A baffle 17 is installed on the front of the sampling body 1. The oval shell 8 can provide support for the activities of the long spring 9 and the round block 10 under the fixed support of the sampling body 1. The baffle 17 can block the movement of the movable plate 15 under the action of external force under the fixed support of the sampling body 1. The staff pulls the pull ring 16 in the protection component, so that the pull ring 16 can drive the movable plate 15 to move under the action of external force, so that the movable plate 15 can move along the inside of the bottom shell 13. At the same time, the staff moves the bottom shell 13 downward, so that the bottom shell 13 can drive the outer cover 12 to move downward under the action of external force, so that the outer cover 12 can drive the round block 10 to move downward through the connecting rod 11 under the action of external force, so that the round block 10 can move downward along the inside of the oval shell 8. When the connecting rod 11 moves to the bottom of the opening of the oval shell 8, the staff releases the pull ring 16, so that the short spring 14 can use its own elastic force to drive the movable plate 15 out of the inside of the bottom shell 13, so that the movable plate 15 can move to the bottom of the baffle 17. The staff then releases the bottom shell 13, so that the long spring 9 can use its own elastic force to drive the movable plate 15 to move upward through the round block 10, the connecting rod 11, the outer cover 12 and the bottom shell 13, so that the movable plate 15 can contact and be fixed with the baffle 17, so that the outer cover 12 can block the front of the sampling body 1, so that the protection component can protect the control panel of the sampling body 1, and thus can reduce the damage probability of the sampling body.

[0030] Please refer to Figure 1 、 Figure 2 and Figure 3 , an air particulate matter sampler;

[0031] When the staff needs to open the protection component to use the sampling body 1, the staff pulls the pull ring 16, so that the movable plate 15 moves away from the bottom of the baffle 17, so that the long spring 9 can drive the outer cover 12 and the components associated with the outer cover 12 to move upward together, so that the outer cover 12 is opened, and the staff then releases the pull ring 16.

[0032] Please refer toFigure 1 , Figure 4 and Figure 5 , an air particulate sampler;

[0033] It includes a sampling head 5. A support assembly is installed outside the sampling head 5, and the support assembly is located at the top of the sampling main body 1.

A threaded sleeve 25 is installed outside the locking block 24, and the threaded sleeve 25 is threadedly connected to the threaded column 23. The locking block 24 can provide support for the threaded sleeve 25 under the fixed support of the sampling main body 1. When the staff installs the sampling head 5, by rotating the sampling head 5, the positions of the four threaded columns 23 are adjusted so that the threaded columns 23 can move to positions corresponding to the threaded sleeves 25. The staff sequentially screws the four threaded sleeves 25, so that the threaded sleeves 25 move upward under the threaded support of the threaded columns 23, so that the threaded sleeves 25 can fix the threaded columns 23 under the support of the locking blocks 24, so that the threaded columns 23 can support the sampling head 5 through the inner block 22, the round sleeve 21, the outer ring 20, the support rods 19 and the fixing ring 18, so that the support assembly can increase the stability of the sampling head 5 and protect the sampling head 5.

[0034] Working principle: Before using this device, it should be checked first whether there are any problems affecting its use. When the staff needs to use the air particulate sampler to detect air quality, the staff moves the sampling main body 1 to the detection area and fixes the sampling main body 1 through the installation bracket. While pulling the pull ring 16, move the outer cover 12 upward.
