[0042] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0043] It should be understood that the terms used herein, such as "upper", "above", "lower", "below", etc., indicating spatial relative positions, are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0044] The powder distribution device in the specific embodiment of the utility model refers to Figures 1 to 6As shown, the powder dispensing device 100 includes a powder box 20 and a discharge component 50 and a driving mechanism 30 respectively connected to both sides of the powder box 20. The powder box 20 is used to store powder, such as milk powder, cocoa powder, etc. The discharge component 50 is arranged on one side of the powder box 20, and the discharge component 50 has a discharge port 51 connected to the powder box 20. The driving mechanism 30 is arranged on the other side of the powder box 20. A feeding mechanism 60 is arranged in the powder box 20. The feeding mechanism 60 can be at least partially arranged in the powder box. The driving mechanism 30 is used to drive the feeding mechanism 60 to transfer the powder in the powder box 20 to the discharge port 51, and the powder falls into the target receiving port through the discharge port 51. For example, the powder falls into the target receiving port under the action of gravity. The driving mechanism 30 may include a motor and a transmission structure driven by the motor, and the transmission structure, such as a gear set, is used to transmit the rotational power of the motor to the feeding mechanism 60. The feeding mechanism 60 may include a feeding screw, which can realize stable pushing of the powder. The target receiving port may be a mixing container for mixing powder materials, or a channel port for guiding powder materials to fall into the mixing container.

[0045] The discharge component 50 includes a cover 52, and the feeding mechanism 60 includes a feeding shaft 61. One end of the feeding shaft 61 is provided with an actuating member 35 protruding in the radial direction, and the actuating member 35 abuts against the cover 52 in the radial direction. The discharge component 50 has a powder discharge position and a powder discharge position. In the powder discharge position, the driving mechanism 30 controls the feeding shaft 61 to rotate in a first direction, the cover 52 is limited, and the actuating member 35 rotates relative to the cover 52 to keep the discharge port 51 in an open state; the driving mechanism 30 controls the feeding shaft 61 to rotate in a second direction opposite to the first direction by a preset angle, and the actuating member 35 drives the cover 52 to rotate until the discharge port 51 is in a closed state, so that the discharge component 50 is in a powder discharge position. The rotation of the feeding shaft 61 in the first direction can be the rotation direction during normal discharge. The discharge port 51 is in an open state, for example, the discharge port 51 corresponds to the target receiving port along the gravity direction; the discharge port 51 is in a closed state, for example, the discharge port 51 is staggered with the target receiving port along the gravity direction. The correspondence and staggering between the discharge port 51 and the target receiving port can be that the discharge port 51 is fixed relative to the target receiving port and can be controlled to be opened and closed, or the discharge port 51 can be controlled to move relative to the target receiving port to connect and disconnect with the target receiving port.

[0046] When powder material needs to be discharged, the driving mechanism 30 can be controlled to drive the feeding shaft 61 to rotate in the first direction, such as the motor rotates forward, and the discharge port 51 can discharge material normally; when powder material does not need to be discharged, the driving mechanism 30 can be controlled to drive the feeding shaft 61 to rotate in the second direction, such as the motor rotates reversely, and the discharge port 51 is staggered with the target receiving port. In this way, the discharge port 51 can be automatically opened or closed to reduce the waste of powder material, and the steam in the mixing container can be prevented from entering the material cover 52 and the powder box 20 from the discharge port 51, thereby playing a moisture-proof role, which can not only prevent a small amount of powder material from being damp and adhering to the discharge component 50, reduce the cleaning frequency and cost, and ensure the powder discharge efficiency, but also avoid affecting the quality of the powder material in the powder box 20 and ensure the taste of the drink. In addition, the material cover 52 is driven by the radially protruding actuator 35, and the discharge port 51 can be reliably opened and closed with a simple structure.

[0047] Furthermore, a matching ring 36 is provided between the material cover 52 and the feeding shaft 61, and the matching ring 36 is provided with a hollow groove 361, and the actuating member 35 passes through the hollow groove 361 and abuts against the material cover 52. The matching ring 36 and the hollow groove 361 are provided, and the actuating member 35 interferes with the inner wall of the hollow groove 361 so that the actuating member 35 can drive the material cover 52 to rotate, thereby ensuring the reliability of the actuating member 35 and the material cover 52 rotating together.

[0048] The wear resistance and structural strength of the matching ring 36 are greater than those of the material cover 52. The matching ring 36 can be made of metal, and the material cover 52 is constructed as a plastic part. The matching ring 36 and the material cover 52 are interference-fitted. On the one hand, the actuator 35 and the matching ring 36 are both made of metal, and the friction force is small when the two rotate relative to each other, which can ensure the stable rotation of the feed shaft 61 and reduce the workload of the driving mechanism 30. On the other hand, the matching ring 36 has better wear resistance, which can increase the service life of the actuator 35 and the matching ring 36 and reduce maintenance costs.

[0049] In particular, the mating ring 36 and the cover 52 are made of different materials.

[0050] In particular, the actuator 35 is constructed as a steel column or steel ball with a spherical surface, and the feed shaft 61 is provided with an opening 611, and the actuator 35 is partially accommodated in the opening 611. The opening 611 is also provided with an elastic member 34, and the elastic member 34 presses the actuator 35 in the direction toward the outside of the opening 611. When the material cover 52 is limited, the actuator 35 can overcome the interference force between it and the inner wall of the hollow groove 361 through the elastic member 34, so as to ensure the normal rotation of the feed shaft 61, and when the actuator 35 is located in the hollow groove 361, the spherical surface contacts the material cover 52, and the contact area can also be reduced, thereby slowing down the wear of the actuator 35 and the material cover 52. Of course, the actuator 35 itself can also be an integrated structure including a steel ball and an elastic member 34.

[0051] In addition, the material cover 52 is sleeved on the end of the feed shaft 61, and a sealing ring 62 is provided between the material cover 52 and the feed shaft 61. Along the axial direction of the feed shaft 61, the sealing ring 62 is located on the side of the actuator 35 away from the material cover 52, specifically, the sealing ring 62 is located on the inner side of the matching ring 36, that is, between the matching ring 36 and the feed shaft 61. The provision of the sealing ring 62 can prevent the powder from reaching the space between the actuator 35 and the matching ring 36, prevent the powder from filling the space, and avoid affecting the normal use of the actuator 35 and the matching ring 36.

[0052] Reference Figure 2 The material cover 52 is constructed as a sleeve and includes a first cylindrical portion 521 and a second cylindrical portion 522 in the axial direction. The diameter of the first cylindrical portion 521 is smaller than the diameter of the second cylindrical portion 522. The first cylindrical portion 521 is sleeved on the end of the feeding shaft 61. The second cylindrical portion 522 is provided with an opening 523. In the powder discharging position, the opening 523 overlaps with the discharging port 51; in the powder discharging position, the opening 523 is staggered with the discharging port 51 in the circumferential direction. The material cover 52 is equivalent to a hatch for opening and closing the discharging port 51. The hatch directly blocks the discharging port 51, which can more reliably prevent the powder from contacting with steam.

[0053] The discharge component 50 further includes a discharge guide 53, the discharge port 51 is provided on the discharge guide 53, the discharge guide 53 is sleeved on the outside of the material cover 52, and the discharge guide 53 is limited by the powder box 20 along the axial direction of the feed shaft 61. The clearance between the discharge guide 53 and the material cover 52 facilitates the installation of the two, and the axial displacement of the discharge guide 53 is limited by the powder box 20, so the structure is simple and reliable.

[0054] Furthermore, a protrusion 525 is provided on the circumference of the material cover 52, and a limiting groove 535 is provided on the inner wall of the material discharging guide 53. The cooperation between the protrusion 525 and the limiting groove 535 limits the rotation range of the material cover 52 relative to the material discharging guide 53. When the material cover 52 rotates relative to the material discharging guide 53, the material discharging port 51 can be closed, and when the material cover 52 is fixed relative to the material discharging guide 53, the material discharging port 51 can be opened. The powder box 20 is provided with a rib plate 21 protruding toward the material discharging component 50, and the material discharging guide 53 is provided with a block 532 protruding in the radial direction. The rib plate 21 is provided with a slot 212 extending in the vertical direction, and the block 532 is inserted into the slot 212, and a movable space for the block 532 is left in the slot 212 in the vertical direction. The discharge guide 53 is arranged to be connected with the powder box 20 with a reserved movable space, so that the discharge guide 53 can vibrate with the rotation of the feed shaft 61, thereby avoiding the phenomenon of powder sticking to the discharge guide 53. In particular, two blocks 532 can be provided, and the two blocks 532 are arranged opposite to each other along the radial direction of the discharge guide 53. Correspondingly, two slots 212 are also provided, and the two slots 212 are matched with the two blocks 532. The two slots 212 are arranged at intervals along the radial direction of the discharge guide 53, and the two slots 212 are staggered in the vertical direction, that is, the heights of the two slots 211 are different. Among them, the setting height of each slot 212 in the vertical direction and the relative horizontal positions of the two slots 212 enable the two blocks 532 to contact the slot wall of the corresponding slot 212 respectively at the powder discharge position or the powder discharge restriction position, and also facilitate the assembly of the discharge guide 53 on the powder box 20. The contact between the block 532 and the groove walls of the grooves 212 on both sides can enhance the vibration effect and further prevent the discharge guide 53 from being stained with powder.

[0055] The powder box 20 is provided with a collar 26 for supporting the discharge component 50, and a positioning block 266 is provided at the outer edge of the collar 26, and the positioning block 266 is connected to the powder box 20; a limit block 536 is provided at the outer edge of the discharge guide 53, and along the circumference of the feed shaft 61, the limit block 536 abuts against the positioning block 266 to limit the rotation range of the discharge guide 53. When the material cover 52 closes the discharge port 51, the limit block 536 and the positioning block 266 can prevent the discharge guide 53 from exiting the card slot 212.

[0056] Further, the powder box 20 is provided with a through hole 25 for the feeding shaft 61 to pass through, and a collar 26 is provided between the feeding shaft 61 and the through hole 25. The collar 26 is fixedly connected to the powder box 20, for example, by a buckle. The discharge component 50 is sleeved on the collar 26, and specifically, the second cylindrical portion 522 is sleeved on the collar 26. The provision of the collar 26 can strengthen the seal between the powder box 20 and the discharge component 50 to prevent powder leakage. In this embodiment, when it is necessary to discharge the powder, the driving mechanism 30 drives the feeding shaft 61 to rotate along the first direction. Since the material cover 52 is limited by the discharge guide 53, the feeding shaft 61 overcomes the interference force between the actuating member 35 and the inner wall of the hollow groove 361, and overcomes the friction between the actuating member 35 and the material cover 52. The feeding shaft 61 rotates alone to discharge the powder, and the material cover 52 is fixed relative to the discharge guide 53 to keep the discharge port 51 open. After the powder is discharged, the driving mechanism 30 drives the feeding shaft 61 to rotate in the second direction. The feeding shaft 61 drives the material cover 52 to rotate based on the interference force between the actuating member 35 and the inner wall of the hollow groove 361. The material cover 52 rotates relative to the discharge guide member 53 within the limited range of the limit groove 535 to Figure 6 The discharge port 51 is thereby closed.

[0057] Reference Figures 7 to 11 In another embodiment, the powder dispensing device 200 includes a powder box 20, and a discharge component 50a and a driving mechanism 30 respectively connected to both sides of the powder box 20. The discharge component 50a is arranged on one side of the powder box 20, and the discharge component 50a has a discharge port 51a connected to the powder box 20. The driving mechanism 30 is arranged on the other side of the powder box 20, and a feeding mechanism 60 is arranged in the powder box 20. The feeding mechanism 60 is at least partially arranged in the powder box 20. The driving mechanism 30 is used to drive the feeding mechanism 60 to transfer the powder in the powder box 20 to the discharge port 51a, and the powder falls into the target receiving port through the discharge port 51a. The target receiving port can be a mixing container for mixing powders, or a channel port for guiding powders to fall into the mixing container.

[0058] Among them, the discharge component 50a includes a material cover 52a, and the feeding mechanism 60 includes a feeding shaft 61. One end of the feeding shaft 61 is provided with an actuating member 35 protruding radially, and the actuating member 35 radially abuts against the material cover 52a. The discharge component 50a has a powder discharging allowing position and a powder discharging limiting position. In the powder discharging allowing position, the driving mechanism 30 controls the feeding shaft 61 to rotate in a first direction, the material cover 52a is limited, and the actuating member 35 rotates relative to the material cover 52a to keep the discharge port 51a in an open state; the driving mechanism 30 controls the feeding shaft 61 to rotate in a second direction opposite to the first direction by a preset angle, and the actuating member 35 drives the material cover 52a to rotate until the discharge port 51a is in a closed state, so that the discharge component 50a is in the powder discharging limiting position.

[0059] In this embodiment, the discharge port 51a can be controlled to rotate relative to the target receiving port to correspond to or stagger the position of the target receiving port. When powder output is required, the drive mechanism 30 can be controlled to drive the feed shaft 61 to rotate in the first direction, such as the motor rotates forward, the discharge port 51a corresponds to the target receiving port, and the discharge port 51a can discharge normally; when powder output is not required, the drive mechanism 30 can be controlled to drive the feed shaft 61 to rotate in the second direction, such as the motor rotates reversely, the discharge port 51a staggers with the target receiving port, and the discharge port 51a can stop discharging.

[0060] Furthermore, a matching ring 36 is provided between the material cover 52a and the feeding shaft 61, and the matching ring 36 is provided with a hollow groove 361, and the actuating member 35 passes through the hollow groove 361 and abuts against the material cover 52a. The matching ring 36 and the hollow groove 361 are provided, and the actuating member 35 interferes with the inner wall of the hollow groove 361 so that the actuating member 35 drives the material cover 52 to rotate, thereby ensuring the reliability of the actuating member 35 and the material cover 52 rotating together.

[0061] The actuator 35 is constructed as a steel column or a steel ball with a spherical surface. The feed shaft 61 is provided with an opening 611, and the actuator 35 is accommodated in the opening 611. In addition, the material cover 52a is sleeved on the end of the feed shaft 61, and a sealing ring 62 is provided between the material cover 52a and the feed shaft 61. Along the axial direction of the feed shaft 61, the sealing ring 62 is located on the side of the actuator 35 away from the material cover 52a. The structure and material of the actuator 35 and the matching ring 36 are the same as those in the first embodiment, and will not be repeated.

[0062] Reference Fig. 9 The discharge component 50a further includes a first cylindrical support portion 501, a material cover 52a is fixedly connected to the first cylindrical support portion 501, a discharge port 51a is arranged on the material cover 52a, and the first cylindrical support portion 501 is sleeved on the end of the feeding shaft 61. In the powder discharging position, the discharge port 51a is maintained at a position corresponding to the target receiving port; in the powder discharging position, the discharge port 51a rotates with the material cover 52a to a position staggered from the target receiving port. The rotation of the material cover 52a itself drives the position of the discharge port 51a to change, thereby simplifying the structure of the discharge component 50a and making the whole more compact.

[0063] The powder box 20 is provided with a limiting rib 23 protruding toward the material discharging component 50a. At the powder discharging allowing position, the material cover 52a is limited by the target receiving port; at the powder discharging limiting position, the material cover 52a is limited by the limiting rib 23. The target receiving port and the powder box 20 are both fixed components, and the limiting of the material cover 52a is more reliable.

[0064] Furthermore, the discharge component 50a further includes a second cylindrical support portion 502, the powder box 20 is provided with a through hole 25 for the feeding shaft 61 to pass through, a clamping ring 26 is provided between the feeding shaft 61 and the through hole 25, the clamping ring 26 is fixedly connected to the powder box 20, and the discharge component 50a is sleeved on the clamping ring 26, specifically, the second cylindrical support portion 502 is sleeved on the clamping ring 26. The provision of the clamping ring 26 can strengthen the seal between the powder box 20 and the discharge component 50a to prevent powder leakage.

[0065] In this embodiment, the target receiving port is formed by a frame structure, and the frame limits the rotation of the material cover 52a to form the target receiving port. When the powder needs to be discharged, the driving mechanism 30 drives the feed shaft 61 to rotate in the first direction. Since the material cover 52a is limited by the target receiving port, the feed shaft 61 overcomes the interference force between the actuator 35 and the inner wall of the hollow groove 361, and overcomes the friction force between the actuator 35 and the material cover 52a. The feed shaft 61 rotates alone to discharge the powder, and the material cover 52a remains at a position corresponding to the discharge port 51a and the target receiving port. After the powder is discharged, the driving mechanism 30 drives the feed shaft 61 to rotate in the second direction. Based on the interference force between the actuator 35 and the inner wall of the hollow groove 361, the feed shaft 61 drives the material cover 52a to rotate to the position as shown in the figure. Fig.11 In the position shown, the material cover 52a rotates relative to the target receiving opening and is limited by the limiting ribs 23 of the powder box 20, so that the discharge opening 51a is offset from the target receiving opening.

[0066] In the present invention, by controlling the discharge ports 51, 51a to correspond to or stagger with the target receiving port along the gravity direction, the discharge ports 51, 51a can be automatically opened or closed, reducing the waste of powder, and preventing the steam in the mixing container from entering the material cover 52, 52a and the powder box 20 from the discharge ports 51, 51a, thereby playing a moisture-proof role, which can not only prevent a small amount of powder from being damp and adhering to the discharge parts 50, 50a, reduce the cleaning frequency and cost, ensure the powder discharge efficiency, but also avoid affecting the quality of the powder in the powder box 20, and ensure the taste of the drink. In addition, the material cover 52, 52a is driven by the radially protruding actuator 35, and the discharge ports 51, 51a are reliably opened and closed through a simple structure.
