[0049] In some embodiments, the switch 142 is a solenoid valve or a pneumatic valve. Of course, the switch 142 is not limited to this; it is acceptable as long as the switch 142 can open or close to connect or disconnect the liquid outlet of the test specimen from the outside.
[0050] For the aforementioned control component 15, please refer to Figure 6The control component 15 includes a second drive member 151, a light-shielding member 152, and a control member 153. The second drive member 151 is mounted on the mounting bracket 113 and connected to the light-shielding member 152. A first detection member is mounted on the light-shielding member 152.

[0056] For the above display component 17, please refer to Figure 1 The display component 17 is disposed on the frame 111. The display component 17 is used to display information transmitted by the controller 18, such as the pressure value detected by the pressure sensor 141, the heating power of the heater of the test piece, the operating voltage of the test piece, the test results, etc.
[0057] For the controller 18 mentioned above, please refer to Figure 1The controller 18 is mounted on the mounting bracket 113 and is electrically connected to the first drive unit 131, the second drive unit 151, the control unit 153, the identification unit 161, the third drive unit 121, the pressure sensor 141, and the switch unit 142.

When the pressure value detected by the pressure sensor 141 is lower than a second preset value within a preset time period, it indicates that the sealing performance of the test piece fails the test, and the controller 18 controls the indicator 19 to emit a red light; otherwise, it indicates that the sealing performance of the test piece passes the test, and the controller 18 controls the indicator light to emit a green light.
[0058] In some embodiments, a leakage value is calculated based on the pressure value detected by the pressure sensor 141 and a first preset value. The calculated leakage value is compared with the preset leakage value. If the calculated leakage value does not exceed the preset leakage value, it indicates that the sealing performance of the test piece has passed the test, and the controller 18 controls the indicator light to emit a green light. Otherwise, it indicates that the sealing performance of the test piece has failed the test, and the controller 18 controls the indicator 19 to emit a red light.
[0059] In some embodiments, please refer to Figure 1 and Figure 7 The test equipment 100 also includes a second detection element 1a, which is disposed on the mounting frame 113 and electrically connected to the controller 18. The second detection element 1a is used to detect whether there is a foreign object extending into the test area of the mounting frame 113, thereby causing the controller 18 to control the test equipment 100 to stop running, thus playing a safety protection role. The test area is the area where the component 12 is placed on the mounting frame 113.
[0060] In this embodiment of the invention, the testing device 100 includes a frame 11, a placement assembly 12, a liquid inlet assembly 13, and a liquid outlet assembly 14.

The pressure sensor 141 is used to connect to the liquid outlet end of the test piece, and the switch 142 connects the pressure sensor 141 to the outside environment, allowing the liquid outlet end of the test piece to be connected to or disconnected from the outside environment. By closing the switch 142, the test piece is sealed, causing the liquid pressure inside the test piece to reach a first preset value and remain at that value for a preset period of time. Then, the pressure sensor 141 detects whether the liquid pressure is lower than a second preset value within the preset period of time, thereby determining whether there is a leak in the test piece and improving testing efficiency.
