Swivel head 1, is rotatably connected on stator, with fluid cavity and at least one fluid being connected to fluid cavity
Entrance 11 and several fluid outlets 12；
Nozzle 3 is several, and the corresponding fluid outlet 12 of each nozzle is mounted on swivel head 1, axis and rotation
The axis of first 1 short transverse is tilted a certain angle；Several nozzles 3 are formed at least two layers along the short transverse of swivel head 1,
The axis of adjacent two layers nozzle 3 is different from the angle a that the axis of the short transverse of swivel head 1 is formed；
Power jet 4, at least one, corresponding fluid outlet 12 are arranged on swivel head 1, axis and swivel head 1
The axis of short transverse is vertical, for the effect by the fluid in fluid cavity, drives the rotation of 1 relative stator of swivel head
Turn.
The multi-arm type auto-rotating spray head of above structure, since several nozzles 3 are formed along the short transverse of swivel head 1
At least two layers, and the axis of adjacent two layers nozzle 3 is different from the angle a that the axis of the short transverse of swivel head 1 is formed, so that position
It is in interlaced mode in the direction that the nozzle 3 of different layers sprays solution, nozzle 3 carries out the external world from multiple angles comprehensive
Atomized soln is sprayed, there is no sprinkling blind areas；Meanwhile multiple power jets 4 can generate bigger active force simultaneously and carry out band
Dynamic swivel head 1 does high-speed motion, improves the atomizing effect of nozzle 3, and increase nebulization region.
As variant embodiment, in several above-mentioned nozzles 3, the axis of portion nozzle 3 and the height side of swivel head 1
To axis be overlapped, and the axis of another part nozzle 3 and the axis of the short transverse of swivel head 1 are tilted a certain angle so that
Cross one another arrangement mode is integrally formed in several nozzles 3 on swivel head 1, and the nozzle 3 on adjacent layer sprays the side of solution
It doubles to staggered, the solution for further ensuring that nozzle 3 sprays can cover the external world in all directions, blind there is no spraying
Area.
For different for the angle a that the axis of adjacent two layers nozzle 3 is formed from the axis of the short transverse of swivel head 1,
Such as the angle of the angle a of the axis formation of the short transverse of the axis of one layer of nozzle 3 and swivel head 1 is 32 degree, it is adjacent thereto
Another layer of nozzle 3 axis and swivel head 1 short transverse axis formed angle a angle be 50 degree.Or its
He spends, depending on actual use situation angle as long as the angle of adjacent two layers is inconsistent as specific setting is how many.
As the variant embodiment of power jet 4, the axis of the short transverse of the axis and swivel head 1 of power jet 4
It is tilted a certain angle, such as 80 degree, 70 degree, 60 degree of inclination etc., but inclined angle is unsuitable too low, otherwise power jet 4 drives
The torque relative reduction that swivel head 1 rotates, it is general to be not less than 60 degree, that is, inclined angle is closer to 90 degree, power jet 4
The torque for driving swivel head 1 to rotate is bigger, and the speed that swivel head 1 rotates is faster, and atomizing effect is more preferable.
In addition, can be 1,2,3,4,5,6 and 6 or more for the number that power jet 4 is arranged
Deng it is further preferable that several power jets 4 are arranged on swivel head 1 in symmetric mode；It can not also be in pair as deformation
Title mode is arranged on swivel head 1, as long as can play the role of that swivel head 1 is driven to rotate.
As shown in figure 3, several layers installing zone 13 is formed on the outer wall of swivel head 1 as preferred embodiment, it is several
Layer installing zone 13 is distributed along the short transverse of swivel head 1, and the outer diameter of adjacent two layers installing zone 13 is different；
Several mounting holes 14, the axis of the short transverse of the axis and swivel head 1 of mounting hole 14 are set on installing zone 13
It is tilted a certain angle, several mounting holes 14 are arranged in a one-to-one correspondence with fluid outlet 12；
Several nozzles 3 are mounted on swivel head 1 by mounting hole 14.
The multi-arm type auto-rotating spray head of this structure forms several layers installing zone 13 on the outer wall of swivel head 1, and if
The mounting hole 14 that angle needed for tilting is opened up on dried layer installing zone 13, nozzle 3 is mounted in mounting hole 14, adjacent two layers are pacified
The outer diameter in dress area 13 is designed to difference, forms the installing zone 13 being staggered, can be to avoid opening up on adjacent two layers installing zone 13
The phenomenon that being punched when required mounting hole 14, if because directly opening up mounting hole on the outer wall of swivel head 1 in the prior art
When 14, the tilt angle of the mounting hole 14 of adjacent layer is inconsistent, needs the wall thickness by swivel head 1 to do sufficiently thick, can make
It obtains and is not punched between the mounting hole of adjacent layer, be not easy to installation nozzle；To which the setting of installing zone 13 also mitigates swivel head 1
Weight and reduce the wall thickness of swivel head 1, nozzle 3 is installed convenient for there is bigger space；Meanwhile the installing zone of various outer diameter
13, the protruding distance gone in the end of nozzle 3 mounted thereto can be made to be not quite similar, the distance that each nozzle 3 sprays
It has differences, the direction for spraying solution is easier staggeredly to further strengthen the comprehensive property of spray head injection.
In addition, it should be noted that, the outer diameter of the installing zone 13 of several layers can not be put down in the short transverse of swivel head 1
Together, unless the outer diameter of installing zone 13 do it is sufficiently large when, inclination different angle can be opened up on the installing zone 13 of adjacent layer
Mounting hole 14, otherwise mounting hole 14, which is also easy to appear, punches phenomenon, it is difficult to nozzle 3 is fixedly mounted in mounting hole 14,
When nozzle 3 is rotated as swivel head 1 does height, nozzle 3 is easy to fall off, and installation is also inconvenient, and also results in swivel head 1
The weight of installing zone 13 is big on outer wall, swivel head 1 rotation need torque it is big, the corresponding setting of power jet 4 it is enough, this
The volume and weight that sample will lead to spray head is too big, at high cost, manufacture less easy to process.
As further preferred, nozzle 3 and power jet 4 are all made of and are threadably received in mounting hole 14.
As the deformation of mounting hole 14, the angle of the axis formation of the short transverse of the axis and swivel head 1 corresponding to nozzle 3
The axis of above-mentioned part mounting hole 14, can also be overlapped by degree with the axis of the short transverse of swivel head 1.
As further preferred embodiment, there are multiple nozzles 3 on the installing zone 13 of same layer, increases the unit time
Interior 13 top nozzle 3 of same layer installing zone sprays the amount of solution, the axis for the multiple nozzles 3 on installing zone 13 being located on the same floor with
The angle for the angle a that the axis of the short transverse of swivel head 1 is formed is identical, and is evenly distributed on the circumference of swivel head 1, so that
The atomized soln that multiple nozzles 3 on the installing zone 13 of same layer spray is more evenly.For example, being arranged 8 on same layer installing zone 13
The angle for the angle that the axis of the short transverse of a nozzle 3, each nozzle 3 and swivel head 1 is formed is 45 degree, and 8 nozzles 3
Respectively on the circumference eight equal parts point of swivel head 1.It is further preferred that being installed when the number of nozzle 3 is even number in same layer
Several nozzles in area 13 are symmetric in the same plane.
It, can also be by the height side of the axis of multiple nozzles 3 on the installing zone 13 of same layer and swivel head 1 as deformation
To axis formed angle a angle it is not identical.
As further preferred embodiment, nozzle 3 is set at least two layers of installing zone 13, along the height of swivel head 1
Direction is spent, the angle that the axis of nozzle 3 forms angle with the axis of swivel head 1 is gradually reduced from the bottom of swivel head 1 to top,
So that more having levels of being distributed of the nozzle 3 on swivel head 1, longitudinal cross-section forms a fan-shaped arrangement, and the solution that nozzle 3 sprays exists
In all directions more evenly, it is also convenient for forming the installing zone 13 of multilayer on 1 outer wall of swivel head, nozzle 3 is mounted on swivel head 1
On.For example, the angle of angle gradually decreases to 0 degree from 90 degree.
As further preferred embodiment, power jet 4 is located on the installing zone 13 of the bottom, power jet 4
The axis of the short transverse of axis and swivel head 1 forms 90 degree of angles.Power jet 4 is located on the installing zone 13 of the bottom, just
Entire swivel head 1 is able to drive in power jet 4 to be rotated.
As deformation, power jet 4 can also be mounted on the installing zone 13 of other layers, such as positioned at 1 middle part of swivel head
Installing zone 13 on, on same installing zone 13 power jet 4 can also not only be arranged but also nozzle 3 or one layer is arranged is power
