Abstract

The invention discloses an intelligent pen with a low ink warning function. The intelligent pen with the low ink warning function comprises a pen holder and a pen cap, wherein the pen holder and the pen cap are movably connected; a pen point is arranged on the bottom part of the pen holder; an ink storage pipe is arranged above the pen holder; when the pen holder and the pen cap are connected, theink storage pipe is located in the pen cap; and a sensor for detecting the ink content in the ink storage pipe is arranged in the pen cap. According to the intelligent pen with the low ink warning function provided by the invention, a small folded type sensor is integrated in the pen, so that the use condition of ink can be monitored, a warning signal can be sent out when the ink amount is low, auser can be reminded of refilling, and the occurrence of the phenomenon that the normal use is influenced by insufficient ink when the user goes out for use for a short time is avoided.

Description

technical field [0001] The invention relates to a fountain pen, in particular to an intelligent fountain pen with an ink shortage alarm function. Background technique [0002] Pen is a tool for people to write. In ancient times, people used brushes. Later, with the development of science and technology, various ratios appeared. The most commonly used pens on the market include fountain pens, fountain pens, pencils, etc. Although fountain pens are easy to use, the usage rate The highest, but many calligraphy lovers still like to use the pen as a writing tool. The pen is a writing tool commonly used by people and was invented in the early 19th century. The nib is made of metal, and it is smooth and elastic when writing, which is quite smooth. On the mouth of the pen cap or on the surface of the nib, there are obvious trademarks and models. It is also divided into dip pens, fountain pens, and ink bag pens. [0003] There is a potential problem in using the fountain pen, whic...
