Description

Technical Field

[0001] The utility model relates to the technical field of capsule coffee machines, in particular to an extraction device for a vertical capsule coffee machine. Background Technique

[0002] A capsule coffee machine pre-loads coffee powder into a plastic capsule and then fills it with nitrogen for freshness preservation. When in use, the capsule is loaded into a dedicated capsule coffee machine to obtain a cup of coffee.

[0003] At present, the common extraction devices of capsule coffee machines mainly rely on a spring mechanism to move up and down. Manually pushing the handle drives the puncturing needle to tilt downward to puncture the capsule and inject water. During the operation, it is easy to cause liquid leakage, so that the capsule coffee machine is contaminated and needs to be frequently disassembled and cleaned. Moreover, the manual method is prone to the deviation of the capsule during actual use, which affects the normal operation of the handle. It is necessary to forcefully pull the handle, resulting in the capsule being damaged and causing more liquid leakage. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and to propose an extraction device for a vertical capsule coffee machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An extraction device for a vertical capsule coffee machine includes a chassis and capsules. The chassis is a vertical box body. A light box sheet is arranged at the top of the chassis. A fixing plate is installed in the middle of the chassis. A material barrel is rotatably installed on one side of the fixing plate. A plurality of card slots are evenly formed in the side wall of the material barrel. A plurality of capsules are slidably connected in each card slot. A fixed slide rail is fixedly installed at the top end of the fixing plate close to one side of the opening of the chassis. An extraction mechanism is slidably connected to the side of the fixed slide rail close to the material barrel. An injection box is fixedly installed above the fixing plate at one end of the fixed slide rail through a mounting plate.

[0007] Preferably, a motor is fixedly installed at the top of the material barrel, and an output shaft of the motor is fixedly connected to an internal rotating shaft of the material barrel.

[0008] Preferably, a plurality of release devices corresponding to the card slots one by one are evenly arranged at the bottom of the material barrel, and the release devices are electrically connected to a controller built in the external chassis.

[0009] Preferably, a lifting platform is installed on the other side of the fixing plate. A rotating rod is rotatably installed at the bottom of the lifting platform, and an electric gripper is installed at the end of the rotating rod.

[0010] Preferably, the extraction mechanism includes an extraction cylinder and an installation groove. One side of the fixed slide rail is slidably connected with an electric slider. The side wall of the electric slider is fixedly connected with the extraction cylinder. A number of thimbles are evenly arranged at the bottom of the extraction cylinder. A blanking port is opened at the center of the bottom of the extraction cylinder. An installation groove is opened on one side close to the material bucket at the bottom of the blanking port. A disc-shaped slider is slidably connected in the installation groove. A fixed block sleeved on the outer wall of the blanking port is fixedly installed on the outside of the installation groove. Through grooves penetrating each other are opened on both sides of the fixed block. Two guide rods penetrating both sides of the slider are fixedly installed on both sides of the through groove. Springs are sleeved on both guide rods.

[0011] Preferably, a chute is opened on the fixed plate on one side of the fixed slide rail, and two matching grooves are symmetrically opened on the side walls on both sides of the chute.

[0012] Preferably, an electric telescopic rod is arranged inside the injection box. A pipeline is connected to the top of the injection box. A protective cover is movably installed at the end of the telescopic end of the electric telescopic rod at the bottom of the injection box. An injection needle is installed at the center of the protective cover, and the injection needle is communicated with the pipeline.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By setting the extraction mechanism, the extraction mechanism can move the capsule through the drive of the fixed slide rail and the electric slider to realize the automatic filling of the capsule and cooperate with the injection box for extraction operation. The capsule can be accurately conveyed below the injection box, and when the conveying is in place, the blanking port is opened through the cooperation of the matching groove and the slider. After the extraction is completed, when the electric slider drives the extraction cylinder to reset, the blanking port automatically closes, which can effectively reduce the leakage of the residual coffee liquid in the capsule.

[0015] By setting the injection box, the injection box is similar to the traditional puncturing needle. The injection needle is inserted into the capsule to inject drinking water for the extraction of coffee powder. The difference is that the injection box uses an automatic operation method to cooperate with the capsule and the extraction cylinder through the protective cover, so that the capsule is not easily offset during the extraction process, resulting in deformation of the capsule and more leakage. It can also prevent the coffee liquid from leaking through the puncture point after the injection needle punctures the capsule, effectively reducing the pollution of the capsule coffee machine and reducing the cleaning time. At the same time, with the push of the protective cover, the puncturing area of the thimble can be increased, so that the aluminum foil film of the capsule is fully punctured, and the coffee liquid can flow out fully, thereby reducing the waste of coffee powder and the residual coffee liquid in the extraction cylinder. And during the extraction process, the slider does not contact the coffee liquid, which can also prevent the coffee liquid from being polluted. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Refer to Figure 1-9, A vertical capsule coffee machine extraction device, including a chassis 1 and capsules 5. The chassis 1 is a vertical box body. A light box sheet is provided at the top of the chassis 1. A fixing plate 2 is installed in the middle of the chassis 1. A material bucket 3 is rotatably installed on one side of the fixing plate 2. A number of card slots are evenly opened on the side wall of the material bucket 3. A number of capsules 5 are slidably connected in each card slot. Above the fixing plate 2 near the opening of the chassis 1 at the top, a fixed slide rail 9 is fixedly installed. An extraction mechanism 10 is slidably connected to the side of the fixed slide rail 9 near the material bucket 3. Above the fixing plate 2 at one end of the fixed slide rail 9, an injection box 20 is fixedly installed through a mounting plate. The chassis 1 is filled with a new type of heat-insulating material, which can keep the internal water, etc. warm. A number of capsules 5 are pre-installed in the card slots on the side wall of the material bucket 3. Different types and flavors of coffee powder are packed in the capsules 5 in each card slot. The extraction mechanism 10 can move the capsules 5 through the drive of the fixed slide rail 9 and the electric slider 11 to achieve the automatic filling of the capsules 5 and cooperate with the injection box 20 for extraction operations. It can accurately convey the capsules 5 below the injection box 20 and open the material discharge port 14 through the action of the cooperation groove 15 when in place. After the extraction is completed, when the electric slider 11 drives the extraction cylinder 12 to reset, the material discharge port 14 automatically closes, which can effectively reduce the leakage of the residual coffee liquid in the capsules 5. The injection box 20 is similar to the traditional puncturing needle. The injection needle is inserted into the capsule 5 to inject drinking water for coffee powder extraction. The difference is that the injection box 20 uses an automatic operation method to cooperate with the capsule 5 and the extraction cylinder 12 through the protective cover 19, so that the capsule 5 is not easily displaced during the extraction process, resulting in deformation of the capsule 5 and more leakage. It can also prevent the coffee liquid from leaking through the puncture point after the injection needle punctures the capsule 5 through the protective cover 19, effectively reducing the pollution of the capsule coffee machine and reducing the cleaning time.

[0028] As a technical optimization scheme of the present utility model, a motor 4 is fixedly installed at the top of the material bucket 3, and the output shaft of the motor 4 is fixedly connected to the internal rotating shaft of the material bucket 3. The material bucket 3 rotates through the drive of the motor 4, and when the customer selects different flavors of coffee, the selected coffee capsule 5 can be rotated above the electric claw 8.

[0029] As a technical optimization scheme of the present utility model, a number of release devices corresponding to the card slots one by one are evenly arranged at the bottom of the material bucket 3, and the release devices are electrically connected to the controller built in the external chassis 1. The release devices can release the capsules 5 from the card slots one by one in sequence. Generally, the release is carried out by the contraction of the telescopic rod, and the capsule 5 can be blocked after elongation.

[0030] As a technical optimization solution of the present utility model, a lifting platform 6 is installed on the other side of the fixing plate 2. A rotating rod 7 is rotatably installed at the bottom of the lifting platform 6, and an electric gripper 8 is installed at the end of the rotating rod 7. When the lifting platform 6 rises and cooperates with the electric gripper 8, the released capsule 5 can be picked up, and the capsule 5 can be rotated above the extraction cylinder 12 through the rotating rod 7. At this time, when the lifting platform 6 descends and the electric gripper 8 releases the capsule 5, the capsule 5 can be placed in the extraction cylinder 12.

[0031] As a technical optimization solution of the present utility model, the extraction mechanism 10 includes an extraction cylinder 12 and an installation groove 17. An electric slider 11 is slidably connected to one side of the fixed slide rail 9. The side wall of the electric slider 11 is fixedly connected with the extraction cylinder 12. A plurality of thimbles 13 are evenly arranged at the bottom of the extraction cylinder 12. A material discharge port 14 is opened at the center of the bottom of the extraction cylinder 12. An installation groove 17 is opened on one side of the bottom of the material discharge port 14 close to the material bucket 3. A disc-shaped slider 171 is slidably connected in the installation groove 17. A fixed block 21 sleeved on the outer wall of the material discharge port 14 is fixedly installed outside the installation groove 17. Through grooves 22 penetrating through are opened on both sides of the fixed block 21. Two guide rods passing through both sides of the slider 171 are fixedly installed on both sides of the through groove 22. Springs 23 are sleeved on both guide rods. After the extraction cylinder 12 accommodates the capsule 5, the electric slider 11 drives the extraction cylinder 12 to slide the capsule 5 along the fixed slide rail 9 to the end of the chute 16. During the sliding process, both sides of the slider 171 slide along the mating groove 15 and can effectively close the bottom opening of the material discharge port 14 through the action of the spring 23. When approaching the end of the chute 16, the slider 171 slides to the end of the mating groove 15 and is limited. At this time, when the extraction cylinder 12 continues to slide, the slider 171 can be pushed out of the installation groove 17 through the mating groove 15 to open the material discharge port 14. At this time, the spring 23 is compressed by force. At this time, it is convenient for the coffee liquid extracted after injecting drinking water by the injection box 20 to flow out through the material discharge port 14. After the extraction is completed, the electric slider 11 drives the extraction cylinder 12 to reset. At this time, under the action of the spring 23, the slider 171 resets to close the material discharge port 14 to prevent the coffee liquid from leaking through the material discharge port 14, and during the extraction process, the slider 171 does not contact the coffee liquid, which can also prevent the coffee liquid from being contaminated.

[0032] As a technical optimization solution of the present utility model, a chute 16 is opened on the fixing plate 2 on one side of the fixed slide rail 9, and two mating grooves 15 are symmetrically opened on both side walls of the chute 16. The stroke of the chute 16 is greater than that of the mating groove 15, which is convenient for pushing the slider 171 out of the installation groove 17 through the mating groove 15 when the extraction cylinder 12 approaches the end of the chute 16, so as to realize the automatic opening of the material discharge port 14.

[0033] As a technical optimization solution of the present utility model, an electric telescopic rod is built into the injection box 20. A pipe 18 is connected to the top of the injection box 20. A protective cover 19 is movably installed at the end of the telescopic end of the electric telescopic rod at the bottom of the injection box 20. An injection needle is installed at the center of the protective cover 19, and the injection needle is communicated with the pipe 18. The injection box 20 is a common prior art, which is used in a capsule coffee machine to push the injection needle into the capsule 5 and perform a water injection operation. An electric telescopic rod is fixedly installed in the injection box 20. The telescopic end of the electric telescopic rod penetrates out of the injection box 20 and is fixedly connected to the top end of the protective cover 19. And the injection needle and the pipe 18 are connected by a hose. Then, the telescopic action of the electric telescopic rod can drive the protective cover 19 and the injection needle to move up and down, which is convenient for the injection needle to pierce the capsule 5 and inject the drinking water in the pipe 18 into the capsule 5 through the hose. After the extraction cylinder 12 and the capsule 5 are in place, the injection box 20 pushes the protective cover 19 and the injection needle to pierce the bottom of the capsule 5 and inject the drinking water. After the drinking water is injected, the pressure in the capsule 5 increases, and the aluminum foil film of the capsule 5 is pressed and expanded and can be pierced by a plurality of thimbles 13. The extracted coffee liquid can flow out to the blanking port 14. At the same time, with the push of the protective cover 19, the piercing area of the thimble 13 can be increased, so that the aluminum foil film of the capsule 5 is fully pierced, and the coffee liquid can flow out sufficiently, thereby reducing the waste of coffee powder and the coffee liquid residue in the extraction cylinder 12.

[0034] When the utility model is in use, a customer selects a required coffee flavor on the panel outside the machine case 1 and presses the start production button. At this time, the motor 4 drives the material barrel 3 to rotate, rotates the selected coffee capsule 5 above the electric gripper 8, and the releaser releases the capsule 5 from the card slot. The lifting platform 6 rises to cooperate with the electric gripper 8 to pick up the released capsule 5, and rotates the capsule 5 above the extraction cylinder 12 through the rotating rod 7. At this time, the lifting platform 6 descends and the electric gripper 8 releases the capsule 5 to place the capsule 5 in the extraction cylinder 12. After the extraction cylinder 12 accommodates the capsule 5, the electric slider 11 drives the extraction cylinder 12 to slide the capsule 5 along the fixed slide rail 9 to the end of the chute 16. During the sliding process, both sides of the slider 171 slide along the mating groove 15 and can effectively seal the bottom opening of the material discharge port 14 through the action of the spring 23. When approaching the end of the chute 16, the slider 171 slides to the end of the mating groove 15 and is limited. At this time, when the extraction cylinder 12 continues to slide, it can push the slider 171 out of the mounting groove 17 through the mating groove 15 to open the material discharge port 14. At this time, the spring 23 is compressed by force, the injection box 20 pushes the protective cover 19 and the injection needle to pierce the bottom of the capsule 5 and inject drinking water. After injecting the drinking water, the pressure inside the capsule 5 rises, and the aluminum foil film of the capsule 5 is pressed and expanded and can be pierced by a plurality of thimbles 13. The extracted coffee liquid can flow out to the material discharge port 14. After the extraction is completed, the electric slider 11 drives the extraction cylinder 12 to reset. At this time, under the action of the spring 23, the slider 171 resets to seal the material discharge port 14. After the extraction cylinder 12 resets, the electric gripper 8 cooperates with the lifting platform 6 and the rotating rod 7 to take out the used capsule 5 and release it into the trash can inside the machine case 1.

[0035] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the utility model.
