Abstract
The utility model provides an inkjet head for bio-print; a hydrophobic coating is covered at an inner cavity of the inkjet head and a nozzle surface. The hydrophobic coating is added to the inner cavity of the inkjet head and the nozzle surface for the utility model; adhesion phenomenon of the cell to the inner cavity of the inkjet head and the nozzle surface is decreased, and adhesion role of the cell to the inner cavity of the inkjet head and the nozzle surface can be effectively reduced, which causes smooth conduction of biological print.
Description
Technical field
The utility model relates to a kind of ink gun that is used for biometric print.
Background technology
Utilize traditional ink-jet printer (as Canon.RTM.Bubble Jet 2100 Print, HP.RTM.DeskJet 550C Print), its circuit and control program etc. are made suitable modification, can and be used for cell with the ink-jet printer repacking and print.This technology has had multinomial related application at present in the world since exploitation in 2002.
Must make all repackings and could be fit to the requirement that cell is printed although be used for the ink-jet printer of biometric print, be used for the ink gun that its China ink of ink-jet printer of biometric print adopts conventional ink jet printers as first at present, not do any improvement.Because the biological ink that is used for the cell inkjet printing is cell suspending liquid normally, the performance that this biological ink prevents to condense is far away from the traditional ink of inkjet printing; And because the influence of cell deadweight and cell hydrophilic is therefore common in print procedure, cell precipitates easily and adheres to; Because ink gun inner chamber and nozzle surface are narrow, cause ink gun and nozzle blockage simultaneously.
Existing thermal ink jet-print head technology shown in Figure 1.Its operation principle is by the electrical heating elements (normally thermal resistance) 1 on the ink jet-print head (silicon base of inkjet ink chamber), heating rapidly in the number microsecond, make the liquid ink vaporization of nozzle bottom and form bubble 2, consequent bulbs of pressure compressing ink droplet 3 overcomes surface tension and squeezes out nozzle fast, the output medium surface forms pattern or character.The ink droplet of spray nozzle front end sprays because of extruding, and the rear end begins to separate because of the contraction of ink makes ink droplet, and ink droplet just separates fully with ink in the nozzle behind the bubble collapse, thereby finishes the process of an ink-jet.Up to produce steam again and form ink droplet next time.The bubble printer so this ink-jet printer is otherwise known as sometimes.Present color spray printer ink droplet volume mainly contains 6 microlitres, 4 microlitres, even 3 microlitres (as: Epson ink-jet printer R230).When using biological ink, because used ink-jet printer can reach 3 microlitres at present, it is big just in time to hold a cell, and the every ink droplet that is sprayed is just containing a cell 4 usually.
As previously mentioned, because the influence of cell deadweight and cell hydrophilic, therefore common in print procedure, cell precipitates easily and sticks to ink gun inner chamber and nozzle surface, can cause ink gun and nozzle blockage in a few minutes, and biometric print can not normally be carried out.
The utility model content
Technical problem to be solved in the utility model is the deficiency at prior art, and purpose is to provide a kind of cell that can effectively reduce to the adhesive attraction of ink gun inner chamber and nozzle surface, impels the smooth and easy ink gun that carries out of biometric print.
The utility model is realized above-mentioned purpose by the following technical solutions:
A kind of ink gun that is used for biometric print is provided, is coated with hydrophobic coating at the surface of internal cavity and the nozzle surface of ink gun.
Described hydrophobic coating can select for use existing multiple material to apply preferred resistant to elevated temperatures organic silicon coating, silicate coating (as glass) and quartzy coating
The utility model ink gun inner chamber and nozzle surface with good biocompatibility, toxicity is little, hydrophobic performance good, the additional hydrophobic coating of the coating material of Heat stability is good, use and do not stop up to reduce the adhesion of cell, can reach 24 hours ink gun inner chamber and nozzle surface.

Fig. 2 is the cutaway view of ink gun of the present utility model.
The specific embodiment
Below further specify technical scheme of the present invention by specific embodiment.
See Fig. 1.Figure 1 shows that common ink jet-print head.Electrical heating elements 11 on the ink gun 1 makes the liquid ink vaporization and the formation bubble 2 of the bottom of nozzle 12, produces ink droplet 3 thus and squeezes out nozzle 12 fast, just in time holds a cell 4 in the ink droplet 3.Because the influence of cell deadweight and cell hydrophilic, cell precipitates gradually and sticks to ink gun inner chamber and nozzle surface, causes ink gun and nozzle blockage, and common this ink gun will stop up after using 3-5 minute fully.
See Fig. 2, Figure 2 shows that the ink jet-print head that has increased hydrophobic coating.Electrical heating elements 11 on the ink gun 1 makes the liquid ink vaporization and the formation bubble 2 of the bottom of nozzle 12, produces ink droplet 3 thus and squeezes out nozzle 12 fast, just in time holds a cell 4 in the ink droplet 3.At ink gun inner chamber 13 and nozzle 12 surfaces one deck organic silicon coating 5 is arranged, coating 5 plays and reduces the effect that cell adheres to and precipitates, and can normally use 24 hours.
