The front end of the air pump (1) includes an air inlet (3) in which a normally-closed switch is mounted, and an air inlet sealing cover (5) for driving the normally-closed switch (4) to be pressed down is covered on the air inlet (3).

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.

A blower includes a motor, a fan driven by the motor to rotate about a first axis, a power supply device, and a housing assembly accommodating the motor and including an inner duct and an outer duct assembly. The inner duct is formed with an inner air inlet. The outer duct assembly surrounds the inner duct. The outer duct assembly includes an outer duct and a hood, where the outer duct is disposed on a front side of the hood, an outer air outlet is formed at an end of the outer duct facing away from the hood, an outer air inlet is formed on the hood and has a front end portion and a rear end portion along a direction of the first axis, and the inner air inlet is disposed between the front end portion and the rear end portion along the direction of the first axis.

A head-mountable flow generator is configured to deliver a flow of breathable gas at a continuously positive pressure with respect to ambient air pressure to a patient interface in communication with an entrance to a patient's airways including at least an entrance of the patient's nares, while the patient is sleeping, to ameliorate sleep disordered breathing. The flow generator includes a motor, an impeller assembly and housing that encases the motor and the impeller assembly. The housing is configured to be mounted on the patient's head and comprises an inlet to receive the flow of breathable gas and a pair of opposing outlets to deliver the flow of breathable gas. In addition, the impeller assembly is configured to pressurize the flow of breathable gas received from the inlet, and the housing is configured to convey the pressurized flow of breathable gas through both outlets.

An electric tool, a blower and a method of discharging electrostatic charge in an electric tool. The tool may include a housing, a motor supported by the housing and powered by a power source, the motor including a rotor, a fan supported by the housing and driven by the motor to cause an air flow, and a wire electrically connected between the rotor and a terminal of the power source and operable to dissipate electrostatic discharge in the tool.

A blower (100) includes a blower attachment housing (112), a power head housing (122) having a handle (130) operably coupled thereto, a motor (140) disposed in the power head housing (122), a fan (160) disposed in the blower attachment housing (112), a battery (150), and an intake chamber (174) disposed between the motor (140) and the fan (160) to enable the air to enter the blower (100) between the motor (140) and the fan (160).

The present invention is directed to an outdoor blower that is capable of safely releasing any electrostatic charge that builds up in the blower. During the operation of the blower, electric charge builds up in the housing and components of the blower as particles in the air are moved through the blower. The blower includes a wire contact in the handle that is electrically connected to various other components in the blower. As electric charge is built up in the blower, it can be passed to the wire contact, which is graspable by a user, who acts as a ground and is able to release any charge that builds up.

Provided is an axial flow blower capable of improving an intake efficiency even when air is introduced from a plurality of suction openings. An axial flow blower includes a housing including an air blowing passage extending from a plurality of suction openings (lateral suction opening and lower suction opening) to an ejection opening, an electric motor, and an air blowing fan that blows air from the plurality of suction openings (lateral suction opening and lower suction opening) toward the ejection opening. An air blowing guide member is provided closer to the plurality of suction openings (lateral suction opening and lower suction opening) than to the air blowing fan, inside of the plurality of suction openings (lateral suction opening and lower suction opening). The air blowing guide member guides air introduced into the air blowing passage from the plurality of suction openings (lateral suction opening and lower suction opening) toward the air blowing fan.
