[0026] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in further detail below in combination with the drawings.
[0027] It should be noted that all the expressions of "first" and "second" in the embodiments of the utility model are used to distinguish two same name different entities or different parameters, and the "first" and "second" are only used for the convenience of expression, and should not be understood as the limitation of the embodiments of the utility model, and the subsequent embodiments will not be described one by one.
[0028] The direction and position terms mentioned in the utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only the direction or position of the drawing. Therefore, the direction and position terms used are used to explain and understand the utility model, and are not limited to the protection scope of the utility model.
[0029] A marker pen, such as Figure 1As shown, it comprises a pen barrel 1, an ink outlet 2, a pen head sleeve 3 and a liquid seal 4 connected to the tail end of the pen head sleeve 3, the pen barrel 1 is sleeved outside the pen head sleeve 3 and forms an ink storage cavity A with the liquid seal 4, the liquid seal 4 and the pen head sleeve 3 form an ink outlet cavity, and the liquid seal 4 is provided with a through hole 401 communicating the ink storage cavity A and the ink outlet cavity; the ink outlet 2 is provided with a pen nib 201 extending out of the pen head sleeve 3 and a water guide core located in the pen head sleeve 3, the water guide core extends into the through hole 401, the ink in the ink storage cavity A is absorbed by the water guide core through the through hole 401 and is guided to the pen nib 201, and is taken out by the pen nib 201 for writing.
[0030] As shown in the drawings, Figure 2 The pen head sleeve 3 is provided with a storage cotton core 5 sleeved outside the water guide core, and a transition cavity B is formed between the central hole of the storage cotton core 5 and the outer wall of the water guide core; the central hole of the storage cotton core 5 is gaplessly matched with the water guide core at the end part close to the pen nib, and the water guide core is gaplessly matched with the through hole 401. In this way, the transition cavity B between the storage cotton core 5 and the outer wall of the water guide core is closed, the excess ink of the water guide core seeps into the transition cavity B, and the ink in the transition cavity B can be absorbed by the storage cotton core 5, avoiding excessive ink of the water guide core from leaking, and at the same time, when the pen nib 201 needs more ink for writing or drawing, the water guide core continuously supplies ink to the pen nib 201, and at the same time, the transition cavity B and the storage cotton core 5 quickly supplement ink to the middle part of the water guide core, improving the ink supply efficiency of the water guide core and avoiding insufficient ink of the pen nib 201.
[0031] The pen nib 201 and the water guide core can be separate or integrally connected. The separate pen nib 201 and water guide core need to be abutted and connected to ensure the communication of the ink supply and delivery channel, and need to avoid separation of the two when the pen is transported or falls and vibrates. The integrally connected pen nib 201 and water guide core can ensure the communication of the ink supply and delivery channel between the two.
[0032] Further, as shown in the drawings, Figure 4 The inner wall of the pen head sleeve 3 is provided with a plurality of first limiting edges 301 spaced apart and close to the pen nib. The first limiting edges 301 are tightly matched with the outer periphery of the water guide core. By tightly matching the first limiting edges 301 with the outer periphery of the water guide core, axial movement of the integrated pen nib 201 and water guide core can be avoided when the pen is transported, falls and vibrates.
[0033] Further, as shown in the drawings, Figure 3 The pen nib 201 and the water guide core are provided with a first abutting step 204 at the transition of the outer periphery, and the first abutting step 204 abuts the end part of the first limiting edge 301. It can further avoid the inward movement of the integrated pen nib 201 and water guide core when the pen is transported, falls and vibrates.
[0034] As shown in the drawings, Figure 3As shown, the water guide core includes a first water guide part 202 with a larger outer diameter and a second water guide part 203 with a smaller outer diameter, the nib 201, the first water guide part 202, and the second water guide part 203 are connected in sequence, the central hole of the ink storage cotton core 5 is adapted to the outer diameter of the first water guide part 202, so that the part of the central hole of the ink storage cotton core 5 close to the end of the nib is gaplessly matched with the outer periphery of the first water guide part 202 and a transition cavity B is formed between the first water guide part 202 and the second water guide part 203; the second water guide part 203 extends into the through hole 401 and is tightly matched with the through hole 401.
[0035] Further, as shown in Figure 5 , Figure 6 , the liquid seal 4 has a central column 403 and a matching ring 402 sleeved on the outer periphery of the central column 403, the matching ring 402 is fixedly connected with the inner wall of the pen head sleeve 3, the central column 403 is hollowly arranged to form the through hole 401, the end of the central column 403 close to the nib is protruded relative to the matching ring 402, the central column 403 is inserted into the central hole of the ink storage cotton core 5 and is adapted to the central hole of the ink storage cotton core 5, and the two ends of the ink storage cotton core 5 abut against the matching ring 402 and the inner wall of the pen head sleeve 3 respectively. When the pen is transported or dropped and vibrates, the ink storage cotton core 5 is prevented from moving, the space change of the transition cavity B is affected, and if the space of the transition cavity B changes, the ink distribution will be uneven and the probability of ink leakage will be increased.
[0036] As shown in Figure 4 , the pen head sleeve 3 is internally provided with a plurality of second limiting edges 302 which are spacedly distributed, and the end of the ink storage cotton core 5 away from the matching ring 402 abuts against the second limiting edge 302.
[0037] Further, the pen head sleeve 3 is internally provided with a plurality of third limiting edges 303 which are spacedly distributed, and the third limiting edge 303 is tightly matched with the outer peripheral wall of the ink storage cotton core 5.
[0038] As shown in Figure 3 , the outer peripheral wall of the water guide core is provided with an abutting step 204 away from the end of the nib, and the abutting step 204 abuts against the end of the central column 403 close to the nib. The integrated nib 201 and water guide core can be further prevented from moving inward when the pen is transported or dropped and vibrates.
[0039] The inner diameter of the matching ring 402 is greater than the outer diameter of the central column 403. In this way, a cavity can be formed between the matching ring 402 and the central column 403, and the excess ink absorbed by the ink storage cotton core 5 can be stored in the cavity between the matching ring 402 and the central column 403.
[0040] The nib 201 is a soft head imitating a brush.
[0041] The mark pen of the embodiment can be used for the mark pen adopting the ink mixed by the powdered pigment and the liquid solvent, the writing and drawing color effect is better, and the ink is smooth and does not leak, the soft head of the brush pen can realize the writing and drawing function of the thin line and the thick line at the same time, and the ink output structure of the embodiment can also well complete the self-adaptive adjustment of the ink output amount of the thin line and the thick line. For the ink mixed by the powdered pigment and the liquid solvent, the powdered pigment needs to be stirred before use to be uniformly dispersed, and the stirring rod needs to be arranged in the ink storage cavity A.
[0042] The above disclosed is only the preferred embodiment of the utility model, of course, cannot with this to limit the utility model right scope, therefore the equivalent change made by the utility model claim still belongs to the range covered by the utility model.
