[0003] Chinese patent CN118500558A discloses a temperature testing device for hair dryer production. It includes a testing platform and a hair dryer. A limiting frame matching the hair dryer is detachably connected to one side of the testing platform. A positioning fixture matching the hair dryer is suspended on the testing platform. The hair dryer is horizontally limited on the limiting frame by the clamping of the positioning fixture. The hair dryer has an air outlet. A temperature testing panel corresponding to the air outlet is located on the other side of the testing platform. The temperature testing panel can slide and be fixed on the testing platform.

[0062] This novel experimental device allows for adjustment of the testing height of the hair dryer.
