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 utility model is suitable for the technical field of chemical production auxiliary equipment, and provides a chemical safety isolation device which comprises a base. The protection box is fixed at the top of the base and is used for isolating a chemical operation environment; the bulletproof glass plate is detachably mounted on the protection box through bolts and used for sealing the protection box, and the bulletproof glass plate is further used for assisting personnel in observing the machining progress; the rubber glove is detachably mounted on the bulletproof glass plate through a mounting block and is used for providing an operation channel; and the adjusting assembly is arranged on the base and used for adjusting the position of the chemical raw materials according to production requirements. According to the chemical safety isolation device provided by the scheme, a chemical processing environment can be isolated, and meanwhile, personnel can operate chemical raw materials on the premise of ensuring safety isolation.
