The electrical module 500 further includes a liquid level probe 540, the liquid level probe 540 is electrically connected to the circuit board 530, the liquid level probe 540 is connected to the supporting section 240 and inserted into the liquid medicine cavity 210 through the supporting section 240, the liquid level probe 540 should be located at a lower position of the supporting section 240, after liquid medicine flows into the liquid medicine cavity 210, the liquid medicine is used as a medium for connecting the atomizing sheet 310 and the liquid level probe 540, so that the atomizing sheet 310 forms a passage with the circuit board 530 through the liquid level probe 540, and the atomizing sheet 310 can continuously atomize; when the liquid medicine is used up, the path between the atomizing plate 310 and the liquid level probe 540 is cut off, the atomizing plate 310 stops atomizing, and the atomizing plate 310 is prevented from being damaged by dry burning.

The electrical module 500 further includes a data interface 550, the data interface 550 is mounted at the bottom of the housing 110, the data interface 550 is electrically connected to the circuit board 530, and an external wire can be connected to the data interface 550 to charge the battery 510. The data interface 550 may be a type-C, USB interface or the like. The bottom of the housing 110 is provided with a plug hole 112, an external wire is inserted into the data interface 550 through the plug hole 112, an interface plug 113 is inserted into the plug hole 112, the plug hole 112 can be plugged by the interface plug 113, the plug hole 112 is sealed, and waterproof and dustproof effects are achieved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
