[0024] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.
[0025] like Figures 1 to 5 As shown, this is an embodiment of the present invention. A marker pen includes a pen body 1, a pen tip 2, and an ink core 3. The pen body 1 has an ink chamber 4 inside, which is filled with ink. The pen tip 2 draws ink through the ink core 3. The pen body 1 is connected to a cover 5 for sealing the ink chamber 4. One end of the cover 5 has an ink outlet hole 6 through which the pen tip 2 passes, and the other end has a protruding ink suction head 7 through which the ink core 3 passes. The inner wall of the ink suction head 7 has a raised step 8. The ink core 3 includes a contact section 9 that contacts the pen tip 2, an abutting section 10 that abuts against the step 8, and an extension section 11 that extends into the ink chamber 4.
[0026] The beneficial effects of this design are as follows: the marker pen of this invention has an ink-absorbing head that can stabilize the ink core, that is, the contact section of the ink core abuts against the step on the inner wall of the ink-absorbing head, preventing the ink core from shaking. Furthermore, the ink core extends through the ink-absorbing head into the ink chamber, increasing the contact area between the ink core and the ink. The ink core can absorb more ink, thereby enabling the pen tip to maintain a certain amount of ink and maintain good and stable ink output.
[0027] Furthermore, the inside of the cover 5 is provided with a water-proof cotton 12, and the water-guiding core 3 also includes a through section 13 that penetrates the water-proof cotton 12.
[0028] The beneficial effects of such an arrangement are as follows: by adding the water-blocking cotton outside the water guide core, the leakage of ink from the water guide core can be effectively prevented, and most of the ink in the water guide core can be transmitted to the pen point, further ensuring stable ink output.
[0029] Further arrangement, the inner wall of one end of the cover 5 near the ink outlet hole 6 is provided with a first limiting part 14, and the inner wall of one end near the ink absorbing head 7 is provided with a second limiting part 15, and the water-blocking cotton 12 is abutted and arranged between the first limiting part 14 and the second limiting part 15.
[0030] The beneficial effects of such an arrangement are as follows: by abutting the water-blocking cotton with the first limiting part and the second limiting part, the water-blocking cotton is prevented from shaking, and the stable ink leakage prevention function of the water-blocking cotton is ensured.
[0031] Further arrangement, the inner wall of the ink absorbing head 7 is also provided with a plurality of windows 16 communicating with the ink chamber 4.
[0032] The beneficial effects of such an arrangement are as follows: the ink in the ink chamber flows into the ink absorbing head through the window, further increasing the contact area between the water guide core and the ink.
[0033] Further arrangement, the inner wall of the ink absorbing head 7 is also provided with a plurality of windows 16 communicating with the ink chamber 4.
[0034] The beneficial effects of such an arrangement are as follows: the air inside the cover flows with the air inside the ink chamber through the air vent groove, achieving the effect of air return, so that the water guide core can normally absorb ink even in a negative pressure environment. The depth of the air vent groove is very shallow, which ensures the normal flow of air and prevents the leakage of ink into the cover.
[0035] Further arrangement, the steps 8 are evenly distributed along the circumference of the inner wall of the ink absorbing head 7, and one window 16 and one air vent groove 17 are arranged between every two steps 8.
[0036] The beneficial effects of such an arrangement are as follows: the outer wall of the abutting section is in close contact with the inner wall of the ink absorbing head, the outer wall of the extending section is also in close contact with the inner wall of the step, and the step is arranged alternately with the air vent groove and the window to avoid conflict, which has the advantages of exquisite structure and convenient production and manufacturing.
[0037] Further arrangement, the inner wall of the ink absorbing head 7 is also provided with a plurality of windows 16 communicating with the ink chamber 4.
[0038] The beneficial effects of the arrangement are as follows: the ink in the gap between the ink absorbing head and the water guiding core is guided to the water guiding core by the water guiding surface, which helps the water guiding core to absorb the ink, and prevents the ink from remaining in the gap, thereby avoiding waste.
[0039] Further, the two ends of the pen body 1 are respectively provided with a cover 5 and a water guiding core 3, and the pen head 2 is also provided with two, i.e., a thick pen head 19 and a thin pen head 20, one of the covers 5 is connected with the thick pen head 19, and the other cover 5 is connected with the thin pen head 20, and the two ends of the pen body 1 are respectively provided with a pen cover 21.
[0040] The beneficial effects of the arrangement are as follows: the ink in the gap between the ink absorbing head and the water guiding core is guided to the water guiding core by the water guiding surface, which helps the water guiding core to absorb the ink, and prevents the ink from remaining in the gap, thereby avoiding waste.
[0041] The above disclosure is only the preferred embodiment of the utility model, and of course cannot limit the scope of the utility model, so the equivalent changes made according to the utility model claim still belong to the scope covered by the utility model.
