[0002] With the continuous progress of society, various coffee machines have emerged. The traditional components inside a coffee machine generally include a water tank, heating element, and water pump. For portability, various types of coffee, such as roasted and ground coffee and instant coffee, are packaged in a sealed coffee bag similar to a jelly bag. When using the machine, the coffee bag containing the coffee is placed inside the coffee machine, and then heated water is pumped into the chamber inside the coffee machine where the coffee bag is placed. The water flows through the raw material to be extracted, such as coffee, and the hot coffee flows from the water outlet of the coffee machine into the cup.

[0003] After use, the used coffee packet needs to be removed. Previously, the coffee machine required manually removing and discarding the packet from the chamber after each use, which was inconvenient. Furthermore, it was impossible to determine whether the machine had completely reset after each use. Utility Model Content

[0030] like Figures 1 to 8As shown, this utility model provides a top-packet unpacking structure for a coffee machine, including a front cover 1 and a rear cover 2, which are fixedly connected by two connecting posts 3. It also includes a housing 4, with both ends of the housing 4 fixedly connected to the connecting posts 3. Specifically, the housing 4 is provided with an extraction part 5, a packaging part 6, and a linkage part 7. The linkage part 7 includes a linkage rod structure 8 and a top-packet unpacking structure 9, and the linkage rod structure 8 and the top-packet unpacking structure 9 are respectively provided with mutually cooperating reset units.

[0031] When the packaging section 6 is opened, the coffee bag 25 falls into the packaging section 6. The linkage structure 8 rotates, causing the top bag release structure 9 to move towards the coffee bag 25. The reset unit causes the linkage structure 8 and the top bag release structure 9 to quickly reset. The top bag release structure 9 presses the coffee bag 25 and extracts the coffee. After extraction, the linkage structure 8 rotates in the opposite direction and pushes the top bag release structure 9 towards the coffee bag 25 until the coffee bag 25 falls off.

[0032] The linkage structure 8 includes a sliding cover 10 and a three-bar linkage unit that works in conjunction with the sliding cover 10. The top of the outer shell 4 is provided with a track 11 for the sliding cover 10 to slide horizontally. The three-bar linkage unit is hinged to the bottom of the sliding cover 10, and the side of the three-bar linkage unit is connected to the top pack unpacking structure 9. Specifically, the sliding cover 10 slides horizontally along the track 11 and drives the three-bar linkage unit to rotate. The three-bar linkage unit drives the top pack unpacking structure 9 to move horizontally along the connecting column 3.

[0033] The three-bar linkage unit includes a transmission rod 12, a linkage group 13, and a rotating link 14. One end of the transmission rod 12, one end of the linkage group 13, and one end of the rotating link 14 are connected in series by a pin 15. The other end of the transmission rod 12 is hinged to the bottom of the sliding cover 10. Specifically, the rotating link 14 is respectively located on both sides of the transmission rod 12. The end of the linkage group 13 near the pin 15 is arranged between the transmission rod 12 and the rotating link 14. The other end of the linkage group 13 is hinged to a fixing member 16. Both ends of the fixing member 16 are fixedly connected to the connecting column 3.

[0034] The reset unit includes a rotating hook 17 hinged to the end of the linkage group 13. The rotating hook 17 is located at the bottom of the linkage group 13 near the pin 15. A torsion spring 18 is wound around the connection between the rotating hook 17 and the linkage group 13. Specifically, the reset unit also includes a reset post 19 extending from the top packing unpacking structure 9 toward the linkage structure 8. The rotating hook 17 and the linkage group 13 are hinged together by a locking screw.

[0035] The rotating hook 17 has a hook 20 in a curved shape at the end away from the torsion spring 18. The hook 20 bends towards the linkage rod group 13. The reset column 19 has a column 21 that cooperates with the hook 20 at the end near the linkage rod structure 8. The column 21 is in a nearly cylindrical shape that contracts inward. Specifically, when the column 21 and the hook 20 are hooked together, the sliding cover 10 is moved further to move the column 21 and the hook 20 away from each other. Under the force of the torsion spring 18, the rotating hook 17 quickly resets the linkage rod structure 8 and the top pack unpacking structure 9.

[0036] The top-packing unloading structure 9 includes a first pushing plate 22, a second pushing plate 23, and a third pushing plate 24. The first pushing plate 22 is slidably connected to the connecting post 3 on both sides. The second pushing plate 23 is connected to the side of the first pushing plate 22 near the packaging section 6. The side of the second pushing plate 23 near the packaging section 6 is connected to the third pushing plate 24 for ejecting the coffee bag 25. A reset post 19 extends from the center of the third pushing plate 24 towards the linkage structure 8, passing through the first pushing plate 22 and the second pushing plate 23. Specifically, a spring 26 is sleeved on the reset post 19 to reset the third pushing plate 24 after unpacking. The reset post 19 also has a spring lock that abuts against the end of the spring 26, and the other end of the spring 26 abuts against the inner wall of the first pushing plate 22.

[0037] The end of the rotating connecting rod 14 away from the pin 15 is hinged to the first pushing plate 22. The linkage rod structure 8 drives the top bag removal structure 9 to slide along the connecting post 3 through the rotating connecting rod 14. After the back of the hook 20 contacts the end of the reset post 19 near the linkage rod structure 8, the sliding cover 10 continues to slide. The back of the hook 20 pushes the reset post 19 towards the packing part 6. The reset post 19 pushes the third pushing plate 24 to move towards the packing part 6 until the third pushing plate 24 pushes the coffee bag 25 placed in the packing part 6 out of the pack.

[0038] The second push plate 23 is connected to a receiving component 27 on the side near the packaging section 6. The bottom of the receiving component 27 extends toward the packaging section 6 and is provided with a receiving piece 28 for receiving the package. Specifically, the receiving piece 28 is inclined toward the inside of the packaging section 6.

[0039] The packaging section 6 is arranged between the extraction section 5 and the top packaging unpacking structure. The top of the packaging section 6 is an inlet 29 for dropping the coffee bag 25, and the bottom of the packaging section is a drop outlet 30 for dropping the coffee bag 25. Between the inlet 29 and the drop outlet 30 is a packaging cavity 31 for holding the coffee bag 25 and extracting it.

[0040] The working principle of this utility model is as follows:

[0041] Step 1: As Figure 1The image shows the original reset state, with the sliding cover 10 located at the leftmost position of the track 11. In this state, sliding the sliding cover 10 to the right along the track 11 causes the end of the transmission rod 12 connected to it to move synchronously to the right. Simultaneously, the end of the transmission rod 12 with the pin 15 moves upward and to the right. The end of the transmission rod 12 with the pin 15 moves, causing the linkage rod group 13 to rotate clockwise around the fixed member 16. The rotation of the linkage rod group 13 causes the rotating hook member 17 to rotate towards the reset post 19. At the same time, the end of the transmission rod 12 with the pin 15 moves, causing the rotating connecting rods 14 on both sides to rotate counterclockwise. The end of the rotating connecting rod 14 connected to the first push plate 22 causes the first push plate 22 to move to the right along the connecting post 3. The movement of the first push plate 22 to the right causes the second push plate 23, the third push plate 24, and the receiving member 27 to move synchronously to the right. Simultaneously, the reset post 19 moves towards the rotating hook member 17 until the sliding cover 10 is slid to the rightmost position of the track 11. Figure 2 As shown, the hook body 20 of the rotating hook body 17 is hooked onto the reset post 19.

[0042] Step 2: As Figure 2 The diagram shows the packaging state. At this point, the inlet 29 and the receiving piece 28 are vertically aligned, and the packaging cavity 31 is opened wide enough to accommodate the coffee bag 25. The user places the coffee bag 25 into the packaging cavity 31 through the inlet 29. The receiving piece 28 on the receiving component 27 holds the coffee bag 25. At this time, the sliding cover 10 slides to the left along the track 11, opposite to principle 1. The sliding cover 10 drives the end of the transmission rod 12 connected to it to move synchronously to the left. Simultaneously, the end of the transmission rod 12 with the pin 15 moves downwards and to the left. The end of the transmission rod 12 with the pin 15 moves, causing the linkage group 13 to rotate counterclockwise around the fixed part 16. The linkage group 13 rotates... The rotating hook 17 rotates away from the reset post 19. Simultaneously, one end of the transmission rod 12 with the pin 15 rotates, causing the rotating connecting rods 14 on both sides to rotate clockwise. The end of the rotating connecting rod 14 connected to the first push plate 22 moves the first push plate 22 to the left along the connecting post 3. The leftward movement of the first push plate 22 causes the second push plate 23, the third push plate 24, and the receiving component 27 to move synchronously to the left. At the same time, the reset post 19 moves away from the rotating hook 17. During this process, although the rotating hook 17 and the reset post 19 are gradually moving away from each other, the space between them is insufficient for the rotating hook 17 to rotate back to its original position. Figure 1 The original reset state, that is, when the linkage structure 8 and the top pack unpacking structure 9 are completely restored to the state described above. Figure 1 Before the initial reset state, the rotating hook 17 and the reset post 19 were still in a hooked state. The difference was that, due to the increasing horizontal distance between the rotating hook 17 and the reset post 19, the hooking position changed from... Figure 2 The conversion shown is as follows Figure 3 As shown, the hook 20 on the rotating hook body 17 is hooked onto the column 21 at the front end of the reset column 19.

[0043] Step 3: As Figure 3 The image shows the hook quickly resetting state, i.e., in the case of... Figure 3 Based on the state shown, continue to gently push the sliding cover 10 to the left along track 11. Since the rotating hook part 17 is hinged to the linkage rod group 13 through the torsion spring 18, under the action of the torsion spring 18, the rotating hook part 17 quickly returns to its original position. Figure 1 As shown in the original reset state, the rotating hook body 17 is perpendicular to the track 11 and pointing downwards. At the same time, the linkage structure 8 and the top pack unpacking structure 9 both quickly reset to the original state. Figure 1 In the original reset state shown, in this case, the force required for the reset of the other components in the linkage structure 8 and the top pack unpacking structure 9, except for the rotating hook body 17, is provided by the force and inertia generated by the torsion spring 18, rather than by the sliding cover 10 sliding to the left. Figure 1 The state shown can also be called the extraction state.

[0044] Step 4: As Figure 1 In the extraction state shown, the left side of the third push plate 24 presses against the coffee bag 25 in the packaging cavity 31, and the extraction unit 5 extracts the coffee bag 25 in the packaging cavity 31. The specific structure and working principle of the extraction unit 5 are technical means commonly used and easily thought of by those skilled in the art, so they will not be described in detail.

[0045] Step 5: After the extraction is completed, in the following way... Figure 1 Based on the above, slide the sliding cover 10 to the right along the track 11. Similar to principle 1, the sliding cover 10 drives the end of the transmission rod 12 connected to it to move synchronously to the right. Simultaneously, the end of the transmission rod 12 with the pin 15 moves upward and to the right. The end of the transmission rod 12 with the pin 15 moves, driving the linkage group 13 to rotate clockwise around the fixed part 16. The rotation of the linkage group 13 drives the rotating hook part 17 to rotate closer to the reset post 19. Simultaneously, the end of the transmission rod 12 with the pin 15 moves, driving the rotating connecting rods 14 on both sides to rotate counterclockwise. The end of the rotating connecting rod 14 connected to the first pushing disc 22 drives the first pushing disc 22 to move to the right along the connecting post 3. The rightward movement of the first pushing disc 22 drives the second pushing disc 23, the third pushing disc 24, and the receiving part 27 to move synchronously to the right. Simultaneously, the reset post 19 moves closer to the rotating hook part 17. During this process, the back of the hook 20 contacts the post 21. Continue sliding the sliding cover 10 to the right until the following occurs. Figure 4In the top-pack state shown, the hook 20 pushes the reset column 19 to the left through the column 21. Since the first push plate 22 and the second push plate 23 are moving to the right during this process, the hook 20 pushes the reset column 19 to the left, causing the reset column 19 to drive the third push plate 24 to move to the left in sync. The spring 26 is compressed, and the third push plate 24 and the second push plate 23 separate to create a gap until the third push plate 24 pushes the discarded coffee bag 25, which has finished extraction, out of the packaging cavity 31 through the bag-dropping port 30, completing the unpacking action.

[0046] Step 6: After unpacking, continue sliding the sliding cover 10 to the right along track 11. As the hook 20 continues to rotate counterclockwise, the pushing force between the hook 20 and the column 21 decreases. Under the compression force of the spring 26, the third pushing disc 24 and the reset column 19 move rapidly to the right, and the third pushing disc 24 re-fits with the second pushing disc 23 until they return to their original positions. Figure 2 In the packaging state shown, the sliding cover 10 slides to the rightmost side of the track 11, the hook 20 of the rotating hook body 17 engages with the reset post 19, and the packaging cavity 31 opens to a space sufficient to accommodate the coffee bag 25, preparing for the next user packaging and coffee extraction, repeating steps 2-6.

[0047] The advantages of this utility model are as follows: by sliding the sliding cover 10, the linkage rod structure 8 is driven to rotate, and the linkage rod structure 8 drives the top pack unloading structure 9 to slide. During the rotation of the linkage rod structure 8, the rotating hook body 17 and the reset column 19 are quickly reset under the action of the torsion spring 18. At the same time, the rotating hook body 17 and the reset column 19 cooperate to realize the top pack unloading. The operation is simple and the adjustment is convenient.
