The present invention relates to a fan wheel structure comprising a cover body connected with a plurality of fan blades, a hub, and a plurality of fan blades. The cover body is disposed on a hub. The hub has a top surface and a receiving space defined on the top surface. Each of the fan blades has a joining end protruding into the receiving space. The cover body has a clamping side combined with the top surface of the hub and a plurality of joining grooves spaced around the cover body and individually combined with the corresponding joining ends of the fan blades to fix the fan blades.

The present invention relates to an improved structure of fan blades, which comprises a hub, a connecting part, and a plurality of fan blades. The connecting part has a coupling section and a plurality of slits. The connecting part is sleeved around the perimeter of the hub through the coupling section. The slits are circularly disposed close to the perimeter of the connecting part. The fan blades individually have a first end and a second end; the first ends are individually embedded in the slits and combined with the connecting part. Be means of the present invention, the disadvantage of the combination through a non-integrated structure of the fan blades and the hub in the prior art can be overcome.

A compressor device includes a housing with a cavity. The compressor device includes a rotating group supported for rotation within the housing. The rotating group includes a shaft that supports a compressor wheel proximate a first end of the shaft. A second end of the shaft extends away from the compressor wheel through the cavity of the housing. The compressor device further includes a moisture evacuation system configured to remove airborne moisture from the compressor device. The moisture evacuation system includes a shaft passage extending through the second end of the shaft and a housing passage extending through an outer wall of the housing. The shaft passage is fluidly connected to the cavity. The housing passage is fluidly connected to the shaft passage. The moisture evacuation system is configured to direct the airborne moisture from the cavity, through the shaft passage, and out of the housing via the housing passage.

A portable blowing device configured for being worn around a neck of a human body, includes two arms each defining an airflow channel therein; and fans received in the arms respectively. The arm includes an inner side wall close to the neck and an outer side wall connected to the inner side wall. The arm includes an air inlet and an air outlet in communication with the airflow channel respectively. The air inlet is arranged at the inner side wall and/or the outer side wall. The fan is configured to generate an airflow passing through the air inlet, the airflow channel and the air outlet in sequence.

A blower, including: a motor; a tubular wind wheel, a mounting plate and a connection part. The tubular wind wheel includes a plurality of blades and a plurality of connection rings. The plurality of blades is connected to each other to form an elongated hollow body. The connection part is disposed in the elongated hollow body. The mounting plate is disposed outside one end of the tubular wind wheel. The motor is disposed on the mounting plate. At least a part of the motor extends into the elongated hollow body to connect to the connection part.

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.

The present disclosure relates to a flow generator.

A flow generator according to an embodiment of the present disclosure may include: a suction portion into which air is suctioned; a fan introducing the air introduced into the suction portion in an axial direction to discharge the air in a radial direction; a fan housing in which the fan is installed and which guides the air discharged from the fan; and a cover surrounding the fan and the fan housing. The fan housing may include: a housing plate supporting the fan; a guide wall protruding from one surface of the housing plate to surround at least a portion of an outer circumference of the fan; a first fan passage provided between at least a portion of the outer circumference of the fan and the guide wall; a second fan passage which is provided between the outer circumference of the fan and the cover and through which the air passing through the first fan passage flows; and a discharge portion located outside an outer surface of the guide wall to discharge the air passing through the second fan passage.

A compressor for a turbocharger includes an inlet-adjustment mechanism in an air inlet for the compressor, operable to move between an open position and a closed position in the air inlet. The compressor housing upstream of the inlet-adjustment mechanism defines a series of acoustic cavities, and openings are defined in the compressor housing wall leading into the acoustic cavities. The openings and cavities are aimed at mitigating noise and flow pulsation in the air inlet caused when the inlet-adjustment mechanism is adjusted to the closed position to effectively reduce the inlet diameter approaching the compressor wheel.

A blower device has a fixing position which is easily changed and the increase in cost is greatly suppressed. A blower device in which a flange having a fixing attaching foot is attached to rails formed on an outer circumferential surface of a casing, and a retaining block is attached to the flange to secure the flange to the casing, the retaining block includes a first block, a second block, and a connecting portion having smaller width and connecting the first block and the second block, the first block and the second block each include a retaining leg portion and a latching leg portion, and a projecting portion is formed on a side surface of the retaining leg portion and ribs are formed at both sides of the projecting portion.

A blower may include a first case and a second case provided above the first case and having a first tower and a second tower that have a passage therebetween. A display assembly is received in the second case at a position that does not interfere with air flowing in the passage. An inner surface of the second tower and an outer surface of a diffuser define a space in which the display assembly is received.
