[0002] An ink cartridge is a component used to store printing ink in an inkjet printer. The ink cartridge has a liquid injection port through which ink can be injected into the ink cartridge. The print head of the inkjet printer can eject the ink supplied by the ink cartridge onto the printing medium to form the text or pattern to be printed on the printing medium.

[0003] In the related art, an electrolyte is added to the ink so that the ink can conduct electricity. Whether there is ink in the ink cartridge is directly detected by two probes, that is, if the two probes are conducted, there is ink, and if the two probes are not conducted, the ink level is too low.

[0004] However, in order to avoid the corrosion of the print head and the clogging of the nozzles caused by the electrolyte, no electrolyte is added to the ink, resulting in the inkjet printer being unable to detect whether there is ink in the ink cartridge. Summary of the Utility Model

[0051] As described in the background art, in order to avoid the corrosion of the print head by the electrolyte and the clogging of the nozzles, the ink does not contain electrolyte, resulting in the inkjet printer being unable to detect whether there is ink in the ink cartridge.

[0052] To solve the above problems, the embodiments of the present utility model provide a liquid container and a printer, which are provided with a conductive member. When the conductive member contacts the probe assembly, the probe assembly is turned on, indicating that there is ink.

Thus, when the ink does not contain electrolyte, the printer can detect whether there is ink in the liquid container, ensuring the normal use of the printer; or, when the conductive member is separated from the probe assembly, the probe assembly is not turned on, indicating that there is ink. When the conductive member contacts the probe assembly, the probe assembly is turned on, indicating that the ink level is too low.

[0053] The following will describe in detail the liquid container and the printer provided by the embodiments of the present utility model in conjunction with specific embodiments.

[0054] See Figure 1 As shown, the embodiments of the present utility model provide a printer, which includes a frame body 10, a rail shaft 11, and an ink carriage 12.

[0055] The rail shaft 11 is fixed on the frame body 10. The ink carriage 12 is in sliding contact with the rail shaft 11. The ink carriage 12 slides along the rail shaft 11 through a motor and a belt.

[0056] The printer further includes a liquid container 20 and an ink supply tube 13. The liquid container 20 is detachably mounted on the frame body 10. One end of the ink supply tube 13 is connected to the liquid container 20, and the other end is connected to the ink carriage 12.

[0057] A print head is mounted on the ink carriage 12. The print head sprays the ink supplied by the liquid container 20 onto the print medium to form the text or pattern to be printed on the print medium. In some examples, the print medium is paper.

[0058] The printer further includes a position coding strip 14. The position coding strip 14 is mounted on the frame body 10. A sensor is provided on the ink carriage 12, and the position of the ink carriage 12 is detected through the sensor and the position coding strip 14.

[0059] The printer further includes a paper tray 15, a paper feed roller 16, and a paper output roller 17.

[0060] The paper tray 15 is used to place multiple stacked sheets of paper. The paper is sent under the print head through the paper feed roller 16. The ink carriage 12 is driven to slide along the rail shaft 11 through a motor and a belt, and the print head slides along the rail shaft 11 with the ink carriage 12. The print head sprays ink, thereby forming the text or pattern to be printed on the paper. When printing is completed, the paper with the formed text or pattern is conveyed to the outside of the printer by the paper output roller 17.

[0061] See Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a liquid container 20, including a container body 21 and an ink detection mechanism 22; the ink detection mechanism 22 is provided on the container body 21. The ink detection mechanism 22 is used to detect whether there is ink in the liquid container 20.

[0062] The container body 21 has an ink storage cavity 211. The ink storage cavity 211 stores ink.

[0063] The container body 21 has a top wall 21a and a bottom wall 21b, and the top wall 21a and the bottom wall 21b are oppositely arranged in the height direction of the liquid container 20.

[0064] The container body 21 has a front wall 21c and a rear wall 21d, and the front wall 21c and the rear wall 21d are oppositely arranged in the length direction of the liquid container 20.

[0065] The container body 21 has a left wall 21e and a right wall 21f (see Figure 5 shown), and the left wall 21e and the right wall 21f are oppositely arranged in the width direction of the liquid container 20.

[0066] The container body 21 has an ink filling port 212. Ink can be injected into the ink storage chamber 211 through the ink filling port 212.

[0067] A coordinate system is established for the liquid container 20. The X-axis direction is the length direction of the liquid container 20, the Y-axis direction is the width direction of the liquid container 20, and the Z-axis direction is the height direction of the liquid container 20. The X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0068] The first direction is the height direction of the liquid container 20. The second direction is the width direction of the liquid container 20. The third direction is the length direction of the liquid container 20.

[0069] See Figure 2 and Figure 3 As shown in

[0070] The frame body 221 is connected to the container body 21. In some examples, the frame body 221 can be connected to the front wall 21c of the container body 21. The frame body 221 can be integrally formed with the container body 21. Or, the frame body 221 can also be adhesively connected to the container body 21. Or, the frame body 221 can also be welded to the container body 21.

[0071] The frame body 221 and the container body 21 can enclose a cavity 2211. Or, in other embodiments, the frame body 221 can also have a cavity 2211 inside.

[0072] The cavity 2211 communicates with the ink storage chamber 211. The ink in the ink storage chamber 211 can enter the cavity 2211.

[0073] In the first direction, the frame body 221 is closer to the bottom wall 21b of the container body 21 than the top wall 21a of the container body 21.

[0074] At least part of the probe assembly extends into the cavity 2211. The probe assembly includes two probes 223, and the two probes 223 are connected to the front wall 21c of the container body 21. The two probes 223 partially extend into the cavity 2211, and the two probes 223 are arranged in sequence along the second direction perpendicular to the height direction of the liquid container 20.

[0075] Both of the two probes 223 extend along the length direction of the liquid container 20. The two probes 223 are connected to the control main board of the printer.

[0076] In this embodiment, when the two probes 223 are conducting, the printer can determine that there is ink in the liquid container 20, enabling the printer to operate normally. When the two probes 223 are not conducting, that is, when the two probes 223 are disconnected, the printer can determine that the ink level in the liquid container 20 is too low (no ink or little remaining ink), the ink level in the ink storage chamber 211 is in an alarm state, and the printer can only operate normally after the liquid container 20 is replenished with ink. In other embodiments, when the two probes 223 are conducting, the printer can also determine that the ink level in the liquid container 20 is too low (no ink or little remaining ink), the ink level in the ink storage chamber 211 is in an alarm state, and the printer can only operate normally after the liquid container 20 is replenished with ink. When the two probes 223 are not conducting, that is, when the two probes 223 are disconnected, the printer can also determine that there is ink in the liquid container 20, enabling the printer to operate normally.

[0077] The conductive member 222 is movably disposed in the cavity 2211.

[0078] The density of the conductive member 222 is less than the density of the ink in the ink storage chamber 211, which can cause at least a part of the conductive member 222 to float in the ink.

[0079] The conductive member 222 can be entirely made of a conductive material. In other embodiments, the conductive member 222 includes a body and a conductive coating coated on the outer side of the body. The material of the conductive coating can be a conductive material, and the material of the body can be a non-conductive material.

[0080] In this embodiment, the conductive member 222 is configured to be disengaged from the probe assembly when the ink level in the ink storage chamber 211 is lower than a preset height. When the ink level in the ink storage chamber 211 is lower than the preset height, the conductive member 222 is disengaged from the probe assembly, the two probes 223 are disconnected, and the printer can determine that the ink level in the liquid container 20 is too low (no ink or little remaining ink), the ink level in the ink storage chamber 211 is in an alarm state, and the printer can only operate normally after the liquid container 20 is replenished with ink; when the ink level in the ink storage chamber 211 is higher than the preset height, the conductive member 222 contacts the probe assembly, the two probes 223 are conducting, and the printer can determine that there is ink in the liquid container 20, enabling the printer to operate normally.

[0081] In other embodiments, the conductive member 222 is configured to contact the probe assembly when the ink level in the ink storage chamber 211 is lower than a preset height. When the ink level in the ink storage chamber 211 is lower than the preset height, the conductive member 222 contacts the probe assembly, and the two probes 223 are turned on. The printer can also determine that the ink volume in the liquid container 20 is too low (no ink or little remaining ink), and the ink level in the ink storage chamber 211 is in an alarm state. After the liquid container 20 is replenished with ink, the printer can work properly; when the ink level in the ink storage chamber 211 is higher than the preset height, the conductive member 222 is separated from the probe assembly, and the two probes 223 are turned off. The printer can also determine that there is ink in the liquid container 20, enabling the printer to work properly.

[0082] The detection principle of the ink detection mechanism 22 in this embodiment is as follows:

[0083] Figure 4 and Figure 5 the ink surface in is at the critical ink surface 213, and the height of this ink surface in the height direction of the liquid container 20 is the preset height.

[0084] See Figure 4 and Figure 5 As shown, when ink is continuously injected into the ink storage chamber 211 from the ink injection port 212, the conductive member 222 will continuously float upward in the height direction of the liquid container 20 until it contacts the two probes 223. At this time, the two probes 223 are turned on, and the printer can determine that there is ink in the liquid container 20. The liquid container 20 is in an ink state, and the ink surface in the ink storage chamber 211 is the critical ink surface 213.

[0085] Figure 6 and Figure 7 the ink surface in is at position D, and the height of this ink surface in the height direction of the liquid container 20 is higher than the preset height.

[0086] See Figure 6 and Figure 7 As shown, when ink is continuously injected into the ink storage chamber 211 from the ink injection port 212, in the first direction, the ink surface in the ink storage chamber 211 is higher than the critical ink surface 213, and the conductive member 222 always remains in contact with the two probes 223. The two probes 223 are turned on, and the liquid container 20 is in an ink state.

[0087] It should be noted that when ink is being used or injected into the ink storage chamber 211, in the first direction, as long as the ink surface in the ink storage chamber 211 is not lower than the critical ink surface 213, the conductive member 222 always remains in contact with the two probes 223. The two probes 223 are turned on, and the liquid container 20 is in an ink state.

[0088] Figure 8 andFigure 9 The ink surface in it is located at position E, and the height of the ink surface in the height direction of the liquid container 20 is lower than the preset height.

[0089] See Figure 8 and Figure 9 As shown, during the use of the printer, the ink in the ink storage cavity 211 will gradually decrease. When in the first direction, the ink surface in the ink storage cavity 211 is lower than the critical ink surface 213, the conductive member 222 is separated from the two probes 223, and the printer can determine that the ink level in the liquid container 20 is too low (no ink or little remaining ink), and the ink level in the ink storage cavity 211 is in an alarm state.

[0090] For the liquid container 20 provided by the embodiment of the present invention, when the conductive member 222 contacts the probe assembly, the probe assembly is turned on, indicating that there is ink. When the conductive member 222 is separated from the probe assembly, the probe assembly is not turned on, indicating that the ink level is too low. Thus, when no electrolyte is added to the ink, the printer can detect whether there is ink in the liquid container to ensure the normal use of the printer. Or, when the conductive member is separated from the probe assembly, the probe assembly is not turned on, indicating that there is ink. When the conductive member contacts the probe assembly, the probe assembly is turned on, indicating that the ink level is too low. Thus, when no electrolyte is added to the ink, the printer can detect whether there is ink in the liquid container to ensure the normal use of the printer.

[0091] In a possible implementation manner, in the first direction, the conductive member 222 is closer to the bottom of the container body 21 relative to the probe assembly. With such a setting, when the conductive member 222 contacts the two probes 223, in the first direction, the conductive member 222 can be located below the two probes 223, so that when the ink surface in the ink storage cavity 211 is lower than the critical ink surface 213, it is convenient for the conductive member 222 to be separated from the two probes 223.

[0092] The conductive member 222 can move along the first direction or along a direction having an angle with the first direction. In some examples, the frame body 221 is respectively connected to the front wall 21c and the right wall 21f of the container body 21. The frame body 221 and the front wall 21c and the right wall 21f of the container body 21 enclose a cavity 2211. In the third direction, the conductive member 222 has gaps with the front wall 21c of the container body 21 and the inner wall of the frame body 221 respectively. In the second direction, the conductive member 222 has gaps with the inner wall of the frame body 221 and the right wall 21f of the container body 21 respectively.

[0093] In a possible implementation manner, a plurality of ink ports are provided on the frame body 221, and the plurality of ink ports communicate the ink storage cavity 211 and the cavity 2211. With such a setting, the ink in the ink storage cavity 211 can enter the cavity 2211, so that the conductive member 222 moves as the ink surface in the ink storage cavity 211 changes.

[0094] The shape of the ink port is not specifically set. In some examples, the shape of the ink port can be square, circular, triangular, etc.

[0095] Further, referring to Figure 3 and Figure 4 As shown, a plurality of ink ports include a first ink port 221a and a second ink port 221b. The first ink port 221a and the second ink port 221b are located on both sides of the frame body 221 in the first direction. With such a setting, when in the first direction, the ink level in the ink storage cavity 211 is between the top and the bottom of the frame body 221, the ink level in the ink storage cavity 211 and the ink level in the frame body 221 are in the same plane, thereby ensuring the accuracy of the detection of the ink detection mechanism 22.

[0096] Among them, in the first direction, the first ink port 221a is located at the top of the frame body 221, and the second ink port 221b is located at the bottom of the frame body 221.

[0097] In some examples, the shape of the first ink port 221a is the same as the shape of the second ink port 221b. In the first direction, the projection of the first ink port 221a coincides with the projection of the second ink port 221b. With such a setting, it is convenient to process the first ink port 221a and the second ink port 221b.

[0098] In a possible implementation manner, the conductive member 222 is a spherical conductive member. The diameter of the spherical conductive member is greater than the distance between the two probes 223 in the second direction. With such a setting, when ink is continuously injected into the ink storage cavity 211 from the ink injection port 212, the conductive member 222 will continuously float upward in the height direction of the liquid container 20 and contact the two probes 223. The spherical conductive member will not pass through the two probes 223, improving the stability of the contact between the spherical conductive member and the two probes 223.

[0099] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
