Technical Field

The utility model relates to an inkjet formation of image field especially relates to a detachably installs general ink horn in ink jet printer.

Background

In order to meet the requirements of different end users, ink cartridges suitable for ink jet printers are designed to have various capacities, and in appearance, the ink cartridges with various capacities have the same structure and the same occupied space, and the difference is that the amount of ink contained in the ink cartridge with each capacity is different.

From the perspective of compatible ink cartridge manufacturers, in order to maintain the competitiveness of the compatible ink cartridges, the low cost is a factor that is not negligible for the compatible ink cartridge manufacturers, and for the ink cartridges with various capacities, it is preferable that the compatible manufacturers design the ink cartridges with various capacities into a universal type.

According to the thought, the ink box structure which can be commonly used is designed by the existing compatible ink box manufacturers, specifically, the ink box cavity is divided into a plurality of cavities, and the cavities which are suitable for different capacities are completely separated by partition plates, so that the ink box shells with different capacities need to be provided with different insert parts on a mould in advance when being injection-molded by the mould, the operation mode is not beneficial to the simplification of production, and the condition of using errors of the insert parts is easy to occur.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a perspective view of an ink cartridge according to the present invention; fig. 2 is a schematic view of the internal structure of the ink cartridge according to the present invention after the front cover is hidden.

As shown in the drawings, the ink cartridge 10 is attached and detached in the front-rear direction, and includes a cartridge body 11 and a face cover 12 coupled to the cartridge body 11, the cartridge body 11 including an ink outlet 14 disposed in the front and an air inlet 21 disposed above the ink outlet 14, that is, the air inlet 21 is located above the ink outlet 14 in the attachment direction of the ink cartridge 10; further, the ink cartridge 10 further includes a first sealing member 13 for sealing the air inlet 21 and a second sealing member 15 for sealing the ink outlet 14, and the first sealing member 13 and the second sealing member 15 are removed before the ink cartridge 10 is mounted to the inkjet printer.

The box body 11 encloses to form a containing cavity for containing ink, one end of the containing cavity is communicated with the air inlet 21, the other end of the containing cavity is communicated with the ink outlet 14, and the containing cavity is divided into a plurality of communicated cavities, as shown in fig. 2, along the circulation path of air, the containing cavity sequentially comprises a sponge cavity 22, a buffer cavity, a first ink cavity 25, a second ink cavity 26, a third ink cavity 27 and an ink outlet cavity 28, wherein the sponge cavity 22 is communicated with the air inlet 21, the buffer cavity comprises a first buffer cavity 23 and a second buffer cavity 24 which are communicated with each other, the first buffer cavity 23 is communicated with the sponge cavity 22, the second buffer cavity 24 is communicated with the first ink cavity 25, and the sponge cavity 22, the first buffer cavity 23 and the second buffer cavity 24 are arranged from top to bottom; the second buffer chamber 24 communicates with the first ink chamber 25 through a vertical (up-down) passage 31, and the second ink chamber 26 communicates with the third ink chamber 27 through a lateral (front-rear) passage 32; the third ink chamber 27 communicates with the ink outlet chamber 28, the third ink chamber 27 being located in front of the first ink chamber 25 and the second ink chamber 26; the first ink chamber 25 communicates with the second ink chamber 26 through the first communicating port 41 in the vertical direction, and the second ink chamber 26 communicates with the lateral passage 32 through the second communicating port 42 in the vertical direction, preferably, the first communicating port 41 is not opposed to the second communicating port 42 in the up-down direction, and more preferably, the second communicating port 42 is located behind the first communicating port 41, so that the ink in the first ink chamber 25 and the second ink chamber 26 can be completely consumed.

The sponge 16 is installed in the sponge chamber 22, and when the air pressure in the accommodating chamber is reduced due to the reduction of the ink in the ink cartridge 10, air enters the sponge chamber 22 through the air inlet 21, is filtered by the sponge 16 and then reaches the buffer chamber, and is guided to the ink chamber through the vertical passage 31, thereby balancing the air pressure in the accommodating chamber.

The advantage of the structure of the accommodating chamber in the ink cartridge 10 according to the present invention is that the ink cartridge 10 can be filled with different amounts of ink as required, specifically, when the ink is filled into the accommodating chamber from the ink outlet 14, the ink first fills the third ink chamber 27, and then the ink can enter the second ink chamber 26 and the first ink chamber 25 in sequence through the transverse channel 32, that is, when only the third ink chamber 27 is filled, the ink cartridge 10 can be regarded as the first type; when the third ink chamber 27 and the second ink chamber 26 are both filled, the ink cartridge 10 can be regarded as the second type, and as described above, since the first ink chamber 25 and the second ink chamber 26 are arranged in the up-down direction, ink enters the first ink chamber 25 only when the second ink chamber 26 is completely filled and the filling of ink is continued; when the first ink chamber 25, the second ink chamber 26, and the third ink chamber 27 are all filled, the ink cartridge 10 may be regarded as a third type.

Further, because the buffer chamber and the sponge chamber 22 for installing the sponge 16 are also arranged between the first ink chamber 25 and the air inlet 21, even if the ink cartridge 10 of the third type shakes during transportation, the ink can hardly reach the position of the air inlet 21, and thus, the ink overflow phenomenon can not occur after the end user removes the first sealing member 13.

As described above, the accommodating chamber of the ink cartridge 10 of the present invention is divided into a plurality of communicating ink chambers, one of the ink chambers (the third ink chamber) 27 is communicated with the ink outlet chamber 28, and the other ink chambers are distributed in the up-down direction of the ink cartridge 10, so that when injecting ink from the ink outlet 14, a predetermined amount of ink can be injected as required, and a manufacturer of a compatible ink cartridge only needs to produce one type of ink cartridge housing 11, and does not need to produce the ink cartridge housing 11 for each type of capacity, which is beneficial to simplifying the production of the ink cartridge 10, and a buffer chamber is further provided between the ink chamber (the first ink chamber) 25 farthest from the ink outlet 14 and the air inlet 21, so that the ink in the ink chamber cannot easily flow back to the air inlet 21, and the ink can be effectively prevented from overflowing from the air inlet 21.
