Viscosity resistance between chamber is greater than the gravity of spraying liquid, by this manner, that is, first pressurizes when spray equipment does not work
When structure and the second pressure structure do not apply pressure to spraying liquid, spraying liquid will not be flowed out from spray equipment.Work as spray
When coating device works, the first pressure structure and the second pressure structure apply pressure to spraying liquid, so that the spray in fluid chamber
The driving force that coating liquid is subject to is greater than its viscosity resistance between fluid chamber wall, sprays so that spraying liquid is exported along spray equipment
The flowing of coating liquid direction, and then exported from the liquid outlet of spray equipment.
In conclusion spraying liquid of the present invention under the cooperation of the first pressure structure and the second pressure structure, improves spray
Coating liquid exports the stress condition in spraying liquid direction in spray equipment, and then reduces spray equipment drip, to meet processing procedure
It is required that improve product yield.
Mode the above is only the implementation of the present invention is not intended to limit the scope of the invention, all to utilize this
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content, it is relevant to be applied directly or indirectly in other
Technical field is included within the scope of the present invention.
