| 摘要 |
The invention relates to a metering device (20) for dispensing a medium to an environment, with a housing (30), a shallow metering chamber (60) within the housing (30), which metering chamber is of planar design and is essentially closed off from the environment by wall sections (40, 50), a first media inlet (60a) which is connected to the metering chamber (60) and can be connected to a media reservoir (12), and a vibration mechanism (40) which is arranged in such a manner that vibrations generated by it cause pulsing changes in volume of an internal volume of the metering chamber (60), wherein a wall section which is designed as an outlet wall section (50) has metering openings (62) by means of which the metering chamber (60) is connected to the environment. According to the invention, the vibration mechanism (40) forms a vibration wall section (40) by means of which the metering chamber (60) is delimited. Use for the discharge of media in mist-like form.
