Description

Technical Field

[0001] This invention relates to the field of breast pump technology, and more specifically to an intelligent breast pump with an adjustment mechanism. Background Technology

[0002] A baby shaker is a small household appliance specifically designed for preparing formula milk powder. It simulates manual shaking to quickly and evenly mix the powder with water, preventing lumps and air bubbles. Compared to hand shaking, it allows for more precise control of the shaking intensity and time, ensuring the powder dissolves fully while minimizing air contamination. This reduces the risk of gas in babies after feeding and makes preparing formula at night more time-saving and effortless.

[0003] CN221180235U discloses a tilting milk shaker. This shaker features a tilted section within its housing, and a shaking rack assembly is positioned within this tilted section. The shaking rack assembly is also tilted on the shaker housing. During shaking, the bottle is fixed to the shaking rack assembly, and a drive component rotates the assembly circumferentially. This rotation of the bottle, relative to the tilted position on the shaker housing, causes the milk to move up and down along the inner sidewall of the bottle, preventing milk powder from accumulating at the bottom and clumping. This achieves the effect of hand-shaking for mixing milk. By fixing the tilted section within the housing and rotating the shaking rack assembly within this section, the bottle rotates around its own axis while in a fixed tilted position. This reduces the problem of milk powder accumulating at the bottom of the bottle over time.

[0004] The publication number CN117017090B discloses an intelligent baby shaker with an adjustment mechanism, including a housing, a shaking component, and a drive component. The shaking component is disposed on the housing and includes an upper disc, a lower disc, and multiple clamping plates. The top of the lower disc is inclined and has a magnetic element. The bottom of the upper disc is connected to the top of the lower disc, and the centers of the lower disc and the upper disc do not overlap. The clamping plates are disposed on the upper disc for clamping the baby bottle. The drive component is located inside the housing and includes a drive motor, a transmission shaft, and a turntable. The drive motor drives the turntable to rotate through the transmission shaft. A magnetic element is disposed inside the turntable, and the lower disc is magnetically connected to the turntable. The lower and upper discs form an eccentric rotating structure. Combined with the tilted lower disc at the top, this causes the bottle's center of gravity to shift and tilt during the shaking process, increasing the amplitude of the shaking and improving the mixing effect. However, the tilt angle in this design still comes from a fixed inclined plane. Once the tilt angle is determined by the structure, it cannot be matched to the milk volume, bottle shape, or shoulder position in subsequent operations. This leads to a more prominent contradiction: revolution has a stronger liquid turbulence than rotation, but precisely because the turbulence is stronger, the highest liquid level rise boundary is also more sensitive to the tilt angle. When the milk volume is large and the bottle is tall, a fixed larger tilt angle can easily cause milk to splash onto the bottle shoulder, nipple holder, or near the bottle mouth during revolution, increasing the risk of spillage, seepage, and liquid buildup on the bottle walls. When the milk volume is small and the bottle is short, a fixed smaller tilt angle may result in insufficient liquid turbulence, and residual powder at the bottom and powder-covered areas on the bottle shoulder may not be adequately cleaned. Therefore, this design still has room for improvement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an intelligent milk shaker that can adjust the tilt of the revolution according to different milk volumes, in order to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent milk shaker with an adjustment mechanism, comprising a housing, wherein a shaking component and a driving component for driving the shaking component are provided inside the housing, the shaking component includes a milk shaker frame disposed inside the housing and a mounting base connected to the driving component, characterized in that: an adjustment mechanism capable of adjusting the rotation angle of the milk shaker frame is provided between the milk shaker frame and the mounting base, the housing is provided with a locking mechanism capable of locking the milk shaker frame, and a control mechanism is provided on one side of the milk shaker frame of the housing, wherein the control mechanism, the locking mechanism, and the adjustment mechanism are linked to enable the control mechanism to automatically adjust and lock the adjustment mechanism according to the current liquid level.

[0007] The above technical solution includes a shaking component and a driving component for the shaking component inside the housing. The shaking component includes a shaking rack inside the housing and a mounting base connected to the driving component. An adjustment mechanism for adjusting the rotation angle of the shaking rack is provided between the shaking rack and the mounting base. The housing is equipped with a locking mechanism for locking the state of the shaking rack. A control mechanism linked to the locking mechanism and the adjustment mechanism is also provided on one side of the housing near the shaking rack. The control mechanism can automatically adjust the angle and lock the adjustment mechanism according to the current liquid level. It can adapt to different milk volumes. When the milk volume is large, the tilt angle can be adjusted to be smaller. When the milk volume is small, the tilt angle can be adjusted to be larger to increase the liquid turbulence and allow the residual powder at the bottom of the bottle and the powder hanging on the bottle shoulder to be more thoroughly rinsed.

[0008] The aforementioned intelligent milk shaker with an adjustment mechanism can be further configured as follows: the adjustment mechanism includes adjustment wheels disposed on both sides of the mounting base; the milk shaker frame is connected to the mounting base via an angle adjustment seat; the adjustment wheel is provided with a rotating shaft; the rotating shaft is fixedly connected to the angle adjustment seat; the milk shaker frame and the angle adjustment seat are rotatably connected via a first rotary bearing; an adjustment motor is provided on one side of the rotating shaft of the adjustment wheel; the adjustment motor can drive the adjustment wheel to drive the angle adjustment seat and the milk shaker frame to swing for angle adjustment; and the locking mechanism can lock the rotation state of the adjustment wheel.

[0009] The above technical solution achieves tilt adjustment by adjusting the motor-driven adjustment wheel and the angle adjustment seat in a coordinated manner. During use, the adjustment motor drives the angle adjustment seat to swing through the adjustment wheel to adjust the angle. The mounting base serves as the housing for both the adjustment motor and the shaking frame. The shaking frame is connected to the adjustment motor via a rotating shaft, and the shaking frame and the angle adjustment seat are rotatably connected via a first rotating shaft. The drive assembly drives the shaking frame to rotate. This structure avoids interference between the adjustment drive of the shaking frame and the drive assembly, allowing the shaking frame to be adjusted in angle and rotated via the drive assembly.

[0010] The aforementioned intelligent milk shaker with an adjustment mechanism can be further configured as follows: the locking structure includes magnetic posts fixedly installed inside the housing on both sides of the milk shaker frame; each magnetic post is fitted with a pressing ring; the pressing ring is placed on the outer periphery of the milk shaker frame and forms an active space for the milk shaker frame to swing; both sides of the pressing ring are provided with magnetically connected ear sleeves attached to the magnetic posts; the bottom of the magnetic posts is provided with a magnetically attracted ring; the adjustment wheel is a ratchet; both sides of the adjustment wheel are provided with pawls that are normally engaged and locked with the adjustment wheel; the pressing ring can press the pawls to release the ratchet lock after being magnetically attracted by the magnetic posts.

[0011] Using the above technical solution, the magnetic ear sleeve is mounted on a magnetic post. The bottom of the magnetic post has a magnetic ring that generates a magnetic attraction when energized. The adjusting wheel adopts a ratchet structure, and there are pawls on both sides of the adjusting wheel that are normally engaged and locked with the adjusting wheel. When the pressing ring moves under the magnetic attraction of the magnetic post, it can press the pawls to release the ratchet from its locked state. Under normal conditions, the state of the adjusting wheel can be stably fixed by the engagement of the pawls and the ratchet, which prevents the tilt angle from shifting unexpectedly during the milk shaking process and ensures the consistency of the shaking effect. When the angle needs to be adjusted, the pressing ring can be moved by the attraction force generated by the energized magnetic ring, which will simultaneously trigger the pawls to unlock.

[0012] The aforementioned intelligent milk shaker with an adjustment mechanism can be further configured as follows: the control mechanism includes a mounting plate disposed on one side of the milk shaker, a control chip is fixedly mounted on the mounting plate, a connection end is provided on one side of the control chip, the connection end is electrically connected to the adjustment motor and the magnetic column respectively, the housing is located on the outer periphery of the milk shaker and a plurality of liquid level sensors are provided along the vertical direction of the milk shaker to form a plurality of liquid level intervals, the liquid level sensors are electrically connected to the control chip as signal input.

[0013] By adopting the above technical solution and using the control structure of the liquid level sensor, the current liquid level range in the bottle can be identified by the patch sensors at different positions, providing an accurate liquid level signal reference for the control chip. This allows the control chip to output signals according to preset parameters, and to control the magnetic column to be energized and unlocked, and to adjust the angle of the motor. The multi-level liquid level range setting also makes the angle adjustment more adaptable and matches the shaking requirements for different milk volumes.

[0014] The aforementioned intelligent milk shaker with an adjustment mechanism can be further configured such that: the magnetic suction post located between the magnetic ear and the magnetic ring is provided with a first reset spring that allows the magnetic ear to reset after power failure; and the magnetic suction post located at the upper end of the magnetic ear is provided with an upper limit position that restricts the position of the magnetic ear and the pressing ring.

[0015] Using the above technical solution, when the magnetic ring loses its magnetic attraction due to power failure, the first reset spring can automatically push the magnetic connecting ear and the pressing ring to move upward and reset, allowing the pawl to return to the meshing and locking state with the ratchet. No additional reset drive component is required. At the same time, the upper limit structure can limit the upward movement of the pressing ring, preventing the pressing ring from shifting and falling off or being excessively raised, which would affect the triggering of subsequent unlocking actions and improve the stability of the locking mechanism.

[0016] The aforementioned intelligent milk shaker with an adjustment mechanism can be further configured such that: the mounting base has an embedded mounting groove for mounting an angle adjustment seat, and the bottom of the housing has a fixed mounting structure located between the mounting base and the drive assembly.

[0017] The above technical solution provides an embedded mounting groove for the angle adjustment seat, which avoids interference between the angle adjustment seat and the mounting seat when the angle needs to be adjusted. The fixed mounting structure between the mounting seat and the drive assembly enhances the stability of the mounting seat by connecting it to the bottom of the housing.

[0018] The aforementioned intelligent milk shaker with an adjustment mechanism can be further configured such that: the fixed installation structure includes a fixed installation plate disposed between the drive component and the mounting base; the surface of the fixed installation plate is provided with a plurality of fixed posts; a fixed block is provided at the end of each fixed post away from the guide installation plate; the mounting base is provided with a circular installation groove; and the fixed block is placed in the circular installation groove and fixedly connected to the circular installation groove.

[0019] By adopting the above technical solution, the combination of the fixing column, fixing block and circular mounting groove improves the connection between the mounting base and the bottom of the shell. Compared with the single center connection method, the force distribution is better and can reduce the eccentric shaking of the mounting base during milk shaking.

[0020] The aforementioned intelligent milk shaker with an adjustment mechanism can be further configured as follows: the milk shaker includes an upper frame and a lower frame. The upper end of the upper frame is provided with a ball joint mounting groove facing the side wall of the housing. A universal ball joint is provided in the ball joint mounting groove. A first universal arm is provided at one end of the universal ball joint facing the side wall of the housing. A second universal arm is vertically hinged to the first universal arm. A mounting block for mounting the second universal arm is provided on the side wall of the housing. An axially formed waist-shaped groove is provided on the mounting block. The end of the second universal arm away from the first universal arm is placed in the waist-shaped groove and slidably connected to the waist-shaped groove. A second rotary bearing is horizontally installed on the inner wall of the upper frame. A plurality of first elastic plates are provided on the outer periphery of the second rotary bearing. A plurality of second elastic plates are provided on the inner wall of the lower frame.

[0021] Using the above technical solution, the milk shaker includes a separate upper frame and a lower frame. The upper frame has a ball joint mounting groove on its upper end facing the side wall of the housing. A universal ball joint is fitted into the groove, and a first universal arm is connected to the end of the universal ball joint facing the side wall of the housing. The first universal arm and a second universal arm are vertically hinged. A mounting block for mounting the second universal arm is provided at a corresponding position on the side wall of the housing. The mounting block has an axially formed waist-shaped groove. The end of the second universal arm away from the first universal arm is placed in the waist-shaped groove and can slide along the groove. A second universal arm is horizontally mounted on the inner wall of the upper frame. The rotating bearing has several first elastic plates on its outer periphery and several second elastic plates on the inner wall of the lower frame, forming auxiliary support for the upper part of the milk shaker. The second rotating shaft ensures that the rotation of the milk bottle on the upper frame is not interfered with. At the same time, this structure ensures that the upper and lower frames are coaxial when the angle of the milk shaker is adjusted. The first and second elastic plates can reduce the shaking amplitude during the milk shaker operation and can also adapt to milk bottles of different sizes and specifications, reducing the risk of scratches on the outer wall and unstable clamping during the milk bottle clamping process.

[0022] The aforementioned intelligent milk shaker with an adjustment mechanism can be further configured as follows: the drive assembly includes a first connecting column located on one side of the upper frame, a drive motor located at the bottom of the first connecting column, a first synchronous wheel installed at the output end of the drive motor, a second synchronous wheel located at the bottom of the guide mounting plate, the first synchronous wheel and the second synchronous wheel being connected by a synchronous belt, a drive shaft located at the center of the second synchronous wheel, and the end of the drive shaft being fixedly connected to the lower frame.

[0023] Using the above technical solution, a drive motor is provided at the bottom of the first connecting column, a first synchronous wheel is installed at the output end of the drive motor, a second synchronous wheel is provided at the bottom of the housing on the guide mounting plate, the first synchronous wheel and the second synchronous wheel are connected by a synchronous belt, a drive shaft is provided at the center of the second synchronous wheel, the end of the drive shaft is fixedly connected to the lower frame, and the power is directly transmitted to the lower frame of the milk shaker through the drive shaft, so that the milk shaker can be shaken stably to complete the circumferential shaking action.

[0024] The aforementioned intelligent milk shaker with an adjustment mechanism can be further configured such that: a first control switch for controlling the opening and closing of the drive motor is provided at the end of the first connecting column away from the drive motor.

[0025] Using the above technical solution, the first control switch is located at the end of the first connecting column away from the drive motor, controlling the start and stop of the drive motor. The operator can control the start and stop of the milk shaker as needed.

[0026] The beneficial effects of the present invention are as follows: By setting a control mechanism that is linked to the locking mechanism and the adjustment mechanism in the housing, the liquid level sensor arranged vertically along the milk shaker collects the current liquid level information of the milk bottle, and the control chip automatically drives the adjustment motor to adjust the tilt angle of the milk shaker and triggers the locking mechanism to lock, so that the milk shaker can adaptively adjust the revolution tilt angle according to different milk volumes.

Detailed Implementation

[0028] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0029] according to Figures 1 to 6 As shown, this embodiment of an intelligent milk shaker with an adjustment mechanism mainly consists of three parts: a base, a shaking component 2, and a drive component 3. The base is the main support of the whole machine. The drive component 3 is fixedly arranged inside the base. The shaking component 2 is installed above the drive component 3. The shaking component 2 includes a milk shaker 43 and a mounting base 4. The mounting base 4 is fixedly connected to the drive component 3. An adjustment mechanism is provided between the milk shaker 43 and the mounting base 4 to adjust the rotational tilt angle of the milk shaker 43 relative to the mounting base 4. A locking mechanism is provided inside the housing 1 to fix the tilt angle of the milk shaker 43 in the working state. A control mechanism is also provided on one side of the milk shaker 43 in the housing 1, which is linked with the locking mechanism and the adjustment mechanism to automatically complete the angle adjustment and locking according to the liquid level signal.

[0030] The shaking rack 43 is rotatably connected to the mounting base 4 via the first rotary bearing 8, so that the shaking rack 43 can swing around the bearing axis when the angle is adjusted, and when the driving component 3 drives the shaking to be even, the shaking rack 43 can independently complete the circumferential rotation with the lower frame 26. The driving of the adjustment mechanism and the rotation output of the driving component 3 are independent of each other, and there is no motion interference.

[0031] Regulation mechanism The adjustment mechanism consists of an adjustment wheel 5, an angle adjustment seat 6, and a first rotary bearing 8 installed on both sides of the mounting base 4. The angle adjustment seat 6 is embedded in the inner mounting groove 20 of the mounting base 4. The rotating shaft 7 of the adjustment wheel 5 passes through the angle adjustment seat 6 and is fixedly connected to the milk shaker 43. The milk shaker 43 and the angle adjustment seat 6 are rotatably connected through the first rotary bearing 8. The milk shaker 43 can swing around the axis of the bearing in the angle adjustment seat 6. An adjustment motor 9 is installed on the side of the rotating shaft 7 near the adjustment wheel 5. The output of the adjustment motor 9 drives the adjustment wheel 5 to rotate, thereby driving the angle adjustment seat 6 and the milk shaker 43 to complete the tilt angle adjustment.

[0032] During operation, the control mechanism outputs a command based on the signal from the liquid level sensor 17, driving the adjustment motor 9 to rotate at a corresponding angle. The adjustment motor 9 drives the milk shaker 43 to swing around the axis of the first rotating bearing 8 to the target tilt position via the rotating shaft 7. After the tilt angle is adjusted, the locking mechanism locks the adjustment wheel 5, so that the milk shaker 43 maintains the tilt angle without shifting during subsequent shaking.

[0033] The mounting base 4 has an embedded mounting groove 20 for the angle adjustment seat 6 to be embedded in, so that the angle adjustment seat 6 does not interfere with the movement of the mounting base 4 during the tilt adjustment swing. The mounting base 4 and the drive assembly 3 are provided with a fixed mounting structure to enhance the connection stability between the mounting base 4 and the bottom of the housing 1 and to avoid the mounting base 4 from eccentric shaking during the shaking process.

[0034] Locking mechanism The locking mechanism consists of magnetic posts 10, pressing rings 11, magnetic connecting ears 12, magnetic rings 13, and pawls 14, all fixedly installed on both sides of the breast pump 43. The pressing rings 11 are fitted around the magnetic posts 10, positioned outside the breast pump 43, and maintain a certain gap between them, allowing the breast pump 43 to swing freely without interference during tilt adjustment. The pressing rings 11 are fitted onto the magnetic posts 10 via magnetic connecting ears 12 on both sides. The magnetic rings 13 at the bottom of the magnetic posts 10 are responsible for engaging when energized or releasing when de-energized. The adjusting wheel 5 adopts a ratchet structure, with a set of pawls 14 on each side that normally engage with it. Normally, the pawls 14 remain engaged with the ratchet, mechanically locking the adjusting wheel 5 and maintaining a stable tilt angle for the breast pump 43.

[0035] When the tilt angle needs to be adjusted, the magnetic ring 13 is energized to generate a magnetic field, which pulls the pressing ring 11 downwards via the magnetic connecting ear 12. After the pressing ring 11 moves down, it presses down on the pawl 14, causing the pawl 14 to disengage from the ratchet tooth surface and releasing the ratchet lock. At this time, the adjusting motor 9 can drive the adjusting wheel 5 to rotate normally to complete the tilt angle adjustment. After the adjustment is in place, the magnetic ring 13 is de-energized, the magnetic attraction disappears, and the pressing ring 11 returns to its position along the magnetic column 10 under the elastic force of the first return spring 18. The pawl 14 re-engages with the ratchet, and the outer periphery returns to the locked state. The whole process is automatically coordinated by the control mechanism and does not require manual operation. In actual use, the magnetic ring 13 is fitted with an isolation sleeve to avoid affecting other components in the housing 1. This application is for better display of the internal structure, and this setting is not marked as a conventional technical means.

[0036] The magnetic column 10 is located between the magnetic connecting ear 12 and the magnetic ring 13 and is equipped with a first return spring 18. After power is cut off, the spring provides a continuous restoring force to ensure that the pressing ring 11 can reliably move upward and reset. The magnetic column 10 is located at the upper end of the magnetic connecting ear 12 and is equipped with an upper limit position 19 to constrain the maximum upward movement position of the pressing ring 11 and the magnetic connecting ear 12, so that the spring compression is kept within a reasonable range, which helps to improve the stability of the locking mechanism.

[0037] Control mechanism The control mechanism consists of a mounting plate installed on one side of the milk shaker 43 and a control chip 15 fixed thereon. The control chip 15 has a connection terminal 16 on one side, which is electrically connected to the regulating motor 9 and the magnetic column 10 to form an output path for the control signal. Inside the housing 1, a number of liquid level sensors 17 are arranged sequentially around the outer periphery of the milk shaker 43 and along the vertical direction of the milk shaker 43. Each sensor corresponds to a different liquid level recognition range. All liquid level sensors 17 are electrically connected to the control chip 15 as the input source for the liquid level signal. The liquid level sensors 17 are installed on one side of the milk shaker 43 through an regulating mounting plate and do not interfere with the revolution of the milk shaker 43.

[0038] During operation, the liquid level sensor 17 continuously detects the current liquid level range in the bottle and transmits the signal to the control chip 15. The housing 1 has a mounting cavity on one side of the shaker 43 for the independent installation of the control chip 15. Wiring holes are provided on the side wall of the mounting cavity. In this embodiment, the liquid level sensor 17 is a photoelectric liquid level sensor, which is essentially a trigger switch and also a non-contact sensor. The shaker 43 has several detection slots for the sensor to detect. After the sensor is triggered, it sends a signal to the control chip 15, and the control chip 15 outputs corresponding control commands according to the liquid level range. The magnetic column 10 is unlocked and the motor 9 is rotated via the connection end 16, respectively, to complete the automatic adjustment of the tilt angle. The detection step is performed when the bottle is placed in, which detects the liquid level of the bottle in a horizontal state. After the detection is completed, the tilt angle is adjusted. After the tilt angle is in place, the control chip 15 cuts off the power to the magnetic column 10, and the pawl 14 re-engages the ratchet after the spring returns to its original position, completing the automatic locking. The entire adjustment process is uniformly coordinated by the control chip 15. The motor 9 and the locking mechanism work together in sequence without user intervention, so that the shaker can adaptively adjust the working tilt angle according to different milk volume conditions, making the operation relatively simple.

[0039] Fixed installation structure A fixed mounting structure is provided between the mounting base 4 and the drive assembly 3, which is composed of a fixed mounting plate 21, a fixed post 22 and a fixed block 23. The fixed mounting plate 21 is located between the drive assembly 3 and the mounting base 4. Several fixed posts 22 are evenly distributed on the surface of the fixed mounting plate 21. Each fixed post 22 has a fixed block 23 at the end away from the fixed mounting plate 21. A circular mounting groove 24 is correspondingly opened on the mounting base 4. The fixed block 23 is embedded in the circular mounting groove 24 and fixedly connected to it.

[0040] With the cooperation of the fixed column 22, the fixed block 23 and the circular mounting groove 24, the mounting base 4 and the bottom of the housing 1 form a multi-point distributed connection. The uniformity of force distribution is relatively better than that of a single central connection method, which helps to reduce the eccentric shaking of the mounting base 4 during the shaking process and improve the overall structural stability.

[0041] Breast Shaker 43 Structure The milk shaker 43 consists of an upper frame 25 and a lower frame 26. The upper frame 25 has a ball joint mounting groove 27 facing the side wall of the housing 1. A universal ball joint 28 is installed in the ball joint mounting groove 27. The universal ball joint 28 can deflect in all directions within the groove, providing a flexible hinge point for the upper frame 25. The end of the universal ball joint 28 facing the side wall of the housing 1 extends into a first universal arm 29. The first universal arm 29 is connected to the second universal arm 30 through a vertical hinge, forming a two-stage hinge transmission joint. An axially shaped groove 32 is provided on the mounting block 31 on the side wall of the housing 1. The free end of the second universal arm 30 is placed in the waist-shaped groove 32 and forms a sliding connection with the waist-shaped groove 32. The axial length of the waist-shaped groove 32 accommodates the change of the support point position of the milk shaker 43 at different tilt angles, so that the movement path of the upper frame 25 is constrained when the angle is adjusted, and the overall movement is relatively stable and reliable.

[0042] A second rotary bearing 33 is installed horizontally on the inner wall of the upper frame 25. Several first elastic plates 34 are evenly distributed on the outer periphery of the second rotary bearing 33 to support and adapt to the upper outer periphery of the bottle. When the drive assembly 3 drives the lower frame 26 to rotate, the second rotary bearing 33 rolls synchronously with the bottle, so that the upper frame 25 is not affected by the rotational torque, which helps to reduce wear and operating noise caused by friction. At the same time, it ensures that the upper frame 25 and the lower frame 26 remain coaxial when the angle of the shaker 43 is adjusted. Several second elastic plates 35 are provided on the inner wall of the lower frame 26, which fit against the lower outer wall of the bottle. The elastic plates can be adapted to bottles with different outer diameters. The pressure on the bottle surface is relatively dispersed during the clamping process, which is less likely to cause damage to the bottle.

[0043] Driver Component 3 The drive assembly 3 includes a first connecting post 36 disposed on one side of the upper frame 25 inside the housing 1. A drive motor 37 is fixedly installed at the bottom of the first connecting post 36. A first synchronous pulley 38 is installed on the output shaft of the drive motor 37. A second synchronous pulley 39 is provided inside the housing 1 near the bottom of the fixed mounting plate 21. The first synchronous pulley 38 and the second synchronous pulley 39 are connected by a synchronous belt 40 to transmit the rotational output of the drive motor 37 to the second synchronous pulley 39. A transmission shaft 41 is provided at the center of the second synchronous pulley 39. The end of the transmission shaft 41 is fixedly connected to the lower frame 26. The drive motor 37 drives the lower frame 26 to rotate circumferentially through the synchronous belt 40, thereby driving the milk shaker 43 and the milk bottle to complete the revolution and shaking action.

[0044] A first control switch 42 is provided at the end of the first connecting column 36 away from the drive motor 37. The operator controls the start and stop of the shaking action by controlling the start and stop of the shaking action through the first control switch 42. The operation logic is relatively intuitive.

[0045] Usage process (1) Add an appropriate amount of warm water to the bottle, add milk powder according to the formula ratio, tighten the nipple and place the bottle into the lower frame 26 of the bottle shaker 43, and fix it by the second elastic plate 35. At the same time, make sure that the first elastic plate 34 of the upper frame 25 supports the upper part of the bottle.

[0046] (2) The liquid level sensor 17 detects the current liquid level range in the bottle and transmits the signal to the control chip 15. The control chip 15 outputs a command, the magnetic ring 13 is energized, the pressing ring 11 moves down to press the pawl 14 to release the ratchet lock, and the adjusting motor 9 drives the adjusting wheel 5 to rotate, which drives the shaker 43 to swing around the axis of the first rotating bearing 8, adjusting the shaker 43 to the tilt angle that matches the current liquid level.

[0047] (3) After adjustment, the magnetic ring 13 is de-energized, the first reset spring 18 pushes the pressing ring 11 to move upward, the pawl 14 re-engages the ratchet, and the tilt angle of the milk shaker 43 is locked.

[0048] (4) Press the first control switch 42 to start the drive motor 37. The drive motor 37 drives the lower frame 26 to revolve via the synchronous belt 40. The shaking rack 43 tilts and revolves with the lower frame 26 at a set angle. The milk produces a rolling motion in the bottle, which promotes the dissolution and uniform mixing of the milk powder. During the shaking process, the shaking rack 43 rotates independently around the mounting base 4 via the first rotary bearing 8. The adjustment mechanism remains stationary, and the wires of the adjustment motor 9 are not twisted.

[0049] The beneficial effects of this embodiment are as follows: By setting a control mechanism linked to the locking mechanism and the adjustment mechanism inside the housing 1, and using a liquid level sensor 17 arranged vertically along the shaking rack 43 to collect the current bottle liquid level information in real time, the control chip 15 automatically drives the adjustment motor 9 to adjust the tilt angle of the shaking rack 43 and triggers the locking mechanism to lock, so that the shaker can adaptively adjust the revolution tilt angle according to different milk volumes without manual setting. When the milk volume is large, the tilt angle is automatically reduced to suppress excessive liquid level rise, and when the milk volume is small, the tilt angle is appropriately increased to enhance the tumbling effect, which helps to improve the ability to remove residual powder at the bottom and powder hanging on the bottle shoulder. It better solves the technical problem that the existing fixed tilt angle scheme is difficult to balance the tumbling strength and liquid level control under different milk volume conditions. The shaking rack 43 and the mounting base 4 are rotatably connected by the first rotary bearing 8, so that... The drive of the adjustment mechanism and the rotation output of the drive component 3 are independent of each other. The adjustment motor 9 is fixed on one side of the mounting base 4 and does not rotate with the milk rack 43. The wire runs on the stationary side, which fundamentally avoids the problem of wire twisting when the motor is arranged on the rotating part. The structure is more reasonable and reliable. The mechanical self-locking structure of the ratchet and pawl 14 does not need to be continuously energized to maintain the lock under normal conditions. The multi-point distributed connection of the fixed mounting structure helps to suppress the eccentric shaking of the mounting base 4 and improve the overall stability of the machine. The upper frame 25 and the lower frame 26 are set separately. The second rotary bearing 33 rolls synchronously with the bottle to release circumferential torque. The two-stage hinge structure of the universal ball head 28 and the waist groove 32 is compatible with the displacement requirements of the support point when the tilt angle changes. The split clamping design of the elastic plate can also adapt to different sizes of milk bottles within a certain range. The overall structure is compact and functionally coordinated, and has good practicality.
