Embodiment 1

[0031] figure 1 Shown is a perspective view of the ink cartridge of the present invention, and the ink cartridge shown in the figure is in the installed state. The direction indicated by the arrow X in the figure is the installation direction of the ink cartridge. The following expressions related to the orientation are all based on the ink cartridge in this state.

[0032] The ink cartridge includes a box body 1, and the box body 1 is formed by fastening a bottom case and a surface cover. The first detection part 10 protrudes from the upper surface 1 a of the ink cartridge, and the front side of the ink cartridge in the installation direction is formed with a deformable cavity 20 , a transparent tube body 30 and an ink supply part 50 . The deformable cavity 20 is arranged in the space formed between the two housings, and can be in contact with the outside world through the through hole on the front side of the ink cartridge. The hole is in contact with the deformable cavity ...

Embodiment 2

[0040] like Figure 7 Shown is a schematic structural diagram of the ink cartridge according to the second embodiment of the invention. In the figure, the mechanism of the face cover is omitted, which can conveniently and intuitively display the internal structural features of the ink cartridge.

[0041] This embodiment cancels the lever 60, the movable part 40 is located in the transparent tube body, and the sealing between the transparent tube body is good, and the transparent tube body is divided into a first tube body 31 and a second tube body 32, the first tube body 31 communicates with the deformable chamber 20 , and the second tube body 32 communicates with the ink storage chamber 70 . In this embodiment, the ink storage chamber 70 can be in any form that does not communicate with the outside atmosphere, and can be the same as the first embodiment. At least one outer wall of the ink storage chamber 70 is made of a deformable film, and can also be different from the embo...

Embodiment 3

[0048] like Figure 12 and Figure 13 Shown is the third embodiment of the present invention, this embodiment cancels the variable cavity, and sets up the channel at the corresponding position, and the projection 82 is set in this channel, when the ink cartridge is installed, the protrusion in the ink cartridge installation part of the printer 104 is in contact with the protrusion 82, and can push the protrusion 82 to move with the installation of the ink cartridge. When the ink cartridge is taken out from the printer, the protrusion 82 can return to its original position under the elastic restoring force of the spring 83. The part of the lower end of the bump 82 in contact with the channel is provided with a magnetic component, for example, a magnetic block 81 is used in this embodiment. The transparent tube body 30 is fixed on the ink cartridge body and separated from the ink storage chamber. The movable part 40 is arranged in the transparent tube body and can move relative...

Abstract

The invention relates to an ink cartridge for an inkjet printer. The ink cartridge comprises an ink cartridge body and an ink storage cavity in the ink cartridge body, wherein ink stored in the ink storage cavity is supplied to the ink outlet of the inkjet printer; the ink cartridge further comprises a detection mechanism for detecting installation of the ink cartridge; the detection mechanism comprises a first detection portion for shielding or changing a first sensor signal path on the inkjet printer, and a second detection part for selectively shielding or changing a second sensor signal path on the inkjet printer; the second detection part comprises a contact mechanism of which one end can contact the bulge on the installation part of the ink cartridge for the inkjet printer, a transparent tube and a movable component in the transparent tube; the movable component can be driven under deformation or movement of the contact mechanism, so that the ink cartridge can be detected during installation. The detection mechanism is simple and easy to assemble, and ink adhesion avoided to further guarantee the detection precision.

Description

technical field [0001] The invention relates to an ink cartridge for an ink jet printer. Background technique [0002] The ink cartridge used with an inkjet printer mainly includes an ink storage chamber for storing ink, an ink outlet for supplying ink to the print head of the printer, and a detection component for detecting whether the ink cartridge is installed and detecting the remaining amount of ink in the ink cartridge . In order to ensure that the ink cartridge can work normally after being loaded into the printer, the ink cartridge must contain these two detection mechanisms. The receiving part of the second sensor, along with the installation, the light emitted by the second sensor emitting part can return to the receiving part of the second sensor, and then another detection mechanism prevents the light emitted by the first sensor emitting part from returning to the first sensor. The receiving part of the sensor, and finally, the light emitted by the correspondin...
