Abstract
The utility model relates to an air intake valve of an inkjet cartridge, which comprises a box body and a front cover; an inkjet port is formed on the box body and an ink storage cavity is arranged in the box body; an air inlet port and an ink outlet are formed at one end of the box body; the air inlet port adopts an air inlet pipe structure and a vent rod and a vent rod installation position are arranged in the air inlet pipe; the end of the vent rod extending into the box body is designed to be a cylindrical platform; a seal ring installation position and a seal ring are arranged at the end part of the air inlet pipe; a positioning block is arranged at the other end of the vent rod; a spring is arranged between the positioning block and an air inlet pipe installation position; a double annular convex rib is arranged on the outer circumference of the seal ring; and a groove is formed on the rod body of the vent rod at the end near the cylindrical platform. Compared with the prior art, the utility model adopts the seal ring provided with the double annular convex rib to seal, so that the sealing is tight and reliable; no diaphragm seal is arranged on the air inlet port and only seal membrane is arranged at the ink outlet; and the air intake valve has an improved structure and more convenient manufacturing and use.
Description
Technical field
The utility model relates to print apparatus, especially a kind of ink-jet box intake valve.
Background technology
At present, the existing print cartridge that is used for ink-jet printer generally comprises box body and is located at the interior ink storage chamber of box body, and box body is provided with ink filling port, and the box body end is provided with air admission hole and ink outlet port, and ink outlet port, air admission hole and ink filling port are communicated with ink storage chamber respectively.The box body air admission hole is typically provided with intake valve, in print cartridge packed and transported or the use, sometimes cause having ink from the valve port seepage because intake valve is poorly sealed, so, some print cartridge utilizes pad pasting to be sealed into pore after ink storage chamber is filled with ink, but like this when using print cartridge, need at first puncture the sealing pad pasting could normally use, and makes and uses all comparatively complicated.
The utility model content
At the deficiency of above existing ink-jet box intake valve, it is tight, reliable that the purpose of this utility model provides a kind of sealing, and ink-jet box intake valve is comparatively easily made and used all in structure optimization.
The purpose of this utility model is achieved by the following technical solution:
A kind of ink-jet box intake valve, comprise box body and the cover that is located at box body one end, box body is provided with ink filling port, be provided with ink storage chamber in the box body, the other end of box body is provided with air admission hole and ink outlet port, described air admission hole is made as air feeder structure, be provided with air admission hole in the air inlet pipe, be provided with vent rod and vent rod installation position in the air inlet pipe, the end that vent rod stretches in the box body is made as cylindrical bar, be provided with sealing ring between cylindrical bar and the air inlet pipe, the vent rod other end is provided with locating piece, is provided with spring between locating piece and the air inlet pipe installation position.
As optimal technical scheme of the present utility model, the air admission hole inwall of described air inlet pipe is provided with cross vent rod installation position.
As optimal technical scheme of the present utility model, the air admission hole end that described air inlet pipe stretches into an end in the box body is provided with the sealing ring installation position, and the excircle of described sealing ring is provided with the Crossed Circle convex tendon.
As optimal technical scheme of the present utility model, described vent rod is provided with groove near the body of rod of cylindrical bar one end.
As optimal technical scheme of the present utility model, described ink outlet port is provided with sealing and chews film, and sealing is chewed and is provided with cushion rubber in the film.
As optimal technical scheme of the present utility model, be provided with the sealing plug in the ink filling port of described box body.
The beneficial effects of the utility model are: with respect to prior art, the utility model employing has Crossed Circle convex tendon sealing ring and seals, and its sealing is tight, reliable, and air admission hole is not established diaphragm seal, only establishes to seal at ink outlet port and chews film; The utility model structure optimization, manufacturing and use are all comparatively convenient.
