Problems solved by technology

If the aperture is too large or the diameter of the ink core is too small, it may cause too much ink at the tip of the nib, causing ink leakage; if the aperture is too small or the diameter of the ink core is too large, it may cause the ink core to fail to be installed. The ink chamber, or the ink core completely blocks the through hole at the front end of the ink chamber, causing poor water outlet
[0004] Therefore, in the prior art, the processing accuracy requirements for the ink lead core and the through hole at the end of the ink chamber are relatively high, resulting in relatively high processing costs for the entire pen.

Embodiment 1

[0032] Such as Figure 1~5 As shown, the pen includes a pen cap 1 and a pen holder 2; the pen cap is provided with a pen clip 11, the front end of the pen holder 2 is a nib 21 for writing, and the pen holder 2 is provided with an ink chamber 26 and a built-in Cotton tube cavity 23 of cotton tube 24, cotton tube cavity 23 is arranged between ink chamber 26 and nib 21; The connected ink core 25; the pen holder 2 is provided with a nib 22 and a hand guard 32 which are convenient for the user to hold, and the end of the pen holder 2 is provided with a tail plug 31 . This is a one-piece structure of ink-leading core and nib.

[0033] Wherein, the position of the front end 27 of the ink chamber is provided with a through hole 28 for passing through the ink core 25, and the section of the ink lead core is circular; correspondingly, the through hole provided at the front end 27 of the ink chamber is then It is a polygonal hole with a polygonal cross-section, such as image 3 shown....

Embodiment 2

[0036] Such as Image 6 As shown, the pen includes a pen cap 1 and a penholder 2; the front end of the penholder 2 is a nib 21 for writing, and the penholder 2 is provided with an ink chamber 26 and a cotton tube chamber 23 with a cotton tube 24 built in, and the cotton tube The cavity 23 is arranged between the ink chamber 26 and the nib 21; the pen holder 2 is also provided with an ink-leading core 25 which runs through the second half of the ink chamber front end 27 and the cotton tube 24 in the cotton tube chamber 23; the second half of the nib 21 Also inserted in the cotton tube 24, the ink leading core 25 communicates with the nib 21 through the cotton tube 24. The ink core 25 leads the ink in the ink chamber 26 into the cotton tube 24, and the nib 21 sucks the ink in the cotton tube 24 to realize the writing function. This is a split structure of the ink core and the nib.

[0037] Same as in Embodiment 1, the position of the front end 27 of the ink chamber is also pro...

Embodiment 3

[0039] The structure of embodiment three is as Figure 7 As shown in , the difference from the structure of the pen in the second embodiment is that the ink-leading core runs through the entire ink chamber in the length direction.

Abstract

The invention discloses a pen, which comprises a pen point, an ink chamber, and an ink leading refill communicated with the pen point and the ink chamber, wherein the end part of the ink chamber is provided with a through hole for the ink leading refill to pass; and the cross section of the through hole and a cross section of the ink leading refill corresponding to the through hole are alternatively round and non-round. Because the cross section of the ink leading refill and the cross section of the through hole on the end part of the ink chamber are alternatively round and non-round, a natural ink communicating gap is formed between the ink leading refill and the end part of the ink chamber due to the shape difference; and even if the diameter of the ink leading refill is larger, the ink leading refill can lead out ink in the ink chamber as long the ink leading refill can be arranged in the through hole on the end part of the ink chamber; therefore, the requirement on processing accuracy of the ink leading refill or the through hole on the end part of the ink chamber is reduced, and the processing cost is correspondingly reduced.

Description

technical field [0001] The invention relates to the technical field of writing instruments, and more specifically, relates to a pen using inks of various colors. Background technique [0002] Pens using various inks usually include a nib, an ink chamber and an ink lead. The ink chamber is used to store inks of various colors. Achieve flow and lasting writing. [0003] Because the ink core needs to draw ink from the ink chamber, the ink core passes through the end of the ink chamber and enters the ink chamber. The end of the ink chamber is provided with a through hole for the ink core to pass through, and the ink core and the end of the ink chamber The cross-sections of the through holes are all circular, therefore, the aperture of the circular through hole at the end of the ink chamber needs to be slightly larger than the diameter of the ink core. If the aperture is too large or the diameter of the ink core is too small, it may cause too much ink at the tip of the nib, cau...
