The present disclosure relates to a portable air purifier and the fan module provided therin. In the disclosed invention, the portable air purifier includes a fan module that is disposed between a discharge surface and a filter, and suctions air having passed through the filter, in an axial direction, and discharges the air in a direction between the axial direction and a radial direction.

The disclosure relates to an asymmetrical double-outlet blower, including an upper case, a lower case and an impeller. The upper case includes an inlet. The lower case and the upper case are assembled to form a housing having an accommodation space, and form a first outlet and a second outlet. The accommodation space is in fluid communication with the first outlet, the second outlet and the inlet. The first outlet and the second outlet are disposed on a lateral periphery of the housing and face two opposite directions, respectively. An opening cross-sectional area of the first outlet is less than an opening cross-sectional area of the second outlet. The impeller is accommodated within the accommodation space of the housing, spatially corresponding to the inlet, and rotated around a rotation axis. An airflow is inhaled through the inlet and transported to the first outlet and the second outlet, respectively.

An assembly includes a first bracket and a second bracket. The first bracket includes a first member that includes a plurality of fingers and a first channel between the plurality of fingers. The first channel includes a plurality of teeth. A first flange extends from the first member and includes a first engagement surface. The second bracket includes a second member and a third member spaced from the second member. A second channel is formed between the second member and the third member. A second flange extends from the second member on an opposite side of the second member from the third member. The second flange includes a second engagement surface. In an installed configuration, the first bracket is secured to the second bracket; the first engagement surface faces the second engagement surface; and the plurality of fingers are inserted into the second channel.

Embodiments disclosed herein may provide an air conditioner having a case and a cover coupled to the case. A cover separation unit may separate the cover from the case at upper and lower sides. The cover separation unit may include a lever that slides along an outer surface of the case and a pusher rotatably coupled to the lever to rotate to push the cover. A guide may guide the pusher to rotate as the pusher is moved along an outer surface of the case.

An assembly includes a first bracket and a second bracket. The first bracket includes a first member that includes a plurality of fingers and a first channel between the plurality of fingers. The first channel includes a plurality of teeth. A first flange extends from the first member and includes a first engagement surface. The second bracket includes a second member and a third member spaced from the second member. A second channel is formed between the second member and the third member. A second flange extends from the second member on an opposite side of the second member from the third member. The second flange includes a second engagement surface. In an installed configuration, the first bracket is secured to the second bracket; the first engagement surface faces the second engagement surface; and the plurality of fingers are inserted into the second channel.

A fan frame structure includes a base portion and a wall portion. The base portion has at least one extension section vertically extended from an outer peripheral edge of the base portion, and the extension section has connecting sides. The wall portion is formed along the outer peripheral edge of the base portion through an insert molding process. The wall portion includes a plurality of wall segments connected to the connecting sides of the extension sections, and a clearance is formed between any two adjacent wall segments. With these arrangements, the base portion can better resist a wrapping force from the insert-molded wall portion to avoid deformation.

The invention relates to a fastening apparatus (1) for fastening a ventilator (2) to a carrier structure, having—at least two support elements (3a, 3b), each being connectable at the first end (4) thereof to the carrier structure, wherein at least two of the support elements (3a, 3b) have a fastening means (5) for fastening a ventilator (2), wherein—the support elements (3a, 3b) are connected at the second end (7) thereof to the adjacent support element (3a, 3b), such that the support elements (3a, 3b) mutually support each other, wherein—the fastening means (5) is spaced apart from a connection point (17), at which the second end (7) is connected to the adjacent support element (3a, 3b).

A blower unit can include an outer housing, an inlet subassembly, a fan subassembly, an outlet subassembly, and a grommet. The outer housing can have an aperture extend along a first axis between first and second ends. The inlet subassembly can be received in the first end of the aperture. The fan subassembly can be received in the aperture adjacent to the inlet subassembly and include at least one wire. The outlet subassembly can be received in the second end. The grommet can be positioned between at least part of the second end and the outlet subassembly. The at least one wire can extend through the grommet. The grommet can seal against the at least one wire. The grommet can seal between the outer housing and the outlet subassembly.

A neck-hanging fan, comprises a housing that can be worn on the neck and a fan assembly, wherein the two extended tail ends of the housing are provided with an accommodating chamber, and an air duct communicating with the accommodating chamber is formed in the housing, a fan assembly is arranged in the accommodating chamber, an air inlet hole communicating with the accommodating chamber is arranged on the housing, and a plurality of air outlet holes communicating with the air duct are arranged on the outer wall of the housing, and the plurality of air outlet holes are distributed along the extension direction of the air duct. The end of the air outlet away from the fan assembly is provided with a wind gathering plate extending into the air duct, wherein a plurality of wind gathering plates are provided.

An apparatus has a bed with bedding; an air mover; and an air outlet defined by the air mover to direct air into a sleep zone of the bed. A method includes operating an air mover to direct air into a sleep zone defined between a bed and bedding.
