PROBLEM TO BE SOLVED: To provide a pressure accumulation type liquid spray unit dispensed with classification waste dumping and having simplified structure having a small number of structure members. SOLUTION: The pressure accumulation type liquid spray unit is structured by the combination of a check valve 7 for opening a suction port 4a only at the time of sucking a liquid, a hollow stem 8 slidably covering the outside of a piston 5 while keeping the liquid tight and engaged with the end part of a piston guide 6, a pressing cap 9 adapted to the tip of the hollow stem 8 and having a nozzle 9a for spraying the liquid flowing out to the outside through a hollow stem space region M and a 1st elastic member 10 arranged between the pressing cap and a base member 3 each other and for keeping a passage 5 for the piston in a closed state by pressing the piston guide to the piston with the hollow stem, and a 2nd elastic member 11 formed integrally with the hollow stem and for pressing the piston to the piston guide and controlling the spray pressure of the liquid is disposed between the hollow stem and the piston and the whole structural members are made of the synthetic resin. |
