Multidirectional sampling: when the air pump is used for pumping, the second piston plate 12 in the buffer housing 9 moves to one side close to the buffer air outlet pipe 15, the buffer spring 17 is compressed, air outside the automobile enters into the top space of the second piston plate 12 from the buffer air inlet pipe 20, the valve structure is in a closed state, the second piston plate 12 continues to move downwards, the top space gas is continuously increased until the lower ejector rod 16 abuts against the valve structure, the valve structure is opened, the gas in the top space of the second piston plate 12 can finally enter into the air detection instrument for detection through the first plate hole 26, the buffer air outlet pipe 15 and the air pump, the gas in different positions of the automobile is pumped by the two buffer housings 9, and the gas is simply fused in the air pump to enter into the air detector, so that the quality result of the discharged air can be better reflected, and the problem of overlarge detection result error caused by single detection data is avoided.

the first piston plate 10 is elastically connected with the collar 25 by a return spring 27.
It should be noted that, the return spring 27 is used to urge the adduction port 28 to seal with the first piston plate 10, specifically, when the upper push rod 18 is not in contact with the lower push rod 16, the first piston plate 10 seals with the adduction port 28, and gas cannot enter from above the second piston plate 12 to below, and as the second piston plate 12 continues to move downward, the upper push rod 18 and the lower push rod 16 collide, so that the upper push rod 18 and the first piston plate 10 move upward, and urge the first piston plate 10 to unseal the adduction port 28, and at this time, gas can enter from above the second piston plate 12 to below.

Example 2
In this embodiment, as is clear from the above embodiment, when a gap exists between the first piston plate 10 and the adduction port 28, although air enters from above to below the second piston plate 12 at this moment, the buffer spring 17 resets and forces the second piston plate 12 to move upwards due to the increase of the air pressure below the second piston plate 12, so that the upper ejector rod 18 no longer collides with the lower ejector rod 16, and the valve structure is closed instantaneously, which affects the conveying efficiency of air pumping to the air detector, therefore, this embodiment proposes a solution that a third piston plate 21 is further mounted on the first piston plate 10, the third piston plate 21 is slidably mounted in the piston cylinder 11, a limit slider 35 is mounted on the third piston plate 21, a block tooth 36 is further mounted on the limit slider 35, a second plate hole 34 is further opened on the third piston plate 21 for guiding air.

When the upper push rod 18 contacts with the lower push rod 16 and moves upwards, the third piston plate 21 moves upwards, the limit sliding block 35 slides upwards in the limit sliding groove 29, the block tooth 36 can abut against the second tooth surface 33 on the plate tooth 31, the second tooth surface 33 is obliquely arranged, the two elastic plates 30 move away from each other under the action of the abutting force, so that the third piston plate 21 can move upwards smoothly, if the third piston plate 21 has a downward movement trend relative to the elastic plates 30, the block tooth 36 can abut against the first tooth surface 32 on the plate tooth 31, the first tooth surface 32 is horizontally arranged, the block tooth 36 can be carried on the first tooth surface 32, and the two elastic plates 30 cannot be caused to move away from each other, so that the third piston plate 21 cannot move downwards relative to the elastic plates 30 until the second piston plate is continuously reset upwards, the elastic plates 30 abut against the abutting inclined surfaces 23 of the abutting blocks 22, the inclined surfaces 23 urge the two elastic plates 30 to move away from each other, and the third piston plate 21 can move downwards; therefore, the air pump can pump the gas into the air detector more smoothly.
Example 3
This embodiment is a further modification of embodiment 2, and based on embodiment 2, in combination with fig. 6, further includes a gas mixing unit 3, where the gas mixing unit 3 includes a main mixing bin 48;

In this embodiment, the mixing guide tube 43 is connected to different cache air outlet tubes 15, so that the air entering the main mixing bin 48 through the mixing guide tube 43 can blow the rotation of the fan blades 41, and the fan blades 41 can play a certain role in mixing the air to a certain extent when rotating, thereby promoting the uniform mixing of the air and improving the accuracy of detecting the air by the air detector.
Further, a supporting block 13 is also installed in the buffer housing 9 through a spring piece 14.
The elastic sheet 14 can be adaptively deformed when the supporting block 13 is pressed, the supporting block 13 is matched with the elastic sheet 14, when the second piston plate 12 moves downwards, the second piston plate 12 can be contacted with the supporting block 13 first before the upper ejector rod 18 is contacted with the lower ejector rod 16, so that the upper ejector rod 18 can be abutted against the lower ejector rod 16 only when enough negative pressure exists in the space at the bottom of the second piston plate 12, and when the valve structure is opened, gas can be blown to the fan blades 41 more rapidly through the mixing guide pipe 43, and the fan blades 41 can be rapidly rotated by stirring of strong air flow, so that the efficiency of mixed gas is improved.
Further, a guiding arc plate 42 is fixedly installed in the main mixing chamber 48, and the guiding arc plate 42 is used for blocking the gas in the mixing guiding pipe 43 from flowing to the gas mixture outlet pipe 44.
By providing the arc deflector 42, when the gas enters the main mixing bin 48 from the mixing guide pipe 43, the arc deflector 42 can guide the gas to move upwards and be further mixed with the gas just entering the mixing guide pipe 43, so that the mixing effect is improved.
