Description

Technical Field

[0001] This utility model relates to the technical field of firecracker setting equipment, specifically to a safe and continuous setting device for double-bang firecrackers. Background Technology

[0002] This section introduces background technology that may be related to various aspects of the embodiments of this utility model, which is believed to provide useful background information to help readers better understand the various aspects of the embodiments of this utility model. Therefore, it is understood that the description in this section is for the above purposes and does not constitute an admission of the prior art.

[0003] During festivals and celebrations, people often use fireworks and firecrackers as a way to celebrate. Double-bang firecrackers, also known as "two-bang firecrackers," are a type of firecracker that explodes once on the ground and then rises into the air to explode again, symbolizing the hope for rising higher and higher. As a traditional folk item, double-bang firecrackers are commonly used in festivals, weddings, and memorial services. Because they rely on the recoil force generated by the explosion of gunpowder at the bottom to propel them into the air, they pose a certain degree of danger when used. The paper tube of a double-bang firecracker contains two layers of gunpowder. The lower part of the cylindrical tube contains propellant gunpowder, and the upper part contains explosive gunpowder. A fuse connects the propellant gunpowder to the fuse, which ignites the propellant gunpowder first. The propellant gunpowder explodes downwards, generating propulsion that lifts the cylindrical tube into the air before the explosive gunpowder detonates, creating a loud bang in mid-air.

[0004] Two-bang firecrackers are individual firecrackers and must be lit one by one. Before lighting, the firecracker must be placed upright on the ground. A flat location must be selected for lighting them. In this process, finding a suitable location wastes a lot of time. The traditional way of lighting two-bang firecrackers is to light them one by one. Each time a two-bang firecracker is lit, the person lighting it must get close and light it again. Lighting it multiple times inevitably poses a risk of injury or burns.

[0005] Existing firecracker triggers consist of multiple interconnected small sleeves, with each firecracker inserted into the inner side of one sleeve. When ignited, only the fuse of the outermost firecracker needs to be lit. The flame from the first firecracker ignites the fuses of adjacent firecrackers, thus achieving the goal of igniting multiple firecrackers with a single ignition, supposedly reducing danger. However, when using existing firecracker triggers, the fuses of multiple firecrackers are simultaneously ignited by the flame of the first firecracker, resulting in excessively rapid ignition and near-simultaneous explosions. The multiple firecrackers only provide a short period of enjoyment. Utility Model Content

[0006] The problem to be solved by this utility model embodiment is how to provide a safe and continuous firing device for double-bang firecrackers and a fish waste separator.

[0007] To address the shortcomings of existing technologies, this utility model provides a safe and continuous firing device for double-bang firecrackers, which can effectively prevent water from seeping into the motor and damaging it.

[0008] In a first aspect, this utility model provides a safe and continuous firing device for double-bang firecrackers, comprising:

[0009] A base, on which a support is provided;

[0010] The support is equipped with a firing barrel, which has openings at the top and bottom.

[0011] The base is provided with a chassis, and the chassis is movably connected to the base via a rotating shaft;

[0012] The chassis is provided with a plurality of guide tubes for holding double-bang firecrackers. The side walls of the plurality of guide tubes are connected end to end to form a ring. The plurality of guide tubes are interconnected so that the fuses of adjacent double-bang firecrackers explode and ignite each other.

[0013] A guide plate is provided at the bottom of the guide tube so that when the double-bang firecracker is fired, it drives the chassis to rotate, causing the adjacent guide tube to align with the bottom of the firing barrel.

[0014] In some other embodiments of the double-bang firecracker safety continuous firing device described in this specification, the rotating shaft is provided with a one-way anti-reverse component, and the chassis is driven to rotate in one direction when the double-bang firecracker is fired.

[0015] In some other embodiments of the double-bang firecracker safety continuous firing device described in this specification, the height of the guide tube is lower than the height of the double-bang firecracker.

[0016] In some other embodiments of the double-bang firecracker safety continuous firing device described in this specification, there is a gap between the top of the guide tube and the bottom inlet of the firing tube for the double-bang firecracker to pass through when the chassis rotates.

[0017] In some other embodiments of the double-bang firecracker safety continuous firing device described in this specification, a limiting device is also included to limit the angle of rotation of the chassis and to align the guide tube with the bottom of the firing barrel.

[0018] In some other embodiments of the double-bang firecracker safety continuous firing device described in this specification, the limiting device is fixed to the bracket or the firing barrel.

[0019] In some other embodiments of the double-bang firecracker safety continuous firing device described in this specification, the position of the limiting device corresponds to the position of the gap.

[0020] In some other embodiments of the double-bang firecracker safety continuous firing device described in this specification, a limiting roller is provided at the position of the limiting device, and a groove is provided on the roller. The bottom of the groove is aligned with the inner wall of the firing barrel, and the inner diameter of the groove is approximately equal to the inner diameter of the firing barrel.

[0021] In some other embodiments of the double-bang firecracker safety continuous firing device described in this specification, a deflagration chamber is provided between adjacent guide tubes, and the deflagration chamber is connected to the adjacent guide tubes so that the tail flame after the double-bang firecracker is fired ignites the fuse of the double-bang firecracker in the adjacent guide tube.

[0022] In some other embodiments of the double-bang firecracker safety continuous firing device described in this specification, there is a sufficient firing gap between the outer wall of the double-bang firecracker and the inner wall of the guide tube. The firing gap is sufficient to allow the tail flame of the double-bang firecracker to pass through the firing gap and ignite the fuse of the adjacent double-bang firecracker in the guide tube.

[0023] As can be seen from the above technical solution, the double-bang firecracker safety continuous firing device provided by this utility model embodiment uses multiple guide tubes set on the chassis to hold the double-bang firecrackers. The side walls of the multiple guide tubes are connected end to end to form a ring, and the multiple guide tubes are interconnected so that the fuse parts of adjacent double-bang firecrackers explode and ignite each other. When the double-bang firecracker is fired, the chassis is driven to rotate, causing the adjacent guide tubes to align with the bottom of the firing barrel. The flame generated by the downward explosion of the propellant also ignites the fuse parts in the adjacent guide tubes, and so on, one after another, they are continuously fired.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] like Figures 1 to 4As shown in the figure, an embodiment of the present invention provides a safe and continuous firing device for double-bang firecrackers, comprising: a base 1, on which a support 13 is provided; a firing tube 11 is provided on the support 13, the top and bottom of the firing tube 1 being open; a chassis 10 is provided on the base 1, the chassis 10 being movably connected to the base 1 via a rotating shaft 101; a plurality of guide tubes 12 for placing double-bang firecrackers 2 are provided on the chassis 10, the side walls of the plurality of guide tubes 12 being connected end to end to form a ring, the plurality of guide tubes 12 being interconnected, so that the fuse parts 21 of adjacent double-bang firecrackers 2 ignite together; a guide plate 19 is provided at the bottom of the guide tube 12, so that when the double-bang firecracker 2 is fired, it drives the chassis 10 to rotate, causing adjacent guide tubes 12 to align with the bottom of the firing tube 11. The following is a detailed description of the safe and continuous firing device for double-bang firecrackers provided in this embodiment of the present invention.

[0037] like Figures 1 to 4 As shown in this embodiment of the invention, when the double-bang firecracker 2 is fired, the propellant at the bottom of the firecracker explodes downwards, generating a propulsive force that lifts the cylindrical body into the air. Simultaneously, the propulsive force from the downward explosion of the propellant pushes the guide plate 19 located at the bottom of the guide tube 12. Under the push of the reaction force, the double-bang firecracker 2 drives the chassis 10 to rotate, causing the adjacent guide tubes 12 to align with the bottom of the firing barrel 11. At the same time, the flame generated by the downward explosion of the propellant also ignites the fuse section 21 inside the adjacent guide tubes 12, thus continuously igniting them one after another.

[0038] In this embodiment of the invention, the rotating shaft 101 is equipped with a one-way anti-reverse component (not shown in the figure), which drives the chassis 10 to rotate in one direction when the double-bang firecracker 2 is fired. This can prevent improper operation from causing the chassis 10 to rotate in the opposite direction. The one-way anti-reverse component can be implemented using existing, relatively mature solutions, which will not be described in detail here.

[0039] like Figures 4 to 5As shown in this embodiment of the invention, the height of the guide tube 12 is lower than the height of the double-bang firecracker 2. A gap exists between the top of the guide tube 12 and the bottom inlet of the firing barrel 11, allowing the double-bang firecracker 2 to pass through when the chassis 10 rotates. The portion of the double-bang firecracker 2 extending above the guide tube 12 smoothly passes through the gap when the chassis 10 rotates. The safe continuous firing device for double-bang firecrackers provided in this embodiment of the invention also includes a limiting device 121 for limiting the rotation angle of the chassis 10 and aligning the guide tube 12 with the bottom of the firing barrel 11. The limiting device 121 is fixed to the bracket 13 or the firing barrel 11. The position of the limiting device 121 corresponds to the position of the gap. This prevents the chassis 10 from rotating too much when the double-bang firecracker 2 is fired, and prevents adjacent guide tubes 12 from missing the bottom of the firing barrel 11.

[0040] like Figures 4 to 6 As shown in this embodiment of the invention, to prevent energy loss due to friction between the limiting device and the propellant at the bottom of the double-bang firecracker during the downward explosion of the propellant that lifts the cylindrical body, the limiting device 121 is equipped with a limiting roller 122. The roller has a groove 123, the bottom of which is aligned with the inner wall of the firing barrel 11, and the inner diameter of the groove 123 is approximately equal to the inner diameter of the firing barrel 11. During the downward explosion of the propellant at the bottom of the double-bang firecracker to lift the cylindrical body, the limiting roller 122 rotates as the firecracker rises.

[0041] like Figures 7 to 8B As shown in this embodiment of the invention, in order to effectively ensure that the flame generated by the downward explosion of the gunpowder of the double-bang firecracker 2 also ignites the fuse part 21 in the adjacent guide tube 12, an explosion chamber 23 is provided between the adjacent guide tubes. The explosion chamber 23 is connected to the adjacent guide tube 12. The fuse part 21 of the double-bang firecracker 2 in the adjacent guide tube 12 extends into the explosion chamber 23, so that the tail flame of the double-bang firecracker 2 after being lit ignites the fuse part of the double-bang firecracker 2 in the adjacent guide tube 12. This process is repeated one by one until all the double-bang firecrackers 2 in the guide tubes 12 on the chassis 10 have been lit.

[0042] like Figures 9 to 10BAs shown, in another embodiment of this utility model, in order to effectively ensure that the flame generated by the downward explosion of the propellant of the double-bang firecracker 2 also ignites the fuse section 21 in the adjacent guide tube 12, there is a sufficient firing gap 20 between the outer wall of the double-bang firecracker 2 and the inner wall of the guide tube 12. The firing gap 20 is sufficient to allow the tail flame of the double-bang firecracker after firing to pass through the firing gap 20 and ignite the fuse section 21 of the double-bang firecracker 2 in the adjacent guide tube 12. This embodiment can achieve the effect of the flame generated by the downward explosion of the propellant of the double-bang firecracker 2 igniting the fuse section 21 in the adjacent guide tube 12 without the need for a combustion chamber.

[0043] In summary, the double-bang firecracker safety continuous firing device provided by this utility model embodiment uses multiple guide tubes on the chassis to hold the double-bang firecrackers. The side walls of the multiple guide tubes are connected end to end to form a ring, and the multiple guide tubes are interconnected so that the fuse parts of adjacent double-bang firecrackers explode and ignite each other. When the double-bang firecracker is fired, it drives the chassis to rotate, causing the adjacent guide tubes to align with the bottom of the firing barrel. The flame generated by the downward explosion of the propellant also ignites the fuse parts in the adjacent guide tubes, and so on, continuously firing one after another.
