Liquid gathering anti-dry pen

Abstract

The invention discloses a liquid gathering anti-dry pen, and particularly relates to the field of stationery. The liquid gathering anti-dry pen comprises a pen body, a pen head and an outer cover, anink bag is installed in an inner cavity of the pen body, a pen point and a liquid storage core are installed in the ink bag, the pen point is located above the liquid storage core, and ventilation channels are formed in the outer wall surface of the ink bag and the inner wall of one end of the ink bag; and the bottom end of the ink bag is connected with the pen body through a tail plug, an ink storage cavity is formed in the tail plug, sealing plates are fixedly connected to the two sides of the inner wall of the ink storage cavity, and a valve is arranged at one side of each sealing plate. According to the liquid gathering anti-dry pen, through the arrangement of the ventilation channels and an airtight design structure, a volatile material body can be better protected; and liquid is concentrated at the upper end of the liquid storage core in cooperation with the liquid gathering function of the liquid storage core, so that uneven liquid discharging, color fading or pen point drying are avoided, waste caused by material body waste, drying and the like is reduced, the cost and resource waste are reduced, and a better liquid outlet function is achieved for a material body with highsolid content and high viscosity.

Description

technical field [0001] The invention relates to the technical field of stationery, and more specifically, the invention relates to a liquid-gathering anti-drying pen. Background technique [0002] Because the material of some pens is volatile, it is easy to cause the tip of the pen to dry out, resulting in a poor sense of use and affecting writing. In addition, the previous cotton core structure does not have the function of accumulating liquid, resulting in the color gradually fading during the writing process, and the material The usage rate of the ink is very low, about 60-80%, and the feeling of use is very poor. In this case, how to quickly eliminate the dryness of the nib and make full use of the ink has become an urgent problem to be solved. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a polycondensation anti-drying pen. The problem to be solved by the present in...
