[0036] For those skilled in the art to better understand the technical solutions of the present application, the present application will be described in further detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present application.

[0037] Please refer to Figures 1-8 and Figure 10 and Figure 11 The pen 10 of the present application comprises a barrel 100, a refill 200 and a nib assembly 300.

[0038] The refill 200 is arranged in the barrel 100, and the front end of the refill 200 is provided with a sealing membrane 230. The nib assembly 300 comprises a support 310 and a nib 320. The support 310 is sleeved on the front end of the barrel 100, and is provided with a rotation stop slot 311. The front end of the refill 200 is inserted into the rotation stop slot 311 to stop rotation with the rotation stop slot 311. The side wall of the rotation stop slot 311 is provided with a penetration avoidance opening 312. The nib 320 is in the form of a sheet and comprises an ink output section 21, a sleeve section 22 and a penetration section 23.

[0039] In combination with Figure 5 Please refer to Figure 6 , the ink output section 21 is provided with a writing ink capillary slit 24 for contacting a writing surface to output ink marks through the writing ink capillary slit 24. The sleeve section 22 is integrally connected with the ink output section 21 and is sleeved on the support 310. The penetration section 23 is provided with an ink guide capillary slit 25, the front end of the penetration section 23 is integrally connected with the rear end of the ink output section 21, and the front end of the ink guide capillary slit 25 is in communication with the rear end of the writing ink capillary slit 24. The rear end of the penetration section 23 is formed with a spike 26, and the rear end of the ink guide capillary slit 25 extends to the spike 26. In combination with Fig Figures 10-11 Please refer toFigure 6 、 Figure 1 、 Figure 3 and Figure 8 The rear end of the piercing section 23 extends into the rotating slot 311 through the piercing avoiding hole 312, and the spike 26 pierces the sealing film 230 to enable the ink guiding capillary slit 25 to enter the refill 200.

[0040] In this way, since the spike 26 in the nib 320 pierces the sealing film 230, the ink 211 in the refill 200 can enter the ink guiding capillary slit 25 under the capillary adsorption of the ink guiding capillary slit 25 in the nib 320 and the gravity of the ink 211 itself, and then be guided to the writing ink capillary slit 24 of the nib 320 by the ink guiding capillary slit 25, and further be outputted by the contact between the writing ink capillary slit 24 and the writing surface. In this way, the structure of the fountain pen 10 can be simplified without using the capillary tube in the tongue.

[0041] It should be noted that in an example, the cross section of the rotating slot 311 is non-circular, and the cross section of the front end of the refill 200 is non-circular and matched with the rotating slot 311, so that the rotating slot 311 can be matched with the front end of the refill 200 to prevent the rotation of the refill 200 relative to the support 310, but is not limited thereto. It should be understood that since the rotation of the refill 200 relative to the support 310 will squeeze the piercing section 23 to damage the nib 320, the rotation of the refill 200 relative to the support 310 needs to be avoided.

[0042] Further, referring to Figures 5-6 The ink guiding capillary slit 25 gradually expands from the front end of the ink guiding capillary slit 25 to the rear end of the ink guiding capillary slit 25, and the rear end of the ink guiding capillary slit 25 is spaced apart from the edge of the spike 26.

[0043] If the rear end of the ink guiding capillary slit 25 extends to communicate with the edge of the spike 26, after the spike 26 pierces the sealing film 230, the deformation restoring force of the sealing film 230 will cause the ink guiding capillary slit 25 to shrink greatly, thereby affecting the function of the ink guiding capillary slit 25. Therefore, by spacing the rear end of the ink guiding capillary slit 25 from the edge of the spike 26, the edge portion of the spike 26 can be used to support the ink guiding capillary slit 25 to keep the ink guiding capillary slit 25 in an open state. The deformation restoring force of the sealing film 230 can enable the pierced part of the sealing film 230 to tightly adhere to the outer surface of the piercing section 23, thereby achieving the function of preventing ink leakage.

[0044] Further, referring to Figures 5-6, from the side of the nib 320 facing the support 310 to the side of the nib 320 facing away from the support 310, the gap of the writing ink capillary slit 24 gradually expands. In this way, the ink 211 can be further prevented from leaking to the side of the nib 320 facing the support 310 during transmission in the writing ink capillary slit 24, so that the ink 211 can be conducted to the front end of the writing ink capillary slit 24 to output ink marks when the front end of the writing ink capillary slit 24 contacts the writing surface.

[0045] Further, referring to Figures 5-6 , the nib 320 is formed with a curved portion 29 at the part outside the two side edges of the window area 27 opposite to the extension direction of the ink guide capillary slit 25. The curved portion 29 gradually curves to the inside of the nib 320 in the direction away from the window area 27. In this way, when the front end of the writing ink capillary slit 24 is pressed against the writing surface, the ink outlet section 21 can expand the ink guide capillary slit and the writing ink capillary slit 24 due to the reaction force of the writing surface and the pulling force of the curved portion 29, so as to facilitate the output of ink.

[0046] Further, referring to Figures 5-6 , the front end of the sleeve joint portion 22 is connected to the rear end of the ink outlet section 21, and the window area 27 is formed between the front end of the sleeve joint portion 22 and the rear end of the ink outlet section 21. The window area 27 exposes the penetration avoiding opening 312.

[0047] , the rear end of the writing ink capillary slit 24 extends to the edge of the window area 27 close to the writing ink capillary slit 24. The front end of the penetration section 23 is integrally connected to the edge of the window area 27 close to the writing ink capillary slit 24. The rear end of the penetration section 23 extends to the inside of the sleeve joint portion 22, which is the side of the sleeve joint portion 22 for receiving the support 310. In this way, the window area 27 facilitates observation of the position of the sealing film 230 when the penetration section 23 pierces the sealing film 230.

[0048] Further, referring to Figures 5-6 , from the front end of the penetration section 23 to the rear end of the penetration section 23, the penetration section 23 gradually extends to the inside of the sleeve joint portion 22. In this way, the penetration section 23 is facilitated to pierce the sealing film 230. Optionally, the penetration section 23 is provided with a plurality of or one ink guide capillary slit 25.

[0049] Further, in combination with 2- Figure 3 , referring to Figure 5 , the inside of the sleeve joint portion 22 is formed with a sleeve groove 28, which is sleeved on the support 310. In this way, the sleeve joint portion 22 is facilitated to tightly sleeve the support 310.

[0050] Further, referring to Figures 2-4The support member 310 includes a pen sleeve section 313 and a connector insertion section 314. The pen sleeve section 313 is sleeved onto the front end of the pen barrel 100. The rear end of the connector insertion section 314 is connected to the front end of the pen sleeve section 313. The connector insertion section 314 is provided with an anti-rotation slot 311. Optionally, the pen sleeve section 313 is detachably sleeved onto the front end of the pen barrel 100, so that when the pen tip assembly 300 needs to be replaced, the pen sleeve section 313 of the pen tip assembly 300 can be removed from the front end of the pen barrel 100, and then the pen sleeve section 313 of the new pen tip assembly 300 can be sleeved onto the front end of the pen barrel 100.

[0051] Furthermore, combined Figures 1-3 See Figure 7 , Figures 10-11 The pen refill 200 includes an oil tube 210, a pen refill anti-rotation connector 220, and a sealing film 230.

[0052] A refill anti-rotation connector 220 is disposed at the front end of the ink tube 210 and communicates with the front end of the ink tube 210. A sealing membrane 230 is disposed at the front end of the refill anti-rotation connector 220. The refill anti-rotation connector 220 is inserted into the anti-rotation slot 311 to prevent rotation. Thus, the refill 200 and the anti-rotation slot 311 are removable, allowing the refill 200 inserted into the anti-rotation slot 311 to be easily removed and a new refill 200 inserted, facilitating replacement of the refill 200 inserted into the anti-rotation slot 311. Optionally, the sealing membrane 230 is formed in a cap shape to cover the front end of the anti-rotation connector, but is not limited to this. Optionally, xanthan gum is added to the ink 211, giving the ink 211 a higher viscosity, thus making the fountain pen 10 less prone to ink leakage, but is not limited to this.

[0053] Further, see Figures 10-11 The front end of the pen refill anti-rotation connector 220 is flat, and the inner cavity of the front end of the pen refill anti-rotation connector 220 is also relatively flat. The rear end of the insertion section 23 pierces the sealing membrane 230, allowing the ink-guiding capillary slit 25 to enter the pen refill anti-rotation connector 220. This facilitates the rear end of the insertion section 23 to pierce the sealing membrane 230 and facilitates the ink-guiding capillary slit 25 to absorb the ink 211 in the pen refill 200.

[0054] For example, combined Figure 1 See Figures 9-10 The pen refill 200 includes ink 211, finishing ink 212, and a stopper 213, but is not limited to these. Ink 211 is disposed within the ink tube 210, and finishing ink 212 is disposed within the ink tube 210 and located at the end of ink 211. The stopper 213 is disposed at the end of the ink tube 210, and a vent 214 is provided in the middle of the stopper 213, penetrating through the stopper 213. In this manner, the finishing ink 212 and the stopper 213 prevent the backflow of ink 211 within the ink tube 210 along the tube wall.

[0055] For example, referring to Figures 1-3 The pen 10 comprises a cap 400 connected to the front end of the pen barrel 100 and covering the nib 320, so as to prevent dust and collision of the nib 320 in the non-use state of the pen 10.

[0056] The nib of the pen provided by the present application is the same as the nib 320 in the above-mentioned embodiment of the pen 10, and will not be described here again.

[0057] The nib assembly provided by the present application is the same as the nib assembly 300 in the above-mentioned embodiment of the pen 10, and will not be described here again.

[0058] The ink cartridge provided by the present application is the same as the ink cartridge 200 in the above-mentioned embodiment of the pen, and will not be described here again.

[0059] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
