Abstract: A blower of a hand dryer includes an air flow generation module and a blower housing. The air flow generation module includes an air case, an electric motor and a control circuit board The air case includes an air inlet and an air outlet gap. The blower housing is provided with the air flow generation module. The blower housing includes a first half shell and a second half shell. The second half shell includes a first sub-shell and a second sub-shell capable of being separated from the first sub-shell. The first sub-shell includes an opening. The opening is provided for installing the air flow generation module and exposing the control circuit board outside of the first sub-shell, the second sub-shell is mounted on the opening, and when the second sub-shell is separated from the first sub-shell, the control circuit board is being exposed.

Abstract: An air-guiding structure of a separable hand dryer, the separable hand dryer comprises an air outlet faucet and a working machine connected by the air-guiding structure. The air outlet faucet comprises at least one electrical wire and a ground wire. The air-guiding structure comprises an air pipe and an adapter pipe, and the shape of the air pipe is adjusted by an adjustment manner so that one end of the air pipe is fitted a position of the working machine and the air outlet faucet. The adapter pipe comprises a trunk, a manifold communicating with the trunk and allowing the electrical and ground wires to pass therethrough, and a seal provided in the manifold allows the electrical and ground wires to pass through but to restrict the passage of air. The trunk is connected to the air pipe, and the adapter pipe is adjusted by the adjustment manner.

Abstract: A hand dryer with reduced air-intake noise includes a housing, a flow-guide plate, and an air supply module. The housing includes an accommodating space and a plurality of narrow air inlets. The flow-guide plate is disposed inside the accommodating space, but the flow-guide plate is not contacted with the housing. The flow-guide plate includes a plurality of narrow air guide holes. The air supply module is disposed inside the accommodating space, and includes a blower that extracts air inside the accommodating space to generate a drying air flow after being started and an air-guide piece connected to the blower to receive the drying air flow. An interval between the narrow air inlet and the narrow air guide hole interferes with transmission of a sound wave formed by the air flowing between the narrow air inlet and the narrow air guide hole, so that generated noise can be greatly reduced.

Abstract: A watermark-free hand dryer includes a main body, an annular air discharge portion and a water absorbing portion. The main body generates high pressure airflow. The annular air discharge portion is connected to the main body and includes at least one extending section extended from the main body and a connecting section connected to the extending section. The extending section and connecting section surround to form an annular hand drying passage to receive user's hands. The annular air discharge portion further has at least one nozzle on an air discharge surface communicating with the annular air discharge portion. The nozzle forms an air discharge angle against the air discharge surface to output the high pressure airflow towards an air discharge side. The water absorbing portion is located on the main body and relative to the air discharge side to receive the high pressure airflow output from the nozzle.
