Waterproof device for household remote controller

The invention discloses a waterproof device for a household remote controller, and relates to the field of household articles. The device comprises a waterproof cover, a movable hinge, and a sealed pedestal. The left end of the sealed pedestal is provided with a second support seat, and the right end of the sealed pedestal is provided with a rotary knob support seat. The bottom of the waterproof cover is installed at the upper end of the sealed pedestal in a buckling manner. The left end of the waterproof cover is fixedly connected with an upper pressing block, and the middle portion of the upper end of the rotary knob support seat is connected with the rear end of the waterproof cover through the movable hinge. After the remote controller is placed on a protective cover shell and the protective cover shell is buckled on the sealed pedestal, the protective cover shell is pressed so as to press a main transmission mechanism so that a second transmission mechanism is linked with a linkage mechanism through a third transmission mechanism, a fourth transmission mechanism is enabled to drive an ejection device to rotate, and finally a lifting device is controlled to drive a push plate to rise, thereby driving a platform locking mechanism to lock the protective cover shell, effectively preventing the water from being splashed to the remote controller accidentally during family activities, prolonging the service life of the remote controller and protecting the health of family members.
