Description

Technical Field

[0001] The invention relates to a water storage container, in particular to a double-column water storage container for a direct liquid painting brush. Background Art

[0002] The structure of a direct liquid painting pen includes an ink cartridge, a water reservoir, a water guide core, a pen tip, etc., wherein the ink is stored in the ink cartridge, one end of the water reservoir contacts the ink and seals the ink with the ink cartridge, the water reservoir has a multi-layer fin structure for adjusting the pressure in the ink cartridge, the axis of the water reservoir is a cylindrical hollow ink channel, a water guide core is arranged in the ink channel, the main body of the water guide core is cylindrical, and both the upper and lower ends are conical structures, the upper part of the water guide core contacts the ink, and the lower part contacts the pen tip. The water guide core guides the ink from the ink cartridge to the pen tip through capillary action, and its upper part should be exposed to the water reservoir and contact with the ink as much as possible to facilitate better ink absorption. Direct liquid painting pens use water-based ink, which has strong fluidity and can provide a smooth and natural writing experience, but is easy to form a sedimentation surface, and the particles after sedimentation are larger than the pores of the water guide core. Therefore, steel balls are generally placed in the ink cartridge of the direct liquid painting pen. Shake the steel balls before use so that the steel balls break the sedimentation surface so that the water guide core can absorb ink smoothly.

[0003] At present, there are two main problems with such water storage and water core. First, the water core is not positioned. After the water core rises, the lower end cannot touch the pen tip, resulting in the inability to write. Second, when the steel ball is shaken, the steel ball will impact the water core, causing damage to the water core. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a double-column water reservoir for a straight liquid painting brush, including fins, ink channels, and a sealing end. The upper part of the ink channel is a conical positioning part with a gradually decreasing cross-section that can match the cone at the end of the water guide core.

[0005] Preferably, the sealing end is provided with a water guide groove, and the water guide groove intersects with the ink channel.

[0006] Preferably, the water diversion groove is a rounded rectangle.

[0007] Preferably, an anti-collision column is provided on the upper portion of the sealing end.

[0008] Preferably, there are 2-4 anti-collision columns.

[0009] Preferably, a circular anti-collision ring is provided on the anti-collision column.

[0010] A direct liquid painting brush comprises the water reservoir mentioned above. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0018] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0019] In the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0020] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0021] In addition, the terms "installed", "set", "provided with", "connected", "connected", and "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components.

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] A double-column water reservoir for a straight liquid painting brush comprises a fin, an ink channel, and a sealing end. The upper part of the ink channel is a conical positioning part, the cross section of which gradually decreases and can match the conical shape of the end of the water guide core. When the water guide core is loaded from the lower part of the water reservoir, its top part contacts the conical shape to limit the upward movement of the water guide core, thereby ensuring that the water guide core stably contacts the pen tip.

[0024] Preferably, the sealing end is provided with a water guide groove, which intersects with the ink channel to guide the ink into the water guide core, thereby increasing the contact area between the water guide core and the ink, ensuring that the water guide core can guide the ink stably and avoiding the ink sedimentation layer from clogging the water guide core.

[0025] Preferably, the water diversion groove is a rounded rectangle, which is convenient for mold opening.

[0026] Preferably, an anti-collision column is provided on the upper part of the sealing end, and the number of the anti-collision columns is 2-4, which are evenly arranged in the circumferential direction. A circular anti-collision ring is provided on the anti-collision column, and the inner diameter of the anti-collision ring is smaller than the diameter of the steel ball, and ensures that the steel ball cannot contact the sealing end, so as to protect the water diversion core from colliding with the steel ball.

[0027] A direct liquid painting brush comprises the water reservoir mentioned above.

[0028] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
