The utility model is a kind of odor diffusion device that can spread essential oil atomisation, it include an air compressor machine, the control device that more than one connects the essential oil atomization device of the air compressor machine, a confluence connects the atomization pipeline of each essential oil atomization device and one is electrically connected the air compressor machine and each essential oil atomization device. The pressure-air output that the utility model exports air compressor machine is by each essential oil atomization device by smell essential oil atomisation, the majority delivery outlet for being flowed to output pipe again is distributed, the smell essential oil amount that can be distributed is big and in extensive range, it is very suitable to the odor dispersion requirement in large-scale place, and manipulation variation can be carried out using emissioning time, flow and fragrance combination of the control device to each essential oil atomization device, improve the practicability and variability of odor diffusion device.本新型為一種能夠將精油霧化擴散的氣味散發裝置，包括有一空壓機、一個以上連接該空壓機的精油霧化裝置、一匯流連接各精油霧化裝置的霧化管路，以及一電連接該空壓機及各精油霧化裝置的控制裝置。本新型將空壓機輸出的高壓空氣輸出通過各精油霧化裝置將氣味精油霧化，再匯流到輸出管路的多數個輸出口進行散發，可以散發的氣味精油量大且範圍廣泛，非常適合大型場所的氣味散發要求，並且能夠利用控制裝置對各精油霧化裝置的散發時間、流量及氣味組合進行操控變化，提高氣味散發裝置的實用性及變化性。
