Automatic unblocking mechanism for urinal

The invention discloses an automatic unblocking mechanism for a urinal. The automatic unblocking mechanism comprises a urinal body, wherein a urina drainage channel is arranged at the bottom inside the urinal body; the side wall of the urina drainage channel is connected with a urina drainage pipe connected to the outside; a cover plate is placed at the inner bottom of the urinal body; an L-shapedwater drainage pipe is mounted on the side wall of the urinal body; the inner wall of the bottom of the urinal body is slidably connected with a liquid storage box; the lower end of the L-shaped water drainage pipe extends to the interior of the liquid storage box; the liquid storage box is internally covered with a baffle screen; the bottom of the liquid storage box and the inner bottom of the urinal body through a spring elastically; the liquid storage box and the urina drainage channel are communicated through a connecting pipe; the bottom of the liquid storage box and the urina drainage pipe are connected through a liquid outlet hose; the urina drainage channel is internally provided with a piston; a propping rod is fixedly arranged at the upper end of the piston; and the upper end ofthe propping rod is fixedly connected with the cover plate. The automatic unblocking mechanism is reasonable in structure, unblocking can be carried out automatically when the urinal is blocked, andimpurities can be collected.
