[0001] The utility model relates to the technical field of salt spray testing machines, and more specifically to a salt spray testing machine. Background Art
[0002] Salt spray test is a test method specifically for testing the corrosion resistance of various material surfaces. It is mainly used to test hardware, electroplating, electronics, chemicals, automotive parts, aerospace parts and communication parts. It can simulate the corrosion test of the marine environment to analyze and evaluate the performance of the product.
[0003] Since the existing salt spray test machine needs to perform continuous atomization tests in the chamber, the pressure in the chamber will continue to increase, which will cause excessive pressure changes during the test, thereby causing inaccurate test data.

For example, the fog at the corners is relatively thin. Therefore, it is also necessary to design the structure inside the chamber so that the fog inside the chamber is uniform, which is conducive to the atomization test of the product.

[0020] The components to be tested are supported and placed using the placement net 7, and then the first fan 8 installed at the bottom and the second fan 11 installed on the bottom of the box cover 2 are used to blow air on the upper and lower sides of the components, so that the salt mist generated by the atomization device 5 is quickly diffused to all parts inside the entire test box 1, which greatly improves the uniformity of the salt mist inside the test box 1. At the same time, the first fan 8 and the second fan 11 correspond to the components up and down, so that the salt mist is fully in contact with the components, thereby greatly improving the test effect on the components and further improving the accuracy of the test.
[0021] Two heating rods 12 are detachably mounted on both sides of the test box 1 above the support plate 4, and a temperature sensor 13 is detachably mounted on the back of the test box 1 above the support plate 4;
[0022] By stably heating the interior of the test box 1 through the provided heating rod 12 and temperature sensor 13, the tested component is kept in the same stable environment as the working environment, thereby greatly improving the accuracy of the salt spray test on the component.
[0023] Wind holes 10 are provided around one end of the installation pipe 9 close to the box cover 2, and the four wind holes 10 are evenly arranged along the outer circumferential direction of the installation pipe 9. The four wind holes 10 are used to connect the installation pipe 9 with the air inside 1, so that the rotating second fan 11 absorbs the salt mist inside the test box 1 and discharges it from the bottom of the installation pipe 9 to blow it onto the test component.
