Abstract
A spray sprays a liquid medicine from a spray part . When a liquid sensing electrode arranged on the spray part senses the quantity of the liquid stored in a storage part and determines that the quantity of the liquid decreases, a pin part is driven by a solenoid for feeding the liquid medicine from a liquid medicine bottle to the storage part of the spray part through a feed pipe , and the feeding interval is obtained when the liquid medicine is intermittently fed for adjusting power supplied to a piezoelectric element of the spray part so that the feeding interval is constant. Consequently, a spray capable of automatically adjusting the quantity of spraying per unit time to a constant level for spray liquids having various properties can be provided.
