Sprayer
First Claim
1. A spray comprising a first storage part and a second storage part for storing a spray liquid, a spray part spraying the spray liquid stored in said second storage part, a feeding part feeding a constant quantity of spray liquid from said first storage part to said second storage part, a liquid sensing part detecting presence/absence or increase/decrease of the spray liquid in said second storage part and a feeding determination part for determining whether or not said second storage part requires feeding on the basis of an output from said liquid sensing part, for automatically adjusting the quantity of spraying by adjusting power supplied to the spray part so that the spray liquid is fed to said second storage part at a prescribed interval.

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.
