Description

Technical Field

[0001] This application relates to the field of printing technology, and more particularly to an ink cartridge. Background Technology

[0002] The ink used in the printing devices of related technologies contains volatile substances. During the printing process, these volatile substances in the ink that has not yet dried or in the printed image on the printing medium will evaporate into the air inside the printer, thus generating printing exhaust gas. This printing exhaust gas has an unpleasant odor and poses a certain degree of adverse health effects to users. Utility Model Content

[0003] In view of this, this application provides an ink cartridge that can reduce printing exhaust gas generated during the printing process.

[0004] This application provides an ink cartridge for a mounting structure that can be detachably installed in a printing device. The ink cartridge includes a housing and an exhaust gas adsorption component. The housing is provided with an ink storage cavity and an ink outlet. The ink storage cavity is connected to the outside of the housing through the ink outlet. The housing is also provided with a receiving cavity and an open opening. At least a portion of the exhaust gas adsorption component is located in the receiving cavity. The receiving cavity is connected to the outside of the housing through the open opening. The housing also includes a partition portion that separates the receiving cavity and the ink storage cavity.

[0005] When the ink cartridge, including the exhaust gas adsorption component, is inside the printing unit, the printing exhaust gas generated during the printing process can enter the exhaust gas adsorption component located in the receiving cavity through the open port. This means the printing exhaust gas can be adsorbed by the adsorption component, resulting in a relatively small amount of printing exhaust gas being discharged from inside the printing unit to the outside. Users will notice less odor when using the printing unit, thus posing less health risk.

[0088] In the accompanying diagram, directions X, Y, and Z are perpendicular to each other.

[0089] This application provides some embodiments of ink cartridges for use in mounting structures (also known as cartridge cases) that are detachably mounted on a printing device.

[0090] In some embodiments, please refer to Figure 1 As shown, the printing device 20 includes a main body 201, a mounting structure 202, a slide rail 203, and a cover 204. The slide rail 203 is fixedly mounted on the main body 201, the cover 204 is rotatably connected to the main body 201, and the mounting structure 202 is slidably connected to the slide rail 203. When the ink cartridge 10 is mounted on the mounting structure 202, the cover 204 can be closed onto the main body 201. After the printing device is started, please refer to... Figure 2As shown, the mounting structure 202 can slide relative to the slide rail 203 in the extension direction of the slide rail 203 (the direction parallel to direction K), so the mounting structure 202 can also be called a word car.

[0091] In other embodiments (not shown in the figures), the mounting structure may also be fixedly mounted on the main body of the device.

[0092] In some embodiments, please refer to Figures 3-4 As shown, the mounting structure 202 has a front end and a rear end. The mounting structure 202 includes a snap-fit ​​structure 2021, which includes a front snap-fit ​​structure 2021a and a rear snap-fit ​​structure 2021b. The front snap-fit ​​structure 2021a is located at the front end of the mounting structure 202, and the rear snap-fit ​​structure 2021b is located at the rear end of the mounting structure 202. When the ink cartridge 10 is installed in the mounting structure 202, the snap-fit ​​structure 2021 snaps into the ink cartridge 10 to prevent the ink cartridge 10 from detaching from the mounting structure 202.

[0093] In some embodiments, please refer to Figures 5-6 As shown, the ink cartridge 10 includes a housing 1, which includes a top structural wall 1a, a bottom structural wall 1b, and side structural walls. The side structural walls include a first side structural wall 1c, a second side structural wall 1d, a third side structural wall 1e, and a fourth side structural wall 1f. The top structural wall 1a and the bottom structural wall 1b are spaced apart in the height direction of the housing 1 (parallel to the Z direction), the first side structural wall 1c and the second side structural wall 1d are spaced apart in the length direction of the housing 1 (parallel to the X direction), and the third side structural wall 1e and the fourth side structural wall 1f are spaced apart in the width direction of the housing 1 (parallel to the Y direction).

[0094] In some embodiments, please refer to Figure 7 As shown, the ink cartridge 10 also includes a chip 5 (also known as a circuit board or storage medium). The chip 5 can be disposed on the first side structural wall 1c. The chip 5 can contact and be electrically connected to the stylus of the printing device, so that the printing device can read the information in the chip 5 and write the information into the chip 5.

[0095] In some embodiments, please refer to Figures 5-7 As shown, the housing 1 may be provided with a snap-fit ​​structure 19, which includes a front snap-fit ​​structure 191 and a rear snap-fit ​​structure 192. The front snap-fit ​​structure 191 is disposed on the first side structural wall 1c, and the rear snap-fit ​​structure 192 is disposed on the second side structural wall 1d.

[0096] In some embodiments, please refer to Figure 8As shown, when the ink cartridge 10 is installed on the mounting structure 202, the front latching structure 191 can latch with the front latching structure 2021a, and the rear latching structure 192 can latch with the rear latching structure 2021b. The front latching structure 191 includes a protruding structure, and the front latching structure 2021a includes a recessed structure. The latching is achieved through the cooperation of the protruding and recessed structures. Similarly, the rear latching structure 192 includes a protruding structure, and the rear latching structure 2021b includes a recessed structure. The latching is achieved through the cooperation of the protruding and recessed structures.

[0097] In other embodiments (not shown in the figures), the front snap-fit ​​structure may include a recessed structure, and the front snap-fit ​​structure may include a protruding structure. Similarly, the rear snap-fit ​​structure may include a recessed structure, and the rear snap-fit ​​structure may include a protruding structure.

[0098] In some embodiments, please refer to Figure 9 As shown, the housing 1 may be provided with an ink outlet 13, which may be located on the bottom structural wall 1b.

[0099] In some embodiments, please refer to Figure 9 As shown, the housing 1 may be provided with an air inlet 14, which may be located on the bottom structural wall 1b.

[0100] In some embodiments, please refer to Figure 9 As shown, an air inlet chamber 15 can be provided inside the housing 1, and an air inlet hole 14 communicates with the air inlet chamber 15. The housing 1 is also provided with an air guide channel 16, through which the air inlet chamber 15 communicates with the ink storage chamber 11. In this configuration, when the ink (also known as ink) in the ink storage chamber 11 flows to the outside of the housing 1 through the ink outlet 13, the gas outside the housing 1 can enter the air inlet chamber 15 through the air inlet hole 14, and then the gas enters the ink storage chamber 11 from the air inlet chamber 15 through the air guide channel 16 to balance the internal air pressure of the ink storage chamber 11, so that the ink can flow smoothly from the ink storage chamber 11 to the outside of the housing 1 through the ink outlet 13 to successfully complete the corresponding printing work.

[0101] In some embodiments, please refer to Figure 9As shown, the air guide channel 16 can be disposed on the top structural wall 1a. The air guide channel 16 includes a first air guide hole 161, an air guide groove 162, and a second air guide hole 163 that are connected to each other. The first air guide hole 161 penetrates through the top structural wall 1a and can communicate with the air inlet chamber 15. The air guide groove 162 is recessed in the top structural wall 1a. The second air guide hole 163 penetrates through the top structural wall 1a and can communicate with the ink storage chamber 11. Therefore, the gas located in the air inlet chamber 15 can enter the ink storage chamber 11 through the first air guide hole 161, the air guide groove 162, and the second air guide hole 163. In some embodiments, the ink cartridge may also include a diaphragm (not shown in the figure), which (also called an air-sealing membrane) separates the air guide groove 162 from the outside of the housing 1, so that the air guide groove 162 is mainly connected to the first air guide hole 161 and the second air guide hole 163.

[0102] In some embodiments, please refer to Figure 9 As shown, the ink storage chamber 11 includes a main ink storage chamber 111 and a buffer chamber 112 that are connected to each other. Both the main ink storage chamber 111 and the buffer chamber 112 are used to store ink. The main ink storage chamber 111 may include a first chamber 111a and a second chamber 111b that are connected to each other and used to store ink. The second air vent 163 is connected to the buffer chamber 112, and the buffer chamber 112 is connected to the ink outlet 13.

[0103] In some embodiments, please refer to Figure 9 As shown, the housing 1 may be provided with an outlet cavity 12, and the buffer chamber 112 is connected to the ink outlet 13 through the outlet cavity 12.

[0104] In some embodiments, please refer to Figure 10 As shown, the ink cartridge also includes a flow restrictor 6 (such as a porous material like sponge or felt). The flow restrictor 6 is located in the buffer chamber 112. The flow restrictor 6 can limit the flow of ink from the main ink storage chamber 111 to control the flow rate of ink from the ink outlet 13.

[0105] In some embodiments, please refer to Figure 10 As shown, the ink cartridge also includes a filler 7, which is located in... Figure 9 The filling material 7 in the outlet cavity 12 shown can also be made of a porous material such as sponge or felt. The filling material 7 guides the ink in the buffer chamber 112 to the ink outlet 13 through capillary action, and the capillary force of the filling material 7 is stronger than the capillary force of the flow restrictor 6.

[0106] Printing devices generate printing exhaust gases when performing inkjet printing. These gases primarily consist of volatile organic compounds (VOCs) found in the ink, such as glycols (e.g., ethylene glycol), glycol ethers (e.g., propylene glycol ether), and may also include benzene compounds, esters, and ketones. Printing exhaust gases have a strong odor and pose a certain degree of health risk to users.

[0107] In some embodiments, please refer to Figure 9 As shown, the housing 1 also includes a receiving cavity 17 and an opening 18, through which the receiving cavity 17 communicates with the outside of the housing 1. Please refer to... Figure 10 As shown, the ink cartridge 10 also includes a waste gas adsorption component 2, at least a portion of which may be located within the receiving cavity 17.

[0108] In some embodiments, when the ink cartridge 10, including the exhaust gas adsorption element 2, is inside the printing device, the printing exhaust gas generated during the printing process can enter the exhaust gas adsorption element 2 located in the receiving cavity 17 from outside the housing 1 through the opening 18. That is, the printing exhaust gas can be adsorbed by the exhaust gas adsorption element 2, so that the amount of printing exhaust gas that can be discharged from inside the printing device to the outside of the printing device is relatively small. The user can smell less odor gas when using the printing device, and the degree of harm to the user's health is relatively small.

[0109] When the mounting structure of the printing device is equipped with multiple ink cartridges including exhaust gas adsorption components, the adsorption effect on printing exhaust gas is better.

[0110] In some embodiments, when the mounting structure of the printing device moves relative to the main body of the device, the ink cartridge mounted on the mounting structure also moves relative to the main body of the device, and the exhaust gas adsorption component located on the ink cartridge also moves relative to the main body of the device. Therefore, the exhaust gas adsorption component can adsorb printing exhaust gas from multiple locations within the printing device, resulting in relatively high adsorption efficiency.

[0111] In some embodiments, since the ink cartridge integrates a waste gas adsorption component capable of adsorbing waste gas, the adsorption component that has adsorbed a significant amount of printing waste gas can be replaced along with the used ink cartridge during routine replacement. That is, when a new ink cartridge is placed in the mounting structure, the new adsorption component is also placed inside the printing device. Correspondingly, the printing device may not need to have a component for adsorbing waste gas, simplifying the device's structure and eliminating the need for the cumbersome process of specifically replacing consumables for adsorbing printing waste gas within the printing device.

[0112] The exhaust gas adsorption component 2 can be located entirely within the receiving cavity 17, or it can extend from the receiving cavity 17 to the outside of the housing 1 through the opening 18. At least a portion of the structure of the exhaust gas adsorption component 2 is located within the receiving cavity 17 of the housing 1, so that the exhaust gas adsorption component 2 does not occupy the external space of the housing 1, or the external space occupied by the exhaust gas adsorption component 2 is relatively small. Therefore, the ink cartridge 10 including the exhaust gas adsorption component 2 occupies relatively little space in the printing device, and the ink cartridge 10 including the exhaust gas adsorption component 2 has good compatibility.

[0113] Furthermore, the structure of the waste gas adsorption element can include at least one of the following: granular structure, sheet structure, and block structure. The material of the waste gas adsorption element can be at least one of the following: activated carbon granules, activated carbon fiber products, etc., all of which possess a porous structure and good adsorption properties.

[0114] Optionally, in some embodiments, the opening 18 is disposed on the first structural wall of the housing 1, and the ink outlet 13 is disposed on the second structural wall of the housing 1. In this configuration, the opening 18 is far from the ink outlet 13, so even if ink flows out of the ink outlet 13, the ink is unlikely to flow to the opening 18, and the ink is unlikely to come into contact with the waste gas adsorption element, thus reducing the likelihood of deterioration in the adsorption performance of the waste gas adsorption element. Therefore, the probability of the waste gas adsorption element coming into contact with ink and the probability of adsorption performance deterioration and failure are relatively low.

[0115] The first structural wall can be the top structural wall 1a, and the second structural wall can be the bottom structural wall 1b. Please refer to [reference needed]. Figure 9 As shown, the open port 18 can be set on the top structural wall 1a, and the ink outlet 13 can be set on the bottom structural wall 1b. The probability of the ink flowing out of the ink outlet 13 flowing to the open port 18 is relatively low.

[0116] Furthermore, since the top structural wall 1a is not surrounded by the mounting structure 202, and there is a gap between the top structural wall 1a and the cover (not shown in the figure), when the opening 18 is provided in the top structural wall 1a, the printing exhaust gas in the printing device can smoothly enter the receiving cavity 17 through the gap and the opening 18, thereby making it easier for the printing exhaust gas to be adsorbed by the exhaust gas adsorption component.

[0117] In other embodiments (not shown in the figure), the first structural wall can be a top structural wall and the second structural wall can be a side structural wall, that is, the opening can be provided on the top structural wall and the ink outlet can be provided on the side structural wall.

[0118] Alternatively, please refer to Figure 9 As shown, the receiving cavity 17 is recessed in the top structural wall 1a. Under this configuration, please refer to... Figure 10As shown, the exhaust gas adsorption component 2 may not protrude excessively relative to the top structural wall 1a. Therefore, the ink cartridge 10 including the exhaust gas adsorption component 2 occupies relatively little space inside the printing device, and the ink cartridge 10 including the exhaust gas adsorption component 2 has good compatibility.

[0119] Please refer to Figure 9 As shown, the entire receiving cavity 17 can be exposed to the outside of the housing 1 through a large open area 18, meaning that the upper part of the receiving cavity 17 is not obstructed by the structure of the housing 1. With this configuration, the communication area between the receiving cavity 17 and the outside of the housing 1 through the open area 18 is relatively large. Therefore, the amount of printing exhaust gas that the exhaust gas adsorption component 2 located in the receiving cavity 17 can contact and adsorb per unit time is relatively large, thus possessing the advantage of high adsorption efficiency.

[0120] In other embodiments, the structure of the receiving cavity 17 and the opening 18 can also be as follows. Figure 11 As shown. In Figure 11 In the middle, the receiving cavity 17 is connected to the outside of the shell through a relatively small opening 18. Part of the receiving cavity 17 is covered by the covering part 178 of the shell 1. The covering part 178 can play a good limiting role for the exhaust gas adsorption element located in the receiving cavity 17.

[0121] In other embodiments (not shown in the figures), the receiving cavity may also be embedded in other locations within the housing, as long as the receiving cavity can communicate with the outside of the housing through an opening.

[0122] When the exhaust gas adsorption element includes a sheet-like structure, a block-like structure, or a bag-like structure, the housing may also include a limiting part, which is disposed on the inner wall of the receiving cavity, and the limiting part can restrict the exhaust gas adsorption element from leaving the receiving cavity.

[0123] Optionally, the limiting part can satisfy setting a, please refer to Figure 12 As shown, in setting a, the limiting part 171 and the exhaust gas adsorption member are pressed against each other in the X direction. Static friction can exist on the contact surface between the limiting part 171 and the exhaust gas adsorption member. The static friction can restrict the exhaust gas adsorption member from leaving the receiving cavity 17.

[0124] The limiting part 171 provided on the inner wall of the receiving cavity may include a surface with a relatively large coefficient of friction, such as a rough surface or a frosted surface, so that the static friction between the limiting part 171 and the exhaust gas adsorption component is relatively large.

[0125] Optionally, the limiting part can also satisfy setting b, in which the limiting part engages with the exhaust gas adsorption element to prevent the exhaust gas adsorption element from detaching from the receiving cavity. The limiting part may include, for example... Figure 13 The protruding structure shown protrudes relative to the inner wall of the receiving cavity 17, or the limiting portion may include, for example, Figure 14The recessed structure shown can be recessed into the inner wall of the receiving cavity 17. The protruding structure of the limiting part or the recessed structure of the limiting part can engage the exhaust gas adsorption component through structural interference to prevent the exhaust gas adsorption component from detaching from the receiving cavity.

[0126] When the exhaust gas adsorption component includes a particulate structure and is not packaged in bags or mesh, the ink cartridge may also include a cover. Please refer to [reference needed]. Figure 15 As shown, the cover 3 is provided with a vent 31. The cover 3 and the housing are detachably connected. The cover 3 can close to the open opening. The receiving cavity or the open opening can be connected to the outside of the housing through the vent 31. The exhaust gas adsorption component (not shown in the figure) is located on the side of the cover 3 facing the receiving cavity 17. In this configuration, the exhaust gas adsorption component can be confined within the receiving cavity 17 by the cover 3, but the exhaust gas adsorption component can still adsorb the printing exhaust gas located outside the housing through the vent 31.

[0127] The detachable connection between the cover 3 and the housing can include snap-fit ​​(e.g., a tongue-and-groove snap-fit), fasteners (e.g., screws or pins), adhesive bonding, or magnetic connection. When the user needs to replace the exhaust gas adsorption component, the cover 3 can be removed from the housing.

[0128] In some embodiments, please refer to Figure 9 As shown, the housing 1 may include a partition 1g that separates the receiving cavity 17 and the ink storage cavity 11 so that the receiving cavity 17 is not connected to the ink storage cavity 11, thereby preventing the waste gas adsorption component located in the receiving cavity 17 from contacting the ink in the ink storage cavity 11 and thus preventing the deterioration of the waste gas adsorption performance of the waste gas adsorption component.

[0129] Since the main ink storage chamber 111 contains a large amount of ink, it is necessary to ensure that the receiving cavity 17 and the main ink storage chamber 111 are well separated by the partition 1g.

[0130] In some embodiments, the cartridge further includes a diaphragm that separates the opening from the outside of the housing; that is, the opening is closed by the diaphragm, and the exhaust gas adsorption element is located on the side of the diaphragm facing the receiving cavity. When the cartridge is not installed in the mounting structure and is not used to adsorb printing exhaust gas, the diaphragm isolates the inside of the receiving cavity from the outside of the housing, preventing the exhaust gas adsorption element inside the receiving cavity from adsorbing some particulate matter or impurities in the air, thus minimizing the reduction in the lifespan of the exhaust gas adsorption element. When the cartridge is installed in the mounting structure and used to adsorb printing exhaust gas, the portion of the diaphragm covering the opening can be removed or punctured, allowing the exhaust gas adsorption element inside the receiving cavity to adsorb printing exhaust gas located outside the housing.

[0131] Please refer to Figure 16As shown, the diaphragm 4 can be located in the top structural wall 1a. The diaphragm 4 can separate the opening (not shown in the figure) from the outside of the shell 1. In other words, the diaphragm 4 can close the opening located in the top structural wall 1a.

[0132] Please refer to Figure 16 As shown, the diaphragm 4 can also separate the outside of the housing 1 from the air guide groove (not shown in the figure) recessed in the top structural wall 1a.

[0133] When using the ink cartridge, the part of diaphragm 4 covering the open opening can be removed or punctured, but the part of diaphragm 4 covering the air guide groove does not need to be removed or punctured.

[0134] Please refer to Figure 16 As shown, the diaphragm 4 may include an integrally formed first diaphragm 41 and a second diaphragm 42. The first diaphragm 41 can separate the opening from the outside of the housing 1, and the second diaphragm 42 can separate the air guide groove from the outside of the housing 1. When using the ink cartridge, the first diaphragm 41 can be removed or punctured, while the second diaphragm 42 remains.

[0135] Please refer to Figure 16 As shown, the diaphragm 4 may further include a tearable structure 43 located between the first diaphragm 41 and the second diaphragm 42. The tearable structure 43 may be provided with multiple through holes (rectangular or circular) spaced apart along the Y direction, or it may be provided with multiple grooves (rectangular or circular) spaced apart along the Y direction. The multiple spaced through holes or grooves make the tearable structure 43 easy to tear. Therefore, when the first diaphragm 41 is torn, the tearable structure 4 between the first diaphragm 41 and the second diaphragm 42 will be torn, while the second diaphragm 42 will not be torn off.

[0136] In other embodiments (not shown in the figures), the diaphragm separating the opening from the outside of the housing can be a first diaphragm, and the diaphragm separating the air guide groove from the outside of the housing can be a second diaphragm. The first and second diaphragms can be separately configured. When using the ink cartridge, the first diaphragm can be removed or punctured, while the second diaphragm still seals the air guide groove.

[0137] In some embodiments, the first diaphragm and the second diaphragm may be bonded to the top structural wall of the housing.

[0138] Optionally, the exhaust gas adsorption element 2 may include, for example, Figure 17The diagram shows at least two structural layers, such as a first structural layer 21, a second structural layer 22, and a third structural layer 23, stacked together. The first structural layer 21 can serve as a moisture-absorbing layer, capable of adsorbing moisture; it may include materials such as silica gel or activated alumina. The second structural layer 22 can serve as a broad-spectrum adsorption layer, used to adsorb volatile organic compounds, benzene compounds, and alcohols; it may include activated carbon fiber (ACF). The third structural layer 23 can serve as a chemisorption layer, used to adsorb formaldehyde and acidic gases; it may include zinc oxide or calcium oxide.

[0139] Please refer to Figure 17 As shown, the exhaust gas adsorption component 2 can be provided with multiple through holes 2a extending from the first structural layer 21 to the third structural layer 23, in order to increase the adsorption area of ​​the exhaust gas adsorption component 2, thereby increasing the adsorption efficiency.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
