Description
The solid of rotation electric fan is a kind of novel electric fan.
General electric fan all contains blade, motor, fixed base, and wherein blade and motor constitute the electric fan main body, and fixed base is a supporting portion.During electric fan work blowing, gas has reaction force to blade, produces a moment opposite with the motor power square.If as a mechanical system, then this moment is moment of face with the parts of blade, motor and fixed electrical machinery, the magnetic torque of motor is a moment of resistance, make mechanical system in the axial equalising torque of motor, and must have moment of face to make the moment summation in addition is zero.General all is with fixed base the restraining moment of this mechanical system to be come balance.
General electric fan can only back and forth shake blowing in a not too big angular range, being limited in scope of blowing.Shaking by a cover mechanical transmission structure of electric fan realizes, is between fixed base and electric fan main body mechanical transmission structure to be housed, and the power of drive motor shakes the electric fan main body.Obviously, this cover mechanical transmission structure more complicated is made inconvenient maintenance.Shake and the mechanical transmission structure of electric fan main body also will consume certain power.By increasing the length of blade, though can enlarge the blowing scope of electric fan, effect is not remarkable, and need correspondingly increase the power of motor.Owing to the restriction on the general electric fan general structure, its auxiliary function is few in addition, and the ability of decorative environment is not enough.
Under the prerequisite that does not increase power of motor, enlarge the blowing scope of electric fan, produce the effect of a burst of natural wind, mode is that the main body of electric fan is moved preferably, constantly changes blowing position and aspect.When making the electric fan main body when a certain axle rotates, can continuously change the position and the direction of blowing, produce above-mentioned effect.
The electric fan main body is around a certain axle rotation, and the solid of rotation of electric fan rotation just must have the moment that makes its rotation.So, how to utilize gas to the countertorque that blade produces, overcome spin friction moment and resistance of air square, the solid of rotation that drives electric fan rotates.The way of restraint that this just needs to change general electric fan makes not produce the restraining moment that balances each other with the countertorque on the blade.Just to make a kind of new structure of the overall formation of electric fan,, form the solid of rotation electric fan so that utilize the countertorque on the blade.
The solid of rotation electric fan of this new structure contains several parts such as fixed base, swivel mount, motor, blade, sliding conduction structure, and is the same with general electric fan, and the rotor by blade and motor is connected blade and motor formation electric fan main body.Electric fan main body and swivel mount link together, and constitute solid of rotation.General connection can be fixedly connected, also can be the connection of adjustable mutual alignment.Swivel mount combines with bearing with fixed base, and (bearing can be a sliding bearing, also can be rolling bearing), just fixed base is that only to allow swivel mount be that the center rotates freely with the axle (axle of the bearing between fixed base and the swivel mount) of bearing to the constraint of swivel mount.The electric fan main body just can change around the axle rotation of bearing has dried position and direction.Make the countertorque on the blade at the axle direction of bearing moment of components be arranged, electrical axis must parallel or one-tenth space acute angle with the axis of bearing.During the parallel axes of electrical axis and bearing, between the two axial lines segment distance will be arranged, generally can be the length greater than blade.When two axial lines became the space acute angle, angle generally can be very big.Such structure just can utilize countertorque on the blade at the axial moment of components of bearing, overcomes the spin friction moment and the resistance of air square of solid of rotation, forms the solid of rotation rotation.
For to motor and other electrical equipment conducting ABAP Adapter, fixed base is equipped with electrical insulator, and the shape of electrical insulator can be cylindrical circular, and the electrical insulator hoop has the feed slip ring, the axis conllinear of feed slip ring center line fundamental sum bearing.Swivel mount is equipped with brush.General swivel mount can have brush spring, and brush spring is equipped with brush.Brush contacts with the feed slip ring, forms the sliding conduction structure, works to present ABAP Adapter.
The rotating speed of solid of rotation will be controlled to some extent, and for this reason, the swivel mount of solid of rotation electric fan or fixed base can be equipped with frcition damper.Frcition damper can be existing existing products, but also otherwise designed.Utilize the pivoting friction torque that changes between fixed base and the solid of rotation, reach the rotating speed of control solid of rotation.
The negative ion disperse that negative ion generator sends can make with the fresh airly in air, and negative ion is airborne " vitamin ".The swivel mount of solid of rotation electric fan can be equipped with negative ion generator, and negative ion generator adopts existing product to get final product.By means of flowing of air, the rotation of swivel mount, negative ion is diffused in the air soon equably, and air is played good Qinghua effect.
The solid of rotation electric fan has enlarged the blowing scope effectively under the identical condition identical with blade dimensions of power of motor, avoided having produced the effect of a burst of natural wind in the wind-force location set.The solid of rotation fan structure is fairly simple, is convenient to make, use and keep in repair.Also can adorn some supplementary equipment simultaneously, increase function, a fan to be used.Because the general relatively fan structure of solid of rotation electric fan has very big change, makes the electric fan general shape that great changes arranged.According to its specific structure: can make the outward appearance of tool handicraft article character, enjoying value is arranged, play a part to beautify the environment.
The solid of rotation electric fan is in reality is made, and except that swivel mount, fixed base, sliding conduction structure designed on demand, other component adopted the standard parts and components of electric fan industry substantially.Swivel mount, fixed base can be multiple shapes, and this can design according to different situations.The solid of rotation electric fan can be diversified form, and what relatively be suitable for is the solid of rotation ceiling fan.
Accompanying drawing has been represented a kind of structural representation of solid of rotation ceiling fan.
