[0057] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0058] In the related art, when the ink in the existing ink cartridge box 1 is used up, the user has to refill the ink, which is troublesome to operate and the ink may be easily spilled.

[0059] Example 1

[0060] Figure 1-Figure 10 The structure diagram of a printer ink bag that is easy to replace according to an embodiment of the utility model is shown. Figure 1-Figure 10 As shown, the ink sac may include:

[0061] A print head 2, which is detachably mounted on the printer;

[0062] The ink bag box 1 and the print head 2 are detachably mounted;

[0063] The first buckle 1.1.2 is arranged on the ink bag box 1, and a first buckle hole 2.8 is opened on the print head 2. The first buckle 1.1.2 is detachably connected to the first buckle hole 2.8.

[0064] In this embodiment, three primary colors or three primary colors plus black ink are added to the ink bag box 1. By providing a first buckle 1.1.2 on the ink bag box 1, it is convenient to quickly install and remove the ink bag box 1 and the print head 2. The ink bag box 1 is aligned with the print head 2, and the ink bag box 1 is pressed downward to make the first buckle 1.1.2 engage with the first buckle hole 2.8 on the printer, thereby realizing quick installation of the ink bag box 1. When the ink bag box 1 needs to be removed, the end of the first buckle 1.1.2 away from the ink bag box 1 is pressed to separate the buckle from the first buckle hole 2.8, and the ink bag box 1 is lifted upward while pressing the buckle away from the end of the ink bag box 1, thereby realizing quick removal of the ink bag box 1.

[0065] By providing a first buckle 1.1.2 on one side of the ink bag box 1 and providing a first buckle hole 2.8 on the print head 2, the ink bag box 1 can be quickly disassembled and installed with the print head 2 through the first buckle 1.1.2, so that the ink bag box 1 can be replaced conveniently.

[0066] like Figure 1-Figure 4 As shown, in one embodiment,

[0067] One end of the first buckle 1.1.2 is connected to the ink bag box 1, and the end of the first buckle 1.1.2 away from the ink bag box 1 has a removal key. The first buckle 1.1.2 also has a first protrusion 1.1.3. When the ink bag box 1 is installed on the printer, the first protrusion 1.1.3 is engaged with the first buckle hole 2.8.

[0068] In this embodiment, the cross-sectional view of the first buckle 1.1.2 is "J"-shaped, the bottom of the first buckle 1.1.2 is connected to the ink bag box 1, and the other end has a removal key, the first protrusion 1.1.3 is located in the middle of the first buckle 1.1.2, when the ink bag box 1 is installed on the printer, the first protrusion 1.1.3 is deformed under the pressure of the printer, when the first protrusion 1.1.3 enters the first buckle hole 2.8, the first buckle 1.1.2 is reset, so that the first protrusion 1.1.3 is engaged in the first buckle hole 2.8, when the ink bag box 1 needs to be removed, the removal key is pressed to deform the first buckle 1.1.2, the first protrusion 1.1.3 is disengaged from the first buckle hole 2.8, and the ink bag box 1 is taken out;

[0069] It should be noted that the cross-section of the first protrusion 1.1.3 is a right-angled trapezoid. When the ink bag box 1 is installed in the printer, the bevel on the first protrusion 1.1.3 contacts the printer, so that the first buckle 1.1.2 is deformed.

[0070] like Figure 2 and Figure 3 As shown, in one embodiment,

[0071] The ink cartridge 1 comprises:

[0072] The box body 1.1, one end of the first buckle 1.1.2 is arranged on the box body 1.1, the box body 1.1 has a first cavity inside, the box body 1.1 has a plurality of ink outlet holes 1.1.1, and the plurality of ink outlet holes 1.1.1 are all connected to the first cavity;

[0073] A partition is disposed in the box body 1.1, and the first cavity is divided by the partition. The number of the ink outlet holes 1.1.1 is the same as the number of the divided first cavities;

[0074] A plurality of sponges 1.3 are placed in the separated first cavities respectively;

[0075] The box cover 1.2 is detachably connected to the box body 1.1.

[0076] In this embodiment, the partition divides the first cavity in the box body 1.1 into a plurality of small cavities, and each divided small cavity has an ink outlet hole 1.1.1 at the bottom, and each small cavity is provided with a sponge 1.3. When specified ink (e.g., three primary colors or three primary colors plus black, etc.) is added into the box body 1.1, the ink is added into the sponge 1.3 and stored by the sponge 1.3, and the ink in the sponge 1.3 flows out through the ink outlet hole 1.1.1;

[0077] As the ink cartridge 1 is a relatively cheap consumable, when the ink is used up, the ink cartridge 1 can be disassembled and replaced with a new one in the above manner to continue printing. The operation is simple and the user can operate it by himself without training, and there is no need to refill the ink to cause the trouble of spilling the ink.

[0078] like Figure 2 and Figure 3 As shown, in one embodiment,

[0079] The box cover 1.2 is provided with a plurality of small holes, and when the box cover 1.2 and the box body 1.1 are closed, the small holes are communicated with the first cavity.

[0080] In this embodiment, a plurality of small holes are provided on the box cover 1.2, so that the inside of the box body 1.1 is connected with the outside, so as to balance the air pressure inside and outside the box body 1.1 when the ink is consumed during printing.

[0081] like Fig. 9 and Fig.10 As shown, in one embodiment, it also includes:

[0082] The protective cover 4 has a third snap hole 4.2. When the box body 1.1 is not installed on the printer, the first protrusion 1.1.3 is snapped with the third snap hole 4.2 on the protective cover 4;

[0083] Several sealing blocks 4.1 are installed on the protective cover 4. The number of sealing blocks 4.1 corresponds to the number of ink outlet holes 1.1.1. When the box body 1.1 is connected to the protective cover 4, the sealing blocks 4.1 are located in the ink outlet holes 1.1.1.

[0084] In this embodiment, during transportation, the protective cover 4 is engaged with the first buckle 1.1.2 on the box body 1.1 through the third buckle hole 4.2. When the box body 1.1 needs to be installed, the box body 1.1 is separated from the protective cover 4.

[0085] When the box body 1.1 is sold and transported, it is engaged with the protective cover 4 through the first buckle 1.1.2 and the third buckle hole 4.2 on the protective cover 4. The steps of engaging the first buckle 1.1.2 with the third buckle hole 4.2 on the protective cover 4 are the same as the steps of engaging and removing the box body 1.1 and the printer. The first buckle 1.1.2 fastens the third buckle hole 4.2 on the protective cover 4, and at the same time, the sealing block 4.1 is inserted into the ink outlet hole 1.1.1 with interference fit to prevent ink evaporation. The protective cover 4 can be removed by pressing the removal button of the first buckle 1.1.2. The ink in the box body 1.1 is locked by the sponge 1.3, and no ink leakage occurs.
