Specifically, the flushing device <NUM> comprises the device main body <NUM>, the flushing nozzle <NUM> and the flushing spray head <NUM>.

The device main body <NUM> has a mounting cavity <NUM>, the top of the mounting cavity <NUM> is open. The flushing nozzle <NUM> is mounted in the mounting cavity <NUM>. The flushing spray head <NUM> is connected with the device main body <NUM> and the flushing spray head <NUM> is located on the outside of and in front of the mounting cavity <NUM>. The spray head <NUM> is arranged below the pipe body <NUM> and facing downwards. After the pipe body <NUM> is driven and extended out, the spray head <NUM> sprays water downward to flush the cavity wall of the toilet cavity <NUM> of the toilet main body <NUM> with a large flushing range.

Preferably, in the direction of the width of the toilet main body <NUM>, the spray head <NUM> is located in the middle of the toilet cavity <NUM>.

The spray holes can be set in different directions on the spray head <NUM> as needed to spray water around to increase the range of flushing and cleaning.

It should be noted that: the control water valve <NUM> has a plurality of outlets independent of each other, each outlet can be controlled by a separate valve, the water spray of the spray holes <NUM> and the spray head <NUM> are controlled independently of each other. All the water supply hoses <NUM> can be threaded into the mounting channel <NUM> to connect with the corresponding inlets of the spray hole water supply channel <NUM> and the spray head water supply channel <NUM>.

Thus, for the spray pipe assembly of the application, the flushing device <NUM> is integrated with the flushing nozzle <NUM> and the flushing spray head <NUM>, so that the water pipes can all be arranged in the pipe body <NUM>, which saves installation space, reduces the volume, simplifies the structure, and facilitates installation.

In this embodiment, the first water supply channel <NUM> is located in a lower position, the height of the nozzle water cavity <NUM> can be properly increased, and the volume of the nozzle water cavity <NUM> can be increased, so water is subjected to a buffering and pressure reducing effect after entering the nozzle water cavity <NUM>, thereby avoiding high-pressure water from directly rushing out of the front spray hole <NUM>. And the rear spray hole <NUM> needs a slightly higher water pressure, so the second water supply channel <NUM> can be arranged in a higher position, which can shorten the length of the nozzle water channel <NUM> and is beneficial for water to quickly spray out from the rear spray hole <NUM>.

In one of the embodiments, as shown in <FIG> and <FIG>, the spray hole water supply channel <NUM> and the spray head water supply channel <NUM> are respectively channel grooves provided on the circumferential surface of the flushing nozzle <NUM>.
