Description
The utility model relates to the stationery field, particularly a kind ofly exempts to inhale the formula pen.
As everyone knows, but existing pen is water absorption type, and its structure comprises pedestal, be fixed on a fore shell on the pedestal and a back cover, the intrinsic proposition of pedestal front end sleeve, and the proposition outsourcing is provided with a pin, the pedestal rear end is fixed with the rubber pocket of suction, is provided with a wireway that passes straight through to the proposition place in the rubber pocket.When pin water, air can enter in the rubber pocket by wireway, influences a pin water outlet in order to avoid produce negative pressure.Use the pen of this kind structure, will absorb water in the bottle of Heisui River when ink uses up in the rubber pocket, overcoat always is stained with Heisui River during suction, must look for paper to come wiping after the suction, in addition also usually handle make dirty; And bottled ink makes the ink retrogradation, the water outlet of an influence pin uncapping afterwards apt to deteriorate or losing moisture content; Moreover, last class hour of student, also usually be with the Heisui River bottle, very inconvenient.Ballpoint pen and disposable signature pen are arranged at present, though there is not the inconvenience of pen suction, ballpoint pen and signature pen can not substitute pen all the time fully, on the legal documents or some are more regular and need on long-time files of preserving all handy pen to write; In addition then, the pen fluent writing, a pin is flexible than ballpoint pen and signature pen, is more convenient for bringing into play each one individual character.But it is too outmoded that the major defect of pen is exactly a way of supplying water, incompatible modern fast pace paces.
The purpose of this utility model be a kind of replaceable pen core of design exempt to inhale the formula pen.
Task of the present utility model is finished like this: exempt to inhale the formula pen, comprise a fore shell and back cover that is fixed on the pedestal and the proposition that is fixed on a pedestal front end band pin, on a fore shell, be stamped the cap for brush, it is characterized in that the pedestal rear end is fixed with an aqueduct, be provided with a wireway in the aqueduct, the air inlet of wireway lower end is positioned on the axis of aqueduct, communicates with air guide channel on the proposition, insert in the pen core aqueduct upper end, and pen core is fixed on the pedestal.The ink that use is worked as in the pen core uses up, pen core can be screwed off, change a new pen core, it seals by the upper end of aqueduct and backs down new pen core on being fixed on pedestal, ink can down flow to a proposition and a pin junction along aqueduct, the need that supply a pin to write, and the return-air after the proposition water can enter in the pen core by the air guide channel on the proposition, wireway, in order to avoid produce negative pressure.
The utlity model has reasonable in design, it is easy and convenient to change pen core, and pen core is easy to carry, can keep the water content of ink again, unlikely retrogradation, and capacity is also big.
