Patent number: 11534520Abstract: A device has a container for a substance to be dispensed. A wick as a capillary element in contact with the substance in the container and forms part of the container. The wick has a wick-side substance dispensing area. A heating element produces a substance air flow, which is enriched with substance and flows away from the device, by heating the wick-side substance dispensing area and a substantially substance-free hot air flow that flows away from the device and is warmer than the substance air flow, by heating the air surrounding the heating element. A flow-guiding and/or deflecting apparatus guides and/or deflects at least one of the air flows, preferably the substance-free hot air flow, such that the air flows hit each other, preferably at a defined angle of incidence, and form a common substance-and-hot-air flow flowing away from the device.Type: GrantFiled: June 16, 2016Date of Patent: December 27, 2022Assignee: CTR, LDAInventors: David Dycher, Pedro Queiroz Vieira

Publication number: 20220072180Abstract: Volatile substances are evaporated from a substance container via wick inserted into the container. A wick end region protrudes from the container. A heating device has a heating body with a wick recess, forming an air flow channel with an inlet and outlet opening. The wick end region can be received under air flow around it with a circumferential gap spacing from the wick recess wall region. A penetration depth of the wick end region into the wick recess is adjustable. The wick recess has a throttling segment with a reduced flow cross section, situated above the wick end region when the wick end region protrudes into the wick recess. The position of a free wick end is adjustable relative to the throttling segment to adjust the air mass flow through the wick recess and/or the flow velocity of the substance-laden substance air flow.Type: ApplicationFiled: December 14, 2018Publication date: March 10, 2022Inventors: DAVID DYCHER, PEDRO QUEIROZ VIEIRA
