[0002] Electronic components are an important part of various equipment and instruments, and provide stable support for the normal operation of the equipment. However, after being manufactured, electronic components need to undergo a series of tests and finally pass the tests before they can be installed on the equipment. For example, salt spray resistance testing is required. Because in outdoor operations and sailing scenarios, electronic components are exposed to the air, which is equivalent to being naked. Therefore, electronic components need to be tested with salt spray resistance testing equipment to determine their durability.

[0003] For example, prior art application number CN202320454771.2 discloses an electronic component salt spray resistance test bench, comprising a workbench, a U-shaped frame installed on the top wall of the workbench, a first protective frame installed on the rear wall of the U-shaped frame, a detection assembly installed on the top wall of the U-shaped frame, a placement assembly installed on both the left and right sides of the top wall of the workbench, and a controller installed on the right side of the top wall of the U-shaped frame; the detection assembly comprises a micro liquid pump, a water inlet of the micro liquid pump is connected to a water inlet pipe, a holding box is installed on both the left and right sides of the rear wall of the first protective frame, a connecting pipe is connected to the top wall of the holding box, a drain outlet of the micro liquid pump is connected to a drain pipe, the bottom ends of the drain pipes are connected to spray hoods, a first solenoid valve is installed on both the left and right sides of the drain pipe, and a second solenoid valve is installed on both the left and right sides of the outer wall of the water inlet pipe;

[0004] The above-mentioned prior art has been found through actual use. It is known that it mainly generates mist through a spray hood to cover the electronic components. Then the staff observes the electronic components through a transparent observation window to understand the salt spray resistance results of the electronic components. However, it is found in use that when the staff observes the surface of the electronic components during the salt spray resistance test, the mist dissipates slowly and is easily blocked by the mist, causing blurred vision. If the transparent observation window is opened too many times, the temperature inside the box will drop and affect the test results, thereby causing many inconveniences in observing the salt spray resistance test. In serious cases, it will affect the salt spray resistance test effect. For this reason, we have improved the above-mentioned scheme based on actual usage. Utility Model Content

[0021] refer to Figure 1 and Figure 2 The box 1 is provided with a temperature detector 6 and an electric heater 7 for heating the brine in the bottom of the box 1 to a temperature of 5-40 degrees Celsius. A control panel 5 is fixed to the upper surface of the box 1. A crossbar 8 is fixed between the left and right inner walls of the box 1, and a net box 9 is fixed to the inner wall of the box 1.

[0022] refer to Figure 2 and Figure 3 as well as Figure 4 Axial fan 42 has a first gear 45 mounted on the lower surface of its rotor core, which rotates via a connecting shaft. When axial fan 42 rotates, the connecting shaft drives first gear 45 to rotate. A mounting bracket 44 is bolted to the rear wall of housing 1. A second gear 46 and a third gear 47 are mounted on the lower surface of mounting bracket 44, which are rotatably mounted via connecting shafts. The upper end of the connecting shaft, which is fixed to the upper surface of third gear 47, passes through mounting bracket 44 and is fixed to the lower surface of scraper 43. Second gear 46 meshes with third gear 47 and first gear 45 to drive scraper 43 to rotate.

[0023] Working principle: First, the mixed salt water is injected into the box 1, and then the electronic components are placed on the crossbar 8 or the mesh box 9. Then, the electric heater 7 and the defogging element 4 are activated through the touch screen on the control panel 5 so that the salt water at a certain temperature forms mist to cover the electronic components.

[0024] During the observation process, the axial flow fan 42 in the defogger 4 can be started to rotate to absorb the fog in the box body 1 and finally discharge it through the bend 41, so that the fog in the box body 1 can be quickly removed; after the axial flow fan 42 is started, it will simultaneously drive the No. 1 gear 45, the No. 2 gear 46 and the No. 3 gear 47 to rotate through the connecting shaft. After the No. 3 gear 47 rotates, it will rotate the scraper 43 to scrape off the residual fog on the top wall of the transparent observation window 2, making the transparent observation window 2 clearer, avoiding the fog from blocking the line of sight, and bringing convenience to use. At the same time, the salt spray resistance test results of the electronic components can be observed in real time without opening the transparent observation window 2 again, thereby ensuring the salt spray resistance test effect of the electronic components.
