[0031] Referring Figure 2 As shown, the chip component 3 includes a chip carrier part 31 and a chip 32. The chip carrier part 31 is disposed on the chip mounting part 2, and the chip carrier part 31 is provided with a first area and a second area. The thickness of the first area of the chip carrier part 31 is less than the thickness of the second area. The chip 32 is mounted on the first area, and the chip 32 is used to store information such as the manufacturer information of the ink cartridge, the ink volume information, the consumable cartridge type information, and the ink color.

[0032] Referring Figure 3As shown, the housing 1 has a rectangular structure, which has a bottom end face 12, a top end face 11, a first side end face 13, a second side end face 14, a third side end face 15 and a fourth side end face 16. The bottom end face 12 and the top end face 11 are oppositely arranged, the first side end face 13 and the second side end face 14 are oppositely arranged, and the third side end face 15 and the fourth side end face 16 are oppositely arranged. Among them, the bottom end face 12 constitutes the insertion direction side where the ink cartridge is inserted into the printer installation part. The chip installation part 2 and the ink outlet 17 are respectively located at both ends of the bottom end face 12. Exemplarily, the ink outlet 17 is closer to the second side end face 14 than the chip installation part 2, and the chip installation part 2 is closer to the first side end face 13 than the ink outlet 17. The handle part 4 is inclined and arranged on the first side end face 13, the first engaging part 5 protrudes from the handle part 4, the second engaging part 6 protrudes from the second side end face 14, and the second engaging part 6 is closer to the ink outlet 17 than the handle part 4. When the ink cartridge 100 is installed on the printer, the handle part 4 is engaged with the printer, and the second engaging part 6 is also engaged with the printer. Thus, under the action of the first engaging part 5 and the second engaging part 6, the ink cartridge 20 can be stably fixed on the printer to realize ink filling.

[0033] Referring to Figure 4 As shown, the chip installation part 2 includes a fixing part 21 and a positioning and engaging part 22. The fixing part 21 is at least partially formed by recessing from the bottom end face 12, and the distance from the end of the fixing part 21 away from the ink outlet 17 to the top end face 11 is less than the distance from the end of the fixing part 21 close to the ink outlet 17 to the top end face 11. The positioning and engaging part 22 is arranged on the bottom end face 12 and is located at the end of the fixing part 21 away from the ink outlet 17, that is, the positioning and engaging part 22 is farther from the ink outlet 17 than the fixing part 21, and the positioning and engaging part 22 is used to limit the chip component 3.

[0034] The structural design of the chip installation part 2 in this embodiment enables the removed chip component 3 to match with it, which is convenient for installation, so that the chip component 3 can be reasonably used. At the same time, in the present application, by making at least part of the fixing part 21 a recessed structure, it is possible to prevent part of the structure of the fixing part 21 from being damaged when the ink cartridge drops. Also, since the distance from the end of the fixing part 21 away from the ink outlet 17 to the top end face 11 is less than the distance from the end of the fixing part 21 close to the ink outlet 17 to the top end face 11, when the ink cartridge 100 is inserted into the printer installation part in the insertion direction, it can correctly guide the positioning, engagement and fixation of the chip component 3 to improve the user experience and save resources and costs.

[0035] Continue to refer to Figure 4As shown, the positioning and engaging portion 22 includes a positioning recess 221 and a limiting portion 222. The limiting portion 222 is connected to the housing 1 and is located at one end of the fixing portion 21 away from the ink outlet 17. The limiting portion 222 is used to limit the movement of the chip carrier portion 31. The positioning recess 221 is provided on the bottom end surface 12 and is located between the limiting portion 222 and the fixing portion 21, and is used to mount at least part of the chip carrier portion 31 that does not carry the chip 32.

[0036] In this embodiment, the limiting portion 222 encloses three sides of the positioning recess 221 and is connected to the second side end surface 14, the third side end surface 15, and the fourth side end surface 16, forming a three-sided enclosure. In other embodiments, the limiting portion 222 may also be provided only on one side of the positioning recess 221 away from the ink outlet 17, such as Figure 5 and Figure 6 shown.

[0037] In some embodiments, the positioning recess 221 may not be provided, but instead the limiting portion 222 may be directly provided. Or, the positioning recess 221 may also be formed by the depression of the fixing portion 21.

[0038] In this embodiment, the fixing portion 21 includes a fixing surface and an adhesive layer. The fixing surface is set as an inclined surface, and the distance between the inclined surface and the plane of the bottom end surface 12 gradually decreases from the end away from the ink outlet 17 to the end close to the ink outlet 17. The adhesive layer is pasted on the inclined surface to paste at least part of the chip carrier portion 31 on the fixing portion 21 through the adhesive layer. Among them, the adhesive layer may be formed by coating the fixing surface with a fixing glue. The fixing glue may be a double-sided adhesive or other glues that meet the above pasting method.

[0039] In some embodiments, the fixing surface may also be set as a horizontal plane, the adhesive layer is pasted on the horizontal plane, and the thickness of the end of the adhesive layer away from the ink outlet 17 is less than the thickness of the end of the adhesive layer close to the ink outlet 17, so that the distance between the end of the fixing portion 21 close to the ink outlet 17 and the upper end surface 11 is greater than the distance between the end of the fixing portion 21 away from the ink outlet 17 and the upper end surface 11.

[0040] In order to facilitate the removal of the chip assembly 3 when disassembling the chip assembly 3, the chip mounting portion 2 further includes a removal portion 23. The removal portion 23 is located on both sides of the fixing portion 21, that is, the removal portion 23 is located on the third side end surface 15 and the fourth side end surface 16, and the distance between the end surface of the removal portion 23 and the plane of the bottom end surface 12 is greater than the distance between the fixing surface and the plane of the bottom end surface 12. Thus, through the setting of the removal portion 23, it is convenient to remove the used chip assembly 3 from the chip mounting portion 2.

[0041] As described above, it is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application.
