Abstract
The utility model relates to an AC-DC dual-purpose emergency electric fan, comprising a body, a machine head, vanes, a protection screen and an AC power cord; the machine head is provided with a DC motor, and the body is provided with a transformer and a rectifier circuit. The utility model is characterized in that the AC-DC dual-purpose emergency electric fan is also provided with a DC power cord, one end of the DC power cord is provided with a power plug, and the other end passes through the DC output terminal in-connected with the rectifier circuit in the body. The AC-DC dual-purpose emergency electric fan can use other standby DC power supply to work when city power is off, such as emergency light power.
Description
Technical field: the utility model relates to the emergent electric fan of a kind of AC/DC.
Background technique: along with the economic development of China, the raising of living standards of the people, all trades and professions and daily life power consumption are anxious to be increased, and power construction goes to lag behind out and away, the electric power breach is huge, and therefore power failure phenomenon in all parts of the country in recent years is serious day by day, and resident's daily life also is affected.Many for this reason families all have an emergency lamp, these flare-up lights can provide the temporary lighting of certain hour for us when having a power failure, and be provided with a DC electrical source accessory power outlet for other small-sized DC electricity consumption use, and present employing interchange provides the direct current electric fan of working power all only to establish an interchange input line through depressurization and rectification, so can't utilize the power supply in the flare-up light when having a power failure, this is to be difficult to stand in the more frequent summer that has a power failure really.
Summary of the invention: the purpose of this utility model is can utilize other standby DC electrical source when overcoming the deficiencies in the prior art a kind of mains failure is provided, as the emergent electric fan of the AC/DC of flare-up light power supply.
The above-mentioned purpose that is achieved through the following technical solutions of the present utility model: a kind of AC/DC electric fan of meeting an urgent need, comprise fuselage, head, blade and protection net and AC power cord, be provided with direct current generator in the head, be provided with transformer and rectification circuit in the fuselage, it is characterized in that: the emergent electric fan of described AC/DC also is provided with a direct current supply line, described direct current supply line one end is provided with power plug, and the other end penetrates the dc output end that is connected rectification circuit in the fuselage.
Because electric fan is provided with a direct current supply line in addition, external dc power directly can be introduced into the dc output end of electric fan rectification circuit, be the motor power supply, therefore when mains failure, only need the plug of direct current supply line is inserted on the flare-up light accessory power outlet, the storage battery in the flare-up light just can provide interim power supply for electric fan.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings:
Accompanying drawing 1 is the utility model embodiment schematic representation;
Accompanying drawing 2 is the utility model circuit theory diagrams.
Specific embodiment: as shown in the figure 1,2, the emergent electric fan of AC/DC still includes fuselage 1, head 2, blade 3 and protection net 4, direct current generator is arranged in the head, step-down transformer and rectification circuit are arranged in the fuselage, AC power cord 5 passes from fuselage 1 rear side, switch is arranged on fuselage 1 upper surface, direct current supply line 6 also passes (can certainly establish a cable-through hole in addition) from same hole, in terminate at the direct current outlet side of rectification circuit, the outer end is provided with a common pin with injection molding way, as RCA connector or other form power plugs, preferably select for use with flare-up light in the plug form that matches of the most frequently used socket.
