The embodiment of the utility model also provides a toilet, wherein the toilet 1 comprises a toilet main unit 12, a toilet cover plate and the flushing system in the embodiment; the injection nozzle 50 is provided at an end of the injection pipe 122, the brush nozzle 123 is provided at an end of the brush pipe 121, and the injection nozzle 50 and the brush nozzle 123 are respectively attached to the injection port and the brush port of the ceramic body 13. The arrangement of the flushing system and the specific arrangement of the pipes in the toilet bowl 1 are shown in fig. 11 to 13.

The embodiment of the utility model provides a toilet bowl and a flushing system thereof, wherein the flushing system comprises a combined valve, a control device, a flushing pipeline and an injection pipeline, and the combined valve comprises a water inlet, a first water outlet, a second water outlet, a third water outlet, a first electromagnetic valve, a second electromagnetic valve and a third electromagnetic valve; the combined valve is used for respectively controlling water inflow of a washing pipeline and an injection pipeline which are arranged in the toilet; the water inlet of the combination valve is communicated with the water inlet pipeline; the first water outlet is connected with a first injection pipeline of the injection pipeline, the second water outlet is connected with a second injection pipeline of the injection pipeline, and the third water outlet is communicated with the washing pipeline. According to the flushing system, the combination valve and the control device are integrated, the control device controls the combination valve to control water inflow of the flushing pipeline and the injection pipeline, so that the use requirement of flushing control of a plurality of pipelines in the toilet is met, and the whole occupied volume of the flushing system is reduced.

While the utility model has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
