[0002] For a long time, when people prepare infant formula, they often worry about how many spoons of formula to put, how many milliliters of water to add, and what the ratio of water to milk is. For this reason, automatic milk preparation machines have appeared on the market, which mainly control the automatic output of formula and water through a controller, thereby controlling the ratio of water to milk and the final output of milk.

[0003] In order to achieve accurate powder discharge, the prior art usually adopts a turntable with multiple storage slots spaced apart in the powder storage box, and the turntable is driven to rotate by a driving mechanism so that the multiple storage slots are sequentially opposite to the discharge holes at the bottom of the powder storage box, and the milk powder in the discharge slots falls from the discharge holes. Since each storage slot can only accommodate 1-2 grams of milk powder, the powder discharge amount can be controlled more accurately. For example, Chinese utility model patents CN205433363U and CN211242897U both adopt the above structure for discharge.

[0004] However, since the material storage grooves of the above structure are arranged at intervals, the powder discharge method of the above structure is intermittent, which will lead to uneven powder discharge and the milk powder cannot be fully dissolved in water; and after the powder discharge of the above structure is completed, if the material storage groove is opposite to the discharge hole, external water vapor can enter the interior of the powder storage box through the discharge hole and the material storage groove, thereby causing the milk powder to become damp and clump, affecting the powder discharge accuracy and affecting the quality of the milk powder.

DETAILED DESCRIPTION

[0037] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0038] Example 1

[0039] like Figures 1 to 14 As shown, the utility model provides a powder discharging mechanism, which specifically adopts the following technical solutions:

[0040] A powder discharging mechanism comprises a powder storage box 1 and a driving shaft 2, wherein a mounting through hole 11 is provided in the middle of the bottom of the powder storage box 1, the driving shaft 2 passes through the mounting through hole 11 from bottom to top and extends into the interior of the powder storage box 1, a discharge port 12 is provided at the bottom of the powder storage box 1 on one side of the mounting through hole 11, and a powder discharging disc 3, a powder scraping rotating disc 4 and a stirring rotating disc 6 are sequentially arranged inside the powder storage box 1 from bottom to top; the powder discharging disc 3 is movably sleeved on the outer side wall of the mounting through hole 11, and the powder scraping rotating disc 4 and the stirring rotating disc 6 are arranged in sequence from bottom to top; the powder discharging disc 3 is movably sleeved on the outer side wall of the mounting through hole 11, and the powder scraping rotating disc 6 is 4 and the stirring turntable 6 are both sleeved on the driving shaft 2 and are both transmission connected to the driving shaft 2; a powder storage channel 34 is formed between the powder discharge disc 3 and the powder scraping turntable 4, and a plurality of scrapers 41 extending into the powder storage channel 34 are arranged at the bottom of the powder scraping turntable 4, and a discharge groove 31 is arranged at the bottom of the powder discharge disc 3 corresponding to the position of the powder storage channel 34, and the powder discharge disc 3 can rotate under the action of external force, thereby changing the relative position between the discharge groove 31 and the discharge port 12.

[0041] Specifically, the powder discharge tray 3 can rotate under the action of external force, so that the powder discharge tray 3 is switched between the powder discharge position and the closed position. When the powder discharge tray is in the powder discharge position, the discharge slot 31 and the discharge port 12 are aligned up and down and the two are connected. At this time, the milk powder can fall from the discharge slot 31 to the discharge port 12, thereby realizing powder discharge; when the powder discharge tray is in the closed position, the discharge slot 31 and the discharge port 12 are staggered and the two are not connected, that is, the discharge slot 31 and the discharge port 12 are both in a closed state, and powder cannot be discharged at this time; such an arrangement makes it possible to close the discharge slot 31 and the discharge port 12 in time after the powder discharge is completed to prevent the milk powder from falling, and to prevent external water vapor from entering the interior of the powder storage box 1 through the discharge slot 31 and the discharge port 12 to cause the milk powder to become damp and agglomerated, thereby ensuring the quality of the milk powder.

[0042] During actual use, the bottom of the driving shaft 2 is connected to an external driving component, such as a driving motor. Milk powder is stored in the powder storage box 1. When powder is to be discharged, the driving motor drives the driving shaft 2 to rotate forward, and the driving shaft 2 then drives the powder scraping turntable 4 and the stirring turntable 6 to rotate forward. The stirring turntable 6 breaks up and pushes the milk powder during the rotation to prevent the milk powder from sticking together, making it easier for the milk powder to fall into the powder storage channel 34 under the action of its own gravity. During the rotation, the powder scraping turntable 4 drives the scraper 41 at the bottom to push the milk powder in the powder storage channel 34 to move forward. Because the powder discharge plate 3 is in the closed position when it is just started, the moving milk powder will generate a positive driving force on the powder discharge plate 3. Under the action of the positive driving force of the milk powder, the powder discharge plate 3 rotates forward and rotates to discharge the powder. The powder discharging plate 31 is moved to the bottom of the powder discharging plate 31 and the powder discharging plate 32 is moved to the bottom of the powder discharging plate 31 and the powder discharging plate 32 is moved to the bottom of the powder discharging plate 31 and the powder discharging plate 32 is moved to the bottom of the powder discharging plate 31 and the powder discharging plate 32 is moved to the bottom of the powder discharging plate 31 and the powder discharging plate 32.

[0043] Furthermore, a powder guide disk 5 is provided between the powder scraping turntable 4 and the stirring turntable 6, and a plurality of powder guide through holes 51 are provided on the powder guide disk 5, and a powder guide plate 52 is provided between the powder guide through holes 51; there is no relative rotational movement between the powder guide disk 5 and the powder storage box 1. Specifically, a fixing block 53 is provided on the edge of the powder guide disk 5 protruding outward, and a receiving groove 15 is correspondingly provided on the inner wall of the powder storage box 1. When the powder guide disk 5 is installed, the through hole in the middle of the powder guide disk is sleeved on the outer wall of the through hole in the middle of the powder scraping turntable 4 and the fixing block 53 is clamped in the receiving groove 15. When the driving shaft 2 rotates, since the fixing block 53 is clamped in the receiving groove 15, the powder guide disk 5 does not rotate with the driving shaft 2.

[0044] In actual use, the milk powder inside the powder storage box 1 falls into the powder storage channel 34 through the powder guiding holes 51, and the powder guiding plates 52 between the powder guiding holes 51 cover part of the powder storage channel 34; when the powder is to be discharged, the powder scraping turntable 4 drives the scraper 41 at the bottom to push the milk powder in the powder storage channel 34 to move forward during the rotation. When the milk powder passes through the powder guiding plates 52, the powder guiding plates 52 can squeeze the milk powder in the powder storage channel 34 to prevent the milk powder from overflowing from the powder storage channel 34 during the movement, thereby forming a hollow space between the milk powder in the powder storage channel 34, thereby causing inaccurate powder discharge.

[0045] Further, the upper surface of the powder discharge plate 3 is provided with a groove 32, and the lower surface of the powder scraping rotary plate 4 is provided with a protruding wall 42, the protruding wall 42 extends into the groove 32, and the powder storage channel 34 is formed between the protruding wall 42 and the groove 32. Preferably, the powder scraping rotary plate 4 is evenly provided with a plurality of protruding plates 43 on the outer side of the protruding wall 42, and each of the protruding plates 43 is equipped with a scraper 41.

[0046] In this embodiment, the powder storage channel 34 is formed by the outer wall of the protruding wall 42 and the inner wall of the groove 32. By setting a plurality of protruding plates 43, the scraper 41 can be installed and a gap can be provided between the protruding plates 43 for the milk powder to fall into the powder storage channel 34. Exemplarily, the number of the protruding plates 43 and the scraper 41 is set to N (for example, 4), and they are evenly distributed along the powder scraping turntable 4. When the N scrapers extend into the powder storage channel 34, the N scrapers divide the continuous powder storage channel 34 into N chambers, and the volume in each chamber is the same, so that the amount of milk powder in each chamber is the same; when the powder scraping turntable 4 drives the scraper 41 at the bottom to move forward during the rotation process, each scraper 41 pushes the milk powder in the corresponding chamber to move forward until the milk powder falls from the discharge slot 31. When the driving shaft 2 drives the powder scraping turntable 4 to rotate 1 / N circle, the milk powder in one chamber is just driven to fall from the discharge slot 31. In actual use, the specific weight of the milk powder in each chamber can be accurately calculated according to the number of scrapers 41. Since the weight of the milk powder in each chamber is the same, the powder output is the same when the driving shaft 2 rotates 1 / N times; therefore, the specific number of rotations of the driving shaft 2 can be controlled according to the specific powder output requirements, thereby accurately controlling the powder output. Moreover, the powder storage channel 34 is continuous, and on the basis of accurately controlling the powder output, uninterrupted powder output can also be achieved. Compared with the powder storage tanks arranged at intervals in the prior art, the uniformity of powder output can be ensured, so that the milk powder can be evenly and fully contacted with water, ensuring that the milk powder is fully dissolved in water.

[0047] Furthermore, a limiting block 33 is provided protruding outwardly from the edge of the powder output tray 3, and a limiting groove 13 is provided on the inner wall of the powder storage box 1, and the limiting block 33 is located in the limiting groove 13. Specifically, as Figure 3-5As shown, when powder is to be discharged, the scraper 41 pushes the milk powder in the powder storage channel 34 to move forward. Under the positive driving force of the milk powder, the powder discharge tray 3 rotates forward. At this time, the limit block 33 rotates forward from one end (for example, the left end) of the limit groove 13 to the other end (for example, the right end) of the limit groove 13. When the limit block 33 rotates to the other end of the limit groove 13, the powder discharge tray 3 can no longer rotate due to the limiting effect of the limit groove 13 on the limit block 33. At this time, the powder discharge tray 3 stays at the powder discharge position to achieve powder discharge. When the powder discharge is finished, the scraper 41 pushes the storage channel 34 to move forward. The milk powder in the powder channel 34 moves in the opposite direction. Under the reverse driving force of the milk powder, the powder output tray 3 rotates in the opposite direction. At this time, the limit block 33 rotates in the limit groove 13 from the other end (for example, the right end) of the limit groove 13 to one end (for example, the left end) of the limit groove 13. When the limit block 33 rotates to one end of the limit groove 13, the powder output tray 3 can no longer continue to rotate due to the limiting effect of the limit groove 13 on the limit block 33. At this time, the powder output tray 3 stays in the closed position, and the discharge slot 31 and the discharge port 12 are closed in time to prevent the milk powder from continuing to fall and prevent the milk powder from getting damp and agglomerating. This embodiment is simple in structure by providing the limit groove 13 and the limit block 33 that cooperate with each other, and can well control the powder output tray 3 to switch between the powder output position and the closed position.

[0048] Furthermore, the discharge channel 31 has a first end and a second end, the first end is provided with a first inclined plate 35 inclined downward toward the second end, and the second end is provided with a second inclined plate 36 inclined upward toward the first end. In this embodiment, when the scraper 41 pushes the milk powder in the powder storage channel 34 to move forward to the discharge channel 31, the first inclined plate 35 inclined downward is provided to facilitate guiding the milk powder to move downward and fall from the discharge channel 31; the second inclined plate 36 inclined upward is provided to facilitate the moving milk powder to generate a positive or reverse driving force on the second inclined plate 36, thereby pushing the powder discharge tray 3 to switch between the powder discharge position and the closed position, without the need to provide an additional driving mechanism to drive the powder discharge tray 3, which is conducive to simplifying the structure.

[0049] Furthermore, the stirring turntable 6 includes a sleeve 61 and a fixed outer ring 62, the sleeve 61 is used to be sleeved on the driving shaft 2, and a plurality of support rods 63 are evenly arranged on the outside of the sleeve 61, and a plurality of first vertical rods 64 are arranged above each of the support rods 63, and a stirring rod 65 is extended outward on the same side of each of the support rods 63, and the outer end of each stirring rod 65 is connected to the fixed outer ring 62; preferably, the stirring rod 65 includes a first scraper rod 651, a second scraper rod 652 and a connecting rod 653, the first scraper rod 651 and the second scraper rod 652 are arranged at a certain angle, and the first scraper rod 651 and the second scraper rod 652 are connected by the connecting rod 653.

[0050] In this embodiment, a plurality of first vertical rods 64 are provided above each support rod 63. During the rotation of the stirring turntable 6, the first vertical rod 64 passes through the middle of the milk powder, thereby breaking up the milk powder located in the middle of the powder storage box 1, preventing the milk powder from clumping together to form a hollow milk powder, and making it easier for the milk powder to fall down due to gravity; and by providing the first scraper rod 651 and the second scraper rod 652, and the first scraper rod 651 and the second scraper rod 652 are provided at a certain angle, during the rotation of the stirring turntable 6, the first scraper rod 651 and the second scraper rod 652 can push the milk powder to move in different directions, not only breaking up the milk powder located at the bottom of the powder storage box 1, but also pushing the milk powder to move to the position of the powder guide through hole 51 of the powder guide disk 5, so as to facilitate pushing the milk powder from the powder guide through hole 51 to fall into the powder storage channel 34.

[0051] Furthermore, it also includes a powder box cover 7, which is detachably arranged on the top of the powder storage box 1, and a plurality of card blocks 71 are protruding outward on the side wall of the powder box cover 7, and a plurality of card slots 14 matching with the card blocks are arranged on the inner wall of the powder storage box 1, and a sealing ring 8 is also sleeved on the side wall of the powder box cover 7. Specifically, a grip 72 is also arranged on the top of the powder box cover 7, and a plurality of second vertical rods 73 are also arranged on the bottom of the powder box cover 7. In actual use, when it is necessary to add milk powder to the powder storage box 1, grasp the handle 72 and screw the powder box cover 7 to make the block 71 disengage from the locking position of the slot 14, and then pull out the powder box cover 7. After the milk powder is added, grasp the handle 72 again to cover the powder box cover 7 on the powder storage box 1, screw the powder box cover 7 to make the block 71 move to the locking position of the slot 14, so as to lock the powder box cover 7 and the powder storage box 1 and prevent the powder box cover 7 from detaching from the powder storage box 1; and by providing a sealing ring 8, the sealing between the powder box cover 7 and the powder storage box 1 is further ensured to prevent the milk powder in the powder storage box 1 from getting damp. In addition, a second vertical rod 73 is provided at the bottom of the powder box cover 7. When the amount of milk powder in the powder storage box 1 is large, the stirring turntable 6 rotates to push the milk powder through the second vertical rod 73. The second vertical rod 73 can assist in breaking up the milk powder on the upper part of the powder storage box 1, allowing the milk powder to fall down better due to gravity, preventing the milk powder from clumping together to form a hollow milk powder, and achieving more accurate powder discharge.
