ELECTROSPRAYER Russian patent published in 2004 - IPC

FIELD: devices for production of monodisperse aerosols.

SUBSTANCE: the invention is pertinent to devices for production of monodisperse aerosol and may be used in agriculture, medicine, meteorology, food-processing industry, textile industry. The technical problem solved by the invention is to increase efficiency of spraying and to protect plants by the a sprayed preparation, to increase of speed of plants treatment, to eliminate a revolving moment at spraying the high plants, to decrease the weight of the electrosprayer and to improve conditions of its operation. To realize the task the device contains a high-speed engine with a jacket and a spraying organ located on its shaft - all installed on one end of the first spray boom; and also located on the first spray boom a container for the sprayed liquid supplied with a tube with a tip to connect it with a spraying organ; the second boom made telescopic with a fixing device joined with the first boom and capable for angular motion in respect to it. The first boom has a plug socket located on its other end and used for connection of the power supply. The plug socket electrically is fused to the electric motor and the power supply, according to the invention. The spraying organ is made in the form of a hollow truncated cone with its vertex facing the electric motor and restricted on the part of the vertex by a cylinder, the bottom of which is set on the jacket and has the axial coupling with the shaft of the engine. The lateral inside surface of cylinder is made extending to the bottom with the conicity, which does not exceed 0.01. The bottom of the cylinder has holes adjoining to its lateral surface. The tip with a diameter of d is fixed at the distance of afrom a bottom of the cylinder and spaced by b from an internal lateral surface of the cylinder. At that 0,1d <a <d, b > d, and the container for a liquid spraying is located in middle part of the first boom.

EFFECT: increased efficiency of spraying, protection of plants, speed of plants treatment, decreased the weight of the electrosprayer, improved conditions of its operation.
