Description

Technical Field

[0001] This utility model relates to the field of reagent cabinet technology, specifically a reagent cabinet with an exhaust structure. Background Technology

[0002] Reagent cabinets are specialized equipment used in laboratories to store chemical reagents and hazardous materials. They are usually made of metal, wood, or corrosion-resistant plastic and have multi-layered shelves, drawers, or lockable cabinet doors. They can be used to store reagents of different properties in different categories. Some models are equipped with ventilation systems to prevent the accumulation of harmful gases and ensure safe management and a clean space.

[0003] Existing reagent cabinets often suffer from minor gas leaks, leading to reactions between gases from different reagent bottles. This can result in the generation of hazardous gases or accelerated evaporation of gases from the bottles. Some gases also settle in the dead corners of the cabinet's ventilation system, affecting subsequent experimental procedures and results. To address these issues, this invention provides a reagent cabinet with an exhaust ventilation system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a reagent cabinet with an exhaust structure, which solves the problem that in existing reagent cabinets, even slight gas leaks from reagent bottles can cause reactions between gases of different properties, with some gases settling in the dead corners of the cabinet's exhaust system, resulting in the generation of harmful gases or accelerated evaporation of gases from the reagent bottles, thus affecting subsequent experimental procedures and results.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A reagent cabinet with an exhaust structure includes a reagent cabinet, which has six sets of isolation chambers.

The exhaust collection device is installed in the middle section of the reagent cabinet. The exhaust collection device includes a collection air box and an input inclined air duct. The input inclined air duct is used to transport air from different isolation chambers into the collection air box. The exhaust fan and the collection air box are connected. The air inlet guide device is installed on the side wall of the reagent cabinet. The air inlet guide device is respectively installed on the side wall of the six sets of isolation chambers.

[0006] Preferably, the reagent cabinet has an air inlet slot on its side. The air inlet guide includes a fixing ring, a guide plate, and an air inlet chute. The fixing ring is fixedly connected in the air inlet slot. The guide plate array is fixed in the air inlet slot. The air inlet chute is opened between two sets of guide plates. The inclination directions of the air inlet chute on the left and right sides are opposite to each other. The air inlet chute is used to blow airflow out to the front and rear sides of the isolation chamber.

[0007] Preferably, the reagent cabinet is equipped with symmetrical placement plates on the left and right sides, the collecting air box is installed between the two sets of placement plates, the isolation chamber is formed by the placement plates, the placement plates are used to place six sets of reagent bottles of different properties, and the front end of the reagent cabinet is rotatably connected to a cabinet door.
