Abstract
A liquid dilution device is provided to prevent choking at a jet for adjusting the flow amount of a special liquid. In the liquid dilution device in which the special liquid from a liquid supply passage 33 of a liquid intake device 29, is introduced to a diluent passage 12 formed in a main body 10 through a jet 22, an air intake opening 37 and a plug 38 to open and close the air intake opening 37 are provided at the liquid intake device 29 to connect the liquid supply passage 33 and atmospheric air. At the state that air from the air intake opening can be introduced to the diluent passage 12 through the jet 22 with the plug 38 opened, high velocity air passes through the jet 22 due to negative pressure generated at the diluent passage 12, by making water pass through the diluent passage 12. Due to the high velocity air, the special liquid stuck to the jet 22 is removed and the jet 22 is cleaned.
