Abstract: Provided is a diffuser equipped with an integrated cover that is opened and closed by an air current formed when a fan module is driven to control the spread of scent. The diffuser includes a body forming an exterior, a base inserted and fixed into the body and having a through-portion formed on one surface thereof, and an aroma container coupled to the base, wherein the base includes a cover rotatably provided on the through-portion, and an internal space of the body and an internal space of the base are selectively communicated with each other as the cover is rotated.

Abstract: The present disclosure relates to an insulated electric wire, and more particularly, to an insulated electric wire that has characteristics of a low dielectric constant and a high partial discharge inception voltage (PDIV) by forming a plurality of micropores inside insulating material of an insulating layer. According to the present disclosure, the insulated electric wire may have the plurality of micropores evenly dispersed inside the insulating material of the insulating layer to have the low dielectric constant without lowering the thermal and mechanical properties and increase the PDIV, so the insulated electric wire can be used as the insulated electric wire for the next-generation electric vehicle motors that use a higher voltage than the existing voltage.

Abstract: A method and server for generating a question for personality and aptitude tests using a question and answer network based on a language model are disclosed. The server according to the present disclosure includes a communication unit configured to communicate with a terminal, a database configured to store tester information, a memory configured to store artificial intelligence model data for a generative artificial intelligence model, and a processor configured to generate personality and aptitude question information suitable for characteristics of a person from personal behavior characteristic information and existing question information by using the generative artificial intelligence model.

Abstract: The present invention relates to an air cleaner, including a body forming an exterior; a suction portion formed on the body to suck air; a discharge portion formed on the body and discharging the air sucked through the suction portion; and a fan module provided in the body to form a flow of air flowing from the suction portion to the discharge portion, wherein the fan module includes: a driving portion forming a rotation shaft and generating power; a fan receiving the power from the driving portion and rotating about the rotation shaft; and a shroud accommodating the fan and provided between the suction portion and the discharge portion to guide the air sucked through the suction portion to the discharge portion, and the shroud includes a guide portion guiding foreign substances introduced through the discharge portion in a direction opposite to the flow of air.

Abstract: Provided is a dual structure humidifier, and more particularly, a dual structure floating-type humidifier with a noise reduction function. The dual structure humidifier includes a water tank in which a fluid is contained, a floating body which floats in the fluid in the water tank and performs a humidification operation using an ultrasonic module provided therein, a blowing fan which introduces external air into the water tank and the floating body or discharges the air in the floating body to the outside, and a water tank case which is provided to form a predetermined separation distance from the water tank and surround an outer circumference of the water tank and has air intake ports formed at one side to communicate with the blowing fan and reduce noise generated inside the water tank.

Abstract: A waterproof fan according to an embodiment of the present invention includes: a blade module configured to be operated by a motor; and a frame having an accommodation hole that accommodates the blade module, the frame being formed to surround the accommodation hole, and the frame includes an opening that opens a part of the accommodation hole.

Abstract: According to an exemplary embodiment of the present invention, a floating-type humidifier includes a lower body which has a buoyancy space formed along an inner edge to float in water and has a water inlet formed so that water flows into a lower center; an upper body formed with a hollow tube communicable with the water inlet; and supporter formed in an elastically deformable closed curve, in which the supporter is in contact with an upper end of the lower body and a lower end of the upper body to couple the lower body and the upper body to each other.

Abstract: Various embodiments of the present invention disclosed herein relate to an air cleaner, and may suck outside air and purify and sterilize the outside air, and may perform sterilization of a filter. An embodiment of the invention disclosed herein discloses an air cleaner including a body forming an appearance; a suction unit formed on the body and introduced with outside air; a discharge unit formed on the body and discharging the air introduced through the suction unit; a fan module provided inside the body and forming a flow of air introduced into the suction unit and discharged to the discharge unit; a filter unit provided inside the body to filter the air introduced into the suction unit; and a light source unit provided inside the body and irradiating light toward an inner side surface of the filter unit.

Abstract: A floating ultrasonic humidifier capable of generating ultraviolet rays according to an embodiment of the present invention includes: a floating body configured to float in a water tub that accommodates water; an ultrasonic humidification generating module disposed in the floating body and configured to generate humidification particles by means of ultrasonic vibration; and an ultraviolet ray generating module provided in the floating body or the ultrasonic humidification generating module and configured to emit light within an ultraviolet region to a space in the water tub.
