Abstract

The invention discloses a ventilation fan with a protection mechanism. The ventilation fan comprises a fan mounting cylinder, wherein a driving device is fixedly installed in the middle of an inner cavity of the fan mounting cylinder, a blade assembly is fixedly installed in the center of the top of the driving device, and dustproof nets are symmetrically and fixedly installed at the top and the bottom of the inner cavity of the fan mounting cylinder; connecting rings are symmetrically and fixedly connected to the two ends of the top and the bottom of the fan mounting cylinder, first rotating grooves are symmetrically formed in the left sides and the right sides of the opposite side faces of the two connecting rings, first guide columns are fixedly connected to the centers of the inner walls of the bottoms of the first rotating grooves, and protective cylinders are symmetrically arranged at the top and the bottom of the fan mounting cylinder. The ventilation fan has the beneficial effects that through cooperative work of the arranged protective cylinders and sand prevention nets, gravel is intercepted, and protection is provided for the blade assembly; and pressing rings move on the connecting columns, so that clamping and fixing of U-shaped fixing clamping plates to the connecting rings and mounting rings are completed, and a solid foundation is provided for connection of the fan mounting cylinder and the protective cylinders.

Description

technical field [0001] The invention relates to the technical field of ventilation fans, in particular to a ventilation fan with a protection mechanism. Background technique [0002] Ventilation fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine and is widely used in factories, mines, tunnels, ships and buildings for ventilation and dust removal, boilers and industrial furnaces. Ventilation and induction of air, cooling and ventilation in air conditioning equipment and household appliances, etc. [0003] Existing ventilation fans need to connect the indoors with the outdoors, so as to discharge the indoor air to the outdoors, but the existing ventilation fans do not have a protective structure, so foreign stones and other impurities can easily enter the interior of the ventilation fan, which can easily cause damage to the ventilation fan . Contents of the invention [0004] The main purpose of ...
