A push-type ink absorber

technical field

The utility model relates to the technical field of daily school supplies, in particular, it provides a push-type ink absorber.

Background technique

Invention patent case CN113752726A A kind of ink absorber for writing implements and writing implements provides a brand-new push-type ink absorber, but when the ink absorber is applied to writing implements, an air cavity area needs to be set, and for the ink absorber with a collar The application of existing pens is very inconvenient, and a relatively complicated structure needs to be set, and the production is very inconvenient, thereby affecting the application of this patent, resulting in slow progress in the actual application of this patent.

According to CN113752726A, a writing tool ink absorber and an experimental device for writing implements, it is found that the ink absorber can independently absorb ink by properly reducing the inner diameter of the installation hole of the water diversion tail of the exhaust pipe fixing body.

How to expand the scope of application of CN113752726A, a writing implement ink absorber and writing implement, and improve the practicability of the patent is a problem faced by the inventor.

The ink absorbers used in existing fountain pens include push-pull ink absorbers and rotary ink absorbers, but these two ink absorbers have small ink capacity and ink breakage, which is due to the small inner diameter of these ink absorbers. , The adsorption area of ink at both ends is large, resulting in ink adsorption at both ends, and an air hollow area appears in the middle. In the middle and late stages of writing, when the ink adsorbed on the front end of the ink absorber is used up, ink breakage may occur.

The problem of ink breakage of these ink absorbers is an urgent problem to be solved in the application of writing instruments.

Contents of the invention

The purpose of this utility model is to provide a push-type ink absorber for the problems existing in the background technology.
