Description

Technical Field

[0001] This invention relates to the field of coffee equipment technology, and in particular to a coffee cup and a coffee making method. Background Technology

[0002] Coffee is a popular beverage, and coffee lovers prefer to brew their own coffee by freshly grinding beans for a richer, more aromatic experience. While there are many coffee machines on the market that can both grind and extract coffee beans, they are generally large and suitable for home or fixed locations, making them inconvenient to carry and use. Although coffee cups are smaller than coffee machines, most only allow brewing coffee grounds and lack grinding capabilities. Coffee cups that combine grinding and brewing are rare. They are typically brewed directly through a hot water filter, resulting in low extraction rates and a less desirable taste. Using cold water further reduces extraction rates and slows the brewing process. Summary of the Invention

[0003] Based on this, the present invention provides a coffee cup and a coffee making method, which are not only easy to carry and use, but also have a high extraction rate.

[0004] A coffee cup includes a cup body, a grinding chamber, a clutch mechanism, and a drive mechanism. The cup body is fitted over the grinding chamber.

After pulverization, the drive mechanism reverses, causing the clutch mechanism, cutting tool, and grinding chamber to rotate in a second direction. The coffee powder, under centrifugal force, is thrown against the side wall of the grinding chamber, colliding and mixing with water introduced into the chamber, extracting coffee liquid which overflows from the opening and flows into the cup. The liquid in the cup can be circulated back into the grinding chamber to extract more coffee, ultimately resulting in fully extracted coffee. Through the flexible cooperation of the clutch mechanism, grinding chamber, and cutting tool, the coffee cup combines grinding and extraction functions. Furthermore, the centrifugal extraction results in a high extraction rate and a better coffee flavor. The nested arrangement of the cup and grinding chamber, with the grinding chamber serving as both a grinding and extraction chamber, effectively saves space, making the coffee cup more compact, portable, and convenient to use.

[0043] 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.

[0044] The specific embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0045] Reference Figure 1-4 An embodiment of the present invention provides a coffee cup, including a cup body 10, a grinding chamber 20, a clutch mechanism 30, and a drive mechanism 40. The cup body 10 is sleeved outside the grinding chamber 20, and a liquid storage cavity 101 is formed inside the cup body 10; the liquid storage cavity 101 communicates with the grinding chamber 20. The drive mechanism 40 is connected to the clutch mechanism 30. A blade 21 is provided inside the grinding chamber 20, and the blade 21 is connected to the clutch mechanism 30. The clutch mechanism 30 can be connected to or separated from the grinding chamber 20, so that the grinding chamber 20 has a grinding state and an extraction state. In the grinding state, the clutch mechanism 30 is separated from the grinding chamber 20, and the drive mechanism 40 drives the blade 21 to rotate in a first direction. In the extraction state, the clutch mechanism 30 is connected to the grinding chamber 20, and the drive mechanism 40 drives the blade 21 and the grinding chamber 20 to rotate in a second direction. Specifically, the cup body 10 includes an openable cup body 110 and a cup lid 120, with the cup lid 120 covering the opening of the grinding chamber 20. The drive mechanism 30 may be an electric motor.

[0046] When using, refer to Figure 2 First, separate the grinding chamber 20 from the cup body 110 of the cup body 10. Pour water into the liquid storage chamber 101 of the cup body 10. Open the lid 120 and put coffee beans into the grinding chamber 20. Then close the lid 120 and install the grinding chamber 20 into the cup body 110 of the cup body 10, as per [reference needed]. Figure 1Then, the drive mechanism 40 is activated, causing the clutch mechanism 30 and the cutter 21 to rotate relative to the grinding chamber 20 in the first direction. The cutter 21 rotates at high speed to crush the coffee beans in the grinding chamber 20. After crushing, the drive mechanism 40 reverses, causing the clutch mechanism 30, the cutter 21 and the grinding chamber 20 to rotate in the second direction. Under the action of centrifugal force, the coffee powder is thrown towards the side wall of the grinding chamber 20. At the same time, the water in the liquid storage chamber 101 is introduced into the grinding chamber 20 to collide and mix with the high-speed rotating coffee powder. The extracted coffee liquid overflows from the opening of the grinding chamber 20 and flows into the liquid storage chamber 101. The liquid in the liquid storage chamber 101 can be circulated into the grinding chamber 20 to extract coffee, and finally, fully extracted coffee liquid is obtained. With the clutch mechanism 30 working flexibly with the grinding chamber 20 and the blade 21, the coffee cup has both grinding and extraction functions. It extracts coffee through centrifugal force, resulting in a high extraction rate and better coffee taste. Furthermore, by nesting the cup body 10 and the grinding chamber 20, the grinding chamber 20 serves as both a grinding and extraction chamber, effectively saving space. The overall size of the coffee cup is smaller, making it more portable and convenient to use.

[0047] Reference Figures 4-6 In one embodiment, the clutch mechanism 30 includes a base 310 and a first engaging member 320. A first end of the base 310 is connected to the cutter 21, and a second end of the base 310 is connected to the first engaging member 320. A second engaging member 330 is provided at the bottom of the grinding chamber 20. In the grinding state, the first engaging member 320 and the second engaging member 330 are separated, meaning the base 310, the first engaging member 320, and the cutter 21 rotate in a first direction with the drive mechanism 40, while the second engaging member 330 and the grinding chamber 20 remain stationary. In the extraction state, the first engaging member 320 and the second engaging member 330 are engaged, meaning the base 310, the cutter 21, the first engaging member 320, the second engaging member 330, and the grinding chamber 20 are connected as a whole and rotate in a second direction with the drive mechanism 40. Through the flexible cooperation of the first meshing member 320 and the second meshing member 330, the grinding chamber 20 is in different functional states when the drive mechanism 40 rotates in different directions, so that the same chamber can meet two functional requirements.

[0048] Reference Figure 6 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 310. One blade is bent downwards and the other is bent upwards, which increases the probability of the blades colliding with the coffee beans and improves the grinding efficiency, while also preventing the coffee beans from getting stuck between the blades and the bottom wall of the grinding chamber 20.

[0049] Reference Figure 6Specifically, in one embodiment, the base 310 includes an upper cover 311, a base plate 312, and a boss 313, with one side of the base plate 312 connected to the boss 313. In this embodiment, the base plate 312 and the boss 313 are an integral structure. A first bearing 340 is fitted onto the boss 313. The first engaging member 320 is rotatably connected to the base plate 312. The bottom wall of the grinding chamber 20 protrudes inward to form a mounting platform 201, which has a mounting hole. The upper cover 311 covers the mounting platform 201 and is connected to the cutting tool 21. The boss 313 extends into the mounting hole and is connected to the upper cover 311. The inner ring of the first bearing 340 is tightly fitted against the boss 313, and the outer ring of the first bearing 340 is tightly fitted against the mounting platform 201. During grinding, the boss 313, the upper cover 311, and the blade 21 can rotate more smoothly relative to the grinding chamber 20 in the first direction, ensuring that the blade grinds the coffee beans. (Refer to...) Figure 4 , 5 The upper cover 311 is located inside the grinding chamber 20 and covers the mounting platform 201. The lower part of the upper cover 311 protrudes into the mounting hole and is connected to the boss 313 as a whole. The area below the mounting platform 201 forms an installation space. The bottom plate 312 is located below the bottom wall of the grinding chamber 20. The upper cover 311 and the bottom plate 312 encapsulate the boss 313, the first bearing 340, and the first engaging member 320 within the installation space. The clutch mechanism 30 is confined to the grinding chamber 20, and its axial freedom is restricted. However, by setting the first bearing 340, the clutch mechanism 30 can rotate around the mounting platform 201 in the first direction.

[0050] Specifically, refer to Figure 4 , Figure 6 The first meshing member 320 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 312, 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 313. When the drive mechanism 40 drives the base 310 and the first meshing member 320 to rotate in the first direction, the tip of the first meshing member 320 can rotate around the protruding post within the rotational clearance range. The tip of the first meshing member 320 does not get stuck on the second meshing member 330, and the two remain separated, preventing the grinding chamber 20 from rotating with it. The second meshing member 330 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 meshing member 320. When the toothed block rotates in the second direction, it can mesh and lock with the internal teeth. Optionally, a spring is also abutting between the first engaging member 320 and the boss 313. Through the action of the spring, after the base 310 rotates in the first direction, the first engaging member 320 can return to a specific position, ensuring that it can engage with the second engaging member 330 in the second direction.

[0051] Reference Figure 2 , Figure 4, Figure 7 and Figure 8 In one embodiment, the coffee cup further includes an extraction chamber 50, which is fitted around the outer periphery of the grinding chamber 20. A drive mechanism 40 is installed inside the extraction chamber 50, and the extraction chamber 50 is detachably installed inside the cup body 10. A lid 120 is closable and covers the openings above the grinding chamber 20 and the extraction chamber 50, and the extraction chamber 50 is detachably installed inside the cup body 110. By fitting the extraction chamber 50 around the outer periphery of the grinding chamber 20, the drive mechanism 40 can be connected to the clutch mechanism 30 on the grinding chamber 20. (See reference...) Figure 2 When it is necessary to fill with water or pour out coffee liquid, the extraction chamber 50 and its internal drive mechanism 40, grinding chamber, clutch mechanism 30 and cup lid 120 are removed from the cup body 110 to expose the liquid storage chamber 101. Then, water is poured into the liquid storage chamber 101 or the coffee liquid in the liquid storage chamber 101 is poured out.

[0052] Reference Figure 7 , Figure 8 The extraction chamber 50 includes a first chamber 510 and a second chamber 520 connected vertically. The first chamber 510 is fitted around the outer periphery of the grinding chamber 20, with an extraction gap between the inner wall of the first chamber 510 and the outer wall of the grinding chamber 20. A through hole 511 is formed on the bottom wall of the first chamber 510, which communicates with the liquid storage chamber 101. By placing the first chamber 51 around the outer periphery of the grinding chamber 20, the coffee liquid extracted by the grinding chamber 20 overflows from its opening and flows into the first chamber 510 along the extraction gap, and then flows into the liquid storage chamber 101 through the through hole 511. This also prevents the high-speed rotating grinding chamber 20 from splashing the overflowing coffee liquid outward, thus preventing coffee liquid leakage. The second chamber 520 is located below the grinding chamber 20, corresponding to the location of the clutch mechanism 30. The drive mechanism 40 is disposed inside the second chamber 520, facilitating the transmission connection between the drive mechanism 40 and the clutch mechanism 30. Furthermore, an installation plate is provided at the opening of the second compartment 520 to enclose the drive mechanism 40 within the second compartment 520. The drive shaft of the drive mechanism 40 extends out of the installation plate and connects to the clutch mechanism 30. Optionally, a heat insulation component 540 is also provided above the installation plate to prevent the heat from the drive mechanism 40 from being conducted into the grinding chamber 20, thus affecting the taste of the coffee liquid.

[0053] Reference Figure 7In one embodiment, the opening of the second chamber 520 is provided with a baffle 512 protruding into the first chamber 510. The bottom wall of the first chamber 510 is inclined, and the bottom wall of the first chamber 510 and the baffle 512 form a flow channel 513. The through hole 511 is located at the lowest point of the flow channel 513. A mounting plate is pressed against the baffle 512, and the baffle 512 and the mounting plate prevent coffee liquid from leaking into the second chamber 520 and affecting the use of the drive mechanism. Through the inclined flow channel 513, the coffee liquid flows smoothly along the inclined direction of the flow channel 513 to the through hole 511, and then all of it enters the liquid storage chamber 101. (Refer to...) Figure 8 Optionally, a filter 530 can be installed in the first chamber 510 of the extraction chamber 50 to further filter the extracted coffee liquid and improve the taste of the coffee liquid.

[0054] Reference Figures 4-6 and Figure 8 In one embodiment, an elastic element 41 is provided between the top of the drive mechanism 40 and the clutch mechanism 30. Further, a transmission element 42 is connected to the output shaft of the drive mechanism 40, and a limiting hole 3102 is provided in the base. The transmission element 42 is disposed within the limiting hole 3102, and the elastic element 41 abuts against the top of the transmission element 42 between the base 310 and the drive mechanism 42. Specifically, the transmission element 42 is a polygonal element, and the limiting hole 3102 is a polygonal hole. The transmission element 42 engages with the limiting hole 3102, thereby driving the base 310 to rotate. In other embodiments, the elastic element 41 can also be disposed between the bottom of the drive mechanism 40 and the second compartment 520. The elastic space provided by the elastic element 41 prevents errors during assembly from causing improper installation of the drive mechanism 40 and the clutch mechanism 30, ensuring a better connection between the drive mechanism 40 and the clutch mechanism 30.

[0055] Furthermore, referring to Figure 3 and Figure 4In one embodiment, the coffee cup also includes a water pump 60 and a pipe. One end of the pipe is connected to the liquid storage chamber 101, and the other end extends into the grinding chamber 20. The water pump 60 is connected to the pipe. The water pump 60 draws water from the liquid storage chamber 101 into the grinding chamber 20 for coffee extraction. The water pump 60 can be a peristaltic pump, which is compact and more hygienic. The pipe includes a first pipe 61, a second pipe 62, and a third pipe 63 connected in sequence. The first end of the first pipe 61 extends into the liquid storage chamber 101, and the second end is a plug-in end 82. The first end of the second pipe 62 can be quickly plugged into the second end of the first pipe 61, and the second end of the second pipe 62 is connected to the inlet of the water pump 60. The first end of the third pipe 63 is connected to the outlet of the water pump 60, and the second end passes through the cup lid 120 and is inserted into the grinding chamber 20. The second end of the third pipe 63 is provided with a spray hole. When the water pump 60 is activated, the liquid in the storage chamber 101 flows from the first pipe 61 into the second pipe 62, then through the third pipe 63, and finally is sprayed into the grinding chamber 20 through the spray nozzle, mixing with the coffee powder inside. The nozzle diameter is less than 1 mm, such as 0.4 mm, 0.5 mm, or 0.6 mm, allowing for greater spray pressure and better mixing of the sprayed liquid with the coffee powder. Under centrifugal force, the coffee liquid is extracted and ejected from the opening of the grinding chamber 20, improving the coffee extraction rate and speed. In this embodiment, the third pipe 63 is positioned above the middle of the blade 21 to avoid interference with the blade's rotation path. In other embodiments, the third pipe 63 can also be positioned near the lower part of the inner wall of the grinding chamber 20, allowing the sprayed water to mix better with the coffee powder centrifugally thrown towards the inner wall.

[0056] Furthermore, the pipeline also includes a straw 64, the first end of which is connected to the second tube 62. After extraction is complete, the coffee liquid in the reservoir 101 can be directly drawn out through the straw 64 for easy drinking.

[0057] The second tube 62, the third tube 63, and the straw 64 are all located on the cup lid 120. When adding water or pouring out coffee, the second tube 62 can be quickly connected to or separated from the first tube 61.

[0058] Furthermore, the cup body 10 also includes a handle 81 connected to one side of the cup body 110, and the first pipe 61 extends from bottom to top along the handle 81. Optionally, the water pump 60 is disposed inside the handle 81. The space inside the handle 81 allows for the rational arrangement of the water pump 60 and pipes.

[0059] In other embodiments, the water pump 60 is disposed inside the cup lid 120, ensuring that after the cup lid 120 is removed from the cup body 110, the water pump 60 is disconnected from the first pipe 61, preventing water from spraying out from the second end of the first pipe 61 and causing water to splash. Specifically, refer to... Figure 3 , 4In 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 60 is installed within the receiving cavity. The outer lid 121 covers the outside of the receiving cavity. The first ends of the second tube 62, the straw 64, and the third tube 63 are also installed within the receiving cavity. The outer lid 121 encapsulates the first ends of the water pump 60, the second tube 62, the straw 64, and the third tube 63 within the receiving cavity. The outer lid 121 is provided with a locking member 1212, and the extraction chamber 50 is provided with a locking hole 514. The cup lid can be locked or opened by engaging the locking member 1212 with the locking hole 514. The top of the outer lid 121 is also provided with a flip-top cover 1211 connected to it. Opening the flip-top cover 1211 exposes the second end of the straw 64, facilitating the user's intake.

[0060] Furthermore, referring to Figure 2 , Figure 3 The mounting cover 122 is positioned over the opening of the extraction chamber 50, and one side of the mounting cover 122 is rotatably connected to the extraction chamber 50. The inner cover 123 is positioned over the opening of the grinding chamber 20, and the inner cover 123 is rotatably connected to the mounting cover 122. That is, the outer cover 121 and the mounting cover 122 as a whole can be flipped relative to the extraction chamber 50, thereby opening or closing the extraction chamber 50 and the grinding chamber 20, facilitating the addition of coffee beans to the grinding chamber 20. A second bearing 124 is provided between the inner cover 123 and the mounting cover 122. Figure 3 , Figure 4 The outer ring of the second bearing 124 is tightly attached to the inner cover 123 and the outer ring of the second bearing 124 is tightly attached to the mounting cover 122. Through the second bearing 124, the grinding chamber 20 and the inner cover 123 can rotate more smoothly in the second direction relative to the mounting cover 122, ensuring that the grinding chamber 20 and the inner cover 123 rotate at high speed during the extraction process, and the extracted coffee liquid overflows from the gap between the grinding chamber 20 and the inner cover 123.

[0061] Optionally, refer to Figure 6 The grinding chamber 20 has an overflow groove 202 at the edge of its opening. The inner cover 123 seals the grinding chamber 20, preventing coffee powder from flying out during grinding. Simultaneously, the overflow groove 202 at the edge of the grinding chamber 20's opening allows the extracted coffee liquid to flow upwards along the overflow groove 202 and out of the grinding chamber 20 during centrifugal extraction. The small aperture of the overflow groove 202 prevents coffee powder from overflowing, further ensuring the flavor of the extracted coffee liquid.

[0062] Reference Figure 8Furthermore, in one embodiment, the inner wall of the first chamber 510 extends upward along the outer wall of the grinding chamber 20 to a first position 5102, and the cover wall of the inner cover 123 extends downward along the outer wall of the grinding chamber to a second position 1232. The height of the first position 5102 is higher than the height of the second position 1232. The portion of the inner wall of the first chamber 510 from the first position 5102 to the second position 1232 is a leak-proof section 5104, and the inner diameter of the leak-proof section 5104 gradually decreases from the first position 5102 to the second position 1232. Because the coffee liquid ejected from the opening of the grinding chamber 20 flows out along its outer wall, and the grinding chamber 20 rotates at high speed during centrifugal extraction, the height of the first position 5102 is set higher than the second position 1232, causing the inner wall of the first chamber 510 to overlap and interlock with the cover wall of the inner cover 123. This completely surrounds the outer wall of the grinding chamber 20. Furthermore, the inner diameter of the leak-proof section 5104 gradually decreases from the first position 5102 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 510, and then into the storage chamber 101, preventing coffee liquid leakage. Further, the cover wall of the mounting cover 122 is provided with a wedge-shaped section 1222 that matches the upper section of the leak-proof section 5104. The wedge-shaped section 1222 cooperates with the leak-proof section 5104 to better seal the opening of the first chamber 510.

[0063] Reference Figure 4 Furthermore, the coffee cup also includes a cooling mechanism 70 and a housing 80. The cooling mechanism 70 is disposed within the housing 80 and located below the cup body 10. The cooling mechanism 70 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 housing 80 is fitted over the cup body 110. Furthermore, a heat-insulating material is provided between the housing 80 and the cup body 110 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 over the pipe to prevent heat exchange between the liquid in the storage chamber 101 and the outside environment as it flows through the pipe. After the coffee liquid extracted by the grinding chamber 20 overflows, it flows into the storage chamber 101. The water pump 60 repeatedly pumps the liquid in the storage chamber 101 into the grinding chamber 20 through the pipe for multiple extractions. After this cycle is repeated many times, the liquid in the storage chamber is cooled down more quickly, and cold brew or iced brew coffee liquid with a better taste can be made in a short time.

[0064] Specifically, in one embodiment, the cooling mechanism 70 includes a cooling element 710, a radiator 720, and a fan. The cooling element 710 is attached to the bottom wall of the cup body 10, and the radiator 720 is located on the side of the cooling element 710 away from the cup body 10. The fan blows air towards the radiator 720. When the cooling element 710 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 720. The fan blows the heat out of the outer casing 80.

[0065] Optionally, in this embodiment, the fan includes a first fan 730 and a second fan 740, with the first fan 730 positioned below the heat sink 720. The heat sink 720 is annular, and the second fan 740 is positioned within the inner ring of the heat sink 720. The outer casing 80 has a first air vent 801 corresponding to the position of the first fan 730 and a second air vent 802 corresponding to the position of the heat sink 720. Specifically, the first fan 730 is an axial fan, and the second fan 740 is a blower. When the first fan 730 and the second fan 740 are activated, outside air enters the outer casing 80 through the first air vent 801, flows to the second fan 740, exchanges heat with the heat sink 720, and is finally blown out through the second air vent 802, carrying the heat out of the outer casing 80.

[0066] Optionally, in other embodiments, the fan includes a first fan 730 or a second fan 740, and the first vent 801 and the second vent 802 are adjusted to be either an air inlet or an air outlet, depending on the heat dissipation effect. That is, heat dissipation is achieved through one of the fans to meet the needs of different products.

[0067] Furthermore, referring to Figure 3 In one embodiment, the cooling mechanism 70 further includes a heat insulation plate 712 and a heat conducting plate 714. The heat insulation plate 712 is located between the heat conducting plate 714 and the bottom wall of the cup body 10. The cup body 10 is a metal cup. One side of the cooling plate 710 is attached 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 712, and the other side of the cooling plate 710 extends into the clearance hole. One side of the heat conducting plate 714 protrudes into the clearance hole and is attached to the cooling plate 710. The other side of the heat conducting plate 714 is attached to the radiator 720. The cold side of the cooling plate 710 is attached 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 712 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 710 contacts the heat-conducting plate 714, transferring heat to the heat-conducting plate 714, and then dissipating it through the heat sink 720.

[0068] Reference Figure 1-4Furthermore, in one embodiment, the coffee cup also includes a handle 81, a control component 90, and a battery 91. The handle 81 is connected to one side of the housing 80, and the control component 90 is disposed within the handle 81. A control switch 92, electrically connected to the control component 90, is provided on the handle 81. The battery 91 is disposed within the housing 80 and located below the cooling mechanism 70. The control component 90 is electrically connected to the battery 91, the drive mechanism 40, the cooling mechanism 70, and the water pump 60. By rationally arranging the control component 90 within the space of the handle 81, the coffee cup can be conveniently and quickly opened or closed by operating the control switch 92. (Refer to...) Figure 2 The top of the cup handle 81 is provided with a first contact 93, and the corresponding position of the extraction chamber 50 is provided with a second contact that matches the first contact 93. When the cup lid 120 and the extraction chamber 50 are removed, the first contact 93 and the second contact are disconnected, and the water pump 60 is automatically powered off. When the cup lid 120 and the extraction chamber 50 are installed on the cup body 110, the first contact 93 and the second contact are connected, and the water pump 60 can be powered on and started.

[0069] Furthermore, a temperature sensor is installed at the first end of the first tube, and the temperature sensor is electrically connected to the control component 90. The temperature sensor detects the outlet water temperature of the liquid storage chamber, and the control component 90 controls the cooling element according to the outlet water temperature, thereby timely detecting and adjusting the water temperature.

[0070] Reference Figure 1-4 This application also provides a coffee-making method using the coffee cup described in any of the above embodiments, the method comprising the following steps:

[0071] S100: Obtain the start command. The coffee cup can be turned on by operating the control switch 92, enabling the control component 90 to obtain the start command. In this embodiment, the coffee cup is turned on or off by a single control switch 92, making one-button operation simpler and more convenient.

[0072] S200: According to the start command, the drive mechanism 40 is controlled to drive the clutch mechanism 30 and the cutter 21 to rotate relative to the grinding chamber 20 in the first direction, grinding the coffee beans in the grinding chamber 20 for time T1. The control component 90 controls the drive mechanism 40 to rotate forward, the cutter 21 rotates at high speed, the grinding chamber 20 enters the grinding state, and the drive mechanism 40 automatically stops after time T1 is reached. The coarseness of the coffee powder can be adjusted by controlling the time T1.

[0073] S300: After grinding, the control drive mechanism 40 drives the clutch mechanism 30, the cutter 21, and the grinding chamber 20 to rotate in the second direction. Simultaneously, water is sprayed into the grinding chamber 20 to extract the coffee powder within it for time T2. The control component 90 controls the drive mechanism 40 to reverse, causing the cutter 21 and the grinding chamber 20 to rotate synchronously at high speed, and the grinding chamber 20 enters the extraction state. Simultaneously, the control component 90 controls the water pump 60 to start, drawing liquid from the storage chamber 101 into the grinding chamber 20, mixing the water and coffee powder to achieve centrifugal extraction. After time T2 is reached, the drive mechanism 40 automatically stops. The concentration of the extracted coffee liquid can be adjusted by controlling the T2 time. The concentration of the coffee liquid can also be adjusted by varying the amount of coffee powder and the amount of water in the storage chamber 101.

[0074] Furthermore, the coffee-making method further includes the following steps:

[0075] S400: The cooling mechanism 70 is activated to cool the liquid in the storage chamber 101. The control component 90 controls the activation of the cooling mechanism 70 to exchange heat with the liquid in the storage chamber 101, lowering its temperature. This allows for low-temperature water extraction of coffee, resulting in a cold brew or iced brew with a better flavor. The taste of the coffee is adjusted by regulating the temperature of the liquid in the storage chamber 101. The temperature of the cup body 110, the cooling mechanism 70, or the pipes is detected by a temperature sensor, and the control component 90 adjusts the temperature of the cooling mechanism 70 based on the detection results.

[0076] Furthermore, in one embodiment, the coffee-making method further includes the following steps:

[0077] S500: Start the water pump 60 to introduce the liquid in the storage chamber 101 into the grinding chamber 20 through the pipe to extract coffee. After multiple cycles, cold brew coffee liquid is obtained. The liquid in the storage chamber 101 is pumped into the grinding chamber 20 by the water pump 60 and mixed with the centrifugal coffee powder. This process is repeated multiple times, which not only cools the liquid in the storage chamber 101 faster, but also makes the final extracted coffee liquid taste better.

[0078] The coffee cup and coffee making method described in the above embodiments combine grinding and extraction functions in the coffee cup. It utilizes centrifugal force to extract coffee, resulting in a high extraction rate and superior coffee flavor. Furthermore, the nested arrangement of the cup body 10 and the grinding chamber 20, with the grinding 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 grinding chamber 20 rotates at high speed. The centrifugal motion during extraction mixes the coffee liquid with air, creating a layer of oily foam on the surface of the coffee liquid, similar to a fluffy cake, further enhancing the flavor of the coffee.
