Due to the presence of the connecting rubber ring 7, a first interlayer space is formed between the first cover plate and the waveguide lens 1, and a second interlayer space is formed between the second cover plate and the waveguide lens 1. In a high temperature and high humidity environment, due to the different internal and external air pressures, water mist is easily generated in the first interlayer space and the second interlayer space.
