Warm tip: 1. Please do not puncture the atomizing sheet of the spray port!!! 2. Please take out the cotton swab before using it for the first time (pay attention to the spring below), soak it in water for 1-2 minutes, and let the cotton swab fully absorb water before installing it. 3. Only tap water or mineral water can be used, but pure water cannot be used (it will affect the fog effect)
