Description

A kind of ink method of liquid pens

The application is the applying date：2017-02-22, denomination of invention：Liquid pens, application number:201710096387.9 patent The divisional application of application.

Technical field

The present invention relates to a kind of liquid pens.

Background technology

Fig. 1 is existing liquid pens structure diagram, mainly including penholder, tail plug, blotting pen tip, sponge, ink storage cavity, Pen cap；The principle of this liquid pens is that the ink in ink storage chamber body is flowed into cavernous body, when the ink saturation of cavernous body infiltration When, the ink in ink storage chamber body is no longer flow into sponge, so as to keep cavernous body metastable to blotting pen tip ink supply, But the problem of existing one very big is exactly with the continuous reduction of ink in ink storage chamber body, hydraulic pressure reduction in top can cause to flow Enter the ink in cavernous body it is fewer and fewer there have been just begin to use when ink storage chamber body in ink it is more, liquid pens only need Using the power of very little, to spit ink just very much, but when ink is fewer and fewer in later stage ink storage chamber body, it is necessary to very big Strength can spue a certain amount of ink, thin so as to cause word early period in the thick later stage of writing, unless constantly adjustment is firmly Size.

Invention content

The technical problem to be solved in the present invention：It solves existing liquid pens and spits ink uneven caused early period and later stage writing The non-uniform problem of letter thickness.

In order to solve the above technical problems, the technical solution adopted by the present invention：Liquid pens, including penholder, tail plug, blotting pen Point, sponge and pen cap；Sponge is located in the lower cavity of penholder, and blotting pen tip one end is located in sponge, and the other end is located at penholder It is external；It is characterized in that,

The inside of the sponge forms a spheroidal cavity, and one end of the blotting pen tip is located at the ball In shape cavity, the other end is located at the outside of penholder；

If the volume of the spheroidal cavity is V；

Further include partition board, the first ink storage cavity, the second ink storage cavity and elastomeric cap；

The cavity on penholder top is separated into the first ink storage cavity and the second ink storage cavity by the partition board；

If the volume of the first ink storage cavity is V1, the volume of the second ink storage cavity is V2；

V1 is at least 10 times of V2；

V2 is at least 3 times of V；

On the partition board set a hole, hole lower position set elastomeric cap, a part for elastomeric cap with every It is fixedly connected between plate, the other parts of elastomeric cap are connectionless between partition board；

When negative pressure occurs in the second ink storage inside cavity, elastomeric cap is opened, and the ink in the first ink storage chamber body enters In second ink storage chamber body；

When the second ink storage inside cavity normal pressure presses situation, elastomeric cap automatically resets by the elasticity of itself by hole automatic sealing package It closes.

Wherein more preferred technical solution, elastomeric cap between partition board only there are one point with being fixedly connected.

Compared with prior art, the beneficial effects of the invention are as follows：

First, the word write when liquid pens of the invention are incipient or when ink runs low is all thick It is thin uniform；Second, it is firmly uniform in entire writing process, do not need to be firmly small at first, writing a period of time exerts oneself It needs to increase.

Specific embodiment

The present invention is described in detail below in conjunction with the accompanying drawings.

Embodiment：Liquid pens, including penholder, tail plug, blotting pen tip, sponge and pen cap；Sponge is located at the lower chamber of penholder In vivo, blotting pen tip one end is located in sponge, and the other end is located at outside penholder；The inside of the sponge forms a spheroidal Cavity, one end of the blotting pen tip are located in the spheroidal cavity, and the other end is located at the outside of penholder；It is if described The volume of spheroidal cavity is V；

V1 is 10 times of V2；V2 is 3 times of V；

One hole is set on the partition board, the lower position in hole sets elastomeric cap, elastomeric cap only there are one point It is fixedly connected between partition board, the other parts of elastomeric cap are connectionless between partition board；

When negative pressure occurs in the second ink storage inside cavity, elastomeric cap is opened, and the ink in the first ink storage chamber body enters In second ink storage chamber body；When the second ink storage inside cavity normal pressure press situation when, elastomeric cap by the elasticity of itself automatically reset by Hole self-closed.

Operation principle explanation of the present invention：First, it is filled with ink always in sponge inner circular spherical cavity, so as to protect The ink supply for demonstrate,proving blotting pen tip is stablized relatively, once there is negative pressure in spheroidal inside cavity, ink meeting in the second ink storage chamber body and When supply, and when there is negative pressure (refer to and belong to the prior art less than pressure under normal circumstances) in the second ink storage inside cavity, elasticity Lid can be opened immediately and supply ink by the first ink storage cavity, and then elastomeric cap automatically resets by natural resiliency on enclosed baffle Hole, so the pressure in whole process in the second ink storage chamber body is nearly constant, and the pressure in corresponding spheroidal cavity is opposite Constant, so during entirely writing, blotting pen tip is out of ink uniformly, so as to the word even thickness of writing.

The method of the ink of the present invention：Tail plug is opened, adds ink, adding the process of ink will slowly carry out, addition The variation of liquid level in the first ink storage chamber body is observed a little while, when finding that the liquid level in the first ink storage chamber body no longer changes, Ink can continuously be added until liquid level is close near the upper end of the first ink storage cavity.
