Abstract
The utility model provides an overflow proof device of an ink box. A one-way valve which is connected with an air passage and communicated with the atmosphere through the air passage is arranged in the utility model. The utility model can effectively prevent the overflow of ink because of the extrusion of the external force and avoid the environmental pollution. The utility model is simple in structure and lower in cost.
Description
Affiliated technical field
The utility model relates to printer, particularly ink-jet printer cartridge.
Background technology
In some no sponge ink-jet box, in order to guarantee not water clock of ink, increased by an end and be immersed in air duct in the ink, the other end and atmosphere communicate.
In actual use, find this structure because and atmosphere directly communicate, under the situation that the print cartridge outer wall is pushed by external force, along with the variation of inner space and pressure, ink can overflow from air duct, contaminated environment, and make troubles to the user.
The utility model content
For the problem of the spill and leakage ink that overcomes air duct, the utility model provides a kind of print cartridge anti-overflow device, and it can prevent the spill and leakage of ink effectively, avoids contaminated environment.
The utility model solve its technical problem technical scheme be: the inside of print cartridge is provided with check valve, and it and air duct be to connecting, and by air duct, links to each other with atmosphere.
The beneficial effects of the utility model are: can prevent effectively that ink from producing spill and leakage because of the external force extruding, avoids contaminated environment.And simple in structure, cost is low.
Description of drawings
Fig. 1 is the cutaway view that print cartridge of the present utility model has been installed.
Fig. 2 is the stereogram of anti-overflow check valve.
Fig. 3 is the cutaway view of anti-overflow check valve.
1 check valve among the figure, 2 valve ports, 3 air ducts, 4 inks, 5 ink box covers.
The specific embodiment
From Fig. 1, can see, one air duct 3 that is oval tubulose is arranged on ink box cover 5, in its bottom, and be the following positions of ink 4 liquid levels, as seen the check valve 1. that one anti-spill and leakage is installed, has a valve port 2 from Fig. 2 among Fig. 3 on the check valve 1, it is made under of at the pressure that is subjected to from inside to outside, can open.When the pressure that is subjected to from outside to inside, valve port 2 is closed.
The utility model is like this work: when ink 4 was printed machine and siphons away, its liquid level reduced, and internal pressure reduces, and atmospheric pressure is opened valve port 2, and additional air in certain amount.Push when the print cartridge outer wall is subjected to external force, and the print cartridge inner space is reduced, when pressure strengthened, valve port 2 was closed.And pressure is big more, closes tightly more.
Certainly, the profile of check valve 1 and structure can be not limited to shown in the figure.
Claims (3)
- The anti-overflow device of 1 print cartridge comprises lid, it is characterized in that, the inside of lid is provided with check valve, its direct and atmosphere connection.
- 2 print cartridge anti-overflow devices according to claim 1 is characterized in that being connected to air duct between check valve and the lid, and check valve is communicated with by air duct and atmosphere.
