8. The method and apparatus for detecting the atmospheric quality according to claim 7, wherein: both ends of the crankshaft (33) are rotatably connected with the inner wall of the mounting frame (2) by using bearings, and the two sleeves (34) are made of aluminum alloy materials.
9. The method and apparatus for detecting the atmospheric quality according to claim 7, wherein: the front ends of the two sliding rods (36) are fixedly connected with the backs of the two mounting plates (4), the lengths of the two sliding rods (36) are equal, the outer walls of the two sliding rods (36) are in sliding connection with the mounting frame (2), and the two sliding rods (36) form a reciprocating movement structure through the two limiting rods (35) and the crankshaft (33).
10. The method for detecting the atmospheric quality is characterized by comprising the following steps of:
s1: firstly, a user needs to place the bottom plate (1) at a place to be detected, and the user needs to start the negative pressure machine (5) to work under negative pressure in sequence before detection.
S2: then a user starts the reciprocating motor (32), the reciprocating motor (32) can control the crankshaft (33) to rotate in the mounting frame (2), the rotation of the crankshaft (33) can drive the sleeve (34) to rotate so as to control the limiting rod (35) to drive the sliding rods (36) to slide in the mounting frame (2), and thus the two sliding rods (36) can reciprocate intermittently in tandem under the influence of the crankshaft (33), and thus intermittent collection of gas in the environment can be performed.
S2: then, a first catching plate (84) and a second catching plate (85) are sequentially inserted into the two limit grooves (83), so that the first catching plate (84) and the second catching plate (85) are exposed on the two notches (82).
S3: the negative pressure machine (5) can suck the air in the atmosphere from the air outlet frame (7) to the first catching plate (84) and then pass through the second catching plate (85), so that the impurities in the atmosphere can be captured and collected in two stages, and the negative pressure machine is used for detecting the quality of the atmosphere.
S4: finally, the lifting motor (62) is started to drive the first rotating rod (63) to rotate, the rotation of the first rotating rod (63) can control the first belt pulley (64) to rotate, the rotation of the first belt pulley (64) can control the belt (67) to drive the second belt pulley (66) and the second rotating rod (65) to rotate, the belt (67) can drive the installation component (8) at the bottom to move upwards in the driving process, the installation component (8) at the top moves downwards under the influence of the installation component (8) at the bottom, and therefore the first catch plate (84) and the second catch plate (85) after collection can be taken, and the new first catch plate (84) and the new second catch plate (85) can be replaced in time.
