An electronic cigarette, comprising a housing and a suction nozzle, the housing provided with a support. The electronic cigarette further comprises a top cover capable of covering an opening of the housing, the suction nozzle is disposed at the top of the top cover, one end of the top cover is connected to the support through a rotating shaft, a clamping rib is disposed at the bottom of the top cover, and a locking mechanism connected to the clamping rib by locking and an elastic mechanism for opening the top cover when the locking mechanism is separated from the clamping rib are also disposed in the housing; the locking mechanism comprises a key handle, a transmission and a first spring, and one end of the key handle is connected to the transmission.

A power transfer system to facilitate the transfer of electrical power between tree trunk sections of an artificial tree is disclosed. The power transfer system can advantageously enable neighboring tree trunk sections to be electrically connected without the need to rotationally align the tree trunk sections. Power distribution subsystems can be partially disposed within the trunk sections. The power distribution subsystems can comprise a male end, a female end, or both. The male ends can have prongs and the female ends can have channels, and the prongs and channels may be positioned outside of the trunk sections. The prongs can be inserted into the channels to electrically connect the power distribution subsystems of neighboring tree trunk sections. The prongs and channels may be configured to engage one another without the need to rotationally align the tree trunk sections.

A device for connecting an electrical fixture with electrical power supply wiring, and for mounting the fixture on a support includes a plug, a socket, and a sensing unit for at least one of wirelessly communicating a sensed condition and wirelessly receiving a signal, with the sensing unit electrically coupled to at least one of the plug and socket. The socket includes a socket body having at least one internal cavity therein with an electrically conductive contact terminal disposed within the cavity for establishing an electrical connection between the electrical power supply wiring and the socket. The plug is rigidly fixed to the fixture and insertable into the socket, with the plug having at least one male connector electrically connected to the fixture and engageable with the contact terminal within the socket to establish a circuit between the electrical fixture and the electrical power wiring. A releasable latch is carried on the combination of the plug and the socket for releasably mounting the fixture on the support.

A support base includes a connector hub having a top end, a bottom end spaced apart from the top end, and a chamber wall extending between the top and bottom ends. The chamber wall defines a chamber within the connector hub. An interface may be positioned in the chamber. The interface is dimensioned such that a support gap is formed between the interface and the chamber wall. The support gap may be dimensioned for receiving a wall of a support structure having a hollow interior into which the interface is received.
