Description

Technical Field

[0001] The utility model relates to the technical field related to spray flowers, in particular to a small spray flower with a modeling shape. Background Art

[0002] Spray flower is one of the leading products in fireworks. The existing spray flower products have developed into low smoke and smokeless products, which are widely used in home, stage and indoor fireworks. The effect of fireworks is the key factor for the product to be popular in the market. When a single tube cannot achieve the ideal effect in spray flower, multiple spray flower tubes are combined together through technology to produce a multi-level combination shape to achieve the ideal design effect.

[0003] Existing shaped spray flowers are formed by dividing a plurality of different spray flower tube cavities to ignite the internal gunpowder layer, and the fireworks are sprayed upwards through the combustion of the gunpowder layer. In order to increase the duration of the spray flower, more gunpowder is often installed in the spray flower tube cavity, and the gunpowder generally burns from top to bottom. As the gunpowder layer burns, the burning point is farther and farther away from the position of the spray hole set at the top of the spray flower tube cavity, which results in a poor spray flower effect of the gunpowder burned in the lower layer. For this reason, those skilled in the art have proposed a shaped small spray flower to solve the problems raised in the above background. Utility Model Content

[0004] The purpose of the utility model is to provide a small spray flower with a shape to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A small spray flower with a decorative shape comprises a base, a main cylinder body is installed on the top of the base, a plurality of spray flower tube cavities of the same shape and size and arranged neatly are divided in the main cylinder body, a triggerable extension component is installed on the bottom of the inner cavity of the spray flower tube cavity, a movable plate is installed on the top of the triggerable extension component, a gunpowder layer is installed on the top of the movable plate, a main fuse is arranged in the base, one end of the main fuse extends to the outside of the base, and the part of the main fuse located in the base is distributed in an S-shape, an auxiliary fuse is arranged in the spray flower tube cavity, the bottom end of the auxiliary fuse is connected to the main fuse, and the top end of the auxiliary fuse is connected to the top of the gunpowder layer, the auxiliary fuse can drive the triggerable extension component to operate when burning to the middle part, and the triggerable extension component can drive the movable plate to rise slowly when operating, and a top plate is installed on the top of the main cylinder body, and a plurality of flame-spraying holes corresponding to the position and quantity of the spray flower tube cavity are arranged on the top plate.

[0007] As a further solution of the utility model: an isolating column is connected to the middle of the top end of the movable plate, the upper part of the auxiliary lead is wrapped in the isolating column, and the top end of the auxiliary lead extends out of the top end of the isolating column.

[0008] As a further solution of the utility model: the spray tube cavity is arranged in a rectangular column shape, and the outer wall of the movable plate is slidably fitted with the inner wall of the spray tube cavity.

[0009] As a further solution of the utility model: the triggerable extension assembly includes an elastic member, a connecting rope and block gunpowder, the top of the elastic member and the top of the connecting rope are both connected to the bottom end of the movable plate, the bottom end of the elastic member and the bottom end of the connecting rope are both connected to the inner bottom surface of the spray tube cavity, the elastic member is in a compressed state, the block gunpowder is installed at the bottom end of the movable plate, and the block gunpowder is simultaneously connected to the top of the connecting rope and the middle part of the auxiliary fuse.

[0010] As a further solution of the utility model: the connecting rope and the block gunpowder are both arranged on the inner periphery of the elastic member, the connecting rope is arranged as two symmetrically distributed about the elastic member, the two ends of the block gunpowder are respectively connected to the top of the two connecting ropes, and the middle part of the block gunpowder is connected with the auxiliary fuse through an interlaced fit.

[0012] The utility model has the following advantages: the spray flower adjusts the position of the movable plate by setting a triggerable extension component. When the auxiliary fuse drives the triggerable extension component to operate and ignites the gunpowder layer, the gunpowder layer burns from the top downward. During combustion, the triggerable extension component drives the movable plate to move slowly upward, so that the top burning point of the gunpowder layer always maintains a close distance to the flame injection hole, thereby ensuring the combustion effect of the entire gunpowder layer and ensuring a better spray effect of the overall spray flower.

[0020] Example 1: Please refer to Figures 1 to 3 A small spray flower with a modeling structure comprises a base 1, a main cylinder 2 is installed on the top of the base 1, and a plurality of spray flower tube chambers 3 with the same shape and size and arranged neatly are divided in the main cylinder 2, a triggerable extension component 9 is installed at the bottom of the inner cavity of the spray flower tube chamber 3, a movable plate 7 is installed on the top of the triggerable extension component 9, and a gunpowder layer 8 is installed on the top of the movable plate 7, a main fuse 4 is arranged in the base 1, one end of the main fuse 4 extends to the outside of the base 1, and the part of the main fuse 4 located in the base 1 is distributed in an S-shaped direction, and an auxiliary fuse is arranged in the spray flower tube chamber 3. Line 10, the bottom end of the auxiliary fuse 10 is connected to the main fuse 4, and the connection positions of each auxiliary fuse 10 and the main fuse 4 are different, ensuring that the auxiliary fuses 10 are ignited in sequence, the top end of the auxiliary fuse 10 is connected to the top of the gunpowder layer 8, and the gunpowder layer 8 is columnar. When the auxiliary fuse 10 burns to the middle, it can drive the trigger extension component 9 to operate, and when the trigger extension component 9 operates, it can drive the movable plate 7 to rise slowly. A top plate 5 is installed on the top of the main cylinder body 2, and a plurality of flame-spraying holes 6 corresponding to the position and quantity of the spray tube cavity 3 are arranged on the top plate 5.

[0021] See also Figure 1 , Figure 2 An isolation column 11 is connected to the middle of the top of the movable plate 7, and the upper part of the auxiliary fuse 10 is wrapped in the isolation column 11. The top of the auxiliary fuse 10 extends to the outside of the top of the isolation column 11. The isolation column 11 ensures that the auxiliary fuse 10 will not ignite the bottom of the gunpowder layer 8 first, and the top of the gunpowder layer 8 will not be ignited until the auxiliary fuse 10 burns to the top. The spray tube cavity 3 is set to a rectangular columnar shape, and the outer wall of the movable plate 7 is slidably fitted with the inner wall of the spray tube cavity 3 to ensure the movement stability of the movable plate 7.

[0022] Example 2: See Figures 2 to 4On the basis of the first embodiment, the triggerable extension assembly 9 includes an elastic member 12, a connecting rope 13 and a block of gunpowder 14, the top of the elastic member 12 and the top of the connecting rope 13 are both connected to the bottom end of the movable plate 7, the bottom end of the elastic member 12 and the bottom end of the connecting rope 13 are both connected to the inner bottom surface of the spray tube cavity 3, the elastic member 12 is in a compressed state, the block of gunpowder 14 is installed at the bottom end of the movable plate 7, and the block of gunpowder 14 is simultaneously connected to the top of the connecting rope 13 and the auxiliary The middle part of the fuse 10 is connected. In the present embodiment, the priority is selected as a spring. A damping structure is arranged on the elastic member 12 to ensure that it will not stretch rapidly but slowly when it recovers. The connecting rope 13 and the block gunpowder 14 are both arranged on the inner periphery of the elastic member 12. The connecting rope 13 is arranged as two symmetrically distributed about the elastic member 12. The two ends of the block gunpowder 14 are respectively connected to the tops of the two connecting ropes 13. The middle part of the block gunpowder 14 is connected with the auxiliary fuse 10 through-and-through.

[0023] See also Figure 2 , Figure 4 An ash collecting hole 15 is provided on the upper inner wall of the spray tube cavity 3, and a guide groove 16 is connected to the top of the ash collecting hole 15. The guide groove 16 is inclined. After the gunpowder layer 8 burns, the gunpowder ash accumulated on the top of the gunpowder layer 8 will enter the ash collecting hole 15 through the guide groove 16, thereby not affecting the combustion effect of the top of the gunpowder layer 8.

[0024] Working principle: When in use, the main fuse 4 is ignited, and the main fuse 4 ignites the auxiliary fuse 10 in turn. When the auxiliary fuse 10 burns from the bottom to the top, the block gunpowder 14 is ignited first. After the block gunpowder 14 is ignited, the top part of the connecting rope 13 is burned, so that the connecting rope 13 is no longer connected to the movable plate 7. At this time, the elastic member 12 is no longer restricted and thus achieves elastic recovery and elongation, thereby driving the movable plate 7 to move up slowly. At the same time, the auxiliary fuse 10 ignites the top of the gunpowder layer 8, and the gunpowder layer 8 starts to burn from top to bottom. When the gunpowder layer 8 burns, fireworks are ejected outward through the flame-spraying hole 6. Through the upward movement of the movable plate 7, the position of the burning point at the top of the gunpowder layer 8 is always close to the flame-spraying hole 6, thereby ensuring the combustion effect of the entire gunpowder layer 8.
