A bathroom management apparatus may include a case having an air suction port formed in an upper portion of a front surface thereof, a first air discharge port formed in a lower portion of the front surface thereof, and a second air discharge port formed in a lower surface thereof. A suction vane opens or closes the air suction port, and first and second discharge vanes opens or closes the first and second air discharge ports, respectively. A duct is provided in the case to connect the air suction port, the first air discharge port and the second air discharge port to one another. A blowing fan is provided in the duct to suck air through the air suction port and blow the air to the first air discharge port and the second air discharge port. A heater heats the air in the duct.

Aspects of the present disclosure include a method of managing scent in an environment, which includes disposing at least one scent diffusion device within an environment, wherein the at least one scent diffusion device comprises a communications facility that enables transmitting signals to and receiving signals from a remote computer, receiving at least one target value of a scent parameter for the environment at the remote computer, and controlling, via the remote computer, diffusion of a liquid from a source of the liquid in fluid communication with the at least one scent diffusion device to achieve the target value of the scent parameter. Controlling a diffusion rate of the liquid includes altering at least one of a voltage and a duty cycle applied to at least one component of the diffusion device.

Methods, systems, and devices are disclosed for implementing switchable dispensing and/or delivery of scented substances. In one aspect, a device includes a cartridge structured to include one or more chambers containing one or more scented substances contained in a corresponding chamber, a housing structured to include a compartment to hold the cartridge, an opening to allow the scented sub stances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to accelerate a scented substance from the corresponding chamber to the opening, and an actuator switch arranged in a corresponding transporting channel and operable to move between an open position and a closed position based on an applied signal to selectively allow passage of the scented substance from the corresponding transporting path.

Electrical connectors and fixtures, and more particularly, electrical plug and socket combinations allowing quick connection and mounting of electrical fixtures are provided with a disinfection feature for disinfecting air and/or surfaces. Additionally, lighting fixtures include or are retrofitted to provide both lighting and disinfection functions. The disinfection feature can be provided by any suitable source of UV radiation, such as an LED array. The emitted UV radiation is UV-A or FAR UV-C so that disinfection can occur regardless of whether a human is exposed to the emitted UV radiation or the emitted UV radiation is UV-C so that disinfection should only occur if there is no human exposure to the emitted UV radiation. Some electrical connectors and fixture can provide both types of emitted UV radiation, which are selectively actuatable.

The present invention relates to an air treatment system (1) comprising a sterilization unit (2) arranged for producing ozone, a photooxidation unit (3) arranged for subjecting an air flow to a photooxidation process, and a control unit (4) arranged for in a first operational mode directing an air flow through the sterilization unit (2), and in a second operational mode directing an air flow through the photooxidation unit (3). By providing an air treatment system (1) which can operate in two different modes i.e. in a photooxidation or a sterilization mode, it is possible to specifically remove the undesirable pollutants in the air, e.g. removing either gas-phase

Various fragrance dispensers are disclosed. The fragrance dispenser can include a core unit that has a connection unit and a control unit. The fragrance dispenser can include a cartridge that is configured to engage with the core unit. The cartridge can include an impeller and a fragrant material. The fragrance dispenser can have a motor that drives the impeller, thereby dispersing the fragrance. The cartridge can be configured to disengage from the connection unit, such as when the cartridge reaches a depleted state.

A light system for suppressing a microbe having a photosensitive defense mechanism, said light system comprising a plurality of light sources comprising at least, a first light source configured for emitting a first light having a first wavelength suitable for photolyzing or otherwise inactivating the microbe; and a second light source configured for emitting a second light having a second wavelength, different from said first wavelength, suitable for disrupting said photosensitive defense mechanism; a controller for selectively powering said plurality of light sources in a plurality of modes to emit emitted light from said light system, said plurality of modes comprises at least a first mode and a second mode, wherein said emitted light is white light in at least one of said first mode or said second mode.

A deodorization treatment apparatus according to an embodiment of the invention includes a deodorant tank housing microorganism-retaining carriers, supplied with odorous gas, and discharging an exhaust gas in which an odor has been removed by the microorganisms, a water sprinkler device, a water tank, a water sprinkler pipe, an exhaust pipe, a first blower, an aeration device, and a control device controlling at least one of blowing amount of the first blower, watering amount or watering frequency of the water sprinkler device, amount of air bubbles generated in liquid of the aeration device, water supply to the water tank, drainage from the water tank, or temperature of the deodorant tank according to measurement results.

An exhaust fan for preventing air pollution includes a main body and at least one gas detection module. The main body is configured to form an airflow-guiding path and includes a gas guider and a filtration and purification component disposed in the airflow-guiding path. The gas guider introduces an air convection for guiding an air pollution source contained in an air to pass through the filtration and purification component so as to filter and purify the air pollution source. The at least one gas detection module is disposed in the airflow-guiding path for detecting the air pollution source and transmitting gas detection data.

Methods, devices and systems are described for digitally creating new scents or digitally dispensing gas, vapor, or liquid substances. A device includes a container or replaceable cartridge including one or more chambers containing one or more scented substances; a housing structured to include a compartment to hold the cartridge, an opening to allow the one or more scented or unscented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to deliver a scented substance from the corresponding chamber to the opening for delivering a scent from the one or more scented substances; and an actuator switch arranged in a corresponding transporting channel and rapidly operable to move between an open position and closed position based on an applied signal to selectively allow passage of the scented or unscented substance from the corresponding transporting path.
