Description

The liquid ink marking pen

The utility model relates to pen, particularly a kind of marking pen or blank pen that pours into liquid ink.

Existing marking pen and blank pen all are to adopt long one fiber rolled core, suck liquid ink naturally, write till can not writing ink, but still residual 1/3 ink on the fiber rolled core, and the ink that is sucked all can not be write to the greatest extent, waste bigger.Also have, the main alcoholic ingredient that leans on wherein of ink volatilization of marking pen and blank pen, from links such as production, packing, storage, market sales, need through some months and even year, because the size of a part cooperates and the plastic deformation under different temperatures, cause alcoholic ingredient in the pen to volatilize naturally and can not write word, so after some is sold to the consumer, open pen and just can not use, its quality can not be guaranteed.

The purpose of this utility model provides a kind of improved liquid ink marking pen, and it can prolong the resting period, guarantees that an ink inside is unimpeded, writes smoothly and prolongs and write length.

A kind of liquid ink marking pen described in the utility model comprises penholder, pen item, rolled core, fiber nib and the cap for brush, and it also is included in valve and the valve mandril that is provided with in the penholder; Described valve comprises that one is provided with the valve body that passage, passage periphery are provided with fixed cover in the middle of it, and a valve plug; The front portion of described valve mandril is provided with convex shoulder, the bar head of valve mandril is provided with vertical hole, pocketed springs on the bar head, and the spring bottom is against on the convex shoulder, plug-in mounting valve plug in the vertical hole of bar head of valve mandril, the bar head of valve mandril inserts in the valve body center-aisle together with spring and valve plug; Described penholder is the cavity of a splendid attire liquid ink, elastic sealing cover is equipped with at the rear portion of penholder cavity, and the centre of seal cover is provided with projection, and valve mandril is packed into together with valve in the penholder cavity, and, constitute the ante-chamber and the back cavity of penholder cavity thus by the front portion that the fixed cover of valve body is sealed the penholder cavity; In the ante-chamber of described the penholder cavity of packing into, a pen interior installation rolled core, a head plug-in mounting fiber nib; The described cap for brush comprises preceding cap and back cap, and preceding cap sleeve is contained on the pen head, and back cap sleeve is contained on the intermediate projections of penholder cavity seal cover, and cap can be opened valve plug by valve mandril and squeeze into liquid ink to rolled core after pressing.

The utility model adopts valve-type directly to inject liquid ink, valve closing when normality, ink stores with the isolation of front end written portion and separates, when ink marks to be write is sent out light, press several backs down cap, promote valve mandril thus, make valve open, liquid ink through guiding gutter enter the penholder ante-chamber and be adsorbed on rolled core and the fiber nib on, this moment can continue to write, until liquid ink has all been write.Valve under normal conditions, liquid ink is preserved in totally enclosed environment, makes the utility model guarantee security and reliability in circulation.

Below in conjunction with accompanying drawing the utility model is elaborated.

Accompanying drawing is a kind of structural representation of liquid ink marking pen.
