[0002] The traditional kitchen smoke exhaust vent has a fixed structure and is difficult for users to disassemble without tools. However, the kitchen smoke exhaust vent works in an environment with a lot of oil smoke for a long time, and a lot of oil stains accumulate on the inner wall of the smoke exhaust vent. If the user does not clean the kitchen smoke exhaust vent regularly, the oil stains accumulated on the inner wall of the smoke exhaust vent will inevitably breed bacteria and viruses. It is time-consuming and laborious for the user to clean the smoke exhaust vent every time, which is very annoying.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a kitchen smoke exhaust vent that is easy to clean is provided in order to achieve a purpose with greater practical value. Utility Model Content
