[0034] like Figures 1 to 7 As shown in the illustration, an ink-guiding assembly for a direct-liquid acrylic pen, comprising a pen tip assembly, an ink cartridge assembly, and an ink-guiding core 3, is provided in this embodiment of the present invention. The pen tip assembly is connected to one end of the ink cartridge assembly. The ink cartridge assembly includes an ink cartridge 1 and an regulator 2. The regulator 2 is located inside the ink cartridge 1, and a first through-flow ink channel is formed inside the regulator 2. A second through-flow ink channel is provided inside the pen tip assembly. One end of the ink-guiding core 3 extends into the second ink channel, and the other end passes through the first ink channel and extends into the ink cartridge 1. A movable member 4 is provided inside the ink cartridge 1, and the movable member 4 is movably positioned near one end of the pen tip assembly.

[0035] The ink cartridge 1 is also provided with a limiting member 5, which is located between the movable member 4 and the regulator 2. When the movable member 4 is in the first position, the movable member 4 abuts against the limiting member and restricts the movable member 4 from contacting the water inlet core 3.

[0036] This feature protects the water inlet core from impacts by the moving part by limiting contact between the moving part and the water inlet core, thus extending product lifespan.

[0037] The limiting element may be a cylindrical body surrounding the ink core and extending axially in the direction of the ink core, or at least one extension plate surrounding the ink core and extending axially in the direction of the ink core, or the aforementioned cylindrical body and extension plate combined together, or a barrier plate fixed to the inner wall of the ink cartridge and located above the ink core (here the direction away from the pen tip assembly is defined as upward), etc.

[0038] The movable parts, such as stainless steel beads, blocks, and columns, move freely within the ink cartridge to agitate the ink, prevent it from solidifying, and promote uniform dispensing. One or more movable parts can be provided as needed. In this application, the movable part is specifically a cylindrical stainless steel component.

[0039] The limiting member 5 includes at least two extension plates 51 arranged around the water core 3 and extending along the axial direction of the water core 3.

[0040] Each extension plate can be fixed to the inner wall of the ink cylinder or to the end of the regulator, or it can be movably installed inside the ink cylinder to form an axial sliding fit with the ink cylinder wall.

[0041] The limiting member can comprise several independent extension plates or a cylinder structure formed by connecting several extension plates.

[0042] In this embodiment, two independent extension plates are arranged, and the two extension plates are arranged opposite to the center of the water guide core, so as to ensure the effective contact area of the water guide core and the ink in the ink cartridge and increase the liquid output of the direct liquid pen.

[0043] The fixing plate 52 is provided with a fixing hole 53 penetrating in the axial direction, and the water guide core 3 penetrates the fixing hole 53.

[0044] The end of each extension plate 51 close to the pen head assembly is fixedly connected with the regulator 2, and the fixing plate 52 is fixed relative to the position of the regulator 2.

[0045] The fixing plate can be fixed relative to the regulator in the form of being connected with the regulator through a separate connecting member or in the form of being fixed with the extension plate. In this embodiment, the fixing plate is fixed with the extension plate, and the fixing plate, the extension plate and the regulator can be integrally formed through injection molding or mold combination, thereby improving the processing convenience.

[0046] The fixing plate 52 is fixed between the axial middle parts of the extension plates 51.

[0047] Through the arrangement, the extension plates form a linkage body through the fixing plate, the fixing plate improves the strength of the extension plates, and ensures the ink absorption of the upper and lower spaces of the fixing plate, so that the direct liquid pen has a large liquid output.

[0048] The fixing hole 53 limits the movement of the water guide core 3 away from the pen head assembly.

[0049] Through the arrangement, the fixing hole has a certain positioning effect on the water guide core. The fixing hole can be fixedly connected with the water guide core, or the fixing hole and the pen head assembly can jointly form the axial limiting effect on the water guide core.

[0050] The fixing hole can be tightly fitted with the water guide core, or a limiting ring groove with a size matched with the fixing hole can be arranged at a position of the water guide core, the water guide core is connected with the fixing hole by penetrating the fixing hole and the limiting ring groove, and the axial movement of the water guide core is limited. In this embodiment, the fixing hole is tightly fitted with the water guide core.

[0051] The fixed hole and the pen head assembly together constitute an axial limiting effect on the water guide core. The fixed hole is provided with a small hole section and a large hole section, and the small hole section and the large hole section form a first limiting step. The end of the water guide core is correspondingly provided with a small diameter section and a large diameter section, and the small diameter section and the large diameter section form a second limiting step. The first limiting step and the second limiting step abut to limit the movement of the water guide core away from the pen head assembly. The pen head assembly is connected with the ink cartridge to limit the movement of the water guide core towards the pen head assembly.

[0052] The fixed hole and the pen head assembly together constitute an axial limiting effect on the water guide core. The fixed hole is provided with a small hole section and a large hole section, and the small hole section and the large hole section form a first limiting step. The end of the water guide core is correspondingly provided with a small diameter section and a large diameter section, and the small diameter section and the large diameter section form a second limiting step. The first limiting step and the second limiting step abut to limit the movement of the water guide core away from the pen head assembly. The pen head assembly is connected with the ink cartridge to limit the movement of the water guide core towards the pen head assembly.

[0053] The end of the regulator 2 close to the pen head assembly comprises at least one matching convex ring 202 which is tightly matched with the inner wall of the ink cartridge 1. An axially extending balance air channel 203 is arranged on the matching convex ring 202.

[0054] The pen head assembly has a through air inlet channel. The regulator 2 is provided with a gas return groove 201, and the balance air channel 203 at both ends is respectively communicated with the air inlet channel and the gas return groove 201.

[0055] When the matching convex ring 202 is provided with at least two, the balance air channels 203 of adjacent matching convex rings 202 are arranged staggered.

[0056] In the writing process of the direct liquid type pen, air needs to be introduced to balance the internal and external pressure to discharge ink. In the case of high temperature and large internal pressure, air needs to be discharged to prevent the pen head from leaking ink. Therefore, it is necessary to reasonably set the air inlet and outlet. Through the above setting, the balance air channel, the air inlet channel and the gas return groove constitute a back-and-forth gas return channel, which can prevent a large amount of ink from being discharged and can smoothly return air. The balance air channels of adjacent matching convex rings are arranged staggered, which prolongs the length of the gas return channel. Specifically, in the embodiment, the balance air channels of adjacent matching convex rings are arranged relative to the center of the regulator, which further prolongs the length of the gas return channel.

[0057] In the present application, the gas return groove is specifically provided with a coarse gas return groove and a fine gas return groove.

[0058] The pen head assembly comprises a pen head body 6 and a fixed head 7 connected to one end of the ink cartridge 1.

[0059] The first ink flow channel comprises, from an end far away from the pen head assembly to an end close to the pen head assembly, a central through hole 21 through which the water guide core 3 passes, a fixed hole groove 22 which is shaped to fit the tail end of the pen head body 6 and forms a tight fit, and the end of the water guide core 3 close to the pen head body 6 is tightly fitted with the tail end of the pen head body 6,

[0060] The head end of the pen head body 6 penetrates the fixed head 7, and the fixed head 7 has a through air inlet channel between the pen head body 6 and the regulator 2.

[0061] Through the above arrangement, the tail end of the pen head body is tightly fitted with the fixed hole groove, which can not only seal the end of the regulator to prevent ink leakage, but also limit the movement of the water guide core towards the pen head assembly, thereby strengthening the limiting effect. At the same time, the fixed head forms a through air inlet channel between the pen head body and the regulator, and the center of the pen head assembly is sealed and the ring part is vented, thereby ensuring the sealing and smooth gas inlet and outlet.

[0062] The fixed head 7 is a hollow structure, and a plurality of abutting convex ribs 71 are arranged around the center and abut against the outer periphery of the pen head body 6 and the outer periphery of the regulator 2, and air vent grooves 72 are formed between adjacent abutting convex ribs 71.

[0063] Through the above arrangement, the smooth gas inlet and outlet is ensured, and the stability of the cooperation between the fixed head and the pen head body and the regulator is improved.

[0064] A positioning ring groove 61 is arranged at a middle position of the pen head body 6,

[0065] The abutting convex ribs 71 comprise, from the tail end of the pen head body 6 to the head, a first convex rib part 711 which is fitted with the outer periphery of the end of the regulator 2 close to the pen head assembly, a second convex rib part 712 which is inserted into the positioning ring groove 61 and forms a fixed fit with the pen head body 6 and abuts against the end of the regulator 2, and a third convex rib part 713 which is fitted with the outer periphery of the pen head body 6.

[0066] Through the above arrangement, the stability of the cooperation between the fixed head and the pen head body and the regulator is further improved.

[0067] The above disclosure is only a preferred embodiment of the present application, and of course cannot limit the scope of the present application, so equivalent changes made according to the claims of the present application still fall within the scope of the present application.
