Blender having a top cover provided with a switch actuating block

A blender includes a motor base, a container, and a top cover. The motor base includes a motor unit having a blade driving section, and a contact switch unit connected electrically to the motor unit. The contact switch unit includes a press button that is depressible so as to permit activation of the motor unit. The container has a container bottom provided with a cutting blade unit that is coupled to the blade driving section so as to be driven rotatably by the motor unit. The container has a spring-loaded push rod unit mounted movably thereon. The push rod unit has a bottom rod section associated with the press button of the contact switch unit, and a top rod section depressible by a switch actuating block of the top cover so as to move the push rod unit against biasing action from a deactivating position to an activating position.
