A switch mechanism of an electronic cigarette, comprising: a housing (10); a support (20) fixed in the housing; a circuit board (50) fixed in the support, the circuit board (50) being provided with a detection switch (51) for controlling conduction or disconnection of a power supply circuit of the electronic cigarette; a sliding part, the sliding part being in sliding fit with the support (20) and being capable of moving between a position near the detection switch (51) to enable the detection switch (51) to be conducted and a position far away from the detection switch (51) to enable the detection switch (51) to be disconnected in an axial direction of the housing (10), and a part, extending to an outer surface of the housing (10), of the sliding part forming a push button (60); and an elastic element (80) used for providing an elastic stress to enable the sliding part to move to the position far away from the detection switch (51). According to the present invention, under the condition that no larger external forces are applied to the push button (60), the power supply circuit of the electronic cigarette is not conducted, thereby avoiding a wrong operation when the switch mechanism is carried or used. |
