Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically stated. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically stated.

[0044] like Figure 1 As shown, the utility model discloses a structural schematic diagram of an ink cartridge, including: an ink cartridge box 1, an ink cartridge cover 2, the ink cartridge box 1 includes a plurality of heating holes 4, each heating hole 4 is respectively installed with a heating rod 3, each heating rod 3 is respectively connected to a control module of the ink cartridge heating system, the ink cartridge cover 2 and the ink cartridge box 1 are detachably connected, and an ink cartridge cavity 5 is formed between the ink cartridge cover 2 and the ink cartridge box 1, and the heating holes 4 are arranged along the ink cartridge cavity 5.

[0045] The control module of the ink cartridge heating system can realize the control function through any module with control function, such as a microprocessor, a single chip microcomputer or an FPGA.

[0046] In one embodiment, the number of heating holes 4 is one or more, the number of heating rods 3 is one or more, and one or more heating rods 3 can be installed in each heating hole 4. In this embodiment, there is no limitation on the number of heating holes 4, the number of heating rods 3, and the number of heating rods 3 installed in the heating holes 4. When the ink in the ink cartridge cavity 5 is heated by multiple heating rods 3, it is beneficial to improve the heating uniformity.

[0047] In one embodiment, the heating hole 4 in this embodiment can be set along the ink cartridge cavity 5 at any position or a combination of multiple positions on the left side, right side, front side, rear side and bottom of the ink cartridge box 1. One or more heating holes 4 can be set on each side. In this embodiment, the specific position of the heating hole on the ink cartridge box 1 is not limited.

[0048] It should be noted that the heating hole 4 in this embodiment is arranged in the box body of the ink cartridge box 1, and the heating hole 4 is not connected to the ink cartridge cavity 5, that is, the heating rod 3 will not directly contact the ink in the ink cartridge cavity 5. The heating rod 3 needs to heat the ink in the ink cartridge cavity 5 by heating the ink cartridge box 1, which is beneficial to improve the uniformity of ink heating. Compared with the heating rod 3 directly heating the ink in the ink cartridge cavity 5, the possibility of overheating is reduced.

[0049] In one embodiment, the ink cartridge cover 2 and the ink cartridge box 1 can be detachably connected by using fixing screws, or the ink cartridge cover 2 and the ink cartridge box 1 can be detachably connected by using fixing buckles. In this embodiment, there is no limitation on the detachable connection method between the ink cartridge cover 2 and the ink cartridge box 1.

[0050] In one embodiment, the control module in this embodiment controls the input current of the heating rod 3. When the ink in the ink cartridge chamber 5 needs to be heated, the control module of the inkjet device turns on or increases the input current of the heating rod 3, so that the heating rod 3 starts heating or increases the heating rate, and then the heat is transferred to the ink in the ink cartridge chamber 5 through the ink cartridge box 1 through the heating rod 3, thereby increasing the ink temperature; when the ink cartridge heating is completed or the temperature is too high, the control module of the inkjet device reduces the input current of the heating rod 3 or turns off the input current of the heating rod, so that the heating rod 3 reduces the heating rate or stops heating.

[0051] To sum up, in this embodiment, a heating rod 3 is installed in the heating hole 4 on the ink cartridge box 1, and the ink in the ink cartridge is heated by the heating rod 3. Compared with the heating sheet being attached to the ink cartridge box 1 by adhesive, the stability of the ink cartridge heating structure can be improved.

[0052] In addition, since only one side of the heating sheet is adhered to the ink cartridge box 1 and the other side of the heating sheet is exposed to the air, only one side of the heating sheet can heat the ink cartridge box 1, and the side of the heating sheet exposed to the air will cause a large amount of heat loss, resulting in a low heating efficiency of the heating sheet. In this embodiment, since the heating rod is inserted into the heating hole of the ink cartridge box 1, all the heat of the heating rod can be used to heat the ink cartridge box 1. Compared with the heating sheet heating the ink cartridge box 1, the purpose of improving the heating efficiency can be achieved.

[0053] In addition, the ink cartridge in this embodiment further includes an ink inlet interface 24 , which is connected to the ink cartridge cavity 5 , and is used to replenish ink into the ink cartridge cavity 5 .

[0054] refer to Figure 1 As shown, the ink cartridge heating system of the present invention includes a temperature sensor 6 , and the ink cartridge box 1 is provided with a sensor mounting position 7 .

[0055] The temperature sensor 6 is installed on the sensor installation position 7, and the temperature sensor 6 is used to be connected to the control module of the inkjet device.

[0056] Among them, the temperature sensor 6 is used to collect the ink temperature of the ink in the ink cartridge cavity 5 in real time. The sensor installation position 7 includes but is not limited to being set on any one or more of the front side, rear side, left side, right side and bottom surface of the ink cartridge box 1. One or more sensor installation positions 7 can be set on each surface. The number of sensor installation positions 7 corresponds to the number of temperature sensors 6. In this embodiment, the specific number and specific position of the sensor installation positions 7 are not limited.

[0057] In one embodiment, the sensor mounting position 7 in this embodiment is a concave structure, so that the temperature sensor 6 installed on the sensor mounting position 7 is closer to the ink in the ink cartridge cavity 5, which is beneficial to improving the accuracy of the temperature sensor 6 in collecting the ink temperature.

[0058] In one embodiment, the control module of the ink cartridge heating system can obtain the ink temperature of the ink in the ink cartridge cavity 5 through the temperature sensor 6. When the temperature difference between the ink temperature and the temperature threshold exceeds the preset temperature difference threshold, the control module can control the heating temperature and heating rate of the heating rod 3 to adjust the ink temperature in the ink cartridge cavity 5; when the temperature difference between the ink temperature and the temperature threshold is within the range of the preset temperature difference threshold, the control module can control the heating temperature and heating rate of the heating rod 3 to maintain the ink temperature in the ink cartridge cavity 5.

[0059] In another embodiment, the control module of the ink cartridge heating system can obtain the ink temperature of the ink in the ink cartridge chamber 5 via the temperature sensor 6. When the temperature difference between the ink temperature and the temperature threshold exceeds a preset temperature difference threshold, the control module calculates the required heating time, corresponding heating temperature, heating rate, and other values ​​of the heating rod 3 according to the ink temperature according to a preset heating time calculation method. The control module then controls the heating rod 3 to heat the ink in the ink cartridge chamber 5 according to the heating time. When the heating time is reached, the control module controls the heating rod 3 to stop heating. The heating time calculation method includes, but is not limited to, a PID (Proportional-integral-derivative control) control method.

[0060] In a specific implementation, when the control module uses PID control to heat the ink on the heating rod, it obtains the ink temperature fed back in real time by the temperature sensor, and then calculates the temperature difference between the ink temperature and the set temperature. Then, the PID control algorithm is used to calculate the heating time of the heating rod based on the temperature difference, so as to control the heating rod to heat the ink in the ink cartridge according to the heating time. It should be understood that during the process of the heating rod heating the ink, the temperature sensor will continuously feed back the ink temperature in real time and calculate the temperature difference between the ink temperature and the set temperature. Therefore, the PID control algorithm can be used to continuously calculate the heating time of the heating rod based on the temperature difference, so as to control the heating rod to heat the ink in the ink cartridge according to the heating time, ensuring that the ink temperature of the ink in the ink cartridge is always maintained within a preset temperature range, such as a temperature range of ±0.5°C of the set temperature. This effectively solves the problem of temperature overshoot and lag.

[0061] In summary, in this embodiment, by setting a temperature sensor 6 in the ink cartridge and connecting it to the control module of the inkjet device, intelligent control of the ink cartridge heating can be achieved, avoiding overheating or underheating and improving the stability of the ink cartridge heating.

[0062] refer to Figure 2 As shown, it is a structural schematic diagram of the temperature sensor 6 in the present invention. The temperature sensor 6 includes a temperature terminal 19, a wire 20, a heat shrink tube 21 and a crimping terminal 22. The temperature terminal 19 is connected to the first end of the wire 20, the crimping terminal 22 is connected to the second end of the wire 20, the heat shrink tube 21 is sleeved on the outer surface of the wire 20, and the crimping terminal 22 is used to connect to the control module of the ink cartridge heating system.

[0063] like Figure 3 As shown, this is a structural schematic diagram of an ink cartridge box 1 disclosed in the present invention. A groove 11 is provided at the bottom of the ink cartridge cavity 5. A plurality of ink outlet interfaces 12 and waste ink interfaces 13 are provided side by side at the bottom of the groove 11. The ink outlet interface 12 is used to connect the ink cartridge cavity 5 and the inkjet head of the inkjet device.

[0064] The inkjet device in this embodiment includes but is not limited to an inkjet printer.

[0065] In specific applications, when the ink in the ink cartridge cavity 5 needs to be replaced due to expiration, poor quality, etc., the ink can be discharged from the ink cartridge cavity 5 through the waste ink interface 13, so that new ink can be added to the ink cartridge cavity 5 through the ink inlet interface 24. Therefore, by separately setting the waste ink interface 13, it is possible to avoid disassembling the inkjet head connected to the ink outlet interface 12 to discharge the ink, which is beneficial to improving the efficiency of ink replacement.

[0066] In one embodiment, the structure of the groove 11 at the bottom of the ink cartridge cavity 5 includes but is not limited to an inclined groove, a V-shaped groove, and a U-shaped groove.

[0067] In one embodiment, all ink outlet interfaces 12 are connected to the same ink jet port, or each ink outlet interface 12 is connected to a different ink jet port, which is not limited in this embodiment.

[0068] In addition, in this embodiment, a sealing groove 25 is provided at the top of the ink cartridge cavity. A rubber sealing ring is built into the sealing groove 25 to improve the sealing effect of the ink cartridge.

[0069] To sum up, in this embodiment, by providing a groove 11 at the bottom of the ink cartridge cavity 5, when the amount of ink in the ink cartridge cavity 5 is small, the ink can be always concentrated at the bottom of the groove 11 due to the influence of gravity. By providing an ink outlet interface 12 at the bottom of the groove 11, the ink can always be concentrated at the position of the ink outlet interface 12, thereby reducing the fluidity of the ink in the ink cartridge cavity 5, thereby achieving the purpose of improving the ink utilization rate.

[0070] like Figure 4 , which is a perspective structural diagram of an ink cartridge disclosed in the present invention, a liquid level baffle 14 is provided in the ink cartridge cavity 5 , the bottom end of the liquid level baffle 14 extends into the ink cartridge cavity 5 , and the liquid level baffle 14 is provided with a guide hole 15 .

[0071] In one embodiment, one or more liquid level baffles 14 may be provided in the ink cartridge chamber 5 , and each liquid level baffle 14 may be provided with one or more guide holes 15 .

[0072] In one embodiment, the top end of the liquid level baffle 14 can be connected to the bottom surface of the ink cartridge cover 2, and the bottom end of the liquid level baffle 14 extends into the ink cartridge cavity 5, wherein the connection method between the liquid level baffle 14 and the bottom surface of the ink cartridge cover 2 includes but is not limited to a snap connection, a screw connection, a rivet connection, etc.

[0073] In another embodiment, the liquid level baffle 14 can be installed in the ink cartridge cavity 5. For example, the liquid level baffle 14 can be installed on the side wall and / or bottom of the ink cartridge cavity 5. The installation method of the liquid level baffle 14 and the side wall and / or bottom of the ink cartridge cavity 5 includes but is not limited to snap connection, screw connection, rivet connection, etc.

[0074] To sum up, in this embodiment, by setting a liquid level baffle in the ink cartridge, drastic fluctuations of the ink in the ink cartridge cavity can be avoided, which is beneficial to improving the stability of the ink in the ink cartridge cavity and further ensuring the stability of the ink ejected by the inkjet head of the inkjet device.

[0075] In one embodiment, the shape of the guide hole 15 on the liquid level baffle 14 includes but is not limited to a square, a rectangle, an oblong, an elongated circle, etc. In this embodiment, the shape and size of the guide hole 15 are not limited.

[0076] refer to Figure 1 、 Figure 3 and 4 As shown, the ink cartridge in this embodiment further includes a float switch 16. The ink cartridge cover 2 is provided with a float mounting hole 17. A first end of the float switch 16 is mounted in the float mounting hole 17, and a second end of the float switch 16 extends into the ink cartridge cavity 5. The float switch 16 is used to detect the ink level in the ink cartridge cavity 5.

[0077] In one embodiment, the first end of the float switch 16 and the float mounting hole 17 can be screw-mounted or snap-mounted. In this embodiment, the mounting method between the first end of the float switch 16 and the float mounting hole 17 is not limited.

[0078] In one embodiment, the second end of the float switch 16 in this embodiment can contact the bottom of the ink cartridge cavity 5, or the second end of the float switch 16 in this embodiment can be close to the bottom of the ink cartridge cavity 5. In this embodiment, there is no limitation on the depth to which the second end of the float switch 16 extends into the ink cartridge cavity 5.

[0079] It is understandable that in this embodiment, the float switch 16 can be used to detect the ink level in the ink cartridge chamber 5 in real time, thereby reminding the staff to refill the ink cartridge in time, thereby avoiding the situation of invalid ink jetting.

[0080] refer to Figure 1 or Figure 4 As shown, the ink cartridge cover 2 in this embodiment is provided with a negative pressure interface 18, which is used to connect to a negative pressure gas source.

[0081] It can be understood that connecting the ink cartridge chamber 5 with the negative pressure gas source through the negative pressure interface 18 is beneficial to increasing the negative pressure intensity in the ink cartridge chamber 5, thereby increasing the inkjet intensity of the inkjet device's inkjet port.

[0082] In addition, the ink cartridge cover 2 in this embodiment may also include one or more spare negative pressure interfaces 18 to avoid the situation where the negative pressure in the ink cartridge chamber is reduced due to blockage of one negative pressure interface 18, or, by increasing the negative pressure air source for the ink cartridge through multiple negative pressure interfaces, the negative pressure strength of the ink cartridge chamber can be further improved.

[0083] refer to Figure 5 As shown, this is a schematic structural diagram of a heating rod 3 disclosed in the present invention. The heating rod 3 includes a heat-conducting rod 8, a high-temperature wire 9, and a high-temperature sleeve 10. The heat-conducting rod 8 is connected to a first end of the high-temperature wire 9, and a second end of the high-temperature wire 9 is connected to a control module of the ink cartridge heating system. The high-temperature sleeve 10 is sleeved on the outer surface of the high-temperature wire 9.

[0084] refer to Figure 1 or Figure 4 As shown, the ink cartridge in this embodiment further includes a heat-insulating layer 23 , which covers the outer surfaces of the ink cartridge box 1 and the ink cartridge cover 2 .

[0085] It can be seen that in this embodiment, the heat insulation layer 23 can reduce the heat loss rate in the ink cartridge, avoid frequent heating of the ink cartridge, and improve the heating efficiency of the ink cartridge.

[0086] like Figure 6 , which is a circuit diagram of an ink cartridge heating system disclosed in an embodiment of the present invention. The ink cartridge heating system is applied to the ink cartridge disclosed in any of the above embodiments. The ink cartridge heating system includes a control module and a heating rod, which is electrically connected to the control module.

[0087] In the specific implementation, the control module in this embodiment is used to obtain the ink temperature collected by the temperature sensor in real time. When the ink temperature is lower than the set temperature, the temperature difference between the ink temperature and the set temperature is calculated, and then the heating time of the heating rod is calculated based on the temperature difference through the PID algorithm. Then, the heating rod is controlled to heat the ink in the ink cartridge according to the heating time. When the heating time is reached, the heating rod is controlled to stop heating the ink in the ink cartridge.

[0088] In one embodiment, reference Figure 6 As shown, the control module in this embodiment includes a power module, a controller and a relay, a first end of the relay is connected to the output end of the controller, a second end of the relay is connected to the power module, and a third end of the relay is connected to the heating rod;

[0089] When the output terminal of the controller outputs a heating signal to the first terminal of the relay, the relay connects the electrical connection between the power module and the heating rod, so that the power module can supply power to the heating rod to heat the ink in the ink cartridge;

[0090] When the output end of the controller stops outputting the heating signal, the relay cuts off the electrical connection between the power module and the heating rod, causing the power module to stop supplying power to the heating rod.

[0091] The first end of the relay is a control end of the relay, and the control end is used to control whether the second end and the third end of the relay are connected.

[0092] In one embodiment, the relay in this embodiment is preferably a solid-state relay. Compared with ordinary relays, solid-state relays can effectively avoid machine noise caused by frequent starting and stopping of relays, and solid-state relays have faster starting and stopping speeds and frequencies than ordinary relays, which can better ensure the heating efficiency of ink, thereby ensuring the stability of the solder mask process and the quality of the produced products.

[0093] In one embodiment, the ink cartridge heating system in this embodiment further includes a temperature sensor, and an output end of the temperature sensor is connected to an input end of the controller.

[0094] In actual applications, the controller in this embodiment is used to obtain the ink temperature collected by the temperature sensor in real time. When the ink temperature is lower than the set temperature, the temperature difference between the ink temperature and the set temperature is calculated, and then the heating time of the heating rod is calculated based on the temperature difference through the PID algorithm. Then, according to the heating time, the relay is controlled to switch to the on state so that the power module can supply power to the heating rod to heat the ink in the ink cartridge. When the heating rod reaches the heating time, the control relay is switched to the off state to stop the heating rod from heating the ink in the ink cartridge.

[0095] As an extension, in this embodiment, there can be multiple relays and multiple heating rods, and each relay can be connected to one or more heating rods. In this embodiment, there is no limitation on the number of relays, the number of heating rods, and the number of relays connected to heating rods.

[0097] The ink cartridge includes: an ink cartridge box and an ink cartridge cover;

[0098] The ink cartridge box includes a plurality of heating holes, each of which is equipped with a heating rod, and each heating rod is connected to a control module of the ink cartridge heating system;
