[0024] 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.

[0025] The specific embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0026] Reference Figure 1-4 This utility model provides a cold brew coffee cup, including a lid 120, a cup body 10, an inner chamber 20, a drive mechanism 40, and a cooling mechanism 70. The drive mechanism 40 is kinetically connected to the inner chamber 20. The inner chamber 20 is disposed inside the cup body 10. The lid 120 covers the opening of the inner chamber 20. A liquid storage cavity 101 is formed inside the cup body 10, and the liquid storage cavity 101 communicates with the inner chamber 20. The cooling mechanism 70 is attached to the liquid storage cavity 101. The drive mechanism 40 can be a motor.

[0027] In use, water is poured into the storage chamber 101, and the cooling mechanism 70 is activated to cool the water in the storage chamber 101. Coffee powder is placed into the inner chamber 20, which is then installed into the cup body 10. The drive mechanism 40 is then activated to rotate the inner chamber 20 at high speed. Under centrifugal force, the coffee powder is thrown against the side wall of the inner chamber 20. Simultaneously, the low-temperature water in the storage chamber 101 is introduced into the inner chamber 20 to collide and mix with the rapidly rotating coffee powder. The extracted coffee liquid overflows from the opening of the inner chamber 20 and flows back into the storage chamber 101. The liquid in the storage chamber 101 can be circulated back into the inner chamber 20 for repeated extraction of coffee, ultimately yielding cold brew coffee. The cooling mechanism 70 directly cools the water in the cup to obtain low-temperature water, eliminating the need for external sources of low-temperature water and environment, making it more convenient to use. Furthermore, the introduction of low-temperature water into the inner chamber 20 allows for thorough contact and extraction of coffee powder and water under centrifugal force, resulting in higher extraction efficiency.

[0028] Specifically, refer to Figure 3 , 4 In one embodiment, the cooling mechanism 70 includes a cooling element 710 and a heat dissipation assembly 720. The cooling element 710 is attached to the bottom wall of the cup body 10, and the heat dissipation assembly 720 is located on the side of the cooling element 710 away from the cup body 10. 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 heat dissipation assembly 720.

[0029] Furthermore, referring to Figure 3 , 4 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 7122. One side of the heat conducting plate 714 protrudes into the clearance hole 7122 and is attached to the cooling plate 710. The other side of the heat conducting plate 714 is attached to the heat dissipation assembly 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 reduce the temperature of the liquid inside the cup. The heat insulation plate 712 is isolated from the bottom wall of the metal cup, better maintaining 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 dissipation component 20.

[0030] Reference Figure 3In this embodiment, the cold brew coffee cup also includes a shell 80, which is fitted over the cup body 10. The drive mechanism 40 and the cooling mechanism 70 are disposed inside the shell 80. The heat dissipation assembly 720 includes a radiator 722, a first fan 724, and a second fan 726. The first fan 724 is disposed below the radiator 722, which is annular. The second fan 726 is disposed within the inner ring of the radiator 722. The shell 80 has a first air vent 801 corresponding to the position of the first fan 724, and a second air vent 802 corresponding to the position of the radiator. Specifically, the first fan 724 is an axial fan, and the second fan 726 is a blower. When the first fan 724 and the second fan 726 are activated, outside air enters the shell 80 through the first air vent 801, flows to the second fan 726, exchanges heat with the radiator 722, and finally is blown out through the second air vent 802, carrying the heat out of the shell 80.

[0031] Optionally, in other embodiments, the heat dissipation assembly 720 includes a heat sink 722, a first fan 724, or a second fan 726. Depending on the heat dissipation effect, one of the first vent 801 and the second vent 802 can be configured as an air inlet and the other as an air outlet. That is, heat dissipation is achieved through one of the fans to meet the needs of different products.

[0032] The heat sink 722 is annular, and the second fan 726 is disposed within the inner ring of the heat sink 722. On the one hand, this arrangement saves space and reduces the volume of the cold brew coffee cup; on the other hand, the second fan 726 in the inner ring blows air outward, better dissipating heat.

[0033] Furthermore, referring to Figure 3 , 4 In one embodiment, the cold brew coffee cup further 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 inner chamber 20. The water pump 60 is connected to the pipe. The water pump 60 draws liquid from the liquid storage chamber 101 into the inner chamber 20 for coffee extraction. By controlling the running time of the water pump 60, the liquid in the liquid storage chamber 101 is repeatedly drawn into the inner chamber 20 to mix with the coffee powder, undergoing multiple extractions to ultimately obtain fully extracted coffee. The water pump 60 can be a peristaltic pump, which is compact and more hygienic.

[0034] Furthermore, an insulation layer 110 is provided between the outer shell 80 and the cup body 10 to prevent the liquid in the liquid storage chamber 101 from exchanging heat with the outside and to ensure that the liquid is kept at a low temperature.

[0035] The pipes are also fitted with heat-insulating material to prevent heat exchange between the liquid in the storage chamber 101 and the outside environment as it flows through the pipes. After the coffee liquid extracted in the inner 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 inner chamber 20 through the pipes for multiple extractions. After this cycle is repeated many times, the liquid in the storage chamber 101 is cooled down more quickly, allowing for the production of cold brew or iced coffee liquid with a better taste in a short time.

[0036] Optionally, refer to Figure 3 , 4 In one embodiment, the pipeline 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 of the first pipe 61 is a plug-in end 82. The first end of the second pipe 62 is plugged into and connected to 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 of the third pipe 63 passes through the cup lid 120 and is inserted into the inner chamber 20. The second end of the third pipe 63 is provided with a spray hole. When the water pump 60 is started, the liquid in the liquid 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 inner chamber 20 through the spray hole, mixing with the coffee powder in the inner chamber 20. The nozzle diameter is less than 1mm, such as 0.4mm, 0.5mm, or 0.6mm, allowing for greater spray pressure. This enables the sprayed liquid to mix better with the coffee grounds, and then, under centrifugal force, extracts the coffee liquid, which is then ejected from the opening of the inner chamber 20, improving the coffee extraction rate and speed. The third tube 63 can be positioned near the lower part of the inner wall of the inner chamber 20, so that the sprayed water directly hits the coffee grounds that have been centrifugally thrown against the inner wall, mixing them to extract iced or cold brew coffee.

[0037] Furthermore, referring to Figure 3 , 4 In one embodiment, the cold brew coffee cup further includes an extraction chamber 50, which is detachably installed within the cup body 10. 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 inner chamber 20, with an extraction gap between the inner wall of the first chamber 510 and the outer wall of the inner chamber 20. A through hole (not shown) is formed on the bottom wall of the first chamber 510, communicating with the liquid storage chamber 101. The second chamber 520 is located below the inner chamber 20, and the drive mechanism 40 is disposed within the second chamber 520. The inner diameter of the first chamber 510 is larger than the inner diameter of the second chamber 520. By fitting the extraction chamber 50 around the outer periphery of the inner chamber 20, the drive mechanism 40 is easily connected to the inner chamber 20 for transmission. (Refer to...) Figure 2When water needs to be added or coffee liquid needs to be poured out, the extraction chamber 50, along with its internal drive mechanism 40, inner chamber 20, and lid 120, are removed from the cup body 10, exposing the liquid storage chamber 101. Water can then be added to the liquid storage chamber 101 or the coffee liquid in the liquid storage chamber 101 can be poured out. The coffee liquid extracted from the inner 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. Further, an installation plate is provided at the opening of the second chamber 520, which encapsulates the drive mechanism 40 within the second chamber 520. The drive shaft of the drive mechanism 40 extends out of the installation plate and is connected to the inner chamber 20 for transmission. Optionally, a heat insulation component 41 is also provided above the installation plate to prevent the heat from the drive mechanism 40 from being conducted into the inner chamber 20, thus affecting the temperature of the coffee liquid. Optionally, a filter screen can also be installed in the first chamber 510 of the extraction chamber 50 to further filter the extracted coffee liquid and improve its taste.

[0038] Optionally, refer to Figure 3 In one embodiment, the cup lid 120 includes an outer lid 121, a mounting lid 122, and an inner lid 123 sequentially fitted together. 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 water pump 60 is positioned inside the cup lid 120 to ensure that after the cup lid 120 is removed from the cup body 10, 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 splashing. The mounting lid 122 covers the opening of the extraction chamber 50, and the inner lid 123 covers the opening of the inner chamber 20. The first ends of the second pipe 62 and the third pipe 63 are also installed within the receiving cavity. The water pump 60, the first end of the second pipe 62 and the third pipe 63 are sealed in the receiving cavity by the outer cover 121. The outer cover 121 is provided with a locking member 1212 and the extraction chamber 50 is provided with a locking hole. The cup lid 120 is locked on the extraction chamber 50 by the locking member 1212, so that the internal space of the inner chamber 20 and the extraction chamber 50 is sealed to prevent coffee from overflowing.

[0039] Reference Figure 3 Furthermore, the pipeline also includes a straw 64, the first end of which is connected to the second tube 62. After extraction, the coffee liquid in the reservoir 101 can be directly drawn out through the straw 64 for easy drinking. The straw 64 is disposed within the receiving cavity of the mounting cover 122. The top of the outer cover 121 is also provided with a flip cover 1211 that is flipped and connected thereto. Opening the flip cover 1211 exposes the second end of the straw 64 for easy drinking by the user.

[0040] Furthermore, referring to Figure 2 , 3One side of the mounting cover 122 is rotatably connected to the extraction chamber 50. That is, the mounting cover 122 and the outer cover 121 as a whole can be flipped relative to the extraction chamber 50, thereby opening or closing the extraction chamber 50 and the inner chamber 20. A first bearing 124 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. Because of the first bearing between the inner cover 123 and the mounting cover 122, the inner chamber 20 and the inner cover 123 can rotate more smoothly relative to the mounting cover 122 under the drive of the drive mechanism 40.

[0041] Optionally, refer to Figure 3 The inner chamber 20 has an overflow groove at the edge of its opening. The inner cover 123 seals the inner chamber 20, preventing coffee from flying out. Simultaneously, the overflow groove at the edge of the inner chamber 20's opening allows the extracted coffee liquid to flow upwards along the groove and out of the inner chamber 20 during centrifugal extraction. The overflow groove has a small aperture, making it difficult for coffee grounds to overflow.

[0042] In one embodiment, the cold brew coffee cup also includes a handle 81, a control component 90, and a battery 91. The drive mechanism 40, the cooling mechanism 70, and the battery 91 are disposed within the housing 80. The cooling mechanism 70 is located below the cup body 10, and the battery 91 is located below the cooling mechanism 70. 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 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 cold brew coffee cup can be conveniently and quickly opened or closed by operating the control switch 92. (Refer to...) Figure 2 The cup handle 81 has a contact 93 at its top, and the cup lid 120 has another contact that matches the contact 93 at a corresponding position. When the cup lid 120 and the extraction chamber 50 are removed, the contact 93 disconnects, 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 10, the contact 93 connects, and the water pump 60 can be powered on and started. The battery 91 inside the outer casing 80 provides power to the various electrical components.

[0043] Furthermore, a temperature sensor is provided at the first end of the first tube 61, 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 101, and the control component 90 controls the cooling element 710 according to the outlet water temperature, thereby timely detecting and adjusting the water temperature.

[0044] Optionally, combined Figure 5In one embodiment, the cold brew coffee cup further includes a blade 21, a base 310, a first clutch 320, and a second clutch 330. The blade 21 is disposed within the inner chamber 20 and connected to the base 310. The base 310 is connected to the drive mechanism 40. One end of the base 310 extends out of the inner chamber 20 and is connected to the first clutch 320. The second clutch 330 is connected to the inner chamber 20. The first clutch 320 and the second clutch 330 can be connected or separated. By placing the blade 21 in the inner chamber 20, when the drive mechanism 40 rotates forward, the first clutch 320 and the second clutch 330 separate. That is, the base 310, the first clutch 320, and the blade 21 rotate in the first direction with the drive mechanism 40, while the second clutch 330 and the inner chamber 20 remain stationary. At this time, the blade 21 rotates at high speed relative to the inner chamber 20 to grind the coffee beans inside, obtaining freshly ground coffee powder. When the drive mechanism 40 reverses, the first clutch 320 connects with the second clutch 330, meaning the base 310, cutter 21, first clutch 320, second clutch 330, and inner chamber 20 are connected as a whole. As the drive mechanism 40 rotates in the second direction, the inner chamber 20 rotates at high speed, mixing with the low-temperature water in the liquid storage chamber 101, and centrifugally extracting the cold brew coffee liquid. The inner chamber 20 serves as both a grinding and extraction chamber, effectively saving space. The overall size of the cold brew coffee cup is smaller, making it more portable and convenient to use. In this embodiment, the third tube 63 is positioned above the middle of the cutter 21 to avoid the path of the cutter 21's rotation and prevent interference between them.

[0045] Reference Figure 5 Specifically, in one embodiment, the base 310 includes an upper cover 312, a base plate 316, and a boss 314, with one side of the base plate 316 connected to the boss 314. In this embodiment, the base plate 316 and the boss 314 are an integral structure. A second bearing 340 is sleeved on the boss 314. The first clutch 320 is rotatably connected to the base plate 316. Figure 4 The bottom wall of the inner chamber 20 protrudes inward to form a mounting platform, and the mounting platform has a mounting hole. The upper cover 312 covers the mounting platform and is connected to the tool 21. The boss 314 extends into the mounting hole and is connected to the upper cover 312. The upper cover 312 is located inside the inner chamber 20 and covers the mounting platform. The lower part of the upper cover 312 protrudes into the mounting hole and is connected to the boss 314. An installation space is formed in the area below the mounting platform. The bottom plate 316 is located below the bottom wall of the inner chamber 20. The upper cover 312 and the bottom plate 316 encapsulate the boss 314, the second bearing 340, the first clutch 320, and the second clutch 330 within the installation space.

[0046] Optionally, the first clutch 320 is a toothed block, with a rotating hole at one end and pointed teeth at the other. A protrusion is provided on the base plate 316, and the toothed block is rotatably mounted on the protrusion through the rotating hole. A rotational clearance is provided between the protrusion and the boss 314. When the drive mechanism 40 drives the base 310 and the first clutch 320 to rotate in the first direction, the tip of the first clutch 320 can rotate around the protrusion within the rotational clearance range. The tip of the first clutch 320 does not get stuck on the second clutch 330, and the two remain separated, preventing the inner compartment 20 from rotating with it. The second clutch 330 is a gear ring with multiple internal teeth, all facing the same direction. The first clutch 320 is located inside the gear ring. 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 clutch 320 and the boss 314. Through the action of the spring, after the base 310 rotates in the first direction, the first clutch 320 can return to a specific position, ensuring that it can engage with the second clutch 330 in the second direction.

[0047] In one embodiment, an elastic element 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 is provided in the base. The transmission element 42 is disposed within the limiting hole, and the elastic element abuts against the top of the transmission element 42 between the base 310 and the base. Specifically, the transmission element 42 is a polygonal element, and the limiting hole is a polygonal hole. The transmission element 42 engages with the limiting hole, thereby driving the base 310 to rotate. In other embodiments, the elastic element 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 prevents errors during assembly from causing improper installation of the drive mechanism and the clutch mechanism 30, ensuring a better connection between the drive mechanism 40 and the base 310.

[0048] The cold brew coffee cup described in at least one of the above embodiments combines grinding and cold brewing functions, effectively saving space. The overall size of the cold brew coffee cup is smaller, making it more portable and convenient to use. Furthermore, it extracts coffee using centrifugal force, resulting in a higher extraction rate and efficiency. During the coffee extraction process, the inner chamber rotates at high speed, and the coffee liquid mixes with air during the centrifugal motion, producing a layer of oily foam on the surface similar to a fluffy cake, enhancing the coffee's flavor. Moreover, the coffee extracted with low-temperature water has less acidity and astringency, resulting in a better coffee taste.
