Description

Technical Field

[0001] This utility model relates to the field of stationery technology, and in particular to a split-type water storage device. Background Technology

[0002] The water storage products commonly found on the market typically consist of a water storage shell and a drinking core connected to the water storage shell, used to store and deliver ink in writing instruments.

[0003] Existing water reservoirs have some shortcomings in practical use: First, in terms of negative pressure performance, their negative pressure test values ​​are generally between -10kPa and -15kPa. Although this basically meets the national standard requirement of -10kPa, there are still issues with insufficient stability in extreme environments. Second, some products may experience ink dripping or no ink output during use, affecting the smoothness and reliability of writing. Third, during high and low temperature environment tests, a large amount of ink will flow into the water reservoir, causing contamination of the reservoir's appearance and affecting the product's aesthetics. In addition, when the product is placed vertically for a long time, the titanium dioxide in the ink will gradually deposit around the drinking core, thus hindering the drinking core's ability to absorb ink and further affecting writing performance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a split-type water storage device. This split-type water storage device has a simple structure and high stability in ink output and leak prevention.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A split-type water storage device includes: a water storage shell, an end cap, and a drinking core; a connecting cylinder section is provided at one end of the water storage shell, and a liquid suction element is provided inside the connecting cylinder section; multiple sealing sections are provided on the side of the water storage shell along the axial direction, and a water storage section is formed between adjacent sealing sections; the end cap is at least partially fitted onto the connecting cylinder section; and the drinking core at least partially passes through the water storage shell, the liquid suction element, and the end cap.

[0006] Furthermore, a cover is provided on the front side of the end cap. The cover is arc-shaped and is fixedly connected to the end cap by a support plate. The drinking core is at least partially penetrated by the support plate and the cover.

[0007] Furthermore, the end cap, support plate, and cover are integrally molded structures.

[0008] Furthermore, the front end face of the end cap is provided with a stepped surface surrounding the drinking core.

[0009] Furthermore, the end cap is provided with a limiting block to restrict the movement of the liquid suction component.

[0010] Furthermore, the sealing section is an annular flange structure, and the sealing section in the middle is provided with a notch for connecting the water storage sections at both ends.

[0011] Furthermore, the water storage section is a series of annular groove structures arranged at intervals along the axial direction of the water storage shell.

[0012] Furthermore, the volume of the water storage section increases sequentially from the front end of the water storage shell to the rear.

[0013] Furthermore, the liquid-absorbing component is one of a sponge, porous plastic, or fiber bundle.

[0014] Furthermore, an annular protrusion is provided on the side of the connecting cylinder section, and a groove is provided inside the end cap that can engage with the annular protrusion.

[0015] In the aforementioned split-type water reservoir, the water reservoir shell and the tail cap adopt a two-stage sealing structure. During high and low temperature environment testing, the ink flowing into the water reservoir can be absorbed by the internal sponge and blocked at the second sealing point, thereby maintaining the clean and beautiful appearance of the product. At the same time, the sponge inside the water reservoir can temporarily absorb and store the flowing ink under high and low temperature environments, forming a short-term negative pressure, further suppressing ink outflow and improving the sealing reliability and appearance stability of the product.

Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In addition, to clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The top, bottom, left, right, front, and back sides are shown.

[0019] like Figures 1 to 3 As shown, this application provides a split-type water storage device, which includes: a water storage shell 1, an end cap 2, and a drinking water core 3.

[0020] Specifically, the water storage shell 1 has a connecting cylinder section 11 at one end, and a liquid suction component 4 is provided inside the connecting cylinder section 11; the side of the water storage shell 1 has multiple sealing sections 12 along the axial direction, and a water storage section 13 is formed between adjacent sealing sections 12; the end cap 2 is at least partially fitted on the connecting cylinder section 11; the drinking core 3 is at least partially inserted through the water storage shell 1, the liquid suction component 4 and the end cap 2.

[0021] With the above settings, in high and low temperature environments, the liquid absorption component 4 can absorb and temporarily store the ink after it enters the water storage section 13, forming a negative pressure to reduce liquid outflow. No more ink will flow out at the second sealing section 12, which improves the ink output stability of the water storage device and the aesthetics of the product during use.

[0022] like Figure 1 and Figure 2 As shown, the front side of the end cap 2 is provided with a cover 5. The cover 5 is arc-shaped and is fixedly connected to the end cap 2 by a support plate 6. The drinking core 3 is at least partially penetrated by the support plate 6 and the cover 5. The combined structure of the arc-shaped cover 5 and the support plate 6 can effectively prevent sediment from accumulating near the drinking core 3, avoid blocking the liquid absorption channel, thereby significantly extending the working life of the drinking core 3 and maintaining stable liquid flow and adsorption performance.

[0023] The end cap 2, support plate 6, and cover 5 are integrally molded, which reduces the number of parts and assembly steps, thereby reducing production costs and assembly time.

[0024] The front end of the end cap 2 has a stepped surface 21 surrounding the drinking core 3, thus forming a physical barrier structure that promotes sediment settling on the outside of the stepped surface 21 and prevents it from concentrating in the drinking core 3. The combined use of the stepped surface 21, the arc-shaped cover 5, and the support plate 6 can doubly block sediment from entering the drinking core 3 area, maintaining a stable anti-sedimentation effect even when the product is tilted or when the temperature changes.

[0025] like Figure 3 As shown, the end cap 2 is provided with a limiting block 22 for restricting the movement of the liquid suction component 4. This structure can extend the service life of the liquid suction component 4 and improve the overall sealing effect; at the same time, it reduces problems such as leakage and air resistance caused by the displacement of the liquid suction component 4 when the water reservoir is tilted or impacted.

[0026] like Figure 2 and Figure 3 As shown, the sealing section 12 is an annular flange structure, and a notch 121 for connecting the two water storage sections 13 at its two ends is provided on the sealing section 12 in the middle. The annular flange structure has reliable sealing and is simple to process, which can effectively prevent liquid leakage during the use or transportation of the water storage device; the notch 121 in the middle sealing section 12 is designed to maintain the sealing performance and realize the liquid balance between the water storage sections 13, thereby improving the adaptability of the water storage device under different postures.

[0027] The water storage section 13 consists of several annular grooves spaced apart along the axial direction of the water storage shell. The segmented structure can reduce large-scale liquid sloshing, thereby maintaining stable ink output during product use.

[0028] The volume of the water storage section 13 increases sequentially from the front end to the rear of the water storage shell, which can optimize the flow and distribution of liquid in the water storage tank and improve the continuity and stability of liquid supply.

[0029] The liquid absorption element 4 can be made of sponge, porous plastic, or fiber bundle, allowing for flexible selection in terms of absorption speed, storage capacity, structural stability, and durability to meet different application requirements. The porous material structure not only facilitates liquid adsorption and storage but also delays the entry of sediment into the drinking core 3 area, thereby improving the service life and stability of the drinking core 3.

[0030] like Figure 2 As shown, the connecting cylinder section 11 has an annular protrusion 111 on its side, and the end cap 2 has a groove that engages with the annular protrusion 111. This engagement design allows for quick connection and separation of the end cap 2 from the water storage shell 1, eliminating the need for thread tightening or additional fasteners and improving assembly efficiency. Simultaneously, this structure provides a secure connection while maintaining stable sealing performance to prevent liquid leakage.

[0031] The above description of embodiments of the present invention, through which those skilled in the art are able to implement or use the present invention, will be readily apparent to those skilled in the art. Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novelty disclosed herein.
