[0002] A marker pen, also known as a permanent marker, is a colored drawing pen used for writing or drawing. It contains ink and is usually equipped with a cap. It generally has a hard or soft pen tip. Existing marker pens are mainly divided into disposable marker pens and refillable marker pens. Disposable marker pens have a short lifespan, and the ink capsule cannot be replaced after the ink is used up. The disposable marker pen is directly discarded, causing waste. For refillable marker pens, the top cap needs to be opened to inject ink.

[0003] After searching, the existing Chinese patent announcement number is: CN219360701U, which provides a marker pen that is easy to fill with ink. The patent provides a locking hole at the bottom of the push block through the setting of a locking component. After the push block is inserted into the card slot, the locking block can be inserted into the locking hole. The push block can be locked by the locking block, which ensures the stability of the sealing plate and prevents the sealing plug from falling off from the inside of the liquid filling nozzle. Pressing the pressing block inward can push the movable plate, the thrust spring contracts, and the push block is moved upward, so that the locking block can be detached from the inside of the locking hole, which makes it easy to open the sealing plate and improves the convenience of ink filling.

The bottom of the two second connecting blocks 12 are fixedly connected with the tough spring piece 13, which is hook-shaped and tough. The outside of the tough spring piece 13 is fixedly connected with a pressing block 14. Disassembly components are provided on the front and back sides of the outer wall of the pen barrel 1, and the two disassembly components correspond to the two tough spring pieces 13. The left and right sides of the outside of the pen barrel 1 are fixedly connected with a third connecting block 19, and stabilizing holes 20 are provided in the two third connecting blocks 19. A sealing cone 21 is fixedly connected to the bottom of the sealing plate 9. The rubber material improves the sealing effect. The sealing cone 21 is arranged in the liquid injection bucket 5, and a seal 22 is fixedly connected to the top of the sealing plate 9 to improve practicality.

[0033] Reference Figure 4The disassembly component includes a fixing block 15, and the two fixing blocks 15 are fixedly connected to the outer wall of the pen holder 1. A slot 16 is provided on the top of the two fixing blocks 15, and a slot 17 is provided on the outer side of the two fixing blocks 15. The slot 17 is communicated with the slot 16. The pressing block 14 is arranged in the slot 17, and the outer part of the pressing block 14 is slidably connected to the inner wall of the slot 17. The disassembly component can be used to conveniently limit the tough spring piece 13 on the blocking plate 9, so as to facilitate disassembly.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A pen tip 3 is passed through and fixedly connected to the conical block 2, and the top of the pen tip 3 extends into the interior of the pen barrel 1. A pen cap 4 is arranged on the outside of the conical block 2, and the pen cap 4 can protect the pen tip 3. The sealing ring 8 is arranged in the mounting groove 6, and the outside of the sealing ring 8 is slidably connected to the inner wall of the mounting groove 6, which can facilitate the expansion and contraction of the sealing ring 8 in the mounting groove 6. The stabilizing hole 20 corresponds to the stabilizing rod 11, and the outside of the stabilizing rod 11 is slidably connected to the inside of the stabilizing hole 20. The stability of the sealing plate 9 during installation can be improved by inserting the stabilizing rod 11 into the stabilizing hole 20.

Two limit blocks 18 are fixedly connected in the slot 16, and the limit blocks 18 are arranged on both sides of the slot 17, and the limit blocks 18 play a limiting role.

[0035] Working principle: During operation, when the marker pen needs to be refilled with ink, the pressing blocks 14 on both sides of the sealing plate 9 are squeezed by hand to shrink the tough spring piece 13 in the slot 16. The tough spring piece 13 shrinks and the end of the tough spring piece 13 is free from the restriction of the limit block 18, so that the sealing plate 9 can be removed, and then the ink is injected from the injection funnel 5 into the inside of the pen barrel 1. The bucket-shaped injection funnel 5 can be more convenient for ink injection. After the ink injection is completed, the stabilizing rods 11 on the left and right sides of the sealing plate 9 are inserted into the stabilizing holes 20 on both sides of the pen barrel 1. At this time, the sealing cone 21 is inserted into the injection funnel 5, and the tough spring pieces 13 on the front and back sides are inserted into the slot 16 at the top of the fixing block 15. At this time, the U-shaped tough spring piece 13 The pressing block 14 is squeezed and contracted by the limit block 18, and enters the slot 17. When the tough spring piece 13 completely enters the slot 16, the outer end of the tough spring piece 13 is separated from the squeezing of the limit block 18, thereby resetting and stretching in the slot 16, and the front end of the tough spring piece 13 is limited by the limit block 18, so that the tough spring piece 13 is in the slot 16, thereby realizing the installation of the blocking plate 9, and when the blocking plate 9 is installed and lowered, the sealing ring 8 is squeezed, and the spring 7 is compressed and contracted, thereby driving the sealing ring 8 to shrink in the installation groove 6, which can keep the sealing ring 8 and the blocking plate 9 in contact, improve the sealing effect, and cooperate with the sealing cone 21 to make the sealing effect better.
