[0035] As shown in Figure 1 and Figure 2 The utility model provides a paddle assembly, which is arranged at the bottom of the milk frother body 100. The paddle assembly comprises a rotating box 1 and a rotating shaft body 2. The rotating box 1 is capable of rotating under the driving of the driving device 200. The rotating box 1 is provided with stirring protrusions 11. The rotating of the rotating box 1 can drive the stirring protrusions 11 to stir the liquid in the milk frother body 100. The rotating shaft body 2 is connected to the rotating box 1 along the height direction of the milk frother body 100. The rotating shaft body 2 is provided with fan blades 21, which are used to stir the liquid in the milk frother body 100.

[0036] Since the rotating box 1 is capable of rotating under the driving of the driving device 200, and the rotating shaft body 2 is provided with fan blades 21, when the rotating box 1 rotates, the rotating shaft body 2 can drive the fan blades 21 to rotate, so as to cut into and stir the liquid in the milk frother body 100. Since the rotating box 1 is provided with stirring protrusions 11, when the rotating box 1 rotates, the stirring protrusions 11 can be driven to stir the liquid in the milk frother body 100. Thus, the "double stirring" structure is formed in cooperation with the fan blades 21, which can generate more intense vortex and shear force. This can not only improve the mixing uniformity of the liquid in the milk frother body 100 and enhance the foaming effect, but also can promote the rapid transmission and distribution of heat at the bottom of the milk frother body 100, so as to effectively avoid the situation that the liquid is scorched due to uneven heating. Specifically, the fan blades 21 are spiral blades commonly used in the field. A plurality of fan blades 21 are uniformly arranged on the rotating shaft body 2.

[0037] Specifically, the milk frother body 100 has a circular truncated cone structure and is used to contain the liquid, such as milk, to be frothed. The rotating box 1 and the rotating shaft body 2 are stacked and arranged at the bottom of the milk frother 100, and the rotating shaft body 2 is fixedly connected to the rotating box 1. Therefore, when the driving device 200 drives the rotating box 1 to rotate, the rotating box 1 will drive the rotating shaft body 2 to rotate, so as to stir the liquid. It can be understood that the paddle assembly can be directly connected to the bottom of the milk frother body 100, or can be hung and arranged at the bottom of the milk frother body 100 through a cup cover or the like. As long as it can stir the liquid at the bottom of the milk frother body 100, the specific connection mode is not limited herein.

[0039] Further, the rotating box 1 and the rotating shaft body 2 are welded, for example, the rotating box 1 and the rotating shaft body 2 can be ultrasonic welded, heat conduction welded or laser welded, etc., and the welding connection improves the connection strength of the rotating box 1 and the rotating shaft body 2 and the sealing performance of the joint. Specifically, the rotating shaft body 2 is a cylindrical structure, and the rotating box 1 has a connecting pipe at the top, the connecting pipe has the same diameter as the rotating shaft body 2, and the two are butted together and then welded.

[0040] Further, as shown in Figure 2 The stirring protrusions 11 have a pushing surface for pushing the liquid, and the pushing surface is perpendicular to the moving direction of the stirring protrusions 11, so as to maximize the conversion of the torsional force of the rotating box 1 into the pushing force on the liquid, thereby causing more intense vortex and shear force of the liquid.

[0041] Specifically, as shown in Figure 2 The stirring protrusions 11 are plate-shaped structures having two opposite and parallel pushing surfaces, and the pushing surfaces extend in the height direction of the milk frother body 100, thereby increasing the contact area with the liquid and improving the stirring effect on the liquid.

[0042] Further, the stirring protrusions 11 are integrally formed with the rotating box 1, which ensures the connection strength of the stirring protrusions 11 and the rotating box 1, so that the paddle assembly can stir the liquid with high viscosity.

Since the rotating shaft body 2 is provided with the fan blades 21, the fan blades 21 can cut into and stir the liquid, thereby frothing the liquid; since the rotating box 1 is also provided with the stirring protrusions 11, the stirring protrusions 11 can rotate to stir the liquid at the bottom of the milk frother body 100, thereby further improving the frothing effect of the milk frother, and also promoting the rapid transmission and distribution of heat at the bottom of the milk frother body 100 and avoiding the situation that the liquid is scorched due to uneven heating, thereby improving the production quality of the milk froth.

[0044] Specifically, as shown in Figure 1As shown, the driving device 200 is provided with a driving magnet 210, the rotating box 1 has a mounting cavity, the mounting cavity is provided with a following magnet 12, and the driving magnet 210 can drive the following magnet 12 to rotate.

It can be understood that the paddle assembly can be directly connected to the bottom of the milk frother body 100, or can be hung on the bottom of the milk frother body 100 through a cup cover or the like, as long as it can realize the stirring of the liquid at the bottom of the milk frother body 100, and the specific connection mode is not limited herein.

[0045] As an example, the milk frother further includes a spoiler 300, the lower end of the milk frother body 100 is provided with a fixed shaft 400, the middle of the rotating shaft body 2 has a shaft hole 22, and the end of the spoiler 300 is arranged in the shaft hole 22 and sleeved on the fixed shaft 400; the spoiler 300 has spoiler blades, and the spoiler 300 remains stationary during the rotation of the paddle assembly, so as to disturb the rotating milk and make the prepared milk foam more delicate and dense; and the rotating box 1 rotates around the end of the spoiler 300 as the shaft.

[0046] Further, as shown in Figure 1 and Figure 2 , the rotating box 1 is provided with a positioning groove 13, the positioning groove 13 is used for clamping with the placing device of the following magnet 12, so as to align the mounting cavity with the following magnet 12; specifically, when assembling the paddle assembly, the rotating box 1 needs to be placed on the placing device of the following magnet 12 and the placing device needs to be clamped with the positioning groove 13, so that the following magnet 12 is aligned with the mounting cavity, thereby ensuring the accuracy of the installation of the following magnet 12.
