[0002] Diapers are a common care product for infants and other specific groups of people, and their water absorption is one of the key indicators of product quality. In existing technologies, diaper water absorption test devices often have many shortcomings. Common test devices have simple structures and single functions, and cannot accurately simulate various situations in actual use. For example, the control of the infusion device is not precise enough, making it difficult to achieve liquid delivery at different flow rates and flow rates; the stability and adaptability of the fixing device are poor, and it cannot effectively fix diapers of various sizes and models; there is a lack of control over the test liquid temperature, making it impossible to study the impact of temperature on water absorption; and the limited number of solution tanks makes it difficult to meet the diverse test solution needs. In addition, traditional devices have room for improvement in terms of ease of operation, data accuracy, and comprehensiveness of testing. These shortcomings reduce the reliability of test results and cannot provide strong support for the research and development, production, and quality inspection of diapers. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] The diaper absorbency testing device includes an infusion device and a workbench. The workbench includes a tabletop 1 and support legs 12 at the bottom. The infusion device includes a faucet 21, a water pump 23, and a solution tank 24, which are sequentially connected via an infusion tube. The faucet 21 is provided with a valve 22 and is mounted on the tabletop 1. The tabletop 1 is provided with a fixture. The fixture includes a rotating rod 32 mounted on the tabletop 1, with a mounting platform 33 fixedly connected to the top of the rotating rod 32. The fixture also includes a threaded rod 42 threadedly connected to the mounting platform 33, a handle 41 mounted on the top of the threaded rod 42, and a pressure block 43 connected to the bottom of the threaded rod 42. The tabletop 1 is provided with an inwardly recessed positioning groove 11. The fixtures are provided on both sides of the positioning groove 11. A heating device 211 is installed at the outlet end of the faucet 21. An extension tube 212 is connected to the lower end of the heating device 211, which is located above the positioning slot 11. A weighing platform 5 is located at the bottom of the positioning slot 11. A valve 22 is mounted on the countertop 1. A solution tank 24 is mounted at the bottom of the countertop 1, with a tank opening 241 located at the top. There are at least two solution tanks 24, all of which are connected to the water pump 23 via a liquid infusion tube. The valve 22 is electrically controlled. The bottom of the rotating rod 32 is rotatably connected to the countertop 1 via a bearing 31.

[0028] The working principle of this utility model is as follows:

[0029] First, place the diaper to be tested in the positioning slot 11 on the table 1. Adjust the mounting platform 33 by rotating the rotating rod 32, so that the threaded rod 42 is positioned appropriately above the diaper. Then, rotate the handle 41, driving the threaded rod 42 downward, so that the pressing block 43 at the bottom presses against the diaper, securing it firmly in place.

[0030] Next, select the solution tank 24 based on the test requirements and start the water pump 23. The solution is pumped through the infusion tube to the faucet 21 by the water pump 23. If the flow rate and volume need to be adjusted, this can be controlled via the electronically controlled valve 22 on the countertop 1. As the test liquid passes through the heating device 211 at the outlet end of the faucet 21, it is heated to the set temperature. The heated liquid then drips accurately onto the diaper in the positioning groove 11 through the extension tube 212.

[0031] During the infusion process, a weighing platform 5 at the bottom of the positioning tank 11 monitors the diaper's weight changes in real time. As the test liquid is continuously injected, the diaper absorbs the liquid and gradually increases in weight. The weighing platform 5 transmits the collected weight data to a related data processing system for subsequent analysis of key performance indicators such as the diaper's water absorption rate and water absorption capacity.

[0032] During the test, if it is necessary to switch to a test liquid with different components, it is only necessary to select the corresponding solution tank 24 by controlling the valve 22 and the water pump 23 .

[0033] In addition, the device has various embodiments. For example, multiple positioning slots 11 of different sizes and shapes can be provided to accommodate different types of diapers; the heating device 211 can be set to multiple temperature levels to more accurately simulate urine at different temperatures; and the weighing platform 5 can have data storage and transmission functions to facilitate uploading test data to a computer for more in-depth analysis and processing.

[0034] Through the coordinated work and precise control of the above components, this device can efficiently and accurately complete the test of diaper water absorbency, providing strong support for diaper quality assessment and research and development.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
