Direct-fluid-supply writing

Technical field

The present invention relates to a kind of pen, more particularly to a kind of direct-fluid-supply writing.

Background technology

Direct-fluid-supply writing (including pen, ballpoint pen) is increasingly welcome by consumers in general now, presently commercially available direct-liquid type Pen is all using the sealing means of the outer nested pen of water receiver, and the mated condition of water receiver and pen item goes out when determining writing Ink whether it is smooth and whether leak.If water receiver is to coordinate tension with pen, cause writing out of ink not smooth even not out of ink Phenomenon；If the space existed between water receiver and pen is excessive, the space that ink can be between water receiver and pen is spilt.

Because water receiver and pen are all by ABS or PP injection moldings, when the machining accuracy error of part and production The operating error of master worker, therefore many direct-fluid-supply writings there is leak when dispatching from the factory or write the problem of water outlet has some setbacks； Simultaneously there is effect of expanding with heat and contract with cold in water receiver and pen, and some can write when dispatching from the factory, and water outlet is smooth and watertight direct-liquid type Pen, due to the change of local environment, the space between water receiver and pen changes, and occurs in that ink leakage or writing water outlet Have some setbacks phenomenon.

The content of the invention

The present invention is in view of the above-mentioned problems, propose a kind of direct-fluid-supply writing.

The technical scheme that the present invention takes is as follows：

A kind of direct-fluid-supply writing, including water receiver, pen, it is characterised in that also including sealing ring, be placed in the water receiver In item, pen item is circumscribed with the outside of an ink storehouse, water receiver and is provided with air inlet duct, and described air inlet duct one end is communicated with ink storehouse, separately One end is communicated with outside atmosphere, water receiver is enclosed on outside the sealing ring close to one end of ink storehouse, sealing ring outer wall is close to pen Inwall；Through hole is provided with water receiver, through hole one end is communicated with ink storehouse, another to be terminated with nib.

Due to adding a sealing ring between pen and water receiver so that pen is relative with the space between water receiver to be increased Plus, the passage that such outside atmosphere enters in pen is bigger, and outside atmosphere enters ink more easily by the air inlet duct on water receiver In sump, it can be ensured that water outlet is smooth during straight liquid pen writing；The inwall of sealing ring is close to water receiver simultaneously, and the outer wall of sealing ring is tight The inwall of pen is pasted, so when the ink in ink storehouse flow to sealing ring, can be stopped by sealing ring, a Xiang Yumi will not be passed through Space between seal is flow to outside pen.

Because this section of air inlet duct is the only way which must be passed that outside atmosphere enters in ink storehouse, if narrow, increase outside atmosphere is entered Enter the difficulty of ink storehouse；The space that a small amount of ink is penetrated between pen and water receiver by this section of air inlet duct is also had simultaneously, if It is wide, the space that substantial amounts of ink is penetrated between pen and water receiver in ink storehouse can be caused, so that there is ink leak phenomenon.

Optionally, in addition to air admission hole, the air admission hole is arranged on water receiver, enters air inlet duct as outside atmosphere Passage.

Optionally, the quantity of the air admission hole is no less than 2.

It is more smooth in pen that first air inlet number of perforations ensures that outside atmosphere enters no less than 2；Second when there is air admission hole to be blocked During plug, other air admission holes can still play a role, it is ensured that straight liquid pen still can normally be write.

Optionally, the periphery of the water receiver is provided with multiple annular grooves.

Under normal circumstances, the ink in ink storehouse by air inlet duct infiltrate it is few, if but straight liquid local environment Air pressure vary widely, the ink in ink storehouse can outflow, if without annular groove, ink can pass sequentially through air inlet duct and Air admission hole is leaked out, and the presence of annular groove to form the memory space of one on water receiver, and ink can be stored in In annular groove, it will not outside drain to outside straight liquid pen, the hand of user will not be made dirty.

Optionally, in addition to diversion conduit, the diversion conduit is arranged in through hole, and two ends are respectively communicated with nib and ink Storehouse.

Optionally, the connected mode of the ink storehouse and pen is to be detachably connected.

Because ink storehouse and pen are to be detachably connected, when ink is used up, ink can be added at any time or more renewed Ink storehouse.

Optionally, the nib is pen nib or ball pen nib or marker nib or brush writing skill.

The beneficial effects of the invention are as follows：

1st, writing water outlet is smooth, not ink leakage；

2nd, required precision during production and processing is significantly reduced；

3rd, through adding Mo Houke to be continuing with after ink is used up.
