Description

A kind of collection acoustic control temperature control self adaption is sought the human body fan

Technical field

The utility model relates to a kind of electric fan, especially relates to a kind of collection acoustic control temperature control self adaption and seeks the human body fan.

Background technique

Electric fan is a kind of device that orders about air flows, when indoor air flows, just can promote the evaporation rapidly of sweat.The body surface of human body has a large amount of sweat, and when electric fan was worked, evaporation was accelerated, because evaporation need absorb a large amount of heats, so people can feel nice and cool.Structure and working principle by electric fan know that the critical piece of electric fan is a Wechselstrommotor.The working principle of motor is that hot-wire coil is stressed and rotate in magnetic field, and the reformulations of energy is that electric energy mainly is converted into mechanical energy, simultaneously because coil has resistance, so inevitably some electric energy will be converted into interior energy.The kind of domestic electric fan has ceiling fan, desk fan, stand fan; The branch of shaking the head He do not shake the head is arranged, the rotary blade fan that also has in the desk fan again; Have in the stand fan shake the head, blade-rotating.Also having the little electric fan of a kind of gentle breeze, is to be hung in specially in the mosquito net, sleep in evening in summer, and a gentle breeze is blowing immediately once opening it, the feel of can sleeping restfully.

At present, electric fan market should be comparative maturity, and in vast city and the part rural area all be to have used cooling such as air-conditioning chiller plant, but electric fan is because of its cheap price, good adaptive capacity to environment, superior performance, still in occupation of the bigger market share.By to the consulting of related data, main patent database, the technology or the idea that are used in electric fan at present are very strange, and be also of common occurrence for the electric fan of temperature control, acoustic control.What for example General Electric Apparatus Co.(U.S.A.) developed a kind ofly is equipped with the miniature electronic receiver with the acoustic control electric fan, only needs clap hands continuously 2 times in the place that is no more than 3m, and electric fan will turn round automatically; If clap hands continuously 3 times, electric fan is stall automatically again again.Toshiba Corp has released a kind of fuzzy micro-control electric fan, and this fan is provided with near gale amounts such as strong, common, weak, can select best air-supply automatically according to the temperature of sensor determination.The technology with self adaption regulatory function as for other also emerges in an endless stream, and also is not quite similar with the used technology of a kind of function, is to develop towards hommization, intelligentized direction on the whole.

Summary of the invention

The purpose of this utility model provides a kind of collection acoustic control temperature control self adaption and seeks the human body fan.

The utility model is provided with fan main body and control circuit, described control circuit is provided with speech transducer, temperature transducer, infrared sensor, microprocessor, motor relay, loudspeaker and display screen, the output terminal of speech transducer, temperature transducer and infrared sensor connects the input interface of microprocessor respectively, the input end of motor relay, loudspeaker and display screen connects the output interface of microprocessor respectively, and motor relay is connected with the motor of fan main body.

Described speech transducer can adopt the quick core silicon sensor of MIC.Described temperature transducer can adopt DS18B20 single line temperature transducer.Described infrared sensor can adopt pyroelectric infrared sensor.Described microprocessor can adopt Ling Yang single-chip microcomputer (including speech processing module).Described display device can adopt light-emitting diode display.

Because the utility model is provided with speech transducer (especially adopting the quick core silicon sensor of MIC), therefore can receive the voice that people send, as " starting fan ", " fan stops ", " heat ", " awfully hot ", " very hot " etc., carry out pattern recognition, thereby sound signal is made a response, i.e. sound control starts, stops, gear selection etc.; This function also can realize the voice self-teaching simultaneously, can carry out the memory and the compression of sound and handle, and has realized the setting of pattern.Satisfying amusement and the pastime function that provides certain under the situation of people to the fan functionality basic demand.

Because the utility model is provided with temperature transducer (especially adopting DS18B20 single line temperature transducer) and LED display, therefore not only can showing temperature, and can change self-starting with ambient temperature, stop, gear shift, sensitivity is higher.According to using effect, this function is best human body night's rest stage Use Limitation fruit, both can save electric energy, can avoid human body excessive blowing and falling ill in sleep procedure again, embodies the human oriented design of machine.

Because the utility model is provided with infrared sensor (especially adopting pyroelectric infrared sensor), therefore can judge whether human body exists, realize the function of " closing when the people walks; people Lai Shikai ", automatically the human body blowing around seeking, with the human body be the center around rotations of shaking the head among a small circle, both avoided traditional electrical fan (desk fan) to rotate the energy charge that causes on a large scale, satisfied the comfort level requirement of human body again to the fan rotation.The pattern of this function can be provided with.

This shows that it is the electronic control system of one that the utility model has been concentrated functions such as acoustic control, temperature control, self adaption searching human body, has solved following technical problem:

1) on technology realizes, adopt the mode of the unified control of Ling Yang single-chip microcomputer, sensor acquisition to information all import single-chip microcomputer, handle according to the program that is written into by single-chip microcomputer, realize software control hardware.

2) the single-chip microcomputer input output are the light current about 5V, and that the fan work use is civil power 220V, how to realize that light current control forceful electric power is a problem, the utility model selects to use relay to realize, single-chip microcomputer output 5V voltage connects relay by relay drive circuit and makes coil produce electromagnetic effect, and magnetic force overcomes spring force, make the inner 220V switch of relay point of contact contact line conduction.

3) because the pyroelectric sensor output voltage that adopts is lower, do not reach the problem that requires of single-chip microcomputer input voltage 5V.The utility model can utilize the gating circuit of 5V of overlap joint such as triode, resistance, diode, when pyroelectric sensing exists less than human body, and output 5V high level.

4) data transmission between various sensors and the main frame, the limited IO resource of single-chip microcomputer satisfies the data input and output of numerous kinds etc. simultaneously, needs programming to make the compatible work of each components and parts.

The utility model is on the hardware foundation of an existing electric fan, the quick core silicon sensor of MIC, DS18B20 single line temperature transducer and the pyroelectric infrared sensor selected for use, by the main frame of Ling Yang single-chip microcomputer as system, make judgement according to the various sensor signals that receive, control the relay and the relevant components and parts of different gears, thereby reach the purpose of control fan.
