When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only."

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1 to 2 As shown, a milk foam machine stirring rod is characterized by comprising:

[0027] The main body 1 is provided with a control device.

[0028] The stirring device 2 includes a stirring head 21 and a connecting rod 22. The stirring head 21 is arranged on the lower side of the main body 1 through the connecting rod 22.

[0029] The heating device includes an annular heating tube 31 , which is sleeved on the outside of the connecting rod 22 . The lower side of the annular heating tube 31 near the stirring head 21 generates heat.

[0030] The annular heating tube 31 is arranged at the lower side of the main body 1, and only the bottom position generates heat. In this way, the heat source does not directly contact the main body 1, thereby avoiding a large amount of heat transfer to the main body 1, thereby ensuring the service life of the main body 1. At the same time, the bottom position of the annular heating tube 31 generates heat. During the heating process of a small amount of liquid, the upper end position of the annular heating tube 31 can be avoided from dry burning, thereby avoiding the problem of high temperature burns and component damage caused by dry burning.

[0031] In this embodiment, the annular heating tube 31 is a ceramic heating tube, and the heating wire provided on the ceramic heating tube is located at the lower side of the annular heating tube 31. A ceramic heating tube, specifically an MCH ceramic heating tube, is used. At this time, the heating wire of the ceramic heating tube is set at the lower side, so that when the ceramic heating tube is powered on, only the lower side is heated, and the upper end of the annular heating tube 31 does not generate heat. Therefore, during use, the heat on the upper side of the annular heating tube 31 is mainly transferred from the lower side, and the heat transferred to the main body 1 is even less, and the main body 1 is less affected by external heat sources, thereby ensuring the normal use of the main body 1 and the components inside the main body 1, while extending the service life and simplifying the structure of the main body 1. There is no need to set up a related structure to block heat transfer.

[0032] The main body 1 is primarily used to house some control structures, such as buttons, and a motor for securing the stirring device 2. Specifically, in this embodiment, the main body 1 includes a housing 11, which is disposed outside the control device, and the heating device is disposed below the housing 11. The housing 11 is disposed on the outside, the control device and the motor are disposed inside the housing 11, and the stirring device 2 and the heating device, which are connected to the motor, are disposed below the housing 11. Thus, during use, a user can hold the housing 11 by hand and place the stirring device 2 and the heating device into the desired cup.

[0033] At this time, since the heating device is a heat source, in order to ensure the safety of the product during use, in one embodiment, a protective net 4 is provided on the outside of the heating device. The protective net 4 is detachably arranged at the lower side of the shell 11. An L-shaped slot 41 is provided on the top of the protective net 4. The L-shaped slot 41 extends to the top of the protective net 4. A connecting column 111 is provided on the outside of the shell 11. The protective net 4 is fixed to the connecting column 111 of the shell 11 through the L-shaped slot 41. A certain distance is provided between the protective net 4 and the heating device. At this time, the protective net 4 is in a barrel-shaped shape with an opening at the top. The opening at the top is connected to the lower side of the shell 11 through the L-shaped slot 41. At this time, the protective net 4 can be detachably fixed to the lower side of the shell 11 through the structure of the L-shaped slot 41 and the connecting column 111, thereby facilitating subsequent cleaning needs.

[0034] Since the protective net 4 wraps the stirring device 2, and the liquid needs to be driven by the rotation of the stirring device 2, in one embodiment, the protective net 4 is provided with a plurality of arranged hole structures 42, and the hole structures 42 are distributed on the side and bottom of the protective net 4; at this time, the protective net 4 is a plurality of arranged hole structures 42, which can allow the liquid to flow between the inside and outside of the protective net 4, so that when the stirring device 2 rotates, it can drive the flow of the liquid, thereby completing the foaming process.

[0035] In another embodiment, the protective net 4 is provided with a plurality of arranged connecting groove structures, and the connecting groove structures are distributed on the side and bottom of the protective net 4. The connecting groove is in the shape of a long waist, and the connecting groove is arranged horizontally or tilted. When the connecting groove is tilted, the connecting groove is tilted upward along the rotation direction of the stirring head 21. At this time, the surface of the protective net 4 is a plurality of long waist-shaped connecting grooves, which can increase the overall area of the connecting grooves on the surface of the protective net 4, thereby reducing the influence of the protective net 4 on the flow of liquid. At the same time, the connecting groove is tilted, and the connecting groove is tilted upward along the rotation direction of the stirring head 21, that is, if the stirring head 21 rotates clockwise, then for a connecting groove, from the bottom position of the connecting groove, the upper end of the connecting groove gradually tilts upward in the clockwise direction, so that when the liquid flows clockwise, the resistance of the protective net 4 to the liquid will be smaller.

[0036] Since the stirring head 21 is connected to the motor via a connecting rod 22, and the stirring rod passes through the annular heating tube 31, in this embodiment, the stirring head 21 and the connecting rod 22 are fixedly connected or detachably connected. If the stirring head 21 is smaller than the inner diameter of the annular heating tube 31, the stirring head 21 can be directly fixedly connected to the connecting rod 22, and the connecting rod 22 is then connected to the motor shaft, thereby completing the installation of the stirring device 2. If the stirring head 21 is larger than the inner diameter of the annular heating tube 31, the stirring head 21 and the connecting rod 22 can be detachably connected (for example, threadedly connected), and the connecting rod 22 is then connected to the motor shaft, thereby completing the installation of the stirring device 2.

[0037] As for the heating device, the main part is the annular heating tube 31 arranged on the lower side of the shell 11. In this embodiment, the heating device is fixed to the shell 11 through a threaded connection or a snap connection.

[0038] Specifically, a positioning boss 32 is provided at the upper end of the annular heating tube 31, and a communicating hole is provided at the bottom of the housing 11. The annular heating tube 31 is fixed to the communicating hole of the bottom shell at the positioning boss 32, thereby fixing the annular heating tube 31 to the housing 11. Furthermore, a nut sleeve 33 is sleeved on the outer side of the annular heating tube 31, and the positioning boss 32 is located above the communicating hole. The nut sleeve 33 is threadedly connected to the annular heating tube 31, thereby fixing the annular heating tube 31 to the housing 11.

[0039] In another embodiment, a milk frother is provided, which uses the milk frother stirring rod of the above embodiment. The milk frother also includes a cup body 5, the milk frother stirring rod body 1 is located on the upper side of the cup body 5, and the stirring device 2 is located inside the cup body 5. Of course, the milk frother stirring plate can be adapted to other cup bodies 5 during use and can still be used normally.

[0040] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
