[0025] To make the objectives, features, and advantages of this application more readily apparent, the present application is further described below in conjunction with the accompanying drawings and specific embodiments. It is apparent that the embodiments described are only a portion of the embodiments of this application, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in this application without inventive effort are also within the scope of protection of this application.

[0026] The inventors analyzed existing technologies and discovered that reading air pressure using existing pressure test dials is subject to human interference, resulting in low reading accuracy and potentially large errors due to the influence of viewing angle. This human factor significantly interferes with test results, making them inaccurate and difficult to reproduce. Furthermore, the existing test molds are made of high-hardness materials, making them incapable of testing goggles with large curvatures.

[0027] Reference Figure 1 , shows a structural schematic diagram of an air tightness detection device for swimming goggles provided by the present application.

[0028] A device for detecting air tightness of swimming goggles, comprising a detection box, a power supply, an air pressure device, an air tightness test controller 7, and a test mold 2 for fixing the swimming goggles to be tested. The air pressure device is fixedly arranged in the detection box, and the air pressure device is connected to the test mold 2. The air tightness test controller 7 is fixedly arranged on the inner wall of the detection box, and the air tightness test controller 7 is electrically connected to the air pressure device. An air outlet is provided on a side of the test mold 2 close to the swimming goggles to be tested. When the air tightness test controller 7 is turned on, the gas in the air pressure device is compressed to the clearance space between the swimming goggles to be tested and the test mold 2.

[0029] It should be noted that the test mold 2 is provided with at least one air outlet at each of the left and right mirror cavities of the swimming goggles to be tested. The number of air outlets is not limited and can be set according to the air pressure value and the size of the swimming goggles.

[0030] It should be noted that the airtightness testing device utilizes a differential pressure method, generating a certain pressure difference within the sealed goggles to detect leakage. During testing, the goggles are secured to a test mold 2. A pneumatic device compresses air into the gap between the goggles and the mold 2 and maintains this pressure for a period of time, simulating the sealing state of the goggles in actual use.

[0031] It should be noted that the test mold 2 can be made of silicone material that simulates a human face. Using a test mold 2 made of soft silicone can realistically simulate human facial skin. Due to the material properties of silicone, it can also fully fit the eyecups of various swimming goggles with different curvatures to be tested, making it applicable to a wider range of eyecup types.

[0032] In the embodiment of the present application, compared with the problem of low accuracy caused by reading the air pressure degree through a digital dial in the prior art and the high hardness of the test mold 2 material, the present application provides a solution for reading the air pressure degree through a controller and an operation panel 5, specifically: including: a detection box, a power supply, an air pressure device, an air tightness test controller 7 and a test mold 2 for fixing the swimming goggles to be tested; an air pressure device is fixedly arranged in the detection box, and the air pressure device is connected to the test mold 2; an air tightness test controller 7 is fixedly arranged on the inner wall of the detection box, and the air tightness test controller 7 is electrically connected to the air pressure device; an air outlet is provided on the side of the test mold 2 close to the swimming goggles to be tested; when the air tightness test controller 7 is turned on, the gas in the air pressure device is compressed to the gap space between the swimming goggles to be tested and the test mold 2. Through the coding program of the airtightness test controller 7, the device can set the target pressure value, pressure stabilization time, pressure holding time and the time of the pressure recording point, and perform the test fully automatically, thereby reducing the errors caused by manual recording, improving the accuracy and reproducibility of the test results, and thus improving work efficiency; the sample test mold 2 is made of soft silicone material. The characteristics of soft silicone can realistically simulate human facial skin. Due to the material properties of silicone, it can also fully fit the eye cups of various swimming goggles with different curvatures to be tested, and is applicable to a wider range of swimming goggles.

[0033] Next, an airtightness detection device for swimming goggles in this exemplary embodiment will be further described.

[0035] In one embodiment of the present application, the test box is embedded with an operation panel 5 , and the operation panel 5 is electrically connected to the airtightness test controller 7 .

[0036] It should be noted that, by setting the target pressure value, pressure stabilization time, pressure holding time and time of the pressure recording point in the operation panel 5, after setting the above parameters, the test is started by clicking the start button.

[0037] In one embodiment of the present application, the test box is embedded with a buzzer 4 , and the buzzer 4 is electrically connected to the operation panel 5 and the air pressure device.

[0038] It should be noted that the air tightness detection device automatically detects the eligibility of the product. When the swimming goggles to be tested have no leakage, the buzzer 4 will emit a sound indicating that the test is qualified; when there is a leakage, the buzzer 4 of the air tightness detection device will emit an alarm sound, indicating that the swimming goggles to be tested are unqualified.

[0039] In one embodiment of the present application, the test box is embedded with an emergency brake button 3 , and the emergency brake button 3 is directly connected to the power supply.

[0040] In one embodiment of the present application, the test box is embedded with a power button 1 , and the power button 1 is electrically connected to the airtightness test controller 7 .

[0041] It should be noted that before testing, you need to turn on the power button 1 of the airtightness test device, enter the main interface of the operation panel 5, click to enter the parameter setting interface, and set the relevant parameters according to the test standards, namely, the inflation time, balance time, test time, exhaust time, etc. After setting the corresponding parameters, you can return to the main test interface.

[0042] In one embodiment of the present application, a heat dissipation device is provided on the inner wall of the detection box, and the heat dissipation device is electrically connected to the airtightness test controller.

[0043] In one embodiment of the present application, the test box is provided with a heat dissipation window.

[0047] In one embodiment of the present application, at least one test mold 2 is detachably provided on the top of the test box body.

[0048] It should be noted that the number of the test molds 2 on the top of the test box is not limited, and the number of the test molds 2 can be limited according to the total number of swimming goggles to be tested.

[0049] It should be noted that the working process of this device is roughly as follows: after turning on the power switch, fix the swimming goggles to be tested and the test mold 2, set the target pressure value, pressure stabilization time, pressure holding time and the time of the pressure recording point through the operation panel 5. After setting the parameters, click the automatic start button to start the test, and the air pump 8 starts to automatically pump air. After reaching the set target pressure value, the air pump 8 automatically stops pumping air and stabilizes the pressure for a preset time. After the pressure stabilization is completed, the pressure is maintained. When the product is full, the air source is cut off, and the pressure sensor inside the device is used to detect the pressure change after the swimming goggles to be tested are inflated, and the pressure value of the set pressure recording point is automatically recorded. Turn off the power and remove the swimming goggles to be tested.
