Deng).And the length of each exhalant canal 21 be preferably designed for be greater than 0 be less than or equal to 50mm, for example, 10mm, 18mm, 26mm,
35mm, 42mm, 50mm etc..
For example, the length of slit mouth spray is 400mm, is highly 3.7mm, width 0.8mm, each exhalant canal 21
Length is 18mm or other sizes, and the size of slit mouth spray 22 and exhalant canal depends primarily on the size of wiring board, is driven
The pressure that device applies to solution is moved, and the factors such as jet velocity for spraying to wiring board determine that specific size need to be according to reality
Depending on service condition.
As preferred embodiment, several exhalant canals 21 along injection structure 2 equal spacing in length direction be distributed,
Accordingly, the setting of the through-hole 11 on diversion pipe 1 also equally, so that the solution distribution in exhalant canal 21 is more evenly,
It further ensures that solution is ejected through slit mouth spray 22, forms waterfall type jet flow more evenly, improve water knife and spray solution
Uniformity.
As preferred embodiment, as shown in Figure 1, Figure 2 and Figure 4, above-mentioned water knife further includes pipe fitting 3 and closure knot
Structure 4, pipe fitting 3 are mounted on the one end of diversion pipe 1, and plugging structure 4 closes the other end for being mounted on diversion pipe 1.Pipe fitting 3
Setting convenient for diversion pipe 1 is connect with the pipeline of conveying device, plugging structure 4 blocks the other end of diversion pipe 1, so that leading
Solution in flow tube 1 can only be ejected through exhalant canal 21.
As the preferred of plugging structure 4, plugging structure 4 is pipe cap, and pipe cap welding is on the end of diversion pipe 1, Huo Zheyu
The end of diversion pipe 1 is integrally formed, or is fixed on pipe cap on the end of diversion pipe 1 using other fixed forms.
As deformation, plugging structure can also be other structures, need to only meet and block the one end of diversion pipe 1, so that
Solution in diversion pipe 1 can only be ejected through exhalant canal 21.
As further preferred embodiment, fixed form between the bottom and diversion pipe 1 of injection structure 2, preferably
Using welding, be perhaps bonded perhaps by the bottom of injection structure 2 be integrally formed with diversion pipe 1 or it is in the prior art other
Fixed form.More preferably, the bottom surface of injection structure 2 is the arcwall face matched with 1 outside wall surface of diversion pipe.
As preferred embodiment, the material of injection structure is preferably made of PVC material.
