[0032] Working principle: When using this photovoltaic module salt spray chamber, firstly as follows... Figures 1-5 As shown, the user places the photovoltaic module to be tested for salt spray on the grid plate 6. Then, the user rotates and closes the cover plate 2, causing the sealing gasket 3 to adhere to the housing 1. Next, the user rotates the knob 402, causing it to move relative to the limiting plate 401 and insert into the retaining sleeve 5, thus limiting the cover plate 2. The user then pours the salt spray material into the water tank 11. Next, the user inserts the end cap 20 into the water tank 11 and tightens it, sealing the water tank 11. Then, the user starts the dual-head motor 12. The dual-head motor 12 drives the main bevel gear 13 to rotate, simultaneously driving the fan rod 9 to rotate via the sprocket mechanism. At this time, the main bevel gear 13 drives the secondary bevel gear 15 to rotate.

The device is lifted, and then as the wind rod 9 rotates relative to the support arm 8 and the housing 1, the wind rod 9 drives the fan blade 10 to rotate. At this time, the fan blade 10 discharges the air from the circulating air duct 7, so that the air inside the device enters from one end of the circulating air duct 7 and exits from the other end of the circulating air duct 7, thereby completing the circulation of air inside the device. Next, after the salt spray solution is mixed, the user starts the water pump 16, and then the water pump 16 pumps the salt spray solution in the water tank 11 into the atomizing nozzle 18 through the water inlet pipe 19 and the water outlet pipe 17, so that the atomizing nozzle 18 sprays salt spray into the device. At the same time, the salt spray enters the device and circulates with the air, thereby making the salt spray evenly distributed inside the device. At this time, the device conducts a salt spray test on photovoltaic modules. Therefore, the device is good at creating a uniform salt spray environment, thereby ensuring the effect of the salt spray test and improving the practicality of the device.
