Spring is set on the sunpender between floating sprinkler and fixture nut.
Nozzle cap can be used to be fixed on water pond, and the uniformly distributed water sprinkler of coaxial arrangement is fastened on nozzle cap bottom by flanging
Portion, inlet channel extend into uniformly distributed water sprinkler inner cavity, and the shower water entered from water pond is flowed into uniformly distributed water sprinkler by inlet channel, and
It flows downward across bracket, a part of water flow is directly fallen by fin clearance, and another part water flow falls in floating sprinkler
On fin and it is knocked the water droplet broken, formation is splashed outward, so that uniform spraying effect is formed below spray head, due to floating
Dynamic sprinkler can move up and down under hydraulic pressure and spring force effect along sunpender, when hydraulic pressure is larger, under the impact of water flow,
Spring is compressed, and floating sprinkler is moved down along sunpender, and spacing increases between fin and uniformly distributed water sprinkler, the water flow fortune of whereabouts
It is dynamic apart from longer, and more water flows be vertical direction toward impact after fin to upper rebound, the water droplet to splash around is reduced, to guarantee
Spray area hydraulic pressure increase when remain unchanged, when hydraulic pressure reduce when, spring force effect under, floating sprinkler along sunpender to
Upper movement reduces the spacing between fin and uniformly distributed water sprinkler, strikes water flow on fin and formed and more splashed around
Water droplet, can also hydraulic pressure decline when keep spray area it is constant, such spray head may be implemented to be ok under different hydraulic pressure
Uniform spray range is kept, to improve radiating efficiency.
The fin is arc-shaped flaky body.Parabola can be formed after flow impact to splash down, and improve the uniform of water flow distribution
Property.
Groove is equipped on the fin top surface.Water flow can form biggish downward pressure after hitting fin, and can
To obtain bigger splashing power, to guarantee to spread more evenly.
It is arc transition between the inlet channel and the flanging.The shower water in water pond is facilitated to fall.
Annular step portions are equipped in the flanging bottom, the flanging is fastened in stepped part.It can be with by stepped part
Fast fastening flanging facilitates connection.
The utility model has the advantages that: the height of water droplet splash can be adjusted according to variation in water pressure, guarantee spray area not
Become, to improve radiating efficiency.

Specific embodiment
Embodiment:
Refering to fig. 1-6, a kind of crossing current tower variable-flow spray head, including be equipped with the nozzle cap 1 of inlet channel 2, hollow circular it is equal
Cloth water sprinkler 3, axle center be equipped with sleeve 11 floating sprinkler 4, sunpender 5, spring 6 and fixture nut 7, wherein nozzle cap 1 and
Cloth water sprinkler 3 is coaxially disposed, and horizontal flanging 8 is equipped at the top of inlet channel 2, is arc transition between inlet channel 2 and flanging 8.
It is equipped with the flanging 9 for being fastened on 8 bottom of flanging at the top of uniformly distributed water sprinkler 3, wherein 8 bottom of flanging is equipped with annular step portions 14,
Flanging 9 is fastened in stepped part 14.It is equipped with bracket 10 in uniformly distributed 3 bottom of water sprinkler, the top of sunpender 5 is connected to the axis of bracket 10
At the heart, the sleeve 11 of floating sprinkler 4 is set in outside sunpender 5, and sleeve 11 is externally provided with the fin 12 of several plates, fixed spiral shell
Mother 7 is arranged on the bottom end of sunpender 5, and spring 6 is set on the sunpender 5 between floating sprinkler 4 and fixture nut 7.Fin 12
For arc-shaped flaky body, groove 13 is equipped on 12 top surface of fin.In the present embodiment, bracket 10 is three-chip type structure, in this way can be with
It can guarantee enough water stream channels while guaranteeing enough structural strengths.
Nozzle cap 1 can be used to be fixed on water pond, and the uniformly distributed water sprinkler 3 of coaxial arrangement is fastened on spray head by flanging 9
1 bottom of lid, inlet channel 2 extend into uniformly distributed 3 inner cavity of water sprinkler, and the shower water entered from water pond is uniformly spilt by the inflow of inlet channel 2
It in hydrophone 3, and passes through bracket 10 and flows downward, a part of water flow is directly fallen by 12 gap of fin, and another part water flow is fallen
On the fin 12 of floating sprinkler 4 and it is knocked the water droplet broken, formation is splashed outward, to be formed below spray head uniform
Spraying effect, since floating sprinkler 4 can move up and down under hydraulic pressure and the effect of 6 elastic force of spring along sunpender 5, when hydraulic pressure compared with
When big, under the impact of water flow, spring 6 is compressed, and floating sprinkler 4 is moved down along sunpender, fin 12 and uniformly distributed water sprinkler 3
Between spacing increase, the water flow movement of whereabouts apart from longer, and more water flows be vertical direction toward impact after fin 12 to upper rebound, subtract
Few water droplet to splash around, to guarantee that spray area is remained unchanged when hydraulic pressure increases, when hydraulic pressure reduces, in spring 6
Under elastic force effect, floating sprinkler 4 is moved up along sunpender 5, is reduced the spacing between fin 12 and uniformly distributed water sprinkler 3, is hit
