The present invention relates to a method for controlling a thermoregulated ventilation circuit (100) equipped with a control unit (40) and comprising an active humidifier (10). The active humidifier (10) further comprises, in turn, a cartridge (20) equipped with a humidification chamber (21) adapted to contain water to be heated for the humidification of the air through a heating element (30), and the thermoregulated circuit (100) further comprising at least one intake tube (120) for conveying the air exiting said cartridge and provided with heating means (123) for heating the air exiting said cartridge (20). The method according to the present invention is characterised in that said control unit (40) receives in input the patient's temperature data (Tp) detected by a patient's temperature probe (132) and regulates the operation of said heating element (30) of said cartridge (20) and the operation of said heating means (123) of the air exiting said cartridge (20) as a function of said patient's temperature (Tp).

The present disclosure provides a heating-type humidifier, including a water tank and a base. The water tank is arranged within the base, and the water tank includes a gas guide pipe, a gas outlet, and a water filling port; the gas outlet is communicated with the gas guide pipe. The base defines a cold gas tank and a heating tank that are communicated with the gas guide pipe, and the cold gas tank is communicated with the water tank through a water supply switch. The cold gas tank is communicated with the heating tank through a guide pipe, the guide pipe being a heat dissipation pipe.

A humidifier has a base and a housing. The housing has a steam exhaust vent and a vaporizer. The vaporizer includes a heating element surrounded by a removable porous sleeve that protrudes downwardly into water within a reservoir of the base. The sleeve wicks the water including its minerals and impurities into contact with the heating element wherein energization of the heating element causes the wicked water to convert to steam that rises through the exhaust vent and from the housing during a humidification mode.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source to a vaporization port where the vaporization port has lateral dimensions varying from 10 um to 300 um, applying heat to the liquid in the vaporization port with an at least one heating element located in thermal communication to the vaporization port, and releasing vaporized liquid from the vaporization port into the surrounding environment so that fluid is transported through the depth of the structure.

A vertical humidifier with a stepped evaporator includes a housing. An evaporative water trough is provided inside the housing, and the stepped evaporator is provided in the evaporative water trough. A fan is mounted under the stepped evaporator, and an air inlet end of the fan is communicated with an air inlet of the housing. A water tank is further mounted at the upper portion of the evaporative water trough, the stepped evaporator is mounted around the lower portion of the water tank, and the water tank is further communicated with the evaporative water trough through a water inlet. An air outlet is provided at the upper portion of the housing, and the air outlet is communicated with an air outlet end of the fan. The stepped evaporator is arranged in an airflow channel between the air outlet and the air outlet end of the fan.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source to a vaporization port where the vaporization port has lateral dimensions varying from 10 um to 300 um, applying heat to the liquid in the vaporization port with an at least one heating element located in thermal communication to the vaporization port, and releasing vaporized liquid from the vaporization port into the surrounding environment so that fluid is transported through the depth of the structure.

The fine water discharging element capable of transitioning between an adsorption state where water contained in a fluid to be treated is adsorbed and a discharge state where the adsorbed water is discharged to the fluid to be treated, the fine water discharging element comprising a base material portion, a plurality of particles and a nanochannel formed between the shell portions by laminating the plurality of particles on an outer surface of the base material portion in a rich viscoelasticity film shape. The fine water discharging element is transitioned between the adsorption state and the discharged state by changing the temperature of the water in the nanochannel by controlling an electrifying of at least one of the base material portion and the plurality of particles.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source through an inverse-opal wicking structure to a vaporization port where the vaporization port is formed by a through-hole in a structure connecting a first side of the structure to a second side, with all dimensions ranging from 10 um to 300 um, that is in fluid communication with the liquid source and the surrounding environment so that fluid is transported through the vaporization port between the first and the second side. The methods and apparatus includes plurality of heating elements that may be individually and/or selectively addressable by at least three electrode leads.

A humidifying apparatus includes a water tank provided to hold water, a heating device configured to heat the water held in the water tank, a discharge chamber disposed above the water tank and including an outlet configured to discharge steam generated in the water tank due to the water being heated, a guide chamber between the water tank and the discharge chamber configured to guide the steam generated in the water tank into the discharge chamber, and a screen at a central portion of the guide chamber and spaced apart from an inner sidewall of the guide chamber to form a gap between the screen and the inner sidewall, so that the screen interferes with a flow of the steam guided by the guide chamber and allows the steam to flow through the gap to then be guided by the guide chamber into the discharge chamber.

Systems and methods to treat an environment. The system includes a plurality of scent control material sources configured to output a scent control material (e.g., an oxidant) into the environment to reduce pathogens, dispose of scent molecules and their sources, and otherwise treat the environment. The system can include a controller communicatively coupled to the plurality of scent control material sources and cause one or more subsets of the plurality of scent control material sources to individually or collectively output scent control material into the environment.
