Description
Technical field
The utility model relates to a kind of alterating and direct current fan, especially relates to a kind of switching power circuit of electric fan.
Background technology
The kind of electric fan is a lot, and desk fan, ceiling fan, console mode fan, ventilating fan or the like are arranged.Traditional electric fan mostly is to utilize alternating current as power; Under the situation in short supply of electricity consumption at present, particularly often needing has a power failure makes the electric fan of power supply to the alternating current that uses 220V, and one meets and has a power failure; Electric fan just can not use, and brings very inconvenience for worker, agricultural production and people's life.
Summary of the invention
The purpose of the utility model is to be directed against the defective that above-mentioned alternating current electric fan is produced under the more situation that has a power failure at present, and a kind of switching power circuit that under power-off condition, can use direct current to replace the AC/DC electric fan of power is provided.
For achieving the above object, the utility model has mainly adopted following technical scheme to realize.The utility model mainly is made up of the Switching Power Supply on the electric fan; Described Switching Power Supply is provided with the alternating electron transformer part; The alternating electron transformer part connects the diode rectification parts, and the diode rectification parts connect relay control switch and direct-flow storage battery.Relay control switch is connected electric fan respectively with direct-flow storage battery, also is provided with power connection on the Switching Power Supply.
The utility model compared with prior art has following obvious advantage.(1), reasonable in design, efficient is high.The utility model converts the alternating current of 220V to direct current to it with Switching Power Supply, and then drives electric fan work with direct current machine.(2), save the energy.The utility model converts direct current to through interchange, and in use, the conversion of the electric energy of direct current machine is higher than AC energy.(3), easy to use, can solve the big problem of the fan that has a power failure.The purpose of the utility model when design is to the dual-purpose problem of AC and DC electricity particularly there is not the present situation of alternating current to having a power failure, so it uses easily, when civil power is arranged, uses alternating current; During power failure, use the direct-flow storage battery that has charged.
The utility model is applicable to electric fan.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Description of drawings
Accompanying drawing is the circuit of the utility model Switching Power Supply.
Embodiment
As shown in the figure; The described Switching Power Supply of the utility model is by being provided with alternating electron transformer part 2; The diode rectification parts 3 that are connected with alternating electron transformer part 2 and 4 compositions of relay control switch that are connected with diode rectification parts 3; Also be provided with direct-flow storage battery 6 on the Switching Power Supply, relay control switch 4 is connected electric fan 5 respectively with direct-flow storage battery 6.Also be provided with power connection 1 on the Switching Power Supply.Embodiment is following; When coming civil power, relay control switch 4 gets electric, gives electric fan 5 power supplies by AC-DC; During power failure, relay control switch 4 dead electricity give electric fan 5 power supplies by direct-flow storage battery 6.
The utility model is applicable to electric fan.
Claims (2)
