<p>A whiteboard pen comprises a front penholder (100) and a rear penholder (500) detachably connected with the front penholder (100), wherein, a cavity (501) for containing ink is formed in the rear penholder (500). A pen point (200) protruding from the front penholder (100) is arranged in the front penholder (100). A roll-packed core (300) and a valve (400) are fixedly arranged in the front penholder (100). A through hole is formed in the middle part of the roll-packed core (300), and the pen point (200) is arranged in the through hole. An ink inlet (A) of the valve (400) is positioned in the cavity (501) side, and an ink outlet (B) of the valve (400) is positioned in the roll-packed core side. When the pen point (200) is in a first state, the ink inlet (A) and the ink outlet (B) of the valve (400) are communicated. When the pen point (200) is in a second state, the ink inlet (A) and the ink outlet (B) of the valve (400) are not communicated. As the whiteboard pen can be refilled with ink after the rear penholder is disassembled, the writing duration of the whiteboard pen is increased. In addition, the pen point is fixed by the roll-packed core deformed more slightly than a sponge, so that the leakage in a writing process is not easy to occur.</p> |
