The upper cover 1623 is provided with a second connecting strip 1620 arranged in the same direction as the first connecting strip 161, and a second air outlet 1625 is formed between two adjacent second connecting strips 1620. When the purified air flows out of the first air outlet 163 and passes through the second air outlet 1625, the flow of the emitted fragrance is driven, so that the air is filled with fragrance, thereby improving the quality of life.
