Disclosed herein is a wearable personal, humidifier that includes a reservoir for holding water including an output port, a water delivery material including a hydrophilic porous or hydrophilic fibrous material, wherein the water delivery material is configured to make an airtight seal with the output port of the reservoir. The water delivery material includes a cavity having an opening to the output port of the reservoir. The output port is located on the bottom of the reservoir when the wearable personal humidifier is worn such that the flow of water from the reservoir to the water delivery material is self-regulated. As a user breathes, water from the water delivery material evaporates into the air consumed by the user and water from the reservoir automatically re-saturates the water delivery material.

Disclosed herein is a humidifier including an improved structure of a water collection tank. The humidifier includes a main body, a water supply tank provided in an upper portion of the main body, a humidifying fabric arranged in an inside of the main body and disposed below the water supply tank to receive water, a fan configured to move air through the humidifying fabric, a water collection tank configured to collect water from the humidifying fabric, a pump configured to pump water from the water collection tank to the water supply tank, and a humidifier lower cover coupleable to and decoupleable from a lower end of the main body. The water collection tank includes a water collection tank top cover provided in an upper portion of the water collection tank, and a water collection tank lower cover configured to be accessible through the lower end of the main body.

A fragrance dispensing system for an aircraft that includes a fuselage defining a cabin interior and an environmental control system (ECS). The ECS includes a source of air that moves air between the source of air and the cabin interior along an airflow path, a mixer unit in airflow communication with the source of air and positioned downstream from the source of air in the airflow path, at least a first air duct positioned in the airflow path between the mixer unit and the cabin interior, and a fragrance dispensing unit positioned between the air source and the cabin interior along the airflow path. The fragrance dispensing unit is configured to dispense at least a first fragrance into the airflow path.

A wicking evaporative humidifier in which cartridge that includes a pad is inserted directly into an air flow through the wall of a duct that distributes conditioned air throughout a structure. A portion of the cartridge may be inserted into a tray filled with water, which may use capillary forces to wick water through the cartridge to the area of the cartridge that is inserted through the duct and within the air flow. Air passing through duct and through and around the cartridge pad evaporates the moisture wicked into the pad and distributes the moisture throughout the structure.

A system for dissolving gases in water comprises a mixing chamber that holds gas and a container in fluid communication with the mixing chamber. In operation, the mixing chamber is flooded to purge the ambient air. A gas delivery system introduces gas into the mixing chamber to push the water out. A pump then pumps temperature and salinity-treated water into the mixing chamber, and a distributor sprays or disperses the water into the mixing chamber. An optional impingement plate and/or mixing medium trap gas bubbles and hold gas-saturated water within the mixing chamber. This produces a volume of substantially bubble-free, highly-saturated gas-infused water that is then released into the container to mix with the water contained therein. This system can be incorporated in aquariums, ice chests, buckets, and live wells found on boats, kayaks, trucks, and other transports.

An oil fan diffuser having a housing with a first section and a second section. A power source such as a plurality of batteries are disposed within the second section. Disposed within the first section is a fan, an inner housing, a fragrance emitting member, a retaining member, and an inverted fragrance bottle.

A heater arrangement for a volatile material dispenser includes a cylinder defining an opening and a resistor embedded in the cylinder. The dispenser further includes a housing configured to receive a refill containing a volatile material and a wick. The housing includes a first cavity configured to support the heater arrangement. Further, the dispenser is configured such that, when the refill is received within the housing, the opening receives the wick therein so that a radial gap is formed between the heater arrangement and the wick.

It is an Evaporative Humidifier Air Purification combo unit performing the functions of both cool mist evaporative air humidifier as well as the air purifier. The optional attachments make it easy for the consumers to make use of any of the functions it is capable of performing. It even solves the problem of degradation of performance and material life prevalent in conventional standalone air purifier units. The evaporative humidifier is motor driven and is provided with proprietary HEPA quality nano membrane with high chemical stability, waterproof, water vapor permeability, windproof, breathable, acid and alkali resistant, anti-corrosion and anti-bacteria functions etc. membrane used in combination with humidifier cooler pads. On using the water tank, the setup performs the function of air humidifier using the air sucked from the wick using the fan and aiding the evaporation of water in the tank. While on replacing the water tank with the air cover, the same fan sucks air through wick and blows the purified air upwards in consonance to the mode i.e. High, Medium or Low.

An ergonomic scent diffuser having a first housing with electrical components connected to a second housing having a heating element disposed within. Slidably connected to the second housing is a cap. The cap has depressions adjacent an outer end to provide an ergonomic grip. The cap also has guide rails and retaining members that retain and position a fragrance emitting member over the heating element.

An air scenting assembly includes: a scent container which at least initially contains a scent perfume, and a scent perfume extracting mechanism, which is configured to release scent perfume from the scent container. The scent perfume extracting mechanism includes a scent perfume absorbing element insertable into said scent container, a scent carrying material, a dripping mechanism arranged onto said scent perfume absorbing element, said dripping mechanism is configured to deposit scent perfume from the scent container onto said scent carrying material, and a limiter to restrain extraction of scent perfume from the scent container, wherein the limiter comprises an air duct between the scent perfume absorbing element and the dripping mechanism, and the limiter is air flow controlled, wherein one end of said air duct is placed inside said scent container, and wherein the other end of said air duct is connected to a nozzle, said nozzle being arranged on said scent carrying material so that when said scent carrying material is drenched to saturation, no more air can pass through said scent carrying material and up into said nozzle and said air duct, and so that when the scent carrying material is dry enough passage of air through said air duct is allowed.
