Description

Technical Field

[0001] The utility model relates to a sound-generating device, in particular to an instantaneous sound-generating device. Background Art

[0002] Nowadays, the blasting structure used to make a sudden sound is usually made of a sealed structure, gunpowder and fuse. The gunpowder is loaded into the sealed structure. When the fuse is ignited, the gunpowder inside the sealed structure begins to burn and generates a large amount of gas and pressure. The generated gas and pressure are released instantly, causing the sealed structure to explode, thereby generating sound;

[0003] Gunpowder will produce a large amount of smoke and harmful gases during the combustion process. When the sealing structure is not tightly sealed, the gunpowder may leak out. At this time, igniting the fuse will cause the internal gunpowder and the leaked gunpowder to burn rapidly. The combustion of the leaked gunpowder is uncontrollable and can easily cause safety accidents. In recent years, due to the safety and environmental problems caused by the setting off of fireworks and firecrackers, many places have implemented bans on firecrackers. Utility Model Content

[0004] The utility model aims to provide an instant sounding device, and the technical problem to be solved is to improve the control accuracy of the blasting structure.

[0005] The utility model is realized by the following technical solutions:

[0006] An instantaneous sound generating device, comprising:

[0007] A pressure tank, wherein the pressure tank is provided with a chamber, a sealing plug and a gas port, wherein the chamber and the gas port are connected; the chamber is used to load compressed gas, the gas pressure of the compressed gas is greater than the external air pressure; the sealing plug is sleeved in the gas port, and the sealing plug is used to seal the gas port, and after sealing the gas port, the sealing plug has a tendency to pop outward;

[0008] The limiting assembly comprises a limiting cylinder and a limiting member, wherein the limiting member is connected to the limiting cylinder; the limiting cylinder is rotatably connected to the pressure tank;

[0009] Wherein, a limiting groove is provided on the limiting member, and a limiting block is provided on the pressure tank, and the limiting block is clamped in the limiting groove;

[0010] When the limiting block is clamped in the limiting groove, the limiting member abuts against the sealing plug to limit the sealing plug in the air port;

[0011] The limiting cylinder is rotated, and the limiting block gradually moves out of the limiting groove. When the limiting block moves out of the limiting groove, the sealing plug pops outward.

[0012] By rotating the above-mentioned limit cylinder, the separation process of the limit block and the limit groove is controlled. The separation process is linear and controllable. Compared with the traditional direct removal or firing method, it reduces the uncertainty in the operation process and helps to achieve the expected blasting time; the existence of the limit assembly is equivalent to setting a safety lock. Only under clear and conscious rotation operation can the lock of the sealing plug be released, which reduces the risk of premature ejection of the sealing plug due to accidental touch or vibration, improves the safety and reliability of the device, and also ensures the control accuracy of the sound release; when the sealing plug is not unlocked, it is continuously pressed by the limit member, which can maintain a good seal with the gas port, reduce gas leakage caused by long-term storage, and ensure that sufficient gas pressure can still be provided when triggered to produce the expected sound intensity; due to the rotation design of the limit assembly, after releasing a sound, the device can refill the compressed gas into the pressure tank, and by rotating the limit cylinder in the opposite direction, the limit block is re-engaged in the limit groove, and the sealing plug is locked again, so that the device has the characteristics of reusability.

[0013] Furthermore, a slide rail is arranged along the circumference of the outer side wall of the pressure tank, and a slide groove is arranged along the circumference of the inner side wall of the limiting cylinder, and the slide groove is adapted to the slide rail.

[0014] The coordinated design of the above-mentioned slide rail and slide groove ensures that the limit cylinder can only rotate smoothly along the preset rotation axis (i.e., the direction of the slide rail) relative to the pressure tank, avoiding unstable phenomena such as deflection and shaking; this directional guidance mechanism is beneficial for the operator to control the rotation angle of the limit cylinder, and then control the separation process of the limit block and the limit groove, thereby improving the control accuracy of the sound release.

[0015] Furthermore, the above-mentioned limiting member includes a connecting plate and an abutting plate, and two ends of the above-mentioned connecting plate are respectively connected to the limiting cylinder and the abutting plate;

[0016] The end of the abutting plate is bent to form a limiting groove.

[0017] The above-mentioned connecting plate is mainly responsible for the connection with the limit cylinder to ensure that the limit part rotates synchronously with the limit cylinder; the abutment plate is responsible for the task of contacting and limiting the sealing plug. This design with clear functional divisions is conducive to improving the mechanical properties and work efficiency of each part; the end of the abutment plate is bent to form a limit groove, so that the limit groove is directly integrated on the abutment plate, with a simple structure and easy processing and manufacturing; multi-point contact is formed between the limit groove formed by the bending of the end of the abutment plate and the limit block, which increases the contact area and improves the stability of the limit, especially in vibration or impact environments, this multi-point contact design can better maintain the limit state, avoid the risk of tripping due to excessive force on a single point, and further ensure the control accuracy of the sound release.

[0018] Furthermore, the above-mentioned limit blocks are provided in plurality, and the interval between adjacent limit blocks is greater than the length of the limit slot.

[0019] Setting a plurality of the above-mentioned limit blocks, with the interval between adjacent limit blocks being greater than the length of the limit slot, means that each time the limit cylinder is rotated, the limit slot can only cooperate with one limit block. In this way, the operator can control the rotation angle of the limit cylinder to achieve fine-tuning of the sound release process. Especially in cases where fine control of the sound intensity, rhythm or frequency is required, this design provides extremely high adjustment accuracy; the multi-limit block design increases the safety redundancy of the device. Even if one of the limit blocks fails for some reason, the other limit blocks can still maintain the stable limit of the sealing plug to prevent accidental release of compressed gas.

[0020] Furthermore, a slot is provided on the above-mentioned limiting cylinder;

[0021] When the limiting block is clamped in the limiting groove, the connecting plate is arranged in the clamping groove and abuts against the limiting cylinder;

[0022] When the limiting block moves out of the limiting groove, the connecting plate moves in the slot.

[0023] The existence of the above-mentioned slot provides a clear positioning reference for the connecting plate. When the limit block is engaged with the limit slot, the connecting plate is just embedded in the slot, ensuring that the contact position of the abutment plate and the sealing plug is correct; this positioning helps to improve the stability of the sound release and avoid distortion of the sound effect caused by position deviation; the cooperation between the above-mentioned slot and the connecting plate increases the contact area and constraint force between the limit cylinder and the limit member, and enhances the connection stability between the two. During operation, whether it is maintaining the limit state or rotating to unlock, it can effectively prevent the two from sliding relative to each other or loosening, ensuring the accuracy of sound release control while avoiding the limit member from detaching and popping out, causing safety accidents; the above-mentioned slot not only limits the position of the connecting plate, but also provides a guiding effect for the connecting plate when the limit cylinder rotates. When the limit cylinder rotates, the connecting plate moves along the preset path in the slot, ensuring that the separation process of the abutment plate and the limit slot is smooth and orderly, avoiding abnormal sound release caused by deviation of the motion trajectory.

[0024] Furthermore, one end of the connecting plate connected to the limiting cylinder is tilted upward to form a curved surface;

[0025] When the limiting block is clamped in the limiting groove, the curved surface abuts against the limiting cylinder.

[0026] The upward curved surface design makes the transition between the connecting plate and the limit cylinder smoother, reduces stress concentration that may be caused by structural mutations, and helps protect components from impact damage; during the rotation and unlocking process of the limit cylinder, the smooth transition of the curved surface also helps to reduce vibration and noise, improving user experience.

[0027] Furthermore, the outer wall of the limiting cylinder is sleeved with a first sleeve, and the first sleeve extends out of the top of the limiting cylinder;

[0028] A film is provided on the top of the first sleeve, and the film is used to seal the top of the first sleeve.

[0029] The above-mentioned first sleeve serves as an additional protective layer, covering the outside of the limit cylinder, which can effectively resist the invasion of dust, moisture, corrosive substances, etc. in the external environment on the limit cylinder and its internal components (such as connecting plates, limit grooves, etc.), thereby extending the service life of the device and ensuring its stable operation in complex environments; a thin film is arranged on the top of the first sleeve to achieve sealing of the top opening of the first sleeve to prevent external pollutants from entering the interior of the first sleeve.

[0030] Furthermore, the outer wall of the first sleeve is sleeved with a second sleeve, and the second sleeve extends out of the top of the first sleeve;

[0031] A cover plate is provided on the top of the second sleeve, and the cover plate is used to seal the top of the second sleeve;

[0032] The second sleeve contains decorative objects.

[0033] The second sleeve as the second layer of protection structure is superimposed on the first sleeve, providing tighter protection for the internal components. Especially for those occasions with high environmental sensitivity or strict sealing requirements, double protection significantly improves the working reliability of the device; the decorations in the second sleeve, such as colored beads and sequins, etc., when the compressed gas is ejected from the pressure tank, the compressed gas successively breaks through the film and cover plate, and pushes the decorations out of the second sleeve, thereby increasing the fun and appreciation of the device and making it more personalized; a cover plate is set on the top of the second sleeve to prevent the decorations from leaking out when the pressure tank does not eject compressed gas.

[0034] Furthermore, the outer side wall of the pressure tank is coated with an aluminum film.

[0035] Aluminum film has high reflectivity and can reflect most of the solar radiation heat, reduce the surface temperature of the pressure tank, and reduce the rapid expansion of the gas inside the pressure tank caused by high temperature, which is conducive to maintaining the stability of the internal gas pressure and ensuring the accuracy of sound release. In addition, aluminum film can also help prevent high temperature from damaging the material of the pressure tank and extend its service life.

[0036] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0037] By rotating the above-mentioned limit cylinder, the separation process of the limit block and the limit groove is controlled. This process is linear and controllable. Compared with the traditional direct removal or firing method, it reduces the uncertainty in the operation process, makes the activation of the sound device more accurate, and helps to achieve the expected blasting time; the existence of the limit assembly is equivalent to setting a safety lock, and the sealing plug can only be unlocked under clear and conscious rotation operation; the risk of premature ejection of the sealing plug due to accidental touch or vibration is reduced, the safety and reliability of the device are improved, and the control accuracy of the sound release is also guaranteed; when the sealing plug is not unlocked, it is continuously pressed by the limit member, which can maintain a good seal with the gas port, reduce gas leakage caused by long-term storage, and ensure that sufficient gas pressure can still be provided when triggered to produce the expected sound intensity; due to the rotation design of the limit assembly, after releasing a sound, the device can refill the pressure tank with compressed gas, and the limit block can be re-engaged in the limit groove by rotating the limit cylinder in the opposite direction, and the sealing plug can be locked again, so that the device has the characteristics of reusability.

[0047] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the utility model and their descriptions are only used to explain the utility model and are not intended to limit the utility model.

[0048] Example 1: Combination Figure 1 , Figure 2 and Figure 3 , this embodiment 1 provides an instantaneous sound generating device, comprising:

[0049] A pressure tank 10, wherein the pressure tank 10 is provided with a chamber, a sealing plug 12 and a gas port, wherein the chamber and the gas port are in communication; the chamber is used to carry compressed gas, the gas pressure of the compressed gas is greater than the external pressure; the sealing plug 12 is sleeved in the gas port, and the sealing plug 12 is used to block the gas port, and after blocking the gas port, the sealing plug 12 has a tendency to pop outward;

[0050] The limiting assembly includes a limiting cylinder 22 and a limiting member 21, wherein the limiting member 21 is connected to the limiting cylinder 22; the limiting cylinder 22 is rotatably connected to the pressure tank 10;

[0051] The limiting member 21 is provided with a limiting groove 26, and the pressure tank 10 is provided with a limiting block 11, and the limiting block 11 is clamped in the limiting groove 26;

[0052] When the limiting block 11 is engaged with the limiting groove 26, the limiting member 21 abuts against the sealing plug 12 to limit the sealing plug 12 in the air port;

[0053] By rotating the limiting cylinder 22 , the limiting block 11 gradually moves out of the limiting groove 26 . When the limiting block 11 moves out of the limiting groove 26 , the sealing plug 12 pops outward.

[0054] The chamber in the pressure tank 10 is used to carry high-pressure compressed gas, and its internal air pressure is significantly higher than the external environmental air pressure, which ensures that sufficient energy is stored and a strong sound can be generated when the gas is released instantly; the sealing plug 12 is used to seal the gas port, which plays a role in closing the gas port to prevent the compressed gas from escaping at unpredictable times. When the sealing plug 12 is in the state of sealing the gas port, it has a tendency to pop outward due to the force of the internal high-pressure gas, which is the key to achieving instant release; the limiting cylinder 22 in the limiting assembly is rotatably connected to the pressure tank 10, and the relative position between the limiting member 21 and the sealing plug 12 is controlled by a rotating action; the limiting member 21 on the limiting member 21 The groove 26 is used to receive the limit block 11 on the pressure tank 10. The limit member 21 is in direct contact with the sealing plug 12 to mechanically lock the sealing plug 12 to prevent it from popping out prematurely due to the internal high pressure. The limit block 11 cooperates with the limit groove 26 to form a clamping structure. When the limit block 11 is stuck in the limit groove 26, a retaining force in the opposite direction of the internal air pressure is applied to the sealing plug 12 through the limit member 21 to ensure that the sealing plug 12 firmly seals the air port. The limit groove 26 allows the limit block 11 to slide and disengage inside it. When the limit cylinder 22 rotates, the relative position between the limit block 11 and the limit groove 26 changes until the limit block 11 is completely moved out of the limit groove 26.

[0055] In summary, high-precision control of the compressed gas release process is achieved through the pressure tank 10, the limit assembly, the limit block 11 and the limit groove 26. Its advantages include triggering accuracy, anti-mistouch protection, stable sealing performance and reusability, which together improve the control accuracy of the blasting structure and ensure the accuracy and consistency of the sound effect.

[0056] Example 2: Based on Example 1, Figure 4 The outer wall of the pressure tank 10 is provided with a slide rail 13 along the circumference, and the inner wall of the limiting cylinder 22 is provided with a slide groove (not shown in the figure) along the circumference, and the slide groove is adapted to the slide rail 13.

[0057] The design of the slide rail 13 and the slide groove ensures that the limit cylinder 22 can only rotate smoothly along the preset rotation axis (i.e., the direction of the slide rail 13) relative to the pressure tank 10, avoiding unstable phenomena such as deflection and shaking; this directional guidance mechanism is conducive to the operator to control the rotation angle of the limit cylinder 22, thereby controlling the separation process of the limit block 11 and the limit groove 26, and improving the control accuracy of the sound release; the close cooperation between the slide rail 13 and the slide groove not only limits the degree of freedom of the limit cylinder 22, but also provides additional support and positioning, thereby enhancing the stability of the entire device during operation. Even in a vibration or slight impact environment, it can effectively prevent the limit cylinder 22 from accidentally deflecting or loosening, ensuring the reliable maintenance or unlocking of the limit state; the contact surface between the slide rail 13 and the slide groove is relatively smooth, which reduces the friction resistance of the limit cylinder 22 during rotation, reduces the wear rate, and prolongs the service life of the device. At the same time, good sliding contact also helps to maintain the smoothness of the rotation of the limit cylinder 22, making the operation feel better and further improving the control accuracy.

[0058] Embodiment 3: Based on any of the above embodiments, the above-mentioned limiting member 21 includes a connecting plate 24 and an abutting plate 25, and the two ends of the above-mentioned connecting plate 24 are respectively connected to the limiting cylinder 22 and the abutting plate 25;

[0059] The corresponding end of the abutment plate 25 is bent to form a corresponding limiting groove 26. Figure 5 shown.

[0060] The above-mentioned connecting plate 24 is mainly responsible for the connection with the limiting cylinder 22 to ensure that the limiting member 21 rotates synchronously with the limiting cylinder 22; the abutment plate 25 is responsible for the task of contacting with the sealing plug 12 and limiting it. This design with clear functional divisions is conducive to improving the mechanical properties and work efficiency of each part; the end of the above-mentioned abutment plate 25 is bent to form a limiting groove 26, so that the limiting groove 26 is directly integrated on the abutment plate 25, with a simple structure and easy processing and manufacturing; the limiting groove 26 formed by the bending of the end of the abutment plate 25 forms multiple points of contact with the limiting block 11, which increases the contact area and improves the stability of the limit, especially in a vibration or impact environment, this multi-point contact design can better maintain the limiting state, avoid the risk of tripping due to excessive force on a single point, and further ensure the control accuracy of the sound release.

[0061] Embodiment 4: Based on Embodiment 3, Figure 1 There are two limit blocks 11 , which are arranged opposite to each other, and the interval between adjacent limit blocks 11 is greater than the length of the limit slot 26 .

[0062] A plurality of the above-mentioned limit blocks 11 are provided, and the interval between adjacent limit blocks 11 is greater than the length of the limit slot 26, which means that each time the limit cylinder 22 is rotated, the limit slot 26 can only cooperate with one limit block 11. In this way, the operator can control the rotation angle of the limit cylinder 22 to achieve fine-tuning of the sound release process. Especially in cases where fine control of the sound intensity, rhythm or frequency is required, this design provides extremely high adjustment accuracy; the design of multiple limit blocks 11 increases the safety redundancy of the device. Even if one of the limit blocks 11 fails for some reason, the other limit blocks 11 can still maintain the stable limit of the sealing plug 12 to prevent accidental release of compressed gas.

[0063] Embodiment 5: Based on any of the above embodiments, Figure 3 , the above-mentioned limiting cylinder 22 is provided with a card slot 23;

[0064] When the above-mentioned limiting block 11 is clamped in the limiting groove 26, the connecting plate 24 is arranged in the clamping groove 23 and abuts against the limiting tube 22;

[0065] When the limiting block 11 moves out of the limiting groove 26 , the connecting plate 24 moves in the clamping groove 23 .

[0066] The existence of the above-mentioned slot 23 provides a clear positioning reference for the connecting plate 24. When the limit block 11 is engaged with the limit slot 26, the connecting plate 24 is just embedded in the slot 23, ensuring that the contact position of the abutment plate 25 and the sealing plug 12 is correct; this positioning helps to improve the stability of the sound release and avoid distortion of the sound effect caused by position deviation; the cooperation between the above-mentioned slot 23 and the connecting plate 24 increases the contact area and restraint force between the limit cylinder 22 and the limit member 21, and enhances the connection stability between the two. During operation, whether it is maintaining the limit state or rotating to unlock, it can effectively prevent the two from relative movement. The above-mentioned slot 23 not only limits the position of the connecting plate 24, but also provides a guide for the connecting plate 24 when the limiting cylinder 22 rotates. When the limiting cylinder 22 rotates, the connecting plate 24 moves along a preset path in the slot 23, ensuring that the separation process of the abutment plate 25 and the limiting slot 26 is smooth and orderly, avoiding abnormal sound release caused by deviation of the motion trajectory. The design of the above-mentioned slot 23 simplifies the assembly process of the limiting cylinder 22 and the limiting member 21. The connection can be easily completed by aligning the connecting plate 24 with the slot 23.

[0067] Specific embodiments, combined with Figure 2 , one end of the connecting plate 24 connected to the limiting cylinder 22 is tilted upward to form a curved surface;

[0068] When the limiting block 11 is engaged in the limiting groove 26 , the curved surface abuts against the limiting tube 22 .

[0069] The upward curved surface design makes the transition between the connecting plate 24 and the limiting cylinder 22 smoother, reduces the stress concentration that may be caused by structural mutations, and helps protect the components from impact damage; during the rotation and unlocking process of the limiting cylinder 22, the smooth transition of the curved surface also helps to reduce vibration and noise, thereby improving the user experience.

[0070] Embodiment 6: Based on any of the above embodiments, Figure 6 The outer wall of the limiting cylinder 22 is sleeved with a first sleeve 30, and the first sleeve 30 extends out of the top of the limiting cylinder 22;

[0071] A film 31 is provided on the top of the first sleeve 30 , and the film 31 is used to seal the top of the first sleeve 30 .

[0072] The film 31 can only be used once. When the device is reused, the film 31 needs to be replaced. The above-mentioned first sleeve 30 serves as an additional protective layer, covering the outside of the limit cylinder 22, and can effectively resist the invasion of dust, moisture, corrosive substances, etc. in the external environment on the limit cylinder 22 and its internal components (such as the connecting plate 24, the limit groove 26, etc.), thereby extending the service life of the device and ensuring its stable operation in a complex environment. A film 31 is arranged on the top of the first sleeve 30 to achieve sealing of the top opening of the first sleeve 30 and prevent external pollutants from entering the first sleeve 30.

[0073] If a transparent or translucent film 31 material is selected, it is also possible to intuitively observe the internal conditions of the limit cylinder 22 (such as the relative position relationship between the limit block 11 and the limit groove 26). This greatly improves the visualization and operational convenience of the device for application scenarios that require real-time monitoring of the progress or status of sound release.

[0074] In a specific embodiment, the outer wall of the first sleeve 30 is sleeved with a second sleeve 40, and the second sleeve 40 extends out of the top of the first sleeve 30;

[0075] A cover plate 41 is provided on the top of the second sleeve 40, and the cover plate 41 is used to seal the top of the second sleeve 40;

[0076] The second sleeve 40 contains decorative objects.

[0077] The second sleeve 40 is a second layer of protective structure, which is superimposed on the first sleeve 30, providing a more stringent protection for the internal components. Especially for those occasions with high environmental sensitivity or strict requirements on sealing, the double protection significantly improves the working reliability of the device; the decorations contained in the second sleeve 40, such as colored beads and sequins, when the compressed gas is ejected from the pressure tank 10, the compressed gas successively breaks through the film 31 and the cover plate 41, and pushes the decorations out of the second sleeve 40, thereby increasing the fun and ornamental value of the device, making it more personalized, and mainly used in fireworks; a cover plate 41 is set on the top of the second sleeve 40 to prevent the decorations from leaking out when the pressure tank 10 does not eject compressed gas.

[0078] Embodiment 7: Based on any of the above embodiments, the outer wall of the pressure tank 10 is coated with an aluminum film.

[0079] The aluminum film has a high reflectivity and can reflect most of the solar radiation heat, reduce the surface temperature of the pressure tank 10, reduce the excessive expansion of the internal gas of the pressure tank 10 caused by high temperature, and help maintain the internal gas pressure stable and ensure the accuracy of sound release. In addition, the aluminum film also helps prevent high temperature from damaging the material of the pressure tank 10 and prolong its service life.

[0080] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
