The specific embodiment

As Figure 1-3, according to a preferred embodiment of the present utility model, blank pen 1 is made up of nib 2, water storage core 3, valving 4, penholder 5 and tail plug 6 etc.Ink storage also can leave in the ink cartridge of independent setting in penholder 5.Nib 2 leading section 2a be spherical, is convenient to write and is out of shape when backing down valve little; Connecting portion 2b and pars intermedia 2c are cylinder, and wherein the diameter of connecting portion 2b is identical with the diameter of leading section 2a, and the diameter of pars intermedia 2c is less than the diameter of leading section 2a, and the little purpose of pars intermedia mill is to be convenient to blotting; Rearward end 2d is used for and the spool tight fit.Water storage core 3 can be made by fiber.Water storage core 3 and valving 4 are fixed in the penholder 5, an end of water storage core 3 and valving 4 adjacency, the other end and written 2 adjacency.

Shown in Fig. 4-7, valving 4 comprises valve gap 41, spool 42, spring 43 and valve body 44.Valve body 44 is fixed on the inwall of penholder 5, and the inboard close-fitting sealing of the outside of valve body 44 and penholder 5 is to prevent ink leakage.One end of valve gap 41 is fixed on the inwall of penholder 5, and its other end stretches in the valve body 44.The interference sealing is formed in the outside 41b of valve gap 41 and the inboard of valve body 44.Spool 42 passes valve gap 41, stretches in the valve body 44.The medial end 41a of valve gap 41 contacts with the outboard end 42a of spool 42, forms a valve 45, and both contact surfaces are preferably the conical surface.In the space of spring 43 between spool 42 and valve body 44, spool 42 passes from spring 43, thus an end of spring 43 in abutting connection with or be fixed in spool 42, the other end in abutting connection with or be fixed in valve body 44.Water storage core 3 is in abutting connection with the valve gap 41 of valving 4, and circle segment spool 42.Nib 2 stretches in the water storage core 3, and in abutting connection with spool 42.

Be provided with passage 7 in the spool 42, be used for ink transport to nib 2.One end of passage 7 is provided with opening 71a, 71b, and opening 71a, 71b below is provided with two

aperture

72a, 72b, and these two

aperture

72a, 72b are relative with water storage core 3.Two opening 71a, 71b or two

aperture

72a, 72b preferably are provided with symmetrically.

As shown in Figure 7, when the medial end 41a of valve gap 41 separates with the outboard end 42a of spool 42, be that valve 45 is when opening, ink can pass through opening 71a, 71b admission passage 7, and then supply to nib 2, and unnecessary ink can enter water storage core 3 by

aperture

72a, 72b, and temporarily be stored in the there.

Before the use, under the effect of spring 43, the medial end 41a of valve gap 41 contacts with the outboard end 42a of spool 42, and valve 45 is in the state of closing, and does not at this moment have ink in nib 2 and the water storage core 3.Because valve closing, can ink leak thereby guarantee not, this is safe to storage and transport.

At first be to add China ink during use, the leading section 2a of nib 2 is withstood on the desktop, the rearward end 2d contact spool 42 of nib 2, promoting spool 42 moves backward, spool 42 compression springs 43, thus the outboard end 42a of the medial end 41a of valve gap 41 and spool 42 separates, and makes valve 45 open.Pressure in the ink storehouse increases, and causes ink to flow into from valve 45.Because the gap between the main part 42b of spool 42 and the inboard 41c of valve gap 41 is very little, is about 0.05mm, forces opening 71a, the 71b flow channel 7 of ink from spool, and supply to nib 2.Unnecessary ink can flow in the water storage core 3 from aperture 72a, the 72b of passage, and temporarily is stored in the there.The user can press nib, presses China ink continuously, can fill up ink in the nib 2 after about one minute, and also store a certain amount of ink in the water storage core 3, at this moment can start writing and write.Under the active force of spring 43, spool 42 moves to the origin-location, and contacts with valve gap 41, thus closing valve 45.

In writing process, because the spring force of spring 43 is greater than the power of writing, valve 45 is in closed condition always.But, owing to have certain ink in the water storage core 3, add the capillarity of nib 2, make nib to draw ink from water storage core 3, tens meters the length of writing is arranged approximately.If writing shoals in writing, can add China ink fast, it is several down that nib is withstood on the desktop top once more, and written rear portion contact spool moves spool backward, and the compression spring, make valve open, ink extrudes from valve, and the passage that enters spool flows into nib 2 fast, and flows into water storage core 3, make nib be full of ink again, satisfy and write needs.

The openend inside of penholder can be provided with many muscle 51, preferably is provided with 6 muscle symmetrically.Water storage core 3 and written 2 is fixed in the penholder 5 by muscle 51, can constantly replenish air like this, thus the smoothness that further assurance is write.

According to blank pen of the present utility model, because the black capacity of storage is big in the penholder, adopt valve mechanism again, the residual volume of ink is very little, water storage core is significantly smaller than general rolled core again, the utilization rate of ink is in (tradition have only 70% with the utilization rate of rolled core water storage) more than 90%, thus it write the twice that length is general blank pen.

Though the utility model discloses preferred embodiment as above; right its is not in order to limit the utility model; anyly have the knack of this skill person; in not breaking away from spirit and scope of the present utility model; when doing various changes and retouching, therefore protection domain of the present utility model should be as the criterion with the claim scope of applying for a patent.
