[0023] Compared with the prior art, the beneficial effects of the present invention are that the present invention provides a board and a detection mechanism, and determines whether the operation of the ink cartridge meets the standard by using the board based on the inkjet volume measured by the detection mechanism, effectively improving the real-time monitoring effect and intelligent recognition ability of the nozzle inkjet volume, thereby achieving a high degree of matching of the operation parameters and precision requirements, effectively improving the printing quality of the printer using the ink cartridge of the present invention. At the same time, the board can also determine the reason why the operation of the ink cartridge does not meet the standard based on the historical inkjet volume, analyze the reason why the operation of the ink cartridge does not meet the standard, and further improve the operation parameters of the corresponding components in the ink cartridge based on the determined reason, further improving the intelligent recognition ability of the nozzle inkjet volume and further improving the printing quality of the printer using the ink cartridge of the present invention.

[0024] Further, the board card provided by the present invention is also used to generate corresponding processing instructions according to the determined cause, and timely adjust the operating state of the corresponding component of the cause to ensure the effective solution of the ink cartridge operation problem. While further achieving a high degree of matching of the operating parameters and accuracy requirements, the printing quality of the printer using the ink cartridge of the present invention is further improved.

[0025] Further, the present invention provides an adjustment mechanism at the connection between the ink inlet chamber and the nozzle at the bottom of the cartridge body, and controls the flow rate of the ink transported from the ink inlet chamber to the nozzle by an external component, further improving the printing quality of the printer using the ink cartridge of the present invention.

[0026] Further, the present invention sets a control module to send corresponding instructions to the corresponding components, so that each component operates with corresponding parameters to ensure that the nozzle outputs ink at a corresponding flow rate, so that the ink flow rate matches the required printing effect, and further improves the printing quality of the printer using the ink cartridge of the present invention.

[0027] Further, the present invention is provided with a temperature sensor at the connection between the ink inlet chamber and the adjustment mechanism to detect the temperature of the ink transported to the nozzle during printing, and keep the ink within a certain temperature range, so that the ink has the best fluidity. While further improving the printing quality of the printer using the ink cartridge of the present invention, the service life of the printer using the ink cartridge of the present invention is effectively extended.

[0028] Further, the present invention is provided with a liquid level float in the ink inlet chamber to real-time monitor the height of the ink in the ink inlet chamber. The liquid level float will rise or fall correspondingly as the height of the ink in the ink inlet chamber rises or falls. When the height of the ink in the ink inlet chamber is too high or too low, the liquid level float will issue an alarm in time to remind the user to process it in time to ensure that the height of the ink in the ink inlet chamber always remains at an appropriate level, thereby effectively avoiding the situation that printing cannot be performed due to too little or too much ink in the ink inlet chamber of the ink cartridge. While further improving the printing quality of the printer using the ink cartridge of the present invention, the use efficiency of the printer using the ink cartridge of the present invention is effectively guaranteed.

[0029] Further, the present invention is provided with an ink cartridge cover on the ink cartridge to prevent the external environment from contaminating the ink in the cartridge body, maintain a good storage environment for the ink, and facilitate the ink inlet chamber to transport higher-quality ink to the nozzle, further improving the printing quality of the printer using the ink cartridge of the present invention.

[0030] Furthermore, in the present invention, an ink inlet gas pipe joint for connecting the ink inlet chamber with the corresponding pipeline and an ink return gas pipe joint for connecting the ink return chamber with the corresponding pipeline are provided on the ink cartridge cover. The ink inlet gas pipe joint is used to convey gas to the ink inlet chamber to increase the air pressure in the ink inlet chamber, thereby ensuring that the ink in the ink inlet chamber can be stably conveyed to the nozzle. At the same time, the ink return gas pipe joint is used to extract the gas in the ink return chamber to keep the ink return chamber in a low-pressure state, ensuring that the waste ink from the nozzle is recovered into the ink return chamber, avoiding the influence of the accumulation of waste ink on the inkjet volume ejected by the nozzle, and further improving the printing quality of the printer using the ink cartridge of the present invention.

[0031] Furthermore, the present invention combines the ink inlet chamber and the ink return chamber into one, improving the current situation that traditional ink cartridges are usually composed of two components, optimizing the number of components of the ink cartridge, reducing the space occupied by the ink cartridge in the printer, and thus effectively reducing the production cost of the ink cartridge of the present invention.

[0032] Furthermore, the board provided in the present invention is used to receive the inkjet volume of the nozzle measured by the detection mechanism in a single detection cycle, to monitor the inkjet volume of the nozzle in real time, and to determine whether the operation of the ink cartridge meets the standard based on the intelligent recognition and comparison result of the inkjet volume and the preset inkjet volume pre-stored in the board. While further improving the intelligent recognition ability of the inkjet volume of the nozzle, the printing quality of the printer using the ink cartridge of the present invention is further improved.

[0033] Furthermore, the board provided in the present invention is also used to intelligently identify the reason why the operation of the ink cartridge does not meet the standard in a single detection cycle based on the variance of each historical inkjet volume in a preset number of historical detection cycles. The variance of each historical inkjet volume in a preset number of historical detection cycles reflects its degree of dispersion. The reasons for the non-compliance of the ink cartridge operation are different, and their variances are different. Therefore, based on the variance, the reason for the non-compliance of the operation in a single detection cycle can be determined. While further improving the intelligent recognition ability of the inkjet volume of the nozzle, the printing quality of the printer using the ink cartridge of the present invention is further improved.

[0034] Furthermore, the adjustment mechanism provided in the present invention is a two-way solenoid valve. The two-way solenoid valve controls the flow rate of the ink conveyed from the ink inlet chamber to the nozzle through electromagnetic force. The control of the electromagnetic force used has excellent performance. It can achieve efficient adjustment of the ink flow rate while responding quickly, and further improves the printing quality of the printer using the ink cartridge of the present invention.

[0035] Further, the board card provided by the present invention is also used to analyze the accuracy requirement based on the obtained inkjet volume difference to determine the opening value of the adjustment mechanism, adjust the corresponding operating parameters. The inkjet volume difference is the gap between the measured inkjet volume and the preset inkjet volume. Adjusting the opening value of the adjustment mechanism can change the inkjet volume of the print head. While further achieving a high degree of matching between the operating parameters and the accuracy requirement, the printing quality of the printer using the ink cartridge of the present invention is further improved.

[0036] Further, the board card provided by the present invention is also used to correct the opening of the adjusted adjustment mechanism to the corresponding value based on the height of the liquid level float. The height of the ink affects the inkjet volume of the print head. The height of the liquid level float will rise or fall correspondingly as the ink in the ink supply chamber rises or falls. Therefore, based on the height of the liquid level float, the opening value of the adjusted adjustment mechanism can be further corrected. While further achieving a high degree of matching between the operating parameters and the accuracy requirement, the printing quality of the printer using the ink cartridge of the present invention is further improved.

[0037] Further, the board card provided by the present invention is also used to determine the ink return air pressure at the ink return gas pipe joint based on the obtained variance difference. The variance difference is the difference between the measured variance and the first preset variance. The variance difference can reflect the gap between the variance under a single detected state and the first preset variance, that is, the gap between the degree of dispersion and the preset degree of dispersion. According to the gap, the accumulation degree of waste ink of the print head can be determined. The recovery of the waste ink of the print head can be realized by adjusting the ink return air pressure, thereby effectively avoiding the influence of the accumulation of waste ink of the print head on the inkjet process. While further achieving a high degree of matching between the operating parameters and the accuracy requirement, the printing quality of the printer using the ink cartridge of the present invention is further improved.

[0038] Further, the board card provided by the present invention is also used to determine the ink supply air pressure at the ink supply gas pipe joint based on the height of the liquid level float. The height of the liquid level float will rise or fall correspondingly as the ink in the ink supply chamber rises or falls. The ink supply gas pipe joint can adjust the air pressure in the ink supply chamber to realize the adjustment of the ink height and ensure that the inkjet volume reaches the preset level. While further achieving a high degree of matching between the operating parameters and the accuracy requirement, the printing quality of the printer using the ink cartridge of the present invention is further improved.

[0039] Furthermore, the present invention provides a smooth area inside the ink inlet chamber, where the liquid level float ball is located. The smooth area enables the liquid level float ball to move more smoothly, improving the detection accuracy of the liquid level. There are a first-level liquid level mark and a second-level liquid level mark in the smooth area, which are used in conjunction with the liquid level float ball to determine the ink content in the ink inlet chamber. The two liquid levels can improve the monitoring sensitivity for the ink height, ensuring that the ink in the ink inlet chamber is maintained within an appropriate range. While further improving the printing quality of the printer using the cartridge of the present invention, the usage efficiency of the printer using the cartridge of the present invention is further guaranteed.

[0040] Furthermore, the present invention provides a through hole at the top of the cartridge cover located in the smooth area, and a liquid level pressing cover is provided at the through hole. A restraint rod is provided at the bottom of the liquid level pressing cover, and the liquid level float ball is sleeved on the restraint rod and can move along the direction of the restraint rod. This is beneficial for the liquid level float ball to move along the corresponding trajectory when rising or sinking in the ink inlet chamber, avoiding the situation where the liquid level height cannot be clearly identified due to the movement of the liquid level float ball. While further improving the printing quality of the printer using the cartridge of the present invention, the usage efficiency of the printer using the cartridge of the present invention is further guaranteed.

[0050] Please refer to Figure 1 As shown, it is a right-side sectional view of the integrated ink volume and flow rate self-regulating ink cartridge of the present invention. The integrated ink volume and flow rate self-regulating ink cartridge of the present invention includes a cartridge body 12, a nozzle 13, a detection mechanism 19, an adjustment mechanism 4, and a control module (not shown in the figure); wherein, the cartridge body 12 is used to store ink, the nozzle 13 is arranged at the output end of the cartridge body 12 to receive the ink output by the cartridge body 12 and spray it out; the detection mechanism 19 is arranged at the nozzle of the nozzle 13 to detect the inkjet volume output by the nozzle 13; the adjustment mechanism 4 is arranged at the connection between the bottom of the cartridge body 12 and the nozzle 13 to control the flow rate of the ink conveyed from the cartridge body 12 to the nozzle 13; the control module is respectively connected to the detection mechanism 19 and the adjustment mechanism 4 to send instructions to the corresponding components to adjust the operating parameters of each component to the corresponding values.

[0051] When the integrated ink volume and flow rate self-regulating ink cartridge of the present invention operates, the control module issues instructions to the corresponding components, and each component adjusts the corresponding operating parameters to the corresponding values according to the received instructions to complete the control of the ink flow rate output by the cartridge body 12. At this time, the cartridge body 12 conveys ink to the nozzle 13 at the corresponding flow rate, and the nozzle 13 sprays out the ink after receiving the ink to complete the printing of the document.

[0052] In the present invention, the detection mechanism 19 is provided at the nozzle of the nozzle 13 of the print head to detect the ink jet volume output by the print head 13. By monitoring the ink jet volume at the print head 13 in real time, it can effectively ensure that the print head 13 jets ink according to the corresponding standard, and effectively improves the printing quality of the printer using the ink cartridge of the present invention.

[0053] The present invention sets a control module to send corresponding instructions to corresponding components, so that each component operates with corresponding parameters, so as to ensure that the print head 13 outputs ink at a corresponding flow rate, so as to ensure that the adjustment mechanism 4 can accurately control the flow rate of the ink delivered from the cartridge body 12 to the print head 13, making the ink flow more match the required printing effect, and further improving the printing quality of the printer using the ink cartridge of the present invention.

[0054] Please continue to refer to Figure 1 As shown, a cartridge cover 2 is provided on the cartridge body 12 of the present invention to enclose the internal space of the cartridge body 12. A sealing ring 18 is provided on the side of the cartridge cover 2 close to the cartridge body 12 to better achieve the sealing of the cartridge body 12.

[0055] In the present invention, the cartridge body 12 is sealed by providing the cartridge cover 2 on the cartridge body 12, which can prevent the external environment from polluting the ink in the cartridge body 12, thereby maintaining a good storage environment for the ink. Further, the sealing ring 18 is provided on the side of the cartridge cover 2 close to the cartridge body 12. The setting of the sealing ring 18 makes the cartridge cover 2 fit better with the cartridge body 12, achieving a better sealing effect on the cartridge, further preventing the external environment from polluting the ink in the cartridge body 12, and further improving the printing quality of the printer using the ink cartridge of the present invention.

[0056] Specifically, the cartridge body 12 is made of aluminum material metal, and the formed oxide film can prevent the cartridge body 12 from reacting with the ink.

[0057] In the present invention, the cartridge body 12 is made of aluminum material metal. The aluminum material metal will be oxidized on the surface of the cartridge body 12 to form an oxide film. The formed oxide film can prevent the cartridge body 12 from undergoing a chemical reaction with the ink, and has a protective effect on both the cartridge body 12 itself and the ink in the cartridge body 12, thereby effectively ensuring the quality of the ink delivered from the cartridge body 12 to the print head 13, and further improving the printing quality of the printer using the ink cartridge of the present invention.

[0058] Specifically, the cartridge body 12 is made by a black oxidation process, and the further formed oxide layer on the surface of the cartridge body 12 can further prevent the cartridge body 12 from undergoing a chemical reaction with the ink.

[0059] In the present invention, the cartridge body 12 is prepared by a black oxidation process, so that an oxide layer is further formed on the surface of the oxide layer of the cartridge body 12. The surface of the further formed oxide layer can further prevent the cartridge body 12 from chemically reacting with the ink, playing a protective role for the ink in the cartridge body 12, and also avoiding the corrosion of the cartridge body 12 caused by the occurrence of chemical reactions, making the cartridge body 12 have good durability and stability, thereby further ensuring the quality of the ink delivered from the cartridge body 12 to the print head 13, and further improving the printing quality of the printer using the cartridge of the present invention.

[0060] Please refer to Figure 2 As shown, it is a front sectional view of the integrated ink volume and flow self-regulating cartridge according to an embodiment of the present invention. The cartridge body 12 of the integrated ink volume and flow self-regulating cartridge of the present invention includes an ink inlet chamber 7, an ink inlet 8, an ink inlet gas pipe joint 6, a waste ink chamber 10, a waste ink outlet 11, and a waste ink return gas pipe joint 9; wherein, the ink inlet chamber 7 is opened in the cartridge body 12 for loading ink, the ink inlet 8 is opened on the side wall of the ink inlet chamber 7 for supplementing external ink to the ink inlet chamber 7, and the ink inlet gas pipe joint 6 is opened on the top of the ink inlet chamber 7 for delivering gas into the ink inlet chamber 7; the waste ink chamber 10 is opened in the cartridge body 12 for storing waste ink, the waste ink outlet 11 is opened at the bottom of the waste ink chamber 10 for delivering the waste ink at the print head 13 to the waste ink chamber 10, and the waste ink return gas pipe joint 9 is opened on the top of the waste ink chamber 10 for extracting the gas in the waste ink chamber 10.

[0061] When the integrated ink volume and flow self-regulating cartridge of the present invention operates, the ink inlet gas pipe joint 6 delivers gas into the ink inlet chamber 7 to increase the pressure, so that the ink inlet chamber 7 delivers ink to the print head 13 and the ink is ejected from the print head 13; the waste ink return gas pipe joint 9 releases the gas in the waste ink chamber 10 to reduce the pressure, so that the waste ink generated at the print head 13 can flow into the waste ink chamber 10 through the waste ink outlet 11; when the ink inlet chamber 7 needs ink supplementation, the ink inlet 8 can supplement external ink to the ink inlet chamber 7.

[0062] By combining the ink inlet chamber 7 and the waste ink chamber 10 into one, the present invention improves the current situation that traditional cartridges are usually composed of two components, optimizes the number of components of the cartridge, reduces the space occupied by the cartridge in the printer, and thus effectively reduces the production cost of the cartridge of the present invention.

[0063] In the present invention, an ink inlet 8 is provided on the side wall of the ink supply chamber 7. When the ink in the ink supply chamber 7 needs to be replenished, external ink can be input into the ink supply chamber 7 through the ink inlet 8, thereby effectively ensuring the delivery of the ink in the ink supply chamber 7 to the print head 13; a waste ink outlet 11 is provided at the bottom of the waste ink return chamber 10, which is conducive to the timely and effective delivery of the waste ink generated at the print head 13 to the waste ink return chamber 10, ensuring that the waste ink of the print head 13 is recycled to the waste ink return chamber 10, avoiding the influence of the accumulation of waste ink on the ink jet volume ejected by the print head, and further improving the printing quality of the printer using the ink cartridge of the present invention.

[0064] In the present invention, an ink supply gas pipe joint 6 for connecting the ink supply chamber 7 with a corresponding pipeline and a waste ink return gas pipe joint 9 for connecting the waste ink return chamber 10 with a corresponding pipeline are provided on the ink cartridge cover 2. The ink supply gas pipe joint 6 is used to supply gas to the ink supply chamber 7 to increase the air pressure in the ink supply chamber 7, so as to ensure that the ink in the ink supply chamber 7 can be stably delivered to the print head 13. At the same time, the waste ink return gas pipe joint 9 is used to extract the gas in the waste ink return chamber 10 to make the inside of the waste ink return chamber 10 in a low-pressure state, ensuring that the waste ink of the print head 13 is recycled to the waste ink return chamber 10, avoiding the influence of the accumulation of waste ink on the ink jet volume ejected by the print head, and further improving the printing quality of the printer using the ink cartridge of the present invention.

[0065] Please refer to Figure 1 and Figure 2 As shown, the ink supply chamber 7 of the integrated ink volume and flow self-regulating ink cartridge of the present invention includes a temperature sensor 5, a smooth area 14, a liquid level gland 1, a restraining rod 15 and a liquid level float 3; wherein, the temperature sensor 5 is arranged at the connection between the ink supply chamber 7 and the regulating mechanism 4, and is used to detect the temperature of the ink delivered from the ink supply chamber 7 to the print head 13; the liquid level gland 1 is arranged at a through hole opened at the top of the smooth area 14 on the ink cartridge cover 2, and is used to prevent external dust from entering the cartridge body 12; the restraining rod 15 is located at the bottom of the liquid level gland 1 and the liquid level float 3 is sleeved on the restraining rod 15, and is used to restrain the liquid level float 3.

[0066] When the integrated ink volume and flow self-regulating ink cartridge of the present invention operates, the liquid level float 3 in the smooth area 14 will monitor the height of the ink in the ink supply chamber 7. When the height of the ink in the ink supply chamber 7 rises or falls, the liquid level float 3 will rise or sink correspondingly along the direction of the restraining rod 15. When the height of the ink is too high or too low, the liquid level float 3 moves to the corresponding position along the restraining rod 15, converts the obtained height position into a corresponding electrical signal, and transmits the electrical signal to a display module (not shown in the figure) to send out an alarm.

[0067] The present invention arranges the temperature sensor 5 at the connection between the ink inlet bin 7 and the regulating mechanism 4, so as to detect the temperature of the ink delivered to the nozzle 13 during printing, thereby keeping the ink within a certain temperature range so that the ink has optimal fluidity, further improving the printing quality of the printer using the ink cartridge of the present invention, and effectively extending the service life of the printer using the ink cartridge of the present invention.

[0068] The present invention sets the smooth area 14 in the ink inlet bin 7, and the liquid level float 3 is located in the smooth area 14. The smooth area 14 allows the liquid level float 3 to move more smoothly, thereby improving the detection accuracy of the liquid level. While further improving the printing quality of the printer using the ink cartridge of the present invention, it effectively ensures the use efficiency of the printer using the ink cartridge of the present invention.

[0069] The liquid level float 3 described in the present invention can monitor the height of the ink in the ink inlet bin 7 in real time. The liquid level float 3 will rise or sink accordingly as the height of the ink in the ink inlet bin 7 rises or falls. When the height of the ink in the ink inlet bin 7 is too high or too low, the liquid level float 3 will promptly issue an alarm to remind the user to deal with it in time to ensure that the height of the ink in the ink inlet bin 7 is always maintained at an appropriate level, effectively avoiding the situation where there is too little or too much ink in the ink inlet bin 7 resulting in the inability to print. While further improving the printing quality of the printer using the ink cartridge described in the present invention, the use efficiency of the printer using the ink cartridge described in the present invention is further guaranteed.

[0070] The present invention opens a through hole at the top of the ink cartridge cover 2 located in the smooth area 14, arranges the liquid level pressure cover 1 at the through hole, and arranges the constraint rod 15 at the bottom of the liquid level pressure cover 1, so that the liquid level float 3 can be sleeved on the constraint rod 15 and can move along the direction of the constraint rod 15, which is beneficial for the liquid level float 3 to move along the corresponding trajectory when rising or sinking in the ink inlet bin 7, avoiding the situation that the liquid level height cannot be clearly identified due to the movement of the float, while further improving the printing quality of the printer using the ink cartridge of the present invention, and further ensuring the use efficiency of the printer using the ink cartridge of the present invention.

[0071] Please continue reading Figure 1 and Figure 2 As shown, the smooth area 14 of the integrated ink flow self-regulating ink cartridge of the present invention includes a primary liquid level mark 16 and a secondary liquid level mark 17; wherein, the primary liquid level mark 16 is located on the side wall of the smooth area 14 to indicate that the ink height in the ink inlet tank 7 is too low, and the secondary liquid level mark 17 is arranged on the side wall of the smooth area 14 and is located above the primary liquid level mark 16 to indicate that the ink height in the ink inlet tank 7 is too high.

[0072] When the integrated ink volume and flow self-regulating ink cartridge of the present invention is in operation, when the liquid level float ball 3 moves along the direction of the constraint rod 15 to a position lower than the first liquid level mark 16, an alarm signal indicating that the ink height is too low will be emitted; when the liquid level float ball 3 moves along the direction of the constraint rod 15 to a position higher than the second liquid level mark 17, an alarm signal indicating that the ink height is too high will be emitted.

[0073] In the present invention, the first liquid level mark 16 and the second liquid level mark 17 are provided in the smooth area 14 in the ink inlet chamber 7 to cooperate with the liquid level float ball 3 to determine the height of the ink in the ink inlet chamber 7. The two liquid levels can improve the monitoring sensitivity for the ink height, ensure that the height of the ink in the ink inlet chamber 7 is maintained within an appropriate range, and while further improving the printing quality of the printer using the ink cartridge of the present invention, it further ensures the usage efficiency of the printer using the ink cartridge of the present invention.

[0074] Please refer to Figure 3 As shown, it is a schematic diagram of the connection of the integrated ink volume and flow self-regulating ink cartridge module according to an embodiment of the present invention. The ink cartridge of the present invention further includes a board (not shown in the figure), which is connected to the detection mechanism 19 and the control module. The board can obtain the inkjet volume measured by the detection mechanism 19 and output a processing instruction to the control module.

[0075] When the integrated ink volume and flow self-regulating ink cartridge of the present invention is in operation, the board can perform intelligent identification and comparison based on the inkjet volume obtained by the detection mechanism 19 and the preset inkjet volume to determine whether the operation of the ink cartridge meets the standard. At the same time, based on the historical inkjet volume, the reason for the non-compliance of the ink cartridge operation is determined; the board is also used to generate corresponding processing instructions according to the determined reason and adjust the operating parameters of the corresponding components to the corresponding values through the control module.

[0076] The board card of the present invention can determine whether the operation of the ink cartridge meets the standard based on the inkjet volume measured by the detection mechanism, effectively improving the real-time monitoring effect and intelligent recognition ability of the nozzle inkjet volume, thereby achieving a high degree of matching between the operating parameters and accuracy requirements, and further improving the printing quality of the printer using the ink cartridge of the present invention. At the same time, the board card can also determine the reason why the operation of the ink cartridge does not meet the standard based on the historical inkjet volume, analyze the reason why the operation of the ink cartridge does not meet the standard, and further improve the operating parameters of the corresponding components in the ink cartridge based on the determined reason. While further improving the intelligent recognition ability of the nozzle inkjet volume, the printing quality of the printer using the ink cartridge of the present invention is further improved. Further, the board card provided in the present invention is also used to generate corresponding processing instructions according to the determined reason, and timely adjust the operating state of the corresponding components causing the reason, ensuring the effective solution of the operation problems of the ink cartridge. While further achieving a high degree of matching between the operating parameters and accuracy requirements, the printing quality of the printer using the ink cartridge of the present invention is further improved.

[0077] Please refer to Figure 4 As shown, it is the working flowchart of the board card of the integrated ink volume and flow self-regulating ink cartridge according to the embodiment of the present invention. When the integrated ink volume and flow self-regulating ink cartridge of the present invention operates, the board card is used to receive the inkjet volume of the nozzle 13 measured by the detection mechanism 19 in a single detection cycle, and determine whether the operation of the ink cartridge meets the standard based on the comparison result of the inkjet volume and the preset inkjet volume pre-stored in the board card; where the preset inkjet volume Q0 is set to 3.2 ml / s:

[0078] If the inkjet volume is greater than or equal to the preset inkjet volume Q0, the board card determines that the operation of the ink cartridge meets the standard;

[0079] If the inkjet volume is less than the preset inkjet volume Q0, the board card determines that the operation of the ink cartridge does not meet the standard, and the board card determines the reason why the operation of the ink cartridge does not meet the standard in the current cycle based on the historical inkjet volume in the historical detection cycles it obtains.

[0080] The board card of the present invention is used to receive the inkjet volume of the nozzle 13 measured by the detection mechanism to monitor the inkjet volume of the nozzle 13 in real time, and determine whether the operation of the ink cartridge meets the standard based on the intelligent recognition comparison result of the inkjet volume and the preset inkjet volume pre-stored in the board card. While further improving the intelligent recognition ability of the nozzle inkjet volume, the printing quality of the printer using the ink cartridge of the present invention is further improved.

[0081] Please continue to refer to Figure 4As shown, when the integrated ink volume and flow rate self-regulating ink cartridge of the present invention is in operation, the board is further configured to determine the reason why the operation of the ink cartridge does not meet the standard in a single detection period based on the variance of the historical inkjet volumes in a preset number of historical detection periods obtained, and generate a corresponding processing method based on the determined reason why the operation of the ink cartridge does not meet the standard in a single detection period, where:

[0082] If the variance is less than or equal to the first preset variance C1 set in the board, the board determines that the reason for the non-compliance of the ink cartridge operation with the standard is that the opening degree of the regulating mechanism 4 does not meet the standard, and the board re-determines the opening degree of the regulating mechanism 4 based on the inkjet volume. In this embodiment, the first preset variance C1 = 0.12;

[0083] If the variance is greater than the first preset variance C1 and less than or equal to the second preset variance C2 set in the board, the board determines that the reason for the non-compliance of the ink cartridge operation with the standard is that there is waste ink in the nozzle 13, and the board determines the backflow air pressure at the backflow air pipe joint 9 based on the obtained variance value. In this embodiment, the second preset variance C2 = 0.23;

[0084] If the variance is greater than the second preset variance C2, the board determines that the reason for the non-compliance of the ink cartridge operation with the standard is that the ink loading amount in the ink inlet chamber 7 is lower than the preset standard, and the board determines the ink inlet air pressure at the ink inlet pipe joint 6 based on the height of the liquid level float 3.

[0085] The board of the present invention is further configured to intelligently identify the reason for the non-compliance of the operation of the ink cartridge in a single detection period based on the variance of the historical inkjet volumes in a preset number of historical detection periods obtained. The variance of the historical inkjet volumes in a preset number of historical detection periods reflects its degree of dispersion. Different reasons for the non-compliance of the ink cartridge operation result in different variances. Therefore, based on the variance, the reason for the non-compliance of the operation in a single detection period can be determined, which further improves the intelligent identification ability of the nozzle inkjet volume and further improves the printing quality of the printer using the ink cartridge of the present invention.

[0086] Please continue to refer to Figure 4 As shown, when the integrated ink volume and flow rate self-regulating ink cartridge of the present invention is in operation, the regulating mechanism 4 is a solenoid valve, and the board is further configured to increase the opening degree value of the regulating mechanism 4 based on the obtained inkjet volume difference, and the increase amplitude of the opening degree value is proportional to the inkjet volume difference, where the inkjet volume difference is the difference between the preset inkjet volume and the inkjet volume measured by the detection mechanism 19:

[0087] If the difference in inkjet volume is greater than the second preset inkjet volume difference △Q2 set in the board, the board determines to adjust the opening value of the adjusting mechanism 4 to 1.65 times the initial opening value. In this embodiment, the second preset inkjet volume difference △Q2 = 1.5 ml / s;

[0088] If the difference in inkjet volume is less than or equal to the second preset inkjet volume difference △Q2 and greater than the first preset inkjet volume difference △Q1 set in the board, the board determines to adjust the opening value of the adjusting mechanism 4 to 1.33 times the initial opening value. In this embodiment, the first preset inkjet volume difference △Q1 = 0.9 ml / s;

[0089] If the difference in inkjet volume is less than or equal to the first preset inkjet volume difference △Q1, the board determines to adjust the opening value of the adjusting mechanism 4 to 1.16 times the initial opening value.

[0090] The adjusting mechanism 4 of the present invention is a two-way solenoid valve. The two-way solenoid valve controls the flow rate of the ink transported from the ink supply chamber 7 to the nozzle through electromagnetic force. The control of the electromagnetic force used has excellent performance. It can achieve efficient adjustment of the ink flow rate while responding quickly, further improving the printing quality of the printer using the ink cartridge of the present invention. It can be understood that the adjusting mechanism 4 of the present invention can be a two-way solenoid valve or other types of structures controlled by electromagnetic force, as long as it can ensure that the adjusting mechanism 4 can accurately control the ink flow rate in the output pipeline of the cartridge body 12.

[0091] The board of the present invention is also used to analyze the accuracy requirements based on the obtained difference in inkjet volume to determine the opening value of the adjusting mechanism 4, and adjust the corresponding operating parameters. The difference in inkjet volume is the gap between the measured inkjet volume and the preset inkjet volume. Adjusting the opening value of the adjusting mechanism 4 can change the inkjet volume of the nozzle, further improving the printing quality of the printer using the ink cartridge of the present invention while further achieving a high degree of matching between the operating parameters and the accuracy requirements.

[0092] Please continue to refer to Figure 4 As shown, when the integrated ink volume and flow rate self-adjusting ink cartridge of the present invention operates, the board is also used to correct the opening value of the adjusted adjusting mechanism 4 based on the height of the liquid level float 3, and the correction amplitude of the opening value is inversely proportional to the height of the liquid level float 3:

[0093] If the height of the liquid level float 3 is greater than the second preset height H2 set in the board, the board determines to correct the opening value of the adjusting mechanism 4 to 1.03 times the adjusted opening value. In this embodiment, the second preset height H2 = 160 mm;

[0094] If the height of the liquid level float ball 3 is less than or equal to the second preset height H2 and greater than the first preset height H1 set in the board, the board determines to correct the opening value of the adjusting mechanism 4 to 1.12 times of the adjusted opening value. Wherein, in this embodiment, the first preset height H1 = 90 mm;

[0095] If the height of the liquid level float ball 3 is less than or equal to the first preset height H1, the board determines to correct the opening value of the adjusting mechanism 4 to 1.24 times of the adjusted opening value.

[0096] The board of the present invention is further configured to correct the opening of the adjusted adjusting mechanism 4 to a corresponding value based on the height of the liquid level float ball 3. The height of the ink affects the inkjet volume of the inkjet head 13. The height of the liquid level float ball 3 will rise or fall correspondingly as the ink in the ink supply chamber 7 rises or falls. Therefore, based on the height of the liquid level float ball 3, the opening value of the adjusted adjusting mechanism 4 can be further corrected, while further achieving a high degree of matching of the operating parameters and accuracy requirements, and further improving the printing quality of the printer using the ink cartridge of the present invention.

[0097] Please continue to refer to Figure 4 As shown, when the integrated ink volume flow self-adjusting ink cartridge of the present invention is operating, the board is further configured to increase the ink return pressure at the ink return pipe joint 9 based on the obtained variance difference, and the increase amplitude of the ink return pressure is inversely proportional to the variance difference, where the variance difference is the difference between the measured variance and the first preset variance:

[0098] When the integrated ink volume flow self-adjusting ink cartridge of the present invention is operating, if the variance difference is greater than the second preset variance difference △C2 set in the board, the board determines to adjust the ink return pressure at the ink return pipe joint 9 to 1.22 times of the initial ink return pressure. Wherein, in this embodiment, the second preset variance difference △C2 = 0.08;

[0099] If the variance difference is less than or equal to the second preset variance difference △C2 and greater than the first preset inkjet volume difference △C1 set in the board, the board determines to adjust the ink return pressure at the ink return pipe joint 9 to 1.41 times of the initial ink return pressure. Wherein, in this embodiment, the first preset inkjet volume difference △C1 = 0.05;

[0100] If the variance difference is less than or equal to the first preset variance difference △C1, the board determines to adjust the ink return pressure at the ink return pipe joint 9 to 1.68 times of the initial ink return pressure.

[0101] The board card according to the present invention is further configured to determine the ink return air pressure at the ink return air pipe joint 9 based on the obtained variance difference. The variance difference is the difference between the measured variance and the first preset variance. The variance difference can reflect the gap between the variance in a single detected state and the first preset variance, that is, the gap between the degree of dispersion and the preset degree of dispersion. According to the gap, the accumulation degree of waste ink in the nozzle 13 can be determined. The recovery of waste ink in the nozzle 13 can be achieved by adjusting the ink return air pressure, thereby effectively avoiding the influence of the accumulation of waste ink in the nozzle 13 on the inkjet process. While further achieving a high degree of matching between the operating parameters and the accuracy requirements, the printing quality of the printer using the ink cartridge according to the present invention is further improved.

[0102] Please continue to refer to Figure 4 As shown, when the integrated ink volume and flow self-adjusting ink cartridge according to the present invention is operating, the board card is further configured to increase the ink inlet air pressure at the ink inlet air pipe joint 6 based on the height of the liquid level float 3, and the increase amplitude of the ink inlet air pressure is inversely proportional to the height of the liquid level float 3:

[0103] When the integrated ink volume and flow self-adjusting ink cartridge according to the present invention is operating, if the height of the liquid level float 3 is greater than the second preset height H2 set in the board card, the board card determines to adjust the ink inlet air pressure at the ink inlet air pipe joint 6 to 1.22 times the initial ink inlet air pressure;

[0104] If the height of the liquid level float 3 is less than or equal to the second preset height H2 and greater than the first preset height H1 set in the board card, the board card determines to adjust the ink inlet air pressure at the ink inlet air pipe joint 6 to 1.41 times the initial ink inlet air pressure;

[0105] If the height of the liquid level float 3 is less than or equal to the first preset height H1, the board card determines to adjust the ink inlet air pressure at the ink inlet air pipe joint 6 to 1.68 times the initial ink inlet air pressure.

[0106] The board card according to the present invention is further configured to determine the ink inlet air pressure at the ink inlet air pipe joint 6 based on the height of the liquid level float 3. The height of the liquid level float 3 will rise or fall correspondingly as the ink in the ink inlet chamber rises or falls. The ink inlet air pipe joint 6 can adjust the air pressure in the ink inlet chamber to achieve the adjustment of the ink height and ensure that the inkjet volume reaches the preset level. While further achieving a high degree of matching between the operating parameters and the accuracy requirements, the printing quality of the printer using the ink cartridge according to the present invention is further improved.
