Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing device technology, specifically a device for testing the waterproof performance of diaper pads. Background Technology
[0002] As an essential care product for infants and incontinents, one of the core functions of diaper pads is to prevent urine from seeping through, so as to keep the user's skin dry and the environment clean. Therefore, diaper pads are placed on mattresses or mattresses when babies sleep to prevent them from getting wet with urine.
[0003] After the diaper pads are manufactured, a waterproof test is required to ensure their waterproof performance. Existing technology uses a nozzle to spray water onto the surface of the diaper pad to test its waterproof performance. However, during the test, the fixed nozzle causes the water to flow in a fixed position, making it impossible to comprehensively test the waterproof performance of different areas of the diaper pad.
[0004] Therefore, we propose a device for testing the waterproof performance of diaper pads. Summary of the Invention
[0005] The purpose of this invention is to provide a device for testing the waterproof performance of diaper pads. By using this device, the problem of blind spots in the waterproof testing of diaper pads caused by the fixed nozzle is solved.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for testing the waterproof performance of a diaper pad, comprising a testing box, a driving mechanism at the upper end of the testing box, a waterproof testing mechanism at the inner side of the testing box, and the driving mechanism engaging with the waterproof testing mechanism; The waterproof testing mechanism includes a connecting pipe 1 that runs through the testing box and is rotatably connected to it. Connecting pipe 1 engages with the waterproof testing mechanism. A second connecting pipe 2 is rotatably mounted on the upper end of connecting pipe 1, and its upper end connects to an external water pipe. A hollow disc is rotatably mounted on the other end of the connecting pipe. Multiple nozzles are arranged circumferentially on the lower end of the hollow disc. The nozzles, the hollow disc, and the connecting pipe are internally interconnected. When testing the waterproof performance of the diaper pad, connecting pipe 2 is first connected to the external water pipe, allowing water to flow sequentially through connecting pipe 2, connecting pipe 1, and the hollow disc, finally exiting from the multiple nozzles. The waterproof performance of the diaper pad is tested by spraying water. During the spraying process, the connecting pipe is rotated by the drive mechanism, which in turn drives the cavity disc and multiple nozzles to rotate. This causes the sprayed water to be thrown outward and spread, simulating the dynamic diffusion process of urine in real use. This fully covers the center, edges, and corners of the diaper pad, which are prone to leakage, eliminating blind spots in the test. It can also enhance the impact effect of the water flow with centrifugal force, simulating multi-directional seepage pressure, and more rigorously testing the waterproof performance of the diaper pad. Moreover, the large coverage area of a single spray shortens the test time.
[0007] Preferably, a gear is fixedly installed on the outer wall of the connecting pipe, and the driving mechanism includes a servo motor fixedly connected to the outer wall of the testing box. A gear is fixedly installed on the driving end of the servo motor. The gear is meshed with the gear. During the testing process, the servo motor drives the gear to rotate. Because the gear is meshed with the gear, the gear rotates, which in turn drives the gear to rotate. This ultimately drives the nozzle to rotate rapidly around the axis of the cavity disc, making the trajectory of the water flow unpredictable, thus fully covering the surface of the diaper pad.
[0008] Preferably, a sliding groove is provided on one side of the testing box, and a positioning component is provided on the inner side of the testing box. The positioning component includes a connecting plate, and a sliding rod is symmetrically installed on one side of the connecting plate. The sliding rod is slidably connected to the sliding groove. A spring is fixedly installed on the inner wall of the connecting plate, and a clamping plate is fixedly installed at the lower end of the spring. Before testing, two sides of the diaper pad are placed between the clamping plate and the connecting plate respectively. By using the restoring force of the spring, the clamping plate and the connecting plate are forced to clamp the diaper pad in the middle to prevent it from falling off during the subsequent testing process.
[0009] Preferably, a telescopic rod is provided on the inner side of the spring, and the two ends of the telescopic rod are fixedly connected to the connecting plate and the clamping plate respectively. By setting the telescopic rod, the spring can only undergo elastic deformation in the vertical direction, thereby ensuring that the clamping plate effectively clamps and fixes the diaper pad.
[0010] Preferably, acrylic observation windows are fixedly installed on both sides of the testing box to facilitate real-time observation of the waterproof performance by the testing personnel.
[0011] Preferably, rubber legs are fixedly installed at the four corners of the lower end of the testing box, and a drain pipe is fixedly installed on one side of the testing box. The rubber legs can effectively increase the friction coefficient with the ground and improve stability, while the water during the testing process can be recycled and reused through the drain pipe.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention proposes a device for testing the waterproof performance of diaper pads. When testing the waterproof performance of diaper pads, firstly, connecting pipe two is connected to an external water pipe, allowing water to flow sequentially through connecting pipe two, connecting pipe one, and the hollow disc, finally spraying out from multiple nozzles to spray the diaper pad and test its waterproof performance. During the spraying process, a driving mechanism drives connecting pipe one to rotate, which in turn drives the hollow disc and multiple nozzles to rotate, causing the sprayed water to be thrown outward and diffuse, simulating the dynamic diffusion process of urine in real use. This fully covers the center, edges, and corners of the diaper pad, eliminating blind spots in the test. It also enhances the impact effect of the water flow with centrifugal force, simulating multi-directional seepage pressure, and more rigorously testing the waterproof performance of the diaper pad. Moreover, the large coverage area of a single spray shortens the testing time. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0017] Combination Figure 1 , Figure 3A device for testing the waterproof performance of a diaper pad includes a test box 1, a drive mechanism 2 is provided at the upper end of the test box 1, and a waterproof testing mechanism 3 is provided inside the test box 1. The drive mechanism 2 and the waterproof testing mechanism 3 are engaged and connected. The waterproof testing mechanism 3 includes a connecting pipe 35 that penetrates and rotatably connects to the testing box 1. The connecting pipe 35 is engaged with the waterproof testing mechanism 3. A connecting pipe 31 is rotatably installed at the upper end of the connecting pipe 35. The upper end of the connecting pipe 31 is connected to an external water pipe. A cavity plate 33 is rotatably installed at the other end of the connecting pipe 31. Multiple nozzles 34 are arranged in a circular pattern at the lower end of the cavity plate 33. The nozzles 34, the cavity plate 33, and the connecting pipe 31 are internally connected. When it is necessary to test the waterproof performance of the diaper pad, the connecting pipe 31 is first connected to the external water pipe, so that the water flows sequentially through the connecting pipe 31, the connecting pipe 35, and the cavity plate 31. 3. Finally, water is sprayed from multiple nozzles 34 to test the waterproof performance of the diaper pad. During the spraying process, the drive mechanism 2 drives the connecting pipe 35 to rotate, which in turn drives the cavity plate 33 and multiple nozzles 34 to rotate. This causes the sprayed water to be thrown outward and spread, simulating the dynamic diffusion process of urine in real use. This fully covers the center, edges, and corners of the diaper pad, which are prone to leakage, eliminating blind spots in the test. It can also enhance the impact effect of the water flow with centrifugal force, simulate multi-directional seepage pressure, and more rigorously test the waterproof performance of the diaper pad. Moreover, the large coverage area of a single spray shortens the test time.
[0018] Combination Figure 3 Gear 32 is fixedly installed on the outer wall of the connecting pipe 35. The drive mechanism 2 includes a servo motor 21 fixedly connected to the outer wall of the detection box 1. Gear 22 is fixedly installed on the drive end of the servo motor 21. Gear 22 meshes with gear 32. During the detection process, the servo motor 21 drives gear 22 to rotate. Because gear 22 meshes with gear 32, it drives gear 32 to rotate, which in turn drives the nozzle 34 to rotate rapidly around the axis of the cavity disk 33. This makes the falling trajectory of the water flow unpredictable, thus fully covering the surface of the diaper pad.
[0019] Combination Figure 4-5 The test box 1 has a sliding groove 14 on one side and a positioning component 4 on the inner side of the test box 1. The positioning component 4 includes a connecting plate 41. A sliding rod 42 is symmetrically installed on one side of the connecting plate 41. The sliding rod 42 is slidably connected to the sliding groove 14. A spring 43 is fixedly installed on the inner wall of the connecting plate 41. A clamping plate 44 is fixedly installed at the lower end of the spring 43. Before testing, two sides of the diaper pad are placed between the clamping plate 44 and the connecting plate 41 respectively. By using the restoring force of the spring 43, the clamping plate 44 and the connecting plate 41 are forced to clamp the diaper pad in the middle to prevent it from falling off during the subsequent testing process.
[0020] Combination Figure 4 A telescopic rod 45 is provided on the inner side of the spring 43. The two ends of the telescopic rod 45 are fixedly connected to the connecting plate 41 and the clamping plate 44 respectively. By setting the telescopic rod 45, the spring 43 can only undergo elastic deformation in the vertical direction, thereby ensuring that the clamping plate 44 effectively clamps and fixes the diaper pad.
[0021] Combination Figure 5 Acrylic observation windows 13 are fixedly installed on both sides of the test box 1 to facilitate the real-time observation of the waterproof performance by the testers.
[0022] Combination Figure 5 Rubber support legs 11 are fixedly installed at the four corners of the lower end of the test box 1, and a drain pipe 12 is fixedly installed on one side of the test box 1. The rubber support legs 11 can effectively enhance the friction coefficient with the ground and improve stability, while the water during the test can be recycled and reused through the drain pipe 12.
[0023] The specific working process and principle of this utility model are as follows: When it is necessary to test the waterproof performance of the diaper pad, the connecting pipe 2 31 is first connected to the external water pipe, so that the water flows through the connecting pipe 2 31, the connecting pipe 1 35, and the cavity plate 33 in sequence, and finally sprays out from multiple nozzles 34 to spray the diaper pad to test its waterproof performance. During the spraying process, the driving mechanism 2 can drive the connecting pipe 1 35 to rotate, and the connecting pipe 1 35 drives the cavity plate 33 and multiple nozzles 34 to rotate, so that the sprayed water flow presents an outward throwing and diffusion phenomenon, simulating the dynamic diffusion process of urine in real use, fully covering the center, edges and corners of the diaper pad and other easily leaking areas, eliminating blind spots in the test, and also using centrifugal force to enhance the impact effect of the water flow, simulating multi-directional seepage pressure, and more rigorously testing the waterproof performance of the diaper pad; moreover, the large coverage area of a single spray shortens the test time.
