Abstract
The utility model provides a fireworks launching device, comprising a launching cylinder, a large air storage cylinder, and a small air storage cylinder. The bottom of the large air storage cylinder is provided with the small air storage cylinder which is disposed under the launching cylinder; the center of a top cover of the large air storage cylinder is provided with a circular hole; the launching cylinder is inserted in the large air storage cylinder through the circular hole; and a cylinder body of the small air storage cylinder is provided with a one-way valve and the bottom of the small air storage cylinder is provided with an inlet valve and an exhaust valve. The fireworks launching device has the advantages of simple structure, reusability and high instantaneous air displacement.
Description
Technical field:
The utility model relates to a kind of celebration articles for use, particularly a kind of fireworks display emitter.
Background technology:
The emission of paper-cut fireworks display at present is to adopt rubber stopper seal; With manual draw bar the gland on air storage chamber top is opened; The rubber stopper that the impulse force of dependence air storage chamber moment discharging is provided with air storage chamber top cover center backs down and accomplishes emission, and this structure one is that rubber stopper seal property is bad, is difficult to guarantee to seal; The 2nd, owing to use rubber stopper seal; The size of steam vent is 1/10th of a launching tube diameter, and our bottleneck effect of saying that Here it is causes air storage chamber gas to spray moment; Thereby fireworks display firing altitude and scope are also less, are difficult to satisfy the requirement of large-scale celebration activity; The 3rd, the transmitter of this structure mostly is a disposable product, and environment is impacted and waste resource.Therefore, be necessary to improve.
The utility model content:
The goal of the invention of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, the reusable and big fireworks display emitter of moment capacity.
For realizing the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of fireworks display emitter; Comprise launching tube, big gas receiver and little gas receiver, big gas receiver bottom is provided with little gas receiver, and this little gas receiver is located at the launching tube bottom; Said big gas receiver top cover center is provided with circular hole; Said launching tube inserts in the said big gas receiver through this circular hole, and the stack shell of said little gas receiver is provided with check valve, and the bottom is provided with intake valve and air bleeding valve.
The circular hole size at said big gas receiver top cover center is complementary with the external diameter of launching tube, and launching tube outer wall and this circular hole fixing seal.
The stack shell thickness of said big gas receiver is slightly larger than the stack shell thickness of said little gas receiver.
The utility model has following advantage with respect to prior art:
The utility model is simple in structure, and is easy to operate, and the air storage chamber compressive resistance is high, good seal performance; Gas-storing capacity is big, and the impulse force that moment discharges is big, makes the height and the scope of fireworks display emission strengthen greatly; Can satisfy the requirement of large-scale celebration activity, and reusable, economize on resources.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of the utility model.
The specific embodiment:
Referring to Fig. 1 and Fig. 2,, comprise launching tube 1, big gas receiver 2 and little gas receiver 3 according to a kind of fireworks display emitter that the utility model provides; Big gas receiver 2 bottoms are provided with little gas receiver 3; And this little gas receiver 3 is located at launching tube 1 bottom, and big gas receiver 2 top cover centers are provided with circular hole, and launching tube 1 inserts in the big gas receiver 2 through this circular hole; The stack shell of little gas receiver 3 is provided with check valve 4, and the bottom is provided with intake valve 5 and air bleeding valve 6.
The circular hole size at big gas receiver 2 top cover centers is complementary with the external diameter of launching tube 1, and launching tube 1 outer wall and this circular hole fixing seal.The stack shell thickness of big gas receiver 2 is slightly larger than the stack shell thickness of little gas receiver 3.
The foregoing description only supplies to explain the usefulness of the utility model; And be not the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each claim.
