Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, an ink bag pen with fluent writing comprises a cylindrical pen holder 4 and a pen cap 6 embedded at the front end of the pen holder 4, a pen point 7 is fixed at the front end of the pen holder 4, a pen point 13 is arranged on the inner side of the pen point 7, an external thread fixing table 10 is arranged at the tail of the pen holder 4, a tail rod 1 is installed on the external thread fixing table 10 through threads, an internal fixing table 11 is arranged inside the external thread fixing table 10, an ink bag 2 is embedded on the internal fixing table 11, an ink outlet channel 9 is formed in the center of the internal fixing table 11, an air permeable needle 3 is arranged on one side of the ink outlet channel 9, one end of the air permeable needle 3 is inserted into the ink bag 2, and the other end of the air permeable needle 3 extends out of the front end of the pen holder 4.

Specifically, internal fixation platform 11 and external screw thread fixed station 10, the coaxial setting of pen-holder 4, ink sac 2 and the installation of the 11 tight fit of internal fixation platform, through the installation of the tight fit of the remaining internal fixation platform 11 of ink sac 2, chinese ink reveals the influence and uses when can avoiding using.

Specifically, pen-holder 4 front end annular array shaping has a plurality of fixed slot 14, and nib 13 has a plurality of joint post 12 towards the one end shaping of pen-holder 4, and joint post 12 and fixed slot 14 tight fit installation can be with nib 13 card on pen-holder 4 through the cooperation installation of joint post 12 with fixed slot 14, and the installation of accomplishing nib 13 is fixed.

Specifically, a capillary liquid outlet hole 8 is formed in the pen head 13, one end of the capillary liquid outlet hole 8 corresponds to the position and the size of the ink outlet channel 9, the other end of the capillary liquid outlet hole 8 corresponds to a gap on the pen point 7, ink is transmitted to the pen point 7 from the ink outlet channel 9 through transmission of the capillary liquid outlet hole 8, and the ink flows to paper along the pen point 7 to form an ink mark.

Specifically, the shaping of 4 front ends of pen-holder has arc draw-in groove 15, and nib 7 tight fit buckle can fix nib 7 at 4 tip of pen-holder through the design of arc draw-in groove 15 in arc draw-in groove 15, makes things convenient for the installation of nib 7 to be fixed.

Specifically, the diameter of ventilative needle 3 is no longer than a millimeter, ventilative needle 3 adopts the stainless steel metal to make, the inner chamber diameter of ventilative needle 3 is less than a millimeter, because the inner chamber diameter undersize of

ventilative needle

3, 3 inner chamber pressures of ventilative needle can avoid the chinese ink to flow greatly, ventilative needle 3 gos deep into the tip in the ink sac 2, so set up, outside air can directly get into the 2 upper ends of ink sac through the inner chamber of ventilative needle 3 when perpendicular practical pen, the inside upper end of ink sac 2 is that the air lower extreme is chinese ink, the air does not pass through from in the chinese ink, thereby guarantee the atmospheric pressure invariant in the ink sac 2, do not influence the normal outflow of chinese ink.

Specifically, the position of the pen point 13 corresponding to the air permeable needle 3 is formed with an air vent 5, and the air permeable needle 3 is inserted into the air vent 5, so that the air permeable needle 3 can be prevented from influencing the installation and the disassembly of the pen point 13.

The working principle is as follows:

during the use, take off cap for brush 6, then hold 4 departments of pen-holder and put nib 7 and write on the paper, chinese ink in the ink sac 2 is from going out black passageway 9, capillary liquid outlet hole 8 flows out on nib 7, and adsorb on the paper and form the black trace with the paper contact back, meanwhile, the outside air directly gets into top in the ink sac 2 through the inside cavity of ventilative needle, along with the outflow of chinese ink in the ink sac 2, atmospheric pressure in the ink sac 2 is the same with outside atmospheric pressure all the time, chinese ink normally flows out under the effect of gravity, thereby avoid influencing the chinese ink outflow because of the undersize of the internal pressure of ink sac 2.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
