The invention provides a novel air guide laboratory
fume hood. The novel air guide laboratory
fume hood comprises a cabinet body, a door plate arranged at the bottom of the cabinet body, a test
bed isarranged in the middle of the cabinet body, the test
bed and the cabinet body are enclosed to form a test cavity, an air guide
pipe path and a
centrifugal fan are arranged at the top of the cabinet body, air flow is discharged outwards through the air guide
pipe path by the
centrifugal fan, the air guide
pipe path comprises an air guide main path and air guide branches, the
centrifugal fan is contained in the air guide main path, the air guide main path communicates with the air guide branches, one end of the air guide main path is connected with an
exhaust pipe, the other end of the air guide main path extends into the test cavity, the air guide branches are connected to the two sides of the air guide main path correspondingly, one ends of the air guide branches communicate with the airguide main path, the other ends of the air guide branches extend into the test cavity, air guide covers are arranged at the ends of the air guide branches, a
louver is arranged on the side of the cabinet body, and the
louver is located on the side of the test cavity. According to the novel air guide laboratory
fume hood, the air flow in each operation test position in the test cavity is ensured tobe guided and collected, and the air guide effective area and the air guide performance of the laboratory fume hood are improved.
