Abstract: A piezoelectrically operated dispenser dispenses a liquid substance and has a housing and a container in which the substance is received. The container has a neck by which the container is detachably connectable to the housing. The dispenser contains a piezoelectrically operated atomizer system having a piezo element and a wick. The housing has a bottom wall which has a mounting dome which extends upwards and forms a mounting opening. The mounting opening merges into a wick opening at the end of the mounting dome, which is adjoined by the piezo element and also by a housing outlet opening. The mounting dome receives the neck of the container, which is introduced into the mounting dome via the mounting opening, and holds it releasably in the mounting dome by a holding device such that the wick extends with its free wick end through the wick opening and adjoins the piezo element.

Abstract: A device for dispensing, in particular for vaporizing, volatile substances, in particular fragrances and/or active substances, has a housing with an outflow opening for a substance hot-air flow generated in the housing, a flow guiding device provided in the region of the outflow opening, which is configured to direct the substance hot-air flow flowing out of the outflow opening in a predetermined direction and to generate a directed plume. The device preferably has an electrical heating device with a heating element for generating the substance hot-air flow. The flow guiding device for directional deflection of the plume has a deflection surface pointing in the direction of a deflection in the region of the outflow opening, preferably at a distance therefrom, by way of which the plume can be deflected, in particular by a Coanda effect.

Abstract: A device for dispensing and/or diffusing volatile substances has a storage tank for a substance to be released into the environment, an electric heating device, and a delivery engine coupled to the heating device. The delivery engine has a substance-receiving area which is in fluid communication with the substance received in the storage tank. The substance is conveyable from the substance-receiving area to a substance-discharging area of the delivery engine, at which the substance is discharged into an air stream to generate a substance air stream enriched with the substance. A controller actuates the electric heating device and/or an air flow generation device during operation of the device. The electric heating device forms a structural unit in the form of a pod heater and has at least the storage tank, the electric heating element and the delivery engine.
