[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. 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 creative labor fall within the scope of protection of the present application.

[0045] Please refer to Figures 1-5 The present application provides the following technical solutions:

[0046] A refill for correction fluid and glue, comprising a pipe body 1 with an internal cavity, both ends of the pipe body 1 being open ends, the internal cavity of the pipe body 1 being in communication with both ends of the pipe body 1 to form a through cavity. The internal cavity of the pipe body 1 is filled with liquid material. The liquid material in the internal cavity of the pipe body 1 comprises a first liquid 11 and a second liquid 12, wherein the first liquid 11 is correction fluid or glue; the second liquid 12 is tail oil, and the second liquid 12 is filled in the end of the first liquid 11 away from the pen head connector 2, and the second liquid 12 plays a sealing role on the first liquid.

[0047] A pen head connector 2 is arranged at one end of the pipe body 1, the internal cavity of the pen head connector 2 is in communication with the internal cavity of the pipe body 1; the pen head connector 2 is a variable diameter structure corresponding to the pipe body 1 and the pen head 3 at both ends. A pen head 3 is arranged at the end of the pen head connector 2 away from the pipe body 1, the pen head 3 has a liquid outlet at one end and is connected to the pen head connector 2 at the other end; the internal cavity of the pen head 3 is empty. A partition 31 is fixedly arranged in the internal cavity of the pen head 3, the partition 31 divides the internal cavity of the pen head 3 into a first chamber 32 and a second chamber 33, the first chamber 32 is close to the pen head connector 2, and the second chamber 33 is close to the liquid outlet of the pen head 3. The second chamber 33 is a spherical cavity. A liquid guide groove 35 is arranged on the partition 31, the liquid guide groove 35 penetrates the partition 31, the first chamber 32 and the second chamber 33 are in communication through the liquid guide groove 35, so that the first chamber 32 and the second chamber 33 are in communication. A sealing element 34 is arranged in the second chamber 33, the sealing element 34 is a sphere, i.e. the sealing element 34 is rotatably arranged on the inner side of the liquid outlet of the pen head 3.

[0048] Through the structure of the present solution, different from the conventional correction fluid or glue storage form, the present solution utilizes the structure of the pipe body 1 to place the first liquid 11, that is, the correction fluid or glue, in the pipe body 1 which is penetrated at both ends, and utilizes the tail oil 12 to seal. At the same time, by means of the structure of the pen head 3 combined with the spherical sealing member 34, the correction fluid and glue can be applied like a conventional writing pen, effectively controlling the application area, and because the external structure is similar to the conventional pen core as a whole, it can be used in combination with the existing pen barrel, making the user more flexible and controllable when applying, and facilitating placement in the stationery bag.

[0049] On the basis of the above-mentioned embodiment, the pen head connecting piece 2 includes a first connecting part and a second connecting part, the first connecting part is inserted into the inside of the pipe body 1 and is attached to the inner wall of the pipe body 1. The second connecting part is used to connect with the end of the pen head 3, and the end of the pen head 3 is inserted into the inside of the second connecting part and is attached to the inner wall of the second connecting part.

[0050] An annular plate is further arranged outside the pen head connecting piece 2, and the annular plate is arranged at the end of the first connecting part. When the pen head connecting piece 2 is inserted into the inside of the pipe body 1, the annular plate is attached to the end surface of the pipe body 1.

[0051] On the basis of the above-mentioned embodiment, the liquid guide groove 35 includes a middle groove 351 and a plurality of edge grooves 352. The middle groove 351 is arranged at the center of the partition piece 31, and the edge grooves 352 are arranged in a circumferential direction around the middle groove 351.

[0052] The liquid guide groove 35 can play a role of uniformly distributing the first liquid 11 towards the sealing member 34, and at the same time of connecting the first chamber 32 and the second chamber 33, so that the first liquid 11 is uniformly distributed on the sealing member 34 and is applied at the required position as the sealing member 34 rotates.

[0053] On the basis of the above-mentioned embodiment, the structure of the liquid guide groove 35 can be various, such as the middle groove 351 being a circular groove and the edge groove 352 being an arc-shaped groove. In the present solution, because the first liquid 11 is correction fluid or glue, the viscosity of which is relatively high, the structure form in which the middle groove 351 and the edge groove 352 are connected is adopted.

[0054] The present solution gives a specific structure form of the liquid guide groove 35, but the implementation of the present solution is not limited to this one. Referring to Figures 4 to 11 , the middle groove 351 is a cylindrical through groove, and the edge groove 352 is a long strip-shaped through groove. The edge groove 352 is arranged in a radial shape around the middle groove 351, one end of the edge groove 352 is connected with the middle groove 351, and the other end extends towards the radial direction of the middle groove 351.

[0055] As Figures 5 to 7As shown, because the overall structure of the pen tip 3 is also a variable diameter structure, the end of the side groove 352 facing the second chamber 33 has its groove opening directly opened to the inner side of the inner wall of the second chamber 33. The side of the side groove 352 facing the first chamber 32 has a gap between its groove opening and the inner side of the first chamber 32.

[0056] Furthermore, the partition 31 and the liquid guiding channel 35 have a flared structure on the side facing the first chamber 32, that is, some of them facing the first chamber 32 have a structure that converges from the edge to the center, and the center is recessed towards the second chamber 33. This structure allows for better convergence of the first liquid 11.

[0057] The aforementioned pen tip structure 3 in this solution is sufficient for normal use. It is best to add an external pen cap to ensure the first liquid 11 does not dry out. If you wish to further improve the sealing effect of the pen tip, the following structural form can also be adopted. See [link / reference]. Figures 8 to 11 The pen tip 3 also has a support member 36 inside. The support member 36 is an elastic member and is located in the first chamber 32. One end of the support member 36 extends into the second chamber 33 and abuts against the seal member 34. A limiting member 37 is provided in the first chamber 32 and abuts against the end of the support member 36 away from the seal member 34.

[0058] By setting the support member 36, the support member 36 abuts against the seal member 34, thereby better sealing the pen tip 3 and avoiding the problem of correction fluid or glue drying.

[0059] Based on the above implementation plan, see Figure 8 The support member 36 is a spring, and its whole structure is a spiral structure. The outer diameter of the support member 36 is gradually changing. The end facing the pen tip connector 2 is the end with a large outer diameter, and the end facing the seal member 34 is the end with a small outer diameter.

[0060] Furthermore, the pitch of the support member 36 is also variable. For ease of explanation, let's take... Figure 10 Taking the direction as an example, the end of the support member 36 facing the pen tip connector 2 is... Figure 10 The pitch value is smaller at the right end of the diagram, gradually increasing towards the center, and then gradually decreasing towards the left. However, the pitch at the left end is greater than that at the right end.

[0061] A short straight rod is provided at the left end of the support member 36. The straight rod is connected to the spring of its spiral part. The straight rod passes through the liquid guide groove 35 and abuts against the seal member 34.

[0062] On the basis of the above-mentioned embodiments, the ball diameter of the sealing member 34 of the present solution is 1.0 mm, the number of the edge grooves 352 is three when the first liquid 11 is correction fluid, and the number of the edge grooves 352 is five when the first liquid 11 is glue.

[0063] The numerical values given in the present solution are not fixed and can be adaptively changed according to actual needs.
