The external air is heated when passing through the heater 62, so that the air entering the placement basket 3 through the multiple air holes 32 is hot air, so as to heat multiple positions of the milk bottles placed in the placement basket 3, so that the milk in the milk bottles is heated evenly.

[0033] like Figure 4 As shown, in some preferred embodiments, a fixing sleeve 8 is provided in the housing 1, a moving rod 9 is provided in the fixing sleeve 8, the moving rod 9 is connected to a spring 10, one end of the moving rod 9 passes through the fixing sleeve 8, the mounting plate 2 and the through hole 31 in sequence and extends into the placement basket 3, and one end of the first probe 5 connected to the wire is inserted into one end of the moving rod 9. In practical applications, the bottom of the milk bottle is flat or concave. By arranging the first probe 5 on the moving rod 9 and connecting the moving rod 9 to the spring 10, when the milk bottle is placed in the placement basket 3, the moving rod 9 can always keep in contact with the bottom of the milk bottle under the elastic force of the spring 10, thereby realizing accurate temperature measurement of milk bottles with different bottom shapes.

Specifically, the rotation drive assembly 12 can be a motor.

[0037] like Figure 6 as well as Figure 7 As shown, in some preferred embodiments, the above-mentioned rotation drive assembly 12 includes a driving motor 121, a driving wheel 122, a driven wheel 123 and a transmission belt 124. The driving motor 121 is arranged on the mounting plate 2. The driving wheel 122 is connected to the output shaft of the driving motor 121. The driven wheel 123 is rotatably arranged on the fixed sleeve 8 and connected to the connecting portion 33. The transmission belt 124 is wound around the driving wheel 122 and the driven wheel 123. In specific applications, the driving motor 121 generates a driving force to drive the driving wheel 122 to rotate, and the driving wheel 122 drives the driven wheel 123 to rotate through the transmission belt 124, thereby driving the placement basket 3 connected to the driven wheel 123 to rotate, and realizing the milk shaking action. The use of this transmission method can avoid the problem of motor blocking and burning during the milk shaking process.

[0038] like Figure 3 and Figure 7As shown, in some preferred embodiments, the upper surface of the driven wheel 123 is connected to the turntable 13, the upper surface of the turntable 13 is provided with a connecting ring 131, the outer side wall of the connecting ring 131 is provided with a connecting key 132, the shape of the connecting portion 33 is a ring adapted to the shape of the connecting ring 131, the side wall of the connecting portion 33 is provided with an opening 331, the connecting ring 131 is located in the connecting portion 33, and the connecting key 132 is located in the opening 331. In specific applications, the connecting ring 131 cooperates with the connecting portion 33 to ensure that the placement basket 3 and the turntable 13 are coaxial after assembly, thereby ensuring the rotation accuracy of the placement basket 3. The connection key 132 cooperates with the opening 331 to ensure that when the turntable 13 rotates, the placement basket 3 rotates synchronously.

[0039] like Figure 7 As shown, in some preferred embodiments, the upper surface edge of the rotating disk 13 is provided with an upwardly bent flange 133, the lower surface edge of the through hole 21 is provided with a downwardly bent flange 211, the flange 211 is located inside the flange 133, a sealing ring 14 is provided between the flange 211 and the flange 133, and the inner side wall and outer side wall of the sealing ring 14 respectively abut against the outer side wall of the flange 211 and the inner side wall of the flange 133. Through the above technical solution, the placement basket 3 can be ensured to rotate smoothly and avoid swinging.

[0040] like Figure 2 and Figure 8 As shown, in some preferred embodiments, the mounting plate 2 is provided with a baffle 22 protruding upward, the baffle 22 surrounds the placement basket 3, and is detachably connected to the air duct 4. In specific applications, by providing the baffle 22 on the mounting plate 2, it is not only convenient to install the air duct 4 on the mounting plate 2, but also can prevent the wind in the air duct 4 from escaping from the gap between the mounting plate 2 and the air duct 4 to affect the heating effect. Specifically, a bayonet is provided on the baffle 22, and a buckle is provided on the air duct 4, and the buckle is clamped in the bayonet.

[0041] like Figure 2 and Figure 8 As shown, in some preferred embodiments, the mounting plate 2 is provided with a sinking area 23, and the bottom of the placement basket 3 is located in the sinking area 23. In specific applications, by providing the sinking area 23 on the mounting plate 2 and making the bottom of the placement basket 3 located in the sinking area 23, not only can the length of the placement basket 3 protruding from the housing 1 be reduced, but also the placement basket 3 is brought closer to the driven wheel 123, so that the placement basket 3 can rotate more stably.

[0042] like Figure 1 and Figure 2As shown, in some preferred embodiments, the above-mentioned milk shaker also includes a lighting assembly 15. The lighting assembly 15 includes a support frame 151, a light source, a transparent lampshade 152 and a vibration sensor. The support frame 151 is arranged on the housing 1.

The vibration sensor (not shown in the figure) is arranged on the control circuit board of the milk shaker and is electrically connected to the light source. In specific applications, the on and off of the light source can be controlled by tapping the milk shaker. For example, when the milk shaker is used at night, the milk shaker is tapped, and the vibration sensor will feed back the sensed vibration to the control circuit board, and the control circuit board controls the light source to be powered on and emit light, and the light emitted by the light source is emitted through the transparent lampshade 152 to achieve night lighting. After use, the milk shaker can be tapped again to turn off the light source. Of course, the light source can also be turned off automatically after it is started for a predetermined time. Specifically, the light source can be a light strip or a light board.

[0043] In specific applications, the above-mentioned first probe 5, heating component 6, second probe 11, rotation drive component 12 and lighting component 15 are all electrically connected to the control circuit board of the milk warmer. The control circuit board is arranged in the shell 1. The control circuit board can receive feedback from the first probe 5 and the second probe 11, and control the heating component 6, the rotation drive component 12 and the lighting component 15 to perform corresponding actions.
