The elastic component convenient for holding also is arranged on the pillar as a further improvement of the utility model,.
The utility model has the beneficial effects that
The utility model is placed on the switching power circuit plate of adapter inner inside speed regulation box, is integrally formed, if It sets on pillar and is electrically connected with fan main body, when use is not necessarily to external establishing device, very convenient practical.
Detailed description of the invention
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.
Fig. 1 is the surface structure schematic diagram of the utility model.
Fig. 2 is the principles of the present invention schematic diagram
Specific embodiment
As depicted in figs. 1 and 2, a kind of AC DC dual purpose fan, including pedestal 5, pillar 6, speed regulation box 1 and fan Main body 3, described 6 one end of pillar is connect with pedestal 5, the other end and fan main body 3 connect, which is arranged on pillar 6 simultaneously It is electrically connected with fan main body 3, is integrated with switching power circuit plate 2 in the speed regulation box 1, the switching power circuit plate 2 For ac power input end for connecting external ac power source, the DC power output end of switching power circuit plate 2 can export warp DC power supply after conversion, the design are placed on the switching power circuit plate 2 of adapter inner inside speed regulation box 1, are made into one Integrally, external establishing device is not necessarily to when use, it is very convenient practical.
The DC power output end of the switching power circuit plate 2 is electrically connected with zener diode D1, to guarantee aweather Fan main body 3 exports the DC voltage of stable 15V.
The DC power output end of the switching power circuit plate 2 is also electrically connected with to be set for connecting external dc power Standby interface 4, the DC power supply device can be solar panels, be also possible to battery 8.
Zener diode is also electrically connected between the interface 4 and the DC power output end of switching power circuit plate 2 D2, to guarantee to export the DC voltage of stable 12V-18V to fan main body 3.
The cavity for placing external dc electricity source device is additionally provided in the speed regulation box 1, which, which is generally used for placing, stores Battery 8 is integrated in speed regulation box 1, improves practicability by battery 8.
The elastic component 7 convenient for holding is arranged on the pillar 6, also in order to which user moves fan.
The foregoing is merely the preferred embodiments of the utility model, the utility model is not limited to above-mentioned embodiment party Formula, if with essentially identical means realize the utility model aim technical solution belong to the protection scope of the utility model it It is interior.
