Abstract:
1. A liquid dilution device, comprising: a main body; a diluent passage formed in said main body; a negative pressure generate section formed in some midstream of said diluent passage; a first connect passage formed in said main body and connected to said negative pressure generate section; a special liquid supply passage to supply special liquid to said diluent passage through said first connect passage; a rinse liquid supply passage formed in said main body being different from said diluent passage; a negative pressure generate section formed in some midstream of said rinse liquid supply passage; a cylindrical dial disposed to be free to pivot outside said main body; a plurality of jets disposed on a specific circumference of said dial to connect said first connect passage to said special liquid supply passage; an outer body disposed outside said dial to cover said jet; an outer connect passage formed at the facing position of said dial and said outer body, to be connected with the other jet than the jet which connects said first connect passage to said special liquid supply passage; a rinse liquid introduce passage connected at one side to a position which negative pressure is smaller than that of said negative pressure generate section of said rinse liquid supply passage, and connected at the other side to said outer connect passage; an inner connect passage formed at the facing position of said dial and said main body, to be connected with the other jet; and a second connect passage connected at one side to said inner connect passage, and at the other side to said negative pressure generate section of said rinse liquid supply passage; wherein negative pressure is generated at said negative pressure generate section of said rinse liquid supply passage by flowing liquid in said rinse liquid supply passage, and the liquid is conveyed by the negative pressure from said rinse liquid supply passage to said negative pressure generate section of said rinse liquid supply passage in order via said rinse liquid introduce passage, said outer connect passage, the other jet, and said second connect passage, so that the liquid flowing in said rinse liquid supply passage flows through the other jet.
