Specifically, the high-temperature treatment conditions that the safety helmet needs to undergo are 50°C ± 2°C. This treatment is to simulate the high-temperature environment that the safety helmet may encounter during actual use to test its performance under high-temperature conditions. Through such pretreatment, it can be ensured that the safety helmet can maintain good protective performance under high-temperature conditions during actual use and effectively protect the head safety of the wearer; the treatment devices in the prior art usually need to place the safety helmet inside the treatment box, and the high temperature on the inner wall of the high-temperature treatment box is likely to cause scalds to people's hands, with relatively large safety hazards.
