A mosquito repeller includes a casing, a mosquito repellent liquid bottle, and a first heating element installed in the casing. The first heating element includes a first heat-generating body and a cotton swab. The first heat-generating body is inserted into the cotton swab, and an end of the cotton swab away from the first heat-generating body extends into the mosquito repellent liquid bottle. Since the first heat-generating body is inserted into the cotton swab, heat is concentrated at the center of the cotton swab, and the cotton swab is heated uniformly, and the vaporization of the mosquito repellent liquid is stable to improve the mosquito repelling effect of the mosquito repeller, while reducing the power consumption of the mosquito repeller, saving energy, avoiding a temperature rise of components near the heat-generating components, retarding the ageing of components, and extending the service life of the mosquito repeller.

A scent dispenser may comprise a vial retaining mechanism, a heating element, vial sensor, and a controller. The vial retaining mechanism includes a vial coupling that removeably retains a vial containing a scented solution. The includes a wick extending from a cavity of the vial through an opening of a neck of the vial. The heating element is shaped to receive and heat the wick of the vial. The vial sensor includes an array of sensor pads that are arranged in alignment with the vial retained by the vial coupling. The controller is electrically coupled to the heating element and electrically coupled to the array of sensor pads. The controller regulates a temperature level of the heating element, and receives signals from the array of sensor pads and processing the signals to determine a fluid level of the vial.

A method for controlling one or more scent delivery units includes maintaining one or more scheduled events, maintaining one or more scheduled anti-events, and generating, based on the one or more scheduled events and the one or more scheduled anti-events, command data to be communicated to the one or more scent delivery units to control their activation and deactivation. Generating the command data includes identifying a conflicting period of time during which control specified by the one or more scheduled events differs from control specified by the one or more scheduled anti-events and also includes generating command data that gives priority to control specified by the one or more scheduled anti-events. Control for the one or more scent delivery units during the conflicting period of time is in accordance with control logic of the one or more scheduled anti-events and not the one or more scheduled events.

An improved portable scent warmer having a modular or compartmentalized housing holding a scented member, a heating element imparting heat to the scented member to release its fragrance, a fan element for direct the dispersion of the fragrance, a input device for selectively controlling and actuating the heating element; a rotatable cover adjoined to the housing; and at least one power supply means for powering the heating element.

An air scenting assembly includes: a scent container which at least initially contains a scent perfume, and a scent perfume extracting mechanism, which is configured to release scent perfume from the scent container. The scent perfume extracting mechanism includes a scent perfume absorbing element insertable into said scent container, a scent carrying material, a dripping mechanism arranged onto said scent perfume absorbing element, said dripping mechanism is configured to deposit scent perfume from the scent container onto said scent carrying material, and a limiter to restrain extraction of scent perfume from the scent container, wherein the limiter comprises an air duct between the scent perfume absorbing element and the dripping mechanism, and the limiter is air flow controlled, wherein one end of said air duct is placed inside said scent container, and wherein the other end of said air duct is connected to a nozzle, said nozzle being arranged on said scent carrying material so that when said scent carrying material is drenched to saturation, no more air can pass through said scent carrying material and up into said nozzle and said air duct, and so that when the scent carrying material is dry enough passage of air through said air duct is allowed.

Methods and systems are provided for improving the operation of a start/stop vehicle having an FEAD-driven AC compressor. During an engine idle-stop, fragrance is dispensed into a vehicle cabin via a fragrance dispensing device integrated with a vent of a vehicle AC unit. The dispensed fragrance masks must smells attributed to an evaporator when the engine is shut-down, thereby extending the duration of idle-stop.

A system and method for application controlled fragrance generation are disclosed. A particular embodiment includes: receiving a fragrance trigger from an application, the fragrance trigger being associated with a particular fragrance that corresponds to an event, action, image, sound, or gesture depicted in the application, determining a temperature needed to cause the particular fragrance to be emitted from a fragrance cartridge; and causing a thermal element to heat the fragrance cartridge to the determined temperature.
