Abstract

The utility model provides a plunger-type tap water brush pen. The plunger-type tap water brush pen is characterized in that a pen holder is composed of a fixing pen holder and a movable pen holder. The fixing pen holder is made into a cylinder, and the movable pen holder is made into a plunger. The plunger is inserted in the cylinder, and can suck ink. A pen hair sleeve with an inner spline is connected to the lower end of the fixing pen holder, and pen hairs are inserted in the pen hair sleeve. The center of the upper part of the pen hairs is provided with an ink vessel. A pressure regulating valve is arranged on the movable pen holder. The problem that the plunger-type tap water brush pen temporarily dips ink when writing is solved, and the different requirements of the writing with large and small character fonts and different speeds to the flow rate of the ink are satisfied by changing pen grasp positions and regulating the pressure regulating valve. A plunger-type tap water device can be suitable for other water pens.

Description

Plunger-type fountain writing brush

The present invention relates to particularly writing brush of pen.

Writing brush is one of traditional writing brush, ink stick, ink slab and paper of China.Existing writing brush, the pen hair is inserted in the penholder lower end, does not have water absorber, soaks ink by the pen hair when writing temporarily, uses inconvenience, and ink marks is inhomogeneous.

The purpose of this invention is to provide a kind of plunger type fountain brush pen.Another object of the present invention provides different with font size of writing and speed, the writing brush that ink flowrate can change.

Invention is achieved in that penholder is by fixedly penholder and movable penholder are formed, fixedly penholder is made cylinder barrel, movable penholder is made plunger, plunger is inserted in the cylinder barrel and can moves up and down, fixedly the penholder lower end has connected a pen hair cover that has the internal spline of tapering, and the pen hair that top is inserted with ink conduit is contained in the pen hair cover.

Fixedly moving in the penholder by movable penholder, can suck ink or discharge cylinder barrel.When writing little, middle font, hand is taken fixedly penholder, and an ink that reaches pen mao by pen hair cover inner spline groove, ink conduit and a pen hair space can be coated on the paper equably; When writing big font, hand is taken movable penholder, and the flow of ink can size changes synchronously with writing firmly.

Further improvement of the present invention is to be provided with a pressure regulator valve on movable penholder, by the control of pressure regulator valve to ink flowrate, can satisfy the requirement of different writing speeds.

The pen of plunger type fountain brush pen mao available traditional various pen hairs are made, but the shaping of pen hair can not be coated with the gelatinous layer with the water proof trapping.Fixedly penholder, movable penholder, pen hair cover can adopt synthetic material manufacturings such as metal or plastics, but fixedly penholder is preferably made of metal material, can do barrel thinlyyer like this, it is poor to be beneficial to the diameter that dwindles fixedly penholder and movable penholder, and pressure regulator valve and ink conduit are preferably made with synthetic materials such as plastics.

The tapering of the pen hair cover internal spline of plunger type fountain brush pen is preferably between 1/5～1/10, and the degree of depth of keyway is preferably between 0.5～1 millimeter.The aperture, top of ink conduit is in 2 millimeter, and middle part to lower end preferably dwindles gradually with 1/5～1/10 tapering or being cross breaks.

Advantage of the present invention is: 1. make traditional writing brush realize automatic suction; 2. short ram travel can suck more ink; 3. it is easy and simple to handle to absorb water; 4. the writing of font is fit to vary in size; 5. plunger type running water device also is fit to other water-color paintbrush.

Accompanying drawing has been described one embodiment of the present of invention.Fig. 1 is the front view of plunger type fountain brush pen; Fig. 2 is the A-A amplification profile along Fig. 1; Fig. 3 is the B-B amplification profile along Fig. 1.

Describe the CONSTRUCTED SPECIFICATION and the working condition of the plunger type fountain brush pen of the present invention's proposition with reference to the accompanying drawings in detail.

Fixedly penholder (14) is made cylinder barrel, and there is positive stop key (12) upper end of cylinder barrel, and there is internal thread the lower end.Movable penholder (9) is made plunger, and keyway (7) is arranged on the face of cylinder, top, and two annular grooves (10) are arranged on the lower cylindrical face, and O type rubber seal～(11) are housed in the annular groove (10).Movable penholder (9) is inserted in fixedly has certain clearance in the penholder (14), cooperates with inner wall of cylinder by O type rubber seal (11) to reach sealing.On the top circumference of movable penholder (9) radial hole (4) is arranged, the axial direction of movable penholder (9) has a cylindrical hole (8), and a head has the pressure regulator valve (3) of decorative pattern (2) in upper end insertion activity penholder cylindrical hole (8).There are a radial hole (5) and axial aperture (6) to intersect in the cylinder of pressure regulator valve (3).Fixedly the lower end of penholder (14) is with the pen hair cover (16) that has been threaded, and two jointing end faces are lined with sealing gasket (17).The axial direction of pen hair cover (16) has a tapered splined hole (20), and pen hair (19) is housed in the splined hole (20), and the central upper portion of pen hair is inserted with ink conduit (15).

Fixedly there is a spring (13) to go up the movable penholder (9) in top in the cylinder barrel of penholder (14), presses down pen hair cover (16).

When writing brush need absorb water, earlier pressure regulator valve (3) is transferred to closed position (promptly two radial holes stagger), depress movable penholder (9) along arrow (1), the elastic force that plunger overcomes spring (13) moves down, discharge the portion of air in the cylinder barrel, all immerse pen hair (19) in the ink, pressure relief then, it is up that spring (13) is just pushing away plunger, meanwhile, ink is the spline (18) by pen hair cover also, and pen hair space and ink conduit (15) are inhaled in the cylinder barrel of fixing penholder (13).

When writing little, middle font, hand is held fixedly penholder (13); When writing than big font, but hand is held movable penholder (9).If will increase ink flow rate, can turn pressure regulator valve (3), make atmosphere enter cylinder barrel.
