Description

Technical Field

[0001] This utility model relates to printing consumables, and in particular to an ink cartridge. Background Technology

[0002] Reference Figure 1 and Figure 2 This describes an existing color printing device with an ink cartridge compartment 1 and corresponding ink cartridges. The ink cartridge compartment 1 needs to accommodate ink cartridges of different colors to achieve color printing. To prevent incorrect ink cartridge installation, the printing device has color card detection mechanisms 2 at the different color ink cartridge installation positions in the ink cartridge compartment 1, with each color card detection mechanism 2 corresponding to a specific color ink cartridge. The color card detection mechanism 2 includes a color card detection element 21 and a blocking element 22, and the ink cartridge has a color card structure 3. The blocking element 22 is located on one side of the ink suction nozzle 11 in the ink cartridge compartment 1 and can prevent the ink outlet 110 of the ink cartridge from engaging with the ink suction nozzle 11. When the correct color ink cartridge is installed in the correct ink cartridge installation position, the color card detection element 21 and the color card structure 3 of the ink cartridge match and engage. The color card detection element 21 can be activated or the blocking element 22 can be moved away from the position blocking the ink outlet 110, thus allowing the ink cartridge to be installed correctly. When an ink cartridge of the wrong color is installed in the wrong ink cartridge mounting position, the color card detection component 21 cannot match the color card structure 3 of the ink cartridge, so the blocking component 22 cannot be moved, and the ink cartridge cannot be installed normally, thus ensuring that the ink cartridge is not installed incorrectly.

[0003] However, the aforementioned printing equipment requires the use of ink cartridges with the aforementioned special structure, which limits the types and specifications of ink cartridges that can be selected by the printing equipment, making daily use inconvenient and costly. In addition, ink cartridge manufacturers need to produce a wide variety of ink cartridges with color card structure 3 to match different colors, resulting in high production and storage costs.

[0023] Reference Figures 1 to 2 This refers to the ink cartridge compartment 1 and the corresponding ink cartridge of an existing color printing device.

[0024] Reference Figures 3 to 6 An ink cartridge, installable in an ink cartridge compartment 1 equipped with a color card detection mechanism 2, includes a cartridge body 100 and a push head 200. The cartridge body 100 has an ink outlet 110, an ink storage chamber 120, and a color card detection clearance part 130. The ink storage chamber 120 stores ink, and the ink outlet 110 has an ink outlet channel 111 communicating with the ink storage chamber 120. The cartridge body 100 is at least partially transparent, allowing observation of the ink in the ink storage chamber 120 and / or the ink outlet channel 111. The color card detection clearance part 130 avoids the color card detection element 21 of the color card detection mechanism 2. The push head 200 is disposed in the ink outlet 110 and is used to push open the blocking element 22 of the color card detection mechanism 2 when the ink cartridge is installed in the ink cartridge compartment 1, so that the ink outlet 110 can engage with the ink suction nozzle 11 of the ink cartridge compartment 1.

[0025] The aforementioned ink cartridge allows the user to observe the ink color within the ink reservoir 120 or ink outlet channel 111 through a transparent structure. This enables the user to install the cartridge into the corresponding color slot in the ink cartridge compartment 1. During installation, the ink cartridge yields to the color card detection sensor 21 via the color card detection clearance part 130, preventing the sensor from being triggered. Simultaneously, the push head 200 pushes aside the blocking member 22, allowing the ink outlet 110 and the ink suction nozzle 11 of the ink cartridge compartment 1 to engage. The ink suction nozzle 11 can then draw ink from the ink outlet channel 111, completing the cartridge installation. This ink cartridge can be installed in an ink cartridge compartment 1 equipped with a color card detection mechanism 2, ensuring correct installation by observing the ink color. This increases the selection of ink cartridges for printing devices and reduces operating costs. Furthermore, the aforementioned ink cartridge eliminates the need for a color card structure 3, avoiding the production of numerous ink cartridges with a wide variety of color card structure 3 specifications, thus helping ink cartridge manufacturers reduce production and storage costs.

[0026] In this embodiment, the color card detection clearance portion 130 is specifically a recessed and default portion of the box body 100, which allows the color card detection component 21 to be cleared.

[0027] In this embodiment, the ink cartridge is inserted into the ink cartridge compartment 1. The push head 200 is provided with a guide part 210, which guides the blocking member 22 of the color card detection mechanism 2 to be pushed open during the insertion and installation of the ink cartridge. With the above structure, the blocking member 22 is pushed open by the guide part 210 during the insertion and installation of the ink cartridge, resulting in a smooth and gentle action and better protection for each component.

[0028] In this embodiment, the guide portion 210 is a chamfered surface formed on the four edges of the end of the push head 200 along the insertion direction. With the above structure, by setting the guide portion 210 as the chamfered surface on the four edges of the end of the push head 200, the push head 200 essentially forms a conical head, thereby facilitating the opening of the blocking member 22. In this embodiment, the ink cartridge is inserted and installed in the ink cartridge compartment 1, thus the guide portion 210 is located at the front end of the push head 200.

[0029] In this embodiment, the push head 200 and the cartridge body 100 are separately configured. The push head 200 includes an installation section 220 and a guide section 230. The guide section 230 is connected to one end of the installation section 220, and a guide part 210 is disposed on the guide section 230. The installation section 220 is provided with a socket hole 221 and is sleeved and installed on the ink outlet section 110. The guide section 230 is provided with a clearance through hole 231, which communicates with the socket hole 221.

A limiting part 140 is provided at the upper rear end of the cartridge body 100. The limiting part 140 cooperates with the ink cartridge compartment 1 and limits the forward installation depth of the upper part of the cartridge body 100. With this structure, the installation of the ink outlet 110 and the ink suction nozzle 11 can limit the installation depth of the lower part of the ink cartridge. By further providing the limiting part 140, the installation depth of the upper part of the ink cartridge can be limited, thereby preventing the overall installation from being too deep. In this embodiment, a handle groove 150 is provided at the upper rear end of the cartridge body 100, allowing for convenient removal of the ink cartridge from the ink cartridge compartment 1.

[0033] In this embodiment, a handle portion 160 is adjacent to the rear side of the handle groove 150, and the handle portion 160 forms the rear wall of the handle groove 150. The upper end of the handle portion 160 extends to the left and right sides to form protrusions 161. Step portions 170 are respectively provided at positions where the cartridge body 100 and the two protrusions 161 are vertically opposite each other. A cover engagement position 180 is formed between the protrusions 161 and the corresponding step portions 170. With the above structure, the handle portion 160 can be used as a handle to facilitate the removal of the ink cartridge. On the other hand, the handle portion 160 forms a T-shaped structure, which can utilize the space formed between the protrusions 161 and the corresponding step portions 170 to cooperate with the cover of the ink cartridge compartment 1, thereby simplifying the structure.

[0034] In one embodiment, an anti-slip portion is provided on the inner wall of the handle portion 160 near the handle groove 150 to prevent slippage during operation. In another embodiment, the anti-slip portion may be an anti-slip stripe integrally formed with the handle portion 160.

[0035] In this embodiment, the cartridge body 100 includes a main shell 101 and a cover 102. The main shell 101 is provided with an ink reservoir, and the cover 102 is connected to the main shell 101 and seals the opening of the ink reservoir. The cover 102 and the main shell 101 together form an ink storage cavity 120. The ink outlet 110 is integrally formed with the main shell 101, and both the main shell 101 and the ink outlet 110 are transparent. By adopting the above structure, the entire main shell 101 and the ink outlet 110 are made transparent, thereby allowing for easy observation of the ink color.

[0036] It is conceivable that in other embodiments, transparent structures may also be provided in other parts, such as a transparent structure on the faceplate 102, which can be configured according to the actual situation by those skilled in the art.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
