Abstract:
1. A blender lid safety protection device comprising: a female embedding base with a hollow interior formed in a space on an external side of a mixing cup of a blender, with a notch formed at a rear end of the female embedding base, with a control switch installed at a bottom of the mixing cup; a link rod downwardly extended along an external wall of the mixing cup, with the link rod having a top end extended into the female embedding base and a bottom end extended into the bottom of the mixing cup, with the control switch installed with a predetermined distance from the bottom end of the link rod, with the female embedding base having a through hole formed at a top of the female embedding base and corresponding to the top end of the link rod, with a transverse slot penetrated and passed between the corresponding sidewalls of the through hole; a spring passed and installed to the link rod and providing an elastic force for pushing and maintaining the link rod upward, with the bottom end of the link rod maintained at a position with the predetermined distance from the control switch below; a blender lid covered onto a top of the mixing cup and having a male embedding base outwardly extended from a corresponding side of the female embedding base and embedded and coupled to an external side of the female embedding base, with a pushing plate downwardly extended from an internal ceiling of the male embedding base and corresponding to the top end of the link rod and a position at the through hole on the top of the female embedding base, with the male embedding base corresponding to the notch at the rear end of the female embedding base, with an opening formed on an external sidewall of the blender lid, with inwardly concave guide rails installed on corresponding internal walls of the male embedding base corresponding to the transverse slot of the female embedding base respectively, with the guide rail having a horizontal section and a vertical section interconnected to the horizontal section, and with the vertical section disposed closer to the mixing cup than the horizontal section; and a latch cover mechanism embedded into the female embedding base and having a latch base driven and displaced transversally, with a spring moving the latch base outward, with the latch base having a push handle installed at an end of the notch corresponding to the rear end of the female embedding base, with an end of the push handle extended out through the notch, with the latch base having two parallel side wings extended and protruded towards an end of the mixing cup, and with a latch pellet protruded separately from the two parallel side wings and aligned towards ends of the transverse slot of the female embedding base respectively, wherein after the latch pellet is passed through the transverse slot of the female embedding base, a distal portion is embedded into the guide rail of the male embedding base of the blender lid to install the latch base in the female embedding base.
