At present, the generation type of thin water smoke is generally rotary and collision type in the common fine mist spray head.Rotating sprinkler comprises interconnective base, nozzle body, and water under high pressure is entered by base, rotates in nozzle, strengthen its turbulence intensity, by the tiny spray orifice ejection on the nozzle body, reach atomizing effect again, but the hydraulic pressure of this shower nozzle is not high usually, and atomizing effect is bad, and water consumption is bigger; The collision type shower nozzle comprises that inside is provided with the nozzle of striker, by collision the current in the nozzle is smashed, and forms atomizing effect, but such mode can cause the wearing and tearing of equipment, and the water smoke skewness of generation spreads insufficiently, and atomizing effect is also limited.
Summary of the invention
The purpose of this utility model provides the better novel centrifugal type fine mist spray head of a kind of atomizing effect.
Technical solution of the present utility model is: a kind of novel centrifugal type fine mist spray head, comprise base and the nozzle body that is provided with the shower nozzle hole that is arranged on the base, described nozzle body inside is provided with the hollow cylindrical inner chamber, and interior top of chamber is a coned face, described shower nozzle hole is arranged on the place, summit of this coned face, in inner chamber, be provided with the atomizing core of forming by core print seat and core body, core print seat is runway shape and is connected with thread in inner cavity, core body is arranged on the core print seat and is cylindrical, the core body top is provided with blind hole, core body end face along the blind hole periphery is provided with first conical surface and at least two guiding gutters that are crisscross arranged along the blind hole periphery that match with the coned face sidewall of inner chamber, one end of guiding gutter communicates with blind hole, and the other end communicates with inner chamber.
Be provided with the atomizing core in the cylindrical cavity in the nozzle body, the core print seat of this atomizing core is runway shape, core body is cylinder type, has the gap respectively between two the straight flange sides of core print seat and the inwall of inner chamber, the water under high pressure that enters from base enters the inner chamber by these two gaps, because first conical surface at core body top matches with the sidewall of the coned face of inner chamber, space, place, shower nozzle hole is sealed by first conical surface, and water under high pressure can only spray in the blind hole by guiding gutter, because guiding gutter is for being crisscross arranged, the water under high pressure that sprays into is rotation at a high speed in blind hole, forms water column, under action of centrifugal force, spray from shower nozzle hole high speed, with surrounding air generation strong friction, current are torn and form tiny water smoke, and the water smoke of formation is the thin water smoke of one-level, more soak better effects if, water consumption can reduce, and does not have dynamic component, can use the more hydraulic pressure of high pressure.
Described core body is provided with four guiding gutters that are crisscross arranged along the blind hole periphery.Make the easier rotation of current that sprays in the blind hole, improve its centrifugal effect.
Described core print seat bottom is provided with the yi word pattern intake chamber.Improve the water inlet effect.
The outside of described first conical surface is provided with second conical surface.Make the easier formation vortex in this place, strengthen its turbulence intensity, help forming water smoke.
The end of described base is pentahedron, and each face is provided with a nozzle body.Bigger spread of spray is provided, improves the fire extinguishing effect.
The utility model has the advantages that: High-Pressure Water can rotate at a high speed at the atomizing in-core, and easier tiny water smoke more soaks better effects if, and water consumption is few, can use more high-grade hydraulic pressure.

The specific embodiment
Embodiment:
Consult Fig. 1-8, a kind of novel centrifugal type fine mist spray head comprises that the end is pentahedral base 1, is arranged on the nozzle body that is provided with shower nozzle hole 62 on the base 1 and is arranged on atomizing core 3 in the nozzle body 2.Wherein each face of base 1 is provided with 5, five nozzle bodies 2 of installing hole respectively by being threaded in the installing hole 5.Be respectively equipped with five inlet openings 4 in the base 1, be communicated with five installing holes 5 respectively, water under high pressure can be imported respectively in the installing hole 5.The inside of nozzle body 2 is provided with hollow cylindrical inner chamber 7, and the top of inner chamber 7 is a coned face 8, shower nozzle hole 6 is arranged on the place, summit of this coned face 8, atomizing core 3 is made up of core print seat 9 and core body 10, core print seat 9 be runway shape and with inner chamber 7 by being threaded, core body 10 is arranged on the core print seat 9 and is cylindrical, core body 10 tops are provided with blind hole 11, end face along the core body 9 of blind hole 11 peripheries is provided with first conical surface 12 that matches with coned face 8 sidewalls of inner chamber 7, first conical surface, 12 outsides are provided with second conical surface 14, and wherein the inclination angle of second conical surface 14 is greater than the inclination angle of first conical surface 12.Periphery along blind hole 11 is staggeredly equipped with four guiding gutters 13, and an end of guiding gutter 13 communicates with blind hole 11, and the other end communicates with inner chamber 7.Core print seat 9 bottoms are provided with yi word pattern intake chamber 15, and intake chamber 15 two ends lay respectively on two straight sided of core print seat 9.
Atomizing core 3 is threaded in the nozzle body 2 by core print seat 9, and nozzle body 2 is by being threaded in the installing hole 5, and base 1 bottom is by the external high-pressure water pipe that is threaded, and whole shower nozzle is by the installation that is threaded, easy construction.
During use, water under high pressure enters in the base 1, enter in the nozzle body 2 by inlet opening 4, because core print seat 9 is a runway shape, and inner chamber 7 is circular, form two gaps respectively between two straight sided of core print seat 9 and inner chamber 7 inwalls, water under high pressure can import two gaps by the yi word pattern intake chamber 15 of core print seat 9 bottoms and enter in the inner chamber 7, and is looped around around the core body 10.Because core body 10 end faces are provided with first conical surface 12 that cooperates with coned face 8 sidewalls at inner chamber 7 tops, the sidewall of first conical surface 12 and coned face 8 completely cuts off into two parts with inner chamber 8 upper spaces after fitting, and the water under high pressure in the inner chamber 8 can only spray in the blind hole 11 by guiding gutter 13.Because guiding gutter 13 is crisscross arranged along blind hole 11 peripheral intervals, after water under high pressure sprays in the blind hole 11, meeting contacts the inwall of blind hole 11 earlier and flows along blind hole 11 inwalls, a plurality of guiding gutters 13 import water under high pressure respectively, current rotation in the blind hole 11 is quickened, formed the water column of rotation at a high speed, under centrifugal action, ejection is torn into tiny water smoke by air from shower nozzle hole 6.The turbulence intensity that the second bigger conical surface 14 of inclination angle can improve the current that enter guiding gutter 13 places is set, more helps forming atomizing.Owing to there is not dynamic component, can use the more hydraulic pressure of high pressure grade, the water smoke of formation is given tiny, more soaks better effects if, and water consumption is corresponding can save, also corresponding the reducing of water stain infringement degree that the fire extinguishing back forms.
Above-listed detailed description is specifying at one of the utility model possible embodiments, this embodiment is not in order to limit claim of the present utility model, allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.
