Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 A multiple sealing structure of a whiteboard pen, comprising a pen holder 1, a pen cap 2 is arranged at one end of the pen holder 1, a sealing cover 3 is arranged at the other end of the pen holder 1, pressing blocks 4 are arranged on both sides of one end of the pen holder 1, an ink tank 5 is arranged on one side inside the pen holder 1, an ink guide rod 9 is arranged inside the pen holder 1, a refill 10 is arranged on the pen holder 1, one end of the ink guide rod 9 is located in the ink tank 5, and the other end of the ink guide rod 9 is connected to the refill 10, an ink filling port is arranged at one end of the ink tank 5, a sealing block 6 is arranged at one end of the ink filling port, the sealing block 6 is threadedly connected to the inner wall of the pen holder 1, a handle 7 is arranged on one side of the sealing block 6, and card blocks are arranged at both ends of one end of the sealing cover 3 11. Slots 12 are provided at both ends of one side of the pen barrel 1, one end of the block 11 is located inside the slot 12, mounting slots 13 are provided inside both ends of one side of the pen barrel 1, a connecting rod 14 is provided inside the mounting slot 13, a limiting plate 16 is provided at one end of the connecting rod 14, a spring 15 is provided on the connecting rod 14, one end of the spring 15 is against the limiting plate 16, the other end of the spring 15 is against the inner wall of the mounting slot 13, the other end of the connecting rod 14 is located inside the slot 12, one end of the pressing block 4 is connected to the limiting plate 16, the block 11 is made of elastic material, one end of the block 11 is a slope structure, and one end of the sealing block 6 is made of rubber.
[0023] In actual use of the above structure, firstly, the ink guide rod 9 is set so that the ink guide rod 9 absorbs ink from the ink tank 5 and conducts the ink to the refill 10, and finally flows to the paper during the writing process. Since the setting of the ink guide rod 9 plays a certain buffering role, the ink in the ink tank 5 can flow to the refill 10 more gently, avoiding the refill 10 from discharging ink too quickly, thereby increasing the ink usage time. When the ink in the ink tank 5 is used up, the pressing block 4 is manually squeezed, and the pressing block 4 drives the limiting plate 16, so that the limiting plate 16 squeezes the spring 15 in the mounting groove 13 and pushes the connecting rod 14 , and one end of the connecting rod 14 will push out the card block 11 in the card slot 12, so that the sealing cover 3 can be directly removed from the pen body 1, and then the handle 7 is rotated to make the handle 7 drive the sealing block 6 to rotate, and then the sealing block 6 is withdrawn from the pen body 1, so that new ink is injected into the ink tank 5 through the ink filling port, and then the sealing block 6 is rotated to the ink filling port again to seal the ink filling port, and then the card block 11 of the sealing cover 3 is pushed into the pen body 1, so that the card block 11 is just stuck in the card slot 12, and the sealing cover 3 is installed, which has a double sealing effect and allows the whiteboard pen to be reused.
[0024] In this embodiment, a sealing gasket 8 is provided at one end of the inner part of the pen body 1, and one side of the sealing block 6 is against the sealing gasket 8. The sealing gasket 8 is made of elastic rubber material to further improve the sealing performance of the sealing block 6 after installation.
[0025] In this embodiment, a sealing cavity 17 is provided on one side of the interior of the pen cap 2, and one end of the pen core 10 is located inside the sealing cavity 17. The provision of the sealing cavity 17 can improve the sealing of the pen core 10 and prevent the pen core 10 from drying out.
[0026] In this embodiment, the pressing block 4 is fixedly connected to the limiting plate 16 , and an anti-skid pattern is provided on the surface of one end of the pressing block 4 , thereby improving the anti-skid property of the pressing block 4 .
