Description

Printer ink box structure and printer

Technical Field

The utility model relates to the technical field of printers, in particular to an ink box structure for a printer and the printer.

Background

Inkjet printers are common printing devices. Most of the existing inkjet printers use ink cartridges detachably mounted in the inkjet printers to supply ink for printing, and during printing, the ink loaded in the ink cartridges is ejected onto paper as a printing medium to form desired patterns and characters.

The existing part of ink box is provided with a shell, the shell encloses a cavity, and an ink cavity and a sponge cavity are arranged in the cavity. The ink chamber is filled with ink, and the sponge chamber is usually filled with porous materials such as sponge. The traditional printer adopts black ink box and the colored ink box of three-colour more, and it needs to adopt black and colored printing shower nozzle, because this kind of ink box structure relates to parts such as black, colored printing shower nozzle more, and overall cost is higher, and production process is more, and it is unusual more easily, like the structure of conventional ink box, because the restriction of ink channel structure, the unable integrated into one piece of mould, so need have the side cap to guarantee overall structure's leakproofness, this just has increased side cap material and side cap ultrasonic welding technology, the cost increases.

Therefore, the structure of the ink cartridge for the conventional printer needs to be further improved.

Disclosure of Invention

The first technical problem to be solved by the utility model is to provide an ink box structure for a printer, which has a simple structure and can effectively simplify the processing and assembly procedures.

The second technical problem to be solved by the utility model is to provide a printer applying the ink box structure aiming at the current state of the art.

The utility model solves the first technical problem by adopting the technical scheme that: the ink box structure for the printer comprises an ink box main body, wherein an ink storage cavity is formed in the ink box main body, the ink storage cavity of the ink box main body comprises at least four independent sub-cavities which are respectively used for containing ink with different colors, the bottom of each sub-cavity is provided with an ink outlet for the ink in the sub-cavity to flow out, the ink outlets of each sub-cavity are adjacently arranged, and the ink outlets of the sub-cavities are arranged in a concentrated manner at the position of an area on the ink box main body for installing a printing nozzle.

In order to share the same printing spray head, a plurality of strip-shaped ink channels which are arranged side by side are arranged on the ink box main body at the position of the area for installing the printing spray head, and each strip-shaped ink channel corresponds to each ink outlet of each sub-chamber one by one and is communicated with each other respectively.

In order to meet the color printing requirement, the four sub-chambers are arranged in a shape of a Chinese character 'tian'.

The ink box with the Chinese character 'tian' shape structure has the integral deformation resistance superior to that of the traditional ink box structure with multiple cavities arranged side by side, obviously improves the dimensional accuracy of the position of the welding line, improves the welding effect and avoids the problem of color mixing of the ink box.

In order to form a plurality of sub-chambers, a partition plate is provided in the ink cartridge body, and divides the interior space of the ink cartridge body into the sub-chambers.

For reasonable space structure arrangement, the ink outlets of the sub-chambers are concentrated at the positions of the mutually-jointed areas of the four sub-chambers of the ink box main body.

In order to facilitate processing and ensure the integral strength of the ink box structure, the partition plate and the ink box main body are integrated.

The ink box structure of integrated design further reduces part number, has saved the required side cap of transmission ink box structure, does not also need the side cap ultrasonic welding technology simultaneously, reduces the process, the cost is reduced.

As an improvement, the bottom wall of each sub-chamber is provided with an ink outlet channel which extends from top to bottom and has a gradually-reduced caliber, and the bottom port of the ink outlet channel of each sub-chamber is the ink outlet.

In order to install the printing nozzle, the bottom of the ink box main body is provided with a caulking groove for the printing nozzle to be embedded therein, and each strip-shaped ink channel is correspondingly arranged at the position of the top wall of the caulking groove.

The utility model solves the second technical problem by adopting the technical proposal that: the printer comprises a printer body and an ink box arranged on the printer body, wherein the ink box adopts the ink box structure for the printer.

Compared with the prior art, the utility model has the advantages that: the ink box structure combines the traditional split type black ink box and the color ink box into the ink box structure with a plurality of split cavities, can realize the color printing purpose after being matched with the four-in-one printing spray head, and reduces the number of parts, the production process, the cost and the operation steps. The ink box structure can adopt an integral piece manufactured by a die integral forming process, the number of parts is further reduced, a side cover required by unlocking a traditional ink box is omitted, meanwhile, a side cover ultrasonic welding process is not required, the processing procedures are further reduced, and the cost is reduced.
