Description

Technical Field

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

[0002] Markers are widely used in writing and drawing due to their rich colors, stroke effects, and ease of use;

[0003] However, traditional double-ended markers have the following problems due to structural limitations:

[0004] 1. Double-ended markers usually have a fine tip on one end and a thick tip on the other end, and the two ends are connected. If the pressure in the ink reservoir is slightly high, the fine tip cannot buffer the flow, which can easily lead to the ink dripping too fast.

[0005] 2. Due to the poor resistance to negative pressure of the single-channel ink storage chamber, when the temperature or air pressure changes, the air and ink inside the chamber expand, which increases the air pressure inside the chamber, causing the ink to be squeezed out and easily resulting in ink leakage.

[0006] Therefore, there is an urgent need to design a double-ended single-pass marker pen. By setting ink control components at the ends of the pen tips near the ink storage chamber, the connectivity between the ink storage chamber and the pen tips at both ends can be controlled. This solves the problem in existing double-ended marker pens where ink leakage or rapid ink dripping is easily caused by increased pressure in the ink storage chamber due to the connection between the two ends. This reduces ink dripping and prevents ink leakage. Utility Model Content

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0008] A double-ended single-pass marker, comprising a barrel and a tip, characterized in that:

[0009] The pen barrel is a container-shaped structure with openings at both ends and an ink storage cavity inside. A pen tip with a hollow through structure is provided at each of the two openings of the pen barrel.

[0010] One end of the pen tip is provided with an ink control component, and the other end is provided with a pen nib;

[0011] An ink absorber for absorbing liquid ink is provided between the pen tip and the ink control component;

[0012] The ink control assembly includes an ink control valve body and a ball movably disposed within the ink control valve body;

[0013] One end of the ink control valve body is provided with an ink inlet hole that communicates with the ink storage chamber, and the other end is provided with an ink outlet hole that contacts the ink absorption body.

[0014] When the marker is held upright or at a set angle, under the action of gravity, the upper ball blocks the ink inlet hole of the corresponding ink control valve, and the lower ball blocks the ink outlet hole of the corresponding ink control valve.

[0015] Preferably, the ink control valve body includes a valve seat that is sleeved with the pen tip;

[0016] A valve cover is provided at the ink inlet side opening of the valve seat, and a funnel section with a gradually decreasing inner diameter is provided at the ink outlet side.

[0017] The ink outlet of the funnel section forms an ink outlet hole that contacts the ink-absorbing body;

[0018] One end of the valve cover is sealed and engaged with the valve seat, and the other end is a funnel end with a gradually decreasing inner diameter;

[0019] The end face of the funnel end is provided with an ink inlet hole;

[0020] The ball is movably disposed within the ink control cavity formed between the valve seat and the valve cover.

[0021] Preferably, a groove is provided at the contact point between the funnel section and the sphere.

[0022] Preferably, the end of the funnel section away from the valve seat is provided with an ink-guiding section that contacts the ink-absorbing body;

[0023] The ink guide section is provided with an ink passage hole that connects the ink control cavity and the ink absorber.

[0024] The end of the ink passage that contacts the ink absorber has a notch.

[0025] Preferably, the ink passage extends to the point where it contacts the sphere within the funnel section.

[0026] Preferably, the cross-section of the ink passage is polygonal.

[0027] Preferably, the ink absorber is a flexible fiber with dense pores, and the pen tip and ink passage are respectively inserted into the interior of the ink absorber.

[0028] Preferably, the sphere is made of stainless steel or ceramic material.

[0029] Preferably, the outside of the pen tip is provided with a pen cap that covers the pen tip, and the pen cap is detachably connected to the pen tip or pen barrel.

[0030] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0031] 1. This utility model provides an ink control assembly consisting of an ink control valve and a ball at each end of the pen tip near the ink storage chamber. When the marker is held upright or at a set angle, under the influence of gravity, the upper ball blocks the upper ink inlet and the lower ball blocks the lower ink outlet, restricting the outflow of ink from the ink storage chamber. This reduces the amount of air entering the ink storage chamber and improves its resistance to negative pressure. This solves the problem in existing double-ended markers where the pressure in the ink storage chamber increases due to the connection between the two ends, causing ink leakage or rapid ink drop. This invention slows down ink drop and prevents ink leakage.

[0032] 2. When writing, ink can flow normally from the writing end (because a certain amount of ink is stored in the ink absorber). After writing continuously and quickly for a certain length, the problem of white showing can be solved by briefly placing the pen horizontally on its side or shaking it. Attached Figure Description

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," "front," "back," and similar expressions used in this document are for illustrative purposes only.

[0039] 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.

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0041] like Figure 1-3 As shown, a double-ended single-pass marker includes a pen barrel 1 and a pen tip (not shown in the figure). The pen barrel 1 is a container-shaped structure with openings at both ends and an ink storage cavity 10 inside. The pen tip 2, which has a hollow through structure, is respectively provided at the openings at both ends of the pen barrel 1.

[0042] One end of the pen tip 2 is provided with an ink control component 3, and the other end is provided with a pen nib;

[0043] An ink absorber 4 for absorbing liquid ink is provided between the pen tip and the ink control component 3;

[0044] The ink control assembly 3 includes an ink control valve body 31 and a ball 32 movably disposed within the ink control valve body 31;

[0045] One end of the ink control valve body 31 is provided with an ink inlet hole 20 that communicates with the ink storage chamber 10, and the other end is provided with an ink outlet hole 30 that contacts the ink absorption body 4.

[0046] When the marker is held upright or at a set angle, under the action of gravity, the upper ball 32 blocks the ink inlet hole 20 of the corresponding ink control valve body 31, and the lower ball 32 blocks the ink outlet hole 30 of the corresponding ink control valve body 31.

[0047] In this embodiment, an ink control assembly 3, consisting of an ink control valve body 31 and a ball 32, is respectively provided at one end of the pen tip 2 near the ink storage chamber 10. When the marker is upright or at a set angle, under the action of gravity, the upper ball 32 blocks the upper ink inlet hole 20, and the lower ball 32 blocks the lower ink outlet hole 30, restricting the flow of ink out of the ink storage chamber 10, reducing the amount of air entering the ink storage chamber 10, and improving the resistance to negative pressure. This solves the problem in the prior art where double-ended markers are prone to ink leakage or rapid ink dripping due to the increased pressure in the ink storage chamber 10 caused by the connection between the two ends, thus slowing down ink dripping and preventing ink leakage.

[0048] In the above structure, when the marker is held upright during writing, the ball 32 will block the holes of the upper and lower ink control valve bodies 31. The writing end can still output ink normally (because the ink absorber 4 stores a certain amount of ink). After writing continuously and quickly for 8 to 10 meters, the ink will become white. At this time, it is necessary to briefly place the marker horizontally or shake it to release the blockage of the ball 32 on the holes of the ink control valve body 31, so that the ink in the ink storage chamber 10 can enter the ink absorber 4 and the pen tip through the ink control component 3 to achieve ink output. Then, it can be used normally again.

[0049] Furthermore, such as Figure 1 , 3 As shown, the ink control valve body 31 includes a valve seat 311 that is sleeved with the pen tip 2;

[0050] The valve seat 311 has a valve cover 33 at the ink inlet side opening and a funnel section 312 with a gradually decreasing inner diameter at the ink outlet side.

[0051] The ink outlet of the funnel section 312 forms an ink outlet hole 30 that contacts the ink absorber 4;

[0052] One end of the valve cover 33 is sealed and engaged with the valve seat 311, and the other end is a funnel end with a gradually decreasing inner diameter.

[0053] The end face of the funnel end is provided with an ink inlet hole 20;

[0054] The ball 32 is movably disposed within the ink control cavity 40 formed between the valve seat 311 and the valve cover 33.

[0055] In this embodiment, during assembly, the ball 32 is first placed inside the valve seat 311, and then the ball 32 is confined within the ink control cavity 40 by the valve cover 33 engaging with the valve seat 311.

[0056] In this embodiment, a limiting rib is provided at the sealing engagement point between the valve seat 311 and the valve cover 33, and a limiting ring is provided at the sealing engagement point between the valve cover 33 and the valve seat 311.

[0057] Furthermore, such as Figure 1 , 3 As shown, a groove 50 is provided in the funnel section 312 where it contacts the sphere 32.

[0058] In this embodiment, the groove 50 creates a gap between the funnel section 312 and the sphere 32, allowing ink to pass through and maintaining a continuous ink supply.

[0059] Furthermore, such as Figure 1 , 2 As shown in Figure 3, the funnel section 312 is provided with an ink guiding section 313 that contacts the ink-absorbing body 4 at the end away from the valve seat 311.

[0060] The ink guiding section 313 is provided with an ink passage hole 60 that connects the ink control cavity 40 and the ink absorber 4.

[0061] The ink passage 60 has a notch 5 at the end that contacts the ink absorber 4.

[0062] In this embodiment, because the ink has tension, the notch 5 is used to puncture the ink flowing out of the ink passage 60, making it easier for the ink to flow into the ink absorber 4 and improving the ink output effect.

[0063] Furthermore, such as Figure 1 , 2 As shown in Figure 3, the ink passage 60 extends to the point where it contacts the sphere 32 inside the funnel section 312.

[0064] In this embodiment, the ink passage 60 creates a gap between the sphere 32 and the funnel section 312 to allow ink to pass through, thus maintaining a continuous ink supply.

[0065] Furthermore, in order to reduce the local resistance of ink flow and improve the ink dispensing effect, the cross-section of the ink passage 60 is polygonal.

[0066] In this embodiment, depending on the type of ink used, the cross-section of the ink passage 60 can be a polygonal structure such as a quadrilateral or a hexagon.

[0067] Furthermore, such as Figure 1 As shown, in order to improve the capillary conduction effect of ink, the ink absorber 4 is a flexible fiber with dense pores, and the ink passage 60 and the pen tip are respectively inserted into the interior of the ink absorber 4; the fiber can be natural fiber or chemical fiber, such as cotton, polyester fiber, etc.

[0068] Furthermore, the sphere 32 is made of stainless steel or ceramic material.

[0069] Furthermore, such as Figure 1 As shown, in order to protect the pen tip, a pen cap 6 is provided on the outside of the pen tip to cover the pen tip, and the pen cap 6 is detachably connected to the pen tip 2 or the pen barrel 1.

[0070] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
