Description

Technical Field

[0001] The utility model relates to the technical field of marker pens, in particular to a reliable ink supply structure of a marker pen. Background Art

[0002] As we all know, a marker pen is a special pen that is usually used to mark or write text, diagrams, images, etc. on various surfaces. It has the characteristics of bright colors, good visibility and easy writing, and is widely used in office, education, art and handicrafts.

[0003] The marker pen needs to be refilled with ink after being used for a period of time. When refilling ink, the ink filling cap at the end of the pen barrel needs to be removed, and then ink is injected into the pen tube. The ink is prone to sedimentation or stratification when stored for a long time, and blockage is prone to occur during ink supply, resulting in poor stability and reliability of ink supply.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a reliable ink supply structure for a marker pen, which has the following beneficial effects:

[0017] The reliable ink supply structure of the marker pen is provided with an ink storage box and an ink delivery pump. The ink storage box can continuously and stably provide an appropriate amount of ink to the capillary through the ink delivery pump to ensure smoothness and stability during writing. The design of the delivery pump usually takes into account the fluidity and anti-clogging properties of the ink. By optimizing the delivery path and structure, the possibility of ink clogging during the delivery process is reduced, thereby improving the reliability of ink supply.

[0018] The reliable ink supply structure of the marker pen is equipped with a stirring device, which can effectively prevent the ink from settling or stratifying in the storage box. The regular operation of the stirring device can ensure that the ink is always in a uniform state, thereby ensuring the consistency and stability of the ink supply. By constantly stirring the ink, the risk of the ink surface drying is reduced. At the same time, stirring can also destroy lumps in the ink to prevent them from clogging the delivery pipe, ensuring a reliable and smooth supply of ink. The stirring device can also ensure that the particles or pigments are evenly distributed in the ink.

[0019] The reliable ink supply structure of the marker pen can be used in two ways through the pen top connected by a snap-fit. First, the ink storage box can be installed on the pen tube for a long time, which is convenient for long-term use of the pen tip and uninterrupted ink supply. Second, when the capillary needs to be refilled with ink, the ink storage box is installed on the pen tube through the pen top snap-fit, which can reduce the weight of the pen tube itself. The user can choose any one of the two usage methods according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS
