Abstract
A non-polluting firecracker device having a plurality of firecracker units in a manner that each two form one set respectively strung on a major power lead, whose upper end extends into a control box where it connects with the sound-and-light circuit of a PC board thereof. Each firecracker unit consists of a firecracker-shaped casing through which light can penetrate and a small flash bulb in it. As the circuit is energized, there will be continued firecracker bursting sounds and, in the meantime, flashes sent out from bottom to top in an orderly, repeated way. This way, the same effects of letting off firecrackers are obtained but without generating trash and noxious gases. In addition, it may be used repeatedly to save money.
Claims2
A non-polluting firecracker device comprising a control box;
- a sound and light control circuit in said control box;
- sound producing means to produce firecracker bursting sounds connected to said sound and light control circuit;
- a power lead with positive and negative poles extending into said control box and connected to said sound and light control circuit;
- a plurality of firecracker units in sets of two with each said set of two strung in series with said other sets along said power lead;
- each said firecracker unit including
- a casing in the shape of a firecracker formed of a plastic through which light penetrates,
- a flash bulb within said casing having one lead connected to said positive pole and another lead connected to said negative pole of said power lead;
- said sound and light control circuit including
- sequential means to fire said sets in sequence along said power lead in a direction toward said control box upon energization of said control circuit in accompaniment with firecracker bursting sounds from said sound producing means.
