Embodiment 1

[0044] Embodiment 1: The workbench 1 is placed horizontally through universal wheels, and the experimental items can be placed in the storage cabinet 17. The fan 19, the motor 3 and the electric push rod 14 are electrically connected to the external distribution box through cables. When in use, control two The electric push rod 14 runs, and the electric push rod 14 drives the two adjustment plates 4 to move to both sides of the shaft rod 2, so that the two second driving bevel gears 6 mesh with the two second driven bevel gears 12. At this time, the control The motor 3 runs, the motor 3 drives the shaft 2 to rotate, the shaft 2 drives the two second driving bevel gears 6 to rotate, the two second driving bevel gears 6 rotate through the two second driven bevel gears 12, and the two second The driven bevel gear 12 drives the two rotating cylinders 13 to rotate. Since the screw rod 16 is threadedly connected with the rotating cylinder 13, when the rotating cylinder 13 rotates clo...

Abstract

The embodiment of the invention discloses a new type of laboratory fume hood, which includes a workbench, a shaft is movable in the center of the inner cavity of the workbench, a motor is fixed on one side of the workbench, and the shaft It is connected with the motor through the output shaft transmission, and both sides of the shaft are provided with adjustment plates, and the two adjustment plates are slidingly connected with the shaft, and the adjacent sides of the two adjustment plates are movable. A driving bevel gear. The present invention uses a motor to drive the cabinet to move up and down, so that people of different heights can use it. The electric push rod drives the two first active bevel gears to move to the middle of the shaft. The motor can drive the two exhaust fans to rotate to generate air flow, which moves to the On the top of the workbench, the fan is used to speed up the air exchange at the top of the workbench. The fume hood has the function of lifting and double exhaust at the same time.

Description

technical field [0001] The invention relates to the technical field of laboratory ventilation, and more specifically, the invention relates to a novel laboratory fume hood. Background technique [0002] The fume hood is an indispensable part of the laboratory ventilation design. In order to prevent laboratory workers from inhaling or swallowing some toxic, pathogenic or unknown toxic chemicals and organisms, there should be good ventilation in the laboratory. Ventilation. In order to prevent the absorption of some vapors, gases and particles (smoke, soot, dust and aerosols), pollutants must be removed by means of fume hoods, fume hoods or local ventilation; [0003] The prior art has the following deficiencies: the fume hood is designed with a fixed structure, which is inconvenient to adjust and use, and the use range is narrow, and the ventilation effect of the fume hood is poor. During use, multiple driving mechanisms are required to drive and run, and the production and u...
