[0027] It should be noted that, as can be understood by those skilled in the art, the present invention does not impose too many restrictions on the depth of the test box 1, the preset test depth and the preset stay time. For example, when the waterproof test device is used for IPX7 waterproof test, the depth of the test box 1 is greater than 1 meter to ensure that the liquid level in the test box 1 is greater than 1 meter; the value of the preset test depth is not less than 1 meter and not higher than the depth of the test box 1, so that the product to be tested 7 can be immersed in a suitable test depth; the value of the preset stay time is not less than 30 minutes, so that the product to be tested 7 can be immersed for a suitable test time. When the waterproof test device is used for IPX8 waterproof test, if referring to the national standard "Road Vehicles-Protection Levels for Electrical and Electronic Equipment (IP Code)" (GB / T 30038-2013), the depth of the test box 1, the preset test depth and the preset stay time can be customized.

[0028] In addition, the present invention does not impose too many restrictions on the preset height of the separation from the liquid level, and it is only necessary to make the mesh fixing member 3 rise above the liquid level.

[0029] Preferably, the control system 5 is arranged on the outer wall of the test box 1, and the control system 5 includes a lifting controller (not shown in the figure), a timer (not shown in the figure), a position acquisition module (not shown in the figure) and an operation panel 51.

[0030] Thus, the operation panel 51 is connected to the lifting controller, and the lifting controller can be started through the operation panel 51 to control the lifting structure 2 to drive the mesh fixing member 3 to move and receive the preset test depth and the preset height of the liquid surface, so that the test conditions can be quickly changed, so that the waterproof test device can be quickly applied to tests of different waterproof levels, thereby improving the test efficiency. The operation panel 51 is also connected to the timer, and the preset stay time can be received through the operation panel 51, so that the test time can be accurately controlled. The signal output end of the sensor component 4 is connected to the input end of the position acquisition module, and the output end of the position acquisition module is connected to the lifting controller. The position acquisition module is configured to: obtain the distance between the bottom end of the mesh fixing member 3 and the liquid surface according to the measurement value of the sensor component 4, and transmit the distance between the bottom end of the mesh fixing member 3 and the liquid surface to the lifting controller, so as to lay a foundation for the lifting controller to control the product to be tested 7 to sink to the depth required for the waterproof test and to control the product to be tested 7 to rise to leave the immersion liquid after the test.

[0031] Preferably, the lifting structure 2 includes a fixing frame 21 arranged on the top of the test box 1, a bidirectional motor 22 fixedly mounted on the fixing frame 21, a first rotating wheel 23 connected to the driving end of the bidirectional motor 22, a second rotating wheel 24 fixedly arranged at the bottom of the test box 1, and a lifting transmission member 25 sleeved on the outside of the first rotating wheel 23 and the second rotating wheel 24; the bidirectional motor 22 is connected to the control system 5, and the mesh fixing member 3 is connected to the lifting transmission member 25.

[0032] Specifically, in one exemplary embodiment, the first rotating wheel 23 and the second rotating wheel 24 are both sprocket wheels 231, the second rotating wheel 24 is arranged directly below the first rotating wheel 23, the lifting transmission member 25 is a chain 251 matching the sprocket wheel 231; the mesh fixing member 3 is connected to the chain 251 through a buckle 252. Thus, the lifting and lowering of the mesh fixing member 3 can be achieved through the transmission of the sprocket wheel 231 and the chain 251; the mesh fixing member 3 is connected to the chain 251 by providing the buckle 252, so that the mesh fixing member 3 is easy to disassemble.

Thus, by providing the mesh basket 31 to fix the product to be tested 7, each side of the product to be tested 7 can be more fully in contact with the immersion liquid; by providing the connecting member 32 to fix the product to be tested 7 at the bottom of the mesh basket 31, the product to be tested 7 will not float due to its light weight; by providing at least two buckles 252 on the side wall of the mesh basket 31 to connect with the chain 251, the connection between the mesh basket 31 and the chain 251 can be more stable, thereby avoiding affecting the stability of the product to be tested 7.

[0034] Specifically, the product to be tested 7 is provided with a through hole, the bottom of the basket 31 has mesh holes, the connecting member 32 includes bolts, and the product to be tested 7 and the basket 31 are fixedly connected via the through hole, the mesh holes and the bolts.

[0035] It should be noted that, as can be understood by those skilled in the art, the present invention does not impose too many restrictions on the connection method between the product to be tested 7 and the mesh fixing member 3. For example, in some other embodiments, the product to be tested 7 can also be bound to the mesh fixing member 3 by a rope.

[0036] Further, the sensor assembly 4 includes a distance sensor 41 and a liquid level sensor 42 arranged at the bottom of the test box 1, and the distance sensor 41 is located below the mesh fixing member 3. Therefore, by arranging the distance sensor 41 at the bottom of the test box 1 and below the mesh fixing member 3, the distance from the bottom end of the mesh fixing member 3 to the bottom of the test box 1 can be directly measured; by arranging the liquid level sensor 42 at the bottom of the test box 1, the liquid level in the test box 1 can be measured more accurately.

[0037] It should be noted that, as those skilled in the art can understand, the present invention does not impose too many restrictions on the type and setting position of the sensor assembly 4. In some other embodiments, the sensor assembly 4 may also include two distance sensors 41, one of which is arranged at the bottom of the test box 1 and below the mesh fixing member 3, and the other is arranged at the top of the test box 1.

Therefore, by providing the automatic water replenishing device 6, the immersion liquid in the test box 1 can always be maintained at a level that can be tested, thereby further improving the test efficiency.

[0039] It should be noted that, as can be understood by those skilled in the art, the present invention does not impose too many restrictions on the type of the automatic water replenishment device 6.

When the liquid level in the test box 1 is not higher than the preset lower limit value, the water replenishment controller controls the solenoid valve to open for water replenishment, and when the liquid level in the test box 1 is not lower than the preset upper limit value, the water replenishment controller controls the solenoid valve to close and stop water replenishment.

[0040] In order to better understand the present invention, please continue to refer to Figure 1 and Figure 2 , for example, taking the IPX7 waterproof test of light and small equipment as an example, the use of the waterproof test device provided by the utility model is described:

After the basket 31 stays for 30 minutes, the lifting controller automatically controls the bidirectional motor to reverse, so that the lifting structure 2 drives the basket 31 to rise to 0.02 meters above the liquid surface.

[0044] Finally, the light and small device is taken out from the basket 31 and the test results are observed.
