Abstract
The invention discloses a type of a domestic fan. The equipment adopts a small DC fan for home heat dissipation. Compared with the existing domestic AC fan, the small and portable fan of the invention has the advantages of moderate wind power, varied function, energy saving, low cost and the like. The equipment is divided into three parts of a DC fan body, a circuit, a case and a fixing device and supplies power by mains supply, and a switch power supply outputs adjustable voltage under the control of an integrated circuit integrating with the control function to provide a DC power supply for the DC fan. The control circuit adopts that four keys are matched to control, and the glittering of an indicator light is adopted to indicate the type of wind, wind quantity and timing state. The case serves as the case of the fan and the circuit and is fixed by the fixing device.
Description
Technical field
The present invention is a kind of newtype of family expenses radiation fan.
Background technique
A series of shortcomings such as existing family expenses fan mostly is AC motor and drives the flabellum rotation, because of its overtension, causes wind-force excessive, and fan body is huge, and it is excessive to consume energy.
High voltage causes wind-force excessive: although the fan that has provides designs such as speed governing, yaw, rotation wind direction, but allow the people be difficult to adapt to its wind-force, especially the individual closely uses for a long time, tends to cause the discomfort on some healths.
Fan body is huge: make that carrying inconvenience influences its using scope, and be difficult to realize various new and original appearance designs.
The motor high voltage: cause fan loop on the high side, it is excessive to consume energy, and is unfavorable for economizing on resources and the energy.
Owing to adopt Alternating Current Power Supply, and most of control circuit needs DC electrical source, add additional function to fan and form obstacle, make existing family expenses ac fan be difficult to realize functional diversities.
The technology of Modern Small brushless DC fan is very ripe, has reached seriation, practicability.But mostly existing household DC fan design is to adopt battery or USB power supply, limited because of battery electric quantity, USB interface is restricted, makes to be restricted on fan practicability and the diversity, is difficult to promote.
Summary of the invention
The present invention is directed to existing mentality of designing shortcoming, adopt the small-sized DC fan to be used for family's heat radiation, be divided into circuit part, DC fan main body, housing and support three parts:
Circuit part: civil power is adopted in power supply, and the direct current output of switch power Adjustable Output Voltage under the control of the intergrated circuit of integrated control function provides power supply to DC fan.
The user realizes control by four buttons of fan are worked in coordination.Tutorial light indication fan work state.
The kind of wind is divided normal wind, natural wind and three kinds of states of sleep wind, and every kind of state divides again and often blows and two states regularly; Timing segment length weak point can be adjusted at any time, and outage can be remembered.
Fan main body: adopt the small-sized DC fan that is applicable to family's heat radiation, can select multiple voltage and size.
Housing: be the shell of fan and circuit, and fixed by fixing device.Case design becomes the moulding of various novel and beautiful, and fixing device adopts various ways such as seat formula, clamping, adhesion, suspention.
This household DC fan wind-force is moderate, small volume and less weight, easy to adjust, diverse in function, energy saving, can be designed to various new and original outward appearances, is applicable to that the individual is in family or the outdoor place that commercial power interface is arranged.Fan can be put on the table, the place of the head of a bed and any long-time stop, closely uses for a long time also discomfort can not occur.Be that the structural of existing family expenses radiation fan system replenished.
Description of drawings
Accompanying drawing 1 is the schematic representation of overall circuit;
Accompanying drawing 2 is DC fan schematic representation.
Embodiment
The present invention divides DC fan main body, circuit, housing and support three parts:
DC fan adopts the small-sized DC fan that is applicable to family's heat radiation, can select multiple voltage and size.
Circuit connects power supply unit and control section with specific integrated circuit, as shown in Figure 1.Control circuit touches button by four and a light emitting diode is formed, and they connect specific integrated circuit by lead, and this intergrated circuit is the directly work of the power supply switch tube of control switch power supply in direct-current switch power supply.
Power supply input civil power, PWM (pulsewidth modulation rectification) conversion under rectification and specific integrated circuit control, the VDC of output adjustable size, air feed fan machine operation.The user controls fan by four buttons, and light emitting diode shows the working state of fan by the light and shade conversion.
Control 5 grades of systems, i.e. timing, air quantity, natural wind air quantity and period all are divided into 5 grades.
Control circuit provides the fan power supply overcurrent protection function.
The kind of wind is divided normal wind, natural wind and three kinds of states of sleep wind, every kind of state divides again and often blows and two states regularly, often blows, and promptly is in the opening state of this kind wind all the time, be the opening state that is in this kind wind at limiting time section internal fan regularly, the time finishes the aft-fan stall.
Tutorial light Chang Liang when button not.
The wind class is switched
Be initially normal wind and often blow state, air quantity is a third gear.
Cooperating 1 key arbitrarily to switch by long by 2 keys between three kinds of wind classes, switch the operating method of imitation mobile phone shutdown, is long by, directly switching in case detect, and lamp dodges twice slowly.
Individual palpation 3 or 4 during normal wind, the plus-minus air quantity, fast continuously during button, the short sudden strain of a muscle when pressing, and then show final state.
Lamp dodged according to the air quantity size when air quantity was changed ,-be to dodge slowly. be quickflashing,
1 grade of ..-, 2 grades of .-, 3 grades-, 4 grades-., 5 grades-...
Time control
The timing segment length is short adjustable at any time, and cuts off the power supply and can remember, and can switch between 3 minutes, 5 minutes, 8 minutes, 12 minutes, 20 minutes, is initially five minutes.
Pin 1,, adjust regularly period length, click tutorial light quickflashing twice simultaneously by 3 or 4.
Short in 2, beginning timing, and timing added-time also can add the time, maximum five times of added-time number of times after regularly finishing again.
3,4 keys are short on time dodges, and crossing in limited time, tutorial light does not dodge.
Under the definition status, each finishes lamp time period dodges, dodges five times when the time will be all over, and has dodged the timing end five times.
Natural wind
Long by 2, switch natural wind, normal wind.
Natural wind is at random from a kind of air quantity.
Air quantity is reciprocal according to 503241 sequence period.
Time is reciprocal according to 12132 sequence period, and unit of time is 10 seconds.
For example
Air quantity 502314502314502314502314
Time 121321213212132121321213
Sleep wind
1+2 bond distance is by the switching for sleep wind and normal wind.
Sleep wind is consistent with the method for natural wind, and difference is every about 20 minutes the air quantity rank of successively decreasing, until calm fully.
Housing is the shell of fan and circuit, and is fixed by fixing device.Case design becomes the moulding of various novel and beautiful, and fixing device adopts various ways such as seat formula, clamping, adhesion, suspention.
