Description

Pen core and the writing implement it uses it

Technical field

The present invention relates to technical field of stationery, more particularly, to a kind of pen core.

Background technology

Pen core is the significant components of writing implement, generally there is refill for ball-point pen, Neutral ball-point for ball-point pen, mound pen core, Parker pen core etc. Pen core.When ink is used up in pen core, can direct refill, abandoned without whole branch pen, exempt waste.Due to above-mentioned listed each Kind pen core ink is dye ink, and meeting water will become colored.If using pigment ink, the volatilization of such ink is fast, quick-drying during writing, Handwriting preserves that year is remote, and meeting water will not spend, but use original pen core structure, that is, pen core ink pipe one end open, black Ink pellet surface fills lithium base oil in pipe, and pigment ink is readily volatilized, and sealing requirements are not achieved.And as marking pen, e-Pointer, white Plate pen uses pigment ink, good airproof performance, but when ink is used up, lump-sum can only just be thrown away, and cause greatly to waste.To solve Waste, disclosed in application publication number CN2910605Y it is a kind of can ink marking pen, point set and written end are disassembled, Then ink is filled into ink storage core easily to make hand dirty when realizing recycling, but ink needs ink bottle, and operating, no Health, it is therefore necessary to be improved.

Invention content

In view of the deficiency of the prior art, the object of the present invention is to provide a kind of pen cores, solve poor sealing, more Change cumbersome, unhygienic, it is short that writing preserves the time limit, and writing meets water the problem of blooming.

To achieve these goals, the technical solution adopted in the present invention is：

A kind of pen core including nib, connector, Mo Guan, ink storage core and ink, seals after further including, and rear envelope is arranged on black pipe tail portion Coordinate with the black seal of tube；Connector is matched with black pipe front end, and a stomata, the stomata and Mo Guanxiang are at least opened on connector It is logical.Aforementioned nib is metal-nylon nib or mound nib；Aforementioned ink storage core uses rolled core；Aforementioned ink is color type Water-based ink；Envelope is that thread fitting is either interference fitted with black seal of tube fit system after aforementioned；Aforementioned ink tube material is not Become rusty steel or copper.

In addition, the present invention provides a kind of writing implement, aforementioned pen core is accommodated in penholder.

With the above structure, the invention has the advantages that compared with the prior art,：It has good airproof performance, convenient It replaces, hygiene, handwriting quick-drying, meets water and do not bloom, it is remote to preserve year.

Specific embodiment

As described below is only presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention.

Embodiment and operation principle, as shown in Figure 1：

Including nib 2, connector 3, black pipe 4, ink storage core 5 and ink, 6 are sealed after further including for a kind of pen core, and rear envelope 6 is arranged on ink 4 tail portion of pipe seals with black pipe 4 and coordinates；3 one end of connector is matched with black pipe 4, is exposed on the connector 3 outside black pipe at least A stomata 31 is opened, this stomata 31 is connected with black pipe 4 by channel 32.When writing, air is by stomata 31, by channel 32 Into black pipe 4, ink is by air pressure in ink storage core 5 in black pipe 4, before ink flows to nib 2 from top to bottom by written 2 rear ends Writing is realized at end.In order to make handwriting quick-drying, chance water is not bloomed, such as the vital documents such as contract signature, shareholders' meeting signature, It is remote that year need to be preserved, ink is optimal using color type water-based ink in ink storage core 5 thus.Nib 2 can be metal-nylon Nib or mound nib.Metal-nylon nib is made of diversion core 22 and pen core seat 21, and during writing, ink passes through diversion core 22 Rear end flows to 22 front end of diversion core from top to bottom, is supported and write by pen core seat, more securely, is unlikely to rock.Diversion core 22 is adopted With fibrous material, such as nylon.Mound nib is by ball and ball seat body.Having protected prevents ink from volatilizing, after being set at black 4 rear portion of pipe Envelope 6, rear envelope 6 coordinate with the black sealing of pipe 4, can use thread fitting or interference fit.General pen core ink pipe 4 uses plastics material Matter, in order to improve the grade, black pipe uses the metal materials such as stainless steel, copper, aluminium.In order to prevent ink by nib volatilization or It makes hand or clothes during carrying dirty, pen core cap 1 is set before nib.

Fig. 2 is that the present invention provides a kind of writing implement, and penholder 7, pen tip 8, pen cap 9 and pen clip 10 form, penholder content Receive above-mentioned pen core.

Color type water-based ink can be commercially available in market, writing implement assembly method, operation principle and prior art phase Together, which is not described herein again.
