A microstructured passage module for aerosolizer is disclosed. The module includes a plate overlaid by a cover, an entrance, an exit, a plurality of protrusions and a plurality of pillars. The protrusions and pillars project from and are integral parts of the plate. Further, the plate can be divided into a first zone proximate to the entrance and a second zone proximate to the exit. The protrusions are arranged into parallel rows in a direction from the entrance to the exit and form parallel passages therebetween in the first zone for the liquid to flow along. The protrusions in each column are spaced from one another by tunnels. The pillars are interposingly disposed in the second zone and define certain channels therebetween. Moreover, a plurality of pillars further disposed in the passages increase a flow resistance for the liquid flowing through the passages.

A nebulizer is proposed which includes an insertable container and a securing mechanism for holding the container in the nebulizer such that the container can move back and forth but can not be separated. The securing mechanism is formed by a metal unitary part. The securing mechanism forms a transportation lock for holding the container unmovable in the housing in a delivery state of the nebulizer. The securing mechanism forms a ring with flexible holding fingers.

An automatic extraction device and connector for perfume decanting are disclosed. In this automatic extraction device, the front end of the piston cylinder is formed with a nozzle. The piston extends into the cavity of the piston cylinder. A press piece is mounted at the rear end of the piston rod and extends to the outside of the piston cylinder. A liner is fixedly provided inside the piston cylinder. The front end of the piston rod passes through the liner and is fixedly connected with the piston. The space between the liner and the nozzle inside the piston cylinder forms the compression space of the piston. The thrust produced by the compression spring on the piston rod drives the piston to have a tendency to move away from the nozzle.

The invention relates to the field of inhalation devices for liquids. In particular, the invention relates to a liquid emission mechanism for an inhalation device, as well as a method of emitting a liquid from an inhalation device.

The inhalation device comprises a housing (1), a reservoir (2) for storing a liquid, a pumping unit, said unit comprising a riser pipe (5), a hollow cylindrical part (3) having an interior space and being linearly moveable on the riser pipe (5), wherein the pumping chamber is fluidically connected with the reservoir (2), and a nozzle (6) which is connected liquid-tight to an downstream end portion (5B) of the riser pipe (5), and wherein said linear relative motion can be effected by a relative rotation around a rotational axis (R) of a rotatable part (1A) with respect to a counterpart (1B), such that said relative rotation is converted into said linear relative motion by means of a gear mechanism comprising at least one cam surface having a first section (9A) and a second section (9B), and wherein a means for the storage of potential energy (7) is provided.
