Description

Technical Field

[0001] The utility model relates to the technical field of fireworks display, in particular to a protective cover for horn-shaped fireworks display. Background Art

[0002] Fireworks, also known as flower bombs, fireworks, pyrotechnics, and firecrackers, are defined in the "China Fireworks and Firecrackers Standards - Safety and Quality" as entertainment products using pyrotechnic compositions to produce sound, light, and color. Invented by the Chinese working people at the earliest, they are often used in grand ceremonies or performances; when some fireworks are being set off, protective covers are used for safety. However, when horn-shaped fireworks are being set off, the horn-shaped fireworks will collide with the inside of the protective cover, affecting the formation of the horn-shaped fireworks. Therefore, a protective cover for horn-shaped fireworks display is proposed. Summary of the Utility Model

[0003] To solve the above at least one technical drawback, the utility model provides a protective cover for horn-shaped fireworks display, which includes a transparent cover. The transparent cover is arranged in a bulb shape, and a plurality of exhaust holes are evenly arranged in the hemispherical area of the transparent cover.

[0004] Furthermore, an air intake base is sleeved at the bottom of the transparent cover.

[0005] Furthermore, the air intake base includes a support ring and a socket ring arranged in upper and lower layers. The connection between the top of the support ring and the bottom of the socket ring forms an arc-shaped groove located outside the socket ring. The transparent cover is sleeved on the socket ring. A plurality of air intake holes are evenly arranged on the outer wall of the support ring, and a gap is formed at the bottom end of the socket ring.

[0006] Furthermore, an arc-shaped ring plate is provided at the inner edge of the bottom end of the socket ring.

[0007] Furthermore, the transparent cover is made of acrylic material. Advantageous Effects

[0008] The transparent cover is arranged in a bulb shape, enabling the transparent cover to better fit the horn-shaped fireworks display. When the horn-shaped fireworks are being set off, the horn-shaped fireworks presented can just fit the bulb-shaped transparent cover, so that the inner wall of the transparent cover will not affect the blooming of the horn-shaped fireworks. And by evenly arranging a plurality of exhaust holes in the hemispherical area, the smoke can be discharged smoothly while being completely protected by the transparent cover.

[0009] The air intake base includes a support ring and a socket ring arranged in upper and lower layers. The connection between the top of the support ring and the bottom of the socket ring forms an arc-shaped groove located outside the socket ring. The transparent cover is sleeved on the socket ring. A plurality of air intake holes are evenly arranged on the outer wall of the support ring, and a gap is formed at the bottom end of the socket ring.

[0010] When setting off fireworks, the air inside the transparent cover is heated and expands. Through the setting of the arc-shaped ring plate, the air will expand upward as much as possible, forming an air flow from bottom to top inside the transparent cover, enabling the air inlet holes to better enter the oxygen-containing air. The function of the arc-shaped ring plate is to prevent the air inside the transparent cover from flowing downward.

[0011] The realization, functional features, and advantages of the present utility model will be further described in conjunction with embodiments with reference to the accompanying drawings. Description of the Drawings

[0012] Figure 1 It is an isometric view of the whole of the present utility model.

[0013] Figure 2 It is an isometric view of the air inlet base of the present utility model.

[0014] In Figures 1 to 2 , the corresponding relationship between the component names or lines and the drawing reference numerals is: transparent cover 1, smoke exhaust hole 101, air inlet base 2, support ring 201, air inlet hole 211, socket ring 202, arc-shaped ring plate 221, arc-shaped groove 203. Detailed Embodiment

[0015] Please refer to Figures 1 to 2 ;

[0016] This embodiment provides a protective cover for setting off horn-shaped fireworks. Referring to Figure 1 , it includes a transparent cover 1. The transparent cover 1 is arranged in a bulb shape, and a plurality of smoke exhaust holes 101 are evenly opened in the hemispherical area of the transparent cover 1;

[0017] In specific implementation, the transparent cover 1 is arranged in a bulb shape, enabling the transparent cover 1 to better fit the horn-shaped fireworks during setting off. When the horn-shaped fireworks are set off, the horn-shaped fireworks presented can just fit the bulb-shaped transparent cover 1, so that the inner wall of the transparent cover 1 will not affect the blooming of the horn-shaped fireworks. And by evenly opening a plurality of smoke exhaust holes 101 in the hemispherical area, the smoke can be discharged smoothly while being completely protected by the transparent cover 1;

[0018] Since both the horn-shaped fireworks and the bulb-shaped transparent cover 1 during setting off have a structure that is larger at the top and smaller at the bottom, the horn-shaped fireworks can fully bloom inside the bulb-shaped transparent cover 1.

[0019] Further, referring to Figure 1 , an air inlet base 2 is sleeved at the bottom of the transparent cover 1;

[0020] In specific implementation, through the setting of the air inlet base 2, oxygen can better enter the inside of the transparent cover 1, enabling the fireworks to be set off smoothly.

[0021] Further, referring toFigure 2 The intake base 2 includes a support ring 201 and a socket ring 202 that are arranged in upper and lower layers. An arc-shaped groove 203 located outside the socket ring 202 is formed at the connection between the top of the support ring 201 and the bottom of the socket ring 202. The transparent cover 1 is sleeved on the socket ring 202. A plurality of intake holes 211 are evenly formed on the outer wall of the support ring 201, and a gap is formed at the bottom end of the socket ring 202;

[0022] During specific implementation, when intake air, the air containing flue gas enters the bottom gap of the socket ring 202 from the intake holes 211 and enters the interior for combustion.

[0023] When installing the transparent cover 1, the bottom of the transparent cover 1 is sleeved on the periphery of the socket ring 202, and the bottom of the transparent cover 1 is supported inside the arc-shaped groove 203 to complete the installation of the transparent cover 1.

[0024] Furthermore, an arc-shaped ring plate 221 is provided at the inner edge of the bottom end of the socket ring 202;

[0025] During specific implementation, when setting off fireworks, the air inside the transparent cover 1 expands due to heat. Through the setting of the arc-shaped ring plate 221, the air will expand upward as much as possible, forming an upward airflow from bottom to top inside the transparent cover 1, enabling the intake holes 211 to better intake oxygen-containing air. The function of the arc-shaped ring plate 221 is to prevent the air inside the transparent cover 1 from flowing downward.

[0026] Furthermore, the transparent cover 1 is made of acrylic material;

[0027] The acrylic material has the characteristics of transparency, low price, anti-drop, and non-flammability.
