Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, in particular to a milk powder machine with high sealing and moisture-proof performance. Background Art

[0002] Currently, infant formula is typically packaged in cans or bags. Before preparing formula, the following steps are required: opening the package, removing the scoop, manually scooping the powder several times, placing the scoop back down, and sealing the package. In practice, this repeated manual scooping can lead to inaccurate amounts of powder being dispensed, and powder can easily spill during the scoop's movement. Furthermore, the multiple and time-consuming steps involved in removing powder can expose the opened package to air, making it susceptible to moisture and contamination.

[0003] In the prior art, some electric milk powder dispensers have gradually emerged. These dispensers pre-load milk powder into a hopper and automatically dispense a fixed amount of powder on demand. The inventors, through long-term user experience research, discovered that while these dispensers are convenient, they suffer from structural design flaws. The hopper's seal is poor, making the remaining powder susceptible to moisture. Utility Model Content

[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0024] See also Figures 1 to 6As shown, the utility model provides a milk powder machine with high sealing and moisture-proof performance, including a shell 1, a milk powder bin 2, a milk powder stirring mechanism 3, a milk powder extruding mechanism 4 and a movable sealing mechanism 5, wherein the milk powder bin 2 is detachably mounted on the top of the shell 1, and a sealing top cover 6 is detachably mounted on the top of the milk powder bin 2. The milk powder bin 2 is also provided with a powder discharge channel 7 connected to the inner space of the milk powder bin 2; the milk powder stirring mechanism 3 includes a stirring motor 301 and a stirring blade 302 driven by the stirring motor 301 and extending into the milk powder bin 2, and the part of the milk powder stirring mechanism 3 passing through the milk powder bin 2 is sealed by a first sealing member 8; the milk powder extruding mechanism 4 includes an extrusion motor 401 and an extrusion screw 402 driven by the extrusion motor 401 and extending into the powder discharge channel 7, and the part of the milk powder extruding mechanism 4 passing through the powder discharge channel 7 is sealed by a second sealing member 9; the movable sealing mechanism 5 is mounted on the shell 1 and close to the powder discharge port 701 of the powder discharge channel 7, for controlled sealing or exposing the powder discharge port 701.

[0025] In this embodiment, the top opening, powder outlet, bottom stirring mechanism loading port, and extrusion mechanism loading port of the milk powder silo 2, which are the air inlet channels, are sealed with a sealing top cover 6, a movable sealing mechanism 5, a first sealing member 8, and a second sealing member 9, respectively. This greatly enhances the all-around sealing performance of the milk powder silo, preventing the milk powder stored in the milk powder silo 2 from coming into contact with the outside air, thereby preventing the milk powder in the milk powder machine from becoming damp or contaminated. Preferably, the first sealing member 8 and the second sealing member 9 are both oil seals.

[0026] According to one example of the present invention, the interior of the milk powder bin 2 is divided by a partition 10 into an upper milk powder storage area X1 and a lower device assembly area X2. A sealed bottom cover 11 is installed at the bottom end of the milk powder bin 2 to seal the lower device assembly area X2. The extrusion motor 401 of the milk powder extrusion mechanism 4 is installed within the lower device assembly area X2. In this application, the relevant components of the milk powder extrusion mechanism 4 are directly integrated into the milk powder bin 2. An external power supply can be connected via contact points, which takes into account the quick disassembly and cleaning convenience of the milk powder bin 2 and the sealing performance.

[0027] According to one example of the present invention, the central portion of the sealed bottom cover 11 is provided with an annular protrusion 1101 extending toward the partition 10. The gap between the annular protrusion 1101 and the partition 10 is sealed by at least one first sealing ring 12. A passage for the stirring shaft 303 of the stirring motor 301 is provided on the inner side of the annular protrusion 1101 and in the central portion of the partition 10. The stirring shaft 303 passes through the sealed bottom cover 11, the lower component assembly area X2, and the partition 10, and is removably connected to the stirring blade 302 disposed in the upper milk powder storage area X1. The gap between the stirring shaft 303 and the partition 10 is sealed by a first sealing member 8. This design allows the milk powder silo 2 to be disassembled without the stirring mechanism, while maintaining the sealing performance of the stirring shaft during normal use.

[0028] According to an example of the present invention, the powder outlet channel 7 is arranged at the edge of the partition 10, and the extrusion shaft 403 of the extrusion motor 401 passes through the plate body of the powder outlet channel 7 of the partition 10 and is connected to the extrusion screw 402 arranged in the powder outlet channel 7. The gap between the extrusion shaft 403 and the partition plate body at the powder outlet channel 7 is closed by the second seal 9 to improve the sealing performance of the extrusion mechanism at the installation position.

[0029] According to an example of the present invention, after partition design is performed by the partition 10 , the gap between the peripheral edge of the sealed bottom cover 11 and the lower edge of the silo body of the milk powder silo 2 is closed by at least one second sealing ring 13 .

[0030] According to one embodiment of the present invention, the stirring blade 302 is detachably fixed to the middle of the partition 10 by magnetic attraction. This design allows the stirring blade 302 to be magnetically fixed to the partition 10 even after being detached from the stirring shaft 303 of the stirring motor 301. This prevents the parts from shifting and scattering, and makes it easier to re-install them on the stirring shaft 303 after cleaning.

[0031] As one implementation, the movable sealing mechanism 5 includes a sealing platform 501 and a sealing motor 502 disposed on the housing 1 for driving the sealing platform 501 toward or away from the powder outlet 701. Furthermore, the movable sealing mechanism 5 also includes a movable block 503 linearly slidably mounted on the housing 1. The sealing platform 501 is disposed at the end of the movable block 503. The movable block 503 is provided with a rack 504. A gear 505 meshing with the rack 504 is mounted on the output shaft of the sealing motor 502.

[0032] The sealing motor 502 drives the sealing platform 501 to move back and forth via a rack and pinion transmission, causing the inner sidewall of the sealing platform 501 to approach and cling to the powder outlet 701, completing the seal. In other feasible designs, the movable sealing mechanism 5 can also be a motor-driven flap structure, which opens or closes the powder outlet 701 by rotating the flap.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features.
