Description

Technical Field

[0001] This utility model belongs to the field of stationery technology, and in particular relates to a refillable whiteboard marker. Background Technology

[0002] Whiteboard markers are a type of stationery, named for their use in writing on smooth whiteboards. They are filled with ink, which is a combination of pigment and alcohol. When the ink is written on a whiteboard, the writing can be easily erased because the alcohol is volatile. A whiteboard marker consists of three parts: the pen body, the pen cap, and the ink.

[0003] A Chinese patent application (or patent) with publication number CN203611589U discloses a whiteboard marker, including a front pen barrel and a rear pen barrel detachably connected to the front pen barrel. The rear pen barrel contains an ink-filled cavity, and the front pen barrel has a pen tip protruding from it. A core and a valve are fixed inside the front pen barrel. A through hole is provided in the center of the core, and the pen tip is placed within the through hole. The ink inlet of the valve is located on the cavity side, and the ink outlet of the valve is located on the core side. When the pen tip is in a first state, the ink inlet and outlet of the valve are connected; when the pen tip is in a second state, the ink inlet and outlet of the valve are not connected. Because the whiteboard marker in this embodiment can be detached from the rear pen barrel and refilled with ink, the writing length of the whiteboard marker is extended. Furthermore, since the pen tip is fixed by the core, which deforms less than a sponge, leakage is less likely to occur during writing.

[0004] The aforementioned whiteboard marker has a front and a rear barrel, with the rear barrel threaded to the end of the front barrel. To refill ink, the rear barrel must be removed, and ink poured into it. However, because the front barrel also has internal space, filling only the rear barrel results in a small amount of ink being poured in. Furthermore, ink leakage is a common problem during the filling and reassembly of the front and rear barrels. While the rear barrel is designed for storing and refilling ink, allowing for continuous use, the nib is a consumable part. Prolonged use can damage the nib, requiring replacement. Since the nib is embedded in the front barrel, it is difficult to remove, and holding the nib during removal causes ink to stain the user's hands, further hindering nib replacement. Therefore, we provide a refillable whiteboard marker to solve these problems. Utility Model Content
