Referring to fig. 1 and 2, extraction mechanism 1 includes a support 10, a brewing assembly 20, a power assembly 30, a baffle assembly 40, a powder bin assembly 50, and a scraper 60. A brewing assembly 20 is provided in the holder 10, the brewing assembly 20 being 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 positioned below the brewing assembly 20,

the power assembly 30 is connected with the powder bin assembly 50, and the power assembly 30 is used for driving the powder bin assembly 50 to do L-shaped track reciprocating motion relative to the bracket 10, so that the powder bin assembly 50 achieves horizontal translational motion and vertical translational motion.

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, so that the powder bin assembly 50 is convenient for receiving powder, after the powder bin assembly 50 receives powder, the powder bin assembly 50 horizontally translates to the position right below the brewing assembly 20, namely to the middle position, and then vertically upwards translates to a second position, the powder bin assembly 50 is in butt joint with the brewing assembly 20, and at this time, powder in the powder bin assembly 50 can be brewed. After brewing, the powder bin assembly 50 is firstly vertically and downwards translated to a middle position, the powder bin assembly 50 is separated from the brewing assembly 20, then the powder bin assembly 50 is horizontally translated to a 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 carry out the next powder receiving operation.

The baffle assembly 40 is arranged on the bracket 10, and the baffle assembly 40 is positioned below the powder bin assembly 50 and is abutted with the powder bin assembly 50 in the process of vertically downwards moving the powder bin assembly 50 after the powder is brewed, so that the powder cake (powder slag) in the powder bin assembly 50 after the powder is brewed is pushed out of the powder bin assembly 50. The scraper 60 is disposed on the support 10, and the scraper 60 is configured to scrape the cake pushed out of the powder bin assembly 50 during the process of horizontally translating the powder bin assembly 50 from the middle position to the first position, so that the powder bin assembly 50 restored to the first position is in an empty bin state, so as to prevent the previous cake from occupying the powder bin assembly 50 and affecting the next powder receiving of the powder bin assembly 50.

For the convenience of the reader in understanding the inventive concepts of the present application, the following description is made throughout the brewing process:

the first position (shown in fig. 9) is where the powder bin assembly 50 receives powder, and when the powder bin assembly 50 is in the first position, the powder bin assembly 50 is vertically offset from the brewing assembly 20, so that the powder bin assembly 50 can perform a powder receiving operation.

The second position (as shown in fig. 7 or 10) is where the cartridge assembly 50 is docked with the brewing assembly 20 and the cartridge assembly 50 is brewing.

The intermediate position refers to a position in which 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. 8 or 11), wherein the intermediate position is also a position in which the direction of movement of the powder bin assembly 50 changes when the powder bin assembly 50 moves between the first position and the second position.

Wherein, the brewing process of the beverage comprises the following steps: referring to fig. 9, the powder bin assembly 50 is initially located at a first position, after powder for brewing beverage, such as coffee powder, is placed in the accommodating cavity 511 of the powder bin assembly 50, the power assembly 30 is started, the powder bin assembly 50 is horizontally moved from the first position to an intermediate position along a first direction X under the driving action of the power assembly 30, referring to fig. 10, and then the powder bin assembly 50 is driven to move to a second position along a second direction Y, at this time, the powder bin assembly 50 is in butt joint with the brewing assembly 20, and the baffle assembly 40 is abutted against the end of the push rod 52 in the powder bin assembly 50 far away from the brewing assembly 20, at this time, the beverage can be formed for brewing the powder in the powder bin assembly 50. After the brewing process is completed, the power assembly 30 is driven in a reverse direction, see fig. 11, so that the powder bin assembly 50 moves in the opposite direction of the second direction Y until the powder bin assembly 50 moves to the middle position, and the powder bin assembly 50 is separated from the brewing assembly 20, at this time, since the baffle assembly 40 abuts against the end of the powder bin assembly 50, which is far away from the brewing assembly 20, of the push rod 52, 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 in the opposite direction of the second direction Y, the powder bin assembly 50 moves in the opposite direction of the first direction X under the continued driving of the power assembly 30, and when the powder bin assembly 50 moves in 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 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 separated from abutting, the push rod 52 is reset, the push rod 52 does not occupy the accommodating cavity 511 any more, the accommodating cavity 511 is in an empty bin state, and the accommodating cavity 511 is used for the next powder receiving operation.

It should be noted that: the first direction X and the second direction Y are substantially perpendicular. The horizontal translation refers to a direction in which the motion direction is parallel to the carrying surface of the object when the extraction mechanism 1 is placed on the carrying surface of the object, and the vertical translation refers to a direction in which the motion direction is perpendicular to the carrying surface of the object when the extraction mechanism 1 is placed on the carrying surface of the object, for example: 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.

It will be appreciated that: in some embodiments, the movement of the cartridge assembly 50 from the first position to the intermediate position may be a horizontal translation in the first direction X or an upward tilting movement. Of course, the powder hopper assembly 50 may be horizontally translated in the first direction X or may be moved obliquely downward when returning from the neutral position to the first position.

For the above-mentioned bracket 10, referring to fig. 2 and 3, the bracket 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 in a substantially parallel manner, the first side plate 11 and the second side plate 12 are fixedly connected, and 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 disposed outside the first side plate 11 or the second side plate 12, so as to avoid the power assembly 30 occupying the space between the first side plate 11 and the second side plate 12.

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 which are connected, wherein the first section 1111 extends along the first direction X, the second section 1112 extends along the second direction Y, and an inflection point is formed at the junction of the first section 1111 and the second section 1112, so that the first track groove 111 is substantially L-shaped. Referring to fig. 1, the powder bin assembly 50 is provided with a protruding first supporting point 561, the first supporting point 561 is inserted into the first track groove 111, and the powder bin assembly 50 moves along the first track groove 111 under the driving action of the power assembly 30.

In order to make the left and right sides of the powder bin assembly 50 move more smoothly, the second side plate 12 is provided with a second track groove 121, and the second track groove 121 includes a third segment 1211 and a fourth segment 1212 which are communicated, wherein the third segment 1211 extends along the first direction X, the fourth segment 1212 extends along the second direction Y, and an inflection point is formed at the junction of the third segment 1211 and the fourth segment 1212, so that the second track groove 121 is substantially L-shaped. Referring to fig. 2, the powder bin assembly 50 is provided with a second supporting point 562, wherein the first supporting point 561 and the second supporting point 562 are respectively located at two opposite sides of the powder bin assembly 50, the second supporting point 562 is inserted into the second track groove 121, and the powder bin assembly 50 moves along the second track groove 121 under the driving action of the power assembly 30.

In order to prevent the powder bin assembly 50 from rotating during the movement process, at least two fulcrums are arranged on the same side of the powder bin assembly 50, so that the stability of the powder bin assembly 50 can be effectively improved. Referring to fig. 1, the powder bin assembly 50 is further provided with a third supporting point 563, and the first supporting point 561 and the third supporting point 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 track groove 112, and the third track groove 112 comprises a fifth segment 1121 and a sixth segment 1122 which are communicated, 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 junction of the fifth and sixth sections 1121, 1122 such that the third track groove 112 is also generally L-shaped, with the third fulcrum 563 inserted into the third track groove 112.

In some embodiments, referring also to FIG. 2, the cartridge assembly 50 is further provided with a fourth fulcrum 564, the second fulcrum 562 and the fourth fulcrum 564 being on the same side of the cartridge assembly 50. Correspondingly, the second side plate 12 is further provided with a fourth track groove 122, the fourth track groove 122 comprising 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 junction of the seventh and eighth sections 1221 and 1222 such that the fourth track groove 122 is also generally L-shaped, with the fourth fulcrum 564 being inserted into the third track groove 112.

In some embodiments, the two L-shaped track grooves on the first side plate 11 and the second side plate 12 are arranged at the places where the two L-shaped track grooves are overlapped in a crossing way, so that the volumes of the first side plate 11 and the second side plate 12 can be effectively reduced, the whole volume of the extraction mechanism 1 is reduced, and the design requirement of equipment miniaturization is met.

As an example, referring to fig. 3, first section 1111 intersects and communicates with sixth section 1122 such that third fulcrum 563 may span first section 1111. During movement of the powder bin assembly 50, when the first fulcrum 561 moves to the connection between the first section 1111 and the sixth section 1122, the third fulcrum 563 is still in the fifth section 1121, i.e. the powder bin assembly 50 can only continue to move in the first direction X and cannot move in the second direction Y, and only when the first fulcrum 561 moves to the connection between the first section 1111 and the second section 1112, the third fulcrum 563 moves to the connection between the fifth section 1121 and the sixth section 1122, the powder bin assembly 50 can move in the second direction Y. The arrangement of the first track groove 111 and the third track groove 112 in a local cross overlapping manner can effectively reduce the volume of the first side plate 11, and does not influence the movement of the powder bin assembly 50.

In other embodiments, the depth of the first trajectory groove 111 is different from the depth of the third trajectory groove 112 in the thickness direction of the first side plate 11, and the problem that the movement of the first fulcrum 561 and the third fulcrum 563 is affected can be solved.

Similarly, referring to FIG. 3, third segment 1211 intersects and communicates with eighth segment 1222 such that fourth fulcrum 564 may span third segment 1211. The movement of the second fulcrum 562 and the fourth fulcrum 564 of the cartridge assembly 50 may be analyzed with respect to the first fulcrum 561 and the third fulcrum 563 described above, and will not be described again.

In some embodiments, to increase the smoothness of the first, second, third and fourth fulcra 561, 562, 563, 564 as they move in the corresponding track grooves, pulleys or bearings may be mounted at the four fulcra such that the movement between the four fulcra and the first and second side plates 11, 12 is changed from relative sliding to relative rolling, thereby reducing the friction as the powder bin assembly 50 moves on the first and second side plates 11, 12.

In some embodiments, referring to fig. 3, the bracket 10 further includes a bottom plate 13, the bottom plate 13 is disposed at the bottoms of the first side plate 11 and the second side plate 12, and one end of the bottom plate 13 is connected to the first side plate 11, and the other end of the bottom plate 13 is connected to the second side plate 12, so that the strength and rigidity of the bracket 10 can be enhanced and the stability of the bracket 10 can be improved through the first side plate 11 and the second side plate 12 connected to the bottom plate 13.

For the above brewing assembly 20, referring to fig. 4 and 8, the brewing assembly 20 is located above the powder bin assembly 50, the brewing assembly 20 includes a brewing connector 21 and a filter 22, the brewing connector 21 is disposed between the first side plate 11 and the second side plate 12, the brewing connector 21 is in communication with an external pipeline, and the brewing connector 21 is used for conveying 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, which is close to the bottom plate 13, when the brewing assembly 20 is in butt joint with the powder bin assembly 50 and is brewed, the filter 22 is used for blocking powder which is still solid in the powder bin assembly 50, so that the solid powder in the brewing process is prevented from entering the brewing connector 21, the brewing connector 21 is blocked, and meanwhile, the influence of a large amount of solid powder in the beverage on the taste is avoided.

the push rod 52 pushes out the cake of powder located in the powder bin cup 51.

As an example, the powder bin cup 51 is provided with a receiving cavity 511, and the top of the powder bin cup 51 is provided with a bin opening communicating with the receiving cavity 511, the receiving cavity 511 being for storing powder to be brewed. The push rod 52 includes a rod 521 and a top plate 522, the top plate 522 is disposed in the accommodating chamber 511, a first end of the rod 521 is connected to the top plate 522, and a second end of the rod 521 protrudes from the bottom of the powder bin cup 51. Rod 521 is movable relative to powder cup 51 to urge top plate 522 to move within containment chamber 511.

When the power assembly 30 drives the powder bin cup 51 to move from the first position to the second position, the rod 521 in the push rod 52 is firstly abutted against the transition part 412 of the sliding plate 41, and as the powder bin cup 51 continues to move, the rod 521 pushes the sliding plate 41 in the baffle assembly 40 to move towards the avoiding position, when the powder bin assembly 50 moves to the second position, the second end of the rod 521 and the sliding plate 41 do not have an abutting relationship in the first direction X or the third direction Z, but the second end of the rod 521 and the sliding plate 41 do not abut or just abut against each other in the second direction Y, and as shown in fig. 7, the sliding plate 41 moves from the avoiding position to the blocking position under the action of the first elastic piece 42; when the powder bin 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, and as the powder bin cup 51 continues to move downwards, the rod 521 drives the top plate 522 to move in the accommodating cavity 511, so that the powder cake is ejected out of the accommodating cavity 511, as shown in fig. 8.

In some embodiments, referring to fig. 6, the top plate 522 has a diameter equal to the inner diameter of the receiving cavity 511 of the powder cup 51, i.e., the push rod 52 and the powder cup 51 form a piston structure.

In some embodiments, referring to fig. 5 and 6, the powder bin assembly 50 further includes a second elastic member 53, the second elastic member 53 is located outside the powder bin cup 51, the second elastic member 53 is sleeved on the rod 521, and two ends of the second elastic member 53 respectively abut against the second end of the rod 521 and the bottom of the powder bin cup 51. The second elastic member 53 is used for providing elastic force so that the rod 521 drives the top plate 522 to move toward the bottom of the accommodating chamber 511. As an example, the second elastic member 53 is a spring.

In some embodiments, referring to fig. 5 and 6, the powder bin assembly 50 further includes a first sealing member 54, the first sealing member 54 is disposed at the bottom of the powder bin cup 51, and the first sealing member 54 abuts against the rod 521, so as to seal the gap between the rod 521 and the powder bin cup 51, and prevent the liquid in the accommodating cavity 511 from flowing out from the gap between the powder bin cup 51 and the rod 521 during the brewing process.

As an example, when 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 positions of the brewing connector 21 and the powder bin cup 51 are fixed, the third elastic member 55 is used for adjusting the distance between the top plate 522 and the filter 22, so that the space between the top plate 522 and the filter 22 is changed, in particular, when more powder is present, the distance between the top plate 522 and the filter 22 is larger, and when less powder is present, the distance between the top plate 522 and the filter 22 is smaller, but no matter what amount of powder is, the top plate 522 can always compress the powder between the filters 22 under the action of the third elastic member 55, that is, the top plate 522 provides pressure to the powder to compress the powder, so that extraction is achieved. As an example, the containment chamber 511 may contain 5-20 grams of coffee grounds.

It will be appreciated that the powder, such as coffee powder, may need to be compacted during the brewing process to achieve extraction, and that the distance between the top plate 522 and the filter 22 is constant after the cartridge assembly 50 is docked with the brewing assembly 20 without the provision of the third resilient member 55. When a smaller amount of powder is positioned between the top plate 522 and the filter element 22, the top plate 522 cannot compact the powder, the powder is in a loose state, and hot water is introduced at the moment, so that the powder is only washed once, and not extracted, and the taste of the beverage is greatly reduced. Through setting up third elastic component 55, can adjust the distance between roof 522 and the filter media 22 to when making to add the powder of different components, roof 522 can compress tightly the powder all the time, thereby the hot water of the high temperature high pressure of being convenient for let in extracts the powder that compresses tightly.
