Description

A kind of electric fan
Technical field
The utility model relates to electric fan.
Background technique
Existing fan mainly contains following two kinds of control modes: the one, realize by Manual mechanical; The 2nd, telecontrol uses a teleswitch, first allow fan head swinging, after blade face turns to suitable direction, control again it and stop operating, thereby obtain more appropriate air supply direction, but the bimanualness that above two kinds of modes all depend on people realizes the control to fan, and inconvenience operates.In addition, although mat is installed at blade outward, because child's finger is thinner, still finger can be extend in guard, exist potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of electric fan, can automatically regulate rotating speed and the direction of fan, and Security is better.
Electric fan described in the utility model, comprise fan body, base, head-shaking motor, blade rotation motor and control circuit, described control circuit comprises puocessing module, infrared senor, temperature transducer, range sensor, the control circuit of shaking the head, PWM alignment circuit and power switch circuit, infrared senor, temperature transducer and range sensor are installed on base, and infrared senor, the output terminal of temperature transducer and range sensor is connected with the inlet opening of puocessing module respectively, the described control circuit of shaking the head, the input end of PWM alignment circuit and power switch circuit is connected with the delivery outlet of puocessing module respectively, the output terminal of control circuit of shaking the head is connected with head-shaking motor, the output terminal of PWM alignment circuit is connected with blade rotation motor.
Also comprise warning circuit, this warning circuit is connected with puocessing module.
Described infrared senor is three, is separately positioned on left side, front side and the right side of base.
Infrared senor detects the fan infrared signal of human body around in real time, and gathered infrared signal is passed to puocessing module; Puocessing module is according to infrared signal analyzing positions of indoor persons, and generates control information according to personnel positions, and control information is sent to the control circuit of shaking the head, and the control circuit control fan head swinging of shaking the head is adjusted to the wind direction of fan the position at personnel place.Temperature transducer detects extraneous temperature in real time, and gathered temperature signal is passed to puocessing module, and puocessing module is sent control signal according to temperature signal, controls PWM alignment circuit fan is carried out to speed governing.Range sensor is measured the distance between this fan and people in real time, and measured distance signal is passed to puocessing module, when detect the distance of people and fan be less than or equal to default abstinence apart from time, puocessing module control warning circuit report to the police; In the time detecting that the distance of people and fan is less than or equal to default exposure distance, puocessing module control power switch circuit is cut off the electricity supply.
Electric fan described in the utility model:
One, can guarantee that user all can blow to wind in indoor arbitrary position, in the time that multi-user uses, control fan and on each user's position, stop the identical time for user's blowing, reach the effect that multi-user uses a fan simultaneously, when infrared senor detect indoor nobody time, control fan oneself and enter sleep state, user needn't worry to forget and closes fan and cause electricity consumption waste;
Two, can regulate in real time according to external temperature the wind speed of fan, when people evening in bed, start after electric fan, after temperature declines, control electric fan and reduce wind speed, prevent that people from suffering from cold, when after temperature rise, control electric fan and improve wind speed, guarantee that people can have a good sleep;
Three, Security is good, in the time that individually defined thing (such as child) is less than default safe distance with the distance of fan, controls fan stall and also send alarm sound, thereby effectively preventing that child from pointing stretches into fan and is twisted wound.
Brief description of the drawings
Fig. 1 is the structured flowchart of electric fan described in the utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is described in further detail.
As depicted in figs. 1 and 2, this electric fan comprises fan body 11, base 12, head-shaking motor 6, blade rotation motor 9 and control circuit, described control circuit comprises puocessing module 4, infrared senor 3, temperature transducer 2, range sensor 1, the control circuit 7 of shaking the head, PWM alignment circuit 8, power switch circuit 10 and warning circuit 5, infrared senor 3, temperature transducer and range sensor are installed on base, and infrared senor, the output terminal of temperature transducer and range sensor is connected with the inlet opening of puocessing module respectively, the described control circuit 7 of shaking the head, PWM alignment circuit 8, the input end of warning circuit 5 and power switch circuit is connected with the delivery outlet of puocessing module respectively, the output terminal of control circuit 7 of shaking the head is connected with head-shaking motor, the output terminal of PWM alignment circuit 8 is connected with blade rotation motor.
As shown in Figure 2, described infrared senor 3 is three, is separately positioned on left side, front side and the right side of base 12.Infrared senor 3 detects the fan infrared signal of human body around in real time, and gathered infrared signal is passed to puocessing module 4; Puocessing module 4 is according to infrared signal analyzing positions of indoor persons, and generates control information according to personnel positions, and control information is sent to the control circuit 7 of shaking the head, and the control circuit 7 of shaking the head is controlled fan head swinging, the wind direction of fan is adjusted to the position at personnel place.In the time that infrared senor 3 is responded to the infrared signal less than human body, puocessing module 4 is sent sleep signal and the head-shaking motor 6 of fan and/or blade rotation motor 9 is closed enter sleep state, in the time that infrared senor 3 senses the infrared signal of human body again, puocessing module 4 is sent wake-up signal, makes fan work.In addition, when infrared senor 3 induces around personnel when multiple, puocessing module 4 is sent control signal control fan and is shaken the head, and controls fan and on each user's position, stops the identical time and dry for user.Temperature transducer 2 detects extraneous temperature in real time, and gathered temperature signal is passed to puocessing module 4, and puocessing module 4 is sent control signal according to temperature signal, controls PWM alignment circuit 8 fan is carried out to speed governing.Range sensor 1 is measured the distance between human body in real time, and measured distance signal is passed to puocessing module 4, when detect the distance of human body and fan be less than or equal to default abstinence apart from time, puocessing module 4 is controlled warning circuit 5 and is sent chimes of doom; In the time detecting that the distance of human body and fan is less than or equal to default exposure distance, puocessing module 4 is controlled power switch circuit 10 and is cut off the electricity supply, and also can avoid the generation of accident.
