Described fitted cover 11 is set in the outside of described cup 1 and described air motor；Described first end is near one end away from described cup 1 of described rotor 3；Axial line distance between described second end place plane and described rotor 3 end face is relatively large in diameter the axial line distance between the end face of one end and described rotor 3 end face less than described cup 1.
When practical application, the first end of fitted cover 11 and air motor are threadably secured away from cup 1 one end and are connected；Connection described herein is interpreted broadly, it is possible to be joined directly together, it is also possible to be indirectly connected to by intermediary.
When practical application, the outer wall of fitted cover 11 is made of metal, it is ensured that the intensity of fitted cover 11, and the inwall of fitted cover 11 is made of plastics, this is because plastic insulation.Operationally, the path of paint process to pass into high-tension electricity, for the safety of nebulizer, it is necessary to accomplish insulation.
Pressure-air enters in fitted cover 11 from air inlet, then pass through spray-hole 12 to spray, multiple equally spaced strip through holes make the pressure-air ejected form the air flow pattern of a Guan Bi, form an air knife, further ensure that atomization paint can spray in one direction accurately, rather than injection at random, improve the utilization rate of paint and the accuracy of injection direction.
The length-width ratio of described strip through hole is 1.01:1～100:1, it is preferred that the length-width ratio of strip through hole is 10:1 and 20:1.The thickness in the second end face axial direction is 3mm～35mm.
Described second end face there iing multiple spray-hole 12 along two different-diameters are provided circumferentially about；Vertical with the diameter of described fitted cover 11 and with described fitted cover 11 the central axis angle of the central axis of the described spray-hole 12 on one circumference is acute angle, and the pressure-air ejected is in line.
Vertical with the diameter of described fitted cover 11 and with described fitted cover 11 the centerline axis parallel of described spray-hole 12 central axis on another circumference is arranged；Better being controlled within it by the paint after atomization, the pressure-air ejected becomes contorted.
The air flow pattern of the Guan Bi that the spray-hole 12 that two rows are crisscross arranged is formed can be good at the injection direction of the paint after controlling atomization.
The inwall of fitted cover 11 has two cleaning through holes 24 along described fitted cover 11 axis direction.One of them cleans through hole 24 and is used to by air, and another cleans through hole 24 and is used for by solvent.When nebulizer works, two are cleaned through hole 24 all the time by air and solvent, and many cups 1 are carried out.
Also include columned capillary block 18, described capillary block 18 is provided with along its axis direction, and runs through the pore 19 of described capillary block 18；
The end face that described diverter 22 is relatively large in diameter be provided centrally with the ladder hole along its axis direction, described ladder hole includes the first hole 21 and the second hole 2 being sequentially connected with, and the diameter in described first hole 21 is less than the diameter in the second hole 2；Described first hole 21 is arranged away from described cup 1.
Described capillary block 18 is fixedly installed in described second hole 2, and described capillary block 18 leaves gap near one end and described second hole 2 in the first hole 21 between the end face in the first hole 21；Described pore 19 is just to described second hole 2 end face near the first hole 21.
When practical application, the diameter of pore 19 is set to 0.01～0.5 millimeter.Multiple pore 19 spaced sets.Pore 19, in order to penetrate solvent, is beneficial to atomising head inwall cleaning and reduces the liquid adhesive probability at deflector.
Described cup 1 close opening is provided with multiple groove connected by described cup 1 medial surface with end face on the medial surface of the bigger one end of round platform sectional area.The groove of multiple spaced sets forms multiple passage, and the paint after atomization passes in passage.Owing to passage is spaced set, make what the paint after atomization divided equally to eject from cup 1.
The specific works mode of above-mentioned two embodiment is: the rotation of cup 1 drives by air motor.Pass sequentially through spiral coil and ejector 13 from paint feeding mechanism paint out, be sent in cup head.High-tension bus-bar is led in the paint in capstan pipe.When, after liquid ejection end 16 ejection that paint is less from ejector 13 diameter, the centrifugal force that the cup 1 of high speed rotating produces makes coating particles form atomization, and then sprays from atomization spray orifice 20.
Pressure-air is entered by pressure-air feedway from the air inlet of fitted cover 11, sprays from spray-hole 12.Owing to spray-hole 12 is strip hole, the pressure-air ejected from multiple continuous print strip spray-holes 12 forms a high pressure gas wall closed, similar air knife, and this gas wall is compared with the high pressure gas wall of the pressure-air composition ejected from circular spray-hole, it is not easy to disperse, the molding effect of atomization paint is better.The so convenient paint spraying direction controlled after being atomized, paint is effectively utilized.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
