Description

Technical Field

[0001] The utility model relates to the technical field of fume hoods, in particular to a fume hood which is convenient for inspection and maintenance. Background Art

[0002] Fume hoods are similar to closed hoods. Small parts spray paint cabinets and chemical laboratory fume hoods are typical structures of cabinet exhaust hoods. Large room-type fume hoods have one side completely open, and operators work inside the cabinet. They are mainly used for large-scale painting, powder bagging, etc. The working opening of the fume hood has a great influence on the airflow distribution in the cabinet, and the airflow distribution directly affects the working effect of the cabinet exhaust hood.

[0003] After searching, the existing Chinese patent with announcement number CN202320611700.9 discloses a fume hood that is easy to maintain. When the fume hood body works and the internal power supply needs to be maintained and replaced after a certain period of use, the handle and the support block are slidably connected in the groove, and the sliding card plate drives the card head to move together, compressing the spring. After a certain period of time, the card head moves away from the card mouth, and the clamping of the sealing plate is released as a whole. At this time, the sealing plate is rotated by the rotating connection design of the rotating shaft and the turntable. When the sealing plate and the placement slot are in the same horizontal plane, the sealing plate is slid by the sliding connection design of the turntable and the sealing plate, so that the sealing plate is placed in the placement slot, and the electrical components inside the fume hood body can be inspected and replaced as a whole.

[0004] The above-mentioned technical scheme has the following defects: although such a fume hood structure can inspect and replace the inner wall circuit components through a cover plate that is easy to disassemble and assemble, in actual use, the circuit components are installed on the inner wall of the cabinet with a small space, and the actual replacement is relatively laborious. In order to further facilitate the inspection and maintenance of the electronic components of the fume hood control assembly, a fume hood that is easy to inspect and maintain is now proposed, which facilitates the overall transfer of the fume hood control assembly, so that the inspection and maintenance work can be carried out outside the cabinet, making the inspection and maintenance work of the fume hood more convenient.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
