[0021] The inside of the conventional sampling tube is usually provided with a reagent, and indoor air is introduced into the sampling tube to react with the reagent, so as to realize air sampling. However, this sampling method is too simple, and the debris and impurities contained in the air cannot be isolated, resulting in poor quality of the collected sample, which will ultimately affect the detection result.
[0022] Referring to the accompanying Figures 1-4 To solve the above technical problems, an air treatment sampling device is provided, which comprises a shell 10, a fan 20, a control part 30, a sleeve 40, an end cover 50, a core body 60 and an air washing cylinder assembly 70.
[0023] The shell 10 is provided with a fan 20 inside and a control unit 30 outside. The upper end of the shell 10 is connected to a sleeve 40, and the top end of the sleeve 40 is provided with an end cover 50. The inside of the sleeve 40 is provided with a core 60. The lower end of the shell 10 is connected to a gas washing cylinder assembly 70, and the shell 10 is in communication with the outside through the gas washing cylinder assembly 70.
[0024] In the present application, the upper end of the shell 10 is an air inlet, and the lower end is an air outlet. When the fan 20 is working, indoor air is forced to pass through the core 60 and then enter the gas washing cylinder assembly 70. The air entering the gas washing cylinder assembly 70 is adsorbed to remove foreign matter carried in the air, so that the air discharged from the gas washing cylinder assembly 70 does not contain debris and impurities, thereby ensuring high quality of the collected sample and more accurate final test results.
[0025] In addition, the control unit 30 can set parameters such as the amount of collection and air flow rate, thereby realizing controllable sampling. For example, a flow meter is arranged in the shell 10, and the signal output end of the flow meter is in communication with the signal input end of the control unit 30, so that the adjustment and control function can be realized.
[0026] In one embodiment, the top end of the shell 10 and the sleeve 40 are detachably connected, and the sleeve 40 is clamped with the end cover 50.
