In order to seal the gap between the head main body 1 and the toilet jet port 411, the head main body 1 may be covered with a gasket 5 and pressed against the inner wall surface of the toilet bowl bottom by the stopper flange 17, as shown in fig. 4 and 5. Further, a gap between the head main body 1 and the toilet ejection port 411 may be sealed by potting.

According to the jet detection nozzle with the self-cleaning function, the detection cavity 14 is communicated with the toilet water seal, so that water in the toilet water seal and substances (including excrement, urine and the like) falling into the toilet water seal can partially enter the detection cavity 14 from the first opening 141, and therefore the detection sensor 2 can detect the water entering the detection cavity 14 and the substances contained in the water through the detection window 12 to obtain required detection data. When the toilet is started to flush, the water inlet channel 151 of the nozzle body 1 is filled with water and divided into two paths, one path of water is sprayed out through the spraying channel 152 and the nozzle to flush the dirt in the toilet water seal to the sewage discharge pipeline 42 of the toilet, the other path of water enters from the self-cleaning hole 13 and is accelerated through the self-cleaning hole 13 to flush the detection cavity 14 and the detection surface 121, the detection cavity 14 and the detection surface 121 are cleaned, and the cleaning water and the flushed dirt are discharged into the toilet water seal and are discharged into the sewage discharge pipeline 42 of the toilet along with the spraying water flow sprayed from the nozzle hole 11 of the nozzle body 1. Therefore, the invention can avoid the influence of residual dirt on the detection cavity 14 and the detection surface 121 on the accuracy of the detection data. The spray detection spray head disclosed by the invention not only has a spray detection function, but also realizes a self-cleaning function, so that the detection function is effective for a long time.

Referring to fig. 4 and 5, the toilet of the present invention includes a toilet seat 4, and further includes a jet detecting nozzle with a self-cleaning function as described above, wherein the nozzle body 1 is installed at a jet opening 411 at the bottom of a urinal 41 of the toilet seat 4.

The closestool can be a common closestool and also can be an intelligent closestool, and only the injection port 411 is needed to be arranged and the injection detection spray head can be installed.

The structure, structure and operation principle of the jet detection nozzle of the toilet bowl of the present invention are described in detail with reference to the foregoing description.

The spray detection spray head with the self-cleaning function and the closestool provided by the invention have the same or can be realized by adopting the prior art.

The above embodiments are only used to further illustrate the spray detecting nozzle and the toilet with self-cleaning function of the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention fall within the protection scope of the technical solution of the present invention.
