The utility model discloses absorbing device is used in ambient air and waste gas sampling, moreover, the steam generator is simple in structure, high durability and convenient operation, drive cam 16 through No. two drive arrangement 14 of intermittent type sampling mechanism inside on the one hand and make piston piece 19 reciprocate in sleeve pipe 1's inside, thereby conveniently inhale sleeve pipe 1's inside with the air, on the other hand is plugged up exhaust air through preventing leaking the mechanism, make the air along connecting pipe 2 get into in the one-way sampling bottle 9 that admits air, because No. 4 settles of casing have a plurality of one-way sampling bottles 9 that admit air, thereby collect the air of different time quantum collections, thereby the effectual trouble that reduces the sampling, and make the sample of sampling more comprehensive.

Specifically, the inside of intermittent type sampling mechanism is including sleeve pipe 1, sleeve pipe 1's left side outer wall fixed mounting has support frame 13, the inside fixed mounting of support frame 13 has drive arrangement 14 No. two, drive arrangement 14's right side and the inside movable mounting who is located sleeve pipe 1 have pivot 15 No. two, fixed mounting has cam 16 between the adjacent pivot 15 No. two, the inside movable mounting of cam 16 has movable sleeve 17, the top fixed mounting of movable sleeve 17 has connecting rod 18 No. two, the top fixed mounting of connecting rod 18 No. two has piston block 19, the inside of sleeve pipe 1 and the below fixed mounting who is located piston block 19 have fixed plate 20 No. two, the inside of sleeve pipe 1 and the top fixed mounting who is located piston block 19 have baffle 21.

In this embodiment, when the second driving device 14 is driven to make the second rotating shaft 15 drive the cam 16 to perform a rotating motion with the second rotating shaft 15 as an axis, the cam 16 makes the movable sleeve 17 and the second connecting rod 18 drive the piston block 19 to move up and down in the casing 1, and the sampling of the air sample is completed in the process of the up and down movement of the piston block 19.

Specifically, prevent leaking the inside of mechanism including support 10, sleeve pipe 1's top fixed mounting has support 10, adjacent support 10's top fixed mounting has fixed plate 12 No. one, the top fixed mounting of fixed plate 12 has spring 24, the top fixed mounting of spring 24 has limiting plate 23, the bottom fixed mounting of limiting plate 23 has No. three connecting rods 22, and No. three connecting rods 22 extend to sleeve pipe 1's inside, the below fixed mounting that No. three connecting rods 22's bottom just is located baffle 21 has sealed the pad 11.

In this embodiment, when the piston block 19 moves downwards, the spring 24 is compressed by the decrease of the air pressure inside the casing 1, the sealing gasket 11 moves downwards to be separated from the joint state with the baffle 21, so that air can enter the sealing gasket, and the air sampling is completed.

Specifically, the piston block 19 is made of rubber, and the outer wall of the piston block 19 is tightly attached to the inner wall of the casing 1.

In this embodiment, since the outer wall of the piston block 19 is closely attached to the inner wall of the casing 1, the air absorption capacity of the piston block 19 is enhanced when moving up and down, thereby ensuring the effectiveness of the air sampling process.

Specifically, the sealing gasket 11 is made of rubber, and the shape of the top of the sealing gasket 11 is matched with the bottom of the baffle 21.

In this embodiment, when the top shape of the sealing gasket 11 is tightly attached to the bottom of the baffle 21, and the piston block 19 moves upward, the vent hole of the baffle 21 is sealed by the sealing gasket 11, so that the air sample sucked in the casing 1 is squeezed into the one-way air inlet sampling bottle 9 through the connecting tube 2.

Specifically, the sleeve 1 is communicated with the first shell 4 through a connecting pipe 2.
