Patent attributes
A fluid spraying device comprises a first supply flow path which guides a pressurized liquid, a second supply flow path which guides a pressurized gas, a gas-liquid mixing part which joins the first supply flow path and the second supply flow path and which mixes the liquid and the gas, and an ejection flow path which guides a fluid from the gas-liquid mixing part to the outside. A branching/joining part is provided at an intermediate part of the ejection flow path which, after branching the ejection flow path into a plurality of branch flow paths, rejoins these branch flow paths together. Moreover, a fluid spraying nozzle comprises a flexible spray tube, and a guide which surrounds the spray tube from the outside in the diametral direction. A ring-shaped tube side-magnet is provided on the spray tube, a ring-shaped guide side magnet is provided on the guide, and the polarity of the outer peripheral side of the tube side magnet and the polarity of the inner peripheral side of the guide side magnet have the same polarity.
