A ceiling fan mount assembly having a downrod assembly with a downrod and a motor assembly comprising motor and including a motor shaft. The ceiling fan mount assembly further includes a downrod plate coupled to the downrod and a shaft coupler coupled to the motor shaft and coupled to the downrod plate, whereby coupling the downrod plate to the shaft coupler suspends the motor from the downrod.

A blower including a volute, a motor, a blower wheel, and a box. The motor is disposed on the volute. The motor includes a spindle, a rotor assembly, a stator assembly, a motor housing, a front-end cover, a rear-end cover and a capacitor. The rotor assembly is disposed on the spindle. The stator assembly and the motor housing are integrated and sleeved on the rotor assembly. The front-end cover and the rear-end cover are installed on the two ends of the motor housing, respectively. Two ends of the spindle are supported on the bearing of the front-end cover and the bearing of the rear-end cover, respectively. The front end of the spindle extends into the volute and is connected to the blower wheel. The capacitor is disposed in a cavity formed by the box and the rear-end cover.

An assembly including a wearable blower having a fan, a motor, an air duct having a duct housing thereof, a handle attached to the duct housing, and a hanger disposed on the duct housing. The hanger has an attachment part attached to the duct housing and adjacent to the handle and a hanger part connected to the attachment part for holding an accessory attached to the blower. The hanger part rotates with respect to the duct housing at a first hanging position whereat the hanger part is unfolded with an opening mouth for holding the accessory of the blower and the hanger part rotates with respect to the duct housing at a second folded position. Thus, the arrangement of the hanger can help the user to hold the accessory of the blower at the work states.

Various embodiments are provided herein for a system and method for air compression. In at least some embodiments provided herein, there is provided a compressor device having an annular chamber, at least one inlet port, at least one blade, at least one dynamic partition wall and at least one outlet, wherein when the at least one partition wall is in a closed position, the at least one blade approaching the at least one partition wall causes the air to compress and wherein when the at least one partition wall is in the open position, at least one blade moves from a first side to a second side of the at least one partition wall. The compressor device may contain a gearbox train configured to move the at least one partition wall from the closed position to the open position when the at least one blade is within a predetermined distance.

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 apparatus includes a pipeline-transport compressor configured to receive, in use, a product stream from a pipeline. The cooler unit is configured to receive, in use, a cooler air intake from the pipeline-transport compressor. This is done in such a way that removal of the cooler air intake by the cooler unit, in use, moves the cool air across the cooler bundles and out through the cooler unit, and cools the pipeline-transport compressor. An air exhaust power generation unit is configured to generate, in use, electric power in response to the cooler unit, in use, urging, at least in part, the cooler air intake toward, at least in part, the air exhaust power generation unit.

A motor assembly having a rotational axis includes a motor housing comprising a plurality of cooling openings extending therethrough and defining a chamber. The motor assembly also includes a stator fixedly coupled to the motor housing and positioned within the chamber. A rotor is coupled to at least one of the motor housing and the stator, wherein the rotor is configured to rotate about the axis and is positioned within the chamber. The motor assembly includes a fan having a first inlet side on a first axial side of the fan and a second inlet side on a second, opposing, axial side of the fan. The fan is configured to draw cooling air in a first direction through the at least one cooling opening into the first inlet side, and the fan is also configured to draw cooling air in a second, opposite direction into the second inlet side.
