ABSTRACT:
A diluent passage12to introduce special liquid and a rinse liquid supply passage13which is separate from the diluent passage12are formed in the main body10, and a plurality of jets are disposed at a cylindrical dial18. A water convey passage is formed to connect two positions at the rinse liquid supply passage13where pressure difference occurs therebetween to the other jets19b,19cexcept the jet19athrough which the special liquid is introduced. When water flows in the rinse liquid supply passage13, the water is introduced to the water convey passage due to the pressure difference of the rinse liquid supply passage13. The water rinses the other jets19b,19cexcept for the jet19athrough which the special liquid is introduced. Therefore, adjusting changes or choking of the jets19b,19cwhich have not been used for a considerable time can be prevented.
