The air guide hole 32 is used for guiding out the air in the ink bag, the air guide hole 32 is communicated with the inside of the ink bag shell 2, and then air pressure between the ink bag shell 2 and the external environment is balanced, so that the ink can smoothly flow out, and meanwhile, the ink in the ink bag shell 2 is prevented from drying due to air evaporation by guiding out the air in the ink bag shell 2. Alternatively, the air holes 32 may be circular or square as long as they communicate with each other.

Annotate inside the china ink hole 34 can communicate the china ink bag casing 2 for toward the inside ink that injects of china ink bag casing 2, through annotating the inside ink that injects of china ink hole 34 to the china ink bag casing 2, easy operation is convenient. The number of the ink injection holes 34 and the air guide holes 32 is related to the type of the ink cartridge, for example, if the ink cartridge is a monochrome ink cartridge, the ink injection holes 34 and the air guide holes 32 are each provided as one; if the ink cartridge is a multi-color ink cartridge, there may be one ink injection hole 34 and one air guide hole 32 according to the color, each ink injection hole 34 is used for injecting ink of one color, and each air guide hole 32 is used for communicating with the chamber in which the ink of one color is located.

As shown in fig. 7-10, the window 12 may alternatively be located at a middle position of the outer wall of the print head housing 1, the first region 111 is located below the window 12, and the second chip 21 is located above the window 12 relative to the window 12, so that the first chip 11 extends upward from the first region 111 to the position of the window 12, then bends upward after passing through the window 12 into the print head housing 1, and extends to the second chip 21, so that the second region 112 can be electrically connected to the second chip 21 in a contacting manner, and the second region 112 is located above the window 12 in the vertical direction. It is also possible that the window 12 is located in the middle of the outer wall of the printhead housing 1, the first region 111 and the second die 21 are both located below the window 12, and the first die 11 extends through the window 12 into the printhead housing 1 and then bends downward to the second die 21, i.e. in the vertical direction, the second region 112 is located below the window 12.

Alternatively, the window 12 may be located at a position close to the lower part of the outer wall of the print head housing 1, the first region 111 is located above the window 12, and the second chip 21 is located above the window 12 relative to the window 12, so that the first chip 11 extends downward from the first region 111 to the position of the window 12, then bends upward to the second chip 21 after entering the interior of the print head housing 1 through the window 12, and the second region 112 can be electrically connected to the second chip 21 in contact, i.e., in the vertical direction, above the window 12.

In the above-mentioned multiple arrangement modes, the position of the window 12 and the position of the second region 112 in the vertical direction are always deviated, the first chip 11 needs to be bent (upward or downward) after entering the window 12 to enable the second region 112 to reach the second chip 21, and because the position of the window 12 is located between the upper end portion and the lower end portion of the outer wall of the print head housing 1, the bent position of the first chip 11 is also always located between the upper end portion and the lower end portion of the outer wall; the arrangement mode can enable the first chip 11 to be mounted on the printing head shell 1 more simply and stably, and the first chip 11 and the second chip 21 are connected in place in the second area 112 through the positioning of the window 12 and the fixing of the window and the inner ink bag shell 2, so that the contact is good; the requirement on the recovery process of the recovered ink box is reduced, and compared with the situation that the connecting holes in the prior art need to be aligned with the holes at the positions of the inner contacts, the recovery cost is reduced.

The first region 111 and the second region 112 are connected to form the first chip 11, and the first chip 11 may be a split type or an integrated type. When the first chip 11 is split, the first region 111 and the second region 112 may be connected by soldering or bonding; when the first chip 11 is a single body, the first region 111 and the second region 112 may be connected by an integral molding.

Alternatively, the portion of the first chip 11 penetrating through the window 12 may be configured as a circular arc shape, or may be a prism shape with a chamfer, so as to facilitate the first chip 11 to be wound around the edge of the window 12, and at the same time, avoid the sharp edge of the window 12 from damaging the second region 112, which results in the failure of electrical connection.

During printing, the first chip 11 is positioned on the head housing 1 and the second chip 21 is positioned on the ink bag housing 2, and when the ink bag is assembled to the head housing 1, the second chip 21 is in contact with the first chip 11 (the second region 112 of the first chip 11 is in contact with the second chip 21) and the first chip 11 is in contact with the printer.

When printing, the printer sends an instruction for reading the ink amount, the second chip 21 and the first chip 11 receive the instruction of the printer at the same time, at the moment, the second chip 21 feeds back the ink amount information to the printer, the first chip 11 feeds back the information that the residual ink amount in the ink box is 0 to the printer, and at the moment, the printer receives the superposed signal of the two chips, namely, the superposed signal is identified as the required ink amount information.

The printer acquires the ink information stored in the second chip 21 through the first chip 11 and the second chip 21, calculates the ink consumption according to the printing condition, further obtains the residual ink amount in the ink bag shell 2, and stores the residual ink amount in the second chip 21; after the printer reads the information that the ink amount is 0, the printer prompts that the ink is exhausted, and prompts a user to replace the ink box, at the moment, only the ink bag in the printer needs to be replaced, the printing head shell 1 is repeatedly used, resources are saved, and environmental pollution is avoided.

The method can obtain the actual ink amount in the ink bag, and prevent the problems of ink waste, damage to the printing head due to idle printing or line breakage during printing. It should be understood by those skilled in the art that after receiving the command from the printer, the second chip 21 may directly feed back the ink amount information to the printer. In addition, it should be understood by those skilled in the art that the first chip 11 and the second chip 21 can respond to various commands of the printer respectively, or can cooperate with each other to respond to commands of the printer.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
