Toilet seat with delay suction release and automatically stand upright

A toilet seat with delay suction release and automatically stand upright, comprising a rotary toilet seat rotatably connected to a toilet base, and a rotating shaft sleeve provided with a hydraulic hinge inside fixed at an end of the rotary toilet seat, wherein a delay suction release and automatically stand upright control device allowing the rotary toilet seat to automatically stand up relative to the toilet base is provided on the rotary toilet seat;

• the delay suction release and automatically stand upright control device comprises a sucker assembly for delay suction release set on the rotary toilet seat and a hinge driving assembly configured to drive the rotary toilet seat to rotate and raise up;
• the sucker assembly comprises a hard mounting frame fixed at a bottom of a side of the rotary toilet seat and a sucker body detachably fixed on the hard mounting frame, wherein the sucker body cooperates with a contact surface of the toilet base to form a sealed space;
• the sucker body comprises a sucker connection part connected to an inner wall of the hard mounting frame and a suction part connected to a lower end of the sucker connection part;
• a deformable top plate is provided at a top of the sucker connection part, and an elastic ventilation cut is provided on the deformable top plate to communicate an interior of the sucker body with an air guide channel;
• the hinge driving assembly comprises a fixed rotary arm fixed on each of both sides of the toilet base, a transverse support shaft provided on the fixed rotary arm, and a driving torsion spring provided on the transverse support shaft, wherein the transverse support shaft is fixedly connected to a rotating shaft core of the hydraulic hinge, a fixed end of the driving torsion spring is fixed to the fixed rotary arm, and a driving end of the driving torsion spring is fixed to an inner wall of the rotating shaft sleeve;
• and
• when the rotary toilet seat is not under pressure, an external atmosphere slowly enters the suction part through the air guide channel of the sucker assembly from the elastic ventilation cut, causing a suction force between the suction part and the toilet base to gradually decrease, until a rotational elastic force of the driving torsion spring of the hinge driving assembly is greater than the suction force of the suction part, the driving torsion spring drives the rotary toilet seat to automatically open upwards relative to the toilet base.
