In this embodiment, the anti-toppling switch may be a mechanical anti-toppling switch or a photoelectric anti-toppling switch.

In view of the above, in this embodiment, firstly, the air pump 2 is controlled to stop working when the atomizing device is toppled over, so that no air flow exists in the air flow channel (including the atomizing channel) of the whole device, and then the air inlet channel and the air outlet channel (or the mist outlet channel) in the atomizing device are respectively blocked by the first anti-toppling structure and the second anti-toppling structure by using the impact and inertia occurring when no air flows through and topples over, so that a part of the atomizing channel of the atomizing device and the internal space of the essential oil container 4 connected to the device form an independent closed space, so that the essential oil in the essential oil container 4 can only flow in the space at most, and cannot overflow the air pump 2 or the atomizing device, thereby achieving the function of preventing the essential oil from overflowing.
