[0036] Please refer to Figure 1 , Figure 1 An embodiment of the present application provides a beverage machine 100, Figure 2 The brewing device 102 of the beverage machine 100 is shown.

[0037] The beverage machine 100 can brew the powder to obtain a beverage. In embodiments of the present application, the type of the powder and the type of the beverage are not limited. For example, the powder can be coffee powder obtained by grinding coffee beans, and the beverage can be coffee liquid obtained by brewing the coffee powder.

[0038] In embodiments of the present application, the beverage machine 100 can include a cabinet 101 and a brewing device 102. The brewing device 102 can be disposed in the cabinet 101 and fixedly connected with the cabinet 101. The brewing device 102 can contain the powder and access to the brewing liquid. The brewing liquid can brew the powder in the brewing device 102 to obtain a beverage. The beverage can flow out of the brewing device 102 and flow to outside of the cabinet 101, so that a user can receive the beverage from outside of the cabinet 101 by a container.

[0039] The way in which the brewing device 102 accesses the brewing liquid and the way in which the beverage in the brewing device 102 flows out of the brewing device 102 can be common in the related art, and will not be described here.

[0040] In embodiments of the present application, the type of the brewing liquid is not limited. For example, the brewing liquid can be, but is not limited to, water, milk or oat milk.

[0041] Please refer to Figure 3 In an embodiment, the brewing device 102 can include a brewing mechanism 10, a triggering mechanism 20, a moving piece 30 and a driving mechanism 40.

[0042] The brewing mechanism 10 can be provided with a feeding cavity 111 penetrating one end of the brewing mechanism 10 in the length direction. The powder can enter the feeding cavity 111 and be contained in the feeding cavity 111. The brewing liquid can access the feeding cavity 111 to brew the powder in the feeding cavity 111.

[0043] The moving piece 30 can be fixedly connected with one side of the brewing mechanism 10 in the width direction. The moving piece 30 can be fixedly connected with a triggering protrusion 31 on the side away from the brewing mechanism 10, and the triggering protrusion 31 extends in the direction away from the brewing mechanism 10. The driving mechanism 40 can be connected with the moving piece 30, and the driving mechanism 40 has a stator portion. The driving mechanism 40 can drive the moving piece 30 to move relative to the stator portion of the driving mechanism 40, so as to synchronously move the brewing mechanism 10.

[0044] Please refer to Figure 4 and Figure 5The trigger mechanism 20 can be located on the side of the moving member 30 away from the brewing mechanism 10. The trigger mechanism 20 can include a connecting assembly 21 and a first trigger assembly 22. The connecting assembly 21 can be relatively fixed with the stator part of the driving mechanism 40 and is spaced apart from the stator part of the driving mechanism 40. The connecting assembly 21 is located on both sides of the stator part of the driving mechanism 40, respectively, with the brewing mechanism 10. The first trigger assembly 22 can include a first trigger member 221 and a first switch 222. The first switch 222 is a normally open switch, and the closure of the first switch 222 can be achieved by contacting or pressing the first switch 222. The first switch 222 can be fixedly installed on the side of the connecting assembly 21 away from the brewing mechanism 10.

[0045] Please refer to Figure 6 and Figure 7 The first trigger member 221 can include a cam 2211, a first connecting shaft 2212, and a first protrusion 2213. The cam 2211 can be located on the side of the connecting assembly 21 away from the brewing mechanism 10. The first connecting shaft 2212 is fixedly connected with the first cam 2211, and the first connecting shaft 2212 is arranged through the connecting assembly 21 in the opposite direction of the trigger mechanism 20 and the brewing mechanism 10; the first connecting shaft 2212 is rotatably connected to the connecting assembly 21, so that the cam 2211 can rotate relative to the connecting assembly 21. The first protrusion 2213 is fixedly connected to the peripheral wall of the first connecting shaft 2212, so as to realize the connection between the first protrusion 2213 and the cam 2211. The first protrusion 2213 is located on the side of the first connecting shaft 2212 away from the cam 2211. The first protrusion 2213 is used to abut against the trigger protrusion 31, and when the driving mechanism 40 drives the moving member 30 to move, the trigger protrusion 31 can approach the first protrusion 2213, and then the trigger protrusion 31 can abut against the first protrusion 2213 and push the first protrusion 2213 to rotate, so as to synchronously rotate the cam 2211 and the first connecting shaft 2212.

[0046] The peripheral wall of the cam 2211 can include a first arc segment 2211A and a second arc segment 2211B. The second arc segment 2211B and the first arc segment 2211A are sequentially arranged in the first circumferential direction. The distance between the first arc segment 2211A and the center of the cam 2211 is less than the distance between the second arc segment 2211B and the center of the cam 2211, that is, the distance between the first arc segment 2211A and the center of the cross section of the cam 2211 is less than the distance between the second arc segment 2211B and the center of the cross section of the cam 2211. The first switch 222 can include a movable part 2221, which can rotate or can elastically deform, and the movable part 2221 abuts against the peripheral wall of the cam 2211. As shown in Figure 4 When the movable part 2221 abuts against the first arc segment 2211A, the first switch 222 is not triggered, and the first switch 222 remains in an open state; as shown in Figure 5As shown, when the movable part 2221 comes into contact with the second arc surface segment 2211B, the first switch 222 is triggered and the first switch 222 is closed.

[0047] Among them, such as Figure 2 As shown, the brewing device 102 is provided with a first position 1021 and a second position 1022. The first position 1021 and the second position 1022 can be located at both ends of the stator portion of the drive mechanism 40, respectively. When the drive mechanism 40 drives the brewing mechanism 10 to move from the first position 1021 to the second position 1022, the trigger protrusion 31 can abut against the first protrusion 2213 during the movement, and push the first protrusion 2213 to rotate along the first circumferential direction, so that the cam 2211 rotates along the first circumferential direction. At this time, the movable part 2221 abuts against the first arc surface segment 2211A, and as the first arc surface segment 2211A rotates, the movable part 2221 gradually moves away from the second arc surface segment 2211B, so that when the brewing mechanism 10 moves from the first position 1021 to the second position 1022, the movable part 2221 can remain in contact with the first arc surface segment 2211A, so that the first switch 222 remains open.

[0048] When the drive mechanism 40 drives the brewing mechanism 10 to move from the second position 1022 to the first position 1021, the trigger protrusion 31 can abut against the first protrusion 2213 during the movement and push the first protrusion 2213 to rotate along the second circumferential direction, causing the cam 2211 to rotate along the second circumferential direction. At this time, the movable part 2221 that abuts against the first arc surface segment 2211A gradually approaches the second arc surface segment 2211B as the first arc surface segment 2211A rotates, and finally disengages from the first arc surface segment 2211A and abuts against the second arc surface segment 2211B. The second arc surface segment 2211B can cause the movable part 2221 to move away from the center of the cam 2211, so that the movable part 2221 rotates or undergoes elastic deformation, thereby closing the first switch 222. Thus, when the brewing mechanism 10 moves from the second position 1022 to the first position 1021, the movable part 2221 can separate from the first arc surface segment 2211A and abut against the second arc surface segment 2211B, thereby closing the first switch 222. The component connected to the first switch 222 can work or stop in response to the closing of the first switch 222.

[0049] It can be understood that the trigger protrusion 31 rotates by pushing the first protrusion 2213, and the cam 2211 rotates synchronously, so that the movable part 2221 can be separated from the first arc segment 2211A and abut against the second arc segment 2211B. Since the distance between the second arc segment 2211B and the center of the cam 2211 is greater than the distance between the first arc segment 2211A and the center of the cam 2211, the second arc segment 2211B can press the movable part 2221 to rotate or deform, so that the first switch 222 is closed. Since the difference between the distance between the first arc segment 2211A and the center of the cam 2211 and the distance between the second arc segment 2211B and the center of the cam 2211 is fixed, when the movable part 2221 is separated from the first arc segment 2211A and abuts against the second arc segment 2211B, the distance of deformation or movement of the movable part 2221 can be fixed, so that the distance of deformation or movement of the movable part 2221 is not affected by the size error of the trigger protrusion 31.

[0050] Compared with the case in the related art that the corresponding switch element is directly pressed by the trigger protrusion 31 to close the switch element, in the embodiment of the present application, the trigger protrusion 31 rotates the cam 2211 to make the second arc segment 2211B on the cam 2211 abut against the movable part 2221 to trigger the first switch 222 to close, which can avoid the case that the first switch 222 is excessively pressed by the trigger protrusion 31 with a size error, and can reduce the probability that the first switch 222 is damaged due to excessive pressing or the movable part 2221 cannot be reset. In this way, the service life of the first switch 222 can be increased, and the failure rate of the brewing device 102 can be reduced.

[0051] In the embodiment of the present application, the type of the first switch 222 is not specifically limited. For example, the first switch 222 can be, but is not limited to, a micro switch or a travel switch.

[0052] For example, the first switch 222 can be a micro switch, the body of the first switch 222 can be fixedly installed on the connecting assembly 21, and the movable part 2221 of the first switch 222 can include a trigger spring of the micro switch and a roller rotatably connected to the trigger spring, wherein the roller can abut against the first arc segment 2211A and the second arc segment 2211B. When the cam 2211 rotates in the second circumferential direction to separate the roller from the first arc segment 2211A and abut against the second arc segment 2211B, the cam 2211 pushes the roller to be close to the body of the first switch 222, so that the trigger spring moves synchronously and presses a trigger button on the body of the first switch 222, and the first switch 222 is closed. When the cam 2211 rotates in the first horizontal direction to separate the roller from the second arc segment 2211B, the trigger spring can restore to the original state under the action of its own elastic force, and the roller can be reset to abut against the first arc segment 2211A.

[0053] It can be understood that the first circumferential direction and the second circumferential direction can be circumferential directions opposite to each other. In embodiments of the present application, the first circumferential direction and the second circumferential direction are not specifically limited. For example, the first circumferential direction is a clockwise direction CW as shown in Figure 4 and Figure 5 The second circumferential direction is a counterclockwise direction CCW as shown in Figure 4 and Figure 5 .

[0054] In embodiments of the present application, the fixing manner when fixedly connecting and fixedly mounting is not specifically limited. For example, the fixing manner can include, but is not limited to, bolt fixing, screw fixing, welding fixing, integral forming fixing, and buckle fixing.

[0055] It can be understood that the rotatable connection can be a connection manner that can cause relative rotation of two components by a rotating connecting shaft. In embodiments of the present application, the type of the rotating connecting shaft is not specifically limited. For example, the rotating connecting shaft can be, but is not limited to, a bearing, a pin shaft, or a hinge.

[0056] In some embodiments, the first triggering assembly 22 can further include an elastic reset member 223. One end of the elastic reset member 223 is fixedly connected with the cam 2211, and the other end is fixedly connected with the cam 2211. In the process of moving the brewing mechanism 10 and the moving member 30, when the triggering protrusion 31 pushes the cam 2211 to rotate, the elastic reset member 223 is stretched to cause elastic deformation; after the brewing mechanism 10 and the moving member 30 continue to move, the triggering protrusion 31 is separated from the first protrusion 2213, at this time, the elastic reset member 223 can restore to the original state under the action of its own elastic force, and drive the cam 2211 to rotate to the initial angle.

[0057] It can be understood that after the first protrusion 2213 is separated from the triggering protrusion 31, the cam 2211 can be driven to restore to the initial angle under the elastic force of the elastic reset member 223, so that the first protrusion 2213 is reset, and when the triggering protrusion 31 moves again, the first protrusion 2213 can be abutted again and drive the cam 2211 to rotate again. In this way, the first triggering assembly 22 can realize the reset function through the elastic reset member 223, so that the first triggering member 221 can be automatically reset in the process of multiple operations of the triggering mechanism 20, to cooperate with the brewing mechanism 10 to realize multiple movements.

[0058] In embodiments of the present application, the type of the elastic reset member 223 is not specifically limited. For example, the elastic reset member 223 can be, but is not limited to, a tension spring.

[0059] In some embodiments, the brewing device 102 can further comprise a powder pressing piston 50, which can be fixedly connected to the stator portion of the driving mechanism 40 and located at the second position 1022. The powder pressing piston 50 is located at the same side of the driving mechanism 40 as the brewing mechanism 10. When the brewing mechanism 10 moves to the second position 1022, the powder pressing piston 50 can enter the feeding cavity 111 and press the powder in the feeding cavity 111 in cooperation with the bottom wall of the feeding cavity 111, so as to compact the powder and facilitate the brewing of the powder by the brewing liquid.

[0060] Please refer to Figure 8 In some embodiments, the driving mechanism 40 can comprise a guide frame 41, a fixed seat 42, a lead screw 43 and a moving driving member 44. The guide frame 41 is the stator portion of the driving mechanism 40. The brewing mechanism 10 and the powder pressing piston 50 are located at the same side of the guide frame 41, and the connecting assembly 21 is located at the other side of the brewing device 102. The powder pressing piston 50 is fixedly connected to the guide frame 41, and the connecting assembly 21 is fixedly connected to the guide frame 41. The guide frame 41 is provided with a first guide slot 411, which penetrates the guide frame 41 along the relative direction of the brewing mechanism 10 and the connecting assembly 21. The two ends of the first guide slot 411 are located between the first position 1021 and the second position 1022 and extend towards the first position 1021 and the second position 1022, respectively. The side of the moving member 30 facing the brewing mechanism 10 is fixedly connected with a connecting head 32, which is fixedly connected to the brewing mechanism 10. The connecting head 32 can be in the form of a roller. The connecting head 32 penetrates the first guide slot 411 and is slidingly connected to the first guide slot 411 along the extension direction of the first guide slot 411. The moving member 30 is fixedly connected to the connecting head 32, which is located at the side of the guide frame 41 away from the brewing mechanism 10.

[0061] The fixed seat 42 is fixedly installed at the side of the guide frame 41 away from the brewing mechanism 10. The lead screw 43 is rotatably connected to the fixed seat 42. The moving member 30 is sleeved on the lead screw 43 and threadedly connected to the lead screw 43. The moving member 30 can slidingly cooperate with the guide frame 41 along the extension direction of the lead screw 43. The moving driving member 44 can be relatively fixed with the guide frame 41, and the moving driving member 44 can be connected with the lead screw 43. The moving driving member 44 can drive the lead screw 43 to rotate, thereby driving the brewing mechanism 10 and the moving member 30 to move synchronously, so that the brewing mechanism 10 can move along the first guide slot 411 from the first position 1021 to the second position 1022 and from the second position 1022 to the first position 1021.

[0062] In the embodiments of the present application, the type of the moving driving member 44 is not specifically limited. For example, the moving driving member 44 can be, but is not limited to, a motor.

[0063] In the embodiments of the present application, the connection between the moving driving member 44 and the lead screw 43 is not specifically limited. For example, the moving driving member 44 can be a motor, and the rotor of the moving driving member 44 can be coaxially fixed with the lead screw 43. For another example, the moving driving member 44 can be a click, and the rotor of the moving driving member 44 can be connected with the lead screw 43 through a gear set to indirectly achieve the connection between the moving driving member 44 and the lead screw 43.

[0064] In the embodiments of the present application, the relative fixation between the moving driving member 44 and the guide frame 41 is not specifically limited. For example, the side of the guide frame 41 away from the brewing mechanism 10 can be fixedly connected with a mounting frame, and the mounting frame can be fixedly connected with the moving driving member 44 to achieve the relative fixation between the moving driving member 44 and the guide frame 41.

[0065] It can be understood that the connecting assembly 21 can be fixedly connected with the mounting frame to achieve the relative fixation with the guide frame 41.

[0066] In the embodiments of the present application, the number of the fixed seats 42 is not specifically limited. For example, the number of the fixed seats 42 can be two, and the two fixed seats 42 can be spaced apart in the interval direction between the first position 1021 and the second position 1022, and the two ends of the lead screw 43 are respectively rotatably connected with the two fixed seats 42.

[0067] In some embodiments, the first guide slot 411 can include a first sub-slot 4111 and a second sub-slot 4112. The first sub-slot 4111 and the second sub-slot 4112 are communicated, the first position 1021 is located at one end of the first sub-slot 4111 away from the second sub-slot 4112, and the second position 1022 is located at one end of the second sub-slot 4112 away from the first sub-slot 4111. The extension direction of the first sub-slot 4111 and the extension direction of the second sub-slot 4112 form an obtuse angle.

[0068] The side of the brewing mechanism 10 facing the guide frame 41 is fixedly connected with a guide head 112, the guide head 112 can be cylindrical, and the guide head 112 penetrates the first guide slot 411. The guide head 112 and the connecting head 32 are spaced apart in the length direction of the brewing mechanism 10, and are located on the side of the connecting head 32 away from the second position 1022. The guide head 112 and the connecting head 32 can both be rotatably matched with the inner wall of the first guide slot 411.

[0069] It can be understood that the first sub-slot 4111 can extend along the vertical direction. When the brewing mechanism 10 is located at the first position 1021, the guide head 112 is located in the first sub-slot 4111, the connecting head 32 is located at the end of the first sub-slot 4111 communicated with the second sub-slot 4112, at this time, the line between the guide head 112 and the connecting head 32 coincides with the vertical direction, and at this time, the length direction of the brewing mechanism 10 coincides with the vertical direction.

[0070] When the driving mechanism 40 drives the brewing mechanism 10 to move to the second position 1022, the connecting head 32 moves along the second sub-groove 4112 to the second position 1022, and the guide head 112 moves along the extension direction of the first sub-groove 4111 to the end of the first sub-groove 4111 communicating with the second sub-groove 4112, at this time, the brewing mechanism 10 rotates from the vertical setting to the inclined setting, and the inclination angle gradually increases. When the guide head 112 moves from the first sub-groove 4111 to the second sub-groove 4112, at this time, the guide head 112 and the connecting head 32 are located in the second sub-groove 4112, the connection between the guide head 112 and the connecting head 32 coincides with the extension direction of the second sub-groove 4112, and at this time, the length direction of the brewing mechanism 10 coincides with the extension direction of the second sub-groove 4112.

[0071] The brewing mechanism 10 continues to move to the second position 1022. The extension direction of the powder compression piston 50 located at the second position 1022 coincides with the extension direction of the second sub-groove 4112. When the brewing mechanism 10 moves to the second position 1022, the powder compression piston 50 extends into the feeding chamber 111 along the extension direction of the second sub-groove 4112, and compacts the powder in the feeding chamber.

[0072] The extension direction of the screw rod 43 can coincide with the extension direction of the second sub-groove 4112, that is, both form an obtuse angle with the vertical direction. In this way, the rotation of the screw rod 43 can drive the connecting head 32 to rotate along the extension direction of the second sub-groove 4112, and under the cooperation of the first sub-groove 4111, the second sub-groove 4112 and the guide head 112, the brewing mechanism 10 can rotate in the process of moving synchronously with the connecting head 32, so that the opening of the feeding chamber 111 rotates from being away from the powder compression piston 50 to being towards the powder compression piston 50, and the powder compression piston 50 can enter the feeding chamber 111 to compact the powder.

[0073] It can be understood that when the driving mechanism 40 drives the brewing mechanism 10 to move from the second position 1022 to the first position 1021, the guide head 112 can move from the second sub-groove 4112 into the first sub-groove 4111, and move along the extension direction of the first sub-groove 4111 to the first position 1021, so that the inclination angle of the brewing mechanism 10 gradually decreases, and finally returns to the state that the length direction coincides with the vertical direction.

[0074] In the embodiments of the present application, the height direction of the beverage machine 100 can be defined as the vertical direction. For example, the vertical direction can be the Z direction shown in FIG. 1. Figure 8

[0075] ​It can be understood that when the brewing mechanism 10 is located at the first position 1021, the opening of the feeding cavity 111 of the brewing mechanism 10 can be vertically upwardly arranged, and a feeding device (not shown in the figure) in the beverage machine 100 adds powder into the feeding cavity 111. Then, the driving mechanism 40 can drive the brewing mechanism 10 to move from the first position 1021 to the second position 1022, so that the powder compaction piston 50 can compact the powder in the feeding cavity 111 to improve the flavor of the brewed beverage.

[0076] When the powder compaction piston 50 enters the feeding cavity 111 to compact the powder, the brewing liquid can be introduced into the feeding cavity 111 through the joint arranged on the powder compaction piston 50 to brew the powder to generate the beverage. The beverage can flow out of the feeding cavity 111 through the export channel (not shown in the figure) arranged in the feeding cavity 111, or be sucked out of the feeding cavity 111 through the suction nozzle (not shown in the figure) in communication with the feeding cavity 111.

[0077] Please refer to Figure 9 and Figure 10 In some embodiments, the brewing mechanism 10 can include a housing 11 and a piston assembly 12. The feeding cavity 111 can be arranged on one side of the housing 11 in the length direction, and the connecting head 32 and the guide head 112 can be fixedly connected to one side of the housing 11 facing the guide frame 41. As shown in Figure 2 and Figure 10 The side of the housing 11 facing the guide frame 41 can also be provided with a second guide groove 113 extending along the length direction of the brewing mechanism 10. When the connecting head 32 and the guide head 112 are located in the second sub-groove 4112, the extension direction of the second guide groove 113 is the same as that of the second sub-groove 4112.

[0078] The piston assembly 12 can include a piston head 121 and a connecting frame 122. The piston head 121 can be movably connected to the feeding cavity 111 in the length direction of the brewing mechanism 10, and the piston head 121 can close the feeding cavity 111 from one side to cooperate with the bottom wall of the feeding cavity 111. The piston head 121 is used to receive the powder and the powder residue formed after the powder is brewed. The connecting frame 122 can be located on the side of the piston head 121 away from the opening of the feeding cavity 111 and fixedly connected with the piston head 121. One side of the connecting frame 122 is fixedly connected with a plug-in piece 123 extending in the opposite direction of the brewing mechanism 10 and the trigger mechanism 20 and penetrating the second guide groove 113. The plug-in piece 123 is slidably connected with the second guide groove 113 in the length direction of the brewing mechanism 10. The side of the plug-in piece 123 facing the guide frame 41 can be provided with a plug-in groove 1231. The connecting frame 122 can move relative to the housing 11 in the length direction of the brewing mechanism 10, and the plug-in piece 123 can move synchronously in the second guide groove 113 in the same direction.

[0079] The brewing device 102 can further comprise a plug-in mechanism 60. The plug-in mechanism 60 can comprise a plug-in rod 61 and a plug-in driving member 62. The plug-in driving member 62 can be fixedly installed on the side of the connecting assembly 21 away from the guide frame 41, and the plug-in rod 61 can be fixedly connected with the plug-in driving member 62. The plug-in rod 61 can extend in the direction opposite to the brewing mechanism 10 and the trigger mechanism 20, and can move along the extending direction thereof to be close to and plugged into the plug-in slot 1231, and to move out of and away from the plug-in slot 1231. The plug-in driving member 62 can drive the plug-in rod 61 to move along the extending direction thereof.

[0080] It can be understood that when the brewing device 102 completes the brewing of the powder to form the powder residue, the driving mechanism 40 can drive the brewing mechanism 10 to move from the second position 1022 to the first position 1021. As shown in Figure 9 , in the process of moving of the brewing mechanism 10, the plug-in driving member 62 can drive the plug-in rod 61 to move, so that the plug-in rod 61 is plugged into the plug-in slot 1231; as shown in Figure 10 , at this time, the driving mechanism 40 continues to drive the moving member 30 to move, and the casing 11 fixedly connected with the moving member 30 can move synchronously, while the movement of the piston assembly 12 is hindered by the plug-in rod 61, so that the piston assembly 12 moves relatively with the casing 11, thereby the piston head 121 gradually approaches the opening of the feeding cavity 111 on the casing 11, and the piston head 121 can synchronously push the powder residue received thereby to approach the opening on the casing 11. When the piston head 121 moves to the opening of the feeding cavity 111 on the casing 11, all the powder residue received by the piston head 121 can be located outside the feeding cavity 111.

[0081] As shown in Figure 3 and Figure 6 , the casing 11 can be provided with a push rod 114 located on the side of the casing 11 on which the feeding cavity 111 is opened. The push rod 114 is rotatably connected with the casing 11, and a torsion spring (not shown in the figure) is connected between the push rod 114 and the casing 11. When the driving mechanism 40 drives the casing 11 to approach the first position 1021, the push rod 114 can abut against a push block (not shown in the figure) provided in the machine box 101, and the push block can push the push rod 114 to rotate along with the movement of the casing 11 and the push rod 114. The push rod 114 can push the powder residue to move by rotating, so that the powder residue located outside the feeding cavity 111 can be swept away from the brewing mechanism 10, and the powder residue can fall into a collecting member (not shown in the figure) pre-provided in the machine box 101.

[0082] Then, the plug driving member 62 can drive the plug rod 61 to reset to move out of the plug slot 1231, at this time, the driving mechanism 40 can drive the machine shell 11 to move towards the second position 1022, so that the brewing mechanism 10 can be close to the powder piston 50 again, the powder piston 50 can abut against the piston head 121 and push the piston head 121 into the machine shell 11, so that the connecting frame 122 moves synchronously, and the plug 123 moves synchronously along the second guide slot 113. When the brewing mechanism 10 moves to the second position 1022, the movement of the piston head 121 pushed by the powder piston 50 can form the feeding cavity 111 in the machine shell 11 again, and the powder piston 50 enters the feeding cavity 111. During the movement of the brewing mechanism 10 to the second position 1022, the push rod 114 can be separated from the push block, and rotate to the initial angle under the elastic force of the torsional spring, so that the push rod 114 avoids the feeding cavity 111.

[0083] It can be understood that after the piston head 121 is pushed into the machine shell 11 by the powder piston 50, the driving mechanism 40 can drive the brewing mechanism 10 to move to the first position 1021 again, so that the brewing mechanism 10 moves to the first position 1021 and stops moving, to wait for the feeding of the powder in the feeding cavity 111.

[0084] After the powder is fed, the brewing device 102 can again sequentially perform the following work flow: the driving mechanism 40 drives the brewing mechanism 10 to move to the second position 1022 for the first time to make the powder piston 50 compact the powder, waits for the brewing of the powder to produce the beverage and the beverage to flow out of the brewing mechanism 10; the driving mechanism 40 drives the brewing mechanism 10 to move to the first position 1021; the plug driving member 62 drives the plug rod 61 to plug into the plug slot 1231; the driving mechanism 40 continues to drive the machine shell 11 to move close to the first position 1021, so that the piston assembly 12 moves relative to the machine shell 11, the piston head 121 pushes the powder residue out of the machine shell 11, and the push rod 114 rotates to sweep the powder residue off the machine shell 11; the plug driving member 62 drives the plug rod 61 to move out of the plug slot 1231; the driving mechanism 40 drives the brewing mechanism 10 to move to the second position 1022 for the second time to make the powder piston 50 abut against the piston head 121, and pushes the piston head 121 into the machine shell 11 to form the feeding cavity 111 in the machine shell 11 again; the driving mechanism 40 drives the brewing mechanism 10 to move to the first position 1021 to wait for the feeding of the powder.

[0085] In this way, the brewing device 102 can realize the brewing of the beverage and the cleaning of the powder residue once for each execution of the work flow, and can reset to the first position 1021 after each execution of the work flow to wait for the start of the next work flow, so that the beverage machine 100 can realize the automatic brewing of the beverage.

[0086] In the embodiments of this application, the positional relationship between the insertion rod 61 and the guide frame 41 is not specifically limited. For example, in the extension direction perpendicular to the extension direction of the insertion rod 61 and the extension direction of the second sub-slot 4112, that is, in the width direction of the guide frame 41, the insertion rod 61 can be spaced apart from the guide frame 41; when the insertion rod 61 is inserted into the slot 1231, it can avoid the guide frame 41.

[0087] For example, a socket 412 can be provided on the guide frame 41. The socket 412 can pass through the guide frame 41 along the extension direction of the insertion rod 61 and can be set corresponding to the insertion rod 61. The socket 412 can be spaced apart from the first guide groove 411. The insertion rod 61 can be inserted into the slot 1231 after passing through the socket 412.

[0088] In the embodiments of this application, the number of insertion rods 61 is not specifically limited. For example, the number of insertion rods 61 can be two. The two insertion rods 61 can be spaced apart in the direction perpendicular to the extension direction of the insertion rods 61 and the extension direction of the second sub-slots 4112, that is, in the width direction of the guide frame 41. The insertion drive member 62 can be fixedly connected to the two insertion rods 61 and can drive the two insertion rods 61 to be inserted into or removed from the slots 1231 simultaneously; the number of insertion members 123, the number of slots 1231, and the number of second guide slots 113 can all be two, with two slots 1231 corresponding one-to-one with two insertion rods 61, and two insertion members 123 corresponding one-to-one with two second guide slots 113.

[0089] In the embodiments of this application, the type of the plug-in drive 62 is not specifically limited. For example, the plug rod 61 can be made of ferromagnetic material, and the plug-in drive 62 can be, but is not limited to, an electromagnet.

[0090] In some embodiments, such as Figure 4 and Figure 5 As shown, the connecting assembly 21 may include a first connecting seat 211 and a second connecting seat 212, which may be arranged along the extending direction of the second sub-slot 4112. The first connecting seat 211 and the second connecting seat 212 may be fixedly connected. In the extending direction of the second sub-slot 4112, the first connecting seat 211 may be located on the side of the second connecting seat 212 closer to the first position 1021. The plug-in drive 62 may be fixedly mounted on the first connecting seat 211, and the plug rod 61 may be disposed to avoid the first connecting seat 211. The first switch 222 may be fixedly mounted on the second connecting seat 212, and the first connecting shaft 2212 may pass through the second connecting seat 212 and be rotatably connected to the second connecting seat 212.

[0091] In some embodiments, the number of the first trigger assemblies 22 can be two, and the two first trigger assemblies 22 can be arranged at intervals in the extending direction of the second sub-groove 4112. Each of the first assemblies comprises a first switch 222, a first trigger 221 and an elastic reset member 223. As shown in Figure 2 and Figure 8 The brewing device 102 can further comprise a third position 1023 and a fourth position 1024, both of which are located between the first position 1021 and the second position 1022 and are arranged on the guide frame 41. The third position 1023 is located between the fourth position 1024 and the second position 1022. The two first trigger assemblies 22 correspond to the third position 1023 and the fourth position 1024 respectively. During the movement of the brewing mechanism 10 from the second position 1022 to the first position 1021, when the brewing mechanism 10 moves to the third position 1023 and the fourth position 1024, the trigger protrusion 31 can abut against the corresponding first protrusion 2213 and trigger the corresponding first switch 222 to close.

[0092] Please refer to Figure 11 , the beverage machine 100 can further comprise a processor 103. The processor 103 can be in communication connection with the two first switches 222 and can be in communication connection with the movement driving member 44 and the plug driving member 62. After the powder is added in the feeding cavity 111, the processor 103 can control the movement driving member 44 to operate, so that the brewing mechanism 10 moves away from the first position 1021 and moves to the second position 1022 for the first time, and the powder compacting piston 50 compacts the powder. Then the processor 103 can control the movement driving member 44 to operate reversely, so that the brewing mechanism 10 approaches the first position 1021.

[0093] As shown in Figure 5 , when it is determined that the first switch 222 corresponding to the third position 1023 is closed, the processor 103 can control the movement driving member 44 to stop operating and control the plug driving member 62 to work, so that the plug driving member 62 drives the plug rod 61 to be plugged into the plug groove 1231, and then the processor 103 can control the movement driving member 44 to continue operating reversely.

[0094] When the first switch 222 corresponding to the fourth position 1024 is determined to be closed, the processor 103 can control the movement driving member 44 to stop running, and control the plug driving member 62 to work, so that the plug driving member 62 drives the plug rod 61 to move out of the insertion slot 1231 and reset, and then the processor 103 can control the movement driving member 44 to run, and the movement driving member 44 can drive the brewing mechanism 10 to move to the second position 1022 for the second time, so that the powder piston 50 pushes the piston head 121 into the shell 11. Then the processor 103 can control the movement driving member 44 to run reversely again, and the movement driving member 44 can drive the brewing mechanism 10 to reset to the first position 1021.

[0095] In the embodiments of the present application, the manner of the communication connection is not specifically limited. For example, the manner of the communication connection can be wired communication connection realized through a circuit or a signal line. For another example, the communication connection can be wireless communication connection realized through 3G, 4G, 5G, Bluetooth, radio frequency signal, wireless local area network or cellular network and the like.

[0096] It can be understood that when the first switch 222 is closed, a level change can be generated on the circuit connected between the processor 103 and the first switch 222, and the processor 103 can monitor the level change on the circuit and determine whether the first switch 222 is closed according to the level change. The principle of the processor 103 monitoring the level change is a general principle in the related field, which will not be described here.

[0097] It can be understood that after the brewing mechanism 10 moves to the second position 1022 for the second time, the processor 103 can stop responding to the closure of the two first switches 222 until the brewing mechanism 10 moves to the first position 1021, and the processor 103 can continue to respond to the closure of the two first switches 222. In this way, it can be avoided that the plug mechanism 60 is plugged into the insertion slot 1231 again after the brewing mechanism 10 completes the cleaning of the powder residue and the resetting of the piston head 121, and it can be avoided that the brewing mechanism 10 repeatedly executes the related work flow of the cleaning of the powder residue and the resetting of the piston head 121.

[0098] In the embodiments of the present application, the manner in which the processor 103 stops responding to the closure of the two first switches 222 is not specifically limited. For example, the processor 103 can stop detecting the level of the circuit in which the two first switches 222 are located. For another example, the processor 103 can ignore the closure of the current first switch 222 after detecting the closure of the first switch 222 once, and respond to the closure of the first switch 222 again after the next closure of the first switch 222.

[0099] In some embodiments, the triggering mechanism 20 may further include two second triggering components 24. The two second triggering components 24 are respectively located on both sides of the two first triggering components 22, and the two second triggering components 24 correspond to the first position 1021 and the second position 1022 respectively.

[0100] like Figure 4 and Figure 6 As shown, each second trigger component 24 may include a second switch 241 and a second trigger element 242. Each second switch 241 is communicatively connected to the processor 103. Both second switches 241 are fixedly mounted on the side of the connecting component 21 away from the guide frame 41. The second switch 241 corresponding to the first position 1021 is located at the end of the connecting component 21 near the first position 1021 and on the side of the plug-in drive element 62 away from the two first switches 222; the second switch 241 corresponding to the second position 1022 is located at the end of the connecting component 21 near the second position 1022.

[0101] Each second trigger 242 may include a point contact 2421, a second connecting shaft 2422, and a second protrusion 2423. Each point contact 2421 may be located on the side of the connecting assembly 21 opposite to the guide frame 41. Each second connecting shaft 2422 may pass through the connecting assembly 21 along the opposite direction of the connecting assembly 21 and the brewing mechanism 10, and be rotatably connected to the connecting assembly 21. Each second protrusion 2423 may be fixedly connected to the peripheral wall of the corresponding second connecting shaft 2422, and is located on the side of the second connecting shaft 2422 closer to the guide frame 41. Each second protrusion 2423 is used to abut against the trigger protrusion 31. The trigger protrusion 31 can push the second protrusion 2423 to rotate, thereby causing the second connecting shaft 2422 and the point contact 2421 to rotate synchronously. The rotation of the point contact 2421 can abut against and press the corresponding second switch 241, causing the corresponding second switch 241 to close.

[0102] It is understood that the type of the second switch 241 is the same as or similar to that of the first switch 222, and the way in which the second switch 241 is closed and reset is the same as or similar to the direction in which the first switch 222 is closed and reset, which will not be elaborated here.

[0103] It is understandable that the principle by which the second protrusion 2423 abuts against the trigger protrusion 31 and causes the second trigger 242 to rotate is the same as or similar to the principle by which the first protrusion 2213 abuts against the trigger protrusion 31 and causes the cam 2211 to rotate, and will not be elaborated here.

[0104] It can be understood that when the brewing mechanism 10 moves towards the second position 1022, the processor 103 can control the driving mechanism 40 to stop operating after determining that the second switch 241 corresponding to the second position 1022 is closed, so as to stop the movement of the brewing mechanism 10. When the brewing mechanism 10 moves towards the first position 1021, the processor 103 can control the driving mechanism 40 to stop operating after determining that the second switch 241 corresponding to the first position 1021 is closed, so as to stop the movement of the brewing mechanism 10.

[0105] It can be understood that the processor 103 determines whether the second switch 241 is closed in the same or similar manner as the processor 103 determines whether the first switch 222 is closed, which will not be described here.

[0106] It can be understood that when the brewing mechanism 10 is located at the first position 1021 and stops moving, the trigger protrusion 31 can keep abutting against the corresponding second protrusion 2423, and the corresponding second switch 241 can keep closed. After the processor 103 determines that the second switch 241 corresponding to the first position 1021 is closed, the beverage machine 100 can add powder to the powder cavity 111, and then the processor 103 can control the movement driving member 44 to operate to start the beverage production.

[0107] It can be understood that if the processor 103 determines that the second switch 241 corresponding to the first position 1021 is still open when the powder needs to be added to the powder cavity 111, the processor 103 can control the brewing device 102 to perform a reset process. The content of the reset process can be similar to the working process of the brewing device 102, and the difference is that the powder is not added to the brewing device 102 performing the reset process, and the powder is not brewed. After the reset process is completed, the brewing mechanism 10 can be reset to the first position 1021, and the processor 103 can determine that the second switch 241 corresponding to the first position 1021 is closed. The beverage machine 100 can add powder to the powder cavity 111.

[0108] It can be understood that the second trigger assembly 24 corresponding to the first position 1021 can be located on the first connecting seat 211, and the second trigger assembly 24 corresponding to the second position 1022 can be located on the second connecting seat 212.

[0109] In some cases, a torsional spring can be arranged between the second trigger 242 and the connecting assembly 21. After the second protrusion 2423 is separated from the trigger protrusion 31, the torsional spring can drive the second trigger 242 to rotate by its elastic force, so that the contact 2421 is separated from the second switch 241 and rotated to the initial angle.

[0110] In some other cases, after the second protrusion 2423 is separated from the trigger protrusion 31, the second protrusion 2423 can rotate to be arranged downward in the vertical direction under the action of gravity, so as to separate the point contact 2421 from the second switch 241 and rotate to the initial angle.

[0111] Please refer to Figures 12 to 15 , the following detailed working process of the brewing device 102 of the beverage machine 100:

[0112] As shown in Figure 5 and Figure 12 , when the brewing mechanism 10 can be located at the first position 1021, the trigger protrusion 31 is in abutment with the second protrusion 2423 corresponding to the first position 1021, and the second switch 241 corresponding to the first position 1021 is kept closed. After the powder is added into the feeding cavity 111, the processor 103 can control the movement driver 44 to operate, and the movement driver 44 drives the screw rod 43 to rotate, so as to make the brewing mechanism 10 move to the second position 1022 for the first time, and make the powder pressing piston 50 enter the feeding cavity 111 and compact the powder in the feeding cavity 111.

[0113] As shown in Figure 13 , when the brewing mechanism 10 moves to the second position 1022, the trigger protrusion 31 is in abutment with the second protrusion 2423 corresponding to the second position 1022, and pushes the corresponding second trigger 242 to rotate, so as to make the point contact 2421 press the corresponding second switch 241; the processor 103 determines that the second switch 241 corresponding to the second position 1022 is closed, and can control the movement driver 44 to stop operating to stop the movement of the brewing mechanism 10. Then the beverage machine 100 can input the brewing liquid into the feeding cavity 111 to generate the beverage by brewing the powder; the generated beverage can flow out of the brewing mechanism 10, and the powder forms powder residue after being brewed.

[0114] In the process that the brewing mechanism 10 moves from the first position 1021 to the second position 1022, the movement member 30 moves synchronously, the trigger protrusion 31 is separated from the second protrusion 2423 corresponding to the first position 1021, and the corresponding second switch 241 is disconnected; the trigger protrusion 31 sequentially abuts against the two first protrusions 2213 and pushes the two first protrusions 2213 to rotate, so as to make the two cams 2211 rotate in the first circumferential direction in sequence, and make the two movable parts 2221 keep in abutment with the corresponding first arc segment 2211A, and the two first switches 222 keep disconnected.

[0115] After the beverage is made, the processor 103 can control the moving driver 44 to operate reversely, the moving driver 44 drives the screw rod 43 to rotate reversely, so that the brewing mechanism 10 moves towards the first position 1021; the trigger protrusion 31 can be separated from the second protrusion 2423 corresponding to the second position 1022 during the movement, so as to disconnect the corresponding second switch 241.

[0116] As shown in FIG. 10, when the brewing mechanism 10 moves to the third position 1023, the trigger protrusion 31 abuts against the corresponding first protrusion 2213 and pushes the corresponding first protrusion 2213 to rotate, so that the corresponding cam 2211 rotates in the second circumferential direction, the movable part 2221 of the corresponding first switch 222 is separated from the first arc segment 2211A and abuts against the second arc segment 2211B, so that the first switch 222 corresponding to the third position 1023 is closed. Figure 5

[0117] As shown in FIG. 10, when the brewing mechanism 10 moves to the third position 1023, the trigger protrusion 31 abuts against the corresponding first protrusion 2213 and pushes the corresponding first protrusion 2213 to rotate, so that the corresponding cam 2211 rotates in the second circumferential direction, the movable part 2221 of the corresponding first switch 222 is separated from the first arc segment 2211A and abuts against the second arc segment 2211B, so that the first switch 222 corresponding to the third position 1023 is closed. Figure 9 Figure 14 As shown in FIG. 10, when the brewing mechanism 10 moves to the third position 1023, the trigger protrusion 31 abuts against the corresponding first protrusion 2213 and pushes the corresponding first protrusion 2213 to rotate, so that the corresponding cam 2211 rotates in the second circumferential direction, the movable part 2221 of the corresponding first switch 222 is separated from the first arc segment 2211A and abuts against the second arc segment 2211B, so that the first switch 222 corresponding to the third position 1023 is closed.

[0118] As shown in FIG. 10, when the brewing mechanism 10 moves to the third position 1023, the trigger protrusion 31 abuts against the corresponding first protrusion 2213 and pushes the corresponding first protrusion 2213 to rotate, so that the corresponding cam 2211 rotates in the second circumferential direction, the movable part 2221 of the corresponding first switch 222 is separated from the first arc segment 2211A and abuts against the second arc segment 2211B, so that the first switch 222 corresponding to the third position 1023 is closed.

[0119] As shown in FIG. 10, when the brewing mechanism 10 moves to the third position 1023, the trigger protrusion 31 abuts against the corresponding first protrusion 2213 and pushes the corresponding first protrusion 2213 to rotate, so that the corresponding cam 2211 rotates in the second circumferential direction, the movable part 2221 of the corresponding first switch 222 is separated from the first arc segment 2211A and abuts against the second arc segment 2211B, so that the first switch 222 corresponding to the third position 1023 is closed. Figure 10 Figure 15 ​​​As shown, after determining that the first switch 222 corresponding to the fourth position 1024 is closed, the processor 103 can control the plunger driving member 62 to work, so that the plunger 61 is removed from the insertion slot 1231 and reset, and then the processor 103 can control the moving driving member 44 to work again, so that the brewing mechanism 10 is moved to the second position 1022 for the second time. During the process of moving the brewing mechanism 10 to the second position 1022 for the second time, the powder pressing piston 50 pushes the piston head 121 to move into the casing 11, and the trigger protrusion 31 is separated from the first protrusion 2213 corresponding to the fourth position 1024, and the first protrusion 2213 and the cam 2211 are rotated to the initial angle under the elastic force of the corresponding reset elastic member, so that the corresponding movable part 2221 is separated from the second arc segment 2211B and abuts against the first arc segment 2211A, so that the corresponding first switch 222 is opened.

[0120] Then, the processor 103 controls the moving driving member 44 to work in reverse, so that the brewing mechanism 10 is moved from the second position 1022 to the first position 1021, and the processor 103 does not respond to the closing of the two first switches 222 during this process. When the brewing mechanism 10 is moved to the first position 1021, the trigger protrusion 31 abuts against the second protrusion 2423 corresponding to the first position 1021, so that the second switch 241 corresponding to the first position 1021 is closed. The processor 103 can control the moving driving member 44 to stop working after determining that the second switch 241 corresponding to the first position 1021 is closed, and wait for the powder in the feeding cavity 111 to be fed.

[0121] It can be understood that after the beverage machine 100 is started, the processor 103 can control the brewing device 102 to perform a reset process once, and then the brewing device 102 can be used to cooperate with the beverage machine 100 to make beverages after receiving the powder.

[0122] It can be understood that the trigger protrusion 31 rotates the first protrusion 2213 by pushing, so that the cam 2211 is synchronously rotated, so that the movable part 2221 can be separated from the first arc segment 2211A and abut against the second arc segment 2211B, so that the second arc segment 2211B can press the movable part 2221, so that the movable part 2221 is rotated or deformed, so that the first switch 222 is closed. Since the distance between the first arc segment 2211A and the center of the cam 2211 and the distance between the second arc segment 2211B and the center of the cam 2211 are fixed, the distance that the movable part 2221 is deformed or moved when the movable part 2221 is separated from the first arc segment 2211A and abuts against the second arc segment 2211B can be fixed.

[0123] Therefore, compared with the case of directly pressing the corresponding switch element to make the switch element close by the trigger protrusion 31 in the related art, the trigger protrusion 31 in the embodiment of the present application rotates the cam 2211 by pushing, and the second arc segment 2211B on the cam 2211 abuts against the movable part 2221 to trigger the first switch 222 to close. In this way, the case that the trigger protrusion 31 with size error presses the first switch 222 too much can be avoided, and the probability that the first switch 222 is damaged or the movable part 2221 cannot be reset due to excessive pressing can be reduced. The service life of the first switch 222 can be increased, and the failure rate of the brewing device 102 can be reduced.

[0124] By arranging the first arc segment 2211A on the cam 2211, the cam 2211 can be rotated in the first circumferential direction without triggering the corresponding first switch 222 to close, and can be rotated in the second circumferential direction to trigger the corresponding first switch 222 to close. In this way, the probability of false triggering of the first switch 222 can be reduced, and the smoothness of the operation of the brewing device 102 can be improved.

[0125] Meanwhile, two second switches 241 are arranged in the brewing device 102 corresponding to the first position 1021 and the second position 1022, respectively, and two first switches 222 are arranged corresponding to the third position 1023 and the fourth position 1024, respectively. The processor 103 can determine the position of the brewing mechanism 10 according to the opening and closing of the two second switches 241 and the two first switches 222, and then determine the execution of the working process of the brewing device 102, and control the brewing device 102 to execute the next process according to the execution of the working process of the brewing device 102. In this way, the smoothness of the operation of the brewing device 102 can be improved.
