Description

A kind of print cartridge for preventing ink from flowing back

Technical field

Printing consumables technical field is the utility model is related to, more particularly to a kind of print cartridge for preventing ink from flowing back.

Background technology

At present, print cartridge is one of the most frequently used consumptive material in printing consumables industry, and the print cartridge on existing market passes through in ink Complicated air supply passage and breather cheek valve is set to carry out enclosure interior pressure balance regulation, complicated, ink storage to realize in box Measure low, bubble is easily produced during printing, ink may be spilt from air inlet when transporting print cartridge so that print quality reduces.

Utility model content

In order to overcome the above-mentioned deficiencies of the prior art, it is high to provide a kind of ink reservoir volume for the utility model, is not easy to produce during printing The print cartridge of anger bubble.

Technical scheme is used by the utility model solves its technical problem：

A kind of print cartridge for preventing ink from flowing back, including the drain pan and cover fitted together, be provided with the drain pan according to Inlet chamber, spongocoel, the first ink storage chamber and the second ink storage chamber of secondary connection, the inlet chamber are connected by entering air circuit with spongocoel Logical, first ink storage chamber is connected by the ink feed loop for preventing ink from flowing back with the second ink storage chamber, the second ink storage chamber side Wall is provided with ink outlet port.

As the improvement of above-mentioned technical proposal, the ink feed loop includes being horizontally set on the ink feed pipeline of drain pan bottom, Described ink feed pipeline one end is connected with the first ink storage chamber, and the other end connects with the second ink storage chamber, and the ink feed pipeline is provided with extremely A few reverse flow baffle.

As the improvement of above-mentioned technical proposal, the reverse flow baffle is vertical with ink feed pipeline, is provided with two pieces.

As the improvement of above-mentioned technical proposal, it is described enter air circuit be arranged on drain pan top, it is described enter air circuit one end with Inlet chamber is connected, and the other end is connected with the first ink storage chamber, and the spongocoel is arranged in air inlet loop path.

As the improvement of above-mentioned technical proposal, the spongocoel sets two, and the sea for absorbing ink is provided with it Silk floss, the sponge block spongocoel.

As the improvement of above-mentioned technical proposal, the drain pan is sealed with cover by a diaphragm seal.

As the improvement of above-mentioned technical proposal, the inlet chamber be provided with the air inlet that communicates of the external world, the air inlet and Ink outlet port is sealed by a sealed membrane.

The beneficial effects of the utility model have：

This print cartridge can mitigate gas by setting quantity of ink in the inking chamber of ink feed loop second to be constantly in high-end trim The generation of bubble, print quality is improved, while the setting of the first ink storage chamber and the second ink storage chamber causes printable amount to improve.

Brief description of the drawings

Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：

Fig. 1 is the structural representation of the utility model embodiment；
