It is an ink cartridge body having an elliptical opening in the wall. In order to increase the rigidity of the cartridge body, the elliptical peripheral wall can be made into a double layer with a rib 2 connection between the two layers. Two longitudinal partitions 3 are formed in the ink cartridge body 1, and the ink cartridge body 1 is divided into three chambers, a sponge chamber 4 in the middle, and an ink tank 5 on both sides, and a bottom portion opposite to one of the ink tanks 5 is formed with The ink outlet 6 connected to the ink suction port of the printer. A groove 7 is formed in the partition 3 to allow the ink tank 5 to communicate with the sponge chamber 4. At the top of the sponge chamber 4, air inlet holes 8 are connected to connect the sponge chamber 4 to the atmosphere. For easy access, a blade 9 is extended to the both sides of the upper end of the cartridge body 1. On the rear surface of the ink cartridge body 1, an ink injecting hole 10 communicating with the inside of the ink cartridge body 1 is formed, and the ink injecting hole 10 can be blocked by the plug 11 or sealed with a film for adding ink. On the outer wall of the elliptical shape of the ink cartridge body 1, the chip holder 12 and the positioning block 13 are respectively formed on the left and right sides of the ink outlet port 5, and the positioning block 13 is used for positioning on the printer. Locking clasps 14 and tabs 15 are respectively formed on the elliptical outer walls of the left and right sides of the ink cartridge body 1 as connection means fixed to the printer. A groove 16 is formed on the outer surface of the rear side of the cartridge body 1 to allow communication between the sponge cartridge 4 and the ink outlet port 6. A sealing film 17 is adhered to the groove 16 to form an ink supply tube as shown in Fig. 5. The entire cartridge body 1 is shown in Figure 6. An ink absorbing porous sponge 18 is placed in the sponge chamber 4. A plastic sheet 19 is adhered to the outer surface of the opening of the cartridge body 1, so that the cartridge body 1 becomes a sealed container for storing the ink 20. A chip 21 for storing the amount of ink is mounted on the chip carrier 12. At the ink outlet 6 nickel is provided with an ink discharge device that prevents the ink 20 from leaking freely.

在使用中， 带弧形面的墨盒装到打印机上时， 依靠定位块 13在打印机上定位和 锁紧扣 14和杠托 15与打印机固定， 打印机将墨盒内的墨水 20由出墨口 6吸出， 墨 水仓 5的墨水 20经隔板 3上的槽 7进到海绵仓 4内， 再经沟槽 16、 出墨装置到出墨 口 6由打印机吸出实现喷墨打印。 空气由进气孔 8到海绵仓 4内， 使墨盒内的压力 保持平衡。 当墨盒体 1内的墨水 21用完时， 可揭去塞子 11由注墨孔 10向墨盒体 1 内添加墨水 20， 加完后塞上塞子 11， 带弧形面的墨盒又可继续使用了。  In use, when the ink cartridge with the curved surface is attached to the printer, the positioning block 13 is positioned on the printer and the locking buckle 14 and the bar 15 are fixed to the printer, and the printer sucks the ink 20 in the ink cartridge from the ink outlet port 6. The ink 20 of the ink tank 5 enters the sponge chamber 4 through the groove 7 in the partition plate 3, and is sucked out by the printer through the groove 16 and the ink discharging device to the ink outlet port 6 to realize inkjet printing. Air is supplied from the air inlet 8 to the sponge chamber 4 to balance the pressure inside the cartridge. When the ink 21 in the ink cartridge body 1 is used up, the plug 11 can be removed from the ink filling hole 10 to add ink 20 to the ink cartridge body 1. After the filling, the plug 11 is plugged, and the ink cartridge with the curved surface can be used again. .

根据上述椭圆形墨盒体 1 的实施例还可以制造出带圆形面或半圆形面或扇形面 等带弧形面的墨盒体。 隔板 3用一块、 海绵仓 4、 墨水仓 5各一个等形式， 这儿不一 According to the embodiment of the above-described elliptical cartridge body 1, an ink cartridge body having a curved surface such as a circular surface or a semicircular surface or a scalloped surface can be manufactured. The partition 3 is in the form of a piece, a sponge chamber 4, an ink tank 5, etc.
