Description

Technical Field

[0001] The present invention relates to the field of capsule coffee machines, and particularly to an extraction mechanism of a capsule coffee machine and a corresponding capsule coffee machine. Background Art

[0002] The so-called capsule coffee machine (hereinafter simply referred to as coffee machine) is a machine in which manufacturers pre-fill coffee powder into a plastic capsule similar in shape to jelly, and then fill it with nitrogen to preserve freshness, forming a coffee capsule (or simply referred to as a capsule). When coffee is needed, the capsule is placed into the coffee machine, and the coffee machine can simply, conveniently, and quickly brew coffee. Its usage process is roughly as follows: First, open the lid of the capsule inlet of the coffee machine, place the capsule into the coffee machine, close the lid, and then press the switch to start brewing coffee. During the brewing process, the outer membrane of the capsule will first be penetrated by a needle, and then the heated hot water will quickly enter the capsule under a certain pressure, and after extracting the coffee powder through the filter inside the capsule, it will flow into the coffee cup below, thus completing the brewing of coffee. After brewing coffee once, if you want to brew again, you can open the lid, put in a new capsule, and then start the brewing step again.

[0003] In order to improve the existing capsule coffee machines, the applicant applied for several patents related to capsule coffee machines in September 2019. However, during the subsequent R & D process, in order to further optimize the structure of the capsule coffee machine, the applicant improved many structures of the capsule coffee machine. For example, the applicant redesigned the capsule access mechanism and the lifting mechanism, and in order to cooperate with the newly designed lifting mechanism, the applicant specifically designed the extraction mechanism of this application, so that it can extract the capsules sent by the lifting mechanism, and after extraction, it can automatically release the capsule shell, making it fall automatically into the trash can along the corresponding channel. Summary of the Utility Model

[0004] The technical problem to be solved by the present invention is to provide a capsule extraction mechanism to cooperate with the lifting mechanism designed by the applicant for work, which can extract the capsules sent by the lifting mechanism, and after extraction, it can automatically release the capsule shell, making it fall automatically into the trash can along the corresponding channel; at the same time, based on this capsule extraction mechanism, the applicant also provides a corresponding capsule coffee machine.

[0005] To solve the above technical problem, in a first aspect, the present invention provides a capsule extraction mechanism, which includes:

[0006] A power component for providing power for horizontal reciprocating movement;

[0007] The capsule cup is used to hold a capsule, and the capsule cup can move in an arc around a rotation axis under the drive of the power component; wherein, the rotation axis is connected to one end of the capsule cup and is located above the path of the horizontal reciprocating movement of the power component; when the capsule cup moves in an arc, the extreme positions of the swing are respectively a horizontal state and a state with an angle not less than 90° with the horizontal state;

[0008] The extraction head is arranged at a position corresponding to when the capsule cup is in a horizontal state, and it includes a puncturing needle and a water injection port. The puncturing needle is a hollow structure and is used to puncture the outer membrane of the capsule during extraction. The water injection port is communicated with the puncturing needle, and the water injection port is used to be connected to a water path to inject water into the capsule for coffee extraction.

[0009] Furthermore, the capsule extraction mechanism further includes a fixing plate and a loading stopper;

[0010] The rotation axis is installed below the fixing plate through two ear plates;

[0011] The swing angle range of the capsule cup is α, 90° < α < 150°; a slot is opened in the middle of the end of the capsule cup connected to the rotation axis. The bottom of the slot has a plane A and a plane B. Plane B is located on the outer side of plane A, and the included angle between plane A and plane B is β, β = 180° - (α - 90°);

[0012] The loading stopper is installed on the rotation axis and is located in the slot of the capsule cup; a protruding clamping edge is provided on the front side of the loading stopper, and the clamping edge is used to stick to the surface of the edge of the capsule to limit the capsule. The rear side of the loading stopper has a plane C; between the clamping edge and plane C, the upper side of the loading stopper is plane D and the lower side is plane F; when plane C abuts against the fixing plate, the clamping edge is in a vertical state, and at this time, the loading stopper is at the extreme limit of downward flipping; when plane D abuts against the bottom surface of the fixing plate, the clamping edge is in a horizontal state, and at this time, the loading stopper is at the extreme limit of upward flipping;

[0013] When the capsule cup moves in an arc towards the side close to the extraction head, when the capsule cup moves to a vertical state, plane A of the capsule cup just contacts plane F of the loading stopper. When the capsule cup moves to a horizontal state, plane D of the loading stopper is also in a horizontal state; when the capsule cup moves in an arc towards the side away from the extraction head, when the angle of the capsule cup with the horizontal state is α - 90°, plane B of the capsule cup just contacts plane F of the loading stopper. When the angle of the capsule cup with the horizontal state is α, plane B of the capsule cup just contacts plane F of the loading stopper;

[0014] Furthermore, α = 125° and β = 145°.

[0015] Further, the capsule extraction mechanism further includes two guide plates, both of which are fixed below the fixed plate and are respectively located outside the left and right sides of the capsule cup. A guide groove A is provided on the inner wall of the guide plate;

[0016] A guide groove B is provided on the outer wall of each of the left and right sides of the capsule cup;

[0017] The output end of the power component is connected with two driving arms, which are respectively located between the two guide plates and the capsule cup. Guide shafts are provided on both driving arms, and both ends of the guide shafts are respectively inserted into the guide groove A and the guide groove B;

[0018] When the guide shaft moves along the guide groove A and the guide groove B, the capsule cup can be driven to make an arc movement around the rotation axis.

[0019] Further, the extraction head further includes an extraction seat, which is fixed on the fixed plate. A sealing gasket is provided below the extraction seat, and the arrangement position of the sealing gasket corresponds to the position when the capsule cup is in a horizontal state, so as to seal the periphery of the capsule during extraction; the water injection port is fixed above the extraction seat, and the puncture needle penetrates through the extraction seat and the sealing gasket and extends below the sealing gasket.

[0020] Further, the power component is an electric push rod.

[0021] Further, the shape of the inner cavity of the capsule cup is consistent with the outer contour of the capsule, so as to just accommodate the capsule therein, and a liquid outlet is further provided at the bottom of the capsule cup.

[0022] The working principle of the above technical solution is as follows:

[0023] Extraction:

[0024] In the initial state, both the capsule cup and the loading stopper are at the extreme positions of swinging downward. When the lifting mechanism of the capsule coffee machine sends the capsule to the topmost position, the capsule is in a vertical state and on the movement path of the capsule cup. At the same time, the edge at the top of the capsule is behind the catching edge of the loading stopper. After that, when the power component is activated to move forward, the capsule cup will perform an upward flipping arc movement along with the power component. During this process, when the capsule cup moves to the vertical state, it will "pick up" the capsule and move to the horizontal state. At the same time, when the capsule cup moves to the vertical state, the plane A of the capsule cup will contact the plane F of the loading stopper. Therefore, the subsequent movement of the capsule cup will drive the loading stopper to flip upward together. When the capsule moves below the extraction head along with the capsule cup, the needle of the extraction head will pierce the outer membrane of the capsule and penetrate into the capsule. After that, with the capsule in the horizontal state, high-pressure hot water can be injected through the water injection port of the extraction head to extract the coffee powder in the capsule, and then coffee liquid is brewed. The brewed coffee liquid will break through the bottom membrane of the capsule and then flow down from the liquid outlet at the bottom of the capsule cup.

[0025] After extraction, the capsule shell becomes waste, so it needs to be discarded. And this embodiment can realize the function of automatically releasing the waste capsule shell so that the capsule shell can fall into the trash can along the corresponding channel. The specific process is as follows.

[0026] After extraction:

[0027] After the extraction is completed, the power component is activated to move backward. At this time, the capsule cup will perform a downward flipping arc movement along with the power component. Since when the capsule cup moves to an angle of α - 90° with the horizontal state, the plane B of the capsule cup will contact the plane F of the loading stopper. Therefore, when the capsule cup continues to flip downward, the plane B will push against the plane F, so that the loading stopper will flip downward together. And there is a catching edge on the front side of the loading stopper (the catching edge is stuck to the surface of the capsule edge). Therefore, if the capsule adheres to the gasket due to the relatively high extraction pressure and does not rotate downward together with the capsule cup, the catching edge of the loading stopper can push the capsule downward to separate it from the gasket. When the loading stopper rotates downward by 90°, the plane D of the loading stopper will abut against the bottom surface of the fixed plate and stop rotating. At this time, the catching edge of the loading stopper is in a vertical state, getting ready for the next extraction. And the capsule will fall out of the capsule cup, then drop down and enter the corresponding discharging channel, and finally fall into the trash can along the discharging channel.

[0028] Advantages of the above technical solution: The above-provided capsule extraction mechanism can cooperate with the lifting mechanism designed by the applicant to work, can extract the capsules sent by the lifting mechanism, and can automatically release the waste capsule shells after extraction, enabling them to automatically fall into the trash can along the corresponding channels. That is, the present invention can automatically complete the entire process of extracting capsules and discarding waste capsule shells.

[0029] In a second aspect, the present invention further provides a capsule coffee machine, including a capsule extraction mechanism, which adopts the capsule extraction mechanism described above. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0046] Embodiment 1:

[0047] See Figures 1 - 12 , this embodiment provides a capsule extraction mechanism, which includes a power component 51, a capsule cup 52, and an extraction head 53.

[0048] The power component 51 is used to provide the power for horizontal reciprocating movement.

[0049] The capsule cup 52 is used to hold the capsule a. The capsule cup 52 can make an arc movement around the rotation shaft 54 under the drive of the power component 51; wherein, the rotation shaft 54 is connected to one end of the capsule cup 52 and is located above the path of the horizontal reciprocating movement of the power component 51; when the capsule cup 52 makes an arc movement, the extreme positions of the swing are respectively the horizontal state and the state with an angle not less than 90° with the horizontal state.

[0050] The extraction head 53 is arranged at a position corresponding to when the capsule cup 52 is in the horizontal state. It includes a needle 531 and a water injection port 532. The needle 531 is a hollow structure and is used to pierce the outer membrane of the capsule during extraction. The water injection port 532 is communicated with the needle 531, and the water injection port 532 is used to connect with the water path to inject water into the capsule to extract coffee.

[0051] More specifically:

[0052] The capsule extraction mechanism of this embodiment further includes a fixing plate 50 and a loading stopper 55.

[0053] The rotation shaft 54 is installed below the fixing plate 50 through two ear plates 56, as Figure 6 shown.

[0054] The swing angle range of the capsule cup 52 is α. Generally, 90° < α < 150°. In this embodiment, α = 125°, as Figure 5 shown. As Figure 5 and Figure 10 shown, a slot 521 is formed in the middle of one end of the capsule cup 52 connected to the rotating shaft 54. The bottom of the slot 521 has a flat surface A522 and a flat surface B523. The flat surface B523 is located on the outer side of the flat surface A522, and the included angle between the flat surface A522 and the flat surface B523 is β, and β = 180° - (α - 90°). That is, in this embodiment, β = 145°.

[0055] As Figure 5 and Figure 6 shown, the filling stopper 55 is installed on the rotating shaft 54 and is located in the slot 521 of the capsule cup 52. As Figure 5 shown, a protruding clamping edge 551 is provided on the front side of the filling stopper 55. The clamping edge 551 is used to stick to the surface of the edge of the capsule a to limit the capsule a. The rear side of the filling stopper 55 has a flat surface C552; between the clamping edge 551 and the flat surface C552, the upper side of the filling stopper 55 is a flat surface D553, and the lower side is a flat surface F554; when the flat surface C552 abuts against the fixed plate 50, the clamping edge 551 is in a vertical state. At this time, the filling stopper 55 is at the extreme limit of downward flipping, as Figure 4 shown; when the flat surface D553 is in a horizontal state, the clamping edge 551 is also in a horizontal state. At this time, the upper surface of the clamping edge 551 abuts against the corresponding component, and the filling stopper 55 is at the extreme limit of upward flipping, as Figure 9 and Figure 10 shown.

[0056] In addition, this embodiment also defines the following states:

[0057] When the capsule cup 52 moves in an arc towards the side close to the extraction head 53, when the capsule cup 52 moves to a vertical state, the flat surface A522 of the capsule cup 52 just contacts the flat surface F554 of the filling stopper 55; when the capsule cup 52 moves to a horizontal state, the flat surface D553 of the filling stopper 55 is also in a horizontal state. Refer to Figure 9 and Figure 10 . When the capsule cup 52 moves in an arc towards the side away from the extraction head 53, when the capsule cup 52 moves to an angle of α - 90° (i.e., 35°) with the horizontal state, the flat surface B523 of the capsule cup 52 just contacts the flat surface F554 of the filling stopper 55. Refer to Figure 12 ; when the capsule cup 52 moves to an angle of α with the horizontal state, the flat surface B523 of the capsule cup 52 just contacts the flat surface F554 of the filling stopper 55. Refer to Figure 4 andFigure 5 .

[0058] Preferably, as Figure 1 shown, the capsule extraction mechanism of this embodiment further includes two guide plates 57. Both of the two guide plates 57 are fixed below the fixing plate 50 and are respectively located outside the left and right sides of the capsule cup 52. A guide groove A571 is provided on the inner wall of the guide plate 57. As Figure 2 shown, a guide groove B524 is provided on each of the outer walls of the left and right sides of the capsule cup 52. Refer to Figure 2 , the output end of the power component 51 is connected with two driving arms 58. The two driving arms 58 are respectively located between the two guide plates 57 and the capsule cup 52. Guide shafts 581 are provided on both of the two driving arms 58. The two ends of the guide shaft 581 are respectively embedded in the guide groove A571 and the guide groove B524. When the guide shaft 581 moves along the guide groove A571 and the guide groove B524, it can drive the capsule cup 52 to make an arc movement around the rotation shaft 54. In order to ensure that the capsule cup 52 can be turned over smoothly, the guide groove A571 is a straight groove, but the guide groove B524 is not a straight groove, and its groove body trend is composed of two straight segments and an inclined segment. Refer to Figure 6 .

[0059] Preferably, refer to Figures 1 - 4 , the extraction head 53 further includes an extraction seat 533. The extraction seat 533 is fixed on the fixing plate 50. A sealing gasket 534 is provided below the extraction seat 533. The arrangement position of the sealing gasket 534 corresponds to the position when the capsule cup 52 is in a horizontal state, so as to seal the periphery of the capsule a during extraction and prevent liquid leakage. As Figure 8 and Figure 9 shown. As Figure 4 shown, the water injection port 532 is fixed above the extraction seat 533, and the puncture needle 531 penetrates through the extraction seat 533 and the sealing gasket 534 and extends below the sealing gasket 534.

[0060] Preferably, the power component 51 is an electric push rod.

[0061] Preferably, the shape of the inner cavity of the capsule cup 52 is the same as the outer contour shape of the capsule a, so as to just accommodate the capsule a therein. An outlet 525 is further provided at the bottom of the capsule cup 52. Refer to Figure 5 and Figure 9 .

[0062] The working principle of this embodiment is as follows:

[0063] Extraction:

[0064] In the initial state, as Figures 3 - 6As shown, both the capsule cup 52 and the loading stopper 55 are at the limit position of downward swing. When the lifting mechanism of the capsule coffee machine sends the capsule a to the topmost position, refer to Figure 4 and Figure 5 . At this time, the capsule a is in a vertical state and on the moving path of the capsule cup 52. Meanwhile, the edge at the top of the capsule a is behind the catching edge 551 of the loading stopper 55. Then, the power component 51 is started to move forward, and the capsule cup 52 will move along an upward turning arc with the power component 51. During this process, when the capsule cup 52 moves to the vertical state, it will "pick up" the capsule a and move to the horizontal state. At the same time, when the capsule cup 52 moves to the vertical state, the plane A522 of the capsule cup 52 will contact the plane F554 of the loading stopper 55. Therefore, the subsequent movement of the capsule cup 52 will drive the loading stopper 55 to turn upward together. When the capsule a moves to below the extraction head 53 with the capsule cup 52, the puncturing needle 531 of the extraction head 53 will pierce the outer membrane of the capsule a and penetrate into the capsule a. Then, when the capsule a is in the horizontal state (as shown in Figures 7 - 11 ), high-pressure hot water can be injected through the water injection port 532 of the extraction head 53 to extract the coffee powder in the capsule a, and then coffee liquid is brewed. The brewed coffee liquid will break through the bottom film of the capsule a and then flow down from the liquid outlet 525 at the bottom of the capsule cup 52.

[0065] After extraction, the capsule shell becomes waste, so it needs to be discarded. And the present invention can realize the function of automatically releasing the waste capsule shell so that the capsule shell can fall into the trash can along the corresponding channel. The specific process is as follows.

[0066] After extraction:

[0067] After completion of extraction, the power component 51 is started to move backward. At this time, the capsule cup 52 will move along a downward turning arc with the power component 51. Since when the capsule cup 52 moves to an angle of α - 90° (i.e., 35°) with the horizontal state, the plane B523 of the capsule cup 52 will contact the plane F554 of the loading stopper. Refer to Figure 12 . Therefore, when the capsule cup 52 continues to turn downward, the plane B523 will push against the plane F554, so that the loading stopper 55 turns downward together. The catching edge 551 is provided on the front side of the loading stopper 55 (the catching edge 551 is stuck to the surface of the edge of the capsule a. Refer to Figure 9 and Figure 10), so if the capsule a adheres to the gasket 534 due to the relatively high extraction pressure and does not rotate downward with the capsule cup 52, the clamping edge 551 of the loading block 55 can push the capsule a downward to disengage it from the gasket 534; when the loading block 55 rotates downward by 90°, the plane D553 of the loading block 55 will abut against the bottom surface of the fixed plate 50 and stop rotating. At this time, the clamping edge 551 of the loading block 55 is in a vertical state, preparing for the next extraction. The capsule a will then fall out of the capsule cup 52, then drop downward and enter the corresponding discharge channel, and finally fall into the trash can along the discharge channel.

[0068] It can be seen that the capsule extraction mechanism of this embodiment can cooperate with the lifting mechanism designed by the applicant to work. It can extract the capsule a sent by the lifting mechanism, and after extraction, it can automatically release the discarded capsule shell, enabling it to automatically fall into the trash can along the corresponding channel. That is, this embodiment can automatically complete the entire process of extracting the capsule and discarding the discarded capsule shell.
