[0004] In the above solution, a motor is used to rotate the milk shaker cup, thereby rotating the milk bottle. Currently, the motors used to shake milk bottles are typically low-torque motors, making them susceptible to significant external influences. During testing, it was found that faster motor speeds caused the entire device to vibrate, and even caused the milk bottle to fly. Summary of the Invention

Every time the milk shaking basket rotates one circle, the magnet on its outer wall will pass through the Hall element once. The Hall element counts the number of rotations of the milk shaking basket and feeds back to the control module. The control module determines whether the speed of the driving motor is increasing, and thus controls the current of the driving motor to keep the speed of the driving motor stable, thereby preventing the bottle from being thrown away.

The upper end of the fixing frame extends into the milk shaking basket and is equipped with a temperature sensor for sensing the temperature of the milk bottle.

[0013] By setting a temperature sensor, the temperature of the heated milk bottle can be controlled, thereby achieving the effect of controlling the temperature of the milk bottle and keeping it warm. The temperature sensor can be any existing temperature detecting sensor.

[0014] Preferably, a vertically extending support rod is provided in the transmission part, a first spring is sleeved on the support rod, the support rod is passed through the fixing frame and the first spring elastically supports the fixing frame, and the fixing frame has a tendency to move upward under the action of the first spring.

[0036] A heat-insulating housing 9 is located within the main housing 1. This housing is positioned within the heating housing 73 and extends toward the auxiliary housing 11. A milk-shaking basket 2 is located within the auxiliary housing 11. This upwardly open basket is used to hold feeding bottles. The walls of the milk-shaking basket 2 are provided with a plurality of through-slots 23 extending from the inside to the outside. These slots 23 communicate with the heating chamber, allowing hot air from the heating chamber to flow into the milk-shaking basket 2. Elastic clips 21, made of deformable plastic, are provided on the inner circumference of the basket 2 to grip the outer wall of the feeding bottle.

[0037] like Figure 2 、 Figure 4 and Figure 5 As shown, a downwardly extending transmission portion 22 is provided at the lower end of the milk shaking basket 2. The transmission portion 22 is integrally formed with the milk shaking basket 2. A bearing 24 is sleeved and fixedly secured to the circumferential outer side of the transmission portion 22. A bearing chamber is provided at the opening of the heat-insulating housing 9. The bearing 24 is secured within the bearing chamber to achieve a rotational connection between the transmission portion 22 and the heat-insulating housing 9. The transmission portion 22 extends downwardly into the heat-insulating housing 9, which is hollow and insulates against hot air.

[0038] The main housing 1 houses a drive motor 4. The insulated housing 9 includes an open accommodating cavity extending downwardly through the heating housing 73. The drive motor 4 is located within the accommodating cavity, and its output shaft 41 extends into the upper side of the insulated housing 9 and is connected to the transmission unit 22 via a linkage 221 to drive the milk shaking basket 2. The linkage 221 has a flat surface milled on its circumferential outer wall and is secured within a groove at the lower end of the transmission unit 22. The linkage 221 also includes a second axially extending through-hole. The output shaft 41 extends into the second through-hole and is secured to the linkage 221 via a key, bolts, and other components.

[0039] like Figure 3 、 Figure 7 and Figure 8As shown, a Hall assembly is provided within the heat-insulating housing 9. The Hall assembly includes a Hall element 91 and a magnet (not shown). A downwardly opening fixing slot 92 is provided on the lower outer wall of the transmission portion 22. The magnet is fixedly mounted within the fixing slot 92. The Hall element 91 is fixed to the heat-insulating housing 9 below the transmission portion 22. When the transmission portion 22 rotates, the magnet rotates and passes through the Hall element 91, which then counts. A control module 8 is provided within the main housing 1. The control module 8 is located outside the heating housing 73. The control module 8 is a main circuit board that controls the operation of the drive motor 4 and the heating module 7. The Hall element 91 is electrically connected to the control module 8 via a wire (not shown) and transmits electrical signals to the control module 8.

The two support columns 25 are jointly provided with a fixing frame 5, and the fixing frame 5 is supported on the first spring 251. The first spring 251 applies an upward force to the fixing frame 5. The upper end of the fixing frame 5 extends into the milk shaking basket 2 and is equipped with a temperature sensor 6. The temperature sensor 6 is an NTC temperature sensor. The temperature sensor 6 is used to contact the milk bottle above and sense the temperature of the milk bottle.

[0041] The NTC temperature sensor has a first pin 61 and a second pin 62. The first pin 61 is connected to the wall of the transmission unit 22 via a conductive sheet 64. The transmission unit 22 is made of conductive material and transmits electrical signals through the bearing 24. The outer ring of the bearing 24 is connected to the control module 8 via a first wire (not shown). The second pin 62 is connected to a screw 63, which extends downward into the second through-hole. The output shaft 41 and the screw 63 are connected via a second spring 222. The housing of the drive motor 4 is made of conductive material and is connected to the control module 8 via a second wire (not shown). The control module 8 uses the signal from the NTC temperature sensor to control the heating of the heating module 7.

[0042] During use, the user places a feeding bottle in the milk shaking basket 2, allowing the elastic clip 21 to clamp the bottle. The drive motor 4 then rotates the milk shaking basket 2, causing the bottle to spin. During this rotation, the Hall effect sensor counts the number of times the milk shaking basket 2 rotates and sends a signal to the control module 8. When the control module detects an increase in the speed of the milk shaking basket 2, it controls the current flowing to the drive motor 4, thereby controlling the rotation speed of the drive motor 4. Simultaneously, the temperature sensor 6 senses the temperature of the milk bottle and transmits a signal to the control module 8, which controls the operation of the heating module 7 to achieve the desired heating or heat preservation effect.
