[0036] Currently, with the growing demand for high-quality coffee beverages, automatic milk dispensers on coffee machines are gaining popularity due to their ability to automatically froth milk. In existing technology, automatic milk dispensers typically include a high-temperature steam system that injects high-temperature steam mixed with air into the milk to create foam. This process aims to mimic the hand-frothing method to meet coffee enthusiasts' demands for fineness and consistency in the milk foam.

[0037] Existing coffee machines have a technical problem: they cannot adjust the amount of milk fed in, and therefore cannot adjust the temperature of the milk foam.

[0038] Please refer to Figures 1-6 This embodiment provides a milk frothing device and a coffee machine, which can effectively improve the technical problems mentioned above. It can automatically adjust the air intake volume, thereby adjusting the density and thickness of the milk foam, resulting in better performance.

[0039] The coffee machine includes a body and a milk frothing device, which is connected to the body. The body includes an upper cover 103 and a lower shell 104, which are detachably connected.

[0040] Please refer to Figures 1-6 The milk frothing device includes a bottle body 90, a foaming section 10, a milk straw 20, and a steam connector 30. The foaming section 10 is disposed in the bottle body 90, and the milk straw 20 is inserted into the bottle body 90. The foaming section 10 has a steam inlet 101 and a milk inlet 102 that are interconnected. The milk straw 20 is connected to the milk inlet 102, and the steam connector 30 is connected to the steam inlet 101. The steam connector 30 is rotatably disposed relative to the foaming section 10. The steam connector 30 has a blocking part 40, the position of which corresponds to the position of the milk inlet 102. The blocking part 40 is used to rotate with the steam connector 30, thereby adjusting the amount of milk entering the foaming section 10 through the milk inlet 102.

[0041] In this embodiment, the foaming section 10 includes a foaming cavity 11, a second sealing sleeve 12, and an air inlet pipe 13 that are interconnected. A steam inlet 101 and a milk inlet 102 are both located in the foaming cavity 11. The air inlet pipe 13 is connected to the foaming cavity 11, and the second sealing sleeve 12 is located inside the air inlet pipe 13. Specifically, the steam inlet 101 is located at one end of the foaming cavity 11, and the milk inlet 102 is located at the middle of the bottom of the foaming cavity 11. The steam connector 30 and the milk inlet 102 are perpendicular to each other, and the second sealing sleeve 12 is engaged with the air inlet pipe 13.

[0042] Specifically, the second sealing sleeve 12 is provided with a buckle, and the air intake pipe 13 is provided with a groove. The buckle engages with the groove, thereby achieving the engagement of the second sealing sleeve 12 and the air intake pipe 13. Of course, in other embodiments, a groove can be provided on the second sealing sleeve 12, and a buckle can be provided on the air intake pipe 13. No specific limitation is made here.

[0043] It should be noted that the steam connector 30 includes a connected steam pipe 31 and a steam knob 32. The steam pipe 31 is inserted into the steam inlet 101, and the blocking part 40 is disposed at the end of the steam pipe 31 located inside the foaming part 10. The steam knob 32 is used to drive the steam pipe 31 to rotate. Specifically, the blocking part 40 has a plate-like structure and is used to rotate with the steam connector 30, thereby gradually blocking the milk inlet 102 and thus changing the amount of milk entering the milk inlet 102.

[0044] Furthermore, the shielding part 40 can be L-shaped, so that the cross-section of the shielding part 40 changes as it rotates with the steam connector 30, thereby changing the amount of milk entering the milk inlet 102. In other embodiments, the shielding part 40 can also be T-shaped or other shapes, which are not specifically limited here.

[0045] In this embodiment, the milk frothing device further includes a first sealing sleeve 50, which is disposed at the end where the milk straw 20 connects to the milk inlet 102. The first sealing sleeve 50 can seal the gap between the milk straw 20 and the frothing chamber 11, preventing negative pressure leakage and thus avoiding poor milk adsorption effect.

[0046] Furthermore, the milk frothing device also includes a limiting member 60, which is disposed inside the first sealing sleeve 50 to prevent the first sealing sleeve 50 from deforming, thereby avoiding deformation of the outlet of the milk connector, which would result in poor milk adsorption.

[0047] In this embodiment, the limiting member 60 is a metal ring. The metal ring is disposed on the inner wall of the end of the first sealing sleeve 50 away from the milk straw 20, thereby supporting the first sealing sleeve 50 and preventing the first sealing sleeve 50 from deforming.

[0048] Furthermore, the milk frothing device also includes an air conditioning connector 70, which is rotatably connected to the foaming section 10. The air conditioning connector 70 is fitted inside the second sealing sleeve 12 and is used to adjust the air intake volume into the foaming section 10 when rotated. Specifically, the air conditioning connector 70 includes a connector body 71 and an adjustment knob 72. The adjustment knob 72 is installed on the connector body 71, which has an air intake channel that communicates with the foaming section 10. The adjustment knob 72 is used to rotate the connector body 71, thereby rotating the air intake channel to adjust the air intake volume into the foaming section 10. The adjustment knob 72 is located on the top of the connector body 71, outside the upper cover 103, and can rotate relative to the upper cover 103. The connector body 71 is located in the receiving space formed by the upper cover 103 and the lower shell 104. The outer surface of the adjustment knob 72 has multiple protrusions to increase the friction during rotation.

[0049] In this embodiment, the inner wall of the second sealing sleeve 12 is provided with a through hole, which is connected to both the air intake channel and the air intake pipe 13.

[0050] In this embodiment, both the first sealing sleeve 50 and the second sealing sleeve 12 are silicone sleeves.

[0051] During operation, after steam is introduced into the foaming chamber 11 through the steam connector 30, a negative pressure is created inside the foaming chamber 11. This draws milk from the bottle 90 through the milk straw 20 and the milk inlet 102 into the foaming section 10, allowing the milk and high-temperature steam to mix and foam. Figure 5 As shown, at this time, the steam connector 30 is at the lowest milk foam temperature. At this time, the milk intake is the largest, and the milk foam produced by the large amount of milk and high-temperature steam mixed in the foaming chamber 11 has the lowest temperature.

[0052] When a higher milk foam temperature is needed, turn the steam knob 32 so that part of the obstruction part 40 is positioned at the milk inlet 102, blocking one-third of the area of ​​the milk inlet 102, thus preventing some milk from entering. At this point, the milk intake is moderate, and the temperature of the milk foam produced by mixing with the high-temperature steam in the foaming chamber 11 is relatively moderate. Continue turning the steam knob 32, as... Figure 6 As shown, at this time, the steam connector 30 is at the highest milk foam temperature, and the shielding part 40 is completely located at the milk inlet 102, thus blocking half of the area of ​​the milk inlet 102, thereby blocking most of the milk from entering. At this time, the milk intake is small, and the temperature of the milk foam produced by the small amount of milk entering the foaming chamber 11 mixed with the high temperature steam is relatively the highest.

[0053] Furthermore, the milk frothing device also includes a milk outlet connector 80, which is connected to the frothing section 10 for outputting frothed milk.

[0054] In summary, this utility model provides a milk frothing device and a coffee machine. The milk frothing device includes a frothing section 10, a milk straw 20, and a steam connector 30. The frothing section 10 is provided with a steam inlet 101 and a milk inlet 102 that are interconnected. The milk straw 20 is connected to the milk inlet 102, and the steam connector 30 is connected to the steam inlet 101. The steam connector 30 is rotatably arranged relative to the frothing section 10. The steam connector 30 is provided with a blocking part 40, the position of which corresponds to the position of the milk inlet 102. The blocking part 40 is used to rotate with the steam connector 30, thereby adjusting the amount of milk entering the frothing section 10 through the milk inlet 102. In use, the steam connector 30 and the milk straw 20 are connected to the steam inlet 101 and the milk inlet 102 of the foaming section 10, respectively. After high-temperature steam is introduced into the steam connector 30, a negative pressure is generated in the foaming section 10, thereby drawing milk into the foaming section 10 through the milk straw 20 and the milk inlet 102 for foaming. The steam connector 30 is provided with a shielding part 40, and the position of the shielding part 40 corresponds to the position of the milk inlet 102. By rotating the steam connector 30, the shielding part 40 is rotated, thereby adjusting the amount of milk entering the foaming section 10 through the milk inlet 102, and finally adjusting the temperature of the milk foam to improve the milk foaming effect.

[0055] The coffee machine includes a main body and a milk frothing device connected to the main body. In use, the steam connector 30 and milk straw 20 are connected to the steam inlet 101 and milk inlet 102 of the frothing section 10, respectively. High-temperature steam is introduced into the steam connector 30, creating negative pressure within the frothing section 10. This draws milk into the frothing section 10 through the milk straw 20 and milk inlet 102 for frothing. The steam connector 30 has a shielding part 40, whose position corresponds to the position of the milk inlet 102. Rotating the steam connector 30 causes the shielding part 40 to rotate, thereby adjusting the amount of milk entering the frothing section 10 through the milk inlet 102, ultimately adjusting the temperature of the milk foam and improving the frothing effect.

[0056] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
