| 摘要 |
The present invention relates to a device for widely spraying drugs and, specifically, to a device for widely spraying drugs, which comprises: a drug container for storing liquid drugs inside; a driving motor; a pump driven by being connected to the driving motor; a spraying means equipped with a nozzle for spraying the drugs pressurized by the pump; and a ventilation means for supplying air for spraying in a spray direction around the spray nozzle. The device for spraying is constituted to be driven with a single engine of a cylinder pump for generating high pressures, a centrifugal pump for generating low pressures, and a ventilation fan for generating air pressures, thereby evenly spraying in a wide range at the same time, by performing high pressures and low pressures at the same time, spraying in a remote distance with the high pressures, and spraying in a short distance with the low pressures. |
