Abstract
The utility model relates to an oscillating angle adjustor for an electric fan, pertaining to the technical field of electric fan. The technical problem to be settled is to provide an electric fan oscillating angle adjustor with safe operation, easy angle adjustment and reliable quality. A lead screw (4) is connected with a connecting piece (8) by thread; the lead screw is supported by the wall of a box-body (3); the other end of the lead screw is connected with an electric motor (5); the electric motor is located by the box body; a rail cover-plate (7) is fixed on the bottom surface of the box body; the other end of the connecting piece is extended out of the rail hole arranged on the rail cover-plate. The angle adjustor is mounted on the oscillating gear of an oscillating control mechanism, and the end of the connecting piece extended out of the rail cover-plate is connected with one end of a connecting rod connected with an angle scale.
Description
Technical field
The utility model relates to the electric fan oscillating angle device, can regulate the panning angle of fan easily.
Background technique
Existing electric fan oscillating mechanism all is that reducing gear is arranged basically, and quadratic crank mechanism and control mechanism three parts are formed.One of them drive connecting rod in the quadratic crank mechanism is converted into the reciprocally swinging of two driven rocking bars, realizes the action of shaking the head of fan.Regulate the length of rotating lind rod, just can realize regulating the panning angle of fan.Scheme is Chinese patent application 200520077229.1 " rocking angle regulator for electric fan " the most simply and easily at present, connecting rod is made screw rod with regulator and nut cooperates, manual rotary screw, the position of the adjusting nut and the centre of location, just can regulate rotating lind rod length, realize regulating the panning angle of fan.This mechanism must open the bonnet of fan, and ability is rotary screw manually, and this adjusting was both dangerous, and is also inconvenient, and each the adjusting all will be opened bonnet, do not have market value.
Summary of the invention
Model utility technical problem to be solved is: use motor to replace manual rotary screw, the motor that utilizes carbon brush to cooperate with slip ring to solve in the rotation gets electric problem, thereby the rocking angle regulator for electric fan that a kind of safer, easy accent, mechanism are simple, can regulate arbitrarily in 0～130 degree angular range is provided.Its technological scheme is: its mechanical technique main points are: screw mandrel (4) is threaded with link (8), screw mandrel is supported by solid of rotation (3) wall, the screw mandrel the other end connects motor (5), solid of rotation positions motor, one side of solid of rotation is fixed with track cover plate (7), and the other end of link stretches out from the orbit hole that the track cover plate is provided with.This angle demodulator is installed on the panning gear of the control mechanism of shaking the head, and its end that stretches out the link of track cover plate is connected with an end of the connecting rod of angle of attachment scale.The control technique main points are: send increase or less panning angle signal by remote control, load onto circuit board for receiving at electric fan, accepting circuit conversion is the clockwise and anticlockwise driving voltage of motor, the electric wire (13,14) that circuit board for receiving sends positive and negative rotation circuit is connected with the carbon brush (9,12) of secured adjusted device seat, two slip rings (10,11) are installed in central shaft outside at solid of rotation, carbon brush contacts with slip ring, and slip ring connects motor by electric wire.Compared with prior art its technique effect is: send increase or less panning angle signal by remote control, receiving circuit is converted to the clockwise and anticlockwise driving voltage of motor, clockwise and anticlockwise by carbon brush, slip ring realization motor drives the threaded connector move left and right, makes link drive the angle scale location by connecting rod, can in the scope of 0-130 degree, regulate the panning angle of fan head arbitrarily, both safe and reliable, easy to use flexible, and simple in structure, cheap, be convenient to install.Conveniently on existing electric fan, install and use.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is carbon brush and slip ring structure enlarged view.
Fig. 3 is the schematic representation of control circuit.
Embodiment
As shown in Figure 1: this panning angle regulator is made up of the connecting rod 1 of angle of attachment scale, regulator base 6, panning gear 2, solid of rotation 3, screw mandrel 4, motor 5, track cover plate 7, threaded connector 8, two 9,12 and two slip rings 10,11 of carbon brush, and 13,14 for drawing electric wire.Screw mandrel 4 is connected with threaded connector 8, screw mandrel is supported by solid of rotation 3 lower walls, and the screw mandrel the other end connects motor 5, and solid of rotation positions motor, the bottom surface of solid of rotation is fixed with track cover plate 7, and the other end of link stretches out from the orbit hole that the track cover plate is provided with.This angle demodulator is installed on the panning gear of the control mechanism of shaking the head, and its end that stretches out the link of track cover plate is connected with an end of the connecting rod of angle of attachment scale.As long as the clockwise and anticlockwise of control motor just can drive the screw mandrel rotation, thereby change the panning angle of fan.
As shown in Figure 2: carbon brush 9,12 is fixed on the regulator base 6, and pressurizeing with spring in the back, and draws electric wire respectively, slip ring 10,11 is enclosed within the axle of solid of rotation 3 and goes up and fix, keep in touch with carbon brush 9,12, slip ring 10,11 is drawn electric wire and is connected motor, and motor is powered.
As shown in Figure 3: behind low-voltage dc circuit, provide power supply for receiving circuit from the 220V power supply, receiving circuit is by remote control or directly control on fan panel, output positive voltage or negative voltage, pass through carbon brush and slip-ring device again, the drive motor clockwise and anticlockwise, thus the size that realizes the fan head swinging angle is controlled.
Pin the increase panning angle button of remote control, the motor counter-rotating, screw rod drives the rotating center that threaded connector departs from solid of rotation, and length of connecting rod is elongated, and the panning angle of fan increases gradually, is 130 degree to the maximum; Pin the minimizing panning angle button of remote control, motor just changes, and screw rod drives the rotating center of nut near solid of rotation, and length of connecting rod shortens, and the panning angle of fan reduces gradually, is 0 degree up to panning angle.
