[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Reference Figures 1-4 This utility model provides a technical solution: a particulate matter cleanliness detection device, including a detection platform 1 and a feeding detection mechanism. A mounting frame 2 is installed on the rear side of the top of the detection platform 1, and a detection lens 3 is installed on the front of the mounting frame 2. A mounting cover 4 is provided on the top of the detection platform 1, which can add multiple sets of particulate matter to be detected to the feeding detection mechanism. By rotating the feeding detection mechanism, the particulate matter to be detected is rotated sequentially under the detection lens 3, thereby facilitating the detection of particulate matter.

[0030] Reference Figures 1-2In a preferred embodiment, a feeding and detection mechanism is provided, comprising a placement tray 5, a mounting rod 6, a through hole 7, and a mounting plate 8. The placement tray 5 is positioned on top of the detection platform 1, and the mounting rod 6 is mounted on top of the detection platform 1, with its top connected to the top of the inner wall of the mounting cover 4. The through holes 7 are respectively opened at the four corners of the top of the placement tray 5. The mounting plate 8 is embedded in the inner cavity of the through hole 7, which can support the mounting cover 4 after the mounting rod 6 is installed, so that the placement tray 5 can be rotated to rotate the through hole 7 to the light source position set on the detection platform 1, thereby facilitating the rotation of the particles under the detection lens 3 for particle detection. The mounting plate 8 is made of transparent material, so that the light source in the detection platform 1 can illuminate the particles, thereby facilitating particle detection. A rotating ring 13 is fixedly installed on the surface of the placement tray 5, and the surface of the rotating ring 13 has several anti-slip grooves, which facilitates the rotation of the placement tray 5 by rotating the ring 13, and the anti-slip grooves provide an anti-slip function, thereby facilitating the rotation of the placement tray 5.

[0031] Reference Figures 1-2 In a preferred embodiment, an installation cylinder 9 is installed on the right side of the top of the installation cover 4, and the installation cylinder 9 is connected to the installation cover 4. A placement plate 10 is inserted into the right side of the installation cylinder 9, and several placement plates 10 are provided. A movable frame 11 is installed on the right side of the placement plate 10, and a cover 12 is installed on the top of the installation cylinder 9. The particulate matter to be detected can be placed on the placement plate 10, and then placed in the installation cylinder 9 for temporary storage. The particulate matter can be sprinkled onto the placement plate 10 by moving the movable frame 11, and the cover 12 can seal the installation cylinder 9. The particulate matter on the placement plate 10 can be sprinkled onto the installation plate 8 by pulling the movable frame 11 and the placement plate 10 in stages, thereby facilitating the detection of particulate matter.

[0032] Reference Figures 1-4In a preferred embodiment, the inner cavity of the mounting cover 4 is provided with a shield 16, and extension plates 17 are installed on both sides of the shield 16. A limiting rod 18 is installed on the top of the inner wall of the mounting cover 4, and the bottom of the limiting rod 18 extends to the bottom of the extension plate 17. A spring 19 is installed on the top of the extension plate 17, and the top of the spring 19 is connected to the top of the inner wall of the mounting cover 4. A compression cylinder 20 is installed on the bottom of the extension plate 17. This allows the shield 16 to shield the particles added to the placement plate 10 after installation, preventing the particles from splashing. It also allows the spring 19 to compress the extension plate 17 and the shield 16, and the limiting rod 18 can compress the extension plate 17 and the shield 16. 6. Limiting position facilitates the movement of the shield 16. The surface of the placement tray 5 is equipped with a fixing ring 14, and the surface of the fixing ring 14 is provided with a notch 15. The two sides of the notch 15 are inclined, so that when the fixing ring 14 is rotated by the placement tray 5, it can squeeze the extrusion cylinder 20, so that the extrusion cylinder 20 can move the mounting cover 4 upward through the extension plate 17. This prevents the shield 16 from blocking the particles that fall onto the mounting plate 8 when the placement tray 5 is rotated. After the notch 15 is moved to the bottom of the extrusion cylinder 20 again, the extrusion spring 19 can move the extension plate 17 and the shield 16 downward, so as to block the particles that fall onto the mounting plate 8.

[0033] Reference Figures 1-3 In a preferred embodiment, a collection cylinder 21 is inserted into the top of the mounting cover 4, and a collection pad 22 is installed at the bottom of the inner wall of the collection cylinder 21. The collection pad 22 is made of elastic material, and a fixing plate 23 is installed on both sides of the collection cylinder 21. The top of the fixing plate 23 is provided with a mounting bolt 24. The mounting bolt 24 passes through the fixing plate 23 and is threadedly connected to the mounting cover 4. The fixing plate 23 and the collection cylinder 21 can be installed into the mounting cover 4 by the mounting bolt 24, so that the collection pad 22 fits against the placement plate 5, thereby facilitating the collection of particles on the placement plate 10 onto the collection pad 22 after the placement plate 10 is rotated.

[0034] Specifically, the working process or working principle of this particulate matter cleanliness detection device is as follows: When in use, the cover 12 is opened, and the placement plates 10 are inserted into the mounting cylinder 9 from bottom to top. As the placement plates 10 are inserted, the particulate matter is added to the placement plates 10 in sequence. When detecting the particulate matter, the bottom placement plate 10 is pulled out, so that the particulate matter on the placement plate 10 falls onto the mounting plate 8. The placement disc 5 is rotated, so that the placement disc 5 drives the mounting plate 8 containing the particulate matter to rotate below the detection lens 3, thereby facilitating the detection of the particulate matter that falls onto the mounting plate 8. After a group of particulate matter has rotated to below the detection lens 3, the bottom placement plate 10 is pulled, so that the particulate matter falls onto the mounting plate 8. When a group of particulate matter has rotated to below the detection lens 3, the notch 15 rotates to the downward direction of the extrusion cylinder 20, thereby causing the spring 19 to move the extension plate 17 and the shield 16 downward to shield the mounting plate 8 and prevent particulate matter from splashing.

[0035] It should be noted that the testing station 1 is a device or equipment that exists in the prior art, or a device or equipment that can be implemented by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
