An ozone treatment system which is usable in enclosed or confined spaces for the inactivation of pathogens such as bacteria and viruses in these spaces.

An odor control system for landfills includes a vapor device configured to generate an odor neutralizing chemical mixture, and at least one fan directed at a working face of a landfill. The at least one fan includes a fan housing having an inlet opening and a discharge opening connected by a passageway therethrough, a blade assembly positioned within the passageway of the fan housing and configured to rotate to generate an airflow from the discharge opening in a first direction, and a motor coupled to the blade assembly. The system includes at least one nozzle in fluid communication with the vapor device and proximate the discharge opening. The at least one nozzle is configured to disperse an odor neutralizing chemical vapor in the same first direction of the airflow from the discharge opening.

A hand wash cleaning and environmental purification diffuser includes tank cover covered on a slot of a water tank in a bottom shell, a diffusing cover assembled to an opening of the bottom shell to shield the tank cover, an air flow channel formed in the oscillation space in the water tank and shaped like a tubular bulge so that when the diffuser is dumped, the liquid in the water tank is less likely to seep directly into the interior of the diffuser or the environment, two oscillators mounted in the oscillation space in the water tank and respectively coated with a layer of acid and alkali resistant coating, users can add safe cleaning liquids such as alkaline ionized water to the oscillation space and atomize into a cleaning mist, which can be used as deodorization and sterilization for hand cleaning, disinfection and environmental purification, and is safe to use.

Methods, systems, and devices relating to an electronic scented candle that is convenient to use and enables rapid generation and dissipation of scented materials are described. One electronic candle device includes a shell that has a through hole, a flame element protruding through the through hole, an installation lid including a locking base to allow removable coupling of a fragrance container, a scent chamber including a locking clip, a first channel, a second channel, a third channel, and a fourth channel. The scent chamber is removably coupled to the locking base by the locking clip, and an air pump provided to supply pressurized air.

A volatile material atomizing device comprises a housing having a fan, a fluid outlet, a plurality of air inlets and a plurality of air outlets. The plurality of air outlets are positioned at least partially around the fluid outlet. A fluid reservoir includes a wick and containing a volatile material. The fluid reservoir is disposed within the housing. An atomizing assembly is in fluid communication with the wick and positioned in the housing. The atomizing assembly is configured to dispense the volatile material out of the fluid outlet.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

A scent masking device for masking a person's body scent while hunting or performing other outdoor activities related to tracking wildlife. The device includes a portable housing having a plurality of air vents, a power supply designed to provide electrical energy to a control panel, an ozone generator, and a fan. The ozone generator is designed to produce ozone when a charge is applied to a plurality of insulated electrode plates coated with trace amounts of conductive materials exposed to atmospheric gases. The fan is designed to expel the generated ozone through at least one of the plurality of air vents outward and away from the hunter, such that the hunter's scent is masked by the expelled ozone within the immediately surrounding region.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

An olfactory environment management system includes a plurality of odor sensors, an aroma diffusing device, and a control server. Each of the plurality of odor sensors detects a chemical substance and determines a detected concentration of the chemical substance. The aroma diffusing device is equipped with first to n-th aroma capsules selected among a plurality of aroma capsules. The control server controls a combination of scents diffused from the aroma diffusing device. The aroma diffusing device determines an epicenter concentration of the chemical substance based on the detected concentration received from each of the plurality of odor sensors and transmits an identity of the chemical substance and the epicenter concentration to the control server. The control server individually controls an intensity of the emission of the aromatic substance of each of the first to n-th aroma capsules based on the identity of the chemical substance and the epicenter concentration.

A volatile material dispenser includes a base and a stand assembly that is coupled with the base. The base includes a fan and a battery therein. The stand assembly includes a platform, a stand that extends from the platform, and a manifold that extends from the stand. The volatile material dispenser also includes a shroud and an air deflector. The shroud is positioned on the base and defines a chimney. The air deflector is positioned between the shroud and the manifold. The air deflector is configured to direct air out of the chimney.
