[0026] Refer to the following Figure 1-Figure 6 An air conditioning structure of a milk frothing device according to some embodiments of the present application is described.

[0027] An air conditioning structure of a milk frothing device comprises a milk box 1, a milk frothing machine 2 is arranged above the milk box 1, a milk frothing chamber 3 is arranged in the milk frothing machine 2, and an air inlet end 4, a steam inlet end 5, a milk inlet end 6 and a milk frothing end 7 are communicated with the milk frothing chamber 3. Steam enters the milk frothing chamber 3 from the steam inlet end 5, and under the action of the Venturi effect, drives the external air from the air inlet end and the milk in the milk box from the milk inlet end 6 to enter the milk frothing chamber respectively, and then the milk froth is discharged from the milk frothing end 7 after mixing and frothing.

[0028] The air intake end 4 is provided with an air conditioning structure, which includes an adjusting knob 8 and an air intake sleeve 9. The air intake sleeve 9 is fixedly arranged at the air intake end 4. The air intake sleeve 9 is provided with an air intake channel 21. The outlet of the air intake channel is connected to the inlet of the air intake end 4. The adjusting knob 8 is connected to a rotating shaft 11. An adjusting sleeve 12 is provided at the end of the rotating shaft 11. The adjusting sleeve 12 is embedded in the air intake sleeve 9. Rotating the adjusting knob 8 drives the rotating shaft 11 to rotate, thereby causing the adjusting sleeve 12 to rotate in the air intake sleeve 9.

[0029] The inlet of the air inlet channel 21 is an air inlet slit 10 provided on the inner wall of the air inlet sleeve 9, and the extension direction of the air inlet slit 10 is perpendicular to the rotation direction of the adjustment sleeve 12. The outlet of the air inlet channel 21 is provided with a guide block 22 that can be plugged into the inlet of the air inlet end 4, and the guide block 22 is provided with a guide hole 23 that connects the inlet of the air inlet end 4 and the air inlet channel 21. The guide block 22 is plugged into the inlet of the air inlet end 4, which can not only realize the positioning and fixing of the air inlet sleeve 9 at the air inlet end 4, but also improve the air tightness of the connection between the air inlet sleeve 9 and the air inlet end 4.

[0030] The adjusting sleeve 12 rotates in the air inlet sleeve 9 to have a first position and a second position. At the same time, the inner wall of the adjusting sleeve 12 is provided with a first air hole 13 connected to the air inlet slit 10 when it is rotated to the first position, and a second air hole 14 connected to the air inlet slit 10 when it is rotated to the second position. The first air hole 13 and the second air hole 14 have different apertures. Therefore, the adjusting knob 8 can realize that two different air volumes, large and small, enter the milk foam chamber 2 from the air inlet end 4 to produce two different milk foams. At the same time, the air inlet slit 10 is used to cooperate with the first air hole 13 and the second air hole 14 to communicate quickly and accurately to connect the air inlet channel 21, overcoming the problem that the air inlet channel 21 is easily blocked due to alignment deviation when the holes are connected.

[0031] A first stop block 15 and a second stop block 16 corresponding to the first position and the second position are provided on the side wall of the air intake sleeve 9 facing the rotating shaft 11. A limit block 17 is also provided at the end of the rotating shaft 11. The limit block 17 rotates between the first stop block 15 and the second stop block 16 as the rotating shaft rotates, thereby achieving accurate positioning of the first position and the second position.

[0032] The milk frother 2 includes a fixed tube 18, a rotating tube 19 and a rotating handle 20. The rotating tube 19 is sealedly connected to the fixed tube 18. The end of the rotating tube 19 is connected to the rotating handle 20. The rotating tube 19 is connected to the milk frothing end 7. Rotating the rotating handle 20 causes the rotating tube 19 to rotate and drives the outlet of the milk frothing end 7 to move closer to or away from the outer wall of the milk box 1.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
