Description

Writing brush head assembly and writing brush

Technical Field

The utility model belongs to the writing brush field, concretely relates to writing brush head subassembly and writing brush.

Background

The traditional writing brush consists of a pen holder made of bamboo or other materials and a writing brush head, and also consists of a pen holder made of bamboo or other materials, a writing brush hopper fixed at the lower end of the pen holder and a writing brush head, wherein the writing brush is required to be prepared with ink or an ink box inkstone in advance when writing, and the writing brush is inconvenient to use when going out to write.

In order to solve the technical problems, for example, the chinese invention patent application "automatic ink supply writing brush" with patent number ZL200910246427.9 (application publication number CN102069658A) includes a pen holder and a pen head, the pen holder has an ink containing cavity for containing ink, an ink valve is arranged between the ink containing cavity and the pen head, the ink valve includes a helical 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

The utility model aims to solve the first technical problem that to the current situation of above-mentioned prior art, provide a need not spring and ink feeding smooth and easy's writing brush head subassembly.

The second technical problem to be solved by the present invention is to provide a writing brush with the above writing brush head assembly.

The utility model provides a technical scheme that above-mentioned first technical problem adopted does: a writing brush head component comprises

The pen holder is tubular, and the first end of the pen holder is used for locally inserting the writing brush head into the pen holder;

the pen container is tubular, the first end of the pen container is arranged on the second end of the pen holder, and the second end of the pen container is used for installing the ink bag;

the method is characterized in that: an air channel communicated with the inner cavity of the pen bucket is formed in the inner peripheral wall of the pen holder.

Preferably, the air passage extends substantially along the center line of the pen holder, and the number of the air passages is at least two and is arranged at intervals along the circumferential direction. Therefore, the subsequent ink flows downwards more easily, the ink is more smoothly flowed, and the phenomenon of ink leakage caused by accumulation of local ink due to unsmooth ink discharging is prevented.

In order to prevent ink from flowing out through the gap between the pen holder and the inner peripheral wall of the pen holder, a sealing structure for preventing ink from flowing to the outside is arranged between the inner peripheral wall of the pen holder and the outer peripheral wall of the pen holder. Therefore, ink can only flow out through the writing brush head, and the subsequent writing brush can reliably move ink in the pen conveying state.

The sealing structure may be in various forms, and an annular convex portion may be formed on the outer peripheral wall of the pen holder or on the inner peripheral wall of the pen container, but preferably, the sealing structure is an annular convex portion provided on the outer peripheral wall of the pen holder and extending in the circumferential direction, and the pen holder forms a sealing connection with the inner peripheral wall of the pen container through the annular convex portion.

In order to facilitate the subsequent ink to wet the periphery of the writing brush head, so that the subsequent writing brush head can more smoothly discharge ink, the upper end of the pen holder is positioned in the pen bucket, the upper end of the pen holder is provided with a plurality of extension parts which are circumferentially arranged at intervals and all extend upwards, and an ink discharge channel communicated with the air discharge channel is formed between every two adjacent extension parts. So, on partly ink directly flowed to the intermediate position of writing brush head, the other part flowed to the periphery of writing brush head through walking the black passageway for ink flows to whole writing brush head, makes follow-up writing brush head ink discharging more smoothly.

Preferably, each ink channel corresponds to one air channel, and the air channels are arranged opposite to the corresponding ink channels. The air channels and the corresponding ink channels can also be arranged in a staggered mode.

In order to make ink flow into the ink flowing channel more easily, an annular flange extending along the circumferential direction is convexly arranged on the inner peripheral wall of the pen bucket, and a gap communicated with the ink flowing channel is reserved between the annular flange and the upper surface of the pen seat under the condition that the upper end of the pen seat is positioned in the pen bucket.

In order to limit the position of the pen holder and prevent the pen holder from moving upwards, a blocking shoulder is arranged on the outer peripheral wall of the lower end of the pen holder, and the lower end face of the pen bucket is abutted against the upper end face of the blocking shoulder in the state that the pen bucket is installed on the outer peripheral wall of the pen holder.

The utility model provides a technical scheme that above-mentioned second technical problem adopted does: a writing brush with the writing brush head component is characterized in that: the pen also comprises a pen holder and an ink bag, wherein the upper end of the ink bag is arranged on the pen holder, the lower end of the ink bag is arranged on the pen holder, and the ink bag can be communicated with the air channel.

Compared with the prior art, the utility model has the advantages of: the air channel is arranged on the pen seat of the writing brush head assembly, air flows in through the air channel when the writing brush head is in a pen conveying state, air pressure balance in the pen seat is maintained, ink in the subsequent ink bag smoothly flows downwards to flow into the writing brush head, and the phenomenon that ink leaks due to accumulation in the pen seat due to unsmooth ink flowing is prevented.
