[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. During the pretreatment of fecal samples for analysis inside the chamber, the chamber is sealed with a cover, and then the axial flow fan is started. The axial flow fan draws in odorous gases from inside the chamber, while outside air enters the chamber through the air inlet of the exhaust cover. Activated carbon mesh, located on the outer wall of the chamber and next to the axial flow fan, adsorbs odor molecules, thus treating the odor. Simultaneously, a downward-facing exhaust hood, located on the outer wall of the chamber and outside the activated carbon mesh, discharges the treated air downwards, contributing to a dry and slip-resistant laboratory floor.

[0015] 2. When the activated carbon mesh needs to be replaced periodically, push the elastic arm toward the side that is far apart from each other, so that the clips disengage from the bottom of the activated carbon mesh, and then the activated carbon mesh can be removed from the air outlet hood; then embed the new activated carbon mesh into the air outlet hood, with the upper side of the activated carbon mesh pressed against the pressure plate, and then use the clips at the lower end of the elastic arm to fasten it to the bottom of the activated carbon mesh, and use the positioning plate to position it, thereby completing the installation of the new activated carbon mesh, and finally realizing the convenient replacement of the activated carbon mesh;

The ultraviolet lamp strip can sterilize and disinfect the inside of the chassis. At the same time, the external airflow introduced into the air vent cover can pass through the ultraviolet lamp strip, thereby cooling the ultraviolet lamp strip and helping to extend the service life of the ultraviolet lamp strip.

[0019] 6. The filter screen installed inside the air inlet can filter the air introduced into the air inlet and prevent impurities from entering the chassis.

[0020] 7. The top of the cover is hinged to the top of the chassis, making it easy to open and close. Attached Figure Description

[0035] Principle: When pretreatment of fecal matter is performed inside the casing 1, the cover 2 seals the casing 1, and then the axial flow fan 3 starts to draw in the odor from the casing 1. At the same time, outside air enters the casing 1 through the air inlet 211 of the air intake cover 21. The activated carbon mesh 4, which is set on the outer wall of the casing 1 and located on one side of the axial flow fan 3, can adsorb odor molecules, thereby treating the odor. At the same time, the downward exhaust hood 5, which is wrapped on the outer wall of the casing 1 and located outside the activated carbon mesh 4, can discharge the treated air downwards, which helps to dry and prevent slipping of the laboratory floor.

[0036] While the axial flow fan 3 is used for deodorization, the ultraviolet lamp strip 6 inside the air vent cover 21 is also turned on. The ultraviolet lamp strip 6 can sterilize and disinfect the inside of the casing 1. At the same time, the external airflow introduced into the air vent cover 21 can pass through the ultraviolet lamp strip 6, thereby cooling the ultraviolet lamp strip 6 and helping to extend its service life.

[0037] When the activated carbon mesh 4 needs to be replaced periodically, the two elastic arms 53 are pushed away from each other by pushing the pressing plate 532, so that the buckle 531 is disengaged from the bottom of the activated carbon mesh 4, and then the activated carbon mesh 4 can be removed from the air outlet hood 5. Then, the new activated carbon mesh 4 is embedded in the air outlet hood 5, and the upper side of the activated carbon mesh 4 is pressed against the pressure plate 55. The buckle 531 at the lower end of the elastic arm 53 is used to fasten it to the bottom of the activated carbon mesh 4, and the positioning plate 51 is used for positioning, thereby completing the installation of the new activated carbon mesh 4. Finally, the activated carbon mesh 4 can be replaced conveniently.
