Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a laboratory ventilation device, including a pipe 1, the pipe 1 is fixed on the top of the laboratory, and two ventilation devices are used together, one device exhausts air, and the other device supplies air, so as to realize ventilation of the laboratory. Filters 2 are fixedly connected at both ends of the pipe 1, and the filter 2 can ensure that dust does not enter the interior of the ventilation device, thereby ensuring the cleanliness of the interior. A fan 3 is fixedly connected to one side of the pipe 1 close to the filter 2, and the air inside the pipe 1 can be discharged to the right by starting the fan 3. At this time, the inlet on the left is connected to the laboratory, so as to realize the discharge of the air in the laboratory, and the other set of ventilation devices sends the outside air into the laboratory to complete the ventilation effect of the laboratory.

[0031] Reference Figure 1 , Figure 3 and Figure 5, brackets 4 are fixedly connected to both sides of the middle of the pipe 1, a metal pipe 5 is rotatably connected between the two brackets 4, and multiple atomizing nozzles 6 are installed on the outside of the metal pipe 5, a motor 7 is fixedly connected to the middle of one of the brackets 4, the left end of the metal pipe 5 is fixedly connected to the output end of the motor 7, a fixed sleeve 8 is rotatably connected to one side of the outer edge of the metal pipe 5, and the fixed sleeve 8 is fixedly connected to the middle of the right bracket 4, a water tank 9 is fixedly connected to the top of the pipe 1, a water pump 10 is fixedly connected to the bottom of the water tank 9, and a fixed pipe 11 is connected between the output end of the water pump 10 and the fixed sleeve 8. The motor 7 is started to drive the metal pipe 5 to rotate, and at this time, the water pump 10 is started to extract the disinfectant water inside the water tank 9 and inject it into the fixed sleeve 8 through the fixed pipe 11, and then the disinfectant water inside the fixed sleeve 8 enters the rotating metal pipe 5 through the water inlet 12. Then, while the metal pipe 5 rotates, the atomized disinfectant water is evenly sprayed on the inside of the pipe 1 through the atomizing nozzle 6, and the inside of the pipe 1 is fully disinfected to avoid the growth of mold substances. Ensure that the ventilation device is kept clean every time it is used, making the ventilation equipment safer and more stable during operation, and further ensuring that the environment inside and outside the laboratory is kept clean.

[0032] Reference Figure 1 , Figure 3 and Figure 5 A cleaning component is installed on the side of the pipe 1 away from the fan 3. The cleaning component can clean the filter 2 at the left air inlet to prevent it from being blocked by dust and other impurities generated in the laboratory. At the same time, the filter 2 can effectively prevent external dust from entering the laboratory when the device stops. The middle part of the fixed pipe 11 is fixedly connected to the top of the pipe 1, so that the fixed pipe 11 can be fixed on the pipe 1 and stably deliver the disinfectant water into the fixed sleeve 8. Two water inlet holes 12 are opened on the side of the metal pipe 5 close to the fan 3. The water inlet holes 12 are located inside the fixed sleeve 8. The disinfectant water inside the fixed sleeve 8 can be injected into the rotating metal pipe 5 through the water inlet holes 12, and then the disinfectant water is rotated and sprayed out through the atomizing nozzle 6, and the disinfectant water is atomized and evenly covered inside the pipe 1 for comprehensive disinfection.

[0033] Reference Figure 2 - Figure 4The cleaning assembly includes a rotating disk 13 and a fixed frame 15. The middle of the rotating disk 13 is fixedly connected to the output end of the motor 7. An eccentric shaft 14 is fixedly connected to one side of the edge of the rotating disk 13. A slide 18 is slidably connected to the outer periphery of the eccentric shaft 14. The inner side of the fixed frame 15 is fixedly connected to the side of the pipeline 1 away from the fan 3. A brush plate 16 is slidably connected to the middle of the fixed frame 15. An L-shaped bracket 17 is fixedly connected to the bottom of the brush plate 16. A connecting rod 19 is arranged between the L-shaped bracket 17 and the slide 18. When the motor 7 is started to disinfect the inside of the pipeline 1, the rotating disk 13 will also be driven by the motor 7 with two output shafts, so that the rotating disk 13 rotates to drive the eccentric shaft 14 to move in a circle, and the eccentric shaft 14 moves in a circle to pull the slide 18 and the connecting rod 19 to continuously reciprocate up and down. At this time, the L-shaped bracket 17 will also be pulled by the connecting rod 19 to reciprocate together, and then the brush plate 16 will be pulled by the L-shaped bracket 17 to move up and down on the inner side of the fixed frame 15 to clean the dust on the left fan 3 and avoid the accumulation of dust on the outside of the filter 2 due to exhaust. Ensure the unobstructed filter holes inside the filter 2 and ensure the stability of the ventilation volume of the device. The top of the connecting rod 19 is fixedly connected to the middle side of the bottom of the slide 18, and the bottom of the connecting rod 19 is fixedly connected to the bottom of the L-shaped bracket 17. Through the cooperation of the connecting rod 19 and the slide 18, the trend of circular motion can be converted into a trend of reciprocating motion up and down. The middle part of the connecting rod 19 is slidably connected to the bottom of the pipeline 1, so that the connecting rod 19 can only move up and down in a straight line when it moves, and then ensure that the eccentric shaft 14 pulls the slide 18 to reciprocate up and down when it moves. The brush plate 16 is in contact with the left filter screen 2, and the outer periphery of the L-shaped bracket 17 passes through the bottom of the fixing frame 15, so that when the L-shaped bracket 17 is pulled up and down, it can drive the brush plate 16 to clean the dust on the outside of the filter screen 2 to ensure the stability of its ventilation volume.

[0034] Working principle: By starting the fan 3, the air inside the pipe 1 can be discharged to the right side. At this time, the entrance on the left side is connected to the laboratory, so as to discharge the air inside the laboratory. Another set of ventilation devices sends the outside air into the laboratory to complete the ventilation effect of the laboratory. Then, the metal pipe 5 is driven to rotate by starting the motor 7. At this time, the water pump 10 is started to extract the disinfectant water inside the water tank 9 and inject it into the fixed sleeve 8 through the fixed pipe 11. Then, the disinfectant water inside the fixed sleeve 8 enters the rotating metal pipe 5 through the water inlet 12. Then, while the metal pipe 5 rotates, the atomized disinfectant water is evenly sprayed on the inside of the pipe 1 through the atomizing nozzle 6, and the inside of the pipe 1 is fully disinfected to avoid the growth of mold substances. Ensure that the ventilation device is kept clean every time it is used, so that the ventilation equipment is safer and more stable during operation, and further ensure that the environment inside and outside the laboratory is in a clean state.

[0035] At the same time, when the motor 7 starts to disinfect the inside of the pipe 1, the turntable 13 will also be driven by the motor 7 with two output shafts, so that the turntable 13 rotates to drive the eccentric shaft 14 to move in a circular motion, and the eccentric shaft 14 pulls the slide 18 and the connecting rod 19 to continuously reciprocate up and down through the circular motion. At this time, the L-shaped bracket 17 will also be pulled by the connecting rod 19 to reciprocate together, and then the brush plate 16 is pulled by the L-shaped bracket 17 to move up and down on the inside of the fixed frame 15 to clean the dust on the left fan 3 and avoid dust accumulation on the outside of the filter 2 due to exhaust. Ensure the unobstructed filter holes inside the filter 2 and ensure the stability of the ventilation volume of the device.
