[0024] Embodiment 1:

[0025] Please refer to Figures 1-4 As shown, the present utility model is a dust collector for occupational health detection, including

[0026] a housing 1, two sampling cylinders 2 are fixedly connected to one side wall of the housing 1, and a sampling head cover 3 is assembled on one side of the sampling cylinder 2 through a thread;

[0027] a filter screen installation component, the filter screen installation component is arranged inside the sampling cylinder 2, and the filter screen installation component includes a mounting ring 4, a magnetic attraction cylinder 5, a filter disk 6 and a metal column 7. The mounting ring 4 is installed on the inner wall of the sampling cylinder 2. Four mounting slots are arranged in a circumferential array on one side wall of the mounting ring 4. The four magnetic attraction cylinders 5 are respectively connected to the four mounting slots. The four metal columns 7 are fixedly arranged in a circumferential array on one side wall of the filter disk 6. The metal column 7 is made of metal iron. The magnetic attraction cylinder 5 and the metal column 7 are connected by magnetic attraction and insertion;

[0028] a negative pressure component, the negative pressure component is arranged inside the housing 1;

[0029] a regulation component, the regulation component is arranged on one side outside the housing 1 and is connected to the negative pressure component for control.

[0030] Specifically, when the tester selects a filter disk 6 of a suitable specification model, the tester first disassembles and separates the sampling head cover 3 from the sampling cylinder 2. Further, the filter disk 6 is placed inside the sampling cylinder 2, and by using the characteristic that the magnetic attraction cylinder 5 and the metal column 7 are connected by magnetic attraction and insertion, the metal column 7 is placed inside the magnetic attraction cylinder 5 for adsorption and insertion, and then the filter disk 6 is installed, and the operation is fast.

[0031] An auxiliary handle 8 is fixedly connected to the outer wall of the housing 1.

[0032] The negative pressure component includes an air pump 9 and a flow meter 10, and both the air pump 9 and the flow meter 10 are fixedly arranged inside the housing 1.

[0033] One end of the flowmeter 10 is connected to a negative pressure pipe 11. The negative pressure pipe 11 is in a Y shape. Two through holes are formed in one side wall of the housing 1, and the through holes are communicated with the sampling cylinder 2. The two ends of the negative pressure pipe 11 away from the flowmeter 10 are respectively connected to the two through holes. A first diversion pipe 12 is communicated between the flowmeter 10 and the air pump 9. A second diversion pipe 13 is communicated with the outer wall of the air pump 9, and one end of the second diversion pipe 13 penetrates through the inner wall of the housing 1 and extends to the outside of one side.

[0034] A power supply block 14 and a control module box 15 are fixedly connected to the inner side wall of the housing 1. The power supply block 14 is arranged on one side of the control module box 15.

[0035] The regulation assembly includes a control panel 16 and control knobs 17. The control panel 16 is fixedly arranged on the outer side wall of the housing 1, and the two control knobs 17 are arranged on one side wall of the housing 1.

[0036] As can be seen from the above, after selecting a suitable filter disk 6 and installing the filter disk 6 into the sampling cylinder 2 through the filter screen installation assembly, the operator starts the air pump 9 and the flowmeter 10 through the control panel 16. Under the action of the air pump 9, it is convenient to form a negative pressure environment inside the sampling cylinder 2, further adsorb the dust in the air onto the surface of the filter disk 6, and then sample the dust in the air. After the sampling is completed, the operator separates the sampling head cover 3 from the sampling cylinder 2, and further removes the filter disk 6 for subsequent analysis.

[0037] Among them, the flowmeter 10 is set to monitor and adjust the air flow rate to ensure a consistent flow velocity during the sampling process.

[0038] Embodiment 2:

[0039] When the device is applied to an actual scenario, the tester moves the device to the place where air dust detection is to be carried out through the auxiliary handle 8. Among them, the filter screens of the dust sampler usually have different specifications and models. Different filter screen specifications can meet different sampling requirements, such as filtering dust of different particle sizes or adapting to different sampling flow rates. The specific filter screen specifications and models are usually listed in the user manual of the device. Therefore, before dust sampling, the operator selects a suitable model of the filter disk 6 and quickly and conveniently installs the filter disk 6 through the set filter screen installation assembly, which is convenient for subsequent operators to perform dust detection analysis, surface cleaning, and overall replacement of the filter disk 6.
