Abstract: The present invention relates to kitchenware of electrical appliance, A milk frother comprises a container and an electrical base unit. The container is provided with a separating disc that divides the container into an upper cavity and a lower cavity. A stirrer with slave magnetic element is provided atop the separating disc. A heating device, a rotatable device and a motor are provided beneath the separating disc. the present invention utilizes a separating disc to completely insulate the upper cavity that holds milk and the working circuit that operates the stirrer so that milk will not leak into the bottom of container to affect working circuit and the lubricant of motor ii will not leak into the upper cavity to contaminate milk. So this scheme should provide a sanitary and safe milk frother. The use of magnets provides a clean and environment-friendly way to drive stirrer. The stirrer is just positioned in the upper cavity so that the stirrer can be more conveniently disassembled for cleaning.
