Abstract

The present invention is applicable to that fountain pen suction washes the automatic sucking device for fountain pen of pen.It has changed conventional ink taking method.Its water sucting mode is that ink bottle cover is removed, and changes automatic sucking device for fountain pen, only the cap for brush is taken out during use, nib is inserted in the taper hole of automatic sucking device for fountain pen slide downwards, pen just can finish exhaust, water absorption course automatically.Its feature is that the ink that quick and convenient, the ink of suction does not pollute in finger and penholder, the ink bottle can absorb neatly.

Description

Automatic sucking device for fountain pen

The present invention is used for being spun on being used for the pen automatic sucking device for fountain pen of suction automatically on the ink bottleneck.

It gives people in work, study, thoughts communication since the Englishman has invented pen, and aspects such as information transmission bring great convenience, thereby is subjected to general welcome and application widely.Yet its water sucting mode is the ink bottle cover of outwarding winding always since pen comes out, and unplugs the cap for brush, turns on holding rod, pinches cachet, nib is stretched in the ink, after waiting to suck ink, screws bottle cap, penholder again, wipes clean written ink.Such water sucting mode seems cumbersome, and ink pollutes finger easily, and surplus in the bottle have small volume of ink to be difficult for blotting only.

The present invention improves greatly the traditional water sucting mode ground one of pen.Its water sucting mode is that ink bottle cover is removed, and changes automatic sucking device for fountain pen, during use the cap for brush is taken out, and nib is inserted in the taper hole of automatic sucking device for fountain pen to lower slider, and pen just can be finished the exhaust water absorption course automatically.Its advantage is that the ink that quick and convenient, ink does not pollute in finger and penholder, the ink bottle can be inhaled totally.Water aspirator also can play ink bottle cover sealing ink, prevent the effect of leaking and evaporating at ordinary times.To change clear water in the ink bottle, pen is stretched in the water aspirator to slide repeatedly up and down can reach the purpose of cleaning pen.Also can simplify pen structure decrease cost after generally using water aspirator.

Below in conjunction with accompanying drawing the principle of the invention and embodiment are awarded explanation.

Fig. 1 is the automatic sucking device for fountain pen down stroke figure that AB analyses and observe in Fig. 4.

Fig. 2 is the automatic sucking device for fountain pen up stroke figure that AB analyses and observe in Fig. 4.

Fig. 3 is the automatic sucking device for fountain pen up stroke figure that AC analyses and observe in Fig. 4.

Fig. 4 is the mansion view of automatic sucking device for fountain pen.

Fig. 5 is the EE cutaway view of automatic sucking device for fountain pen in Fig. 3.

Fig. 6 is the DD cutaway view of automatic sucking device for fountain pen in Fig. 1.

Automatic sucking device for fountain pen is to screw body (6) by screwing on the ink bottleneck, and bottleneck sealing ring (3) is contained in the suction nozzle (9) that screws on the body (6) with sliding fit.Be bonded in the suction lip (10) on the suction nozzle (9), be contained in and screw the sealing ring (8) of body upper end, be contained in the piston (4) that screws in the body (6), piston packing (5) in order to air-isolation, be contained in the back-up ring (2) on the suction nozzle (9), ink conduit (1) and spring (7) totally 10 parts are formed.

The part of dissecing of various seals is partly represented in blacking on the figure.Each seal can be made with soft material matter such as rubber, leather, spring spring steel wire coiling, the available plastics of all the other each parts, glass or lucite are made, and preferably adopt transparent material to make and can observe the mobility status of ink in automatic sucking device for fountain pen like this.The situation that pen and automatic sucking device for fountain pen coincide is represented in the double dot dash line of Fig. 1 top.Because the form of pen has multiple as bag point, reveal the needle tubing pen of point and drawing usefulness etc., thereby inhale lip (10) and can be made into various ways to adapt to the different forms of a stroke or a combination of strokes.The automatic sucking device for fountain pen that the double dot dash line of Fig. 1 bottom is represented has the mated condition of the spiral identical with ink bottle.

As shown in Figure 1 ink bottle cover is removed and change automatic sucking device for fountain pen, bottleneck sealing ring (3) screws body (6) and ink bottle with it and must not seal and leak.In use the cap for brush is extracted nib is inserted in the taper hole of suction nozzle (9), be bonded with at the awl mouth of suction nozzle (9) and inhale lip (10) the nib sealing is entered with isolated outside air.Spring (7) is compressed when sliding process under suction nozzle (9).Suction nozzle (9) has a micro-stroke as shown in Figure 2 with piston (4) when beginning to glide, this stroke disconnects breach (9d) and air chamber (h).Suction nozzle (9) continues to glide and will drive piston (4) downslide, and piston this moment (4) is convenient to screw body (6) and is formed an air chamber (h).Since continue trip slide effect lower chamber (h) down by suction pipe (9h) the identical effect of inhaling lip (10) and pen with its pen in the gas extraction.Sealing ring (8) enters air chamber (h) to reach the purpose of bleeding in the pen in order to cut off outside air.Piston packing (5) is in order to cut off air chamber (h) and interior two spaces of ink bottle.As shown in Figure 4 uniform 3 holes of the circle centre position five equilibrium of suction nozzle (9), on suck pipe (92) suction pipe (9b) to its tapering upper end open, under suck pipe (9c) to its lower ending opening, on suck and suck pipe (9c) under the pipe (9a) and routine in the lump opening is arranged as shown in Figure 3 at the middle part of suction nozzle, to suck pipe when locating up and down as shown in Figure 5 not connected when this and routine opening do not slide into throat (6a), this section stroke ink can not under suck pipe (9c) and enter and suck pipe (9a) gas and can only enter air chamber (h) by suction pipe (9b), this trip is an instroke.When descending the putting in place of suction nozzle (9), suck pipe (9a) up and down, (9c) two and routine opening aligns as shown in Figure 6 with throat (6b), and ink is suck pipe (9c) down and suck pipe (9a) on again by throat (6a) injections and supply an absorption from the taper hole outflow of suction nozzle (9) entering along the conduit (1) that inserts the ink bottle bottom under pressure of the inside of a bottle and the shaft of a writing brush suction.This process is a water absorption course.Treat the pen suction water after suction nozzle (9) under the effect of spring 7, upwards slide, begin that suction nozzle (9) only has a micro-stroke with piston (4) when up, breach this moment (9d) and air chamber (h) open circuit, if in pit (4a), at this moment flow back in the ink bottle by breach (9d) owing in the exhaust process pen, there is small volume of ink to be inhaled into air chamber (h) pool, suction nozzle (9) continues up, back-up ring (2) just drives piston (4) and returns formerly, and this process is a recuperation.Thereby automatic sucking device for fountain pen finishes once suction and carries out in three stages, and exhaust one suction one resets into next circulation and begins.
