Abstract

The invention relates to a no-sponge separated ink box. The feature is that it is made up from ink box and clip component. The box, which is made up of ink storehouse, box, air intake tube, steel ball type one way valve, and ink core, is laid in the clip component. The advantages of the invention are: absolutely solving the ink leakage phenomena; taking the place of sponge, improving the fluency of ink in the box; avoiding remnant ink phenomena; lowering cost; prolonging the useful life of ink box; and the single structure could be changed to separate structure and is suited to kinds type of ink box for EPSON printer.

Description

The split type ink cartridges of no sponge

Technical field

The present invention relates to the split type ink cartridges of a kind of no sponge, can be used for the printer of the various models of EPSON, belong to the ink cartridges technical field.

Background technology

The ink cartridges of using as shown in Figure 1 at present, be single structure, sponge SG1 just is contained in one side in the ink cartridges PP1, make the function of gas flow modulation and absorption ink with sponge, circular ink storing chamber PP3 places the another side of ink cartridges PP1, ink storing chamber PP3 lower end is provided with Mo Xin PP4, is provided with spring R2 below sponge SG1, regulates ink cartridges PP1 internal pressure by spring R2.

The shortcoming that the ink cartridges of sponge is housed has:

1. sponge has the characteristic of absorption ink, makes the real quantity of ink that uses of user to come to such an extent that lack than sign, and residual China ink amount is big;

2. the structure of sponge itself is to adopt the mode of foaming produced, so sponge itself can reduce the fluency of ink, so that the life-span of ink cartridges at most only has 2 years;

3. sponge is loaded on ink cartridges and can causes small air to enter the ink cartridges body, when the electronic circuit of print head is assigned the signal of ejection ink droplet, and the non-ink of ink cartridges ejection but small air,

Make print quality that nun's thread can take place, as shown in Figure 2;

4. the ink in the sealing ink cartridges is because external transportation and climate reasons can produce temperature rise, thus generation ink leak phenomenon.

Summary of the invention

The objective of the invention is to invent good, the residual China ink amount of a kind of print quality little, not ink leak, the split type ink cartridges of repeatedly used no sponge.

For realizing above purpose, technical scheme of the present invention provides the split type ink cartridges of a kind of no sponge, it is characterized in that, be made up of ink cartridge and clamp, ink cartridge places in the clamp, and described ink cartridge is made up of ink storing chamber, box body, air inlet pipe, ball type one-way cock, Mo Xin, ink storing chamber places a side of ink cartridge, air inlet pipe is located at the upper end of ink cartridge opposite side, and the lower end of air inlet pipe connects the ball type one-way cock, and Mo Xin is located at the lower end of ink storing chamber.

One side of described ink storing chamber is provided with a fine ink-guiding passage.

Described ball type one-way cock is made up of valve body and steel ball, and steel ball moving up and down places the protrusion place of valve body internal channel.

Be provided with the passage at protrusion place in the middle of in the described valve body, its two ends diameter is less than diameter of the steel ball, mid diameter is greater than diameter of the steel ball, interior lower end at passage protrusion place is provided with one can make steel ball and the apertured step of passage, described valve body material is a silica gel, and described steel ball material is a stainless steel.

Described black core is made up of spring, piston, sealing ring, ink hole envelope film, shell, piston places the spring lower end, sealing ring places the inside of ink hole envelope film, outside spring, be provided with the shell that is higher than spring, be provided with the hole of band filter screen in the upper end of shell, be provided with the return-air hole of band filter screen in the centre of shell.The hole of described band filter screen is greater than the return-air hole of band filter screen.

Described clamp is single deck tape-recorder clamp and two clip body.

The present invention is provided with a fine ink-guiding passage on one side of ink storing chamber, make the ink-guiding passage lower port near print cartridge at the bottom of, utilize siphon principle, when pressure by outside clamp-on, up push ink and enter tiny ink-guiding passage, make the residual black amount of ink to improve, almost can use up fully to ink storing chamber.

The present invention uses Dan to replace sponge Xiang Fa Door and controls and regulate air balance, when air pressure Shun Inter changes greatly, the air push steel ball of steel ball upper end moves down, air can freely enter from upper end Cis when steel ball dropped to step, and the ink in print cartridge, during the Volume Changes that produces because of pressure, ink promotes steel ball to rising and up moves, steel ball rises and check valve closely cooperates stops the ink ejection, Dan has controlled the inflow of air Xiang Fa Door like this, also stop ink up to rise, the quality Ask topic of ink leak just can not take place.

Material of the present invention adopts silica gel, be to make it produce distortion according to silica gel is exerted pressure, and silica gel has the characteristic of seal, can allow air airtight in front end with the thin design of inwall, add behind the steel ball when Ink Cartridge inner pressure is excessive, the steel ball Top And extruding silica gel that can make progress, closed immediately, make ink can up not go here and there liter, just a large amount of excessive ink leak problem of ink can not take place, thereby reach stable purpose, do not use sponge can also stablize ink and air-flow like this, also reach pressure balanced effect.

The present invention increases an ink return-air hole, when printing speed, can regulate ink supply, the phenomenon of ink supply deficiency when improving printing speed.

Advantage of the present invention is:

The Lou Mo Now that takes place when 1, solving because of environment for use temperature, pressure difference and traffic condition change fully resembles;

2, the silica gel front end is thinner because of its wall, and when the print cartridge internal pressure was excessive, the silica gel of front end can shrink, and increases air tightness;

3, replace sponge material, improved the fluency of ink in the ink cartridges, improved when print quality makes printing and the nun's thread phenomenon can not take place;

4, avoid residual black phenomenon, increased the actual use amount of ink;

5, change the sponge framework of original print cartridge, need not to use vacuum packaging, and can adopt general seal package, reduced manufacturing cost;

6, adopt the stainless steel steel ball, can forever deposit and can not get rusty, can prolong the service life of print cartridge.

7. change the two separable independence separately into by single structure, and one-tenth capable of being combined is suitable for the ink cartridges of the various model printers of EPSON.
