[0039] Specifically, in this actual example, a positive-displacement pump such as a diaphragm pump, a peristaltic pump, a gear pump, or a rotary pump is used to whip the milk froth by its own suction structure. Other positive-displacement pumps can also be used as long as they can evacuate and suck milk by themselves and can intake air at the same time. The preliminary whipping of the milk froth can be carried out. The thrust of the cold milk froth by the power pump 11 provides fluid power, and then the cold milk froth is secondarily whipped by driving the rotor 32 through the fluid power. The milk is directly sucked into the mixing cavity inside the diaphragm pump from the milk inlet 13 by a 5V four-chamber diaphragm pump. At the same time, the diaphragm pump sucks in air from the air inlet. The diaphragm pump uses the diaphragm inside itself to squeeze the air and milk for mixing to form a preliminary coarse milk froth, and then the milk froth is directly discharged from the small-diameter milk outlet 15, enters the rotor assembly 3 through the connection pipe 2, uses the ejection speed of the milk from the diaphragm pump to drive the rotor 32 to rotate, drives the spring coil 35 fixed together with the rotor 32 to whip the milk froth again, and then is discharged into the milk frothing pipe fitting 51 through the milk frothing pipe 53, and finally is discharged from the milk frothing port 52. Finally, the whipping of the cold milk froth is completed.

A milk storage box 6 is arranged inside the fixed housing 7 and below the housing 4. A milk supply pipe 61 is connected to the upper end of the milk storage box 6. One side of another interface on the connecting piece of the fixed housing 7 is connected to the milk supply pipe 61, and the other side of this interface is connected to the milk inlet pipe 12. The milk supply pipe 61 communicates the milk storage box 6 and the milk inlet pipe 12 to suck milk into the mixing chamber of the power pump 11. The power pump 11 provides air and power, and air intake and milk intake are carried out simultaneously. The milk and air are rotated, squeezed, and centrifuged inside the pump to be mixed. When reaching a certain flow rate, the rotor 32 is pushed to rotate to foam the milk for the second time. After passing through small holes with a certain aperture, large milk bubbles are eliminated, and finally cold milk foam flows out.

[0042] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
