The humidifier includes a humidification section which vaporizes water to produce humidified air, and a fan which produces in an air passage an air flow delivering the humidified air to the outside. The humidifier further includes a sterilized water producing section which produces sterilized water, an ultrasonic irradiator which produces sterilizing mist through ultrasonic irradiation of the sterilized water, an auxiliary passage through which the sterilizing mist is delivered to the outside, and an operation switching mechanism. The operation switching mechanism is switched between a first operation mode in which the air passage and the auxiliary passage communicate with each other to introduce the sterilizing mist into the air passage, and a second operation mode in which communication between the air passage and the auxiliary passage is blocked.

Described herein are systems and techniques for generating odor impressions of scents. Some embodiments provide odor impressions in an extended reality (XR) environment (e.g., virtual reality (VR) and/or augmented reality (AR)). The system determines spatial characteristics of an odor impression that is to be generated in the XR environment. The system generates one or more commands for generating the odor impression based on the spatial characteristics. The system transmits the command(s) to a controller for execution. The controller may control dispersal of scented media to generate the odor impression.

A essential oil diffuser that gasifies a liquid, such as water, which passes through a screen where it picks up essential oil and diffuses it into the ambient air.

A scent delivery system includes scent delivery units that are configured to deliver scent at a variable scent level by being turned on and off successively according to a variable duty cycle. The scent delivery system also includes a central controller configured to control the scent delivery units by generating command data based on a scenting schedule that indicates a desired activation time for more than one scent delivery unit. The scenting schedule is configured to further indicate a scent level bias to be applied to base scent settings that are associated with different scent delivery units. The central controller is configured to generate the command data, based upon a variation in the scent level bias, that takes into account a corresponding variation to duty cycles associated with different scent delivery units and to communicate the command data to the different scent delivery units.
