Type, is respectively provided with gap between two straight flange sides of core print seat and the inwall of inner chamber, and the water under high pressure for entering from base passes through the two
Gap is entered in inner chamber, as first conical surface at core body top is matched with the side wall of the coned face of inner chamber, and showerhead hole is located
Space is closed by first conical surface, and water under high pressure can only be sprayed in blind hole by guiding gutter, as guiding gutter is for being crisscross arranged, penetrating
Water under high pressure high-speed rotation in the blind hole, forms water column, under the influence of centrifugal force, sprays from showerhead hole high speed, and empty around
There is strong friction in gas, current are torn to form tiny water smoke, and the water smoke of formation is one-level water mists, and more leaching effect is more preferable, uses
The water yield can be reduced, without dynamic component, it is possible to use the hydraulic pressure of higher pressure.
The core body is provided with four guiding gutters being crisscross arranged along blind hole periphery.The current being sparged in blind hole are easier
Rotation, improves its centrifugal effect.
The core print seat bottom is provided with yi word pattern intake chamber.Improve water inlet effect.
The outside of first conical surface is provided with second conical surface.Make vortex at this, is more readily formed, strengthen its turbulence intensity, have
It is beneficial to form water smoke.
The end of the base is in pentahedron, and each face is provided with a nozzle body.Bigger spread of spray is provided, is improved
Extinguishing effect.
It is an advantage of the invention that：High-Pressure Water can be in atomization in-core high-speed rotation, it is easier to tiny water smoke, more soaks effect
More preferably, water consumption is few, it is possible to use the hydraulic pressure of greater degree.
