USPTO Abstract
A spray sprays a liquid medicine from a spray part 30. When a liquid sensing electrode 55, 56 arranged on the spray part 30 senses the quantity of the liquid stored in a storage part 30a and determines that the quantity of the liquid decreases, a pin part 27 is driven by a solenoid 26 for feeding the liquid medicine from a liquid medicine bottle 20 to the storage part 30a of the spray part 30 through a feed pipe 25, and the feeding interval is obtained when the liquid medicine is intermittently fed for adjusting power supplied to a piezoelectric element 50 of the spray part 30 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.
