when the air guide cylinder works, in the initial stage of fire, under the condition that the smoke concentration is low, low-concentration smoke can enter the protective cover 5 through the through hole of the protective cover 5, the second motor 12 is started, the second motor 12 can drive the first transmission rod 13 to rotate, the first transmission rod 13 can further drive the first gear 14 to rotate, the first gear 14 drives the second gear 16 and the second transmission rod 15 to rotate in a meshing mode, the second gear 16 can drive the connecting block 17 to rotate, the connecting block 17 further drives the power rod 18 to revolve along the axis of the second transmission rod 15, the power rod 18 can drive the guide rod 19 to move, the piston 2 is further driven to move up and down in the cylinder groove through the guide rod 19, the pressure reduction and pressurization of the air pressure in the cylinder groove are alternately carried out, when the air pressure in the cylinder groove is low, external air can be unidirectionally guided into the air guide cylinder groove through the check valve 10 in the sealing plate 7, when the piston 2 moves downwards and pressurizes the inside of the cylinder groove, the gas with low-concentration smoke is compressed, so that the smoke concentration in the gas is increased, the pressurized gas can directly enter the inside of the smoke sensor 20, and the smoke sensor 20 can effectively detect the smoke and give an alarm to realize automatic water spraying, fire extinguishing and temperature reduction of the spray head 3 due to the fact that the pressurized gas is reduced in volume and the smoke concentration in the inside is increased; the first guide hole 21 is formed in the surface of the sealing plate 7, the second guide hole 22 is formed in the surface of the rotating block 8, when the first motor 9 rotates, the rotating block 8 can be driven by the first motor 9 to rotate, automatic connection and automatic disconnection between the second guide hole 22 and the corresponding first guide hole 21 are achieved through rotation of the rotating block 8, automatic connection and complete isolation between the cylinder groove and the external environment are achieved, and when the interior of the cylinder groove is pressurized, long-time reverse compression of air pressure on the check valve 10 in the pressurizing process is avoided through isolation switching, and the service life of the check valve 10 is influenced; by arranging the rotating plate 24, the piston 2 can drive the fixed block 23 on the lower surface of the piston 2 to move up and down through the up-and-down movement of the piston 2, the rotating plate 24 can be driven to move up and down through the fixed block 23, the rotating plate 24 and the inner surface of the rotating block 8 are in threaded connection, the rotating plate 24 can rotate while moving up and down, the rotating plate 24 can drive the fan blades 25 uniformly arranged below the rotating plate to rotate, the disturbance of the internal gas of the cylinder groove is realized through the fan blades 25, and the smoke particle precipitation of the internal gas of the cylinder groove is avoided when the internal gas of the cylinder groove is pressurized, so that the smoke detection is influenced; through the arrangement of the bottom plate 26 and the cleaning plate 30, the rotating plate 24 can drive the guide block 27 to rotate through the rotation of the rotating plate 24, the guide ring 28 can further drive the guide ring 28 to rotate, the cleaning plate 30 on the lower surface of the guide ring 28 can be driven to rotate through the guide ring 28, the guide ring 28 is automatically adjusted up and down through the arrangement of the first spring 29, and meanwhile, the dust particles falling into the upper surface of the bottom plate 26 are automatically cleaned through the rotation of the cleaning plate 30; by arranging the first water guide hole 31 and the second water guide hole 32, when the rotating block 8 rotates, automatic conduction and staggered closing between the first water guide hole 31 and the second water guide hole 32 are realized, when the first water guide hole 31 and the second water guide hole 32 are conducted, water can be introduced into the cylinder groove and continuously led out, the inner surface of the cylinder groove is cleaned, and the influence of internal attached smoke dust on subsequent detection is reduced; by arranging the upper surface of the bottom plate 26 to be an inclined structure with a left bottom and a right top, when water passes through the air cylinder groove and cleans the interior of the air cylinder groove, the inclined structure can play a role in guiding water, so that the water is promoted to rapidly flow out through the air cylinder groove, and meanwhile, the phenomenon that a large amount of water is accumulated in the air cylinder groove and cannot be effectively guided out, and the air pressure regulation in the air cylinder groove is influenced is avoided; by making the hole width of the left second water guide hole 32 smaller than that of the right second water guide hole 32, when the right second water guide hole 32 is communicated with the corresponding first water guide hole 31, the left second water guide hole 32 is not communicated with the corresponding first water guide hole 31, water can be continuously introduced into the cylinder groove and accumulated in the cylinder groove, when a large amount of water is accumulated in the cylinder groove and the interior of the cylinder groove is fully cleaned, the left second water guide hole 32 and the first water guide hole 31 are opened, water flows out quickly, and the interior of the cylinder groove is fully flushed; through setting up the floater 40, when the inside water accumulation of cylinder groove is more, water can not cross smoke transducer 20, avoid water direct inflow smoke alarm's inside, cause smoke alarm's damage problem, under the buoyancy of water effect, floater 40 can float automatically, floater 40 can drive connecting rod 39 upward movement, connecting rod 39 and then drive air guide plate 36 upward movement, can drive the jam 37 motion of its upper surface through air guide plate 36, realize the automatic shutoff to smoke transducer 20's open-ended, the water level is moved back down, can open again smoke transducer 20's opening, smoke transducer 20 can normal work.
