Detailed ways

The ink cartridge 100 is detachably installed on the main body of the recording device, wherein the ink cartridge installation part on the main body side of the recording device is provided with a sensor composed of a light emitting part and a light receiving part opposite to each other.

Referring to Fig. 1, the ink cartridge 100 includes a box main body 1 with an ink outlet 5, a side sealing film 2, and a conjoined sealing film 3, wherein the conjoined sealing film 3 is used to seal the ink outlet 5 and the air guide hole 4, starting from the ink cartridge 100 Before use, the one-piece sealing film 3 needs to be torn off. The cartridge main body 1 is made of transparent material and includes a frame body 11 and a cover body 12, wherein the space enclosed by the frame body 11 and the cover body 12 can accommodate ink. The ink outlet 5 is arranged on the frame body 11, and a self-closing sealing ring 51 for sealing is arranged therein. The frame body 11 is substantially rectangular, and has a front wall 111 with the ink port 5, a side wall 112 positioned on one side in the width direction of the front wall 111, a top wall 113 and a lower wall 114 positioned on both sides in the height direction of the front wall 111, and The opening on the opposite side of the side wall 112 can be sealed by the cover 12 . The cover body 12 can be installed on the frame body 11 by means of heat welding or the like. An external reflector 6 is installed in a concave portion 1111 on the outer surface of the front wall 111 of the frame body 11 . Corresponding to the outer reflector 6 , an inner reflector 7 is installed on the inner surface of the side wall 112 . Inside the box main body 1, facing the side of the internal reflection surface 71 of the internal reflection member 7, namely between the internal reflection member 7 and the front wall 111, a light-shielding member 8 is installed, which can move up and down in the direction of gravity .

The outer reflector 6 needs to be arranged corresponding to the sensor on the main body side of the recording device, and the inner reflector 7 is arranged parallel to the outer reflector 6 . Referring to Fig. 2 and Fig. 3 together, the external reflector 6 includes two inclined reflective surfaces at a certain angle, which are respectively the first external reflective surface 61 and the second external reflective surface 62, and the angle between them is an obtuse angle; The internal reflection surface 71 of the internal reflection member 7 also includes two inclined reflection surfaces at a certain angle, namely the first internal reflection surface 711 and the second internal reflection surface 712 , and the angle between them is an acute angle. Preferably, the included angle between the first outer reflective surface 61 and the second outer reflective surface 62 is 270°, and the included angle between the first inner reflective surface 711 and the second inner reflective surface 712 is 90°.

When there is ink in the ink cartridge, the shading member 8 can move to between the internal reflection surface 71 of the internal reflection member 7 and the front wall 111 due to buoyancy, as shown in the dotted line in Figure 2, to cover the first internal reflection. surface 711 and the second internal reflection surface 712, at this time, the internal reflection member 7 cannot receive the light from the light-emitting part reflected by the external reflection member 6, so the light-receiving part cannot receive light either. When there is no ink in the ink cartridge, the light-shielding member 8 moves downward in the direction of gravity due to no buoyancy, and moves away from the inner reflection surface 71 of the inner reflection member 7 and the front wall 111, so the light emitted from the light-emitting part can pass through The light path a-b-c-d-e is reflected to the light receiving part, that is, the light emitted from the light emitting part hits the first outer reflective surface 61 of the outer reflector 6, passes through the first inner reflective surface 711 of the inner reflector 7, and the second inner reflector 7 of the inner reflector 7. The inner reflection surface 712 and the second outer reflection surface 62 of the outer reflection member 6 are then reflected to the light receiving part. Accordingly, the presence or absence of ink in the ink cartridge 100 can be detected according to whether the light receiving unit can receive reflected light, and the structure is simple.
