Abstract: A structure for fixing a cable for a waterproof fan case according to the present disclosure includes: a frame on which a motor is installed, and a blade is rotatably installed in a state in which a driving shaft of the motor is connected to a front side thereof; an insertion tube which extends rearward from the frame, has therein an insertion hole to which a power line connected to the motor is penetratively coupled in a front and rear direction, and has a gap portion formed to be split at one side in a transverse direction; and a coupling ring which has a hollow portion that is penetratively formed in the front and rear direction so that the coupling ring is correspondingly coupled to an outer circumference of the insertion tube in a male-female manner, and has a pressing protrusion that is formed to protrude on an inner circumferential surface of the coupling ring so as to press and support an outer circumference of the power line through the gap portion when coupling the coupling ring to the insertion tub

Abstract: A floating type humidifier with an increased humidification amount according to an exemplary embodiment of the present invention includes: a floating body which floats on water accommodated in a water tub and has a hollow portion vertically and penetratively formed at a central portion of the floating body; an ultrasonic generator which is installed in the hollow portion and configured to atomize water, which is introduced at a lower portion, to create humidification particles by using ultrasonic vibration; a humidification particle guide unit which is installed on an upper portion of the floating body and guides the humidification particles so that the humidification particles move upward along a guide hole in the humidification particle guide unit; and an air pressurizing portion which is provided in the humidification particle guide unit and pressurizes air so that the humidification particles are moved upward by the pressurized air.

Abstract: A water splash prevention cap for a floating type humidifier according to an exemplary embodiment of the present invention includes: a body which has therein a vacant space and is coupled to a discharge port of the floating type humidifier; at least one inlet portion which is formed to be opened at a lower circumference of the body to draw humidification particles created by the floating type humidifier; an outlet portion which is formed at an upper side of the body and discharges the drawn humidification particles; and a collision inducing portion which extends from a lower portion of the body in the space portion and induces a collision of some of the humidification particles.

Abstract: Provided is an apparatus for reducing noise of a floating-type humidifier by using a cap. The apparatus for reducing the noise of the floating-type humidifier by using the cap includes a water tank lid coupled to an upper portion of a water tank in which the floating-type humidifier is floated and having an opening, through which a portion of the floating-type humidifier is exposed, in an upper portion thereof and a cap having a predetermined height along a circumference of the opening to reduce an amount of air introduced into the floating-type humidifier. The cap is provided with a through-part, through which a portion of the exposed floating-type humidifier passes, in an upper portion thereof.
