Description

BACKGROUND OF THE DISCLOSURE

Technical Field

The technical field relates to a positioning structure, and more particularly relates to a housing positioning structure for a ventilation fan.

Description of Related Art

A ventilation fan is often installed in an indoor environment to circulate indoor air. Additionally, the ventilation fan is generally installed in the ceiling to improve indoor air quality without occupying indoor space.

Moreover, in the existing ventilation fan, brackets are first combined with the housing of the ventilation fan, and then the housing is installed in the internal space of the ceiling. However, since the brackets require the use of a hand tool to secure multiple screws to the housing, the installation process is complicated and inconvenient. Furthermore, as ceilings in different areas may have different thicknesses, detailed planning is required before installation to ensure that the housing is securely installed and positioned, which is inconvenience during installation.

In view of the above drawbacks, the inventor proposes this disclosure based on his expert knowledge and elaborate researches in order to solve the problems of related art.
