Description

A milk maker with high-precision dynamic weighing function Technical Field

[0001] This invention relates to the field of maternal and infant equipment technology, and in particular to a formula maker with high-precision dynamic weighing function. Background Technology

[0002] A formula maker is a mother and baby device that automatically mixes, stirs, and dispenses a measured amount of formula powder and water. However, existing formula makers generally suffer from several key issues affecting usability and user experience. The most critical issue, and the primary factor impacting the accuracy of the formula mixing ratio, is insufficient precision in the weighing of the added formula powder and water. Specifically:

[0003] The weighing accuracy of added milk powder is low, resulting in significant dynamic errors. Current milk powder dispensers typically use a weighing sensor below the bottle to monitor the weight of the added ingredients in real time, calculating the total weight to estimate the milk powder amount. This approach suffers from an inherent and difficult-to-overcome dynamic weighing error: the inertia of falling material. When the controller detects that the weighing sensor reading has reached the preset target weight, it immediately issues a stop-addition signal (e.g., closing the water valve or stopping powder dispensing). However, the milk powder that has already left the dispensing port but hasn't yet fallen into the bottle continues to fall due to inertia. The weight of this "material in transit" is not captured by the sensor in real time, leading to a final actual addition amount significantly exceeding the preset target value.

[0004] Secondly, because the density of milk powder is easily affected by factors such as accumulation and clumping, the uniformity and speed of its descent are more difficult to predict, and the error is greater if the amount is excessive. This inaccurate ratio, especially with excessive milk powder, directly affects the concentration of the milk and the nutritional intake of infants, which is the primary defect that urgently needs to be solved in the current technology.

[0005] 2. The large size and difficulty in cleaning of the mixing structure mean that milk powder cannot be completely dissolved. Furthermore, most existing formula makers rely on mechanical mixing blades inside the bottle for mixing. This mixing structure itself requires installation space, increasing the overall size of the equipment. More importantly, the mixing blades and their drive components are in direct contact with the milk, easily leaving milk residue, creating many hard-to-clean areas, and posing a risk of inconvenient cleaning and bacterial growth.

[0006] 3. The milk powder dispensing mechanism is prone to clogging and poor powder dispensing. A common milk powder dispensing mechanism involves a powder leakage hole at the bottom of the milk powder hopper, controlled by a valve or baffle. A major drawback of this structure is its susceptibility to the physical properties of milk powder. Under pressure, milk powder particles can easily form "arches" or "bridges" near the leakage hole, preventing the milk powder from flowing smoothly despite a large amount in the hopper. This necessitates manual intervention (such as tapping or shaking), severely impacting automation and reliability.

[0007] In summary, existing formula preparation machine technology has significant shortcomings in achieving high-precision proportions (especially in milk powder weighing), ease of cleaning, and reliability of milk powder addition. There is an urgent need for an innovative solution to overcome these deficiencies and provide a more accurate, convenient, hygienic, and gentle formula preparation device. Summary of the Invention

[0036] The invention will now be further described with reference to the accompanying drawings.

[0037] As shown in Figure 1, a formula maker with high-precision dynamic weighing function provides formula powder through a powder supply mechanism 2. A dynamic weighing mechanism 3 located below the powder supply mechanism 2 can weigh the entire powder supply mechanism 2 with higher accuracy. Specifically, a weighing sensor 32 supports the entire powder storage chamber 21, which is essentially suspended in the receiving slot 121 of the formula maker housing 12. The powder storage chamber 21 contains formula powder, and the weighing sensor 32 weighs the powder storage chamber 21 and the formula powder in real time. When formula needs to be prepared, the formula powder is discharged from the powder storage chamber 21, causing a change in the value measured by the weighing sensor 32. The decrease in value represents the precise weight of the discharged formula powder. This solution achieves more accurate weighing compared to existing technologies.

[0038] The complete structure of the entire formula maker includes:

[0039] A housing assembly 1 includes a base 11 and a housing 12 disposed on the base 11;

[0040] A powder supply mechanism 2 includes a powder storage bin 21 with a powder feeding screw 22 at the bottom. The powder storage bin 21 is disposed in the receiving groove 121 of the housing 12. The powder feeding screw 22 is connected to a drive assembly 4.

[0041] A dynamic weighing mechanism 3 includes a weighing sensor 32 installed below the powder storage bin 21. The powder storage bin 21 is connected to the housing 12 through the weighing sensor 32. The weighing sensor 32 weighs the entire powder storage bin 21 in real time.

[0042] A mixing and stirring mechanism 5 includes a funnel-shaped mixing chamber 51 and a liquid outlet located below the mixing chamber 51. The mixing chamber 51 is connected to a high-pressure water supply component 6. The powder outlet 231 of the powder storage chamber 21 is correspondingly located above the inner wall of the mixing chamber 51. After the hot water in the mixing chamber 51 is mixed with the milk powder, it falls into the milk bottle from the liquid outlet.

[0043] A water storage mechanism 7 includes a kettle seat 71 mounted on a housing 12, a water storage kettle 72 mounted on the kettle seat 71, and a water supply pipe 73 connected to the water storage kettle 72. The water supply pipe 73 is connected to a high-pressure water supply component 6 and a warm water outlet 74.

[0044] A control panel 8 is electrically connected to the powder supply mechanism 2, the dynamic weighing mechanism 3, the high-pressure water supply component 6, and the water supply pipeline 73. The control panel 8 includes a controller, which receives user input and receives the weight of the powder supply mechanism weighed by the dynamic weighing mechanism 3 in real time, and can control the opening and closing of the powder supply mechanism, the high-pressure water supply component 6, and the water supply pipeline 73.

[0045] The dynamic weighing mechanism 3 also includes a weighing fixing plate 31 disposed below the powder storage bin 21. The weighing fixing plate 31 has a sensor lower mounting seat 33 protruding upward, and the bottom of the powder storage bin 21 has a sensor upper mounting seat 34 protruding downward. The two ends of the weighing sensor 32 are fixedly connected to the sensor lower mounting seat 33 and the sensor upper mounting seat 34 respectively.

[0046] This solution is a formula maker with high-precision dynamic weighing function. The core technology principle is "source weighing" combined with "non-contact fluid stirring", which systematically solves the three major pain points of existing formula makers.

[0047] 1. The precise dynamic weighing principle solves the problem of inaccurate milk powder weighing:

[0048] The source weighing method is as follows: Unlike traditional weighing under the bottle, this invention installs a weighing sensor 32 directly below the powder storage hopper 21, measuring the weight change of the entire hopper 21 (including all the milk powder inside) in real time. When the control system needs to add a certain weight (e.g., 120g) of milk powder, it controls the feeding screw 22 to start working. The weighing sensor 32 continuously monitors the weight loss in the powder storage hopper 21. Once the weight loss reaches the target value, the feeding screw 22 immediately stops. At this point, even if a small amount of milk powder is "in transit," it has already been deducted from the hopper 21. Therefore, the net weight of the milk powder that finally falls into the bottle is the target weight, fundamentally eliminating the excess error caused by the inertia of "materials in transit."

[0049] 2. Uniform mixing solves the problems of uneven stirring and difficulty in cleaning:

[0050] The solution abandons traditional mechanical stirring blades and uses high-pressure water jets for mixing. The high-pressure water supply component 6 ejects hot water at high speed from the annular flow channel 511, impacting the inner wall of the funnel-shaped mixing chamber 51, creating turbulence and vortices. Venturi effect / jet mixing: the falling high-speed water flow ensures that the milk powder and water are fully and gently mixed and dissolved in the high-speed turbulence, preventing clumping. Adopting a non-contact design, no mechanical parts come into contact with the milk during the mixing process. The inner wall of the mixing chamber 51 is smooth and has no dead corners, requiring only rinsing for cleaning, greatly improving hygiene.

[0051] 3. Reliable powder dispensing solves clogging problems:

[0052] The milk powder is supplied via a screw-driven feeding system, with the feeding screw 22 serving as the core powder dispensing mechanism. The rotation of the feeding screw 22 applies a continuous, directional thrust to the milk powder, effectively breaking up any "arching" or "bridging" phenomena caused by the pressure of milk powder accumulation, ensuring smooth and reliable powder dispensing. Furthermore, the dispensing volume is controllable: the volume of milk powder pushed by the feeding screw 22 per revolution is fixed. By controlling the number of revolutions / time of the motor 41, the dispensing volume can be precisely controlled, providing double assurance in conjunction with the source weighing system.

[0053] The main technological advantages are as follows:

[0054] 1. The formula has extremely high precision, which fundamentally eliminates dynamic weighing errors and achieves high-precision control of the amount of milk powder added. This ensures that the concentration of the milk liquid prepared each time conforms to the preset formula, guaranteeing the accurate and healthy nutritional intake of infants and young children.

[0055] 2. Excellent hygiene and ease of cleaning: The absence of mechanical stirring blades eliminates cleaning dead spots and the risk of bacterial growth. The simple, smooth mixing chamber structure is easy to rinse, meeting the high hygiene requirements of baby products. Users do not need to disassemble and clean complex stirring components, significantly improving the user experience.

[0056] 3. Reliable operation and smooth powder dispensing: The screw-type feeding mechanism effectively avoids milk powder blockage and arching problems, ensuring the continuity and automation reliability of the milk preparation process, and eliminating the need for manual intervention to tap the powder hopper.

[0057] 4. Compact and Integrated Structure: The removal of components such as the stirring motor 41 and blades results in a more compact overall structure. The weighing, powder supply, water supply, and stirring functions are highly integrated into a single device, potentially resulting in a smaller size while offering greater functionality.

[0058] It should be noted that the water storage tank 72 in this solution can be either a thermostatic kettle or a kettle paired with an instant heating module. If it is a thermostatic kettle, the kettle boils cold water and keeps it at 40-45℃. When in use, the water pump 63 pumps out the warm water from the thermostatic kettle and supplies it to the high-pressure water supply component 6 and the warm water outlet 74. Another solution is to use a kettle and an instant heating module to achieve timely supply of warm water. The kettle boils tap water and allows it to cool naturally. When in use, the water pump 63 pumps out the water from the kettle and reheats it through an instant heater before supplying it.

[0059] An annular flow channel 511 is provided on the inner wall of the mixing chamber 51 along the high pressure outlet 512 of the high pressure water supply component 6.

[0060] The purpose of the annular flow channel 511 is to allow the hot water sprayed from the high-pressure outlet 512 to flow down the inner wall of the mixing chamber 51 over a wide area, thereby increasing the mixing area. The mixing chamber 51 is preferably eccentrically funnel-shaped, which increases the flow path of the milk and improves the degree of milk powder dissolution. The bottom of the mixing chamber 51 is equipped with guide ribs 52 to ensure the milk drips linearly, preventing spillage.

[0061] One end of the powder feeding screw 22 is driven to rotate by the drive assembly 4. The powder storage bin 21 includes a powder outlet channel 211 into which the powder feeding screw 22 can be inserted. The end of the powder outlet channel 211 is fitted with a powder outlet cover 23 that can support the powder feeding screw 22. The bottom of the powder outlet cover 23 is provided with a powder drop hole.

[0062] The powder feeding screw 22 is a trumpet-shaped screw. The threaded section inside the powder storage bin 21 is thinner, while the threaded section in the powder outlet channel 211 is thicker. The advantage of this design is that when conveying milk powder, the thinner threaded section carries the milk powder to the powder outlet channel 211 with lower resistance, resulting in a smoother process. The powder feeding screw 22 is driven to rotate by the drive assembly 4, which first conveys the milk powder from the powder storage bin 21 to the powder outlet channel 211, and then it falls from the powder drop hole at the bottom of the powder outlet cover 23. The conveying process ends when the drive assembly 4 stops.

[0063] The drive assembly 4 includes a motor 41, a first bevel gear 42 fixedly connected to the output shaft of the motor 41, and a second bevel gear 43 meshing with the first bevel gear 42. The second bevel gear 43 is embedded in the powder storage bin 21 through a rolling bearing 44. One end of the powder feeding screw 22 is fixedly connected to the second bevel gear 43. The motor 41 is fixedly mounted on a motor 41 mounting plate, and the motor 41 mounting plate is fixedly mounted below the powder storage bin 21.

[0064] The drive assembly 4 drives the first bevel gear 42 to rotate via the motor 41, the first bevel gear 42 drives the second bevel gear 43 to rotate, and the second bevel gear 43 drives the powder feeding screw 22 to rotate. The whole process is stable and smooth.

[0065] The high-pressure water supply component 6 includes a water inlet 61 disposed on the housing 12. The water inlet 61 is connected in sequence to a water meter 62, a water pump 63 and a solenoid valve 64 via a water pipe. The water pipe is connected to a high-pressure water outlet 512 that is connected to the mixing and stirring mechanism 5.

[0066] The water meter 62 can precisely control the supply of hot water, and the water pump 63 and solenoid valve 64 can work together to achieve high-pressure water supply.

[0067] The base 11 is equipped with a bottle holder 111 located below the liquid outlet and a water bottle holder 112 located below the warm water outlet 74. The bottle holder 111 is used for the baby bottle to receive milk, and the water bottle holder 112 is used for the water bottle to receive hot water.

[0068] The bottle holder 111 can be tilted, allowing the bottle to be tilted when dispensing milk. When the bottle is placed on the holder, the milk flowing from the spout falls onto the bottle wall. This structure is similar to the principle of reducing foam when pouring beer along the cup wall; the milk first contacts the bottle wall and then flows down along the inner wall, effectively reducing foaming. The bottle holder 111 in this design can be fixedly connected to the base 11, for example, by plastic bolts, or it can be a detachable design.

[0069] The top of the powder storage hopper 21 is equipped with a powder filling cover.

[0070] The top of the mixing chamber 51 is provided with an exhaust cover 53, and an exhaust gap 531 is provided between the exhaust cover 53 and the milk maker housing 12.

[0071] The exhaust cover 53 is directly placed on top of the mixing chamber 51 and can be easily removed to completely discharge water vapor. The extended raised part of the exhaust cover 53 forms an exhaust gap 531 between itself and the milk maker housing 12, allowing water vapor during the milk making process to be discharged directly from the exhaust gap 531, thus avoiding the formation of water droplets and mold growth.

[0072] A water tank 9 is also connected to the outside of the housing 12 via a water pipe. The water tank 9 is used to supply water to the water storage tank 72.

[0073] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
