Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of pen, especially a direct liquid writing pen. BACKGROUND
[0002] The direct liquid writing pen adopts scale capillary structure to precisely control ink, and the design enables liquid ink to stably and uniformly flow out of the nib. The pen usually does not need to be pressed for use, and only needs to be gently shaken before use to make the ink more uniform.
[0003] The direct liquid writing pen is easy to be shaken during use or transportation, and therefore needs a positioning structure to fix the wick in the pen body to ensure that the wick and the nib are always connected, so that the wick can guide the ink into the nib. However, the existing direct liquid writing pen usually directly sets a fixed structure on the pen body to fix the wick, that is, the pen body and the fixed structure are integrally formed, which can fix the wick, but also leads to that one pen body can only be fixed with one size of wick, and if different sizes of wick and nib need to be matched, multiple different pen bodies need to be produced, which greatly increases the cost of mold opening. At the same time, the design of the fixed structure and the pen body being integrally formed also makes it necessary to replace the entire pen body when the positioning structure is damaged, which increases the maintenance cost.

[0025] In one embodiment, as shown in Fig. 1, a straight liquid writing pen 10 according to an embodiment of the present application comprises a shell 100, a visible port 110, a pen body 200, a cavity 210, a groove 220, a stirring block 230, a wick 300, a nib 400, a limiting block 500, a separation layer 510, a fixing block 600, a limiting block 700, a locking block 710, a convex ring 720, a rubber sleeve 800, a cap 900, and a color mark 910. Figure 1 and Figure 2As shown, a straight liquid writing pen 10 comprises a shell 100, a pen body 200, a water guide core 300, a nib 400, a flow limiting block 500, a fixing block 600 and a limiting block 700; the pen body 200 is internally provided with a cavity 210, the fixing block 600, the flow limiting block 500 and the nib 400 are sequentially arranged in the cavity 210, and the limiting block 700 is connected with the pen body 200; the fixing block 600 comprises an outer ring portion 610, an inner ring portion 620 and a plurality of connecting ribs 630, and the inner ring portion 620 is located at the inner central position of the outer ring portion 610, one end of each connecting rib 630 is connected with the outer side of the inner ring portion 620, the other end of each connecting rib 630 is connected with the inner side of the outer ring portion 610, the distance between adjacent two connecting ribs 630 is equal, and the outer side of the outer ring portion 610 abuts against the cavity 210 side wall of the pen body 200; one end of the water guide core 300 is fixed in the inner ring portion 620 of the fixing block 600, the other end of the water guide core 300 abuts against the nib 400 after passing through the flow limiting block 500, and the nib 400 is at least partially located outside the cavity 210 through the limiting block 700.
[0026] Specifically, the straight liquid writing pen comprises a whiteboard pen, a marker pen, a liquid chalk pen, a paint pen, a fluorescent pen, an acrylic pen and the like writing pen. By movably arranging the fixing block 600 in the pen body 200, the fixing block 600 is used for fixing the water guide core in the pen body 200, through the above arrangement, the same pen body 200 can be matched with water guide cores of different sizes, thereby reducing the production cost. Meanwhile, the fixing block 600 is composed of the inner ring portion 620, the outer ring portion 610 and a plurality of connecting ribs 630, and there is a gap between adjacent two connecting ribs 630, so that ink can pass through the gap between the connecting ribs 630. By arranging the inner ring portion 620 at the central position of the outer ring portion 610, the water guide core 300 can be fixed at the central position inside the pen body 200, so that the whole water guide core 300 can be in full contact with the ink in the pen body 200, thereby achieving better water guiding effect. Through the separate arrangement of the fixing block 600 and the pen body 200, the same pen body 200 can be matched with water guide cores of different sizes, thereby reducing the production cost.
[0027] In the embodiment, the water guide core 300 is at least partially inserted into the nib 400, so that the water guide core 300 can be in full contact with the nib 400, thereby guiding the ink in the pen body 200 to the nib 400.
[0028] In order to better control the water yield of the ink, in one embodiment, as shown in FIG. 6, the flow limiting block 500 is arranged between the water guide core 300 and the nib 400, so that the flow limiting block 500 can control the water yield of the ink. Figure 2 andFigure 3 As shown in the figure, several layers of separation layers 510 are arranged on the flow limiting block 500, and each separation layer 510 is arranged at equal intervals. Specifically, by arranging several layers of separation layers 510 on the flow limiting block 500, the ink can be effectively buffered, the ink leakage can be prevented, and the stability and balance of ink supply can be ensured.
[0029] In order to fix the pen nib 400 and the flow limiting block 500 with the limiting block 700, in an embodiment, as shown in the figure, Figure 4 and Figure 5 As shown in the figure, the inner side of the limiting block 700 is provided with several locking blocks 710, and each locking block 710 abuts against the flow limiting block 500 and the pen nib 400. Specifically, each locking block 710 can play a good fixing and supporting role, so as to fix the pen nib 400 and the flow limiting block 500 with the limiting block 700. In order to match the shape of the pen nib 400 and the flow limiting block 500, in the present embodiment, the clamping space formed by the protrusion at one end of each locking block 710 matches the shape of the flow limiting block 500, and the clamping space formed by the protrusion at the other end of each locking block 710 matches the shape of the pen nib 400.
[0030] In the present embodiment, as shown in the figure, Figure 5 The spacing between adjacent two locking blocks 710 is equal. Specifically, each locking block 710 is arranged around the limiting block 700. By setting the spacing between adjacent two locking blocks 710 to be equal, each locking block 710 can stably fix the pen nib 400 and the flow limiting block 500 in the middle part of the limiting block 700, while ensuring that the pen nib 400 is supported by each locking block 710 with equal force, thereby preventing the pen nib 400 from deforming during writing.
[0031] In order to make the ink flow better in the pen body, in an embodiment, a stirring block 230 is further arranged in the cavity 210 of the pen body 200. Specifically, the shape of the stirring block 230 is any one of spherical, cylindrical, conical, and irregular. The material of the stirring block 230 is any one of stainless steel, glass, ceramic, and plastic. According to different inks, the stirring block 230 with any one of the above suitable shapes, any one of the above suitable materials, and a suitable size is selected, so that different inks cooperate with different stirring blocks 230 to achieve a best stirring effect. When the straight liquid writing pen 10 is shaken, the stirring block 230 movably abuts against the side of the fixed block 600 away from the water guide core 300. By arranging the stirring block 230 in the cavity 210 of the pen body 200, the stirring block 230 can fully stir the ink in the pen body 200, so that the ink flows better in the pen body 200.
[0032] In order to better utilize the function of the drinking cartridge in guiding the ink, in one embodiment, such as Figure 2 As shown, both ends of the water-guiding core 300 are conical. Specifically, the conical shape of both ends of the water-guiding core 300 increases the contact area with the ink, thereby achieving a better flow guiding effect.
[0033] In order to allow the water-guiding core 300 to make better contact with the pen tip 400, in one embodiment, such as Figure 2 As shown, one end of the pen tip 400 connected to the water guide core 300 is flat, while the other end of the pen tip 400 is conical. Specifically, by making the surface of the pen tip 400 that abuts against the water guide core 300 flat, and by making the surface of the pen tip 400 that abuts against the water guide core 300 relatively soft, it is easier for the water guide core 300 to be inserted into the flat pen tip 400, thereby allowing the water guide core 300 to make full contact with the pen tip 400 and enabling the water guide core 300 to play a better role in guiding the flow.
[0034] In this embodiment, the length of the ink-guiding core 300 inserted into the fixing block 600 can be adjusted, thereby adjusting the length of the ink-guiding core 300 inserted into the pen tip 400. In other words, the contact area between the ink-guiding core 300 and the pen tip 400 is adjustable. Through this setting, the ink flow rate of the pen tip 400 can be controlled, resulting in different writing effects.
[0035] In order to securely connect the limiting block 700 to the pen body 200, in one embodiment, such as Figure 4 As shown, a protruding ring 720 is provided on the outer surface of the end of the limiting block 700 that is inserted into the pen body 200. A groove 220 is provided at a corresponding position on the side wall of the cavity 210 of the pen body 200. When the limiting block 700 is inserted into the pen body 200, the protruding ring 720 is located in the groove 220. Specifically, when the limiting block 700 is inserted into the pen body 200, the protruding ring 720 will be located in the groove 220, thereby improving the stability of the connection between the limiting block 700 and the pen body 200.
[0036] To make the pen grip more comfortable for users, in one embodiment, such as Figure 1 and Figure 2 As shown, the direct-liquid writing pen 10 also includes a rubber sleeve 800, which is disposed on the pen body 200. Specifically, by providing the rubber sleeve 800 on the pen body 200, and by making the rubber sleeve 800 of rubber, which has a certain degree of softness, the user feels more comfortable when holding the rubber sleeve 800 on the direct-liquid writing pen 10.
[0037] To facilitate observation of the remaining ink level in the direct-liquid writing pen 10, in one embodiment, such as... Figure 1 and Figure 2 As shown, a viewing port 110 is provided on the outer casing 100 for observing the amount of ink inside the pen body 200. Specifically, the pen body 200 is made of transparent plastic, and the ink content inside the pen body 200 can be viewed through the viewing port 110 provided on the outer casing 100. This design facilitates the user's observation of the remaining ink level of the direct-liquid writing pen 10.
[0038] In order to distinguish the color of the direct liquid writing pen 10, in one embodiment, such as Figure 1 and Figure 2 As shown, the direct-liquid writing pen 10 also includes a pen cap 900, which is used to cover the pen tip end of the pen body 200. The pen cap 900 has a color mark 910. Specifically, by providing a color mark 910 on the pen cap 900, and the color mark 910 being colored, the color on the color mark 910 is the color of the direct-liquid writing pen 10. This design facilitates user differentiation of the color of the direct-liquid writing pen 10.
