FIG. 1 is a schematic diagram of an exemplary embodiment of a sealing cap 100 for an ink cartridge; FIG. 2 is a schematic view of an ink cartridge provided in one embodiment; fig. 3 is a schematic structural view of an ink cartridge body provided in one embodiment. Referring to fig. 1 to 3, a fixing portion 110 to accommodate an external cartridge is formed on the cartridge sealing cover 100.

The external cartridge body 200 is provided with an ink outlet 212 and an air vent 221, and in order to ensure that the ink in the cartridge does not leak during transportation, the ink outlet 212 and the air vent 221 on the external cartridge body are sealed by the cartridge sealing cover 100 before use. When the ink cartridge is in operation, the ink supply process needs to exchange gas and liquid, so the ink outlet 212 and the air vent 221 need to be in an open state.

The cartridge sealing cover 100 is a frame body that can accommodate a part of the cartridge body, and the frame body includes a bottom surface 120 and a fixing portion 110 connected to one end of the bottom surface 120. The fixing portion 110 formed on the cartridge sealing cover 100 is provided with a protrusion 111, and the protrusion 111 is matched with the air guide hole 221 of the external cartridge for sealing the air guide hole 221 of the external cartridge. It is understood that the fixing portion 110 is also used to fixedly connect the cartridge sealing cover 110 to the cartridge body 200. Specifically, in the present embodiment, the ink outlet 212 is opened on the first surface 210 of the ink cartridge body 200, and the air vent 221 is opened on the second surface 220 of the ink cartridge body. In a state where the cartridge sealing cover 100 seals the cartridge body 200, the bottom surface 120 of the cartridge sealing cover 100 corresponds to the first surface 210 of the cartridge, and the fixing portion 110 of the cartridge sealing cover 100 corresponds to the second surface 220 of the cartridge body, i.e., in a sealed state, the bottom surface 120 and the fixing portion 110 of the cartridge sealing cover 100 are not on the same plane.

The ink cartridge is supplied to the printer with gas-liquid exchange, so that the air vent 221 and the ink outlet 212 are open when the ink cartridge is in operation. In order to ensure that the ink does not leak during the transportation of the ink cartridge, a sealing film or a cartridge sealing cap 100 is attached to the air vent 221 and the ink outlet 212. The transportation process and the environmental influence may change the gas-liquid environment inside the ink cartridge, and the ink may overflow or splash when the air vent 221 and the ink outlet 212 are opened, so the sequence and operation of removing the cartridge sealing cover 100 are very important.

In this embodiment, when the user needs to open the cartridge sealing cap 100, the fixing portion 110 is first opened to open the air vent 221 of the cartridge body 200. At this time, if the pressure inside the ink cartridge is greater than the pressure outside the ink cartridge, the excess gas inside the ink cartridge may be discharged from the gas vent 221 (for example, due to temperature increase, accelerated movement of the portion caused by severe shaking during transportation of the ink cartridge, or other factors that may cause the gas inside the ink cartridge to expand); then, the user continues to open the cartridge sealing cover 100 to open the ink outlet 212 on the first surface 210 of the cartridge body, and if the ink outlet 212 has residual ink (for example, ink is gathered at the ink outlet due to ink gravity, etc.), the residual ink can be absorbed by unsaturated sponge, so that ink dripping or residual ink at the ink outlet 212 can be avoided.

The ink cartridge sealing cover 100 provided by the embodiment has a fixing portion 110 formed thereon for fitting the external ink cartridge, and the fixing portion 110 is provided with a protrusion 111, and the protrusion 111 is matched with the air vent 221 of the external ink cartridge body 200. When the user removes the cartridge sealing cover 100, the fixing portion 110 may be opened first to allow the air vent 221 of the external cartridge body 200 to be opened preferentially. Then, the cartridge sealing cap 100 is continuously removed to delay the opening of the ink outlet 212, so that the pressure balance between the gas and the liquid in the cartridge body 200 can be ensured, and the ink can be prevented from overflowing or splashing. In addition, the ink cartridge sealing cover 100 is designed as an integral type, and a user can complete two functions by one action, namely opening the air vent 221 and the ink outlet 212 in a time-sharing manner, so that the user experience is improved.

In one embodiment, the cartridge sealing cover further includes a side wing, the fixing portion 110 is connected to the bottom surface 120, a gasket mounting portion 121 is disposed on the bottom surface 120, and the gasket mounting portion 121 matches with the external cartridge body ink outlet 212; the side wings far away from the fixing part 110 are provided with buckles.

The bottom surface 120 of the cartridge sealing cover 100 is provided with a gasket mounting position 121, and a gasket 211 matched with the size of the ink outlet 212 can be mounted on the gasket mounting position 121 to seal the ink outlet 212. The gasket 211 may be made of an elastic material or other materials, and the specific material of the gasket 211 is not limited in this embodiment.

In one embodiment, the periphery of the gasket 211 is provided with protrusions. During printing, because the ink is usually concentrated at the position of the ink outlet 212, when the ink outlet 212 is opened, the ink is easy to remain at the ink outlet 212, most of the redundant ink can be absorbed by the sponge, and the ink adhered to the sealing gasket can be limited in the convex gap of the sealing gasket, so that the phenomenon of ink drop flowing can not be generated, and unnecessary pollution is avoided.

In one embodiment, the cartridge sealing cover further includes two side wings, a first side wing 131 and a second side wing 132. The two side wings are perpendicular to the bottom wall of the ink box sealing cover, far away from the fixing part 110 and provided with buckles, and are used for being clamped into clamping grooves corresponding to the ink box body.

FIG. 2 is a schematic view of an ink cartridge 10 according to an embodiment, in which the ink cartridge 10 includes a cartridge body 200 and a cartridge sealing cap 100, as shown in FIG. 2;

referring to fig. 1 and 3, the ink cartridge body 200 may include an ink storage chamber, a sponge chamber, and an air guide chamber, the ink storage chamber and the sponge chamber are communicated through an air-liquid passage, the air guide chamber and the sponge chamber are communicated through an air passage, the ink outlet 212 may be opened at the bottom of the sponge chamber, and the ink storage chamber is used for storing ink. The ink storage cavity and the sponge cavity which are communicated can enable ink to be supplied more stably, and preferably, the sponge cavity can be internally provided with a plurality of sponges with different densities so as to better control the flow of ink.

The cartridge sealing cover 100 is formed with a fixing portion 110 adapted to an external cartridge; the fixing portion 110 is provided with a protrusion 111, and the protrusion 111 is matched with the air vent 221 of the external ink box.

The external ink box is provided with an ink outlet 212 and an air guide hole 221, and in order to ensure that the ink in the ink box does not leak in the transportation process, the ink outlet 212 and the air guide hole 221 on the external ink box are sealed by the ink box sealing cover 100 before use. When the ink cartridge is in operation, the ink supply process needs to exchange gas and liquid, so the ink outlet 212 and the air vent 221 need to be in an open state.

The cartridge sealing cover 100 is a frame body that can accommodate a part of the cartridge body, and the frame body includes a bottom surface 120 and a fixing portion 110 connected to one end of the bottom surface 120. Wherein, a sealing gasket mounting position 121 is arranged at the position of the bottom surface 120 corresponding to the ink outlet 212; the fixing portion 110 formed on the cartridge sealing cover 100 is provided with a protrusion 111, and the protrusion 111 is matched with the air guide hole 221 of the external cartridge for sealing the air guide hole 221 of the external cartridge. It is understood that the fixing portion 110 is also used to fixedly connect the cartridge sealing cover 110 to the cartridge body 200. Specifically, in the present embodiment, the ink outlet 212 is formed on the first surface 210 of the ink cartridge body 200, and the air vent 221 is formed on the second surface 220 of the ink cartridge body. In a state where the cartridge sealing cover 100 seals the external cartridge body 200, the bottom surface 120 of the cartridge sealing cover 100 corresponds to the first surface 210 of the cartridge, and the fixing portion 110 of the cartridge sealing cover 100 corresponds to the second surface 220 of the cartridge body, i.e., in a sealed state, the bottom surface 120 and the fixing portion 110 of the cartridge sealing cover 100 are not on the same plane.

The bottom surface 120 of the ink box sealing cover is provided with a sealing gasket mounting position 121, and a sealing gasket 211 matched with the size of the ink outlet 212 can be mounted on the sealing gasket mounting position 121 to seal the ink outlet 212. The gasket 211 may be made of an elastic material or other materials, and the specific material of the gasket 211 is not limited in this embodiment.

In one embodiment, the cartridge sealing cap 100 further includes two side wings, a first side wing 131 and a second side wing 132. The two side wings are perpendicular to the bottom wall of the ink box sealing cover, far away from the fixing part 110 and provided with buckles, and are used for being clamped into clamping grooves corresponding to the ink box body.

In one embodiment, a packing mounting position 223 is formed along the circumferential direction of the air guide hole. The seal ring mounting location 223 may be used to mount a seal ring (not shown). The packing may be inserted into the packing installation position 223, and the protrusion 111 of the cartridge sealing cover 100 seals the air guide hole 221 through the packing. In this embodiment, the sealing ring is installed in the sealing ring installation position 223 above the air vent 221, and the protrusion 111 of the cartridge sealing cover 100 abuts against the sealing ring to seal the air vent 221, so as to achieve a better sealing effect. In addition, the sealing ring for sealing the air guide hole 221 and the sealing gasket 211 for sealing the ink outlet 212 are independent from each other, have no directionality, and are easier and more convenient to assemble.

In an embodiment, the protrusion 111 may be a hemisphere, and accordingly, the sealing ring may be a cylindrical structure, and two circular end surfaces of the sealing ring are recessed to accommodate the hemisphere protrusion 111, so that the protrusion 111 can provide a stable pressure to the sealing ring. Specifically, when the fixing portion 110 is clamped to the second surface 220 of the ink cartridge body, the protrusion 111 on the fixing portion 110 is embedded in the concave end surface of the sealing ring, so that the acting position of the protrusion 111 is closer to the air guide hole 221, and a larger supporting force can be stably provided for the sealing ring, so that the sealing ring is tightly attached to the air guide hole 221, and a better sealing effect is achieved.

In one embodiment, the inner diameter of the sealing ring is matched to the diameter of the gas guide 221 hole, the inner diameter of the sealing ring is smaller than the hemispherical diameter of the protrusion 111, and the outer diameter of the sealing ring is larger than the hemispherical diameter of the protrusion 111. The inner diameter of the sealing ring and the diameter of the air guide hole 221 are only required to meet the requirement that the sealing ring and the air guide hole 221 can be in smooth butt joint, and the specific numerical value is not limited in this embodiment. The air guide hole 221 can be sealed more tightly by reasonably setting the inner diameter and the outer diameter of the sealing ring.

The ink cartridge is generally provided with an ink inlet, an ink outlet 212, and an air vent 221 in order to perform canning during processing and exchange of air and liquid during operation. The existing sealing method mainly utilizes the pressure generated when the rubber pieces are clamped to each other, and the ribs protruding around the openings of the rubber pieces are pressed against the soft sealing gaskets. However, when the pressing force is not uniform, the flexible gasket is easily deformed, resulting in a failure of sealing. The present embodiment utilizes different sealing principles to respectively seal the ink outlet 212 and the air vent 221. Specifically, the matched protrusion 111 and the air guide hole 221 with the smaller sealing area of the sealing ring are adopted, and the ink outlet 212 with the larger area is sealed by the sealing gasket 211, so that the best sealing effect is realized.

In one embodiment, the second surface 220 of the ink cartridge body is provided with a first latch 222, and the first latch 222 matches with the first slot 112 provided on the fixing portion 110 of the ink cartridge sealing cover 100. Specifically, the first fasteners 222 are located above the sealing ring mounting locations 223 and symmetrically disposed on two sides of the sealing ring mounting locations 223, the fixing portion 110 of the ink cartridge sealing cover 100 is provided with a first engaging groove 112 matched with the first fasteners 222, and the fixing portion 110 is fixedly connected to the ink cartridge body 200 by engaging the first fasteners 222 with the first engaging groove 112, so that the fixing portion 110 seals the air guide hole 221.

In an embodiment, a groove 224 is formed on the first latch 222, and after the first latch 222 is latched with the first latch groove 112, the first latch 222 can be embedded in the groove to better seal the ink cartridge 100 and the ink cartridge body 200.

In one embodiment, a second locking groove 231 is formed on a fourth surface of the cartridge body opposite to the third surface 230, and the second locking groove 231 matches with the second locking buckle 133 formed on the lateral wing of the cartridge sealing cover 100. The bottom 120 of the cartridge sealing cover 100 is connected to the cartridge body 200 by the second latch 133 engaging with the second slot 231, so that the sealing pad 211 on the bottom of the cartridge sealing cover 100 seals the ink outlet 212.

When the user opens the ink cartridge sealing cover 100, the user firstly pokes the fixing part 110 of the ink cartridge sealing cover 100 to make the first buckle 222 separate from the first clamping groove 112, so that the air vent 221 can be in an open state; at this time, if the pressure inside the ink cartridge is greater than the pressure outside the ink cartridge, the excess gas inside the ink cartridge may be discharged from the gas vent (for example, due to temperature rise, accelerated movement of the portion caused by severe shaking during transportation of the ink cartridge, or other factors that may cause the gas inside the ink cartridge to expand); then, the user continues to move the cartridge sealing cover 100 to disengage the second latch 133 from the second latch slot 231, so that the ink outlet 212 on the first surface of the cartridge body 200 can be opened. If the ink outlet 212 has residual ink (for example, the ink is gathered at the ink outlet due to the gravity of the ink, etc.), the residual ink can be absorbed by the unsaturated sponge, so as to avoid the ink dripping or residual ink from the ink outlet 212.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
