[0005] The connecting piece comprises a central portion and an annular portion, the other end of the connecting shaft is welded to the center of the central portion, and the spring is sleeved on the annular portion.

[0006] A gap is formed between the central portion and the annular portion, the central portion and the annular portion are connected via a connecting portion, an opening is provided on a side of the annular portion opposite to the connecting portion, and the spring is inserted into the annular portion from the opening.

[0007] The spring is an annular spring.

[0008] A center hole is provided at the center of the center portion, and the other end of the connecting shaft is inserted into the center hole and welded.

[0009] The peripheral wall of the other end of the connector is provided with a plurality of convex strips, and the connecting sleeve is sleeved on the convex strips.

[0010] The connecting sleeve is tightly fitted and fixed to the connecting head.

[0011] The other end of the connector is provided with a second connecting hole for inserting the motor shaft.

[0012] The second connecting hole is interference fit with the motor shaft.

[0013] A milk frother comprises the frother described in any one of the above items.

[0014] The connecting head, the connecting shaft, the connecting sleeve and the connecting sheet are all made of metal materials.

[0015] Such a design has the following advantages: in the utility model, after the connecting head and the connecting shaft are integrally formed, the connecting sleeve is pressed into the connecting head, the connecting piece is welded on the connecting shaft, and then the spring is installed, and the several parts are fastened together to form the frothing device. The handheld milk frother equipped with the frothing device can adapt to different speeds and work stably, solving the problem of eccentric vibration caused by the rotation of the frothing device when the handheld milk frother is working, and can maintain balance during work regardless of high or low speed, meeting normal working requirements and ensuring user experience.

[0020] The content of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figures 1 to 2 As shown, this embodiment provides a bubble stirrer, including a connecting head 1, a connecting shaft 3, a connecting sleeve 2, a connecting piece 4 and a spring 5, one end of the connecting head 1 is provided with a first connecting hole, one end of the connecting shaft 3 is inserted into the first connecting hole and the connecting head 1 is formed integrally, the connecting sleeve 2 is tightly sleeved on the peripheral wall of the connecting head 1, the other end of the connecting shaft 3 is welded to the center of the connecting piece 4, and the spring 5 is sleeved on the connecting piece 4.

[0022] In this embodiment, after the connector 1 and the connecting shaft 3 are integrally formed, the connecting sleeve 2 is pressed into the connector 1, the connecting piece 4 is welded to the connecting shaft 3, and then the spring 5 is installed, and the several parts are fastened together to form the frothing device. The handheld milk frother equipped with the frothing device can adapt to different speeds and work stably, solving the problem of eccentric vibration caused by the rotation of the frothing device when the handheld milk frother is working, and can maintain balance during work regardless of high or low speed, meeting normal working requirements and ensuring user experience.

[0023] The connecting piece 4 includes a central portion 41 and an annular portion 42. The other end of the connecting shaft 3 is welded to the center of the central portion 41, and the spring 5 is sleeved on the annular portion 42. A central hole is provided at the center of the central portion 41, and the other end of the connecting shaft 3 is inserted into the central hole and welded. This is conducive to ensuring the concentricity of the spring 5 and the connecting shaft 3, and solving the problem of unbalanced operation caused by non-concentric vibration when the bubble stirrer rotates.

[0024] A gap is formed between the central portion 41 and the annular portion 42, and the central portion 41 and the annular portion 42 are connected via a connecting portion 43. An opening is provided on a side of the annular portion 42 opposite to the connecting portion 43, and the spring 5 is an annular spring 5, which is inserted into the annular portion 42 from the opening.
