For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in FIGS. 1 to 3 , a portable aromatherapy machine according to an embodiment of the present invention comprises a housing 1, a fan 2, a guide air duct 31, an atomizer 4, a mist outlet channel 51, a control device 6 and a handle 7. The housing 1 comprises an upper chamber 13 and a lower chamber 14, wherein the lower chamber 14 is used to hold liquid; a first air inlet 111 is formed in the cavity wall of the upper chamber 13; the fan 2 is disposed in the upper chamber 13 and configured to inhale airflow from the first air inlet 111 and blow it out; the guide air duct 31 is configured to receive the airflow blown out from the fan 2 and guide it into the lower chamber 14 or to store liquid that flows back into the upper chamber 13 due to tilting; The atomizer 4 is arranged in the lower chamber 14, and is configured to atomize the liquid contained in the lower chamber 14 to form an atomized airflow; the mist outlet channel 51 is configured to receive the atomized airflow in the lower chamber 14 and guide it to the mist outlet 112; the mist outlet 112 is arranged on the shell 1, and is configured to discharge the atomized airflow in the mist outlet channel 51 into the surrounding environment; a first sealing ring 8 is provided at the connection between the mist outlet channel 51 and the mist outlet 112; the control device 6 is arranged in the upper chamber 13, and the fan 2 and the atomizer 4 are electrically connected to the control device 6; the handle 7 is rotatably connected to the shell 1 by loosening the connecting button;

Based on the above structure, when the aromatherapy machine is in normal use, the control device 6 and the liquid are separated in two cavities, thereby avoiding the risk of water ingress to the control device 6; and when the aromatherapy machine is tipped over, the liquid in the lower cavity 14 can be discharged from the shell 1 through the mist outlet 112 via the mist outlet channel 51; or stored in the guide air duct 31, and after the aromatherapy machine is placed flat again, the liquid flows back to the lower cavity 14; thereby avoiding contact between the liquid and the control device 6 in the upper cavity 13, greatly reducing the risk of water ingress to the control device 6, reducing safety hazards, and improving the safety of the aromatherapy machine.

Further, please refer to FIG. 3 , the guide air duct 31 is a curved channel; thus, on the one hand, it can prevent the liquid from flowing directly into the upper cavity 13 through the guide air duct 31 , thereby facilitating the storage of the liquid; on the other hand, it increases the volume of the guide air duct 31 , thereby storing more liquid.

Specifically, a maximum water level line is provided on the inner wall of the lower chamber 14. When in use, the liquid capacity in the lower chamber 14 shall not exceed the maximum water level line. In this way, when the aromatherapy machine is tipped over, the liquid with rated capacity directly flows out from the mist outlet 112 or is stored in the guide air duct 31 and does not flow into the upper chamber 13.

Further, referring to FIG. 2 and FIG. 3 , as a specific embodiment of the portable aromatherapy machine provided by the present invention, it further includes a partition seat 5, and the partition seat 5 is arranged in the housing 1 to divide the internal space of the housing 1 into the upper chamber 13 and the lower chamber 14;
