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 scent distribution device having a spherical housing and having one or more internal cavities in communication with a plurality of wicking members. The wicking members dispersed across the exterior of the housing for the distribution of a scent agent. The device including a harness engaged with an axis of the housing, wherein the housing rotates along the axis for rolling across a surface. The device further including a lead line and segregated and compartmentalized storage container.

An ultraviolet air sanitizer apparatus for HVAC systems has a frame defining a flow passage therethrough configured such that the frame rear is insertable into a return air inlet of the HVAC system. A sanitizer light is disposed within the flow passage. When activated, the sanitizer light emits germicidal ultraviolet light into the surrounding flow passage. A light baffle is disposed within the flow passage upstream of the sanitizer light and allows air flow but blocks light. An air pressure sensing switch is electrically connected to the sanitizing light and configured to measure air pressure differential across an air filter. When the air pressure differential is a predetermined value or greater, which is indicative of air circulation by the HVAC system, the switch turns on the sanitizer light. When the pressure differential is less than the predetermined value, the switch turns off the sanitizer light.

An intelligent induction atomizer comprises a main shell and a bottom shell detachably mounted at the lower end of the main shell. A bottle container, a middle baffle and a control mainboard are arranged in the main shell. The atomizer can be used for sterilization by means of infrared inductive atomization, and adopts the battery to supply power, thereby being convenient and safe to use; and multiple purposes can be fulfilled by adding or changing liquid in the bottle container.

Device (145) for dispensing drops of liquid, characterised in that it comprises: —at least one container (100) for a liquid, comprising at least one internal chamber and an upper opening, each chamber having a lower aperture and a seal sealing the upper opening, the seal having a substantially planar resiliently deformabie flexible portion, —at least one mechanical actuation means (146) configured to deform a flexible portion of a seal of at least one container, —a means (147) for selecting the volume of a drop to be dispensed from a plurality of drop volumes, a means (148) for determining the volume of liquid present in at least one container, and—a means (149) for controlling the actuation means, which means controls the movement from at least one point of the flexible portion of a container seal, as a non-constant function of the drop volume to be dispensed and the volume of liquid present in the container.

This invention provides an air disinfecting device for disinfecting or decontaminate air, which comprises a first metal plate and a second metal plate opposite to the first metal plate, a UVC LED mounted on the first metal plate, and a power supply providing power to the UVC LED. The second metal plate has an area large enough such that lights emitted from the UVC LED will be enclosed inside the air disinfection device.

An essential oil reflux-type atomizer comprising the following structures: chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. The filter atomization mechanism is installed in the housing and has an upper filter and a lower filter. The essential oil atomizer can be improved efficiency and reduced noise level.

The present invention relates to an herbal or sage extract composition for producing aroma without the need to burn the herb. The composition is in the form of an aerosol or a solid air freshener soaked in herbal solution. More specifically, the composition includes an herb such as sage extract that can be in the form of one of oil or powder, a propellant, an active ingredient and an organic solvent. The aerosol solution is sprayed on a surface and releases the herbal or sage aroma that helps in creating positive ambience and helps clearing negative energy. The composition can be used with an aerosol device and allows for a safer and more convenient way to produce the aroma.

A modified liquid electrical vaporiser is disclosed with a modified chimney that provides enhanced distribution of actives.
