Description

Technical Field

[0001] The invention relates to the technical field of toxicological experimental equipment, and in particular to a system capable of simultaneously conducting solid-liquid two-phase poisoning. Background Art

[0002] HOPE-MED8050 poisoning cabinet is a professional experimental equipment, widely used in dust toxicity research, especially animal experiments. First, healthy mice are selected as experimental animals, and they are randomly divided into experimental and control groups according to the experimental design. Then the mice are placed in the exposure cabin of the poisoning cabinet to ensure that the aerosol concentration of each animal hole is evenly distributed, with an error within ±10%. Then the poisoning cabinet is started, and the dust concentration and exposure time are adjusted according to the experimental plan. For example, the mice are exposed to a dust concentration of 170-190mg / m³ for 2 hours a day. During the poisoning process, the experimental data is monitored and recorded in real time. After the experiment, the mouse lung tissue samples are collected according to the experimental design for pathological examination and biochemical analysis.

[0003] The poison control cabinet is provided with two channels, one for inputting solids (through a solid generator), and the other for inputting liquids and atomizing them (with the help of a liquid generator). If the solid poison control mode is selected, the gas pipeline is connected to the solid channel, and the solid dust will be blown into the exposure chamber of the poison control cabinet under the push of the gas; if the liquid poison control mode is selected, the gas pipeline is connected to the liquid channel, and the liquid will be atomized and blown into the exposure chamber of the poison control cabinet under the action of the gas. In order to achieve the purpose of solid-liquid two-phase combined poison control, it is necessary to use the same airflow to simultaneously input the atomized liquid and solid dust into the exposure chamber. However, when the atomized liquid and solid dust are input at the same time, it is impossible to ensure that the aerosol concentration formed after the two are mixed is evenly distributed. Therefore, the present invention provides a system that can simultaneously perform solid-liquid two-phase poison control to meet the needs. Summary of the invention

[0040] It will be understood that the meanings of “on,” “over,” and “above” in the present invention should be interpreted in the broadest manner, so that “on” not only means “directly on” something, but also includes the meaning of being “on” something with intervening features or layers therebetween, and “on” or “over” not only means “on” or “above” something, but also includes the meaning of being “on” or “above” something with no intervening features or layers therebetween.

[0042] like Figures 1 to 15 As shown, an embodiment of the present invention provides a system that can simultaneously perform solid-liquid two-phase contamination, including a contamination cabinet 1, wherein a solid generator 101 and an exposure chamber 103 are installed inside the contamination cabinet 1, 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, and the liquid generator 102 is connected to a liquid atomizer 2 through a pipe; and also includes a mixing component, the mixing component is used to mix solid dust and atomized dust suppressant together, and the mixing component is connected to the exposure chamber 103.

[0043] Specifically, the exposure chamber 103 is installed at the center of the bottom inner wall of the poison 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 in the chamber of the exposure chamber 103. The solid generator 101 is fixedly connected to a corner of the bottom inner wall of the poison cabinet 1 and is a container for placing solid dust. The liquid generator 102 is installed on the top outer wall of the exposure chamber 103. The liquid generator 102 can control the atomization of the dust suppressant. The solid generator 101 and the liquid generator 102 are both disclosed in the prior art, so they are not described in detail. The gas pipeline is divided into two, one of which is connected to the solid generator 101, and the dust is blown into the exposure chamber 103 from the dust conveying pipe 104 fixedly connected thereto, while the other gas pipeline is connected to the liquid atomizer 2 connected to the liquid generator 102 through a pipeline, and the atomized dust suppressant is discharged into the exposure chamber 103 from a plurality of circular holes opened on the outer wall of the liquid atomizer 2 near the top, and a portion of the dust suppressant is retained in the liquid atomizer 2, so that the dust suppressant and solid dust can be simultaneously input into the contamination cabinet 1 under the same airflow.

[0044] The mixing assembly provided by the present invention can mix solid dust and atomized dust suppressant together, so that the concentration of the aerosol formed after mixing is evenly distributed in the chamber of the exposure chamber 103. The mixing assembly can also collect agglomerates formed by the atomized dust suppressant and dust after the atomized dust suppressant is combined and accelerated to settle during the mixing of solid dust and atomized dust suppressant, so as to prevent the agglomerates from falling into the chamber of the exposure chamber 103 and prevent mice from accidentally eating them, thereby affecting the experimental results. In addition, the dust reduction effect of the inhibitor can also be judged by observing the number of agglomerates. If there are more agglomerates, it means that the mice inhale less dust, which indicates that the dust reduction effect is better; on the contrary, if there are fewer agglomerates, the dust reduction effect is poor.

[0045] like Figures 3 to 5 As shown, the mixing assembly includes a circular baffle 3 fixedly connected to the inner wall of the exposure cabin 103, a guide cylinder 201 is fixedly connected to the top outer wall of the circular baffle 3, four S-shaped elastic plates 202 are fixedly connected to the outer wall of the guide cylinder 201, and one end of the S-shaped elastic plate 202 is fixedly connected to a circular sleeve plate 203. Two first connecting plates 204 are symmetrically arranged on the outer wall of the circular sleeve plate 203, and a blocking plate 205 is fixedly connected to one end of the first connecting plate 204. Two second connecting plates 206 are symmetrically arranged on the outer wall of the circular sleeve plate 203, and an abutting plate 207 is fixedly connected to one end of the second connecting plate 206.

[0046] 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 circular plate. Such a setting 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 position of the top outer wall of the circular partition 3. The guide cylinder 201 is composed of two metal cylinders of different diameters. The other end of the guide cylinder 201 is fixedly connected to the top inner wall of the exposure chamber 103. The dust conveying pipe 104 mentioned above and the inner wall of the guide cylinder 201 are respectively installed with a one-way valve. The one-way valve is disclosed in the prior art, so it is not described in detail. Such an arrangement can guide the atomized dust suppressant discharged from the liquid atomizer 2 and the dust in the solid generator 101 into the lower chamber of the exposure chamber 103 respectively, and the mixed aerosol will not flow back into the guide cylinder 201 and the dust conveying pipe 104. One end of the four S-shaped elastic plates 202 is fixedly connected to the outer wall of the guide cylinder 201 and is distributed in a circular array. The S-shaped elastic plate 202 is an "S"-shaped plastic plate. The other ends of the four S-shaped elastic plates 202 are fixedly connected to the same circular sleeve plate 203. The circular sleeve plate 203 is Hollow plastic circular plate, two first connecting plates 204 are symmetrically fixedly connected to the outer wall of the circular sleeve plate 203, the first connecting plate 204 is a plastic straight plate, one end of the first connecting plate 204 is fixedly connected to a blocking plate 205, the blocking plate 205 is a plastic square plate, and its bottom end is provided with an arc, 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 plastic straight plates, the top outer walls of the two abutment plates 207 are fixedly connected to the bottom outer walls of the second connecting plates 206, and the abutment plates 207 are plastic straight plates.

[0047] When the abutment plate 207 receives the support force from the bottom end of the exposure cabin 103, it will be displaced in the direction away from the bottom of the exposure cabin 103, and will cause the second connecting plate 206 to be displaced in the same direction. At this time, the circular sleeve plate 203 will also be displaced in the direction of the displacement of the second connecting plate 206, causing the S-shaped elastic plate 202 to be deformed along the direction of its bending under the force. At the same time, the first connecting plate 204, the blocking plate 205, the circular sleeve plate 203, the second connecting plate 206 and the abutment plate 207 are an integrated structure, and the blocking plate 205 will be displaced following the displacement of the abutment plate 207. When the abutment plate 207 is no longer supported by the bottom end of the exposure chamber 103, the S-shaped elastic plate 202 will restore its deformation under the action of its own elasticity and push the circular sleeve plate 203 to move in the direction 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 direction of the circular sleeve plate 203. Subsequently, the blocking plate 205 and the abutment plate 207 will move respectively following the displacement of the first connecting plate 204 and the second connecting plate 206. Such a setting can open the blocking plate 205 by the force applied to the abutment plate 207, so that the mixed aerosol can leak from the blocking plate 205 into the lower chamber of the exposure chamber 103 to complete the mouse infection. When the abutment plate 207 is no longer subjected to force, it will be reset under the action of the elasticity of the S-shaped elastic plate 202 itself, and can wait for the next experiment.

[0048] like Figures 3 to 13 As shown, a brushless motor 301 is fixedly connected to the top outer wall of the circular partition 3, 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 a plurality of push teeth 308 are fixedly connected to the outer wall of one side of the first push rod 303. A connecting pipe 304 is fixedly connected to one end of the first piston tube 302, and the connecting pipe 304 has two bifurcated openings at one end away from the first piston tube 302, and the two bifurcated openings are respectively fixedly connected to the second piston tube 305, 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 the movable plate 4, and two second sliding grooves 401 are provided 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, and one end of the second spring 402 is fixedly connected to a connecting limit column 701. A vent hole 403 is provided on the top outer wall of the movable plate 4, and a ventilation support plate 404 is installed on the vent hole 403. Limit support columns 405 are symmetrically arranged on both sides of the top outer wall of the movable plate 4.

[0049] Specifically, the brushless motor 301 is fixedly connected to the top outer wall of the circular partition 3. The brushless motor 301 is publicly available in the prior art, so it is not 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 metal hollow cylinder. The first push rod 303 is slidably connected to the inner wall of the first piston tube 302 and can perform piston movement on the inner wall of the first piston tube 302. The first push rod 303 consists of two parts: a plastic square column and a plastic cylinder. A plurality of push teeth 308 are fixedly connected to the outer wall of one side of the first push rod 303 and are distributed in a linear array. The push teeth 308 can mesh with the gears on the brushless motor 301 and connect one end of the pipe 304. Fixedly connected to the outer wall of the bottom end of the first piston tube 302, the connecting pipe 304 is a plastic hose filled with liquid, and its end away from the first piston tube 302 has two forked openings, which are respectively fixedly connected to the outer walls of the bottom ends of the two second piston tubes 305. The second piston tube 305 consists of three parts: a hollow metal circular tube and two metal hollow circular plates. The second push rod 307 is slidably connected to the inner wall of the second piston tube 305, and can perform piston motion 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 circular plate.

[0050] When the brushless motor 301 rotates and drives the first push rod 303 to move toward the direction of the connecting pipe 304, it will push the liquid in the connecting pipe 304 to move toward the direction of the second piston tube 305. At this time, the second push rod 307 will be pushed by the liquid to move away from the connecting pipe 304. Conversely, when the brushless motor 301 rotates and drives the first push rod 303 to move away from the connecting pipe 304, it will drive 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 pushed by the liquid to move away from the connecting pipe 304. The second push rods 307 will be driven to move in the direction of the connecting pipe 304. The ends of the two second push rods 307 away from the second piston tube 305 are symmetrically fixedly connected to the two 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 toward 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 connecting limit column 701 is fixedly connected to the other end of the second spring 402. The connecting limit column 701 consists of two parts, a quarter plastic cylinder and a "convex" shaped plastic protrusion. The circular vent hole 403 is opened at the center of the outer wall of the top of the movable plate 4. The ventilation support plate 404 is installed on the inner wall of the vent hole 403. The ventilation support plate 404 consists of two parts, a plastic circular plate with a plurality of circular holes and a square plastic plate. Square protrusions are arranged on the outer wall of the circular plate at both ends of the square plastic plate. The limit support column 405 is symmetrically fixedly connected to the movable plate 4. Grooves with suitable square protrusions are arranged on both sides of the outer wall at the top of the middle part and at the end close to the air vent 403. Such an arrangement facilitates disassembly and installation. When the connecting limit column 701 is pulled to move in a direction away from the second spring 402, the second spring 402 will be subjected to force and move in the direction of its bending. The above structural arrangement can use the movable plate 4 to mix the solid dust and the atomized dust suppressant together when the brushless motor 301 rotates, and discharge them from the air vent 403, so that the concentration of the aerosol formed after the mixture can be evenly distributed, thereby improving the accuracy of the experiment.

[0051] like Figures 6 to 15As shown, the outer walls of the two second piston tubes 305 are respectively clamped with clamping plates 306, and the top outer walls of the two clamping plates 306 are respectively fixedly connected with the first fixing plate 5, and the outer walls at both ends of the first fixing plate 5 are symmetrically provided with C-shaped buckles 501, and the two ends of the outer wall of one side of the first fixing plate 5 are symmetrically provided with second fixing plates 509.

The inner wall of the first sliding groove 502 is slidably connected with an arc shovel plate 6, and the top inner wall of the first sliding groove 502 is fixedly connected with a first spring 504, and one end of the first spring 504 is fixedly connected with a connecting column 505, and one end of the connecting column 505 is fixedly connected with a limiting plate 503.

[0052] Specifically, the inner wall of the clamping plate 306 is clamped on the outer wall of the corresponding second piston tube 305. The clamping plate 306 is composed of two parts: an "L"-shaped metal plate and a "C"-shaped metal plate. The end of the clamping plate 306 with the "C"-shaped metal plate is clamped on the outer wall between the two metal hollow circular plates arranged near the top of the second piston tube 305. This not only facilitates the installation of the clamping plate 306 and the second piston tube 305, but also limits and fixes the second piston tube 305. The two first fixing plates 5 are respectively fixedly connected to the top outer walls of the two clamping plates 306. The first fixing plate 5 is a metal square plate, and its top is fixedly connected to the above-mentioned On the circular partition 3, the C-shaped clip 501 is symmetrically fixedly connected to the outer walls at both ends of the first fixed plate 5, the C-shaped clip 501 is a "C"-shaped plastic plate, one end of the two C-shaped support plates 506 is symmetrically fixedly connected to the two sides of the outer wall of the bottom end of the first fixed plate 5, the C-shaped support plate 506 is a "C"-shaped plastic plate, the other end of the C-shaped support plate 506 is fixedly connected with a fixed column, the fixed column is a plastic cylinder, the rotating cylinder 508 is rotatably connected to the outer wall of the fixed column, the rotating cylinder 508 is a hollow plastic cylinder, the two second fixed plates 509 are symmetrically fixedly connected to the two ends of the outer wall of the first fixed plate 5 close to the movable plate 4, and the second fixed plate 509 is a metal square plate.

[0053] The two first sliding grooves 502 are symmetrically opened at the two ends of the outer wall of the first fixed plate 5 close to the movable plate 4. The first sliding groove 502 is a square straight groove. One end of the arc shovel plate 6 is slidably connected to the inner wall of the first sliding groove 502. The arc shovel plate 6 is composed of three parts: a metal plate with an arc and two cylindrical plastic protrusions. One end of the first spring 504 is fixedly connected to the middle position of the inner wall at the top of the first sliding groove 502. The first spring 504 is disclosed in the prior art, so it is not described in detail. The other end of the first spring 504 is fixedly connected to the outer wall of one end of the connecting column 505 close to the top. The connecting column 505 is a plastic cylinder. The end of the connecting column 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 semicircular plastic plate, wherein the overall contour on the limiting plate 503 is adapted to the contour of the cylindrical plastic protrusion on the arc shovel plate 6.

[0054] When the brushless motor 301 rotates forward, it will drive the movable plate 4 to move toward the top inner wall of the exposure cabin 103, and will drive the arc shovel plate 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 shovel plate 6 will press 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 cabin 103. At this time, the first spring 504 will be stressed and deformed in its own bending direction until the ventilation support plate 404 on the movable plate 4 presses 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 opposite direction, the movable plate 4 will be pulled to move in the direction away from the circular partition 3. At this time, the first spring 504 will restore its deformation under the action of its own elasticity, pushing the limit plate 503 to move in the direction of the movable plate 4, and the arc shovel plate 6 will also move in the direction of the movable plate 4 under the push of the limit plate 503. During the displacement of the arc shovel plate 6, the outer wall on the side close 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. Such a structural setting can shovel up the agglomerates on the sterile pad 7 and pour out the shoveled agglomerates when the movable plate 4 moves toward the inner wall of the top of the exposure cabin 103.

[0055] The outer wall of the second fixed column 702 is fixedly connected with a sterile pad 7, the inner wall of the C-shaped buckle 501 is clamped with the second fixed column 702, the outer wall of the second fixed column 702 is fixedly connected with a dust storage box 8, the bottom of the dust storage box 8 is provided with a third sliding groove 801, and the inner wall of the third sliding groove 801 is slidably connected with a sliding plate 802. Specifically, one end of the two sterile pads 7 are respectively fixedly connected to the outer wall of the two second fixed columns 702 near the circular partition 3, in a mirror distribution, the sterile pads 7 are made of rubber, and are rolled on the outer wall of the rotating cylinder 508, and the other end is fixedly connected to the outer wall of the connecting limit column 701 near the second fixed plate 509.

[0056] When the movable plate 4 is displaced toward the top inner wall of the exposure chamber 103, the middle part of the sterile pad 7 will be limited by the rotating cylinder 508, and cooperate with the second sliding groove 401 to limit the connecting limiting column 701, so that the sterile pad 7 is attached to the top outer wall of the movable plate 4 during the displacement of the movable plate 4 toward the top inner wall of the exposure chamber 103, and pulls the connecting limiting column 701 to slide on the inner wall of the second sliding groove 401 toward the second fixed plate 509. At this time, the second spring 402 fixedly connected to the connecting limiting column 701 will be subjected to the pulling force of the connecting limiting column 701 and deformed along its own bending direction. When the movable plate 4 is displaced in the direction away from the top inner wall of the exposure chamber 103, the second spring 402 is no longer subjected to tension and recovers its deformation under the action of its own elasticity, pulling the connecting limit column 701 to slide along the inner wall of the second sliding groove 401 toward the ventilation support plate 404, and the sterile pad 7 fixedly connected to the outer wall of one side of the connecting limit column 701 will, driven by the connecting limit column 701, stick to the top outer wall of the movable plate 4 and slide toward the second fixed plate 509.

[0057] The outer wall of the second fixed column 702 is clamped onto the inner wall of the C-shaped buckle 501. The second fixed column 702 is a plastic cylinder. The dust box 8 is fixedly connected to the outer wall of the second fixed column 702. The dust box 8 is a plastic box with an open top. A third sliding groove 801 is provided at its bottom. 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 square plastic plates with semicircular protrusions are provided on both sides. The contour of the third sliding groove 801 is adapted to the contour of the sliding plate 802. When the device needs to be cleaned, it is only necessary to pull the handle to pull out the sliding plate 802, and the collected agglomerates can be easily cleaned out. Such a setting can collect and store agglomerates formed by the accelerated sedimentation of the atomized dust suppressant and dust, and can also clean out the agglomerates collected in the dust box 8 when the staff maintains the device.

[0058] The working principle of the technical solution of the present invention is as follows:

[0059] When in use, first put the mouse into the exposure chamber 103, and then use the gas pipeline to simultaneously input the atomized dust suppressant and the solid dust through the guide cylinder 201 and the dust conveying pipe 104 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. In the process of mixing the atomized dust suppressant and the solid dust, the agglomerates formed by the accelerated sedimentation will fall on the sterile pad 7. At this time, the brushless motor 301 can be started. When the brushless motor 301 rotates and drives the first push rod 303 to move toward the direction of the connecting pipe 304, it will push the connecting pipe The liquid in 304 is displaced toward the direction of the second piston tube 305. At this time, the second push rod 307 is pushed by the liquid to displace in the direction away from the connecting pipe 304. The movable plate 4 is displaced toward 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 will pull the connecting limit column 701 to slide on the inner wall of the second sliding groove 401 toward the direction of the second fixed plate 509. The second spring 402 is deformed along the direction of its bending under the tension.

[0060] The ventilation support plate 404 will move with the displacement of the movable plate 4, and will abut against the bottom outer wall of the abutment plate 207. When the abutment plate 207 receives the support force from the bottom end of the exposure cabin 103, it will move in the direction away from the bottom of the exposure cabin 103, and 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 displacement of the second connecting plate 206, causing the S-shaped elastic plate 202 to be deformed along the direction of its bending. At the same time, the first connecting plate 204 will move with the displacement of the circular sleeve plate 203, and will cause the blocking plate 205 to move in the direction of the displacement of the abutment plate 207. When the abutment plate 207 is no longer supported by the bottom end of the exposure cabin 103, the S-shaped elastic plate 202 will restore its deformation under the action of its own elasticity and push the circular sleeve plate 203 to move away from the top of the exposure cabin 103. At this time, the first connecting plate 204 and the second connecting plate 206 will also move in the direction of the circular sleeve plate 203, and then the blocking plate 205 and the abutment plate 207 will move respectively following the displacement of the first connecting plate 204 and the second connecting plate 206.

[0061] When the brushless motor 301 rotates forward and drives the first push rod 303 to displace in the direction of the connecting pipe 304, it will push the liquid in the connecting pipe 304 to displace in the direction of the second piston pipe 305. At this time, the second push rod 307 will be driven to displace away from the connecting pipe 304, and the movable plate 4 will displace in the direction of the inner wall of the top of the exposure chamber 103, driving the arc-shaped shovel plate 6 to displace along the inner wall of the first sliding groove 502 in the same direction. When the movable plate 4 displaces in the direction of the inner wall of the top of the exposure chamber 103, the middle of the sterile cushion cloth 7 will be limited by the rotating cylinder 508, and in cooperation with the limitation of the second sliding groove 401 on the connecting limit post 701, the sterile cushion cloth 7 will stick to the outer wall of the top of the movable plate 4 during the displacement of the movable plate 4 in the direction of the inner wall of the top of the exposure chamber 103, and pull the connecting limit post 701 to slide along the inner wall of the second sliding groove 401 in the direction of the second fixing plate 509. The arc-shaped shovel plate 6 can shovel up the agglomerates on the sterile cushion cloth 7. At the same time, during the displacement of the movable plate 4, the outer wall of the cylindrical plastic protrusion on the arc-shaped shovel plate 6 will abut against the bottom outer wall of the limiting plate 503 and drive the limiting plate 503 to displace along the inner wall of the first sliding groove 502 in the direction of the inner wall of the top of the exposure chamber 103. At this time, the first spring 504 will be stressed and deformed along the direction of its own bending until the ventilation support plate 404 on the movable plate 4 abuts the top outer wall of the abutting plate 207 against the bottom outer wall of the circular partition 3. At this time, the arc-shaped shovel plate 6 will be limited by the first sliding groove 502 and rotate under the guidance and abutment of the arc-shaped outer wall on the connecting limit post 701, and pour the shoveled agglomerates into the dust storage box 8 from the gap vacated after the displacement of the blocking partition 205. When the experiment is completed and the device needs to be cleaned and maintained, only need to pull the handle to draw out the sliding plate 802, and the collected agglomerates can be cleaned out. At the same time, the ventilation holes 403 originally covered by the two sterile cushion cloths 7 will be gradually opened during the displacement of the movable plate 4, and the mixed solid dust and atomized dust suppressant will also be discharged from the ventilation holes 403.

[0062] When the brushless motor 301 rotates in the reverse direction, it will drive the first push rod 303 to move in the direction away from the connecting pipe 304, and drive the liquid in the connecting pipe 304 to move in the direction away from the second piston tube 305. At this time, the second push rod 307 will be driven to move in the direction of the connecting pipe 304, and the movable plate 4 will be pulled to move in the direction away from the circular partition 3. At this time, the first spring 504 will restore its deformation under the action of its own elasticity, and push the limit plate 503 to move in the direction of the movable plate 4, and the arc shovel plate 6 will also be pushed by the limit plate 503 to move in the direction of the movable plate 4. During the displacement of the shovel plate 6, the outer wall on the side close 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, and the second spring 402 is no longer subjected to tension and recovers its deformation under the action of its own elasticity, which will pull the connecting limit column 701 to slide along the inner wall of the second sliding groove 401 toward the ventilation support plate 404, and the sterile pad 7 fixedly connected to the outer wall on one side of the connecting limit column 701 will be driven by the connecting limit column 701 to stick to the top outer wall of the movable plate 4 and slide toward the second fixed plate 509, and the two sterile pads 7 will cover the ventilation hole 403 again, waiting for the next round of experiments.
