DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] like Figures 1 to 8 As shown, the first aspect of the technical solution of the present invention is applied, the extraction structure includes a support frame 10, an extraction component 20 and a drive component 30, the extraction component 20 has an extraction part 21 for extracting powder, the extraction component 20 has a sliding part 22, and a first slide groove 11 is provided on the support frame 10, the sliding part 22 extends into the first slide groove 11 and is slidably provided along the extension direction of the first slide groove 11; the drive component 30 is driven and connected to the extraction component 20, so that under the driving action of the drive component 30, the sliding part 22 slides along the first slide groove 11, so that the extraction component 20 moves along the extension direction of the first slide groove 11, so that the extraction part 21 extracts the powder.

[0034] By applying the technical solution of this embodiment, the extraction component 20 is driven by the driving component 30 so that the sliding part 22 on the extraction component 20 slides along the extension direction of the first slide groove 11 on the support frame 10, so that the extraction part 21 on the extraction component 20 performs an extraction operation on the powder to be extracted; wherein, the driving component 30 is movably connected to the extraction component 20 so that the extraction component 20 performs reciprocating motion along the extension direction of the first slide groove 11 to extract the powder to be extracted, thereby avoiding the use of a purely mechanical complex structure, and the overall structure is large, inconvenient to install, and high cost. The driving component 30 of the technical solution of the present invention is movably arranged, which simplifies the overall structure and has a low cost, thereby solving the problem of the relatively complex extraction structure of the coffee machine in the prior art.

[0035] Furthermore, the drive assembly 30 includes a drive component 31 and a transmission component 32; the transmission component 32 is rotatably arranged, and the drive component 31 is drivingly connected to the transmission component 32 to drive the transmission component 32 to rotate. The transmission component 32 is slidably connected to the extraction assembly 20, so that when the drive component 31 drives the transmission component 32 to rotate, the transmission component 32 drives the extraction assembly 20 to move along the extension direction of the first chute 11. In the above arrangement, one end of the transmission component 32 is connected to the drive component 31, and the other end of the transmission component 32 is connected to the extraction component 50. Because the transmission component 32 is slidably connected to the extraction component 50, the rotation of the transmission component 32 causes one end of the transmission component 32 to slide relative to the extraction component 50, and the extraction assembly 20 slides along the extension direction of the first chute 11 via the sliding portion 22 to move toward the powder to be extracted and extract it.

[0036] like Figure 2 and Figure 4 As shown, the driving component 31 includes a driving motor 310 and a driven component 311. The driven component 311 is rotatably mounted on the support frame 10. The output shaft of the driving motor 310 is drivingly connected to the driven component 311. The driven component 311 has a first rotating shaft 3110, and the transmission component 32 has a second rotating shaft 320. The support frame 10 is provided with a rotating hole 12, through which the first rotating shaft 3110 passes and is connected to the second rotating shaft 320. The driving motor 310 drives the driven component 311 to rotate, thereby driving the transmission component 32 to rotate, thereby moving the extraction assembly 20. In this arrangement, the driving motor 310 drives the driven component 311 to rotate, thereby driving the transmission component 32 to rotate. Consequently, one end of the transmission component 32 slides relative to the extraction assembly 20, causing the extraction assembly 20 to move along the extension direction of the first chute 11 to extract the powder to be extracted.

[0037] In this embodiment, the driven component 311 is a gear. A rack is provided on the outer circumference of the output shaft of the driving motor 310 and meshes with the gear, so that the driven component 311 is driven to rotate by the driving motor 310 .

[0038] Specifically, the support frame 10 is provided with two first limit switches 13, which are spaced apart. At least a portion of the driven component 311 is located between the two first limit switches 13, so that the two first limit switches 13 limit the movement range of the driven component 311 and the sliding range of the sliding portion 22 of the extraction assembly 20 within the first chute 11. With this arrangement, at least a portion of the driven component 311 rotatably contacts the two first limit switches 13, respectively, to limit the position of the driven component 311. Simultaneously, when the drive motor 310 drives the driven component 311 to rotate from at least a portion of the driven component 311 contacting and abutting one of the two first limit switches 13 to at least a portion of the driven component 311 contacting and abutting the other of the two first limit switches 13, the sliding portion 22 of the extraction assembly 20 slides from one end of the first chute 11 to the other end, thereby limiting the movement range of the driven component 311 and the sliding range of the sliding portion 22.

[0039] like Figure 2 As shown, a second slide groove 51 is provided on the extraction component 20, and a slider 52 is provided on the transmission component 32. The slider 52 is arranged in the second slide groove 51 and is slidably arranged along the extension direction of the second slide groove 51, so that the transmission component 32 and the extraction component 20 are slidably connected; wherein, the extension direction of the second slide groove 51 is set at an angle to the extension direction of the first slide groove 11. The above-mentioned arrangement is that the slider 52 on the transmission component 32 is set in the second slide groove 51 and is slidably set along the extension direction of the second slide groove 51, so that the transmission component 32 is slidably set relative to the extraction component 20, and then the driving component 31 drives the transmission component 32 to rotate to drive the slider 52 to slide in the second slide groove 51, and utilizes the crank slider 52 mechanism principle to make the extraction component 20 move along the extension direction of the first slide groove 11, and the extension direction of the first slide groove 11 and the extension direction of the second slide groove 51 must be set at an angle, so that when the slider 52 on the transmission component 32 slides along the extension direction of the second slide groove 51, the extraction component 20 can move along the extension direction of the first slide groove 11.

[0040] Specifically, the transmission component 32 has a snap-fit ​​portion 321, and the slider 52 is provided with a fixing hole 520. The snap-fit ​​portion 321 is rotatably inserted into the fixing hole 520, thereby rotatably connecting the snap-fit ​​portion 321 to the slider 52. With the snap-fit ​​portion 321 inserted into the fixing hole 520 of the slider 52 and rotatably arranged relative to the slider 52, the driving component 31 drives the transmission component 32 to rotate, thereby causing the slider 52 to slide along the extension direction of the second chute 51 through the rotation of the transmission component 32. The rotation of the transmission component 32 also imparts a force to the extraction assembly 20 in the direction of rotation of the transmission component 32, thereby causing the extraction assembly 20 to move along the extension direction of the first chute 11.

[0041] like Figures 5 to 8 As shown, the extraction component 20 includes a pressing component 40 and an extraction component 50; wherein, the pressing component 40 is used to compress the powder, and a through hole 41 is provided in the pressing component 40; the extraction component 50 is movably arranged relative to the pressing component 40, the driving component 30 is drivingly connected to the extraction component 50, and the extraction part 21 is arranged on the extraction component 50. The extraction part 21 is movably arranged in the through hole 41 under the drive of the extraction component 50 to extract the powder. In the above arrangement, the through hole 41 is provided through the pressing component 40, and the extraction part 21 on the extraction component 50 is movably provided in the through hole 41, so that the extraction component 20 moves along the extension direction of the first slide groove 11 under the drive of the driving component 30, and then the pressing component 40 contacts the powder to be extracted and compresses the powder during the contact process to play the role of compacting the powder. At the same time, when the pressing component 40 compresses the powder, the extraction part 21 on the extraction component 50 moves along the extension direction of the through hole 41 to the extraction hole 212 of the extraction part 21 and communicates with the through hole 41, and then after the pressing component 40 completes the compacting operation of the powder, liquid is provided to the extraction part 21 through the liquid inlet part 55, and the liquid flows through the extraction channel 211 and the extraction hole 212 into the through hole 41, and then the liquid flows out of the through hole 41 and contacts the powder to realize the extraction action of the powder.

[0042] Furthermore, a connecting groove 42 is provided in the pressing component 40. A positioning post 420 and an elastic member 421 are provided in the connecting groove 42. The positioning post 420 is connected to one end of the elastic member 421, and the other end of the elastic member 421 is connected to the extraction component 50. In this arrangement, one end of the elastic member 421 is fixedly connected to the positioning post 420, and the other end of the elastic member 421 extends through the connecting groove 42 and is fixedly connected to the extraction component 50. The pressing component 40 and the extraction component 50 are arranged to be relatively movable via the elastic member 421. When the driving assembly 30 drives the extraction assembly 20 to move along the extension direction of the first chute 11, the extraction component 50 is moved closer to the pressing component 40 by compressing the elastic member 421. When the extraction assembly 20 completes the extraction of the powder, the elastic member 421 rebounds and causes the extraction component 50 to move relatively away from the pressing component 40.

[0043] In this embodiment, the elastic member 421 is a spring.

[0044] like Figures 6 to 8As shown, the extraction assembly 20 further includes a fixing member 60, one end of which is connected to the pressing member 40, and the other end of the fixing member 60 has a limiting portion 61. The extraction member 50 is movably mounted on the fixing member 60. A limiting groove 53 is provided in the extraction member 50, and the limiting portion 61 extends into the limiting groove 53 and is slidably arranged along the extension direction of the limiting groove 53 to enable the extraction member 50 to move relative to the pressing member 40 along the extension direction of the limiting groove 53. In the above arrangement, one end of the fixing member 60 is fixedly connected to the pressing member 40 by a screw, and the limiting portion 61 at the other end of the fixing member 60 is inserted into the limiting groove 53 of the extraction member 50. When the extraction member 50 and the pressing member 40 move relative to each other, the limiting portion 61 on the fixing member 60 moves along the extension direction of the limiting groove 53 to enable the extraction member 50 to move relative to the pressing member 40 along the extension direction of the limiting portion 61.

[0045] Furthermore, the extraction component 50 is provided with a second limit switch 54, which is arranged corresponding to the fixing component 60. The second limit switch 54 limits the movement stroke of the fixing component 60, thereby limiting the sliding stroke of the limiting portion 61 of the fixing component 60 within the limiting groove 53. This arrangement is configured to limit the limiting portion 61 when the limiting portion 61 of the fixing component 60 moves along the extension direction of the limiting groove 53 on the extraction component 50 and contacts the second limit switch 54. At this time, the extraction component 50 and the pressing component 40 are tightly fitted together, thereby achieving the second limit switch 54 to limit the movement stroke of the limiting portion 61 of the fixing component 60.

[0046] Specifically, the extraction component 50 is provided with a liquid inlet portion 55, the extraction portion 21 has an extraction channel 211 and an extraction hole 212, the liquid inlet portion 55 is inserted in the extraction channel 211 and communicates with the extraction channel 211, the extraction channel 211 is communicated with the through hole 41 through the extraction hole 212, and the extraction component 50 includes a first sealing ring 550, at least part of which is clamped between the liquid inlet portion 55 and the hole wall of the extraction hole 212. In the above arrangement, the liquid inlet portion 55 is inserted into the extraction channel 211 of the extraction portion 21 and communicates with the extraction channel 211. An extraction hole 212 is opened on the outer wall of the extraction portion 21, so that when the extraction portion 21 is inserted into the through hole 41 and moves to a certain position, the extraction hole 212 is communicated with the through hole; the other end of the liquid inlet portion 55 is used to be connected to the water supply component to provide the extraction portion 21 with high-temperature liquid for extracting the powder to be extracted, and then when the extraction component 50 moves relative to the pressing component 40 until the extraction hole 212 of the extraction portion 21 is communicated with the through hole 41, the powder is extracted, and the gap between the liquid inlet portion 55 and the extraction portion 21 is sealed by the first sealing ring 550 to prevent water leakage when supplying water to the extraction portion 21.

[0047] It should be noted that the number of the first sealing rings 550 is not limited thereto and can be selected according to the operating conditions and actual needs. Optionally, the number of the first sealing rings 550 is one, two, three, four, five, or more.

[0048] Optionally, the extraction structure further includes a filter element 43, which is arranged at one end of the through hole 41 of the pressing component 40; in this way, when the press component moves to contact the powder and presses it, and the extraction hole 212 of the extraction part 21 of the extraction component 50 is connected to the through hole 41 of the pressing component 40, high-temperature water is provided to the extraction part 21 through the liquid inlet part 55 to flow through the extraction channel 211, the extraction hole 212 and the through hole 41, and is discharged from the through hole 41, and then passes through the filter element 43 to contact the powder to be extracted, so as to realize the extraction operation of the powder.

[0049] Optionally, the extraction structure further includes a second sealing ring 44, which is arranged on the outer peripheral wall of the pressing component 40; in this way, when the pressing component 40 moves toward the accommodating component for accommodating the powder to be extracted and contacts and presses the powder, the gap between the accommodating component and the pressing component 40 is sealed by the second sealing ring 44.

[0050] It should be noted that the number of the second sealing rings 44 is not limited thereto and can be selected according to the operating conditions and actual needs. Optionally, the number of the second sealing rings 44 is one, two, three, four, five, or more.

[0051] Optionally, the extraction structure further includes a third sealing ring 210, which is arranged on the outer peripheral wall of the extraction portion 21 to seal the gap between the extraction portion 21 and at least a portion of the through hole 41; in this way, when the extraction portion 21 is movably arranged in the through hole 41, the gap between the outer wall of the extraction portion 21 and at least a portion of the through hole 41 is sealed by the third sealing ring 210 to prevent water leakage when the extraction portion 21 passes water into the through hole 41 through the extraction hole 212.

[0052] It should be noted that the number of the third sealing rings 210 is not limited thereto and can be selected according to the operating conditions and actual needs. Optionally, the number of the third sealing rings 210 is one, two, three, four, five, or more.

[0053] Optionally, a groove 45 is provided on the pressing component 40, and the sliding portion 22 extends into the groove 45 and is slidably provided along the extension direction of the groove 45; in this way, after the driving component 30 drives the extraction component 20 to move along the extension direction of the first slide groove 11, the pressing component 40 contacts and presses the powder to be extracted, and at the same time, the extraction component 50 approaches the pressing component 40, and then the sliding portion 22 on the extraction component 50 slides along the extension direction of the groove 45 on the pressing component 40.

[0054] like Figures 2 to 4 As shown, the support frame 10 includes a support plate 14 and a support cover 15 connected to each other. The support plate 14 and the support cover 15 are arranged opposite each other. The support plate 14 is provided with a plurality of connecting posts 141, which are spaced apart to enclose a limiting region 16. The support cover 15 is provided with a plurality of connecting holes 151, which are connected to the connecting posts 141 in a one-to-one correspondence. The extraction assembly 20 is movably disposed within the limiting region 16. The above arrangement, through the limiting region 16, limits the extraction assembly 20, so that when the extraction assembly 20 moves, at least a portion of the extraction assembly 20 is prevented from crossing the limited region, thereby performing the extraction operation on the powder to be extracted.

[0055] like Figure 1 As shown, according to the second aspect of the technical solution of the present invention, the coffee machine includes an extraction structure and a material receiving structure 70. The extraction structure is used to extract the powder located in the material receiving structure 70. The material receiving structure 70 is provided with a material receiving trough for accommodating the powder, so that the pressing component 40 of the extraction structure can extend into the material receiving trough and compact the powder located in the material receiving trough, and then the extraction component 50 of the extraction structure can extract the compacted powder. The extraction structure is the extraction structure mentioned above.

[0056] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0057] The extraction structure includes a support frame, an extraction component and a drive component. The extraction component has an extraction part for extracting powder. The extraction component has a sliding part. A first slide groove is provided on the support frame. The sliding part extends into the first slide groove and is slidably arranged along the extension direction of the first slide groove. The drive component is connected to the extraction component so that under the driving action of the drive component, the sliding part slides along the first slide groove, so that the extraction component moves along the extension direction of the first slide groove, so that the extraction part extracts the powder. The above arrangement drives the extraction component through the driving component so that the sliding part on the extraction component slides along the extension direction of the first slide groove on the support frame, so that the extraction part on the extraction component performs an extraction operation on the powder to be extracted; wherein, the driving component is movably connected to the extraction component so that the extraction component makes a reciprocating motion along the extension direction of the first slide groove to extract the powder to be extracted, thereby avoiding the use of a purely mechanical complex structure, and the overall structure is large, inconvenient to install, and high cost. The driving component of the technical solution of the present invention is movably arranged, which simplifies the overall structure and has a low cost, thereby solving the problem of the relatively complex extraction structure of the coffee machine in the prior art.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments can have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0060] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0061] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.
