The specific embodiment
In the following detailed description, with reference to forming its a part of accompanying drawing.In the accompanying drawings, the similarly similar part of symbol ordinary representation, unless context is otherwise noted.The illustrative embodiments of describing in detailed description, accompanying drawing and claims is not intended to limit.In the case of the spirit or scope of theme that do not depart from the application, can adopt other embodiments, and can make other variations.Be appreciated that and can carry out multiple different configuration, replacement, combination, the design forming to the various aspects of general teachings herein that describe, that illustrate in the accompanying drawings herein, and all these forms a part for teachings herein clearly.
Fig. 2 shows according to the schematic diagram of the liquid dispensing apparatus 100 of an embodiment of the application.This liquid dispensing apparatus 100 can be for for example diaphragm plate is carried out to spray treatment, to form the fluid film layer of predetermined thickness in the presumptive area of diaphragm plate.Diaphragm plate is to be for example made up of polyvinyl chloride or polyolefine material.In some instances, this liquid dispensing apparatus 100 can be for spraying such as alcohol etc. for the liquid as lubricant.
As shown in Figure 2, this liquid dispensing apparatus 100 comprises:
Particularly, atomizer 103 can be constructed to the structure of Y-pipe, comprises two breeches pipes that are respectively used to influent and gas, and for spraying the nozzle end of atomized drop.Wherein, the gas flow rate in inflow atomizer 103 is conventionally much larger than flow rate of liquid.In some instances, the fluid flow that liquid controller 115 is supplied to atomizer 103 via liquid supply passage 113 is set to 2 to 10 ls/h, is preferably 2 to 5 ls/h; And the gas flow that Gas controller 111 is supplied to atomizer 103 via gas feed path 109 is set to 100 to 200 ls/h, be preferably 100 to 150 ls/h.Like this, low speed flowing liquid can be torn as droplet shape by high velocity air, or low speed flowing liquid can clash into the obstacle (being for example arranged on the iron plate in atomizer) of special setting and atomization is droplet shape, and then is taken out of nozzle end by high velocity air.
Jet expansion can be constructed to can be with the shape of predetermined spray angle ejection atomized drop, and for example it can be constructed to have seedpod of the lotus shape structure, is substantially scattered with equably several spray orifices on the jet face of this seedpod of the lotus shape structure.In some instances, spout outside can also arrange (for example covering) a cover plate, and this cover plate for example has umbrella or trumpet-shaped diffusion structure, ejects according to predetermined spray angle for guiding atomized liquid from atomizer 103.The structure that is appreciated that above-mentioned atomizer is only example, and atomizer also can adopt various other applicable structure and structures in actual applications.
