As shown in fig. 2 to 11, when the air holes 242 clean the aperture of the protection net of the smoke alarm, the air holes 242 cannot be cleaned when the protection net of the smoke alarm needs to be cleaned comprehensively because the positions of the air holes 242 are fixed. The inner ring of the gas ring 24 is provided with a rotatable rotating ring 241, a gas injection hole 242 of the rotatable rotating ring 241 is arranged on the surface of the rotating ring 241, a crown gear II 244 is arranged on the bottom surface of an inner cavity of the rotating ring 241, a support II 243 is arranged in a vent hole 235 of the rotatable rotating ring, a rotatable rotating shaft II 8 is coaxially arranged through the support II 243, a belt pulley III 83 is arranged at the end part of the rotating shaft II 8 positioned in the gas pipe 23, a blade II 82 capable of accelerating gas discharge is arranged at the end part of the other side of the rotating shaft II 8, and a gear III 81 capable of driving the crown gear II 244 to rotate is fixedly arranged outside the blade II 82.
Meanwhile, a belt pulley IV 232 on the same side as the belt pulley III 83 is arranged on the inner wall of the air pipe 23, a belt II 84 is sleeved between the belt pulley IV 232 and the belt pulley III 83, a limit post 234 is arranged on one side of the top of the air pipe 23 in a downward extending mode, a rack II 9 capable of moving in a telescopic mode is sleeved on the outer peripheral face of the limit post 234, a spring II 91 is arranged between the bottom face of the inner portion of the rack II 9 and the bottom of the limit post 234, and meanwhile the bottom of the rack II 9 extends to the bottom of the inner cavity of the compression cavity 211. Therefore, when the fume hood 21 moves upwards, the bottom of the inner cavity of the compressing cavity 211 is abutted against the bottom of the rack two 9, so that the rack two 9 can move upwards, then the rack two 9 can be meshed with the gear four 233 to drive the gear four 233 to rotate, the gear three 81 can rotate after the gear four 233 rotates and sequentially pass through the belt pulley four 232, the belt two 84 and the belt pulley three 83, then the gear three 81 drives the rotating ring 241 to enable the air injection holes 242 to clean holes of the protective net, and when the gear three 81 rotates, the air can be further accelerated to be discharged through the blade two 82, so that the cleaning effect is improved.
Specifically, this fire-fighting equipment detection device's theory of operation: when the smoke alarm needs to be detected, the top ring 22 can be covered on the outer side of the smoke alarm at the moment, then the smoke generating cover 21 is pushed upwards, because the space inside the compression cavity 211 is continuously compressed by the bottom plate 231, gas inside the compression cavity can be sprayed out through the gas pipe 23 and the gas spraying holes 242, and because the gas spraying holes 242 correspond to the protective net cover of the smoke alarm, the gas with pressure sprayed out from the gas spraying holes 242 can play a certain hole cleaning effect on the protected holes, so that smoke can enter the detection conveniently.
With the continuous upward pushing of the fume hood 21, the ejector rod 222 touches two sides of the upper end of the turning plate 6, the turning plate 6 can be turned over and opened under the pushing, meanwhile, when the turning plate 6 turns over, the turning plate 6 can synchronously drive the belt pulley two 63 through the belt pulley two 61 and the belt one 62, the crown gear one 52 can rotate through the gear two 64 after the belt pulley two 63 rotates, the through hole two 53 penetrating the upper surface of the rotating plate 5 and the through hole one 214 can vertically opposite after the crown gear one 52 rotates, then the gas ring 24 is retracted into the compression cavity 211, the gas injection holes 242 can be blocked through the inner wall of the compression cavity 211, and further when the bottom plate 231 continuously extrudes gas in the compression cavity 211, the extruded gas can reversely enter the smoke cavity 216 through the through hole one 214, the through hole two 53 and the rotating groove 217, so that the smoke emitted by the electronic smoke generating component 4 can be accelerated to float to the smoke sensing alarm for fire protection detection.
When the smoke generating cover 21 moves upwards, the first rack 221 can rotate the first gear 72, the first spring 73 can be twisted and compressed through the first rotating shaft 71 after the first gear 72 rotates, meanwhile, as the first rack 221 has limited rack length, the first rack 221 and the first gear 72 are not meshed for transmission after the air spraying hole 242 enters the compression cavity 211, and then the first spring 73 can exert force, so that the first blade 74 can rotate, and further smoke in the smoke generating cavity 216 can be accelerated to be discharged.
Meanwhile, the bottom of the inner cavity of the compression cavity 211 is abutted against the bottom of the rack II 9, so that the rack II 9 moves upwards, then the rack II 9 can be meshed with the gear IV 233 to drive the gear IV 233 to rotate, the gear IV 233 can rotate, the gear III 81 can rotate through the belt pulley IV 232, the belt II 84 and the belt pulley III 83 in sequence after rotating, then the gear III 81 drives the rotating ring 241 to enable the air injection holes 242 to clean holes of the protective net in a rotating mode, and when the gear III 81 rotates, the air can be discharged through the blade II 82 to be further accelerated, so that the cleaning effect is improved.
It should be noted that, the specific model specification of the electronic smoke generating component 4 needs to be determined by selecting a model according to the actual specification of the device, and the specific model selection calculation method adopts the prior art in the field, so the detailed description is omitted.
The power supply of the electronic smoking assembly 4 and its principles will be apparent to those skilled in the art and will not be described in detail herein.
