Abstract

An ink cartridge, comprising: an upper cover, a bottom shell without any rib inside and protecting the ink storage part of the porous body, a porous body for storing ink and controlling the flow of ink, and two partitions dividing the inner space of the ink cartridge according to the position of the inkjet head , characterized in that: at least one partition is curved, and the partition divides the interior of the ink cartridge into three spaces. There is a filter cloth for filtering and fixing the porous body at the contact point between the porous body and the inkjet head.

Description

a cartridge

technical field

The utility model relates to an ink box.

Background technique:

At present, there is an ink cartridge with a cotton wick in the market, which includes an ink-absorbing material and an ink-supply element that delivers ink from the ink-absorbing material. Among them, the ink supply element is composed of fiber bundles, which regulate the amount of ink so that it can only flow in one direction. The ink supply element is what we call the wick. There are many ribs inside the ink cartridge, which greatly reduces the volume of the ink-absorbing material, thereby reducing the number of printed pages.

Contents of the utility model:

In view of the above defects of the ink cartridge, the main purpose of the present invention is to provide an ink cartridge that can provide the maximum ink capacity within the space of the ink cartridge.

The technical scheme of the utility model is:

A cartridge comprising:

- cover,

- the bottom shell without any ribs inside and protecting the ink storage part of the porous body,

a porous body that stores ink and controls its flow,

According to the position of the inkjet head, the two partitions that divide the inner space of the ink cartridge,

It is characterized in that at least one partition is curved, and the partition divides the interior of the ink cartridge into three spaces.

According to the utility model, one of the partition walls is curved, and the other partition wall is planar.

The curved surface is smooth.

The two partition walls intersect on the edge side wall inside the ink box or are completely separated.

The upper cover is provided with an air inlet and a buffer chamber for preventing ink from leaking out from the air inlet.

There is a filter cloth for filtering and fixing the porous body at the contact point between the porous body and the inkjet head.

Because the utility model adopts the above-mentioned technical scheme, thereby in the inner space of the ink cartridge, all the ribs are canceled, and only the porous ink storage body is used to increase the ink capacity. The upper cover is provided with an air inlet and a buffer chamber to prevent ink from leaking from the air inlet to the outside when the external environment changes. The inner space of the bottom shell is divided by a partition, and each chamber has a porous ink storage body to store ink. There is a filter cloth at the lower end of the porous ink storage body, which is directly in contact with the inkjet head, which can prevent the porous body from leaking and filtering ink.

Detailed ways:

Below in conjunction with embodiment of the utility model and accompanying drawing thereof, the utility model is described in further detail:

as the picture shows:

A cartridge comprising:

- upper cover 1,

- the bottom case 2 without any ribs inside and protecting the ink storage part of the porous body,

A porous body 3 that stores ink and controls ink flow,

According to the position of the inkjet head, the two partition walls 6 and 7 that divide the inner space of the ink cartridge,

It is characterized in that at least one partition 6 is curved, and the partition divides the interior of the ink cartridge into three spaces.

According to this embodiment, one of the partition walls 6 is curved, and the other partition wall 7 is planar.

The curved surface 6 is smooth.

The two partition walls 6, 7 may intersect on the side wall of the inner edge of the ink cartridge. Of course, the two partitions can also be completely separated.

The upper cover 1 is provided with an air inlet 8 and a buffer chamber 5 for preventing ink from leaking to the outside from the air inlet.

There is a filter cloth 4 for filtering and fixing the porous body at the contact point between the porous body and the inkjet head.

The upper cover is provided with an air inlet 8 and a buffer chamber 5, which can prevent ink from leaking from the air inlet to the outside when the external environment changes; the bottom shell 2 has no ribs inside, only a porous body 3, which can increase the amount of ink contained . Each chamber has a porous body to store ink, and a filter cloth is provided at the lower end of the porous body to directly contact the inkjet head, so as to prevent leakage and filter ink from the porous body.

Claims (6)
