Description

Technical Field

[0001] This utility model relates to the field of sanitary napkin testing, and in particular to a sanitary napkin absorbency testing device. Background Technology

[0002] As an essential product for women during menstruation, the absorbency of sanitary napkins directly affects the comfort and health safety of users. The absorbency test of sanitary napkins needs to combine national standards and laboratory methods, covering multiple dimensions such as absorbency ratio, absorption speed, and water retention performance, and using professional equipment to ensure the objectivity and comparability of the data.

[0003] The reference patent title is: A device for testing the absorbency of sanitary napkins (Patent Publication No.: CN219320039U). It uses a clamping assembly to firmly fix the sanitary napkin, preventing it from shifting under force during absorbency testing. Two sanitary napkins are placed against the curved sides of two curved plates, causing them to bend and simulate the state of a sanitary napkin worn on the body. A vibration assembly causes the sanitary napkins fixed to the curved plates to vibrate to simulate the absorbency test when a person is walking or exercising while wearing a sanitary napkin. A second measuring cylinder is installed on one side of the support leg. Liquid inside the support plate flows into the second measuring cylinder, while liquid is dripped onto the surface of the sanitary napkin from the first measuring cylinder. The absorbency is calculated by the ratio of the first and second measuring cylinders.

[0004] However, the following problems exist when implementing the above technical solutions: the data obtained by the above devices have certain errors due to environmental factors, and the overflow liquid after the sanitary napkin is fully soaked needs to pass through the arc plate, the water receiving groove on the surface of the support plate, and the water guide pipe before entering the second measuring cylinder. During the flow of the overflow liquid, it is difficult to avoid losses. Furthermore, due to the up-and-down movement of the support plate during the detection process, the water guide pipe will move inside the second measuring cylinder. When there is a lot of overflow liquid, the movement of the water guide pipe will inevitably cause the overflow liquid in the second measuring cylinder to splash, further increasing the data error and affecting the detection results.

[0005] Therefore, this utility model proposes a sanitary napkin absorbency testing device. Utility Model Content

[0029] The device comprises a fixed block 2 and a movable block 3. The fixed block 2 is fixedly disposed on the surface of the testing platform 1, and the movable block 3 is slidably disposed on the surface of the testing platform 1. Both the fixed block 2 and the movable block 3 have arc-shaped cross-sections. Both the fixed block 2 and the movable block 3 are provided with positioning components for fixing the sanitary napkin. Both the fixed block 2 and the movable block 3 have two guide grooves 4, which are symmetrically arranged. The farthest distance between the two guide grooves 4 is greater than the width of the sanitary napkin.

[0030] The receiving box 5 is detachably mounted on the surface of the testing table 1. The moving block 3, the receiving box 5, and the fixed block 2 are spaced apart. The depth of the guide groove 4 on the side closer to the receiving box 5 is greater than the depth on the other side. The guide groove 4 located in the moving block 3 is rotatably connected to the guide block 6. A driving component is provided between the guide block 6 and the testing table 1. The driving component is slidably mounted on the surface of the guide block 6.

[0031] In summary, the sanitary napkin absorbency testing device provided by this utility model includes a movable block 3, a receiving box 5, and a fixed block 2 arranged at intervals, all three of which are disposed on the surface of the testing platform 1. The receiving box 5 is disposed between the movable block 3 and the fixed block 2. The surfaces of the movable block 3 and the fixed block 2 are provided with guide grooves 4 of varying depths. The guide grooves 4 promote the flow of overflowing liquid into the receiving box 5, thereby reducing the flow path of the overflowing liquid, reducing the loss of overflowing liquid, and reducing errors. The guide grooves 4 in the movable block 3 are provided with rotatable guide blocks 6. The guide blocks 6 change the sliding path of the overflowing liquid, ensuring that the overflowing liquid can flow into the receiving box 5 after the position of the movable block 3 changes. After the sanitary napkin is fixed between the movable block 3 and the fixed block 2, the absorbency test is performed. The overflowing liquid from the sanitary napkin will move along the guide grooves 4 into the receiving box 5. The overflowing liquid directly enters the receiving box 5, avoiding loss during the movement and reducing errors.

[0032] In some specific implementations, a support frame is slidably provided on the surface of the testing platform 1, and a drip bucket 17 is detachably connected inside the support frame. An eccentric wheel is rotatably connected to the surface of the support frame, and the eccentric wheel contacts the testing platform 1.

[0033] In some specific implementations, the driving assembly includes a sliding post 7 fixedly disposed at one end of the guide block 6, a sliding groove 8 formed inside the moving block 3, the sliding post 7 being adapted to the sliding groove 8, a guide rod 9 rotatably connected inside the detection stage 1, a straight groove 10 formed on the surface of the guide rod 9, the sliding post 7 being adapted to the straight groove 10, and an angle between the edge of the sliding groove 8 and the edge of the straight groove 10; the sliding path of the sliding post 7 can be restricted by the sliding groove 8 on the surface of the moving block 3 and the straight groove 10 on the surface of the guide rod 9, and the guide rod 9 is rotatably disposed on the surface of the detection stage 1, the rotation of the guide rod 9 causing the sliding post 7 to rotate, thereby changing the angle of the guide block 6;

[0034] In a further embodiment, the cross-section of the sliding groove 8 is arc-shaped; the arc-shaped sliding groove 8 reduces the horizontal distance of the sliding column 7, slows down the changing trend of the guide block 6, and ensures the overall smoothness of the guide block 6.

[0035] In a further embodiment, a U-shaped block 11 is fixedly connected to the surface of the detection table 1, the surface of the moving block 3 inside the U-shaped block 11 is in contact with it, the surface of the U-shaped block 11 is rotatably connected to the guide rod 9, and a control component is provided between the U-shaped block 11 and the moving block 3; by setting the U-shaped block 11, the sliding trajectory of the moving block 3 is restricted;

[0036] In a further embodiment, the control component includes a control rod 12 rotatably disposed on the side of the movable block 3 away from the receiving box 5, the control rod 12 being threadedly connected to the U-shaped block 11; the position of the movable block 3 can be quickly adjusted via the control rod 12;

[0037] In some specific implementations, the positioning component includes a positioning rod 18, which is threadedly connected to the moving block 3 or the fixed block 2;

[0038] In some specific implementations, a limiting block 13 is slidably connected inside the receiving box 5. The limiting block 13 has an isosceles trapezoidal cross-section. The dimension of the limiting block 13 on the side closer to the detection table 1 is larger than the dimension on the other side, and the distance between the side of the limiting block 13 and the receiving box 5 is greater than zero. The density of the limiting block 13 is less than the density of the overflowing liquid. By setting the limiting block 13, the splashing or movement of the overflowing liquid can be limited, thereby preventing the overflowing liquid from flowing out during vibration.

[0039] In some specific implementations, a telescopic block 14 is detachably connected between the receiving box 5 and the moving block 3. A one-way groove 15 is formed on the surface of the receiving box 5, and a one-way valve (not shown in the figure) is installed inside the one-way groove 15. The edge of the one-way groove 15 contacts the edge of the telescopic block 14. Four locking rods 16 are slidably connected inside the telescopic block 14, with two locking rods 16 arranged symmetrically. A return spring is fixedly connected between each locking rod 16. Both the receiving box 5 and the moving block 3 have locking grooves inside, and the locking rods 16 are adapted to the locking grooves. The telescopic block 14 facilitates a receiving structure between the receiving box 5 and the moving block 3. If liquid overflows during movement and detaches from the guide block 6, it can be received by the telescopic block 14 and its flow guided.

[0040] The working principle of this utility model:

[0041] In use, first adjust the position of the moving block 3 according to the size of the sanitary napkin, rotate the control lever 12 to make the moving block 3 slide inside the U-shaped block 11. During the sliding of the moving block 3, the position of the sliding column 7 changes, causing the guide rod 9 to rotate, which in turn drives the guide block 6 to rotate. After the position of the moving block 3 is determined, place the sanitary napkin on the surface of the moving block 3 and the fixed block 2, and fix it by the positioning rod 18. Add liquid to the surface of the sanitary napkin through the drip bucket 17. You can choose to rotate the eccentric wheel to make the detection platform 1 slide back and forth. After the sanitary napkin is full, the overflowing liquid slides along the guide groove 4 and the guide block 6 into the receiving box 5. After the test is completed, compare the liquid volume inside the receiving box 5 with the liquid volume inside the drip bucket 17.

[0042] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto.
