[0002] As the name implies, the rain test chamber is a test equipment that simulates a rainy environment to test products. It is mainly used to assess whether the housings and seals of electrical and electronic products can ensure the good working performance and technical status of the equipment and components after or during the water test. At the same time, the product may be affected by water during transportation or use, providing a reference basis for product technical standards.

[0003] In the prior art, patent number: CN219773080U discloses a water supply flow control device for a rain test box, including a test box body, a water supply assembly is arranged on the top of the inner cavity of the test box body, and the tested product can be fully sprayed with water through the cooperation of a water pump, a four-way pipe, a water pipe and a connecting ring. Through the cooperation of a reduction motor, a first rotating shaft, a second rotating shaft, a driving gear, a driven wheel and a rotating plate, the user can complete the flow control of the three water pipes by turning on the reduction motor, which is convenient for the user to adjust the rain intensity. The adjustment can be completed without replacing the nozzle, saving time and effort. The user turns on the reduction motor, and the reduction motor drives the first rotating shaft to rotate, and the first rotating shaft drives the driving gear to rotate, so that the driving gear drives the driven gear to rotate, and then the driven gear drives the second rotating shaft to rotate. At this time, the first rotating shaft and the second rotating shaft drive the rotating plate to rotate.

[0004] Although the above-mentioned rain test box can adjust the water supply to achieve the purpose of adjusting the rain intensity, it still has the following shortcomings in practical applications: the angles of the nozzle and the connecting pipe are fixed and cannot be adjusted to different angles, resulting in inaccurate test results.
