In some embodiments, since the electrical connection valve 50 is provided between the power supply assembly 200 and the atomizing device 100 , the user can set the electrical connection valve 50 to a closed state during storage of the aerosol generating device. Even if a child or minor touches the aerosol generating device and performs imitative pressing or touching operations without supervision, the aerosol generating device cannot be triggered to work. In some embodiments, when the aerosol generating device is stored, the user can set the electrical connection valve 50 to a closed state, even if children or minors come into contact with the aerosol generating device without supervision, Performing imitative suction actions cannot trigger the aerosol generating device to work.

It should be noted that the preferred embodiments of the application are given in the description of the application and its drawings, but they are not limited to the embodiments described in the description. Further, for those of ordinary skill in the art, they can Improvements or transformations are made according to the above description, and all these improvements and transformations shall fall within the scope of protection of the appended claims of the present application.
