end is connected to the inlet of the water pump 50. One end of the outlet section 512 is connected to the outlet of the water pump 50, and the other end is connected to the nozzle section 513. The nozzle section 513 extends through the cup lid 120 into the centrifuge chamber 20. When the water pump 50 is started, the liquid in the storage chamber 101 flows into the inlet section 511 through the second pipe 52, then through the outlet section 512, and finally is sprayed into the centrifuge chamber 20 by the nozzle section 513, spraying onto the coffee powder being centrifuged inside the centrifuge chamber 20, thereby centrifuging and extracting coffee liquid. The lower part of the nozzle section 513 is provided with a spray hole with a diameter of less than 1mm, such as 0.4mm, 0.5mm, 0.6mm, etc. This allows for greater spray pressure, enabling the sprayed liquid to mix better with the coffee powder. Then, under the action of centrifugal force, the coffee liquid is extracted and thrown out from the opening of the centrifuge chamber 20, thereby improving the coffee extraction rate and extraction speed.
[0045] In one embodiment, the first tube further includes a straw section 514, and the water inlet section 511 is provided with a three-way connector 515, which communicates with the straw section 514. After extraction, the coffee liquid in the storage chamber 101 can be directly drawn out through the straw section 514, passing through the front of the water inlet section 511 and the three-way connector 515, for easy drinking. The top of the outer cover 121 is also provided with a flip cover 1212 that is flipped and connected thereto. Opening the flip cover 1212 exposes the straw section 514, making it easy for the user to drink.
[0046] In one embodiment, the leak-proof coffee cup further includes a shell 60, a handle 61, a control component 70, and a battery 80. The shell 60 is fitted over the cup body 10, the handle 61 is connected to one side of the shell 60, the control component 70 is disposed inside the handle 61, and the handle 61 is provided with a control switch 71 electrically connected to the control component 70. The battery 80 is disposed inside the shell 60, and the control component 70 is electrically connected to the first contact 11, the drive mechanism 30, and the battery 80. The control component 70 is strategically arranged within the space of the handle 61, and the coffee cup can be easily and quickly opened or closed by operating the control switch 71. The shell 60 houses and protects all components. The battery 80 provides power to the components, and the control component 70 controls the operation of the first contact 11, the drive mechanism 30, and the water pump 50.
[0047] Optionally, refer to Figure 9The centrifuge chamber 20 has an overflow groove 202 at the edge of its opening. The inner cover 123 seals the centrifuge chamber 20, preventing coffee powder from flying out during extraction. Simultaneously, the overflow groove 202 at the edge of the centrifuge chamber 20 allows the extracted coffee liquid to flow upwards along the overflow groove 202 and out of the centrifuge chamber 20 during centrifugal extraction. The overflow groove 202 has a small aperture, making it difficult for coffee powder to overflow.
[0048] Optionally, refer to Figure 6 The leak-proof coffee cup also includes a transmission mechanism 90 connected to the centrifuge chamber 20, and the centrifuge chamber 20 is connected to the drive mechanism 30 via the transmission mechanism 90. (See reference...) Figure 7 A transmission component 32 is connected to the output shaft of the drive mechanism 30, in conjunction with... Figure 6 A limiting hole 902 is provided on the transmission mechanism 90, and the transmission component 32 is disposed within the limiting hole 902. The power of the drive mechanism 30 is transmitted to the transmission mechanism 90 and the centrifuge chamber 20 via the transmission component 32, thereby driving the centrifuge chamber 20 to rotate. Specifically, the transmission component 32 is a polygonal component, and the limiting hole 902 is a polygonal hole. The transmission component 32 cooperates with the limiting hole 902 to drive the transmission mechanism 90 to rotate.
[0049] Furthermore, referring to Figure 7 In one embodiment, the leak-proof coffee cup further includes an elastic element 31. The elastic element 31 abuts against the top of the transmission element 32 and the transmission mechanism 90. In other embodiments, the elastic element 31 may also be disposed between the bottom of the drive mechanism 30 and the second compartment 420. The elastic space provided by the elastic element 31 prevents misalignment between the drive mechanism 30 and the transmission mechanism 90 due to errors during assembly, ensuring a better transmission connection between the drive mechanism 30 and the transmission mechanism 90.
[0050] Combination Figure 9Optionally, the centrifuge chamber 20 is equipped with a blade 21, which is connected to the transmission mechanism 90. The transmission mechanism 90 can be connected to or separated from the centrifuge chamber 20, allowing the centrifuge chamber 20 to have both grinding and extraction states. In the grinding state, the transmission mechanism 90 is separated from the centrifuge chamber 20, and the drive mechanism 30 drives the blade 21 to rotate in a first direction. The blade 21 rotates at high speed to pulverize the coffee beans in the centrifuge chamber 20. In the extraction state, the transmission mechanism 90 is connected to the centrifuge chamber 20, and the drive mechanism 30 drives the blade 21 and the centrifuge chamber 20 to rotate in a second direction. Under the action of centrifugal force, the coffee powder is thrown against the side wall of the centrifuge chamber 20. At the same time, water in the liquid storage chamber 101 is introduced into the centrifuge chamber 20 by the water pump 50 to collide and mix with the high-speed rotating coffee powder. The extracted coffee liquid overflows from the opening of the centrifuge chamber 20 and flows into the liquid storage chamber 101. The liquid in the liquid storage chamber 101 can be circulated back into the centrifuge chamber 20 to extract coffee, ultimately obtaining fully extracted coffee liquid. Through the flexible cooperation of the transmission mechanism 90, centrifuge chamber 20, and blade 21, the leak-proof coffee cup combines grinding and extraction functions. Furthermore, it extracts coffee using centrifugal force, resulting in a high extraction rate and superior coffee flavor. The nested arrangement of the cup body 10 and centrifuge chamber 20, with the centrifuge chamber 20 serving as both a grinding and extraction chamber, effectively saves space, making the overall coffee cup more compact, portable, and convenient to use.
[0051] Reference Figure 9 In one embodiment, the transmission mechanism 90 includes a base and a first engaging member 920. A first end of the base is connected to the cutter 21, and a second end of the base is connected to the first engaging member 920. A second engaging member 930 is provided at the bottom of the centrifuge chamber 20. In the grinding state, the first engaging member 920 and the second engaging member 930 are separated, meaning the base, the first engaging member 920, and the cutter 21 rotate in a first direction with the drive mechanism 30, while the second engaging member 930 and the centrifuge chamber 20 remain stationary. In the extraction state, the first engaging member 920 and the second engaging member 930 are engaged, meaning the base, the cutter 21, the first engaging member 920, the second engaging member 930, and the centrifuge chamber 20 are connected as a whole and rotate in a second direction with the drive mechanism 30.
[0052] Optionally, the blade 21 includes a screw and two cross-layered blades with a connecting hole in the middle. The screw passes through the connecting hole to lock the blades onto the base. One blade is bent downwards and the other is bent upwards, which increases the probability of the blades colliding with the coffee beans, improving the grinding efficiency, and also prevents the coffee beans from getting stuck between the blades and the bottom wall of the centrifuge chamber 20.
[0053] In one embodiment, the nozzle segment 513 is positioned above the middle of the blade 21 to avoid the path of the blade 21's rotation and prevent interference between them. In other embodiments, the nozzle segment 513 may be positioned near the lower part of the inner wall of the centrifuge chamber 20, so that the sprayed water can better mix with the coffee powder that is centrifuged and thrown towards the inner wall.
[0054] Specifically, in one embodiment, the base includes an upper cover 911, a base plate 912, and a boss 913, with one side of the base plate 912 connected to the boss 913. In this embodiment, the base plate 912 and the boss 913 are an integral structure. A second bearing 940 is fitted onto the boss 913. The first engaging member 920 is rotatably connected to the base plate 912. The bottom wall of the centrifuge chamber 20 protrudes inward to form a mounting platform 201, which has a mounting hole. The upper cover 911 covers the mounting platform 201 and is connected to the cutter 21. The boss 913 extends into the mounting hole and is connected to the upper cover 911. The upper cover 911 is located inside the centrifuge chamber 20 and covers the mounting platform 201, with its lower part protruding into the mounting hole and integrally connected to the boss 913. The area below the mounting forms an installation space. The base plate 912 is located below the bottom wall of the centrifuge chamber 20. The top cover 911 and the base plate 912 enclose the boss 913, the second bearing 940, and the first meshing member 920 within the installation space. The transmission mechanism 90 is confined to the centrifuge chamber 20, and its axial freedom is restricted. However, by providing the second bearing 940, the transmission mechanism 90 can rotate around the mounting platform 201 in the first direction.
[0055] Specifically, the first engaging member 920 is a toothed block, with a rotating hole at one end and pointed teeth at the other. A protruding post is provided on the base plate 912, and the toothed block is rotatably mounted on the protruding post through the rotating hole. A rotational clearance is provided between the protruding post and the boss 913. When the drive mechanism 30 drives the base and the first engaging member 920 to rotate in the first direction, the tip of the first engaging member 920 can rotate around the protruding post within the rotational clearance range. The tip of the first engaging member 920 does not get stuck on the second engaging member 930, and the two remain separated, preventing the centrifuge chamber 20 from rotating with it. The second engaging member 930 is a gear ring with multiple internal teeth, all facing the same direction. The gear ring is fixed to the wall of the mounting hole and located at the position corresponding to the first engaging member 920. When the toothed block rotates in the second direction, it can engage and lock with the internal teeth. Optionally, a spring is also abutting between the first engaging member 920 and the boss 913. Through the action of the spring, after the base rotates in the first direction, the first engaging member 920 can return to a specific position, ensuring that it can engage with the second engaging member 930 in the second direction.
[0056] Reference Figure 4Optionally, the coffee cup also includes a cooling mechanism 80, which is attached to the outer wall of the liquid storage chamber 101. The cooling mechanism 80 cools the liquid, exchanging heat with the liquid inside the cup body 10 to lower the temperature of the liquid in the storage chamber 101, thereby extracting a low-temperature coffee liquid, better preserving the rich flavor of the coffee, and satisfying the needs of those who prefer iced coffee. The cooling mechanism 80 is located inside the outer shell 60 and below the cup body 10. Furthermore, a heat-insulating material is provided between the outer shell 60 and the cup body 10 to prevent heat exchange between the liquid in the storage chamber 101 and the outside environment, which would affect the taste of the coffee. A heat-insulating material is also fitted around the second pipe 52 to prevent heat exchange between the liquid in the storage chamber 101 and the outside environment as it flows through the second pipe 52. After the coffee liquid extracted by the centrifuge chamber 20 overflows, it flows into the storage chamber 101. The water pump 50 repeatedly pumps the liquid in the storage chamber 101 into the centrifuge chamber 20 through the first pipe 51 and the second pipe 52 for multiple extractions. After this cycle is repeated many times, the liquid in the storage chamber 101 is cooled down more quickly, and cold brew or iced coffee liquid with a better taste can be made in a short time.
[0057] Specifically, in one embodiment, the cooling mechanism 80 includes a cooling element 810, a radiator 820, and a fan. The cooling element 810 is attached to the bottom wall of the cup body 10, and the radiator 820 is located on the side of the cooling element 810 away from the cup body 10. The fan blows air towards the radiator 820. When the cooling element 810 is activated, one side is the cold side and the other side is the hot side. The cold side exchanges heat with the cup body 10, and the heat from the hot side is dissipated outward by the radiator 820. The fan blows the heat out of the outer casing 60.
[0058] Optionally, in this embodiment, the fan includes a first fan 830 and a second fan 840, with the first fan 830 positioned below the heat sink 820. The heat sink 820 is annular, and the second fan 840 is positioned within the inner ring of the heat sink 820. The outer casing 60 has a first air vent 601 corresponding to the position of the first fan 830 and a second air vent 602 corresponding to the position of the heat sink 820. Specifically, the first fan 830 is an axial flow fan, and the second fan 840 is a blower. When the first fan 830 and the second fan 840 are activated, outside air enters the outer casing 60 through the first air vent 601, flows to the second fan 840, exchanges heat with the heat sink 820, and is finally blown out through the second air vent 602, carrying the heat out of the outer casing 60.
[0059] Optionally, in other embodiments, the fan includes a first fan 830 or a second fan 840, and one of the first air vent 601 and the second air vent 602 is adjusted to be an air inlet and the other an air outlet according to the heat dissipation effect. That is, heat dissipation is achieved through one of the fans to meet the needs of different products.
[0060] Furthermore, in one embodiment, the cooling mechanism 80 further includes a heat insulation plate 812 and a heat conducting plate 814, with the heat insulation plate 812 located between the heat conducting plate 814 and the bottom wall of the cup body 10. The cup body 10 is a metal cup, with one side of the cooling element 810 adhering to the outer surface of the bottom wall of the cup body 10. A clearance hole is provided in the middle of the heat insulation plate 812, and the other side of the cooling element 810 extends into the clearance hole. One side of the heat conducting plate 814 protrudes into the clearance hole and adheres to the cooling element 810, while the other side of the heat conducting plate 814 adheres to the radiator 820. The cold side of the cooling element 810 adheres to the bottom wall of the metal cup, exchanging heat with the cup body 10 to lower the temperature of the liquid inside the cup. The heat insulation plate 812 is placed outside the bottom wall of the metal cup to better maintain the temperature inside the cup. The hot side of the cooling chip 810 contacts the heat-conducting plate 814, transferring heat to the heat-conducting plate 814, and then dissipating it through the heat sink 820.
[0061] Furthermore, a temperature sensor is provided at the second end of the second pipe 52, and the temperature sensor is electrically connected to the control component 70. The temperature sensor detects the outlet water temperature of the liquid storage chamber 101, and the control component 70 controls the cooling element 810 according to the outlet water temperature, thereby timely detecting and adjusting the water temperature.
[0062] The leak-proof coffee cup of at least one of the above embodiments combines grinding and extraction functions, effectively preventing liquid leakage during the extraction process. It extracts coffee using centrifugal force, resulting in a high extraction rate and better coffee flavor. Furthermore, the nested arrangement of the cup body 10 and the centrifugal chamber 20, with the centrifugal chamber 20 serving as both a grinding and extraction chamber, effectively saves space, making the overall coffee cup more compact, portable, and convenient to use. During the coffee extraction process, the centrifugal chamber 20 rotates at high speed. During this centrifugal motion, the coffee liquid mixes with air, creating a layer of oily foam similar to a fluffy cake on the surface, further enhancing the flavor of the coffee.
