Cold firework spraying equipment

Abstract

The invention discloses cold firework spraying equipment. The cold firework spraying equipment comprises a discharging mechanism, a feeding heating mechanism and a jetting mechanism; the jetting mechanism is used for igniting metal powder and conveying the ignited metal powder to the feeding and heating mechanism; and the feeding and heating mechanism is used for spraying the ignited metal powderout of the cold firework spraying equipment, and a spraying pipeline in the jetting mechanism is of a bent pipeline structure. According to the cold firework spraying equipment, compared with the prior art, the problem that because rainwater or other foreign matters directly fall onto an airflow source, the airflow source is damaged is solved, and the service life of the cold firework spraying equipment can be remarkably prolonged.

Description

technical field [0001] The present application relates to the technical field of stage equipment, and more specifically, relates to a cold pyrotechnic eruption equipment. Background technique [0002] Because the existing cold pyrotechnic eruption equipment is a straight pipe, and the injection pipe does not have a drainage function, if it is used in an environment with rain or other foreign objects, the rain or other foreign objects may directly fall onto the airflow source. result in damage to the airflow source. Moreover, with the prolongation of use time, rainwater or other foreign objects will gradually accumulate in the injection pipe, affecting the injection function of the injection pipe, and some even enter the interior of the cold pyrotechnic eruption equipment, causing the internal circuit system, electrical components and other components to be short-circuited or corroded to prevent normal operation. [0003] At present, this kind of problem of cold pyrotechnic...

Problems solved by technology

[0002] Because the existing cold pyrotechnic eruption equipment is a straight pipe, and the injection pipe does not have a drainage function, if it is used in an environment with rain or other foreign objects, the rain or other foreign objects may directly fall onto the airflow source. Causes damage to the airflow source

Moreover, with the prolongation of use time, rainwater or other foreign objects will gradually accumulate in the injection pipe, affecting the injection function of the injection pipe, and some even enter the interior of the cold pyrotechnic eruption equipment, causing the internal circuit system, electrical components and other components to be short-circuited or corroded and unable to function properly

[0003] At present, this kind of problem of cold pyrotechnic eruption equipment can be solved by adding a protective cover around the cold pyrotechnic eruption equipment, but the protective performance of this type of protective cover is not high, and the protective performance depends on the environment and environment of the site to a large extent. Due to human factors, these protective covers must be removed when the machine is in use, which can only make the equipment play a protective role in the environment of rain or other foreign objects, and cannot have the function of making it ready to use in the environment of rain or other foreign objects.

[0004] Therefore, how to provide a cold pyrotechnic eruption device, which can overcome the problem of damage to the air flow source caused by rainwater or other foreign objects directly falling onto the airflow source, and realize that the cold pyrotechnic eruption device can be used for a long time in an environment with rainwater or other foreign objects , enhance durability, prolong service life, has become a technical problem to be solved urgently by those skilled in the art
