Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a perspective view of an ink cartridge according to the present invention; fig. 2 is a partially exploded perspective view of the ink cartridge according to the present invention, as viewed from another angle. FIG. 3 is a side view of the ink cartridge according to the present invention, viewed in a direction perpendicular to the center line of the communicating holes of the two chambers; fig. 4 is a sectional view taken along a plane parallel to the center line of the communication holes of the two chambers in the ink cartridge according to the present invention.
The ink box 1 comprises a shell 11 and an ink outlet 12 arranged on the shell 11, the shell encloses to form a cavity for containing ink, the cavity is divided into a first cavity 13 directly communicated with the ink outlet 12 and a second cavity 14 not directly connected with the ink outlet 12 by a partition plate 15 arranged in the shell, a communication hole 2 is arranged on the partition plate 15, the first cavity 13 is communicated with the second cavity 14 through the communication hole 2, and the side of the partition plate 15 facing the first cavity 13 is a first side 15a, and the side facing the second cavity 14 is a second side 15 b; further, the ink cartridge 1 further includes a check valve installed on the communication hole 2, and when the ink in the first chamber 13 is consumed, the check valve allows the ink in the second chamber 14 to be replenished to the first chamber 13 through the communication hole 2, but does not allow the ink in the first chamber 13 to flow back to the second chamber 14 through the communication hole 2.
As shown in fig. 4, the communication hole 2 has a center line L, when the ink cartridge 1 is mounted to the inkjet image forming apparatus and starts to operate, the ink in the second chamber 14 is replenished to the first chamber 13 through the communication hole 2 in a direction parallel to the center line L, and at the initial stage when the ink cartridge starts to be used, the entire gravity of the ink in the second chamber 14 will be directly exerted on the communication hole 2, and at this time, even if the ink in the first chamber 13 is not consumed, the gravity of the ink in the second chamber 14 may push the check valve open, causing the ink in the second chamber 14 to have a tendency to flow toward the first chamber 13, and further causing the pressure of the ink outlet 12 to increase.
Therefore, the ink cartridge 1 of the present invention further includes a diversion portion 3 disposed on the partition 15 and a covering member 4 covering the diversion portion 3, wherein the diversion portion 3 is disposed on the second side 15b of the partition and is communicated with the second cavity 14 and the communication hole 2. As a whole, the flow guide 3 is formed by ribs protruding from the second side 15b toward the second cavity 14, and includes a first flow channel 31 communicating with the communication hole 2, a second flow channel 32 communicating with the first flow channel 31, and an opening 33 at an end of the second flow channel 32, and the flow guide 3 communicates with the second cavity 14 through the opening 33.
When the ink in the first chamber 13 is consumed, as shown in fig. 3, the ink in the second chamber 14 enters the flow guide portion 3 through the opening 33, and flows from the second flow channel 32 to the first flow channel 31 in the direction indicated by the arrow in the figure, and further reaches the communication hole 2. The cover 4 covers the entire flow guide 3 except for the opening 33, so that the cover 4 and the flow guide 3 form an isolated cavity in the second cavity 14, and the volume of the isolated cavity is much smaller than that of the second cavity 14. As shown in fig. 4, along the central line L of the communication hole 2, the height of the flow guiding part 3 is h2, the height of the second cavity 14 is h1, h1 is much larger than h2, in the second cavity 14, due to the isolation of the cover 4, the gravity of the ink applied to the communication hole 2 is reduced from all the original ink in the second cavity 14 to only the ink in the flow guiding part 3, at this time, the gravity of the ink applied to the communication hole 2 is greatly reduced, and the check valve is not pushed open under the gravity of the ink in the second cavity 14.
As described above, the utility model relates to an ink cartridge 1 sets up one in second cavity 14 can with the intercommunication hole and the equal isolation chamber that communicates of second cavity for direct ink volume that exerts the action of gravity to intercommunication hole 2 reduces in the second cavity 14 through this isolation chamber, thereby reaches the purpose that prevents the ink of ink cartridge when not using and reveals.
Based on this, only the first flow channel 31 communicating with the communication hole 2 may be provided in the guide portion 3, in which case the opening 33 is located at the end of the first flow channel 31, the cover 4 covers the first flow channel 31, and the first flow channel 31 communicates with the second chamber 14 through the opening 33, and this structure can also achieve a reduction in the amount of ink applied to the communication hole 2 by gravity; in view of delaying the flow rate of ink, it is preferable to provide the second flow path 32 or more flow paths communicating with the second flow path 32.
Further, the flow guide portion 3 may be formed in a form such that, in addition to the ribs extending from the second side 15b to the second cavity 14, for example, a hollow tube extending from the second side 15b to the second cavity 14 in a direction parallel to the center line L, an end of the hollow tube is covered with the cover 4, and a portion of the hollow tube between the communication hole and the cover 4 is opened to achieve communication between the hollow tube 4 and the second cavity 14, and the hollow tube covered with the cover 4 may also be regarded as the above-described isolation cavity.
