Description

Extruding water injection type fountain pen

The utility model relates to a kind of stationery: extruding water injection type fountain pen.

Fountain pen is generally widely-used, the indispensable stationery a kind of commonly used of current social people.Although it is of a great variety for traditional fountain pen, outward appearance is different, but its internal structure particularly water sucting mode does not have too big difference basically, all adopt the rubber-like water storage capsule, utilize suction water to be sucked the mode of operation of capsule after taking to push capsule, relieving, this stylographic shortcoming is: capsule suction is limited, be filled water and need push repeatedly; Written position, suction back has ink, needs to clean with waste paper, rag etc., often makes to speckle with ink on hand or pollute file; Ink bottle cover of every unlatching will have air to enter in the bottle, causes the ink oxidation; When ink in the bottle the is low difficulty that absorbs water during to certain " water level ", cause ink to waste.

The purpose of this utility model be to provide a kind of can civilization suction, prevent from inkiness and need not to open ink bottle cover to cause air to enter making ink oxidation deterioration, ink utilize the extruding water injection type fountain pen of the high less wastage of degree.

The utility model is to realize like this.This kind fountain pen is formed by nib, handwriting, the pen cap, the cap for brush, water pipe, bead with by the rear-mounted installation that elastic rubber tube, tail plug, water filling stopple constitute, its structure, the assembling feature as follows: nib, the cap for brush and handwriting superstructure assembled relation are identical with common fountain pen, insert in the water pipe handwriting lower end, and periphery is tightened with the screw thread pen cap outer with being enclosed within water pipe; Be provided with a bead in the water pipe of handwriting center through hole below, the water pipe lower end is provided with the tail plug, and below, tail plug centre bore position is provided with the water filling stopple, and water injection hole holds bossy body to be set with elastic rubber tube outward beyond the Great Wall.The mode of operation that this fountain pen adds ink forms suction by the elastic capsule in traditional extruding handwriting and sucks ink in the ink bottle, becomes the water pipe injection ink of extruding rubber-like ink bottle in handwriting.When this running water need add ink, the tegillum of supporting with it ink bottle cover top is taken off, the pen cap that the fountain pen water pipe is outer is backed out, and the water pipe afterbody is aimed at the position protruding upward of ink bottle cover vertically downward and compresses; Then, the sidewall of extruded ink water bottle, the ink that is extruded in the bottle enters suction pipe wherein, then enter the mesopore of the water filling stopple of this fountain pen lower end, up and outflow side, and enters in the water pipe in the gap between portion's bossy body along sebific duct and water injection hole at the water injection hole elastic rubber tube on portion's bossy body beyond the Great Wall beyond the Great Wall to the ink extruded sleeve in aperture along water filling stopple mesopore.Along with ink constantly enters water pipe, liquid level constantly rises, and the bead that swims on the liquid level rises thereupon, until handwriting lower end horn mouth central through hole is blocked.At this moment, if the extruded ink water bottle can feel that back pressure increases again, show that ink fills with.After water filling finishes, tegillum covered on ink bottle cover get final product.When the extruding force withdrawn from ink bottle, the elastic rubber tube in the fountain pen shrinks, be close to again water injection hole beyond the Great Wall on portion's bossy body with the sealing of side direction aperture, can prevent that an interior ink is back to ink bottle.

The utility model modern design, dependable performance uses this kind fountain pen can avoid inkiness, realizes that civilization adds water, can prevent from simultaneously to make ink rotten because of air enters ink bottle, and can make full use of ink, cuts the waste, and is suitable for extensive use.

Fig. 1 is the utility model general structure schematic diagram (among the figure, the cap for brush 3, the pen cap 4 do not draw).

Fig. 2 is water pipe and top thereof, rear-mounted installation structure enlarged diagram.

Fig. 3 is a special-purpose ink bottle structure schematic diagram.Among the figure, label " 11 " is a tegillum, and " 12 " are fluid sealant spare, and " 13 " are bottle cap, and " 14 " are bottle, and " 15 " are suction pipe.

Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
