Abstract
The utility model provides an ink cartridge equipped with a ventilating and waterproof film, and the ink cartridge comprises a housing. The outer surface of the housing is provided with a ventilating channel which is communicated with the external air. The ink cartridge also comprises a vent hole which is communicated with the ventilating channel and the housing, and the interior of the vent hole is provided with an ink storage cavity. An inner side, corresponding to the vent hole, of the housing is provided with the ventilating and waterproof film in a welding manner, wherein the film only allows the air to pass, and does not allow ink to pass. Therefore, the ink cartridge can adjust the internal air pressure of the ink storage cavity through the ventilating and waterproof film, so as to achieving the printing. The ink cartridge is simple in structure, is convenient to assemble, effectively prevents the ink in the ink storage cavity from flowing into the ventilating channel through the vent hole in case of polluting a user or causing the jamming of the ventilating channel, and is stable and reliable in performance.
Description
[technical field]
The utility model belongs to ink-cases of printers technical field, particularly a kind of print cartridge that is provided with permeable watertight film.
[background technology]
At present, on market, existing print cartridge more or less all can have ink to flow in airway in use procedure, easily pollutes user's hand and clothing, or easily causes airway to stop up for a long time and affect the performance of print cartridge, finally affects printing effect.
[utility model content]
In order to solve the above-mentioned technical problem existing in prior art, it is a kind of simple in structure that the utility model provides, easy to assembly, and effectively prevent that ink in ink storage chamber from flowing into airway by passage and polluting user or cause airway to stop up, print cartridge stable performance, be provided with reliably the print cartridge of permeable watertight film.
The technical scheme that the utility model solution prior art problem adopts is:
A print cartridge that is provided with permeable watertight film, includes shell, and the outer surface of described shell is provided with the airway being communicated with outside atmosphere, and is communicated with the passage of establishing ink storage chamber in airway and shell; Shell corresponding to described passage inner side be welded with only allow gas by and the permeable watertight film that do not allow ink pass through.
Further, the shell inner side that described passage is corresponding is provided with raised annular jig, and described passage is positioned at the annular of jig; Described permeable watertight film is welded on jig by ultrasonic wave mode.
Further, described permeable watertight film is to be manufactured and formed by ventilative water-proof material
Further, described permeable watertight film ink under the condition of 0.4atm vacuum can not pass through.
Further, described shell is mainly made up of the cover being bonded with each other and housing; Described airway and passage are all located on cover, and one-body molded; Described permeable watertight film is welded on the inner side of cover.
The beneficial effects of the utility model are as follows:
The utility model is that the air pressure inside of capable of regulating ink storage chamber is printed to realize by permeable watertight film, simple in structure, easy to assembly, and effectively prevent that ink in ink storage chamber from flowing into airway by passage and polluting user or cause airway to stop up, print cartridge stable performance, reliable.
[accompanying drawing explanation]
Fig. 1 is the package assembly schematic diagram of a kind of print cartridge embodiment that is provided with permeable watertight film described in the utility model;
Fig. 2 is the sectional structure schematic diagram of a kind of print cartridge embodiment that is provided with permeable watertight film described in the utility model;
Fig. 3 is the plan structure signal of a kind of print cartridge embodiment that is provided with permeable watertight film described in the utility model.
[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 to Figure 3:
A kind of print cartridge that is provided with permeable watertight film described in the utility model implementation column, includes shell 1, and the outer surface of described shell 1 is provided with the airway 13 being communicated with outside atmosphere, and is communicated with the passage 15 of establishing ink storage chamber 14 in airway 13 and shell 1; Shell 1 inner side of described passage 15 correspondences be welded with only allow gas by and the permeable watertight film 17 that do not allow ink pass through.Concrete structure can be: described shell 1 is mainly made up of the cover 11 being bonded with each other and housing 12; Described airway 13 and passage 15 are all located on cover 11, and one-body molded; Shell 1 inner side of described passage 15 correspondences is provided with raised annular jig 16, and described passage 15 is positioned at the annular of jig 16; Described permeable watertight film 17 is (as stepped the ventilative water-proof material of Bo macromolecular material company by ventilative water-proof material, this material is loose structure liquid to repulsive interaction, can allow gas freely pass through, and liquid comprise ink, in certain pressure reduction, can not penetrate into and pass through.) manufacture and form, its ink under the condition of 0.4atm vacuum can not pass through, and this permeable watertight film 17 is welded on jig 16 by ultrasonic wave mode.
Like this, print cartridge described in the utility model is that the air pressure inside of capable of regulating ink storage chamber 14 is printed to realize by permeable watertight film 17, simple in structure, easy to assembly, and effectively prevent that ink in ink storage chamber 14 from flowing into airway 13 by passage 15 and polluting user or cause airway 13 to stop up, print cartridge stable performance, reliable.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
