Description
Technical Field
[0001] This utility model relates to the field of mobile phone case manufacturing technology, specifically a protective structure for salt spray corrosion testing. Background Technology
[0002] After a phone case is manufactured, it needs to undergo a salt spray test to assess its resistance to sweat corrosion, thus simulating the phone case's corrosion resistance in a salt spray environment.
[0003] However, after the test, the large amount of salt spray suspended matter remaining in the salt spray testing equipment can easily diffuse into the external environment when the equipment is turned on, which not only poses a risk of corrosion to surrounding electronic equipment, but also threatens the health of operators. In addition, existing equipment generally lacks an effective device for recovering residual salt spray, resulting in resource waste and increased equipment operating costs. Utility Model Content
[0004] This utility model addresses the technical problems existing in the prior art by providing a protective structure for salt spray corrosion testing. It solves the problem that after the test, a large amount of salt spray suspended matter remaining inside the testing equipment can easily diffuse into the external environment when the equipment is turned on, posing a corrosion risk not only to surrounding electronic equipment but also threatening the health of operators.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A protective structure for salt spray corrosion testing, comprising:
[0006] frame;
[0007] A test chamber, which is mounted on a frame, has a top opening covered by a cover;
[0008] A spraying assembly, which is disposed inside the test chamber, is used to spray salt spray into the test chamber.
[0009] Multiple supports are located inside one side of the test chamber for placing test materials;
[0010] The circulation assembly includes a negative pressure section for extracting salt spray and a collection section for collecting the salt spray extracted by the negative pressure section and supplying it to the spraying assembly. The negative pressure section is located on the other side of the test chamber, and the collection section is located between the spraying assembly and the negative pressure section.
[0011] The beneficial effects of this utility model are:
[0012] 1. After the test, the protective structure can quickly extract the residual salt mist in the test chamber using the negative pressure section, preventing the residual salt mist in the test chamber from spreading to the external environment. This effectively solves the problem of salt mist leakage, not only protecting the surrounding electronic instruments and equipment from corrosion, but also reducing the impact of salt mist on the health of operators and improving the safety of the working environment. At the same time, the collection section can recover the extracted salt mist liquid and recycle it to the spraying components, reducing the amount of salt mist liquid used and reducing operating costs.
[0013] Based on the above technical solution, the present invention can be further improved as follows.
[0014] Furthermore, the negative pressure unit includes a negative pressure unit and an extraction tube. One end of the extraction tube passes through the test chamber and extends into the test chamber, while the suction end of the negative pressure unit is located at the other end of the extraction tube.
[0015] Furthermore, the spraying assembly includes multiple atomizing nozzles, which are disposed on the inner sidewall of the test chamber.
[0016] Furthermore, the collection unit includes a collection chamber, a circulation pipe, and a water pump. The collection chamber is connected to the output end of the negative pressure fan, the suction end of the water pump is connected to one side of the collection chamber, one end of the circulation pipe is located at the output end of the water pump, and the other end of the circulation pipe extends into the interior of the test chamber and is connected to multiple atomizing nozzles.
[0017] The beneficial effect of adopting the above-mentioned further solution is that negative pressure airflow is introduced into the extraction tube by a negative pressure machine, and the extraction tube quickly adsorbs the salt spray particles suspended in the test chamber with the help of the negative pressure airflow, and the adsorbed salt spray is transported to the collection chamber for collection through the output end of the negative pressure machine.
[0018] The water pump draws salt mist liquid from the collection chamber through its suction end and transports the liquid salt mist to the atomizing nozzle through the circulation pipe. The atomizing nozzle then re-atomizes the salt mist and sprays it evenly onto the surface of the phone case in the test chamber, thus realizing the recycling of salt mist.
[0019] Furthermore, each of the brackets includes a support rod, a spring piece, and multiple limiting grooves. The support rod is fixed to the bottom inside the test chamber, and the multiple limiting grooves are arranged in a linear array on the top of the support rod. The spring piece is fixed to the side wall of each limiting groove.
[0020] The beneficial effect of adopting the above-mentioned further solution is that when the phone case is placed between the spring and the side wall of the limiting groove, the phone case can be locked in the limiting groove by the elastic clamping of the spring.
[0021] Furthermore, one side of the spring is arc-shaped.
[0022] The beneficial effect of adopting the above-mentioned further solution is that the arc-shaped design can reduce the frictional resistance between the phone case and the spring, allowing the clamped phone case to be quickly pulled out of the limiting groove, improving the smoothness of picking up and putting down the phone case, and further improving the testing efficiency.

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0029] After a phone case is manufactured, it needs to undergo a salt spray test to assess its resistance to sweat corrosion, thus simulating the phone case's corrosion resistance in a salt spray environment.
[0030] However, after the test, a large amount of salt spray suspended matter remaining in the salt spray testing equipment can easily diffuse into the external environment when the equipment is turned on, which not only poses a risk of corrosion to surrounding electronic equipment, but also threatens the health of operators. In addition, existing equipment generally lacks an effective device for recovering residual salt spray, resulting in resource waste and increased equipment operating costs. In response, the inventor has proposed a protective structure for salt spray corrosion testing to solve the above problems.
[0031] The present invention provides the following preferred embodiments.
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a protective structure for salt spray corrosion testing includes:
[0033] Rack 10;
[0034] Test chamber 20 is mounted on the rack 10, and the top opening of the test chamber 20 is covered by a chamber cover 201;
[0035] The spraying assembly 30 is disposed inside the test chamber 20 and is used to spray salt spray into the test chamber 20.
[0036] Multiple supports 40 are located inside one side of the test chamber 20 for placing test materials;
[0037] The circulation assembly 50 includes a negative pressure section 510 for extracting salt spray and a collection section 520 for collecting the salt spray extracted by the negative pressure section 510 and supplying it to the spray assembly 30. The negative pressure section 510 is located on the other side of the test chamber 20, and the collection section 520 is located between the spray assembly 30 and the negative pressure section 510.
[0038] After the test, the protective structure can quickly extract the residual salt mist in the test chamber 20 using the negative pressure unit 510, preventing the residual salt mist in the test chamber 20 from spreading to the external environment. This effectively solves the problem of salt mist leakage, not only protecting the surrounding electronic instruments and equipment from corrosion, but also reducing the impact of salt mist on the health of operators and improving the safety of the working environment. At the same time, the collection unit 520 can recover the extracted salt mist liquid and recycle it to the spraying assembly 30, reducing the amount of salt mist liquid used and reducing operating costs.
[0039] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the negative pressure section 510 includes a negative pressure unit 511 and an extraction pipe 512. One end of the extraction pipe 512 passes through the test chamber 20 and extends into the test chamber 20. The suction end of the negative pressure unit 511 is located at the other end of the extraction pipe 512. The spray assembly 30 includes multiple atomizing nozzles, which are located on the inner side wall of the test chamber 20. The collection section 520 includes a collection chamber 521, a circulation pipe 522, and a water pump 523. The collection chamber 521 is connected to the output end of the negative pressure fan. The suction end of the water pump 523 is connected to one side of the collection chamber 521. One end of the circulation pipe 522 is located at the output end of the water pump 523, and the other end of the circulation pipe 522 extends into the interior of the test chamber 20 and is connected to the multiple atomizing nozzles.
[0040] Negative pressure airflow is introduced into the extraction tube 512 by the negative pressure compressor 511. The extraction tube 512 uses the negative pressure airflow to quickly adsorb the salt mist particles suspended in the test chamber 20, and the adsorbed salt mist is transported to the collection chamber 521 for collection through the output end of the negative pressure compressor 511.
[0041] The water pump 523 draws salt mist liquid from the collection chamber 521 through its suction end and transports the liquid salt mist to the atomizing nozzle through the circulation pipe 522. The atomizing nozzle then re-atomizes the salt mist and sprays it evenly onto the surface of the mobile phone case in the test chamber 20, thus realizing the recycling of salt mist.
[0042] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, each bracket 40 includes a support rod 401, a spring piece 403 (the spring piece 403 may be made of chromium-containing stainless steel), and multiple limiting grooves 402. The support rod 401 is fixed to the bottom inside the test chamber 20. Multiple limiting grooves 402 are linearly arrayed on the top of the support rod 401. The spring piece 403 is fixed on the side wall of each limiting groove 402. When a mobile phone case is placed between the spring piece 403 and the side wall of the limiting groove 402, the mobile phone case can be locked in the limiting groove 402 by the elastic clamping of the spring piece 403.
[0043] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, one side of the spring piece 403 is arc-shaped. The arc-shaped design can reduce the frictional resistance between the phone case and the spring piece 403, so that the clamped phone case can be quickly pulled out of the limiting groove 402, improving the smoothness of picking up and putting down the phone case and further improving the testing efficiency.
[0044] The specific working process of this utility model is as follows:
[0045] (1) Collect the salt spray to prevent it from spreading.
[0046] First, after the salt spray test of the phone case is completed, negative pressure airflow is introduced into the extraction tube 512 through the negative pressure machine 511. The extraction tube 512 uses the negative pressure airflow to quickly adsorb the salt spray particles suspended in the test chamber 20, and then the adsorbed salt spray is transported to the collection chamber 521 for collection through the output end of the negative pressure machine 511.
[0047] (2) Recycling
[0048] The water pump 523 draws salt mist liquid from the collection chamber 521 through its suction end and transports the liquid salt mist to the atomizing nozzle through the circulation pipe 522. The atomizing nozzle then re-atomizes the salt mist and sprays it evenly onto the surface of the mobile phone case in the test chamber 20, thus realizing the recycling of salt mist.
[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
