Description

Technical Field

[0001] The utility model relates to the technical field of rain test boxes, in particular to a circulating water spraying structure of a rain test box. Background Art

[0002] The rain test chamber is a device that tests the waterproof performance of items by spraying water on them. For its specific structure, please refer to the patent document with announcement number CN210664892U. Since the sample table is installed in the test area through a longitudinal connecting shaft, the water spraying pipe cannot pass through the connecting shaft, which means that the sample on the sample table can only be sprayed in all directions by reciprocating the water spraying pipe. The reciprocating water spraying pipe requires the motor connected to the water spraying pipe to rotate forward and reverse frequently. Compared with the motor rotating forward all the time, the frequent forward and reverse rotation of the motor will greatly increase the power consumption, which needs to be improved.
