The housing 131 is provided with an inlet hole 1311 and an outlet hole 1312. The housing 131 is provided with an air inlet 1311 communicating with the air inlet 14 provided in the casing 12, and an air outlet 1312 communicating with the first installation space 101. The intake section 161 is formed between an intake hole 1311 and an exhaust hole 1312. Specifically, one side of the housing 131 facing the bottom plate 113 is provided with an air outlet 1312, and the bottom plate 113 is correspondingly provided with an air guide groove 1130. One end of the air guide groove 1130 is communicated with the air outlet hole 1312, and the other end of the air guide groove 1130 is communicated with the first mounting vacant site 101. When the first cartridge 98 is installed in the first installation vacancy 101, the air guide groove 1130 faces the internal air path of the first cartridge 98. The ambient air enters from the air inlet 14, passes through the air inlet hole 1311, flows through the air inlet section 161, and enters the first atomizing air passage 980 through the air outlet hole 1312 and the cartridge air inlet 203 in sequence.
