Combined firework capable of displaying projected image

Abstract

The invention discloses a combined firework capable of displaying projected images. It includes a smoke effect tube combination, a fireworks effect tube combination, an image projection device and a nozzle device. In the middle of the rear part of the assembly, the image projection device includes a box body, a reflector, a condenser, a slide picture, a bracket, a projection lens, a projection tube, a luminous body, a U-shaped notch, a smoke exhaust window, a picture insertion port, and the inner cavity of the box The above-mentioned components are installed in sequence, wherein the condenser, the slide picture, and the projection lens are arranged in the projection tube, and a smoke exhaust window and a picture insertion port are also provided on the top surface of the box body, and a U-shaped notch is provided in the middle of the projection tube, and the luminous body The luminescent medicine core and the medicine core fuse are constructed in cooperation, and the image projection device can also be assembled by sliding and cooperating with the sliding rod through the conduit. The invention has the advantages of simple structure, 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 since ancient times, the most direct expression of wishes is the image. Or text. Although the combined fireworks in the fireworks display are the main varieties commonly used in festive festivals, the current combined fireworks display only shows the changes in the patterns of sound, light, and color, sometimes accompanied by simple English letters, but they cannot be displayed during the display. The image is displayed, and the effect is still relatively single, and further improvement and innovation are needed to make the firework display effect closer to people's real life, and to bet...

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
