Description

Device for supplying ink by extruding writing brush

Technical Field

The invention relates to an ink supply device of a writing brush for painting and calligraphy, in particular to an ink supply device for squeezing a writing brush.

Background

At present, three kinds of writing brushes for painting and calligraphy are available. One is a brush pen dipped with ink; the other is a so-called self-ink-supply writing brush; the third is a brush pen using extrusion ink supply. The former is in the author's painting and calligraphy in-process, directly dip in the chinese ink in the ink horn with the writing brush, and the writing brush nib carries out the painting and calligraphy operation after blotting fully, must stretch the nib again and dip in the chinese ink in the ink horn when the chinese ink that the nib adsorbed will be exhausted, just can the painting and calligraphy operation again. The ink dipping brush pen can only be a brush pen which can finish the painting and calligraphy work intermittently. Obviously, the brush pen is the most original brush pen and the most authentic brush pen, and the unique ink dipping mode of the brush pen makes the writing and painting works of the brush pen proper in shade and changes like the psychologically vivid verve. However, the intermittent ink-using mode is not preferred by the calligraphy and painting authors, and there is a long-standing need to improve the intermittent ink-using mode of the writing brush, so that many self-ink-supplying writing brushes with different shapes and colors appear in the calligraphy and painting operation. At present, the types of self-ink-supply writing brushes are various, but the foundation is that an ink bag for storing ink is added on a brush holder of the writing brush, so that continuous ink supply for painting and calligraphy operation becomes possible, and then a set of device for assisting the ink bag to convey the ink to a pen point is added, so that the effect of natural and smooth ink supply during painting and calligraphy operation is realized. These self-inking writing brushes still suffer from a number of undesirable technical drawbacks. Such as the following three points: firstly, the ink supply of the ink supply device realizes the continuous and uniform characteristic, but the painting and calligraphy works lose the appropriate shade and change into the psychological aesthetic feeling. And secondly, the ink is easy to lose water and is viscous when meeting air, the part of the ink close to the pen point is easy to glue, the ink is blocked to stop the painting and calligraphy often, and the post-treatment is very troublesome. In order to overcome the defect that the brush head of the writing brush is easy to be unsmooth in gluing, various ink dripping guide pipes adopted in the self-ink-supply writing brush are almost treated to be slightly thick, so the third technical defect is caused, namely the ink dripping phenomenon is difficult to inhibit, and even if a sealing plug capable of generating the vacuum effect in the ink bag is additionally arranged on the ink bag of the writing brush, the ink dripping phenomenon of the writing brush cannot be prevented in time due to the hysteresis property of the vacuum effect. Therefore, the self-ink-supply writing brush cannot be popularized, and a third type of writing brush for extruding ink supply is invented, so that the ink in the ink bag in the pen holder can be automatically extruded by the forefinger of a writer holding the writing brush, continuous ink supply can be achieved, and the technical effect that the ink is suitable for use in calligraphy and painting can be achieved. However, the brush pen with ink supplied by extrusion has some technical defects. Firstly, after the index finger of the writer holding the brush presses down the holder on the brush pen, the holder is not reset any more, the writer must move the index finger of the writer holding the brush pen down to obtain continuous ink supply, the gesture of the writer holding the brush pen becomes unnatural, and the writer can adapt to the brush pen only by long-time practice. The capacity of the ink bag for storing ink of the writing brush is too small. Because the effective height of the ink bag of the writing brush in the pen holder is limited by the distance which can be pressed down by the forefinger of the writer, and the distance is between 200 mm, the capacity of storing ink of the writing brush is too small.

Disclosure of Invention

In order to overcome the technical defects of various traditional writing brushes, the invention provides an extrusion ink supply device of a writing brush. The device for extruding and supplying ink is adopted by the writing brush, so that an author can meet the requirements of continuous ink supply for painting and calligraphy in the process of painting and calligraphy operation, the technical effect that ink is randomly used and the density is gradually increased can be achieved, and the worry of insufficient ink storage is avoided. Moreover, the writing brush with the extrusion ink supply device can not only continuously supply ink to the writing brush head under the condition that the writing brush is not stained by ink, but also maintain the normal ink using requirement under the condition that the writing brush head is thickened due to the water loss of ink.

The invention mainly comprises a penholder, an ink bag, a press plug, a press rod, an extrusion sheet, a pressure spring, a dropper and a pen point. An ink bag for storing ink is arranged in a pen holder of the writing brush. The lower end of the ink bag is provided with a hollow dropper which extends into the brush head of the writing brush. The upper end of the ink bag is provided with a plunger type press plug which extrudes ink downwards. The middle section of the press plug is provided with a sealing ring which is tightly attached to the wall of the inner cavity in the ink bag. The upper end of the press plug is provided with a column-shaped press rod which is connected into a whole, and the length of the press rod extends to be close to the top end of the writing brush when the ink in the ink bag is fully stored. The pressing rod is sleeved with an extrusion piece, one side of the extrusion piece is horizontally arranged in the inner cavity of the pen holder in a disc shape, and the diameter of an arc of the extrusion piece is smaller than that of the inner cavity of the pen holder of the writing brush. The center of the disk-shaped side of the extrusion sheet is provided with a hole with the diameter larger than that of the pressure rod, and the pressure rod is sleeved through the hole of the extrusion sheet. The other side of the extrusion piece is provided with a hand which extends out of the brush holder of the writing brush, and the forefinger of the writer when holding the writing brush slightly presses the hand. An upper positioning plate and a lower positioning plate are additionally arranged in the inner cavity of the brush holder, and the two positioning plates and the brush holder are connected into a whole. The diameter of the through hole at the center of the positioning plate is larger than the diameter of the pressure rod, and the pressure rod penetrates through the two holes. The lower positioning plate is arranged at the top end of the ink bag of the writing brush, and the press plug in the ink bag is also arranged below the lower positioning plate. The upper positioning plate is arranged at the middle section of the brush holder of the writing brush close to the lower side of the forefinger of the writer when the writer holds the writing brush, and the upper plane at one side of the circular sheet of the extrusion sheet is clung to the lower surface of the upper positioning plate. A pressure spring with up-down stretching tension is additionally arranged between the lower plane of one side of the extruded sheet in a disc shape and the upper plane of the lower positioning plate by taking the pressure lever as a center shaft. A sliding groove for the handle of the extrusion piece is formed downwards in an upper positioning plate arranged at the middle section of the brush holder, and the handle of the extrusion piece extends out of the brush holder from the groove.

By using the squeezing device for the writing brush, an author presses down the squeezing piece along the sliding groove on the writing brush holder by using the forefinger of the author to stretch out the holder of the writing brush when the author works in writing and painting. The squeezing sheet under the action of finger force is inclined towards the hand-joining direction under the retardation of the pressure spring below the squeezing sheet. The inclined extrusion sheet is sleeved on the plane of the circular hole of the pressure rod and loses the vertical state with the pressure rod, so that the downward extrusion acting force of the pressure rod is generated, and the pressing plug connected with the pressure rod is also extruded downwards along the wall of the ink sac cavity. When the ink in the ink bag is squeezed by the plug, the ink is forced to flow into the brush head of the writing brush along the hollow dropper at the lower end of the ink bag, so that full ink is provided for the writing brush for writing and painting. When an author stops exerting force to press a hand, the extrusion piece in the inner cavity of the pen holder is quickly returned and tightly attached to the lower surface of the upper positioning plate of the pen holder under the action of the pressure spring supported by the lower positioning plate of the pen holder to prepare for next ink extrusion, and meanwhile, the plane of the circular hole of the extrusion piece is also in a vertical state with the pressure rod, so that the pressure rod loses the downward extrusion force for driving the press plug, the expansion force of the upper sealing ring of the press plug plays a role, the press plug is stably stopped at the position, the ink in the ink bag completely loses the power for permeating into the drip tube, and the ink is immediately stopped to be conveyed to the pen point of the writing brush.

After the writing brush adopts the writing brush, the technical defects of various existing writing brushes are completely overcome. The calligraphy and painting method of the traditional writing brush can be perfectly inherited and scientifically developed, long-line and thick ink marks can be written when the ink is extruded and supplied, and calligraphy means of light ink and dry writing can be fully exerted after the extrusion is stopped, so that the technical effect of free and thick ink can be really achieved; the ink can be supplied automatically, ink is conveyed to the brush head of the writing brush completely independently by an author, when the brush head of the writing brush is swung, ink can be squeezed and taken immediately until all the ink in the ink bag is used up, and when the brush head is stopped and is not used, ink cannot seep into the brush head under the condition of negative pressure of the ink bag; thirdly, the problem that ink is not used smoothly due to the fact that the brush head is glued can be overcome, and the gluing of the brush head can be relieved by only slightly pressing ink and slightly scratching a plurality of pens on the piece of straw paper when the brush head is glued; fourthly, the situation that the ink drips and defiles the works due to out-of-control ink can be avoided, and the ink can not seep into the pen point any more when the pen is stopped; fifthly, the writing brush can be conveniently stored for a long time, because ink can not seep into the brush head any more when the writing brush is stopped, when the brush head is cleaned and stored for a long time, the brush head of the writing brush can still be ensured to be clean as before; the ink capacity in the ink sac in the pen holder can be improved to the maximum, the holder pressed by the forefinger can only move up and down repeatedly in a small range at the sliding groove position on the pen holder, and the press plug can reach the dropper position under the ink sac under the repeated extrusion of the holder, so that the effective height of the ink sac in the pen holder is improved to the maximum, the ink capacity of the ink sac is greatly increased, and the worry of insufficient ink storage is relieved.
