Due to the centrifugal force, the mask will slide to varying degrees. The sliding data of the mask is detected by the displacement detection mechanism, thereby indirectly reflecting the fitting strength of the mask. It can not only simulate the dynamic changes in the actual use environment, but also effectively reduce the influence of human factors on the test results, ensure the standardization and automation of the test process, and improve the reliability and accuracy of the test results.

[0007] By adopting the above technical solutions, the design of the flip frame enables the detection platform to stably carry the mask and maintain good stability during the detection process. The structural design of the rotating side plate and the first and second horizontal plates ensures the firmness and durability of the entire flip frame and improves the overall rigidity of the device. The setting of the visual inspection camera can monitor the displacement of the mask in real time during the rotation of the mask, provide high-precision inspection data, and effectively improve the accuracy and reliability of the mask adhesion test.

[0008] Preferably, the displacement detection mechanism further comprises a lamp holder fixedly connected to the outer wall of the visual detection camera, and the lamp holder is provided with an illumination lamp for illuminating the mask on the detection platform.

[0009] By adopting the above technical solution, adding lamp holders and lighting lamps can effectively improve the lighting conditions of the detection environment, ensure that the visual inspection camera obtains clear mask images, improve the precision and accuracy of displacement detection, reduce misjudgments caused by insufficient light, and enhance the reliability and stability of the entire testing device.

[0011] By adopting the above technical solution, the visual inspection camera can adjust the distance from the inspection platform according to the actual test requirements to ensure the inspection accuracy. Specifically, when the material or thickness of the mask changes, the position of the camera can be flexibly adjusted by adjusting the components so that the camera always maintains the best shooting distance, thereby obtaining clearer and more accurate displacement data and improving the reliability and accuracy of the test results.

By replacing the simulated placement plates for different skin types (dry, oily, and mixed), the degree of adhesion of the mask on different skin types can be obtained. At the same time, there are scale lines on the detection base to facilitate accurate measurement of the sliding distance of the mask at different positions, ensuring the reliability and consistency of the test results.

[0016] Preferably, a groove for placing a simulated placement plate is formed on the end surface of the detection base close to the displacement detection mechanism, and the detection base is provided with an elastic buckle for fixing the simulated placement plate, and a plurality of elastic buckles are provided and distributed around the groove, and the elastic buckle includes a rotating rod located outside the groove and rotatably connected to the detection base, a pressure block axially slidably sleeved on the rotating rod, and a spring provided between the pressure block and the rotating rod and normally forcing the pressure block to slide toward the detection base, the free end of the pressure block is normally pressed against the simulated placement plate, and the free end of the pressure block can rotate around the axis of the rotating rod to the outside of the simulated placement plate.

[0047] The test steps of a facial mask adhesion test device according to an embodiment of the present application are as follows: in an initial state, the rotating side plate 21 is in a vertical state, and the first horizontal plate 22 is located above the second horizontal plate 23; Step S1: Check whether the device is in a closed state to ensure safety; Step S2: Open the detection door panel 14, install the simulated storage plate 32 on the detection base 31, first place the simulated storage plate 32 in the groove 33, apply force to the pressing block 72 so that the pressing block 72 slides upward relative to the rotating rod 71, at this time, the spring 73 undergoes elastic deformation and has elastic potential energy, then rotate the pressing block 72 to drive the rotating rod 71 to rotate together, so that the free end of the pressing block 72 is located above the edge of the simulated storage plate 32, remove the force applied to the pressing block 72, and the pressing block 72 slides downward under the action of the spring 73, and presses the simulated storage plate 32 tightly, so as to fix the simulated storage plate 32 and the detection base 31; Step S3: Lay the mask to be tested flat on the simulated storage plate 32, and the visual inspection camera 41 records the initial position data of the mask; Step S4: close the detection door panel 14 and set a suitable rotation speed and time; Step S5: Start the rotating motor 5 and start the test procedure. The rotating motor 5 rotates to drive the central shaft 24 to rotate, and then drives the flip frame 2 to slowly accelerate to a predetermined speed, thereby driving the detection platform 3 to rotate around the axis of the central shaft 24. Due to the centrifugal force, the mask on the detection platform 3 will slide to varying degrees. The sliding of the mask is observed by the visual detection camera 41, and the final position data of the mask is recorded; Step S6: After the test is completed, the power is turned off and the operation is stopped, and the sample is taken out for the next step of analysis.

[0048] The sliding data of the mask is detected by the visual detection camera 41, which indirectly reflects the fit strength of the mask. It can not only simulate the dynamic changes in the actual use environment, but also effectively reduce the impact of human factors on the test results, ensure the standardization and automation of the test process, and improve the reliability and accuracy of the test results. The degree of fit of the mask on different skin types (dry, oily, mixed) can be obtained by replacing the simulated storage plate 32 for different skin types (dry, oily, mixed).

Specifically, the humidifier 17 is an ultrasonic humidifier 17. The setting of the humidifier 17 can simulate the use environment under different climatic conditions, so as to facilitate a comprehensive test of the mask application performance under different humidity conditions.

The water tank 37 is provided with a water supply pump 371 for pumping water in the water tank 37 to the inner cavity of the simulated storage plate 32.

[0052] The heating rod heats the water in the water tank 37, so that the water can enter the inner cavity of the simulated storage plate 32 through the water inlet pipe 35, and flow back to the water tank 37 through the water outlet pipe 36, forming a circulation system, which can simulate the application performance of the mask under different temperature environments, so as to more comprehensively evaluate the performance of the mask in actual use. In addition, the control valve 38 on the heating rod and the water outlet pipe 36 can be closed, and the water in the water tank 37 can be pumped to the inner cavity of the simulated storage plate 32 through the water supply pump 371, so that the simulated storage plate 32 expands, and then the roughness of the surface of the simulated storage plate 32 is changed, so as to more comprehensively evaluate the performance of the mask in actual use. After the simulated storage plate 32 expands, the water supply pump 371 and the control valve 38 of the water inlet pipe 35 are closed.

[0053] Embodiment 5: The difference from Example 1 is that, referring to Fig.12 , Fig.13 The bottom inner wall of the groove 33 protrudes and is fixedly connected with a positioning boss 332, the simulation plate 32 is provided with a positioning hole 322 for inserting the positioning boss 332, and the free end surface of the pressing block 72 is provided with a socket 723 for inserting the positioning boss 332.
