Description

A kind of novel direct-liquid type structure pen

Technical field

The present invention relates to one have a water stop novel direct-liquid type structure pen.

Background technology

Present common direct-liquid type water receiver pen, front end dress water receiver, the rear end all is to adopt the shaft of a writing brush to irritate China ink, draw China ink to nib through the diversion core and write.Water receiver can prevent the leakage of shaft of a writing brush ink inside, and air channel can make the air pressure and the external world in the shaft of a writing brush be consistent, thereby reaches air pressure balance, smoothness during feasible writing.This advantage is that to irritate the China ink amount big, and it is longer to write length.Shortcoming is to change when various condition elements, particularly is heated and temperature when raising air expanded by heating in the shaft of a writing brush; Especially nib down, air is the ink upper strata in the shaft of a writing brush, ink will get into the water receiver interlayer through the return-air groove; Under the effect of every layer interlayer capillary principle, Chu Mo is in every section interlayer, because too much trickle groove structure is arranged; And it is consistent that every layer body structure surface hydrophily is difficult to reach, and this has just increased the air pressure that ink receives therein and the complexity and the unstability of capillary attraction, and quality is not easy controlled; Therefore often have the ink leak phenomenon to produce, this is a kind of defective of general water receiver structure pen.

Summary of the invention

The present invention be directed to the defective and the unstability of direct-liquid type water receiver pen.Increase the water stop device in shaft of a writing brush rear end, thereby improved a direct-liquid type water receiver ink leak phenomenon.This water stop adopts multisectional multilayer circular groove type principle, makes that being divided into multisectional multilayer with the ink in the front pen tube stores, and every layer all be independent ink storing chamber.When various environmental factors changed, the variate-value that reaches of the ink in every layer water stop was minimum at interval, be exactly nib down, air layer is all the time at orlop.The advantage of water stop is fully to intercept ink and air.

In order to realize the foregoing invention purpose, a kind of novel direct-liquid type structure pen disclosed by the invention comprises the shaft of a writing brush, nib and seals, and it is characterized in that said structure pen further comprises:

One water stop device is arranged between said nib and said the sealing, and said water stop device further comprises:

One water stop, its outside is cylindrical, inner core is a polygon, and some parallel and equally spaced water barriers vertically are set in axle center, said cylindrical surface upper edge;

One diversion core, cylindrical, be embedded in the inner core of said water stop.

Reasonable is that a diversion lamellar spacing is arranged between said diversion core and the said water stop.

Reasonable is that the inner core of said water stop is hexagon.

Water stop device direct-fluid-supply writing of the present invention has overcome the defective of water receiver pen, and through test high temperature, low temperature, negative pressure, each association such as simulate has all reached perfect condition.

Description of drawings

Below, with reference to accompanying drawing, for those skilled in the art that, from the detailed description to the inventive method, above-mentioned and other purposes of the present invention, feature and advantage will be obvious.

Fig. 1 is a cutaway view of the present invention;

Fig. 2 is the K-K cutaway view of Fig. 1;

Fig. 3 is the front view of water stop;

Fig. 4 (a) and Fig. 4 (b) and Fig. 4 (c) have provided A-A cutaway view and B-B cutaway view and the C of Fig. 3 respectively to sketch map.

The specific embodiment

See also shown in Figure 1, the present invention includes traditional water storage pen the shaft of a writing brush 1, be embedded the nib 2 of front end in the shaft of a writing brush 1, be arranged on the shaft of a writing brush 1 caudal part seal 4, in nib 2 with between sealing 4 a water stop device 3 is set.

The further structure of this water stop device 3 can combine Fig. 3 to understand; The water stop device 3 of Fig. 3 signal comprises that an outside is hexagonal water stop 30 and the some parallel water barrier that is vertically set on this cylindrical outer wall 33 compositions in cylindrical inboard is, also is provided with a cylindrical diversion core 31 in this water stop 30.In the structure that Fig. 2 provides, be the shaft of a writing brush 1 in the outside of said structure, ink 4 is between the shaft of a writing brush 1 and water stop 30; Because the outer wall of diversion core 31 is a cylindrical structural; And the inwall of water stop 30 is a hexgonal structure, so, a diversion lamellar spacing 300 is arranged between diversion core 31 and water stop 30.Because every section every layer water barrier 33 all is connected with diversion core 31 devices, write thereby from every layer of water stop, supply with nib endlessly.Communicate with the external world again in every layer of water barrier 33 in addition; When the ground floor providing ink produces negative pressure, replenish air through space, corner, the center section of water stop 30, make the ground floor of water stop 30 reach air pressure balance; The center of water stop 30 is designed to polygon, mainly is balance diversion and ventilation.The polygonal inscribed circle diameter of this pen design equates with diversion core 31 outside diameters, and the edge gap communicates with ambient atmosphere, and communicates with water stop 30 every layer hexagonal circumscribed circle places, thereby reaches every layer air pressure internal and external equilibrium.The gap design size of polygon corner is relevant with the viscosity of ink, surface tension, viscosity etc., adjust to neither ink leak, can communicate with ambient atmosphere again.See the explanation sketch map for details.

The external diameter of this water stop device 3 is consistent with the inwall footpath of the shaft of a writing brush 1.Thereby the ink that reaches in the shaft of a writing brush 1 is divided into multilayer and multistage obstruct.And all store up full ink in every layer, when writing, the China ink that draws of nib 2 begins from ground floor bottom, supplies with nibs through diversion core 31 endlessly to write, when the ground floor providing ink finishes.Begin to get into the second layer and will begin ink supply.And ground floor will become with the extraneous air that communicates and stops up.Air all the time from bottom to top.The external diameter of diversion core 31 links to each other with the polygon inscribed circle of water stop 30 in the water stop 30.There is an intersegmental crack to communicate in every layer with diversion core 31, as shown in Figure 2.

The ink of every each aspect will be supplied with diversion core 31 to nib 2 endlessly through the gap.When the ground floor ink supply reached negative pressure, every layer polygon edge gap 300 all had air to get into ground floor, thereby makes ink consumption reach balance, and inner and outer air pressure is consistent, fluent writing.Irritate quantity of ink and spend half of it when every layer, or during 1/3 ink, when high temperature air expanded, the air of lower end stopped up and can work as black layer of storage.Expanded by heating when completely adorning ink, the air in every layer the ink is few, because of no air, only can expand and overflow small volume of ink, and lower end water receiver 32 also can store up China ink in the interlayer.Every layer capillarity still exists.Can not cause the ink leak phenomenon.When temperature descended, the ink that overflows in the interlayer caused nib 2 by diversion core 31.Completion is reciprocal to last layer, has drawn to ending abundant writing ink.

The front provides the description to preferred embodiment, so that any technical staff in this area can use or utilize the present invention.Various modifications to these embodiment are conspicuous to those skilled in the art, can be applied to other embodiment to total principle described here and not use creativeness.Thereby, the embodiment shown in the present invention will be not limited to here, and the wide region of principle that should disclose and new feature according to meeting here.
