Description

Technical Field

[0001] The present invention relates to the technical field of coffee equipment, and particularly relates to a coffee cup and a coffee making method. Background Art

[0002] Coffee is a widely popular beverage. Coffee lovers like to make coffee by freshly grinding coffee beans in order to obtain more mellow coffee. There are many coffee machines on the market that can grind and extract coffee beans, but generally, coffee machines are relatively large in size and are suitable for being placed at home or in a fixed place for use. They are not convenient to carry and are inconvenient to use. Although coffee cups are smaller in size than coffee machines, ordinary coffee cups can only brew coffee powder and do not have a grinding function; while coffee cups with both grinding and brewing functions are rare. Generally, they are directly brewed through a boiling water filter screen, with a low coffee extraction rate and poor taste. If brewed with low-temperature water, the extraction rate is even lower and the extraction speed is slower. Summary of the Invention

Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0044] The following will describe in detail the specific implementation manners of the present disclosure in conjunction with the accompanying drawings.

[0045] Referring to Figure 1-4 , an embodiment of the present invention provides a coffee cup, which includes a cup body 10, a grinding chamber 20, a clutch mechanism 30, and a driving 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 driving mechanism 40 is connected to the clutch mechanism 30. A cutter 21 is provided inside the grinding chamber 20, and the cutter 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 driving mechanism 40 drives the cutter 21 to rotate in a first direction. In the extraction state, the clutch mechanism 30 is connected to the grinding chamber 20, and the driving mechanism 40 drives the cutter 21 and the grinding chamber 20 to rotate in a second direction. Specifically, the cup body 10 includes an openable and closable cup body 110 and a cup cover 120, and the cup cover 120 covers the opening of the grinding chamber 20. The driving mechanism 30 can be a motor.

[0046] During use, referring 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 cavity 101 of the cup body 10, open the cup cover 120, and put coffee beans into the grinding chamber 20; then cover the cup cover 120, install the grinding chamber 20 into the cup body 110 of the cup body 10, referring to Figure 1; Then, start the driving mechanism 40 to drive 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 a high speed to crush the coffee beans in the grinding chamber 20. After the crushing is completed, the driving mechanism 40 reverses to drive the clutch mechanism 30, the cutter 21, and the grinding chamber 20 to rotate in the second direction. The coffee powder is thrown towards the side wall of the grinding chamber 20 under the action of centrifugal force. At the same time, the water in the liquid storage cavity 101 is introduced into the grinding chamber 20 to collide and mix with the coffee powder rotating at a high speed. The extracted coffee liquid then overflows from the opening of the grinding chamber 20 and flows into the liquid storage cavity 101. The liquid in the liquid storage cavity 101 can be cyclically introduced into the grinding chamber 20 to extract coffee, and finally, coffee liquid with sufficient extraction is obtained. Through the flexible cooperation of the clutch mechanism 30 with the grinding chamber 20 and the cutter 21, the coffee cup has both grinding and extraction functions. Moreover, by extracting coffee through centrifugal force, the extraction rate is high, and the coffee taste is better. In addition, the cup body 10 and the grinding chamber 20 are nested, and the grinding chamber 20 serves as a chamber for both grinding and extraction, effectively saving space. The overall volume of the coffee cup is smaller and more convenient to carry, and it is easy to use.

[0047] Referring to Figures 4-6 , in one embodiment, the clutch mechanism 30 includes a base 310 and a first engaging member 320. The first end of the base 310 is connected to the cutter 21, and the 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 is separated from the second engaging member 330, that is, the base 310, the first engaging member 320, and the cutter 21 rotate in the first direction along with the driving mechanism 40, while the second engaging member 330 and the grinding chamber 20 remain stationary. In the extraction state, the first engaging member 320 is engaged with the second engaging member 330, that is, 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 the second direction along with the driving mechanism 40. Through the flexible cooperation of the first engaging member 320 and the second engaging member 330, when the driving mechanism 40 rotates in different directions, the grinding chamber 20 is in different functional states, and two functional requirements are realized in the same chamber.

[0048] Referring to Figure 6 , optionally, the cutter 21 includes a screw and two blades arranged in a cross-laminated manner. A connection hole is provided in the middle of the blade, and the screw passes through the connection hole to lock the blade on the base 310. One of the blades is bent downward, and the other blade is bent upward. On the one hand, it increases the probability of the blade colliding with the coffee beans and improves the crushing efficiency. On the other hand, it prevents the coffee beans from getting stuck between the blade and the bottom wall of the grinding chamber 20.

[0049] Referring to Figure 6, specifically, in one embodiment, the base 310 includes an upper cover 311, a bottom plate 312 and a boss 313, and one side of the bottom plate 312 is connected to the boss 313. In this embodiment, the bottom plate 312 and the boss 313 are of an integral structure. A first bearing 340 is sleeved on the boss 313. The first engaging member 320 is rotatably connected to the bottom plate 312. A mounting platform 201 protrudes inward from the middle of the bottom wall of the grinding chamber 20, and a mounting hole is provided in the mounting platform 201. The upper cover 311 covers the mounting platform 201 and is connected to the cutter 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 abuts against the boss 313, and the outer ring of the first bearing 340 abuts against the mounting platform 201. During grinding, the boss 313, the upper cover 311 and the cutter 21 can rotate more smoothly relative to the grinding chamber 20 in the first direction, ensuring that the cutter 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 and extends into the mounting hole and is integrally connected to the boss 313; an installation space is formed in the area below the mounting platform 201. The bottom plate 312 is located below the bottom wall of the grinding chamber 20. The upper cover 311 and the bottom plate 312 enclose the boss 313, the first bearing 340 and the first engaging member 320 in the installation space. The whole clutch mechanism 30 is limited in the grinding chamber 20, and the degree of freedom in the axial direction is restricted. By providing the first bearing 340, the whole clutch mechanism 30 can rotate around the mounting platform 201 in the first direction.

[0050] Specifically, refer to Figure 4 , Figure 6 , the first engaging member 320 is a tooth block. A rotating hole is provided at one end of the tooth block, and the other end is in a pointed tooth shape. A convex column is provided on the bottom plate 312, and the tooth block is rotatably mounted on the convex column through the rotating hole. A rotating gap is left between the convex column and the boss 313. When the driving mechanism 40 drives the base 310 and the first engaging member 320 to rotate in the first direction, the tip of the first engaging member 320 can rotate around the convex column within the range of the rotating gap, and the tip of the first engaging member 320 does not get stuck on the second engaging member 330, and the two remain separated, so that the grinding chamber 20 does not rotate therewith. The second engaging member 330 is a toothed ring with a plurality of internal teeth, and the internal teeth face the same direction. The toothed ring is fixed on the hole wall of the mounting hole and is located at the position corresponding to the first engaging member 320. The tooth block can be meshed and clamped with the internal teeth when rotating in the second direction. Optionally, a spring is further abutted 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 be engaged with the second engaging member 330 when rotating in the second direction.

[0051] Refer to Figure 2 , Figure 4, Figure 7 and Figure 8 , in one embodiment, the coffee cup further includes an extraction chamber 50, the extraction chamber 50 is sleeved on the outer periphery of the grinding chamber 20, the driving mechanism 40 is installed in the extraction chamber 50, and the extraction chamber 50 is detachably installed in the cup body 10. The cup lid 120 is openably and closably covered on the opening above the grinding chamber 20 and the extraction chamber 50, and the extraction chamber 50 is detachably installed in the cup body 110. By arranging the extraction chamber 50 to be sleeved on the outer periphery of the grinding chamber 20, the driving mechanism 40 can be connected to the clutch mechanism 30 on the grinding chamber 20. Refer to Figure 2 , when it is necessary to fill water or pour out the coffee liquid, the extraction chamber 50 and the driving mechanism 40, the grinding chamber, the clutch mechanism 30 and the cup lid 120 inside it are taken off from the cup body 110 as a whole, the liquid storage cavity 101 is exposed, and then water is injected into the liquid storage cavity 101 or the coffee liquid in the liquid storage cavity 101 is poured out.

[0052] Refer to Figure 7 , Figure 8 , the extraction chamber 50 includes a first chamber 510 and a second chamber 520 which are connected up and down. The first chamber 510 is sleeved on the outer periphery of the grinding chamber 20, an extraction gap is left between the inner wall of the first chamber 510 and the outer wall of the grinding chamber 20, a through hole 511 is formed in the bottom wall of the first chamber 510, and the through hole 511 is communicated with the liquid storage cavity 101. By arranging the first chamber 51 on the outer periphery of the grinding chamber 20, after the coffee liquid extracted by the grinding chamber 20 overflows from its opening, it flows into the first chamber 510 along the extraction gap, and then flows into the liquid storage cavity 101 through the through hole 511, while preventing the coffee liquid overflowed by the high-speed rotating grinding chamber 20 from being thrown outwards and avoiding coffee liquid leakage. The second chamber 520 is located below the grinding chamber 20, that is, corresponding to the position where the clutch mechanism 30 is located, and the driving mechanism 40 is arranged in the second chamber 520, which is convenient for the driving mechanism 40 to be in transmission connection with the clutch mechanism 30. Further, an installation plate is arranged at the opening of the second chamber 520 to encapsulate the driving mechanism 40 in the second chamber 520, and the driving shaft of the driving mechanism 40 extends out of the installation plate and is connected to the clutch mechanism 30. Optionally, a heat insulation member 540 is further arranged above the installation plate to prevent the heat of the driving mechanism 40 from being conducted into the grinding chamber 20 and affecting the taste of the coffee liquid.

[0053] Refer to Figure 7, in one embodiment, a surrounding retaining wall 512 protruding into the first chamber 510 is provided at the opening of the second chamber 520. The bottom wall of the first chamber 510 is inclined, and the bottom wall of the first chamber 510 and the retaining wall 512 form a flow channel 513. The through hole 511 is provided at the lowest point of the flow channel 513. The mounting plate is pressed against the retaining wall 512, and the retaining wall 512 and the mounting plate prevent the coffee liquid from leaking into the second chamber 520 and affecting the use of the driving mechanism. Through the inclined flow channel 513, the coffee liquid smoothly flows along the inclined direction of the flow channel 513 to the through hole 511, and then all enters the liquid storage cavity 101. Refer to Figure 8 , optionally, a filter screen 530 can also be provided 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] Refer to Figures 4-6 and Figure 8 , in one embodiment, an elastic member 41 is provided between the top of the driving mechanism 40 and the clutch mechanism 30. Further, a transmission member 42 is connected to the output shaft of the driving mechanism 40. A limiting hole 3102 is provided in the base. The transmission member 42 is disposed in the limiting hole 3102, and the elastic member 41 abuts between the top end of the transmission member 42 and the base 310. Specifically, the transmission member 42 is a polygonal member, and the limiting hole 3102 is a polygonal hole. The transmission member 42 and the limiting hole 3102 cooperate to drive the base 310 to rotate. In other embodiments, the elastic member 41 can also be provided between the bottom of the driving mechanism 40 and the second chamber 520. Through the elastic space of the elastic member 41, it is avoided that the installation of the driving mechanism 40 and the clutch mechanism 30 is blocked due to errors during the assembly process, and it is ensured that the driving mechanism 40 can be better connected to the clutch mechanism 30.

[0055] Further, refer to Figure 3 and Figure 4, in one embodiment, the coffee cup further includes a water pump 60 and a pipeline. One end of the pipeline is communicated with the liquid storage cavity 101, and the other end extends into the grinding bin 20. The water pump 60 is communicated with the pipeline. The water in the liquid storage cavity 101 is pumped into the grinding bin 20 by the water pump 60 for coffee extraction. The water pump 60 can be a peristaltic pump, which is small in size and more hygienic. The pipeline includes a first pipe 61, a second pipe 62, and a third pipe 63 that are connected in sequence. The first end of the first pipe 61 extends into the liquid storage cavity 101, and the second end is a plug-in end 82. The first end of the second pipe 62 can be quickly plugged and communicated with the second end of the first pipe 61, and the second end of the second pipe 62 is connected to the water inlet of the water pump 60. The first end of the third pipe 63 is connected to the water outlet of the water pump 60, and the second end passes through the cup lid 120 and is inserted into the grinding bin 20. The second end of the third pipe 63 is provided with a water spraying hole. When the water pump 60 is started, the liquid in the liquid storage cavity 101 flows into the second pipe 62 from the first pipe 61, then passes through the third pipe 63, and finally is sprayed into the grinding bin 20 through the water spraying hole and mixed with the coffee powder in the grinding bin 20. The aperture of the water spraying hole is less than 1 mm, such as 0.4 mm, 0.5 mm, 0.6 mm, etc. In this way, the spraying pressure is greater, so that the sprayed liquid can be better mixed with the coffee powder, and then the coffee liquid is extracted under the action of centrifugal force and is thrown out from the opening of the grinding bin 20, improving the coffee extraction rate and extraction speed. In this embodiment, the third pipe 63 is arranged above the middle of the cutter 21 to avoid the rotation path of the cutter 21 and prevent interference between the two. In other embodiments, the third pipe 63 can also be arranged at a position close to the lower part of the inner wall of the grinding bin 20, so that the sprayed water can be better mixed with the coffee powder centrifugally thrown towards the inner wall.

[0056] Further, the pipeline further includes a straw 64, and the first end of the straw 64 is communicated with the second pipe 62. After the extraction is completed, the coffee liquid in the liquid storage cavity 101 can be directly sucked out through the straw 64 for easy drinking.

[0057] The second pipe 62, the third pipe 63, and the straw 64 are all arranged on the cup lid 120. When adding water or pouring out the coffee liquid, the second pipe 62 can be quickly disassembled and plugged or separated from the first pipe 61.

[0058] Further, the cup body 10 further includes a cup handle 81 connected to one side of the cup body 110, and the first pipe 61 extends along the cup handle 81 from bottom to top. Optionally, the water pump 60 is arranged in the cup handle 81. Through the space in the cup handle 81, the water pump 60 and the pipeline are reasonably arranged.

[0059] In other embodiments, the water pump 60 is arranged in the cup lid 120 to ensure that after the cup lid 120 is removed from the cup body 110, the water pump 60 and the first pipe 61 are in a disconnected state, avoiding water spraying out from the second end of the first pipe 61 and causing splashing. Specifically, refer to Figure 3 , 4, 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, the water pump 60 is installed in the receiving cavity, and the outer lid 121 covers outside the receiving cavity. The first ends of the second pipe 62, the straw 64 and the third pipe 63 are also installed in the receiving cavity. The water pump 60, the first ends of the second pipe 62, the straw 64 and the third pipe 63 are encapsulated in the receiving cavity by the outer lid 121. A locking member 1212 is provided on the outer lid 121, and a locking hole 514 is provided on the extraction chamber 50. The cup lid can be locked or opened by the cooperation of the locking member 1212 and the locking hole 514. A flip lid 1211 is also provided at the top of the outer lid 121 and is rotatably connected thereto. By opening the flip lid 1211, the second end of the straw 64 can be exposed, facilitating the user to suck.

[0060] Further, referring to Figure 2 , Figure 3 , the mounting lid 122 covers the opening of the extraction chamber 50 and one side of the mounting lid 122 is rotatably connected to the extraction chamber 50. The inner lid 123 covers the opening of the grinding chamber 20, and the inner lid 123 is rotatably connected to the mounting lid 122. That is, the outer lid 121 and the mounting lid 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 into the grinding chamber 20. A second bearing 124 is provided between the inner lid 123 and the mounting lid 122. Combining Figure 3 , Figure 4 , the outer ring of the second bearing 124 is closely attached to the inner lid 123, and the outer ring of the second bearing 124 is closely attached to the mounting lid 122. Through the second bearing 124, the grinding chamber 20 and the inner lid 123 can rotate more smoothly relative to the mounting lid 122 in the second direction, ensuring that the grinding chamber 20 and the inner lid 123 rotate at a high speed during the extraction process, and the extracted coffee liquid overflows from the gap between the grinding chamber 20 and the inner lid 123.

[0061] Optionally, referring to Figure 6 , an overflow groove 202 is provided at the edge of the opening of the grinding chamber 20. The grinding chamber 20 is closed by the inner lid 123 to prevent coffee powder from flying out of the grinding chamber 20 during the grinding process. At the same time, by providing the overflow groove 202 at the edge of the opening of the grinding chamber 20, during the centrifugal extraction process, the extracted coffee liquid flows out of the grinding chamber 20 upward along the overflow groove 202. The aperture of the overflow groove 202 is relatively small, and it is difficult for coffee powder to overflow, further ensuring the taste of the extracted coffee liquid.

[0062] Referring to Figure 8, Further, in one embodiment, the inner wall of the first bin 510 extends upward along the outer wall of the grinding bin 20 to the first position 5102, the cover wall of the inner cover 123 extends downward along the outer wall of the grinding bin to the second position 1232, and the height of the first position 5102 is higher than the height of the second position 1232. The part of the inner wall of the first bin 510 from the first position 5102 to the second position 1232 is the 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. Since the coffee liquid thrown out at the opening of the grinding bin 20 flows out along its outer wall, and the grinding bin 20 rotates at a high speed during the centrifugal extraction process, the height of the first position 5102 is set higher than the second position 1232, so that the inner wall of the first bin 510 and the cover wall of the inner cover 123 overlap and cross each other. In this way, the outer wall of the grinding bin 20 is completely surrounded, and the inner diameter of the leak-proof section 5104 gradually decreases from the first position 5102 to the second position 1232, showing a flared shape, so that the extracted coffee liquid can only flow along the extraction gap to the bottom wall of the first bin 510, and then flow into the liquid storage cavity 101, avoiding coffee liquid leakage. Further, the cover wall of the mounting cover 122 is provided with a wedge-shaped section 1222 matching the upper section of the leak-proof section 5104. By matching the wedge-shaped section 1222 with the leak-proof section 5104, the opening of the first bin 510 is better sealed.

[0063] Refer to Figure 4 , Further, the coffee cup further includes a refrigeration mechanism 70 and a housing 80. The refrigeration mechanism 70 is disposed in the housing 80 and located below the cup body 10. The refrigeration mechanism 70 cools to exchange heat with the heat in the cup body 10 to reduce the temperature of the liquid in the liquid storage cavity 101, so as to extract low-temperature coffee liquid, better retain the rich taste of coffee, and meet the needs of people who like iced coffee. The housing 80 is sleeved outside the cup body 110. Further, a heat insulation material is provided between the housing 80 and the cup body 110 to prevent the liquid in the liquid storage cavity 101 from exchanging heat with the outside world and affecting the taste of coffee. The pipe is also sleeved with a heat insulation material to prevent the liquid in the liquid storage cavity 101 from exchanging heat with the outside world when flowing through the pipe. The coffee liquid extracted by the grinding bin 20 overflows and flows into the liquid storage cavity 101. The water pump 60 repeatedly pumps the liquid in the liquid storage cavity 101 into the grinding bin 20 through the pipe for multiple extractions. After repeating this cycle multiple times, the liquid in the liquid storage cavity can be cooled faster, and cold brew or iced brew coffee liquid with better taste can be made in a short time.

[0064] Specifically, in one embodiment, the refrigeration mechanism 70 includes a refrigeration fin 710, a radiator 720, and a fan. The refrigeration fin 710 is closely attached to the bottom wall of the cup body 10, and the radiator 720 is located on the side of the refrigeration fin 710 away from the cup body 10. The fan blows air toward the radiator 720. When the refrigeration fin 710 is started, one side of the refrigeration fin 710 is a cold side, and the other side is a hot side. The cold side exchanges heat with the cup body 10, and the heat on the hot side is dissipated outward by the radiator 720, and the fan blows the heat out of the housing 80.

[0065] Optionally, in this embodiment, the fan includes a first fan 730 and a second fan 740, and the first fan 730 is arranged below the radiator 720. The radiator 720 is in a ring shape, and the second fan 740 is arranged in the inner circle of the radiator 720. The housing 80 is provided with a first air hole 801 at a position corresponding to the first fan 730, and the housing 80 is provided with a second air hole 802 at a position corresponding to the radiator 720. Specifically, the first fan 730 is an axial flow fan, and the second fan 740 is a blower. When the first fan 730 and the second fan 740 are started, the outside air enters the housing 80 through the first air hole 801, flows to the second fan 740, and then exchanges heat with the radiator 720, and finally blows out through the second air hole 802 to take the heat out of the housing 80.

[0066] Optionally, in other embodiments, the fan includes the first fan 730 or the second fan 740, and one of the first air hole 801 and the second air hole 802 is adjusted to be an air inlet and the other to be an air outlet according to the heat dissipation effect, that is, heat dissipation through one of the fans can meet the use needs of different products.

[0067] Further, refer to Figure 3 In one embodiment, the refrigeration mechanism 70 further includes a heat insulating plate 712 and a heat conducting plate 714, wherein the heat insulating 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 refrigeration plate 710 is closely 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 insulating plate 712, and the other side of the refrigeration plate 710 extends into the clearance hole. The middle part of one side of the heat conducting plate 714 protrudes into the clearance hole and is closely attached to the refrigeration plate 710, and the other side of the heat conducting plate 714 is closely attached to the radiator 720. The cold side of the refrigeration plate 710 is closely attached to the bottom wall of the metal cup, and heat is exchanged with the cup body 10 to reduce the temperature of the liquid in the cup. The heat insulating plate 712 is placed outside the bottom wall of the metal cup to better maintain the temperature in the cup. The hot side of the cooling fin 710 contacts the heat conducting plate 714 , and conducts the heat to the heat conducting plate 714 , which is then dissipated by the heat sink 720 .

[0068] Reference Figure 1-4, Further, in one embodiment, the coffee cup further 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 inside 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 inside the housing 80 and below the refrigeration mechanism 70, and the control component 90 is electrically connected to the battery 91, the drive mechanism 40, the refrigeration mechanism 70, and the water pump 60. By reasonably arranging the control component 90 in the space of the handle 81, the coffee cup can be conveniently and quickly turned on or off by operating the control switch 92. Refer to Figure 2 , a first contact 93 is provided at the top of the handle 81, and a second contact matching the first contact 93 is provided at a corresponding position of the extraction chamber 50. 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 conducted, and the water pump 60 can be powered on and started.

[0069] Further, a temperature sensor is provided at the first end of the first pipe, and the temperature sensor is electrically connected to the control component 90. By detecting the outlet water temperature of the liquid storage chamber through the temperature sensor, the control component 90 controls the refrigeration sheet according to the outlet water temperature, so as to detect and adjust the water temperature in time.

[0070] Refer to Figure 1-4 , Another embodiment of the present application provides a coffee making method, using the coffee cup described in any of the above embodiments. The method includes the following steps:

[0071] S100: Obtain a start instruction. The coffee cup can be turned on by operating the control switch 92, so that the control component 90 obtains the start instruction. In this embodiment, it is turned on or off through a control switch 92, and the one-key operation is simpler and more convenient.

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

[0073] S300: After the grinding is completed, control the driving mechanism 40 to drive the clutch mechanism 30, the cutter 21 and the grinding chamber 20 to rotate in the second direction, and at the same time spray water into the grinding chamber 20 to extract the coffee powder in the grinding chamber 20 for a time period of T2. The control component 90 controls the driving mechanism 40 to reverse, and the cutter 21 and the grinding chamber 20 rotate synchronously at high speed, and the grinding chamber 20 enters the extraction state; at the same time, the control component 90 controls the water pump 60 to start, and pumps the liquid in the liquid storage cavity 101 into the grinding chamber 20. The water and the coffee powder are mixed to achieve coffee centrifugal extraction; after reaching the time period of T2, the driving mechanism 40 automatically stops. The concentration of the extracted coffee liquid can be adjusted by controlling the time period of T2. The concentration of the coffee liquid can also be adjusted by varying the amount of coffee powder and the amount of water in the liquid storage cavity 101.

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

[0075] S400: Start the refrigeration mechanism 70 to cool the liquid in the liquid storage cavity 101. The control component 90 controls the refrigeration mechanism 70 to start, exchange heat with the liquid in the liquid storage cavity 101, reduce its temperature, and extract coffee with low-temperature water to obtain cold-brewed or iced-brewed coffee with a better taste. By adjusting the temperature of the liquid in the liquid storage cavity 101, the taste of the coffee liquid is adjusted. The temperature of the cup body 110 or the refrigeration mechanism 70 or the pipeline is detected by a temperature sensor, and the control component 90 adjusts the temperature of the refrigeration mechanism 70 according to the detection result.

[0076] Further, 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 liquid storage cavity 101 into the grinding chamber 20 through a pipeline to extract coffee, and cold-brewed coffee liquid is obtained after multiple cycles. The liquid in the liquid storage cavity 101 is pumped into the grinding chamber 20 by the water pump 60 and mixed with the coffee powder driven by centrifugation. After repeated cycles many times, not only the liquid in the liquid storage cavity 101 is cooled faster, but also the taste of the finally extracted coffee liquid is better.

[0078] For the coffee cup and the coffee making method of the above embodiments, the coffee cup has both grinding and extraction functions, and extracts coffee by centrifugal force, with a high extraction rate and a better coffee taste. Moreover, the cup body 10 and the grinding chamber 20 are nested, and the grinding chamber 20 has a chamber for both grinding and extraction, effectively saving space. The overall volume of the coffee cup is smaller and more convenient to carry, and it is easy to use. During the coffee liquid extraction process, the grinding chamber 20 rotates at high speed. During the extraction centrifugal movement, the coffee liquid is mixed with air, and an oil foam similar to a fluffy cake will be generated on the surface of the coffee liquid, further enhancing the taste of the coffee liquid.
