Description

Ink injection cartridge assembly

Technical Field

The utility model relates to a print the inkjet ink horn field, especially relate to an annotate black ink horn subassembly.

Background

The printing ink-jet ink box can be divided into an integrated ink box and a split type ink box according to the ink injection type.

The integrated ink box integrates the printing nozzle on the ink box, when the ink in the ink box is used up, a brand new ink box needs to be replaced, which means that a new printing nozzle is replaced at the same time. Higher printing accuracy and quality can be achieved using such an ink cartridge. Because the printing nozzle is replaced along with the ink box, the situation that the printing quality is reduced due to abrasion of the printing nozzle caused by too long service time can not occur. However, this one-piece design also greatly increases the production cost and is always expensive.

The split type ink box is designed to separate the printing nozzle and the ink box. Due to the design that the printing nozzle and the ink box are separated, the design method can lead a user to buy the corresponding ink box to replace, thereby greatly reducing the replacement frequency of the printing nozzle. When the ink in the ink box in use is used up, the user can replace the ink box by himself, and the corresponding printing nozzle needs to be replaced until the printing nozzle in use is damaged. A drawback of this design is that the quality of the text printed by the printer can be significantly degraded when the print head is not replaced in a timely manner. And the split cartridges typically do not allow the user to fill the ink himself at will.

After the integrated ink box is used, a user can refill the empty ink box with ink by himself. However, the user often has to perform improper ink filling operations, which may result in ink leakage and contamination. Meanwhile, when the ink filling port of the ink box is not correctly sealed, the ink leakage is easy to occur, and the situation that the printer is damaged due to ink leakage in the printer can occur in serious cases.

When the ink filling operation is performed, the auxiliary ink filling piece 30 pushes the elastic gasket 32 to abut against the sealing convex points 2240, and under the action of pressure, the elastic gasket 32 is sufficiently compressed and filled between the auxiliary ink filling piece 30 and the valve body end cover 224, so that the ink is prevented from overflowing from a gap between the auxiliary ink filling piece 30 and the valve body end cover 224 during the ink filling operation, and the axial rotation between the auxiliary ink filling piece 30 and the valve body end cover 224 is prevented by the friction force between the auxiliary ink filling piece 30 and the valve body end cover 224.

The sealing convex points 2240 are uniformly distributed on the outer end face of the valve body end cover 224. The arrangement of the sealing protrusions 2240 includes, but is not limited to, uniform array arrangement around the center of the outer end surface of the valve body end cover 224. The preferred arrangement of the sealing protrusions 2240 is that the sealing protrusions are uniformly arranged in a circle center array around the circle center of the outer end surface of the valve body end cover 224, and at least two circles of sealing protrusions are optimally arranged in an array.

The higher the flexibility of the material of the elastic washer 32, the better the gap filling capability when the auxiliary ink filling member 30 and the valve body end cover 224 are pressed, the greater the friction force generated, and the better the effect of preventing the axial rotation between the two. The preferred material of the elastic washer 32 is silicone, which produces the best effect.

The auxiliary ink injection member 30 has a stepped cylindrical shape. This design allows the elastomeric gasket 32 to better seat against the sealing bosses 2240, increasing the seal of the device.

Referring to fig. 6, fig. 6 is a cross-sectional view of a check valve of an ink cartridge assembly according to another embodiment of the present invention. In some embodiments, the valve body main body 222 includes a main body portion 2220 and an insertion portion 2222, the main body portion 2220 and the insertion portion 2222 form a step structure therebetween, the insertion portion 2222 is inserted into the ink injection inlet 102, and an end surface of the main body portion 2220 abuts against the ink cartridge 10; the insertion portion 2222 is provided with the passage outlet 2024.

In some examples, the outer end surface of the insertion portion 2222 is treated with a frosted surface to provide more rigidity during insertion into the ink inlet 102, reducing the likelihood that the insertion portion 2222 will fall out of the ink inlet 102.

In this embodiment, the valve body main body 222 and the valve body end cap 224 are plastic parts, which can reduce the manufacturing cost while maintaining the structural features and corrosion resistance. It will be appreciated that in some other implementations, the valve body 22 and the valve body end cap 224 may be formed of stainless steel. The structure strength is greatly enhanced while the abrasion is not easy to occur and the practical service life is prolonged.

In some embodiments, the check valve 20 includes a sealing gasket 28, the sealing gasket 28 is positioned between the valve core 26 and the valve body end cap 224, and the sealing gasket 28 defines an opening that communicates with the passage inlet 2020.

When the ink filling operation is not performed, the valve core 26 abuts against the surface of the sealing washer 28 under the elastic force of the elastic piece 24 to block the passage inlet 2020, and the sealing washer 28 seals the gap between the valve body end cover 224 and the valve core 26 to prevent the ink from leaking out.

In some examples, the material of the sealing gasket 28 includes, but is not limited to, silicone. The soft and rich elasticity of silica gel material, under the effect of the pressure of propping up of case 26, can be better with case 26 zonulae occludens, prevent that the ink from leaking in the gap of connecting.

In other examples, the central opening of the sealing gasket 28 is circular in shape and has a diameter equal to the diameter of the channel inlet 2020.

In some embodiments, the spool 26 is stepped cylindrical, including an abutment 262 and a mounting 264; the elastic member 24 is a compression spring, one end of the compression spring is sleeved on the mounting portion 264 and abuts against the abutting portion 262, and the elastic member 24 pushes the abutting portion 262 to abut against the inner wall of the valve body end cover 224 and block the passage inlet 2020.

The spool 26 includes, but is not limited to, a time-stepped cylindrical shape. The stepped cylindrical design enables the elastic element 24 to be sleeved outside the mounting portion 264, thereby reducing the position deviation of the elastic element 24 and the valve core 26 caused by long-term use. The design of the stepped cylinder with cylinders of unequal diameters at the two ends also allows better plugging of the passage entrance 2020.

In other embodiments, the valve element 26 may be a steel ball, and the same method of abutment as the stepped cylinder. When the steel ball was annotated the china ink operation each time, promotion portion 3002 all can promote the steel ball and make the steel ball take place some direction squints to make the surface of steel ball be stained with the ink uniformly, thereby the existence of ink makes the steel ball and the elastic component 24, the frictional force between the valve body 22 inner wall diminishes thereby the action that promotion portion 3002 promoted the steel ball becomes lighter when letting annotate the china ink, annotates the china ink operation and becomes easier.
