Description
Technical field
The utility model relates to print cartridge that is applied to ink-jet printer and the equilibrated valve that is applied to this print cartridge.Particularly be applied to ink-jet printer with sponge as ink sticking body in the ink storage chamber, or utilize the print cartridge of its inner space storage ink and equilibrated valve thereof merely.
Background technology
One of common inking mode between ink-jet printer and its supporting print cartridge, be to insert in the print cartridge ink outlet port by the ink supply pin that will have black fluid through-hole, the ink supply needle-penetration the ink outlet port end along or the inner chamber diaphragm seal or the diaphragm seal that are provided with, make black liquid flow into from ink outlet port that the mode of the black fluid through-hole the ink supply pin realizes.Usually the ink supply pin adopts hardness or very large metal material of intensity or plastics preparation, and print cartridge then adopts hardness or the bigger plastics preparation of intensity.Therefore, ink supply pin and print cartridge all have bigger rigidity, and plasticity is relatively poor.Under this state,, can also prevent that black liquid from leaking, and then also must be equipped with necessary seal means simultaneously between ink supply pin and print cartridge ink outlet port if will between ink supply pin and print cartridge, realize the transmission of black liquid.Common seal means normally is provided with sealing ring in ink supply port.Early stage ink-cases of printers often uses its middle part to have the sealing ring of through hole.But this sealing ring banding ink supply pin shank outer surface provides black liquid sealing function between shank and print cartridge ink outlet port, and the black liquid in the print cartridge can only be flowed out by the black fluid through-hole from the ink supply pin.This print cartridge frame mode because sealing ring itself has through hole, causes in the print cartridge process is installed, can produce a spot of black liquid when removing the ink outlet port diaphragm seal reveals, and when the dismounting print cartridge, the residual China ink in the print cartridge also can flow out by the self sealss ring through hole, causes working environment to pollute.
China utility model patent specification CN03201870 can not realize blocking the technical problem of black liquid passage at above-mentioned sealing ring, and a kind of sealing ring that integrates clearance seal function and pathway closure function is provided.The sealing circle comprises the elastomer of a tubulose.There is upwardly extending ink supply needle guide hand-hole elastomeric lower end.This entrance hole is not to be through hole, and its top is a capping film, and capping film has certain thickness, and there is the slit of connection entrance hole inside and capping film upper space at the capping film middle part.This slit is in air-tight state under free state, liquid can not pass through.This sealing ring that has self-closing function, its entrance hole that cooperates with the ink supply pin must rely on the elasticity of sealing ring material and ink supply pin to form interference fit, could between entrance hole and ink supply pin, form effective seal, so require the diameter of entrance hole under the nature can not be greater than the ink supply pin.Usually, the diameter of entrance hole is slightly smaller than ink supply pin shank diameter under the nature.Like this, under confined state, entrance hole ability banding ink supply pin shank surface forms effectively sealing.Because there be certain distance in the ink supply needle guide hand-hole on the sealing ring with capping film at it on axially, and then between capping film and the entrance hole that sealed by the ink supply pin, form air cavity.Therefore when ink supply pin insertion sealing ring entrance hole, the sealing effect of Xing Chenging at first puts on pressure on the air in the air cavity between the two.Along with of the further propelling of ink supply pin along entrance hole, air by compression, a part will be pressed in the print cartridge along the capping film slit, and will be a part of then be pressed into ink supply pin syringe needle inside along the black fluid through-hole of ink supply pin.These air that enter ink supply pin syringe needle inside will absorb the black hydraulic coupling in the ink supply pin China ink fluid through-hole, the perhaps black liquid release pressure in ink supply pin China ink fluid through-hole conversely, cause the black hydraulic coupling in the ink supply pin China ink fluid through-hole to fluctuate, influence the harmony of the black flow quantity that flows to recording mediums such as paper, final deterioration print quality.
