Description
Technical Field
[0001] The utility model relates to the technical field of laboratory fume hoods, in particular to a fume hood with a drawer-type lower cabinet. Background Art
[0002] In the fume hood, the fume hood is generally a split structure with upper and lower parts. The upper cabinet includes the top air outlet, outer shell, column, guide plate and glass window, etc. The lower cabinet is a laboratory bench style, consisting of a laboratory table and a floor-standing cabinet.
[0003] The lower cabinet of the fume hood is generally a double-door storage cabinet with a depth of 500-600mm. Due to the low position and relatively deep depth of the cabinet, laboratory personnel need to squat and bend down to store items, which is very inconvenient and laborious. At the same time, when taking items, they may knock over other items and even break glass products. In addition, due to the depth of the cabinet, it is difficult to reach, which wastes the space behind and reduces space utilization. The above situations cause a certain degree of inconvenience to laboratory personnel when taking items.
[0004] Therefore, we provide pull-out fume hoods. Utility Model Content
