[0027] In order to make the technical objectives, technical solutions and technical effects of the present utility model clearer, so as to facilitate those skilled in the art to understand and implement the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] As Figures 1-6 shown, Figure 1 shows a schematic structural diagram of the particle collection structure of the particle collection device according to the preferred embodiment of the present utility model; Figure 2 shows a schematic structural diagram of the main body of the storage box of the particle collection device according to the preferred embodiment of the present utility model; Figure 3 shows Figure 2 a schematic structural diagram of the main body shown in another aspect; Figure 4 shows Figure 2 a schematic structural diagram of the main body shown in yet another aspect; Figure 5 shows a schematic structural diagram of the upper cover of the storage box of the particle collection device according to the preferred embodiment of the present utility model; Figure 6 shows a schematic structural diagram of the lower cover of the storage box of the particle collection device according to the preferred embodiment of the present utility model. Specifically, the particle collection device includes a particle collection structure and a storage box;

[0029] The particle collection structure includes a disc 1, a mucous membrane 2 with a cuttable film, and an adhesive member 3 for adhering the mucous membrane 2 to the disc 1;

[0030] A groove 4 for inserting the disc 1 is formed inside the storage box.

[0031] Based on the above technical solution, when the particle collection device is in use, the particle collection structure is placed at a designated position, and the film on the mucous membrane 2 is torn off, then the particle collection device can be activated to start collecting large particles that naturally settle in the environment. After a certain collection time, the particle collection device is inserted into the groove 4 of the storage box. Since the mucous membrane 2 has adhesiveness, it can stick to the large particles falling on its surface, preventing them from falling during transportation. And because the storage box is well-sealed, it can avoid large particles in the external environment from contaminating the sample during transportation. After the sample is transported to the analysis laboratory, an optical microscope or a scanning electron microscope can be used to quantitatively and qualitatively analyze the large particles. It is also possible to qualitatively analyze the components of the large particles through microscopic infrared testing.

[0032] Furthermore, in this embodiment, the thickness of the disc 1 is 1 mm - 3 mm, preferably 2 mm. The disc 1 has good friction resistance and will not generate particles due to sliding friction with other objects.

[0033] Furthermore, the diameter of the disc 1 can be 90 mm - 95 mm.

[0034] The disc 1 is a plastic part or a metal part.

[0035] The mucosa 2 is square in shape and has dimensions of 5 cm × 5 cm to 8 cm × 8 cm.

[0036] Furthermore, the mucosa 2 includes a film member with adhesiveness on one side and / or a film member with adhesiveness on both sides. The film member can be one layer or multiple layers. When the film member is one layer, the covering film covers above the film member. When the film member is multiple layers, the multiple film members are stacked, and the covering film covers the topmost of the stacked multiple film members.

[0037] In this embodiment, the mucosa 2 includes multiple film members stacked. Before use, tearing off the covering film protecting the topmost layer of the mucosa 2 can activate the particle collection structure; for the mucosa 2 with the covering film torn off, tearing off the used upper surface film member can collect particles again, realizing multiple uses.

[0038] The mucosa 2 can be selected as a dust sticking pad, and the required size can be cut according to the required film area. The adhesive member 3 can be an epoxy tape, a polyacrylate tape, a polyurethane tape, or a double-sided tape.

[0039] Furthermore, in this embodiment, the storage box includes a main body 5, an upper cover 6, and a lower cover 7; the main body 5 is overall in a long strip shape, and its cross-section is U-shaped;

[0040] The main body 5 is uniformly formed with a plurality of grooves 4 in its extending direction;

[0041] The upper cover 6 and the lower cover 7 are respectively detachably mounted on the main body 5 for cooperatively enveloping the main body 5 and accommodating the main body 5 therebetween.

[0042] Here, by designing the cross-section of the main body 5 to be U-shaped, it is ensured that the mucosa 2 does not come into contact with the surface of the main body 5, thereby reducing the collection error. By uniformly forming a plurality of grooves 4 in the extending direction of the main body 5, it is ensured that the disc 1 can be vertically stored and fixed.

[0043] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
