[0038] As Figures 1-4The utility model provides a turbulence vane connecting structure for preventing relative rotation between the turbulence vane assembly 2 and the rotating shaft 1. The turbulence vane connecting structure comprises the rotating shaft 1, the turbulence vane assembly 2 and the main blade 3. The rotating shaft 1 extends along the vertical direction and is fixedly arranged in the cup body. The turbulence vane assembly 2 comprises the turbulence vane body 21 and the turbulence vane lower cover 22. The turbulence vane lower cover 22 is connected to the bottom end of the turbulence vane body 21. The turbulence vane lower cover 22 is provided with the mounting groove 220. The rotating shaft 1 is provided with the prismatic mounting portion 11. The mounting portion 11 can extend into the mounting groove 220 and fit the inner wall of the mounting groove 220. The main blade 3 is rotatably sleeved on the outer circumferential side of the rotating shaft 1. When the main blade 3 rotates around the rotating shaft 1, the liquid in the cup body can be stirred.

[0039] The turbulence vane lower cover 22 and the mounting portion 11 cooperate with each other. The mounting portion 11 and the mounting groove 220 capable of fitting the mounting portion 11 are arranged on the turbulence vane lower cover 22. The contact area of the turbulence vane lower cover 22 and the rotating shaft 1 is increased, and the connecting strength between the two is improved. The rotating shaft 1 is fixedly arranged in the cup body, so that the turbulence vane body 21 cannot rotate in the cup body. The liquid in the cup body is driven to flow by the main blade 3 capable of relative rotation. The flowing liquid rotates relative to the turbulence vane body 21. The effect of enhancing liquid mixing and shearing is also achieved. The formation and refinement of foam are promoted, and the safety is higher. Specifically, it can be understood that the shape of the opening of the mounting groove 220 includes but is not limited to a character type, a hexagon and a triangle. Exemplarily, in the embodiment, the shape of the opening of the mounting groove 220 is a character type. Correspondingly, the mounting portion 11 is a rectangular square column, so that the mounting portion 11 can fit the inner wall of the mounting groove 220. In other embodiments, when the shape of the opening of the mounting groove 220 is a hexagon, the mounting portion 11 is adjusted to be a hexagonal prism. When the shape of the opening of the mounting groove 220 is a triangle, the mounting portion 11 is adjusted to be a triangular prism.

[0040] Optionally, in the embodiment, the edges and corners of the mounting portion 11 can be rounded to prevent the user from cutting the hand when disassembling.

[0041] Specifically, the turbulence vane body 21 comprises the connecting sleeve rod 211 and a plurality of turbulence vanes 212. The connecting sleeve rod 211 is provided with an opening at the bottom end. The turbulence vane lower cover 22 is inserted into the connecting sleeve rod 211 through the opening. The plurality of turbulence vanes 212 are arranged at intervals along the circumference of the connecting sleeve rod 211. The turbulence vanes 212 are fixedly connected to the connecting sleeve rod 211. The above-mentioned arrangement can realize the detachable connection between the turbulence vane body 21 and the turbulence vane lower cover 22, and is convenient for disassembly.

[0042] Exemplarily, in the embodiment, the turbulence vanes 212 are centrally symmetrically distributed about the connecting sleeve rod 211, so that the liquid foaming is more uniform, and the stress on the connecting sleeve rod 211 is more balanced.

[0043] Preferably, in the present embodiment, the material of the spoiler under cover 22 is plastic. The above arrangement improves the connection strength between the spoiler under cover 22 and the bottom end opening of the connecting sleeve rod 211 by virtue of the elasticity of the spoiler under cover 22.

[0044] It can be understood that the above-mentioned plastic material is a food-grade plastic material commonly used in the art, and its specific components are not described here.

[0045] More specifically, the side wall of the mounting groove 220 is provided with an avoiding groove 222 extending in the horizontal direction. The above arrangement can provide a part of the deformation stroke when the opening of the mounting groove 220 is deformed under force, preventing irregular deformation of the side wall of the mounting groove 220, which causes the mounting portion 11 to be unable to extend into the mounting groove 220.

[0046] Alternatively, in the present embodiment, the end of the spoiler under cover 22 towards the connecting sleeve rod 211 is provided with a connecting boss, which can extend into the connecting sleeve rod 211, thereby increasing the contact area between the spoiler under cover 22 and the connecting sleeve rod 211 and improving the connection strength therebetween.

[0047] Specifically, the main blade 3 is provided with an adapter groove 310 and an adapter channel extending in the vertical direction, and the adapter channel is connected to the groove bottom of the adapter groove 310. When the shaft 1 extends into the adapter channel, the spoiler under cover 22 extends into the adapter groove 310. The above arrangement of the adapter groove 310 can improve the stability of the spoiler under cover 22 during rotation of the main blade 3.

[0048] More specifically, the outer circumferential side of the shaft 1 is provided with a limiting boss 12, and when the shaft 1 extends into the adapter channel, the spoiler under cover 22 is limited above the limiting boss 12. The above arrangement of the limiting boss 12 can prevent the shaft 1 from moving upward relative to the main blade 3 under liquid pressure, thereby improving the stability of the shaft 1.

[0049] More specifically, the bottom end of the spoiler under cover 22 is provided with a thickened portion 221, which can extend into the adapter groove 310. The above arrangement of the thickened portion 221 lowers the overall center of gravity of the spoiler under cover 22, further improving the stability of the spoiler body 21.

[0050] Specifically, the bottom of the main blade 3 is provided with a blade under cover 31, and the blade under cover 31 is provided with an adapter hole. The outer circumferential side of the shaft 1 is provided with a pressing slope 13, and when the shaft 1 passes through the adapter hole, the inner wall of the adapter hole presses against the pressing slope 13. The above arrangement can increase the contact area between the blade under cover 31 and the shaft 1, thereby improving the stability of the shaft 1.

[0051] The utility model also provides a kind of milk frother, for making milk froth, including cup body, above-mentioned turbulence vane connecting structure and driving mechanism.

[0052] It can be understood that the milk frother has all the beneficial effects possessed by the turbulence vane connecting structure described above, which will not be repeated here.

[0053] It should be noted that the driving mechanism is a motor disclosed in the art, and its specific structure and principle will not be repeated here.

[0054] It can be understood that the cup body, turbulence vane body 21, main paddle 3 and shaft 1 are all food-grade stainless steel materials commonly used in the art, or other food-grade materials, and their specific components will not be repeated here.

[0055] Obviously, the above embodiments of the utility model are only examples for clear illustration of the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description.
