Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically a fumigation device for rat airway inflammation experiments. Background Technology

[0002] In the smoke fumigation experiment for rat airway inflammation, a smoke chamber is required. Existing technology, patent document CN210470662U, discloses an experimental rat smoke fumigation device, including a chamber, a movable top cover, a smoke inlet valve, and an adjustable-speed fan. The top of the chamber is equipped with a sealing plate, and the movable top cover is connected above the sealing plate. A smoke inlet valve is located on the lower part of one side of the chamber, and slots are provided on the inner side of the chamber, with smoke diffusion plates installed between the slots. This utility model features a duckbill-style design for the smoke inlet valve, effectively reducing smoke loss and improving smoke utilization efficiency. Smoke diffuses through diffusion holes on the surface of the smoke diffusion plate, quickly and evenly entering the rat's activity chamber. The adjustable-speed fan then exhausts air outwards, creating a negative pressure environment inside the chamber, which improves smoke intake efficiency. The smoke intake speed can be adjusted by changing the speed of the adjustable-speed fan, thereby adjusting the smoke concentration inside the chamber. Furthermore, wire mesh installed on the inner and outer sides of the adjustable-speed fan ensures the safety of the rats and experimenters during the experiment.

[0003] In the experiment, multiple groups of rats are usually required for comparison. The existing fumigation device is too simple, making it inconvenient to store rats in groups and to handle them, which brings many inconveniences to the use and needs to be further improved.
