Description

Technical Field

[0001] The utility model relates to the technical field of ink cartridges, in particular to an ink cartridge for a printer. Background Art

[0002] A printer ink cartridge is a device used to store and release printer ink. It is a component in an inkjet printer that stores printing ink and ultimately completes printing. In order to save costs, many printer ink cartridges have a structure that allows ink to be refilled repeatedly, which can reduce the number of times ink cartridges are purchased and meet the needs of most people.

[0003] However, since the ink cartridge of this structure is not transparent, it is difficult to clearly and intuitively know the amount of ink inside the ink cartridge during use, especially when the ink color is too light. In addition, the connection between the cover and the base of the ink cartridge is not stable. After the cover and the base are connected, there is no fixed structure, and the cover is easy to fall off. Utility Model Content

[0004] In order to overcome the deficiencies of the existing technical solutions, the utility model provides a printer ink cartridge, which can effectively solve the technical problems that the ink remaining amount of the current ink cartridge is difficult to display and the ink cartridge cover is easy to fall off.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-6 As shown, the utility model provides a printer ink cartridge, which is mainly used for printer ink cartridges. Users can maintain printing by injecting a certain amount of ink into the ink cartridge. Its specific structure is mainly composed of a cover body 1 and a bottom box 2 with a top opening. The bottom box 2 can be filled with 4 different colors of ink and then printed through the nozzle 6 at the bottom, and the cover body 1 is used to seal the opening of the bottom box 2 filled with ink.

[0025] Four separated ink chambers 3 are provided in the bottom box 2, and the user can inject different colors of ink into different ink chambers 3 for printing. In order to prevent the ink in each ink chamber 3 from mixing, the position of the opening of the ink chamber 3 is aligned with the opening of the bottom box 2, and four transparent windows 5 are added on the side of the bottom box 2 to allow the user to directly view the inside of each ink chamber 3. The transparent windows 5 extend in the direction of the depth of the ink chamber 3, that is, they are distributed up and down. The user can know the amount of ink remaining inside through each transparent window 5 and whether it needs to be injected and filled. At the same time, the transparent window 5 adopts a transparent structure, which can avoid the situation where the ink color is too light and the ink amount cannot be displayed, making it more convenient to use.

[0026] The cover 1 is sealed and assembled at the opening of the bottom box 2, which seals the opening and protects the ink in the internal ink chamber 3. When the cover 1 is assembled at the opening of the bottom box 2, four sealing parts 9 extending into different ink chambers 3 are provided at the bottom, and the side of each sealing part 9 is tightly attached to the inner wall of the corresponding ink chamber 3 to form a seal. In order to better fix the cover 1 assembled on the surface of the bottom box 2, a raised clamping strip 10 is provided on the side of each sealing part 9, and correspondingly, a fixing groove 4 corresponding to the clamping and fixing clamping strip 10 is provided on the inner wall of the ink chamber 3. When the cover 1 is assembled, the clamping strip 10 slides into the corresponding fixing groove 4 and is fixed, thereby strengthening the connection between the two and improving the fixity after connection to prevent the cover 1 from falling off.

[0027] In addition, when the cover body 1 is assembled at the opening of the bottom box 2, an anti-mistake portion 8 is added at the connection position between the two, through which the user can quickly identify the direction of the cover body 1 and the connection alignment. The specific structure of the anti-mistake portion 8 mainly includes an anti-mistake groove 801 provided on the surface of the bottom box 2 and an anti-mistake block 802 provided at the bottom of the cover body 1 and inserted into the anti-mistake groove 801 to prevent random insertion.

[0028] When ink needs to be injected into each ink cavity 3 inside the bottom box 2, four ink injection ports 15 are provided on the surface of the cover body 1, which are respectively connected to different ink cavities 3. The user can inject ink of corresponding colors through the ink injection ports 15 and check the ink amount in real time through the through window 5. After the ink is injected, a sealing plug 16 is added to the ink injection port 15 to seal it.

[0029] It should be supplemented that the nozzle 6 for the ink cartridge printing is arranged at the bottom of the bottom box 2. During the printing process, the nozzle 6 performs inkjet printing under corresponding control. A raised portion 11 for installing the nozzle 6 is provided at the bottom of the bottom box 2, and a chip 7 for controlling the nozzle 6 is installed on the side of the bottom box 2. The nozzle 6 performs inkjet printing under the control of the chip 7. At the same time, an ink cartridge belt 12 is also connected between the chip 7 and the nozzle 6. The ink cartridge belt 12 is a soft structure that can be bent. The ink cartridge belt 12 is bonded to the surface of the raised portion 11 and the side of the bottom box 2 connected to the chip 7. Through the ink cartridge belt 12, signals can be transmitted between the chip 7 and the nozzle 6 to complete printing.

[0030] When the ink cartridge needs to transfer ink to the nozzle 6, a conductive ink flow channel 14 is provided between the nozzle 6 and each ink chamber 3, and the ink in different ink chambers 3 can flow to the nozzle 6 along the corresponding ink flow channel 14. At this time, the ink flow channel 14 is at the bottom of the ink chamber 3, and a convex block 13 protruding upward is provided at the opening of the ink flow channel, through which the purified ink can be obtained, so as to prevent impurities in the ink from reaching the nozzle 6 along the ink flow channel 14 and causing damage to the nozzle 6, thereby improving the safety of use.

[0031] Compared with the traditional technology, the present technical solution adds a transparent window 5 for visually observing each ink cavity 3 on the side of the base box 2, which allows the user to visually observe the remaining amount of each color ink in the ink cartridge in real time to determine whether ink needs to be added, and also avoids the situation where the ink color is too light to be displayed. At the same time, when the cover body 1 and the base box 2 are closed, an anti-mock portion 8 is set between the two to facilitate alignment. The sealing portion 9 at the bottom of the cover body 1 is fixed in the fixing groove 4 in the ink cavity 3 by a clamping strip 10 to enhance firmness and prevent the cover body 1 from falling off.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
