[0030] Unless otherwise defined, all technical and scientific terms used in the present specification have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are merely for the purpose of describing specific embodiments and are not intended to limit the present application. The term “and / or” used in the present specification includes any and all combinations of one or more of the related listed items. In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0031] Please refer to Figure 1 and Figure 2 The extraction mechanism 1 includes a bracket 10, a brewing assembly 20, a power assembly 30, a baffle assembly 40, a powder bin assembly 50, and a scraper 60. The brewing assembly 20 is arranged in the bracket 10, and the brewing assembly 20 is used for brewing a beverage. The power assembly 30 is arranged on the bracket 10, the powder bin assembly 50 is movably arranged on the bracket 10, the powder bin assembly 50 is located below the brewing assembly 20,

[0032] The power assembly 30 is connected with the powder bin assembly 50, and the power assembly 30 is used to drive the powder bin assembly 50 to reciprocate along the L-shaped track relative to the support 10, so that the powder bin assembly 50 realizes horizontal translation and vertical translation.

[0033] When the powder bin assembly 50 needs to receive powder, the powder bin assembly 50 moves to the first position, at this time, the powder bin assembly 50 and the brewing assembly 20 are staggered in the vertical direction, so as to facilitate the powder bin assembly 50 to receive powder, after the powder bin assembly 50 completes the powder receiving, the powder bin assembly 50 horizontally translates to the position directly below the brewing assembly 20, that is, the intermediate position, and then vertically translates to the second position, the powder bin assembly 50 and the brewing assembly 20 are connected, at this time, the powder in the powder bin assembly 50 can be brewed. After the brewing is completed, the powder bin assembly 50 vertically translates downward to the intermediate position, the powder bin assembly 50 and the brewing assembly 20 are separated, and then the powder bin assembly 50 horizontally translates to the first position, the powder bin assembly 50 and the brewing assembly 20 are staggered in the vertical direction again, and the powder bin assembly 50 can perform the next powder receiving operation.

[0034] The baffle assembly 40 is arranged on the support 10, and the baffle assembly 40 is located below the powder bin assembly 50, and during the vertical downward movement of the powder bin assembly 50 after the brewing is completed, the baffle assembly 40 abuts against the powder bin assembly 50, so as to push the powder cake (powder residue) that completes the brewing in the powder bin assembly 50 out of the powder bin assembly 50. The scraper 60 is arranged on the support 10, and the scraper 60 is used to scrape away the powder cake pushed out of the powder bin assembly 50 during the horizontal translation of the powder bin assembly 50 from the intermediate position to the first position, so that the powder bin assembly 50 that returns to the first position is in an empty state, so as to prevent the previous powder cake from occupying the powder bin assembly 50 and affecting the next powder receiving of the powder bin assembly 50.

[0035] In order to facilitate the reader to understand the inventive concept of the present application, the following describes the entire brewing process:

[0036] The first position (as shown in FIG. 1) is a position where the powder bin assembly 50 receives powder, when the powder bin assembly 50 is located at the first position, the powder bin assembly 50 and the brewing assembly 20 are staggered in the vertical direction, so as to facilitate the powder bin assembly 50 to perform the powder receiving operation. Figure 9

[0037] The second position (as shown in FIG. 2) is a position where the powder bin assembly 50 and the brewing assembly 20 are connected, and the powder bin assembly 50 performs brewing. Figure 7 Figure 10 The intermediate position refers to a position where the powder bin assembly 50 is located directly below the brewing assembly 20, and the powder bin assembly 50 is separated from the brewing assembly 20 (as shown in FIG. 3).

[0038] Figure 8 Figure 11 ​​​​The intermediate position is also the position where the moving direction of the powder bin assembly 50 changes when the powder bin assembly 50 moves between the first position and the second position.

[0039] The brewing process of the beverage is as follows: Figure 9 The powder bin assembly 50 is initially located at the first position. When the powder, such as coffee powder, for brewing the beverage is put into the accommodating cavity 511 of the powder bin assembly 50, the power assembly 30 is started. Under the driving action of the power assembly 30, the powder bin assembly 50 moves horizontally from the first position to the intermediate position along the first direction X. Please refer to Figure 10 Then the powder bin assembly 50 is driven to move to the second position along the second direction Y. At this time, the powder bin assembly 50 is docked with the brewing assembly 20, and the baffle assembly 40 abuts against the end of the push rod 52 in the powder bin assembly 50 away from the brewing assembly 20. At this time, the powder in the powder bin assembly 50 can be brewed to form a beverage. After the brewing is completed, the power assembly 30 is reversely driven. Please refer to Figure 11 to make the powder bin assembly 50 move along the opposite direction of the second direction Y until the powder bin assembly 50 moves to the intermediate position and is separated from the brewing assembly 20. At this time, since the baffle assembly 40 abuts against the end of the push rod 52 in the powder bin assembly 50 away from the brewing assembly 20, the push rod 52 does not move downward, and the push rod 52 pushes the powder in the powder bin assembly 50 out of the accommodating cavity 511. After the powder bin assembly 50 moves to the intermediate position along the opposite direction of the second direction Y, under the continuous driving action of the power assembly 30, the powder bin assembly 50 moves along the opposite direction of the first direction X. When the powder bin assembly 50 moves along the opposite direction of the first direction X, the scraper 60 does not move in the first direction X, that is, the powder bin assembly 50 and the scraper 60 move relatively, and the scraper 60 scrapes the powder from the top of the push rod 52 during the movement of the powder bin assembly 50. When the powder bin assembly 50 moves to the first position along the opposite direction of the first direction X, the baffle assembly 40 and the push rod 52 are disengaged from the abutment, the push rod 52 is reset, the push rod 52 no longer occupies the accommodating cavity 511, and the accommodating cavity 511 is in an empty bin state. The accommodating cavity 511 is used for the next powder receiving operation.

[0040] It should be noted that the first direction X and the second direction Y are substantially perpendicular. The horizontal translation refers to the direction parallel to the bearing surface of the object when the extraction mechanism 1 is placed on the bearing surface of the object. The vertical translation refers to the direction perpendicular to the bearing surface of the object when the extraction mechanism 1 is placed on the bearing surface of the object. For example, when the extraction mechanism 1 is placed on the ground, the first direction X is substantially parallel to the ground, and the second direction Y is substantially perpendicular to the ground.

[0041] It can be understood that, in some embodiments, when the powder bin assembly 50 moves from the first position to the intermediate position, it can be horizontal translation along the first direction X, or it can be inclined upward movement. Of course, when the powder bin assembly 50 resets from the intermediate position to the first position, it can be horizontal translation along the first direction X, or it can be inclined downward movement.

[0042] For the above-mentioned support 10, please refer to Figure 2 and Figure 3 The support 10 includes a first side plate 11 and a second side plate 12. The first side plate 11 and the second side plate 12 are arranged substantially in parallel, and the first side plate 11 and the second side plate 12 are fixedly connected. The brewing assembly 20, the baffle assembly 40 and the powder bin assembly 50 are arranged between the first side plate 11 and the second side plate 12. The power assembly 30 is arranged outside the first side plate 11 or the second side plate 12, so as to avoid occupying the space between the first side plate 11 and the second side plate 12.

[0043] The first side plate 11 is provided with a first track groove 111, and the first track groove 111 includes a first section 1111 and a second section 1112 in communication. The first section 1111 extends along the first direction X, and the second section 1112 extends along the second direction Y. An inflection point is formed at the joint of the first section 1111 and the second section 1112, so that the first track groove 111 is substantially L-shaped. Please refer to Figure 1 The powder bin assembly 50 is provided with a first fulcrum 561 protruding, which is inserted into the first track groove 111. Under the driving action of the power assembly 30, the powder bin assembly 50 moves along the first track groove 111.

[0044] In order to make the left and right sides of the powder bin assembly 50 move more stably, the second side plate 12 is provided with a second track groove 121, and the second track groove 121 includes a third section 1211 and a fourth section 1212 in communication. The third section 1211 extends along the first direction X, and the fourth section 1212 extends along the second direction Y. An inflection point is formed at the joint of the third section 1211 and the fourth section 1212, so that the second track groove 121 is substantially L-shaped. Please refer to Figure 2 The powder bin assembly 50 is provided with a second fulcrum 562, wherein the first fulcrum 561 and the second fulcrum 562 are respectively located on opposite sides of the powder bin assembly 50. The second fulcrum 562 is inserted into the second track groove 121. Under the driving action of the power assembly 30, the powder bin assembly 50 moves along the second track groove 121.

[0045] In order to prevent the powder bin assembly 50 from rotating during movement, at least two fulcrums on the same side of the powder bin assembly 50 can effectively increase the stability of the powder bin assembly 50. Please refer to Figure 1That is, the powder bin assembly 50 is further provided with a third fulcrum 563, and the first fulcrum 561 and the third fulcrum 563 are located on the same side of the powder bin assembly 50. Correspondingly, the first side plate 11 is further provided with a third trajectory groove 112, and the third trajectory groove 112 includes a fifth segment 1121 and a sixth segment 1122 in communication, wherein the fifth segment 1121 extends along the first direction X, and the sixth segment 1122 extends along the second direction Y. An inflection point is formed at the intersection of the fifth segment 1121 and the sixth segment 1122, so that the third trajectory groove 112 is also approximately L-shaped, and the third fulcrum 563 is inserted into the third trajectory groove 112.

[0046] In some embodiments, referring to Figure 2 , the powder bin assembly 50 is further provided with a fourth fulcrum 564, and the second fulcrum 562 and the fourth fulcrum 564 are located on the same side of the powder bin assembly 50. Correspondingly, the second side plate 12 is further provided with a fourth trajectory groove 122, and the fourth trajectory groove 122 includes a seventh segment 1221 and an eighth segment 1222 in communication, wherein the seventh segment 1221 extends along the first direction X, and the eighth segment 1222 extends along the second direction Y. An inflection point is formed at the intersection of the seventh segment 1221 and the eighth segment 1222, so that the fourth trajectory groove 122 is also approximately L-shaped, and the fourth fulcrum 564 is inserted into the third trajectory groove 112.

[0047] In some embodiments, the two L-shaped trajectory grooves on the first side plate 11 and the second side plate 12 are arranged to have an overlapping part, which can effectively reduce the volume of the first side plate 11 and the second side plate 12, thereby reducing the overall volume of the extraction mechanism 1 and meeting the design requirements of device miniaturization.

[0048] As an example, referring to Figure 3 , the first segment 1111 intersects and communicates with the sixth segment 1122, so that the third fulcrum 563 can cross the first segment 1111. During the movement of the powder bin assembly 50, when the first fulcrum 561 moves to the communication position of the first segment 1111 and the sixth segment 1122, the third fulcrum 563 is still in the fifth segment 1121 at this time, that is, the powder bin assembly 50 can only continue to move along the first direction X and cannot move along the second direction Y. Only when the first fulcrum 561 moves to the intersection of the first segment 1111 and the second segment 1112, and the third fulcrum 563 moves to the intersection of the fifth segment 1121 and the sixth segment 1122, can the powder bin assembly 50 move along the second direction Y. That is, the partial overlapping arrangement of the first trajectory groove 111 and the third trajectory groove 112 can effectively reduce the volume of the first side plate 11 and will not affect the movement of the powder bin assembly 50.

[0049] In other embodiments, the depth of the first trajectory groove 111 and the depth of the third trajectory groove 112 are different along the thickness direction of the first side plate 11, which can solve the problem of the affected movement of the first fulcrum 561 and the third fulcrum 563.

[0050] Similarly, please refer to Figure 3 , the third segment 1211 intersects and communicates with the eighth segment 1222, so that the fourth fulcrum 564 can cross the third segment 1211. The movement process of the second fulcrum 562 and the fourth fulcrum 564 of the powder bin assembly 50 can refer to the analysis of the first fulcrum 561 and the third fulcrum 563 described above, which will not be repeated here.

[0051] In some embodiments, in order to increase the smoothness of the movement of the first fulcrum 561, the second fulcrum 562, the third fulcrum 563 and the fourth fulcrum 564 in the corresponding track groove, the above four fulcrums can be equipped with pulleys or bearings, so that the movement between the four fulcrums and the first side plate 11 and the second side plate 12 changes from relative sliding to relative rolling, thereby reducing the friction of the powder bin assembly 50 when moving on the first side plate 11 and the second side plate 12.

[0052] In some embodiments, please continue to refer to Figure 3 , the bracket 10 further comprises a bottom plate 13, which is arranged at the bottom of the first side plate 11 and the second side plate 12, and one end of the bottom plate 13 is connected with the first side plate 11, and the other end of the bottom plate 13 is connected with the second side plate 12. The first side plate 11 and the second side plate 12 connected by the bottom plate 13 can enhance the strength and rigidity of the bracket 10, and improve the stability of the bracket 10.

[0053] For the above-mentioned brewing assembly 20, please refer to Figure 4 and Figure 8 , the brewing assembly 20 is located above the powder bin assembly 50, and the brewing assembly 20 comprises a brewing connector 21 and a filter 22. The brewing connector 21 is arranged between the first side plate 11 and the second side plate 12, and the brewing connector 21 communicates with the pipeline outside the world. The brewing connector 21 is used to deliver the brewed beverage to the output beverage end of the extraction mechanism 1. The filter 22 is arranged at the end of the brewing connector 21 close to the bottom plate 13. When the brewing assembly 20 is docked with the powder bin assembly 50 and brewing, the filter 22 is used to block the powder in the powder bin assembly 50 which is still in solid state, to prevent the solid powder from entering the brewing connector 21 during brewing, and to block the brewing connector 21. At the same time, it also avoids the influence of a large amount of solid powder in the beverage on the taste.

[0054] In some embodiments, please refer to Figure 4 , the brewing assembly 20 further comprises a fourth sealing member 23, which is arranged on the outer periphery of the brewing connector 21, as shown in Figure 10 , when the brewing connector 21 is inserted into the inside of the powder bin assembly 50, the fourth sealing member 23 is used to seal the gap between the brewing connector 21 and the powder bin assembly 50, to avoid leakage of the brewing liquid.

[0055] For the power assembly 30 described above, please refer to Figure 1 The power assembly 30 includes a motor 31 and a linkage component (not labeled), the motor 31 is arranged outside the first side plate 11 or the second side plate 12, avoiding occupying the space between the first side plate 11 and the second side plate 12. The linkage component is located between the first side plate 11 and the second side plate 12, and is connected with the motor 31 and the powder bin assembly 50 respectively, so that the motor 31 can drive the powder bin assembly 50 to make L-shaped trajectory reciprocating motion along the first trajectory slot 111 and the second trajectory slot 121.

[0056] In some embodiments, the linkage component includes a first linkage 32 and a second linkage 33, the first end of the first linkage 32 is connected with the output shaft of the motor 31, and the motor 31 drives the first linkage 32 to rotate. The first end of the second linkage 33 is rotationally connected with the second end of the first linkage 32, and the second end of the second linkage 33 is rotationally connected with the powder bin assembly 50. When the first linkage 32 rotates, the first linkage 32 drives the second linkage 33 to move, under the guidance of the L-shaped trajectory slot (the first trajectory slot 111 and the second trajectory slot 121) of the support 10, so that the powder bin assembly 50 makes L-shaped trajectory reciprocating motion. When the motor 31 rotates forward, the powder bin assembly 50 moves from the first position to the second position through the intermediate position; when the motor 31 reverses, the powder bin assembly 50 moves from the second position to the first position through the intermediate position.

[0057] It is worth noting that in the process of making L-shaped trajectory reciprocating motion relative to the support 10, the powder bin assembly 50 always keeps translational motion relative to the support 10, and the bin opening of the powder bin assembly 50 always keeps facing upward. In the traditional structure, the powder bin assembly 50 makes circular arc swing arm motion relative to the support 10, that is, the powder bin assembly 50 has an inclined posture, and the bin opening of the powder bin assembly 50 does not keep facing upward, which easily leads to powder spilling out during the movement of the powder bin assembly 50. By setting the powder bin assembly 50 to make L-shaped translational motion, the problem of powder spilling out during the movement of the powder bin assembly 50 can be effectively solved.

[0058] For the baffle assembly 40 described above, please refer to Figure 1 and Figure 2The baffle assembly 40 is movably arranged on the bottom plate 13. The bottom plate 13 is provided with an avoiding slot 131 extending along the first direction X. The baffle assembly 40 covers the avoiding slot 131. During the movement of the powder bin assembly 50 from the first position to the intermediate position, the push rod 52 in the powder bin assembly 50 moves along the avoiding slot 131. The push rod 52 in the powder bin assembly 50 abuts against the sidewall of the baffle assembly 40 to push the baffle assembly 40 away from the avoiding slot 131. During the upward movement of the powder bin assembly 50 from the intermediate position to the second position, the push rod 52 in the powder bin assembly 50 is separated from the sidewall of the baffle assembly 40. The baffle assembly 40 is reset to cover the avoiding slot 131 again. The baffle assembly 40 is located directly below the push rod 52. During the movement of the powder bin assembly 50 from the second position to the intermediate position, the baffle assembly 40 abuts against the end of the push rod 52 in the powder bin assembly 50 away from the brewing assembly 20 to prevent the push rod 52 from falling. During the movement of the powder bin assembly 50 from the intermediate position to the first position, the end of the push rod 52 in the powder bin assembly 50 away from the brewing assembly 20 slides off the baffle assembly 40. The push rod 52 is reset.

[0059] As an example, the baffle assembly 40 includes a sliding plate 41 and a first elastic member 42. The sliding plate 41 is movably arranged on the bottom plate 13 along the third direction Z. One end of the first elastic member 42 is connected to the sliding plate 41. The other end of the first elastic member 42 is connected to the bottom plate 13 or the first side plate 11. The sliding plate 41 has a blocking position and an avoiding position relative to the bottom plate 13. When the sliding plate 41 is in the blocking position, the sliding plate 41 covers the avoiding slot 131 on the bottom plate 13. When the sliding plate 41 is in the avoiding position, the sliding plate 41 opens the avoiding slot 131 of the bottom plate 13. The first elastic member 42 provides elastic force to the sliding plate 41 to drive the sliding plate 41 to move to the blocking position and keep the sliding plate 41 at the blocking position.

[0060] As an example, the first elastic member 42 is a spring. The third direction Z is perpendicular to the plane in which the first direction X and the second direction Y lie. Of course, in other embodiments, the sliding plate 41 can reciprocate relative to the bottom plate 13 in the first direction X to open or cover the avoiding slot 131 on the bottom plate 13.

[0061] In some embodiments, the bottom plate 13 is provided with a first guide portion. The sliding plate 41 is provided with a second guide portion. The first guide portion and the second guide portion are connected to guide the sliding plate 41 to switch between the blocking position and the avoiding position along the third direction Z.

[0062] As an example, the first guide portion includes a first fixed member 132. The second guide portion is a sliding groove 411. The first fixed member 132 is fixed to the bottom plate 13. The first fixed member 132 is inserted into the sliding groove 411. Under the guidance of the sliding groove 411, the sliding plate 41 can slide relative to the first fixed member 132.

[0063] In other examples, the first guide portion can be a rail, and the second guide portion can be a protrusion that cooperates with the rail, the protrusion being inserted into the rail so that the sliding plate 41 slides relative to the base plate 13 in the third direction Z.

[0064] In some embodiments, referring to Figure 1 , the sliding plate 41 is provided with a transition portion 412 at an end of the sliding plate 41 close to the notch of the avoidance slot 131, i.e., the end of the sliding plate 41 close to the first position of the powder bin assembly 50 is provided with the transition portion 412, the transition portion 412 is used to abut against the powder bin assembly 50, so that when the powder bin assembly 50 moves from the first position to the intermediate position, the powder bin assembly 50 first abuts against the transition portion 412, so as to facilitate the movement of the sliding plate 41 to the avoidance position.

[0065] For the above-mentioned powder bin assembly 50, referring to Figure 5 and Figure 6 , the powder bin assembly 50 includes a powder bin cup 51 and a push rod 52, the powder bin cup 51 is connected with the second end of the second connecting rod 33, the powder bin cup 51 is movably arranged between the first side plate 11 and the second side plate 12, and the powder bin cup 51 is used to store the powder to be brewed. The push rod 52 is partially arranged inside the powder bin cup 51, and a part of the push rod 52 penetrates out of the powder bin cup 51 from the bottom or the side of the powder bin cup 51, and the push rod 52 can reciprocate in the second direction Y inside the powder bin cup 51 to push the brewed powder cake out of the powder bin cup 51 and reset the push rod 52.

[0066] When the powder bin assembly 50 moves from the first position to the intermediate position, the push rod 52 abuts against the side wall of the baffle assembly 40 and pushes the baffle assembly 40 to move, when the powder bin assembly 50 reaches the second position, the baffle assembly 40 is located below the end of the push rod 52 away from the brewing assembly 20, and the baffle assembly 40 resets, when the powder bin cup 51 moves from the second position to the intermediate position, the baffle assembly 40 abuts against the end of the push rod 52 away from the brewing assembly 20, and the baffle assembly 40 does not allow the push rod 52 to move downward,

[0067] The push rod 52 pushes the powder cake in the powder bin cup 51 out.

[0068] As an example, the powder bin cup 51 is provided with a containing cavity 511, and the top of the powder bin cup 51 is provided with a bin opening communicating with the containing cavity 511, the containing cavity 511 is used to store the powder to be brewed. The push rod 52 includes a rod body 521 and a top plate 522, the top plate 522 is arranged in the containing cavity 511, the first end of the rod body 521 is connected with the top plate 522, and the second end of the rod body 521 penetrates out of the bottom of the powder bin cup 51. The rod body 521 can move relative to the powder bin cup 51, so as to push the top plate 522 to move in the containing cavity 511.

[0069] When the power assembly 30 drives the powder hopper cup 51 to move from the first position to the second position, the rod 521 in the push rod 52 first abuts against the transition part 412 of the sliding plate 41. As the powder hopper cup 51 continues to move, the rod 521 pushes the sliding plate 41 in the baffle assembly 40 to move towards the avoidance position. When the powder hopper assembly 50 moves to the second position, the second end of the rod 521 does not abut against the sliding plate 41 in the first direction X or the third direction Z. Instead, the second end of the rod 521 does not abut against the sliding plate 41 in the second direction Y, or they just abut against each other. Figure 7 As shown, under the action of the first elastic member 42, the sliding plate 41 moves from the avoidance position to the blocking position; when the powder container assembly 50 moves from the second position to the first position, the sliding plate 41 in the baffle assembly 40 abuts against the second end of the rod 521 in the second direction Y. The rod 521 is stationary relative to the sliding plate 41. As the powder container cup 51 continues to move downward, the rod 521 drives the top plate 522 to move in the receiving cavity 511, thereby pushing the powder compact out of the receiving cavity 511, as shown. Figure 8 As shown.

[0070] In some embodiments, please refer to Figure 6 The diameter of the top plate 522 is equal to the inner diameter of the receiving cavity 511 of the powder hopper cup 51, that is, the push rod 52 and the powder hopper cup 51 form a piston structure.

[0071] In some embodiments, please refer to Figure 5 and Figure 6 The powder container assembly 50 also includes a second elastic element 53, which is located outside the powder container cup 51. The second elastic element 53 is sleeved on the rod body 521, and its two ends respectively abut against the second end of the rod body 521 and the bottom of the powder container cup 51. The second elastic element 53 provides elastic force so that the rod body 521 drives the top plate 522 to move towards the bottom of the receiving cavity 511. As an example, the second elastic element 53 is a spring.

[0072] In some embodiments, please refer to Figure 5 and Figure 6 The powder container assembly 50 also includes a first sealing element 54, which is disposed at the bottom of the powder container cup 51. The first sealing element 54 abuts against the rod body 521, thereby sealing the gap between the rod body 521 and the powder container cup 51 and preventing the liquid in the receiving cavity 511 from flowing out from the gap between the powder container cup 51 and the rod body 521 during the brewing process.

[0073] In some embodiments, please refer to Figure 5 and Figure 6The powder bin assembly 50 further comprises a third elastic member 55 located on one side of the top plate 522 close to the cavity bottom of the accommodating cavity 511. The first end of the third elastic member 55 is connected with the powder bin cup 51, and the second end opposite to the first end is in abutment with the top plate 522. The third elastic member 55 is configured to provide elastic force to move the top plate 522 towards the bin opening, so that after the powder bin assembly 50 is docked with the brewing assembly 20, the top plate 522 can always press the powder between the top plate 522 and the brewing assembly 20 under the elastic force of the third elastic member 55, thereby facilitating the hot water of high temperature and high pressure to extract the pressed powder.

[0074] As an example, after the powder bin assembly 50 is docked with the brewing assembly 20, the brewing connector 21 enters the accommodating cavity 511 of the powder bin cup 51, and the relative position between the brewing connector 21 and the powder bin cup 51 is fixed. The third elastic member 55 is configured to adjust the distance between the top plate 522 and the filter 22, thereby changing the space between the top plate 522 and the filter 22. Specifically, when the powder is more, the distance between the top plate 522 and the filter 22 is larger, and when the powder is less, the distance between the top plate 522 and the filter 22 is smaller. However, no matter how much the amount of powder is, the top plate 522 can always press the powder between the filter 22 under the action of the third elastic member 55, i.e., the top plate 522 provides pressure to the powder to press the powder, thereby achieving extraction. As an example, the accommodating cavity 511 can accommodate 5-20 grams of coffee powder.

[0075] It can be understood that the powder, such as coffee powder, needs to be compacted during the brewing process to complete the extraction. If the third elastic member 55 is not provided, the distance between the top plate 522 and the filter 22 is constant after the powder bin assembly 50 is docked with the brewing assembly 20. When a small amount of powder is between the top plate 522 and the filter 22, the top plate 522 cannot compact the powder, and the powder is in a loose state. At this time, the hot water is only “washed” through the powder, but not extracted, which greatly reduces the taste of the beverage. By providing the third elastic member 55, the distance between the top plate 522 and the filter 22 can be adjusted, so that when different amounts of powder are added, the top plate 522 can always compact the powder, thereby facilitating the hot water of high temperature and high pressure to extract the compacted powder.

[0076] In some embodiments, referring to Figure 5 and Figure 6 , the powder bin assembly 50 further comprises a mounting frame 56, the powder bin cup 51 is sleeved in the interior of the mounting frame 56, and the second end of the second connecting rod 33 is connected with the mounting frame 56. The second connecting rod 33 drives the mounting frame 56 and the powder bin cup 51 to move synchronously. One side of the mounting frame 56 is provided with the first fulcrum 561 and the third fulcrum 563 as described above, as Figure 1As shown, the other side of the mounting frame 56 is provided with the second fulcrum 562 and the fourth fulcrum 564 (as shown in Figure 2 ).

[0077] For the scraper 60, please refer to Figure 3 , the scraper 60 is provided with a first protrusion 61, the first side plate 11 and / or the second side plate 12 of the bracket 10 is provided with a first track slot 113 along the second direction Y, the first protrusion 61 is inserted into the first track slot 113, and the first protrusion 61 reciprocates in the first track slot 113, so that the scraper 60 can reciprocate along the second direction Y relative to the first side plate 11 and the second side plate 12, but the scraper 60 is not allowed to move along the first direction X.

[0078] In some embodiments, please refer to Figure 3 , the side of the mounting frame 56 in the powder bin assembly 50 is provided with a second track slot 565 along the first direction X, the scraper 60 is provided with a second protrusion 62, the second protrusion 62 is inserted into the second track slot 565, and the second protrusion 62 reciprocates in the second track slot 565, so as to realize the synchronous movement of the scraper 60 and the powder bin assembly 50 along the second direction Y, and allow the powder bin assembly 50 to reciprocate along the first direction X relative to the scraper 60.

[0079] During the movement of the mounting frame 56 and the powder bin cup 51 from the first position to the intermediate position, the second protrusion 62 slides in the second track slot 565, at this time, since the rod body 521 pushes the sliding plate 41 to move to the avoiding position, the rod body 521 can move in the avoiding slot 131, so the top plate 522 does not push the powder in the containing cavity 511 out, when the mounting frame 56 and the powder bin cup 51 are located at the intermediate position, the scraper 60 is located outside the edge of the bin opening of the powder bin cup 51 (as shown in Figure 8 ), and then during the movement of the mounting frame 56 and the powder bin cup 51 from the intermediate position to the second position, the first protrusion 61 slides in the first track slot 113, so that the scraper 60 and the powder bin assembly 50 move together along the second direction Y to the second position (as shown in Figure 7 ).

[0080] After the brewing is completed, please refer to Figure 8 , the scraper 60 and the powder bin assembly 50 move in the reverse direction along the second direction Y, that is, downward, since the second end of the rod body 521 abuts against the sliding plate 41, with the continuous movement of the mounting frame 56 and the powder bin cup 51, the rod body 521 pushes the top plate 522 to gradually push the powder cake in the containing cavity 511 out, until the powder bin cup 51 is located at the intermediate position, the scraper 60 is still outside the edge of the bin opening. During the movement of the mounting frame 56 and the powder bin cup 51 from the intermediate position to the first position, the powder bin cup 51 moves relative to the scraper 60, the scraper 60 scrapes the powder cake pushed out by the top plate 522 away, until the mounting frame 56 and the powder bin cup 51 are located at the first position (asFigure 9 At this time, the second end of the rod body 521 does not abut against the sliding plate 41 in the second direction Y, and under the action of the second elastic member 53, the rod body 521 and the top plate 522 move downward, and the space of the accommodating cavity 511 is restored, so as to facilitate the next powder feeding.

[0081] In the present application, the movement track of the powder bin assembly 50 is set as an L-shaped track. On the one hand, the powder bin assembly 50 can always keep the bin opening facing upward, so as to prevent the powder from spilling out during the movement of the powder bin assembly 50. On the other hand, the L-shaped movement track has a vertical movement process, i.e., the movement process from the second position to the middle position. During this process, the powder cake in the accommodating cavity 511 can be pushed out by the push rod 52 through the cooperation and abutment with the baffle assembly 40 (as shown in Figure 8 Furthermore, the L-shaped movement track has a horizontal movement process, i.e., the movement process from the middle position to the first position (from Figure 8 to the state shown in Figure 9 During this process, the powder cake pushed out by the top plate 522 can be scraped off by the scraper 60. Through the above structure, the powder bin assembly 50 can clean the powder cake during the process of returning to the first position after the brewing is completed, which greatly improves the cleaning efficiency.

[0082] In some embodiments, referring to Figure 5 The extraction mechanism 1 further comprises a guide plate 70 connected to the mounting frame 56 in the powder bin assembly 50 or the side of the powder bin cup 51 away from the first position. The guide plate 70 moves synchronously with the powder bin assembly 50, and is used to guide the powder cake scraped off by the scraper 60 to the outside, so as to avoid the powder cake from being scattered in the interior of the extraction mechanism 1 after being scraped off by the scraper 60. In some embodiments, the guide plate 70 is provided with a blocking strip 71 on both sides, which is used to prevent the powder cake from being scattered in the interior of the extraction mechanism 1 during the movement process. It can be understood that the guide plate 70 and the mounting frame 56 can be independent parts spliced to form a whole, or the guide plate 70 and the mounting frame 56 can be integrally formed.

[0083] In some embodiments, the extraction assembly further comprises a liquid path assembly, which is used to provide high-temperature and high-pressure hot water for the powder bin assembly 50 and the brewing assembly 20 to brew the beverage. Referring to Figure 1The liquid path assembly includes a first liquid path component 81 and a second liquid path component 82. The first liquid path component 81 is arranged on the support 10, and the second liquid path component 82 is arranged on the powder bin assembly 50 and moves synchronously with the powder bin assembly 50. When the powder bin assembly 50 is in the second position, the first liquid path component 81 is connected to and in fluid communication with the second liquid path component 82, and at this time, hot water enters the containing cavity 511 of the powder bin assembly 50 through the first liquid path component 81 and the second liquid path component 82. When the powder bin assembly 50 is not in the second position, the first liquid path component 81 is separated from the second liquid path component 82, and the second liquid path component 82 is in communication with the outside air. The second liquid path component 82 is used to enable the powder bin assembly 50 to realize air intake or air exhaust, so as to avoid the negative pressure state in the containing cavity 511 and affect the docking or separation of the powder bin assembly 50 and the brewing assembly 20.

[0084] As an example, please refer to Figure 12 The first liquid path component 81 includes a first connector 811 and a second sealing member 812. The first connector 811 is fixed to the first side plate 11 or the second side plate 12 and is used to communicate with the external liquid supply pipeline. The second sealing member 812 is sleeved on the first connector 811 and is used to seal the gap between the first connector 811 and the second liquid path component 82 after the two components are docked, so as to avoid liquid leakage between the two components.

[0085] The first connector 811 is provided with a first liquid outlet 8111 for the liquid in the first connector 811 to flow out. The first liquid path component 81 further includes a third sealing member 813, which is sleeved on the first connector 811, and the second sealing member 812 and the third sealing member 813 are respectively located on the two sides of the first liquid outlet 8111 in the axial direction. The third sealing member 813 is used to seal the gap between the first connector 811 and the second liquid path component 82.

[0086] Please refer to Figure 13 The second liquid path component 82 includes a second connector 821, which is fixedly arranged on the outer wall of the powder bin cup 51 or the mounting bracket 56. Please refer to Figure 13 The second connector 821 is provided with a plug-in cavity 8211 and a connecting channel 8212, wherein the connecting channel 8212 fluidly connects the plug-in cavity 8211 and the containing cavity 511 inside the powder bin assembly 50. The plug-in cavity 8211 is used for plug-in of the first connector 811. When the first connector 811 is plugged into the plug-in cavity 8211 of the second connector 821, the first liquid outlet 8111 is in fluid communication with the connecting channel 8212, so that liquid can enter the containing cavity 511.

[0087] In some embodiments, please refer to Figure 6The bottom of the second joint 821 is further provided with an air hole 8213, which connects the bottom of the insertion cavity 8211 with the outside air. The air hole 8213 is used for allowing the outside air to enter the containing cavity 511 through the connection channel 8212, or for allowing the air in the containing cavity 511 to be discharged to the outside through the connection channel 8212.

[0088] In some embodiments, referring to Figure 10 The top plate 522 is provided with a plurality of through holes 5221, which penetrate the top plate 522 along the thickness direction of the top plate 522, so as to fluidly connect the upper part and the lower part of the containing cavity 511. As an example, the connection channel 8212 is fluidly connected with the side wall of the powder bin cup 51 near the bottom, so as to allow the liquid to flow from the cavity bottom of the containing cavity 511 and brew the powder in the second direction Y.

[0089] In some embodiments, along the direction in which the opening of the containing cavity 511 is directed to the cavity bottom of the containing cavity 511, the hole diameter of the through hole 5221 gradually increases, and the cross section of the through hole 5221 is substantially conical or trumpet-shaped. By arranging the conical or trumpet-shaped through hole 5221 on the top plate 522, on one hand, it can avoid the hole diameter of the through hole 5221 being too large to cause the powder to directly fall to the cavity bottom and affect the brewing, and on the other hand, it can increase the pressure during the process in which the liquid flows from the cavity bottom in the second direction Y, thereby improving the brewing effect. For example, the powder can better maintain the taste of the beverage when it is brewed under hot water with high temperature and high pressure.

[0090] Referring to Figure 12 and Figure 12 When the powder bin assembly 50 is located at the second position, the powder bin assembly 50 is docked with the brewing assembly 20, the first joint 811 is inserted into the insertion cavity 8211 of the second joint 821 (as shown in ​ ), and under the sealing action of the second sealing member 812 and the third sealing member 813, the connection channel 8212 connects the first liquid outlet 8111 with the containing cavity 511. The outside hot water flows from the first liquid outlet 8111 of the first joint 811 to the connection channel 8212, and then enters the containing cavity 511 through the connection channel 8212. Under the adsorption action of the brewing assembly 20, the hot water extracts and brews the powder in the second direction Y. The brewed liquid is guided to the outside through the brewing joint 21.

[0091] The working process of the second liquid path component 82 for discharging air is as follows: during the movement of the powder bin assembly 50 from the middle position to the second position, when the powder bin assembly 50 just abuts against the brewing assembly 20, the accommodation cavity 511 of the powder bin assembly 50 is only in communication with the outside air through the connecting channel 8212 under the action of the fourth sealing element 23, while the first liquid path component 81 and the second liquid path component 82 are in a separated state, and as the powder bin assembly 50 continues to move upward, the gas in the accommodation cavity 511 is discharged to the outside through the connecting channel 8212, the plug-in cavity 8211 and the air hole 8213; as the powder bin assembly 50 continues to move upward, the first liquid path component 81 starts to abut against the second liquid path component 82, at this time, the first joint 811 and the second sealing element 812 seal the top of the plug-in cavity 8211 of the second joint 821, so that the gas in the accommodation cavity 511 is discharged downward to the outside through the air hole 8213 through the connecting channel 8212, until the powder bin assembly 50 moves to the second position, the first joint 811 and the second joint 821 are plugged in place, the second sealing element 812 seals the plug-in cavity 8211, and the third sealing element 813 seals the air hole 8213.

[0092] The working process of the second liquid path component 82 for discharging air is as follows: during the movement of the powder bin assembly 50 from the middle position to the second position, when the powder bin assembly 50 just abuts against the brewing assembly 20, the accommodation cavity 511 of the powder bin assembly 50 is only in communication with the outside air through the connecting channel 8212 under the action of the fourth sealing element 23, while the first liquid path component 81 and the second liquid path component 82 are in a separated state, and as the powder bin assembly 50 continues to move upward, the gas in the accommodation cavity 511 is discharged to the outside through the connecting channel 8212, the plug-in cavity 8211 and the air hole 8213; as the powder bin assembly 50 continues to move upward, the first liquid path component 81 starts to abut against the second liquid path component 82, at this time, the first joint 811 and the second sealing element 812 seal the top of the plug-in cavity 8211 of the second joint 821, so that the gas in the accommodation cavity 511 is discharged downward to the outside through the air hole 8213 through the connecting channel 8212, until the powder bin assembly 50 moves to the second position, the first joint 811 and the second joint 821 are plugged in place, the second sealing element 812 seals the plug-in cavity 8211, and the third sealing element 813 seals the air hole 8213.

[0093] In the present application, the liquid path assembly is provided as a first liquid path component 81 and a second liquid path component 82, and the first liquid path component 81 and the second liquid path component 82 are arranged at different positions, so that when hot water needs to be supplied to the powder bin assembly 50, that is, when the powder bin assembly 50 is in the second position and connected with the brewing assembly 20, the first liquid path component 81 and the second liquid path component 82 are in communication to achieve water supply; when hot water does not need to be supplied to the powder bin assembly 50, the first liquid path component 81 and the second liquid path component 82 are automatically separated due to the movement of the powder bin assembly 50, so that the inside of the powder bin assembly 50 can be directly communicated with the outside air, which can timely exhaust air when the powder bin assembly 50 is docked with the brewing assembly 20, avoid the gas in the accommodating cavity 511 of the powder bin assembly 50 being compressed into high-pressure gas, increase the difficulty of docking the powder bin assembly 50 with the brewing assembly 20, and can timely intake air when the powder bin assembly 50 is separated from the brewing assembly 20, avoid the negative pressure in the accommodating cavity 511 of the powder bin assembly 50, and increase the difficulty of separating the powder bin assembly 50 from the brewing assembly 20.

[0094] The extraction mechanism 1 in the present application includes a support 10, a brewing assembly 20, a power assembly 30, a powder bin assembly 50, a baffle assembly 40 and a scraper 60. The brewing assembly 20 is arranged on the support 10, and the brewing assembly 20 is located above the powder bin assembly 50. The power assembly 30 and the powder bin assembly 50 are arranged on the support 10, and the power assembly 30 is connected with the powder bin assembly 50, and the power assembly 30 drives the powder bin assembly 50 to move in an L-shaped trajectory relative to the support 10. When the powder bin assembly 50 needs to receive powder, the powder bin assembly 50 moves to a first position. At this time, the powder bin assembly 50 and the brewing assembly 20 are staggered in the vertical direction. After the powder bin assembly 50 completes the powder receiving, the powder bin assembly 50 is horizontally translated to be directly below the brewing assembly 20, and then vertically translated to a second position to be docked with the brewing assembly 20. At this time, the powder in the powder bin assembly 50 can be brewed. After the brewing is completed, the powder bin assembly 50 is vertically translated downward to be separated from the brewing assembly 20, and then the powder bin assembly 50 is horizontally translated to the first position, and the powder bin assembly 50 and the brewing assembly 20 are staggered in the vertical direction, so that the powder bin assembly 50 can be operated for the next time. The baffle assembly 40 is located below the powder bin assembly 50, and abuts against the powder bin assembly 50 during the vertical downward movement of the powder bin assembly 50 to push the powder cake (powder residue) in the powder bin assembly 50 out of the powder bin assembly 50. The scraper 60 is used to scrape away the powder cake pushed out of the powder bin assembly 50 when the powder bin assembly 50 is horizontally translated to the first position, so that the powder bin assembly 50 in the first position is in an empty state, so as not to occupy the powder bin assembly 50 and affect the next time of powder receiving of the powder bin assembly 50.

[0095] The setting that the powder bin assembly 50 is driven to make L-shaped movement by the power assembly 30 can make the bin opening of the powder bin assembly 50 keep positive upward, avoid the powder spilling out during the movement of the powder bin assembly 50, and through the setting of the baffle assembly 40, the powder cake can be cleaned during the movement of the powder bin assembly 50, which can effectively improve the cleaning efficiency.

[0096] The application also provides a full-automatic coffee machine embodiment, which comprises the above-mentioned extraction mechanism, and the structure and function of the extraction mechanism can be referred to the above-mentioned embodiments, which will not be described here.

[0097] The above-mentioned is only the embodiment of the application, and does not limit the patent scope of the application, and any equivalent structure or equivalent process transformation using the content of the application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the application.
