Detailed Description
As shown in fig. 1 to 8, the present embodiment provides an ink cartridge that is suitable for use as a black ink cartridge and also as a color ink cartridge; the ink cartridge is suitable for being used as an ink cartridge with large capacity, and can also be used as an ink cartridge with other various capacities. No matter what color ink box or what capacity ink box, the ink box structure of this embodiment can all improve the ink box gas-liquid exchange, reduces the probability that ink box appears the problem such as disconnected line, disconnected china ink in the printing process.
In the related art, in order to increase the capacity of the ink cartridge, the casing of the ink cartridge may be widened and/or lengthened, and the air passage of the air guide structure of the ink cartridge is directly communicated to the chamber where the ink outlet is located. The inventor finds that the ink box has the problems of wire breakage, ink breaking and the like in the printing process, and the printing quality is influenced. The inventor researches the ink box, and adopts various methods such as optimizing the structure of the air guide one-way valve, but the printing quality of the ink box with increased capacity cannot be improved well, and the failure probability of the experiment of the ink box with larger capacity is more obvious. The inventor researches and discovers that the problems of disconnection and ink breaking of the ink box in the printing process are related to gas-liquid exchange in the shell.
Based on this, the present embodiment provides an ink cartridge, which mainly comprises a casing 100, and an ink outlet structure 200 and an air guide structure 300 disposed in the casing 100. The case 100 is for containing ink; the ink outlet structure 200 is communicated with the inner side and the outer side of the shell and provides a channel for ink in the shell 100 to flow out; the air guide structure 300 communicates the inside of the case with the outside of the case, providing a passage for air outside the case to enter the inside of the case. When the ink flows out from the ink outlet structure, air enters the inner side of the shell from the air guide structure 300, and the air-liquid balance of the ink box is kept.
The ink cartridge further includes a 1 st chamber 101 to an nth chamber 10N disposed in the housing 100, where N is an integer greater than or equal to 2, for example, N is an integer greater than or equal to 3, or N is an integer greater than or equal to 4, or N is an integer greater than or equal to 5, or N is an integer greater than or equal to 6, for example, N may be 2,3,4,5,6,7,8,9, 10, or an integer greater than 10, and a value of N may be selected according to a housing volume, an ink capacity, a cost, and the like, and is not particularly limited herein.
Wherein the nth chamber and the (N + 1) th chamber are communicated through a communication hole 110 at the bottom end of the (N + 1) th chamber, and N is an integer of 1 to N-1. For example, when N is 2, the 1 st chamber 101 and the 2 nd chamber 102 are communicated through the communication hole 110 at the bottom end of the 2 nd chamber 102; when N is 3, the 1 st chamber 101 and the 2 nd chamber 102 communicate through the communication hole 110 at the bottom end of the 2 nd chamber 102, and the 2 nd chamber 102 and the 3 rd chamber 103 communicate through the communication hole 110 at the bottom end of the 3 rd chamber 103; when N is 4, the 1 st chamber 101 and the 2 nd chamber 102 communicate through the communication hole 110 at the bottom end of the 2 nd chamber 102, the 2 nd chamber 102 and the 3 rd chamber 103 communicate through the communication hole 110 at the bottom end of the 3 rd chamber 103, and the 3 rd chamber 103 and the 4 th chamber 104 communicate through the communication hole 110 at the bottom end of the 4 th chamber 104; when N is 5, the 1 st chamber 101 and the 2 nd chamber 102 communicate through the communication hole 110 at the bottom end of the 2 nd chamber 102, the 2 nd chamber 102 and the 3 rd chamber 103 communicate through the communication hole 110 at the bottom end of the 3 rd chamber 103, the 3 rd chamber 103 and the 4 th chamber 104 communicate through the communication hole 110 at the bottom end of the 4 th chamber 104, and the 4 th chamber 104 and the 5 th chamber 105 communicate through the communication hole 110 at the bottom end of the 5 th chamber 105. And so on when N takes other integer values. Wherein the (n + 1) th chamber bottom end is a bottom end of the (n + 1) th chamber in a vertical direction when the ink cartridge is used in the printing apparatus. The communicating hole 110 at the bottom end of the (n + 1) th chamber means that the end of the communicating hole 110 communicating with the (n + 1) th chamber is arranged at a position below the middle of the bottom wall or the side wall of the (n + 1) th chamber in the vertical direction, preferably the communicating hole 110 is arranged at a position close to the bottom wall of the side wall, and since when air and ink exist in one chamber at the same time, the air is gathered at the upper end of the chamber and the ink is gathered at the lower end of the chamber under the action of gravity, the structure can enable the air to enter the next chamber after the ink in each chamber is basically discharged. The communication hole 110 is communicated with the nth chamber and the (n + 1) th chamber, the first end of the communication hole is communicated with the bottom end of the (n + 1) th chamber, and the second end of the communication hole can be communicated with the bottom end of the nth chamber, at the moment, the bottom end of the nth chamber and the bottom end of the (n + 1) th chamber can be level in the vertical direction, and the chambers with level bottom ends are beneficial to enabling the ink capacity of each chamber to be large; in other embodiments of the present invention, a height difference may also be formed between the bottom end of the nth chamber and the bottom end of the (n + 1) th chamber in the vertical direction, and the first end of the communication hole 110 may communicate with the bottom end of the (n + 1) th chamber, and the second end may communicate with a position, which is closer to the middle, of the bottom end of the nth chamber, or the top end of the bottom end of the nth chamber. When the nth chamber and the (n + 1) th chamber are communicated through the communication hole 110 at the bottom end of the (n + 1) th chamber, the positions between the nth chamber and the (n + 1) th chamber except the communication hole 110, particularly the top end of the nth chamber and the top end of the (n + 1) th chamber are not communicated and are kept sealed.
Wherein, the 1 st chamber 101 is communicated with the ink outlet structure 200, and the 1 st chamber 101 supplies ink to the outside through the ink outlet structure 200. The nth chamber 10N communicates with the air guide 300 and the nth chamber 10N receives air entering the ink cartridge from the air guide 300.
With the ink cartridge of the above embodiment, the plurality of chambers are communicated in sequence through the communication hole 110 at the bottom end of the chamber, and the plurality of chambers are communicated and connected in series through the communication hole 110 to form a gas-liquid flow path. The 1 st cavity 101 that is located the series connection head end is connected with a structure 200 that goes out black, and ink can flow out for printing device's shower nozzle confession ink through a structure 200 that goes out black from the 1 st cavity 101, and the Nth cavity 10N that is located the series connection tail end is connected with air guide structure 300, and the air in the ink horn outside can get into Nth cavity 10N from air guide structure 300, goes out black structure 200 and air guide structure 300 and is located two ends on gas-liquid circulation route respectively, and both distances are far away. During printing, ink in the 1 st chamber 101 is consumed, so that negative pressure is generated in the 1 st chamber 101 and the chambers therebehind, the ink can flow to the next chamber according to the sequence from the Nth chamber 10N to the 1 st chamber 101 so as to replenish the ink in the 1 st chamber 101, air also enters the Nth chamber 10N at the moment, and after the ink in the Nth chamber 10N is basically discharged, the air can gradually enter the next chamber through the communication hole according to the sequence from the Nth chamber 10N to the 1 st chamber 101, so that the ink in each chamber is basically discharged. By the arrangement, the phenomenon that according to the sequence from the Nth chamber 10N to the 1 st chamber 101, ink in the previous chamber is not basically discharged, air enters the next chamber firstly, and the ink in the previous chamber is blocked by gas-liquid exchange when entering the next chamber does not exist. Here, that ink is substantially discharged from a chamber means that a portion, e.g., a major portion, of the ink is discharged from the chamber, and another portion, e.g., a minor portion, of the ink may remain in the chamber. Moreover, the cross-sectional area of ink in a single cavity can be reduced by arranging the plurality of cavities, the shaking of the ink during gas-liquid exchange and printing is reduced, and the smooth degree of the gas-liquid exchange is also improved. In addition, dividing the plurality of chambers also contributes to increasing the strength of the ink cartridge. Therefore, the ink box of the embodiment can enable the gas-liquid exchange in the ink box to be smoother, experiments prove that the ink box of the embodiment can obviously improve the problems of line breaking and ink breaking during printing, and the like, and the black full-coverage document is continuously printed for 20 pages at high speed, and the phenomenon of line breaking and ink breaking does not occur in the period.
Preferably, the 1 st chamber 101 to the nth chamber 10N are adjacent in sequence, where adjacent is physically adjacent, i.e. two chambers adjacent in sequence are also adjacent in physical structure, so that the communication hole 110 may be directly disposed between the adjacent two chambers, for example, may be conveniently disposed on a common wall of the adjacent two chambers, i.e. the partition 140, without forming the communication hole 110 by an additional pipe or a bent duct inside the housing.
Preferably, each two adjacent chambers are arranged in a manner independently selected from the group consisting of being arranged in a first direction and being arranged in a second direction, the first direction and the second direction being perpendicular to each other. The first direction may be a width direction of the housing, and the second direction may be a length direction of the housing. For example, when N is 3, the 1 st chamber 101 and the 2 nd chamber 102 may be aligned in the second direction, and the 2 nd chamber 102 and the 3 rd chamber 103 may be aligned in the first direction; when N is 5, the 1 st chamber 101 and the 2 nd chamber 102 may be arranged in a forward direction of the second direction, the 2 nd chamber 102 and the 3 rd chamber 103 may be arranged in the first direction, and the 3 rd chamber 103, the 4 th chamber 104, and the 5 th chamber 105 may be arranged in a reverse direction of the second direction, forming two rows. The chamber combination with different arrangement modes can be obtained by dividing different chambers in the length direction and/or the width direction of the shell. In some embodiments, the first direction, the second direction, and the vertical direction are perpendicular to each other two by two when the ink cartridge is used in a printing apparatus.
Preferably, the 1 st chamber 101 to the nth chamber 10N are arranged to form at least two chamber rows 120 arranged in parallel in a first direction, e.g., a width direction of the housing 100, to divide the housing 100 into a plurality of rows in the first direction, e.g., the width direction. The at least one chamber row 120 includes at least two chambers arranged along a second direction, e.g., a length direction of the housing 100, and the at least one chamber row 120 is divided into a plurality of chambers along the second direction, e.g., the length direction, and in some embodiments, each chamber row 120 may include at least two chambers arranged along the second direction, e.g., the length direction of the housing 100. The arrangement can ensure that the chambers are regularly arranged and are convenient to manufacture. More preferably, the chambers in a chamber row 120 are aligned with the chambers of an adjacent chamber row 120. Two adjacent chambers respectively located at the same ends of two adjacent chamber rows 120 are communicated through the communication holes 110, and the communication of the chambers between the rows is realized. The number of rows 120 of chambers may be 2,3, or greater than 3; the number of chambers per chamber row 120 may be 1,2,3 or greater than 3.

The width of the second chamber row 120 is the total width of the housing minus the width and wall thickness of the first chamber row 120. The arrangement makes the width of the chambers of the first chamber row 120, including the 1 st chamber 101 and other chambers close to the 1 st chamber in sequence, moderate, and the gas-liquid exchange is more stable.
Preferably, the ink outlet structure 200 includes an ink outlet portion 210 exposed to the housing and an ink outlet 220 disposed on the ink outlet portion 210, the ink outlet portion 210 may be connected to the bottom end of the housing 100 and extend outward from the housing 100, the ink outlet portion 210 may be used to connect an ink fetching mechanism of the printing apparatus, and the ink outlet 220 leads to the outside of the ink cartridge, that is, the ink outlet 220 communicates the first chamber 101 and the outside of the ink cartridge, so as to realize ink outlet from the first chamber 101. Before the ink cartridge is installed in the printing apparatus, the ink outlet portion 210 may be connected to a sealing member, which seals the ink outlet portion to prevent ink leakage. The air guide structure 300 includes an air guide hole 310, the air guide hole 310 passes through the ink outlet 210 and leads to the outside of the ink cartridge, the air guide hole 310 is disposed near the ink outlet 220, so that when the sealing member closes the ink outlet 220, the air guide hole 310 can be closed at the same time, the sealing property of the ink cartridge is ensured, and when the ink cartridge is mounted to a printer, the sealing member is opened to open the ink outlet 220 and the air guide hole 310 at the same time. It can be seen that the above structure facilitates the simultaneous closing and opening of the ink outlet 220 and the air guide hole 310.
Preferably, the air guide structure 300 further includes an air guide cavity 320 disposed in the casing 100 and communicated with the air guide hole 310, the air guide cavity 320 is adjacent to the 1 st chamber 101, so that the air guide hole 310 does not need to extend too long and has a simple duct from the air guide cavity 320 to the ink outlet portion 210, for example, the air guide hole 310 may communicate with the air guide cavity 320 at one end and pass through the ink outlet portion 210 at the other end in the vertical direction, and the ink outlet portion 210 may extend to a position corresponding to the bottom end of the air guide cavity 320 at the outer surface of the bottom end of the casing 100.
