[0025] 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.

[0026] The specific embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0027] Reference Figure 1-5An embodiment of the present invention provides a grinding disc adjustment structure, including a support assembly 10, a motor 20, a first grinding disc 41, a second grinding disc 42, a connecting member 31, and a rotating cylinder 32. The motor 20 is mounted on the support assembly 10, and the first grinding disc 41 and the second grinding disc 42 are disposed opposite each other below the motor 20. The first grinding disc 41 is connected to the support assembly 10, and the second grinding disc 42 is drive-connected to the motor 20. The connecting member 31 is disposed above and connected to the motor 20, and the rotating cylinder 32 is axially limited within the support assembly 10 and threadedly connected to the connecting member 31. Axial limitation means that the rotating cylinder 32 cannot move axially, but can rotate around its axis. In this embodiment, the first grinding disc 41 is located above the second grinding disc 42, that is, the motor 20 drives the lower second grinding disc 42 to rotate, while the upper first grinding disc 41 remains stationary due to its connection to the support assembly 10. In other embodiments, the first grinding disc 41 may be positioned below the second grinding disc 42, that is, the motor 20 drives the second grinding disc 42 located above to rotate, while the first grinding disc 41 located below is connected to the support assembly 10 and remains stationary.

[0028] The grinding disc adjustment structure of this embodiment, by setting a first grinding disc 41 connected to the support assembly 10 and a second grinding disc 42 driven by the motor 20, when in use, the motor 20 starts, driving the second grinding disc 42 to rotate, crushing the coffee beans between the first grinding disc 41 and the second grinding disc 42. Compared with the traditional method of crushing by high-speed rotation of blades, the method of crushing coffee beans into powder by the relative movement of the first grinding disc 41 and the second grinding disc 42 can greatly reduce vibration and noise during the grinding process. Moreover, by setting a connector 31 connected to the motor 20 and a rotating drum 32 threadedly connected to the connector 31 above the motor 20, when the rotating drum 32 is rotated, since the rotating drum 32 is axially limited on the support assembly 10 and cannot move up and down, the connector 31 threadedly connected to the rotating drum 32, the motor 20 connected to the connector 31, and the second grinding disc 42 driven by the motor 20 move up and down, thereby adjusting the distance between the first grinding disc 41 and the second grinding disc 42, so as to flexibly adjust the coarseness of the coffee powder.

[0029] Optionally, in this embodiment, the outer wall of the connector 31 is provided with an external thread 311, and the inner wall of the rotating cylinder 32 is provided with an internal thread 322. The external thread 311 and the internal thread 322 cooperate to form a threaded connection between the connector 31 and the rotating cylinder 32. Thus, when the rotating cylinder 32 rotates but does not move axially, it drives the connector 31 to rotate along the thread and move axially up and down, thereby adjusting the gap between the second grinding disc 42 and the first grinding disc 41. When the second grinding disc 42 rises, the gap between the two becomes smaller, and the ground coffee powder particles become finer. When the second grinding disc 42 falls, the gap between the two becomes larger, and the ground coffee powder particles become coarser. In other embodiments, the inner wall of the connector 31 may also be provided with an internal thread 322, and the outer wall of the rotating cylinder 32 may be provided with an external thread 311. The external thread 311 and the internal thread 322 cooperate to form a threaded connection between the connector 31 and the rotating cylinder 32.

[0030] Furthermore, referring to Figure 1 and Figure 4 In one embodiment, the support assembly 10 includes a bean hopper body 120 and a cover 110. The bean hopper body 120 is provided with a bean inlet channel 102, and the cover 110 is provided with a bean inlet. Figure 3 A bean inlet cover 113 is provided at the bean inlet, which is opened or closed to open or close the bean inlet. A feeding port 401 is provided on the first grinding disc 41. Optionally, the middle of the first grinding disc 41 is hollow, and the middle of the top of the first grinding disc 41 is the feeding port 401. The cover 110 is placed on the bean hopper body 120. One end of the bean feeding channel 102 is connected to the bean inlet, and the other end is connected to the feeding port 401 of the first grinding disc 41. The opposite end faces of the first grinding disc 41 and the second grinding disc 42 are grinding surfaces. Optionally, the two grinding surfaces have multiple grinding teeth near their edges, and the two grinding surfaces near their center are cones in opposite directions, forming a grinding cavity between the two cone-shaped grinding surfaces, which is connected to the feeding port 401. The grinding cavity is formed by two cones in opposite directions, increasing its volume to accommodate coffee beans and speeding up the grinding process. Coffee beans enter through the bean inlet, then fall through the bean inlet channel 102 to the feed inlet 401 and enter the grinding chamber. As the second grinding disc 42 rotates, the coffee beans in the grinding chamber gradually move to the grinding teeth on the grinding surface. Under the action of the grinding teeth, they are crushed into powder and overflow to the edge along the gaps between the grinding teeth.

[0031] Reference Figure 4 In one embodiment, the bean hopper body 120 and the cover body 110 are through-shaped in the middle, the motor 20 and the connector 31 are installed in the middle of the bean hopper body 120, and the rotating drum 32 is sleeved on the outer periphery of the connector 31. Optionally, combined with Figure 2 and Figure 5The lower outer periphery of the rotating cylinder 32 has a first protrusion 321. The middle part of the cover 110 presses against the first protrusion 321, axially limiting the rotating cylinder 32 to the middle part of the cover 110. During assembly, the rotating cylinder 32 is first threadedly connected to the connecting piece 31, and then the cover 110 is placed on the bean hopper 120. The middle part of the cover 110 presses against the first protrusion 321 of the rotating cylinder 32, so that the rotating cylinder 32 is limited between the cover 110 and the bean hopper 120, and can only rotate relative to the cover 110 and the bean hopper 120, but cannot move axially.

[0032] Reference Figure 1 , Figure 2 and Figure 5 In one embodiment, the grinding disc adjustment structure further includes a metal ring 33, a first elastic element 34, and a lever 35. The metal ring 33 is disposed below the first boss 321. The rotating drum 32 rotates by resting on the metal ring 33 via the first boss 321. The metal ring 33 has low friction, making the rotation of the drum 32 smoother. The bottom wall of the first boss 321 is provided with a plurality of circumferentially arranged slots 3211. The metal ring 33 has a clearance hole. The bean hopper body 120 is provided with a first mounting cavity. The first elastic element 34 is disposed in the first mounting cavity. One end of the lever 35 abuts against the first elastic element 34, and the other end extends through the clearance hole into the slot 3211. When the rotating drum 32 rotates relative to the metal ring 33, the lever 35 floats and changes height under the action of the first elastic element 34, constantly jumping and locking into different slots 3211 one by one. During the rotation, there is a tactile feel for gear adjustment. After the user adjusts the gear, the lever 35 locks into the corresponding slot 3211, keeping the rotating drum 32 in the current gear, thereby keeping the gap between the first grinding disc 41 and the second grinding disc 42 at the current distance, making it convenient for the user to adjust the grinding gear conveniently and flexibly.

[0033] Furthermore, referring to Figure 1 , Figure 2 and Figure 5 In one embodiment, the grinding disc adjustment structure further includes a plurality of second elastic elements 36, and a plurality of second mounting cavities 312 are spaced apart on the outer periphery of the connecting member 31. The second elastic elements 36 are disposed within the second mounting cavities 312, and the bottom wall of the metal ring 33 abuts against the second elastic elements 36. Optionally, in this embodiment, there are three second elastic elements 36. The three second elastic elements 36 are evenly spaced and supported below the metal ring 33. In other embodiments, four, five, or other types of second elastic elements 36 may also be used. By supporting the metal ring 33 with the second elastic elements 36, the second elastic elements 36 continuously press against the metal ring 33 during the lifting and lowering process of the connecting member 31, making the rotation of the rotating drum 32 relative to the metal ring 33 more stable.

[0034] Furthermore, referring to Figures 1 to 5In one embodiment, the grinding disc adjustment structure further includes a knob cylinder 37, which is sleeved on the outer periphery of the rotating cylinder 32 and can drive the rotating cylinder 32 to rotate. (See reference...) Figure 2 The inner wall of the knob cylinder 37 is provided with a first engaging portion, and the outer wall of the rotating cylinder 32 is provided with a second engaging portion 323 that matches the first engaging portion. Through the cooperation of the first engaging portion and the second engaging portion 323, the rotation of the knob cylinder 37 drives the rotating cylinder 32 to rotate synchronously. Optionally, in this embodiment, the first engaging portion is a groove, and the second engaging portion 323 is a protruding ridge. In other embodiments, the first engaging portion is a protruding ridge, and the second engaging portion 323 is a groove. The protruding ridge is engaged in the groove, thus engaging the knob cylinder 37 and the rotating cylinder 32 together. In this embodiment, the inner wall of the knob cylinder 37 is covered with grooves, and the outer wall of the rotating cylinder 32 is provided with multiple protruding ridges at intervals. When the knob cylinder 37 is fitted onto the rotating cylinder 32, the protruding ridges can be quickly engaged in the grooves, making assembly convenient and the connection stable.

[0035] Furthermore, referring to Figure 2 and Figure 5 The lower outer periphery of the knob cylinder 37 has a second boss 371. (Combined) Figure 4 The cover 110 includes an outer cover 111 and an inner cover 112 connected to each other. The inner cover 112 is snapped into the bean hopper body 120, and the outer cover 111 is fitted over the inner cover 112. The inner cover 112 has a first limiting part 1121 in the middle, which presses against the first protrusion 321. The outer cover 111 has a second limiting part 1111 in the middle, which presses against the second protrusion 371. During assembly, first, the inner cover 112 is placed on the bean hopper body 120 and the two are snapped together. The first limiting part 1121 in the middle of the inner cover 112 presses against the first protrusion 321 of the rotating cylinder 32, limiting the axial movement of the rotating cylinder 32. Then, the knob sleeve is placed on the outside of the rotating cylinder 32, and the first and second snap-fit ​​parts are snapped together to connect the knob cylinder 37 and the rotating cylinder 32. Next, the outer cover 111 is placed on the outside of the inner cover 112 and the two are snapped together. The second limiting part 1111 in the middle of the outer cover 111 presses against the second protrusion 371 of the knob cylinder 37, limiting the axial movement of the knob cylinder 37. The upper part of the knob cylinder 37 extends out of the cover body 110, making it convenient for the user to operate the knob cylinder 37 to rotate, thereby driving the rotating cylinder 32 to rotate synchronously to adjust the height position of the connecting piece 31 and the second grinding disc 42.

[0036] Optionally, refer to Figure 4 and Figure 5 In one embodiment, the outer wall of the knob cylinder 37 is provided with anti-slip texture 372. The anti-slip texture 372 prevents slippage and provides a better feel for the user when adjusting the gear.

[0037] Furthermore, referring to Figure 4 and Figure 5 In one embodiment, the grinding disc adjustment structure further includes a mounting chamber 38, an operation panel 51, and a control component 52. The mounting chamber 38 is connected to the upper part of the connector 31, and the operation panel 51 is mounted on the top of the mounting chamber 38 and located inside the knob cylinder 37. The control component 52 is disposed within the mounting chamber 38 and is electrically connected to the operation panel 51 and the motor 20. The operation panel 51 can be a touchscreen or buttons, etc. The space of the mounting chamber 38 can accommodate the control component 52, such as a PCB, circuitry, etc. Information is processed through the control component 52, and the motor 20 is controlled to start grinding under the command of the operation panel 51.

[0038] Furthermore, referring to Figure 1 and Figure 2 The control panel 51 has scale lines 510 arranged around its circumference, and the knob cylinder 37 has an indicator 373 that matches the scale lines 510. During the rotation of the knob cylinder 37, the indicator 373 points to different scale lines 510, which makes it convenient for the user to quickly determine the grinding level, so as to accurately adjust the gap between the first grinding disc 41 and the second grinding disc 42, thereby accurately controlling the coarseness of the coffee powder.

[0039] Furthermore, referring to Figure 4 In one embodiment, the bean hopper 120 includes a separate outer shell 122 and a main body 124, with the outer shell 122 fitted over the main body 124. A shock-absorbing pad 126 is provided between the outer shell 122 and the main body 124. By configuring the bean hopper 120 as a split structure, the vibration generated when the motor 20 is running is transmitted to the main body 124 and then significantly reduced by the shock-absorbing pad 126, thereby reducing the vibration of the outer shell 122, further reducing the noise transmitted to the outside, and improving the user experience.

[0040] Furthermore, the inner cover 112 is snapped into the outer casing 122, and the motor 20 is mounted on the main body 124. Optionally, the top of the outer casing has a recessed groove, in which the inner cover 112 is snapped. The inner cover 112 can also be locked onto the outer casing with screws, ensuring a secure connection between the two. Furthermore, the outer wall of the inner cover 112 has a locking position, and the inner wall of the outer cover 111 has a hook; through the engagement of the hook and the locking position, the inner cover 112 and the outer cover 111 are securely connected together.

[0041] Reference Figure 3 and Figure 4This application also provides a coffee cup in one embodiment, including a cup body 2 and a grinding disc adjustment structure as described in any of the above embodiments. The grinding disc adjustment structure is disposed inside the cup body 2, and the support component 10 is detachably connected to the cup body 2 and forms a liquid storage space at the lower part of the cup body 2. The support component 10 is used to connect to the cup body 2. In this embodiment, the cup body 2 serves as a container, and the support component 10 is connected to the cup body 2 at the lower part of the cup body 2 to form a liquid storage space. In other embodiments, other containers, such as the body of a coffee machine, can also be used. The bottom of the cup body 2 is provided with an anti-slip pad to increase stability. The grinding disc adjustment structure not only has low noise but also allows for flexible adjustment of the coarseness of the coffee powder. The ground coffee powder is mixed with the liquid in the liquid storage space to produce coffee liquid.

[0042] Reference Figure 1 , Figure 3 and Figure 4 In one embodiment, the coffee cup further includes a drive shaft 70, a centrifuge chamber 61, and a coffee chamber 62. One end of the drive shaft 70 is connected to the motor 20, and the other end is connected to the second grinding disc 42 and the centrifuge chamber 61. The centrifuge chamber 61 is fitted over the first grinding disc 41 and the second grinding disc 42. The coffee chamber 62 is fitted over the centrifuge chamber 61 and connected to the support assembly 10. The centrifuge chamber 61 has an overflow hole communicating with the coffee chamber 62, and the bottom wall of the coffee chamber 62 has a liquid outlet hole. The drive shaft 70 is located below the motor 20 and is connected to the motor 20, with the end of the drive shaft 70 away from the motor 20 connected to the second grinding disc 42 and the centrifuge chamber 61. The drive shaft 70 has a thicker upper section and a thinner lower section, with its upper diameter larger than that of the motor 20. The upper part of the drive shaft 70 is fitted over the lower part of the motor 20, and the two are fastened together with screws and other parts. When the motor 20 starts, it drives the drive shaft 70 to rotate synchronously, which in turn drives the second grinding disc 42 and the centrifuge chamber 61 to rotate. The coffee powder ground by the grinding disc adjustment structure enters the centrifuge chamber 61. The centrifuge chamber 61 rotates at high speed, and the coffee powder and liquid are mixed and centrifuged to extract coffee. The coffee enters the coffee chamber 62 through the overflow hole 601 of the centrifuge chamber 61. Specifically, the side wall of the centrifuge chamber 61 has multiple overflow holes 601. The bottom wall of the coffee chamber 62 has a liquid outlet hole. The coffee liquid in the coffee chamber 62 flows into the cup body 2 through the liquid outlet hole. Optionally, a one-way valve is provided at the liquid outlet hole of the coffee chamber 62. The one-way valve only allows coffee liquid to flow from the coffee container 62 into the cup body 2, and does not allow liquid to enter the coffee container 62 from the cup body 2. This prevents liquid from flowing back into the grinding mechanism when the coffee cup is tilted, which could damage internal parts or contaminate the coffee liquid. The coffee container 62 is connected to the bean container 120 to form a whole, and the coffee container 62 surrounds the centrifugal chamber 61, enclosing the high-speed rotating centrifugal chamber 61 and providing safety protection.

[0043] Furthermore, referring to Figure 4 In one embodiment, the coffee cup further includes a first bearing 71 and a second shock-absorbing pad 126. The first bearing 71 is sleeved on the outer periphery of the drive shaft 70, and the outer ring of the first bearing 71 is pressed onto the main body 124 by the second shock-absorbing member. The outer wall of the drive shaft 70 is connected to the inner ring of the first bearing 71 and rotates relative to its outer ring, improving the stability and concentricity of the transmission process. The outer ring of the first bearing 71 is connected to the main body 124 by the second shock-absorbing pad 126, absorbing vibrations during the transmission process and further reducing noise.

[0044] Specifically, refer to Figure 4 In one embodiment, the coffee cup further includes a first connecting seat 74, a second connecting seat 75, and a transmission seat 76. The second grinding disc 42 is connected to the first connecting seat 74, and the centrifuge chamber 61 is connected to the second connecting seat 75. The first connecting seat 74 is connected to the transmission shaft 70 via the transmission seat 76. The second connecting seat 75 is detachably connected to the first connecting seat 74. The inner side of the transmission seat 76 engages with the lower part of the transmission shaft 70, and the outer side of the transmission seat 76 engages with the first connecting seat 74. The first connecting seat 74 and the second connecting seat 75 are detachably connected, making it easy to remove the second connecting seat 75 and the centrifuge chamber 61 connected thereto for cleaning the centrifuge chamber 61. The bottom outer periphery of the second connecting seat 75 is provided with a mounting groove, through which the centrifuge chamber 61 is secured to the second connecting seat 75.

[0045] Optionally, the first connecting seat 74 is provided with a first magnetic attractor, and the second connecting seat 75 is provided with a second magnetic attractor. The first magnetic attractor and the second magnetic attractor have opposite magnetic properties. The first connecting seat 74 and the second connecting seat 75 are connected together by the magnetic force of the first magnetic attractor and the second magnetic attractor, allowing for quick disassembly during cleaning to remove coffee grounds from the centrifuge chamber 61. Furthermore, the second magnetic attractor and the first magnetic attractor are not in direct contact; a plastic part separates them to reduce the magnetic force and facilitate better separation of the second magnetic attractor from the first magnetic attractor.

[0046] Furthermore, referring to Figure 4 In one embodiment, a support base 622 is formed by an inward protrusion in the bottom wall of the coffee compartment 62, and the second connecting seat 75 is sleeved on the support base 622. This arrangement allows the second connecting seat 75 to rotate around the support base 622 under the drive of the transmission shaft 70, resulting in better stability during transmission and higher overall concentricity.

[0047] Furthermore, referring to Figure 4In one embodiment, a receiving cavity is formed below the support base 622, and the transmission base 76 extends into the receiving cavity. A second bearing 72 is provided in the receiving cavity, and the second bearing 72 is sleeved on the outer periphery of the transmission base 76. The transmission base 76 extends from the first connecting base 74 into the receiving cavity below the coffee compartment 62, and the second bearing 72 is sleeved at the part of the transmission base 76 located in the receiving cavity. The outer wall of the transmission base 76 contacts the inner ring of the second bearing 72 and rotates relative to its outer ring, further improving the stability and concentricity of the transmission process.

[0048] Reference Figure 1 , Figure 3 and Figure 4 Furthermore, in one embodiment, the coffee cup further includes a water guide pipe 81 and a water pump 80. The water pump 80 is mounted on the support assembly 10 and communicates with the water guide pipe 81. The first end of the water guide pipe 81 passes sequentially through the connector 31, the motor 20, the drive shaft 70, the first grinding disc 41, the second grinding disc 42, the centrifuge chamber 61, and the coffee chamber 62 before extending into the liquid storage space. The second end of the water guide pipe 81 passes through the support assembly 10 and extends into the centrifuge chamber 61. Figure 4 The connector 31 has a through hole on its side, through which the motor 20, drive shaft 70, first grinding disc 41, second grinding disc 42, centrifuge chamber 61, and coffee chamber 62 are all connected. The motor 20 can be an existing hollow motor 20. The first end of the water guide pipe 81 passes through the through hole of the connector 31 and the middle of the motor 20, drive shaft 70, first grinding disc 41, second grinding disc 42, centrifuge chamber 61, and coffee chamber 62, and is inserted into the liquid storage space. The second end of the water guide pipe 81 passes through the main body 124 and extends into the centrifuge chamber 61. A water pump 80 is located between the first and second ends of the water guide pipe 81. The water pump 80 is mounted on the main body 124. The water pipe 81 is long enough that the water pump 80 starts, drawing the liquid from the storage space upwards into the centrifuge chamber 61. Inside the centrifuge chamber 61, the high-speed rotating coffee powder mixes with the liquid, centrifuging to extract coffee. The extracted coffee flows through the overflow hole into the coffee chamber 62, and then back into the storage space. This cycle repeats multiple times to produce a coffee beverage with excellent flavor. Adding ice water to the storage space allows for the preparation of even better-tasting cold brew or iced coffee using the coffee cup of this embodiment.

[0049] Optionally, the water pump 80 is a peristaltic pump, in which the liquid only enters the pipes of the peristaltic pump and does not enter its diaphragm, making it more hygienic. The water pump 80 is electrically connected to the control component 52, which processes information and controls the coffee cup's extraction mode, water pump 80 start, motor 20 start, timer, automatic cleaning function, etc., under the instructions of the operation panel 51.

[0050] Furthermore, referring to Figure 4A third bearing 73 is provided between the transmission seat 76 and the water guide pipe 81. The third bearing 73 is sleeved on the water guide pipe 81 below the transmission shaft 70. The inner wall of the transmission seat 76 contacts the outer ring of the third bearing 73 and rotates relative to its inner ring. On the one hand, this can prevent the water guide pipe 81 from being worn during the rotation of the transmission seat 76, and on the other hand, it can improve the stability and concentricity of the transmission process.

[0051] In one embodiment, reference is made to Figure 4 The coffee cup also includes an adapter 64 and a sealing cap 65. The water guide tube 81 includes an inner tube and an outer tube. The sealing cap 65 covers the opening of the receiving cavity. One end of the adapter 64 is located inside the receiving cavity and communicates with the inner tube, while the other end of the adapter 64 extends outside the sealing cap 65 and communicates with the outer tube. Connecting the inner and outer tubes of the water guide tube 81 via the adapter 64 facilitates the introduction of water from the liquid storage space of the cup body 2 into the centrifuge chamber 61 from bottom to top, and also facilitates the disassembly of the outer tube for cleaning. One end of the adapter 64 is located inside the receiving cavity and abuts against the lower outer ring of the second bearing 72. The sealing cap 65 rests on the adapter 64 and is fixed to the bottom of the coffee chamber 62 using ultrasonic technology, sealing the adapter 64 and the second bearing 72, providing good waterproofing and sealing. The adapter 64 uses a silicone connector. The outer water tube extends to the bottom wall of the cup body 2 to maximize the extraction of liquid from the cup body 2 into the centrifuge chamber 61.

[0052] Optionally, the cover 110 is provided with a conductive interface electrically connected to the control component 52. The conductive interface provides power to the coffee cup. In other embodiments, the coffee cup also includes a battery, which is disposed on the side of the bean hopper 120 and electrically connected to the control component 52. The battery provides power to the coffee cup, and the conductive interface can also charge the battery.

[0053] Optionally, the cover 110 is also provided with a start / stop button electrically connected to the control component 52. The start / stop button controls the coffee cup to turn on and off, making operation intuitive and simple.

[0054] The coffee cup of at least one of the above embodiments has the following coffee making process: the grinding disc adjustment structure and the centrifugal chamber 61 and coffee chamber 62 inside the cup body 2 are taken out, ice water is added to the cup body 2, and then the grinding disc adjustment structure and the centrifugal chamber 61 and coffee chamber 62 are put into the cup body 2. The outer shell 122 is connected to the cup body 2, the grinding disc adjustment structure and the centrifugal chamber 61 and coffee chamber 62 are suspended in the cup body 2, and the water pipe 81 is inserted into the ice water in the liquid storage space. Open the bean hopper lid 113 and put in coffee beans. The coffee beans enter the grinding chamber through the bean inlet channel 102. The first magnetic suction component and the second magnetic suction component couple the first connecting seat 74 and the second connecting seat 75 together. Start the motor 20 to drive the drive shaft 70, drive seat 76, first connecting seat 74, second grinding disc 42, second connecting seat 75 and centrifuge chamber 61 to rotate together. The first grinding disc 41 and the second grinding disc 42 rotate relative to each other to crush the coffee beans. The crushed coffee powder enters the centrifuge chamber 61 through the gap between the first grinding disc 41 and the second grinding disc 42. The peristaltic pump passes through the water pipe. 81 pumps water from cup 2 upwards and sprays it into centrifugal chamber 61, impacting the coffee powder in centrifugal chamber 61. The coffee liquid is extracted under centrifugal force and flows into coffee chamber 62 through the overflow hole of centrifugal chamber 61. The extraction rate of coffee is high through centrifugal force. During centrifugal extraction, the coffee liquid mixes with air, and a layer of oil foam similar to a fluffy cake is produced on the surface of the coffee liquid, resulting in an iced coffee drink with excellent taste. Furthermore, the gap between the first grinding disc 41 and the second grinding disc 42 can be flexibly adjusted through the grinding disc adjustment structure to achieve noise reduction grinding and flexible adjustment of the coarseness of coffee powder.
