The left and right side walls of the bottom box 1 are fixedly connected with a protective net 35 adapted to the ventilator 31. The protective net 35 prevents mice or larger particles from entering the interior of the ventilator 31, and the inner wall of the bottom box 1 is fixedly connected with a standing plate 37, which provides a standing space for the mice to separate from the upper surface of the leaking plate 6. The upper surface of the upper box 2 is clamped with a cover plate 36, and the inside of the bottom box 1 can be cleaned or observed more directly by separating the cover plate 36 from the upper surface of the upper box 2.

[0032] The inner bottom wall of the bottom box 1 is fixedly connected with an annular piston cylinder 3, and the annular piston plate 4 slidably connected to the inner wall of the annular piston cylinder 3 is fixedly connected to the leak plate 6 inside the bottom box 1 through the annular cylinder 5. The leak plate 6 is slidably connected to the inner wall of the bottom box 1. A through groove 7 is provided on the inner bottom wall of the bottom box 1, and a collecting box 8 is clamped on the bottom surface of the bottom box 1. The through groove 7 is located directly above the collecting box 8. A dust collecting box 9 is fixedly connected to the outer surface of the collecting box 8. A dust collecting net 15 is inlaid on the bottom surface of the dust collecting box 9, and the upper surface of the dust collecting box 9 is clamped with the bottom surface of the bottom box 1. The dust collecting net 15 filters and collects small particles such as dust and wood chips that flow in. A group of first one-way valves 10 are inlaid on the outer surface of the annular piston cylinder 3, and the annular piston cylinder 3 A group of second one-way valves 11 connected to the dust collecting box 9 are fixedly connected to the inner bottom wall, the air inlet end of the first one-way valve 10 is connected to the interior of the bottom box 1, and the air outlet end of the first one-way valve 10 and the air inlet end of the second one-way valve 11 are both connected to the interior of the annular piston cylinder 3, and the air outlet end of the second one-way valve 11 is connected to the interior of the dust collecting box 9, ensuring the flow direction of air inside the annular piston cylinder 3, and a group of first motors 12 are fixedly connected to the outer surface of the bottom box 1, and the output end of each first motor 12 is fixedly connected to an eccentric wheel 13 slidably connected to the bottom surface of the leak plate 6, and the output end of the first motor 12 does not contact the penetration point of the bottom box 1, and the eccentric wheel 13 is always in contact with the bottom surface of the leak plate 6.

[0033] The first motor 12 drives the leak plate 6 to move upward, and then the leak plate 6 can move downward under the action of sawdust and its own gravity. During the process, the mouse stands on the upper surface of the standing plate 37, that is, the operation of the first motor 12 causes the eccentric wheel 13 to drive the leak plate 6 to vibrate up and down, which is conducive to the smaller particles and other impurities on the upper surface of the leak plate 6 falling into the interior of the collecting box 8. At the same time, the annular piston plate 4 moves up and down inside the annular piston cylinder 3, and the smaller particles such as dust inside the bottom box 1 follow the air through the leak plate 6, the first one-way valve 10, the annular piston cylinder 3 and the second one-way valve 11 to flow to the interior of the dust collecting box 9, and are collected in the interior of the dust collecting box 9 under the filtering action of the dust collecting net 15. The collection box 8 and the dust collecting box 9 can be separated from the bottom surface of the bottom box 1 to clean the impurities inside the collection box 8 and the dust collecting box 9, slowing down the sticking or agglomeration of sawdust or smaller impurities on the upper surface of the leak plate 6, and extending the service life of the sawdust inside the device. At the same time, the cleanliness of the internal environment of the device is improved, and the impact of the deterioration of the living environment on the observation experiment of small animals is reduced, thereby reducing the workload of daily maintenance and the waste of resources.

[0034] The upper surface of the leak plate 6 is slidably connected with a scraper 14, and the outer surface of the scraper 14 is inlaid with a group of first check valves 29, and the outer surface of the straight cylinder 26 is inlaid with a second check valve 30. The air outlet end of each first check valve 29 is connected to the interior of the bottom box 1, and the air inlet end of the second check valve 30 is connected to the interior of the bottom box 1, and the air outlet end of the second check valve 30 and the air inlet end of each first check valve 29 are connected to the interior of the straight cylinder 26. That is, when the leak plate 6 vibrates up and down, it drives the scraper 14 to move up and down, so that the piston rod 27 moves up and down on the inner wall of the straight cylinder 26. During this process, the air inside the bottom box 1 passes through the second check valve 30, the straight cylinder 26, the piston rod 27 and the first check valve. The valve 29 flows out, which better cooperates with the scraper 14 to scrape away impurities such as agglomerated sawdust. The outer surface of the bottom box 1 is provided with a pair of first slide grooves 16 and second slide grooves 17. The inner walls of the two first slide grooves 16 and the second slide grooves 17 are respectively slidably connected with the first slider 18 and the second slider 19. The one-way valve and the check valve are an important component in the fluid control system. Its main function is to control the one-way flow of the fluid. When the fluid flows into one end of the one-way valve, the valve will open and allow the fluid to pass; and when the fluid tries to flow in from the other end in the opposite direction, the valve will close and prevent the flow of the fluid. This characteristic makes the one-way valve play an irreplaceable role in many industries and applications.

[0035] The outer surface of the first slider 18 on one side is fixedly connected to the second motor 20, and the first reciprocating screw 21 fixedly connected to the output end of the second motor 20 is rotatably connected to the first slider 18 on the other side. The outer surface of the first reciprocating screw 21 is threadedly connected to the first nut 22, which drives the subsequent scraper 14 to move left and right on the upper surface of the leaking plate 6. The inner wall of the straight cylinder 26 fixedly connected to the outer surface of the first nut 22 is slidably connected to the piston rod 27, and the piston rod 27 is fixedly connected to the outer surface of the scraper 14. The inner top wall of the straight cylinder 26 is fixedly connected to the telescopic spring 28. Figure 1 and Figure 5 The telescopic springs 28 are all in a natural state, and the bottom ends of the telescopic springs 28 are fixedly connected to the piston rod 27. The setting of the telescopic springs 28 has a buffering effect on the movement of the scraper 14 on the upper surface of the leak plate 6. The outer surface of the second slider 19 on one side is fixedly connected to the third motor 23, and the second reciprocating screw rod 24 fixedly connected to the output end of the third motor 23 is rotatably connected to the second slider 19 on the other side. The second nut 25 threadedly connected to the outer surface of the second reciprocating screw rod 24 is fixedly connected to the first nut 22, driving the scraper 14 to move back and forth on the upper surface of the leak plate 6, so that the scraper 14 has a better scraping and cleaning effect on the upper surface of the leak plate 6.

[0036] Working principle: When in use, the first motor 12, the second motor 20, the third motor 23 and the fan 32 are connected to the mobile power supply. The operation of the first motor 12 causes the eccentric wheel 13 to drive the leak plate 6 to vibrate up and down. During the process, the mouse stands on the upper surface of the standing plate 37, which is conducive to the dust, sawdust and other smaller particles on the upper surface of the leak plate 6 falling into the collection box 8. At the same time, the annular piston plate 4 moves up and down inside the annular piston cylinder 3, and the dust and other smaller particles inside the bottom box 1 follow the air through the leak plate 6, the first one-way valve 10, the annular piston cylinder 3 and the second one-way valve 11 to flow into the dust collecting box 9, and are collected in the dust collecting box 9 under the filtering action of the dust collecting net 15, which slows down the sticking or agglomeration of sawdust or smaller impurities on the upper surface of the leak plate 6, and prolongs the installation time. While extending the service life of the internal sawdust, the internal environment of the device is improved and the cleanliness of the device is reduced, and the impact of the deterioration of the living environment on the observation experiment of small animals is reduced, thereby reducing the workload of daily maintenance and the waste of resources. The second motor 20 and the third motor 23 work to drive the scraper 14 to move back and forth and left and right on the upper surface of the leak plate 6, so that the scraper 14 has a scraping effect on the upper surface of the leak plate 6. When the leak plate 6 vibrates up and down, it drives the scraper 14 to move up and down, so that the piston rod 27 moves up and down on the inner wall of the straight cylinder 26. During the process, the air inside the bottom box 1 flows out through the second check valve 30, the straight cylinder 26, the piston rod 27 and the first check valve 29, which better cooperates with the scraper 14 to scrape away impurities such as agglomerated sawdust, and further improves the cleanliness of the internal environment of the device.
