The working principle is as follows: the first water tank 22 and the second water tank 47 are filled with water, a worker places fingers in the pressing groove 20, pushes the rotary disc 19 to move in the bracelet 10, so that the air collection chamber 14 magnetically adsorbed on the magnetic block 21 of the air chamber is driven to rotate, the air collection chamber 14 pushes the elastic plate 31 to move upwards to overcome the elastic force of the third spring 32, after the elastic plate 31 is crossed, the air collection chamber 14 is prevented from sliding backwards due to the inclined position of the elastic plate 31, meanwhile, due to the fact that the end surface of the drain pipe 29 and the upper surface of the air collection chamber 14 are respectively provided with the second annular magnet 60 and the first annular magnet 40 which are fixedly connected, when the fact that the air collection chamber 14 passes the elastic plate 31 and is adsorbed on the drain pipe 29 is sensed, a sampler presses the pressing block 12 into the working chamber 11, due to the fixed connection of the pressing block 12 and the threaded pressing rod 13, the threaded pressing rod 13 and the piston 23 are fixedly connected, so that the piston 23 moves inwards against the tensile force of the first spring 26, the pressure of the water in the first water tank 22 is increased, thereby opening the first pressure valve 30 in the drain pipe 29, the water flows downwards through the drain pipe 29, at the same time, due to the adsorption of the first ring magnet 40 and the second ring magnet 60, the two water-stopping sliders 44 are squeezed against each other, thereby overcoming the elasticity of the slider spring 45 and squeezing into the water-stopping chute 43, the water flow is communicated through the second water channel 42 and the first water channel 46, so that the water in the first water tank 22 enters into the water bag 39 through the drain pipe 29, at the same time, when the piston 23 moves inwards, the air pressure of the first water tank 22 at the first spring 26 is reduced, the air enters into the first water tank 22 through the air inlet pipe 24 and the first check valve 25, at this time, due to the inward movement of the screw pressing rod 13, the pulling rope 35 fixedly connected to the screw pressing rod 13 also moves inwards and is loosened, so that the second spring 34 is not compressed, the second spring 34 presses the lower end of the exhaust pipe 27 down onto the rotating plate 37, overcoming the force of the torsion spring at the rotating plate 37, the air enters the air collection chamber 14, when the threaded compression rod 13 moves inwards, due to the threaded connection between the threaded wheel 54 and the threaded compression rod 13, the threaded wheel 54 rotates, due to the fact that the threaded wheel 54 is fixedly connected to the first rotating shaft 52, the first rotating shaft 52 is rotatably connected to the working chamber 11, the threaded wheel 54 drives the first belt pulley 53 fixedly connected to the first rotating shaft 52 to rotate, due to the belt transmission between the first belt pulley 53 and the second belt pulley 57, the second belt pulley 57 rotates, due to the fact that the second rotating shaft 55 is rotatably connected to the belt pulley groove 58 and the turbine groove 59, the second rotating shaft 55 is driven by the second belt pulley 57, and due to the fact that the turbine 56 is fixedly connected to the second rotating shaft 55, the turbine 56 rotates to assist air suction of the air inlet pipe 24, and further air flow entering is accelerated; during the inward movement of the piston 23, the liquid in the first water tank 22 is injected into the water bag 39 in the air collection chamber 14 through the drain pipe 29, and simultaneously the air in the air collection chamber 14 is discharged through the second pressure valve 36, and the gas cannot be discharged upwards through the exhaust pipe 27 due to the second check valve 28 arranged in the exhaust pipe 27;

after the extrusion is finished, the piston 23 is returned by the pulling force of the first spring 26, the threaded compression rod 13 and the pressing block 12 are pushed to reset, at the moment, the liquid in the water bag 39 is sucked into the first water tank 22 again, meanwhile, the gas at the position of the first spring 26 can only downwards enter the gas collection chamber 14 through the exhaust pipe 27 due to the fact that the first one-way valve 25 is arranged at the position of the air inlet pipe 24, the change of the internal air pressure is small due to the fact that air enters from the water outlet side of one side in the gas collection chamber 14, the first pressure valve 30 is in a closed state, meanwhile, when the liquid in the water bag 39 is completely sucked, the threaded compression rod 13 continuously moves outwards, the pull rope 35 is pulled out, the tail end of the exhaust pipe 27 is pulled to be separated from the gas collection chamber 14, the rotating plate 37 is reset by the torsion spring after being not subjected to the pressure of the torsion exhaust pipe 27, and the gas is stored in the gas collection chamber 14;

meanwhile, in the process of ejecting the threaded compression rod 13, the threaded wheel 54 rotates reversely to drive other parts to rotate reversely, so that the turbine 56 rotates reversely, the dust adsorbed when air is introduced from the turbine 56 is stirred out, and the rotating disc 19 is repeatedly moved by fingers to rotate the next air collecting chamber 14 to the lower part of the working chamber 11 to sample the air;

when sampling in the air that has harm, keep the bracelet level, it can be higher than the surface of water to keep the play trachea 50 in the second water tank 47, it stretches into the state of aquatic to go into trachea 48, open gas hood board 51, make gas hood 18 pop out from gas hood room 16, the personnel of sampling covers gas hood room 16 in the oral-nasal department, it breathes in through play trachea 50 that gas hood 18 department is connected, the external gas carries out the prefilter through the filter block 49 that goes into trachea 48 department, it produces suction and makes the atmospheric pressure reduction in the second water tank 47 to go out trachea 50 other end, thereby make external gas filter after getting into second water tank 47 surface of water below through going into trachea 48 and float out, be inhaled the human body through going out trachea 50, take out plenum chamber 14 and detect a plurality of gas samples through dismantling lower carousel 19 from bracelet 10 at last.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent processes performed by the present invention or directly or indirectly applied to other related technical fields are also included in the scope of the present invention.
