Direct-liquid type teaching writing pen

Abstract

The invention discloses a direct-liquid type teaching writing pen for solving the problem of complex structure in the prior art. The direct-liquid type teaching writing pen comprises a pen holder, wherein the pen holder consists of an ink cylinder with a downward opening, a sponge fixed cylinder with a downward opening and a pen point with openings in two ends. Through a sealing structural design of a thread joint, the direct-liquid type teaching writing pen can be recycled; and the writing pen only consists of several parts, so that the structure is simple, the fittings are simplified, the manual assembly speed is largely quickened, the production cost and the labor cost are saved, and high efficiency and energy conservation are realized.

Description

technical field [0001] The invention relates to a straight liquid teaching writing pen. Background technique [0002] Existing commonly used writing pens such as highlighters, markers, blackboard pens and a series of whiteboard pens are mostly disposable. There is an ink-absorbing cotton core in the pen holder. The ink penetrates the nib for writing. Its shortcoming is that the amount of ink absorbed by the cotton core is small. With the use of whiteboard pens, the amount of ink in the cotton core will gradually decrease, and the speed of ink seepage will also slow down, which will affect the writing effect. [0003] On the other hand, most of these whiteboard markers are complex in structure, and the manufacturing cost is relatively high, so it is difficult to be popularized and used on a large scale. Contents of the invention [0004] In view of the above problems, the present invention provides a reusable and convenient writing straight liquid teaching writing pen. ...
