. The sealing ring and the inner wall of the sewage draining outlet form a group of brake devices. The sealing ring plays a role of a brake pad, and the inner wall of the toilet bowl sewage draining outlet plays a role of a brake hub.

After the water flushing of the piston is finished, the piston continues to rotate due to inertia, when the piston sealing ring is pushed to a sewage outlet of the toilet stool, the sealing ring rubs with the inner wall of the sewage outlet in contact to form a brake, and the piston stops rotating.

Preferably, the sealing washer that has the braking effect is detachable sealing strip, installs at stool pot piston surface after the sealing strip bends into the round, and the sealing strip both ends are fixed at the piston and are moved down to the position of several centimetres apart from the drain, and the sealing strip can be followed the piston and is dismantled, also can change simultaneously.

Preferably, the sealing ring material with the braking function comprises an elastic material, is convenient to replace, and has the advantages of large friction coefficient, good flexibility, wear resistance and the like, such as rubber materials.

Various mechanical brake materials are not elastic. The brake of the invention is greatly different from brakes of various vehicles and mechanical equipment, the rotary power and the speed of the brake of the invention are relatively small, and mainly, the sealing ring which plays the role of a brake pad has the function of forming sealing with the inner wall of a sewage draining outlet.

The sealing ring slot hole is arranged around the piston, the elastic sealing ring is arranged, the sealing ring can be easily and directly arranged in the piston slot hole, the outer surface is exposed, and other fasteners are not needed. The sealing ring comprises a conical surface sealing ring and an O-shaped ring 7 on the circumferential outer surface.

Preferably, the largest outer diameter of the outer wall of each part of the piston body is smaller than the diameter of the sewage outlet of the toilet.

The sealing ring installed on the piston determines the highest position of the piston which is reached upwards, prevents the piston from upwards running out of the sewage draining exit, and keeps stable with the sewage draining exit of the toilet when the piston is supported and upwards positioned at the highest position.

The piston sealing ring is removed or installed, and a hand or a tool can be inserted from the sewage outlet of the toilet bowl for operation without moving the toilet bowl or the surrounding panel of the toilet bowl. The outer diameter of the piston body for removing the sealing ring is smaller than the diameter of the sewage outlet of the toilet, the piston body can penetrate through the sewage outlet of the toilet, when the sealing ring is removed from the piston body during product maintenance, the piston body is separated from the piston support, the piston can be taken out from the sewage outlet of the toilet and then installed from the sewage outlet,

after the piston is provided with the sealing ring, the outer diameter of the sealing ring is larger than the drain outlet of the toilet stool, and the sealing ring can prevent the mounted piston from penetrating through the drain outlet of the toilet stool and preventing the piston from reaching the space of a toilet bowl.
