This utility model discloses a core structure for a high-energy ignition coil used in automobiles, including a core structure installed inside the ignition coil housing. The core structure comprises a magnetic sheet, a primary coil, a secondary coil, and a toroidal core. The magnetic sheet is embedded in the primary coil, which is interference-fitted into the secondary coil. The toroidal core simultaneously surrounds both the primary and secondary coils and is tightly fitted to the magnetic sheet. The end of the primary core furthest from the magnetic sheet is tightly fitted against the toroidal core. The closed magnetic circuit structure of the toroidal core concentrates the magnetic field almost entirely within the core, resulting in minimal magnetic leakage, uniform magnetic field distribution, low magnetic reluctance, and high magnetic flux density. This leads to high energy conversion efficiency, minimal energy loss, and the efficient energy conversion capability enables the ignition coil to generate higher secondary voltage and stronger spark energy. It is suitable for lean-burn and high-performance engines, ensuring reliable ignition and better fuel economy.

This invention provides a launcher for launching electronically ignited fireworks, comprising: a positive and negative terminal of each launch tube connected to the positive and negative terminals of the electronic ignition wire on the fireworks, respectively; a power supply control mechanism igniting the fireworks body through the positive and negative terminals; each positive wire in the control cabinet connected to a positive terminal, and each negative wire connected to a negative terminal; and a solar panel supplying power to the control cabinet. By directly connecting the positive and negative terminals of multiple launch tubes to the positive and negative terminals of the electronic ignition wire of the fireworks through a compression connection, the tedious manual wiring process is eliminated, enabling rapid installation of the fireworks. Simultaneously, the power supply control mechanism triggers stable ignition of the fireworks through the positive and negative terminals, avoiding the risk of electric shock from close contact with high-voltage power and the hazard of wire detachment, making the fireworks easy to install, reliable to ignite, and safe to operate.

This utility model discloses a porous media regenerative low-NOx burner nozzle, including a wind box. A tube is disposed on the front side of the wind box, and the back side of the tube is fixedly connected to the front side of the wind box via a first bolt. A heat-conducting pipe is disposed on the outer arc surface of the tube, and a heat-conducting grid is disposed at the bottom of the front side of the wind box. Both ends of the heat-conducting pipe are fixedly connected to the front side of the heat-conducting grid. This utility model provides a porous media regenerative low-NOx burner nozzle that effectively utilizes the high-temperature flue gas generated during combustion to preheat the air entering the wind box. The preheated air temperature is significantly increased, promoting fuel-air mixing and combustion efficiency, and avoiding incomplete combustion caused by low inlet air temperature. This not only improves thermal energy utilization and reduces fuel consumption but also helps reduce the generation of nitrogen oxides, meeting the environmental protection requirements of energy conservation and emission reduction, and is suitable for high-temperature equipment such as industrial furnaces and kilns.
