A cover used in a ventilation fan includes a noise reduction structure and a shelter. The noise reduction structure has an air inlet, a flat portion surrounding the air inlet, and a peripheral portion surrounding the flat portion. The sidewall of the flat portion extends in a vertical direction from the peripheral portion. The bottom surface of the flat portion extends in a horizontal direction from the sidewall, and is a flat surface. The shelter is disposed on the peripheral portion and covers the air inlet.

Cover, fan unit, and ventilation fan

A ventilation fan device includes a base, a fan module, and an air guide assembly. The base includes a cover and a shell. The cover includes a first inlet and a first outlet. The shell includes a second outlet. The cover is combined with the shell. The fan module is installed on the shell and includes a housing and a centrifugal fan. The housing includes a second inlet and an air duct communicating with the second inlet. The housing includes a wing-shaped part located in the air duct. The centrifugal fan is disposed in the housing. The air guide assembly includes a stepper motor and an air guide plate. The stepper motor is installed in the wing-shaped part. The air guide plate is disposed in the housing and is driven by the motor.

Ventilation fan device

A semiconductor package may include a package substrate including a dummy via on a first side of the package substrate, an interposer module on a second side of the package substrate opposite the first side of the package substrate, and a stiffener ring on the second side of the package substrate and including an edge that is substantially aligned with the dummy via.

Semiconductor package including package substrate with dummy via and method of forming the same

An air mover is provided. The air mover includes a housing, a spacer, a co-axial motor, a first fan and a second fan. The housing includes a first housing member and a second housing member. A first inlet, a second inlet and an outlet are formed on the housing. The first inlet is formed on the first housing member and the second inlet is formed on the second housing member. The spacer is disposed between the first housing member and the second housing member. The co-axial motor includes a shaft, wherein the co-axial motor is disposed on the spacer. The shaft includes a first free end and a second free end. The first free end extends in a first direction, and the second free end extends in a second direction.

Air mover

The present disclosure provides a fixing structure including a base, a first fastener, and a second fastener. The first fastener is disposed on the base and comprises a first hook portion, a first accommodation portion and a first opening portion. The second fastener is disposed on the base and comprises a second hook portion, a second accommodation portion and a second opening portion. A guiding groove is defined by and located between the first and second fasteners and is in communication with the first and second accommodation portions. A positioning channel is defined by the guiding groove, and the first and second accommodation portions, collaboratively. The first and second opening portions are located on the opposite sides of the positioning channel, respectively.

Fixing structure and ventilation fan therefor

A ventilation fan according to the invention comprises a fan module, a fire damper module and a cover module. The fire damper module comprises a link frame, a fire damper body and an adjustment element. The fire damper body is disposed in the link frame and detachably linked up with the link frame. The adjustment element is disposed on the fire damper body and near an opening of a flange of the fire damper body. The adjustment element comprises a fixed portion, a stop portion and a trace portion. Wherein the stop portion abuts and shields the opening when no electrical wire passing through the opening. Wherein when the cover module comprises an electronic device having an electrical wire, the trace portion abuts the opening and the electrical wire passing through the trace portion and the opening to connect to the fan module.

Ventilation fan

A ventilating fan includes a driving device, a rotating blade assembly, and a frame structure. The driving device drives the rotating blade assembly to rotate. The rotating blade assembly includes a hub and at least one blade group arranged on the periphery of the hub. The driving device and the rotating blade assembly are disposed in the frame structure. The frame structure includes a main body and a first mounting plate. The main body is formed by a plurality of side portions, and each side portion has at least one bending part for connecting to the adjacent side portion. At least one of the side portions has a first slot, which is disposed adjacent to the corresponding bend part. The first mounting plate is disposed corresponding to the first slot and located in the main body, and the first mounting plate has at least one fixing portion.
