Abstract

The invention relates to a writing instrument which comprises a common-used writing pen point which is used for coating writing ink on a writing medium, a first ink storage cavity and a second ink storage cavity which are provided with ink outlets, are arranged up and down and can be rotatablely connected with each other; wherein, the first ink storage cavity and the second ink storage cavity are used for providing writing ink and a splicing sleeve for the pen point; a splicing sleeve is used for connecting the pen point and the first ink storage cavity. The invention also comprises a joint washer which is arranged between the first ink storage cavity and the second ink storage cavity. The invention is characterized in that the top of the first ink storage cavity is penetrated with a first ink conducting core; at least part of the end of the first ink conducting core exposes out of the top of the first ink storage cavity and the other end extends into and is connected with the writing pen point, thereby being capable of adding ink storage amount and also preventing and avoiding leaking phenomenon effectively. The invention has the advantages of simple and reasonable structure, low cost, which is suitable for batch production.

Description

Writing implement

Technical field

The present invention relates to a kind of writing implement, particularly as the writing implement of color pen, felt material stylus, fibre-tip pen, ball pen, pen and other types.

Background technology

Writing implement on the existing market, complex forms is changeable, great variety of goods, but all have following common shortcoming: 1, deposit write black liquid storage very little, thereby it is very high to irritate the frequency write black liquid from ink bottle, is pretty troublesome really, and nib is partly very dirty during can.2, because of this body structure of writing implement institute extremely, itself can bear when depositing the capacity of writing black liquid if surpass to writing implement filling, the very easy ink leak water of this pen then, so its anti-performance of leaking is just poor, so write the structure that the capacity of black liquid belongs to low capacity in the existing writing implement.3, especially popular a kind of disposable writing implement just be abandoned when also very new because of the structure that uses up fast of writing black liquid often, thereby the utilization rate of lump-sum is very low, causes the very big wasting of resources.

Also there are a lot of inventors existing writing implement being studied and improved at the problems referred to above, for example, a kind of marking tool of describing in the WO93/0596 patent application, also having at publication number is the writing implement of describing in the Chinese patent literature of CN1086173A.Disclose in these two parts of patent documentations and adopted large and small liquid storage cylinder to solve the black liquid storage problem very little of writing of depositing.Technical scheme mainly is to adopt diaphragm element to be divided into big ink storage chamber and less ink storage chamber ink storage chamber, and make opening of diaphragm element realize that the black liquid of writing of big ink storage chamber is fed in the less ink storage chamber by the flexible of tip of stylus, like this, though the liquid storage amount of this writing implement is increased, but when in writing process, needing writing black liquid and replenish to give less liquid storage cylinder from big liquid storage cylinder or afterwards, it writes the position that black liquid still can continue to flow to or be penetrated into marker nib, thereby cause the weeping when normally writing, one of its reason is that to be supplied to the liquid China ink of writing of less ink storage chamber be that lengthwise movement by a movable part makes valve open to big ink storage chamber, cause the inner pressure that produces of ink storage chamber, cause writing black liquid and constantly extrude and produce weeping.

Also there is the inventor making improvements at the existing defective of said structure, in the WO96/14998 patent application a kind of marking tool is disclosed for example, structure that it is basic and WO93/05966 patent and Chinese patent CN1086173A are similar, it mainly improves: little liquid storage cylinder is adopted the cyclic spring deformable piece, and purpose is above-mentioned water clock to be write black liquid when enlarging to suck back after nib moves forward in the process from nib by the compression of the cyclic spring deformable piece cavity on the service duct again.But this topology discovery moves forward in the process at nib, and the liquid that often flows to or be penetrated into nib too much can't in time suck back it, perhaps sometimes air is sucked back and writes liquid and almost seldom suck back.Moreover for adopting the common writing implement that has the tip of stylus of ball, because it is case type, permeating or be forced out the liquid that comes almost can't be sucked back, therefore, still exists weeping.

Summary of the invention

The objective of the invention is the defective that exists at above-mentioned present technology and a kind of liquid storage amount that can increase that proposes, can prevent and avoid simultaneously the writing implement of weeping again effectively.

Another object of the present invention is to be provided with first dexterously at the top of first ink storage chamber to draw black liquid core, make the black liquid of writing in second ink storage chamber very stably draw black liquid core and directly write black liquid to the tip of stylus supply from first, writing time is prolonged exponentially, this is simple and reasonable for structure, cost is low, economize on resources, be fit to produce in enormous quantities.

In order to realize the foregoing invention purpose, the present invention adopts following technical scheme: it comprises: tip of stylus commonly used, be used for to write black liquid and be coated in writing medium, first ink storage chamber and second ink storage chamber with liquid outlet, for being arranged above and below and being connected rotationally, be used to offer tip of stylus and write black liquid, adapter sleeve, be used to connect the tip of stylus and first ink storage chamber, seal washer, be arranged between first ink storage chamber and second ink storage chamber, it is characterized in that: the top of described first ink storage chamber is installed with first and draws black liquid core, first end that draws black liquid core has the top that partly is exposed at or exposes first ink storage chamber at least, the other end extends in the described tip of stylus, and is connected with described tip of stylus.

Described tip of stylus comprises that second draws black liquid core or comprise that second draws black liquid core and ball, and described second draws black liquid core and described first draws black liquid core and be connected or make one.

Being provided with the 3rd on the liquid outlet of described second ink storage chamber draws black part and/or is with black pearl.

The described second black liquid core is fiber liquid core or felt feed liquid core or the liquid core that has the diversion fiber.

Between the described seal washer and second ink storage chamber band is set.

The described second black liquid core outside is with overcoat.

Second ink storage chamber is provided with protective cover outward.

Be provided with in described first ink storage chamber and contain the liquid core.

The present invention adopts the top of first ink storage chamber to be installed with first mode of drawing black liquid core, first draw black liquid core and directly be supplied to tip of stylus by what the top was installed with second ink storage chamber of writing black liquid is housed, avoided writing black liquid and must being transformed in first ink storage chamber of second ink storage chamber in the prior art, to write black liquid by first ink storage chamber again and be supplied to tip of stylus, like this, the phenomenon of leakage very easily appears, the present invention has solved the black amount of depositing of writing implement effectively can reach raising exponentially, and cost and common writing implement are almost close, can prevent and avoid weeping effectively again simultaneously.
