Description
Technical Field
The invention relates to an ink box with a novel structure.
Background
Along with the development of internet technology, the popularization of computer, printer application is very general, and ink jet printer has small, easy operation is convenient, print the advantage that the noise is low and the price is cheaper, receives small-size user's liking deeply. Ink jet printers require the use of ink cartridges that provide ink to the printer. The ink cartridge mainly refers to a part of an ink jet printer for storing printing ink and finally completing printing. The method can be divided into the following steps: split type ink horn and integral type ink horn.
The integrated ink box integrates the spray head on the ink box, and when the ink is used up, a new ink box is replaced, namely a new printing head is replaced at the same time. The split type ink cartridge refers to a product in which the head and the ink cartridge are designed to be separated. The starting point of the structural design is mainly to reduce the printing cost, because the ink box is not integrated on the printing spray head, the printing spray head can be continuously used when the ink box is invalid, meanwhile, the disassembly and assembly process of the ink box by a user is simplified, and the chance of artificial damage to a printer is reduced; however, the ink cartridge structure has obvious defects that the spray head cannot be updated in time, and the quality of the printer naturally declines along with the increase of the working time of the printer until the spray head is damaged. The products of Epson are mostly split type ink cartridges.
No matter split type ink horn or integral type ink horn, how guarantee the ink in the ink horn from beginning to consume the in-process that the whole use, it is very important that the paper is printed all very clearly, when just beginning to install the use unlike present many brands ink horn, the paper prints more clearly, but along with ink in the ink horn gradually becomes less, the paper of printing just becomes more and more unclear.

A printer adopts the ink box of the invention.
Compared with the prior art, the invention has the beneficial effects that: the invention is especially suitable for occasions with very high requirements on printing effect, especially on consistency of definition of printing paper. Many of the ink cartridges in the prior art rely on a negative pressure adjusting mechanism, once a left chamber generates negative pressure, air above a right chamber enters the left chamber through a guide structure on the right side and then slowly enters the inner upper part of the left chamber, so that the air pressure of the left chamber is increased to force liquid in the left chamber to flow to the right chamber, the liquid level of the right chamber is restored to the original height again, and the air above the right chamber needs to overcome the layer resistance of ink to reach the inner upper part of the left chamber. The plurality of convex plates have the advantages that the path of the air outside the ink box body reaching the upper part of the left inner part of the ink box can be greatly shortened, the plurality of convex plates are arranged from left to right, the air outlet hole at the lower part of the leftmost convex plate is closer to the upper surface of the ink box body, and the path of the external air entering the ink box is physically shortened by the design;
the main balance pipe and the branch balance pipes are especially designed, when a printer nozzle sprays ink, generated suction is applied to the branch balance pipes, so that the branch balance pipes can accelerate the time for air outside the ink box body to enter the ink box body, the time for the liquid level on the right side of the N-th convex plate to recover the original height is shortened, the designed main balance pipe has another function of shortening the time for the liquid on the left side of the N-th convex plate to flow to the right side, and the time for the liquid level on the right side of the N-th convex plate to establish dynamic balance is greatly shortened. The inner diameter section of the main balance pipe is smaller than the radial section of the ink outlet, the ratio of the inner diameter section to the radial section of the ink outlet is preferably smaller than 1/8, otherwise the dynamic constant liquid level on the right side of the Nth convex plate is easily damaged and cannot be established again. The port of the main balance tube should be located on the inner right side of the ink outlet. The reason for needing a plurality of convex plates is that once a liquid level sensor on a certain convex plate is submerged, a corresponding valve needs to be closed, otherwise, external air can directly establish a passage with air above the inside of the ink box body without passing through liquid, and the liquid level on the right side of the N-th convex plate can not be restored to the dynamic constant liquid level height.
The ink box provided by the invention can completely use up the ink, and does not waste resources, thereby protecting the environment.
