Description

Technical Field

[0001] This utility model relates to the field of toxicology experimental equipment technology, and in particular to a solid-liquid compatible poisoning device. Background Technology

[0002] The HOPE-MED8050 exposure chamber is a professional laboratory device widely used in research on the toxicity of dust, especially in animal experiments. Healthy mice are first selected as experimental animals and randomly assigned to experimental and control groups according to the experimental design. The mice are then placed in the exposure chamber of the exposure chamber, ensuring uniform aerosol concentration distribution at each animal pore, with an error within ±10%. The exposure chamber is then activated, and the dust concentration and exposure time are adjusted according to the experimental protocol, such as exposing mice to a dust concentration of 170-190 mg / m³ for 2 hours daily. Experimental data are monitored and recorded in real time during the exposure process. After the experiment, lung tissue samples from the mice are collected according to the experimental design for pathological examination and biochemical analysis.

[0003] This exposure chamber has two channels: one for inputting solids (via a solid generator), and the other for inputting and atomizing liquids (via a liquid generator). In solid exposure mode, the gas pipe is connected to the solid channel, and the solid dust is blown into the exposure chamber by the gas. In liquid exposure mode, the gas pipe is connected to the liquid channel, and the liquid is atomized by the gas and blown into the exposure chamber. To achieve combined solid-liquid exposure, the atomized liquid and solid dust need to be simultaneously input into the exposure chamber using the same airflow. However, when simultaneously inputting atomized liquid and solid dust, it is impossible to guarantee a uniform aerosol concentration distribution after mixing. Therefore, this invention provides a solid-liquid compatible exposure device to meet this requirement. Utility Model Content

However, this is only for illustrative purposes and is not intended to limit this utility model to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0034] The solid-liquid compatible poisoning device provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0035] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0036] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0037] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0038] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0039] like Figures 1 to 15 As shown, an embodiment of this utility model provides a solid-liquid compatible exposure device, including an exposure cabinet 1. Inside the exposure cabinet 1, a solid generator 101 and an exposure chamber 103 are installed. A liquid generator 102 is installed on the top of the exposure chamber 103. The solid generator 101 and the liquid generator 102 are fixedly connected to the same air inlet pipe. A dust conveying pipe 104 is fixedly connected to the solid generator 101. The liquid generator 102 is connected to a liquid atomizer 2 through a pipe. It also includes a mixing component for mixing solid dust and atomized dust suppressant together. The mixing component is connected to the exposure chamber 103.

[0040] Specifically, the exposure chamber 103 is installed at the center of the bottom inner wall of the exposure cabinet 1. The exposure chamber 103 is a glass cylinder with a hemispherical top and a circular groove on its side wall for placing mice into the chamber. The solid generator 101 is fixedly connected to a corner of the bottom inner wall of the exposure cabinet 1 and is a container for holding solid dust. The liquid generator 102 is installed on the top outer wall of the exposure chamber 103 and can control the atomization of the dust suppressant. The solid generator 101 and the liquid generator 102 are both prior art and will not be described in detail. The gas pipeline is split into two. One gas pipeline is connected to the solid generator 101, and the dust is blown into the exposure chamber 103 from the dust conveying pipe 104 that is fixedly connected to it. The other gas pipeline is connected to the liquid generator 102 and connected to the liquid atomizer 2 through a pipe. The atomized dust suppressant is discharged into the exposure chamber 103 from several round holes opened near the top of the outer wall of the liquid atomizer 2. A portion of the dust suppressant is left in the liquid atomizer 2. This ensures that the dust suppressant and solid dust are simultaneously input into the contamination cabinet 1 under the same airflow conditions.

[0041] The mixing component provided by this invention can mix solid dust and atomized dust suppressant together, ensuring that the concentration of the resulting aerosol is evenly distributed within the chamber of the exposure chamber 103. During the mixing process, the component can also collect agglomerates formed by the accelerated settling of the atomized dust suppressant and dust, preventing these agglomerates from falling into the chamber of the exposure chamber 103 and thus avoiding accidental ingestion by mice, which could affect experimental results. Furthermore, the dust-suppressing effect of the suppressant can be judged by observing the amount of agglomerates. A higher number of agglomerates indicates less dust inhaled by the mice, suggesting a better dust-suppressing effect; conversely, fewer agglomerates indicate a poorer dust-suppressing effect.

[0042] like Figures 3 to 5 As shown, the hybrid assembly includes a circular partition 3 fixedly connected to the inner wall of the exposure chamber 103. A guide cylinder 201 is fixedly connected to the top outer wall of the circular partition 3. Four S-shaped elastic plates 202 are fixedly connected to the outer wall of the guide cylinder 201. A circular sleeve plate 203 is fixedly connected to one end of each S-shaped elastic plate 202. Two first connecting plates 204 are symmetrically arranged on the outer wall of the circular sleeve plate 203. A barrier plate 205 is fixedly connected to one end of each first connecting plate 204. Two second connecting plates 206 are symmetrically arranged on the outer wall of the circular sleeve plate 203. An abutment plate 207 is fixedly connected to one end of each second connecting plate 206.

[0043] Specifically, the circular partition 3 is fixedly connected to the inner wall of the exposure chamber 103 near the top. The circular partition 3 is a glass disc. This arrangement divides the chamber of the exposure chamber 103 into an upper chamber and a lower chamber. One end of the guide cylinder 201 is fixedly connected to the center of the outer wall of the top of the circular partition 3. The guide cylinder 201 is composed of two metal cylinders with different diameters. The other end of the guide cylinder 201 is fixedly connected to the inner wall of the top of the exposure chamber 103. One-way valves are installed on the inner walls of the dust conveying pipe 104 and the guide cylinder 201 mentioned above. The one-way valves are existing technology and will not be described in detail. This configuration allows the atomized dust suppressant discharged from the liquid atomizer 2 and the dust from the solid generator 101 to be guided separately into the lower chamber of the exposure chamber 103, preventing the mixed aerosol from flowing back into the guide cylinder 201 and the dust conveying pipe 104. Four S-shaped elastic plates 202 are fixedly connected at one end to the outer wall of the guide cylinder 201, arranged in a circular array. The S-shaped elastic plates 202 are "S"-shaped plastic plates, and the other ends of all four S-shaped elastic plates 202 are fixedly connected to the same circular sleeve plate 203. The circular sleeve plate 203 is... A hollow plastic circular plate has two first connecting plates 204 symmetrically fixedly connected to the outer wall of a circular sleeve plate 203. The first connecting plate 204 is a straight plastic plate, and a barrier plate 205 is fixedly connected to one end of the first connecting plate 204. The barrier plate 205 is a square plastic plate with an arc at its bottom end. Two second connecting plates 206 are symmetrically fixedly connected to the outer wall of the circular sleeve plate 203. The second connecting plates 206 are straight plastic plates. The top outer wall of two abutting plates 207 is fixedly connected to the bottom outer wall of the second connecting plate 206. The abutting plates 207 are straight plastic plates.

[0044] When the abutment plate 207 is supported by the bottom of the exposed chamber 103, it will displace away from the bottom of the exposed chamber 103, causing the second connecting plate 206 to displace in the same direction. At this time, the circular sleeve plate 203 will also displace in the direction of the displacement of the second connecting plate 206, causing the S-shaped elastic plate 202 to deform along its bending direction. Meanwhile, the first connecting plate 204, the barrier plate 205, the circular sleeve plate 203, the second connecting plate 206 and the abutment plate 207 are an integrated structure, and the barrier plate 205 will displace along with the displacement of the abutment plate 207. When the abutment plate 207 is no longer supported by the bottom of the exposure chamber 103, the S-shaped elastic plate 202 will recover its deformation under its own elasticity and push the circular sleeve plate 203 to move away from the top of the exposure chamber 103. At this time, the first connecting plate 204 and the second connecting plate 206 will also move in the same direction as the circular sleeve plate 203. Subsequently, the barrier plate 205 and the abutment plate 207 will move in the same direction as the first connecting plate 204 and the second connecting plate 206. This setup can open the barrier plate 205 by applying force to the abutment plate 207, allowing the mixed aerosol to leak from the barrier plate 205 into the lower chamber of the exposure chamber 103 to complete the mouse exposure. When the abutment plate 207 is no longer under force, it will reset under the elasticity of the S-shaped elastic plate 202, and then it can wait for the next experiment.

[0045] like Figures 3 to 13 As shown, a brushless motor 301 is fixedly connected to the top outer wall of the circular partition 3, and a first piston tube 302 is fixedly connected to the bottom outer wall of the circular partition 3. A first push rod 303 is slidably connected to the inner wall of the first piston tube 302, and several push teeth 308 are fixedly connected to one side outer wall of the first push rod 303. A connecting pipe 304 is fixedly connected to one end of the first piston tube 302, and the end of the connecting pipe 304 away from the first piston tube 302 has two forks. A second piston tube 305 is fixedly connected to each of the two forks, and a second push rod 307 is slidably connected to the inner wall of the second piston tube 305. One end of the second push rod 307 is fixedly connected to a movable plate 4. Two second sliding grooves 401 are opened on the top outer wall of the movable plate 4. A second spring 402 is fixedly connected to the inner wall of one end of the second sliding groove 401. A connecting limit post 701 is fixedly connected to one end of the second spring 402. A vent hole 403 is opened on the top outer wall of the movable plate 4. A vent support plate 404 is installed on the vent hole 403. Limit support posts 405 are symmetrically arranged on both sides of the top outer wall of the movable plate 4.

[0046] Specifically, the brushless motor 301 is fixedly connected to the top outer wall of the circular partition 3. The brushless motor 301 is existing technology and will not be described in detail. One end of the first piston tube 302 is fixedly connected to the bottom outer wall of the circular partition 3. The first piston tube 302 is a hollow metal cylinder. The first push rod 303 is slidably connected to the inner wall of the first piston tube 302, allowing it to move like a piston on the inner wall of the first piston tube 302. The first push rod 303 consists of a plastic square column and a plastic cylinder. Several push teeth 308 are fixedly connected to one side outer wall of the first push rod 303 in a linear array. The push teeth 308 can mesh with the gears on the brushless motor 301. One end of the connecting pipe 304... The connecting pipe 304 is a plastic hose filled with liquid, which is fixedly connected to the outer wall of the bottom end of the first piston tube 302. The end of the hose away from the first piston tube 302 has two forks, which are fixedly connected to the outer walls of the bottom ends of the two second piston tubes 305 respectively. The second piston tube 305 consists of three parts: a hollow metal round tube and two hollow metal round plates. The second push rod 307 is slidably connected to the inner wall of the second piston tube 305 and can perform piston movement on the inner wall of the second piston tube 305. The second push rod 307 consists of two parts: a metal cylinder and a metal round plate.

[0047] When the brushless motor 301 rotates, causing the first push rod 303 to move towards the connecting pipe 304, it pushes the liquid in the connecting pipe 304 towards the second piston tube 305. At this time, the second push rod 307 is pushed away from the connecting pipe 304 by the liquid. Conversely, when the brushless motor 301 rotates, causing the first push rod 303 to move away from the connecting pipe 304, it pushes the liquid in the connecting pipe 304 away from the second piston tube 305. The two push rods 307 are driven to move towards the connecting pipe 304. The ends of the two push rods 307 away from the second piston tube 305 are symmetrically fixed to both sides of the bottom outer wall of the movable plate 4. The movable plate 4 is a plastic square plate. The movable plate 4 will move towards or away from the circular partition 3 as the brushless motor 301 rotates. The two second sliding grooves 401 are opened on the top outer wall of the movable plate 4 and are symmetrical about the center of the movable plate 4. One end of the second spring 402 is fixedly connected to the outer wall of one end of the second sliding groove 401. The limiting post 701 is fixedly connected to the other end of the second spring 402. The limiting post 701 consists of two parts: a quarter-cylinder plastic cylinder and a "convex" shaped plastic protrusion. A circular vent hole 403 is opened at the center of the outer wall of the top of the movable plate 4. A vent support plate 404 is installed on the inner wall of the vent hole 403. The vent support plate 404 consists of two parts: a plastic circular plate with several circular holes and a square plastic plate. Square protrusions are provided on the outer walls of the square plastic plate near the circular plate at both ends. The limiting support post 405 is symmetrically fixedly connected to the movable plate 4. On both sides of the outer wall at the top of the middle section, and near the vent 403, there are grooves with appropriate square protrusions. This design facilitates disassembly and installation. When the connecting limit post 701 is pulled away from the second spring 402, the second spring 402 will be subjected to force and move along its bending direction. The above structure allows the movable plate 4 to mix solid dust and atomized dust suppressant together when the brushless motor 301 rotates, and discharge it from the vent 403. This can make the concentration of the aerosol formed after mixing uniformly distributed, improving the accuracy of the experiment.

[0048] like Figures 6 to 15As shown, two second piston tubes 305 are respectively fitted with snap-fit ​​plates 306 on their outer walls. A first fixing plate 5 is fixedly connected to the top outer wall of each snap-fit ​​plate 306. C-shaped buckles 501 are symmetrically arranged on the outer walls of both ends of the first fixing plate 5. Second fixing plates 509 are symmetrically arranged on both ends of the outer wall of one side of the first fixing plate 5. A first sliding groove 502 is symmetrically formed on the outer wall of one side of the first fixing plate 5. A C-shaped support plate 506 is symmetrically arranged on the outer wall of the bottom end of the first fixing plate 5. A first fixing post 507 is fixedly connected to one end of the C-shaped support plate 506. A rotating cylinder 508 is rotatably connected to the outer wall of the first fixing post 507. An arc-shaped shovel plate 6 is slidably connected to the inner wall of the first sliding groove 502. A first spring 504 is fixedly connected to the top inner wall of the first sliding groove 502. A connecting post 505 is fixedly connected to one end of the first spring 504. A limit plate 503 is fixedly connected to one end of the connecting post 505.

[0049] Specifically, the inner wall of the snap-fit ​​plate 306 snaps onto the outer wall of the corresponding second piston tube 305. The snap-fit ​​plate 306 consists of two parts: an "L"-shaped metal plate and a "C"-shaped metal plate. The end of the snap-fit ​​plate 306 with the "C"-shaped metal plate snaps onto the outer wall between two hollow metal circular plates near the top of the second piston tube 305. This not only facilitates the installation of the snap-fit ​​plate 306 and the second piston tube 305, but also limits and fixes the second piston tube 305. Two first fixing plates 5 are respectively fixedly connected to the top outer walls of the two snap-fit ​​plates 306. The first fixing plates 5 are square metal plates, and their top ends are fixedly connected to the aforementioned... On the circular partition 3, C-shaped buckles 501 are symmetrically fixed to the outer walls of both ends of the first fixed plate 5. The C-shaped buckles 501 are "C"-shaped plastic plates. One end of two C-shaped support plates 506 are symmetrically fixed to both sides of the bottom outer wall of the first fixed plate 5. The C-shaped support plates 506 are "C"-shaped plastic plates. The other end of the C-shaped support plates 506 is fixedly connected to a fixed column. The fixed column is a plastic cylinder. A rotating cylinder 508 is rotatably connected to the outer wall of the fixed column. The rotating cylinder 508 is a hollow plastic cylinder. Two second fixed plates 509 are symmetrically fixed to both ends of the outer wall of the first fixed plate 5 near the movable plate 4. The second fixed plates 509 are metal square plates.

[0050] Two first sliding grooves 502 are symmetrically opened at both ends of the outer wall of the first fixed plate 5 near the movable plate 4. The first sliding groove 502 is a square straight groove. One end of the arc-shaped shovel 6 is slidably connected to the inner wall of the first sliding groove 502. The arc-shaped shovel 6 is composed of three parts: a curved metal plate and two cylindrical plastic protrusions. One end of the first spring 504 is fixedly connected to the middle position of the top inner wall of the first sliding groove 502. The first spring 504 is disclosed in the prior art and will not be described in detail. The other end of the first spring 504 is fixedly connected to the outer wall of the connecting post 505 near the top. The connecting post 505 is a plastic cylinder. The end of the connecting post 505 away from the first spring 504 is fixedly connected to the middle position of the top outer wall of the limiting plate 503. The limiting plate 503 is a semi-circular arc-shaped plastic plate. The overall contour of the limiting plate 503 is adapted to the contour of the cylindrical plastic protrusions on the arc-shaped shovel 6.

[0051] When the brushless motor 301 rotates in the forward direction, it will cause the movable plate 4 to move towards the inner wall of the top of the exposed chamber 103. This will cause the arc-shaped shovel 6 to move in the same direction along the inner wall of the first sliding groove 502. When the movable plate 4 moves, the outer wall of the cylindrical plastic protrusion on the arc-shaped shovel 6 will abut against the bottom outer wall of the limiting plate 503, and cause the limiting plate 503 to move along the inner wall of the first sliding groove 502 towards the inner wall of the top of the exposed chamber 103. At this time, the first spring 504 will be stressed and deform along its own bending direction until the ventilation support plate 404 on the movable plate 4 abuts the top outer wall of the abutment plate 207 against the bottom outer wall of the circular partition 3. When the brushless motor 301 rotates in the reverse direction, the movable plate 4 is pulled away from the circular partition 3. At this time, the first spring 504 will recover its deformation under its own elasticity, pushing the limiting plate 503 to move towards the movable plate 4. The arc-shaped shovel 6 will also move towards the movable plate 4 under the push of the limiting plate 503. During the movement of the arc-shaped shovel 6, the outer wall of the side closest to the second fixed plate 509 will rotate under the contact of the outer wall of the second fixed plate 509 and return to its initial shape. This structure can scoop up the agglomerates on the sterile pad 7 and pour out the scooped agglomerates when the movable plate 4 moves towards the inner wall of the top of the exposure chamber 103.

[0052] A sterile pad 7 is fixedly connected to the outer wall of the second fixing post 702. The second fixing post 702 is snapped onto the inner wall of the C-shaped buckle 501. A dust collection box 8 is fixedly connected to the outer wall of the second fixing post 702. A third sliding groove 801 is provided at the bottom of the dust collection box 8. A sliding plate 802 is slidably connected to the inner wall of the third sliding groove 801. Specifically, one end of the two sterile pads 7 is fixedly connected to the outer wall of the two second fixing posts 702 near the circular partition 3, and they are distributed in a mirror image. The sterile pads 7 are made of rubber and are rolled up on the outer wall of the rotating cylinder 508. The other end is fixedly connected to the outer wall of the connecting limiting post 701 near the second fixing plate 509.

[0053] When the movable plate 4 moves toward the inner wall of the top of the exposure chamber 103, the middle part of the sterile pad 7 is limited by the rotating cylinder 508. In conjunction with the second sliding groove 401 limiting the connecting limiting post 701, the sterile pad 7 adheres to the outer wall of the top of the movable plate 4 during the movement of the movable plate 4 toward the inner wall of the top of the exposure chamber 103. It also pulls the connecting limiting post 701 to slide along the inner wall of the second sliding groove 401 toward the second fixed plate 509. At this time, the second spring 402, which is fixedly connected to the connecting limiting post 701, will be pulled by the connecting limiting post 701 and deform along its own bending direction. When the movable plate 4 moves away from the top inner wall of the exposure chamber 103, the second spring 402 is no longer under tension and recovers its deformation under its own elasticity. This will pull the connecting limit post 701 to slide along the inner wall of the second sliding groove 401 towards the ventilation support plate 404. The sterile pad 7, which is fixedly connected to the outer wall of one side of the connecting limit post 701, will slide against the top outer wall of the movable plate 4 towards the second fixed plate 509 under the action of the connecting limit post 701.

[0054] The outer wall of the second fixed column 702 is snapped onto the inner wall of the C-type buckle 501. The second fixed column 702 is a plastic cylinder. The dust collection box 8 is fixedly connected to the outer wall of the second fixed column 702. The dust collection box 8 is a plastic box with an open top. A third sliding groove 801 is provided at the bottom of the box. A sliding plate 802 is slidably connected to the inner wall of the third sliding groove 801. A handle is installed at one end of the sliding plate 802, and semi-circular raised square plastic plates are provided on both sides. The outline of the third sliding groove 801 matches the outline of the sliding plate 802. When the device needs to be cleaned, simply pull the handle to pull out the sliding plate 802, and the collected agglomerates can be easily cleaned out. This design can collect and store agglomerates formed by the accelerated settling of the atomized dust suppressant and dust. It can also clean out the agglomerates collected in the dust collection box 8 when the staff maintains the device.

[0055] The working principle of this utility model is as follows:

[0056] In use, the mouse is first placed in the exposure chamber 103. Then, the atomized dust suppressant and solid dust are simultaneously introduced through the gas pipe into the rectangular sealed space formed by the two first fixed plates 5, the two second fixed plates 509, the movable plate 4, and the circular partition 3 via the guide tube 201 and the dust conveying pipe 104. During the mixing process of the atomized dust suppressant and solid dust, the agglomerates formed by accelerated settling will fall onto the sterile pad 7. At this time, the brushless motor 301 can be started. When the brushless motor 301 rotates, it drives the first push rod 303 to move in the direction of the connecting pipe 304, which will push the connecting pipe. The liquid in 304 is displaced towards the second piston tube 305. At this time, the second push rod 307 is pushed away from the connecting pipe 304 by the liquid. The movable plate 4 is displaced towards the circular partition 3 under the push of the second push rod 307. During the displacement of the movable plate 4, the atomized dust suppressant and solid dust in the rectangular sealed space are compressed and mixed together. At the same time, the sterile pad 7 pulls the connecting limit post 701 to slide towards the second fixed plate 509 on the inner wall of the second sliding groove 401. The second spring 402 is stretched and deforms along its bending direction.

[0057] The ventilation support plate 404 will move along with the movable plate 4 and will abut against the bottom outer wall of the abutment plate 207. When the abutment plate 207 is supported by the bottom of the exposed chamber 103, it will move away from the bottom of the exposed chamber 103, which will cause the second connecting plate 206 to move in the same direction. At this time, the circular sleeve plate 203 will also move in the direction of the second connecting plate 206, which will cause the S-shaped elastic plate 202 to deform along its bending direction. At the same time, the first connecting plate 204 will move along with the circular sleeve plate 203, which will cause the barrier plate 205 to move in the direction of the abutment plate 207. When the abutment plate 207 is no longer supported by the bottom of the exposed chamber 103, the S-shaped elastic plate 202 will recover its deformation under its own elasticity and push the circular sleeve plate 203 to move away from the top of the exposed chamber 103. At this time, the first connecting plate 204 and the second connecting plate 206 will also move in the same direction as the circular sleeve plate 203. Subsequently, the barrier plate 205 and the abutment plate 207 will move in the same direction as the first connecting plate 204 and the second connecting plate 206.

[0058] When the brushless motor 301 rotates forward, driving the first push rod 303 to move towards the connecting pipe 304, it pushes the liquid in the connecting pipe 304 towards the second piston pipe 305. At this time, the second push rod 307 is driven to move away from the connecting pipe 304, while the movable plate 4 moves towards the inner wall of the top of the exposure chamber 103, driving the arc-shaped shovel 6 to move in the same direction along the inner wall of the first sliding groove 502. When the movable plate 4 moves towards the inner wall of the top of the exposure chamber 103, the middle of the sterile pad 7 is limited by the rotating cylinder 508. In conjunction with the second sliding groove 401 limiting the connecting limiting post 701, the sterile pad 7 adheres to the outer wall of the top of the movable plate 4 during the movement of the movable plate 4 towards the inner wall of the top of the exposure chamber 103, and pulls the connecting limiting post 701. 1. The curved shovel 6 slides along the inner wall of the second sliding groove 401 toward the second fixed plate 509. The curved shovel 6 can scoop up the agglomerates on the sterile pad 7. At the same time, during the displacement of the movable plate 4, the outer wall of the cylindrical plastic protrusion on the curved shovel 6 will abut against the bottom outer wall of the limiting plate 503, and drive the limiting plate 503 to move along the inner wall of the first sliding groove 502 toward the top inner wall of the exposure chamber 103. At this time, the first spring 504 will be stressed and deform along its own bending direction until the ventilation support plate 404 on the movable plate 4 abuts the top outer wall of the abutment plate 207 against the bottom outer wall of the circular partition 3. At this time, the curved shovel 6 will rotate under the limitation of the first sliding groove 502, in coordination with the guidance and abutment of the curved outer wall on the connecting limiting post 701, and pour the scooped agglomerates into the dust collection box 8 from the gap left after the partition plate 205 is displaced. When the experiment is completed and the device needs cleaning and maintenance, simply pull the handle to remove the sliding plate 802 to clean out the collected agglomerates. At the same time, the vents 403, which were originally covered by the two sterile pads 7, will gradually open during the movement of the movable plate 4, and the mixed solid dust and atomized dust suppressant will be discharged from the vents 403.

[0059] When the brushless motor 301 rotates in reverse, it will cause the first push rod 303 to move away from the connecting pipe 304, and the liquid in the connecting pipe 304 to move away from the second piston tube 305. At this time, the second push rod 307 will be driven to move towards the connecting pipe 304. The movable plate 4 will be pulled away from the circular partition 3. At this time, the first spring 504 will recover its deformation under its own elasticity, pushing the limiting plate 503 to move towards the movable plate 4. The arc-shaped shovel 6 will also move towards the movable plate 4 under the push of the limiting plate 503. During the displacement of the shovel plate 6, the outer wall of the side closest to the second fixed plate 509 will rotate under the resistance of the outer wall of the second fixed plate 509 and return to its initial shape. The second spring 402 will no longer be under tension and will recover its deformation under its own elasticity. It will pull the connecting limit post 701 to slide along the inner wall of the second sliding groove 401 towards the ventilation support plate 404. The sterile pad 7 fixedly connected to the outer wall of the connecting limit post 701 will slide against the top outer wall of the movable plate 4 towards the second fixed plate 509 under the action of the connecting limit post 701. The two sterile pads 7 will cover the ventilation hole 403 again, waiting for the next round of experiments.
