Description

Technical Field

[0001] This invention relates to the field of safety and environmental protection, and in particular to a safety device for setting off firecrackers. Background Technology

[0002] Setting off firecrackers is a traditional Chinese custom to enhance the festive atmosphere during holidays. However, injuries caused by firecrackers are common during the Spring Festival every year. Furthermore, the debris from firecrackers flies everywhere, especially in the stairwells of new residential buildings, where it can obstruct pedestrian safety and cause significant inconvenience if not cleaned up promptly. Furthermore, sparking debris can ignite flammable materials and cause fires. To prevent these safety hazards, many cities have banned firecrackers altogether, which greatly diminishes the festive atmosphere. Chinese Patent No. CN201020188076.9 discloses a firecracker igniter, comprising a base, a support column, a retaining ring, and a firing tube. The retaining ring is fixedly connected to the base, and the support column and the firecracker tube are disposed inside the retaining ring. The support column is a cylindrical structure, and its lower part is fixedly connected to the retaining ring. Multiple firecracker tubes are fixedly connected in pairs and arranged along the circumference inside the retaining ring, with the firecracker tubes adjacent to the support columns being fixedly connected to the support columns. The bottom of the firing tube is fixedly connected to the upper part of each firecracker tube, and a protective cover integrated with the firing port of the firing tube is provided. When setting off firecrackers, a lit fuse is thrown into the firing tube. Since the bottom circle of the firing tube is connected to the upper edge of each firecracker tube, the fuses of the firecrackers stuck in each firecracker tube are ignited by the fuses, resulting in a series of instantaneous explosions. It is not only safe to operate and simple in structure, but also produces a crisp sound that enhances the festive atmosphere, making it especially suitable for use in festivals, weddings, and other large-scale celebrations.

[0003] Currently, there is no truly effective firecracker protection device, although many patented concepts exist (such as patent number CN201020188076.9). Some use a mesh protective barrel shape, but with mesh protection, fine firecracker powder always flies out. While using iron plates to form a barrel shape and a baffle ring structure can generally block firecracker debris and powder, as disclosed in patent number CN201020188076.9, the sound is distorted. This invention can block firecracker debris and powder without distorting the sound of the firecrackers. Summary of the Invention

[0004] In view of the common phenomena and problems existing, the purpose of this invention is to provide a safe and environmentally friendly firework protection device that collects the debris and ash powder generated by firework in the cage-like firework chamber of the protection device, without distorting the sound of the firework.

[0005] To achieve the above effects, the present invention is implemented through the following techniques: A series of firecracker safety boxes includes a first profile protective barrier, a top cover, a chassis, a firecracker firing chamber, and profile mounting bases. The first profile protective barrier is formed by several first profiles enclosing a barrel-shaped body. The box is characterized by further including a second profile protective barrier, which is also formed by several second profiles enclosing a barrel-shaped body. The distance between two adjacent first profiles in the first profile protective barrier constitutes a first sound outlet. The second profile protective barrier is fitted around the outer ring of the first profile protective barrier, and the second profiles of the second profile protective barrier are staggered from the first profiles of the first profile protective barrier. The distance between the second profile and an adjacent first profile constitutes a second sound outlet. Each first sound outlet is formed by... The second profile blocks the firecracker debris from the first profile protective barrier, preventing it from flowing out in a straight line through the gap between adjacent second profiles. Instead, the debris is blocked by the opposing second profile (i.e., the second and first profiles are staggered circumferentially, so that the front of each first sound outlet is blocked by the corresponding second profile, forming a non-linear sound channel). Both the first and second profiles are fixed to the profile mounting base, and the first and second profile protective barriers each form an independent protective barrier, with at least two layers. The cavity formed by the first and second profile protective barriers, together with the top cover and the chassis, is the firecracker firing chamber.

[0006] Furthermore, the first profile used in the first-layer protective retaining wall has its opening or open edge facing outwards; the second profile used in the second-layer protective retaining wall has its opening or open edge facing inwards.

[0007] This invention can also be implemented using the following techniques: A series of firecracker safety firing box includes a first profile protective barrier, a top cover, a chassis, a firecracker firing chamber, and a profile mounting base. The first profile protective barrier is a barrel-shaped body formed by several first profiles. Its characteristic is that: It also includes a second profile protective barrier, which is formed by several second profiles to form a barrel shape, and both the first and second profiles are groove-shaped profiles (i.e., U-shaped profiles). The grooved profiles used in the first layer of protective retaining wall have their openings or open edges facing outwards; the grooved profiles used in the second layer of protective retaining wall have their openings or open edges facing inwards; the openings of the first and second profiles are staggered and opposite to each other; and there is a certain distance between two adjacent second profiles. The opening or empty edge of each first profile is set towards the opening or empty edge of the two adjacent second profiles, and the opening of the first profile covers a certain gap between the two adjacent second profiles, and at the same time covers the partial openings on both sides of the certain gap between the two adjacent second profiles, so that a gap is formed between the first profile and the corresponding second profile, and this gap is the second sound outlet. In the first layer of profile protective retaining wall, the distance between two adjacent first profiles is the first sound inlet; The first protective barrier is located in the inner ring, and the second protective barrier is located in the outer ring. Both the first and second protective barriers are fixed on the mounting base, and each barrier is an independent protective structure. The overall protective barrier consists of two rings of protective barriers forming a protective barrel. Because the openings of the first and second protective barriers are staggered, the firecracker debris exiting the first protective barrier cannot escape in a straight line through the gaps formed between adjacent second protective barriers. Instead, it is blocked by the opposing second protective barriers. However, the sound can be redirected and transmitted through the gaps between adjacent second protective barriers.

[0008] The cavity formed by the first profile protective barrier, the second profile protective barrier, the top cover, and the chassis is the firecracker firing chamber.

[0009] Furthermore, a mesh protective cylinder is provided on the inner ring of the first profile protective barrier, forming a firecracker firing chamber with the top cover and the base; the mesh size of the mesh protective cylinder is adapted to intercept firecracker debris of slightly larger volume, so that such debris is blocked in the inner cavity of the mesh protective cylinder; nitrate powder with a particle size smaller than the mesh size can pass through the mesh of the mesh protective cylinder and be intercepted in the gap between the first profile protective barrier and the second profile protective barrier.

[0010] Furthermore, the profile mounting base can be configured as an upper profile mounting base and a lower profile mounting base; or it can be configured as a single upper profile mounting base or a single lower profile mounting base.

[0011] Furthermore, the chassis has an integrally formed edging, and the outer perimeter of the chassis is slightly larger than the profile mounting base. The distance between the outer perimeter of the chassis and the profile mounting base is the bottom sound vent (usually not greater than the distance between the profile mounting base and the chassis). There is a gap between the profile mounting base and the upper surface of the chassis, which constitutes the bottom sound vent. The bottom surface of the mesh protective cylinder is higher than the top surface of the chassis, creating a gap between the bottom surface of the mesh protective cylinder and the top surface of the chassis.

[0012] Furthermore, the profile shapes of the first and second profile protective barriers are L-shaped, arc-shaped, arc-shaped with two folded edges, trapezoidal tubes, or grooved profiles.

[0013] Furthermore, ignition ports for setting off firecrackers are provided on the chassis, top cover, or protective retaining wall.

[0014] Furthermore, a series of firecracker placement mechanisms are provided in the firecracker firing chamber; the firecracker placement mechanism is a wave-shaped structure, a spiral surface structure, a hanging structure, or a flat structure, that is, the shape of the firecracker placement mechanism is wave-shaped, spiral surface-shaped, hanging, or flat.

[0015] Furthermore, the top cover is designed with a mesh pattern.

[0016] Furthermore, the width of the first sound outlet is smaller than the width of the profile opening of the second profile protective barrier, wherein the width of the profile opening is the distance between the two sides of the profile opening of the second profile protective barrier, and the width of the second sound outlet is smaller than the width of the first sound outlet.

[0017] Furthermore, the barrel-shaped body formed by the first profile of the first profile protective barrier and the barrel-shaped body formed by the second profile of the second profile protective barrier have a cross-section that is circular, elliptical, rectangular, or square.

[0018] Specifically, a series-type firecracker safety setting box consists of a first profile protective barrier, a second profile protective barrier, a first sound inlet, a second sound inlet, a top cover, a chassis, a firecracker setting chamber, a firecracker ignition port, and a mounting base. Its characteristic is that the spacing between the profiles of the first profile protective barrier and the profiles of adjacent first profile protective barriers forms the first sound inlet, and the second profile protective barrier is located around the outer ring of the first profile protective barrier. Between the upper and lower mounting bases of the profile installation, at least two rings of protective barriers are installed, each consisting of several profiles (which can be L-shaped, arc-shaped, arc-shaped with folded ends, or trapezoidal; materials can be stainless steel, aluminum, iron, plastic, etc.; if used for a Mauser pistol, even paper profiles can be used; hereinafter referred to as profiles for convenience). The inner ring is the first protective barrier, and the outer ring is the second protective barrier. There is a gap between the two profiles of the first protective barrier, forming the first sound outlet. The profiles of the second protective barrier are staggered with those of the first, and there is a gap between the profiles of the second and first protective barriers, forming the second sound outlet. This ensures an open sound environment (allowing for redirection). The space, for firecracker debris and ash powder, is enclosed by the profile, keeping the fine ash powder within the protective wall. This ensures that the firecracker debris and ash powder fall onto the chassis. The profile protective wall is an erected protective wall between the upper and lower profile mounting bases, with at least two rings. Sound vents are provided between the two profiles, meaning sound vents are located on all sides of each profile. The first and second profile protective walls, the top cover, and the chassis form a firecracker firing chamber. The firing chamber contains a series of firecracker placement mechanisms. The top of the protective wall enclosed by the profiles has a mesh top cover; ignition ports for the firecrackers are located around the top cover, the protective wall, or the chassis. The open edges of the first and second profiles face the inner ring of the protective wall.

[0019] The profile used in the string-shaped firecracker safety firing box can be L-shaped, arc-shaped, arc-shaped with two folded edges, trapezoidal tube, or grooved profile.

[0020] To provide an extra layer of protection, a mesh protective cylinder is installed inside the first profile protective barrier. This way, the firecracker firing chamber is located inside the mesh protective cylinder. The mesh protective cylinder keeps larger firecracker debris inside the firing chamber. However, finer powder particles, such as gunpowder dust, can still escape. It would be impossible to block the gunpowder dust with just a mesh, so a protective wall made of profiles is used to keep the firecracker debris and gunpowder dust inside the firing chamber.

[0021] Advantages of this invention: This invention maintains the consistent sound of firecrackers while preventing debris and ash from flying out. It ensures the sound of the firecrackers is smoothly redirected and that debris, ash, and sparks are intercepted at multiple levels, effectively preventing firecracker residue from splashing, dust pollution, and sparks from flying, making it safer and more environmentally friendly. We have already conducted test samples of both technical examples of this invention, and the results are very satisfactory.

[0022] The innovative aspects of this invention: Two protective barriers are erected using profiles. The profiles of the second protective barrier are staggered with those of the first protective barrier to form a protective barrier against debris and ash powder. The gaps between the two vertical profiles in all directions serve as sound passages. At the same time, a bottom sound passage is provided between the profile mounting base and the chassis. Since the chassis is slightly larger than the base, the sound can also be transmitted through the space between the base and the chassis, making the sound more realistic. Firework debris and ash powder are trapped inside the firework firing chamber and the chassis. Attached Figure Description

Detailed Implementation

[0053] The present invention will now be described in detail with reference to the accompanying drawings and examples: Example 1: This invention discloses a series-shaped firecracker safety box. The number of sections can be arbitrary, as long as they can form a barrel shape. Generally, one ring consists of 6-20 profiles (larger sections can be used for large events such as restaurants and weddings, depending on the size of the profiles). In this embodiment, one ring consists of 10 profiles. The series-shaped firecracker safety box comprises a first profile protective barrier 1, a first profile 1-1, a second profile protective barrier 2, a second profile 2-1, a first sound inlet 6, a second sound inlet 7, a top cover 5, a base 9, a firecracker firing chamber 11, a firecracker ignition port, and profile mounting bases. The key feature is that the distance between the first profile 1-1 of the first profile protective barrier 1 and the first profile 1-1 of the adjacent first profile protective barrier is the first sound inlet 6. The second profile protective barrier 2 is located on the outer ring of the first profile protective barrier 1 (see...). Figure 8At least two rings are installed on the profile mounting base, namely the first profile protective barrier 1 and the second profile protective barrier 2. If one first profile protective barrier 1 can be set, one or more second profile protective barriers 2 can be set outside the first profile protective barrier 1. The inner ring of the protective barrier is the first profile protective barrier 1, and the outer ring is the second profile protective barrier 2. The first profile protective barrier 1 is installed on the profile mounting base. If it can be set to L-shaped, arc-shaped, arc-shaped with folded edges at both ends, or trapezoidal; the material can be stainless steel, aluminum, iron, plastic, etc. If it is used for Mauser pistol, even profiles made of thick paper can be used (hereinafter referred to as profiles for the sake of convenience). The first profile protective barrier 1 is installed on the inner ring, and the second profile protective barrier 2 is installed on the outer ring. There is a certain distance between two adjacent first profiles 1-1 of the first profile protective barrier 1, which is the first sound outlet 6 (see Figure 3 The first profile 1-1 of the first protective barrier 1 and the second profile 2-1 of the second protective barrier 2 have a certain distance between them for sound transmission. The second passage 7 (see...) Figure 3 That is, each of the two adjacent profiles in the front, back, left, and right directions is equipped with a sound outlet (see...). Figure 3 , Figure 4 This creates an open space for sound (which can be redirected), while the profiles act as a closed space for firecracker debris and ash, trapping the fine ash within the protective walls. Thus, the firecracker debris and ash can only fall onto the chassis. The first profile protective wall 1 and the second profile protective wall 2, together with the top cover 5 and the chassis 9, form a firecracker firing chamber 11.

[0054] Specifically, this invention discloses a series of firecracker safety firing box. The number and size of the various profiles can be arbitrarily selected, as long as they can be arranged into a barrel-shaped structure. Generally, there are 6 to 20 profiles per ring (the size can be appropriately increased when used in large event venues such as hotels and weddings, while also taking into account the size of the profiles). In this embodiment, each ring is set to 10 profiles.

[0055] The firing box includes: a first profile protective barrier 1, a first profile 1-1, a second profile protective barrier 2, a second profile 2-1, a first sound inlet 6, a second sound inlet 7, a top cover 5, a chassis 9, a firecracker firing chamber 11, a firecracker ignition port, and a profile mounting base.

[0056] Its features are: The first profile 1-1 of the first profile protective barrier 1 is spaced with the first profile 1-1 of the adjacent first profile protective barrier 1, forming the first sound passage 6; The second profile protective barrier 2 is set on the outer ring of the first profile protective barrier 1.

[0057] At least two protective retaining walls are installed on the profile mounting base, namely the first profile protective retaining wall 1 and the second profile protective retaining wall 2; alternatively, only one first profile protective retaining wall 1 may be installed, and one or more second profile protective retaining walls 2 may be added on its outer side. The openings or open edges of the first profile protective retaining wall 1, the profile, and the second profile protective retaining wall 2 all face inward.

[0058] The profile can be L-shaped, arc-shaped, arc-shaped with folded edges at both ends, trapezoidal, or grooved; the material can be stainless steel, aluminum, iron, plastic, etc.; when used for small gift box-type fireworks boxes (commonly known as box cannons), thick paper profiles (hereinafter referred to as profiles) can also be used. With the development of technology, new materials are constantly emerging, which will not be listed here.

[0059] A protective barrier is formed by several profiles erected vertically, with the inner circle being the first profile protective barrier 1 and the outer circle being the second profile protective barrier 2.

[0060] In the first profile protective retaining wall 1, there is a gap between two adjacent first profiles 1-1 to form the first sound passage 6; A gap is provided between the first profile 1-1 of the first profile protective barrier 1 and the second profile 2-1 of the second profile protective barrier 2 to form a second sound outlet 7; The spacing between two adjacent second profiles 2-1 is the third sound outlet 13; that is, there are sound outlets between two adjacent profiles in the front, back, left and right. In other words, there are sound outlets between two adjacent first profiles 1-1, between the first profile 1-1 and the adjacent second profile 2-1, and between two adjacent second profiles 2-1. Because the first profile 1-1 and the second profile 2-1 are staggered, each first sound outlet 6 is blocked by the corresponding second profile. This prevents firecracker debris from exiting the first profile protective barrier 1 from escaping in a straight line through the gaps formed between adjacent second profiles 2-1 in the second profile protective barrier 2. Instead, the debris is blocked by the corresponding second profile 2-1. However, the sound can be redirected and transmitted through the gaps formed between adjacent second profiles 2-1 in the second profile protective barrier 2. This structure allows the sound of firecrackers to be directionally conducted and diffused, forming a relatively open sound transmission space. At the same time, it forms a closed blocking space for firecracker debris and ash powder, confining fine ash powder within the protective wall through the profile barrier, so that firecracker debris and ash powder can only fall onto the chassis 9.

[0061] The first profile protective barrier 1, the second profile protective barrier 2, together with the top cover 5 and the chassis 9, form a closed firecracker firing chamber 11.

[0062] Example 2: A series of firecracker safety firing boxes includes a first profile protective barrier 1, a top cover 5, a base 9, a firecracker firing chamber 11, and a profile mounting base. The first profile protective barrier 1 is a firecracker safety firing box formed by several first profiles 1-1 enclosing a barrel shape. The box is characterized by further including a second profile protective barrier 2, which is formed by several second profiles 2-1 enclosing a barrel shape (see...). Figure 21 Both the first profile 1-1 and the second profile 2-1 are U-shaped profiles. The openings (also called open edges in this invention) of the U-shaped profiles used in the first profile protective barrier 1 face outwards. The openings (open edges) of the U-shaped profiles used in the second profile protective barrier 2 face inwards. The openings of the first profile 1-1 and the second profile 2-1 are staggered and opposite to each other (see...). Figure 24 Furthermore, a certain distance is provided between two adjacent second profiles 2-1; the opening (empty edge) of each first profile 1-1 is set towards the opening (empty edge) of two adjacent second profiles 2-1, and the groove-shaped profile opening of the first profile 1-1 covers the aforementioned certain distance between adjacent second profiles 2-1 (see...). Figure 24 and Figure 25 At the same time, it covers the partial groove openings of the two adjacent second profiles 2-1, so that a gap is formed between the first profile 1-1 and the corresponding second profile 2-1. This gap is the second sound outlet 7 (see Figure 21 , Figure 24 and Figure 25 In the first profile protective barrier 1, the spacing between two adjacent first profiles 1-1 is the first sound outlet 6, and the spacing between two adjacent second profiles 2-1 is the third sound outlet 13 (see...). Figure 21 , Figure 24 and Figure 25 This means that sound vents are provided between any two adjacent profiles on the front, back, left, and right sides. Specifically, sound vents are provided between two adjacent first profiles 1-1, between the first profile 1-1 and the adjacent second profile 2-1, and between two adjacent second profiles 2-1. The first profile protective barrier 1 is located in the inner ring, and the second profile protective barrier 2 is located in the outer ring (see...). Figure 21 , Figure 24 and Figure 25Both the first and second profiles are fixed on the profile mounting base, and the two profile protective walls are independent protective structures. The overall protective wall consists of two rings of profiles forming a protective barrel. Since the inner ring of the first profile protective wall 1 has a mesh protective cylinder 10, most of the debris will be blocked in the mesh protective cylinder 10. Since the openings of the first profile 1-1 and the second profile 2-1 are staggered, when a small amount of debris enters the first sound outlet 6, some of the debris will remain in the first sound outlet 6 and fall onto the chassis 9. Others will disperse towards the second sound outlets 7 on both sides and, when they hit the edges of the second profile, they will stay in the second sound outlet 7 and then fall onto the chassis. Although the debris is blocked inside the winding sound channel, that is, because the openings of the first profile 1-1 and the second profile 2-1 are staggered, most of the debris will be blocked in the mesh protective cylinder 10. The openings of the -1 are staggered, preventing firecracker debris from exiting the first profile protective barrier 1 from escaping in a straight line through the gaps formed between adjacent second profiles 2-1 of the second profile protective barrier 2. Instead, the debris is blocked by the opposing second profiles 2-1. Since sound can be redirected, the original sound of the firecracker is transmitted through the gaps formed between adjacent second profiles 2-1 of the second profile protective barrier 2. The cavity formed by the first profile protective barrier 1, the second profile protective barrier 2, the upper cover 5, and the chassis 9 is the firecracker firing chamber 11 (see...). Figure 6 and Figure 18 ).

[0063] Example 3 This embodiment is based on Example 1 or 2, with the following parameters set: The width w2 of the first sound outlet 6 is smaller than the width w1 of the profile opening of the second profile protective barrier 2, wherein the profile opening width is the distance between the two sides of the profile opening of the second profile protective barrier 2. The width w3 of the second sound outlet 7 is smaller than the width w2 of the first sound outlet 6 (see...). Figure 3 and Figure 25 ).

[0064] Furthermore, the firecracker firing chamber is equipped with a series of firecracker placement mechanisms (such as hooks), and the upper cover 5 of the protective wall enclosed by profiles is a circular or square mesh structure (see...). Figure 11 and Figure 29 The top cover or protective barrier is equipped with ignition ports for setting off firecrackers, or the base is provided. The hollow edge of the profile faces the inner circle of the protective barrier.

[0065] Furthermore, the structure of the profile mounting base for the first profile protective barrier 1 and the second profile protective barrier 2 can be configured as a flat, hollow type (see...). Figure 3 ) or slotted rail type (see Figure 26To prevent debris and powder from remaining inside the groove, the bottom edge of the groove can be hollowed out and multiple flat strips can be used to fix and connect the two grooves (mounting seats). Essentially, the bottom edge of the groove simply connects the two grooves (mounting seats) together. There are various processing methods, which will not be listed here. The flat hollow type involves fixing both ends of the profile to the flat hollow profile mounting seat, while the groove-rail type mounting seat fixes the two side edges of the profile to the groove. The profile mounting seat can be configured as an upper profile mounting seat 4 and a lower profile mounting seat 3, or it can be a single profile mounting seat. To provide an additional layer of protection, a mesh protective cylinder 10 is installed inside the first profile protective barrier. Preferably, the mesh protective cylinder 10 is coaxially positioned within the inner ring of the first profile protective barrier 1 (either fixed to the inner surface of the first profile protective barrier 1 or fitted inside the inner surface of the first profile protective barrier 1), forming a firecracker firing chamber 11 with the top cover 5 and the base 9; the mesh protective cylinder 10 (see...) Figure 9 and Figure 27 The mesh protective tube 10 (which can be round or square) is used to contain larger firecracker debris within the firecracker firing chamber 11. However, finer powder, such as gunpowder dust, can still escape. Since a mesh alone cannot effectively block this powder, a first protective barrier 1-1 is used to contain the firecracker debris and powder within the firing chamber 11. The bottom of the mesh protective tube 10 is higher than the top of the chassis 9, creating a gap between them. This allows for better sound transmission from the bottom sound outlet.

[0066] Furthermore, the profiles of the first and second profile protective barriers used in the aforementioned series-shaped firecracker safety firing box can be set in an L-shape (see...). Figure 4 Semicircular arc (see) Figure 15 ) or an arc shape with folded edges at both ends (see Figure 12 Or a triangular trapezoidal tube with its parallel long sides being the open sides (see...). Figure 14 ) or grooved profiles (see Figure 13 The trapezoidal tube is typically open by removing the longer sides of the two parallel sides. The grooved profile is typically an unequal-sided square tube, with one long side removed to form the open side. If the overall structure of Example 2 is changed from square to circular, the middle edge (bottom edge) of the grooved profile can be rounded to the size of the circle. For example, when used in the inner ring (as the first protective barrier), it arches outward (towards the open side), while when used in the outer ring (as the second protective barrier), it arches outward (towards the opposite direction of the open side). This will result in a better effect and a more aesthetically pleasing, rounded shape.

[0067] Furthermore, the aforementioned series-shaped firecracker safety firing box is characterized in that: a series-shaped firecracker placement mechanism is provided within a space formed by the first profile protective barrier 1, the upper cover 5, and the base 9 for firing firecrackers. The firecracker placement mechanism can be configured as a wave shape, a spiral surface shape, a hanging shape, or a flat disc shape, that is, the configuration of the firecracker placement mechanism includes four types, namely a wave-shaped structure (see Figure 17), a spiral surface structure (see Figure 16), a flat disc structure, and a hanging structure (not shown in the figure).

[0068] Furthermore, the aforementioned series-shaped firecracker safety firing box is characterized in that: the barrel-shaped body formed by the first profile 1-1 of the first profile protective barrier 1, and the barrel-shaped body formed by the second profile 2-1 of the second profile protective barrier 2, wherein the cross-section of the barrel-shaped body is circular, elliptical, rectangular, square, or polygonal. The shape and height can be customized as needed, and will not be described further here.

[0069] Furthermore, the aforementioned series-shaped firecracker safety firing box is characterized in that: the base 9 is configured with a surrounding edge, and the outer perimeter of the base 9 is slightly larger than the profile mounting base 3; the distance between the outer perimeter of the base 9 and the profile mounting base 3 is the outlet of the bottom sound inlet 8 (see...). Figure 7 and Figure 20 The distance between the outer perimeter of the chassis 9 and the profile mounting base 3 is usually no greater than the distance between the profile mounting base and the chassis; the profile mounting base 3 and the upper plate surface of the chassis 9 are provided with a distance by screws 12 or support feet, which constitutes the bottom sound vent 8 (see...). Figure 7 and Figure 20 The perimeter of the mesh protective cylinder 10 extends to the base 9, and the bottom surface of the mesh protective cylinder 10 is slightly higher than the circumference of the bottom edge of the base 9 (the circumference is only to prevent debris from flying out; being too high is not very meaningful and will instead distort the transmitted sound, so it is usually no more than 50mm higher), creating a certain distance between the bottom surface of the mesh protective cylinder 10 and the surface of the base 9 (see...). Figure 7 , Figure 20 The mesh protective tube 10 should generally not be higher than the edge of the chassis 9. This way, firecracker debris will remain in the mesh protective tube 10, while finer powder will fall into the chassis 9 through the mesh.

[0070] Further precautions for manufacturing and assembling the chain-type firecracker safety firing box: 1. Profile Dimensions and Precision Control: The length, bending angle, and groove depth of the first profile 1-1 and the second profile 2-1 must be uniform to ensure interchangeability. The opening size and wall thickness of the grooved (U-shaped) profiles should be uniform to avoid deformation and warping, ensuring consistent gaps after assembly.

[0071] 2. In the structure of Example 1, the staggered installation of the inner and outer ring profiles must strictly ensure that: the openings of the first inner ring profile 1-1 all face inward; the openings of the second outer ring profile 2-1 all face inward; each first profile 1-1 must be aligned with the gap between two adjacent second profiles 2-1 to achieve staggered shielding. The opening directions of the inner and outer ring profiles must not be reversed, otherwise the chip blocking and sound transmission effects will be lost.

[0072] 3. In the structure of Example 2, the staggered installation of the inner and outer ring profiles must strictly adhere to the following requirements: all openings of the first inner ring profile 1-1 must face outwards; all openings of the second outer ring profile 2-1 must face inwards; each first ring profile 1-1 must be aligned with the gap between two adjacent second ring profiles 2-1 to achieve staggered blocking and ensure that the sound passage forms a labyrinth structure. The opening directions of the inner and outer ring profiles must not be reversed, otherwise the chip blocking and sound transmission effects will be lost.

[0073] 4. Sound outlet spacing control: The spacing of the first sound outlets 6 between adjacent first profiles 1-1 should be as uniform as possible. The gap size between adjacent second profiles 2-1 should be uniform to ensure smooth sound transmission and prevent debris from splashing out.

[0074] 5. Installation requirements for mesh protective cylinders: The mesh protective cylinder 10 should be compatible with the inner ring of the first profile protective retaining wall 1. The mesh size should be moderate, enough to block large debris without significantly obstructing sound transmission.

[0075] 6. Overall structural strength and safety: Components such as profiles, mounting bases, and mesh protective cylinders are made of flame-retardant, high-temperature resistant, and impact-resistant materials. All connections are strong enough to withstand the impact of firecracker explosions without cracking or deforming.
