Abstract
Abstract The liquid sprayer pipe made of a flexible material has liquid spraying slits inclined in an acute angle with respect to a wall of the liquid sprayer pipe. The slits are opened with vibrations by the pressure of a liquid which passes through the liquid sprayer pipe, whereby the liquid is sprayed in a wide range and in a long distance along the liquid sprayer pipe. In the case of a cylindrical pipe, the liquid spraying slits are formed along a tangent of an inner surface of the pipe.
