Abstract
The utility model discloses an electric fan capable of adjusting oscillating angle, a timer is connected with an input terminal of a microprocessor, an output terminal of the microprocessor is connected with a reversing drive circuit used for driving direct-reverse direction switching of oscillating motor. an optoelectronic switch used for judging whether a head of the electric fan is at a direct position is connected with the microprocessor. The electric fan capable of adjusting oscillating angle can flexibly adjust oscillating angle of the electric fan.
Description
Technical field
The utility model relates to a kind of electric fan of adjustable panning angle.
Background technique
Existing electric fan with the function of shaking the head, the angle of shaking the head (about 180 degree) is fixing, so the people is too much the time, existing this panning angle not enough, and the people is very few the time, also there is waste in this angle of shaking the head, therefore, existing electric fan flexibility with the function of shaking the head is not enough.
The model utility content
The utility model wants the technical solution problem to provide a kind of electric fan of adjustable panning angle, the angle that the electric fan of this adjustable panning angle can the free adjusting electric fan oscillating.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be:
A kind of electric fan of adjustable panning angle, timer is connected with the input end of microprocessor, the output terminal of microprocessor be used to drive the commutation drive circuit that the head-shaking motor positive and negative direction switches and be connected.
Whether the head that is used to judge electric fan is connected with microprocessor at the optoelectronic switch of forward position.
The beneficial effects of the utility model:
The electric fan of adjustable panning angle of the present utility model, adopt timer to regulate the panning angle of electric fan, adopt commutation drive circuit (as the circuit that changes power phase etc.) to realize the switching of forward and reverse rotation of head-shaking motor, realize simply, and solved the nonadjustable problem of existing electric fan oscillating angle well.Therefore, the electric fan of this adjustable panning angle can offer convenience for the people's life.
Description of drawings
Fig. 1 is electric theory diagram of the embodiment 1.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Embodiment 1:
As shown in Figure 1, a kind of electric fan of adjustable panning angle, timer is connected with the input end of microprocessor, the output terminal of microprocessor be used to drive the commutation drive circuit that the head-shaking motor positive and negative direction switches and be connected.Whether the head that is used to judge electric fan is connected with microprocessor at the optoelectronic switch of forward position.
The commutation drive circuit is the mature technology of related domain, as the direction that changes field current etc.
Optoelectronic switch realizes that whether head in a kind of implementation method that forward position detects is: a reflector plate is installed on the head of rotation, forward position at the bearing of electric fan is installed optical transceiver, when head rotates to forward position, reflector plate reflects back the light that optical transceiver sends, and optical transceiver can judge that promptly head has rotated to forward position after receiving this reflected light.The extensive use on the reflective motor speed measuring instrument of light of this technology.
The working principle explanation:
Panning angle is divided into 3 retainings, and it is converted into the cycle of shaking the head (because the angular velocity of shaking the head is fixed), be respectively as 3 cycles: 20s, 40s and 60s.With 20s is example, when electric fan oscillating during to the forward position of electric fan, starts timer, and the counterrotating of microprocessor control head-shaking motor rotates to forward position again after 5 seconds again after 5 seconds, restarts timer, moves in circles according to this.The gear of shaking the head adopts manually or remote control is provided with.
Claims (2)
1. the electric fan of an adjustable panning angle is characterized in that, timer is connected with the input end of microprocessor, the output terminal of microprocessor be used to drive the commutation drive circuit that the head-shaking motor positive and negative direction switches and be connected.
2. the electric fan of adjustable panning angle according to claim 1 is characterized in that, is used to judge that whether the head of electric fan is connected with microprocessor at the optoelectronic switch of forward position.
