Abstract
For the manual discharge of a pulverulent medium a discharge apparatus (1) has an air pump (9), whose compressed air flow receives the powder medium via an injector (37) and a turbulence chamber (38) from a dosing mechanism (25) automatically refillable from a medium reservoir (4) and is discharged accompanied by acceleration through an outlet channel (21). Thus, with a compact construction and easy handling, the production of an aerosol for inhalation purposes or the like is ensured in simple manner.
Claims43
A media dispenser comprising:
- means for generating a gas flow, said generation means including at least one gas path;
- a medium storage reservoir;
- means for separating a dosed amount of the medium from medium remaining in the reservoir and delivering the dosed amount of medium from said reservoir to the gas flow, which is guided along said at least one gas path;
- and
- means for predepositing said dosed amount of the medium in said at least one gas path and for entraining the amount with the gas flow for common discharge of the amount and the gas flow.
A media dispenser comprising:
- means for generating a gas flow, said generation means including at least one gas path;
- a medium storage reservoir;
- means for delivering the medium from said reservoir to the gas flow, which is guided along said at least one gas path;
- and
- means for separately predepositing a dosed amount of the medium in said at least one gas path and for placing the amount into the gas flow for discharge, said dispenser having an outlet opening for the discharge, wherein a medium dosing mechanism (25) is provided for substantially separating the amount of medium from the medium reservoir prior to said generating means generating the gas flow, wherein said dosing mechanism (25) provides a dosing chamber (26) defined by two chamber parts (27, 28) movable against one another between a filling and a discharge position.
A media dispenser comprising:
- means for generating a gas flow, said generation means including at least one gas path;
- a medium storage reservoir;
- means for delivering the medium from said medium storage to the gas flow, which is guided along said at least one gas path;
- and
- means for primarily separating and predepositing a dosed amount of the medium in a predepositing station of said at least one gas path and for subsequently entraining the predeposited amount of medium with the gas flow for common discharge of the predeposited amount of medium and the gas flow.
A media dispenser comprising:
- means for generating a gas flow, said generation means including at least one gas path;
- a medium storage reservoir;
- means for depositing a dosed amount of the medium substantially separately from medium remaining in the reservoir and delivering the dosed amount of medium from said reservoir to the gas flow, which is guided along said at least one gas path;
- and
- means for predepositing said dosed amount of the medium in said at least one gas path and for entraining the amount with the gas flow for common discharge of the amount and the gas flow.
