The extraction mechanism is located below the capsule chute, and the switch structure is located between the capsule chute and the extraction mechanism. The switch structure can block or give way to the lower end of the capsule chute, thereby allowing or stopping the capsule cup in the capsule chute from falling to the extraction mechanism. When the user needs a drink, the switch structure can be controlled to give way to the lower end of the capsule chute, so that the capsule cup falls into the extraction mechanism, and then the drink is extracted and provided to the user. However, due to humid weather or long-term storage, there may be adhesion or jamming between the capsule cup and the capsule chute. After the switch structure gives way to the lower end of the capsule chute, the capsule cup is still stuck at the lower end of the capsule chute and cannot fall to the extraction mechanism, so that the capsule extractor cannot work normally.

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Reference Figures 1 to 4 , which is a capsule extraction machine of an embodiment of the utility model, comprises a machine base 100, a material storage rack 200 and a material shifting mechanism 300. The material storage rack 200 is arranged on the machine base 100, and a capsule chute 210 is arranged vertically on the material storage rack 200; the material shifting mechanism 300 is arranged on the machine base 100, and the material shifting mechanism 300 comprises a material shifting driver and a material shifting part, and the material shifting driver is used to drive the material shifting part to approach or move away from the capsule cup at the lower end of the capsule chute 210.

[0035] When the user needs to extract a beverage, if the capsule cup at the lower end of the capsule chute 210 cannot fall, the material-digging driver of the material-digging mechanism 300 can drive the material-digging part to move toward the lower end of the capsule chute 210 first, and then reset. The material-digging part impacts and shakes the capsule cup to adjust the posture of the capsule cup so that the capsule cup can slide away from the lower end of the capsule chute 210 and fall, thereby reducing the risk of the capsule cup being stuck in the capsule chute 210, so that the capsule extraction machine can work normally.

[0036] Specifically, the material-dispensing driver can be an electric push rod, and the material-dispensing part is one end of the electric push rod, and the electric push rod can be linearly extended and retracted to impact and shake the capsule cup. It is understandable that the material-dispensing driver can also be a structure that outputs linear power, such as a cylinder, in which case the material-dispensing part can be a part of the cylinder rod, or a push piece installed on the material-dispensing driver. It is conceivable that the material-dispensing driver can also be a motor, and the material-dispensing part is a swing arm, and the motor drives the swing arm to reciprocate to impact and shake the capsule cup.

[0037] Specifically, the capsule cup is shaped like a sealed cup, and a flange is provided outwardly around the periphery of the capsule cup cover. The side wall of the capsule chute 210 is provided with a flange limiting groove, and the capsule cup cover is slidably provided in the capsule chute 210, and the flange of the cup cover is slidably limited in the flange limiting groove. It is conceivable that the capsule chute 210 can also be a through hole with a similar cross-sectional shape to the capsule cup, and can also play the same function. Those skilled in the art can make specific configurations according to actual needs.

[0038] Specifically, the material-digging mechanism 300 is located on one side of the material storage rack 200 in the horizontal direction, and the material-digging driver can drive the material-digging part to approach or move away from the lower end of the capsule chute 210, so as to hit and straighten the flange part of the capsule cup cover end to be parallel to the flange limiting groove, so that the capsule cup can slide smoothly along the capsule chute 210, and the capsule cup is kept in the capsule chute 210 and will not slip out of the capsule chute 210 in the horizontal direction. It is conceivable that in some embodiments, the material-digging mechanism 300 can also be located inside the material storage rack 200, in which case the material-digging part can be telescopically connected to the material storage rack 200 and can telescopically hit and shake the capsule cup in the capsule chute 210.

[0039] In the embodiment, the device further comprises a control module and a first capsule detector 400, the first capsule detector 400 is opposite to the lower end of the capsule chute 210, and the control module is electrically connected to the first capsule detector 400 and the material-dispensing driver. When the switch structure 600 gives way to the lower end of the capsule chute 210, the first capsule detector 400 detects whether the position of the capsule cup at the lower end of the capsule chute 210 changes. When it is detected that the capsule cup is stuck, the control module can start the material-dispensing driver, and the material-dispensing driver drives the material-dispensing part to impact and shake the capsule cup, so that the capsule cup adjusts its posture to get out of the stuck state and can smoothly fall to the extraction mechanism 500, thereby providing a physical basis for the automation of the device.

[0040] Specifically, the first capsule detector 400 may be a photoelectric sensor or a displacement sensor, for example, to detect the position of the capsule cup. The control module may be a circuit board or a single-chip microcomputer, for example.

[0041] In the embodiment, the extraction mechanism 500 and the switch structure 600 are also included. The base 100 is provided with a feeding hole 110. The storage rack 200 is arranged with ten capsule chutes 210. The storage rack 200 is movably provided on the base 100 and can move relative to the base 100 to a position where the lower end of one of the capsule chutes 210 is vertically opposite to the feeding hole 110. The extraction mechanism 500 is located below the feeding hole 110. The switch structure 600 is provided on the base 100 and can cover or open the feeding hole 110. The base 100 covers the lower ends of all capsule chutes 210 in the area outside the feeding hole 110. Ten capsule chutes 210 are provided, and the storage rack 200 can movably switch different capsule chutes 210 to align with the feeding hole 110. Different capsule chutes 210 can store capsules of different beverage types, which is convenient for users to choose different beverages and improves the richness of beverages. When the user selects a drink, the corresponding capsule chute 210 moves to the top of the drop hole 110, and then the switch structure 600 can open the drop hole 110, so that the capsule cup of the capsule chute 210 above the drop hole 110 falls to the extraction mechanism 500; during this period, the lower ends of the capsule chutes 210 in the area outside the drop hole 110 are blocked by the machine base 100 to prevent the capsule cups of other capsule chutes 210 from leaving the capsule chute 210.

[0042] It is understandable that the number of capsule chutes 210 provided in the storage rack 200 may also be other numbers, such as two, three, four or more numbers, and those skilled in the art may make specific configurations according to actual needs.

[0043] In the embodiment, a material changing driver is further included, the material storage rack 200 is rotatably disposed on the machine base 100 and the rotation axis is disposed vertically, all capsule chutes 210 are arranged around the rotation axis of the material storage rack 200, and the material changing driver is disposed on the machine base 100 and is used to drive the material storage rack 200 to rotate so as to switch different capsule chutes 210 to be opposite to the material drop hole 110. By driving the material storage rack 200 to switch different capsule chutes 210 to be opposite to the material drop hole 110 in a rotating manner, the volume of the material storage rack 200 can be reduced, thereby facilitating the miniaturization requirements of the capsule extraction machine.

[0044] Specifically, the material change driver is a motor, and a servo motor or other motor with relatively precise angle control can be used. The output shaft of the motor can be directly connected to the storage rack 200, or the storage rack 200 can be driven to rotate through a belt drive structure or a gear drive structure. It is understandable that in some embodiments, the material change driver can also be other structures that output rotational power, such as a rotary cylinder. It is conceivable that the storage rack 200 can also switch different capsule chutes 210 to align with the drop hole 110 through other movement methods. For example, the storage rack 200 is slidably connected to the base 100 through a slide rail slider structure. The material change driver can use an electric cylinder to drive the storage rack 200 to slide. At this time, a plurality of capsule chutes 210 can be arranged along the sliding direction to achieve switching and selecting different capsule cups.

[0045] In the embodiment, the base 100 is provided with a drop stopper 120, which is higher than the lower end of the capsule chute 210 and is located above the drop hole 110. The drop stopper 120 is provided, and after the switch structure 600 opens the drop hole 110, the drop stopper 120 can allow the capsule below it to pass through the drop hole 110 and enter the extraction mechanism 500, while stopping the capsule cup above it from falling, so that each time the switch structure 600 opens the drop hole 110, only one capsule cup can fall through the drop hole 110, thereby reducing the risk of multiple capsule cups accidentally entering the extraction mechanism 500 at one time and reducing the risk of abnormal operation of the extraction mechanism 500.

[0046] Specifically, the distance between the falling baffle 120 and the opening of the material drop hole 110 should be equal to or slightly larger than the size of a capsule cup, so as to allow the storage rack 200 to drive the capsule cups thereon to rotate and enter between the falling baffle 120 and the material drop hole 110. When the distance between the falling baffle 120 and the opening of the material drop hole 110 is slightly larger than the diameter of a capsule cup, in addition to preventing the capsule cups above from falling, each time the storage rack 200 rotates, the falling baffle 120 can push the capsule cups to rotate and move up and down to a certain extent when the capsule chute 210 passes through the falling baffle 120, thereby solving the problem that the capsule chute 210 is too long and there are too many capsule cups, causing the capsule cups to get stuck in the capsule chute 210.

[0047] In the embodiment, an extraction mechanism 500 is also included, which is arranged on the machine base 100 and located below the capsule chute 210; the extraction mechanism 500 includes a limiting seat 510, a material transfer seat 520, a capsule cover end clamping assembly 530 and a material transfer driver 540, the limiting seat 510 is provided with a capsule bottom end accommodating hole, the hole wall of the capsule bottom end accommodating hole is provided with a first liquid passing needle, the capsule cover end clamping assembly 530 is connected to the material transfer seat 520, the material transfer seat 520 is provided with a second liquid passing needle 521, the material transfer seat 520 is movably arranged on the machine base 100 and enables the capsule cover end clamping assembly 530 to move toward or away from the capsule bottom end accommodating hole and pass under the capsule chute 210, and the material transfer driver 540 is arranged on the machine base 100 and is used to drive the material transfer seat 520 to move. Before extraction, the capsule cover end clamping assembly 530 moves to the bottom of the capsule chute 210. After the capsule cup in the capsule chute 210 falls, the cover end of the capsule cup is clamped by the capsule cover end clamping assembly 530. Then, the material transfer driver 540 drives the material transfer seat 520 to move. The capsule cover end clamping assembly 530 drives the bottom end of the capsule cup to insert into the capsule bottom end receiving hole. During this period, the first liquid needle and the second liquid needle 521 are respectively inserted into the capsule cup. The second liquid needle 521 can inject hot water into the capsule cup, and the first liquid needle can receive the extracted liquid in the capsule cup and transport the liquid to a designated position to facilitate the preparation of a beverage. After extraction, the capsule cup is reset with the material transfer seat 520 and leaves the capsule bottom end receiving hole. The above structure can automatically complete the material receiving and extraction of the capsule cup. It has a simple structure and is conducive to the miniaturization trend of the capsule extraction machine.

[0048] It is understandable that in other embodiments, the first liquid-passing needle may be injected with hot water, and the second liquid-passing needle 521 may receive the extracted liquid. Those skilled in the art may make specific configurations according to actual needs.

[0049] In the embodiment, the limiting seat 510 and the material transfer seat 520 are arranged in the left-right direction, the material transfer seat 520 is slidably arranged on the machine base 100 in the left-right direction, the first liquid-passing needle is arranged at the bottom of the capsule bottom end receiving hole in the left-right direction, the hole axis of the capsule bottom end receiving hole is arranged in the left-right direction, the orifice of the capsule bottom end receiving hole is opposite to the second liquid-passing needle 521, the second liquid-passing needle 521 is arranged in the left-right direction, the capsule cover end clamping assembly 530 is located between the material transfer seat 520 and the limiting seat 510, and the second liquid-passing needle 521 and the capsule cover end clamping assembly 530 are arranged at intervals in the left-right direction. When the capsule cover end clamping assembly 530 clamps the cover end of the capsule cup, the second liquid-passing needle 521 is not inserted into the capsule cup. When the material moving driver 540 drives the material moving seat 520 to move toward the limiting seat 510, and the capsule cover end clamping assembly 530 inserts the capsule cup into the capsule bottom end receiving hole along the left and right directions, the capsule cover end clamping assembly 530 releases the cover end of the capsule cup. At this time, the material moving seat 520 moves toward the limiting seat 510 and pushes the top of the capsule cup into the capsule bottom end receiving hole until it is in place, and allows the first liquid passing needle and the second liquid passing needle 521 to be inserted into the capsule cup, so that the capsule cup limiting and extraction needle insertion processes can be completed at one time, shortening the preparation time, making the capsule extraction machine faster to use, and simplifying the structure of the capsule extraction machine.

[0050] Specifically, the material transfer seat 520 is connected to the machine base 100 in a sliding manner along the left and right direction through the guide column and guide sleeve structure, and the material transfer driver 540 is a linear driver, which can be a structure such as a cylinder, an electric cylinder or a motor with a lead screw and a lead screw nut, etc., to drive the material transfer seat 520 to move left and right, and those skilled in the art can make specific configurations according to actual needs. It is understandable that the material transfer seat 520 can also be connected to the machine base 100 in a sliding manner through a slide rail and slider structure.

[0051] It is conceivable that in other embodiments, the material transfer seat 520 can also be swingably connected to the base 100, so that the capsule cover end clamping assembly 530 moves under the capsule chute 210 and the capsule cup is placed in the capsule bottom receiving hole. In this case, the material transfer driver 540 is a rotation driver, such as a servo motor or a rotary cylinder, etc., which outputs a rotational power, and the material transfer seat 520 is swung relative to the base 100 by a rotational connection of a rotating shaft.

[0052] In an embodiment, the capsule cover end clamping assembly 530 includes an elastic member 531 and two clamping arms 532, the upper ends of the two clamping arms 532 are pivotally connected to the material transfer seat 520, the elastic member 531 is arranged between the two clamping arms 532 and can apply a force to close the two clamping arms 532, the lower ends of the two clamping arms 532 are arranged at intervals and form a cup body yield opening 533, a cover end limiting groove 550 is formed between the capsule cover end clamping assembly 530 and the material transfer seat 520, the groove of the cover end limiting groove 550 is arranged downward, and the machine base 100 is provided with a waste collection port, which is located below the extraction mechanism 500.

[0053] Before the capsule cup is inserted into the bottom receiving hole of the capsule, the elastic member 531 causes the two clamping arms 532 to close and clamp the cover end of the capsule cup. When the capsule cup enters the bottom receiving hole of the capsule, the capsule cover end clamping assembly 530 releases the cover end of the capsule cup and allows the cover end of the capsule cup to pass over the capsule cover end clamping assembly 530 and directly abut against the material transfer seat 520. At this time, the cover end of the capsule cup is located in the cover end limiting groove 550. When the material transfer seat 520 moves away from the limiting seat 510, that is, when the capsule cup leaves the bottom receiving hole of the capsule, the capsule cover end clamping assembly 530 closes again, and the cover end of the capsule cup is located in the cover end limiting groove 550. The capsule cover end clamping assembly 530 and the material transfer seat 520 limit the left and right positions of the cover end of the capsule cup, so that the capsule cup can be completely pulled out of the bottom receiving hole of the capsule. Since the lower ends of the two clamping arms 532 form a cup body clearance opening 533, and the notch of the cover end limiting groove 550 faces downward, after the capsule cup is separated from the limiting seat 510, it can be separated from the extraction mechanism 500 directly through the cup body clearance opening 533 and the notch of the cover end limiting groove 550 under the action of gravity, and fall into the waste recovery port below for easy recovery. The above-mentioned extraction mechanism 500 has a simple structure, a simple process and good reliability, and the process of discarding waste capsules is relatively simple. When the capsule cup is inserted into the capsule bottom end receiving hole, the two clamping arms 532 loosen the cover end of the capsule cup, so that the material transfer seat 520 can directly push the capsule cup into place, so that the second liquid needle 521 and the first liquid needle can be inserted into the capsule cup, simplifying the working process.

[0054] Specifically, the elastic member 531 is a spring, and the two ends of the spring are respectively connected to the two clamping arms 532. It is conceivable that the elastic member 531 can also be other structures, such as springs, etc., or two elastic members 531 can be provided, and the elastic member 531 is a torsion spring, which is connected between the clamping arm 532 and the material transfer seat 520 and applies elastic force to the clamping arm 532, so that the two clamping arms 532 are closed.

[0055] In the embodiment, the clamping arm 532 and the limiting seat 510 are provided with a guide surface 560, and the limiting seat 510 can push the two clamping arms 532 to open through the guide surface 560. The clamping arms 532 are pushed to open by the inclined surface, and the structure is simple and easy to implement. It is conceivable that the guide surface 560 can also be an arc-shaped surface; it can be provided with the guide surface 560 on either the clamping arm 532 or the limiting seat 510.

[0056] It is conceivable that the capsule cover end clamping assembly 530 may also be other structures, for example, including two clamping arms 532, a motor and a gear set. One end of the clamping arm 532 is pivotally connected to the material transfer base 520, and the motor drives the two clamping arms 532 to rotate in opposite directions through the gear set to achieve closing or opening, so as to clamp or release the capsule cup.

[0057] In an embodiment, a capsule ejection structure is provided on the bottom wall of the capsule bottom receiving hole. The capsule ejection structure is provided to facilitate the initial pushing of the capsule cup top out of the capsule bottom receiving hole by a certain distance when the material transfer seat 520 is away from the limiting seat 510 after the extraction is completed, so that when the capsule cover end clamping assembly 530 is closed again, the cover end of the capsule cup is kept in the cover end limiting groove 550, and the material transfer seat 520 cooperates with the capsule cover end clamping assembly 530 to pull the capsule cup out of the capsule bottom receiving hole.

[0058] Specifically, the capsule ejection structure can be a spring with an ejector pin. When the capsule cup enters the bottom accommodation hole of the capsule, the spring is compressed by the ejector pin. When the material transfer seat 520 is away from the limit seat 510, the spring is reset and the capsule cup is ejected a certain distance by the ejector pin. The structure is simple and the cost is low. It is conceivable that the capsule ejection structure can also adopt other structures that output linear power, such as electric push rods, and those skilled in the art can make specific configurations according to actual needs.

[0059] Specifically, the switch structure 600 is installed on the material shifting seat 520, and the material shifting driver 540 drives the switch structure 600 to move left and right to cover or open the material drop hole 110. Specifically, the material shifting driver 540 drives the material shifting seat 520 and the switch structure 600 to move at the same time, and the switch structure 600 is directly installed on the material shifting seat 520. When the switch structure 600 moves to open the material drop hole 110, the capsule cover end clamping assembly 530 moves to the bottom of the material drop hole 110. Since the falling block 120 stops other capsule cups from sliding down, only one capsule cup can enter the extraction mechanism 500 through the material drop hole 110 at a time; when the capsule cover end clamping assembly 530 moves to other positions, the switch structure 600 blocks the material drop hole 110. The above structure enables the capsule extraction machine to complete the functions of material selection, material drop, extraction and waste discarding with only the material change driver and the material shifting driver 540, which significantly simplifies the structure of the capsule extraction machine, greatly reduces the manufacturing cost of the capsule extraction machine, and adapts to the miniaturization trend of the capsule extraction machine. It is conceivable that in other embodiments, the switch structure 600 may include a switch member and a separate switch driver, the switch driver drives the switch member to move to open or cover the blanking hole 110; or the switch driver drives the switch member to rotate to open or cover the blanking hole 110.

[0060] Specifically, the base 100 is equipped with a second capsule detector 700 for detecting whether there is a capsule cup in the extraction mechanism 500. The second capsule detector 700 may be a photoelectric sensor or a displacement sensor, for example, and those skilled in the art may configure the detector specifically according to actual needs.

[0061] Specifically, the working process of the extraction mechanism 500 is as follows: when the material transfer driver 540 drives the material transfer seat 520 and the switch structure 600 to move and open the material drop hole 110, the capsule cover end clamping assembly 530 moves to the bottom of the material drop hole 110, and the capsule cup on the storage rack 200 falls and is clamped and fixed by the capsule cover end clamping assembly 530, and then the material transfer seat 520 and the capsule cover end clamping assembly 530 move toward the limiting seat 510, and the switch structure 600 closes the material drop hole 110 again, and then the bottom end of the capsule cup is placed into the capsule bottom end receiving hole. During this period, the limiting seat 510 pushes the two clamping arms 532 to open, so that the cover end of the capsule cup passes over the capsule cover end clamping assembly 530 and enters the cover end limiting groove 550, and the material transfer seat 520 directly contacts and pushes the capsule cup to insert into the capsule bottom end receiving hole, and the first liquid passing needle and the second liquid passing needle 521 are inserted into the capsule cup. Then the second liquid needle 521 injects hot water into the capsule cup for extraction, and the first liquid needle receives the extracted liquid. After the extraction is completed, the material transfer seat 520 moves away from the limiting seat 510 and resets, and the capsule ejection structure ejects the capsule cup for a certain distance, so that the cover end of the capsule cup is always kept in the cover end limiting groove 550, and then the capsule cover end clamping assembly 530 is closed again and limits the left and right positions of the capsule cup, driving the capsule cup to completely detach from the limiting seat 510. After the capsule cup detaches from the capsule bottom receiving hole, the capsule cup can fall out of the extraction mechanism through the cup body clearance opening 533 and the notch of the cover end limiting groove 550 under the action of gravity, and be recovered.

[0062] Specifically, the control module is also electrically connected to the extraction mechanism 500 .

[0063] The capsule extraction machine disclosed in the utility model is particularly suitable for extracting raw materials such as coffee and tea, and multiple types of capsule cups can be placed on the storage rack 200 at the same time. It is understandable that other types of raw materials can also use the capsule extraction machine of the utility model.
