In addition, all the coupling/connection relationships mentioned herein do not mean that the components are directly connected, but mean that a better coupling structure can be formed by adding or reducing coupling accessories according to specific implementation conditions. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.

Referring to fig. 1 to 2, a fume hood includes a cabinet body 1. The upper part of the cabinet body 1 is connected with a ventilation pipe 11, and the ventilation pipe 11 is connected with a filtering structure 2. The filtering structure 2 comprises a filtering shell 21 and a filtering core 22, wherein a placing opening 211 is formed in the middle of the filtering shell 21, the placing opening 211 enables the cross section of the middle of the filtering shell 21 to be semicircular, and the filtering core 22 is placed in the filtering shell 21 through the placing opening 211. The filter shell 21 is hinged with a cover plate 23, the cover plate 23 is used for sealing the placing opening 211, and the cross section of the cover plate 23 is semi-circular and matched with the outer edge of the cover plate and the placing opening 211. The periphery fixedly connected with sealing washer of apron 23, the outer peripheral face of sealing washer with filter shell 21 looks butt, the sealing washer is sealed apron 23 and the handing-over department of filtering shell 21, avoids harmful gas or dust to spill over from apron 23 and the handing-over department of filtering shell 21, makes the peripheral environment of fume chamber keep nontoxic and clean. The cover plate 23 is far away from fixedly connected with hasp 24 between articulated one end and the filter shell 21, and the knot portion fixed connection of hasp 24 is on cover plate 23, and the hook portion fixed connection of hasp 24 is on filtering shell 21, and the knot portion and the hook portion of hasp 24 lock each other, play fixed effect to cover plate 23 and filter shell 21.

The inner wall at the middle part of the filter shell 21 is fixed with a positioning strip 212 through welding, the filter core 22 is provided with a positioning groove 221 matched with the positioning strip 212 in a clamping manner, the positioning strip 212 and the positioning groove 221 position the filter core 22, the filter core 22 is prevented from being displaced due to air flow, and the filter core 22 is difficult to take out from the placing opening 211.
