23


. The tubular bodies


30


and


31


of the inner side of the face plate


23


, and the locating walls


331


,


341


and


351


are in intimate contact with the outer side of the water distribution disk


40


. The through hole


46


of the water distribution disk


40


, the guide slot


461


, and the locating hole


43


are in communication with the tubular bodies


30


and


31


. The guide hole


501


of the first arcuate body


50

53


which are circularly arranged and are corresponding in location to the ribs


22


of the water emission cover


20


. The round holes


53


are in communication with the guide hole


522


of the water distribution disk


40


by the annular slot


54


of the water distribution disk


40


. The water distribution disk

is fastened with the water emission cover


20


by the high frequency wave process.




As shown in FIGS.


8


and


8


-


1


, a water flow


1


is guided into the guide hole


522


via the through hole


461


of the water distribution disk


40


. The water flow


1


is further guided into the full flow hole


24


of the water emission cover


20


via the annular slot


54


of the water distribution disk


40


and the round holes


53


of the annular side


41


of the water distribution disk


40


. In light of the water distribution disk


40


being fastened with the water emission cover


20


by the high frequency wave process, the water flow


1


can not flow in reverse into the interior of the head seat


11


, thereby allowing the water flow


1


to be emitted from the full flow hole


24


. In light of the round holes


53


being aligned with the ribs


22


of the water emission cover


20


, the water flow
