The invention discloses an anti-
backflow atomization device, and relates to the field of atomization equipment. The atomization device comprises a shell, a liquid containing
bottle, an atomization
nozzle, an atomization shell and an
air pump. The shell is provided with a mist outlet; the liquid containing
bottle is arranged in the shell and used for containing liquid. The atomizing
nozzle is arranged in the shell; the atomizing shell is connected between the liquid containing
bottle and the mist outlet and is wound outside the atomizing
nozzle; the atomizing shell comprises a flow guide
pipe extending into the liquid containing bottle, the atomizing nozzle is communicated with the flow guide
pipe, and a gap is formed between the
peripheral side of the flow guide
pipe and a bottle opening of the liquid containing bottle. The atomization shell is provided with an anti-
backflow cavity communicated with the gap, and the anti-
backflow cavity is used for temporarily storing at least part of liquid in the liquid containing bottle when the shell is inverted; the
air pump is arranged in the shell and communicated with the atomizing nozzle. According to the anti-backflow atomization device, through the arrangement of the anti-backflow cavity, at least part of liquid in the liquid containing bottle can be temporarily stored when the shell is inverted, so that the liquid is not prone to backflow from the flow guide pipe, the problem that the liquid flows out of the shell can be solved, and the use experience of a user is improved.
