The invention discloses an discharging device of a toilet bowl and belongs to the technical field of equipment for bathrooms. The discharging device comprises a valve base. The valve base is provided with an upper through hole and a low through hole which are through vertically. A valve element is arranged inside the valve base. The valve element is movably matched with the valve base in a radial-penetrating mode. A through hole is formed in the valve element. An discharging channel is formed when the upper through hole, the through hole and the lower through hole are communicated. A sealing assembly is arranged at the position of the upper through hole. The sealing assembly and the upper surface of the valve element form sealing. The discharging and flushing actions are linked by adopting a pure mechanical mechanism, the structure is compact, and use is convenient and easy; a high pressure water flushing toilet bowl is adopted directly, more water is saved, environmental protection is achieved better, the energy conservation and emission reduction effects are achieved better, the toilet bowl is not stained or plugged, and flushing is thorough and more sanitary; due to the arranged sealing assembly, the sealing performance is good, and it can be ensured that the toilet bowl does not stink; a pedal is supported by a pivot, no force is borne at the joint by adopting a middle cross bar, abrasion is small, the service life of the discharging device is long.
