A capsule for a volatile substance distribution system includes a housing having a first end and a second end and that defines a longitudinal axis that extends between the first end and the second end. The capsule also includes an inlet port disposed proximate the first end and an outlet port disposed proximate the second end. Additionally, the capsule includes a volatile substance member within the housing. The first end is configured to be removably supported by a base unit with the inlet port fluidly connecting with an air outlet of the base unit for receiving an airflow from the air outlet that moves into the housing and across the volatile substance member as the airflow flows from the inlet port to the outlet port. The inlet port is defined by a tapered inlet surface that directs the airflow radially with respect to the longitudinal axis.

A vehicle includes a lock device, a gas generator, an air conditioner, and an ECU. The gas generator generates, in a vehicle compartment of the vehicle, a gas having a sterilizing effect or a deodorizing effect. The air conditioner ventilates the vehicle compartment. The ECU starts operation of the gas generator when a request for operation of the gas generator is made and the door is in the locked state, starts ventilation by the air conditioner after the gas generator is stopped, and keeps the door in the locked state when a request to switch from the locked state to the unlocked state is made during a period from start of the operation of the gas generator to end of the ventilation by the air conditioner.

A system for generating mist includes a vehicle with ventilation system, a misting device configured to atomized fluid to generate a variable amount of mist, and a fan configured to move the variable amount of mist through the ventilation system. The system further includes a particle sensor configured to measure particles and a controller in communication with the particle sensor, misting device, and fan, configured to receive a particle concentration from the particle sensor, compare it to a threshold, and control the variable amount of mist and/or the fan to keep the particle concentration greater than the threshold. A method for controlling mist in a vehicle includes pumping fluid to a misting device, generating a mist of fluid, pumping the mist into a vehicle ventilation system, measuring a particle concentration, and manipulating a misting device, pump, and/or fan using a controller to keep the particle concentration above a threshold.

Embodiments generally relate to a cartridge and a system for scent dispensing and a vehicle comprising a scent dispensing system. In particular, embodiments relate to a concept for a scent dispensing cartridge. A replaceable cartridge for a scent dispensing system comprises one or more chambers for storing scent media, a chamber having an air inlet and an air outlet that allows air to flow through the chamber; and one or more valves to prevent air from flowing through the one or more chambers.

The present invention is a hand sanitizer, air purification, fogger vehicle mount, or combination thereof, attach to a dashboard of a vehicle. Its purpose is to maximize disinfecting opportunities as a countermeasure to the spread of disease, including COVID-19. As a hand sanitizer, this invention is a hand-free device that minimizes cross-contamination among vehicle patrons during operation. A sensor, activated by hand proximity, sends a signal to a controller, then to a pump to dispense a portion-controlled volume of hand sanitizer. To disinfect airborne antigens, HEPA filtration and UV light are utilized. Pathogen lingering on surfaces are disinfected by a fogger, which dispenses atomized droplets throughout a vehicle. To eliminate exposure to nebulized sanitizer, the controller may receive a wireless signal from outside the vehicle. Independently powered, a vehicle can be sanitized each time it arrives at a destination, made ready to transport the next group of patrons safely.

Disclosed herein is a photocatalytic oxidation device configured for integration within a vehicle ventilation system. The device includes a frame, an ultraviolet lamp, and a cell coated with a photocatalytic material. The lamp, when activated, causes the generation of oxidizers at the cell panel. Air is passable through apertures of the cell panel and thus may be moved through the device. The device is structurally configured and dimensionally optimized to provide effective photocatalytic activity within the vehicle ventilation system without overly restricting airflow.

A fragrance system for a room, building or other environment, the system including (a) a stand or other form of base and (b) one or more portable fragrance objects, each portable fragrance object providing a fragrance and configured to rest on the stand or base. The stand or base includes one or more fans or other air movement system arranged to release fragrance from one or more of the fragrance objects.

An automobile air freshening system includes a housing with a forced air mechanism installed in-line within the cabin ventilation system of an automobile. The system is in electrical communication with the battery of the automobile and possess a dedicated fuse. The system is operated by a switch mounted within the dashboard of the automobile and switch located on the housing. There are multiple locations for the application of user-selected air freshener devices capable of being installed within the housing.

In particular, embodiments relate to a concept for a scent dispensing cartridge. A replaceable cartridge for a scent dispensing system comprises one or more chambers for storing scent media, a chamber having an air inlet and an air outlet that allows air to flow through the chamber; and one or more valves to prevent air from flowing through the one or more chambers.

An air freshener has a carrier with a pair of tabs defining a gap. A center tab extends from the pair of tabs and defines a longitudinal axis. At least one scented body is carried by one of the pair of tabs. The pair of tabs and the at least one scented body extend laterally with respect to the longitudinal axis of the center tab in opposite directions. The pair of tabs and the at least one scented body have a lateral width greater than a longitudinal depth.
