[0030] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but are not intended to limit the scope of protection of the present invention.
[0031] Example:
[0032] As attached Figures 1 to 8 As shown:
[0033] The present invention provides a fire-fighting smoking machine, comprising an outer shell 101 serving as the main frame of the entire smoking machine, providing a mounting base and protecting internal components. The outer shell 101 is made of a metal material with a certain strength and fire resistance, capable of maintaining structural stability in a fire environment, preventing deformation or damage due to high temperature or external forces, and ensuring normal operation of the internal components of the smoking machine.
[0034] A mounting groove 102 is provided on the top of the outer shell 101, and a smoke removal component is arranged in the mounting groove 102; the smoke removal component is the part that realizes the smoke removal function of the smoking machine, and includes a first rotating drum 201 rotating in the forward direction and a second rotating drum 202 rotating in the reverse direction; the first rotating drum 201 is rotatably arranged in the mounting groove 102, and the second rotating drum 202 is rotatably arranged in the first rotating drum 201, and a rotating motor 203 is arranged on both sides of the outer shell 101. The two groups of rotating motors 203 are respectively connected to the first rotating drum 201 and the second rotating drum 202. By transmitting the power of the two groups of rotating motors 203 to the first rotating drum 201 and the second rotating drum 202 respectively, the first rotating drum 201 and the second rotating drum 202 are rotated in opposite directions. Through the arrangement of the smoke removal component, the smoking machine does not require a dedicated smoke exhaust channel, which solves the problem that traditional smoke exhaust machines rely on dedicated smoke exhaust channels. In actual applications, traditional smoke exhaust fans require the construction of a complex smoke exhaust duct system in the building, while this smoke exhaust fan processes the smoke particles through the internal first rotating drum 201 and the second rotating drum 202, and directly discharges the air after the smoke is removed, avoiding the construction of the smoke exhaust channel, saving a lot of manpower and material resources, and reducing the overall construction cost of the building.
[0035] An air inlet slot 103 connected to the mounting slot 102 is provided at one end of the outer shell 101. An air inlet assembly is provided in the air inlet slot 103 to ensure that air can smoothly enter the mounting slot 102 from the outside. A smoke detector is provided on the top of the outer shell 101. When the smoke detector detects smoke, the air inlet assembly and the smoke removal assembly are activated.
[0036] Please refer to Figure 3 and Figure 4As shown, a through hole is formed at one end of the first rotating drum 201. A bearing 204 is disposed at one end of the through hole, and a mounting seat 205 is disposed outside the bearing 204. A first connecting shaft 206 is disposed at one end of the second rotating drum 202. The first connecting shaft 206 passes through the through hole and the bearing 204 and is connected to the main shaft of one of the rotating motors 203. This reduces friction during the rotation of the first connecting shaft 206 and ensures smooth rotation of the second rotating drum 202. The mounting seat 205 is fixed to the through hole of the first rotating drum 201, providing stable mounting support for the bearing 204. A diamond-shaped nanomaterial grid is arranged on the first and second rotating drums 201, 202. Driven by the two rotating motors 203, the first and second rotating drums 201, 202 rotate at high speeds in opposite directions. When smoke enters the smoke-breaking chamber 305, the high-speed rotation of the first and second rotating drums 201, 202 shatters the smoke particles, removing the smoke and achieving the desired smoking effect.
[0037] Please refer to Figure 4 As shown, a rotating ring 207 is provided at the other end of the first rotating drum 201, and two groups of rotating seats 208 are provided on the inner wall of one side of the mounting groove 102. A rotatable rotating wheel 209 is provided at one end of the two groups of rotating seats 208. The two groups of rotating wheels 209 are in rotatable contact with the rotating ring 207. The rotating ring 207 and the first rotating drum 201 are an integrally formed structure, which can ensure strength and stability during the rotation process; the rotating seat 208 is fixedly mounted on the inner wall of the mounting groove 102, and a bearing is provided inside it for supporting the rotating shaft of the rotating wheel 209 so that the rotating wheel 209 can rotate flexibly; the two groups of rotating wheels 209 are in rotatable contact with the rotating ring 207. When the first rotating drum 201 rotates, the rotating wheel 209 can rotate smoothly following the rotating ring 207, providing stable support for the first rotating drum 201, reducing its radial runout during rotation, and improving stability.
[0038] Please refer to Figure 4 As shown, two groups of connecting seats 210 are provided on one side of the rotating ring 207, and a connecting rod 211 is provided between the two groups of connecting seats 210. A second connecting shaft 212 is provided on one side of the connecting rod 211, and the main shaft of another group of rotating motors 203 is connected to the second connecting shaft 212; the connecting seat 210 is installed on one side of the rotating ring 207 by screws, and the two ends of the connecting rod 211 are respectively connected to the connecting seat 210 by welding; the second connecting shaft 212 and the connecting rod 211 are an integral structure, which is connected to the main shaft of the rotating motor 203 through a coupling to ensure that the power of the rotating motor 203 can be effectively transmitted to the first rotating drum 201, so that the first rotating drum 201 rotates.
[0039] Please refer to Figure 2 and Figure 5As shown, the air intake assembly includes an air intake fan 301, an air intake fan 301 is arranged in the air intake slot 103, an air suction cover 302 is arranged on one side of the air intake slot 103 corresponding to the air intake fan 301, and a debris interception net 303 is arranged in the air suction cover 302; the air intake fan 301 is installed in the air intake slot 103, and is fixedly connected to the inner wall of the air intake slot 103 through a bracket, so as to generate sufficient airflow to suck the outside air into the air intake slot 103; through the setting of the air suction cover 302, the air can be guided to flow smoothly to the air intake fan 301, thereby improving the air intake efficiency; the debris interception net 303 is made of metal wire mesh, which can effectively block large particles of debris from entering the interior of the smoking machine, protect the smoke removal assembly, prevent debris from damaging the first drum 201 and the second drum 202, and improve the stability of the operation of the smoking machine.
[0040] Please refer to Figure 6 and Figure 8 As shown, the air intake assembly also includes two groups of air guide covers 304. Two groups of air guide covers 304 are arranged in the installation groove 102. A smoke crushing chamber 305 is formed between the two groups of air guide covers 304. The first rotor 201 and the second rotor 202 are both located in the smoke crushing chamber 305. Through the arrangement of the two groups of air guide covers 304, the air sucked in by the air intake fan 301 can be guided into the smoke crushing chamber 305, so that the air carrying the smoke passes through the first rotor 201 and the second rotor 202 evenly. Through the forward rotating first rotor 201 and the reverse rotating second rotor 202, when the smoke enters the smoke crushing chamber 305, the smoke particles are crushed by the high-speed rotating first rotor 201 and the second rotor 202 in reverse directions, and finally the air without smoke particles is discharged, reducing the impact on the air quality in the surrounding area. A first air guide duct 306 is provided on the other side of the air inlet slot 103 . One side of the first air guide duct 306 is connected to the two sets of air guide covers 304 to stably transport the air in the air inlet slot 103 to the smoke fragmentation chamber 305 .
[0041] Please refer to Figure 8 As shown, the other side of the two groups of air guide covers 304 is connected to a second air guide duct 307, and a through slot is provided at one end of the outer shell 101 away from the air inlet slot 103, and a door frame 308 is provided in the through slot, and a detachable air outlet plate 309 is provided in the door frame 308, and two groups of air outlet ports 310 are provided on the air outlet plate 309; the second air guide duct 307 is used to guide the purified air from the smoke crushing chamber 305 to the air outlet plate 309; the door frame 308 and the outer shell 101 are an integrally formed structure, providing a mounting frame for the air outlet plate 309, and the air outlet plate 309 is connected to the door frame 308 by bolts. This detachable setting facilitates the cleaning and maintenance of the air outlet plate 309. At the same time, the setting of the two groups of air outlet ports 310 ensures that the purified air can be evenly discharged from the smoking hood.
[0042] Please refer to Figure 2 and Figure 8 As shown, a cover plate 104 is connected to the top of the mounting slot 102 by a hinge, and a handle 105 is provided on the top of the cover plate 104 to facilitate the operator to open and close the cover plate 104, and to facilitate the inspection, cleaning and maintenance of the smoke removal assembly; a plurality of sets of universal wheels 106 are provided at the bottom of the outer shell 101, so that the smoke removal machine can be flexibly moved, and can quickly adjust its position according to the actual situation at the fire scene, so as to deal with the smoke in different areas in time.
[0043] The specific usage and function of this embodiment: When the smoke extractor is used in an actual fire-fighting scenario, first, since multiple sets of universal wheels 106 are provided at the bottom of the outer shell 101, the operator can easily push the smoke extractor and move it to a suitable position according to the smoke distribution at the fire scene. Then, the operator uses the brake device of the universal wheel 106 to lock it so that the smoke extractor is stably parked to avoid displacement during operation; when the smoke detector on the top of the outer shell 101 detects smoke, the air intake component and the smoke removal component are started.
[0044] The air intake fan 301 in the air intake assembly is fixed in the air intake slot 103 by a bracket. After being started, it generates airflow. Under the action of the airflow, the outside air is sucked into the air intake slot 103 through the air suction cover 302 on one side of the air intake slot 103. The air suction cover 302 can guide the air well, so that the air flows more smoothly to the air intake fan 301, effectively improving the air intake efficiency; at the same time, the debris interception net 303 in the air suction cover 302 can block large particles of debris such as wood chips and plastic fragments produced by combustion from entering the interior of the smoker, preventing these debris from damaging the subsequent smoke removal components and ensuring the stability of the operation of the smoker.
[0045] The air sucked into the air inlet slot 103 is stably transported to the smoke-breaking chamber 305 formed between the two sets of air guide covers 304 in the installation slot 102 through the first air guide duct 306; in the smoke-breaking chamber 305, the first rotating drum 201 and the second rotating drum 202 of the smoke removal assembly are driven by the rotating motor 203 on both sides of the outer shell 101 to rotate forward and reverse at high speed respectively. Under the action of the high-speed rotating first rotating drum 201 and the second rotating drum 202, the smoke particles are broken into tiny particles, thereby removing the smoke in the inhaled air.
[0046] The air without smoke passes through the second air guide duct 307 and is guided to the slot at one end of the outer shell 101 away from the air inlet slot 103. The door frame 308 in the slot is integrally formed with the outer shell 101, providing a mounting frame for a detachable air outlet plate 309. The air outlet plate 309 is fixed in the door frame 308 by bolts. The two sets of air outlets 310 on its surface can make the purified air evenly discharged from the smoking hood, effectively reducing the impact on the air quality in the surrounding area.
[0047] During the operation of the smoking machine, if the smoke removal assembly needs to be inspected, cleaned or maintained, the operator can pull the handle 105 on the top of the cover 104 and use the hinge structure on the top of the installation slot 102 to open the cover 104, thereby conveniently accessing the various components of the smoke removal assembly and performing corresponding operations to ensure that the smoking machine always maintains good working performance.
