Plug nozzle, causes the problems such as printing broken string, and follow-up cleaning is the most considerably complicated.Use in prior art is common
The aperture of cotton core is 150-1000 μm, is far longer than the diameter of some impurity, therefore can not be by less for diameter in ink
Contaminant filter falls；If selecting the material that aperture is too small, such as aperture to be less than 20 μm, on the one hand density of material is excessive, inhales
Attached ink very capable, causes ink can not be transmitted to ink supply port smoothly from ink storage chamber, on the other hand, inhales
Attached a large amount of inks cause being fed to printer, reduce the availability of ink；The resin that the application uses
The aperture of sintered material is 20-130 μm, and minimum can filter out the diameter impurity more than 20 μm, compared to existing hole
Footpath is the sponge of 150-1000 μm, and filter effect becomes apparent from.Straight in view of the diameter of most of nozzles and impurity
Footpath, the preferred scheme of the application is the resin sintered material that filling member 4 uses aperture to be 20-130 μm.
The shore hardness of general sponge is less than or equal to 45 degree, and the shore hardness of soft sponge is less than or equal to 30 degree,
Hardness is smaller, on the one hand, be easily deformed, and produces bubble, and on the other hand, the aperture of general sponge is relatively big, sponge
Pore size easily change, impurity easily enters in sponge, blocking sponge micropore, reduce sponge transmission
The ability of liquid.The shore hardness of resin sintered material is 60-70 degree, relative to the general sponge used in prior art
For, hardness strengthens, and is unlikely to deform, it is to avoid the generation of bubble, and aperture is little, and impurity is not easily accessed filling member 4
