DETAILED DESCRIPTION

[0033] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0034] Embodiment 1

[0035] Please refer to Figures 1-7 As shown in the drawings, the present application provides an eccentric milk shaker, which comprises a base 1 and a milk bottle container 2 arranged on the base 1, the milk bottle container 2 is used for placing and limiting a milk bottle 3, a drive assembly 4 is installed on the base 1, and an eccentric part 6 for lifting the milk bottle is installed on the drive shaft 5 of the drive assembly 4, wherein the eccentric part 6 comprises an eccentric shaft 6a which is not coaxial with the drive shaft 5.

[0036] The present application newly designs a milk shaker which works in the mode of driving the eccentric shaft based on the drive assembly. This product abandons the previous method of directly driving the milk bottle at high speed, and instead uses a more moderate eccentric shaft linkage mode. After starting the drive assembly 4, the drive assembly 4 rotates to drive the non-coaxial eccentric shaft 6a to make periodic slow circular movement, and in turn drives the milk bottle 3 lifted by the eccentric part 6 to oscillate in a predetermined track within a small range without spinning. On the premise of ensuring sufficient shaking force for the milk bottle 3, the excessive violent shaking effect is avoided, the risk of the milk bottle 3 falling out of the milk bottle container 2 is reduced, the production amount of air bubbles in the milk liquid is effectively reduced, the noise intensity generated during operation is greatly weakened, and a quiet and comfortable nursing environment is created. In the present embodiment, the drive assembly 4 is preferably a motor, and the drive shaft 5 is a motor shaft. It is easy to know that, in order to optimize the transmission effect, the drive assembly 4 can also be connected to the eccentric part 6 through other transmission modes such as gear rack or belt transmission.

[0037] Further, in the embodiment, the eccentric member 6 further comprises a cam 6b, and the eccentric shaft 6a and the cam 6b are oppositely located on both sides of the drive shaft 5. When only a single eccentric shaft 6a is designed, the load center of gravity on the drive shaft 5 is offset to one side, resulting in unbalanced force on the shaft, and the milk bottle container 2 and the milk bottle 3 on the drive shaft 5 shake obviously during the operation of the machine, and the noise increases. By optimizing the design of the eccentric member structure, the cam 6b and the eccentric shaft 6a are oppositely arranged, the center of gravity of the eccentric part on the drive shaft 5 is balanced, the center of gravity of the system can be adjusted by the action of gravity, and during the operation of the machine under load, the system has a certain dynamic balance calibration function, which can reduce the shaking of the milk bottle 3 on the upper part of the machine, weaken the vibration of the shell of the base 1, and help to eliminate potential imbalance during the operation of the machine.

[0038] As an example of one of the designs, the milk bottle container 2 has a bottom plate 7, and the eccentric member 6 is connected with the bottom plate 7 through a first bearing 8. The inner ring of the bearing rotates with the eccentric member 6 around the drive shaft 5, and the outer ring of the bearing is fixed on the bottom plate 7 of the milk bottle container 2. During the operation of the drive assembly, the milk bottle container 2 moves in a circular trajectory around the drive shaft 5 as the center, and the container itself does not rotate, which can reduce the shaking of the machine.

[0039] As an optimized design, the bottom plate 7 is connected with the base 1 through a first elastic member 9. The first elastic member 9 can be made of silica gel or rubber, has good buffering and elastic properties, and can effectively absorb vibration energy.

[0040] Further, the bottom of the bottom plate 7 is provided with a boss 10, the bottom of the boss 10 is provided with a first recess 11, and the first bearing 8 is installed in the first recess 11. The first elastic member 9 is annular, the inner ring of the first elastic member 9 is fixed on the outer side of the boss 10, the outer edge of the first elastic member 9 is fixed on the base 1, and the middle part of the first elastic member 9 can be a wave-shaped elastic body.

[0041] The design form of the first elastic member 9 is not limited to the annular structure described above. In other implementations, the first elastic member 9 can also be one or more rocker arms 9a. One end of the rocker arm 9a is fixed on the bottom plate 7, and the other end of the rocker arm 9a is fixed on the base 1, which is used to buffer the vibration to a certain extent. As an optimization, the inner side of the plurality of rocker arms 9a can be fixed on the bottom plate 7 through an entire inner ring member 9b, and the outer side of the plurality of rocker arms 9a can be fixed on the base 1 through an entire outer ring member 9c, which can improve the connection stability.

[0042] According to one example of this utility model, a clamping member 12 is detachably installed at the top of the baby bottle container 2. The clamping member 12 has a clamping opening 13 in the middle for the baby bottle to enter. After the baby bottle 3 is inserted into the baby bottle container 2 through the clamping opening 13, the clamping member 12 holds the upper middle part of the baby bottle 3, constraining and restricting the baby bottle 3 so that it is not easy to fall out. Specifically, the clamping member 12 is a flexible sleeve, which can be made of silicone or rubber, and provides flexible and elastic clamping to the outer wall of the baby bottle 3. The inner edge of the flexible sleeve located at the clamping opening 13 is provided with multiple expansion joints 14 to adapt to the insertion of baby bottles 3 of different diameters.

[0043] Example 2

[0044] This embodiment, based on the above embodiments, provides a second design example of an eccentric milk shaker structure, such as... Figures 8-11 As shown, in this design, the bottle container 2 is fixed on the base 1, and the eccentric component 6 is connected to the second elastic component 16 via the second bearing 15. The bottom of the bottle 3 is positioned above the second elastic component 16, and the second elastic component 16 is connected to the base 1. This design eliminates the shaking of the bottle container 2 in traditional structures. The bottle container 2 only serves to contain and limit the bottle 3. The bottle 3 is supported and driven by the eccentric component 6 and the second elastic component 16 at the bottom, which further reduces machine shaking.

[0045] Furthermore, the second elastic member 16 has a platform 17 for supporting the bottle in the middle. The bottom of the bottle 3 is placed directly on the platform 17 and shakes accordingly. The bottom of the platform 17 has a second groove 18 for installing bearings and eccentric parts. The second bearing 15 is installed in the second groove 18. In this embodiment, the second elastic member 16 is generally disc-shaped. The outer ring 16a of the second elastic member 16 is fixed on the base 1. The middle part of the second elastic member 16 can be an elastic body that is bent multiple times in a wave-like shape.

[0046] Example 3

[0047] This embodiment, based on Embodiment 1 above, provides a third design example of an eccentric milk shaker structure, such as... Figures 12-13 As shown, the axis of the eccentric component 6 forms an angle with the axis of the drive shaft 5, so that while the bottle container 2 moves in a circular trajectory around the drive shaft 5 as the central axis, it also has a vertical trajectory movement. Compared with the shaker design in the previous embodiment, the shaking trajectory of the eccentric shaker in this embodiment is more three-dimensional, and the milk powder is shaken better.
