The application discloses a milk frother for making delicate milk froth and relates to the technical field of milk frothing equipment. The milk frother comprises a milk froth generating system and an independent cleaning system. The milk froth generating system comprises a first three-way pipe fitting, a milk pump, a first heater and a multi-way switching valve assembly. The independent cleaning system comprises a second heater and a shunt structure of the multi-way switching valve assembly. In the cleaning mode, the high-temperature cleaning water output by the second heater is divided into a forward water flow and a reverse water flow. The forward water flow cleanses the milk pipeline. The reverse water flow flows reversely through the first heater, a filter joint and the milk pump in sequence and is finally discharged by a blow-off branch. The application realizes active aortic pulse air intake double frothing. By means of a double independent heating and bidirectional reverse flow cleaning architecture, the problems of pipeline dead angle milk scale residue and water-milk cross contamination are effectively solved.

The present disclosure provides a battery control device for a generator set and a vehicle, and relates to the technical field of generator sets, wherein the device comprises a first battery pack, a second battery pack, a negative electrode contactor, a positive electrode contactor and a change-over switch. One end of the negative electrode contactor is connected to the negative electrode of a first set starting motor and the negative electrode of a second set starting motor, and the other end is connected to the negative electrode of the first battery pack and the negative electrode of the second battery pack. One end of the positive electrode contactor is connected to the positive electrode of the first set starting motor and the positive electrode of the first battery pack, and the other end is connected to the positive electrode of the second set starting motor and the positive electrode of the second battery pack. The output end of the change-over switch is connected to the control end of the negative electrode contactor and the control end of the positive electrode contactor. When the change-over switch is in the first gear, the negative electrode contactor and the positive electrode contactor are disconnected. The device can effectively prevent the battery from being depleted, without the need for regular starting of the generator set or external charging maintenance of the battery.
