DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal connections between two components; they may refer to wireless connections or wired connections. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] According to the first aspect, the embodiment of the present utility model discloses a milk frothing head, such as Figure 1-11 As shown, it includes: a first and a second beating frame 2 that are detachably connected. One end of the first beating frame 1 is provided with a connecting rod 11 for connecting to an external power device. A filter 3 is installed between the first and second beating frames 1 and 2. The head end of the filter 3 is connected to the tail end, and the filter 3 is arranged in a ring shape. The first beating frame 1 is provided with a first through-hole 12, and the second beating frame 2 is provided with a second through-hole 21 corresponding to the first through-hole 12. In this embodiment, the first beating frame 1 is provided with an insertion rod 13 at one end relative to the connecting rod 11, and the second beating frame 2 is provided with a slot 22 that is plugged into and cooperates with the insertion rod 13, and the insertion rod 13 passes through the slot 22. The outer wall of the insertion rod 13 is provided with a first plane 131, and the slot 22 is provided with a second plane 221 that is in contact with the first plane 131. The arrangement of the first plane 131 and the second plane 221 facilitates the first beating frame 1 to drive the second beating frame 2 to rotate synchronously.

[0034] It should be noted that a filter 3 is installed between the first whipping frame 1 and the second whipping frame 2. When the milk frothing head rotates, the bubbles are divided into several small bubbles by the filter 3. The small bubbles form delicate and dense milk foam with the milk, thereby providing a milk frothing head that does not require an impeller structure, reduces the risk of excessive air intake, has a simple overall structure, simplifies the structure of the milk frothing head, and is easy to clean.

[0035] like Figure 3 As shown, the inner diameter of the upper opening of the filter 3 is the same as that of the lower opening of the filter 3. It should be noted that since the filter 3 is placed vertically, its axial position has been changed from perpendicular to the milk frothing head to parallel to the axial position of the milk frothing head, which increases the area of ​​the filter 3, allowing more air and milk to quickly pass through the filter 3 to form milk foam, effectively increasing the efficiency of large milk foam.

[0036] like Figure 9As shown, the inner diameter of the upper opening of the filter 3 is larger than the inner diameter of the lower opening of the filter 3. It should be noted that since the inner diameter of the upper opening of the filter 3 is larger than the inner diameter of the lower opening of the filter 3, the area of ​​the filter 3 is increased, allowing more air and milk to quickly pass through the filter 3 to form milk foam, effectively increasing the efficiency of large milk foam; and preventing collision with the bottom of the milk storage container.

[0037] like Figure 4 As shown, the filter screen 3 is made of stainless steel. In the specific implementation process, the filter screen 3 is made by etching holes on a complete thin metal sheet. Compared with the traditional woven mesh structure, the filter screen 3 has no gaps and is more convenient to clean.

[0038] like Figure 4 As shown, the head end of the filter screen 3 is welded to the tail end of the filter screen 3. It should be noted that since the head end of the filter screen 3 is welded to the tail end of the filter screen 3, the structure of the filter screen 3 is more stable.

[0039] like Figure 4-6 As shown, the filter screen 3 is provided with a first positioning piece 31, and the first beating frame 1 or the second beating frame 2 is provided with a first positioning groove 4 adapted to the first positioning piece 31. It should be noted that the first positioning piece 31 and the filter screen 3 are an integrally formed structure, and the filter screen 3 can be positioned and installed by the positioning cooperation between the first positioning piece 31 and the first positioning groove 4.

[0040] like Figure 4-6 As shown, the filter screen 3 is provided with a second positioning piece 32 positioned opposite the first positioning piece 31, and the first or second sending frame 1 is provided with a second positioning groove 5 adapted to the second positioning piece 32. It should be noted that the second positioning piece 32 and the second filter screen 3 are integrally formed. The positioning and cooperation between the second positioning piece 32 and the second positioning groove 5 allow the filter screen 3 to be positioned and installed. In a specific implementation, the first positioning piece 31 is located in the middle of one side of the filter screen 3, and the second positioning piece 32 is located at the end. There are two second positioning pieces 32.

[0041] like Figure 1-11 As shown, the number of filters 3 is set to be multiple, and the multiple filters 3 are arranged in layers from the inside to the outside. It should be noted that when the filters 3 rotate at high speed, a strong centrifugal force is generated in the milk, forcing the milk and bubbles to pass through the etched filter 3. The bubbles are divided into countless small bubbles and mixed with the milk, thus forming a fine and dense milk foam.

[0042] According to a second aspect, the present invention discloses a bubbler, such as Figure 10 and Figure 11As shown, it includes: a frothing motor, a transmission shaft 6 and a milk frothing head as in the first aspect, one end of the transmission shaft 6 is connected to the connecting rod 11, and the other end of the transmission shaft 6 is connected to the output shaft of the frothing motor.

[0043] like Figure 10 and Figure 11 As shown, the transmission shaft 6 is a hollow shaft, and a shock absorber 7 is installed inside the transmission shaft 6 to reduce the vibration of the transmission shaft 6. In this embodiment, the shock absorber 7 is a counterweight. Through the provision of the counterweight, due to the different rotation speeds of the transmission shaft 6 and the counterweight in the initial stage of rotation, the counterweight and the transmission shaft 6 collide with each other, offsetting the resonance of the transmission shaft 6, thereby reducing the vibration and enhancing the user experience.

[0044] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
