[0051] Working principle: (1) Clearing blockage: When blockage occurs in the toilet bowl 2 and the sewage pipe 3, the operator can put down the toilet lid 4 and close the upper port of the toilet bowl 2, so that a closed space can be formed inside the toilet bowl 2.

[0052] Then, remove the top cover 5, and by repeatedly pressing the manual hydraulic press 9 downward, the spring reset button drives the compressed air pump 10 to automatically reset, so that the air pump 10 can inflate and pressurize the internal space of the seat bucket 2. If necessary, a certain amount of water can be first put into the seat bucket 2 through the water tank 6, and then the internal space of the seat bucket 2 can be inflated and pressurized, while pressing the toilet cover 4 to prevent the toilet cover 4 from being lifted by the internal air pressure. The air pressure inside the seat bucket 2 gradually increases, and the blocked object is slowly pressed into the sewage pipe 3, and slowly discharged into the building drainage pipe through the sewage pipe 3 to clear the blocked part. In this process, there will be no situation where sewage splashes out and pollutes the bathroom environment when the handheld dredging tool is used for dredging, which is cleaner and more hygienic. At the same time, the manual air filling device built into the toilet will not take up additional space in the bathroom, and can also save the amount of water required for dredging by water pressure method.

[0053] (2) Neutralization and deodorization: During the process of clearing the blockage, the air pump 10 can simultaneously inhale the mixed gas containing the air freshener 1406 in the air freshener device 14 that escapes into the air. This mixed gas is pumped into the seat tub 2 through the air pump 10 for pressurization, and can also neutralize the odor in the seat tub 2 at the same time, thereby reducing the odor of the air after clearing the blockage.

[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
