Description

Technical Field

[0001] This utility model relates to the field of inkjet imaging technology, and in particular to an ink cartridge that can be detachably installed into an inkjet imaging device. Background Technology

[0002] An ink cartridge is a consumable that can be detachably installed into an imaging device. The ink cartridge has an air vent that is connected to the atmosphere, as well as an ink storage chamber and an ink replenishment chamber for containing ink. The ink storage chamber is connected to the air vent and also to the ink replenishment chamber. The ink cartridge also includes an ink supply unit for supplying ink to the imaging device. The ink supply unit includes an ink supply chamber and an ink outlet. The ink supply chamber is used to contain ink, and the ink in the ink supply chamber is supplied to the imaging device through the ink outlet. The ink storage chamber and the ink replenishment chamber are connected through the ink supply chamber.

[0003] When the ink in the ink reservoir is nearly depleted, air from the ink reservoir can enter the ink replenishment chamber, allowing the ink in the ink replenishment chamber to replenish both the ink reservoir and the ink supply chamber. However, this ink replenishment method is slow. When the imaging device has a large ink consumption requirement at one time (such as printing large color blocks), the ink in the ink replenishment chamber cannot be output stably due to the slow air replenishment speed, resulting in broken lines during printing. Utility Model Content

[0004] The ink cartridge provided by this utility model can solve at least one of the above-mentioned technical problems, and the specific technical solution is as follows:

[0005] The ink cartridge, which is detachably installed into the imaging device, includes a cover and a housing that are joined together, and an air duct, an ink reservoir, and an ink replenishment chamber formed between the cover and the housing.

[0022] Ink cartridge 100 is a consumable that can be removably installed into an imaging device, such as... Figure 1 and Figure 2 As shown, the ink cartridge 100 includes a cover plate 110 and a housing 120 that are joined together. A receiving cavity 130 is formed between the cover plate 110 and the housing 120. The receiving cavity 130 includes an air guide cavity 131, an ink storage cavity 132 and an ink replenishment cavity 133. The air guide cavity 131 is used to communicate with the atmosphere. The ink storage cavity 132 and the ink replenishment cavity 133 are used to store ink. The ink replenishment cavity 133 is used to replenish ink to the ink storage cavity 132 and the ink supply cavity 141 described below.

[0023] Figure 3 It is along Figure 1 Plan view after sectioning along the AA direction.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the ink cartridge 100 also includes an ink outlet 140 for supplying ink to the imaging device. The ink outlet 140 is connected to the housing 120. The ink outlet 140 includes an ink supply chamber 141 and an ink outlet 142 that are interconnected. The ink storage chamber 132, the ink replenishment chamber 133 and the ink supply chamber 141 are interconnected. The ink supply chamber 141 is used to contain the ink supplied to the imaging device by the ink storage chamber 132 and the ink replenishment chamber 133. The ink in the ink supply chamber 141 is supplied to the imaging device through the ink outlet 142.

[0025] With the ink cartridge 100 installed in the imaging device as a reference, the height direction of the ink cartridge 100 is the vertical direction. The cover plate 110 and the housing 120 are arranged along the vertical direction, with the cover plate 110 located above the housing 120. The direction intersecting the vertical direction is the front-back direction. The air guide cavity 131, the ink storage cavity 132, and the ink replenishment cavity 133 are arranged along the front-back direction, with the ink storage cavity 132 located in front of the ink replenishment cavity 133. The direction intersecting both the vertical and front-back directions is the left-right direction. Continuing as... Figure 1 , Figure 2 and Figure 3As shown, the housing 120 includes a bottom plate 121, a front side plate 122, a rear side plate 123, a left side plate 124, and a right side plate 125. The front side plate 122 and the rear side plate 123 are arranged opposite to each other, and the left side plate 124 and the right side plate 125 are arranged opposite to each other. The cover plate 110 and the bottom plate 121 are arranged opposite to each other in the vertical direction. The cover plate 110 is located above the bottom plate 121. The cover plate 110, the bottom plate 121, the front side plate 122, the rear side plate 123, the left side plate 124, and the right side plate 125 enclose the receiving cavity 130.

[0026] like Figure 2 and Figure 3 As shown, the cover plate 110 is provided with an air guide 111 for communicating the air guide cavity 131 with the atmosphere. In some embodiments, the air guide 111 is provided on the housing 120.

[0027] like Figure 2 and Figure 3 As shown, the ink cartridge 100 / housing 120 is also provided with a first partition plate 126 and a second partition plate 127. In the vertical direction, the first partition plate 126 and the second partition plate 127 are both located above the bottom plate 121. In the front-back direction, the first partition plate 126 and the second partition plate 127 are spaced apart. The first partition plate 126 is located between the air guide cavity 131 and the ink storage cavity 132 and is used to separate the air guide cavity 131 and the ink storage cavity 132. The second partition plate 127 is located between the ink storage cavity 132 and the ink replenishment cavity 133 and is used to separate the ink storage cavity 132 and the ink replenishment cavity 133.

[0028] Figure 4 yes Figure 3 Enlarged view of part A in the middle.

[0029] like Figure 3 and Figure 4 As shown, the first partition plate 126 is provided with a first air vent 1261, which is used to connect the air vent 131 and the ink storage chamber 132. Air in the air vent 131 can enter the ink storage chamber 132 through the first air vent 1261. The ink cartridge 100 also includes a sponge 150 for controlling the opening or closing of the first air vent 1261. The sponge 150 can absorb ink.

[0030] Figure 5 yes Figure 3 Enlarged view of section B.

[0031] like Figure 3 and Figure 5As shown, the second partition plate 127 is provided with a second air vent 1271. The second air vent 1271 is used to connect the ink storage chamber 132 and the ink replenishment chamber 133. When the liquid level in the ink storage chamber 132 is lower than the second air vent 1271, the air in the ink storage chamber 132 can enter the ink replenishment chamber 133 through the second air vent 1271, and the ink in the ink replenishment chamber 133 can replenish the ink storage chamber 132 and the ink supply chamber 141.

[0032] In some embodiments, in the vertical direction, the second air inlet 1271 is located on the side of the second partition plate 127 away from the ink supply chamber 141.

[0033] like Figure 3 As shown, in the vertical direction, the second air guide port 1271 is located above the base plate 121, or in other words, the second air guide port 1271 is located above the bottom surface of the ink storage cavity 132.

[0034] In the vertical direction, the second air guide port 1271 can be located at any position of the second partition plate 127, for example, the upper part, middle part or lower part of the second partition plate 127. In this embodiment, the second air guide port 1271 is set at the upper part of the second partition plate 127 as an example.

[0035] Continue as Figure 3 As shown, in the front-back direction, at least a portion of the second partition plate 127 is located behind the central axis M of the ink outlet 142. In other words, in the front-back direction, at least a portion of the ink replenishment chamber 133 is located behind the central axis M of the ink outlet 142. In the vertical direction, the liquid level in the ink storage chamber 132 is the same as the liquid level in the ink replenishment chamber 133. Furthermore, the projected area of ​​the ink replenishment chamber 133 in the vertical direction is smaller than the projected area of ​​the ink storage chamber 132 in the vertical direction. With this configuration, when the imaging device performs imaging work and the ink cartridge 100 moves with the printing carriage in the left-right direction, even if the ink storage chamber 132 and the ink replenishment chamber 133 move at the same speed, the ink in the ink replenishment chamber 133 will have a smaller swaying amplitude and will be less prone to generating air bubbles.

[0036] In the vertical direction, at least a portion of the second air vent 1271 is located above the first air vent 1261. After air enters the ink storage chamber 132 through the first air vent 1261, the bubbles formed will move upward in the ink and thus enter the ink replenishment chamber 133 through the second air vent 1271. In the vertical direction, since the second air vent 1271 is located above the ink supply chamber 141, the bubbles will not approach the ink supply chamber 141 when they move into the ink replenishment chamber 133. This reduces the possibility of bubbles being discharged through the ink supply chamber 141 / ink outlet 142, avoiding line breakage and affecting image quality.

[0037] [Beneficial Effects]

[0038] Compared with the prior art, the ink cartridge 100 provided by this utility model has the following beneficial effects:

[0039] Firstly, the ink cartridge 100 has a second air vent 1271 on the second partition plate 127 located between the ink storage chamber 132 and the ink replenishment chamber 133. When the liquid level in the ink storage chamber 132 is lower than the second air vent 1271, the air in the ink storage chamber 132 can enter the ink replenishment chamber 133 through the second air vent 1271. At this time, the air pressure in the ink storage chamber 132 and the ink replenishment chamber 133 is the same, and the ink in the ink replenishment chamber 133 is replenished to the ink supply chamber 141 quickly. In other words, at this time, the ink in the ink storage chamber 132 and the ink replenishment chamber 133 can be used for imaging together, which can avoid insufficient ink supply or untimely ink supply, so that the imaging quality of the imaging device is not affected.

[0040] Secondly, as described in the first aspect, when both the ink storage chamber 132 and the ink replenishment chamber 133 have a large amount of ink, the ink replenishment chamber 133 can also replenish air in a timely manner through the second air vent 1271, so that the ink in the ink replenishment chamber 133 can be consumed, thus avoiding the waste of ink in the ink replenishment chamber 133.

[0041] Thirdly, as described in the first aspect, when the imaging device has a large one-time ink consumption requirement (such as printing large color blocks), the ink in the ink replenishment chamber 133 can be quickly replenished to the ink supply chamber 141 without affecting the ink supply and avoiding the situation of printing line breakage.

[0042] Fourthly, the projected area of ​​the ink replenishment cavity 133 in the vertical direction is smaller than that of the ink storage cavity 132 in the vertical direction. Thus, when the ink storage cavity 132 and the ink replenishment cavity 133 move at the same speed, the ink in the ink replenishment cavity 133 will sway less and will be less likely to generate air bubbles.

[0043] Fifthly, in the vertical direction, at least a portion of the second air vent 1271 is located above the first air vent 1261. Furthermore, in the vertical direction, the second air vent 1271 is located above the ink supply chamber 141. After air enters the ink storage chamber 132 through the first air vent 1261, the bubbles formed will move upward in the ink and thus enter the ink replenishment chamber 133 through the second air vent 1271. Since the second air vent 1271 is located above the ink supply chamber 141, the bubbles will not enter the ink supply chamber 141, thereby reducing the possibility of air flowing through the ink supply chamber 141 / ink outlet 142.
