Abstract
An inkjet cartridge for the ink-jet printer is provided, consisting of a cartridge body and a top cover. An ink supply opening is arranged on the bottom wall of the cartridge body, an air inducing hole and an ink filling hole are provided on the top cover, an ink storage room and a holding room connected with the ink storage room are positioned in the inkjet cartridge, an air inducing leak resistance component mainly composing of a spring and a piston is positioned inside the holding room, one end of the spring is connected with the cartridge body, the other end is connected with the piston, the piston can move in the holding room, and the air inducing hole is connected with the air and the holding room. The structure of the air inducing leak resistance component adopted by the utility model is simple and convenient to manufacture and arrange, and can automatically adjust the pressure in the ink storage room, thereby enabling the inkjet cartridge to create constant pressure ink supply, and preventing the ink from leaking from the air inducing hole.
Description
Technical field
The utility model relates to a kind of print cartridge that ink-jet printer is used, and particularly utilizes air guide leakproof assembly to regulate the print cartridge of Ink Cartridge inner pressure.
Background technology
Along with the progress of ink-jet printer and ink-jet technology, ink-jet printer has been realized the quick output of high quality graphic, and the storable ink capacity of original sponge structure print cartridge is little, is just progressively replaced by no sponge structure print cartridge.But not having the sponge structure print cartridge need be provided with some complicated structures usually and keep the ink supply of print cartridge constant voltage, such as valve etc., increased manufacturing cost, and put to no little inconvenience to installation, do not have the sponge structure print cartridge in addition and have another outstanding problem: because of the variation of external environmental condition, print cartridge in use and discarded print cartridge after abandoning, very easily take place to cause and use inconvenience and environmental pollution from the overflow phenomenon of China ink of the gas port of print cartridge.
Summary of the invention
That main purpose of the present utility model provides is simple in structure, can keep the print cartridge of constant voltage ground to the printhead ink supply within the specific limits;
Another purpose of the present utility model provides and can resist the print cartridge that environmental change produces black liquid seepage.
For achieving the above object, the technical solution adopted in the utility model is: print cartridge comprises a box body and a cover, box body and cover cover the ink storage chamber that the back forms a storage ink, box portion bottom wall is provided with the ink supply port of built-in sealing ring, after print cartridge is put into printer, ink supply port docks with printhead, has gas port and pouring ink hole on the cover.A containing cavity is arranged in the print cartridge, containing cavity communicates by a connected entrance with ink storage chamber, the main air guide leakproof assembly of being made up of spring and piston is built in the containing cavity, spring one end is fixed on the box portion bottom wall, the other end connects piston, piston profile and containing cavity internal face are complementary, form little matched in clearance between piston and containing cavity internal face, little gap seals by the surface tension of ink, this structure can prevent that air from entering in the ink storage chamber by little gap, and piston is moved in containing cavity flexibly.Gas port is communicated with atmosphere and containing cavity.By changing the passage that position of piston is switched on or switched off ink storage chamber and atmosphere.
The air guide leakproof modular construction that the utility model adopts is simple, and manufacturing and installation are all very convenient, and can regulate the pressure in the ink storage chamber automatically, makes print cartridge realize the constant voltage ink supply.In addition, air guide leakproof assembly can make idle print cartridge and discarded print cartridge be in ink storage chamber and the disconnected state of atmosphere by adjusting the pressure in the ink storage chamber, thereby has prevented that ink is by the gas port seepage.
Description of drawings
Fig. 1 is the structural representation after the utility model embodiment vertically cuts open;
Fig. 2 is the utility model embodiment longitudinal sectional view;
Fig. 3 is the working state schematic representation of air guide leakproof assembly when atmosphere enters ink storage chamber of the utility model embodiment;
The utility model is described in further detail below in conjunction with embodiment.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the print cartridge outline is substantially cuboid, comprises box body 1, cover 2 and leakproof air guide assembly, and box body 1 and cover 2 surround the ink storage chamber 11 that ink is deposited in a confession, the diapire of box body 1 is provided with ink supply 12, and sealing ring 13 is built in the ink supply port 12.Have a cylindrical gas port 24 and a taper pouring ink hole 25 on the cover 2, after ink injected ink storage chamber 11, the plug 26 that matches with pouring ink hole 25 with shape sealed.Cylindric containing cavity 21 is arranged in the ink storage chamber 11, and containing cavity wall 22 is one-body molded with cover 2, and the lower end is inserted in 14 li of grooves on box body 1 diapire.Have the microscler connected entrance 23 that is communicated with containing cavity 21 and ink storage chamber 11 on the vertical wall of containing cavity, gas port 24 is communicated with containing cavity 21 and atmosphere.Air guide leakproof assembly mainly is made of spring 31 and piston 32, and be built in the containing cavity 21, spring 31 1 ends are fixed on box body 1 diapire, and the other end connects piston 32, piston 32 can move up and down in containing cavity, and its profile is cylindrical for what match with containing cavity 21 internal faces.Form little matched in clearance between piston 32 and containing cavity 21 inwalls, ink infiltrates little gap after injecting ink storage chamber 11, plays sealing and lubricated effect simultaneously.When the upper wall surface of piston 32 was higher than the top edge of connected entrance 23, atmosphere can not enter ink storage chamber 11, and when the upper wall surface of piston 32 was lower than the top edge of connected entrance 23, atmosphere entered ink storage chamber 11 through gas port 24 and blow vent 23.
Below the working mechanism of air guide leakproof assembly of the present utility model is illustrated in conjunction with its design feature.When printer is worked, along with the ink in the print cartridge constantly is consumed, in ink storage chamber 11, form negative pressure, when negative pressure reached certain numerical value, piston 32 was under the atmospheric effect in the external world, and the thrust that overcomes spring 31 moves downward.When piston 32 moved to its upper wall surface and is lower than connected entrance 23 upper marginal positions, as shown in Figure 3, atmosphere entered ink storage chamber 11 through gas port 24 and connected entrance 23, as shown by arrow A.Gas in the ink storage chamber 11 is replenished, pressure rises, and piston 32 up moves.The upper wall surface of piston 32 is crossed the top edge of connected entrance 23, and on connected entrance 23 was blocked, the passage that atmosphere enters ink storage chamber 11 was cut off.Ink in the ink storage chamber 11 continues to be consumed, and piston 32 repeats said process.So move in circles, the pressure in the ink storage chamber 11 is constantly adjusted, and print cartridge is kept the constant voltage ink supply.
When printer quits work, the variation of ambient temperature can cause that also the pressure in the ink storage chamber 11 changes, piston 32 can change according to the pressure in the ink storage chamber 11 to be done to move or move down, to adjust the pressure in the ink storage chamber 11, make the ink storage chamber 11 of print cartridge finally be in the state of opening with the ambient atmosphere partition, thereby it is excessive to prevent that ink from passing through gas port 24.Equally, after discarded print cartridge was dropped, the residual ink in the ink storage chamber 11 can be not excessive from gas port 24 yet, prevented contaminated environment.
