A portable air purifier may include an inlet configured to form a path along which air is suctioned, a filter disposed at an upper side of the inlet and configured to purify air which enters through the inlet and moves upward, a sanitizing portion disposed at a lower side of the filter, installed at a height allowing the sanitizing portion to overlap the inlet, and configured to irradiate sanitizing light toward the filter, and a fan module disposed at an upper side of the filter and configured to rotate a fan to blow air in a direction toward the upper side of the filter.

An air cleaner may include a case having a discharge port formed at an upper side and vertically open; a blower fan disposed inside of the case, and blowing air inside the case toward the discharge port; a discharge body disposed on an upper side of the case in which the discharge port is formed, and having a discharge passage that guides the air, blown by the blower fan, toward the discharge port; a discharge guider rotatably disposed on an upper side of the discharge body, and having a plurality of grills bent so as to guide air, flowing upward through the discharge passage, in a radially outward direction; and a motor that rotates the discharge guider disposed on the discharge body.

The present disclosure relates to an air cleaner. The air cleaner according to an embodiment of the present disclosure includes: a case having a discharge port which is formed on an upper side thereof and is vertically open; a blower fan disposed inside the case, and causing air inside the case to flow to the discharge port; a discharge guider disposed on the upper side of the case where the discharge port is formed, rotating about a rotation axis formed in an up-down direction, and changing a wind direction of air discharged through the discharge port; and a motor rotating the discharge guider, wherein the discharge guider includes a plurality of grills which are bent in a first direction perpendicular to the up-down direction, and are spaced apart from each other in the first direction.

An air cleaner includes a blower, a circulator disposed over the blower, and a mover coupled to the circulator and configured to change an arrangement of the circulator. The circulator includes a lower cover, an upper cover disposed over the lower cover, a blower fan rotatably disposed between the lower cover and the upper cover, a motor disposed on an upper side of the lower cover and rotating the blower fan, an inner cover disposed over the lower cover and receiving a lower portion of the blower fan, and a bell mouth protruding upwardly from an inner circumferential end of an inner plate of the inner cover and spaced apart outwardly from a circumferential surface of a suction guider of the blower fan, so as to guide air, drawn in through an inlet of the lower cover, toward an inlet of the blower fan.

An air cleaner includes: a blower having an outlet formed on an upper side thereof; a circulator disposed over the blower and configured to control a wind direction of air flowing upwardly through the outlet; and a mover coupled to the circulator and configured to change an arrangement of the circulator, wherein the circulator includes: a lower cover having a lower plate coupled to the mover, and having an inlet formed around the lower plate; an upper cover disposed over the lower cover and having an outlet; a blower fan rotatably disposed between the lower cover and the upper cover, and having a circular inlet formed on a lower side and an annular outlet formed on an upper side; and a motor disposed on an upper side of the lower plate, and rotating the blower fan.

An air circulator includes a housing having a first inlet and a first outlet, an oblique-flow fan disposed in the housing, and a motor rotating the oblique-flow fan. An outer wall of the housing includes a first outer wall extending in a front-rear direction and a second outer wall having the first inlet and extending from an edge of the first inlet towards the first outer wall to be enlarged in a radially outward direction. An outer surface of the second outer wall comprises a first surface that extends towards the first outer wall to be rounded outwards, and forms a surface continuous with an outer surface of the first outer wall, thus guiding air flowing along an outside of the first inlet so that the air flows forwards along the outer surface of the first outer wall.

An air outlet device includes an air duct case and an air guide assembly. The air duct case including an air outlet member. The air outlet member includes an air cavity formed inside the air outlet member, an air inlet at one side of the air outlet member and communicating with the air cavity, and an air outlet at another side of the air outlet member and communicating with the air cavity. The air guide assembly includes an air outlet hole. The air guide assembly is movably mounted at the air outlet member and located at the air outlet. The air guide assembly is provided close to a surface of the air outlet member and is movable along the surface of the air outlet member to change an angle of an airflow from the air outlet.

Disclosed is a stowable airflow diverter for removable attachment to a floor vent of a turbine aircraft. The air diverter comprises vertical ducting extending from a base. A flexible gasket and magnets are attached to the base for engagement with the floor vent. A nozzle attached to the vertical ducting redirects the airflow emanating from the floor vent from horizontal to vertical in order to direct air conditioned air into the cock pit of the aircraft. In an alternate embodiment, the nozzle is rotatable with respect to the vertical axis of the duct. In another alternate embodiment, the nozzle and vertical duct comprise telescoping segments such that the device can be collapsed into the floor vent.
