Atomizer utilizing a plurality of cylinder groups to separate air inlet from air outlet

The utility model relates to an atomizer utilizing a plurality of cylinder groups to separate an air inlet from an air outlet. The inside of the atomizer comprises a first cylinder group and a second cylinder group, wherein the first cylinder group comprises a first air inlet opening, and the second cylinder group comprises a second air inlet opening. The first air inlet opening and the second air inlet opening are communicated with the air inlet and the air outlet of the atomizer respectively through connection pipes. The air inlet and the air outlet of the atomizer are structures which are independent and are not communicated due to the fact that the first air inlet opening and the second air inlet opening are from different cylinder groups, cross infection is avoided, and the atomizer can be used safely.
