CN2290470Y - Refill of directly liquid-feeding ball-point pen - Google Patents

Abstract

The utility model discloses a directly liquid-feeding ball-point pen core, which is composed of a pen head 1, a front-end ink guiding core 2, a front-end flow limiter 4, an ink storing roll 6, a rear-end ink guiding core 7, a rear-end flow limiter 8 and an ink storing chamber 9. The utility model is characterized in that one end of the front-end ink guiding core 2 is inserted into a cavity of the pen head, and the other end of the front-end ink guiding core 2 goes through a central hole of the front-end flow limiter 4 and inserted into the ink storing roll 6; one end of the rear-end ink guiding core 7 is inserted into the ink storing roll 6, and the other end of the rear-end ink guiding core 7 goes through a central hole of the rear-end flow limiter 8 and goes into the ink storing chamber 9; the ink storing roll 6 is clamped between the front and rear flow limiters. The utility model has the advantages of stable ink outgoing, smooth writing and long service life.

Description

Direct-liquid type mound pen core

The utility model relates to lettering pen, particularly a kind of mound pen core.

The general mound pen core of the domestic and international manufacturer production that present market is seen, no matter be metal tube or plastic tube, its internal structure all is to insert in the written chamber by one in a water guide core, in the Chu Mojuan that insertion is made with fiber, because the dischargeable capacity of Chu Mojuan is subjected to great restriction, ink reservoir volume is few, simultaneously because the pore position is near from the water guide core, evaporation of ink speed is fast, China ink loss height and water guide core micropore are easily stopped up by crystal when not using, the aqueous concentration of water guide core altered a great deal when nib made progress two states with nib downwards, particularly when the ink among the Chu Mojuan is depleted to a certain degree, nib is placed several hrs up, and this pen core just can not use.Therefore to exist Chu Mo few for the mound pen core of existing structure, and ink loss in depositing process is big, and utilization rate is low, and the service life of pen core is short, the defective that user's financial burden is heavy.

The purpose of this utility model provides a kind of identical with present international type on overall dimensions, and on internal structure novel mound pen core inequality, it is steady that it goes out China ink, long service life.

The purpose of this utility model is achieved in that this pen core is made up of nib, front end water guide core, attaching parts, front end current limiter, pen core body, Chu Mojuan, rear end water guide core, rear end current limiter, ink storage chamber, tail plug, lead water core one end inserts in the written chamber, the mesopore of current limiter inserted in the storage China ink volume before one end passed, back water guide core one end inserts in the storage China ink volume, the mesopore that one end passes the back current limiter enters the ink storage chamber immersion, in ink, store up black entrainment in the middle of former and later two current limiters.

Accompanying drawing 1 is a longitudinal profile schematic diagram of the present utility model.

Be described in detail below in conjunction with accompanying drawing:

Nib 1 is contained in the head end that links parts 3, adopt existing mound nib, 2 one in front end water guide core inserts in written 1 chamber, the mesopore that attaching parts 3 and front end current limiter 4 are passed in the other end inserts in the fiber Sponge of storage China ink volume 6, front end current limiter 4 and rear end current limiter 8 are contained in the front end and the middle part of pen core tube intracoelomic cavity respectively, clamp fiber sponge storage China ink volume 6 in the middle of the two, current limiter 4,8 all is the parts that have the wing baffle plate type of the water guide core mesopore that can penetrate the same size external diameter, back water guide core 7 front ends insert storage China ink volume 6 rear end certain depths, the mesopore that back current limiter 8 is passed in the rear end inserts ink storage chamber 9 certain depths, ink is contained in the ink storage chamber 9, tail plug 10 tight tail ends at pen core body 5, water-tight when reaching written making progress, air tight when nib is downward.When nib is write downwards, back water guide core sucks the ink that is stored in the ink storage chamber 9 in the storage China ink volume 6 by capillarity, be incorporated into the ball position of nib 1 again by lead water core 2, when nib 1 is not upwards used, because front and back water guide core 2,7 and the effect of storage China ink volume 6, can not form ink and come back to phenomenon in the ink storage chamber 9, stable maintenance the wettability of former and later two water guide cores, because former and later two current limiters 4,8, former and later two water guide cores 2, the acting in conjunction of 7 storage China ink volumes 6, the air pressure in the whole pen core and the air pressure at written ball portion and front end current limiter pore place are in poised state all the time, have improved the ink leak temperature difference effectively.

It is stable that the utility model goes out China ink, writes smoothly long service life.
