液体排放装置，特别可用作植物抗病毒接种的便携式接种枪
Liquid discharge apparatus particularly useful as a portable inoculation gun for anti-virus inoculation of plants
US-7406981-B2用于植物接种，便携式液体喷射。
专利摘要
液体排放装置，特别可用作植物抗病毒接种的便携式接种枪，包括壳体，其一端具有配置为便于用户抓握的手柄，相对端具有用于从其排放口排放液体的喷嘴，以及可手动操作以从喷嘴产生液体排放的可操纵构件。喷嘴包括与排放口连通的气体通道和与气体通道连通的液体通道。气体输送系统可由可操纵构件致动以通过气体通道经由排放口高速排放气体。液体源与喷嘴中的液体通道连通，使得每次通过气体通道从喷嘴高速排放气体时，将一定量的液体从液体源吸入气体通道并随气体通过排放口高速排放。
Original abstractLiquid discharge apparatus, particularly useful as a portable inoculation gun for anti-virus inoculation of plants, includes a housing having a handle at one end configured for convenient grasping by a user, a nozzle at the opposite end for discharging liquid from a discharge opening therein, and a maniputable member manually actuatable to produce a discharge of liquid from the nozzle. The nozzle includes a gas passageway communicating with the discharge opening, and a liquid passageway communicating with the gas passageway. A gas delivery system is actuatable by the maniputable member to discharge gas at high-velocity through the discharge opening via the gas passageway. A liquid source communicates with the liquid passageway in the nozzle such that each high-velocity discharge of gas from the nozzle via the gas passageway draws a quantity of liquid from the liquid source into the gas passageway and discharges it at high-velocity with the gas through the discharge opening.
