Description

Technical Field

[0001] This utility model relates to the field of writing instrument technology, and in particular to a device for testing the reliability of ink waterproofing. Background Technology

[0002] Because some specialized writing instruments, such as exam pens, have high requirements for waterproof performance, traditional testing methods involve immersing the paper with the writing marks in water after writing on it and observing the results. While this method can simulate waterproof performance in a static state, it doesn't fully simulate real-world conditions. When writing paper is soaked due to flooding or other unforeseen events, water flow can occur, and the paper itself may experience impact forces. For example, in flowing water, the paper fibers may separate after wetting, further affecting the waterproofness of the writing. Therefore, a non-static device is needed to simulate waterproof reliability testing.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0004] In response to the problems mentioned in the background art, this utility model proposes an ink waterproof reliability testing device that simulates ink waterproof testing under non-static conditions, which is closer to the actual application state and improves the testing accuracy.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: In some embodiments of this application, an ink waterproof reliability testing device is provided, comprising: A paper hanging section, which is configured to hang paper; A pumping device is provided, with a distance between the pumping device and the paper hanging part, and the pumping device is configured to spray water onto the paper to wet the ink lines on the paper.

[0006] In some embodiments of this application, the paper hanging part includes a back plate with an opening. The paper is placed on the side of the back plate away from the pumping device, and the water sprayed by the pumping device flows through the opening onto the paper.

[0007] In some embodiments of this application, the back plate is provided with a hook on the side away from the pump pressure device; paper clips are provided on the upper and lower sides of the paper, and the upper paper clip is hung on the hook.

[0008] In some embodiments of this application, the paper is pasted or fixed to the back plate by magnetic snaps.

[0009] In some embodiments of this application, the back plate is provided with a plurality of openings, and a plurality of pump pressure devices are provided, with each of the plurality of openings corresponding to a plurality of pump pressure devices.

[0010] In some embodiments of this application, a first water tank is provided below the back panel, and the first water tank is configured to collect water droplets flowing down from the back panel.

[0011] In some embodiments of this application, the testing apparatus further includes a second water tank configured to supply water to the pumping device.

[0012] In some embodiments of this application, the testing apparatus further includes a water tank configured to collect water droplets flowing from the backplate and to supply water to the pumping device.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are: The ink waterproof reliability testing device disclosed in this application, through its core structural design of a pump and paper hanging unit, innovatively constructs a dynamic water flow erosion testing environment: the pump can compress and spray water to form a water column with specific impact force, directly acting on the ink traces on the paper at a preset distance; simultaneously, the paper is fixed by the hanging unit, and during the water flow erosion process, it can realistically simulate the stress state of paper under water flow impact in actual scenarios, causing the paper fibers to gradually disperse and break due to wetting. This process completely reproduces the dual impact of water flow impact and paper structure changes on ink traces in actual applications, fundamentally solving the technical pain point of the disconnect between traditional static testing and actual application scenarios, making the test results closer to real-world usage conditions, and providing a more accurate basis for verifying the ink waterproof performance of writing instruments.

[0014] The testing device described in this application utilizes the impact force of a water jet generated by a pump to directly act on ink particles adhering to paper fibers. On one hand, the water flow causes the dense structure of the paper fibers to break down and disperse, indirectly weakening the bond between the ink particles and the fibers. On the other hand, the direct impact force of the water jet creates a peeling force on the ink particles, enabling precise testing of the adhesion strength of the ink particles to the fibers. This testing method not only detects the diffusion of ink in a dynamic water environment but also provides a deeper assessment of the strength of the bond between the ink and paper fibers. It achieves comprehensive testing from surface water resistance to deep adhesion reliability, covering key performance dimensions that traditional testing cannot reach, and providing more comprehensive technical feedback for ink formulation optimization and writing instrument quality improvement.

[0015] The core of the testing device in this application consists only of a paper hanging part and a pump device. The structure is simple and does not require a complex mechanical transmission or control system, which reduces the manufacturing and maintenance costs of the equipment. At the same time, the pump device can use common existing equipment such as electric pumps and manual water guns, without the need for customized special parts, which further improves the ease of use and economy of the device.

[0026] In some embodiments of this application, an ink waterproofing reliability testing device is provided, with reference to... Figure 1 and Figure 2 It includes a paper holding section 100 and a pumping device 200. The paper holding section 100 is configured to hold paper 400. There is a distance between the pumping device 200 and the paper holding section 100, and the pumping device 200 is configured to spray water onto the paper 400 to wet the ink lines on the paper 400.

[0027] The pumping device 200 can be an electric pump or a manual pumping device, for example, a water gun. The pumping device 200 sprays a water jet, formed by compressed jetting, onto the paper 400 at a certain distance, rinsing the paper 400. During the rinsing process, the fibers of the paper 400 are gradually wetted and broken down. At this time, the ink lines on the paper 400 will be affected because, as the paper 400 fibers are dispersed by the water jet, the dense structure of the paper 400 fibers is destroyed. The impact force of the water jet will directly exert a force on the ink particles already attached to the paper 400 fibers. Therefore, the adhesion of ink particles to the paper 400 fibers can be tested, and further, the water resistance of the ink can be tested.

[0028] When using this testing device, ink lines are first written on paper 400 using a writing instrument; the paper 400 is then fixed to the paper hanging part 100 with the ink lines facing the pumping device 200; then, water is sprayed onto the paper 400 through the pumping device 200, and the water washes away the ink lines on the paper 400; the water flow is then used to determine the ink waterproof performance of the corresponding writing pen by observing the diffusion of the ink lines.

[0029] Traditional ink waterproofing testing methods only involve statically immersing paper with ink lines in water for observation. This can only simulate an ideal static environment without water flow impact or paper fiber stress and cracking. It cannot fully reproduce the dynamic impact of water flow and the wetting and cracking of paper fibers caused by floods or accidental splashes in actual applications. As a result, the test results deviate greatly from the actual ink waterproofing performance in use, and cannot provide reliable performance verification for writing instruments with high waterproofing requirements, such as exam pens.

[0030] The ink waterproof reliability testing device of this application, through the core structural design of the pump device 200 and the paper hanging part 100, innovatively constructs a dynamic water flow scouring test environment: the pump device 200 can form a water column with specific impact force through compressed jet, which directly acts on the ink traces on the paper 400 at a preset distance; at the same time, the paper 400 is fixed by the hanging part, and during the water flow scouring process, it can realistically simulate the stress state of the paper 400 under the impact of water flow in actual scenarios, causing the paper 400 fibers to gradually disperse and break due to wetting. This process completely reproduces the dual impact of water flow impact and paper 400 structural changes on ink traces in actual applications, fundamentally solving the technical pain point of the disconnect between traditional static testing and actual application scenarios, making the test results closer to real-world usage conditions, and providing a more accurate basis for verifying the ink waterproof performance of writing instruments.

[0031] Traditional static immersion tests can only observe whether the ink dissolves and spreads in a static water environment, failing to address the core of the ink's waterproof performance—the adhesion between ink particles and paper fibers. In practical applications, the reliability of the ink's waterproof performance essentially depends on whether the ink particles can maintain adhesion during the wetting and cracking of paper fibers. If the adhesion is insufficient, even if the waterproof performance is satisfactory under static conditions, the impact of water flow will cause the writing to rub off or become blurred.

[0032] The testing apparatus of this application utilizes the water jet impact force generated by the pump device 200 to directly act on the ink particles adhering to the paper 400 fibers. On one hand, the water flow causes the dense structure of the paper 400 fibers to break down and disperse, indirectly weakening the bonding foundation between the ink particles and the fibers. On the other hand, the direct impact force of the water jet creates a peeling force on the ink particles, enabling precise testing of the adhesion strength of the ink particles to the fibers. This testing method not only detects the diffusion of ink in a dynamic water environment but also deeply evaluates the strength of the bond between the ink and the paper 400 fibers. It achieves comprehensive testing from surface water resistance to deep adhesion reliability, covering key performance dimensions that traditional tests cannot reach, and providing more comprehensive technical feedback for ink formulation optimization and writing instrument quality improvement.

[0033] The core of the testing device in this application only includes a paper hanging part 100 and a pump device 200. The structure is simple and does not require a complex mechanical transmission or control system, which reduces the manufacturing and maintenance costs of the equipment. At the same time, the pump device 200 can use common existing equipment such as electric pumps and manual water guns, without the need for customized special parts, which further improves the ease of use and economy of the device.

[0034] In traditional static immersion tests, water temperature, immersion time, and other conditions are easily affected by the environment, and there is no unified quantitative standard for water flow impact, leading to significant differences in test results between different batches and different personnel, resulting in a lack of repeatability and comparability. The testing device of this application can standardize test conditions by setting and controlling the parameters of the pump pressure device 200 (such as pump pressure, spray distance, and spray time). For example, the water jet impact force can be controlled by adjusting the output pressure of the electric pump, the effective distance can be ensured to be consistent for each test by fixing the distance between the paper hanging part 100 and the pump pressure device 200, and the duration of water flow action can be controlled by setting the spray time. These controllable test parameters can form a unified test standard, allowing the testing of the water resistance performance of different batches and types of writing instrument inks to be conducted under the same conditions, effectively avoiding the interference of environmental factors on the test results and ensuring the repeatability and comparability of the test results.

[0035] In some embodiments of this application, the paper hanging part 100 includes a back plate 110, the back plate 110 is provided with an opening 140, the paper 400 is disposed on the side of the back plate 110 away from the pump pressure device 200, and the water sprayed by the pump pressure device 200 flows through the opening 140 onto the paper 400.

[0036] For example, when this testing device is used in scenarios such as exhibitions, it can be used for fun interactions with consumers. Consumers can use the pump device 200 to spray water into the opening 140 of the back plate 110. The water will reach the paper 400 behind the back plate 110 through the opening 140, thereby washing away the ink lines on the paper 400. Consumers can judge the ink waterproof performance of the corresponding writing pen by observing the diffusion of the ink lines.

[0037] The back plate 110 provides a stable support for the paper 400, preventing wrinkles and shifts in the paper 400 due to uneven force during water flow, and ensuring that the ink lines are always within the area affected by the water flow. At the same time, the openings 140 on the back plate 110 can be designed with specific shapes (such as circles or squares) and sizes according to testing requirements, which can precisely limit the range of water flow and concentrate the water jet on the preset ink line area, avoiding testing errors caused by water flow dispersion.

[0038] This structural design is particularly suitable for scenarios requiring consumer interaction, such as trade shows and product promotions, and possesses strong adaptability to various scenarios. During the interaction, consumers can operate the pump device 200 (such as a manual water gun) to spray water into the opening 140 of the back panel 110. The water flows through the opening 140 and acts on the paper 400 behind the back panel 110. This process increases the fun and participation of the test, allowing consumers to intuitively and personally participate in verifying the water-resistant performance of the ink. Compared to traditional static displays or professional laboratory tests, it is more likely to attract consumer attention and build trust. For example, at the exhibition booths of writing instrument brands, consumers can quickly gain an understanding of the product's water-resistant performance by personally operating the water spray and observing the differences in water resistance of the writing pens from different brands, helping brands achieve more effective product promotion. At the same time, the shielding effect of the back panel 110 prevents the paper 400 from being directly exposed, reducing the probability of the paper 400 being accidentally damaged during the interaction and ensuring the smooth progress of the interactive test.

[0039] In some embodiments of this application, reference is made to Figure 3 The back plate 110 has a hook 130 on the side facing away from the pump device 200. Paper clips 120 are provided on the upper and lower sides of the paper 400. The upper paper clip 120 is hung on the hook 130 to fix the paper 400 on the back plate 110. The lower paper clip 120 serves to add weight, ensuring the paper 400 hangs flat and preventing it from shifting position under the influence of water flow.

[0040] Paper clip 120 is readily available, facilitating the installation of paper 400. The cooperation between paper clip 120 and hook 130 facilitates the replacement of paper 400.

[0041] In other embodiments of this application, the paper 400 is attached to the back plate 110 by adhesive tape.

[0042] In other embodiments of this application, the paper 400 is fixed to the back plate 110 by magnetic snaps.

[0043] In some embodiments of this application, the back plate 110 is provided with a plurality of openings 140, and the pump pressure device 200 is provided with a plurality of openings 140 and a plurality of pump pressure devices 200, with the plurality of openings 140 corresponding to the plurality of pump pressure devices 200.

[0044] Papers 400 with ink lines written on them by different types of writing pens are hung at different openings 140. After being sprayed and washed by the pump device 200, the spread of ink lines on each piece of paper 400 is observed. This allows for a direct comparison of the water-resistant performance of inks from different types of writing pens.

[0045] In some embodiments of this application, the testing apparatus further includes a water tank 300, which is configured to collect water droplets flowing down from the back plate 110 and to supply water to the pump device 200, thereby achieving water recycling and preventing the testing site from getting wet.

[0046] In some embodiments of this application, a first water pool is provided below the back plate 110. The first water pool is configured to collect water droplets flowing down from the back plate 110, so as to realize water recycling and avoid wetting the test site.

[0047] In some embodiments of this application, the testing apparatus further includes a second water tank configured to supply water to the pump pressure device 200, enabling the pump pressure device 200 to be used continuously for a long time.

[0048] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0049] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
