BLOWER
The present disclosure relates to a blower. The blower according to an aspect of the present disclosure includes: a lower case in which a suction port is formed; a fan disposed inside the lower case and blowing air introduced through the suction port upward; a first tower elongated to an upper side from the lower case and formed with a first discharge port opening forward; a second tower spaced apart from the first tower in a horizontal direction, elongated to an upper side from the lower case, and formed with a second discharge port opening forward; an air guide disposed inside the first tower and spaced apart from a front end of the first tower and elongated along a front and rear direction toward the first discharge port; and a handle disposed between the fan and the air guide and elongated from upstream of the air guide toward the front end of the first tower. The handle is disposed between the fan and the air guide, so that the blowing performance of the blower can be enhanced.
TECHNIQUE FOR SUPPRESSING DECREASE IN FLOW RATE OF AIR DISCHARGED FROM BLOWER
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.
TECHNIQUE FOR SUPPRESSING MOTOR FAILURE IN BLOWER
A blower in one aspect of the present disclosure includes: a housing including a suction port and a discharge port; a motor in the housing; a fan in the housing; a motor drive circuit; and a control circuit. The control circuit detects an insufficient airflow from the suction port to the discharge port based on an operation parameter. The operation parameter is associated with an operation of the motor.
Rapid inflating and discharging device for protective suit and intelligent multi-purpose protective suit comprising same
The present invention relates to an rapid inflating/deflating device used for a protective clothing and a smart protective clothing, the inflating/deflating device including: an outer cylinder provided with a first hole; an inner cylinder provided in the outer cylinder and provided with a second hole and being capable of sliding between a first position in which the second hole is aligned with the first hole and a second position in which the second hole is deviated from the first hole and is closed by the inner wall of the outer cylinder; a blade provided in the inner cylinder and a motor driving the blade; a biasing device for biasing the inner cylinder toward the first position; wherein the inner cylinder further comprises a third opening on which an one-way valve is provided so as to allow pressurized gas to flow one-way.
Neck fan
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.
Portable blower assembly
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.
MISTING FAN
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.
CORRUGATED TUBE FOR BLOWER AND BLOWER
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.
HEAD MOUNTED FAN
A head mounted fan includes: a main blowing tube configured to be mounted on an upper portion of a head of a user, the main blowing tube having an air inlet through which air is introduced and including a main flow path through which air flows therein; a sub blowing tube connected to the main blowing tube, wherein the sub blowing tube includes a plurality of sub flow paths branching from the main flow path to extend in one direction of the head when the head mounted fan is worn on the head, and wherein air is discharged toward a scalp of the head through a plurality of air outlets communicating with the sub flow paths; and a wind generating unit configured to provide air pressure for causing the air to flow in the main flow path.
CONTROLLING VIBRATION TRANSMISSION WITHIN INFLATION ASSEMBLIES
A housing defines a housing interior. An air pump is within the housing interior. A first set of dampers supports the air pump within the housing. The first set of dampers at least partially isolates vibration of the air pump from the housing. A second set of dampers is configured to at least partially isolate vibration of the air pump from the housing. The second set of dampers arranged in series with the first set of dampers.
