The lower end of the pen core is inserted in the pen bag, and the upper end passes through a trepanning on the pen body cover, is closely sleeved with the trepanning, and stretches out a pen head. The pen bag is a cylinder shape, the inner portion is provided with a water absorptive sponge core, and the outer side surface is wrapped with a plastic film or a water-proof paper film and a metal film. The writing pen has simple structure, can be reused, and can add the writing liquid in a pen which writes on black/white boards in a direct suction or an injection mode. The handwriting and the lines of writing are clear, powder is not produced, the teaching environment is purified, the service life is long, and the cost is low. The writing pen capable of directly sucking and injecting writing liquid is suitable for blackboard-writing.

Description

A kind ofly can directly suck and pour into the lettering pen of writing liquid

Technical field

The utility model relates to a kind of teaching aid, in particular for the pen of writing in the black/white writing on the blackboard.

Background technology

In classroom instruction and academic exchange process, people use blackboard to add the literal teaching and the exchange way of chalk all the time, in use produce a large amount of dust, and harm teachers and students and participant's physical and mental health is polluted teaching environment.Progress and science and technology development along with society, people have invented many lettering pens miscellaneous and have replaced traditional chalk gradually, for example: disposable lettering pen and running water lettering pen and replaceable pen core lettering pen or the like, also corresponding the generation is used for the blank that pastel is write simultaneously.But a lot of problems of its existence are: the great majority that existing black/white plate lettering pen uses are that oiliness is write liquid, and stifled easily pen is fluid not, write on that writing is difficult to wipe on the black/white plate; What have belongs to disposable products, can not reuse, and causes user's use cost to increase; The structure more complicated that has; The function that has is complete inadequately; It is pretty troublesome that liquid is write in the interpolation that has, and uses inconvenience or the like.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, and good reliability is with low cost, can repeat to make with easy to use a kind ofly can directly suck and pour into the lettering pen of writing liquid.

The technical scheme that the utility model adopted is:

A kind ofly can directly suck and pour into the lettering pen of writing liquid, it comprises cylinder type hollow handwriting, handwriting lid and pen core, it is characterized in that:

Also comprise a capsule that is located in the handwriting inner chamber;

The outside screw of inboard and described handwriting upper end, the lower end of described handwriting lid connects, and the upper end is provided with the pen core trepanning;

Insert in described the capsule lower end of described pen core, and the upper end is passed described handwriting and covered trepanning and the tight socket of trepanning, and stretches out nib.

Described capsule is cylindrical, and interior is water imbibition sponge core, and lateral surface is wrapped with plastic foil, or fluid-tight paper film, metal film.

Described pen core is made cylindrical by fiber, the lower end is taper, and the nib of upper end can be taper, semicircle, flat or flat-headed.

Above structure can directly suck and pour into the lettering pen of writing liquid, in use, the cap for brush is pulled up.The handwriting upper end is threaded with the lower end of handwriting lid, can put into a capsule inner chamber of handwriting after the handwriting lid is turned on, and the sponge core in a capsule pours into writes liquid; The rear end of pen core is inserted in the sponge core deeply, the last trepanning that the front end of pen core sees through the handwriting lid stretches out nib, the handwriting lid is tightened with handwriting, promptly can be used on the black/white plate, writing, write liquid because the effect of fiber capillary in the pen core, automatically the sponge wicking from a capsule is got and is write liquid and be transported to nib equably, makes it to write.Otherwise, the cap for brush can be enclosed within handwriting and cover, entangled handwriting lid and nib, be easy to carry or collect.When writing liquid and using up, can resemble and to write liquid above-mentioned and directly pour in the capsule, also can stretch into nib and write liquid and draw automatically, up to for this reason saturated.Simple in structure, convenience ease in use.Comprehensively have following having a few:

One, easy to use: can adopt straight suction or the mode of pouring into to add and write liquid, simple to operation, only need liquid is write in the nib insertion, the pen core cotton will be write liquid automatically and be sucked, until saturated; Or handwriting is covered turn-knob open, directly pour into and write liquid to a capsule.

Two, long service life, cost are low: the nib of lettering pen is made by fiber, and wearability is good.Worn and torn with of a specified duration, need not to buy new pen, only need push away and stretch out nib or change pen core, can continue to use, saved expense of instruction.

Three, multiple functional: lettering pen has dissimilar nibs, stroke weight, and font size can reach perfect condition according to user's request.

It is big four, to write the liquid capacity: the attached ability of sponge wicking in the capsule is big, once can give directly to pour into 10～15ml and write liquid, and straight line is write length above 2000 meters.

Five, compact conformation, good reliability: the sponge core in the capsule is wrapping with thin plastic foil or relevant impermeable layer around being, writes liquid can not leak outside, and pen core and nib thereof are made for fiber, and it is uniform and stable that liquid is write in conveying.

Six, simple in structure, with low cost, be beneficial to suitability for industrialized production, be suitable for extensive marketing.

Fig. 1 is a sectional structure schematic diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Shown in Figure 1, be sectional structure schematic diagram of the present utility model.In the drawings, handwriting 1, sponge core 2, plastic foil 3, pen core 4 and nib 8 thereof, handwriting lid 6, handwriting lid lower end 5, handwriting lid trepanning 7, the cap for brush 9.As we know from the figure, by plastic foil 3 sponge core 2 is wrapped up in pillared capsule and be placed in the inner chamber of cylinder type hollow handwriting 1, the outside, the upper end of handwriting 1 is connected with lower end 5 inside threads of handwriting lid 6; Insert in described the capsule sponge core 2 rear end of pen core 4, and handwriting lid trepanning 7 is passed in the upper end, and stretches out nib 8; The lower port of the cap for brush 9 just is enclosed within on the waist of described handwriting lid 6.Wherein, described capsule is cylindrical, and sponge core 2 water imbibitions in it are very strong, and sponge core 2 lateral surfaces are wrapped with plastic foil, or fluid-tight paper film, metal film etc.Described pen core 4 is identical with the pen core of existing water-based writing on the blackboard pen, is made cylindrically by fiber, and the lower end is taper, and the nib 8 of upper end can be taper, semicircle, flat or flat-headed.Sponge core 2 is drawn and write liquid can be pen, writing brush general water-base ink or prepared Chinese ink, and this ink or prepared Chinese ink can be passed on the nib 8 from sponge core 2 by the effect of pen core 4 fiber capillaries, and nib 8 is write becomes possibility.Capsule and pen core 4 are prior art, or the person skilled in art can make easily according to prior art.

The utility model is a kind of simple in structure, can reuse, and can adopt straight suction or the mode of pouring into to add and write the pen that liquid is write in the black/white writing on the blackboard.Writing of writing and svelteness, fluent writing, the thickness of stroke can realize that font size all can reach ideal effect by selecting pen core.Do not produce dust, be of value to teachers and students' physical and mental health, purify teaching environment, the protection teaching equipment.Its long service life, nib 8 wearing and tearing backs only need to change nib, can use repeatedly, and are with low cost.Save teaching fund, be suitable for marketing and use.
