Abstract

The invention discloses a writing tool. The writing tool includes pen tube, a sealing assembly and an output ink tube. The sealing assembly is arranged in the pen tube and one end of the sealing assembly is connected to a pen head. The ink pipe is arranged in the pen pipe and comprises a communication pipe and a plurality of through holes. The communication pipe is connected to the sealing assembly. The communication pipe comprises a main body, a channel formed inside the main body and an ink outlet end toward the pen; an ink outlet surface is formed on the ink outlet end of the communicationpipe; the support surface is in contact with the sealing assembly; each through hole is formed on the ink outlet end of the communication pipe and is arranged between the support surface and the ink outlet surface and is communicating channels inside the communication pipe. The writing tool can provide a smooth ink outlet effect, can adjust an ink outlet effect by cooperating with a sealing assembly, can reduce a volume of the writing tool and makes the user grip well.

Description

technical field [0001] The invention relates to a writing instrument, in particular to a single-tube porous writing instrument capable of smoothly outputting ink. Background technique [0002] For the structure of existing writing implements with multi-connected pipes, please refer to the No. I326642 of China Taiwan Announcement No. figure 1 As shown, it is provided with a plurality of communicating tubes connected between the ink blocking element and the ink tank, wherein one communicating tube provides the air intake effect, and the other communicating tube provides the ink outlet effect, and the front end of the pen holder of the writing instrument is formed inside Connected to the air channel of the ink blocking element, the external air enters the ink blocking element through the air channel, and then enters the ink tank through the connecting tube providing the effect of air intake, and the ink tank outputs ink to the ink tank through the connecting tube providing the ...
