Mute stirrer for milk foam machine

Abstract

The utility model discloses a mute stirrer for a milk foam machine, which comprises an upper cover, a lower cover, a fixed shaft and a ball body, the upper cover extends upwards to form a long groove for the fixed shaft to enter, and the ball body is positioned in the long groove and is respectively abutted against the fixed shaft and the inner wall of the long groove. According to the utility model, when the stirrer is driven to rotate through the rotation of the external motor and magnetic force, the ball body is in point contact with the fixed shaft, so that the generated noise is very low, and the practicability is very high.

Description

Technical Field

[0001] The utility model relates to the technical field of milk frothers, in particular to a silent stirrer for a milk frother. Background Art

[0002] In the stirring device of the existing milk frother, a metal cap is arranged between the upper cover and the lower cover. The metal cap is integrated with the upper cover and is used in cooperation with a magnet on the stirring device through an external motor. The magnetic force drives the stirring device to rotate, thereby driving the metal cap to rotate. The disadvantage of this technical solution is that the contact area between the metal cap and the fixed shaft is large, resulting in a large amount of noise. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a silent stirrer for a milk frother.

[0004] To solve the above problems, the utility model adopts the following technical solutions.

[0005] A silent stirrer for a milk frother, including an upper cover, a lower cover and a fixed shaft, further including a sphere. The upper cover extends upward with a long groove for the fixed shaft to enter. The sphere is located in the long groove and the sphere abuts against the fixed shaft and the inner wall of the long groove respectively.

[0006] As a further improvement of the utility model, the sphere is in interference fit with the long groove.

[0007] Advantages of the Utility Model

[0008] Compared with the prior art, the advantages of the utility model are as follows:

[0009] When the stirrer is rotated by the magnetic force driven by the rotation of the external motor in the utility model, the sphere contacts the fixed shaft at a point, so the generated noise is very small and it has high practicability. Description of the Drawings

[0010] Figure 1 It is a cross-sectional view of the utility model.

[0011] Figure 2 It is a schematic diagram of the structural disassembly of the utility model. Detailed Embodiments

[0012] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0013] Please refer to Figures 1 to 2 , a silent stirrer for a milk frother, comprising an upper cover 1, a lower cover 2 and a fixed shaft 3, further comprising a sphere 4. The upper cover 1 extends upward with a long groove 11 for the fixed shaft 3 to enter. The sphere 4 is located in the long groove 11 and the sphere 4 is in contact with the fixed shaft 3 and the inner wall of the long groove 11 respectively. When the external motor rotates and the magnetic force drives the sphere 4 to rotate, the sphere 4 contacts the fixed shaft 3 at a point, so the generated noise is very small and it has high practicability. It should be noted that the structure between the upper cover and the lower cover is the same as that of the prior art, and the magnet is located in

[0014] Preferably, the sphere 4 is in interference fit with the long groove 11, which has a simpler assembly structure, higher assembly efficiency and lower production cost compared with the prior art.

[0015] Preferably, the sphere 4 is made of a ceramic sphere, which can further improve the wear resistance of the sphere 4 and has a longer service life.

[0016] Summary: In the old structure, the fixed shaft 3 rubs against the metal cap, wears quickly and has a short service life. In the new structure, the fixed shaft 3 rubs against the ceramic ball, and the ceramic ball is made of wear-resistant zirconia ceramic with good wear resistance, small wear and greatly improved service life.

[0017] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improved concept of the present invention, makes an equivalent substitution or change, and should be covered by the protection scope of the present invention.
