The present disclosure relates to the technical field of maternal and infant products, more specifically, to a brushless motor mounting structure of a milk-shaking seat and a milk shaker having the same.
During the infant and toddler stages, people usually choose milk powder to feed infants and toddlers to ensure healthy growth thereof. However, a lot of milk powder dissolves slowly and require a long time of manual shaking to enable full dissolution of the milk powder into water, so that the operation is very troublesome. To facilitate the shaking of the milk bottle and ensure that the milk powder is fully dissolved, people opt to use a milk shaker.
Currently, the motors of commonly-used milk shakers are mostly mounted on the milk-shaking seat through a secondary mountingmounting structure.
