Description

Technical Field

[0001] This invention relates to the field of coffee machine technology, specifically a high-precision feeding structure for raw materials in a vertical capsule coffee machine. Background Technology

[0002] Coffee is one of the world's three major beverages, and people around the world are increasingly fond of drinking it. Furthermore, coffee machines are becoming increasingly common, making coffee preparation more convenient and simple. The resulting "coffee culture" permeates every moment of life. Capsule coffee machines are one type of coffee machine. A capsule is a plastic capsule, similar to a pudding box, into which coffee powder is pre-filled and then filled with inert gas to preserve freshness.

[0003] The extraction mechanism of a capsule coffee machine includes an extraction head and a capsule cup. The capsule cup supports and holds the capsule during extraction. During extraction, the extraction head and capsule cup press against each other to hold the capsule in place. The extraction needle fixed to the extraction head punctures the capsule packaging and injects water for extraction. The extracted coffee is then collected into a beverage cup. After extraction, some residual coffee liquid will adhere to the extraction needle. Over time, this may contaminate the coffee liquid. Additionally, different coffee liquids may cross-contaminate in flavor, affecting the consumer's experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a high-precision feeding structure for raw materials in a vertical capsule coffee machine, thereby solving the problems mentioned in the background section.

[0005] The objective of this invention can be achieved through the following technical solutions:

A second sliding groove is provided on both opposite side walls of the mounting bracket. A movable piercing mechanism is provided inside the mounting bracket. The piercing mechanism includes a movable hollow needle located inside the mounting bracket. A slidable cleaning mechanism is provided inside the second sliding groove. The cleaning mechanism includes a slidable sponge block located below the hollow needle.

[0008] Preferably, the coffee capsule includes coffee powder, which is located in the upper half of the coffee capsule. The coffee capsule is fixed with axially distributed pins located below the coffee powder. A thin film is provided between the coffee powder and the pins. A flow guide groove is provided at the bottom of the pins, which is located in the lower half of the coffee capsule.

[0009] Preferably, the first slider has a uniformly distributed first circular hole, the side wall of the mounting bracket is provided with a fixedly connected water distribution valve, the water inlet of the water distribution valve is provided with a fixedly connected first water inlet pipe, the water outlet of the side wall of the water distribution valve is provided with a fixedly connected first water outlet pipe, the water outlet at the lower end of the water distribution valve is provided with a fixedly connected second water outlet pipe, and the second slide groove is located below the water distribution valve.

[0010] Preferably, the puncture mechanism includes an electric cylinder, an electric cylinder is fixedly connected to the inner wall of the top of the mounting frame, a first support plate is fixedly connected to the telescopic end of the electric cylinder, the first support plate is slidably connected to the mounting frame, a hollow needle is fixedly connected to the center of the bottom of the first support plate, a first water outlet pipe is fixedly connected to the hollow needle, and a pressure plate is provided below the first support plate.

[0011] Preferably, the bottom of the first support plate is provided with symmetrically fixed telescopic columns, and springs are wound around the outside of the telescopic columns. The other ends of the two telescopic columns are simultaneously fixedly connected to the pressure plate. A second circular hole is opened at the center of the pressure plate. The top of the pressure plate is provided with symmetrically fixedly connected uprights, which are located between the two telescopic columns. A contact sensor is fixedly connected inside the upright.

[0012] Preferably, the cleaning mechanism includes a rack, which is slidably connected to a second groove. A second water inlet pipe is provided at the top of the rack, and the second water inlet pipe is fixedly connected to a second water outlet pipe. A second support plate is fixedly connected to each of the two opposite side walls of the mounting frame.

[0013] Preferably, the top of the second support plate is provided with a rotatable gear that meshes with a rack, and the bottom of the second support plate is equipped with a fixedly connected second motor, the output shaft of the second motor being fixedly connected to the shaft of the gear.

[0014] Preferably, the rack is provided with a fixedly connected sponge block at the port inside the mounting frame, wherein the second water inlet pipe located at the opposite end of the water distribution valve is provided with a fixedly connected third water outlet pipe, and the inner wall of the mounting frame is provided with a fixedly connected rotating seat, which is located below the rack.

[0015] Preferably, the rotating base is provided with a rotatable wastewater tank, the top of the rotating base is provided with a fixedly connected third motor, the port of the wastewater tank is provided with a fixedly connected rotating block, the rotating block is rotatably connected to the rotating base, the bottom of the wastewater tank is provided with a drain pipe, the side wall of the wastewater tank is provided with a fixedly connected first magnet, the inner wall of the mounting bracket is provided with a fixedly connected second magnet, and the second magnet is located below the rack.

[0016] The beneficial effects of this invention are as follows: The piercing mechanism facilitates the piercing of the coffee capsule. The rotation of the first motor drives the threaded rod to rotate, and the first slider drives the mounting bracket to move downward. The pressure plate presses down on the top of the coffee capsule, and the electric cylinder stretches and drives the first support plate to move downward. The hollow needle also moves downward and passes through the second round hole. The pressure plate presses down on the coffee powder inside the coffee capsule, and the film between the coffee powder and the needle bends. The needle pierces the film, and at the same time, the hollow needle pierces the top seal of the coffee capsule and inserts into the coffee powder. During extraction, it ensures that there is no leakage at the contact point between the hollow needle and the capsule, thus increasing the sealing performance.

[0017] The cleaning mechanism facilitates cleaning of the hollow needle after puncture. When coffee powder is mixed with hot water, the first slider moves the mounting bracket upwards, the second motor rotates, driving the gear to rotate, and the rack slides along the second groove. The two sponge blocks move towards each other, locking the hollow needle and stopping. The electric cylinder extension rod compresses, moving the first support plate upwards, and the hollow needle moves upwards as well. The sponge blocks can wipe away the coffee liquid adhering to the outer wall of the hollow needle to prevent contamination by subsequent coffee liquids and to prevent cross-contamination between different coffee liquids, which would affect the consumer's use.

[0018] The wastewater tank facilitates self-cleaning of the sponge blocks. After a period of use, the two sponge blocks absorb some coffee liquid. After cleaning the hollow needle, the third motor is started. As the third motor rotates, the wastewater tank rotates towards the center of the mounting frame. The water distribution valve is opened, and hot water enters the rack along the second and third water outlets, flowing into the sponge blocks. The rack continues to slide into the mounting frame, squeezing the two sponge blocks. The squeezed wastewater flows into the wastewater tank and out through the drain pipe, cleaning the sponge blocks and allowing them to be reused. This keeps the hollow needle clean, is simple to operate, and saves labor costs. Attached Figure Description

In the initial state, the first magnet 682 and the second magnet 415 attract each other, and the wastewater tank 68 is fixed to the inner wall of the mounting frame 4. When it is necessary to clean the sponge block 66, the third motor 67 is started. The third motor 67 rotates, and the wastewater tank 68 rotates 90 degrees toward the center of the mounting frame 4. At this time, the wastewater tank 68 can catch the wastewater when the two sponge blocks 66 are squeezed.

[0040] Working principle:

[0041] When in use, after the operator selects the coffee, the internal storage and feeding mechanism of the capsule coffee machine pushes the bottom coffee capsule 3 into the capsule compartment 21, the first motor 13 is started, the first motor 13 rotates and drives the threaded rod 12 to rotate, the first slider 14 drives the mounting bracket 4 to move downward, the pressure plate 54 presses the top of the coffee capsule 3, the electric cylinder 51 is started, the electric cylinder 51 stretches and drives the first support plate 52 to move downward, the hollow pin 53 also moves downward and passes through the second round hole 541;

[0042] As the mounting bracket 4 continues to move downward, the pressure plate 54 presses the coffee powder 31 inside the coffee capsule 3, causing the film between the coffee powder 31 and the piercing pin 32 to bend. The piercing pin 32 punctures the film, and at the same time, the hollow pin 53 punctures the top seal of the coffee capsule 3 and inserts into the coffee powder 31. Hot water flows in from the first water inlet pipe 411, flows along the first water outlet pipe 412 into the hollow pin 53, and flows from the bottom of the hollow pin 53 into the coffee capsule 3. After the hot water and coffee powder 31 are fully mixed, they flow out from the guide channel 33 and then fall into the container that receives the coffee liquid.

[0043] Start the first motor 13 and the second motor 65. The first slider 14 drives the mounting frame 4 to move upward. The second motor 65 rotates, driving the gear 64 to rotate. The rack 61 also slides along the second slide groove 42. The two sponge blocks 66 move towards each other, and stop after locking the hollow pin 53. The electric cylinder 51 extends and compresses, driving the first support plate 52 to move upward. The hollow pin 53 also moves upward. The sponge blocks 66 can wipe away the coffee liquid attached to the outer wall of the hollow pin 53, making cleaning more convenient. When the mounting frame 4 rises to the top of the lifting frame 1, start the second motor 65. The two sponge blocks 66 move relative to each other and return to the initial position.

[0044] After a period of use, the two sponge blocks 66 absorb a certain amount of coffee liquid. After cleaning the hollow pin 53, the third motor 67 is started. The third motor 67 rotates, and the wastewater tank 68 rotates 90 degrees towards the center of the mounting frame 4. The water distribution valve 41 is opened, and hot water enters the rack 61 along the second water outlet pipe 413 and the third water outlet pipe 414, flowing into the sponge block 66. The rack 61 continues to slide into the mounting frame 4, and the two sponge blocks 66 are squeezed. The squeezed wastewater flows into the wastewater tank 68 and flows out from the drain pipe 69. The sponge block 66 is clean and can be used again. The wastewater tank 68 rotates to the initial position and is fixed to the inner wall of the mounting frame 4 by mutual attraction between the first magnet 682 and the second magnet 415, ready for the next cleaning and use.
