Description

Technical Field

[0001] This utility model belongs to the field of milk churning equipment technology, and in particular relates to an automatic milk churning equipment. Background Technology

[0002] When preparing formula for infants, parents mainly rely on manually shaking the bottle to mix the powder with water. Manual shaking makes it difficult to ensure that the powder dissolves completely, and the powder is prone to clumping in the water. Vigorous shaking also introduces too many air bubbles into the milk, which can cause discomfort such as hiccups in infants. The whole process is time-consuming and laborious, and is extremely inconvenient at night or when frequent feedings are needed.

[0003] To address the aforementioned issues, automatic milk churns have emerged on the market. Chinese patent document CN217161875U discloses a baby milk warmer / churner, comprising a base, a lifting assembly, a drive assembly, and a sterilization assembly. The base has a warming groove, and a lifting seat is located on one side of the warming groove. The lifting assembly drives the lifting seat to move up and down relative to the base. A connector is rotatably mounted on the lifting seat and is detachably connected to the baby bottle. The drive assembly is located inside the lifting seat and drives the connector to rotate. The sterilization assembly is located on the bottom surface of the connector. The drive assembly inside the lifting seat drives the connector below the lifting seat to rotate the baby bottle, thereby accelerating the dispersion of milk powder in the water and resulting in a higher quality prepared milk solution.

[0004] However, the aforementioned warming milk churn uses a screw lifting assembly, back plate, and lifting base structure, which makes the whole machine occupy a large space and inconvenient to store; and the drive assembly drives the connector to rotate the entire bottle for stirring, which requires high power and a relatively long stirring time, and may generate more air bubbles due to the rotation of the entire bottle.

[0005] Stirring cups have appeared on the market. Chinese patent document CN208302685U discloses a magnetic stirring cup, which includes an inner liner, a connecting sleeve, a magnetic drive device, and a magnetic rod. The connecting sleeve is adapted to the lower end of the inner liner. The bottom wall of the connecting sleeve has a central hole. The magnetic drive device passes through the central hole and is detachably connected to the connecting sleeve. The magnetic rod is placed at the bottom of the inner liner and is fixed to the magnetic drive device by a magnetic field. After the magnetic drive device is powered on, it drives the magnetic rod to rotate through the attraction between the magnetic drive device and the magnetic rod to achieve the stirring function.

[0006] The above technical solution allows the magnetic drive device to rotate the magnetic rod at the bottom of the inner liner, ensuring thorough mixing of the liquid and effectively reducing the overall footprint of the machine. However, when preparing formula, the bottom of the bottle is typically a curved, convex structure. The magnetic rod itself is a rod-shaped structure, maintaining balance and rotating only within the flat bottom of the inner liner; if the bottom is curved and convex, even with magnetic attraction, the magnetic rod will still deviate to one side, failing to achieve stable stirring. Therefore, after mixing the formula and warm water, the mixture must be transferred to a regular bottle, making the process cumbersome and requiring cleaning of multiple components, including the mixing cup, bottle, and magnetic rod. Utility Model Content

[0007] The purpose of this invention is to provide an automatic milk stirrer that solves the problem that the magnetic rod in the existing magnetic stirring cup is only applicable to the flat-bottomed inner liner, and requires transferring the liquid when preparing milk powder, which makes it cumbersome to use.

[0008] To achieve the above objectives, this utility model provides an automatic milk maker, including a base and a magnetic ring. The top of the base is provided with an inwardly recessed receiving groove for accommodating a milk bottle. The magnetic ring is magnetic and is used to be placed inside the milk bottle. The base is also provided with a motor, and the output shaft of the motor is connected to a magnetic component for driving the magnetic component to rotate around the axis of the output shaft, so as to drive the magnetic ring to rotate synchronously.

[0009] Furthermore, the magnetic ring includes a wrapping ring and a first magnet, the first magnet being disposed within the wrapping ring.

[0010] Furthermore, the wrapping ring is a one-piece molded ring.

[0011] Furthermore, the wrapping ring includes an upper shell and a lower shell, which are closed together to form an annular body.

[0012] Furthermore, the upper and lower shells are made of stainless steel, and the outer surface of the wrapping ring is covered with a silicone layer.

[0013] Furthermore, two first magnets are symmetrically arranged inside the wrapping ring, and a sealing groove is provided inside the wrapping ring. The sealing groove is evenly divided into a number of grooves that are twice the number of grooves, and the two first magnets are symmetrically arranged in two oppositely arranged grooves.

[0014] Furthermore, the output shaft of the motor is connected to a support frame, and the support frame is symmetrically provided with two limiting grooves. One of the limiting grooves is used to limit one of the magnetic components. The limiting groove is open at the bottom and has a cover plate at the top. The bottom of the limiting groove is provided with multiple spaced limiting blocks, and the top surfaces of the multiple limiting blocks are on the same plane to support the magnetic component. The limiting blocks cooperate with the cover plate to limit the magnetic component vertically.

[0015] Furthermore, the inner wall of the limiting groove is provided with a plurality of spaced protrusions for horizontally abutting against the magnetic component in the circumferential direction.

[0016] Furthermore, the base also includes a motor bracket, the top of which has a downwardly recessed cavity. The cavity and the bottom of the receiving groove cooperate to form a cavity for the support frame to rotate. The bottom of the motor bracket has a positioning cavity for fixing the motor. The output shaft of the motor passes through the motor bracket and is connected to the support frame.

[0017] Furthermore, the bottom of the receiving groove has an upward recess in the cavity area to provide clearance space for the support frame.

[0018] The automatic milk churn provided in this embodiment of the present invention has at least the following technical effects: After filling the bottle with formula and warm water, place the magnetic ring inside and tighten the cap. Then, place the bottle in the receiving slot of the base. Because the magnetic ring itself is magnetic, and the base contains magnetic components, the magnetic ring automatically aligns and adjusts to the optimal driving position under magnetic attraction, ensuring stable and reliable transmission. Due to the ring-shaped structure of the magnetic ring, it can be evenly supported on the curved convex surface of the bottle bottom after automatic alignment, maintaining good contact stability.

[0019] When the motor is started, it drives the magnetic component to rotate around the output shaft. This magnetic field causes the magnetic ring to rotate smoothly inside the bottle, creating a uniform vortex. This effectively reduces the formation of air bubbles and promotes rapid and thorough mixing of milk powder and water, improving stirring efficiency.

[0020] After stirring, users simply need to attach a straw to the bottle cap; the magnetic ring can be removed before drinking. After use, the magnetic ring can be washed and sterilized along with the bottle. The process is convenient, eliminating the need to transfer liquids and reducing the number of cleaning parts.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0036] In one embodiment of the automatic milk churn of this utility model, please refer to... Figures 1 to 9 An automatic milk maker includes a base 200 and a magnetic ring 300, used to automatically mix milk powder and water in a baby bottle 100. The top of the base 200 has an inwardly recessed receiving groove 210 for holding the baby bottle 100. The magnetic ring 300 is magnetic and is placed inside the baby bottle 100. A motor 220 is located inside the base 200, and the output shaft of the motor 220 is connected to a magnetic component 230, used to drive the magnetic component 230 to rotate around the axis of the output shaft, thereby driving the magnetic ring 300 to rotate synchronously inside the baby bottle 100.

[0037] Specifically, after filling the bottle 100 with milk powder and warm water, the magnetic ring 300 is placed inside the bottle and the bottle cap is tightened. The bottle 100 is then placed in the receiving slot 210 of the base. Because the magnetic ring 300 is magnetic, and the base 200 contains a magnetic component 230, the magnetic ring 300 automatically aligns and adjusts to the optimal driving position under magnetic attraction, thus ensuring stable and reliable transmission. Due to the ring-shaped structure of the magnetic ring 300, after automatic alignment, it can be balanced and supported on the arc-shaped raised surface at the bottom of the bottle 100, maintaining good contact stability.

[0038] The motor 220 is started, driving the magnetic component 230 to rotate around the output shaft. This magnetic field causes the magnetic ring 300 to rotate smoothly and synchronously inside the bottle, creating a uniform vortex. This effectively reduces the formation of air bubbles and promotes rapid and thorough mixing of milk powder and water, improving stirring efficiency.

[0039] After stirring, users only need to attach a straw to the bottle cap; the magnetic ring 300 can be used directly without removing it. After use, the magnetic ring 300 can be cleaned and sterilized together with the bottle 100. The process is convenient, requiring no liquid transfer and reducing the number of cleaning parts.

[0040] Preferably, the motor 220 is located directly below the receiving groove 210, the output shaft of the motor 220 is connected to the center of the magnetic component 230, and the axis of the output shaft of the motor 220 coincides with the central axis of the receiving groove 210, so that the magnetic ring 300 attracted by the magnetic component 230 is automatically aligned and centered.

[0041] Please refer to Figure 2 The magnetic ring 300 includes a retaining ring 320 and a first magnet 310, which is disposed within the retaining ring 320. The retaining ring 320 separates the magnet 310 from the milk to ensure safe use. The first magnet 310 is magnetic and is used to magnetically attract with the magnetic component 230 in the base.

[0042] Please refer to one embodiment of the wrapping ring 320 of this utility model. Figure 2 The wrapping ring 320 is a one-piece molded ring-shaped plastic part, which is wrapped around the outer surface of the first magnet 310 by a rubber injection molding process.

[0043] For another embodiment of the wrapping ring 320 of this utility model, please refer to... Figure 4 The enclosing ring 320 includes an upper shell 321 and a lower shell 322. The upper shell 321 and the lower shell 322 can be sealed together by snap-fitting, gluing or welding to form a ring body. The first magnet 310 is fixed inside the ring body.

[0044] Optionally, the upper housing 321 and the lower housing 322 are made of plastic.

[0045] Optionally, the upper shell 321 and the lower shell 322 are made of stainless steel, and the outer surface of the ring 320 is covered with a silicone layer. Specifically, the stainless steel material enhances the structural strength of the magnetic ring 300, and the silicone layer separates the shell from the milk, ensuring the safe stirring of the magnetic ring 300.

[0046] Please refer to Figure 2 and Figure 5 The enclosing ring 320 has a sealing groove 330, which can be a complete ring design. The first magnet 310 is a ring-shaped magnet, and the annular sealing groove 330 in the enclosing ring is used to fix the annular first magnet 310. At this time, the polarities of the left and right sides of the annular first magnet 310 are S pole and N pole respectively, and the polarities of the left and right sides of the magnetic component 230 are N pole and S pole respectively. The magnetic poles correspond one-to-one, forming a stable magnetic coupling, which is used to attract the magnetic ring 300 for automatic alignment.

[0047] Alternatively, please refer to Figure 4 and Figure 6 The sealing groove 330 can also be evenly divided into a multiple of two arc-shaped grooves 331. Two first magnets 310 are arc-shaped and symmetrically fixed within two oppositely arranged grooves 331. The polarities of the two first magnets 310 are opposite. Preferably, the sealing groove 330 is equally divided into four grooves 331, with the two first magnets 310 respectively disposed within two non-adjacent and oppositely arranged grooves 331. This ensures that the magnetic ring 300 is subjected to balanced forces at both ends.

[0048] Please refer to Figure 2 , Figure 3 and Figure 7 The base 200 also includes a support frame 240 with a central mounting hole in which the output shaft of the motor 220 is fixed. The support frame 240 has two symmetrically positioned grooves 241 on either side of the mounting hole, each groove 241 fixing a magnetic component 230. The two symmetrically positioned magnetic components 230 generate the same magnetic field strength, and their top surfaces have opposite polarities, thus applying a balanced attraction force to both sides of the magnetic ring 300, ensuring that the magnetic ring 300 maintains stable rotation within the bottle 100.

[0049] Please refer to Figure 7 The support frame 240 has an opening at the bottom of the limiting groove 241 and a cover plate 242 at the top. Multiple spaced limiting blocks 243 are arranged circumferentially at the bottom of the limiting groove 241, with the top surfaces of the multiple limiting blocks 243 on the same plane, used to support the bottom surface of the magnetic component 230. The limiting blocks 243 and the cover plate 242 cooperate vertically to limit the magnetic component 230 from both above and below.

[0050] Please refer to Figure 7The inner wall of the limiting groove 241 is provided with multiple spaced protrusions 244. The protrusions 244 extend horizontally, so that the inner wall of the protrusions 244 abuts against the outer wall of the magnetic component 230. The multiple protrusions 244 are used to circumferentially limit the magnetic component 230 in the horizontal plane. The horizontal extension length of the protrusions 244 is less than the extension length of the top surface of the limiting block 243, pressing the magnetic component 230 into the limiting groove 241 from the opening. The limiting block 243 axially supports and limits the magnetic component 230, and the protrusions 244 horizontally limit the magnetic component 230, effectively preventing the magnetic component 230 from loosening or falling off during high-speed rotation. The magnetic component 230 is preferably square for easy assembly.

[0051] Preferably, the bottom of the protrusion 244 and the limiting block 243 are provided with inclined guide surfaces, which facilitates the magnetic component 230 to be guided and pressed into the limiting groove 241 from the opening along the inclined guide surfaces, and the limiting block 243 supports and limits the magnetic component 230.

[0052] Please refer to Figure 8 and Figure 9 The base 200 also includes a motor bracket 250. The motor bracket 250 has lugs 253 on both sides, and each lug 253 has a first connecting hole 254 extending vertically through it. The bottom of the receiving groove 210 has two connecting posts 211 corresponding to the lugs 253. The bottom of each connecting post 211 extends to the position of the lugs 253, and each connecting post 211 has a second connecting hole 212. The motor bracket 250 is securely installed at the bottom of the receiving groove 210 by bolts passing through the first connecting holes 254 and the second connecting holes 212.

[0053] Please refer to Figure 2 , Figure 3 and Figure 8 The motor bracket 250 has a downwardly recessed cavity 251 at its top, which mates with the bottom of the receiving groove 210 to form a cavity for the support frame 240 to rotate. The bottom of the motor bracket 250 has a positioning cavity 252 for fixing the motor 220. The output shaft of the motor 220 passes through the motor bracket 250 and connects to the support frame 240, driving the support frame 240 to rotate within the cavity. Specifically, the fixed installation of the motor 220 ensures the stability of its output shaft axis, thereby ensuring the stability of the magnetic field generated by the two symmetrically arranged magnetic components 230.

[0054] For further details, please refer to... Figure 2 and Figure 9 The bottom of the receiving groove 210 has an upward-facing recess 213 in the cavity 251 area to provide a space for the support frame 240 to rotate. While ensuring the structural strength of the base 200, the thickness of the bottom of the receiving groove 210 is reduced so that the magnetic component 230 and the magnetic ring 300 are closer together, thereby enhancing the magnetic coupling effect.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
