Electrical milk frother i.e. battery operated milk frother, has half-spherical lower side made of high density material, where position of frother is changed with respect to effect of external gravity forces such that centroid is raised
摘要
<p>The frother has batteries (F) and a half-spherical lower side (A) that is made of a high density material i.e. metal. Centroid of a lower side lies below an upper edge (G) of the half-spherical lower side. A position of the frother is changed with respect to an effect of external gravity forces such that centroid is raised. Connecting elements of the batteries are completely or partially positioned in the half-spherical lower side, where the batteries are rechargeable.</p>
