[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0053] Embodiment one

[0054] Referring to Figures 1-7 The utility model provides a kind of sealing mechanism for blade type lower powder, including the machine body 2 being equipped with storage cavity 21 and the powder box assembly 1 being placed in storage cavity 21 separately, the powder box assembly 1 includes powder storage box 11 and powder outlet dial 12, the powder storage box 11 is equipped with the powder storage cavity 111 for storing powder, the bottom of the powder storage box 11 is equipped with the powder outlet 112 being communicated with powder storage cavity 111;The powder outlet dial 12 is rotationally arranged in powder storage cavity 111;The powder outlet dial 12 includes blade 121, when driving powder outlet dial 12 rotation, can drive blade 121 rotation to be with the powder in powder storage cavity 111 dial to powder outlet 112 to realize powder falling.

[0055] In addition, the powder box assembly 1 further includes sealing element 13 movably arranged at the bottom of powder storage box 11 and used for opening or closing powder outlet 112, and first transmission member 17 penetratingly arranged on powder storage box 11 and used for driving powder outlet dial 12 to rotate;The first driving device 25 and the second driving device 26 are further arranged in the machine body 2, the output end of the first driving device 25 is drivingly connected with the second transmission member 22, the second transmission member 22 is at least partially located in storage cavity 21 and is used for drivingly cooperating with the first transmission member 17 to drive powder outlet dial 12 to rotate;The output end of the second driving device 26 is drivingly connected with the third transmission member, and the third transmission member is at least partially located in storage cavity 21 and is used for driving sealing element 13 to act;In addition, the controller is further arranged in the machine body 2, and the first driving device 25 and the second driving device 26 are controlled to act by electrically connecting.

[0056] Therefore, by adopting the lower plane type sealing, not only the opening angle of powder outlet 112 can be set to 180 degrees, so that the powder falling is more smooth, and the powder blocking phenomenon is not easy to occur, and the sealing performance is better, so that the risk of powder leakage can be greatly reduced.

[0057] The sealing mechanism for the blade type powder outlet provided by the utility model, by setting the first driving device 25 and the second driving device 26 on the machine body 2 to drive the powder outlet paddle 12 and the sealing piece 13 to rotate respectively, the transmission cooperation relationship is simpler, the cooperation precision requirement is lower, and the control logic is also simpler; in addition, since two driving devices are separated to drive the powder outlet paddle 12 and the sealing piece 13 respectively, it is not necessary to set a transmission assembly at the bottom of the sealing piece 13, only a third transmission piece for driving the sealing piece 13 to act is set on the second driving device 26, thereby simplifying the overall structure of the powder box assembly 1, and the disassembly, washing and maintenance are more convenient.

[0058] The machine body 2 further comprises a shell plate 27, and the first driving device 25, the second driving device 26, the second transmission piece 22 and the third transmission piece are all arranged on the shell plate 27.

[0059] In the embodiment of the utility model, the first driving device 25 and the second driving device 26 are both driving motors and are electrically connected with the controller.

[0060] In the embodiment of the utility model, a top cover 16 is further included, which is arranged on the top of the powder storage box 11 to seal the powder storage cavity 111.

[0061] Furthermore, the controller controls the first driving device 25 and the second driving device 26 to act in sequence to make the sealing piece 13 and the powder outlet paddle 12 act differentially. Specifically, when powder needs to be discharged, the sealing piece 13 acts first to open the powder falling port 112, and then the powder outlet paddle 12 rotates to realize powder discharge; when sealing is needed, the powder outlet paddle 12 acts first to pause rotation to stop powder discharge, and then the sealing piece 13 acts to close the powder falling port 112.

[0062] In this way, since the powder discharge and the sealing are staggered in time, when milk is prepared, the sealing piece 13 acts first to open the powder falling port 112, and when sealing is performed, the sealing piece 13 lags behind the powder outlet paddle 12 to seal the powder falling port 112, so that the flying powder generated in the process of opening or sealing the powder falling port 112 can be reduced, and the structure is simpler and more reliable.

[0063] It should be noted that in other embodiments, the sealing piece 13 can also act simultaneously with the powder outlet paddle 12, which is not limited here.

[0064] Reference Figures 3-5The sealing member 13 is a first sealing cover plate rotatably arranged at the bottom of the powder storage box 11 and coaxially arranged with the first transmission member 17. Specifically, the first sealing cover plate comprises a first cover plate body 131 and a first convex plate portion 132 extending from the edge of the first cover plate body 131. When the first sealing cover plate is rotated, the first convex plate portion 132 can be rotated to cover or expose the powder falling port 112, thereby realizing the closing or opening of the powder falling port 112.

[0065] The bottom surface of the powder storage box 11 is formed with a first sealing surface matched with the top surface of the first convex plate portion 132, and the powder falling port 112 is located on the first sealing surface. In this embodiment, the first sealing surface is the bottom surface of the powder storage box 11, which is a flat surface, and the top surface of the first convex plate portion 132 is also a flat surface. In this way, when the first convex plate portion 132 is rotated to the powder falling port 112, the powder falling port 112 can be completely sealed, thereby ensuring the sealing effect.

[0066] Of course, in other embodiments, the first sealing surface can also be other shaped surfaces, such as arc surfaces, conical surfaces, etc., as long as the top surface of the first convex plate portion 132 is matched with the shape, which is not limited here.

[0067] The third transmission member is a first transmission disc 23 partially located in the storage cavity and in transmission connection with the first sealing cover plate. The first transmission disc 23 is provided with a first clamping block 231, and the first sealing cover plate is provided with a first clamping hole 1311 in clamping connection with the first clamping block 231 to realize the transmission connection. In addition, the output shaft of the second driving device 26 is sleeved with a first gear 24, and the first transmission disc 23 is provided with a second gear 232 in meshing transmission with the first gear 24.

[0068] Therefore, when the second driving device 26 drives the first gear 24 to rotate, the first transmission disc 23 can be driven to rotate through the meshing transmission of the first gear 24 and the second gear 232, and then the first sealing cover plate can be driven to rotate through the clamping connection of the first clamping block 231 and the first clamping hole 1311, thereby realizing the opening or closing of the powder falling port 112.

[0069] It should be noted that in other embodiments, the sealing member can also be a second sealing cover plate rotatably arranged at the bottom of the powder storage box 11 and non-coaxially arranged with the first transmission member 17. Specifically, the second sealing cover plate comprises a second cover plate body and a second convex plate portion extending from the edge of the second cover plate body, and when the second sealing cover plate is driven to rotate, the second convex plate portion can cover or expose the powder falling port 112 to achieve the closing or opening of the powder falling port 112. Wherein, the bottom surface of the powder storage box 11 is formed with a second sealing surface matched with the top surface of the second convex plate portion, and the powder falling port 112 is located on the second sealing surface; and the third transmission member is a second transmission disc partially located in the storage cavity 21 and transmissionally connected with the second sealing cover plate and the output end of the second driving device 26.

[0070] Therefore, when the second driving device 26 drives the second transmission disc to rotate, the second transmission disc can drive the second sealing cover plate to rotate to achieve the opening or closing of the powder falling port 112. Therefore, when the second sealing cover plate is used as the sealing member 13, the first gear 24 and the second gear 232 can be omitted, so that the structure is simpler, and the same sealing effect can be achieved.

[0071] Further referring to Figures 3-5 The bottom of the powder storage cavity 111 is annularly provided with a powder guiding groove 113, and the powder falling port 112 and the powder guiding groove 113 are in communication and form a three-dimensional opening. The three-dimensional opening is different from the existing planar powder outlet, and can avoid the powder from caking at the powder falling port 112, thereby realizing continuous powder falling. In addition, the bottom of the blade 121 abuts against the powder guiding groove 113, and the blade 121 is matched with the powder guiding groove 113, so that when the powder outlet dial 12 is driven to rotate, the blade 121 can be driven to move along the powder guiding groove 113. Specifically, the lower end surface of the blade 121 is protruded downward, and the lower end surface of the blade 121 is matched with the upper end surface of the powder guiding groove 113, thereby facilitating the blade 121 to push the powder out.

[0072] In the embodiment of the utility model, the recess 114 in communication with the powder falling port 112 is further formed in the bottom of the powder storage box 11, and the groove diameter of the recess 114 is greater than the diameter of the powder falling port 112. Therefore, by arranging the recess 114, the powder can be prevented from adhering to the outside of the powder falling port 112, thereby making the powder fall more smoothly.

[0073] Further, the powder outlet dial 12 further comprises a disc body 123, and the blade 121 is provided with a plurality of blades and is annularly and spacedly arranged along the circumferential side of the disc body 123. Adjacent blades 121 form a powder storage compartment 122 for storing powder. Wherein, the powder storage compartment 122 is a through slot, and when the powder outlet dial 12 is driven to rotate and the powder storage compartment 122 is aligned and communicated with the powder falling port 112, the powder in the powder storage compartment 122 can fall out from the powder falling port 112 to realize powder falling.

[0074] In the embodiment, the disc body 123 is connected with the plurality of blades 121 and integrally formed.

[0075] In addition, a material blocking plate 14 is arranged in the powder storage cavity 111 and above the powder discharging disc 12, and a powder falling cavity is formed between the material blocking plate 14 and the bottom of the powder storage cavity 111, and the powder discharging disc 12 is rotatably arranged in the powder falling cavity; wherein the material blocking plate 14 is provided with a powder inlet 141 communicating with the powder falling cavity; in addition, a material guiding wheel 15 is arranged above the material blocking plate 14, the material guiding wheel 15 is movably arranged relative to the material blocking plate 14 and is used for pushing the powder to the powder inlet 141, and the material guiding wheel 15 is provided with two push rods 151 arranged at intervals.

[0076] The powder discharging disc 12 and the material guiding wheel 15 are rotatably arranged relative to the material blocking plate 14, and the powder discharging disc 12 and the material guiding wheel 15 are in driving connection with the first driving member 17; specifically, the first driving member 17 includes a first driving shaft 171 penetrating the powder storage box 11, and a connecting sleeve 18 is arranged on the upper portion of the first driving shaft 171, and the connecting sleeve 18 is in clamping connection with the powder discharging disc 12 and the material guiding wheel 15 to realize driving cooperation.

[0077] Therefore, when the first driving shaft 171 is driven to rotate, the connecting sleeve 18 is driven to rotate, and then the powder discharging disc 12 and the material guiding wheel 15 are driven to rotate to realize powder discharging.

[0078] In addition, the lower end of the first driving shaft 171 is provided with a third driving disc 172 in driving cooperation with a second driving member 22. Specifically, the second driving member 22 includes a second driving shaft 221, and the upper end of the second driving shaft 221 is provided with a fourth driving disc 222 located in the powder storage cavity 21, the third driving disc 172 is provided with a plurality of clamping grooves 1721, and the fourth driving disc 222 is provided with a plurality of clamping claws 223 in clamping cooperation with the plurality of clamping grooves 1721 to realize driving connection; the lower end of the second driving shaft 221 is in driving connection with the output shaft of the first driving device 25 through a shaft sleeve.

[0079] Therefore, when the first driving device 25 drives the second driving shaft 221 to rotate, the fourth driving disc 222 is driven to rotate, and the third driving disc 172 is driven to rotate through the clamping cooperation of the plurality of clamping claws 223 and the plurality of clamping grooves 1721, and then the first driving shaft 171 is driven to rotate.

[0080] Embodiment two

[0081] Reference Figures 8-11The difference between the lower powder sealing mechanism and the first embodiment lies in the structure of the sealing member 13. In the embodiment, the sealing member 13 is a third sealing cover plate 19 slidingly arranged at the bottom of the powder storage box 11, and the third sealing cover plate 19 can cover or expose the powder falling opening 112 to open or close the powder falling opening 112.

[0082] Specifically, the bottom of the powder storage box 11 is provided with a sliding groove for the third sealing cover plate 19 to slide, the bottom surface of the sliding groove forms a third sealing surface matched with the top surface of the third sealing cover plate 19, and the powder falling opening 112 is located on the third sealing surface. In the embodiment, the third sealing surface is a plane, and the top surface of the third sealing cover plate 19 is also a plane. The third transmission member is a transmission plate 28, the top of the transmission plate 28 is provided with a second clamping block 281, the bottom of the third sealing cover plate 19 is provided with a second clamping hole 191, and the second clamping block 281 is clamped into the second clamping hole 191 to realize transmission connection. The second driving device 26 is transmissionally connected with a third gear 29 at the output end, and the transmission plate 28 is provided with a rack transmissionally engaged with the third gear 29.

[0083] Therefore, when the second driving device 26 drives the third gear 29 to rotate, the transmission plate 28 can be driven to slide through the meshing transmission of the rack, and then the third sealing cover plate 19 is driven to slide to open or close the powder falling opening.

[0084] In the embodiment of the utility model, the shell plate 27 is provided with a sliding groove 271 for the transmission plate 28 to slide.
