Description

Technical Field

[0001] This utility model relates to the field of marker technology, and in particular to a single-cavity double-ended alcohol marker. Background Technology

[0002] Marker ink is usually stored in liquid form within the pen barrel. The ink has good fluidity, especially alcohol-based marker ink, which has excellent fluidity. When markers are transported from low-altitude to high-altitude areas, the increased altitude causes a drop in air pressure. If there are air gaps in the ink chamber, this can cause a sudden, large outflow of ink (also known as "ink bursting"), resulting in smudges and rendering the marker unusable.

[0003] In existing technology, single-tipped markers can prevent ink splattering caused by the above reasons by controlling the air gap in the ink chamber. However, in order to obtain rich lines for calligraphy and drawing, markers are usually designed with a double-tipped structure with different nibs at both ends. However, because the two ends of the double-tipped structure are connected, it is more prone to ink splattering due to the above reasons, especially alcohol markers with highly fluid ink.

[0004] Currently, some double-ended markers on the market incorporate two separate ink chambers within the pen barrel to supply ink to the tips at both ends, thus preventing ink splattering caused by the aforementioned reasons. While this design avoids ink splattering, it can easily result in one end running out of ink while the other end still has a large amount of ink remaining, leading to significant ink waste even after the marker malfunctions.

[0005] Therefore, there is an urgent need to design a single-cavity double-ended alcohol marker that, while employing a double-ended structure and preventing ink bursts, avoids ink waste. Summary of the Invention

[0006] The technical solution of this utility model is as follows:

[0007] A single-cavity double-ended alcohol marker, characterized in that: it includes a pen barrel with an ink cavity inside, and each end of the pen barrel is provided with an ink control component communicating with the ink cavity;

[0008] The ink control assembly includes a pen tip, one end of which is airtightly connected to the pen barrel, and the other end of which is provided with a pen tip fixing hole for mounting the pen tip; the end of the pen tip near the pen barrel is provided with an airtightly connected water inlet seat, the water inlet seat is provided with a water inlet hole that passes through the water inlet seat, and a slidingly fitted water inlet core is provided on the water inlet hole.

[0009] At least one of the ink control components has a sealing membrane on the water inlet seat to close the water inlet hole.

[0010] Furthermore, the two ink control components are respectively factory-set and user-set:

[0011] In the factory-configured ink control assembly, the pen tip is provided on the pen nozzle, and the pen tip is connected to the ink core;

[0012] In the user-defined ink control components, the water inlet base is equipped with a sealing membrane that closes the water inlet hole.

[0013] Furthermore, the pen tip fixing hole and the water inlet hole are coaxial.

[0014] Furthermore, the sealing film is a plastic or aluminum-plastic film.

[0015] Furthermore, an ink-absorbing body that encloses the ink-absorbing core and / or pen tip is provided between the pen tip and the ink-absorbing base.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0023] It should be noted that when a component is said to be "fixed" to another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," "up," "down," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0026] like Figure 1 As shown, a single-cavity double-ended alcohol marker includes a pen barrel 10 with an ink cavity 11 inside, and each end of the pen barrel 10 is provided with an ink control component communicating with the ink cavity 11.

[0027] The ink control assembly includes a pen tip 20, one end of which is airtightly connected to the pen barrel 10, and the other end is provided with a pen tip fixing hole 21 for mounting a pen tip 70; the end of the pen tip 20 near the pen barrel 10 is provided with an airtightly connected water inlet seat 30, the water inlet seat 30 is provided with a water inlet hole 31 that passes through the water inlet seat 30, and a slidingly sleeved water inlet core 40 is provided on the water inlet hole 31.

[0028] At least one of the ink control components has a sealing membrane 60 on the water inlet seat 30 to close the water inlet hole 31.

[0029] Furthermore, the two ink control components are respectively factory-set and user-set:

[0030] In the factory-configured ink control assembly, the pen tip 20 is provided with a pen tip 70, which is connected to the ink core 40;

[0031] In the user-defined ink control component, the water inlet base 30 is provided with a sealing membrane 60 that closes the water inlet hole 31.

[0032] In this embodiment, the manufacturer has pre-installed the pen tip 70 in the factory-set ink control assembly. Because the ink inlet 31 in the user-set ink control assembly is sealed with a sealing membrane 60, the ink chamber of the marker can only communicate with the external atmosphere on one side. Therefore, ink bursts caused by pressure changes can be avoided by controlling the air gap within the ink chamber. Actual testing shows that this embodiment can achieve no ink leakage at -40 kPa.

[0033] The ink control component is set by the user. The manufacturer provides one or more pen tips 70. The user inserts the pen tip 70 into the pen mouth 20 through the pen tip fixing hole 21 as needed. At the same time as the pen mouth 20 is inserted, the pen tip 70 contacts the ink core 40 and breaks through the sealing membrane 60, so that the ink core 40 is inserted into the ink inside the pen barrel 10. The ink flows along the ink core 40 to the pen tip 70, thereby achieving smooth writing.

[0034] Furthermore, to facilitate the user's insertion of the pen tip 70, the pen tip fixing hole 21 and the water inlet hole 31 are coaxial.

[0035] Furthermore, in order to make it easy for the water-guiding core 40 to puncture the sealing membrane 60, the sealing membrane 60 is a plastic or aluminum-plastic film.

[0036] Furthermore, an ink-absorbing body 50 is provided between the pen tip 20 and the ink-absorbing base 30, which encloses the ink-absorbing core 40 and / or the pen tip 70.

[0037] When gravity, air pressure and temperature change, the ink in the pen barrel 10 may suddenly gush out in large quantities (also known as "ink burst"). In this embodiment, an ink absorber 50 is provided to absorb the ink that flows out when the ink bursts, thereby avoiding or reducing the large amount of ink flowing out from the pen tip 70.

[0038] Furthermore, there is only one ink cavity 11.

[0039] In this embodiment, only one ink chamber 11 is provided to supply ink to both ends of the pen tip 70. This can prevent ink bursting and avoid the ink waste caused by setting two ink chambers in the prior art.

[0040] Furthermore, the pen tip 20 is provided with a pen cap 80 that covers the pen tip 70.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
