Detailed Description

The prior art has the problem that electronic fireworks are discarded to cause resource waste or battery replacement operation is troublesome. Therefore, the present invention provides a new solution, and for a clearer representation, the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1-2, an electronic fireworks granule that wireless charging in area, including the fireworks body and transparent soft colloid 1, the fireworks body is arranged in the transparent soft colloid 1, the fireworks body includes light emitting device 2, is used for detecting MEMS sensor 3, the wireless receiving coil that charges 4, chargeable power supply 5 and the main control chip 6 of fireworks granule position, light emitting device 2, MEMS sensor 3, the wireless receiving coil that charges 4, chargeable power supply 5 all with the main control chip 6 electricity is connected.

The external wireless power supply transmitting device is connected with a power supply, the charger is activated by the quick charging unit to output voltage inside the device, and the wireless power supply chip is driven to work, so that wireless electromagnetic signals are transmitted; and the wireless charging receiving coil 4 in the electronic firework particle receives the electromagnetic signal to complete the wireless charging process.

The firework body is equipped with PCB circuit board 7, is equipped with connecting circuit on PCB circuit board 7, connecting circuit includes basic circuit and current-limiting protection circuit, luminescent device 2, MEMS sensor 3, wireless receiving coil 4 and main control chip 6 of charging all install on PCB circuit board 7, PCB circuit board 7 is equipped with positive electrode piece 9 and negative pole electrode piece 8, but the positive negative pole of rechargeable power supply 5 respectively in positive electrode piece 9 and negative pole electrode piece 8 are connected.
