Abstract
A nozzle unit of a liquid spray apparatus is constituted by a conduit tube having an outer portion spreading and curvature shape upper inner wall, a disc shape flat plate cover arranged on an upper portion of the conduit, and a coupling. Between the flat plate cover and the conduit tube a spray port of the nozzle unit is formed. From the spray port of the liquid spray apparatus, a thin film liquid (a thin film spray body) is sprayed. To this thin film liquid a swirl component (a squint direction component) is given and run down, to the thin film liquid a liquid pressure fluctuation generates, the pulsation movement is given to the thin film liquid. In a case where a nozzle unit has a ring shape spray port a melon shape spherical thin film spray body is formed and in a case where a nozzle unit has a linear shape spray port a circular shape thin film spray body is formed. The liquid spray apparatus in which a thin film spray body can reach to a desirable run down point without the scattering of the liquid droplets and without the film cut off according to the pulsation can be obtained.
