Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings. The present invention may be embodied in many different forms and is not limited to the embodiments described in the text. Rather, the embodiments are provided so that this disclosure will be thorough and complete.

As shown in the attached figure 1, a multi-functional emergency power generation flashlight, including a barrel shell grab handle, barrel shell grab handle upper end is equipped with the lamp holder, the inside LED lamp that is equipped with of lamp holder, be equipped with the rotating switch in the middle of lamp holder and the barrel shell grab handle, inside drive circuit device, solenoid, the neodymium iron boron magnetism body of being equipped with of barrel shell grab handle, solenoid and the laminating of barrel shell grab handle inner wall, the neodymium iron boron magnetism body can be in the solenoid up-and-down motion, barrel shell grab handle bottom outside is equipped with urgent whistle of seeking survival draw-in groove and urgent whistle of seeking survival, urgent whistle of seeking survival one end is articulated with urgent whistle draw-in groove, be close to lamp holder one end on the barrel shell grab handle outer wall and be equipped with USB output interface, LED lamp and drive circuit device electric connection. The emergency survival whistle can generate high-decibel whistle sound, can attract the attention of surrounding personnel at a critical moment, and can be turned back into the clamping groove when not used. The USB output interface is used for charging the mobile phone with the electric quantity automatically generated by the flashlight, so that the mobile phone can be charged and started and the help can be asked when the electric quantity of the mobile phone is exhausted and other charging equipment does not exist at an emergency.

A smooth cup is further arranged in the lamp holder along the circle of the bulb, and a 15-degree inclined condensing lens is arranged on the lamp holder, so that an LED light source is effectively condensed, and the lighting is more efficient.

The driving circuit device comprises a booster circuit, a rectifying circuit and a super capacitor, wherein the booster circuit, the rectifying circuit and the super capacitor are electrically connected and used for driving the LED to emit light so as to realize illumination.

The boost circuit is a 'Joule thief' boost circuit, comprises a triode, an inductor and a resistor, and is simple in structure.

The rectifier circuit is a rectifier bridge built by rectifier diodes 1N4007, the diode packaging form is a plastic packaging type general silicon material rectifier diode of DO-15, and low-voltage alternating current is rectified into direct current required by the driving circuit device.

The super capacitor is a 5.5V 1.5F Farad capacitor, and has the advantages of high charging speed, long cycle service life, ultra-strong discharging capacity, high energy conversion efficiency and small process loss; the raw materials of the product are pollution-free in the processes of composition, production, use, storage and disassembly, and the product is an ideal green and environment-friendly power supply; the charging circuit is simple, does not need a charging circuit like a rechargeable battery, and is free from maintenance after long-term use.

When the electric torch is used, the lamp cap rotary switch is determined to be in an off position, then the flashlight handle is held by a hand and shaken up and down, after the shaking time lasts for about 20-30 seconds, the rotary switch is turned to an on position, the super capacitor starts to discharge, the Joule thief booster circuit starts to work, the LED lamp is lightened, and illumination is realized. If the mobile phone is connected to the flashlight through the USB output interface at the moment, the flashlight is in a charging mode, and the LED lamp is not on.

The power generation principle is as follows: as shown in fig. 2 and 5, when the magnet is shaken up and down, the ndfeb magnet moves up and down in the solenoid, and the solenoid performs a cutting magnetic induction line motion relative to the ndfeb magnet, so that magnetic flux changes to generate induced electromotive force in the coil, the induced electromotive force is alternating current, and the alternating current is converted into direct current through the bridge rectifier to charge the super capacitor.

Boosting principle: as shown in fig. 3, when the switch is turned on, the feedback coil provides a trigger signal to the base of the triode, so that the collector and the emitter of the triode are conducted, the capacitor starts to supply power to the inductor, the LED is short-circuited, and the current forms a magnetic field on the inductor to charge the magnetic ring.

When the magnetic ring is charged, a magnetic field is formed on the inductor, the feedback coil induces electromotive force, the collector electrode and the emitter electrode of the triode are prevented from being conducted by the electromotive force, and the magnetic field charged by the inductor for the magnetic ring is changed into an electric field and then is serially connected and superposed with the voltage of the capacitor to discharge the LED lamp or the mobile phone connected through the USB output interface. The voltage reaches the working voltage of the LED lamp, so that the LED lamp can be lightened, and the principle of charging the mobile phone is the same as that of the LED lamp.

The boosting principle is completed in one moment, so that the triode is continuously conducted and cut off to generate high-frequency oscillation current, and the LED lamp beads are continuously lightened or charged.

In the above embodiments, all functions may be implemented, or a part of the functions may be implemented as necessary.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
