DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiment I

(22) Referring to FIG. 1 to FIG. 17, a flushing method for a toilet is provided. The toilet comprises a toilet bowl 1, a toilet body 2 and a toilet bottom 3 integrally formed with the toilet bowl 1 and the toilet body 2, and a toilet bowl 1 is provided at the lower end thereof with a trap 4, wherein a sewage receiving area 6, which is inclined and is specially arranged for changing a sewage falling speed and direction, is provided on a side, corresponding to a sewage falling direction, of the upper end of a trap 4 and in an area with a certain height; a water sealing surface 44 of the trap 4 is located below the sewage receiving area 6, and a horizontal cross-sectional area 43 of the aperture of the top end of the trap 4 is slightly larger than the area of the water sealing surface 44; a water flushing port 7 is provided in the upper end of the sewage receiving area 6; a water storage cavity 5 is formed among the toilet body 2, the toilet bowl 1 and the toilet bottom 3; the water flushing port 7 is in communication with the water storage cavity 5; a first water valve 45 is arranged at an intake end of the water flushing port 7; the toilet is also provided with a control device for controlling the opening and closing of the first water valve 45 and controlling the opening size of the first water valve 45; in addition, the toilet is further provided with a water inlet system for injecting water into the water storage cavity 5; therefore, when small excrement is discharged, the first water valve 45 is opened slightly in front of the small excrement falling into the sewage receiving area 6 through the control device, so that the water storage cavity 5 flushes small-flow water into the sewage receiving area 6 through the water flushing port 7, and then the small excrement can slide into a water seal under the combined action of kinetic energy of the excrement, timely cooperation between small-flow flushing water flow blocking and flushing, and optimal guidance of the sewage receiving area 6 to the speed and direction of falling sewage, thereby preventing sewage splashing and odor emission; sewage traces left at the sewage receiving area 6 are also quickly flushed with small-flow flushing water, thereby preventing sewage attachment and odor emission; and when large excrement is discharged, the first water valve 45 is opened obviously in front of the large excrement falling into the sewage receiving area 6 through the control device, so that the water storage cavity 5 flushes large-flow water into the sewage receiving area 6 through the water flushing port 7, and then the large excrement can be discharged towards an outlet of the trap 4 under the combined action of kinetic energy of the excrement, timely cooperation between large-flow flushing water flow blocking and flushing, and optimal guidance of the sewage receiving area 6 to the speed and direction of falling sewage, so that sewage can be flushed away immediately with a small amount of flushing water, thereby saving on water and preventing sewage splashing and odor emission.

(23) One side of the bottom, corresponding to the bottom of a sewage sliding track, of the trap 4, including the sewage receiving area 6, is integrally in a streamlined design; and when sewage slides into the water seal along the sewage receiving area 6 and then is discharged to a water outlet in the tail end of the trap 4, the moving track is a smooth and streamlined moving track.

(24) The bottom of the toilet body 2 is attached to the ground, the toilet bottom 3 is flush with the bottom of the toilet body 2 or slightly higher than the bottom of the toilet body 2, and the trap 4 is generally located below the toilet bottom 3; therefore, the distance between the water flushing port 7 and the hip and the distance between the sewage receiving area 6 and the hip are large enough, the kinetic energy generated when sewage makes contact with the sewage receiving area 6 is larger, and sewage can be flushed away with a smaller amount of flushing water; and therefore, the effective volume of the water storage cavity 5 can be greatly increased.

(25) The first water valve 45 is composed of a circular ring 10 and a valve body 11, the outer circumferential surface of the circular ring 10 is connected with the inner circumferential surface of the water flushing port 7 in a sealed and embedded mode, the valve body 11 is rotatably hinged to the top of the circular ring 10, a rubber sheet 12 is arranged on the valve body 11, and when the free end of the valve body 11 rotates downwards until the rubber sheet 12 of the valve body 11 is attached to the top surface of the circular ring 10, the first water valve 45 is closed; a torsion spring 13 is connected between the valve body 11 and the circular ring 10, and the acting force of the torsion spring 13 tends to close the first water valve 45; the control device comprises a fixed pulley 14 arranged on the rear side wall of the toilet body 2 and a flexible steel wire 15 of which the lower end is connected with the free end of the valve body 11; the free end of the flexible steel wire 15 surrounds the fixed pulley 14 and extends out of the top of the right or left side wall of the toilet body 2 to the outer side of the toilet body 2; a pull ring 16 is arranged at the end part of the free end of the flexible steel wire 15; when the pull ring 16 is handheld and the free end of the valve body 11 is pulled to rotate upwards through the flexible steel wire 15 and the fixed pulley 14, the first water valve 45 is opened; and when the pull ring 16 is loosened, the free end of the valve body 11 rotates under the combined action of the self gravity of the valve body 11 and the torsion of the torsion spring 13 until the rubber sheet 12 of the valve body 11 is tightly attached to the top surface of the circular ring 10, and the first water valve 45 is closed.
