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

Publication number: 20190117816Abstract: A device for the release, in particular for evaporation, of volatile substances such as fragrances or active substances, has a container for a substance to be released. At least one wick as a capillary element is in contact with the substance to be released and at least partially in the receptacle and has a substance release region. The wick, preferably its substance release region, is assigned a heating element, preferably an electrical heating element. The wick is assigned a squeezing device with a squeezing element, by which a squeezing region of the wick can be subjected to a squeezing force and/or can be compressed, in particular for a defined short period of time and/or temporarily. A defined amount of substance, in particular at least the substance collected in the squeezing region, can be conveyed with a boost in the direction of the substance release region.Type: ApplicationFiled: June 16, 2016Publication date: April 25, 2019Inventor: DAVID DYCHER

Publication number: 20120073849Abstract: A vibratory appliance includes a tool driven to oscillate by a rotary electric motor. A shaft supported, at an intermediate portion by a pivot, is driven by an orbital drive mechanism. The orbital drive mechanism includes a rotor rotated about a rotor axis by the motor, an elongate part, and a coupler. The elongate part and the coupler are each fixed to a respective one of the inner end and the rotor. The elongate part and the coupler are mutually connected for sliding movement relative to one another, between first and second relative positions in which the inner end orbits about the rotor axis at first and second orbital radii, respectively, to vary the amplitude of oscillation of the tool.Type: ApplicationFiled: September 28, 2011Publication date: March 29, 2012Applicant: HAYCO MANUFACTURING LIMITEDInventors: Bengt IVARSSON, Bettina LEINWEBER, Hei Wai CHOI, David DYCHER, Greg SPOONER, Hoss VONG, James MACKINTOSH, Yee Wah LAM, Teruo HISHIKI
