Exhaust port 1h is set at upside, is set at downside into liquid interface 1i, in exhaust port 1h and the level-one runner 1a in main body 1
Between form the first water conservancy diversion runner 1e, in main body 1 between the lower end of liquid interface 1i and the vertical water conservancy diversion blind hole 1c into
The opening's edge that type has the second water conservancy diversion runner 1f, the two level runner 1b sets drainage inclined-plane 1s, if the bottom of two level runner 1b is set
Do stream aperture 1q.
Partition plate 3 is arranged at the oral area of two level runner 1b in main body 1, is set on partition plate 3 above the drainage inclined-plane 1s
Stream seam 3a.
4a represents the mounting hole on cover board 4 in Fig. 4, and the mounting hole 4a on cover board and the mounting hole in main body are passed through with screw rod
Connection, and O-ring seal is set in the engaging portion of cover board 4 and main body 1, cover board 4 is sealed to the oral area for being assemblied in level-one runner 1a.
During work, developer solution is inputted from into liquid interface 1i, is entered level-one runner 1a through the second water conservancy diversion runner 1f, is uniformly spread out
Uniformly it flow to the drainage inclined-plane of secondary streams road 1b opening's edges behind 3 surface of partition plate through the overcurrent seam 3a on partition plate 3 in level-one runner 1a
1s so that developer solution is flow in two level runner 1b along two level runner 1b side walls, and the developer solution in two level runner 1b is maintained at same
One liquid level, makes developer solution go out to flow aperture from two level runner 1b bottoms by developer solution in the two level runner 1b balanced static pressure formed
1q realizes the uniformity of spraying and low impact without impact or low impact outflow.Meanwhile inner flow passage gathers in nozzle spraying process
The gas of collection is finally flowed out through the first water conservancy diversion runner 1e from exhaust port 1h.
Further it is additionally provided with insulation liquid recycle stream road.The concrete structure for keeping the temperature liquid recycle stream road is as follows:The two of main body 1
A side is recessed respectively inwards to form two side channels 1n, 1r, and the oral area sealing of two side channels 1n, 1r are installed two side plates 2,5 and formed
Liquid accommodating cavity is kept the temperature, the left side of main body 1 sets two insulations interface 1g, 1j at left side and right side, protected in main body 1 at one
The 3rd water conservancy diversion runner 1d is formed between warm interface 1g and a side channel 1r, in another insulation interface 1j and another side channel 1n
Between form the 3rd water conservancy diversion runner 1k, the 5th water conservancy diversion runner for connecting described two side channel 1n, 1r is also formed in main body 1
1o.During work, two insulation interface 1g, 1j, mono- inlet tube for connecing insulation liquid, another connect the return duct of insulation liquid, make main body
Two insulation liquid accommodating cavities of 1 both sides form insulation liquid by the 3rd to the 5th water conservancy diversion runner and exterior insulation liquid supply equipment
Circulatory flow.
With reference to Fig. 3, above-mentioned exhaust port 1h, into liquid interface 1i and two insulations interface 1g, 1j be located at the same of main body 1
End face, four be in crossing distribution.Due to all being concentrated by exhaust port 1h, into liquid interface 1i and two insulation interfaces 1g, 1j
In an end face of nozzle body 1, efficiently solve the exhaust port of existing nozzle, be distributed in spray into liquid interface and insulation interface
The problem of processing difficulties caused by mouth main body, cover board diverse location and cumbersome mixed and disorderly assembling, so that nozzle knot of the present invention
Structure is compact, easy to process, assembling, meets the demand for development of developing technique.
Above-mentioned first to the 5th water conservancy diversion runner is transverse flow channels.First to fourth water conservancy diversion runner 1d, 1e, 1f, 1k is arranged on

End) top surface form the first convex 1m, be separately formed the second convex 1l in two sides of left part, cover board 4 with
Main body 1 flushes after assembling with the surface of the first convex 1m, after the assembling of two side plates 2,5 and main body 1 with corresponding second convex 1l
Surface flush.
In some preferred embodiment, level-one runner 1a length is more than width and depth, in strip.Equally, secondary streams
The length of road 1b is more than width and depth, in strip.
The slope angle of drainage inclined-plane 1s crosses conference and causes bubble to increase, and liquid fluctuating;Slope angle is too small, may cause two
Level runner liquid level is gradually reduced, and discharge velocity is gradually reduced, and the preferred range for draining the slope angle of inclined-plane 1s is 30~60 degree, more preferably
Scope be 35~50 degree.
Further, the bottom surface of main body 1 is going out to flow around aperture 1q to form up big and down small protuberance 1p.Protuberance 1p
Can avoid liquid from go out to flow aperture 1q outflow when produce coacervation.
Can also the performance of nozzle be had an impact by going out to flow the size of aperture 1q, overcurrent seam 3a and exhaust passage.Some compared with
In good embodiment, the aperture that goes out to flow aperture 1q is 0.1-0.6mm, aspect ratio 2-6, it is all go out flow aperture area and with it is described
The area ratio of overcurrent seam 3a is 0.02-0.05, and the area of exhaust passage and the area ratio of overcurrent seam 3a are 0.05-
0.3.In some more preferably embodiment, the aperture for going out to flow aperture 1q is 0.5mm, and aspect ratio 4 is all to go out to flow the face of aperture 1q
Product and with the overcurrent seam 3a area ratio be 0.04, the area of exhaust passage and with the overcurrent seam 3a area ratio be
0.125。
The preferred height ratio of level-one runner 1a and two level runner 1b is 0.2-0.4, and more preferably height is than being 0.3.
The present invention is described in detail above by specific embodiment, these specific descriptions must not believe that the present invention
It is only limited to the content of these embodiments.Those skilled in the art conceive according to the present invention, these are described and combine this area public affairs
Know any improvement, equivalents that general knowledge makes, should be included in the protection domain of the claims in the present invention.
