As shown in fig. 1-5, when the apparatus of the present invention is in the initial state, the primary drive gear 44 is meshed with the drive spur gear 29, the pulley gear 50 is not meshed with the fan drive gear 46, the primary magnetic block 13 corresponds to the secondary magnetic block cavity 26, the limit shaft spring 62 is in the compressed state, and the seal plate spring 16 is in the compressed state;

sequence of mechanical actions of the whole device:

when the electric mosquito killer starts to work, the motor 35 is started to rotate, the motor magnet 40 is driven to rotate by the rotation of the motor 35 through the motor shaft 41, the main transmission gear 44 is driven to rotate by the rotation of the motor magnet 40 through the motor transmission shaft 43, the main transmission gear 44 rotates to drive the transmission straight gear 29 and the fan transmission gear 46 to rotate simultaneously, the fan transmission gear 46 rotates to drive the fan bevel gear 66 to rotate through the fan transmission shaft 47, the fan bevel gear 66 rotates to drive the fan bevel gear shaft 69 to rotate through the fan bevel gear 68, so that the fan blade 70 rotates, the fan blade 70 rotates to suck mosquitoes, the mosquitoes are blown down on the power grid 22 to be killed at high;

the main transmission gear 44 rotates and simultaneously drives the transmission pulley shaft 34 to rotate through the transmission spur gear 29, the transmission pulley shaft 34 rotates and drives the belt 20 to rotate through the transmission pulley 32, the belt 20 rotates and drives the driven pulley shaft 15 to rotate through the driven pulley 19, the driven pulley shaft 15 rotates and drives the detector gear 25 to rotate through the instrument transmission gear 23, the detector gear 25 rotates and drives the gas detector 27 to rotate through the gas detector shaft 28, the gas detector 27 rotates and prevents mosquitoes from falling on the gas detector 27, and therefore the detection effect of the gas detector 27 is affected;

when the gas detector 27 detects that the combustible gas in the mine is close to the combustible concentration, the gas detector 27 sends a signal to enable the electromagnet 37 to be powered on, the motor 35 is started to rotate reversely, the electromagnet 37 electrically adsorbs the motor magnet 40 to move downwards by overcoming the thrust of the motor magnet spring 38, the motor magnet 40 moves downwards to drive the main transmission gear 44 to move downwards through the motor transmission shaft 43 to be disengaged from the transmission spur gear 29, the main transmission gear 44 moves downwards to drive the shifting plate 45 to move downwards, the shifting plate 45 moves downwards to pull the limiting block 75 to move outwards by overcoming the thrust of the limiting block spring 74 through the limiting block pull rope 72, so that the limiting block 75 is not at the limiting sealing plate 14, the sealing plate 14 moves upwards to the sealing air outlet channel 11 under the elastic force of the sealing plate spring 16, the electric spark generated by the power grid 22 and the gas detector 27 is prevented from igniting the combustible gas, and meanwhile, the right sealing plate 14 seals the air outlet channel 11, the air pressure on the left side and the right side of the fan blade 70 is different, so that the fan blade 70 is caused to vibrate, and air molecules around the fan blade are also caused to vibrate to make a sound, so that a worker is reminded to leave the current position as soon as possible;

when the device is departed from the safety position and needs to be reset, the reset shaft 58 is pressed to move downwards to the limit shaft 60 to enter the limit shaft abutting cavity 59 by overcoming the thrust of the reset shaft spring 56 and limit the reset shaft 58 to reset, at the moment, the main magnet 57 corresponds to the auxiliary magnet cavity 63, the main magnet 57 adsorbs the auxiliary magnet 64 to move leftwards, the auxiliary magnet 64 moves leftwards to pull the wire wheel plate 49 to move upwards by overcoming the thrust of the wire wheel plate spring 48 through the auxiliary magnet pull rope 65, the wire wheel plate 49 moves upwards to drive the wire wheel gear 50 to be meshed with the fan transmission gear 46, at the moment, the fan transmission gear 46 rotates to drive the wire wheel shaft 51 to rotate through the wire wheel gear 50, the wire wheel 52 rotates to drive the seal plate 14 to move downwards to reset by overcoming the thrust of the seal plate spring 16 through the seal plate pull rope 18, at the moment, the limit block 75 abuts against the inner wall of the limit, the left main magnetic block 13 corresponds to the auxiliary magnetic block cavity 26, the left main magnetic block 13 adsorbs the auxiliary magnetic block 12 to move leftwards, the auxiliary magnetic block 12 moves leftwards, the limiting shaft 60 is pulled by the limiting shaft pull rope 53 to overcome the thrust of the limiting shaft spring 62 to move rightwards to be separated from the limit shaft abutting cavity 59 to abut, and the reset shaft 58 resets under the elastic action of the reset shaft spring 56.

The invention has the beneficial effects that: this device passes through the flabellum and inhales the mosquito of miner's lamp front end, then eliminate at high pressure through the electric wire netting, avoid the mosquito to influence staff's work efficiency, also reduce the risk of mosquito spread disease simultaneously, then avoid the mosquito to block the detection effect of gaseous detector through rotating gaseous detector, cause the testing result error, thereby cause certain accident, then through the closed air-out passageway of closing plate, make the part that probably produces the electric spark keep apart with the external world, avoid the electric spark to ignite combustible gas, cause the explosion risk, then still can remind the staff to leave the current position through the sound that the flabellum outwards bloies and forms, avoid casualties.
