Abstract
Description
Technical Field
[0001] This utility model relates to the field of ink pen technology, specifically to an ink guiding device for an ink pen. Background Technology
[0002] In the field of writing instruments, the ink pen, as a common writing tool, has the core function of stably and evenly dispensing ink for smooth writing. The ink reservoir, as the channel for storing and delivering ink in the ink pen, is directly related to the ink supply effect and writing quality through its rational design.
[0003] Existing devices have some drawbacks in use. For example, the air pressure balance structure of some existing ink pens is not designed reasonably enough, and the channels for air to enter and exit the reservoir are not smooth enough, resulting in a slow air pressure balance speed. When writing quickly or using the ink pen frequently, it cannot meet the air pressure balance requirements of ink flow in time, which can easily lead to insufficient or excessive ink supply and affect the normal writing process. Utility Model Content
[0004] The purpose of this invention is to provide an ink guiding device for an ink pen, which solves the problem of an unreasonable air pressure balance structure design for ink pens.
[0005] This utility model provides the following technical solution: an ink guiding device for an ink pen, including a pen barrel, a liquid reservoir inserted inside the pen barrel, an ink cartridge threaded onto one end of the pen barrel, and a writing head for discharging ink fixedly installed inside the other end of the pen barrel. Two vent holes are symmetrically opened on the side of the liquid reservoir near the writing head, and a connector is threadedly fixed to the end of the liquid reservoir away from the writing head. Two ink inlet holes are symmetrically opened on the connector.
[0006] As a preferred embodiment of the above technical solution, a cylindrical cavity is provided on the inner side of the liquid storage cylinder, and a suitable ink core is inserted into the cylindrical cavity. The ink core is a cylindrical core body, and the outer wall of the ink core is in contact with the inner wall of the cylindrical cavity.
[0007] As a preferred embodiment of the above technical solution, the connector is connected to the inside of the liquid storage cylinder, and the connector is connected to the inner cavity of the ink cylinder through the ink inlet hole.
[0008] As a preferred embodiment of the above technical solution, the output end of the ink core is in contact with the end of the writing head, and the feed end of the ink core is in contact with the feed end of the connector.
[0009] As a preferred embodiment of the above technical solution, a pen cap is fitted onto the outside of the pen barrel, and multiple weight-reducing holes are arrayed inside the pen cap.
[0010] As a preferred embodiment of the above technical solution, an anti-slip protrusion for assisting in removing the pen cap is fixedly connected to the outer wall of the pen cap.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, the ink reservoir serves as the storage and delivery channel for ink. The design of the vent near the writing head and the connector and ink inlet far from the writing head cleverly achieves smooth ink supply and air exchange. Therefore, through the coordinated work of the vent and ink inlet, air can smoothly enter and exit the ink reservoir, avoiding ink flow problems or excessive ink overflow due to air pressure issues, thus ensuring a smooth and uniform ink dispensing process.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] Example
[0021] like Figures 1-5As shown, this utility model provides a technical solution: an ink guiding device for an ink pen, including a pen barrel 1, a liquid reservoir 11 inserted inside the pen barrel 1, an ink cartridge 12 threadedly connected to one end of the pen barrel 1, and a writing head 13 for discharging ink fixedly installed inside the other end of the pen barrel 1. Two symmetrical vent holes 14 are opened on the side of the liquid reservoir 11 near the writing head 13, and a connector 15 is threadedly fixed to the end of the liquid reservoir 11 away from the writing head 13. Two symmetrical ink inlet holes 16 are opened on the connector 15. In actual use, the ink cartridge 12 supplies ink to the liquid reservoir 11. The two symmetrically arranged vent holes 14 and two symmetrically arranged ink inlet holes 16 can better exchange air inside and outside, so that the ink inside the liquid reservoir 11 flows more smoothly and evenly during the ink dispensing process, avoiding excessive ink. The liquid reservoir 11 flows the ink to the writing head 13 to complete the writing operation.
[0022] As one implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, a cylindrical cavity 111 is formed inside the liquid reservoir 11, and a suitable ink core 17 is inserted into the cylindrical cavity 111. The ink core 17 is a cylindrical core, and the outer wall of the ink core 17 is attached to the inner wall of the cylindrical cavity 111. In actual use, the ink core 17 is a key component connecting the liquid reservoir 11 and the writing head 13. Its main function is to guide the ink in the liquid reservoir 11 to the writing head 13. Since the outer wall of the ink core 17 is attached to the inner wall of the cylindrical cavity 111, the ink will penetrate downward along the fiber structure or capillary channels of the ink core 17 to achieve a continuous supply of ink.
[0023] As one implementation method in this embodiment, such as Figure 4 As shown, connector 15 is connected to the inside of reservoir 11, and connector 15 is connected to the inner cavity of ink cartridge 12 through ink inlet 16. The connection structure at connector 15 also facilitates the flow of air between ink cartridge 12, reservoir 11 and the outside. When ink enters reservoir 11 from ink cartridge 12, air can be exchanged inside and outside through structures such as ink inlet 16 and vent 14, maintaining the air pressure balance during ink delivery and avoiding problems such as poor ink flow or leakage due to air pressure changes.
[0024] As one implementation method in this embodiment, such as Figure 4As shown, the discharge end of the ink core 17 is in contact with the end of the writing head 13, and the feed end of the ink core 17 is in contact with the feed end of the connector 15. This contact design helps to transmit and balance the pressure of the ink during the transmission process. When the writing head 13 consumes ink, the negative pressure generated at the writing head 13 will be transmitted to the ink core 17 through the contact part, thereby causing the ink in the ink cartridge 12 to continuously flow into the ink core 17 and reach the writing head 13 under pressure. At the same time, it can also ensure that the pressure of each part is relatively balanced, and avoid the situation of local ink accumulation or insufficient supply.
[0025] As one implementation method in this embodiment, such as Figure 5 As shown, the pen barrel 1 is fitted with a pen cap 18 on the outside. The pen cap 18 has multiple weight-reducing holes 19 arranged in an array inside to reduce the weight of the pen cap 18, making it more convenient for users to carry, especially when carrying the pen for a long time.
[0026] As one implementation method in this embodiment, such as Figure 1 As shown, an anti-slip protrusion 181 for assisting in pulling out the pen cap 18 is fixedly connected to the outer wall of the pen cap 18. The protrusion provides a clear force position for the fingers, allowing the user to grip the pen cap 18 more accurately when pulling out the pen cap 18 and concentrate the force on the protrusion, thereby completing the pulling action more effectively and improving the accuracy and convenience of the operation.
[0027] Working principle: When the user needs to write with the ink pen, a negative pressure is generated at the writing head 13. This negative pressure is transmitted to the ink core 17 through the contact part between the dispensing end of the ink core 17 and the end of the writing head 13. Under the action of negative pressure, the ink in the ink cartridge 12 enters the connector 15 through the ink inlet 16, and then enters the ink core 17 that is in contact with the dispensing end from the connector 15. The ink permeates along the fiber structure or capillary channels of the ink core 17. Since the outer wall of the ink core 17 is in contact with the inner wall of the cylindrical cavity 111, the ink can be stably conducted to the writing head 13 that is in contact with the dispensing end, so as to achieve a continuous supply of ink and ensure that the ink is dispensed evenly and smoothly during the writing process.
[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
