The pen point, the pen core and the pen of the application are described in detail below with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.

Referring to fig. 1 to 2, the embodiment of the present application provides a pen tip, which can be used for a pen core and a pen, wherein the pen can be a gel ink pen, a cylindrical pen, and the like. The nib includes ball 10, handwriting 20, spring 30, handwriting 20 including fixed pipe 23 with connect in the nib 22 of fixed pipe 23 one end, fixed pipe 23 with nib 22 is inside to be formed with jointly along the appearance chamber 21 that the length direction of handwriting 20 runs through, ball 10 install in nib 22 keeps away from the tip of fixed pipe 23, spring 30 set up in holding the intracavity 21, spring 30 include with the butt portion 31 of ball 10 butt, butt portion 31 with the surface of ball 10 butt is the arc surface, the convex surface on arc surface with ball 10 is relative. The curved surface can guide the ball 10 to roll, so that the ball 10 can roll more smoothly when writing, thereby making the pen writing smoother. In this embodiment, the abutting portion 31 is a U-shaped structure, the bottom surface of the U-shaped end of the U-shaped structure abuts against the ball 10, the overall stability of the U-shaped structure is high, and the structural strength of the spring can be improved.

In some optional embodiments, a concave portion 221 communicating with the cavity 21 is formed at an end of the pen tip 22 away from the fixing tube 23, the ball 10 is movably disposed in the concave portion 221, and a portion of the ball 10 is exposed out of the pen tip 22, so that in a writing state, after the ball 10 is pressed inward, a gap is generated between the concave portion 221 and the ball 10, so that ink is exposed. Further, a first cavity 211 is formed between the inner wall of the recess 221 and the ball 10 for flowing ink. In this embodiment, the cross-sectional diameter of the recess 221 gradually increases along a direction away from the opening, so that the first cavity 211 can partially accommodate the pen ball 10.

Referring to fig. 1 and 2, in some alternative embodiments, the inner wall of the recess 221 at the end away from the fixing tube 23 is curved to facilitate the spring 30 to push the ball 10 back to the original position when the writing state is changed to the non-writing state.

In some alternative embodiments, the cavity 21 includes a plurality of sub-cavities that are sequentially arranged in a communication manner, and the diameters of the sub-cavities gradually increase along a direction away from the pen tip 22, so that the sub-cavities can play a role of uniformly flowing ink. In the present embodiment, the number of the plurality of sub-volumes is seven, which is represented by first sub-volume 212, second sub-volume 213, third sub-volume 214, fourth sub-volume 215, fifth sub-volume 216, sixth sub-volume 217 and seventh sub-volume 218. Further, a sub-cavity with the smallest diameter (i.e. the first sub-cavity 212) of the sub-cavities communicates with the first cavity 211, and the diameter of the sub-cavity with the smallest diameter is smaller than the diameter of the ball 10. It is ensured that the ball 10 is not pressed into the sub-cavity with the smallest diameter (i.e. the first sub-cavity 212) when the ball 10 is pressed in the writing state.

In some alternative embodiments, the abutting portion 31 is located in the sub-cavity with the smallest diameter, and a gap is formed between the abutting portion 31 and the sub-cavity with the smallest diameter for storing and circulating ink.

In some alternative embodiments, a protrusion 25 is disposed in the sub-cavity with the largest diameter (i.e. the seventh sub-cavity 218) of the plurality of sub-cavities, and an end of the spring 30 far from the ball 10 abuts against the protrusion 25, so as to limit the displacement of the spring 30.

In some alternative embodiments, the spring 30 further comprises a connecting rod 32 and a spring body 33. The first end of the connecting rod 32 is connected with the abutting part 31, the second end of the connecting rod 32 is connected with the spring body 33, the outer diameter of the connecting rod 32 is smaller than the outer diameter of the spring body 33 and the outer diameter of the abutting part 31, the space occupied by the spring can be saved, and more ink can be stored in the accommodating cavity 21. Further, the spring 30 further includes a spring tail 34 abutting against the inner wall of the cavity 21, and is connected to one end of the spring body 33 far away from the connecting rod 32, that is, the connecting rod 32 and the spring tail 34 are respectively connected to two ends of the spring body 33. The outer diameter of the spring tail 34 is larger than the outer diameter of the spring body 33, in this embodiment, the spring tail 34 abuts against the protrusion 25, so that the volume of the spring body 33 can be saved, and more ink can be stored in the cavity 21. In addition, the spring tail 34 can buffer the ink flowing into the ink tank from the outside to prevent the ink flowing from being excessively large.

In some alternative embodiments, the outer diameter of the end of the fixed tube 23 close to the pen tip 22 is larger than the outer diameter of the end of the fixed tube 23 far from the pen tip 22, wherein the smaller outer diameter portion can be used as the tail portion 24 of the pen body 20. The cartridge typically includes a barrel, and the small outer diameter of the tail 24 prevents ink leakage at the junction of the tip and the barrel. In this embodiment, the nib 22 is a cone, and the fixing tube 23 and the tail 24 are cylinders, so as to facilitate the assembly of the pen head and the pen barrel.

Referring to fig. 1 and 3, in the non-writing state, the recess 221 is in a state of just catching the ball 10, the ball 10 does not press the spring 30, the first cavity 211 is sealed by the ball 10, and the ink cannot flow out. Referring to fig. 2 and 4, in a writing state, the paper surface presses the ball 10, the ball 10 moves toward the first cavity 211, and since an end of the spring 30 away from the ball 10 abuts against the protrusion 25, the ball 10 applies an axial force to the spring 30 to compress the spring 30, so that a gap is generated between the recess 221 and the ball 10, and ink uniformly flows out of the pen point 22 through the plurality of sub-cavities.

The embodiment of the application also provides a refill, can be used to the pen, and the pen can be gel ink pen, ballpoint pen etc. and the refill include the pen barrel with the nib, the nib is located the front end of pen barrel.
