Problems solved by technology

[0002] Traditional fireworks use gunpowder, which will produce a lot of smoke and harmful gases when set off, which not only pollutes the air, but also has problems such as fire and personal injury. It has been banned in some cities in our country
At present, the existing electronic fireworks on the market only solve the problems of polluting the air. The discharge process is mainly to spray out colored confetti and reflective paper and cooperate with the whistling of the whistle to produce the effect of fireworks display. The ornamental value at night is not good. High, it will reduce the feeling of setting off a lot of fireworks
Therefore, the current electronic fireworks can not solve the problem of simulating the lift-off of traditional fireworks, lack dynamics in form, and cannot replace traditional fireworks.

Embodiment 1

[0024] Such as figure 1 An electronic firework that can be launched and recovered, including a launch tube 1, an ejection device 2, a rocket bomb 3, a fastening switch 4 and a sounding device 5, the fastening switch 4 is located at the bottom of the launch tube 1, and the rocket bomb 3 is at the bottom of the launch tube 1 The bottom fastens above the switch 4, and the sounding device 5 is positioned at the side of the launch tube. In this embodiment, the elastic part of the ejection device 2 in the launch tube 1 is a rubber band 21, and one end is fixed on the top of the launch tube 1, and the other end is fixed on the arrow bomb 3. head, such as Figure 4 The fastening switch 4 is buckled in at the bottom of the arrow body 34 of the rocket bomb 3 . Open the switch 31 of the rocket bomb 3 before launching to make the LED light 33 glow; When the rocket 3 flies out of the launch tube 1, the flexible blades are automatically opened, and during the descent, the rocket 3 rotates...

Embodiment 2

[0026] This embodiment is basically the same as Embodiment 1, except that the elastic member in the ejection device 2 is a tension spring 22, such as figure 2 , in the case of the same ejection method, the stability and life of the parts are improved.

Embodiment 3

[0028] This embodiment is basically the same as Embodiment 1, except that the elastic member in the ejection device 2 is a compression spring 23, such as image 3 , the compression spring 23 is located at the bottom of the launching tube 1 and is compressed by the rocket 3 , and the bottom of the arrow body 34 of the rocket 3 is buckled into the fastening switch 4 . In the case of the same launch effect, the efficiency of reloading Dart 3 is improved.

Abstract

The invention discloses an electronic firework capable of launching and recycling. The electronic firework comprises a launching tube, an ejector device, an arrow missile, a tensioning switch and a sound generating device, wherein the tensioning switch is positioned at the bottom of the launching tube; the arrow missile is arranged at the bottom of the launching tube and above the tensioning switch; an elastic force is applied to the arrow missile at the bottom of the launching tube by the ejector device, and the arrow missile is fixed by the tensioning switch. An LED lamp is turned on beforethe arrow missile is launched, and the arrow missile moves upwards for levitation after being launched by the launching tube; the sound generating device generates sound that the firework is launchedand exploded in the launching process; flexible blades are opened automatically when the arrow missile flies out of the launching tube, and in the descending process, the arrow missile rotates and slowly falls to the ground due to the actions of gravity and air resistance. The arrow missile after falling can recycle, or serves as a toy for use independently.

Description

technical field [0001] The invention relates to an electronic firework capable of emitting and recovering. Background technique [0002] Traditional fireworks use gunpowder, which will produce a lot of smoke and harmful gases when set off, which not only pollutes the air, but also has problems such as fire and personal injury. It has been banned in some cities in our country. At present, the existing electronic fireworks on the market only solve the problems of polluting the air. The discharge process is mainly to spray out colored confetti and reflective paper and cooperate with the whistling of the whistle to produce the effect of fireworks display. The ornamental value at night is not good. Higher, there will be a lot less feeling of setting off fireworks. Therefore, the current electronic fireworks can not solve the problem of simulating the lift-off of traditional fireworks, lack dynamics in form, and cannot replace traditional fireworks.
