[0029] The contents of this disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1 to 5 As shown, this disclosure provides a rotor mechanism for a milk frother, including a rotor structure 10, a filter structure 20, and a flow-blocking frame 30. The rotor structure 10 has a shaft portion 11, and the filter structure 20 is detachably connected to the shaft portion 11. The flow-blocking frame 30 includes a central impeller frame 31 and a plurality of support columns 32 arranged around the outer periphery of the central impeller frame 31. The central impeller frame 31 and the plurality of support columns 32 form a cage-like receiving space 33. The filter structure 20 is at least partially located within the cage-like receiving space 33, and the support columns 32 are located on the outer periphery of the filter structure 20. The rotation of the rotor structure 10 causes the milk to generate a vortex, and the flow-blocking frame 30 can press the vortex generated by the rotation of the milk down onto the filter structure 20.

[0031] Reference Figures 1 to 3 For example, the rotor structure 10 has a shaft portion 11 at its top, and the filter structure 20 is detachably connected to the shaft portion 11, at least partially covering the outer peripheral surface of the shaft portion 11. This arrangement allows the filter structure 20 to be easily disassembled, cleaned, or replaced by the user after a period of use, ensuring the cleanliness and performance of the filter structure 20, thereby ensuring the quality of the milk foam. The detachable connection between the filter structure 20 and the shaft portion 11 can be a snap-fit ​​connection, a threaded connection, or other suitable connection method. The appropriate method can be selected based on actual usage requirements and manufacturing processes.

[0032] Reference Figure 2As shown, exemplarily, several support pillars 32 are evenly spaced along the circumference of the central impeller frame 31. The number of support pillars 32 can be three or more. The inner diameter of the cage-like receiving space 33 is larger than the outer diameter of the filter structure 20. This provides a reasonable receiving space for the filter structure 20 and facilitates the flow and processing of milk driven by the rotation of the rotor structure.

[0033] Specifically, during operation, the rotation of the rotor structure 10 causes the milk to swirl, and the flow-blocking frame 30 presses the swirl generated by the rotating milk down onto the filter structure 20. The rotational motion of the rotor structure 10 drives the milk to flow inside the milk frother, forming a vortex. The flow-blocking frame 30, through its structural design, presses the vortex down onto the filter structure 20. The filter structure further processes the milk, allowing the air in the milk to mix thoroughly with the milk, thereby producing a finer and more uniform milk foam.

[0034] In related technologies, a rotor with an integrated impeller structure is used to achieve latte art effects. However, this method can only process a fixed amount of milk foam, and it is often unsuitable when customers require more or less milk foam. The milk foam produced by related technologies is too thick and cannot be used for latte art. In addition, due to the complexity of the integrated impeller structure, it is difficult to clean after use. The embodiment of this disclosure uses the rotation of the rotor structure 10 to create a vortex in the milk inside the container. The flow-blocking frame 30 inside the container can press the vortex generated by the rotation of the milk onto the filter structure 20 and mix it evenly, so that the milk foam and milk are fully integrated. The milk foam has good fluidity and is delicate, which can meet the requirements of latte art.

[0035] The rotor mechanism of the milk frother in this embodiment generates a vortex in the milk by rotating the rotor structure 10. The vortex is then pressed down onto the filter structure 20 by the flow-blocking frame 30, which enables the air in the milk to be fully mixed with the milk, effectively improving the fineness and uniformity of the milk foam, meeting the user's demand for high-quality milk foam. The milk foam has good fluidity and is fine, which can meet the requirements for latte art.

[0036] In this embodiment of the milk frother rotor mechanism, the filter structure 20 and the shaft 11 are detachably connected, facilitating user disassembly, cleaning, or replacement of the filter structure 20. This ensures the cleanliness and performance of the filter structure 20 and extends the service life of the milk frother rotor mechanism. The rotor structure 10, filter structure 20, and flow-blocking frame 30 work together to improve the fineness and uniformity of the milk foam.

[0037] Reference Figure 1 As shown, in one embodiment, the shaft portion 11 adopts a cylindrical structure. The filter structure 20 is connected to the shaft portion 11 by a snap-fit ​​connection.

[0038] Reference Figure 1 As shown, the central impeller frame 31 is a circular plate-shaped structure. Three support pillars are evenly arranged around the outer periphery of the central impeller frame 31. One end of each support pillar 32 is fixedly connected to the central impeller frame 31, and the other end extends downward. The diameter of the filter structure is slightly smaller than the inner diameter of the cage-like receiving space, allowing the filter structure 20 to be smoothly placed into the cage-like receiving space.
