Description

Technical Field

[0001] The invention relates to a fountain pen tip and a fountain pen. Background Art

[0002] The tip of an ordinary fountain pen usually consists of an arc-shaped pen tip and a pen feed. The pen tip is a metal plate. The ink is mainly supplied downward through the gap between the metal plate and the pen feed. After reaching the center hole in the middle of the metal plate pen tip, it continues to flow downward along a gap to the tip to achieve writing.

[0003] The main drawback of this type of nib is that the amount of water discharged is difficult to control, making it difficult to write strokes of varying widths, such as calligraphy.

[0004] CN2092431U discloses a hard pen nib for writing medium and large characters. The nib is provided with a plurality of core holes and a plurality of slit water guide grooves to assist in setting the tip of the nib into an arc shape, thereby increasing the contact area between the nib and paper, thickening the nib or increasing the flow rate and widening the stroke, thereby achieving the purpose of writing medium and large characters.

[0005] The calligraphy pen tip disclosed in CN2072909U has a tip portion arranged in an arc shape.

[0006] The above-mentioned pen tip still relies on the gap water groove on the metal plate pen tip to transport ink, and the control of the water flow is still difficult. First, the water flow is prone to fluctuate, and second, the ink is prone to dryness, agglomeration and blockage between the pen tip and the pen tongue, in the core hole and in the gap, affecting normal use.

[0007] Therefore, a kind of tap water hard pen nib and tap water hard pen with stable water discharge, easy controllable stroke width and ink not easily blocked by drying and agglomeration phenomenon just arise at the historic moment. Summary of the Invention

[0008] The invention aims to provide a fountain pen tip and a fountain pen with stable ink flow, easy-to-control stroke width and ink that is not easily clogged due to drying and agglomeration.

[0009] The object of the present invention is achieved through the following structure: a fountain pen tip includes a pen tip, characterized in that the pen tip includes a body (11), the body (11) is a tubular body with a semicircular cross-section, the tubular body is composed of an inner arc surface and an outer arc surface to form an ink supply channel (12), and the tubular body is in a contracted shape with a larger upper portion and a smaller lower portion.

[0010] At least, the upper end of the tubular body is open to form an ink inlet, or at least one ink suction hole (16) is provided on the inner curved surface of the tubular body, and the ink suction hole (16) is a hole on the inner curved surface of the tubular body connected to the ink supply channel (12), and a pen tongue (17) is provided on the inner curved surface of the tubular body.

[0011] A writing head is provided at the lower portion of the tubular body, the writing head including an ink storage chamber (14), the upper portion of the ink storage chamber (14) being connected to an ink delivery channel (12) of the body (11), the lower end portion of the ink storage chamber (14) being a rectangular plane constituting a writing surface, an ink outlet (15) being provided on the writing surface, the ink outlet (15) being at least one long strip-shaped slit on the writing surface extending from the writing head ink storage chamber (14) to the outside.

[0012] At least the writing head or the body (11) is provided with an air inlet and outlet hole (13).

[0013] Furthermore, the writing surface is preferably an arc surface along the length direction of the ink outlet (15).

[0014] Furthermore, an ink-absorbing cotton is provided in the writing head ink storage chamber (14).

[0015] Furthermore, an ink-absorbing cotton is provided in the ink supply channel (12).

[0016] Furthermore, a water diversion sheet (18) is provided in the ink delivery channel (12), and the water diversion sheet (18) is a thin sheet extending from the upper end of the body (11) downward to the ink storage chamber (14). A first water diversion slit (182) is provided on the thin sheet in the ink delivery channel (12), and the first water diversion slit (182) is a longitudinal slit on the thin sheet. A second water diversion slit (181) is provided on the thin sheet in the ink storage chamber (14), and the second water diversion slit (181) is a transverse slit on the thin sheet. There are at least two second water diversion slits (181), and the lower end of the first water diversion slit (182) is connected to the second water diversion slit (181) at the upper portion.

[0017] Furthermore, the first water diversion slit (182) can be a slit extending from top to bottom, or at least one water diversion groove extending from top to bottom, preferably two or more parallel grooves.

[0018] Furthermore, the above-mentioned fountain pen tip can constitute a fountain pen, which includes a pen cap, a water storage mechanism (23) and a pen tip connecting terminal (21), and a pressure reducing mechanism (22) is provided between the water storage mechanism (23) and the fountain pen tip.

[0019] Compared with the prior art, the advantages of the present invention are: stable ink flow, easy control of stroke width, particularly suitable for writing artistic fonts or large characters, the entire nib body has very few parts and areas in contact with the air, and except for the ink outlet and air inlet and outlet of the writing part, the nib body has no contact with the air, so the ink is not likely to clog the pen tip due to drying and agglomeration.
