DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the following embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0036] The utility model provides an automatic milk powder brewing machine, comprising a quantitative milk powder dispensing unit, a primary milk powder brewing unit and a secondary shaking unit that cooperate with each other in sequence. The quantitative milk powder dispensing unit is used to transport milk powder in a quantitative manner to the primary milk powder brewing unit for primary mixing and brewing, and then transport it to the secondary shaking unit for secondary shaking; wherein, the secondary shaking unit includes a vertically arranged arc guide rail 3 and a multi-axis movable platform 4 coordinated with the arc guide rail 3; the multi-axis movable platform 4 is used to shake and mix the milk, and can move up and down along the arc guide rail 3 to take out and put in a container containing the milk.

[0037] With this arrangement, after the milk powder is dispensed, it is initially brewed. The multi-axis mobile platform 4 then collects the initially brewed milk and shakes it a second time, eliminating clumping and unevenness, thereby brewing high-quality milk. Furthermore, the multi-axis mobile platform 4 can move up and down along the curved guide rail 3 to facilitate the placement and removal of milk containers, making it more convenient to use.

[0038] Specifically, the multi-axis mobile platform 4 includes a horizontal transverse guide rail 9, an arc-shaped ring 11, a magnetic disc 12, a sliding base 10, a first motor and a second motor; the horizontal transverse guide rail 9 cooperates with the arc-shaped guide rail 3, and the sliding base 10 is sleeved on the horizontal transverse guide rail 9 and is rotatably connected to the arc-shaped ring 11 through a first rotating shaft 13; the magnetic disc 12 is rotatably connected to the arc-shaped ring 11 through a second rotating shaft 14, and is used to fix the container containing the milk; the first motor is used to drive the rotation of the first rotating shaft 13, and the second motor is used to drive the rotation of the second rotating shaft 14 to shake and mix the container containing the milk.

[0039] With such an arrangement, the secondary shaking unit can quickly shake the milk that has been initially brewed in the previous process, so that the milk is fully shaken. An adsorption fit can be formed between the magnetic disc 12 and the container containing the milk (e.g., a feeding bottle), thereby fixing the container. The first rotating shaft 13 drives the magnetic disc 12 to shake in the z-axis direction, and the second rotating shaft 14 drives the magnetic disc 12 to shake in the x-axis direction, thereby driving the shaking of the container containing the milk, thereby achieving uniform mixing. At the same time, the sliding base 10 can drive the magnetic disc 12 to translate on the horizontal transverse guide rail 9, thereby facilitating the translation of the container containing the milk to a suitable position in the space, facilitating shaking, and also facilitating rising along the arc-shaped guide rail 3 to remove the brewed feeding bottle. Therefore, the spatial design of each component of the present application is reasonable, the degree of coordination is high, and it is more convenient to use.

[0040] The arc ring 11 comprises an arcuate portion and vertical portions disposed at either end of the arcuate portion. A central hole 19 is provided in the middle of the arcuate portion for connection to the first rotating shaft 13. Each of the two vertical portions has an end hole 20 at its lower portion for connection to the second rotating shaft 14. The second rotating shaft 14 is disposed on the magnetic disc 12 and passes through the center of the disc to enhance its stability. The arcuate portion easily matches the curvature of the bottle, providing a certain limit to prevent the bottle from tipping over.

[0041] The bottom of the sliding base 10 is provided with a bottom slot 18 for engaging with the horizontal transverse guide rail 9 so as to be able to move along the horizontal transverse guide rail 9 . The first rotating shaft 13 is provided above the sliding base 10 and further connected to the arc ring 11 .

[0042] The quantitative milk powder dispensing unit includes a milk powder bin 1, a screw rod 2, a third motor, a fourth motor, a lifting plate 7, and a crank connecting rod 8; the screw rod 2, the lifting plate 7, and the crank connecting rod 8 are arranged below the milk powder bin 1; one end of the lifting plate 7 is hinged to the bottom of the milk powder bin 1, and the other end is connected to the crank connecting rod 8. The third motor is used to drive the crank connecting rod 8 to make the lifting plate 7 reciprocate and rise and fall, thereby causing the milk powder in the milk powder bin 1 to fall to the screw rod 2; the fourth motor is used to drive the screw rod 2 to rotate to quantitatively deliver the target brewing amount of milk powder. Compared with most of the milk powder brewing products on the market, the solution provided by the utility model, in addition to the original initial brewing part, sets up and optimizes the quantitative milk powder dispensing unit, and the quantitative milk powder dispensing unit can complete the quantitative dispensing of milk powder with relatively higher accuracy.

[0043] The initial milk powder brewing unit includes a brewing chamber 22, a constant temperature water tank 21, a water pipe 23 and a milk pipe 5; the constant temperature water tank 21 is connected to the brewing chamber 22 through the water pipe 23, and the opening of the brewing chamber 22 is connected to the milk powder outlet of the quantitative milk powder dispensing unit for initially mixing and brewing milk powder and water; the milk pipe 5 is connected to the brewing chamber 22 for outputting the liquid in the brewing chamber 22.

[0044] A gear 15 is provided at one end of the milk tube 5 connected to the brewing chamber 22. The milk tube 5 passes through the axis of the gear 15 and is connected to the brewing chamber 22. The gear 15 is used to drive the milk tube 5 to rotate in cooperation with the motor drive gear to adjust the position of the outlet end of the milk tube 5.

[0045] A hexagonal column 17 is fixed to the outlet end of the milk delivery tube 5, which is used to push and pull the inlet end of the container containing the milk to complete the closing of the switch.

[0046] Specifically, the automatic milk powder brewing machine also includes an automatic cleaning unit for automatically cleaning the initial milk powder brewing unit. This unit includes a wastewater tank 6 located below the brewing chamber 22. This wastewater tank 6 is equipped with a waste liquid inlet 24 that mates with the milk delivery tube 5 and is used to hold waste liquid after automatic cleaning. After brewing, the machine automatically flushes the interior of the mechanism, effectively reducing the burden of use and cleaning for parents.

[0047] After the initial brewing process in the brewing chamber 22, milk flows into the milking tube 5 and out the water outlet into the feeding bottle below. Once all the milk has flowed into the feeding bottle through the milking tube 5, the gear at the top of the milking tube 5, driven by the servo, rotates a fixed angle, causing the milking tube 5 to rotate to a specific position, with the water outlet of the milking tube 5 directly above the opening of the wastewater tank 6. The water pump then ejects water once more to flush the brewing chamber 22. The wastewater from this flushing process flows through the milking tube 5 and out the water outlet into the wastewater tank 6, thus achieving automatic cleaning of the brewing chamber 22 and collecting the wastewater.

[0048] In some specific embodiments, the automatic milk powder brewing machine includes a shell, and the quantitative milk powder dispensing unit, the primary milk powder brewing unit, the secondary shaking unit and the automatic cleaning unit are all arranged in the shell. Among them, the quantitative milk powder dispensing unit is arranged above the shell, the brewing chamber 22 and the milk delivery tube 5 are arranged below the screw rod 2 of the quantitative milk powder dispensing unit, and the waste water tank 6 is arranged below the milk delivery tube 5 to facilitate the recovery of waste liquid after cleaning. The arc guide rail 3 is arranged on the two opposite side walls of the shell (preferably the side walls perpendicular to the side walls where the quantitative milk powder dispensing unit is located), and the horizontal transverse guide rail 9 is arranged at the bottom of the shell and has a certain distance from the side wall where the quantitative milk powder dispensing unit is located to facilitate the installation of the arc ring 11. The constant temperature water tank 21 is arranged below the lifting plate 7 of the quantitative milk powder dispensing unit, side by side with the waste water tank 6. When a second shaking is required, the bottle is moved to the outlet end of the milk tube 5 by sliding the base 10. After the milk in the brewing chamber 22 enters the bottle, the bottle is moved to a suitable position in the space by sliding the base 10 for easy shaking. After mixing, the horizontal guide rail 9 is moved up along the arc guide rail 3 to take out the bottle.

[0049] The present invention provides an automatic milk powder brewing machine with the following method of use: First, the automatic milk powder brewing machine receives the precise milk powder mass input from a parent terminal or an intelligent AI system. The feed table, driven by a small motor, performs a reciprocating up and down swinging motion, shaking a portion of the milk powder in the milk powder bin 1 to the screw rod 2 below. The screw rod 2 is driven by a stepper motor. The intelligent system converts the required amount of milk powder into the required rotation angle and speed of the stepper motor and converts it into an electrical signal to the stepper motor. The screw rod 2 then rotates to push the milk powder to the brewing chamber 22 below at a certain speed. At the same time, a small water pump on the left side of the brewing chamber 22 pumps boiling water of a suitable temperature from the constant temperature water tank 21 into the brewing chamber 22 through the water pipe 23. The boiling water is then used to flush the milk powder falling from above at a certain speed and water pressure, achieving the initial brewing of the milk powder and boiling water.

[0050] The milk that has been brewed for the first time is then transported by the milk delivery pipe 5. The milk delivery pipe 5 opens the top circular hole of the feeding bottle by rotating the head before delivering milk. Next, the milk can be delivered to the feeding bottle by this circular hole, and then the circular hole is closed after the milk delivery is completed. Subsequently, a small water pump once again pumps boiling water from the constant temperature water tank 21 to the brewing chamber 22, flushes the brewing chamber 22 inner walls and the milk delivery pipe 5 with a certain water pressure, and then the milk delivery pipe 5 rotates the head above the wastewater tank, and the waste water flushed is discharged to the wastewater tank 6, which is then collected by the wastewater tank 6. When the wastewater reaches a certain amount, the guardian manually takes out the wastewater tank 6 and empties it. After the feeding bottle has completed collecting the milk, it just begins to brew the milk for the second time. The multi-axis mobile platform 4 that fixes the feeding bottle will drive the feeding bottle to move horizontally to the right, and is subsequently driven by a plurality of micro-servos so that the feeding bottle is rotated around three XYZ axes, realizing the further sufficient shaking of the milk. After shaking, the platform moves the bottle horizontally to the left, keeping it warm and ready for use. When the caregiver needs to feed the baby, the automatic milk powder dispenser receives the command and lifts the bottle upward via the platform, allowing the caregiver to take the bottle. The caregiver can then feed the baby directly with the prepared milk without having to manually prepare the milk powder.

[0051] In summary, the present invention provides a novel automatic milk powder brewing system. Building on the existing brewing chamber, the system upgrades the powder chamber and its dosing unit, adding a secondary shaking unit and an automatic cleaning unit. This solution delivers high-quality milk and automatically rinses the interior of the system after brewing, effectively reducing the burden on parents regarding use and cleaning.

[0052] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
