Abstract

The invention relates to a direct liquid type writing tool which comprises a pen body, a writing element, a water leading core and an ink storage assembly, wherein the ink storage assembly is arranged in the pen body and divides the pen body into an ink supply cavity located on the upper portion and an atmosphere communication cavity located on the lower portion, and the ink storage assembly comprises a first ink storage part and a second ink storage part; the outer wall of the first ink storage part and the inner wall of the pen body are provided with a first air guide flow channel in communication with the atmosphere communication cavity, the inner wall of the second ink storage part and the outer wall of the ink leading core are provided with a second air guide flow channel in communication with the first air guide flow channel, the second ink storage part comprises a second ink storage part and an ink storage base which are connected, and the second ink storage part comprises an ink storage cavity; the ink storage base comprises an ink return device, the ink return device is arranged in the ink storage cavity and comprises an ink return flow channel, and the second air guide flow channel communicates with the ink supply cavity through the ink return flow channel. The ink stored in the ink storage cavity can flow back to the ink supply cavity through the air guide flow channel and the ink return flow channel, so that the ink can be fully recycled, and the phenomenon of ink leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of writing utensils, in particular to a straight liquid writing utensil. Background technique [0002] At present, people have developed various direct-liquid writing instruments, which are provided with an ink supply chamber for storing ink, and the ink in the ink supply chamber is transferred to the nib at the end of the water guide core through the water guide core to realize stable ink supply. Its advantage is that the ink capacity is large, and its disadvantage is that it is prone to ink leakage. [0003] In order to solve the problem of ink leakage, various solutions have been developed. For example, the patent notification number is CN105313536A, which discloses a direct-liquid writing instrument, which includes a pen holder, a water guide core, a nib and an adjustment part. One end of the pen holder is provided with a writing part, and the nib is partially inserted in the writing part. One end is p...
