Description

Technical Field

[0001] The utility model belongs to the technical field of coffee machines, and particularly relates to a capsule coffee machine. Background Art

[0002] The so-called capsule coffee machine is that the manufacturer pre-loads coffee powder into a plastic capsule similar in shape to jelly, and then fills it with nitrogen to keep fresh. When coffee is needed, the capsule is put into the capsule coffee machine, and the capsule coffee machine can simply, conveniently and quickly brew coffee. When using a traditional capsule coffee machine, it is usually necessary to manually hold the coffee cup, which increases the labor intensity of the user.

[0003] A patent with the publication number CN217447404U discloses an automatic coffee machine for preparing espresso, including a coffee machine body. A tray is slidably mounted on the surface of the body, and a through groove is formed on the surface of the body. A first screw rod and a second screw rod are rotatably arranged in the body along the vertical direction. Connecting seats are threadedly arranged on both the first screw rod and the second screw rod. The connecting seats pass through the through groove and are fixedly connected to the tray. A driven gear and a driving pulley are fixedly arranged on the first screw rod, a driven pulley is fixedly arranged on the second screw rod, and a synchronous belt is sleeved between the driving pulley and the driven pulley in a transmission manner. A motor is fixedly arranged inside the body, and a driving bevel gear is fixedly arranged on the output shaft of the motor. The driving bevel gear is meshed with a driven bevel gear for transmission.

[0004] In the above solution, the motor drives the driving bevel gear to rotate. The driving bevel gear drives the first screw rod to rotate through the driven bevel gear. The first screw rod drives the synchronous belt to rotate through the driving pulley. Thus, the second screw rod is driven to rotate through the driven pulley, and further the synchronous rotation of the first screw rod and the second screw rod is realized, and the rising movement of the tray and the coffee cup on the tray is completed. The whole process does not require manual lifting of the coffee cup, reducing the labor intensity of the user. Since the coffee cup is only placed in the middle of the tray and no fixing mechanism is provided. When the mass of the coffee cup is relatively light, affected by external factors, the coffee cup may shift during the rising process of the tray driving the coffee cup, resulting in the coffee cup deviating from the middle position of the tray. The liquid outlet cannot accurately align with the middle position of the coffee cup, so that when coffee is discharged from the liquid outlet, the coffee cup is knocked down, causing waste of coffee.

During the process of rotating the cover plate 10 to press down the coffee capsule 17 through the pressing block 18, the connecting pipe 21 will pierce the bottom of the coffee capsule 17, facilitating the transportation of the coffee powder in the coffee capsule 17 into the capsule coffee machine.

[0029] A through hole is formed in the cover plate 10. A bolt 9 is slidably arranged in the through hole. A fixing plate 8 is fixedly arranged on the support base 11. A threaded hole threaded with the bolt 9 is formed in the fixing plate 8. The bolt 9 passes through the through hole and is threadedly connected with the threaded hole. It is used to fix the cover plate 10 to prevent the second spring 19 from bouncing open the cover plate 10.

[0030] A sliding groove is formed at the top of the base 1. A lifting platform 2 is slidably arranged up and down in the sliding groove. A coffee cup is placed above the lifting platform 2 and the lifting platform 2 is located below the liquid outlet 7. When the lifting platform 2 is in the lowest position, the top surface of the lifting platform 2 is flush with the top surface of the base 1. When the lifting platform 2 is in the highest position, the liquid outlet 7 extends into the coffee cup.

[0031] A driving mechanism for driving the lifting platform 2 to slide up and down is arranged in the base 1.

[0032] The driving mechanism includes a motor 25. Two second connecting plates 26 are fixedly arranged at the bottom of the base 1. The two second connecting plates 26 are symmetric about the center of the lifting platform 2. First connecting plates 24 are fixedly arranged on the opposite surfaces of the two second connecting plates 26. The motor 25 is installed on one of the first connecting plates 24. The output shaft of the motor 25 is fixedly provided with a bidirectional screw rod 22. The end of the bidirectional screw rod 22 away from the motor 25 is rotatably connected with the other first connecting plate 24.

[0033] A first slider 23 is threadedly connected to each of the two threaded sections of the bidirectional screw 22, and bumps 30 are fixedly arranged at both ends of each first slider 23. Two guide blocks 27 are fixedly arranged between the two first connecting plates 24, and a first guide groove 31 that slidably cooperates with the bump 30 is formed in each guide block 27. The two first connecting plates 24 and the two guide blocks 27 together enclose a rectangular frame. The two first sliders 23 are both located within the rectangular frame enclosed by the first connecting plates 24 and the guide blocks 27, and each first slider 23 is in limit sliding cooperation with the two guide blocks 27 through the bump 30.

[0034] A connecting groove is formed at the bottom of the lifting platform 2, and two second sliders 29 are slidably arranged in the connecting groove. Bumps 30 are fixedly arranged at both ends of each second slider 29. Second guide grooves 32 that slidably cooperate with the bumps 30 are symmetrically formed on both inner walls of the connecting groove. One end of each second slider 29 is slidably connected to one of the second guide grooves 32, and the other end of each second slider 29 is slidably connected to the other second guide groove 32.

[0035] The two first sliders 23 and the two second sliders 29 correspond to each other one by one. Two X-shaped transmission members are symmetrically arranged in the connecting groove of the lifting platform 2. The transmission member is composed of two connecting rods 28 that are cross-arranged and rotatably connected. The part where the two connecting rods 28 in the same transmission member are in contact is rotatably connected through a rotating shaft. The two connecting rods 28 in the same transmission member both rotate in the same vertical plane. The end parts at the top of the two connecting rods 28 correspond to the two second sliders 29 one by one, and each second slider 29 is hinged to the top end part of the corresponding connecting rod 28. The end parts at the bottom of the two connecting rods 28 correspond to the two first sliders 23 one by one, and each first slider 23 is hinged to the bottom end part of the corresponding connecting rod 28.

[0036] Two clamping members are symmetrically arranged at the top of the lifting platform 2. First racks 3 are horizontally fixedly arranged at the ends of the two clamping members that are far away from each other. The clamping members and the first racks 3 are both slidably connected to the top of the lifting platform 2.

[0037] Two limiting blocks 15 are fixedly arranged on the lifting platform 2, and two second racks 6 are fixedly arranged vertically at the top of the base 1. The two limiting blocks 15 and the two second racks 6 correspond to each other one by one, and a first rack 3 is in limit sliding cooperation between each limiting block 15 and the corresponding second rack 6 for limiting the first rack 3.

[0038] Two sets of fixed seats are fixedly arranged at the top of the lifting table 2. Each set of fixed seats includes two connecting blocks 16, and the bottom of each connecting block 16 is fixedly connected to the top of the lifting table 2. A gear 5 is rotatably arranged between the two connecting blocks 16 in the same fixed seat. The two gears 5 correspond to the two second racks 6 one by one and also correspond to the two first racks 3 one by one. Each gear 5 meshes with the corresponding second rack 6 and also meshes with the corresponding first rack 3. This facilitates the mutual approach of the two clamping members during the upward sliding of the lifting table 2.

[0039] The clamping member includes a first spring 13. Push plates 4 are fixedly arranged at the opposite ends of the two first racks 3. A guide post 14 is slidably arranged on the push plate 4. One end of the guide post 14 is fixedly provided with a limit disc (not shown in the figure), and the other end of the guide post 14 slidably penetrates through the push plate 4 and is fixedly provided with a clamping plate 12. The first spring 13 is fixedly sleeved on the outer surface of the guide post 14. One end of the first spring 13 is fixedly connected to the push plate 4, and the other end of the first spring 13 is fixedly connected to the clamping plate 12. And the middle positions of the opposite ends of the two clamping plates 12 are recessed inward, which is convenient for clamping the coffee cup.

[0040] Working principle: In the initial state, the cover plate 10 is in a fully open state. When using this coffee machine, place the coffee capsule 17 in the coffee capsule 17 fixing chamber so that the bottom of the coffee capsule 17 contacts the top of the sliding rod 20.

[0041] Then flip and close the cover plate 10, and the cover plate 10 drives the pressing block 18 to rotate together. During the process of flipping the cover plate 10, the pressing block 18 will contact the surface of the coffee capsule 17 and drive the coffee capsule 17 to slide downward in the coffee capsule 17 fixing chamber after contact. The downward sliding of the coffee capsule 17 in the coffee capsule 17 fixing chamber will compress the second spring 19 downward through the sliding rod 20. During this process, the connecting pipe 21 will pierce the surface of the coffee capsule 17 and convey the coffee powder in the coffee capsule 17 into the Leyin coffee machine. After that, pass the bolt 9 through the through hole and thread it into the threaded hole on the fixing plate 8 to fix the cover plate 10.

[0042] When coffee needs to be received, place the coffee cup between the two clamping plates 12. Start the motor 25, and the output shaft of the motor 25 drives the bidirectional screw 22 to rotate. The rotation of the bidirectional screw 22 will drive the two first sliders 23 to approach each other along the central axis of the bidirectional screw 22 under the limit sliding fit of the convex block 30 and the first guide groove 31.

[0043] During the process of the two first sliders 23 approaching each other, they drive the two second sliders 29 to approach each other under the limit sliding fit of the convex block 30 and the second guide groove 32 through the connecting rod 28, thereby pushing the lifting table 2 to slide upward under the limit of the sliding groove. The upward sliding of the lifting table 2 will drive the coffee cup to move towards the direction close to the liquid outlet 7.

[0044] Moreover, during the upward sliding of the lifting table 2, the gear 5, the first rack 3, the limit block 15 and the clamping member will be driven to slide upward synchronously. Since the gear 5 meshes with the second rack 6, the gear 5 will rotate itself during the upward sliding process, thereby driving the two first racks 3 to approach each other under the limitation of the limit block 15 and the second rack 6.

[0045] The approaching of the two first racks 3 will push the two push plates 4 to approach each other. The approaching of the two push plates 4 will push the two clamping plates 12 to approach each other by squeezing the first spring 13, thereby clamping the coffee cup. This can prevent the coffee discharged from the liquid outlet 7 from knocking down the coffee cup and causing unnecessary waste. Moreover, by utilizing the elastic action of the first spring 13, the Leyin coffee machine can clamp coffee cups with different diameters, and has a wider range of use.
