While the milk frother heats the milk, since a stirring device is provided in the pot cavity of the milk frother, the stirring device is driven to rotate by a motor, thereby driving the liquid contained in the cup body to rotate, thereby realizing the stirring function. This can not only achieve the purpose of heating the milk, but also make the milk more dense, saving the time of manually making milk foam. However, there is a problem of inaccurate positioning between the existing stirring device and the heating cup, and the stirring device may fall when pouring milk or the stirring device may make too much noise during rotation, which may easily cause damage to the stirring device and affect the user's experience.

[0026] In another embodiment, the shaft head 310 is a streamlined structure that is wide in the middle and narrow at the top and bottom. The shaft head 310 of this structure facilitates the shaft 300 to be accurately inserted into the through hole 110, and also facilitates the shaft 300 to be quickly pulled out of the through hole 110, thereby improving the connection flexibility between the bracket 100 and the shaft 300.

[0027] In another embodiment, the cross-sectional area of ​​the shaft head 310 is larger than the cross-sectional area of ​​the shaft 300. This structure ensures that the shaft 300 is inserted into the through hole 110 and fixed by the shaft head 310, thereby preventing the bracket 100 from falling off during use and improving the stability of the stirring device.

[0028] In another embodiment, a connection portion 140 is provided between the handle 130 and the bracket 100, and a cavity 141 is provided in the connection portion 140 for accommodating the shaft head 310.

[0029] In another embodiment, the bracket 100 is provided with a channel 160 directly opposite to the through hole 110, and the distance between the channel 160 and the connecting portion 140 is greater than the height of the shaft head 310. By providing the channel 160, the contact area between the rotating shaft 300 and the bracket 100 is increased, and the stability of the stirring device is improved.

[0030] In another embodiment, the length of the rotating shaft 300 is equal to the depth of the through hole 110. This structure ensures that the bracket 100 can be stably clamped between the shaft head 310 and the base 320 after the rotating shaft 300 is inserted into the through hole 110, thereby preventing the bracket 100 from loosening during the rotation process and affecting the quiet performance of the stirring device.

[0031] In another embodiment, a fixed coil 210 is further provided between the spring coil 200 and the groove 120. By providing the fixed coil 210, it is ensured that the spring coil 200 can be stably sleeved in the groove 120, and the spring coil 200 is prevented from loosening during the stirring process, which affects the integrity of the stirring device.

[0032] Reference Figure 3 and Figure 4 The embodiment of the utility model further provides a milk frothing machine, including a cup body 400, a driving assembly 500 and the stirring device as described above; the rotating shaft 300 is fixed to the bottom of the cup body 400, and the driving assembly 500 drives the bracket 100 to rotate.

[0033] By providing the bracket 100 and the rotating shaft 300, the bracket 100 can be stably and flexibly fixed in the cup body 400, preventing the bracket 100 from falling off during use, thereby ensuring the working stability of the milk frother; by providing the shaft head 310 and the base 320, the bracket 100 can be accurately clamped between the shaft head 310 and the base 320, and the driving assembly 500 can stably drive the bracket 100 to rotate, preventing the bracket 100 and the spring ring 200 from being displaced during the rotation process, thereby improving the positioning accuracy of the stirring device. At the same time, since the rotating shaft 300 is inserted into the through hole 110 and fixed by the shaft head 310, it is prevented that the bracket 100 falls off the rotating shaft 300 during the inversion of the cup body 400, thereby affecting the integrity and ease of use of the milk frother.

[0034] In another embodiment, a driven magnetic block 150 is provided in the bracket 100, and the driving assembly 500 includes an active magnetic block 510 driving the driven magnetic block 150 to rotate and a motor 520 driving the active magnetic block 510 to rotate. By providing the driven magnetic block 150 and the active magnetic block 510, it is ensured that the motor 520 can stably drive the bracket 100 to rotate, and the stirring device is detachable, thereby improving the convenience of using the milk frother.

[0035] In another embodiment, the base 320 is riveted to the bottom of the cup body 400. This structure ensures the connection stability between the rotating shaft 300 and the cup body 400, avoids the stirring device from loosening during the stirring process, and improves the working stability of the milk frother.

[0036] The working principle of the utility model is further explained below.

[0037] During the production process, firstly, according to the size and specification of the milk frother, the bracket 100, spring coil 200, rotating shaft 300 and cup body 400 of appropriate size are selected, the spring coil 200 and the fixed coil 210 are sleeved in the groove 120, the base 320 is riveted to the bottom of the cup body 400, and then the rotating shaft 300 is inserted into the through hole 110 so that the bracket 100 is clamped between the shaft head 310 and the base 320; the active magnetic block 510, the motor 520 and other components are installed in the cup body 400 in sequence, thus completing the production process of the milk frother.

[0038] During use, pour liquid such as milk into the cup body 400, start the motor 520, and the motor 520 drives the active magnetic block 510 to rotate; the active magnetic block 510 drives the driven magnetic block 150 to rotate, and then drives the bracket 100 to rotate around the through hole 110, and the spring ring 200 stirs the milk to form milk foam. During the stirring process, since the bracket 100 is clamped between the shaft head 310 and the base 320, and since the bracket 100 is provided with a channel 160 that is directly opposite to the through hole 110, the contact area between the rotating shaft 300 and the bracket 100 is increased, so that the bracket 100 can be stably fixed between the shaft head 310 and the base 320 during the rotation process. Since the length of the rotating shaft 300 is equal to the depth of the through hole 110, the bracket 100 can be effectively prevented from jumping up and down during the rotation process, effectively reducing the noise generated during the operation of the milk foam machine, and ensuring the stirring efficiency of the milk foam machine. After the stirring is completed, the motor 520 is stopped. During the process of pouring the milk foam, the cross-sectional area of ​​the shaft head 310 is larger than the cross-sectional area of ​​the rotating shaft 300, so that the bracket 100 is prevented from falling off from the rotating shaft 300. When the bracket 100 needs to be cleaned, the shaft head 310 only needs to be pulled out of the through hole 110 by force, so that the bracket 100 is separated from the cup body 400, and the bracket 100 and the cup body 400 are cleaned separately, thereby ensuring the convenience of maintenance of the milk foam machine.

[0039] From the above description, it can be seen that the stirring device and the milk frother of the present invention are provided with a bracket 100 and a rotating shaft 300, so that the bracket 100 can be stably and flexibly fixed in the cup body 400, thereby preventing the bracket 100 from falling off during use and ensuring the working stability of the milk frother; by providing a shaft head 310 and a base 320, the bracket 100 can be accurately clamped between the shaft head 310 and the base 320, and the driving assembly 500 can stably drive the bracket 100 to rotate, thereby preventing the bracket 100 and the spring coil 200 from being displaced during the rotation process, thereby improving the positioning accuracy of the stirring device; by providing a driven magnetic block 150 and an active magnetic block 510, it is ensured that the motor 520 can stably drive the bracket 100 to rotate, and the detachability of the stirring device is also ensured, thereby improving the convenience of using the milk frother.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
