Description

Technical Field

[0002] Modern automated beverage vending machine technology is widely used in public places such as shopping malls, airports, and office buildings, providing users with convenient, on-demand beverage service. These machines are typically equipped with multiple functions, including a variety of beverage options, one-touch operation, and rapid dispensing. They can store large quantities of ingredients, such as pre-packaged beverages, bottled or canned drinks, and even offer a choice of hot or cold beverages. Automated vending machines are designed to provide a fast and convenient consumer experience while reducing labor costs and improving service efficiency.

[0003] While existing automatic beverage machines offer a diverse selection of drinks, they remain limited in their coffee preparation capabilities. Most of these machines use pre-prepared coffee powder or concentrate; users simply select their beverage, and the machine adds the pre-made powder or concentrate to the cup and stirs it. While convenient and quick, this method struggles to match the taste and freshness of freshly ground coffee. Currently, most automatic beverage machines lack the ability to grind coffee beans on-site, failing to deliver the unique flavor and freshness of freshly ground coffee. Therefore, a new technological solution is needed that enables on-site coffee bean grinding during the vending process to enhance the consumer's beverage experience. Summary of the Invention

[0016] This invention provides a name. The blower connected to the output end of the blower blows air into the grinding space. During the rotation of the upper grinding body, the blower rotates, and the blower blows air into the grinding space. The air blown into the grinding space blows the coffee powder attached to the inner wall of the grinding space out through the discharge pipe, thus cleaning the inside of the grinding space and the discharge pipe.

[0017] Since different types of coffee beans may enter the grinding mechanism, blowing out the ground coffee powder effectively prevents it from mixing with powder from previously ground beans. This prevents cross-contamination between different types of coffee beans and ensures that each batch of coffee powder retains its original flavor. Immediately removing residual coffee powder from the previous grind ensures that each brew uses fresh coffee powder, guaranteeing freshness and optimal taste.

[0018] Coffee beans are ejected from the discharge channel by centrifugal force, ensuring a more even distribution as they enter the grinding chamber, resulting in a more uniform grind. This uniform grind helps ensure consistent coffee powder fineness, thus improving coffee quality and flavor. Evenly distributed beans also make more effective contact with the grinding media, reducing grinding time and energy consumption. Furthermore, the even distribution of beans allows for a more balanced load on the upper and lower grinding media, helping to reduce mechanical wear and extend the machine's lifespan.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-15 The present invention provides a beverage machine with a coffee bean grinding function, including a machine shell 1, a coffee bean grinding mechanism 2, a coffee bean discharging mechanism 3, a paper cup transfer mechanism 4, a paper cup releasing mechanism 5, a first water injection mechanism 6, and a first stirring mechanism 7.

[0038] The machine casing 1 is provided with a dispensing port 101, which is used by the user to take away the beverage.

[0039] The coffee bean grinding mechanism 2 includes a lower grinding body 201, an upper grinding body 202, a first motor 203, a first gear 204, a second gear 205, a blower 206, a pipe 207, a feed pipe 208, a first mounting base 210, an air blowing pipe 211, and a discharge pipe 212. The lower grinding body 201 is mounted on the inner wall of the machine housing 1 via the first mounting base 210. The upper grinding body 202 is rotatably connected to the first mounting base 210. The lower grinding body 201 has a conical groove 2011. The upper grinding body 202 is conical and extends into the conical groove 2011, forming a grinding space 209 between the upper grinding body 202 and the conical groove 2011. The upper grinding body 202 has a grinding space 209 inside. The mounting cavity 2021 is in which the blower 206 is installed. The air pipe 211 is connected to the output end of the blower 206 and extends out of the mounting cavity 2021. The end of the air pipe 211 away from the blower 206 points towards the grinding space 209. The input end of the blower 206 is connected to the outside of the mounting cavity 2021 through the pipe 207. The second gear 205 is installed on the upper surface of the upper grinding body 202. The first gear 204 is installed on the output end of the first motor 203 and meshes with the second gear 205. The upper grinding body 202 is provided with a discharge channel 2022, which is connected to the feed pipe 208.

[0040] The first motor 203 drives the upper grinding body 202 to rotate. Specifically, the first motor 203 drives the first gear 204 to rotate, the first gear 204 drives the second gear 205 to rotate, and the second gear 205 drives the upper grinding body 202 to rotate. When coffee beans enter through the feed pipe 208, they enter the discharge channel 2022 of the upper grinding body 202. As the upper grinding body 202 rotates, the coffee beans are subjected to centrifugal force and are thrown out through the discharge channel 2022 under the action of centrifugal force, and then enter the grinding space 209. The upper grinding body 202 rotates relative to the conical groove 2011, and the coffee beans are ground in the grinding space 209. When the coffee beans are ground into powder, they are discharged through the discharge pipe 212. The blower 206 is started, and the air blowing pipe 211 connected to the output end of the blower 206 blows air into the grinding space 209. During the rotation of the upper grinding body 202, the air blowing pipe 211 is driven to rotate. Figures 4 to 7As shown, the grinding space 209 is a conical circumferential space. During the rotation of the air blower 211, the grinding space 209 is thoroughly blew air. The air blown into the grinding space 209 blows the coffee powder adhering to the inner wall of the grinding space 209 out through the discharge pipe 212, thus cleaning the interior of the grinding space 209 and the discharge pipe 212.

[0041] Since the coffee beans entering the coffee bean grinding unit 2 may be of different types, blowing out the ground coffee powder effectively prevents it from mixing with powder from previously ground coffee beans. This prevents cross-contamination between different coffee beans and ensures that each batch of coffee powder retains its original flavor. If coffee powder is not cleaned in time, it may attract insects or breed bacteria, affecting the hygiene and safety of the coffee. Using the blower tube 211 to blow air into the grinding space 209 achieves automatic cleaning, effectively maintaining the hygiene of the grinding space 209 and thus ensuring the hygiene and safety of the coffee. The flavor and aroma of coffee decay rapidly after grinding. By immediately cleaning away the residual coffee powder from the previous grind, it ensures that each brew uses fresh coffee powder, thus guaranteeing the freshness and optimal taste of the coffee.

[0042] Coffee beans are ejected from the discharge channel 2022 under centrifugal force, ensuring a more even distribution of beans as they enter the grinding chamber 209, resulting in a more uniform grind. Uniform grinding helps ensure consistent coffee powder fineness, thus improving coffee quality and flavor. Evenly distributed beans can more effectively contact the grinding media, reducing grinding time and energy consumption. Furthermore, the even distribution of beans allows for a more balanced load on the upper and lower grinding media 202, helping to reduce mechanical wear and extend the machine's lifespan.

[0043] The coffee bean dispensing mechanism 3 stores coffee beans, and its output port corresponds to the feed pipe 208. The paper cup transfer mechanism 4 is used to transfer paper cups. The paper cup release mechanism 5 stores multiple paper cups and is used to release paper cups onto the paper cup transfer mechanism 4. The first water injection mechanism 6 is used to inject water into the paper cups. The first stirring mechanism 7 is used to stir the beverage inside the paper cups.

[0044] Furthermore, the coffee bean dispensing mechanism 3 stores various types of coffee beans. As shown in Figure 14, the paper cup release mechanism 5 is located on the rear wall of the machine casing 1, the coffee bean dispensing mechanism 3 and the coffee bean grinding mechanism 2 are respectively located on the left side of the machine casing 1, the first water injection mechanism 6 is located between the paper cup release mechanism 5 and the coffee bean grinding mechanism 2, and the first stirring mechanism 7 is located between the coffee bean grinding mechanism 2 and the dispensing port 101. The paper cup transfer mechanism 4 is used to carry the paper cup and drive the paper cup to perform a circular motion. The coffee bean grinding mechanism 2, the coffee bean dispensing mechanism 3, the paper cup release mechanism 5, the first water injection mechanism 6, and the first stirring mechanism 7 are all located on the circular motion trajectory of the paper cup. During use, the paper cup release mechanism 5 releases the paper cup, which falls onto the paper cup transfer mechanism 4 under gravity. The paper cup transfer mechanism 4 then drives the paper cup to move in a circular motion. When the paper cup is below the first water injection mechanism 6, the first water injection mechanism 6 injects water into the paper cup. The paper cup transfer mechanism continues to drive the paper cup to move. When the paper cup moves to the bottom of the coffee bean grinding mechanism 3, the coffee bean discharging mechanism 3 supplies coffee beans to the coffee bean grinding mechanism 2. The coffee beans enter the feed pipe 208 of the coffee bean grinding mechanism 2 and are then ground. The ground coffee powder enters the paper cup through the discharge pipe 212. The paper cup continues to move. When it reaches the first stirring mechanism 7, the first stirring mechanism 7 stirs the coffee powder and water in the paper cup to fully mix the coffee powder and water. After stirring, the paper cup transfer mechanism 4 continues to drive the paper cup to rotate. When the paper cup moves to the dispensing port 101, the user can take the coffee.

[0045] In the coffee preparation process described above, when water is added to the cup before coffee grounds, the subsequently added coffee grounds can be more evenly dispersed in the water. This helps to extract the soluble substances in the coffee grounds more evenly, resulting in a more balanced coffee flavor. By adding water first and then slowly adding the coffee grounds, the extraction process can be better controlled, avoiding problems such as bitterness and over-extraction.

[0046] Specifically, a door panel 102 is hinged to the machine casing 1, and a loading port 101 is opened on the door panel 102. The door panel 102 is equipped with a display screen 103, a touch panel 104, a handle 105, and an electromagnetic lock 106. The electromagnetic lock 106 is used to lock the door panel 102 and the machine casing 1 together. The door panel 102 is arc-shaped. The touch panel 104 has a built-in controller for coordinating and controlling the operation of the coffee bean grinding mechanism 2, the coffee bean dispensing mechanism 3, the paper cup transfer mechanism 4, the paper cup releasing mechanism 5, the first water injection mechanism 6, and the first stirring mechanism 7. Users input commands through the touch panel 104, which is connected to the controller and converts the user's input into specific control signals. Through programming and algorithm optimization, the controller can precisely control the duration, speed, and force of each step, thereby achieving an efficient and consistent coffee-making process.

[0047] The controller achieves precise control of various machine components through integrated circuits and programming. In this embodiment, the controller includes a microprocessor and necessary software to process user input (such as selections via a touch panel) and control the coordinated operation of the coffee bean grinding mechanism, dispensing mechanism, paper cup transfer mechanism, etc., according to a preset algorithm. The control algorithm is based on the fundamental principles of electronic engineering and mechanical control, such as PID control and time series analysis, to ensure that machine components operate in a predetermined sequence and time intervals. These techniques are widely used in the field of automated control systems, and their effectiveness and reliability have been verified through various applications. In the specific application of a coffee machine, although the specific control requirements and environment may differ, the basic control principles and techniques are largely the same as in other automated systems. Therefore, the controller and its algorithmic control of the coffee machine's components can be considered techniques well-known to those skilled in the art.

[0048] This invention does not seek protection for the control program or related software algorithms. The focus of patent protection is on the physical components, mechanical structure, and operation of the coffee machine, rather than the embedded software or control logic. Further details will not be provided here.

[0049] Specifically, the coffee bean grinding mechanism 2 further includes a second motor 213, two first guide shafts 214, a first screw 215, and a connecting part 216; the two first guide shafts 214 are fixedly mounted on the first mounting base 210, the first screw 215 is rotatably mounted on the first mounting base 210, and the first screw 215 is located between the two first guide shafts 214; the second motor 213 is connected to one end of the first screw 215; the connecting part 216 is fixedly connected to the lower grinding body 201; the first screw 215 passes through the connecting part 216 and is threadedly connected to the connecting part 216.

[0050] The second motor 213 is started, driving the first screw 215 to rotate. The rotation of the first screw 215, through the connecting part 216, causes the lower grinding body 201 to move up and down. The two first guide shafts 214, through the connecting plate 216, guide the movement of the lower grinding body 201, ensuring smooth and stable movement. The grinding space 209 can be adjusted by changing the distance between the lower grinding body 201 and the upper grinding body 202. When the grinding space 209 is smaller, the coffee powder ground by the coffee bean grinding mechanism 2 becomes finer. A finer grind extracts more flavor and aroma, making the coffee more delicious. Users can adjust the grind level according to personal taste preferences or specific coffee types. Adjusting the grinding space 209 allows for precise control of the coffee bean grind level. This is crucial for different types of coffee preparation (such as espresso, Americano, etc.), as different preparation methods require coffee powder of different fineness. Specifically, a mounting ring 217 is fixedly mounted on the first mounting base 210. The inner wall of the mounting ring 217 has a groove 218, and the upper grinding body 202 has a protrusion 219, which is rotatably connected to the groove 218. When the second gear 205 drives the upper grinding body 202 to rotate, the rotation of the upper grinding body 202 causes the protrusion 219 to rotate, and the protrusion 219 rotates relative to the groove 218. The cooperation between the protrusion 219 and the groove 218 ensures the stability of the rotation of the upper grinding body 202, thereby ensuring the grinding quality and consistency of the coffee powder.

[0051] Specifically, a funnel 220 is provided at the upper end of the feed pipe 208, and the funnel 220 corresponds to the output port of the coffee bean dispensing mechanism 3. The shape and position of the funnel 220 can effectively guide coffee beans from the coffee bean dispensing mechanism 3 into the feed pipe 208, reducing coffee bean spillage and waste.

[0052] Specifically, the discharge channel 2022 slopes downwards from the inside out; this allows the coffee beans to pass through the discharge channel 2022 with the help of gravity, thereby accelerating the discharge process. The downward slope helps ensure smooth movement of the coffee beans, reducing the possibility of blockage, and utilizes gravity to assist the movement of the coffee beans to a certain extent, thus improving discharge efficiency. The grinding space 209 gradually decreases in size from top to bottom, ensuring that the coffee beans are gradually pushed into a narrower space during grinding, thereby increasing the grinding intensity. As the grinding space decreases, the contact between coffee beans and between coffee beans and the grinding media becomes more frequent and closer, resulting in a finer grinding effect.

[0053] Specifically, the coffee bean dispensing mechanism 3 includes a mounting frame 301, a rotating shaft 302, a container 303, a tube 304, a third motor 305, a conveying shaft 306, a spiral blade 307, a cover 308, a fourth motor 309, and a retaining ring 311. The mounting frame 301 is fixedly connected to the rotating shaft 302. The mounting frame 301 is provided with multiple mounting parts 310. The tube 304 is installed in the mounting parts 310. The mounting parts 310 are arranged in a ring around the axis of the rotating shaft 302. The upper end of the tube 304 is fixedly connected to the container 303. The cover 308 is detachably connected to the container 303. The third motor 305 is mounted on the upper surface of the cover 308. The conveying shaft 306 is rotatably connected to the cover 308. The upper end of the conveying shaft 306 passes through the cover 308 and is connected to the output end of the third motor 305. The spiral blade 307 is disposed on the conveying shaft 306 and extends into the tube 304, fitting against the inner wall of the tube 304. The blocking ring 311 is disposed at the lower end of the tube 304. The upper end of the rotating shaft 302 is rotatably connected to a second mounting base 8, which is fixedly connected to the top wall of the machine housing 1. The fourth motor 309 is mounted on the second mounting base 8, and the output end of the fourth motor 309 is connected to the rotating shaft 302 and is used to drive the rotating shaft 302 to rotate.

[0054] The blocking ring 311 is made of rubber and has a round hole for coffee beans to pass through. The diameter of the round hole on the blocking ring 311 is smaller than the particle size of the coffee bean.

[0055] like Figure 8 and Figure 9As shown, in this embodiment, the coffee bean dispensing mechanism 3 contains five containers 303, each containing a type of coffee bean. A fourth motor 309 drives the rotating shaft 302 to rotate, and the rotation of the rotating shaft 302 causes the mounting frame 301 to rotate. The rotation of the mounting frame 301 drives the containers 303 to rotate through the tube 304. The feed pipe 208 of the coffee bean grinding mechanism 2 is below the circumferential motion trajectory of the tube 304. Users can select different types of coffee beans according to their preferences. The fourth motor 309 drives the rotating shaft 302 to rotate, and the rotation of the rotating shaft 302 drives the mounting bracket 301 to rotate until the container 303 containing the coffee beans selected by the user corresponds to the feed pipe 208. The third motor 305 drives the conveying shaft 306 to rotate, and the rotation of the conveying shaft 306 drives the spiral blade 307 to rotate. The rotation of the spiral blade 307 conveys the coffee beans, causing the coffee beans 307 to contact the blocking ring 311. When the coffee beans contact the blocking ring 311, the round hole on the blocking ring 311 deforms. With the rotation of the spiral blade 307, the coffee beans are squeezed out from the round hole on the blocking ring 311. The squeezed coffee beans fall into the feed pipe 208 and are then ground by the coffee bean grinding mechanism 2.

[0056] The paper cup transfer mechanism 4 includes a connecting plate 401 and a fifth motor 402. The fifth motor 402 is fixedly installed inside the machine housing 1. Paper cup receiving cavities 403 are respectively provided at both ends of the connecting plate 401. When the fifth motor 402 is started, it drives the connecting plate 401 to rotate, and the rotation of the connecting plate 401 causes the two paper cup receiving cavities 403 to perform circular motion. When one of the receiving cavities 403 carries the prepared coffee and moves to the dispensing port 101, the user can take the coffee. At this time, the other paper cup receiving cavity 403 is located under the paper cup release mechanism 5. The two paper cup receiving cavities 403 are used alternately.

[0057] The paper cup release mechanism 5 includes a cylinder 501, an upper connecting ring 502, a lower connecting ring 503, three rotors 504, a connecting column 505, a sixth motor 506, three third gears 507, a gear ring 508, and three connecting pieces 509. The cylinder 501 is fixedly installed on the inner wall of the machine housing 1. The upper connecting ring 502 is fixedly connected to the lower end of the cylinder 501. The upper connecting ring 502 is fixedly connected to the lower connecting ring 503 through the connecting column 505. The lower connecting ring 503 is connected to the three connecting pieces 509. The three connecting pieces 509 are C-shaped, and the bottom of the three connecting pieces 509 is used to support the gear ring 508. The gear ring 508 is rotatably disposed between the three connecting pieces 509. The motor 506 is fixedly connected to the upper connecting ring 502. The sixth motor 506 passes through the upper connecting ring 502 and is connected to one of the rotors 504. The three rotors 504 are rotatably mounted between the upper connecting ring 502 and the lower connecting ring 503. The three rotors 504 are respectively provided with helical protrusions 510. The lower ends of the three rotors 504 pass through the lower connecting ring 503 and are connected to the three third gears 507. The three third gears 507 are meshed with the gear ring 508. The inner diameter of the cylinder 501 is larger than the diameter of the paper cup. The three rotors 504 are arranged in a circle, and the distance between the three rotors 504 is equal to the diameter of the paper cup. The cylinder 501 is provided with a strip groove 5011.

[0058] The paper cups used in this embodiment are as follows: Figure 16 As shown, the device includes a cup body 13 and a cup rim retaining ring 14, which engages with a spiral protrusion 510. The pitch of the spiral protrusion 510 increases sequentially from top to bottom. During use, the paper cups are interlocked and positioned within the cylinder 501. When the paper cups need to be released, the sixth motor 506 is activated. The sixth motor 506 drives one of the rotors 504 to rotate. The driven rotor 504 drives the third gear 507 to rotate, and the gear ring 508 is driven to rotate by the third gear 507. Simultaneously, because the gear ring 508 is driven, all three third gears 507 rotate synchronously, thus causing all three rotors 504 to rotate. The rotation of the three rotors 504 conveys the paper cups downward through the spiral protrusions 510. As the pitch of the spiral protrusions 510 increases from top to bottom, the paper cup at the bottom side separates from the paper cup connected to it. When the paper cup at the bottom side is separated from the spiral protrusions 510, it falls down under the action of gravity and into the paper cup receiving cavity 403.

[0059] Specifically, the first water injection mechanism 6 includes a water tank 601, a pump 602, and a water injection pipe 603. The water tank 601 is located inside the machine casing 1, the pump 602 is connected to the water tank 601, and the output end of the pump 602 is connected to the water injection pipe 603. The water tank 601 stores drinking water. The pump 602 draws water from the water tank 601 and delivers it outward through the water injection pipe 603. When the paper cup moves to the output port of the water injection pipe 603, the pump 602 delivers water into the paper cup. In actual use, an existing water heating device can be installed in the water tank 601 to heat the water inside. If different water temperatures are to be set according to different user needs, an existing rapid-heating heater can be installed on the water injection pipe 603, and the water temperature of the beverage can be controlled by adjusting the rapid-heating heater.

[0060] The first stirring mechanism 7 includes a seventh motor 701, two mounting plates 702, two second guide shafts 703, a second screw 704, a lifting plate 705, an eighth motor 706, a stirring shaft 707, and stirring rods 708. The two mounting plates 702 are fixedly installed inside the machine housing 1. The two second guide shafts 703 are fixedly installed between the two mounting plates 702. The second screw 704 is rotatably installed between the two mounting plates 702. The seventh motor 701 is connected to one end of the second screw 704 and is used to drive the second screw 704 to rotate. The lifting plate 705 is slidably installed between the two second guide shafts 703. The second screw 704 passes through the lifting plate 705 and is threadedly connected to the lifting plate 705. The stirring shaft 707 is rotatably connected to the lifting plate 705. One end of the stirring shaft 707 is connected to the output end of the eighth motor 706. There are multiple stirring rods 708, which are disposed on the stirring shaft 707.

[0061] In the initial state, the lifting plate 705 is located on the upper side. When the cup moves to the lower end of the stirring shaft 707, the seventh motor 701 drives the second screw 704 to rotate. The rotation of the second screw 704 causes the lifting plate 705 to move downward. During the downward movement of the lifting plate 705, the two second guide shafts 703 guide the downward movement of the lifting plate 705, ensuring that the downward movement of the lifting plate 705 is smooth and stable. The downward movement of the lifting plate 705 causes the stirring shaft 707 to move downward. The stirring shaft 707 extends into the paper cup. The eighth motor 706 drives the stirring shaft 707 to rotate. The rotation of the stirring shaft 707 causes the stirring rod 708 to rotate. The stirring rod 708 stirs the coffee in the paper cup, so that the coffee powder and water are fully mixed.

[0062] Specifically, a beverage machine with a coffee bean grinding function also includes a beverage powder dispensing mechanism 9, a second water injection mechanism 10, and a second stirring mechanism 11; the beverage powder dispensing mechanism 9, the second water injection mechanism 10, and the second stirring mechanism 11 are all disposed inside the machine housing 1, and the beverage powder dispensing mechanism 9 is connected to the inner wall of the machine housing 1 through a third mounting base 12.

[0063] The beverage powder dispensing mechanism 9 has the same structure and working principle as the coffee bean dispensing mechanism 3. The only difference is that the beverage powder dispensing mechanism 9 does not include a retaining ring 311, but instead uses an existing gate valve (not shown in the figure) to intercept the beverage powder and prevent it from leaking out. The beverage powder dispensing mechanism 9 contains beverage powders of different flavors. During use, when beverage powder needs to be discharged, the gate valve opens, and the beverage powder falls into the paper cup as the spiral blades convey it.

[0064] The structure and working principle of the second water injection mechanism 10 are the same as those of the first water injection mechanism 6. The structure and working principle of the second stirring mechanism 11 are the same as those of the first stirring mechanism 7. Further details will not be provided here.

[0065] For the beverage paper cup process: After the paper cup falls into the receiving cavity 403, the receiving cavity 403 moves the paper cup to the second water injection mechanism 10, where water is injected into the paper cup. Then, the receiving cavity 403 moves the paper cup to the lower side of the beverage powder dispensing mechanism 9, where beverage powder is discharged into the paper cup. Next, the receiving cavity 403 moves the paper cup to the second stirring mechanism 11, where the second stirring mechanism 11 stirs the paper cup. Combined with... Figure 15 To further explain the coffee preparation process, in this embodiment, during the coffee preparation process, the paper cup rotates 108 degrees counterclockwise, and during the beverage preparation process, the paper cup rotates 180 degrees clockwise.

[0066] A method of using a beverage machine with a coffee bean grinding function, the method comprising the following steps: S1. Paper cup release: Paper cup release mechanism 5 releases the paper cup, causing the paper cup to fall onto the paper cup transfer mechanism 4 under the action of gravity; S2. The paper cup transfer mechanism 4 drives the paper cup to perform circular motion; S3. When the paper cup moves to below the first water injection mechanism 6, the first water injection mechanism 6 injects an appropriate amount of water into the paper cup; S4. The paper cup continues its circular motion to the bottom of the coffee bean grinding mechanism 3. At this time, the coffee bean discharging mechanism 3 supplies coffee beans to the coffee bean grinding mechanism 2. The coffee beans enter the feed pipe 208 of the coffee bean grinding mechanism 2, are ground into powder, and are discharged into the paper cup through the discharge pipe 212. S6. The paper cup continues to move to the first stirring mechanism 7. At this time, the first stirring mechanism 7 stirs the coffee powder and water in the paper cup so that the coffee powder and water are fully mixed. S7. After stirring is complete, the paper cup transfer mechanism 4 continues to rotate the paper cup until it moves to the dispensing port 101, at which point the user can take the coffee.
