Abstract
The utility model relates to a multifunction AC/DC fan including a fan casing, a fan blade, a wind guiding fence, a DC motor, a speed governor, a timer, a multilevel transformer, a circuit controls switch, etc. The multifunction AC/DC fan is characterized in that: it is formed by the combination of the DC fan motor and the multilevel transformer. Thus, the function of the AC rotating blade fan is retained and a multilevel speed control can be realized by using a DC motor with a voltage of 3-12 V and a power of 2-12 W or adopting a miniature storage battery for providing power. Otherwise, it can be used as a charger for many kinds of storage batteries.
Description
Technical field
The utility model relates to a kind of multi-functional alterating and direct current fan, particularly a kind of multi-functional alterating and direct current fan that adopts multistage transformer and direct current motor to combine.
Background technique
It is various in style to exchange blade-rotating electric fan in the market, uses but be limited in the place that civil power is arranged.DC electric fan is only limited at the vehicle that DC electrical source is arranged and uses, and the DC electric fan on the market is commonly shortcomings such as power consumption is big, noise is big.Present short of electricity in all parts of the country, the situation of rationing the power supply are comparatively serious, are to be necessary very much for make a multi-functional electric fan that can saving power can use again when having a power failure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency and a kind of multi-functional alterating and direct current fan that provides, it has kept the original function of Ac fan has also increased the multistep speed regulation function outward, can adopt household small-size storage battery, motorcycle storage battery, the power supply of common battery light, also can be used as the charger of each model storage battery simultaneously.
The utility model can realize that multi-functional alterating and direct current fan is made up of fan hub, wind guiding grid, fans, direct current motor, time switch, voltage transformation switch, speed control switch, charger and electric fan alteration switch, charging indicator light, DC electrical source input line, ac power supply input line, charging out-put supply line, element storehouse, multistage transformer by following measure.Wind guiding grid is driven and can be swung by wind-force.Fan motor adopts 2～12 watts of direct current motors, by 12 volts and 12 volts of following storage batteries and 220 volts of AC-powered.In addition this fan also can be respectively after 220 volts of transformations to charge in batteries such as 3 volts, 6 volts, 9 volts, 12 volts.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is multi-functional alterating and direct current fan plan view, 1 fan hub, 2 wind guiding grids, 3 fans, 4 direct current motors, 5 time switches, 6 voltage transformation switches, 7 speed control switchs, 8 chargers and electric fan alteration switch, 9 charging indicator lights, 10 DC electrical source input lines, 14 multistage transformers.
Fig. 2 is multi-functional alterating and direct current fan rear view, 11 ac power supply input lines, 12 charging out-put supply lines.13 element storehouses.
Embodiment
Fig. 1 and Fig. 2 are respectively multi-functional alterating and direct current fan plan view and rear view. and this multi-functional alterating and direct current fan is a kind of table fan, and fan hub 1 is made of plastics the fan upper half part for circular, and the lower portion is the bracker fan shell of shelf bracket.Direct current generator 4 in the multi-functional electric fan adopts 3～12 volts, 2～12 watts direct current motor. and 3 volts, 6 volts, 9 volts, 12 volts voltages of voltage transformation switch 6 may command, also can adopt the voltage transformation switch to control the rotating speed of electric fan simultaneously.The conversion work of multistage transformer 14 and electric fan alteration switch 8 may command electric fans and charger, charging indicator light is opened in charging process simultaneously.Described element storehouse 13 is tetragonal bodies, is to be used for placing elements such as ac power supply input line 11, charging out-put supply line 12.
