A water tank is fixed on the top wall of the test box, a spray head is installed at the bottom end of the water tank, and when the support plate is driven by the swing arm assembly to be retracted into the test box, the top of the support plate is close to the spray head, and at the same time, the water that cannot be absorbed during spraying falls to the bottom of the test box for collection.
[0006] Preferred Technical Solution 1: An induction color-changing plate is laid on the top surface of the support plate. When the induction color-changing plate comes into contact with moisture, a chemical reaction will occur, resulting in a color change. When the moisture evaporates, the induction color-changing plate will return to its original color.
[0007] Preferred Technical Solution 2: A heating element is installed inside the support plate, and the heating element is used to dry the induction color-changing plate.
[0008] Preferred Technical Solution 3: Multiple groups of slide rails are fixed around the center on the bottom wall of the water tank, a sliding seat slides on the slide rails, and a set of spray heads are fixed on each sliding seat. The spray heads are connected to the water outlet of the water pump in the water tank through hoses.
[0009] Preferred Technical Solution 4: A lead screw is rotatably arranged inside the slide rail, and the sliding seat is sleeved on the lead screw through a threaded hole.
[0010] Preferred Technical Solution 5: A first bevel gear is fixedly sleeved on the proximal end of each group of the lead screws. A power shaft is rotatably installed at the center of the bottom of the water tank. A second bevel gear fixedly sleeved on the power shaft meshes with the first bevel gears of multiple groups at the same time. A second motor connected to the power shaft is fixed on the water tank.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0022] Please refer to Figures 1-3 , a nursing pad testing device, including a testing box 1, a swing arm assembly 2 is arranged on the inner wall of the testing box 1, a support plate 3 is installed at the bottom end of the swing arm assembly 2, and the support plate 3 is used for laying and placing the nursing pad to be tested. The swing of the swing arm assembly 2 controls the movement of the support plate 3 inside and outside the testing box 1. An induction color-changing plate 6 is laid on the top surface of the support plate 3. When the induction color-changing plate 6 comes into contact with moisture, a chemical reaction will occur, resulting in a color change. When the moisture evaporates, the induction color-changing plate 6 will return to its original color. The induction color-changing plate 6 usually adds specific chemical materials to achieve this effect. For example, anhydrous copper sulfate, anhydrous cobalt chloride or other chemical substances that change color when encountering water are added. These substances present one color in the dry state and will undergo a chemical reaction when in contact with moisture, resulting in a color change. Anhydrous copper sulfate changes from white to blue, while anhydrous cobalt chloride changes from dark blue to pink. This color-changing process is reversible and will return to its original color when the moisture evaporates. A water tank 4 is fixed on the top wall of the testing box 1, and a spray head 5 is installed at the bottom end of the water tank 4. When the support plate 3 is driven by the swing arm assembly 2 to be retracted into the testing box 1, the top of the support plate 3 is close to the spray head 5, thereby avoiding a large amount of splashing when the water sprayed by the spray head 5 falls onto the nursing pad on the support plate 3 due to a high drop. At the same time, when spraying water, the excessive water that cannot be absorbed falls to the bottom of the testing box 1 for collection.
[0023] Please refer to Figure 3 , a nursing pad testing device, an electric heating element 7 is installed inside the support plate 3, and the electric heating element 7 is used to dry the induction color-changing plate 6.

At the same time, the swing arm assembly 2 includes a driving swing arm 21 and a driven swing arm 22. The bottom ends of the driving swing arm 21 and the driven swing arm 22 are hinged to the side edges of the support plate 3 respectively. At the same time, the top ends of the driving swing arm 21 and the driven swing arm 22 are fixedly connected to a first convex shaft 23 and a second convex shaft 24 rotatably arranged on the side wall of the test box 1 respectively. A first motor connected to the first convex shaft 23 is fixed in the test box 1, and the output shaft of the first motor is fixedly connected to the first convex shaft 23 for driving the swing arm assembly 2 to swing. The driving swing arm 21 and the driven swing arm 22 are parallel and of equal length, so that a parallelogram space is formed by the connection lines between the driving swing arm 21, the driven swing arm 22, the first convex shaft 23 and the second convex shaft 24, and the support plate 3. When the driving swing arm 21 swings to drive the support plate 3 to move back and forth, the support plate 3 is always in a flat state.
[0025] Please refer to Figure 2 and Figure 4 , For the nursing pad testing device, multiple groups of slide rails 8 are fixedly arranged around the center on the bottom wall of the water tank 4. A slide seat 9 slides on the slide rails 8. A group of spray nozzles 5 are fixed on each group of slide seats 9. The spray nozzles 5 are connected to the water outlet of the water pump in the water tank 4 through hoses.
