Provided is a rotator structure of a nanomist-generating device which generates a nanomist by rotating a rotator having a conical shape, wherein a lower portion of the rotator is immersed in water and mist-scattering ports are disposed in an upper portion; the device generates a nanomist by scattering the water through the ports, the water being drawn up along an inner wall surface of the rotator by rotating the rotator; and a radius at an upper end of the ports is an upper portion radius R1, a height to the upper end of the ports from a waterline L is a drawing height H, and a mean angle between a horizontal line and the inner wall surface is a side surface mean angle 1; and the angle 1 is set within 5% of for satisfying a basic structure equation R1 sin.sup.3 +2 H cos sin.sup.2 +H cos.sup.3 =0.

A gas humidifier can have a gas channel comprising an inlet and an outlet. A portion of the gas channel can have a region having a reduction in cross-sectional area relative to the portions of the gas channel outside of the region. A water conduit can extend from the region to a water reservoir. A heating element can heat water entering the region from the water conduit. Water vaporized using the heating element can join the flow of gases passing through the gas channel in use.

Provided is a floating type humidifier, and particularly, a floating type humidifier which can prevent, when a floating type humidifier discharging water particles or vapor while floating on water in a water tank loses a balance thereof and falls, the water stored in the water tank from flushing abruptly and even though a water tank falls due to external force such as an earthquake or carelessness of a user, water stored in the water tank is prevented from being abruptly discharged to minimize a cleaning operation which occurs as much water is discharged, the floating type humidifier can prevent foreign materials from being input in the water stored in the water tank, and the floating type humidifier can be stably used even at places including a hospital, a kindergarten, and a home where a lot of children move.

A CPAP device for delivering pressurized, humidified breathable gas for a patient includes a flow generator configured to pressurize a flow of breathable gas. The flow generator includes an air outlet and a removable water container configured to humidify the pressurized breathable gas received from the flow generator. The water container includes an air inlet and an air outlet. The CPAP device further includes a first elastomeric face seal configured to sealingly abut against a substantially flat portion of the water container surrounding the water container air inlet, the first elastomeric face seal being located at an intermediate position between the flow generator air outlet and the water container air inlet when the water container is placed into position to pneumatically communicate with the flow generator. In addition, the CPAP device includes a second elastomeric face seal, a portion of which is configured to sealingly abut against a substantially flat external surface portion of the water container surrounding the water container air outlet.

A floating-type humidifier according to an exemplary embodiment of the present invention includes: a floating body which floats in a reservoir that accommodates water; an ultrasonic wave generation unit which is installed by being inserted into the floating body, and atomizes the water, which is introduced into a lower side of the floating body, into a water particles state by means of ultrasonic vibration; a guide tube which is detachably coupled to the floating body, is installed above the ultrasonic wave generation unit, guides the water particles, and has a fan installation hole horizontally and penetratively formed in a lateral portion of the guide tube; a blower fan which is coupled in the fan installation hole, and injects air into the guide tube so as to discharge the water particles to an upper side of the guide tube; and a discharge groove which is formed in an upper surface of the floating body so as to communicate with the fan installation hole in which the blower fan is mounted.

The present invention relates to a moisture-generating device (10) for generating a moisture-enriched air flow or gas flow, said device comprising: a housing (H) having a main extension direction (HR) and an inflow region (2) and an outflow region (3), and having a lateral inlet region (EB) which extends at a specified angle to the main extension direction (HR), and having a mixing region (MB), a water injector (WI) which is located in the lateral inlet region (EB) and by means of which atomized water can be introduced into the mixing region (MB) at the specified angle with or counter to the main extension direction (HR); a separator grid (SG) which is located in the mixing region (MB); and a homogenizing region (HB), which adjoins the mixing region (MB) in the main extension direction (HR), and wherein a degree of moisture of at least regions of the gas or air flow in the homogenizing region (HB) can be homogenized.

A gas humidifier can have a gas channel comprising an inlet and an outlet. A portion of the gas channel can have a region having a reduction in cross-sectional area relative to the portions of the gas channel outside of the region. A water conduit can extend from the region to a water reservoir. A heating element can heat water entering the region from the water conduit. Water vaporized using the heating element can join the flow of gases passing through the gas channel in use.

A humidifier includes a container defining a container cavity; a cover positioned over a container opening of the container cavity, the cover defining a body opening and a vent opening, the body opening and the vent opening in fluid communication with the container cavity; an attachment mechanism configured to attach the humidifier to a vent; and a wicking pad mounted in the container cavity between the vent opening and the body opening.

Disclosed herein is a portable air purifier. The portable air purifier includes: a body; first to third accommodation portions configured to have respective open top surfaces in order to separately accommodate a battery, an air compressor, and water; first to third covers configured to selectively open and close the respective open top surfaces of the first to third accommodation portions; an air inlet connected to the lower portion of the second accommodation portion, and configured to accommodate a pre-filter; a siphon pipe positioned upright inside the water of the third accommodation portion, and configured such that the top thereof is connected to the air outlet of the air compressor; a cannula installed on the top of the third accommodation portion, and configured to supply purified, humidified air to a user; and a power switch configured to control the amount of air to be supplied.
