Description

Technical Field

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

[0002] Leak-proof sanitary napkins are a type of feminine hygiene product with a special design and function, designed to prevent menstrual blood from leaking from the sides during use. They typically feature widened, longer, and three-dimensional protective designs, and some also have fast absorption and anti-backflow functions, providing more reliable protection for women during menstruation.

[0003] CN209485614U discloses a device for detecting the absorbency of leak-proof sanitary napkins. The sanitary napkin to be tested is placed on the horizontal groove of the model on the sanitary napkin placement platform, and the data of the pressure sensor is recorded at this time. Water is introduced into the water storage chamber from the water inlet, and the water delivery device is moved to directly above the sanitary napkin. The stopcock in the water delivery device is opened, and the water slowly flows down from the slow flow section onto the sanitary napkin. When the humidity sensor shows a jump in data, it indicates that the sanitary napkin has started to leak. The data of the pressure sensor at this time is recorded, so that the amount of liquid accumulated on the sanitary napkin can be calculated.

[0004] This device for testing the absorbency of leak-proof sanitary napkins, although the water delivery device can move laterally to change the position of the water droplets, the position of the placement plate is fixed and the position of the sanitary napkin cannot be adjusted. For larger sanitary napkins, it is difficult to achieve comprehensive testing, which reduces the flexibility of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a device for detecting the absorbency of leak-proof sanitary napkins.

Support columns are fixedly connected to the four corners of the bottom of the testing platform. Universal wheels are fixedly connected to the bottom of the support columns. A water collection tank is formed on the top of the testing platform. A limit rod is fixedly connected to the inner wall of the water collection tank. A fixed seat is slidably connected to the surface of the limit rod. A pressure sensor is fixedly connected to the top of the fixed seat. A placement mold is fixedly connected to the top of the pressure sensor. A humidity sensor is fixedly connected to the inner wall of the placement mold. A mounting frame is fixedly connected to the top of the testing platform. A guide rail is fixedly connected to the front end of the mounting frame. A mounting seat is slidably connected to the inner wall of the guide rail. A water tank is fixedly connected to the top of the mounting seat. A water pipe is connected to the inner wall of the water tank. A drip nozzle is connected to the end of the water pipe away from the water tank. A valve is threadedly connected to the inner wall of the water pipe.

[0007] The above technical solution involves pushing the fixed seat along the limiting rod to move the mold back and forth, adjusting the position of the sanitary napkin, facilitating the detection of different positions on the sanitary napkin, and improving practicality. The application principle of the pressure sensor and humidity sensor has been disclosed in the announcement number CN209485614U, which is already disclosed technology and is not described in detail in this application.

[0008] As a further improvement to the above solution, the bottom of the testing platform is connected to a drain pipe, which is connected to a water collection tank.

[0009] With the above technical solution, when there is water inside the water collection tank, it can be discharged through the drain pipe.

[0010] As a further improvement to the above solution, two limiting rods are provided, and the two limiting rods are symmetrically distributed with the water collection tank as the center.

[0011] The above technical solution uses a limiting rod to limit the movement of the fixed seat, thereby improving the stability of the fixed seat during movement.

[0012] As a further improvement to the above solution, an extension plate is fixedly connected to the front end of the mounting base, and a mounting frame is fixedly connected to the bottom of the extension plate.

[0013] As a further improvement to the above solution, a fan is fixedly connected to the top of the inner wall of the mounting frame.

[0014] The above technical solution uses a blower to blow air onto the mold to dry the water stains, making it easier for subsequent testing.

[0015] As a further improvement to the above solution, a heating pipe is fixedly connected to the inner wall of the mounting frame, and the heating pipe is located at the lower end of the fan.

[0016] The above technical solution heats the air blown out by the fan through a heating tube, thereby improving drying efficiency and thus improving testing efficiency.

[0017] As a further improvement to the above solution, the number of heating tubes is set to several.

[0018] The above technical solution improves the heating effect by using several heating tubes.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model, by setting a limiting rod and a fixing seat, specifically by pushing the fixing seat along the limiting rod, drives the mold to move back and forth, adjusting the position of the sanitary napkin, facilitating the detection of different positions of the sanitary napkin, and improving its practicality.

[0021] This invention improves testing accuracy and efficiency by setting up an installation frame, a fan, and a heating element. Specifically, by starting the fan and heating element, the heating element generates heat, and the airflow blown out by the fan comes into contact with the heating element, forming hot air that blows onto the mold, thereby drying the moisture on the surface of the mold for the next test.

A fixed seat 6 is slidably connected to the surface of the limit rod 5. A pressure sensor 7 is fixedly connected to the top of the fixed seat 6. A placement mold 8 is fixedly connected to the top of the pressure sensor 7. A humidity sensor 9 is fixedly connected to the inner wall of the placement mold 8. A mounting frame 10 is fixedly connected to the top of the testing platform 1. The front of the mounting frame 10... A guide rail 11 is fixedly connected to the end of the device. A mounting base 12 is slidably connected to the inner wall of the guide rail 11. A water tank 13 is fixedly connected to the top of the mounting base 12. A water pipe 14 is connected to the inner wall of the water tank 13. A drip nozzle 15 is connected to the end of the water pipe 14 away from the water tank 13. A valve 16 is threadedly connected to the inner wall of the water pipe 14. The sanitary napkin to be tested is placed inside the placement mold 8. The valve 16 is opened so that the water inside the water tank 13 enters the drip nozzle 15 through the water pipe 14. The water is slowly dripped onto the sanitary napkin through the drip nozzle 15. When the humidity sensor 9 shows a jump in data, it indicates that the sanitary napkin has started to leak.

[0032] The bottom of the testing platform 1 is connected to a drain pipe 17, which is connected to the water collection tank 4.

[0033] There are two limit rods 5, which are symmetrically distributed around the water collection tank 4. By pushing the fixed seat 6 to move along the limit rods 5, the mold 8 is moved back and forth to adjust the position of the sanitary napkin, which facilitates the detection of different positions of the sanitary napkin and improves its practicality.

[0034] An extension plate 18 is fixedly connected to the front end of the mounting base 12, and a mounting frame 19 is fixedly connected to the bottom of the extension plate 18.

[0035] A fan 20 is fixedly connected to the top of the inner wall of the mounting frame 19.

[0036] A heating tube 21 is fixedly connected to the inner wall of the mounting frame 19. The heating tube 21 is located at the lower end of the fan 20. After the test is completed, the sanitary napkin is removed, and the fan 20 and the heating tube 21 are started. The heating tube 21 generates heat, and the air blown out by the fan 20 comes into contact with the heating tube 21, forming hot air that blows towards the placement mold 8, thereby drying the moisture on the surface of the placement mold 8 so that it can be tested again, thus improving the accuracy and efficiency of the test.

[0037] The number of heating tubes 21 is set to several.

[0038] The implementation principle of the device for detecting the absorbency of leak-proof sanitary napkins in this application embodiment is as follows: During use, the sanitary napkin to be tested is placed inside the placement mold 8. The valve 16 is opened, allowing water from the water tank 13 to enter the drip nozzle 15 through the water pipe 14. Water is slowly dripped onto the sanitary napkin through the drip nozzle 15. When the humidity sensor 9 shows a jump in data, it indicates that the sanitary napkin has started to leak. When different positions of the sanitary napkin need to be tested, the fixed base 6 is pushed along the limiting rod 5, thereby moving the placement mold 8 back and forth to adjust the position of the sanitary napkin, facilitating testing at different positions and improving practicality. After testing, the sanitary napkin is removed, and the fan 20 and heating element 21 are started. The heating element 21 generates heat, and the airflow from the fan 20 contacts the heating element 21, forming hot air that blows onto the placement mold 8, drying the surface of the placement mold 8 for the next test, thus improving testing accuracy and efficiency.
