Description

Writing brush

Technical Field

The utility model relates to a pen, concretely relates to writing brush.

Background

The traditional writing brush consists of a brush holder made of bamboo or other materials and a brush head, and also consists of a brush holder made of bamboo or other materials, a brush hopper fixed at the lower end of the brush holder and a brush head.

The current writing brush, like the automatic ink supply writing brush in the patent application of the invention of China, the patent application number of which is CN200910246427.9 (the application publication number of which is CN102069658A), discloses an automatic ink supply writing brush which comprises a pen holder and a pen point, wherein the pen holder is provided with an ink containing cavity for containing ink, an ink valve is arranged between the ink containing cavity and the pen point, the ink valve comprises a spiral extension spring, and an internal channel of the spring is communicated with the ink containing cavity; under the non-pen-carrying state, the adjacent ring bodies of the spring are mutually closely matched to form liquid sealing fit, and under the pen-carrying state, the spring is stretched to form a gap for supplying ink to the pen point between the adjacent ring bodies.

Although the above patent realizes the arbitrary adjustment of the ink supply speed according to the font size that changes at any time during writing, it has the following disadvantages: 1) the ink supply to the writing brush is realized through the change of spring to the ink, and when needs write, the ink needs nib atress upwards to oppress the spring, through the clearance between the adjacent circle body, realizes supplying ink to the writing brush, and at the black in-process that supplies ink, can remain there be chinese ink between the circle body of spring, in long-term use, can cause the inefficacy of spring, and it is not smooth and easy to lower the china ink. 2) When the writing brush is not used, the pen head and the ink are separated by the ring body of the spring, so that the pen head is slowly dried and hardened after the writing brush is not used, the reuse of the writing brush is influenced, and the service life of the writing brush is seriously influenced due to the repeated use; in addition, the penholder comprises an upper penholder and a lower penholder which are in threaded connection, after the ink in the upper penholder is used up, the upper penholder can be detached, and the ink is added into the lower penholder, but the ink accommodating quantity in the lower penholder is limited, and when the ink is added, ink leakage is easy to occur, the writing brush is dirtied, and in addition, the ink is inconvenient to add.

SUMMERY OF THE UTILITY MODEL
