Introduction of the working principle: as shown in fig. 2, an apparatus for supplying power by using a backup power source at the time of sudden power failure by using an electromagnetic induction technology is provided. An anti-power-off circuit X is connected in parallel with the original circuit of the electrical appliance 5 which needs to be prevented from power failure, the electrical appliance 5 which needs to be prevented from power failure is supplied with power by 220V alternating current 1, the anti-power-off circuit X and the original circuit of the electrical appliance 5 which needs to be prevented from power failure form a circuit Y together, an electromagnetic coil 6 is connected in series with the original electrical appliance 5 which needs to be prevented from power failure, and a group of levers with two ends respectively provided with a small ball (namely the first small metal ball 7 and the second small metal ball 8) are additionally arranged. The lever structure is shown in fig. 3, and the power failure prevention circuit X is a circuit formed by connecting a 12V lead storage battery 2, a switch, two hemispherical metal conductive grooves 3 (with a certain gap, when the first metal ball 7 contacts with them, a path is formed), and an inverter 4 in series. The lever is located between the X circuit and the solenoid 6 and is not part of the X circuit and the solenoid 6. When the electric appliance is normally powered on, the first small metal ball 7 is attracted by the electromagnetic force of the electromagnetic coil 6 and cannot be contacted with the hemispherical metal conductive groove 3, so that the standby circuit is not powered on. When the external power is suddenly cut off, the electromagnetic coil 6 has no current and can not generate electromagnetic force, the first metal small ball 7 falls down and contacts with the two hemispherical metal conductive grooves 3, and the power failure preventing circuit X forms a passage. At this time, the 12V lead-acid battery 2 (backup battery) starts to supply power, and the dc power supplied from the battery is converted into 220V ac power by the inverter 4, and the power is supplied to the electric appliance for normal operation. And a switch in the power failure prevention circuit X can be used for selectively controlling whether to start the power failure prevention function or not by a user.
For the lead storage battery, a mode similar to that of a storage battery of an electric vehicle is adopted, when the electric quantity of the battery is exhausted, the battery can be charged by adopting a method of an external charging wire, and the multi-time utilization is ensured so as to improve the utilization rate of the battery.
In an exemplary embodiment of the present application, when the switch in the circuit X is closed, if the external power is cut off suddenly, the electrical appliance may not operate normally, and at this time, no current passes through the electromagnetic coil and the electromagnetic force cannot be generated, so that the first metal ball 7 falls down and contacts with the two hemispherical metal grooves, and the circuit X forms a path. At this time, the 12V lead storage battery (backup battery) starts to supply power, and the dc power supplied from the battery is converted into 220V ac power by the inverter and supplied to the electric equipment to operate normally.
When the electric appliance 5 needing power failure prevention is a refrigerator, the fixation of the crank type lever is as follows: a metal shaft perpendicular to the lever passes through the middle point of the lever to fix the position of the lever in the refrigerator.
As shown in fig. 1, at this time, the second metal small ball 8 at the other end of the curved lever 9 rises to contact with the groove of the sound and light alarm module, so that the alarm lamp 11 starts to work, and the GSM device in the GSM device and the electric bell 10 sends a short message to the mobile phone of the owner to inform that the power failure of the electric equipment occurs. Meanwhile, the electric bell rings, the alarm lamp 11 lights, and the electric equipment is informed of power failure.
In another embodiment of the application, when the switch in the circuit x is turned off, the power failure prevention function is suspended, and at the moment, if the electrical appliance is suddenly powered off, the electrical appliance cannot be powered by the standby power supply and cannot give an alarm through the GSM and acousto-optic alarm module.
The invention can control the power supply through the standby power supply to avoid or reduce the loss when the power is suddenly cut off through electromagnetic induction. Electric power has become an indispensable part of life. When the safety of people's life and property is concerned, the function of the power-off preventing device can be fully displayed. In this regard, the device will play an important role in the medical field. The device is applied to various electric driving devices in an operating room, and the life safety of patients can be ensured to a greater extent by devices such as a breathing machine, a monitor and the like in an intensive care unit. In addition, the device is applied to various household appliances, so that the damage to the appliances caused by sudden power failure can be reduced, and the service life of the household appliances is prolonged.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
