The invention provides a cigarette outlet and igniting structure of an automatic cigarette case of an electronic cigarette lighter. The cigarette outlet and igniting structure comprises a cigarette case body, a partition plate is arranged in the cigarette case body, the cigarette case body is divided into a cigarette storing region and an igniter installing region through the partition plate and comprises a cigarette supplying assembly, a cigarette outlet mechanism and an igniting mechanism, and relative displacement motion exists between the cigarette outlet mechanism and the partition plate; a sliding groove is formed in the cigarette case body and provided with an igniting hole, the cigarette case body further comprises a sliding piece and a pushing knob, elastic recovery force exists between the sliding piece and the cigarette outlet mechanism and exists between the sliding piece and the cigarette case body, a pushing knob sliding groove is formed in the sliding piece, and the pushing knob is arranged on the pushing knob sliding groove. Compared with a traditional single-function cigarette case and an igniter, the cigarette outlet and igniting structure of the automatic cigarette case of an electronic cigarette lighter is more convenient to use, the needed functions are achieved by using elastic force of the elastic device, and the cigarette outlet and igniting structure is compact in structure, dual-purpose and practical.
