Abstract

The invention provides an environment-friendly and safe firework setting-off device. The environment-friendly and safe firework setting-off device comprises a setting-off chamber with an upper cover; the setting-off chamber is a bottom-free hollow cylindrical cavity; through holes are fully distributed in the side wall of the setting-off chamber; a firework storage rack is arranged on the inner wall of the setting-off chamber; the firework storage rack is divided into an upper spiral and a lower spiral hovering in the setting-off chamber; the upper spiral and the lower spiral are shaped like spiral springs; a gap is formed between the upper spiral and the inner wall of the setting-off chamber; the lower spiral is fixedly arranged on the inner wall of the setting-off chamber; the upper spiral and the lower spiral are fixedly connected through a connector; an upper setting-off opening is formed in the upper cover. The environment-friendly and safe firework setting-off device provided by the invention has the advantages that the fireworks are set off inside the setting-off chamber and cannot cause injury to surrounding people and environment; the spiral firework storage rack is adopted, so the inner space utilization rate of the firework setting-off device is improved; setting-off openings are arranged on the upper and lower sides of the setting-off device, so that the setting-off efficiency of fireworks is improved.

Description

technical field [0001] The invention belongs to the technical field of firecracker setting devices, in particular to an environment-friendly and safe firecracker setting device. Background technique [0002] It is a secular tradition of the Chinese nation to set off firecrackers when there are weddings and funerals. In the sound of crackling firecrackers, people are either happy or sad, but the traditional way of setting off firecrackers will bring many negative effects.
