Abstract
A blender lid safety protection device includes a latch cover mechanism installed outside a mixing cup, such that after a lid is covered vertically onto the mixing cup, the lid is latched and fixed to the latch cover mechanism. A link rod has a compression spring coupled to the bottom of the link rod for propping the bottom of the link rod to a certain distance from one of the control switches of a power circuit control switch. After the blender lid is pressed down, the top end of the link rod drives the compression spring at the bottom of the link rod to move downward to trigger a control switch. Only after the blender lid is covered onto the mixing cup, the control switch of one of the power circuit switches will be electrically conducted, to provide a safety protection.
