Abstract
The invention relates to a printing machine air intake valve with an instant air vent closing function. An air inlet is formed in the top of a conventional ink cartridge of a printing machine, and after the conventional ink cartridge is assembled in the printing machine, a sealing film needs to be uncovered for use firstly; and when the ink cartridge is replaced, the air inlet cannot be timely closed, and residual ink always flows out to stain hands of a user or related equipment. The printing machine air intake valve with the instant air vent closing function comprises a main body, an air rod, a sealing ring and an elastic part, wherein the main body is cylindrical, two ends of the main body are respectively provided with an air inlet and an air outlet, a clapboard is arranged in the middle of the main body, an air vent is formed in the clapboard, the sealing ring is fixed on the air rod, a longitudinal air groove is formed in the air rod, a clamping block is arranged at the front end of the air rod, the air rod passes through the air vent, and the air vent can be blocked by the sealing ring due to the rebound of the elastic part. The air intake valve is simple in structure and convenient to use, has the advantage that the air inlet can be timely closed when an ink cartridge is replaced, and is widely applicable to various ink cartridges of printing machines.
Description
Technical field
The present invention relates to a kind of printing machine intake valve with the instant closing function of pore.
Background technology
Printing machine is carried out in the print job process, when ink is flowing out print cartridge, for keeping inside and outside air pressure balance, need have air to enter print cartridge simultaneously.Existing print cartridge top all has an air admission hole, the sealed membrane sealed of this air admission hole, and behind the printing machine of packing into, needing to throw off sealing film earlier could use.This print cartridge is when changing, and air admission hole can not be accomplished in time to close, and regular meeting has residual ink to flow out the user's that makes dirty hand or relevant device.The Chinese invention patent CN2818148Y of on 09 20th, 2006 bulletins discloses a kind of general novel print cartridge valve, and when printhead moved, vibration effect was opened, and closed when static, can control air inlet as required automatically.But this valve mechanism is too complicated, and each parts cooperates has relatively high expectations, and practicality and reliability have much room for improvement.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defective that how to overcome prior art, and a kind of printing machine intake valve with the instant closing function of pore is provided.
For solving the problems of the technologies described above, originally the printing machine intake valve that has the instant closing function of pore comprises main body, gas bar, sealing ring and elastic component, and described main body is cylindric, and two ends are respectively equipped with air inlet and gas outlet, the centre is provided with dividing plate, have pore on this dividing plate, described sealing ring is fixed on the gas bar, has air drain longitudinally on the described gas bar, and be provided with fixture block in front end, this gas bar passes pore, and under the bounce-back of elastic component, sealing ring can the shutoff pore.
So design, when print cartridge used, gas bar front end pressurized, sealing ring contracted after with the gas bar, are discharged into pore, INO; When needs replacing print cartridge took off print cartridge, the gas bar under the bounce-back of elastic component, was blocked air admission hole rapidly, INO together with sealing ring.
As optimization, described elastic component is sheathed on the gas bar outside for flexible back-moving spring, this flexible back-moving spring, and its front end connects on the fixture block, and its rear end is connected on the dividing plate.
So design, simple in structure, easy to use, air inlet is more smooth and easy.
As optimization, described gas outlet is provided with two-layer diaphragm seal.
So design, before the use, the diaphragm seal sealing, intake valve and print cartridge can not leak gas, more insurance.
As optimization, described gas rod rear end is provided with the spine over against described diaphragm seal.
So design behind the installation print cartridge, is contracted after the gas bar is squeezed, and its rear end can puncture diaphragm seal just.
The present invention is a kind of, and to have a printing machine intake valve of the instant closing function of pore simple in structure, easy to use, and when having the print cartridge of replacing, the advantage that air admission hole can in time be closed extensively is suitable for various printing machine print cartridges.
Description of drawings
Below in conjunction with accompanying drawing a kind of printing machine intake valve with the instant closing function of pore of the present invention is described further:
