Abstract: A direct-liquid writing instrument includes a penholder, an ink feeder and a nib. One end of the penholder is provided with a writing portion, and the other end of the penholder is provided with an ink storage portion. The nib is partially inserted into the writing portion. The direct-liquid writing instrument also includes a first baffle and a second baffle that are spaced apart from each other to form an air barrier layer. The first baffle is in contact with the ink of the ink storage portion, and the second baffle is adjacent the writing portion. Additionally, the first baffle is provided with a first air-guiding channel, and a second air-guiding channel is provided between the second baffle and the ink feeder. The ink feeder passes through the first baffle, the air barrier layer, and the second baffle to deliver the ink to the nib.

Abstract: Disclosed is a direct-liquid writing instrument. Two ends of a penholder (1) are provided with a writing portion (11) and an ink storage portion (12) respectively. A nib (3) is partly inserted into the writing portion (11). A first baffle (41) and a second baffle (42) of an adjusting portion (4) are spaced apart so that an air barrier layer (43) is formed between the two baffles. The first baffle (41) is in contact with the ink (13) of the ink storage portion (12). The second baffle (42) is adjacent to the writing portion (11). An ink feeder (2) passes through the first baffle (41), the air barrier layer (43) and the second baffle (42). The first baffle (41) is provided with a first air-guiding channel (8). A second air-guiding channel (7) is provided between the second baffle (42) and the ink feeder (2). At least one gap is formed between the second air-guiding channel (7) and the ink feeder (2).
