Combined firework capable of displaying projected image

Abstract

The invention discloses a combined firework capable of displaying a projected image. The combined firework comprises a smoke effect barrel combination, a firework effect barrel combination, an image projector and a smoke ejecting nozzle device. The smoke effect barrel combination is arranged at the front end of a combined firework body. The firework effect barrel combination is arranged several rows behind the smoke effect barrel combination. The image projector is arranged in the middle position in the rear part of the combined firework body and comprises a box body, a reflective mirror, a collecting mirror, a magic lamp picture, a bracket, a projecting lens, a projecting tube, a light emitter, a U-shaped slot, a smoke exhaust window and a picture inserting opening. The above parts are installed in the box body orderly. The collecting lens, the magic lamp picture and the projecting lens are arranged in the projecting tube. The smoke exhaust window and the picture inserting opening are further arranged on the top end surface of the box body. The U-shaped slot is arranged in the middle of the projecting tube. The light emitter is formed by a light emitting core and a core conductive lead. The image projector can be further assembled and matched with a sliding rod in a sliding manner. The combined firework has the advantages of simple structure and easy implementation and the like.

Description

technical field [0001] The invention relates to a firework manufacturing technology, in particular to a combined firework capable of displaying projected images. Background technique [0002] Setting off fireworks is a way for people to express good wishes and entertainment on festive days. Because the atmosphere of fireworks is strong and dazzling, it can express people's joyful atmosphere, but the most direct expression of wishes from ancient times to the present is images. or text. Although the combination fireworks in the fireworks display are the main varieties commonly used by people to celebrate festivals, the current combination fireworks display only shows the changes in the patterns of sound, light and color. Sometimes, although there are simple English letters appearing, they cannot Showing the image picture, the effect is still relatively simple, and needs to be further improved and innovated, so that the fireworks display effect is closer to people's real life,...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem of singleness of the existing combined fireworks display, which only has the singleness of pattern, color, sound, and light in combination with the injection effect, and comprehensively adopt the existing fireworks manufacturing technology, fireworks display technology, pyrotechnic powder lighting technology, projection imaging technology, etc. Technology, through technological innovation and integration, a combined firework that can display projected images is proposed. The combined firework has a simple structure, is easy to use, and has good real-time compatibility. The light source provided by the body projects the image onto the unfolded smoke screen, and cooperates with a variety of sound, light, and color fireworks effects, so that the wishes expressed through the discharge include three-dimensional effects of sound, light, color, and images, which can solve the problem Existing combination fireworks display only have sound, light, and color spray effects, but cannot display projected images, etc., so as to realize a combined firework device integrating smoke spray, spray flowers, screams, and image images, and achieve the goal of low cost
