Abstract

The utility model relates to a self-automatic atomizer structure. An inflator is connected with one side of the discharge pipe of the atomizer in a way of integrating to contain a piston push rod provided with a handle and a spring in the center. Moreover, a fixing plate is arranged above the atomizer to cooperate with an elastic gasket. The upper side and the lower side of the discharge pipe are equipped with an outer thread section and a through-pipe respectively to communicate with the inflator. The through-pipe cooperates with an air release valve. A plurality of quads are arranged convexly at the lower end of the inflator. The quads and the sieve sleeves provided with notches and slideways are embedded and locked mutually. A leaking-stop ring is arranged under the quads and is closely pasted on the interior wall of the sieve sleeve. The interior wall and the exterior wall of the upper end are equipped with an outer thread section and a stage retaining edge respectively, so a cap and a leaking stop gasket, which are arranged on the a leaking stop ring under the spring of the piston push rod, are fit and locked mutually. Moreover, a closed cover set provided with a retaining seat, a connecting nozzle and a conduit is arranged at a discharge pipe and is locked by a lock ring provided with an inner screw-threads. Thus, with the integrated design of the discharge pipe and the inflator, the manufacture cost and the material cost can be omitted, and the assembling becomes quicker and more convenient.
