Chinese writing brush with function of automatic ink supply

Abstract

The invention relates to a Chinese writing brush with a function of automatic ink supply. The Chinese writing brush comprises a hollow funnel, a Chinese writing brush head, an ink container and an inksupply mechanism. A cavity communicated with the Chinese writing brush head is formed between the Chinese writing brush head and the ink supply mechanism. The ink supply mechanism is provided with anink guide passage and an air guide passage, the ink guide passage and the air guide passage are independent mutually, the cavity is communicated with the ink container through the ink guide passage,the funnel is provided with an air inlet passage communicated with the air guide passage, and the air inlet passage is communicated with the ink container through the air guide passage. The Chinese writing brush has advantages that in a movement state, fibers on the Chinese writing brush head naturally suck ink in the cavity, the ink in the cavity is continuously brought to the Chinese writing brush head, and thus, a negative pressure is formed in the cavity, and air enters the ink container through the air inlet passage and the air guide passage to keep balance of the internal air pressure ofthe ink container; then, the ink in the ink container continuously flows into the cavity to supply ink to the Chinese writing brush head, failure in flowing of the ink in the ink container to the cavity is prevented, and ink outlet quantity can be controlled easily.

Description

technical field [0001] The invention relates to a writing brush, in particular to a writing brush capable of automatically supplying ink. Background technique [0002] The traditional writing brush is made of bamboo or other materials and the brush head, and there are also bamboo or other materials made of the pen holder and the pen holder and the pen head fixed at the lower end of the pen holder.

[0003] In order to solve this problem, as the Chinese utility model patent "automatic water outlet writing brush" whose patent number is 200820015282.2 (authorization announcement number is CN201244985Y), the water outlet writing brush includes a pen holder and a brush point, and a sealed pen holder barrel is established in the inner cavity of the pen holder. The pen barrel can contain ink, the pen cap is threadedly c...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned automatic water outlet writing brush solves the problem of carrying ink, but there are still the following deficiencies: 1) When writing, the bolt needs to be unscrewed, and the water discharge valve ring is rotated, so that the ink in the pen holder can soak the pen head through the water outlet hole, and after writing Finally, the water discharge valve ring must be rotated in time to close the water outlet hole, otherwise the ink will continuously seep from the water outlet hole to the nib, and even drip to the table to affect the hygienic environment, which is inconvenient to use; 2) When writing, the ink in the pen holder It is basically supplied to the nib at a constant speed, so the writer cannot freely adjust the ink supply speed according to the font size that changes at any time

Although the above-mentioned patent realizes the free adjustment of the ink supply speed according to the font size that changes at any time during writing, the ink is supplied to the brush through the change of the spring. During the ink supply process, there will be residual ink between the coils of the spring, which will cause the failure of the spring during long-term use, thereby affecting the use of the brush, that is, affecting Brush life
