Abstract

The invention relates to liquid pen with large capacity. The liquid pen is capable of automatically supplying the ink and is smooth to write. The liquid pen is formed by sequentially connecting a pen cap, a pen point, compression sponge, an exchange hole, an ink storage chamber and a tail plug. The liquid pen is simple in structure.

Description

Liquid pens

Art

The present invention relates to a kind of liquid pens, liquid pens has big end pen, fibre-tip pen, improves its structure, makes liquid pens store more inks, and automatically supplying ink, use smoothness, do not overflow.

Background technology

At present, known liquid pens structure is by the cap for brush, and nib, sponge core, the shaft of a writing brush, tail plug forms.It is little that sponge core stores ink, a little pressure type, and ink reservoir volume is large, but hand is pressed, and uses inconvenience.

Summary of the invention

In order to overcome existing liquid pens ink storage off-capacity, or have capacity again can not the deficiency of automatically supplying ink, improve its structure, both ink reservoir volume be large, automatically supplying ink again.

The technical scheme that technical solution problem of the present invention adopts is: the length of the shaft of a writing brush about 2/3rds is used as ink storing chamber, and the length pad compressed sponge of 1/3rd, ink storing chamber is airtight, and an aperture is communicated with compressed sponge.Principle is, ink flows into sponge by ink storing chamber through aperture, and when sponge is saturated, under atmospheric pressure effect, the ink of ink storing chamber no longer flows into sponge.

Compressed sponge <1>: the difference of compressed sponge and not compressed sponge, both same saturation states, compressed sponge ratio not compressed sponge, in unit volume, ink contained by compressed sponge will lack.If what the shaft of a writing brush was filled is not compressed sponge, liquid pens, through keeping flat a period of time, re-uses, and nib ink supply can be caused too many, even can overflow.Compressed sponge also can replace with function same material.

Subtract stream pipe <2>: when the shaft of a writing brush of liquid pens is thicker, design one and subtract stream pipe, its dimensions length as far as possible length a bit, subtracts stream tube section and amasss a little bit smaller, can convection current between slow down air and ink, do not allow air be easy to enter ink storing chamber.

Exchange hole <8>: the size in hole is suitable, large, and between air and ink, convection current is large, nib ink supply is too many, Kong little Liao, and liquid pens uses continuously, there will be not smooth phenomenon, compressed sponge and subtract this being designed with of stream pipe and be beneficial to exchange hole and open larger.

Funnel <3>: hopper design is tapered, exchange hole is lowest part in ink storing chamber, and

Among exchange hole Embedded compression sponge, benefit is, ink uses completely, also have liquid pens to lie horizontally for a long time, under ink storing chamber's negative pressure, the contained ink above of compressed sponge sinks, form a small amount of air above, such profile design, can prevent air from entering ink storing chamber from penholder limit through exchange hole, ink overflow when prevention liquid pens re-uses.But effect is not very large like this, opens prevention effect.

Accompanying drawing explanation

Fig. 1 is liquid pens structure decomposition map.

Fig. 2 is the structure chart of liquid pens first embodiment.

Fig. 3 is the structure chart of liquid pens second embodiment.

In the drawings 1, compressed sponge 2, subtracts stream pipe 3 funnel 4, penholder part 5, screw position 6, nib 7, pen head part 8, exchange hole 9, ink storing chamber 10, tail plug 11, the cap for brush

In FIG, pen head part <7> inserts penholder part <4>, tail plug <10> inserts penholder part <4>, tail plug <10> designs a little silk mouth, tighten the screws position <5>, the positive confinement of tail plug.

In fig. 2, liquid pens puts on cap for brush <11>, open tail plug <10>, ink, because nib has put on the cap for brush, during ink, air in compressed sponge <1> can not be discharged, ink can not arrive nib and overflow, so this liquid pens can at tail plug <10> place ink, penholder part <4> comprises compressed sponge <1> position and ink storing chamber position, both are overall, form penholder part <4>, tail plug place ink is convenient.

In figure 3, decrease stream pipe <2>, penholder itself is very thin, and thin penholder serves, and reduces convection current between air and ink.Method of operating is the same with Fig. 2.

Beneficial effect of the present invention: increase liquid pens inking capacity, full-automatic ink supply, structure is simple, fluent writing.

Claims

1. a liquid pens, by the cap for brush, nib, compressed sponge, penholder, funnel, exchange hole, ink storing chamber, tail plug is linked in sequence, and it is characterized in that: fill compressed sponge in penholder.

2. according to claim 1, it is characterized in that: indoor design subtracts stream pipe.

3. according to claim 1, it is characterized in that: indoor design conical hopper.

4. according to claim 1, it is characterized in that: compressed sponge position and the ink storing chamber position of penholder part are overall structures, tail piston part ink.

5. according to claim 1, it is characterized in that: tail plug design screw-socket.

6. a liquid pens, by the cap for brush, nib, compressed sponge, penholder, funnel, exchange hole, ink storing chamber, tail plug is linked in sequence, its technical characteristic is: the filler of liquid pens, and by blotting, reach capacity state, air is made to enter ink storing chamber, meanwhile, under atmospheric pressure effect, ink storing chamber stops to filler for ink.
