[0028] The bottom of the milk shaking bracket 3 is connected with a balancing connector 7, and the rotation center line of the balancing connector 7 corresponds to the axis of the rotation center shaft 5. A conducting shaft hole is penetrated on the balancing connector 7 along the axial direction of the rotation center shaft 5 or along the axial direction of the balancing connector 7 (corresponding to the length direction of the rotation center line of the balancing connector 7), and the rotation center shaft 5 is at least partially penetrated through the conducting shaft hole and is clearance-matched with the balancing connector 7.

[0029] The housing is connected with a balancing bearing 6, and the axial direction of the balancing bearing 6 corresponds to the axial direction of the rotating central axis 5. The balancing connector 7 is pressed on the inner ring of the balancing bearing 6 along the axial direction of the rotating central axis 5, and the inner ring of the balancing bearing 6 forms a balancing force exerted on the balancing connector 7 toward the rotating central axis 5. Correspondingly, the balancing connector 7 has a connecting surface 701 that matches the inner side surface of the inner ring of the balancing bearing 6.

[0030] The design is such that the balancing coupling 7 and the balancing bearing 6 are pressed together, and then the balancing bearing 6 is assembled with the outer ring of the housing 1, and then the balancing coupling 7 is assembled with the milk-shaking bracket 3, and then the corresponding shaft is inserted into the inner ring of the balancing bearing 6 to drive the milk-shaking bracket 3; non-contact support rotation is formed between the corresponding shaft and the balancing bearing 6, and the step gap is small and the overall dynamic balance is better through the press-fit connection of the balancing coupling 7.

[0031] Preferably, a shock-absorbing sleeve 13 sleeved on the rotating central axis is provided between the rotating central axis 5 and the milk-shaking bracket 3 .

[0032] In some embodiments, the motor 2 can be a high-torque, low-speed motor without the need for an external gearbox, which effectively reduces the occurrence of abnormal noise and extends the life of the motor relatively well.

[0033] In some embodiments, the balancing bearing 6 can be a bearing made of metal material, and the balancing connecting part 7 is also made of metal material. Through direct mechanical assembly between metals, the step gap of the metal material can be controlled within a certain range, and the dimensional deviation is relatively small, which is more conducive to improving dynamic balance.

[0034] In this embodiment, the balancing connector 7 is cylindrical, and a first connecting column 8 arranged along the axial direction of the balancing connector is connected to the inner wall of the balancing connector 7 . A connecting hole 9 is formed on the first connecting column 8 along its length direction.

The overall installation space is effectively saved. Figure 2 The second connecting post 10 is shown pressed onto the first connecting post 8 .

[0037] Preferably, a wiring space 12 is formed between the portion of the rotating central axis 5 that passes through the conducting shaft hole, the balancing connector 7 and the second connecting column 10. In some embodiments, the wiring space can be used for wiring or setting other temperature sensing devices.

[0038] In some embodiments, the balancing connector 7 can be a machined part of aluminum alloy, for example, an aluminum extruded profile is machined to a corresponding size. The first connecting column 8 can be integrally formed and connected to the balancing connector 7 .

[0039] like Figure 4 , 5 As shown, the number of the first connecting columns is 2, and a corresponding number can be set according to the connection strength design or other needs.

[0040] In this embodiment, an electric heating component corresponding to the breast shaking support 3 is arranged on the housing 1 .

[0041] The electric heating assembly includes a fan 14, an electric heating element 15 and an air duct 16 mounted on the housing 1. The fan 14 blows the air that exchanges heat with the electric heating element 15 to the milk shaking support 3 through the air duct 16. The electric heating element 15 can be a PTC heating element. The air duct 16 can be formed by a tubular member. In some embodiments, the air duct can be formed by a housing.

[0043] Furthermore, a temperature sensor is provided on the air duct 16. The temperature sensor may be an NTC sensor.

[0044] In some embodiments, the control system of the electric milk shaker detects the temperature in the air duct 16 through a temperature sensor, thereby controlling the electric heating element 15 to change the air outlet temperature, thereby indirectly adjusting the heating temperature of the milk bottle on the milk shaking stand 3.

[0045] In some embodiments, the milk shaking stand 3 is in a cylindrical shape with an open top, and the user can place the milk bottle on the internal milk shaking cavity of the cylindrical milk shaking stand through the top opening. The cylindrical milk shaking stand 3 forms an anti-shaking protection for the milk bottle.
