(1) preparing cold milk foam: the air control valve 22 and the second control valve 12 are opened, the cold fresh milk in the milk supply device 1 and the air in the air supply device 2 are pumped to the nozzle 4 through the pump body 3, at the moment, the air in the nozzle 4 can be squeezed and torn into small bubbles to be mixed into the cold fresh milk to form cold milk bubbles, then the cold milk bubbles pass through the elongated output pipeline 6, and the cold milk bubbles in the output pipeline 6 cannot be heated due to the fact that the steam control valve 74 is in a closed state at the moment, and therefore the milk bubbles prepared by the milk bubble preparation system are the cold milk bubbles.

(2) Preparing cold fresh milk: compared with the preparation process of the cold milk foam, the cold fresh milk can be prepared only by closing the air control valve 22.

(3) Preparing hot milk foam: the air control valve 22, the second control valve 12 and the steam control valve 74 are opened, the cold fresh milk in the milk supply device 1 and the air in the air supply device 2 are pumped to the nozzle 4 through the pump body 3, at the moment, the air in the nozzle 4 can be extruded and torn into small bubbles to be mixed into the cold fresh milk to form cold milk bubbles, then the cold milk bubbles pass through the elongated output pipeline 6, and because the steam control valve 74 is in an open state at the moment, steam can be introduced into the heating pipeline 7 to heat the cold milk bubbles in the output pipeline 6, so that the milk bubbles prepared by the milk bubble preparation system are hot milk bubbles.

(4) Preparing hot milk: with respect to the preparation of hot milk foam, hot milk can be prepared by only closing the air control valve 22.

As shown in fig. 5, in this embodiment, in order to prevent heat generated by steam introduced into the heating pipeline 7 from being quickly dissipated to the external environment and prevent safety accidents caused by damage to the heating pipeline 7 or the output pipeline 6 due to excessive pressure inside the heating pipeline 7 caused by excessive steam introduction, the foamed milk preparation system further includes a first controller 8a and a pressure sensor 8b electrically connected to the first controller 8 a. Specifically, the second outlet 72 is provided with a first control valve 8c, the pressure sensor 8b is disposed in the heating pipeline 7 and configured to sense the pressure in the heating pipeline 7 and send a sensing signal to the first controller 8a, and the first controller 8a is configured to control the opening and closing of the first control valve 8c according to the sensing signal so as to adjust the pressure in the heating pipeline 7. That is, when the pressure sensor 8b senses that the pressure in the heating pipeline 7 rises to a certain pressure value, a corresponding sensing signal is generated and sent to the first controller 8a, and the first controller 8a at this time controls the first control valve 8c to be automatically opened according to the sensing signal, so as to discharge the steam in the heating pipeline 7. And when pressure sensor 8b sensed the inside pressure reduction of heating pipeline 7 to certain pressure value, can generate corresponding sensing signal and send this sensing signal to first controller 8a, first controller 8a this moment just can be according to this sensing signal control this first control valve 8c self-closing, prevents the steam discharge in the heating pipeline 7, prevents that the heat from spreading external environment, and is energy-conserving high-efficient.

In this embodiment, since the milk and the milk foam may remain on the inner wall of the pipeline when flowing through the pipeline, the pipeline of the milk foam preparation system is usually cleaned to ensure the cleanness of the pipeline. Therefore, the foamed milk preparation system further comprises a second connecting duct 9. Specifically, one end of the second connecting pipe 9 is connected to the air conveying pipe 21 or the milk conveying pipe 11, and the other end of the second connecting pipe 9 is used for connecting the cleaning device 9a, so that the second connecting pipe 9 can be used for conveying the liquid in the cleaning device 9a to the air conveying pipe 21 or the milk conveying pipe 11, and then conveying the liquid in the cleaning device 9a to other pipes of the milk foam preparation system through the air conveying pipe 21 or the milk conveying pipe 11, for example: a first connecting duct 5, an output duct 6, etc. That is, when one end of the second connection pipe 9 is connected to the air delivery pipe 21, the liquid in the washing device 9a may be delivered to the milk delivery pipe 11, the first connection pipe 5, and the output pipe 6 through the air delivery pipe 21; and when one end of the second connection pipe 9 is connected to the milk delivery pipe 11, the liquid in the washing device 9a may be delivered to the air delivery pipe 21, the first connection pipe 5, and the output pipe 6 through the milk delivery pipe 11.

Wherein, the liquid can be clear water or a mixed liquid of water and a cleaning agent. It should be noted that when the liquid in the cleaning device 9a is a mixed liquid of water and detergent, the cleaning device needs to be cleaned again with clean water after cleaning to clean the residual detergent in the pipeline.

It will be appreciated that during cleaning of the line, the steam control valve 74 may also be opened to introduce steam into the heating conduit 7 to heat the liquid in the outlet conduit 6, which may be beneficial to improve the cleaning efficiency of the cleaning of the outlet conduit 6.

Preferably, one end of the second connection pipe 9 may be connected to the air delivery pipe 21, and the second connection pipe 9 may be provided with a third control valve 91, and the third control valve 91 may be used for controlling the connection of the second connection pipe 9 and the air delivery pipe 21. And in order that the preparation of milk foam or milk and the cleaning of the lines may be performed separately, it may be preferred that the third control valve 91 is interlocked with the second control valve 12. That is, when the third control valve 91 is activated, the second control valve 12 is closed; and the third control valve 91 is closed, the second control valve 12 is actuated.

Further, as shown in fig. 6, in order to automatically clean the piping of the foamed milk preparation system, the foamed milk preparation system further includes a second controller 8d and a detector 8e electrically connected to the second controller 8 d.
