It plays a crucial role in environmental monitoring, industrial production, scientific research, and healthcare.

[0003] According to Chinese Announcement No. CN223091798U, a microparticle detection device includes a housing, an optical detection cavity inside the housing, and two independent air ducts penetrating the optical detection cavity.

The lens is positioned close to the light source, and the break, lens, and light source are arranged coaxially.

[0004] During the air intake process, impurities in the air are drawn into the detection area. These impurities accumulate in the detection area and can reduce the accuracy of the detection in the next batch of air intake tests. Utility Model Content

[0023] Reference Figure 1-4 A microparticle detection device includes: a detection device body, a storage cleaning component 4, and a vibration separation component 5. The detection device body includes a storage box 1, a microparticle detector 2, and a micro air pump 3. The storage box 1 has two sets of holes. The microparticle detector 2 and the micro air pump 3 are respectively arranged on both sides of the outer wall of the storage box 1. The microparticle detector 2 is connected to one set of holes in the storage box 1 through a pipe. The air inlet and outlet of the micro air pump 3 are both provided with pipes. The other end of the pipe at the air outlet of the micro air pump 3 is connected to the other set of holes in the storage box 1. The storage cleaning component 4 is arranged inside the storage box 1, and the vibration separation component 5 is arranged inside the storage cleaning component 4.

[0024] The storage-type cleaning component 4 includes a box cover 401 positioned directly above the storage box 1. A sealing ring is provided on the bottom outer wall of the box cover 401. A rectangular hole is provided in the center of the box cover 401. A guide rod 402 is horizontally welded to the top outer wall of the box cover 401. One end of the guide rod 402 has an integrally formed protrusion. A trapezoidal block 403 is horizontally slidably mounted on the guide rod 402. An orifice-shaped positioning block 404 is welded to the outer wall of the storage box 1. The trapezoidal block 403 is located inside the orifice-shaped positioning block 404. A first spring 405 is sleeved on the guide rod 402. The two ends of the first spring 405 are respectively welded to the protrusion of the guide rod 402 and the outer wall of the trapezoidal block 403. A C-shaped connecting block 406 is welded to the outer wall below the rectangular hole of the box cover 401. A storage box 407 is welded to the bottom end of the C-shaped connecting block 406. The size of the storage box 407 is adapted to the internal size of the storage box 1.

[0025] The vibration separation assembly 5 includes a pressing rod 501 that is vertically slidably disposed inside a rectangular hole in the box cover plate 401. The pressing rod 501 has an I-shaped cross-section. A limiting block 502 is welded inside the C-shaped connecting block 406. A hole is opened inside the limiting block 502. The pressing rod 501 is slidably disposed inside the hole of the limiting block 502. A striking block 503 is welded to the outer wall of the pressing rod 501. The top end of the striking block 503 is attached to the bottom outer wall of the box cover plate 401. A second spring 504 is sleeved on the outside of the pressing rod 501. The two ends of the second spring 504 are respectively attached to the outer walls of the limiting block 502 and the pressing rod 501.

[0026] In this invention, a miniature air pump 3 delivers gas into the storage box 1. At this time, the microparticle detector 2 comes into contact with the air inside the storage box 1. When the microparticle detector 2 is working, the air particles will scatter the light when they pass through a beam of strong light. The scattered light is collected by the lens and focused onto the photosensitive element, converting the weak light pulse signal into an electrical pulse signal. After the electrical pulse is amplified and distinguished, the processor determines the size of the particles based on the amplitude of the pulse, thereby realizing the detection of air particles. When it is necessary to clean the impurities carried in the air by the storage box 1, the vibration separation component 5 knocks and separates the impurities attached to the inner wall of the storage box 1, causing the stationary impurities to fall above the collection cleaning component 4 for collection. The vertical displacement of the collection cleaning component 4 enables rapid cleaning.

[0027] Pushing the pressing rod 501 vertically downwards allows it to move vertically downwards within the rectangular hole of the box cover 401. At this time, the striking block 503 connected to the pressing rod 501 moves vertically downwards together. When the pressing rod 501 is no longer pressed, the second spring 504 above the limiting block 502 inside the C-shaped connecting block 406 pushes the pressing rod 501 vertically upwards to quickly reset. During the vertical reset process, the striking block 503 on the pressing rod 501 contacts the box cover 401 by striking, causing the box cover 401 to vibrate. Because the storage box 1 is connected to the box cover 401, impurities attached to the inner wall of the storage box 1 fall into the storage box 407 connected to the box cover 401 via the C-shaped connecting block 406.

[0028] By holding the trapezoidal block 403 and moving it on the guide rod 402, the trapezoidal block 403 is no longer pushed and displaced by the first spring 405. As a result, the trapezoidal block 403 is no longer inside the mouth-shaped positioning block 404. At this time, the box cover 401 can be moved vertically upward. During the vertical movement, the storage box 407 at the bottom of the box cover 401 will remove the impurities that have fallen off the inner wall of the storage box 1, thereby cleaning the inside of the storage box 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
