Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Fig. 1 is the structural schematic diagram of high-precision ink discharge device of the present invention.As shown in Figure 1, the high-precision ink discharge device
Including ink storage box 10, connection valve 40, ink-feeding tube 20, print head 30 and bracket 50.One end of the ink-feeding tube 20 and the storage
Print cartridge 10 is connected to, and other end is connect with connection valve 40, and the print head 30 of connecting valve and ink discharge device connects.Print head
It is equipped with built-in print cartridge in 30, is connected in the ink to print cartridge that valve 40 exports.
Fig. 2 is the structural schematic diagram of the connection valve 40 of high-precision ink discharge device described in Fig. 1, wherein connection valve 40
It is in close state.As shown in Fig. 2, the connection valve 40 includes a valve body 41, a cavity, ink feed are equipped in the valve body 41
Mouth 42 and ink outlet port 43, the ink entrance 42 are connected to the cavity respectively with the ink outlet port 43.Specifically, the ink entrance
42 are set to the side wall of the connection valve 40, and are connected to from the side wall of the cavity with the cavity, and the ink outlet port 43 is set
It is connected in the bottom of the communicating valve, and from the bottom wall of the cavity with the cavity.The ink outlet port 43 and the printing
First 30 are connected to, and the ink in the ink storage box 10 enters the cavity through the ink entrance 42 by the ink-feeding tube 20, from institute
It states ink outlet port 43 and enters the print head 30.
An adjusting rod 44 is equipped in the cavity, the adjusting rod 44 is arranged with several close along the length direction of the cavity
Seal 46.The sealing 442 is equipped with several cricoid grooves, and the sealing ring 46 is set in the groove, and described close
Seal 46 becomes larger along the orient diameter far from the ink outlet port 43.One end of the adjusting rod 44 is arranged with elastomer 45,
Top contacts at the roof of the cavity, and other end stretches out from the ink outlet port 43 and contacts at the print head 30.
The adjusting rod 44 includes upper interconnecting piece 441, sealing 442 and lower interconnecting piece 443,441 sets of the upper interconnecting piece
Equipped with the elastomer 45, the sealing 442 is taper, and diameter is greater than the upper interconnecting piece 441 and lower interconnecting piece 443 simultaneously
And the sealing ring 46 is sheathed on the sealing 442.The lower interconnecting piece 443 is stretched out and is contacted at from the ink outlet port 43
The print head 30.The lower interconnecting piece 443 is equipped with the diversion trench that several length directions along the lower interconnecting piece 443 extend
443a.The area of the cross section of the diversion trench 443a becomes larger along the direction far from the ink outlet port 43, for exporting ink
Water prevents ink unrestrained.
The bracket 50 includes pedestal 52 and cover board 51, and the cover board 51 is articulated on the pedestal 52, and the lid
Plate 51 is connect with the connection valve 40.When the cover board 51 pedestal 52 relatively is overturn, the cover board 51 drives described
Connection valve 40 is detached from from the print head 30, so that the adjusting rod 44 of the connection valve 40 is under the elastomer 45 effect
It is mobile until the sealing ring 46 contradicts on the boss 47 of the cavity close to the ink outlet port 43.
When normal work, the lower interconnecting piece 443 of adjusting rod 44 stretches out from ink outlet port 43 and contradicts the print cartridge in print head 30,
So that 45 contraction distortion of elastomer.At this point, the ink warp there are gap between sealing ring 46 and the side wall of cavity, in ink storage box 10
Ink-feeding tube 20, out of, ink entrance 42 is input to connection valve 40 cavity.After ink enters cavity, from the cavity of sealing ring 46
Side wall is exported from ink outlet port 43 to the print cartridge of print head 30.
When needing to change ink, the cover board 51 of bracket 50 is opened, so that being connected to the connection valve 40 of cover board 51 from printing
It is detached from first 30 print cartridge, adjusting rod 44 moves down under the elastic force effect of elastomer 45 and the conflict of sealing ring 46 is being held
On the boss 47 of chamber, so that ink entrance 42 and ink outlet port 43 are isolated, ink cannot be exported from ink outlet port 43.Therefore print cartridge is being changed
During ink cannot be revealed from ink outlet port 43.
Finally, it should be noted that these are only the preferred embodiment of the present invention, it is not intended to restrict the invention, although
Referring to embodiment, invention is explained in detail, for those skilled in the art, still can be to aforementioned
Technical solution documented by each embodiment is modified or equivalent replacement of some of the technical features, but it is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in protection of the invention
Within the scope of.
