[0045] Embodiment 1

[0046] See also Figures 1 to 6 The fabric waterproof performance testing device provided by the embodiment of the present invention comprises a transparent housing 1, a fixing component 2, a spraying component 3 and a control component 4. A display cavity 11 is formed inside the transparent housing 1; the fixing component 2 is arranged in the display cavity 11, and the fixing component 2 is detachably connected to the fabric 100 to be tested, and is used to fix the fabric 100 to be tested; the spraying component 3 is arranged in the display cavity 11, and the spraying component 3 is used to spray water to the fabric 100 to be tested; the control component 4 is connected to the spraying component 3 by signal, and the control component 4 can generate a control instruction to adjust the spraying parameters of the spraying component 3, wherein the spraying parameters include the spraying mode and the spraying time.

[0047] The fabric waterproof performance test device proposed by the present invention adopts a transparent shell 1 to form a display chamber 11, so that the observer can clearly and intuitively observe the waterproof performance of the fabric 100 to be tested during the test. The fixing component 2 is convenient for fixing the fabric 100 to be tested of different sizes and shapes, which improves the versatility and applicability of the device and can meet the testing requirements of various fabrics. The setting of the spray component 3 can simulate the real water spraying situation and more realistically test the waterproof performance of the fabric. And the control component 4 can adjust the spray parameters to achieve the test of different degrees of waterproof performance, so as to comprehensively and accurately evaluate the waterproof effect of the fabric under various conditions. Through the highly visualized test process, the observer can directly experience the waterproof effect of the fabric. This intuitive display method can deepen the observer's understanding of the waterproof performance of the product compared with the traditional static display or text description. With the help of the actual test link, the observer can personally experience the waterproof performance of the product, thereby eliminating doubts about the product performance. Compared with simple advertising or text description, it can win the trust of the observer and thus enhance the desire to buy.

[0048] The specific structure of the fabric waterproof performance testing device is described below.

[0049] The transparent housing 1 is made of high-strength acrylic material and is cylindrical in shape. The thickness of the transparent housing 1 is greater than or equal to 5 mm, so that it has good pressure resistance and wear resistance, ensuring that it will not be damaged by water pressure or accidental collision during the test.

[0050] An openable transparent door is arranged on the front of the transparent housing 1, and the transparent door is connected to the transparent housing 1 through a hinge. A magnetic sealing device is installed on the edge of the transparent door to ensure the sealing performance in the closed state and prevent water leakage. In addition, a layer of rubber sealing strip is wrapped around the edge of the transparent door to further enhance the sealing effect.

[0051] In other embodiments, the transparent housing 1 may also be made of glass, colored glaze or other materials, and its overall shape may also be a rectangular parallelepiped, a sphere or the like, and its material and shape are not limited herein.

[0052] In order to improve the observation effect, an anti-fog coating is provided on the inner wall of the transparent housing 1. The anti-fog coating can effectively prevent the inner wall from fogging due to the temperature difference or humidity difference between the inside and the outside during the test, ensuring that the observer can always clearly see the waterproof test of the fabric 100 to be tested in the display cavity 11, and the observation and judgment of the test process and results will not be affected by the fog, thereby improving the accuracy and reliability of the test.

[0053] Specifically, the anti-fog coating may be a nano-silicon dioxide coating, a fluorine-containing polymer coating, or a hydrophilic polymer coating, etc., which is not limited here.

[0054] The fixing assembly 2 is used to achieve the fixing effect of the fabric to be tested 100. Specifically, the fixing assembly 2 includes a plurality of adjustment clamps 21, which are arranged at intervals along the height direction of the display chamber 11, and the adjustment clamps 21 can clamp the fabric to be tested 100. The plurality of adjustment clamps 21 arranged at intervals along the height direction of the display chamber 11 are provided, so that the fabric to be tested 100 can be fixed at multiple points, ensuring that the fabric to be tested 100 maintains a stable position during the spray test, and will not be displaced or deformed due to the impact of the water flow, thereby ensuring the accuracy and reliability of the test results.

[0055] When fixing the fabric, the observer can adjust the position and clamping force of the three adjustment clamps 21 according to the size of the fabric and the test requirements. For example, for a larger fabric, the three clamps can be clamped at the upper, middle and lower positions of the fabric respectively; for a smaller fabric, only the upper and lower clamps can be used for fixing.

[0056] The spray assembly 3 is arranged in the transparent housing 1 to achieve the spray effect. Specifically, the spray assembly 3 includes a water tank 31, a water pump 32, a water flow pipe 33 and a spray head 34. The water tank 31 is used to store water. The water pump 32 is connected to the water tank 31. One end of the water flow pipe 33 is connected to the water pump 32, and the other end is connected to the spray head 34. The water pump 32 is used to pump the water flow in the water tank 31 to the spray head 34 through the water flow pipe 33, and spray it from the spray head 34 to the fabric 100 to be tested. The setting of the water tank 31 can store enough water to ensure that the test process will not be interrupted due to insufficient water, thereby ensuring the continuity and stability of the test. The water pump 32 can provide stable power to effectively transport the water in the water tank 31 to the spray head 34, thereby ensuring that the spray head 34 has enough water pressure and water volume for spraying, so as to simulate water flow conditions of various intensities and comprehensively and accurately test the waterproof performance of the fabric. The water pipe 33 provides a stable channel for the transmission of water flow, reduces the possibility of water flow leakage and pressure loss, and ensures that the water flow can be smoothly transported from the water pump 32 to the spray head 34. The setting of the spray head 34 enables the water flow to be evenly sprayed on the fabric 100 to be tested, avoiding the situation of inaccurate local testing, and improving the reliability and accuracy of the test results.

[0057] The water pump 32 is an existing micro high-pressure pump, which is an existing device in the art. Its working principle and specific structure are not described in detail here.

[0058] Specifically, the spray assembly 3 further includes a water collecting tank 35, which is disposed at the bottom of the display chamber 11 and is connected to the water tank 31. The water flow sprayed by the spray head 34 can flow back to the water tank 31 through the water collecting tank 35. The water collecting tank 35 is located at the bottom of the display chamber 11, so that the water flow can be collected in the water collecting tank 35 under the action of gravity, effectively collecting the water flow sprayed by the spray head 34, preventing the water flow from flowing around in the display chamber 11, keeping the test environment clean and dry, reducing equipment damage and safety hazards that may be caused by water accumulation, and realizing the recycling of water resources, saving water resources, protecting the environment and reducing test costs.

[0059] More specifically, a guide plate is provided on the water collection tank 35. One end of the guide plate is connected to the inner wall of the water collection tank 35, and the other end is connected to the bottom of the transparent housing 1, so that the water flows rapidly along the inclined direction of the guide plate, effectively guiding the water flow to the water collection tank 35 and finally backflowing to the water tank 31, avoiding silting or poor backflow of the water flow in the transparent housing 1.

[0060] Specifically, the spray head 34 is arranged at the top of the display chamber 11, and the spray head 34 extends in a ring shape. A plurality of spray holes are arranged along the circumference of the spray head 34, and the spray holes face downwardly toward the fabric 100 to be tested, and water can be sprayed out from the spray holes. The spray head 34 is located at the top, so that the water can be sprayed evenly from top to bottom on the fabric 100 to be tested, simulating real rainfall conditions, and more comprehensively and accurately testing the waterproof performance of the fabric, avoiding the occurrence of test dead corners or uneven spraying that leads to deviations in the test results. The design of the ring-shaped extension increases the coverage area of ​​the spray, and can simultaneously perform spray tests on a larger area of ​​the fabric 100 to be tested, thereby improving the test efficiency. The plurality of spray holes are distributed along the circumference, which ensures the uniform spraying of the water flow, making the spray pressure and water volume of the fabric more uniform and consistent, and further improving the reliability and accuracy of the test results.

[0061] Furthermore, the spray head 34 is rotatably connected to the display chamber 11, and the spraying parameters also include a spraying angle. The control component 4 can control the rotation of the spray head 34 to adjust the spraying angle, so that the test device can simulate more diverse and realistic water flow impact conditions.

[0062] For example, by adjusting the angle of the spray head 34, it is possible to simulate inclined rain, changes in the angle of rain caused by wind, etc., and more comprehensively test the waterproof performance of the fabric under the impact of water flow at different angles. By adjusting the spray angle, it is possible to more accurately find the possible waterproof weaknesses of the fabric at a specific angle, providing more targeted information for product optimization and improvement. The flexibility and adaptability of the test are increased, and the waterproof performance test requirements of different types of fabrics and different usage scenarios can be met.

[0063] Specifically, a rotatable support bracket is provided at the top of the display chamber 11, and the spray head 34 is mounted on the support bracket. The support bracket is rotated by a motor drive, and the motor is connected to the control component 4 by signal. The motor adopts a high-precision stepper motor, which can achieve precise angle control. Different spray angle options are preset in the control component 4, such as 0 degrees, 30 degrees, 45 degrees, 60 degrees and 90 degrees.

[0064] When the user selects a spray angle through the control component 4, the control component 4 sends a corresponding command signal to the motor. After receiving the signal, the motor drives the bracket to rotate according to the set rotation speed and angle, thereby adjusting the angle of the spray head 34.

[0065] In order to ensure the stability and accuracy of the rotation, a ball bearing is provided at the connection between the support bracket and the top of the display cavity 11 to reduce friction and wear.

[0066] At the same time, a reducer is installed between the motor and the supporting bracket to ensure the smooth and precise rotation process.

[0067] It is worth noting that the water flow conduit 33 adopts a retractable bellows to accommodate the position adjustment of the sprinkler head 34 .

[0068] In addition, the spray modes include light rain mode, heavy rain mode and rainstorm mode. The water pressure and water flow rate of the spray component 3 are different in different spray modes. The control component 4 can control the spray component 3 to apply any spray mode. It can fully simulate rainfall conditions of different intensities, making the fabric waterproof performance test closer to the actual use scenario. The water pressure and water flow rate of the spray component 3 in different modes are different, which can accurately test the waterproof ability of the fabric under various severe weather conditions, providing observers with more valuable reference information.

[0069] It is understandable that the specific parameters of the water pressure and water flow rate for spraying in different modes are adaptively adjusted according to actual needs and are not limited here.

[0070] Regarding the control component 4, specifically, the control component 4 includes a control panel 41 and a control button 42. The control panel 41 is used for the observer to input control instructions to adjust the spray parameters of the spray component 3, and the control button 42 can control the spray component 3 to switch between the start state, the pause state and the end state.

[0071] Specifically, the control panel 41 has an operation interface. On the operation interface, the observer can input control instructions by touching and selecting different options. For example, the spray time can be adjusted through the slider, ranging from 1 minute to 30 minutes; the spray mode can be selected through the drop-down menu, including light rain mode, heavy rain mode and rainstorm mode; the spray angle can be set through the digital input box, and the angle range is 0 degrees to 180 degrees. The control button 42 is a physical button. Pressing the button once is "start", and after pressing, the spray component 3 starts to work according to the preset parameters; pressing twice is "pause", and after pressing, the spray component 3 temporarily stops spraying water, and short pressing again can continue to work; long pressing for three seconds is "stop", and after pressing, the spray component 3 completely stops working and the system is reset.

[0072] In the actual test, the observer first sets the spray parameters on the control panel 41, for example, selects the heavy rain mode, the spray time is 10 minutes, and the spray angle is 45 degrees, and then short presses the control button 42 once to start the test. If it is necessary to temporarily observe the fabric condition during the test, short press the control button 42 twice to pause, and short press once to continue after the processing is completed. When the test is completed or an abnormal situation occurs, long press the control button 42 for three seconds to end the test.

[0073] In order to facilitate the observer to clearly observe the situation in the display chamber 11, a lighting assembly 5 is provided in the display chamber 11. The lighting assembly 5 can provide sufficient and uniform light, so that during the test process, both the details of the fabric 100 to be tested and the spraying situation of the water flow can be clearly observed, which helps to more accurately evaluate the waterproof performance of the fabric and avoid misjudgment due to insufficient light.

[0074] Specifically, the lighting assembly 5 includes LED spotlights and LED light strips. LED spotlights are installed at the four corners of the top of the display cavity 11. The power of the LED spotlights is 10 watts, the color temperature is 5000K, and the color rendering index is greater than 90, which can provide a bright, clear and natural light-like lighting effect. On the inner walls on both sides of the display cavity 11, five LED light strips are evenly distributed along the height direction. Each LED light strip is 50 cm long and has a power of 5 watts. The LED spotlights and LED light strips are connected to an external power source through wires and are controlled by a control panel 41. The control panel 41 is provided with a switch module, a brightness adjustment module, and a light mode selection module.

[0075] When testing the waterproof performance of fabrics, the observer can select the appropriate lighting mode and brightness through the control panel 41 according to actual needs to ensure the best lighting conditions in the display cavity 11, so as to clearly observe the waterproof performance of the fabrics.

[0076] Embodiment 2

[0077] The embodiment of the present invention further provides a method for using a fabric waterproof performance testing device, which is applied to the fabric waterproof performance testing device provided in the first embodiment, wherein the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment, and the specific steps include:

[0078] The fabric 100 to be tested is cut and fixed by the fixing component 2 .

[0079] Specifically, the fabric 100 to be tested is precisely cut according to the test requirements to ensure that the size and shape of the fabric 100 to be tested meet the test requirements. Then, the positions and clamping strengths of the multiple adjustment clamps 21 are adjusted to ensure that the fabric 100 to be tested is firmly clamped in the display cavity 11 and remains flat to avoid wrinkles or skewness, thereby completing the fixing effect of the fabric 100 to be tested.

[0080] The spray component 3 is started to spray water on the fabric 100 to be tested, and the spray parameters are adjusted through the control component 4.

[0081] Specifically, according to actual test needs, select a suitable spray mode, such as light rain mode, heavy rain mode or rainstorm mode, on the control panel 41, and set parameters such as spray time and spray angle. At the same time, press the control button 42 to start the spray component 3 to achieve the spray effect.

[0082] After the test is completed, the spray assembly 3 is stopped, and the fabric 100 to be tested is disassembled for inspection.

[0083] Specifically, after the test is completed according to the preset time and parameters, the control button 42 is pressed to stop the operation of the spray assembly 3. The fabric 100 to be tested on the fixing assembly 2 is disassembled and subjected to a comprehensive and detailed inspection. The wetness of the fabric surface, whether there are water seepage points, the distribution and shape of water marks, etc. are observed to evaluate the waterproof performance of the fabric.

[0084] Observe whether there is water accumulation or infiltration on the front side of the fabric 100 to be tested, and touch the back side of the fabric 100 to be tested to see if it is wet or water permeable. If the back side is completely dry, it means that the fabric has good waterproof performance in a rainstorm environment.

[0085] The method for using the fabric waterproof performance testing device proposed by the present invention is simple and easy to operate, and does not require cumbersome professional instructions or training. Observers can directly operate the equipment and independently complete the waterproof performance testing experience.
