[0030] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0032] Reference Figures 1 to 5 As shown, a milk foam generating device includes a milk frother body 1, a liquid inlet structure 2, an air inlet structure 3, a milk foam output structure 4, and a cover 5.

[0033] The milk frother body 1 is provided with a mixing chamber 11, a milk channel 12 and an air channel 13;

[0034] The cover 5 is provided with a steam input pipe 51, a liquid input pipe 52 and an air input pipe 53. The steam input pipe 51 is inserted into the mixing chamber 11, and the inner cavity of the steam input pipe 51 forms a steam channel 14. The liquid input pipe 52 is inserted into the milk channel 12, and the air input pipe 53 is inserted into the air channel 13.

[0035] The steam channel 14 is connected above the mixing chamber 11, the milk foam output structure 4 is connected below the mixing chamber 11, and the milk channel 12 and the air channel 13 are respectively connected to the mixing chamber 11.

[0036] Both the liquid inlet structure 2 and the air inlet structure 3 are installed on the cover 5. The liquid inlet structure 2 is connected to the liquid input pipe 52, and the air inlet structure 3 is connected to the air input pipe 53.

[0037] The cover 5 is connected to the milk frother body 1 through the steam inlet pipe 51, the liquid inlet pipe 52, and the air inlet pipe 53, making it easy to disassemble and assemble. The liquid inlet structure 2 and the air inlet structure 3 are both located on the cover 5. Simply removing the cover 5 will open the mixing chamber 11, the milk channel 12, and the air channel 13, making cleaning convenient.

[0038] In this embodiment, the liquid inlet structure 2 includes a first liquid inlet channel 21 and a second liquid inlet channel 22, which are respectively connected to the liquid input pipe body 52;

[0039] The second liquid inlet channel 22 can be connected to an external milk supply unit, while the first liquid inlet channel 21 can be connected to an external clean water supply unit.

[0040] Steam is input through steam input pipe 51, liquid enters milk channel 12 through liquid input pipe 52, and air enters air channel 13 through air input pipe 53. When making milk foam, the external water supply unit can be turned off and the external milk supply unit can be turned on. Milk enters milk channel 12 through second liquid inlet channel 22 and then enters mixing chamber 11. Steam is input through steam channel 14 and air is input through air inlet structure 3 through air inlet structure 3. Steam, air and milk generate milk foam in mixing chamber 11 and then milk foam is output from milk foam output structure 4.

[0041] When cleaning is required, the external water supply unit can be activated and the external milk supply unit can be turned off, and no more milk will be input. Water enters the milk channel 12 from the first liquid inlet channel 21 and then enters the mixing chamber 11, which can clean the milk channel 12 and the mixing chamber 11. Water will also be output from the milk foam output structure 4, which will clean the milk foam output structure 4 simultaneously.

[0042] In this way, the difficulty of cleaning is reduced and the number of times disassembly and cleaning are reduced. Both the external milk supply unit and the external water supply unit have the function of preventing backflow after being turned off. Therefore, water will not enter the external milk supply unit, and milk will not enter the external water supply unit.

[0043] In this embodiment, the steam inlet pipe 51, the liquid inlet pipe 52, and the air inlet pipe 53 are all vertically installed on the cover 5; the liquid inlet structure 2 includes a first block 23, which is detachably installed on the cover 5. The first liquid inlet channel 21 and the second liquid inlet channel 22 are both disposed on the first block 23. The first liquid inlet channel 21 is sleeved on the liquid inlet pipe 52, and the second liquid inlet channel 22 is connected to the first liquid inlet channel 21.

[0044] The first liquid inlet channel 21 extends vertically to facilitate fitting onto the liquid inlet tube 52, while the second liquid inlet channel 22 extends horizontally. When milk is being inlet, the milk flows into the liquid inlet tube 52 through the second liquid inlet channel 22 and a portion of the first liquid inlet channel 21.

[0045] In another embodiment, the first liquid inlet channel 21 may not be fitted onto the liquid input tube 52. Instead, a groove can be provided in the first block 23 to fit the liquid input tube 52, and the first liquid inlet channel 21 and the second liquid inlet channel 22 can be connected to the groove respectively.

[0046] In this embodiment, the first block 23 is installed on the cover 5 by a snap-fit ​​mechanism. When necessary, the first block 23 can be easily removed and pulled out from the liquid inlet pipe 52.

[0047] In some other embodiments, the first block 23 can also be installed onto the cover 5 by bolts.

[0048] In this embodiment, the air intake structure 3 includes a second block 31, an air intake channel 32, and a rotating shaft 33. The second block 31 is detachably mounted on the cover 5. The air intake channel 32 is disposed in the second block 31 and sleeved on the air input pipe 53. The rotating shaft 33 passes through the second block 31, and the axis of the rotating shaft 33 is perpendicular to the axis of the air intake channel 32. The outer peripheral wall of the rotating shaft 33 is provided with an arc-shaped groove 331 whose depth gradually changes from small to large. The rotating shaft 33 passes through the middle of the air intake channel 32, and the arc-shaped groove 331 is used to connect the air intake channel 32.

[0049] The intake channel 32 also extends vertically. The rotating shaft 33 divides the intake channel 32 into an upper section and a lower section. The upper section and the lower section of the intake channel 32 are connected by the arc groove 331. Since the depth of the arc groove 331 gradually changes, rotating the rotating shaft 33 can control the size of the gap connecting the upper section and the lower section of the intake channel 32, thereby controlling the intake volume.

[0050] Of course, a handle is provided on the rotating shaft 33, and the rotating shaft 33 is rotated by the handle.

[0051] In this embodiment, the diameter of the air input pipe 53 is relatively large, while the inner diameter of the air intake channel 32 cannot be too large, otherwise the diameter of the rotating shaft 33 will be difficult to control. Therefore, a receiving hole adapted to the air input pipe 53 can be provided at the lower end of the air intake channel 32. The air intake channel 32 and the receiving hole are coaxial and connected. The air input pipe 53 can be inserted into the receiving hole, and the air intake channel 32 can be connected to the air input pipe 53.

[0052] In this embodiment, the second block 31 is installed on the cover 5 by a snap-fit ​​mechanism. When necessary, the second block 31 can be easily removed and pulled out from the air input pipe 53.

[0053] In some other embodiments, the second block 31 can also be installed onto the cover 5 by bolts.

[0054] In this embodiment, the milk frothing output structure 4 includes an output head 41, which is detachably mounted on the milk frother body 1. The output head 41 has a buffer chamber 411 and a foaming channel 412. The foaming channel 412 is connected to the buffer chamber 411 and located below the buffer chamber 411. The buffer chamber 411 is connected to the mixing chamber 11. The foaming channel 412 is offset from the mixing chamber 11. The structure also includes a baffle 15, which is an integral structure with the milk frother body 1. The baffle 15 is located in the buffer chamber 411 and partially obscures the mixing chamber 11. At the same time, the baffle 15 is located above the foaming channel 412.

[0055] After the milk foam is output from the mixing chamber 11, it impacts the baffle 15, making the milk foam denser. Then it enters the buffer chamber 411, which slows down the flow rate of the milk foam. After that, the milk foam flows out from the foaming channel 412 and spreads on the coffee.

[0056] The baffle 15 is set on the milk frother body 1, which makes the processing more convenient. If the baffle 15 is set on the output head 41, the structure of the output head 41 will be particularly complicated to process and the cost will be higher.

[0057] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
