摘要： A system for environmental maintenance includes a vacuum unit, an air purifier unit, a controller communicatively connected to the vacuum unit and the air purifier unit, a sweep sensor communicatively connected to the controller, and a movement sensor communicatively connected to the controller. The sweep sensor detects debris swept into a detectable vicinity of the sweep sensor and the controller turns on the vacuum unit upon detection by the sweep sensor. The controller turns on the air purifier unit upon the vacuum unit being turned on, and the air purifier unit cycles on for a period as programmed in the controller. The movement sensor detects movement in detectable vicinity of the movement sensor and the controller turns on the air purifier unit upon detection by the sweep sensor, if the air purifier is not already turned on.

摘要： An air purifier includes a main housing, an air filter, a driving motor, a centrifugal fan, and an air outlet guider. The air outlet guider includes a central hub connected to the driving motor, a plurality of outlet guiding blades outwardly extended from the central hub, and a peripheral rim connected to the central hub at a distance from the central hub to form an air guiding cavity between the central hub and the peripheral rim. The outlet guiding blades extend in the air guiding cavity. When the driving motor is activated to draw air from the air inlet, the air is forced to sequentially pass through the filter assembly and the guiding cavity. The air in the air guiding cavity is diverted and guided by the outlet guiding blades to form a more streamlined flow which is to be discharged through the air outlet.

摘要： A virus elimination assembly for sterilizing air includes a base that is hollow. An intake vent is pivotally coupled to the base to direct air into the base. A canister is coupled to the base and the canister is in fluid communication with an interior of the base. A filter tray is slidably positioned in the canister and a filter is integrated to pass air therethrough. A blower tray is slidably positioned in the canister and a blower is integrated therein to blow air when the blower is turned on. A light tray is slidably positioned in the canister and a light emitter is integrated therein to eliminate viruses and bacteria. An exhaust vent is pivotally integrated into the canister to direct the air that has been sanitized by the light emitter out of the exhaust vent.

摘要： A handheld air purifier may include a suction body provided with a suction surface having a first and second frame, a fan to suction air, and a filter to filter suctioned air, a bending portion extending rearward from the suction body to bend upward, and a handle extending further from the bending portion and held by the user. The second frame may be provided behind the first frame and may include a protrusion that penetrates through the first frame to create a gap between the suction surface and a garment being treated to promote a free airflow through the handheld air purifier.

摘要： Embodiments of the present technology are directed to air treatment reactor modules, and associated systems and devices. An exemplary reactor module can include a housing, an ultraviolet (UV) light source disposed within the housing, and a plurality of hollow elongate conduits disposed within the housing and peripheral to the UV light source. The UV light source and individual conduits can extend in a lateral direction perpendicular to the direction of air flow through the reactor module. The conduits can include a plurality of holes and be at least partially coated with a photocatalytic material. The housing can have an inner surface comprising a reflective material that, in operation, reflects UV light emitted from the UV light source.
