ABSTRACT:
An accumulator type, rechargeable atomizing spray mechanism having a container for the liquid to be atomized, and further having an atomizer body, an atomizer head, an engaging and piston member having a large-diameter rod portion. The atomizer head is arranged to cooperate with skirt-like small-diameter, intermediate-diameter and large-diameter pistons formed at a piston member. The large-diameter rod portion of the engaging and piston member forms an exhaust valve with the conical valve body projected at the top thereof and with the exhaust valve hole of the large-diameter cylinder of the atomizer head, and the small-diameter rod-like valve body of the engaging and piston member forms a suction valve with the suction valve hole and a ball valve at the lower portion of the atomizer body.
All the pistons are respectively telescopically inserted into the large-diameter cylinder, the cylindrical guide portion and the small-diameter cylindrical portion of the atomizer body. A gas is formed between the large-diameter rod portion and the small-diameter cylindrical guide to communicate the small-diameter cylindrical portion with the exhaust valve hole of said atomizer head. Since the engaging and piston member is solely formed, this atomizer can be simplified in construction.
