This invention discloses a band-reconfigurable radio frequency energy harvester unit based on metasurfaces, comprising a first dielectric substrate and a second dielectric substrate, with an air layer between them; a top-layer metal structure is disposed on the upper surface of the first dielectric substrate; a lower microstrip metal structure is disposed on the upper surface of the second dielectric substrate, and a bottom-layer ground metal layer is disposed on the lower surface of the second dielectric substrate; the top-layer metal structure and the lower microstrip metal structure are connected by a conductive metal pillar structure; a metallized via is also disposed in the middle of the second dielectric substrate, penetrating the second dielectric substrate and the bottom-layer ground metal layer. This invention enables the radio frequency energy harvester unit to cover the environmental radio frequency resources as much as possible, improving its radio frequency resource utilization per unit area, enhancing its practicality and robustness, while also having a compact design that meets the self-powering requirements of wireless sensor networks.

This application proposes an electronic atomizing device, including a main housing and a mouthpiece disposed on the main housing; the mouthpiece defines an air outlet; the main housing also defines a first connecting port and a second connecting port; wherein the mouthpiece is movable relative to the main housing to selectively change between a first position, a second position, and a third position; in the first position, the mouthpiece's air outlet is connected to the first connecting port and disconnected from the second connecting port, thereby receiving aerosol output from the first connecting port; in the second position, the mouthpiece's air outlet is connected to both the first and second connecting ports simultaneously, thereby simultaneously receiving aerosol output from both the first and second connecting ports; in the third position, the mouthpiece's air outlet is connected to the second connecting port and disconnected from the first connecting port, thereby receiving aerosol output from the second connecting port. This allows for flexible adjustment of the aerosol receiving method via the mouthpiece, enhancing the diversity of aerosol output.
