Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Fig. 1 is the structural schematic diagram of the ink discharge device of continuous ink feeding described in the utility model.As shown in Figure 1, the continuous confession
The ink discharge device of ink includes ink storage box 10, connection valve 40, ink-feeding tube 20, print head 30 and bracket 50.The ink-feeding tube 20
One end is connected to the ink storage box 10, and other end is connect with connection valve 40, the print head 30 of connecting valve and ink discharge device
Connection.In the ink to print cartridge exported in print head 30 equipped with built-in print cartridge, connecting valve.
Fig. 2 is the structural schematic diagram of the connection valve 40 of the ink discharge device of continuous ink feeding described in Fig. 1, wherein communicating valve
Door 40 is in close state.Fig. 3 is the structural schematic diagram of the connection valve 40 of the ink discharge device of continuous ink feeding described in Fig. 1,
In, connection valve 40 is in the open state.As shown in Figures 2 and 3, the connection valve 40 includes a valve body 41, the valve body
A cavity, ink entrance 42 and ink outlet port 43 are equipped in 41, the ink entrance 42 connects with the cavity respectively with the ink outlet port 43
It is logical.Specifically, the ink entrance 42 is set to the side wall of the connection valve 40, and from the side wall of the cavity and the cavity
Connection, the ink outlet port 43 are set to the bottom of the communicating valve, and are connected to from the bottom wall of the cavity with the cavity.It is described
Ink outlet port 43 is connected to the print head 30, and the ink in the ink storage box 10 is by the ink-feeding tube 20 through the ink entrance 42
Into the cavity, enter the print head 30 from the ink outlet port 43.
The cavity is taper, and big end is set in the ink outlet port 43, the cavity close to the ink entrance 42, small end
There is an adjusting rod 44, the adjusting rod 44 is arranged with several sealing rings 46 along the length direction of the cavity.The sealing 442
Equipped with several cricoid grooves, the sealing ring 46 is set in the groove, and the sealing ring 46 is along far from described out of ink
The orient diameter of mouth 43 becomes larger.One end of the adjusting rod 44 is arranged with elastomer 45, and top contacts at the cavity
Roof, other end stretch out from the ink outlet port 43 and contact 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 diameter of the sealing 442 is greater than the upper interconnecting piece 441 and lower interconnecting piece 443 and described
Sealing ring 46 is sheathed on the sealing 442, and the lower interconnecting piece 443 stretches out from the ink outlet port 43 and contacts at described beat
Print head 30.The lower interconnecting piece 443 is equipped with the diversion trench 443a that several length directions along the lower interconnecting piece 443 extend.Institute
The area for stating the cross section of diversion trench 443a becomes larger along the direction far from the ink outlet port 43 to export ink, prevents ink
It splashes down.
