[0002] According to Chinese Publication No. CN213714108U, a pull-type colored smoke canister includes an outer canister, an inner canister located inside the outer canister, a colored smoke agent installed in the inner canister, an ignition powder located in the inner canister for igniting the colored smoke agent, a pull-type delay tube located in the inner canister, an inner canister lid covering the inner canister, and an outer canister lid for safety protection. The pull-type delay tube has a fuse connected to a pull ring located between the outer canister lid and the inner canister lid. The inner canister lid has a smoke-emitting hole.

[0003] The smoke generators described above and in the prior art produce dense smoke by igniting a solid combustible material containing smoke-generating agents. The composition of the smoke-generating agent and the combustion method determine that the amount and speed of smoke generation are relatively fixed, but the size of the existing exhaust port is fixed. Once ignited, the smoke-generating agent will continue to burn until it is exhausted, making it difficult to adjust the amount of smoke produced according to actual needs during use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where it is difficult to adjust the amount of smoke produced according to actual needs during use, and to propose a controllable release smoke generator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a controllable release smoke generator canister, comprising a canister body, two locking blocks on the outer surface of the top of the canister body, a smoke generator inside the canister body, an inner cover on the top of the smoke generator, a through hole on the surface of the inner cover, a lead wire inside the through hole, a canister lid on the top of the canister body, three smoke vents on the top surface of the canister lid, a baffle on the top surface of the canister lid, a fixing frame on the outside of the canister lid, a rotating groove on the surface of the fixing frame, two locking slots on the inner wall of the canister lid, a sealing block on the outer surface of the bottom end of the canister lid, a bottom plate at the bottom of the smoke generator, a bottom hole in the middle of the bottom surface of the bottom plate, an insert plate at the bottom of the bottom plate, a filter element at the bottom of the insert plate, a base frame at the bottom of the filter element, exhaust ports arranged in a circular array on the bottom surface of the canister body, and a slot on the outer surface of the bottom end of the canister body.

[0006] Preferably, the two card blocks are integrally formed with the can body, the bottom plate is located inside the can body and is integrally formed with the can body, the slot is located at the bottom of the bottom plate, the insert plate is installed into the can body through the slot, and the insert plate is located at the bottom of the bottom hole and abuts against the bottom hole.

[0007] Preferably, the filter element and the base frame are located inside the tank, and the filter element is installed inside the tank via the base frame.

[0008] Preferably, the positions of the two slots on the inner wall of the can lid correspond one-to-one with the positions of the locking blocks, and both locking blocks are installed in the slots. Both slots and the two locking blocks are arc-shaped, and the can lid is engaged with the can body.

[0009] Preferably, the top surface of the can lid is provided by a circumferential array of three exhaust ports and baffles, and the three exhaust ports are arranged in order of small, medium and large. The sealing block at the bottom of the can lid is integrally formed with the can lid.

[0010] Preferably, the can lid is installed on the top surface of the can body by a fixing bracket, and the fixing bracket is threadedly connected to the can body. The position of the rotating groove on the inner wall of the fixing bracket corresponds one-to-one with the position of the sealing block, and the sealing block is installed in the rotating groove.

[0011] Preferably, the smoke generator is installed inside the can body through an inner cover, and the inner cover is bolted to the can body. The bottom end of the lead wire passes through the smoke generator, and the through hole communicates with the exhaust port.

[0012] Beneficial effects

[0013] In this invention, during use, the top of the canister is rotated so that the exhaust port on the top surface of the canister aligns with the through hole of the inner cover. During rotation, one of the large, medium, or small exhaust ports can be aligned with the through hole of the inner cover according to the desired smoke volume, thereby changing the amount of smoke emitted from the smoke-generating canister. The smoke-generating agent inside the canister is indirectly ignited by lighting the fuse, causing it to burn and produce smoke. The emitted smoke is discharged from the canister through the flow channel connecting the through hole and the exhaust port. If it is necessary to change the smoke volume during the smoke emission process, high-temperature protective equipment such as high-temperature resistant gloves must be worn. After wearing these protective gear, the insert plate is pulled out of the slot, allowing the smoke to exit downwards from the bottom hole. Only after the insert plate is pulled out can the top cover be rotated, aligning the exhaust ports of different sizes with the through holes of the inner tube, thus changing the amount of smoke emitted from the smoke-generating canister. This solves the problem of difficulty in adjusting the smoke volume according to actual needs during use. Attached Figure Description

Two locking grooves 5 are provided on the inner wall of the canister cover 2. The bottom end of the canister cover 2... The outer surface is provided with a sealing block 7. The bottom of the smoke generator 10 is provided with a bottom plate 12. A bottom hole 13 is provided in the middle of the bottom surface of the bottom plate 12. An insert plate 15 is provided at the bottom of the bottom plate 12. A filter element 18 is provided at the bottom of the insert plate 15. A base frame 19 is provided at the bottom of the filter element 18. The bottom surface of the tank 1 is provided with an array of exhaust ports 20. The bottom outer surface of the tank 1 is provided with a slot 14. Two locking blocks 6 are integrally formed with the tank 1. The bottom plate 12 is located inside the tank 1 and is integrally formed with the tank 1. The slot 14 is located at the bottom of the bottom plate 12. The insert plate 15 is installed into the tank body 1 through the slot 14, and the insert plate 15 is located at the bottom of the bottom hole 13 and abuts against the bottom hole 13. The filter element 18 and the base frame 19 are located inside the tank body 1, and the filter element 18 is installed inside the tank body 1 through the base frame 19. The positions of the two slots 5 on the inner wall of the tank cover 2 correspond one-to-one with the positions of the locking blocks 6, and both locking blocks 6 are installed in the slots 5. Both slots 5 and locking blocks 6 are arc-shaped. The tank cover 2 is engaged with the tank body 1. Three exhaust ports 3 and baffles 4 are arranged in a circumferential array on the top surface of the tank cover 2. The three exhaust ports 3 are arranged in order of small, medium and large. The sealing block 7 at the bottom of the can lid 2 is integrally formed with the can lid 2. The can lid 2 is installed on the top surface of the can body 1 through the fixing bracket 16, and the fixing bracket 16 is threaded to the can body 1. The position of the rotating groove 17 on the inner wall of the fixing bracket 16 corresponds one-to-one with the position of the sealing block 7, and the sealing block 7 is installed in the rotating groove 17. The smoke generator 10 is installed inside the can body 1 through the inner cover 8, and the inner cover 8 is bolted to the can body 1. The bottom end of the lead wire 11 passes through the smoke generator 10, and the through hole 9 is connected to the exhaust port 3.

[0025] The canister body 1 serves as the main structure, carrying the smoke-generating agent 10 and providing sealing and fixing space for the internal components. Two integrally formed locking blocks 6 are located at the top of the canister body 1. These blocks 6 engage with the arc-shaped grooves 5 on the inner wall of the canister lid 2, ensuring a tight fit during rotation without loosening. The rotational engagement of the locking blocks 6 and grooves 5 allows for position adjustment of the canister lid 2. The top surface of the canister lid 2 has three smoke vents 3 of different sizes, equipped with baffles 4. During rotation, the baffles 4 can either offset or perfectly align with the through holes 9 of the inner lid 8, controlling the flow of smoke release. An integrally formed sealing block 7 at the bottom of the canister lid 2 is installed in a rotating groove 17 on the inner wall of the fixing frame 16. The engagement between the sealing block 7 and the rotating groove 17 ensures a tight seal and prevents leakage during rotation of the canister lid 2, ensuring that smoke can only be discharged from the selected smoke vent 3. The fixing frame 16 and the canister body 1 are connected by threads, ensuring a stable connection between the canister lid 2 and the canister body 1. The bottom plate 12 inside the tank body 1 is integrally formed with the tank body 1. The bottom plate 12 has a bottom hole 13, and the opening and closing of the bottom hole 13 is controlled by an insert plate 15. The insert plate 15 is inserted through a slot 14. When it is pressed against the bottom hole 13, it can block the bottom smoke passage. When the insert plate 15 is pulled out, the bottom hole 13 is opened to form a lower smoke exhaust path. A filter element 18 is set below the insert plate 15. The filter element 18 is fixed on a base frame 19, which is installed at the bottom of the tank body 1. The filter element 18 filters the passing smoke, converting colored smoke into colorless smoke as it passes through, and then evenly discharges it from the bottom exhaust port 20. The function of the filter element 18 is to partially filter colored smoke and convert it into colorless smoke, reducing colored emissions. The base frame 19 provides stable support for the filter element 18 and keeps the passage unobstructed, ensuring smooth smoke filtration and downward exhaust flow. The bottom exhaust ports 20 are distributed in a circumferential array to ensure that the filtered colorless smoke can be released evenly and to avoid excessive internal pressure accumulation. In normal release mode, the operator must first rotate the canister lid 2 to align one of the exhaust ports 3 with the through hole 9 of the inner cover 8, ensuring that the smoke can be smoothly discharged from the exhaust port 3. When rotating the canister lid 2, the sealing block 7 and the rotating groove 17 cooperate to maintain a seal and control the smoke flow direction. At the same time, the locking block 6 rotates in the locking groove 5, playing a role in limiting and sealing. When it is necessary to adjust the smoke discharge size, since the inside of the canister 1 is already at a high temperature, it is necessary to first wear high-temperature resistant gloves, protective clothing and other protective equipment, then pull out the insert plate 15, open the bottom hole 13, so that the smoke can be temporarily discharged from the bottom, filtered by the filter element 18 and released from the bottom exhaust port 20, to avoid danger caused by the upper smoke not being able to be discharged during the rotation of the canister lid 2. After the insert plate 15 is pulled out, the canister lid 2 can be rotated again to reselect the size of the exhaust port 3. After the alignment is completed, the insert plate 15 is inserted into the slot 14 and the bottom hole 13 is sealed, so that the smoke can be discharged from the top again.If it is necessary to block the upper exhaust in special circumstances, the insert plate 15 must be pulled out first to open the bottom flow channel. Then, rotate the can cover 2 to align the baffle 4 area with the through hole 9 of the inner cover 8, thus blocking the through hole 9. At this time, the smoke cannot continue to pass through the upper exhaust port 3, but instead flows down through the bottom hole 13, is filtered by the filter element 18, and is released from the bottom exhaust port 20 as colorless smoke. It should be noted that the baffle 4 does not completely seal the can, and a small amount of smoke is still allowed to escape to prevent the risk of can explosion due to excessive internal pressure. Specific Implementation Example 2:

[0027] Reference Figure 1-5A controllable release smoke generator can is further based on the basic structure in Specific Embodiment 1. In use, the smoke generator 10 inside the canister 1 is first ignited by the ignition fuse 11. The smoke generator 10 produces colored smoke after combustion. The smoke discharge is controlled by the combined action of the canister lid 2, inner lid 8, exhaust port 3, insert plate 15, and filter element 18. The canister 1, as the main structure, carries the smoke generator 10 and provides a sealed space. The top locking block 6 engages with the locking groove 5 on the inner wall of the canister lid 2, ensuring that the canister lid 2 remains tightly fitted to the canister 1 during rotation, preventing loosening or leakage. Simultaneously, the rotation of the locking block 6 within the locking groove 5 also serves as a positioning and sealing aid. The top surface of the canister lid 2 has three smoke vents 3 of different sizes, which can form different correspondences with the through holes 9 of the inner lid 8 during rotation. If the through hole 9 corresponds to the small smoke vent 3, the smoke release is small; if it corresponds to the medium smoke vent 3, the release is medium; and if it corresponds to the large smoke vent 3, the release is maximum. When the canister lid 2 rotates, the baffle 4 can be misaligned or fully aligned with the through hole 9, achieving precise control of the smoke release through this alignment. The sealing block 7, integrally formed at the bottom of the canister lid 2, is embedded in the rotating groove 17 on the inner wall of the fixing frame 16. As the canister lid 2 rotates, the sealing block 7 remains sealed within the rotating groove 17, ensuring that the smoke can only be discharged through the corresponding smoke vent 3 according to the predetermined flow path, preventing leakage. The fixing frame 16 is threadedly connected to the canister body 1, making the canister lid 2 and the canister body 1 firmly connected and preventing loosening due to vibration or airflow impact during the entire adjustment process. When adjusting the smoke output, the operator must wear high-temperature gloves and protective clothing to prevent injury from contact with hot components, as the combustion of the internal smoke-generating agent 10 creates a high-temperature environment. During adjustment, first pull out the insert plate 15 to open the bottom hole 13, allowing the smoke to temporarily exit from the bottom. After being filtered by the filter element 18, the smoke is converted into colorless smoke and evenly released through the exhaust ports 20 in the bottom circumferential array. This prevents the internal pressure from increasing due to obstructed smoke exhaust during the rotation of the canister lid 2, which could be dangerous. After pulling out the insert plate 15, the canister lid 2 can be smoothly rotated to the desired position, realigning the smoke exhaust ports 3 of different sizes with the through holes 9 of the inner cover 8. After adjustment, insert the insert plate 15 back into the slot 14 to seal the bottom hole 13, allowing the smoke to exit from the upper flow channel again. If it is necessary to block the upper smoke exhaust, the insert plate 15 must be pulled out first to open the bottom flow channel. Then, the can lid 2 should be rotated so that the area of ​​the baffle 4 is aligned with the through hole 9 of the inner lid 8, thereby sealing the upper channel and forcing the smoke to descend from the bottom hole 13. After being filtered by the filter element 18, the smoke is released from the bottom exhaust port 20 in the form of colorless smoke. Since a complete seal may cause the can to explode, the baffle 4 is designed to be not completely sealed, allowing a small amount of smoke to escape during the blocking process to ensure safety.

[0028] In summary:

[0029] 1. When using this device, rotate the canister cap 2 on top of the canister 1 to align the exhaust port 3 on the top surface of the canister cap 2 with the through hole 9 of the inner cover 8. During rotation, one of the large, medium, or small exhaust ports 3 can be aligned with the through hole 9 of the inner cover 8 according to the desired smoke output, thereby changing the smoke output of the smoke generator. The smoke-generating agent 10 inside the canister 1 is indirectly ignited by igniting the fuse 11, causing the smoke-generating agent 10 to burn and generate smoke. The emitted smoke is discharged from the canister 1 through the flow channel connecting the through hole 9 and the exhaust port 3. If it is necessary to change the smoke output during the smoke output process, high-temperature protective equipment such as high-temperature resistant gloves must be worn. After wearing these protective gear, pull out the insert plate 15 from the slot 14 to allow the smoke to exit downwards from the bottom hole 13. Only after the insert plate 15 is pulled out can the top cover be rotated to align the exhaust ports 3 of different sizes with the through holes 9 of the inner tube, thereby changing the smoke output of the smoke generator. This solves the problem of difficulty in adjusting the smoke output according to actual needs during use.
