A blower has: a fan generating an air flow in an axial direction of a rotary shaft; a tubular motor holder 30 formed in a tubular shape and holding the motor radially inside thereof; and a fan case part accommodating the motor, the motor holder, and the fan and forming an air flow path. A first rectification parts that is integrally formed is provided on an inside portion of the fan case part. The first rectification part is formed in a rib shape by a first to fourth blade, weakens a rotational component of a flow of air discharged from the fan, and guides the air to smoothly flow in the axial direction. The motor holder is configured so as to have an axial length smaller than the motor.

A blower in one aspect of the present disclosure includes: a housing including a first discharge port; a motor in the housing; a fan in the housing; an attachment fitting portion; and a motor drive circuit. The attachment fitting portion is configured to detachably attach, to the first discharge port, an attachment including a second discharge port. The motor drive circuit (i) delivers a designated power to the motor and (ii) performs a constant power control that maintains a magnitude of an electric power delivered to the motor at a magnitude of the designated power.

A power source for inflation systems. Specific embodiments relate to inflation systems that use an electrically-powered inflation system, wherein the power source of the inflation system is a solid state battery. Particular embodiments may find use in connection with inflating evacuation slides or life rafts on board a passenger transportation vehicle, such as an aircraft or marine vessel. Other embodiments may be used for inflating shelters, life vests, or any other inflatable safety device that requires a rapid inflation.

A neck fan includes an arc-shaped shell configured to hang around user's neck and at least four fan assemblies arranged in the shell. The shell includes a first part and a second part. Each of the first part and the second part defines an accommodating space, air inlets and air outlets communicated with the accommodating space, at least one partition is arranged in the accommodating space and configured to divide the accommodating space into at least two accommodating parts arranged along an extension direction of the shell. Each of the fan assemblies is arranged in one of the at least two accommodating parts and is configured to direct air into the one of the at least two accommodating parts through corresponding air inlets and to direct air out of the one of the at least two accommodating parts through corresponding air outlets.

A portable blower assembly includes a cylinder that has an exhaust port integrated into the cylinder. A handle extends around the cylinder and the handle can be gripped by a user for directing the exhaust port toward a vehicle. A blower is rotatably integrated into the cylinder to urge air outwardly through the exhaust port thereby facilitating the air to be directed onto the vehicle for drying the vehicle when the blower is turned on. A heater is integrated into the cylinder such that the heater is in thermal communication with an interior of the cylinder. The heater is positioned between the blower and the exhaust port to heat the air is blown by the blower for enhancing drying the vehicle.

The application provides a misting fan, including: a fan assembly, including a fan blade and a motor configured to drive the fan blade to rotate; a nozzle, provided on the fan assembly and configured to spray water mist; a rack configured to support the fan assembly; the rack includes an extending portion configured to be placed and extending in a plane; and the misting fan is provided with a moving wheel configured to walk, and the moving wheel is provided in the extending portion.

An outlet tube includes a first rib, a second rib, and a channel positioned between the first rib and the second rib. The first rib extends from a surface of the tube. The first rib tapers between a first thickness and a second thickness. The second rib extends from the surface of the tube. The second rib tapers between the first thickness and the second thickness. The channel has a first width between adjacent first thicknesses and a second width between adjacent second thicknesses. The first width is greater than the second width.

The present disclosure provides an inflation product with a built-in air pump, including an air pump (1), a connection piece (2) and an inflation product (15). The inflation product (15) includes a through hole (151) penetrating from inside to outside, the connection piece (2) is fixed at an opening of the through hole (151), the air pump (1) and the connection piece (2) are detachably connected, and the through hole (151) is provided for the air pump (1) to protrude into with a front end of the air pump (1) exposed outside the through hole (151). 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).
