Embodiment 1 (see Fig. 1-Fig. 6):
After a new ink storehouse that is full of ink 6 was installed on the connector 5, ink storehouse 6 ink inside flowed out the ink lead-in groove 15 that is full of relaying core 4, were soaked by ink up to nib 2 and relaying core 4 coupling parts.Meanwhile, be stored in air in the fibre pipe 3 and import groove 12 by nib 2 and overflow gap and ink and be transported to ink storehouse 6, the negative pressure that produces in order to the minimizing of eliminating in the ink storehouse 6 because of ink.Ink utilizes the capillarity of written material to liquid ink by the joint face of nib 2 with relaying core 4, ink is delivered to nib 2, in order to write.
When ink storehouse 6 temperature raise, air expands in the ink storehouse 6, air pressure increases, ink excessive under this condition offers nib 2 by ink lead-in groove 15, this moment, not every ink can both be utilized by nib, and the part that excessive ink inserts fibre pipe 3 by overflow gap and nib 2 is released in the fibre pipe 3.
Along with writing of nib 2, when flowing to the ink shortage of written 2 writing ends, ink in relaying core 4 or the ink that is released in the fibre pipe 3 are sent to written writing end under written material capillarity.
Under this enforcement state, the porosity of nib is designed to 40 to 50 percent, and the porosity of fibre pipe is designed to 90 to 92 percent, and the capillarity of nib 2 is better than fibre pipe 3.Could realize that so written 2 inks can absorb the ink that stores when short from fibre pipe 3.
The longitudinal rib 17 of the band gradient that radially distributes because of penholder 1 inner periphery is near the extruding of nib place to fibre pipe, fibre pipe is increased in the capillarity at this position, thereby rest in the fibre pipe 3 ink the nib 2 with relaying core 4 junctions always be in coherent condition, and fully offer the nib 2.When the rising of ink storehouse 6 temperature, excessive ink also can't arrive nib 2, but is stored in the fibre pipe 3 by clearance C.What this had just prevented that excessive ink from becoming to drip flows down from nib 2.
When the temperature in the ink storehouse 6 reduces, air pressure also reduces in the ink storehouse 6, ink in the relaying core 4 ink lead-in grooves 15 is absorbed back ink storehouse 6 at this moment, the ink that accumulates in overflow clearance C and the fibre pipe 3 also can be back to by the ink lead-in groove 15 of relaying core 4 in the ink storehouse 6, while is along with the minimizing of ink, air in the fibre pipe 3 also can flow to ink storehouse 6, and the negative pressure in the ink storehouse 6 will be cancelled like this.
Because have the existence of very strong capillary relaying core 4, when being consumed, also can realize by ink the conversion of ink and air easily.Like this, even the environmental change around the pen, an amount of ink also can be provided in the nib 2.Evidence, longitudinal rib 17 gradients of anchoring fiber pipe 3 are 2 to spend to 5 degree and be advisable in the penholder.The overflow clearance C preferably is not more than 0.1 millimeter, can obtain satisfied more effect like this.
Embodiment 2 (seeing Fig. 7-Figure 10, not the same Fig. 1 of Biao Zhu piece number):
Among the embodiment 2, relaying core 4 does not have the overflow clearance C with the connecting portion of nib 2.Ink lead-in groove 15 by relaying core 4 cooperates realization ink and the conversion of air between ink storehouse 6 and fibre pipe 3 with written 2 taper concave surfaces.
The course of work is as follows: when ink storehouse 6 was connected on the connector 5, ink passed to nib 2 by ink lead-in groove 15 on the relaying core 4.Under the capillarity of written material to liquid ink, ink is passed to the writing end of nib 2, realizes writing.Ink is by the 2 used up whiles of nib, and ink storehouse 6 negative pressure occurs because of the consumption of ink, and at this moment air is just sucked from writing end by nib 2, flow in the ink storehouse 6 by ink lead-in groove 15 then, has realized the elimination of negative pressure in the ink storehouse 6.
When temperature in the ink storehouse 6 raises, when air pressure increases, when excessive ink can not be by written 2 full consumptions, will be unloaded to fibre pipe 3 by written 2 afterbodys and relaying core 4 junctions.Because of having the effect of the longitudinal rib 17 of gradient on penholder 1 inner periphery, fibre pipe 3 is stronger in the capillarity near written 2 ends simultaneously, and ink can be assembled herein.The consumption of the writing ink along with written 2, the ink that accumulates in the fibre pipe 3 can offer nib 2 again.
On the contrary, when ink storehouse 6 temperature reduced, negative pressure can occur thereupon in the ink storehouse 6.Because the existence of pressure reduction, the ink that stores in the relaying core 4 ink lead-in grooves 15 can be back to ink storehouse 6.The air that is stored in simultaneously in the fibre pipe 3 also can be along with follow-up, negative pressure in eliminating ink storehouse 6.
Therefore, in this structure, temperature raises no matter the time and still reduces in the ink storehouse 6, the phenomenon that excess ink offers nib 2 can not occur, and the ink of nib 2 also can shortage, and ink can offer nib always with being stabilized.
Implement 3 (see Figure 11, do not mark the same Fig. 1 of piece number):
Under this enforcement state, the nib end adopts the pearl header structure, is made up of written relaying core 10, nib 8, pearl seat 9, pearl 7 four part.Nib 8 is made by the pass material that fiber that contains resin or sintering resin-oatmeal form.Nib 8 front end and pearl 7 is connected, and tail end is connected with written relaying core 10.Pearl seat 9 couples together pearl 7 and nib 8.Nib relaying core 10 porositys will be higher than the porosity of nib 8 during design, are better than written relaying core 10 with the capillarity that guarantees nib 8, and the capillarity of written relaying core 10 also is better than relaying 4 cores simultaneously.
The course of work is as follows: ink passes to written relaying core 10 from ink storehouse 6 through relaying core 4 ink lead-in grooves 15.Because the capillarity from relaying core 4 to nib 8 strengthens gradually, ink can be finished the transmission from the relaying core to nib 8.At last, through rotation and the capillarity of pearl 7, ink is write on paper.Simultaneously along with the carrying out of writing, the minimizing of ink storehouse 6 ink inside, the air of respective amount will be added to ink storehouse 6, realizes continuous writing.
When the rising of ink storehouse 6 temperature, air pressure increases, and excessive ink will be discharged in the fibre pipe 3.Along with the continuation consumption of ink, fibre pipe 3 will offer nib 8 by written relaying core 10 at the ink of assembling near written 8 ends then.
When the temperature reduction, when air pressure reduced in the ink storehouse 6, the ink in the relaying core ink lead-in groove 15 can be back to ink storehouse 6, and the ink and the air that accumulate in the fibre pipe 3 also can be back to ink storehouse 6, finally eliminate negative pressure.
Embodiment 4 (see Figure 12, other piece numbers are identical with Fig. 1):
Under this state, the nib end is made up of nib 11 and written relaying core 10.To nib 11, capillarity strengthens gradually from relaying core 4 to written relaying core 10, in order to realize the transmission of ink from ink storehouse 6 to nib 11.
If excessive ink is derived, ink will be unloaded in the junction of written relaying core 10 and relaying core 4 in the fibre pipe 3, and ink also can be back to ink storehouse 6 by ink lead-in groove 15 if necessary, realizes giving written stable ink to supply with.
Other enforcement states:
Ink storehouse 6: ink storehouse can be and can not replace form.
The connected mode of relaying core 4 and nib or written relaying core: as long as can realize the transmission of ink, other types of attachment also can adopt.
Fibre pipe 3: as long as can realize the unloading of ink, can realize ink conglomerates near the nib end, the assembling mode of material and penholder also can change.
In a word, as long as can realize the transmission of ink from the ink storehouse to the nib, external environment can realize ink to the unloading of packing material and the control of required air when changing, and ink just can be an amount of offers nib, so just can guarantee that continuous writing can avoid dripping from nib of ink one-tenth droplet again.
